Section 2.01. Issuance of the Letter of Credit. Upon the terms, subject to the conditions and relying upon the representations and
warranties set forth in this Agreement or incorporated herein by reference, the Bank agrees to issue the Letter of Credit (substantially in the form of Appendix I hereto). The Letter of Credit shall be in the original stated amount of
$101,315,069, which is the sum of (i) the principal amount of the Bonds outstanding on the Closing Date, plus (ii) interest thereon computed at 12% per annum for a period of 40 days (on the basis of a 365 day year). 

Section 2.02. Letter of Credit Drawings. The Bond Trustee is authorized to make drawings under the Letter of Credit in accordance
with the terms thereof. No drawing shall be made under the Letter of Credit for the payment of principal of or interest on Ineligible Bonds. The Company hereby directs the Bank to make payments under the Letter of Credit in the manner therein
provided. The Company, hereby irrevocably approves reductions and reinstatements of the Principal Component and the Interest Component (as each term is defined in the Letter of Credit) of the Letter of Credit as provided in the Letter of Credit.

 Section 2.03. Reimbursement of Liquidity Drawings under the Letter of Credit; Mandatory Redemption; Interest. 

(a) Each Liquidity Drawing paid under the Letter of Credit shall, at the time of drawing, constitute an advance
(“Liquidity Advance”) to the Company. The Company promises to pay to the Bank the portion of each Liquidity Advance representing the interest component of the purchase price of the Bonds (or a pro rata portion thereof in the event
of a partial remarketing or purchase of such Bonds on the date specified in (iv) below), including interest thereon, on the earlier of (i) subject to Section 2.03(b) hereof, the
30th day following the date such Liquidity Advance is made, (ii) the Conversion Date, (iii) the date on which the Bonds purchased in connection with such Liquidity Drawing are redeemed
pursuant to the Bond Indenture, (iv) the date on which such Bonds, or portions thereof, are remarketed by the Remarketing Agent on behalf of the Company or purchased by the Company or otherwise sold at the direction of the Bank, (v) the
regularly scheduled Interest Payment Date for the Bonds next succeeding the date on which such Liquidity Advance was made and (vi) the date on which the Letter of Credit is replaced by a Substitute Credit Facility in accordance with the terms
of Section 2.07 hereof. The Company promises to pay to the Bank the portion of each Liquidity Advance representing the principal component of the purchase price of the Bonds (or a pro rata portion thereof in the event of a partial remarketing
or purchase of Bonds on the date specified in (iv) below), including interest thereon (in accordance with the immediately preceding sentence), on the earlier of (i) subject to Section 2.03(b) hereof, the 30th day following the date such Liquidity Advance is made, (ii) the Conversion Date, (iii) the date on which the Bonds purchased in connection with such Liquidity Drawing are redeemed pursuant
to the Bond Indenture, (iv) the date on which such Bonds, or portions thereof, are remarketed or purchased by the Company, or otherwise sold at the direction of the Bank, or (v) the date on which the Letter of Credit is replaced by a
Substitute 

  
 -9- 

 
Credit Facility in accordance with the terms of Section 2.07 hereof. The Company promises to pay to the Bank interest on the unpaid principal amount of each Liquidity Advance from the date
such Liquidity Advance is made until such Liquidity Advance is paid in full as provided herein, at a rate per annum equal to the Base Rate from time to time in effect, payable in arrears. Such interest shall be payable monthly on the first day of
each calendar month (and if such day is not a Business Day or the next succeeding Business Day) and on the date on which such Liquidity Advance is payable in full as provided herein. Any Liquidity Advance not paid when due shall, at the option of
the Bank, bear interest at the Default Rate. 
 (b) Any Liquidity Advance created pursuant to paragraph (a) above may be
prepaid in whole or in part at any time without premium or penalty on any Business Day. 
 (c) During such time as the Bonds
constitute Pledged Bonds, the Bank shall have all of the rights granted to an Owner under the Bond Indenture and such additional rights as may be granted to the Bank hereunder. The obligation of the Company to pay each Liquidity Advance shall be
satisfied by the payments of principal and interest on the Bonds which were delivered in respect of such Liquidity Advance, according to their terms, the terms of the Bond Indenture, and the terms hereof. To the extent the Bank (or a custodian on
behalf of the Bank) actually receives payment in respect of principal of or interest on any Bond held by the Bank, including pursuant to subsection (a) above or subsection (d) below, the Liquidity Advance made in connection with the
purchase of such Bond shall be deemed to have been reduced pro tanto, with the Bank crediting any interest payment on the Bond received by the Bank (or a custodian on behalf of the Bank) first to the payment of interest on such Liquidity
Advance and then to the payment of principal thereof and crediting any principal repayment received to the principal thereof. 

