EXPLANATORY NOTE

This Amendment No. 1 on Form 10-K/A (this Amendment) amends our Annual Report on Form 10-K for the fiscal year ended
December 31, 2011 that was filed with the Securities and Exchange Commission (SEC) on February 29, 2012 (the Original Filing). We are filing this Amendment to include the information required by Part III and not
included in the Original Filing, as we will not file our definitive proxy statement within 120 days of the end of our fiscal year ended December 31, 2011.

Pursuant to Rule 12b-15 under the Securities and Exchange Act of 1934, as amended (the Exchange Act), this Form 10-K/A also contains new certifications pursuant to Section 302 of the
Sarbanes-Oxley Act of 2002. Accordingly, subsection (a)(3) of Item 15, Exhibits, of Part IV has also been amended and restated in its entirety to include the currently dated certifications as exhibits. Because no financial statements
have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted.

Except as set forth in Part III and subsection (a)(3) of Item 15 of Part IV below, no other changes or amendments are made to the
Original Filing other than the deletion of the reference on the cover of the Original Filing to the incorporation by reference of Quest Software, Inc.s (Quest, Quest Software, the Company, we,
us or our) definitive proxy statement into Part III of the Original Filing. Unless expressly stated, this Amendment does not reflect events occurring after the filing of the Original Filing, nor does it modify or update in
any way the disclosures contained in the Original Filing.

awarded or paid to, or earned by, each of our named executive officers during the last completed fiscal year, and how such compensation components advance and serve our overall
compensation objectives and strategies. Our named executive officers in fiscal year 2011 and their titles during that year were: Douglas F. Garn, President and Chief Executive Officer; Scott J. Davidson, Senior Vice President and Chief Financial
Officer; Vincent C. Smith, Executive Chairman; Steve Dickson, Senior Vice President of Product Management; and Alan Fudge, Senior Vice President of Worldwide Sales and Marketing. In January 2012, Mr. Dicksons title was changed to Senior
Vice President and General Manager, Windows Server Management Business Segment. On February 14, 2012, Mr. Garn resigned from his position as President and Chief Executive Officer for health reasons and was appointed to the newly-created
executive position of Vice Chairman of the Company. Mr. Garn remains a director of the Company. Also on February 14, 2012, Mr. Smith was appointed to replace Mr. Garn as President and Chief Executive Officer, and he was
redesignated as Chairman of the Board.

Executive Compensation Objectives and Philosophy

The overall objectives of our compensation programs for our named executive officers are to:



| |  |  | provide overall compensation that is sufficient to attract, motivate and retain executives of outstanding ability and potential;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | link executive compensation to the achievement of objectively and subjectively measurable corporate and individual goals and objectives;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide incentives to operate the company in a manner consistent with the Companys short-term and long-term strategic performance goals and
objectives; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | align the interests of our executives with those of our stockholders, with the ultimate objective of improving stockholder value.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------

We are engaged in the highly competitive software industry. The Compensation Committee of the Board of
Directors (the Committee) recognizes that our continued success depends upon the ability to attract and retain qualified executives through competitive compensation programs for our named executive officers.

Role of Compensation Committee and Outside Consultants

Our Board of Directors has delegated to the Committee the power and authority to review, modify and approve our compensation strategy and policies. The Committees charter is available on the
Corporate Governance page of our Investor Relations website located at http://www.quest.com/investor_relations/. The Committee is currently comprised of three independent directors: Paul A. Sallaberry (Chairman), H. John Dirks, and Augustine L.
Nieto II. The Board of Directors has delegated to the Committee the responsibility for:



| |  |  | reviewing, modifying and approving the compensation of our named executive officers;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | establishing our executive compensation programs and periodically reviewing and modifying the operation of those programs;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | reviewing and approving corporate performance goals and objectives relevant to the compensation of our named executive officers, based upon our
business needs and consistent with the interests of our stockholders;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | administering our equity compensation plans and our executive compensation plans, programs and policies;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | monitoring corporate performance and its relationship to the compensation of named executive officers; and
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | making appropriate recommendations to the Board of Directors concerning matters of executive compensation.
| | - |  | ----------------------------------------------------------------------------------------------------------

The Committee meets regularly to discuss executive compensation matters. At least annually, usually near the beginning of the year, the
Committee performs a review of the total compensation packages of our named executive officers. In determining a named executive officers total compensation package, the Committee considers and reviews each of the components of compensation
that we offer our named executive officers to ensure consistency with our compensation philosophy and objectives. The Committee then determines whether the existing compensation programs are meeting our

##### Table of Contents

overall compensation objectives and philosophy and may implement adjustments to achieve a package of total compensation for each of our named executive officers. The Committee considers whether
and to what extent developments in compensation trends should affect our compensation policies and objectives.

