PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Section 18-108 of the Delaware Limited Liability Company Act (the “Delaware LLC Act”) provides that, subject to such standards and restrictions, if any, as are set forth in a limited liability company’s operating agreement, a limited liability company may, and shall have the power to, indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever. The limited liability company agreement of QD LLC provides that QD LLC shall, to the fullest extent authorized under the Delaware LLC Act, indemnify and hold harmless against all expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered, any manager or officer of QD LLC including indemnification for negligence but excluding indemnification (i) for acts or omissions involving actual fraud, willful misconduct or gross negligence or (ii) with respect to any transaction from which the indemnitee derived an improper personal benefit.

Section 145 of the Delaware General Corporation Law (the “DGCL”) provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Section 145 further provides that a corporation similarly may indemnify any such person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or such other court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

In accordance with Section 102(b)(7) of the DGCL, the certificate of incorporation of QD Capital includes a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omission not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

Section 607.0850 of the Florida Business Corporation Act (the “FBCA”) permits, in general, a Florida corporation to indemnify any person who was or is a party to any proceeding (other than an action by, or in the right of, the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or served another entity in any capacity at the request of the corporation, against liability incurred in connection with such proceeding, including the estimated expenses of litigating the proceeding to conclusion and the expenses actually and reasonably incurred in connection with the defense or settlement of such proceeding, including any appeal thereof, if such person acted in good faith in a manner he or she reasonably believed to be in, or not opposed to the best interests of the corporation and, in criminal actions or proceedings, additionally had no reasonable cause to believe that his or her conduct was unlawful. Section 607.0850(6) of the FBCA permits the corporation to pay such costs or expenses in advance of a final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if he or she is ultimately found not to be entitled to indemnification under the FBCA. Section 607.0850 of the FBCA provides that the indemnification and advancement of expense provisions contained in the FBCA shall not be deemed exclusive of any rights to which a director or officer seeking indemnification or advancement of expenses may be entitled.

In accordance with the provisions of the Amended and Restated Bylaws of QDI, it shall indemnify, to the fullest extent permitted by law, any person who is or was a party, or is threatened to be made a party to, any threatened, pending or contemplated action, suit or other type of proceeding (other than an action by or in our right), whether civil, criminal, administrative, investigative or otherwise, and whether formal or informal, by reason of the fact that such person is or was QDI’s director or our officer or is or was serving at QDI’s request (as a director or officer of another corporation, partnership, joint venture, trust or other enterprise) against judgments, amounts paid in settlement, penalties, fines (including an excise tax assessed with respect to any employee benefit plan) and expenses (including counsel fees) actually and reasonably incurred in connection with any such action, suit or other proceeding, including any appeal thereof, if such person acted in good faith and in a manner such person reasonably believed to be in, or not opposed to, QDI’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any such action, suit or other proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner that such person reasonably believed to be in, or not opposed to, QDI’s best interests or, with respect to any criminal action or proceeding, had reasonable cause to believe that such person’s conduct was unlawful. In addition, QDI also carries insurance on behalf of its directors, officers, employees or agents that may cover liabilities under the Securities Act.

Item 22. Undertakings.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, managers, officers and controlling persons of the Registrants pursuant to the foregoing provisions, or otherwise, the Registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrants of expenses incurred or paid by a director, officer or controlling person of the Registrants in the successful defense of any action, suit or proceeding) is asserted by such director, manager, officer or controlling person in connection with the securities being registered, the Registrants will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by them is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned Registrants hereby undertake:

1. to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement;

(a) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(b) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(c) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

2. that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

3. to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

4. that, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the registrants are subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use;

5. that, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(a) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(b) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(c) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(d) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser;

6. to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request; and

7. to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Re: Registration of Securities of Quality Distribution, LLC and QD Capital Corporation

Ladies and Gentlemen:

At your request, we have examined the Registration Statement on Form S-4 (such registration statement, as amended and supplemented following the date hereof, the “Registration Statement”), of Quality Distribution, LLC, a Delaware limited liability company (the “Company”), and QD Capital Corporation, a Delaware corporation (“QD Capital,” together with the Company, the “Issuers”), in connection with (i) the Issuers’ proposed offer to exchange (the “Exchange Offer”) up to $225,000,000 principal amount at maturity of the Issuers’ 9.875% Second-Priority Senior Secured Notes due 2018 that have been registered under the Securities Act of 1933 (the “Exchange Notes”) for a like principal amount of the Issuers’ outstanding 9.875% Second-Priority Senior Secured Notes due 2018 (the “Existing Notes”) and (ii) guarantees of the Exchange Notes (the “Note Guarantees”) by Quality Distribution, Inc., a Florida corporation and the parent of the Company (“QDI”), and each of the other Guarantors (as defined below).

We have acted as counsel to the Issuers, each of the parties listed on Schedule I hereto (the “Delaware Guarantors” and each a “Delaware Guarantor”), Quality Carriers, Inc., an Illinois corporation (the “Illinois Guarantor”), and each of the parties listed on Schedule II hereto (the “Other Guarantors,” and together with the Delaware Guarantors and the Illinois Guarantor, the “Guarantors”), in connection with the above.

We have examined originals or copies of (i) the Registration Statement, (ii) the Indenture dated as of November 3, 2010 (the “Notes Indenture”) among the Issuers, the Guarantors and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), as trustee (including the Note Guarantees contained therein), under which the Exchange Notes will be issued, (iii) the certificates of incorporation, certificates of formation, operating agreements, bylaws or other organization documents of the Issuers, the Delaware Guarantors and the Illinois Guarantor, and (iv) such other certificates of public officials and of officers and representatives of the Company, statutes and other instruments and documents as were considered appropriate for purposes of the opinions hereafter expressed. We have made such inquiries of officers and representatives of the Company as we have deemed relevant in rendering the opinions hereafter expressed.

Based upon the foregoing, and in reliance thereon, and subject in all respects to the assumptions, exceptions, qualifications and limitations herein set forth, we are of the opinion that:

1. When the Exchange Notes have been duly executed, authenticated and delivered by or on behalf of the Issuers in accordance with the Notes Indenture in exchange for the Existing Notes in accordance with the Notes Indenture and the Exchange Offer, such Exchange Notes will be legally valid and binding obligations of each of the Company and QD Capital, enforceable against each of the Company and QD Capital in accordance with their terms.

2. When the Exchange Notes have been duly executed, authenticated and delivered by or on behalf of the Issuers in accordance with the Notes Indenture and the Exchange Offer, the Note Guarantees of the Guarantors will be the legally valid and binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms.

Our opinion is subject to: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith and fair dealing, and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) we express no opinion as to (a) any provision for liquidated damages, default interest, late charges, monetary penalties, make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies or judicial relief, (c) any provision requiring the payment of attorneys’ fees, where such payment is contrary to law or public policy, (d) any provision permitting, upon acceleration of the Exchange Notes, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon, (e) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitations, trial by jury or at law, or other procedural rights, (f) waivers of broadly or vaguely stated rights, (g) provisions for exclusivity, election or cumulation of rights or remedies, (h) provisions authorizing or validating conclusive or discretionary determinations, and (j) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed (a) the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies, (b) that the Notes Indenture and the Exchange Notes have been duly authorized, executed and delivered by the parties thereto other than the Issuers, the Delaware Guarantors and the Illinois Guarantor, and (c) that the Notes Indenture and the Exchange Notes constitute legally valid and binding obligations of the parties thereto other than the Issuers, the Delaware Guarantors and the Illinois Guarantor, enforceable against each of them in accordance with their respective terms. We have also assumed that the Registration Statement will have become effective and the Exchange Notes will be issued and exchanged in compliance with applicable federal and state securities laws and in the manner described in the Registration Statement.

We have relied solely upon the opinions of (a) Shumaker Loop and Kendrick LLP, insofar as the opinions expressed herein relate to or are dependent upon matters governed by the laws of the State of Florida, (b) Stone Pigman Walther Wittmann L.L.C., insofar as the opinions expressed herein relate to or are dependent upon matters governed by the laws of the State of Louisiana, and (c) Schnader Harrison Segal & Lewis LLP, insofar as the opinions expressed herein relate to or are dependent upon matters governed by the laws of the State of Pennsylvania, in each case, dated the date hereof, a copy of each of which is being filed on the date hereof as an exhibit to the Registration Statement. As to matters of fact, we have relied upon representations of officers of the Company.

