SUPPLEMENTAL AGREEMENT

THIS SUPPLEMENTAL AGREEMENT (the “Agreement”) is entered as of the 4th day of June, 2009, by and between Renewable Fuel Corp, a Nevada corporation (“RFC”) and Oilcorp International Limited (“Oilcorp”).  Each of RFC and Oilcorp may be referred to herein as a “Party” and collectively as the “Parties.”

A.           RFC and Oilcorp have previously entered into a subscription agreement (the “Prior Agreement”) which included a term sheet (the “Prior Term Sheet”) relating to the sale by RFC and the purchase by Oilcorp of certain shares of RFC’s Series A Convertible Preferred Stock (the “Preferred Stock”).

B.           The Prior Term Sheet set forth certain terms and conditions relating to the purchase of the Preferred Stock, conversion of the Preferred Stock by Oilcorp, conditions to the purchase, and other terms.

C.           The Parties now desire to amend and supplement certain terms and conditions relating to the Preferred Stock as set forth below.

NOW THEREFORE, based on the foregoing recitals and for and in consideration of the mutual covenants and agreements hereinafter set forth and the mutual benefits to RFC and Oilcorp, to be derived herefrom, and intending to be legally bound hereby, RFC and Oilcorp hereby agree as follows:

1.             Conversion of Preferred Stock; Issuance of Warrants.  In addition to the provisions relating to the conversion (both automatic conversion and optional conversion) as set forth in the Prior Term Sheet, the following conditions and terms shall apply to the Preferred Stock:

a.

Assuming the conditions to closing set forth in the Prior Term Sheet are met, Oilcorp shall own 2,211,166 shares of Preferred Stock at closing.

b.

The per share Conversion Price of the Preferred Stock is US$1 per share.  Accordingly, upon conversion of the shares of Preferred Stock, Oilcorp will hold 22,111,664 shares of common stock of RFC.

c.

As of the date of this Agreement, RFC was preparing to file a registration statement (the “Registration Statement”) with the U.S. Securities and Exchange Commission (“SEC”) to register the shares of RFC’s common stock with the SEC to enable RFC to become a public company.

d.

Following the declaration of effectiveness of the Registration Statement by the SEC, RFC shall seek to have its shares begin trading on a stock exchange, market, or other trading facility.

e.

Following the commencement of trading of RFC’s common stock on a stock exchange, market, or other trading facility, RFC shall calculate the ten-day weighted average price of the common stock (the “WAP”) for the first ten (10) days of trading.

f.

If the WAP when calculated is less than US$1.00 per share, RFC shall issue to Oilcorp, warrants (the “Oilcorp Warrants”), in substantially the form as set forth in Appendix A hereto exercisable for a term of thirty-six (36) month from the date of issuance, to purchase additional shares of RFC’s common stock as follows:

i.

The Oilcorp Warrants shall have an exercise price (the “Exercise Price”) of $0.10 per share. As noted, the Warrants shall be exercisable for the period of thirty-six (36) months,

ii.

The number of Oilcorp Warrants to be issued shall be determined as follows:

a)

The adjusted weighted average price (the “AWAP”) shall be equal to the WAP minus a discount of ten percent (10%) of the WAP.

b)           The Theoretical Value of the Warrants (“TVW”) shall be equal to the AWAP minus $0.10 (the Exercise Price).

c)           The shortfall amount owed (the “Shortfall”) shall be determined by multiplying the dollar value of all unconverted shares of Preferred Stock, plus any accrued but unpaid interest (the “Aggregate Value”) by the WAP to determine the trading value (the “Trading Value”), and then subtracting the Trading Value from the Aggregate Value.

d)           Then, the Shortfall divided by the TVW shall equal the number of Oilcorp Warrants to be issued.

WAP - 10% = AWAP

AWAP - $0.10 (Exercise Price) = TVW

Aggregate Value x WAP = Trading Value

Aggregate Value - Trading Value = Shortfall

Shortfall / TVW = Number of Oilcorp Warrants to issue.

$0.90 (WAP) - 10% = $0.81 (AWAP)

$0.81 (AWAP) - $0.10 (Exercise Price) = $0.71 (TVW)

$22,111,664 (Aggregate Value) x $0.90 (WAP) = $19,900,498 Trading Value

$22,111,664 (Aggregate Value) - $19,900,498 (Trading Value) = $2,211,166 (Shortfall)

$2,211,166 (Shortfall) / $0.71 (TVW) = 3,114,318 Oilcorp Warrants to issue.

g.

If the WAP when calculated is equal to or more than US$1.00 per share, RFC shall have no obligation to issue any Oilcorp Warrants.

2.             Dividend on Preferred Stock.

a.

The Preferred Stocks held by Oilcorp will carry cumulative dividend of 8%, which shall begin to accrue as soon as all of the conditions to closing set forth in the Prior Term Sheet have been met and satisfied to the satisfaction of both Parties.  RFC shall have the option, in its sole discretion, to pay any accrued dividends in cash or additional warrants (the “Dividend Warrants”).

b.

If RFC chooses to pay any dividends through the issuance of Dividend Warrants, the number of Dividend Warrants shall be calculated by dividing the dividend amount by the TVW (as calculated pursuant to Paragraph 1).

3.             Renewal of Representations and Warranties.  In the event that RFC issues the Oilcorp Warrants and/or the Dividend Warrants, as a further condition to receiving the Oilcorp Warrants or the Dividend Warrants, Oilcorp agrees to provide to RFC a Confidential Investor Questionnaire, similar in terms and content to that given in connection with the Prior Agreement, making the applicable representations about Oilcorp’s status as an Accredited Investor and other representations as contained in the Confidential Investor Questionnaire.

4.             Affirmation of Prior Agreement.  Unless specifically revised by this Agreement, all terms, conditions, and provisions of the Prior Agreement, including those in the Prior Term Sheet, the prior Subscription Agreement, and the prior Confidential Investor Questionnaire are hereby affirmed and agreed to, and such terms, conditions, and provisions shall continue in full force as set forth in the Prior Agreement.

(a)           If the Company, at any time while this Warrant is outstanding, (i) shall pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock (as defined below) or on any other class of capital stock (and not the Common Stock) payable in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock into a larger number of shares, or (iii) combine outstanding shares of Common Stock into a smaller number of shares, the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding after such event.  Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of  a subdivision or combination, and shall apply to successive subdivisions and combinations.

(d)           If, at any time while this Warrant is outstanding, the Company shall issue or cause to be issued rights or warrants to acquire or otherwise sell or distribute shares of Common Stock to all holders of Common Stock for a consideration per share less than the Exercise Price then in effect, then, forthwith upon such issue or sale, the Exercise Price shall be reduced to the price (calculated to the nearest cent) determined by dividing (i) an amount equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to such issue or sale multiplied by the Exercise Price, and (B) the consideration, if any, received or receivable by the Company upon such issue or sale by (ii) the total number of shares of Common Stock outstanding immediately after such issue or sale.

(e)           For the purposes of this Section 8, the following clauses shall also be applicable:

(i)  Record Date.  In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock or in securities convertible or exchangeable into shares of Common Stock, or (B) to subscribe for or purchase Common Stock or securities convertible or exchangeable into shares of Common Stock, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.