At our annual
meeting of stockholders in June 2011, we provided stockholders an advisory vote to approve the compensation of our named executive officers (the say-on-pay proposal). At the June 2011 annual meeting, our stockholders approved the
compensation of our named executive officers, with approximately 85% of the votes cast in favor of the say-on-pay proposal. In evaluating our executive compensation program, the Committee considered the results of the say-on-pay proposal and
numerous other factors as discussed herein. While each of these factors informed the Committees decisions regarding the compensation of our named executive officers, the Committee has not implemented significant changes to our 2011 executive
compensation program. The Committee will continue to monitor and assess our executive compensation program and consider the outcome of our say-on-pay votes when making future compensation decisions for our named executive officers.

The Committee considers input from our senior management (in 2011, our Executive Chairman, our Chief Executive Officer, our Vice
President, General Counsel and Secretary, and our Vice President, Human Resources) in determining both the total amount of compensation for our named executive officers and the allocation between different types of compensation. Our senior
management also discusses with the Committee our corporate performance goals during the applicable performance period and makes recommendations regarding the relative weights to assign to the different performance objectives when the Committee uses
multiple objectives. Neither our Executive Chairman nor our Chief Executive Officer is present during the Committees voting or final deliberations regarding the compensation of our named executive officers.

The Committee has the authority to engage its own outside compensation consultants, at the Companys expense, and to commission
compensation studies or surveys to obtain data and advice regarding the amount and types of compensation we provide to our named executive officers and how these compare to compensation practices generally in our industry. For 2011, the Committee
engaged Pay Governance LLC to assist with the Committees review of the compensation of our named executive officers against a group of comparable software companies and to provide advice concerning compensation for our named executive
officers. The Committee also utilized external market data from Equilar, a leading executive compensation company, to compare the compensation programs for our named executive officers with the compensation packages provided to executives with
similar responsibilities at software companies that are similar in size to Quest. The Committee determined not to engage in formal compensation benchmarking for 2011, but rather directed our Vice President of Human Resources to prepare a
market check comparison of the overall compensation levels of our named executive officers against a group of similarly sized software companies using the data provided by Equilar and review by executive compensation consultants at Pay
Governance LLC.

The Committee approved the 2011 compensation arrangements for our named executive officers in March 2011.

Elements of Total Compensation

To achieve the objectives of our compensation programs, we use the following principal forms of compensation for our named executive officers, each of which is discussed in detail below:



| |  |  | base salary;
| | - |  | ------------



| |  |  | performance-based, variable compensation in the form of cash incentive bonuses and, in certain previous years but not in 2011, equity-based incentive
awards;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | discretionary cash bonuses;
| | - |  | ---------------------------



| |  |  | non-variable equity compensation in the form of stock options;
| | - |  | --------------------------------------------------------------



| |  |  | retirement savings and other customary employee benefits;
| | - |  | ---------------------------------------------------------



| |  |  | limited use of perquisites; and
| | - |  | -------------------------------



| |  |  | limited use of change of control benefits.

##### Table of Contents

The Committees compensation decisions for 2011 were shaped by a philosophy of
providing incentives for executives to increase the Companys growth and to create consistent, long-term performance. The Committee seeks to align the interests of our named executive officers with the interests of our stockholders through
compensation tied to the achievement of both short-term and long-term performance goals. The Committee has designed the executive compensation arrangements to include performance-based features that provide economic incentives to outperform stated
goals.

The Committee generally believes that on-target total compensation for each of our named executive
officers should be at approximately the 60thto 75thpercentile of comparable software companies, based on the individual
named executive officers tenure in his position at Quest and experience in similar positions at other companies, if pre-determined performance objectives are reached at the target level.

Beginning in 2009, the Committee was faced with the challenge of designing a compensation package for Mr. Smith, who in 2011
occupied a unique position as Executive Chairman that lacked ready comparison to positions within other companies. Having served as a director since 1995 and as our Chief Executive Officer from 1997 to 2008, Mr. Smith brought invaluable
knowledge and experience to his active and continuing role within the Companys leadership during 2011. The Committee believes that Mr. Smiths compensation package for 2011 provided appropriate incentives for him to remain engaged in
the Companys business.

