         Section 3.1     Purchase Price. The aggregate purchase price for the
Company Equity Interests shall be $94,300,000, as adjusted pursuant to Section
3.2 ("Purchase Price").

         Section 3.2     Purchase Price Adjustment.

                (a)      Working Capital Adjustment. The Purchase Price is based
on the understanding that on the Closing Date, the Company has Working Capital
of $-0- (the "Target Working Capital Amount"), and Seller agrees to use
commercially reasonable efforts to cause the Company's Working Capital to be
zero on the Closing Date. If the Company's Working Capital is not equal to the
Target Working Capital Amount, the Purchase Price shall be adjusted upwards by
the amount by which the Company's Working Capital exceeds the Target Working
Capital Amount or downwards by the amount by which the Target Working Capital
Amount exceeds the Company's Working Capital.

                (b)      Adjustment Procedures.

                         (i)      At least five Business Days prior to the
         anticipated Closing Date, Seller, with the assistance and participation
         of, and in consultation with, Purchaser, shall prepare and provide
         Purchaser with an estimate of the Company's Working Capital as of the
         Closing Date, and if such estimate is above or below the Target Working
         Capital Amount, the Purchase Price payable on the Closing Date shall be
         adjusted upward or downward, as the case may, be, as provided in
         Section 3.2(a).

                         (ii)     If, following the Closing, Purchaser believes
         that an adjustment to the Purchase Price is required in addition to the
         adjustment, if any, provided in Section 3.2(b)(i), Purchaser will cause
         to be prepared and delivered to Seller no later than 90 days after the
         Closing Date an audited balance sheet of the Company, as at the Closing
         Date, which balance sheet shall present fairly, in conformity with
         GAAP, the assets and liabilities of the Company as at the close of
         business on the Closing Date and shall set forth the Company's Working
         Capital. Subject to the dispute procedures set forth in Section 3.2(c),
         if such balance sheet shows that the actual Working Capital of the
         Company as at the Closing Date is different than that used for
         determining the adjusted Purchase Price payable on the Closing Date,
         the Purchase Price shall be adjusted downward or upward, as the case
         may be, to reflect the actual Working Capital of the Company as at the
         Closing Date, and the Purchaser or


                                       10

<PAGE>

         Seller, as the case may be, shall, as promptly as possible, pay or
         refund, as the case may be, the amount by which the Purchase Price as
         estimated pursuant to Section 3.2(a) was less than or exceeded the
         Purchase Price as finally determined pursuant to this Section 3.2(b).
         The cost of any audit performed for purposes of this Section 3.2(b)
         shall be shared equally by Purchaser and Seller.

                (c)      Dispute Procedures. During the 30-day period following
Seller's receipt of the audited balance sheet for the Company delivered pursuant
to Section 3.2(b), Seller and its independent auditors will be permitted to
review the working papers of the auditors relating to the audited balance sheet.
The audited balance sheet shall become final and binding upon the Parties on the
thirtieth day following receipt thereof by Seller unless Seller gives Purchaser
written notice of its disagreement therewith prior to such date. Any notice of
disagreement shall specify in reasonable detail the nature of any disagreement
so asserted. If a notice of disagreement is received by Purchaser in a timely
manner, then the audited balance sheet (as revised in accordance with clauses
(i) or (ii) below) shall become final and binding upon the Parties on the
earlier of (i) the date the Parties resolve in writing any differences they have
with respect to any matter specified in the notice of disagreement or (ii) the
date any disputed matters are finally resolved in writing by the arbitrator
referred to below. During the 30-day period following the delivery of a notice
of disagreement, or such longer period as may be agreed upon by Seller and
Purchaser, Seller and Purchaser shall seek in good faith to resolve in writing
any differences that they may have with respect to any matter specified in the
notice of disagreement. At the end of such 30-day period, or such longer period
as may have been agreed upon, Seller and Purchaser shall submit to an arbitrator
for review and resolution any and all matters arising under this Section 3.2(c)
which remain in dispute. The arbitrator shall be a nationally recognized
independent public accounting firm as shall be agreed upon by the Parties in
writing. The arbitrator shall render a decision resolving the matters submitted
to the arbitrator within 30 days following submission thereto. The cost of any
arbitration (including the fees of the arbitrator) pursuant to this Section
3.2(c) shall be borne 50% by Purchaser and 50% by Seller. The fees and
disbursements of Seller's independent auditors incurred in connection with their
review of the audited balance sheet shall be borne by Seller.

transactions contemplated herein and therein. Except as set forth in Section
4.14 of Seller's Disclosure Schedule, as of the date hereof, there is no order,
judgment, injunction or decree of any Governmental Authority outstanding against
the Company or against Seller (as it pertains to the Company or the Transmission
Business), that, individually or in the aggregate, would have any effect

                                       17

within the six years prior to the Closing Date sponsored, maintained or had any
obligation to contribute to any employee pension benefit plan within the meaning
of Section 3(3) of ERISA.

         Section 4.17.   Insurance.

                (a)      Section 4.17 of Seller's Disclosure Schedule lists of
all Transmission Business Insurance Policies and all such policies are in full
force and effect on the date hereof.

                (b)      All premiums payable under such Transmission Business
Insurance Policies have been paid in a timely manner and each of the Company and

necessary and appropriate actions to preserve any and all rights to
indemnification in their favor pursuant to clause (ii) of Section 12.2 of the
purchase and sale agreement dated July 15, 1999 between Ocean Energy, Inc. and

or materially impair or delay the ability of Purchaser to perform its
obligations under this Agreement or the other Operative Documents or to
consummate the transactions contemplated hereby or thereby.

         Section 5.5.    Brokers. No investment banker, financial advisor,

                (i)      The Company and Seller have given and, during the

         Seller and their agents, including legal representatives and
         accountants, as such relate to the Company Assets and the Transmission
         Business, and will furnish or shall cause to be furnished, at no cost
         to Purchaser other than reasonable out-of-pocket expenses and the cost
         of copying or duplication, all information and documents relating to
         the Transmission Business as Purchaser may reasonably request, and
         permit Purchaser to contact and meet with the employees of Seller
         involved in the Transmission Business at such place or places and at
         such times as reasonably designated by Purchaser, provided that no such
         investigation shall unreasonably interfere with the Transmission
         Business, or relationships with employees or customers of Seller or
         customers of the Company. During the Interim Period, Seller shall
         permit Purchaser to make copies of information relating to the
         Transmission Business contained in the books, files and records of
         Seller and the Company. Purchaser will cause all information regarding
         Seller, the Company or the Transmission Business obtained or acquired
         by Purchaser or Purchaser's representatives, employees, consultants,
         independent contractors, attorneys and financing sources and other
         advisors (the "Purchaser Parties") pursuant to this Agreement to be
         used and maintained by the Purchaser Parties in accordance with the
         terms of the confidentiality agreement dated February 27, 2003, by and
         between McDonald Investments Inc. (as agent for Seller) and Purchaser
         (the "Confidentiality Agreement"). Notwithstanding the foregoing
         provisions of this Section 6.1(b), (1) to the extent necessary in order
         to obtain the Purchaser Required Governmental Consents, Purchaser may
         disclose such information to the appropriate Governmental Authorities
         provided Purchaser makes commercially reasonable efforts to ensure that
         the information that is so disclosed will be


                                       23

<PAGE>

         accorded confidential treatment by the Governmental Authority; (2)
         Seller shall not be required to disclose information to the extent that
         the disclosure thereof is prohibited under confidentiality agreements
         currently in effect on the date hereof, and (3) Purchaser shall be
         permitted to disclose information to the extent required by applicable
         Legal Requirements or stock exchange regulations or to the extent
         requested by its (or its designee's) lenders.

                (ii)     Seller shall have the right to have a representative
         present at all times of any inspections, interviews, and examinations
         conducted at or on the offices or other facilities or properties of
         Seller or the Company. Purchaser shall have no right of access to, and
         Seller shall have no obligation to provide to Purchaser, (1) bids
         received from others in connection with the transactions contemplated
         by this Agreement and information and analysis (including financial
         analysis) relating to such bids, or (2) any information the disclosure
         of which would jeopardize any privilege available to the Company,
         Seller or any of their Affiliates relating to such information or would
         cause Seller to breach a confidentiality obligation. Purchaser agrees
         that if Purchaser or its authorized representatives receive, or if the
         information (whether in electronic mail format, on computer hard drives
         or otherwise) held by the Company as of the Closing includes
         information that relates to the business operations or other strategic
         matters of Seller, or any of its Affiliates (other than the Company),
         such information shall be held in confidence on the terms and subject
         to the conditions contained in the Confidentiality Agreement, but the
         term of the restriction on the disclosure and use of such information
         shall continue in effect as to such information for a period of two
         years from the Closing. Purchaser further agrees that if Seller or the
         Company inadvertently furnishes to Purchaser copies of or access to
         information that is subject to clause (2) of the second preceding
         sentence, Purchaser will, upon Seller's request, promptly return same
         to Seller and Purchaser will destroy any and all extracts therefrom or
         notes pertaining thereto (whether in electronic or other format).

                (iii)    Purchaser agrees that Seller may retain (1) a copy of
         all materials included in the Data Room, together with a copy of all
         documents referred to in such materials, (2) copies of all books and
         records prepared by Seller or its Affiliates in connection with the
         transactions contemplated by this Agreement, including bids received
         from others and information relating to such bids, (3) copies of any
         books and records which may be relevant in connection with the
         assertion or defense of disputes arising hereunder, (4) all
         consolidating and consolidated financial information and all other
         accounting books and records prepared or used in connection with the
         preparation of financial statements of Seller, and (5) copies of all
         Retained E-mail. Seller agrees that all such information shall be
         treated as Confidential Information of Purchaser as within the meaning
         of the Operation and Maintenance and Administrative Services Agreement
         and shall be subject to the terms and conditions of the confidentiality
         provisions contained therein.

                (iv)     Notwithstanding anything to the contrary set forth in
         this Agreement, the obligations of confidentiality hereof, as they
         relate to the transactions contemplated hereby, shall not apply to the
         federal tax structure or federal tax treatment of such transactions,
         and each Party (and any employee,

                                       24

         representative, or agent of any Party) may disclose to any and all
         Persons, without limitation of any kind, the federal tax structure and
         federal tax treatment of such transaction. The preceding sentence is
         intended to cause the transactions contemplated hereby not to be
         treated as having been offered under conditions of confidentiality for
         purposes of Section 1.6011-4(b)(3) (or any successor provision) of the
         Treasury Regulations promulgated under Section 6011 of the Code and
         shall be construed in a manner consistent with such purpose. In

         exclusive rights to the tax structure of the transactions contemplated
         hereby or any tax matter or tax idea related to such transaction.

                (ii)     In the event that a request for additional information

         use all reasonable efforts to comply or cause to be complied with such
         request as soon as practicable after receipt of such request. Seller
         shall use its commercially reasonable efforts to obtain early
         termination of the applicable waiting period to the extent required by
         the applicable regulatory authorities pursuant to the Hart-Scott-Rodino
         Act. Notwithstanding the foregoing, nothing contained herein shall
         require Seller or the Company to sell, transfer, divest or otherwise
         dispose of any assets or properties. Seller will coordinate and
         cooperate with Purchaser in exchanging such information and providing

         information is made of Purchaser pursuant to the Hart-Scott-Rodino Act,
         Purchaser shall use all reasonable efforts to comply or cause to be
         complied with such request as soon as practicable after receipt of such
         request. Purchaser shall use its commercially reasonable efforts to
         obtain early termination of the applicable waiting period to the extent
         required by the applicable regulatory authorities pursuant to the
         Hart-Scott-Rodino Act. Notwithstanding the foregoing, nothing contained
         herein shall require Purchaser or the Company to sell, transfer, divest
         or otherwise dispose of any assets or properties. Purchaser will
         coordinate and cooperate with Seller in exchanging such information and
         providing such reasonable assistance as may be requested in connection

                (b)      Access to Information. After Closing, Purchaser will,
and will cause its counsel and independent public accountants to, afford to
representatives of Seller, including its counsel and accountants, reasonable
access at reasonable times upon prior notice and at Seller's expense to all
books, records, files and documents related to the Company or the Transmission
Business in order to permit Seller (i) to prepare and file its tax returns and
to prepare for and participate in any investigation with respect thereto, (ii)
to prepare for and participate in any other investigation and defend any
litigation relating to or involving the Seller, the Company or the Transmission
Business for which Seller may be responsible, (iii) to discharge its obligations
under this Agreement and the other Operative Documents to which it is a party
and for other reasonable purposes, and Purchaser will afford Seller reasonable
assistance in connection therewith. Purchaser will cause such records to be
maintained for not less than six years from the date of Closing (or, if longer,
any period required by applicable Legal Requirements); provided, however, that
in the event that Purchaser transfers all or a portion of the Transmission
Business to any third party during such period, Purchaser may transfer to such
third party all or a portion of the books, records, files and documents related
thereto, provided such third party transferee expressly assumes in writing the
obligations of Purchaser under this Section 6.2(b). Following the Closing Date,
and to the extent reasonably necessary to permit Seller or any of its Affiliates
to defend (including, without limitation, any related investigation, appeal or
settlement) any lawsuit, mediation, enforcement action, arbitration,
administrative hearing or other adjudicative proceeding relating to the
Transmission Business, Purchaser agrees to afford Seller and its Affiliates and
their respective accountants and counsel, during normal business hours, at no
cost to Seller other than reasonable out-of-pocket expenses, (i) reasonable
access to all employees of Purchaser or any of its Affiliates and all witnesses
subject to the control or direction of Purchaser or any of its Affiliates and

modified to exclude coverage of the Company and the Transmission Business.

         Section 6.4.    Cooperation by Seller.

expense of such audited financial statements for the Company as Purchaser may
reasonably request to comply with applicable Legal Requirements, stock exchange
rules and requirements of Purchaser's (or its designee's) lenders, including
providing reasonable access to its and the Company's accountants, employees,
work papers, books and records and financial data relating to the Company and
the Transmission Business.

Purchaser's (or its designee's) financing for the acquisition of the Company
Equity Interests, including (i) providing reasonable access to its and the
Company's accountants, officers, directors and representatives; provided,
however, Seller shall not be required to waive or modify any legal rights in

of the Operative Documents in favor of the lenders that (A) provides such
lenders with notice and the right to consent to any material modifications of
such Operative Documents; (B) provides such lenders with notice of default and
an opportunity to cure any defaults under such Operative Documents; (c) adds
such lenders under Seller's applicable insurance policies; (D) consents to an
assignment of such Operative Documents upon or in lieu of foreclosure; (E)

liability and recoupment against such lenders and its assignees or purchasers;
and (G) provides for the treatment of such Operative Documents in the event of a
bankruptcy of the Company.

from the date of this Agreement, Purchaser and Seller shall mutually agree on a
land consultant knowledgeable about pipeline land issues in Alaska, and which
shall be jointly retained by Purchaser and Seller to review Seller's land
records for the purpose of determining the land curative work, if any, necessary
to give the Company good title to any portion of the rights of way used or
necessary to conduct the Transmission Business, as it is now being conducted,
subject to Permitted Encumbrances and other defects or irregularities as would
be acceptable to a prudent pipeline operator, Seller shall, at its sole cost and
expense, perform any curative work identified by such consultant to bring
Seller's title to such state as soon as practicable; provided, however, that the
Closing shall not be delayed as a result of incompleted curative work provided
all of the other conditions precedent therefor have been satisfied. The costs
and expenses of the land consultant shall be shared equally between Purchaser
and Seller.

                                   Termination

         Section 10.1.   Termination. Subject to Section 10.2 hereof, this
Agreement and the transactions contemplated hereby may be terminated and
abandoned at any time prior to the Closing Date:

                (a)      by mutual consent of Purchaser and Seller; or

                (b)      by Purchaser or Seller at any time after 9 Months after
the effective date of this Agreement (the "Termination Date") if the Closing
shall not have occurred on or prior to such date; provided however, 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 resulted in, the failure of the Closing to
occur on or before the Termination Date; or

                (c)      by either Seller or Purchaser, if (i) there has been a
breach of any representation, warranty, covenant or agreement on the part of the
Company or Seller (in the case of termination by Purchaser) or Purchaser (in the
case of termination by Seller), which breach (A) will cause the conditions set
forth in Sections 8.2 and 8.4 (in the case of termination by Purchaser) or
Sections 8.2 and 8.3 (in the case of termination by Seller) not to be satisfied,
and (B) shall not have been cured within 20 Business Days following receipt by
the breaching party of written notice of such breach from the other party; or
(ii) any event shall have occurred which makes it impossible for the conditions
set forth in Article VIII hereof to be satisfied, provided that any termination
pursuant to this clause (ii) shall not be effective until 20 Business Days after
notice thereof is delivered by the party seeking to terminate to the other
party, and shall be automatically rescinded if (1) such condition is solely for
the benefit of the party receiving such notice and (2) such party, prior to such
20th Business Day, irrevocably waives satisfaction of such condition based on
such event; or

                (d)      by Purchaser or Seller if (i) any state or federal law,
order, rule or regulation is adopted or issued, that has the effect, as
supported by the written, reasoned opinion of outside counsel for such Party, of
prohibiting the transactions contemplated under this Agreement or causing a
Material Adverse Effect on such Party (or, in the case of the Purchaser, either
a Material Adverse Effect on the Company or a SEMCO Material Adverse Effect), or
if (ii) any court of competent jurisdiction in the United States or any state
shall have issued an order, judgment or decree permanently restraining,
enjoining or otherwise prohibiting the transactions contemplated by this
Agreement or causing a Material Adverse Effect on such Party (or, in the case of
the Purchaser, either a Material Adverse Effect on the Company or a SEMCO
Material Adverse Effect) or, in the case of the Purchaser, a SEMCO Material
Adverse Effect, and such order, judgment or decree shall have become final and
nonappealable.

