Exhibit 99.4

[Quest Software Employee]:

As you are aware from previous communications, Quest Software recently completed a voluntary investigation of our stock option grant practices. As a result of that review, certain stock option grants awarded between 1998 and 2003 have been adjusted to reflect a revised grant date for financial accounting purposes. One or more of those options may also be deemed to have been granted at a discount and may be subject to adverse tax consequences under tax laws in certain countries (“Discounted Options”).

At the present time, Quest intends to launch a program that will offer you the opportunity to amend or replace Discounted Options in order to avoid these adverse tax consequences by increasing the exercise price of the Discounted Options to eliminate the discount; all other relevant features of the option will remain the same. Another feature of the remedial program, should you elect to participate, is that Quest Software would provide you with a cash bonus equal to the eliminated discount.

You have been identified as an employee who holds one or more Discounted Options. Your Discount Options are listed in the chart below.

Option Grant Number	Option Grant Date	# of Options Originally Granted	# of Options Outstanding	# of Options Exercisable	Exercise Price ($) USD
XXXXXXXXX	XX/XX/XXXX	XXXXX	XXXXX	XXXXX	XXXXX

Although employees may resume option exercises now, it may not be in your best interest to exercise these Discounted Options. If your circumstances require earlier exercise of your Discounted Options, we recommend that you first consult with your personal tax, legal and financial advisors so that you have an understanding of the tax implications that could result from such exercise.

The intended tender offer amendment/replacement program is important, and I urge you to read all program materials very carefully so you can make informed decisions. Please note that Quest Software is not recommending any particular course of action with respect to this offer and that we cannot offer specific tax or financial advice.

Please watch for further communications, including information sessions, the program announcement and materials that will be emailed to you in the coming weeks. If you have questions, please send them by email to tenderoffer@quest.com.

Thank you.
