The principal payments on the Loan shall be due semi-annually on the 30^th day of June and the 31^st day of December of each year in installments sufficient to repay the total loan within a period of time determined by the weighted average life of the equipment being purchased or twenty (20) years, whichever is less, commencing on the earlier of December 31, 2012, or the next scheduled payment date that is at least six months after the Start of Commercial Production (as defined in the MOU) (“weighted averaged life” shall mean the result of finding the sum of the products produced by multiplying the cost of each piece of Loan-financed equipment by its useful life and then dividing such sum by the total cost of all Loan-financed equipment) . The entire amount of the outstanding principal balance and all other applicable costs, charges or expenses is due and payable no later than the date which is twenty (20) years from the date of the initial repayment of the loan proceeds hereunder by the Borrower. Provided the first payment is prior to completion of Borrower’s annual financial statement audit, Borrower will estimate the first payment and will perform a final payment calculation after completion of the audit. Borrower will adjust the second payment to reflect any adjustment resulting from the post-audit payment calculation. Equipment lives will be determined by applying the capitalization and depreciation policy it uses for preparation of its audited financial statements. Prior to the June payment each year, the payment amount will be recalculated based on the principal amount due and owing at that time. All payments shall be payable in coin or currency of the United States of America which, at the time of payment is legal tender for the payment of the Loan and shall be made by the Borrower to the Lender by check delivered and received on payment date or by bank wire or bank transfer as Lender may specify or approve.

     Section 4.3. Obligation to Make Payments Absolute. It is understood and agreed that all payments by the Borrower under this Agreement and the Note shall be absolute and unconditional and shall not be subject to any defense (other than payment) or any right of set-off, counterclaim or recoupment.

     Section 4.4. Maintenance of Project. The Borrower will use commercially reasonable efforts to maintain, preserve and keep the Project or cause the Project to be maintained, preserved and kept, in good repair, working order and condition (subject to ordinary wear and tear) and will from time to time make or cause to be made all necessary and proper repairs, replacements and renewals.

     Section 4.5. Payment of Taxes and Assessments; Compliance with Law; No Further Liens. The Borrower will: (a) pay, or make provision for payment of, all material lawful taxes and assessments, including income, profits, property or excise taxes, if any, or other municipal or governmental charges, levied or assessed by the Federal, state or any municipal government with respect to or upon the Project or any part thereof or upon any payments hereunder when the same shall become due, other than taxes and assessments that are being contested in good faith; and (b) duly observe and comply with all valid requirements of any governmental authority necessary for the operation of the Facility.

     Section 4.6. Operation of Project. The Borrower agrees that so long as the Loan is outstanding, except (a) during periods (consisting of no more than thirty (30) consecutive calendar days nor occurring no more often than once in any thirty-six (36) month period) during which Borrower’s normal manufacturing operations at the Facility are halted because of reasons beyond

Borrower’s reasonable control, or (b) during periods after the occurrence of damage or loss to the Facility in excess of $250,000 during which Borrower has initiated and is diligently pursuing efforts to rebuild and restore the Facility, Borrower will maintain or cause to be maintained the operations of the Project, unless the Project is disposed of pursuant to Section 6.1 hereof.

     Section 4.7. Payment of Expenses. The Borrower will pay, or cause to be paid, in addition to the payments provided for in Sections 4.2 and 4.3 hereof, all of the expenses of operation of the Project, including, without limitation, the cost of all necessary and proper repairs, replacements and renewals and any and all taxes and assessments payable pursuant to Section 4.5 hereof. The Borrower further agrees to pay reasonable fees, expenses and charges incurred by Lender in making the Loan, including but not limited to, the reasonable fees and out-of-pocket expenses of counsel employed by the Mississippi Development Authority, but in all events, such payments by Borrower shall be limited to Twenty-Five Thousand Dollars ($25,000.00).

     Section 4.8. Payments Continue Upon Destruction of Project. It is understood and agreed that the payments under Section 4.2 hereof and on the Note and other charges payable hereunder shall continue to be payable at the time and in the amounts herein specified (except in connection with a prepayment permitted to be made under Section 8.1 hereof), whether or not the Project, or any portion thereof, shall have been destroyed, wholly or partially, by fire or other casualty, and that there shall be no abatement or diminution of any such payments and other charges by reason thereof.

