The maximum duration of an Offer Period shall be six (6) months. Initially, the Plan shall be implemented through consecutive Offer Periods of six (6) months' duration commencing each February 15 and August 15 following the Effective Date (except that the initial Offer Period under the Plan shall commence on the later to occur of (i) February 15, 2012 or (ii) the date stockholder approval of the Plan shall have been received by the Company, and shall end on August 14, 2012).

(b)    A Participant shall be granted a separate option for each Offer Period in which he or she participates. The option shall be granted on the Enrollment Date and shall be automatically exercised on the last day of the Offer Period.

(a)    An eligible Employee may become a Participant in the Plan by completing a subscription agreement

authorizing payroll deductions in the form of Exhibit A to this Plan (or in such other form or procedure the Administrator determines for evidencing elections to participate) and filing it with the designated payroll office of the Company at least ten (10) business days prior to the Enrollment Date for the Offer Period in which such participation will commence, unless a later time for filing the subscription agreement is set by the Administrator for all eligible Employees with respect to a given Offer Period.

(b)    Payroll deductions for a Participant shall commence with the first partial or full payroll period beginning on the Enrollment Date and shall end on the last complete payroll period during the Offer Period, unless sooner terminated by the Participant as provided in Section 10.

(a)    At the time a Participant files a subscription agreement, the Participant shall elect to have payroll deductions made during the Offer Period in amounts between one percent (1%) and not exceeding ten percent (10%) of the Compensation which the Participant receives during the Offer Period.

(b)    All payroll deductions made for a Participant shall be credited to the Participant's account under the Plan and will be withheld in whole percentages only. A Participant may not make any additional payments into such account.

(c)    A Participant may discontinue participation in the Plan as provided in Section 10, or may increase or decrease the rate of payroll deductions during the Offer Period by completing and filing with the Company a change of status notice in the form of Exhibit B to this Plan authorizing an increase or decrease in the payroll deduction rate. Any increase or decrease in the rate of a Participant's payroll deductions shall be effective with the first full payroll period commencing ten (10) business days after the Company's receipt of the change of status notice unless the Company elects to process a given change in participation more quickly. A Participant's subscription agreement (as modified by any change of status notice) shall remain in effect for successive Offer Periods unless terminated as provided in Section 10. The Administrator shall be authorized to limit the number of payroll deduction rate changes during any Offer Period.

d)    Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) herein, a Participant's payroll deductions shall be decreased to 0%. Payroll deductions shall recommence at the rate provided in such Participant's subscription agreement, as amended, at the time when permitted under Section 423(b)(8) of the Code and Section 3(b) herein, unless such participation is sooner terminated by the Participant as provided in Section 10.

(a)    On the Enrollment Date, each Participant shall be granted an option to purchase (at the applicable Purchase Price) up to a maximum of one thousand five hundred (1,500) shares of the Common Stock, subject to adjustment as provided in Section 18 hereof; provided that such option shall be subject to the limitations set forth in Sections 3(b), 6 and 12 hereof. Exercise of the option shall occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10, and the option, to the extent not exercised, shall expire on the last day of the Offer Period.

(b)    The maximum aggregate number of shares that all Participants shall be able to purchase during an Offer Period shall be the remaining Shares available under the Plan as of the Enrollment Date for that Offer Period.

(c)    In accordance with Section 423(b)(5) of the Code, all Employees granted an option under the Plan shall have the same rights and privileges.

(a)    A Participant may either (i) withdraw all but not less than all the payroll deductions credited to the Participant's account and not yet used to exercise the Participant's option under the Plan or (ii) terminate future payroll deductions, but allow accumulated payroll deductions to be used to exercise the Participant's option under the Plan at any time by giving written notice to the Company in the form of Exhibit B to this Plan. If the Participant elects withdrawal alternative (i) described above, all of the Participant's payroll deductions credited to the Participant's account will be paid to such Participant as promptly as practicable after receipt of notice of withdrawal, such Participant's option for the Offer Period will be automatically terminated, and no further payroll deductions for the purchase of shares will be made during the Offer Period. If the Participant elects withdrawal alternative (ii) described above, no further payroll deductions for the purchase of shares will be made during the Offer Period, all of the Participant's payroll deductions credited to the Participant's account will be applied to the exercise of the Participant's option on the next Exercise Date, and after such Exercise Date, such Participant's option for the Offer Period will be automatically terminated. If a Participant withdraws from an Offer Period, payroll deductions will not resume at the beginning of the succeeding Offer Period unless the Participant delivers to the Company a new subscription agreement.

(b)    Upon termination of a Participant's employment relationship (as described in Section 2(l)) at a time more than three (3) months from the next scheduled Exercise Date, the payroll deductions credited to such Participant's account during the Offer Period but not yet used to exercise the option will be returned to such Participant or, in the case of his/her death, to the person or persons entitled thereto under Section 14, and such Participant's option will be automatically terminated. Upon termination of a Participant's employment relationship (as described in Section 2(l)) within three (3) months of the next scheduled Exercise Date, the payroll deductions credited to such Participant's account during the Offer Period but not yet used to exercise the option will be applied to the purchase of Common Stock on the next Exercise Date, unless the Participant (or in the case of the Participant's death, the person or persons entitled to the Participant's account balance under Section 14) withdraws from the Plan by submitting a change of status notice in accordance with subsection (a) of this Section 10. In such a case, no further payroll deductions will be credited to the Participant's account following the Participant's termination of employment and the Participant's option under the Plan will be automatically terminated after the purchase of Common Stock on the next scheduled Exercise Date.

