Exhibit 10.41

AMENDMENT DATED AS OF AUGUST 17, 2007 TO THE
AMERIPATH GROUP HOLDINGS, INC. 2006 STOCK OPTION AND RESTRICTED
STOCK PURCHASE PLAN (THE “PLAN”)

WHEREAS, on May 31, 2007, AmeriPath Group Holdings, Inc. (“AmeriPath”) became a
wholly-owned subsidiary of Quest Diagnostics Incorporated (“Quest Diagnostics”)
through a merger (the “Merger”) of a wholly-owned subsidiary of Quest
Diagnostics into AmeriPath.

WHEREAS, pursuant to the Agreement and Plan of Merger dated as of April 15, 2007
(the “Merger Agreement”) among Quest Diagnostics, Ace Acquisition Corporation
and AmeriPath, on May 31, 2007, each option to purchase shares of AmeriPath
granted under the Plan that was vested as of the closing (a “Vested Stock
Option”) was cashed out based on the intrinsic value of the vested options. The
cash payment was equal to (1) $6.67 (the difference between the transaction
value of $10.17 per share minus the exercise price of such Vested Option of
$3.50) multiplied by (2) the number of shares of AmeriPath covered by such
Vested Stock Option, less (3) any applicable withholding taxes.

WHEREAS, under the Merger Agreement, each option to purchase shares granted
under the Plan that was not vested as of the closing was converted into a
non-qualified option to purchase Quest Diagnostics Common Stock pursuant to a
formula intended to preserve the intrinsic value of such option. Under the
conversion formula, each unvested option to acquire one share of AmeriPath was
converted into a non-qualified option to acquire 0.2092 of a share of Quest
Diagnostics Common Stock, with the exercise price being adjusted by dividing the
previous AmeriPath exercise price ($3.50) by 0.2092, resulting in an exercise
price of $16.73.

WHEREAS, the Corporation desires to approve an amendment to the Plan to provide
that each option outstanding under the Plan as of June 1, 2007 shall vest on a
change of control (as defined below), which amendment was approved on August 17,
2007 by the Compensation Committee of the Board of Directors of Quest
Diagnostics.

NOW, THEREFORE, the Plan is amended by the addition of the following Section 6.3
effective as of June 1, 2007:

6.3 VESTING ON A CHANGE OF CONTROL. Each option outstanding on June 1, 2007 will
vest on a change of control provided that the option holder is employed by Quest
Diagnostics on the date of the change of control. In all other respects, each
option outstanding under the Plan on June 1, 2007 remains subject to the same
terms and conditions as were contained in the Plan as in effect on May 31, 2007
and the stock option agreement evidencing the option. The term “change of
control” shall mean and shall be deemed to occur if and when:
