    ITEM 1. BUSINESS

    General
    The Columbia Gas System, Inc. (the Corporation) organized under the laws of
    the State of Delaware on September 30, 1926, is a registered holding
    company under the Public Utility Holding Company Act of 1935, as amended,
    (1935 Act) and derives substantially all its revenues and earnings from the
    operating results of its 19 direct subsidiaries.  On July 31, 1991, the
    Corporation and its wholly-owned subsidiary, Columbia Gas Transmission
    Corporation (Columbia Transmission), filed separate petitions for
    protection under Chapter 11 of the Federal Bankruptcy Code.  Both the
    Corporation and Columbia Transmission are debtors-in-possession under the
    Bankruptcy Code and continue to operate their businesses in the normal
    course subject to the jurisdiction of the United States Bankruptcy Court
    for the District of Delaware.  The Corporation owns all of the securities
    of its subsidiaries except for approximately 10 percent of the stock in
    Columbia LNG Corporation.  The Corporation's subsidiaries are engaged in
    exploration for and production of oil and natural gas, natural gas
    transmission, natural gas distribution and other energy operations.  In
    addition, Columbia Gas System Service Corporation provides data processing,
    financial, accounting, legal and other services for the Corporation and
    other affiliates.  The Corporation and its subsidiaries are sometimes
    referred to herein as the System.

    Oil and Gas Operations
    The Corporation's oil and gas subsidiaries, Columbia Gas Development
    Corporation and Columbia Natural Resources, Inc., explore for, develop,
    produce, and market oil and natural gas in the United States.  These
    companies hold interests in more than two million net acres of gas and oil
    leases and have proved oil and gas reserves in excess of 750 billion cubic
    feet of gas equivalent.

    Operations are focused in the Appalachian, Arkoma, Michigan, Permian,
    Powder River and Williston basins; both onshore and offshore in the Gulf
    Coast areas of Texas and Louisiana, and in Utah and California.  Offshore
    holdings include interests in federal blocks, most of which are located in
    the West Cameron, Vermilion, Eugene Island, and Ship Shoal areas of the
    Gulf of Mexico.

    Transmission Operations
    The Corporation's two interstate pipeline transmission companies, Columbia
    Transmission and Columbia Gulf Transmission Company (Columbia Gulf),
    operate a 23,700-mile pipeline network that extends from offshore in the
    Gulf of Mexico to New York State and the eastern seaboard.  In addition,
    Columbia Transmission operates one of the nation's largest underground
    storage systems.

    Historically, Columbia Transmission offered both a wholesale sales service
    and a transportation service to local distribution companies.  However,
    when a new federally mandated business restructuring of the industry took
    effect in late 1993, Columbia Transmission expanded its transportation and
    storage services for local distribution companies and industrial and
    commercial customers and now provides only a minimal sales service.
    Columbia Gulf's pipeline system, which extends from offshore Louisiana to
    West Virginia, carries a major portion of the gas delivered by Columbia
    Transmission.  It also transports gas for third parties within the
    production areas of the Gulf Coast.  Columbia Gulf owns interests in the
    Overthrust, Ozark and Trailblazer pipelines, which extend into major
    midcontinent and western gas-producing areas.  Combined, Columbia
    Transmission and Columbia Gulf serve customers in 15 northeastern, middle
    Atlantic, midwestern, and southern states and the District of Columbia.

    Columbia LNG Corporation has announced plans to initiate peaking services
    from its Cove Point LNG facility by the end of 1995.

    Distribution Operations
    The Corporation's five distribution subsidiaries provide natural gas
    service to more than 1.9 million residential, commercial and industrial
    customers in Ohio, Pennsylvania, Virginia, Kentucky, and Maryland.  These
    subsidiaries purchase gas supplies to serve their high-priority customers
    and transport gas for industrial and commercial customers who purchase gas
    from other sources.  More than 28,000 miles of distribution pipelines serve
    such major





                                       3

    ITEM 1.  BUSINESS (Continued)

    markets as Columbus, Lorain, Parma, Springfield, and Toledo in Ohio;
    Gettysburg, York and a part of Pittsburgh in Pennsylvania; Lynchburg,
    Staunton, Portsmouth and Richmond suburbs in Virginia; Ashland, Frankfort
    and Lexington in Kentucky; and Cumberland and Hagerstown in Maryland.

    Other Energy Operations
    The Corporation's TriStar Ventures Corporation participates in natural
    gas-fueled cogeneration projects that produce both electricity and useful
    thermal energy.

    Two subsidiaries, Columbia Propane Corporation and Commonwealth Propane,
    Inc., sell propane at wholesale and retail to approximately 68,000
    customers in six states.

    In the Appalachian area, Columbia Coal Gasification Corporation another
    subsidiary owns over 500 million tons of coal reserves, much of which
    contains less than one percent sulfur.  Approximately 50 percent of the
    total reserves are leased to other companies for development.

    Columbia Energy Services oversees the System's nonregulated natural gas
    marketing efforts and provides an array of supply and fuel management
    services to distribution companies, independent power producers and other
    large end users both on and off the transmission and distribution
    subsidiaries' pipeline systems.

    Columbia Gas System Service Corporation provides centralized,
    cost-efficient data processing, financial, accounting, legal, and other
    services for the Corporation and other operating subsidiaries.

    For additional discussion of the System's business segments, including
    financial information for the last three fiscal years, see Item 7, page 19
    through 52 and Note 16 on page 93 of Item 8.

    Other Relevant Business Information
    The System's customer base is broadly diversified, with no single customer
    accounting for a significant portion of sales or transportation revenues.

    The Corporation's operating subsidiaries are subject to competitive
    pressures from other pipeline systems and producers that sell and/or
    transport natural gas as well as from competition from alternative fuels,
    primarily oil and electricity.  The oil and gas subsidiaries compete in the
    marketplace for sales of their oil and gas production through a combination
    of long-term contracts and spot sales.  The transportation subsidiaries
    compete in the highly competitive northeast and midwest energy markets. The
    distribution subsidiaries compete with alternative fuels and to a limited
    extent with other gas companies.

    Certain subsidiaries file reports with various federal agencies containing
    estimates of company-owned oil and gas reserves.  These estimates are
    generally consistent but not always comparable to those reported in the
    1993 Annual Report to Shareholders.

    At January 31, 1994, the System had 10,114 full-time employees of which
    2,089 are subject to collective bargaining agreements.

    Information relating to environmental matters is detailed in Item 7 pages
    33 through 34, page 41 and page 46 and in Item 8, Note 12H on pages 87
    through 91.

    For a listing of the subsidiaries of the Corporation and their lines of
    business refer to Exhibit 22.

    Public Utility Holding Company Act of 1935
    The Corporation and its subsidiaries are subject, in certain matters, to
    the jurisdiction of the Securities and Exchange Commission (SEC) under the
    1935 Act.  In 1944, the SEC held that the major portions of the System
    complied with the requirements of Section 11 of the 1935 Act relating to a
    "single integrated public-utility system" and businesses reasonably
    incidental thereto, but the SEC reserved jurisdiction over the
    retainability of certain subsidiaries.





                                       4
<PAGE>   5
    ITEM 1.  BUSINESS (Continued)

    Included were two companies owning pipelines in West Virginia and Northern
    Virginia extending into Maryland and New York (the reserved pipelines are
    now part of Columbia Transmission) and Virginia Gas Distribution
    Corporation (now a part of Commonwealth Gas Services, Inc.). Since that
    time, the reservation of jurisdiction has been expanded to include the
    subsequently acquired properties of Blue Ridge Gas Company (a Virginia
    retail company which is now part of Commonwealth Gas Services, Inc.),
    Commonwealth Gas Pipeline Corporation (now a part of Columbia Transmission)
    and a retail subsidiary (Commonwealth Gas Services, Inc.) acquired as a
    result of the merger of the Corporation with Commonwealth Natural
    Resources, Inc. and Lynchburg Gas Company, (now a part of Commonwealth Gas
    Services, Inc.).

    The Corporation filed a motion with the SEC in June 1955 requesting the
    termination of such reserved jurisdiction.  After hearings, no further
    action has been taken and the Corporation is unable to predict whether or
    when the SEC will finally dispose of the Corporation's 1955 motion and
    resolve the retainability issue.

    The Gas Related Activities Act (GRAA), enacted in 1990, provides that gas
    transmission is deemed to be reasonably incidental or economically
    necessary or appropriate to the operation of the gas utility system under
    Section 11 of the 1935 Act.  Since the basis for questioning the
    retainability of the gas transmission pipelines was compliance with this
    Section 11 criteria, the passage of the GRAA supports, and should resolve,
    the retainability of the gas transmission pipelines.

    If however, any of these properties were ultimately to be held not
    retainable, management believes that the SEC would permit the Corporation
    to adopt a plan for orderly disposition which would permit full realization
    of their intrinsic values.

    ITEM 2. PROPERTIES

    Information relating to properties of subsidiary companies is detailed on
    pages 6 through 7 herein and pages 96 through 99 of Item 8 under Note 18.
    The System also owns coal interests in the Appalachian area.  Assets under
    lien and other guarantees are described on page 86 in Note 12E of Item 8.

    Neither the Corporation nor any subsidiary knows of material defects in the
    title to any real properties of the subsidiaries of the Corporation or of
    any material adverse claim of any right, title, or interest therein,
    pending or contemplated except the Official Committee of Unsecured
    Creditors of Columbia Transmission has filed a complaint which challenges
    the 1990 property transfer from Columbia Transmission to Columbia Natural
    Resources, Inc. as an alleged fraudulent transfer.  Substantially all of
    Columbia Transmission's property has been pledged to the Corporation as
    security for First Mortgage Bonds issued by Columbia Transmission to the
    Corporation  which has also been challenged by the Official Committee of
    Unsecured Creditors of Columbia Transmission.

           Resources, Inc. as an alleged fraudulent transfer.  Substantially all
           of Columbia Transmission's property has been pledged to the

    ITEM 3.  LEGAL PROCEEDINGS

    I.   Shareholder Class Actions and Derivative Suits (Unless otherwise
    noted, all matters are stayed pursuant to Section 362 of the Bankruptcy
    Code)

         Since the June 19, 1991 announcement by the Board of Directors
    regarding the Corporation's proposed charge to second quarter earnings and
    suspension of its dividend, seventeen complaints including suits purporting
    to be class actions, or alleging claims common to the purported class
    actions, have been filed in the U.S. District Court for the District of
    Delaware.  These actions have been consolidated under the style In re
    Columbia Gas Securities Litigation, Consol. C.A. No. 91-357.  Although an
    amended and consolidated complaint has yet to be filed, the preconsolidated
    complaints variously named the Corporation, then current members of its
    Board of Directors, certain officers, the Corporation's independent public
    accountants, and the Corporation's underwriters for its 1990 common stock
    offering as defendants (the Defendants).

         These complaints generally allege the Defendants publicly made
    material misleading statements during the relevant class periods (from
    February 28, 1990 to June 19, 1991) concerning the Corporation's financial
    condition, and failed to disclose material facts which rendered other
    statements misleading, thereby artificially inflating the market price of
    the Corporation's common stock and publicly traded debt securities, causing
    the various plaintiffs and other class members to purchase such publicly
    traded securities at artificially inflated prices.  The complaints allege
    violations of Sections 11, 12(2) and 15 of the Securities Act of 1933,
    Sections 10(b), 20(a) and Rule 10b-5 of the Securities Exchange Act of
    1934, negligent misrepresentations, and common law fraud and deceit.

         In addition to the above-referenced class actions, three derivative
    stockholder actions have been filed in the Court of Chancery of the State
    of Delaware.  These cases have been consolidated under the style In Re
    Columbia Gas Derivative Litigation.  The complaints in these actions name
    as defendants the Board of Directors and the Corporation (nominal).  The
    complaints generally allege that the members of the Board of Directors
    breached their fiduciary duties to the Corporation by failing to make
    required disclosures thereby causing the Corporation to be subjected to
    federal securities law liabilities.

    II.      Bankruptcy Matters

         A.  Matters in the United States Bankruptcy Court for the District of
             Delaware

             1. Columbia Gas Transmission Corporation v. The Columbia Gas
    System, Inc. and Columbia Natural Resources, Inc.,  C.A.  No. 92-35.  (U.S.
    Bankruptcy Ct. Dist. of Delaware, filed March 18, 1992).  The Official
    Committee of Unsecured Creditors of Columbia Transmission filed a complaint
    (the Intercompany Complaint) challenging the status of approximately $1.7
    billion of debt owed by Columbia Transmission to the Corporation and the
    transfer of natural resource properties representing 450 billion cubic feet
    of natural gas reserves and one million barrels of oil reserves to Columbia
    Natural Resources, Inc. (Columbia Natural Resources) as well as other
    intercompany transactions.

                On May 14, 1992, the Official Committee of Unsecured Creditors
    of Columbia Transmission filed a motion to withdraw the jurisdictional
    reference to the U.S. District Court for the District of Delaware and filed
    a demand for a jury trial.  On February 9, 1993, the motion was denied by
    the U. S. District Court and on August 20, 1993, the Third Circuit denied
    the appeal by the Official Committee of Unsecured Creditors of Columbia
    Transmission of the District Court's order allowing resolution of the
    Intercompany Complaint before the Bankruptcy Court.

                On June 11, 1992 the Corporation filed a motion and supporting
    brief for partial dismissal or, in the alternative partial summary judgment
    with respect to certain counts of the complaint which was supported by
    Columbia's Equity Security Holders Committee and Unsecured Creditors
    Committee.  The motion has been fully briefed and a pretrial schedule has
    been established which, if followed, would result in a trial of the
    Intercompany

    ITEM 3.   LEGAL PROCEEDINGS (Continued)

    Complaint in the spring of 1994.  There has been no indication as to when
    the Bankruptcy Court might act on Columbia's motion for summary judgment.

             2. Motion to Fix Procedures to Establish Columbia Transmission's
    Liability to Third Party Beneficiary Investor Complaints.  On February 17,
    1993, movants, who are investors in production companies and claim to be
    third party beneficiaries of the contracts between Columbia Transmission
    and the production companies, filed a motion seeking to have their status
    as third party beneficiaries recognized and seeking to have their claims
    against Columbia Transmission liquidated separate from the Estimation
    Procedure established to deal with producer claims.  By order dated April
    5, 1993, the Bankruptcy Court lifted the stay in order to allow the New
    Jersey State Court to determine whether plaintiffs enjoyed third party
    beneficiary status in the pending State Court action.  However, the
    Bankruptcy Court with movants' acquiescence, held that movants' claim (to
    the extent that they are established) would be governed by the estimation
    procedure.

             3. Bank of Boston, Trustee v. The Columbia Gas System, Inc.  On
    March 2, 1993, the Trustee for the Indenture under which debentures were
    issued by the Employees Thrift Plan of Columbia Gas System (Plan) filed a
    complaint against the Corporation alleging tortious interference with
    contract and breach of duty.  The Indenture Trustee alleges that the
    Corporation is not acting in accordance with the Plan when it directs the
    Plan Trustee to use sums paid by participating employers to match employee
    contributions and not to pay debt service on the outstanding debentures.
    The Corporation's Answer to the complaint alleging tortious interference
    with contract for failure to pay installments due LESOP debenture holders
    was filed April 2, 1993.  On May 14, 1993, the Corporation filed a motion
    for summary judgment challenging the Bank's standing to bring the action.
    Bank of Boston filed its  brief in opposition to the Corporation's motion
    on June 14, 1993 and the Corporation's reply brief was filed on June 29,
    1993.  Bank of Boston filed an amended adversary complaint on June 30,
    1993.

        B.  Appeals to the United States Court of Appeals for the Third Circuit

             1. Enterprise Energy Corporation, et al., v. United States of
    America, on behalf of its Internal Revenue Service  On June 18, 1991, the
    U.S. District Court for the Southern District of Ohio approved a settlement
    of this class action suit by Appalachian oil and gas producers.  The
    settlement required Columbia Transmission to make two $15 million payments
    into escrow, for distribution to class members as formal contract
    amendments were finalized.  The first $15 million was paid into escrow in
    March 1991.

                Columbia Transmission filed an application with the Bankruptcy
    Court which would permit it to honor the settlement (including authority to
    make the second $15 million payment into escrow in March 1992) but to
    reject the amended contracts.  On December 12, 1991, the Bankruptcy Court
    ruled that distribution from escrow of the first $15 million payment could
    be effected pursuant to the settlement; however, the Bankruptcy Court
    denied Columbia Transmission's request for approval to make the second $15
    million payment scheduled to be made in March 1992.  Further, the
    Bankruptcy Court granted the motion to reject the contracts, as amended,
    pursuant to the Enterprise settlement.

                On October 6, 1992, the District Court affirmed the Bankruptcy
    Court's order denying Columbia Transmission's motion to assume the
    executory settlement contract.  Enterprise Energy Corp.'s request for
    rehearing, reargument and reconsideration of the order denying Columbia
    Transmission's motion to assume the executory settlement contract was
    denied on April 27, 1993.  On May 25, 1993, Enterprise Energy filed a
    notice of appeal to the United States Court of Appeals for the Third
    Circuit from the Bankruptcy Court order denying Columbia Transmission's
    motion to require assumption or rejection of the executory settlement
    contract.  Briefing is complete.  Oral argument was held January 18, 1993.

             2. In re  The Columbia Gas System, Inc. et al.; West Virginia
    State Department of Taxation v. U.S., Nos. 93-7531 and 93-7532.  This is
    the appeal of the District Court's Memorandum Opinion and Order affirming

<PAGE>   10
    ITEM 3.   LEGAL PROCEEDINGS (Continued)

    the Bankruptcy Court's ruling that the property taxes centrally assessed by
    West Virginia as public service business taxes for the "1992 tax year" were
    incurred by Columbia Transmission prepetition and denying Columbia
    Transmission's motion for authorization to pay the taxes.  Briefing has
    been completed and oral argument was heard on March 2, 1994.

             3. The Columbia Gas System, Inc. and Columbia Gas Transmission v.
    U.S. Trustee, No. 93-7609.  On August 30, 1993, the Corporation and
    Columbia Transmission filed an Appeal of the District Court's order
    adopting the Magistrate's Report and Recommendation and granting the U.S.
    Trustee's appeal of the Bankruptcy Court's July 31, 1993 order approving
    certain investment guidelines and the Bankruptcy Court's order denying the
    U.S. Trustee's Motion for Reconsideration of the Bankruptcy Court's July
    31, 1993 order.  On February 10, 1994, the District Court granted a stay
    pending appeal of the August 19, 1993 order which approved the Magistrate's
    Report and Recommendation.

    III. Purchase and Production Matters (Unless otherwise noted, all matters
    are stayed pursuant to Section 362 of the Bankruptcy Code)

         A.  Appalachian Producer Litigation

             1. Enterprise Energy Corp. et al. v. Columbia Gas Transmission
    Corp., C. A. No. C2-85-1209, (U. S. Dist. Ct., S. D.  Ohio, filed July 26,
    1985).  See II B. 1.

             2. Phillips Production Co. v. Columbia Gas Transmission Corp.,
    C.A. No. 89-0269, (U.S. Dist. Ct., W.D. Pa. filed February 7, 1989).  The
    complaint as filed contained six separate counts involving ten gas purchase
    contracts with Columbia Transmission.  Plaintiff's principal claims were
    for additional take-or-pay payments, for retroactive tight sands gas
    pricing, and a challenge to Columbia Transmission's invocation of cost
    recovery clauses in the gas purchase contracts.  All claims except those
    relating to Columbia Transmission's invocation of the cost recovery clause
    were settled and dismissed December 18, 1989, pursuant to agreement of the
    parties.  The cost recovery claim was stayed pending resolution of
    Enterprise Energy suit (discussed above).  Thereafter, Phillips cost
    recovery claim was stayed by Columbia Transmission's filing.

             3. Columbia Gas Transmission Corp. v. Alamco, Inc. et al., C.A.
    No. 88-C-38-2 (Harrison (W.Va) Cir. Ct. filed January 15, 1988).  Under a
    1983 release agreement, Columbia Transmission filed suit against Alamco,
    Inc. (Alamco) contending that Alamco was obligated to sell gas to Columbia
    Transmission at prices and under terms and conditions being generally
    offered by Columbia Transmission at the time purchases were resumed as
    opposed to the conditions of the original contract.  Trial of the state
    court action was interrupted and stayed by Columbia Transmission's petition
    in Bankruptcy filed July 31, 1991.  A parallel suit was filed by Alamco,
    naming the Corporation, Columbia Transmission, Columbia Gas System Service
    Corporation and Commonwealth Gas Pipeline Corporation, alleging antitrust
    violations.  In the opinion of counsel, the antitrust claim was barred by
    the statute of limitations; however on March 13, 1991, Columbia
    Transmission's and Commonwealth Gas Pipeline's motions to dismiss were
    denied without prejudice to Columbia Transmission's right to assert, by
    summary judgment or otherwise, that Alamco's claims are time barred, or
    that Alamco cannot prove the allegations in its complaint.

                In late May 1992, a settlement agreement in principle was
    reached which was approved by the Bankruptcy Court on July 28, 1992.  As a
    result, after the order becomes final, these actions will be dismissed upon
    the earlier of confirmation of a Columbia Transmission plan of
    reorganization or closing of the Columbia Transmission bankruptcy
    proceeding.

         B.  Southwest Producer Litigation (Suits naming Columbia Transmission
    are stayed as to Columbia Transmission; indemnification agreements will be
    effective if the contract providing indemnification is not rejected)

<PAGE>   11
    ITEM 3.   LEGAL PROCEEDINGS (Continued)

             1.  Royalty Owners Litigation: The agreements between Columbia
    Transmission and certain southwest producers effective in 1985 which
    reformed gas purchase contracts have resulted in a number of lawsuits
    against the producers.  Under the agreements, Columbia Transmission has a
    qualified obligation to indemnify the producers in certain instances
    against claims by their royalty owners.

                Certain suits were pending against Amoco Production Company for
    which it was seeking indemnification from Columbia Transmission as of the
    commencement of Columbia Transmission's proceeding in bankruptcy.  In
    November 1993, Columbia Transmission and Amoco entered an agreement,
    subject to Bankruptcy Court approval, terminating the contracts and
    providing that Amoco shall have an allowed unsecured claim for $4.1 million
    for all royalty indemnification and excess royalty claims.

                New Ulm and Fox v. Mobil Oil Corporation, Columbia Gas
    Transmission Corp. and Columbia Gulf Transmission Co.,  C.A.  No. 88-V-655
    (155th Judicial Dist. Ct. of Austin County, TX). New Ulm alleged Columbia
    Transmission incorrectly paid for gas on the basis of Columbia
    Transmission's market-out price rather than the higher price New Ulm
    claimed was available to it under the contracts.

                After the Bankruptcy Court entered an order modifying the
    automatic stay provisions of the Bankruptcy Code, jury trial began on June
    22, 1992, and concluded with a verdict against Columbia Transmission on
    July 2, 1992, in the amount of approximately $5.6 million, including
    interest.  On July 30, 1992, the Court denied Columbia Transmission's
    motion for judgment notwithstanding the jury's verdict and entered judgment
    against Columbia Transmission in such amount for actual damages,
    prejudgment interest and attorneys' fees.  Columbia Transmission's motion
    for new trial was denied on October 12, 1992.  Columbia Transmission has
    perfected an appeal to the First Court of Appeals at Houston, Texas.
    Briefing is complete and oral argument was held on December 7, 1993.

             2. Wagner & Brown v. Columbia Gas Transmission Corp., C.A. No.
    83-15091 (Orleans Parish (La.) Civ. Dist. Ct.).  This suit involves
    Columbia Transmission's alleged breach of a gas purchase and sales
    agreement.  The claims of Wagner & Brown have been settled, and the case
    was dismissed as to Wagner & Brown on March 6, 1986.  The claims of El Paso
    Exploration Co. (now Meridian Oil Production, Inc. (Meridian)), which
    intervened as a plaintiff and asserted all the claims and allegations made
    by Wagner & Brown, including take-or-pay, price differential and specific
    performance, have not been settled.  In September 1990, Meridian served a
    Second Amended Petition in which it alleges damages in excess of $60
    million (and an additional $40 million of interest) as a result of Columbia
    Transmission's failure to meet its take-or-pay and minimum take
    obligations.  The issue of price differential has been settled. A status
    conference was held May 28, 1991, and a hearing on the plaintiff's motion
    for partial summary judgment on Columbia Transmission's legal defenses was
    held June 14, 1991.

                A motion by Meridian for a Bankruptcy Court order lifting the
    automatic stay so as to permit it to prosecute its claims against Columbia
    Transmission was denied.

             3. Koch Industries Inc. v. Columbia Gas Transmission Corp. C.A.
    No. 89-2156 (U.S. Dist. Ct., E.D. La., filed May 12, 1989).  On January 11,
    1991, Columbia Transmission filed an action, Columbia Gas Transmission
    Corp. v. Koch Industries. Inc., C.A. No. 91-0174, (U.S. Dist. Ct., E.D.
    La).  This lawsuit was related to the settlement of an earlier lawsuit
    between the parties.  Columbia Transmission sought an order declaring that
    it is under no obligation to increase its purchase nominations under the
    contracts because of Koch's unasserted right to correct imbalances between
    it and other working interests owners in the acreage dedicated under the
    contract.  Koch filed a complaint seeking a contrary determination.  Koch
    Industries, Inc. v.  Columbia Gas Transmission Corp., C.A. No. 91-0177
    (U.S. Dist. Ct. E.D. La).  The two cases were consolidated.  Judgment in
    favor of Koch Industries, Inc. and against Columbia Transmission was issued
    on April 29, 1991.  Columbia Transmission's motion to alter or amend the
    judgment was denied on June 5, 1991.  On June 19, 1991, Columbia
    Transmission filed a Notice of Appeal to the Fifth Circuit.  On August 20,
    1991, the Clerk of the Court advised

    Columbia Transmission that the case was stayed during the Chapter 11
Bankruptcy proceedings.

             4. Energy Development Corp. v. Columbia Gas Transmission Corp.,
    C.A. No. CV91-0960, (U.S. Dist. Ct., W. D., La., division
    Lafayette/Opelousas, filed May 13, 1991).  Energy Development Corporation
    alleges that Columbia Transmission breached the take-or-pay, minimum daily
    quantity and inequitable withdrawal provisions of the gas purchase contract
    between Energy Development Corporation and Columbia Transmission.

    IV.  Corporate Matters

             1. The East Lynn Condemnation - United States v. 16.286.08 Acres
    et al., C.A. No. 77-3324H (U. S. Dist. Ct., S.D. W.Va.  filed December 26,
    1976).  The United States Corps of Engineers condemned certain fee lands in
    Wayne County, West Virginia.  On December 7, 1990, a United States District
    Judge issued an order which adjudicates the amount of just compensation
    Columbia Natural Resources was entitled to receive for the minerals taken,
    including interest on the award through October 31, 1990, at $44,830,148.
    In October 1991, checks totalling $52,254,883 were issued to Columbia
    Transmission (holder of letter to the property when the condemnation
    proceeding commenced), Columbia Natural Resources (current owner) and the
    attorneys in the condemnation proceeding.  To allow immediate deposit, the
    checks were endorsed to Columbia Transmission. Columbia Natural Resources
    and Columbia Transmission believe that a constructive trust in favor of
    Columbia Natural Resources, the real party in interest, was created;
    however, this view may be subject to challenge in Columbia Transmission's
    bankruptcy proceeding.

    V.   Regulatory Matters

         A.  Take-or-Pay and Contract Reformation Costs Billed by Pipeline
             Suppliers

             1. Columbia Gas Transmission Corp., FERC Dkt. No. RP91-41, appeals
    pending sub nom., Baltimore Gas & Electric Co. v.  FERC, C.A. No. 88-1779
    U.S. Ct. of App., D.C. Cir.)  On February 3, 1992, FERC denied requests for
    rehearing of orders accepting Columbia Transmission's Order No. 528
    flowthrough filings, except to the extent that customers may challenge
    Columbia Transmission's prudence for actions after April 1, 1987, to the
    extent that it contributed to these upstream pipeline charges.  On March
    19, 1993 the FERC issued an order denying requests for rehearing and
    permitting Columbia Transmission to flow through upstream pipeline Order
    No. 528 costs.  On December 30, 1993, the FERC issued an order denying
    Cincinnati Gas & Electric Company's request for rehearing of the March 19,
    1993 order, reaffirmed the February 3, 1992 and March 19, 1993 orders in
    all respects, and indicated that no further rehearing requests would be
    entertained.  The Court issued a procedural order in the joint appeals,
    leading to oral argument on May 10, 1994.

             2. AGD v. FERC, No. 88-1385 (U.S. Ct. of App., D.C. Cir.).  On
    December 28, 1989, the U.S. Court of Appeals for the District of Columbia
    Circuit ruled that the deficiency-based direct billing of Order No. 500
    costs approved by the FERC in Tennessee Gas Pipeline Co., No. RP86-119, is
    unlawful retroactive ratemaking and violates the filed rate doctrine.  On
    October 9, 1990, the U.S. Supreme Court denied certiorari in AGD.
    Accordingly, the FERC issued its order on remand on November 1, 1990 (Order
    No. 528).

                The FERC has approved Order No. 528 settlements for some of
    Columbia Transmission's pipeline suppliers.  However, there are remaining
    unresolved direct upstream pipeline supplier Order No. 528 proceedings.

                The Order No. 528 filings and settlements to date have reduced
    Columbia Transmission's Order No. 528 liability to upstream pipelines
    significantly.  Columbia Transmission's customers continue to challenge its
    right to recover any of these amounts.

         B.  Direct Billing of Past Period Production and Production-Related
             Costs





                                       12

    ITEM 3.   LEGAL PROCEEDINGS (Continued)

             1. Columbia Gas Transmission Corp. v. FERC., C.A. No. 88-1701
    (U.S. Ct. of App., D.C. Circuit).  On February 9, 1990, the Court issued
    its opinion finding that the FERC's orders authorizing five of Columbia
    Transmission's upstream pipeline suppliers to directly bill past period
    production related costs (Order Nos. 94 and 473) to customers allocated
    based upon past period purchases violates the filed rate doctrine and the
    rule against retroactive ratemaking.  Therefore, the Court struck the
    orders authorizing direct billing and remanded the issue to the FERC for
    further proceedings.  On October 9, 1990, the U.S.  Supreme Court denied
    certiorari.

                Columbia Transmission reached settlements with Panhandle,
    Trunkline, Texas Eastern and Texas Gas, which provided for full
    refunds of Order No. 94 direct billings with rebillings to Columbia
    Transmission of lesser amounts.  These settlements would reduce Columbia
    Transmission's Order No. 94 direct billing liability to these pipelines
    from $29 million to $17 million exclusive of interest.  Columbia
    Transmission's customers have objected to those settlements because they
    contemplate Columbia Transmission's recovery of these rebilled amounts
    from its customers.  On February 10, 1993, the FERC approved Columbia
    Transmission's Order 94 settlement with four pipeline suppliers, which
    settlements authorized Columbia Transmission to recover the rebilled
    payments to its' customers.

                On October 28, 1993, Transco and Columbia Transmission filed a
    letter with the FERC indicating that the remaining issues have been
    resolved, and that they agreed on a refund to Columbia Transmission of $1.4
    million.  The FERC is treating this as a settlement offer.

                On January 12, 1994, the FERC issued an order on rehearing in
    which it reversed its earlier conclusions and rejected the Order No. 94
    settlements with Panhandle, Trunkline, Texas Eastern and Texas Gas.  FERC
    now holds that Columbia Transmission's 1985 PGA settlement essentially bars
    recovery of any of the rejected costs.  The January 12, 1994, order
    required Panhandle, Texas Eastern and Texas Gas to refund all Order No. 94
    costs, but absolved them of responsibility for paying interest.  On
    February 14, 1994, Columbia Transmission and the upstream pipelines
    requested rehearing of the January 12 orders.  The pipelines have received
    an extension of time to make refunds until after the FERC rules on
    rehearing.  Columbia Transmission has asked the FERC to hold the Transco
    settlement in abeyance until after the FERC rules on rehearing.  Transco
    has opposed this request.

         C.  WACOG Recovery.

             1. Columbia Gas Transmission Corp., FERC Dkt. No. RP91-206.  On
    August 1, 1991, Columbia Transmission filed for a 12- month, 20 cent
    surcharge to its commodity rate to recover certain pre-April 1, 1985,
    supplier costs which it is entitled to recover, in accordance with the
    terms of its 1985 Purchased Gas Adjustment settlement, to the extent that
    its annual weighted average cost of gas (WACOG) compares favorably with the
    WACOGs of competing pipelines.  On August 30, 1991, FERC rejected such
    filing, without prejudice, finding that Columbia Transmission's calculation
    of its WACOG was inconsistent with the 1985 settlement.  On May 22, 1992,
    the FERC denied Columbia Transmission's request for rehearing.  Columbia
    Transmission has filed a petition for review of these orders.  The matter
    has been briefed by the parties and oral argument was held on October 22,
    1993.  On January 3, 1994, Columbia Transmission filed an offer of
    settlement in Docket Nos. RP93-161 and RP94-1 (see C.3. below) which
    provides that, upon final approval of the settlement, Columbia Transmission
    will dismiss its appeal.

             2. Columbia Gas Transmission Corp., FERC Dkt. No. RP92-215.  On
    July 31, 1992, Columbia Transmission proposed an 8 cents per Dekatherm
    surcharge for the 12 months commencing September 1, 1992.  On August 31,
    1992, the FERC accepted Columbia Transmission's filing subject to
    suspension, refund and a technical conference.  After such technical
    conference and statements of position by the parties, the FERC rejected the
    WACOG filing on January 21, 1993 and ordered Columbia Transmission to
    refund all WACOG charges which it previously collected.  On November 26,
    1993, the FERC denied Columbia Transmission's request for rehearing of the
    January 21, 1993, order.  Columbia Transmission has filed a petition for
    review of these orders with the

<PAGE>   14
    ITEM 3.   LEGAL PROCEEDINGS (Continued)

    United States Court of Appeals for the D.C. Circuit.  On January 3, 1994,
    Columbia filed an offer of settlement in Docket Nos.  RP93-161 and RP94-1
    (see C.3. below) which provides that, upon final approval of the
    settlement, Columbia Transmission will dismiss its appeal of the orders.

             3. Columbia Gas Transmission Corp., Dkt. Nos. RP93-161 and RP94-1.
    These filings proposed a WACOG surcharge for the 1993-94 period, the last
    year Columbia Transmission is eligible to file such surcharge.  The filing
    in RP93-161 proposed to collect a 28 cents per Dth surcharge for sales
    customers for the months of September and October 1993.  The filing in
    RP94-1 proposed to collect a surcharge of 7.22 cents per Dth for most firm
    transportation customers from November 1, 1993 when Columbia Transmission
    implemented Order 636, through October 31, 1994.  On January 3, 1994,
    Columbia Transmission filed a settlement which is unopposed to obtain all
    WACOG surcharges collected during September-December, 1993 and collect a
    WACOG surcharge of 3.8c. per Dth during January-October, 1994.  If Columbia
    Transmission's WACOG surcharge revenues exceed $42.8 million, it will
    refund 90% of the excess to customers and retain the remaining 10%.  FERC
    approved the settlement on February 28, 1994.

    VI.  Other

             A. Canada Southern Petroleum Ltd. v. Columbia Gas Development of
    Canada Ltd. et al., (C.A. No. 9001-03466, Court of Queen's Bench, Alberta,
    Canada, filed March 7, 1990).  The plaintiff asserts, among other things,
    that the defendant working interest owners, including Columbia Gas
    Development of Canada Ltd. (Columbia Canada) and various Amoco affiliates,
    breached an alleged fiduciary duty to ensure the earliest feasible
    marketing of gas from the Kotaneelee field (Yukon Territory, Canada).  The
    plaintiff seeks, among other remedies, the return of the defendants'
    interests in the Kotaneelee field to the plaintiff, a declaration that such
    interests are held in trust for the plaintiff, and an order requiring the
    defendants to promptly market Kotaneelee gas or assessing damages.

                The judge granted the application of Allied Signal, Inc., Home
    Oil Company and Kern County Land Company to relieve them of the requirement
    to participate in the proceedings. An appeal of the order by Amoco is
    pending.

                Examination for discovery is still proceeding in the referenced
    actions.  Columbia Canada has had a second round of discovery of its
    witnesses and has made undertakings to provide additional information which
    it is in the process of preparing.  Amoco has not yet fulfilled the
    undertakings from its first round of discoveries.  Upon it doing so, it is
    reasonable to suppose that further discoveries of Amoco will be required by
    Canada Southern.

                None of the defendants has yet conducted any discovery of
    Canada Southern nor of one another.  On the present schedule, it is likely
    that this discovery process will continue well into 1994.

                In early 1993, Canada Southern filed a motion to amend their
    statement of claim to seek an accounting of the amount of operation costs
    properly recoverable by the working interest holders including Columbia
    Canada.  Columbia has not consented to the amendment and contends that any
    amounts accrued since the initial statement of claim in 1988 should be
    barred and more basically, that litigation is inappropriate prior to an
    audit.

                Note:  Columbia Canada was sold to Anderson Exploration Ltd.
    effective December 31, 1991, and the company name subsequently changed to
    Anderson Oil & Gas, Inc.  Pursuant to an Indemnification Agreement re
    Kotaneelee Litigation, Columbia agreed to indemnify and hold Anderson
    harmless from losses due to this litigation.  An escrow account in the
    amount of approximately $30,000,000 (Cdn) was established as partial
    security for the indemnification obligation.  Upon emerging from
    bankruptcy, an additional deposit to the Escrow Account of $25,000,000
    (Cdn) will be required in cash or by letter of credit.

    ITEM 3.   LEGAL PROCEEDINGS (Continued)

             B. Minerals Management Service (MMS) has demanded that Columbia
    Gas Development Corporation (Columbia Development) pay additional royalties
    for the period October 1, 1983 to December 31, 1985, claiming the prices
    received by Columbia Development from its affiliate under non-arm's-length
    contracts were less than the prices received for like-quality gas under
    comparable arms-length contracts in the field.  A complaint was filed by
    Columbia Development in U.S. District Court in Dallas on October 23, 1992,
    (Case No. 3:92-CV2199-T), claiming that the six-year statute of limitation
    applicable to the claim has expired and a protective administrative appeal
    was filed with the MMS on October 27, 1992.  A decision was rendered August
    27, 1993, by the Northern District of Texas District Court in favor of the
    government on the statute of limitations issue, reasoning that the MMS
    order to pay is not "an action for money damages" under the language of the
    statute and further granted the government's motion to dismiss in part on
    the basis of the doctrine of exhaustion of administrative remedies.
    Columbia Development has appealed the District Court decision to the Fifth
    Circuit Court of Appeals.  Columbia Development's initial brief was filed
    on January 10, 1994.  In another case, the 10th Circuit Court of Appeals
    ruled in favor of the government on the statue of limitations issue on the
    grounds that the six-year statute of limitations is tolled until such time
    as the government could reasonably have known about all facts material to
    its right of action.

                In addition, the MMS audited Columbia Development for the
    period January 1, 1986, through December 31, 1990, and has made a similar
    but unquantified claim.  Columbia Development has appealed this claim to
    the Interior Board of Land Appeals and has obtained the MMS's pricing data
    and analyzed it using comparable pricing from surrounding OCS blocks to
    determine probable liability.  Meetings with the MMS to eliminate less
    controversial claims (third party sales and sales at MLP) and to present
    the comparable pricing analysis have been held.  MMS is reviewing the
    information presented.

    VII.  Environmental

             A. Commonwealth of Kentucky Natural Resources and Environmental
    Protection Cabinet, Department for Environmental Protection.  On January
    22, 1992, Columbia Transmission received Notices of Violation (NOV) from
    the Commonwealth of Kentucky, Natural Resources and Environmental Cabinet,
    Department of Environmental Protection (KyDEP) with respect to ten
    compressor station sites in the Commonwealth of Kentucky.  These notices
    generally cite the release or disposal of waste materials or hazardous
    substances, including but not limited to polychlorinated-biphenyls (PCBs).
    It appears from a letter dated January 13, 1992, from the Natural Resources
    Environmental Protection Cabinet, Department of Law, that the violations
    have been asserted for the purposes of establishing the Cabinet's
    prepetition claims against Columbia Transmission.

                The alleged violations provide for fines and penalties that
    apply separately for each violation and each day of noncompliance which, in
    the aggregate, are significant.  Columbia Transmission's prior experiences,
    however, as well as those of other companies in the industry, have
    demonstrated that such fines and penalties have not been assessed at the
    maximum rate when the company is cooperating with governmental agencies and
    authorities in remediation activities.  Columbia Transmission intends to
    continue to work with the KyDEP in negotiating a consent decree approving
    prior remediation activity and a prospective remediation plan.

             B.  In the Matter of Columbia Gas Transmission Corp., (Region
    III).  Columbia Transmission was subpoenaed to supply information under the
    authority of the Toxic Substance Control Act (TSCA), the Resource
    Conservation Recovery Act and the Comprehensive Environmental Response
    Compensation and Liability Act of 1980.  Documents were accumulated and
    delivered in June and July and conferences with personnel of the
    Environmental Protection Agency Region III have been held.  Columbia
    Transmission is continuing to provide documents and information to
    Environmental Protection Agency Region III and has begun negotiation of a
    possible consent decree under the TSCA approving prior remediation activity
    and prospective remediation plans developed by Columbia Transmission.
    Fines or penalties may also be included.

    ITEM 3.   LEGAL PROCEEDINGS (Continued)

             C.   Portsmouth Redevelopment and Housing Authority and
    Commonwealth Gas Services, Inc. (Commonwealth) v. BMI Apartment Associates,
    C.A. No. 2:93CV242, (U.S. Dist. Ct. E.D. Va., filed March 25, 1993.)  A gas
    manufacturing plant had been operated in Portsmouth, Virginia by Portsmouth
    Gas Co on a site that was subsequently sold by Portsmouth Gas Co. to the
    Portsmouth Redevelopment and Housing Authority, which removed equipment and
    sold the property to developers of apartment complexes and single-family
    homes.  Portsmouth Gas Co. was later acquired by Commonwealth.  On February
    10, 1993, without admitting or conceding responsibility for the site,
    Commonwealth provided notice of site contamination to the United States
    Environmental Protection Agency.  On March 25, 1993, Commonwealth and the
    Portsmouth Housing and Redevelopment Authority filed a cost recovery action
    in federal court under the Comprehensive Environmental Response
    Compensation and Liability Act of 1980 against the current and past owners
    of a former manufactured gas plant site and sought a court order to obtain
    access to the site for health risk testing.   BMI Apartment Associates
    (BMI), the owners of apartments on the site objected to the request for
    access and filed a "citizens' suit" under the Resource Conservation and
    Recovery Act as a counterclaim and cross-claim.  On June 14, 1993, the
    United States District Court granted Commonwealth and the Portsmouth
    Redevelopment and Housing Authority access to the site to perform the
    health risk testing and testing on-site was completed June 24, 1993.  On
    July 28, 1993, the Court dismissed the counterclaims of BMI that were drawn
    on RCRA and loss of contribution protection under CERCLA.  The remaining
    liabilities, damages and allocations are similar for both defendants and
    plaintiffs.  The Health Risk Assessment Report was provided to all parties
    on August 27, 1993.  It finds "no imminent risk to public health."  Further
    investigation will be conducted without relocating residents.  In
    mid-September, 1993, the judge granted an eight month stay of all legal
    proceedings to permit Commonwealth to conduct full site investigation and
    provide the opportunity for the parties to discuss settlement.  The
    workplan was completed and work began on November 1, 1993.  Emergency
    permits for waste handling from the City of Portsmouth were obtained to
    facilitate the investigation.  Residents and nearby homeowners were
    notified of the work.  Commonwealth met with the voluntary Remediation
    Group of VaDEQ.  A draft consent agreement delineating the VaDEQ's
    supervisory responsibility for site work is being developed.  On February
    14, 1994, a Magistrate was appointed to facilitate settlement discussions.

             D.   Commonwealth Gas Services/Virginia Department of
    Environmental Quality.  On February 9, 1993, Commonwealth reported to the
    Virginia Department of Environmental Quality's (VaDEQ) State Water Control
    Board that an oily substance was seeping through a retaining wall at a
    former manufactured gas plant site at Petersburg, Virginia.  On April 5,
    1993 Commonwealth received a request from the State Water Control Board to
    investigate the seep and submit a report to the Board.  Commonwealth has
    retained a consultant to investigate the seep and prepare the report.  Site
    assessment was submitted to the VaDEQ on July 20, 1993.  That report
    recommends removal of contents of a tank behind the retaining wall.  The
    report also disclosed an additional seep of materials from the creek
    upstream of the retaining wall area.  On July 27, 1993, VaDEQ accepted
    Commonwealth's recommendations on the two seeps.  Commonwealth is
    proceeding to implement those recommendations over the next six months.  On
    November 1, 1993, a report on the creek bank seep was sent to VaDEQ.  It
    notes fairly widespread groundwater and soil contamination, as well as
    identifying the source of the creek bank seep.  On December 10, 1993,
    Commonwealth met with the VaDEQ regarding the recently filed report.
    Commonwealth consultants are developing a workplan to address the
    contamination noted in the report.  Commonwealth is now dealing with VaDEQ
    remediation group and is in the process of developing a draft memorandum of
    understanding delineating the course of action to be taken.

             E.   In Re Columbia Gas Transmission (Region V).  On January 28,
    1994, Columbia Transmission received from USEPA Region V an Information
    Request pursuant to the Resource Conservation and Recovery Act (RCRA).  The
    Agency requests Columbia Transmission to submit information and knowledge
    relating to its generation and management of natural gas pipeline
    condensate, used engine oil and similar liquids in the state of Ohio.
    Transmission is in the process of analyzing the information requested and
    will be discussing this Information Request with Region V.

                               BANKRUPTCY MATTERS

    On July 31, 1991, The Columbia Gas System, Inc. (Corporation) and its
    wholly-owned subsidiary, Columbia Gas Transmission Corporation (Columbia
    Transmission), filed separate petitions seeking protection under Chapter 11
    of the Federal Bankruptcy Code. Both the Corporation and Columbia
    Transmission were granted debtor-in-possession status under the Bankruptcy
    Code, allowing them to continue normal business operations subject to the
    jurisdiction of the United States Bankruptcy Court for the District of
    Delaware (Bankruptcy Court).

    Columbia Transmission's Plan of Reorganization
    The Corporation's and Columbia Transmission's discussions with the
    Official Committee of Unsecured Creditors of Columbia Transmission
    (Columbia Transmission Creditors' Committee) to negotiate a reorganization
    plan for Columbia Transmission and expedite emergence from Chapter 11
    proceedings had been largely unsuccessful.  Therefore, on January 18,
    1994, Columbia Transmission filed, with the Corporation as cosponsor, a
    reorganization plan (plan) and a disclosure statement, for consideration
    by its creditors and other interested parties.  The plan, which management
    believes is fair and equitable, proposes to pay 100 percent for all
    priority, administrative and secured claims and offers various classes of
    general unsecured creditors, including producers whose gas contracts were
    rejected by Columbia Transmission, between 80 and 100 percent of Columbia
    Transmission's estimates of their allowable claims.  The $3.3 billion
    total distribution proposed in Columbia Transmission's plan is based on an
    estimated value for Columbia Transmission of $3.1 billion and includes
    significant financial contributions by the Corporation.  The plan is
    premised on a proposed omnibus settlement whereby the Corporation would
    settle the Intercompany Complaint and facilitate Columbia Transmission's
    reorganization by (i) accepting the value of the Corporation's secured
    claims against Columbia Transmission in the form of secured debt and
    equity securities of Columbia Transmission, and (ii) ensuring the cash (or
    at the option of the Corporation cash and $100 million market value of the
    Corporation's common stock) necessary to bring the aggregate distribution
    to $3.3 billion.  Creditors, other than the Corporation, would share in
    distributions of over $1.2 billion in cash.  In addition, the Corporation
    would consent to the reorganized Columbia Transmission's assumption of
    responsibility for public environmental enforcement agency claims so that
    the recoveries of the other creditors would not, with minor exceptions, be
    diminished by the environmental liabilities of Columbia Transmission's
    estate.

    The plan provides that Columbia Transmission will remain a wholly-owned
    subsidiary of the Corporation, will continue to offer an array of
    competitive transportation and storage services, and will retain ownership
    of its 18,800-mile pipeline network and related facilities.

    Columbia Transmission's proposed business solution will offer to producers,
    whose gas supply contracts were rejected or who have prepetition claims
    under those contracts, individual, specific settlements of the producers'
    claims that are based upon uniform assumptions and principles and which, in
    the view of Columbia Transmission's management, are fair and reasonable
    settlement values.  These specific settlement proposals are being developed

    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    and will be filed as an adjunct to the plan.  Columbia Transmission
    estimates that aggregate distributions to producers under the plan would
    come to approximately $900 million.

    In general, the plan provides for immediate cash payment in full to all
    priority claims, all secured claims held other than by the Corporation,
    trust fund claims, administrative expenses and unsecured claims of $50,000
    or less.  The Corporation's secured claims will be satisfied in full with
    new secured debt and equity securities to be issued by the reorganized
    Columbia Transmission.  Unsecured claims between $50,000 and $250,000 would
    receive 95 percent of their allowed claims in cash.   All other unsecured
    claims, including the Corporation's unsecured debt and producer contract
    rejection claims, would receive between 80 and 100 percent of their allowed
    claims based on current projections.  With respect to some of the classes
    of creditors, the treatment described above depends on the acceptance of
    the plan by the relevant class.  At this time, no creditors have agreed to
    any of the proposed plan's provisions, and the ultimate confirmed plan of
    reorganization could be materially different from this initial filing.

    Although Columbia Transmission's plan utilizes June 30, 1994, as an assumed
    date of emergence from bankruptcy, the actual date of emergence will depend
    on the time required to complete the bankruptcy process and obtain
    necessary creditor, judicial and regulatory approvals.  As part of its
    filing with the Bankruptcy Court, Columbia Transmission requested that the
    court defer scheduling required proceedings on the plan and related
    disclosure statement in order to permit discussions of the plan, including
    the settlements proposed therein, with Columbia Transmission's creditors,
    official committees and other interested parties.

    Under bankruptcy procedures, after Columbia Transmission's disclosure
    statement has been approved by the Bankruptcy Court, the disclosure
    statement and the reorganization plan will be sent to the company's
    creditors for voting.

    The Corporation intends to file a plan for its reorganization which will be
    consistent with the financial aspects and structure of Columbia
    Transmission's proposed plan of reorganization.  Both plans will be subject
    to a lengthy review and approval process, including SEC approval, and
    obtaining adequate financing.

    Implementation of Columbia Transmission's plan, and the levels and timing
    of distributions to its creditors, are subject to a number of risk factors
    which could materially impact their outcome.  The plan sets forth numerous
    conditions to its confirmation and consummation. The failure to satisfy
    these conditions in accordance with the terms of the plan would have a
    material adverse effect on the outcome of Columbia Transmission's
    bankruptcy and on the Corporation. These conditions include, among others,
    the confirmation of a reorganization plan for the Corporation, the receipt
    of necessary approvals for the implementation of Columbia Transmission's
    plan and the recovery of regulatory and tax benefits which are fundamental
    to the plan's viability.  Both companies anticipate emerging from
    bankruptcy at the same time.  The provisions of the reorganization plans of
    either Columbia Transmission or the Corporation that are ultimately
    implemented could be materially different from this initial filing for
    Columbia Transmission and have a material adverse effect on the Corporation
    and its subsidiaries and on the rights of shareholders and holders of debt
    and other obligations.

    Events Leading to Bankruptcy Filings
    Columbia Transmission's Chapter 11 filing was precipitated by a combination
    of events that adversely affected its physical operations and financial
    viability.  Most notable were federal legislative and regulatory actions,
    instituted years after Columbia Transmission's gas purchase contracts were
    signed, that significantly impacted Columbia Transmission's ability to sell
    the gas it had contracted to buy and to recover its costs from its
    customers.  These problems were exacerbated by record-setting warm weather
    in 1990 and 1991, which caused spot market prices for gas to plunge and
    created excess transportation capacity, thus making an unexpected and
    persistent oversupply of bargain-priced gas available to Columbia
    Transmission's customers.  As a result, Columbia Transmission's ability to
    market its gas was severely undercut, substantially reducing both sales
    volumes and revenues.

<PAGE>   21
    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    After completing studies, in early June 1991, that revealed the magnitude
    of Columbia Transmission's gas supply problems, the Corporation announced
    on June 19, 1991, that: (i) it anticipated that a substantial portion of
    Columbia Transmission's exposure on above-market priced gas purchase
    contracts would be charged to income in the second quarter; (ii) Columbia
    Transmission was launching a comprehensive effort to renegotiate or
    terminate all of its above-market gas purchase contracts under a program
    which contemplated offering producers up to $600 million of Columbia
    Transmission's obligations as compensation for restructuring their
    contracts; (iii) the Corporation was suspending the dividend on its common
    stock; and (iv) corporate officers were meeting with bank lenders that day
    seeking to reestablish the Corporation's credit facilities on revised terms
    in view of Columbia Transmission's financial difficulties.  In addition,
    Columbia Transmission's financial problems were exacerbated when the West
    Virginia Supreme Court ordered the posting of a $10 million bond by July
    29, 1991, in order to stay the execution of a $29.5 million judgment in a
    lease dispute which was subsequently reversed.

    As of July 31, 1991, the Corporation was in default on $83.5 million of
    short-term obligations and the negotiations with banks and producers had
    met with only limited success.  As a result, on July 31, 1991, the
    Corporation and Columbia Transmission filed for protection under Chapter 11
    of the Federal Bankruptcy Code in the Bankruptcy Court.  A discussion of
    the proceedings under Chapter 11 protection is included in Note 2 of Notes
    to Consolidated Financial Statements.

    In contrast to the situation of many other Chapter 11 debtors,
    reorganization of Columbia Transmission has not been hampered by
    unprofitable or marginal business operations.  Rather, in Columbia
    Transmission's case the achievement of the Chapter 11 objective of
    reorganization has been impacted by the enormity and complexity of the
    disputed and contingent claims filed against it by unaffiliated creditors
    and by attempts on behalf of those creditors to obtain recoveries on such
    claims from the assets of the Corporation's estate.  In addition, Columbia
    Transmission's status as a regulated gas transmission company under the
    Natural Gas Act (NGA) and its resulting obligations has brought into the
    bankruptcy forum creditors' rights issues which are complicated by public
    law issues arising under the NGA.

    Bankruptcy Issues
    On March 19, 1992, the Columbia Transmission Creditors' Committee filed a
    complaint (Intercompany Complaint) with the Bankruptcy Court alleging that
    the $1.7 billion of Columbia Transmission's secured and unsecured debt
    securities held by the Corporation should be recharacterized as capital
    contributions (rather than loans) and equitably subordinated to the claims
    of Columbia Transmission's other creditors.  The Intercompany Complaint
    also challenges interest and dividend payments made by Columbia
    Transmission to the Corporation of approximately $500 million for the
    period from 1988 to the petition date and the 1990 property transfer from
    Columbia Transmission to Columbia Natural Resources, Inc. (CNR) as an
    alleged fraudulent transfer.  Based on the SEC's standardized measurement
    procedures, CNR's properties had a reserve value of approximately $387
    million as of December 31, 1993, a significant portion of which is
    attributable to the transfer from Columbia Transmission.  In May 1992,
    Columbia Transmission Creditors' Committee filed with the U.S. District
    Court a motion for a jury trial and to move the Intercompany Complaint from
    the Bankruptcy Court to the U.S. District Court.  This motion was denied
    and subsequently appealed to the Third Circuit Court of Appeals (Third
    Circuit).  In June 1992, the Corporation filed a motion with the Bankruptcy
    Court seeking dismissal of, or summary judgment on, principal portions of
    the Intercompany Complaint. On August 20, 1993, the Third Circuit denied
    Columbia Transmission Creditors' Committee's appeal, allowing the
    Bankruptcy Court to consider the merits of the Intercompany Complaint and
    act upon the Corporation's June 1992 motion for summary judgment.  The
    Bankruptcy Court has not acted on the Corporation's motion for summary
    judgment, but tentatively scheduled a trial on the Intercompany Complaint
    to begin June 13, 1994.  Management believes that the Intercompany
    Complaint is without merit; however, the ultimate outcome of these issues
    is uncertain at this stage of the proceedings.

    Discussions with Columbia Transmission's creditors in an attempt to
    establish the value of the estate and to resolve

    the matters raised in the Intercompany Complaint are ongoing.  Since the
    standing and value of the Corporation's debt investment in Columbia
    Transmission is crucial to the determination of the value of the
    Corporation's estate, the Corporation's reorganization could be affected by
    the ultimate outcome of the Intercompany Complaint.

    At December 31, 1993, the Corporation's investment in Columbia Transmission
    is as follows:

    The Corporation has claims against Columbia Transmission's estate for money
    it borrowed which are secured by substantially all of Columbia
    Transmission's assets, including cash.  This indebtedness bears interest at
    rates significantly higher than those earned by Columbia Transmission on
    its excess cash because of bankruptcy imposed limitations on Columbia
    Transmission's temporary investments and the current level of interest
    rates.  As a result, the growth in Columbia Transmission's secured interest
    obligations has exceeded its interest earnings on its cash available for
    debt service by an amount projected to exceed $300 million by the end of
    June 1994.

    The Internal Revenue Service (IRS) filed identical claims of $553.7 million
    against both debtor companies and the consolidated Columbia Gas System for
    tax deficiencies, interest and penalties for the years 1983-1990.
    Negotiations with IRS representatives have resulted in a settlement on all
    of the issues included in the IRS claims.  This settlement has been
    documented in a written closing agreement and filed with the Joint
    Committee on Taxation of the U.S. Congress for formal approval. The IRS
    settlement also requires Bankruptcy Court approval.  Recording the IRS
    settlement reduced 1993 net income by $44.3 million.

    Columbia Transmission has recorded liabilities of approximately $1.2
    billion to reflect the estimated effects of its above- market producer
    contracts and estimated supplier obligations associated with pricing
    disputes and take-or-pay obligations for historical periods.  With
    Bankruptcy Court approval, Columbia Transmission rejected more than 4,800
    above-market gas purchase contracts with producers.  The producers whose
    gas purchase contracts were rejected filed claims for damages that, after
    being adjusted for duplicative and other erroneous claims, are in excess of
    $13 billion.  The Bankruptcy Court approved the appointment of a claims
    mediator in 1992 to implement a claims estimation procedure related to the
    rejected above-market producer contracts and other producer claims.  The
    mediator held hearings on generic issues and various estimation
    methodologies and discovery matters during 1993.  Columbia Transmission
    anticipates that the mediator may issue recommended determinations during
    the second quarter of 1994 which, under the Bankruptcy Court-approved
    estimation procedure, are expected to provide the basis for a recalculation
    of producer contract rejection claims.  In Columbia Transmission's
    judgment, the positions taken by all producers before the claims mediator
    and the evidence presented demonstrate that the total level of allowable
    contract rejection claims, generically determined, will not exceed 1/10th
    of the $13 billion asserted in the claims as filed and is likely to be
    between $600 million and $950 million.  The acceptance of certain positions
    advanced by Columbia Transmission on the evidence of record, as well as
    Columbia Transmission's as yet unheard defenses, could decrease
    substantially this range of possible aggregate outcomes.  Resolution of the
    contract-specific issues

    not yet presented could increase or decrease individual claims materially
    but should not significantly alter the range of possible aggregate
    outcomes.

    The resolution of these issues can significantly influence future reported
    financial results.  Accounting standards require that as claim amounts are
    allowed by the Bankruptcy Court, the full amount of the allowed claim must
    be recorded.  This could result in liabilities being recorded which bear
    little relationship to the amounts ultimately required to be paid in
    settlement of those claims and could conceivably exceed the Corporation's
    total investment in Columbia Transmission.  Any such distortion would not
    be corrected until final plans of reorganization are approved for the
    Corporation and Columbia Transmission.

    At a hearing on February 23, 1994, the Bankruptcy Court granted the
    Columbia Transmission Creditors' Committee's motion for the establishment
    of a data room that will make business information on Columbia Transmission
    available to third parties who may be interested in the company.  In
    granting the motion, the Bankruptcy Court instructed the parties to jointly
    develop proposed data room procedures which should provide for a
    substantial entrance fee, exclude Columbia Transmission's future business
    plans and projections and establish strong confidentiality protections.
    The Bankruptcy Court also instructed that such procedures should be filed
    with the Bankruptcy Court by March 11, 1994, for a hearing on March 15,
    1994.  Columbia Transmission is working toward the expeditious development
    and conclusion of the data room process in order to minimize any potential
    delays to its reorganization efforts.  The Corporation has stated that its
    Columbia Transmission subsidiary is not for sale but that if a credible,
    bona fide third party offer is made for that company, it would be given
    appropriate consideration.

                              Other Related Issues

    Corporation's Objection to Claims
    In 1993, the Bankruptcy Court granted the Corporation's request to expunge
    over 7,100 proofs of claim filed against the Corporation.  As a result,
    less than 500 filed claims against the Corporation currently remain to be
    resolved.

    Leveraged Employee Stock Ownership Plan
    On May 31, 1992, the debt service payment on debentures issued under the
    Leveraged Employee Stock Ownership Plan (LESOP) portion of the Columbia's
    Employees' Thrift Plan (Thrift Plan) was not made and no further debt
    service payments are likely to be made until the Corporation emerges from
    bankruptcy.  Under the terms of the Corporation's guarantee of the
    debentures, the LESOP debenture holders will become creditors of the
    Corporation, subordinated to holders of the debentures and medium-term
    notes issued by the Corporation.  Management has concluded that it is more
    equitable and may be economically preferable to pay all creditors at the
    same time in accordance with consummation of the Corporation's plan of
    reorganization.

    The Trustee for the Indenture under which the debentures were issued by the
    Thrift Plan filed a complaint against the Corporation on March 2, 1993,
    alleging tortious interference with contract for failure to pay
    installments due LESOP debenture holders.  On April 2, 1993, the
    Corporation filed an answer to the complaint and, on May 14, 1993, filed a
    motion in the Bankruptcy Court for summary judgment to dismiss this action
    which is still pending.