Base Salary

We pay our named executive officers a base salary to compensate them for the services they provide throughout the year. Although base salary has traditionally comprised a substantial portion of the
overall compensation of our named executive officers, the Committee does not target salary as a specific percentage of total compensation. To attract and retain qualified personnel, and because of the competitive industry in which we operate, we
feel it is necessary to pay each of our named executive officers a base salary that is competitive with other software and technology companies with which we compete for personnel. In considering and determining the appropriate base salary for our
named executive officers, the Committee reviews market data to compare the salaries we offer to our named executive officers to salaries paid to executives holding similar positions at companies with similar characteristics  generally,
software companies with similar revenues or a similar market capitalization. Based on its review of the Companys prior year performance and overall market conditions, including a market check of compensation levels at comparable companies, the
Committee determined to maintain Mr. Garns, Mr. Smiths, and Mr. Davidsons 2011 base salaries at their 2010 levels (Mr. Garn - $850,000; Mr. Smith - $1,000,000; Mr. Davidson - $425,000) and to increase the
other named executive officers 2011 base salaries over 2010 levels as follows: Mr. Dickson - $425,000 (increased from $400,000 in 2010) and Mr. Fudge - $500,000 (increased from $425,000 in 2010).

Performance-Based Variable Compensation

Overview.The Company has adopted an Executive Incentive Plan (EIP) for purposes of compensating our named executive officers. The EIP is a variable incentive program designed to
motivate participants to perform to the best of their abilities and achieve Quests financial and other performance objectives. Awards under the EIP may be paid in cash, common stock, stock units, restricted stock, or restricted stock units, at
the Committees discretion. From the EIPs inception, we have made all awards under the EIP in cash and, in some years, also in equity-based awards in the form of restricted stock units. For 2011, all awards under the EIP were made in
cash.

Payments under the EIP are only earned if, and to the extent, performance objectives predetermined by the Committee are
achieved. Near the beginning of each fiscal year, management prepares an operating plan and forecast detailing the anticipated level of revenues and other business activities for that fiscal year. The plan does not take into account the impact of
any acquisitions during the year. This operating plan is presented to the Board of Directors and the Committee uses this plan to establish target performance objectives for the determination of any cash bonuses and equity-based awards to be paid to
our named executive officers under the EIP. The EIP permits the Committee to select one or more performance objectives each year from among various criteria, including: total revenues, license revenues, service revenues, new orders or bookings,
sales growth, operating income, operating margin, earnings per share, earnings before interest, taxes, depreciation and amortization and stock-based compensation, cash flow, net income, operating cash flow, return on assets, return on total
stockholder equity, return on sales, assets, capital or investments, total stockholder return, cost reduction goals, increase in our trading price, or measures of customer satisfaction, or any combination of, or a specified increase in, any of the
foregoing.

The Committee administers the EIP and determines the basis on which to measure the performance objectives that
have been selected for a given year. Certain performance objectives may be measured in accordance with generally accepted accounting principles applied by the Company on a consistent basis, and others may be measured on a pro forma
basis,

excluding from the calculation of such objectives non-cash, non-recurring, extraordinary and certain other items, provided that such adjustments are in conformity with those reported by the
Company on a non-GAAP basis. In addition, such performance objectives may be based upon the performance of any of the Companys business groups or division thereof or any subsidiary. Performance objectives may differ from participant to
participant, from performance period to performance period and from award to award. The EIP is intended to permit the payment of bonuses that qualify as performance-based compensation under section 162(m) of the Internal Revenue Code of 1986, as
amended (the Code), and members of the Committee must qualify as outside directors under Section 162(m). Subject to the terms of the EIP, the Committee has all discretion and authority necessary or appropriate to control
and manage the operation and administration of the EIP. The Committee or the Board generally may amend or terminate the EIP at any time and for any reason.

The performance period applicable to our 2011 cash bonus awards under the EIP was the twelve-month period from January 1, 2011 through December 31, 2011. For 2011, the Committee chose to
establish performance objectives based on achievement levels of two criteria, total revenues and pro forma operating margin, for the full year, excluding the results of operations of companies acquired in 2011. Pro forma operating margin is a
non-GAAP measure comprised of a percentage of total revenues, excluding amortization of intangible items, stock-based compensation expenses, acquisition-related costs, and expenses. The performance objectives are assessed independently of each
other. Thus, the named executive officers may receive payment based on the Companys achievement level of one performance objective, even if the Company fails to perform at a level required to receive payment under the other performance
objective. For 2011, the performance objectives were weighted 60% to total revenues and 40% to pro forma operating margin.

