Date of Issuance: September 28, 2010

FOR VALUE RECEIVED, the undersigned, Keyuan Petrochemicals, Inc., a Nevada corporation (together with its successors and assigns, the “ Issuer ” or the “ Company ” ), hereby certifies that [                  ] or its registered assigns is entitled to subscribe for and purchase, during the Term (as hereinafter defined), up to [__________________________] ([_______]) shares (subject to adjustment as hereinafter provided) of the duly authorized, validly issued, fully paid and non-assessable Common Stock of the Issuer, at an exercise price per share equal to the Warrant Price then in effect, subject, however, to the provisions and upon the terms and conditions hereinafter set forth. Capitalized terms used in this Warrant and not otherwise defined herein shall have the respective meanings specified in Section 7 hereof.

1.            Term . The term of this Warrant shall commence on September [ ], 2010 and shall expire at 6:00 p.m., Eastern Time, on September 28, 2013 (such period being the “ Term ” ).

(a)            Time of Exercise . The purchase rights represented by this Warrant may be exercised in whole or in part during the Term.

(b)            Method of Exercise . The Holder hereof may exercise this Warrant, in whole or in part, by delivery to the Issuer (or such other office or agency of the Issuer as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Issuers) of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto (“Notice of Exercise Form”); and, within three (3) Trading Days of the date said Notice of Exercise Form is delivered to the Issuer, the Issuer shall have received payment of an amount of consideration therefor equal to the Warrant Price in effect on the date of such exercise multiplied by the number of shares of Warrant Stock with respect to which this Warrant is then being exercised, payable at such Holder’s election (i) by certified or official bank check or by wire transfer to an account designated by the Issuer, (ii) by “cashless exercise” in accordance with the provisions of subsection (c) of this Section 2 , but only when a registration statement under the Securities Act providing for the resale of the Warrant Stock and the Common Stock underlying the preferred stock issued pursuant to the Purchase Agreement is not then in effect as required under the Registration Rights Agreement (as defined below), or (iii) by a combination of the foregoing methods of payment selected by the Holder of this Warrant. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant, or an indemnification reasonably acceptable to the Issuer undertaking with respect to such Warrant in the case of its loss, theft or destruction, to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise Form is delivered to the Company.  Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased.  The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases.  Subject to all rights of the Holder herein, the Company shall deliver any objection to any Notice of Exercise Form within one (1) Business Day of receipt of such notice and such objection shall contain the reason for such objection along with documentation supporting the Company’s reason for objecting.  In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error.

(c)            Cashless Exercise . Notwithstanding any provision herein to the contrary, but subject to Section 2(b)(ii) hereof, and commencing twelve (12) months following the Original Issue Date, if the Per Share Market Value of one share of Common Stock is greater than the Warrant Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of cash, the Holder may exercise this Warrant by a cashless exercise (“ Cashless Exercise ” ) by surrender of this Warrant at the principal office of the Issuer together with the properly endorsed Notice of Exercise, in which event the Issuer shall issue to the Holder a number of shares of Common Stock computed using the following formula:

X = Y - (A)(Y)

             B

If at any time after the effective date of the registration statement, there is not an effective registration statement covering the resale of the shares underlying the Warrant, the Holder may exercise this Warrant by Cashless Exercise; provided, however , that the Holder may not exercise this Warrant by Cashless Exercise if at any time the registration statement is not effective for any of the reasons set forth in Section 3(n) of the Registration Rights Agreement (as defined in the Purchase Agreement).

(d)            Issuance of Stock Certificates . In the event of any exercise of this Warrant in accordance with and subject to the terms and conditions hereof, certificates for the shares of Warrant Stock so purchased shall be dated the date of such exercise and delivered to the Holder’s Prime Broker as specified in the Holder’s exercise form within a reasonable time, not exceeding five (5) Trading Days after such exercise (the “ Delivery Date ”) or, at the request of the Holder (provided that a registration statement under the Securities Act providing for the resale of the Warrant Stock is then in effect or that the shares of Warrant Stock are otherwise exempt from registration), issued and delivered to the Depository Trust Company (“ DTC ”) account on the Holder’s behalf via the Deposit Withdrawal Agent Commission System (“ DWAC ”) within a reasonable time, not exceeding five (5) Trading Days after such exercise, and the Holder hereof shall be deemed for all purposes to be the holder of the shares of Warrant Stock so purchased as of the date of such exercise. Notwithstanding the foregoing to the contrary, the Issuer or its transfer agent shall only be obligated to issue and deliver the shares to the DTC on a holder’s behalf via DWAC if such exercise is in connection with a sale in reliance upon an effective Registration Statement or other exemption from registration by which the shares may be issued without a restrictive legend and the Issuer and its transfer agent are participating in DTC through the DWAC system.

