Exhibit 10.94

CATALYST SEMICONDUCTOR, INC.

SEVERANCE AGREEMENT

This Severance Agreement (the “Agreement”) is made and entered into by and between Irvin Kovalik (“Employee”) and Catalyst Semiconductor, Inc., a Delaware Corporation (the “Company”), effective as of August 23, 2005 (the “Effective Date”).

RECITALS

1.             It is expected that the Company from time to time will consider the possibility of an acquisition by another company or other change of control.  The Board of Directors of the Company (the “Board”) recognizes that such consideration can be a distraction to Employee and can cause Employee to consider alternative employment opportunities.  The Board has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication and objectivity of Employee, notwithstanding the possibility, threat or occurrence of a Change of Control.

2.             The Board believes that it is in the best interests of the Company and its stockholders to provide Employee with an incentive to continue his or her employment and to motivate Employee to maximize the value of the Company for the benefit of its stockholders.

3.             The Board believes that it is imperative to provide Employee with certain benefits upon Employee’s termination of employment without cause or following a Change of Control.  These benefits will provide Employee with enhanced financial security and incentive and encouragement to remain with the Company.

4.             Certain capitalized terms used in the Agreement are defined in Section 5 below.

(a)           delivered in full, or

(b)                                 delivered as to such lesser extent which would result in no portion of such severance benefits being subject to excise tax under Section 4999 of the Code,

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by Employee on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code.  Unless the Company and Employee otherwise agree in writing, any determination required under this Section 4 will be made in writing by the Company’s independent public accountants immediately prior to Change of Control (the “Accountants”), whose determination will be conclusive and binding upon Employee and the Company for all purposes.  For purposes of making the calculations required by this Section 4, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code.  The Company and Employee will furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section.  The Company will bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 4.

5.             Definition of Terms.  The following terms referred to in this Agreement will have the following meanings:

(a)           Benefit Plans.  “Benefit Plans” means plans, policies or arrangements that the Company sponsors (or participates in) and that immediately prior to Employee’s termination of employment provide Employee and/or Employee’s eligible dependents with medical, dental, and/or vision benefits.  Benefit Plans do not include any other type of benefit (including, but not by way of limitation, disability, life insurance or retirement benefits).  A requirement that the Company provide Employee and Employee’s eligible dependents with coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than that provided to Employee and Employee’s

5

eligible dependents immediately prior to Employee’s termination of employment.  Notwithstanding any contrary provision of this Section 5(a), but subject to the immediately preceding sentence, the Company may, at its option, satisfy any requirement that the Company provide coverage under any Benefit Plan by (i) reimbursing Employee’s premiums under COBRA after Employee has properly elected continuation coverage under COBRA (in which case Employee will be solely responsible for electing such coverage for Employee and Employee’s eligible dependents), or (ii) instead providing coverage under a separate plan or plans providing coverage that is no less favorable or by paying Employee a lump sum payment sufficient to provide Employee and Employee’s eligible dependents with equivalent coverage under a third party plan that is reasonably available to Employee and Employee’s eligible dependents.

(c)           Change of Control.  “Change of Control” means the occurrence of any of the following:

(i)    the sale, lease, conveyance or other disposition of all or substantially all of the Company’s assets to any “person” (as such term is used in Section 13(d) of the Securities Exchange Act of 1934, as amended), entity or group of persons acting in concert;

(ii)   any person or group of persons becoming the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing 50% or more of the total voting power represented by the Company’s then outstanding voting securities;

(iii)  a merger or consolidation of the Company with any other corporation, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its controlling entity) at least 50% of the total voting power represented by the voting securities of the Company or such surviving entity (or its controlling entity) outstanding immediately after such merger or consolidation; or

(iv)  a contest for the election or removal of members of the Board that results in the removal from the Board of at least 50% of the incumbent members of the Board.

(e)           Disability.  “Disability” will mean that Employee has been unable to perform the principal functions of Employee’s duties due to a physical or mental impairment, but only if such inability has lasted or is reasonably expected to last for at least six months.  Whether Employee has a Disability will be determined by the Board based on evidence provided by one or more physicians selected by the Board.

(f)            Good Reason.  “Good Reason” means (without Employee’s consent) (i) a material reduction in Employee’s title, authority, status, or responsibilities, (ii) the reduction of Employee’s aggregate base salary and target bonus opportunity as in effect immediately prior to such reduction (other than a reduction applicable to executives generally), or (iii) a relocation of Employee’s principal place of employment by more than fifty (50) miles.

6.             Non-Solicitation.  For a period beginning on the Effective Date and ending six (6) months after Employee ceases to be employed by the Company (the “Non-Solicitation Period”), Employee, directly or indirectly, whether as employee, owner, sole proprietor, partner, director, member, consultant, agent, founder, co-venturer or otherwise, will not: (i) solicit, induce or influence any person to leave employment with the Company; or (ii) directly or indirectly solicit business from any of the Company’s customers and users on behalf of any business that directly competes with the principal business of the Company; provided, however, that the Non-Solicitation Period shall end six (6) months after Employee ceases to be employed by the Company in the event Employee’s employment is terminated pursuant to an Involuntary Termination; provided further, however, that the Non-Solicitation Period shall end nine (9) months after Employee ceases to be employed by the Company in the event Employee’s employment is terminated pursuant to a Change of Control Termination.
