(“RF Monolithics” or the “Company”) and its Subsidiaries, and (ii) to furnish maximum incentive to those persons to improve operations and increaseprofits and to strengthen the mutuality of interest between those persons and RF Monolithics’ stockholders by providing them restricted stock, restricted stock units and other stock and cash incentives. 

2. **Administration**. The Plan will be administered by the Compensation Committee (the “Committee”) of the RF Monolithics Board ofDirectors consisting of two or more directors as the Board may designate from time to time, each of whom shall satisfy such requirements as: 

(a) the Securities and Exchange Commission may establish for administrators acting under plans intended to qualify for exemption under Rule 16b-3 or its successor under the Securities Exchange Act of 1934 (the “ExchangeAct”); 

(b) NASDAQ may establish pursuant to its rule-making authority; and 

(c) the Internal Revenue Service may establish for outside directors acting under plans intended to qualify for exemption under Section 162(m)of the Internal Revenue Code of 1986, as amended (the “Code”). 

The Committee shall have the discretionary authority to construe and interpretthe Plan and any benefits granted thereunder, to establish and amend rules for Plan administration, to change the terms and conditions of options and other benefits at or after grant, to correct any defect or supply any omission or reconcile anyinconsistency in the Plan or in any option or other benefit granted under the Plan, and to make all other determinations which it deems necessary or advisable for the administration of the Plan. The determinations of the Committee shall be made inaccordance with their judgment as to the best interests of RF Monolithics and its stockholders and in accordance with the purposes of the Plan and need not otherwise be uniform or consistent. Any determination of the Committee under the Plan may bemade without notice or meeting of the Committee, in writing signed by all the Committee members. The Committee may authorize one or more officers of the Company to select employees to participate in the Plan and to determine the number of shares ofrestricted stock, restricted stock units and other awards to be granted to such participants, except with respect to awards to officers subject to Section 16 of the Exchange Act or officers who are, or who are reasonably expected to be,“covered employees” within the meaning of Section 162(m) of the Code (“Covered Employees”) and any reference in the Plan to the Committee shall include such officer or officers. 

3. **Participants**. Participants may consist of all employees of RF Monolithics and its Subsidiaries. Any corporation or other entity in which a50% or greater interest is at the time directly or indirectly owned by RF Monolithics and which RF Monolithics consolidates for financial reporting purposes shall be a “Subsidiary” for purposes of the Plan. Designation of a participant inany year shall not require the Committee to designate that person to receive a benefit in any other year or to receive the same type or amount of benefit as granted to the participant in any other year or as granted to any other participant in anyyear. The Committee shall consider all factors that it deems relevant in selecting participants and in determining the type and amount of their respective benefits. 

4. **Types of Benefits**. Benefits under the Plan may consist of Restricted Stock, Restricted Stock Units, Performance Cash Awards, Management Incentive Awards and Other Stock or Cash Awards, all as describedbelow. Anything herein to the contrary notwithstanding, all equity-based awards hereunder shall be authorized under a shareholder-approved plan, such as the Company’s 2006 Equity Incentive Plan, as a condition to being authorized hereunder.

 

5. **Restricted Stock and Restricted Stock Units.** Restricted Stock and Restricted Stock Unitsmay be awarded or sold to participants under such terms and conditions as shall be established by the Committee. Restricted Stock provides participants the rights to receive shares after vesting in accordance with the terms of such grant upon theattainment of certain conditions specified by the Committee. Restricted Stock Units provide participants the right to receive shares at a future date after vesting in accordance with the terms of such grant upon the attainment of certain conditionsspecified by the Committee. Restricted Stock and Restricted Stock Units shall be subject to such restrictions as the Committee determines, including, without limitation, any of the following: 

(a) a prohibition against sale, assignment, transfer, pledge, hypothecation or other encumbrance for a specified period; 

(b) a requirement that the holder forfeit (or in the case of shares or units sold to the participant, resell to RF Monolithics at cost) such sharesor units in the event of termination of employment during the period of restriction; or 

(c) the attainment of performance goalsincluding without limitation those described in section 9 hereof. 

All restrictions shall expire at such times as the Committee shallspecify. In the Committee’s discretion and subject to other legal and contractual limitations, participants may be entitled to dividends or dividend equivalents on awards of Restricted Stock or Restricted Stock Units. 

The shares reserved for issuance and each of the limitations set forth above shall be subject to adjustment in accordance with section 11 hereof.

6. **Performance Cash Awards**. The Committee shall designate the participants to whom cash incentives based upon performance(“Performance Cash Awards”) are to be awarded and determine the amount of the award and the terms and conditions of each such award; provided the stated performance period will not be less than 3 months. Each Performance Cash Awardshall entitle the participant to a payment in cash upon the attainment of performance goals and other terms and conditions specified by the Committee. 

Notwithstanding the satisfaction of any performance goals, the amount to be paid under a Performance Cash Award may be adjusted by the Committee on the basis of such further consideration as the Committee in its solediscretion shall determine. However, the Committee may not, in any event, increase the amount earned under Performance Cash Awards upon satisfaction of any performance goal by any participant who is a Covered Employee (as defined in section 2 above)and the maximum amount earned by a Covered Employee in any calendar year may not exceed the amount specified in section 6 below. The Committee may, in its discretion, substitute actual shares of common stock for the cash payment otherwise requiredto be made to a participant pursuant to a Performance Cash Award. 

7. **Management Incentive Awards**. The Committee may designateRF Monolithics participants who are eligible to receive a monetary payment in any fiscal year based on a percentage or a fixed amount of an incentive pool not to exceed an aggregate amount equal to the greater of (i) 5% of RF Monolithics’consolidated operating net income for the fiscal year or (ii) 2.5% of RF Monolithics’ sales for the fiscal year, subject as to clause (ii) to a maximum of $1,500,000.

As soon as possible after the determination of RF Monolithics’ performance during each fiscalquarter of a Plan year, the Committee shall calculate the participant’s incentive payment based upon the terms established at the beginning of the fiscal quarter or year. Adjustments to this calculation may be made in the sole discretion of theCommittee. In no event may the portion of the incentive pool allocated to a participant who is a Covered Employee (as defined in section 2 above) be increased in any way, including as a result of the reduction of any other participant’sallocated portion. 

8. **Other Stock or Cash Awards**. In addition to the incentives described in sections 5 through 7 above, theCommittee may grant other incentives payable in cash or in common stock under the Plan as it determines to be in the best interests of RF Monolithics and subject to such other terms and conditions as it deems appropriate; provided an outright grantof stock will not be made unless it is offered in exchange for cash compensation that has otherwise already been earned by the recipient. 

9. **Performance Goals**.

In all other respects, Performance Criteriashall be calculated in accordance with the Company’s financial statements (including without limitation the Company’s “consolidated operating net income” as defined in section 7), generally accepted accounting principles, orunder an objective methodology established by the Committee prior to the issuance of an award which is consistently applied and identified in the audited financial statements, including footnotes, or the Management’s Discussion and Analysissection of the Company’s annual or quarterly report. However, the Committee may not in any event increase the amount of compensation payable to a Covered Employee upon the attainment of a performance goal.
