                  2.3. Common Stock Unregistered. The Stockholder acknowledges
and represents that he has been advised by the Company that:

                  (a) the offer and sale of the Common Stock have not been and
will not be registered under the Securities Act;

                  (b) the Common Stock must be held indefinitely and the
Stockholder must continue to bear the economic risk of the investment in the
Common Stock unless the offer and sale of such Common Stock is subsequently
registered under the Securities Act and all applicable state securities laws or
an exemption from such registration is available;

                  (c) there is no established market for the Common Stock and it
is not anticipated that there will be any public market for the Common Stock in
the foreseeable future;

                  (d) Rule 144 promulgated under the Securities Act is not
presently available with respect to the sale of any securities of the Company,
and, except as set forth in the Stockholders Agreement, the Company has made no
covenant to make such Rule available;

                  (e) when and if shares of Common Stock may be disposed of
without registration under the Securities Act in reliance on Rule 144, such
disposition can be made only in limited amounts in accordance with the terms and
conditions of such Rule;

                  (f) if the Rule 144 exemption is not available, public offer
or sale of Common Stock without registration will require compliance with some
other exemption under the Securities Act;

                  (g) if any shares of Common Stock are at any time disposed of
in accordance with Rule 144, the Stockholder will deliver to the Company at or

connection with such sale;

                  (h) a restrictive legend in the form set forth in the

and, if the Company should at some time in the future engage the services of a
securities transfer agent, appropriate stop-transfer instructions will be issued
to such transfer agent with respect to the Common Stock.

represents and warrants that:

                  (a) the Stockholder's financial situation is such that he can
afford to bear the economic risk of holding the Common Stock for an indefinite
period of time, has adequate means for providing for his current needs and
personal contingencies, and can afford to suffer a complete loss of his
investment in the Common Stock;
   5
                                                                               5


                  (b) the Stockholder's knowledge and experience in financial
and business matters are such that he is capable of evaluating the merits and
risks of the investment in the Common Stock, as contemplated by this Agreement;

                  (c) the Stockholder understands that the Common Stock is a
speculative investment which involves a high degree of risk of loss of his
investment therein, there are substantial restrictions on the transferability of
the Common Stock and, on the Closing Date and for an indefinite period following
the Closing, there will be no public market for the Common Stock and,
accordingly, it may not be possible for the Stockholder to liquidate his
investment in case of emergency, if at all;

                  (d) the terms of the Stockholders Agreement provide that in
the event that the Stockholder ceases to be an employee of Sheridan, the
Company, Sheridan, Vestar (as defined in the Stockholders Agreement) and their
designated affiliates have the right to repurchase the Common Stock at a price
which may, in certain circumstances, be less than the fair market value of such
stock;

                  (e) the Stockholder understands and has taken cognizance of
all the risk factors related to the purchase of Common Stock and, other than as
set forth in this Agreement, no representations or warranties have been made to
the Stockholder or his representatives concerning the Common Stock or the
Company, its subsidiaries or their prospects or other matters;

                  (f) in making his decision to purchase the Common Stock hereby
subscribed for, the Stockholder has relied upon independent investigations made
by him and, to the extent believed by the Stockholder to be appropriate, his
representatives, including his own professional, financial, tax and other
advisors;

                  (g) the Stockholder has been given the opportunity to examine
all documents and to ask questions of, and to receive answers from, the Company
and its representatives concerning the Company and its subsidiaries and the
terms and conditions of the purchase of the Common Stock and to obtain any
additional information, in each case as the Stockholder or his representatives
deems necessary;

                  (h) all information which the Stockholder has provided to the
Company and its representatives concerning the Stockholder and his financial
position is complete and correct as of the date of this Agreement; and

                  (i) the Stockholder is an "accredited investor" within the

any power or right preclude such party's other or further exercise or the
exercise of any other power or right. The waiver by any party hereto of a breach
of any provision of this Agreement shall not operate or be construed as a waiver
of any preceding or succeeding breach and no failure by either party to exercise
any right or privilege hereunder shall be deemed a waiver of such party's rights
or privileges hereunder or shall be deemed a waiver of such party's rights to

Common Stock up to the product (rounded up to the nearest whole number) of (i)
the quotient determined by dividing (A) the aggregate number of shares of Common
Stock beneficially owned on a fully diluted basis by such Tagging Stockholder
and sought by the Tagging Stockholder to be included in the contemplated
Transfer by (B) the aggregate number of shares of Common Stock beneficially
owned on a fully diluted basis by the Transferring Stockholder and all Tagging
Stockholders and sought by the Transferring Stockholder and all Tagging
Stockholders to be included in the contemplated Transfer and (ii) the total
number of shares of Common Stock proposed to be directly or indirectly
Transferred to the transferee in the contemplated Transfer, and at the same
price per share of Common Stock and upon the same terms and conditions
(including without limitation time of payment and form of consideration) as to
be paid and given to the Transferring Stockholder; provided that a Stockholder
shall not be deemed to beneficially own any shares underlying unexercised
Options unless such Options are vested and exercisable as of the date of the Tag
Notice described in Section 3.5(b); and provided further that in order to be
entitled to exercise its right to sell shares of Common Stock to the proposed
transferee pursuant to this Section 3.5(a), a Tagging Stockholder must agree to
make to the transferee the same representations, warranties, covenants,
indemnities and agreements as the Transferring Stockholder agrees to make in
connection with the proposed Transfer of the shares of Common Stock of the
Transferring Stockholder (except that in the case of representations and
warranties pertaining specifically to the Transferring Stockholder a Tagging
Stockholder shall make the comparable representations and warranties pertaining
specifically to itself); and provided further that all representations,
warranties and indemnities shall be made by Tagging Stockholders severally and
not jointly and that the liability of the Transferring Stockholder and the
Tagging Stockholders (whether pursuant to a representation, warranty, covenant,
indemnification provision or agreement) shall be evidenced in writings executed
by them and the transferee and shall be borne by each of them on a pro rata
basis. Any Tagging Stockholder that is a holder of Common Stock Equivalents and
wishes to participate in a sale of Common Stock pursuant to this Section 3.5(a)
shall convert or exercise or exchange such number of Common Stock Equivalents
into or for Common Stock as may be required therefor on or prior to the closing
date of such Transfer.

            (b) The Transferring Stockholder shall give notice (a "Tag Notice")
to all relevant Stockholders of each proposed Transfer giving rise to the rights
of the Tagging Stockholders set forth in the first sentence of Section 3.5(a) at

payment offered by the proposed transferee and the representations, warranties
and indemnities to be made or given by the Transferring Stockholders, and a
representation that the proposed transferee has been informed of the tag-along
rights provided for in this Section 3.5 and has agreed to purchase shares of
Common Stock in accordance with the terms hereof. The tag-along rights provided
by 

   31
                                                                              15


this Section 3.5 must be exercised by each Tagging Stockholder within 20 days
following receipt of the notice required by the preceding sentence, by delivery
of a written notice to the Transferring Stockholder indicating such Tagging
Stockholder's desire to exercise its rights and specifying the number of shares
of Common Stock it desires to sell. The Transferring Stockholder shall be
entitled under this Section 3.5 to Transfer to the proposed transferee the
number of shares of Common Stock equal to the excess of (x) the number referred
to in clause (ii) of Section 3.5(a) over (y) the aggregate number of shares of
Common Stock set forth in the written notices, if any, delivered by the Tagging
Stockholders pursuant to the preceding sentence (up to the maximum number of
shares of Common Stock beneficially owned by such Tagging Stockholder required
to be purchased by the proposed transferee pursuant to the first sentence of
Section 3.5(a)). If the proposed transferee fails to purchase shares of Common
Stock from any Tagging Stockholder that has properly exercised its tag-along
rights, then the Transferring Stockholder shall not be permitted to make the
proposed Transfer, and any such attempted Transfer shall be void and of no
effect, as provided in Section 3.3 hereof.

            (c) If any of the Tagging Stockholders exercise their rights under
Section 3.5(a), (i) the first shares of Common Stock to be transferred by such
Tagging Stockholder must be Vested Purchased Shares until such Tagging
Stockholder owns no more Vested Purchased Shares, then Option Shares until such
Tagging Stockholder owns no more Option Shares, then any remaining Purchased
Shares and (ii) the closing of the purchase of the Common Stock with respect to
which such rights have been exercised shall take place concurrently with the
closing of the sale of the Transferring Stockholder's Common Stock.

            3.6 Public Offerings, etc. The provisions of Sections 3.5 and 3.7
shall not be applicable to offers and sales of Securities in a Public Offering
or, if such Securities previously have been sold in a Public Offering, pursuant
to Rule 144 under the Securities Act.

            3.7 Drag-Along Rights. So long as this Agreement shall remain in
effect, if any of Vestar and its Affiliates receives an offer from a Third Party
to purchase all or any portion of the outstanding shares of Common Stock and
such offer is accepted by Vestar or such Affiliate, as the case may be, then
each other Stockholder hereby agrees that it will, if requested in writing not
less than 15 days' prior to the requested Transfer date by Vestar or such
Affiliate, Transfer a pro rata number of Securities beneficially owned by it to
such Third Party on the terms of the offer so accepted by Vestar or such
Affiliate, as the case may be; including making the same representations,
warranties, covenants, indemnities and agreements that Vestar or such Affiliate,
as the case may be, agrees to make (except that, in the case of representations
and warranties pertaining specifically to Vestar or such Affiliate, as the case
may be, each other Stockholder shall make the comparable representations and
warranties pertaining specifically to itself); provided that all
representations, warranties and indemnities shall be made by Stockholders
severally and not jointly and that the liability of Stockholders (whether
pursuant to a representation, warranty, covenant, indemnification provision or
agreement) shall be evidenced in writings executed by them and the transferee
and shall be borne by each of them on a pro rata basis; and provided further
that the terms of such offer applicable to any Common Stock beneficially owned
by such other Stockholder are no less favorable than the terms of such offer
applicable to the Common Stock beneficially owned by Vestar or such Affiliate,
as the case may be, and their respective Affiliates (including with respect to
the amount and nature of consideration and time of receipt 

   32
                                                                              16


thereof); and provided further that the first shares of Common Stock Transferred
by such other Stockholder must be Vested Purchased Shares until such other
Stockholder owns no more Vested Purchased Shares, then the Option Shares until
such other Stockholder owns no more Option Shares, then the portion of any
Options then held by such other Stockholder that are then vested and exercisable
(provided in the case of a Transfer of any such portion of the Options that the
Company shall have made acceptable arrangements with the transferee for the same
per share consideration to be paid to such Stockholder for such portion of the
Option as the transferee pays for the shares of Common Stock to be purchased by
the transferee, reduced by the aggregate option exercise price for the
transferred portion of the Options) until no portion of the Options held by such
Stockholder is vested and exercisable, and then any remaining Purchased Shares.

