its Subsidiaries (excluding any intercompany liabilities) from the consolidated
current assets of Midland and its Subsidiaries (excluding the Cash Balance and

determined in accordance with GAAP, and the principles, policies and practices
set forth on Schedule 2.6 which will be consistently applied for calculation of
the Target Working Capital, Closing Working Capital, and Estimated Working
Capital.

                  (b) Seller shall prepare consolidated financial statements
(the "Closing Financial Statements") of Midland and its Subsidiaries as of the
Closing Date and for the period from October 1, 2001 through the Closing Date on
the same basis and applying the same accounting principles, policies and
practices that were used in preparing the Financial Statements, including the
principles, policies and practices set forth on Schedule 2.6. Buyer shall
cooperate with Seller in providing access to all personnel and information
necessary, consistent with past practices of Midland, to prepare the Closing
Financial Statements. Seller, at its option, shall have the right to engage the
New York office of an independent nationally recognized firm of certified public
accountants (other than Ernst & Young) to review the Closing Financial
Statements, and the costs of such review shall be the responsibility of Seller.
Seller shall determine the Working Capital as of the Closing Date (the "Closing
Working Capital") based on the Closing Financial Statements. Seller shall
deliver the Closing Financial Statements and its determination (together with a
reasonably detailed explanation of its calculations) of the Closing Working
Capital to Buyer within sixty (60) days following the Closing Date unless such
time is extended by mutual agreement of the parties after Seller discusses with
Buyer the reason Seller believes an extension is necessary.

                  (c) If within twenty (20) business days following delivery of
the Closing Financial Statements and the Closing Working Capital calculation,
Buyer has not given Seller written notice of its objection to the Closing
Working Capital calculation (which notice must state the basis of Buyer's
objection), then the Closing Working Capital calculated by Seller shall be
binding and conclusive on the parties and shall be used in computing the Working
Capital Adjustment and the Closing Adjustment Amount.

                  (d) If Buyer duly gives Seller such notice of objection, Buyer
and Seller shall negotiate in good faith to resolve the issue using the best
efforts of senior, decision-making financial managers of Buyer and Seller, and
if Buyer and Seller fail to resolve the issues outstanding with respect to the
Closing Financial Statements and the calculation of the Closing Working Capital
within thirty (30) days of Seller's receipt of Buyer's objection notice, payment
of the Closing Adjustment Amount shall be made by the Buyer or the Seller, as
applicable, as to all "agreed upon" issues on said thirtieth (30th) day and
Buyer and Seller shall submit the issues remaining in dispute to the Chicago
office of Ernst & Young, certified public accountants (the "Independent
Accountants") for resolution, applying the principles, policies and practices
referred to in Section 2.6. If issues remaining in dispute are submitted to the
Independent Accountants for resolution, (i) Seller and Buyer shall promptly
furnish or cause to be furnished to the Independent Accountants such work papers
and other documents and information relating to the disputed issues as the
Independent Accountants may request and are available to that party or its
agents and shall be afforded the opportunity to present to the Independent
Accountants any material relating to the disputed issues and to discuss the
issues with the Independent Accountants; (ii) the determination by the
Independent Accountants, as set forth in a notice to be delivered to both Seller
and Buyer within sixty (60) days of the submission to the Independent
Accountants of the issues remaining in dispute, shall be final, binding and
conclusive on the parties and shall be used in the calculation of the Closing
Working Capital; and (iii) Seller and Buyer shall each bear fifty percent (50%)
of the fees and costs of the Independent Accountants for such determination.

     2.7 Payment of Purchase  Price.  The Buyer will pay the  Purchase  Price as
follows:

                  (a) Estimated Payments. At the Closing, the Buyer shall pay to
the Seller an amount (the "Estimated Purchase Price") equal to the sum of: (i)
One Hundred Thirty-Three Million Dollars ($133,000,000,), plus (ii) the
Estimated Cash Balance, plus (iii) the amount equal to the Intercompany
Receivable, minus (iv) the adjustment pursuant to Section 10.4, minus (v) the
Estimated Working Capital Adjustment.

                  (b) Closing Certificate. At the Closing, the president or
chief accounting officer of Midland shall deliver to the Buyer the Closing
Certificate in the form annexed hereto as Exhibit A, which certificate shall set
forth the Estimated Cash Balance, the Intercompany Receivable and his or her
best estimate of the Estimated Working Capital Adjustment, prepared in
accordance with Schedule 2.6.

                  (c) Closing Adjustment Amount and Payment. The "Closing
Adjustment Amount" will consist of: (i) the difference between the Cash Balance
and the Estimated Cash Balance, which if the Cash Balance is greater than the
Estimated Cash Balance would result in a payment by wire transfer of such amount
by Buyer to Seller, and if the Cash Balance is less than the Estimated Cash
Balance would result in a payment by wire transfer of such amount by Seller to
Buyer (any such wire transfer under this subsection (i) shall be netted against
the wire transfer in subsection (ii) below); and (ii) the difference between the
Working Capital Adjustment, as finally determined pursuant to Section 2.6, and
the Estimated Working Capital Adjustment. The component of the Closing
Adjustment Amount related to this subparagraph (ii) shall be paid by wire
transfer by Seller to an account specified by Buyer (if such component of the
Closing Adjustment Amount is a positive number) or wire transfer by Buyer to an
account specified by Seller (if such component of the Closing Adjustment Amount
is a negative number). All payments pursuant to this Section 2.7(c) shall be
made together with interest at the rate of five percent (5%) per annum, based on
a 365-day year, which interest shall begin accruing on the Closing Date and end
on the date the payment is made. Within three (3) business days after the
calculation of the Closing Working Capital becomes binding and conclusive on the
Parties pursuant to Section 2.6 of this Agreement, Seller or Buyer, as the case
may be, shall make the wire transfer payments provided for in this Section
2.7(c).

         2.8. Tax Treatment. The Parties acknowledge and agree that, prior to
the Closing Date, Eastern, Midland Enterprises and the Selected Subsidiaries
intend to convert or merge themselves into limited liability companies that will
be treated as "disregarded entities" under Treasury Regulation Section
301.7701-3. As a result, the Parties intend that the sale of the Membership
Interest in Midland will be treated for Federal income tax purposes as a sale by
KeySpan of the assets of Midland and the Selected Subsidiaries to the Buyer on
the Closing Date, which sale is intended to qualify under Section 1081(b) of the
Code. The Parties agree to characterize the transactions contemplated hereunder
in a manner consistent with the above treatment as a sale of assets by KeySpan
in all Tax Returns filed by each of them and not to take any position
inconsistent with such tax treatment in any Tax Returns or any other filings,
reports or statements made by them.