     Section 4.9. Release and Indemnification of the Lender. The Borrower hereby releases the Lender from, and agrees that the Lender and its respective officers, directors, members, employees, attorneys, and agents shall not be liable for, and agrees to defend, indemnify and hold the Lender and its respective officers, directors, members, employees, attorneys, and agents harmless against:

     (a) any or all liability or loss, cost or expense, including reasonable attorneys’ fees, resulting from or arising out of any loss or damage to property or any injury to or death of any person occurring on or about the Project Site or resulting from any defect in the fixtures, machinery, equipment or other property located on the Project Site or arising out of, pertaining to, or having any connection with the Project or the financing thereof (whether or not arising out of acts, omissions or negligence of the Borrower);

     (b) any and all claims, damages, judgments, penalties, costs, and expenses (including reasonable attorneys’ fees and court costs now or hereafter arising from the aforesaid enforcement of this paragraph) arising directly or indirectly from (i) the activities of the Borrower or any third parties with whom Borrower has a contractual relationship, or (ii) the violation by the Borrower of any environmental protection, health, or safety law in a material respect, whether any such claims are asserted by any governmental authority or any other Person which indemnity shall survive the termination of this Agreement.

     Notwithstanding the foregoing, the release and indemnity provided for in this Section 4.9 shall not be effective to relieve the Lender or its respective officers, directors, members, employees, attorneys and agents from damages that result from negligence or intentional misconduct on the part

of the Lender or from Lender’s failure to perform any obligation under (including Lender’s obligation to fund Loans under this Agreement) or Lender’s breach of this Agreement. This release and indemnification covenant shall survive the termination of this Agreement with respect to liability arising out of any event or act occurring prior to such termination.

     Section 4.10. Insurance. Throughout the term of this Agreement, the Borrower shall keep, or cause to be so kept, any buildings and contents of those buildings at the Project Site continuously insured against such risks as are customarily insured against by businesses of like size and type (other than business interruption insurance), paying or cause to be paid as the same become due all premiums in respect thereto, including but not necessarily limited to:

     (a) Casualty insurance against loss and/or damage to any and all buildings and their contents, including the equipment that is the subject of the Loan, at the Project Site under a policy or policies covering such risks as are ordinarily insured against by similar businesses, including without limiting the generality of the foregoing, fire, lightning, windstorm, hail, explosion, and uniform standard extended coverage. Such insurance shall be for not less than the full insurable value of the buildings and their contents, including the equipment that is the subject of the Loan.

     (b) Comprehensive general public liability insurance protecting the Borrower as a named insured and the Lender as additional insured against liability for death and injuries to persons and damage to property, occurring on, in or about the Project Site.

     (c) Workers’ compensation insurance respecting all employees employed at the Project Site in such amount as is customarily carried by like organizations engaged in like activities of comparable size and liability exposure.

The insurance required may be contained in blanket policies now or hereafter maintained or caused to be maintained or approved by the Borrower.

     Certificate or certificates of insurance showing that such insurance is in force and effect shall be deposited with the Lender no later than the date on which Borrower shall take possession of any property acquired with proceeds of the Loan. Prior to expiration of any such policy, the Borrower shall furnish the Lender with evidence satisfactory to the Lender that the policy has been renewed or replaced or is no longer required by this Agreement.

     Section 4.11. Application of Insurance Proceeds.

     (a) Immediately after the occurrence of any damage or loss to the Project Site in excess of Two Hundred Fifty Thousand Dollars ($250,000.00) the Borrower shall notify the Lender as to the nature and extent of such damage or loss. If the Borrower determines that rebuilding, repairing or restoring the Project Site is practicable and desirable, the Borrower shall forthwith proceed with such rebuilding, repairing or restoring the Project Site to its former condition or to a condition that Borrower deems useful for the Project, and shall notify the Lender, upon the completion thereof. In

the event the Borrower elects to rebuild, repair or restore the Project Site, and the net proceeds of insurance, if any, will be insufficient to pay in full the costs of rebuilding, repairing or restoring the Project Site under this Section, the Borrower will nonetheless perform such rebuilding, repairing or restoration.

