ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

The shares of Common Stock currently held by the Reporting Persons (whether purchased on the NASDAQ Global Market or through the exercise of incentive stock options and/or non-qualified stock options granted to the Reporting Persons in the course of their employment with MEMSIC) have been acquired using the personal funds of each individual Reporting Person. Shares acquired by the Reporting Persons through the vesting of restricted stock units or grants of restricted stock were acquired without payment of consideration (other than continued employment with MEMSIC).

Pursuant to the terms of the Merger Agreement, at the effective time of the merger, each option to purchase shares of Common Stock granted by the Company, including those held by the Rollover Holders, will be cancelled, and any such options that are “in-the-money” at the effective time of the merger shall be converted into the right to receive cash in an amount equal to: (i) the total number of shares of Common Stock subject to such option immediately prior to the consummation of the merger (without regard to vesting), multiplied by (ii) the excess, if any, of the $4.225 per share merger consideration over the exercise price per share of Common Stock subject to such option, less (iii) any amounts that are required to be withheld or deducted under applicable tax provisions. Such amount will be paid as soon as reasonably practicable after the consummation of the merger. The Reporting Persons presently do not contemplate contributing any Common Stock subject to such options to Parent under the terms of the Contribution Agreement in exchange for equity securities of Parent.

Pursuant to the terms of the Merger Agreement, at the effective time of the merger, each restricted stock award and each restricted stock unit granted by the Company, including those held by the Rollover Holders, will be cancelled and converted into the right to receive the $4.225 per share merger consideration. Such amounts will be paid as soon as reasonably practicable after the consummation of the merger. The Reporting Persons presently do not contemplate contributing any Common Stock subject to restricted stock awards or restricted stock units under the terms of the Contribution Agreement in exchange for equity securities of Parent.

Pursuant to the terms of the Contribution Agreement, the Sponsor will purchase, for a per share consideration equal to the merger consideration under the Merger Agreement, any outstanding shares of Common Stock beneficially held by the Rollover Holders that are not exchanged for newly issued shares of Parent.

The Reporting Persons anticipate that, at the time they contribute their Common Stock and/or cash consideration to Parent in exchange for equity securities of Parent pursuant to the terms of the Contribution Agreement, any cash consideration needed shall be funded from either such Reporting Persons’ personal funds or the cash proceeds available to any Rollover Holder, including the Reporting Persons, pursuant to the Contribution Agreement or the Merger Agreement. Any cash consideration contributed by the Rollover Holders in exchange for equity securities of Parent must be deposited with Parent at least seven (7) days before the anticipated effective time of the merger. The Rollover Holders may satisfy this obligation by giving irrevocable instructions to: (i) Sponsor to pay over to Parent any portion of any amount owed by Sponsor to a Rollover Holder for the purchase of such Rollover Holder’s shares of Common Stock pursuant to the terms of the Contribution Agreement, and/or (ii) MEMSIC to pay over to Parent any portion of any cash to be received by such Rollover Holders in exchange for stock options, restricted stock awards and/or restricted stock units pursuant to the terms of the Merger Agreement.

The descriptions of the Equity Commitment Letter and Limited Guaranty (as such terms are defined below) in Item 6 of this Schedule are incorporated herein by reference.

ITEM 4. PURPOSE OF TRANSACTION.

On April 22, 2013, the Company, Parent and Merger Sub entered into the Merger Agreement. Pursuant to the Merger Agreement, Merger Sub will be merged with and into MEMSIC, with MEMSIC as the surviving corporation. Parent and Merger Sub are affiliates of Sponsor. Under the terms of the Merger Agreement, each share of Common Stock issued and outstanding immediately prior to the effective time of the merger will be cancelled in exchange for the right to receive US$4.225 in cash, without interest, except shares held by MEMSIC as treasury stock or otherwise owned by Parent, Merger Sub or any wholly owned subsidiary of MEMSIC, dissenting shares, and shares that may be contributed by the Reporting Persons and other Rollover Holders to Parent prior to the effective time of the Merger (pursuant to the Contribution Agreement).

On April 23, 2013, MEMSIC announced the merger in a press release, and furnished to the SEC a current report on Form 8-K regarding the merger.

The purpose of the transactions contemplated under the Merger Agreement (including the merger) and the Contribution Agreement is to allow Sponsor and the IDG Funds to acquire all of the publicly held shares of the Common Stock that they do not already own, while simultaneously allowing the Reporting Persons to maintain an indirect equity interest in MEMSIC. If the merger is consummated, the Common Stock would become eligible for termination of registration pursuant to Section 12(g)(4) of the Act and would be delisted from the NASDAQ Global Market, allowing the Company to become privately beneficially held by Parent. In turn, Parent would be wholly owned by the Rollover Holders, including the Reporting Persons, subject to the terms and conditions of the Contribution Agreement. Pursuant to the terms of the Merger Agreement, the directors of Merger Sub would become the directors of the Company, and the certificate of incorporation and bylaws of Merger Sub would become the certificate of incorporation and bylaws of the Company (except with respect to the name of the Company). The information disclosed in this Item 4 is qualified in its entirety by reference to the Merger Agreement and the Contribution Agreement, which are incorporated herein by reference in their entirety.