         7.1. Act of War or Terrorism. The Parties agree that in the event of an
Act of War or Terrorism, any physical, regulatory or statutory action occurring
after the execution of the Agreement by any foreign, federal, state or local
agency or military force, police force, or other similar force or organization
in direct or indirect response to any such Act of War or Terrorism which has a
Material Adverse Effect on (i) the ability of towboats and barges of Midland and
its Subsidiaries to physically operate on the inland waterways system of the
United States, including its channels or locks and dams, (ii) the ability to
serve docks, fleets or loading or unloading facilities of a material contracting
party of Midland and its Subsidiaries each of which represented at least five
(5%) percent of Midland and its Subsidiaries' aggregate revenues during the
prior calendar year which Material Adverse Effect, in the case of either clause
(i) or (ii), is reasonably anticipated to be of a duration in excess of six (6)
months, or is reasonably considered to be a Material Adverse Effect by a major
national bank providing financing to Buyer and Ingram in connection with the
transaction (and by banks which represent reasonable alternative sources of
financing) such that commercially-reasonable financing becomes unavailable to
Buyer and Ingram for reasons unrelated to the financial condition or
creditworthiness of Buyer and Ingram, and is a Material Adverse Effect which is
applied generally to all similarly situated financing customers of major
national banks, then either party may terminate the Agreement in accordance with
the provisions of Article X.

         7.2. Access to Books and Records. At its expense, Seller and its
authorized agents, officers and representatives shall have reasonable access
after the Closing Date to the properties, books, records, contracts, information
and documents of Midland and each of the Subsidiaries for any reasonable
business purpose, including, but not limited to, matters relating to federal or
state income, sales, use, gross receipts and property Taxes; provided, however,
that such access by Seller (a) shall be conducted during the normal business
hours of Midland and the Subsidiaries and (b) shall not unreasonably interfere
with the operations and activities of Midland or any of the Subsidiaries. The
Buyer and Midland shall cooperate, and Midland shall cause each of the
Subsidiaries to cooperate, in all reasonable respects with Seller's review of
such information, including, without limitation, retaining all such information
until Seller has notified the Buyer in writing that all tax years (including any
portion of a tax year) prior to and including the Closing Date have been closed
or for seven (7) years, whichever is longer.

         7.3.     Tax Matters.
                  -----------

                  (a)      Federal Income Taxes in General.
                           -------------------------------

                           (i) Except as otherwise provided in Section
         7.3(a)(ii), the income and other Tax items of Midland and the
         Subsidiaries for periods ending on or before the Closing Date shall be
         included in the consolidated federal income Tax Return of the
         affiliated group, within the meaning of Section 1504(a) of the Code, of
         which Eastern (or subsequent to Eastern's conversion to a limited
         liability company, KeySpan) is a member. Except as otherwise provided
         in this Section 7.3, Seller shall be responsible for and shall
         indemnify and hold Buyer, Midland and the Subsidiaries harmless from
         any federal income Taxes of Midland or the Subsidiaries (including any
         amount payable by reason of Treasury Regulation ss. 1.1502-6) not
         heretofore paid or reflected on the Closing Financial Statements, and
         shall be entitled to any reductions in such Taxes or refunds (including
         interest) not heretofore received or reflected on the Closing Financial
         Statements, for taxable periods ending on or before or, with respect to
         the consolidated federal income Tax Return of Seller's affiliated
         group, including the Closing Date. If Buyer, Midland or the
         Subsidiaries receive any such refund or become entitled to any credit
         against federal income Taxes with respect to any such period which is
         not reflected on the Closing Financial Statements, Buyer shall promptly
         pay (or cause Midland or the Subsidiaries to pay) the entire amount of
         the refund or credit (including interest) to Seller.

                           (ii) Buyer, Midland and the Subsidiaries shall be
         responsible for and shall indemnify and hold Seller and its Affiliates
         harmless from all federal income Taxes of Midland or the Subsidiaries
         for any taxable period beginning after the Closing Date and, with
         respect to prior taxable periods, for all federal income Taxes
         resulting from any action taken without Seller's written consent by
         Buyer, Midland or the Subsidiaries after the Closing (including,
         without limitation, actions taken outside the ordinary course of
         business and occurring on the Closing Date). Buyer and Seller agree to
         report all transactions not in the ordinary course of business
         occurring on the Closing Date after Buyer's purchase of the Membership
         Interest of Midland on Buyer's federal income tax return to the extent
         permitted by Treasury Regulation Section 1.1502-76(b)(i)(ii)(B). Buyer,
         Midland and the Subsidiaries shall be entitled to all refunds of such
         Taxes (including interest).

                  (b)      State Income Taxes in General.
                           -----------------------------

                           (i) For purposes of this Agreement, the term "State
         Income Tax" means any Tax, imposed by a state in the United States,
         that is based on or measured by net income. Seller shall be responsible
         for preparing and filing the State Income Tax Returns of Midland and
         the Subsidiaries for taxable periods ending on or before the Closing
         Date. Except as otherwise provided in this Section 7.3, Seller shall
         indemnify and hold Buyer, Midland and the Subsidiaries harmless from
         any State Income Taxes (including penalties and interest) of Midland or
         the Subsidiaries (including any amount payable by reason of any
         applicable provision of State Income Tax Law similar to Treasury
         Regulation ss. 1.1502-6) not heretofore paid or reflected on the
         Closing Financial Statements, and shall be entitled to any reductions
         in such Taxes or refunds (including interest) not heretofore received
         or reflected on the Closing Financial Statements, for such taxable
         periods. If Buyer, Midland or the Subsidiaries receive any such refund
         or become entitled to any credit against state income Taxes with
         respect to any such period, Buyer shall promptly pay (or cause Midland
         to pay) the entire amount, to the extent not reflected on the Closing
         Financial Statements, of such refund or credit (including interest) to
         Seller.

                           (ii) Buyer, Midland and the Subsidiaries shall be
         responsible for and shall indemnify and hold Seller and its Affiliates
         harmless from all State Income Taxes of Midland or the Subsidiaries for
         any taxable period beginning after the Closing Date and, with respect
         to prior taxable periods, for all State Income Taxes resulting from any
         action taken without Seller's written consent by Buyer, Midland or the
         Subsidiaries after the Closing (including, without limitation, actions
         taken outside the ordinary course of business and occurring on the
         Closing Date). Buyer, Midland and the Subsidiaries shall be entitled to
         all refunds of such Taxes (including interest).

