Consummation of this Agreement by Buyer with knowledge of any breach of such representations and warranties by Seller will not constitute a waiver or release by Buyer of any claims due to such breach; provided, however, Buyer shall provide Seller with written notice of any such breach immediately upon Buyer having knowledge thereof and shall give Seller a reasonable opportunity to cure any such breach and to mitigate any damages to Seller arising therefrom or related thereto. Notwithstanding the foregoing, Seller shall have no liability for damages for the breach of any of the warranties and representations contained herein until any individual claim therefore exceeds the amount of $25,000. Seller’s liability for damages for the breach of any of the warranties and representations contained herein

shall be limited to actual damages (and not special or consequential damages) and shall be limited to the sum of $2,000,000.00

8. Representations and Warranties of Buyer. Buyer represents and warrants to Seller that Buyer is a limited liability company duly organized in the State of Delaware and is qualified to transact business in the State of Alabama; that Buyer has the requisite company power and authority to enter into this Agreement and the Buyer’s Closing Documents signed by it; such documents have been duly authorized by all necessary corporate action on the part of Buyer and have been duly executed and delivered; that the execution, delivery and performance by Buyer of such documents do not conflict with or result in violation of Buyer’s Articles of Organization or Membership Agreements or any judgment, order or decree of any court or arbiter to which Buyer is a party; such documents are valid and binding obligations of Buyer, and are enforceable in accordance with their terms. Buyer will indemnify Seller, its successors and assigns, against, and will hold Seller, its successors and assigns, harmless from, any expenses or damages, including reasonable attorneys’ fees, that Seller incurs because of (i) the breach of any of the above representations and warranties, whether such breach is discovered before or after closing and (ii) the ownership, operation and maintenance of the Property by Buyer, its successors and assigns, after the Closing. Consummation of this Agreement by Seller with knowledge of any breach of such warranties and representations by Buyer will not constitute a waiver or release by Seller of any claims due to such breach, provided, however, Seller shall provide Buyer with written notice of any such breach immediately upon Buyer having knowledge thereof and shall give Buyer a reasonable opportunity to cure any such breach and to mitigate any damages to Seller arising therefrom or related thereto. Each of the representations and warranties herein contained shall survive for two (2) years from the date of the Closing. Notwithstanding the foregoing, Buyer shall have no liability for damages for the breach of any of the warranties and representations contained herein until any individual claim therefore exceeds the amount of $25,000. Buyer’s liability for damages for the breach of any of the warranties and representations contained herein shall be limited to actual damages (and not special or consequential damages) and, together with Buyer’s liability under Section 12 of this Agreement, shall be limited to a total sum of $2,000,000.00.

9. Right of First Refusal and Repurchase Right.

(a) Right of First Refusal. Seller is the owner of certain real property (the “Adjacent Property”) lying adjacent to the Property. At Closing, Seller shall grant to Buyer a right of first refusal if Seller receives an offer to sell all or any part of the Adjacent Property, which offer Seller desires to accept (the “Right of First Refusal”). The Right of First Refusal shall be subject to any rights previously granted to Seller’s present lessee or any tenant or user of the Adjacent Property.

(b) Repurchase Right. At Closing, Buyer shall grant Seller the right, but not the obligation, to repurchase the Property if Buyer does not commence construction of its intended improvements within one (1) year after the Closing Date (the “Repurchase Right”).

10. Condemnation. If, prior to the Closing Date, eminent domain proceedings are commenced against all or any material part of the Property (as reasonably determined by Buyer),

Seller shall immediately give notice to Buyer of such fact and at Buyer’s option (to be exercised within thirty (30) days after Seller’s notice), this Agreement shall terminate, in which event neither party will have further obligations under this Agreement. Thereupon, the Deposit shall be retained by Seller; provided, however, if Seller manipulated the eminent domain proceedings in bad faith for the purpose of thwarting the intent of this Agreement, $50,000 of the Deposit shall be paid to Seller and the balance of the Deposit, if any, shall be paid to Buyer If Buyer shall fail to give such notice, there shall be no reduction in the Purchase Price, and Seller shall assign to Buyer at the Closing Date all of Seller’s right, title and interest in and to any award made or to be made in the condemnation proceedings which relates to the Real Property.

11. Broker’s Commission. Seller and Buyer represent and warrant to each other that they have dealt with no brokers, finders or the like in connection with this transaction, and agree to indemnify each other and to hold each other harmless against all claims, damages, costs or expenses of or for any other such fees or commissions resulting from their actions or agreements regarding the execution or performance of this Agreement, and will pay all costs of defending any action or lawsuit brought to recover any such fees or commissions incurred by the other party, including reasonable attorneys’ fees.