     (b) If the Borrower chooses not to rebuild, repair or restore the Project Site, the Borrower shall pay or cause to be paid to the Lender the proceeds of such insurance relating to the Project, if any, to be applied to the repayment of the Loan.

     (c) Any provisions of this Agreement to the contrary notwithstanding, the Borrower shall be entitled to receive, keep and retain that portion of insurance proceeds received for damages to its own property other than, if an Event of Default has occurred and is continuing, the land, buildings and equipment that is financed by the Loan. The Lender shall cooperate fully with the Borrower in the handling and the conduct of any prospective or pending insurance claims.

DEED OF TRUST, FIXTURE FILING
AND ASSIGNMENT OF LEASES AND RENTS

     THIS DEED OF TRUST, FIXTURE FILING AND ASSIGNMENT OF LEASES AND RENTS (“Deed of Trust”) is made and entered into as of the day of         , 2011, by and among KiOR Columbus, LLC, a Delaware limited liability company, hereinafter “Grantor”; Waverly Harkins, Special Assistant Attorney General, Mississippi Development Authority, Post Office Box 849, Jackson, Mississippi 39205, hereinafter “Trustee”; and Mississippi Development Authority, whose address is 501 North West Street, Jackson, Mississippi 39201, hereinafter “Beneficiary.”

     Grantor is indebted to Beneficiary in the original principal amount of Seventy-Five Million Dollars ($75,000,000.00) and such additional fees, costs and expenses as are set forth herein (the “Loan”), and has agreed to pay the same, without interest thereon, according to the terms of the Note (as defined in that certain Loan Agreement entered into by and between Grantor and Beneficiary of even date herewith (the “Loan Agreement”)) made by Grantor to the order of Beneficiary and the Loan Agreement, with final payment being due on or before 2031; and

     Grantor is executing this Deed of Trust to secure the Loan and all indebtedness and obligations now or hereafter owed to Beneficiary by the Grantor incurred pursuant to this Deed of Trust, the Note, the Loan Agreement or the Security Agreement (as defined in the Loan Agreement) and all other documents and instruments now or hereafter evidencing, describing, or securing the Loan or obligations contemplated hereby or delivered in connection herewith, as they may be modified, amended, extended, renewed or substituted from time to time, including the unpaid principal amount of the Loan, and all other obligations and liabilities of the Grantor to Beneficiary, whether direct or indirect, absolute or contingent, due or to become due, or now existing or hereafter incurred, that may arise under, or out of or in connection with the Loan, the Note, the Security Agreement, this Deed of Trust, or any other Transaction Document (as defined in the Loan Agreement) (collectively, the “Secured Obligations”);

     NOW THEREFORE, in consideration of the existing and future Secured Obligations and other good and valuable consideration, Grantor hereby conveys and warrants unto Trustee, the property described in Exhibit “A” attached hereto and made a part hereof, subject and subordinate only to those matters more particularly set forth in Exhibit “B” attached hereto and made a part hereof; together with any and all specific improvements and goods acquired by Grantor in whole or in part with proceeds from the Loan, that are or may become fixtures now or hereafter located thereon, or on any part or parcel thereof, and all additions, substitutions and replacements thereof; and together with all rights, privileges, easements, rights of way, appurtenances, streets, and roadways now or hereafter pertaining to the hereinabove described property (all of which shall be collectively referred to herein as the “Property”). Any and all improvements and goods located thereon, or on any parcel thereof, which are not acquired in whole or in part with proceeds from the Loan are specifically excluded from the definition of “Property.”

     This conveyance is in trust to secure prompt payment and performance of the Secured Obligations. If Grantor shall pay and perform the Secured Obligations, then this conveyance shall be void and of no effect.

     Grantor and Beneficiary hereby agree as follows:

     Taxes; Insurance. Grantor shall cause to be paid when due any taxes and assessments, general or special, and other obligations which may be levied or assessed upon the Property or which, if not paid, may be asserted as a lien on the Property and all taxes on this Deed of Trust or Beneficiary, hereinafter enacted arising out of this Deed of Trust or the indebtedness secured hereby.