                           (iii) If any of Midland and the Subsidiaries are
         required to file any State Income Tax Return for a taxable period
         covering days before and after the Closing Date, Buyer shall cause such
         Tax Return to be filed and shall be responsible for the payment of any
         Tax for such period; provided, however, that Seller shall be entitled
         to review any such Tax Return before it is filed and Buyer shall
         incorporate all reasonable comments of Seller in such Tax Returns.
         Seller shall pay to Buyer the amount, if any, by which (x) the State
         Income Tax attributable to the period through the Closing Date exceeds
         (y) the sum of the amount of such Tax paid (including payments of
         estimated Tax) on or before the Closing Date plus the amount of such
         Tax liability reflected on the Closing Financial Statements and Buyer
         shall pay to Seller the amount, if any, by which the items described in
         clause (y) exceed those described in clause (x) above. The State Income
         Tax attributable to the period through the Closing Date shall be
         determined (A) as if that period were a separate taxable year, and (B)
         except as otherwise required by Law, by using the Tax accounting
         methods and Tax elections used by Midland or such Subsidiary before the
         Closing Date. Seller shall compute the amount of such Tax attributable
         to the period through the Closing Date and shall notify Buyer of such
         amount in writing no later than 120 days after the Closing Date. Within
         45 days after the date of such notification, Seller shall pay to Buyer
         or Buyer shall pay to Seller, as appropriate, the difference between
         (I) the amount of such Tax determined by Seller as attributable to the
         portion of the period through the Closing Date, and (II) the sum of the
         amount of such Tax for the taxable period paid (including payments of
         estimated Tax) on or before the Closing Date plus the amount of such
         Tax reflected on the Closing Financial Statements, unless within 30
         days after such date, Buyer notifies Seller in writing that Buyer
         disagrees with the computation of any such amount. In that case, Seller
         and Buyer shall negotiate in good faith to resolve the issue using the
         best efforts of senior, decision-making tax managers of Buyer and
         Seller, and if Buyer and Seller fail to resolve the issues outstanding
         with respect to the State Income Tax attributable to the period through
         the Closing Date within thirty (30) days of Seller's receipt of Buyer's
         objection notice, Buyer and Seller shall submit the issue to the
         Independent Accountants for resolution using the Tax accounting methods
         and Tax elections used by Midland or such Subsidiary before the Closing
         Date. If such issue is submitted to the Independent Accountants for
         resolution, (a) Seller and Buyer shall promptly furnish or cause to be
         furnished to the Independent Accountants such work papers and other
         documents and information relating to the disputed issue as the
         Independent Accountants may request and are available to that party or
         its agents and shall be afforded the opportunity to present to the
         Independent Accountants any material relating to the disputed issues
         and to discuss the issue with the Independent Accountants; (b) the
         determination by the Independent Accountants, as set forth in a notice
         to be delivered to both Seller and Buyer within sixty (60) days of the
         submission to the Independent Accountants of the issue dispute, shall
         be final, binding and conclusive on the parties and shall be used in
         the calculation of the State Income Tax attributable to the period
         through the Closing Date; and (c) the fees and costs of the Independent
         Accountants for such determination shall be shared equally by Seller
         and Buyer. The Seller's payment to Buyer, or Buyer's payment to Seller,
         shall be due the later of (1) 45 days after Seller's notification to
         Buyer of the amount of State Income Tax attributable to the period
         through the Closing Date and (2) 10 days after Seller and Buyer agree
         to the amount payable or the Independent Accountants issue their
         determination, as the case may be. Seller and Buyer agree that the
         amounts determined under this Section 7.3(b)(iii) shall be subject to
         later adjustment based on final Tax Returns filed and accepted by the
         relevant Government Authority.

                  (c) Section 338(h)(10) Elections. If, and only if, Seller, for
reasons relating to the inability to convert or merge Midland and Selected
Subsidiaries into single-member limited liability companies, elects, at its sole
option, to allow Buyer to make an election under Section 338(h)(10) of the Code,
then the provisions of this Subsection (c) will apply.

                           (i) An election will be made by Buyer and KeySpan
         under Section 338(h)(10) of the Code ("Section 338 (h)(10) Election")
         with respect to any or all of Midland and, to the extent permissible
         under applicable Treasury Regulations, the Selected Subsidiaries.
         Seller shall prepare and file the returns for, be responsible for the
         payment of, indemnify and hold Buyer and Midland harmless from, and be
         entitled to any refund of any federal and state income Taxes, to the
         extent not reflected on the Closing Financial Statements, resulting
         from the Section 338(h)(10) Election (and any corresponding election
         under state Law). The parties acknowledge that the effect of a Section
         338(h)(10) Election will be to cause each corporation with respect to
         which such election is made to be treated as two corporations for
         federal income Tax purposes: (i) an "old" corporation, which shall be
         treated (a) as having sold all of its assets in a taxable transaction
         as of the end of the Closing Date while a member of Seller's affiliated
         group, and (b) as having completely liquidated pursuant to Sections 332
         and 337 of the Code, and (ii) a "new" corporation, which shall be
         treated as having purchased (as of the beginning of the day after the
         Closing Date) the assets deemed sold by the old corporation. The
         parties hereto further intend for each such election to be effective,
         if possible, for state (as well as federal) income Tax purposes, and
         they shall timely execute and file any documents that may be required
         under any applicable Law for such election (or any corresponding
         elections(s) under state Law) to be effective for state income Tax
         purposes.

                           (ii) Buyer and Seller shall cooperate as provided in
         this Section 7.3(c) to determine (in accordance with all applicable
         Treasury Regulations promulgated under Section 338 of the Code) the
         deemed sales prices of the assets of Midland and each Selected
         Subsidiary to which the election applies. Buyer initially shall
         determine such deemed sales prices and shall notify Seller in writing
         of the prices so determined ("Buyer's Deemed Sales Price Notice")
         within 120 days after the Closing Date. Seller shall be deemed to have
         accepted such determination unless, within 60 days after the date of
         Buyer's Deemed Sales Price Notice, Seller notifies Buyer in writing of
         (i) each proposed deemed sales price with which Seller disagrees, and
         (ii) for each such price, the amount that Seller proposes as the deemed
         sales price. If Seller provides such notice to Buyer, the parties shall
         proceed in good faith to determine mutually the deemed sales prices in
         dispute. Neither Buyer nor Seller shall take, nor shall they permit any
         affiliated corporation (including, without limitation, Midland and the
         Subsidiaries) to take, any position for income Tax purposes that is
         inconsistent with the deemed sales prices as finally determined
         hereunder; provided, however, that (i) the deemed purchase prices of
         the assets shall differ from the deemed sales prices to the extent
         necessary to reflect the inclusion in the total deemed purchase price
         of items (for example, Buyer's transaction costs) not included in the
         total deemed sales price and (ii) the amount realized upon the deemed
         sale of assets may differ from the deemed sales prices to reflect
         transaction costs that reduce the amount realized for federal income
         Tax purposes. Seller shall execute Federal Form 8023, all state forms,
         and any other form necessary to effectuate the Section 338(h)(10)
         election at least fifteen (15) days prior to the due date of the
         respective forms.

                  (d)      Cooperation.
                           -----------

                           (i) Buyer agrees to cooperate and to cause Midland
         and the Subsidiaries to cooperate with Seller to the extent reasonably
         required after the Closing Date in connection with (i) the filing,
         amendment, preparation and execution of all federal and state income
         Tax Returns with respect to any taxable period of any of Midland and
         the Subsidiaries ending on or before the Closing Date, (ii) contests
         (including, without limitation, claims or suits for refunds of Taxes)
         concerning the federal or state income Tax due for any such period or
         any period beginning before the Closing Date and (iii) audits and other
         proceedings conducted by income Tax authorities with respect to any
         such period or any period beginning before the Closing Date. Within a
         reasonable time (but not more than 10 days) after Buyer or any of
         Midland and the Subsidiaries receives official notice of any such
         contest, audit or other proceeding, Buyer shall notify Seller in
         writing of such contest, audit or other proceeding. In any case where
         any of Midland and the Subsidiaries is responsible under applicable Law
         for the defense of such contest, audit or other proceeding, Seller
         shall have the right to conduct the defense at its expense, whether
         such contest, audit or other proceeding commenced before or commences
         after the Closing. Notwithstanding Seller's obligations under the
         preceding provisions of this Section 7.3, Seller shall have no
         obligation to pay or to indemnify or hold Buyer or any of Midland and
         the Subsidiaries harmless from any income Tax imposed or assessed as a
         result of (i) the failure of Buyer to notify Seller as required by this
         paragraph, if such failure adversely affects Seller's ability to
         respond adequately in a timely manner to the notice of contest, audit
         or other proceeding, or (ii) any action taken by Buyer or any of
         Midland and the Subsidiaries with respect to any contest, audit or
         other proceeding without Seller's written consent.

