     Subject to the terms and conditions of this Precedent Agreement, any terms
and conditions which may be imposed by the FERC and the terms and conditions of
Southern's Tariff, Southern agrees to provide to Shipper FT Service as described
below. Such FT Service shall be provided in accordance with the terms of a
Service Agreement to be executed between Southern and Shipper. A proforma copy
of the Service Agreement is set forth in Exhibit "B" attached hereto and made a
part hereof. Such Service Agreement shall contain the terms and conditions that
are substantially in accordance with the following:

     (a)  The FT Service will be for the Transportation Demand ("TD") stated in
          MMBtu as set forth on Exhibit "A" attached hereto, commencing on the
          date that both of (1) the Southern facilities comprising the Cypress
          Project, and (2) the FGT Expansion are capable of providing such
          transportation service on a firm daily basis (the "COMMENCEMENT
          DATE").

     (b)  The firm Receipt Point designated on Exhibit "A" to the Service
          Agreement shall be the Elba Island Receipt Point and the firm Delivery
          Point designated on Exhibit "B" to the Service Agreement shall be the

          receipt and delivery points on Southern's system as set forth in
          Southern's Tariff.

     (c)  The initial term of the FT Service described in Section (a) above
          shall be twenty (20) years from the Commencement Date of FT
<PAGE>
                                                                               4


Progress Energy Precedent Agreement (continued)

          Service set forth above (the "PRIMARY TERM"). Shipper shall have the
          right to extend the Primary Term of the Service Agreement for the FT
          Service described in Section (a) above for one or more periods of
          three (3) years at Southern's then applicable maximum lawful rate (any
          such period being hereinafter referred to as an "EVERGREEN EXTENSION")
          by providing Southern with written notice of the exercise of such
          right at least two (2) years prior to the end of the Primary Term or
          any Evergreen Extension thereto.

     (d)  The rate to be charged Shipper for the FT Service shall be a
          negotiated reservation rate of $[*] per MMBtu for the Primary Term of
          this Precedent Agreement and successor Service Agreement, plus the
          maximum commodity charge for the applicable zone(s) of service as set
          forth in Southern's Tariff. The rate to be charged Shipper for fuel
          under this Precedent Agreement and successor Service Agreement shall
          be Southern's generally applicable and approved fuel charge
          established pursuant to Southern's Tariff.

     (e)  In addition to the rates provided for under Section 1(d) above,
          Shipper will compensate Southern for any other FERC approved,
          generally applicable charges or surcharges applicable to the FT
          Service.

     (f)  Southern shall have the unilateral right to file for generally
          applicable changes in its maximum rates or any other provisions in its
          FERC Gas Tariff and the Service Agreement including, but not

Progress Energy Precedent Agreement (continued)

          limited to, provisions relating to compensation for fuel and lost and
          unaccounted for gas or electric usage applicable to the service
          hereunder. Subject to the provisions in Section 1(d) above, such
          changes shall be effective and applicable, subject to refund as
          determined by the FERC, after the required notice or at the end of any
          suspension period ordered by the FERC, and any such rates, charges,
          surcharges or terms and conditions of service accepted by the FERC
          shall be effective under the Service Agreement. It is understood and
          agreed that the generally applicable fuel retention percentage and the
          surcharges set forth in Section 1(e) above are designed to change from
          time to time consistent with Southern's FERC Gas Tariff and FERC
          Regulations. With respect to the services provided under this
          Precedent Agreement (and any successor Service Agreement), and
          notwithstanding the foregoing, (i) Shipper shall not have the right to
          intervene and protest in any rate filing by Southern with respect to
          changes in Southern's recourse rates during the Primary Term of this
          Precedent Agreement or the Service Agreement, and (ii) Shipper shall
          have the right to intervene and protest (a) any filing involving
          generally applicable charges or surcharges in accordance with Sections
          1(e) above, or (b) any filing involving the terms and conditions of
          service in Southern's Tariff, or (c) any rate filing applicable to
          services

Progress Energy Precedent Agreement (continued)

          received by Shipper from Southern other than those provided hereunder.

     (g)  Notwithstanding the rate cap set forth in Section 1(d) above, if,
          while the negotiated reservation rate of $[*] per MMBtu is in effect,
          Southern's costs to provide transportation services are adversely
          affected as a result of State, local or federal legislation or
          regulation specifically including, but not limited to orders,
          regulations, rules or opinions by the FERC, Environmental Protection
          Agency, Department of Transportation, U.S. Army Corps of Engineers,
          Internal Revenue Service, U. S. Fish and Wildlife Service or any other
          State or federal agency or court of law and/or any changes in
          Generally Accepted Accounting Principles (GAAP), that has a general or
          industry wide effect which causes the total cost of service to
          Southern of providing Shipper the transportation service to be
          materially and adversely increased; then Southern may provide written
          notice to Shipper requesting to increase Shipper's rates to take into
          account the costs associated with the legislation or regulation. For
          purposes of the previous sentence, "materially and adversely" shall be
          defined as an overall increase in Southern's total cost of service to
          provide service to Shipper as contemplated by this Precedent Agreement
          of 25% or more (after taking into consideration any offsetting
          decreases in other costs or increases in other revenues from
          regulatory events such as those described

                                                                               7


Progress Energy Precedent Agreement (continued)

          above), calculated on a net present value basis, discounted at an 8%
          discount rate. Such written notice requesting an adjustment in the
          rates shall specifically state (i) the legislation or regulation
          impacting such costs or revenues; (ii) the obligation by Southern to
          comply with such regulation or legislation; and (iii) how, and the
          extent to which, such legislation or regulation materially and
          adversely increases Southern's total cost of service to provide
          service to Shipper as contemplated by this Precedent Agreement. Once
          Southern has provided such notice, the Parties shall meet within
          thirty (30) days to discuss possible means of correcting the material
          and adverse impact and shall attempt in good faith to negotiate a
          mutually acceptable solution, including, but not limited to, an
          amendment to the rate discount through an increase of the reservation
          or transportation charges. If the Parties are unable within 120 days
          after the receipt of such notice to agree upon a mutually acceptable
          solution, then either Party may, upon 30 days prior written notice to
          the other, invoke alternative dispute resolution procedures consistent
          with the commercial arbitration rules of the American Arbitration
          Association in order to determine how to mitigate the adverse impact
          in light of all of the facts and circumstances existing at that time.
          Any rate increase agreed upon by Southern and Shipper or that is
          approved through the alternate dispute resolution procedures shall
          only go into effect prospectively
<PAGE>
                                                                               8


Progress Energy Precedent Agreement (continued)

          commencing upon the date that either the Parties agree upon the rate
          change or such rate change is approved through the alternate dispute
          resolution procedures. Notwithstanding the foregoing, no rate increase
          or increases adopted pursuant to this Section 1(g), whether agreed to
          by Southern and Shipper or approved through the alternate dispute
          resolution procedures described herein, shall result in an aggregate
          increase in the negotiated reservation rate provided hereunder of more
          than twenty-five percent (25%).

2.   APPROVALS; COOPERATION.

     (a)  Upon execution of this Precedent Agreement, Southern and Shipper agree
          to promptly seek, and to exercise good faith efforts to cause any and
          all other parties whose participation is required to promptly seek the
          regulatory approvals, including from the FERC all necessary
          authorizations under the Natural Gas Act (the "FERC AUTHORIZATIONS"),
          as may be necessary to construct, install and operate the Cypress
          Project consistent with the terms of this Precedent Agreement.
          Southern and Shipper reserve the right to file and prosecute
          applications for any required authorizations, any supplement or
          amendment to an application, and any court review as each deems in its
          best interests.

     (b)  Southern shall provide Shipper from time to time, but in no event less
          frequently than once a month, with updates of its progress in
          obtaining the FERC Authorizations to construct the Cypress Project.
<PAGE>
                                                                               9


Progress Energy Precedent Agreement (continued)

     (c)  Southern and Shipper each agree to execute and deliver all other
          additional instruments and documents, and to do all other acts, as may
          be reasonably necessary to effectuate the terms and provisions of this
          Precedent Agreement.

     (d)  Southern shall not be obligated to prosecute its application with the
          FERC or seek any other regulatory approvals or permit applications or
          proceed with the construction of the Cypress Project unless and until
          it holds an open season soliciting bids from other shippers.

     (e)  Once the open season for subscription for the Cypress Project has
          closed and been finalized, Southern will actively pursue design,
          engineering and title work as necessary to facilitate the filing of
          the FERC Authorizations and the FERC review process, but it shall not
          be required to commit significant capital expenditures for
          right-of-way or materials for the project unless and until it receives
          a Preliminary Determination, as defined in Section 5(a)(i)(B) below,
          from the FERC approving the commercial aspects of the filing in a
          manner acceptable to Southern or until all conditions precedent set
          forth in Section 5(b) below are met by Shipper.

3.   ACCEPTANCE OF FERC AUTHORIZATION.

          Within 10 business days of Southern receiving the FERC Authorizations,
     Southern shall notify Shipper of its intent to accept or reject the FERC
     Authorizations. Shipper shall, within fifteen (15) days after the date
     Southern provides an electronic copy to Shipper by e-mail of FERC's
<PAGE>
                                                                              10


Progress Energy Precedent Agreement (continued)

          Preliminary Determination on the Cypress Project, notify Southern in
          writing of any terms or conditions in the Preliminary Determination
          that materially and adversely affect Shipper, as further defined
          below, and whether Shipper has any material objections to such
          Preliminary Determination. Neither Southern, in the case of the FERC
          Authorizations, nor Shipper, in the case of the Preliminary
          Determination, shall be under any obligation to accept the respective
          terms of the FERC Authorizations or Preliminary Determination if they
          contain terms or conditions which are reasonably likely to have a
          material and adverse effect. A material and adverse effect shall be
          defined as (i) having a material and adverse impact on the financial
          benefits to either Southern or Shipper arising out of the transactions
          contemplated hereby, or (ii) imposing upon Southern or Shipper
          material business or regulatory risks, as Southern or Shipper,
          respectively, in their sole discretion shall determine or (iii) being
          directly contrary to the terms and conditions contained in this
          Precedent Agreement. Such material business or regulatory risks could
          include, but not be limited to, the ability of Southern to obtain
          rolled-in rate treatment for the Cypress Project.

               Notwithstanding the above, in the event the FERC Authorizations
          or Preliminary Determination contain unsatisfactory, material terms
          and conditions consistent with the provision described above, Shipper
          and Southern agree that, prior to the date by which rehearing must be
          requested of the Preliminary Determination in the case where Shipper
          objects to the
<PAGE>
                                                                              11


Progress Energy Precedent Agreement (continued)

          Preliminary Determination or the date that Southern must accept the
          certificate under Section 157.20 of the FERC Regulations in the case
          where Southern objects to the FERC Authorizations, Southern and
          Shipper will discuss potential options to adjust the rate set forth
          above in Paragraph 1(d) in order to compensate, as appropriate, (i)
          Southern for accepting the certificate and proceeding with the Cypress
          Project and the transaction contemplated herein, and (ii) Shipper for
          accepting the Preliminary Determination and proceeding with the
          transaction contemplated herein. If the Parties can agree on the means
          to adjust the rate, then they will document such agreement by
          execution of an amendment to this agreement or execution of a Service
          Agreement with the applicable terms prior to the date by which
          rehearing requests are due for the Preliminary Determination or
          Southern is required to accept the FERC certificate. In the event that
          Shipper issues notice in writing to Southern of its objection to the
          terms of the Preliminary Determination or Southern issues notice in
          writing to Shipper of its objection to the terms of the FERC
          Authorizations, and the Parties cannot agree on the means to adjust
          the rate, then the Party issuing the notice of objections shall have
          the right to terminate this Precedent Agreement. Such right must be
          exercised by written notice to the other Party provided, respectively,
          by Shipper no later than the date upon which rehearing requests for
          the Preliminary Determination are due or by Southern no later than
          twenty-nine (29) days after issuance of the certificate and such right
          to terminate under this Section 3 shall be deemed to be

                                                                              12


Progress Energy Precedent Agreement (continued)

          waived if such right is not exercised by providing such notice in the
          manner and within the times specified herein. In the event either
          Party provides the other Party with notice of its objection to the
          Preliminary Determination or the terms of the FERC Authorizations as
          set forth above but does not exercise its right to terminate this
          Precedent Agreement under this Section 3, the Parties shall remain
          bound to perform their obligations under this Precedent Agreement.

               Nothing contained herein shall prevent Southern or Shipper from
          seeking rehearing of any unfavorable term or condition contained in
          the Preliminary Determination or the FERC Authorizations in a manner
          that is consistent with the terms of this Precedent Agreement or the
          Service Agreement, even if Southern accepts the certificate as
          provided above.

4.   SERVICE AGREEMENT; IN-SERVICE DATE.

     (a)  Subject to the satisfaction or waiver of the conditions precedent set
          forth in Section 5 below, within ten (10) days of Southern filing with
          the FERC a letter of acceptance, Southern and Shipper shall execute
          and deliver a standard form of firm Service Agreement as set forth in
          Exhibit "B", attached hereto and made a part hereof, that incorporates
          terms and conditions that are substantially in accordance with Section
          1 above.

     (b)  Upon execution and delivery of the Service Agreement by each Party and
          once all of the Conditions Precedent set forth in Section 5 below are

          by May 1, 2007, or such other mutually agreeable date (the "IN SERVICE
          DATE"). Shipper agrees and understands that any delays in receiving
          FERC approval may cause delays in reaching the In Service Date.
          Southern and Shipper will discuss any changes to the In Service Date
          based on the status of the regulatory process. At Shippers request,
          Southern agrees to timely review with Shipper its design drawings and
          specifications, bill of material, bid results, and construction
          contract and specifications (collectively, the "CONSTRUCTION
          DOCUMENTS") for the construction of the Cypress Project to Shipper so
          that Shipper is kept abreast of Southern's construction progress.

               (vi) demonstration to Southern's satisfaction on or before

                    its financial obligations required under the terms of this
                    Precedent Agreement that would support the construction of
                    the Cypress Pipeline by demonstrating Shipper's ability to
                    sustain the transaction under its own capital structure, or
                    produce Southern with credit assurances of either (i) an
                    acceptable intracorporate guarantee or (ii) letter of credit
                    or other comparable surety with the value of at least two
                    and one-half (2 1/2) years of transportation demand payments
                    at Shipper's MDQ set forth above in Section 1(a).
                    Notwithstanding the date set forth above in which the
                    condition precedent must be satisfied, Shipper shall be
                    obligated to sustain its showing of creditworthiness
                    throughout the term of the Service Agreement by providing
                    Southern with one of the acceptable credit assurances listed
                    above. This condition precedent may not be waived by

          Shipper or Southern may terminate this Agreement by giving written
          notice to the other Party thereof at any time after the date the
          applicable condition precedent was to be satisfied or waived, but
          prior to the satisfaction or waiver of the applicable condition
          precedent. Upon such termination, neither Southern nor Shipper shall
          have any further obligations under this Precedent Agreement. Such
          notice shall be effective as of the date it is delivered to the U. S.
          Mail for delivery by certified mail, return receipt requested.

     (c)  The Government Authorizations required by Sections 5(a)(i) and
          5(b)(iii) and (v) shall be final and duly granted without contingency
          by the authorities having jurisdiction; provided, however, that
          Southern or Shipper may, at their option, elect to waive the condition
          that such approvals be final.