            3.8 Rights of First Refusal. (a) Each Management Investor and their
Permitted Transferees agree that if, prior to a Qualified Public Offering, such
Management Investor or any of its Permitted Transferees receives a bona fide
offer (a "Transfer Offer") to purchase any or all Securities (the "Transfer
Securities") then owned by such Management Investor or such Management
Investor's Permitted Transferees (collectively, the "Management Investor's
Transfer Group") from any Person (the "Offeror") which any member of the
Management Investor's Transfer Group wishes to accept (the "Management Investor
Offeree"), the Management Investor Offeree shall cause the Transfer Offer to be
reduced to writing and shall provide a written notice (the "Transfer Notice") of
such Transfer Offer to the Company, Vestar and Sheridan. The Transfer Notice
shall also contain an irrevocable offer to sell the Transfer Securities to the
Company, Vestar and Sheridan (in the manner set forth below) at a price equal to
the price contained in, and upon the same terms and conditions as the terms and
conditions contained in, the Transfer Offer and shall be accompanied by a true
and complete copy of the Transfer Offer (which shall identify the Offeror, the
Transfer Securities, the price contained in the Transfer Offer and the other
material terms and conditions of the Transfer Offer). At any time within 30 days
after the date of the receipt by the Company, Vestar and Sheridan of the
Transfer Notice, and subject to Section 3.8(c), the Company, Vestar and Sheridan
or any of their designated Affiliates shall have the right and option to
purchase all (but not less than all) of the Transfer Securities covered by the
Transfer Offer either (i) for the same consideration and on the same terms and
conditions as the Transfer Offer or (ii) if the Transfer Offer includes any
consideration other than cash, then, at the sole option of the Company, Vestar,
Sheridan, or any of their designated Affiliates, as applicable, at the
equivalent all cash price, determined in good faith by a majority of the members
of the Company's Board of Directors. If the option referred to in the preceding
sentence is exercised, on or prior to the 60th day after the date of receipt by
the Company, Vestar and Sheridan of the Transfer Notice the Company, Vestar,
Sheridan or any other designated Affiliates, as applicable, shall execute and
deliver to the Management Investor Offeree a written agreement in the form
included in the Transfer Offer, including representations, warranties, covenants
and indemnities, if the Transfer Offer included such written agreement, and
shall pay the relevant cash consideration, by delivering a certified bank check
or checks in (or, if the Management Investor Offeree so elects at least three
business days prior to the closing date in a writing specifying the Management
Investor Offeree's bank account and other wire Transfer instructions, by wire
transferring) the appropriate amount and shall deliver the relevant non-cash
consideration to the Management Investor Offeree against delivery at the
principal office of Sheridan of certificates or other instruments representing
the Transfer Securities so purchased, appropriately endorsed by the Management
Investor Offeree. If at the end of such 30-day period, 

   33
                                                                              17


the Company, Vestar and Sheridan have not delivered written notice of exercise
by them of their right to purchase the Transfer Securities pursuant to this
Section 3.8 or if at the end of such 60-day period, the Company, Vestar and
Sheridan have not tendered the purchase price for such shares in the manner set
forth above, the Management Investor Offeree shall be free for a period of 90
days from the end of such 30- or 60-day period, as applicable, to Transfer not
less than all of the Transfer Securities to the Offeror on the terms and
conditions set forth in the Transfer Notice (including the execution and
delivery of any written agreement in the form included in the Transfer Offer).
Such Offeror shall agree in a writing in form and substance reasonably
satisfactory to the Company to become a party hereto and be bound to the same
extent as the Management Investor Offeree by the provisions hereof. Promptly
after such sale, the Management Investor Offeree shall notify the Company of the
consummation thereof and shall furnish such evidence of the completion and time
of completion of such sale and of the terms thereof as may reasonably be
requested by the Company. If for any reason any Management Investor Offeree does
not Transfer Transfer Securities to the Offeror on the terms and conditions set
forth in the Transfer Notice, or if any Management Investor Offeree wishes to
sell the Transfer Securities on terms other than those set forth in the Transfer
Notice, the provisions of this Section 3.8 shall again be applicable to the
Transfer Securities.

            (b) The closing of the purchase of the Transfer Securities by the
Company, Sheridan, Vestar or any of their designated Affiliates, as appropriate,
upon exercise of its right of first refusal pursuant to Section 3.8(a) shall
take place at the principal office of Sheridan on a date specified by the
Company, Sheridan, Vestar or any of their designated Affiliates, as applicable,
no later than the last day of the 60-day period after the giving of the Transfer
Notice.

            (c) Notwithstanding anything in this Section 3.8 to the contrary,
(i) neither Vestar nor any of its designated Affiliates may exercise a right of
first refusal under this Section 3.8 unless Vestar has received a written notice
from the Company indicating the Company's intention not to exercise such right
of first refusal (a "No ROFR Notice") and (ii) neither Sheridan nor any of its
designated Affiliates may exercise a right of first refusal under this Section
3.8 unless Sheridan has received a No ROFR Notice from Vestar.

            3.9 Participation Right. (a) Except as otherwise set forth in
Section 3.9(b) hereof, the Company shall not issue (an "Issuance") to Vestar or
any of its Affiliates:

            (i) additional shares of Common Stock or Common Stock Equivalents or
      capital stock of the Company other than Common Stock and Common Stock
      Equivalents ("Other Capital Stock"); or

            (ii) any warrants, rights, calls, options or other securities
      exchangeable for or exercisable or convertible into Other Capital Stock or
      any other security other than Common Stock, Common Stock Equivalents or
      Other Capital Stock entitled to participate in the Company's profits
      (collectively, "Other Capital Stock Equivalents");

unless, prior to such Issuance, the Company notifies each Management Investor in
writing of the proposed Issuance and grants to such notified party or, at the
election of such notified party, one of its Affiliates the right (the "Right")
to subscribe for and purchase such additional shares of Common Stock or Other
Capital Stock or such additional shares or units of 

   34
                                                                              18


Common Stock Equivalents or Other Capital Stock Equivalents (collectively,
"Equity Interests") so issued at the same price and upon the same terms and
conditions (including, in the event such Equity Interests are issued as a unit
together with other securities, the purchase of such other securities) as issued
in the Issuance such that:

            (A) in the case of an Issuance in which shares of Common Stock or
      Common Stock Equivalents are to be issued, immediately after giving effect
      to the Issuance and exercise of the Right (including, for purposes of this
      calculation, the issuance of shares of Common Stock upon conversion,
      exchange or exercise of any Common Stock Equivalent issued in the Issuance
      or subject to the Right), the shares of Common Stock beneficially owned by
      the notified party and its Affiliates on a fully diluted basis (rounded to
      the nearest whole share) shall represent the same percentage of the
      aggregate number of shares of Common Stock outstanding on a fully diluted
      basis as was beneficially owned by such notified party and its Affiliates
      and Vestar and its Affiliates, respectively, immediately prior to the
      Issuance; provided, that for purposes of the calculations required by this
      Section 3.9(a)(A) notified parties and their Affiliates shall not be
      deemed to beneficially own any Shares underlying unexercised Options
      unless such Options are vested and exercisable as of the date of the
      Issuance; and

            (B) in the case of an Issuance in which shares of Other Capital
      Stock or Other Capital Stock Equivalents are to be issued, the notified
      party and its Affiliates shall have the Right to acquire a percentage of
      the Other Capital Stock or Other Capital Stock Equivalents to be issued in
      the Issuance equal to the percentage of shares of Common Stock on a fully
      diluted basis that was beneficially owned by such notified party and its
      Affiliates and Vestar and its Affiliates, respectively, immediately prior
      to the Issuance; provided, that for purposes of the calculations required
      by this Section 3.9(a)(B) notified parties and their Affiliates shall not
      be deemed to beneficially own any Shares underlying unexercised Options
      unless such Options are vested and exercisable as of the date of the
      Issuance.

            (b) The Right may be exercised by the notified party at any time by
written notice to the Company received by the Company within 20 days after the
date on which such notified party receives notice from the Company of the
proposed Issuance, and the closing of the purchase and sale pursuant to the
exercise of the Right shall occur at least 15 days (but not later than 180 days)
after the Company receives notice of the exercise of the Right and prior to or
concurrently with the closing of the Issuance. Notwithstanding the foregoing
provisions of this Section 3.9, the Right shall not apply to (i) any Issuance of
Equity Interests pro rata to all holders of Common Stock and Other Capital
Stock, (ii) any Issuance upon the conversion, exercise or exchange of any Common
Stock Equivalent or any Other Capital Stock Equivalent outstanding on the
Closing Date pursuant to the terms thereof, (iii) any Issuance to a Management
Investor or any other employee of the Company pursuant to a management stock
subscription agreement or stock option or other employee benefit plan of the
Company or one of its Subsidiaries, (iv) any Issuance to a member of the Board
of Directors of the Company or a Subsidiary of the Company designated by Vestar
and its Permitted Transferees who is not a director, officer, general partner or
employee of Vestar or Vestar Capital Partners III, L.P. for services rendered as
such to the 

   35
                                                                              19


Board of Directors of the Company or a Subsidiary of the Company, (v) any
Issuance pursuant to a bona fide underwritten public offering pursuant to an
effective registration statement under the Securities Act or (vi) any Issuance
of Mezzanine Securities.

            3.10 Partial Transfers Following a Qualified Public Offering. Each
Senior Management Investor may, during the one year period commencing on the
second anniversary of the first Qualified Public Offering and during each one
year period commencing on each succeeding anniversary of such Qualified Public
Offering thereafter (each such anniversary being referred to as a "Measurement
Date"), Transfer up to 5% of the shares of Vested Purchased Shares and Option
Shares beneficially owned by such Senior Management Investor on the applicable
Measurement Date, subject to Section 3.1(a) hereof; provided, however, that this
provision shall not permit a Senior Management Investor who has already
Transferred (pursuant to any provision of this Agreement which permits Transfers
by Senior Management Investors) the cumulative number of shares of Common Stock
he or she otherwise would be entitled to Transfer pursuant to this Section 3.10
to Transfer any additional shares of Common Stock.

            3.11 Partial Transfers to Cover Option-Related Tax Payments.

            If, at any time prior to the Lapse Date, a Management Investor's
employment with the Company and its Subsidiaries is terminated by the applicable
employer without Cause or by the Management Investor with Good Reason, and
thereafter such Management Investor exercises Options which would otherwise
expire unless so exercised, such Management Investor may Transfer Securities;
provided, that the aggregate purchase price for the Securities being Transferred
shall not exceed the total amount of taxes which such Management Investor's tax
consultant has reasonably advised will be due and owing in respect of such tax
year by such Management Investor as a result of such Management Investor
exercising such Options; and provided, further, that such Transfer shall be
subject to the right of first refusal provisions of Section 3.8.

            3.12 Transfers to Other Management Investors.

            If, at any time prior to the Lapse Date, a Management Investor's
employment with the Company and its Subsidiaries is terminated by the applicable
employer without Cause or by such Management Investor with Good Reason, then at
any time after the conclusion of the Second Call Period, such Management
Investor may Transfer all or any portion of the Securities beneficially owned by
him to one or more of the other Management Investors; provided, however, that if
the proposed purchase price for such Securities which is offered to the other
Management Investors is less than the relevant purchase price under Section
3.13(c), such proposed Transfer hereunder by such Management Investor shall be
subject to the right of first refusal provisions of Section 3.8.

            3.13 Call Right. (a) If, at any time prior to the Lapse Date, a
Management Investor's employment with the Company and its Subsidiaries is
terminated by the applicable employer for Cause, then within 180 days of the
employment termination date, and subject to Section 3.13(e), the Company,
Vestar, Sheridan or any of their designated Affiliates shall have the option to
purchase all or any portion of the Purchased Shares and Option Shares held by
such 

   36
                                                                              20


Management Investor and such Management Investor's Permitted Transferees by
providing written notice of the relevant election (including the number of
Securities to be purchased) to the applicable Management Investor and Permitted
Transferees (a "Call Notice"). The purchase price per share for such Securities
will be the lower of Cost and Fair Market Value on the date of termination of
employment.

            (b) If, at any time prior to the Lapse Date, a Management Investor's
employment with the Company and its Subsidiaries is terminated due to the death
or Disability of such Management Investor, then within 180 days of the
employment termination date (and, with respect to any Option Shares, within 180
days after the date of the last exercise of any Options, if later), and subject
to Section 3.13(e), the Company, Vestar, Sheridan or any of their designated
Affiliates shall have the option to purchase all or any portion of the Purchased
Shares and Option Shares held by such Management Investor and such Management
Investor's Permitted Transferees by providing a Call Notice to the applicable
Management Investor and Permitted Transferees. The purchase price per share for
such Securities will be the greater of Cost and Fair Market Value on the date of
termination of employment.

            (c) If, at any time prior to the Lapse Date, a Management Investor's
employment with the Company and its Subsidiaries is terminated by the applicable
employer without Cause or by such Management Investor with Good Reason, then
within the later of (1) 180 days of the employment termination date (and, with
respect to any Option Shares, within 180 days after the date of the last
exercise of any Options, if later) or (2) ten days after the applicable
Management Investor has rescinded his election to sell all or a portion of his
Purchased Shares which were to be paid for with a Junior Subordinated Note in
connection with the put right set forth in Section 3.14, and subject to Section
3.13(e), the Company, Vestar, Sheridan or any of their designated Affiliates
shall have the option to purchase all or any portion of the Purchased Shares and
Option Shares held by such Management Investor and such Management Investor's
Permitted Transferees by providing a Call Notice to the applicable Management
Investor and Permitted Transferees. The purchase price per share for (A) the
Applicable Percentage of the Purchased Shares and for all Option Shares will be
the greater of (x) Cost or (y) Fair Market Value on the date of termination of
employment and (B) the remaining portion of such Purchased Shares, if any, will
be Cost.

            (d) If, at any time prior to the Lapse Date, a Management Investor's
employment with the Company and its Subsidiaries is voluntarily terminated by
such Management Investor without Good Reason, then within 180 days of the
employment termination date (and, with respect to any Option Shares, within 180
days after the date of the last exercise of any Options, if later), and subject
to Section 3.13(e), the Company, Vestar, Sheridan or any of their designated
Affiliates shall have the option to purchase all or any portion of the Purchased
Shares and Option Shares held by such Management Investor and such Management
Investor's Permitted Transferees by providing a Call Notice to the applicable
Management Investor and Permitted Transferees. The purchase price per share for
the Applicable Percentage of the Purchased Shares and for all Option Shares will
be Fair Market Value on the date of termination of employment and the purchase
price for the remaining portion of the Purchased Shares, if any, will be the
lower of (x) Cost or (y) Fair Market Value on the date of termination of
employment; provided that if such voluntary termination without Good Reason
occurs prior to the second anniversary of the Closing 

   37
                                                                              21


Date, the Purchase Price per share for all Option Shares will be the lower of
(x) Cost or (y) Fair Market Value on the date of termination of employment.

