                              ___________ __, 2000

 To the Lender Parties that are parties to the Credit
    Agreement referred to below, to
    Bank of America, N.A. (formerly NationsBank, N.A.),
    as the Initial Issuing Bank and Swing Line Bank
    thereunder, to Credit Lyonnais,

    of Chicago, and Morgan Guaranty Trust Company
    of New York, as Syndication Agents therefor,
    to Banc of America Securities LLC (formerly

    as the Arranger therefor, and to
    Bank of America, N.A. (formerly NationsBank, N.A.),
    as Administrative Agent for the Lender Parties thereunder


                                CAREMARK RX, INC.

         This opinion is furnished to you pursuant to the Credit Agreement,
dated as of June 9, 1998, among Caremark Rx, Inc. (formerly MedPartners, Inc.),
a Delaware corporation (the "BORROWER"), and each of you, as amended through
Amendment No. 19 to Loan Documents dated as of August 28, 2000 (as so amended,
the "CREDIT AGREEMENT"). Capitalized terms not otherwise defined herein shall
have the same meanings as specified therefor in the Credit Agreement.

         We have acted as special counsel to the Borrower and its Subsidiaries
in connection with the preparation, execution and delivery of the Credit
Agreement.


         In rendering this opinion, we have examined executed (in original,
facsimile or photocopy form) counterparts of the Credit Agreement Amendment, the
Consent to Amendment No. 19 to the Loan Documents dated as of August 28, 2000
(the "CONSENT") executed by each of the Subsidiaries of the Borrower party to
the Subsidiary Guarantee (each a "SUBSIDIARY GUARANTOR") and each of the other
Loan Documents. We have also examined the originals, or copies certified to our
satisfaction, of the documents listed in a certificate of a Responsible Officer
of the Borrower, dated the date hereof (the "OPINION CERTIFICATE"), certifying
that the documents listed in Part A of such Opinion Certificate are the
settlement agreement and transition plan, and all of the material agreements,
instruments and other

documents related thereto, comprising the California Transition Plan (the
"CALIFORNIA TRANSITION PLAN DOCUMENTS") and the documents listed in Part B of
such Opinion Certificate are all of the material loan agreements, indentures,
mortgages, deeds of trust, leases, instruments, contracts and other agreements
and all of the orders, writs, judgments, injunctions, decrees, determinations or
awards, that affect or purport to affect the obligations of the Borrower or any
of its Subsidiaries under any of the Loan Documents, or the right of the
Borrower or any of its Subsidiaries to borrow money, to guarantee the
obligations of other Persons, to create liens on or security interests in their
respective properties or assets, or to consummate the Transactions (as
hereinafter defined), including the following documents submitted to us by the
Borrower (the "OTHER FINANCING DOCUMENTS"):

                  (1)      Indenture dated as of October 8, 1996, between the
                           Borrower, as Issuer, and The First National Bank of
                           Chicago, as Trustee, in respect of the Borrower's
                           $450,000,000 7 3/8% Senior Notes Due 2006 (the
                           "SENIOR NOTES INDENTURE");

                  (2)      Indenture dated as of September 15, 1997, between the
                           Borrower, as Issuer, and PNC Bank, Kentucky, Inc., as
                           Trustee, in respect of the Borrower's $420,000,000 6
                           7/8% Senior Subordinated Notes Due 2000 (the
                           "SUBORDINATED NOTES INDENTURE" and, together with the
                           Senior Notes Indenture, the "INDENTURES")*;

                  (3)      Purchase Contract Agreement dated as of September 15,
                           1997, between the Borrower and The First National

public officials and agreements, instruments and other documents as we have
deemed necessary as a basis for the opinions expressed below. As to questions of
fact material to our opinions, we have, when relevant facts were not

matters set forth in paragraphs 3 and 4 below, federal bankruptcy laws), the
laws of the State of New York and the General Corporation Law of the State of
Delaware, and we express no opinion herein as to the laws of any other
jurisdiction or the effect that any such other laws may have on the matters set
forth herein. Without limiting the foregoing, we express no opinion as to the
effect of any laws, including any restrictions imposed by governmental licenses,
rules, regulations, orders, approvals or similar matters, governing or
applicable to the Borrower or any of the Subsidiary Guarantors, by reason of the
nature of the business conducted by it in any jurisdiction.

         Based upon the foregoing and subject to the limitations and
qualifications hereinafter set forth, we are of the following opinion:


                  1.       The Borrower (a) is a corporation, duly incorporated,
         validly existing and in good standing under the laws of the State of
         Delaware, (b) is duly qualified and in good standing as a foreign
         corporation in the State of Alabama, and (c) has all requisite
         corporate power and authority to own or lease and operate its
         properties and to carry on its business as now conducted and as
         proposed to be conducted.

                  2.       The execution, delivery and performance by the
         Borrower of the California Transition Plan Documents to which it is a
         party are within the corporate powers of the Borrower, have been duly
         authorized by all necessary corporate action, and do not contravene the
         Constitutive Documents of the Borrower. The California Transition Plan
         Documents to which the Borrower is a party have been duly executed and
         delivered.