7.   ASSIGNMENT AND DELEGATION.

     (a)  Any entity that succeeds by purchase, merger, or consolidation to the
          properties substantially as an entirety of either Southern or Shipper,
          as the case may be, shall be entitled to the rights and subject to the
          obligations set out in this Precedent Agreement and the executed
          Service Agreement.

     (b)  Either Party may, without the consent of the other Party, assign any
          of its rights hereunder to an Affiliate of assignor, but the assignor
          shall not be relieved of its obligations under this Precedent
          Agreement until the nonassigning Party receives an agreement from the
          assignee that it is assuming all the terms and conditions hereto and
          such assignee is financially and technically capable of meeting such
          terms and
<PAGE>
                                                                              20


Progress Energy Precedent Agreement (continued)

          conditions. The assignor shall provide written notice of the
          assignment to the other Party to this Precedent Agreement as soon as
          practicable after such assignment. For the purpose of this Section
          7(b), the term "Affiliate" shall mean an individual or entity that
          directly, or indirectly through one or more intermediaries, controls,
          is controlled by or is under common control with another individual or
          entity. The terms "controls," "controlled," and "control" in the
          preceding sentence shall mean the possession, direct or indirect, of
          the power to direct the management and policies of an entity, whether
          through the ownership of voting securities or otherwise.

     (c)  Except as provided above in Sections 7(a) or 7(b) of this Precedent
          Agreement, no assignment of rights or delegation of duties under this
          Precedent Agreement shall be made unless there first shall have been
          obtained the written consent of Shipper, in the event of an assignment
          or delegation by Southern, or the written consent of Southern, in the
          event of an assignment or delegation by Shipper, such consents not to
          be unreasonably withheld. Southern and Shipper agree, however, that
          the restrictions on assignment contained in this Paragraph shall not
          in any way prevent either Southern or Shipper from pledging or
          mortgaging its rights hereunder as security for its indebtedness.

8.   TERM.

     Subject to the provisions of Section 5 hereof, this Precedent Agreement
shall remain in full force and effect until it is superceded by the execution by
the

                                                                              21


Progress Energy Precedent Agreement (continued)

Parties of an effective Service Agreement as provided in Section 4 above or
otherwise terminated in accordance with the provisions of this Precedent
Agreement, except for the provisions of Sections 1 and 9 hereof which shall
survive the execution of an effective Service Agreement and remain binding and
effective on the Parties in accordance with their respective terms.

9.   NEGOTIATED RATE FOR FUTURE CYPRESS PROJECT EXPANSIONS

     In the event that BG LNG Services LLC does not satisfy or waive the
conditions precedent in its Precedent Agreement with Southern for the Cypress
Project to subscribe to Phase II and/or Phase III of the Cypress Project by the
dates set forth in such Precedent Agreement, as such Phases are defined in the
FERC Authorizations for the Cypress Project referenced above in Section 2(a),
Shipper shall have the right to subscribe to up to [*] MMbtu of such expansion
capacity per phase provided that Southern can achieve adequate subscription from
other shippers to make the project economical to Southern. In conjunction with
such right, Southern and Shipper agree that the reservation rate to be charged
Shipper for each phase, respectively, shall be the lower of: (a) the recourse
rate filed by Southern for the applicable expansion facilities; or (b) the
lowest rate charged by Southern or paid by other shippers for the respective
Cypress expansion capacity; or (c) for Phase II only, $[*], if Shipper
subscribes for the expansion capacity within ninety (90) days after being
notified by Southern that the expansion capacity is available; provided,
however, that such notice shall not be sent to Shipper any earlier than January
2, 2008.

     (e)  If a court of competent jurisdiction declares any provision of this
          Precedent Agreement unenforceable, then that provision shall be
          severed from this Precedent Agreement, which shall otherwise remain in
          full force and effect and be construed as if it did not contain the
          severed provision.

     (f)  Except as expressed otherwise in this Precedent Agreement, nothing
          expressed or implicit in this Precedent Agreement shall confer on

     (h)  The Parties expressly agree that the laws of the State of Alabama,
          without regard for any rules for conflicts of law, shall govern the
          validity, effect, construction, and interpretation of this Precedent
          Agreement.

     (i)  This Precedent Agreement constitutes the entire agreement between the
          Parties and no waiver by either Party or any default of either Party
          under this agreement shall operate as a waiver of any subsequent
          default whether it is of a like or different character.

1.3 Technical Meanings.  Words not otherwise defined herein that have well-known
and generally accepted technical or trade meanings are used herein in accordance
with such recognized meanings, as of the Effective Date.

SECTION 2. TERM; DELIVERY PERIOD

2.1 The term of this Contract (the "Term") shall commence on the Effective Date
and shall remain in effect until the expiration of the Delivery Period, unless
otherwise extended by written agreement of the Parties.

2.2 In the event that, prior to the first date of the Delivery Period as defined
above, Seller and Buyer mutually agree to move up the first day of the Delivery
Period, the Parties shall execute a written amendment to this Contract
re-defining "Delivery Period" to reflect the new start date thereof.

SECTION 3. PERFORMANCE OBLIGATIONS

3.1 Seller agrees to sell and deliver to Buyer, and Buyer agrees to receive and
purchase from Seller, the Contract Quantity on a Firm basis at the Delivery
Point(s) each Day during the Delivery Period in accordance with the terms and
conditions of this Contract.

3.2 With respect to each Month during the Delivery Period, Buyer shall pay to
Seller an amount equal to the product of: (i) the amount of Gas actually
delivered by Seller to Buyer in such Month, and (ii) the Contract Price
applicable to such Month (as determined pursuant to Section 3.3).

3.3 Unless otherwise agreed between the Parties pursuant to this Section 3.3,
the Contract Price with respect to each delivery Day during a particular Month,
shall be the price (expressed in U.S. Dollars per MMBtu) for such Month as
published in Inside FERC's Gas Market Report (as published by The McGraw-Hill
Companies, Inc. or its successor), under the heading "Market Center Spot-Gas
Prices" "South Louisiana" "Henry Hub" "Midpoint", [*] per MMBtu. For any
particular Month during the Term, the Parties may agree to change the Contract
Price for such Month from that which is described in the previous sentence to
either a fixed dollar amount per MMBtu, or a price based on another index (other
than the Inside FERC index referenced above), in either case as mutually agreed
by the Parties pursuant to the procedures set forth in Section 3.5.

3.4 Unless otherwise agreed between the Parties pursuant to this Section 3.4,
the Delivery Point with respect to each delivery Day during a particular Month,
shall be the Primary Delivery Point. For any particular Month during the Term,
the Parties may agree to change the Delivery Point for such Month to an
Alternate Delivery Point pursuant to the procedures set forth in Section 3.5.

3.5 To effect a change to the Contract Price for one or more Months (a "Price
Change"), or to effect a change from the Primary Delivery Point to an Alternate
Delivery Point for one or more Months (a "Delivery Point Change"), the Party
seeking such change must make such request of the other Party prior to 2:30 P.M.
Eastern Prevailing Time on the last trading day of the NYMEX gas futures
contract (Henry Hub) of the Month immediately preceding the relevant Month or
Months for which the change would be effective. Each Party shall exercise
reasonable efforts to accept such a proposed change; provided, however, that a
Party shall not be required to accept a change that would not be commercially
reasonable for such a Party. The Parties acknowledge that Seller's source of Gas
for use under this Contract is regasified LNG delivered to the Elba Island LNG
Terminal, and therefore any proposed change in Delivery Point that does not
allow delivery from the Elba Island LNG Terminal is not commercially reasonable
for Seller. If

<PAGE>
the Party to whom the request is made accepts the proposed change, such
agreement between the Parties may be effectuated through a recorded telephone
conversation, with the offer and acceptance constituting the agreement of the
Parties. The Parties shall be legally bound from the time they so agree to the
terms of such Price Change or Delivery Point Change and may each rely thereon.
Any such agreement shall be considered to be a "writing" and to have been
"signed" for all purposes hereunder. Notwithstanding the foregoing sentence, the
Parties agree that either Party may confirm a telephonic transaction by sending
the other Party a Confirmation via facsimile or other mutually agreeable means
within a reasonable time of such agreement; provided that the failure of either
or both Parties to send a Confirmation shall not invalidate the oral agreement
of the Parties. The confirming Party adopts its confirming letterhead, or the
like, as its signature on any Confirmation as the identification and
authentication of the confirming Party. If the Confirmation contains any
provision other than those relating to the terms of the Price Change or Delivery
Point Change (i.e. any terms other than the applicable Month and the
newly-agreed Contract Price or Delivery Point for such Month), which modify or
supplement this Contract, such provisions shall not be binding on the receiving
Party; provided that the foregoing shall not invalidate any Price Change or
Delivery Point Change agreed to by the Parties. Any failure by either or both
Parties to send a Confirmation for any Price Change or Delivery Point Change
shall not affect the enforceability of any such Price Change or Delivery Point
Change actually entered into nor shall such failure constitute or be deemed to
constitute a breach of this Contract. If a sending Party's Confirmation is
materially different from the receiving Party's understanding of the agreement
concerning the applicable Price Change or Delivery Point Change, such receiving
Party shall notify the sending Party in writing (facsimile acceptable) within
two Business Days of receipt of such Confirmation and the Parties shall work
together to resolve the discrepancies. The failure of the receiving Party to so
notify the sending Party in writing by such deadline constitutes the receiving
Party's agreement to the terms of the applicable Price Change or Delivery Point
Change described in the sending Party's Confirmation. If there are any material
differences between timely sent Confirmations governing the same Price Change or
Delivery Point Change, then neither Confirmation shall be binding with respect
to the differing terms until or unless such differences are resolved including
the use of any evidence that clearly resolves the differences in the
Confirmations. In the event of a conflict among the terms of (i) a binding
Confirmation (including by deemed acceptance as described above), (ii) the oral
agreement of the Parties which may be evidenced by a recorded conversation, and
(iii) this Contract, the terms of the documents shall govern in the priory
listed in this sentence.

3.6 The Parties may agree to a Price Change that results in a fixed price
("Fixed Price") as opposed to a Contract Price that floats based on NYMEX,
industry postings, reference publications, or other external market factors or
indices. If a Fixed Price is established and, for any reason whatsoever (other
than a breach or default by either Party under this Contract), including,
without limitation, an event of Force Majeure or any circumstance (other than a
breach or default by either Party under this Contract) that would excuse a
Party's obligation to deliver or receive Gas under this Contract, Seller
delivers or Buyer takes less than the full Contract Quantity for such Month (a
"Monthly Deficiency"), then (1) Buyer shall pay Seller an amount equal to such
Monthly Deficiency (expressed in MMBtus) multiplied by the amount, if any, by
which the Fixed Price exceeds the applicable NYMEX Natural Gas futures contract
price for such Month, or (2) Seller shall pay to the Buyer an amount equal to
such Monthly Deficiency (expressed in MMBtus) multiplied by the amount, if any,
by which the applicable NYMEX Natural Gas futures contract for such Month
exceeds the Fixed Price established for such Month.

SECTION 4. TRANSPORTATION, NOMINATIONS AND IMBALANCES

4.1 Seller shall have the sole responsibility for transporting the Gas to the
Delivery Point(s). Buyer shall have the sole responsibility for transporting the
Gas from the Delivery Point(s).

4.2 The Parties shall coordinate their nomination activities, giving sufficient
time to meet the deadlines of the affected Transporter(s). Each Party shall give
the other Party timely prior notice, sufficient to meet the requirements of all
Transporter(s) involved in the transaction, of the quantities of Gas to be
delivered and purchased each Day. Should either Party become aware that actual
deliveries at the Delivery Point(s) are greater or lesser than the Scheduled
Gas, such Party shall promptly notify the other Party.

4.3 The Parties shall use commercially reasonable efforts to avoid imposition of
any Imbalance Charges. If Buyer or Seller receives an invoice from a Transporter
that includes Imbalance Charges, the Parties shall determine the validity as
well as the cause of such Imbalance Charges. If the Imbalance Charges were
incurred as a result of Buyer's receipt of quantities of Gas greater than or
less than the Scheduled Gas, then Buyer shall pay for such Imbalance Charges or
reimburse Seller for such Imbalance Charges paid by Seller. If the Imbalance
Charges were incurred as a result of Seller's delivery of quantities of Gas
greater than or less than the Scheduled Gas, then Seller shall pay for such
Imbalance Charges or reimburse Buyer for such Imbalance Charges paid by Buyer.
Notwithstanding anything to the contrary herein, in the event of Force Majeure,
the Parties shall follow the procedures set forth in Section 12.8 and each Party
shall be responsible for any Imbalance Charges arising out of its
non-conformance with such procedures.

SECTION 5. QUALITY AND MEASUREMENT

All Gas delivered by Seller shall meet the requirements of the Receiving
Transporter's pipeline specifications for pipeline quality Gas. The unit of
quantity measurement for purposes of this Contract shall be one MMBtu dry.
Measurement of Gas quantities hereunder shall be in accordance with the
established procedures of the Receiving Transporter.

SECTION 6. TAXES

Seller shall pay or cause to be paid all taxes, fees, levies, penalties,
licenses or charges imposed by any Government Agency ("Taxes") on or with
respect to the Gas prior to the Delivery Point(s). Buyer shall pay or cause to
be paid all Taxes on or with respect to the Gas at the Delivery Point(s) and all
Taxes after the Delivery Point(s). If a Party is required to remit or pay Taxes
that are the other Party's responsibility hereunder, the Party responsible for
such Taxes shall promptly reimburse the other Party for such Taxes. Any Party
entitled to an exemption from any such Taxes or charges shall furnish the other
Party any necessary documentation thereof. Failure by either Party to furnish
such documentation shall not give rise to a breach of this Contract.

SECTION 7. BILLING, PAYMENT AND AUDIT

7.1 Seller shall invoice Buyer for Gas delivered and received in the preceding
Month and for any other applicable charges, providing supporting documentation
acceptable in industry practice to support the amount charged. If the actual
quantity delivered is not known by the billing date, billing will be prepared
based on the quantity of Scheduled Gas. The invoiced quantity will then be
adjusted to the actual quantity on the following Month's billing or as soon
thereafter as actual delivery information is available.

7.2 Buyer shall remit the amount due under Section 7.1 via wire transfer or ACH,
in immediately available funds, on or before the Payment Date. Except as
otherwise provided in Section 7.3, in the event any payments are due Buyer
hereunder, payment to Buyer shall be made in accordance with this Section 7.2.

7.3 In the event payments become due pursuant to Section 13, the performing
Party may submit an invoice to the non-performing Party for an accelerated
payment setting forth the basis upon which the invoiced amount was calculated.
Payment from the non-performing Party shall be due within five (5) Business Days
after receipt of invoice.

7.4 If the invoiced Party, in good faith, disputes the amount of any such
invoice or any part thereof, such invoiced Party will pay the portion of such
amount as it concedes to be correct; provided, however, if the invoiced Party
disputes the amount due, it must provide supporting documentation acceptable in
industry practice to support the amount paid or disputed. In the event the
Parties are unable to resolve such dispute, either Party may pursue any remedy
available at law or in equity to enforce its rights pursuant to this Section 7.

7.5 If the invoiced Party fails to remit the full amount payable when due,
interest on the unpaid portion shall accrue from the date due until the date of
payment at a rate equal to the lower of (i) the then-effective prime rate of
interest published under "Money Rates" by The Wall Street Journal, plus two
percent per annum; or (ii) the maximum applicable lawful interest rate.

