Assignment; Right of First Offer. 23.1 Right of First Offer. Subject to the provisions of this section 23, the Notes may not be assigned to any person that (so long as no Event of Default described in any of Sections 11.1(a), (b), (d), (e), or (f) has occurred in which event the consent of the Company shall not be required) is a Competitor (provided that this limitation shall be waived with respect to a proposed transferee if the Company determines in its reasonable discretion that such proposed transferee does not then compete with the Company or any entity controlled by the Company) or not a U.S. Qualified Person at the time of assignment, provided that the Company shall have a right of first offer on such assignment as follows: (a) First Offer. (i) If the holder proposes to sell or otherwise transfer the Notes or any portion thereof it holds at such time (collectively, the "Transfer Interests") to any third party other than an Affiliate of such holder (other than a sale or transfer in -24- connection with a Demand Registration or Piggy-Back Registration under the Rights Agreement), the holder is required to first notify the Company, by delivering to the Company a written notice ("Sale Notice") in accordance with Section 19, stating the holder's bona fide intention to sell or otherwise transfer the Transfer Interests. The Company shall have the exclusive right, for a period of thirty (30) days from its receipt of the Sale Notice, to make an offer to purchase the Transfer Interests at a price to be proposed by the Company. (ii) Subject to Section 23.1(c) below, if either (x) the Company does not deliver to the holder written notice of an offer to purchase the Transfer Interests ("Purchase Notice") within thirty (30) days after the Company's receipt of the Sale Notice, or (y) the holder has rejected the Company's offer, the holder shall be entitled to sell the Transfer Interests at a price which is no less than ninety percent (90%) of the last price offered by the Company for the Transfer Interests (the "Last Offer Price"), to any third party that is not an Affiliate of the holder at any time during the period of nine (9) months following the date of delivery of the Sale Notice by the holder to the Company, without the obligation to provide any further offers or notices to the Company. (b) Second Offer. (i) If the holder proposes to sell or otherwise transfer the Transfer Interests to a third party that is not an Affiliate of the holder at a price that is less than ninety percent (90%) of the Last Offer Price (the "Proposed Sale Price"), the holder shall, prior to consummating such sale or transfer of the Transfer Interests to the third party, make an offer to the Company in writing and in accordance with Section 19 (the "Second Sale Notice"), to sell the Transfer Interests to the Company at the Proposed Sale Price. (ii) Subject to Section 23.1(c) below, if the Company does not deliver to the holder written notice of acceptance of any offer made pursuant to Section 23.1(b)(i) within thirty (30) days after the Company's receipt of the Second Sale Notice, the Company shall be deemed to have waived its rights to purchase the Transfer Interests, and the holder shall be entitled to sell or otherwise transfer the Transfer Interests at the Proposed Sale Price to such unrelated third party within nine (9) months following the date of delivery of the Sale Notice, without the obligation to provide any further offers or notices to the Company. (c) If the holder proposes to sell or otherwise transfer the Transfer Interests to a third party that is not an Affiliate of the holder at any time after the expiry of the nine-month period referenced in Section 23.1(a)(ii) or Section 23.1(b)(ii), as the case may be, then the holder shall again be required to comply with all the obligations and requirements contained in Sections 23.1(a) and 23.1(b). (d) Payment of the Purchase Price shall be made in cash in immediately available funds within sixty (60) days after the date (if any) that a purchase price is agreed for the Company's purchase of the Transfer Interests. -25- 23.2 Minimum Amounts and Increments. Subject to Section 23.1, the Notes may be assigned in minimum amounts of $5,000,000 and in increments of $1,000,000 in excess thereof, provided that the holder may assign the Notes in a smaller minimum amount in connection with the transfer of all of the remaining Notes of such holder. 24.