     Grantor shall cause to be maintained insurance at all times in accordance with the applicable provisions of the Loan Agreement. All property damage and casualty insurance (or an endorsement thereto) shall name the Beneficiary as an additional loss payee/mortgagee and all liability insurance (or an endorsement thereto) shall name the Beneficiary as an additional insured. The proceeds of any property or casualty insurance in respect of any casualty loss to any of the Property shall be paid, held and applied in accordance with the applicable provisions of the Loan Agreement. Grantor shall furnish the Beneficiary upon its request with certificates of insurance and policies evidencing compliance with the foregoing insurance provision.

     In the event Grantor fails to cause said taxes and assessments to be paid or to cause the Property to be insured, then Beneficiary may pay said taxes and assessments, redeem the Property from any tax sale and insure the Property at the expense of Grantor but only after having given to Grantor written notice of and a thirty (30) day period in which to cure such failure.

     In the event of loss or damage to the Property by fire or other hazard, Grantor will give immediate notice to Beneficiary, who may make proof of loss if not made promptly by Grantor.

     Assignments of Leases and Rents. As additional security, Grantor hereby assigns to Beneficiary all rents accruing on the Property. Grantor shall have the right to collect and retain the rents until the occurrence of an Event of Default (as defined in the Loan Agreement). Upon the occurrence of an Event of Default, Beneficiary in person, by an agent or by a judicially appointed receiver shall be entitled to enter upon, take possession of and manage the Property and collect the rents. All rents so collected shall be applied first to the costs of managing the Property and collecting the rents, including fees for a receiver and an attorney, commissions to rental agents, repairs and other necessary related expenses and then to payments on the amount of the Secured Obligations then remaining unpaid.

     Maintenance of Property. Grantor agrees to cause the Property to be kept in the condition required in the Loan Agreement and in compliance with all governmental laws, rules and regulations and shall not permit or commit any removal, waste, impairment, deterioration, demolition, alteration or abandonment thereof or permit any use of the Property in violation of any law, in a manner which could invalidate any insurance on the Property, or which could result in an uninsured loss.

     Advances. Beneficiary shall have the right, but not the obligation, to make any payment or take any action for which Grantor is obligated hereunder, but only after having given to Grantor written notice of and a thirty (30) day period in which to make such payment or take such action. Any amount or expense, or other obligation paid or incurred by Beneficiary for or on behalf of Grantor (including, but not limited to, taxes, assessments, and other obligations, insurance premiums, expenses of managing the Property, costs of repairs or improvements, attorneys’ fees, court costs and Trustee’s fees) shall be included within the definition of the term “Secured Obligations,” shall be secured hereby and shall be due and payable by Grantor upon demand by Beneficiary.

     Condemnation. Any and all judgments, awards of damages and settlements resulting from any and all actual or threatened condemnation proceedings with respect to or for any damage (whether caused by such condemnation or otherwise) to the Property or any part thereof shall be disbursed and used in accordance with the terms of the Loan Agreement. Grantor shall promptly give Beneficiary notice of any actual or threatened condemnation proceeding which may affect the Property.

