  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On April&nbsp;18, 2008, we purchased certain
  natural gas futures contracts, which we refer to as the futures contracts, to
  attempt to hedge our exposure to cash flow variability related to the
  fixed-price component of a liquefied natural gas (LNG) supply contract for
  which we have submitted a fixed-price bid.&#160;
  The supply contract has not yet been awarded to us. If we are awarded
  the supply contract, performance is anticipated to begin on July&nbsp;1, 2008,
  with LNG to be sold at a fixed price for the first three years of the
  contract.&#160; The contract would have two
  one-year renewal options based on an index-plus pricing methodology.&#160; While we have not received final notification
  that we have been awarded the contract, due to the fact that the contract price
  is fixed for the initial three-year term, as well as the fact that natural gas
  prices have recently had significant increases, our derivative committee
  concluded it was advisable to purchase the futures contracts in advance of the
  anticipated contract award.</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The purchase of the futures contracts was in
  accordance with the revised natural gas hedging policy adopted by our board of
  directors in February&nbsp;2007.&#160; This
  policy is discussed in Part&nbsp;II, Item 7 (Management&#146;s Discussion and
  Analysis of Financial Condition and Results of Operation) of our annual report
  on Form&nbsp;10-K for the year ended December&nbsp;31, 2007, which discussion
  is incorporated herein by reference.</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The futures contracts enable us to purchase
  natural gas at fixed prices each month from July&nbsp;2008 through June&nbsp;2011,
  which is the expected fixed-price term of the supply contract.&#160; Until such time as we are awarded and enter
  into the supply contract, the futures contracts will not qualify for hedge
  accounting as cash flow hedges under SFAS No.&nbsp;133.&#160; As a result, we will be required to record
  directly in our statement of operations any changes in the fair market value of
  these contracts that may occur from April&nbsp;18, 2008 through the earlier to
  occur of (1)&nbsp;our entry into the fixed-price supply contract and success in
  qualifying the futures contracts for hedge accounting under SFAS No.&nbsp;133,
  or (2)&nbsp;the sale of the futures contracts.&#160;
  An increase or decrease of $1.00 in the price per MMbtu of natural gas
  would result in a gain or loss, respectively, of approximately $3.1 million in
  the fair market value of the futures contracts.</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">To purchase the futures contracts, we were
  required to make an initial margin deposit of $1,236,000.&#160; We may be required to make additional
  deposits if we incur losses related to the futures contracts.</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">If we are awarded and enter into the supply
  contract, (1)&nbsp;we will attempt to qualify the futures contracts for hedge
  accounting as cash flow hedges under SFAS No.&nbsp;133, but there can be no
  assurances we will be successful in doing so, and (2)&nbsp;we anticipate that
  we will hold the futures contracts for the duration of the contract term
  consistent with the revised natural gas hedging policy adopted by our board of
  directors in February&nbsp;2007.&#160; If we
  are not awarded or fail to enter into the supply contract, we intend to sell
  the futures contracts in an orderly fashion.</font></p>

  Item 8.01.
  Other Information.
  On April 18, 2008, we purchased certain
  natural gas futures contracts, which we refer to as the futures contracts, to
  attempt to hedge our exposure to cash flow variability related to the
  fixed-price component of a liquefied natural gas (LNG) supply contract for
  which we have submitted a fixed-price bid. 
  The supply contract has not yet been awarded to us. If we are awarded
  the supply contract, performance is anticipated to begin on July 1, 2008,
  with LNG to be sold at a fixed price for the first three years of the
  contract.  The contract would have two
  one-year renewal options based on an index-plus pricing methodology.  While we have not received final notification
  that we have been awarded the contract, due to the fact that the contract price
  is fixed for the initial three-year term, as well as the fact that natural gas
  prices have recently had significant increases, our derivative committee
  concluded it was advisable to purchase the futures contracts in advance of the
  anticipated contract award.
  The purchase of the futures contracts was in
  accordance with the revised natural gas hedging policy adopted by our board of
  directors in February 2007.  This
  policy is discussed in Part II, Item 7 (Management's Discussion and
  Analysis of Financial Condition and Results of Operation) of our annual report
  on Form 10-K for the year ended December 31, 2007, which discussion
  is incorporated herein by reference.
  The futures contracts enable us to purchase
  natural gas at fixed prices each month from July 2008 through June 2011,
  which is the expected fixed-price term of the supply contract.  Until such time as we are awarded and enter
  into the supply contract, the futures contracts will not qualify for hedge
  accounting as cash flow hedges under SFAS No. 133.  As a result, we will be required to record
  directly in our statement of operations any changes in the fair market value of
  these contracts that may occur from April 18, 2008 through the earlier to
  occur of (1) our entry into the fixed-price supply contract and success in
  qualifying the futures contracts for hedge accounting under SFAS No. 133,
  or (2) the sale of the futures contracts. 
  An increase or decrease of $1.00 in the price per MMbtu of natural gas
  would result in a gain or loss, respectively, of approximately $3.1 million in
  the fair market value of the futures contracts.
  To purchase the futures contracts, we were
  required to make an initial margin deposit of $1,236,000.  We may be required to make additional
  deposits if we incur losses related to the futures contracts.
  If we are awarded and enter into the supply
  contract, (1) we will attempt to qualify the futures contracts for hedge
  accounting as cash flow hedges under SFAS No. 133, but there can be no
  assurances we will be successful in doing so, and (2) we anticipate that
  we will hold the futures contracts for the duration of the contract term
  consistent with the revised natural gas hedging policy adopted by our board of
  directors in February 2007.  If we
  are not awarded or fail to enter into the supply contract, we intend to sell
  the futures contracts in an orderly fashion.
  We purchased the futures contracts from
  Sempra Energy Trading Corp. pursuant to the terms of the ISDA Master Agreement
  dated March 23, 2006 between us and Sempra, including the ISDA Credit
  Support Index to the Schedule to the ISDA Master Agreement dated March 23,
  2006, which documents are attached as Exhibits 10.13 and 10.14,
  respectively, to the Form S-1 Registration Statement (File No. 333-137124)
  we filed with the SEC on September 6, 2006.  These documents are incorporated herein by
  reference.
