Item 1.01 Entry into a Material Definitive Agreement.

On August 8, 2012, Legend Parent, Inc., a Delaware corporation (“Parent”), and Legend Acquisition Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), delivered a waiver (the “Waiver Letter”) in which they waived certain of their rights under the Agreement and Plan of Merger (as amended, the “Merger Agreement”), dated as of July 2, 2012, by and among Parent, Merger Sub and MModal Inc. (the “Company”), which waiver has the effect of permitting the Company to release the 19 financial sponsors (excluding One Equity Partners IV, L.P., which is an affiliate of One Equity Partners V, L.P.) referred to in the Company’s Solicitation/Recommendation Statement on Schedule 14D-9, filed with the Securities and Exchange Commission (the “SEC”) on July 17, 2012, as amended, that entered into a confidentiality agreement with the Company between March 16, 2012 and April 11, 2012 from the provisions of any standstill with the Company. The foregoing description of the Waiver Letter does not purport to be complete and is qualified in its entirety by reference to the Waiver Letter, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

Item 8.01 Other Events

On August 8, 2012, the parties to the three purported class action lawsuits related to the Merger Agreement, which were subsequently consolidated into a single proceeding captioned In re MModal Inc. Shareholder Litigation, Consolidated Civil Action No. 7675-VCP, entered into a memorandum of understanding (the “MOU”) providing for the settlement of certain litigation in relation to Merger Sub’s pending tender offer (the “Offer”) and the Merger (as defined in the Merger Agreement) and pursuant to which Parent and Merger Sub waived certain rights under the Merger Agreement and related support agreement. The foregoing description of the MOU does not purport to be complete and is qualified in its entirety by reference to the MOU, which is filed as Exhibit 99.1 hereto and is incorporated herein by reference.

On August 8, 2012, the Company released the 19 financial sponsors (excluding One Equity Partners IV, L.P.) referred to above from the provisions of any standstill with the Company by delivering a waiver letter to each such sponsor in accordance with the terms of the MOU.

In addition, on August 8, 2012, Merger Sub extended the expiration date of the Offer until 11:59 p.m., New York City time, on August 14, 2012. The Offer had previously been scheduled to expire at 11:59 p.m., New York City time, on August 13, 2012. The press release announcing the extension of the Offer is filed as Exhibit 99.2 hereto and is incorporated herein by reference.

Important Additional Information and Where to Find It

This Current Report on Form 8-K (this “Current Report”) is neither an offer to purchase nor a solicitation of an offer to sell any shares of the common stock of the Company or any other securities. On July 17, 2012, affiliates of One Equity Partners (“OEP”) filed a tender offer statement on Schedule TO, including an offer to purchase, a letter of transmittal and related documents, with the SEC. Thereafter, the Company filed a solicitation/recommendation statement on Schedule 14D-9 with respect to the tender offer. The offer to purchase shares of the Company’s common stock is only being made pursuant to the offer to purchase, the letter of transmittal and related documents filed with such Schedule TO. Investors and security holders are urged to read both the tender offer statement (including an offer to purchase, a related letter of transmittal and the other offer documents) and the solicitation/recommendation statement regarding the tender offer, as they may be amended from time to time, because they contain important information that should be read carefully before making any decision with respect to the tender offer. The tender offer statement has been filed with the SEC by affiliates of OEP, and the solicitation/recommendation statement has been filed with the SEC by the Company. Investors and security holders may obtain a free copy of these statements, the merger agreement and other documents filed with the SEC at the website maintained by the SEC at www.sec.gov or by directing such requests to the information agent for the tender offer. In addition, the tender offer statement and related documentation may be obtained for free by directing such requests to Georgeson Inc., 199 Water Street, 26th Floor, New York, New York 10038, Toll-Free Telephone: (888) 505-6583 or email: MModal@georgeson.com, and the solicitation/recommendation statement and related documents may be obtained for free by directing such requests to the Company at Investor Relations, 9009 Carothers Parkway, Suite C-2, Franklin, Tennessee, or ir@mmodal.com.

Forward-Looking Statements

Information provided and statements contained in this Current Report that are not purely historical, such as statements regarding expectations about the tender offer or future business plans, prospective performance and opportunities, the expected timing of the completion of the transaction and the ability to complete the transaction considering the various closing conditions, are forward-looking statements within the meaning of Section 27A of the

Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. Such forward-looking statements only speak as of the date of this Current Report, and the Company assumes no obligation to update the information included in this Current Report. Statements made in this Current Report that are forward-looking in nature may involve risks and uncertainties. Accordingly, readers are cautioned that any such forward-looking statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict, including, without limitation, the possibility that the transaction does not close, the risk that business disruption relating to the transaction may be greater than anticipated, the failure to obtain any required financing on favorable terms and other specific risk factors discussed herein and in other releases and public filings made by the Company (including filings by the Company with the SEC). Although the Company believes that the expectations reflected in such forward-looking statements are reasonable as of the date made, expectations may prove to have been materially different from the results expressed or implied by such forward-looking statements. Unless otherwise required by law, the Company also disclaims any obligation to update its view of any such risks or uncertainties or to announce publicly the result of any revisions to the forward-looking statements made in this Current Report.
