Issuers or any Guarantor that secures any Secured Bank Indebtedness that is not already subject to the Lien under the Security Documents, except to the extent such property is excluded from the Collateral pursuant to the Security Documents because

 “Fixed Charge
Coverage Ratio” means, with respect to any Person for any period, the ratio of EBITDA of such Person for such period to the Fixed Charges of such Person for such period. In the event that QD LLC or any of the Restricted Subsidiaries Incurs,
repays, repurchases or redeems any Indebtedness (other than in the case of any Qualified Receivables Financing, in which case interest expense shall be computed based upon the average daily balance of such Indebtedness during the applicable period)
or issues, repurchases or redeems Disqualified Stock or Preferred Stock subsequent to the commencement of the period for which the Fixed Charge Coverage Ratio is being calculated but prior to the event for which the calculation of the Fixed Charge
Coverage Ratio is made (the “Calculation Date”), then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect to such Incurrence, repayment, repurchase or redemption of Indebtedness, or such issuance,
repurchase or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period; provided that QD LLC may elect pursuant to an Officer’s Certificate delivered to the Trustee
to treat all or any portion of the commitment under any Indebtedness as being Incurred at such time, in which case any subsequent Incurrence of Indebtedness under such commitment shall not be deemed, for purposes of this calculation, to be an
Incurrence at such subsequent time. 
 For purposes of making the computation referred to above, Investments, acquisitions,
dispositions, mergers, amalgamations, consolidations and discontinued operations (as determined in accordance with GAAP), in each case with respect to an operating unit of a business, and any operational changes that QD LLC or any Restricted
Subsidiary has determined to make and/or made during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Calculation Date shall be calculated on a pro forma basis assuming
that all such Investments, acquisitions, dispositions, mergers, amalgamations, consolidations, discontinued operations and other operational changes (and the change of any associated fixed charge obligations and the change in EBITDA resulting
therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into QD LLC or any Restricted Subsidiary since the
beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation, amalgamation, discontinued operation or operational change, in each case with respect to an operating unit of a business, that would have
required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, discontinued operation, merger,
amalgamation, consolidation or operational change had occurred at the beginning of the applicable four-quarter period. If since the beginning of such period any Restricted Subsidiary is designated an Unrestricted Subsidiary or any Unrestricted
Subsidiary is designated a Restricted Subsidiary, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such designation had occurred at the beginning of the applicable four-quarter period.

 For purposes of this definition, whenever pro forma effect is to be given to any event, the pro forma
calculations shall be made in good faith by a responsible financial or accounting officer of QD LLC. Any such pro forma calculation may include adjustments appropriate, in the reasonable good faith determination of QD LLC as set forth in an
Officer’s 

  
 16 

 
Certificate, to reflect (1) operating expense reductions and other operating improvements or synergies reasonably expected to result from the applicable event, and (2) all adjustments
of the nature used in connection with the calculation of “Consolidated EBITDA” as set forth in footnote (3) to the “Summary Financial and Other Operating Data of QDI” under “Summary” in the Offering Memorandum to
the extent such adjustments, without duplication, continue to be applicable to such four-quarter period. 
 If any Indebtedness
bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into
account any Hedging Obligations applicable to such Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined
by a responsible financial or accounting officer of QD LLC to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under
a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate
based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as QD LLC may designate.

 For purposes of this definition, any amount in a currency other than U.S. dollars will be converted to U.S. dollars based on
the average exchange rate for such currency for the most recent twelve-month period immediately prior to the date of determination in a manner consistent with that used in calculating EBITDA for the applicable period. 

“Fixed Charges” means, with respect to any Person for any period, the sum, without duplication, of:

 (2)
all cash dividend payments (excluding items eliminated in consolidation) on any series of Preferred Stock or Disqualified Stock of such Person and its Restricted Subsidiaries.

significant segment of the accounting profession, which are in effect on the Issue Date. For the purposes of this Indenture, the term “consolidated” with respect to any Person shall mean such Person consolidated with its Restricted

date of determination, and (b) the amount of such Indebtedness of such other Person; 
 provided, however, that
notwithstanding the foregoing, Indebtedness shall be deemed not to include (1) Contingent Obligations Incurred in the ordinary course of business and not in respect of borrowed money; (2) deferred or prepaid revenues; (3) purchase
price holdbacks in respect of a portion of the purchase price of an asset to satisfy warranty or other unperformed obligations of the respective seller; or (4) Obligations under or in respect of Qualified Receivables Financing. 

Notwithstanding anything in this Indenture to the contrary, Indebtedness shall not include, and shall be calculated without giving effect
to, the effects of Statement of Financial Accounting Standards No. 133 and related interpretations to the extent such effects would otherwise increase or decrease an amount of Indebtedness for any purpose under this Indenture as a result of
accounting for any embedded derivatives created by the terms of such Indebtedness; and any such amounts that would have constituted Indebtedness under this Indenture but for the application of this sentence shall not be deemed an Incurrence of
Indebtedness under this Indenture.

 41 

 
Additional Notes registered, or any transfer of such Global Note in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Note or a nominee
thereof; and 
 (4) if applicable, that such Additional Notes that are not Transfer Restricted Notes shall not be
issued in the form of Initial Notes as set forth in Exhibit A, but shall be issued in the form of Exchange Notes as set forth in Exhibit B. 
 If any of the terms of any Additional Notes are established by action taken pursuant to a resolution of the Board of Directors, a copy of an appropriate record of such action shall be certified by the
Secretary or any Assistant Secretary of QD LLC and delivered to the Trustee at or prior to the delivery of the Officer’s Certificate or the indenture supplemental hereto setting forth the terms of the Additional Notes. 

The Initial Notes, including any Additional Notes, may, at the Issuers’ option, be treated as a single class for all purposes under
this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. 
 SECTION 2.02.
Form and Dating. Provisions relating to the Initial Notes and the Exchange Notes are set forth in Appendix A, which is hereby incorporated in and expressly made a part of this Indenture. The (i) Initial Notes and the
Trustee’s certificate of authentication and (ii) any Additional Notes (if issued as Transfer Restricted Notes) and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit A hereto, which
is hereby incorporated in and expressly made a part of this Indenture. The (i) Exchange Notes and the Trustee’s certificate of authentication and (ii) any Additional Notes issued other than as Transfer Restricted Notes and the
Trustee’s certificate of authentication shall each be substantially in the form of Exhibit B hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have notations, legends or endorsements
required by law, stock exchange rule, agreements to which the Issuers or any Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuers). Each Note shall be dated the
date of its authentication. The Notes shall be issuable only in registered form without interest coupons and in denominations of $2,000 and any integral multiples of $1,000 in excess of $2,000. 

SECTION 2.03. Execution and Authentication. The Trustee shall authenticate and make available for delivery upon a written
order of the Issuers signed by one Officer (a) Initial Notes for original issue on the date hereof in an aggregate principal amount of $225,000,000, (b) subject to the terms of this Indenture, Additional Notes in an aggregate principal
amount to be determined at the time of issuance and specified therein and (c) the Exchange Notes for issue in a Registered Exchange Offer pursuant to the Registration Rights Agreement for a like principal amount of Initial Notes exchanged

authenticated, the date on which the original issue of Notes is to be authenticated, the registered holder of each of the Notes and delivery instructions and whether the Notes are to be Initial Notes or Exchange Notes. Notwithstanding anything to
the contrary in this Indenture or Appendix A, any issuance of Additional Notes after the Issue Date shall be in a principal amount of at least $2,000 and integral multiples of $1,000 in excess of $2,000. 

  
 42 

  
 One Officer shall sign
the Notes for the Issuers by manual or facsimile signature. 
 If an Officer whose signature is on a Note no longer holds that
office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless. 
 A Note shall not be valid until
an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 

The Trustee may appoint one or more authenticating agents reasonably acceptable to the Issuers to authenticate the Notes. Any such
appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuers. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 

SECTION 2.04. Registrar and Paying Agent. 
 (a) The Issuers shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) an office or agency
where Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuers may have one or more co-registrars and one or more additional paying
agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Issuers initially appoint the Trustee as Registrar, Paying Agent and
the Notes Custodian with respect to the Global Notes. 
 (b) The Issuers may enter into an appropriate agency agreement with any
Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuers shall notify the Trustee in writing of the
name and address of any such agent. If the Issuers fail to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. QD LLC or any of its
domestically organized Wholly-Owned Subsidiaries may act as Paying Agent or Registrar. 
 (c) The Issuers may remove any
Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor as
evidenced by an appropriate agreement entered into by the Issuers and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or
Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Issuers and the Trustee; provided, however, that the Trustee may
resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08. 

  
 43 

  
 SECTION 2.05.
Paying Agent to Hold Money in Trust. Prior to each due date of the principal of and interest on any Note, the Issuers shall deposit with each Paying Agent (or if QD LLC or a Wholly-Owned Subsidiary is acting as Paying Agent, segregate and
hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due. The Issuers shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying Agent
shall hold in trust for the benefit of holders or the Trustee all money held by a Paying Agent for the payment of principal of and interest on the Notes, and shall notify the Trustee of any default by the Issuers in making any such payment. If QD
LLC or a Wholly-Owned Subsidiary of QD LLC acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it in trust for the benefit of the Persons entitled thereto. The Issuers at any time may require a Paying Agent to pay
all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section, a Paying Agent shall have no further liability for the money delivered to the Trustee. 

SECTION 2.06. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of holders. If the Trustee is not the Registrar, the Issuers shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five Business Days before each Interest Payment Date and at
such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of holders. 
 SECTION 2.07. Transfer and Exchange. The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer and in compliance
with Appendix A. When a Note is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if its requirements therefor are met. When Notes are presented to the Registrar with a
request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Issuers shall execute
and the Trustee shall authenticate Notes at the Registrar’s request. The Issuers may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this
Section. The Issuers shall not be required to make, and the Registrar need not register, transfers or exchanges of Notes selected for redemption (except, in the case of Notes to be redeemed in part, the portion thereof not to be redeemed) or of any
Notes for a period of 15 days before a selection of Notes to be redeemed. 
 Prior to the due presentation for registration of
transfer of any Note, the Issuers, the Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal
of and interest, if any, on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Issuers, the Guarantors, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

  
 44 

  
 Any holder of a
beneficial interest in a Global Note shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by (a) the holder of such Global
Note (or its agent) or (b) any holder of a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry. 

All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled
to the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange. 
 The Trustee shall have no
obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or
among Depository participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by
the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 None of the Trustee, Registrar or Paying Agent shall have any responsibility for any actions taken or not taken by the Depository. 
 SECTION 2.08. Replacement Notes. If a mutilated Note is surrendered to the Registrar or if the holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuers
shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the holder (a) satisfies the Issuers or the Trustee within a reasonable time after
such holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuers or the Trustee prior to the Note being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Issuers, such
holder shall furnish an indemnity bond sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, a Paying Agent and the Registrar from any loss or liability that any of them may suffer if a Note is replaced and
subsequently presented or claimed for payment. The Issuers and the Trustee may charge the holder for their expenses in replacing a Note (including without limitation, attorneys’ fees and disbursements in replacing such Note). In the event any
such mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Issuers in their discretion may pay such Note instead of issuing a new Note in replacement thereof. 

Every replacement Note is an additional obligation of the Issuers. 

The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes. 

  
 45 

  
 SECTION 2.09.
Outstanding Notes. Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. Subject to
Section 13.06, a Note does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Note. 

If a Note is replaced pursuant to Section 2.08 (other than a mutilated Note surrendered for replacement), it ceases to be
outstanding unless the Trustee and the Issuers receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to
Section 2.08. 
 If a Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date
or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is prohibited from paying such money to the
holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 

SECTION 2.10. [Intentionally omitted.] 
 SECTION 2.11. Cancellation. The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and each Paying Agent shall forward to the Trustee any Notes surrendered to them
for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Notes in accordance with its customary
procedures. The Issuers may not issue new Notes to replace Notes they have redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Notes in place of canceled Notes other than pursuant to the terms of this
Indenture. 
 SECTION 2.12. Defaulted Interest. If the Issuers default in a payment of interest on the Notes, the Issuers
shall pay the defaulted interest then borne by the Notes (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Issuers may pay the defaulted interest to the Persons who are holders on a subsequent special record
date. The Issuers shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail or cause to be mailed to each affected holder a notice that states the special
record date, the payment date and the amount of defaulted interest to be paid. 
 SECTION 2.13. CUSIP Numbers, ISINs, Etc.
The Issuers in issuing the Notes may use CUSIP numbers, ISINs and “Common Code” numbers (if then generally in use) and, if so, the Trustee shall use CUSIP numbers, ISINs and “Common Code” numbers in notices of redemption as a
convenience to holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Notes or as contained in any notice of a redemption that reliance may be placed
only on the other identification numbers printed on the Notes and that any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers shall advise the Trustee of any change in the CUSIP numbers, ISINs and
“Common Code” numbers.

