                                    RECITALS

          WHEREAS, the parties desire to make certain amendments to the Employee
Agreement and the Sale Agreement to the extent and in the manner hereinafter set
forth; and

          WHEREAS, Section 10.1 of the Sale Agreement incorporates the terms and
provisions of the Employee Agreement, and Section 13.12 of the Sale Agreement
permits the amendment of the Sale Agreement only by an instrument in writing
executed by Seller and Buyer.

          NOW, THEREFORE, in consideration of the premises and agreements
contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, and intending to be legally bound
hereby, the parties hereto hereby agree as follows:

     1. DEFINED TERMS. All capitalized terms used, but not defined, in this
Agreement shall have the meanings ascribed or given to them under the terms of
the Employee Agreement or the Sale Agreement.

     2. AMENDMENTS TO THE EMPLOYEE AGREEMENT. The parties hereby agree to the
following amendments to the Employee Agreement:

          (A) SECTION 1.1. Section 1.1 of the Employee Agreement shall be
amended to add the following definition:

          "Unfunded ABO under Seller's Pension Plan" shall mean the unfunded
accumulated benefit obligation under Seller's Pension Plan, determined by
Seller's actuaries in accordance with Statement of Financial Accounting Standard
No. 87 as of the last day of the month preceding the Closing Date, based on (1)
the most recently available January 1st census data projected to such last day
of the month preceding the Closing Date, (2) asset values determined as of such
last day of the month preceding the Closing Date, and (3) the discount rate,
determined using the Citigroup Pension Discount Curve, determined as of the end
of the month preceding the Closing Date, as posted on the Society of Actuaries'
website; provided, however, that such determination by Seller's actuaries shall
be subject to confirmation of such calculation by Buyer's actuaries."
<PAGE>
          (B) SECTION 1.2. Section 1.2 of the Employee Agreement shall be
amended to delete the reference to "Buyer's Pension Plan," which was defined in
Section 3.1 of the Employee Agreement.

          (C) SECTION 2.6. Section 2.6 of the Employee Agreement shall be
amended to delete the final sentence of Section 2.6.

          (D) SECTION 3.1. Section 3.1 of the Employee Agreement shall be
amended and restated in its entirety to read as follows:

          SECTION 3.1 PENSION PLANS. Seller has no defined benefit plan that
covers the Employees and that is intended to be a qualified plan other than the
Employees' Retirement Plan of Southern Union Company Pennsylvania Division
("Seller's Pension Plan"). No later than the Closing Date, Seller shall
contribute, in cash, to Seller's Pension Plan an amount equal to the Unfunded
ABO under Seller's Pension Plan, plus interest, at the discount rate as of the
end of the month preceding the Closing Date used to determine the Unfunded ABO
under Seller's Pension Plan, for the period beginning on the last day of the
month preceding the Closing Date until the Closing Date. Effective as of the
Closing Date, Buyer shall assume sponsorship of, and all assets (held in trust),
liabilities and obligations under, Seller's Pension Plan, including liability
for any contributions due after the Closing Date. Seller acknowledges and
confirms to Buyer that, as a result of Seller's contribution of an amount equal
to the Unfunded ABO under Seller's Pension Plan no later than the Closing Date,
no further contributions with respect to Seller's Pension Plan will be required
for the 2005 plan year. Seller also acknowledges and confirms to Buyer that
Seller has made, on a timely basis, the first two required quarterly
contributions with respect to Seller's Pension Plan for the 2006 plan year. On
the Closing Date, or as soon as administratively feasible following the Closing
Date, but in no event later than five business days after the Closing Date, the
assets held in trust under Seller's Pension Plan shall be transferred, in
accordance with the letter agreement between the parties relating to such
transfer of assets, to a trust designated by Buyer to fund Seller's Pension Plan
following the Closing Date. Seller and Buyer shall take all action necessary and
appropriate to establish Buyer, effective as of the Closing Date, as successor
to Seller as to all rights, assets (held in trust), duties, liabilities and
obligations under or with respect to Seller's Pension Plan. Buyer shall be
responsible for the preparation and filing of any annual reports relating to
plan years that include the Closing Date; provided, however, that Seller shall
furnish Buyer with such information concerning Seller's Pension Plan as is
necessary to prepare such forms, specifically including an executed Schedule B
attachment for the 2006 Form 5500, which Buyer may choose to use in connection
with such filing. Seller shall be responsible for the preparation and filing of
any annual reports relating to all plan years ending prior to the Closing Date.

