Mr. Peng Xiaofeng is a national of the People’s Republic of China.

Pursuant to the terms set forth in (i) the schemes of arrangements under Section 86 of the Companies Law (2013 Revision) of the Cayman Islands (the “Cayman Scheme”) between and among the Company (in provisional liquidation), the Subsidiary Guarantor, and the scheme creditors therein, and (ii) the schemes of arrangement under Section 673 and 674 of the Companies Ordinance (Cap 622) of Hong Kong (the “Hong Kong Scheme”, and together with the Cayman Scheme, the “Schemes”) between the Company (in provisional liquidation), the Subsidiary Guarantor, LDK Silicon Holding Co., Limited, a Hong Kong company and a subsidiary of the Company (“LDK Silicon Hong Kong”), and the scheme creditors therein, the Company on December 17, 2014 issued 5.535% Convertible Senior Notes due 2016 (the “2016 CBs”) in exchange for a significant portion of the claims of certain creditors of the Company, the Subsidiary Guarantor, and LDK Silicon Hong Kong, primarily holders of the Subsidiary Guarantor’s series A redeemable convertible preferred shares issued in June 2011.

The 2016 CBs were issued under the Indenture to be qualified hereby, dated December 10, 2014, by and among the Company (in provisional liquidation), the Subsidiary Guarantor, The Bank of New York Mello, London Branch, as trustee, paying agent and as conversion agent, and The Bank of New York Mellon (Luxembourg) S.A., as transfer agent and as registrar, and The Bank of New York Mellon, London Branch, as collateral agent, as amended and supplemented by the first supplemental indenture, dated as of December 10, 2014, by and among the Company (in provisional liquidation), Mr. Peng Xiaofeng as additional guarantor, the Subsidiary Guarantor, The Bank of New York Mello, London Branch, as trustee, paying agent and as conversion agent, The Bank of New York Mellon (Luxembourg) S.A., as transfer agent and as registrar, and The Bank of New York Mellon, London Branch, as collateral agent (as so amended and supplemented, the “Indenture”).

When a Default is cured, it ceases to exist for all purposes under the Indenture.

One duly authorized Officer shall sign the Securities for the Company by manual or facsimile signature.

A Security’s validity shall not be affected by the failure of an Officer whose signature is on such Security to hold, at the time the Security is authenticated, the same office at the Company.

An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in the Indenture to authentication by the Trustee includes authentication by such authenticating agent. An authenticating agent so appointed has the same rights as the Trustee to deal with the Company and its Affiliates.

The Securities shall be issuable only in registered form without interest coupons and only in denominations of US$1.00 principal amount and any integral multiples of US$1.00; provided that an increase in the principal amount of Securities as a result of the Company’s election to PIK may be added, and PIK Securities may be issued, in denominations of US$1.00 in accordance with Section 2.14 of the Indenture.

There are no proceeds (and therefore no application of proceeds) from the issue of the 2016 CBs because the 2016 CBs were issued in partial satisfaction of the claims of certain creditors of the Company and its certain subsidiaries, including holders of Series A redeemable convertible preferred shares of the Subsidiary Guarantor issued in June 2011. 4.

The Trustee shall, at the request of the Company or the Guarantors upon having provided the Trustee an Officer’s Certificate and Opinion of Counsel certifying compliance with Section 11.04 of the Indenture execute and deliver a certificate to the relevant Collateral Agent directing such Collateral Agent to release the relevant Collateral or to execute such other appropriate instrument evidencing such release (in the form provided by and at the expense of the Company) upon repayment in full of the Securities.

(b) the Company or any Guarantor pays to the Trustee and the Securities Agent all other sums payable under the Indenture by the Company or the Guarantors;

(c) no Default or Event of Default with respect to the Securities shall exist on the date of such deposit;

(d) such deposit will not result in a breach or violation of, or constitute a Default or Event of Default under, the Indenture; and

(e) the Company or the Guarantors, as the case may be, shall have delivered to the Trustee and the Securities Agent an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in the Indenture relating to the satisfaction and discharge of the Indenture have been complied with;

provided, however, that Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.15, 2.16, 2.17, 4.01, 4.02, 4.07, 6.07 and 6.08 and ARTICLES VII and IX of the Indenture shall survive any discharge of the Indenture until such time as the Securities have been paid in full and there are no Securities outstanding.

9

The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year of the Company or within 14 days of a written request from the Trustee, or, if earlier, by the date the Company is, or would be, required to file with the SEC the Company’s annual report (whether on Form 20-F under the Exchange Act or another appropriate form) for such fiscal year or upon written request of the Trustee, a certificate of two or more Officers as required by TIA Section 314(a)(4) of the Indenture, stating whether or not the signatories to such certificate have actual knowledge of any Default or Event of Default by the Company in performing any of its obligations under the Indenture, the Security Documents or the Securities (without regard to any period of grace or requirement of notice under the Indenture, the Security Documents or the Securities). If such signatories do know of any such Default or Event of Default, then such certificate shall describe the Default or Event of Default and its status.

The 2016 CBs will mature on June 3, 2016; provided, however, that, at the option of the Super Majority Holders, which may be exercised one or more times, notifying the Company in writing 15 Business Days prior to the relevant Maturity Date, (i) the Maturity Date may be extended as stated in the written notice of the Super Majority Holders and/or (ii) the Company shall make the payment due on the relevant Maturity Date with Ordinary Shares or ADSs, each as provided in the Indenture.

The 2016 CBs are guaranteed by (i) the Subsidiary Guarantor, and (ii) Mr. Peng Xiaofeng.