(d) As collateral security for the prompt and complete payment when due of all Obligations, the Company hereby pledges,
assigns, hypothecates, transfers and delivers to the Bank all its right, title and interest to, and hereby grants to the Bank a first lien on, and security interest in, all right, title and interest of the Company in and to the following (the
“Pledged Bond Collateral”): 
 (i) all Pledged Bonds; 

(ii) all income, earnings, profits, interest, premium or other payments in whatever form in respect of the Pledged Bonds; 

(iii) all proceeds (cash and non-cash) arising out of the sale, exchange, collection, enforcement or other disposition of all
or any portion of the Pledged Bonds; 
 The Company, covenants that the pledge, assignment and taking of “control” of the Pledged Bonds (within
the meaning of Section 8-106(d) of the Uniform Commercial Code) will create a valid, perfected (to the extent such Pledged Bonds constitute “security entitlements” as defined in the Uniform Commercial Code), first priority security
interest in all right, title or interest of the Company in or to such Collateral, and the proceeds thereof, subject to no prior Lien. Upon the 

  
 -10- 

 
occurrence of any Event of Default, in addition to the rights and remedies granted to the Bank hereunder, the Bank shall have with regard to the Pledged Bond Collateral all rights and remedies of
a secured party under the applicable Uniform Commercial Code. Upon (a) the remarketing of any Pledged Bonds, (b) the receipt by the Bank of the proceeds of such remarketing, and (c) the delivery by the Bond Trustee to the Bank of a
Reinstatement Certificate in the form of Exhibit E to the Letter of Credit with respect to such remarketing, Pledged Bonds in an aggregate principal amount equal to the lesser of the following shall automatically be released from the foregoing
pledge and security interest: (i) the amount shown in paragraph 3 of such Reinstatement Certificate as representing principal amount of proceeds of the sale of remarketed Pledged Bonds, and (ii) the amount shown in paragraph 2 of such
Reinstatement Certificate as representing principal of the purchase price of Bonds which became Pledged Bonds. At such time as the Company reimburses the Bank under hereunder for the full amount of Liquidity Advances to purchase Pledged Bonds,
together with all accrued interest thereon payable in accordance with the terms hereof, the Bank shall provide such instructions to the Bond Trustee and take such steps as may be reasonably requested by the Company to cause such Pledged Bonds to be
transferred to the Company, whether through registration by the Bond Trustee in the name of the Company or through the book-entry system. 

Section 2.04. Reimbursement of Drawings Other than Liquidity Drawings Creating Liquidity Advances under the Letter of
Credit. The Company agrees to immediately reimburse (or cause to be immediately reimbursed) the Bank for the full amount of any drawings made under the Letter of Credit, excluding Liquidity Drawings, on the date of payment of each such
drawing. If the Company does not make such reimbursement on such date, the Reimbursement Obligation of the Company shall, at the option of the Bank, bear interest at the Default Rate, payable on demand; provided, however, that in no event
shall the Default Rate exceed the Maximum Rate. 
 Section 2.05. Fees. The Company hereby agrees to perform the obligations
provided for in the Fee Letter, including, the payment of any and all fees provided for therein. The terms of the Fee Letter are incorporated by reference herein. 

Section 2.06. Method of Payment, Etc. All payments to be made by the Company under this Agreement shall be made to the Bank not
later than 2:00 p.m. on the date when due and shall be made in lawful money of the United States of America and in immediately available funds. 

Section 2.07. Substitute Letter of Credit. The Company agrees that any termination of the Letter of Credit as a result of the
provision of any Substitute Credit Facility will require, as a condition thereto, that the Company or the issuer of any Substitute Credit Facility will provide funds on the date of such termination or provision, which funds will be sufficient to pay
in full at the time of termination of such Letter of Credit all Obligations due and owing to the Bank hereunder. 
 Section 2.08.
Computation of Fees and Interest; Default Rate. 
 (a) All computations of fees payable under this Agreement shall be
made on the basis of a three hundred sixty (360) day year and actual days elapsed. All computations of interest payable under the Agreement shall be computed on the basis of a 

  
 -11- 

 
year of 365 or 366 days, as applicable, and actual days elapsed. Interest and fees shall accrue during each period during which interest or fees, as applicable, is computed from and
including the first day thereof to but excluding the last day thereof. Each determination by the Bank of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error. 

(b) If any amount payable by the Company hereunder or under the Fee Letter is not paid when due (without regard to any
applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter, at the option of the Bank, bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate. 

Section 2.09. Payment Due on Non-Business Day to Be Made on Next Business Day. If any sum
becomes payable pursuant to this Agreement on a day which is not a Business Day, the date for payment thereof shall be extended, without penalty, to the next succeeding Business Day, and such extended time shall be included in the computation of
interest and fees. 
 Section 2.10. Source of Funds. All payments made by the Bank pursuant to the Letter of Credit shall be
made from funds of the Bank and not from any other Person. 
 Section 2.11. Evidence of Debt. The Reimbursement Obligations
shall be evidenced by one or more accounts or records maintained by the Bank in the ordinary course of business. The accounts or records maintained by the Bank shall be conclusive absent manifest error of the amount of the Reimbursement Obligations
owing by the Company and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Company hereunder to pay any amount owing with respect to the
Obligations. 
 Section 2.12. Extension of Stated Expiration Date. The Stated Expiration Date may be extended by the Bank, at
its option and in its sole discretion, for an additional period acceptable to the Bank, upon the written request of the Company received by the Bank no earlier than one hundred eighty (180) days and no later than sixty (60) days prior to
the Stated Expiration Date then in effect. If the Bank, in its sole discretion, elects to extend the Stated Expiration Date, the Bank shall deliver to the Bond Trustee a Notice of Extension (herein referred to as a “Notice of
Extension”) within thirty (30) days following the receipt of such written request designating the date to which the Stated Expiration Date is being extended. Failure to deliver a Notice of Extension by the Bank within such
thirty (30) day period shall be deemed to be a decision by the Bank not to extend the Stated Expiration Date. Subject to the last sentence of this Section, such extension of the Stated Expiration Date shall be effective, immediately upon
receipt of such Notice of Extension and thereafter all references in this Agreement to the Stated Expiration Date shall be deemed to be references to the date designated as such in the most recent Notice of Extension delivered to the Bond Trustee.
Any date to which the Stated Expiration Date has been extended in accordance with this Section 2.12 may be further extended in like manner. 

