Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed in whole or in part without notice to or further assent from it, and that it remains bound upon its guarantee notwithstanding any such extension or renewal. All terms of this Guaranty apply to and may be enforced by any Creditor or by or on behalf of any Lending Installation of any Creditor that extended any portion of the Guaranteed Obligations.

Each Guarantor acknowledges that, without limiting the scope of the foregoing or any other provision of this Guaranty, including any provisions in the paragraph below captioned “Payments Generally,” the term “Guaranteed Obligations” includes, but is not limited to, any loss that any Creditor may incur with respect to the Guaranteed Obligations on account of prohibitions or limitations that may exist from time to time under the laws or regulations of the State Administration of Foreign Exchange (“SAFE”) or other regulatory authorities in the Peoples Republic of China (“PRC”) including with respect to the conversion into Renminbi (“RMB”) of U.S. dollars that may be paid by any Guarantor to any Creditor to satisfy any of such Guarantor’s

-2-

obligations under this Guaranty. This Guaranty is secured by all of the Collateral as more fully provided in the Security Agreement and the other applicable Loan Documents and subject to the terms and conditions therein.

3. Guaranty of Payment. This Guaranty is a guaranty of payment and not of collection. Each Guarantor waives any right to require any other guarantor of, or any other Person obligated for, all or any part of the Guaranteed Obligations (each, including each Guarantor, an “Obligated Party”), or otherwise to enforce its payment against any collateral securing all or any part of the Guaranteed Obligations. The Guaranteed Obligations shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by each Guarantor, upon (a) the acceleration of the maturity of the loans under the Credit Agreement or the SCP Loan Agreement, (b) an involuntary proceeding is commenced or an involuntary petition is filed seeking (i) liquidation, reorganization or other relief in respect of a Borrower or any Guarantor or its debts, or of a substantial part of its assets, under any federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect or (ii) the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for Borrower or any Guarantor or for a substantial part of its assets, and, in any such case, such proceeding or petition is continuing undismissed for sixty (60) days or an order or decree approving or ordering any of the foregoing is entered, (c) Borrower or any Guarantor (i) voluntarily commences any proceeding or files any petition seeking liquidation, reorganization or other relief under any federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect, (ii) consent to the institution of, or fail to contest in a timely and appropriate manner, any proceeding or petition described in clause (b) above, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for such Borrower or Guarantor for a substantial part of its assets, (iv) file an answer admitting the material allegations of a petition filed against it in any such proceeding, (v) make a general assignment for the benefit of creditors or (vi) take any action for the purpose of effecting any of the foregoing or (d) Borrower or any Guarantor become unable, admit in writing its inability, or publicly declare its intention not to, or fail generally to pay its debts as they become due, and each Creditor is free to enforce any rights or remedies it has under this Guaranty as to the Borrower or any Guarantor, and to demand payment or other performance from each Guarantor in regard to the Borrower or any Guarantor. If the Maturity Date (as defined in the Credit Agreement) has occurred or Borrowers have terminated the Commitments pursuant to Section 2.09(b) of the Credit Agreement, and in either case, Borrowers are in compliance with Section 2.09(h) of the Credit Agreement (including without limitation provision of cash collateral to secure the China Guaranty Obligations described in Section 2.09(h) of the Credit Agreement (the “Guaranty Cash Collateral”)), notwithstanding anything to the contrary in this Guaranty or any other Loan Document, the Creditors aggregate recovery under this Guaranty shall be limited to (x) an amount equal to the then outstanding Guaranty Cash Collateral plus (y) all Creditor Expenses incurred by or on behalf of any Creditor in enforcing the obligations of Guarantors under this Guaranty.

4. No Discharge or Diminishment of Guaranty.

(a) Except as otherwise provided for herein, the obligations of Guarantors hereunder are unconditional and absolute and not subject to any reduction, limitation, impairment

-3-

or termination for any reason (other than the indefeasible payment in full in cash of the Guaranteed Obligations (other than contingent obligations (excluding outstanding commitments under the SCP Facility which have not been cash collateralized pursuant to Section 2.09(h) of the Credit Agreement) for which no claim has been asserted)), including: (i) any claim of waiver, release, extension, renewal, settlement, surrender, alteration or compromise of any of the Guaranteed Obligations, by operation of law or otherwise; (ii) any change in the corporate existence, structure or ownership of Borrower or any other Obligated Party liable for any of the Guaranteed Obligations; (iii) any insolvency, bankruptcy, reorganization or other similar proceeding affecting any Obligated Party or their assets or any resulting release or discharge of any obligation of any Obligated Party; or (iv) the existence of any claim, setoff or other rights which any Guarantor may have at any time against any Obligated Party, the Creditors or any other Person, whether in connection herewith or in any unrelated transactions.