Performance-Based Variable Compensation  Cash Bonus Awards. In March 2011, the Committee established target incentive cash
bonus awards for the named executive officers under the EIP for 2011 as follows: Mr. Garn - $595,000 (allocated $357,000 to the total revenues objective and $238,000 to the pro forma operating margin objective); Mr. Davidson - $182,000
(allocated $109,200 to the total revenues objective and $72,800 to the pro forma operating margin objective); Mr. Smith - $700,000 (allocated $420,000 to the total revenues objective and $280,000 to the pro forma operating margin objective);
Mr. Dickson - $140,000 (allocated $84,000 to the total revenues objective and $56,000 to the pro forma operating margin objective); and Mr. Fudge - $250,000 (allocated $150,000 to the total revenues objective and $100,000 to the pro forma
operating margin objective). These performance-based variable cash bonus amounts comprised 70% for Messrs. Garn, Davidson, Dickson, and Smith, and 71.43% for Mr. Fudge, of the total cash bonus amounts for which the named executive officers were
eligible in 2011, with the remaining amounts allocated to the discretionary bonuses described below under the caption Discretionary Cash Bonuses.

The Committee determined that the maximum cash bonus award any named executive officer could earn under the EIP for 2011 was 125% of such named executive officers target cash bonus award. Under the
terms of the EIP, the amount of the ultimate award may be reduced if actual achievement of the performance criteria is determined to be below the specified objectives. The Committee retains further discretion to reduce or eliminate (but not
increase) the cash bonus awards that would otherwise be payable under the EIP.

The tables below depict in detail the
threshold performance objective percentages required to obtain the associated percentages of the target cash bonus awards under the EIP as established by the Committee for 2011. As the performance objective percentages increase within the tiers
shown in the tables, the associated percentages of the target cash bonuses to be paid increase on a straight-line basis.

For 2011, an award of 100% of the named executive officers target cash bonus for the total revenues
objective would have been awarded if the Company achieved total revenues of $889,739,000. An award of 100% of the named executive officers target cash bonus for the pro forma operating margin objective would have been awarded if the Company
achieved a pro forma operating margin of 21.2% during the performance period. Under the total revenues objective, no cash bonus would have been paid had the Company performed below 90% of the target level. Under the pro forma operating margin
objective, no cash bonus would have been paid had the Company performed below the 20.2% level.

For 2011, the Company achieved
$842,224,498 in total revenues, as determined in accordance with the EIPs criteria and excluding the results of operations of companies acquired in 2011 (i.e., 94.66% of the total revenues objective), resulting in payment of 48.50% of the
target cash bonus award amounts under this objective. For 2011, the Company achieved a pro forma operating margin of 19.94%, as determined in accordance with the EIPs criteria, and excluding the results of operations of companies acquired in
2011, resulting in payment of 0% of the target cash bonus award amounts under this objective. Based on these achievement levels and the weights assigned to the performance criteria (60% to total revenues and 40% to pro forma operating margin), in
February 2012 the Committee awarded cash bonuses under the EIP to our named executive officers for 2011 performance in the following amounts: Mr. Garn - $173,145 (allocated $173,145 to the total revenues objective and $0 to the pro forma
operating margin objective); Mr. Davidson - $52,962 (allocated $52,962 to the total revenues objective and $0 to the pro forma operating margin objective); Mr. Smith - $203,700 (allocated $203,700 to the total revenues objective and $0 to
the pro forma operating margin objective); Mr. Dickson - $40,740 (allocated $40,740 to the total revenues objective and $0 to the pro forma operating margin objective); and Mr. Fudge - $72,750 (allocated $72,750 to the total revenues
objective and $0 to the pro forma operating margin objective).

Performance-Based Variable Compensation  Equity-Based
Awards. In certain previous years, we have awarded performance-based equity awards to the named executive officers under the EIP in the form of restricted stock units, in addition to the cash awards discussed above. The awards of
performance-based restricted stock units for achievement of performance objectives was designed to promote a longer-term interest in our performance and success in ways that we intended to result in increased value for our stockholders. The named
executive officers had to achieve the specific performance objectives and remain employed with Quest through the vesting period in order to realize any value from the restricted stock units. These performance-based equity awards to our named
executive officers were issued in accordance with our 2008 Stock Incentive Plan and were intended to qualify as performance-based compensation under section 162(m) of the Code. However, beginning in 2010 and continuing in 2011, the Committee
determined not to include performance-based equity awards in our named executive officers compensation packages. Also, beginning in 2010 and continuing in 2011, the Committee eliminated restricted stock units from our named executive
officers compensation altogether in favor of stock options as an incentive for driving growth and as a tool for rewarding performance that increases stockholder value, as stock options have value only if our stock price increases, whereas
restricted stock units retain value even if our stock price remains flat or declines.