 SECTION 2.14.
Calculation of Principal Amount of Notes. The aggregate principal amount of the Notes, at any date of determination, shall be the principal amount of the Notes at such date of determination. With respect to any matter requiring consent, waiver,
approval or other action of the holders of a specified percentage of the principal amount of all the Notes, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of
determination, of Notes, the holders of which have so consented, by (b) the aggregate principal amount, as of such date of determination, of the Notes then outstanding, in each case, as determined in accordance with the preceding sentence,
Section 2.09 and Section 13.06 of this Indenture. Any such calculation made pursuant to this Section 2.14 shall be made by the Issuers and delivered to the Trustee pursuant to an Officer’s Certificate. 

ARTICLE III

 48 

 
final sentence of paragraph 5 of the Notes. Upon surrender to the Paying Agent, such Notes shall be paid at the redemption price stated in the notice, plus accrued interest, to, but not
including, the redemption date; provided, however, that if the redemption date is after a regular Record Date and on or prior to the Interest Payment Date, the accrued interest shall be payable to the holder of the redeemed Notes registered
on the relevant Record Date. Failure to give notice or any defect in the notice to any holder shall not affect the validity of the notice to any other holder. 
 SECTION 3.07. Deposit of Redemption Price. With respect to any Notes, prior to 10:00 a.m., New York City time, on the redemption date, the Issuers shall deposit with the Paying Agent (or, if
QD LLC or a Wholly-Owned Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Notes or portions thereof to be redeemed on that date other than Notes or
portions of Notes called for redemption that have been delivered by the Issuers to the Trustee for cancellation. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption so long as the
Issuers have deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest on, the Notes to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this
Indenture.

provided that any subsequent issuance or transfer of any Capital Stock or any other event which results in any Restricted Subsidiary that holds such shares of Preferred Stock of another Restricted Subsidiary ceasing to be a Restricted
Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except to QD LLC or another Restricted Subsidiary) shall be deemed, in each case, to be an issuance of shares of Preferred Stock not permitted by this clause (viii);

 56 

  
 For purposes of determining compliance
with this Section 4.03: 
 (i) in the event that an item of Indebtedness, Disqualified Stock or Preferred
Stock (or any portion thereof) meets the criteria of more than one of the categories of permitted Indebtedness described in clauses (i) through (xxv) above or is entitled to be Incurred pursuant to Section 4.03(a), QD LLC shall, in
its sole discretion, classify or reclassify, or later divide, classify or reclassify, such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) in any manner that complies with this Section 4.03; and 

(ii) at the time of Incurrence, QD LLC will be entitled to divide and classify an item of Indebtedness in more than one of
the types of Indebtedness described in Section 4.03(a) and (b) without giving pro forma effect to the Indebtedness Incurred pursuant to Section 4.03(b) when calculating the amount of Indebtedness that may be Incurred pursuant
to Section 4.03(a). 
 Accrual of interest, the accretion of accreted value, the payment of interest or dividends in the
form of additional Indebtedness, Disqualified Stock or Preferred Stock, as applicable, amortization of original issue discount, the accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of
fluctuations in the exchange rate of currencies will not be deemed to be an Incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this Section 4.03. Guarantees of, or obligations in respect of letters of credit
relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included in the determination of such amount of Indebtedness; provided that the Incurrence of the Indebtedness
represented by such guarantee or letter of credit, as the case may be, was in compliance with this Section 4.03. 
 For
purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the
relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term debt, or first committed or first Incurred (whichever yields the lower U.S. dollar equivalent), in the case of revolving credit debt;
provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal
amount of such Indebtedness being refinanced. 
 (c) Notwithstanding any other provision of this Section 4.03, the maximum
amount of Indebtedness that QD LLC and the Restricted Subsidiaries may Incur pursuant to this Section 4.03 shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate
of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the
currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing.

accordance with Section 4.03 so long as: 
 (A) the principal amount (or accreted value, if applicable) of

as otherwise permitted under clause (xv) of Section 4.03(b), 
 (C) such Indebtedness has a final
scheduled maturity date equal to or later than the earlier of (x) the final scheduled maturity date of the Subordinated Indebtedness being so redeemed, repurchased, acquired or retired and (y) 91 days following the last maturity date of
any Notes then outstanding, and 
 (D) such Indebtedness has a Weighted Average Life to Maturity at the time
Incurred which is not less than the shorter of (x) the remaining Weighted Average Life to Maturity of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired and (y) the Weighted Average Life to Maturity
that would result if all payments of principal on the Subordinated Indebtedness being redeemed, repurchased, defeased, acquired or retired that were due on or after the date that is one year following the last maturity date of any Notes then

the extent contributed to QD LLC) or QD LLC’s Restricted Subsidiaries after the Issue Date;

any present or former employees, directors, officers or consultants of QD LLC, any Restricted Subsidiary or the direct or indirect parents of QD LLC in connection with a repurchase of Equity Interests of QD LLC or any of its direct or indirect
parents will not be deemed to constitute a Restricted Payment for purposes of this Section 4.04 or any other provision of this Indenture;

Ratio of at least 2.00 to 1.00; 
 (vii) Investments in Unrestricted Subsidiaries having an aggregate Fair Market

Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such designation

 63 

  
 SECTION 4.05.
Dividend and Other Payment Restrictions Affecting Subsidiaries. QD LLC shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any
consensual encumbrance or consensual restriction on the ability of any Issuer or Restricted Subsidiary to: 
 (a) (i) pay
dividends or make any other distributions to QD LLC or any Restricted Subsidiary (1) on its Capital Stock; or (2) with respect to any other interest or participation in, or measured by, its profits; or (ii) pay any Indebtedness owed
to QD LLC or any of Restricted Subsidiary; 
 (b) make loans or advances to QD LLC or any Restricted Subsidiary; or 

(c) sell, lease or transfer any of its properties or assets to QD LLC or any Restricted Subsidiary; 

except in each case for such encumbrances or restrictions existing under or by reason of: 

(1) contractual encumbrances or restrictions in effect on the Issue Date, including pursuant to the Credit Agreement and
the other Credit Agreement Documents and the Subordinated Notes due 2013; 
 (2) this Indenture, the Notes (and
any Exchange Notes and guarantees thereof); 
 (3) applicable law or any applicable rule, regulation or order;

 (4) any agreement or other instrument of a Person acquired by QD LLC or any Restricted Subsidiary which was in
existence at the time of such acquisition (but not created in contemplation thereof or to provide all or any portion of the funds or credit support utilized to consummate such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired; 

(5) contracts or agreements for the sale of assets, including any restriction with respect to a Restricted Subsidiary
imposed pursuant to an agreement entered into for the sale or disposition of the Capital Stock or assets of such Restricted Subsidiary; 
 (6) Secured Indebtedness otherwise permitted to be Incurred pursuant to Sections 4.03 and 4.12 that limit the right of the debtor to dispose of the assets securing such Indebtedness;

 (8) customary provisions in joint venture agreements and other similar agreements entered into in the ordinary course of business;

 (10)
customary provisions contained in leases, licenses and other similar agreements entered into in the ordinary course of business;

Receivables Subsidiary; 
 (12) other Indebtedness, Disqualified Stock or Preferred Stock (a) of QD LLC or
any Restricted Subsidiary that is a Guarantor or a Foreign Subsidiary or (b) of any Restricted Subsidiary that is not a Guarantor or a Foreign Subsidiary so long as such encumbrances and restrictions contained in any agreement or instrument
will not materially affect the Issuers’ ability to make anticipated principal or interest payments on the Notes (as determined in good faith by QD LLC), provided that in the case of each of clauses (a) and (b), such Indebtedness,
Disqualified Stock or Preferred Stock is permitted to be Incurred subsequent to the Issue Date pursuant to Section 4.03; 
 (13) any Restricted Investment not prohibited by Section 4.04 and any Permitted Investment; or 
 (14) any encumbrances or restrictions of the type referred to in clauses (a), (b) and (c) above imposed by any amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (13) above; provided that such amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings are, in the good faith judgment of QD LLC, no more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such
amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing. 
 For purposes of
determining compliance with this Section 4.05, (i) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a
restriction on the ability to make distributions on Capital Stock and (ii) the subordination of loans or advances made to QD LLC or a Restricted Subsidiary to other Indebtedness Incurred by QD LLC or any such Restricted Subsidiary shall not be
deemed a restriction on the ability to make loans or advances. 

  
 65 

  
 SECTION 4.06.
Asset Sales. 
 (a) QD LLC shall not, and shall not permit any of the Restricted Subsidiaries to, cause or make an Asset
Sale, unless (x) QD LLC or any Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value (as determined in good faith by QD LLC) of the assets sold or otherwise
disposed of, and (y) at least 75% of the consideration therefor received by QD LLC or such Restricted Subsidiary, as the case may be, is in the form of Cash Equivalents; provided that the amount of: 

(i) any liabilities (as shown on QD LLC’s or a Restricted Subsidiary’s most recent balance sheet or in the notes
thereto) of QD LLC or a Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes or any Guarantee) that are assumed by the transferee of any such assets or that are otherwise cancelled or terminated in
connection with the transaction with such transferee, 
 (ii) any notes or other obligations or other securities
or assets received by QD LLC or such Restricted Subsidiary from such transferee that are converted by QD LLC or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received), and 

(iii) any Designated Non-cash Consideration received by QD LLC or any Restricted Subsidiary in such Asset Sale having an
aggregate Fair Market Value (as determined in good faith by QD LLC), taken together with all other Designated Non-cash Consideration received pursuant to this Section 4.06(a)(iii) that is at that time outstanding, not to exceed the greater of
7.5% of Total Assets and $25.0 million at the time of the receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect
to subsequent changes in value), 
 shall be deemed to be Cash Equivalents for the purposes of this Section 4.06(a). 

(b) Within 365 days after QD LLC’s or any Restricted Subsidiary’s receipt of the Net Proceeds of any Asset Sale, QD LLC or such
Restricted Subsidiary may apply the Net Proceeds from such Asset Sale, at its option: 
 (i) to repay
(A) Indebtedness constituting First Priority Lien Obligations and other senior Indebtedness that is secured by a Lien permitted under this Indenture (“Pari Passu Indebtedness”) (and, if the Indebtedness repaid is revolving
credit Indebtedness, to correspondingly reduce commitments with respect thereto), (B) Indebtedness of a Restricted Subsidiary that is not a Guarantor, (C) Obligations under the Notes or (D) other Pari Passu Indebtedness
(provided that if an Issuer or any Guarantor shall so reduce Obligations under Pari Passu Indebtedness that does not constitute First Priority Lien Obligations, the Issuers will equally and ratably reduce Obligations under the Notes pursuant
to Section 3.01 through open-market purchases (provided that such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all
holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued 

  
 66 

 
and unpaid interest and Additional Interest, if any, the pro rata principal amount of Notes), in each case other than Indebtedness owed to QD LLC or an Affiliate of QD LLC; or 

(ii) to make an Investment in any one or more businesses (provided that if such Investment is in the form of the
acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of QD LLC), assets, or property or capital expenditures, in each case (a) used or useful in a Similar Business or (b) that
replace the properties and assets that are the subject of such Asset Sale. 
 In the case of Section 4.06(b)(ii), a binding
commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment until the 18 month anniversary of the date of the receipt of such Net Proceeds; provided that in the event such binding commitment is
later canceled or terminated for any reason before such Net Proceeds are so applied, QD LLC or such Restricted Subsidiary enters into another binding commitment (a “Second Commitment”) within six months of such cancellation or
termination of the prior binding commitment; provided, further, that QD LLC or such Restricted Subsidiary may only enter into a Second Commitment under the foregoing provision one time with respect to each Asset Sale and to the extent
such Second Commitment is later cancelled or terminated for any reason before such Net Proceeds are applied, or is not applied prior to such 18 month anniversary, then such Net Proceeds shall constitute Excess Proceeds. 

