 Exhibit 10.2 

[NON-EMPLOYEE DIRECTOR GRANT] 
 RESTRICTED STOCK UNIT AGREEMENT 
 UNDER THE 

LORAL SPACE & COMMUNICATIONS INC. 
 2005 STOCK INCENTIVE PLAN 
 THIS AGREEMENT (the “Agreement”) is
made as of the 22nd day of May, 2012 (the “Grant Date”), by and between LORAL SPACE & COMMUNICATIONS INC. (the “Company”) and             (the
“Grantee”). 
 W I T N E S S E T H : 
 WHEREAS, the Grantee is currently a non-employee member of the Board of Directors (the “Board”) of the Company and the Company desires to have him remain in such capacity and grant to him a
notional interest in shares of the Company’s common stock, par value $0.01 per share (the “Stock”), in the form of restricted stock units, subject to certain restrictions and on the terms and conditions set forth herein so that he may
have a direct proprietary interest in the Company’s success. 
 NOW, THEREFORE, in consideration of the covenants and
agreements herein contained, the parties hereto hereby agree as follows: 
 1. Grant of Restricted Stock Units. Subject
to the restrictions, terms and conditions set forth herein and in the Company’s 2005 Stock Incentive Plan, as amended from time to time (the “Plan”), the Company hereby grants to the Grantee
            restricted stock units (the restricted stock units granted hereunder are hereafter referred to as the “Restricted Stock Units”). Each Restricted Stock Unit
shall represent the right to receive upon settlement (i) one share of the Stock or (ii) cash equal to the fair market value of one share of Stock on the settlement date, subject to the terms and conditions set forth herein. The
determination as to whether the Restricted Stock Units are settled in Stock or cash shall be at the sole discretion of the Company. Capitalized terms not defined herein shall have the meaning ascribed to them in the Plan. 

2. Satisfaction of Vesting Conditions. 
 (a) General. Except as provided in this Agreement, the Restricted Stock Units are subject to a substantial risk of forfeiture until vested as set forth in Section 2(b) and are not
transferable. 
 (b) Vesting Schedule. The Restricted Stock Units shall vest as follows. Subject to earlier
forfeiture as provided below, all of the Restricted Stock Units granted hereunder shall vest on the earlier of (i) the first anniversary of the Grant Date (or, if earlier, the date of the Company’s first regular annual meeting of
stockholders held after the Grant Date); or (ii) the termination of the Grantee’s service as a director of the Company by reason of death or permanent disability (each such date, a “Vesting Date”), provided the Grantee has
remained a member of the Board from the date hereof through the Vesting Date. If the Grantee’s membership on the Board is terminated for any reason prior the Vesting Date, the unvested portion of the Restricted Stock Units shall be forfeited by
the Grantee without consideration. 

 3. Settlement of Restricted Stock Units. 

(a) All outstanding vested Restricted Stock Units shall be settled on the earlier of (a) the date of the Grantee’s death,
(b) the date the Grantee undergoes a Separation from Service (as defined below), and (c) the date of consummation of a 409A Change in Control (as defined below), (the first of (a), (b), and (c) to occur shall be the “Settlement
Date”); provided, however, that to the extent that the Grantee is a “specified employee” within the meaning of Treasury Regulation 1.409A-1(i) any settlement of the Restricted Stock Units on account of the Grantee’s
Separation from Service from the Company shall be delayed for such period of time as may be necessary to meet the requirements of Treasury Regulation Section 1.409A-3(i)(2) (the “Delay Period”) and on the first business day following
the expiration of the Delay Period, all vested Restricted Stock Units shall be settled. On the Settlement Date, the Company shall deliver to the Grantee (or the Grantee’s estate in the event of Grantee’s death) (x) a certificate or
certificates representing the number of shares of Stock equal to the number of vested Restricted Stock Units or (y) a lump sum payment of cash having a value equal to the fair market value of one share of Stock as of the Settlement Date
multiplied by the number of vested Restricted Stock Units. The determination as to whether the Restricted Stock Units will be settled in Stock or cash shall be within the sole discretion of the Company. 

(b) For purposes of this Agreement, a “Separation from Service” will be deemed to occur on the date as of which the Grantee has
undergone a “separation from service” (as that term is specifically defined in Treas. Reg. §1.409A-1(h), applying the rules set forth therein) with the Loral Controlled Group (as defined below); provided, however, that
to the extent that the Grantee becomes employed with Loral or any member of the Loral Controlled Group the Grantee will be deemed to undergo a termination of employment on the date that such Grantee’s level of bona fide services performed
decreases to a level less than 50 percent of the average level of services performed by the Grantee during the immediately preceding 36-month period. For purposes of this Agreement the Loral Controlled Group means Loral and all persons and entities
with respect to which Loral would be considered a single employer under Code §414(b) and (c), provided, however, that in applying Code §1563(a)(1), (2) and (3) for purposes of determining a controlled group of
corporations and in applying Treas. Reg. §1.414(c)-2 for purposes of determining trades or businesses that are under common control, as provided in Treas. Reg. §1.409A-1(h)(3), the language “at least 80 percent” is used, instead
of the default language “at least 50 percent” as set forth in Treas. Reg. §1.409A-1(h)(3), each place it appears. 
 (c) For purposes of this Agreement, a “409A Change in Control” shall mean a Change in Control that also constitutes a “change in control event” within the meaning of Treasury
Regulation Section 1.409A-3(i)(5). 

  
 2 

 4. Dividends and Dividend Equivalents. No dividends or dividend equivalents shall
accrue or be paid with respect to any outstanding Restricted Stock Units. 
 5. Rights of Stockholder. The Grantee will
not have any rights as a Stockholder with respect to any Restricted Stock Units unless and until the Restricted Stock Units are settled in shares of Stock and Grantee becomes the holder of record of such shares. 

6. No Right to Continued Board Membership. This Agreement does not confer upon the Grantee any right to continuance of membership
on the Board, nor shall it interfere in any way with the right of the Company to terminate his Board membership at any time. 

7. Transferability. The Restricted Stock Units may not, at any time prior to settlement, be assigned, alienated, pledged,
attached, sold or otherwise transferred or encumbered by the Grantee and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable. 

8. Notice. Every notice or other communication relating to this Agreement shall be in writing, and shall be mailed to or delivered
to the party for whom it is intended at such address as may from time to time be designated by it in a notice mailed or delivered to the other party as herein provided; provided that, unless and until some other address be so designated, all notices
or communications by the Grantee to the Company shall be mailed or delivered to the Company at its New York office and all notices or communications by the Company to the Grantee may be given to the Grantee personally or may be mailed to the
Grantee’s home address as reflected on the books of the Company. 
 9. Arbitration. All disputes between the parties
arising out of, or in connection with the validity, interpretation, construction, meaning or execution of the Plan or of this Agreement or any settlement thereof, shall be finally settled by arbitration to be held in New York City and conducted in
accordance with the Rules of the American Arbitration Association. Judgment upon the award rendered may be entered in any court having jurisdiction or application may be made to such court for judicial acceptance of the award and an order of
enforcement, as the case may be. 
 10. Governing Law. The validity, interpretation and performance of this Agreement
shall be controlled by and construed under the laws of Delaware, without giving effect to the principles of conflicts of law. 

11. Signature in Counterparts. This Agreement may be signed in counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.

 Attention: Corporate Trust Administration 
  

	 	Re:	Quality Distribution, LLC/QD Capital Corporation 

 Ladies and Gentlemen: 
 We have acted as special counsel to Quality Distribution,
LLC, a Delaware limited liability company (“Quality Distribution”), QD Capital Corporation, a Delaware corporation (“QD Capital,” and together with Quality Distribution, the “Issuers”). We are
providing this opinion to you at the request of the Issuers pursuant to the Indenture, dated as of November 3, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “Indenture”), among the
Issuers, the guarantors party thereto (the “Guarantors”) and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”), relating to the 9.875% Second-Priority Senior Secured Notes due 2018 of the
Issuers. Reference is hereby made to (i) the Second Supplemental Indenture, of even date herewith (the “Supplemental Indenture”), among the Issuers, QC Environmental Services, Inc., a North Dakota corporation, QC Energy
Resources Northwest, LLC, a Delaware limited liability company, QC Energy Resources Texas, LLC, a Delaware limited liability company, QC Energy Logistics, LLC, a Delaware limited liability company, and Quality Bulk Logistics, LLC, a Delaware limited
liability company (each, an “Additional Guarantor” and, collectively, the “Additional Guarantors”), the other Guarantors and the Trustee, in the form attached here to as Exhibit A, (ii) Supplement
No. 2 to the Collateral Agreement dated as of the date hereof (“Supplement No. 2”), between the Additional Guarantors and The Bank of New York Mellon Trust Company, N.A., as Collateral Agent and (iii) the
Acknowledgement to the Intercreditor Agreement dated as of the date hereof by the Additional Guarantor, Bank of America, N.A., as Intercreditor Agent, and the Trustee, as Second Priority Agent (the “Acknowledgment” and, together
with the Supplemental Indenture and Supplement No. 2, the “Transaction Documents”). Capitalized terms used herein and not otherwise defined shall have the respective meanings given to such terms in the Indenture. 

In our capacity as such counsel, we have examined originals, or copies identified to our satisfaction, of those corporate and other
records and documents we considered appropriate. 
 As to relevant factual matters, we have relied upon, among other things, the
factual representations in the Officer’s Certificate delivered to you today by the Issuers (the “Officer’s Certificate”) in the form attached hereto as Exhibit B. In addition, we have assumed, without
independent investigation, the accuracy of the factual statements made in the Officer’s Certificate.

 We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as
originals and the conformity with originals of all documents submitted to us as copies. In addition, we assume that you have received the Officer’s Certificate and the Officer’s Certificate is reasonably satisfactory to you. 

In connection with our opinion, (i) we have read (a) the conditions precedent and the related definitions in the Indenture,
including, but not limited to, those set forth in Sections 4.11, 9.01, 9.03, 9.06, 13.04 and 13.05, (b) the Collateral Agreement dated as of November 3, 2010, among the Issuers, the other pledgors party thereto, and The Bank of New York
Mellon Trust Company, N.A., as Collateral Agent and (c) the Officer’s Certificate delivered to you pursuant to Sections 9.06, 13.04 and 13.05 of the Indenture (the “Officer’s Certificate”), a copy of which is attached
to this opinion letter as Exhibit B, (ii) the nature and scope of the examination and investigation upon which such opinion is based included an examination of the Indenture, including the sections of the Indenture referred to above, and
(iii) we believe that we have made such investigation and examination as is reasonably necessary to enable us to express the informed opinion set forth below. 
 As to relevant factual matters, we have, with your consent, relied upon, oral or written statements and representations of officers of the Issuers and Guarantors. We have not independently verified such
factual matters. 
 We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as
originals and the conformity with originals of all documents submitted to us as copies. To the extent the obligations of the Issuers and the Guarantors depend on the enforceability of the Transaction Documents against the other parties thereto, we
have assumed that the Transaction Documents are enforceable against such other parties. 
 On the basis of such examination, our
reliance upon the assumptions stated in this opinion and our consideration of those questions of law we considered relevant, and subject to the limitations and qualifications in this opinion, we are of the opinion that: 

1. All covenants and conditions precedent under the Indenture with respect to the execution and delivery of the Transaction Documents by
the Issuers, the Guarantors and the Trustee have been complied with (including Section 9.03 of the Indenture), the execution and delivery of the Transaction Documents by the Issuers, the Guarantors and the Trustee are permitted by the Indenture
and the amendments to the Indenture set forth in the Supplemental Indenture are authorized or permitted by the Indenture. 
 2.
The Transaction Documents (i) are the legal, valid and binding obligation of the Issuers and the Guarantors, enforceable against them in accordance with their terms, except as 

 O’MELVENY & MYERS LLP

 The Bank of New York Mellon Trust Company 
 August 1, 2012 
 Page 3 
  
 
may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors’ rights generally (including, without limitation, fraudulent
conveyance laws) and by general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of
whether considered in a proceeding in equity or at law and possible judicial action giving effect to governmental actions or foreign laws affecting creditors’ rights and (ii) comply with the provisions of the Indenture (including
Section 9.03). 
 The opinions as expressed herein are subject to the following qualifications: 

(a) Our opinion in paragraph 2(i) above as to the enforceability of the Transaction Documents is subject to: (i) public policy
considerations, statutes or court decisions that may limit the rights of a party to obtain indemnification against its own gross negligence, willful misconduct or unlawful conduct; (ii) the unenforceability under certain circumstances of
broadly or vaguely stated waivers or waivers of rights granted by law where the waivers are against public policy or prohibited by law; (iii) the unenforceability under certain circumstances of provisions imposing penalties, liquidated damages
or other economic remedies; and (iv) the unenforceability under certain circumstances of provisions appointing one party as trustee for an adverse party or provisions for the appointment of a receiver. 

(b) We express no opinion as to any provision of the Transaction Documents insofar as it purports to grant a right of setoff in respect
of any Issuer’s or Guarantor’s assets to any person other than a creditor of such Issuer or Guarantor. 
 (c) We
advise you that any provision of the Transaction Documents that provides for exclusive or non-exclusive jurisdiction of the courts of a particular state and federal courts sitting in that state may not be binding on the courts in the forum(s)
selected or excluded. 
 The law covered by this opinion is limited to the present law of the State of New York and the present
Trust Indenture Act of 1939. We express no opinion as to the laws of any other jurisdiction and no opinion regarding the statutes, administrative decisions, rules, regulations or requirements of any county, municipality, subdivision or local
authority of any jurisdiction. 
 This opinion is furnished by us as counsel for the Issuers and may be relied upon by you, as
Trustee, only in connection with the execution and delivery of the Transaction Documents and related matters. It may not be used or relied upon by you for any other purpose or by any other person, nor may copies be delivered to any other person
without in each instance our prior written consent. This opinion is expressly limited to the matters set forth above, and we render no opinion, whether by implication or otherwise, as to any other matters. We assume no obligation to update or
supplement this opinion to reflect any facts or circumstances that arise after the date of this opinion and come to our attention, or any future changes in laws. 