7.6 A Party shall have the right, at its own expense, upon reasonable Notice and
at reasonable times, to examine and audit and to obtain copies of the relevant
portion of the books, records and telephone recordings of the other Party only
to the extent reasonably necessary to verify the accuracy of any statement,
charge, payment or computation made under this Contract. This right to examine,
audit and obtain copies shall not be available with respect to proprietary
information not directly relevant to obligations under this Contract. Such right
shall include, but not be limited to, copies of any and all statements and/or
records pertaining to transportation of Gas with respect to which any such
transportation charges are included in billing and/or invoices hereunder, and/or
are the subject of any bona fide dispute between the Parties, and without regard
as to whether such records and/or statements were generated by the Party being
audited or the relevant Transporter. All invoices and billings shall be
conclusively presumed final and accurate and all associated claims for
underpayments or overpayments shall be deemed waived unless such invoices or
billings are objected to in writing, with adequate explanation and/or
documentation, within two years after the Month of Gas delivery. All retroactive
adjustments under Section 7 shall be paid in full by the Party owing payment
within 30 Days of Notice and substantiation of such inaccuracy.

7.7 The Parties shall net all undisputed amounts due and owing, and/or past due,
arising under this Contract such that the Party owing the greater amount shall
make a single payment of the net amount to the other Party in accordance with
Section 7.2; provided that no payment required to be made pursuant to the terms
of Section 10 shall be subject to netting under this Section 7.7.

SECTION 8. TITLE, WARRANTY AND INDEMNITY

8.1 Unless otherwise specifically agreed, title to the Gas shall pass from
Seller to Buyer at the Delivery Point(s). Seller shall have responsibility for
and assume any liability with respect to the Gas prior to its delivery to Buyer
at the specified Delivery Point(s). Buyer shall have responsibility for and
assume any liability with respect to said Gas after its delivery to Buyer at the
Delivery Point(s).

8.2 Seller warrants that it will have the right to convey and will transfer good
and merchantable title to all Gas sold hereunder and delivered by it to Buyer,
free and clear of all liens, encumbrances and claims. EXCEPT AS OTHERWISE
PROVIDED HEREIN, ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY
WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR ANY PARTICULAR PURPOSE, ARE
DISCLAIMED.

8.3 Seller agrees to indemnify and defend Buyer and its Affiliates, and their
respective agents, employees, officers and directors, and save them harmless
from all losses, liabilities or claims including reasonable attorneys' fees and
costs of court ("Claims"), from any and all Persons, arising from or out of
claims of title, personal injury or property damage from said Gas or other
charges thereon which attach before title passes to Buyer, except to the extent
attributable to Buyer's negligence or willful misconduct. Buyer agrees to
indemnify and defend Seller and its Affiliates, and their respective agents,
employees, officers and directors, and save them harmless from all Claims, from
any and all persons, arising from or out of claims regarding payment, personal
injury or property damage from said Gas or other charges thereon which attach
after title passes to Buyer, except to the extent attributable to Seller's
negligence or willful misconduct. Each Party shall indemnify, defend and hold
harmless the other Party against any taxes for which such Party is responsible
under Section 6.

8.4 Notwithstanding the other provisions of this Section 8, as between Seller
and Buyer, Seller will be liable for all Claims to the extent that such arise
from the failure of Gas delivered by Seller to meet the quality requirements of
Section 5.

10.2 The Parties agree that the provisions of the Credit Support Annex set forth
the exclusive conditions under which a Party shall be required to transfer
Performance Assurance to the other Party as well as the exclusive conditions
under which a Party shall release such Performance Assurance, and the Parties
agree to abide by all of the terms and conditions of the Credit Support Annex.

SECTION 11. EVENTS OF DEFAULT; REMEDIES

11.1 An "Event of Default" shall mean, with respect to a Party (the "Defaulting
Party"), the occurrence of any of the following: Such Party shall (i) make an
assignment or any general arrangement for the benefit of creditors; (ii) file a
petition or otherwise commence, authorize, or acquiesce in the commencement of a
proceeding or case under any bankruptcy or similar law for the protection of
creditors or have such petition filed or proceeding commenced against it; (iii)
otherwise become bankrupt or insolvent (however evidenced); (iv) be unable to
pay its debts as they fall due; (v) have a receiver, provisional liquidator,
conservator, custodian, trustee or other similar official appointed with respect
to it or substantially all of its assets; (vi) fail to provide Performance
Assurance to the other Party pursuant to the terms of the Credit Support Annex;
(vii) not have paid any amount due the other Party hereunder on or before the
second Business Day following written Notice that such payment is due and such
amount is not the subject of a bona fide dispute pursuant to Section 7.4; (viii)
make any representation or warranty herein that was false or misleading in any
material respect when made or when deemed made or repeated; (ix) fail to perform
any material covenant or obligation set forth in this Contract (except to the
extent constituting a separate Event of Default, and except for such Party's
obligations to deliver or receive Gas, the exclusive remedy for which is
provided in Section 13) if such failure is not remedied within three (3)
Business Days after written notice; (x) be the subject of a Merger Event; (xi)
disaffirm, disclaim, repudiate or reject, in whole or in part, or challenge the
validity of, this Contract; (xii) fail to deliver or take delivery of the
Contract Quantity for a cumulative sixty (60) Days in any twelve (12) month
period or any thirty (30) Days in succession, in either case if such failure is
not excused, (xiii) failure of Seller to cause its Guarantor to provide to Buyer
a Guarantee as provided in Section 10.1 if such failure is not remedied by
Seller within five (5) Business Days of Buyer sending a Notice of such failure
to Seller; or (xiv) with respect to Seller's Guarantor only, the failure of
Seller's Guarantor's Guarantee to be in full force and effect for purposes of
this Contract (other than in accordance with its terms) prior to the
satisfaction of all obligations of Seller hereunder without the written consent
of Buyer, or such Guarantor shall repudiate, disaffirm, disclaim, or reject, in
whole or in part, or challenge the validity of the Guarantee.

11.2 If an Event of Default has occurred and is continuing, the Party that is
not the Defaulting Party (the "Non-Defaulting Party"), shall have the right in
its sole discretion to (i) designate a day (the "Early Termination Date") by
providing the Defaulting Party with written notice thereof, which such day shall
be within 20 days after the delivery of such Notice, upon which the
Non-Defaulting Party will accelerate all amounts owing between the Parties
hereunder and liquidate and terminate this Contract pursuant to Section 11.3;
(ii) withhold payments due to the Defaulting Party under this Contract; and/or
(iii) suspend performance under this Contract.

11.3 If the Non-Defaulting Party elects to liquidate and terminate this
Contract, the Non-Defaulting Party shall determine, as of the Early Termination
Date, in good faith and in a commercially reasonable manner, (i) the amount owed
(whether or not then due) by each Party with respect to all Gas delivered and
received between the Parties under this Contract on and before the Early
Termination Date and all other applicable charges relating to such deliveries
and receipts (including without limitation any amounts owed under Section 13),
for which payment has not yet been made by the Party that owes such payment
under this Contract and (ii) the Market Value, as defined below, of this
Contract. The Non-Defaulting Party shall liquidate and accelerate this Contract
at its Market Value, so that the amount equal to the difference between such
Market Value and the Contract Value, as defined below, shall be due to Buyer if
such Market Value exceeds the Contract Value and to Seller if the opposite is
the case. "Contract Value" means the amount of Gas remaining to be delivered or
purchased under this Contract multiplied by the applicable Contract Price(s),
and "Market Value" means the amount of Gas remaining to be delivered or
purchased under this Contract multiplied by the market price for a similar
transaction at the Delivery Point (or in the event Buyer is the Non-Defaulting
Party and is unable to obtain a reasonable determination of


                                       11

Gas Sale and Purchase Contract (December 1, 2004)
<PAGE>
the market price at the Primary Delivery Point, then at any other delivery point
that is reasonably geographically close to the Primary Delivery Point where
Buyer is able to obtain a reasonable determination of the market price),
determined by the Non-Defaulting Party in a commercially reasonable manner; in
each case, discounting each amount that would have otherwise been due under this
Contract to present value in a commercially reasonable manner as of the Early
Termination Date (to take account of the period between the date of liquidation
and the date on which such amount would have otherwise been due pursuant to this
Contract). To ascertain the Market Value, the Non-Defaulting Party may consider,
among other valuations, any or all of the settlement prices of NYMEX Gas futures
contracts, quotations from leading dealers in energy swap contracts or physical
gas trading markets, similar sales or purchases and any other bona fide
third-party offers, all adjusted for the length of the remaining portion of the
Term and differences in transportation costs (including but not limited to the
availability and cost of firm capacity on pipelines and the cost of pipeline
expansion capacity if firm capacity is not available). A Party shall not be
required to enter into a replacement transaction(s) in order to determine the
Market Value. Any extension(s) of the Term to which the Parties are not bound as
of the Early Termination Date shall not be considered in determining Contract
Value and Market Value. For the avoidance of doubt, any option pursuant to which
one Party has the right to extend the Term shall not be considered in
determining Contract Value and Market Value. The rate of interest used in
calculating net present value shall be determined by the Non-Defaulting Party in
a commercially reasonable manner.

11.4 The Non-Defaulting Party shall net or aggregate the following, as
appropriate: (1) any and all amounts owing between the Parties under Section
11.3, (2) any Costs incurred by the Non-Defaulting Party, and (3) any amounts
received by a Party as a result of exercising its rights to apply or realize
against Performance Assurance in accordance with the Credit Support Annex, so
that all such amounts are netted or aggregated to a single liquidated amount
payable by one Party to the other (the "Net Settlement Amount").

11.5 If any obligation that is to be included in any netting, aggregation or
setoff pursuant to Section 11.4 is unascertained, the Non-Defaulting Party may
in good faith estimate that obligation and net, aggregate or setoff, as
applicable, in respect of the estimate, subject to the Non-Defaulting Party
accounting to the Defaulting Party when the obligation is ascertained. Any
amount not then due which is included in any netting, aggregation or setoff
pursuant to Section 11.4 shall be discounted to net present value in a
commercially reasonable manner determined by the Non-Defaulting Party.

11.6 As soon as practicable after a liquidation, Notice shall be given by the
Non-Defaulting Party to the Defaulting Party of the Net Settlement Amount, and
whether the Net Settlement Amount is due to or due from the Non-Defaulting
Party. The Notice shall include a written statement explaining in reasonable
detail the calculation of such amount, provided that failure to give such Notice
shall not affect the validity or enforceability of the liquidation or give rise
to any claim by the Defaulting Party against the Non-Defaulting Party. The Net
Settlement Amount shall be paid by the Party that owes it by the close of
business on the second Business Day following the receipt of such Notice, which
date shall not be earlier than the Early Termination Date. Interest on any
unpaid portion of the Net Settlement Amount shall accrue from the date due until
the date of payment at a rate equal to the lower of (i) the then-effective prime
rate of interest published under "Money Rates" by The Wall Street Journal, plus
two percent per annum; or (ii) the maximum applicable lawful interest rate.

11.7 After calculation of a Net Settlement Amount in accordance with Section
11.4, if the Defaulting Party would be owed the Net Settlement Amount, the
Non-Defaulting Party shall be entitled, at its option and in its discretion, to
(i) set off against such Net Settlement Amount any amounts due and owing by the
Defaulting Party to the Non-Defaulting Party under any other agreements,
instruments or undertakings between the Defaulting Party and the Non-Defaulting
Party and/or (ii) to the extent any such amounts are not yet liquidated in
accordance with Section 11.3, withhold payment of the Net Settlement Amount to
the Defaulting Party. The remedy provided for in this Section 11.7 shall be
without prejudice and in addition to any right of setoff, combination of
accounts, lien, deduction, retention or withholding or other right to which any
Party is at any time otherwise entitled (whether by operation of law, contract
or otherwise).

Gas Sale and Purchase Contract (December 1, 2004)
<PAGE>
11.8 If the Defaulting Party disputes the Non-Defaulting Party's calculation of
the Net Settlement Amount, the Defaulting Party shall, within two Business Days
of receipt of Non-Defaulting Party's calculation thereof, provide to the
Non-Defaulting Party a detailed written explanation of the basis for such
dispute; provided, however, that if the Net Settlement Amount is due from the
Defaulting Party, the Defaulting Party must nonetheless pay the Net Settlement
Amount by the deadline described in Section 11.6. Notwithstanding the foregoing,
nothing in this Section 11 shall be construed to restrict or preclude the Party
to whom the Net Settlement Amount is owed from realizing on Performance
Assurance held by such Party at any time upon and during the continuance of an
Event of Default with respect to the other Party, notwithstanding (and without
awaiting the outcome of) any dispute as to the Net Settlement Amount.

SECTION 12. FORCE MAJEURE

12.1 Except with regard to a Party's obligation to make any payment due under
this Contract, neither Party shall be liable to the other for failure to perform
its obligation to deliver or receive Gas under this Contract, to the extent such
failure was caused by Force Majeure. The term "Force Majeure" means any cause or
event not reasonably within the control of the Party claiming suspension and not
due to the fault or negligence of such Party, including without limitation, (i)
physical events such as acts of God, landslides, lightning, earthquakes, fires,
hurricanes, storms, floods, washouts, explosions, breakage or accident or
necessity of repairs to facilities, machinery, equipment or lines of pipe; (ii)
weather related events affecting an entire geographic region, such as low
temperatures which cause freezing or failure of wells or lines of pipe; (iii)
interruption and/or curtailment of Firm transportation and/or storage by
Transporters; (iv) acts of others such as strikes, lockouts or other industrial
disturbances, riots, sabotage, insurrections, wars or acts of terrorism; (v)
governmental actions such as necessity for compliance with any court order, Law
or policy having the effect of law promulgated by a Government Agency having
jurisdiction, (vi) any event, action or circumstance described in the preceding
clauses (i) through (v) which impacts the Elba Island LNG Terminal; and (vii)
any port closure, weather related events or acts of others that impede the
unloading, storage or revaporization of LNG at the Elba Island LNG Terminal.

12.2 Notwithstanding anything to the contrary in Section 12.1, neither Party
shall be entitled to claim Force Majeure with respect to a failure to fulfill
its obligation to deliver or receive Gas hereunder to the extent such failure
was caused by any or all of the following circumstances: (i) the curtailment of
interruptible or secondary Firm transportation (unless primary, in-path, Firm
transportation is also curtailed); (ii) economic hardship, to include, without
limitation, Seller's ability to sell Gas at a higher or more advantageous price
than the Contract Price, or Buyer's ability to purchase Gas at a lower or more
advantageous price than the Contract Price; (iii) any event or circumstance
affecting the supply, extraction, production, or transportation of LNG, which
such event or circumstance occurs upstream of the sea buoy identified as "RW "T"
Mo(A) WHIS (the "Sea Buoy") which is located just East of the mouth of the
Savannah River Channel (which shall specifically include any event or
circumstance that affects foreign liquefaction facilities, LNG shipping or other
facilities, pipes, other transportation facilities, and/or LNG supply, in each
case to the extent such event or circumstance occurs upstream of the Sea Buoy);
(iv) acts of others such as strikes, lockouts or other industrial disturbances,
riots, sabotage, insurrections, wars or acts of terrorism that occur other than
on United States soil; or (v) governmental actions by any agency or authority
outside of the United States.