Discretionary Cash Bonuses

Outside of our EIP, we offer other discretionary incentive cash bonus opportunities to our named executive officers that
are designed to provide incentives for the named executive officers to perform to the best of their abilities and achieve certain individual operational, strategic and regional objectives and initiatives or complete certain projects. The named
executive officers will become entitled to earn some or all of their respective target discretionary cash bonus amounts, including the opportunity to earn up to 125% of their target cash bonus amounts, based on the Committees subjective
evaluation of the individuals performance in the context of general economic and industry conditions and the Companys performance. The discretionary cash bonuses are determined wholly at the discretion of the Committee and generally are
not linked to pre-established objective performance measures. The Committee believes that this discretionary cash bonus arrangement is an appropriate mechanism for rewarding and motivating the named executive officers because each named executive
officer is responsible for, among other things, strategic objectives that cannot always be stated in quantitative or objective terms or measured by traditional financial metrics during the performance period. This more subjective arrangement
provides the Committee with a powerful and flexible tool to shape the named executive officers behavior. The Committee believes that achievement of the results rewarded by the discretionary cash bonuses will lead to increased stockholder
value, thereby providing an incentive to our named executive officers in the performance of their duties that is aligned with the interests of our stockholders.

##### Table of Contents

In setting target discretionary cash bonus amounts, the Committee considers its expectations
for the business functions headed by each named executive officer and the named executive officers potential for achieving these expectations. For each named executive officer, the Committee establishes broadly-worded strategic management
objectives stated in qualitative, non-quantifiable terms designed to shape the named executive officers performance and activities. In March 2011 the Committee established the following target discretionary cash bonus amounts for the named
executive officers: Mr. Garn - $255,000; Mr. Davidson - $78,000; Mr. Smith - $300,000; Mr. Dickson - $60,000; and Mr. Fudge - $100,000. These discretionary cash bonus amounts comprised 30% for Messrs. Garn, Davidson,
Dickson, and Mr. Smith, and 28.57% for Mr. Fudge, of the total cash bonus amounts for which the named executive officers were eligible in 2011, with the remaining amounts allocated to the discretionary bonuses described above under the
caption Performance-Based Variable Compensation  Cash Bonus Awards.

In evaluating the named executive
officers performance and determining the discretionary cash bonus amounts, the Committee makes a subjective assessment of the named executive officers performance in light of the qualitative management objectives and considers the target
discretionary bonus amounts that were previously established. After the end of 2011, the Committee met to discuss the appropriate amount to be paid pursuant to the discretionary bonuses for Messrs. Garn, Davidson, Smith, Dickson and Fudge for 2011
performance. After evaluating each of the named executive officers performance against the previously established qualitative management objectives for 2011, and taking into consideration the Companys performance against its operating
plan for 2011, the Committee determined to pay each of Messrs. Garn, Davidson, Smith, and Fudge 85%, and Mr. Dickson 75%, of their target discretionary cash bonus amounts, as follows: Mr. Garn - $216,750; Mr. Davidson - $66,300;
Mr. Smith - $255,000; Mr. Dickson - $45,000; and Mr. Fudge - $85,000.

Non-Variable Equity Compensation
 Stock Options

In addition to the performance-based variable equity compensation program described above, we provide
our named executive officers with non-variable equity-based incentives pursuant to our 2008 Stock Incentive Plan to motivate them to achieve our long-term goals. These equity-based incentives also serve to align the interests of our named executive
officers with the interests of our stockholders. Our 2008 Stock Incentive Plan was established as the successor to our 1999 Stock Incentive Plan and 2001 Stock Incentive Plan to provide all of our employees, including our named executive officers,
with an opportunity to share, along with our stockholders, in our long-term performance. The Committee believes that a primary goal of our equity compensation program should be to provide key employees who have significant responsibility for our
management, growth and future success with an opportunity to obtain an ownership interest, or to otherwise increase their ownership interest, in Quest, as an incentive for them to remain as an employee of Quest. We also feel that awarding equity
compensation will also provide incentives for our named executive officers to work hard and strive to achieve our long-term strategic performance goals and objectives by giving each a stake in the outcome.

Named executive officers are eligible to receive non-variable equity compensation in the form of stock options at the discretion of the
Committee. Option awards give the named executive officers the right to purchase shares of our common stock in the future at a price equal to the fair market value at the date of grant. Historically, the amount of stock options granted to our named
executive officers has varied widely and was determined at the discretion of the Committee, with input from our Chief Executive Officer. All such grants are subject to the terms and conditions of our 2008 Stock Incentive Plan. We believe that the
grant of stock options having an exercise price equal to the fair market value on the date of grant provides our named executive officers with an incentive to build stockholder value, since the named executive officers will only realize value in the
stock options if there is stock price appreciation. Outstanding options held by named executive officers typically vest over a period of five or six years and expire ten years from the date of grant. We believe the vesting period provides us with an
executive retention tool, as well as providing an incentive to our named executive officers to increase long-term stockholder value. In March 2011, we awarded our named executive officers stock options covering the number of shares of our common
stock as follows: Mr. Garn - 400,650; Mr. Davidson - 155,500; Mr. Smith - 575,000; Mr. Dickson - 110,000; and Mr. Fudge - 140,000. In September 2011, to align the interests of our named executive officers with those of our
stockholders and to provide additional retention incentives, we awarded our named executive officers additional stock options covering the number of shares of our common stock as follows: Mr. Garn - 260,000; Mr. Davidson - 100,000;
Mr. Smith - 375,000; Mr. Dickson - 100,000; and Mr. Fudge - 91,000.