    Security Holder Litigation
    After the announcement on June 19, 1991, regarding the Corporation's
    probable charge to second quarter earnings and the suspension of its
    dividend, 17 complaints including purported class actions were filed
    against the Corporation and its directors and certain officers of the
    debtor companies in the U.S. District Court of Delaware.  The actions,
    which generally allege violations of certain antifraud provisions of the
    Securities Act of 1933 and the Securities Exchange Act of 1934, have been
    consolidated.  In addition, three derivative actions were filed in the
    Court of Chancery in and for New Castle County (Delaware) alleging that
    directors breached their fiduciary duties.





                                       23
<PAGE>   24
    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    These suits have been stayed by either the Bankruptcy Court filing or by
    stipulation of the parties.  While the Corporation believes that it has
    meritorious defenses to these actions, the outcome is uncertain at this
    time.

    Customer Refunds
    In July 1993, the U.S. Court of Appeals for the Third Circuit overturned
    most of a U.S. District Court ruling and affirmed an earlier Bankruptcy
    Court decision that refunds Columbia Transmission received from upstream
    pipelines, as well as the Gas Research Institute (GRI) surcharge payments
    it collected from customers, are held in trust, by Columbia Transmission,
    for those customers and the GRI and are not part of Columbia Transmission's
    estate.  In August 1993, the Third Circuit denied the Columbia Transmission
    Creditors' Committee's request for a rehearing.  In February 1994, the
    Supreme Court denied petitions for review of the Third Circuit decision.

    Under the Third Circuit ruling, approximately $173 million in refunds that
    Columbia Transmission has received, or expects to receive postpetition from
    upstream pipelines and GRI surcharges collected should be passed through to
    the customers and to the GRI.  In addition, the Third Circuit determined
    that $35 million in upstream pipeline refunds and GRI surcharges, which
    Columbia Transmission collected prior to filing Chapter 11 while received
    in trust, were subject to the "lowest intermediate cash balance test" (the
    amount remaining in trust at the time of bankruptcy) and should be
    distributed on a pro rata basis to the customers and to the GRI to the
    extent of Columbia Transmission's $3.3 million cash balance on July 31,
    1991.  The Third Circuit affirmed another part of the U. S. District
    Court's decision and held that approximately $16 million that Columbia
    Transmission owes upstream suppliers, for gas purchased and transportation
    services received prior to its bankruptcy filing, is ordinary unsecured
    debt which must be discharged in the bankruptcy process.

    On February 10, 1994, the District Court issued an order for the Bankruptcy
    Court to pursue further proceedings in accordance with the Third Circuit's
    refund decision directing the pass-through of these refunds.  At a hearing
    on December 29, 1993, the Bankruptcy Court observed that the Federal Energy
    Regulatory Commission (FERC) should determine whether customers are
    entitled to the actual interest earned on refunds being held by Columbia
    Transmission or the higher FERC-prescribed interest rate.  On February 18,
    1994, Columbia Transmission filed a motion with the FERC for determination
    of this interest issue.  Columbia Transmission will ask the Bankruptcy
    Court for implementation of the mandate.  Columbia Transmission will also
    have to file with the FERC to reimplement its flow-through of Order Nos.
    500/528 refunds from its pipeline suppliers, which represent the majority
    of the refunds at issue.  It is anticipated that Columbia Transmission will
    recommence the flow-through of the upstream pipeline refunds in 1994.

    Total customer claims in Columbia Transmission's bankruptcy proceedings
    relating to, or arising from, Columbia Transmission's contracts with its
    customers for sales, transportation, gas storage and similar services and
    other miscellaneous claims represent about 450 claims for a total of
    approximately $550 million as filed, plus a potentially substantial sum
    filed in undetermined amounts.  Columbia Transmission successfully resolved
    a significant portion of these customer claims.  Not resolved are customer
    claims that total approximately $113 million at December 31, 1993, that
    seek to protect rights associated with any prepetition revenues collected
    subject to refund in general rate filings and purchased gas adjustment
    filings, including matters subject to court appeals.  In addition, the
    claims filed in undetermined amounts, which potentially could be
    significant, still remain to be resolved.  In October 1993, approximately
    $160 million was refunded to customers by Columbia Transmission reflecting
    the terms of a settlement of a 1991 rate case approved by the Bankruptcy
    Court in July 1993.  Bankruptcy Court approval for a 1990 rate case
    settlement for rates in effect from November 1, 1990 through November 30,
    1991 was deferred pending the decision by the Third Circuit regarding the
    flow-through of certain refunds.  Appropriate reserves for rate refund
    liabilities have been recorded for these matters to reflect management's
    judgment of the ultimate outcome of the proceedings.

              RESULTS OF OPERATIONS  (Continued)

    Customer Recoupment Rights
    During the fourth quarter of 1993, various customers of Columbia
    Transmission filed motions with the Bankruptcy Court seeking authority to
    exercise alleged recoupment and setoff rights, whereby they would be
    permitted to reduce amounts owed to Columbia Transmission against refunds
    owed to the customers by Columbia Transmission, including amounts which
    were not otherwise payable in full under the above-mentioned July 1993
    Third Circuit decision, all customer refunds under the 1990 rate case
    settlement and miscellaneous refunds not otherwise payable in full to them.
    Customers are alleging that they have recoupment and setoff rights of
    approximately $83 million at December 31, 1993.

    On October 20, 1993, the Bankruptcy Court approved an interim settlement
    under which customers continued to pay Columbia Transmission for
    FERC-authorized services at authorized rates, and Columbia Transmission has
    agreed to grant these customers a priority claim to the extent the
    Bankruptcy Court finds them entitled to recoupment rights.  In January
    1994, the Bankruptcy Court issued a procedural order whereby other
    customers would be permitted to file recoupment and setoff motions by
    February 18, 1994, with a trial on all such motions scheduled for June
    1994.

    Interest Expense
    Interest expense of the Corporation is not being accrued during bankruptcy
    but a calculation of interest is included in a footnote on the Statements
    of Consolidated Income and Consolidated Balance Sheets.  Such interest has
    been calculated based on management's interpretation of the contractual
    arrangements which govern the various debt instruments the Corporation has
    outstanding exclusive of any redemption premiums.  The Official Committee
    of Unsecured Creditors of the Corporation (Committee) has asserted claims
    for interest which exceed disclosed amounts by approximately $40 million at
    December 31, 1993.  There are several factors to be considered in making
    these calculations that are subject to uncertainty as to their ultimate
    outcome in the bankruptcy proceeding, including the interest rates and
    method of calculation to be applied to overdue payments of principal and
    interest.  In addition, the Committee has asserted that approximately $110
    million of redemption premiums should be paid on high cost debt
    instruments.

              RESULTS OF OPERATIONS  (Continued)

                             OIL AND GAS OPERATIONS

    Market Conditions
    Natural gas markets showed renewed strength in 1993, responding to seasonal
    weather conditions and uncertainty regarding the availability of supplies
    in the new operating environment brought about by FERC Order No. 636 (Order
    636).  Overall for 1993, natural gas prices averaged $2.28 per Mcf compared
    to $2.02 in 1992.  Oil prices continued their decline from a 1992 level of
    $18.20 per barrel to $16.17 per barrel for 1993.

    Capital Expenditures
    The 1993 capital expenditure program increased to $95 million from the $71
    million level in 1992.  The 1993 program provided for increased development
    drilling and a modest exploration program in the southwest.

    In the southwest, Columbia Gas Development Corporation (Columbia
    Development) experienced an increase in both gas and oil production in
    1993, reflecting the continuing success of its drilling program, especially
    its horizontal drilling program in the Austin Chalk Trend in Texas.  During
    the fourth quarter of 1993, Columbia Development drilled and completed its
    100th horizontal well in that area.  Major reconditioning work in early
    1993 also contributed to the increase in production.

    During 1993, 87 gross (46 net) wells were drilled with a 69 percent success
    rate.  Of these, 47 were drilled in the Austin Chalk, 94 percent of which
    were successful.  Productivity was enhanced by an increased emphasis on
    dual lateral wells (multiple lateral wells drilled from a single vertical
    well).  The 44 successful wells drilled included 70 laterals.  This
    substantially increased production while reducing overall cost per well,
    since the costs of the vertical portion of each well were shared by more
    than one lateral and the combined laterals accessed a larger area.  In
    1992, 30 wells with 38 laterals were drilled.

    Horizontal wells drilled in the Austin Chalk formation during 1993 tested
    at average daily rates ranging from 250 to 1,040 barrels of oil and 550,000
    to 3.1 million cubic feet of gas.  Columbia Development holds varying
    interests in these wells.  Development drilling continues in the South
    Harmony Church area in southern Louisiana.  In 1993, three successful wells
    in this area, 100 percent owned by Columbia Development, tested at combined
    rates of seven million cubic feet of gas and 925 barrels of oil per day.

    In the Appalachian area, CNR's 1993 development well program totaled 120
    gross (75 net) wells, with a success rate of 89 percent.  One of the most
    promising areas under development is a formation underlying existing
    production in Ohio, known as Rose Run.  CNR has been producing in this
    formation in recent years with excellent results.  Favorable reservoir
    characteristics allow Rose Run prospects to quickly generate a return on
    invested capital.  CNR's 1994 development program will continue to target
    several prospects in this area.

    The oil and gas segment's total 1994 exploration and development program of
    $91 million will continue to focus primarily on development drilling while
    maintaining the modest level of the 1993 exploration program.  Because of
    weak oil prices the Corporation has adopted more conservative guidelines
    for economic evaluations to reduce risk.

    Reserves
    Net proved natural gas reserves at the end of 1993 totalled 697 Bcf,
    compared to 779.5 Bcf at the end of 1992.  Proved oil, condensate and
    natural gas liquids decreased from 14.7 million barrels at the end of 1992
    to 12.8 million barrels at the end of 1993.  The year end drop in oil
    prices accounted for approximately 0.6 million barrels of the decline by
    rendering some properties uneconomical.  Increased oil prices would result
    in recovery of those reserves.

    As a result of a year end decline from 1992 to 1993 in gas prices together
    with an increase in lifting costs, the





                                       26
<PAGE>   27
    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    recoverable gas reserves for CNR were revised downward 65.9 Bcf (11
    percent).  Without this reduction, newly discovered reserves and extensions
    approximately equaled production.  In addition, Columbia Development's
    Huntington Beach oil recovery waterflood project has shown disappointing
    production during 1993, resulting in revised reserve estimates of 1.1
    million barrels, down 1.6 million barrels from 1992.  Geological and
    engineering analysis of the project is continuing.

    Current pricing has enhanced the profitability of gas prospects, and these
    prospects are the focus of the 1994 capital program.

    Royalty Dispute
    Columbia Development is involved in a $14 million royalty dispute with the
    U.S. Minerals Management Service (MMS) regarding royalty valuation issues
    in connection with prior sales to an affiliate.  As a result of an
    unfavorable lower-court decision regarding the statute of limitations, a
    pre-tax reserve of $5.4 million has been established by Columbia
    Development.  Based on information currently available, management believes
    this reserve to be adequate; however, the contested matters are under
    review, and management is currently negotiating a settlement with the MMS.

    Proposed Rulemaking for Offshore Drilling Financial Responsibility
    The MMS has issued an advance notice of proposed rulemaking for oil spill
    financial responsibility that would establish financial responsibility at
    $150 million for all operators of offshore facilities and facilities in,
    on, or under the navigable waters of the United States.

    Regulations currently require operators to demonstrate financial
    responsibility of up to $35 million in liability coverage.  Both Columbia
    Development and CNR operate in navigable waterways covered under the
    proposed regulations.  The insurance industry has indicated an
    unwillingness to meet the proposed financial responsibility due to certain
    proposed provisions contained in the rulemaking.  Many comments have been
    received by the MMS critical of this rulemaking and its new financial
    responsibility requirement as well as other provisions.  Since final rules
    may be at least two years away, it is impossible to determine the
    implications for the Corporation's oil and gas operations.

    Volumes 
    Gas production totalled 71.5 Bcf in 1993, an increase of 3 percent over
    1992.  The increase includes new Southwest offshore production and new
    onshore production in Texas, south Louisiana and New Mexico.  This
    improvement was tempered by a small decrease in production due to
    construction and maintenance activities on pipelines and compressors
    serving Columbia's Appalachian production area.  After adjusting for the
    1991 sale of the Canadian operations, gas production for 1992 was
    essentially unchanged from the previous year.

    Oil and liquids production in 1993 of 3,603,000 barrels reflected an
    increase of nearly 18 percent compared to 1992 due largely to the success
    of the Southwest program.  Production for 1992, after adjusting for the
    sale of the Canadian operations, increased 228,000 barrels over 1991.

    Operating Revenues
    Higher gas prices together with increases in oil and gas production led to
    operating revenues of $222.2 million in 1993, an increase of 12 percent
    over 1992.  Dampening these improvements was the lower average price for
    oil and liquids and the $5.4 million reserve for the royalty dispute
    discussed above.

    The sale of the Canadian subsidiary was the primary reason for 1992
    operating revenues to decrease $16.1 million from 1991, or 7 percent.  The
    decline was somewhat offset as the average gas price in 1992 was $2.02 per
    Mcf, 7 percent higher than 1991, after adjusting for the 1991 sale of the
    Canadian operations.  The average price for oil





                                       27
<PAGE>   28
    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    and liquids in 1992 of $18.20 per barrel represented a decline of 18
    percent from the price for domestic production the previous year.

    Operating Income (Loss)
    Operating income of $53.6 million in 1993 compares to an operating loss of
    $101.2 million in the prior year which was due largely to recording a
    writedown in the carrying value of oil and gas properties of $126.4 million
    due to depressed energy prices.  The current period improvement in
    operating income also reflected higher operating revenues and lower
    depletion expense.  These improvements were partially offset by higher
    operation and maintenance expense for costs related to new wells and
    additional reconditioning work on older wells.

    The $96.7 million additional operating loss in 1992 compared to 1991
    resulted from the effect of the writedown mentioned above together with
    higher operating expenses.  These declines were mitigated by writedowns
    incurred in 1991 for the Canadian properties.

    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

                            TRANSMISSION OPERATIONS

    Operations
    The transportation and storage rates of Columbia Transmission and the
    transportation rates of Columbia Gulf Transmission Company (Columbia Gulf)
    are currently among the most competitive serving the companies' general
    market areas.  The companies are committed to maintaining their competitive
    position on an ongoing basis through a combination of efficient and
    effective maintenance of existing facilities, economical new market
    development and a commitment to the highest level of overall customer
    satisfaction.

    Columbia Transmission recently received an order from the FERC for the
    construction of the Rutledge Compressor Station in Harford County,
    Maryland.  This station will allow Columbia Transmission to transport
    53,400 Mcf per day to the Eagle Point Cogeneration Plant in New Jersey and
    over 58,000 Mcf per day to New England Power.  It is anticipated that the
    Rutledge Compressor Station will be in service by December 1994.

    Columbia Transmission will provide approximately 52,000 Mcf per day of
    interruptible transportation service to Gordonsville Energy Limited
    Partnership, an independent power producer in Louisa County, Virginia, in
    late summer of 1994.

    Rate Cases
    Columbia Transmission's and Columbia Gulf's rates are subject to the
    jurisdiction of the FERC.  These transmission companies (Transmission) make
    periodic filings for rate changes to recover costs associated with new
    facilities, operating and capital costs, and to reflect changes in
    throughput, cost allocation or rate design.  Settlements of issues related
    to these filings are subject to approval by the FERC, and with respect to
    Columbia Transmission during its bankruptcy, the Bankruptcy Court.

    During 1993, Columbia Transmission and Columbia Gulf sought approval of two
    rate settlements.  As previously reported, a 1990 rate filing by both
    companies covering the period November 1, 1990 through November 30, 1991,
    received FERC approval in 1992; however, Bankruptcy Court approval for
    Columbia Transmission to make refunds has been delayed pending resolution
    of certain motions filed by various creditors.

    Columbia Transmission and Columbia Gulf received FERC and Bankruptcy Court
    approvals for a settlement of a general rate case that went into effect on
    December 1, 1991.  Two parties continue to contest certain aspects of the
    settlement.  Columbia Transmission and Columbia Gulf have made refunds and
    implemented rates prescribed to all parties consenting to this settlement.
    The nonconsenting parties, for whom separate proceedings are expected to be
    scheduled soon, have challenged the FERC's order and have filed a court
    appeal.  In management's opinion, the outcome of the legal proceedings with
    the nonconsenting parties, including the above mentioned court appeal, will
    not have a material adverse impact on the Corporation.

    WACOG Surcharge
    Under the terms of a 1985 settlement with its customers, Columbia
    Transmission is entitled to impose a sales commodity surcharge when its
    weighted average cost of gas (WACOG) met certain conditions.  These
    conditions were met in 1992, and Columbia Transmission was authorized to
    include the surcharge in its rates for the period September 1, 1993 through
    August 31, 1994.  Under Order 636, which became effective November 1, 1993,
    Columbia Transmission essentially eliminated its merchant function and
    proposed an alternative method of recovering these costs which the FERC
    conditionally accepted.

    In January 1994, Columbia Transmission filed a settlement with the FERC
    resolving all issues relating to this unrecovered surcharge.  The
    settlement permits Columbia Transmission to continue collecting a surcharge
    on transportation volumes through October 1994, that would result in the
    opportunity to collect approximately $42.8 million in additional revenues.

    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    Order No. 636
    During 1993, Columbia Transmission and Columbia Gulf implemented the
    restructured services mandated by the FERC's Order 636.  Columbia
    Transmission has virtually eliminated its merchant function and now offers
    a variety of unbundled storage and transportation services.  In order to
    implement this restructuring, the companies made a series of filings with
    the FERC reflecting changes in rates and the terms and conditions under
    which services would be offered.

    On October 22, 1993, Columbia Transmission and Columbia Gulf made their
    final compliance filing before implementing restructured services, under
    Order 636, on November 1, 1993.  In this filing, the companies complied
    with previous FERC orders and made various revisions to the terms and
    conditions applicable to their restructured transportation and storage
    services.  In December 1993, the FERC issued an order on rehearing that
    permitted Columbia Transmission to retain in its rates, costs which the
    FERC had previously determined were associated with its merchant function,
    and approved the level of costs that Columbia Transmission proposed to be
    allocated to interruptible transportation service.

    In the series of orders issued in Columbia Transmission's Order 636
    proceeding, the FERC addressed issues related to Columbia Transmission's
    ability to recover transition costs.  The FERC determined that costs
    incurred by Columbia Transmission as a result of rejecting producer gas
    supply contracts, in its bankruptcy proceeding in 1991, were not eligible
    for recovery as Gas Supply Realignment (GSR) costs under Order 636.  In
    addition, recovery of these costs pursuant to Orders 500 and 528 was
    prohibited by the terms of a 1989 customer settlement.  The FERC determined
    that Columbia Transmission could recover certain contract rejection costs
    through its existing Gas Inventory Charge (GIC), but only to the extent
    such costs were not incurred during the 1991 contract year, a period in
    which Columbia Transmission did not meet the qualifying competitive test
    under the GIC.  If upheld, the FERC rulings, which are subject to pending
    court review, effectively preclude Columbia Transmission from recovering a
    significant portion of the producer contract rejection costs from its
    customers.

    The FERC has generally acknowledged Columbia Transmission's right to seek
    recovery of other types of transition costs.  The FERC approved Columbia
    Transmission's proposal to recover certain purchased gas costs that were
    incurred prior to Order 636 restructuring.  It also agreed to waive a
    nine-month time limit on Columbia Transmission's ability to seek recovery
    of unrecovered purchased gas costs to the extent the costs resulted from
    contracts that are currently in litigation, including bankruptcy
    litigation.  Approximately $60 million in unrecovered purchased gas costs
    were outstanding at December 31, 1993, in addition to approximately $140
    million of prepetition unrecovered purchased gas costs that have not been
    paid due to the bankruptcy filing.

    The FERC also addressed Columbia Transmission's ability to recover costs
    associated with upstream pipeline contracts.  Columbia Transmission
    currently holds firm transportation agreements with certain pipeline
    companies that historically have been used to deliver gas to Columbia
    Transmission.  These contracts have remaining terms of various lengths and
    require the payment of monthly reservation fees whether or not the capacity
    is utilized.  Under Order 636, downstream pipelines such as Columbia
    Transmission are required to offer to assign most of their firm upstream
    capacity to their customers.  Columbia Transmission's annual demand charge
    commitments on these upstream non-affiliated pipelines was approximately
    $108 million; however, assignments of certain of these contracts by
    Columbia Transmission to its customers in conjunction with service
    restructuring under Order 636 have reduced this amount to less than $74
    million.  The total commitment for demand charges after November 1, 1993,
    is approximately $421 million on an undiscounted basis, excluding any
    mitigating effect of the pipelines marketing the capacity to others.

    Subject to review in connection with periodic rate filings, the FERC
    approved Columbia Transmission's proposal to continue to recover costs
    associated with retained upstream pipeline contracts through its demand
    rates.  Recovery of such costs would be subject to review and approval in
    semiannual limited rate filings.  Columbia Transmission





                                       31
<PAGE>   32
    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    has reached settlements that will eliminate approximately half of the
    annual cost of these contracts and is continuing its efforts to negotiate a
    mutually agreeable termination of the remainder of the contracts.

    Columbia Transmission's strategy has been to assume all upstream pipeline
    contracts that can be directly assigned to its customers or need to be
    retained by Columbia Transmission for operational reasons and negotiate
    exit fees for other upstream contracts.  The FERC ruling in the Order 636
    proceedings permits recovery of these exit fees through rates, provided
    that Columbia Transmission can show that they are prudently incurred.
    Columbia Transmission retains the option of rejecting such contracts in its
    bankruptcy proceedings, if appropriate exit fees cannot be negotiated.
    The financial statements reflect a $130 million liability and offsetting
    receivable for the exit fee issue; however, the ultimate cost could vary
    depending on the outcome of ongoing discussions with the affected
    pipelines.

    Several settlements with upstream pipelines have been concluded.  In 1993,
    the Bankruptcy Court approved settlements between Columbia Transmission and
    Texas Eastern Transmission Corporation, Panhandle Eastern Pipe Line Company
    and Texas Gas Transmission Corporation which provide for assumption of
    certain contracts and termination of others.  None of these settlements
    required Columbia Transmission to pay an exit fee to the upstream pipeline.

    In November 1993, the Bankruptcy Court approved a settlement between
    Columbia Transmission and Tennessee Gas Pipe Line Company (Tennessee).
    This settlement provides for Columbia Transmission's assumption of certain
    contracts, the termination of certain other contracts that are no longer
    necessary for Columbia Transmission's operations and payment to Tennessee
    of approximately $42 million in consideration for Tennessee's substantial
    reduction of its major transportation contracts with Columbia Transmission.
    On January 11, 1994, Columbia Transmission and Tennessee made a filing at
    the FERC to approve the settlement.  Columbia Transmission expects to
    ultimately recover the costs and fees associated with the assumption and
    termination of these contracts under Order 636.  The Tennessee settlement
    agreement is conditioned upon this recoverability.

    The FERC affirmed that Columbia Transmission could continue its existing
    rate structure to recover costs associated with its gathering facilities
    through its gathering and other transportation rates until it files a
    general rate case.  Management continues to evaluate the long-term plans
    for Columbia Transmission's gathering facilities which have a net book
    value of approximately $63 million at December 31, 1993.  The regulatory
    treatment of gathering facilities is currently the subject of a generic
    FERC proceeding.  While the ultimate outcome of issues related to
    realization of its investment in gathering facilities is uncertain at this
    time and future charges to income may be required, management believes that
    substantially all of these costs will be recovered through rates or sale of
    the facilities.

    As part of its September 29, 1993 order on Columbia Transmission's and
    Columbia Gulf's Order 636 compliance filings, the FERC initiated a
    proceeding concerning Columbia Gulf's transportation service to Columbia
    Transmission.  Columbia Gulf was directed to show cause as to why it has
    not filed for FERC abandonment authorization to reduce capacity and service
    to Columbia Transmission as required under the Natural Gas Act.  Columbia
    Gulf responded to the show cause order on December 22, 1993.  Management
    does not believe an abandonment filing was necessary and does not expect
    the resolution of this issue to have a material adverse effect on the
    Corporation's financial position.

    One type of transition cost which the FERC acknowledged would be eligible
    for recovery consideration is "stranded costs", which are the costs of a
    pipeline's assets previously used to provide bundled sales service in the
    pre-Order 636 era and are unsubscribed in the Order 636 environment.
    Columbia Gulf has several pipelines and related facilities that are not
    fully subscribed to under Order 636.  Certain facilities south of Rayne,
    Louisiana (primarily in the offshore Gulf of Mexico area), are being
    evaluated; however, management has not identified any stranded facilities
    at this time and the outcome of these evaluations is uncertain.  Dependent
    upon the results of such evaluation, charges to income could be required.
    The net book value of the facilities under study was approximately $40
    million at December 31, 1993. It is management's view that any costs
    associated with these facilities will be fully recoverable through rates.

    Order 94 Settlements
    On January 12, 1994, the FERC granted requests for rehearing of prior
    orders approving settlements between





                                       32
<PAGE>   33
    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    Columbia Transmission and four of its upstream pipeline suppliers relating
    to those suppliers' direct billings to Columbia Transmission of the FERC's
    Order 94 (Order 94) costs in the mid-1980s.  The rehearing orders found
    that the settlements must be rejected because they are expressly contingent
    upon Columbia Transmission's recovery of the Order 94 settlement payments
    from its customers and Columbia Transmission's 1985 PGA Settlement
    essentially bars such recovery.  The orders also hold that these pipelines
    are not entitled to bill any Order 94 charges to Columbia Transmission.
    The FERC ordered these upstream pipelines to refund the principal amounts
    of all Order 94 collections from Columbia Transmission, but waived any
    requirement that these pipelines pay interest on the refunds.  Since
    Columbia Transmission has been reflecting the interest income on these
    refunds since 1990, these orders led to a $19.5 million reduction to
    interest income in 1993.  Columbia Transmission has sought rehearing and,
    if necessary, will seek court review of these orders.  It is expected that
    pipeline suppliers will also request rehearing arguing their rights to
    re-bill such charges to Columbia Transmission.  The ultimate outcome of
    this issue is uncertain at this time and could impact future operating
    results depending upon the results of these additional regulatory and court
    reviews.

    Environmental Matters
    Columbia Transmission and Columbia Gulf are subject to extensive federal,
    state and local laws and regulations relating to environmental matters.
    These laws and regulations, which are constantly changing, require
    expenditures for corrective action at various operating facilities and
    waste disposal sites for conditions resulting from past practices that
    subsequently were determined to be environmentally unsound.

    The transmission subsidiaries have received notice from the United States
    Environmental Protection Agency (EPA) that they are among several parties
    responsible under federal law for placing wastes at Superfund sites and may
    be required to share in the cost of remediation of these sites.  However,
    considering known facts, existing laws and possible insurance and rate
    recoveries, management does not believe the identified Superfund matters
    will have a material adverse effect on future income or on the
    Corporation's financial position.

    The transmission subsidiaries are continuing their comprehensive review of
    compliance with existing environmental standards, including review of past
    operational activities and identification of potential site problems,
    through site reviews and formulation of remediation programs where
    necessary.  The transmission subsidiaries have made progress in these
    ongoing self- assessment programs.  However, because of the thousands of
    miles of pipeline which they operate, the exceptionally large number of
    sites at which they conduct or have conducted operations, and the long
    period over which operations have been conducted, completion of site
    screenings, characterizations and site-specific remediations will require
    approximately 10 to 12 years.  All environmental agencies have been
    declared exempt from the Bar Date established by the Bankruptcy Court for
    claims by creditors.

    A study for Columbia Transmission to quantify the scope of remediation
    activities which will be undertaken in future years to address the issues
    identified was recently concluded.  This study, site investigations and
    characterization efforts performed throughout 1993, resulted in total
    accruals for the year of approximately $60 million for Columbia
    Transmission.  These and other minor adjustments bring Columbia
    Transmission's recorded net liability to $143.6 million at December 31,
    1993. This represents the lower end of the range of reasonable outcomes
    with the upper end estimated to total approximately $280 million based on
    information currently available.

    As characterization and site-specific activities by Columbia Transmission
    determine the nature and extent of contamination at its facilities and as
    remediation plans are developed, additional charges to earnings could
    occur.  To the extent such plans require approval of federal and/or state
    authorities, estimates are subject to revision.  Based on the limited data
    now available and various assumptions as to characterization and
    remediation, management believes that annual future expenditures for
    Columbia Transmission's site investigations, characterization and
    remediation activities could be up to $20 million per year over a 10- to
    12- year time frame.  Since the transmission companies do not account for
    their operations under SFAS No. 71, earnings will continue to be charged as
    costs become probable and reasonably estimable, regardless of when
    expenditures are made.





                                       33
<PAGE>   34
    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

    As a result of site characterization studies at various locations during
    1993, Columbia Gulf recorded an additional accrual of $6.7 million for
    environmental remediation.  This accrual is for polychlorinated biphenyl
    (PCB) cleanup and hydrocarbon spills at certain compressor station sites
    and screenings for possible exposure at other locations.  Columbia Gulf
    anticipates completion of cleanup during 1994.  At that time, costs of
    remediation, if any, will be quantified, and an additional accrual may
    become necessary.

    In 1992, Columbia Transmission received a subpoena and information request
    (Request) from the EPA Region III regarding three major environmental
    statutes:  The Toxic Substance Control Act (TSCA), the Resource
    Conservation and Recovery Act (RCRA), and the Comprehensive Environmental
    Response Compensation and Liability Act (CERCLA).  The Request relates to
    Columbia Transmission's past and current environmental practices.  Since
    receipt of the Request, Columbia Transmission has provided the EPA with
    substantial materials regarding the Request.  Columbia Transmission
    continues to meet with the EPA to attempt to resolve the subpoena issues,
    including related fines and penalties, which it believes will be resolved
    in the near future.

    Columbia Transmission on January 28, 1994 received from EPA Region V an
    Information Request pursuant to RCRA.  The agency requested Columbia
    Transmission to submit information and knowledge relating to its generation
    and management of natural gas pipeline condensate, used engine oil and
    similar liquids in the state of Ohio.  Columbia Transmission is in the
    process of analyzing the information requested and will be discussing this
    Information Request with EPA Region V.

    It is management's continued intent to address environmental issues in
    cooperation with regulatory authorities in such a manner as to achieve
    mutually acceptable compliance plans.  However, there can be no assurance
    that fines and penalties will not be incurred by Columbia Transmission and
    Columbia Gulf.

    The eventual total cost of full future environmental compliance for
    Columbia Transmission and Columbia Gulf is difficult to estimate due to,
    among other things:  (1) the possibility of as yet unknown contamination;
    (2) the possible effect of future legislation and new environmental agency
    rules; (3) the possibility of future litigation; (4) the possibility of
    future designations as a potentially responsible party by the EPA and the
    difficulty of determining liability, if any, in proportion to other
    responsible parties; (5) possible insurance and rate recoveries; and (6)
    the effect of possible technological changes relating to future
    remediation.

    Management expects most environmental assessment and remediation costs to
    be recoverable through rates or insurance.  Although significant charges to
    earnings could be required prior to rate recovery, management does not
    believe that environmental expenditures will have a material adverse effect
    on the Corporation's financial position based on known facts, existing laws
    and regulations and the period over which expenditures are required.

    Clean Air Act Amendments of 1990
    Columbia Transmission and Columbia Gulf have completed preliminary studies
    to determine the impact of the Clean Air Act Amendments of 1990 (CAA-90).
    The studies focused on various compressor facilities for both companies.
    The facilities are among those affected by the new nitrogen oxide emission
    standards under CAA-90.  It is estimated that capital expenditures
    necessary to comply with these new standards could be in excess of $30
    million over the next few years.  However, due to the preliminary nature of
    the studies, the uncertainty of individual state regulations and other
    variables, the actual amount of future expenditures related to CAA-90 is
    difficult to estimate.  Management anticipates that all capital
    expenditures made in compliance with CAA-90 will be recoverable through the
    rate-making process.  Operation and maintenance expenses, including
    monitoring of emissions and permit fees, could approximate $5 million to
    $10 million per year for the transmission companies.

    Partnership Issues
    Columbia Gulf is a general partner in the Trailblazer, Overthrust and Ozark
    pipeline partnerships.  Since these partnerships are nonrecourse
    project-financed pipelines, the partnerships' firm shipper contracts were
    assigned to various banks (or in the case of Ozark, to the Indenture
    Trustee) as collateral for loans.

    fees under Order 636 with the partnerships.  As a result of these
    negotiations and the current depressed demand for capacity in certain of
    the partnerships, the realizability of these investments is uncertain, and
    a valuation reserve of $5.4 million was established in 1993.  It is not
    expected that these issues will be resolved until late 1994.  At December
    31, 1993, Columbia Gulf's investment in the partnerships amounted to $35.4
    million, net of the valuation reserve and before related deferred taxes.

    Cove Point LNG Terminal
    As previously reported, Columbia LNG Corporation (Columbia LNG) has
    developed a new business plan to reactivate the Cove Point facility.
    Originally this plan anticipated a new peaking and storage service by the
    end of 1994, as well as a terminalling service for liquefied natural gas
    (LNG) received by tanker.  However, that plan has been modified to where
    now only a peaking service will be offered initially.  As a consequence,
    Columbia LNG recorded a writedown in the carrying value of its investment
    in the Cove Point facility in the second quarter 1993 that reduced the
    Corporation's income by $37.9 million after-tax.  This amount included
    estimated dismantling costs for the offshore facilities of approximately
    $12 million after-tax.  Until transferred to the new partnership, as
    discussed below, Columbia LNG plans to maintain the offshore facilities for
    possible future imports and at the present time has no plans to abandon or
    dismantle them.

    A partnership between Columbia LNG and a wholly-owned subsidiary of Potomac
    Electric Power Company was formed in October 1993.  The partnership, which
    is pursuing Columbia LNG's business plan filed an application with the FERC
    on November 3, 1993, seeking authorization to acquire all of the existing
    plant and pipeline facilities owned by Columbia LNG and for authorization
    to recommission the plant and construct new facilities in order to provide
    peaking services beginning in 1995.  In addition to the FERC, this
    transaction will require other governmental approvals.  Bankruptcy Court
    approval was received in January 1994.

    The realization of the Corporation's remaining investment in Columbia LNG
    of $10.1 million will be dependent upon successful implementation of the
    partnership and the related business plan.

    Volumes
    Throughput for Transmission includes tariff sales and transportation
    service to local distribution companies (LDCs) and other customers in
    Columbia Transmission's market area, Columbia Gulf's main line
    transportation service from Louisiana to West Virginia and Columbia Gulf's
    short-haul transportation service primarily from the Gulf of Mexico to
    Rayne, Louisiana.  Transmission's throughput in 1993 was 1,355.9 Bcf, a
    decrease of 18.4 Bcf from 1992.  In 1992, throughput increased 144.8 Bcf
    over 1991 to 1,374.3 Bcf.

    A decrease of 13.1 Bcf in market area transportation between 1993 and 1992
    was due primarily to the one-time arrangement in 1992 in which customers
    used market area transportation to repay certain gas delivered to them
    during the 1990 - 1991 winter season by Columbia Transmission.  Throughput
    losses not associated with prior period activity also occurred primarily
    due to competition from other pipelines that began operating under Order
    636 (or a modified version thereof) earlier this year.  As expected, this
    load loss began to reverse following Columbia Transmission's implementation
    of Order 636 in November 1993, when its transportation rates became more
    competitive.  This effect was partially offset by a throughput improvement
    resulting from customers using firm transportation services for delivering
    gas withdrawn from storage during 1993.  In 1992, customers' increased use
    of Columbia Transmission's firm storage service (FSS) led to an increase of
    59.1 Bcf in market area transportation from the year before.

    Columbia Gulf's 1993 mainline transportation service increased 5.6 Bcf from
    1992 and between 1992 and 1991 increased by 38.9 Bcf.  These increases
    primarily reflect additional transportation services for customers to move
    gas to Columbia Transmission's storage under its FSS agreement and to meet
    their supply requirements.  Prior to the implementation of Order 636, a
    portion of Columbia Gulf's mainline capacity was reserved for Columbia
    Transmission's use for deliveries to LDCs and other markets.  Beginning on
    November 1, 1993, however, Columbia Gulf's capacity was assigned to LDCs
    and end users.

              RESULTS OF OPERATIONS  (Continued)

    Short-haul transportation has been increasing in recent years, reflecting
    additional arrangements made by marketers and customers for delivery of
    lower-priced spot market gas.  In 1993, short-haul transportation was
    essentially unchanged from last year and reflected an increase of 60.3 Bcf
    between 1992 and 1991.

    Sales volumes for 1993 decreased 12.3 Bcf from 1992 due primarily to the
    implementation of Order 636.  This decrease was partially offset by colder
    weather in the current period and the timing of prepaid gas sales.
    Comparing 1992 to 1991, sales increased 83.4 Bcf reflecting 10 percent
    colder weather, timing changes for prepaid gas sales and Columbia
    Transmission's competitive market-sensitive commodity rate, that resulted
    from the rejection in Bankruptcy Court of noncompetitive above-market gas
    purchase contracts.

    Net Revenues
    Transmission's 1993 net revenues of $841.5 million increased $80.1 million
    over 1992.  Included in 1993's net revenues are $20.3 million associated
    with the recovery through Columbia Transmission's WACOG surcharge, as
    discussed previously, and GIC revenues of $20.8 million.  1992 GIC revenues
    were $20.9 million.  The GIC mechanism allowed Columbia Transmission to
    charge a fee to customers whose purchases fell below a pre-determined level
    provided Columbia Transmission's cost of gas meets a comparability test
    with competing pipelines.  Also improving 1993 net revenue was an
    adjustment to rate refund reserves and the favorable effect of normal
    weather.  These effects combined with the benefit of the full year effect
    of Columbia Transmission's new rate design where a greater portion of its
    fixed costs are recovered through a monthly demand charge more than offset
    the recording of a loss on the sale of storage inventory.

    Net revenues for 1992 increased to $761.4 million, up $126.9 million over
    1991 principally reflecting improved rate design together with higher
    throughput and GIC revenues.

    Operating Income (Loss)
    Operating income for 1993 of $178.7 million, increased $48.8 million over
    1992.  Higher net revenues together with a 1992 provision for gas supply
    costs combined to more than offset the effect of recording a second quarter
    1993 writedown of $57.5 million for the investment in the Cove Point LNG
    facility (See Note 12F in Notes to Consolidated Financial Statements for
    more information).  Additional reserves for environmental costs of $66.8
    million and $65.3 million were recorded in 1993 and 1992, respectively.
    After adjusting for these and other unusual items, operating income would
    have increased $37.8 million.  These improvements more than offset higher
    operating expenses, including increased labor and benefits costs due in
    part to employee severance costs.  These costs resulted from reengineering
    Transmission's operations to improve the segment's efficiency and
    effectiveness in the increasingly competitive natural gas industry.

    Transmission's 1992 operating income of $129.9 million compares to a loss
    of $1,192.2 million for 1991.  The principal reason for the increase was
    the 1991 provision for gas supply charges of $1,319.2 million.  After
    adjusting for bankruptcy and other unusual items, Transmission's operating
    income would have improved $62.1 million in 1992 over 1991, due to
    increased throughput and rate design changes.

    ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
              RESULTS OF OPERATIONS  (Continued)

                            DISTRIBUTION OPERATIONS

    Market Conditions
    For the first time in four years, weather in the market area served by the
    distribution companies (Distribution) was colder than normal.  Weather was
    only 1 percent colder than normal but 3 percent colder than last year, and
    resulted in a 7.7 Bcf improvement in Distribution's weather sensitive
    deliveries.  In addition, relatively strong economic conditions throughout
    Distribution's service territory, low interest rates, strong new housing
    starts in several key market areas, and moderate unemployment, enabled
    Distribution to add about 28,000 net residential and commercial customers
    during the year, a 1.5 percent growth rate that tracks last year's growth
    and compares favorably with the national average.  Transportation
    deliveries in 1993 increased 13.8 Bcf, 6.8 percent over 1992, reflecting
    strong electric power generation demand and increasing industrial activity.

    Distribution's electric competitors continue to pursue well-organized,
    heavily funded strategic initiatives targeting markets such as space and
    water heating.  Electric companies in Distribution's markets are using a
    variety of aggressive measures such as equipment leasing programs, rebates
    and promotional incentives to make marketing inroads.  These marketing
    efforts have resulted in a reduction of approximately 0.6 percent in
    Distribution's space heating load as a result of electric add-on heat pump
    penetration and a 1.4 percent reduction in gas water heating saturation
    since 1987.  As a result, Distribution has been countering with its own
    strategic programs such as equipment leasing, targeted advertising and
    promotional activity that is designed to bolster Distribution's core
    marketing and counter these negative competitive impacts.

    Distribution's marketing strategy is to augment ongoing development of its
    core residential, commercial, and industrial markets by pursuing
    opportunities to develop new markets for natural gas in the areas of
    natural gas vehicles (NGV), electric power generation and gas cooling.

    Distribution is a leading participant in the gas industry's efforts to
    promote NGVs as alternatives to conventionally fueled fleet and mass
    transit vehicles.  In March 1993, Columbia Gas of Ohio, Inc. (COH) opened
    the nation's largest publicly accessible NGV fueling station in Columbus,
    Ohio.  Distribution operates five other publicly accessible stations and is
    initiating a five-year program to establish approximately 100 additional
    publicly accessible fueling sites throughout its service territory.
    Distribution is also committed to maximizing the number of NGVs in its own
    fleet over the next several years to approximately 2,500, and continues to
    work with commercial and industrial prospects to assist them in evaluating
    NGVs for fleet applications.

    Distribution's concentration on public sector initiatives is also yielding
    results.  Recently, Virginia enacted laws to provide tax credits and
    reduced fuel taxes for alternative fuel vehicles (AFV) as well as require
    federal Clean Fuel Fleet programs in two areas beyond requirements of
    federal law.  Pennsylvania established a $3.5 million fund to provide up to
    a 60 percent grant for purchases of AFVs and AFV filling equipment.
    Pending are initiatives in Kentucky to exempt NGVs from motor fuel testing
    and a proposal in Ohio to provide partial sales and use tax exemptions for
    the purchase of AFVs and filling equipment.

    Distribution continues to actively pursue the developing power generating
    market.  Distribution currently serves 15 power generation and cogeneration
    facilities which consume about 30 Bcf of natural gas each year.  CAA-90
    offers significant new opportunities to promote the use of natural gas for
    electric power generation.  Commonwealth Gas Services, Inc. (COS) reached
    agreement with Gordonsville Energy Limited Partnership to transport gas for
    a new combined cycle generating plant which will produce electric power for
    a Virginia utility beginning in mid-1994 which is expected to use
    approximately 3.0 Bcf of gas annually.  Distribution is currently working
    with five additional prospects, both existing and new electric power

Distribution's customers operate commercial and industrial cooling and
refrigeration systems with a capacity of approximately four million refrigerant
tons.  Less than one percent of this cooling and refrigeration load, roughly
0.2 Bcf, is currently served by gas cooling equipment.  Distribution is
aggressively pursuing this market.  With improved gas cooling equipment, rising
peak electric costs and concerns about the environmental effects of
chlorofluorocarbon refrigerants, Distribution has an opportunity to add
significant load in the summer months when demand for gas is relatively low.
The GRI estimates that 30-50 percent of this market could be served
economically with gas cooling systems.  Sales of gas cooling equipment in
Distribution's service territory increased tenfold in 1993 to 3,096 refrigerant
tons, or about 1.5 percent of total new and replacement equipment sales and 6
percent of large tonnage chiller sales.

Rate Cases
During 1993, Distribution filed two rate cases.  COS filed an expedited rate
case for a $3.5 million annual revenue increase, seeking recovery of increased
operating expenses and a return on additional plant investments since COS' 1992
general rate case.  A final order in this expedited proceeding is expected by
June 1994.

The Virginia State Corporation Commission (VSCC) in October 1993, issued an
order resolving COS' 1992 general rate case.  While the VSCC provided a
favorable increase in annual revenues of $5.6 million, a 4.5 percent increase,
it did not adopt an array of regulatory reform proposals advanced by COS that
included establishing rates based on a fully projected test year and a weather
normalization clause.

In October 1993, the Maryland Public Service Commission approved a rate
settlement for Columbia Gas of Maryland, Inc. (CMD) that provided for a
two-step increase in annual revenues of $2.2 million beginning October 1993,
implementation of a weather normalization adjustment effective with the winter
season which began November 1993, as well as full recovery of postretirement
medical benefit costs.

In contrast to 1993, Distribution's rate activity for 1994 is expected to
accelerate and may involve up to four general rate cases to recover increasing
costs.  Columbia Gas of Pennsylvania, Inc. (CPA) filed a rate case in early
1994 and filings are tentatively scheduled in Ohio for the first quarter and in
Virginia and Kentucky on or about May 1.   Distribution's total revenue request
could range between $90 and $100 million or roughly 5 percent of its total
revenue.  Even though these filings are scheduled early in the year, new rates
will not be effective until the fourth quarter of 1994 or later.  All filings
will incorporate the regulatory initiatives currently being pursued by
Distribution and addressed below.

Strategic Regulatory Issues
Distribution continues to actively pursue an array of regulatory reform
initiatives designed to overcome regulatory barriers in the increasingly
competitive Order 636 era.  It is advocating a comprehensive package of new
services, increased revenue levels and incentive rate mechanisms.  Specific
elements include the use of enhanced projected ratemaking and cost deferral
mechanisms to mitigate adverse timing lags, cost containment and enhanced
customer service and supply initiatives, and revenue stabilization mechanisms
to mitigate the effects of unusual weather conditions and take into account
typical increases in operation and maintenance expenses and capital
expenditures without resorting to time consuming and costly general rate case
proceedings.

While no state commission has yet adopted Distribution's comprehensive reform
package, Distribution has made notable strides in some of its jurisdictions,
including the innovative settlement in Maryland mentioned above reflecting many
elements of its comprehensive initiative.  In Ohio, COH has been involved in
proposed legislation that provides utilities the option of filing rate cases on
a fully projected test year basis.  In Pennsylvania, CPA is supporting a number
of the Public Utility Commission's (PUC) recently announced initiatives aimed
at providing more regulatory responsiveness and flexibility, specifically,
recognizing in rates construction work in progress for certain investments
placed in service after the ratemaking test year.

         RESULTS OF OPERATIONS (Continued)





FERC Order 636
Distribution successfully began the transition into the new environment created
by Order 636.  All of the requirements mandated by the Order have been
implemented by Distribution's interstate pipeline suppliers and thus far
operations have been running smoothly despite the much colder than normal
weather experienced in early 1994.  Over the next several years, additional
pipeline filings and related FERC orders, addressing the recovery of pipeline
transition costs stemming from Order 636, are expected.  However, based on
current estimates of these transition costs and indications from state
commissions, management does not expect the transition costs to have a
significant adverse impact on Distribution's earnings or customer rates.

Gas Supply
Distribution has developed supply arrangements and operating plans and has
aggregated gas supplies to meet market needs in a flexible, cost- effective
manner.  Distribution entered the 1993-94 winter heating season with storage
inventory near maximum levels and with a short-term purchasing/operating plan
designed to fully satisfy firm retail and standby service obligations during
periods that are up to ten percent colder than normal.  Early operating
experience during the extreme cold weather conditions of mid-January 1994, when
peak design conditions were met or exceeded over the course of two consecutive
days, thoroughly tested Distribution's capabilities.  Throughout this
extraordinary period of record-setting peak demands, Distribution's facilities
maintained deliveries and adequate gas supplies were available.  Beyond a few
isolated operating problems and certain brief limitations on customers who
elected to contract for interruptible service, reliable customer service was
maintained.

Environmental Matters
Distribution has initiated a comprehensive environmental program designed to
ensure complete and prompt compliance with all state and federal environmental
requirements.  As part of this program, Distribution is continuing the process
of conducting an environmental assessment of its sites and evaluating
procedures.  The assessment and evaluation process will continue over the next
three to five years.

Distribution's primary environmental issues relate to former manufactured gas
plant sites.  Currently, Distribution has identified twelve former gas plant
sites that it either owned or acquired through facility purchases.
Environmental investigations are being conducted at five of these sites and
remedial action may be required.  Investigations will be conducted at a number
of the other sites in the near future.  Manufactured gas plant sites currently
being investigated include areas in York and Bellefonte, Pennsylvania, and
Portsmouth, Petersburg and Lynchburg, Virginia. (See Note 12H of Notes to
Consolidated Financial Statements for additional information regarding these
sites.)

To the extent site investigations have been completed, remediation plans
developed and any Distribution responsibility for remedial action established,
the appropriate liability has been recorded.  As additional investigations are
completed and remediation costs become probable, the appropriate liability will
be recorded.  As of December 31, 1993, the distribution subsidiaries recorded
net liabilities of $5.9 million for environmental matters.   Management
anticipates recovery of remediation costs through normal rate proceedings.

SFAS No. 106, Employers' Accounting for Postretirement Benefits Other Than
Pensions (OPEB)
Management anticipates that full rate recovery of its accrued OPEB costs in all
states is likely, based on the state commissions' awareness of this issue and
favorable generic policy decisions in a number of jurisdictions coupled with
Distribution's cost management efforts and plans to fully fund all
postretirement benefits allowed in rates in irrevocable trust arrangements.

The present value of the postretirement benefit obligation to be paid to
current and retired employees for all the distribution subsidiaries amounts to
approximately $143.2 million as of December 31, 1993.  Of this amount, $138.1
million has been deferred as a regulatory asset pending anticipated recovery
through rates in various jurisdictions.

The Emerging Issues Task Force (EITF) of the Financial Accounting Standards
Board issued guidelines  establishing criteria for recording such a regulatory
asset, including a requirement for collection of accrual basis expense in rates
and recovery of the transition obligation within approximately 20 years.  These
criteria are not necessarily being adopted by the public utility commissions
regulating the distribution subsidiaries.  Differences in requirements between
the accounting rules and the ratemaking decisions ultimately adopted can result
in a writedown of some or all of this regulatory asset.  The distribution
subsidiaries have implemented cost containment measures designed to reduce
their OPEB obligations.  In addition to other measures, employees will be
required to share a portion of their postretirement health benefit costs and
guidelines have been established redefining years of service requirements
before an employee is eligible for retiree health benefits.  Other cost-saving
plans are being reviewed for consideration in an ongoing effort to effectively
manage OPEB costs.

Integrated Resource Planning
Integrated Resource Planning (IRP) combines the concepts of supply side and
demand side management (DSM).   The DSM component of IRP generally deals with
programs to reduce customer demand, particularly during peak demand periods,
and thereby reduce the need to construct or acquire additional supply capacity.
The supply side component of IRP generally involves the evaluation of supply
options, including the acquisition of supply from alternative sources or supply
arrangements.

IRP was first implemented for electric utilities by state utility commissions
because of the major investments required to add new electric generating
capacity and the resultant impact of these investments on customer rates.
However, state commissions in Distribution's market area are now actively
considering the adoption of natural gas IRP programs.  Distribution generally
regards this as a positive development since it provides a more balanced
competitive situation between gas and electric utilities.  Distribution has
significant concerns that electric DSM programs, if not properly controlled by
state regulators, could result in ratepayer-financed marketing programs and
incentives that would inappropriately influence long-term purchases committing
customers to electric use.

The proper development of gas IRP programs should enable Distribution to
continue to compete for new load and replacement appliances and equipment to
improve system load factors and operating economics.  However, certain
significant competitive concerns remain because electric utilities can
generally support higher incentives for customers to purchase certain electric
appliances because it is far more expensive to expand electric generating
capacity than to expand gas distribution capacity to deliver the same quantity
of useful energy.  Also, most commissions have been reluctant to deal with the
relative environmental impacts of using natural gas versus coal, oil or nuclear
generated electric power for residential and commercial end uses, which would
result in reduced overall emissions and provide higher incentives for gas
usage.

Distribution's IRP efforts are designed to encourage state regulators to deal
with utility IRP programs on a comprehensive basis.  Distribution believes that
under such an approach, commissions are more likely to recognize the many
significant advantages of using natural gas rather than electricity for most
residential and commercial and many industrial end uses or at a minimum, work
to maintain more competitive parity between gas and electric rates.
Distribution is working aggressively to communicate the many advantages of a
comprehensive approach to IRP.

Volumes
Throughput for 1993 totaled 509.8 Bcf, a 23.1 Bcf increase over 1992.  Higher
transportation deliveries of 13.8 Bcf were due mainly to increased usage by
power generating facilities in Virginia and Pennsylvania. The 9.3 Bcf increase
in tariff sales volumes reflects higher customer usage due primarily to 3
percent colder weather and the net addition of approximately 28,000 customers.

Distribution's throughput for 1992 increased 30.3 Bcf over 1991 after adjusting
for the 1991 sale of a New York subsidiary.  Despite 1992 being 2 percent
warmer than normal, it was still 10 percent colder than the prior year.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (Continued)




This colder weather and the net addition of 28,000 new customers led to higher
sales volumes.  Transportation volumes also increased in 1992 due largely to
increased deliveries to power-generating facilities as well as other customers
using this service to meet their supply requirements.

Net Revenues
For the year ended December 31, 1993, net revenues of $726 million reflected an
increase of $29.5 million over the same period last year.  Increased throughput
generated $18.7 million of this improvement.  Additionally, new rates in effect
during 1993 in Virginia and Maryland and the full year impact of rates placed
in effect in 1992 combined to generate $7.6 million with revenues for fixed
charges from new customers accounting for most of the remaining $3.2 million
increase.

Colder weather was the principal reason for 1992's net revenues increasing to
$696.5 million.  After adjusting for the sale of the New York subsidiary in
1991, the net revenues in 1992 represented an increase of $62 million over
1991.  The full year effect of favorable rate settlements in all of
Distribution's operating areas also contributed to the higher net revenues.

Operating Income
Operating income improved $8.7 million over the previous year.  Higher net
revenues of $29.5 million were partially offset by increased operating expenses
of $20.8 million.  An $8.8 million increase in operation and maintenance
expense reflecting wage increases, additional personnel requirements associated
with the implementation of Order 636, as well as the filling of certain
vacancies that had been deferred and higher lease costs for the Columbus, Ohio
headquarters building were the primary reasons for the increase.  Additionally,
costs for the streamlining of corporate service functions and studies underway
to enhance customer service also contributed to the increase.  These increases
were partially offset by a $4.2 million charge recorded in 1992 for COS OPEB
costs.  Depreciation expense increased $4.7 million primarily reflecting plant
additions, while increased gross receipts taxes and property taxes of $7.3
million were attributable to higher taxable revenues and plant additions.

After adjusting for the sale of the New York subsidiary, operating income in
1992 of $137.7 million increased $27 million over 1991 as higher net revenues
were partially offset by increased operating expenses.  Increased operating
expenses of $558.8 million resulted primarily from higher labor and benefit
costs and the effect of regulatory lag that resulted in only a portion of
increased costs being recovered through rates.

Cogeneration
Independent power production continues to be a growth area for natural gas.
The Corporation is involved in several cogeneration projects through TriStar
Ventures Corporation (TriStar), a wholly-owned subsidiary.  Projects in
operation or under construction total nearly 300 megawatts in which TriStar
holds various interests.  Three cogeneration facilities are now operating; a
117-megawatt facility in Pedricktown, New Jersey, a 50-megawatt plant in
Binghamton, New York and an 85-megawatt plant in Rumford, Maine.  Natural gas
is delivered to the Binghamton and Pedricktown facilities by Columbia
Transmission.  These three projects generated $5.8 million and $4.5 million of
income before interest and income taxes in 1993 and 1992, respectively.  A
47-megawatt plant near Vineland, New Jersey is scheduled to begin operations in
mid-1994.  TriStar and its partners also have other projects in various stages
of development.  Value is also generated from the projects for the transmission
subsidiaries of the Corporation who benefit from increased throughput while the
oil and gas segment has increased sales opportunities.

TriStar was participating in the development of a 56-megawatt plant in
Washington, D.C. on which construction had been delayed pending regulatory
review and approval.  On October 13, 1993, processing of the building permit
was suspended indefinitely by the District of Columbia.  This action combined
with numerous regulatory delays, caused the project to become financially
nonviable.  Accordingly, TriStar and its partner halted efforts to build the
project and TriStar wrote off its net investment in the project of $3.1 million
after-tax.  On November 1, 1993, the partnership filed an $80 million lawsuit
in federal court against the District of Columbia and certain District
officials.

Propane
During 1993, propane sales by Columbia Propane Corporation and Commonwealth
Propane, Inc., totaled 58.1 million gallons, a decrease of 8 percent from the
previous year.  The propane companies serve approximately 68,000 customers in
parts of Maryland, North Carolina, Ohio, Pennsylvania, Virginia and West
Virginia.  The companies are focusing their sales efforts on the higher-margin
residential segment.

Coal Operations
The Corporation has in excess of 500 million tons of coal reserves.
Approximately 50 percent of the reserves, much of which contain less than one
percent sulfur, are leased to other parties for development.

Environmental Matters
The Columbia Gas System Service Corporation (Service Corporation) received a
"General Notice of Potential Liability and CERCLA Section 104(2) Request for
Information" concerning a process site to which the Service Corporation sent
certain solvents.  This notice was sent to in excess of 100 parties requesting
information about any involvement with the owner of the site or the site
itself.  Management has furnished the information requested and  does not
believe this Superfund matter will have a material adverse effect on future
income or on the Corporation's financial position.

Net Revenues
Propane sales to wholesale and industrial customers have been decreasing over
the past few years due to unacceptable margins while, to a lesser extent, sales
to higher-margin residential customers have been increasing.  As a result of
this strategy, total sales volumes have decreased, but net sales revenues have
been rising.  This change led to net sales revenues of $29.8 million in 1993,
an increase of $2.5 million, and in 1992 an increase of $700,000 compared to
the year earlier.  Increases in revenues resulting from gas marketing
activities were largely offset by increased products purchased expense.

Revenues in 1993 from services provided to affiliates and coal royalties
resulted in an increase in other revenues of $3.1 million, to $73.4 million,
from the prior year.  Other revenues in 1992 of $70.3 million, were $5.2
million

         RESULTS OF OPERATIONS (Continued)




lower than the year earlier primarily because a decrease in revenues from
affiliate companies more than offset higher coal royalty revenues.

Operating Income
The net revenue increase of $5.6 million was more than offset by $10.7 million
higher operating expenses primarily reflecting increased labor and benefits
costs that included employee severance costs recorded in 1993.  The 1992 net
revenue decline of $4.5 million compared to 1991 was more than offset by
reduced operating expenses of $6.4 million, resulting from lower labor and
benefits costs in 1992 due to a reduction in the number of employees and a
charge in 1991 for employee severance costs.

                              CONSOLIDATED REVIEW

Net Income
The Corporation reported net income for 1993 of $152.2 million, or $3.01 per
share, compared to $51.2 million, or $1.01 per share in 1992.  After adjusting
for the unusual and bankruptcy related items detailed below, 1993 net income of
$155.1 million was up $56.4 million over the prior year.  The oil and gas,
transmission and distribution segments all experienced improved results in
1993.  These improvements resulted from increased throughput, the full year
effect of a new rate design implemented by the transmission companies as well
as lower depletion expense, higher prices for gas production and increased oil
and gas production for the oil and gas segment.  The distribution segment's
results improved because the weather was 3 percent colder than 1992 and because
of higher transportation volumes.

  recover costs when it meets certain competitive tests for its commodity sales
  rate or cost of gas.

Operating Income by Segment
The oil and gas segment had operating income of $53.6 million in 1993, compared
to an operating loss of $101.2 million in 1992.  The prior period loss was
mainly due to a writedown of $126.4 million in the carrying value of oil and
gas assets due to low energy prices.  Lower depletion expense, higher gas
prices and increased oil and gas production also contributed to the current
period increase and were only partially offset by lower oil and liquids prices
and the recording of a reserve for a royalty dispute with the MMS.  The average
gas price in 1993 was $2.28 per Mcf, up $0.26 per Mcf over last year, whereas
the average price for oil and liquids decreased to $16.17 per barrel, down
$2.03 per barrel from 1992.  Oil and gas production for 1993 of 3,603,000
barrels and 71.5 Bcf, increased 542,000 barrels and 2.3 Bcf, respectively, over
last year.

The transmission segment's 1993 operating income of $178.7 million, up $48.8
million, reflected a significant improvement over the 1992 level.  After
adjusting for the pre-tax effect of the unusual items, operating income
increased $37.8 million over 1992.  Included in these unusual items are 
increased revenues from GIC and WACOG





                                      48

         RESULTS OF OPERATIONS (Continued)




revenues Columbia Transmission is permitted to recover from its customers when
it met certain competitive tests with other pipelines.  These sources of
revenue were unique to Columbia Transmission's merchant function which was
essentially eliminated under Order 636.  After adjusting 1992 throughput for a
customer exchange arrangement, throughput improved resulting in higher
revenues.  This effect together with the full year effect in 1993 of Columbia
Transmission's new rate design were the principal reasons for the $37.8 million
improvement.  Under this new rate design, a greater portion of fixed costs are
collected through a monthly demand charge rather than the commodity charge
where they are susceptible to weather fluctuations.  Gas costs continue to be
recovered through commodity charges.  Also contributing to the 1993 improvement
over 1992 was approximately $15 million of additional expense recorded in the
prior period for settlements with a supplier.

Weather in the distribution segment's service areas was 3 percent colder than
1992.  The colder weather helped raise 1993 operating income to $146.4 million,
an increase of $8.7 million over 1992.  Improved recovery of costs through
higher rates in effect in Virginia and Maryland contributed to the increase.
Mitigating these improvements were higher operating expenses that included
increases in labor and benefits expense and costs associated with streamlining
corporate service functions and studies underway to enhance customer service.

Other energy operations had operating income of $1.7 million, a decrease of
$5.1 million compared to 1992.  The reduction primarily reflects recording $6.3
million for costs associated with the Service Corporation's reengineering
program.

Revenues
Operating revenues for 1993 of $3,391.2 million, increased more than 16 percent
from the year earlier largely due to the full year effect of Columbia
Transmission's new rate design, pipeline exit fees of $130 million for Columbia
Transmission, higher retail sales resulting from colder weather during 1993 and
higher distribution rates.  In addition, Columbia Transmission's WACOG
revenues, sale of storage to customers, higher gas prices and increased oil and
gas production also contributed to the improvement.  Revenues associated with
pipeline exit fees were offset in products purchased expense and had no effect
on income.

Operating revenues for 1992 increased $345.2 million over 1991 to $2,922
million due to a combination of higher sales volumes as a result of colder
weather, the full year effect of higher distribution rates and Columbia
Transmission's new rate design and more competitive sales rate.