 

	
	Very truly yours,

 SUPPLEMENT NO. 2 dated as of August 1, 2012 (this “Supplement”), to
the Collateral Agreement dated as of November 3, 2010 (the “Collateral Agreement”), among QUALITY DISTRIBUTION, LLC, a Delaware limited liability company (“QD LLC”), QD CAPITAL CORPORATION, a Delaware
Corporation (together with QD LLC, the “Issuers”), QUALITY DISTRIBUTION, INC., each Subsidiary of QD LLC identified on Schedule I thereto or otherwise identified herein as a party (each, a “Subsidiary Pledgor” and
collectively, the “Subsidiary Pledgors”) and THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A. as collateral agent for the Secured Parties (in such capacity, the “Collateral Agent”). 

A. Reference is made to the Indenture dated as of November 3, 2010 (as amended, restated, supplemented, waived or otherwise modified
from time to time, the “Indenture”), among the Issuers, Holdings, and THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee (the “Trustee”). 

B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Indenture and the
Collateral Agreement. 
 C. The Pledgors have entered into the Collateral Agreement in order to induce to induce the Trustee to
enter into the Indenture, and to induce the Holders of the Notes to purchase the Notes. Section 9.16 of the Collateral Agreement provides that additional Subsidiaries may become Subsidiary Pledgors under the Collateral Agreement by execution
and delivery of an instrument in the form of this Supplement. Each undersigned Subsidiary (each, a “New Subsidiary” and, collectively, the “New Subsidiaries”) is executing this Supplement in accordance with the
requirements of the Indenture to become a Subsidiary Pledgor under the Collateral Agreement as consideration for the entry by the Trustee into the Indenture and the purchase of the Notes by the Holders. 

Accordingly, the Collateral Agent and each New Subsidiary agree as follows: 

SECTION 1. In accordance with Section 9.16 of the Collateral Agreement, each New Subsidiary by its signature below becomes a
Subsidiary Pledgor under the Collateral Agreement with the same force and effect as if originally named therein as a Subsidiary Pledgor, and each New Subsidiary hereby (a) agrees to all the terms and provisions of the Collateral Agreement
applicable to it as a Subsidiary Pledgor thereunder and (b) represents and warrants that the representations and warranties made by it as a Pledgor thereunder are true and correct, in all material respects, on and as of the date hereof. In
furtherance of the foregoing, each New Subsidiary, as security for the payment and performance in full of the Obligations (as defined in the Collateral Agreement), does hereby create and grant to the Collateral Agent, for the ratable benefit of the
Secured Parties, a security interest in and Lien on all such New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Collateral Agreement) of such New Subsidiary. Each reference to a “Subsidiary
Pledgor” or “Pledgor” in the Collateral Agreement shall be deemed to include the New Subsidiary. The Collateral Agreement is hereby incorporated herein by reference. 

SECTION 2. Each New Subsidiary represents and warrants to the Collateral Agent and the other Secured Parties that this Supplement has
been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance 

 
with its terms, subject to (i) the effects of bankruptcy, insolvency, moratorium, reorganization, fraudulent conveyance or other similar laws affecting creditors’ rights generally,
(ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) implied covenants of good faith and fair dealing. 

SECTION 3. This Agreement may be executed in two or more counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract. This Supplement shall become effective when (a) the Collateral Agent shall have received a counterpart of this Supplement that bears the signature of each New Subsidiary and (b) the
Collateral Agent has executed a counterpart hereof. 
 SECTION 4. Schedules I, II, III, IV, V and VI and to the Collateral
Agreement are hereby amended by supplementing such Schedules with the information for the New Subsidiaries contained in Annexes A, B, C, D, E and F attached hereto. 
 SECTION 5. Except as expressly supplemented hereby, the Collateral Agreement shall remain in full force and effect. 
 SECTION 6. THIS SUPPLEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS SUPPLEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 

SECTION 7. In the event any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable
in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Collateral Agreement shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 

SECTION 8. All communications and notices hereunder shall be in writing and given as provided in Section 9.01 of the Collateral
Agreement. 
 SECTION 9. Each New Subsidiary agrees to reimburse the Collateral Agent for reasonable out-of-pocket expenses in
connection with this Supplement, including the reasonable fees, disbursements and other charges of counsel for the Collateral Agent. 
 SECTION 10. The recitals contained herein shall be taken as the statements of the New Subsidiaries, and the Collateral Agent assumes no responsibility for their correctness. The Collateral Agent makes no
representations as to the validity or sufficiency of this Supplement.