            (e) Notwithstanding anything in this Section 3.13 to the contrary
(i) neither Vestar nor any of its designated Affiliates may exercise a call
right under this Section 3.13 unless Vestar has received written notice from the
Company indicating the Company's intention not to exercise such call right (a
"No Call Notice") and (ii) neither Sheridan nor any of its designated Affiliates
may exercise a call right under this Section 3.13 unless Sheridan has received a
No Call Notice from Vestar.

            (f) In the event that pursuant to Section 3.13(c), Cost exceeds Fair
Market Value on the date of the Management Investor's termination of employment
and none of the Company, Vestar or Sheridan exercises the call right with
respect to the Purchased Shares and Option Shares which it could have purchased
at Cost (the "Cost Securities") during the 180 day period commencing on such
date of termination (the "Initial Call Period"), then the Company, Vestar or
Sheridan (subject once again to the provisions of Section 3.13(e) with respect
to the Second Call Period regardless of whether No Call Notices were issued in
the Initial Call Period) will have an additional right to call the Cost
Securities during the 90-day period commencing on the eighteen-month anniversary
of the Management Investor's termination of employment (the "Second Call
Period") by providing a Call Notice to the applicable Management Investor. The
purchase price per share for such Securities pursuant to Section 3.13(c)(A) will
be the greater of (x) Fair Market Value on the date of termination of employment
and (y) Fair Market Value on the first day of the Second Call Period and the
purchase price for such Securities pursuant to Section 3.13(c)(B) will be the
lower of (x) Cost or (y) Fair Market Value on the first day of the Second Call
Period.

            (g) The completion of the purchases pursuant to Sections 3.13(a),
(b), (c), (d) and (f) shall take place at the principal office of Sheridan on or
prior to the thirtieth (30th) day after the giving of the applicable Call
Notice. The repurchase price for the Securities shall be paid by delivery to the
appropriate Management Investor or Permitted Transferee of a certified bank
check or checks in the appropriate amount payable to the order of such
Management Investor or Permitted Transferee unless Sheridan is the party
exercising such call right and a Financing Default exists or, after giving
effect to such payment would exist, which prohibits such cash payment, in which
case the portion of the cash payment so prohibited shall be made, to the extent
permitted by any loan agreement, indenture or other agreement to which Sheridan
is a party, by Sheridan's delivery of a junior subordinated promissory note
(which shall be subordinated and subject in right of payment to the prior
payment of all indebtedness of Sheridan including, without limitation, any debt
outstanding under any credit agreement and any modifications, renewals,
extensions, replacements and refunding of all such indebtedness) of Sheridan (a
"Junior Subordinated Note") in a principal amount equal to the amount of the
purchase price which cannot be paid in cash, payable in five equal annual
installments commencing on the first anniversary of the issuance thereof and
bearing interest payable annually in arrears at the publicly announced prime
rate of Chase Manhattan Bank, N.A. on the date of issuance. If Sheridan pays all
or any of the purchase price for any of the Securities with a Junior
Subordinated Note, and then resells such Securities for cash, the portion of the
accrued but unpaid interest and, to the extent of any excess, the outstanding
principal amount of the Junior Subordinated Note that is equal to the amount of
such cash proceeds shall become immediately due and payable, unless and to the
extent 

   38
                                                                              22


that payment of such accrued interest or outstanding principal under the Junior
Subordinated Note would constitute or result in a Financing Default. If at any
time after the issuance by Sheridan of a Junior Subordinated Note, the payment
of all or any portion of the amounts outstanding under such Junior Subordinated
Note can be repaid by Sheridan without giving rise to a Financing Default (a
"Permitted Payment"), Sheridan shall, as promptly as practicable but not later
than thirty days after such payment becomes permissible, pay the Permitted
Payment (accrued interest first and then principal) in cash to the applicable
Management Investor or Permitted Transferee by delivery of a certified bank
check to the order of such Management Investor or Permitted Transferee. If
Sheridan cannot pay the purchase price for any Securities subject to a Call
Notice in cash or a Junior Subordinated Note due to any circumstance described
in this subparagraph 9(g), Sheridan shall not be permitted to exercise the
applicable call right.

            3.14 Put Right. (a) If, at any time prior to the Lapse Date, a
Management Investor's employment with the Company and its Subsidiaries is
terminated due to the death or Disability of such Management Investor, then
within 180 days of the employment termination date such Management Investor and
the members of the Family Group of such Management Investor shall have the
option to sell to Sheridan, and Sheridan shall be obligated to purchase, on one
occasion from such Management Investor and the members of the Family Group of
such Management Investor, all or any portion of the Purchased Shares held by
such Management Investor and the members of the Family Group of such Management
Investor by providing written notice of his or their election (including the
number of Securities to be sold) to Sheridan (a "Put Notice"). The purchase
price per share for such Securities will be Fair Market Value on the date of
termination of employment.

            (b) If, at any time prior to the Lapse Date, a Senior Management
Investor's employment with the Company and its Subsidiaries is terminated by the
applicable employer without Cause or by such Senior Management Investor with
Good Reason, then within 180 days of the employment termination date such Senior
Management Investor shall have the option to sell to Sheridan, and Sheridan
shall be obligated to purchase, on one occasion from such Senior Management
Investor a number of Purchased Shares held by such Senior Management Investor
the aggregate purchase price for which under this Section 3.14(b) is not in
excess of the aggregate purchase price paid by such Senior Management Investor
on the Closing Date for all Securities purchased by such Senior Management
Investor on the Closing Date. Such Senior Management Investor shall exercise
such put right by providing a Put Notice to Sheridan. The purchase price per
share for (A) the Applicable Percentage of such Purchased Shares will be Fair
Market Value on the date of termination of employment and (B) the remaining
portion of such Purchased Shares, if any, will be the lower of Cost and Fair
Market Value on the date of termination of employment.

            (c) The completion of the purchase pursuant to Section 3.14 (a)
shall take place at the principal office of Sheridan on or prior to the sixtieth
day after the giving of the Put Notice. The purchase price for the Purchased
Shares included in the Put Notice shall be paid by delivery to the appropriate
Management Investor or the members of his Family Group, as applicable, of a
certified bank check or checks in the appropriate amount payable to the order of
such Management Investor or the members of his Family Group, as applicable,
unless a Financing Default exists or, after giving effect to such payment would
exist, which prohibits such cash 

   39
                                                                              23


payment, in which case the portion of the cash payment so prohibited shall be
made, to the extent permitted by any loan agreement, indenture or other
agreement to which Sheridan is a party, by Sheridan's delivery of a Junior
Subordinated Note in a principal amount equal to the amount of the purchase
price which cannot be paid in cash, payable in five equal annual installments
commencing on the first anniversary of the issuance thereof and bearing interest
payable annually in arrears at the publicly announced prime rate of Chase
Manhattan Bank, N.A. on the date of issuance. If Sheridan intends to pay all or
any portion of the purchase price with a Junior Subordinated Note, Sheridan
shall give the notice of the principal amount of such note at least 15 days
prior to such purchase, and the relevant Management Investor shall have ten days
thereafter to rescind his election to sell all or a portion of his Purchased
Shares to be paid for with such note. If Sheridan pays all or any portion of the
purchase price for any Purchased Shares with a Junior Subordinated Note, and
then resells such Purchased Shares for cash, the portion of the accrued but
unpaid interest and, to the extent of any excess, the outstanding principal
amount of the Junior Subordinated Note that is equal to the amount of such cash
proceeds shall become immediately due and payable, unless and to the extent that
payment of such accrued interest or outstanding principal under the Junior
Subordinated Note would constitute or result in a Financing Default. If at any
time after the issuance by Sheridan of a Junior Subordinated Note, a Permitted
Payment can be made, Sheridan shall, as promptly as practicable but not later
than thirty days after such payment becomes permissible, pay the Permitted
Payment in cash to the applicable Management Investor or the members of his
Family Group, as applicable, by delivery of a certified bank check to the order
of such Management Investor or the members of his Family Group, as applicable.

            (d) The completion of the purchase pursuant to Sections 3.14 (b)
shall take place at the principal office of Sheridan on or prior to the sixtieth
day after the giving of the Put Notice, at which time at least fifty percent of
the purchase price shall be paid. If Sheridan elects to pay less than all of the
purchase price initially, the remaining portion of the purchase price shall be
paid in one payment on or prior to the first anniversary of the giving of the
Put Notice. The purchase price for the Purchased Shares included in the Put
Notice shall be paid by delivery to the appropriate Senior Management Investor
of a certified bank check or checks in the appropriate amount payable to the
order of such Senior Management Investor unless a Financing Default exists or,
after giving effect to such payment would exist, which prohibits such cash
payment, in which case the portion of the cash payment so prohibited shall be
made, to the extent permitted by any loan agreement, indenture or other
agreement to which Sheridan is a party, by Sheridan's delivery of a Junior
Subordinated Note in a principal amount equal to the amount of the purchase
price which cannot be paid in cash, payable in five equal annual installments
commencing on the first anniversary of the issuance thereof and bearing interest
payable annually in arrears at the publicly announced prime rate of Chase
Manhattan Bank, N.A. on the date of issuance. If Sheridan intends to pay all or
any portion of the initial payment of the purchase price with a Junior
Subordinated Note, Sheridan shall give the Senior Management Investor notice of
the principal amount of such note at least 15 days prior to such purchase, and
the relevant Senior Management Investor shall have ten days thereafter to
rescind his election to sell all or a portion of his Purchased Shares to be paid
for with such note. If Sheridan pays all or any portion of the purchase price
for any Purchased Shares with a Junior Subordinated Note, and then resells such
Purchased Shares for cash, the portion of the accrued but unpaid interest and,
to the extent of any excess, the outstanding principal amount of the Junior
Subordinated Note that is equal to the 

   40
                                                                              24


amount of such cash proceeds shall become immediately due and payable, unless
and to the extent that payment of such accrued interest or outstanding principal
under the Junior Subordinated Note would constitute or result in a Financing
Default. If at any time after the issuance by Sheridan of a Junior Subordinated
Note, a Permitted Payment can be made, Sheridan shall, as promptly as
practicable but not later than thirty days after such payment becomes
permissible, pay the Permitted Payment (accrued interest first and then
principal) in cash to the applicable Senior Management Investor by delivery of a
certified bank check to the order of such Senior Management Investor.

            SECTION 4. REGISTRATION RIGHTS

            4.1 Demand Registration.

            (a) Common Stock Request. Upon the written request (a "Request") of
Vestar or its designated Permitted Transferees that the Company effect the
registration under the Securities Act of all or part of the shares of Common
Stock owned or to be acquired upon conversion, exercise or exchange of Common
Stock Equivalents by Vestar and/or its Permitted Transferees (a "Requesting
Stockholder"), the Company will use its best efforts to effect the registration
under the Securities Act of such shares.

            (b) Registration Statement Form. Registrations under this Section
4.1 shall be on such appropriate registration form of the SEC as shall (i) be
selected by the Company and (ii) permit the disposition of the Common Stock
being registered in accordance with the intended method or methods of
disposition specified in the request for such registration. The Company agrees
to include in any such registration statement all information which, in the
opinion of counsel to the underwriters, the Requesting Stockholder and the
Company, is required to be included.

            (c) Effective Registration Statement. A registration requested
pursuant to this Section 4.1 shall not be deemed to have been effected (i)
unless a registration statement with respect thereto has become effective, or
(ii) if after it has become effective, such registration is interfered with by
any stop order, injunction or other order or requirement of the SEC or other
Governmental Authority for any reason not attributable to the Requesting
Stockholder or any of its Affiliates and has not thereafter become effective.

            (d) Limitations on Registration on Request. Notwithstanding anything
in this Section 4.1 to the contrary, in no event will (i) the Company be
required to effect more than one registration pursuant to Section 4.1(a) within
any 180 day period or (ii) the Requesting Stockholder be entitled to more than
five registrations in the aggregate pursuant to Section 4.1(a); unless in the
case of clause (d)(ii) above such Requesting Stockholder agrees to pay all of
the costs and expenses of each such additional registration (unless either (x) a
registration so requested is not deemed to have been effected pursuant to
Section 4.1(c) for a reason not attributable to the Requesting Stockholder or
any of its Affiliates or (y) the number of shares of Common Stock sought to be
included by such Requesting Stockholder in such registration is reduced by more
than 25% pursuant to the provisions of Section 4.2(b)).