(b) The obligations of Guarantors hereunder are not subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of any of the Guaranteed Obligations or otherwise, or any provision of applicable law or regulation purporting to prohibit payment by any Obligated Party, of the Guaranteed Obligations or any part thereof.

(c) Further, the obligations of Guarantors hereunder are not discharged or impaired or otherwise affected by: (i) the failure of any Creditor to assert any claim or demand or to enforce any remedy with respect to all or any part of the Guaranteed Obligations; (ii) any waiver or modification of or supplement to any provision of any agreement relating to the Guaranteed Obligations; (iii) any release, non-perfection or invalidity of any indirect or direct security for the obligations of Borrower for all or any part of the Guaranteed Obligations or any obligations of any Obligated Party liable for any of the Guaranteed Obligations; (iv) any action or failure to act by any Creditor with respect to any collateral securing any part of the Guaranteed Obligations; or (v) any default, failure or delay, willful or otherwise, in the payment or performance of any of the Guaranteed Obligations, or any other circumstance, act, omission or delay that might in any manner or to any extent vary the risk of any Guarantor or that would otherwise operate as a discharge of any Guarantor as a matter of law or equity (other than the indefeasible payment in full in cash of the Guaranteed Obligations (other than contingent obligations (excluding outstanding commitments under the SCP Facility which have not been cash collateralized pursuant to Section 2.09(h) of the Credit Agreement) for which no claim has been asserted)).

5. Defenses Waived. To the fullest extent permitted by applicable law, each Guarantor hereby waives any defense based on or arising out of any defense of Borrower or unenforceability of all or any part of the Guaranteed Obligations from any cause, or the cessation from any cause of the liability of the Borrower, or any other Obligated Party, other than the indefeasible payment in full in cash of the Guaranteed Obligations (other than contingent obligations (excluding outstanding commitments under the SCP Facility which have not been cash collateralized pursuant to Section 2.09(h) of the Credit Agreement) for which no claim has been asserted). Without limiting the generality of the foregoing, each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and, to the fullest extent permitted by law, any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person

-4-

against any Obligated Party or any other Person. Each Guarantor confirms that it is not a surety under any state law and shall not raise any such law as a defense to its obligations hereunder. Any Creditor may, at its election, foreclose on any Collateral held by it by one or more judicial or nonjudicial sales, accept an assignment of any such Collateral in lieu of foreclosure or otherwise act or fail to act with respect to any collateral securing all or a part of the Guaranteed Obligations, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with any Obligated Party or exercise any other right or remedy available to it against any Obligated Party, without affecting or impairing in any way the liability of any Guarantor under this Guaranty except to the extent the Guaranteed Obligations (other than contingent obligations (excluding outstanding commitments under the SCP Facility which have not been cash collateralized pursuant to Section 2.09(h) of the Credit Agreement) for which no claim has been asserted) have been fully and indefeasibly paid in cash. To the fullest extent permitted by applicable law, each Guarantor waives any defense arising out of any such election even though that election may operate, pursuant to applicable law, to impair or extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against any Obligated Party or any security.

6. Rights of Subrogation. No Guarantor will assert any right, claim or cause of action, including, without limitation, a claim of subrogation, contribution or indemnification, that it has against any Obligated Party or any collateral, until Guarantors have fully performed all its obligations to the Creditors.

7. Reinstatement; Stay of Acceleration. If at any time any payment of any portion of the Guaranteed Obligations (including a payment effected through exercise of a right of setoff) is rescinded, or must otherwise be restored or returned upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise (including pursuant to any settlement entered into by any Creditor in its discretion), each Guarantor’s obligations under this Guaranty and any provision of any Loan Document or the SCP Facility with respect to that payment shall be reinstated at such time as though the payment had not been made and whether or not any Creditor is in possession of this Guaranty. If acceleration of the time for payment of any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of the Borrower, all such amounts otherwise subject to acceleration under the terms of any agreement relating to the Guaranteed Obligations shall nonetheless be payable by the Guarantors forthwith on demand by any Creditor.

8. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of the Borrower’s’ financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs under this Guaranty, and agrees that no Creditor shall have any duty to advise any Guarantor of information known to it regarding those circumstances or risks.

9. Termination Any Creditor may continue to make loans or extend credit to the Borrower based on this Guaranty until five (5) days after it receives written notice of termination from each Guarantor. Notwithstanding receipt of any such notice, each Guarantor will continue to be liable to Creditors for any Guaranteed Obligations created, assumed or committed to prior to the fifth day after receipt of the notice, and all subsequent renewals, extensions, modifications and amendments with respect to, or substitutions for, all or any part of such Guaranteed Obligations.

-5-

10. Taxes. Each payment of the Guaranteed Obligations will be made by each Guarantor without withholding for any Taxes, unless such withholding is required by law. If any Guarantor determines, in its sole discretion exercised in good faith, that it is so required to withhold Taxes, then such Guarantor may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by the applicable Guarantor shall be increased as necessary so that, net of such withholding (including such withholding applicable to additional amounts payable under this Section 10), an applicable Creditor receives the amount it would have received had no such withholding been made.

11. Maximum Liability. Notwithstanding any other provision of this Guaranty, the amount guaranteed by any Guarantor hereunder shall be limited to the extent, if any, required so that its obligations hereunder shall not be subject to avoidance under Section 548 of the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law. In determining the limitations, if any, on the amount of any Guarantor’s obligations hereunder pursuant to the preceding sentence, it is the intention of the parties hereto that any rights of subrogation, indemnification or contribution which any Guarantor may have under this Guaranty, any other agreement or applicable law shall be taken into account.

12. Contribution.

(a) To the extent that a Guarantor shall make a payment under this Guaranty which, taking into account all other payments then previously or concurrently made by any other guarantor of the Guaranteed Obligations (any such payment, a “Guarantor Payment”), exceeds the amount which otherwise would have been paid by or attributable to such Guarantor if such other guarantor had paid the aggregate Guaranteed Obligations satisfied by such Guarantor Payment in the same proportion as such Guarantor’s “Allocable Amount” (as defined below) (as determined immediately prior to such Guarantor Payment) bore to the aggregate Allocable Amounts of each of the guarantors as determined immediately prior to the making of such Guarantor Payment, then, following indefeasible payment in full in cash of the Guarantor Payment and the Guaranteed Obligations (other than contingent obligations (excluding outstanding commitments under the SCP Facility which have not been cash collateralized pursuant to Section 2.09(h) of the Credit Agreement) for which no claim has been asserted), each Guarantor shall be entitled to receive contribution and indemnification payments from, and be reimbursed by, each other guarantor of the Guaranteed Obligations for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment.

(b) As of any date of determination, the “Allocable Amount” of any guarantor of the Guaranteed Obligations shall be equal to the excess of the fair saleable value of the property of such guarantor over the total liabilities of such guarantor (including the maximum amount reasonably expected to become due in respect of contingent liabilities, calculated, without duplication, assuming each other guarantor that is also liable for such contingent liability pays its ratable share thereof), giving effect to all payments made by other guarantors as of such date in a manner to maximize the amount of such contributions.

-6-

(c) This Section 12 is intended only to define the relative rights of the guarantors of the Guaranteed Obligations, and nothing set forth in this Section 12 is intended to or shall impair the obligations of the guarantors, jointly and severally, to pay any amounts as and when the same shall become due and payable in accordance with the terms of their applicable guaranty of the Guaranteed Obligations.

(d) The parties hereto acknowledge that the rights of contribution and indemnification hereunder shall constitute assets of the guarantor or guarantors to which such contribution and indemnification is owing.

(e) The rights of the indemnifying guarantors against other guarantors under this Section 12 shall be exercisable upon the full and indefeasible payment of the Guaranteed Obligations in cash (other than contingent obligations (excluding outstanding commitments under the SCP Facility which have not been cash collateralized pursuant to Section 2.09(h) of the Credit Agreement) for which no claim has been asserted).

13. Liability Cumulative. The liability of each Guarantor under this Guaranty is in addition to and shall be cumulative with all liabilities of each Loan Party to any Creditor under this Guaranty and the other Loan Documents to which any Guarantor is a party or any other document, instrument or agreement with any Creditor to which any Guarantor is a party, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

14. Keepwell. Each Qualified ECP Guarantor hereby absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under this Guarantee in respect of a Swap Obligation (provided, however, that the Qualified ECP Guarantor shall only be liable under this Section 14 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 14 or otherwise under this Guaranty voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). Except as otherwise provided herein, the obligations of the Qualified ECP Guarantor under this Section 14 shall remain in full force and effect until the termination of all Swap Obligations. The Qualified ECP Guarantor intends that this Section 14 constitute, and this Section 14 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

15. Representations and Warranties. Each Guarantor represents and warrants to each Creditor that:

(a) Authorization; Enforceability.

16. Modification. The terms of this Guaranty may be waived, discharged, or terminated only by an instrument in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought.