         Section 10.2.   Limitation on Right to Terminate; Effect of
Termination.

                (a)      A Party shall not be allowed to exercise any right of
termination pursuant to Section 10.1 if the event giving rise to the termination
right shall be due to the willful failure of such Party seeking to terminate
this Agreement to perform or observe in any material respect any of the
covenants, or agreements hereof to be performed or observed by such Party.

                (b)      If this Agreement is terminated as permitted under
Section 10.1 hereof, such termination shall be without liability of or to any
Party to this Agreement, or any shareholder, unitholder, director, officer,
employee, agent, servant, consultant or representative of such Party; provided,
however, that if such termination shall result from the willful failure of any
Party to fulfill a condition to the performance of any other Party or to perform
a covenant of this Agreement or from a material breach by any Party to this
Agreement, then such Party shall (subject to the limitations set forth in
Section 12.1(c) and Section 12.1(d)) be fully liable for any and all damages
sustained or incurred by the other Party. If either Party to this Agreement
resorts to legal proceedings to enforce this Agreement, the prevailing Party in
such proceedings shall be entitled to recover all costs incurred by such Party
including reasonable attorney's fees, in addition to any other relief to which
such Party may be entitled.

                                      Taxes

         Section 11 .1.  Seller Tax Representations and Warranties.

                (a)      Seller represents and warrants with respect to the
Company that, except as set forth or disclosed in Section 11.1(a) of Seller's
Disclosure Schedule (i) all Tax Returns in respect of the Company and the
Transmission Business required to be filed have been filed or requests for
extensions have been timely filed, (ii) all such Tax Returns are true and
correct in all material respects, and (iii) all Taxes shown to be due on such
Tax Returns have been timely paid in full. Except as set forth in Section
11.1(a) of the Seller's Disclosure Schedule, all ad valorem taxes that are due
and payable have been paid, and there is not any property that has been omitted
from the assessment rolls of the applicable taxing authorities. Except as set
forth in Section 11.1(a) of Seller's Disclosure Schedule, no notice of
deficiency or assessment has been asserted, proposed or threatened from any
Governmental Authority with respect to liabilities for Taxes of the Company or
relating to the Company Assets that have not been fully paid or finally settled,
and any such deficiency shown in Section 11.1(a) of Seller's Disclosure Schedule
is being contested in good faith through appropriate proceedings. Except as set
in Section 11.1(a) of Seller's Disclosure Schedule, there is not in force any
extension of time with respect to the due date for the filing of any Tax Return
and there are no outstanding agreements or waivers extending the applicable
statutory periods of limitation for Taxes of the Company for any period of time.
Except as set forth in Section 11.1(a) of Seller's Disclosure Schedule, no
audits or other administrative proceedings or court proceedings are presently
pending with regard to any Taxes or Tax Returns of the Company, and neither the
Seller nor the Company has any knowledge of any threatened action, audit, or
administrative or court proceeding with respect to any Taxes or Tax Returns of
the Company. Except as set forth in Section 11.1(a) of the Seller's Disclosure
Schedule, no claim has ever been made by a Governmental Authority in a
jurisdiction where the Company does not file Tax Returns that it is or may be
subject to Taxes in that jurisdiction, and the Company has not entered into any
agreement or arrangement with any Governmental Authority that requires the
Company to take any action or refrain from taking any action.

                (b)      Seller and the Company are and will be members of an
"affiliated group" within the meaning of Section 1504 of the Code as of the
Closing Date. Except as set forth in Section 11.1(b) of the Seller's Disclosure
Schedule, the Company has no liability for the Taxes of any Person (other than
the Seller and the Company) under Treasury Regulation Section 1.1502-6 (or any
similar provision of state, local or foreign law), as a transferee or successor,
by contract, or otherwise.

                (c)      Except as set forth in Section 11.1(c) of Seller's
Disclosure Schedule, neither Seller nor the Company is a party to any
allocation, indemnification or sharing agreement, whether written or unwritten,
regarding Taxes with any Person.

<PAGE>

                (d)      Seller is not a nonresident alien individual or foreign
corporation within the meaning of Section 897 of the Code and Purchaser is not
required to withhold Tax on the Purchase Price by reason of Section 1445 of the
Code or any other provision.

                (e) Except as set forth in Section 11.1(e) of Seller's
Disclosure Schedule, there are no powers of attorney in effect relating to Taxes
of the Company.

                (f) Except as set forth in Section 11.1(f) of Seller's
Disclosure Schedule, there is no dispute or claim as to the Tax liability of any
other person as to which the Company has an indemnification obligation.

                (g) The Company has not participated in any transaction required
to be reported under Treasury Regulation Section 1.6011-4T or a successor or
predecessor thereto.

         Section 11.2.   Tax Covenants and Indemnification.

                (a)      Transfer Taxes. Seller shall be liable for all state
and local transfer, sales, use, documentary, recording, registration, stamp
transfer or similar Taxes, assessments or fees arising from the LLC Conversion.
Seller and Purchaser shall each be liable for 50% of all state and local
transfer Taxes arising from the transactions contemplated by this Agreement.
Except as provided in the foregoing sentences, Purchaser shall be liable for all
state and local, sales, use, documentary, recording, registration, stamp
transfer or similar Taxes, assessments or fees arising from the transactions
contemplated by this Agreement.

                (b)      Information. Seller and Purchaser will make available
to each other, and to any Governmental Authority, all information, records, or
documents relating to the liability or potential liability for Pre-Closing Taxes
that may be reasonably requested by a Party and will preserve such information,
records or documents until the expiration of any applicable statute of
limitations or extensions thereof, provided Seller and Purchaser shall reserve
the confidentiality of any such information, records or documents.

                (c)      Seller Indemnification. Seller shall be responsible for
and shall indemnify and hold harmless Purchaser, its subsidiaries and the
Company from and against any and all Tax claims, including any reasonable
out-of-pocket costs and expenses ("Tax losses"), resulting from, arising out of
or relating to: (i) any and all Taxes imposed on or incurred by Purchaser or the
Company as a result of a breach of the representations and warranties made in
Section 11.1 of this Article; (ii) any and all Pre-Closing Taxes imposed on,
incurred by or attributed to the Company, including Taxes arising from Section
2.2, except to the extent any such Taxes are taken into account in determining
the adjustment to the Purchase Price pursuant to Section 3.2 and (iii) any
liability imposed on the Company or any of its Subsidiaries as a result of its
membership in an affiliated, consolidated, combined or unitary group for Tax
purposes, other than a group the common parent of which was the Company
(pursuant to Treas. Reg. ss. 1.1502-6 or any analogous state, local or foreign
law or regulation) for any taxable period or portion thereof ending on or prior
to the Closing Date.


                                       35

<PAGE>

                (d)      Purchaser Indemnification. Purchaser shall be
responsible for and shall indemnify and hold harmless Seller from and against
any and all Tax claims or Tax losses resulting from, arising out of or relating
to any and all Post-Closing Taxes imposed on or incurred by the Company.

                (e)      Procedures for Indemnification. The procedures for
indemnification pursuant to this Article XI shall be conducted in a manner
consistent with Section 12.1 hereof.

                (f)      Proration of Tax Items. The Parties agree that for
purposes of allocating Tax items of the Company between Seller and Purchaser for
the Tax year that includes the Closing Date, such Tax items for such Tax year
shall be apportioned between Seller and Purchaser based upon the actual
operations of the Company during the portion of such period ending on the
Closing Date and the portion of such period beginning on the day following the
Closing Date, and each portion of such period shall be deemed to be a taxable
period (whether or not it is in fact a taxable period); provided, that ad
valorem Taxes shall be prorated on a daily basis.

                (g)      Filing Responsibility. Purchaser and the Company shall
be responsible for filing all Tax Returns and paying all Taxes due with respect
to periods ending after the Closing Date. To the extent the law permits or
requires a short period return for the period or portion thereof ending on or
before the Closing Date, Seller shall be responsible for filing such returns and
paying all Taxes due with respect to such period. Purchaser will take such steps
as are reasonably requested by Seller so that Seller will have the authority
necessary for Seller to be able to execute and timely file the Tax Returns
required to be filed by Seller.

                (h)      Tax Refunds and Tax Benefits. Any Tax refunds that are
received by Purchaser or the Company, and any amounts credited against Tax to
which Purchaser or the Company become entitled, that relate to Tax periods or
portions thereof ending on or before the Closing Date shall be for the account
of Seller, and Purchaser shall pay over to Seller any such refund or the amount
of any such credit within fifteen (15) days after receipt or entitlement
thereto. In addition, to the extent that a claim for refund or a proceeding
results in a payment or credit against any Tax by a Governmental Authority to
the Purchaser or the Company of any amount accrued as of the Closing Date,
Purchaser shall pay such amount to Seller within fifteen (15) days after receipt
or entitlement thereto.

                (i)      Control of Tax Audits. Seller shall have the right, at
its own expense, to control any audit or examination by any taxing authority
("Tax Audit"), initiate any claim for refund, contest, resolve and defend
against any assessment, notice of deficiency, or other adjustment or proposed
adjustment relating to any and all Taxes for any taxable period ending on or
before the Closing Date and relating to the Company. With respect to the items
described in the preceding sentence, Seller shall consult with Purchaser with
respect to the resolution of any such issue that would adversely affect
Purchaser, and with respect to Taxes other than income Taxes will not settle any
such issue, or file any amended return relating to such issue, without the
consent of Purchaser, which consent shall not be unreasonably withheld. Seller
will not enter into any binding agreement with any taxing authority with respect
to Taxes (other than income Taxes) for Tax periods ending or beginning after the
Closing Date. Purchaser shall have the right, at its own expense, to control any
other Tax Audit, initiate any other claim for refund, and contest, resolve and
defend against any other assessment, notice of deficiency, or other adjustment
or proposed adjustment relating to any Taxes for any taxable period beginning

                                       36

<PAGE>

before the Closing Date and ending after the Closing Date, provided, that
Purchaser shall consult with Seller with respect to the resolution of any issue
that would adversely affect Seller, and, with respect to Taxes, other than
income Taxes, will not settle any such issue, or file any amended return
relating to any such issue, without the consent of Seller, which consent shall
not unreasonably be withheld. Where consent to a settlement is withheld by the
other Party pursuant to this Section, such other Party may continue or initiate
any further proceedings at its own expense, provided that the liability of the
first Party, after giving effect to this Agreement, shall not exceed the
liability that would have resulted from the settlement or amended return.

         (j)    Cooperation on Tax Matters.

                (i)      Purchaser, the Company and Seller shall use reasonable
         efforts to cooperate fully, as and to the extent reasonably requested
         by the other Party, in connection with the filing of Tax Returns
         pursuant to this Agreement and any audit, litigation or other
         proceeding with respect to Taxes. Such cooperation shall include the
         retention and (upon the other Party's request) the preservation of
         records and information which are reasonably relevant to any such
         audit, litigation or other proceeding and making employees available on
         a mutually convenient basis to provide additional information and
         explanation of any material provided hereunder. The Seller agrees (A)
         to retain all books and records in its possession with respect to Tax
         matters pertinent to the Company relating to any taxable period
         beginning before the Closing Date until the expiration of the statute
         of limitations (and, to the extent notified by Purchaser or Seller, any
         extensions thereof) of the respective taxable periods, and to abide by
         all record retention requirements or agreements entered into with any
         taxing authority, and (B) to give the other Party reasonable written
         notice prior to transferring, destroying or discarding any such books
         and records and, if the other Party so requests, Seller shall allow
         Purchaser to take possession of such books and records.

                (ii)     Purchaser and Seller further agree,  upon request,  to
         provide the other Party with all information that either Party may be
         required to report pursuant to Section 6043 of the Code and all
         Treasury Regulations promulgated thereunder with respect to the
         transactions contemplated by this Agreement.

         (k)    Survival of Obligations. The obligations of the Parties set
forth in this Article XI shall be unconditional and absolute and shall remain in
effect until 30 days after the expiration of the applicable statute(s) of
limitations.

                                  ARTICLE XII

causes of actions, costs and expenses (including, without limitation, involving
theories of negligence or strict liability and including court costs and
attorneys' fees) ("Losses") asserted against, resulting from, imposed upon or
incurred by any of the Seller Indemnitees as a result of, or arising out of, the
breach of any of the representations and warranties (without giving effect to
any qualifications as to materiality contained therein), covenants or agreements
of Purchaser contained in this Agreement, including any failure of the
certificate delivered pursuant to Section 8.3(b) to be true and correct.

                (b)      (i) Subject to Section 12.1(d), and except for those
         matters (A) set forth in Article XI which shall be governed by the
         terms of Article XI and (B) set forth in Section 13.3, Seller shall
         indemnify, defend and hold harmless the Purchaser Indemnitees from and
         against all Losses asserted against, resulting from, imposed upon or
         incurred by any of the Purchaser Indemnitees as a result of, or arising
         out of the breach of any of the representations and warranties (without
         giving effect to any qualifications as to materiality contained therein
         other than the "Material Adverse Effect" qualification contained in
         Section 4.9(h)), covenants or agreements of Seller contained in this
         Agreement, including any failure of the certificate delivered pursuant
         to Section 8.4(b) to be true and correct.

                         (ii) Seller shall indemnify, defend and hold harmless
         the Purchaser Indemnitees from and against all Losses asserted against,
         resulting from, imposed upon or incurred by any of the Purchaser
         Indemnitees as a result of, or arising out of assets or liabilities,
         including the Excluded Assets and Excluded Obligations, which are not
         Company Assets or which are not being transferred to Purchaser
         indirectly through the purchase of the Company Equity Interests.
         Seller's indemnity obligations set forth in this Section 12.1(b)(ii)
         shall not be subject to any thresholds, de minimus amounts, deductibles
         or caps pursuant to Section 12.1(d).

                (c)      Notwithstanding anything to the contrary in this
Agreement, the liability of Purchaser under this Agreement and any documents
delivered in connection herewith or contemplated hereby (other than the
Operating Documents) shall be limited as follows:

                         (i)      In no event shall any amounts be recovered
         from Purchaser under Section 12.1(a) or otherwise for any matter for
         which a Claim Notice is not delivered to Purchaser, in the case of
         indemnity for breach of a representation, warranty, covenant or
         agreement, prior to the close of business on the date of termination of
         such representation, warranty, covenant or agreement pursuant to
         Section 12.1(c)(ii).

                         (ii)     Except as otherwise specified, the
         representations, warranties, covenants and agreements of Purchaser set
         forth in this Agreement shall survive the Closing for a period of two
         years and shall terminate at 5:00 p.m., local time in Alaska, on the
         second anniversary of the Closing Date; provided, however, that any
         such representation, warranty, covenant or agreement that is the
         subject of a proper Claim Notice delivered in good faith shall survive
         with respect only to the specific matter described in such Claim Notice
         until the earlier to occur of (A) the date on which a final
         nonappealable resolution of the matter described in such Claim Notice

         this Agreement other than Section 12.1(b)(ii), Article XI and Section
         13.3, in no event shall Purchaser indemnify the Seller Indemnitees, or
         be otherwise liable in any way whatsoever to the Seller Indemnitees,
         for any Losses until the Seller Indemnitees have suffered Losses in the
         aggregate in excess of a threshold in an amount equal to $500,000,
         after which point Purchaser will be obligated to indemnify the Seller
         Indemnitees from and against all Losses; provided that the Seller
         Indemnitees shall not submit to Purchaser a claim for any Loss, the
         value of which is below $25,000.

contemplated hereby (other than the Operating Documents) shall be limited as
follows:

                         (i)      In no event shall any amounts be recovered
         from Seller under Section 12.1(b) or otherwise for any matter for which
         a Claim Notice is not delivered to Seller in the case of indemnity for
         breach of a representation, warranty, covenant or agreement, prior to
         the close of business on the date of termination of such
         representation, warranty covenant or agreement pursuant to Section

                         (ii)     The representations, warranties and covenants
         of Seller set forth in this Agreement shall survive the Closing for a
         period of two years and shall terminate at 5:00 p.m., local time in
         Alaska, on the second anniversary of the Closing Date; provided,
         however, that any such representation, warranty, covenant or agreement

         be otherwise liable in any way whatsoever to the Purchaser Indemnitees,
         for any Losses until the Purchaser Indemnitees have suffered Losses in
         the aggregate in excess of a threshold in an amount equal to $500,000,
         after which point Seller will be obligated to indemnify the Purchaser
         Indemnitees from and against all Losses; provided that the Purchaser
         Indemnitees shall not submit to Seller a claim for any Loss, the value
         of which is below $25,000.

         herein other than Section 12.1(b)(ii), Article XI and Section 13.3, in
         no event shall Seller indemnify the Purchaser Indemnitees, or be

         Agreement).

                         (v)      Seller shall have no liability for any claim
         to the extent that such claim is covered by insurance maintained by or
         for the benefit of Seller (including any such insurance coverage
         applicable to the Transmission Business, the benefit of which the
         Company will realize) and Purchaser or the Company actually receive the
         proceeds of such insurance.

                         (vi)     Seller shall have no liability in respect of
         its representation or warranty contained in Section 4.9(h) in respect
         of any event, circumstance or condition known to Purchaser or disclosed
         by Seller to Purchaser in writing prior to the Closing.

