This amendment No.1 (“Amendment No. 1”) is filed jointly by the following persons (each, a “Reporting Person” and collectively, the “Reporting Persons”): (i) Mr. Simin Zhang (“Mr. Zhang”), (ii) China Neptunus Drugstore Holding Ltd., a company incorporated under the laws of the British Virgin Islands (“Neptunus”) and (iii) New Wave Developments Limited, a company incorporated under the laws of the British Virgin Islands (“NWD”).

This Amendment No. 1 amends and supplements the Schedule 13D jointly filed by the Reporting Persons with respect to the ordinary shares, par value US$0.0001 per share (the “Ordinary Shares”), of China Nepstar Chain Drugstore Ltd., a Cayman Islands exempted company (the “Issuer”), filed with the United States Securities and Exchange Commission (the “SEC”) on July 14, 2015 (the “Original Schedule 13D”). The Issuer’s American Depositary Shares (the “ADSs”), each representing two Ordinary Shares, are listed on New York Stock Exchange under the symbol “NPD.” The Reporting Persons, however, only beneficially own the Ordinary Shares.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

Item 3 of the Original Schedule 13D is hereby amended and supplemented by inserting the following before the last paragraph:

As further described in Item 4 below, the transactions contemplated by the Merger Agreement (as defined in Item 4 below), including the Merger (as defined in Item 4 below), will be financed entirely by debt financing on the terms and conditions described in the Debt Commitment Letter (as defined in Item 4 below).

ITEM 4. PURPOSE OF TRANSACTION

Item 4 of the Original Schedule 13D is hereby amended and supplemented by inserting the following before the second to last paragraph:

Merger Agreement

On March 16, 2016, the Issuer entered into an agreement and plan of merger (the “Merger Agreement”) with Neptunus and Neptunus Global Limited (“Merger Sub”), a company incorporated under the laws of the Cayman Islands and a direct wholly-owned subsidiary of Neptunus.

The Merger Agreement provides for the merger of Merger Sub with and into the Issuer (the “Merger”), with the Issuer surviving and becoming a direct wholly-owned subsidiary of Neptunus (the “Surviving Company”). Under the terms of the Merger Agreement, at the effect time of the Merger, each ordinary share, par value US$1 per share, of Merger Sub issued and outstanding immediately prior to the effective time shall be converted into and become one validly issued, fully paid and non-assessable ordinary share, par value US$1 per share, of the Surviving Company. Such conversion shall be effected by means of the cancellation of such ordinary shares of Merger Sub, in exchange for the right to receive one such ordinary share of the Surviving Company. Such ordinary shares of the Surviving Company shall be the only issued and outstanding share capital of the Surviving Company.

Each Ordinary Share of the Issuer, including the Ordinary Shares represented by ADSs, issued and outstanding immediately prior to the effective time (excluding any Ordinary Shares beneficially owned by Neptunus, Merger Sub or their affiliates, and any dissenting shares) shall be cancelled and cease to exist in exchange for the right to receive an amount in cash equal to US$1.31 per Ordinary Share or US$2.62 per ADS without any interest thereon.

Each Ordinary Share beneficially owned (as determined pursuant to Rule 13d-3 under the Exchange Act) by Neptunus, Merger Sub or their affiliates, in each case, immediately prior to the effective time shall be cancelled and shall cease to exist as of the effective time, and no consideration or distribution shall be delivered with respect thereto.

The consummation of the Merger is subject to a number of closing conditions, including, but not limited to, approval of the Merger Agreement and the transactions (including the Merger) by the affirmative vote of holders of at least two-thirds of the Ordinary Shares present and voting at an extraordinary shareholders’ meeting of the Issuer, which is the only vote necessary to approve the Merger. The Merger Agreement may be terminated by the Issuer or Neptunus under certain circumstances.

The financing for the Merger and other transactions contemplated by the Merger Agreement will be obtained pursuant to the Debt Commitment Letter.

If the transactions contemplated by the Merger Agreement are consummated, the Surviving Company will become a privately held company beneficially owned by Mr. Simin Zhang and the ADSs will be delisted from the New York Stock Exchange and the Ordinary Shares will be deregistered under the Act. In addition, consummation of the Merger could result in one or more of the actions specified in clauses (a) - (j) of Item 4 of Schedule 13D, including the acquisition or disposition of securities of the Issuer, a merger or other extraordinary transaction involving the Issuer, a change to the board (as the surviving company in the Merger), and a change in the Issuer’s memorandum and articles of association to reflect that the Issuer would become a privately held company.

Debt Commitment Letter

In connection with the transactions contemplated by the Merger Agreement, Ping An Bank Co., Ltd. (the “Lender”) issued a debt commitment letter (the “Debt Commitment Letter”) dated March 16, 2016, which was acknowledged by Neptunus pursuant to which the Lender agreed to provide, subject to certain terms and conditions (but on a “certain funds” basis), RMB360,000,000 (or equivalent in US Dollar) of debt financing to Neptunus to consummate the Merger.

Item 4 of the Original Schedule 13D is hereby amended and supplemented by inserting the following before the last paragraph:

The description of the Merger Agreement and the Debt Commitment Letter set forth above in this Item 4 do not purport to be complete and are qualified in their entirety by reference to the full text of the Merger Agreement and the Debt Commitment Letter, which have been filed as Exhibits 7.07 and 7.08, respectively, and are incorporated herein by this reference.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

The information regarding the Merger Agreement and the Debt Commitment Letter under Item 4 is incorporated herein by reference in its entirety.
