“FAIR MARKET VALUE” per share of Stock on any relevant date shall be determined in accordance with the following provisions:

(a) If the Stock is at the time listed on the Nasdaq National Market or the Nasdaq Capital Market, then the Fair Market Value shall be the closing selling price per share of Stock on the date in question, as such price is reported by the National Association of Securities Dealers on the Nasdaq National Market or the Nasdaq Capital Market and published in The Wall Street Journal.

III. ADMINISTRATION

(b) The Committee is hereby designated as the Plan Administrator and shall have full authority to administer the Plan, including authority to interpret and construe any provision of the Plan and to adopt such rules and procedures for administering the Plan as it may deem necessary in order to comply with the requirements of Section 423 of the Code.

This indemnity shall not apply, however, if (i) it is in the action, lawsuit, or proceeding that the individual is guilty of gross negligence or intentional misconduct in the performance of those duties; or (ii) the individual fails to assist the Company in defending against any such claim. The Company shall have the right to select counsel and to control the prosecution or defense of the suit. The Company shall not be obligated to indemnify any individual for any amount incurred through any settlement or compromise of any action unless the Company consents in writing to the settlement or compromise.

IV. PURCHASE PERIODS

(a) Stock shall be offered for purchase under the Plan through a series of successive purchase periods until such time as (i) the maximum number of shares of Stock available for issuance under the Plan shall have been issued pursuant to purchase rights granted under the Plan or (ii) the Plan shall have been sooner terminated in accordance with Article IX.

(b) Each purchase period shall have a duration of six (6) months. Purchase periods shall commence on the first day of April and October.

(c) The Participant shall be granted a separate purchase right for each purchase period in which he or she participates. The purchase right shall be granted on the first business day of the purchase period and shall be automatically exercised on the last business day of the purchase period.

3

(d) Under no circumstances shall any shares of Stock be issued hereunder, until such time as the Company shall have complied with all applicable requirements of the Securities Act of 1933, as amended, all applicable listing requirements of any securities exchange on which the Stock is listed and all other applicable requirements established by law or regulation.

(e) The acquisition of Stock through participation in the Plan for any purchase period shall neither limit nor require the acquisition of Stock by the Participant in any subsequent purchase period.

V. ELIGIBILITY AND PARTICIPATION

(a) Each individual who is an Eligible Employee of a Participating Company on the first day of any purchase period may begin participation in the Plan on the first day of any purchase period following the commencement of his or her employment with the Company or any other Participating Company.

(b) In order to participate in the Plan for a particular purchase period, an Eligible Employee must complete the enrollment forms prescribed by the Plan Administrator (including a stock purchase agreement and a payroll deduction authorization) and file such forms with the Plan Administrator (or its designee) during the specified enrollment period for that purchase period.

(c) The payroll deduction authorized by a Participant for purposes of acquiring Stock under the Plan may be any multiple of $10.00, up to a dollar maximum not in excess of 20% of the Base Salary paid to the Participant during the purchase period. The deduction rate so authorized shall continue in effect for the entire purchase period, unless the Participant shall, prior to the end of the purchase period for which the purchase right is in effect, change the rate by filing the appropriate form with the Plan Administrator (or its designee). The changed rate shall become effective as soon as practicable following the filing of such form. Payroll deductions, however, will automatically cease upon the termination of the Participant’s purchase right in accordance with Section VII(d) or (e) below.

VI. STOCK SUBJECT TO PLAN

(a) The Stock purchasable by Participants under the Plan shall, solely in the Board’s discretion, be made available from either authorized but unissued Stock or from reacquired Stock, including shares of Stock purchased on the open market. The total number of shares that may be issued under the Plan shall not exceed 2,850,000 shares (subject to adjustment under subparagraph (b) below). If any outstanding purchase right is terminated for any reason prior to its exercise, the shares allocable to the purchase right may again become subject to purchase under the Plan.

4

(b) In the event any change is made to the Stock purchasable under the Plan by reason of any stock dividend, recapitalization, stock split, reverse stock split, combination of shares, recapitalization or other change affecting the outstanding Stock as a class without the Company’s receipt of consideration, appropriate adjustments shall be made by the Plan Administrator to (i) the class and maximum number of shares issuable over the term of the Plan, (ii) the class and maximum number of shares purchasable per Participant under any one purchase right, and (iii) the class and number of shares and the price per share in effect under each purchase right at the time outstanding under the Plan.

VII. PURCHASE RIGHTS

Each Eligible Employee who participates in the Plan for a particular purchase period shall have the right to purchase Stock upon the terms and conditions set forth below and shall execute a purchase agreement embodying such terms and conditions and such other provisions (not inconsistent with the Plan) as the Plan Administrator may deem advisable.

(a) Purchase Price. The purchase price per share of Stock shall be 95% of the Fair Market Value of a share of Stock on the date the purchase right is exercised.

(b) Number of Purchasable Shares.