21. Lending Installations. JPMC may designate, in its sole discretion, one or more of its and/or JPMorgan Chase & Co.’s offices, branches, facilities, parent company(ies), subsidiaries or affiliates (each, including JPMC, a “Lending Installation”) that is or are to make and book any of the Guaranteed Obligations or hold any security interests with respect thereto on behalf of any Lending Installation and for whose account payments are to be made, and may change any of them from time to time, and each Guarantor, JPMC and each Lending Installation agrees and consents thereto. JPMC shall endeavor to provide the Guarantors written notice of any new Lending Installation hereunder but the failure to provide such notice shall not cause such entity to fail to be a Lending Installation hereunder; provided however, that JPMC shall provide written notice to Guarantors of all Lending Installations holding Guaranteed Obligations or any security interests with respect thereto promptly after the occurrence of any enforcement of this Guaranty by JPMC or any Creditor. Each Guarantor, JPMC and each Lending Installation agrees that all terms of this Guaranty and any documents, instruments or agreements related thereto (including without limitation the Security Agreement) shall apply to, be for the benefit of, and be enforced by or on behalf of JPMC, any Lending Installation or their successors and assigns. For the avoidance of doubt, without limiting the scope of the foregoing, the term “Lending Installation” includes, but is not limited to, the JPMC Chinese Affiliate.

22. Payments Generally.

(a) All payments by Guarantors shall be made in the manner, at the place and in the currency (the “Payment Currency”) required by the SCP Loan Agreement or SCP Loan Facility; provided, however, that (if the Payment Currency is other than U.S. dollars) a Guarantor may, at its option (or, if for any reason whatsoever a Guarantor is unable to effect payments in the foregoing manner, such Guarantor shall be obligated to) pay to JPMC at its principal office the equivalent amount in U.S. dollars computed at the selling rate of JPMC or a selling rate chosen by JPMC, most recently in effect on or prior to the date the Guaranteed Obligations becomes due, for cable transfers of the Payment Currency to the place where the Guaranteed Obligations is payable. In any case in which any Guarantor makes or is obligated to make payment in U.S. dollars, Guarantors shall hold each Creditor harmless from any loss incurred by such Creditor arising from any change in the value of U.S. dollars in relation to the Payment Currency between the date the Guaranteed Obligations becomes due and the date such Creditor is actually able, following the conversion of the U.S. dollars paid by Guarantors into the Payment Currency and remittance of such Payment Currency to the place where such Guaranteed Obligations is payable, to apply such Payment Currency to such Guaranteed Obligations.

(b) Without limiting the scope of the preceding paragraph, if for the purposes of obtaining judgment in any court it is necessary to convert a sum due from any Guarantor under this Guaranty in a Payment Currency (the “specified currency”) into another currency, each

-10-

Guarantor agrees, to the fullest extent that it may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, JPMC could purchase the specified currency with such other currency at an office of JPMC chosen by JPMC in its sole discretion on the Business Day preceding that on which a final, non-appealable judgment is given. The obligations of Guarantors in respect of any sum due to any Creditor shall, notwithstanding any judgment in a currency other than the specified currency, be discharged only to the extent that on the business day following receipt by such Creditor of any sum adjudged to be so due in such other currency such Creditor may in accordance with normal, reasonable banking procedures purchase the specified currency with such other currency. If the amount of the specified currency so purchased is less than the sum originally due to the applicable Creditor in the specified currency, each Guarantor agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Creditor against such loss.

23. Warranty and Covenant Re PRC SAFE Regulation.

(a) Each Guarantor agrees (i) to comply with, and (with respect to Sagent) to cause the Borrower to comply with, all laws, regulations and rules of SAFE or other governmental authorities in the PRC; and (ii) to do all acts necessary, and (with respect to Sagent) to cause the Borrower to do all acts necessary, so as to permit an applicable Creditor, to convert into RMB all amounts that may be paid to such Creditor to satisfy any Guarantor’s obligations under this Guaranty, including, without limitation, maintaining a sufficient net asset value of the Borrower as indicated in its audited financial statements of the immediately preceding financial year and/or “Borrowing Gap” (as defined below) available for the enforcement of this Guaranty.

(b) For the purpose of the preceding paragraph, the term “Borrowing Gap” with respect to the Borrower means the concept of “borrowing gap” as provided under relevant PRC laws, regulations and rules, as amended from time to time. Each Guarantor understands that such concept may change from time to time and has obtained all necessary independent professional advice as it considers appropriate.

(c) Nothing in the foregoing shall be construed as modifying, limiting, conditioning, or otherwise derogating either from any rights or remedies that any Creditor otherwise has or may have under this Guaranty or from any obligations or liabilities any Guarantor otherwise has or may have under this Guaranty in regard to the Borrower.

24. APPLICABLE LAW. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE OF ILLINOIS (INCLUDING, WITHOUT LIMITATION, 735 ILCS SECTION 105/5-1 ET SEQ), BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

25. CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

(a) EACH GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE EXCLUSIVE JURISDICTION OF ANY U.S. FEDERAL OR ILLINOIS STATE COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF
