(a) Settlement Amount. Subject to Section 4(b) hereof, the Company shall deliver to the Grantee on each vesting date a number of shares of Common Stock equal to the aggregate number of Granted Units that vest as of such date; provided, however, that no shares of Common Stock will be issued in settlement of this award unless the issuance of shares complies with all relevant provisions of law and the requirements of any stock exchange upon which the shares of Common Stock may then be listed. No fractional shares of Common Stock will be issued. The Company will pay cash in respect of fractional shares of Common Stock.

(b) Withholding Requirements. Unless the Company shall have satisfied the tax withholding from other amounts payable to the Grantee, the Company shall withhold from the

SECTION 6. MISCELLANEOUS PROVISIONS.

(a) No Retention Rights, No Future Awards. Nothing in this award or in the Plan shall confer upon the Grantee any right to any future Awards and to continue in Continuous Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining the Grantee) or of the Grantee, which rights are hereby expressly reserved by each, to terminate his or her Continuous Service at any time and for any reason, with or without cause.

(b) Award Unfunded. The Granted Units represent an unfunded promise. The Grantee’s rights with respect to the Granted Units are no greater than the rights of a general unsecured creditor of the Company.

(c) Notice. Whenever under this Agreement it becomes necessary to give notice, such notice shall be in writing, signed by the party or parties giving or making the same, and shall be served on the person or persons for whom it is intended or who should be advised or notified, by Federal Express (or other similar overnight service) or by registered or certified mail, with postage and fees prepaid. Notice shall be addressed to the Company at its principal executive office and to the Grantee at the address that he or she most recently provided in writing to the Company.

(d) Entire Agreement. This Agreement, the Notice and the Plan constitute the entire contract between the parties hereto with regard to the subject matter hereof. They supersede any other agreements, representations or understandings (whether oral or written and whether express or implied) which relate to the subject matter hereof.

(e) Waiver. No waiver of any breach or condition of this Agreement shall be deemed to be a waiver of any other or subsequent breach or condition whether of like or different nature.

whether or not any such person shall have become a party to this Agreement and have agreed in writing to be joined herein and be bound by the terms hereof.

(g) Choice of Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York (regardless of the law that might otherwise govern under applicable New York principles of conflict of laws).

SECTION 7. RESTRICTIVE COVENANTS.

(a) Confidentiality. The Grantee shall not disclose to anyone or make use of any trade secret or proprietary or confidential information of the Company or an Affiliate, including such trade secret or proprietary or confidential information of any customer or other entity to which the Company owes an obligation not to disclose such information, which Grantee acquires during the period of employment, including, without limitation, records kept in the ordinary course of business, except (i) as such disclosure or use may be required or appropriate in connection with Grantee’s work as an employee of the Company or an Affiliate, (ii) when required to do so by a court of law, governmental agency or administrative or legislative body (including a committee thereof) with apparent jurisdiction to order Grantee to divulge, disclose or make accessible such information or (iii) as to such confidential information that becomes generally known to the public or trade without his or her violation of this Section 7(a). The Grantee hereby sells, assigns and transfers to the Company all of Grantee’s right, title and interest in and to all inventions, discoveries, improvements and copyrightable subject matter (the “Rights”) that, during Grantee’s employment, are made or conceived by him or her, alone or with others, and that relate to the Company or an Affiliate’s present business or arise out of any work Grantee performs or information Grantee receives regarding the business of the Company or an Affiliate while employed by the Company or an Affiliate. The Grantee shall fully disclose to the Company or an Affiliate as promptly as possible all information known or possessed by him or her concerning the Rights, and upon request by the Company or an Affiliate and without any further compensation in any form to Grantee by the Company or an Affiliate, but at the expense of the Company or an Affiliate, execute all applications for patents and copyright registrations, assignments thereof and other applicable instruments and do all things that the Company or an Affiliate may reasonably deem necessary to vest and maintain in it the entire right, title and interest in and to all such Rights.

(b) Noncompete; Non Nonsolicition. For and in consideration of the compensation to be paid by the Company pursuant to the terms hereof, and in recognition of the fact that the Grantee will have access to confidential information and other valuable rights of the Company, the Grantee covenants and agrees that he will not, at any time during his employment with the Company and for a period of twelve (12) months thereafter, directly or indirectly, engage in any business or in any activity related to the development, sale, production, manufacturing, marketing or distribution of products or services that are in competition with products or services that the Company or any of its subsidiaries produces, sells, manufactures, markets, distributes or has interest in, in any state or foreign country in which the Company or any of its subsidiaries then conducts business or reasonably has plans to conduct business. It is not the intent of this covenant to bar the Grantee from employment in any company whose general business is the manufacture of communications equipment or delivery of communications services, only to limit specific and direct competition with the Company. Notwithstanding the foregoing, nothing

4

contained in this Agreement shall prevent the Grantee from being an investor in securities of a competitor listed on a national securities exchange or actively traded over-the-counter so long as such investments are in amounts not significant as compared to his total investments or to the aggregate of the outstanding securities of the issuer of the same class or issue of the specific securities involved. The Grantee further agrees that during his employment by the Company and for a period of twelve (12) months thereafter, the Grantee shall not, directly or indirectly, induce, attempt to induce, or aid others in inducing, an exempt Grantee of the Company to accept employment or affiliation with another firm or corporation engaging in such business or activity of which the Grantee is an Grantee, owner, partner or consultant.

(c) Geographic Scope. The Company and the Grantee agree that the duration and geographic scope of the Restrictive Covenant provision set forth in this Section 7 are reasonable. In the event that any court of competent jurisdiction determines that the duration or the geographic scope, or both, are unreasonable and that such provision is to that extent unenforceable, the Company and the Grantee hereto agree that the provision shall remain in full force and effect for the greatest time period and in the greatest area that would not render it unenforceable. The Company and the Grantee intend that this provision shall be deemed to be a series of separate covenants, one for each and every county of each and every state of the United States of America and each and every political subdivision of each and every country outside the United States of America where this provision is intended to be effective.

SECTION 8. CLAW BACK

If a Grantee violates the requirements of Section 7 of this Agreement, then in addition to all remedies in law and/or equity available to the Company, Grantee shall forfeit all unvested Granted Units and vested Granted Units for which delivery of the underlying shares of Common Stock has not occurred. In addition, with respect to Granted Units for which shares of Common Stock were previously issued to the Grantee pursuant to Section 4 hereof, the Grantee shall immediately pay to the Company the Fair Market Value of such Common Stock on the date(s) such Granted Units vested, without regard to any taxes that may have been deducted from such amount.