Except as described in Items 3, 4 and 6 of this Schedule, none of the Reporting Persons nor, to the best knowledge of the Reporting Persons, Sponsor and the IDG Funds, has any plans or proposals which relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, formulate other purposes, plans or proposals regarding MEMSIC, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

(a) – (b)

The Reporting Persons may be deemed to beneficially own, in the aggregate, 1,960,221 shares of Common Stock, representing approximately 7.7% of MEMSIC’s outstanding Common Stock (based upon 24,288,854 shares of Common Stock outstanding as of April 26, 2013, as reported by MEMSIC in its Form 10-K/A filed on April 30, 2013, and assuming the Reporting Persons’ acquisition of 1,273,825 shares of Common Stock subject to incentive stock options, non-qualified stock options and restricted stock units held by such Reporting Persons). The Rollover Holders may be deemed to beneficially own, in the aggregate, 6,685,444 shares of Common Stock, representing approximately 26.1% of MEMSIC’s outstanding Common Stock (based upon 24,288,854 shares of Common Stock outstanding as of April 26, 2013, as reported by MEMSIC in its Form 10-K/A filed on April 30, 2013, and assuming the Reporting Persons’ acquisition of 1,273,825 shares of Common Stock subject to incentive stock options, non-qualified stock options and restricted stock units held by the Rollover Holders).

Each Reporting Person has sole voting power and sole dispositive power over the shares of Common Stock beneficially owned by such Reporting Person. The responses of the Reporting Persons to Rows (7) through (11) of the cover pages of this Schedule are incorporated herein by reference.

Notwithstanding the foregoing, Dr. Zhao disclaims beneficial ownership of the 18,596 shares of Common Stock held as Trustee of the Yang Zhao Children’s Grantor Retained Annuity Trust, except to the extent of his pecuniary interest therein. Except as expressly otherwise set forth in this Schedule, each Reporting Person disclaims beneficial ownership of the shares of Common Stock beneficially owned by any other Reporting Person, Rollover Holder, or other person.

(c)

Except: (i) as set forth in Items 3, 4 and 6 of this Schedule, incorporated herein by reference, and (ii) Dr. Yang Zhao’s sale of 4,782 shares of Common Stock to the Company on April 9, 2013 (at the market price of $2.86 per share), made for the purpose of covering certain tax liabilities related to the vesting of a restricted stock award, none of the Reporting Persons has effected any transaction in the Common Stock during the past 60 days.

(d)

Dr. Yang Zhao’s ex-spouse is entitled to: (i) all sales proceeds from Dr. Zhao’s January 1, 2005 option grant (representing vested and exercisable options relating to 46,250 shares of Common Stock); and (ii) 40% of after-tax proceeds of any other options granted to Dr. Zhao before May 17, 2010.

(e)

Not applicable.

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

On April 22, 2013, the Company, Parent and Merger Sub entered into the Merger Agreement. Concurrently with the execution of the Merger Agreement: (i) Parent and the Rollover Holders entered into the Contribution Agreement; (ii) the Company, Parent, the IDG Funds and certain of the Rollover Holders entered into a voting agreement dated as of April 22, 2013 (referred to herein as the “Voting Agreement,” as filed with this Schedule as Exhibit 7.04); (iii) Parent and Sponsor entered into an equity commitment letter dated as of April 22, 2013 (referred to herein as the “Equity Commitment Letter,” as filed with this Schedule as Exhibit 7.05); and (iv) Sponsor provided a limited guaranty in favor of the Company dated as of April 22, 2013 (referred to herein as the “Limited Guaranty,” as filed with this Schedule as Exhibit 7.06).

Pursuant to the Voting Agreement, the IDG Funds and those Rollover Holders party thereto committed to vote the shares of Common Stock over which they have voting control in favor of the adoption of the Merger Agreement, against certain competing transactions, and against any action, agreement or transaction that could reasonably be expected to materially impede, frustrate, interfere with, delay, postpone, adversely affect or prevent the consummation of the merger or the other transactions contemplated by the Merger Agreement. During the term of the Voting Agreement and subject to stated exceptions, the stockholders who are parties thereto may not offer for sale, sell, transfer, tender, pledge, encumber, assign or otherwise dispose of, or enter into any contract, option or other arrangement or understanding with respect to, or consent to the offer for sale, sale, transfer, tender, pledge, encumbrance, assignment or other disposition of, enter into a loan of, or otherwise grant a proxy or power of attorney (other than as set forth in the Voting Agreement) with respect to, such Common Stock.

As described in more detail in Item 2 of this Schedule, certain of the Rollover Holders are executive officers and employees of the Company and its subsidiaries.

Subject to the terms and conditions set forth in the Equity Commitment Letter, Sponsor has committed to purchase (or cause to be purchased), at or immediately prior to the consummation of the merger, up to $86.3 million of the equity securities of Parent. Parent has, in turn, agreed to use the invested funds only to: (i) fund, to the extent necessary, the aggregate merger consideration needed to acquire all of the Common Stock not already owned by Sponsor and the IDG Funds (other than shares held by MEMSIC as treasury stock or otherwise owned by Parent, Merger Sub or any wholly owned subsidiary of MEMSIC, dissenting shares, and shares that may be contributed by the Rollover Holders to Parent prior to the effective time of the Merger, pursuant to the Contribution Agreement); (ii) fund all other amounts payable pursuant to the Merger Agreement in satisfaction of all restricted stock awards, restricted stock units and stock options; and (iii) pay all fees, expenses and other amounts payable pursuant to the Merger Agreement.

The Sponsor has agreed to guarantee certain obligations of Parent under the Merger Agreement, on the terms and subject to the conditions set forth in the Limited Guaranty, in an amount up to $3.89 million. Such Limited Guaranty includes Sponsor’s obligation to pay any reverse termination fee (in the amount of $3.54 million, should it become payable), and other specified costs and expenses that may become payable by Parent in specified circumstances.