                (e)      NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS
AGREEMENT, IN NO EVENT SHALL A PARTY BE LIABLE FOR ANY EXEMPLARY, PUNITIVE,
SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES; provided,
however, that if an Indemnified Party is held liable to a third party for any of
such damages and Purchaser or Seller, as the case may be, is obligated to
indemnify such Indemnified Party for the matter that gave rise to such damages,
then Purchaser or Seller, as the case may be, shall be liable for, and obligated
to reimburse such Indemnified Party for such damages.

                (f)      All claims for indemnification under Sections 12.1(a)
or 12.1(b) shall be asserted and resolved pursuant to this Section 12.1(f). Any
Person claiming indemnification hereunder is hereinafter referred to as the
"Indemnified Party" and any Person against whom such claims are asserted
hereunder is hereinafter referred to as the "Indemnifying Party." In the event
that any Losses are asserted against or sought to be collected from an
Indemnified Party by a third party, said Indemnified Party shall with reasonable
promptness provide to the Indemnifying Party a Claim Notice. The Indemnifying
Party shall not be obligated to indemnify the Indemnified Party with respect to
any such Losses if the Indemnified Party fails to notify the Indemnifying Party
thereof in accordance with the provisions of this Agreement in reasonably
sufficient time so that the Indemnifying Party's ability to defend against the
Losses is not prejudiced. The Indemnifying Party shall have 30 calendar days
from the personal delivery or receipt of the Claim Notice (the "Notice Period")
to notify the Indemnified Party (i) whether or not it disputes the liability of
the Indemnifying Party to the Indemnified Party hereunder with respect to such
Losses and/or (ii) whether or not it desires, at the sole cost and expense of
the Indemnifying Party, to defend the Indemnified Party against such Losses;
provided, however, that any Indemnified Party is hereby authorized prior to and
during the Notice Period to file any motion, answer or other pleading that it
shall deem necessary or appropriate to protect its interests or those of the
Indemnifying Party (and of which it shall have given notice and opportunity to
comment to the Indemnifying Party) and not prejudicial to the Indemnifying

                                       40

<PAGE>

Party. In the event that the Indemnifying Party notifies the Indemnified Party
within the Notice Period that it desires to defend the Indemnified Party against
such Losses, the Indemnifying Party shall have the right to defend all
appropriate proceedings, and with counsel of its own choosing, which proceedings
shall be promptly settled or prosecuted by them to a final conclusion. If the
Indemnified Party desires to participate in, but not control, any such defense
or settlement it may do so at its sole cost and expense. If requested by the
Indemnifying Party, the Indemnified Party agrees to use reasonable efforts to
cooperate with the Indemnifying Party and its counsel in contesting any Losses
that the Indemnifying Party elects to contest or, if appropriate and related to
the claim in question, in making any counterclaim against the Person asserting
the third party Losses, or any cross-complaint against any Person. No claim may
be settled or otherwise compromised without the prior written consent of the
Indemnifying Party, and no claim may be settled or otherwise compromised without
the prior written consent of the Indemnified Party (which consent shall not be
unreasonably withheld, conditioned or delayed) unless the sole relief provided
is monetary damages that are paid in full by the Indemnifying Party.

                (g)      The rights, remedies and obligations of the Purchaser
Indemnitees and the Seller Indemnitees set forth in this Section 12.1 and
Article XI will be the exclusive rights, remedies and obligations of such
Persons after the Closing with respect to this Agreement, the events giving rise
to this Agreement and the transactions provided for herein or contemplated
hereby or thereby.

                (h)      WITHOUT LIMITING OR ENLARGING THE SCOPE OF THE
INDEMNIFICATION OBLIGATIONS SET FORTH IN THIS AGREEMENT, AN INDEMNIFIED PARTY
SHALL BE ENTITLED TO INDEMNIFICATION HEREUNDER IN ACCORDANCE WITH THE TERMS
HEREOF, REGARDLESS OF WHETHER THE LOSS OR CLAIM GIVING RISE TO SUCH
INDEMNIFICATION OBLIGATION IS THE RESULT OF THE SOLE, CONCURRENT OR COMPARATIVE
NEGLIGENCE, STRICT LIABILITY, VIOLATION OF ANY LAW OR OTHER LEGAL FAULT OF OR BY
SUCH INDEMNIFIED PARTY. THE PARTIES AGREE THAT THIS PARAGRAPH CONSTITUTES A
CONSPICUOUS LEGEND.

         Section 12.2.   Disclaimer Regarding Transmission Business. Except as
otherwise expressly provided in this Agreement, Purchaser ACKNOWLEDGES THAT
SELLER HAS NOT MADE, AND SELLER HEREBY EXPRESSLY DISCLAIMS AND NEGATES, ANY
REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, RELATING TO THE CONDITION OF ANY
REAL PROPERTY, EQUIPMENT, INVENTORY, MACHINERY, FIXTURES AND PERSONAL PROPERTY

MATERIALS INTO THE ENVIRONMENT OR PROTECTION OF THE ENVIRONMENT OR HEALTH, IT
BEING THE EXPRESS INTENTION OF PURCHASER AND SELLER THAT (EXCEPT TO THE EXTENT
EXPRESSLY PROVIDED IN ARTICLES IV AND XI) THE COMPANY ASSETS SHALL BE INDIRECTLY
CONVEYED TO PURCHASER "AS IS," "WHERE IS" AND IN THEIR PRESENT CONDITION AND
STATE OF REPAIR AND PURCHASER REPRESENTS TO SELLER THAT PURCHASER HAS MADE OR
CAUSED TO BE MADE SUCH INSPECTIONS WITH RESPECT TO THE COMPANY ASSETS AS
PURCHASER DEEMS APPROPRIATE AND PURCHASER WILL ACCEPT THE COMPANY ASSETS "AS

                                  ARTICLE XIII

                                  Miscellaneous

         Section 13.1.   Modification. This Agreement may be modified, amended
or supplemented in any manner and at any time only by a written instrument
executed by Purchaser and Seller.

         Section 13.2.   Entire Agreement. This Agreement supersedes any and all
other agreements, oral or written, among the Parties in respect of the subject
matter of this Agreement.

         Section 13.3.   Expenses. Whether or not the transactions contemplated
herein shall be consummated, each Party shall (except as otherwise specifically
provided herein) pay its own expenses incident to the preparation and
performance of this Agreement, including broker's and finder's fees and
commissions; and each Party shall indemnify and hold harmless the other Party
with respect to broker's and finder's fees and commissions incurred by the
indemnifying party in connection with the transactions contemplated by this
Agreement.

         Section 13.4.   Extension and Waiver. The Parties may, to the extent
legally allowed (a) extend the time for the performance of any of the
obligations or other acts of the other Parties; (b) waive any inaccuracies by
the other Party in the representations and warranties contained herein or in any
document delivered pursuant hereto; and (c) waive compliance by the other Party
with any of the agreements or conditions contained herein. Any agreement on the
part of a Party to any such extension or waiver shall be valid only if set forth
in a written instrument signed by the Party or Parties to be bound thereby, but
such extension, waiver or failure to insist on strict compliance with an
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure. The failure of any
Party to assert any of its rights hereunder shall not constitute a waiver of
such rights.

         Section 13.5.   Further Actions. From time to time after the Closing
Date, each Party shall execute and deliver such other certificates, agreements,
conveyances, certificates of title, and other documents and take such other
actions as may reasonably be requested by the other Parties in order to
consummate or implement the transactions contemplated by this Agreement.

         Section 13.6.   Notices. Any and all notices or other communications
required or permitted under this Agreement shall be given in writing and
delivered in person or sent by United States certified or registered mail,

         Section 13.7.   Assignment. This Agreement and all of the provisions
hereof shall be binding upon and inure to the benefit of the Parties and their
respective successors and permitted assigns, but neither this Agreement nor any
of the rights, interests or obligations hereunder shall be assigned, by
operation of law or otherwise, by any Party without the prior written consent of
the other Party; provided, however, (i) Purchaser may assign its right to
purchase the Company Equity Interests to any Person in which it owns an equity
interest and with respect to which it has the right to appoint 50% or more of
the members of the board of directors, management committee or equivalent
governing body, but no such assignment shall affect Purchaser's obligations
hereunder, and (ii) in the event of any such assignment by a Party by operation
of law without the consent of the other Party as required above, such other
Party may consent to such assignment after it has occurred and, in such event,
this Agreement and all the provisions hereof shall be binding upon the Person
receiving such assignment by operation of law.

         Section 13.8.   No Third Party Beneficiaries. Nothing in this Agreement
shall provide any benefit to any third party or entitle any third party to any
claim, cause of action, remedy or right of any kind, it being the intent of the
Parties that this Agreement shall not be construed as a third party beneficiary
contract; provided, however, that the indemnification provisions in Section 12.1
shall inure to the benefit of the Purchaser Indemnitees and the Seller
Indemnitees as provided therein.

         Section 13.9.   Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any adverse
manner to either Party. Upon such determination that any term or other
provisions is invalid, illegal or incapable of being enforced, the Parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the Parties as closely as possible in an acceptable manner to the end
that the transactions contemplated hereby are fulfilled to the extent possible.

         Section 13.10.  Counterparts. This Agreement may be executed in
multiple counterparts, all of which shall constitute one and the same
instrument.

         Section 13.11.  Applicable Law; Alternative Dispute Resolution.

                (a)      This Agreement shall be governed by and construed in
accordance with the domestic laws of the State of New York without giving effect
to any choice or conflict of law provision or rule (whether of the State of New
York or any other jurisdiction) that would cause the application of the laws of
any jurisdiction other than the State of New York.

                (b)      Any dispute arising under this Agreement or otherwise
in connection with or relating to the transactions contemplated hereby shall be
resolved pursuant to this Section 13.11(b):

                         (i)      Any Party has the right to request the other
         to meet to discuss a dispute. The Party requesting the meeting will
         give at least 10 Business Days notice in writing of the subject it
         wishes to discuss, provide a written statement of the dispute, and
         designate an officer of the Party with complete power to resolve the
         dispute to attend the meeting. Within five Business Days after receipt
         to such request, the Party receiving the request will provide a
         responsive written statement and will designate an officer of the Party
         who will attend the meeting with complete power to resolve the dispute.

                         (ii)     If the meeting fails to resolve the dispute by
         a signed agreement among the officers, either Party may submit the
         dispute for binding arbitration administered by the American
         Arbitration Association ("AAA") under its Commercial Arbitration Rules
         before a single arbitrator, and judgment on the award rendered by the
         arbitrator may be entered in any court having jurisdiction thereof.

                         (iii)    The Parties agree to make discovery and
         disclosure of all matters relevant to the dispute to the extent and in
         the manner provided by the Federal Rules of Civil Procedure. The
         arbitrator will rule on all requests for discovery and disclosure and
         discovery shall be completed within 90 days of the date of the first
         notice pursuant to Section 13.11(b)(i). The arbitrator may consider any
         matter relevant to the subject to the dispute and shall follow the
         statutes and decisions of the substantive law of New York relevant to
         the subject. The arbitrator shall not have the authority or power to
         alter, amend or modify any of the terms and conditions of this
         Agreement. The arbitrator shall issue a final ruling within 180 days of
         the date of the first notice pursuant to Section 13.11(b)(i).

                         (iv)     The ruling of the arbitrator shall be in
         writing and signed and shall be final and binding upon the Parties. The
         fees and expenses of counsel, witnesses and employees of the Parties
         and all other costs and expenses incurred exclusively for the benefit
         of the Party incurring the same shall be borne by the Party incurring
         such fees and expenses. All other fees and expenses including, without
         limitation, compensation for the judge, shall be divided equally
         between the Parties. All meetings and arbitrations held pursuant to
         this Section 13.11 shall take place in the Borough of Manhattan, New
         York, New York.

         Section 13.12.  Publicity. From the date hereof until the Closing Date,
all press releases or other public communications of any nature whatsoever
relating to the transactions contemplated by this Agreement and the Operative
Documents, and the method of the release for publication thereof, shall be
subject to the prior mutual approval of Seller and Purchaser which approval
shall not be unreasonably withheld by any Party; provided, however, that,
nothing herein shall prevent any party from publishing such press releases or
other public communications as such Party may consider necessary in order to
satisfy such Party's legal or contractual obligations after such consultation
with the other Parties hereto as is reasonable under the circumstances.

<PAGE>

         Section 3.3. No Breach. Notwithstanding anything to the contrary
contained herein, Operator shall not be deemed to be in breach of its
obligations hereunder to the extent such breach is caused by any of the
following: (a) the failure of Owner to grant its consent within a reasonable
time after a request by Operator therefor to any matter requiring such consent
prior to Operator's performance of its obligations with respect to such matter,
(b) the failure of Owner to provide funds that are required by the terms of this
Agreement to be provided by Owner, (c) the failure of Owner to approve any
Capital Improvements that are necessary for Operator to perform such obligations
in accordance with the terms hereof, or (d) any acts of Operator based solely in
reliance upon a direction of Owner.

                              Capital Improvements

         Section 4.1. Capital Improvements Budget.

                  (a) The Parties agree that the capital improvements budget
attached hereto as Schedule 4.1 is the approved capital improvements budget for
the remainder of 2003 and for calendar year 2004 and shall be the "Annual
Capital Improvements Budget" for such periods.

                  (b) On or before each October 1, beginning October 1, 2004,
Operator shall submit to Owner a written budget for any Capital Improvements to
the Pipeline System (the "Proposed Annual Capital Improvements Budget") to be
made during the next calendar year (A) that Operator deems reasonably necessary
to ensure that (i) the Pipeline System has the capability to serve its customers
in accordance with its obligations to those customers, and (ii) Operator can
continue to operate the Pipeline System in accordance with applicable Laws and
Accepted Gas Pipeline Practices, or (B) that Operator believes to be desirable
to enhance the efficiency and/or profitability of the Pipeline System. The
Proposed Annual Capital Improvements Budget shall set forth the categories of
expenditures, and the total amount of each category for all Capital Improvements
that Operator proposes to make to the Pipeline System during the calendar year
covered by the Proposed Annual Capital Improvements Budget and shall include
both Direct Costs and Indirect Costs. Owner shall approve or disapprove each
category of expenditures for Capital Improvements and the total amount of such
expenditures for each category by written notice to Operator received within
sixty (60) days after Owner's receipt of such Proposed Annual Capital
Improvements Budget, and the budget as approved by the Owner shall be the
"Annual Capital Improvements Budget" for the period covered thereby. Should
Owner desire any Capital Improvements that are not covered by the current Annual
Capital Expenditure Budget, Owner may at any time request that Operator prepare
and submit to Owner plans for such requested Capital Improvements, including a
budget for the construction thereof. Upon receipt of such plans, budget and
schedule, Owner shall approve such plans or notify Operator of Owner's decision
not to proceed with such requested Capital Improvements.

         Section 4.2. Emergency Capital Improvements. In the event that due to
an explosion, fire, storm, earthquake or other emergency, the Pipeline System
suffers damage which might threaten life or property, and emergency repairs in
the nature of Capital Improvements are required to avoid injury to life or
property, Operator may make such emergency Capital Improvements as are necessary
to prevent injury to life or property without Owner's prior approval and shall
be entitled to reimbursement by Owner for such expenditures, but shall notify
Owner of the expected scope and cost of such Capital Improvements and seek
Owner's approval as promptly as practicable.

         Section 4.3. Making Capital Improvements. Except for Capital
Improvements necessitated by emergency as provided for in Section 4.2, no
Capital Improvements shall be made to the Pipeline System unless covered by the
Annual Capital Improvements Budget or approved in writing by Owner.

         Section 4.4. Scope of Capital Improvements Services. Operator shall
provide or cause to be provided all labor, services, supervision, inspection,
testing, training, systems, equipment, machinery, materials and supplies that
are necessary to (a) obtain all easements and rights of way required for the
construction and operation of each Capital Improvement, (b) obtain and maintain
in the name of Owner all Governmental Approvals required for the design,
construction, ownership and operation of each Capital Improvement, and (c)
accomplish the performance and completion of the construction of each Capital
Improvement. Operator shall use commercially reasonable efforts to perform and
complete the construction of each Capital Improvement in accordance with the
budget approved therefor by Owner, but Operator does not guarantee performance
of such activities within the approved budget. If Operator determines that an
approved Capital Improvement cannot be completed within the budget therefor,
Operator shall promptly notify Owner and propose any necessary modifications to
the budget. If Owner does not agree to increase the budget by the amount of any
estimated overage, Operator shall have the right to abandon work on the affected
Capital Improvement upon completion of all of the work that can be performed
within the original budget.

         Section 4.5. Status Reporting, Adjustments to Budgets. Operator shall
notify Owner in a reasonable amount of time of any delay in the schedule of any
approved or emergency Capital Improvement, and of any event, occurrence,
condition or circumstance that is reasonably likely to cause a material increase
in the cost of any Capital Improvement. In the event of an occurrence that
causes the costs of a Capital Improvement to materially exceed the approved
budget therefor, the Contract Administration Officers shall meet at the earliest
mutually convenient date and agree on the proper course of action and to make
any adjustments to the affected Annual Capital Improvements Budget.

         Section 4.6. Rights in Data and Work. Capital Improvements to the
Pipeline System, including all plans, drawings, specifications, calculations,
manuals and other documents and work product prepared by or for Operator in
connection with the design, engineering, construction, testing and placing in
service of any Capital Improvement, shall be owned by Owner.

River, as set out in the document entitled "Scope of Work: Susitna River
Crossing" dated [date to be inserted at Closing], is $5,200,000. Notwithstanding
anything contained in this Article IV to the contrary, if the aggregate cost of
such Capital Improvement Services (including all Direct Costs and Indirect
Costs) exceeds $5,200,000, Operator shall be entitled to reimbursement for only
10% of such costs in excess of $5,200,000, and if the aggregate of such costs is
less than $5,200,000, Operator shall be entitled (and Owner shall pay to
Operator) a bonus of 90% of the difference between $5,200,000 and such costs.

contemplated by this Section prior to the date hereof, and Owner agrees on the
date hereof to reimburse Operator for any such amounts expended by Operator,

Operator and their respective representatives full access to all information,
data and records relating to the Pipeline System and the Transmission Business,
and Operator shall comply with all reasonable requests by Owner or Successor
Operator in connection with taking over the operation and maintenance and
administration duties, including the execution and delivery of documents and
taking of other actions, in each case as shall be necessary to facilitate the
orderly transition of duties from Operator to Successor Operator.

                  (b) Promptly after the expiration or termination of this
Agreement under this Article V, Operator shall deliver to (and shall, with
effect from the expiration or termination, hold in trust for) Owner or Successor
Operator (if so directed by Owner), all work, property, recorded information and
relevant Governmental Approvals that are in Operator's possession or under
Operator's control. Operator shall use all reasonable efforts to transfer to
Owner or Successor Operator, from the expiration or termination date, its right
and obligations under all contracts entered into in connection with the
performance of its obligations under this Agreement or relating to the operation
and maintenance of the Pipeline System and the administration of the
Transmission Business and all relevant Governmental Approvals held by Operator;
provided, however, that Owner shall assume, or shall cause Successor Operator to
assume, all of Operator's rights and obligations under such contracts and
Governmental Approvals and shall indemnify, hold harmless and defend Operator
from and against any and all Losses which (i) are entirely caused subsequent to
such assumption, (ii) arise out of, result from or relate to such contracts or
Governmental Approvals and (iii) are not the direct or indirect result of acts
or omissions by Operator.

                  (c) At the request of Owner, upon the expiration or
termination of this Agreement under this Article V, Operator shall not assert
its rights, if any, to retain its personnel who spend 75% or more of their time
on matters relating to the Pipeline System or the Transmission Business and
shall otherwise permit such personnel to transfer to the employ of Successor
Operator and will offer to sell Owner any equipment and other items of personal
property used by Operator primarily to provide Services under this Agreement for
a price equal to the book value thereof on Operator's books.

                                   ARTICLE VI

                                  Compensation

         Section 6.1. Compensation for Operation and Maintenance Services.

                  (a) As compensation for all Operation and Maintenance Services
during the first three years of the Service Term, Owner shall pay Operator
$334,000 per calendar month (the "Monthly O&M Payment") (with appropriate
proration for partial months). For the fourth and fifth years of the Service
Term, the Monthly O&M Payment shall be an amount determined by multiplying the
difference between $334,000 and 1/12 of the Operator's actual Direct Costs for
Taxes and insurance for the first year of the Service Term by the CPI Inflator
for such year, and in addition, Owner shall reimburse Operator for Operator's
actual Direct Costs for Taxes and insurance in such years, appropriately pro
rated if assessed or changed for a period different than such years.

                  (b) Payment for the calendar month in which the Effective Date
occurs shall be due on the Effective Date. Payment of the Monthly O&M Payment
for each succeeding calendar month during the first three years of the Service
Term, and after the amount thereof has been determined, the fourth and fifth
years of the Service Term, shall be due, without invoice, on the first Business
Day of such month. Payment for Taxes and insurance during the fourth and fifth
years of the Service Term shall be due ten (10) days after receipt by the Owner
of an invoice therefore. The compensation payable to Operator for the provision
of Operation and Maintenance Services is intended to reimburse Operator for all
Direct Costs and Indirect Costs of providing such Services, and Operator shall
be solely responsible for payment of such costs, including, but not limited to
all of the costs related to the categories specified in Exhibit B. All past due
payments for Operation and Maintenance Services shall bear interest at the
Interest Rate from the due date until paid.

         Section 6.2. Adjustment of Monthly O&M Payment on Change of Law. The
Monthly O&M Payment is intended to remain the fixed payment specified in Section
6.1 for each year of the Service Term regardless of Operator's actual costs of
providing Operations and Maintenance Services. Notwithstanding the foregoing,
however, if as a result of a change in applicable Laws, Operator's costs are
materially increased or decreased, the Monthly O&M Payment shall be increased or
decreased, as applicable, by the amount necessary to compensate Operator for its
increased costs or reduce the compensation to Operator for its decreased costs
attributable to such change of Law.

         Section 6.3. Reimbursement for Capital Improvements Services. All
Capital Improvements Services shall be performed by Operator on a cost
reimbursement basis, and Owner shall reimburse Operator for all Direct Costs and
Indirect Costs of providing such Services.

                                  ARTICLE VII

                      Billing and Payment of Costs Services

         Section 7.1. Invoices for Services. On or before the fifteenth day of
each month, Operator shall provide to Owner one or more written invoices,
setting out the total amount due Operator for Capital Improvements Services
during the preceding month, showing a comparison of the invoiced costs for each
category to the amounts budgeted for such category, together with such
supporting documentation for all such costs as shall be reasonably requested by
Owner. Items properly invoiced and not disputed in good faith by Owner are due
and payable within ten (10) days of Owner's receipt of such invoice. Owner shall
give written notice on or before the due date of any invoice of any good faith
dispute of all or any portion of such invoice, with the particulars of such
dispute. Owner shall pay interest on any unpaid portion of the undisputed amount
of an invoice from the due date thereof up to and including the date when such
amount and interest thereon are paid in full, at the rate per annum for the
first 10 days equal to the rate published as the "prime rate" in The Wall Street
Journal for the first business day of the month in which such invoice is due,
plus 2%, and thereafter, at a rate per annum equal to 15%, but in no event at
any rate that is greater than the maximum interest rate allowed by applicable
Laws (such rate, the "Interest Rate").

         Section 7.2. Resolution of Disputes of Invoices. Owner shall provide to
the Contract Administration Officers a copy of any notice to Operator of a
dispute with respect to an Operator invoice. The Contract Administration
Officers shall promptly meet and attempt to resolve any invoice dispute by
mutual agreement. If the Parties are unable to agree upon a settlement of the
invoice dispute, the dispute shall be addressed in accordance with Article VIII.
If any invoice dispute is resolved in favor of Operator, Owner shall pay any
amount owed with interest from the date such disputed invoice was due to the
date of payment of such amount, at the Interest Rate.

         Section 7.3. Owner's Audit Rights. Owner shall have the right, at any
time within one (1) year after the date of any Operator invoice for
reimbursement of costs of Capital Improvements Services, to audit those books
and records of Operator that relate to the Capital Improvements Services covered
by such invoice, to verify the costs reflected on such invoice. Any such audit
shall be conducted by Owner or its designated auditor after ten (10) days prior
written notice to Operator, at Owner's cost and expense, during normal business
hours in the offices of Operator, or such other location as may be appropriate.
Operator shall cooperate with and provide reasonable assistance to Owner or its
auditor in connection with the performance of any such audit, at Operator's sole
cost and expense. Owner shall assert any claim for refund of the cost of Capital
Improvements Services reimbursed to Operator under the audited invoice within
sixty (60) days after the receipt of the audit report. Unless Operator notifies
Owner of any dispute to Owner's claim for refund relating to any such audit
within thirty (30) days of receipt of such refund claim, the amount of such
refund claim shall be due and payable by Operator to Owner forty (40) days after
Operator's receipt of such refund claim, together with interest at the Interest
Rate from the date of any overpayment to Operator until the date of refund of
such overpayment by Operator. Should Operator dispute the claim and refuse to
pay any refund claim by Owner resulting from the exercise of Owner's audit
rights, the dispute shall be addressed in accordance with Article VIII.

                                  ARTICLE VIII

                               Dispute Resolution

         Section 8.1. General. Any dispute arising under this Agreement or
otherwise in connection with this Agreement shall be resolved pursuant to this
Section 8.1.

                  (a) Any Party has the right to request the other to meet to
discuss a dispute. The Party requesting the meeting will give at least ten (10)
Business Days notice in writing of the subject it wishes to discuss, provide a
written statement of the dispute, and designate an officer of the Party with
complete power to resolve the dispute to attend the meeting. Within five (5)
Business Days after receipt of such request, the Party receiving the request
will provide a responsive written statement and will designate an officer of the
Party who will attend the meeting with complete power to resolve the dispute.

                  (b) If the meeting fails to resolve the dispute by a signed
agreement among the officers, either Party may submit the dispute for binding
arbitration administered by the American Arbitration Association ("AAA") under
its Commercial Arbitration Rules before a single arbitrator, and judgment on the
award rendered by the arbitrator may be entered in any court having jurisdiction
thereof.

                  (c) The Parties agree to make discovery and disclosure of all
matters relevant to the dispute to the extent and in the manner provided by the
Federal Rules of Civil Procedure. The arbitrator will rule on all requests for
discovery and disclosure and discovery shall be completed within 60 days after
the date of appointment of the arbitrator. The arbitrator may consider any
matter relevant to the subject to the dispute and shall follow the statutes and
decisions of the substantive law of Alaska relevant to the subject. The
arbitrator shall not have the authority or power to alter, amend or modify any
of the terms and conditions of this Agreement. The arbitrator shall issue a
final ruling within 150 days after the date of appointment of the arbitrators.

                  (d) The ruling of the arbitrator shall be in writing and
signed and shall be final and binding upon the Parties. The fees and expenses of
counsel, witnesses and employees of the Parties and all other costs and expenses
incurred exclusively for the benefit of the Party incurring the same shall be
borne by the Party incurring such fees and expenses. All other fees and expenses
including, without limitation, compensation for the arbitrator, shall be divided
equally between the Parties. All meetings and arbitrations held pursuant to this
Section 8.1 shall take place in Anchorage, Alaska.

                  (a) reporting to senior management of their respective

Improvements; and

                  (c) monitoring the costs of Capital Improvements Services.

                                   ARTICLE X

                         Confidentiality of Information

         Section 10.1. General. As used in this Article X (and in Section 14.2),
"Confidential Information" shall mean any information not in the public domain
or generally known in the industry, in any form relating to the business and
operations of Owner or Operator (each such entity, for purposes of this Article
X, a "Company"), including but not limited to information regarding customers,
vendors, suppliers, trade secrets, training programs, manuals or materials,
technical information, contracts, systems, procedures, mailing lists, know-how,
trade names, improvements, price lists, financial or other data (including the

programs, software systems, databases, disks and printouts, plans (business,
technical or otherwise), customer and industry lists, correspondence, internal
reports, personnel files, sales and advertising material, telephone numbers,

which is or was used by such Company, regardless of whether such information was
or is owned during the term of this Agreement by such Company.

         Section 10.2. Operator's Obligations. Operator shall maintain the
confidentiality of any Confidential Information of Owner acquired by Operator
during the term of this Agreement, and except as otherwise provided in this
Agreement, shall not use such Confidential Information for any purpose other
than the performance of this Agreement; provided, however, Operator may use any
Confidential Information in the resolution of any disputes under this Agreement.
Upon termination of this Agreement, except as otherwise provided in this
Agreement, Operator agrees to turn over such Confidential Information to Owner
or to destroy such Confidential Information, but only in accordance with the
instructions of Owner; provided, however, that Operator may maintain one archive
copy of all of such Confidential Information in a secure data storage facility.

         Section 10.3. Owner's Obligations. Owner shall maintain the

in this Agreement, Owner agrees to turn over such Confidential Information to
Operator or to destroy such Confidential Information in accordance with the
instructions of Operator; provided, however, that Owner may maintain one archive

         Section 10.4. Compulsory Disclosure. If any Company is requested or
required to disclose Confidential Information of another unaffiliated Company
pursuant to any judicial or administrative process, law, regulation or statute,
then such receiving Company shall promptly notify the other unaffiliated Company
to this Agreement in writing of such request or requirement. The Company whose
Confidential Information is requested or required to be disclosed shall either
(i) promptly seek protective relief from such disclosure obligation or (ii)
direct the receiving Company to comply with such request or requirement. If,
after a reasonable opportunity to seek protective relief, such relief is not
obtained by the Company whose Confidential Information is subject to discovery
or disclosure, or if such Company fails to obtain such relief, the receiving
Company may disclose such portion of such Confidential Information that such
Company reasonably believes it is legally obligated to disclose.

         Section 10.5. Injunction. Each Company agrees that the breach by
another unaffiliated Company of its obligations under this Article X would cause
significant and irreparable harm to the aggrieved Company, which may be
difficult to measure with certainty or to compensate through money damages. Each
Company acknowledges that the aggrieved Company shall be entitled, without proof
of irreparable harm and without waiving any other right or remedy available to
it, to such injunctive and equitable relief as may be deemed proper by a court
of competent jurisdiction.

                        Relationship BETWEEN the Parties

         Section 11.1. No Joint Venture. It is the intent of the Parties that
with respect to the provision of the Services pursuant to this Agreement, Owner
and Operator are independent contractors. Except to the extent Operator executes
contracts or documents as the agent of Owner pursuant to the terms of Section
16.1, nothing in this Agreement shall cause the relationship between Operator
and Owner to be deemed to constitute an agency, partnership or joint venture.
The terms of this Agreement are not intended to constitute a joint employer for
any purpose between any of the Parties and their affiliates. Each of the Parties
agrees that the provisions of this Agreement as a whole are not intended to, and
do not, constitute control of the other Party (or any affiliates thereof) or
provide it with the ability to control such other Party (or any affiliates
thereof), and each Party hereto expressly disclaims any right or power under
this Agreement to exercise any power whatsoever over the management or policies
of the other (or any affiliates thereof). Nothing in this Agreement shall oblige
either Party hereto to act in breach of the requirements of applicable Laws or
Governmental Approvals.

         Section 11.2. Certain Labor Matters. The Parties recognize that
Operator is subject to collective bargaining agreements covering certain of its
employees and will perform the Services under this Agreement in compliance with
the terms of such collective bargaining agreements. Operator shall ensure that
upon the termination of the Service Term, Owner shall have no obligation or
liability in respect of such collective bargaining agreements.

                               Regulatory Matters

         Section 12.1. Compliance with Regulatory Requirements. Operator will
cooperate with Owner and any Governmental Authority that regulates Owner and/or
the Pipeline System to satisfy any regulatory requirements applicable to the
Pipeline System.

                                  ARTICLE XIII

                  Indemnification; Release; Limit on Liability

         Section 13.1. Indemnification by Operator. Operator shall indemnify,
defend and hold harmless Owner, and each of its officers, directors, employees,
agents, and affiliates (and the officers, directors, employees and agents of
such affiliates) ("Owner Indemnified Party") if any such Owner Indemnified Party
shall at any time or from time to time suffer any damage, judgment, fine,
penalty, demand, settlement, liability, loss, cost, expense (including
reasonable attorneys', consultants' and experts' fees), claim or cause of action
(each, a "Loss") arising out of, relating to or resulting from the Operator's
performance of this Agreement, to the extent such Loss results from any breach
of this Agreement or the fault, tortuous act, negligence, strict liability,
gross negligence or willful misconduct of Operator. Further, Operator shall
indemnify and hold Owner harmless and defend Owner from (i) any and all claims,
costs, damages, injuries, demands and causes of action commenced by an employee
of Operator (or his or her estate or legal representative) which arises directly
or indirectly from the performance of Services except to the extent that such
Loss directly results from the gross negligence or willful misconduct of Owner,
and (ii) any and all Losses arising out of or resulting from any collective
bargaining agreements covering employees of Operator, including, without
limitation, those collective bargaining agreements referenced in Section 11.2.

         Section 13.2. Indemnification by Owner. Owner shall indemnify, defend
and hold harmless Operator, and each of its officers, directors, employees,
agents, and affiliates (and the officers, directors, employees and agents of
such affiliates) ("Operator Indemnified Party") if any such Operator Indemnified
Party shall at any time or from time to time suffer any Loss arising out of,
relating to or resulting from Owner's performance of this Agreement, to the
extent such Loss results from any breach of this Agreement or the fault,
tortuous act, negligence, strict liability, gross negligence or willful
misconduct of Owner. Further, Owner shall indemnify and hold Operator harmless
and defend Operator from any and all claims, costs, damages, injuries, demands
and causes of action commenced by an employee of Owner (or his or her estate or
legal representative), except to the extent that (i) such Loss directly results
from the gross negligence or willful misconduct of Operator, or (ii) Owner is
entitled to indemnity from Operator under Section 13.1.