Pending the final application of any such Net Proceeds, QD LLC or such Restricted Subsidiary may temporarily reduce Indebtedness under a
revolving credit facility, if any, or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture. Any Net Proceeds from any Asset Sale that are not applied as provided and within the time period set forth in the first sentence
of this Section 4.06(b) (it being understood that any portion of such Net Proceeds used to make an offer to purchase Notes, as described in clause (i) of this Section 4.06(b), shall be deemed to have been invested whether or not such
offer is accepted) will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Issuers shall make an offer to all holders of Notes (and, at the option of the Issuers, to
holders of any Pari Passu Indebtedness) (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes (and such Pari Passu Indebtedness), that is at least $2,000 and an integral multiple of $1,000 in excess thereof that
may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof (or, in the event such Pari Passu Indebtedness was issued with significant original issue discount, 100% of the accreted
value thereof), plus accrued and unpaid interest and Additional Interest, if any (or, in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness), to the date
fixed for the closing of such offer, in accordance with the procedures set forth in this Section 4.06. The Issuers will commence an Asset Sale Offer with respect to Excess Proceeds within ten (10) Business Days after the date that Excess
Proceeds exceed $10.0 million by mailing the notice required pursuant to the terms of Section 4.06(f), with a copy to the Trustee. To the extent that the aggregate amount of Notes (and such Pari Passu Indebtedness) tendered pursuant to an Asset
Sale Offer is less than the Excess Proceeds, QD LLC may use any remaining Excess Proceeds for any purpose that is not prohibited by this Indenture. If the aggregate principal amount of Notes (and such Pari Passu Indebtedness) surrendered by holders
thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased in the manner described in Section 4.06(e). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

  
 67 

  
 (c) The Issuers will
comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to an Asset Sale Offer. To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, The Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations described in this Indenture by virtue thereof. 
 (d) Not later than the date upon which written notice of an Asset
Sale Offer is delivered to the Trustee as provided above, QD LLC shall deliver to the Trustee an Officer’s Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant
to which such Asset Sale Offer is being made and (iii) the compliance of such allocation with the provisions of Section 4.06(b). On such date, the Issuers shall also irrevocably deposit with the Trustee or with a paying agent (or, if an
Issuer or a Wholly-Owned Restricted Subsidiary is acting as the Paying Agent, segregate and hold in trust) an amount equal to the Excess Proceeds to be invested in Cash Equivalents, as directed in writing by QD LLC, and to be held for payment in
accordance with the provisions of this Section 4.06. Upon the expiration of the period for which the Asset Sale Offer remains open (the “Offer Period”), the Issuers shall deliver to the Trustee for cancellation the Notes or
portions thereof that have been properly tendered to and are to be accepted by the Issuers. The Trustee (or the Paying Agent, if not the Trustee) shall, on the date of purchase, mail or deliver payment to each tendering holder in the amount of the
purchase price. In the event that the Excess Proceeds delivered by the Issuers to the Trustee are greater than the purchase price of the Notes tendered, the Trustee shall deliver the excess to QD LLC immediately after the expiration of the Offer
Period for application in accordance with Section 4.06. 
 (e) Holders electing to have a Note purchased shall be required
to surrender the Note, with an appropriate form duly completed, to the Issuers at the address specified in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Trustee an
Issuer receives not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered by the holder for purchase and
a statement that such holder is withdrawing his election to have such Note purchased. If at the end of the Offer Period more Notes (and such Pari Passu Indebtedness) are tendered pursuant to an Asset Sale Offer than the Issuers are required to
purchase, selection of such Notes for purchase shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed, or if such Notes are not so listed, on a pro rata
basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that no Notes of $2,000 or less shall be purchased in part. Selection of such
Pari Passu Indebtedness shall be made pursuant to the terms of such Pari Passu Indebtedness. 
 (f) Notices of an Asset Sale
Offer shall be mailed by first class mail, postage prepaid, at least 30 but not more than 60 days before the purchase date to each holder of Notes at 

  
 68 

 
such holder’s registered address. If any Note is to be purchased in part only, any notice of purchase that relates to such Note shall state the portion of the principal amount thereof that
has been or is to be purchased. 
 SECTION 4.07. Transactions with Affiliates. 

(a) QD LLC shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, make any payment to, or sell,
lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction or series of transactions, contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any Affiliate of QD LLC (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration in excess of $5.0 million, unless:

 SECTION 4.08. Change of Control. 

(a) Upon a Change of Control, each holder shall have the right to require the Issuers to repurchase all or any part of such holder’s
Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the holders of record on the relevant Record Date to receive
interest due on the relevant Interest Payment Date), in accordance with the terms contemplated in this Section 4.08; provided, however, that notwithstanding the occurrence of a Change of Control, the Issuers shall not be obligated
to purchase any Notes pursuant to this Section 4.08 in the event that it has exercised its right to redeem such Notes in accordance with Article III of this Indenture. In the event that at the time of such Change of Control the terms of the
Bank Indebtedness restrict or prohibit the repurchase of Notes pursuant to this Section 4.08, then prior to the mailing of the notice to the holders provided for in Section 4.08(b) but in any event within 30 days following any Change of
Control, the Issuers shall (i) repay in full all Bank Indebtedness or, if doing so will allow the purchase of Notes, offer to repay in full all Bank Indebtedness and repay the Bank Indebtedness of each lender and/or noteholder who has accepted
such offer, or (ii) obtain the requisite consent under the agreements governing the Bank Indebtedness to permit the repurchase of the Notes as provided for in Section 4.08(b). 

  
 71 

  
 (b) Within 30 days
following any Change of Control, except to the extent that the Issuers have exercised their right to redeem the Notes in accordance with Article III of this Indenture, the Issuers shall mail a notice (a “Change of Control Offer”) to
each holder with a copy to the Trustee stating: 
 (i) that a Change of Control has occurred and that such holder
has the right to require the Issuers to repurchase such holder’s Notes at a repurchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to the date of
repurchase (subject to the right of the holders of record on the relevant Record Date to receive interest on the relevant Interest Payment Date); 
 (ii) the circumstances and relevant facts and financial information regarding such Change of Control; 
 (iii) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and 

(iv) the instructions determined by the Issuers, consistent with this Section 4.08, that a holder must follow in
order to have its Notes purchased. 
 (c) holders electing to have a Note purchased shall be required to surrender the Note,
with an appropriate form duly completed, to the Issuers at the address specified in the notice at least three Business Days prior to the purchase date. The holders shall be entitled to withdraw their election if the Trustee or the Issuers receive
not later than one Business Day prior to the purchase date a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered for purchase by the holder and a statement that
such holder is withdrawing his election to have such Note purchased. Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered. 

(d) On the purchase date, all Notes purchased by the Issuers under this Section shall be delivered to the Trustee for cancellation, and
the Issuers shall pay the purchase price plus accrued and unpaid interest to the holders entitled thereto. 
 (e) A
Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer. 

(f) Notwithstanding the foregoing provisions of this Section, the Issuers shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in Section 4.08 applicable to a Change of Control Offer made by the Issuers and
purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. 
 (g) Notes repurchased by the
Issuers pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be retired and canceled at the option of the Issuers. Notes purchased by a third party pursuant to the preceding clause (f) will have
the status of Notes issued and outstanding. 

  
 72 

  
 (h) At the time the
Issuers delivers Notes to the Trustee which are to be accepted for purchase, the Issuers shall also deliver an Officer’s Certificate stating that such Notes are to be accepted by the Issuers pursuant to and in accordance with the terms of this
Section 4.08. A Note shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering holder. 

(i) Prior to any Change of Control Offer, the Issuers shall deliver to the Trustee an Officer’s Certificate stating that all
conditions precedent contained herein to the right of the Issuers to make such offer have been complied with. 
 (j) The Issuers
shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section. To the extent that the
provisions of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this
Section by virtue thereof. 
 SECTION 4.09. Compliance Certificate. QD LLC shall deliver to the Trustee within 120
days after the end of each fiscal year of QD LLC, beginning with the fiscal year ending on December 31, 2010, an Officer’s Certificate stating that in the course of the performance by the signer of his or her duties as an Officer of QD LLC
he or she would normally have knowledge of any Default and whether or not the signer knows of any Default that occurred during such period. If he or she does, the certificate shall describe the Default, its status and what action QD LLC is taking or
proposes to take with respect thereto. QD LLC also shall comply with Section 314(a)(4) of the TIA. Except with respect to receipt of payments of principal and interest on the Notes and any Default or Event of Default information contained in
the Officer’s Certificate delivered to it pursuant to this Section 4.09, the Trustee shall have no duty to review, ascertain or confirm the Issuers’ compliance with or the breach of any representation, warranty or covenant made in
this Indenture. 
 SECTION 4.10. Further Instruments and Acts. Upon request of the Trustee, the Issuers shall
execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 
 SECTION 4.11. Future Subsidiary Guarantors. QD LLC shall cause each Wholly-Owned Restricted Subsidiary that is a Domestic Subsidiary (unless such Subsidiary is a Receivables Subsidiary or a
Domestic Subsidiary that is wholly owned by one or more Foreign Subsidiaries and created to enhance the tax efficiency of the Issuer and its Subsidiaries) and that guarantees any Indebtedness of QD LLC or any of the Guarantors to execute and deliver
to the Trustee a supplemental indenture substantially in the form of Exhibit D pursuant to which such Restricted Subsidiary shall guarantee the Issuers’ Obligations under the Securities and this Indenture on the same second-priority secured
basis, as well as to execute and deliver a joinder to the Intercreditor Agreement and to execute and deliver to the Trustee the Security Documents necessary to cover such Restricted Subsidiary to become a guarantor and take all actions to perfect
Liens created thereunder. 

  
 73 

  
 SECTION 4.12.
Liens. 
 (a) QD LLC shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly,
create, Incur or suffer to exist any Lien (the “Initial Lien”) on any asset or property of QD LLC or such Restricted Subsidiary of QD LLC, or any income or profits therefrom, or assign or convey any right to receive income
therefrom, whether owned at the Issue Date or thereafter acquired, (i) that secures any Indebtedness of any Person (other than Permitted Liens) unless the notes are equally and ratably secured with (or on a senior basis to, in the case of
Subordinated Indebtedness) such Indebtedness so long as such Indebtedness is so secured and (ii) that secures any First-Priority Lien Obligation of QD LLC or any Guarantor (but subject to limitations as described in Article XI and the Security
Documents) without effectively providing that the notes or the applicable Guarantee, as the case may be, shall be granted a second-priority security interest (subject to Permitted Liens) upon the assets or property constituting the collateral for
such First-Priority Lien Obligations; provided, however, that if granting such second-priority security interest requires the consent of a third party, QD LLC will use commercially reasonable efforts to obtain such consent with respect to the
second-priority security interest for the benefit of the Trustee on behalf of the holders of the notes; provided further, however, that if such third party does not consent to the granting of such second-priority security interest after the use of
commercially reasonable efforts, QD LLC will not be required to provide such security interest. 
 (b) Any Lien created for the
benefit of the holders of the Notes pursuant to clause (i) of Section 4.12(a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

 (c) For purposes of determining compliance with this covenant, (A) a Lien securing an item of Indebtedness need not be
permitted solely by reference to one category of permitted Liens described in clauses (1) through (28) of the definition of “Permitted Liens” or pursuant to Section 4.12(a) but may be permitted in part under any combination
thereof and (B) in the event that a Lien securing an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of one or more of the categories of permitted Liens described in clauses
(1) through (28) of the definition of “Permitted Liens” or pursuant to Section 4.12(a), QD LLC shall, in its sole discretion, classify or reclassify, or later divide, classify or reclassify, such Lien securing such item of
Indebtedness (or any portion thereof) in any manner that complies with this covenant and will only be required to include the amount and type of such Lien or such item of Indebtedness secured by such Lien in one of the clauses of the definition of
“Permitted Liens” and such Lien securing such item of Indebtedness will be treated as being Incurred or existing pursuant to only one of such clauses or pursuant to Section 4.12(a). 

(d) With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the Incurrence of such
Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any
accrual of interest, the accretion of accreted value, the amortization of original issue 

  
 74 

 
discount, the payment of interest in the form of additional Indebtedness with the same terms or in the form of common stock of QD LLC, the payment of dividends on Preferred Stock in the form of
additional shares of Preferred Stock of the same class, accretion of original issue discount or liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or
increases in the value of property securing Indebtedness described in clause (3) of the definition of “Indebtedness”. 
 SECTION 4.13. After-Acquired Property. Upon the acquisition by the Issuers or any Guarantor of any First-Priority After-Acquired Property, the Issuers or such Guarantor shall execute and
deliver such mortgages, deeds of trust, security instruments, financing statements, certificates and opinions of counsel as shall be reasonably necessary to vest in the Trustee, a perfected security interest, subject only to Permitted Liens, in such
First-Priority After-Acquired Property and to have such First Priority After-Acquired Property (but subject to limitations as described in Article XI and the Security Documents) added to the Collateral, and thereupon all provisions of this Indenture
relating to the Collateral shall be deemed to relate to such First Priority After-Acquired Property to the same extent and with the same force and effect; provided, however, that if granting such second-priority security interest in such
First-Priority After-Acquired Property requires the consent of a third party, QD LLC will use commercially reasonable efforts to obtain such consent with respect to the second-priority interest for the benefit of the Trustee on behalf of the holders
of the notes; provided further, however, that if such third party does not consent to the granting of such second-priority security interest after the use of such commercially reasonable efforts, the Issuers or such Guarantor, as the case may
be, will not be required to provide such security interest. 
 SECTION 4.14. Maintenance of Office or Agency.