   41
                                                                              25


            4.2 Incidental Registration.

            (a) Right to Include Common Stock and Common Stock Equivalents. If
the Company at any time proposes to register any shares of Common Stock (or
Common Stock Equivalents, including any registration of Common Stock Equivalents
pursuant to the exercise of rights under Section 4.2(b)) under the Securities
Act (except registrations on such form(s) solely for registration of Common
Stock or Common Stock Equivalents in connection with any employee benefit plan
or dividend reinvestment plan or a merger or consolidation), including
registrations pursuant to Section 4.1(a), whether or not for sale for its own
account, it will each such time as soon as practicable give written notice of
its intention to do so to all the Stockholders. Upon the written request (which
request shall specify the total number of shares of Common Stock or Common Stock
Equivalents intended to be disposed of by such Stockholder) of any Stockholder
made within 30 days after the receipt of any such notice (15 days if the Company
gives telephonic notice with written confirmation to follow promptly thereafter,
stating that (i) such registration will be on Form S-3 and (ii) such shorter
period of time is required because of a planned filing date), the Company will
use all reasonable efforts to effect the registration under the Securities Act
of all Common Stock held or to be acquired upon conversion, exercise or exchange
of Common Stock Equivalents (or, if Common Stock Equivalents are proposed to be
registered by the Company, Common Stock Equivalents) by the Stockholders which
the Company has been so requested to register for sale in the manner initially
proposed by the Company; provided that the Company shall not be obliged to
register any Common Stock Equivalents which are not of the same class, series
and form as the Common Stock Equivalents proposed to be registered by the
Company. If the Company thereafter determines for any reason not to register or
to delay registration of the Common Stock or Common Stock Equivalents (provided,
however, that in the case of any registration pursuant to Section 4.1(a), such
determination shall not violate any of the Company's obligations under Section
4.1 or any other provision of this Agreement), the Company may, at its election,
give written notice of such determination to the Stockholders and (A) in the
case of a determination not to register, shall be relieved of the obligation to
register such Common Stock or Common Stock Equivalents in connection with such
registration (without prejudice, however, to any right the Requesting
Stockholder may have to request that such registration be effected as a
registration under Section 4.1(a)) and (B) in the case of a determination to
delay registering, shall be permitted to delay registering any Common Stock or
Common Stock Equivalents of a Stockholder for the same period as the delay in
registration of such other securities. No registration effected under this
Section 4.2(a) shall relieve the Company of any obligation to effect a
registration upon a Common Stock Request under Section 4.1(a).

            (b) Priority in Incidental Registration. In a registration pursuant
to this Section 4.2, if the managing underwriter of such underwritten offering
shall inform the Company and the relevant Stockholders by letter of its belief
that the number of shares of Common Stock or Common Stock Equivalents, as the
case may be, to be included in such registration would adversely affect its
ability to effect such offering, then the Company will be required to include in
such registration only that number of shares of Common Stock or Common Stock
Equivalents which it is so advised should be included in such offering. Shares
of Common Stock or Common Stock Equivalents proposed by the Company to be
registered for issuance by the Company shall have the first priority in a
registration pursuant to Section 4.2(a) and all other shares of Common 

   42
                                                                              26


Stock or Common Stock Equivalents to be registered (whether or not requested to
be registered pursuant to Section 4.1(a) or 4.2(a) or otherwise) shall be given
second priority without preference among the relevant holders. If less than all
of the Stockholder's shares of Common Stock or Common Stock Equivalents are to
be registered, each such Stockholder's shares of Common Stock or Common Stock
Equivalents shall be included in the registration pro rata based on the total
number of shares of Common Stock or Common Stock Equivalents sought to be
registered by each Stockholder (as opposed to the Company).

            (c) Custody Agreement and Power of Attorney. Upon delivering a
request under this Section 4.2, Management Investors and their Permitted
Transferees will, if requested by the Company, execute and deliver a custody
agreement and power of attorney in form and substance reasonably satisfactory to
the Company and one of the director designees referred to in Section 2.1(a)(i)
with respect to such Stockholder's shares of Common Stock or Common Stock
Equivalents to be registered pursuant to this Section 4.2 (a "Custody Agreement
and Power of Attorney"). The Custody Agreement and Power of Attorney will
provide, among other things, that the Stockholder will deliver to and deposit in
custody with the custodian and attorney-in-fact named therein (who shall be
reasonably satisfactory to one of the director designees referred to in Section
2.1(a)(i)) a certificate or certificates representing such shares of Common
Stock or Common Stock Equivalents (duly endorsed in blank by the registered
owner or owners thereof or accompanied by duly executed stock powers in blank)
and irrevocably appoint said custodian and attorney-in-fact as such
Stockholder's agent and attorney-in-fact with full power and authority to act
under the Custody Agreement and Power of Attorney on such Stockholder's behalf
with respect to the matters specified therein. Such Stockholder also agrees to
execute such other agreements as the Company may reasonably request to further
evidence the provisions of this Section 4.2.

            4.3 Registration Procedures. In connection with the Company's
obligations pursuant to Sections 4.1 and 4.2 hereof, the Company will use all
reasonable efforts to effect such registration and the Company will promptly:

            (a) prepare and file with the SEC as soon as practicable after
request for registration hereunder the requisite registration statement to
effect such registration and use all reasonable efforts to cause such
registration statement to become effective and to remain continuously effective
until the earlier to occur of (i) 180 days following the date on which such
registration statement is declared effective or (ii) the termination of the
offering being made thereunder;

            (b) prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be necessary to keep such registration statement effective and to comply
with the provisions of the Securities Act with respect to the disposition of all
shares of Common Stock or Common Stock Equivalents, as the case may be, covered
by such registration statement until such Common Stock or Common Stock
Equivalents have been sold or such lesser period of time as the Company, any
seller of such Common Stock or Common Stock Equivalents or any underwriter is
required under the Securities Act to deliver a prospectus in accordance with the
intended methods of disposition by the sellers 

   43
                                                                              27


of such Common Stock or Common Stock Equivalents set forth in such registration
statement or supplement to such prospectus;

            (c) furnish to each Stockholder which owns shares of Common Stock or
Common Stock Equivalents, as the case may be, covered by such registration
statement (the "Selling Stockholders") and the managing underwriter, if any, at
least one executed original of the registration statement and such number of
conformed copies of such registration statement and of each such amendment and
supplement thereto (in each case including all exhibits), such number of copies
of the prospectus contained in such registration statement (including each
preliminary prospectus and any summary prospectus) and any other prospectus
filed under Rule 424 under the Securities Act, as may reasonably be requested by
such Selling Stockholder;

            (d) use all reasonable efforts (i) to register or qualify all shares
of Common Stock or Common Stock Equivalents covered by such registration
statement under the securities or "blue sky" laws of such jurisdictions where an
exemption is not available as the Selling Stockholders shall reasonably request,
(ii) to keep such registration or qualification in effect for so long as such
registration statement remains in effect and (iii) to take any other action
which may be reasonably necessary or advisable to enable the Selling
Stockholders to consummate the disposition in such jurisdictions of such Common
Stock or Common Stock Equivalents; provided that the Company will not be
required to qualify generally to do business in any jurisdiction where it is not
then so qualified, subject itself to taxation in any such jurisdiction or take
any action which would subject it to general service of process in any such
jurisdiction;

            (e) notify the Selling Stockholders and the managing underwriter, if
any, promptly, and confirm such advice in writing (i) when a prospectus or any
prospectus supplement or post-effective amendment has been filed and, with
respect to a registration statement or any post-effective amendment, when the
same has become effective, (ii) of any request by the SEC for amendments or
supplements to a registration statement or related prospectus or for additional
information, (iii) of the issuance by the SEC of any stop order suspending the
effectiveness of a registration statement or the initiation of any proceedings
for that purpose, (iv) of the receipt by the Company of any notification with
respect to the suspension of the qualification of any of the registered
securities for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose, (v) of the happening of any event or information
becoming known which requires the making of any changes in a registration
statement or related prospectus so that such documents will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading
and (vi) of the Company's reasonable determination that a post-effective
amendment to a registration statement would be appropriate;

            (f) make every reasonable effort to obtain the withdrawal of any
order suspending the effectiveness of a registration statement, or the lifting
of any suspension of the qualification of any of the registered securities for
sale in any jurisdiction, at the earliest possible moment;

            (g) upon the occurrence of any event contemplated by clause (e)(v)
above, prepare a supplement or post-effective amendment to the applicable
registration statement or related prospectus or any document incorporated
therein by reference or file any other required document 

   44
                                                                              28


so that, as thereafter delivered to the purchasers of the securities being sold
thereunder, such prospectus will not contain any untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein
not misleading;

            (h) use its best efforts to furnish to the Selling Stockholders a
signed counterpart, addressed to the Selling Stockholders and the underwriters,
if any, of (A) an opinion of counsel for the Company, and (B) a "comfort"
letter, signed by the independent public accountants who have certified the
Company's financial statements included or incorporated by reference in such
registration statement, covering substantially the same matters with respect to
such registration statement (and the prospectus included therein) and, in the
case of the accountant's letter, with respect to events subsequent to the date
of such financial statements, as are customarily covered in opinions of issuer's
counsel and in accountants' letters delivered to underwriters in underwritten
public offerings of securities (and dated the dates such opinions and comfort
letters are customarily dated) and, in the case of the accountant's letter, such
other financial matters, and in the case of the legal opinion, such other legal
matters, as the Selling Stockholders or the underwriters may reasonably request;

            (i) otherwise use its best efforts to comply with all applicable
rules and regulations of the SEC, and make available to the Selling Stockholders
an earnings statement satisfying the provisions of Section 10(a)(i) of the
Securities Act and Rule 158 promulgated thereunder, no later than 90 days after
the end of any 12-month period beginning after the effective date of a
registration statement pursuant to which shares of Common Stock or Common Stock
Equivalents are sold, which statement shall cover such 12-month period;

            (j) cooperate with the Selling Stockholders and the managing
underwriters, if any, to facilitate the timely preparation and delivery of
certificates representing shares of Common Stock or Common Stock Equivalents to
be sold; and enable such shares of Common Stock or Common Stock Equivalents to
be in such denominations and registered in such names as the Selling
Stockholders or the managing underwriters, if any, may request at least two
Business Days prior to any sale of shares of Common Stock or Common Stock
Equivalents to the underwriters;

            (k) use its best efforts to cause the shares of Common Stock or
Common Stock Equivalents, as the case may be, covered by the applicable
registration statement to be registered with or approved by such other
governmental agencies or authorities as may be necessary to enable the Selling
Stockholder(s) or the underwriters, if any, to consummate the disposition of
such shares of Common Stock or Common Stock Equivalents;

            (l) cause all shares or units of Common Stock or Common Stock
Equivalents, as the case may be, covered by the registration statement to be
listed on each securities exchange, if any, on which securities of such class,
series and form issued by the Company, if any, are then listed if requested by
the managing underwriters, if any, or the holders of a majority of the shares or
units of Common Stock or Common Stock Equivalents covered by the registration
statement and entitled hereunder to be so listed;

   45
                                                                              29


            (m) cooperate and assist in any filings required to be made with the
NASD and in the performance of any due diligence investigation by any
underwriter (including any "qualified independent underwriter" that is required
to be retained in accordance with the rules and regulations of the NASD); and

            (n) as soon as practicable prior to the filing of any document which
is to be incorporated by reference into the registration statement or the
prospectus (after initial filing of the registration statement) provide copies
of such document to counsel to the Selling Stockholders and to the managing
underwriters, if any, and make the Company's representatives available for
discussion of such document and consider in good faith making such changes in
such document prior to the filing thereof as counsel for such Selling
Stockholders or underwriters may reasonably request.

            The Company may require each Selling Stockholder to furnish to the
Company such information regarding such Selling Stockholder and the distribution
of such securities as the Company may from time to time reasonably request in
writing in order to comply with the Securities Act.

            The Selling Stockholders agree that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section
4.3(e)(ii), (iii), (iv), (v) or (vi) hereof, they will forthwith discontinue
disposition pursuant to such registration statement of any shares of Common
Stock or Common Stock Equivalents, as the case may be, covered by such
registration statement or prospectus until their receipt of the copies of the
supplemented or amended prospectus relating to such registration statement or
prospectus or until they are advised in writing by the Company that the use of
the applicable prospectus may be resumed (and the period of such discontinuance
shall be excluded from the calculation of the period specified in clause (x) of
Section 4.3(a)) and, if so directed by the Company, will deliver to the Company
(at the Company's expense, except as otherwise provided in Section 4.1(d)) all
copies, other than permanent file copies then in their possession, of the
prospectus covering such securities in effect at the time of receipt of such
notice. The Selling Stockholders agree to furnish the Company a signed
counterpart, addressed to the Company and the underwriters, if any, of an
opinion of counsel for the Selling Stockholders covering substantially the same
matters with respect to such registration statement (and the prospectus included
therein) as are customarily covered in opinions of selling stockholder's counsel
delivered to the underwriters in underwritten public offerings of securities
(and dated the dates such opinions are customarily dated) and such other legal
matters as the Company or the underwriters may reasonably request.