Section 2.13. Amendments upon Extension. Upon any extension of the Stated Expiration Date pursuant to Section 2.12 hereof,
the Bank and the Company reserve the right to renegotiate any provision hereof; provided, however, any amendments reflecting such renegotiation shall be subject to the provisions of Section 8.01 hereof.

 ARTICLE III 

TAXES AND YIELD PROTECTION 

Section 3.01. Taxes. If any payments to the Bank under this Agreement are made from outside the United States, the Company will
not deduct any foreign taxes from any payments it makes to the Bank. If any such taxes are imposed on any such payments made by the Company (including payments under this paragraph), the Company will pay the taxes and will also pay to the Bank, at
the time interest is paid, any additional amount which the Bank specifies as necessary to preserve the after-tax yield the Bank would have received if such taxes had not been imposed. The Company will confirm that it has paid the taxes by giving the
Bank official tax receipts (or notarized copies) within thirty (30) days after the due date. 
 Section 3.02. Increased Costs.

 (a) Increased Costs Generally. If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement
against assets of, deposits with or for the account of, or credit extended or participated in by, the Bank; 
 (ii) subject
any Recipient to any taxes (other than on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto); or 

(iii) impose on the Bank or the London interbank market any other condition, cost or expense affecting this Agreement, the Fee
Letter or the Letter of Credit or any participation therein; 
 and the result of any of the foregoing shall be to increase the cost to the
Bank of issuing or maintaining the Letter of Credit, or to reduce the amount of any sum received or receivable by the Bank hereunder (whether of principal, interest or any other amount) then, upon request of the Bank, the Company will pay to the
Bank such additional amount or amounts as will compensate the Bank for such additional costs incurred or reduction suffered. 

(b) Capital Requirements. If the Bank determines that any Change in Law affecting the Bank or the Bank’s holding
company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on the Bank’s capital or on the capital of the Bank’s holding company, if any, as a consequence of this Agreement, the
Fee Letter or the Letter of Credit issued by the Bank, to a level below that which the Bank or the Bank’s holding company could have achieved but for such Change in Law (taking into consideration the Bank’s policies and the policies of the
Bank’s holding company with respect to capital adequacy), then from time to time the Company will pay to the Bank such additional amount or amounts as will compensate the Bank or the Bank’s holding company for any such reduction suffered.

  
 -13- 

 (c) Certificates for Reimbursement. A certificate of the Bank setting
forth the amount or amounts necessary to compensate the Bank or its holding company, as the case may be, as specified in subsection (a) or (b) of this Section and delivered to the Company shall be conclusive absent manifest error. The
Company shall pay the Bank the amount shown as due on any such certificate within ten (10) days after receipt thereof. 

(d) Delay in Requests. Failure or delay on the part of the Bank to demand compensation pursuant to the foregoing
provisions of this Section shall not constitute a waiver of the Bank’s right to demand such compensation; provided that the Company shall not be required to compensate the Bank pursuant to the foregoing provisions of this Section for any
increased costs incurred or reductions suffered more than six (6) months prior to the date that the Bank notifies the Company of the Change in Law giving rise to such increased costs or reductions and of the Bank’s intention to claim
compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six (6) month period referred to above shall be extended to include the period of retroactive effect thereof).

 (e) Mitigation Obligation. If the Bank requests compensation under this Section 3.02, or requires the Company
to pay any additional amounts to pursuant to Section 3.01, then at the request of the Company the Bank shall use reasonable efforts to designate a different lending office for booking the Obligations hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of the Bank, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.02 as the case may be, in
the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not subject the Bank to any unreimbursed cost or expense and would not otherwise be disadvantageous to the Bank. The
Company hereby agrees to pay all reasonable costs and expenses incurred by the Bank in connection with any such designation or assignment. 

Section 3.03. Survival. All of the Company’s obligations under this Article III shall survive the termination of this
Agreement, the cancellation of the Letter of Credit and the repayment, satisfaction or discharge of all other Obligations.

the making of any Liquidity Advance hereunder, and shall continue in full force and effect as long as any Liquidity Advance or any other Obligation hereunder shall remain unpaid or unsatisfied or the Letter of Credit shall remain outstanding. 

Section 8.12. Severability. If any provision of this Agreement or the other Related Documents is held to be illegal, invalid or
unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Related Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith
negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a
particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