Retirement and Other Benefits

We make available to each of our employees, including our named executive officers, a variety of employee benefit
programs, including a 401(k) plan, medical, vision and dental benefits plans, short-term and long-term disability insurance, life insurance and certain other standard employee health and welfare benefit plans. Our named executive officers are
eligible

to participate in such plans to the same extent and on the same terms as all of our other employees. Our Board of Directors typically makes a discretionary matching contribution under our 401(k)
plan to all participants once annually in February, based on our financial performance during the previous year. For 2011, we provided a discretionary matching contribution in the amount of up to $3,000, which is an increase to the $2,750 amount of
the matching contribution in 2010. We believe that we must offer a comprehensive and competitive employee benefits program to attract and retain our key executives.

Perquisites

In addition to the compensation programs described above and
the benefits programs that are generally available to all of our salaried employees, in years prior to 2008 we also provided our named executive officers with certain limited perquisites. These additional benefits principally consisted of company
automobiles or automobile allowances for certain named executive officers, and costs of attending our annual sales quota club trip (including related tax gross-up benefits). While we believe these limited perquisites and other personal benefits were
reasonable in nature and amount and consistent with the overall objectives of our compensation programs to enable us to attract, motivate and retain outstanding executives in our most critical positions, we did not provide our named executive
officers with any perquisites or other personal benefits in 2009, 2010 or 2011 other than: costs and related tax gross-up benefits for our annual sales quota club trip; certain meal, travel and entertainment expenses incurred by our named executive
officers and their spouses at company-sponsored sales and marketing events; certain moving expense reimbursements and related tax gross-up benefits for Mr. Fudge in connection with his move to Southern California upon joining Quest in August
2009; and a portion of the race entry fee incurred by Mr. Fudge for an automobile bearing our Companys logo. These limited perquisites are set forth in the footnotes to the Summary Compensation Table below.

Equity Compensation Practices

Market Timing of Equity Awards

The Committee does not engage in any
market timing of equity awards made to our named executive officers or other award recipients. There is no established practice of timing the grant of our equity awards in advance of the release of favorable financial results or
adjusting the award date in connection with the release of unfavorable financial developments affecting our business. Under our current practice, equity awards for all officers are made by the Committee. All stock option grants will have an exercise
price per share equal to the fair market value of our common stock on the date of grant, as determined in accordance with the plan under which such options are granted.

Equity Award Grant Policy

The Committee has adopted a Policy and
Procedures for the Granting of Stock Options and Other Equity-Based Incentives (the Granting Policy and Procedures) to provide a consistent procedure for the Committee to follow in the granting of equity awards, including procedures for
the documentation, implementation and communication of equity awards. A copy of the Granting Policy and Procedures is available on the Corporate Governance page of our Investor Relations website located at http://www.quest.com/investor_relations/.
The Granting Policy and Procedures provides, among other things, that:



| |  |  | in advance of each Committee meeting, management shall provide to the Committee a list of all officers, employees and Board members for whom management
(or, in the case of Board members, the Board) recommends an equity award;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the grant date of all options (other than annual option grants) shall be the date of approval by the Committee or such other date after such date of
approval as may be specified by the Committee, provided such date falls within an open trading window (if such date does not fall within an open trading window, the grant date shall be the first day of an open trading window after such date);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the exercise price for all options shall be the Fair Market Value on the date of grant (as defined in the equity plan from which the option
award is made); and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the grant date for all annual awards shall be the date of Quests annual meeting of stockholders or such other date following such annual meeting
as may be specified by the Committee.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Change in Control and Severance Payments

We have entered into arrangements with certain of our executive officers that provide for certain limited benefits upon a change of
control. For a discussion of these arrangements, please see Potential Payments upon Termination or Change in Control below.

Deductibility of Executive Compensation

As part of its function, the Committee reviews and considers the deductibility of executive compensation under Section 162(m) of the
Code which limits the annual deduction we can claim for federal income tax purposes of no more than $1 million of compensation paid to certain named executive officers (as determined in accordance with Section 162(m)) in a taxable year.
Compensation above $1 million may be deducted if it is performance-based compensation within the meaning of the Code. In certain situations, the Committee may approve compensation arrangements that do not meet these requirements to
ensure competitive levels of total compensation for our named executive officers.

Policy With Respect to Stock Ownership Requirements

We do not have a policy establishing security ownership requirements for our named executive officers. Our named
executive officers have considerable ownership in Quest stock, which the Committee believes sufficiently aligns their interests with the interests of our stockholders.

target-level amount of these performance-based options established by the Committee in February 2009 was 186,500. Due to the Companys achievement above the threshold but below the target level of the applicable performance measures, in
February 2010 the Committee determined that the actual number of options awarded was 165,787. The options vest and become exercisable for the total number of option shares over a period of 3 years, with 1/3 vesting on March 1, 2010, 1/3 vesting

Potential Payments upon Termination or Change in Control

Certain equity award arrangements with our named executive officers provide certain limited benefits in the event of a change in control
of Quest. Specifically, our 1999 Stock Incentive Plan and 2001 Stock Incentive Plan provide that in the event of a change in ownership or control of Quest (by way of merger, sale of assets or otherwise), each outstanding option under the
discretionary option grant program will immediately become exercisable for all the shares represented by such option, except to the extent (i) such option is assumed or otherwise continued in full force and effect by the successor corporation;
or (ii) such option is replaced with a cash incentive program by the successor corporation which preserves the economic value existing at the time of any such change in ownership or control and provides for subsequent payout in accordance with
the same vesting schedule applicable to those option shares. Our 2008 Stock Incentive Plan, which is a successor to our 1999 Stock Incentive Plan and 2001 Stock Incentive Plan, provides that in the event of a change in control, our Board of
Directors may arrange for a variety of actions with respect to stock-based awards, such as assumption by the acquiring corporation, acceleration of vesting, or cash payment. In addition, our 2008 Stock Incentive Plan provides that stock-based award
agreements may include provisions subjecting such awards to accelerated vesting immediately upon or, in the event of a termination, within a designated period after a change in control transaction. These acceleration provisions do not discriminate
in scope, terms or operation in favor of our named executive officers and are available generally to all of our employees who have been granted stock options and restricted stock units. Assuming a change of control resulting in the acceleration of
vesting of all outstanding unvested equity awards to our named executive officers on December 31, 2011, our named executive officers would be entitled to receive the following payments for such accelerated unvested equity awards based on the
closing price of our common stock on that day, $18.60: Mr. Garn - $1,907,696 for accelerated stock options and $551,137 for accelerated RSUs; Mr. Davidson - $675,129 for accelerated stock options and $172,087 for accelerated RSUs;
Mr. Smith - $4,099,049 for accelerated stock options; Mr. Dickson - $475,475 for accelerated stock options and $22,041 for accelerated RSUs; and Mr. Fudge - $545,594 for accelerated stock options.

On March 8, 2012, we entered into an agreement (the Merger Agreement) to become a private company (the
Merger). In connection with this transaction, on March 8, 2012, the Board of Directors entered into a Change in Control Severance Plan (the Plan) in order to encourage certain management-level employees of the Company to
continue to focus on the best interests of the Companys stockholders and provide severance protections to such employees in the event their employment is terminated in connection with a change of control of the Company. Of our named executive
officers, Messrs. Davidson, Dickson, and Fudge are participants in the Plan. For purposes of the Plan, the term change in control is defined as consummation of any transaction that the Board shall have determined is a Superior Proposal
(as defined in the Merger Agreement). The consummation of the Merger will not be considered a change in control for purposes of the Plan. Under the terms of the Plan and subject to the conditions thereof, a participant in the Plan will receive
severance benefits and accrued rights if his or her employment is terminated involuntarily by the Company or any of its affiliates other than for cause (as defined in the Plan), or by resignation of the employee for good reason (as defined in the
Plan), on or before the two-year anniversary of a change in control. An employee who leaves his or her employment for any reason other than good reason, as defined in the Plan, shall not receive severance benefits. A Plan participant shall receive a
cash severance benefit, payable in a lump sum, equal to the product of (i) 1/12 of the participants annual rate of base salary in effect immediately prior to such participants termination date and (ii) the number of months in
such participants severance multiple as specified in the Plan, as well as continued welfare benefits equivalent to those available to a similar executive who is still employed by the Company, for the number of months in such participants
severance multiple as specified in the Plan, subject to certain contribution payments and other conditions. A qualifying participant will also receive payment of all unpaid base salary, bonus or other amount accrued through his or her termination
date. In addition, subject to certain conditions, if a participants employment is terminated by the Company or any of its affiliates during the six-month period prior to, and in connection with, a change in control, then such participant is
entitled to payment of the severance benefits and accrued rights described above. Under the terms of the Plan, and subject to satisfaction of the conditions therein, the named executive officers participating in the Plan would be entitled to the
following payments upon a qualifying termination of employment based on their current base salaries: Mr. Davidson: $637,500; Mr. Dickson: $531,250; and Mr. Fudge: $625,000. The Plan was filed as Exhibit 10.3 to our Current Report on
Form 8-K filed on March 9, 2012.