12.3 A Party shall not be entitled to claim Force Majeure and shall not be
relieved of its obligations to deliver or receive Gas hereunder unless such
Party has made reasonable efforts to avoid the adverse impacts of the event(s)
or circumstance(s) constituting Force Majeure and resolve such event(s) or
circumstance(s) in an effort to resume performance. In an event of Force Majeure
(including an event of Force Majeure that affects the Elba Island LNG Terminal),
the Party claiming excuse shall have no obligation to seek alternate Gas or LNG
supplies in order to satisfy any obligation hereunder; provided, however, that
in the case of Force Majeure affecting Seller's performance, Seller shall be
required to deliver to Buyer Gas owned by Seller then available in storage at
the Elba Island LNG Terminal on a pro-rated basis with Seller's other customers,
irrespective of the economic impact to Seller. Buyer


                                       13

Gas Sale and Purchase Contract (December 1, 2004)
<PAGE>
acknowledges that, with respect to sales of Gas by Seller, it is anticipated
that such Gas will primarily be derived from LNG that Seller or its affiliates
import through the Elba Island LNG Terminal.

12.4 Seller shall have the right to sell and deliver to third parties any
quantities of Gas which Buyer has notified Seller it is unable to receive due to
an event of Force Majeure, throughout the duration of the period stipulated in
such Notice as the period during which Buyer will be unable to receive such
quantities of Gas.

12.5 Notwithstanding anything to the contrary herein, the Parties agree that the
settlement of strikes, lockouts or other industrial disturbances that occur
within the United States shall be within the sole discretion of the Party
experiencing such disturbance.

12.6 The Party whose performance is prevented by Force Majeure must provide
Notice to the other Party as soon as practicable after discovery of the event or
circumstance constituting Force Majeure. Initial notice may be given orally;
however, written Notice with reasonably full particulars of the event or
occurrence is required as soon thereafter as reasonably possible. Except as
specifically provided in Section 12.7, upon providing written Notice of Force
Majeure to the other Party, the affected Party shall be relieved of its
obligation to make or accept delivery of Gas, as applicable, from the onset of
the Force Majeure event, but only to the extent that the event or circumstance
constituting Force Majeure is the direct cause of such Party's inability to
perform its obligations, and only with respect to the portion of the Contract
Quantity which cannot be delivered or received due to the Force Majeure. To the
extent a Force Majeure claim is valid pursuant to this Section 12, neither Party
shall be deemed to have failed in any payment obligation related to the portion
of the Contract Quantity which cannot be delivered or received due to the Force
Majeure.

12.7 Upon receiving written Notice of Force Majeure from the Party affected
thereby, the Party not affected by the Force Majeure shall notify any affected
Transporters and make any necessary adjustments to nominations to account for
any changes in quantities to be delivered or received. Such nomination changes
shall be made by the non-affected Party as soon as practicable after receipt of
written Notice of Force Majeure from the affected Party, but in no event later
than 5:00 p.m. of the next following Business Day after receipt of the Notice.

12.8 The performing Party shall have the right to terminate this Contract upon
60 days prior written Notice to the non-performing Party, without any liability
to such performing Party under this Contract (except any outstanding liability
for performance rendered), if due to the occurrence of Force Majeure, the
non-performing Party is unable to perform its obligations for a period of 730
consecutive Days.

12.9 In the event Seller institutes any curtailments due to events or
circumstances that would constitute Force Majeure hereunder, deliveries of Gas
to Buyer under this Contract shall be allocated ratably by Seller with
deliveries to Seller's other customers (i) whose deliveries are also excused by
such Force Majeure, and (ii) which are also supplied on a firm basis with gas
from the Elba Island LNG Terminal delivered to a primary point of receipt in
Southern's Zone 3. Seller shall allocate deliveries ratably based on the
applicable contract volumes of this Contract and such other customers.

SECTION 13. UNEXCUSED FAILURE TO DELIVER/RECEIVE GAS; REMEDY

13.1 Except as set forth in Section 11.1(xii) above, if Seller fails to deliver
or Buyer fails to receive Gas during a particular Day and such is not excused
pursuant to Section 12 of this Contract, the sole and exclusive remedy of the
performing Party shall be recovery of the following:

     (i) in the event of a breach by Seller to deliver Gas during such Day,
     payment by Seller to Buyer in an amount equal to (A) the positive
     difference, if any, between the purchase price paid by Buyer utilizing the
     Cover Standard minus the Contract Price applicable to such Day, adjusted
     for commercially reasonable differences in transportation costs to or from
     the Delivery Point(s), multiplied

     difference, if any, between the Contract Price applicable to such Day minus

rates for South Georgia incremental service are rolled into Southern's FT Zone 3
rate, and (ii) Seller is able to transfer its primary delivery point for such
firm transportation to the Suwannee Project on the South Georgia lateral (the
"Suwannee Project Delivery Point"), then in such case the Call Option Delivery
Point shall be deemed to be the Suwannee Project Delivery Point.

"Firm Transportation" means firm capacity entitlements held by Seller on the
first and/or second phase(s) of the Cypress Pipeline ("Phase I") and ("Phase
II") respectively from the Elba Island LNG Terminal to an interconnection with
Florida Gas Transmission Company, with the Call Option Delivery Point in
Seller's primary transportation path.

"Suwannee Project" means a combined-cycle, gas-fired electric generating unit
that is constructed by Buyer during the Term of this Contract and that is
located at or within very close proximity to Buyer's existing Suwannee plant
site.

17.2 Buyer's First Call Option and Second Call Option Related To Gas Supply and
     Firm Transportation For Suwannee Projects.

     (a) Subject to the conditions set forth in this Section 17, Buyer shall
have the option to purchase from Seller on a Firm basis, and, if such option is
properly exercised, Seller agrees to sell to Buyer, up to [*] MMBtu/day (but no
less than [*] MMBtu/day) of Gas ("Buyer's First Call Option") to supply gas for
the Suwannee Project; provided, however, that Seller may elect to reduce the
quantity of Buyer's First Call Option by up to [*] MMBtu/day upon notice to
Buyer within thirty (30) days of Buyer's election to exercise Buyer's First Call
Option. In addition, Buyer shall have the right to purchase from Seller on a
Firm basis, and if such option is properly exercised, Seller agrees to sell to
Buyer, up to an additional [*] MMBtu/day (but no less than [*] MMBtu/day) of Gas
("Buyer's Second Call Option"); provided, however, that Seller may elect to
reduce the quantity of Buyer's Second Call Option by up to [*] MMBtu/day upon

Second Call Option. Buyer's First Call Option and Buyer's Second Call Option may
be referred to herein individually as a "Call Option" and collectively as the
"Call Options".

     (b) Buyer must notify Seller of its exercise of Buyer's First Call Option
by no later than [*]. If Buyer exercises Buyer's First Call Option, Buyer shall
diligently pursue an order from the Florida Public Service Commission ("FPSC")
for a determination of the need for the Suwannee Project or waive such
requirement within five (5) days of exercising such Call Option. If the FPSC
rejects Buyer's request for such determination, Buyer may withdraw its exercise

thereunder after [*] if the FPSC fails to issue an order approving the Suwannee
Project, unless Buyer elects to waive all conditions precedent relating to such
approval. Buyer must notify Seller of its exercise of Buyer's Second Call Option

<PAGE>
the second phase of the Cypress Pipeline ("Phase II"), then Buyer must notify
Seller of its exercise of Buyer's Second Call Option no later than [*].

     (c) To the extent Buyer exercises either of the Call Options, Seller agrees
to sell and deliver, and Buyer agrees to purchase from Seller, the Gas at the
Call Option Delivery Point. The price with respect to each delivery Day during a
particular Month shall be [*].

     (d) To the extent that Buyer exercises either of the Call Options, Buyer
may elect to relocate the Call Option Delivery Point to the Primary Delivery

prearranged basis at the maximum applicable rate for such Firm Transportation as
reflected in Southern's tariff for Phase I and/or Phase II, as applicable, for a
quantity and duration equal to the term and the quantity of Gas to be purchased
pursuant to the applicable Call Option(s). If Buyer elects to relocate the Call
Option Delivery Point, the Call Option Price shall be reduced by [*].

     (e) To the extent Buyer exercises either of the Call Options, the sale of
Gas shall be for a term expiring on the later of (i) 20 years after the
in-service date of Phase I, or (ii) in the event Seller acquires capacity on
Phase II in connection with the exercise of either the Buyer's First Call Option
and/or Buyer's Second Call Option, 20 years after the in-service date of Phase
II. The sale of Gas shall commence on the later of (a) the in-service date of
Phase I, or (b) the date specified in Buyer's notice exercising either the
Buyer's First Call Option and/or Buyer's Second Call Option; provided that,
unless otherwise agreed, Buyer must specify a date [*] following delivery of
such notice of exercise. Except as set forth in this Section 17, the terms and
conditions of the purchase and sale of any Gas pursuant to the exercise of a
Call Option shall be consistent with the agreed terms and conditions of the
purchase and sale of the Contract Quantity.

     (f) If, prior to the exercise of either the Buyer's First Call Option or
the Buyer's Second Call Option, Seller has committed to firm natural gas sales
and transportation arrangements or stand-alone transportation arrangements under
Phase I or Phase II ("Additional Sales") that result, at any time during which
such Call Options could be exercised by Buyer, in Seller having availability of
less than [*] MMBtu/day of Firm Transportation on Phase II, Buyer's right to
exercise either Call Option shall be limited to Seller's remaining available
Firm Transportation. If (i) Buyer fails to exercise Buyer's First Call Option or
withdraws its exercise of Buyer's First Call Option, (ii) Seller elects not to
acquire capacity on Phase II, and (iii) prior to the exercise of Buyer's Second
Call Option, Seller has committed to Additional Sales that result, at any time
during which such Buyer's Second Call Option could be exercised, in Seller
having availability of less than [*] MMBtu/day of Firm Transportation on Phase
I, then Buyer's right to exercise Buyer's Second Call Option shall be limited
Seller's remaining available Firm Transportation. Seller shall notify Buyer of
any bona fide contractual offers from a third party that is not affiliated with
Seller for Additional Sales with a term in excess of [*]. Buyer shall have the
right, exercisable within sixty (60) days of delivery of such notice, to elect
to purchase gas and transportation capacity or transportation capacity (in the
case of a transportation-only arrangement) from Seller on the same terms and
conditions as specified therein. [*]. Seller represents and warrants to Buyer
that as of the Effective Date, there are no Additional Sales other than those
existing sales to [*]. Buyer acknowledges that the existence of [*] right under
[*],

whether or not exercised, constitutes an "Additional Sale." Seller shall
promptly provide Notice to Buyer [*].

     (g) If Buyer is prevented from exercising either the Buyer's First Call
Option or Buyer's Second Call Option pursuant to Section 17.2(f), Buyer may
request that Seller release the Firm Transportation associated with such Call
Option. Upon Buyer's request, Seller shall permanently release to Buyer such
Firm Transportation if both of the following conditions have been satisfied: (i)
Seller does not require the Firm Transportation in order to perform its
obligations pursuant to its agreements for Additional Sales and (ii) Seller is
permitted pursuant to applicable FERC policy and Southern's FERC Gas Tariff to
release the capacity at a transportation rate equal to Seller's negotiated
transportation rate. If Seller is not permitted pursuant to applicable FERC
policy and Southern's FERC Gas Tariff to release the Firm Transportation to
Buyer at a rate equal to Seller's negotiated transportation rate, then Buyer and
Seller shall work together to agree upon an alternative arrangement that will
put the Parties in the same economic position.

     (h) For any release of Firm Transportation hereunder, Seller shall submit a
request to Southern to release the Firm Transportation to Buyer on a prearranged
basis at a rate equal to the negotiated rate set forth in Seller's
transportation agreement with Southern; provided, however, that, if the
negotiated rate is less than the applicable maximum rate set forth in Southern's
FERC Gas Tariff, Buyer shall be solely responsible for matching any bid by a
competing shipper for the Firm Transportation above the negotiated rate. If
Buyer is required to bid a rate that is higher than Seller's negotiated rate in
order to acquire the Firm Transportation, Seller shall reimburse Buyer for the
difference to the extent that such reimbursement is permitted under applicable
FERC policy and Southern's FERC Gas Tariff. The term of any release of Firm
Transportation hereunder shall be as set forth in Section 17.2(e). If Seller is
not permitted pursuant to applicable FERC policy and Southern's FERC Gas Tariff
to reimburse Buyer for the difference between the rate bid by Buyer in order to
acquire the Firm Transportation and Seller's negotiated rate, then Buyer and
Seller shall work together to agree upon an alternative arrangement that will
put the Parties in the same economic position.

     (i) At any time after the exercise of the option described in this Section
17.2, the Parties may agree, pursuant to the procedures set forth in Section
3.5, to change the Suwannee Gas Contract Price for such Month to either a fixed
dollar amount per MMBtu, or a price based on another index (other than the
Inside FERC index referenced above), in either case as mutually agreed by the
Parties.

     (j) If Seller notifies Southern at any time that it desires to acquire
capacity on Phase II, Seller shall notify Buyer thereof within thirty (30) Days
of Seller's notice to Southern.

17.4 Buyer's Representations Related To The Next Power Project.  Buyer shall not
accept, propose, or enter into any gas supply contract or similar arrangement in
connection with the Next Power Project that, if effective, would prevent Seller
from supplying the Requirements of the Next Power Project (up to [*] MMBtu/day
of Gas) pursuant to Section 17.3 above. Buyer represents and warrants as of the

limitation, all information related to the Contract Price and the Contract
Quantity. Buyer shall inform Seller within two Business Days if the Florida
Public Service Commission denies Buyer's request to keep such information
confidential for such period. In such event, Seller shall have the right to
immediately terminate this Contract by written notice to Buyer. During the Term
of this Contract, at Seller's request, Buyer shall cooperate with Seller to
petition the Florida Public Service Commission for extension of the confidential
treatment of the information related to the Contract Price and the Contract

19.11 Market Disruption Affecting Price Source.  The following provisions shall
be applicable where the Contract Price is determined by reference to a
third-party information source or with respect to instances in which the Spot
Price is applied:

     19.11.1 Market Disruption.  If a Market Disruption Event (as defined below)
occurs during the Determination Period (as defined below), the Floating Price
(as defined below) for the affected Trading Day(s) (as defined below) shall be
determined pursuant to the Floating Price for the first Trading Day thereafter
on which no Market Disruption Event exists; provided, however, that if the
Floating Price is not so determined within three Business Days after the first
Trading Day on which the Market Disruption Event occurred or existed, then the
Parties shall negotiate in good faith to agree on a Floating Price (or a method
for determining a Floating Price), and if the Parties have not so agreed on or
before the 12th Business Day following the first Trading Day on which the Market
Disruption Event occurred or existed, then the Floating Price shall be
determined in good faith by Buyer by taking the average of two or more dealer
quotes. "Market Disruption Event" means, with respect to any Price Source (as
defined below), any of the following events (the existence of which shall be
determined in good faith by Buyer): (i) the failure of the Price Source to
announce or publish information necessary for determining the Floating Price;
(ii) the failure of trading to commence or the permanent discontinuation or
material suspension of trading in the relevant options contract or commodity on
the Exchange (as defined below) or in the market specified for determining a
Floating Price; (iii) the temporary or permanent discontinuance or
unavailability of the Price Source (iv) the temporary or permanent closing of
any Exchange specified for determining a Floating Price; or (v) a material
change in the formula for the method of determining the Floating Price. "Price
Source" means the publication (or such other origin of reference, including an
Exchange) containing (or reporting) the specified price (or prices from which
the specified price is calculated). "Floating Price" means the Contract Price
that is based upon a Price Source. "Exchange" means, in respect of a price, the
exchange or principal trading market specified in the calculation of such price.
"Determination Period" means each calendar Month, a part or all of which is
within the delivery period during which the relevant price applies. "Trading
Day" means a day in respect of which the relevant Price Source published the
Floating Price.