<PAGE>

         Section 13.3. Procedures. Any Party asserting a claim for
indemnification hereunder (such Party seeking indemnification, the "Indemnified
Party") shall notify the other Party (the "Indemnifying Party") (with reasonable
specificity) promptly after it becomes aware of facts supporting a claim or
action for indemnification under this Article XIII, and shall provide to the
Indemnifying Party as soon as practicable thereafter all information and
documentation reasonably necessary to support and verify any Losses associated
with such claim or action. The failure to so notify or provide information to
the Indemnifying Party shall not relieve the Indemnifying Party of any liability
that it may have to any Indemnified Party, except to the extent that the
Indemnifying Party demonstrates that it has been materially prejudiced by the
Indemnified Party's failure to give such notice, in which case the Indemnifying
Party shall be relieved from its obligations hereunder to the extent of such
material prejudice. The Indemnifying Party may, and, at the request of the
Indemnified Party, shall participate in and defend, contest or otherwise protect
the Indemnified Party against any such claim or action by counsel of the
Indemnifying Party's choice at its sole cost and expense; provided, however,
that the Indemnifying Party shall not make any settlement or compromise without
the prior written consent of the Indemnified Party (which consent shall not be
unreasonably withheld, conditioned or delayed) unless the sole relief provided
is monetary damages that are paid in full by the Indemnifying Party. The
Indemnified Party shall have the right, but not the obligation, to participate
at its own expense in the defense thereof by counsel of the Indemnified Party's
choice and shall in any event use its reasonable best efforts to cooperate with
and assist the Indemnifying Party. If the Indemnifying Party fails timely to
defend, contest or otherwise protect against such suit, action, investigation,
claim or proceeding, the Indemnified Party shall have the right to do so,
including, without limitation, the right to make any compromise or settlement
thereof, and the Indemnified Party shall be entitled to recover the entire cost
thereof from the Indemnifying Party, including, without limitation, reasonable
attorneys' fees, disbursements and amounts paid as the result of such suit,
action, investigation, claim or proceeding.

         Section 13.4. Indemnification Payments. Any payment hereunder shall be
made by wire transfer of immediately available funds to such account or accounts
as the Indemnified Party shall designate to the Indemnifying Party in writing.

         Section 13.5. Survival. The provisions of this Article XIII shall
survive the termination of this Agreement for claims made within a period of
three (3) years after the expiration date of the Service Term.

         Section 13.6. Release and Limit on Liability. Operator shall not be
liable to Owner for, and Owner hereby releases Operator and its affiliates, and
each officer, director, employee and agent of Operator and/or any of its
affiliates (the "Operator Parties") from, any Loss arising from any act or
omission of Operator in connection with the Services, except to the extent any
such Loss results from an event for which Owner is entitled to indemnification
under Section 13.1. Owner shall not be liable to Operator for, and Operator
hereby releases Owner and its affiliates, and each officer, director, employee
and agent of Owner and/or any of its affiliates (the "Owner Parties") from, any
Loss arising from any act or omission of Owner in connection with the Services,
except to the extent any such Loss results from an event for which Operator is
entitled to indemnification under Section 13.2. Notwithstanding anything in this
Agreement to the contrary, the aggregate liability of the Operator Parties under
this Agreement (other than with respect to Operator's indemnity obligations set
out in clause (ii) of the last sentence of Section 13.1, which shall not be so
limited) shall not exceed the sum of (i) the aggregate amount of payments
received by Operator pursuant to Section 6.1 hereof (excluding Direct Cost
payments to vendors and other third parties), and (ii) any payments actually
received by Operator or paid to any third party on behalf of Operator in respect
to such liabilities under policies of insurance. IN NO EVENT SHALL ANY OF THE
OPERATOR PARTIES BE LIABLE TO ANY OF THE OWNER PARTIES, NOR SHALL ANY OF THE
OWNER PARTIES BE LIABLE TO ANY OF THE OPERATOR PARTIES, FOR SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL OR PUNITIVE LOSS, DAMAGES OR EXPENSES (INCLUDING LOST
PROFITS OR SAVINGS) ARISING FROM THIS AGREEMENT.

records and accounts relating to the operation and maintenance of the Pipeline
System, the conduct of the Transmission Business and the performance of the
Services and Operator's other obligations hereunder (including all operating
data and operating logs) as shall be required to comply with any contractual
obligations of Owner and as necessary to verify the incurring and payment of all
capital and operating expenditures and Operator's performance of the Services
and its other obligations hereunder. All books, records and accounts referred to
in this Section 14.1 shall be established and maintained in accordance with
generally accepted accounting principles in the United States consistently
applied, and shall be in a format sufficient to permit the verification referred
to in the preceding sentence. Operator shall ensure that such books and records
of account are kept separate from Operator's own corporate books and records.

                  (b) Operator shall maintain all books and records it is
required to maintain hereunder for a period of at least six (6) years following
the creation thereof and in all events for however long as may be required by
applicable Law.

         Section 14.2. Ownership of Books and Records. All books, records and
accounts maintained by Operator in connection with the Transmission Business
hereunder shall at all times be the exclusive property of Owner, and Operator
shall not have any rights, title or interest therein. All books, records and
accounts of Operator that Operator maintains in its own behalf in connection
with its provision of services under this Agreement shall at all times be the
exclusive property of Operator, and Owner shall not have any right, title or
interest therein, except for Owners' right to review supporting information
related to the cost of Capital Improvements Services and the monthly invoicing
process under Article VII, with a right to retain copies thereof (subject to the
confidentiality provisions of Article X). Upon termination of the provision of
any or all Services by Operator under this Agreement, all books, records, and
accounts solely relating to the Services described in the first sentence of this
Section 14.2 shall be promptly delivered to Owner at its address set forth below
and Operator shall retain no copies thereof, except that Operator shall be
entitled to retain one copy thereof solely for archival purposes and such copy
shall be treated and protected by Operator as Confidential Information of Owner
pursuant to Article X.

Operator's cost, all-risk property, builder's all-risk and time element
insurance covering the Pipeline System and the Facilities on a commercially
reasonable basis with coverages, limits, deductibles, terms and conditions as
the Owner would maintain in the prudent management of its property, or would be

Pipeline System and the Facilities. Operator shall be provided a waiver of all
rights of subrogation under such insurance, and a certificate of insurance
evidencing such insurance upon request.

         Section 15.3. Provision of Owner's Insurance By Operator. As part of
the Operations and Maintenance Services, Operator agrees to procure for Owner,
at Operator's sole cost and expense, the insurance required by Owner pursuant to
Section 15.1 and 15.2, and agrees to comply, as Owner's agent, with the
requirement of Section 7.7 of the Gas Transmission Agreement. All such policies
of insurance shall list Owner as a loss payee and a named insured and Owner's
lenders as loss payees and additional insureds, and if Operator receives any
payments in respect of such policies in respect of APC, it shall promptly remit
such payments to Owner in the form received. Operator also shall cooperate with
Owner in connection with any modifications and enhancements of the insurance
contemplated in Sections 15.1 and 15.2 requested by Owner, including any
increases in coverage or reductions in deductibles, provided that any additional
premiums resulting from such modifications and enhancements shall be paid for by

restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable, each Party directs that such court interpret and
apply the remainder of this Agreement in the manner that it determines most
closely effectuates the Parties' intent in entering into this Agreement, and in
doing so particularly take into account the relative importance of the term,
provision, covenant or restriction being held invalid, void or unenforceable.

                               MEASURING STATIONS

         Section 4.1. Transporter's Obligation to Install, Maintain and Operate
Measurement Facilities at the Receipt Point(s). Transporter shall maintain and
operate, or cause to be operated, at Transporter's expense, measurement stations
in existence on the Commencement Date or subsequently installed pursuant to
Section 5.2.1 at or near the Receipt Point(s). Unless otherwise determined by
Transporter, a Receipt Point measurement station shall consist of (a) standard
measuring equipment conforming to the requirements of American Gas Association
Gas Measurement Committee Reports now in effect or as amended or supplemented
during the term of this Agreement, (b) appurtenant facilities, (c) hydrometers,
and (d) data telemetry equipment. Shipper shall have access to the Receipt Point
measurement station(s) at which it tenders Gas at reasonable hours, but
Transporter will make or cause to be made, all calibrations, measurements and
adjustments.

         Section 4.2. Allocation of Gas Streams at Receipt Point(s). Shipper's
Gas may be commingled and measured in common with other Gas, including
Transporter's purchased Gas, at the Receipt Points. Commingled Gas shall be
allocated on a fair and reasonable basis, among the various shippers and
Transporter, by Transporter.

         Section 4.3. Transporter's Obligation to Install, Maintain and Operate
Measurement Facilities at the Delivery Point(s). The Transporter shall maintain
and operate or cause to be operated, at Transporter's expense, the existing
measurement facilities at or near the Delivery Point(s).

         Section 4.4. Estimated Volumes When Meters Are Inaccurate or Out of
Service. The volume of Gas delivered hereunder at each Receipt Point shall be
calculated in accordance with Section 5.1 and the American Gas Association
standards applicable to the type of measurement facilities installed. In the
event a meter is out of service or registering inaccurately, the volumes of Gas
delivered shall be estimated:

                  (a) by using the registration of Shipper's check meter or
meters if installed and accurately registering, or in the absence of (a),

                  (b) by correcting the error if the percentage of error is
ascertainable by calibration, test, or mathematical calculations, or in the
absence of both (a) and (b), then,

                  (c) by estimating the quantity of deliveries based on
deliveries during comparable periods under similar conditions when the meter was
registering accurately.

         Section 4.5. Verification of Accuracy of Equipment. Transporter will
test the accuracy of the measuring equipment for Receipt Points at least once a
month. If either party notifies the other that it desires a special test of the
accuracy of any measuring equipment, the parties will test promptly. Each Party
shall bear the cost of its own transportation and related expenses involved in
the testing of meters.

         Section 4.6. Accuracy Requirements: Correction. If, upon test, any
measuring equipment is found to be not more than one percent (1%) inaccurate,
previous records of such equipment shall be considered accurate. In the event
any measuring equipment is found to be inaccurate by more than one percent (1%),
at a recording corresponding to the average hourly rate of Gas flow for the
period since the last preceding test, any previous records of the equipment will
be corrected to zero error for any period known definitely or agreed upon. If a
period of inaccuracy is not definitely known or agreed upon, the correction
shall be made for a period of the lesser of sixteen (16) Days or one-half (1/2)
of the time elapsed since the date of last test. The correction shall fully
settle all claims based on the inaccuracy. Any measuring equipment found by test
to be inaccurate will be adjusted at once to measure accurately.

         Section 4.7. Preservation of Records. The Transporter shall preserve
for a period of at least six (6) Years all test data, charts, and other similar
records.

                                  MEASUREMENTS

         Section 5.1. Parameters of Measurement. The calculation of the volumes
of Gas transported hereunder shall be governed by the following:

                  (a) The unit of volume measurement shall be one (1) cubic foot
of Gas at the base temperature of sixty degrees Fahrenheit (60(degree)F.) and at
a pressure of fourteen and sixty-five hundredths (14.65) pounds per inch
absolute with correction for deviation from the Ideal Gas Law according to
ANSI/API 2530 or AGA Report No. 8, as applicable.

                  (b) The average absolute atmospheric pressure shall be assumed
to be fourteen and seven-tenths (14.7) pounds per square inch, irrespective of
actual elevation or location of the measurement point above sea level or
variations in actual atmospheric pressure.

                  (c) The specific gravity of Gas shall be determined by the use
of a spot test method or, if the parties later agree in writing, by the use of a
recording gravitometer generally accepted in the industry. If a recording
gravitometer is used, the arithmetic average of the specific gravity of Gas
flowing through the meters shall be used in computing Gas volumes. If a spot
test method is used, the specific gravity of the Gas shall be determined at
quarterly intervals, or more often if changes in specific gravity indicate that
it is necessary. Any such test shall determine the specific gravity to be used
in computation of volumes effective the first Day of the following Month and
shall be used until changed in like manner by subsequent test.

                  (d) Where determined necessary by Transporter, the actual
temperature of Gas shall be determined by a recording thermometer so installed
that it will record the temperature of the Gas flowing through the meters. The
average of the recorded temperatures to the nearest one degree Fahrenheit
(1(degree)F.) obtained while Gas is being delivered shall be used in computing
measurements for that Day.

                                   ARTICLE VI
                                     QUALITY

         Section 6.1. Heating Value of Gas.

                  (a) Gas shall have a Gross Heating Value of not less than nine
hundred fifty (950) Btu's per cubic foot nor more than one thousand fifty
(1,050) Btu's per cubic foot. Transporter shall have the right to waive such
Btu's per cubit foot content limits if Transporter is able to accept Gas outside
such limits without affecting Transporter's operations.

                  (b) The Gross Heating Value of Gas shall be determined from a
representative composite Gas sample taken at the point of measurement by
periodic tests to be conducted monthly by Transporter or at such other intervals
as the parties may mutually agree. The determination shall be made by means of a
calorimeter by calculation from the component analysis using NGPA Publication
2145, as it may be revised, entitled "Physical Constants of Paraffin
Hydrocarbons or Other Compounds of Natural Gas."

commercially free of dust, gum, gum-forming constituents, or other liquid or
solid matter which may separate from the Gas in transportation, shall not exceed
one hundred twenty degrees Fahrenheit (120(degree) F.), and shall not contain:

                  (a) more than four (4) pounds of water per million cubic feet
of Gas;

                  (b) more than one (1) grain of hydrogen sulfide per one
hundred (100) cubic feet of Gas;

                  (c) more than twenty (20) grains of sulphur per one hundred
(100) cubic feet of Gas;

                  (d) in excess of:

                      (i) three percent (3%) by volume of carbon dioxide; or

                      (ii) one percent (1%) by volume of oxygen.

         Section 6.3. Transporter's Right to Refuse Gas. Transporter shall have
the right to refuse to accept delivery of any Gas failing to meet the quality
requirements of this Article VI.

                                  ARTICLE VII
                                CHARGES & BILLING

         Section 7.1. Reservation Rate and Commodity Rate. For each Month during
the Base Term and any Renewal Term, Shipper shall pay and Transporter shall
accept as payment for Transportation service provided in accordance with this
Agreement the sum of the following amounts, each computed by use of the
applicable rates set forth on Exhibit C :

                  (a) The amount of the Reservation Rate set forth on Exhibit C
(the "Reservation Rate"); plus

                  (b) the amount, calculated by multiplying the Commodity Rate,
set forth on Exhibit C (the "Commodity Rate"), by the volumes, stated in Mcf, of
Delivered Gas during the Month.

         Section 7.2. Billing and Payment.

                  (a) Payment of the Reservation Rate for the Month in which the
Commencement Date occurs shall be due on the Commencement Date. Payment of the
Reservation Rate for each succeeding Month shall be due, without invoice, on the
first Business Day of such Month.

                  (b) With respect to amounts payable other than the Reservation
Rate, Transporter shall deliver to Shipper a monthly statement for
Transportation services for the preceding Month, which shall detail all charges
payable by Shipper during the preceding Month and the basis for the calculation
of the amount due. Shipper shall pay Transporter the full amount due by wire
transfer of immediately available funds to the account designated by Transporter
no later than ten (10) days after Shipper's receipt of such statement.

<PAGE>

                  (c) If Shipper disagrees with any statement, it shall promptly
notify Transporter in writing of its disagreement and the facts providing the
basis therefor. If the Parties are unable to agree upon a settlement of the
contested portion of a statement, the dispute shall be addressed in accordance
with Article 10. The existence of a dispute with regard to any portion of a
payment due shall not relieve Shipper of the obligation to pay any uncontested
amounts due under this Agreement or to perform any other obligation under this
Agreement. Shipper shall pay, no later than ten (10) days after Shipper's
receipt of the statement, any disputed amount into a separate interest bearing
account at First National Bank of Alaska or its successor and shall notify
Transporter of such deposit. Any interest which may accrue in such account shall
be payable to the Party in whose favor the dispute is resolved, and any such
interest actually paid shall reduce the interest payments required to be made
pursuant to subparagraph (e) to this Section 7.2 accordingly.

                  (d) Each Party shall have the right during normal business
hours to examine the books, records and charts of the other Party to the extent
necessary to verify the accuracy of any invoice related to this Agreement.
Claims for adjustments on account of subsequently discovered errors must be made
within twelve (12) Months of the date the statement was issued. The Party
discovering such an error shall promptly notify the other Party in writing of
the errors believed in good faith to have occurred and the facts providing the
basis for such belief. Adjustment of overpayments or underpayments shall be made
within ten (10) days after resolution of such subsequently discovered errors.

                  (e) If either Party shall fail to make any payment required by
this Agreement when due, including contested portions of bills, or if any Party
makes an overpayment requiring a refund by the other Party, the amount due shall
bear interest, from the due date of the payment or the date on which the
overpayment was made until the date of payment, at a rate for the first 10 days
equal to the rate published as the "prime rate" in The Wall Street Journal for
the first Business Day of the month in which such invoice is due, plus 2%, and
thereafter, at a rate per annum equal to 15%, but in no event at any rate that
is greater than the maximum interest rate allowed by applicable Laws. If the due
date of any payment is not a Business Day, then the next Business Day shall be
the last day on which payment can be paid without interest charges being
assessed.

         Section 7.3. Reimbursement for Fees and Taxes. In addition to the
transportation charges provided for in Article 7.1, Shipper will reimburse
Transporter for all user fees, taxes (except income and ad valorem taxes), and
the like, levied upon the transportation of the Gas.

                                  ARTICLE VIII
                                      TERM

         Section 8.1. Term. Although this Agreement has been executed prior to
the Commencement Date, neither party shall have any obligation hereunder until
the Commencement Date. Unless earlier terminated, this Agreement shall remain in
full force and effect for a period of ten years from the Commencement Date (the
"Base Term"). The Base Term automatically shall be extended for successive
additional one-year periods (each, a "Renewal Term"), unless either Party gives
the other Party notice of its intention to terminate this Agreement at least one
year prior to the end of the Base Term or 180 days prior to the end of the then
current Renewal Term. If the Purchase Agreement is terminated without the
purchase of Transporter contemplated therein occurring, this Agreement shall
terminate on the same date as the Purchase Agreement terminates and no Party
shall have any liability hereunder.

                                  ARTICLE III

                         TRANSPORTATION RELATED SERVICES

         Section 3.1. SEMCO's Rights and Obligations.

