WHEREAS, at the Effective Time (as defined below), pursuant to the transactions contemplated by this Agreement and on the terms and subject to the conditions set forth herein, Merger Sub will merge with and into j2 Global in accordance with the Delaware General Corporation Law, as amended (the “DGCL”), whereupon the separate existence of Merger Sub shall cease and j2 Global shall be the surviving entity; and

WHEREAS, for U.S. federal income tax purposes, it is the intention of the parties hereto that the Merger shall qualify as a tax-free reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations promulgated thereunder.

NOW, THEREFORE, in consideration of the premises and agreements contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE 1

MERGER

Section 1.1 Merger. Subject to the terms and conditions of this Agreement and in accordance with Section 251(g) of the DGCL, Merger Sub shall be merged with and into j2 Global at the Effective Time. Following the Effective Time, the separate corporate existence of Merger Sub shall cease, and j2 Global shall continue as the surviving entity (the “Surviving Entity”), becoming a direct wholly-owned subsidiary of HoldCo.

Section 1.2 Effective Time.

(a) Subject to the provisions of this Agreement, as soon as practicable following the satisfaction or waiver of the conditions set forth in Section 4.1, j2 Global shall duly execute and

file a Certificate of Merger (the “Certificate of Merger”) substantially in the form set forth as Exhibit A hereto with the Secretary of State of the State of Delaware (the “Delaware Secretary”) as required by the DGCL. The Merger shall become effective as provided in the Certificate of Merger (the “Effective Time”).

(b) The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, (i) right and title to all assets (including real estate and other property) owned by, and every contract right possessed by, j2 Global and Merger Sub shall vest in the Surviving Entity, and (ii) all liabilities and obligations of j2 Global and Merger Sub shall become the liabilities and obligations of the Surviving Entity. The vesting of such rights, title, liabilities and obligations in the Surviving Entity shall not be deemed to constitute an assignment or an undertaking or attempt to assign such rights, title, liabilities and obligations. Immediately following the Effective Time, j2 Global agrees to file a certificate of amendment to the A&R Certificate (as defined below) to change the name of j2 Global to “j2 Cloud Services, Inc.,” and immediately thereafter, HoldCo agrees to file a certificate of amendment to the HoldCo A&R Certificate of Incorporation (as defined below) to change the name of HoldCo to “j2 Global, Inc.”

Section 1.3 Organizational Documents.

(a) HoldCo. In accordance with Section 251(g) of the DGCL, HoldCo agrees to file (and j2 Global as the sole stockholder of HoldCo agrees to approve the filing of) an amended and restated certificate of incorporation of HoldCo (substantially in the form set forth as Exhibit B hereto, the “HoldCo A&R Certificate of Incorporation”) with the Delaware Secretary prior to the Effective Time to be effective prior to and as of the Effective Time (without, for the avoidance of doubt, giving effect to any of the amendments contemplated by Section 1.3(b) of this Agreement) containing provisions identical to those in the Amended and Restated Certificate of Incorporation of j2 Global (the “A&R Certificate”) immediately prior to the Effective Time, except as otherwise permitted by Section 251(g) of the DGCL. HoldCo acknowledges that it has adopted bylaws substantially in the form set forth as Exhibit C hereto to be effective prior to and as of the Effective Time (the “HoldCo Bylaws”) containing provisions identical to those in the bylaws of j2 Global (the “j2 Global Bylaws”) in effect immediately prior to the Effective Time.

(b) Surviving Entity.

(i) At the Effective Time, the certificate of incorporation of j2 Global in effect immediately prior to the Effective Time shall be and remain the certificate of incorporation of the Surviving Entity, until otherwise thereafter amended as provided therein or by the DGCL.

(ii) In accordance with Section 251(g) of the DGCL, at the Effective Time, the j2 Global Bylaws shall be amended and restated in the form attached hereto as Exhibit D (the “A&R Bylaws”) and, as so effectuated, shall continue in full force and effect as the bylaws of the Surviving Entity until otherwise thereafter amended as provided therein or by the DGCL.

Section 1.4 Directors and Officers of the Surviving Entity. From and after the Effective Time, the members of the board of directors of the Surviving Entity shall be the

members of the board of directors of Merger Sub immediately prior to the Effective Time, and the officers of the Surviving Entity shall be the officers of Merger Sub immediately prior to the Effective Time, each to hold office as provided in the A&R Certificate and A&R Bylaws, until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal.

Section 1.5 Directors and Officers of HoldCo. From and after the Effective Time, the directors of HoldCo shall be the directors of j2 Global immediately prior to the Effective Time, and the officers of HoldCo shall be certain officers of j2 Global designated by the HoldCo Board, each to hold office as provided in the HoldCo A&R Certificate of Incorporation and HoldCo Bylaws, until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal.

Section 1.6 Conversion or Subsequent Merger. Following the Effective Time, upon receipt of the stockholder approval required under the DGCL, if so required, j2 Global shall convert to a Delaware limited liability company or merge with and into a Delaware limited liability company subsidiary. For U.S. federal income tax purposes, it is the intention of the parties hereto that such conversion or merger, as the case may be, shall be part of the same tax-free reorganization as the Merger.

Subject to Section 2.1, from and after the Effective Time, all of the outstanding certificates and book-entries which immediately prior to the Effective Time represented shares of j2 Global Stock shall be deemed for all purposes to evidence ownership of, and to represent, shares of HoldCo Stock into which the shares of j2 Global Stock formerly represented by such certificates and book-entries have been converted as provided in this Agreement with identical designations, rights, powers and preferences, and qualifications, limitations and restrictions. The registered owner on the books and records of HoldCo or its transfer agent of any outstanding stock certificate shall, until such certificate shall have been surrendered for transfer or otherwise accounted for to HoldCo or its transfer agent, be entitled to exercise any voting and other rights with respect to the applicable shares of HoldCo Stock into which the shares of j2 Global Stock have been converted as provided in this Agreement.

Section 3.4 Tax Characterization. Each party hereto shall use its reasonable best efforts to cause the Merger to constitute a tax-free reorganization within the meaning of Section 368 of the Code, and shall not take any actions reasonably likely to cause the Merger not to so qualify, or cause any such actions to be taken.