SCRANTON, PENNSYLVANIA 18507

 IRREVOCABLE LETTER OF CREDIT NO. 68104173

 The Bank of New York Mellon Trust Company, N.A., as Trustee 

601 Travis Street, 16th Floor 

Houston, Texas 77002 
 Attn: Kathlyn Shen 

At the request and on the instructions of our customer, REG Geismar, LLC, a Delaware limited liability company formerly known as
Dynamic Fuels, LLC (the “Company”), to secure the obligations of the Company with respect to the Bonds (as hereinafter defined), Bank of America, N.A., (the “Bank”) hereby establishes in your favor, as Trustee under
the Indenture of Trust (the “Trustee”), dated as of October 1, 2008 (the “Indenture”) between the Louisiana Public Facilities Authority (the “Issuer”) and you pursuant to which $100,000,000 in
aggregate principal amount of the Issuer’s Revenue Bonds (Dynamic Fuels, LLC Project) Series 2008 (the “Bonds”) have been issued, this Irrevocable Letter of Credit in the initial amount of $101,315,069 (hereinafter, as reduced
from time to time in accordance with the provisions hereof, the “Stated Amount”) of which (i) an amount not exceeding $100,000,000 (as reduced from time to time in accordance with the terms hereof, the “Principal
Component”), may be drawn upon with respect to payment of the unpaid principal amount or the portion of Purchase Price corresponding to principal of the Bonds, and (ii) an amount not exceeding $1,315,069 (as reduced from time to time
in accordance with the terms hereof, the “Interest Component”) may be drawn upon with respect to payment of interest accrued or the portion of Purchase Price corresponding to interest accrued on the Bonds on or prior to their stated
maturity date, effective immediately and expiring on July 8, 2015, unless terminated earlier in accordance with the provisions hereof or unless otherwise extended (in each case, the “Stated Expiration Date”). All drawings under
this Letter of Credit will be paid with our own funds.  
 Funds under this Letter of Credit will be made available to you
against receipt by us of the following items at the time required below: (a) if the drawing is being made with respect to the payment of the portion of the Purchase Price of Bonds delivered to the Trustee pursuant to Section 4.01 or 4.02
of the Indenture corresponding to the principal thereof (an “A Drawing”), receipt by us of your written certificate in the form of Exhibit A attached hereto appropriately completed and signed by an Authorized Officer; (b) if
the drawing is being made with respect to the payment of principal of the Bonds (a “B Drawing”), receipt by us of your written certificate in the form of Exhibit B attached hereto appropriately completed and signed by an
Authorized Officer; and (c) if the drawing is being made with respect to the payment of interest, or the  

 
portion of Purchase Price corresponding to interest, on the Bonds (a “C Drawing”), receipt by us of your written certificate in the form of Exhibit C attached hereto
appropriately completed and signed by an Authorized Officer. Presentation of such certificate(s) shall be made by facsimile to Bank of America, N.A., Scranton, at facsimile number (800) 755-8743, Attention: Standby Letter of Credit Department,
without further need of documentation, including the original of this Letter of Credit, it being understood that each Payment Document so submitted is to be the sole operative instrument of drawing. You shall use your best efforts to give telephonic
notice of a drawing to the Bank at its Standby Letter of Credit Department, at (800) 370-7519, OPT 1, on the Business Day preceding the day of such drawing (but such notice shall not be a condition to drawing hereunder and you shall have no
liability for not doing so). “Business Day” means any day other than (a) a Saturday or Sunday, (b) a day on which the Trustee or the Bank is required or permitted by law to close and (c) a day on which the New York
Stock Exchange is closed. 
 If a drawing is made by you hereunder at or prior to 12:30 P.M., New York City time, on a Business Day,
and provided that the requirements set forth above have been strictly satisfied and that such drawing and the documents presented in connection therewith conform to the terms and conditions hereof, payment shall be made to you, of the amount
specified in immediately available funds, (i) with respect to a C Drawing to pay interest on the Bonds which has accrued and is due and payable on a stated interest payment date, not later than 2:30 P.M., New York City time, on the next
following Business Day or not later than 2:30 P.M., New York City time, on such later Business Day you may specify, or (ii) with respect to any other drawing, not later than 2:30 P.M., New York City time, on the same Business Day or not later
than 2:30 P.M., New York City time, on such later Business Day as you may specify. Drawings received after 12:30 P.M., New York City time, on a Business Day will be considered as presented at or prior to 12:30 P.M., New York City time, on the
following Business Day. If requested by you, payment under this Letter of Credit will be made by wire transfer to you in immediately available funds or by deposit into a designated account that you maintain with us in accordance with your
instructions. If a demand for payment made by you hereunder does not, in any instance, conform to the terms and conditions of this Letter of Credit, we shall give you prompt notice that the demand for payment was not effected in accordance with the
terms and conditions of this Letter of Credit, stating the reasons therefor and that we will upon your instructions hold any documents at your disposal or return the same to you. Upon being notified that the demand for payment was not effected in
conformity with this Letter of Credit, you may attempt to correct any such non-conforming demand for payment to the extent that you are entitled to do so. 

Demands for payment hereunder honored by us shall not, in the aggregate, exceed the Stated Amount, as the Stated Amount may have been
reinstated by us as provided in the next paragraph. Subject to the preceding sentence, each “A Drawing” and each “B Drawing” honored by the Bank hereunder shall pro tanto reduce the Principal
Component, and each “C Drawing” honored by the Bank hereunder shall pro tanto reduce the Interest Component; any such reduction shall result in a corresponding reduction in the Stated Amount, it being understood
that after the effectiveness of any such reduction you shall no longer have any right to make a drawing hereunder in respect of the amount of such principal and/or interest on the Bonds or the payment of Purchase Price corresponding thereto.