            4.4 Underwritten Offerings.

            (a) Demand Underwritten Offerings. In any underwritten offering
pursuant to a registration requested under Section 4.1, the Company will use its
best efforts to enter into an underwriting agreement for such offering with the
underwriters selected by the Requesting Stockholder, such agreement and
underwriters to be reasonably satisfactory in form and substance to the Company,
the Requesting Stockholder and the underwriters and to contain such
representations and warranties by the Company and such other terms as are
generally prevailing in agreements of that type. The Selling Stockholders who
hold shares of Common Stock to be 

   46
                                                                              30


distributed by such underwriters shall be parties to such underwriting agreement
and may, at their option, require that any or all of the representations and
warranties by, and the other agreements on the part of, the Company to and for
the benefit of such underwriters shall also be made to and for the benefit of
them and that any or all of the conditions precedent to the obligations of such
underwriters under such underwriting agreement be conditions precedent to their
obligations. The Company may require that any or all of the representations and
warranties by, and the other agreements on the part of the Selling Stockholders
to and for the benefit of such underwriters shall also be made to and for the
benefit of the Company with due regard to the amount of Securities being sold by
such Selling Stockholder and the nature of such representations, warranties and
agreements and the underwriting.

            (b) Incidental Underwritten Offerings. If the Company at any time
proposes to register any shares of its Common Stock or Common Stock Equivalents
under the Securities Act as contemplated by Section 4.2 and such Securities are
to be distributed by or through one or more underwriters, the Company and the
Selling Stockholders who hold shares of Common Stock or Common Stock Equivalents
to be distributed by such underwriters in accordance with Section 4.2 hereof
shall be parties to the underwriting agreement between the Company and such
underwriters and may, at their option, require that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such underwriters shall also be made to and
for the benefit of them and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be conditions
precedent to their obligations. The Company may, at its option, require that any
or all of the representations and warranties by, and the other agreements on the
part of the Selling Stockholders to and for the benefit of such underwriters
shall also be made to and for the benefit of the Company with due regard to the
amount of Securities being sold by such Selling Stockholder and the nature of
such representations, warranties and agreements and the underwriting.

            4.5 Preparation; Reasonable Investigation. In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the Selling Stockholders, the
underwriters and their respective counsels and accountants a reasonable
opportunity (but such Persons shall not have the obligation) to participate in
the preparation of such registration statement, each prospectus included therein
or filed with the SEC, and, to the extent practicable, each amendment thereof or
supplement thereto, and, subject to the execution and delivery of a customary
confidentiality agreement, will give each of them such access to its books and
records (to the extent customarily given to the underwriters of the Company's
securities), and such opportunities to discuss the business of the Company with
its officers and the independent public accountants who have certified its
financial statements as shall be necessary to conduct a reasonable investigation
within the meaning of the Securities Act.

            4.6 Limitations, Conditions and Qualifications to Obligations under
Registration Covenants. The obligations of the Company to use its reasonable
efforts to cause shares of Common Stock and Common Stock Equivalents to be
registered under the Securities Act are subject to each of the following
limitations, conditions and qualifications:

   47
                                                                              31


            (a) The Company shall be entitled to postpone for a reasonable
period of time the filing or effectiveness of, or suspend the rights of Selling
Stockholders to make sales pursuant to, any registration statement otherwise
required to be prepared, filed and made and kept effective by it hereunder (but
the duration of such postponement or suspension may not exceed the earlier to
occur of (i) 15 days after the cessation of the circumstances described in
clauses (A) and (B) below or (ii) 120 days after the date of the determination
of the Board of Directors of the Company referred to below, and the duration of
such postponement or suspension shall be excluded from the calculation of the
period specified in clause (i) of Section 4.3(a)) if the Board of Directors of
the Company determines in good faith that (A) there is a material undisclosed
development in the business or affairs of the Company (including any pending or
proposed financing, recapitalization, acquisition or disposition), the
disclosure of which at such time could be adverse to the Company's interests or
(B) the Company has filed a registration statement with the SEC, such
registration statement has not yet been declared effective, the Company is using
its reasonable best efforts to have such registration statement declared
effective, and the underwriters with respect to such registration advise that
such registration would be adversely affected. If the Company shall so delay the
filing of a registration statement, it shall, as promptly as possible, notify
the Selling Stockholders of such determination, and the Selling Stockholders
shall have the right (x) in the case of a postponement of the filing or
effectiveness of a registration statement, to withdraw the request for
registration by giving written notice to the Company within 10 days after
receipt of the Company's notice or (y) in the case of a suspension of the right
to make sales, to receive an extension of the registration period equal to the
number of days of the suspension.

            (b) The Company shall not be required hereby to include shares of
Common Stock or Common Stock Equivalents in a registration statement if, in the
written opinion (to be issued to, and relied upon by, the Stockholders seeking
inclusion) of outside counsel to the Company of recognized standing in
securities law matters, the beneficial owners of such Common Stock or Common
Stock Equivalents seeking registration would be free to sell all of such shares
of Common Stock or Common Stock Equivalents within the current calendar quarter
without registration under Rule 144 under the Securities Act.

            (c) The Company's obligations shall be subject to the obligations of
the Selling Stockholders, which the Selling Stockholders acknowledge, to furnish
all information and materials and to take any and all actions as may be required
under applicable federal and state securities laws and regulations to permit the
Company to comply with all applicable requirements of the SEC and to obtain any
acceleration of the effective date of such registration statement.

            (d) The Company shall not be obligated to cause any special audit to
be undertaken in connection with any registration pursuant hereto unless such
audit is requested by the underwriters with respect to such registration.

            4.7 Expenses. The Company and Sheridan jointly and severally agree
to pay all reasonable out-of-pocket costs and expenses incurred in connection
with each registration of Common Stock or Common Stock Equivalents pursuant to
this Agreement, including, without limitation, the reasonable fees and
disbursements of a single firm of outside counsel retained by Selling
Stockholders which beneficially own a majority of the total number of shares or
units of Common Stock or Common Stock Equivalents being registered by Selling
Stockholders (the

   48
                                                                              32


"Majority Selling Stockholders"), and any and all filing fees payable to the
SEC, fees with respect to filings required to be made with stock exchanges, the
NASDAQ and the NASD, fees and expenses of compliance with state securities or
blue sky laws (including reasonable fees and disbursements of a single firm of
outside counsel for the underwriters or the Majority Selling Stockholders in
connection with blue sky qualifications of the Common Stock or Common Stock
Equivalents being registered and determination of its eligibility for investment
under the laws of such jurisdictions as the Selling Stockholders may designate),
printing expenses, fees and disbursements of counsel and accountants of the
Company, including costs associated with comfort letters, and fees and expenses
of other Persons retained by the Company, but excluding underwriters' expenses
(including discounts, commissions or fees of underwriters and expenses included
therein, selling brokers, dealer managers or similar securities industry
professionals relating to the distribution of the securities being registered or
legal expenses of any Person other than the Company and the Selling
Stockholders) but including the fees and expenses of any qualified independent
underwriter required to participate in such registration pursuant to applicable
law or the requirements of the NASD. The Company and its Subsidiaries shall, in
any event in all cases, pay its internal expenses (including, without
limitation, all salaries and expenses of its officers and employees performing
legal or accounting duties), and the expense of securities law liability
insurance and rating agency fees, if any.

            4.8 Indemnification.

            (a) Indemnification by the Company. In connection with any
registration pursuant hereto in which shares of Common Stock or Common Stock
Equivalents are to be disposed of, the Company shall indemnify and hold
harmless, to the full extent permitted by law, each holder of such Common Stock
or Common Stock Equivalents to be disposed of and, when applicable, its
officers, directors, agents and employees and each Person who controls such
holder (within the meaning of the Securities Act or the Exchange Act) against
all losses, claims, damages, liabilities and expenses caused by any untrue or
alleged untrue statement of a material fact contained in any registration
statement, prospectus or preliminary prospectus or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, including, without
limitation, any loss, claim, damage, liability or expense resulting from the
failure to keep a prospectus current, except insofar as the same (i) are caused
by or contained in any information relating to such holder furnished in writing
to the Company by such holder expressly for use therein or (ii) are caused by
such holder's failure to deliver a copy of the current prospectus simultaneously
with or prior to such sale after the Company has furnished such holder with a
sufficient number of copies of such prospectus correcting such material
misstatement or omission or (iii) arise in respect of any offers to sell or
sales made during any period when a holder is required to discontinue sales
under Section 4.3(e) (and after such holder has received in writing the notice
contemplated by Section 4.3(e)). The Company shall also indemnify underwriters,
selling brokers, dealer managers and similar securities industry professionals
participating in the distribution, their officers and directors and each person
who controls such Persons (within the meaning of the Securities Act) to the same
extent as provided above with respect to the indemnification of the holders of
such Common Stock or Common Stock Equivalents to be disposed of, and shall enter
into an indemnification agreement with such Persons containing such terms, if
requested.

   49
                                                                              33


            (b) Indemnification by Stockholders. In connection with each
registration statement effected pursuant hereto in which shares of Common Stock
or Common Stock Equivalents are to be disposed of, each Selling Stockholder
shall, severally but not jointly, indemnify and hold harmless, to the full
extent permitted by law, the Company, each other Selling Stockholder and their
respective directors, officers, agents and employees and each Person who
controls the Company and each other Selling Stockholder (within the meaning of
the Securities Act or the Exchange Act) against any losses, claims, damages,
liabilities and expenses resulting from any untrue statement of a material fact
or any omission of a material fact required to be stated in such registration
statement or prospectus or preliminary prospectus or necessary to make the
statements therein not misleading, to the extent, but only to the extent, that
such untrue statement or omission relates to such Selling Stockholder and is
contained in any information furnished in writing by such Selling Stockholder or
any of its Affiliates to the Company expressly for inclusion in such
registration statement or prospectus. In no event shall the liability of any
Selling Stockholder hereunder be greater in amount than the dollar amount of the
proceeds actually received by such Selling Stockholder upon the sale of the
securities giving rise to such indemnification obligation.

            (c) Conduct of Indemnification Proceedings. Any Person entitled to
indemnification hereunder shall give prompt notice to the indemnifying party of
any claim with respect to which it shall seek indemnification and shall permit
such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party; provided, however, that any
Person entitled to indemnification hereunder shall have the right to employ
separate counsel and to participate in the defense of such claim, but the fees
and expenses of such counsel shall be at the expense of such Person unless (i)
the indemnifying party shall have agreed to pay such fees or expenses, or (ii)
the indemnifying party shall have failed to assume the defense of such claim and
employ counsel reasonably satisfactory to such Person or (iii) in the opinion of
outside counsel to such Person there may be one or more legal defenses available
to such Person which are different from or in addition to those available to the
indemnifying party with respect to such claims (in which case, if the Person
notifies the indemnifying party in writing that such Person elects to employ
separate counsel at the expense of the indemnifying party, the indemnifying
party shall not have the right to assume the defense of such claim on behalf of
such Person). If such defense is not assumed by the indemnifying party, the
indemnifying party shall not be subject to any liability for any settlement made
without its consent (but such consent shall not be unreasonably withheld). No
indemnified party shall be required to consent to entry of any judgment or enter
into any settlement that does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such indemnified party of a written
release in form and substance reasonably satisfactory to such indemnified party
from all liability in respect of such claim or litigation. An indemnifying party
who is not entitled to, or elects not to, assume the defense of a claim shall
not be obligated to pay the fees and expenses of more than one firm of counsel
(and, if necessary, local counsel) for all parties indemnified by such
indemnifying party with respect to such claim, unless in the written opinion of
outside counsel to an indemnified party a conflict of interest as to the subject
matter exists between such indemnified party and another indemnified party with
respect to such claim, in which event the indemnifying party shall be obligated
to pay the fees and expenses of additional counsel for such indemnified party.