Expenses
Over the last three years, higher sales necessitated an increase in volumes of
gas purchased resulting in an increase in products purchased expense of $337.6
million in 1993, compared to 1992, and $180.4 million for 1992 over 1991.  In
addition, higher average rates for gas purchased, particularly spot market
purchases, also contributed to the increase in 1993.  Higher expense for
pipeline exit fees were offset in revenues as mentioned above.

In 1992, Columbia Transmission anticipated only a minimal merchant function
would be offered when Order 636 was implemented in November 1993; therefore, a
provision for gas supply charges of $38.6 million was recorded to reflect a
writedown of certain capitalized gas costs in excess of amounts to be amortized
in 1993.

Higher labor and benefits expense in 1993, which included $14.8 million for
severance costs associated with reengineering many of the System functions to
gain efficiencies and improve competitiveness, together with rising operating
costs led to higher operation and maintenance expense of $26.5 million.
Partially offsetting these increases was higher expense in 1992 for certain
supplier settlements by Columbia Transmission.  Raising expense in both 1993
and 1992 were environmental costs of $66.8 million and $65.3 million,
respectively.

The higher environmental costs recorded in 1992 and increased labor and
benefits expense of Columbia Transmission

<PAGE>   50
ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (Continued)




were the primary reasons for the $111.3 million increase in operation and
maintenance expense over 1991.  Additional expenses in 1992 associated with
certain producer settlements also contributed to the increase.

Due to depressed energy prices in early 1992, a writedown was recorded of
$126.4 million in the carrying value of oil and gas properties.  This was the
principal reason for the $128.3 million decrease in 1993 in depreciation and
depletion expense.  The significant increase in depreciation and depletion
expense of $83.1 million in 1992 over 1991 was also the result of this
writedown, which was partially offset by writedowns for the Canadian oil and
gas properties in 1991.

Income Taxes
As detailed in Note 5 of Notes to Consolidated Financial Statements, income
taxes in 1993 increased $65.4 million over last year reflecting increased
income, adjustments due to the IRS settlement and the increased tax rate.  In
1992, income taxes increased $481.5 million as the Corporation had pre-tax book
income in 1992 compared to a loss in 1991.

Other Income (Deductions)

Other Income (Deductions) reduced income in 1993 and 1992 by $85.3 million and
$1.5 million, respectively. In 1993, interest expense increased $87.8 million
due largely to recording interest on prior years' taxes of $74.5 million
primarily as a result of the IRS settlement.  Interest income and other, net
decreased $13.2 million primarily reflecting $19.5 million for a FERC order
eliminating interest payments from certain upstream pipeline suppliers and a
reserve for pipeline partnership investments partially offset by increased
interest income on prior years' taxes and other issues.  Income was improved in
1993 and 1992 by approximately $212.4 million and $224.9 million, respectively,
from not accruing interest expense for prepetition obligations.  (Since the
July 31, 1991 bankruptcy filing, the estimated effect of not accruing interest
expense on these prepetition obligations totals approximately $523 million.
However, the actual interest that will ultimately be paid pursuant to the final
plans of reorganization could differ significantly and cannot be determined at
this time.)  Reorganization items, net reflects bankruptcy issues that improved
income $8.9 million in 1993 compared to an income decrease of $8.3 million last
year.  Included in these amounts is $39.9 million of interest earned on
accumulated cash, up $13 million over 1992, and $31 million for 1993
professional fees and related expenses together with other miscellaneous
reorganization items, a decrease of $4.2 million from last year.

In 1992 Other Income (Deductions), net reduced income $1.5 million versus
$119.4 million in 1991.  Income was improved in both 1992 and 1991 by not
accruing interest expense on prepetition obligations by approximately $224.9
million and $85.6 million, respectively.  The decrease of $11.9 million in
Interest Income and Other, net was due to several items including a $17.9
million gain in 1991 on the sale of the New York distribution subsidiary and a
$2.9 million gain on the 1991 sale of the Canadian oil and gas properties.
These items were partially offset by a $14.5 million writedown for certain
cogeneration projects.  The change between 1992 and 1991 for bankruptcy issues
increased income $6.1 million.  Professional fees and related expenses,
combined with other miscellaneous reorganization items, were $35.2 million and
$18.9 million in 1992 and 1991, respectively, while interest earned on
accumulated cash was $26.9 million in 1992 and $4.5 million in the prior year.

</TABLE>

                        LIQUIDITY AND CAPITAL RESOURCES

Cash from Operations
The full year effect of Transmission's new rate design, higher rates for
Distribution and colder weather during 1993 compared to last year, together
with certain refunds received from suppliers, resulted in net cash from
operations of $850.4 million, an increase of $85 million for 1993.  Higher oil
and gas production and increased gas prices also contributed to this
improvement.  Cash received from customers increased $412 million in 1993,
primarily reflecting increased volumes due to colder weather earlier in the
year together with higher rates.  The receipt of rate refunds by certain
subsidiaries led to the $79.4 million rise in other operating cash receipts.
An increase in the spot market price for gas and additional gas volumes
purchased to meet customer requirements resulted in $302.2 million more cash
being paid to suppliers partially offsetting the above cash improvements.  In
addition, a refund payment by Columbia Transmission led to a $102 million rise
in other operating cash payments in 1993.

Colder weather in 1992 compared to the prior year and the suspension of
interest payments on August 1, 1991, due to the bankruptcy filing raised net
cash from operations $233.8 million to $765.4 million in 1992 over 1991.
Higher 1992 throughput from colder weather, increased receipts due to
implementing a new rate design for Columbia Transmission and higher
distribution rates were the primary reasons for the $300.5 million increase in
cash received from customers.  The suspension of interest payments on
prepetition debt obligations led to the $100.4 million decrease in interest
paid.  Partially offsetting these improvements was the 1991 receipt of a
settlement payment on a property dispute which caused other operating cash
receipts to decline $48 million.  Also, higher income taxes due to timing
differences between periods and increased property tax assessments caused
income taxes paid and other tax payments to increase $40.6 million and $31.5
million, respectively.

The Corporation maintains a debtor-in-possession facility (DIP Facility) for up
to $100 million, including the availability of letters of credit of up to $50
million.  The DIP Facility is available for use in conjunction with internally
generated funds for general corporate purposes and to provide financing for
subsidiaries not involved in the bankruptcy proceedings.  As of January 31,
1994, $12.7 million of letters of credit were outstanding under the

<PAGE>   52
ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         ESULTS OF OPERATIONS (Continued)




DIP Facility.  The DIP Facility expires December 31, 1994, although a request
to extend it will be made, if necessary.  During 1993, there were no borrowings
under the DIP Facility.  Absent unusual circumstances, the Corporation expects
to remain in a cash surplus position during all of 1994.  As of January 31,
1994, the Corporation and its subsidiaries, excluding Columbia Transmission,
had excess cash of $148 million, which was invested in money market
instruments.

The liquidity needs of Columbia Transmission are being satisfied by internally
generated funds.  As of January 31, 1994, Columbia Transmission had $1,250.9
million invested in money market instruments through a wholly-owned subsidiary,
Columbia Transmission Investment Corporation.  Columbia Transmission also
maintains a DIP Facility solely for the issuance of letters of credit for up to
$25 million.  As of January 31, 1994, the balance of outstanding letters of
credit under Columbia Transmission's DIP Facility was $1.8 million.  In
December 1993, Columbia Transmission extended its DIP Facility through December
31, 1995.

The Corporation's subsidiaries (other than Columbia Transmission during
bankruptcy) must receive SEC approval under the Public Utility Holding Company
Act of 1935 for all financing.  As part of the approval process, the
Corporation files the financing requirements of each of its subsidiaries with
the SEC along with other material supporting management's opinion that the
amounts requested are in the best interest of the Corporation's investors.  In
connection with recent filings, the Corporation has been requested to provide
greater detail in support of the financing of subsidiaries which have, from
time to time, experienced losses.  These companies include:  Columbia LNG,
TriStar, TriStar Capital Corporation, Columbia Coal Gasification Corporation
and Columbia Development.  The need to provide information requested by the SEC
to satisfy these concerns has made the receipt of timely approval more
difficult and future delays could be experienced.  However, management
continues to believe it will receive approval of its financing requests.

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

</TABLE>
Capital expenditures for 1993 were $361 million, an increase of $61 million
over 1992.  The increase reflects expenditures on some projects that had been
deferred in previous years.  In 1992 and 1991, the Corporation's subsidiaries
reduced capital expenditures to the extent possible consistent with the need to
maintain safe and efficient operating facilities, the need to meet new service
and tariff obligations, drilling commitments and the need to preserve going
concern values.

Some of the Corporation's subsidiaries will be initiating projects that can no
longer be deferred which will increase the 1994 program $107 million, to $468
million.

In 1994, Distribution will make investments of approximately $18 million to
improve the efficiency of support services where expenditures had previously
been deferred.  Also included in Distribution's 1994 capital expenditure
program are expenditures to provide deliveries to gas powered electric
generating plants in its market areas and third-party natural gas vehicle
public refueling stations.  The majority of the transmission companies'
expenditures will be for maintaining their extensive pipeline and storage
system.  In addition, $26 million is included for a project to provide gas to a
New England electric generating facility which has been deferred since 1990
pending regulatory approval.  Expenditures in 1994 for the oil and gas segment
will remain essentially at 1993 levels.  The current weakness in oil prices has
resulted in a reduction in planned 1994 expenditures for exploratory drilling.
The majority of the segment's expenditures will be for less risky development
drilling.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Shareholders of The Columbia Gas System, Inc.:

We have audited the accompanying consolidated balance sheets of The Columbia
Gas System, Inc. (a Delaware corporation, the "Corporation") and subsidiaries
as of December 31, 1993 and 1992, and the related statements of consolidated
income, cash flows and common stock equity for each of the three years in the
period ended December 31, 1993.  These financial statements are the
responsibility of the Corporation's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Corporation and
subsidiaries as of December 31, 1993 and 1992, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1993, in conformity with generally accepted accounting principles.

On July 31, 1991, the Corporation and Columbia Gas Transmission Corporation
("Columbia Transmission"), a wholly-owned subsidiary, filed separate petitions
seeking protection under Chapter 11 of the Federal Bankruptcy Code.  Note 2
discusses, among other matters, uncertainties associated with the Chapter 11
proceedings, including the status of the Corporation's loans to Columbia
Transmission, certain prepetition intercompany asset transfers and the
measurement of certain liabilities.  This note also discusses purported class
action and other complaints which have been filed against the Corporation
generally alleging violations of certain securities laws.  The accompanying
financial statements do not reflect any liability associated with these
complaints as the Corporation believes it has meritorious defenses to these
actions; however, the ultimate outcome is uncertain.  As a result of these
matters, the Corporation may take, or be required to take, actions which may
cause assets to be realized or liabilities to be liquidated for amounts other
than those reflected in the financial statements.  These factors create
substantial doubt about the Corporation's ability to continue as a going
concern.  The accompanying financial statements have been prepared assuming
that the Corporation and Columbia Transmission will continue as going concerns
which contemplates the realization of assets and payment of liabilities in the
ordinary course of business.  The appropriateness of the Corporation continuing
to present financial statements on a going concern basis is dependent upon,
among other items, the terms of the ultimate plan of reorganization and the
ability to generate sufficient cash from operations and financing sources to
meet obligations.

As discussed in Note 4, effective January 1, 1991, the Corporation changed its
method of accounting for income taxes and postretirement benefits other than
pensions pursuant to standards promulgated by the Financial Accounting
Standards Board.

The schedules listed in the Index to Item 8, Financial Statements and
Supplementary Data, are the responsibility of the Corporation's management and
are presented for purposes of complying with the Securities and Exchange
Commission's rules and are not part of the basic consolidated financial
statements.  These schedules have been subjected to the auditing procedures
applied in the audits of the basic consolidated financial statements and, in
our opinion, fairly state in all material respects the financial data required
to be set forth therein in relation to the basic consolidated financial
statements taken as a whole.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   A.    PRINCIPLES OF CONSOLIDATION.  The Consolidated Financial Statements
         include the accounts of the Corporation and all subsidiaries.  All
         intercompany accounts and transactions have been eliminated, except
         for the Corporation's investment in Columbia LNG Corporation (see Note
         12F).

         On July 31, 1991, the Corporation and its wholly-owned subsidiary,
         Columbia Gas Transmission Corporation (Columbia Transmission), filed
         separate petitions seeking protection under Chapter 11 of the Federal
         Bankruptcy Code.  The debtor companies are operating their businesses
         as debtors-in-possession (DIP) under the jurisdiction of the United
         States Bankruptcy Court for the District of Delaware (Bankruptcy
         Court).  As such, the debtor companies cannot engage in transactions
         considered to be outside the ordinary course of business without
         obtaining Bankruptcy Court approval (see Note 2).

         The accompanying financial statements reflect all adjustments
         necessary in the opinion of management to present fairly the results
         of operations in accordance with generally accepted accounting
         principles applicable to a going concern.  Such presentation
         contemplates the realization of assets and payment of liabilities in
         the ordinary course of business.  As a result of the reorganization
         proceedings under Chapter 11, the debtor companies may take, or be
         required to take, actions which may cause assets to be realized, or
         liabilities to be liquidated, for amounts other than those reflected
         in the financial statements.  The appropriateness of continuing to
         present consolidated financial statements on a going concern basis is
         dependent upon, among other things, the terms of the ultimate plan of
         reorganization, future profitable operations, the ability to comply
         with DIP and other financing agreements and the ability to generate
         sufficient cash from operations and financing sources to meet
         obligations.  The consolidated financial statements do not include any
         adjustments relating to the recoverability and classification of
         recorded asset amounts, or the amounts and classification of
         liabilities that might be necessary as a result of the outcome of the
         uncertainties discussed herein.

         Certain reclassifications have been made to the 1992 and 1991
         financial statements to conform to the 1993 presentation.

   B.    BASIS OF ACCOUNTING FOR RATE-REGULATED SUBSIDIARIES.  Statement of
         Financial Accounting Standards (SFAS) No. 71, "Accounting for the
         Effects of Certain Types of Regulation," provides that rate-regulated
         public utilities account for and report assets and liabilities
         consistent with the economic effect of the way in which regulators
         establish rates, if the rates established are designed to recover the
         costs of providing the regulated service and if the competitive
         environment makes it reasonable to assume that such rates can be
         charged and collected.  The Corporation's interstate transmission
         companies did not meet these criteria, and consequently are not
         applying the provisions of SFAS No. 71.  In 1992, management concluded
         that it was no longer appropriate for Columbia LNG Corporation
         (Columbia LNG) to continue application of SFAS No. 71 (see Note 12F).
         The Corporation's gas distribution subsidiaries follow the accounting
         and reporting requirements of SFAS No. 71.

   C.    GAS UTILITY AND OTHER PLANT AND RELATED DEPRECIATION.  Property, plant
         and equipment (principally utility plant) are stated at original cost.
         The cost of gas utility and other plant of the distribution companies
         includes an allowance for funds used during construction (AFUDC).

         In addition, Columbia Gas of Ohio, Inc. is permitted to include in its
         plant investment post-in-service carrying charges on those eligible
         plant investments which are placed in service between December 31,
         1990, and December 31, 1994.   Subject to commission approval, the
         carrying charges are also authorized





                                           61

         to be included in base rates in subsequent rate filings.  These
         carrying charges are subject to a net income limitation, as 
         determined by the commission.  Property, plant and equipment of other
         subsidiaries includes interest during construction (IDC).

         The 1993, 1992 and 1991 before-tax rates for AFUDC and IDC were 8.0
         percent and 9.6 percent, respectively.  They represent the rates in
         effect prior to Chapter 11 filings.  The portion of interest
         capitalized by subsidiaries during the period the Corporation is in
         bankruptcy is eliminated in the Consolidated Financial Statements.

         Improvements and replacements of retirement units are capitalized at
         cost.  When units of property are retired, the accumulated provision
         for depreciation is charged with the cost of the units and the cost of
         removal, net of salvage.  Maintenance, repairs and minor replacements
         of property are charged to expense.  The Corporation's subsidiaries
         provide for annual depreciation on a composite straight-line basis.

         The average annual depreciation rate for Transmission property was 2.6
         percent in 1993, 1992 and 1991.  The average annual depreciation rate
         for Distribution property was 3.3 percent in 1993 and 1992, and 3.6
         percent in 1991.

   D.    OIL AND GAS PRODUCING PROPERTIES.  The Corporation's subsidiaries
         engaged in exploring for and developing oil and gas reserves follow
         the full cost method of accounting.  Under this method of accounting,
         all productive and nonproductive costs directly identified with
         acquisition, exploration and development activities are capitalized in
         a countrywide cost center.  If costs exceed the sum of the estimated
         present value of the cost center's net future oil and gas revenues and
         the lower of cost or estimated value of unproved properties, an amount
         equivalent to the excess is charged to current depletion expense.
         Gains or losses on the sale or other disposition of oil and gas
         properties are normally recorded as adjustments to capitalized costs.

         Depletion for domestic subsidiaries is based upon the ratio of
         current-year revenues to expected total revenues, utilizing current
         prices, over the life of production.  Depletion for the Canadian
         subsidiary, which was sold as of December 31, 1991, was based upon 
         the ratio of volumes produced to total reserves.

   E.    COMMODITY HEDGING.  Commodity futures, options on futures, and
         commodity price swaps are used from time to time to hedge prices of
         crude oil, natural gas production, propane inventories and commitments
         for natural gas purchases and sales, in order to minimize the risk of
         market fluctuations.  Under internal guidelines, hedging positions 
         for oil and gas production can be taken for up to 80 percent of the
         expected uncommitted monthly production.  Gains and losses on the
         hedging transactions are recognized when the hedged commodity is sold
         or purchased.

   F.    GAS INVENTORY.  Gas inventory is carried at cost on a last-in,
         first-out (LIFO) basis.  The estimated replacement cost of gas
         inventory in excess of carrying amounts at December 31, 1993, was
         approximately $85 million for the distribution companies.  
         Liquidation of LIFO layers related to gas delivered by the distribu-
         tion companies does not affect income since the effect is passed 
         through to customers as part of purchased gas adjustment tariffs.  
         As a result of implementing Federal Energy Regulatory Commission 
         (FERC) Order No. 636 (Order 636), Columbia Transmission substantially 
         eliminated its merchant function and, therefore, no longer carries a 
         gas inventory.  Amounts previously recorded as "Gas Inventory - 
         Noncurrent" have been reclassified to Property, Plant and Equipment 
         which represents the volume of gas required to maintain pressure 
         levels for storage service.

   G.    INCOME TAXES AND INVESTMENT TAX CREDITS.  The Corporation and its
         subsidiaries record income taxes to recognize full interperiod tax
         allocations.  Under the liability method, deferred income taxes are





                                       62
<PAGE>   63
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         recognized for the tax consequences of temporary differences by
         applying enacted statutory tax rates applicable to future years to
         differences between the financial statement carrying amounts and the
         tax basis of existing assets and liabilities.

         Previously recorded investment tax credits of the gas distribution
         subsidiaries were deferred and are being amortized over the life of
         the related properties to conform with regulatory policy.

   H.    ESTIMATED RATE REFUNDS.  Certain rate-regulated subsidiaries collect
         revenues subject to refund pending final determination in rate
         proceedings.  In connection with such revenues, estimated rate refund
         liabilities are recorded which reflect management's current judgment
         of the ultimate outcome of the proceedings.  No provisions are made
         when, in the opinion of management, the facts and circumstances
         preclude a reasonable estimate of the outcome.

   I.    DEFERRED GAS PURCHASE COSTS.  The Corporation's gas distribution
         subsidiaries defer differences between gas purchase costs and the
         recovery of such costs in revenues, and adjust future billings for
         such deferrals on a basis consistent with applicable tariff
         provisions.

   J.    REVENUE RECOGNITION.  The Corporation's rate-regulated subsidiaries
         bill customers on a monthly cycle billing basis.  Revenues are
         recorded on the accrual basis including an estimate for gas delivered
         but unbilled at the end of each accounting period.  Columbia
         Transmission also records the impact on revenues of the future
         recovery or refund of differences between current gas and
         transportation costs and amounts currently included in the billed
         rates.  In addition, Columbia Transmission and Columbia Gulf record
         the effect on revenues to reflect the recovery or refund of
         differences between current fuel usage and amounts retained.

2.  REORGANIZATION PROCEEDINGS UNDER CHAPTER 11 OF THE BANKRUPTCY CODE

   A.    GENERAL.  Under the Bankruptcy Code, actions by creditors to collect
         prepetition indebtedness are stayed and other contractual obligations
         may not be enforced against either the Corporation or Columbia
         Transmission.  As debtors-in-possession, both the Corporation and
         Columbia Transmission have the right, subject to Bankruptcy Court
         approval and certain other limitations, to assume or reject executory
         contracts and unexpired leases.  In this context, "rejection" means
         that the  debtor companies are relieved from their obligations to
         perform further under the contract or lease but are subject to a claim
         for damages for the breach thereof.  Any claims for damages resulting
         from rejection are treated as general unsecured claims in the
         reorganization.  The parties affected by these rejections may file
         claims with the Bankruptcy Court in accordance with bankruptcy
         procedures.  Prepetition claims which were contingent or unliquidated
         at the commencement of the Chapter 11 proceeding are generally
         allowable against the debtor-in-possession in amounts fixed by the
         Bankruptcy Court.  Substantially all liabilities as of the petition
         date are subject to  resolution under plans of reorganization to be
         approved by the  Bankruptcy Court  after submission to any required
         vote by affected parties.  The Corporation's reorganization plan also
         requires approval by the Securities and Exchange Commission (SEC)
         under the Public Utility Holding Company Act of 1935.

   B.    COLUMBIA TRANSMISSION'S PLAN OF REORGANIZATION.  The Corporation's and
         Columbia Transmission's discussions with the Official Committee of
         Unsecured Creditors of Columbia Transmission (Columbia Transmission
         Creditors' Committee) to negotiate a reorganization plan for Columbia
         Transmission and expedite emergence from Chapter 11 proceedings had
         been largely unsuccessful.  Therefore, on January 18, 1994, Columbia
         Transmission filed, with the Corporation as cosponsor, a
         reorganization plan (plan) and a disclosure statement, for
         consideration by its creditors and other interested parties.  The
         plan, which management believes is fair and equitable, proposes to pay
         100 percent for all priority, administrative and secured claims and
         offers various classes of general unsecured creditors, including
         producers whose gas





                                        63
<PAGE>   64
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         contracts were rejected by Columbia Transmission, between 80 and 100
         percent of Columbia Transmission's estimates of their allowable
         claims.  The $3.3 billion total distribution proposed in Columbia
         Transmission's plan is based on an estimated value for Columbia
         Transmission of $3.1 billion and includes significant financial
         contributions by the Corporation.  The plan is premised on a proposed
         omnibus settlement whereby the Corporation would settle the
         Intercompany Complaint (see page 65, C. Prepetition Obligations) and
         facilitate Columbia Transmission's reorganization by (i) accepting the
         value of the Corporation's secured claims against Columbia
         Transmission in the form of secured debt and equity securities of
         Columbia Transmission, and (ii) ensuring the cash (or at the option of
         the Corporation cash and $100 million market value of the
         Corporation's common stock) necessary to bring the aggregate
         distribution to $3.3 billion.  Creditors, other than the Corporation,
         would share in distributions of over $1.2 billion in cash.  In
         addition, the Corporation would consent to the reorganized Columbia
         Transmission's assumption of responsibility for public environmental
         enforcement agency claims so that the recoveries of the other
         creditors would not, with minor exceptions, be diminished by the
         environmental liabilities of Columbia Transmission's estate.

         The plan provides that Columbia Transmission will remain a
         wholly-owned subsidiary of the Corporation, will continue to offer an
         array of competitive transportation and storage services, and will
         retain ownership of its 18,800-mile pipeline network and related
         facilities.

         Columbia Transmission's proposed business solution will offer to
         producers, whose gas supply contracts were rejected or who have
         prepetition claims under those contracts, individual, specific
         settlements of the producers' claims that are based upon uniform
         assumptions and principles and which, in the view of Columbia
         Transmission's management, are fair and reasonable settlement values.
         These specific settlement proposals are being developed and will be
         filed as an adjunct to the plan.  Columbia Transmission estimates that
         aggregate distributions to producers under the plan would come to
         approximately $900 million.

         In general, the plan provides for immediate cash payment in full to
         all priority claims, all secured claims held other than by the
         Corporation, trust fund claims, administrative expenses and unsecured
         claims of $50,000 or less.  The Corporation's secured claims will be
         satisfied in full with new secured debt and equity securities to be
         issued by the reorganized Columbia Transmission.  Unsecured claims
         between $50,000 and $250,000 would receive 95 percent of their allowed
         claims in cash.   All other unsecured claims, including the
         Corporation's unsecured debt and producer contract rejection claims,
         would receive between 80 and 100 percent of their allowed claims based
         on current projections.  With respect to some of the classes of
         creditors, the treatment described above depends on the acceptance of
         the plan by the relevant class.  At this time, no creditors have
         agreed to any of the proposed plan's provisions, and the ultimate
         confirmed plan of reorganization could be materially different from
         this initial filing.

         Although Columbia Transmission's plan utilizes June 30, 1994, as an
         assumed date of emergence from bankruptcy, the actual date of
         emergence will depend on the time required to complete the bankruptcy
         process and obtain necessary creditor, judicial and regulatory
         approvals.  As part of its filing with the Bankruptcy Court, Columbia
         Transmission requested that the court defer scheduling required
         proceedings on the plan and related disclosure statement in order to
         permit discussions of the plan, including the settlements proposed
         therein, with Columbia Transmission's creditors, official committees
         and other interested parties.

         Under bankruptcy procedures, after Columbia Transmission's disclosure
         statement has been approved by the Bankruptcy Court, the disclosure
         statement and the reorganization plan will be sent to the company's
         creditors for voting.

         The Corporation intends to file a plan for its reorganization which
         will be consistent with the financial aspects and structure of
         Columbia Transmission's proposed plan of reorganization.  Both plans
         will be





                                         64
<PAGE>   65
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         subject to a lengthy review and approval process, including SEC
         approval, and obtaining adequate financing.

         Implementation of Columbia Transmission's plan, and the levels and
         timing of distributions to its creditors, are subject to a number of
         risk factors which could materially impact their outcome.  The plan
         sets forth numerous conditions to its confirmation and consummation.
         The failure to satisfy these conditions in accordance with the terms
         of the plan would have a material adverse effect on the outcome of
         Columbia Transmission's bankruptcy and on the Corporation. These
         conditions include, among others, the confirmation of a reorganization
         plan for the Corporation, the receipt of necessary approvals for the
         implementation of Columbia Transmission's plan and the recovery of
         regulatory and tax benefits which are fundamental to the plan's
         viability.  Both companies anticipate emerging from bankruptcy at the
         same time.  The provisions of the reorganization plans of either
         Columbia Transmission or the Corporation that are ultimately
         implemented could be materially different from this initial filing for
         Columbia Transmission and have a material adverse effect on the
         Corporation and its subsidiaries and on the rights of shareholders and
         holders of debt and other obligations.

   C.    PREPETITION OBLIGATIONS.  Columbia Transmission's prepetition
         obligations include secured and unsecured debt payable to the
         Corporation, estimated supplier obligations, estimated rate refunds,
         accrued taxes and other trade payables and liabilities.  Prepetition
         obligations of the Corporation primarily represent debentures, bank
         loans and commercial paper outstanding on the filing date together
         with accrued interest to that date.  A substantial amount of Columbia
         Transmission's liabilities subject to Chapter 11 proceedings relate to
         amounts owed to the Corporation.  Columbia Transmission's borrowings
         have been funded by the Corporation on a secured basis since June 1985
         and are secured by mortgages and a cash collateral order approved by
         the Bankruptcy Court. On the petition date, the principal amount of
         the First Mortgage Bonds outstanding was $930.4 million.  Prepetition
         and postpetition interest on secured debt owed by Columbia
         Transmission to the Corporation is $346.4 million at December 31,
         1993.  In addition to these secured claims, the Corporation has an
         unsecured claim against Columbia Transmission of $351 million in
         installment notes issued prior to 1985 and accrued interest to the
         petition date.

         On March 19, 1992, the Columbia Transmission Creditors' Committee
         filed a complaint (Intercompany Complaint) with the Bankruptcy Court
         alleging that the $1.7 billion of Columbia Transmission's secured and
         unsecured debt securities held by the Corporation should be
         recharacterized as capital contributions (rather than loans) and
         equitably subordinated to the claims of Columbia Transmission's other
         creditors.  The Intercompany Complaint also challenges interest and
         dividend payments made by Columbia Transmission to the Corporation of
         approximately $500 million for the period from 1988 to the petition
         date and the 1990 property transfer from Columbia Transmission to
         Columbia Natural Resources, Inc. (CNR) as an alleged fraudulent
         transfer.  Based on the SEC standardized measurement procedures, CNR's
         properties had a reserve value of approximately $387 million as of
         December 31, 1993, a significant portion of which is attributable to
         the transfer from Columbia Transmission.  In May 1992, Columbia
         Transmission Creditors' Committee filed with the U.S.  District Court
         a motion for a jury trial and to move the Intercompany Complaint from
         the Bankruptcy Court to the U. S. District Court.  This motion was
         denied and subsequently appealed to the Third Circuit Court of Appeals
         (Third Circuit).  In June 1992, the Corporation filed a motion with
         the Bankruptcy Court seeking dismissal of, or summary judgment on,
         principal portions of the Intercompany Complaint. On August 20, 1993,
         the Third Circuit denied Columbia Transmission Creditors' Committee's
         appeal, allowing the Bankruptcy Court to consider the merits of the
         Intercompany Complaint and act upon the Corporation's June 1992 motion
         for summary judgment.  The Bankruptcy Court has not acted on the
         Corporation's motion for summary judgment, but tentatively scheduled a
         trial on the Intercompany Complaint to begin June 13, 1994.
         Management believes that the Intercompany Complaint is without merit;
         however, the ultimate outcome of these issues is uncertain at this
         stage of the proceedings.





                                     65

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         Discussions with Columbia Transmission's creditors in an attempt to
         establish the value of the estate and to resolve the matters raised in
         the Intercompany Complaint are ongoing.  Since the standing and value
         of the Corporation's debt investment in Columbia Transmission is
         crucial to the determination of the value of the Corporation's estate,
         the Corporation's reorganization could be affected by the ultimate
         outcome of the Intercompany Complaint.

         The Internal Revenue Service (IRS) filed identical claims of $553.7
         million against both debtor companies and the consolidated Columbia
         Gas System for tax deficiencies, interest and penalties for the years
         1983-1990.  Negotiations with IRS representatives have resulted in a
         settlement on all of the issues included in the IRS claims.  This
         settlement has been documented in a written closing agreement and
         filed with the Joint Committee on Taxation of the U.S. Congress for
         formal approval. The IRS settlement also requires Bankruptcy Court
         approval.  Recording the IRS settlement reduced 1993 net income by
         $44.3 million.

         Columbia Transmission has recorded liabilities of approximately $1.2
         billion to reflect the estimated effects of its above-market producer
         contracts and estimated supplier obligations associated with pricing
         disputes and take-or-pay obligations for historical periods.  With
         Bankruptcy Court approval, Columbia Transmission rejected more than
         4,800 above-market gas purchase contracts with producers.  The
         producers whose gas purchase contracts were rejected filed claims for
         damages that, after being adjusted for duplicative and other erroneous
         claims, are in excess of $13 billion.  The Bankruptcy Court approved
         the appointment of a claims mediator in 1992 to implement a claims
         estimation procedure related to the rejected above-market producer
         contracts and other producer claims.  The mediator held hearings on
         generic issues and various estimation methodologies and discovery
         matters during 1993.  Columbia Transmission anticipates that the
         mediator may issue recommended determinations during the second
         quarter of 1994 which, under the Bankruptcy Court-approved estimation
         procedure, are expected to provide the basis for a recalculation of
         producer contract rejection claims.  In Columbia Transmission's
         judgment, the positions taken by all producers before the claims
         mediator and the evidence presented demonstrate that the total level
         of allowable contract rejection claims, generically determined, will
         not exceed 1/10th of the $13 billion asserted in the claims as filed
         and is likely to be between $600 million and $950 million.  The
         acceptance of certain positions advanced by Columbia Transmission on
         the evidence of record, as well as Columbia Transmission's as yet
         unheard defenses, could decrease substantially this range of possible
         aggregate outcomes.  Resolution of the contract-specific issues not
         yet presented could increase or decrease individual claims materially
         but should not significantly alter the range of possible aggregate
         outcomes.

         The resolution of these issues can significantly influence future
         reported financial results.  Accounting standards require that as
         claim amounts are allowed by the Bankruptcy Court, the full amount of
         the allowed claim must be recorded.  This could result in liabilities
         being recorded which bear little relationship to the amounts
         ultimately required to be paid in settlement of those claims and could
         conceivably exceed the Corporation's total investment in Columbia
         Transmission.  Any such distortion would not be corrected until final
         plans of reorganization are approved for the Corporation and Columbia
         Transmission.

         Regarding claims made by pipeline suppliers, on September 13, 1993,
         the Bankruptcy Court approved an agreement between Columbia
         Transmission and Texas Eastern Corporation (Texas Eastern) and the
         settlement of related claims.  Under the terms of this agreement,
         Columbia Transmission will collect $30 million in refunds from Texas
         Eastern and all claims filed by Texas Eastern against Columbia
         Transmission, totalling $672 million, will be withdrawn.  In November
         1993, the Bankruptcy Court approved a settlement between Columbia
         Transmission and Tennessee Gas Pipe Line Company (Tennessee).  This
         agreement provides for Columbia Transmission's assumption of certain
         contracts, the termination of certain other contracts that are no
         longer necessary for Columbia Transmission's operations, and payment
         to Tennessee of approximately $42 million in consideration for
         Tennessee's substantial reduction of its major transportation
         contracts with Columbia Transmission.  On January 11, 1994, Columbia
         Transmission and Tennessee made a filing with the FERC to approve the
         settlement.  Columbia Transmission expects to ultimately recover the
         costs and fees associated with the assumption and termination of these
         contracts under





                                    66
<PAGE>   67
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         Order 636.  The Tennessee settlement agreement is conditioned upon
         this recoverability.  These settlements resolve a significant portion
         of the pipeline supplier claims against Columbia Transmission.

         The Pension Benefit Guaranty Corporation (PBGC) filed claims of $150
         million against both the Corporation and Columbia Transmission
         alleging that if the retirement plan had been terminated by March 31,
         1992, it would have been underfunded.  Management believes that the
         claims made by the PBGC are inappropriate and in error since the
         Bankruptcy Court has approved continued operation of the retirement
         plan, required annual contributions are being made, there is no
         intention to terminate the plan and the plan is not underfunded.
         Management further believes that the PBGC's claim can be resolved
         without any financial consequences to the Corporation or Columbia
         Transmission.  On January 29, 1993, the PBGC confirmed that while it
         remains confident that issues regarding its claims can be resolved by
         mutual agreement, the PBGC has decided not to proceed further with
         settlement negotiations regarding withdrawal of its claims at the
         present time due to the uncertainties associated with the bankruptcy
         proceedings.  At December 31, 1993, the date of the latest actuarial
         valuation, plan assets exceeded the accumulated benefit obligations by
         $166.5 million.

<PAGE>   69
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

   D.    PAYMENT OF DIVIDENDS AND DEBT SERVICE.  The Corporation's Board of
         Directors suspended the payment of dividends on the Corporation's
         common stock on June 19, 1991.  The Corporation also discontinued
         payments related to debt service.  Columbia Transmission suspended
         dividend, interest and debt payments to the Corporation.  The
         Corporation and Columbia Transmission have also suspended the payment
         of most other prepetition obligations.  Management cannot predict at
         this time when or whether any financial restructuring plans will be
         approved or what provisions, if any, such plans would contain as
         related to the resumption of dividends, debt service and other
         payments.

   E.    INTEREST EXPENSE.  Interest expense of the Corporation is not being
         accrued during bankruptcy, but a calculation of interest is included
         in a footnote on the Statements of Consolidated Income and
         Consolidated Balance Sheets.  Such interest has been calculated based
         on management's interpretation of the contractual arrangements which
         govern the various debt instruments the Corporation has outstanding
         exclusive of any redemption premiums.  The Official Committee of
         Unsecured Creditors of the Corporation has asserted claims for
         interest which exceed disclosed amounts by approximately $40 million
         at December 31, 1993. There are several factors to be considered in
         making these calculations that are subject to uncertainty as to their
         ultimate outcome in the bankruptcy proceeding, including the interest
         rates and method of calculation to be applied to overdue payments of
         principal and interest.  In addition, the committee has asserted that
         approximately $110 million of redemption premiums should be paid on
         high cost debt instruments.

   F.    SECURITY HOLDER LITIGATION.  After the announcement on June 19, 1991,
         regarding the Corporation's probable charge to second quarter earnings
         and the suspension of its dividend, 17 complaints including purported
         class actions were filed against the Corporation and its directors and
         certain officers of the debtor companies in the U.S. District Court of
         Delaware.  The actions, which generally allege violations of certain
         anti-fraud provisions of the Securities Act of 1933 and the Securities
         Exchange Act of 1934, have been consolidated.  In addition, three
         derivative actions were filed in the Court of Chancery in and for New
         Castle County (Delaware) alleging that directors breached their
         fiduciary duties.  These suits have been stayed by either the
         Bankruptcy Court filing or by stipulation of the parties.  While the
         Corporation believes that it has meritorious defenses to these
         actions, the outcome is uncertain at this time.

   G.    CUSTOMER RECOUPMENT RIGHTS.  During the fourth quarter of 1993,
         various customers of Columbia Transmission filed motions with the
         Bankruptcy Court seeking authority to exercise alleged recoupment and
         setoff rights, whereby they would be permitted to reduce amounts owed
         to Columbia Transmission against refunds owed to the customers by
         Columbia Transmission, including amounts which were not otherwise
         payable in full under the July 1993 Third Circuit decision discussed
         below, all customer refunds under the 1990 rate case settlement and
         miscellaneous refunds not otherwise payable in full to them.
         Customers are alleging that they have recoupment and setoff rights of
         approximately $83 million at December 31, 1993.

         On October 20, 1993, the Bankruptcy Court approved an interim
         settlement under which customers continued to pay Columbia
         Transmission for FERC-authorized services at authorized rates, and
         Columbia Transmission has agreed to grant these customers a priority
         claim to the extent the Bankruptcy Court finds them entitled to
         recoupment rights.  In January 1994, the Bankruptcy Court issued a
         procedural order whereby other customers would be permitted to file
         recoupment and setoff motions by February 18, 1994, with a trial on
         all such motions scheduled for June 1994.

   H.    CUSTOMER REFUNDS.  In July 1993, the Third Circuit overturned most of
         a U.S. District Court ruling and affirmed an earlier Bankruptcy Court
         decision that refunds Columbia Transmission received from upstream
         pipelines, as well as the Gas Research Institute (GRI) surcharge
         payments it collected from customers, are held in trust, by Columbia
         Transmission, for those customers and the GRI and are not part of
         Columbia Transmission's estate.  In August 1993, the Third Circuit
         denied the Columbia Transmission Creditors' Committee's request for a
         rehearing.  In February 1994, the Supreme Court denied petitions for
         review of the Third Circuit decision.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)


         Under the Third Circuit ruling, approximately $173 million in refunds
         that Columbia Transmission has received, or expects to receive
         postpetition from upstream pipelines and GRI surcharges collected,
         should be passed through to the customers and to the GRI.  In
         addition, the Third Circuit determined that $35 million in upstream
         pipeline refunds and GRI surcharges, which Columbia Transmission
         collected prior to filing Chapter 11 while received in trust, were
         subject to the "lowest intermediate cash balance test" (the amount
         remaining in trust at the time of bankruptcy) and should be
         distributed on a pro rata basis to the customers and to the GRI to the
         extent of Columbia Transmission's $3.3 million cash balance on July
         31, 1991.  The Third Circuit affirmed another part of the U.S.
         District Court's decision and held that approximately $16 million that
         Columbia Transmission owes upstream suppliers, for gas purchased and
         transportation services received prior to its bankruptcy filing, is
         ordinary unsecured debt which must be discharged in the bankruptcy
         process.

         On February 10, 1994, the U.S. District Court issued an order for the
         Bankruptcy Court to pursue further proceedings in accordance with the
         Third Circuit's refund decision directing the pass-through of these
         refunds.  At a hearing on December 29, 1993, the Bankruptcy Court
         observed that the FERC should determine whether customers are entitled
         to the actual interest earned on refunds being held by Columbia
         Transmission or the higher FERC-prescribed interest rate.  On February
         18, 1994, Columbia Transmission filed a motion with the FERC for
         determination of the interest issue.  Columbia Transmission will ask
         the Bankruptcy Court for implementation of the mandate.  Columbia
         Transmission will also have to file with the FERC to reimplement its
         flow-through of Order Nos. 500/528 refunds from its pipeline
         suppliers, which represent the majority of the refunds at issue.  It
         is anticipated that Columbia Transmission will recommence the
         flow-through of the upstream pipeline refunds in 1994.

         Total customer claims in Columbia Transmission's bankruptcy
         proceedings relating to, or arising from, Columbia Transmission's
         contracts with its customers for sales, transportation, gas storage
         and similar services and other miscellaneous claims represent about
         450 claims for a total of approximately $550 million as filed, plus a
         potentially substantial sum filed in undetermined amounts.  Columbia
         Transmission successfully resolved a significant portion of these
         customers claims.  Not resolved are customer claims that total
         approximately $113 million at December 31, 1993, that seek to protect
         rights associated with any prepetition revenues collected subject to
         refund in general rate filings and purchased gas adjustment filings,
         including matters subject to court appeals.  In addition, the claims
         filed in undetermined amounts, which potentially could be significant,
         still remain to be resolved.  In October 1993, approximately $160
         million was refunded to customers by Columbia Transmission reflecting
         the terms of a settlement of a 1991 rate case approved by the
         Bankruptcy Court in July 1993.  Bankruptcy Court approval for a 1990
         rate case settlement for rates in effect from November 1, 1990 through
         November 30, 1991 was deferred pending the decision by the Third
         Circuit regarding the flow- through of certain refunds.  Appropriate
         reserves for rate refund liabilities have been recorded for these
         matters to reflect management's judgment of the ultimate outcome of
         the proceedings.

   I.    REORGANIZATION ITEMS.  During 1993, 1992 and 1991 the Corporation and
         Columbia Transmission have earned interest income on cash accumulated
         from the suspension of payments related to prepetition liabilities and
         incurred expenses associated with professional fees and other related
         services, as detailed below:

3.  REGULATORY MATTERS

   A.    Columbia Transmission has collected revenues from its customers
         associated with the pass-through of upstream pipeline supplier take-
         or-pay and contract reformation costs under FERC Order Nos. 500 and
         528.  Certain customers have challenged recovery of such costs which
         totals $160 million, (excluding interest) net of amounts to be
         refunded, on the basis that a 1985 rate settlement precludes
         collection.  The FERC has consistently denied the customers'
         assertions and appeals have been filed with the U.S. Court of Appeals,
         D.C. Circuit.  Management continues to believe these challenges are
         without merit and the FERC orders, which support collection of these
         costs, will ultimately be upheld.

   B.    In April 1992, the FERC issued Order 636, its final rule on Pipeline
         Service Obligations and Equality of Transportation Services by
         Pipelines.  This order fundamentally changes the role of pipelines
         from providing a merchant function to one in which they perform
         principally as transporters of gas that distribution companies and end
         users purchase directly from producers and other suppliers.

         While Order 636 provided that pipelines may recover all prudently
         incurred costs resulting from the transition to Order 636, the FERC
         stated that filings to recover such costs should not be made until a
         pipeline's service restructuring proposal, that identifies various
         transition costs, has been approved.  With respect to gas supply
         realignment costs, costs associated with reforming or terminating
         above-market price supply contracts, Columbia Transmission noted in
         its filing that the majority of such costs on its system will be
         determined in the context of the bankruptcy proceedings regarding the
         treatment of producer





                                       71

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         contract rejection costs.  The company stated that the ultimate level
         of such costs is uncertain and that recovery would be pursued in
         future filings with the FERC.

         In 1993, the FERC issued a series of orders on the restructuring
         proposals and on September 29, 1993, the FERC issued an order which
         allowed Columbia Transmission and Columbia Gulf to implement
         restructured services on November 1, 1993. While confirming its
         initial ruling regarding the ineligibility for recovery of producer
         contract rejection costs as gas supply realignment or Order Nos.
         500/528 costs, the  FERC did rule that Columbia Transmission could
         seek to recover a small portion of the contract rejection costs that
         had earlier been ruled to be unrecoverable.  The FERC also agreed to
         waive a nine-month time limit on Columbia Transmission's ability to
         seek recovery of unrecovered purchased gas costs to the extent the
         costs resulted from contracts that are currently in litigation,
         including bankruptcy litigation.  Approximately $60 million in
         unrecovered purchased gas costs were outstanding at December 31, 1993,
         in addition to approximately $140 million of prepetition unrecovered
         purchased gas costs that have not been paid due to the bankruptcy
         filing.

         The FERC affirmed that Columbia Transmission could maintain recovery
         of gathering costs through its gathering and other transportation
         rates at least until the filing of a general rate case and approved a
         separate charge applicable to product extraction activities.
         Management continues to evaluate long-term plans for these gathering
         facilities ($63.3 million at December 31, 1993).

         Subject to review in connection with periodic rate filings, the FERC
         approved Columbia Transmission's proposal to continue to recover costs
         associated with retained upstream pipeline contracts through its
         demand rates.  Recovery of such costs would be subject to review and
         approval in semiannual limited rate filings.  Columbia Transmission
         has reached settlements that will eliminate approximately half of the
         annual cost of these contracts and is continuing its efforts to
         negotiate a mutually agreeable termination of the remainder of the
         contracts.

         The FERC also addressed Columbia Transmission's ability to recover
         costs associated with upstream pipeline contracts.  Columbia
         Transmission currently holds firm transportation agreements with
         certain pipeline companies that historically have been used to deliver
         gas to Columbia Transmission.  These contracts have remaining terms of
         various lengths and require the payment of monthly reservation fees
         whether or not the capacity is utilized.  Under Order 636, downstream
         pipelines such as Columbia Transmission are required to offer to
         assign most of their firm upstream capacity to their customers.
         Columbia Transmission's annual demand charge commitments on these
         upstream nonaffiliated pipelines was approximately $108 million;
         however, assignments of certain of these contracts by Columbia
         Transmission to its customers in conjunction with service
         restructuring under Order 636 have reduced this amount to less than
         $74 million.  The total commitment for demand charges after November
         1, 1993, is approximately $421 million on an undiscounted basis,
         excluding any mitigating effect of the pipelines marketing the
         capacity to others.

         Columbia Transmission's strategy has been to assume all upstream
         pipeline contracts that can be directly assigned to its customers or
         need to be retained by Columbia Transmission for operational reasons
         and negotiate exit fees for other upstream contracts.  The FERC ruling
         in the Order 636 proceedings permits recovery of these exit fees
         through rates, provided that Columbia Transmission can show that they
         are prudently incurred.  Columbia Transmission retains the option of
         rejecting such contracts in its bankruptcy proceedings, if appropriate
         exit fees cannot be negotiated.   The financial statements reflect a
         $130 million liability and offsetting receivable for the exit fee
         issue; however, the ultimate cost could vary depending on the outcome
         of ongoing discussions with the affected pipelines.

         Several settlements with upstream pipelines have been concluded.  In
         1993, the Bankruptcy Court approved





                                       72
<PAGE>   73
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         settlements between Columbia Transmission and Texas Eastern
         Transmission Corporation, Panhandle Eastern Pipe Line Company and
         Texas Gas Transmission Corporation which provide for assumption of
         certain contracts and termination of others.  None of these
         settlements required Columbia Transmission to pay an exit fee to the
         upstream pipeline.

         One type of transition cost which the FERC acknowledged would be
         eligible for recovery consideration is "stranded costs", which are the
         costs of a pipeline's assets previously used to provide bundled sales
         service in the pre-Order 636 era, that are unsubscribed in the Order
         636 environment.  Columbia Gulf has several pipelines and related
         facilities that are not fully subscribed to under Order 636.  Certain
         facilities south of Rayne, Louisiana, (primarily in the offshore Gulf
         of Mexico area) are being evaluated; however, management has not
         identified any stranded facilities at this time and the outcome of
         these evaluations is uncertain.  Dependent upon the results of such
         evaluation, charges to income could be required.  The net book value
         of the facilities under study was approximately $40 million at
         December 31, 1993. It is management's view that any costs associated
         with these facilities will be fully recoverable through rates.

         As part of its September 29, 1993 order on Columbia Transmission's and
         Columbia Gulf's Order 636 compliance filings, the FERC initiated a
         proceeding concerning Columbia Gulf's transportation service to
         Columbia Transmission.  Columbia Gulf was directed to show cause as to
         why it has not filed for abandonment to reduce capacity and service to
         Columbia Transmission under the required FERC authorization under
         Section 7(b) of the Natural Gas Act.  Columbia Gulf responded to the
         show cause order on December 22, 1993.  Management does not believe an
         abandonment filing was necessary and does not expect the resolution of
         this issue to have a material adverse effect on the Corporation's
         financial position.

   C.    On January 12, 1994, the FERC granted requests for rehearing of prior
         orders approving settlements between Columbia Transmission and four of
         its upstream pipeline suppliers relating to those suppliers' direct
         billings to Columbia Transmission in the mid-1980s of
         production-related FERC Order No. 94 (Order 94) costs.  The rehearing
         orders find that the settlements must be rejected because they are
         expressly contingent upon Columbia Transmission's recovery of the
         Order 94 settlement payments from its customers, and that Columbia
         Transmission's 1985 PGA Settlement essentially bars such recovery.
         However, the orders also hold that these pipelines are not entitled to
         bill any Order 94 charges to Columbia Transmission, and ordered these
         upstream pipelines to refund the principal portion of all Order 94
         collections from Columbia Transmission, but waived any requirements
         that these pipelines pay interest on the refunds.  Since Columbia
         Transmission has been reflecting the interest income on these refunds
         since 1990, the effect of these orders led to a $19.5 million
         reduction in interest income in 1993.  Columbia Transmission has
         sought rehearing and, if necessary, will seek court review of these
         orders.  It is expected that pipeline suppliers will also request a
         rehearing arguing their rights to re-bill such charges to Columbia
         Transmission.  The ultimate outcome of this issue is uncertain at this
         time and could impact future operating results depending upon the
         results of these regulatory and court reviews.

4.  ACCOUNTING CHANGES

   A.    In the fourth quarter of 1991, the Corporation adopted SFAS No. 106,
         "Employers' Accounting for Postretirement Benefits Other Than
         Pensions" (OPEB), retroactive to January 1, 1991.  This method of
         accounting for postretirement benefits accrues the actuarially
         determined costs for life insurance and medical benefits ratably from
         the date an employee becomes eligible for such benefits.  The
         Corporation's subsidiaries previously expensed these costs as cash
         payments were made.  As permitted under SFAS No. 106, the subsidiaries
         elected to record the full amount of their estimated accumulated
         postretirement benefits obligation other than pensions of $223.8
         million. These obligations represent the actuarial present value of
         the postretirement benefits to be paid to current employees and
         retirees based on services rendered.

         The present value of the postretirement benefit obligation to be paid
         to current and retired employees for all the distribution subsidiaries
         amounts to approximately $143 million as of December 31, 1993.  Of
         this amount, $138.1 million has been deferred as a regulatory asset
         pending anticipated recovery through rates in various jurisdictions.
         The Emerging Issues Task Force (EITF) of the Financial Accounting
         Standards Board issued guidelines  establishing criteria for recording
         such a regulatory asset, including a requirement for collection of
         accrual basis expense in rates and recovery of the transition
         obligation within approximately 20 years.  These criteria are not
         necessarily being adopted by the public utility commissions regulating
         the distribution subsidiaries.  Differences in requirements between
         the accounting rules and the rate making decisions ultimately adopted
         can result in a writedown of some of this regulatory asset.

         The distribution subsidiaries, as well as the Corporation's other
         operating companies, have implemented cost-management measures
         designed to reduce their OPEB obligations.  In addition to other
         measures, employees will be required to share a portion of their
         postretirement health benefit costs and guidelines have been
         established redefining years of service requirements before an
         employee is eligible for retiree health benefits.  Other cost-saving
         plans are being reviewed for consideration in an ongoing effort to
         effectively manage OPEB costs.

         The regulatory commission in Ohio issued a final order in February,
         1993 in a generic rate investigation regarding recovery of
         postretirement benefit costs.  The commission's order provides
         utilities the opportunity to fully recover prudently incurred
         postretirement costs on an accrual basis.  Amounts in excess of
         pay-as-you-go costs may continue to be deferred until rate recovery
         begins.  The amount of the Columbia Gas of Ohio regulatory asset in
         the accompanying balance sheet was $85.6 million as of December 31,
         1993.

         In March 1993, the Pennsylvania PUC stated in a proposed policy
         statement that any utility in its jurisdiction meeting certain
         conditions may seek formal PUC approval to record a regulatory asset
         equal to the difference between its current rate recognition of
         postretirement benefit costs and its accrued liability for such
         expenses.  The amounts recorded will be subject to recovery in future
         rate proceedings to the extent that such costs are prudently incurred
         and certain conditions are met, such as dedicated funding of
         postretirement costs in excess of the pay-as-you-go level.  Columbia
         Gas of Pennsylvania's (CPA) petition to maintain the postretirement
         benefit deferred regulatory asset until rate recovery begins was
         granted in December, 1993.  This order gave CPA the permission to
         recover transition costs over 20 years.  At December 31, 1993, the
         carrying value of CPA's regulatory asset was approximately $33.1
         million.

         The Kentucky state commission has indicated that the rate treatment of
         accrued postretirement benefits will be addressed on a company-
         by-company basis.  Management believes Columbia Gas of Kentucky (CKY)
         will ultimately obtain recovery authorization based on a recent
         commission rate order for another utility, holding that recovery of
         these costs on an accrual basis better reflects the true cost of
         providing service to current customers.  CKY will continue to defer
         its postretirement benefit costs in excess of the pay-as-you-go
         amount, pending the filing of its next general rate case which is
         currently scheduled for mid-1994.  At December 31, 1993, the carrying
         value of CKY's regulatory asset was approximately $9.8 million.

         Commonwealth Gas Services (COS) placed interim rates into effect June
         1, 1993, subject to refund, which included recovery of accrued OPEB
         costs.  Indications from the Virginia State Corporation Commission
         (VSCC) are that the costs will be deemed prudent and recoverable
         according to the commission's 1992 generic order addressing
         postretirement costs.  As a result of the recovery of transition costs
         over a period of 40 years, the EITF guidelines required COS to expense
         $4.2 million in 1992.

         Columbia Gas of Maryland's (CMD) general rate case settlement,
         effective October 1993, allows CMD to include in rates the full amount
         of accrued postretirement benefit costs as well as the recovery of the
         transition obligation over 20 years.

         Although proceedings in certain state jurisdictions have yet to be
         finalized, based on currently available information, management
         believes rate recovery mechanisms will be adopted that permit
         continued regulatory asset treatment in accordance with recent EITF
         guidelines.

   B.    In February 1992, the Financial Accounting Standards Board issued SFAS
         No. 109, "Accounting for Income Taxes."  The Corporation adopted SFAS
         No. 109 in the fourth quarter of 1992, retroactive to January 1, 1992.
         This Statement supersedes SFAS No. 96, "Accounting for Income Taxes,"
         which was adopted by the Corporation in 1991 and improved earnings by
         $170 million.  SFAS No. 109 changes the criteria for recognition and
         measurement of deferred tax assets and reduces complexity.  The
         adoption of SFAS No. 109 had no impact on the Corporation's financial
         statements.

   C.    In November 1992, the Financial Accounting Standards Board issued SFAS
         No. 112, "Employers' Accounting for Postemployment Benefits." This
         Statement requires employers to recognize any obligation which exists
         to provide benefits to former or inactive employees after employment,
         but before retirement.  Such benefits include, but are not limited to,
         salary continuation, supplemental unemployment, severance, disability
         (including workers' compensation), job training, counseling, and
         continuation of benefits such as health care and life insurance
         coverage.

         This Statement will be effective for fiscal years beginning after
         December 15, 1993, and the Corporation plans to adopt the Statement on
         January 1, 1994.  Based on the facts and circumstances known today,
         the total obligation to the Corporation and its subsidiaries will be
         approximately $8.8 million.  Of this amount, approximately $5.4
         million will be expensed upon adoption.  The remaining $3.4 million
         will be deferred by certain of the distribution subsidiaries as a
         regulatory asset pending rate recovery from the various state
         commissions.

6.  SALE OF SUBSIDIARIES

   A.    The sale of Columbia Gas of New York, Inc. to New York State Electric
         & Gas Corporation was completed on April 5, 1991, and provided an
         increase to net income of $9.2 million.  The total price was $57.5
         million including $39.2 million for the 328,000 outstanding shares of
         common stock and $18.3 million for the outstanding debt.

   B.    The sale of Columbia Gas Development of Canada Ltd. (Columbia Canada),
         a wholly-owned Canadian oil and gas exploration and production
         subsidiary, to Anderson Exploration, Ltd. was effective as of December
         31, 1991.

         The sales price for Columbia Canada was $94.8 million.   Of this
         amount, $27.7 million was placed in escrow as security for certain
         post-closing obligations of the Corporation including indemnification
         for potential losses arising from litigation involving Columbia
         Canada.  The Corporation expects to receive all or substantially all
         of the escrow account when the litigation is concluded.  Upon
         emergence from bankruptcy, the Corporation is obligated to deposit
         into an escrow account an additional $25 million (Canadian).  If after
         emergence from bankruptcy, the Corporation maintains an investment
         grade bond rating for a six-month period, the additional deposit would
         be

         returned.  Also, the Corporation has the right to provide a letter of
         credit in place of the cash deposit.  As of December 31, 1993, $25.4
         million, including accrued interest, remains in escrow for potential
         losses arising from litigation.

7.  PENSION AND OTHER POSTRETIREMENT BENEFITS

         The Corporation has a trusteed, noncontributory pension plan which
         covers all regular employees, 21 years of age and older.  The plan
         provides defined benefits based on the highest three-year average
         annual compensation in the final five years of service and years of
         credited service.  It is the Corporation's funding policy to
         contribute to the plan based on a percentage of payroll, subject to
         the statutory minimum and maximum limits.

         The following table provides 1993-1991 pension cost components for the
         plan, along with additional relevant data:

         As of December 31, 1993, the assumptions for the discount rate and the

         percent and 5.5 percent, respectively.  The net effect of these

         The healthcare cost trend rate assumption significantly affects the
         amounts reported.  For example, a 1 percent increase in this rate
         would increase the accumulated postretirement benefit obligation by
         $19.0 million at December 31, 1993, and increase other postretirement
         costs by $3.7 million for the year.  The accumulated

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

         postretirement benefit obligations for 1993 and 1992 were calculated
         assuming healthcare cost trend rates starting at 12 percent and 16
         percent and decreasing to 5.5 percent and 6.5 percent, respectively,
         after approximately 25 years.

         The postretirement medical plans of the majority of the Corporation's
         subsidiaries are currently funded on a pay-as-you-go basis.  However,
         several subsidiaries have begun advanced funding as this benefit
         obligation is granted rate recovery.  A total of $16.9 million and
         $13.0 million were contributed to the various medical trusts in 1993
         and 1992, respectively.

         All of the Corporation's subsidiaries participate in funding for
         postretirement life insurance benefits utilizing a voluntary employee
         beneficiary association trust.  The Corporation's funding policy is to
         make annual contributions to this trust, subject to the statutory
         maximum tax-deductible limit.  Employee contributions are not
         required.

8.  LONG-TERM INCENTIVE PLAN

         The Corporation has a Long-Term Incentive Plan (Plan) which provides
         for the granting of nonqualified stock options, stock appreciation
         rights and contingent stock awards as determined by the Compensation
         Committee of the Board of Directors.  That committee also has the
         right to modify any outstanding award.  A total of 1,500,000 shares of
         the Corporation's authorized common stock was initially reserved for
         issuance under the Plan's provisions.  There were 363,415 shares
         remaining available for awards at December 31, 1993.

         Stock appreciation rights, which are granted in connection with
         certain nonqualified stock options, entitle the holders to receive
         stock, cash or a combination thereof equal to the excess market value
         over the grant price.

      In addition to the options, a contingent stock award of 4,110 shares was
      granted to a key executive in 1991 which remains outstanding at December
      31, 1993.

9.    DEFINED CONTRIBUTION (THRIFT) PLAN

      Eligible employees may participate in the Thrift Plan by contributing up
      to 16 percent of their monthly basic earnings to any one or more of
      several funds.  The Corporation's participating subsidiaries make
      matching contributions of 50 percent to 100 percent of deposits made by
      each of its participating employees up to 6 percent of basic earnings
      based upon the months of participation in the plan by each employee.  All
      employer matching contributions for participants under age 55 are
      invested in the fund holding common stock of the Corporation.
      Participants age 55 and older may invest employer contributions in any
      one or more of the several funds.  Employees are eligible for
      participation in the Thrift Plan after completing one year of service.

      In 1990, the Corporation established a Leveraged Employee Stock Ownership
      Plan (LESOP).  The LESOP was designed to pre-fund a portion of the
      matching obligation under the terms of the Thrift Plan and to utilize tax





                                       82
<PAGE>   83
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

      advantages afforded by the Internal Revenue Code.

      In October 1991, the Board of Directors of the Corporation authorized the
      termination of the LESOP subject to the approval of the Bankruptcy Court.
      It is anticipated that the termination will be part of the Corporation's
      plan of reorganization.  Upon termination, any shares of common stock of
      the Corporation remaining in the LESOP Trust account would be sold and
      the proceeds paid to the holders of debentures issued under the LESOP.
      Any unpaid balance due would become subject to the subordinate guarantee
      of the Corporation and become a claim to be resolved as part of the
      reorganization plan.  Based on recently issued guidance from the American
      Institute of Certified Public Accountants, it is anticipated the ultimate
      termination will not result in any charges to earnings, but will result
      in a reduction to capital of approximately $34.1 million based on a
      closing stock price of $25 3/8 on January 31, 1994.  As of December 31,
      1993, the LESOP suspense account held 1,416,155 shares.