 (a) The Issuers shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or
Registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuers in respect of the Notes and this Indenture may be served. The Issuers shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuers shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee as set forth in Section 13.02. 
 (b) The Issuers may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission shall in any manner relieve the Issuers of their obligation to maintain an office or agency for such purposes. The Issuers shall give prompt written notice to
the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
 (c)
The Issuers hereby designate the Corporate Trust Office of the Trustee or its agent as such office or agency of the Issuers in accordance with Section 2.04. 

  
 75 

  
 SECTION 4.15.
Amendment of Security Documents. The Issuers will not amend, modify or supplement, or permit or consent to any amendment, modification or supplement of, the Security Documents in any way that would be adverse to the holders of the Notes in
any material respect, except as set forth in Article XI or as permitted under Article IX. 
 SECTION 4.16. Covenant
Suspension. If on any date following the Issue Date, (i) the Notes have Investment Grade Ratings from both Rating Agencies, and (ii) no Default has occurred and is continuing under this Indenture, then, beginning on that day and
continuing at all times thereafter regardless of any subsequent changes in the rating of the Notes (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant
Suspension Event”), and subject to the provisions of the following paragraph, the QD LLC and the Restricted Subsidiaries shall not be subject to Sections 4.03, 4.04, 4.05, 4.06, 4.07 and 5.01(a)(iv) (collectively the “Suspended
Covenants”). 
 In the event that the QD LLC and the Restricted Subsidiaries are not subject to the Suspended Covenants
under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned
to the Notes below an Investment Grade Rating, then QD LLC and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. 

On each Reversion Date, all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be
classified as having been Incurred or issued pursuant to Section 4.03(a) or 4.03(b) (to the extent such Indebtedness or Disqualified Stock or Preferred Stock would be permitted to be Incurred or issued thereunder as of the Reversion Date and
after giving effect to Indebtedness Incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness or Disqualified Stock or Preferred Stock would not be so permitted to be Incurred or issued
pursuant to Section 4.03 such Indebtedness or Disqualified Stock or Preferred Stock will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.03(b)(iii). Calculations made after the
Reversion Date of the amount available to be made as Restricted Payments under Section 4.04 will be made as though Section 4.04 had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments
made during the Suspension Period will reduce the amount available to be made as Restricted Payments under Section 4.04(a). As described above, however, no Default or Event of Default will be deemed to have occurred on the Reversion Date as a
result of any actions taken by QD LLC or the Restricted Subsidiaries during the Suspension Period. 
 For purposes of
Section 4.06, on the Reversion Date, the unutilized Excess Proceeds amount will be reset to zero. 
 SECTION 4.17.
Maintenance of Insurance. QD LLC shall maintain, with financially sound and reputable insurance companies, insurance (subject to customary deductibles and retentions) in such amounts and against such risks as are customarily maintained by
similarly situated companies engaged in the same or similar businesses operating in the same or similar locations and cause Issuers and the Guarantors to be listed as insured and the Trustee to be listed as co-loss payee on property and property
casualty policies and as an additional 

  
 76 

 
insured on liability policies. Notwithstanding the foregoing, the Issuers and the Guarantors may self-insure with respect to such risks with respect to which companies of established reputation
in the same general line of business in the same general area usually self-insure. 
 SECTION 4.18. Liquidated Damages
Notice. In the event that the Issuers are required to pay Liquidated Damages to holders of Notes pursuant to the Registration Rights Agreement, the Issuers will provide written notice (“Liquidated Damages
Notice”) to the Trustee of its obligation to pay Liquidated Damages no later than fifteen days prior to the proposed payment date for the Liquidated Damages, and the Liquidated Damages Notice shall set forth the amount of Liquidated Damages
to be paid by the Issuers on such payment date. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the Liquidated Damages, or with respect to the nature, extent, or calculation of the
amount of Liquidated Damages owed, or with respect to the method employed in such calculation of the Liquidated Damages. 

SECTION 4.19. Further Collateral-Related Matters. Notwithstanding Section 4.12 and Section 4.13, the Issuers and
the Guarantors shall not be required to grant Liens securing the Notes and the Guarantees on (i) Transportation Equipment (as defined in the Security Documents) owned as of the Issue Date or acquired within 30 days thereafter or (ii) Owned
Real Property owned on the Issue Date. The Issuers and the Guarantors shall use their commercially reasonable efforts to cause to be granted to the Collateral Agent, within 60 days following the Issue Date, Mortgages (and any related Security
Documents) with respect to such Owned Real Property (in form substantially similar to those granted to the holders of First Priority Lien Obligations, with appropriate modifications to reflect the second-priority status of the Liens and the terms of
the Intercreditor Agreement), together with Opinions of Counsel, delivered to the Trustee in respect of the enforceability and validity of such Mortgages (and any related Security Documents), addressing customary matters (and containing customary
exceptions), and shall use commercially reasonable efforts to cause to be recorded or filed within such time period such Mortgages (and any related Security Documents) in such manner and in such places as is required by law to establish, perfect,
preserve and protect the Liens in favor of the Collateral Agent granted pursuant to the Mortgages (and any related Security Documents) and shall pay in full all taxes, fees and other charges payable in connection therewith. In connection therewith,
QD LLC shall (x) use commercially reasonable efforts to provide a title insurance policy or policies, or endorsements to existing policies, paid for by the Issuers, insuring the Lien of each such Mortgage (and any related Security Documents) as
a valid second Lien on such Mortgaged Properties described therein, free of any other Liens except Permitted Liens, together with such customary endorsements to any new policy or policies (including zoning endorsements where reasonably appropriate
and available), coinsurance and reinsurance as the Collateral Agent may reasonably request, and with respect to any such property located in a state in which a zoning endorsement is not available, a zoning compliance letter from the applicable
municipality in a form reasonably acceptable to the Collateral Agent, and (y) use commercially reasonable efforts to deliver to the Collateral Agent a copy of the ALTA/ACSM Land Title Surveys that were delivered with respect to each Mortgaged
Properties in connection with the First Lien Obligations and any “no change” affidavit reasonably required by the title company so as to enable the title company to issue coverage over all general survey exceptions and to issue all
endorsements reasonably requested by the Collateral Agent.

the Successor Holdco or any Restricted Subsidiary as a result of such transaction as having been Incurred by the Successor Holdco, or such Issuer or such Restricted Subsidiary at the time of such transaction) no Default shall have occurred and be
continuing; 
 (iv) immediately after giving pro forma effect to such transaction, as if such transaction

Successor Holdco or such Restricted Subsidiary at the time of such transaction), either 
 (A) the Successor
Holdco would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.03(a); or 

(B) the Fixed Charge Coverage Ratio for the Successor Holdco and its Restricted Subsidiaries would be greater than such

as the amount of Indebtedness of QD LLC and its Restricted Subsidiaries is not increased thereby. This Article V will not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among QD LLC and the Restricted
Subsidiaries. 
 (b) Subject to the provisions of Section 11.04, none of QD Capital or any Restricted Subsidiary that is a
Guarantor shall, and QD LLC shall not permit any of QD Capital or any Restricted Subsidiary that is a Guarantor to, consolidate, amalgamate or merge with or into or wind up into (whether or not such Issuer or Restricted Subsidiary is the surviving
Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, any Person unless:

obligations of QD Capital or such Restricted Subsidiary under this Indenture and the Notes or the Guarantee, as applicable, pursuant to a supplemental indenture or other documents or instruments in form reasonably satisfactory to the Trustee, or
(b) such sale or disposition or consolidation, amalgamation or merger is not in violation of Section 4.06 and does not constitute a sale, transfer, lease, conveyance or other disposition of all or substantially all of the assets of QD LLC;
and 
 (ii) the Successor (if other than such Issuer or Restricted Subsidiary) shall have delivered or caused to
be delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger or transfer and such supplemental indenture (if any) comply with this Indenture. 

  
 79 

  
 Except as otherwise
provided in this Indenture, the Successor (if other than QD Capital or such Restricted Subsidiary) will succeed to, and be substituted for, QD Capital or such Restricted Subsidiary under the Indenture and the Notes or the Guarantee, as applicable,
and QD Capital or such Restricted Subsidiary will automatically be released and discharged from its obligations under the Indenture and the Notes or its Guarantee, as applicable. Notwithstanding the foregoing, (1) QD Capital or a Restricted
Subsidiary that is a Guarantor may merge, amalgamate or consolidate with an Affiliate incorporated solely for the purpose of reincorporating QD Capital or such Subsidiary Guarantor in another state of the United States, the District of Columbia or
any territory of the United States so long as the amount of Indebtedness of such Issuer or such Restricted Subsidiary is not increased thereby and (2) a Restricted Subsidiary that is a Guarantor may merge, amalgamate or consolidate with QD LLC
or a Restricted Subsidiary that is a Guarantor. 
 In addition, notwithstanding the foregoing, a Restricted Subsidiary that is a
Guarantor may consolidate, amalgamate or merge with or into or wind up into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets (collectively, a “Transfer”) to QD
LLC or any Restricted Subsidiary that is a Guarantor. 
 QDI will not consolidate, amalgamate or merge with or into or wind up
into (whether or not QDI is the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, any Person unless: 

(1) either QDI or QD LLC (provided that if QD LLC is to be the surviving Person, then such transaction shall comply
with Section 5.01(a) or 5.01(b)) is the surviving Person or the Person formed by or surviving any such consolidation, amalgamation or merger (if other than QDI) or to which such sale, assignment, transfer, lease, conveyance or other disposition
will have been made is a corporation, partnership or limited liability company organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (QDI or such Person, as the case may be,
being herein called the “Successor Parent Guarantor”) and the Successor Parent Guarantor (if other than QDI) expressly assumes all the obligations of QDI under the Indenture and QDI’s Guarantee pursuant to a supplemental
indenture or other documents or instruments in form reasonably satisfactory to the Trustee; and 
 (2) the
Successor Parent Guarantor (if other than QDI) shall have delivered or caused to be delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger or transfer and such
supplemental indenture (if any) comply with this Indenture. 
 Except as otherwise provided in this Indenture, the Successor
Parent Guarantor (if other than QDI) will succeed to, and be substituted for, QDI under this Indenture and QDI’s Guarantee, and QDI will automatically be released and discharged from its obligations under this Indenture and such Guarantee.

