The number of Restricted Stock Units that become vested as of a specified date pursuant to Section 2 above will be settled within thirty-one (31) days after such date and the number of Restricted Stock Units that become vested as of an earlier date pursuant to Section 3 because the Participant incurs a Termination of Service due to Involuntary Termination Without Cause, death or Disability will be settled within thirty-one (31) days after such date or if later, within the period from [February 1, [year] to March 15, [year]]; provided, that the Participant shall not be permitted, directly or indirectly, to designate the taxable year of the payment.

10.Restrictive Covenants. In the event that the Company determines that the Participant has violated the terms of any secrecy, confidentiality, noncompetition, no-solicit, no-hire or other restrictive covenants or clauses contained in any agreement with the Company and/or one or more Subsidiaries including but not limited to any Restrictive Covenants and Confidentiality Agreement (even if such covenants, clauses or agreements are held invalid or unenforceable), then (a) any unvested Restricted Stock Units and any shares of Common Stock or cash payments arising from vested Restricted Stock Units that have not yet been delivered to the Participant shall be immediately and automatically forfeited and rescinded upon such violation and (b) if any other Restricted Stock Units have vested after such violation or within two (2) years prior to such violation, then (without regard to tax consequences) the Participant agrees to return the previously received cash payments, and, if applicable, the previously received corresponding shares of Common Stock to the Company or if the Participant has sold or disposed of such shares, the Participant agrees to immediately pay the Company an amount equal to the fair market value of such shares at the time of such sale or disposition. Subject to applicable law, the Company and its Subsidiaries have the right to offset such payment amount against any amounts otherwise owed to the Participant by the Company or a Subsidiary (including, but not limited to, wages or other compensation, vacation pay, fringe benefits or pursuant to any other compensatory arrangement); provided, that any payment that constitutes nonqualified deferred compensation subject to Section 409A of the Code, as determined by the Company, shall be subject to offset only to the extent such offset would not give rise to a failure to comply with Section 409A of the Code. Notwithstanding the foregoing, nothing under this Section shall limit the Company’s or its Subsidiaries’ remedies under any such agreements containing secrecy, confidentiality, noncompetition, no-solicit and/or no-hire covenants or clauses or otherwise against the Participant for violations thereof.

11.Forfeiture Procedures. In the event of the forfeiture of any Restricted Stock Units, such forfeiture shall be automatic and without further act by the Participant or the Company, and neither the Company nor any Subsidiary will have any further obligation to the Participant under this Restricted Stock Unit Agreement with respect to, and the Participant shall not have any further interest in, such Restricted Stock Units. Notwithstanding the foregoing, if requested by the Company (or its agent), the Participant shall execute such documents (including, without limitation, a power of attorney in favor of the Company) and take such other action deemed necessary or desirable by the Company to evidence such forfeiture.

12.Tax Matters (Withholding). The Participant shall pay or make provision for payment to the Company or a Subsidiary, as applicable, through payroll withholding (which the Participant hereby authorizes), other withholding or other means acceptable to the Committee and permissible under the Plan (including withholding of shares of Common Stock), of the amount necessary to satisfy any federal, state or local withholding requirements applicable to any taxable event arising in connection with the Restricted Stock Units (including, without limitation, vesting and settlement events). If other satisfactory withholding arrangements have not been made by the Participant and unless otherwise provided by the Committee, the Company shall retain and withhold from the cash payment or, if applicable, the shares of Common Stock otherwise deliverable to the Participant upon vesting and/or settlement of the Restricted Stock Units such cash amount necessary to satisfy the applicable tax withholding or, if applicable, such number of shares with a value sufficient to satisfy the statutory minimum required withholding amount and any remaining amount shall be otherwise satisfied as described above. The determination of the withholding amounts due shall be made by the Company and/or its Subsidiaries and shall be binding upon the Participant. The Company shall not be required to deliver any shares of Common Stock (if applicable) unless the Participant has made acceptable arrangements to satisfy any such withholding requirements. Nothing in this Section shall be construed to impose on the Company a duty to withhold where applicable law does not require such withholding.