      The participating subsidiaries ceased making contributions to the LESOP
      for debt service payments but continue to contribute to the Thrift Plan
      those amounts necessary to fulfill the matching obligations to
      participants.  Matching contributions to the Thrift Plan were $11.0
      million, $13.2 million and $8.6 million in 1993, 1992, and 1991,
      respectively.  Thrift Plan expenses were $11.0 million, $13.2 million and
      $17.9 million for 1993, 1992 and 1991, respectively.  The difference
      between matching contributions and expense for 1991 was attributable to
      the additional expenses required under the now suspended LESOP.

10.   DEBT OBLIGATIONS

      The Corporation's filing for protection under the Bankruptcy Code
      constituted an event of default under substantially all of its debt
      agreements.  Because payment of debt which existed at the filing date is
      suspended by the Bankruptcy Code, substantially all of the Corporation's
      debt, including short-term debt, has been classified as Liabilities
      Subject to Chapter 11 Proceedings.  In addition, payment of interest on
      prepetition debt is suspended, and no interest expense on such debt has
      been recorded since commencement of the bankruptcy proceedings.

      Following the Chapter 11 filing, the Corporation received approval from
      the Bankruptcy Court and the SEC, under the Public Utility Holding
      Company Act of 1935, for debtor-in-possession financing (the DIP
      Facility).  The DIP Facility is for up to $100 million and includes the
      availability of letters of credit of up to $50 million.  The DIP Facility
      was reduced by the Corporation from $275 million to $200 million on July
      10, 1992 and was reduced to the current level effective June 17, 1993.
      The Corporation has extended the DIP Facility to December 31, 1994.

      Two borrowing options are available to the Corporation under the DIP
      Facility.  The Corporation may borrow at the agent's alternative
      reference rate plus 1 percent or the Eurodollar rate plus 2 1/4 percent
      (for either 1, 2 or 3 months).  In addition to a commitment fee of 1/2 of
      1 percent per annum on the average daily unused amount of the facility,
      other fees have been paid to the lenders under the DIP Facility.

      Columbia Transmission also maintains a DIP Facility solely for the
      issuance of letters of credit for up to $25 million.  Columbia
      Transmission has extended its DIP Facility to December 31, 1995, to allow
      for letters of credit with terms for the full calendar year of 1995.

11.   DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

      The Corporation, effective December 31, 1992, adopted SFAS No. 107,
      "Disclosures about Fair Value of Financial Instruments."  The Statement
      extends existing fair value disclosure practices by requiring all
      entities to disclose the fair value of financial instruments, both assets
      and liabilities, recognized and not recognized in





                                       83
<PAGE>   84
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

      the Consolidated Balance Sheets, for which it is practicable to estimate
      fair value.  For purposes of this disclosure, the fair value of a
      financial instrument is the amount at which the instrument could be
      exchanged in a current transaction between willing parties, other than in
      a forced or liquidation sale.  Fair value may be based on quoted market
      prices for the same or similar financial instruments, or on valuation
      techniques such as the present value of estimated future cash flows using
      a discount rate commensurate with the risks involved.

      The uncertainties related to the outcome of the Corporation's Chapter 11
      proceedings and the resulting effect upon the ultimate value of the
      Corporation's financial assets and liabilities add significantly to the
      uncertain nature of any estimate of fair value.  The estimates of fair
      value required under SFAS No. 107 require the application of broad
      assumptions and estimates.  Accordingly, any actual exchange of such
      financial instruments could occur at values significantly different from
      the amounts disclosed.

      The following methods and assumptions were used to estimate the fair
      value of each class of financial instruments for which it is practicable
      to estimate that value:

      As cash and temporary cash investments, current receivables, current
      payables, and certain other short-term financial instruments are all
      short-term in nature, their carrying amount approximates fair value.  The
      estimated fair values of the Corporation's other financial instruments
      are reflected in the accompanying table.

      Long-term investments
      Long-term investments include escrowed proceeds from the sale of the
      Canadian subsidiary (see Note 6B), which consist of hedged Canadian
      Treasury bills ($25.4 million and $25.1 million for 1993 and 1992,
      respectively).  The Canadian Treasury bills are hedged with short-term
      foreign currency contracts, so that the combined carrying amount of the
      asset and related hedging instrument approximates fair value.  Long-term
      investments also include an income tax refund receivable with associated
      interest at IRS rates ($31.2 million for 1993) whose carrying amount
      approximates fair value.  Also included are loans receivable ($12.8
      million and $15.6 million for 1993 and 1992, respectively) whose
      estimated fair values are based on the present value of estimated future
      cash flows using an estimated rate for similar loans extended currently.
      It is not practicable to estimate the fair value of long-term receivables
      ($144.4 million and $154.2 million for 1993 and 1992, respectively) for
      the expected recovery by Columbia Transmission of certain gas purchase
      liabilities for which the timing and amount of payments to be received
      will be dependent on the outcome of the Chapter 11 proceedings.  As
      discussed in Note 2, the uncertainties related to these proceedings could
      significantly influence the fair value of this financial instrument.  The
      financial instruments included in long-term investments are primarily
      reflected in Investments and Other Assets in the Consolidated Balance
      Sheets.

      Liabilities subject to Chapter 11 proceedings
      The estimated fair value of the Corporation's debentures and medium-term
      notes is based on quoted market prices for those issues that are traded
      on an exchange, and estimates provided by brokers for other issues.
      However, quoted market prices and broker estimates inherently include
      judgments concerning the outcome of the Corporation's and Columbia
      Transmission's Chapter 11 proceedings.

      Note 2 discusses the uncertainties related to these proceedings which
      could significantly influence the fair value of these financial
      instruments.  It was not practicable to estimate the fair value of the
      remaining long-term debt, which includes the Subordinated Guarantee of
      the LESOP debt ($87.0 million) and miscellaneous debt of Columbia
      Transmission ($1.4 million for 1993 and 1992), because no reliable
      measurement methodology exists.  Prior to filing its petition for
      protection under Chapter 11 of the Bankruptcy Code, the Corporation
      regularly issued commercial paper, bank notes and other short-term debt
      instruments.  The carrying amount of such securities ($892.6 million) is
      included in Liabilities Subject to Chapter 11 Proceedings.  Payment of
      these obligations and any related interest is subject to approval by the
      Bankruptcy Court.  Although investors from time to time may buy and sell
      these debt obligations, the terms of any such transactions are private
      and not





                                       84
<PAGE>   85
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

      disclosed to the Corporation.  Because there can be no assurance as to
      the ultimate timing and amount of principal and interest repayments of
      these obligations, it is not practicable to determine their fair values.

      The carrying amount of other Liabilities Subject to Chapter 11
      Proceedings ($1,556.0 million and $1,595.4 million for 1993 and 1992,
      respectively) primarily represents accounts payable, accrued liabilities
      and other liabilities.  As discussed in Note 2, these liabilities are
      subject to adjustment at the direction of the Bankruptcy Court.  In
      addition, the timing of the ultimate payment of these liabilities, as
      well as interest, if any, is also subject to determination by the
      Bankruptcy Court.  Accordingly, it is not practicable to determine the
      fair value of these liabilities.

12.   OTHER COMMITMENTS AND CONTINGENCIES

  A.  CAPITAL EXPENDITURES.  Capital expenditures for 1994 are currently
      estimated at $468 million.  Of this amount, $91 million is for oil and
      gas operations, $201 million for transmission operations, $152 million
      for distribution operations and $24 million for other energy operations.

  B.  PRODUCER CONTRACT MATTERS.  Columbia Transmission has rejected more than
      4,800 natural gas purchase contracts which collectively made the
      company's gas sales rate noncompetitive.  Under Order 636, Columbia
      Transmission will have a minimal merchant function, i.e., less than one
      percent of total throughput.  Customers' requirements will be met with
      gas purchased under remaining and new contracts including 30- day spot
      contracts as may be required.  Rejection of additional contracts could
      result in liabilities that could require future charges against earnings.

  C.  PARTNERSHIP PROJECTS.  Columbia Gulf is a general partner in the
      Trailblazer, Overthrust and Ozark partnerships.  Since these partnerships
      are nonrecourse, project-financed pipelines, firm shipper contracts were
      assigned to banks (or in the case of Ozark to the Indenture Trustee) as
      collateral for loans.  Columbia Transmission and other shippers are
      attempting to negotiate exit fees under Order 636 with the partnerships.
      As a result of these negotiations and the current depressed demand for
      the capacity on several of these pipelines, the realizability of these
      investments is uncertain.  Accordingly, a reserve of $5.4 million was
      established in 1993.  At December 31, 1993, Columbia Gulf's investment in
      the partnerships amounted to $35.4 million, net of the valuation reserve
      and before related deferred taxes.

  D.  OTHER LEGAL PROCEEDINGS.  The Corporation and its subsidiaries have been
      named as defendants in various legal





                                       85
<PAGE>   86
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

      proceedings.   In the opinion of management, the ultimate disposition of
      these currently asserted claims will not have a material adverse impact
      on the Corporation's consolidated financial position or results of
      operations.

  E.  ASSETS UNDER LIEN.  The loans under the debtor-in-possession financing
      arrangement for the Corporation are given superpriority claim status
      pursuant to Section 364(c) (1) of the Bankruptcy Code.  Loans to the
      Corporation are secured by either a first or second priority perfected
      lien on, and security interest in, all property of the Corporation
      including intercompany loans, other than the voting securities of the
      Corporation's distribution subsidiaries and Columbia LNG.  Columbia
      Transmission's letter of credit facility is secured by either a first or
      second priority perfected lien on, and security interest in, all property
      of Columbia Transmission.

      Substantially all of Columbia Transmission's properties have been pledged
      to the Corporation as security for debt owed by Columbia Transmission to
      the Corporation.

  F.  COVE POINT LNG TERMINAL.  In 1991, the Corporation entered into a
      conditional agreement for the sale of its remaining interest in Columbia
      LNG to Shell LNG Company (Shell LNG), a subsidiary of Shell Oil Company.
      On July 16, 1992, the Corporation was notified by Shell LNG that it would
      not proceed with the interim purchase of 40.8 percent of the stock of
      Columbia LNG.  Shell LNG's notification terminated the agreements between
      the Corporation and Shell LNG for the purchase of the remaining Columbia
      LNG stock.  Shell LNG currently owns 9.2 percent of Columbia LNG's
      outstanding stock.

      As previously reported, Columbia LNG has developed a new business plan to
      reactivate the Cove Point facility.  This plan anticipated a new peaking
      and storage service by the end of 1994, as well as a terminalling service
      for liquefied natural gas (LNG) received by tanker.  An application with
      the FERC to charge customers based upon individually negotiated market
      rates was filed in February 1993.  In accordance with the business plan
      and in anticipation of the FERC filing, management concluded, in 1992,
      that it was no longer appropriate for Columbia LNG to continue
      application of SFAS No. 71 and regulatory assets were removed from
      Columbia LNG's balance sheet resulting in an extraordinary charge of
      $60.1 million pre-tax ($39.7 million after-tax) recorded in the third
      quarter of 1992.

      An open season, allowing potential customers to bid on the capacity of
      all of the offered services, was held March 31, 1993 through April 14,
      1993.  Based on the results of the bids, which were not sufficient to
      proceed with the project as it was originally proposed, Columbia LNG
      restructured the offered services to more adequately address the service
      needs of the potential customers.  A second open season, offering
      additional services, was held May 24, 1993 through June 2, 1993.  This
      open season resulted in sufficient bids to proceed with the peaking and
      transportation services.  The one bid received during the second open
      season for baseload terminalling service was subsequently withdrawn.  As
      a result, Columbia LNG does not currently anticipate a baseload
      terminalling service in the near future.  As a consequence, Columbia LNG
      recorded a writedown in the carrying value of its investment in the Cove
      Point facility in the second quarter 1993 that reduced the Corporation's
      income $37.9 million after-tax.  This amount included estimated
      dismantling costs for the offshore facilities of approximately $12
      million after-tax.  However, until such time as the offshore facilities
      are transferred to the new partnership, as discussed below, Columbia LNG
      plans to maintain the facilities for possible future imports and, at the
      present time, has no plans to abandon or dismantle them.  Besides the
      writedown discussed above and the extraordinary charge discussed in the
      preceding paragraph, Columbia LNG has incurred operating losses during
      the prior three years which are not significant to the consolidated
      financial results of the Corporation.

      On October 28, 1993, as amended on January 27, 1994, PEPCO Enterprises,
      Inc. (PEPCO), which is a wholly-owned subsidiary of Potomac Electric
      Power Company, entered into an agreement to form a limited partnership.

      The February 1993 filing with the FERC was withdrawn by Columbia LNG and
      the Partnership, Cove Point LNG Limited Partnership (Cove Point LNG) that
      will pursue the business plan discussed above, filed an

      application with the FERC on November 3, 1993, seeking authorization to
      acquire all of the existing plant and pipeline facilities owned by
      Columbia LNG and for authorization to recommission the plant and
      construct new facilities in order to provide peaking services beginning
      in 1995.  On the same day, Columbia LNG filed with the FERC for
      authorization to abandon its facilities by transfer to Cove Point LNG and
      to withdraw its February 26, 1993 filing.  In addition to the FERC, this
      transaction will require other governmental approvals. Bankruptcy Court
      approval was received in January 1994.

      After the receipt of necessary regulatory approvals, the PEPCO affiliates
      will contribute up to $25 million in equity and loans for their half
      interest in the partnership.  At the same time, Columbia LNG will
      transfer title to its existing plant and pipeline facilities to the
      partnership and assign to the partnership the precedent agreements for
      the services to be offered.  Any cash requirements of the partnership
      prior to the in-service date of the project which are in excess of $25
      million will be provided by Columbia LNG up to a maximum of $7 million.
      The cost of recommissioning the Cove Point facility and installing the
      necessary liquefaction equipment is estimated to be approximately $27
      million.  Columbia LNG or an affiliate will operate the plant and
      pipeline facilities for the partnership.

      A number of intervenors filed with the FERC in regard to Columbia LNG's
      plan for the Cove Point facility.  While generally supportive of the plan
      to reopen the facility, some of the intervenors questioned the use of the
      individually negotiated market rates and requested the pass-through of
      certain benefits from prior collections from Columbia Transmission.

      The realization of the Corporation's remaining investment in Columbia LNG
      of $10.1 million will be dependent upon successful implementation of the
      partnership and related business plan.

  G.  OPERATING LEASES.  Payments made in connection with operating leases are
      charged to operation and maintenance expense as incurred.  Such amounts
      were $55.5 million in 1993, $57.9 million in 1992 and $57.9 million in
      1991.  Future minimum rental payments required under operating leases
      that have initial or remaining noncancelable lease terms in excess of one
      year are:

  H.  ENVIRONMENTAL MATTERS.  The Corporation's subsidiaries are subject to
      extensive federal, state and local laws and regulations relating to
      environmental matters.  These laws and regulations, which are constantly
      changing, require expenditures for corrective action at various operating
      facilities, waste disposal sites and former gas manufacturing sites for
      conditions resulting from past practices that subsequently were
      determined to be environmentally unsound.

      Certain subsidiaries have received notice from the United States
      Environmental Protection Agency (EPA) that





                                       87
<PAGE>   88
ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

      they are among several parties responsible under federal law for placing
      wastes at Superfund sites and may be required to share in the cost of
      remediation for these sites.  However, considering known facts, existing
      laws and possible insurance and rate recoveries, management does not
      believe the identified Superfund matters will have a material adverse
      effect on future annual income or on the Corporation's financial
      position.

      The transmission subsidiaries are continuing their comprehensive review
      of compliance with existing environmental standards, including review of
      past operational activities and identification of potential site
      problems, through site reviews and formulation of remediation programs
      where necessary.  While the Corporation's transmission subsidiaries have
      made progress in these ongoing self-assessment programs, because of the
      thousands of miles of pipeline which they operate, the exceptionally
      large number of sites at which they conduct or have conducted operations,
      and the long period over which operations have been conducted, completion
      of site screenings, characterizations and site-specific remediations will
      cover a time frame of approximately 10 to 12 years.

      A study for Columbia Transmission to quantify the scope of remediation
      activities which will be undertaken in future years to address the issues
      identified was recently concluded.  The study, site investigations and
      characterization efforts performed throughout 1993 resulted in total
      accruals for the year of approximately $60 million for Columbia
      Transmission.  These and other minor adjustments bring Columbia
      Transmission's recorded net liability to approximately $143.6 million at
      December 31, 1993.  This represents the lower end of the range of
      reasonable outcomes with the upper end estimated to total approximately
      $280 million based on information currently available.

      As characterization and site-specific activities by Columbia Transmission
      determine the nature and extent of contamination, if any, at its
      operating facilities and as remediation plans are developed, additional
      charges to earnings could occur.  To the extent such plans require
      approval of federal and/or state authorities, estimates are subject to
      revision.  Based on the limited data now available and various
      assumptions as to characterization, management believes that annual
      future expenditures for Columbia Transmission's site investigations,
      characterization and remediation activities could be up to $20 million
      per year over an approximate 10 to 12 year time frame.  Earnings will
      continue to be charged appropriately in advance of required expenditures.

      As a result of site characterization studies at various locations, during
      1993, Columbia Gulf recorded an additional accrual of $6.7 million for
      environmental remediation.  This accrual is for polychlorinated biphenyl
      (PCB) and petroleum hydrocarbon cleanup at certain compressor station
      sites and screenings for possible exposure at other locations.  Columbia
      Gulf anticipates completion of cleanup during 1994.  At that time, costs
      of remediation, if any, will be quantified and an additional accrual may
      become necessary.

      In 1992, Columbia Transmission received a subpoena and information
      request (Request) from the EPA Region III regarding three major
      environmental statutes:  The Toxic Substances Control Act (TSCA), the
      Resource Conservation and Recovery Act (RCRA) and the Comprehensive
      Environmental Response Compensation and Liability Act (CERCLA).  The
      Request relates to Columbia Transmission's past and current environmental
      practices.  Since receipt of the Request, Columbia Transmission has
      provided the EPA with various materials pursuant to the Request.
      Columbia Transmission has continued to meet with the EPA to attempt to
      resolve the subpoena issues and continues to work cooperatively with
      environmental officials in the various states in which it operates.  All
      environmental agencies have been declared exempt from the Bar Date
      established by the Bankruptcy Court for claims by creditors.

      Columbia Transmission on January 28, 1994, received from EPA Region V an
      Information Request pursuant to the RCRA.  The agency requested Columbia
      Transmission to submit information and knowledge relating to its
      generation and management of natural gas pipeline condensate, used engine
      oil and similar liquids in the state of Ohio. Columbia Transmission is in
      the process of analyzing the information requested and will be discussing
      this Information Request with EPA Region V.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

      At least one distribution subsidiary and some of the predecessor
      companies of the distribution subsidiaries were, or may have been,
      involved with the ownership and/or the operation of manufactured gas
      plants.  At the present time management is aware of twelve such sites.
      The distribution subsidiaries are conducting investigations at five sites
      that date back to the mid-1800s.  These plants heated coal tar in a
      low-oxygen atmosphere to manufacture low-cost gas for areas where natural
      gas was not generally available.  The process created residues such as
      coal tar which were typically stored on site prior to being sold for
      commercial use.  However, when the plants stopped operation the remaining
      residue material was in some cases simply buried on the plant sites.  As
      time passed, other uses were made of the plant sites and in some cases
      their identity as a manufactured gas plant was lost.  To the extent site
      investigations have been completed, remediation plans developed, and any
      responsibility for remedial action established, the appropriate liability
      has been recorded.  The environmental assessment and evaluation process
      will continue over the next three to five years.  Environmental
      investigations indicate that remedial action may be required.
      Investigations will be conducted at a number of the other sites in the
      near future.  The following discusses the status of certain sites:

      In 1985, CPA was cited by the Pennsylvania Department of Environmental
      Resources for coal tar residues on the bottom of a creek bed in York,
      Pennsylvania.  The area was adjacent to the site of a manufactured gas
      plant operated from 1885 to the early 1950s by a predecessor company, the
      York County Gas Company, which was purchased in 1968.  The site has been
      under investigation by CPA's consultants to determine the extent of any
      underground contamination and to propose various remedial measures that
      can be used to eliminate the release to the creek or remediate the
      premises.  The current costs of the investigation are being recovered in
      rates.  Site remediation costs have been estimated at $4.2 million, which
      has been recorded as a liability and a corresponding regulatory asset.
      CPA expects to continue to recover these costs in rates based upon orders
      received in previous rate cases.  However, the ability to recover these
      costs is subject to (1) the results of each future rate case during the
      expenditure period or (2) the outcome of a settlement proposal to treat
      these expenditures as a cost of removal by charging them to the reserve
      for depreciation and recover them over a five-year period.  Remediation
      work is expected to start in 1994.

      Penn Fuel Gas, Inc. (Penn Fuel) advised CPA that a site in Bellefonte,
      Pennsylvania, sold to Penn Fuel by Central Pennsylvania Gas Company in
      1960 was the location of a manufactured gas plant until the mid-1950s.
      The plant's equipment was disassembled at the time Penn Fuel acquired the
      property.  The old processing building is still used as a warehouse by
      Penn Fuel.  In 1966, CPA acquired substantially all of Central
      Pennsylvania Gas Company's assets and liabilities.

      CPA has agreed to share with Penn Fuel, the costs of investigating the
      site for environmental contamination and up to $300,000 of the
      investigation costs.  A regulatory asset and offsetting liability was
      recorded by CPA in March 1993.  There is no agreement, nor is there any
      admission by either CPA or Penn Fuel, regarding liability, if any, for
      abatement and/or remediation of the site.  It is expected that the
      positions and potential responsibility of each party will become clearer
      as the investigation proceeds.

      In January 1993, the owners of the Patio Plaza Apartments, BMI Apartment
      Associates (a partnership), contacted COS about possible soil
      contamination of a site in Portsmouth, Virginia, on which the Portsmouth
      Gas Company operated a manufactured gas plant from 1854 to 1951.  The
      Portsmouth Gas Company sold this site to the Portsmouth Redevelopment and
      Housing Authority in 1960.  The Portsmouth Gas Company was acquired by
      Commonwealth Natural Resources, Inc. and subsequently merged into COS in
      1981.  The Redevelopment Authority subsequently razed the plant and sold
      the vacant land.  Apartments and houses were built on the property and
      the current owners of some of the apartments reported possible soil
      contamination to the Virginia Water Quality Control Board.  COS notified
      the EPA regarding the engineering reports provided to it by the owners.

      On March 25, 1993, COS and the Portsmouth Redevelopment and Housing
      Authority jointly filed suit in U.S. District Court, Eastern District of
      Virginia at Norfolk, Virginia, against the current and former owners of
      the apartments.  The suit sought a declaration that those other parties
      are liable for the site and requested access to the property for testing
      which had been denied by the current owners.  On June 14, 1993, the Court
      ordered





                                       89

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (Continued)

      that COS be permitted access to perform necessary testing of soil and air
      that resulted in a determination that there was no imminent danger to the
      residents.  Subsequently, the Court granted a stay of all legal
      proceedings until May 16, 1994 to permit COS to conduct further site
      testing to determine the extent of any contamination and to recommend
      corrective measures.  Most of that testing was completed in November and
      December 1993, and the results are anticipated in early 1994.  On
      February 14, 1994, the judge appointed a magistrate to oversee settlement
      of the suit.

      COS incurred legal and engineering consultant expenses that reached
      approximately $400,000 in 1993. Additional costs are currently
      anticipated to reach $400,000 in 1994 and accordingly a regulatory asset
      has been established for $800,000 and the appropriate liability recorded.
      Other work at this site is anticipated but it is not possible at this
      time to estimate the costs. Permission was granted by the VSCC to defer
      the costs of this project as a regulatory asset, subject to recovery in
      the next rate case.

      In February 1993, COS reported to the Virginia Department of
      Environmental Quality (VaDEQ) a potential soil contamination below a
      retaining wall at the Petersburg, Virginia Service Center . The VaDEQ has
      ordered COS to prepare a preliminary site assessment related to the
      report. In early June 1993, COS contractors performed testing and
      prepared the preliminary site assessment which was submitted to VaDEQ in
      July 1993.  Additional testing on another area of leakage was conducted
      in September 1993 with results reported to the VaDEQ in late October
      1993.  COS is currently completing the removal of contaminated material
      from an old underground tank on the property which was contributing to
      the leakage problem. Additional corrective work may be performed in 1994
      as a result of further testing that will be conducted.

      COS has incurred legal and engineering consultant expenses that reached
      approximately $170,000 by the end of 1993.  At this time, it is not
      possible to estimate the costs of corrective action or of further work
      the VaDEQ might require.  However, additional consultant costs are
      estimated to be $280,000 in 1994.  Accordingly, a regulatory asset of
      $450,000 has been established and the liability recorded.  Permission was
      granted by the VSCC to defer the costs of this project as a regulatory
      asset subject to recovery in the next rate case.

      A former manufactured gas plant site in Lynchburg, Virginia was included
      with the assets of the Lynchburg Gas Company when it was merged into COS
      in 1989.  A liability of $600,000 has been recorded for the removal of
      certain remaining structures from the manufactured gas plant and clean up
      of debris at the site.  The VSCC has granted COS permission to defer the
      costs associated with this work and any other remediation related to the
      site for review and potential recovery in rates at a later time.

      A former manufactured gas plant site in Hagerstown, Maryland was included
      with other assets of the Hagerstown Gas Company acquired by CMD in 1969.
      This plant operated between 1891 and 1949.  The site, at the location of
      the CMD service center in Hagerstown was reported to the EPA by the state
      and has been assigned medium priority status by the EPA for future
      investigation.  No investigations have been conducted by the state of
      Maryland or the EPA at this site and, therefore, it is not possible at
      this time to estimate the cost of remediation activities, if any.

      To the extent the above-mentioned site investigations have been
      completed, remediation plans developed, and any Distribution
      responsibility for remedial action established, the appropriate liability
      has been recorded.  As additional investigations are completed and
      remediation costs become probable, the appropriate liability will be
      recorded.  As of December 31, 1993, the distribution subsidiaries
      recorded net liabilities of $5.9 million.  Management anticipates
      recovery of remediation costs through normal rate proceedings.

      The eventual total cost of full future environmental compliance for the
      Columbia Gas System is difficult to estimate due to, among other things:
      (1) the possibility of as yet unknown contamination, (2) the possible
      effect of future legislation and new environmental agency rules, (3) the
      possibility of future litigation, (4) the possibility of future
      designations as a potential responsible party by the EPA and the
      difficulty of determining liability, if any, in proportion to other
      responsible parties, (5) possible insurance and rate recoveries, and (6)
      the effect of possible technological changes relating to future
      remediation.  However, reserves have been





                                       90

      established based on information currently available which resulted in a
      total recorded net liability of $156.1 million for the Columbia Gas
      System at December 31, 1993, which includes the low end of a range for
      certain expenditures for the transmission segment previously discussed.
      As new issues are identified, appropriate additional liabilities may have
      to be recorded.

      It is management's continued intent to address environmental issues in
      cooperation with regulatory authorities in such a manner as to achieve
      mutually acceptable compliance plans.  However, there can be no assurance
      that fines and penalties will not be incurred.

      Management expects most environmental assessment and remediation costs to
      be recoverable through rates.  Although significant charges to earnings
      could be required  prior to rate recovery, management does not believe
      that environmental expenditures will have a material adverse effect on
      the Corporation's financial position, based on known facts, existing laws
      and regulations and the period over which expenditures are required.

18.  OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED)

     INTRODUCTION.  Reserve information contained in the following tables for
     the U.S. properties is management's estimate, which was reviewed by the
     independent consulting firm of Ryder Scott Company Petroleum Engineers.
     Reserves are reported as net working interest.  Gross revenues are
     reported after deduction of royalty interest payments.

     The Corporation sold its Canadian subsidiary to Anderson Exploration Ltd.
     of Calgary effective December 31, 1991. In 1991 the oil and gas operations
     of the Canadian subsidiary resulted in a $24.4 million loss.  Accordingly,
     the reserve and other information for the Canadian properties are not
     included in the tables for 1991, 1992 and 1993.

</TABLE>

      Future cash inflows are computed by applying year-end prices to estimated
      future production of proved oil and gas reserves.  Future expenditures
      (based on year-end costs) represent those costs to be incurred in
      developing and producing the reserves.  Discounted future net cash flows
      are derived by applying a 10% discount rate, as required by the Financial
      Accounting Standards Board, to the future net cash flows.  This data is
      not intended to reflect the actual economic value of the Corporation's
      oil and gas producing properties or the true present value of estimated
      future cash flows since many arbitrary assumptions are used.  The data
      does provide a means of comparison among companies through the use of
      standardized measurement techniques.

      to the economic feasibility of producing certain wells.  The standardized
      measure of the Corporation's oil and gas properties can be influenced by
      affiliated and unaffiliated pipeline transportation rate design (which
      continues to be evaluated by the FERC).

(a)   Prior to June 19, 1991, certain working capital requirements of the
      Corporation and its subsidiaries were met through the sale of commercial
      paper, through notes sold directly to commercial banks and/or through
      borrowings under bank lines of credit.  The commercial paper was sold
      through dealers with maturities ranging from one day to nine months.  The
      Corporation maintained a $500 million revolving short-term committed line
      of credit, for which participating banks were paid fees of 1/8% per annum
      on the total facility and 1/16% per annum on the unused portion of the
      facility.  In addition, a $750 million revolving

                           SHORT-TERM BORROWINGS (A)                Schedule IX

      subordinated committed line of credit was maintained, for which
      participating banks were paid 3/8% per annum on the unused portion of the
      facility.  Loans under the lines of credit bore interest according to
      rate options based on prime, bank certificates of deposit or the London
      InterBank Offered Rate.  Since its Chapter 11 filing, the Corporation has
      had $266.5 million of commercial paper and $621 million of bank loans in
      default under these facilities.

      For periods subsequent to the Chapter 11 filings, Debtor-In-Possession
      (DIP) Financing facilities were established by the Corporation and
      Columbia Transmission.  The Corporation has available up to $100 million,
      reduced from $200 million on June 18, 1993, under its DIP Financing
      facility.  Borrowings are at the agent's per annum alternate reference
      rate plus 1% or the Eurodollar Rate plus 2-1/4% (for either 1, 2 or 3
      months).  Also, the Corporation is subject to a commitment fee of
      one-half of 1% per annum on the average daily unused amount of the
      facility.  Additionally, Columbia Transmission's separate DIP facility
      initially of up to $80 million was reduced to $25 million, on November
      29, 1991, which is only available for the issuances of Letters of Credit.
      Borrowings were at the agent's per annum alternate reference rate plus
      1-1/2% or the Eurodollar Rate plus 2-3/4% (for either 1, 2 or 3 months).
      Columbia Transmission is also subject to a commitment fee of one-half of
      1% per annum on the average daily unused amount of the facility.

      For additional information regarding these DIP facilities, reference is
      made to pages 51 and 52 of Management's Discussion and Analysis in Item 7
      and Note 10 in Item 8 on page 83.  Reference is also made to the DIP
      Financing Exhibits 10-BR, 10-CB, 10-CC, 10-CD, 10-CF, 10- CG, 10-CH,
      10-CK and 10-CL included or incorporated by reference, in this filing.

(b)   Based on actual interest expense divided by the average daily borrowings
      outstanding during the period.

(c)   The Corporation did not have any amounts outstanding under its DIP
      facility during 1993.  However, the Corporation's facility was used
      during the periods January 1, 1992 through December 31, 1992 and August
      20, 1991 through December 31, 1991.  Columbia Transmission did not have
      any amounts outstanding under its DIP facility during 1993 and 1992.
      However, the facility was used during the period of August 6, 1991
      through August 21, 1991.  Both the Corporation's and Columbia
      Transmission's DIP facilities include the availability of letters of
      credit of up to $50 million and $25 million, respectively.  As of
      December 31, 1993, $12.8 million and $1.8 million of letters of credit
      were outstanding under the Corporation's and Columbia Transmission's DIP
      facilities, respectively.

(d)   The period used in calculating the amounts for short-term financing was
      from January 1, 1991 through June 18, 1991.  This period represents the
      time during which the Corporation was not in default of its loan
      agreements.

Undertaking made in Connection with 1933 Act Compliance on Form S-8
For purposes of complying with the amendments to the rules governing Form S-8
under the Securities Act of 1933, the Corporation undertakes the following,
which is incorporated by reference into the registration statements on Form
S-8, Nos. 33-10004 (filed November 26, 1986) and 33- 42776 (filed September 13,
1991):

Insofar as indemnification for liabilities arising under the Securities Act of
1933 (Act) may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the questions whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                                   WITNESSETH

                  WHEREAS, TCO owns and operates three underground natural gas

            located in Greene and Washington Counties, Pennsylvania, as well as
            Marshall County, West Virginia; and

                  WHEREAS, Companies currently own and/or operate coal mining
            operations in Greene and Washington Counties, Pennsylvania, as well
            as Marshall County, West Virginia; and,

                  WHEREAS, the Storage Complex and the mining operations
            underlie some of the same surface land which, at present, requires
            TCO and Companies each to operate their respective facilities with

                  WHEREAS, TCO and Companies desire to enter this Agreement

                  NOW, THEREFORE, for and in consideration of the premises,
            which are incorporated and the mutual promises, covenants and
            agreements hereinafter set forth, TCO and Companies, with intent to
            be legally bound, agree as follows:

            temporary deactivation of the Majorsville Shallow Storage Field
            when required under Section  5.01(a)(v) hereof. The temporary

                  which acceptance shall not be unreasonably withheld.

                        (b)   Regulatory Contingency.  TCO shall have received
                  all regulatory approvals required to perform its duties and
                  obligations under this Agreement, including Federal Energy
                  Regulatory Commission ("FERC") approval of TCO's temporary
                  deactivation of the Storage Complex in accordance with the
                  provisions of Article 5 hereof during the term of this
                  Agreement, such approvals to be final and no longer subject
                  to rehearing or appeal and in form and substance acceptable
                  both to TCO and to Companies, which acceptance shall not
                  unreasonably be withheld.  It is currently anticipated by the
                  parties that TCO shall file for and receive from FERC a
                  Section 7(c) order pursuant to the Natural Gas Act [15 U.S.C.
                  717(f)] which shall amend or replace the current certificate
                  issued by FERC to TCO in FERC Docket No. CP88-866.

                  3.02  Cooperation by Companies.  Companies shall cooperate
            with TCO in obtaining the approval(s) to be sought by TCO in order
            to implement this Agreement, including the furnishing of data (not
            competitively sensitive or otherwise proprietary in nature as
            determined in Companies' sole discretion) which may be required by
            TCO to respond to any data request or regulatory requirement in the
            proceedings to obtain the approvals contemplated by Section 3.01.

                  3.03  Copies of Filings.  After the date of execution of this
            Agreement, TCO shall promptly make Companies aware of, and provide
            to them, copies of all filings or other communications relating to
            any approvals concerning the contingencies set out in this Article
            3 with federal, state or local government agencies or the
            Bankruptcy Court, or any subsequent filings or other communications
            relating to such approvals.  Any objections by Companies shall be
            considered by TCO.

                              ARTICLE 4:  PAYMENTS

                  4.01  Five (5) Installment Payments.  In consideration for
            the temporary deactivation of the Storage Complex and as
            reimbursement for leasehold maintenance and other costs to be
            incurred by TCO, Companies will pay to TCO, subject to the
            conditions set forth in Section Section  3.01 and 4.03 hereof, a
            total of twenty million dollars ($20,000,000) in five (5)
            installments under the following schedule:

<TABLE>
<CAPTION>
                        Amount            Due Date
                        ------            --------
                  <S>   <C>         <C>
                  (1)   $4,000,000  the Initial Payment Date;

                  (2)   $5,000,000  twelve (12) months after the Initial Payment Date;

                  (3)   $5,000,000  twenty-four (24) months after the Initial Payment
                                    Date;

                  (4)   $4,000,000  thirty-six (36) months after the Initial Payment Date;


                  (5)   $2,000,000  forty-eight (48) months after the Initial Payment Date
</TABLE>


                  4.02  Interest on Late Payments.  Any amount due under
            Section  4.01 but not paid by the applicable due date shall accrue
            interest at the higher rate of (i) the rate then provided for
            interest on amounts due but not paid under TCO's FERC Gas Tariff or
            (ii) the prime rate applicable for the calendar quarter under the
            then current FERC refund regulation [now codified as 18 C.F.R.
            Section  154.67(c)(2)(iii)(A)].

                  4.03  Payment Conditions.  Installment payments which become
            due pursuant to the provisions of Section  4.01 hereof shall be
            made by Companies subject to both the conditions set forth in
            Section  3.01 hereof and the following conditions:

                        (a)   Payments Made Prior to Plan Consummation.
            Installment payments which become due and are paid by Companies
            during the period that TCO's reorganization proceeding, as
            specified in Section  3.01(a) hereof, remains pending prior to Plan
            Consummation as that term is defined in the Plan shall, by
            agreement of the parties hereto and incorporated in the Order
            approving this Agreement, be treated as administrative claims if
            mining operations are interrupted or curtailed as specified in
            Section  4.03(b) below; however, absent any such interruption or
            curtailment, the right of Companies to file an administrative claim
            shall automatically terminate upon the date of Plan Consummation.

                        (b)   Interruption or Curtailment of Mining Operations.
            In the event that Companies' mining operations within the outer
            boundaries of the Storage Complex are interrupted or curtailed as a
            result of (i) the operation of any order issued by the FERC or any
            successor agency, or any other governmental entity or court having
            jurisdiction in the matter, relating to the temporary deactivation
            of the Storage Complex by TCO in accordance with the provisions of
            Article 5 hereof, or (ii) an action or omission of TCO or any of
            its affiliates, or of any employee, agent or contractor of TCO, in
            the discharge of, or failure to discharge, TCO's obligations
            relating to the temporary deactivation of the Storage Complex under
            this Agreement, then, in such event:

                              (i)   Before Final Installment Payment Made.
                  Companies may withhold any installment payments which become
                  due after such interruption or curtailment until the reason
                  for such interruption or curtailment is cured by TCO.  Such
                  period of suspension shall not count as calendar time to be
                  measured beyond the Initial Payment Date pursuant





                                       3
<PAGE>   8





                  to the installment payment schedule of Section  4.01, so that
                  said schedule shall be extended for a period of equal
                  duration to said suspension.

                              (ii)  After Final Installment Payment Made.  The
                  Companies may transfer to TCO the duty and sole
                  responsibility for the cost of and the plugging of or
                  replugging of wells as specified in Section 5.01(b)(ii) at
                  the rate of two (2) well(s) for each full calendar day that
                  the mining operations of Companies are interrupted or
                  curtailed.  The particular wells subject to such transfer
                  shall be determined at the sole discretion of Companies.  As
                  to each and every occurrence which happens after all
                  installment payments are made and before twenty (20) years
                  after the Effective Date, two (2) well(s) shall be
                  transferred for the first full day of interruption or
                  curtailment and continue at that rate of two (2) well(s) per
                  day until the first full day following the day that the
                  impediment to full mining production has been removed.  Any
                  amounts paid by TCO pursuant to Section  4.03(c) below shall
                  not be considered as an offset against the costs incurred by
                  TCO for plugging or replugging wells under this Section
                  4.03(b)(ii).

                        (c)   TCO Refund of Payments.  If Companies' mining
            operations are interrupted or curtailed, for any reason stated in
            Section  4.03(b) above, and if such interruption or curtailment
            continues for a period of one (1) year, TCO shall, subject to
            Section  4.03(d) hereof, refund to Companies all installment
            payments previously made by Companies pursuant to Section  4.01
            along with interest calculated at the rate provided in Section
            4.02 hereof from the date of the beginning of such interruption or
            curtailment until the date of refund by TCO.  This remedy for
            interruption or curtailment of mining operations shall be in
            addition to the remedies provided in Section  4.03(a) and (b)
            above.  Any costs incurred by TCO for plugging or replugging wells
            pursuant to Section  4.03(b)(ii) above shall not be considered as
            an offset against amounts owed by TCO under this Section  4.03(c).

                        (d)  TCO Adjustment to Refunds.  Beginning sixty (60)
            months after the Initial Payment Date, TCO shall be able to retain,
            from the installment payment amounts which must be refunded to
            Companies pursuant to Section 4.03(c) hereof, the sum of one
            million dollars ($1,000,000) for each and every additional twelve
            (12) month period during which temporary deactivation of the
            Storage Complex continues to be effected in accordance with the
            provisions of Section  5.01 hereof.

                        (e)   Additional Remedies.  It is expressly agreed that
            the payments provided in Section  4.03(c) and any transfers of
            responsibility for plugging or replugging wells which may be
            effected pursuant to Section 4.03(b)(ii) may not cover all damages
            that Companies may suffer as a result of interruption or
            curtailment of mining operations for any reason stated in Section
            4.03(b) above, and Companies reserve their rights to any additional
            remedies available to them under this Agreement or at law or in
            equity, subject to credit for such Section  4.03(c) payments made
            and for the cost of plugging or replugging wells pursuant to
            Section  4.03(b)(ii).

                        (f)  Irreparable Harm.  TCO acknowledges that Companies
            will suffer irreparable harm, (which for purposes hereof shall mean
            damage for which a remedy at law may not be adequate), if their
            mining operations are interrupted or curtailed for any reason
            stated in Section  4.03(b) above, and, TCO, therefore, agrees that
            it shall use all reasonable efforts to:  (1) avoid any such
            interruption or curtailment, (2) correct any action or omission
            which may have caused such interruption or curtailment, and (3)
            assert and pursue diligently all remedies and defenses available to
            TCO to contest any order contemplated in Section  4.03(b) above.
            TCO further agrees that it shall not deny in court or otherwise
            that Companies will suffer such irreparable harm.

                        (g)   Non-applicability of Payment Conditions.  In the
            event that Companies' mining operations within the outer boundaries
            of the Storage Complex are interrupted or curtailed directly or
            indirectly as a result of:





                                       4
<PAGE>   9





            (i) an action or omission of Companies, or any of their affiliates,
            or any employee, agent or contractor of Companies, in the discharge
            of, or failure to discharge, Companies' obligations under Article 5
            of this Agreement; or (ii) as a result of the operation of any
            order issued by the Mine Safety and Health Administration, or any
            successor agency, which does not result in whole or in part from
            TCO's action or omission; then as to that particular interruption
            or curtailment of mining operations, the payment conditions set
            forth above in this Section  4.03 shall not apply.



                     ARTICLE 5:  OPERATIONS BY THE PARTIES

                  5.01  Accommodation of Mining Operations.  As to this
            Agreement, the rights of Companies to mine the coal shall be
            considered "dominant" while the rights of TCO to operate the
            Storage Complex shall be considered "servient".

                        (a)   In General.  After the date of the signing of
            this Agreement, TCO will not oppose and will cooperate with mining
            operations by Companies within the area of the Storage Complex as
            follows:

                              (i)  Cessation of Storage Injection.  The parties
                  recognize that mining activity has occurred and will continue
                  to progress in areas overlying reservoirs within the Storage
                  Complex.  To alleviate TCO's concern about the operation of
                  the Storage Complex while Companies are engaged in
                  underground mining within the boundaries of and overlying the
                  storage reservoirs, TCO will not, after the date of this
                  Agreement, further inject gas generally in the vicinity of
                  mining operations and specifically not in Heard (which
                  utilizes the 50 Foot Sand and 30 Foot Sand formations), nor
                  will TCO further inject gas in the Pennsylvania part of
                  Majorsville Deep (which utilizes the Big Injun formation);
                  and TCO shall not inject gas in the West Virginia part of
                  Majorsville Deep (which utilizes the Big Injun formation)
                  after October 31, 1993.  Before November 1, 1993, TCO shall
                  have the right to inject gas into the West Virginia part of
                  Majorsville Deep (Big Injun formation), so as to preserve
                  deliverability from the West Virginia storage wells in the
                  1993-94 winter season.

                              (ii)  Pressure Limitations.  TCO shall utilize
                  its compressor and pipeline facilities (existing on the
                  Effective Date) and active storage wells [including any new
                  storage wells drilled pursuant to Section  5.01(d)] so as to
                  reduce reservoir pressures in each of the reservoirs included
                  in the Storage Complex as low as reasonably possible in the
                  vicinity of mining.  In addition, unless Companies notify TCO
                  in writing of a change in their forecasted operations, TCO
                  shall use its best efforts to maintain its active storage
                  wells (for this purpose of this Section  5.01(a)(ii),
                  Injection-Withdrawal Wells and Special Wells) on
                  withdrawal-only status with minimal shut-ins limited to those
                  necessary on account of the physical limitations of the
                  Storage Complex facilities, and including, to the extent
                  reasonably possible, the reinjection of gas withdrawn
                  elsewhere in the Storage Complex into the Majorsville Shallow
                  reservoir, as well as maximizing the delivery of gas
                  withdrawn to TCO's low pressure markets, concentrating the
                  withdrawal by groups of wells which Companies and TCO agree
                  to prioritize as follows:

                              (A)   The Heard Storage Reservoir;
                              (B)   the portion of the Majorsville Deep Storage
                                    Reservoir located within Pennsylvania;
                              (C)   the portion of the Majorsville Deep Storage
                                    Reservoir located within West Virginia; and
                              (D)   the Majorsville Shallow Storage Reservoir,
                                    starting two (2) years after receipt of the
                                    Notice as provided for in Section
                                    5.01(a)(v).

                              (iii)  Projected Withdrawals and Resulting
                  Volumes in Storage.  In connection with its undertakings in
                  Section Section 5.01(a)(i), (a)(ii), and (a)(v), TCO has
                  delivered to Companies a graph showing its projected volumes
                  in storage resulting from its anticipated withdrawals
                  [including 1993 injections in the West Virginia portion of
                  Majorsville Deep, as provided in Section  5.01(a)(i), and
                  injections in Majorsville Shallow subject to the provisions
                  of Section  5.01(a)(v)] in the Storage Complex.  A copy of
                  the graph is attached hereto as Exhibit "B".  TCO shall use
                  its best efforts to meet or exceed its anticipated
                  withdrawals so as to attain the projected volumes in storage,
                  and shall not change its operational plan except (A) to
                  handle the unforeseeable consequences of "force majeure" as
                  defined in TCO's Gas Tariff, in which event TCO shall use its
                  best efforts to minimize the impact of the force majeure on
                  the projected net withdrawals as now scheduled or (B) to
                  utilize the storage potential of acreage which may be
                  released by Companies to TCO under Section  5.01(a)(iv).
                  Further, TCO acknowledges that payments made or to be made by
                  Companies pursuant to Section  4.01 hereof, are based on a
                  reliance by Companies that TCO shall use its best efforts to
                  meet or exceed its projected volumes in storage as shown on
                  the aforementioned Exhibit "B".

                              (iv)  Companies' Release of Acreage to Permit
                  Storage Reactivation.  At any time during the term of the
                  Agreement, Companies reserve the right to offer to release to
                  TCO for storage reactivation parts of the Storage Complex
                  which Companies decide in their sole discretion not to mine,
                  or not to mine in other coal seams above or below a  mine
                  abandoned or to be abandoned by a date certain.  Companies
                  will prepare a map showing the area(s) to be released, which
                  shall include all wells then remaining unplugged within the
                  perimeter line(s) of the area(s) offered for release.  TCO
                  shall have one (1) year to accept the offer of all of the
                  acreage included in the offer or to counteroffer to accept
                  part(s) of the acreage, or Companies' offer will
                  automatically terminate.  If TCO, in its sole discretion,
                  accepts in writing all of the acreage offered for release, or
                  if Companies, in their sole discretion, accept TCO's
                  counteroffer within six (6) months after tender, then, as of
                  the date of either TCO's or Companies' acceptance:  (A) the
                  released acreage and all wells therein shall be excluded from
                  this Agreement as fully as if same had never been included;
                  and (B) Companies shall promptly execute, acknowledge, and
                  deliver to TCO deeds or other recordable documents which
                  subordinate Companies' mining rights (then owned in fee
                  rather than leased) to TCO's storage rights, so that all
                  rights that Companies then own in fee to mine coal in the
                  released acreage shall thereafter be "servient" while the
                  rights to operate for underground gas storage shall
                  thereafter be "dominant"; and (C) as to the released acreage,
                  Companies shall assign to TCO the mining leases or relevant
                  portions thereof that are assignable without additional cost
                  to Companies, if any, which TCO selects at its sole
                  discretion to accept from Companies and upon acceptance, TCO
                  shall become liable for all duties and obligations of
                  Companies (Assignors) which accrue under said mining leases
                  after the date of such assignment.

                              (v)  TCO's Right to Use Majorsville Shallow for
                  Gas Storage.  TCO may continue to use Majorsville Shallow
                  reservoir for active storage operations until two (2) years
                  from the date on which it receives written Notice from
                  Companies of the approach of mining:  Provided, that such
                  Notice may not be given earlier than January 1, 1995.  From a
                  date two (2) years after receipt of the Notice, TCO shall not
                  further inject gas in Majorsville Shallow, and shall
                  otherwise proceed with deactivation so as to reduce reservoir
                  pressures to as low as reasonably possible in order that such
                  pressures comply with Section  5.01(a)(ii) above.  If, during
                  the term of this Agreement, Companies do not give the written
                  Notice provided for herein, then TCO shall retain the duty to
                  plug all wells remaining within the area designated as
                  Majorsville Shallow on Exhibit "A".

                        (b)   Plugging of Wells.  In the Storage Complex, the
            responsibility for the plugging of wells shall be as follows:

                              (i)   Within the Storage Complex boundaries shown
                  on Exhibit "A", after the date of the signing of this
                  Agreement, Companies shall have the right, at their sole
                  expense, to plug or replug any wells for mine through that
                  Companies determine in their sole discretion must be plugged
                  or replugged to permit the orderly progression of mining
                  within the mines.

                              (ii)   Except for: (A) wells which may be
                  released to TCO under Section  5.01(a)(iv); (B) wells which
                  may remain with TCO if Notice is not given pursuant to
                  Section  5.01(a)(v); (C) new wells drilled by TCO pursuant to
                  Section  5.01(d); and (D) well which may become the duty and
                  responsibility of TCO to plug pursuant to Section
                  4.03(b)(ii); as between Companies and TCO, Companies accept
                  the duty and sole responsibility under the applicable federal
                  and state statutes and regulations for the cost of and the
                  plugging of or replugging of wells (active storage wells as
                  well as abandoned wells) within the entire Storage Complex,
                  whether or not for mine through purposes.

                              (iii)  If this Agreement is terminated under
                  Section  10.01, all obligations of Companies to plug wells
                  under this Section  5.01(b) shall terminate immediately:
                  Provided, that with respect to any well theretofore plugged
                  or replugged by Companies, Companies shall remain liable for
                  the cost of plugging or replugging such well and the well
                  site restoration thereof.

                        (c)   Mine Maps.  Companies shall deliver to TCO two
            (2) copies of any mine map or plan or revision thereto respecting
            coal operations of Companies inside the perimeter of the Storage
            Complex within ten (10) days after filing the mine map or plan or
            revision thereto pursuant to 58 Pa. Cons.  Stat. Section
            601.302(b), or under any analogous West Virginia statute.

                        (d)   Prohibition of New Wells; Exception.  After the
            date of this Agreement, and to the extent TCO owns, leases,
            subleases, or directly or indirectly controls the underground
            storage rights or drilling rights, TCO shall maintain said rights
            and shall not permit others to drill new wells within the Storage
            Complex.  However, on a limited basis that does not interfere with
            near term mining, TCO reserves the right to drill new wells to be
            owned and operated by TCO, subject to the right of Companies to
            mine through any or all of the new wells pursuant to the applicable
            sections of this Agreement:  Provided, that TCO shall bear the
            entire cost of plugging any new well.

                        (e)   Recompletion of Wells.  Subject to the rights and
            obligations of the parties under this Article 5, TCO reserves the
            right to recomplete non-plugged existing storage wells (being only
            Injection-Withdrawal Wells, Observation Wells or Special Wells) to
            maximize the recovery of gas or to evaluate or to operate the
            Storage Fields:  Provided, that all recompletion work shall be
            limited to depths greater than two hundred (200) feet below the
            bottom of the Pittsburgh seam of coal.  All recompletion work shall
            be performed by TCO without any increase in cost, expense, amount
            paid or to be paid by Companies under this Agreement.

                        (f)   Cessation of Gas Withdrawal from a Well.  To
            primarily avoid delay in the orderly progression of mining and to
            secondarily maximize the withdrawal of stored gas:

                              (i)   Six (6) Month Notice of Plugging for Mine
                  Through.  Once Companies determine that mining or mining
                  impact will require any well [including new wells and
                  recompleted wells as described in Section 5.01(d) and (e)] to
                  be plugged for mine through in no less than six (6) months,
                  Companies shall deliver to TCO the following:  (A) a
                  six-month





                                       7

                  notice in writing of Companies' need to plug the well, and
                  (B), during the six (6) month notice period, for each well,
                  an "Assignment and Bill of Sale" for the well executed and
                  acknowledged by Companies in the form attached hereto and
                  made a part hereof as Exhibit "C" (hereafter "Assignment") .
                  The purpose of this extended notice period is to grant TCO,
                  without consideration, a longer period to produce the wells
                  while permits and bonds are being transferred.  However, even
                  if mining is not within six (6) months of an Observation
                  Well, Companies shall have the right, at their sole
                  discretion, to an assignment from TCO to plug same to reduce
                  pressures within the vicinity of mining.

                              (ii)  TCO's Delivery of an Assignment.   TCO
                  shall promptly execute, acknowledge, and return to Companies
                  any Assignment tendered by Companies pursuant to Section
                  5.01(f)(i)(B) above.  However, the warranties contained in
                  Section  6.01, Section  6.02, Section  6.03 and Section  6.07
                  as well as the indemnifications contained in Section  7.03
                  and Section  7.05 shall continue to apply to the well even
                  after same is assigned by TCO to Companies.  Further,
                  Companies do not in any way warrant the producability or
                  viability of the well and will not maintain it in any manner.
                  It is understood and agreed by the parties hereto that
                  Companies do not in any way assume any responsibilities or
                  obligations to any of the royalty interest owners of the
                  assigned premises or to anyone to whom TCO is obliged by any
                  existing agreements or contracts during or after the period
                  of operations by TCO.

                              (iii) Companies' Statutory Filings with the
                  States.  Upon TCO's return to Companies of a fully executed
                  and acknowledged Assignment, Companies shall notify the
                  proper state authority of transfer by promptly making the
                  statutory filing with the Commonwealth of Pennsylvania under
                  58 Pa. C.S.A. Section  601.213 or a successor statute, or
                  with the State of West Virginia under W. Va. Code Section
                  22B-1-26 (h) or a successor statute, as the case may be, so
                  that the well to be plugged will be released from TCO's bond
                  and secured under Companies' bond given under the law of the
                  state where the well is located.

                               (iv) Cleaning Up Well Sites before Plugging.
                  Immediately upon receipt of a six-month notice from Companies
                  as provided in Section 5.01 (f)(i), TCO shall do such work at
                  its own expense as may be necessary to render the affected
                  well site(s) environmentally clean and in compliance with all
                  applicable laws and regulations by the end of the six-month
                  notice period; and TCO shall thereafter keep the well site(s)
                  environmentally clean.  The purpose of the foregoing is to
                  assure that after Companies occupy the well site for the
                  purpose of plugging the well, Companies shall have no
                  subsequent expenses in connection with any prior
                  environmental contamination caused by the use or spill of
                  hazardous wastes or hazardous substances or any other
                  environmental hazard on the land within two hundred (200)
                  feet of any affected well site or emanating from the well
                  site.  The clean-up of a well site shall be to the extent
                  required, at the time the well bore is assigned and/or sold
                  to Companies, by the applicable Federal, State or Local
                  statutes, regulations and rules on account of oil and gas
                  (including gas storage) operations.  If TCO in its sole
                  discretion completes the clean-up and is ready to cease the
                  withdrawal of gas prior to the expiration of the six- month
                  notice delivered under Section  5.01(f)(i), TCO shall
                  promptly notify Companies of its readiness.

                              (v)   Fourteen (14) Day Cessation of Gas
                  Withdrawal.  By a fourteen (14) day notice in writing
                  delivered to TCO, Companies may direct that TCO shall cease
                  the withdrawal of gas from the assigned well on a date
                  certain, which date certain may be any day after the
                  expiration of the six-month notice period provided in Section
                  5.01(f)(i), so that Companies will be enabled to commence to
                  plug the well on the following day:  Provided, that TCO's
                  right to withdraw gas from the well may be extended
                  thereafter only if an extension is proposed by





                                       8
<PAGE>   13





                  Companies' field personnel and agreed to by TCO's field
                  personnel; and provided further, that a fourteen (14) day
                  notice shall not be necessary if TCO has notified Companies
                  of its readiness to cease the withdrawal of gas under Section
                  5.01(f)(iv).

                              (vi)  Accelerated Notice.  On a non-routine basis
                  and only when dictated by an unscheduled advancement of
                  mining operations, and when Companies and TCO have complied
                  with Section  5.01(f)(i), (ii) and (iii), then Companies may
                  give the fourteen (14) day notice even if six (6) months have
                  not expired to trigger the cessation of gas withdrawal and
                  the plugging specified in Section  5.01(f)(v).  Because of
                  the non- routine nature of this Notice, TCO shall be granted
                  a reasonable time to complete its clean-up pursuant to
                  Section  5.01(f)(iv).

                        (g)   Cleaning Up Well Sites and Assignments at
            Termination.  After the termination of Mining Operations pursuant
            to Section  10.02, TCO shall continue to do such work at its own
            expense as may be necessary to render all remaining well sites that
            Companies are obligated to plug under Section  5.01 environmentally
            clean so that they are in compliance with all then applicable
            federal, state or local statutes, regulations and rules, so as to
            assure that Companies shall have no subsequent expenses in
            connection with any prior environmental contamination caused by the
            use or spill of hazardous wastes or hazardous substances or any
            other environmental hazard on the land within two hundred (200)
            feet of a well site or emanating from a well bore and/or well site.
            The clean-up of the well sites and assignments of the wells shall
            be prioritized as follows:

                              (i)   For five (5) years after the termination of
                  mining operations, TCO shall clean up well sites in the order
                  specified by Companies as if the mining operations had not
                  terminated, that is to say, under the provisions of Section
                  5.01(f), except that the six (6) month notice required by
                  Section  5.01(f)(i) can be given at any time by Companies
                  since, at that point in time, the location of mining
                  operations will be irrelevant; and

                              (ii)  Five (5) years after such termination of
                  mining operations, if Companies have wells remaining to be
                  plugged, TCO shall clean up all of the remaining well sites
                  as soon as possible.  As the well sites are cleaned up, TCO
                  shall cease the withdrawal of gas, shut in the well, notify
                  Companies in writing that the clean-up has been completed,
                  and execute, acknowledge, and deliver to Companies an
                  Assignment for the well bore in the same form as provided in
                  Exhibit "C".  The Assignment shall thereafter be signed and
                  acknowledged by Companies, whereupon Companies shall
                  immediately make the statutory filing to comply with the
                  provisions of Section  5.01(f)(iii) for the well.  Provided,
                  that five (5) years after such termination of Mining
                  Operations,  Companies shall reimburse TCO's annual costs
                  incurred under Section  6.01 and Section  6.02 hereof
                  beginning with year six (6) after termination and continuing
                  until Companies, in their sole discretion, determine and
                  inform TCO in writing that such reimbursable costs incurred
                  by TCO are no longer necessary.

                              (iii)  The clean up of any well site after the
                  termination of Mining Operations pursuant to Section  10.02
                  shall be to the extent then required by the applicable
                  federal, state or local statutes, regulations and rules on
                  account of oil and gas (including gas storage) operations.
                  Further, as to any wells assigned to Companies pursuant to
                  this Section  5.01(g), TCO agrees and further covenants that
                  the warranties contained in Section  6.01, Section  6.02,
                  Section  6.03 and Section  6.07 as well as the
                  indemnifications contained in Section  7.03 and Section  7.05
                  shall survive the termination of this Agreement: Provided,
                  however, that as to this Section  5.01(g), the warranties
                  contained in Section  6.01, Section  6.02, and Section  6.03
                  shall be effective only until the end of the year in which
                  that particular well is plugged by Companies, or if more than
                  five (5) years after such termination of

                  mining operations, until Companies cease reimbursing TCO for
                  the costs of Section  6.01 and Section  6.02 as provided in
                  Section  5.01(g)(ii) above, whichever first occurs.

                  5.02  Responsibility for Costs.  Subject to the exceptions
            provided in this Section  5.02(b), (c), (d) and (e), TCO, as owner
            and operator, will bear and timely pay all costs of temporary
            deactivation and/or operation of the Storage Complex as follows:

                        (a)  Storage Complex Operations in General.  TCO shall
            timely pay all costs incurred in its deactivation and/or operation
            of the Storage Complex, including but not limited to:  (i) all
            costs associated with TCO's temporary deactivation and/or operation
            and maintenance of the Storage Complex, including the costs of any
            modifications or improvements (including new wells and
            recompletions of existing wells), capital or otherwise, necessary
            to operate the Storage Complex safely and to industry standards,
            including costs necessary to comply with all applicable statutes,
            regulations and rules of governmental entities having jurisdiction
            in the premises; (ii) all land acquisition costs, and all payments
            to lessors or sublessors or grantors of rights-of-way, including
            but not limited to acreage rental, storage acreage rental, well
            royalty, storage well royalty, oil royalty, as same are part of, or
            associated with, the Storage Complex; (iii) all free gas
            obligations to lessors, sublessors or landowners within the Storage
            Complex, and (iv) landowners' damage claims due to the unavoidable
            impact of TCO's construction or maintenance work, storage well and
            pipeline encroachment negotiations and litigation, legal services,
            operations planning, accounting services, and all reporting
            requirements relating to state and local authorities applicable to
            the temporary deactivation and/or operation of the Storage Complex.