Other than as set forth above, the law governed by this opinion is limited to the federal law of the United States of America and the law of the States of New York and Illinois, the Delaware Limited Company Act and the Delaware General Corporation Law. 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 or any jurisdiction.

We hereby consent to the use of this opinion as an exhibit to the Registration Statement and to the reference to this firm under the heading “Legal Matters” in the prospectus constituting part of the Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act of 1933 or the rules and regulations promulgated thereunder.

Re: Registration Statement on Form S-4 of Quality Distribution, LLC, QD Capital Corporation and the Guarantors Named Therein, including Chemical Leaman Corporation, Relating to New 9.875% Second Priority Senior Secured Notes due 2018 (File no. 333-173556)

Ladies and Gentlemen:

We have acted as special counsel in the Commonwealth of Pennsylvania for Chemical Leaman Corporation, a Pennsylvania corporation (“Chemical Leaman”), in connection with the above-referenced Registration Statement (the “Registration Statement”) filed under the Securities Act of 1933, as amended (the “Act”), with the Securities and Exchange Commission (the “Commission”). The Registration Statement relates to the proposed offer by Quality Distribution, LLC, a Delaware limited liability company, and QD Capital Corporation, a Delaware corporation (together, the “Companies”), and the guarantors named therein (the “Guarantors”), including Chemical Leaman, to exchange up to $225,000,000 principal amount of the Companies’ new 9.875% Second-Priority Senior Secured Notes due 2018 (the “Exchange Notes”) for an equal principal amount of the Companies’ outstanding 9.875% Second-Priority Senior Secured Notes due 2018. The Exchange Notes will be guaranteed (the “Note Guarantees”) by the Guarantors, including Chemical Leaman, and will be issued under an Indenture dated as of November 3, 2010 (the “Note Indenture”) among the Companies, the Guarantors, including Chemical Leaman, and the Bank of New York Mellon Trust Company, N.A, as trustee.

In rendering the opinions hereinafter set forth we have examined and relied upon (i) Note Indenture, (ii) originals, or copies certified or otherwise identified to our satisfaction, of the Articles of Incorporation and amendments thereto and By-Laws of Chemical Leaman, (iii) Certificates of the Secretary of Chemical Leaman dated November 3, 2010 and May 24, 2011, and (iv) a certificate of subsistence and good standing of the Corporation issued by the Secretary of the Commonwealth of the Commonwealth of Pennsylvania dated May 20, 2011 (the “Certificate of Good Standing”). We have assumed (x) the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of the documents submitted to us as originals, the conformity with the originals of all documents submitted to us as certified, facsimile or photostatic copies, and the authenticity of the originals of all documents submitted to us as copies, (y) that the Note Indenture and the Exchange Notes have been duly authorized, executed and delivered by the parties thereto, other than Chemical Leaman, and (z) that the Note Indenture and the Exchange Notes constitute legally valid and binding obligations of the parties thereto, other than Chemical Leaman, enforceable against each of them in accordance with their respective terms. We have also assumed that the Registration Statement will have become effective and the Exchange Notes will be issued and exchanged in compliance with applicable federal and state securities laws and in the manner described in the Registration Statement.

Based upon, and solely in reliance upon the review, the limited investigation and the assumptions described above we are of the opinion that:

1. Chemical Leaman is a corporation duly incorporated, validly existing, and in good standing under the laws of the Commonwealth of Pennsylvania.

2. Chemical Leaman has all necessary corporate power and authority to execute, deliver and perform its obligations under the Note Indenture.

3. The execution and delivery of the Note Indenture and the performance of its obligations thereunder have been duly authorized by all necessary corporate action on the part of Chemical Leaman.

4. Chemical Leaman has duly executed and delivered the Note Indenture.

The opinions expressed herein are limited to the laws of the Commonwealth of Pennsylvania and we express no opinion with respect to the laws of any other state or jurisdiction.