                           (ii) The amount of any income Tax indemnification
         otherwise payable by Seller under this Agreement shall be reduced by
         the amount, or in the case of a Tax benefit to be realized
         subsequently, the then-present value, of any federal or state income
         Tax benefit to any Buyer Indemnified Party, Midland or the Subsidiaries
         resulting from any adjustment to or change in any Tax item relating to
         Midland or the Subsidiaries for any taxable period ending before or
         including the Closing Date, subject to Seller's reimbursement of any
         such Tax benefit paid under this Section which is disallowed by any
         relevant Governmental Authority, plus interest, from the time of
         payment hereunder until reimbursement, at the rate of five percent (5%)
         per annum. Such present value shall be based on a discount rate of ten
         (10%) percent per annum.

                           (iii) The parties agree that Seller retains all
         liability for, and shall be entitled to the federal and state income
         Tax benefit resulting from, compensation deductions relating to the
         exercise after the Closing of options to purchase common stock of
         KeySpan by employees or former employees of Midland or the
         Subsidiaries.

                            (iv) Seller agrees to make available to Buyer and
         Midland records in the custody of Seller or any member of Seller's
         affiliated group, to furnish other information and otherwise to
         cooperate to the extent reasonably required for the filing of federal
         and state income Tax Returns relating to Midland and the Subsidiaries
         for any taxable period ending after the Closing Date. However, no loss,
         credit or other item of any of Midland and the Subsidiaries may be
         carried back without Seller's written consent, which Seller may
         withhold in its absolute discretion, to a taxable period for which (i)
         any of Midland and the Subsidiaries and (ii) Seller or any corporation
         affiliated with Seller filed a consolidated, unitary or combined Tax
         Return.

                           (v) Seller agrees to cooperate with Buyer, and Buyer
         agrees to cooperate (and cause Midland to cooperate) with Seller, to
         the extent necessary in connection with the filing of any Tax Return
         relating to Buyer's acquisition of Midland. At Seller's request, Buyer
         will cause any of Midland and the Subsidiaries to make, or join with
         Seller and/or KeySpan in making, any Tax election that does not have an
         adverse effect on Buyer, Midland or any of the Subsidiaries for any
         post-acquisition Tax period.

                           (vi) Seller and Buyer each agree (A) to retain all
         books and records in its possession with respect to Tax matters
         pertinent to Midland and the Subsidiaries relating to any taxable
         period beginning before the Closing Date until the expiration of the
         statute of limitations (including any extensions thereof) of the
         respective taxable periods, and (B) to give the other reasonable
         written notice prior to transferring, destroying or discarding any such
         books and records and, if the other party so requests, shall allow the
         other party to take possession of such books and records.

                  (e) Payment of Accrued Income Taxes.  The payment of accrued
federal  income Taxes shall be handled in the manner set forth in Schedule 2.3.

                  (f) Termination of Tax-Sharing Agreement. From and after the
Closing Date, this Section 7.3 shall supersede any and all Tax-sharing or
similar agreements to which (i) any of Midland and the Subsidiaries, on the one
hand, and (ii) Seller or any of its Affiliates, on the other hand, are parties.
Neither Midland, the Subsidiaries, Seller nor any such Affiliates shall have any
obligation or right with respect to each other under any such prior agreement
after the Closing Date.

                  (g) Other Tax Returns and Taxes. Midland and the Subsidiaries
(and not the Seller) shall be responsible for preparing and filing all Tax
Returns of Midland and the Subsidiaries required to be filed after the Closing
Date except for those income Tax Returns to which Sections 7.3(a) and 7.3(b)
apply and those property and personalty Tax Returns to which Section 7.3(j)
apply ("Other Tax Returns"), and for the payment of any Taxes shown on any such
Other Tax Return. Seller shall be entitled to review such Other Tax Returns
before they are filed and Buyer shall incorporate all reasonable comments of
Seller in such Other Tax Returns. Subject to the same protections as apply in
Section 7.3(d) in the case of income Taxes, to the extent Midland and the
Subsidiaries make a payment pursuant to any such Other Tax Return relating to
such Taxes incurred prior to the Closing Date, which are not reflected on the
Closing Financial Statements, Seller shall reimburse Midland and the
Subsidiaries for the difference between the amount so paid and the amount so
reflected within sixty (60) days of receipt of a copy of such Other Tax Return
showing the amount paid which is to be compared with the amount reflected on the
Closing Financial Statements. In the event Midland or any of the Subsidiaries
receives any refund or becomes entitled to any credit against Taxes with respect
to any Taxes shown on any such Other Tax Return, Buyer shall promptly pay or
cause Midland to pay to Seller the portion of such Taxes (including interest)
borne by the Seller (either pursuant to this Section 7.3(g) or as a result of
such Taxes being reflected on the Closing Financial Statements). Notwithstanding
the foregoing, Seller and Buyer shall not be obligated to make any payments
pursuant to this Section 7.3(g) except to the extent that any single liability
exceeds $100,000 and, in the case of a payment to Buyer, unless Buyer notifies
Seller of its claim for such payment on or before the second anniversary of the
Closing Date. Except as otherwise required by Law or expressly agreed in writing
by Seller and Buyer, (i) each Other Tax Return filed after the Closing Date for
any period ending on or before or including the Closing Date shall be based on
the same accounting methods and Tax elections as used for the same type of Other
Tax Return filed most recently before the Closing Date, and (ii) no amended
Other Tax Return may be filed for a period ending on or before or including the
Closing Date.

                  (h) Relationship of Section 7.3 to Article IX. The provisions
of Article IX shall apply to all claims under this Section 7.3 except that any
conditions or limitations set forth in Article IX with respect to amount of
claims or liability shall not apply to any claim or liability to which this
Section 7.3 applies or to any breach of any obligation under this Section 7.3.
In the event of any inconsistency between provisions of Article IX and Section
7.3, this Section 7.3 shall control. Seller shall not have any liability under
this Agreement or otherwise for any Taxes of any of Midland and the Subsidiaries
except as otherwise expressly provided in this Section 7.3 with respect to Taxes
of Midland and the Subsidiaries.

                  (i) Survival. Notwithstanding any other provision of this
Agreement, except as provided in Section 7.3(g), the covenants and obligations
set forth in this Section 7.3 shall survive until, and any claim for
indemnification with respect thereto must be made prior to, the expiration of
the applicable statute of limitations with respect to the underlying Tax claim
(including any valid extensions).

                  (j) Property and Personalty Taxes. For purposes of determining
Closing Financial Statements, all property and personalty taxes applicable to
the property and personalty of Midland or the Subsidiaries for the tax period(s)
during which the Closing Date occurs shall be prorated between Buyer and Seller
with respect to each such item of property or personalty, with the Seller's
portion to be based upon the number of days within such tax period(s) prior to
the Closing Date that each such item of property or personalty was assessed for
such tax and with the Buyer's portion to be based upon the number of days on and
following the Closing Date that each such item of property or personalty was
assessed for such tax. The procedures for determining the adjustment (if any) to
the Closing Working Capital are set forth in Schedule 2.6. After taking into
account amounts of property and personalty Taxes reflected on the Closing
Financial Statements, Buyer shall reimburse Seller to the extent the amount
prorated to Buyer is less than the amount reflected on the Closing Financial
Statements, and Seller shall reimburse Buyer to the extent the amount prorated
to Buyer is greater than the amount reflected on the Closing Financial
Statements. Any such reimbursement will occur within sixty (60) days of the
payment of the relevant property and personalty Tax . In addition, in the event
Midland or any of the Subsidiaries subsequently receives any refund or becomes
entitled to any credit against Taxes with respect to refund claims previously
filed pursuant to amended Ohio Personal Property Tax returns for 2000 and 2001,
Buyer shall promptly pay or cause Midland to pay to Seller the amount of such
refunds or credit (including interest) to the extent such refund or credit was
not included in the Closing Financial Statements.

         7.4.     Employee Benefits.
                  -----------------

                  (a) The Buyer agrees to continue to provide a level of
benefits substantially similar in the aggregate to the level currently provided
under the Plans offered by Midland and the Subsidiaries as of the date hereof;
provided, however, that this shall not be construed as an agreement to maintain
any particular type of benefit or Plan for any employee or group of employees.
Notwithstanding anything to the contrary herein, Buyer shall indemnify Seller
Indemnified Parties against any and all Losses associated with claims by any
employee or retiree of Midland or any Subsidiary following the Closing Date
relating to any changes in the benefits provided by the Buyer from those
provided by KeySpan, Seller, Midland or a Subsidiary prior to Closing.

                  (b) Relationship of Section 7.4 to Article IX. The provisions
of Article IX shall apply to all claims under this Section 7.4 except that any
conditions or limitations set forth in Article IX with respect to amount of
claims or liability shall not apply to any claim or liability to which this
Section 7.4 applies, or to any breach of any obligations under this Section 7.4.
In the event of any inconsistency between provisions of Article IX and Section
7.4, this Section 7.4 shall control.

7.5.           WARN Act.
               --------

                  (a) Buyer shall be responsible for, and shall indemnify Seller
against, all expense and liability, including attorneys' fees, if applicable,
incurred under the WARN Act or any other Law requiring notice prior to
termination of employment or the payment of severance pay, wages or benefits
with respect to any employee who experiences a layoff, employment termination,
reduction in hours or other employment related loss on or after the Closing.
Seller shall be responsible for, and shall indemnify Buyer against, all expense
and liability, including attorneys' fees, if applicable, incurred under the WARN
Act or any other Law requiring notice prior to termination of employment or the
payment of severance pay, wages or benefits with respect to any employee who
experiences a layoff, employment termination, reduction in hours or other
employment related loss prior to the Closing only to the extent that any such
amounts have not been accrued as of the Closing Date and were therefore not
included in the determination of Closing Working Capital.

                  (b) The provisions of Article IX shall apply to all claims
under this Section 7.5 except that any conditions or limitations set forth in
Article IX with respect to amount of claims or liability shall not apply to any
claim or liability to which this Section 7.5 applies, or to any breach of any
obligations under this Section 7.5. In the event of any inconsistency between
provisions of Article IX and Section 7.5, this Section 7.5 shall control.

         7.6. Agreement with United Steelworkers of America Local 1652. Seller
or Midland will use reasonable best efforts to secure, prior to the Closing
Date, all signatures on the Agreement between United Steelworkers of America
Local 1652 and The Ohio River Company (Ohio Division) in the form of the
Agreement shown to Buyer.

         7.7. Historical Insurance Policies. To the extent such information
exists, Seller agrees to use reasonable efforts to locate and provide to Ingram
any summary of insurance policies covering Midland and its Subsidiaries (and
their predecessors, if any) for years 1971 up to the current in force policies
(which summary may be redacted to exclude any confidential, privileged or
proprietary information) and use reasonable efforts to locate and provide Ingram
reasonable access to all such policies for the purposes of making copies at
Buyer's expense.

     7.8  338(h)(10) Election. If Seller is not able to convert or merge Midland
and all the Selected Subsidiaries into single member limited liability companies
pursuant to Section  2.1(b) prior to the Closing Date,  Seller will allow Buyer,
at Seller's sole option to either (i) make a 338(h)(10) Election with respect to
any of  Midland  or the  Selected  Subsidiaries  that  have not  become  limited
liability companies, (ii) adjust the Purchase Price to reflect the tax detriment
to Buyer  for not being  able to make such  election,  or (iii)  allow  Buyer to
terminate in accordance with Section 10.1(h).  If Seller elects a Purchase Price
adjustment  pursuant to clause (ii), the amount of such  adjustment  shall equal
the present value (at an assumed  discount rate of ten percent per annum) of the
product of (x) an assumed  combined federal and state income tax rate of 39% and
(y) the amount of annual  depreciation or  amortization  deductions that will be
lost by Buyer as a result of Seller's failure to convert or merge Midland or any
Selected  Subsidiary  into a  single  member  limited  liability  company.  Such
adjustment  shall be  calculated,  in the first  instance,  by Buyer and Buyer's
calculation  shall be subject to Seller's  right of objection  and review in the
same manner as described in Section 7.3(b)(iii).

     7.9 Claims  Under AEGIS  Insurance  Policy.  From the date hereof until the
Closing  Date,  Seller  shall cause  Midland to  cooperate  with Buyer to review
land-based, non-marine liability claims against Midland or its Subsidiaries that
may be eligible for coverage under Midland's AEGIS claims-made  insurance policy
but have not yet been  reported to the insurer  (the  "Potential  Claims").  If,
subsequent to review,  Buyer  reasonably  determines  that any  Potential  Claim
could,  if  adversely  determined,  result  in a  liability  to  Midland  or its
Subsidiaries of $250,000 or more, then Seller shall cause Midland to report,  in
accordance  with and to the extent  permitted by applicable  policy terms,  such
Potential Claim to the insurer prior to the Closing.

     7.10 Treatment of Certain  Retirement  Plan Issues.  The Parties agree that
Schedule 7.10 sets forth the procedure for addressing  certain  retirement  plan
issues.

     7.11 Guaranties.  KeySpan will execute, upon execution of this Agreement, a
guaranty substantially in the form attached hereto as Exhibit B, and Ingram will
execute, upon execution of this Agreement,  a guaranty substantially in the form
attached hereto as Exhibit E.

         7.12     Energy Burst License.
                  --------------------

                  (a) License Grant. Subject to the provisions hereof, Seller
hereby grants to Midland a personal, nontransferable exclusive royalty-free
license to use the mark known as the Energy Burst (the "Energy Burst Mark")
according to the color scheme provided in Schedule 4.8 in the United States of
America (the "Territory") during the term of this license solely in connection
with the goods and/or services for which the Energy Burst Mark is in use by
Midland and its Subsidiaries as of the Closing Date, with the right to grant
sublicenses to Midland's Subsidiaries which sublicenses shall be effective
solely during the period the respective Subsidiary remains an Affiliate of
Midland, provided that the Subsidiaries agree in writing to be bound by the
provisions hereof, and that Midland shall be jointly and severally responsible
for the actions of such Subsidiaries. Midland shall not use the Energy Burst
Mark for any purpose except as expressly authorized herein, and shall not
sub-license, except as expressly provided herein, assign or otherwise transfer
its rights granted hereunder without the prior written consent of Seller.
Midland may also use the Energy Burst Mark in advertisements, press releases, or
promotional or sales materials containing the trade names, trademarks, or
service marks of Buyer, Ingram, or their respective Affiliates, but separate
therefrom and not in combination therewith. During the term of this license and
thereafter, without the prior written consent of Seller, (i) except for any use
by Midland and its Subsidiaries in the ordinary course of business as of the
Closing Date, Midland shall not use any Energy Burst Mark in combination with
any other trade name, trademark, or service mark, or with any prefix, suffix or
other modifying words, terms, designs or symbols, and (ii) shall not use any
other trade name, trademark or service mark that is confusingly similar to the
Energy Burst Mark. Seller reserves the right to use the Energy Burst Mark
according to other color schemes and for other goods and services, including
without limitation other color schemes now used by Seller and goods and services
now provided by Seller.

