STOCK OPTION AGREEMENT

(US Employees)

Unless otherwise defined herein, the terms defined in the Danaher Corporation 2007 Stock Incentive Plan (the “Plan”) shall have the same defined meanings in this Stock Option Agreement (the “Option Agreement”).

Name:

Address:

The undersigned Optionee has been granted an Option to purchase Common Stock of the Company, subject to the terms and conditions of the Plan and this Option Agreement, as follows:

1. Grant of Option . The Company hereby grants to the Optionee named in the Notice of Stock Option Grant (the “Optionee”), an option (the “Option”) to purchase the number of shares (the “Shares”) set forth in the Notice of Stock Option Grant, at the exercise price per Share set

forth in the Notice of Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which are incorporated herein by reference. In the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail.

2. Vesting .

(a) Vesting Schedule . Except as may otherwise be set forth in this Option Agreement or in the Plan, Options awarded to an Optionee shall not vest until the Optionee (i) satisfies the performance-based vesting criteria (“Performance Objective”), if any, applicable to such Options and (ii) continues to be actively employed with the Company or an Eligible Subsidiary for the periods required to satisfy the time-based vesting criteria (“Time-Based Vesting Criteria”) applicable to such Options. The Performance Objective and Time-Based Vesting Criteria applicable to an Option are collectively referred to as “Vesting Conditions,” and the earliest date upon which all Vesting Conditions are satisfied is referred to as the “Vesting Date.” The Vesting Conditions for an Option received by an Optionee shall be established by the Compensation Committee (the “Committee”) (or by one or more members of Company management, if such power has been delegated in accordance with the Plan and applicable law) and reflected in the account maintained for the Optionee by an external third party administrator of the Option awards. Further, during any approved leave of absence, the Committee shall have discretion to provide that the vesting of the Options shall be frozen as of the first day of the leave and shall not resume until and unless the Optionee returns to active employment prior to the Expiration Date of the Options.

(b) Performance Objective . The Committee shall determine whether the Performance Objective applicable to an Option has been met, and such determination shall be final and conclusive. Until the Committee has made such a determination, the Performance Objective may not be considered to have been satisfied. Notwithstanding any determination by the Committee that the Performance Objective has been attained with respect to particular Options, such Options shall not be considered to have vested unless and until the Optionee has satisfied the Time-Based Vesting Criteria applicable to such Options.

(c) Age 65 . Notwithstanding the foregoing, the Time-Based Vesting Criteria applicable to all Options held by an Optionee shall be deemed 100% satisfied upon the Optionee’s attainment of age 65; provided that such Options shall remain subject to any applicable Performance Objective that remains unsatisfied as of such date.

3. Exercise of Option .

(a) Right to Exercise . This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Stock Option Grant and with the applicable provisions of the Plan and this Option Agreement.

(b) Method and Time of Exercise . This Option shall be exercisable by any method made available from time to time by the external third party administrator of the Option awards. An exercise may be made with respect to whole Shares only, and not for a fraction of a Share.

2

Shares shall not be issued under the Plan unless the issuance and delivery of such Shares comply with (or are exempt from) all applicable requirements of law, including (without limitation) the Securities Act, the rules and regulations promulgated thereunder, state securities laws and regulations, and the regulations of any stock exchange or other securities market on which the Company’s securities may then be traded. The Committee may require the Optionee to take any reasonable action in order to comply with any such rules or regulations. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date the Option is exercised with respect to such Shares.

(c) Acknowledgment of Potential Securities Law Restrictions . Unless a registration statement under the Securities Act covers the Shares issued upon exercise of an Option, the Committee may require that the Optionee agree in writing to acquire such Shares for investment and not for public resale or distribution, unless and until the Shares subject to the Award are registered under the Securities Act. The Committee may also require the Optionee to acknowledge that he or she shall not sell or transfer such Shares except in compliance with all applicable laws, and may apply such other restrictions as it deems appropriate. The Optionee also acknowledges that the U.S. federal securities laws prohibit trading in the stock of the Company by persons who are in possession of material, non-public information, and also acknowledges and understands the other restrictions set forth in the Company’s Insider Trading Policy.

