The Seller shall continue to bear sole responsibility for the payment of all salaries and other benefits of any kind earned or accrued (whether or not vested or deemed vested at such time) by such employees prior to the Closing Date. The Seller shall terminate all such employees at the Closing Date, and the Purchaser shall engage as of the following Business Day such of those employees who accept the Purchaser’s offer of employment. The Purchaser shall be under no obligation to establish or continue, under the same or different terms or conditions, any employee benefit arrangement for any of the Seller’s employees, whether or not disclosed in Schedule 5.15(i) hereto, or as to which all benefits prior to the termination by Seller are not fully paid or provided for by Seller. The terms of such employment (other than the starting rate of cash compensation) shall be in the Purchaser’s sole discretion. The Seller shall not be responsible for providing any notice that may be required in accordance with 29 U.S.C. 2102.

Section 7.12 Non-Competition Agreement. For a period of three (3) years immediately following the Closing Date, Microsemi and its subsidiaries shall not, directly or indirectly, anywhere in the world, engage in the design, development, assembly, marketing, distribution or sale of the Products or derivative products within the same product family or products addressing the same sockets or applications

in which the Products are currently used. Without limiting the generality of Section 11.4, the provisions of this Section 7.12 shall inure to the benefit of any successors and assigns of the Purchaser of the business as acquired hereunder and as the same develops in the normal course of business, provided that this non-competition agreement is assigned to such transferee by written agreement, which shall have been first submitted by APT to Microsemi and approved by Microsemi, which approval shall not be withheld unreasonably, and such transferee continues to conduct the business acquired hereunder. In the event that the Seller or Microsemi merges, consolidates or otherwise combines with, transfers, sells or disposes of substantially all of its assets to, another person, whether in one transaction or a series of related transactions, the Seller and Microsemi shall use reasonable efforts to procure from any successor, purchaser or other transferee, as the case may be, a written agreement to comply with the provisions of this Section 7.12, as if such successor, purchaser or other transferee were a party hereto. Notwithstanding any term or provision herein or elsewhere, this Section 7.12 shall not apply to or restrict any successor or transferee of Microsemi in the conduct of any business conducted by such successor or transferee prior to becoming a successor or transferee of Microsemi or acquired from any unrelated party by such successor or transferee at any time after such entity became a successor or transferee of the Seller or Microsemi.

(c) Any Person providing indemnification pursuant to the provisions of this Section 10.2 is hereinafter referred to as an “Indemnifying Party” and any Person entitled to be indemnified pursuant to the provisions of this Section 10.2 is hereinafter referred to as an “Indemnified Party.”

(d) Any claim made under this Agreement shall be made only pursuant and subject to this Article 10:

(i) Except for payment of the Purchase Price under Section 4.1 and the assumption of the Assumed Liabilities, no claim shall be made except to the extent that the aggregate of all claims suffered by a Party exceeds $300,000;

(ii) No claim shall be made based on a particular representation or warranty after the expiration thereof in accordance with this Article 10;

In the case of any claim for indemnification arising from a claim of a third party, an Indemnified Party shall give prompt written notice, in no event more than 10 days following such Indemnified Party’s receipt of such claim or demand, to the Indemnifying Party of any claim or demand which such Indemnified Party has knowledge and as to which it may request indemnification hereunder; provided, however, that the Indemnifying Party shall not be relieved of its indemnification obligations pursuant to this sentence except only to the extent that the Indemnified Party’s delay in giving such notice impairs the ability of the Indemnifying Party to defend against the claim or demand. Notwithstanding the immediately preceding sentence, all notices asserting a claim for indemnification based on a representation or warranty, to be effective, must be given in writing to the Indemnifying Party before the expiration of such representation or warranty pursuant to Section10.1 and in accordance with Section 10.2(d)(ii).

Notwithstanding anything in this Agreement to the contrary, the Indemnified Party shall, at the expense of the Indemnifying Party, cooperate with the Indemnifying Party, and keep the Indemnifying Party fully informed, in the defense of such claim or demand. The Indemnified Party shall have the right to participate in the defense of any claim or demand with legal counsel employed at its own expense; provided, however, that, in the case of any claim or demand described in clause (i) or (ii) of the second preceding sentence or as to which the Indemnifying Party shall not in fact have employed legal counsel to assume the defense of such claim or demand, the reasonable fees and disbursements of such counsel shall be at the expense of the Indemnifying Party. The Indemnifying Party shall have no indemnification obligations with respect to any such claim or demand which shall be settled by the Indemnified Party without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