     Power of Sale. This conveyance, however, is in trust to secure the payment and performance of the Secured Obligations. If an Event of Default has occurred then all of the Secured Obligations shall, at the option of Beneficiary, be and become at once due and payable with notice to Grantor, and Trustee shall, at the request and at the option of Beneficiary, sell the Property or a sufficiency thereof, to satisfy the Secured Obligations at public outcry to the highest bidder for Cash or on such other terms as Trustee may elect. “Cash” can include wire transfers, bank checks and other forms of present payment acceptable to Trustee and Beneficiary. Sale of the Property shall be advertised for three consecutive weeks preceding the sale in a newspaper published in the county where the Property is situated, or if none is so published, then in some newspaper having a general circulation therein, and by posting notice of sale for the same time at the courthouse of the same county. The notice and advertisement shall disclose the names of the original Grantor in this Deed of Trust. Grantor waives the provisions of Section 89-l-55 of the Mississippi Code of 1972, and Section 111 of the Constitution of the State of Mississippi, as far as such provisions restricts the right of Trustee to offer at sale more than 160 acres at a time, and Trustee may offer the Property herein conveyed as a whole, regardless of how it is described. If the Property is situated in two or more counties, or in two judicial districts of the same county, Trustee shall have full power to select in which county, or judicial district, the sale of the Property is to be made, newspaper advertisement published and notice of sale posted, and Trustee’s selection shall be binding upon Grantor and Beneficiary. The Chief Financial Officer of the Beneficiary may declare Grantor to be in default and request Trustee to sell the Property. Beneficiary shall have the same right to purchase the Property at the foreclosure sale as would a purchaser who is not a party to this Deed of Trust. At Beneficiary’s direction, Trustee can offer and sell all or any part of the Property subject to any leases, easements or other encumbrances, whether or not listed on Exhibit “B”. At any sale hereunder, Trustee may, from time to time, adjourn said sale to a later time or date and from time to time and date to date without readvertising the sale by giving notice of the time and place of such continued sale at the time Trustee shall make said adjournment. Trustee shall have full power to conduct any sale hereunder through an agent duly appointed by him for that purpose and said appointment need not be in writing or recorded. Trustee may determine any details of sale not specified herein. Out of the proceeds arising from said sale, the costs and expenses of preparing

the Property for and conducting the sale and enforcing this Deed of Trust, including a reasonable Trustee’s fee, the attorneys’ fee prescribed in the Transaction Documents and this Deed of Trust, and all reasonable costs and expenses of any person engaged to inspect the Property or to examine or insure title thereto, shall first be paid, next, the amount of the Secured Obligations then remaining unpaid shall be paid, and, lastly, any balance remaining shall be paid to Grantor or to any other person lawfully entitled thereto. The power of sale granted hereunder may be exercised, at Beneficiary’s discretion, as to all or any part of the Property. Neither institution of suit on the Secured Obligations or any part thereof nor exercise of the power of sale granted hereunder as to less than all of the Property shall affect this Deed of Trust as to the Property not sold pursuant to the power of sale granted hereunder. Any facts stated in the notice of sale and the trustee’s deed shall be deemed presumptively correct.

     Defeasance. If the Secured Obligations are paid and performed in full, Beneficiary agrees to cancel this Deed of Trust upon the records. Grantor agrees to pay all usual and necessary costs incident to such cancellation.

     Event of Default; Remedies. If an Event of Default shall have occurred and be continuing or if at any time Beneficiary in good faith deems it necessary to protect its interest under this. Deed of Trust, Beneficiary may, in addition to its ability to invoke the power of sale provisions hereunder and to exercise the other remedies provided for in this Deed of Trust and other Loan Documents, terminate Grantor’s license to collect and receive the rents, revenues and profits, and, in addition, Beneficiary personally, by an agent or by judicially appointed receiver, shall have the right to forthwith enter upon, take possession of and manage the Property or any part thereof To the extent permitted by applicable law, Grantor waives notice of Beneficiary’s application for a receiver and of the necessity of Beneficiary or the receiver posting bond. The rents, revenues and profits shall be applied, first, to the costs incurred by Beneficiary and its agents and contractors in managing the Property or any part thereof and collecting the rents, revenues and profits, including fees and commissions to agents and attorneys, and the costs of any repairs and expenses incurred by Beneficiary in leasing or preparing the Property or any part thereof for lease and then to the Secured Obligations in such manner as Beneficiary may elect. All remedies provided to Beneficiary under this Deed of Trust are cumulative and not exclusive and are in addition to any other remedies available to Beneficiary by agreement or applicable law.

     Appointment of Successor Trustee. Beneficiary may without notice to any party to this Deed of Trust or to their successors or assigns, and without regard to the willingness or inability of Trustee to act, or to execute this trust, appoint another person or succession of persons to act as trustee herein, and such appointee or substitute shall have all the title, authority and powers in the execution and enforcement of this trust as are vested in Trustee. If Beneficiary be a corporation or other entity, such appointment may be made by any one of its officers, agents or other persons authorized to act on behalf of the entity. No one exercise of this power of appointment, the power of sale, or any other power or right given in this Deed of Trust shall exhaust the right to exercise such power, but all rights and powers herein given may be exercised as often as may be necessary to achieve the collection of all amounts and the performance of all Secured Obligations secured by this Deed of Trust until said amounts and Secured Obligations are fully, finally and indefeasibly paid and discharged. Trustee shall not be liable for any error of judgment or act done by Trustee in good faith. Trustee shall have the right to resign at any time.