                  (a) SEMCO, acting for its ENSTAR division, shall have the
right during the term of this Agreement to obtain Transportation of a daily
quantity of Gas equal to the Maximum Daily Quantity on each segment of APC
System in accordance with the terms hereof and of the Special Contract. SEMCO
shall be entitled to nominate and schedule Transportation service for its ENSTAR
division up to the Maximum Daily Quantity for each Day of the Base Term and any
Renewal Term. SEMCO's right to obtain Transportation of such quantity of Gas
shall be exclusive, and APC shall reserve such portion of the Transportation
Capacity solely for SEMCO's use for its ENSTAR division. The Parties agree that
if there are ever multiple transporters on the APC System, APC and SEMCO shall
agree on the nomination and balancing provisions that shall be applicable to
this Agreement and the Special Contract. SEMCO hereby commits to Transportation
under this Agreement all Gas purchased by ENSTAR pursuant to the contracts
listed in Exhibit F other than Gas delivered to customers directly off of the
KKPL pipeline through connections to the ENSTAR System prior to the connection
between the KKPL pipeline and the APC System and which either (i) exist prior to
the date of this Agreement or (ii) if connected after the date of this
Agreement, cannot be economically served from the APC System.

                  (b) The Transportation Capacity purchased by SEMCO for its
ENSTAR division pursuant to this Agreement as set forth on Exhibit C is all of
the Transportation Capacity of APC System on the date of this Agreement. If APC
desires to increase the Transportation Capacity of any segment of APC System,
APC shall notify SEMCO. If SEMCO notifies APC within ten (10) days after receipt
of such notice that it would be interested in purchasing such increased
Transportation Capacity, then APC and SEMCO shall negotiate in good faith the
terms under which SEMCO would purchase such increased Transportation Capacity.
If APC and SEMCO are unable to reach an agreement on the terms of the purchase
by SEMCO of such increased Transportation Capacity within ninety (90) days of
the original notice from APC, APC shall be free to offer such increased
Transportation Capacity to third parties. If following the sale by APC of
Transportation Capacity to a third party, the Yearly deliveries of Gas by SEMCO
to such third party is less than the Gas deliveries in the Year immediately
prior to the Year in which APC sold capacity to such third party (the "Base
Year"), SEMCO and ENSTAR shall be entitled to a credit for such Year to be
applied against the next payment amounts due hereunder and under the Special
Contract in an amount equal to the sum of the greater of the annual Demand
Charge payable pursuant to Article IV of this Agreement or Article VII of the
Special Contract multiplied by a fraction, the numerator of which is the lesser
of the Gas deliveries by APC to such third party during such Year or the
aggregate reduction in Gas deliveries to such third parties for such Year when
compared to the Base Year (the "Lost Volumes"), and the denominator of which is
the total Gas deliveries in the Base Year. Any terms negotiated between APC and
SEMCO for increased Transportation Capacity shall be subject to Commission
approval, if required.



                                       5
<PAGE>

                  (c) SEMCO, acting for ENSTAR, shall tender at the Receipt
Point(s) the volume of Gas which it desires APC to transport to the ENSTAR
System, which total volume shall not exceed the applicable Maximum Daily
Quantity. SEMCO shall be responsible for all arrangements (and associated costs
and expenses) necessary to make Gas available at the Receipt Point(s). SEMCO
shall use its best efforts to notify APC, or cause its suppliers to notify APC,
at least four (4) hours prior to terminating, curtailing or interrupting
deliveries to a Receipt Point.

         Section 3.2. APC's Rights and Obligations.

                  (a) APC shall make Transportation service available to SEMCO's
ENSTAR division, up to the Maximum Daily Quantity for any segment of APC System,
pursuant to the terms of this Agreement and the Special Agreement.

                  (b) APC shall receive at the Receipt Point(s) all Gas up to
the Maximum Daily Quantities tendered by SEMCO, acting through its ENSTAR
division, and shall deliver an equivalent volume of Gas to the Delivery Point(s)
designated by ENSTAR, less Gas used for compression, lost or otherwise
unaccounted for. APC shall never be obligated to deliver during any Day more Gas
than ENSTAR tenders for delivery during that Day. APC shall deliver Gas to
ENSTAR at the Delivery Point(s) at APC's prevailing line pressure as such
pressure may vary from time to time.

                                   ARTICLE IV

                              SPECIAL PAYMENT TERMS

         Section 4.1. Reservation Rate and Commodity Rate. For each Month during
the Base Term and any Renewal Term, SEMCO shall pay and APC shall accept as
payment for Transportation services provided in accordance with this Agreement
the sum of the following amounts, each computed by use of the rates set forth on
Exhibit D:

                  (a) the amount of the Reservation Rate set forth on Exhibit D
(the "Reservation Rate"); plus

                  (b) the amount, calculated by multiplying the Commodity Rate
set forth on Exhibit D (the "Commodity Rate") by the Delivered Gas for the
Month, as measured in accordance with the measurement provisions in Articles IV
and V of the Special Contract.

         Section 4.2. Credit for Amounts Paid under Special Contract. SEMCO
shall receive a credit against the Monthly amounts due to APC under Section 4.1
above in an amount equal to any amounts to be paid by its ENSTAR division
pursuant to the terms of the Special Contract.

         Section 4.3. Special Payment Agreement. SEMCO and APC recognize that
the Commission could, in the future, modify the rates or other terms in the
Special Contract. Nevertheless, in recognition of the fact that payment of the
amounts set forth in Section 4.1 above for the Base Term represent an essential
component of the consideration paid by Buyer for the acquisition of APC from
SEMCO, SEMCO agrees to pay to APC the amounts set forth in Section 4.1 above for
the Base Term (and any Renewal Term) even if the rates in the Special Contract
are later reduced or increased by the Commission and regardless of the extent to
which ENSTAR is permitted to continue to include such payments in the rates
charged to its customers. SEMCO will continue to receive a Monthly credit
provided for in Section 4.2 above in the amount of any revised payments under
the Special Contract.

         Section 4.4. Billing and Payment.

                  (a) Payment of the Reservation Rate for the Month in which the
Commencement Date occurs shall be due on the Commencement Date. Payment of the
Reservation Rate for each succeeding Month shall be due, without invoice, on the
first Business Day of such Month.

                  (b) With respect to amounts payable other than the Reservation
Rate, APC shall deliver to SEMCO a monthly statement for Transportation services
for the preceding Month, which shall detail all charges payable by SEMCO during
the preceding Month and the basis for the calculation of the amount due;
provided, however, that so long as the Reservation Rate and the Commodity Rate
under the Special Contract have not been modified, the statement delivered by
APC to ENSTAR pursuant to Article VII of the Special Contract shall satisfy the
requirements of this Section 4.4.2. SEMCO shall pay APC the full amount due by
wire transfer of immediately available funds to the account designated by APC no
later than ten (10) days after SEMCO's receipt of such statement.

                  (c) If SEMCO disagrees with any statement, it shall promptly
notify APC in writing of its disagreement and the facts providing the basis
therefore. If the Parties are unable to agree upon a settlement of the contested
portion of a statement, the dispute shall be addressed in accordance with
Article VI. The existence of a dispute with regard to any portion of a payment
due shall not relieve SEMCO of the obligation to pay any uncontested amounts due
under this Agreement or to perform any other obligation under this Agreement.
SEMCO shall pay, no later than ten (10) days after SEMCO's receipt of the
statement, any disputed amount into a separate interest bearing account at First
National Bank of Alaska or its successor and shall notify APC of such deposit.
Any interest which may accrue in such account shall be payable to the Party in
whose favor the dispute is resolved, and any such interest actually paid shall
reduce the interest payments required to be made pursuant to Section 4.4.5
accordingly.

                  (d) Each Party shall have the right during normal business
hours to examine the books, records and charts of the other Party to the extent
necessary to verify the accuracy of any invoice related to this Agreement.
Claims for adjustments on account of subsequently discovered errors must be made
within twelve (12) Months of the date the statement was issued. The Party
discovering such an error shall promptly notify the other Party in writing of
the errors believed in good faith to have occurred and the facts providing the
basis for such belief. Adjustment of overpayments or underpayments shall be made
within ten (10) days after resolution of such subsequently discovered errors.

                  (e) If either Party shall fail to make any payment required by
this Agreement when due, including contested portions of bills, or if any Party
makes an overpayment requiring a refund by the other Party, the amount due shall
bear interest, from the due date of the payment or the date on which the
overpayment was made until the date of payment, at a rate per annum for the
first ten (10) days equal to the rate published as the "prime rate" in The Wall
Street Journal for the first Business Day of the month in which such invoice is
due, plus 2%, and thereafter at a rate per annum equal to 15%, but in no event
at any rate that is greater than the maximum interest rate allowed by applicable
Laws. If the due date of any payment is not a Business Day, then the next
Business Day shall be the last day on which payment can be paid without interest
charges being assessed.

of such consequence as will impair such Party's ability to perform substantially

petition against it in such proceeding; or the appointment by a Party, without
the consent or acquiescence of the other Party, of any trustee, receiver, or
liquidator of the Party or of any material part of its properties, if within

         Section 5.2. Notice and Opportunity To Cure. If a Party claims that an
Event of Default has occurred, such Party shall provide the defaulting Party
with written notice thereof, specifying the claim of breach and the basis of
such claim. Except for any Event of Default described in Section 5.1.4, the
alleged defaulting Party shall have a period of thirty (30) days (ten (10) days
in the case of a payment default) after receipt of notice, to cure such alleged
Event of Default. If any non-payment default (other than a default described in
Section 5.1.4) cannot be reasonably cured within such thirty (30) day period,
the cure period shall be extended by an additional thirty (30) days, so long as
the defaulting Party diligently pursues efforts to cure the default and the
non-defaulting Party is paid any actual and direct damages for any injury
sustained as a result of such default continuing during the extended cure
period.

         Section 5.3. Remedies.

                  (a) APC shall have the right to terminate this Agreement upon
a default by SEMCO that has not been cured within the cure period therefore

damages as are available at law and equity, subject to Section 7.5.

                  (b) In the case of a default by APC that has not been cured
within the cure period therefor, SEMCO shall have the option to either terminate
this Agreement or to operate and maintain the APC System in order to receive
Transportation service and to make payments pursuant to the terms of this
Agreement. SEMCO shall notify APC at least five (5) days before the expiration
of the cure period that it intends to exercise its option to operate and
maintain the APC System upon expiration of the cure period. Upon exercise of
SEMCO's option to operate and maintain the APC System or terminate this
Agreement, SEMCO shall be entitled to such damages as are available at law and
equity, subject to Section 7.5. If SEMCO pursues its option to operate and
maintain the APC System, (a) SEMCO's payments under this Agreement shall be
offset by the amount of actual operation and maintenance costs incurred by SEMCO
to operate and maintain the APC System if the O&M Agreement has been terminated,
and (b) upon the cure by APC of such default, SEMCO shall cease to operate and
maintain the APC System pursuant to this Section.

         Section 5.4. Election of Remedies. The termination of this Agreement or
exercise of SEMCO's option to operate and maintain the APC System shall not
excuse either Party from obligations which may have accrued under this Agreement
prior to such termination or exercise.

Party who will attend the meeting with complete power to resolve the dispute.

<PAGE>

                  (c) If the meeting fails to resolve the dispute by a signed
agreement among the officers, either Party may submit the dispute for binding
arbitration administered by the American Arbitration Association ("AAA") under
its Commercial Arbitration Rules before a single arbitrator, and judgment on the
award rendered by the arbitrator may be entered in any court having jurisdiction
thereof.

                  (d) The Parties agree to make discovery and disclosure of all
matters relevant to the dispute to the extent and in the manner provided by the
Federal Rules of Civil Procedure. The arbitrator will rule on all requests for
discovery and disclosure and discovery shall be completed within 60 days after
the date of selection of the arbitrator. The arbitrator may consider any matter
relevant to the subject to the dispute and shall follow the statutes and
decisions of the substantive law of Alaska relevant to the subject. The
arbitrator shall not have the authority or power to alter, amend or modify any
of the terms and conditions of this Agreement. The arbitrator shall issue a
final ruling within 150 days after the date of selection of the arbitrator.

signed and shall be final and binding upon the Parties. The fees and expenses of
counsel, witnesses and employees of the Parties and all other costs and expenses
incurred exclusively for the benefit of the Party incurring the same shall be
borne by the Party incurring such fees and expenses. All other fees and expenses
including compensation for the arbitrator, shall be divided equally between the
Parties. All meetings and arbitrations held pursuant to this Section 6.1 shall
take place in Anchorage, Alaska.

                          INDEMNIFICATION AND INSURANCE

         Section 7.1. Indemnification. Each Party shall indemnify, hold harmless
and defend the other Party, its affiliates, successors and assigns and their
respective agents, officers, directors, managers, employees, representatives and
affiliates, against all claims, demands, losses, judgments, damages and
associated costs and expenses (including reasonable fees, disbursements and
expenses for attorneys and experts incurred by the indemnified Party in any
actions or proceedings between the indemnified Party and a third party), related
to property damage, personal injuries or death suffered by third persons
resulting from any act or failure to act by such indemnifying Party related to
this Agreement, or from the undertaking by such Party of any activity
contemplated by this Agreement, regardless of whether attributable in whole or
in part to any act, omission, negligence (active, passive, sole, joint or
concurrent with that of the indemnified Party or any other person), strict
liability, any condition or defect on or in any property, or other fault or
responsibility of the indemnified Party or any other person or party (whether
such liability is based on contract, warranty, tort, statute or otherwise),
except that if the property damage, personal injuries or death are caused in
part, but not entirely, by the indemnified Party then the indemnifying Party
shall be obligated under this Section 7.1 only to the extent of the percentage
of fault attributed to such indemnifying Party and/or its agents, officers,
directors, managers, employees, representatives and affiliates. The indemnities
provided in this Section shall be the sole and exclusive remedy of the
indemnified Party with respect to all matters related to property damage,
personal injuries or death resulting from any act or failure to act by an
indemnifying Party related to this Agreement.

         Section 7.2. Notice. If a Party becomes aware of any event or
circumstance which might give rise to indemnification under this Agreement, it
shall provide the other Party with written notification within the earlier of
thirty (30) days after discovery of the event or circumstance or ten (10) days
prior to the time any response regarding such event or circumstances is required
by law to be made.

         Section 7.3. Defense of Legal Actions. At the indemnified Party's
request, the indemnifying Party shall defend any suit asserting a claim covered
by this indemnity and shall pay all costs and expenses (including reasonable
fees, disbursements and expenses for attorneys and experts) that may be incurred
in enforcing this indemnity. The indemnified Party may, at its own expense,
retain separate counsel and participate in the defense of any such suit or
action. The indemnifying Party shall not compromise or settle a claim hereunder
without the prior written consent of the indemnified Party, provided, however,
that if such consent is withheld then the liability of the indemnifying Party
shall be limited to the aggregate of the amount of the proposed settlement or
compromise, the amount of fees, disbursements and expenses for attorneys and
experts outstanding at the time such consent shall have been withheld, and the
amount of any outstanding claim against which the indemnification applies and
which is not covered by the proposed settlement or compromise (together with all
costs and expenses associated with such outstanding claim). Thereafter, the
indemnified Party shall hold harmless and reimburse the indemnifying Party, upon
demand, for the amount of any additional liability, fees, disbursements and
expenses for attorneys and experts incurred by the indemnifying Party in excess
of the amounts described above after such consent shall have been withheld.

         Section 7.4. Survival. Each Party's indemnification and defense of
action obligations hereunder for acts or occurrences prior to the expiration or
termination of this Agreement shall continue in full force and effect regardless
of the expiration or termination of this Agreement. Such obligations shall not
be limited in any way by any limitation on insurance, by the amount or types of
damages, or by any compensation or benefits payable by the Parties under
worker's compensation acts, disability benefit acts or other employee acts.

         Section 7.5. Limitation on Damages. NEITHER PARTY SHALL BE LIABLE TO
THE OTHER PARTY FOR INCIDENTAL, PUNITIVE, SPECIAL, INDIRECT, OR CONSEQUENTIAL
DAMAGES CONNECTED WITH OR RESULTING FROM PERFORMANCE OR NON-PERFORMANCE OF THIS
AGREEMENT OR ANY ACTION UNDERTAKEN IN CONNECTION WITH, OR RELATED TO THIS
AGREEMENT, INCLUDING ANY SUCH DAMAGES WHICH ARE BASED UPON CAUSES OF ACTION FOR
BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE AND MISREPRESENTATION), BREACH OF
WARRANTY OR STRICT LIABILITY. Notwithstanding the foregoing, if a Party is held
liable to a third party for any such damages and the other Party is obligated to
provide indemnity for the matter that gave rise to such damages, such indemnity
shall obligate the indemnifying Party to pay such damages.

                         Confidentiality of Information

         Section 7.1. General. As used in this Article VII, "Confidential
Information" shall mean any information not in the public domain or generally
known in the industry, in any form relating to the business and operations of
Owner or Operator (each such entity, for purposes of this Article VII, a
"Company"), including but not limited to information regarding customers,
vendors, suppliers, trade secrets, training programs, manuals or materials,
technical information, contracts, systems, procedures, mailing lists, know-how,
trade names, improvements, price lists, financial or other data (including the
revenues, costs or profits associated with any of such Company's services),
business plans, code books, invoices and other financial statements, computer
programs, software systems, databases, disks and printouts, plans (business,
technical or otherwise), customer and industry lists, correspondence, internal
reports, personnel files, sales and advertising material, telephone numbers,
names, addresses or any other compilation of information, written or unwritten,
which is or was used by such Company, regardless of whether such information was
or is owned during the term of this Agreement by such Company.

