EX-10.4

THIS EMPLOYMENT AGREEMENT (the “Agreement”) is made as of August 15, 2013 (“Effective Date”), by and among QualityTech, LP, a Delaware limited partnership (the “Company”), QualityTech GP, LLC, a Delaware limited liability company and general partner of the Company (together with any successor general partner of the Company, the “General Partner”), Quality Technology Services, LLC, a Delaware limited liability company and an affiliate of the Company (“QTS LLC”), and Chad L.

WHEREAS, QTS LLC desires to employ Executive as Chief Executive Officer (“CEO”) of the Company, and the General Partner desires to appoint Executive as its CEO, and Executive desires to accept such employment and appointment, on the terms set forth below.

NOW, THEREFORE, in consideration of the mutual promises, covenants and agreements set forth herein, the parties hereto agree as follows:

1.2 Term. The period of employment of the Executive by the Company shall, subject to earlier termination as provided in this Agreement, commence upon the date hereof (the “Effective Date”) and continue thereafter for a term (the “Term”) of three (3) years; provided, that the Term shall automatically renew for additional one (1)-year periods unless either QTS LLC or Executive gives notice of non-renewal at least ninety (90) days prior to expiration of the Term (as it may have been extended by any renewal period).

1.3 Service as an Employee. During the Term, Executive shall (a) perform all duties and obligations reasonably associated with the position of CEO of the General Partner and the Company, consistent with the Bylaws or other governing documents of the Company and the General Partner, as applicable, as in effect from time to time, and (b) perform such other duties reasonably associated with a senior executive officer of the business of the Company, the General Partner, QTS LLC and their subsidiaries and affiliates (the “Quality Companies”), including duties of an executive, managerial or administrative nature as shall be specified and designated from time to time by the Board (including the performance of services

for the board of directors or a comparable governing body of, any member of the Quality Companies without any additional compensation), subject, in all cases described in clauses (a) and (b), to the supervision and direction of the Board.

1.4 Service as a Director. During the Term, the General Partner agrees that Executive shall be nominated for election to and as Chairman of the Board at each annual meeting of the General Partner’s equityholders or other meeting of the General Partner’s equityholders at which directors are elected.

2.1 Salary. In consideration for Executive’s services hereunder, QTS LLC shall pay Executive an annual salary at the rate of not less than $550,000 per year during each of the years of the Term, payable in accordance with QTS LLC’s regular payroll schedule from time to time (less any deductions required for Social Security, state, federal and local withholding taxes, and any other authorized or mandated similar withholdings). The annual salary shall be reviewed by the Compensation Committee of the Board (the “Compensation Committee”), or, if there is none, the Board, no less frequently than annually. Executive’s salary may be adjusted upward upon annual review, but shall not be decreased.

2.2 Bonus.

The Board may award discretionary bonuses in addition to performance bonuses.

2.3 Equity Award. Executive previously has received a one-time award of 500,000 Class O LTIP Units in QualityTech Employee Pool, LLC (the “Equity Award”). The Equity Award is subject to a four (4)-year vesting schedule and will become 100% vested upon either the occurrence of a “Change of Control” as defined in the QualityTech, LP 2010 Equity Incentive Plan or as otherwise provided in this Agreement. The Equity Awards are in the form of partnership “profits interest” units and, accordingly, require Executive to complete a form Section 83(b) election. Additional equity awards may be made in accordance with the Company’s policies and as deemed appropriate by the Compensation Committee.

3.1 Vacation. Executive shall be entitled to the greater of twenty-five (25) days of paid vacation or at least the equivalent paid vacation provided to other executives of the Company, the General Partner and QTS LLC, for each calendar year of the Term in accordance with the general policies of the Company and QTS LLC applicable to other senior executives of the Company, the General Partner and QTS LLC. Unused vacation shall carry over, if at all, in accordance with the general policies of the Company and QTS LLC as the same shall be in effect from time to time. For the avoidance of doubt, any days on which Executive works remotely or otherwise works from a location outside of Executive’s normal work location shall not be deemed to constitute vacation days to which Executive is entitled by virtue of this Section 3.1.

3.2 Employee Benefits. Executive shall receive all group insurance and retirement plan benefits and any other benefits on the same basis as are available to other senior executives of the Company, the General Partner and QTS LLC under the personnel policies in effect from time to time, and Executive shall be provided individual life and disability insurance benefits on substantially the same terms as apply to the Company’s and the General Partner’s top executives. Executive shall receive all other such fringe benefits as the Company, the General Partner and QTS LLC may offer to other senior executives generally under personnel policies in effect from time to time, such as health and disability insurance coverage and paid sick leave. Executive’s Family shall be covered under the Company’s health insurance plan, or, to the extent the same is not so permitted by law or the terms of such health insurance plans, Company shall pay or reimburse Executive for the cost of substantially similar coverage during the Term and as otherwise provided below following the Termination Date. For purposes of this Agreement, Executive’s “Family” shall include Executive’s spouse, children and legal dependents. To the extent the same is not so permitted by law or the terms of its health insurance plans, the Company shall provide health insurance to Executive’s father, mother, sister and the children or legal dependents of Executive’s sister (the “Extended Family”) with coverage commensurate with that offered to employees of the Company, provided, however, that Executive shall reimburse the Company for such coverage of Executive’s Extended Family in an amount equal to the insurance premium cost incurred by the Company plus the amount paid by the Company for the self-insured portion of such coverage, if any, up to but not in excess of the self-insured cap for such coverage (“Extended Family Coverage”). The Company shall notify Executive of the amount that Executive must reimburse the Company for such Extended Family Coverage, and Executive shall pay such amount by December 31 of the calendar year following the calendar year in which such Extended Family Coverage was provided.

3.3 Reimbursement for Expenses. Executive shall be reimbursed for all documented reasonable expenses incurred by Executive in the performance of his duties set forth in Section 1.3 and in furtherance of the business of the Quality Companies, including those for administrative support set forth below, in accordance with the reimbursement policies in effect from time to time. Any reimbursement under this Section 3.3 that is taxable to Executive shall be made by December 31 of the calendar year following the calendar year in which Executive incurred the expense.

3.4 Administrative Support. Executive shall be provided with administrative support commensurate with Executive’s position in the Company and Executive’s duties set forth in Section 1.3, in addition to executive support services applicable to other senior executives of the Company. The Company shall make available to Executive the services of a full-time assistant who may assist the Executive in Company and personal matters. In addition, Executive may from time to time seek assistance from two Company employees agreed upon by Executive and the Company for personal accounting and financial matters. To the extent that Executive utilizes other employees for matters unrelated to Company business, such arrangements will be in accordance with established procedures, including reimbursement of the reasonable value associated with any material use. In the event Executive’s use of other Company employees is expected to become material, Executive shall notify the Company’s Chief Financial Officer, Chief Operating Officer or General Counsel (“Executive Leader”) and the Executive Leader shall, in the sole discretion of the Executive Leader, determine whether such employee is able to accommodate Executive’s request. If the Executive Leader determines such employee is capable of completing Executive’s request, the Executive Leader will establish a written procedure for Executive’s use of such employee and Executive shall comply with such procedure, including reimbursement of the reasonable value associated with such use. If the Executive Leader determines such employee is not capable of completing Executive’s request, the Executive Leader will notify the Executive and recommend a path forward in writing, including, if necessary, the use of an outside vendor. Executive’s use of Company employees from time to time pursuant to this Section 3.4 shall not individually or in the aggregate constitute grounds for termination with Cause as defined in Section 4.1.2 of this Agreement unless Executive shall have refused to reimburse the Company for material use of an employee within thirty (30) days of an Executive Leader’s written demand.

4.1.1 Death or Disability. Executive’s employment with QTS LLC pursuant to this Agreement shall terminate immediately in the event of Executive’s death or Disability. “Disability” means any: (i) physical disability or impairment, (ii) mental disability or impairment, (iii) illness or (iv) injury, (x) that meets the definition of disability provided in applicable long-term disability insurance coverage extended to Executive by the

Company, if any, or (y) if no such insurance coverage is provided, that in the good faith judgment of the Board, prevents or would prevent Executive from performing his duties and obligations under this Agreement or participating effectively and actively in the management of the business of the Quality Companies for more than three consecutive months or for more than 90 days in any 180-day period.

4.1.2 Cause. QTS LLC shall have the right to terminate Executive’s employment by giving written notice of such termination to Executive upon the occurrence of any one or more of the following events (which, for purposes of this Agreement, shall constitute “Cause”):

Except as provided in Section 4.1.1 of this Agreement, any termination of Executive by the Company for any reason, including without limitation, a termination for alleged failures of performance, shall be deemed a termination without Cause, unless it is established that the reason for the termination was the occurrence of an event constituting Cause.

It shall be a condition precedent to QTS LLC’s right to terminate Executive’s employment for Cause under clauses (a) or (c) above that Cause be established as follows: (i) QTS LLC shall have first given Executive written notice stating with reasonable specificity the act(s) on which such termination is premised within twenty (20) days after the party providing such notice becomes aware or reasonably should have become aware of such act, and (ii) the Board by affirmative vote of at least three-fourths of its members (other than Executive if then serving as a member of the Board) find that the act alleged to be Cause constitutes Cause, has not been cured or remedied within thirty (30) days after receipt of such notice, and provided, such act is of such a nature that it

cannot with due diligence be cured within the time required, Executive shall not have commenced, or shall not thereafter diligently prosecute to completion, all steps necessary to cure such act alleged to be Cause within a reasonable period of time.

4.1.3 Good Reason. Executive may terminate his employment under this Agreement by giving written notice to QTS LLC upon the occurrence of any one or more of the following events (which, for purposes of this Agreement, shall constitute “Good Reason”):

It shall be a condition precedent to Executive’s right to terminate his employment for Good Reason that (a) he shall have first given the Board written notice stating with reasonable specificity the act(s) on which such termination is premised within ninety (90) days after Executive becomes aware of such act(s), (b) if such act(s) is susceptible of cure or remedy, it has not been cured or remedied within thirty (30) days after receipt of such notice, and Executive has terminated his employment within twelve (12) months after the occurrence of the event giving rise to Good Reason.

4.1.4 Any Other Reason. Notwithstanding anything to the contrary herein, QTS LLC shall have the right to terminate Executive’s employment under this Agreement at any time without Cause by giving written notice of such termination to Executive, and Executive shall have the right to terminate Executive’s employment under this Agreement at any time without Good Reason by giving written notice of such termination to QTS LLC. Any notice by Executive hereunder shall be given at least ninety (90) days in advance of such termination. Any notice by Company shall be given at least ninety (90) days in advance of such termination.

4.2 Termination Date. Except as provided in Section 4.1.1 with respect to Executive’s death or Disability, any termination under Section 4.1 shall be effective on the termination of the applicable notice period following receipt of notice by Executive or QTS LLC, as the case may be, of such termination or upon such other later date as may be provided herein or specified by QTS LLC or Executive in the notice (the “Termination Date”).

4.3.1 Termination with Cause or without Good Reason. In the event that Executive’s employment is terminated by QTS LLC with Cause or by Executive without Good Reason, QTS LLC shall pay, in a lump sum in cash within twenty (20) days after the Termination Date or on such earlier date required by applicable law (i) all Accrued Obligations to Executive, and (ii) any performance bonus or discretionary bonus under Section 2.2 that has been earned or declared for a bonus period ending before the Termination Date but not paid before the Termination Date. For purposes of this Agreement, the term “Accrued Obligations” means the sum of (a) Executive’s salary hereunder through the Termination Date to the extent not theretofore paid; (b) the amount of any accrued but unused vacation pay; and (c) any business expense reimbursements incurred by Executive as of the Termination Date and submitted for reimbursement, in each case, consistent with the policy for such reimbursements, within ten (10) days following the Termination Date.