     19.11.2 Corrections to Published Prices.  For purposes of determining the
relevant prices for any Day, if the price published or announced on a given Day
and used or to be used to determine a relevant price is subsequently corrected
and the correction is published or announced by the person responsible for that
publication or announcement, either Party may notify the other Party of (i) that
correction and (ii) the amount (if any) that is payable as a result of that
correction. If a Party gives notice that an amount is so payable, the Party that
originally either received or retained such amount will, not later than two
Business Days after the effectiveness of that notice, pay, subject to any
applicable conditions precedent, to the other Party that amount, together with
interest at a rate equal to the lower of (x) the then-effective prime rate of
interest published under "Money Rates" by The Wall Street Journal; or (y) the
maximum applicable lawful interest rate, for the period from and including the
day on which payment originally was (or was not) made to but excluding the day
of payment of the refund or payment resulting from that correction.

     19.11.3 Calculation of Floating Price.  For the purposes of the calculation
of a Floating Price, all numbers shall be rounded to three decimal places. If
the fourth decimal number is five or greater, then the third decimal number
shall be increased by one, and if the fourth decimal number is less than five,
then the third decimal number shall remain unchanged.

19.12 Construction.  The language used in this Contract is the product of both
Parties' efforts and each Party hereby irrevocably waives the benefit of any
rule of contract construction which disfavors the drafter of a contract or the
drafter of specific language in a contract.

19.13 Recording.  The Parties agree that each Party may electronically record
all telephone conversations with respect to this Contract between their
respective employees, without any special or further notice to the other Party.
Each Party shall obtain any necessary consent of its agents and employees to
such recording. Each Party waives any objections to the introduction of the
recorded conversations into evidence in any proceeding based on the Statute of
Frauds, the parol evidence rule, or the best evidence rule. Each Party waives
any objection or defense to its authority or the authority of its employee
provided that such employee can be identified on the relevant employing Party's
recording. No Party may knowingly destroy or erase a recording once the
possessing Party becomes aware of an actual dispute in which the recording may
reasonably be anticipated to be discoverable.

19.14 Independent Contractors.  The Parties are independent contractors. Nothing
contained in this Contract shall be deemed to create an association, joint
venture, partnership or principal/agent relationship between the Parties hereto
or to impose any partnership obligation or liability on either Party. Neither
Party shall have any right, power or authority hereunder to enter into any
agreement or commitment, act on behalf of, or otherwise bind the other Party in
any way.

19.15 Survival.  The rights of either Party pursuant to Sections 7, 8.3, 11,
19.10 and any other provision(s) of this Contract that expressly or by
implication comes into or remains in force following the termination or
expiration of this Contract shall survive the termination or expiration of this
Contract.

19.16 Imaged Agreement.  Any original executed counterpart of this Contract, or
other related document may be photocopied and stored on computer tapes and disks
(the "Imaged Agreement"). The Imaged Agreement, if introduced as evidence on
paper, a tape or other electronic recording of an oral agreement to a Price
Change made pursuant to Section 3.4 (the "Transaction Tape"), if introduced as
evidence in its original form and as transcribed onto paper, and all computer
records of the foregoing, if introduced as evidence in printed format, in any
judicial, arbitration, mediation or administrative proceedings, will be
admissible as between the Parties to the same extent and under the same
conditions as other business records originated and maintained in documentary
form. Neither Party shall object to the admissibility of the Transaction Tape,
or the Imaged Agreement (or photocopies of the transcription of the Transaction
Tape, or the Imaged Agreement) on the basis that such were not originated or
maintained in documentary form under the hearsay rule, the best evidence rule,
or the parol evidence rule.

19.17 Counterparts.  This Contract may be executed in several counterparts, and
all such counterparts shall constitute one agreement binding on both Parties
hereto and shall have the same force and effect as an original instrument.

     that, the Collateral Requirement of a Party will be deemed to be zero (0)
     whenever the calculation of such Party's Collateral Requirement yields a

2.3 DELIVERY OF PERFORMANCE ASSURANCE.  On any Calculation Date on which (a) no
Event of Default has occurred and is continuing with respect to the Secured
Party, (b) no Early Termination Date has occurred or been designated as a result

any unsatisfied payment Obligations, and (c) the Pledging Party's Collateral
Requirement equals or exceeds its Minimum Transfer Amount, then the Secured
Party may demand that the Pledging Party Transfer to the Secured Party, and the
Pledging Party shall, after receiving such notice from the Secured Party,
Transfer, or cause to be Transferred to the Secured Party, Performance Assurance
for the benefit of the Secured Party, having a Collateral Value at least equal
to the Pledging Party's Collateral Requirement. The amount of Performance
Assurance required to be Transferred hereunder shall be rounded up to the
nearest integral multiple of the Rounding Amount. Unless otherwise agreed in
writing by the Parties, (i) Performance Assurance demanded of a Pledging Party
on or before the Notification Time


                                       28

Gas Sale and Purchase Contract (December 1, 2004)
<PAGE>
shall be provided by the close of business on the next Local Business Day and
(ii) Performance Assurance demanded of a Pledging Party after the Notification
Time shall be provided by the close of business on the second Local Business Day
thereafter. Any Letter of Credit shall be Transferred to such address as the
Secured Party shall specify and any such demand made by the Secured Party
pursuant to this CSA shall specify account information for the account to which
Performance Assurance in the form of Cash shall be Transferred. Failure by the
Pledging Party to comply with the provisions of this Section 2.3 shall
constitute an Event of Default pursuant to Section 11 of the Contract.

2.4 ENCUMBRANCE; GRANT OF SECURITY INTEREST.  As security for the prompt and
complete payment of all amounts due or that may now or hereafter become due from
a Party to the other Party and the performance by a Party of all covenants and
obligations to be performed by it pursuant to this CSA, the Contract and any
other documents, instruments or agreements executed in connection therewith
(collectively, the "OBLIGATIONS"), each Party hereby pledges, assigns, conveys
and transfers to the other Party, and hereby grants to the other Party a present
and continuing security interest in and to, and a general first lien upon and
right of set off against, all Performance Assurance which has been or may in the
future be Transferred to, or received by, the other Party and/or its Custodian,
and all dividends, interest, and other proceeds from time to time received,
receivable or otherwise distributed in respect of, or in exchange for, any or
all of the foregoing and each Party agrees to take such action as the other
Party reasonably requests in order to perfect the other Party's continuing
security interest in, and lien on (and right of setoff against), such
Performance Assurance.

2.5 REDUCTION AND SUBSTITUTION OF PERFORMANCE ASSURANCE.

     (a) On any Local Business Day (but no more frequently than weekly with
respect to Letters of Credit and daily with respect to Cash), a Pledging Party
may request a reduction in the amount of Performance Assurance previously
provided by the Pledging Party for the benefit of the Secured Party, provided
that, after giving effect to the requested reduction in Performance Assurance,
(i) the Pledging Party shall in fact have a Collateral Requirement of zero, and
(ii) no Event of Default with respect to the Pledging Party shall have occurred
and be continuing. A permitted reduction in Performance Assurance may be
effected by the Transfer of Cash to the Pledging Party or the reduction of the
amount of an outstanding Letter of Credit previously issued for the benefit of
the Secured Party. The amount of Performance Assurance required to be reduced
hereunder shall be rounded down to the nearest integral multiple of the Rounding
Amount. The Pledging Party shall have the right to specify the means of
effecting the reduction in Performance Assurance. In all cases, the cost and
expense of reducing Performance Assurance (including, but not limited to, the
reasonable costs, expenses, and attorneys' fees of the Secured Party) shall be
borne by the Pledging Party. Unless otherwise agreed in writing by the Parties,
(i) if the Pledging Party's reduction demand is made on or before the
Notification Time, then the Secured Party shall have one (1) Local Business Day
to effect a permitted reduction in Performance Assurance and (ii) if the
Pledging Party's reduction demand is made after such time on a Local Business
Day, then the Secured Party shall have two (2) Local Business Days to effect a
permitted reduction in Performance Assurance, in each case, if such reduction is
to be effected by the return of Cash to the Pledging Party. If a permitted
reduction in Performance Assurance is to be effected by a reduction in the
amount of an outstanding Letter of Credit previously issued for the benefit of
the Secured Party, the Secured Party shall promptly take such action as is
reasonably necessary to effectuate such reduction.

     (b) Except when an Event of Default with respect to the Pledging Party
shall have occurred and be continuing, the Pledging Party may substitute
Performance Assurance for other existing Performance Assurance of equal
Collateral Value upon two (2) Local Business Day's written notice to the Secured
Party; provided, however, that if such substitute Performance Assurance is of a
type not otherwise approved by this CSA, then the Secured Party must consent to
such substitution. Upon the Transfer to the Secured Party and/or its Custodian
of the substitute Performance Assurance, the Secured Party and/or its Custodian
shall Transfer the relevant replaced Performance Assurance to the Pledging Party
within two (2) Local Business Days. Notwithstanding anything herein to the
contrary, no such substitution shall be permitted unless (i) the substitute
Performance Assurance is Transferred simultaneously or has been Transferred to
the Secured Party and/or its Custodian prior to the release of the Performance
Assurance to be returned to the Pledging Party and the security interest in, and
general first lien upon, such substituted Performance Assurance granted pursuant
hereto in favor of the Secured Party shall have been perfected as required by
applicable law and shall constitute a first priority perfected security interest
therein and general first lien thereon, and (ii) after giving effect to such
substitution, the Collateral Value of such substitute Performance Assurance
shall not be materially diminished. Each substitution of Performance Assurance
shall constitute a representation and warranty by the Pledging Party that the
substituted Performance Assurance shall be subject to and governed by the terms
and conditions of this CSA, including without limitation the security interest
in, general first lien on and right of offset against, such substituted
Performance Assurance granted pursuant hereto in favor of the Secured Party
pursuant to Section 2.4.

     (c) The Transfer of any Performance Assurance by the Secured Party and/or
its Custodian in accordance with this Section 2.5 shall be deemed a release by
the Secured Party of its security interest, general first lien and right of
offset granted pursuant to Section 2.4 hereof only with respect to such returned
Performance Assurance. In connection with each Transfer of any Performance
Assurance pursuant to this Section 2.5, the Pledging Party will, upon request of
the Secured Party, execute a receipt showing the Performance Assurance
Transferred to it.

2.6 ADMINISTRATION OF PERFORMANCE ASSURANCE.

     (a) Cash.  Performance Assurance provided in the form of Cash to a Party
that is the Secured Party shall be subject to the following provisions:

     (i) A Party shall be entitled to hold Performance Assurance in the form of
Cash provided that the following conditions are satisfied: (i) no Event of
Default has occurred and is continuing with respect to it; and (ii) Cash shall
be held only in any jurisdiction within the United States.

     (ii) If such Party is entitled to hold Cash, then it will be entitled to
hold Cash or to appoint an agent which is a Qualified Institution (a
"CUSTODIAN") to hold Cash for it. If such Party is not entitled to hold Cash,
then the provisions of Section 2.6(a)(iii) shall not apply with respect to such
Party and Cash shall be held in a Qualified Institution in accordance with the
provisions of Section 2.6(a)(iii)(B). Upon notice by the Secured Party to the
Pledging Party of the appointment of a Custodian, the Pledging Party's
obligations to make any Transfer will be discharged by making the Transfer to
that Custodian. The holding of Cash by a Custodian will be deemed to be the
holding of Cash by the Secured Party for which the Custodian is acting. If the
Secured Party or its Custodian fails to satisfy any conditions for holding Cash
as set forth above or if the Secured Party is not entitled to hold Cash at any
time, then the Secured Party will Transfer, or cause its Custodian to Transfer,
the Cash to a Qualified Institution and the Cash shall be maintained in
accordance with Section 2.6(a)(iii)(B), with the Party not eligible to hold Cash
being considered the "DOWNGRADED PARTY" (as defined below). Except as set forth
in Section 2.6(c), the Secured Party will be liable for the acts or omissions of
its Custodian to the same extent that the Secured Party would be liable
hereunder for its own acts or omissions.

     (iii) Use of Cash.  Notwithstanding the provisions of applicable law, if no
Event of Default has occurred and is continuing with respect to the Secured
Party, then the Secured Party shall have the right to sell, pledge,
rehypothecate, assign, invest, use, commingle or otherwise use in its business
any Cash that it holds as Performance Assurance hereunder, free from any claim
or right of any nature whatsoever of the Pledging Party, including any equity or
right of redemption by the Pledging Party; provided, however, that if a Party or
its Custodian is not eligible to hold Cash pursuant to Section 2.6(a) (such
Party shall be the "DOWNGRADED PARTY" and the event that caused it or its
Custodian to be ineligible to hold Cash shall be a "CREDIT RATING EVENT") then:

          (A) the provisions of this Section 2.6(a)(iii) will not apply with
     respect to the Downgraded Party; and

          (B) the Downgraded Party shall be required to Transfer (or cause to be
     Transferred) not later than the close of business on the next Local
     Business Day following such Credit Rating Event all Cash in its possession
     or held on its behalf to a Qualified Institution approved by the
     non-Downgraded Party (which approval shall not be unreasonably withheld),
     to a segregated, safekeeping or custody account (the "COLLATERAL ACCOUNT")
     within such Qualified Institution with the title of the account indicating
     that the property contained therein is being held as Cash for the
     Downgraded Party. The Qualified Institution shall serve as Custodian with
     respect to the Cash in the Collateral Account, and shall hold such Cash in
     accordance with the terms of this CSA and for the security interest of the
     Downgraded Party and execute such account control agreements as are
     necessary or applicable to perfect the security interest of the
     non-Downgraded Party therein pursuant to Section 9-314 of the Uniform
     Commercial Code or otherwise, and subject to such security interest, for
     the ownership and benefit of the non-Downgraded Party. The Qualified
     Institution holding the Cash will invest and reinvest or procure the
     investment and reinvestment of the Cash in accordance with the written
     instructions of the Pledging Party, subject to the approval of such
     instructions by the Downgraded Party (which approval shall not be
     unreasonably withheld), provided that the Qualified Institution shall not
     be required to so invest or reinvest or procure such investment or
     reinvestment if an Event of Default with respect to the Pledging Party
     shall have occurred and be continuing. The Downgraded Party shall have no
     responsibility for any losses resulting from any investment or reinvestment
     effected in accordance with the Pledging Party's instructions.

     (iv) Interest Payments on Cash.  So long as no Event of Default with
respect to the Pledging Party has occurred and is continuing, and to the extent
that an obligation to Transfer Performance Assurance would not be created or
increased by the Transfer, in the event that the Secured Party or its Custodian
is holding Cash, the Secured Party will Transfer (or caused to be Transferred)
to the Pledging Party, in lieu of any interest or other amounts paid or deemed
to have been paid with respect to such Cash (all of which may be retained by the
Secured Party or its Custodian), the Interest Amount. The Pledging Party shall
invoice the Secured Party monthly setting forth the calculation of the Interest
Amount due, and the Secured Party shall make payment thereof by the later of (A)
the third Local Business Day of the first month after the last month to which
such invoice relates or (B) the third Local Business Day after the day on which
such invoice is received. On or after the occurrence of an Event of Default with
respect to the Pledging Party, the Secured Party or its Custodian shall retain
any such Interest Amount as additional Performance Assurance hereunder for so
long as such Event of Default is continuing.