         Section 7.2. Operator's Obligations. Operator shall maintain the
confidentiality of any Confidential Information of Owner acquired by Operator
during the term of this Agreement, and except as otherwise provided in this
Agreement, shall not use such Confidential Information for any purpose other
than the performance of this Agreement and the performance of services under the
O&M Agreement; provided, however, Operator may use any Confidential Information
in the resolution of any disputes under this Agreement. Upon termination of this
Agreement, except as otherwise provided in this Agreement, Operator agrees to
turn over such Confidential Information to Owner or to destroy such Confidential
Information, but only in accordance with the instructions of Owner; provided,
however, that Operator may maintain one archive copy of all of such Confidential
Information in a secure data storage facility.

         Section 7.3. Owner's Obligations. Owner shall maintain the
confidentiality of any Confidential Information of Operator acquired by Owner
during the term of this Agreement, and except as otherwise provided in this

invoices and other similar financial information concerning the cost of Gas
Control Services to any prospective purchaser of Operator or the Transmission
Business, and may use any Confidential Information in the resolution of any
disputes under this Agreement. Upon termination of this Agreement, except as
otherwise provided in this Agreement, Owner agrees to turn over such
Confidential Information to Operator or to destroy such Confidential Information

         Section 7.4. Compulsory Disclosure. If any Company is requested or
required to disclose Confidential Information of another unaffiliated Company
pursuant to any judicial or administrative process, law, regulation or statute,
then such receiving Company shall promptly notify the other unaffiliated Company
to this Agreement in writing of such request or requirement. The Company whose
Confidential Information is requested or required to be disclosed shall either
(i) promptly seek protective relief from such disclosure obligation or (ii)
direct the receiving Company to comply with such request or requirement. If,
after a reasonable opportunity to seek protective relief, such relief is not
obtained by the Company whose Confidential Information is subject to discovery
or disclosure, or if such Company fails to obtain such relief, the receiving
Company may disclose such portion of such Confidential Information that such
Company reasonably believes it is legally obligated to disclose.

         Section 7.5. Injunction. Each Company agrees that the breach by another
unaffiliated Company of its obligations under this Article VII would cause
significant and irreparable harm to the aggrieved Company, which may be
difficult to measure with certainty or to compensate through money damages. Each
Company acknowledges that the aggrieved Company shall be entitled, without proof
of irreparable harm and without waiving any other right or remedy available to
it, to such injunctive and equitable relief as may be deemed proper by a court
of competent jurisdiction.

                        Relationship BETWEEN the Parties

         Section 8.1. No Joint Venture. It is the intent of the Parties that
with respect to the provision of the Services pursuant to this Agreement, Owner
and Operator are independent contractors. Except to the extent Operator executes
contracts or documents as the agent of Owner pursuant to the terms of Section
16.1, nothing in this Agreement shall cause the relationship between Operator
and Owner to be deemed to constitute an agency, partnership or joint venture.
The terms of this Agreement are not intended to constitute a joint employer for
any purpose between any of the Parties and their affiliates. Each of the Parties
agrees that the provisions of this Agreement as a whole are not intended to, and
do not, constitute control of the other Party (or any affiliates thereof) or
provide it with the ability to control such other Party (or any affiliates
thereof), and each Party hereto expressly disclaims any right or power under
this Agreement to exercise any power whatsoever over the management or policies
of the other (or any affiliates thereof). Nothing in this Agreement shall oblige
either Party hereto to act in breach of the requirements of applicable Laws or
Governmental Approvals.

                                   ARTICLE IX

                  Indemnification; Release; Limit on Liability

         Section 9.1. Indemnification by Operator. Operator shall indemnify,
defend and hold harmless Owner, and each of its officers, directors, employees,
agents, and affiliates (and the officers, directors, employees and agents of
such affiliates) ("Owner Indemnified Party") if any such Owner Indemnified Party
shall at any time or from time to time suffer any damage, judgment, fine,
penalty, demand, settlement, liability, loss, cost, expense (including
reasonable attorneys', consultants' and experts' fees), claim or cause of action
(each, a "Loss") arising out of, relating to or resulting from the Operator's
performance of this Agreement, to the extent such Loss results from any breach
of this Agreement or the fault, tortuous act, negligence, strict liability,
gross negligence or willful misconduct of Operator. Further, Operator shall
indemnify and hold Owner harmless and defend Owner from any and all claims,
costs, damages, injuries, demands and causes of action commenced by an employee
of Operator (or his or her estate or legal representative) which arises directly
or indirectly from the performance of Services except to the extent that such
Loss directly results from the gross negligence or willful misconduct of Owner.

         Section 9.2. Indemnification by Owner. Owner shall indemnify, defend
and hold harmless Operator, and each of its officers, directors, employees,
agents, and affiliates (and the officers, directors, employees and agents of
such affiliates) ("Operator Indemnified Party") if any such Operator Indemnified
Party shall at any time or from time to time suffer any Loss arising out of,
relating to or resulting from Owner's performance of this Agreement, to the
extent such Loss results from any breach of this Agreement or the fault,
tortuous act, negligence, strict liability, gross negligence or willful
misconduct of Owner. Further, Owner shall indemnify and hold Operator harmless
and defend Operator from any and all claims, costs, damages, injuries, demands
and causes of action commenced by an employee of Owner (or his or her estate or
legal representative), except to the extent that (i) such Loss directly results
from the gross negligence or willful misconduct of Operator, or (ii) Owner is
entitled to indemnity from Operator under Section 13.1.

         Section 9.3. Procedures. Any Party asserting a claim for
indemnification hereunder (such Party seeking indemnification, the "Indemnified
Party") shall notify the other Party (the "Indemnifying Party") (with reasonable
specificity) promptly after it becomes aware of facts supporting a claim or
action for indemnification under this Article IX, and shall provide to the
Indemnifying Party as soon as practicable thereafter all information and
documentation reasonably necessary to support and verify any Losses associated
with such claim or action. The failure to so notify or provide information to
the Indemnifying Party shall not relieve the Indemnifying Party of any liability
that it may have to any Indemnified Party, except to the extent that the
Indemnifying Party demonstrates that it has been materially prejudiced by the
Indemnified Party's failure to give such notice, in which case the Indemnifying
Party shall be relieved from its obligations hereunder to the extent of such
material prejudice. The Indemnifying Party may, and, at the request of the
Indemnified Party, shall participate in and defend, contest or otherwise protect
the Indemnified Party against any such claim or action by counsel of the
Indemnifying Party's choice at its sole cost and expense; provided, however,
that the Indemnifying Party shall not make any settlement or compromise without
the prior written consent of the Indemnified Party (which consent shall not be
unreasonably withheld, conditioned or delayed) unless the sole relief provided
is monetary damages that are paid in full by the Indemnifying Party. The
Indemnified Party shall have the right, but not the obligation, to participate
at its own expense in the defense thereof by counsel of the Indemnified Party's
choice and shall in any event use its reasonable best efforts to cooperate with
and assist the Indemnifying Party. If the Indemnifying Party fails timely to
defend, contest or otherwise protect against such suit, action, investigation,
claim or proceeding, the Indemnified Party shall have the right to do so,
including, without limitation, the right to make any compromise or settlement
thereof, and the Indemnified Party shall be entitled to recover the entire cost
thereof from the Indemnifying Party, including, without limitation, reasonable
attorneys' fees, disbursements and amounts paid as the result of such suit,
action, investigation, claim or proceeding.

made by wire transfer of immediately available funds to such account or accounts
as the Indemnified Party shall designate to the Indemnifying Party in writing.

         Section 9.5. Survival. The provisions of this Article IX shall survive
the termination of this Agreement for claims made within a period of three (3)
years after the expiration date of the Service Term.

         Section 9.6. Release and Limit on Liability. Operator shall not be
liable to Owner for, and Owner hereby releases Operator and its affiliates, and
each officer, director, employee and agent of Operator and/or any of its
affiliates (the "Operator Parties") from, any Loss arising from any act or
omission of Operator in connection with the Gas Control Services, except to the
extent any such Loss results from an event for which Owner is entitled to
indemnification under Section 9.1. Owner shall not be liable to Operator for,
and Operator hereby releases Owner and its affiliates, and each officer,
director, employee and agent of Owner and/or any of its affiliates (the "Owner
Parties") from, any Loss arising from any act or omission of Owner in connection
with the Services, except to the extent any such Loss results from an event for
which Operator is entitled to indemnification under Section 9.2. Notwithstanding
anything in this Agreement to the contrary, the aggregate liability of the
Operator Parties under this Agreement shall not exceed the sum of (i) the
aggregate amount of payments received by Operator pursuant to Section 5.1
hereof, and (ii) any payments actually received by Operator or paid to any third
party on behalf of Operator in respect to such liabilities under policies of
insurance. IN NO EVENT SHALL ANY OF THE OPERATOR PARTIES BE LIABLE TO ANY OF THE
OWNER PARTIES, NOR SHALL ANY OF THE OWNER PARTIES BE LIABLE TO ANY OF THE
OPERATOR PARTIES, FOR SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE
LOSS, DAMAGES OR EXPENSES (INCLUDING LOST PROFITS OR SAVINGS) ARISING FROM THIS
AGREEMENT.

a transfer of a Party's rights and obligations hereunder by acquisition of
substantially all of the assets of such Party, merger or operation of law, but
if any such transfer is made by Operator without Owner's prior written consent,
Owner shall have the right to terminate this Agreement and neither Party shall

         Section 11.10. Negotiated Agreement. This Agreement has been negotiated
by the Parties and the fact that the initial and final draft will have been

any party to this Agreement or be used in any respect or forum in the
construction or interpretation of this Agreement or any of its provisions.

         Section 11.11. Waiver. No consent or waiver, express or implied, by any
Party to or of any breach or default by any other Party in the performance by

obligations hereunder by such other Party hereunder. Failure on the part of any
Party to complain of any act or failure to act of any other Party or to declare
any other Party in default, irrespective of how long such failure continues,
shall not constitute a waiver by such first Party of any of its rights
hereunder.

         Section 11.12. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable, each Party directs that such court interpret and
apply the remainder of this Agreement in the manner that it determines most
closely effectuates the Parties' intent in entering into this Agreement, and in
doing so particularly take into account the relative importance of the term,
provision, covenant or restriction being held invalid, void or unenforceable.

<PAGE>

         4.       WARRANTY OF TITLE AND QUIET ENJOYMENT; SUBORDINATION -
                  Licensor warrants that (a) Licensor owns and operates the
                  Facilities, (b) the use of this License by Licensee in
                  accordance with the terms hereof will not breach, violate or
                  infringe on the rights of any third parties, and (c) Licensor

                  Licensee's payment of the License Fee and otherwise complying
                  with the terms hereof, Licensor shall ensure that Licensee may
                  have quiet use and enjoyment of the Facilities. Subject to the
                  foregoing, this License shall be subordinate and inferior to
                  any mortgage or lien which currently encumbers the Facilities.
                  Licensee further agrees to subordinate this License to any
                  future mortgage or deed of trust that Licensor, its successors
                  and assigns, obtains against the Facilities, provided that
                  Licensor obtains a non-disturbance agreement reasonably
                  acceptable to Licensee from the holder of any such mortgage or
                  deed of trust.

         5.       COVENANTS AND AGREEMENTS-

                  (a) Licensor, at Licensor's sole cost and expense, shall
                      maintain the Facilities in good order and repair

                      past practices, reasonable wear and tear, damage by fire,
                      the elements or other casualty excepted. Licensor shall be
                      under no obligation to improve or expand the Facilities to
                      accommodate Licensee's System. Damage to the Facilities or
                      the equipment or improvements of Licensor, which results
                      from the acts or omissions of Licensee, shall be repaired
                      by Licensee at Licensee's cost and expense, or at the
                      option of Licensor, Licensee shall reimburse Licensor for
                      the actual costs incurred by Licensor in repairing such
                      damage or replacing such equipment or improvements, as
                      evidenced by adequate documentation. Damage to the
                      equipment or improvements of Licensee, which results from
                      the acts or omissions of Licensor, shall be repaired by
                      Licensor at Licensor's cost and expense, or at the option
                      of Licensee, Licensor shall reimburse Licensee for the
                      actual costs incurred by Licensee in repairing such damage
                      or replacing such equipment or improvements, as evidenced
                      by adequate documentation.

                  (b) Licensor shall not enter into any agreement to sell or
                      otherwise transfer ownership of all or any part of the
                      Facilities unless the purchaser agrees to be bound by and
                      be subject to the terms of this License.

                  (c) Licensee will use the Facilities solely in connection with
                      its operation of the System and in a manner that will not
                      unreasonably disturb the occupancy of Licensor or any
                      other licensees of the Facilities or the sites where the
                      Facilities are located. Licensee agrees that it will not
                      install any equipment of types and radio frequencies which
                      would cause interference to communications operations
                      being conducted from the Facilities by Licensor. Licensee
                      also covenants that any equipment installed by Licensee
                      shall comply with all applicable laws, ordinances and
                      regulations, including but not limited to those
                      regulations promulgated by the FCC. In the event the
                      equipment installed by Licensee causes such interference,
                      Licensee will promptly after notice from Licensor take the
                      steps necessary to correct and eliminate the interference.
                      If such interference cannot be eliminated within
                      forty-eight (48) hours after receipt by Licensee of notice
                      from Licensor describing the existence of the
                      interference, Licensee shall temporarily disconnect the
                      electric power and shut down the equipment (except for
                      intermittent operation for the purpose of testing, after
                      performing maintenance, repair, modification, replacement,
                      or other action taken for the purpose of correcting such
                      interference) until such interference is corrected. If
                      such interference is not corrected within thirty (30) days
                      after receipt by Licensee of such prior written notice
                      from Licensor of the existence of interference, Licensee
                      agrees to then remove the equipment causing such
                      interference from the Facilities. Licensor shall impose
                      upon future licensees a duty to refrain from interfering
                      with Licensee which is similar to that set forth herein
                      and Licensee covenants that it shall not subsequently
                      modify its equipment at the Facilities in a way which
                      causes interference with other then existing equipment at
                      the Facilities.

         6.       UTILITIES - Except as provided herein, Licensor shall pay
                  utility services relating to the Facilities. Any utility
                  services installed on the Facilities for the use or benefit of
                  Licensee shall be made at the sole cost and expense of
                  Licensee and shall be separately metered from Licensor's
                  utilities. Notwithstanding the foregoing, to the extent
                  utility facilities can be shared by multiple licensees of the
                  Facilities, Licensor agrees to use its best efforts to
                  allocate the construction and installation costs of common
                  utility facilities equally between the licensees that have
                  executed license agreements as of the time construction and
                  installation of the utility facilities commences. The Parties
                  acknowledge and agree that the provisions of this Section 6 do
                  not apply with respect to services, including the use of the
                  Facilities, provided by Licensor pursuant to the terms of the
                  Operations and Maintenance and Administration Services
                  Agreement of even date herewith between Licensor and Licensee,
                  as such agreement may be amended, supplemented or replaced
                  from time to time.

         7.       TAXES - Except as provided herein, Licensor shall pay all real
                  property taxes relating to the Facilities. Licensee shall pay
                  any and all property, use or other taxes associated with any
                  expansion of the Facilities made exclusively for Licensee's
                  use.

         8.       TOWER MARKING AND LIGHTING REQUIREMENTS - Licensor shall be
                  responsible for compliance with any applicable marking and
                  lighting requirements of the FAA and the FCC, provided that if
                  the requirement for compliance results from the presence of
                  equipment of the Licensee, then Licensee shall pay costs and
                  expenses therefor (including any lighting automated alarm
                  system so required).

         9.       MECHANICS' LIENS - Licensee shall not permit any mechanics,'
                  materialmen's, contractors' or subcontractors' liens arising
                  from any construction work, repair, restoration or removal or
                  any other claims or demands to be enforced against the
                  Facilities or any part thereof. Licensor shall have the right
                  at any time to post and maintain upon the Facilities such
                  notices as may be necessary to protect Licensor against
                  liability for all such liens and encumbrances. Licensee shall
                  give Licensor written notice prior to the commencement of any
                  work or the delivery of any materials connected with such work
                  or construction, repair, restoration, or removal of materials
                  on the Facilities. Licensor shall assume no liability for the
                  payment of materials or labor which accrue in the installation
                  of Licensee's improvements upon the Facilities and no
                  mechanics' or materialmen's lien for Licensee's improvements
                  shall attach to the interest of Licensor in the Facilities.

         10.      FINANCING AGREEMENT - Licensee may, upon written notice to
                  Licensor, mortgage or grant a security interest in any
                  equipment it installs on the Facilities to any such mortgagees
                  or holders of security interests including their successors
                  and assigns (hereinafter collectively referred to as "Secured
                  Parties"). No such security interest shall extend in any way
                  to the interests or property of Licensor or any other licensee
                  of the Facilities.