4.3.2 Termination without Cause or with Good Reason. In the event that Executive’s employment is terminated by QTS LLC without Cause or by Executive for Good Reason:

QTS LLC’s delivery of any notice under Section 1.2 of this Agreement that the Agreement will not be renewed and any subsequent termination of Executive’s employment at the expiration of such Term of the Agreement shall not be considered a termination without Cause, and Executive shall not be entitled to any payments or benefits under this Section 4.3.2 under such circumstance.

4.3.3 Termination Due to Death or Disability. In the event that Executive’s employment is terminated due to Executive’s death or Disability, QTS LLC shall pay Executive the following:

4.3.4 Termination upon Change in Control. In the event that Executive’s employment is terminated following a Change in Control, the following provisions shall apply:

(1) QTS LLC shall pay all Accrued Obligations to Executive in a lump sum in cash within twenty (20) days after the Termination Date or on such earlier date required by law;

(2) QTS LC shall pay to Executive, in a lump sum in cash within twenty (20) days after the Termination Date or on such earlier date

required by law, any performance bonus or discretionary bonus under Section 2.2 that has been earned or declared for a bonus period ending before the Termination Date but not paid before the Termination Date;

(3) If not previously vested in full, the Equity Award and any other equity awards granted to Executive following the date hereof shall fully vest as of the Termination Date;

(4) QTS LLC shall pay to Executive, in a lump sum in cash on the first payroll date following sixty (60) days after the Termination Date, an amount equal to three (3) times Executive’s annual salary as in effect on the date of the Triggering Event or on the date on which the Change in Control occurs, whichever is higher;

(5) QTS LLC shall pay to Executive, in a lump sum in cash on the first payroll date following sixty (60) days after the Termination Date an amount equal to three (3) times Executive’s Annual Bonus (as defined below) for the year in which the termination occurs;

(6) QTS LLC shall, to the extent permitted by law or the terms of such health insurance plans, continue to cover Executive and Executive’s Family under the Quality Companies’ health insurance plans that covered such individuals immediately prior to the Termination Date for up to twenty-four (24) months following the Termination Date, or, to the extent the same is not so permitted, pay or reimburse the cost of substantially similar coverage for Executive and his Family for up to twenty-four (24) months following the Termination Date. To the extent the same is not so permitted by law or the terms of its health insurance plans, the Company shall provide Extended Family Coverage to Executive’s Extended Family for up to twenty-four (24) months following the Termination Date, and Executive shall reimburse the Company for such Extended Family Coverage in the manner provided in Section 3.2. Any reimbursement under this Section 4.3.4(a)(6) that is taxable to Executive or any of his Family members shall be made (subject to the provisions of such health care plans that may require earlier payment) by December 31 of the calendar year following the calendar year in which Executive or any member of Executive’s Family incurred the expense. Executive shall provide appropriate HIPPA releases necessary to determine cost and reimbursement requirements associated with Family and Extended Family coverage.

(7) QTS LLC shall provide Executive, at QTS LLC’s expense, with outplacement services and support, the scope and provider of which will be selected by Executive, for a period of one (1) year following the date of the Triggering Event.

