Exhibit 2.1

SHARE PURCHASE AGREEMENT

This Share Purchase Agreement (the “Agreement”) is effective as of August 14, 2015 (“Effective Date”) by and among TSMC Partners, Ltd., a British Virgin Islands company (“TSMC” or “Purchaser”), OmniVision Technologies, Inc. a company incorporated under the laws of Delaware, USA (“OVT”), OmniVision International Holding, Ltd. an exempted company incorporated under the Companies Law of Cayman Islands (“OmniVision Cayman”), and OmniVision Investment Holding (BVI) Ltd. a British Virgin Islands company (“OmniVision BVI”).  OVT, OmniVision Cayman, and OmniVision BVI may be collectively referred individually and collectively as “Seller” or “Sellers”.  The parties to this agreement may be referred to as a “Party” or collectively as the “Parties”.

WHEREAS OVT wholly owns all shares in OmniVision Cayman, which in turn wholly owns all shares in OmniVision BVI, which holds Seller’s shares in VisEra Cayman, and

WHEREAS TSMC wishes to purchase all shares owned by Seller in VisEra Holding Company (“VisEra Cayman”) and

WHEREAS Seller wishes to sell all its shares of VisEra Cayman in accordance with the terms of this Agreement,

NOW THEREFORE, in consideration of the mutual agreements and covenants contained herein, the Parties agree as follows:

SECTION 1

AUTHORIZATION AND SALE OF SECURITIES IN VISERA CAYMAN

1.1           Authorization.  Seller has, or before the Closing (as defined in Section 2.1) will have, duly authorized the sale pursuant to the terms and conditions hereof of certain shares in VisEra Cayman (“VisEra Stock”).

1.2           Sale of Securities.  Subject to the terms and conditions hereof, at the Closing, Seller will sell to TSMC, and TSMC agrees to purchase from OmniVision BVI, all shares of Seller’s shareholdings in VisEra Cayman at a purchase price of US$2.58 per share of VisEra Stock (the book value of VisEra Stock as of June 30, 2015).  Payment of the purchase price will be made by TSMC by check or wire transfer.

1.3           Post-Sale Price Reconciliation.  TSMC intends and will use commercially reasonable efforts to sell all of those shares in XinTec Inc. (“XinTec”) stock owned by VisEra Cayman (“XinTec Shares”) and acquired under this Agreement within 30 days (“Term”) after the date the XinTec Shares are released from restrictions from sale under Taiwan securities laws (“Release Date”), but in no event prior to the Closing, provided that such selling will not violate, or risk violating, any laws or regulations (including, but not limited to, insider trading laws) or will not

materially affect XinTec’s market price at the time of sale as determined by TSMC at its sole discretion. The Term shall be automatically extended for successive one-month periods until all the XinTec Shares are sold.  If the market price of XinTec Shares falls more than 30% below the market price of XinTec Shares on the Release Date, the Term will be automatically extended for 180 days from the Release Date.

(a)                                 Reconciliations.  On a weekly basis, TSMC will notify Seller of the amount of XinTec Shares sold, the date of sale and the sale price at which the shares were sold deducting all taxes and expenses incurred or expected to incur on the sale, including but not limited to securities transaction taxes, income taxes, and brokerage fees.  Once all XinTec Shares are sold, TSMC will calculate the total proceeds from the sales (“Net Share Proceeds”). If the Net Sale Proceeds of any shares sold exceeds the price of the XinTec Shares as reflected in VisEra Cayman’s financial books on the date the VisEra Stock price is determined under Section 1.2 (“Benchmark XinTec Share Price”), TSMC will pay Seller an amount equal to the difference between the Net Sale Proceeds and the Benchmark Share Price for each share sold.  If the Net Sale Proceeds of any shares sold is less than the Benchmark XinTec Share Price, Seller will pay TSMC an amount equal to the difference between the Net Sale Proceeds and the Benchmark Share Price for each share sold.

(b)                                 No Obligation to Sell or Confer. Nothing in this Section 1.3 shall be considered an obligation for TSMC to sell shares at any price, or to confer with Seller prior to selling XinTec shares.

(c)                                  Payment Terms.  The party due to receive money after reconciliation as set forth in this section will issue an invoice (or other written instrument) to the other party for the amount owed, and the other party has 10 days to dispute the amount due under the invoice.  The invoiced party will pay the amount invoiced net 30 days.  Payment of the reconciliation amount will be made by check or wire transfer.  In the event of a dispute the parties will meet within 10 days to resolve the dispute.  If after 10 days there is no resolution to the dispute, the owing party will pay the amount of the invoice net 30 days and may take all legal steps necessary to resolve the dispute.

SECTION 2

CLOSING; DELIVERY OF VISERA STOCK

2.1           Closings.  The closing of the purchase by TSMC and the sale by Seller of the VisEra Stock (“Closing”) shall be held at TSMC’s office on no later than 30 days after receiving all relevant government approvals for the Share Purchase Transaction and the Seagull Transaction, (including US, Taiwan, and China) , but in no event later than the date of the Seagull Acquisition, or at such other time and place as agreed to by Seller and TSMC (“Closing Date”).

2.2           Delivery.  At the Closing, Seller will (1) deliver to TSMC the VisEra Stock purchased by TSMC, in exchange for payment of the purchase price therefor, and (2) execute an agreement terminating the Amended and Restated Shareholders’ Agreement dated August 12, 2005 and the Amendments thereto (“Shareholders’ Agreement”), provided that, notwithstanding Section 6.1 of