(i) The number of shares of Stock purchasable by a Participant upon the exercise of an outstanding purchase right shall be the number of whole shares obtained by dividing the amount collected from the Participant through payroll deductions during the purchase period for which such purchase right is outstanding, by the purchase price per share in effect for that purchase period. However, the maximum number of shares purchasable by any Participant during any one purchase period shall not exceed 1,000 shares (subject to adjustment under Section VI(b)). However, the Plan Administrator shall have the discretionary authority, exercisable prior to the start of any purchase period under the Plan, to increase or decrease the limitations to be in for the number of shares of Stock purchasable per Participant during that purchase period.

(ii) Under no circumstances shall purchase rights be granted the Plan to any Eligible Employee if such individual would, after the grant, own (within the meaning of Code Section 424(d)), or hold outstanding options or other rights to purchase, stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or any Corporate Affiliate. For this purpose an Eligible Employee’s ownership interest shall be determined in accordance with Code Section 424(d), which rules are as follows:

i. The Eligible Employee is treated as owning any stock owned, directly or indirectly, by:

(1) Brothers and sisters (whether by whole or half-blood);

(2) Spouse; and

(3) Lineal descendants and/or ancestors.

5

ii. Stock owned, directly or indirectly, by a corporation, partnership, estate, or trust is treated as owned proportionately by or for its stockholders, partners, or beneficiaries.

iii. Stock that can be acquired by the exercise of an option is treated as being owned by the Eligible Employee for purposes of determining the number of shares owned by the Eligible Employee, but not for purposes of determining the total number of shares of Stock outstanding. Options are taken into account for this purpose whether or not they are currently exercisable.

(c) Payment. Payment for the Stock purchased under the Plan shall be effected through the Participant’s authorized payroll deductions. Such deductions shall begin on the first pay day coincident with or immediately following the commencement date of the purchase period and shall terminate with the pay day ending with or immediately prior to the last business day of such purchase period. The amounts so collected shall be credited to the Participant’s individual account under the Plan, but no interest shall be paid on the balance from time to time outstanding in the account. The collected amounts shall not be required to be held in any segregated account or trust fund and may be commingled with the Company’s general assets and used for any corporate purpose.

(d) Termination of Purchase Rights.

(i) A Participant may terminate his or her outstanding purchase right under the Plan by filing the prescribed notification form with the Plan Administrator (or its designee) at least two business days before the last business day of any purchase period. No further payroll deductions shall be collected from the Participant with respect to such purchase right, and the Participant shall have the following election with respect to any payroll deductions made by such individual with respect to such purchase right: (A) have the Company refund those payroll deductions or (B) have such payroll deductions held for the purchase of shares at the end of the purchase period. If no such election is made, then such payroll deductions shall automatically be refunded at the end of such purchase period. Immediately following the refund or purchase of shares, the purchase right shall terminate.

(ii) The request for termination shall be irrevocable with respect to the particular purchase right to which it pertains, and the Participant may not subsequently rejoin the purchase period covered by such right.

(e) Termination of Service.

(i) Except as set forth in Paragraph VII(e)(ii) below, if a Participant ceases to be an Eligible Employee while his or her purchase right remains outstanding, then such purchase right shall immediately terminate, and all sums previously collected from the Participant during the purchase period in which such termination occurs shall be refunded (without interest) to the Participant.

6

(ii) Should the Participant die or become Permanently Disabled or should the Participant cease active employment by reason of a leave of absence taken in accordance with the Company’s leave of absence policy, then the Participant (or the person or persons to whom the rights of the deceased Participant under the Plan are transferred by will or by the laws of descent and distribution) shall have the election, exercisable up until the end of the purchase period in which the Participant dies or becomes Permanently Disabled or in which the leave of absence commences, to (i) withdraw all the funds credited to the Participant’s account at the time of his or her cessation of employment or at the commencement of such leave or (ii) have such funds held for the purchase of shares at the end of such purchase period. If no such election is made, then such funds shall automatically be held for the purchase of shares at the end of such purchase period. In no event, however, shall any further payroll deductions added to the Participant’s account following his or her cessation of employment or the commencement of such leave. Upon the Participant’s return to active employment of twenty (20) hours a week (x) within ninety (90) days following the commencement of such leave or (y) prior to the expiration of any longer period for which such Participant’s right to reemployment with the Company is guaranteed by statute or contract, his or her payroll deductions under the Plan shall automatically resume at the rate in effect at the time the leave began, unless the Participant withdraws from the Plan prior to his or her return. An individual who returns to active employment following a leave of absence that exceeds in duration the applicable (x) or (y) time period will no longer be an Eligible Employee for purposes of subsequent participation in the Plan, will receive a refund (without interest) of the payroll deductions that the Participant made during that purchase period with respect to such purchase right not previously exercised, and must accordingly re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before the first day of the new purchase period once he or she qualifies as an Eligible Employee.

