6. Obligations of the Company. The Company shall use its best efforts and shall exercise all authority under applicable law to cause to be nominated for election and cause to be elected or appointed, as the case may be, as directors of the Company, a slate of directors consisting of individuals meeting the requirements of Section 2. The Company will not, by any voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all of the provisions of this Agreement and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of the Investors hereunder against impairment. Each Shareholder hereby agrees to vote, cause to be voted or sign a written consent with respect to all of its shares in favor of a slate of directors consisting of individuals meeting the requirements of Section 2.

7. Vacancies; Removal.

In any such event, the Board of Directors shall solicit the vote of the Shareholders entitled to remove such director in order to effect such removal. In addition, in the event that the person serving as the CEO Director ceases to serve as the Company’s Chief Executive Officer or President, as the case may be, the Shareholders agree to vote all outstanding shares of Stock owned or controlled by them for the removal of such CEO Director at the request of a majority of the Board of Directors (excluding the CEO Director).

6

such transferee’s signature appeared on the signature pages hereto.

9

acquiescence therein, or of any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring.