                  (b) Quality Control. Midland agrees that all services and
products provided by Midland under the Energy Burst Mark shall be of the same
quality associated therewith prior to the Closing Date. Upon Seller's reasonable
request, Midland shall provide samples of its use of the Energy Burst Mark. If
Seller reasonably determines that services or products provided by Midland using
the Energy Burst Mark do not comply with the same quality associated therewith
prior to the Closing Date, and Midland does not remedy the deficiency within a
reasonable period of time after being notified thereof, Seller may terminate
this license upon written notice to Midland.

                  (c) Ownership. The Energy Burst Mark is the sole and exclusive
property of Seller, and Midland shall now and hereafter assert no claim thereto.
All use of the Energy Burst Mark shall inure solely to Seller's benefit. Midland
shall not itself, or aid others to, contest Seller's right, title and interest
in and to the Energy Burst Mark. Midland shall use trademark notices in
association with the Energy Burst Mark as may be reasonably instructed from time
to time by Seller, allowing for reasonable depletion of existing inventories.
Seller shall have the sole right, but not the obligation, to procure and
maintain the registrations for the Energy Burst Mark and to bring actions
against infringers of the Energy Burst Mark, and Midland shall cooperate with
Seller in any such actions.

                  (d) Seller makes no representations or warranties whatsoever
about Midland's use of the Energy Burst Mark and all use of the Energy Burst
Mark by Midland is at its own risk. Notwithstanding anything to the contrary
herein, Seller shall have no liability whatsoever to Midland, Buyer, Ingram or
any of the respective Affiliates or successors arising out of or relating to
this license, Midland's use of the Energy Burst Mark, or the termination of this
license by Seller in accordance with subsection (e) below. If a third party
alleges that the intellectual property rights of such third party are being
infringed by Midland's use of the Energy Burst Mark, Seller shall have the sole
right, but not the obligation to defend such allegation and Midland shall
cooperate with Seller in any such defense. If Seller elects not to so defend, it
shall notify Midland and Midland may elect to defend such allegation at its own
expense and Seller shall cooperate with Midland in any such defense.

                  (e) License Term. Provided the license is not terminated
pursuant to the provisions of this subsection (e), the term of this license
shall begin on the Closing Date and shall extend for an initial period of five
(5) years, such period to be automatically renewed for additional five (5) year
renewal periods. This license may be terminated (i) by Seller pursuant to
subsection (b) above, (ii) by Seller if Midland discontinues its use of the
Energy Burst Mark, (iii) by mutual consent of Seller and Midland, or (iv) by
Seller if a third party alleges that the intellectual property rights of such
third party are being infringed by Midland's use of the Energy Burst Mark and
neither Seller nor Buyer are defending such allegation pursuant to subsection
(d) above. Following any termination of this license, Midland shall within
ninety (90) days discontinue all use of the Energy Burst Mark and shall within a
reasonable time destroy all advertising and promotional materials and signs that
incorporate use of the Energy Burst Mark.

made in Article III and Article IV hereof.

                  (b) Subject to paragraph (a) of this Section 9.1, all
representations and warranties and all covenants to be performed or complied
with prior to Closing, in each case contained in this Agreement, or in any

warranties which shall survive for the period of time shown: (i) the
representations and warranties contained in Section 3.1 (Ownership of Midland),

         9.2.     Indemnification by Seller.
                  --------------------------

                  (a) From and after the Closing, subject to all of the
limitations set forth in this Article IX, Seller hereby agrees to indemnify and
hold the Buyer and its directors, officers, employees, agents, Affiliates,
successors and assigns (the "Buyer Indemnified Parties") harmless from and
against any and all claims, demands, suits, proceedings, judgments, losses,
liabilities, damages, costs and expenses (including, but not limited to,
reasonable attorneys' fees and expenses) (collectively, "Losses") imposed upon
or incurred by a Buyer Indemnified Party as a result of or in connection with
any of the following:

                           (i) Any inaccuracy or breach of a representation or
         warranty made by Seller under Sections 3.1, 3.2, 4.3(a), 4.13, 4.14,
         4.17, 4.18, or 4.19 of this Agreement; or

                           (ii) The breach of, or default in the performance by
         Seller of, any covenant, agreement or obligation to be performed by
         Seller after the Closing pursuant to this Agreement or any agreement or
         instrument executed in connection herewith or pursuant hereto.

                  (b) Promptly after receipt by the Buyer of notice of an Action
or other event giving rise to a Buyer Claim with respect to which a Buyer
Indemnified Party is entitled to indemnification under this Section 9.2, the
Buyer shall notify (the "Buyer Claim Notice") Seller in writing of the
commencement of such Action or the assertion of such Buyer Claim; provided,
however, that failure to give such notice shall not affect the right to
indemnification hereunder except to the extent of actual prejudice to Seller.
Seller shall have the option, and shall notify the Buyer in writing within ten
business days after the date of the Buyer Claim Notice of its election, either:
(A) to participate (at the expense of Seller) in the defense of such Action or
Buyer Claim (in which case the defense of such Action or Buyer Claim shall be
controlled by the Buyer) or (B) to take charge of and control the defense of
such Action or Buyer Claim (at its own expense). If Seller elects to control the
defense, it will not compromise or settle the Action or Buyer Claim if (X) the
amount to be paid in settlement exceeds the Maximum Indemnity Amount or (Y) the
settlement does not include a provision releasing the Buyer Indemnified Party
from all liabilities with respect thereto. If Seller fails to notify the Buyer
of its election within the applicable response period, then Seller shall be
deemed to have elected not to control the defense of such Action or Buyer Claim.
If Seller elects to assume the defense of any Action or Buyer Claim, the Buyer
Indemnified Party shall have the right to employ separate counsel and
participate in the defense of such Action or Buyer Claim, but the fees and
expenses of such counsel shall be at the expense of the Buyer Indemnified Party
unless: (1) the named parties in such Action or Buyer Claim (including any
impleaded parties) include both a Buyer Indemnified Party and the Seller and the
Buyer Indemnified Party shall have been advised by such counsel that there may
be one or more legal defenses available to it that are different from or
additional to those available to the Seller, or (2) Buyer has reasonably
determined that Losses that may be incurred may exceed either individually, or
when aggregated with other Buyer Claims, the Maximum Indemnity Amount (in which
case, Seller shall not have the right to control the defense of such Action or
Buyer Claim on behalf of the Buyer Indemnified Party, it being understood,
however, that the Seller shall not, in connection with such Action or Buyer
Claim, be liable for the fees and expenses of more than one separate firm of
attorneys (in addition to any local counsel) and that all such fees and expenses
shall be reimbursed as they are incurred).