We hereby consent to the use of this opinion as Exhibit 5.2 to the Registration Statement and to the reference to us under the caption “Legal Matters” in the prospectus included in the Registration Statement. In giving such consent, we do not hereby admit that we are acting within the category of persons whose consent is required under Section 7 of the Act or the rules or regulations of the Commission thereunder. We express no opinion as to the adequacy or accuracy of any information contained in the Registration Statement or any other disclosure relating to the sale or exchange of the Exchange Notes.

We assume no obligation to revise or supplement our opinions in the event that, after such time as the Registration Statement is declared effective, facts and circumstances come to our attention or changes in the law occur that could affect such opinions.

Re: Exchange Offer by Quality Distribution, LLC and QD Capital Corporation

Ladies and Gentlemen:

At your request, we are delivering this opinion in connection with the Registration Statement on Form S-4, file number 333-173556 (such registration statement, as amended and as supplemented following the date hereof, the “Registration Statement”), of Quality Distribution, LLC, a Delaware limited liability company, and QD Capital Corporation, a Delaware corporation (together, the “Issuers”), in connection with their offer to exchange (the “Exchange Offer”) the Existing Notes for the Exchange Notes, which will be guaranteed by, among others, Quality Distribution, Inc., QD Risk Services, Inc., and Mexico Investments, Inc., each a Florida corporation (the “Florida Guarantors”). All capitalized terms not defined herein shall have the meanings ascribed to them in the Registration Statement.

We have acted as counsel to the Florida Guarantors in connection with the above transaction. In connection with this opinion letter, we have examined originals, or copies certified or otherwise identified to our satisfaction, of those documents identified on Exhibit A attached hereto, the Indenture dated as of November 3, 2010 (the “Indenture”) (including the guarantees of the Florida Guarantors set forth therein (the “Guarantees”)) among the Issuers, the Florida Guarantors and The Bank of New York Mellon Trust Company, N.A., as trustee, and certain other persons, and such other certificates, statutes and other instruments and documents as we have deemed appropriate for purposes of the opinions set forth herein. We have assumed that all signatures not witnessed by us are genuine; all documents submitted to us as originals are authentic; all documents submitted to us as certified or photographic copies conform to the authentic original documents; and all natural persons executing the Indenture had the legal capacity to do so.

Based upon the foregoing, and in reliance thereon, and subject in all respects to the assumptions, exceptions, qualifications and limitations herein set forth, we are of the opinion that:

(1) Each of the Florida Guarantors has been duly incorporated under the Florida Business Corporation Act (“FBCA”) (or prior law), has paid all fees due to the Department of State through December 31, 2011, filed its most recent annual report on April 21, 2011, and its status is active.

(2) Each of the Florida Guarantors has the corporate power and authority to execute and deliver the Indenture and perform the terms and provisions of its Guarantee, and each has taken all necessary corporate action to authorize the execution and delivery of the Indenture and the performance by it of its Guarantee under the Indenture.

(3) Each of the Florida Guarantors has duly executed and delivered the Indenture.

Our opinion is subject to: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith and fair dealing, and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) we express no opinion as to (a) any provision for liquidated damages, default interest, late charges, monetary penalties, make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies or judicial relief, (c) any provision requiring the payment of attorneys’ fees, where such payment is contrary to law or public policy, (d) any provision which might be determined to be usurious or to permit, upon acceleration of the Exchange Notes, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon, (e) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitations, trial by jury or at law, or other procedural rights, (f) waivers of broadly or vaguely stated rights, (g) provisions for exclusivity, election or cumulation of rights or remedies, (h) provisions authorizing or validating conclusive or discretionary determinations, and (j) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed (a) that the Indentures and the Exchange Notes have been duly authorized, executed and delivered by the parties thereto other than the Florida Guarantors and (b) that the Indentures and the Exchange Notes constitute legally valid and binding obligations of the parties thereto other than the Florida Guarantors, enforceable against each of them in accordance with their respective terms. We have also assumed that the Registration Statement will have become effective and the Exchange Notes will be issued and exchanged in compliance with applicable federal and state securities laws and in the manner described in the Registration Statement

This opinion is governed by and limited to the federal law of the United States of America and the law of the State of Florida.