     3. AMENDMENTS TO THE SALE AGREEMENT. The parties hereby agree to the
following amendments to the Sale Agreement:

          (A) SECTION 1.1. Section 1.1 of the Sale Agreement shall be amended by
(i) amending clause (i) of the definition "Excluded Assets" by inserting at the
beginning

                                       2
<PAGE>
thereof the phrase "Except as otherwise provided in Section 6.9," and (ii)
deleting the figure "$67,500,000" appearing in the definition "Working Capital
Target" and substituting therefor the figure "$68,100,000".

          (B) SECTION 2.2(C). Section 2.2(c) shall be amended to read in its
entirety: "(c) obligations and liabilities of Buyer and its Affiliates under the
Employee Agreement and all liabilities or obligations relating to the matter set
forth on Schedule 2.2(c).

          (C) SECTION 2.3. Section 2.3 shall be amended by deleting from clause
(e) thereof the phrase ", and all liabilities or obligations relating to the
matter set forth on Schedule 2.3(b)".

          (D) SCHEDULE 2.3(B). Schedule 2.3(b) shall be redesignated as Schedule
2.2(c).

          (E) SECTION 5.13. Section 5.13 of the Sale Agreement shall be amended
and restated in its entirety to read as follows:

          SECTION 5.13 EMPLOYEE BENEFIT MATTERS.

          (a) Schedule 5.13 lists (i) each "Employee Benefit Plan," as such term
is defined in Section 3(3) of ERISA, that is covered by any provision of ERISA
and that is maintained by Seller for the benefit of the Employees and each other
material fringe benefit plan, policy or arrangement currently maintained by
Seller for the benefit of the Employees that provides for pension, deferred
compensation, bonuses, severance, employee insurance coverage or similar
employee benefits (collectively, the "Employee Plans"); and (ii) each collective
bargaining, union or other employee association agreement, employment agreement
and other material agreement, policy or arrangement maintained by Seller for the
Employees. Seller has made available to Buyer copies of all documents setting
forth the terms of such plans, policies, agreements and arrangements, or
summaries of any such plans, policies, agreements and arrangements not otherwise
in writing.

          (b) Seller's Pension Plan and Seller's 401(k) Plan are the only
Employee Plans that are intended to be qualified under Section 401(a) of the
IRC.

          (c) The Subsidiary does not employ any Employees or any other
individuals and does not currently maintain any Employee Plan.

          (d) To the Seller's Knowledge, each Employee Benefit Plan maintained
by Seller for the benefit of the Employees has been established and administered
in all material respects in accordance with its terms and the applicable
provisions of ERISA and the IRC.

          (e) Seller has delivered to Buyer true, correct and complete copies of
(i) all current documents governing Seller's Pension Plan, and all amendments
thereto, and to the extent that Seller has possession of same, any predecessor
or prior versions of Seller's Pension Plan, (ii) all reports filed on or after
November 4, 1999 by Seller, a

                                       3
<PAGE>
Benefits Affiliate or a Plan official with the United States Department of
Labor, the IRS or any other federal or state regulatory agency with respect to
Seller's Pension Plan, (iii) all summary plan descriptions, notices and other
reporting and disclosure material furnished to participants in Seller's Pension
Plan, (iv) all actuarial, accounting and financial reports, if any, prepared
with respect to Seller's Pension Plan on or after November 4, 1999, (v) all
current manuals, procedures, guidelines, forms, files and data pertaining to the
administration of Seller's Pension Plan, (vi) all post-November 4, 1999 minutes,
resolutions, determinations of any committee, person or other entity serving as
plan administrator or otherwise acting in a fiduciary capacity with respect to
the administration or management of Seller's Pension Plan, and (vii) all
currently effective IRS ruling or determination letters on Seller's Pension
Plan. The term "Benefits Affiliate" shall include (i) any corporation which is a
member of a controlled group of corporations (as defined in section 414(b) of
the IRC) which includes Seller, (ii) any trade or business (whether or not
incorporated) which is under common control (as defined in section 414(c) of
IRC) with Seller, (iii) any organization (whether or not incorporated) which is
a member of an affiliated service group (as defined in section 414(m) of the
IRC) which includes Seller and (iv) any other entity required to be aggregated
with Seller pursuant to the regulations issued under section 414(o) of the IRC.