                  (c) If Seller does not control the defense of any Action or
Buyer Claim, then the Buyer Indemnified Party may settle such Action or Buyer
Claim only with the written consent of Seller (not to be unreasonably withheld).

         9.3.     Indemnification by Buyer.
                  ------------------------

                  (a) From and after the Closing, subject to all of the
limitations set forth in this Article IX, the Buyer hereby agrees to indemnify

successors and assigns (the "Seller Indemnified Parties") harmless from and
against any and all Losses imposed upon or incurred by a Seller Indemnified
Party as a result of or in connection with any of the following:

                         (i) Any  inaccuracy  or breach of a  representation  or
                    warranty  made by the Buyer in  Section  5.2,  5.4 of 5.9 of
                    this Agreement or in any agreement or instrument executed in
                    connection herewith or pursuant hereto;

                         (ii) The breach of or default in the performance by the
                    Buyer  of  any  covenant,  agreement  or  obligation  to  be
                    performed  by the Buyer after the  Closing  pursuant to this
                    Agreement  or  any  agreement  or  instrument   executed  in
                    connection herewith or pursuant hereto; and

                         (iii) The conduct of  Midland's  and the  Subsidiaries'
                    businesses after the Closing.

                  (b) Promptly after receipt by Seller of notice of the
commencement of an Action or other event giving rise to a Seller Claim with
respect to which a Seller Indemnified Party is entitled to indemnification, the
party receiving such notice shall notify (the "Seller Claim Notice") Buyer in
writing of the commencement of such Action or the assertion of such Seller
Claim; provided, however, that failure to give such notice shall not affect the
right to indemnification hereunder except to the extent of actual prejudice to
Buyer. Buyer shall have the option, and shall notify the Seller in writing
within ten business days after the date of the Seller Claim of its election,
either: (A) to participate (at its own expense) in the defense of the Action or
Seller Claim (in which case the defense of such Action or Seller Claim shall be
controlled by the Seller) or (B) to take charge of and control defense of such
Action or Seller Claim (at its own expense). If Buyer elects to control the
defense, it will not compromise or settle the Action or Seller Claim if (X) the
amount to be paid in settlement exceeds the Maximum Indemnity Amount, or (Y) the
settlement does not include a provision releasing the Seller Indemnified Party
from all liabilities with respect thereto. If Buyer fails to notify the Seller
of its election within the applicable response period, then Buyer shall be
deemed to have elected not to control the defense of such Action or Seller
Claim. If Buyer elects to assume the defense of any Action or Seller Claim, the
Seller Indemnified Party shall have the right to employ separate counsel and
participate in the defense of any such Action or Seller Claim, but the fees and
expenses of such counsel shall be at the expense of the Seller Indemnified Party
unless: (1) the named parties in such Action or Seller Claim (including any
impleaded parties) include both the Seller Indemnified Party and Buyer and the
Seller Indemnified Party shall have been advised by such counsel that there may
be one or more legal defenses available to it that are different from or
additional to those available to Buyer, or (2) Seller has reasonably determined
that Losses that may be incurred may exceed either individually, or when
aggregated with other Seller Claims, the Maximum Indemnity Amount (in which
case, Buyer shall not have the right to control the defense of such Action or
Seller Claim on behalf of the Seller Indemnified Party, it being understood,
however, that Buyer shall not, in connection with such Action or Seller Claim be
liable for the fees and expenses of more than one separate firm of attorneys (in
additional to any local counsel) and that such fees and expenses shall be
reimbursed as they are incurred).

                  (c) If Buyer does not control the defense of any Action or
Seller Claim, then the Seller Indemnified Party may settle such Action or Seller
Claim only with the written consent of Buyer (not to be unreasonably withheld).

         9.4. Limitation of Liability. Notwithstanding the foregoing, (i) Seller
shall not be obligated to indemnify Buyer, and Buyer shall not be obligated to
indemnify Seller, pursuant to this Article IX unless (a) the amount of all
Losses arising out of a single breach or liability exceeds fifty thousand
dollars ($50,000) (the "Minimum Claim Amount") and (b) the amount of all Losses
incurred by Buyer, or by Seller, as the case may be, exceeds one million dollars
($1,000,000) in the aggregate (the "Basket"), in which event the party seeking
indemnity may recover all Losses incurred in constituting the Basket and in
excess of the Basket, and (ii) Seller's maximum liability for Losses under
Section 9.2 and Buyer's maximum liability for Losses under Section 9.3 shall be,
in each case, fifteen million dollars ($15,000,000) (the "Maximum Indemnity
Amount").

         9.5.     Additional Indemnity Provisions.
                  --------------------------------

                  (a) The computation of the amount of any Loss subject to
indemnification under any of the provisions of this Agreement shall be (i) net
of any federal or state Tax benefit realized or the then present value (based on
a discount rate of ten percent (10%)) of any such Tax benefit to be realized by
the indemnified party (or, where a Buyer Indemnified Party is the indemnified
party, any of the Buyer Indemnified Parties, Midland or the Subsidiaries) by
reason of the facts and circumstances giving rise to the indemnification, and
(ii) increased by the amount of any federal or state Tax required to be paid by
the indemnified party on the accrual or receipt of the indemnification payment
(including any amount payable pursuant to this clause (ii)). For purposes of the
preceding sentence, the amount of any state Tax benefit or cost shall take into
account the federal Tax effect of such benefit or cost.

                  (b) The computation of the amount of any Loss subject to
indemnification under any of the provisions of this Agreement shall be net of
any insurance proceeds (net of direct collection expenses) received by the
Buyer, Midland, the Subsidiaries or any of their Affiliates on account of such
Loss. The Buyer, Midland and the Subsidiaries shall seek recovery under all
insurance policies covering any Loss to the same extent they would if such Loss
were not subject to indemnification hereunder. In the event that an insurance
recovery is made by the Buyer, Midland, the Subsidiaries or any of their
Affiliates with respect to any Loss for which any such Person has been
indemnified and paid hereunder, then a refund equal to the aggregate amount of
the recovery (net of direct collection expenses) shall be made promptly to the
Seller.

                  (c) All indemnification  payments under this Agreement shall
be deemed adjustments to the Purchase Price.

         9.6. Exclusive Remedy. From and after the Closing, the parties' sole
and exclusive recourse against each other for any Loss or claim of Losses
arising out of or relating to this Agreement or the transactions contemplated
hereby shall be expressly limited to the provisions of this Article IX. Seller
shall not have any right of contribution from Midland or the Subsidiaries with
respect to any Loss claimed by any of the Buyer Indemnified Parties.

         9.7 No Incidental, Consequential or Punitive Damages. NO BUYER
INDEMNIFIED PARTY OR SELLER INDEMNIFIED PARTY SHALL BE ENTITLED TO
INDEMNIFICATION UNDER THIS ARTICLE IX WITH RESPECT TO INCIDENTAL DAMAGES,
CONSEQUENTIAL DAMAGES, INCLUDING CONSEQUENTIAL DAMAGES CONSISTING OF BUSINESS
INTERRUPTION OR LOST PROFITS, OR PUNITIVE DAMAGES UNLESS SUCH DAMAGE RESULTS
FROM THE ACTUAL AND WILLFUL FRAUD OF THE INDEMNIFYING PARTY.