4. Method of Payment . Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee:

(a) cash, delivered to the external third party administrator of the Option awards in any methodology permitted by such third party administrator;

(b) payment under a cashless exercise program approved by the Company or through a broker-dealer sale and remittance procedure pursuant to which the Optionee (i) shall provide written instructions to a licensed broker acceptable to the Company and acting as agent for the Optionee to effect the immediate sale of some or all of the purchased Shares and to remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for the purchased Shares and (ii) shall provide written direction to the Company to deliver the purchased Shares directly to such brokerage firm in order to complete the sale transaction; or

(c) surrender of other Shares which have been owned by the Optionee for more than six (6) months on the date of surrender, and have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the exercised Shares.

5. Termination of Employment .

(a) General . In the event the Optionee’s active employment with the Company or an Eligible Subsidiary terminates for any reason (other than death or Retirement), all unvested Options shall be automatically forfeited by the Optionee as of the date of termination. In the event the Optionee’s employment with the Company or an Eligible Subsidiary terminates for any reason (other than death, Disability, Retirement or Gross Misconduct), the Optionee shall have a period

3

of three (3) months, commencing with the date the Optionee is no longer actively employed, to exercise the vested portion of any outstanding Options.

(b) Death . Upon Optionee’s death, all unexpired options shall become fully exercisable and may be exercised for a period of twelve (12) months thereafter by the personal representative of the Optionee’s estate or any other person to whom the Option is transferred under a will or under the applicable laws of descent and distribution.

(c) Disability . In the event the Optionee’s employment with the Company or an Eligible Subsidiary terminates by reason of the Optionee’s Disability, all unvested Options shall be automatically forfeited by the Optionee as of the date of termination and the Optionee shall have until the first anniversary of the Optionee’s termination of employment for Disability to exercise the vested portion of any outstanding Options.

(d) Normal Retirement . In the event the Optionee voluntarily terminates his or her employment with the Company or an Eligible Subsidiary at or after reaching age 65, and as of the date of the Optionee’s Normal Retirement the Optionee holds Options that remain subject to any Performance Objective, the Options shall remain outstanding for up to the fifth anniversary of such date (or if earlier, up to the Expiration Date of the Option) to determine whether such conditions become satisfied (and if the Committee determines that the Performance Objectives are satisfied within such period, the Options shall remain outstanding and may be exercised up until the fifth anniversary of the date of the Optionee’s Normal Retirement (or if earlier, up until the Expiration Date of the Options)). In the event the Optionee voluntarily terminates his or her employment with the Company or an Eligible Subsidiary at or after reaching age 65, and as of the date of the Optionee’s Normal Retirement, the Optionee holds Options that are not subject to any unsatisfied Performance Objective, the Options shall remain outstanding and may be exercised up until the fifth anniversary of such date (or if earlier, up until the Expiration Date of the Option).

(e) Early Retirement . In the event the Optionee voluntarily terminates his or her employment with the Company or an Eligible Subsidiary prior to age 65 and the Committee determines that the cessation of Optionee’s employment constitutes Early Retirement, the Optionee’s unvested Options shall remain outstanding and shall continue to vest (as to both the Performance Objective and Time-Based Vesting Criteria, as applicable) for a period of five (5) years following the date of the Optionee’s Retirement.

(f) Gross Misconduct . If the Optionee’s employment with the Company or an Eligible Subsidiary is terminated for Gross Misconduct, the Optionee’s unexercised Options shall terminate immediately as of the time of termination, without consideration.

(g) Violation of Post-Employment Covenant . To the extent that any of the Optionee’s Options remain outstanding under the terms of the Plan or this Option Agreement after termination of the Optionee’s employment
