Dear Tim:

This letter will confirm our agreement regarding the termination of your
employment with Vari-L Inc. ("Vari-L"), in connection with the Asset Purchase
Agreement (the "Purchase Agreement") by and among Sirenza Microdevices Inc.,
Olin Acquisition Corporation ("Buyer") and Vari-L. This mutual termination of
employment is contingent upon the Closing (as defined in the Purchase Agreement)
of the sale of Vari-L assets to Buyer contemplated by the Purchase Agreement.
All capitalized terms not otherwise defined herein shall have the meaning given
to them in the Purchase Agreement.

It is a condition to the Closing of the Purchase Agreement that, effective as of
the Closing, (i) you and Vari-L terminate your employment relationship with
Vari-L, including, without limitation, the Vari-L Company, Inc. Executive
Employment Agreement executed by you and Vari-L (the "Existing Employment
Agreement"), and (ii) you waive any and all potential claims against Vari-L
including, but not limited to, any severance benefits payable to you under the
Existing Employment Agreement. Pursuant to Section XIII of the Existing
Employment Agreement, you and Vari-L acknowledge and agree that your termination
from Vari-L shall be a termination by Mutual Agreement and as that is defined in
the Existing Employment Agreement, you are not entitled to any severance
benefits from Vari-L whatsoever.

Although Vari-L has no obligation to do so, in consideration for the promises
and agreements contained in this termination letter, including without
limitation, the Termination by Mutual Agreement of your employment with Vari-L
and release of all claims, Vari-L offers the following potential bonus
opportunity to you should you accept employment with Sirenza:

(a)      SIGNING BONUS: should you accept employment with Sirenza by executing
         Sirenza's standard offer letter (attached) on or before the Closing
         Date, Vari-L shall pay to you a bonus in the amount of $62,187.50
         ("Signing Bonus"). Said Signing Bonus shall be paid to you by Vari-L in
         a lump sum, less applicable taxes and withholding, as required by law,
         within five (5) business days of the Closing Date.

(b)      STAY BONUS: In the event that you accept employment with Sirenza and
         remain employed by Sirenza on the one-year anniversary date of the
         commencement of such employment, you will be entitled to receive from
         Vari-L an additional bonus payment in the amount of $62,187.50 ("Stay
         Bonus"). Said Stay Bonus to be paid in a lump sum, less applicable
         taxes and withholding, as required by law, within five (5) business
         days of the one year anniversary date of your employment with Sirenza.

         You must be employed with Sirenza on the anniversary date in order to
         be eligible for the Stay Bonus. In no event shall the Stay Bonus be
         prorated regardless of the reason for your separation from employment
         with Sirenza prior to the one year anniversary date. In no event shall
         the Stay Bonus be payable to you by any party other than Vari-L.

(c)      SEVERANCE PAYMENT. In the event that you accept employment with Sirenza
         and are terminated by Sirenza, other than for cause (as defined below),
         prior to the one-year anniversary date of the commencement of such
         employment, you will be entitled to receive from Vari-L a severance
         payment in an amount equal to (i) $109,375.00 less (ii) the Signing
         Bonus and the amount of any severance paid to you by Sirenza (the
         "Severance Payment"). Said Severance Payment to be paid in a lump sum,
         less applicable taxes and withholding, as required by law, within five
         (5) business days of your termination by Sirenza. For purposes of this
         letter agreement, the phrase "for cause" shall have the same meaning as
         set forth in your employment agreement with Sirenza. In no event will
         we be obligated pay you both the Severance Payment and the Stay Bonus.

Thus, we agree that, effective as of the Closing, our employment relationship
pursuant to the Existing Employment Agreement or otherwise is hereby terminated
by mutual agreement. You further agree on your own behalf, and on behalf of your
respective heirs, family members, executors, and assigns, that you hereby fully
and forever release Vari-L and its officers, directors, employees, investors,