                  3.       The execution, delivery and performance by the
         Borrower of the California Transition Plan Documents to which it is a
         party do not:

                           (a)      violate any law, rule (including, without
                  limitation, Regulation X of the Board of Governors of the
                  Federal Reserve System), or regulation;


                           (b)      violate any order, writ, judgment,
                  injunction, decree, determination or award set forth in the
                  Opinion Certificate; or

                           (c)      conflict with or result in the breach of, or
                  constitute a default under, or result in or require the
                  creation or imposition of any Lien upon or with respect to any
                  of the property or assets of the Borrower or any of its
                  Subsidiaries under, any of the agreements, instruments or
                  other documents set forth in Part B of the Opinion
                  Certificate.

         The execution, delivery and performance by the Borrower of the
         California Transition Plan Documents to which it is a party, and the
         effectiveness of the California Settlement Agreement and the
         Supplemental Plan Agreement do not conflict with or result in the
         breach of, or constitute a default under, or result in or require the
         creation or imposition of any Lien upon or with respect to any of the
         property or assets of the Borrower or any of its Subsidiaries under,
         any of the Loan Documents.

                  4.       No authorization or approval or other action by, and
         no notice to or filing with, any Governmental Authority or any other
         third party that is a party to any of the agreements, instruments,
         other documents, orders, decrees, determinations or awards set forth in
         the Opinion Certificate is required (under the laws of the State of New
         York, the General Corporation Law of the State of Delaware or the
         federal laws of the United States) for the due execution or delivery by
         the Borrower of the California Transition Plan Documents to which it is
         a party, except for authorizations, approvals, actions, notices and
         filings which have been duly obtained, taken, given or made and are in
         full force and effect.

                  5.       To the best of our knowledge, after due inquiry,
         there is no action, suit, investigation, litigation, arbitration, or
         proceeding pending or threatened against or affecting the Borrower or
         any of its Subsidiaries or any of the property or assets thereof in any
         court or before any arbitrator or by or before any Governmental
         Authority of any kind that purports to affect (x) the legality,
         validity, binding effect or enforceability of the California Transition
         Plan Documents, or (y) the effectiveness of the California Settlement
         Agreement and the Supplemental Plan Agreement, except in the case of
         clauses (x) and (y) above, those proceedings pending in the federal
         bankruptcy court for the approval of the California Transition Plan.

         The opinions set forth above are subject to the following
         qualifications:

                  (a)      Our opinion set forth in paragraph 3 above as it
         relates to the Indentures is rendered on the basis of our view that the
         defined term "Indebtedness" in the Indentures should not be construed
         to include the obligations of the Borrower or MPN under the California
         Transition Plan Documents. Although we believe that our view represents
         the better interpretation, we note that the proper interpretation is a
         matter that is not free from doubt.

                  (b)      In connection with our opinion set forth in paragraph
         3 above as it relates to the Credit Agreement, we express no opinion as
         to (i) whether the agreement of the Borrower to deposit funds into the
         California Deposit Account (as such term is defined in the California
         Settlement Agreement) pursuant to Section 3.5(c) of the California
         Settlement Agreement and to apply such funds as provided in the
         California Settlement Agreement, or the performance by the Borrower of
         such agreement, constitutes a "preference or encumbrance of any kind
         (including, without limitation, any agreement to give any of the
         foregoing)" or "deposit arrangement...intended as, or having the effect
         of, security" as such terms are used in the definition of "Lien"
         appearing in Section 1.01 of the Credit Agreement, and (ii) if so,
         whether such agreement or performance thereof violates Section 5.02(a)
         of the Credit Agreement.

                  (c)      We note that in an action styled [description of
         Alabama TAPS litigation to be inserted], the plaintiffs named therein
         have asserted that one or more of the actions or events contemplated by
         or provided in the California Transition Plan Documents constitute a
         "Termination Event" within the meaning of the TAPS Purchase Agreement.
         We further note that we do not represent the Borrower in such action
         and, with respect to our opinion set forth in paragraph 3 above as it
         may relate to the TAPS Purchase Agreement, we express no opinion as to
         whether the execution, delivery or performance by the Borrower of the
         California Transition Plan Documents constitutes a "Termination Event"
         within the meaning of the TAPS Purchase Agreement.

                  (d)      For purposes of rendering the opinions set forth
         above, we have relied, with your permission and without independent
         verification, upon the opinion(s) attached hereto of [___________]*,
         special California counsel to the Borrower and its Subsidiaries,
         addressed to the Agents and the Lender Parties, as to the matters set
         forth therein.

         This opinion may not be used or relied upon for any purpose other than
in connection with the transactions contemplated by the Credit Agreement and the
other Loan Documents, or by any person or entity other than the addressees
hereof, without our prior written consent, provided that (i) any of your
permitted successors, assigns or transferees may rely on this opinion in
connection with the transactions contemplated by the Loan Documents as if this
opinion letter were also addressed to them and (ii) you may furnish copies of
this opinion to your independent auditors, legal counsel and appropriate
regulatory authorities and pursuant to an order or legal process of any relevant
government authority.

                                                              Very truly yours,
