(c) Acquisition for Investment. Such Purchaser is acquiring the Securities solely for its own account and not with a view to or for sale in connection with the distribution thereof.

(d) Restricted Securities. Such Purchaser understands that the Securities have not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of such Purchaser’s representations as expressed herein. Such Purchaser understands that the Securities are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, such Purchaser must hold the Securities indefinitely unless they are registered with the Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. Such Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of such Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy. Such Purchaser understands that no United States federal or state agency or any government or governmental agency has passed upon or made any recommendation or endorsement of the Securities.

(e) No General Solicitation. Such Purchaser acknowledges that the Securities were not offered to such Purchaser by means of any form of general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (i) any advertisement, article, notice or other communication published in any newspaper, magazine, or

Certificate Legend

Section 5.1 Legend.

(a) Each certificate representing the Shares and the Warrant Shares shall be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend required by applicable state securities or “blue sky” laws) until such legend may be removed as provided in subsection (b) below:

“THE SHARES OF COMMON STOCK REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR IF APPLICABLE, STATE SECURITIES LAWS. THESE SHARES OF COMMON STOCK MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SHARES OF COMMON STOCK UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO NUANCE COMMUNICATIONS, INC. THAT SUCH REGISTRATION IS NOT REQUIRED.”

(b) The Company agrees to reissue certificates representing any of the Shares or Warrant Shares, without the legend set forth above, if at such time, prior to making any transfer of any such Securities, such holder thereof shall give written notice to the Company describing the manner and terms of such transfer and removal as the Company may reasonably request; provided that such legends shall not be removed and such proposed transfer will not be effected until: (i) such shares of Common Stock are registered under the Securities Act; or (ii) such holder provides the Company with an opinion of counsel acceptable to the Company to the effect that a public sale, assignment or transfer of the shares of Common Stock may be made without registration under the Securities Act and applicable state securities or “blue sky” laws. In the case of any proposed transfer under this Section 5.1, the Company shall in no event be required, in connection therewith, to qualify to do business in any state where it is not then qualified or to take any action that would subject it to tax or to general service of process in any state where it is not then subject. The restrictions on transfer contained in this Section 5.1 shall be in addition to, and not by way of limitation of, any other restrictions on transfer contained in any other section of this Agreement.

ARTICLE VI

Termination

Section 6.1 Termination. This Agreement may be terminated at any time prior to the Closing Date by (a) the mutual written consent of the Company and the Purchasers, or (b) any party if the Closing Date has not occurred by July 14, 2009; provided, however, that the right to terminate pursuant to this Section 6.1 shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Closing to occur on or before such date, and such action or failure to act constitutes a breach of this Agreement.

Section 6.2 Effect of Termination. In the event of a termination by the Company or the Purchasers, written notice thereof shall forthwith be given to the other party and the transactions contemplated by this Agreement shall be terminated without further action by any party. If this Agreement is terminated as provided in Section 6.1 herein, this Agreement shall become void and of no further force or effect, except for Section 3.2, this Section 6.2 and Article VII herein, which shall survive the termination of this Agreement. Nothing in this Section 6.2 shall be deemed to release the Company or any Purchaser from any liability for any breach of this Agreement, or to impair the rights of the Company or such Purchaser to compel specific performance by the other of its obligations under this Agreement.

ARTICLE VII