(b) Letters of Credit.  Performance Assurance provided in the form of a Letter
of Credit shall be subject to the following provisions.

     (i) Unless otherwise agreed to in writing by the Parties, each Letter of
Credit shall be provided in accordance with Section 2.3, and each Letter of
Credit shall be maintained for the benefit of the Secured Party. The Pledging
Party shall (A) renew or cause the renewal of each outstanding Letter of Credit
on a timely basis as provided in the relevant Letter of Credit, (B) if the bank
that issued an outstanding Letter of Credit has indicated its intent not to
renew such Letter of Credit, provide either a substitute Letter of Credit or
other form of Performance Assurance, in each case at least twenty (20) Local
Business Days prior to the expiration of the outstanding Letter of Credit, and
(C) if a bank issuing a Letter of Credit shall fail to honor the Secured Party's
properly documented request to draw on an outstanding Letter of Credit, provide
for the benefit of the Secured Party either a substitute Letter of Credit that
is issued by a bank acceptable to the Secured Party or other form of Performance
Assurance, in each case within one (1) Local Business Day after such refusal,
provided that, as a result of the Pledging Party's failure to perform in
accordance with (A), (B), or (C) above, the Pledging Party would still have an
obligation to provide Performance Assurance hereunder.

     (ii) As one method of providing Performance Assurance, the Pledging Party
may increase the amount of an outstanding Letter of Credit or establish one or
more additional Letters of Credit.

     (iii) Upon the occurrence of a Letter of Credit Default, the Pledging Party
agrees to Transfer to the Secured Party either a substitute Letter of Credit or
other form of Performance Assurance, in each case on or before the first Local
Business Day after the occurrence thereof (or the fifth (5th) Local Business Day
after the occurrence thereof if only clause (a) under the definition of Letter
of Credit Default applies).

     (iv) Upon or at any time after the occurrence and continuation of an Event
of Default with respect to the Pledging Party, then the Secured Party may draw
on the entire, undrawn portion of any outstanding Letter of Credit upon
submission to the bank issuing such Letter of Credit of one or more certificates
specifying that such Event of Default has occurred and is continuing. Cash
proceeds received from drawing upon the Letter of Credit shall be deemed
Performance Assurance as security for the Pledging Party's obligations to the
Secured Party and the Secured Party shall have the rights and remedies set forth
in Section 2.7 with respect to such cash proceeds. Notwithstanding the Secured
Party's receipt of Cash proceeds of a drawing under the Letter of Credit, the
Pledging Party shall remain liable (y) for any failure to Transfer sufficient
Performance Assurance or (z) for any amounts owing to the Secured Party and
remaining unpaid after the application of the amounts so drawn by the Secured
Party.

     (v) In all cases, the costs and expenses (including but not limited to the
reasonable costs, expenses, and attorneys' fees of the Secured Party) of
establishing, renewing, substituting, canceling, and increasing the amount of a
Letter of Credit shall be borne by the Pledging Party.

(c) Care of Performance Assurance.  Except as otherwise provided in Section
2.6(a)(iv) and beyond the exercise of reasonable care in the custody thereof,
the Secured Party shall have no duty as to any Performance Assurance in its
possession or control or in the possession or control of any Custodian or any
income thereon or as to the preservation of rights against prior parties or any
other rights pertaining thereto. The Secured Party shall be deemed to have
exercised reasonable care in the custody and preservation of the Performance
Assurance in its possession, and/or in the possession of its agent for
safekeeping, if the Performance Assurance is accorded treatment substantially
equal to that which it accords its own property, and shall not be liable or
responsible for any loss or damage to any of the Performance Assurance, or for
any diminution in the value thereof, by reason of the act or omission of any
Custodian selected by the Secured Party in good faith except to the extent such
loss or damage is the result of such agent's willful misconduct or negligence.
Unless held by a Custodian, the Secured Party shall at all times retain
possession or control of any Performance Assurance Transferred to it. The
holding of Performance

Gas Sale and Purchase Contract (December 1, 2004)
<PAGE>
Assurance by a Custodian for the benefit of the Secured Party shall be deemed to
be the holding and possession of such Performance Assurance by the Secured Party
for the purpose of perfecting the security interest in the Performance
Assurance. Except as otherwise provided in Section 2.6(a)(iii), nothing in this
CSA shall be construed as requiring the Secured Party to select a Custodian for
the keeping of Performance Assurance for its benefit.

2.7 EXERCISE OF RIGHTS AGAINST PERFORMANCE ASSURANCE.

     (a) In the event that an Event of Default with respect to the Pledging
Party has occurred and is continuing, the Secured Party may exercise any one or
more of the rights and remedies provided under the Contract, in this CSA, or as
otherwise available under applicable law. Without limiting the foregoing, if at
any time an Event of Default with respect to the Pledging Party has occurred and
is continuing, then the Secured Party may, in its sole discretion, exercise any
one or more of the following rights and remedies:

     (i)  all rights and remedies available to a secured party under the Uniform
          Commercial Code and any other applicable jurisdiction and other
          applicable laws with respect to the Performance Assurance held by or
          for the benefit of the Secured Party;

     (ii) the right to set off any Performance Assurance held by or for the
          benefit of the Secured Party against and in satisfaction of any amount
          payable by the Pledging Party in respect of any of its Obligations;

     (iii) the right to draw on any outstanding Letter of Credit issued for its
          benefit; and/or

     (iv) the right to liquidate any Performance Assurance held by or for the
          benefit of the Secured Party through one or more public or private
          sales or other dispositions with such notice, if any, as may be
          required by applicable law, free from any claim or right of any nature
          whatsoever of the Pledging Party, including any right of equity or
          redemption by the Pledging Party (with the Secured Party having the
          right to purchase any or all of the Performance Assurance to be sold)
          and to apply the proceeds from the liquidation of such Performance
          Assurance to and in satisfaction of any amount payable by the Pledging
          Party in respect of any of its Obligations in such order as the
          Secured Party may elect.

     (b) The Pledging Party hereby irrevocably constitutes and appoints the
Secured Party and any officer or agent thereof, with full power of substitution,
as the Pledging Party's true and lawful attorney-in-fact with full irrevocable
power and authority to act in the name, place and stead of the Pledging Party or
in the Secured Party's own name, from time to time in the Secured Party's
discretion, for the purpose of taking any and all action and executing and
delivering any and all documents or instruments which may be necessary or
desirable to accomplish the purposes of Section 2.7(a).

     (c) Secured Party shall be under no obligation to prioritize the order with
respect to which it exercises any one or more rights and remedies available
hereunder. The Pledging Party shall in all events remain liable to the Secured
Party for any amount payable by the Pledging Party in respect of any of its
Obligations remaining unpaid after any such liquidation, application and set
off.

     (d) In addition to the provisions of Section 2.7(a), if at any time an
Event of Default with respect to the Secured Party has occurred and is
continuing, then:

     (1) the Secured Party will be obligated immediately to Transfer all
     Performance Assurance (including any Letter of Credit) and the Interest
     Amount, if any, to the Pledging Party;

     (2) the Pledging Party may do any one or more of the following: (x)
     exercise any of the rights and remedies of a pledgor with respect to the
     Performance Assurance, including any such rights and remedies under law
     then in effect; (y) to the extent that the Performance Assurance or the
     Interest Amount is not Transferred to the Pledging Party as required in (1)
     above, setoff amounts payable to the Secured Party against the Performance
     Assurance (other than Letters of Credit) held by the Secured Party or to
     the extent its rights to setoff are not exercised, withhold payment of any
     remaining amounts payable by the Pledging Party, up to the value of any
     remaining Performance Assurance held by the Secured Party, until the
     Performance Assurance is Transferred to the Pledging Party; and (z)
     exercise rights and remedies available to the Pledging Party under the
     terms of any Letter of Credit; and

Gas Sale and Purchase Contract (December 1, 2004)
<PAGE>
(3)  the Secured Party shall be prohibited from drawing on any Letter of Credit
     that has been posted by the Pledging Party for its benefit.

2.8 DISPUTED CALCULATIONS.  If the Pledging Party in good faith disputes the
Secured Party's calculation of the Performance Assurance amount, it will notify
the Secured Party in writing not later than the close of business on the Local
Business Day following the date demand is made and the Pledging Party shall
deliver to the Secured Party the undisputed portion of the Performance Assurance
amount requested within the time period set forth in Section 2.3. Regarding the
disputed portion of the Performance Assurance amount originally requested, the
Parties agree to negotiate in good faith for a period not to exceed four (4)
Local Business Days after the Local Business Day in which such original request
is made to determine the amount of additional Performance Assurance the Pledging
Party shall be required to deliver. By the close of business on such fourth
Local Business Day, the Pledging Party will deliver to the Secured Party the
disputed portion of the Performance Assurance amount in the amount as agreed by
the Parties. If the Parties are unable to agree, then the Pledging Party will
deliver to the Secured Party the disputed portion of the Performance Assurance
amount in the amount originally requested or any lesser amount then requested by
the Secured Party.

If following the four Local Business Day negotiating period the Parties cannot
agree, each Party shall choose and contract for a Qualified Consultant to
calculate the Exposure Amount and notify both Parties of the resulting amount
within eighteen (18) Local Business Days from the last day of the four Local
Business Day negotiating period. The Exposure Amount shall be calculated
independently by each Qualified Consultant. The average of the two resulting
amounts provided by the Qualified Consultants shall be deemed to be the Exposure
Amount. If the Pledging Party provided Performance Assurance in excess of that
required as a result of the calculation of the Qualified Consultants, then the
Secured Party shall return the excess Performance Assurance to the Pledging
Party in accordance with Section 2.5. The Party whose calculation of the
Exposure Amount as of the end of the four Local Business Day negotiating period
differs the most from the average of the calculations performed by the Qualified
Consultants as described above shall be responsible for the reasonable cost of
both Qualified Consultants.

2.9 COVENANTS; REPRESENTATIONS AND WARRANTIES; MISCELLANEOUS.

     (a) The Pledging Party will execute and deliver to the Secured Party (and
to the extent permitted by applicable law, the Pledging Party hereby authorizes
the Secured Party to execute and deliver, in the name of the Pledging Party or
otherwise) such financing statements, assignments and other documents and do
such other things relating to the Performance Assurance and the security
interest granted under this CSA, including any action the Secured Party may deem
necessary or appropriate to perfect or maintain perfection of its security
interest in the Performance Assurance, and the Pledging Party shall pay all
costs relating to its Transfer of Performance Assurance and the maintenance and
perfection of the security interest therein.

represents and warrants that:

     properties, including, without limitation, the Performance Assurance, other
     than the security interests and liens created under the Contract and this
     CSA;

          (ii) upon the Transfer of Performance Assurance by the Pledging Party
     to the Secured Party and/or its Custodian, the Secured Party shall have a
     valid and perfected first priority continuing security interest therein,
     free of any liens, claims or encumbrances, except those liens, security
     interests, claims or encumbrances arising by operation of law that are
     given priority over a perfected security interest; and

          (iii) it is not and will not become a party to or otherwise be bound
     by any agreement, other than the Contract and this CSA, which restricts in
     any manner the rights of any present or future holder of any of the
     Performance Assurance with respect hereto.

     (c) This CSA has been and is made solely for the benefit of the Parties and
their permitted successors and assigns, and no other person, partnership,
association, corporation or other entity shall acquire or have any right under
or by virtue of this CSA.

     (d) The Pledging Party shall pay on request and indemnify the Secured Party
against any taxes (including without limitation, any applicable transfer taxes
and stamp, registration or other documentary taxes), assessments, or charges
that may become payable by reason of the security interests, general first lien
and right of

fees and disbursements of counsel) incurred by the other in connection with the
enforcement of, or suing for or collecting any amounts payable by it under, this
CSA.

     (d) No failure or delay by either Party hereto in exercising any right,
power, privilege, or remedy hereunder shall operate as a waiver thereof.

                                FORM OF GUARANTEE

                                    GUARANTEE

     Guarantee, dated as of ___________, 20__, by BG Energy Holdings Limited, a
company registered in England and Wales ("Guarantor"), in favor of Florida Power
Corporation, a Florida corporation doing business as Progress Energy Florida,
Inc. ("Beneficiary").

1 Guarantee.  In consideration of Beneficiary entering into that certain Gas
Sale and Purchase Contract dated as of December 1, 2004, as amended and
supplemented from time to time (the "Gas Contract"), between BG LNG Services,
LLC ("Company"), an affiliate of Guarantor, and Beneficiary, Guarantor
irrevocably and unconditionally guarantees to Beneficiary, its successors and
assigns, the prompt payment when due, subject to any applicable grace period
under the Gas Contract, of all present and future amounts payable by Company to
Beneficiary under the Gas Contract (even if such amounts payable are deemed to
be damages) (the "Obligations").Beneficiary may make written demand of Guarantor
for any Obligation not paid by Company when due, subject to applicable grace
periods, and Guarantor shall pay such Obligations within five Business Days (as
such term is defined in the Gas Contract), of receipt of such demand.
Notwithstanding any other provision hereof to the contrary, the maximum amount
payable by Guarantor under this Guarantee shall not exceed US$_____________ in
the aggregate.

2 Nature of Guarantee.  Guarantor's obligations hereunder shall not be affected
by the genuineness, validity, regularity or enforceability of the Obligations or
any instrument evidencing any Obligations, or by the existence, validity,
enforceability, perfection, or extent of any collateral therefor or by any other
event, occurrence or circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor or surety other than the defense
of payment by Company or Guarantor. Beneficiary makes no representation or
warranty in respect of any such circumstance and has no duty or responsibility
whatsoever to Guarantor with respect to the management and maintenance of the
Obligations or any collateral therefor. This Guarantee constitutes a guarantee
of payment when due and not of collection. In the event that any payment of
Company in respect of any Obligations is annulled, set aside, invalidated,
declared to be fraudulent or preferential, rescinded or must otherwise be
returned for any reason whatsoever, Guarantor shall remain liable hereunder with
respect to such Obligations as if such payment had not been made.

3 Consents, Waivers and Renewals.  Without limiting the provisions of Section 1
hereof with respect to the termination of this Guarantee and Guarantor's maximum
liability hereunder, Guarantor agrees that Beneficiary may at any time and from
time to time, either before or after the maturity thereof, without notice to or
further consent of Guarantor, extend the time of payment of, exchange or
surrender any collateral for, or renew any of the Obligations, and may also make
any agreement with Company for the extension, renewal, payment, compromise,
discharge or release thereof, in whole or in part, or for any modification of
the terms thereof or of any agreement between Beneficiary and Company or any
such other party or person, without in any way impairing or affecting this
Guarantee. Guarantor agrees that Beneficiary may resort to Guarantor for payment
of any of the Obligations, whether or not Beneficiary shall have resorted to any
collateral security, or shall have proceeded against any other obligor
principally or secondarily obligated with respect to any of the Obligations.

