Re:     ExamWorks Group, Inc. – Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to ExamWorks Group, Inc., a Delaware corporation (the “Company”) and the guarantors listed on Schedule I hereto (the “Subsidiary Guarantors”), in connection with the registration statement on Form S-3 (the “Registration Statement”) to be filed with the Securities and Exchange Commission (the “Commission”) by the Company on the date hereof under the Securities Act of 1933, as amended (the “Act”), including the prospectus included therein (the “Prospectus”). The Registration Statement relates to the issuance and sale by the Company from time to time, pursuant to Rule 415 of the rules and regulations promulgated under the Act, of an unspecified amount of securities of the Company, consisting of (i) senior debt securities or subordinated debt securities (the “Debt Securities”) to be issued in one or more series under an indenture (the “Indenture”) proposed to be entered into among the Company, the guarantors listed therein and trustees to be named (each, a “Trustee”); and (ii) guarantees of the Debt Securities (the “Subsidiary Guarantees”) by one or more subsidiaries of the Company, including one or more of the Subsidiary Guarantors, for the benefit of Debt Securities. The Debt Securities and Subsidiary Guarantees are collectively referred to herein as the “Offered Securities.” The Registration Statement provides that the Offered Securities may be offered from time to time in amounts, at prices and on terms to be set forth in one or more supplements to the Prospectus (each, a “Prospectus Supplement”). This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

As such counsel and for purposes of our opinions set forth below, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or appropriate as a basis for the opinions set forth herein, including, without limitation:

(i) the Registration Statement;

(ii) the resolutions adopted by the Company's board of directors (the “Board of Directors”), dated April 2, 2015, relating to the registration of the Offered Securities and related matters; and

(iii) the unanimous written consents adopted by the boards of directors or members, as applicable, of the Delaware Guarantors, the Illinois Guarantors, the Texas Guarantors, and the New York Guarantors (set forth on Schedule I hereto), dated April 2, 2015.

In addition to the foregoing, we have made such investigations of law as we have deemed necessary or appropriate as a basis for the opinions and views set forth herein.

In such examination and in rendering the opinions expressed below, we have assumed: (i) that each of the Florida Guarantors and the Michigan Guarantors (each as set forth on Schedule I hereto) is a corporation or limited liability company duly formed and existing under and by virtue of the laws of the State of Florida or Michigan, as applicable, and is in good standing with the Secretary of State of the State of Florida or Michigan, as applicable; (ii) the due authorization, execution and delivery of all documents by all the parties thereto; (iii) the genuineness of all signatures on all documents submitted to us; (iv) the authenticity and completeness of all documents, corporate records, certificates and other instruments submitted to us; (v) that photocopy, electronic, certified, conformed, facsimile and other copies submitted to us of original documents, corporate records, certificates and other instruments conform to the original documents, records, certificates and other instruments, and that all such original documents, corporate records, certificates and other instruments were authentic and complete; (vi) the legal capacity and competency of all individuals executing documents; (vii) that no documents submitted to us have been amended or terminated orally or in writing except as has been disclosed to us; (viii) that the statements contained in the certificates and comparable documents of public officials, officers and representatives of the Company, the Subsidiary Guarantors and other persons on which we have relied for the purposes of this opinion letter are true and correct; (ix) that each of the officers and members of the Board of Directors of the Company and the boards of directors or members, as applicable, of each of the Subsidiary Guarantors, including the boards of directors or members, as applicable, of the Delaware Guarantors, the Illinois Guarantors, the Texas Guarantors, and the New York Guarantors, has properly exercised his or her fiduciary duties; (x) that New York law will be chosen to govern the Debt Securities, the Subsidiary Guarantees and the Indenture and that such choice is legally enforceable, and that the Debt Securities, the Subsidiary Guarantees and the Indenture will contain all provisions required under the laws of the State of Delaware, Texas, New York and Illinois in respect of contracts for the sale of securities issued by a Delaware, Texas, New York, or Illinois corporation or limited liability company, as applicable; (xi) that there are no agreements or understandings between or among the parties to the Debt Securities, the Subsidiary Guarantees or the Indenture that would expand, modify or otherwise affect the terms of such agreements or instruments or the respective rights or obligations of the parties thereunder; and (xii) that the Debt Securities, the Subsidiary Guarantees and the Indenture will conform to the descriptions thereof set forth in the Prospectus. As to all questions of fact material to this opinion letter, we have relied (without independent investigation) upon certificates or comparable documents of officers and representatives of the Company and the Subsidiary Guarantors. Based upon the foregoing, and in reliance thereon, and subject to the limitations, qualifications and exceptions set forth herein, we are of the following opinion:

B. The opinions above are subject to the following qualifications and exceptions:

1.With reference to, but without limiting in any way, qualification (A) above, certain provisions which could be construed as a penalty or forfeiture, provisions indemnifying a party against liability for its own wrongful or negligent acts or otherwise in cases where indemnification could be considered contrary to public policy (including, without limitation, under federal and state securities laws and regulations as interpreted by applicable governmental authorities), provisions exculpating another party from liability or waiving defenses or other rights, provisions to the effect that terms of the documents may not be waived or modified except in writing, provisions regarding the recovery of attorneys’ fees for a person who is not the prevailing party in a final proceeding, provisions imposing a payment obligation with respect to the Company's or any Subsidiary Guarantor’s obligations and provisions whereby a party purports to ratify acts in advance of the occurrence of such acts, are or may be unenforceable in whole or in part under applicable law.

2.No opinion is expressed herein with respect to the validity, binding effect or enforceability of (i) any provision contained in the Offered Securities allowing any party to exercise any remedial rights without notice to the Company or the Subsidiary Guarantors, (ii) any waiver of demand or notice by the Company or any of the Subsidiary Guarantors, or any waiver of any rights or any defense which as a matter of law or public policy cannot be waived, in either case (iii) any provisions contained in the Offered Securities purporting to establish evidentiary standards, (iv) any provision of the Offered Securities which purports to establish the subject matter jurisdiction of the United States District Court to adjudicate any controversy related to any of the Offered Securities, (v) any provision of the Offered Securities which purports to entitle any person or entity to specific performance of any provision thereof, (vi) any provision of the Offered Securities that requires a person or entity to cause another person or entity to take or to refrain from taking action under circumstances in which such person or entity does not control such other person or entity, (vii) any provision of the Offered Securities insofar as it purports to effect a choice of governing law or choice of forum or venue for the adjudication of disputes, (viii) any provision related to the effectiveness of service of process by mail in any suit, action or proceeding of any nature arising in connection with or in any way relating to any Offered Security, (ix) any provision contained in the Offered Securities purporting to limit the liability of any party thereto to third parties or (x) any provision contained in the Offered Securities that constitutes (or is construed to constitute) an agreement to agree.

3.In addition, we express no opinion as to the acceptance by a Federal court located in the State of New York of jurisdiction of a dispute arising under the Offered Securities.

4.No opinion is expressed as to the validity, binding effect or enforceability of any provision of any Offered Security that (i) requires that waivers or amendments must be in writing in so far as it suggests that oral or other modifications, amendments or waivers could not be effectively agreed upon by the parties or that the doctrine of promissory estoppel might not apply; (ii) waives (a) vague or broadly stated rights, (b) future rights, (c) the benefits of statutory, regulatory or constitutional rights, unless and to the extent that the statute, regulation or constitution expressly allows waiver, (d) unknown future defenses, or (e) rights to damages; (iii) states that rights or remedies are not exclusive, that every right or remedy is cumulative and may be exercised in addition to any other right or remedy, that the election of some particular remedy does not preclude recourse to one or more others or that failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy; (iv) imposes penalties, forfeitures, late payment charges or an increase in interest rate upon delinquency in payment or the occurrence of a default; (v) appoints one party as an attorney-in-fact for an adverse party; or (vi) states that time is of the essence.