   50
                                                                              34


            (d) Contribution. If for any reason the indemnification provided for
herein is unavailable to an indemnified party or is insufficient to hold it
harmless as contemplated hereby, then the indemnifying party shall contribute to
the amount paid or payable by the indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect not
only the relative benefits received by the indemnified party and the
indemnifying party, but also the relative fault of the indemnified party and the
indemnifying party, as well as any other relevant equitable considerations,
provided that in no event shall the liability of any Selling Stockholder for
such contribution and indemnification exceed, in the aggregate, the dollar
amount of the proceeds received by such Selling Stockholder upon the sale of
securities giving rise to such indemnification and contribution obligation.

            4.9 Participation in Underwritten Registrations. No Stockholder or
Permitted Transferee may participate in any underwritten registration hereunder
unless such Stockholder or Permitted Transferee (a) agrees to sell its shares of
Common Stock or Common Stock Equivalents on the basis provided in and in
compliance with any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and to comply with Rules 10b-6 and 10b-7
under the Exchange Act, and (b) completes and executes all questionnaires,
appropriate and limited powers of attorney, escrow agreements, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements; provided that all such documents shall be
consistent with the provisions hereof.

            4.10 Rule 144. The Company hereby covenants that after it has filed
(and such registration statement has become effective) a registration statement
pursuant to the requirements of Section 12 of the Exchange Act or a registration
statement pursuant to the requirements of the Securities Act in respect of
Common Stock, the Company will file in a timely manner all reports required to
be filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder (or, if the Company is not required to
file such reports, it will, upon the request of any Stockholder, make publicly
available other information so long as necessary to permit sales by such
Stockholder under Rule 144 under the Securities Act) and will take such further
action as any Stockholder may reasonably request to the extent required from
time to time to enable such Stockholder to sell shares of Common Stock under
Rule 144 under the Securities Act. Notwithstanding the foregoing, no Management
Investor shall Transfer shares of Common Stock under Rule 144 unless expressly
permitted to do so by the terms of this Agreement.

            4.11 Holdback Agreements. (a) Each Stockholder agrees that, if any
of its shares of Common Stock or Common Stock Equivalents is included in a
registration statement filed by the Company in connection with an underwritten
public offering it shall not effect any public sale or distribution of shares of
Common Stock or Common Stock Equivalents during the 30 days prior to or the 180
day period beginning on the effective date of such registration statement
(except as part of such registration) if and to the extent reasonably requested
in writing (with reasonable prior notice) by the managing underwriter of the
underwritten public offering.

            (b) The Company agrees not to effect any primary public sale or
distribution of any Common Stock or Common Stock Equivalents, as the case may
be, during the 10 days prior to and the 180 day period beginning on the
effective date of any registration statement in which

   51
                                                                              35


any Stockholder is participating in connection with an underwritten public
offering of Common Stock or Common Stock Equivalents, as the case may be, if and
to the extent reasonably requested in writing (with reasonable prior notice) by
the managing underwriter of the underwritten public offering.

            4.12 Mezzanine Securities. Notwithstanding anything to the contrary
herein, the Company may grant registration rights to holders of Mezzanine
Securities which are more, as or less favorable to such holders than the
registration rights of the parties hereto. To the extent that Mezzanine
Securities consist of Common Stock or Common Stock Equivalents, holders of
Mezzanine Securities may be given the right by the Company to participate in
registrations as if such holders were Stockholders, and the Company shall not be
obliged hereunder to comply with any provision of this Section 4 in respect of a
registration of Mezzanine Securities.

            SECTION 5. MISCELLANEOUS

            5.1 Additional Securities Subject to Agreement. Each Stockholder
agrees that any other Securities which it shall hereafter acquire by means of a
stock split, stock dividend, distribution, exercise of stock options, or
otherwise (other than Mezzanine Securities or pursuant to a Public Offering or
Section 3.2(a)(iii)) shall be subject to the provisions of this Agreement to the
same extent as if held on the date hereof.

            5.2 Termination. Except as otherwise provided herein, this Agreement
shall terminate, and thereby become null and void, as to any particular
Securities, on the date on which they are sold in a Public Offering or are sold
pursuant to Rule 144 under the Securities Act (unless such Securities are
reacquired by a Stockholder).

            5.3 Injunctive Relief. The Stockholders and their Permitted
Transferees acknowledge and agree that a violation of any of the terms of this
Agreement will cause the Stockholders and their Permitted Transferees
irreparable injury for which adequate remedy at law is not available.
Accordingly, it is agreed that each Stockholder and Permitted Transferee shall
be entitled to an injunction, restraining order or other equitable relief to
prevent breaches of the provisions of this Agreement and to enforce specifically
the terms and provisions hereof in any court of competent jurisdiction in the
United States or any state thereof, in addition to any other remedy to which
they may be entitled at law or equity.

            5.4 Other Stockholders' Agreements. None of the Stockholders shall
enter into any stockholder agreement or other arrangement of any kind with any
Person with respect to any Securities which is inconsistent with the provisions
of this Agreement or which may impair its ability to comply with this Agreement.

instrument signed (a) by Vestar, so long as it or its Affiliates own Securities,
and (b) by Stockholders other than Vestar and its Affiliates which own on a
fully diluted basis Securities representing at least a majority of the voting

                                                                              36

which Permitted Transferees shall agree, in a writing in form and substance
satisfactory to the Company and the owners on a fully diluted basis of
Securities representing at least a majority of the voting power represented by
all Securities outstanding on a fully diluted basis and owned by all
Stockholders, to become a party hereto and be bound to the same extent as its
transferor hereby, provided that no Stockholder may assign to any Permitted
Transferee any of its rights hereunder other than in connection with a Transfer
to such Permitted Transferee of Securities in accordance with the provisions of
this Agreement.

acts as are required, authorized or contemplated by this Agreement to 

   54
                                                                              38

Investor Representative shall be the only Person authorized to take any action
so required, authorized or contemplated by this Agreement by each such Person.
Each such Person further acknowledges that the foregoing appointment and
designation shall be deemed to be coupled with an interest and shall survive the

Permitted Transferee shall be deemed to have authorized) the other parties
hereto to disregard any notice or other action taken by such Person pursuant to
this Agreement on any action so taken or any notice given by the Management
Investor Representative and are and will be entitled and authorized to give
notices only to the Management Investor Representative for any notice
contemplated by this Agreement to be given to any such Person. A successor to
the Management Investor Representative may be chosen by Management Investors
which own on a fully diluted basis Securities representing at least a majority
of the voting power represented by all Securities outstanding on a fully diluted
basis and owned by all Management Investors, provided that written notice
thereof is given by the successor to the Management Investor Representative to

required to be taken or given by the Management Investors, the action or consent
of the Management Investor Representative shall be considered the act or consent
of all the Management Investors, and Vestar and the Company shall be protected
in relying on such act or consent.

            5.16 Covenant Not to Compete. (a) Each Management Investor who is
not a Senior Management Investor and who is not a party to a written employment
agreement with the Company or any of its Subsidiaries that contains a
non-competition provision hereby covenants and agrees that, except as provided
below, during the Term of Employment and the Non-Competition Period, the
Management Investor shall not, without the express written consent of the
Company, directly or indirectly, engage in any activity which is, or participate
or invest in or assist (whether as owner, part-owner, stockholder, partner,
director, officer, trustee, employee, agent, independent contractor or
consultant, or in any other capacity) any Competitive Enterprise, except that
the Management Investor may make passive investments in a Competitive Enterprise
the shares of which are publicly traded if such investment constitutes less than
one percent of the equity of such enterprise. Without implied limitation, the
forgoing covenant shall include hiring or attempting to hire for or on behalf of
any such Competitive Enterprise any officer or other employee of Sheridan or any
Affiliate of Sheridan, encouraging any officer, Health Care Provider or employee
to terminate his or her relationship or employment with Sheridan or any
Affiliate of Sheridan, soliciting for or on behalf of any such Competitive
Enterprise any client or customer (including any Medical Customer) of Sheridan
or any Affiliate of Sheridan, and diverting to any Person, any client or
business opportunity of Sheridan or any Affiliate of Sheridan.

            (b) In furtherance and not in limitation of the foregoing
restrictions, during the Term of Employment and the Non-Competition Period, each
Management Investor who is not a Senior Management Investor and who is not a
party to a written employment agreement with the Company or any of its
Subsidiaries that contains a non-competition provision shall not devote any time
to consulting, lecturing or engaging in other self-employment or employment
activities without the prior written consent of Sheridan.

            (c) This Section 5.16 shall survive the termination of this
Agreement.

   55
                                                                              39


            5.17 Business Opportunities. Each Management Investor who is not a
Senior Management Investor and who is not a party to a written employment
agreement with the Company or any of its Subsidiaries that contains a business
opportunities provision agrees, while he is employed by any of the Company and
its Subsidiaries, to offer or otherwise make known or available to the Company
or any Subsidiary, as directed by the Company and without additional
compensation or consideration, any business prospects, contracts or other
business opportunities that he may discover, find, develop or otherwise have
available to him in any field in which the Company or any of its Affiliates is
engaged, and further agrees that any such prospects, contracts or other business
opportunities shall be the property of the Company.

            5.18 Confidentiality. (a) Each Management Investor who is not a
Senior Management Investor and who is not a party to a written employment
agreement with the Company or any of its Subsidiaries that contains a
confidentiality provision acknowledges that the Management Investor has and will
necessarily become informed of, and have access to, certain valuable and
confidential information of the Company and its Affiliates, including, without
limitation, trade secrets, technical information, plans, lists of patients,
data, records, fee schedules, computer programs, manuals, processes, methods,
intangible rights, contracts, agreements, licenses, personnel information and
the identity of health care providers (collectively, the "Confidential
Information"), and that the Confidential Information, even though it may be
contributed, developed or acquired in whole or in part by the Management
Investor, is the Company's exclusive property to be held by the Management
Investor in trust and solely for the Company's benefit. Accordingly, except as
required by law, the Management Investor shall not, at any time, either during
or subsequent to the Term of Employment, use, reveal, report, publish, copy,
transcribe, Transfer or otherwise disclose to any person, corporation or other
entity, any of the Confidential Information without the prior written consent of
the Company, except to responsible officers and employees of the Company and its
Subsidiaries and other responsible persons who are in a contractual or fiduciary
relationship with the Company or one of its Subsidiaries and except for
information which legally and legitimately is or becomes of general public
knowledge from authorized sources other than the Management Investor.

            (b) Upon the termination of the Term of Employment, each Management
Investor who is not a Senior Management Investor and who is not a party to a
written employment agreement with the Company or any of its Subsidiaries that
contains a confidentiality provision shall promptly deliver to the Company all
property and possessions of the Company and its Subsidiaries, including all
drawings, manuals, letters, notes, notebooks, reports, copies, deliverable
Confidential Information and all other materials relating to the Company's and
its Subsidiaries' business which are in the Management Investor's possession or
control.

            5.19 Effectiveness. This Agreement shall become effective on the
Closing Date.

   62
                                                                               4

      SECTION 4. Shares Available for Options.

      (a) Shares Available. Subject to adjustment as provided in Section 4(b),
the aggregate number of Shares with respect to which Options may be granted
under the Plan shall be 1,150,000; provided, however, that in no event shall the
number of Shares subject to Time Options granted under the Plan exceed 666,667.
If, after the effective date of the Plan, any Shares covered by an Option
granted under the Plan, or to which such an Option relates, are forfeited, or if
an Option has expired, terminated or been cancelled for any reason whatsoever
(other than by reason of exercise or vesting), then the Shares covered by such
Option shall again be, or shall become, Shares with respect to which Options may
be granted hereunder.

      (b) Adjustments. In the event that the Committee determines that any Exit
Transaction, dividend or other distribution (whether in the form of cash,
Shares, other securities, or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company, or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee in its
discretion to be necessary or appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan, then the Committee shall, in such manner as it in good faith
deems equitable, adjust any or all of (i) the number of Shares or other
securities of the Company (or number and kind of other securities or property)
with respect to which Options may be granted, (ii) the number of Shares or other
securities of the Company (or number and kind of other securities or property)
subject to outstanding Options, and (iii) the exercise price with respect to any
Option or, if deemed appropriate in connection with a Change of Control, make
provision for an immediate cash payment to the holder of an outstanding Option
in consideration for the cancellation of such Option in an amount equal to the
excess, if any, of the Fair Market Value of the Shares subject to the Options
over the aggregate exercise price of such Option.

      (c) Substitute Options. Options may be granted, in the discretion of the
Committee, under the Plan in assumption of, or in substitution for, outstanding
awards previously granted by a company acquired by the Company or with which the
Company combines ("Substitute Options"). The number of Shares underlying any
Substitute Options shall be counted against the aggregate number of Shares
available for Options under the Plan.

      (d) Sources of Shares Deliverable Under Options. Any Shares delivered
pursuant to an Option may consist, in whole or in part, of authorized and
unissued Shares or of treasury Shares.

