AMENDMENT NO. 1 TO AGREEMENT AND PLAN OF MERGER

THIS AMENDMENT NO. 1 TO THE AGREEMENT AND PLAN OF MERGER is entered into this 2nd day of August, 2012 (this “Amendment”), by and among Legend Parent, Inc., a Delaware corporation (“Parent”), Legend Acquisition Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”) and MModal Inc., a Delaware corporation (the “Company” and, together with Parent and Merger Sub, the “Parties”).

WHEREAS, the Parties have entered into an Agreement and Plan of Merger, dated as of July 2, 2012 (the “Merger Agreement”), providing for, among other things, the merger of Merger Sub with and into the Company, with the Company continuing as the surviving corporation;

WHEREAS, Merger Sub commenced the Offer on July 17, 2012;

WHEREAS, pursuant to Section 7.4 of the Merger Agreement, the Merger Agreement may be amended by an instrument in writing signed by each of the Parties; and

WHEREAS, each of the Parties desires to amend and supplement the Merger Agreement in certain respects as described in this Amendment, and the Company hereby reaffirms the Company Recommendation.

NOW, THEREFORE, in consideration of the premises and mutual agreements hereinafter set out and of other consideration (the receipt and sufficiency of which are acknowledged), the Parties agree as follows:

1. Definitions. Except as otherwise indicated herein or unless the context otherwise requires, capitalized terms used but not defined herein shall have the meanings ascribed thereto in the Merger Agreement.

2. Amendments to the Merger Agreement.

“In addition, notwithstanding anything to the contrary set forth in this Agreement, Merger Sub shall have the right in its sole discretion to extend (or re-extend) the Offer beyond any then-scheduled expiration of the Offer for one or more periods, in consecutive increments of up to ten (10) Business Days each, the length of each such period to be determined by Parent in its sole discretion (or such longer period as Parent and the Company may mutually agree) to the extent all of the Offer Conditions have been satisfied or waived and the Debt Financing has not been received by Parent (either directly or through its subsidiaries) and the lenders party to the Debt Commitment Letter have not definitively and irrevocably confirmed to Parent and Merger Sub that the Debt Financing in an amount sufficient to consummate the Offer, the Merger and the other transactions contemplated herein will be available at the Offer Closing on the terms and conditions set forth in the Debt Commitment Letter.”

“(A) either (x) any Offer Condition shall not have been satisfied or waived, or (y) the Debt Financing shall not have been received by Parent (either directly or through its subsidiaries) and the lenders party to the Debt Commitment Letter shall not have definitively and irrevocably confirmed to Parent and Merger Sub that the Debt Financing in an amount sufficient to consummate the Offer, the Merger and the other transactions contemplated herein will be available at the Offer Closing on the terms and conditions set forth in the Debt Commitment Letter, and”.

“Each of Parent and Merger Sub acknowledges and agrees that the obtaining of the Financing is not a condition to the Merger Closing, and reaffirms its obligations under this Section 5.12.”

“(A) (x) all the Offer Conditions shall have been satisfied or waived (other than those conditions that by their nature are to be satisfied by actions taken at the Offer Closing) and the Debt Financing has been received by Parent (either directly or through its subsidiaries) or the lenders party to the Debt Commitment Letter have definitively and irrevocably confirmed to Parent and Merger Sub that the Debt Financing in an amount sufficient to consummate the Offer, the Merger and the other transactions contemplated herein will be available at the Offer Closing on the terms and conditions set forth in the Debt Commitment Letter, in each case, as of the Expiration Date and (y) Parent shall have failed to effect the Offer Closing promptly (and, in any event, within three (3) Business Days) thereafter in accordance with Section 1.1(a), or (B) (x) all of Offer Conditions shall have been satisfied or waived as of the Expiration Date (without giving effect to any extension of the expiration date due solely to the failure to obtain Debt Financing), (y) the Marketing Period has ended and (z) Parent shall have failed to effect the Offer Closing promptly (and, in any event, within three (3) Business Days) after the later of (x) and (y) of this subclause (B) in accordance with Section 1.1(a); or”

5. Counterparts.