4 Expenses.  Guarantor agrees to pay on demand all reasonable out-of-pocket
expenses (including the reasonable fees and expenses of Beneficiary's counsel)
in any way relating to the enforcement or protection of the rights of
Beneficiary hereunder; provided, that Guarantor shall not be liable for any
expenses of Beneficiary unless payment is due under this Guarantee.

5 Subrogation.  Guarantor will not exercise any rights which it may acquire by
way of subrogation until all the Obligations to Beneficiary shall have been paid
in full. Subject to the foregoing, upon payment of all the Obligations,
Guarantor shall be subrogated to the rights of Beneficiary against Company, and
Beneficiary agrees to take at Guarantor's expense such steps as the Guarantor
may reasonably request to implement such subrogation.

6 No Waiver; Cumulative Rights.  Without limiting the provisions of Section 1
hereof with respect to the termination of this Guarantee and Guarantor's maximum
liability hereunder, no failure on the part of Beneficiary to exercise, and no
delay in exercising, any right, remedy or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise by Beneficiary of any
right, remedy or power hereunder preclude any other or future exercise of any
right, remedy or power. Each and every right, remedy and power hereby granted to
Beneficiary or allowed it by law or other agreement shall be cumulative and not
exclusive of any other, and may be exercised by Beneficiary from time to time.

7 Waiver of Notice.  Guarantor waives notice of the acceptance of this
Guarantee, presentment, demand, notice of dishonor, protest, notice of any sale
of collateral security and all other notices whatsoever, except for those
expressly required by this Guarantee, and any right to require that any action
or proceeding be brought against Company or any other entity, or except as
expressly hereinabove set forth, to require that Beneficiary seek enforcement of
any performance against Company or any other entity, prior to any action against
Guarantor under the terms hereof.

                      FIRM TRANSPORTATION SERVICE AGREEMENT
                               RATE SCHEDULE FTS-2

4.3  Notwithstanding Section 4.1 above, as of the Service Commencement Date and
     during the primary term of this Agreement, Shipper shall pay Transporter,
     for all services rendered hereunder, unless otherwise agreed by Shipper and
     Transporter, the lower of: (I) the rates established under Transporter's
     Rate Schedule FTS-2 (inclusive of all applicable surcharges), as filed with
     and approved by the FERC and as said Rate Schedule may hereafter be legally
     amended or superseded, or (2) the Final Rate Cap as determined below:

     (a)  The Base Rate Cap shall be as follows: $[*]/MMBtu/d.

     (b)  The Base Rate Cap assumes the levelized rate methodology through March
          31, 2005, and thereafter, the traditional cost of service methodology.
          For purposes of this section with respect to this Agreement, a
          "levelized rate" shall mean a rate designed by adjusting the annual
          depreciation expense such that it results in a levelized cost of
          service.

     (c)  The Base Rate Cap is stated in nominal dollars, and shall exclude all
          applicable surcharges and fuel.

     (d)  Beginning on January 1, 2005, and annually thereafter ("Escalation
          Date"), the Base Rate Cap then in effect shall be escalated in
          accordance with the following formula; provided that in no event shall
          the Base Rate Cap, as it may be escalated pursuant to this subsection
          (d), exceed $[*] per MMBtu. On each Escalation Date, the Base Rate Cap
          to be effective for the subsequent twelve (12) month period shall be
          the sum of: (i) [*] multiplied by the Prior Base Rate Cap, which is
          defined herein as the Base Rate Cap that was effective for the twelve
          (12) month period immediately preceding the Escalation Date, and (ii)
          [*] multiplied by the Prior Base Rate Cap, [*].

     (e)  (i) For any billing month, the Final Rate Cap (stated on a per unit
          basis) shall be determined by adding the Base Rate Cap and an amount
          equal to the aggregate of the applicable surcharges (as defined in
          section (e)(ii) below).

          (ii) The type of surcharges contemplated under Rate Schedule FTS-2 to
               be included in the calculation of the Final Rate Cap are
               applicable surcharges, such as ACA, fuel, and Capital surcharges;
               provided, however, Transporter shall not collect

                      FIRM TRANSPORTATION SERVICE AGREEMENT
                               RATE SCHEDULE FTS-2

               under this Agreement any surcharge associated with GRI, Gas
               Supply Realignment ("GSR"), the recovery of take-or-pay costs or
               gas purchase reformation costs, FERC Account No.191 costs
               ("restructuring costs"), or any similar surcharge associated with
               the restructuring of Transporter's merchant service under orders
               in FERC Docket No. RS92-16-000 or similar proceedings, any
               separately stated surcharge related to the recovery of
               restructuring costs of any upstream provider of transportation or
               sales services to Transporter, or, to the extent such charges may
               be discountable, any industry-wide research and development
               surcharges such as those currently proposed in FERC Docket No.
               RP04-378.

     (f)  If, at any time after the Service Commencement Date and during the
          primary term of this Agreement, the effective rate that Transporter is
          authorized by the FERC to charge Shipper, including surcharges,
          exceeds the Final Rate Cap, then Transporter shall discount such
          authorized FERC rate down to the Final Rate Cap in accordance with the
          order of discounting provided for in Transporter's FERC Gas Tariff.

     (g)  Unless otherwise mutually agreed by the Parties, after the expiration
          of the primary term of this Agreement, Shipper shall pay Transporter
          the rates established under Transporter's Rate Schedule FTS-2, as
          filed with and approved by the FERC.

     (h)  If Shipper proposes or supports a change in the rate design
          methodology on which the currently effective FTS-2 rates are based, as
          set forth in Sections III.2.c and d, and III.3.b of the Phase III
          Settlement, and such proposals or changes are approved by a final
          non-appealable order, the Final Rate Cap shall be deemed waived.
          Notwithstanding the foregoing, if Transporter proposes, or any other
          party proposes and Transporter either supports or does not oppose, a
          change to any of such rate design methodologies in any Section 4 or
          Section 5 proceeding, then Shipper may take a position on that
          particular rate design methodology in that proceeding, whether or not
          consistent with the position taken by Transporter, without waiving the
          Final Rate Cap, and unless otherwise agreed by Transporter and
          Shipper, approval of such a proposed change in the rate design
          methodology by a final non-appealable order, in such Section 4 or
          Section 5 proceeding, shall not affect the

                               RATE SCHEDULE FTS-2

          continuing applicability of the Final Rate Cap. Specifically, the rate
          design methodology issues referenced above in this Section (h) are as
          follows:

          (i)  the straight fixed variable method of rate design, and of
               classifying and allocating costs,

          (ii) unless otherwise agreed to by both parties hereto, the
               system-wide postage stamp rate for FTS-2 service to the Market
               Area,

          (iii) the levelized rate methodology through March 31, 2005, and
               thereafter, the traditional cost-of-service methodology, and

          (iv) the methodology of allocating the operation and maintenance
               ("O&M") costs between Rate Schedules FTS-1 and FTS-2; provided,
               however, that without waiving its final Rate Cap under this
               Section (h) (iv), and with respect to the allocation of
               administrative and general ("A&G") expenses only, a Shipper may
               challenge, on a prospective basis only, Transporter's use of the
               Kansas-Nebraska methodology in the Section 4 rate case to be
               filed by Transporter in accordance with Article XI of the
               Settlement approved by the FERC in Docket No. RP04-12; and
               provided further, that Shipper may, without waiving its Final
               Rate Cap (and regardless of any position taken by Transporter),
               argue for any allocation methodology that allocates no more O&M
               costs to Rate Schedule FTS-2 than would otherwise be allocated by
               use of:

               a.   the Phase III Settlement methodology for allocating all O&M
                    costs except for A&G expenses, and

               b.   the Kansas-Nebraska methodology for allocating A&G expenses.

5.1  This Agreement shall become effective upon the date first written above and
     shall continue in effect for a primary term of Twenty (20) years commencing
     with the Service Commencement Date.

5.2  In the event the capacity being contracted for was acquired pursuant to
     Section 18.E. of Transporter's Tariff, then this Agreement shall terminate
     on the date set forth in Section 5.1 above. Otherwise, in accordance with
     the provisions of Section 20 of the General Terms and Conditions of
     Transporter's Tariff, Shipper has elected [Right of First Refusal or
     Roll-over Option] and upon the expiration of the primary term and any
     extension or roll-over, termination will be governed by the provisions of
     Section 20 of the General Terms and Conditions of Transporter's Tariff.

5.3  [deleted - not applicable]

5.4  Shipper may buy out of a Service Agreement for all or a portion of its
     transportation capacity ("MDTQ") thereunder, at any time, by paying
     Transporter the net present value of Shipper's remaining reservation charge
     obligations for such capacity, discounted at a reasonable rate to be
     mutually agreed upon by the parties at the time of such buy-out.

5.5  Notwithstanding any other provision in this Agreement, after the Service
     Commencement Date, in the event that: (1) Shipper is capable of using gas;
     and (2) Transporter is unable to deliver Shipper's designated volumes at
     the specified Delivery Point(s) and at the pressures provided for in this
     Agreement for a period of two consecutive days ("Service Cessation"),
     Shipper shall have the right to reduce the MDTQ by the volumes not
     delivered, without costs or penalty, by providing written notice to
     Transporter within forty-five (45) days of such occurrence; provided,
     however, that if a Service Cessation occurs more than five (5) times in any
     calendar year, Shipper shall have the right to terminate this Agreement by
     providing written notice to Transporter within forty-five (45) days of such
     occurrence; provided further, however, that if Transporter's failure to
     deliver is due to events of Transporter's force majeure as defined in Rate
     Schedule FTS-2, Shipper shall have the right to terminate or to reduce the
     MDTQ only in the event such force majeure continues for more than one
     hundred eighty-five (185) consecutive days of any three hundred sixty-five
     (365) day period.

     Point of Receipt, with respect to the Hines Unit #4 Capacity and System
     Supply Capacity, for all gas delivered by Shipper to Transporter under this
     Agreement shall be at the Point(s) of Receipt on the pipeline system of
     Transporter or any Transporting Pipeline as set forth in Exhibit A attached
     hereto, as the same may be amended from time to time. In accordance with
     the provisions of Section 8.A. of Rate Schedule FTS-2 and Section 21.C. of
     the General Terms and Conditions of Transporter's Tariff, Shipper may
     request changes in its Primary Point(s) of Receipt. Transporter may make

     applicable General Terms and Conditions of its Tariff.

6.2  The Primary Point(s) of Delivery and maximum daily quantity for each point
     for all gas made available for delivery by Transporter to Shipper, or for

     #4 Capacity and System Supply Capacity shall be at the Point(s) of Delivery
     as set forth in Exhibit B hereto, as same may be amended from time to time,

     provisions of Section 9.A. of Rate Schedule FTS-2 and Section 21.C. of the
     General Terms and Conditions of Transporter's Tariff, Shipper may request
     changes in its Primary Point(s) of Delivery provided that such new
     requested Primary Delivery Points must be located in Transporter's Market
     Area. Transporter may make such changes in accordance with the terms of
     Rate Schedule FTS-2 and the applicable General Terms and Conditions of its
     Tariff. Transporter is not obligated to accept changes where the new
     Primary Delivery point is also a delivery point under a Rate Schedule SFTS

     Re: Proposal for Transportation Services by and between Florida Power
         Corporation, d/b/a Progress Energy Florida, Inc., and Florida Gas
         Transmission Company (regarding expansion of Florida Gas Transmission
         Company's system to provide incremental capacity for receipts of LNG
         from Southern Natural Gas Company)

Dear Ms. Murphy:

     Florida Power Corporation d/b/a Progress Energy Florida, Inc. ("Progress"
or "Shipper") and Florida Gas Transmission Company ("FGT") hereby enter into
this letter agreement ("Letter Agreement") regarding the expansion of the FGT
system to provide incremental capacity to Progress as part of a project to bring
liquefied natural gas ("LNG") to the State of Florida via Southern Natural Gas
Company's ("SNG") proposed Cypress Pipeline project. In consideration of the
premises and mutual covenants set forth herein, FGT and Shipper agree as
follows:

     1. Upon satisfaction of the conditions precedent set forth below, the
parties will enter an FTS-2 service agreement (with terms and conditions
substantially similar to those contained in the draft attached hereto as
Attachment A), providing for firm natural gas transportation service to be
provided by FGT for Shipper:

          a.   Completion of an open season for an FGT 2007-2008 expansion of
               its system, and

          b.   A determination by FGT, after the close of such open season, but
               in any case, by February 1, 2005, that the capacity desired by
               Shipper can be economically provided, in FGT's sole opinion,
               under the terms set forth in the attached draft agreements.

     2. In the event that the conditions precedent set forth in "1" above are
met, the parties shall execute the Service Agreement attached hereto as
Attachment A, and shall also

execute an amendment to certain existing service agreements between the parties,
in order to increase the minimum delivery pressure at the Progress-Hines
Delivery Point from 500 psig to 575 psig, effective upon the in-service date of
the Incremental Facilities (as defined in Section 1.3 of the FTS-2 Agreement
attached as Attachment A hereto), such agreements being: (a) the FTS-1
Transportation Service Agreement dated April 1, 1998, (b) the FTS-2
Transportation Service Agreement dated April 1, 1998, (c) the FTS-2
Transportation Service Agreement dated October 7, 1998, and (d) the FTS-2
Transportation Service Agreement dated December 2, 2004.

     3. This Letter Agreement shall become effective on the date of its
execution by both parties and shall remain in effect until the earlier of: (a)
the date of execution of FTS-2 Agreement (in form substantially similar to the
attached draft agreement), (b) the date that either party notifies the other
party that such condition(s) precedent will not be met, or (c) February 1, 2005.
In the event that the parties do not execute the agreements attached as
Attachment A by February 1, 2005, all obligations of the parties shall terminate
and this Letter Agreement, as well as any agreements of the parties (oral or
otherwise) with respect to such Letter Agreement, shall become null and void and
of no further force and effect.

     If this Letter Agreement meets with your approval, please sign below and
return one of the two originals to us.

1.4  The term "In-Service Date" shall mean the date the Incremental Facilities,
     as defined in 1.3, shall go into service provided that all conditions set
     forth in Article XI hereof have first been satisfied, which In-Service Date
     shall be no later than May 1, 2009.

                                   ARTICLE II
                                    QUANTITY

2.1  The Maximum Daily Transportation Quantity ("MDTQ") with respect to each
     component of the Hines Unit #4 Capacity and System Supply Capacity provided
     for herein is set forth on a seasonal basis, and by Division if applicable,
     on Exhibit B attached hereto as the same may be amended from time to time.
     The respective applicable MDTQs (as of May 1, 2009, the MDTQs of [*]
     MMBtu/d for the Hines Unit #4 Capacity, and [*] MMBtu/d for System Supply

                 PAYMENT AND RIGHTS IN THE EVENT OF NON-PAYMENT

3.1  Upon the commencement of service hereunder (following the In-Service Date),
     Shipper shall pay Transporter, for all service rendered hereunder, the
     rates established in Article IV herein.

3.2  Termination for Non-Payment. In the event Shipper fails to pay for the
     service provided under this Agreement, pursuant to the conditions set forth
     in Section 15 of the General Terms and Conditions of Transporter's FERC Gas

     Agreement pursuant to the conditions set forth in said Section 15.

                                   ARTICLE IV
                    RATES AND TERMS AND CONDITIONS OF SERVICE

4.1  This Agreement in all respects shall be and remain subject to the
     provisions of Rate Schedule FTS-2 and of the applicable provisions of the
     General Terms and Conditions of Transporter on file with the FERC (as the
     same may hereafter be legally amended or superseded), all of which are made
     a part hereof by this reference.