 ARTICLE VI

 DEFAULTS AND REMEDIES 
 SECTION 6.01. Events of Default. An “Event of Default” occurs with respect to Notes if: 
 (a) there is a default in any payment of interest (including any additional interest) on any Note when the same becomes due and payable, and such default continues for a period of 30 days, 

(b) there is a default in the payment of principal or premium, if any, of any Note when due at its Stated Maturity, upon optional
redemption, upon required repurchase, upon declaration or otherwise, 
 (c) the failure by QD LLC or any Restricted Subsidiary
to comply for 60 days after notice with its other agreements contained in the Notes or this Indenture, 
 (d) the failure by QD
LLC or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay any Indebtedness (other than Indebtedness owing to QD LLC or a Restricted Subsidiary) within any applicable grace period
after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds $20.0 million or its foreign currency equivalent,

 (e) either QDI, QD LLC or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: 

(i) commences a voluntary case; 
 (ii) consents to the entry of an order for relief against it in an involuntary case; 
 (iii) consents to the appointment of a Custodian of it or for any substantial part of its property; or 
 (iv) makes a general assignment for the benefit of its creditors or takes any comparable action under any foreign laws relating to insolvency, 

(f) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(i) is for relief against either QDI, QD LLC or any Significant Subsidiary in an involuntary case; 

(ii) appoints a Custodian of either QDI, QD LLC or any Significant Subsidiary or for any substantial part of its property;
or 

  
 81 

  
 (iii)
orders the winding up or liquidation of either QDI, QD LLC or any Significant Subsidiary; 
 or any similar relief is granted
under any foreign laws and the order or decree remains unstayed and in effect for 60 days, 
 (g) failure by QD LLC or any
Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $20.0 million or its foreign currency equivalent (net of any amounts which are covered by
enforceable insurance policies issued by solvent carriers), which judgments are not discharged, waived or stayed for a period of 60 days, 
 (h) the Guarantee of QDI or any Guarantee of a Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) with respect to the notes ceases to be in full
force and effect (except as contemplated by the terms thereof) or QDI, QD LLC or any Guarantor that qualifies as a Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) denies or disaffirms its
obligations under the indenture or any Guarantee with respect to the notes and such Default continues for 10 days, 
 (i) unless
such Liens have been released in accordance with the provisions of the Security Documents, Liens in favor of the holders of the notes with respect to all or substantially all of the Collateral cease to be valid or enforceable, or any Issuer shall
assert or any Guarantor shall assert, in any pleading in any court of competent jurisdiction, that any such security interest is invalid or unenforceable and, in the case of any Subsidiary Guarantor, QD LLC fails to cause such Subsidiary Guarantor
to rescind such assertions within 30 days after QD LLC has actual knowledge of such assertions, or 
 (j) the failure by QDI,
the Issuers or any Subsidiary Guarantor to comply for 60 days after notice with its other agreements contained in the Security Documents except for a failure that would not be material to the holders of the notes and would not materially affect the
value of the Collateral taken as a whole (together with the defaults described in clause (8) the “security default provisions”). 
 The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 
 The term
“Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law. 
 However, a default under clause (c) or (j) above shall not constitute an Event of Default
until the Trustee or the holders of 25% in principal amount of outstanding Notes notify the Issuers of the default and the Issuers do not cure such default within the time specified in clauses (c) or (j) hereof after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” The Issuers shall 

  
 82 

 
deliver to the Trustee, within five (5) Business Days after the occurrence thereof, written notice in the form of an Officer’s Certificate of any event which is, or with the giving of
notice or the lapse of time or both would become, an Event of Default, its status and what action the Issuers are taking or propose to take with respect thereto. 
 SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(e) or 6.01(f) hereof with respect to QD LLC) occurs and is continuing, the
Trustee or the holders of at least 25% in principal amount of outstanding Notes by notice to the Issuers may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration,
such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(e) or (f) with respect to QD LLC occurs, the principal of, premium, if any, and interest on all the Notes will become
immediately due and payable without any declaration or other act on the part of the Trustee or any holders. The holders of a majority in principal amount of outstanding Notes may rescind any such acceleration with respect to the Notes and its
consequences. No such recission shall affect any subsequent Default or impair any right consequent thereto. 
 In the event of
any Event of Default specified in Section 6.01(d) above, such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the
Trustee or the holders of the Notes, if within 20 days after such Event of Default arose Issuers deliver an Officer’s Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has
been discharged or (y) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured,
it being understood that in no event shall an acceleration of the principal amount of the Notes as described above be annulled, waived or rescinded upon the happening of any such events. 

SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy at
law or in equity to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes, this Indenture or the Security Documents. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. To the extent required by law, all available remedies are cumulative. 
 SECTION 6.04. Waiver of Past
Defaults. Provided the Notes are not then due and payable by reason of a declaration of acceleration, the holders of a majority in principal amount of the Notes by written notice to the Trustee may waive an existing Default and its consequences
except (a) a Default in the payment of the principal of or interest on a Note, (b) a Default arising from the failure to redeem or purchase any Note when required pursuant to the terms of this Indenture or (c) a Default in respect of
a provision that under Section 9.02 cannot be amended without the consent of each holder affected. When a Default is waived, it is deemed 

  
 83 

 
cured and the Issuers, the Trustee and the holders will be restored to their former positions and rights under this Indenture, but no such waiver shall extend to any subsequent or other Default
or impair any consequent right. 
 SECTION 6.05. Control by Majority. The holders of a majority in principal amount
of Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture or, if the Trustee, being advised by counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine that the action or proceeding so directed would
involve the Trustee in personal liability or expense for which it is not adequately indemnified, or subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other holder or that would involve the Trustee
in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

 SECTION 6.06. Limitation on Suits. 
 (a) Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder may pursue any remedy with respect to this Indenture or the Notes unless: 

(i) such holder has previously given the Trustee notice that an Event of Default is continuing, 

(ii) holders of at least 30% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy,

 (iii) such holders have offered the Trustee security or indemnity satisfactory to the Trustee against any
loss, liability or expense, 
 (iv) the Trustee has not complied with such request within 60 days after the
receipt of the request and the offer of security or indemnity, and 
 (v) the holders of a majority in principal
amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period. 
 (b) A holder may not use this Indenture to prejudice the rights of another holder or to obtain a preference or priority over another holder. 

SECTION 6.07. Rights of the Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of
any holder to receive payment of principal of and interest on the Notes held by such holder, on or after the respective due dates expressed or provided for in the Notes, or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such holder. 

  
 84 

  
 SECTION 6.08.
Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuers or any other
obligor on the Notes for the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Notes) and the amounts provided for in Section 7.07.

 SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim, statements of interest
and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements and advances of the Trustee (including counsel, accountants, experts
or such other professionals as the Trustee deems necessary, advisable or appropriate)) and the holders allowed in any judicial proceedings relative to the Issuers, the Guarantors, their creditors or their property, shall be entitled to participate
as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the holders in any election of a trustee in bankruptcy or other Person
performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the
holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. 

SECTION 6.10. Priorities. Subject to the terms of the Intercreditor Agreement and the Security Documents, any money or
property collected by the Trustee pursuant to this Article VI and any other money or property distributable in respect of the Issuers’ or any Guarantor’s obligations under this Indenture after an Event of Default shall be applied in the
following order: 
 FIRST: to the Trustee for amounts due under Section 7.07; 

SECOND: to the holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably,
without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest, respectively; and 
 THIRD: to Issuers or, to the extent the Trustee collects any amount for any Guarantor, to such Guarantor. 
 The Trustee may fix a record date and payment date for any payment to the holders pursuant to this Section. At least 15 days before such record date, the Trustee shall mail to each holder and QD LLC a
notice that states the record date, the payment date and amount to be paid. 
 SECTION 6.11. Undertaking for Costs.
In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the

  
 85 

 
suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a holder pursuant to Section 6.07 or a suit by holders of
more than 10% in principal amount of the Notes. 
 SECTION 6.12. Waiver of Stay or Extension Laws. Neither Issuers
nor any Guarantor (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and the Issuers and the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. 
 ARTICLE VII

SECTION 7.01. Duties of Trustee. 
 (a) The Trustee, prior to the occurrence of an Event of Default with respect to the Notes and after the curing or waiving of all Events of Default which may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Indenture. If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and
skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
 (b) Except during the continuance of an Event of Default:

Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee (it being agreed that the permissive right
of the Trustee to do things enumerated in this Indenture shall not be construed as a duty); and 
 (ii) in the
absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements
of this Indenture. The Trustee shall be under no duty to make any investigation as to any statement contained in any such instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such
opinions. However, in the case of certificates or opinions required by any provision hereof to be provided to it, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture
(but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 

  
 86 

  
 (c) The Trustee may
not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(c) of this Section.

the document. 
 (b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion
of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officer’s Certificate or Opinion of Counsel. 
 (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. 

(d) The Trustee shall not be responsible or liable for any action it takes or omits to take in good faith which it believes to be
authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence. 

  
 87 

  
 (e) The Trustee may
consult with counsel of its own selection and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Notes shall be full and complete authorization and protection from liability in respect of any action
taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel. 
 (f)
The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or
document unless requested in writing to do so by the holders of not less than a majority in principal amount of the Notes at the time outstanding, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuers, personally or by agent or attorney, at the expense of the
Issuers and shall Incur no liability of any kind by reason of such inquiry or investigation. 
 (g) The Trustee shall be under
no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the holders pursuant to this Indenture, unless such holders shall have offered to the Trustee security or indemnity
satisfactory to the Trustee against the costs, expenses and liabilities which might be Incurred by it in compliance with such request or direction. 
 (h) The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its
capacities hereunder, and each agent, custodian and other Person employed to act hereunder. 
 (i) The Trustee shall not be
responsible or liable for any action taken or omitted by it in good faith at the direction of the holders of not less than a majority in principal amount of the Notes as to the time, method and place of conducting any proceedings for any remedy
available to the Trustee or the exercising of any power conferred by this Indenture. 
 (j) Any action taken, or omitted to be
taken, by the Trustee in good faith pursuant to this Indenture upon the request or authority or consent of any person who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and
binding upon future holders of Notes and upon Notes executed and delivered in exchange therefor or in place thereof. 
 (k) The
Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee
at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. 
 (l) The Trustee may
request that the Issuers deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be
signed by any Person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

  
 88 

  
 (m) The Trustee shall
not be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage
and regardless of the form of actions. 
 (n) The Trustee shall not be required to give any bond or surety in respect of the
execution of the trusts and powers under this Indenture. 
 (o) The Trustee shall not be responsible or liable for any failure
or delay in the performance of its obligations under this Indenture arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism;
wars and other military disturbances; sabotage; epidemics; riots; interruptions; loss or malfunction of utilities, computer (hardware or software) or communication services; accidents; labor disputes; and acts of civil or military authorities and
governmental action. 
 SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other
capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights. However, the
Trustee must comply with Sections 7.10 and 7.11. 
 SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not
be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Guarantees or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes, and it shall not be responsible for
any statement of the Issuers or any Guarantor in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication. The Trustee shall not be charged with
knowledge of any Default or Event of Default under Sections 6.01(c), (d), (e), (h), or (i) or of the identity of any Significant Subsidiary unless either (a) a Responsible Officer shall have actual knowledge thereof or (b) the Trustee
shall have received written notice thereof in accordance with Section 13.02 hereof from the Issuers, any Guarantor or any holder. In accepting the trust hereby created, the Trustee acts solely as Trustee for the holders of the Notes and not in
its individual capacity and all persons, including without limitation the holders of Notes and the Issuers having any claim against the Trustee arising from this Indenture shall look only to the funds and accounts held by the Trustee hereunder for
payment except as otherwise provided herein. 
 SECTION 7.05. Notice of Defaults. If a Default occurs and is
continuing and if it is actually known to the Trustee, the Trustee shall mail to each holder notice of the Default within the earlier of 90 days after it occurs or 30 days after it is actually known to a Trust Officer or written notice of it is
received by the Trustee. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines
that withholding the notice is in the interests of the holders. The Issuers are required to deliver to the Trustee, 

  
 89 

 
annually, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. The Issuers also are required to deliver to the Trustee, within 30 days
after the occurrence thereof, written notice of any event which would constitute Defaults, their status and what action the Issuers are taking or propose to take in respect thereof. 

SECTION 7.06. Reports by Trustee to the Holders. As promptly as practicable after each May 15 beginning with the
May 15 following the date of this Indenture, and in any event prior to July 15 in each year, the Trustee shall mail to each holder a brief report dated as of such May 15 that complies with Section 313(a) of the TIA if and to the
extent required thereby. The Trustee shall also comply with Section 313(b) of the TIA. 
 A copy of each report at the time
of its mailing to the holders shall be filed with the SEC and each stock exchange (if any) on which the Notes are listed. The Issuers agree to notify promptly the Trustee whenever the Notes become listed on any stock exchange and of any delisting
thereof. 
 SECTION 7.07. Compensation and Indemnity. The Issuers shall pay to the Trustee from time to time such
compensation, as the Issuers and the Trustee shall from time to time agree in writing, for the Trustee’s acceptance of this Indenture and its services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of
a trustee of an express trust. The Issuers shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses Incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses
shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuers and the Guarantors, jointly and severally, shall indemnify the Trustee or any predecessor
Trustee and their directors, officers, employees and agents against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses and including taxes (other than taxes based upon, measured by or
determined by the income of the Trustee) Incurred by or in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture or Guarantee against
any Issuer or any Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by any Issuer, any Guarantor, any holder or any other Person). The obligation to pay such amounts shall survive
the payment in full or defeasance of the Notes or the removal or resignation of the Trustee. The Trustee shall notify the Issuers of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided,
however, that any failure so to notify the Issuers shall not relieve any Issuer or any Guarantor of its indemnity obligations hereunder. The Issuers shall defend the claim and the indemnified party shall provide reasonable cooperation at the
Issuers’ expense in the defense. Such indemnified parties may have separate counsel and the Issuers and such Guarantor, as applicable shall pay the fees and expenses of such counsel; provided, however, that the Issuers shall not
be required to pay such fees and expenses if they assume such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of interest between the Issuers and the Guarantor, as applicable, and
such parties in connection with such defense. The Issuers need not reimburse any expense or indemnify against any loss, liability or expense Incurred by an indemnified party through such party’s own willful misconduct, negligence or bad faith.