          (f) Seller's Pension Plan and provisions thereof, any trusts created
thereby and the operation of Seller's Pension Plan are (and at all times have
been) in compliance in all material respects with the terms of Seller's Pension
Plan and conform (and at all times have been in compliance with and conformed)
in all material respects to the applicable provisions of the IRC, ERISA and all
other applicable statutes and governmental rules and regulations.

          (g) Seller's Pension Plan has been determined by the IRS to be
qualified in form under section 401(a) of the IRC and exempt from tax under
section 501(a) of the IRC, and each such determination remains in effect and has
not been revoked. To the Seller's Knowledge, nothing has occurred with respect
to the design or operation of Seller's Pension Plan that could cause the loss of
such qualification or exemption or the imposition of any liability, lien,
penalty or tax under ERISA or the IRC. Any amendment to Seller's Pension Plan to
comply with current law and regulations that is required to be made on or before
the Closing Date has been timely made.

          (h) With respect to Seller's Pension Plan, there has occurred no
non-exempt "prohibited transaction" (within the meaning of section 4975 of the
IRC or section 406 of ERISA) or breach of any fiduciary duty described in
section 404 of ERISA that could result in any liability, direct or indirect, for
Seller or a Benefits Affiliate or any shareholder, officer, director or employee
of Seller or a Benefits Affiliate. Seller and its Benefits Affiliates have paid
all amounts that Seller and its Benefits Affiliates are required to pay as
contributions to Seller's Pension Plan as of the Closing Date.

          (i) Seller and its Benefits Affiliates have not incurred any liability
for any excise, income or other taxes or penalties with respect to Seller's
Pension Plan, and to the Seller's Knowledge, no event has occurred and no
circumstance exists or has existed that could give rise to any such liability.
There are no pending or, to the Knowledge of Seller,

                                       4
<PAGE>
threatened claims by or on behalf of Seller's Pension Plan, or by or on behalf
of any participants in or beneficiaries of Seller's Pension Plan or other
persons, alleging any breach of fiduciary duty on the part of Seller or any
Benefits Affiliate or any of their officers, directors or employees under ERISA
or any applicable law, or except as set forth in Schedule 5.13(i), claiming
benefit payments other than those made in the ordinary operation of Seller's
Pension Plan, nor is there any basis for any such claim. Seller's Pension Plan
is not presently under audit or examination (nor has notice been received of a
potential audit or examination) by the IRS, the Department of Labor or any other
governmental entity, and no matters are pending with respect to Seller's Pension
Plan under any IRS program. Seller has delivered to Buyer any memorandum
pertaining to self-correction of any operational defects with regard to Seller's
Pension Plan.

          (j) Neither Seller nor any Benefits Affiliate has made any plan or
commitment, whether or not legally binding, to modify or change the terms of
Seller's Pension Plan. Seller's Pension Plan may be amended or terminated
without penalty by Buyer or its Benefits Affiliates at any time on or after the
Closing, subject to any requirements under the collective bargaining agreements
referred to in Section 2.2 of the Employee Agreement and subject to applicable
legal requirements, specifically including the anti-cutback requirements under
section 411(d)(6) of the IRC.

          (k) The only representations and warranties given in respect of
employee benefit matters are those contained in this Section 5.13 and none of
the other representations and warranties contained in this Agreement shall be
deemed to constitute, directly or indirectly, a representation or warranty in
respect of employee benefit matters.

          (F) SCHEDULE 5.13. The attached revised Schedule 5.13 to the Sale
Agreement is hereby substituted for the original Schedule 5.13 to the Sale
Agreement. The original Schedule 5.13 incorrectly listed the Southern Union
Company Severance Pay Plan as the Southern Union Company Severance Plan, and it
failed to list collective bargaining agreements. The Schedules to the Sale
Agreement are further amended by the addition of new Schedule 5.13(i) in the
form attached hereto.

          (G) SECTION 6.9. Section 6.9 of the Sale Agreement shall be amended in
its entirety to read as follows:

          SECTION 6.9. INSURANCE.