(a)    The maximum number of shares of Common Stock which shall be made available for sale under the Plan shall be one million (1,000,000) shares, subject to adjustment upon changes in capitalization of the Company as provided in Section 18. If the Administrator determines that on a given Exercise Date the number of shares with respect to which options are to be exercised may exceed (x) the number of shares then available for sale under the Plan or (y) the number of shares available for sale under the Plan on the Enrollment Date(s) of one or more of the Offer Periods in which such Exercise Date is to occur, the Administrator may make a pro rata allocation of the shares remaining available for purchase on such Enrollment Dates or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine to be equitable, and shall either continue all Offer Periods then in effect or terminate any one or more Offer Periods then in effect pursuant to Section 19, below.

(b)    A Participant will have no interest or voting right in shares covered by the Participant's option until such shares are actually purchased on the Participant's behalf in accordance with the applicable provisions of the Plan. No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date of such purchase.

(c)    Shares to be delivered to a Participant under the Plan will be registered in the name of the Participant or in the name of the Participant and his or her spouse.

(a)    Each Participant will file a written designation of a beneficiary who is to receive any shares and cash, if any, from the Participant's account under the Plan in the event of such Participant's death. If a Participant is married and the

designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective.

(b)    Such designation of beneficiary may be changed by the Participant (and the Participant's spouse, if any) at any time by written notice. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living (or in existence) at the time of such Participant's death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Administrator), the Administrator shall deliver such shares and/or cash to the spouse (or domestic partner, as determined by the Administrator) of the Participant, or if no spouse (or domestic partner) is known to the Administrator, then to the issue of the Participant, such distribution to be made per stirpes (by right of representation), or if no issue are known to the Administrator, then to the heirs at law of the Participant determined in accordance with Section 27.

(a)    Adjustments Upon Changes in Capitalization. Subject to any required action by the stockholders of the Company, the Reserves, the Purchase Price, the maximum number of shares that may be purchased in any Offer Period, as well as any other terms that the Administrator determines require adjustment shall be proportionately adjusted for (i) any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, (ii) any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company, or (iii) as the Administrator may determine in its discretion, any other transaction with respect to Common Stock to which Section 424(a) of the Code applies; provided, however that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator and its determination shall be final, binding and conclusive. Except as the Administrator determines, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason hereof shall be made with respect to, the Reserves and the Purchase Price.

(b)    Corporate Transactions. In the event of a proposed Corporate Transaction, each option under the Plan shall be assumed by such successor corporation or a parent or subsidiary of such successor corporation, unless the Administrator, in the exercise of its sole discretion and in lieu of such assumption, determines to shorten the Offer Period then in progress by setting a new Exercise Date (the “New Exercise Date”). If the Administrator shortens the Offer Period then in progress in lieu of assumption in the event of a Corporate Transaction, the Administrator shall notify each Participant in writing at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant's option has been changed to the New Exercise Date and that either:

(i)    the Participant's option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offer Period as provided in Section 10; or

(ii)    the Company shall pay to the Participant on the New Exercise Date an amount in cash, cash equivalents, or property as determined by the Administrator that is equal to the difference in the Fair Market Value of the shares subject to the option and the Purchase Price due had the Participant's option been exercised automatically under Subsection (b)(i) above.

For purposes of this Subsection, an option granted under the Plan shall be deemed to be assumed if, in connection with the Corporate Transaction, the option is replaced with a comparable option with respect to shares of capital stock of the successor corporation or Parent thereof. The determination of option comparability shall be made by the Administrator prior to the Corporate Transaction and its determination shall be final, binding and conclusive on all persons.

(a)    The Administrator may at any time and for any reason terminate or amend the Plan. Except as provided in Section 18, no such termination can affect options previously granted, provided that the Plan or any one or more Offer Periods may be terminated by the Administrator on any Exercise Date or by the Administrator establishing a new Exercise Date with respect to any Offer Period (and/or any Purchase Period, if applicable) then in progress if the Administrator determines that the termination of the Plan or such one or more Offer Periods is in the best interests of the Company and its stockholders. Except as provided in Section 18 and this Section 19, no amendment may make any change in any option theretofore granted which adversely affects the rights of any Participant without the consent of affected Participants. To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other Applicable Law), the Company shall obtain stockholder approval in such a manner and to such a degree as required.

(b)    Without stockholder consent and without regard to whether any Participant rights may be considered to have been “adversely affected,” the Administrator shall be entitled to limit the frequency and/or number of changes in the amount withheld during Offer Periods, implement and/or change the length of Purchase Periods within any Offer Period, determine the length of any future Offer Period, determine whether future Offer Periods shall be consecutive or overlapping, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable foreign jurisdictions, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company's processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with amounts withheld from the Participant's Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable and which are consistent with the Plan.