  
 90 

  
 To secure the
Issuers’ and the Guarantors’ payment obligations in this Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and
interest on particular Notes. 
 The Issuers’ and the Guarantors’ payment obligations pursuant to this Section shall
survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee. Without prejudice to any other rights available to the Trustee under
applicable law, when the Trustee Incurs expenses after the occurrence of a Default specified in Section 6.01(f) or (g) with respect to the Issuers, the expenses are intended to constitute expenses of administration under the Bankruptcy
Law. 
 No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise Incur any
financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not assured to its satisfaction. 

SECTION 7.08. Replacement of Trustee. 
 (a) The Trustee may resign at any time by so notifying the Issuers. The holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the Trustee and may appoint a
successor Trustee. The Issuers shall remove the Trustee if: 
 (i) the Trustee fails to comply with
Section 7.10; 
 (ii) the Trustee is adjudged bankrupt or insolvent; 

(iii) a receiver or other public officer takes charge of the Trustee or its property; or 

(iv) the Trustee otherwise becomes incapable of acting.

 92 

 
or any other rights pertaining thereto and the Trustee shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office
at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral
is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding
agency or other agent or bailee selected by the Trustee in good faith.

ARTICLE VIII 
 DISCHARGE OF INDENTURE; DEFEASANCE 
 SECTION 8.01. Discharge of
Liability on Notes; Defeasance. 
 (a) This Indenture shall be discharged and shall cease to be of further effect (except as
to surviving rights of registration of transfer or exchange of Notes, as expressly provided for in this Indenture) as to all outstanding Notes when: 
 (i) either (a) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been
deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from such trust) have been delivered to the Trustee for cancellation or (b) all of the Notes (1) have become due and
payable, (2) will become due and payable at their stated maturity within one year or (3) if redeemable at the option of the Issuers, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the
giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers, and the Issuers have irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire
Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit together with irrevocable instructions from the Issuers directing the Trustee to
apply such funds to the payment thereof at maturity or redemption, as the case may be; 

  
 93 

  
 (ii)
the Issuers and/or the Guarantors have paid all other sums payable under this Indenture; and 
 (iii) the Issuers
have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with. 

(b) Subject to Sections 8.01(c) and 8.02, the Issuers at any time may terminate (i) all of their obligations under the Notes and
this Indenture (with respect to the holders of the Notes) (“legal defeasance option”) or (ii) their obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.11, 4.12, 4.13 and 4.15 and the operation of
Section 5.01 for the benefit of the holders of the Notes, and Sections 6.01(c), 6.01(d) and Sections 6.01(e) and 6.01(f) (in the case of Sections 6.01(e) and 6.01(f) with respect to Significant Subsidiaries of QD LLC only), 6.01(g), 6.01(h),
6.01(i) and 6.01(j) (“covenant defeasance option”). The Issuers may exercise their legal defeasance option notwithstanding their prior exercise of their covenant defeasance option. In the event that the Issuers terminate all of
their obligations under the Notes and this Indenture (with respect to such Notes) by exercising their legal defeasance option or their covenant defeasance option, the obligations of each Guarantor with respect to its Guarantee and the Security
Documents shall be terminated simultaneously with the termination of such obligations. 
 If the Issuers exercises their legal
defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of Default. If the Issuers exercise their covenant defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of
Default specified in Section 6.01(c), 6.01(d), 6.01(e) and 6.01(f) (with respect to Significant Subsidiaries of QD LLC only), 6.01(g), 6.01(h), 6.01(i) or 6.01(j) or because of the failure of the Issuers to comply with Section 5.01.

 Upon satisfaction of the conditions set forth herein and upon request of the Issuers, the Trustee shall acknowledge in
writing the discharge of those obligations that the Issuers terminate. 
 (c) Notwithstanding clauses (a) and
(b) above, the Issuers’ obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, Article VII, including, without limitation, Sections 7.07 and 7.08 and in this Article VIII shall survive until the Notes have been paid in full.
Thereafter, the Issuers’ obligations in Sections 7.07, 8.05 and 8.06 shall survive such satisfaction and discharge. 

SECTION 8.02. Conditions to Defeasance. 
 (a) The Issuers may exercise their legal defeasance option or their covenant defeasance option only if: 
 (i) the Issuers irrevocably deposit in trust with the Trustee cash in U.S. Dollars, U.S. Government Obligations or a combination thereof in an amount sufficient or U.S. Government Obligations, the
principal of and the interest on which will be sufficient, or a combination thereof sufficient, to pay the principal of and premium (if any) and interest on the Notes when due at maturity or redemption, as the case may be, including interest thereon
to maturity or such redemption date; 

  
 94 

  
 (ii)
the Issuers deliver to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government
Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if any, and interest when due on all the Notes to maturity or redemption, as the case
may be; 
 (iii) 123 days pass after the deposit is made and during the 123-day period no Default specified in
Section 6.01(e) or (f) with respect to the Issuers occurs which is continuing at the end of the period; 
 (iv) the deposit does not constitute a default under any other agreement binding on the Issuers and is not prohibited by Article X; 

(v) in the case of the legal defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel
stating that (1) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling, or (2) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either
case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred. Notwithstanding the foregoing, the Opinion of Counsel required by the immediately preceding
sentence with respect to a legal defeasance need not be delivered if all of the Notes not theretofore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due and payable at their Stated Maturity
within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers; 

(vi) such exercise does not impair the right of any holder to receive payment of principal of, premium, if any, and
interest on such holder’s Notes on or after the due dates therefore or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes; 

(vii) in the case of the covenant defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel
to the effect that the holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such deposit and defeasance had not occurred; and 
 (viii) the Issuers deliver to
the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes to be so defeased and discharged as contemplated by this Article VIII have been complied
with. 

  
 95 

  
 (b) Before or after a
deposit, the Issuers may make arrangements satisfactory to the Trustee for the redemption of such Notes at a future date in accordance with Article III. 
 SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations (including proceeds thereof) deposited with it pursuant to this Article VIII. It
shall apply the deposited money and the money from U.S. Government Obligations through each Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Notes so discharged or defeased. 

SECTION 8.04. Repayment to Issuers. Each of the Trustee and each Paying Agent shall promptly turn over to the Issuers upon
request any money or U.S. Government Obligations held by it as provided in this Article which, in the written opinion of nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall only be required if
U.S. Government Obligations have been so deposited), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article. 

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Issuers upon written request any
money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, holders entitled to the money must look to the Issuers for payment as general creditors, and the Trustee and each Paying Agent shall
have no further liability with respect to such monies. 
 SECTION 8.05. Indemnity for U.S. Government Obligations.
The Issuers shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. 

SECTION 8.06. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or U.S. Government Obligations
in accordance with this Article VIII by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ obligations under
this Indenture and the Notes so discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or any Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with this Article VIII; provided, however, that, if the Issuers have made any payment of principal of, or interest on, any such Notes because of the reinstatement of its obligations, the Issuers
shall be subrogated to the rights of the holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or any Paying Agent.

SECTION 9.02. With Consent of the Holders. 
 (a) The Issuers and the Trustee may amend this Indenture and the Security Documents with the written consent of the holders of at least a majority in principal amount of the Notes then outstanding voting

amendment, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment under this
Section 9.02 becomes effective, the Issuers shall mail to the holders a notice briefly describing such amendment. The failure to give such notice to all holders, or any defect therein, shall not impair or affect the validity of an amendment

permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were holders at such record date (or their duly designated proxies), and only those Persons,
shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be holders after such record date. No such consent shall be valid or effective for more than 120

regarding the changed terms and return it to the holder. Alternatively, if the Issuers or the Trustee so determine, the Issuers in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms.
Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment, supplement or waiver.

replaced from time to time in accordance with its terms or the terms of this Indenture, authorizes and directs the Trustee and the Collateral Agent to enter into the Security Documents to which it is a party, authorizes and empowers the Trustee to
direct the Collateral Agent to enter into, and the Collateral Agent to execute and deliver, the Intercreditor Agreement and authorizes and empowers the Trustee and the Collateral Agent to bind the holders of Notes and other holders of Obligations as
set forth in the Security Documents to which it is a party and the Intercreditor Agreement and to perform its obligations and exercise its rights and powers thereunder. 

(b) The Collateral Agent and the Trustee are authorized and empowered to receive for the benefit of the holders of Notes
any funds collected or distributed under the Security Documents to which the Collateral Agent or Trustee is a party and to make further distributions of such funds to the holders of Notes according to the provisions of this Indenture. 

(c) Subject to the provisions of Section 7.01 and Section 7.02 hereof, the Intercreditor Agreement and the
Security Documents, the Trustee may, in its sole discretion and without the consent of the holders, direct, on behalf of the holders, the Collateral Agent to take all actions it deems necessary or appropriate in order to: 

(1) foreclose upon or otherwise enforce any or all of the Second Priority Liens; 

  
 103

  
 (2)
enforce any of the terms of the Security Documents to which the Collateral Agent or Trustee is a party; or 
 (3)

 Subject to the Intercreditor Agreement, the Trustee is authorized and
empowered to institute and maintain, or direct the Collateral Agent to institute and maintain, such suits and proceedings as it may deem expedient to protect or enforce the Second Priority Liens or the Security Documents to which the Collateral
Agent or Trustee is a party or to prevent any impairment of Collateral by any acts that may be unlawful or in violation of the Security Documents to which the Collateral Agent or Trustee is a party or this Indenture, and such suits and proceedings
as the Trustee or the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the holders of Notes in the Collateral, including power to institute and maintain suits or proceedings to restrain the enforcement of
or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder
or be prejudicial to the interests of holders, the Trustee or the Collateral Agent. 
 SECTION 11.04. Release of
Liens. (a) Notwithstanding anything to the contrary in the Collateral Agreement and subject to subsections (b) and (c) of this Section 11.04, Collateral may be released from the Lien and security interest created by the
Security Documents to secure the Notes and obligations under this Indenture at any time or from time to time in accordance with the provisions of the Intercreditor Agreement or as provided hereby. The applicable assets included in the Collateral
shall be automatically released from the Liens securing the Notes, and the applicable Guarantor shall be automatically released from its obligations under this Indenture and the Security Documents, under any one or more of the following
circumstances or any applicable circumstance as provided in the Intercreditor Agreement or the Security Documents: 
 (1) upon
the Discharge of Senior Lender Claims and concurrent release of all other Liens on such property or assets securing First Priority Lien Obligations (including all commitments and letters of credit thereunder); provided, however, that
if the Issuers or the Guarantors subsequently incur First Priority Lien Obligations that are secured by Liens on property or assets of the Issuers or the Guarantors of the type constituting the Collateral and the related Liens are incurred in
reliance on clause (6)(B) of the definition of Permitted Liens, then the Issuers and the Restricted Subsidiaries will be required to reinstitute the security arrangements with respect to the Collateral in favor of the Notes, which, in the case
of any such subsequent First Priority Lien Obligations, will be Second Priority Liens on the Collateral securing such First Priority Lien Obligations to the same extent provided by the Security Documents and on the terms and conditions of the
security documents relating to such First Priority Lien Obligations, with the Second Priority Lien held either by the administrative agent, collateral agent or other representative for such First Priority Lien Obligations or by a collateral agent or
other representative designated by the Issuers to hold the Second Priority Liens for the 

  
 104

 
benefit of the holders of the Notes and subject to an intercreditor agreement that provides the administrative agent or collateral agent substantially the same rights and powers as afforded under
the Intercreditor Agreement; provided, however, that the Issuers will provide the Trustee and Collateral Agent under the Collateral Agreement with prompt written notification of such reinstitution; 

(2) [Intentionally omitted]; 
 (3) [Intentionally omitted]; 
 (4) [Intentionally omitted]; 

(5) to enable the Issuers or any Guarantor to consummate the disposition (other than any disposition to an Issuer or another Guarantor)
of such property or assets to the extent not prohibited under Section 4.06, and to enable any release described in Section 9.15(c) of the Collateral Agreement; 
 (6) in respect of the property and assets of a Guarantor, upon the designation of such Guarantor to be an Unrestricted Subsidiary in accordance with Section 4.04 and the definition of
“Unrestricted Subsidiary”, and such Guarantor shall be automatically released from its obligations hereunder and under the Security Documents; 
 (7) in respect of the property and assets of a Guarantor, upon the release or discharge of the pledge granted by such Guarantor to secure the Obligations under the Credit Agreement or any other
Indebtedness or the guarantee of any other Indebtedness which resulted in the obligation to become a Guarantor; and 
 (8) as
described under Article IX. 
 Notwithstanding the foregoing, if an Event of Default under this Indenture exists on the date of
Discharge of Senior Lender Claims, the Second Priority Liens on the Collateral securing the Notes will not be released, except to the extent the Collateral or any portion thereof was disposed of in order to repay the First Priority Lien Obligations
secured by the Collateral, and thereafter the Trustee (or another designated representative acting at the direction of the holders of a majority of outstanding principal amount of the Notes and Other Second-Lien Obligations) will have the right to
direct the First Lien Agent to foreclose upon the Collateral (but in such event, the Liens on the Collateral securing the Notes will be released when such Event of Default and all other Events of Default under this Indenture cease to exist).