(f) Stock Purchase. The Stock subject to the purchase right of each Participant (other than Participants whose payroll deductions have been refunded in accordance with Section VII(d) or (e) above) shall be automatically purchased on the Participant’s behalf on the last business day of the purchase period. The purchase shall be effected by applying the amount credited to each Participant’s account on the last business day of the purchase period to the purchase of whole shares of Stock (subject to the limitations on the maximum number of purchasable shares set forth in Section VII(b)) at the purchase price in effect for such purchase period. Any amount remaining in the Participant’s account after such application shall be refunded.

(g) Proration of Purchase Rights. Should the total number of shares of Stock that are to be purchased pursuant to outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and any amounts credited to the accounts of Participants shall, to the extent not applied to the purchase of Stock, be refunded to the Participants.

(h) Rights as Stockholder. A Participant shall have no rights as a stockholder of the Company with respect to shares covered by his or her outstanding purchase right under the Plan until the shares are actually purchased on the Participant’s behalf in accordance with Section VII(f). No adjustments shall be made for dividends, distributions or other rights for which the record date is prior to the date of such purchase.

7

(i) Assignability. No purchase right granted under the Plan shall be assignable or transferable by the Participant other than by will or by the laws of descent and distribution following the Participant’s death, and during the Participant’s lifetime the purchase right shall be exercisable only by the Participant.

(j) Notice of Disqualifying Disposition. A Participant must notify the Company if the Participant disposes of stock acquired pursuant to the Plan prior to the expiration of the holding periods required to qualify for long-term capital gains treatment on the sale proceeds.

(k) Merger or Liquidation of Company. In the event the Company or its stockholders enter into an agreement to dispose of all or substantially all of the assets or outstanding capital stock of the Company by means of a sale, merger, reorganization or similar transaction (other than a reorganization effected primarily to change the State in which the Company is incorporated) or in the event the Company is liquidated (a “Change in Control”), each outstanding purchase right shall automatically be exercised, immediately prior to the effective date of any Change in Control, by applying the payroll deductions of each Participant for the purchase period in which such Change in Control occurs to the purchase of whole shares of Stock at a purchase price per share equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of Stock on the first day of the purchase period in which such Change in Control occurs or (ii) the Fair Market Value per share of Stock immediately prior to the effective date of such Change in Control. However, the applicable limitation on the number of shares of Stock purchasable per Participant shall continue to apply to any such purchase. Any amount not applied to the purchase of Stock by reason of the Section VII(b) limitation on the maximum number of purchasable shares shall be refunded. The Company shall use its best efforts to provide at least ten (10) days’ prior written notice of the occurrence of any Change in Control, and Participants shall, following the receipt of such notice, have the right to terminate their outstanding purchase rights prior to the effective date of the Change in Control.

VIII. ACCRUAL LIMITATIONS

(a) No Participant shall be entitled to accrue rights to acquire Stock pursuant to any purchase right outstanding under the Plan if and to the extent such accrual, when aggregated with (i) rights to acquire Stock accrued under other purchase rights granted to the Participant under this Plan and (ii) similar rights accrued by the Participant under other employee stock purchase plans (within the meaning of Code Section 423) of the Company or its Corporate Affiliates, would otherwise permit such Participant to purchase more than $25,000 worth of Stock of the Company or any Corporate Affiliate (determined on the basis of the Fair Market Value of such stock on the date or dates such rights are granted to the Participant) for each calendar year such rights are at any time outstanding.

(b) For purposes of applying the accrual limitations of Section VIII(a), the right to acquire Stock pursuant to each purchase right granted under the Plan shall accrue as follows:

8

(i) The right to acquire Stock under each such purchase right shall accrue when the purchase right first becomes exercisable on the last business day of the purchase period for which such right is granted.

(ii) To the extent the Participant’s purchase right does not, by reason of the Section VIII(a) limitations, accrue on the last business day of the particular purchase period for which such right is granted, then the payroll deductions that the Participant made during that purchase period with respect to such purchase right shall be refunded.

(c) In the event there is any conflict between the provisions of this Article VIII and one or more provisions of the Plan or any instrument issued thereunder, the provisions of this Article VIII shall be controlling.

IX. AMENDMENT AND TERMINATION

The Board may from time to time alter, amend, suspend or discontinue the Plan to become effective immediately following the close of a purchase period; provided, however, the Plan may be amended or terminated immediately upon Board action, if and to the extent necessary to assure that the Company will not recognize, for financial reporting purposes, any compensation expense in connection with the shares of Stock offered for purchase under the Plan, should the financial accounting rules applicable to the Plan at the Effective Date be subsequently revised so as to require the Company to recognize compensation expense in the absence of such amendment or termination. The Board may not, without the approval of the Company’s stockholders, increase the number of shares issuable under the Plan (provided, however, the Plan Administrator shall have the authority to effect adjustments pursuant to Section VI(b) without stockholder approval).
