This letter sets forth the terms of Your employment at Carrier Access Corporation, (the “Company”).

BONUSES. Commencing with the Fiscal Year 2007, in addition to Base Salary, You will become eligible for a quarterly incentive and annual bonus plan, with a target bonus rate of 100% of Your annual base salary base salary (i.e., $350,000).

STOCK OPTIONS. With the commencement of Your employment, and as a condition of the non-competition terms as set forth in Section 8 below and Exhibit C attached hereto, I will recommend to the Carrier Access Board of Directors that You be granted a non-qualified stock option to purchase 500,000 shares of Carrier Access Common Stock (the “Option”).

Notwithstanding the foregoing, You may (a) provide up to twenty (20) hours of consulting services to Openwave Systems, Inc. during the period from the Effective Date through December 31, 2006, and (b) serve on the Board of Directors of two (2) other companies or organizations, provided however that (i) the foregoing activities do not materially interfere, individually or in the aggregate, with the performance of Your duties and responsibilities hereunder and (ii) with respect to other board services, You obtain the approval of the CEO and Board of Directors prior to joining any such board, and such other board service does not require that You attend more than four (4) meetings in person per year in total.

8.	RESTRICTIVE COVENANTS/PROTECTION OF PROPRIETARY INFORMATION.

INTENT. The parties hereto recognize that Your knowledge and skill are a material factor in inducing the Company to enter into this Agreement. Further, in the course of Your employment,

and because of the nature of Your responsibilities, You will acquire valuable and confidential information and trade secrets with regard to the Company’s business operation, including, but not limited to, Company’s existing and contemplated services and products, documentation, technical data, intellectual property and other proprietary information, business and financial methods and practices, plans, pricing, lists of Company’s customers and prospective customers, methods of obtaining customers, financial and operational data of Company’s present and prospective customers, and the particular business requirements of the Company’s present and prospective customers. In addition, You may develop on behalf of the Company, a personal acquaintance with some of the Company’s customers and prospective customers. As a consequence, You will occupy a position of trust and confidence with respect to the Company’s affairs and its services. In view of the foregoing, and in consideration of the remuneration paid and to be paid to You, You agree that it is reasonable and necessary for the protection of the goodwill and business of Company that You make the covenants contained in Sections 8(b) and 8(c) below regarding the conduct of You during and after Your employment relationship with the Company, and that the Company will suffer irreparable injury if You engage in conduct prohibited thereby.

NON-COMPETITION AND NON-SOLICITATION. For a period beginning on the Effective Date and ending one year after You cease to be employed by the Company, You, directly or indirectly, whether as employee, owner, sole proprietor, partner, director, member, consultant, agent, founder, co-venturer or otherwise, will not violate the Non-Compete and Non-Solicitation obligations and terms herein, including but not limited to those set forth in Exhibit C, attached hereto.

CONFIDENTIALITY.

(i) COMPANY’S INFORMATION. You agree that any and all of Company’s confidential and proprietary information, including, but not limited to, the matters contained in Section 8(a) above and all intellectual property rights therein, are and shall remain the sole and exclusive property of Company. While in the employ of Company, or at any time thereafter, You will not, directly or indirectly, communicate or divulge to or use for Your benefit or for the benefit of any other person, firm, association or corporation, any of Company’s trade secrets or confidential information, including, by way of illustration, the matters contained in Section 8(a) above, or which were communicated to or otherwise learned of or acquired by You in the course of Your employment with Company, except that You may disclose such matters to the extent that disclosure is required,

BLUE PENCIL: In the event any court of competent jurisdiction shall determine that the scope, time or territorial restrictions set forth are unreasonable, then it is the intention of You and Company that such restrictions be enforced to the fullest extent which the court deems reasonable, and this Agreement shall thereby be reformed.

PAID TIME OFF. Carrier Access will provide You with PTO days (paid time off) and Holidays. Currently there are eight (8) observed holidays. You will accrue twenty (20) PTO days on a per pay period basis as follows: 160 hrs / 26 pay periods = 6.15 hrs accrued each pay period.

For the purposes of this Agreement, the term “Covenant Area” shall be and mean all cities, counties, states, and countries in North America, South America, Asia, Middle East and Europe, in which the business of the Company or its affiliates is then being conducted, its services are being provided or its products are being sold.

NON-SOLICITATION. In addition to the foregoing, You shall not during the Covenant Period, as defined above, induce or attempt to induce any person (i) engaged or employed currently or within the prior twelve (12) months (whether part-time or full-time) by any of the Company (or any of its Affiliates), in any capacity, to leave the employ of or engagement with any of the Company (or any of its Affiliates), or to cease providing the services to or on behalf of any of the Company (or any of its Affiliates), then provided by such person, or in any other manner seek to engage or employ any such person (whether or not for compensation) in any capacity, or (ii) that is then or has been within the twelve (12) months prior to Your cessation of employment with the Company a customer or supplier

with respect to the Business to do business with any other persons or entities so as to interfere, in any way, directly or indirectly, with the business relationship between any of the Company (or any of its Affiliates)and any of their customers or suppliers.

You acknowledge that the Company may be irreparably harmed if You default in Your obligations under this Exhibit C and that it would be extremely impracticable to measure the resulting damages. Accordingly, the Company, in addition to any other available rights or remedies, may sue in equity for specific performance to enforce its rights under this Exhibit C, and You expressly waive the defense that a remedy in damages will be adequate for such a default.

The parties intend that the covenants and agreements contained in this Exhibit C and the Agreement shall be deemed to be a series of separate covenants and agreements. If, in any judicial proceeding, a court shall refuse to enforce all of the separate covenants deemed included in this Exhibit C and the Agreement, then such unenforceable covenants shall be deemed eliminated from the provisions of this Agreement for the purpose of such proceeding to the extent necessary to permit the remaining separate covenants to be enforced in such proceeding. If any one or more of the covenants contained in this Agreement is for any reason held to be excessively broad as to duration, geographical scope, activity or subject, the parties request that the applicable court construe it by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable law as then in effect.