(1) Prior to any initial public offering of securities of the General Partner (“IPO”), (i) any transaction or series of transactions pursuant to which ownership of at least 30% of the combined voting power of the Company’s outstanding voting securities as of the Effective Date is transferred (through merger, transfer of units or other similar transaction) to persons or entities other than the persons or entities (“Incumbent Partners”) who were partners of the Company as of the Effective Date, or (ii) any transfer of direct or indirect ownership or control of QTS LLC or its assets by the Company, and

A. Any “person” as such term is used in Section 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (other than the General Partner or the Company, any Incumbent Partner, any trustee or other fiduciary holding securities under any employee benefit plan of the General Partner, the Company or QTS LLC or any corporation owned, directly or indirectly, by the partners of the Company in substantially the same proportion as their ownership of interests in the Company), is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the General Partner or the Company representing 30% or more of the then combined voting power of the then outstanding voting securities of the General Partner or the Company, as the case may be;

B. During any period of twelve (12) consecutive months, individuals who at the beginning of such period constitute the Board and any new director (other than a director designated by a person who has entered into an agreement with the General Partner or the Company to effect a transaction described in clause (A), (C) or (D) hereof) whose election by the Board or nomination for election by the General Partner’s equityholders was approved by a vote of at least a majority of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or actual threatened solicitation of proxies or consents by or on behalf of a person other than the Board, cease for any reason to constitute at least a majority of the Board;

C. The equityholders of the General Partner or the Partners of the Company approve a merger or consolidation of the General Partner or the Company with any other entity or approve the issuance of voting securities in connection with a merger or consolidation of the General Partner or the Company (or any direct or indirect subsidiary

thereof) pursuant to applicable exchange requirements, other than (A) a merger or consolidation which would result in (x) the voting securities of the General Partner outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving or parent entity) more than 70% of the combined voting power of the voting securities of the General Partner or such surviving or parent entity outstanding immediately after such merger or consolidation and (y) the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving or parent entity) more than 70% of the combined voting power of the voting securities of the Company or such surviving or parent entity outstanding immediately after such merger or consolidation, or (B) a merger or consolidation effected to implement a recapitalization of the General Partner or the Company (or similar transaction) in which no “person” (as defined above) is or becomes the beneficial owner, directly or indirectly, of securities of the General Partner or the Company representing 30% or more of the then combined voting power of the General Partner’s or the Company’s, as the case may be, then outstanding voting securities; or

D. The consummation of the sale or disposition by the General Partner or the Company of all or substantially all of the assets of the General Partner or the Company, as the case may be (or any transaction or series of transactions within a period of twelve months ending on the date of the last sale or disposition having a similar effect), or any transfer of direct or indirect ownership or control of QTS LLC or its assets by the Company.

For the avoidance of doubt, an IPO shall not constitute a Change in Control and no reorganization of the Company or its ownership in contemplation of an IPO shall constitute a Change in Control.

(c) “Triggering Event” will be deemed to have occurred if (i) within two (2) years from the date on which the Change in Control occurred, QTS LLC terminates the employment of Executive, other than in the case of a termination for Cause, or (ii) within two (2) years from the date on which the Change in Control occurred, the Executive terminates his employment for Good Reason.

(d) “Executive’s Annual Bonus” means, for purposes of Section 4.3.2, Section 4.3.3 and this Section 4.3.4, Executive’s annual bonus (i) at the time of the Termination Date for purposes of Section 4.3.2 and Section 4.3.3, and (ii) with regard to a Triggering Event, the annual bonus in effect on the Termination Date or on the date on which the Change in Control occurred, whichever is higher, calculated on the basis of the target bonus available to Executive and the assumption that all performance goals are satisfied at a 100% achievement level by QTS LLC and Executive in the year in which such Termination without Cause or for Good Reason, Triggering Event or such Change in Control, as the case may be, occurred.

For the avoidance of doubt, in the event of a Change of Control and a Triggering Event under circumstances entitling Executive to payments and benefits under this Section 4.3.4, such payments and benefits shall be in lieu of payments and benefits under Section 4.3.2, and Executive shall not be entitled to any compensation or benefits under Section 4.3.2.

