EXHIBIT A

FORM OF IRREVOCABLE PROXY

IRREVOCABLE PROXY

The undersigned shareholder (“Shareholder”) of GMARKET INC., a corporation organized under the laws of the Republic of Korea (the “Company”), hereby irrevocably (to the fullest extent permitted by law) appoints and constitutes JOHN J. DONAHOE, ROBERT H. SWAN, LORRIE M. NORRINGTON, MICHAEL R. JACOBSON and EBAY KTA (UK) LTD., a company organized under the laws of the United Kingdom (“Acquisition Sub”), and each of them, the attorneys and proxies of Shareholder, with full power of substitution and resubstitution, to the full extent of Shareholder’s rights with respect to: (i) the outstanding shares of capital stock of the Company owned of record by Shareholder as of the date of this proxy, which shares are specified on the final page of this proxy; (ii) the outstanding American Depositary Shares of the Company owned of record by Shareholder as of the date of this proxy, which shares are specified on the final page of this proxy; and (iii) any and all other shares of capital stock and/or American Depositary Shares of the Company that Shareholder may acquire on or after the date hereof. (The shares of the capital stock and American Depositary Shares of the Company referred to in clauses “(i)” through “(iii)” of the immediately preceding sentence are collectively referred to as the “Shares.”) Upon the execution hereof, all prior proxies given by Shareholder with respect to any of the Shares are hereby revoked, and Shareholder agrees that no subsequent proxies will be given with respect to any of the Shares relating to any of the matters referred to in this proxy.

This proxy is irrevocable, is coupled with an interest and is granted in connection with, and as security for, the Agreement to Tender and Voting Agreement, dated as of the date hereof, among eBay Inc., a Delaware corporation (“Parent”), Acquisition Sub and Shareholder (the “Agreement to Tender”), and is granted in consideration of Parent and Acquisition Sub entering into the Share Allocation and Tender Offer Agreement, dated as of the date hereof, among Parent, Acquisition Sub and the Company (the “Master Agreement”). Capitalized terms used but not otherwise defined in this proxy shall have the meanings assigned to such terms in the Agreement to Tender, or, if not defined therein, in the Master Agreement.

The attorneys and proxies named above will be empowered, and may exercise this proxy to attend and vote the Shares for and on behalf of Shareholder at any meeting of the shareholders of the Company, however called, and in connection with any written action by consent of shareholders of the Company and to instruct the Depositary to vote the Company Shares represented by Company ADSs held by Shareholder at such meeting:

(a) in favor of each of the actions, transactions and other matters contemplated by the Master Agreement, including: (i) the election of the Parent Designees to the board of directors of the Company in accordance with the terms of the Master Agreement; and (ii) the other Voting Proposals; and

(b) against the following actions (other than the transactions contemplated by the Master Agreement, including the Voting Proposals): (i) any merger, consolidation or other business combination involving the Company or any subsidiary of the Company; (ii) any Acquisition Proposal; (iii) any reorganization, recapitalization, dissolution or liquidation of the Company or any subsidiary of the Company; (iv) any change in the board of directors of the Company; (v) any amendment to the Company’s articles of incorporation, bylaws or other similar charter document; (vi) any material change in the capitalization of the Company or the Company’s corporate structure; and (vii) any other action which is intended, or would reasonably be expected to impede, delay, postpone or materially and adversely affect any of the transactions contemplated by the Master Agreement or cause the Minimum Condition or any of the other Offer Conditions to not be satisfied.

The attorneys and proxies named above will also be empowered, and may exercise this proxy to prepare and execute the minutes of such meeting of the shareholders or such written action by consent of shareholders and take any and all actions relating thereto in the name of Shareholder (including, without limitation, obtaining notarization of such minutes or written actions). Shareholder may vote the Shares on all other matters not referred to in this proxy, and the attorneys and proxies named above may not exercise this proxy with respect to such other matters.

This proxy shall be binding upon the heirs, estate, executors, personal representatives, successors and assigns of Shareholder (including any transferee of any of the Shares).

This proxy will automatically terminate and be of no further force or effect on July 1, 2009.

Any term or provision of this proxy that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, Shareholder agrees that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this proxy shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.