         9.8 Losses Not to Include Amounts Included in Closing Working Capital.
Notwithstanding anything to the contrary herein, no claims for indemnification
shall be made by any Buyer Indemnified Party with respect to any amounts which
are reflected as liabilities or reserves in Closing Working Capital and taken
into account in determining the Working Capital Adjustment.

         9.9 Disclosure Generally. If and to the extent any information required
to be furnished in any Schedule or Updated Schedule is contained in this
Agreement or in any other Schedule or Updated Schedule attached hereto, such
information shall be deemed to be included in all Schedules in which the
information is required to be included to the extent such disclosure is
reasonably apparent on its face, and provided such disclosure is reasonably
related to the Schedule, Updated Schedule, or portion of this Agreement in or on
which it is included. The inclusion of any information in any Schedule or
Updated Schedule attached hereto shall not be deemed to be an admission or
acknowledgement by Midland, the Subsidiaries or the Seller, in and of itself,
that such information is material to or outside the ordinary course of the
business of Midland or the Subsidiaries.

         9.10 Disclaimer of Implied Warranties. It is the explicit intent and
understanding of each party hereto that no party hereto or any of such party's
Affiliates, employees, officers, directors, representatives or agents is making
any representations or warranty whatsoever, oral or written, express or implied,
other than those set forth in this Agreement, and no Party hereto is relying on
any statement, representation or warranty, oral or written, express or implied,
made by the other Parties hereto or such other party's Affiliates,
representatives or agents, except for the representations and warranties set
forth in this Agreement. EXCEPT AS OTHERWISE SPECIFICALLY SET FORTH IN THIS
AGREEMENT, THE PARTIES EXPRESSLY DISCLAIM ALL OTHER REPRESENTATIONS AND
WARRANTIES OF ANY KIND OR NATURE EXPRESSED OR IMPLIED (INCLUDING, BUT NOT
LIMITED TO, ANY RELATING TO THE FUTURE OR HISTORICAL FINANCIAL CONDITION,
RESULTS OF OPERATIONS, ASSETS OR LIABILITIES OF MIDLAND AND THE SUBSIDIARIES).


                                    ARTICLE X
                                   TERMINATION

     10.1.  Termination.  This Agreement may be terminated and the  transactions
contemplated by this Agreement may be abandoned at any time prior to the Closing
only as follows:

                  (a)      by mutual written consent of the Buyer and Seller;

                  (b) by the Buyer or Seller if the Closing Date shall not have
occurred on or before July 2, 2002 and such date has not been extended by mutual
agreement of the parties (provided that the right to terminate this Agreement
under this Section 10.1(b) shall not be available to any party whose failure to
fulfill any obligation under this Agreement has been the cause of, or has
resulted in, the failure of the Closing Date to occur on or before such date);

                  (c) by the Buyer or Seller, if any court of competent
jurisdiction in the United States or other United States governmental body,
agency or commission shall have issued an order, decree or ruling or taken any
other action restraining, enjoining or otherwise prohibiting the transactions
contemplated hereby and such order, decree, ruling or other action shall have
become final and nonappealable;

                  (d) subject to Section  10.3  below,  by the Buyer or Seller
pursuant to Section 7.1 (Act of War or Terrorism);

                  (e) subject to Section 10.3 below, by Buyer if KeySpan fails
to receive  the SEC Order by June 27, 2002  (unless  such time is extended  with
the consent of Buyer,  which  consent  will not be unreasonably withheld) unless
Seller elects to close without such order;

                  (f) subject to Section 10.3 below, by Buyer if KeySpan fails
to receive the Tax Ruling by June 27, 2002  (unless  such time is extended  with
the consent of Buyer,  which  consent  will not be unreasonably  withheld),
unless  Seller  elects to close without such Tax Ruling; or

                  (g) by Buyer, pursuant to and in accordance with Section 7.8.

     10.2.  Effect of  Termination.  Subject  to  Section  10.3  below,  if this
Agreement  is  terminated   pursuant  to  Section  10.1  and  the   transactions
contemplated by this Agreement are not consummated,  all further  obligations of
the Parties under or pursuant to this Agreement shall terminate  without further
liability  of either  party to the other;  provided,  however,  the  obligations
contained in this Section 10.2, Section 10.3, Section 10.4, Section 6.5, Section
6.6,  and Section 11.3 of this  Agreement  shall  survive any such  termination.
Nothing  contained in this Section 10.2 shall  relieve any party from  liability
for any breach of this Agreement.

     10.3  Break-up  Fee.  In the event  Buyer  terminates  pursuant  to Section
10.1(e) or  Section  10.1(f),  so long as all other  closing  conditions  of the
Parties  set forth in Article  VIII have been  satisfied,  Seller  agrees to pay
Buyer a break-up fee equal to Buyer's  out-of-pocket  expenses in performing its
due diligence  investigation and negotiating this Agreement,  not to exceed five
hundred  thousand  dollars  ($500,000)  for a  termination  pursuant  to Section
10.1(e) or not to exceed seven hundred fifty thousand  dollars  ($750,000) for a
termination  pursuant  to Section  10.1(f).  In the event that Buyer  terminates
pursuant to Section  10.1(d),  so long as all other  closing  conditions  of the
Parties  set forth in Article  VIII have been or are  reasonably  expected to be
satisfied,  Buyer  agrees  to pay  Seller  a  break-up  fee  equal  to  Seller's
out-of-pocket expenses in negotiating this Agreement, not to exceed five hundred
thousand dollars ($500,000).

         10.4 Payment of Drydocking Expenses. In the event that the Agreement is
terminated in accordance with Section 10.1(a), the drydocking expenses as set
forth on Schedule 10.4 shall be equally shared by the Parties. In the event that
the Closing occurs, the drydocking expenses shown in item 1 of Schedule 10.4
shall be paid by Seller to Buyer at Closing by adjustment to the Estimated
Purchase Price.


                                   ARTICLE XI
                                  MISCELLANEOUS

between the parties in connection with the subject matter hereof, except as

other expenses incident to the negotiation and preparation of this Agreement and
consummation of the transactions contemplated hereby.

     11.3. Amendment.  This Agreement may not be amended except by an instrument
in writing signed by all of the Parties.

         11.4. Extension; Waiver. At any time prior to the Closing, the parties
may (a) extend the time for the performance of any of the obligations or other
acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document, certificate
or writing delivered pursuant hereto, or (c) waive compliance with any of the
covenants, agreements or conditions contained herein. Any agreement on the part
of any party to any such extension or waiver shall be valid only if set forth in
an instrument in writing signed on behalf of such party.

     11.5.  Governing  Law. This  Agreement  shall be construed and  interpreted
according to the laws of the State of Delaware  without  regard to the conflicts
of law rules thereof.

claim that any such litigation has been brought in an inconvenient forum.

         11.7. Binding Nature; Assignment. Except as expressly set forth herein,
this Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns. This Agreement and
each party's respective rights hereunder may not be assigned at any time except

party, or other than any assignment contemplated by the Eastern Merger;
provided, however, that this Agreement may be assigned by Seller to an Affiliate
prior to Closing with the consent of Buyer, which consent shall not be
unreasonably withheld, and after the Closing without the consent of Buyer so
long as the KeySpan guaranty is in place.