12. Indemnification of Seller. Buyer shall indemnify Seller, its members, managers, affiliates, successors, assigns and lessees against, and hold each harmless from, all liabilities or losses (including reasonable attorneys’ fees and other costs of defense in defending against claims) arising out of the ownership, operation or maintenance of the Property after the Closing, except with respect to matter caused, created or allowed by Seller prior to Closing. Buyer shall take no action, allow any omission or conduct any activity upon the Property before or after the Closing which interferes with the use of the Adjacent Property by Seller’s present lessee or the exercise of any of the Vulcan Use Rights. Such rights of indemnification will not arise to the extent that (a) the party seeking indemnification actually receives insurance proceeds or other cash payments directly attributable to the liability in question, (net of the cost of collection, including reasonable attorneys’ fees and other costs of defense) or (b) to the degree the claim for indemnification arises out of the negligence or intentional acts of Seller or parties acting under Seller’s control or direction. Buyer’s liability contained herein shall be as to Seller’s “losses”, the actual losses or liability actually incurred by Seller (as opposed to consequential or special losses or damages) after Seller having taken reasonable steps to mitigate its losses. Any indemnity agreement made by Buyer in favor of Seller as part of the Use Agreement shall be in addition to, and shall not be limited by, the indemnification provisions of this Section 12.

13. Assignment. Buyer may assign its rights under this Agreement without the consent of Seller provided the assignee confirms to Seller in writing at the time of such assignment that it intends to use the Property for a use materially the same as Buyer’s intended use. Any assignment to a third party that intends to use the Property for a use that is materially different than Buyer’s intended use is prohibited. Any such assignment will not relieve such assigning party of its obligations under this Agreement.

14. Survival. All of the terms of this Agreement will survive and be enforceable after the Closing except as noted herein.

15. Notices. Any notices required or permitted to be given hereunder shall be in writing and shall be effective (i) when delivered personally, (ii) when received by overnight courier service or (iii) three (3) days after being deposited in the United States Mail (sent certified or registered, return receipt requested), in each case addressed as follows (or to such other address as the parties hereto may designate in the manner set forth herein):

If, but only if, a court of competent jurisdiction determines that the remedy of specific performance is not available, then Buyer may seek its actual damages and all of Buyer’s costs and expenses of bringing the action, including reasonable attorneys’ fees and professional fees, resulting from Seller’s default; provided, however, in such event, Seller shall not be liable to Buyer for the collective amount of any actual damages and costs and expenses of bringing the action, including reasonable attorneys’ fees and professional fees, or other relief, in an amount greater than One Million Dollars ($1,000,000.00). In no event shall Seller be liable to Buyer for special, consequential or punitive damages and Buyer hereby waives any claim with respect thereto.

21. Counterparts. This Agreement may be executed in multiple counterparts which, when taken together, shall constitute a single instrument.

EXHIBIT C

Use Agreement Summary

Seller and Buyer shall enter into an Easement and Use Agreement (the “Use Agreement”). The Use Agreement will, without limitation, include the following:

(a) Non-exclusive easements running from Seller for the benefit of the Buyer and the Real Property over and across Seller’s Property for the purpose of ingress and egress to the Real Property and for the use of the roadways as currently located within Seller’s Property which are not currently leased or controlled by Seller’s present lessee;

(b) Non-exclusive rights to use the railway lines now existing on Seller’s Property;

(c) Exclusive easement rights to use certain dock areas located on Seller’s Property, together with non-exclusive rights to use wharf area adjacent to the dock areas;

(d) Non-exclusive utility easements; and

(e) Non-exclusive grant of an easement for drainage purposes over Seller’s Property.

The Use Agreement will recognize the Vulcan Use Rights and will attempt, to the greatest degree possible, to create the use rights in favor of Buyer in such a manner that such use rights do not conflict or interfere with the Vulcan Use Rights. To the extent that any of the rights proposed to be granted under the Use Agreement would interfere or conflict with the Vulcan Use Rights, such grant shall be conditioned upon Vulcan’s written consent and, in any event, Seller and Buyer intend to obtain the acknowledgment and consent of Vulcan to the Use Agreement.

The Use Agreement will provide for the delegation of responsibility for certain common area maintenance within Seller’s Property for common areas that benefit Seller, Vulcan, and Buyer and will provide for the equitable sharing of the common area maintenance costs.

The Use Agreement will create an easement over and across the Real Property consisting of a strip of land along the perimeter of the Real Property to allow for the construction and maintenance of a rail car loading area or areas, with structural improvements, serving the rail tracks located on the Seller’s Property.

The Use Agreement will provide that if the ownership of the plant facility to be constructed on the Real Property becomes separate from the ownership of the Real Property, the owner of the plant facility shall be jointly or severally liable for the performance and payment of the TVAE liabilities and obligations under the Use Agreement.

The Use Agreement will obligate the owner of the Real Property to pay to Seller a Tonnage Charge (the “Tonnage Charge”) as generally described in the Letter of Intent between Seller and Buyer dated November 7, 2007.