4.2  Transporter shall have the unilateral right to file with the appropriate
     regulatory authority and seek to make changes in (a) the rates and charges
     applicable to its Rate Schedule FTS-2, (b) Rate Schedule FTS-2 including
     the Form of Service Agreement and the existing Service Agreement pursuant
     to which this service is rendered; provided however, that the firm
     character of service shall not be subject to change hereunder by means of a
     Section 4 Filing by Transporter, and/or (c) any provisions of the General
     Terms and Conditions of Transporter's Tariff applicable to Rate Schedule
     FTS-2. Transporter agrees that Shipper may protest or contest the
     aforementioned filings, or seek authorization from duly constituted
     regulatory authorities for such adjustment of Transporter's existing FERC
     Gas Tariff as may be found necessary in order to assure that the provisions
     in (a), (b) or (c) above are just and reasonable.

4.3  Notwithstanding Section 4.1 above, as of the In-Service Date and during the
     primary term of this Agreement, Shipper shall pay Transporter, for all
     services rendered hereunder, the

                      FIRM TRANSPORTATION SERVICE AGREEMENT
                               RATE SCHEDULE FTS-2

     lower of: (I) the rates established under Transporter's Rate Schedule FTS-2
     (inclusive of all applicable surcharges), as filed with and approved by the
     FERC and as said Rate Schedule may hereafter be legally amended or
     superseded, or (2) the Final Rate Cap as determined below:

     (a)  The Base Rate Cap shall be as follows: $[*]/MMBtu/d.

     (b)  The Base Rate Cap assumes the levelized rate methodology through March
          31, 2005, and thereafter, the traditional cost of service methodology.
          For purposes of this section with respect to this Agreement, a
          "levelized rate" shall mean a rate designed by adjusting the annual
          depreciation expense such that it results in a levelized cost of
          service.

     (c)  The Base Rate Cap is stated in nominal dollars, and shall exclude all
          applicable surcharges and fuel.

     (d)  Beginning on January 1, 2005, and annually thereafter ("Escalation
          Date"), the Base Rate Cap then in effect shall be escalated in
          accordance with the following formula; provided that in no event shall
          the Base Rate Cap, as it may be escalated pursuant to this subsection
          (d), exceed $[*] per MMBtu. On each Escalation Date, the Base Rate Cap
          to be effective for the subsequent twelve (12) month period shall be
          the sum of: (i) [*] multiplied by the Prior Base Rate Cap, which is
          defined herein as the Base Rate Cap that was effective for the twelve
          (12) month period immediately preceding the Escalation Date, and (ii)
          [*] multiplied by the Prior Base Rate Cap, [*].

     (e)  (i) For any billing month, the Final Rate Cap (stated on a per unit
          basis) shall be determined by adding the Base Rate Cap and an amount
          equal to the aggregate of the applicable surcharges (as defined in
          section (e)(ii) below).

          (ii) The type of surcharges contemplated under Rate Schedule FTS-2 to
               be included in the calculation of the Final Rate Cap are
               applicable surcharges, such as ACA, fuel, and Capital surcharges;
               provided, however, Transporter shall not collect under this
               Agreement any surcharge associated with GRI, Gas Supply
               Realignment ("GSR"), the recovery of take-or-pay costs or gas

               purchase reformation costs, FERC Account No.191 costs
               ("restructuring costs"), or any similar surcharge associated with
               the restructuring of Transporter's merchant service under orders
               in FERC Docket No. RS92-16-000 or similar proceedings, any
               separately stated surcharge related to the recovery of
               restructuring costs of any upstream provider of transportation or
               sales services to Transporter, or, to the extent such charges may
               be discountable, any industry-wide research and development
               surcharges such as those currently proposed in FERC Docket No.
               RP04-378.

     (f)  If, at any time after the In-Service Date and during the primary term
          of this Agreement, the effective rate that Transporter is authorized
          by the FERC to charge Shipper, including surcharges, exceeds the Final
          Rate Cap, then Transporter shall discount such authorized FERC rate
          down to the Final Rate Cap in accordance with the order of discounting
          provided for in Transporter's FERC Gas Tariff.

     (g)  Unless otherwise mutually agreed by the Parties, after the expiration
          of the primary term of this Agreement, Shipper shall pay Transporter
          the rates established under Transporter's Rate Schedule FTS-2, as
          filed with and approved by the FERC.

     (h)  If Shipper proposes or supports a change in the rate design
          methodology on which the currently effective FTS-2 rates are based, as
          set forth in Sections III.2.c and d, and III.3.b of the Phase III
          Settlement, and such proposals or changes are approved by a final
          non-appealable order, the Final Rate Cap shall be deemed waived.
          Notwithstanding the foregoing, if Transporter proposes, or any other
          party proposes and Transporter either supports or does not oppose, a
          change to any of such rate design methodologies in any Section 4 or
          Section 5 proceeding, then Shipper may take a position on that
          particular rate design methodology in that proceeding, whether or not
          consistent with the position taken by Transporter, without waiving the
          Final Rate Cap, and unless otherwise agreed by Transporter and
          Shipper, approval of such a proposed change in the rate design
          methodology by a final non-appealable order, in such Section 4 or
          Section 5 proceeding, shall not affect the continuing applicability of
          the Final Rate Cap. Specifically, the rate design methodology issues
          referenced above in this Section (h) are as follows:

                               RATE SCHEDULE FTS-2

          (i)  the straight fixed variable method of rate design, and of
               classifying and allocating costs,

          (ii) unless otherwise agreed to by both parties hereto, the
               system-wide postage stamp rate for FTS-2 service to the Market
               Area,

          (iii) the levelized rate methodology through March 31, 2005, and
               thereafter, the traditional cost-of-service methodology, and

          (iv) the methodology of allocating the operation and maintenance
               ("O&M") costs between Rate Schedules FTS-1 and FTS-2; provided,
               however, that without waiving its final Rate Cap under this
               Section (h) (iv), and with respect to the allocation of
               administrative and general ("A&G") expenses only, a Shipper may
               challenge, on a prospective basis only, Transporter's use of the
               Kansas-Nebraska methodology in the Section 4 rate case to be
               filed by Transporter in accordance with Article XI of the
               Settlement approved by the FERC in Docket No. RP04-12; and
               provided further, that Shipper may, without waiving its Final
               Rate Cap (and regardless of any position taken by Transporter),
               argue for any allocation methodology that allocates no more O&M
               costs to Rate Schedule FTS-2 than would otherwise be allocated by
               use of:

               a.   the Phase III Settlement methodology for allocating all O&M
                    costs except for A&G expenses, and

               b.   the Kansas-Nebraska methodology for allocating A&G expenses.

5.2  In the event the capacity being contracted for was acquired pursuant to
     Section 18.E. of Transporter's Tariff, then this Agreement shall terminate
     on the date set forth in Section 5.1 above. Otherwise, in accordance with
     the provisions of Section 20 of the General Terms and Conditions of
     Transporter's Tariff, Shipper has elected [Right of First Refusal or
     Roll-over Option] and upon the expiration of the primary term and any
     extension or roll-over, termination will be governed by the provisions of
     Section 20 of the General Terms and Conditions of Transporter's Tariff.

5.3  [deleted - not applicable]

5.4  Shipper may buy out of a Service Agreement for all or a portion of its
     transportation capacity ("MDTQ") thereunder, at any time, by paying
     Transporter the net present value of Shipper's remaining reservation charge
     obligations for such capacity, discounted at a reasonable rate to be
     mutually agreed upon by the parties at the time of such buy-out.

5.5  Notwithstanding any other provision in this Agreement, after the In-Service
     Date , in the event that: (1) Shipper is capable of using gas and (2)
     Transporter is unable to deliver Shipper's designated volumes at the
     specified Delivery Point(s) and at the pressures provided for in this
     Agreement for a period of two consecutive days ("Service Cessation"),
     Shipper shall have the right to reduce the MDTQ by the volumes not
     delivered, without costs or penalty, by providing written notice to
     Transporter within forty-five (45) days of such occurrence; provided,
     however, that if a Service Cessation occurs more than five (5) times in any
     calendar year, Shipper shall have the right to terminate this Agreement by
     providing written notice to Transporter within forty-five (45) days of such
     occurrence; provided further, however, that if Transporter's failure to
     deliver is due to events of Transporter's force majeure as defined in Rate
     Schedule FTS-2, Shipper shall have the right to terminate or to reduce the
     MDTQ only in the event such force majeure continues for more than one
     hundred eighty-five (185) consecutive days of any three hundred sixty-five
     (365) day period.

Re: Discount of Rate Under the Firm Transportation (FTS-2) Service Agreement
    dated December 2, 2004 ("Agreement") Between Florida Gas Transmission
    Company ("FGT" or "Transporter") and Florida Power Corporation d/b/a
    Progress Energy Florida, Inc. ("Progress" or "Shipper") (collectively the
    "Parties" or singularly "Party").

Dear Ms. Murphy:

     Shipper has requested a competitive discount. Based upon current market
conditions, Transporter has agreed to charge and Shipper has agreed to pay a
discounted rate for transportation of quantities of gas under the Agreement. The
terms and conditions of the discount agreed upon are expressed in this Discount
Agreement ("Discount Agreement").

     This Discount Agreement shall be effective from October 1, 2007 through
April 30, 2027 (and supercedes and cancels the Discount Agreement dated October
7, 2004); provided, however, in the event that the referenced Agreement is
terminated, this Discount Agreement shall immediately terminate.

     The Maximum Daily Transportation Quantity (MDTQ) shall be as follows, and,
unless expressly agreed otherwise, FGT's maximum rates shall apply to volumes
exceeding such amounts:

October 2008 - April 2009                          [*]

For the months of October through April
for the years 2009 through 2027                    [*]

The primary receipt and delivery points for the term(s) of this discount shall
be as follows:

Effective for the periods stated below, Shipper shall pay the following
Discounted Reservation Charges per MMBtu ("Discounted Demand Charge"), plus all
applicable surcharges; provided, however, FGT shall discount the any research
and development ("R&D") surcharges (whether demand or volumetric) to $0.00 per
MMBtu for transportation of quantities under the Agreement:

For the months of October
through April, for the
years 2009 through 2027          [*]              [*]
</TABLE>

In addition to the above rate(s), Shipper shall also pay any applicable fuel use
and unaccounted for charges, as well as any fuel surcharge.

Except for the posting of information by FGT pursuant to 18 C.F.R. Parts 161,
284, and 358 and any other applicable regulations of the Federal Energy
Regulatory Commission ("FERC"), each Party agrees that it will maintain this
discount, all of its contents and subsequent discount documentation and
communications in strict confidence and that it will not cause or permit
disclosure thereof to any third party without the express written consent of the
other Party except to the extent necessary to comply with valid laws,
regulations, or orders of any court or agency having jurisdiction. However, in
the event either Party becomes aware of a judicial or administrative proceeding
or request that has resulted or that may result in such disclosure, it shall
notify the other Party immediately and will also take all actions necessary to
maintain the confidentiality of all discount communications and documents.
Notwithstanding anything to the contrary in this paragraph, Shipper shall have
the right to provide a copy of this Discount Agreement to the Florida Public
Service Commission and any other entity that is a party to the relevant docket
that has executed a confidentiality agreement to retain such information
confidential, without prior notice to or consent of Transporter, in connection
with

Shipper's attempts to obtain the Florida Public Service Commission's
approval of this Discount Agreement and the Agreements.

As stated above, any R&D surcharge shall be discounted to $0.00; provided,
however that such discount shall immediately terminate in the event FGT is
required to absorb any costs associated with discounting any R&D surcharge or
FGT is prohibited by law from granting such discount.

Shipper shall affirmatively support the continuation of FERC's discount rate
adjustment policy (providing for recognition of volumes flowing at less than
maximum rates in rate proceedings). In the event that Shipper takes a contrary
position in any future rate, rulemaking, or other proceeding before the FERC (or
other governmental body having jurisdiction in the premises), this Discount
Agreement shall immediately terminate.

In the event the maximum and minimum rates applicable to Rate Schedule FTS-2 are
changed pursuant to an Order issued by the FERC, such that the transportation
rates provided for herein are above FGT's maximum rates or below FGT's minimum
rates, this Agreement shall terminate immediately prior to the effectiveness of
such revised rates, and FGT and Shipper shall negotiate to arrive at new rates
applicable to the transportation service. It is the intent of FGT and Shipper
that such renegotiated discounted rates will leave both FGT and Shipper in
substantially the same economic position as the transportation rates provided
for herein.

THIS AGREEMENT SHALL BE GOVERNED BY AND INTERPRETED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF TEXAS, WITHOUT REFERENCE TO ANY CONFLICT OF LAWS DOCTRINE WHICH
WOULD APPLY THE LAWS OF ANOTHER JURISDICTION. ANY SUIT BROUGHT WITH RESPECT TO
OR RELATING TO THIS LETTER AGREEMENT SHALL BE BROUGHT IN THE COURTS OF HARRIS
COUNTY, TEXAS OR THE SOUTHERN DISTRICT OF TEXAS, HOUSTON DIVISION.

     The Parties have caused this Discount Agreement to be executed by their
respective duly authorized officers as of the date first mentioned above.

Re:      Letter Agreement Amending the Firm Transportation Service Agreements by
         and between Florida Power Corporation, d/b/a Progress Energy Florida,
         Inc., and Florida Gas Transmission Company: (1) FTS-1 dated April 1,
         1998, (2) FTS-2 dated April 1, 1998, (3) FTS-2 dated October 7, 1998,
         and (4) FTS-2 dated December 2, 2004

Dear Ms. Murphy:

         Florida Power Corporation d/b/a Progress Energy Florida, Inc.
("Progress" or "Shipper") and Florida Gas Transmission Company ("FGT") hereby
enter into this letter agreement ("Letter Agreement"), regarding the amendment
to the referenced existing firm service agreements. In consideration of the
premises and mutual covenants set forth herein, FGT and Shipper agree as
follows:

         1. Immediately upon the in-service date of FGT's proposed Phase VII
Expansion, FGT and Shipper agree to execute a revised Exhibit B to each of the
referenced firm service agreements, to reflect that the minimum delivery
pressure at Shipper's Progress-Hines Delivery Point shall be 575 psig, effective
upon the in-service date of any additional facilities necessary to be
constructed by FGT and by Southern Natural Gas Company in connection with the
seasonal incremental service to be provided under the FTS-2 Firm Service
Agreement dated January 31, 2005.

         2. The parties hereby reaffirm the FTS-2 Firm Transportation Service
Agreement dated October 7, 1998. Although, by letter agreement dated June 14,
1999, the parties agreed to execute a new replacement service agreement
(covering service by means of FGT's Phase IV Expansion), the parties acknowledge
that, on October 11, 2000, they amended Exhibits A and B to such agreement
(effective on October 7, 1998), in place of entering into a replacement service
agreement.

         3. This Letter Agreement shall become effective on the date of its
execution by both parties. In the event that the parties' FTS-2 Firm Service
Transportation Agreement dated January 31, 2005 (for service by means of FGT's
proposed Phase VII Expansion) is terminated or cancelled without service
commencing, Section 1 of this Letter Agreement will no longer be of any force
and effect, and the obligation of the parties to amend the referenced agreements
shall terminate and become null and void and of no further force and effect.

         If this Letter Agreement meets with your approval, please sign below
and return one of the two originals to us.



                                             Yours truly,