                        (b)  Plugging Wells.  Except for: (i) wells which may
            be released to TCO under Section  5.01(a)(iv) hereof, (ii) wells
            which may remain with TCO if Notice is not given pursuant to
            Section  5.01(a)(v) hereof; (iii) new wells drilled by TCO pursuant
            to Section  5.01(d); and (iv) wells which may become the duty and
            responsibility of TCO to plug pursuant to Section  4.03(b)(ii); as
            between Companies and TCO, the work and associated costs of
            plugging and replugging of wells performed or to be performed by
            Companies under Section 5.01 and the well site restoration
            (excluding environmental clean up by TCO pursuant to Section
            4.01(f)(iv) or Section  4.01(g) prior to assignment of a well)
            after such plugging or replugging shall be borne solely by
            Companies, whether or not this Agreement has expired pursuant to
            Section  10.02: Provided, that if this Agreement is terminated
            under Section  10.01, all such obligations of Companies shall
            terminate immediately except that, with respect to any well
            theretofore plugged or replugged by Companies, Companies shall
            remain liable for the cost of plugging or replugging such well and
            the well site restoration.

                        (c)  Subsidence Damage to the Compressor Station.
            Prior to January 1, 2003, in any part of the area within a
            perimeter located two hundred (200) feet outside the existing fence
            surrounding the "Majorsville Compressor Station", Companies shall
            limit their underground mining to "development mining", that is, to
            underground entries driven at a width which should not cause damage
            to the surface above such entries.  Beyond the area within said
            perimeter, Companies may conduct full extraction mining.  The
            compressor station is located entirely within the State of West
            Virginia, and its general location is indicated on Exhibit "A", but
            Companies shall do the survey work necessary to locate the existing
            fence, the 200-foot perimeter, an inventory of the existing station
            and multiple site elevations for said Compressor Station.  Further,
            prior to January 1, 2003, all costs and expenses for temporary
            protection of or damage to the compressor station (that is, the
            compressor station as such and all ancillary structures and
            facilities involved in the suction of gas from the incoming
            pipelines, compression of gas in the compressors, and discharge of
            gas into outgoing pipelines, and the auxiliary office building all
            located within the fenced area referenced above) which exist on the
            date of the signing of this Agreement (specifically





                                       10

            excluding any future improvements) and which may be disturbed by
            subsidence due to mining operations shall be handled as follows:

                              (i)  The parties shall meet and discuss which of
                  the compressor station facilities may be disturbed and which
                  require mitigating action;

                              (ii)  If within the compressor station facility
                  mitigating action such as uncovering and blocking facilities
                  is taken by mutual consent, such costs shall be shared
                  equally by TCO and Companies;

                              (iii)  If, even with mitigating action, a
                  compressor station facility is materially damaged, such cost
                  of repair shall be shared equally by TCO and Companies;

                              (iv)  If both parties agree that mitigation is
                  required but disagree on the specific action, either may
                  invoke arbitration (under the Commercial Arbitration Rules of
                  the American Arbitration Association at a hearing site in
                  Pittsburgh, Pennsylvania), after which TCO shall take the
                  more costly mitigating action so as to minimize the risk of
                  damage to the compressor station facilities; and the
                  arbitration issue shall be limited to the cost difference
                  between the less costly and more costly mitigating actions;
                  and the prevailing party in arbitration shall not be
                  obligated to accept any of the burden of the cost difference
                  or the costs (except for filing fees) paid to the American
                  Arbitration Association.

                              (v)  If either party hereto rejects mitigation
                  proposed by the other, and material damage occurs, the
                  rejecting party will bear the entire cost of repairing the
                  subsidence-damaged compressor station facilities; and

                              (vi)  Any compressor station facilities which
                  break or rupture or are otherwise damaged by subsidence, but
                  which damage does not affect the economic injection and/or
                  withdrawal of the gas in the reservoirs of the Storage
                  Complex then being utilized shall be repaired, not repaired,
                  or otherwise dealt with at TCO's expense.

                              (vii)  The provisions of this Section  5.02(c)
                  shall not be deemed or construed to obligate Companies to pay
                  for any loss of gas resulting from damage to the compressor
                  station facilities caused by subsidence.

                              (viii)  Companies shall not be responsible for
                  any costs or expenses either for protection activities or for
                  damage to the compressor station which occur on or after
                  January 1, 2003 and which are caused by or related to
                  subsidence due to mining operations.

                        (d)  Subsidence Damage to Other Storage Complex
            Facilities.  With the exception of responsibility for certain costs
            and expenses at the Majorsville Compressor Station which occur
            prior to January 1, 2003 and as further described in Section
            5.02(c) above, Companies, after the date of this Agreement, shall
            neither have nor be deemed or construed to have any responsibility
            for any costs or expenses for either protection activities or for
            damage to any other Storage Complex facilities [including but not
            limited to pipelines, 248 wells used in the operation of the
            Storage Complex (whether Injection-Withdrawal, Observation, Special
            or other) and any other TCO appurtenances] or loss of gas therefrom
            which is caused by or related to subsidence due to mining
            operations.  Companies shall not have any duty to leave or provide
            subjacent or lateral support for the overlying strata or surface or
            anything thereon, therein or thereunder including but not limited
            to Storage Complex facilities now existing or hereafter erected.

                        (e)  Cleaning Up Well Sites.  Subject to any exceptions
            contained in Section  5.01(f)(iv) and (g), all costs and expenses
            for cleaning up well sites shall be borne by TCO.

                        (f)  Other Costs.  If not specifically mentioned in
            this Section 5.02, each party shall bear and timely pay the costs
            (including, but not limited to, those costs related to the
            Indemnifications provided in Article 7 as well as the costs for
            various reports, filings and legal expenses as referred to in
            Articles 3 and 8) as otherwise provided in this Agreement.


                   ARTICLE 6:  TCO'S WARRANTIES TO COMPANIES

                  6.01  Ownership Rights.  TCO has and, for the term of this
            Agreement, will maintain at its expense the necessary rights in the
            form of ownership, leases or licenses and all necessary permits to
            operate the Storage Complex and to assure that any activities
            necessary for performance of this Agreement by TCO (including but
            not limited to the operations of TCO and Companies as contemplated
            by Section 5.01) in the Storage Complex are controlled in the
            manner and for the time contemplated by this Agreement.

                  6.02  Rentals, Fees, Etc.  Payment of the annual rental shown
            on all leases and all other rents and fees necessary for the
            operation of the Storage Complex, is and, during the period of
            performance contemplated by this Agreement, will be maintained by
            TCO as current and complete.

                  6.03  Free Gas.  The right of any lessor, sublessor,
            landowner or other entity to free gas can be terminated at any
            time, without cost to Companies upon the plugging of the well(s) on
            the leasehold, and Companies shall have free and unrestricted
            access to the leaseholds for that purpose.  This warranty shall
            continue to apply even after TCO assigns ownership of a well to
            Companies.

                  6.04  Abandoned Wells.  TCO has made a diligent search to
            locate all abandoned wells within the Storage Complex and the
            results of such search are and will remain open for review by
            Companies.

                  6.05  Review of Data.  If requested by Companies, TCO will
            diligently work with Companies in any new review of available data
            that Companies may deem necessary in advance of their underground
            mining operations.

                  6.06  Wells Already Plugged.  Except for wells plugged by
            Companies, the plugging of all abandoned wells known to have
            penetrated any of the storage reservoirs within the Storage Complex
            is in compliance with Pennsylvania or West Virginia law, as the
            case may be, and as applicable at the time of plugging.

                  6.07  Polychlorinated Biphenyls.  As to wells plugged by
            Companies, TCO shall accept and remain responsible for any casing
            or tubing that is withdrawn from a well bore or surface wellhead
            equipment that is removed in order to plug the well, as long as
            such casing or tubing and surface wellhead equipment are subject to
            special handling requirements on account of possible PCB
            contamination.  Further, if any fluids withdrawn from the well in
            the plugging thereof are determined to be contaminated with PCBs,
            the disposal of the contaminated fluid shall be at TCO's cost and
            as TCO's responsibility.

                  6.08  Regulatory Approvals.  TCO warrants to Companies that
            the regulatory approvals required pursuant to Section  3.01(b)
            hereof will be adequate to permit TCO to perform its duties and
            obligations under this Agreement and that TCO will diligently
            comply with the terms and conditions of such regulatory approvals
            during the term of this Agreement.


                          ARTICLE 7:  INDEMNIFICATIONS

<PAGE>   17





                  7.01  Definitions.  For purposes of the indemnifications in
            this Article 7, the term "TCO" as indemnitee includes TCO's
            affiliated and subsidiary companies (past, present and future) and
            the officers, directors, employees, agents, and servants of each;
            and the term "Companies" as indemnitee includes CPC and NCC and GCC
            and their affiliated and subsidiary companies (past, present, and
            future), and the officers, directors, employees, agents, and
            servants of each.  However, the indemnitors shall be TCO as such
            and Companies as such, and not the affiliated and subsidiary
            companies, and the officers, directors, employees, agents and
            servants of each.

                  7.02  TCO's Indemnification by Companies.  Subject to the
            limitations and exceptions provided in this Section  7.02,
            Companies shall indemnify, defend and hold harmless TCO from and
            against any claim, loss, or liability (including punitive damages
            and civil and criminal penalties) for personal injury (including
            bodily injury and death) and/or for property damage to third
            parties relating directly or indirectly to the underground mining
            operations of Companies inside the boundary of the Storage Complex.
            This indemnification includes but is not limited to any claim, loss
            or liability based on third parties' allegations of--

                        (a)   Companies' negligent, willful, wanton, reckless or
                  deliberate act or omission; or

                        (b)   TCO's negligent act or omission which is joint or
                  concurrent (in time or sequence) with Companies' negligent,
                  willful, wanton, reckless or deliberate act or omission; or

                        (c)   TCO's sole negligent act or omission in failing
                  to locate abandoned wells within the perimeter of the Storage
                  Complex and/or in pressurizing additional gas sands not
                  currently part of the Storage Complex, but within the
                  perimeter of said Complex;

            and founded on any theory of law or equity whether grounded in the
            law of torts, contracts, property, or other substantive area of the
            law, including but not limited to theories based on fault, strict
            liability, absolute liability, statutory obligations, or otherwise.
            This indemnification specifically excludes and does not protect TCO
            against any claim, loss or liability for (i) loss of gas from
            wells, or from a storage reservoir, or from a pipeline, or payments
            of any type for the gas or the Storage Complex or any part of it;
            (ii) except as provided in Section  5.02(c), destruction of, loss
            of value of, or damage to the Storage Complex or any part of it;
            (iii) consequential damages resulting from loss of gas or loss of
            the Storage Complex or any part of it; and (iv) personal injury
            (including bodily injury and death) and/or property damage to third
            parties caused by gas escaping from damaged or broken pipelines
            and/or related pipeline facilities. Companies waive any right of
            contribution they may have against TCO or TCO's shareholders,
            officers, directors and employees with respect to the matters set
            forth in this Section  7.02.

                  7.03   Companies' Indemnification by TCO Respecting
            Environmental Matters.    TCO shall defend, indemnify, and hold
            harmless Companies from and against any claim, loss, liability,
            cost or expenses (including punitive damages and civil and criminal
            penalties) relating to any environmental harm or damage within or
            emanating from a well bore or land (during the period of temporary
            use and occupancy by Companies) within two hundred (200) feet of
            any well now or formerly operated by or plugged by TCO and which is
            assigned and/or sold to Companies pursuant to Section  5.01 (f)(ii)
            or Section  5.01 (g), except for and excluding any environmental
            harm or damage resulting from plugging and replugging of said wells
            by Companies, as well as site restoration of well sites associated
            with well plugging by Companies under this Agreement.  This
            indemnification shall include any and all claims, losses,
            liabilities, costs or expenses asserted or imposed against
            Companies (whether known or unknown at

            disposition of hazardous wastes and hazardous substances within or
            emanating from a well bore or land (during the period of temporary
            use and occupancy by Companies) within two hundred (200) feet of
            any well now or formerly operated by or plugged by TCO and which is
            assigned and/or sold to Companies pursuant to Section  5.01 (f)(ii)
            or Section  5.01 (g) of this Agreement, except for and excluding
            any environmental harm or damage resulting from plugging and
            replugging of wells by Companies under this Agreement, as well as
            site restoration of well sites associated with well plugging by
            Companies under this Agreement.  This indemnification shall also
            include any personal injury (including bodily injury or death) or
            property damage arising directly or indirectly from the presence of
            such hazardous wastes or substances or their clean-up or
            disposition.  This indemnification includes, but is not limited to,
            any action, obligation or liability under the Federal Comprehensive
            Environmental Response Compensation and Liability Act (commonly
            known as the Superfund Law or CERCLA), the Federal Resource
            Conservation and Recovery Act (commonly known as RCRA), the Toxic

            (including but not limited to any enacted or amended after the date
            of this Agreement); this indemnification shall not include any
            action, obligation or liability imposed by reason of the Surface
            Mine Reclamation Act, or any other federal or state statute
            (including any enacted after the date of this Agreement) applying
            to coal mine operations as distinguished from oil and gas
            operations.  This indemnification shall apply to all such actions,
            allegations or liabilities, whether brought, claimed or imposed by
            a federal, state or local governmental agency, by a private party,
            or by any other person or entity or combination of persons or
            entities and shall include without limitation actions based on
            strict liability or common law.  TCO waives any right of
            contribution it may have against Companies or Companies'
            shareholders, officers, directors and employees with respect to the
            matters set forth in this Section  7.03.  This indemnification
            shall include all circumstances and events existing at the time of
            this Agreement, and all releases to the environment by TCO before
            the termination or expiration of this Agreement.  However, the
            provisions of this Section  7.03 shall survive the termination of
            this Agreement.

                  7.04  Companies' Indemnification by TCO Respecting Article 6.
            TCO shall defend, indemnify, and hold harmless Companies from and
            against any claim, loss, liability, cost or expenses (including
            punitive damages and civil and criminal penalties) arising from or
            relating to any breach, inaccuracy, or other failure of any
            warranty given by TCO to Companies in Article 6.  This
            indemnification shall apply to all such claims, losses,
            liabilities, costs or expenses, whether asserted or imposed by a
            federal, state or local governmental agency, by a private party, or
            by any other person or entity or combination of persons or entities
            regardless of their nature or their basis in law or fact.  TCO
            waives any right of contribution it may have against Companies or
            Companies' shareholders, officers, directors and employees with
            respect to the matters set forth in this Section  7.04.

                  7.05  Companies' Indemnification by TCO Respecting a Well
            Operated after Assignment.  TCO agrees to indemnify and save
            harmless Companies against and from any and all claims made within
            the period of TCO's continued operation of a well or resulting
            thereafter from its operation of a well after an assignment of the
            well to Companies under Section  4.01(f), when claim is made by and
            on behalf of any person, firm, corporation, or governmental agency
            arising from or growing out of or in connection with operations on,
            in or with respect to the well, or arising out of property and
            rights hereby transferred or





                                       14

            assigned, and further, in case any action or proceeding is brought
            against Companies by reason of any such claim, TCO will, at its
            expense, resist and defend such action or proceeding and satisfy
            any order of judgment against Companies resulting therefrom.

                  7.06  Releases.  If either Companies or TCO obtain a release
            from any person for damages resulting from any event covered by the
            indemnifications in this Agreement, it shall not affect the
            respective rights and obligations of the parties under this Article
            7.

                  7.07  Representation of the Indemnitee.  The indemnified
            party hereunder shall be entitled at its option to representation
            by any attorney it selects, provided the attorney is acceptable to
            the other, which acceptance shall not be withheld except for good
            cause.  The indemnifying party shall pay all reasonable settlements
            of such claims, all judgments recovered in such claims, and the
            related costs of the defense, including consultants' and expert
            witnesses' fees and expenses, preparation of demonstrative evidence
            and other visual aids, plaintiff's attorney fees if awarded by
            judgment, and defense attorney fees and expenses for both parties.

                  7.08  Rule of Construction.  Subject to the limitations of
            Section 7.02, the indemnifications in this Article 7 shall be
            broadly construed to protect the indemnified party against any
            claim, loss, or liability to the extent that the law or public
            policy of the State or the United States does not expressly forbid
            indemnification.  In this connection, each waives its right to
            assert that any such law or public policy expressly forbids
            indemnification.

                  7.09  Limitations.  Indemnifications under this Article 7
            shall commence and be effective on the date of the signing of this
            Agreement, irrespective of the need for Bankruptcy Court or
            regulatory approval of the Agreement as a whole, unless both of the
            indivisible conditions specified in Section  3.01 do not occur as
            contemplated by this Agreement, so that the Agreement may be
            terminated.  In such event, and except as otherwise provided, the
            indemnifications shall be null and void as to matters occurring and
            claims made after the date that the Agreement is terminated.

                  7.10  Notice of Claims.  The indemnified party shall notify
            the other in writing, by certified mail, within fifteen (15) days
            after the receipt of any claim as to which that party believes it
            is indemnified.  However, notwithstanding failure to give notice
            under this Section  7.10, the indemnifications provided in this
            Article 7 shall apply if the failure was due to the party's
            inadvertence, provided such inadvertence does not prevent an
            adequate defense.


                      ARTICLE 8:  EXCHANGE OF INFORMATION.

                  8.01  Purpose of Exchange.  The parties will exchange
            information as provided in this Article 8 to facilitate the
            simultaneous withdrawal of gas and temporary deactivation of the
            Storage Complex by TCO and mining of coal by Companies.

                  8.02  TCO's Operations.  TCO will make available to Companies
            for review and evaluation any and all information in TCO's
            possession relating to (a) the deactivation, operation and
            maintenance of the Storage Complex and bearing on Companies' coal
            mining operations, and (b) the location and condition of all wells
            within the area encompassed by the Storage Complex.  In addition,
            TCO will permit Companies' designated consultants to inspect any
            facilities in the Storage Complex.

                  8.03  Companies' Operations.  Similarly, Companies will
            promptly make available to TCO for its review and evaluation not
            only its mine maps under Section  5.01(c), but also any and all
            information in Companies' possession which both relates to the
            operation and maintenance of its coal mines within the boundary of
            the Storage Complex and which has bearing on TCO's gas withdrawal





                                       15

            operations.  In addition, Companies will permit TCO or designated
            consultants to inspect Companies' facilities within the boundary of
            the Storage Complex.

                  8.04  Governmental Filings and Meetings.  In addition to the
            requirements for filings made pursuant to Article 3, at least ten
            (10) days prior to filing a major permit application or other major
            proposal for federal, state, or local governmental approval
            applicable to the operations of either party within the boundary of
            the Storage Complex, and any other major report or relevant major
            filing pursuant to any federal, state, or local laws, regulations
            or rules, the filing party shall give the other party an
            opportunity to review and propose revisions to the proposed filing.
            Further, after such major filing, the filing party shall furnish
            the other party with copies thereof.  Companies specifically shall
            have the right to participate in any conferences, and shall be kept
            informed by TCO of any communications between TCO and FERC Staff
            regarding TCO's temporary deactivation of the Storage Complex in
            accordance with the provisions of Article 5 and as set forth in
            further detail in Section  3.01(b) of this Agreement.

                  8.05  Quarterly Reports.  By the tenth (10th) day following
            the end of any quarter, the parties shall each provide the other
            with a quarterly report of its operations which are relevant to the
            operations of the other during the previous quarter, with the
            quarters ending on March 31, June 30, September 30 and December 31
            of each year.

                  9.01  Given in Writing.  All notices specified to be given

                  10.01  Termination for Failure of Two Indivisible Conditions.
            If either of the two (2) indivisible conditions set forth in
            Section  3.01 hereof is not satisfied or waived by January 1, 2003,
            unless extended by mutual written agreement of the parties, then
            either party may thereafter, at its option terminate this Agreement
            by giving sixty (60) days prior written notice to the other party
            of its intention to terminate, and unless both such conditions are
            satisfied during such sixty (60) day notice period or such notice
            is withdrawn, this Agreement shall terminate effective upon the
            expiration of such sixty (60) day notice period.

                  10.02  Termination Upon Completion of Mining Operations.
            Unless earlier terminated pursuant to Section  10.01 hereof or
            otherwise in accordance with the parties' rights under applicable
            law, this Agreement shall terminate twenty (20) years after the
            Effective Date, as defined in Section  2.01 hereof, unless
            Companies shall have given ninety (90) days written notice to TCO,
            prior to the expiration of such twenty (20) year period, that coal
            reserves remain to be mined by active mining operations of
            Companies within the boundaries of the Storage Complex, in which
            event this Agreement shall continue in effect thereafter until
            Companies shall have given TCO further written notice that such
            mining operations have been completed.

                  10.03  Survival of Obligations.  The obligations of the
            parties set forth in:  (a) Payment Conditions in Section  4.03
            hereof; (b) Plugging of wells in Section  5.01(b); (c) TCO's
            Warranties to Companies in Article 6 hereof, as limited by Section
            5.01(g)(iii); and (d) all of the indemnifications in Article 7
            hereof, which have arisen or become due prior to the date of
            termination of this Agreement for any reason, including those
            specified in this Article 10, shall survive such termination.


                     ARTICLE 11:  MISCELLANEOUS PROVISIONS

                  11.01  Governing Law.  This Agreement shall be governed by
            the laws of the Commonwealth of Pennsylvania.

                  11.02  Limited Effect of Agreement.  Neither party to this
            Agreement has indicated to the other party that the provisions of
            this Agreement are or may be suitable to apply to any future
            episodes, events, or situations involving other mines of Companies
            outside the Storage Complex boundaries or another of TCO's storage
            fields.  Each party covenants with the other that it will not cite
            any undertaking or other commitment by the other in this Agreement
            as expressing or implying a duty to make the same or a similar
            commitment in the future.

                  11.03  Severability.  Except for Section  3.01, if any
            article, section, paragraph, sentence or clause of this Agreement
            is adjudged to be invalid or unenforceable, such adjudication shall
            not affect the validity of the remaining portions of this
            Agreement; and, to this end, the provisions of this Agreement are
            hereby agreed to be severable.

                  11.04  Successors.  This Agreement shall be binding upon and
            inure to the benefit of the parties hereto and their successors and
            assigns.  An assignment shall not be deemed a novation, and the
            assignor shall remain primarily liable.


                  IN WITNESS WHEREOF, the parties hereto have caused their
            names to be signed hereto and their seals affixed all as of the day
            and year first above written.

            hereinafter referred to as "Companies", meaning each of them
            individually and severally and/or all of them collectively and
            jointly, as the context requires,

                                       A
                                        N

            hereinafter referred to as "BRC", the partners of which are CPC and
            GCC.

                 WHEREAS, TCO owns and operates three underground natural gas
            storage fields (being Heard Storage Field, the Majorsville Shallow
            Storage Field and the Majorsville Deep Storage Field), gas therein,
            wells, related storage pipelines and compressor facilities, and
            related 3000' reservoir protective areas, (hereinafter collectively
            referred to as the "Storage Complex") located in Greene and
            Washington Counties, Pennsylvania, as well as Marshall County, West
            Virginia; and

                 WHEREAS, the Companies currently own and/or operate coal
            mining operations in Greene and Washington Counties, Pennsylvania,
            as well as Marshall County, West Virginia; and,

                 WHEREAS, the partners of BRC currently own and/or operate coal
            mining operations in Greene and Washington Counties, Pennsylvania,
            as well as Marshall County, West Virginia; and,

                 WHEREAS, the Storage Complex and the mining operations
            underlie some of the same surface land which, at present, requires
            TCO, the Companies and BRC each to operate its respective
            facilities with due regard for the property, rights, and duties of
            the other; and,

                 WHEREAS, TCO and BRC have heretofore entered into agreements
            dated May 29, 1991 respecting their properties (the "Former
            Agreements" as hereinafter further defined); and

                 WHEREAS, on or about July 31, 1991, TCO filed for
            reorganization under Chapter 11 of the Federal Bankruptcy Code (11
            U.S.C. Section  101 et. seq.), which proceeding was filed on or
            about July 31, 1991 at Docket No. 91-804 pending in the United
            States Bankruptcy Court in the District of Delaware; and

                 WHEREAS, from the date of the execution of the Former
            Agreements until the date hereof, TCO and BRC have essentially
            complied with same, and TCO has neither assumed nor rejected the
            Former Agreements in its reorganization proceeding; however, TCO
            and BRC now believe that the Former Agreements may need to be
            modified to accomplish their business objectives, in light of both
            TCO's reorganization proceeding, and TCO's desire to comply with
            the Federal Energy Regulatory Commission ("FERC") Order No. 636;
            and
<PAGE>   26





                 WHEREAS, BRC, for good and valuable consideration, wishes to
            assign to the Companies all of its rights, title, interest, claims,
            duties and obligations under the Former Agreements; and

                 WHEREAS, TCO wishes to consent to this assignment by BRC to
            the Companies of all its rights, title, interest, claims, duties
            and obligations under the Former Agreements; and

                 WHEREAS, from the Effective Date (as hereinafter defined) of
            this Agreement, all the parties intend to suspend performance under
            the Former Agreements and simultaneously commence performance under
            the New Agreements (as hereinafter defined) which for so long as
            they remain effective, shall govern the respective rights, duties,
            obligations and liabilities of TCO and the Companies with respect
            to the temporary deactivation of the Storage Complex to accommodate
            mining operations; provided, however, that if the New Agreements
            are terminated based on failure of either of the two Indivisible
            Conditions (as hereinafter defined), the Former Agreements shall be
            reinstated as of the date of such termination.

                 NOW, THEREFORE, for and in consideration of the premises,
            which are incorporated and the mutual promises, covenants and
            agreements hereinafter set forth, TCO, the Companies and BRC, with
            intent to be legally bound, agree as follows:

                 2.03  Reinstatement of the Former Agreements.  If for any
            reason the Former Agreements are reinstated, then the Assignment of
            BRC to the Companies shall survive the termination of the New
            Agreements.


                    Article 3:  Reorganization Approval and Withdrawal of Claims

                 3.01  Application and Order.  TCO agrees that the form and

               Article 4:  Suspension and Contingent Rescission of the Former
                 Agreements

                 4.01  Suspension.  From the Effective Date of the New
            Agreements, each party shall accept performance under the New
            Agreements in full compliance with the provisions of the Former
            Agreements.  To that end, the Former Agreements are hereby
            suspended for so long as the New Agreements continue in effect and
            shall be reinstated in the event of termination of the New
            Agreements based on failure of either of the two Indivisible
            Conditions Precedent, as defined in Section  5.02 hereof.

                 4.02  Contingent Rescission.  Upon TCO's satisfying both the
            Indivisible Conditions as stated in Section  5.01 hereof, the
            Former Agreements shall be retroactively rescinded as of the
            Effective Date of this Agreement; provided, that, to the extent
            that TCO and BRC have performed pursuant to the Former Agreements,
            each accepts the performance of the other, and the Companies, BRC
            and TCO each accepts such performance to the same extent as if the
            New Agreements had been entered into on May 29, 1991, and all
            parties waive any claim of breach known or unknown, which may have
            arisen under the Former Agreements prior to the Effective Date of
            the New Agreements, subject to any rights and duties created by or
            arising out of (a) a breach in performance under the New Agreements
            or (b) TCO's filing on July 31, 1991 for reorganization under
            Chapter 11 of the Bankruptcy Code.

                 4.03  Effect of Future Performance.  In the event of any claim
            of breach of any provision of one or more of the Former Agreements,
            the faithful performance of the analogous duty under the New
            Agreements shall be a complete defense to the claim of breach.

           Article 5:  Indivisible Conditions to the New Agreements.

                 5.01  Two (2) Indivisible Conditions.  The two (2) indivisible
            conditions under the New Agreements shall be the same as set forth
            in Section  3.01 of the Second Master Agreement as that Agreement
            is referenced in Section  1.02(i) hereof.


                 Article 6:  Termination of the New Agreements

                 6.01  Termination.  The New Agreements shall terminate on the
            same basis set forth in Article 10 of the Second Master Agreement
            as that Agreement is referenced in Section  1.02 (i) hereof.

                              Article 7:  Notices

                 7.01  Given in Writing.  All notices and other communications

                 WHEREAS, Tennessee Gas Pipeline Company ("Tennessee") and

to any required authorizations by the Bankruptcy Court; and

                 WHEREAS, TCO and Tennessee acknowledge that TCO's customers

capacity assignments on upstream pipelines, pursuant to Section 284.242 of

FERC's Regulations; and

<PAGE>   2
                 WHEREAS, TCO intends to assign Contracts Nos. 2030 (a 15,637

Dth per day firm storage contract), 4872 (a 10,425 Dth per day firm

transportation contract) and a portion of its capacity under Contract No. 3871

(a 263,998 Dth per day firm transportation contract) to its customers upon

assumption in bankruptcy, as part of its own implementation of Order No. 636,

scheduled for November 1, 1993; and

                 WHEREAS, upon implementation of restructured services under

Order No. 636, TCO does not require certain capacity under Contract No. 3871 or

for any capacity under Contract No. 4870 (6,928 Dth per day), and has been

unable to assign such capacity to its customers; and

                 WHEREAS, TCO and Tennessee agree that the term "Excess

                 WHEREAS, TCO intends to retain Tennessee services under the

remaining Exhibit A Contracts for operational reasons; and

                 WHEREAS, TCO and Tennessee have agreed to an exit fee to be

calculated as specified below (the "Exit Fee") in consideration of TCO's

abandonment of Excess Capacity which will result from TCO's implementation of

Order No. 636; and

                 WHEREAS, TCO will use its Transportation Cost Rate Adjustment

mechanism (TCRA) to fully recover the Exit Fee from its customers pursuant to

                          Bremen and the Service Drilling gas purchase
                          contracts wherein Tennessee claims that TCO's
                          rejection of these contracts increased Tennessee's
                          obligation to purchase high cost gas ("Breach of
                          Contract Claim");


                 c)       Southwest Transportation Expenses ("Unpaid Invoices
                          Claim") in the amount of $4,782,854.80; and


                 d)       Gas Purchase Expenses ("Unpaid Invoices Claim") in
                          the amount of $428,598.42.

                 WHEREAS, by Stipulation and Settlement dated June 25, 1991

filed with and approved by FERC by orders dated April 10, 1992 and June 25,

1992, Tennessee is obligated to pay TCO a refund, including interest, based on

the reallocation of costs arising out of FERC Order No. 528, in three

semi-annual installments beginning in January 1993, which refund represents

overpayments received by Tennessee from TCO between July 1988 and October 1990

("Order No. 528 Refunds"); and

                 WHEREAS, Tennessee has made two payments of the Order No. 528

Refunds totalling $45,432,519.00; and

                 WHEREAS, on November 25, 1992, Tennessee filed a Motion for

Relief from Stay (the "Lift Stay Motion") seeking authority to set-off the

Unpaid Invoices Claims against the Order No. 528 Refunds; and

                 WHEREAS, on December 17, 1992, TCO and Tennessee entered into

a stipulation, which was So Ordered by the Bankruptcy Court on the same date

(the "Claims Stipulation"), providing for, inter alia, (i) liquidation of the

<PAGE>   4
Invoices Claims in the amount of $3,930,046.05, (ii) allowance of the Unpaid

Invoices Claims as allowed administrative expense priority claims, subject only

to any objection which might be made by the Official Customers' and Creditors'

Pennsylvania Office of Consumer Advocate, Ohio Consumer's Counsel, Columbia Gas

of Kentucky, Inc., Columbia Gas of Maryland, Inc., Columbia Gas of

Court of Appeals (the "Third Circuit") or the United States Supreme Court

reverses, remands, or vacates, in whole or in part, the Order of July 6, 1992

by the Federal District Court for the District of Delaware (the "District

Court") overturning the Bankruptcy Court's ruling on TCO's Omnibus FERC Motion

which was filed on August 23, 1991, and (iii) payment of the Unpaid Invoices

Claims upon confirmation of a plan of reorganization, or sooner upon Motion by

TCO on at least twenty (20) days notice to the Committees and any

Parties-in-Interest specifically requesting such notice; (iv) remedying the

transportation and exchange imbalances in the ordinary course of business,

pursuant to the Bankruptcy Court's Order of October 3, 1991; and

                 WHEREAS, on July 6, 1993 the Third Circuit issued a Memorandum

Decision which in fact overturned part of the District Court's ruling, holding

that refunds relating to prepetition periods (including FERC Order No. 528

Refunds) are trust monies which are not property of TCO's estate; and

                 WHEREAS, as part of TCO's assumption of the Exhibit A

contracts, TCO and Tennessee have agreed to the payment by TCO of the Unpaid

Invoices Claims as





                                       4

liquidated in the Claims Stipulation in full satisfaction of the requirement

that defaults under the Contracts be cured under 11 U.S.C. Section  365(b);

                  IT IS THEREFORE STIPULATED AND AGREED by the parties hereto

as follows:

                 1.  The Exhibit A contracts are hereby assumed by TCO.

                 2.  Upon assumption, the Exhibit A contracts will be amended

and conformed to comply with Tennessee's Order No. 636 implementation program

and will be fully or partially assignable to TCO's customers and to other

parties in accordance with Order No. 636, as it may be amended, modified or

superseded, and Tennessee's and TCO's approved FERC Gas Tariff, and subject to

applicable laws, rules, regulations, and orders of applicable regulatory

authorities.  Without limiting the foregoing, TCO shall have the right to

assign all or a portion of the transportation and/or storage capacity

underlying the Exhibit A contracts, on a permanent basis (assuming the

assignment is at the full contract rate for the remainder of the term of the

contract and that the assignee meets the creditworthiness standards contained

in the General Terms and Conditions of Tennessee's FERC Gas Tariff) to one or

more of TCO's customers or other parties in connection with TCO's and/or

Tennessee's restructuring under Order No. 636, and Tennessee agrees that any

permanent full or partial assignment(s) of capacity shall constitute an

assignment of the underlying Exhibit A contracts pursuant to 11 U.S.C. Section

365(f).  Accordingly, upon permanent assignment of capacity by TCO to customers

or other parties, TCO shall not, consistent with the provisions of 11 U.S.C.

Section 365 (k), have any liability for "breach of such [contracts] occurring

after such assignment(s)" with respect to the assigned capacity; provided,

however, that nothing herein shall affect (1) the right of Tennessee to recover

from TCO costs (a) which have been authorized by the FERC for service





                                       5

<PAGE>   6
periods predating the effective date of assignment of the underlying

contract(s), and (b) which are recoverable by Tennessee from TCO, consistent

with the terms of a FERC order, during that portion of the FERC-approved

recovery period predating the effective date of assignment of the underlying

contracts; and (2) the right of TCO to refunds from Tennessee for overpayments

made to Tennessee, as determined by the FERC, for services rendered to TCO by

Tennessee during periods which pre-date the effective date of assignment of the

underlying contract(s).

                 3.       Without limiting in any respect the provisions of

paragraph 2, TCO shall be entitled to the same rights and subject to the same

obligations under Tennessee's tariff and FERC orders as all other Tennessee

customers, including the right to participate in Tennessee's capacity release

and assignment program.

                 4.       Upon assumption, Contract No. 3871 shall be amended

to delete all of the Excess Capacity and Contract No.  4870 shall terminate,

subject to receipt of the Exit Fee.  In consideration of such amendment and

termination, TCO shall pay Tennessee the Exit Fee.  The Exit Fee shall be

calculated using the formula on Attachment A and using the Excess Capacity that

exists as of the first day of the month following the date the Stipulation

becomes effective pursuant to Paragraph Ten (10) herein. 1/

                 5.       TCO shall continue to make payments billed by and due

to Tennessee (including demand charges and FERC approved demand charge

surcharges) relating to the contracts listed on Exhibits A and B up to the date

which shall





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

1/       Assuming a January 1, 1994 effective date and 162,642  Dth per day of
         Excess Capacity, the  Exit Fee would be $42,147,209  in accordance
         with the Schedule on Attachment A.   Assuming a January 1, 1995
         effective date and  162,642 Dth per day of  Excess Capacity, the Exit
         Fee would be $36,650,591.

         be used for the purpose of calculating the Exit Fee in accordance with

the formula on Attachment A.

                 6.       TCO shall pay to Tennessee the amount of

$3,930,046.05 in full satisfaction of all arrearages owed by TCO to Tennessee

for pre-petition periods under the contracts and in satisfaction of the Unpaid

Invoice Claims.

                 7.       The Exhibit B contracts are hereby terminated by

agreement of the parties (subject to any necessary regulatory approvals), and

each party shall be deemed to have waived any claim for damages thereunder,

except for claims with respect to imbalances or post-petition unpaid invoices

due for services rendered up to the termination date which shall be remedied in

the normal course of business.  Tennessee's claim, with the exception of the

Breach of Contract Claim (in the amount of $14,294,820.00), is hereby amended

in accordance with this Stipulation.

                 8.       Nothing in this Stipulation shall diminish

Tennessee's obligation to make its remaining Order No. 528 Refunds (including

interest) described above to TCO.

                 9.       This Stipulation shall not be deemed an admission of

any fact or proposition of law, and shall not be used for any purpose other

than to the enforce the terms of this Stipulation.

                 10.      This Stipulation shall not be effective until the

later of January 1, 1994 or until the Stipulation is approved, executed and

entered by the Bankruptcy Court and FERC issues final orders, no longer subject

to rehearing, acceptable to TCO and Tennessee approving this Stipulation

including specifically (1) authorization for TCO to fully recover the Exit Fee

from its customers and (2) approval of Tennessee's proposed disposition of the

Exit Fee paid by TCO to Tennessee; provided, however, that TCO or Tennessee may

terminate this Stipulation upon 10 days written notice if such final orders

have not been issued





                                       7

by June 30, 1994.  If any Court should reverse in whole or in part the order of

the Bankruptcy Court or the final order of the FERC approving this Stipulation,

unless the parties agree in writing to the contrary, all monies paid by TCO to

Tennessee under Paragraphs 4 and 6, plus interest at the FERC's prescribed

rate, shall be returned to TCO, the status quo ante shall be restored and TCO

agrees to pay Tennessee all amounts due (including demand charges and FERC

approved demand surcharges) for any Excess Capacity to the extent not

remarketed at full contract rate between the date Excess Capacity is determined

pursuant to Paragraph 4 herein and the date Tennessee returns monies to TCO

pursuant to this paragraph, and TCO and Tennessee shall retain all rights to

assert claims, objections and other rights that are to be resolved by this

settlement, and no party can use this settlement as evidence against TCO or

Tennessee.  TCO shall have ten (10) days from the date the Stipulation becomes

effective to make the payments to Tennessee required herein.  Payments shall be

rendered in readily available funds at a bank designated by Tennessee.

                 11.      Nothing in this Stipulation shall be construed to

affect in any manner whatsoever any prior stipulation between the parties, or

any claim, except as specifically provided herein.

*        Although these contracts are not believed to be executory because of
         prior termination, they are still listed on Exhibit B to remove any
         uncertainty concerning their status since they are on TCO's Schedule G
         filed in the Bankruptcy Court as executory contracts.

WHEREAS

<PAGE>   4
clause; and

         WHEREAS, TCO and Texas Eastern wish to terminate the Exhibit B 

Contracts; and

         WHEREAS, TCO and Texas Eastern have agreed to compromise the amount of

arrearages which Texas Eastern claims are owed by TCO to Texas Eastern under

the Contracts for pre-petition periods for $3,432,776.34, plus any subsequent

interest at FERC-approved rates.

         IT IS THEREFORE STIPULATED AND AGREED by the parties hereto as follows:

         1.      TCO shall assume the Exhibit A Contracts.

         2.      Upon assumption, the Contracts will be amended and conformed

to comply with Texas Eastern's Order No. 636 implementation program and will be

fully or partially assignable in accordance with Order No. 636, as it may be

amended, modified or superseded, and Texas Eastern's and TCO's approved FERC

Gas Tariff, and subject to applicable laws, rules, regulations, and orders of

applicable regulatory authorities.  Without limiting the foregoing, TCO shall

have the right to assign all or a portion of the transportation and/or storage

capacity underlying the Contracts, on a temporary or permanent basis, to one or

more of TCO's customers or other parties in connection with TCO's and/or Texas

Eastern's restructuring under Order No. 636, and Texas Eastern agrees that any

permanent full or partial assignment(s) of capacity shall constitute an

assignment of the underlying Contracts pursuant to 11 U.S.C. Section 365(f).

Accordingly, upon permanent assignment of capacity by TCO to customers or other

parties, TCO shall not, consistent with the provisions of 11 U.S.C. Section

365(k), have any liability for "breach of such [contracts] occurring after such

assignment[s]" with respect to the assigned capacity; provided, however, that

TCO shall remain liable for claims billed or allocated to TCO under

FERC-approved rates for





                                       4

<PAGE>   5
services prior to assignment of the underlying Contracts.

         3.      TCO shall be entitled to the same rights and subject to the

same obligations under Texas Eastern's tariff and FERC orders as all other

Texas Eastern customers.

         4.      On the tenth day following the date the order approving this

Stipulation becomes final and non-appealable, TCO shall pay to Texas Eastern

the amount of $3,432,776.34 in settlement and full satisfaction of all

arrearages claimed by Texas Eastern to be owed by TCO to Texas Eastern for

pre-petition periods under the Exhibit A Contracts.  With respect to the Order

No. 94 settlement amounts, Texas Eastern shall refund TCO $18,747,217.11 and

TCO shall pay Texas Eastern $9,976,832 upon effectiveness of and in accordance

with the terms of the Order No. 94 settlement.

         5.      On the tenth day following the date that the order approving

this Stipulation becomes final and nonappealable, all of Texas Eastern's proofs

of claim against TCO shall be deemed withdrawn with prejudice.

         6.      On the tenth day following the date that the order approving

the settlement becomes final and nonappealable, the Setoff Motion and the

Motion to Compel shall be withdrawn as moot in light of TCO's assumption of the

Contracts and satisfaction of the claims asserted by Texas Eastern thereunder,

and except for the Order No. 94 refunds, Texas Eastern shall pay TCO the full

amount of the Refunds.  Texas Eastern shall assert no setoff or recoupment

against the Refunds for any claim arising prior to June 1, 1993, whether or not

asserted in the Setoff Motion.

         7.      On the tenth day following the date that the order approving

this Stipulation becomes final and nonappealable, the Exhibit B Contracts shall

be deemed terminated by agreement of the parties (subject to any necessary





                                       5

<PAGE>   6
regulatory approvals), and each party shall be deemed to have waived any claim

for damages thereunder.  Any remaining imbalances under these Contracts shall

be remedied in the ordinary course.

         8.      This Stipulation shall not be deemed an admission of any fact

or proposition of law, and shall not be used for any purpose other than to

enforce the terms of this Stipulation and Order entered approving this

Stipulation.  If the settlement as set forth in this Stipulation is not

approved in its entirety and without modification, unless the parties agree in

writing to the contrary, TCO and Texas Eastern retain all rights to assert

claims, objections and other rights that are to be resolved by this settlement,

and no party can use this settlement as evidence against TCO, Texas Eastern or

any other party in this proceeding.

the dependents, beneficiaries, and estate of the Employee shall be provided
with, the following:
         (a)     The Employee shall be paid the excess of:
                 (i)      the fixed salary that would otherwise have been

                          program in effect at such termination, calculated on
                          the assumption that any objectives for full payment
                          are obtained but not exceeded, less the amounts, if
                          any, the Employee would have paid in cash in respect

                          still employed, over
                 (ii)     the amounts, if any, paid to the Employee pursuant to
                          any retirement, severance, separation, or termination

                          its subsidiaries or affiliates.

                 Such payments shall commence with the month in which
                 termination shall have occurred, shall be made at the times
                 provided in paragraph 4(a) above, and shall continue for a
                 period of 12 months.

         (b)     The Employee shall also be paid the aggregate contributions or
                 payments, if any, that would have been made by the Company or
                 any of its subsidiaries or affiliates under the Thrift Plan
                 described in paragraph 4(b)(ii) above or any successor program
                 of the Company in effect on the date on which termination
                 shall have occurred, if the Employee had continued to be
                 employed, and to participate in the Thrift Plan or such
                 successor programs to the same extent as the Employee
                 participated for the last month during which the Employee was
                 permitted to participate, for a period of 12 months
                 thereafter, at an annual rate of compensation equal to that
                 used to calculate the payments provided by paragraph 8(a)
                 above.  Such payments shall be made at the times such
                 contributions would ordinarily have been made to the Thrift
                 Plan.

         (c)     For a period of 12 months (commencing with the month in which
                 termination shall have occurred), the Employee shall continue
                 to be entitled to all employee benefits provided for in
                 paragraphs 4(b)(iii) through (vii) above as if the Employee
                 were still employed during such period under this Agreement,
                 with benefits based upon the compensation used to calculate
                 the payments provided by paragraph 8(a) above, and if and to
                 the extent that such benefits shall not be payable or provided
                 under any such plan, the Company or any of its subsidiaries or
                 affiliates shall pay or provide such benefits on an individual
                 basis.  The benefits provided for in paragraph 4(b)(v) above
                 in accordance with this paragraph 8(c) shall be secondary to
                 any comparable benefits provided by another employer, provided
                 that an appropriate refund is made of any reduction in the
                 amount paid pursuant to paragraph 8(a)(i) which had assumed
                 that such benefits would be primary.

         (d)     The Employee and his beneficiary, if any, under the Retirement
                 Program described in paragraph 4(b)(i) above shall also be
                 paid the excess of:
                 (i)      the aggregate benefit that would have been paid under
                          the Retirement Program as in effect on the date first
                          above written, if the Employee had continued to be
                          employed and to be entitled to service credit for
                          eligibility and benefit purposes for a period of 12
                          months, at an annual rate of compensation equal to
                          that used to calculate the payments provided by
                          paragraph 8(a) above, calculated on the assumption
                          that the Employee is fully vested in such benefit,
                          over
                 (ii)     the aggregate benefit actually payable under the
                          Retirement Program and any successor retirement
                          program of the Company consisting of a tax-qualified
                          pension plan and a related excess benefit plan.
                 In clarification of the immediately preceding sentence, the
                 aggregate benefit that would have been paid under the
                 Retirement Program shall be calculated as of the normal or
                 early retirement date for which the Employee would have
                 qualified, if the Employee were still employed on that date,
                 and which would produce the highest benefit.  Such payments
                 shall commence on the date the Employee or his beneficiary, if
                 any, begins receiving payments under the Retirement Program,
                 shall be paid in the same form as under the Retirement Program
                 and shall continue until payments to the Employee and his
                 beneficiary, if any, cease under the Retirement Program.

         (e)     In the event that the Employee's Normal Retirement Date is
                 scheduled to occur during the 12-month period commencing with
                 the month in which the termination shall have occurred, the





                                      -12-

<PAGE>   13
                 payments and benefits provided for in paragraphs 8(a) through
                 (d) shall be based on the period commencing with such month
                 and ending with the month in which the Employee's Normal
                 Retirement Date occurs instead of said 12-month period,
                 regardless of whether the Company shall have extended the
                 Period of Employment beyond the Employee's Normal Retirement
                 Date pursuant to paragraph 3(a).

         (f)     In the event that the termination shall occur during the 12-
                 month period commencing on the occurrence, if any, of a Change
                 in Control, the Employee shall be paid, no later than 15 days
                 after the termination, a lump sum cash amount equal to the
                 present value of all amounts otherwise payable to the Employee
                 pursuant to paragraphs 8(a), (b) and (d) above, determined by
                 using a discount factor equal to the interest rate that would
                 have been used by the Pension Benefit Guaranty Corporation for
                 purposes of valuing immediate annuities under a pension plan
                 that terminated two months prior to the date on which
                 termination shall have occurred.

         (g)     To the extent that the Employee is entitled to receive cash
                 compensation that is (or would be, if any elective deferral
                 were disregarded) subject to Federal income taxation in
                 respect of other employment or a consulting position with
                 another company during the period upon which the payments and
                 benefits provided for in paragraphs 8(a) through (f) are
                 based, the payments to be made pursuant to such paragraphs
                 shall be correspondingly reduced, and, if necessary, the
                 Employee shall make an appropriate refund to the Company
                 without interest.

9.  Disclosure of Information
The Employee recognizes and acknowledges that the trade secrets and other
confidential or proprietary information of the Company and its subsidiaries and
affiliates are valuable, special and unique assets of the business of the
Company and its subsidiaries and affiliates, access to and knowledge of which
are essential to the performance of the Employee's duties under this Agreement.
The Employee will not, during or after the Period of Employment, in whole or in
part, disclose such secrets or information to any person, firm, corporation,
association or other entity (except the authorized representatives of the
Company or any of its subsidiaries or affiliates) for any reason or purpose
whatsoever, nor shall the Employee make use of any such secrets or information
for his own purposes or for the benefit of any person, firm, corporation,
association or other entity (except the Company and its subsidiaries and
affiliates) under any circumstances, whether during or after the Period of
Employment, except as required by law, authorized in writing by order of the
Board of Directors of the Company or necessary in the ordinary course of the
Employee's duties under this Agreement, provided that, after the Period of
Employment, these restrictions shall not apply to such secrets or information
that are then in the public domain (provided that the Employee was not, in
breach in this paragraph 9, responsible, directly or indirectly, for such
secrets or information entering the public domain). In the event of a breach or
threatened breach by the Employee of this paragraph 9, the Company shall be
entitled to injunctive relief; provided, however, that nothing in this
paragraph 9 or in paragraph 8 shall abrogate or prohibit the Company from
pursuing any other remedies available to it for such breach or threatened
breach, including, but not limited to, the recovery of actual or punitive
damages or both.

10.  Source of Payments
All payments provided for in paragraphs 4, 5, 6, 8, and 11 herein shall be paid

                                      -14-

<PAGE>   15
establish a special or separate fund or other segregation of assets to assure
such payments.

11.  Litigation Expenses; Arbitration
         (a)     In the event of any litigation or other proceeding between the
                 Company or any of its subsidiaries or affiliates and the
                 Employee with respect to the subject matter of this Agreement
                 and the enforcement of rights hereunder, the Employee shall be
                 reimbursed for all reasonable costs and expenses relating to
                 such litigation or other proceeding, including his reasonable
                 attorneys' fees and expenses, provided that such litigation or
                 proceeding results in any:

                 (i)      settlement requiring the Company or any of its
                          subsidiaries or affiliates to make a payment to the
                          Employee; or
                 (ii)     judgment or order in favor of the Employee,
                          regardless of whether such judgment or order is
                          subsequently reversed on appeal or in a collateral
                          proceeding.

                 In no event shall the Employee be required to reimburse the
                 Company or any of its subsidiaries or affiliates for any of
                 the costs and expenses relating to such litigation or other
                 proceeding.  The obligation of the Company or any of its
                 subsidiaries or affiliates under this paragraph 11 shall
                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

         (b)     In the event of any dispute or difference between the Company
                 or any of its subsidiaries or affiliates and the Employee with
                 respect to the subject matter of this Agreement and the
                 enforcement of rights hereunder, other than a dispute arising
                 under paragraph 9 above, the Employee may, in his sole
                 discretion by notice to the Company or any such subsidiary or
                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the
                 Employee had notified the Company or any of its subsidiaries
                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be
                 selected by the American Arbitration Association (the "AAA")
                 in Philadelphia, Pennsylvania, upon the application of the
                 Employee.  The determination reached in such arbitration shall
                 be final and binding on both parties without any right of
                 appeal or further dispute.  Execution of the determination by
                 such arbitrator or arbitrators may be sought in any court of
                 competent jurisdiction.  The arbitrators shall not be bound by
                 judicial formalities and may abstain from following the strict
                 rule of evidence and shall interpret this Agreement as an
                 honorable engagement and not merely as a legal obligation.
                 Unless otherwise agreed by the parties, any such arbitration
                 shall take place in Wilmington, Delaware, and shall be
                 conducted in accordance with the rules of the AAA.

not held so invalid, illegal or unenforceable, and each other provision or part
of a provision shall to the full extent consistent with law continue in full
force and effect.  If this Agreement is held invalid or cannot be enforced,
then to the full extent permitted by law any prior agreement between the
Company or any of its subsidiaries or affiliates and the Employee shall be
deemed reinstated as if this Agreement had not been executed.

15.  Consolidation, Merger, or Sale of Assets
Nothing in this Agreement shall preclude the Company or any of its subsidiaries
or affiliates from consolidating or merging into or with, or transferring all
or substantially all of its assets to, another corporation which assumes this
Agreement and all obligations and undertakings of the Company or any of its
subsidiaries or affiliates hereunder.  Upon such a consolidation, merger or
transfer of assets and assumption, the term, "the Company," as used herein
shall mean such other corporation and this Agreement shall continue in full
force and effect.

above, or in the event the Employee's employment under this Agreement is
terminated by the Company or any of its subsidiaries or affiliates for any
reason other than one of those specified in paragraphs 7(a) or 7(b) above,
then, subject to the Employee's compliance with the provisions of paragraph 9

be paid, as liquidated damages or severance pay, or both, and the Employee and
the dependents, beneficiaries, and estate of the Employee shall be provided
with, the following:

         (a)     The Employee shall be paid the excess of:
                 (i)      the fixed salary that would otherwise have been
                          provided in paragraph 4(a)(i) above, including the
                          increases therein provided, and any incentive
                          compensation and awards that would otherwise have
                          been payable under the provisions of any plan or
                          program in effect at such termination, calculated on
                          the assumption that any objectives for full payment
                          are obtained but not exceeded, less the amounts, if
                          any, the Employee would have paid in cash in respect
                          of employee benefits provided for in paragraphs
                          4(b)(iii) through (vii) above if the Employee were
                          still employed, over
                 (ii)     the amounts, if any, paid to the Employee pursuant to
                          any retirement, severance, separation, or termination
                          pay program or arrangement of the Company or any of
                          its subsidiaries or affiliates.

                 Such payments shall commence with the month in which
                 termination shall have occurred, shall be made at the times
                 provided in paragraph 4(a) above, and shall continue for a
                 period of 12 months.

         (b)     The Employee shall also be paid the aggregate contributions or
                 payments, if any, that would have been made by the Company or
                 any of its subsidiaries or affiliates under the Thrift Plan
                 described in paragraph 4(b)(ii) above or any successor program
                 of the Company in effect on the date on which termination
                 shall have occurred, if the Employee had continued to be
                 employed, and to participate in the Thrift Plan or such
                 successor programs to the same extent as the Employee
                 participated for the last month during which the Employee was
                 permitted to participate, for a period of 12 months
                 thereafter, at an annual rate of compensation equal to that
                 used to calculate the payments provided by paragraph 8(a)
                 above.  Such payments shall be made at the times such
                 contributions would ordinarily have been made to the Thrift
                 Plan.

         (c)     For a period of 12 months (commencing with the month in which
                 termination shall have occurred), the Employee shall continue
                 to be entitled to all employee benefits provided for in
                 paragraphs 4(b)(iii) through (vii) above as if the Employee
                 were still employed during such period under this Agreement,
                 with benefits based upon the compensation used to calculate
                 the payments provided by paragraph 8(a) above, and if and to
                 the extent that such benefits shall not be payable or provided
                 under any such plan, the Company or any of its subsidiaries or
                 affiliates shall pay or provide such benefits on an individual
                 basis.  The benefits provided for in paragraph 4(b)(v) above
                 in accordance with this paragraph 8(c) shall be secondary to
                 any comparable benefits provided by another employer, provided
                 that

                 an appropriate refund is made of any reduction in the amount 
                 paid pursuant to paragraph 8(a)(i) which had assumed that such 
                 benefits would be primary.

         (d)     The Employee and his beneficiary, if any, under the Retirement
                 Program described in paragraph 4(b)(i) above shall also be
                 paid the excess of:
                 (i)      the aggregate benefit that would have been paid under
                          the Retirement Program as in effect on the date first
                          above written, if the Employee had continued to be
                          employed and to be entitled to service credit for
                          eligibility and benefit purposes for a period of 12
                          months, at an annual rate of compensation equal to
                          that used to calculate the payments provided by
                          paragraph 8(a) above, calculated on the assumption
                          that the Employee is fully vested in such benefit,
                          over
                 (ii)     the aggregate benefit actually payable under the
                          Retirement Program and any successor retirement
                          program of the Company consisting of a tax-qualified
                          pension plan and a related excess benefit plan.
                 In clarification of the immediately preceding sentence, the
                 aggregate benefit that would have been paid under the
                 Retirement Program shall be calculated as of the normal or
                 early retirement date for which the Employee would have
                 qualified, if the Employee were still employed on that date,
                 and which would produce the highest benefit.  Such payments
                 shall commence on the date the Employee or his beneficiary, if
                 any, begins receiving payments under the Retirement Program,
                 shall be paid in the same form as under the Retirement Program
                 and shall continue until payments to the Employee and his
                 beneficiary, if any, cease under the Retirement Program.

         (e)     In the event that the Employee's Normal Retirement Date is
                 scheduled to occur during the 12-month period commencing with
                 the month in which the termination shall have occurred, the
                 payments and benefits provided for in paragraphs 8(a) through
                 (d) shall be based on the period commencing with such month
                 and ending with the month in which the Employee's Normal
                 Retirement Date occurs instead of said 12-month period,
                 regardless of whether the Company shall have extended the
                 Period of Employment beyond the Employee's Normal Retirement
                 Date pursuant to paragraph 3(a).

         (f)     In the event that the termination shall occur during the 12
                 month period commencing on the occurrence, if any, of a Change
                 in Control, the Employee shall be paid, no later than 15 days
                 after the termination, a lump sum cash amount equal to the
                 present value of all amounts otherwise payable to the Employee
                 pursuant to paragraphs 8(a), (b) and (d) above, determined by
                 using a discount factor equal to the interest rate that would
                 have been used by the Pension Benefit Guaranty Corporation for
                 purposes of valuing immediate annuities under a pension plan
                 that terminated two months prior to the date on which
                 termination shall have occurred.

         (g)     To the extent that the Employee is entitled to receive cash
                 compensation that is (or would be, if any elective deferral
                 were disregarded) subject to Federal income taxation in
                 respect of other employment or a consulting position with
                 another company during the period upon which the payments and
                 benefits provided for in paragraphs 8(a) through (f) are
                 based, the payments to be made pursuant to such paragraphs
                 shall be correspondingly reduced, and, if necessary, the
                 Employee shall make an appropriate refund to the Company
                 without interest.

9.  Disclosure of Information
The Employee recognizes and acknowledges that the trade secrets and other
confidential or proprietary information of the Company and its subsidiaries and
affiliates are valuable, special and unique assets of the business of the
Company and its subsidiaries and affiliates, access to and knowledge of which
are essential to the performance of the Employee's duties under this Agreement.
The Employee will not, during or after the Period of Employment, in whole or in
part, disclose such secrets or information to any person, firm, corporation,
association or other entity (except the authorized representatives of the
Company or any of its subsidiaries or affiliates) for any reason or purpose
whatsoever, nor shall the Employee make use of any such secrets or information
for his own purposes or for the benefit of any person, firm, corporation,
association or other entity (except the Company and its subsidiaries and
affiliates) under any circumstances, whether during or after the Period of
Employment, except as required by law, authorized in writing by order of the
Board of Directors of the Company or necessary in the ordinary course of the
Employee's duties under this Agreement, provided that, after the Period of
Employment, these restrictions shall not apply to such secrets or information
that are then in the public domain (provided that the Employee was not, in
breach in this paragraph 9, responsible, directly or indirectly, for such
secrets or information entering the public domain). In the event of a breach or
threatened breach by the Employee of this paragraph 9, the Company shall be
entitled to injunctive relief; provided, however, that nothing in this
paragraph 9 or in paragraph 8 shall abrogate or prohibit the Company from
pursuing any other remedies available to it for such breach or threatened
breach, including, but not limited to, the recovery of actual or punitive
damages or both.

10.  Source of Payments

establish a special or separate fund or other segregation of assets to assure
such payments.

11.  Litigation Expenses; Arbitration
         (a)     In the event of any litigation or other proceeding between the
                 Company or any of its subsidiaries or affiliates and the
                 Employee with respect to the subject matter of this Agreement
                 and the enforcement of rights hereunder, the Employee shall be
                 reimbursed for all reasonable costs and expenses relating to
                 such litigation or other proceeding, including his reasonable
                 attorneys' fees and expenses, provided that such litigation or
                 proceeding results in any:

                 (i)      settlement requiring the Company or any of its
                          subsidiaries or affiliates to make a payment to the
                          Employee; or

                 (ii)     judgment or order in favor of the Employee,
                          regardless of whether such judgment or order is
                          subsequently reversed on appeal or in a collateral
                          proceeding.

                 In no event shall the Employee be required to reimburse the
                 Company or any of its subsidiaries or affiliates for any of
                 the costs and expenses relating to such litigation or other
                 proceeding.  The obligation of the Company or any of its
                 subsidiaries or affiliates under this paragraph 11 shall
                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

         (b)     In the event of any dispute or difference between the Company
                 or any of its subsidiaries or affiliates and the Employee with
                 respect to the subject matter of this Agreement and the
                 enforcement of rights hereunder, other than a dispute arising
                 under paragraph 9 above, the Employee may, in his sole
                 discretion by notice to the Company or any such subsidiary or
                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the
                 Employee had notified the Company or any of its subsidiaries
                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be
                 selected by the American Arbitration Association (the "AAA")
                 in Philadelphia, Pennsylvania, upon the application of the
                 Employee.  The determination reached in such arbitration shall
                 be final and binding on both parties without any right of
                 appeal or further dispute.  Execution of the determination by
                 such arbitrator or arbitrators may be sought in any court of
                 competent jurisdiction.  The arbitrators shall not be bound by
                 judicial formalities and may abstain from following the strict
                 rule of evidence and shall interpret this Agreement as an
                 honorable engagement and not merely as a legal obligation.
                 Unless otherwise agreed by the parties, any such arbitration
                 shall take place in Wilmington, Delaware, and shall be
                 conducted in accordance with the rules of the AAA.

then to the full extent permitted by law any prior agreement between the
Company or any of its subsidiaries or affiliates and the Employee shall be
deemed reinstated as if this Agreement had not been executed.

15.  Consolidation, Merger, or Sale of Assets

                          of the Employee's duties under this Agreement,
                          including conviction for a felony or perpetration of

                          hereinafter defined), provided a successor

                          or affiliates, or to meetbona fide objectives and
                          qualifications duly promulgated as part of the

                          of its assets, other than a transaction in which a
                          successor corporation with a net worth at least equal
                          to that of the Company assumes this Agreement and all
                          obligations and undertakings of the Company
                          hereunder;
                 (ii)     reduction in the Employee's fixed salary or potential
                          incentive compensation or bonus under any plan or

                          objectives for full payment are attained but not
                          exceeded, except a proportionate reduction as part of

                          subsidiaries or affiliates; or
                 (iii)    at any time on or after the occurrence, if any, of a
                          Change in Control (as hereinafter defined), material
                          change by the Company or any of its subsidiaries or
                          affiliates of the Employee's functions or duties
                          which change would reduce the ranking or level,
                          responsibility, importance or scope of the Employee's
                          position with the Company or any of its subsidiaries

                 by written notice to the Company, specifying the event relied
                 upon for such termination and given within 180 days after such
                 event.

