AMENDMENT TO EMPLOYMENT AGREEMENT

Exhibit 10.35

AMENDMENT TO

EMPLOYMENT AGREEMENT

This AMENDMENT TO EMPLOYMENT AGREEMENT, dated November 17, 2008, is by and between ZOLL MEDICAL CORPORATION, a Massachusetts corporation (the “Company”), and Richard A. Packer (the “Executive”).

WHEREAS, the Company and the Executive entered into an employment agreement effective as of July 19, 1996 (the “Agreement”); and

WHEREAS, the parties desire to amend the Agreement to comply with and meet the requirements of the provisions of Section 409A of the Internal Revenue Code of 1986, as amended.

NOW, THEREFORE, the Company and the Executive, each intending to be legally bound hereby, do mutually covenant and agree as follows:

1. Section 5 of the Agreement is hereby amended by adding the following sentence to the end of such section:

“With respect to the Company’s payment of 12 months salary to the Executive, such salary shall be paid in installments in accordance with the Company’s then current payroll practices, commencing on the first pay date which is on or immediately after the 30-day notice period. Solely for purposes of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), each installment payment is considered a separate payment.”

2. The Agreement is hereby amended by adding a new Section 8 immediately after Section 7 thereof as follows:

“8. Section 409A. Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s separation from service within the meaning of Section 409A of the Code, the Company determines that the Executive is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the Executive becomes entitled to under this Agreement on account of the Executive’s separation from service would be considered deferred compensation subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the Executive’s separation from service, or (B) the Executive’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule.

The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).

The Company makes no representation or warranty and shall have no liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.”

3. The Agreement otherwise remains in full force and effect as to all other provisions under said Agreement.

IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the date first above written.