     First Lien; Subordinate Indebtedness. Any Secured Obligation at any time secured hereby may be extended, rearranged or renewed without in anywise altering, varying or diminishing the force, effect or lien of this Deed of Trust. Grantor shall not create or suffer to exist any lien of any nature on the Property other than a lien for ad valorem taxes not yet due and payable, the lien of this Deed of Trust. If Grantor shall, with Beneficiary’s prior written consent, grant or there shall otherwise be created any lien of any nature on the Property junior to this Deed of Trust, Grantor shall perform its obligations under such junior lien. Further such junior lien shall be subject to the condition that the time for the payment of the Secured Obligations hereby secured and the manner and amount of payment thereof, the benefits of the security afforded hereby or any obligation contained in an instrument substituted therefor, may, without the consent of such junior lienholder, and without any obligation to give notice of any kind thereto, be changed, increased, extended or suspended on any terms whatsoever.

     Successors and Assigns. The agreements herein contained shall be binding upon Grantor and its heirs, executors, administrators, successors, and assigns and inure to the benefit of Beneficiary and its successors and assigns.

     Further Assurances. Grantor, upon request of Beneficiary, will execute and file any further documents as may be necessary, desirable or proper to correct any defect, error or omission which may be discovered herein or in any other document executed in connection herewith, to carry out more effectively the purposes of this Deed of Trust or to subject to the lien and security interest hereof any property intended to be covered hereby.

     Pronouns. Whenever used herein, the singular number shall include the plural, the plural the singular, the use of any gender shall be applicable to all genders, and the term “Beneficiary” shall include any payee of the Note secured hereby or any legal holder or other transferee thereof whether by operation of law or otherwise. Whenever used herein, the term “Grantor” shall include all grantors collectively and any one of the grantors individually, and all liability shall be joint and several.

     Governing Law. This Deed of Trust shall be governed by the laws of Mississippi and the applicable laws of the United States of America.

     Severability. The unenforceability or invalidity of any provision(s) of this Deed of Trust shall not render any other provision(s) hereof unenforceable or invalid.

     Notices. All notices and other communications required or permitted to be given pursuant to this Deed of Trust (except for notices of a foreclosure sale which shall be given in the manner set forth above) shall be given in the same manner, to the same addresses and shall be deemed delivered, all as set forth in the Loan Agreement.

     Nonwaiver. A failure on the part of Beneficiary to exercise any remedy or option contained in this Deed of Trust in the Event of Default shall not constitute a waiver of Beneficiary’s right to exercise said remedy or option in the event of any subsequent default.

     Entire Agreement; Amendment. This Deed of Trust, the Loan Agreement and other Transaction Documents contain the entire agreement between Grantor and Beneficiary relating to the subject matter hereof and all prior agreements related thereto which are not

contained herein are terminated. This Deed of Trust may be amended, revised, waived, discharged, released or terminated, in whole or in part, only by a written instrument executed by the party against which enforcement of the amendment, revision, waiver, discharge, release or termination is asserted.

     Counterparts. This Deed of Trust may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute but one instrument.

     Definitions. All capitalized terms used herein without definition shall have the respective meanings provided therefor in the Loan Agreement.

     Fixture Filing. This Deed of Trust is also a financing statement filed as a fixture filing as to goods that are or may become fixtures related to the Property.

     Release of Collateral. Beneficiary can release all or part of the Property and the Fixtures from the security interest created by this Deed of Trust without releasing Grantor or any guarantor from any liability under any of the Secured Obligations or any guaranty of any of the Secured Obligations.

     Waiver of Marshalling. Grantor disclaims and waives any obligation of Beneficiary to marshal assets or sell in the inverse order of alienation in the course of Beneficiary exercising its rights under the Loan Documents.

     IN WITNESS WHEREOF, Grantor has executed this instrument on the date beneath its signature and effective as of the date first above written.