 ACKNOWLEDGEMENT OF INTERCREDITOR AGREEMENT 

This Acknowledgement of Intercreditor Agreement (this “Acknowledgement”) dated as of August 1, 2012 by the
undersigned is made in reference to the Intercreditor Agreement, dated as of November 3, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “Intercreditor Agreement”), among Bank of America,
N.A., as Intercreditor Agent, and The Bank of New York Mellon Trust Company, N.A., as Second Priority Agent. 
 Reference is
also made to (i) the Credit Agreement dated as of August 19, 2011 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), among Quality Distribution, LLC, (the
“Company”), Quality Distribution, Inc. (“Holdings”), Bank of America, N.A., as administrative and collateral agent, and the lenders and other agents party thereto and (ii) the Indenture, dated as of
November 3, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “Indenture”), among the Company, QD Capital Corporation, a Delaware corporation, (together with the Company, the
“Issuers”), the guarantors party thereto, and The Bank of New York Mellon Trust Company, N.A., as trustee, relating to the 9.875% Second-Priority Senior Secured Notes due 2018 of the Issuers. 

Capitalized terms used in this Acknowledgement and not otherwise defined herein shall have the meanings set forth in the Intercreditor
Agreement. 
 Each of the undersigned Loan Parties (each, a “Grantor”) consents to the terms of the
Intercreditor Agreement. Each Grantor agrees not to take any action that would be contrary to the provisions of the Intercreditor Agreement and agrees that, except as otherwise provided therein, including with respect to those provisions of which
the Company is an intended third party beneficiary, no Second Priority Agent, First Lien Agent, Senior Lender or Second Priority Secured Party shall have any liability to the Grantor for acting in accordance with the provisions of the Intercreditor
Agreement, the Credit Agreement, the Indenture and other collateral, security and credit documents referred to therein. Each Grantor understands that it is not an intended beneficiary or third party beneficiary of the Intercreditor Agreement except
that it is an intended beneficiary and third party beneficiary thereof with the right and power to enforce with respect to Sections 5.1, 5.3, 5.7, 8.3 (solely with respect to the final sentence thereof), 8.16 and 8.22 thereof and as otherwise
provided therein. Each Grantor agrees to be bound by Section 8.22 of the Intercreditor Agreement. 
 Notwithstanding
anything to the contrary in the Intercreditor Agreement or provided herein, each of the undersigned and each party to the Intercreditor Agreement agree, on behalf of itself and in its capacity as agent under the Intercreditor Agreement, that
(i) Holdings, the Company and the other Grantors shall not have any right to consent to or approve any amendment, modification or waiver of any provision of the Intercreditor Agreement except to the extent their rights are adversely affected
(in which case the Company shall have the right to consent to or approve any such amendment, modification or waiver) and (ii) upon the Company’s request in connection with a designation of additional obligations as Other First Priority
Lien Obligations or Future Second Lien Indebtedness, any First Lien Agent and/or any Second Priority Agent shall enter into such supplemental agreements (which may each take the form of a joinder to the Intercreditor Agreement) to facilitate the
designation of such additional obligations as contemplated by Section 8.22 of the Intercreditor Agreement as the Company may request. 

 Without limitation of the Intercreditor Agreement, the undersigned agree, at the
Company’s expense, to take such further action and to execute and deliver such additional documents and instruments (in recordable form, if requested) as any of the Company, the Intercreditor Agents, the Trustee or any other First Lien Agent or
Second Priority Agent may reasonably request to effectuate the terms of the Intercreditor Agreement. 
 THIS ACKNOWLEDGEMENT
SHALL BE INTERPRETED, AND THE RIGHTS AND LIABILITIES OF THE BOUND HEREBY DETERMINED, IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 
 This Acknowledgement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but
all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same
document. Delivery of an executed counterpart of this Acknowledgement by telefacsimile or electronic mail shall be equally as effective as delivery of an original executed counterpart of this Acknowledgement. Any party delivering an executed
counterpart of this Acknowledgement by telefacsimile or electronic mail also shall deliver an original executed counterpart of this Acknowledgement but the failure to deliver an original executed counterpart shall not affect the validity,
enforceability, and binding effect of this Acknowledgement.