(e)            Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise . In addition to any other rights available to the Holder, if the Issuer fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the Warrant Stock pursuant to an exercise on or before the second business day following the Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Stock which the Holder anticipated receiving upon such exercise (a “ Buy-In ”), then the Issuer shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of shares of Warrant Stock that the Issuer was required to deliver to the Holder in connection with the exercise at issue times (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of shares of Warrant Stock for which such exercise was not honored or deliver to the Holder the number of shares of Common Stock that would have been issued had the Issuer timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Issuer shall be required to pay the Holder $1,000. The Holder shall provide the Issuer written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Issuer. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Issuer’s failure to timely deliver certificates representing shares of Common Stock upon exercise of this Warrant as required pursuant to the terms hereof.

(f)            Transferability of Warrant . Subject to Section 2(h) hereof, this Warrant may be transferred by a Holder, in whole or in part, without the consent of the Issuer. If transferred pursuant to this paragraph, this Warrant may be transferred on the books of the Issuer by the Holder upon surrender of this Warrant at the principal office of the Issuer or is designated agent, properly endorsed (by the Holder executing an assignment in the form attached hereto) and upon payment of any necessary transfer tax or other governmental charge imposed upon such transfer. This Warrant is exchangeable for Warrants to purchase the same aggregate number of shares of Warrant Stock, each new Warrant to represent the right to purchase such number of shares of Warrant Stock as the Holder hereof shall designate at the time of such exchange. All Warrants issued on transfers or exchanges shall be dated the Original Issue Date and shall be identical with this Warrant except as to the number of shares of Warrant Stock issuable pursuant thereto.

(g)            Continuing Rights of Holder . The Issuer shall, at the time of or at any time after each exercise of this Warrant, upon the request of the Holder hereof, acknowledge in writing the extent, if any, of its continuing obligation to afford to such Holder all rights to which such Holder shall continue to be entitled after such exercise in accordance with the terms of this Warrant, provided that if any such Holder shall fail to make any such request, the failure shall not affect the continuing obligation of the Issuer to afford such rights to such Holder.

(h)            Compliance with Securities Laws.

(i)           The Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant and the shares of Warrant Stock to be issued upon exercise hereof are being acquired solely for the Holder’s own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any shares of Warrant Stock to be issued upon exercise hereof except pursuant to an effective registration statement, or an exemption from registration, under the Securities Act and any applicable state securities laws.

(ii)           Except as provided in paragraph (iii) below, this Warrant and all certificates representing shares of Warrant Stock issued upon exercise hereof shall be stamped or imprinted with a legend in substantially the following form:

THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ SECURITIES ACT ”), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

(iii)           The Issuer agrees to reissue this Warrant or certificates representing any of the Warrant Stock, without the legend set forth above, if at such time, prior to making any transfer of any such securities, the Holder shall give written notice to the Issuer describing the manner and terms of such transfer and demonstrating that the following conditions are satisfied. Such proposed transfer will not be effected until: (a) either (i) the Issuer has received an opinion of counsel reasonably satisfactory to the Issuer, to the effect that the registration of such securities under the Securities Act is not required in connection with such proposed transfer, (ii) a registration statement under the Securities Act covering such proposed disposition has been filed by the Issuer with the Securities and Exchange Commission and has become and remains effective under the Securities Act, (iii) the Issuer has received other evidence reasonably satisfactory to the Issuer that such registration and qualification under the Securities Act and state securities laws are not required, or (iv) the holder provides the Issuer with reasonable assurances that such security can be sold pursuant to Rule 144(i) under the Securities Act, and (b) either (i) the Issuer has received an opinion of counsel reasonably satisfactory to the Issuer, to the effect that registration or qualification under the securities or “blue sky” laws of any state is not required in connection with such proposed disposition, or (ii) compliance with applicable state securities or “blue sky” laws has been effected or a valid exemption exists with respect thereto. The Issuer shall respond to any such notice from a holder within five (5) Trading Days. In the case of any proposed transfer under this Section 2(h) , the Issuer shall use reasonable efforts to comply with any such applicable state securities or “blue sky” laws, but shall in no event be required, (x) to qualify to do business in any state where it is not then qualified, (y) to take any action that would subject it to tax or to the general service of process in any state where it is not then subject, or (z) to comply with state securities or “blue sky” laws of any state for which registration by coordination is unavailable to the Issuer. Whenever a certificate representing the Warrant Stock is required to be issued to the Holder without a legend, in lieu of delivering physical certificates representing the Warrant Stock, the Issuer shall cause its transfer agent to electronically transmit the Warrant Stock to the Holder by crediting the account of the Holder or Holder’s Prime Broker with DTC through its DWAC system (to the extent not inconsistent with any provisions of this Warrant or the Purchase Agreement).