 After payment by us of an A Drawing, in the event of the remarketing of Pledged Bonds (or portions thereof) previously purchased with
the proceeds of an A Drawing, our obligation to 

  
 -2- 

 
honor drawings hereunder shall be automatically reinstated concurrently upon receipt by the Bank of an amount equal to the Purchase Price of such Pledged Bonds (or portion thereof) plus
accrued interest thereon as specified in a certificate in the form of Exhibit E hereto. In addition, (a) the Interest Component shall be reinstated automatically and immediately upon the honoring of a “C Drawing” by the amount
of such drawing and (b) upon the remarketing of the Pledged Bonds, the Interest Component shall be reinstated automatically and immediately upon the Bank’s receipt of a certificate in the form of Exhibit E hereto by the amount referenced
in paragraph 3 of such certificate as representing interest; provided, however, that in no event shall the Interest Component be reinstated to an amount in excess of 40 days’ interest (such amount computed as set forth in the second succeeding
paragraph) on the then applicable Principal Component. 
 Only you or your successor as Trustee may make a drawing under this Letter
of Credit. Upon the payment to you or to your account of the amount demanded hereunder, we shall be fully discharged on our obligation under this Letter of Credit with respect to such demand for payment and we shall not thereafter be obligated to
make any further payments under this Letter of Credit in respect of such demand for payment to you or any other person who may have made to you or makes to you a demand for payment of principal of, Purchase Price of, or interest on, any Bond. By
paying to you an amount demanded in accordance herewith, we make no representation as to the correctness of the amount demanded. 
 This
Letter of Credit applies only to the payment of principal or the portion of Purchase Price of the Bonds corresponding to principal, and up to 40 days’ interest accruing on the Bonds (computed at a rate of 12% per annum on the basis of
actual days elapsed in a 365-day year). Drawings under this Letter of Credit shall apply only to the payment of principal, or the Purchase Price corresponding to principal, and accrued interest on Bonds which are accruing interest at the Daily Rate
or Weekly Rate under the Indenture. 
 Upon the earliest of (a) the honoring by us of the final drawing available to be made
hereunder, (b) our receipt of a certificate signed by an Authorized Officer of the Trustee stating that the conditions precedent to the acceptance of a Substitute Credit Facility (as defined in the Indenture) have been satisfied and that the
Trustee has accepted the Substitute Credit Facility, and setting forth the effective date of said Substitute Credit Facility, (c) our receipt of a certificate signed by an Authorized Officer of the Trustee stating that no Bonds remain
outstanding, (d) 2 Business Days following the first day of the first Commercial Paper Period or the first Long Term Period under the Indenture (each a “Tender Conversion Date”), the occurrence of which Tender Conversion Date
is certified to us in a certificate signed by an Authorized Officer of the Trustee, (e) 15 days (or if such day is not a Business Day, on the next succeeding Business Day) following receipt by the Trustee of a written notice from the Bank of
the occurrence of an event of default under the Reimbursement Agreement dated as of July 8, 2014, between the Company and the Bank, and (f) the Stated Expiration Date, this Letter of Credit shall automatically terminate; provided, however,
that in connection with the termination event described in clause (b), above, this Letter of Credit shall automatically terminate on the second Business Day following the effective date of the Substitute Credit Facility and the honoring by us of the
related drawing hereunder pertaining to the payment of the Purchase Price of the Bonds tendered for purchase on the Mandatory Purchase Date corresponding to the delivery of the Substitute Credit Facility.

 Except for communications given by facsimile as permitted herein (including telephonic
confirmations of facsimile communications), communications with respect to this Letter of Credit shall be in writing and shall be addressed to us at Bank of America, N.A., Mail Code: PA6-580-02-30, 1 Fleet Way, Scranton, Pennsylvania 18507,
Attention: Standby Letter of Credit Department, specifically referring thereon to this Letter of Credit by number. 
 This Letter of Credit
is transferable to any transferee who has succeeded you as Trustee under the Indenture, and may be successively transferred. Any transfer request must be affected by presenting to us the attached form of Exhibit D signed by the transferor and the
transferee together with the original Letter of Credit. Transfers to designated foreign nationals and /or specially designated nationals are not permitted as being contrary to the U.S. Treasury Department or Foreign Assets Control Regulations. Upon
our endorsement of such transfer, the transferee instead of the transferor shall, without necessity of further action, be entitled to all the benefits of and rights under this Letter of Credit in the transferor’s place; provided that, in such
case, any certificates of the Trustee to be provided hereunder shall be signed by one who states therein that he is a duly authorized officer of the transferee. 

As used herein, “Authorized Officer” shall mean any person signing as one of your Vice Presidents, Assistant Vice
Presidents, Trust Officers or Assistant Trust Officers. 
 This Letter of Credit sets forth in full our undertaking, and such
undertaking shall not in any way be modified, amended, amplified or limited by reference to any document, instrument or agreement referred to herein (including, without limitation, the Bonds), except only the certificate(s) referred to herein; and
any such reference shall not be deemed to incorporate herein by reference any document, instrument or agreement except for such certificate(s). 

This credit is issued subject to the International Standby Practices 1998 (“ISP98”). This Letter of Credit shall be
deemed to be issued under the laws of the State of New York and shall, as to matters not governed by ISP98, be governed by and construed in accordance with Article 5 of the Uniform Commercial Code of the State of New York, without regard to conflict
of laws.

 Exhibit 10.2 

SECURITY AGREEMENT (DEPOSIT ACCOUNT/CERTIFICATE OF DEPOSIT) 

THIS SECURITY AGREEMENT (DEPOSIT ACCOUNT/CERTIFICATE OF DEPOSIT) (the “Agreement”) is made and entered into as of this 8th
day of July, 2014, by REG CAPITAL, LLC, an Iowa limited liability company (the “Pledgor”), in favor of BANK OF AMERICA, N.A. (the “Secured Party”). 