4.3.5 Waiver and Release Agreement. In consideration of the severance payments and other benefits described in Section 4.3.2, Section 4.3.3 and Section 4.3.4, to which severance payments and benefits Executive would not otherwise be entitled, and as a precondition to Executive becoming entitled to such severance payments and other benefits under this Agreement, Executive agrees to execute and deliver to QTS LLC on or before the sixtieth (60^th) day after the applicable Termination Date a waiver and general release of claims in favor of the Quality Companies, their respective predecessors and successors, and all of the respective current or former directors, officers, employees, shareholders, partners, members, agents or representatives of any of the foregoing, in a form reasonably satisfactory to QTS LLC, that has become effective in accordance with its terms, and for which any revocation periods applicable to such release shall have expired on or prior to the sixtieth (60^th) day following Executive’s Termination Date. If Executive fails to execute and deliver such release agreement on or before the sixtieth (60^th) day following the applicable Termination Date, if any revocation period applicable to such release has not expired on or before the sixtieth (60^th) day following Executive’s Termination Date or if Executive revokes such release as provided therein, QTS LLC shall have no obligation to provide any of the severance payments and other benefits described in Section 4.3.2, Section 4.3.3 or Section 4.3.4 other than any Accrued Obligations.

4.4 Required Delay For Certain Deferred Compensation and Section 409A. In the event that any compensation with respect to Executive’s termination is “deferred compensation” within the meaning of Section 409A of the Code and the regulations promulgated thereunder (“Section 409A”), and Executive is determined to be a “specified employee,” as defined in Section 409A(a)(2)(B)(i) of the Code, payment of such compensation shall be delayed as required by Section 409A. Such delay shall last six (6) months from the date of Executive’s termination, except in the event of Executive’s death. Within twenty (20) business days following the end of such six (6)-month period, or, if earlier, Executive’s death, QTS LLC shall make a catch-up payment to Executive equal to the total amount of such payments that would have been made during the six (6)-month period but for this Section 4.4. Such catch-up payment shall bear simple interest at the prime rate of interest as published by the Wall Street Journal’s bank survey as of the first day of the six (6)-month period, which such interest shall be paid with the catch-up payment. Wherever payments under this Agreement are to be made in installments, each such installment shall be deemed to be a separate payment for purposes of Section 409A. The Executive will be deemed to have a Termination Date for purposes of determining the timing of any payments or benefits hereunder that are classified as deferred compensation only upon a “separation from service” within the meaning of Section 409A. Any

amount that the Executive is entitled to be reimbursed under this Agreement will be reimbursed to the Executive as promptly as practical and in any event not later than the last day of the calendar year after the calendar year in which the expenses are incurred and any right to reimbursement or in-kind benefits will not be subject to liquidation or exchange for another benefit. Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty (30) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of QTS LLC.

4.5 Non-Exclusivity of Rights. Nothing in this Agreement shall prevent or limit Executive’s continuing or future participation in any plan, program, policy or practice provided by the General Partner, Company or QTS LLC, and for which Executive may qualify, nor shall anything herein limit or otherwise affect such rights as Executive may have under any other contract or agreement with the General Partner, Company or QTS LLC at or subsequent to the Termination Date, which shall be payable in accordance with such plan, policy, practice or program or contract or agreement, except as explicitly modified by this Agreement.

4.6 No Set-Off or Mitigation. QTS LLC’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any setoff, counterclaim, recoupment, defense, or other claim, right or action that QTS LLC may have against Executive or others, except to the extent of the mitigation and setoff provisions provided for in this Agreement. In no event shall Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to Executive under any of the provisions of this Agreement, and such amounts shall not be reduced whether or not Executive obtains other employment.

4.7 Excise Tax-Related Provisions. The payments and benefits that Executive may be entitled to receive under this Agreement and other payments and benefits that Executive is or may be entitled to receive under other plans, agreements and arrangements (which, together with the benefits provided under this Agreement, are referred to as “Payments”), may constitute Parachute Payments (as defined below) that are subject to Sections 280G and 4999 of the Code. As provided in this Section 4.7, the Parachute Payments will be reduced if, and only to the extent that, a reduction will allow Executive to receive a greater Net After Tax Amount (as defined below) than Executive would receive absent a reduction.

