All Four Independent Proxy Voting Advisory Firms Recommend Against

Obrem Proposals to Take Over Company at May 20 Special Meeting

Proxy Governance Most Recent to Recommend Micrel Shareholders Vote

Against All Obrem Proposals

San Jose, CA, May 15, 2008 — Micrel, Incorporated (Nasdaq:MCRL) today reported that Proxy Governance, Inc., an independent proxy voting advisory firm, recommends that shareholders vote against all the proposals made by Obrem Capital Management (“OCM”) at the May 20, 2008 Special Meeting of Micrel shareholders. In referring to OCM’s proposals and nominees, Proxy Governance stated in its report: “This proxy challenge may single-handedly redefine the term “ill-advised.””

Proxy Governance joins the other independent proxy voting advisory firms, Glass Lewis & Co, RiskMetrics and Egan-Jones, in recommending that shareholders vote against OCM’s proposals to take over Micrel’s Board of Directors. Proxy Governance, Glass Lewis and Egan-Jones all recommend shareholders use the WHITE proxy card mailed to them by Micrel to place their votes and that shareholders should not vote the gold proxy card provided by OCM.

In its report, Proxy Governance also stated:

• “For a company with a non-zero probability of continuing on a stand-alone basis, the dissident slate is underwhelming: two former industry executives with sales and distribution experience, four investment analysts or managers, and no one with operational experience in the company’s primary business of semiconductor R&D, design and manufacturing. Four of the nominees have no prior public board experience, making the remaining two nominees – each, according to the dissident proxy, with one public board directorship under his belt – comparatively awash with experience.”

• “Shareholders, understandably, may feel they’ve been offered no choice at all: electing a new board so heavily committed to a sale, led by a core group of newly-minted investment managers so unprepared for other possible outcomes, may be the surest recipe for a fire sale of the company.”

• “In adopting the pill, we believe the board acted to protect shareholder interests from what it perceived to be a specific threat. Because the defensive measure has a limited duration and will not preclude a negotiated strategic transaction, we are unconvinced the proposal to repeal the rights plan is in the best interests of shareholders.”

Commenting on the Proxy Governance report, the Company said, “We appreciate Proxy Governance’s full support of our position on OCM’s attempt to take over Micrel and force a sale of the company during the most challenging market conditions the industry has seen in years. It echoes support we are hearing from large shareholders. We look forward to the May 20th vote so we can focus 100% on the business and creating value for all shareholders.”