(i)            Accredited Investor Status . At the time of the exercise of this Warrant, the Holder (1) shall be an “accredited investor” as defined in Regulation D under the Securities Act, (2) exempt from registration pursuant to Regulation S, or (3) shall exercise this Warrant by means of a Cashless Exercise as provided for in Section 2(c) , subject to any applicable restrictions.

3.            Adjustment of Warrant Price . The Warrant Price shall be subject to adjustment from time to time as set forth in this Section 3 . The Issuer shall give the Holder written notice of any event described below which requires an adjustment pursuant to this Section 3 in accordance with the notice provisions set forth in Section 12 .

(a)            Adjustments for Stock Splits, Combinations, Certain Dividends and Distributions .  If the Issuer shall, at any time or from time to time after the Original Issue Date, effect a split of the outstanding Common Stock (or any other subdivision of its shares of Common Stock into a larger number of shares of Common Stock), combine the outstanding shares of Common Stock into a smaller number of shares of Common Stock, or make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in shares of Common Stock, then, in each event (i) the number of shares of Common Stock for which this Warrant shall be exercisable immediately after the occurrence of any such event shall be adjusted to equal the number of shares of Common Stock that a record holder of the same number of shares of Common Stock for which this Warrant is exercisable immediately prior to the occurrence of such event would own or be entitled to receive after the happening of such event, and (ii) the Warrant Price then in effect shall be adjusted to equal (A) the Warrant Price then in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment.

(b)            Adjustment for Other Dividends and Distributions . If the Issuer shall, at any time or from time to time after the Original Issue Date, make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in (i) cash, (ii) any evidences of indebtedness, or any other securities of the Company or any property of any nature whatsoever, other than, in each case, shares of Common Stock; or (iii) any warrants or other rights to subscribe for or purchase any evidences of indebtedness, or any other securities of the Company or any property of any nature whatsoever, other than, in each case, shares of Common Stock, then, and in each event, (A) the number of shares of Common Stock for which this Warrant shall be exercisable shall be adjusted to equal the product of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such adjustment multiplied by a fraction (1) the numerator of which shall be the Per Share Market Value of Common Stock at the date of taking such record and (2) the denominator of which shall be such Per Share Market Value minus the amount allocable to one share of Common Stock of any such cash so distributable and of the fair value (as determined in good faith by the Board and supported by an opinion from an investment banking firm mutually agreed upon by the Issuer and the Holder) of any and all such evidences of indebtedness, shares of stock, other securities or property or warrants or other subscription or purchase rights so distributable, and (B) the Warrant Price then in effect shall be adjusted to equal (1) the Warrant Price then in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior to the adjustment divided by (2) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment. A reclassification of the Common Stock (other than a change in par value, or from par value to no par value or from no par value to par value) into shares of Common Stock and shares of any other class of stock shall be deemed a distribution by the Issuer to the holders of its Common Stock of such shares of such other class of stock within the meaning of this Section 3(b) and, if the outstanding shares of Common Stock shall be changed into a larger or smaller number of shares of Common Stock as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock within the meaning of Section 3(a) .

(c)           ­ Adjustments for Reclassification, Exchange or Substitution . If the Common Stock for which this Warrant is exercisable at any time or from time to time after the Original Issue Date shall be changed to the same or different number of shares of any class or classes of stock, whether by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination of shares or stock dividends provided for in Section 3(a) , Section 3(b) , or a reorganization, merger, consolidation, or sale of assets provided for in Section 3(d) ), then, and in each event, an appropriate revision to the Warrant Price shall be made and provisions shall be made (by adjustments of the Warrant Price or otherwise) so that, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, in lieu of Warrant Stock, the kind and amount of shares of stock and other securities receivab