                 As used in this Agreement, "Change in Control" means the
happening of any of the following:
                 (i)      the acquisition by any party or parties of the
                          beneficial ownership of 25% or more of the voting

                          assets, or by merger, or otherwise, or
                 (iii)    the election during a period of 24 months, or less,
                          of 30% or more, of the members of the Board of
                          Directors of the Company, without the approval of a
                          majority of the Board of Directors as constituted at
                          the beginning of the period, or

8.  Payments Upon Termination of Employment
In the event of any termination by the Employee pursuant to paragraph 7(c)
above, or in the event the Employee's employment under this Agreement is
terminated by the Company or any of its subsidiaries or affiliates for any
reason other than one of those specified in paragraphs 7(a) or 7(b) above,
then, subject to the Employee's compliance with the provisions of paragraph 9
herein, and subject to paragraphs 8(e), (f), and (g) below, the Employee shall
be paid, as liquidated damages or severance pay, or both, and the Employee and
the dependents, beneficiaries, and estate of the Employee shall be provided
with, the following:

         (a)     The Employee shall be paid the excess of:
                 (i)      the fixed salary that would otherwise have been
                          provided in paragraph 4(a)(i) above, including the
                          increases therein provided, and any incentive





                                      -9-

<PAGE>   50
                          compensation and awards that would otherwise have
                          been payable under the provisions of any plan or
                          program in effect at such termination, calculated on
                          the assumption that any objectives for full payment
                          are obtained but not exceeded, less the amounts, if
                          any, the Employee would have paid in cash in respect
                          of employee benefits provided for in paragraphs
                          4(b)(iii) through (vii) above if the Employee were
                          still employed, over
                 (ii)     the amounts, if any, paid to the Employee pursuant to
                          any retirement, severance, separation, or termination
                          pay program or arrangement of the Company or any of
                          its subsidiaries or affiliates.
                 Such payments shall commence with the month in which
                 termination shall have occurred, shall be made at the times
                 provided in paragraph 4(a) above, and shall continue for a
                 period of 12 months.

         (b)     The Employee shall also be paid the aggregate contributions or
                 payments, if any, that would have been made by the Company or
                 any of its subsidiaries or affiliates under the Thrift Plan
                 described in paragraph 4(b)(ii) above or any successor program
                 of the Company in effect on the date on which termination
                 shall have occurred, if the Employee had continued to be
                 employed, and to participate in the Thrift Plan or such
                 successor programs to the same extent as the Employee
                 participated for the last month during which the Employee was
                 permitted to participate, for a period of 12 months
                 thereafter, at an annual rate of compensation equal to that
                 used to calculate the payments provided by paragraph 8(a)
                 above.  Such payments shall be made at the times such
                 contributions would ordinarily have been made to the Thrift
                 Plan.

         (c)     For a period of 12 months (commencing with the month in which
                 termination shall have occurred), the Employee shall continue





                                      -10-

<PAGE>   51
                 to be entitled to all employee benefits provided for in
                 paragraphs 4(b)(iii) through (vii) above as if the Employee
                 were still employed during such period under this Agreement,
                 with benefits based upon the compensation used to calculate
                 the payments provided by paragraph 8(a) above, and if and to
                 the extent that such benefits shall not be payable or provided
                 under any such plan, the Company or any of its subsidiaries or
                 affiliates shall pay or provide such benefits on an individual
                 basis.  The benefits provided for in paragraph 4(b)(v) above
                 in accordance with this paragraph 8(c) shall be secondary to
                 any comparable benefits provided by another employer, provided
                 that an appropriate refund is made of any reduction in the
                 amount paid pursuant to paragraph 8(a)(i) which had assumed
                 that such benefits would be primary.

         (d)     The Employee and his beneficiary, if any, under the Retirement
                 Program described in paragraph 4(b)(i) above shall also be
                 paid the excess of:
                 (i)      the aggregate benefit that would have been paid under
                          the Retirement Program as in effect on the date first
                          above written, if the Employee had continued to be
                          employed and to be entitled to service credit for
                          eligibility and benefit purposes for a period of 12
                          months, at an annual rate of compensation equal to
                          that used to calculate the payments provided by
                          paragraph 8(a) above, calculated on the assumption
                          that the Employee is fully vested in such benefit,
                          over
                 (ii)     the aggregate benefit actually payable under the
                          Retirement Program and any successor retirement
                          program of the Company consisting of a tax-qualified
                          pension plan and a related excess benefit plan.
                 In clarification of the immediately preceding sentence, the
                 aggregate benefit that would have been paid under the





                                      -11-

<PAGE>   52
                 Retirement Program shall be calculated as of the normal or
                 early retirement date for which the Employee would have
                 qualified, if the Employee were still employed on that date,
                 and which would produce the highest benefit.  Such payments
                 shall commence on the date the Employee or his beneficiary, if
                 any, begins receiving payments under the Retirement Program,
                 shall be paid in the same form as under the Retirement Program
                 and shall continue until payments to the Employee and his
                 beneficiary, if any, cease under the Retirement Program.

         (e)     In the event that the Employee's Normal Retirement Date is
                 scheduled to occur during the 12-month period commencing with
                 the month in which the termination shall have occurred, the
                 payments and benefits provided for in paragraphs 8(a) through
                 (d) shall be based on the period ending with said 12-month
                 period.

         (f)     In the event that the termination shall occur during the 12-
                 month period commencing on the occurrence, if any, of a Change
                 in Control, the Employee shall be paid, no later than 15 days
                 after the termination, a lump sum cash amount equal to the
                 present value of all amounts otherwise payable to the Employee
                 pursuant to paragraphs 8(a), (b) and (d) above, determined by
                 using a discount factor equal to the interest rate that would
                 have been used by the Pension Benefit Guaranty Corporation for
                 purposes of valuing immediate annuities under a pension plan
                 that terminated two months prior to the date on which
                 termination shall have occurred.

         (g)     To the extent that the Employee is entitled to receive cash
                 compensation that is (or would be, if any elective deferral
                 were disregarded) subject to Federal income taxation in
                 respect of other employment or a consulting position with
                 another company during the period upon which the payments and
                 benefits





                                      -12-

<PAGE>   53
                 provided for in paragraphs 8(a) through (f) are based, the
                 payments to be made pursuant to such paragraphs shall be
                 correspondingly reduced, and, if necessary, the Employee shall
                 make an appropriate refund to the Company without interest.

9.  Disclosure of Information
The Employee recognizes and acknowledges that the trade secrets and other
confidential or proprietary information of the Company and its subsidiaries and
affiliates are valuable, special and unique assets of the business of the
Company and its subsidiaries and affiliates, access to and knowledge of which
are essential to the performance of the Employee's duties under this Agreement.
The Employee will not, during or after the Period of Employment, in whole or in
part, disclose such secrets or information to any person, firm, corporation,
association or other entity (except the authorized representatives of the
Company or any of its subsidiaries or affiliates) for any reason or purpose
whatsoever, nor shall the Employee make use of any such secrets or information
for his own purposes or for the benefit of any person, firm, corporation,
association or other entity (except the Company and its subsidiaries and
affiliates) under any circumstances, whether during or after the Period of
Employment, except as required by law, authorized in writing by order of the
Board of Directors of the Company or necessary in the ordinary course of the
Employee's duties under this Agreement, provided that, after the Period of
Employment, these restrictions shall not apply to such secrets or information
that are then in the public domain (provided that the Employee was not, in
breach in this paragraph 9, responsible, directly or indirectly, for such
secrets or information entering the public domain). In the event of a breach or
threatened breach by the Employee of this paragraph 9, the Company shall be
entitled to injunctive relief; provided, however, that nothing in this
paragraph 9 or in paragraph 8 shall abrogate or prohibit the Company from
pursuing any other remedies available to it for such breach or threatened
breach, including, but not limited to, the recovery of actual or punitive
damages or both.

10.  Source of Payments
All payments provided for in paragraphs 4, 5, 6, 8, and 11 herein shall be paid





                                      -13-

The Company, or its subsidiaries or affiliates, shall not be required to
establish a special or separate fund or other segregation of assets to assure
such payments.

11.  Litigation Expenses; Arbitration
         (a)     In the event of any litigation or other proceeding between the
                 Company or any of its subsidiaries or affiliates and the
                 Employee with respect to the subject matter of this Agreement
                 and the enforcement of rights hereunder, the Employee shall be
                 reimbursed for all reasonable costs and expenses relating to
                 such litigation or other proceeding, including his reasonable
                 attorneys' fees and expenses, provided that such litigation or
                 proceeding results in any:

                 (i)      settlement requiring the Company or any of its
                          subsidiaries or affiliates to make a payment to the
                          Employee; or

                 (ii)     judgment or order in favor of the Employee,
                          regardless of whether such judgment or order is
                          subsequently reversed on appeal or in a collateral
                          proceeding.

                 In no event shall the Employee be required to reimburse the
                 Company or any of its subsidiaries or affiliates for any of
                 the costs and expenses relating to such litigation or other
                 proceeding.  The obligation of the Company or any of its
                 subsidiaries or affiliates under this paragraph 11 shall
                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

         (b)     In the event of any dispute or difference between the Company
                 or any of its subsidiaries or affiliates and the Employee with
                 respect to the subject matter of this Agreement and the
                 enforcement of rights hereunder, other than a dispute arising
                 under paragraph 9 above, the Employee may, in his sole
                 discretion by notice to the Company or any such subsidiary or
                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the
                 Employee had notified the Company or any of its subsidiaries
                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be
                 selected by the American Arbitration Association (the "AAA")
                 in Philadelphia, Pennsylvania, upon the application of the
                 Employee.  The determination reached in such arbitration shall
                 be final and binding on both parties without any right of
                 appeal or further dispute.  Execution of the determination by
                 such arbitrator or arbitrators may be sought in any court of
                 competent jurisdiction.  The arbitrators shall not be bound by
                 judicial formalities and may abstain from following the strict
                 rule of evidence and shall interpret this Agreement as an
                 honorable engagement and not merely as a legal obligation.
                 Unless otherwise agreed by the parties, any such arbitration
                 shall take place in Wilmington, Delaware, and shall be
                 conducted in accordance with the rules of the AAA.

                          its subsidiaries or affiliates for which senior

                 provided, however, that nothing in this Agreement shall
                 preclude the Company or any of its subsidiaries or affiliates
                 from amending or terminating any such plan or program, on the

                          successor corporation with a net worth at least equal
                          to that of the Company assumes this Agreement and all

                          affiliates of the Employee's functions or duties
                          which change would reduce the ranking or level,
                          responsibility, importance or scope of the Employee's
                          position with the Company or any of its subsidiaries

                          majority of the Board of Directors as constituted at

8.  Payments Upon Termination of Employment
In the event of any termination by the Employee pursuant to paragraph 7(c)
above, or in the event the Employee's employment under this Agreement is
terminated by the Company or any of its subsidiaries or affiliates for any
reason other than one of those specified in paragraphs 7(a) or 7(b) above,
then, subject to the Employee's compliance with the provisions of paragraph 9
herein, and subject to paragraphs 8(e), (f), and (g) below, the Employee shall
be paid, as liquidated damages or severance pay, or both, and the Employee and
the dependents, beneficiaries, and estate of the Employee shall be provided
with, the following:

         (a)     The Employee shall be paid the excess of:
                 (i)      the fixed salary that would otherwise have been
                          provided in paragraph 4(a)(i) above, including the
                          increases therein provided, and any incentive
                          compensation and awards that would otherwise have
                          been payable under the provisions of any plan or
                          program in effect at such termination, calculated on
                          the assumption that any objectives for full payment
                          are obtained but not exceeded, less the amounts, if
                          any, the Employee would have paid in cash in respect
                          of employee benefits provided for in paragraphs
                          4(b)(iii) through (vii) above if the Employee were





                                      -10-

<PAGE>   70
                          still employed, over
                 (ii)     the amounts, if any, paid to the Employee pursuant to
                          any retirement, severance, separation, or termination
                          pay program or arrangement of the Company or any of
                          its subsidiaries or affiliates.

                 Such payments shall commence with the month in which
                 termination shall have occurred, shall be made at the times
                 provided in paragraph 4(a) above, and shall continue for a
                 period of 12 months.

         (b)     The Employee shall also be paid the aggregate contributions or
                 payments, if any, that would have been made by the Company or
                 any of its subsidiaries or affiliates under the Thrift Plan
                 described in paragraph 4(b)(ii) above or any successor program
                 of the Company in effect on the date on which termination
                 shall have occurred, if the Employee had continued to be
                 employed, and to participate in the Thrift Plan or such
                 successor programs to the same extent as the Employee
                 participated for the last month during which the Employee was
                 permitted to participate, for a period of 12 months
                 thereafter, at an annual rate of compensation equal to that
                 used to calculate the payments provided by paragraph 8(a)
                 above.  Such payments shall be made at the times such
                 contributions would ordinarily have been made to the Thrift
                 Plan.

         (c)     For a period of 12 months (commencing with the month in which
                 termination shall have occurred), the Employee shall continue
                 to be entitled to all employee benefits provided for in
                 paragraphs 4(b)(iii) through (vii) above as if the Employee
                 were still employed during such period under this Agreement,
                 with benefits based upon the compensation used to calculate
                 the payments provided by paragraph 8(a) above, and if and to
                 the





                                      -11-

<PAGE>   71
                 extent that such benefits shall not be payable or
                 provided under any such plan, the Company or any of its
                 subsidiaries or affiliates shall pay or provide such benefits
                 on an individual basis.  The benefits provided for in
                 paragraph 4(b)(v) above in accordance with this paragraph 8(c)
                 shall be secondary to any comparable benefits provided by
                 another employer, provided that an appropriate refund is made
                 of any reduction in the amount paid pursuant to paragraph
                 8(a)(i) which had assumed that such benefits would be primary.

         (d)     The Employee and his beneficiary, if any, under the Retirement
                 Program described in paragraph 4(b)(i) above shall also be
                 paid the excess of:
                 (i)      the aggregate benefit that would have been paid under
                          the Retirement Program as in effect on the date first
                          above written, if the Employee had continued to be
                          employed and to be entitled to service credit for
                          eligibility and benefit purposes for a period of 12
                          months, at an annual rate of compensation equal to
                          that used to calculate the payments provided by
                          paragraph 8(a) above, calculated on the assumption
                          that the Employee is fully vested in such benefit,
                          over
                 (ii)     the aggregate benefit actually payable under the
                          Retirement Program and any successor retirement
                          program of the Company consisting of a tax-qualified
                          pension plan and a related excess benefit plan.
                 In clarification of the immediately preceding sentence, the
                 aggregate benefit that would have been paid under the
                 Retirement Program shall be calculated as of the normal or
                 early retirement date for which the Employee would have
                 qualified, if the Employee were still employed on that date,





                                      -12-

                 and which would produce the highest benefit.  Such payments
                 shall commence on the date the Employee or his beneficiary, if
                 any, begins receiving payments under the Retirement Program,
                 shall be paid in the same form as under the Retirement Program
                 and shall continue until payments to the Employee and his
                 beneficiary, if any, cease under the Retirement Program.

         (e)     In the event that the Employee's Normal Retirement Date is
                 scheduled to occur during the 12-month period commencing with
                 the month in which the termination shall have occurred, the
                 payments and benefits provided for in paragraphs 8(a) through
                 (d) shall be based on the period commencing with such month
                 and ending with the month in which the Employee's Normal
                 Retirement Date occurs instead of said 12-month period,
                 regardless of whether the Company shall have extended the
                 Period of Employment beyond the Employee's Normal Retirement
                 Date pursuant to paragraph 3(a).

         (f)     In the event that the termination shall occur during the 12-
                 month period commencing on the occurrence, if any, of a Change
                 in Control, the Employee shall be paid, no later than 15 days
                 after the termination, a lump sum cash amount equal to the
                 present value of all amounts otherwise payable to the Employee
                 pursuant to paragraphs 8(a), (b), and (d) above, determined by
                 using a discount factor equal to the interest rate that would
                 have been used by the Pension Benefit Guaranty Corporation for
                 purposes of valuing immediate annuities under a pension plan
                 that terminated two months prior to the date on which
                 termination shall have occurred.

         (g)     To the extent that the Employee is entitled to receive cash
                 compensation that is (or would be, if any elective deferral





                                      -13-

                 were disregarded) subject to Federal income taxation   in
                 respect of other employment or a consulting position with
                 another company during the period upon which the payments and
                 benefits provided for in paragraphs 8(a) through (f) are
                 based, the payments to be made pursuant to such paragraphs
                 shall be correspondingly reduced, and, if necessary, the
                 Employee shall make an appropriate refund to the Company
                 without interest.

9.  Disclosure of Information
The Employee recognizes and acknowledges that the trade secrets and other
confidential or proprietary information of the Company and its subsidiaries and
affiliates are valuable, special and unique assets of the business of the
Company and its subsidiaries and affiliates, access to and knowledge of which
are essential to the performance of the Employee's duties under this Agreement.
The Employee will not, during or after the Period of Employment, in whole or in
part, disclose such secrets or information to any person, firm, corporation,
association or other entity (except the authorized representatives of the
Company or any of its subsidiaries or affiliates) for any reason or purpose
whatsoever, nor shall the Employee make use of any such secrets or information
for his own purposes or for the benefit of any person, firm, corporation,
association or other entity (except the Company and its subsidiaries and
affiliates) under any circumstances, whether during or after the Period of
Employment, except as required by law, authorized in writing by order of the
Board of Directors of the Company or necessary in the ordinary course of the
Employee's duties under this Agreement, provided that, after the Period of
Employment, these restrictions shall not apply to such secrets or information
that are then in the public domain (provided that the Employee was not, in
breach in this paragraph 9, responsible, directly or indirectly, for such
secrets or information entering the public domain). In the event of a breach or
threatened breach by the Employee of this paragraph 9, the Company shall be
entitled to injunctive relief; provided, however, that nothing in this
paragraph 9 or in paragraph 8 shall abrogate or prohibit the Company from
pursuing any other remedies available to it for such





                                      -14-

breach or threatened breach, including, but not limited to, the recovery of
actual or punitive damages or both.

10.  Source of Payments
All payments provided for in paragraphs 4, 5, 6, 8, and 11 herein shall be paid

The Company, or its subsidiaries or affiliates, shall not be required to
establish a special or separate fund or other segregation of assets to assure
such payments.

11.  Litigation Expenses; Arbitration
         (a)     In the event of any litigation or other proceeding between the
                 Company or any of its subsidiaries or affiliates and the
                 Employee with respect to the subject matter of this Agreement
                 and the enforcement of rights hereunder, the Employee shall be
                 reimbursed for all reasonable costs and expenses relating to
                 such litigation or other proceeding, including his reasonable
                 attorneys' fees and expenses, provided that such litigation or
                 proceeding results in any:

                 (i)      settlement requiring the Company or any of its
                          subsidiaries or affiliates to make a payment to the
                          Employee; or

                 (ii)     judgment or order in favor of the Employee,
                          regardless of whether such judgment or order is
                          subsequently reversed on appeal or in a collateral
                          proceeding.

                 In no event shall the Employee be required to reimburse the
                 Company or any of its subsidiaries or affiliates for any of





                                      -15-

<PAGE>   75
                 the costs and expenses relating to such litigation or other
                 proceeding.  The obligation of the Company or any of its
                 subsidiaries or affiliates under this paragraph 11 shall
                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

         (b)     In the event of any dispute or difference between the Company
                 or any of its subsidiaries or affiliates and the Employee with
                 respect to the subject matter of this Agreement and the
                 enforcement of rights hereunder, other than a dispute arising
                 under paragraph 9 above, the Employee may, in his sole
                 discretion by notice to the Company or any such subsidiary or
                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the
                 Employee had notified the Company or any of its subsidiaries
                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be
                 selected by the American Arbitration Association (the "AAA")
                 in Philadelphia, Pennsylvania, upon the application of the
                 Employee.  The determination reached in such arbitration shall
                 be final and binding on both parties without any right of
                 appeal or further dispute.  Execution of the determination by
                 such arbitrator or arbitrators may be sought in any court of
                 competent jurisdiction.  The arbitrators shall not be bound by
                 judicial formalities and may abstain from following the strict
                 rule of evidence and shall interpret this Agreement as an
                 honorable engagement and not merely as a legal obligation.
                 Unless otherwise agreed by the parties, any such arbitration





                                      -16-

                 (ii)     such incentive compensation and bonus, if any, as may
                          be awarded to the Employee from time to time by the
                          Board of Directors of the Company or by a committee
                          designated by said Board in accordance

                          Company or any of its subsidiaries or affiliates in

                          or shut-down) of any subsidiary, affiliate, division
                          or district of the Company with which the Employee
                          was employed for a reasonable time prior to the

                          hereinafter defined), provided a successor

                          or affiliates, or to meetbona fide objectives and
                          qualifications duly promulgated as part of the
                          customary personnel practices of the Company or any
                          of its subsidiaries or affiliates;
                 by written notice to the Employee, specifying the event relied
                 upon for such termination and given within 180 days after such
                 event;

         (b)     by either the Company or any of its subsidiaries or

                          to that of the Company assumes this Agreement and all
                          obligations and undertakings of the Company
                          hereunder;
                 (ii)     reduction in the Employee's fixed salary
                          or potential incentive compensation or bonus under
                          any plan or program, calculated on the assumption
                          that any objectives for full payment are attained but
                          not exceeded, except a proportionate reduction as
                          part of a wage and salary reduction program affecting

                          breach of this Agreement by the Company or any of its
                          subsidiaries or affiliates; or
                 (iii)    at any time on or after the occurrence, if any, of a
                          Change in Control (as hereinafter defined), material

                          affiliates of the Employee's functions or duties
                          which change would reduce the ranking or level,
                          responsibility, importance or scope of the Employee's
                          position with the Company or any of its subsidiaries
                          or affiliates;
                 by written notice to the Company, specifying the event relied
                 upon for such termination and given within 180 days after such
                 event.

                 As used in this Agreement, "Change in Control" means the
happening of any of the following: 
                 (i)      the acquisition by any party or parties of the 
                          beneficial ownership of 25% or more of the voting

                 (iii)    the election during a period of 24 months, or less,
                          of 30% or more, of the members of the Board of
                          Directors of the Company, without the approval of a
                          majority of the Board of Directors as constituted at
                          the beginning of the period, or

8.  Payments Upon Termination of Employment
In the event of any termination by the Employee pursuant to paragraph 7(c)
above, or in the event the Employee's employment under this Agreement is
terminated by the Company or any of its subsidiaries or affiliates for any
reason other than one of those specified in paragraphs 7(a) or 7(b) above,
then, subject to the Employee's compliance with the provisions of paragraph 9
herein, and subject to paragraphs 8(e), (f), and (g) below, the Employee shall
be paid, as liquidated damages or severance pay, or both, and the Employee and
the dependents, beneficiaries, and estate of the Employee shall be provided
with, the following:

         (a)     The Employee shall be paid the excess of:
                 (i)      the fixed salary that would otherwise have been
                          provided in paragraph 4(a)(i) above, including the
                          increases therein provided, and any incentive
                          compensation and awards that would otherwise have
                          been payable under the provisions of any plan or
                          program in effect at such termination, calculated on
                          the assumption that any objectives for full payment
                          are obtained but not exceeded, less the amounts, if
                          any, the Employee would have paid in cash in respect
                          of employee benefits provided for in paragraphs
                          4(b)(iii) through (vii) above if the Employee were
                          still employed, over
                 (ii)     the amounts, if any, paid to the Employee pursuant to
                          any retirement, severance, separation or





                                      -10-

<PAGE>   91
                          termination pay program or arrangement of the Company 
                          or any of its subsidiaries or affiliates.

                 Such payments shall commence with the month in which
                 termination shall have occurred, shall be made at the times
                 provided in paragraph 4(a) above, and shall continue for a
                 period of 12 months.

         (b)     The Employee shall also be paid the aggregate contributions or
                 payments, if any, that would have been made by the Company or
                 any of its subsidiaries or affiliates under the Thrift Plan
                 described in paragraph 4(b)(ii) above or any successor program
                 of the Company in effect on the date on which termination
                 shall have occurred, if the Employee had continued to be
                 employed, and to participate in the Thrift Plan or such
                 successor programs to the same extent as the Employee
                 participated for the last month during which the Employee was
                 permitted to participate, for a period of 12 months
                 thereafter, at an annual rate of compensation equal to that
                 used to calculate the payments provided by paragraph 8(a)
                 above.  Such payments shall be made at the times such
                 contributions would ordinarily have been made to the Thrift
                 Plan.

         (c)     For a period of 12 months (commencing with the month in which
                 termination shall have occurred), the Employee shall continue
                 to be entitled to all employee benefits provided for in
                 paragraphs 4(b)(iii) through (vii) above as if the Employee
                 were still employed during such period under this Agreement,
                 with benefits based upon the compensation used to calculate
                 the payments provided by paragraph 8(a) above, and if and to
                 the extent that such benefits shall not be payable or provided
                 under any such plan, the Company or any of its subsidiaries or
                 affiliates shall pay or provide such benefits on an individual





                                      -11-

<PAGE>   92
                 basis.  The benefits provided for in paragraph 4(b)(v) above
                 in accordance with this paragraph 8(c) shall be secondary to
                 any comparable benefits provided by another employer, provided
                 that an appropriate refund is made of any reduction in the
                 amount paid pursuant to paragraph 8(a)(i) which had assumed
                 that such benefits would be primary.

         (d)     The Employee and his beneficiary, if any, under the Retirement
                 Program described in paragraph 4(b)(i) above shall also be
                 paid the excess of:
                 (i)      the aggregate benefit that would have been paid under
                          the Retirement Program as in effect on the date first
                          above written, if the Employee had continued to be
                          employed and to be entitled to service credit for
                          eligibility and benefit purposes for a period of 12
                          months, at an annual rate of compensation equal to
                          that used to calculate the payments provided by
                          paragraph 8(a) above, calculated on the assumption
                          that the Employee is fully vested in such benefit,
                          over
                 (ii)     the aggregate benefit actually payable under the
                          Retirement Program and any successor retirement
                          program of the Company consisting of a tax-qualified
                          pension plan and a related excess benefit plan.
                 In clarification of the immediately preceding sentence, the
                 aggregate benefit that would have been paid under the
                 Retirement Program shall be calculated as of the normal or
                 early retirement date for which the Employee would have
                 qualified, if the Employee were still employed on that date,
                 and which would produce the highest benefit.  Such payments
                 shall commence on the date the Employee or his beneficiary, if
                 any, begins receiving payments under the Retirement Program,





                                      -12-

<PAGE>   93
                 shall be paid in the same form as under the Retirement Program
                 and shall continue until payments to the Employee and his
                 beneficiary, if any, cease under the Retirement Program.

         (e)     In the event that the Employee's Normal Retirement Date is
                 scheduled to occur during the 12-month period commencing with
                 the month in which the termination shall have occurred, the
                 payments and benefits provided for in paragraphs 8(a) through
                 (d) shall be based on the period commencing with such month
                 and ending with the month in which the Employee's Normal
                 Retirement Date occurs instead of said 12-month period,
                 regardless of whether the Company shall have extended the
                 Period of Employment beyond the Employee's Normal Retirement
                 Date pursuant to paragraph 3(a).

         (f)     In the event that the termination shall occur during the 12
                 month period commencing on the occurrence, if any, of a Change
                 in Control, the Employee shall be paid, no later than 15 days
                 after the termination, a lump sum cash amount equal to the
                 present value of all amounts otherwise payable to the Employee
                 pursuant to paragraphs 8(a), (b) and (d) above, determined by
                 using a discount factor equal to the interest rate that would
                 have been used by the Pension Benefit Guaranty Corporation for
                 purposes of valuing immediate annuities under a pension plan
                 that terminated two months prior to the date on which
                 termination shall have occurred.

         (g)     To the extent that the Employee is entitled to receive cash
                 compensation that is (or would be, if any elective deferral
                 were disregarded) subject to Federal income taxation in
                 respect of other employment or a consulting position with
                 another company during the period upon which the payments and
                 benefits

                 provided for in paragraphs 8(a) through (f) are based, the
                 payments to be made pursuant to such paragraphs shall be
                 correspondingly reduced, and, if necessary, the Employee shall
                 make an appropriate refund to the Company without interest.
         (h)     In the event the Employee's employment is terminated prior to
                 the expiration of any extension of this Agreement because of a
                 disability, or because of or Change of Control as defined in
                 paragraph 7(c), or because the Employee is terminated by the
                 Company or any of its subsidiaries or affiliates for a reason
                 other than those specified in paragraphs 7(a) or 7(b), the
                 Employee shall be entitled to (a) continue to participate in
                 the Company's medical and dental benefits programs in

                 Company's active and retired employees, and (b) receive a
                 special supplemental payment from the Company in the amount of
                 $2,500.00 a month, beginning on the first day of the month
                 following twelve full calendar months after such termination,
                 and ending on the last day of the month in which the
                 Employee's death occurs or the last day of the month in which
                 the Employee attains age 55, whichever is the earlier.

<PAGE>   96
                 (i)      settlement requiring the Company or any of its

                 (ii)     judgment or order in favor of the Employee,

                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the

                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be

                          be awarded to the Employee from time to time by the
                          Board of Directors of the Company or by a committee
                          designated by said Board in accordance

                          Company or any of its subsidiaries or affiliates in

                 at the time of such confirmation.  In the event the Employee's

                          was employed for a reasonable time prior to the

                          hereinafter defined), provided a successor

                          or affiliates, or to meetbona fide objectives and
                          qualifications duly promulgated as part of the
                          customary personnel practices of the Company or any
                          of its subsidiaries or affiliates;

                 upon for such termination and given within 180 days after such
                 event;

                          equal to that of the Company assumes this Agreement 
                          and all obligations and undertakings of the Company
                          hereunder;
                 (ii)     reduction in the Employee's fixed salary
                          or potential incentive compensation or bonus under
                          any plan or program, calculated on the assumption
                          that any objectives for full payment are attained but
                          not exceeded, except a proportionate reduction as
                          part of a wage and salary reduction program affecting
                          the Company's employees generally, or other material
                          breach of this Agreement by the Company or any of its
                          subsidiaries or affiliates; or
                 (iii)    at any time on or after the occurrence, if any, of a
                          Change in Control (as hereinafter defined), material

                          affiliates of the Employee's functions or duties
                          which change would reduce the ranking or level,
                          responsibility, importance or scope of the Employee's
                          position with the Company or any of its subsidiaries
                          or affiliates;
                 by written notice to the Company, specifying the event relied
                 upon for such termination and given within 180 days after such
                 event.

                 As used in this Agreement, "Change in Control" means the
happening of any of the following:

                 (i)      the acquisition by any party or parties of the
                          beneficial ownership of 25% or more of the voting

                 (iii)    the election during a period of 24 months, or less, 
                          of 30% or more, of the members of the Board of

                          majority of the Board of Directors as constituted at
                          the beginning of the period, or

8.  Payments Upon Termination of Employment
In the event of any termination by the Employee pursuant to paragraph 7(c)
above, or in the event the Employee's employment under this Agreement is
terminated by the Company or any of its subsidiaries or affiliates for any
reason other than one of those specified in paragraphs 7(a) or 7(b) above,
then, subject to the Employee's compliance with the provisions of paragraph 9
herein, and subject to paragraphs 8(e), (f), and (g) below, the Employee shall
be paid, as liquidated damages or severance pay, or both, and the Employee and
the dependents, beneficiaries, and estate of the Employee shall be provided
with, the following:
         (a)     The Employee shall be paid the excess of:
                 (i)      the fixed salary that would otherwise have been
                          provided in paragraph 4(a)(i) above, including the
                          increases therein provided, and any incentive
                          compensation and awards that would otherwise have
                          been payable under the provisions of any plan or
                          program in effect at such termination, calculated on
                          the assumption that any objectives for full payment
                          are obtained but not exceeded, less the amounts, if
                          any, the Employee would have paid in cash in respect
                          of employee benefits provided for in paragraphs
                          4(b)(iii) through (vii) above if the Employee were
                          still employed, over





                                      -10-

<PAGE>   112
                 (ii)     the amounts, if any, paid to the Employee pursuant to
                          any retirement, severance, separation or termination
                          pay program or arrangement of the Company or any of
                          its subsidiaries or affiliates.

                 Such payments shall commence with the month in which
                 termination shall have occurred, shall be made at the times
                 provided in paragraph 4(a) above, and shall continue for a
                 period of 12 months.

         (b)     The Employee shall also be paid the aggregate contributions or
                 payments, if any, that would have been made by the Company or
                 any of its subsidiaries or affiliates under the Thrift Plan
                 described in paragraph 4(b)(ii) above or any successor program
                 of the Company in effect on the date on which termination
                 shall have occurred, if the Employee had continued to be
                 employed, and to participate in the Thrift Plan or such
                 successor programs to the same extent as the Employee
                 participated for the last month during which the Employee was
                 permitted to participate, for a period of 12 months
                 thereafter, at an annual rate of compensation equal to that
                 used to calculate the payments provided by paragraph 8(a)
                 above.  Such payments shall be made at the times such
                 contributions would ordinarily have been made to the Thrift
                 Plan.

         (c)     For a period of 12 months (commencing with the month in which
                 termination shall have occurred), the Employee shall continue
                 to be entitled to all employee benefits provided for in
                 paragraphs 4(b)(iii) through (vii) above as if the Employee
                 were still employed during such period under this Agreement,
                 with benefits based upon the compensation used to calculate
                 the payments provided by paragraph 8(a) above, and if and to
                 the extent that such benefits shall not be payable or provided

<PAGE>   113
                 under any such plan, the Company or any of its subsidiaries or
                 affiliates shall pay or provide such benefits on an individual
                 basis.  The benefits provided for in paragraph 4(b)(v) above
                 in accordance with this paragraph 8(c) shall be secondary to
                 any comparable benefits provided by another employer, provided
                 that an appropriate refund is made of any reduction in the
                 amount paid pursuant to paragraph 8(a)(i) which had assumed
                 that such benefits would be primary.

         (d)     The Employee and his beneficiary, if any, under the Retirement
                 Program described in paragraph 4(b)(i) above shall also be
                 paid the excess of: 
                 (i)      the aggregate benefit that would have been paid under
                          the Retirement Program as in effect on the date first
                          above written, if the Employee had continued to be
                          employed and to be entitled to service credit for
                          eligibility and benefit purposes for a period of 12
                          months, at an annual rate of compensation equal to
                          that used to calculate the payments provided by
                          paragraph 8(a) above, calculated on the assumption
                          that the Employee is fully vested in such benefit,
                          over
                 (ii)     the aggregate benefit actually payable under the
                          Retirement Program and any successor retirement
                          program of the Company consisting of a tax-qualified
                          pension plan and a related excess benefit plan.
                 In clarification of the immediately preceding sentence, the
                 aggregate benefit that would have been paid under the
                 Retirement Program shall be calculated as of the normal or
                 early retirement date for which the Employee would have
                 qualified, if the Employee were still employed on that date,
                 and which would produce the highest benefit.  Such payments

<PAGE>   114
                 shall commence on the date the Employee or his beneficiary, if
                 any, begins receiving payments under the Retirement Program,
                 shall be paid in the same form as under the Retirement Program
                 and shall continue until payments to the Employee and his
                 beneficiary, if any, cease under the Retirement Program.

         (e)     In the event that the Employee's Normal Retirement Date is
                 scheduled to occur during the 12-month period commencing with
                 the month in which the termination shall have occurred, the
                 payments and benefits provided for in paragraphs 8(a) through
                 (d) shall be based on the period commencing with such month
                 and ending with the month in which the Employee's Normal
                 Retirement Date occurs instead of said 12-month period,
                 regardless of whether the Company shall have extended the
                 Period of Employment beyond the Employee's Normal Retirement
                 Date pursuant to paragraph 3(a).

         (f)     In the event that the termination shall occur during the 12
                 month period commencing on the occurrence, if any, of a Change
                 in Control, the Employee shall be paid, no later than 15 days
                 after the termination, a lump sum cash amount equal to the
                 present value of all amounts otherwise payable to the Employee
                 pursuant to paragraphs 8(a), (b) and (d) above, determined by
                 using a discount factor equal to the interest rate that would
                 have been used by the Pension Benefit Guaranty Corporation for
                 purposes of valuing immediate annuities under a pension plan
                 that terminated two months prior to the date on which
                 termination shall have occurred.

         (g)     To the extent that the Employee is entitled to receive cash
                 compensation that is (or would be, if any elective deferral
                 were disregarded) subject to Federal income taxation in
                 respect

                 of other employment or a consulting position with another
                 company during the period upon which the payments and benefits
                 provided for in paragraphs 8(a) through (f) are based, the
                 payments to be made pursuant to such paragraphs shall be
                 correspondingly reduced, and, if necessary, the Employee shall
                 make an appropriate refund to the Company without interest.

         (h)     In the event the Employee's employment is terminated prior to
                 the expiration of any extension of this Agreement because of a
                 disability, or because of or Change of Control as defined in
                 paragraph 7(c), or because the Employee is terminated by the
                 Company or any of its subsidiaries or affiliates for a reason
                 other than those specified in paragraphs 7(a) or 7(b), the
                 Employee shall be entitled to (a) continue to participate in
                 the Company's medical and dental benefits programs in
                 accordance with the terms and conditions applicable to the
                 Company's active and retired employees, and (b) receive a
                 special supplemental payment from the Company in the amount of
                 $2,500.00 a month, beginning on the first day of the month
                 following twelve full calendar months after such termination,
                 and ending on the last day of the month in which the
                 Employee's death occurs or the last day of the month in which
                 the Employee attains age 55, whichever is the earlier.
9.  Disclosure of Information

confidential or proprietary information of the Company and its subsidiaries and
affiliates are valuable, special and unique assets of the business of the

part, disclose such secrets or information to any person, firm, corporation,

purposes or for the benefit of any person, firm, corporation, association or
other entity (except the Company and its subsidiaries and affiliates) under any
circumstances, whether during or after the Period of Employment, except as
required by law, authorized in writing by order of the Board of Directors of
the Company or necessary in the ordinary course of the Employee's duties under
this Agreement, provided that, after the Period of Employment, these
restrictions shall not apply to such secrets or information that are then in
the public domain (provided that the Employee was not, in breach in this
paragraph 9, responsible, directly or indirectly, for such secrets or
information entering the public domain). In the event of a breach or threatened
breach by the Employee of this paragraph 9, the Company shall be entitled to
injunctive relief; provided, however, that nothing in this paragraph 9 or in
paragraph 8 shall abrogate or prohibit the Company from pursuing any other
remedies available to it for such breach or threatened breach, including, but
not limited to, the recovery of actual or punitive damages or both.

10.  Source of Payments

                 Employee with respect to the subject matter of this Agreement
                 and the enforcement of rights hereunder, the Employee shall be
                 reimbursed for all reasonable costs and expenses relating to
                 such litigation or other proceeding, including his reasonable
                 attorneys'





                                      -15-

<PAGE>   117
                 fees and expenses, provided that such litigation or proceeding
                 results in any:

                 (i)      settlement requiring the Company or any of its
                          subsidiaries or affiliates to make a payment to the
                          Employee; or

                 (ii)     judgment or order in favor of the Employee,
                          regardless of whether such judgment or order is
                          subsequently reversed on appeal or in a collateral
                          proceeding.

                 In no event shall the Employee be required to reimburse the
                 Company or any of its subsidiaries or affiliates for any of
                 the costs and expenses relating to such litigation or other
                 proceeding.  The obligation of the Company or any of its
                 subsidiaries or affiliates under this paragraph 11 shall
                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

         (b)     In the event of any dispute or difference between the Company
                 or any of its subsidiaries or affiliates and the Employee with
                 respect to the subject matter of this Agreement and the
                 enforcement of rights hereunder, other than a dispute arising
                 under paragraph 9 above, the Employee may, in his sole
                 discretion by notice to the Company or any such subsidiary or
                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the





                                      -16-

<PAGE>   118
                 Employee had notified the Company or any of its subsidiaries
                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be
                 selected by the American Arbitration Association (the "AAA")
                 in Philadelphia, Pennsylvania, upon the application of the
                 Employee.  The determination reached in such arbitration shall
                 be final and binding on both parties without any right of
                 appeal or further dispute.  Execution of the determination by
                 such arbitrator or arbitrators may be sought in any court of
                 competent jurisdiction.  The arbitrators shall not be bound by
                 judicial formalities and may abstain from following the strict
                 rule of evidence and shall interpret this Agreement as an
                 honorable engagement and not merely as a legal obligation.
                 Unless otherwise agreed by the parties, any such arbitration
                 shall take place in Wilmington, Delaware, and shall be
                 conducted in accordance with the rules of the AAA.

its subsidiaries or affiliates and the Employee with respect to the subject

or any of its subsidiaries or affiliates and the Employee, except that this
Agreement shall not affect or operate to reduce any benefit or compensation
inuring to the Employee of a kind elsewhere provided and not expressly provided

                         W I T N E S S E T H    T H A T

                 WHEREAS, the Employee is a valuable employee of a subsidiary
of the Company and an integral part of its management who participates in the

the Company; and

                 WHEREAS, the Compensation Committee of the Board of Directors
of the Company, at a meeting held on June 16, 1993, determined that it would be
in the best interests of the Company and its shareholders to assure continuity
in the management of the Company's administration and operations by entering
into an employment agreement to retain the services of the Employee containing
such terms and conditions necessary to maintain the Employee's total
compensation, benefits and terms of employment relative to the Company's
business and geographic area; and

                 WHEREAS, the Company wishes to assure itself of the continued
services of the Employee for the period hereinafter provided, and the Employee
is willing to continue in the employ of the Company or any of its subsidiaries
or affiliates on a full- time basis for said period, upon the other terms and
conditions provided in this Agreement;

                 NOW THEREFORE, it is hereby agreed by and between the parties
hereto as follows:

1.  Employment
The Company agrees to continue the Employee in its employ, or in the employ of
any of its subsidiaries or affiliates, and the Employee agrees to remain in the

Employment (as hereinafter defined) and upon the other terms and conditions
herein provided.


2.  Position and Responsibilities
During the Period of Employment, the Employee agrees to serve the Company or
any of its subsidiaries or affiliates in such executive capacity or capacities
as the Board of Directors, the Chairman of the Board of Directors and Chief

3.  Term and Duties
         (a)     The period of the Employee's employment under this Agreement
                 shall be from the first date written above through the date of
                 confirmation by the U.S. Bankruptcy Court for the District of
                 Delaware of the Chapter 11 reorganization plan of Columbia Gas
                 Transmission Corporation (Case No. 91-804), subject to
                 extension by agreement of the Company and the Employee (the
                 "Period of Employment"); provided, however, that the Period of
                 Employment shall cease on the Employee's normal retirement
                 date ("Normal Retirement Date") under the Company's Retirement
                 Program [as defined in paragraph 4(b)(i) below] unless the

                 incapacity and reasonable vacation periods, the Employee's
                 business time, attention, skill and efforts shall be

<PAGE>   126
                 nothing in this Agreement shall preclude the Employee from
                 devoting time during reasonable periods required for: 
                 (i)      serving as an officer, director or member of a 
                          committee of any company or organization involving no
                          conflict of interest with the Company or any of its
                          subsidiaries or affiliates, and subject to Company
                          approval as is normal for such activities,

                 (iii)    engaging in charitable and community activities,
                          provided that such activities do not materially
                          affect or interfere with the performance of the
                          Employee's obligations to the Company or any of its
                          subsidiaries or affiliates.

4.  Compensation
         (a)     For all services rendered by the Employee in any capacity
                 during the Period of Employment, including services as an
                 executive, officer, director, or member of any committee of
                 the Company or any of its subsidiaries or affiliates, the
                 Employee shall be paid as compensation: 
                 (i)      a fixed salary at the rate of not less than $222,645  
                          per year, subject to such periodic increases as the
                          Board of Directors of the Company, or a committee
                          designated by said Board, shall deem appropriate in
                          accordance with the customary procedures and
                          practices of the Company or any of its subsidiaries
                          or affiliates regarding the salaries of senior
                          management employees, and

                          Company or any of its subsidiaries or affiliates in

                          or affiliates, or to meetbona fide objectives and

                          successor corporation with a net worth at least equal
                          to that of the Company assumes this Agreement and all

                          affiliates of the Employee's functions or duties
                          which change would reduce the ranking or level,
                          responsibility, importance or scope of the Employee's
                          position with the Company or any of its subsidiaries

8.  Payments Upon Termination of Employment
In the event of any termination by the Employee pursuant to paragraph 7(c)
above, or in the event the Employee's employment under this Agreement is
terminated by the Company or any of its subsidiaries or affiliates for any
reason other than one of those specified in paragraphs 7(a) or 7(b) above,
then, subject to the Employee's compliance with the provisions of paragraph 9
herein, and subject to paragraphs 8(e), (f), and (g) below, the Employee shall
be paid, as liquidated damages or severance pay, or both, and the Employee and
the dependents, beneficiaries, and estate of the Employee shall be provided
with, the following:
         (a)     The Employee shall be paid the excess of:
                 (i)      the fixed salary that would otherwise have been
                          provided in paragraph 4(a)(i) above, including the
                          increases therein provided, and any incentive
                          compensation and awards that would otherwise have
                          been payable under the provisions of any plan or
                          program in effect at such termination, calculated on
                          the assumption that any objectives for full payment
                          are obtained but not exceeded, less the amounts, if
                          any, the Employee would have paid in cash in respect
                          of employee benefits provided for in paragraphs
                          4(b)(iii) through (vii) above if the Employee were





                                      -10-

<PAGE>   133
                          still employed, over
                 (ii)     the amounts, if any, paid to the Employee pursuant to
                          any retirement, severance, separation or termination
                          pay program or arrangement of the Company or any of
                          its subsidiaries or affiliates.
                 Such payments shall commence with the month in which
                 termination shall have occurred, shall be made at the times
                 provided in paragraph 4(a) above, and shall continue for a
                 period of 12 months.

         (b)     The Employee shall also be paid the aggregate contributions or
                 payments, if any, that would have been made by the Company or
                 any of its subsidiaries or affiliates under the Thrift Plan
                 described in paragraph 4(b)(ii) above or any successor program
                 of the Company in effect on the date on which termination
                 shall have occurred, if the Employee had continued to be
                 employed, and to participate in the Thrift Plan or such
                 successor programs to the same extent as the Employee
                 participated for the last month during which the Employee was
                 permitted to participate, for a period of 12 months
                 thereafter, at an annual rate of compensation equal to that
                 used to calculate the payments provided by paragraph 8(a)
                 above.  Such payments shall be made at the times such
                 contributions would ordinarily have been made to the Thrift
                 Plan.

         (c)     For a period of 12 months (commencing with the month in which
                 termination shall have occurred), the Employee shall continue
                 to be entitled to all employee benefits provided for in
                 paragraphs 4(b)(iii) through (vii) above as if the Employee
                 were still employed during such period under this Agreement,
                 with benefits based upon the compensation used to calculate
                 the payments provided by paragraph 8(a) above, and if and to
                 the extent that such benefits shall not be payable or provided





                                      -11-

<PAGE>   134
                 under any such plan, the Company or any of its subsidiaries or
                 affiliates shall pay or provide such benefits on an individual
                 basis.  The benefits provided for in paragraph 4(b)(v) above
                 in accordance with this paragraph 8(c) shall be secondary to
                 any comparable benefits provided by another employer, provided
                 that an appropriate refund is made of any reduction in the
                 amount paid pursuant to paragraph 8(a)(i) which had assumed
                 that such benefits would be primary.

         (d)     The Employee and his beneficiary, if any, under the Retirement
                 Program described in paragraph 4(b)(i) above shall also be
                 paid the excess of: 
                 (i)      the aggregate benefit that would have been paid under 
                          the Retirement Program as in effect on the date first
                          above written, if the Employee had continued to be
                          employed and to be entitled to service credit for
                          eligibility and benefit purposes for a period of 12
                          months, at an annual rate of compensation equal to
                          that used to calculate the payments provided by
                          paragraph 8(a) above, calculated on the assumption
                          that the Employee is fully vested in such benefit,
                          over
                 (ii)     the aggregate benefit actually payable under the
                          Retirement Program and any successor retirement
                          program of the Company consisting of a tax-qualified
                          pension plan and a related excess benefit plan.
                 In clarification of the immediately preceding sentence, the
                 aggregate benefit that would have been paid under the
                 Retirement Program shall be calculated as of the normal or
                 early retirement date for which the Employee would have
                 qualified, if the Employee were still employed on that date,
                 and which would produce the highest benefit.  Such payments





                                      -12-

<PAGE>   135
                 shall commence on the date the Employee or his beneficiary, if
                 any, begins receiving payments under the Retirement Program,
                 shall be paid in the same form as under the Retirement Program
                 and shall continue until payments to the Employee and his
                 beneficiary, if any, cease under the Retirement Program.

         (e)     In the event that the Employee's Normal Retirement Date is
                 scheduled to occur during the 12-month period commencing with
                 the month in which the termination shall have occurred, the
                 payments and benefits provided for in paragraphs 8(a) through
                 (d) shall be based on the period commencing with such month
                 and ending with the month in which the Employee's Normal
                 Retirement Date occurs instead of said 12-month period,
                 regardless of whether the Company shall have extended the
                 Period of Employment beyond the Employee's Normal Retirement
                 Date pursuant to paragraph 3(a).

         (f)     In the event that the termination shall occur during the
                 12-month period commencing on the occurrence, if any, of a
                 Change in Control, the Employee shall be paid, no later than
                 15 days after the termination, a lump sum cash amount equal to
                 the present value of all amounts otherwise payable to the
                 Employee pursuant to paragraphs 8(a), (b) and (d) above,
                 determined by using a discount factor equal to the interest
                 rate that would have been used by the Pension Benefit Guaranty
                 Corporation for purposes of valuing immediate annuities under
                 a pension plan that terminated two months prior to the date on
                 which termination shall have occurred.

         (g)     To the extent that the Employee is entitled to receive cash
                 compensation that is (or would be, if any elective deferral
                 were disregarded) subject to Federal income taxation in
                 respect





                                      -13-

                 of other employment or a consulting position with another
                 company during the period upon which the payments and benefits
                 provided for in paragraphs 8(a) through (f) are based, the
                 payments to be made pursuant to such paragraphs shall be
                 correspondingly reduced, and, if necessary, the Employee shall
                 make an appropriate refund to the Company without interest.

         (h)     In the event the Employee's employment is terminated prior to
                 the expiration of this Agreement because of a disability, or
                 because of a Change of Control as defined in paragraph 7(c),
                 or because the Employee is terminated by the Company or any of
                 its subsidiaries or affiliates for a reason other than those
                 specified in paragraphs 7(a) or 7(b), the Employee shall be
                 entitled to (a) continue to participate in the Company's
                 medical and dental benefits programs in accordance with the
                 terms and conditions applicable to the Company's active and
                 retired employees, and (b) receive a special supplemental
                 payment from the Company in the amount of $3,333.33 a month,
                 beginning on the first day of the month following twelve full
                 calendar months after any such termination, and ending on the
                 last day of the month in which the Employee's death occurs or
                 the last day of the month in which the Employee attains age
                 55, whichever is the earlier.

9.  Disclosure of Information
The Employee recognizes and acknowledges that the trade secrets and other
confidential or proprietary information of the Company and its subsidiaries and
affiliates are valuable, special and unique assets of the business of the
Company and its subsidiaries and affiliates, access to and knowledge of which

The Employee will not, during or after the Period of Employment, in whole or in
part, disclose such secrets or information to any person, firm, corporation,





                                      -14-

association or other entity (except the authorized representatives of the
Company or any of its subsidiaries or affiliates) for any reason or purpose
whatsoever, nor shall the Employee make use of any such secrets or information
for his own purposes or for the benefit of any person, firm, corporation,
association or other entity (except the Company and its subsidiaries and
affiliates) under any circumstances, whether during or after the Period of
Employment, except as required by law, authorized in writing by order of the
Board of Directors of the Company or necessary in the ordinary course of the
Employee's duties under this Agreement, provided that, after the Period of
Employment, these restrictions shall not apply to such secrets or information
that are then in the public domain (provided that the Employee was not, in
breach in this paragraph 9, responsible, directly or indirectly, for such
secrets or information entering the public domain). In the event of a breach or
threatened breach by the Employee of this paragraph 9, the Company shall be
entitled to injunctive relief; provided, however, that nothing in this
paragraph 9 or in paragraph 8 shall abrogate or prohibit the Company from
pursuing any other remedies available to it for such breach or threatened
breach, including, but not limited to, the recovery of actual or punitive
damages or both.

10.  Source of Payments
All payments provided for in paragraphs 4, 5, 6, 8, and 11 herein shall be paid

                 Employee with respect to the subject matter of this Agreement
                 and the enforcement of rights hereunder, the Employee shall be
                 reimbursed for all reasonable costs and expenses relating to





                                      -15-

<PAGE>   138
                 such litigation or other proceeding, including his reasonable
                 attorneys' fees and expenses, provided that such litigation or
                 proceeding results in any:
                 (i)      settlement requiring the Company or any of its
                          subsidiaries or affiliates to make a payment to the
                          Employee; or
                 (ii)     judgment or order in favor of the Employee,
                          regardless of whether such judgment or order is
                          subsequently reversed on appeal or in a collateral
                          proceeding.

                 In no event shall the Employee be required to reimburse the
                 Company or any of its subsidiaries or affiliates for any of
                 the costs and expenses relating to such litigation or other
                 proceeding.  The obligation of the Company or any of its
                 subsidiaries or affiliates under this paragraph 11 shall
                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

         (b)     In the event of any dispute or difference between the Company
                 or any of its subsidiaries or affiliates and the Employee with
                 respect to the subject matter of this Agreement and the
                 enforcement of rights hereunder, other than a dispute arising
                 under paragraph 9 above, the Employee may, in his sole
                 discretion by notice to the Company or any such subsidiary or
                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the
                 Employee had notified the Company or any of its subsidiaries
                 or





                                      -16-

<PAGE>   139
                 affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be
                 selected by the American Arbitration Association (the "AAA")
                 in Philadelphia, Pennsylvania, upon the application of the
                 Employee.  The determination reached in such arbitration shall
                 be final and binding on both parties without any right of
                 appeal or further dispute.  Execution of the determination by
                 such arbitrator or arbitrators may be sought in any court of
                 competent jurisdiction.  The arbitrators shall not be bound by
                 judicial formalities and may abstain from following the strict
                 rule of evidence and shall interpret this Agreement as an
                 honorable engagement and not merely as a legal obligation.
                 Unless otherwise agreed by the parties, any such arbitration
                 shall take place in Wilmington, Delaware, and shall be
                 conducted in accordance with the rules of the AAA.

or affiliates from consolidating or merging into or with, or transferring all

<PAGE>   2
                 THIS AGREEMENT, made effective as of July 19, 1991, by and
between The Columbia Gas System, Inc. (the "Company"), a Delaware corporation,
and Logan W. Wallingford of Wilmington, Delaware (the "Employee"),

                         W I T N E S S E T H    T H A T


                 WHEREAS, the Board of Directors of the Company, at a meeting
held on July 19, 1991, determined that it would be in the best interests of the
Company and its shareholders to retain the services of certain key employees in
order to assure the continuity in the management of the Company's
administration and operations by entering into retention agreements with such
key employees for a period of three (3) years; and

                 WHEREAS, the Employee is a valuable employee of the Company
and an integral part of its management who participates in the decision-making
process relative to short and long term planning and policy for the Company;
and

                 WHEREAS, the Company wishes to assure itself of the continued
services of the Employee for the said period of three (3) years, by granting to
the Employee a Retention Award under certain conditions if he remains employed
by the Company at the end of said period of three (3) years;

                 NOW THEREFORE, it is hereby agreed by and between the parties
hereto as follows:

1.  RETENTION AWARD

         (a)     In the event the Employee's employment is not terminated prior
                 to July 19, 1994 by the Company or any of its subsidiaries or
                 affiliates for a reason specified in paragraph (b) below, and
                 provided further that the Employee remains employed by the
                 Company or any of its subsidiaries or affiliates on July 19,
                 1994, then the Employee shall be eligible to receive a
                 Retention Award of $95,445 on July 19, 1994.  In the event the
                 Employee's employment terminates prior to July 19, 1994
                 because of his death or disability, because of a Change of
                 Control as defined in paragraph (c) below, or because the
                 Employee is terminated by the Company or any of its
                 subsidiaries or affiliates for a reason other than those
                 specified in paragraph (b) below, then a pro-rata share of
                 said Retention Award shall be paid to the Employee or the
                 Employee's beneficiary.  Said pro-rata share of the Retention
                 Award shall be based on the date of termination in relation to
                 the three-year period of July 19, 1991 through July 19, 1994,
                 and shall be paid to the Employee or the Employee's
                 beneficiary as soon as practicable after the Employee's date
                 of termination.

         (b)     No portion of the Retention Award specified in paragraph 
<PAGE>   3

                 (a) above shall be paid to the Employee or the Employee's
                 beneficiary in the event the Employee's employment is
                 terminated by the Company or any of its subsidiaries or its
                 affiliates because of:

                 (i)      the Employee's serious, willful misconduct in respect
                          of the Employee's duties, including conviction for a
                          felony or perpetration of a common law fraud which
                          has resulted, or is likely to result, in material
                          economic damage to the Company or any of its
                          subsidiaries or affiliates; or

                 (ii)     the Employee's repeated failure to follow rules or
                          procedures of the Company or any of its subsidiaries
                          or affiliates, or to meetbona fide objectives and
                          qualifications duly promulgated as part of the
                          customary personnel practices of the Company or any
                          of its subsidiaries or affiliates.

         (c)     As used in this Agreement, "Change in Control" means the
                 happening of any of the following:

                 (i)      the acquisition by any party or parties of the
                          beneficial ownership of 25% or more of the voting
                          shares of the Company, or

                 (ii)     the occurrence of a transaction requiring
                          shareholders approval for the acquisition of the
                          Company through purchase or exchange of stock or
                          assets, or by merger, or otherwise, or

                (iii)     the election during a period of 24 months, or less,
                          of 30% or more, of the members of the Board of

                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be

                 honorable engagement and not merely as a legal obligation.

