6.Company Acquisition of Covered Securities Upon an Impermissible Transfer Event.

(a)CMB agrees that neither of CMB nor CCB, shall at any time during the Interim Period (i) Transfer any Securities to anyone other than the Company, (ii) instruct, or seek to cause the Transfer of, any Securities to anyone other than the Company or (iii) authorize or direct any lien to be

placed on any of the Securities that would not be released by the Payoff Letter or automatically upon the consummation of the Purchase without any additional action of CMB or the Company (any of the foregoing, any “Impermissible Transfer Event”). Notwithstanding the foregoing, the Company agrees that each of (x) any Transfer resulting from a merger, tender or exchange offer, reorganization or other fundamental transaction involving the Securities approved by the Board of Directors of the Company and (y) any planning, discussions or negotiations with any person by CMB or CCB during the Interim Period that is related to the Securities shall not in and of itself constitute an Impermissible Transfer Event.

Following implementation of the Remedial Transfer Instructions by the Transfer Agent, the Company shall, subject to any obligation that the Company may have to return the shares pursuant to this Agreement, acquire valid and unencumbered title to the Covered Securities (a “Remedial Transfer”). Nothing in this Agreement shall be interpreted to limit or affect CMB’s right following the occurrence of such Remedial Transfer to Dispute pursuant to Section 5.7 whether an Impermissible Transfer Event has actually occurred and whether such Remedial Transfer should be revoked and the Covered Securities transferred back to CMB. If a Dispute is resolved in favor of CMB and a determination is made that no Impermissible Transfer Event occurred, the Company shall immediately transfer the Covered Securities back to CMB and instruct the Transfer Agent to register the Covered Securities in the name of CMB; provided, that if the Closing occurs any such Dispute initiated by CMB shall be withdrawn and the Company shall remain the owner of the Covered Securities without any further action by the Company or CMB. In the event of a Dispute, until the Dispute has been resolved or withdrawn, Company shall not take any action to cancel or Transfer the Covered Securities. The Parties agree that upon receipt of the Unilateral Company Notice delivered pursuant to this Section 1.6(b), ASW may release each of the Remedial Transfer Instructions and the Payoff Letter to the Company and that CMB will have no cause of action against ASW for doing so.

(i)The arbitrators shall issue a reasoned award in writing.
