VARI-L COMPANY ANNOUNCES ADJOURNMENT OF
SPECIAL MEETING OF SHAREHOLDERS

DENVER, Colorado — Vari-L Company, Inc. (OTCBB:VARL), a leading provider of advanced components for the wireless telecommunications industry, announced that the shareholders present at its special meeting held today have approved a motion to adjourn the special meeting of shareholders until May 5, 2003 at 11:00 a.m. MDT at Vari-L’s offices at 4895 Peoria St., Denver, Colorado. The purpose of the special meeting is to vote upon the sale of substantially all of Vari-L’s tangible and intangible assets to a wholly owned subsidiary of Sirenza Microdevices, Inc. (Nasdaq-SMDI) and the subsequent dissolution of Vari-L. Vari-L has adjourned the special meeting to permit further solicitation of proxies in order to establish a quorum and to obtain additional votes in favor of the asset sale and the subsequent dissolution of Vari-L.

Vari-L, whose shareholders are widely dispersed, believes that the additional time provided by this adjournment will allow it to obtain the votes necessary to approve the asset sale and the subsequent dissolution of Vari-L. The approval of the asset sale and the subsequent dissolution of Vari-L each require the affirmative vote of the holders of 3,626,047 shares of Vari-L’s common stock, which represent a majority of the outstanding shares as of the March 7, 2003 record date for the special meeting. As of April 28, 2003 at 2:10 p.m., Vari-L had received proxies for approximately 3.26 million shares in favor of the asset sale and the subsequent dissolution of Vari-L and approximately 92,000 shares against such proposals.

Vari-L mailed proxy statements to all shareholders of record on or about April 4, 2003 and encourages shareholders to complete and return the enclosed proxy card prior to the date of the adjourned meeting.

“We strongly encourage shareholders to carefully consider the proposals described in the proxy statement and to cast their vote on the enclosed proxy card whether or not they plan to attend the special meeting,” said Chuck Bland, CEO of Vari-L. “If shareholders do not return their proxy cards or instruct their brokers how to vote or vote in person at the meeting, then the effect will be a vote against the asset sale.”

On December 2, 2002, Vari-L announced a definitive agreement to sell substantially all of its assets to Sirenza. The transaction is subject to several closing conditions, including the approval of Vari-L shareholders. The boards of both companies have approved the transaction.

Forward Looking Statements

Some of the statements in this news release are “forward looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on a number of assumptions by us about the future, usually based on current conditions or on the broader expectations of others. These assumptions may or may not prove to be correct and, as a result, our own forward-looking statements may also be inaccurate. On the other hand, based on what we know today and what we expect in the future, we believe that the forward-looking statements we make in this report are reasonable. In most cases, when we use words like “believe,” “expect,” “estimate,” “anticipate,” “project,” “plan,” or “predict” to describe something which has not yet occurred, we are making a forward-looking statement.

We cannot list here all of the risks and uncertainties that could cause our actual future financial and operating results to differ materially from our historical experience and our present expectations or projections but we can identify many of them. For example, our future results could be affected by the overall market for various types of wireless communications products, the success of the specific products into which our products are integrated, governmental action relating to wireless communications, licensing and regulation, the accuracy of our internal projections as to the demand for certain types of technological innovation, competitors’ products and pricing, the success of new product development efforts, the timely release for production and the delivery of products under existing contracts, the ultimate outcome of pending and threatened litigation and regulatory action as well as those factors discussed in our Form 10-K for the year ended June 30, 2002. Our future results could also be affected by risks and uncertainties related to the proposed transaction with Sirenza, including whether such transaction is approved by Vari-L’s shareholders and can be completed and the timing of the closing of such transaction, the amount of additional loans that we incur under our bridge loan facility with Sirenza and whether the $5.3 million credit facility will be adequate to fund the Company’s operations, whether Sirenza will exercise its rights under the loan agreement in the event of default such as the right to accelerate the obligation to repay the loans outstanding, whether the costs of completing

the transaction exceed management’s estimates, and the reaction of our customers, vendors and distributors to proposed transaction. It is also important to remember that forward-looking statements speak only as of the date when they are made and we do not promise that we will publicly update or revise those statements whenever conditions change or future events occur. Accordingly, we do not recommend that any person seeking to evaluate our company should place undue reliance on any forward-looking statement in this report.