RECITALS 
 WHEREAS,
Secured Party has extended credit in the form of an irrevocable transferable direct-pay letter of credit (the “Letter of Credit”) upon the account of REG Geismar, LLC, a Delaware limited liability company (the
“Borrower”). The Letter of Credit is issued pursuant to, and drawings thereunder are repaid in accordance with, the terms of a Reimbursement Agreement dated of even date herewith by and between the Borrower and the Secured Party (as
amended, modified, replaced, renewed or restated from time to time, the “Reimbursement Agreement”); 
 WHEREAS, as a
condition precedent to Secured Party agreeing to issue the Letter of Credit, Pledgor has agreed to establish an interest bearing deposit account in the form of a certificate of deposit issued by Secured Party in an initial amount not less than
$101,315,069, which certificate of deposit shall secure repayment of the Indebtedness (as defined below); and 
 WHEREAS, Pledgor will
benefit, directly or indirectly, from the issuance of the Letter of Credit upon the account of Borrower in that Pledgor and Borrower are commonly owned. 

NOW, THEREFORE, in consideration of the premises and in order to induce Secured Party to issue the Letter of Credit upon the account of
Borrower, Pledgor hereby agrees with Secured Party as follows: 
 Section 1. Grant of Security Interest. To secure payment of
the Indebtedness, Pledgor hereby pledges to Secured Party, and grants to Secured Party a security interest in, the following (the “Collateral”): 

(a) Certificate of Deposit number 424515 issued and established in the name of Pledgor at Secured Party (the “Deposit
Account”); 
 (b) any substitutions for or replacements of the Deposit Account; and 

(c) all Proceeds the foregoing. 

Section 2. Indebtedness. The term “Indebtedness” as used in this Agreement shall mean any and all debts, liabilities,
and obligations of Borrower to Secured Party arising out of or related to the Reimbursement Agreement. 

 Section 3. Maintaining the Deposit Account. So long as any Indebtedness shall remain
unpaid or Secured Party has any commitment or obligation on account of the existence of the Letter of Credit: 
 (a) Pledgor will maintain
the Deposit Account with Secured Party; and 
 (b) it shall be a term and condition of the Deposit Account that except as provided in
Section 4 (concerning releases) and Section 11 (concerning default), no portion of the Collateral shall be paid or released to or for the account of, or withdrawn by or for the account of, Pledgor. 

Section 4. Release of Amounts. So long as no Event of Default as defined in the Reimbursement Agreement shall have occurred and be
continuing, (a) if the value of the Collateral exceeds, at any time the sum of (without duplication) (i) the amount available to be drawn under the Letter of Credit plus (ii) the principal amount of Pledged Bonds (as defined in the
Reimbursement Agreement) (the “Required Funds”), the Secured Party will release any excess funds over the amount of Required Funds upon request by Pledgor (but not more frequently than on a quarterly basis) and (b) at such time
as the Indebtedness has been paid in full and the Letter of Credit has been (x) cancelled and returned to Secured Party or (y) has expired (the “Termination Date”), the Secured Party’s security interest in the
Collateral shall terminate and Secured Party and will follow the instructions of the Pledgor as to the return of the Collateral. 

Section 5. Representations and Warranties. Pledgor represents and warrants to Secured Party as follows: 

(a) Pledgor is a limited liability company that was duly organized under the laws of the State of Iowa and is currently validly existing and
in good standing under the laws of the State of Iowa. 
 (b) The execution, delivery and performance of this Agreement by Pledgor have been
duly authorized by all required limited liability company action. 
 (c) The Person or Persons signing this Agreement on behalf of Pledgor
have been authorized to do so by all requisite limited liability company action. 
 (d) This Agreement is a legal, valid and binding
obligation of Pledgor, enforceable against Pledgor in accordance with its terms, except as such enforceability may be limited by (a) the effect of any applicable Debtor Relief Laws (as such term is defined in the Reimbursement Agreement)
generally, and (b) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 

(e) This Agreement does not conflict with any law, agreement or obligation to which Pledgor is a party or is bound. 

(f) Pledgor is the legal and beneficial owner of the Collateral free and clear of any lien, security interest or other charge or encumbrance
except for the security interest created by this Agreement or otherwise in favor of the Secured Party. 
 (g) Assuming that (i) the
Deposit Account is uncertificated, (ii) the Deposit Account is maintained by the Secured Party and (iii) the Secured Party is a “bank” within the meaning of the Uniform Commercial, then this Agreement creates a valid and
perfected first-priority security interest in the Collateral securing payment of the Indebtedness. 

  
 2 

 (h) No consent of any other Person and no authorization, approval, or other action by, and no
notice to or filing with, any governmental authority or regulatory body is required: (i) for the execution, delivery or performance of this Agreement by Pledgor, (ii) for the perfection or maintenance of the security interest created
hereby (including the first-lien priority nature of such security interest), or (iii) for the exercise by Secured Party of its rights and remedies hereunder, other than (x) those that have already been obtained and are in full force and
effect and (y) after the date hereof, such permits, licenses, authorizations, approvals and entitlements that are required for the lawful conduct of the Pledgor’s business, each of which shall be obtained on or before the date on which it
is required to be obtained where the failure to do so could reasonably be expected to have a material adverse effect. 
 (i) Pledgor has,
independently and without reliance upon Secured Party and based on such documents and information as Pledgor has deemed appropriate, made its own credit analysis of the Borrower and decision to enter into this Agreement. Pledgor shares common
ownership with the Borrower and has determined that the delivery of this Agreement is in its best interests and directly or indirectly benefits the Pledgor. 

(j) After giving effect to this Agreement, Pledgor is Solvent (as defined in the Reimbursement Agreement). 