                                   ARTICLE IV
                   PARTNERSHIP FINANCING AND CAPITAL ACCOUNTS

  Section 4.01. Partners' Initial Capital Contributions. As of the date hereof,
CLG and COPE have contributed in cash to the capital of the Partnership the
amount set forth opposite their name on Appendix B hereto.  Such amount
constitutes the agreed value of such contribution made by such Partners.
  Section 4.02. Partnership Interests. In consideration of the Partners'
respective commitments to make Capital Contributions pursuant to this Article
IV, each Partner shall, as of the date hereof, have the Partnership Interest
set forth opposite such Partner's name on Appendix B hereto.
  Section 4.03. Initial Project Finance. Subject to satisfaction or waiver of
the applicable conditions precedent set forth in Article XVIII of this LP
Agreement:
  (a) Development Costs. On and as of the Construction Capital Closing Date,
the Columbia Partners' shall be deemed to have contributed to the Partnership,
and their Capital Accounts shall be ratably adjusted to reflect, all
expenditures made or incurred by them, or on behalf of them by any of their
Affiliates, prior to the Formation Date, up to $1 million in connection with
the planning, engineering, designing, financing, marketing of services, and
obtaining of FERC and other regulatory approvals for the Initial Project,
including without limitation, expenditures related to planning and development
of a proposed business plan for the Initial Project, as verified by COPE (the
"Qualified Development Expenditures").  The Columbia Partners shall neither
have any right of reimbursement with respect to such Qualified Development
Expenditures, nor shall such Qualified Development Expenditures be either (i)
included in the Columbia Partners' Cash Investment or (ii) considered for
purposes of Section 6.01(b).
  (b) CLG's Pre-Closing Initial Project Costs. After the Formation Date, costs
incurred by the Columbia Partners related to the development of the Initial
Project in accordance with the Approved Budget shall be treated as advances to
the Partnership.  On the Construction Capital Closing Date, the Columbia
Partners shall be reimbursed by the Partnership without interest, in cash, or
cash equivalents acceptable to the Columbia Partners, for all such costs
incurred by them between the Formation Date and the Construction Capital
Closing as verified by COPE, subject to a

LP Agreement                                                            
<PAGE>   7
maximum of $1 million.  To the extent that the Columbia Partners incur
additional costs related to the Initial Project above such $1 million amount
between the Formation Date and the Construction Capital Closing, then such
additional expenditures incurred in accordance with the Approved Budget for the
Initial Project and verified by COPE shall continue to be advances to the
Partnership by the Columbia Partners which shall be repaid without interest at
the Construction Capital Closing by crediting the amount of such additional
expenditures as a portion of the Columbia Partners' Cash Investment pursuant to
Section 4.03(e).
  (c) PEPCO Partners' Equity Capital. On the Construction Capital Closing Date,
the PEPCO Partners will contribute as a Capital Contribution to the
Partnership, in cash or cash equivalents acceptable to the General Partners,
$10 million, which amount shall be contributed by the PEPCO Partners in
proportion to their respective Partnership Interests and the PEPCO Partners'
respective Capital Accounts will be adjusted to reflect such Capital
Contribution.  The Partnership shall use such funds for the recommissioning of
the Facility and the implementation of the Initial Project, including, without
limitation, for construction of the Liquefaction Unit and related equipment,
for reimbursing CLG for its costs in accordance with the first sentence of
Section 4.03(b), for the Partnership's Property Taxes and O&M Expenses, and to
provide reasonable reserves for working capital requirements through the first
three (3) months after the In-Service Date, all in accordance with the Approved
Budgets and the Project Construction Plan for the Initial Project.  After the
proceeds of the PEPCO Partners' $10 million Capital Contribution (plus any
investment or reinvestment income earned thereon) have been depleted, the
Partnership shall make use of the Loan as needed to continue financing the
Initial Project.
  (d) The Loan. On and after the Construction Capital Closing Date, PENCO will
provide construction and term loans to the Partnership up to an aggregate
principal amount of $15 million (the "Loan") on a secured basis pursuant to,
and subject to the conditions precedent set forth in, the Loan Documents which
shall be satisfactory in form and substance to PENCO and the General Partners.
  (e) Columbia Partners' Equity Capital. If, and only after, the Loan proceeds
have been fully utilized as provided in the Loan Documents, any additional
amounts are necessary to fund the recommissioning, construction, Property
Taxes, O&M Expenses and working capital requirements through the In-Service
Date of the Initial Project, such additional amounts will be contributed in
cash, or cash equivalents acceptable to the General Partners, by the Columbia
Partners in proportion to their respective Partnership Interests, and the
Columbia's Partners' respective Capital Accounts will be adjusted to reflect
such Capital Contribution; provided, however, that such contributions shall be
required to be made only as and when required by the Partnership to fund such
recommissioning, construction, working capital, Property Taxes and O&M Expenses
in accordance with Approved Budgets; and provided,





            
                                      7
LP Agreement
<PAGE>   8
further, that the maximum obligation of the Columbia Partners to make such
Capital Contributions under this Section 4.03(e) shall be $7 million, less: any
amounts credited to the Columbia Partners' Cash Investment in accordance with
the last sentence of Section 4.03(b).  The Columbia Partners shall, on or prior
to the Construction Capital Closing, provide the Columbia Keepwell Letter to
the Partnership.
  (f) Cash Investment. For each Partner, the total of all Capital Contributions
made in the form of cash (or cash equivalents acceptable to the General
Partners) pursuant to Sections 4.03(c) or 4.03(e), as applicable, will
constitute such Partners' "Cash Investment" for purposes of making
distributions of Net Cash Flows pursuant to Article VI of this LP Agreement.
  (g) CLG's Contribution of the Facility. On the Construction Capital Closing
Date, CLG shall contribute the Facility and related assets to the Partnership,
and the Partnership shall assume certain obligations related to such assets,
all in accordance with the Asset Contribution Agreement.  The Columbia
Partners' Capital Accounts shall be adjusted to reflect the contribution of the
Facility at its Gross Asset Value as of the Construction Capital Closing Date,
as determined in accordance with Section 10.15(i) of this LP Agreement.
  Section 4.04. Additional Capital Contributions. After the In-Service Date of
the Initial Project, if the General Partners determine that the Partnership
requires additional Capital Contributions from the Partners for any purpose,
including the funding of any Additional Project in accordance with Section
17.03 of this LP Agreement, then the General Partners may cause Cash Calls for
such amounts to be given promptly to all Partners specifying the aggregate
Capital Contributions required and the amount of each Partner's ratable share
thereof.  Upon the date specified in any such Cash Call, which date shall not
be less than fifteen (15) days after the date such Cash Call is given, each
Partner shall contribute to the Partnership, in cash, its pro rata share, based
on its Partnership Interest set forth on Appendix B hereto, of the total amount
of additional capital required by the Partnership, provided, however, that no
Partner shall be required to make any additional Capital Contribution to the
Partnership other than such Capital Contributions as shall have been Consented
to by such Partner in advance of any such Cash Call, and provided, further,
that no Capital Contributions may be made by any Partner without the prior
approval of the General Partners.
  Section 4.05. Capital Accounts.
  (a) Maintenance of Capital Accounts. For each Partner, a separate capital
account (a "Capital Account") shall be established on the books and records of
the Partnership and maintained in accordance with Section 4.05(b) of this LP
Agreement.  In addition, to the extent necessary or appropriate under GAAP
and/or the accounting rules and regulations, if any, at the time prescribed by
the FERC or any other regulatory body or bodies with jurisdiction over the
Partnership or its assets, the Partnership shall maintain separate books and
records reflecting the Partners' capital in

LP Agreement                                                            
<PAGE>   9
accordance with such other accounting principles, provided, that, all
references in this LP Agreement to a Partner's Capital Account shall be to such
Partner's "Capital Account" as defined in the immediately preceding sentence.
The initial Capital Account established for any Transferee shall be in the same
amount as, and shall replace, the Capital Account of the Partner whom such
Transferee succeeds, and, for purposes of this LP Agreement, such Transferee
shall be deemed to have acquired the Partnership Interest of the Partner whom
such Transferee succeeds.  To the extent a Transferee acquires less than the
entire Partnership Interest of the Partner it succeeds, the original Capital
Account of such Transferee and its Partnership Interest shall be in proportion
to the interest it acquires, and the Capital Account of any Transferor Partner
who retains a partial interest in the Partnership, and the amount of its
Partnership Interest, shall be reduced in proportion to the interest it
retains.
  (b) Adjustments to Capital Accounts. The Capital Account of each Partner
shall be maintained and adjusted in accordance with the following provisions:
  (i) to such Partner's Capital Account there shall be credited such Partner's
  cash Capital Contributions and the Gross Asset Value of any non- cash Capital
  Contributions, such Partner's allocable share of Profits and any items in the
  nature of income or gain which are specially allocated pursuant to Section
  5.04 or Section 5.05 hereof, and the amount of any Partnership liabilities
  that are assumed by such Partner or that are secured by any Partnership
  assets distributed to such Partners;
  (ii) to such Partner's Capital Account there shall be debited the amount of
  cash and the Gross Asset Value of any Partnership assets distributed to such
  Partner pursuant to any provision of this LP Agreement, such allocable
  distributive share of Losses and any items in the nature of expenses or
  losses which are specially allocated pursuant to Section 5.04 or Section 5.05
  hereof, and the amount of any liabilities of such Partner that are assumed by
  the Partnership or that are secured by any property contributed by such
  Partner to the Partnership; and
  (iii) in determining the amount of any liability for purposes of this Section
  4.05(b), and for purposes of determining the amount of any Capital
  Contribution there shall be taken into account Section 752(c) of the Code and
  any other applicable provisions of the Code and Treasury Regulations.
  (c) The foregoing provisions and the other provisions of this LP Agreement
relating to the maintenance of Capital Accounts are intended to
comply with Treasury Regulations Section 1.704-1(b), and shall be interpreted
and applied in a manner consistent with such Treasury Regulations.  In the
event the General Partners shall determine that it is necessary or appropriate
to modify the manner in which the Capital Accounts, or any debits or credits
thereto (including, without limitation, debits or credits relating to
liabilities which are secured by contributed or distributed

property or which are assumed by the Partnership or any Partner), are computed
in order to comply with such Regulations, the General Partners may make such
modification, provided that it is not likely to have a material effect on the
amounts distributable to any Partner pursuant to Section 10.18 hereof upon the
dissolution of the Partnership.  The General Partners also shall (i) make any
adjustments that are necessary or appropriate to maintain equality between the
Capital Accounts of the Partners and the amount of Partnership capital
reflected on the Partnership's balance sheet, as computed for book purposes, in
accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(q), and (ii)
make any modifications that are necessary or appropriate in the event
unanticipated events might otherwise cause this LP Agreement not to comply with
Treasury Regulations Section 1.704- 1(b).
  Section 4.06. Status of Capital Contributions.
  (a) Return of Capital Contributions. No Partner shall be entitled to demand
or receive the return of any Capital Contribution, or to receive any funds or
property of the Partnership, except as otherwise expressly provided in this LP
Agreement, and no Partner shall be entitled to interest on any Capital
Contribution or the balance of its Capital Account.
  (b) No Partner Compensation. No Partner shall receive any interest, salary,
or drawing with respect to its Capital Contributions or its Capital Account or
for services rendered on behalf of the Partnership or otherwise in its capacity
as a Partner.  The foregoing shall not prohibit compensation to any Partner or
Affiliate of a Partner for services rendered to the Partnership (i) as
contemplated by the Operating Agreement, or (ii) to the extent approved in
writing by the General Partners.
  (c) Limited Liability. Except as otherwise specifically provided in the Act
or in this LP Agreement, no Limited Partner shall be liable for the debts,
liabilities, contracts or any other obligations of the Partnership.  Except as
otherwise specifically provided in the Act or in this LP Agreement, a Limited
Partner shall be liable only to make Capital Contributions as provided in
Article IV of this LP Agreement and, except as contemplated by Section 4.03(d),
shall not be required to lend any funds to the Partnership and, after such
Capital Contributions have been paid in accordance with this LP Agreement,
shall not be required to make any additional Capital Contributions to the
Partnership.  No General Partner shall have any personal liability for the
repayment of any loan, advance or Capital Contribution of any Limited Partner.
  (d) Defaulting Partners. Upon the failure of any Partner (a "Defaulting
Partner") to pay in full, or make provisions for payment reasonably acceptable
to the other Partners (the "Non-Defaulting Partners"), within ten (10) days
after Notice of default is received by such Partner (such tenth (10th) day
after delivery of such notice being the "Default Date"), any Capital
Contribution specified in any Cash Call or otherwise required to be made
pursuant to this LP Agreement (a "Defaulted Capital Contribution"):

<PAGE>   11
  (i) such Defaulting Partner shall not be entitled to exercise any voting or
  other consensual rights with respect to its Partnership Interest until such
  Defaulted Capital Contribution is cured, except as otherwise required by the
  Act or Section 13.02(b)(ii);
  (ii) the Non-Defaulting Partners shall have the right, but not the
  obligation, to make advances to the Partnership pursuant to Section 4.07 in
  an aggregate amount equal to the amount of such Defaulted Capital
  Contribution (a "Defaulted Contribution Advance") which shall be repaid
  (together with interest thereon at a rate per annum equal to the lesser of
  the then applicable Prime Rate or the maximum rate permitted by Applicable
  Law) prior to any distributions to Partners;
  (iii) the Defaulting Partner's distributions of Net Cash Flow and allocations
  to its Capital Account shall be suspended from the Default Date until such
  Defaulted Capital Contribution is cured in accordance with this Section
  4.06(d) whereupon, subject to Section 13.04(a), any suspended distributions
  shall be restored to the curing Partner;
  (iv) if such Defaulted Capital Contribution is not cured on or before the
  first anniversary of the Default Date, and the Defaulting Partner fails to
  cure (or provide for a cure reasonably acceptable to the Non-Defaulting
  Partners) within ten (10) days after a Notice of forfeiture is received by
  such Defaulting Partner (such tenth (10th) day after delivery of such Notice
  being the "Forfeiture Date"), the Defaulting Partner shall thereupon forfeit
  its Partnership Interest, and such Defaulting Partner shall have no rights or
  interest in the Partnership and shall cease to be a Partner;
  (v) if such Defaulted Capital Contribution is not cured in accordance with
  this Section 4.06(d), all amounts which would have been distributed to such
  Defaulting Partner from the Default Date to the Forfeiture Date shall be
  treated for all purposes of this LP Agreement as if distributed to such
  Defaulting Partner during such period and, subject to Section 13.04(a), such
  amounts shall be distributed to the remaining Partners in accordance with
  Section 6.01 and such Defaulting Partner's Capital Account shall be
  reallocated under Section 4.05(c) in accordance with the Partnership
  Interests of the remaining partners; and
  (vi) after the Forfeiture Date, the remaining General Partner(s) shall be
  entitled to cause the Partnership to commence any judicial or other
  proceeding with respect to damages resulting from a Defaulted Capital
  Contribution.
The provisions of this Section 4.06(d) shall constitute the Non-Defaulting
Partners' exclusive remedy with respect to such Defaulted Capital Contribution.
  Section 4.07. Advances. If any Partner shall advance any funds to the
Partnership in excess of its Capital Contribution, the amount of such advance
shall neither increase its Partnership Interest nor entitle it to any increase
in its share of the distributions of the Partnership.  The amount of any such
advance

shall be a debt obligation of the Partnership to such Partner and, except as
otherwise provided in (x) Section 4.06(d)(ii) with respect to advances relating
to Defaulted Capital Contributions or (y) Section 4.08 with respect to advances
relating to the Loan, shall be repaid to it by the Partnership with such
interest and upon such other terms and conditions as shall be agreed to in
writing by such Partner and the Partnership.  All Partner advances provided for
in this LP Agreement shall be payable and collectible only out of the
Partnership assets, and no Partner shall be personally obligated to repay any
part thereof.  No Person who makes any nonrecourse loan to the Partnership
shall have or acquire, as a result of making such loan, any direct or indirect
interest in the profits, capital, business or property of the Partnership,
other than as a secured creditor.  Except as provided in Section 4.06(d)(ii)
and Section 4.08, no Partner shall make any advances or loans to the
Partnership without the prior approval of the General Partners.
  Section 4.08. Advances Related to the Loan. (a) Unless prohibited by Section
6.02(a) of the Construction and Term Loan Agreement, before or after the
occurrence of any actual or threatened "Event of Default" as such term is used
in the Loan Documents, any Partner shall have the right, but not the
obligation, to advance funds to the Partnership as may be necessary under the
circumstances to avert or cure such Event of Default, as the case may be, or to
satisfy all or part of the Partnership's obligations under the Loan Documents
then due and owing (including, if such Event of Default gives rise to the
acceleration of the Loan, for payment of the outstanding principal amount of
the Loan, together with all accrued interest thereon and other costs then due
and owing in connection therewith).  The right of each Partner to make advances
pursuant to this Section 4.08 shall be ratable in accordance with its
Partnership Interest, provided, however, that in the event any Partner elects
not to advance its ratable share of such funds, the remaining Partners shall
have the right, but not the obligation, to advance additional funds to cover
any shortfall, which additional fund advances shall be made pro rata among the
advancing Partners determined on the basis of their Partnership Interests,
without giving effect to the Partnership Interest(s) of the non-advancing
Partner(s).
  (b) Upon the receipt by the Partnership of any Notice from the Lender as to
any Event of Default (or any notice of acceleration of the Loan), or in the
event that any Partner with knowledge of the occurrence or potential occurrence
of any Event of Default with respect to the Partnership's payment obligations,
gives Notice to one or more of the other Partners thereof, the Partners shall
have ten (10) days (or such shorter period as may be required under the
circumstances) to elect whether or not to make an advance contemplated by this
Section 4.08.  Any Partner's failure to make an election to advance during such
ten (10) day period shall be deemed such Partner's election not to exercise its
right to make an advance pursuant to this Section 4.08.  Any Partner may
condition its election on the receipt of necessary regulatory approvals by it

and its Affiliates.  Any Partner electing to make an advance pursuant to this
Section 4.08 shall promptly notify the Lender of its intent to do so.
  (c) Advances made pursuant to this Section 4.08 shall accrue interest at the
lesser of Two Hundred (200) basis points over the Prime Rate or the maximum
rate permitted by Applicable Law.  To the extent any advances made in
accordance with this Section 4.08 are made in partial payment of the Loan, the
Partnership's obligation to repay such advances shall be subordinate to the
Partnership's obligation to repay the Loan and, if requested by the Lender, the
advancing Partners shall execute subordination agreements reasonably
satisfactory to the Lender upon the making of any such advance.  The
Partnership shall repay any advances in accordance with this Section 4.08 in
such manner as shall be agreed to in writing by the General Partners, provided,
however, that in the event the General Partners are unable to agree on the
repayment terms of such advances:
  (i) The interest thereon shall be due and payable in arrears on the first day
  of each calendar quarter after the date of the advance (the "Advance Payment
  Date"); and
  (ii) the principal amount thereof shall be repaid in equal quarterly
  installments with the first installment due on the initial Advance Payment
  Date and the last installment due on the Advance Payment Date nearest in time
  to the stated maturity of the Loan;
provided, further, that all interest and principal due on such advance shall
automatically become due and payable in full upon the happening of any event
causing the dissolution of the Partnership pursuant to Section 13.02 hereof.

                                   ARTICLE V
                                  ALLOCATIONS

  Section 5.01. Annual Allocable Shares.
  (a) For any Fiscal Year with respect to which cash is distributed to the
Partners pursuant to Section 6.01 of this LP Agreement, each Partner's "Annual
Allocable Share" shall be a fraction equal to (x) the amount of cash
distributed to such Partner, divided by (y) the total amount of cash
distributed to all of the Partners for such Fiscal Year.
  (b) In all other Fiscal Years, each Partner's Annual Allocable Share shall be
determined in the same manner as provided in Section 5.01(a) using the fiction
that $1.00 of cash had been distributed to all of the Partners with respect to
such Fiscal Year in the proportions specified in Section 6.01(a) hereof.
  Section 5.02. Profits. (a) After giving effect to the special allocations set
forth in Sections 5.04 and 5.05 hereof, Profits for any Fiscal Year shall be
allocated among the Partners in proportion to their Annual Allocable Shares.
  (b) Notwithstanding Sections 5.02(a) and 5.03 hereof, Profits or Losses, if
any, attributable to a distribution (or to an event which produces a
distribution) under Section 6.02(c) hereof shall

be allocated among the Partners in accordance with each Partner's Partnership
Interest.
  Section 5.03. Losses.
  (a) After giving effect to the special allocations set forth in Sections 5.04
and 5.05 hereof, Losses for any Fiscal Year shall be allocated among the
Partners in proportion to their Annual Allocable Shares.
  (b) The Losses allocated pursuant to Section 5.03(a) hereof shall not exceed
the maximum amount of Losses that can be so allocated without causing any
Partner to have an Adjusted Capital Account Deficit at the end of any Fiscal
Year.  In the event some but not all of the Partners would have Adjusted
Capital Account Deficits as a consequence of an allocation of Losses pursuant
to Section 5.03(a) hereof, the limitation set forth in this Section 5.03(b)
shall be applied on a Partner by Partner basis so as to allocate the maximum
permissible Losses to each Partner under Section 1.704-1(b)(2)(ii)(d) of the
Treasury Regulations.  All Losses, if any, in excess of the limitations set
forth in this Section 5.03(b) shall be allocated to the General Partners in
proportion to their Partnership Interests.
  Section 5.04. Special Allocations. The following special allocations shall be
made in the following order:
  (a) Minimum Gain Chargeback. Except as otherwise provided in Section 
1.704-2(f) of the Treasury Regulations, notwithstanding any other provision of  
this Article V, if there is a net decrease in Partnership Minimum Gain during
any Fiscal Year, each Partner shall be specially allocated items of Partnership
income and gain for such Fiscal Year (and, if necessary, subsequent Fiscal
Years) in an amount equal to such Partner's share of the net decrease in
Partnership Minimum Gain, determined in accordance with Treasury Regulations
Section 1.704-2(g).  Allocations pursuant to the immediately preceding sentence
shall be made in proportion to the respective amounts required to be allocated
to each Partner pursuant thereto.  The items to be so allocated shall be
determined in accordance with Sections 1.704-2(f)(6) and 1.704-2(j)(2) of the
Treasury Regulations.  This Section 5.04(a) is intended to comply with the
minimum gain chargeback requirement in Section 1.704-2(f) of the Treasury
Regulations and shall be interpreted consistently therewith.
  (b) Partner Minimum Gain Chargeback. Except as otherwise provided in Section
1.704-2(i)(4) of the Treasury Regulations, notwithstanding any other provision
of this Article V, if there is a net decrease in Partner Nonrecourse Debt
Minimum Gain attributable to a Partner Nonrecourse Debt during any Fiscal Year,
each Partner who has a share of the Partner Nonrecourse Debt Minimum Gain
attributable to such Partner Nonrecourse Debt, determined in accordance with
Section 1.704-2(i)(5) of the Treasury Regulations, shall be specially allocated
items of Partnership income and gain for such Fiscal Year (and, if necessary,
subsequent Fiscal Years) in an amount equal to such Partner's share of the net
decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Partner
Nonrecourse Debt, determined in accordance with

Treasury Regulations Section 1.704-2(i)(4).  Allocations pursuant to the
immediately preceding sentence shall be made in proportion to the respective
amounts required to be allocated to each Partner pursuant thereto.  The items
to be so allocated shall be determined in accordance with Sections
1.704-2(i)(4) and 1.704-2(j)(2) of the Treasury Regulations.  This Section
5.04(b) is intended to comply with the minimum gain chargeback requirement in
Section 1.704-2(i)(4) of the Treasury Regulations and shall be interpreted
consistently therewith.
  (c) Qualified Income Offset. In the event any Limited Partner unexpectedly
receives any adjustments, allocations, or distributions described in Section
1.704-1(b)(2)(ii)(d)(4), Section 1.704-1(b)(2)(ii)(d)(5), or Section
1.704-1(b)(2)(ii)(d)(6) of the Treasury Regulations, items of Partnership
income and gain shall be specially allocated to each such Limited Partner in an
amount and manner sufficient to eliminate, to the extent required by the
Treasury Regulations, the Adjusted Capital Account Deficit of such Limited
Partner as quickly as possible, provided that an allocation pursuant to this
Section 5.04(c) shall be made only if and to the extent that such Limited
Partner would have an Adjusted Capital Account Deficit after all other
allocations provided for in this Section 5.04(c) have been tentatively made as
if this Section 5.04(c) were not in this LP Agreement.
  (d) Gross Income Allocation. In the event any Partner has a deficit in its
Capital Account balance at the end of any Fiscal Year which is in excess of the
sum of (i) the amount such Partner is obligated to restore pursuant to any
provision of this LP Agreement, and (ii) the amount such Partner is deemed to
be obligated to restore pursuant to the penultimate sentences of Sections
1.704-2(g)(1) and 1.704-2(i)(5) of the Treasury Regulations, each such Partner
shall be specially allocated items of Partnership income and gain in the amount
of such excess as quickly as possible, provided that an allocation pursuant to
this Section 5.04(d) shall be made only if and to the extent that such Partner
would have a deficit in its Capital Account balance in excess of such sum after
all other allocations provided for in this Article V have been made as if
Section 5.04(c) hereof and this Section 5.04(d) were not part of this LP
Agreement.
  (e) Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall
be specially allocated among the Partners in proportion to their Partnership
Interests.
  (f) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions for
any Fiscal Year shall be specially allocated to the Partner who bears the
economic risk of loss with respect to the Partner Nonrecourse Debt to which
such Partner Nonrecourse Deductions are attributable in accordance with
Treasury Regulations Section 1.704-2(i)(1).
  (g) Section 754 Adjustments. To the extent an adjustment to the adjusted tax
basis of any Partnership asset pursuant to Code Section 734(b) or Code Section
743(b) is required pursuant to Treasury Regulations Section
1.704-1(b)(2)(iv)(m)(2) or Treasury Regulations Section 1.704-
1(b)(2)(iv)(m)(4) to be taken into

account in determining Capital Account balances as the result of a distribution
to a Partner in complete liquidation of its Partnership Interest, the amount of
such adjustment to Capital Accounts shall be treated as an item of gain (if the
adjustment increases the basis of the asset) or loss (if the adjustment
decreases such basis) and such gain or loss shall be specially allocated to the
Partners in accordance with their interests in the Partnership in the event
Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Partner
to whom such distribution was made in the event Treasury Regulations Section
1.704-1(b)(2)(iv)(m)(4) applies.
  Section 5.05. Curative Allocations. The allocations set forth in Section 5.04
hereof (the "Regulatory Allocations") are intended to comply with certain
requirements of the Treasury Regulations.  It is the intent of the Partners
that, to the extent possible, all Regulatory Allocations shall be offset either
with other Regulatory Allocations or with special allocations of other items of
Partnership income, gain, loss, or deduction pursuant to this Section 5.05.
Therefore, notwithstanding any other provision of this Article V (other than
provisions relating to Regulatory Allocations), the General Partners shall make
such offsetting special allocations of Partnership income, gain, loss, or
deduction in whatever manner they determine appropriate so that, after such
offsetting allocations are made, each Partner's Capital Account balance is, to
the extent possible, equal to the Capital Account balance such Partner would
have had if the Regulatory Allocations were not part of this LP Agreement and
all Partnership items were allocated pursuant to Sections 5.02, 5.03, and 5.08
of this LP Agreement.  In exercising its discretion under this Section 5.05,
the General Partners shall take into account future Regulatory Allocations
under Sections 5.04(a) and (b) that, although not yet made, are likely to
offset other Regulatory Allocations previously made under Sections 5.04(e) and
(f).
  Section 5.06. Other Allocation Rules.
  (a) For purposes of determining the Profits, Losses, or any other items
allocable to any period, Profits, Losses, and any such other items shall be
determined on a daily, monthly, or other basis, as determined by the General
Partners using any permissible method under Code Section 706 and the Treasury
Regulations promulgated thereunder.
  (b) The Partners are aware of the income tax consequences of the allocations
made by this Article V and hereby agree to be bound by the provisions of this
Article V in reporting their shares of Partnership income and loss for income
tax purposes.
  (c) Solely for purposes of determining a Partner's proportionate share of the
"excess nonrecourse liabilities" of the Partnership within the meaning of
Section 1.752-3(a)(3) of the Treasury Regulations, the Partners' interests in
Partnership profits are in proportion to their Partnership Interests.
  (d) To the extent permitted by Section 1.704-2(h)(3) of the Treasury
Regulations, the General Partners shall endeavor to treat distributions of Net
Cash Flow as having been made from the




                                      16
LP Agreement                                                           
<PAGE>   17
proceeds of a nonrecourse liability or a Partner Nonrecourse Debt only to the
extent that such distributions would cause or increase an Adjusted Capital
Account Deficit for any Limited Partner.
  Section 5.07. Tax Allocations: Code Section 704(c). In accordance with Code
Section 704(c) and the Treasury Regulations thereunder, income, gain, loss, and
deduction with respect to any property contributed to the capital of the
Partnership shall, solely for tax purposes, be allocated among the Partners so
as to take account of any variation between the adjusted basis of such property
to the Partnership for federal income tax purposes and its initial Gross Asset
Value (computed in accordance with Section 10.15(i) hereof).  In the event the
Gross Asset Value of any Partnership asset is adjusted pursuant to Section
10.15(ii) hereof, subsequent allocations of income, gain, loss, and deduction
with respect to such asset shall take account of any variation between the
adjusted basis of such asset for federal income tax purposes and its Gross
Asset Value in the same manner as under Code Section 704(c) and the Treasury
Regulations thereunder.  Any elections or other decisions relating to such
allocations shall be made by the General Partners in any manner that reasonably
reflects the purpose and intention of this LP Agreement.  Allocations pursuant
to this Section 5.07 are solely for purposes of federal, state, and local taxes
and shall not affect, or in any way be taken into account in computing, any
Partner's Capital Account or share of Profits, Losses, other items, or
distributions pursuant to any provision of this LP Agreement.
  Section 5.08. Equalization Allocations in Connection with Liquidation
Distributions. Notwithstanding Sections 5.02 and 5.03 hereof, if and to the
extent that gain or loss is recognized, or deemed recognized pursuant to
Section 10.14(iii) hereof, in connection with the distribution to one or more
Partners of any assets of the Partnership or the sale of any assets of the
Partnership other than in the ordinary course of business, pursuant to Section
13.04 of this LP Agreement or otherwise, such gain or loss shall be allocated
among the Partners so that, to the maximum extent practicable the ratio of each
partner's Capital Account to the total of all Partners' Capital Accounts shall
be equal to each such Partner's Partnership Interest.

                                   ARTICLE VI
                                 DISTRIBUTIONS

  Section 6.01. Net Cash Flow. Except as otherwise specifically provided in
Article XIII (relating to the dissolution of the Partnership), any
distributions of the Net Cash Flow of the Partnership with respect to any
Fiscal Year shall be made to the Partners as follows:
  (a) Net Cash Flow Less Than Distribution Threshold. At the end of each Fiscal
Year, the Partnership's Net Cash Flow for such Fiscal Year shall be computed
(without regard to any Operator's Bonuses payable for such Fiscal Year) and, if
greater than zero, divided by the number which represents the cumulative total
of all




                                      17
LP Agreement                                                           
<PAGE>   18
the Partners' Cash Investments at that time.  If the resulting quotient is less
than .26 (the "Distribution Threshold"), then the Partnership's Net Cash Flow,
if any, for such Fiscal Year shall be distributed to the Partners, pro rata, in
the same proportion that each Partner's respective Cash Investment bears to the
combined total Cash Investments of all Partners.
  (b) Net Cash Flow Greater Than Distribution Threshold. At the end of each
Fiscal Year in which the quotient referred to in Section 6.01(a) equals or
exceeds the Distribution Threshold, the Net Cash Flow for such Fiscal Year
shall be distributed to the Partners in the following order:  (i) first, each
Partner will receive a cash distribution equal to 26% of its Cash Investment;
(ii) second, the Columbia Partners will receive a cash distribution equal to
26% of the difference between $25 million and the Columbia Partners' aggregate
Cash Investments, which shall be divided between them in shares proportionate
to their respective Partnership Interests; and (iii) third, any and all
remaining Net Cash Flow shall thereafter be distributed equally between the
Columbia Partners and the PEPCO Partners in shares proportionate to their
respective Partnership Interests.
  (c) Equalization. Beginning with the Fiscal Year following the first Fiscal
Year in which either (i) the Loan is fully repaid or (ii) the Partnership
commences the operation of a Terminalling Business, and continuing thereafter,
all Net Cash Flow, if any, shall be distributed equally between the Columbia
Partners and the PEPCO Partners in shares proportionate to their respective
Partnership Interests, without regard to the distribution mechanisms set forth
in Sections 6.01(a) and 6.01(b) (the "Equalization"), provided, however, that
in the event that the Loan is prepaid in full at any time during the five (5)
Fiscal Years following the Fiscal Year in which the In-Service Date of the
Initial Project occurs (the "In-Service Year"), Equalization shall take effect
commencing on the first day of the sixth (6th) Fiscal Year following the
In-Service Year.
  Section 6.02. Distribution Rules.
  (a) Net Cash Flow shall be distributed annually within sixty (60) days after
the close of each Fiscal Year unless otherwise approved by the General
Partners.
  (b) Any distributions of Net Cash Flow made by the Partnership pursuant to
Section 6.01 shall be made only in cash.  
  (c) All other distributions of cash to the Partners shall be distributed pro 
rata in accordance with each Partner's Partnership Interest at such times and
in such amounts as shall be determined by the General Partners in accordance
with this LP Agreement.
  Section 6.03. Restricted Distributions. Notwithstanding any provision to
contrary contained in this LP Agreement, the Partnership, and the General
Partners on behalf of the Partnership, shall not make a distribution to any
Partner on account of its Partnership Interest if such distribution would
violate Section 17-607 of the Act or other Applicable Law.

in such capacity on behalf of the Partnership, upon submission of receipts
therefor.

                                  ARTICLE VIII
                                   MANAGEMENT

business and affairs of the Partnership, to make all decisions affecting the
business and affairs of the Partnership and to take all such actions as they

  laws of the United States, the securities rules and regulations of any State
  of the United States, the laws of any other jurisdiction, the rules and

provided, however, that the expression of any power or authority of the General
Partners in this LP Agreement shall not in any way limit or exclude any other
power or authority which is not specifically or expressly set forth in this LP
Agreement, and provided, further, that the Partnership shall at all times be

<PAGE>   22
  (v) except in accordance with the express terms hereof, admit a Person as an
  additional, successor or substituted Partner of the Partnership.
  (c) Manner of Taking Action. All powers vested in the General Partners
pursuant to this LP Agreement shall be exercised only with the unanimous
Consent of all General Partners and all agreements or other documents executed
on behalf of the Partnership shall be executed by each and every General
Partner, provided, however, that the General Partners may, and it is the intent
of the Parties hereto that the General Partners shall whenever practicable, act
through their designated Representatives in the manner provided for in Section
8.09 of this LP Agreement.
  Section 8.03. Outside Businesses. The General Partners shall engage in no
business activities other than in connection with their acting as General
Partners hereunder.  The Limited Partners and their respective officers,
directors, stockholders, employees, agents and Affiliates (other than the
General Partners) may engage in or possess an interest in other business
ventures of any nature or description, independently or with others, similar or
dissimilar to the business of the Partnership, and neither the Partnership nor
any other Person shall have any rights by virtue of this LP Agreement in and to
such independent ventures or the income or profits derived therefrom, and the
pursuit of any such venture, even if competitive with the business of the
Partnership, shall not be deemed wrongful or improper.  None of the Partners or
their respective officers, directors, stockholders, employees, agents and
Affiliates shall be obligated to present any particular investment opportunity
to the Partnership even if such opportunity is of a character which, if
presented to the Partnership, could be taken by the Partnership, and any such
Person shall have the right to recommend to others any such particular
investment opportunity or, in the case of any such Person other than a General
Partner, to take for its own account (individually or as a partner or
fiduciary) any such particular investment opportunity.
  Section 8.04. Relationships with Affiliates. The Partnership may enter into
any agreement or contract with any Partner, any Person who is an Affiliate of a
Partner, or any of their respective officers, directors, stockholders,
employees and agents, to the extent approved by the General Partners, provided
that any such agreement or contract shall contain substantially such terms and
conditions as would be contained in a similar agreement or contract entered
into by the Partnership as the result of arm's-length negotiations from a
comparable unaffiliated disinterested third party.  The Transaction Documents
shall be deemed to be in compliance with this Section 8.04.  The Partners agree
that (i) CLNG Corp. shall have sole authority, as General Partner, to act on
behalf of the Partnership with respect to any purported breach under the Loan
Documents, and (ii) COPE shall have sole authority, as General Partner, to act
on behalf of the Partnership with respect to any purported breach under the
Operating Agreement.  In the event of any conflict between the Partnership and
any such affiliated Person, the General Partners shall resolve such conflict




                                      22
LP Agreement                                                           
<PAGE>   23
in accordance with Section 8.07 of this LP Agreement, provided, that any
General Partner may, in its sole discretion, recuse itself from taking any
action contrary to its or its Affiliates' interests with respect to such
conflict, by written Notice to the other General Partner(s), upon which such
other General Partner(s) shall have sole power and authority to resolve such
conflict in the manner provided in Section 8.07.
  Section 8.05. Title to Assets of the Partnership. Title to assets of the
Partnership, whether real, personal or mixed, tangible or intangible, shall be
deemed to be owned by the Partnership as an entity, and no Partner,
individually or collectively, shall have any ownership interest in such assets
of the Partnership or any portion thereof.  Title to any or all of the assets
of the Partnership may be held in the name of the Partnership, any General
Partner or in the name of one or more nominees, as the General Partners may
determine.  Each General Partner hereby declares and warrants that any assets
of the Partnership for which legal title is held in the name of such General
Partner shall be held in trust by the General Partner for the use and benefit
of the Partnership in accordance with the terms and provisions of this LP
Agreement.  All assets of the Partnership shall be recorded as the property of
the Partnership on its books and records, irrespective of the name in which
legal title to such assets of the Partnership is held.
  Section 8.06. Non-Recourse. Unless otherwise approved by the General
Partners, the Partnership shall not enter into any contract, lease, sublease,
note, deed of trust, or other agreement or contractual obligation, unless there
is contained therein an appropriate provision limiting the claims of all
Parties to such instrument and other beneficiaries thereunder to the assets of
the Partnership and expressly waiving any rights of such Parties and other
beneficiaries to proceed against any of the Partners individually; provided,
however, the Partnership may enter into contracts not containing such a
provision provided that such contract is in the ordinary course of its business
and the Partnership's obligations thereunder (including any potential or
contingent obligations for any purported breach of any such contract) are in
the aggregate less than $25,000.
  Section 8.07. Resolution of Conflicts of Interest.
  (a) Manner of Resolution. Except as expressly provided in the third sentence
of Section 8.04, and subject to the right of recusal set forth in the proviso
in Section 8.04, (i) whenever a conflict of interest exists or arises between
any General Partner or any of its Affiliates, on the one hand, and the
Partnership, or any other Partner on the other hand, or (ii) whenever this LP
Agreement or any other agreement contemplated herein or therein provides that
the General Partners shall act in a manner which is, or provides terms which
are, fair and reasonable to the Partnership, or any Limited Partner, the
General Partners shall resolve such conflict of interest in, or otherwise act
in a manner consistent with, the best interests of the Partnership, provided,
that in taking such action or providing such terms, the General Partners may
consider

LP Agreement                                                           
<PAGE>   24
in each case the relative interests of each Party to such conflict, agreement,
transaction or situation and the benefits and burdens relating to such
interests, any customary or accepted industry practices, and any applicable
generally accepted accounting practices or principles.  In the absence of bad
faith, the resolution, action or terms so made, taken or provided by any
General Partner in accordance with this Section 8.07(a) shall not constitute a
breach of this LP Agreement or any other agreement contemplated herein or of
any duty or obligation of the General Partner at law or in equity or otherwise.
  (b) Meaning of Discretion. Whenever in this LP Agreement the General Partners
are permitted or required to make a decision (i) in their "sole discretion" or
"discretion" or under a grant of similar authority or latitude, the General
Partners shall be entitled to consider only such interests and factors as they
desire, provided, however, that in all cases the General Partners shall
consider, and act in accordance with, the best interests of the Partnership or
(ii) in "good faith" or under another expressed standard, the General Partners
shall act under such express standard and shall not be subject to any other or
different standards imposed by this LP Agreement or any other agreement
contemplated herein or by Applicable Law or in equity or otherwise.
  (c) Arbitration. In the event the General Partners are unable to agree as to
the resolution of any conflict, and no General Partner has sole authority to
act on behalf of the Partnership with respect to such issue pursuant to Section
8.04, the issue shall be resolved by arbitration in accordance with Article XIV
of this LP Agreement.
  (d) No Liability. No General Partner shall be liable to the Partnership or to
any other Partner for acting in accordance with the good faith belief and

  Section 8.08. Merger. The Partnership may merge with, or consolidate into,
another business entity (as defined in Section 17-211(a) of the Act) upon the
approval by the General Partners and a Majority Vote.  In accordance with
Section 17-211 of the Act (including Section 17- 211(g)), notwithstanding
anything to the contrary contained in this LP Agreement, an agreement of merger
or consolidation approved by the General Partners and a Majority Vote, may (A)
effect any amendment to this LP Agreement, or (B) effect the adoption of a new
partnership agreement for the Partnership if it is the surviving or resulting
limited partnership of the merger or consolidation.  Any amendment to this LP
Agreement or adoption of a new partnership agreement made pursuant to the
foregoing sentence shall be effective at the effective time or date of the
merger or consolidation.  For purposes of any vote required by the Limited
Partners in connection with any merger or consolidation, the Limited Partners

permitted by law.
  Section 8.09. Partnership Governance.
  (a) Appointment of Representatives/Partnership Officials. Upon the execution
of this LP Agreement, each of the General Partners shall appoint one (1)
individual to represent and vote for such General Partner with respect to any
matter within the powers of the General Partners hereunder (the
"Representatives").  Each General Partner shall also appoint one or more
individuals to be such General Partner's "Alternate Representatives" with full
power of substitution and authority to act in place of individuals to be such
General Partner's Representative in the event of the unavailability of such
Representative.  Each Representative and Alternate Representative shall be
deemed to be acting solely in a representative capacity on behalf of the
General Partner that he or she represents, and in so doing, to the maximum
extent permitted by Applicable Law, shall have no fiduciary duty (including,
without limitation, any duty of loyalty, candor or care) to any Person other
than to such General Partner, provided, that the foregoing shall not diminish
or affect any such duty owed by the General Partner to the Partnership.  Each
General Partner shall have only one vote at any meeting of the General Partners
exercisable through its Representative or Alternate Representative, as the case
may be.  As of the date hereof, each General Partner's Representative and
Alternate Representatives are those listed on Appendix C hereto.  Each General
Partner reserves the right to change any one or more of its Representatives or
Alternate Representatives, as the case may be, and to appoint successors and
substitutes therefor, from time to time, in such General Partner's sole
discretion, and any such change shall be effective upon such General Partner
delivering a Notice of such change to the other General Partner.  Except as may
be specifically provided otherwise herein, or in any written directives that
are executed by all of the General Partners, all approvals, decisions and
actions with respect to the management and control of the Partnership that have
been made or taken by the Representatives or Alternate Representatives, as the
case may be, in accordance with this Section 8.09, shall be approvals,
decisions and actions duly made or taken by the General Partners hereunder, and
as such shall be binding on the Partnership and the Partners.  Each General
Partner shall have the right to call meetings on three (3) business days'
Notice to the other General Partner.  Meetings of the General Partners shall be
held at the offices of the Partnership at Cove Point, Maryland, unless
otherwise agreed to by the General Partners.
  (b) Rules and Regulations. From time to time, the General Partners may adopt
rules and regulations consistent with this LP Agreement with respect to the
operation and governance of the Partnership (the "Rules and Regulations").  The
Rules and Regulations may, among other things, govern the conduct of meetings
of the General Partners, and describe the duties of Partnership Officials.
Neither the adoption of any Rules and Regulations in accordance with this
Section 8.09(b) nor the adoption of any




                                      25
LP Agreement

amendment or supplement to such Rules and Regulations, shall be deemed an
amendment to this LP Agreement.  Any reference in this LP Agreement to the
Rules and Regulations shall be deemed to be a reference to the same as amended
or supplemented and in effect from time to time.
  (c) Partnership Officials. Unless otherwise approved by the General Partners,
there shall at all times be appointed a Chairman and Vice Chairman of the
Partnership.  The General Partners shall elect the first Chairman and the first
Vice Chairman of the Partnership at an organizational meeting of the General

occurring after the In-Service Date for the Initial Project or (ii) January 1,
1996, and continuing annually thereafter, nomination of the Chairmanship and
Vice Chairmanship shall rotate among the General Partners, and elections will
take place no later than ten (10) business days after the close of the
Partnership's Fiscal Year, or such later date as fixed by approval of the
General Partners.
  (d) The Chairman and Vice Chairman. Unless otherwise approved by the General
Partners, the Chairman shall at all times be a duly appointed Representative,
and shall preside at all meetings of the General Partners.  The Vice Chairman
shall also be a Representative and shall perform the duties of the Chairman at
the request, or in the absence, of the Chairman, or upon the refusal or
inability of the Chairman to perform his or her responsibilities.  The Chairman
and Vice Chairman shall have the power and authority to execute on behalf of
the Partnership, and obligate the Partnership to perform, any contracts,
agreements and other documents or instruments specifically approved by the
General Partners for execution by the Chairman, Vice Chairman or both, as the
case may be, provided, however, that such approval shall not limit the power of
the General Partners to execute on behalf of the Partnership, and cause the
Partnership to perform, any contracts, agreements and other documents of the
Partnership, to the extent execution by the General Partners is necessary or
appropriate under the circumstances.
  (e) Other Officers. The General Partners may, from time to time, appoint such
other Partnership Officials as the General Partners deem necessary or
appropriate, including, without limitation, a Secretary and a Controller for
the Partnership and any assistants thereto.  Such Partnership Officials shall
serve at all times under the supervision of, and at the pleasure of the General
Partners, and their functions and duties shall be only as prescribed by the
General Partners by written directive.

by the Operator to the extent provided in the Operating Agreement, or by any
director, officer, or employee of the Operator.
  (g) Indemnification by General Partner. To the fullest extent permitted by
Applicable Law, each General Partner shall indemnify and hold harmless those
Representatives, Alternate Representatives, Partnership Officials (or other
individuals acting in connection with the Partnership's business or affairs at
the request of such General Partner) who are its employees or employees of its
Affiliates, against all actions, claims, demands, costs (including fees and
expenses of counsel) and liabilities arising out of the acts (or failure to
act) of any such Persons based upon any actual or alleged breach of fiduciary
duty (including any duty of care, candor or loyalty) owed or claimed to be
owed, to the Partnership.
  Section 8.10. The Operator. The Partnership shall retain the Operator to
provide certain services as an independent contractor under the Operating
Agreement.  The Operator shall have no duties or obligations to the Partnership
or the Partners other than the duties and obligations of the Operator expressly
set forth in the Operating Agreement.
  Section 8.11. Request for Instructions. In the event that any Partnership
Official is unsure of the application of any provision of this LP Agreement,
any related Transaction Document or any other agreement relating to the
transactions contemplated hereby or thereby, such Partnership Official may
request and rely upon written instructions of the General Partners (which
instructions shall be signed by an authorized officer of each General Partner);
provided, however, that if such instructions have not been received within
twenty (20) days after the date of such request (or such earlier date as
reasonably requested or as necessary under the circumstances) until instructed
otherwise, the requesting Person may, but shall be under no duty to, take or
refrain from taking such action as the requesting Person may deem advisable in
the best interests of the Partnership.

                                LIMITED PARTNERS

  Section 9.01. Liability of Limited Partners. Except as otherwise expressly
required by law, a Limited Partner, in its capacity as such, shall have no
liability in excess of (i) the amount of its Capital Contributions, (ii) its
share of any undistributed profits and assets of the Partnership, (iii) its
obligation to make other payments expressly provided for in this LP Agreement,
and (iv) the amount of any distributions wrongfully distributed to it.  It is
the intent of the Parties hereto that no distribution to any Limited Partner
shall be deemed a return of any money or other property in violation of the
Act.  The payment of any such money or distribution of any such property to a
Limited Partner shall be deemed to be a compromise within the meaning of
Section 17-502(b) of the Act, and the Limited Partner receiving any such money
or property shall not be required to return any such money or property to any
Person, the Partnership or any creditor of

the Partnership.  However, if any court of competent jurisdiction finally
determines that, notwithstanding the provisions of this LP Agreement, any
Limited Partner is obligated to return such money or property, such obligation
shall be the obligation of such Limited Partner and not of the General
Partners.
  Section 9.02. No Management by Limited Partners. No Limited Partner, in its
capacity as such, shall have any right to be represented at any meeting of the
General Partners or otherwise to take part in the management, operation or
control of the business and affairs at the Partnership.  The Limited Partners
shall not have any right, power, or authority to transact any business in the
name of the Partnership or to act for or on behalf of or to bind the
Partnership.  A Limited Partner shall have no rights other than those
specifically provided herein or granted by Applicable Law.
  Section 9.03. Employees, Agents or Officers of the Partnership or a General
Partner. An employee, agent, director or officer of a Limited Partner may also
serve as a Partnership Official or be an employee, agent, director or officer
of the Operator or any General Partner.  The existence of these relationships
and acting in such capacities will not result in a Limited Partner being deemed
to be participating in the control of the business of the Partnership or
otherwise affect the liability of the Limited Partner or the Person so acting.

inspection and examination at reasonable times by all Limited Partners and
their duly authorized representatives for any purpose reasonably related to
such Limited Partner's interest as a Limited Partner in the Partnership.

of each Fiscal Year of the Partnership by a firm of independent certified
public accountants of national reputation selected by the General Partners.
  Section 10.02. [RESERVED]

  quarter, as the case may be, such financial statements referred to in clauses
  (i), (ii) and (iii) of Section 10.03(a)(1) on an unaudited basis.  Such

  subject to normal year-end adjustments and the absence of notes, and shall be
  accompanied by a certification by the General Partners that such financial
  statements present fairly in all material respects the financial condition
  and results of operations of the Partnership for the periods indicated.

be deposited in the Partnership's name in such bank or brokerage account or
accounts as shall be designated by the General Partners.  Withdrawals from any
such bank or brokerage account or accounts shall be made upon such signature or
signatures as the General Partners may designate.  Such funds shall not be
commingled with the funds of any other Person.  Subject to prior approval by
the General Partners, the Partnership may make such short-term investments of

that would require registration of the Partnership under the Investment Company
Act of 1940 or would otherwise be prohibited by Applicable Law.
  Section 10.05. Right to Make Section 754 Election. The General Partners may,
in their sole discretion, make or revoke, on behalf of the Partnership, an
election in accordance with Section  754 of the Code, so as to adjust the basis
of Partnership property in the case of a distribution of property within the
meaning of Section  734 of the Code, and in the case of a Transfer of a
Partnership interest within the meaning of Section  743 of the Code.  Each of
the Partners shall, upon request of the General Partners, supply the
information necessary to give effect to such an election.

  (a) Designation. CLNG Corp. is hereby designated as the initial "Tax Matters
Partner" (the "TMP"), of the Partnership as defined in Section 6231(a)(7) of

on the TMP's discretion set forth in Section 10.06(d)) to manage and control,
on behalf of the Partnership, any administrative proceeding at the Partnership
level with the IRS relating to the determination of any item of




                                      30

<PAGE>   31
Partnership income, gain, loss, deduction or credit for federal income tax
purposes. The TMP and other Partners shall use their best efforts to comply
with the responsibilities (including, without limitation, the making of
elections and preparing of returns) outlined in this Article X and in Sections
6622 through 6231 and 6050K of the Code and in doing so shall incur no
liability to any other Partner, provided, that such efforts are undertaken in
good faith and in a manner that the TMP or Partner, as the case may be,
believes to be in the best interests of the Partners generally.     
  (b) IRS Notices. The TMP shall, within ten (10) days after the TMP's
receipt of any notice from the IRS in any administrative proceeding at the
Partnership level relating to the determination of any Partnership item of
income, gain, loss, deduction or credit, mail a copy of such notice to each
Partner.
  (c) New Tax Matters Partners. The Partners may at any time hereafter
designate a new TMP; provided, however, that only a General Partner may be
designated as the TMP of the Partnership and the Partner serving as TMP for a
given taxable year shall continue as TMP with respect to all matters concerning
such year.
  (d) No Discretion. Unless otherwise expressly provided in this LP Agreement,
or required by the Code or Treasury Regulations, the TMP shall act (or refrain
from acting) on behalf of the Partnership in accordance with the directions of
the General Partners, and shall make no election, declaration or statement,
settle or compromise any audit matter or dispute, or execute or file any tax
return, tax filing or other document on behalf of the Partnership without the
prior approval of the General Partners.
  Section 10.07. Partnership Status. It is the intention of the Partners that
the Partnership be treated as a partnership for purposes of federal and state
income tax, and each Partner hereby covenants that it will make no election,
declaration or statement on or in any tax return, tax filing, or any book or
record maintained by it which is inconsistent with or detrimental to the
Partnership's ongoing maintenance of partnership tax status.
  Section 10.08. Income Tax Compliance and Capital Accounts. The TMP shall
prepare or cause to be prepared and filed on behalf of the Partnership, when
and as required by Applicable Law, all federal, state and local income tax
information returns or requests for extensions thereof.  Not less than two
weeks prior to the due date (including extensions) for any return, the TMP
shall submit to each Partner a copy of the return as proposed for review and a
schedule showing the Partner's allocable share of partnership tax attributes
("Tax Attributes") sufficient to allow such Partner to include such Tax
Attributes in its federal income tax return. Each Partner shall provide to the
TMP, when and as requested, all information concerning the affairs of such
Partner as may be reasonably required to permit the filing of such returns.
  Section 10.09. Tax Elections. The TMP shall make the following tax elections
on behalf of the Partnership:
  (a) Unless required to adopt a different taxable year pursuant to Section 
706(b) of the Code, adopt the calendar year as the annual accounting period;




                                      31
LP Agreement                                                           
<PAGE>   32
  (b) Adopt the accrual method of accounting;
  (c) Deduct interest expense and taxes attributable to the construction or
installation of real and personal property improvements to the fullest extent
permitted by the Code;
  (d) Compute the allowance for depreciation under the most accelerated tax
depreciation method and using the shortest life and lowest salvage value
authorized by Applicable Law, consistent with the election provided for in
Section 10.09(e), with respect to all depreciable assets;
  (e) If allowed by the Code, and to the maximum extent allowable, elect to
take available investment tax credit on the full basis of each asset.
  (f) Make the election provided for in Section 754 of the Code if, and only
if, each Partner who has acquired a Partnership Interest with respect to which
the election is made or is in effect shall have provided to the TMP
concurrently, or within thirty (30) days after the end of the tax year in which
such Partnership Interest is acquired, its irrevocable and unconditional
written undertaking to the effect that it, and its successors in interest
hereunder, will reimburse the Partnership annually for additional
administrative costs reasonably incurred by the Partnership as a result of such
election as determined by the Partnership's Certified Public Accountants; and
  (g) Make such other elections as the TMP shall have been directed in writing
by the General Partners to make.  The requirement to make any of the elections
set forth in Sections 10.09(a) through 10.09(f) is predicated upon the
assumption that current federal income tax law will continue in force. If any
legislative change is made in the Code or any other tax statutes or by the IRS
in regulations and other pronouncements or by the courts in case law affecting
any of such elections so as to materially alter the economic result of the
required election, the TMP shall make such election in respect of the item so
affected as directed by the General Partners; provided, however, that such
election shall be made in a manner consistent with the best interests of the
Partners as a group.
  Section 10.10. Allocation of Tax Attributes. Subject to the provisions of
Sections 10.11 and 10.14, and Article XIII, the Profits and Losses, as the case
may be, of the Partnership for each Fiscal Year and, in each case, all related
tax characteristics or attributes of the Partnership, or tax credits of the
Partnership, shall be allocated among the Partners in accordance with the
provisions of Article V.
  Section 10.11. Specific Tax Allocation Rules. It is the intention of the
Partners that the allocation of Tax Attributes arising from the Partnership
comply with applicable provisions of the Code and  Treasury Regulations Section
1.704-1(b) as they exist and any amendments thereto.  Notwithstanding anything
to the contrary in this Section 10.11, each General Partner shall at all times
be allocated at least 1% of each item of Partnership Tax Attributes.

written notice specifying such change.

each Fiscal Year, an amount equal to the Partnership's taxable income or loss,
as the case may be, for such Fiscal Year, determined in accordance with Section
703(a) of the Code (but including in taxable income or loss, for this purpose,
all items of income, gain, loss or deduction required to be stated separately
pursuant to Section  703(a)(1) of the Code), with the following adjustments:
  (i) any income of the Partnership exempt from federal income tax and not
  otherwise taken into account in computing Profits or Losses pursuant to this
  definition shall be added to such taxable income or loss;
  (ii) any expenditures of the Partnership described in Section  705 (a)(2)(B)
  of the Code (or treated as expenditures described in Section 705(a)(2)(B) of
  the Code pursuant to Treasury Regulation Section  1.704-1(b)(2)(iv)(i)) and
  not otherwise taken into account in computing Profits or Losses pursuant to
  this definition shall be subtracted from such taxable income or loss;
  (iii) in the event the Gross Asset Value of any Partnership asset is adjusted
  in accordance with Paragraph (ii) or Paragraph (iii) of the definition of
  "Gross Asset Value" in Section 10.15, the amount of such adjustment shall be
  taken into account as gain or loss from the disposition of such asset for
  purposes of computing Profits or Losses;
  (iv) gain or loss resulting from any disposition of any asset of the
  Partnership with respect to which gain or loss is recognized for federal
  income tax purposes shall be computed by reference to the Gross Asset Value
  of the asset disposed of, notwithstanding that the adjusted tax basis of such
  asset differs from its Gross Asset Value;
  (v) in lieu of the depreciation, amortization and other cost recovery
  deductions taken into account in computing such taxable income or loss, there
  shall be taken into account Depreciation for such Fiscal Year or other
  period, computed in accordance with the definition of "Depreciation" in
  Appendix A hereto;
  (vi) to the extent an adjustment to the adjusted tax basis of any Partnership
  asset pursuant to Code Section 734(b) or Code Section 743(b) is required
  pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) to be taken
  into account in determining Capital Accounts as a result of a distribution
  other than in liquidation of a Partner's Interest, the amount of such
  adjustment shall be treated as an item of gain (if the adjustment increases
  the basis of the asset) or loss (if the adjustment decreases the basis of the
  asset) from the

  disposition of the asset and shall be taken into account for purposes of
  computing Profits or Losses; and (vii) notwithstanding any other provision of
  this Section 10.14, any items which are specially allocated pursuant to
  Section 5.04 or Section 5.05 hereof shall not be taken into account in
  computing Profits or Losses.  The amounts of the items of Partnership income,
  gain, loss, or deduction available to be specially allocated pursuant to
  Sections 5.04 and 5.05 hereof shall be determined by applying the rules set
  forth in Sections 10.14(i) through 10.14(vi) above, as applicable.
  Section 10.15. Gross Asset Value. "Gross Asset Value" means, with respect to
any asset, such asset's adjusted basis for federal income tax purposes, except
as follows:
  (i) the initial Gross Asset Value of any asset contributed by a Partner to
  the Partnership shall be the gross fair market value of such asset as agreed
  to by the contributing Partner and the other Partners; provided that, the
  initial Gross Asset Value of the Facility and related assets contributed to
  the Partnership pursuant to Section 4.03(g) hereof shall be equal to CLG's
  tax basis thereof as of the Construction Capital Closing Date (it being
  acknowledged and agreed by the Partners that, as of July 1, 1994, CLG's tax
  basis in such assets is estimated to be $5.2 million);
  (ii) the Gross Asset Value of all Partnership assets shall be adjusted to
  equal their respective gross fair market values, as determined by the General
  Partners, as of the following times: (a) the acquisition of an additional
  interest in the Partnership by any new or existing Partner in exchange for
  more than a de minimis Capital Contribution; (b) the distribution by the
  Partnership to a Partner of more than a de minimis amount of Partnership
  assets as consideration for an interest in the Partnership; and (c) the
  liquidation of the Partnership within the meaning of Treasury Regulation
  Section  1.704-1(b)(2)(ii)(g); provided, however, that adjustments pursuant
  to Clause (a) and Clause (b) of this sentence shall be made only if the
  General Partners reasonably determine that such adjustments are necessary or
  appropriate to reflect the relative economic interests of the Partners in the
  Partnership;
  (iii) the Gross Asset Value of any Partnership asset distributed to any
  Partner shall be the gross fair market value of such asset on the date of
  distribution, as determined by the distributee Partner and the General
  Partners;
  (iv) the Gross Asset Values of Partnership assets shall be increased (or
  decreased) to reflect any adjustments to the adjusted basis of such assets
  pursuant to Code Section 734(b) or Code Section 743(b), but only to the
  extent that such adjustments are taken into account in determining Capital
  Accounts pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m) and
  Sections 10.14(vi) and 5.04(g) hereof; provided, however, that Gross Asset
  Values shall not be

  adjusted pursuant to this paragraph (iv) to the extent the General Partners
  determine that an adjustment pursuant to paragraph (ii) above is necessary or
  appropriate in connection with a transaction that would otherwise result in
  an adjustment pursuant to this paragraph (iv); and
  (v) if the Gross Asset Value of an asset has been determined or adjusted
  pursuant to Paragraphs (i),   (ii) or (iv) above, such Gross Asset Value      
  shall thereafter be adjusted by the Depreciation taken into account with
  respect to such asset for purposes of computing Profits and Losses.
  Section 10.16. New Partners. The Partnership Interests of additional Partners
shall not be entitled to any retroactive allocation of the Partnership's
income, gains, losses, deductions, credits or other items; provided that,
subject to the restrictions of Section  706(d) of the Code, the Partnership
Interests of additional Partners shall be entitled to their respective share of
the Partnership's income, gains, losses, deductions, credits and other items
arising under contracts entered into before the effective date of the issuance
of any such interests to the extent that such income, gains, losses,
deductions, credits and other items arise after such effective date.  To the
extent consistent with Section  706(d) of the Code and Treasury Regulations
promulgated thereunder, the Partnership's books may be closed at the time the
Partnership Interests of additional Partners are issued (as though the
Partnership's tax year had ended) or the Partnership may credit to the
additional Partners pro rata allocations of the Partnership's income, gains,
losses, deductions, credits and items for that portion of the Partnership's
Fiscal Year after the effective date of the issuance of the Partnership
Interests of additional Partners.
  Section 10.17. Sales; Transfers. The provisions of this LP Agreement shall
inure to the benefit and be binding upon the Parties hereto and their
successors and assigns.  The Partners agree that if any one of them makes a
Transfer of its Partnership Interest under this LP Agreement, such Transfer
will be structured, if possible, so as not to cause a termination under Code
Section 708(b)(1)(B).  If a Code Section 708(b)(1)(B) termination is caused,
the terminating Partner will indemnify the non-terminating Partners and save
them harmless for any increase in taxes, interest, and penalties or decreases
in credits caused by such termination.  As between any Partner and its
Transferee, Profits and Losses for the Fiscal Year of the Partnership in which
such assignment occurs shall be apportioned for federal income tax purposes in
accordance with any convention permitted under Section 706(d) of the Code and
determined by the TMP.
  Section 10.18. Deficit Capital Account on Liquidation. In the event the
Partnership is "liquidated" within the meaning of Treasury Regulation, Section
1.704-1(b)(2)(ii)(g):
  (a) (i) subject to Section 13.04(a) hereof, distributions shall be made
pursuant to this Section 10.18 to the Partners who have positive Capital
Accounts in compliance with Treasury Regulations Section
1.704-1(b)(2)(ii)(b)(2) and, (ii) if any




                                      35
LP Agreement                                                           
<PAGE>   36
General Partner's Capital Account has a deficit balance (after giving effect to
all contributions, distributions, and allocations for all Fiscal years,
including the Fiscal Year during which such liquidation occurs), such Partner
shall contribute to the capital of the Partnership the amount necessary to
restore such deficit balance to zero in compliance with Treasury Regulations
Section 1.704-1(b)(2)(ii)(b)(3), provided, that no General Partner shall be
obligated to contribute to the capital of the Partnership any amount in excess
of such General Partners' pro rata share of the aggregate amount of recourse
Partnership liabilities approved or provided for under Section 8.06 hereof.
  (b) If any Limited Partner has a deficit balance in its Capital Account
(after giving effect to all contributions, distributions, and allocations for
all Fiscal Years, including the Fiscal Year during which such liquidation
occurs), such Limited Partner shall have no obligation to make any contribution
to the capital of the Partnership with respect to such deficit, and such
deficit shall not be considered a debt owed to the Partnership or to any other
Person for any purpose whatsoever.
  (c) In the discretion of the General Partners, a pro rata portion of the
distributions that would otherwise be made to the Partners pursuant to
paragraph (a) of this Section 10.18 may be:
  (i) distributed to a trust established for the benefit of the Partners for
  the purposes of liquidating Partnership assets, collecting amounts owed to
  the Partnership, and paying any liabilities or obligations of the Partnership
  or of the General Partners arising out of or in connection with the
  Partnership.  The assets of any such trust shall be distributed to the
  Partners from time to time, in the reasonable discretion of the General
  Partners in the same proportions as the amount distributed to such trust by
  the Partnership would otherwise have been distributed to the Partners
  pursuant to Section 13.04(b) hereof; or
  (ii) withheld to provide a reasonable reserve for Partnership liabilities 
  (contingent or otherwise) and to reflect the unrealized portion of any 
  installment obligations owed to the Partnership, provided that such 
  withheld amounts shall be distributed to the Partners as soon as 
  practicable.

