Dear Xxxxxxx:

When you joined Powerwave, you received a letter outlining certain benefits that you would receive in case your employment was terminated in connection with a change of control of Powerwave. Since the date of your July 13, 2007 letter agreement (“Letter Agreement”), there have been certain changes to Internal Revenue Code Section 409A and the regulations thereunder. In order to comply with the regulations under Internal Revenue Code Section 409A, certain amendments are required to Letter Agreement. This letter is an amended and restated version of the Letter Agreement and supersedes the Letter Agreement.

In recognition of your value and contribution as Chief Product and Development Officer, we would like to provide you with reasonable financial certainty to enable you to concentrate on the growth and well being of Powerwave Technologies during your tenure with the Company.

As part of your executive benefits, we are providing you with this Severance Agreement, which provides that you will receive the severance benefits outlined below if in anticipation of, or within eighteen (18) months following a “Change in Control” of the Company, your employment is involuntarily terminated without “Cause”, or if you voluntarily terminate your employment for “Good Reason”. The terms “Change in Control”, “Cause” and “Good Reason” are defined in the attachment. Under this Severance Agreement your severance benefit is eighteen (18) months lump-sum pay at the rate of your then current annual salary for the year in which the termination occurs. This amount shall be subject to applicable federal, state and local tax withholdings and will be paid to you provided you execute a release of claims within the minimum period required by Section 201 of the Older Workers Benefit Protection Act of 1990, as amended, to make such release effective. The lump sum will be paid within fifteen (15) days after your execution of an unrevoked release (but not later than two and one-half (2 ¹ /2) months after the end of the calendar year following your termination of employment.)

Additionally, the Company will pay for existing group employee benefit coverage continuation under the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) as provided by the Company’s group Agreements for eighteen (18) months following the calendar month of your termination at regular employee rates.

Further, the Company will provide you with access to executive outplacement for eighteen (18) months. Outplacement will include the Executive Package at Xxx Xxxxx Xxxxxxxx or a comparable outplacement provider.

Benefits under this Agreement will require you to sign a Release and return the signed original to Powerwave. Please note that nothing in this agreement is intended to alter your employment status and that your employment with the Company remains on an “at-will” basis.

It is our hope that these provisions demonstrate to you our commitment and appreciation for your commitment to Powerwave. Please confirm your agreement with this letter by signing in the space below.

Respectfully,

Xxxxxx X. Xxxxxxx

President and CEO