NOTWITHSTANDING ANY ACTION THAT THE COMPANY OR A SUBSIDIARY TAKES WITH RESPECT TO ANY TAX-RELATED WITHHOLDING, THE PARTICIPANT ACKNOWLEDGES THAT THE PARTICIPANT IS AND REMAINS RESPONSIBLE FOR AND IS ADVISED TO CONSULT WITH THE PARTICIPANT’S OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THE PARTICIPANT THAT MAY ARISE IN CONNECTION WITH THE RESTRICTED STOCK UNITS. THE COMPANY DOES NOT MAKE ANY REPRESENTATIONS OR WARRANTIES REGARDING THE TREATMENT OF ANY TAXES IN CONNECTION WITH THE RESTRICTED STOCK UNITS.

13.Adjustments. Subject to the Plan, in the event of a reorganization, recapitalization, stock split, stock dividend, extraordinary dividend, spin-off, combination of shares, merger, consolidation or similar transaction or other change in corporate capitalization affecting the Common Stock, equitable adjustments and/or substitutions, as applicable, will be made to the outstanding Restricted Stock Units by the Committee to prevent the dilution or enlargement of rights. The Committee also will make adjustments in its discretion to eliminate any resulting fractional shares or Restricted Stock Units.

The existence of the Restricted Stock Units does not affect in any way the authority of the Company and its stockholders to exercise their corporate rights and powers, including, but not by way of limitation, the right of the Company to authorize any adjustment, reclassification, reorganization, or other change in its capital or business structure, any merger or consolidation of the Company, the dissolution or liquidation of the Company, the issuance of securities with preference ahead of or affecting the Common Stock, or any sale or transfer of all or any part of its business or assets.

14.Nature of Arrangement. The Participant’s rights under this Restricted Stock Unit Agreement are only contractual in nature unsecured by any assets of the Company or any Subsidiary. The Company is not required to segregate any specific funds, assets or other property from its general assets with respect to the Restricted Stock Units. The Participant shall have no rights under this Restricted Stock Unit Agreement other than as an unsecured general creditor of the Company. To the extent that this Restricted Stock Unit Agreement provides for a deferral of compensation within the meaning of Section 409A of the Code, this Restricted Stock Unit Agreement is intended to comply with Section 409A of the Code and shall be interpreted consistent with such intent. References in this Restricted Stock Unit Agreement to Section 409A of the Code also shall be deemed to include reference to applicable regulations or other authoritative guidance thereunder, and any amendments or successor provisions to such section, regulations or guidance. To the extent applicable, each and every payment made pursuant to this Restricted Stock Unit Agreement shall be treated as a separate payment and not as one of a series of payments treated as a single payment for purposes of Section 409A of the Code. Notwithstanding the foregoing, the Company does not guarantee to the Participant that this Restricted Stock Unit Agreement is exempt from or complies with Section 409A of the Code, and shall not indemnify or hold harmless the Participant with respect to any tax consequences that arise from any such failure to meet an exemption under or comply with Section 409A of the Code.

15.Securities Laws.Notwithstanding any provision herein to the contrary or in the Plan, if the Restricted Stock Units are to be settled in shares of Common Stock, the Company shall be under no obligation to issue any shares of Common Stock to the Participant pursuant to this Restricted Stock Unit Agreement unless and until the Company has determined that such issuance is either exempt from registration, or is registered, under the Securities Act of 1933, as amended, and is either exempt from registration and qualification, or is registered or qualified, as applicable, under all applicable state securities or “blue sky” laws. Nothing in this Restricted Stock Unit Agreement shall be construed to obligate the Company at any time to file or maintain a registration statement under the Securities Act of 1933, as amended, or to effect similar compliance under any applicable state laws with respect to any Common Stock that may be issued pursuant to this Restricted Stock Unit Agreement. The Company may require that the Participant make such representations and agreements and furnish such information as the Company deems appropriate to assure compliance with applicable legal and regulatory requirements.
