Form of Restricted Stock Unit Purchase Agreement for use under Nuance Communications, Inc. 2000 Stock Plan (performance-based awards)

Restricted Stock Units. Pursuant to the Company’s 2000 Stock Plan, as amended from time to time (the “Plan”), a copy of which is attached to this Agreement as Exhibit A, the Company hereby grants to Grantee the number of Restricted Stock Units listed in Item B above on the terms and conditions set forth herein and in the Plan, the terms and conditions of the Plan being hereby incorporated into this Agreement by reference. In the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Agreement, the terms and conditions of the Plan shall prevail. Capitalized terms used and not defined in this Agreement will have the meanings set forth in the Plan.

Company’s Obligation to Pay. Each Restricted Stock Unit represents the right to receive one share of Common Stock of the Company, par value $0.001 (“Share”) after the Restricted Stock Unit has vested. Unless and until the Restricted Stock Units will have vested in the manner set forth in Section 3, Grantee will have no right to receive the Shares subject to the Restricted Stock Units. Prior to the actual issuance of any Shares subject to the Restricted Stock Units, such Restricted Stock Units will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

Vesting. Subject to Section 5, the Restricted Stock Units shall vest in accordance with the provisions set forth on Exhibit B, subject to Grantee’s continuing to be an employee, director or consultant of the Company or of an Affiliate (a “Service Provider”) through each vesting date. For the avoidance of doubt, Grantee would no longer be considered a Service Provider

Forfeiture upon Termination as Service Provider. If Grantee terminates service as a Service Provider, for any or no reason, prior to vesting, Grantee’s right to acquire Shares pursuant to such unvested Restricted Stock Units awarded by this Agreement will immediately terminate.

Payment After Vesting. Any Restricted Stock Units that vest in accordance with Section 3, or otherwise vest in accordance with the terms of the Plan, will be settled by the Company issuing Shares to Grantee, subject to the provisions of Section 7 below. The settlement of vested Restricted Stock Units will be completed by the issuance of the appropriate number of Shares as soon as practicable after vesting, but in each such case no later than the 15^th day of the third month following the end of the Company’s tax year that includes each applicable vesting date.

Rights as Stockholder. Neither Grantee nor any person claiming under or through Grantee will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Grantee.

Responsibility for Taxes. Grantee acknowledges that, regardless of any action taken by the Company or, if different, Grantee’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Grantee’s participation in the Plan and legally applicable to Grantee as a result of participation in the Plan (“Tax-Related Items”) is and remains Grantee’s responsibility and may exceed the amount (if any) withheld by the Company or the Employer. Grantee further acknowledges that Company and the Employer (i) make no representations or undertakings regarding the treatment of any

Withholding. Prior to the relevant taxable or tax withholding event, as applicable, Grantee agrees to make arrangements satisfactory to the Company to satisfy all Tax-Related Items. In this regard, Grantee authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations with regard to all Tax-Related Items by one or a combination of the following:

withholding from Grantee’s wages or other cash compensation otherwise payable to Grantee by the Company and/or the Employer; and/or

requiring Grantee to tender a payment in cash (or the cash equivalent) in an amount equal to the Tax-Related Items to the Company or its designee; and/or

withholding from the proceeds from the sale of Shares acquired upon settlement of the Restricted Stock Units, either through a voluntary sale or through a mandatory sale arranged by the Company (on Grantee’s behalf pursuant to this authorization without further consent); and/or

withholding in Shares to be issued upon settlement of the Restricted Stock Units, provided, however, that if Grantee is an officer of the Company within the meaning of Section 16 of the Exchange Act, the Company will withhold in Shares to be issued upon settlement of the Restricted Stock Units, unless the use of such withholding method is problematic under applicable tax or securities law or has materially adverse accounting consequences, in which case, the Committee (as constituted to satisfy Rule 16b-3 of the Exchange Act) will determine which of the other withholding methods set out in this Section 8(b) will be used; and/or

any other method determined by the Company and permitted under applicable laws.

Section 409A. This Agreement and the Restricted Stock Units granted hereunder are intended to meet the “short-term deferral” exception to the provisions of Section 409A of the Code and U.S. Department of Treasury regulations issued thereunder or to otherwise comply with Section 409A of the Code and the U.S. Department of Treasury regulations and guidance issued thereunder, to the extent applicable. Notwithstanding any provision of the Plan or this Agreement to the contrary, this Agreement and the Restricted Stock Units granted hereunder shall be interpreted and construed consistent with this intent. Notwithstanding the foregoing, the Company and its affiliates shall not be required to assume any increased economic burden in connection therewith. Neither the Company or any of its Affiliates, nor any of their respective directors, officers, managers, employees or advisers shall be liable to Grantee (or any other individual claiming a benefit through Grantee) for any tax, interest, or penalties Grantee might owe as a result of this Agreement and the Restricted Stock Units granted hereunder, or otherwise. Notwithstanding anything to the contrary in the Plan or this Agreement, the Company reserves the right, but is not obligated, to revise this Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Grantee, to comply with Section 409A of the Code or to otherwise avoid imposition of any additional tax or income recognition under Section 409A of the Code in connection with this grant of Restricted Stock Units; provided, however, that the Company makes no representation that this Agreement and the Restricted Stock Units granted hereunder will be exempt from, or will comply with, Section 409A of the Code, and makes no undertakings to preclude Section 409A of the Code from applying to this Agreement and the Restricted Stock Units granted hereunder or to ensure that it complies with Section 409A of the Code.

Damages. Grantee shall be liable to the Company for all costs and damages, including incidental and consequential damages, resulting from a disposition of the Restricted Stock Units which is not in conformity with the provisions of this Agreement.

Other than with respect to the Restricted Stock Units granted pursuant to, and subject to, this Agreement, neither Grantee nor any other person shall have any claim or right to be issued Shares. Having received a grant of Restricted Stock Units under the Plan shall not give Grantee any right to receive any other grant under the Plan. This grant of Restricted Stock Units is not an employment contract and nothing in this grant of Restricted Stock Units shall be deemed to create in any way whatsoever any obligation on Grantee’s part to continue in the employ or service of the Company, or an Affiliate (as applicable) or the Company or an Affiliate (as applicable) to continue Grantee’s employment or service relationship.

This grant of Restricted Stock Units and any Shares subject to the Restricted Stock Units, and the income from and value of same, are not part of normal or expected compensation for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, holiday pay, pension or retirement or welfare benefits or similar mandatory payments.

The Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Restricted Stock Units have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Grantee, the Company and all other interested persons.
