     On September 21, 2006, Simtek Corporation ("Simtek"), closed the sale of
11,531,654 shares of its common stock for an aggregate purchase price of
$4,555,000, pursuant to the terms of the Securities Purchase Agreement dated as

Partners, LP, Straus GEPT Partners, LP, SF Capital Partners Ltd., Brian Alleman,

agreement (the "RR Agreement"), pursuant to which Simtek has agreed to register
under the Securities Act of 1933, as amended, the resale by the Purchasers of
the shares issued and shares issuable upon exercise of the warrants. Forms of
the Purchase Agreement, RR Agreement and warrant are included as exhibits to
this filing.

     Simtek is a party with certain of the Purchasers to previous financing

"Renaissance Entities") acquired convertible debentures from Simtek in 2002,
common stock and warrants from Simtek in 2003 and common stock from Simtek in

Simtek in 2004 and common stock from Simtek in 2005; and (c) Straus Partners,
LP, Straus GEPT Partners, LP, Big Bend XXVII Investments, L.P. and Crestview
Capital Master LLC acquired common stock from Simtek in 2005, in each case as
previously disclosed. Robert Pearson, a director of Simtek, is also a Senior
Vice President of RENN Capital Group, Inc., which is an affiliate of the
Renaissance Entities. Certain of the Purchasers are also officers of Simtek.
Brian Alleman is Chief Financial Officer, Steven Hayes is Vice President of
Sales and John C. McComb is Vice President of Worldwide Operations of
Simtek. Alfred Stein, a director of Simtek, is also the trustee for The A.J.
Stein Family Trust and The A.J. Stein Family Partnership. Brian Stein and Toni
Stein are family members of Alfred Stein, director of Simtek.

     The description of the transaction described in this report does not
purport to be complete and is qualified in its entirety by reference to the
Purchase Agreement (and the exhibits thereto). The Purchase Agreement (and the
exhibits thereto) are included to provide investors and security holders with
information regarding their terms. They are not intended to provide any other
factual information about Simtek or the Purchasers. The Purchase Agreement
contains representations and warranties the parties thereto made to and solely
for the benefit of each other. The assertions embodied in those representations
and warranties are qualified by information in confidential disclosure schedules
that the parties have exchanged in connection with signing the Purchase
Agreement. Accordingly, investors and security holders should not rely on the
representations and warranties as characterizations of the actual state of
facts, since they were only made as of the date of the Purchase Agreement and
are modified in important part by the underlying disclosure schedules. Moreover,
information concerning the subject matter of the representations and warranties
may change after the date of the Purchase Agreement, which subsequent
information may or may not be fully reflected in Simtek's public disclosures.