         11.      DISCLAIMER OF WARRANTIES - LICENSEE ACKNOWLEDGES THAT, EXCEPT
                  AS SET FORTH IN SECTION 4, LICENSOR HAS NOT MADE ANY
                  REPRESENTATION OR WARRANTY, EXPRESS, IMPLIED OR AT COMMON LAW,
                  BY STATUTE, OR OTHERWISE RELATING TO ANY FACILITIES INCLUDING,
                  WITHOUT LIMITATION, THE CONDITION OF THE TOWER FACILITIES
                  (INCLUDING, WITHOUT LIMITATION, ANY IMPLIED OR EXPRESSED

                  CONFORMITY TO MODELS OR SAMPLES OF MATERIALS, ENVIRONMENTAL

                  FOREGOING, LICENSOR HEREBY EXPRESSLY DISCLAIMS AND NEGATES,
                  AND LICENSEE HEREBY WAIVES (I) ANY IMPLIED OR EXPRESSED
                  WARRANTY OF MERCHANTABILITY; (II) ANY IMPLIED OR EXPRESSED
                  WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, (III) ANY
                  IMPLIED OR EXPRESSED WARRANTY OF CONFORMITY TO MODELS OR
                  SAMPLES OF MATERIALS; (IV) ANY CLAIM FOR DAMAGES BECAUSE OF
                  ANY LATENT OR PATENT DEFECTS OR OTHER DEFECTS, WHETHER KNOWN
                  OR UNKNOWN AND (V) ANY AND ALL IMPLIED WARRANTIES EXISTING
                  UNDER APPLICABLE LAW. IT IS THE EXPRESS INTENTION OF THE
                  PARTIES HERETO THAT ALL TOWER FACILITIES BE LICENSED ON AN AS
                  IS, WHERE IS BASIS. THE PARTIES HERETO AGREE THAT, TO THE
                  EXTENT REQUIRED BY APPLICABLE LAW TO BE EFFECTIVE, THE

                  ARE CONSPICUOUS DISCLAIMERS.

                  reasonably necessary to permit Licensee to complete a cure so
                  long as Licensee commences the cure within such thirty (30)
                  day cure period and thereafter continuously and diligently
                  pursues and completes such cure) shall be considered to be a
                  default of this License by Licensee.

         15.      REMEDIES - In the event of a default by Licensee under the
                  terms of Section 14 of this License and after the Licensee's
                  failure to cure such default within the time allowed the
                  Licensee to cure such default, then this License shall
                  automatically terminate, and Licensor may remove any of
                  Licensee's equipment at the Facilities without being deemed
                  liable for trespass or conversion and store the same at
                  Licensee's sole cost and expense.

         16.      NOTICES - All notices or demands by or from Licensor to
                  Licensee, or Licensee to Licensor, shall be in writing.
                  Notices shall be effective on the day they are sent. Such
                  notices or demands shall be mailed (U.S. mail, certified with
                  return receipt requested or by overnight courier service) to
                  the other party at the following address:

                  relocate the Facilities to, or replace the Facilities in,
                  alternative locations or properties owned or leased by
                  Licensor. Such relocations will (i) be at Licensor's sole
                  cost; and (ii) not result in an interruption of Licensee's
                  communications services. Upon such relocation, the Facilities
                  covered herein shall be the relocated or replaced Facilities.
                  At the request of either party, Licensor and Licensee shall
                  enter into an amendment of this License to clarify the rights
                  of Licensee to the relocated or replaced Facilities.

                  between the parties hereto with respect to the use of the
                  Facilities and supersedes all previous negotiations leading
                  thereto. This License may be modified only by an agreement in
                  writing executed by Licensor and Licensee.

         19.      SUCCESSORS AND ASSIGNS - This License shall be binding upon
                  and inure to the benefit of the legal representatives, heirs,
                  successors, and assigns of Licensor and Licensee. Licensee may
                  not sublicense all or any part of the Facilities without
                  Licensor's prior written consent. Licensee may assign all of
                  its rights hereunder to any party acquiring Licensee's
                  interest in the System provided such party agrees to bound and
                  subject to the terms of this License. Licensor may assign its
                  rights hereunder to any party who owns the Facilities and
                  agrees to be bound and subject to the terms of this License.

         20.      LIMITATION OF PARTIES' LIABILITY - Neither Licensor nor
                  Licensee shall be responsible for any incidental or
                  consequential damages incurred resulting from (i) Licensor's
                  or Licensee's use or inability to use the Facilities, or (ii)
                  damage to the other's equipment.

         21.      MISCELLANEOUS - (a) This License is governed by the laws of
                  the State of Alaska; (b) If any provision of this License is
                  invalid or unenforceable with respect to any party, the
                  remainder of this License will not be affected and each
                  provision of this License will be valid and enforceable to the
                  fullest extent permitted by law; (c) The prevailing party in
                  any court action or mutually agreed upon arbitration
                  proceeding to enforce the terms of this License is entitled to
                  receive its reasonable attorneys' fees and other reasonable
                  expenses from the non-prevailing party; (d) Failure or delay
                  on the part of either party to exercise any right, power or
                  privilege hereunder will not operate as a waiver thereof and
                  waiver or breach of any provision hereof under any
                  circumstances will not constitute a waiver of any subsequent
                  breach; (e) Each party executing this License acknowledges
                  that it has full power and authority to do so and that the
                  person executing on its behalf has the authority to bind the
                  party; (f) Neither party shall be deemed the drafter of this
                  License for purposes of any applicable judicial principles or
                  rules of contract construction.

         Section 2.4. Recordable Documents. At the request of either Party, a
counterpart of this Agreement in recordable form shall be placed of record in
the real estate records in any jurisdiction in which any Affected Right of Way
is located.

         Section 2.5. Modifications to Schedules. The Parties agree to update
Schedules 2.1 and 2.2 from time to time to correct any errors contained therein
and to add any Affected Rights of Way not listed on such Schedules.

                                  ARTICLE III

                        JOINT USE RIGHTS AND OBLIGATIONS

         Section 3.1. Maintenance and Repair Obligations. Each Party shall at
its own expense (i) conduct its operations in any Affected Right of Way,
including operation of its Facilities located in any Affected Right of Way, in
compliance with applicable Law, (ii) maintain and repair, in structurally and
operationally safe condition, its Facilities located on the Affected Rights of
Way, (iii) maintain such portions, if any, of the Affected Rights of Way as are
exclusively used, occupied and controlled by such Party, and (iv) with
reasonable promptness cause all damage to the lands underlying the Affected
Rights of Way or the other Party's Facilities resulting from activities
associated with the Permitted Uses undertaken by such Party to be repaired to a
condition at least substantially equivalent to that existing prior thereto
including, as appropriate, leveling of the surface thereof and seeding with
grasses or other ground cover as appropriate following excavation (it being
understood that the reasonable time for performance of certain restoration work,
such as reseeding, may depend on weather or seasonal considerations).

         Section 3.2. Additions/Alterations. This Agreement gives each Party the
right, in its discretion, to alter, improve, relocate or construct additional
Facilities on its Easement (an "Improvement"). A Party desiring to make an
Improvement shall notify the other party at least ten (10) days before
commencing work on the Improvement, and shall include in such notice plans,
specifications, surveys and/or other information pertaining to the proposed
Improvement so as to fully inform the other Party as to the nature and extent
thereof. Improvements shall be subject to all terms and conditions of this
Agreement. All Improvements shall be constructed in compliance in all material
respects with applicable Laws and the underlying Rights of Way, and otherwise in
a good and workmanlike manner. The Party constructing any Improvement shall be
responsible for ensuring that the Improvement does not violate any of the terms
and conditions of this Agreement or exceed the scope of the Easement on which
such Improvement is constructed.

                                       4
<PAGE>

         Section 3.3. Avoiding Endangerment. The Party on whose Affected Right
of Way an Improvement is to be constructed may notify the other Party in writing
within ten (10) days after receipt of notice of the Improvement of reasonable
work and design restrictions and precautions that are needed to avoid
endangering such Party's Facilities located on the Affected Right of Way, and
the Party undertaking the Improvement shall comply with all such restrictions
and precautions. Such restrictions and precautions may include, by way of
example and not limitation, restrictions and precautions that must be following
in the event that any pipeline or buried cable is to be uncovered, or for
installation of facilities that will cross pipelines or buried cables or will be
in close proximity to pipelines or buried cables. Neither the content of any
such work or design restrictions or precautions, nor the failure to specify such
restrictions or precautions, nor any failure to enforce to any extent any such
work or design restrictions or precautions shall limit or affect in any way the
obligations and liabilities of the Party undertaking the Improvements under this
Agreement.

         Section 3.4. Conflicting Uses. The Parties recognize that the use of an
Affected Right of Way by one Party may preclude or limit the right of the other
Party to use the Affected Right of Way. The Parties agree to cooperate with each
other and to use commercially reasonable efforts to minimize the likelihood of
conflicting uses. In the event that a Party's Facilities in an Affected Right of
Way limits or precludes a Permitted Use of the Affect Right of Way by the other
Party, the Party whose Permitted Use is limited or precluded (the "Limited
Party") shall have the right to cause the other Party (the "Limiting Party") to
relocate its Facilities located on the Affected Right of Way, subject to the
following:

                  (a) In no event shall any Facilities of the Limiting Party be
relocated if such relocation (i) unreasonably interferes with the Limiting
Party's normal business operations, or (ii) is to a location that increases the
Limiting Party's costs of operation or in which the Limiting Party has rights
that are less extensive or secure as such Party's property rights in the
Affected Right of Way.

                  (b) The Limited Party shall pay all of the costs and expenses
of the Limiting Party in relocating its Facilities, including, without
limitation, costs of alternative rights of way, design, engineering, permitting
and surveying costs and costs of construction of the replacement Facilities.

                  Section 3.5. Abandonment. Before abandoning any Affected Right
of Way, the Party holding such Affected Right of Way shall offer to transfer the
Affected Right of Way to the other Party, without cost other than reimbursement
of reasonable out-of-pocket transaction costs.

                                   ARTICLE IV

                  INDEMNIFICATION; RELEASE; LIMIT ON LIABILITY

         Section 4.1. Indemnification by APC. APC shall indemnify, defend and
hold harmless ENSTAR, and each of its officers, directors, employees, agents,
and affiliates (and the officers, directors, employees and agents of such
affiliates) ("ENSTAR Indemnified Party") if any such ENSTAR Indemnified Party
shall at any time or from time to time suffer any damage, judgment, fine,
penalty, demand, settlement, liability, loss, cost, expense (including
reasonable attorneys', consultants' and experts' fees), claim or cause of action
(each, a "Loss") arising out of, relating to or resulting from the APC's
performance of this Agreement, to the extent such Loss results from any breach
of this Agreement or the fault, tortuous act, negligence, strict liability,
gross negligence or willful misconduct of APC.

         Section 4.2. Indemnification by ENSTAR. ENSTAR shall indemnify, defend
and hold harmless APC, and each of its officers, directors, employees, agents,
and affiliates (and the officers, directors, employees and agents of such
affiliates) ("APC Indemnified Party") if any such APC Indemnified Party shall at
any time or from time to time suffer any Loss arising out of, relating to or
resulting from ENSTAR's performance of this Agreement, to the extent such Loss
results from any breach of this Agreement or the fault, tortuous act,
negligence, strict liability, gross negligence or willful misconduct of ENSTAR.

         Section 4.3. Procedures. Any Party asserting a claim for
indemnification hereunder (such Party seeking indemnification, the "Indemnified
Party") shall notify the other Party (the "Indemnifying Party") (with reasonable
specificity) promptly after it becomes aware of facts supporting a claim or
action for indemnification under this Article IV, and shall provide to the
Indemnifying Party as soon as practicable thereafter all information and
documentation reasonably necessary to support and verify any Losses associated
with such claim or action. The failure to so notify or provide information to
the Indemnifying Party shall not relieve the Indemnifying Party of any liability
that it may have to any Indemnified Party, except to the extent that the
Indemnifying Party demonstrates that it has been materially prejudiced by the
Indemnified Party's failure to give such notice, in which case the Indemnifying
Party shall be relieved from its obligations hereunder to the extent of such
material prejudice. The Indemnifying Party may, and, at the request of the
Indemnified Party, shall participate in and defend, contest or otherwise protect
the Indemnified Party against any such claim or action by counsel of the
Indemnifying Party's choice at its sole cost and expense; provided, however,
that the Indemnifying Party shall not make any settlement or compromise without
the prior written consent of the Indemnified Party (which consent shall not be
unreasonably withheld or delayed) unless the sole relief provided is monetary
damages that are paid in full by the Indemnifying Party. The Indemnified Party
shall have the right, but not the obligation, to participate at its own expense
in the defense thereof by counsel of the Indemnified Party's choice and shall in
any event use its reasonable best efforts to cooperate with and assist the
Indemnifying Party. If the Indemnifying Party fails timely to defend, contest or
otherwise protect against such suit, action, investigation, claim or proceeding,
the Indemnified Party shall have the right to do so, including, without
limitation, the right to make any compromise or settlement thereof, and the
Indemnified Party shall be entitled to recover the entire cost thereof from the
Indemnifying Party, including, without limitation, reasonable attorneys' fees,
disbursements and amounts paid as the result of such suit, action,
investigation, claim or proceeding.

         Section 4.4. Indemnification Payments. Any payment hereunder shall be
made by wire transfer of immediately available funds to such account or accounts
as the Indemnified Party shall designate to the Indemnifying Party in writing.

         Section 4.5. Limit on Liability. IN NO EVENT SHALL ANY PARTY BE LIABLE
TO THE OTHER PARTY FOR SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE
LOSS, DAMAGES OR EXPENSES (INCLUDING LOST PROFITS OR SAVINGS).

                                   ARTICLE V

                               DISPUTE RESOLUTION

         Section 5.1. General. Any dispute arising under this Agreement or
otherwise in connection with this Agreement shall be resolved pursuant to this
Section 5.1.

                  (a) Any Party has the right to request the other to meet to
discuss a dispute. The Party requesting the meeting will give at least ten (10)
Business Days notice in writing of the subject it wishes to discuss, provide a
written statement of the dispute, and designate an officer of the Party with
complete power to resolve the dispute to attend the meeting. Within five (5)
Business Days after receipt to such request, the Party receiving the request
will provide a responsive written statement and will designate an officer of the
Party who will attend the meeting with complete power to resolve the dispute.

                  (b) If the meeting fails to resolve the dispute by a signed
agreement among the officers, either Party may submit the dispute for binding
arbitration administered by the American Arbitration Association ("AAA") under
its Commercial Arbitration Rules before a single arbitrator, and judgment on the
award rendered by the arbitrator may be entered in any court having jurisdiction
thereof.

                  (c) The Parties agree to make discovery and disclosure of all
matters relevant to the dispute to the extent and in the manner provided by the
Federal Rules of Civil Procedure. The arbitrator will rule on all requests for
discovery and disclosure and discovery shall be completed within 60 days after
the date of appointment of the arbitrator. The arbitrator may consider any
matter relevant to the subject to the dispute and shall follow the statutes and
decisions of the substantive law of Alaska relevant to the subject. The
arbitrator shall not have the authority or power to alter, amend or modify any
of the terms and conditions of the agreement of the Parties. The arbitrator
shall issue a final ruling within 150 days after the date of appointment of the
arbitrators.

                  (d) The ruling of the arbitrator shall be in writing and
signed and shall be final and binding upon the Parties. The fees and expenses of
counsel, witnesses and employees of the Parties and all other costs and expenses
incurred exclusively for the benefit of the Party incurring the same shall be
borne by the Party incurring such fees and expenses. All other fees and expenses
including, without limitation, compensation for the arbitrator, shall be divided
equally between the Parties. All meetings and arbitrations held pursuant to this
Section 5.1 shall take place in Anchorage, Alaska.

                                            _____________________]


         Any Party may, by notice given in accordance with this Section 6.1 to
the other Parties, designate another address or person for receipt of notices
hereunder provided that notice of such a change shall be effective upon receipt.

         Section 6.2. Successors and Assigns. This Agreement will be binding
upon and inure to the benefit of the Parties and their respective successors,
assigns and legal representatives (whether by acquisition, merger, operation of
law, other transaction constituting a change of control or otherwise).

         Section 6.3. Signatures, Counterparts. Facsimile transmission of any
signed original document and/or retransmission of any signed facsimile
transmission shall be the same as delivery of an original. On request, a Party
will confirm its facsimile transmission by signing a duplicate original
document. This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original and all of which together shall be considered
one and the same agreement.

supplemented only by a written instrument executed by the Parties.

supersede all prior and contemporaneous agreements, understandings, negotiations
and discussions, whether oral or written, of the Parties, and there are no
general or specific warranties, representations or other agreements by or among
the Parties in connection with the entering into of this Agreement or the
subject matter hereof except as specifically set forth or contemplated herein or

         Section 6.7. Negotiated Agreement. This Agreement has been negotiated
by the Parties and the fact that the initial and final draft will have been
prepared by either Party will not give rise to any presumption for or against
any party to this Agreement or be used in any respect or forum in the
construction or interpretation of this Agreement or any of its provisions.

         Section 6.8. Waiver. No consent or waiver, express or implied, by any
Party to or of any breach or default by any other Party in the performance by
such other Party of its obligations hereunder shall be deemed or construed to be
a consent or waiver to or of any other breach or default in the performance of
obligations hereunder by such other Party hereunder. Failure on the part of any
Party to complain of any act or failure to act of any other Party or to declare
any other Party in default, irrespective of how long such failure continues,
shall not constitute a waiver by such first Party of any of its rights
hereunder.

         Section 6.9. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable, each Party directs that such court interpret and
apply the remainder of this Agreement in the manner that it determines most
closely effectuates the Parties' intent in entering into this Agreement, and in
doing so particularly take into account the relative importance of the term,
provision, covenant or restriction being held invalid, void or unenforceable.

         Section 6.10. No Third Party Beneficiaries. Except as set forth in
Article IV, nothing in this Agreement is intended or shall be construed to give
any person, other than the Parties hereto, their successors and permitted
assigns, any legal or equitable right, remedy or claim under or in respect of
this Agreement or any provision contained herein.
