                               GUARANTY AGREEMENT

      THIS GUARANTY AGREEMENT (the "Guaranty Agreement"), dated as of March 24,
1999 (the "Execution Date"), is by and between Vestar Capital Partners III, L.P.
("VCP") to Sheridan Healthcare, Inc. ("Sheridan").

                             PRELIMINARY STATEMENTS

      1. Sheridan, Vestar/Calvary Holdings, Inc. ("VCHoldings") and Vestar
Calvary, Inc. ("VCI") have entered into an Agreement and Plan of Merger dated as
of March __, 1999 (the "Merger Agreement").

      2. As a condition and inducement to Sheridan's entering into the Merger
Agreement, VCP has agreed to guarantee full and prompt payment of VCI's
obligations to Sheridan under Section 8.2(d) of the Merger Agreement ("VCI's
Obligations"), pursuant to the terms of this Guaranty Agreement.

      In consideration of the mutual covenants contained in this Guaranty
Agreement, the parties agree as follows:

                                    AGREEMENT

      1. Guaranty. VCP unconditionally, absolutely, continually and irrevocably
guarantees to Sheridan the prompt payment in full of VCI's Obligations.

      2. Payment. If VCI shall default in payment or performance of any of VCI's
Obligations when they become due, then VCP, promptly upon Sheridan's demand,
shall fully pay to Sheridan an amount equal to all of VCI's Obligations then due
and owing.

      3. Unconditional Obligation. This is a guaranty of payment and not of
performance or collection. It is the purpose and intent of the parties that
VCP's guaranty of VCI's obligations shall be absolute and unconditional and
shall not be discharged except by payment as provided in this Guaranty
Agreement.

      4. Currency and Funds of Payment. VCP guarantees that VCI's Obligations
shall be paid in lawful currency of the United States of America and in
immediately available funds, regardless of any law, regulation or decree now or
hereafter in effect.

      5. Waiver; Subrogation; Subordination.

            (a) VCP waives notice of the following events or occurrences; (i)
Sheridan's acceptance of this Guaranty Agreement; (ii) Sheridan, VCI and
VCHoldings, now or at any time hereafter, obtaining, amending, substituting for,
releasing, waiving or modifying the Merger 
   2

Agreement and any of the Other Documents; (iii) presentment, demand, notices of
default, non-payment, partial payment and protest; (iv) Sheridan, now or at any
time hereafter, granting to VCI any indulgence or extensions of time of payment
of VCI's Obligations; and (v) Sheridan, now or at any time hereafter, accepting
from VCI or any other person, any partial payment or payments on account of
VCI's obligations or settling, subordinating, compromising, discharging or
releasing the same. VCP agrees that Sheridan may now or at any time hereafter do
any or all of the foregoing in any manner, upon any terms and at any times as
Sheridan, in its sole and absolute discretion, deems advisable, without in any
way or respect impairing, affecting, reducing or releasing VCP from its
obligations under this Guaranty Agreement, and VCP consents to each and all of
the foregoing events or occurrences.

            (b) VCP agrees that payment by VCP may be enforced by Sheridan and
VCP expressly waives any right it may have to require Sheridan to prosecute
collection or seek to enforce or resort to any remedies against VCI.

            (c) Until all of VCI's Obligations are paid in full, VCP
unconditionally subordinates all present and future debts, liabilities or
obligations of VCI and until all of VCI's Obligations have been fully satisfied,
all amounts due to VCP from VCI under such debts, liabilities, or obligations
shall be collected and held by VP as agent and bailee of Sheridan separate and
apart from all other funds, property and accounts of VCP.

      6. Effectiveness; Enforceability. This Guaranty Agreement shall be
effective as of the Execution Date and shall continue in full force and effect
until all of VCI's Obligations are fully paid or the merger contemplated by the
Merger Agreement has been consummated. This Guaranty Agreement shall be binding
upon and inure to the benefit of VCP and Sheridan and their respective
successors and assigns. Notwithstanding the foregoing, VCP may not, without the
prior written consent of Sheridan, assign any rights, powers duties or
obligations hereunder.

      7. Representations and Warranties. VCP represents and warrants to Sheridan
that it is duly authorized to execute, deliver and perform this Guaranty
Agreement, that this Guaranty Agreement is legal, valid, binding and enforceable
against VCI in accordance with its terms except as enforceability may be limited
by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the enforcement of credits' rights generally and by general equitable
principles; and that VCP's execution, delivery and performance of this Guaranty
Agreement does not violate or constitute a breach of its governing documents or
any agreement to which VCP is a party or any applicable laws.

      8. Miscellaneous. VCP agrees to be liable for the payment of all
reasonable fees and expenses, including attorney's fees, costs and expenses (at
both trial and appellate levels), incurred by Sheridan in connection with the
enforcement of this Guaranty Agreement if VCP fails to perform its obligations
hereunder. This Guaranty Agreement and Section 8.2(d) of the Merger Agreement
constitute the entire agreement among the parties with 
   3

respect to the subject matter hereof and supersede all prior agreements and
understandings among the parties with respect thereto. No addition to or
modification of any provision of this Guaranty Agreement shall be binding upon
any party hereto unless made in writing signed on behalf of each of the parties
to it. This Agreement may be executed by the parties in separate counterparts,
each of which when so executed and delivered shall be an original, but all such
counterparts shall together constitute one and the same instrument. Headings of
this Guaranty Agreement are for the convenience of the parties only and shall be
given no substantive or interpretive effect whatsoever. In this Agreement,
unless the context otherwise requires, words describing the singular number
shall include the plural and vice versa, and words denoting any gender shall
include all genders and words denoting natural persons shall include
corporations and partnerships and vice versa. Except as provided in this
Guaranty Agreement, no action taken pursuant to this Guaranty Agreement,
including, without limitation, any investigation by or on behalf of any party,
shall be deemed to constitute a waiver by the party taking such action of
compliance with any representations, warranties, covenants or agreements
contained in this Agreement. The waiver by any party of a breach of any
provision hereunder shall not operate or be construed as a waiver of any prior
or subsequent breach of the same or any other provision. Any term or provision
of this Guaranty Agreement which is invalid or unenforceable in any jurisdiction
shall, as to that jurisdiction, be ineffective to the extent of such invalidity
or unenforceability without rendering invalid or unenforceable the remaining
terms and provisions of this Guaranty Agreement or affecting the validity or
enforceability of any of the terms or provisions of this Guaranty Agreement in
any other jurisdiction. If any provision of this Guaranty Agreement is so broad
as to be unenforceable, the provision shall be interpreted to be only so broad
as is enforceable.

      9. Notices. All notices required or permitted to be given hereunder shall
be in writing and may be delivered by hand, by facsimile, by nationally
recognized private courier, or by United States mail. Notices delivered by mail
shall be deemed given five (5) business days after being deposited in the United
States mail, postage prepaid, registered or certified mail. Notices delivered by
hand, by facsimile, or by nationally recognized private carrier, shall be deemed
given on the day following receipt; provided, however, that a notice delivered
by facsimile shall only be effective if such notice is also delivered by hand,
or deposited in the United States mail, postage prepaid, registered or certified
mail, on or before two (2) business days after its delivery by facsimile. All
notices shall be addressed as follows:
