with the matters set forth in Sections 2.1 and 2.2 hereof in accordance with the
provisions of Sections 2.1 and 2.2 hereof. Each of the proxies granted hereby is

this Section 2, the Secretary of each of the Company and each Subsidiary of the
Company, or if there be no Secretary such other officer of the Company or such
Subsidiary as the Board of Directors of the Company or such Subsidiary may
appoint to fulfill the duties of the Secretary, shall not record any vote or

all applicable state securities or "blue sky" laws or (ii) such Stockholder

            3.5 Tag-Along Rights. (a) So long as this Agreement shall remain in
effect, with respect to any proposed Transfer by any of Vestar and its

permitted hereunder, other than as provided in Section 3.2(b) and 3.6, the
Transferring Stockholder shall have the obligation, and each other Stockholder
(other than Vestar or any of its Affiliates) shall have the right, to require
the proposed transferee to purchase from each such other Stockholder having and
exercising such right (each a "Tagging Stockholder") a number of shares of
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
least 45 days prior to the proposed consummation of such Transfer, setting forth
the name of the Transferring Stockholder, the number of shares of Common Stock
proposed to be so Transferred, the name and address of the proposed transferee,
the proposed amount and form of consideration, the other terms and conditions of
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 

   18
                                                                              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 

   19
                                                                              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

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

   20
                                                                              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

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,

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 

   21
                                                                              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 

   22
                                                                              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

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 

   23
                                                                              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 

   24
                                                                              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 

   25
                                                                              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 

   26
                                                                              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 

   27
                                                                              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

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

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)).

   28
                                                                              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 

   29
                                                                              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 

   30
                                                                              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 

   31
                                                                              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;

   32
                                                                              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 

   33
                                                                              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:

   34
                                                                              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

   35
                                                                              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.

   36
                                                                              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.

   37
                                                                              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

   38
                                                                              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.

            5.5 Amendments. This Agreement may be amended only by a written
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
power represented by all Securities outstanding on a fully diluted basis and
owned by all Stockholders other than Vestar and its Affiliates.

   39
                                                                              36


            5.6 Successors, Assigns and Transferees. The provisions of this
Agreement shall be binding upon and shall inure to the benefit of the parties
hereto and their Permitted Transferees and their respective successors, each of
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.

construed and enforced in accordance with the laws of the State of New York,
except for matters directly within the purview of the General Corporation Law of

Company agreeing to be bound by the terms hereof in the same manner as the other
Management Investors. Each such supplementary agreement shall become effective
upon its execution by the Company and such employee or director, and it shall
not require the signature or consent of any other party hereto. Such

hereby designates and appoints (and each Permitted Transferee of each such
Management Investor shall be deemed to have so designated and appointed)
Mitchell Eisenberg, with full power of substitution (the "Management Investor
Representative") as the representative of each such Person to perform all such
acts as are required, authorized or contemplated by this Agreement to 

   41
                                                                              38


be performed by any such Person and hereby acknowledges that the Management
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
death or incapacity of such Person. Each such Person hereby authorizes (and each
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
the Company. Whenever any action or consent (but not any forbearance) is
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.

   42
                                                                              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.

                                                                              40