PROMISSORY NOTE

Date: _______________, 2011		$75,000,000.00

     FOR VALUE RECEIVED, Kior, Columbus, LLC., (the “Borrower”), hereby promises to pay to the order of the Mississippi Development Authority (the “Lender”) or its assigns, the principal sum of Seventy Five Million Dollars ($75,000,000.00) until fully and finally paid, and all other amounts payable by the Borrower under the Loan Agreement (as hereinafter defined).

     This Note has been executed under and pursuant to a Loan Agreement dated as of this date between the Lender and the Borrower (the “Agreement”), which Agreement is incorporated herein in its entirety by reference. This Note is issued to evidence the obligation of the Borrower under the Agreement to repay the loan made by the Lender and all other payments of any kind required to be paid by the Borrower under the Agreement. The Agreement includes provisions for prepayment and acceleration of this Note. In the event that the terms of this Note conflict with the terms of the Agreement, the terms of the Agreement shall control.

     The principal payments on the Loan shall be due semi-annually on the 30^th day of June and the 31^st day of December of each year in installments sufficient to repay the total loan within a period of time determined by the weighted average life of the equipment being purchased or twenty (20) years, whichever is less, commencing on the earlier of December 31, 2012 or the next scheduled payment date that is at least six months after the Start of Commercial Production (as defined in the MOU) (“weighted averaged life” shall mean the result of finding the sum of the products produced by multiplying the cost of each piece of Loan-financed equipment by its useful life and then dividing such sum by the total cost of all Loan-financed equipment). The entire amount of the outstanding principal balance and all other applicable costs, charges or expenses is due and payable no later than the date which is twenty (20) years from the date of the initial repayment of the loan proceeds hereunder by the Borrower. Provided the first payment is prior to completion of Borrower’s annual financial statement audit, Borrower will estimate the first payment and will perform a final payment calculation after completion of the audit. Borrower will adjust the second payment to reflect any adjustment resulting from the post-audit payment calculation. Equipment lives will be determined by applying the capitalization and depreciation policy it uses for preparation of its audited financial statements. Prior to the June payment each year, the payment amount will be recalculated based on the principal amount due and owing at that time. All payments shall be payable in coin or currency of the United States of America which, at the time of payment is legal tender for the payment of the Loan and shall be made by the Borrower to the Lender by check delivered and received on payment date or by bank wire or bank transfer as Lender may specify or approve.

     As provided in the Agreement and subject to the provisions thereof, payments hereon are to be made at the principal office of the Lender as shown in the Agreement in an amount which

together with other monies available therefore pursuant to the Agreement, will equal the amount payable as principal due on the Loan (as defined in the Agreement) on such due dates.

     The Borrower shall make payments on this Note on the dates and in the amounts as calculated each year as provided herein and in the Agreement and in addition shall make such other payments as are required pursuant to the Agreement. Upon the occurrence and during the continuance of an Event of Default, as defined in the Agreement, the principal on this Note may be declared immediately due and payable as provided in the Agreement. Upon any such declaration the Borrower shall pay all costs, disbursements, expenses and reasonable counsel fees of the Lender in seeking to enforce their rights under the Agreement and this Note.

     The Borrower (a) waives diligence, demand, presentment for payment, notice of nonpayment, protest and notice of protest, notice of any renewals or extension of this Note, and (b) agrees that the time for payment of this Note may be extended at the sole discretion of the Lender without impairing the Borrower’s liability hereon. Any delay on the part of the Lender in exercising any right hereunder shall not operate as a waiver of any such right, and any waiver granted with respect to one default shall not operate as a waiver in the event of any subsequent or continuing default.

     This Note shall be governed and construed in accordance with the laws of the State of Mississippi.

     IN WITNESS WHEREOF, the undersigned has caused this Note to be executed in its name and, if applicable, its corporate seal to be hereunto affixed and attested to by its duly authorized officers all as of the day and year first above written.

     IN ALL RESPECTS, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY, AND PERFORMANCE, THIS AGREEMENT SHALL BE GOVERNED BY, CONSTRUED, AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF MISSISSIPPI, WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES, AND ANY APPLICABLE LAWS OF THE UNITED STATES OF AMERICA.