On March 20, 2012, the special committee composed of independent and disinterested
members our Board of Directors approved a one-time cash retention payment of $100,000 to Mr. Davidson. The retention payment is designed to encourage Mr. Davidson to continue to focus on the best interests of our stockholders during the
pendency of our going-private transaction discussed in the paragraph above. Subject to Mr. Davidsons continued employment, the retention payment is payable following the earlier of (i) the Effective Time of the Merger (as defined in
the Merger Agreement) and (ii) the date of our entry into an agreement with respect to a Superior Proposal (as defined in the Merger Agreement).

On the first business day in January of each year, non-employee Board members who have served on the
Board for at least one year also receive option grants covering 20,000 shares pursuant to the provisions of the automatic option grant program under our 2008 Stock Incentive Plan. In addition, our non-employee directors are entitled to receive a fee
in the amount of $2,000 for each Board meeting attended in person ($1,000 if attended via telephone) and $1,500 for each committee meeting attended in person ($750 if attended via telephone).

Compensation Risk Management

Our management has assessed our compensation policies and practices for all employees, including our named executive officers, to determine whether they encourage excessive risk taking. The Committee
reviewed managements assessments and concluded that these policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company. In doing so, the Committee considered various features of our
compensation policies and practices that discourage excessive or unnecessary risk taking, as presented by management.

|Item 13. | Certain Relationships and Related Transactions, and Director Independence
|-------- | -------------------------------------------------------------------------

Policies and Procedures for Approval of Related Person Transactions

The
charter of our Audit Committee requires that our Audit Committee review and approve all related person transactions. In determining whether to approve or ratify such a related person transaction, the Audit Committee follows our written policy
governing related person transactions and takes into account, among other factors it deems appropriate, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar
circumstances and the extent of the related persons interest in the transaction. The Audit Committee will generally approve only those related person transactions that are in the best interests of our company and our stockholders.

Certain Employee Relationships

Since May 2006, we have employed Jim Garn, the brother of Douglas F. Garn, our Vice Chairman, as our Senior Director, Sales Operations. For 2011, Jim Garn received cash compensation totaling $245,030,
which includes: (a) an annual base salary of $208,316, (b) a discretionary bonus in the amount of $33,714, and (c) a $3,000 matching contribution under our 401(k) plan. Also, on September 9, 2011, Jim Garn received an award of
20,000 stock options with an exercise price of $15.71. These stock options vest over a six year period, with 20% vesting on the second anniversary of the date of grant, and 10% vesting upon the completion of each of the next eight six-month periods
of employment.

Since September 2007, Chris Garn, the brother of Douglas F. Garn, our Vice Chairman, has
been employed by Quest or one of its wholly-owned subsidiaries, most recently as a Territory Account Manager. For 2011, Chris Garn received cash compensation totaling $159,469, which includes: (a) an annual base salary of $110,280,
(b) commission payments totaling $45,189, (c) an employee referral award totaling $1,000, and (d) retirement plan contributions totaling $3,000. In addition, Chris Garn participated in our 2011 sales club trip with a cost to the
Company allocated at $2,872, including related tax gross-up benefits.

Change in Control, Retention Payments

As discussed above under the caption Potential Payments upon Termination or Change in Control, on March 8, 2012, we
entered into an agreement to become a private company. In connection with this transaction, our Board of Directors adopted a Change in Control Severance Plan in which, of our named executive officers, Messrs. Davidson, Dickson and Fudge are
participants. In addition, the special committee of our Board of Directors approved a cash retention payment for Mr. Davidson. Please see the discussion under Potential Payments upon Termination or Change in Control for additional
details.

Other Relationships

We have entered into indemnification agreements with our executive officers and our directors containing provisions that may require us, among other things, to indemnify them against certain liabilities
that may arise by reason of their status or service as officers or directors, other than liabilities arising from willful misconduct of a culpable nature, and to advance expenses incurred as a result of any proceeding against them as to which they
could be indemnified.

We believe that all of the transactions set forth above were made on terms no less favorable to us than
could have been otherwise obtained from unaffiliated third parties.

audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services, and may be subject to a specific budget. The
independent registered public accounting firm and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this
pre-approval policy, and the related amounts of fees for services performed. The Audit Committee may also pre-approve particular services on a case-by-case basis. All Audit Fees, Audit-Related Fees, Tax Fees and All Other Fees for 2011 and 2010
described above were pre-approved by the Audit Committee.