 In connection with any termination or release pursuant to this Section 11.04(a), the Collateral Agent shall execute and
deliver to any Pledgor (as defined in the Collateral Agreement), at such Pledgor’s expense, all documents that such Pledgor shall reasonably request to evidence such termination or release (including, without limitation, UCC termination
statements), and will duly assign and transfer to such Pledgor, such of the Pledged Collateral (as defined in the Collateral Agreement) that may be in the possession of the Collateral Agent and has not theretofore been sold or otherwise applied or
released pursuant to this Indenture or the Security Documents. Any execution and delivery of documents pursuant to this Section 11.04(a) shall be without recourse to or warranty by the Collateral Agent. In connection with any release

  
 105

 
pursuant to this Section 11.04(a), the Pledgors shall be permitted to take any action in connection therewith consistent with such release including, without limitation, the filing of UCC
termination statements. 
 Upon the receipt of an Officer’s Certificate from QD LLC, as described in Section 11.04(b)
below, if applicable, and any necessary or proper instruments of termination, satisfaction or release prepared by the Issuers, the Collateral Agent shall execute, deliver or acknowledge such instruments or releases to evidence the release of any
Collateral permitted to be released pursuant to this Indenture or the Security Documents or the Intercreditor Agreement. 
 (b) Notwithstanding anything herein to the contrary, in connection with (x) any release of Collateral pursuant to Section 11.04(a)(1), (6), (7) or (8) above, such Collateral may not be
released from the Lien and security interest created by the Security Documents and (y) any release of Collateral pursuant to Section 11.04(a)(2), (3), (4) and (5), the Collateral Agent shall not be required to execute, deliver or
acknowledge any instruments of termination, satisfaction or release unless, in each case, an Officer’s Certificate and Opinion of Counsel certifying that all conditions precedent, including, without limitation, this Section 11.04, have
been met and stating under which of the circumstances set forth in Section 11.04(a) above the Collateral is being released have been delivered to the Collateral Agent on or prior to the date of such release or, in the case of clause
(y) above, the date on which the Collateral Agent executes any such instrument. 
 (c) Notwithstanding
anything herein to the contrary, at any time when a Default or Event of Default has occurred and is continuing and the maturity of the Notes has been accelerated (whether by declaration or otherwise) and the Trustee has delivered a notice of
acceleration to the Collateral Agent, no release of Collateral pursuant to the provisions of this Indenture or the Security Documents will be effective as against the holders, except as otherwise provided in the Intercreditor Agreement. 

SECTION 11.05. Filing, Recording and Opinions. (a) The Issuers will comply with the provisions of TIA Sections 314(b),
314(c) and 314(d), in each case following qualification of this Indenture pursuant to the TIA and except to the extent not required as set forth in any SEC regulation or interpretation (including any no-action letter issued by the Staff of the SEC,
whether issued to the Issuers or any other Person). Following such qualification, to the extent the Issuers are required to furnish to the Trustee an Opinion of Counsel pursuant to TIA Section 314(b)(2), the Issuers will furnish such opinion
not more than 60 but not less than 30 days prior to each September 30. 
 Any release of Collateral permitted by
Section 11.04 hereof will be deemed not to impair the Liens under this Indenture and the Security Documents in contravention thereof and any person that is required to deliver an Officer’s Certificate or Opinion of Counsel pursuant to
Section 314(d) of the TIA, shall be entitled to rely upon the foregoing as a basis for delivery of such certificate or opinion. The Trustee may, to the extent permitted by Section 7.01 and 7.02 hereof, accept as conclusive evidence of
compliance with the foregoing provisions the appropriate statements contained in such documents and Opinion of Counsel. 

  
 106

  
 (b) If
any Collateral is released in accordance with this Indenture and if the Issuers have delivered the certificates and documents required by the Security Documents and Section 11.04, the Trustee will determine whether it has received all
documentation required by TIA Section 314(d) in connection with such release and, based on such determination and the Opinion of Counsel delivered pursuant to Section 11.04, will, upon request, deliver a certificate to the Collateral Agent
setting forth such determination. 
 SECTION 11.06. [Intentionally omitted]. 

SECTION 11.07. Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in the possession of a receiver or
trustee, lawfully appointed, the powers conferred in this Article XI upon the Issuers or the Guarantors with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by
such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuers or the Guarantors or of any officer or officers thereof required by the provisions of this Article XI; and if the Trustee shall be in the possession of
the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee. 
 SECTION 11.08.
Release Upon Termination of the Issuers’ Obligations. In the event (i) that QD LLC delivers to the Trustee, in form and substance acceptable to it, an Officer’s Certificate and Opinion of Counsel certifying that all the
obligations under this Indenture, the Notes and the Security Documents have been satisfied and discharged by the payment in full of the Issuers’ obligations under the Notes, this Indenture and the Security Documents, and all such obligations
have been so satisfied, or (ii) a discharge, legal defeasance or covenant defeasance of this Indenture occurs under Article VIII, the Trustee shall deliver to QD LLC and the Collateral Agent a notice stating that the Trustee, on behalf of the
holders, disclaims and gives up any and all rights it has in or to the Collateral, and any rights it has under the Security Documents, and upon receipt by the Collateral Agent of such notice, the Collateral Agent shall be deemed not to hold a Lien
in the Collateral on behalf of the Trustee and shall do or cause to be done all acts reasonably necessary at the request of the Issuers to release such Lien as soon as is reasonably practicable. 

SECTION 11.09. Designations. Except as provided in the next sentence, for purposes of the provisions hereof and the
Intercreditor Agreement requiring the Issuers to designate Indebtedness for the purposes of the terms First Priority Lien Obligations and Other Second-Lien Obligations or any other such designations hereunder or under the Intercreditor Agreement,
any such designation shall be sufficient if the relevant designation provides in writing that such First Priority Lien Obligations or Other Second-Lien Obligations are permitted under this Indenture and is signed on behalf of the Issuers by an
Officer and delivered to the Trustee, the Collateral Agent and the First Lien Agent. For all purposes hereof and the Intercreditor Agreement, the Issuers hereby designate the Obligations pursuant to the Credit Agreement as in effect on the Issue
Date as First Priority Lien Obligations. 
 SECTION 11.10. Taking and Destruction. Following the Discharge of Senior
Lender Claims, upon any Taking or Destruction of any Collateral, all Net Insurance Proceeds received by the Issuers or any Restricted Subsidiary shall be deemed Net Proceeds and shall be applied in accordance with Section 4.06.

 ARTICLE XII

 GUARANTEE 
 SECTION 12.01. Guarantee. 
 (a) Each Guarantor hereby jointly and
severably, irrevocably and unconditionally guarantees, on a second-priority secured basis, as a primary obligor and not merely as a surety, to each holder and to the Trustee and its successors and assigns (i) the full and punctual payment when
due, whether at Stated Maturity, by acceleration, by redemption or otherwise, of all obligations of the Issuers under this Indenture (including obligations to the Trustee) and the Notes, whether for payment of principal of, premium, if any, or
interest on in respect of the Notes and all other monetary obligations of the Issuers under this Indenture and the Notes and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuers whether
for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice or further assent from any Guarantor, and that each Guarantor shall remain bound under this Article XII notwithstanding any extension or renewal of any Guaranteed
Obligation. 
 (b) Each Guarantor waives presentation to, demand of payment from and protest to the Issuers of any of the
Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the
failure of any holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Issuers or any other Person under this Indenture, the Notes or any other agreement or otherwise; (ii) any extension or renewal of
this Indenture, the Notes or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (iv) the release of any security held by any
holder or the Trustee for the Guaranteed Obligations or each Guarantor; (v) the failure of any holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership
of each Guarantor, except as provided in Section 12.02(b) or Section 12.02(c). Each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Guarantors, such that such
Guarantor’s obligations would be less than the full amount claimed. 
 (c) Each Guarantor hereby waives any right to which
it may be entitled to have the assets of the Issuers first be used and depleted as payment of the Issuers’ or such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder. Each
Guarantor hereby waives any right to which it may be entitled to require that the Issuers be sued prior to an action being initiated against such Guarantor. 
 (d) Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that
any resort be had by any holder or the Trustee to any security held for payment of the Guaranteed Obligations. 

  
 108

  
 (e) The Guarantee of
each Guarantor is, to the extent and in the manner set forth in Article XII, equal in right of payment to all existing and future Pari Passu Indebtedness, senior in right of payment to all existing and future Subordinated Indebtedness of the Issuers
and subordinated and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Secured Indebtedness of the relevant Guarantor and is made subject to such provisions of this Indenture.

 (f) Except as expressly set forth in Sections 8.01(b), 12.02 and 12.06, the obligations of each Guarantor hereunder shall not
be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or
termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or
impaired or otherwise affected by the failure of any holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default,
failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would
otherwise operate as a discharge of any Guarantor as a matter of law or equity. 
 (g) Each Guarantor agrees that its Guarantee
shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any holder or the Trustee upon the bankruptcy or reorganization of the Issuers or otherwise. 

(h) In furtherance of the foregoing and not in limitation of any other right which any holder or the Trustee has at law or in equity
against any Guarantor by virtue hereof, upon the failure of the Issuers to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the holders or the Trustee an amount equal to the sum
of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of
the Issuers to the holders and the Trustee. 
 (i) Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the holders and the
Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee herein, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article VI, such Guaranteed Obligations (whether or
not due and payable) shall forthwith become due and payable by the Guarantors for the purposes of this Section 12.01. 

  
 109

  
 (j) Each Guarantor
also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) Incurred by the Trustee or any holder in enforcing any rights under this Section 12.01. 

(k) Upon request of the Trustee, each Guarantor shall execute and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 
 SECTION 12.02. Limitation
on Liability. 
 (a) Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount
of the Guaranteed Obligations guaranteed hereunder by each Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 
 (b) A Guarantee as
to any Subsidiary that is a party hereto on the date hereof or that executes a supplemental indenture in accordance with Section 4.11 hereof and provides a guarantee shall terminate and be of no further force or effect and such Guarantor shall
be deemed to be released from all obligations under this Article XII upon: 
 (i) the sale, disposition, exchange
or other transfer (including through merger, consolidation, amalgamation or otherwise) of the Capital Stock (including any sale, disposition or other transfer following which the applicable Guarantor is no longer a Wholly-Owned Restricted
Subsidiary), of the applicable Guarantor if such sale, disposition, exchange or other transfer is made in a manner not in violation of this Indenture; 
 (ii) QD LLC designating such Guarantor to be an Unrestricted Subsidiary in accordance with the provisions of Section 4.04 and the definition of “Unrestricted Subsidiary”; 

(iii) the release or discharge of the guarantee of any other Indebtedness which resulted in the obligation to guarantee
the Notes; and 
 (iv) the Issuers’ exercise of their legal defeasance option or covenant defeasance option
under Article VIII or if the Issuers’ obligations under this Indenture are discharged in accordance with the terms of this Indenture. 
 A Guarantee as to any Subsidiary also will be automatically released upon the applicable Subsidiary ceasing to be a Subsidiary as a result of any foreclosure of any pledge or security interest securing
Bank Indebtedness or other exercise of remedies in respect thereof. 

  
 110

  
 (c) QDI’s
Guarantee shall terminate and be of no further force or effect and QDI shall be deemed to be released from all obligations under this Article XII upon: 
 (i) QD LLC ceasing to be a Wholly-Owned Subsidiary of QDI; 
 (ii)
QD LLC’s transfer of all or substantially all of its assets to, or merger with, an entity that is not a Wholly-Owned Subsidiary of QDI in accordance with Section 5.01 and such transferee entity assumes QD LLC’s obligations under this
Indenture; and 
 (iii) the Issuers’ exercise of its legal defeasance option or covenant defeasance option
under Article VIII or if the Issuers’ obligations under this Indenture are discharged in accordance with the terms of this Indenture. 
 SECTION 12.03. Successors and Assigns. This Article XII shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the
Trustee and the holders and, in the event of any transfer or assignment of rights by any holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions of this Indenture. 
 SECTION 12.04. No Waiver.
Neither a failure nor a delay on the part of either the Trustee or the holders in exercising any right, power or privilege under this Article XII shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or
further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under
this Article XII at law, in equity, by statute or otherwise. 
 SECTION 12.05. Modification. No modification,
amendment or waiver of any provision of this Article XII, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle any Guarantor to any other or further notice or demand in the same, similar or other
circumstances. 
 SECTION 12.06. Execution of Supplemental Indenture for Future Guarantors. Each which is required
to become a Guarantor of the Notes pursuant to Section 4.11 shall promptly execute and deliver to the Trustee a joinder to the Intercreditor Agreement and a supplemental indenture in the form of Exhibit D hereto pursuant to which such Person
shall become a Guarantor under this Article XII and shall guarantee the Notes. Concurrently with the execution and delivery of such supplemental indenture, the Issuer shall deliver to the Trustee an Opinion of Counsel and an Officer’s
Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other
similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a valid and binding obligation of such Guarantor, enforceable
against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request. 

