Such right shall not be conditional upon the Company having sufficient financing, at the time the right arises, to purchase the Shares; provided, however, in any event the Company is required to obtain such financing within the time period set forth in Section 2.2(b)(iii).

(iii) If the Company exercises its right of first refusal hereunder, the closing of the purchase of the Shares with respect to which such right has been exercised (the "First First Refusal Closing") shall take place within twenty-five (25) business days after the Company delivers the Response Notice to the Purchaser or, if later due to the need to determine the Fair Market Value of any non-cash consideration, within five (5) business days of such determination of the Fair Market Value of any non-cash consideration. Upon exercise of its right of first refusal, the Company and Purchaser shall be legally obligated to consummate the purchase and sale contemplated thereby and shall use their respective best efforts to secure any approvals required in connection therewith.

(iii) Transfer any Shares to any Person or 13D Group of which Purchaser has knowledge, after reasonable inquiry, will hold (including the Shares to be received in the transfer) more than ten percent (10%) of the Current Voting Power of the Company (other than through Open Market Transactions); provided, however, the restrictions set forth in this Section 2.2(d)(iii) shall not apply following a Strategic Alliance Agreement Termination that occurs prior to the third anniversary of the Closing Date.

(e) During the pendency of a Competitor Offer, (i) the restrictions on Transfer set forth in Section 2.2(a) and Section 2.2(d) hereof shall be suspended and (ii) the time period for the Company to provide a Response Notice pursuant to Section 2.2(b)(ii) shall be reduced to five (5) business days after receipt of the Transfer Notice and the time period for the First Refusal Closing shall be reduced to fifteen (15) business days after the Company delivers the Response Notice to Purchaser.

(f) Any attempted Transfer of any of the Total Shares by a Purchaser, a Purchaser Controlled Entity or any other person that is a party to this Agreement that is not in compliance with this Section 2.2, shall be null and void ab initio.

(b) During the Standstill Period, Purchaser, as a holder of Voting Stock, shall be present, in person or by proxy, (and shall cause any Purchaser Controlled Entity holding Voting Stock to be so present and shall use commercially reasonable efforts to cause its Affiliates holding Voting Stock and any 13D Group of which Purchaser or any Affiliate of Purchaser is a party and which holds Voting Stock to be so present) at all meetings of stockholders of the Company so that all shares of Voting Stock Beneficially Owned by such Persons may be counted for purposes of determining the presence of a quorum at such meetings.

(c) During the Standstill Period, in connection with any merger, consolidation or other reorganization which is approved by the Company's Board of Directors which is proposed to be accounted for as a pooling-of-interests transaction, Purchaser hereby covenants to enter into (and to cause any Purchaser Controlled Corporation to enter into and to use commercially reasonable efforts to cause any Affiliate of Purchaser and any 13D Group of which Purchaser or any Affiliate of Purchaser is a party to enter into) a standard pooling affiliate lock-up agreement if requested by the Company and if required to maintain pooling-of-interests treatment with respect to such transaction (based upon the recommendation of an independent accounting firm retained by either the Company or the potential acquiror of the Company).
