In particular, we have not reviewed any document (other than the documents listed in paragraphs (a) through (q) above) that is referred to in or incorporated by reference into any document reviewed by us. We have assumed that there exists no provision in any document that we have not reviewed that is inconsistent with the opinions stated herein. We have conducted no independent factual investigation of our own but rather have relied solely upon the foregoing documents, the statements and information set forth therein and the additional matters recited or assumed herein, all of which we have assumed to be true, complete and accurate in all material respects.

        With respect to all documents examined by us, we have assumed that (i) all signatures on documents examined by us are genuine, (ii) all documents submitted to us as originals are authentic, (iii) all documents submitted to us as copies conform with the original copies of those documents, and (iv) the documents, in the forms submitted to us for our review, have not been and will not be altered or amended in any respect material to our opinions expressed herein.

extent provided in paragraphs 3, 7 and 11 below, the due authorization, execution and delivery by all parties thereto of all documents examined by us, and (viii) that each of the documents examined by us constitutes a valid and binding agreement of the parties thereto, and is enforceable against the parties thereto, in accordance with its terms. We have not participated in the preparation of any offering material relating to any of the Companies and assume no responsibility for the contents of any such material.

        This opinion is limited to the laws of the State of Delaware (excluding the insurance, securities and blue sky laws of the State of Delaware), and we have not considered and express no opinion on the laws of any other jurisdiction, including federal laws and rules and regulations relating thereto. Our opinions are rendered only with respect to Delaware laws and rules, regulations and orders thereunder that are currently in effect.

        Based upon the foregoing, and upon our examination of such questions of law and statutes of the State of Delaware as we have considered necessary or appropriate, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that:

        1.     Each of the Corporations has been duly incorporated and is validly existing in good standing as a corporation under the General Corporation Law of the State of Delaware (8Del.C. §101,etseq.) (the "DGCL").

        2.     Each of the Corporations has all necessary corporate power and authority under the DGCL, its Certificate of Incorporation and its Bylaws to execute and deliver, and to perform its obligations under, the Indenture.

        3.     The execution and delivery by each of the Corporations of the Indenture, and the performance by each of the Corporations of its obligations thereunder, have been duly authorized by all necessary corporate action on the part of such Corporation under the DGCL, its Certificate of Incorporation and its Bylaws.

        4.     The execution, delivery and performance by each of the Corporations of the Indenture do not violate (i) its Certificate of Incorporation or its Bylaws, or (ii) the DGCL.

        5.     Each of the LLCs has been duly formed and is validly existing in good standing as a limited liability company under the Delaware Limited Liability Company Act (6Del. C. § 18-101,etseq.) (the "LLC Act").

        6.     Each of the LLCs has all necessary limited liability company power and authority under the LLC Act and its LLC Agreement to execute and deliver, and to perform its obligations under, the Indenture.

        7.     The execution and delivery by each of the LLCs of the Indenture, and the performance by each of the LLCs of its obligations thereunder, have been duly authorized by all

necessary limited liability company action on the part of such LLC under the LLC Act and its LLC Agreement.

        8.     The execution, delivery and performance by each of the LLCs of the Indenture do not violate (i) its LLC Certificate or its LLC Agreement or (ii) the LLC Act.

        9.     RESLP has been duly formed and is validly existing in good standing as a limited partnership under the Delaware Revised Uniform Limited Partnership Act (6Del. C. § 17-101,etseq.) (the "LP Act").

        10.   Under the LP Act and the RESLP Partnership Agreement, RESLP has all necessary partnership power and authority to execute and deliver, and to perform its obligations under, the Indenture.

        11.   Under the LP Act and the RESLP Partnership Agreement, the execution and delivery by RESLP of the Indenture, and the performance by RESLP of its obligations thereunder, have been duly authorized by all necessary partnership action on the part of RESLP.

        12.   The execution, delivery and performance by RESLP of the Indenture do not violate (i) the RESLP Certificate or the RESLP Partnership Agreement or (ii) the LP Act.

        The opinions expressed above are subject to the following additional assumptions, qualifications, limitations and exceptions:

        A.    We note that notwithstanding any covenants to the contrary contained in the Indenture: (i) the stockholders of any of the Corporations may dissolve such Corporation under Section 275(c) of the DGCL upon the consent of all the stockholders entitled to vote thereon, (ii) a stockholder owning at least 90% of the outstanding shares of each class of stock of any of the Corporations entitled to vote thereon may effect a merger with such Corporation under Section 253 or Section 267 of the DGCL, (iii) the stockholders of each of the Corporations may amend the Bylaws of such Corporation, (iv) a member or manager of any of the LLCs has the right or power to apply to or petition a court to decree a dissolution of such LLC pursuant to Section 18-802 of the LLC Act, and (v) a partner of RESLP has the right or power to apply to or petition a court to decree a dissolution of RESLP pursuant to Section 18-802 of the LP Act.

        B.    We have assumed that (i) at all times since the formation of American Medical until February 10, 2005, American Medical (A) was governed by an oral or written limited liability company agreement, and (B) did not dissolve pursuant to its limited liability company agreement or by operation of law, and (ii) at all times since the formation of RESLP until July 24, 1996, RESLP (A) was governed by a written partnership agreement, (B) did not dissolve pursuant to its partnership agreement or by operation of law, and (C) any amendment or restatement of the partnership agreement of RESLP then in effect was accomplished in

Furthermore, we consent to the filing of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement (the "Registration Statement") on Form S-4, relating to the Offer to Exchange $950,000,000 Outstanding 8.125% Senior Notes due 2019 for $950,000,000 Registered 8.125% Senior Notes due 2019, as proposed to be filed by Emergency Medical Services Corporation, a Delaware corporation, and the other registrants thereunder with the Securities and Exchange Commission on or about the date hereof.