4.7.1 The Accounting Firm (as defined below) will first determine the amount of any Parachute Payments that are payable to the Executive. The Accounting Firm also will determine the Net After Tax Amount attributable to the Executive’s total Parachute Payments.

4.7.2 The Accounting Firm will next determine the largest amount of Payments that may be made to the Executive without subjecting Executive to tax under Section 4999 of the Code (the “Capped Payments”). Thereafter, the Accounting Firm will determine the Net After Tax Amount attributable to the Capped Payments.

4.7.3 Executive will receive the total Parachute Payments or the Capped Payments, whichever provides Executive with the higher Net After Tax Amount. If Executive will receive the Capped Payments, the total Parachute Payments will be adjusted by first reducing the amount of any cash benefits under this Agreement or any other plan, agreement or arrangement (with the source of the reduction to be directed by the Company) and then by reducing the amount of any noncash benefits under this Agreement or any other plan, agreement or arrangement (with the source of the reduction to be directed by the Company). The Accounting Firm will notify Executive and the Company if it determines that the Parachute Payments must be reduced to the Capped Payments and will send Executive and the Company a copy of its detailed calculations supporting that determination.

4.7.4 As a result of the uncertainty in the application of Sections 280G and 4999 of the Code at the time that the Accounting Firm makes its determinations under this Section 4.7, it is possible that amounts will have been paid or distributed to Executive that should not have been paid or distributed under this Section 4.7 (“Overpayments”), or that additional amounts should be paid or distributed to the Executive under this Section 4.7 (“Underpayments”). If the Accounting Firm determines, based on either the assertion of a deficiency by the Internal Revenue Service against the Company or the Executive, which assertion the Accounting Firm believes has a high probability of success or controlling precedent or substantial authority, that an Overpayment has been made, the Executive must repay to the Company, without interest, the amount of the Overpayment; provided, however, that no amount will be payable by the Executive to the Company unless, and then only to the extent that, the payment would either reduce the amount on which the Executive is subject to tax under Section 4999 of the Code or generate a refund of tax imposed under Section 4999 of the Code. If the Accounting Firm determines, based upon controlling precedent or substantial authority, that an Underpayment has occurred, the Accounting Firm will notify the Executive and the Company of that determination and the amount of that Underpayment will be paid to the Executive promptly by the Company.

For purposes of this Section 4.7, the term “Accounting Firm” means the independent accounting firm engaged by the Company immediately before a Change in Control. For purposes of this Section 4.7, the term “Net After Tax Amount” means the amount of any Parachute Payments or Capped Payments, as applicable, net of taxes imposed under Sections 1, 3101(b) and 4999 of the Code and any State or local income taxes applicable to Executive on the date of payment. The determination of the Net After Tax Amount shall be made using the highest combined effective rate imposed by the foregoing taxes on income of the same character as the Parachute Payments or Capped Payments, as applicable, in effect on the date of payment. For purposes of this Section 4.7, the term “Parachute Payment” means a payment that is described in Section 280G(b)(2) of the Code, determined in accordance with Section 280G of the Code and the regulations promulgated or proposed thereunder.

(1) Obligation to Maintain Confidentiality. Executive acknowledges that, by reason of Executive’s employment by the Company and position with the General Partner, Executive will have access to confidential matters relating to the names, addresses, buying habits and other special information regarding past and present customers, as well as potential customers with whom the Company has established material contacts and entered into active negotiations for the sale of products or services, employees and suppliers of the Company; customer contracts and transactions or price lists of the Company; products, services, programs and processes sold, licensed or developed by the Company; technical data, plans and specifications; financial and/or marketing data known only by the Company and respecting the conduct of the present or future phases of business of the Company; computer programs, systems and/or software developed by the Company; ideas, inventions, trademarks, trade secrets, business information, know-how, processes, designs, redesigns, discoveries and developments of the Company; and information considered confidential by any customers or suppliers of the Company (collectively, “Confidential Information”) of the Quality Companies.