      SECTION 5. Eligibility. Any officer, key employee or outside director of,
or consultant to, the Company or any of its Subsidiaries (including any
prospective officer or key employee) shall be eligible to be designated a
Participant.

      (a) Grant. Subject to the provisions of the Plan, the Committee shall have
sole and complete authority to determine the Participants to whom Options shall
be granted, the


   63
                                                                               5

number of Shares to be covered by each Option, the exercise price therefor and
the conditions and limitations applicable to the exercise of the Option. None of
the Options granted under the Plan are intended to meet the requirements of
Section 422 of the Code or any successor provision thereto.

      (b) Exercise Price. The Committee shall establish the exercise price at
the time each Option is granted, which exercise price shall be set forth in the
applicable Award Agreement.

      (b) Exercise. Each Option shall be exercisable at such times and subject
to such terms and conditions as the Committee may, in its sole discretion,
specify in the applicable Award Agreement or, with the consent of the
Participant thereafter. The Committee may impose such conditions with respect to
the exercise of Options, including without limitation, any relating to the
application of federal or state securities laws, as it may deem necessary or
advisable.

      (c) Payment. No Shares shall be delivered pursuant to any exercise of an
Option until payment in full of the aggregate exercise price therefor is
received by the Company. Such payment shall be made in cash or by bank check or,
subject to the consent of the Committee in its sole discretion, in Shares which
have been owned by the Participant for at least six months, such Shares to be
valued at their Fair Market Value as of the date of exercise.

      SECTION 7. Amendment and Termination.

      (a) Amendments to the Plan. The Board may amend, alter, suspend,
discontinue, or terminate the Plan or any portion thereof at any time; provided
that any such amendment, alteration, suspension, discontinuance or termination
that would impair the rights of any Participant or any holder or beneficiary of
any Option theretofore granted shall not to that extent be effective without the
consent of the affected Participant, holder or beneficiary.

      (b) Amendments to Options. The Committee may waive any conditions or
rights under, amend any terms of, or alter any Option theretofore granted,
prospectively or retroactively; provided that any such waiver, amendment or
alteration that would impair the rights of any Participant or any holder or
beneficiary of any Option theretofore granted shall not to that extent be
effective without the consent of the affected Participant, holder or
beneficiary. In addition, with the consent of any Participant, holder or
beneficiary, the Company may suspend, discontinue, cancel or terminate any
Option theretofore granted, prospectively or retroactively

      (c) Adjustment of Options Upon the Occurrence of Certain Unusual or
Nonrecurring Events. The Committee is hereby authorized to make adjustments in
the performance criteria applicable to outstanding Performance Options in the
event of any extraordinary and nonrecurring events affecting the Company or its
Subsidiaries, or the financial statements of the Company or its Subsidiaries, or
of changes in applicable laws, regulations, or accounting principles, whenever
the Committee determines in good faith that such adjustments are necessary in
order to prevent dilution or enlargement of rights under such Performance
Options.

                                                                               6

      SECTION 8. Change of Control. In the event of a Change of Control after
the date of the adoption of this Plan, (i) any outstanding Time Options then
held by Participants, which are unexercisable or otherwise unvested, shall
automatically be deemed exercisable or otherwise vested, as the case may be, as
of immediately prior to such Change of Control and (ii) any outstanding
Performance Options, whether exercisable or not, then held by Participants,
shall continue to be governed by the terms of each such Participant's Award
Agreement.

      SECTION 9. General Provisions.

      (a) Nontransferability.

      (i) Each Option shall be exercisable only by the Participant during the
Participant's lifetime, or, if permissible under applicable law, by the
Participant's legal guardian or representative. No Option may be assigned,
alienated, pledged, attached, sold or otherwise transferred or encumbered by a
Participant otherwise than by will or by the laws of descent and distribution
and any such purported assignment, alienation, pledge, attachment, sale,
transfer or encumbrance shall be void and unenforceable against the Company or
any Affiliate; provided that the designation of a beneficiary shall not
constitute an assignment, alienation, pledge, attachment, sale, transfer or
encumbrance.

      (ii) Notwithstanding the foregoing, the Committee may in the applicable
Award Agreement evidencing an Option granted under the Plan or at any time
thereafter in an amendment to an Award Agreement provide that Options granted
hereunder may be transferred by the Participant to whom such Option was granted
(the "Grantee") without consideration, subject to such rules as the Committee
may adopt to preserve the purposes of the Plan, to:

            (A) the Grantee's spouse, children or grandchildren (including
      adopted and stepchildren and grandchildren) (collectively, the "Immediate
      Family");

            (B) a trust solely for the benefit of the Grantee and his or her
      Immediate Family; or

            (C) a partnership or limited liability company whose only partners
      or members are the Grantee and his or her Immediate Family members;

      (each transferee described in clauses (A), (B) and (C) above is
      hereinafter referred to as a "Permitted Transferee"); provided that the
      Grantee gives the Committee advance written notice describing the terms
      and conditions of the proposed transfer and the Committee notifies the
      Grantee in writing that such a transfer would comply with the requirements
      of the Plan and any applicable Award Agreement evidencing the Option.

      The terms of any Option transferred in accordance with the immediately
      preceding sentence shall apply to the Permitted Transferee and any
      reference in the Plan or in an Award Agreement to an optionee, Grantee or
      Participant shall be deemed to refer to the Permitted Transferee, except
      that (a) Permitted Transferees shall not be entitled to transfer any
      Options, other than by will or the laws of descent and distribution; (b)
      Permitted Transferees shall not be entitled to exercise any transferred
      Options unless


   65
                                                                               7

      there shall be in effect a registration statement on an
      appropriate form covering the Shares to be acquired pursuant to the
      exercise of such Option if the Committee determines that such a
      registration statement or form is necessary or appropriate, (c) the
      Committee or the Company shall not be required to provide any notice to a
      Permitted Transferee, provided all required notices are given to the
      Grantee and (d) the consequences of termination of the Grantee's
      employment by, or services to, the Company or any of its Affiliates under
      the terms of the Plan and the applicable Award Agreement shall continue to
      be applied with respect to the Grantee, following which the Options shall
      be exercisable by the Permitted Transferee only to the extent, and for the
      periods, specified in the Plan and the applicable Award Agreement.

      (b) No Rights to Options. No Participant or other Person shall have any
claim to be granted any Option, and there is no obligation for uniformity of
treatment of Participants, or holders or beneficiaries of Options. The terms and
conditions of Options and the Committee's determinations and interpretations
with respect thereto need not be the same with respect to each Participant
(whether or not such Participants are similarly situated).

      (c) Share Certificates. All certificates for Shares or other securities of
the Company delivered under the Plan pursuant to any Option or the exercise
thereof shall be subject to such stop transfer orders and other restrictions as
the Committee may deem advisable under the rules, regulations, and other
requirements of the SEC, any stock exchange upon which such Shares or other
securities are then listed, any applicable Federal or state laws, and any
applicable written agreements between Vestar and/or the Company and the
Participants including, without limitation, the Stockholders' Agreement, and the
Committee may cause a legend or legends to be put on any such certificates to
make appropriate reference to such restrictions.

      (d) Withholding.

            (i) A Participant shall be required to pay to the Company or any
Affiliate and the Company shall have the right and is hereby authorized to
withhold, any applicable withholding taxes in respect of an Option, its exercise
or any payment or transfer under an Option or under the Plan and to take such
other action as may be necessary in the opinion of the Company to satisfy all
obligations for the payment of such withholding taxes.

            (ii) Notwithstanding any provision of this Plan to the contrary, in
connection with the transfer of an Option to a Permitted Transferee pursuant to
Section 9(a) of the Plan, the Grantee shall remain liable for any withholding
taxes required to be withheld upon the exercise of such Option by the Permitted
Transferee.

      (e) Award Agreements. Each Option hereunder shall be evidenced by an Award
Agreement, which shall be delivered to the Participant and shall specify the
terms and conditions of the Option and any rules applicable thereto, including
but not limited to the effect on such Option of the death, disability or
termination of employment or service of a Participant, and the effect, if any,
of such other events as may be determined by the Committee.

      (f) No Limit on Other Compensation Arrangements. Nothing contained in the
Plan shall prevent the Company or any Affiliate from adopting or continuing in
effect other


   66
                                                                               8

compensation arrangements, which may, but need not, provide for the grant of
options (subject to stockholder approval if such approval is required), and such
arrangements may be either generally applicable or applicable only in specific
cases.

      (g) No Right to Employment. The grant of an Option shall not be construed
as giving a Participant the right to be retained in the employ of, or in any
consulting relationship to, the Company or any Affiliate. Further, the Company
or an Affiliate may at any time dismiss a Participant from employment or
discontinue any consulting relationship, free from any liability or any claim
under the Plan, unless otherwise expressly provided in the Plan or in any Award
Agreement.

      (h) No Rights as Stockholder. Subject to the provisions of the applicable
Option, no Participant or holder or beneficiary of any Option shall have any
rights as a stockholder with respect to any Shares to be distributed under the
Plan until he or she has become the holder of such Shares.

      (i) Governing Law. The validity, construction, and effect of the Plan and
any rules and regulations relating to the Plan and any Award Agreement shall be
determined in accordance with the laws of the State of New York.

      (j) Severability. If any provision of the Plan or any Option is or becomes
or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as
to any Person or Option, or would disqualify the Plan or any Option under any
law deemed applicable by the Committee, such provision shall be construed or
deemed amended to conform the applicable laws, or if it cannot be construed or
deemed amended without, in the determination of the Committee, materially
altering the intent of the Plan or the Option, such provision shall be stricken
as to such jurisdiction, Person or Option and the remainder of the Plan and any
such Option shall remain in full force and effect.

      (k) Other Laws. The Committee may refuse to issue or transfer any Shares
or other consideration under an Option if, acting in its sole discretion, it
determines that the issuance or transfer of such Shares or such other
consideration will violate any applicable law or regulation or entitle the
Company to recover the same under Section 16(b) of the Exchange Act, and any
payment tendered to the Company by a Participant, other holder or beneficiary in
connection with the exercise of such Option shall be promptly refunded to the
relevant Participant, holder or beneficiary. Without limiting the generality of
the foregoing, no Option granted hereunder shall be construed as an offer to
sell securities of the Company, and no such offer shall be outstanding, unless
and until the Committee in its sole discretion has determined that any such
offer, if made, would be in compliance with all applicable requirements of the
U.S. federal and any other applicable securities laws.

      (l) No Trust or Fund Created. Neither the Plan nor any Option shall create
or be construed to create a trust or separate fund of any kind or a fiduciary
relationship between the Company or any Affiliate and a Participant or any other
Person. To the extent that any Person acquires a right to receive payments from
the Company or any Affiliate pursuant to an Option, such right shall be no
greater than the right of any unsecured general creditor of the Company or any
Affiliate.

      (m) No Fractional Shares. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Option, and the Committee shall determine
whether cash, other securities, or other property shall be paid or transferred
in lieu of any fractional Shares or whether such fractional Shares or any rights
thereto shall be canceled, terminated, or otherwise eliminated.

      (n) Headings. Headings are given to the Sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.

Holdings, Inc., a Delaware corporation (hereinafter called the "Company"), and
_______ (hereinafter called the "Participant"):

                                R E C I T A L S:

      WHEREAS, the Company has adopted the Vestar/Calvary Holdings, Inc. 1999
Stock Option Plan (the "Plan"), which Plan is incorporated herein by reference
and made a part of this Agreement. Capitalized terms not otherwise defined
herein shall have the same meanings as in the Plan; and

      WHEREAS, the Committee has determined that it would be in the best
interests of the Company and its stockholders to grant the option provided for
herein (the "Option") to the Participant pursuant to the Plan and the terms set
forth herein.

      NOW THEREFORE, in consideration of the mutual covenants hereinafter set
forth, the parties agree as follows:

      1. Grant of the Option. The Company hereby grants to the Participant the
right and option (the "Option") to purchase, on the terms and conditions
hereinafter set forth, all or any part of an aggregate of ______ Shares, subject
to adjustment as set forth in the Plan. The purchase price of the Shares subject

Healthcare, Inc. ("Sheridan") in the Offer referred to in the Agreement and Plan
of Merger dated March 24 , 1999 among the Company, Sheridan and Vestar/Calvary,
Inc. The Option is intended to be a non-qualified stock option, and is not
intended to be treated as an option that complies with Section 422 of the
Internal Revenue Code of 1986, as amended.

      2. Vesting. At any time, the portion of the Option which has become vested
and exercisable as described in this Section 2 is hereinafter referred to as the

(1)The Date of Grant will be the Effective Time under the Merger Agreement.

                                                                               2

      (a) Time Vesting.

      Subject to paragraphs (b), (c) and (d) of this Section 2, the Option
shall vest and become exercisable in full on the ninth anniversary of the
purchase of shares of common stock of Sheridan pursuant to the Offer (the date
of such purchase being the "Purchase Date").

      (b) Accelerated Vesting Based Upon Performance.

            (i) Subject to the Participant's continued employment with the
Company, the Option shall vest and become exercisable on an accelerated basis
with respect to up to twenty-five percent (25%) of the Shares initially covered
by the Option (such 25% being referred to as the "Scheduled Accelerated Vesting
Shares") on each of the first, second, third and fourth anniversaries of the
Purchase Date (each an "Accelerated Vesting Date") as follows:

                  (A) With respect to each Accelerated Vesting Date, 100% of
the Scheduled Accelerated Vesting Shares will vest if the Value of Common Equity
Per Share (as defined in Exhibit A) as of the last day of the fiscal year ending
immediately prior to the applicable Accelerated Vesting Date (such last day of
the fiscal year being referred to as the "Determination Date") equals or exceeds
the Maximum Annual Price Target (described below) for such Determination Date;

                  (B) With respect to each Accelerated Vesting Date, 0% of the
Scheduled Accelerated Vesting Shares will vest if the Value of Common Equity Per
Share as of the applicable Determination Date is less than or equal to the
Minimum Annual Price Target (described below) for such Determination Date; and

                  (C) With respect to each Accelerated Vesting Date, if the
Common Equity Per Share as of the Determination Date is less than the Maximum
Annual Price Target and greater than the Minimum Annual Price Target for such
Determination Date, then the number of Scheduled Accelerated Vesting Shares
which shall vest will equal the product of (x) 100% of the Scheduled Accelerated
Vesting Shares times (y) the Proration Fraction. The Proration Fraction shall
equal the quotient obtained by dividing (A) the excess of the Value of Common
Equity Per Share as of the Determination Date over the Minimum Annual Price
Target for such Determination Date by (B) the excess of the Maximum Annual Price
Target as of the Determination Date over the Minimum Annual Price Target for
such Determination Date.

            (ii) In the event that the Option does not vest on an accelerated
basis with respect to all of the Scheduled Accelerated Vesting Shares on an
Accelerated Vesting Date solely as a result of the failure to achieve or exceed
the applicable Maximum Annual Price Target, then the number of Scheduled Vesting
Shares with respect to which the Option did not vest on an accelerated basis
(the "Missed Shares"), will be available for vesting on the next succeeding
Accelerated Vesting Date only (the "Make-Up Vesting Date") as follows: The
number of Missed Shares, if any, which will vest on an accelerated basis on the
Make-Up Vesting Date will equal the excess, if any, of (x) the number of
Scheduled Accelerated Vesting Shares which vest on an accelerated basis on the
Make-Up Vesting Date pursuant to Section 2(b)(i) above over (y) the number of
Scheduled Accelerated Vesting Shares which actually vested on an accelerated
basis on the immediately preceding Accelerated Vesting Date.

following receipt of, the audited financial statements for such fiscal year and

reason, the Option shall, to the extent not then vested, be cancelled by the
Company without consideration and the Vested Portion of the Option shall remain
exercisable for the period set forth in Section 3(a); provided that if the
Participant's employment is terminated by the Company without Cause, by the
Participant for Good Reason or due to the Participant's death or Disability (as
each such term is defined in Section 3(a) below), and the Minimum Annual Price
Target for the Determination Date applicable to the next succeeding Accelerated
Vesting Date is exceeded as of such Determination Date, then the Option shall,
upon the Board's determination that the Minimum Annual Price Target for such
Determination Date has been exceeded, become vested with respect to, and the
Vested Portion of the Option shall include a number of Shares (the "Termination
Shares") equal to the sum of:

            (i) the product of (A) the number of Scheduled Accelerated Vesting
Shares that would otherwise have vested pursuant to Section 2(b)(i) had the
Participant remained employed by the Company through the next succeeding
Accelerated Vesting Date times (B) a fraction, the numerator of which is the
number of days that passed since the immediately preceding Accelerated Vesting
Date through and including the date of the Participant's

termination of employment and the denominator of which is 365 (the "Termination
Fraction"); plus

            (ii) If there were Missed Shares with respect to the immediately
preceding Accelerated Vesting Date, the product of (A) the number of Missed
Shares that would otherwise have vested pursuant to Section 2(b)(ii) had the
Participant remained employed by the Company through the next succeeding
Accelerated Vesting Date times (B) the Termination Fraction.

      (d) Change of Control.

      Notwithstanding any other provisions of this Agreement to the contrary, in
the event of a Change of Control, the Option shall, to the extent not previously
cancelled, immediately become vested and exercisable with respect to the
Scheduled Accelerated Vesting Shares for any remaining future Accelerated
Vesting Dates, if, and only if, in connection with the Change of Control, Vestar
receives aggregate proceeds, in cash, securities or a combination of cash and
securities, having an aggregate Fair Market Value in an amount equal to or in
excess of the product of (i) Vestar's Aggregate Investment (as defined below)
times (ii) the Minimum Investment Multiple (as defined below) applicable to the
fiscal year of the Company in which such Change of Control occurs; provided
that, securities received by Vestar shall be taken into account for purposes
hereof only if such securities are distributed by Vestar, in kind, to its
limited partners.

notice of intent to so exercise; provided that, the Option may be exercised with
respect to whole Shares only. Such notice shall specify the number of Shares for
which the Option is being exercised and shall be accompanied by payment in full

or, subject to the consent of the Committee, in Shares which have been owned by
the Participant for at least six months, such Shares to be valued at their Fair
Market Value as of the date of exercise.

                  (ii) Notwithstanding any other provision of the Plan or this
Agreement to the contrary, the Option may not be exercised prior to the
completion of any registration or qualification of the Option or the Shares that

certificates, or any mistakes or errors in the issuance of the certificates or
in the certificates themselves.

                  (iv) In the event of the Participant's death, the Vested
Portion of the Option shall remain exercisable by a Permitted Transferee, the
Participant's executor or administrator, or the person or persons to whom the
Participant's rights under this Agreement shall pass by will or by the laws of
descent and distribution as the case may be, to the extent set forth in Section
3(a). Any heir or legatee of the Participant shall take rights herein granted
subject to the terms and conditions hereof.

                  (v) As a condition to exercising the Option, the Participant
shall become a party to the Stockholders' Agreement.

            4. No Right to Continued Employment. Neither the Plan nor this
Agreement shall be construed as giving the Participant the right to be retained
in the employ of, or in any consulting relationship to, the Company or any
Affiliate. Further, the Company or an Affiliate may at any time dismiss the
Participant or discontinue any consulting relationship, free from any liability
or any claim under the Plan or this Agreement, except as otherwise expressly
provided herein.

Stockholders' Agreement, the certificates representing the Shares purchased by
exercise of the Option shall contain a legend stating that they are subject to
the Stockholders' Agreement and may be subject to such stop transfer orders and
other restrictions as the Committee may deem advisable under the Plan or the
rules, regulations, and other requirements of the Securities and Exchange
Commission, any stock exchange upon which such Shares are listed, and any
applicable Federal or state laws, and the Committee may cause an additional
legend or legends to be put on any such certificates to make appropriate
reference to such other restrictions.

            6. Transferability. The Option may not be assigned, alienated,
pledged, attached, sold or otherwise transferred or encumbered by the
Participant otherwise than by will or by the laws of descent and distribution,
and any such purported assignment, alienation, pledge, attachment, sale,
transfer or encumbrance shall be void and unenforceable against the Company or
any Affiliate; provided that the designation of a beneficiary shall not
constitute an assignment, alienation, pledge, attachment, sale, transfer or
encumbrance. No such permitted transfer of the Option to heirs or legatees of
the Participant shall be effective to bind the Company unless the Committee
shall have been furnished with written notice thereof and a copy of such
evidence as the Committee may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions hereof. During the Participant's lifetime, the Option is exercisable
only by the Participant.

            Notwithstanding the foregoing, the Participant may transfer all or
any portion of the Option to a Permitted Transferee in accordance with Section
9(a)(ii) of the Plan.

            7. Withholding. A Participant shall be required to pay to the
Company or any Affiliate and the Company shall have the right and is hereby
authorized to withhold, any applicable withholding taxes in respect of an
Option, its exercise or any payment or transfer

                                    EXHIBIT A

             METHODOLOGY FOR DETERMINING WHETHER PERFORMANCE OPTIONS
                       ARE SUBJECT TO ACCELERATED VESTING

STEP 1: CALCULATE PRO FORMA EBITDA. Upon receipt of audited financial statements
for the year, the Company shall calculate (and the Board of Directors shall
review and approve) EBITDA in good faith pro forma to give effect to all
acquisitions and divestitures completed during the year as if they had occurred
on January 1 of such year.

STEP 2: CALCULATE TOTAL ENTERPRISE VALUE. Multiply Pro Forma EBITDA (calculated
in Step 1) by 7.5.

STEP 3: CALCULATE VALUE OF COMMON EQUITY. From Total Enterprise Value
(calculated in Step 2), deduct year-end balances for Total Debt and Other
Obligations, add year-end balance for Total Cash and add Total Option Proceeds.
For purposes of this calculation, Other Obligations includes any debt-like
instruments such as acquisition-related non-compete, consulting or stock price
guarantee payments as well as non-convertible preferred stock and
out-of-the-money convertible securities. Total Option Proceeds should include
options proceeds related to i) all time-based options (whether or not vested),
ii) all performance-based options that have vested in prior years and iii) all
performance-based options that vest in current year.

STEP 4: CALCULATE ENDING FULLY-DILUTED SHARES. Add the following : i) The number
of shares outstanding at the beginning of the year, ii) shares issued in current
year for any reason, including those related to acquisitions, iii) all
time-based options (whether or not vested), iv) all performance-based options
that vest in prior years or in the current year, v) shares associated with
in-the-money convertible preferred stock and vi) shares associated with other
in-the-money common stock equivalents including, but not limited to, warrants
and any other options.

STEP 5: CALCULATE VALUE OF COMMON EQUITY PER SHARE. Divide Value of Common
Equity (calculated in Step 3) by Ending Fully-Diluted Shares (calculated in Step
4). In Step 6, this number will be compared with the maximum and minimum targets
listed below to determine how many (if any) performance-based options vest in
current year.

STEP 6: DETERMINE HOW MANY PERFORMANCE BASED OPTIONS VEST IN CURRENT YEAR.
Multiply the number of options eligible for accelerated vesting in current year
pursuant to the Performance Option Plan by i) if the Value of Common Equity per
Share (Step 5) is greater than or equal to current year's Maximum Annual Price
Target, 100%; ii) if the Value of Common Equity per Share is less than or equal
to current year's Minimum Annual Price Target, 0%; iii) if the Value of Common
Equity per Share is between current year's Minimum and Maximum Annual Price
Targets, the quotient calculated by dividing (A) excess of the Value of Common
Equity per Share over current year's Minimum Annual Price Target by (B) the
excess of current year's Maximum Annual Price Target over current year's Minimum
Annual Price Target.

(c) Other Obligations include any debt-like instruments such as
    acquisition-related noncompete, consulting or stock price guarantee payments
    as well as non-convertible preferred stock and out-of-the-money convertible
    securities.

(d) Option proceeds assume exercise of all vested in-the-money options,
    including those options available for current year vesting. In this example,
    assumes all options have exercise price of $9.25.

(e) For purposes of calculating value of common equity per share on this
    schedule, all time-based options are deemed vested and exercised.

    assumes that all 483,333 are granted.

(g) Assumes a June 30, 1999 closing. If calculated value of common equity per
    share exceeds the maximum annual share price target for that year, then 100%
    of eligible options will vest (0.121 million in this example).

(h) Assumes a June 30, 1999 closing. If calculated value of common equity per
    share is below the minimum annual share price target for that year, then 0%

purchase of shares of common stock of Sheridan pursuant to the Offer.

      (b) Termination of Employment.

      If the Participant's employment with the Company is terminated for any
reason, the Option shall, to the extent not then vested, be cancelled by the
Company without consideration and the Vested Portion of the Option shall remain
exercisable for the period set forth in Section 3(a); provided that if the
Participant's employment is terminated by the Company without Cause, by the
Participant for Good Reason or due to the Participant's death or Disability, the
Option shall, as of the date of such termination, become vested with respect to,

      amended in accordance with the terms thereof), would expressly enable the
      Participant to resign from employment and be treated under such employment
      agreement as though the Participant's employment had been terminated by
      the Company without "cause" or, if the employment agreement does not
      include such provisions or if there shall be no such employment agreement,
      "Good Reason" shall mean: (i) Sheridan, the Company or any Subsidiary has