          (a) At Buyer's request and expense, Seller agrees to use commercially
reasonable efforts to assert and diligently pursue all rights to insurance
coverage under the Policies (other than with respect to Workman's Compensation
and punitive damage policies) and any other past insurance policies of Seller
relating to the Business or the Assets (such insurance policies shall
collectively be referred to herein as the "Insurance Policies") with respect to
claims arising from the Business or Assets relating to Assumed Liabilities,
whether asserted prior to or after the Closing Date. Seller shall advise Buyer
of material developments in respect of such claims and shall not settle or
otherwise resolve any claims so asserted without the prior consent of Buyer,
such consent not to be unreasonably withheld, provided, however, that Seller may
settle claims or policies

                                       5
<PAGE>
relating to the Business or the Assets relating to Assumed Liabilities (other
than claims under or policies constituting AEGIS Policies, as defined in clause
(b) below) without the prior consent of Buyer in connection with a settlement of
policies of Seller relating to the Excluded Assets or Retained Liabilities,
including Seller's businesses other than the Business, subject to remittance by
Seller to Buyer of an allocable portion of the proceeds of such settlement (net
of Seller's costs and expenses), as determined by the insurers with whom such
claims are settled (or in the absence of such allocation by the insurers, by
Seller in proportion to the claims attributable to the Assumed Liabilities to
the totality of Seller's claims to such insurers). Seller shall remit to Buyer
all insurance proceeds obtained after Closing in respect of claims arising from
the Business or Assets relating to Assumed Liabilities. Seller agrees to use
commercially reasonable efforts to negotiate with each of its insurance
companies in order to provide Buyer the benefit of the coverage under the
policies for all claims arising prior to the Closing from the Business or Assets
related to the Assumed Liabilities whether asserted before or after the Closing
Date and to cooperate with Buyer with any efforts to obtain "tail" coverage, at
Buyer's sole cost, with respect to any "claims made policies." Notwithstanding
anything herein to the contrary, any recovery of insurance proceeds by Buyer
shall be net of all Seller's cost and expenses. Seller shall give access to
Buyer to all of the non-privileged information relating to these matters and
shall consult with Buyer on the progress thereof from time to time. Nothing set
forth in this Section 6.9 shall limit Seller's right to assert claims under any
Insurance Policies in respect of Retained Liabilities.

                  (b) Upon Buyer's request, except as otherwise provided herein,
to the maximum extent permitted by the terms of the Insurance Policies listed on
Part I of Schedule 6.9(b) (the "AEGIS Policies"), Seller shall transfer, assign,
convey and deliver to Buyer all Seller's rights, if any, under the AEGIS
Policies solely to the extent of coverage arising from the Business or Assets
relating to Assumed Liabilities. Anything in this Agreement to the contrary
notwithstanding, this Section 6.9(b) shall not be construed to operate as an
assignment of any rights under any such AEGIS Policy if an attempted assignment
thereof, without the Consent of a third party thereto, would render such AEGIS
Policy null and void or otherwise adversely affect the aggregate amount or terms
of coverage available thereunder. In addition, Seller shall use commercially
reasonable efforts to cause the insurer in respect of Policy No. X0012A1A06
(constituting one of the AEGIS Policies) to issue an endorsement substantially
in the form attached hereto as Part II of Schedule 6.9(b), and Buyer
acknowledges that issuance of such endorsement shall satisfy Seller's
obligations under the fourth sentence of Section 6.9(a) with respect to such
AEGIS Policy. In the event that the insurer under the AEGIS Policies shall fail
to pay a claim arising from the Business or Assets relating to the Assumed
Liabilities, Seller agrees that, at Buyer's request, Seller shall use
commercially reasonable efforts to pursue such claim against the insurer,
including through litigation, at the sole expense of Buyer. Seller shall advise
Buyer of material developments in respect of such claims and shall not settle or
otherwise resolve any such claim without the prior consent of Buyer, such
consent not to be unreasonably withheld. Buyer hereby acknowledges that Seller
has asserted, and there are currently outstanding, claims under certain of the

                                       6
<PAGE>
AEGIS Policies in an aggregate amount equal to $2.3 million in respect of
environmental costs and expenses incurred by Seller prior to the Closing
("Seller's Environmental Claim"). Except as provided in this Section 6.9(b),
Seller shall keep the AEGIS Policies in full force and effect, take no action
with respect to the AEGIS Policies to terminate or reduce the coverage available
thereunder and make all required payments thereunder. Notwithstanding anything
herein to the contrary, Seller shall not be obligated, in respect of any policy
period after the Closing Date, to continue to purchase insurance coverage from
AEGIS. To the extent that the AEGIS Policies provide coverage for the benefit of
both Buyer and Seller, both parties reserve the right to submit claims under
those policies and to use commercially reasonably efforts to prosecute such
claims provided the resolution of the claim does not reduce the amount of
coverage available to the other party by more than the amount of proceeds
recovered by such party.

          (c) Except as provided in this Section 6.9(c), after the Closing,
Buyer shall be responsible for, and neither Seller nor any of its Affiliates
shall have any responsibility for, the payment of any deductible amounts,
underlying limits or excess or excluded amounts attributable to the Insurance
Policies, provided that Seller shall retain such responsibility for claims that
relate to the Retained Liabilities and Seller's Environmental Claim. Buyer
acknowledges that certain of the Insurance Policies may require Seller or any of
its Affiliates to provide an indemnity to the insurer for deductible amounts and
to provide collateral to secure such indemnity obligations. Buyer shall enter
into an indemnification agreement in form mutually acceptable to Buyer and
Seller wherein Buyer agrees to indemnify and hold harmless Seller or any of its
Affiliates (as applicable) for any and all of the costs of maintaining such
collateral and for any charges made against such collateral or indemnification
payments or for any expenses reasonably incurred by Seller in connection with
claims arising or alleged to arise from the operations of the Business under or
with respect to such Insurance Policies from and after the Closing Date. If
there is a retrospective adjustment in respect of any of the Insurance Policies,
Buyer shall pay to Seller its allocable portion of such adjustment.

          (d) Seller makes no representation or warranty with respect to the
applicability, validity or adequacy of any Insurance Policies, and Seller shall
not be responsible to Buyer or any of its Affiliates for the failure of any
insurer to pay under such Insurance Policy.

          (e) Nothing in this Agreement is intended to provide or shall be
construed as providing a benefit or release to any insurer or claims service
organization of any obligation under any Insurance Policy. Nothing herein shall
be construed as creating or permitting any insurer or claims service
organization the right of subrogation against Seller or Buyer or any of their
Affiliates in respect of payments made by one to the other under any Insurance
Policy.

          (H) SCHEDULE 6.9. The Sale Agreement shall be amended by adding
thereto new Schedules 6.9(a) and 6.9(b) in the forms attached hereto.

          (I) SECTION 6.13. Section 6.13 of the Sale Agreement shall be amended
by amending the second sentence thereof to read in its entirety as follows:
"Seller shall deliver the Audited Financials to Buyer not later than five (5)
Business Days after the Closing."

                                       7
<PAGE>
          (J) SECTION 6.15. The Sale Agreement shall be amended by inserting
therein a new Section 6.15 to read in its entirety as follows:

          SECTION 6.15. FURTHER ASSURANCES; COOPERATION. From time to time after
the Closing Date, without further consideration, Seller will execute and deliver
such documents to Buyer as Buyer may reasonably request in order to more
effectively consummate the sale and purchase of the Assets or to more
effectively vest in Buyer good and indefeasible title to the Assets subject to
the Permitted Encumbrances. Seller shall cooperate with Buyer, at Buyer's
expense, in Buyer's efforts to cure or remove any Permitted Encumbrances that
Buyer reasonably deems objectionable. From time to time after the Closing Date,
without further consideration, Buyer will execute and deliver such documents to
Seller as Seller may reasonably request in order to evidence Buyer's assumption
of the Assumed Liabilities.

          (K) SECTION 12.3. The first sentence of Section 12.3(b) shall be
amended in its entirety to read as follows:

Except as provided below, the representations and warranties of Seller set forth
in this Agreement shall survive the Closing until the first anniversary of the
Closing Date; provided, however, that (i) the representations and warranties set
forth in Section 5.2 (Authority Relative to this Agreement and Binding Effect),
Section 5.5 (Title to Assets; Encumbrances), and Section 5.17 (Brokers) shall
survive indefinitely, (ii) representations and warranties set forth in Section
5.9 (Taxes) shall survive for a period equal to the applicable statute of
limitations for the taxable year for each Tax, and (iii) representations and
warranties set forth in clauses (e) through (j) of Section 5.13 shall survive
until the second anniversary of the Closing Date.

          (L) SECTION 12.4. Section 12.4 shall be amended by adding at the end
thereof the following sentence: "Buyer shall have no liability for any claim or
Loss to the extent of insurance proceeds actually received by Seller in respect
thereof under insurance maintained by or for the benefit of Seller or any
Affiliate of Seller."

     4. NO OTHER MODIFICATION. This First Amendment Agreement amends the Sale
Agreement and the Employee Agreement only to the extent and in the manner herein
set forth. In all other respects, the terms and conditions of the Sale Agreement
and the Employee Agreement shall remain in full force and effect.

     5. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which will be deemed an original, but all of which
together will constitute one and the same instrument.