  
 111

Non-Impairment. The failure to endorse a Guarantee on any Note shall not affect or impair the validity thereof.

transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such holder elects payment by wire transfer by giving written notice to the Trustee or Paying Agent to such effect designating such account no later than

any declaration or other act on the part of the Trustee or any holders. Under certain circumstances, the holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its
consequences. 

  
 A-11

  
 If an Event of Default
occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders unless such holders have offered to the Trustee indemnity or security
satisfactory to the Trustee against any loss, liability or expense and certain other conditions are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder may pursue any remedy
with respect to the Indenture or the Notes unless (i) such holder has previously given the Trustee notice that an Event of Default is continuing, (ii) the holders of at least 30% in principal amount of the outstanding Notes have requested
the Trustee in writing to pursue the remedy, (iii) such holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense, (iv) the Trustee has not complied with such request within 60 days after the
receipt of the request and the offer of security or indemnity and (v) the holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.
Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising
any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder or that would
involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such
action. 
 16. Trustee Dealings with the Issuer 
 Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and
collect obligations owed to it by the Issuers or their Affiliates and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee. 
 17. No Recourse Against Others 
 No director, officer, employee,
incorporator or holder of any equity interests in an Issuer or of any Guarantor or any direct or indirect parent corporation, as such, shall have any liability for any obligations of an Issuer or any Guarantor under the Notes, the Indenture or for
any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of Notes by accepting a Note waives and releases all such liability.

OF EXCHANGE NOTE] 
 9.875% Second-Priority Senior Secured Note Due 2018 

1. Interest 
 QUALITY
DISTRIBUTION LLC, a Delaware limited liability company and QD CAPITAL CORPORATION, a Delaware corporation (such entities, and their successors and assigns under the Indenture hereinafter referred to, being herein called the
“Issuers”), promise to pay interest on the principal amount of this Note at the rate per annum shown above. The Issuers shall pay interest semiannually on May 1 and November 1 of each year (each an “Interest
Payment Date”), commencing May 1, 2011. Interest on the Notes shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from November 3,
2010, until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Issuers shall pay interest on overdue principal at the rate borne by the Notes, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful. 
 2. Method of Payment 

The Issuers shall pay interest on the Notes (except defaulted interest) to the Persons who are registered holders at the close of business
on April 15 or October 15 (each a “Record Date”) next preceding the Interest Payment Date even if Notes are canceled after the Record Date and on or before the Interest Payment Date (whether or not a Business Day). Holders
must surrender Notes to the Paying Agent to collect principal payments. The Issuers shall pay principal, premium, if any, and interest in money of the United States of America that at the time of payment is legal tender for payment of public and
private debts. Payments in respect of the Notes represented by a Global Note (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company
or any successor depositary. The Issuers shall make all payments in respect of a certificated Note (including principal, premium, if any, and interest) at the office of the Paying Agent, except that, at the option of the Issuers, payment of interest
may be made by mailing a check to the registered address of each holder thereof; provided, however, that payments on the Notes may also be made, in the case of a holder of at least $1,000,000 aggregate principal amount of Notes, by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such holder elects payment by wire transfer by giving written notice to the Trustee or Paying Agent to such effect designating such account no later than
30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
 3.
Paying Agent and Registrar 
 Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”),
will act as Paying Agent and Registrar. The Issuers may appoint and change any Paying Agent or Registrar without notice. The QD LLC or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent or Registrar. 

  
 B-5

  
 4. Indenture 

The Issuers issued the Notes under an Indenture dated as of November 3, 2010 (the “Indenture”), among the Issuers,
the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa 77bbbb) as in effect on the date of the
Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all terms and provisions of the Indenture, and the holders (as defined in the
Indenture) are referred to the Indenture and the TIA for a statement of such terms and provisions. 
 The Notes are
second-priority senior secured obligations of the Issuers. This Note is one of the Initial Notes referred to in the Indenture. The Notes include the Initial Notes, any Additional Notes and any Exchange Notes issued in exchange for the Initial Notes
or any Additional Notes pursuant to the Indenture. The Initial Notes, any Additional Notes and any Exchange Notes are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the ability of the
Issuers and the Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions, Incur Indebtedness, enter into consensual restrictions upon the payment of certain
dividends and distributions by the Restricted Subsidiaries, issue or sell shares of capital stock of the Issuers and the Restricted Subsidiaries, enter into or permit certain transactions with Affiliates, create or Incur Liens and make Asset Sales.
The Indenture also imposes limitations on the ability of each Issuer and each Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of its property.

the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors have unconditionally guaranteed the Guaranteed
Obligations pursuant to the terms of the Indenture and any Guarantor that executes a Guarantee will unconditionally guarantee the Guaranteed Obligations on a second-priority senior secured basis pursuant to the terms of the Indenture.

interest and additional interest, if any, to the redemption date (subject to the right of holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the 12-month period commencing

Notwithstanding the foregoing, at any time and from time to time on or prior to November 1, 2013, the Issuers may redeem in the
aggregate up to 35% of the original aggregate principal amount of the Notes (calculated after giving effect to any issuance of Additional Notes) with the net cash proceeds of one or more Equity Offerings (1) by QD LLC or (2) by any direct

percentage of principal amount thereof) of 109.875%, plus accrued and unpaid interest and Additional Interest, if any, to the redemption date (subject to the right of holders of record on the relevant Record Date to receive interest due on
the relevant Interest Payment Date); provided, however, that at least 50% of the original aggregate principal amount of the Notes (calculated after giving effect to any issuance of Additional Notes) must remain outstanding after each such
redemption; provided, further, that such redemption shall occur within 90 days after the date on which any such Equity Offering is consummated upon not less than 30 nor more than 60 days’ notice mailed to each holder of Notes being
redeemed and otherwise in accordance with the procedures set forth in the Indenture. 
 6. Mandatory Redemption 

Except as set forth in the Indenture, the Issuers shall not be required to make mandatory redemption or sinking fund payments with respect
to the Notes. 
 7. Notice of Redemption 
 Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed at his, her or its registered address.

 B-7

  
 8. Repurchase of Notes at the
Option of the Holders upon Change of Control and Asset Sales 
 Upon the occurrence of a Change of Control, each holder shall
have the right, subject to certain conditions specified in the Indenture, to cause the Issuers to repurchase all or any part of such holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued
and unpaid interest, if any, to the date of repurchase (subject to the right of the holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), as provided in, and subject to the terms of, the
Indenture. 
 In accordance with Section 4.06 of the Indenture, the Issuers will be required to offer to purchase Notes
upon the occurrence of certain events. 
 9. Ranking and Collateral 

These Notes and the Guarantees will be secured by a second-priority security interest in the Collateral pursuant to certain Security
Documents. The Second Priority Liens upon any and all Collateral are, to the extent and in the manner provided in the Intercreditor Agreement, subordinate in ranking to all present and future First Priority Liens and will be of equal ranking with
all present and future Liens securing Other Second-Lien Obligations as set forth in the Intercreditor Agreement.

Transfer; Exchange 
 The Notes are in registered form, without coupons, in denominations of $2,000 and integral multiples of

Agent shall have no further liability with respect to such monies. 

  
 B-8

  
 13. Discharge and Defeasance

 Subject to certain conditions, the Issuers at any time may terminate some of or all its obligations under the Notes and the

Indenture, (i) the Indenture or the Notes may be amended with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding Notes and (ii) any past default or compliance with any provisions may

conform the text of the Indenture, the Notes, the Security Documents or the Intercreditor Agreement to any provision of the “Description of Notes” in the Offering Memorandum to the extent that such provision in the
“Description of Notes” was intended to be a verbatim recitation of a provision of the Indenture, the Notes, the Security Documents or the Intercreditor Agreement; (vii) to add Collateral to secure the Notes; (viii) to add
additional covenants of the Issuers for the benefit of the holders or to surrender rights and powers conferred on the Issuers; (ix) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture
under the TIA; (x) to make any change that does not adversely affect the rights of any holder; (xi) to provide for the issuance of the Exchange Notes or Additional Notes; (xii) to release Collateral as permitted by the Indenture or
the Intercreditor Agreement; or (xiii) to add additional secured creditors holding Other Second-Lien Obligations so long as such obligations are not prohibited by the Indenture or the Security Documents. 

15. Defaults and Remedies 

If an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of QD
LLC) and is continuing, the Trustee or the holders of at least 25% in principal amount of the outstanding Notes, in each case, by notice to the Issuers, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes
to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of QD LLC occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and payable without
any declaration or other act on the part of the Trustee or any holders. Under certain circumstances, the holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its
consequences. 

  
 B-9

  
 If an Event of Default
occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders unless such holders have offered to the Trustee indemnity or security
satisfactory to the Trustee against any loss, liability or expense and certain other conditions are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder may pursue any remedy
with respect to the Indenture or the Notes unless (i) such holder has previously given the Trustee notice that an Event of Default is continuing, (ii) the holders of at least 30% in principal amount of the outstanding Notes have requested
the Trustee in writing to pursue the remedy, (iii) such holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense, (iv) the Trustee has not complied with such request within 60 days after the
receipt of the request and the offer of security or indemnity and (v) the holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.
Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising
any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder or that would
involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such
action. 
 16. Trustee Dealings with the Issuer 
 Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and
collect obligations owed to it by the Issuers or their Affiliates and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee. 
 17. No Recourse Against Others 
 No director, officer, employee,
incorporator or holder of any equity interests in an Issuer or of any Guarantor or any direct or indirect parent corporation, as such, shall have any liability for any obligations of an Issuer or any Guarantor under the Notes, the Indenture or for
any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of Notes by accepting a Note waives and releases all such liability.

TRANSFEREE LETTER OF REPRESENTATION 
 [Quality Distribution, LLC] 
 [QD Capital Corporation] 

c/o The Bank of New York Mellon Trust Company, N.A. 
 [    ] 
 Ladies and Gentlemen: 

This certificate is delivered to request a transfer of $[            ]
principal amount of the 9.875% Second-Priority Senior Secured Notes due 2018 (the “Notes”) of Quality Distribution, LLC and QD Capital Corporation (together, the “Issuers”). 

Upon transfer, the Notes would be registered in the name of the new beneficial owner as follows: 

 

							
	Name:	  	  
	  		  	
				
	Address:	  	  
	  		  	

 Taxpayer ID Number:
                                         
                        
 The undersigned represents and warrants to you that: 
 1. We are an institutional
“accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an
institutional “accredited investor” at least $100,000 principal amount of the Notes, and we are acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We
have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Notes, and we invest in or purchase securities similar to the Notes in the normal course of our
business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment. 
 2.
We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we
are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is two years after the later of the date of original issue and the last date on which either of the Issuers or any affiliate of such Issuer was the owner of
such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) in the United States to a person whom we reasonably believe is a qualified institutional buyer (as defined in rule 144A under the
Securities Act) in a transaction meeting the requirements of Rule 144A, (b) outside the United States in an offshore transaction in accordance with Rule 904 of Regulation S under the Securities Act, (c) pursuant to

  
 C-1

 
an exemption from registration under the Securities Act provided by Rule 144 thereunder (if applicable) or (d) pursuant to an effective registration statement under the Securities Act, in
each of cases (a) through (d) in accordance with any applicable securities laws of any state of the United States. In addition, we will, and each subsequent holder is required to, notify any purchaser of the Note evidenced hereby of the
resale restrictions set forth above. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made to an institutional
“accredited investor” prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Issuers and the Trustee, which shall provide, among
other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Notes for investment purposes and not
for distribution in violation of the Securities Act. Each purchaser acknowledges that the Issuers and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Notes pursuant to
clause 1(b), 1(c) or 1(d) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Issuers and the Trustee.
