Upon such a transfer, the person acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by the person acquiring the Shares.

Company Right to Purchase. For 30 days following its receipt of such Transfer Notice, the Company shall have the option to purchase all or part of the Offered Shares at the price and upon the terms set forth in the Transfer Notice.

If all of the Shares proposed to be Transferred in the Notice are not purchased by the Company and/or its assignee(s) as provided in this [Section 4], then the Holder may sell or otherwise Transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other Transfer is consummated within one hundred twenty (120) days after the date of the Notice and provided further that any such sale or other Transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this [Section 4] shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not Transferred to the Proposed Transferee within such 120-day period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal as provided herein before any Shares held by the Holder may be sold or otherwise Transferred.

Neither the Plan, any Option nor any Stock Purchase Right shall confer upon a Holder any right with respect to continuing the Holder’s employment or consulting relationship with the Company, nor shall they interfere in any way with the Holder’s right or the Company’s right to terminate such employment or consulting relationship at any time, with or without cause.

Upon the occurrence of a Fundamental Change, each Holder shall have the option, during the period commencing on the date the applicable Fundamental Change Notice (as defined below) is mailed to Holders of the Series B Preferred Stock and ending at the Close of Business on the 45th Business Day thereafter (the “Fundamental Change Redemption Date”), to require the

Landlord’s Recapture Right. Notwithstanding anything to the contrary contained in this Paragraph 22, in the event that Tenant contemplates a Transfer, Tenant shall give Landlord notice (the “Intention to Transfer Notice”) of such contemplated Transfer (whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined); provided, however, that Landlord hereby acknowledges and agrees that Tenant shall have no obligation to deliver an Intention to Transfer Notice hereunder, and Landlord shall have no right to recapture space with respect to # a Transfer of up to the entirety of two (2) full floors (except any such Transfer for rentable square footage that when combined with the rentable square footage of any prior Transfer would exceed the equivalent of two (2) full floors) for less than substantially the remainder of the Term, or # a Permitted Transfer. The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such contemplated Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Paragraph 22.5 in order to allow Landlord to elect to recapture the Contemplated Transfer Space for the remainder of the Lease Term. Thereafter, Landlord shall have the option, by giving written notice to Tenant (the “Recapture Notice”) within thirty (30) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Tenant shall have fifteen (15) Business Days after receipt of the Recapture Notice to withdraw the Contemplated Transfer Space which triggered the Recapture Notice. Should the Contemplated Transfer Space be withdrawn, no recapture shall occur and Tenant shall remain in possession. Any recapture under this Paragraph 22.5 shall cancel and terminate (or suspend if not for the remainder of the Lease Term) this Lease with respect to the Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, # Landlord shall install, on a commercially reasonable basis, any corridor and/or demising wall which is required as a result of a recapture by Landlord pursuant to the terms hereof, # the Rent reserved herein shall be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises; and # this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner, to recapture the Contemplated Transfer Space under this Paragraph 22.5, then, subject to the other terms of this Paragraph 22, for a period of six (6) months (the “Six Month Period”) commencing on the last day of such thirty (30) day period, Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any Transfer made during the Six Month Period; provided however, that any such Transfer shall be subject to the remaining terms of this Paragraph 22. If such a Transfer is not so consummated within the Six Month Period (or if a Transfer is so consummated, then upon the expiration of the term of any Transfer of such Contemplated Transfer Space consummated within such Six Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this Paragraph 22.5.

Landlord’s Termination Right. In the event of any of the following circumstances, Landlord may elect either to terminate this Lease or to perform Landlord’s Restoration Work, as more particularly described in Paragraph 25.1:

The Company and its transfer agent on its behalf are hereby authorized # subject to the provisions of [Section 4(b)], to decline to register any transfer of securities if such transfer would constitute a violation or breach of this Agreement and # to imprint on any certificate representing Shares a legend describing the restrictions contained herein or customarily notate within the transfer agent records if shares are held in book entry form, substantially in the form as follows: “THE SHARES REPRESENTED HEREBY MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN COMPLIANCE WITH THE TERMS OF A LOCK-UP AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER OF THE SHARES (OR THE PREDECESSOR IN INTEREST TO THE SHARES). THE SECRETARY OF THE COMPANY WILL, UPON WRITTEN REQUEST, FURNISH A COPY OF SUCH AGREEMENT TO THE HOLDER HEREOF WITHOUT CHARGE.” Subject to the provisions of [Section 4(b)], the Holder hereby authorizes the Company and its transfer agent, during the Lock-Up Period, to place stop-transfer restrictions on the stock register and other records relating to the Shares.