                                   ARTICLE XI
              ASSIGNABILITY; ADMISSION AND WITHDRAWAL OF PARTNERS

         Section 11.01. Assignability of a General Partner's Interest in the
Partnership. A General Partner shall neither Transfer nor  pledge, encumber,
mortgage, or otherwise hypothecate (hereinafter in this Article XI collectively
referred to as "assign" or "assignment") the whole or any part of its interest
as a General Partner in the Partnership without the prior Consent of the other
Partners.  An assignee of all or part of the interest of a General Partner in
the Partnership shall be admitted to the Partnership as a general partner of
the Partnership only if (i) the other Partners Consent to the admission of such
assignee as an additional or

<PAGE>   37
successor General Partner, and (ii) such assignee agrees in writing to accept
and adopt the terms and provisions of this LP Agreement.  If such conditions
are satisfied, the admission shall be effective upon the filing of an amendment
to the Certificate of Limited Partnership with the Secretary of State which
indicates that such Person has been admitted to the Partnership as a general
partner of the Partnership.  If a General Partner Transfers all of its
Partnership Interest and a successor General Partner is admitted, in accordance
with this Section 11.01, the admission of the successor General Partner shall
occur, and for all purposes shall be deemed to have occurred, immediately prior
to the time the Transferor ceases to be a general partner of the Partnership.
Such Transferor shall cease to be a general partner of the Partnership upon the
filing of an amendment to the Certificate of Limited Partnership with the
Secretary of State which indicates that such Transferor is no longer a general
partner of the Partnership.  Such Transferee and the other General Partners are
hereby authorized to and shall continue the Partnership without dissolution.
         Section 11.02. Assignability of a Limited Partner's Interest in the
Partnership. No Limited Partner may assign the whole or any part of its
interest in the Partnership without the prior unanimous Consent of the General
Partners, which Consent shall not be unreasonably withheld (taking into account
the best interests of the Partnership).  If the prior Consent of all General
Partners is obtained for any such assignment, such assignment shall,
nevertheless, not entitle the assignee to become a Substituted Limited Partner
or to be entitled to exercise or receive any of the rights, powers or benefits
of a Limited Partner unless the assigning Limited Partner designates, in a
written instrument delivered to the General Partners, its assignee to become a
Substituted Limited Partner and the General Partners, in their sole discretion,
Consent to the admission of such assignee as a Limited Partner; and provided
further, that such assignee shall not become a Substituted Limited Partner
without (i) having first executed an instrument in form and substance
satisfactory to the General Partners accepting and adopting the terms and
provisions of this LP Agreement, including, if requested by the General
Partners, a counterpart signature page to this LP Agreement, and (ii) having
paid to the Partnership, in cash, a fee sufficient to cover all reasonable
expenses of the Partnership in connection with its admission as a Substituted
Limited Partner.
         Section 11.03. Recognition of Assignment by Partnership. No
assignment, or any part thereof, that is in violation of this Article XI shall
be valid or effective, and neither the Partnership nor the General Partners
shall recognize the same for the purpose of making distributions of Net Cash
Flow pursuant to Section 6.01 with respect to such Partnership Interest, or
part thereof.  Neither the Partnership nor the General Partners shall incur any
liability as a result of refusing to make any such distributions to the
recipient of any such invalid assignment.
         Section 11.04. Effective Date of Assignment. Any valid assignment of a
Limited Partner's interest in the Partnership, or




                                      37
LP Agreement

part thereof, pursuant to Section 11.02 shall be effective as of the close of
business on the last day of the calendar month in which the General Partners
give their written consent to such assignment (or the last day of the calendar
month in which such assignment occurs, if later).  The Partnership shall, from
the effective date of such assignment, thereafter pay all further distributions
of Net Cash Flow, on account of the Partnership Interest (or part thereof) so
assigned, to the assignee of such interest, or part thereof.  As between any
Partner and its assignee, Profits and Losses for the fiscal year of the
Partnership in which such assignment occurs shall be apportioned for federal
income-tax purposes in accordance with any manner permitted under Section
706(d) of the Code as such Partner and its assignee may agree to.
         Section 11.05. Death, Incompetency, Bankruptcy, or Dissolution of a
Limited Partner. The death, incompetency, Bankruptcy, dissolution or other
cessation to exist as a legal entity of a Limited Partner shall not, in and of
itself, dissolve the Partnership.  In any such event, the legal representative
or successor of such Limited Partner may exercise all of the rights of such
Limited Partner for the purpose of settling its estate or administering its
property, subject to the terms and conditions of this LP Agreement, including
any power of an assignee to become a Limited Partner.
         Section 11.06. Withdrawal from the Partnership. Except as specifically
provided in this LP Agreement, a General Partner or a Limited Partner may not
withdraw as a general partner of the Partnership or as a limited partner of the
Partnership, as the case may be.
         Section 11.07. Removal of General Partner. A General Partner may be
removed as a general partner of the Partnership with or without cause upon (i)
the unanimous Consent of the Limited Partners and (ii) the election by such
Limited Partners of a successor General Partner.  Upon any such election, all
Partners shall be bound thereby and shall be deemed to have approved thereof.
Such successor General Partner shall be deemed admitted to the Partnership
immediately prior to the removal of the predecessor General Partner and shall
continue the Partnership without dissolution.  A successor General Partner
shall be admitted as a general partner of the Partnership upon the filing of an
amendment to the Certificate of Limited Partnership with the Secretary of State
which indicates that the successor General Partner has been admitted as a
general partner of the Partnership and that the removed General Partner is no
longer a general partner of the Partnership.

                                  ARTICLE XII
                       EXCULPATION AND INDEMNIFICATION OF
               THE GENERAL PARTNERS AND OTHER INDEMNIFIED PERSONS

         Section 12.01. Exculpatory Provisions.
         (a) Covered Persons. Notwithstanding any other terms of this LP
Agreement, whether express or implied, or obligation or duty at law or in
equity, neither the General Partners, their Affiliates, nor any of their
respective Representatives, Alternate Representatives, officers, directors,
shareholders, partners, employees, or agents nor any Partnership Official or
any other officer, employee, representative or agent of the Partnership and its
Affiliates (individually, a "Covered Person" and collectively, the "Covered
Persons") shall be liable to the Partnership or any Partner for any act or
omission (in relation to the Partnership, this LP Agreement, any related
document or any transaction or investment contemplated hereby or thereby) taken
or omitted in good faith by a Covered Person and in the reasonable belief that
such act or omission is in or is not contrary to the best interests of the
Partnership and is within the scope of authority granted to such Covered Person
by this LP Agreement, provided that such act or omission does not constitute
Disabling Conduct.
         (b) Reliance. A Covered Person may rely and shall incur no liability
in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond,
debenture, paper, document, signature or writing reasonably believed by it to
be genuine, and may rely on a certificate signed by an officer of any Person in
order to ascertain any fact with respect to such Person or within such Person's
knowledge and may rely on an opinion of counsel reasonably selected by such
Covered Person with respect to legal matters unless such Covered Person acts in
bad faith.
         (c) Fiduciary Duty. To the extent that, at law or in equity, a Covered
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Partnership or to any other Covered Person, a Covered Person acting
under this LP Agreement shall not be liable to the Partnership or to any other
Covered Person for its good faith reliance on the provisions of this LP
Agreement. The provisions of this LP Agreement, to the extent that they
restrict the duties and liabilities of a Covered Person otherwise existing at
law or in equity, are agreed by the parties hereto to replace such other duties
and liabilities of such Covered Person.
         Section 12.02. Indemnification of General Partner and Other
Indemnified Persons.
         (a) Scope of Indemnity. To the fullest extent permitted by Applicable
Law, the Partnership shall indemnify and hold harmless each General Partner,
its Affiliates and all directors, officers, shareholders, partners, employees,
Representatives, Alternate Representatives and agents of each General Partner
and its Affiliates and all Partnership Officials and all other officers,
employees, representatives and agents of the Partnership and its

<PAGE>   40
Affiliates (individually, an "Indemnified Person" and collectively, the
"Indemnified Persons") from and against any and all losses, claims, demands,
liabilities, expenses (including all fees and expenses), judgments, fines,
settlements, and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or
investigative, in which the Indemnified Person may be involved, or threatened
to be involved, as a party or otherwise, by reason of its involvement with the
management of the affairs of the Partnership, or a General Partner or its
status as a General Partner, an Affiliate thereof, or partner, director,
officer, stockholder, employee, representative or agent thereof or of the
Partnership or a Person serving at the request of the Partnership, a General
Partner or any Affiliate thereof in another entity in a similar capacity, which
relates to or arises out of the Partnership, its property, its business or
affairs, and regardless of whether the liability or expense accrued at or
relates to, in whole or in part, any time before, on or after the date hereof.
The adverse disposition of any action, suit or proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere, or its equivalent,
shall not, of itself, create a presumption that the Indemnified Person acted in
a manner contrary to the standard set forth in Section 12.02(b) below.  Any
indemnification pursuant to this Section 12.02 shall be made only out of the
assets of the Partnership.
         (b) Limitation. An Indemnified Person shall not be entitled to
indemnification under this Section 12.02 with respect to any claim, issue or
matter in which it (i) has a right of indemnity under Section 8.09(g), or (ii)
has engaged in Disabling Conduct; provided, however, that a court of competent
jurisdiction, may determine upon application that, despite such Disabling
Conduct, in view of all the circumstances of the case, the Indemnified Person
is fairly and reasonably entitled to indemnification for such liabilities and
expenses as the court may deem proper.
         (c) Expenses. To the fullest extent permitted by law, expenses
(including legal fees) incurred by an Indemnified Person in defending any
claim, demand, action, suit or proceeding shall, from time to time, be advanced
by the Partnership prior to the final disposition of such claim, demand,
action, suit or proceeding upon receipt by the Partnership of an undertaking by
or on behalf of the Indemnified Person to repay such amount if it shall be
determined that the Indemnified Person is not entitled to be indemnified as
authorized in Section 12.02.
         (d) Other Rights. The indemnification provided by Section 12.02 shall
be in addition to any other rights to which an Indemnified Person may be
entitled under any agreement, by law or vote of the Partners as a matter of law
or otherwise, both as to action in the Indemnified Person's capacity as a
General Partner, an Affiliate thereof or a partner, director, officer,
stockholder, partner, representative, employee or agent thereof, or an officer,
employee, representative or agent of the Partnership or an Affiliate thereof
and, as to action in any other capacity, shall continue as to an Indemnified
Person who has ceased to serve in




                                      40
LP Agreement

such capacity and shall inure to the benefit of the heirs, successors, assigns
and administrators of an Indemnified Person.  The General Partners and the
Partnership may enter into indemnity contracts with Indemnified Persons and
adopt written procedures pursuant to which arrangements are made for the
advancement of expenses and the funding of obligations under this Section 12.02
and containing such other procedures regarding indemnification as are
appropriate.
         (e) Insurance.
         (i) Liability. Each General Partner shall at all times maintain
         commercial or comprehensive general liability insurance coverage to
         include blanket contractual and broad-form liability endorsements, or
         their equivalents, completed operations coverage and, when applicable,
         products coverage, with minimum limits of $100 million.  The
         Partnership shall, in addition, purchase primary liability coverage in
         the form of a "joint venture" or similar policy approved by the
         General Partners with limits of at least $5 million.
         (ii) All-Risk/Property. All of the Partnership's assets, including,
         without limitation, the Facility and the Pipeline, shall be insured
         under an all-risks property insurance policy approved by the General
         Partners, with limits of coverage sufficient to provide coverage for
         all of the Partnership's equipment and other fixed assets, and also
         including business interruption and pollution coverage if available on
         reasonable terms, as the General Partners may approved from time to
         time.
         (iii) Directors and Officers. Unless otherwise approved by the General
         Partners, the Partnership shall not procure or provide "Directors and
         Officers" or similar liability coverage for any Person, and each
         General Partner may provide such coverage for any individual acting in
         connection with the Partnership's business at such General Partner's
         behest.
         (iv) Other Insurance. The Partnership may maintain in existence any
         and all other forms of insurance coverage necessary, appropriate or
         customary to the Partnership's business, as approved from time to time
         by the General Partners, including, without limitation, automobile,
         workmen's compensation, crime, and other standard coverages.
         (f) No Liability to Limited Partners. In no event may any Indemnified
Person subject the Limited Partners to personal liability by
reason of any indemnification of an Indemnified Person under this LP Agreement
or otherwise.
         (g) Interest in Transaction. An Indemnified Person shall not be denied
indemnification in whole or in part under this Section 12.02 because the
Indemnified Person had an interest in the transaction with respect to which the
indemnification applies if the transaction is otherwise permitted by the terms
of this LP Agreement.
         (h) Benefit of Indemnity. The provisions of Section 12.02 are for the
benefit of the Indemnified Persons and shall not be deemed to be for the
benefit of any other Persons.

         Section 13.01. No Dissolution. The Partnership shall not be dissolved

when the assignee has not been admitted to the Partnership as a successor
General Partner in accordance with Section 11.01, or the occurrence of any
other event that results in any General Partner ceasing to be a general partner
of the Partnership under the Act, provided that, the Partnership shall not be
dissolved and required to be wound up in connection with any of the events
specified in this clause (b) if (i) at the time of the occurrence of such event
there is at least one remaining general partner of the Partnership who is
hereby authorized to and does carry on the business of the Partnership, or (ii)
within ninety (90) days after the occurrence of such event, all remaining
Partners agree in writing to continue the business of the Partnership and to

more successor general partners of the Partnership;
         (c) A written determination by the General Partners to dissolve the

to minimize the normal losses attendant upon a liquidation.  The Partners shall
continue to receive allocations of Profits and Losses during liquidation in the
same proportions as specified in Article V as before liquidation.  Each Partner
shall be furnished with a statement prepared by the Partnership's certified
public accountant that shall set forth the assets and liabilities of the
Partnership as of the date of dissolution.  The proceeds of liquidation shall
be distributed, as realized, in the following order and priority:
         (a) To creditors of the Partnership, including any Partners or their

satisfaction of the liabilities of the Partnership (whether by payment or the

liquidated by either:
         (a) Selling the Partnership assets and distributing the net proceeds
therefrom in the manner provided in Section 13.04.  Any net gain or loss
realized by the Partnership on the sale or other disposition of Partnership
assets in the process of liquidation of the Partnership shall be allocated to
the Partners' Capital Accounts in proportion to their respective Partnership
Interests; or
         (b) If unanimously Consented to by all Partners at such time, and
subject to the order of priority set forth in Section 13.04, distributing the
Partnership assets proportionately to the Partners in kind with each Partner
accepting an undivided interest in the Partnership assets, subject to
Partnership liabilities, in satisfaction of its proportionate interests in the
Partnership.  For the purpose of determining the amount distributed to each
Partner, any property distributed in kind in the liquidation shall be valued at
Appraised Fair Market Value.
         Section 13.06. Termination of Partnership. The Partnership shall
terminate when all of the assets of the Partnership, after payment of or due

tax purposes, the Partnership shall be deemed to have distributed the
Partnership's assets in kind to the Partners, who shall be deemed to have
assumed and taken subject to all Partnership liabilities, all in accordance
with their respective Capital Accounts and, if any General Partner's Capital
Account has a deficit balance (after giving effect to all contributions,
distributions, and allocations for all Fiscal Years, including the Fiscal Year
during which such liquidation occurs), such General Partner shall, subject to
the limitation in Section 10.18(b) hereof, contribute to the capital of the
Partnership the amount necessary to restore such deficit balance to zero in
compliance with Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(3).
Immediately thereafter, the Partners shall be deemed to have recontributed the
Partnership's assets in kind to the Partnership, which shall be deemed to have
assumed and taken subject to all such liabilities.

                               DISPUTE RESOLUTION

         Section 14.01. Arbitration. To the fullest extent permitted by the Act
and other Applicable Law, any controversy or claim arising out of or relating
to this LP Agreement, or any breach thereof, shall be settled by arbitration in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association ("AAA"), as amended and in effect on the date that demand for
arbitration is filed with the AAA.  Each Party hereto agrees that any such
controversy shall be submitted to a single arbitrator if agreed to by the
parties to the arbitration.  Otherwise, each party to the arbitration shall
select one arbitrator, and the two arbitrators selected shall then choose a
third arbitrator.  The ruling of the arbitrator(s) shall be binding and
conclusive upon the Parties hereto to the fullest extent permitted by law.  Any
arbitration shall occur in Baltimore, Maryland, or any other location agreed to
in writing by the parties to the arbitration, and judgment upon the award
rendered may be entered in any court having jurisdiction thereof.  The
arbitrator(s) shall be governed by and shall apply the substantive law of the
State of Delaware in making their award.  The expenses of the arbitration shall
be borne equally by the parties to the arbitration, and each such party shall
pay for and bear the cost of its or its own experts, evidence and legal
counsel, unless the arbitrator(s) determine(s) that any party to the
arbitration proceeded in bad faith, or asserted meritless claims or positions,
in which event the arbitrator(s) shall be empowered to award the other party
all or part of the reasonable costs of such arbitration.

         Section 16.02. Amendments.
         (a) Amendments with the Consent of Limited Partners. Except as
provided in Section 16.02(b), no amendment to this LP Agreement shall be
effective or binding upon the Parties hereto without the written Consent of all
General Partners and a Majority Vote; provided, however, that any modification
or amendment that would: (i) increase the amount of the capital contributions
to be made by any Partner, (ii) increase the liability of the Limited Partners,
or (iii) materially adversely affect the rights of the Limited Partners under
this LP Agreement shall require the Consent of all General Partners and all
Limited Partners.  Upon receipt of a written proposal executed by all Limited
Partners for the adoption of an amendment of this LP Agreement, or should the
General Partners desire to propose such an amendment, the General Partners
shall adopt and implement a plan whereby the Limited Partners may vote for or
against the adoption of such an amendment.
         (b) Amendments Without Limited Partner Consent. Notwith-standing
anything herein to the contrary, the General Partners may amend this LP
Agreement without the consent of any Limited Partner:
         (i) to reflect the addition or substitution of Limited Partners (made
         in accordance with the terms hereof) or the reduction of the Capital
         Accounts upon the return of capital to Limited Partners;
         (ii) to add to the representations, duties or obligations of the
         General Partners or surrender any right or power granted to the
         General Partners herein, for the benefit of the Limited Partners;
         (iii) to cure any ambiguity, to correct or supplement any provision
         herein which may be inconsistent with any other provision herein, or
         to add any other provisions with respect to matters or questions
         arising under this LP Agreement which will not be inconsistent with
         the provisions of this LP Agreement;

         (iv) to delete or add any provision from or to this LP Agreement
         requested to be so deleted or added by the staff of the SEC or by a
         state regulatory agency, the deletion or addition of which provision
         is deemed by such staff or such regulatory agency to be for the
         benefit or protection of the Limited Partners; and
         (v) to modify any provision of this LP Agreement, if, in the opinion
         of counsel to the Partnership and the General Partners, such
         modification is necessary to prevent the Partnership or the Partners
         from in any manner being regulated as a registered holding company or
         non-exempt subsidiary thereof under PUHCA, as amended, to prevent the
         Partnership from being treated for tax purposes as an association
         taxable as a corporation, rather than being taxable as a partnership,
         or to prevent the Partnership from being treated as a "publicly traded
         partnership" as defined in the Code.
         Section 16.03. Fiscal Year. The "Fiscal Year" of the Partnership shall
be the calendar year commencing at 12:01 a.m. on January 1 of each year and
ending at 12:00 midnight on December 31 of each year.
         Section 16.04. Securities Act Investment Covenant. Each Partner
represents and warrants that it is acquiring its interest in the Partnership
for its own account, and not with a view to resale or distribution thereof
within the meaning of the Securities Act of 1933, as amended, and that no such
interest will be sold, transferred, hypothecated, or assigned by it in
contravention of the Securities Act of 1933, as amended, or any state Blue Sky
or securities statute.
         Section 16.05. Failure to Pursue Remedies. The failure of any Party to
seek redress for violation of, or to insist upon the strict performance of, any
provision of this LP Agreement shall not prevent a subsequent act, which would
have originally constituted a violation, from having the effect of an original
violation.
         Section 16.06. Headings. The headings in this LP Agreement are
included for convenience and identification only and are in no way intended to
describe, interpret, define or limit the scope, extent or intent of this LP
Agreement or any provision hereof.
         Section 16.07. Cumulative Remedies. The rights and remedies provided
by this LP Agreement are cumulative and the use of any one right or remedy by
any Party shall not preclude or waive its right to use any or all other
remedies.  Said rights and remedies are given in addition to any other rights
the Parties may have by law, statute, ordinance or otherwise.
         Section 16.08. Binding Effect. This LP Agreement shall be binding upon
and inure to the benefit of all the Parties and, to the extent permitted by
this LP Agreement, their successors, legal representatives, and assigns.
         Section 16.09. Interpretation. Throughout this LP Agreement and any
amendment hereto, nouns, pronouns, and verbs shall be construed as masculine,
feminine, neuter, singular or plural, whichever shall be applicable.

         Section 16.10. Severability. The invalidity or unenforceability of any
particular provision of this LP Agreement shall not affect the other provisions
hereof, and this LP Agreement shall be construed in all respects as if such
invalid or unenforceable provision were omitted.
         Section 16.11. Counterparts. This LP Agreement may be executed in any
number of counterparts with the same effect as if all Partners had signed the
same document.  All counterparts shall be construed together and shall
constitute one instrument.
         Section 16.12. Whole Agreement. This LP Agreement and Appendices A, B
and C annexed hereto, each of which is made a part hereof by this reference,
contain the entire "partnership agreement" of the Partnership for purposes of
the Act and, except as otherwise provided herein, may be changed only by
written amendment.  There are no oral understandings or agreements between the
Parties upon the subject matter of this LP Agreement, and any prior written
agreements as to the governance of the affairs of the Partnership, including,
without limitation, the Original Partnership Agreement, are hereby superseded
and merged herein, except only as herein otherwise expressly stated.
         Section 16.13. Governing Law. This LP Agreement and the rights of the
parties hereunder shall be interpreted in accordance with the laws of the State
of Delaware, and all rights and remedies shall be governed by such laws without
regard to principles of conflicts of laws.

hereto (the "Warranting Party") represents and warrants to each other Party
hereto, and each such other Party in agreeing to enter into this LP Agreement
has relied upon such representations and warranties, that:
         (a) The Warranting Party has the requisite power and authority,
corporate and otherwise, to execute and deliver this LP Agreement and to
perform its duties and obligations hereunder, and any Person signing this LP
Agreement on behalf of a Warranting Party is duly authorized, empowered and
directed to sign this LP Agreement on such Warranting Party's behalf;
         (b) This LP Agreement has been duly and validly executed by the
Warranting Party and, assuming the due execution and delivery of this LP
Agreement by all other Parties hereto, constitutes the Warranting Party's valid
and binding obligation, enforceable against the Warranting Party in accordance
with the terms hereof, except to the extent that such enforceability may be
limited by bankruptcy, insolvency, reorganization or other similar laws
relating to creditors' rights generally or general principles of equity; and
         (c) Except for the Initial FERC Certificate, and the approvals
contemplated by Section 18.01, no consent, approval, or other authorization by
any judicial, governmental or regulatory authority, domestic or foreign, or any
third party, is required to be obtained by the Warranting Party in connection
with the valid execution, delivery, and performance by the Warranting Party of

         Section 16.15. No Rights of Third Parties. None of the provisions of

                          PROJECTS; FERC APPLICATIONS

         Section 17.01. Scope of the Initial Project. The first Project
undertaken by the Partnership shall consist of the construction of the
Liquefaction Unit at the Cove Point Site, alterations and improvements to the
Facility to integrate the Liquefaction Unit as part of the Facility, and such
other refurbishments to the Facility as are necessary to enable the Partnership
to engage in the Peaking Business and the Transportation Business (the "Initial
Project").  Prior to the Construction Capital Closing, the Partners shall use
best efforts to cooperate in maximizing the peaking revenues and volumes
represented by the Service Agreements.
         Section 17.02. The Initial FERC Application.
         (a) Diligent Prosecution. After execution of this LP Agreement, the
Partnership shall continue to diligently prosecute the Initial FERC Application
seeking certificate authority to permit the Partnership to acquire and own the
Facility, to construct and operate the Initial Project, and to carry on the
Peaking Business and the Transportation Business.  All Partners hereby agree to
cooperate in the prosecution thereof, including any amendments, modifications,
appeals or similar actions deemed necessary from time to time by the General
Partners.
         (b) Acceptance by Partnership. If and when the Initial FERC
Certificate is granted to the Partnership either (i) in the form and substance
requested in the Initial FERC Application, as the same may have been amended or
modified to the satisfaction of the General Partners from time to time, with no
material alterations or modifications on the part of the FERC, or (ii) if not
granted as specifically requested, if the Initial FERC Certificate would
otherwise permit the Partnership to proceed with the Initial Project in all
material respects without detriment to any Partner, such Initial FERC
Certificate shall be automatically accepted by the Partnership with no approval
or other action being necessary by any Partner.  In the event that the Initial
FERC Certificate is not subject to such automatic acceptance, the General
Partners may, upon their sole discretion, nonetheless cause the Partnership to
accept any Initial FERC Certificate issued by the FERC.  In either event, upon
acceptance by the Partnership of the Initial FERC Certificate, the Partnership
shall forthwith proceed to construct and operate the Initial Project after the
Construction Capital Closing Date subject to satisfaction or waiver of the
other conditions precedent set forth in Section 18.02.

         (c) Right to Withdraw. If the Initial FERC Certificate is not accepted
in accordance with Section 17.02(b), any Partner shall have the right to
withdraw from the Partnership prior to the Construction Capital Closing Date by
giving written Notice to the other Partners.  Subject to the Act, upon such
withdrawal of any Partner, the remaining Partners may elect, on such terms as
they deem advisable in their sole discretion, to continue the existence of the
Partnership and cause it to continue with the Initial Project to the extent of
the Partnership's rights, if any, to use the Facility for such purpose.
         Section 17.03. Additional Projects. (a) In the event that the
Partnership is presented with an opportunity to expand the Peaking Business,
initiate a baseload LNG import trade or to pursue other opportunities with
respect to expansion of the Facility, including power generation, and the
Partnership's pursuit of such activities is approved by unanimous Consent of
all Partners, Capital Contributions required to fund such Additional Projects
will be made by, and the economic benefits of such Additional Projects will be
shared by each Partner in proportion to such Partner's Partnership Interest.
The Partners hereby agree that an express purpose of the Partnership shall be
to pursue the implementation of an ongoing baseload LNG import trade.
         (b) The General Partners shall cause the Partnership to develop,
market, construct and operate any such Additional Project following approval by
the General Partners of a Project Construction Plan, provided, that the
implementation thereof shall be subject to the Partnership first obtaining any
and all necessary consents and approvals of the FERC and any other applicable
Governmental Authorities, and further subject to any applicable and enforceable
restrictive covenants contained in the Sierra Club Agreement.  Any such
Additional Project for which a Project Construction Plan has been approved by
the General Partners shall, in the absence of a written agreement of all
Partners to the contrary, be funded jointly by all Partners upon Cash Calls
made in accordance with Section 4.04 of this LP Agreement, and/or through
external financing, including, without limitation, Project debt financing, to
the extent approved by the General Partners.
         Section 17.04. Project Construction Plan. For each Project proposed to
be constructed by the Partnership, the General Partners shall agree upon a
"Project Construction Plan" setting forth the scope of the Project and a plan
for administering, coordinating and supervising the design, construction and
permitting of the Project, including without limitation the proposed design
criteria, construction cost estimate and schedule, project milestone schedule
(including projected dates for the filing for and issuance of all necessary
regulatory permits through the projected In-Service Date for such Project), a
completion and testing protocol establishing the criteria to be satisfied to
establish the In- Service Date for such Project (the "Completion and Testing
Protocol"), an estimate of the operating and maintenance budget, marketing
plan, business plan and a cost-benefit analysis with respect to the Project,
and such other information as either of the General Partners may

reasonably request.  Each Project Construction Plan shall be in addition to the
Partnership's Annual Plan; however, all such plans and each annual Approved
Budget of the Partnership shall be coordinated with and consistent with each
other.  With respect to the Project Construction Plan for the Initial Project,
the General Partners shall use their best efforts to reach agreement upon such
Plan on or before the Construction Capital Closing Date, which Plan, in the
case of the Initial Project, shall not include the cost-benefit analysis
referred to above in this Section 17.04.

                ARTICLE XVIII. THE CONSTRUCTION CAPITAL CLOSING;
                           CERTAIN REGULATORY MATTERS

         Section 18.01. Partners' Regulatory Approvals.
         (a) Columbia Approvals. Notwithstanding anything to the contrary
contained herein, the Columbia Partners' obligations hereunder are expressly
conditioned upon the receipt by the Columbia Partners of the order requested on
December 8, 1993, from the SEC under PUHCA with respect to the transactions
contemplated hereby in substantially the form requested (or with such
modifications thereto as may be requested (x) by Columbia or the Columbia
Partners consistent with the Transaction Documents, or (y) by the SEC which do
not materially adversely affect the Columbia Partners) (the "SEC Order").  In
connection therewith, each of the Columbia Partners shall have the
unconditional right to withdraw from the Partnership at any time that the SEC
Order is denied by the SEC; or any of Columbia or the Columbia Partners
reasonably determines in good faith that further prosecution of the application
for the SEC Order is futile.
         (b) PEPCO Approvals. The PEPCO Partners shall take such actions and
make such filings as are necessary or appropriate to obtain any requisite
approvals of any public utility commissions or other regulatory agencies having
jurisdiction over their or their Affiliates' properties or the conduct of their
or their Affiliates' businesses.  Until such time as the Columbia Partners have
obtained the SEC Order, the PEPCO Partners shall have the unconditional right
to withdraw from the Partnership in the event that the PEPCO Partners are
denied any required regulatory approval reasonably satisfactory in form and
substance to the PEPCO Partners.
         (c) Cooperation. All Partners agree to diligently pursue and use their
best efforts to obtain their respective required regulatory approvals, and to
cooperate with the efforts of all other Partners and their respective
Affiliates in obtaining such regulatory approvals, and no Partner will take any
action contrary to or in opposition of any such Partner and/or such Partner's
Affiliates obtaining such approvals.  In connection therewith, each of the
Partners agrees to join in and execute any such filings, in a timely manner, as
the other Partner and/or such Partner's Affiliates reasonably request and take
all such other actions as may be necessary and appropriate in order to obtain
the necessary approvals from all regulatory authorities having jurisdiction
over the transactions contemplated hereby (collectively, the "Regulatory




                                      51

Approvals").  If at any time either Partner receives information from any
regulatory agency or other Governmental Authority, which by Applicable Law is
required to approve, or which has the authority to challenge the validity of,
the transactions contemplated hereby, in judicial proceedings or otherwise,
that provides a high probability for such Partner to conclude in good faith
that the required Regulatory Approval will not be granted or that the
transactions contemplated hereby or in the Transaction Documents will be so
challenged, such Partner shall immediately Notify the other Partners, and the
Partners shall confer as to the appropriate action to be taken in response
thereto.
         Section 18.02. Conditions Precedent to Construction Capital Closing.
         (a) General Conditions. The obligation of each of the Partners to
perform its obligations hereunder at the Construction Capital Closing shall be
subject to the satisfaction, or waiver in writing by such Partner, on or prior
to the Construction Capital Closing, of each of the following conditions:
         (i) FERC Approval. The Partnership shall have accepted the Initial
         FERC Certificate in the manner provided in Section 17.02, and the
         Initial FERC Certificate shall be in full force and effect and not
         subject to any further review or reconsideration by any Governmental
         Authority;
         (ii) Regulatory Approvals. Each Partner's necessary Regulatory
         Approvals shall have been received and shall be final (not subject to
         any further administrative or judicial review or reconsideration) and
         in full force and effect, with all required waiting periods (if any)
         having expired ("Final Regulatory Approval");
         (iii) Service Agreements. The Partnership shall have obtained executed
         Service Agreements for a Peaking Business substantially equivalent to
         the "Nominated Revenues Business Plan" projections dated October 22,
         1993, or such other level of executed Service Agreements as may be
         agreed upon by the General Partners;
         (iv) Sierra Club Agreement. The Sierra Club Agreement shall have been
         duly executed and delivered by each of the parties thereto, and shall
         be in full force and effect and fully assignable to the Partnership as
         provided herein and therein;
         (v) Transaction Documents. Each of the Transaction Documents shall
         have been duly executed and delivered by each of the Parties thereto,
         and shall be in full force and effect and the conditions precedent to
         the transactions contemplated thereby shall have been satisfied or
         waived;
         (vi) Absence of Injunction. No Governmental Authority shall have
         issued any injunction, cease and desist order or similar restraint
         upon the performance by any of the Partners or their Affiliates of

          The Class 2.1 Claim is impaired.

          3.       CLASS 3 CLAIMS - UNSECURED CLAIMS

          a.       SETTLEMENT VALUES

          A dollar amount (a "Settlement Value") has been proposed for (i) each

Claim in Classes 3.3A, 3.3D, 3.4 and 3.5A, identified as such prior to the Plan

Mailing Date, and (ii) each of those Claims in Classes 3.1, 3.2, 3.3B, 3.6, 3.7

and 3.8 identified as such prior to the Plan Mailing Date for which TCO

believes it has sufficient information to formulate an





                                     - 42 -
<PAGE>   52
appropriate proposal.  The Settlement Values, determined as set forth below,

are listed on one of the schedules (one for each such class) annexed hereto as

Exhibits D-1 through D-10:

                 (i)  The Settlement Value proposed for each Settlement Value
          Claim which is an Allowed Claim as of the Plan Mailing Date is the
          Allowed amount of the Claim as of that date and accordingly is deemed
          accepted by the holder thereof without any further action on its
          part.

                (ii)  The Settlement Value proposed for each Settlement Value
          Claim which is not an Allowed Claim on the Plan Mailing Date is the
          amount at which TCO, in light of all the relevant facts known to it ,
          believes the Claim should, and consents to have the Claim, be
          Allowed.

               (iii)  The Settlement Value for each Claim in Class 3.3D has
          been determined by calculating such Claim in accordance with the same
          methodology as was used to determine the amount of each Class 3.3C
          Claim for the purpose of making distributions under the Enterprise
          Energy Settlement Agreement and multiplying the amount so determined
          for each such Claim by a fraction, the numerator of which is $30
          million and the denominator of which is the aggregate of all Claims
          settled under the Enterprise Energy Settlement Agreement as the same
          were calculated for the purpose of receiving distributions
          thereunder.

                (iv)  The Settlement Values for Class 3.4 are calculated as of
          the date set forth on Exhibit D-6 and will be adjusted as of the
          Effective Date to reflect refunds received by TCO subsequent to such
          calculation date.

          Each holder of a Settlement Value Claim that agrees to accept the

Settlement Value proposed for its Claim will be deemed to have agreed to have

its Claim Allowed at its Settlement Value and the Claim will, subject to

Bankruptcy Court approval, be so Allowed, as of the Voting Deadline, for voting

and distribution purposes, in the Class in which such Claim is classified by

virtue of such allowance.  If the holder of a Settlement Value





                                     - 43 -
<PAGE>   53
Claim does not agree to accept the proposed Settlement Value, allowance of its

Claim will be determined by litigation before the Claims Mediator or the

Bankruptcy Court or by settlement approved by the Bankruptcy Court.  If the

Plan is not consummated for any reason, the agreement to accept a Settlement

Value may be nullified at the option of the holder of the Claim by written

notice to TCO in accordance with such procedure as shall be determined by the

Bankruptcy Court.

          Settlement Value Claims (other than Claims in Classes 3.1, 3.3C, and

3.3D, which are unimpaired and accordingly are not voted on the Plan) (i) if

Allowed as of the Voting Deadline, whether by acceptance of its proposed

Settlement Value or otherwise, may be voted at its Allowed amount, or (ii) if

Disputed as of the Voting Deadline, may be allowed for voting purposes at its

proposed Settlement Value if one is proposed, or as otherwise determined by

order of the Bankruptcy Court.

          For certain of those Class 3.8 Claims for which no Settlement Value

has been proposed (the "Aggregate Settlement Value Claims") there is proposed

on Exhibit D-10 one amount (the "Aggregate Settlement Value") which is not

allocated among such Claims but which is the aggregate amount at which TCO, in

the light of all the relevant facts known to it, believes such Claims should,

and TCO will consent to have such Claims, be Allowed.

          If each of the Aggregate Settlement Value Claims is voted in favor of

the Plan, such votes shall be deemed an agreement among the holders of such

Claims and TCO that such Claims will,





                                     - 44 -
<PAGE>   54
subject to Bankruptcy Court approval, be Allowed at amounts which aggregate the

Aggregate Settlement Amount.  In such event, the amount at which each Aggregate

Settlement Value Claim will be Allowed will be determined by consent among the

parties, subject to Bankruptcy Court approval, or by the Bankruptcy Court

through the Claims Estimation Procedures or such other methodology as the

Bankruptcy Court may determine.  If the Plan is not consummated for any reason,

the agreement described in the first sentence of this paragraph may be

nullified at the option of the holder of any of the Aggregate Settlement Value

Claims by written notice to TCO in accordance with such procedure as shall be

determined by the Bankruptcy Court.

          If the holder of any of the Aggregate Settlement Value Claims does

not accept the proposed Aggregate Settlement Value, TCO may continue the Claims

Estimation Procedures with respect to such Claims and may petition the

Bankruptcy Court to establish the maximum aggregate amount at which such Claims

may be Allowed.

          b.       CLASS 3.1 - UNSECURED CLAIMS OF $50,000 OR LESS

          On the Effective Date, TCO shall pay to each holder of a Class 3.1

Claim that is then Allowed, cash in an amount equal to one hundred (100%)

percent of the Allowed amount of such Claim.  Any Class 3.1 Claim that becomes

an Allowed Claim after the Effective Date will be paid in cash its Allowed

amount on the forty-fifth day after the end of the Calendar Quarter in which

such Claim becomes an Allowed Claim.  See Section IV.B.2, "Claims Reserve for

Subsequently Allowed Non-General Fund Claims."  If





                                     - 45 -
<PAGE>   55
the Plan is not consummated, any voluntary reduction made by a holder of a

Claim in order to receive for such Claim the treatment provided for Class 3.1,

may be nullified at the option of the holder of the Claim by written notice to

TCO in accordance with such procedure as shall be determined by the Bankruptcy

Court.  Class 3.1 Claims are unimpaired.

          c.       CLASS 3.2 - UNSECURED CLAIMS IN EXCESS OF $50,000 BUT NOT 
                   IN EXCESS OF $250,000

          If Class 3.2 votes to accept the Plan, TCO shall pay to each holder

of an Allowed Class 3.2 Claim, cash in an amount equal to ninety-five (95%)

percent of the Allowed amount of such Claim, on the Effective Date, if the

Claim is then Allowed, or if not then Allowed, then on the forty-fifth day

after the end of the Calendar Quarter in which such Claim becomes an Allowed

Claim.  See Section IV.B.2, "Claims Reserve for Subsequently Allowed

Non-General Fund Claims."  In addition, after the occurrence of the Sharing

Event with respect to Class 3.2, each Claim in this Class will become a Sharing

Claim and each holder of an Allowed Class 3.2 Claim shall receive, from the

General Fund, distributions, in part in cash and in part in shares of Columbia

Stock (or, if Columbia so elects, entirely in cash), such that the value of the

recovery, as a percentage of the Allowed amount of the Claim, to each holder of

an Allowed Class 3.2 Claim shall equal, on the same percentage basis, the value

of the recovery to holders of Allowed General Fund Claims.  Such distributions

from the General Fund, if any, shall be made quarterly in accordance with the

Distribution Formula.

Fund Claims."

          If the Plan is not consummated, any voluntary reduction made by the

holder of a Claim in order to receive for its Claim the treatment provided for

TCO in accordance with such procedure as shall be determined by the Bankruptcy

Court.

Claim shall receive, from the General Fund, distributions, in part in cash and

in part in shares of Columbia Stock (or, if Columbia so elects, entirely in

cash), such that the value of the recovery, as a percentage of the Allowed

amount of the Claim, to each holder of an Allowed Class 3.3A Claim shall equal,

on the same percentage basis, the value of the recovery to holders of Allowed

General Fund Claims.

Energy Settlement Agreement.  Any contract rejection Claim arising from the

rejection of a gas purchase contract from which a Class 3.3C Claim arises shall

be deemed to arise from the rejection of such contract as the same is required

to be amended in accordance with the terms of the Enterprise Energy Settlement

Agreement and shall otherwise remain unaffected by the treatment of Class 3.3C

Claims under the Plan.

          Class 3.3C Claims are unimpaired.

          Each Accepting 3.3D Claimant shall receive a distribution in cash in

an amount equal to one hundred (100%) percent of the Allowed amount of its

Claim.  Any Class 3.3D Claim, the holder of which is not an Accepting 3.3D

Claimant will become a Class 3.7 Claim, will vote in Class 3.7 and, if it

becomes Allowed, will receive distributions in accordance with the Distribution

Formula.

          Any contract rejection Claim arising from the rejection of a gas

purchase contract from which a Class 3.3D Claim arises shall be deemed to arise

from the rejection of such contract as the same would be constituted if it were

to be amended in accordance with the terms of the Enterprise Energy Settlement

Agreement and shall otherwise remain unaffected by the treatment of Class 3.3D

Claims under the Plan.

          1.       NON-GENERAL FUND CLAIMS ALLOWED AS OF THE EFFECTIVE DATE

          Under the Plan, except as otherwise provided, or pursuant to orders

of the Bankruptcy Court, distributions to holders of Non-General Fund Claims

that are Allowed Claims as of the Effective Date will be made by TCO in cash on

the Effective Date, in accordance with the treatment provided for such

          2.       CLAIMS RESERVE FOR SUBSEQUENTLY ALLOWED NON-GENERAL FUND 
                   CLAIMS

          a.       GENERAL

          On the Effective Date, Reorganized TCO shall establish a reserve (the

"Claims Reserve") by depositing in a segregated interest bearing account, cash

equal to the maximum amount TCO in its discretion estimates is required to be

paid after the Effective Date and is not reserved for in the RIA Account, in

including any income earned thereon, net of applicable taxes, if any, on such

income, and any sums transferred to the Claims Reserve from the RIA Account,

shall be available to make the distributions provided for under the Plan to

Non-General Fund Claims which become Allowed after the Effective Date.  No

payments or distributions shall be made on account of any Non-General Fund

Claim until such Claim becomes an Allowed Claim.

<PAGE>   68
          b.       DISTRIBUTIONS FROM THE CLAIMS RESERVE

          Within forty-five (45) days after the end of each Calendar Quarter,

Reorganized TCO shall distribute from the Claims Reserve to each holder of a

Non-General Fund Claim (other than a Professional Claim or a Priority Tax

Claim) that became an Allowed Claim during such Calendar Quarter, the cash to

which such holder is entitled under the Plan to the extent not then or

theretofore paid from the RIA Account.  Each subsequently Allowed Professional

Claim and Priority Tax Claim shall be paid from the Claims Reserve in

accordance with the treatment set forth for such Claim in Section III.A,

"Treatment of Unclassified Claims."

          In the event that the funds in the Claims Reserve are insufficient to

make the distributions required to be made from the Claims Reserve, Reorganized

TCO shall, from its own funds, deposit into the Claims Reserve funds sufficient

to make the requisite distributions.  Such obligation of Reorganized TCO shall

be guaranteed by Columbia as part of the Columbia Guaranty.

          c.       DISTRIBUTION OF FUNDS REMAINING IN THE CLAIMS RESERVE

          From time to time, as any Disputed Non-General Fund Claim is Allowed

or otherwise disposed of at an amount requiring Plan distributions that are

less than the amount which have been reserved therefor in the Claims Reserve,

the amount reserved in the Claims Reserve in respect of such Disputed

Non-General Fund Claim may, at Reorganized TCO's discretion, either be

deposited into the RIA Account, or distributed to the General Fund Trustee.

Any cash remaining in the Claims Reserve after all objections to





                                     - 59 -
<PAGE>   69
Non-General Fund Claims have been resolved, all distributions have been made in

respect thereof and any transfers have been made to the RIA Account, shall be

distributed as soon as practicable to the General Fund Trustee.

          d.       TAX REQUIREMENTS FOR INCOME GENERATED BY THE CLAIMS RESERVE

          Reorganized TCO, as Disbursing Agent, or such third-party Disbursing

Agent as TCO may appoint pursuant to Section IV.D, shall pay, or cause to be

paid, out of the funds held in the Claims Reserve, any tax imposed by any

governmental unit on the income generated by the funds held in the Claims

Reserve and shall also file, or cause to be filed, any tax or information

return related to the Claims Reserve, and shall withhold with respect to any

distributions therefrom, as is required by any governmental authority.

          3.       RESERVE FOR DISSENTING 3.4 CLAIMANTS

          a.       GENERAL

          From and after the Effective Date, Reorganized TCO shall continue to

maintain the RIA Account for the purpose of segregating and holding the

Dissenting 3.4 Claimants Reserve Amount, any income that may be earned thereon

and any sums which may be transferred thereto from the Claims Reserve or

otherwise, and for effecting distributions to the Dissenting 3.4 Claimants

entitled thereto in accordance with any final disposition of the Refund

Disputes and the Plan.

          As of the Effective Date, the amount in the RIA Account shall be

adjusted to equal the Dissenting 3.4 Claimants Reserve





                                     - 60 -
<PAGE>   70
Amount.  To the extent the funds in the RIA Account on the Effective Date are

in an amount which is (i) less than the Dissenting 3.4 Claimants Reserve

Amount, TCO shall deposit an amount equal to such deficiency in the RIA

Account, on the Effective Date, or (ii) greater than the Dissenting 3.4

Claimants Reserve Amount, the excess shall be available to TCO for its funding

requirements under the Plan and otherwise.

          b.       DISTRIBUTIONS FROM THE RIA ACCOUNT

          Distributions from the RIA Account shall be made to Dissenting 3.4

Claimants in accordance with final resolutions, by orders not subject to

further review, of the Refund Disputes and with applicable law and FERC

regulations and in accordance with the Plan upon Allowance of their respective

Claims.  Any sums reserved in the RIA Account in respect of any Refund Claim

that is adjudicated or otherwise determined by Reorganized TCO to no longer be

required for the purpose for which it was reserved may, at Reorganized TCO's

discretion, be deposited into the Claims Reserve or distributed to the General

Fund Trustee.

          In the event the funds in the RIA Account are insufficient to make

the distributions required to be made from the RIA Account, Reorganized TCO

shall, from its own funds, deposit into the RIA Account funds sufficient to

make the requisite distributions.  Such obligation of Reorganized TCO shall be

guaranteed by Columbia as part of the Columbia Guaranty.

          c.       DISTRIBUTION OF FUNDS REMAINING IN THE RIA ACCOUNT

          Any cash remaining in the RIA Account after all Refund Disputes have

been resolved, all distributions have been made in respect thereof, all

distributions required under the Plan to Dissenting 3.4 Claimants have been

made and any transfers have been made to the Claims Reserve, shall be

distributed as soon as practicable to the General Fund Trustee.

C.        DISTRIBUTIONS TO HOLDERS OF GENERAL FUND CLAIMS

          1.       ESTABLISHMENT OF GENERAL FUND

          On the Effective Date, TCO shall establish a trust (the "General

Fund") to effect distributions to the holders of Allowed General Fund Claims by

delivering to the General Fund Trustee the amount of the General Fund Deposit,

of which $100 million shall be in the form of Columbia Stock and the balance

shall be in cash; provided, however, that Columbia may elect to have the

General Fund Deposit funded entirely in cash and provided further, that in lieu

of any portion of the General Fund Deposit consisting of cash not required for

distribution on the Effective Date, Reorganized TCO may, at its option, deliver

to the General Fund Trustee its unsecured promissory note (the "TCO Note"), in

such principal amount, bearing a rate of interest equal to the rate income is

earned from time to time on any cash in the General Fund, and payable in

installments when and as distributions are required to be made from the General

Fund, each such installment to be in an amount equal to that percentage of the

required distribution which the principal amount of the TCO





                                     - 62 -
<PAGE>   72
Note bears to the General Fund Distributable Amount.  Columbia, as part of the

Columbia Guaranty, shall guarantee the full, due and prompt payment by

Reorganized TCO of the TCO Note.  The terms of the TCO Note will be as proposed

by TCO and approved by the Bankruptcy Court on or before the Effective Date.

          The General Fund Trustee, and such entities as the General Fund

Trustee shall designate for such purpose, shall make the distributions required

under the Plan to be made from the General Fund in accordance with the

Distribution Formula described in Section IV.C.2.

          2.       DISTRIBUTION FORMULA

          Each holder of an Allowed General Fund Claim will be entitled to

receive its Pro Rata Share of the General Fund Distributable Amount.

          On the Effective Date and thereafter within forty-five (45) days

after the end of each Calendar Quarter until the Termination Date,

distributions shall be made from the General Fund to each holder of an Allowed

General Fund Claim in an amount derived in accordance with the following

formula:

                                    D=(FxA)-P
                                         -
                                         T

where

                   D =     the amount to be distributed to the holder of an
                           Allowed General Fund Claim

                   F =     the General Fund Distributable Amount as of the
                           Effective Date or as of the end of the Calendar 
                           Quarter with respect to which the calculation
                           is being made, as the case may be

                   A =     the amount of such holder's Allowed General Fund 
                           Claim

                   T =     the aggregate, as of the Effective Date or as
                           of the end of the Calendar Quarter with respect to
                           which the calculation is being made, as the case may
                           be, of (i) the Allowed amounts of all Allowed
                           General Fund Claims and (ii) the aggregate amount of
                           the Disputed General Fund Claims as Filed or as
                           capped by estimation or other procedure approved by
                           the Bankruptcy Court

                   P =     the aggregate of all distributions theretofore
                           made from the General Fund to the holder of such
                           Allowed General Fund Claim under the Plan; provided,
                           however, that if the result from such subtraction is
                           negative or zero, the distribution with respect to
                           such Claim shall equal zero.

          The Columbia Stock shall be valued, voted and distributed pursuant to

procedures proposed by TCO and approved by the Bankruptcy Court.

          3.       DELAY OF DISTRIBUTION

          Notwithstanding anything else herein contained, if at the end of any

Calendar Quarter, the aggregate of the distributions then required to be made

to the holders of Allowed General Fund Claims is less than $25 million and does

not constitute the remaining balance of the General Fund Distributable Amount,

the General Fund Trustee may in its discretion elect not to make such

distribution, in which case it shall add such distributable amounts to the

amounts to be distributed at the end of the next Calendar Quarter.

          4.       FUNDS REMAINING IN THE GENERAL FUND UPON TERMINATION

          The General Fund shall terminate on the Termination Date.  Any assets

remaining in the General Fund on the Termination Date





                                     - 64 -

in excess of the amounts that remain distributable pursuant to the Distribution

Formula or that are required to pay Post-Effective Date Costs shall be

available for the payment of such post-petition interest to Creditors as may be

Allowed by the Bankruptcy Court and any balance remaining after payment of such

interest shall be turned over by the General Fund Trustee to Reorganized TCO on

the Termination Date, net of applicable taxes, if any, with respect thereto.

          5.       TAX REQUIREMENTS OF THE GENERAL FUND

          The General Fund Trustee shall pay or cause to be paid, out of the

General Fund, any tax imposed by any governmental unit on the income generated

by the General Fund.  The General Fund Trustee shall also file, or cause to be

filed, any tax or information returns related to the General Fund and shall

satisfy any withholding obligation with respect to any distribution therefrom.

D.        REORGANIZED TCO OR THIRD PARTY AS DISBURSING AGENT FOR NON-GENERAL
          FUND CLAIMS

          Reorganized TCO, as Disbursing Agent, or such third-party Disbursing

Agent as Reorganized TCO may in its sole discretion employ, shall make all

distributions of cash required in respect of the Non-General Fund Claims under

the Plan.  Each such Disbursing Agent shall serve without bond, and each such

third-party Disbursing Agent shall be entitled to receive, from the applicable

reserve, without further Bankruptcy Court approval, reasonable compensation for

out-of-pocket expenses incurred in connection with such services, on terms

acceptable to Reorganized TCO.

E.        POST-EFFECTIVE DATE COSTS

          Each of TCO, Reorganized TCO, the Claims Supervision Committee, the

General Fund Trustee and each other Disbursing Agent, if any, shall be entitled

to be reimbursed from the General Fund for any and all Post-Effective Date

Costs incurred by it.  To obtain such reimbursement, the entity claiming

reimbursement shall submit to the General Fund Trustee, with copies to

Reorganized TCO and the Claims Supervision Committee, a written request for

such reimbursement setting forth in reasonable detail the nature and basis for

and supporting evidence of the Post-Effective Date Costs for which

reimbursement is being sought.  The General Fund Trustee shall make payment in

accordance with such request not less than ten (10) nor more than twenty (20)

days after receipt of such request unless on or before such tenth day the

General Fund Trustee, Reorganized TCO or the Claims Supervision Committee shall

object in writing (delivered by such objecting party to the other two entities)

to such reimbursement.  In the event the parties do not resolve any dispute

within thirty (30) days after submission of the request for reimbursement, the

party requesting the reimbursement may File a request for payment with the

Bankruptcy Court, which shall retain jurisdiction for the purpose of resolving

any such dispute.  Any entity having a right to reimbursement hereunder





                                     - 66 -
<PAGE>   76
shall have the right to set off any sums owed to it against funds in its

possession payable to the General Fund Trustee.

F.        DELIVERY OF DISTRIBUTIONS; UNCLAIMED DISTRIBUTIONS

          1.       DELIVERY OF DISTRIBUTIONS IN GENERAL

          Distributions to each holder of an Allowed Claim shall be made (i) at

the address set forth on the proof of Claim Filed by such holder, (ii) at the

address set forth in any written notice of address change delivered to the

relevant Disbursing Agent after the date of Filing of any related proof of

Claim, or (iii) at the address of such holder reflected in the Schedule of

Liabilities if no proof of Claim has been Filed and the relevant Disbursing

Agent has not received a written notice of a change of address.

          2.       UNCLAIMED DISTRIBUTIONS

          An Unclaimed Distribution shall be any distribution made to the

holder of an Allowed Claim pursuant to the Plan including, in the case of any

check or other instrument, the proceeds thereof, that (i) is returned to

Reorganized TCO, the General Fund Trustee or other Disbursing Agent as

undeliverable or because delivery thereof is not accepted, or (ii) in the case

of a distribution made in the form of a check or other instrument, is not

negotiated.

          Any Unclaimed Distribution shall, until such time as such Unclaimed

Distribution becomes deliverable, be paid over by the Disbursing Agent to

Reorganized TCO, which shall hold such funds and may commingle them with its

other funds; provided, however,





                                     - 67 -
<PAGE>   77
that any holder of an Allowed Claim that does not claim an Unclaimed

Distribution within the later of five (5) years after the Effective Date or two

(2) years after such Claim became an Allowed Claim shall have its Claim for

such Unclaimed Distribution discharged, shall not participate in any further

distributions under the Plan, and shall be forever barred from asserting any

such Claim against Reorganized TCO or its property.  Any cash held for

distribution on account of such holder's Claim and any accumulated income

thereon shall be property of Reorganized TCO, free of any restrictions thereon.

To the extent that such undeliverable cash and any income thereon are held by a

third-party Disbursing Agent, the third-party Disbursing Agent shall pay over

such cash and income to Reorganized TCO.  Nothing contained in the Plan shall

require any Disbursing Agent, the General Fund Trustee or Reorganized TCO to

attempt to locate any holder of an Allowed Claim other than by reviewing its

own or Reorganized TCO's records.

          Within forty-five (45) days after the end of each Calendar Quarter,

Reorganized TCO, the General Fund Trustee, or other Disbursing Agent, as

applicable, shall distribute all such previously Unclaimed Distributions that

became deliverable during the preceding Calendar Quarter.

G.        MEANS OF CASH PAYMENTS

          Cash payments made pursuant to the Plan shall be in United States

dollars by check drawn on a domestic bank selected by TCO or Reorganized TCO,

or by wire transfer from a domestic bank, at





                                     - 68 -
<PAGE>   78
the option of TCO or Reorganized TCO; provided, however, that cash payments to

foreign creditors, if any, may be made, at the option of TCO or Reorganized

TCO, in such funds and by such means as are necessary or customary in a

particular foreign jurisdiction.

H.        SETOFFS

          Reorganized TCO may set off or direct the General Fund Trustee to set

off on behalf of Reorganized TCO, against any Allowed Claim and the

distributions to be made pursuant to the Plan on account of such Claim, the

claims, rights and causes of action of any nature that TCO or Reorganized TCO

may hold against the holder of such Allowed Claim; provided, however, that

neither the failure to effect such a set off nor the allowance of any Claim

hereunder shall constitute a waiver or release by TCO or Reorganized TCO of any

such claim, right or cause of action that TCO or Reorganized TCO may possess

against such holder.

          Any amounts set off by the General Fund Trustee on behalf of

Reorganized TCO shall be paid by the General Fund Trustee to Reorganized TCO

from the General Fund in cash.

I.        EFFECTIVE DATE PAYMENTS OR DISTRIBUTIONS

          Any payment or distribution that is required under the Plan to be

arising subsequent to the Petition Date, except as expressly provided by the

Plan.

or approval by the Bankruptcy Court and free of any restrictions of the

Bankruptcy Code or Bankruptcy Rules, other than those restrictions expressly

imposed by the Plan and the Confirmation Order.  Without limiting the

Effective Date for professional fees, disbursements, expenses or related

support services without application to the Bankruptcy Court.

Reorganized TCO or corporate action to be taken by or required of either TCO or

Reorganized TCO shall be deemed to have occurred and be effective and all

actions required or contemplated in order to consummate the Plan shall be

authorized and approved in all respects without any requirement of further

action by stockholders or directors of TCO or Reorganized TCO.

C.        PRESERVATION OF RIGHTS OF ACTION

          Except as provided elsewhere in the Plan or in any contract,

instrument, release, indenture or other agreement or document entered into or

                                     - 72 -
<PAGE>   82
Avoidance Claims will be released.  Reorganized TCO or its successors may

pursue such retained claims, rights or causes of action, as appropriate, in

accordance with the best interests of Reorganized TCO.  Reorganized TCO

reserves the right to seek recovery from Customers of payments made pursuant to

the Plan which are recoverable under applicable FERC regulations or orders,

regardless of the characterization of the Claim in respect of which such

payment is made and regardless of the Class in which such Claim is classified.

D.        THE CLAIMS ESTIMATION PROCEDURES

Claims Estimation Procedures will continue to be subject thereto and each such

circumstances giving rise to the failure of such condition to be satisfied

(including any action or inaction by TCO or Columbia).  TCO's failure to

exercise any of the foregoing rights shall not be deemed a waiver of any other

rights and each such right shall be deemed an ongoing right, which may be

asserted at any time.

D.        EFFECT OF NON-OCCURRENCE OF CONDITIONS TO EFFECTIVE DATE

          Each of the conditions to the Effective Date must be satisfied or

duly waived by TCO by the 180th day after the Confirmation Date or by such

later date as is proposed by TCO and is approved by order of the Bankruptcy

Court after notice and a hearing.  If the Confirmation Order is vacated, the

Plan, including the discharge of Claims pursuant to section 1141 of the

Bankruptcy Code, and the assumptions or rejections of executory contracts or

unexpired leases pursuant to Section VII.A, shall be null and void in all

respects.  In the event the Confirmation Order is so vacated, nothing contained

in the Plan shall (i) constitute a waiver or release of any Claim by or

against, or any Interests in, TCO or Columbia, (ii) prejudice in any manner





                                     - 84 -
<PAGE>   94
the rights of TCO or Columbia or (iii) constitute an admission against TCO or

Columbia.

IX.       CONFIRMABILITY AND SEVERABILITY
          OF THE PLAN AND CRAMDOWN

A.        CONFIRMABILITY AND SEVERABILITY OF THE PLAN

          TCO and the Plan must satisfy the confirmation requirements of

section 1129 of the Bankruptcy Code.  TCO reserves the right to modify, revoke

or withdraw the Plan pursuant to Sections XII.B or XII.C.  A determination by

the Bankruptcy Court that the Plan is not confirmable pursuant to section 1129

of the Bankruptcy Code shall not limit or affect TCO's ability to modify the

Plan to satisfy the confirmation requirements of said section 1129.

B.        CRAMDOWN

          TCO requests Confirmation under section 1129(b) of the Bankruptcy

Code if any impaired Class does not accept the Plan pursuant to section 1126 of

the Bankruptcy Code.  TCO reserves the right to modify the Plan if necessary to

obtain Confirmation pursuant to section 1129(b) of the Bankruptcy Code.

X.        DISCHARGE, RELEASES, SETTLEMENT OF CLAIMS AND INJUNCTION

A.        DISCHARGE OF CLAIMS AND TERMINATION OF INTERESTS

          Except as otherwise expressly provided in the Plan or in the

Confirmation Order, the Confirmation Date operates as a discharge, pursuant to

section 1141(d) of the Bankruptcy Code, effective as of the Effective Date, of

all debts of, Claims against and Interests in TCO including any interest

accrued on Claims from the Petition Date, that arose prior to the





                                     - 85 -
<PAGE>   95

Effective Date, TCO shall be discharged from any debt that arose prior to the

Confirmation Date and from all debts of the kind specified in sections 502(g),

502(h) or 502(i) of the Bankruptcy Code, whether or not (i) a proof of Claim

based on such debt was Filed pursuant to section 501 of the Bankruptcy Code,

(ii) a Claim based on such debt is an Allowed Claim pursuant to section 502 of

the Bankruptcy Code or (iii) the holder of a Claim based on such debt has voted

to accept the Plan.

          As of the Confirmation Date, except as otherwise specifically

provided in the Plan or Confirmation Order, all entities shall be precluded

from asserting against TCO, Reorganized TCO, or their respective successors, or

the properties of any of them, any other or further Claims, debts, rights,

causes of action, liabilities or equity interests based upon any act, omission,

transaction or other activity of any kind or nature that occurred prior to the

Confirmation Date.  In accordance with the foregoing, except as provided in the

Plan or Confirmation Order, the Confirmation Order shall be a judicial

determination of discharge of all such Claims and other debts and liabilities

against TCO, pursuant to sections 524 and 1141 of the Bankruptcy Code, and such

discharge shall void any judgment obtained against TCO at any time, to the

extent that such judgment relates to a discharged Claim.

C.        REVOCATION OF THE PLAN

G.        PAYMENT AND WITHHOLDING OF TAXES

          Except as otherwise specifically provided in the Plan, (i) to the

extent that any distribution (other than a distribution from the RIA Account)

made pursuant to the Plan includes or is deemed to include the income (or an

amount equal to the income) earned on funds used to provide such distribution,

the amount of the distribution shall be reduced by the amount of income taxes

payable with respect to such income, (ii) if any of the income referred to in

clause (i) is reportable by TCO (or attributable to TCO on a consolidated tax

return), TCO shall be reimbursed out of such funds for the amount of income

such income) by (y) the highest marginal federal, state and local income tax

rates for corporations applicable to such income (as adjusted for any

deductions for state and local income taxes).