Section 6. Further Assurances. Pledgor agrees that at any time and from time to time, at the expense of Pledgor, Pledgor will
promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary or desirable, or that Secured Party may reasonably request, in order to perfect and protect the security interest granted hereby
or to enable Secured Party to exercise and enforce its rights and remedies hereunder with respect to any Collateral. 
 Section 7.
Transfers and Other Liens. Pledgor agrees that it will not: (i) assign (by operation of law or otherwise), transfer or otherwise dispose of any of the Collateral, or (ii) create or permit to exist any lien, security interest or
other charge or encumbrance upon or with respect to any of the Collateral, except in each case, for the security interest created by this Agreement or otherwise in favor of the Secured Party. 

Section 8. Authorized Deductions. Pledgor hereby authorizes Secured Party to apply all or any portion of the Collateral to the
immediate payment of any portion of the Indebtedness which is due and owing and unpaid by Borrower upon the occurrence and during the continuance of any Event of Default (as such term is defined in the Reimbursement Agreement). 

Section 9. Failure to Perform. If Pledgor fails to perform any agreement contained herein, Secured Party may itself perform, or
cause performance of, such agreement and the expenses of Secured Party incurred in connection therewith shall be payable by Pledgor under Section 12. 

Section 10. Secured Party’s Duties. The powers conferred on Secured Party hereunder are solely to protect Secured
Party’s interest in the Collateral and shall not impose any duty upon 

  
 3 

 
it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, Secured Party shall have no duty
as to any Collateral, as to ascertaining or taking action with respect to any Collateral, whether or not Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any
parties or any other rights pertaining to any Collateral. Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially
equal to that which Secured Party accords its own property. 
 Section 11. Remedies Upon Default. If any Event of Default (as
defined under the Reimbursement Agreement) under the Reimbursement Agreement shall have occurred and be continuing: 
 (a) Secured Party
may, without notice to Pledgor, and at any time or from time to time, charge, set-off and otherwise apply all or any part of the Collateral against the Indebtedness or any part thereof. 

(b) Secured Party may also exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise
available to it, all the rights and remedies of a secured party on default under the applicable Uniform Commercial Code at that time (the “UCC”) (whether or not the UCC applies to the affected Collateral), and may also, without
notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of Secured Party’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as
Secured Party may deem commercially reasonable. Pledgor agrees that to the extent notice of same shall be required by law, at least ten (10) days’ notice to Pledgor of the time and place of any public sale or the time after which any
private sale is to be made shall constitute commercially reasonable notification. Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Secured Party may adjourn any public or private
sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. 

(c) Any cash held by Secured Party as Collateral and all cash proceeds received by Secured Party in respect of any sale of, collection from,
or other realization upon all or any part of the Collateral may, in the discretion of Secured Party, be held by Secured Party as collateral for, and/or then or at any time thereafter be applied (after payment of any amounts payable to Secured Party
pursuant to Section 12) in whole or in part by Secured Party against, all or any part of the Indebtedness in such order as Secured Party shall elect. Any surplus of such cash or cash proceeds held by Secured Party and remaining after payment in
full of all the Indebtedness shall be paid over to Pledgor or to whomsoever may be lawfully entitled to receive such surplus. 

Section 12. Expenses. Pledgor will, upon demand, pay to Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel, which Secured Party may incur in connection with: (i) the exercise or enforcement of any of the rights of Secured Party hereunder, or (ii) the failure by Pledgor to perform or observe any of the
provisions hereof or the failure of the Borrower to perform or observe any of the provisions of the Reimbursement Agreement. 

  
 4 

 Section 13. Security Interest Absolute. The obligations of Pledgor under this
Agreement are independent of the Indebtedness, and a separate action or actions may be brought and prosecuted against Pledgor to enforce this Agreement, irrespective of whether any action is brought against Borrower or whether Borrower is joined in
any such action or actions. All rights of Secured Party and security interests hereunder, and all obligations of Pledgor hereunder, shall be absolute and unconditional irrespective of: 

(a) any lack of validity or enforceability of the Reimbursement Agreement or the other Related Documents; 

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Indebtedness, or any other amendment or
waiver of or any consent to any departure from the Reimbursement Agreement or the other Related Documents, including, without limitation, any increase in the Indebtedness resulting from the extension of additional credit to Borrower; 

(c) any taking, exchange, release or non-perfection of any other collateral for all or any of the Indebtedness; 

(d) any manner of application of collateral, or proceeds thereof, to all or any of the Indebtedness, or any manner of sale or other
disposition of any collateral for all or any of the Indebtedness or any other assets of Borrower; or 
 (e) any other circumstance which
might otherwise constitute a defense available to, or a discharge of, Borrower or a third party pledgor such as Pledgor (other than payment in full). 

Section 14. Amendments, Etc. No amendment or waiver of any provision of this Agreement, and no consent to any departure by Pledgor
herefrom, shall in any event be effective unless the same shall be in writing and signed by Secured Party, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. 

Section 15. Addresses for Notices. All notices and other communications provided for hereunder shall be in writing (including
telecopier) and mailed, telecopied or delivered to it, if to Pledgor, at its address at 416 South Bell Avenue, Ames, Iowa 50010, and if to Secured Party, at its address at 317 6th Avenue, Suite
200, Des Moines, Iowa 50309, or as to either party, at such other address as shall be designated by such party in a written notice to the other party. All such notices and other communications shall, when mailed or telecopied, be effective when
deposited in the mails or telecopied. 
 Section 16. Continuing Security Interest. This Agreement shall create a continuing
security interest in the Collateral and shall: (i) remain in full force and effect until the Termination Date, (ii) be binding upon Pledgor, its successors and assigns, and (iii) inure to the benefit of, and be enforceable by, Secured
Party and its successors, transferees and assigns. Upon the Termination Date, the security interest granted hereby shall terminate and all rights to 

  
 5 

 
the Collateral shall revert to Pledgor. Upon any such termination, Secured Party will, at Pledgor’s expense, return to Pledgor such of the Collateral as shall not have been applied to the
Indebtedness pursuant to the terms hereof and execute and deliver to Pledgor such documents as Pledgor shall reasonably request to evidence such termination. 

Section 17. Additional Third Party Pledgor Representations and Waivers. Pledgor hereby makes the additional representations,
warranties and agreements set forth below: 
 (a) Representations and Warranties. Pledgor represents and warrants to Secured Party
that: (i) this Agreement is executed at Borrower’s request; (ii) this Agreement complies with all agreements between Pledgor and any Borrower regarding Pledgor’s execution hereof; (iii) Secured Party has made no
representation to Pledgor as to the creditworthiness of Borrower; and (iv) Pledgor has established adequate means of obtaining from Borrower on a continuing basis financial and other information pertaining to Borrower’s financial
condition. Pledgor agrees to keep adequately informed from such means of any facts, events or circumstances which might in any way affect Pledgor’s risks hereunder. Pledgor further agrees that Secured Party shall have no obligation to disclose
to Pledgor any information or material about Borrower which is acquired by Secured Party in any manner. The liability of Pledgor hereunder shall be reinstated and revived, and the rights of Secured Party shall continue if and to the extent that for
any reason any amount at any time paid on account of any Indebtedness is rescinded or must otherwise be restored by Secured Party, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, all as though such amount had not
been paid. The determination as to whether any amount so paid must be rescinded or restored shall be made by Secured Party in its sole discretion; provided, however, that if Secured Party chooses to contest any such matter at the
request of Pledgor, Pledgor agrees to indemnify and hold Secured Party harmless from and against all costs and expenses, including reasonable attorneys’ fees expended or incurred by Secured Party in connection therewith, including, without
limitation, in any litigation with respect thereto. 
 (b) Waivers. 

(i) Pledgor waives any right to require Secured Party to: (A) proceed against Borrower or any other Person;
(B) marshal assets or proceed against or exhaust any security held from Borrower or any other Person; (C) give notice of the terms, time and place of any public or private sale or other disposition of personal property security held from
Borrower or any other Person; (D) take any other action or pursue any other remedy in Secured Party’s power; or (E) make any presentment or demand for performance, or give any notice of nonperformance, protest, notice of protest or
notice of dishonor hereunder or in connection with any obligations or evidences of indebtedness held by Secured Party as security for or which constitute in whole or in part the Indebtedness, or in connection with the creation or new or additional
obligations. 
 (ii) Pledgor waives any defense to its obligations hereunder based upon or arising by reason of: (A) any
disability or other defense of Borrower or any other Person; (B) the cessation or limitation from any cause whatsoever, other than payment in full, of any Indebtedness; (C) any lack of authority of any officer,

  
 6 

 
director, partner, agent or any other Person acting or purporting to act on behalf of Borrower, or any defect in the formation of Borrower; (D) the application by Borrower of the proceeds of
any Indebtedness for purposes other than the purpose represented by Borrower to, or intended or understood by, Secured Party or Pledgor; (E) any act or omission by Secured Party which directly or indirectly results in or aids the discharge of
Borrower or any portion of any Indebtedness by operation of law or otherwise, or which in any way impairs or suspends any rights or remedies of Secured Party against Borrower; (F) any impairment of the value of any interest in any security for
the Indebtedness or any portion thereof, including, without limitation, the failure to obtain or maintain perfection or recordation of any interest in any such security, the release of any such security without substitution, and/or the failure to
preserve the value of, or to comply with applicable law in disposing of, any such security; (G) any modification of any Indebtedness, in any form whatsoever, including, without limitation, the renewal, extension, acceleration or other change in
time for payment of, or other change in the terms of, any Indebtedness or any portion thereof, including increase or decrease of the rate of interest thereon; or (H) any requirement that Secured Party give any notice of acceptance of this
Agreement. Until all Indebtedness shall have been paid in full, Pledgor shall not have any right of subrogation on account of any payment made from the Collateral with respect to the Indebtedness, and Pledgor waives any right to enforce any remedy
which Secured Party now has or may hereafter have against Borrower or any other Person on account of such payment, and waives any benefit of, or any right to participate in, any security now or hereafter held by Secured Party. Pledgor further waives
all rights and defenses it may have arising out of: (1) any election of remedies by Secured Party, even though that election of remedies, such as a non-judicial foreclosure with respect to any security for any portion of the Indebtedness,
destroys Pledgor’s rights of subrogation or Pledgor’s rights to proceed against Borrower for reimbursement; or (2) any loss of rights Pledgor may suffer by reason of any rights, powers or remedies of Borrower in connection with any
anti-deficiency laws or any other laws limiting, qualifying or discharging Borrower’s obligations. 
 (iii) If any of
said waivers is determined to be contrary to any applicable law or public policy, such waiver shall be effective to the extent permitted by applicable law or public policy. 

Section 18. Jurisdiction and Venue. 

(a) THE PLEDGOR IRREVOCABLY AND UNCONDITIONALLY AGREES THAT IT WILL NOT COMMENCE ANY ACTION, LITIGATION OR PROCEEDING OF ANY KIND OR
