                          REGISTRATION RIGHTS AGREEMENT


                                                                 August 31, 1999


To the several persons named in
Schedule I hereto

Ladies and Gentlemen:

                  This will confirm that, in consideration of the purchase by
Welsh, Carson, Anderson & Stowe VIII, L.P., a Delaware limited partnership
("WCAS VIII") and the several other persons named in Schedule I hereto
(collectively with WCAS VIII, the "WCAS Purchasers") from Quorum Health Group,
Inc., a Delaware corporation (the "Company"), of $150,000,000 aggregate
principal amount of the Company's 6% Convertible Subordinated Debentures due
August 31, 2009 (the "WCAS Debentures"), which WCAS Debentures are convertible
into shares (the "Conversion Shares") of Common Stock, $.01 par value ("Common
Stock"), of the Company on the terms set forth therein, all on the terms and
subject to the conditions set forth in the Securities Purchase Agreement dated
as of August 18, 1999 (the "WCAS Purchase Agreement"), among the Company and the
WCAS Purchasers, the Company hereby covenants and agrees with each of you, and
with each subsequent holder of Restricted Stock (as defined herein) as follows:

                  1. Certain Definitions; Inconsistent Provisions. As used
herein, the following terms shall have the following respective meanings:

                  "Commission" means the Securities and Exchange Commission, or
         any other federal agency at the time administering the Securities Act.

                  "Conversion Shares" means the shares of Common Stock into
         which the WCAS Debentures may be converted.

                  "Exchange Act" means the Securities Exchange Act of 1934, as
         amended, or any similar federal statute, and the rules and regulations
         of the Commission thereunder, all as the same shall be in effect at the
         time.

                  "Registration Expenses" means the expenses so described in
         Section 7 hereof.

                  "Restricted Stock" means the shares of capital stock of the
         Company, the certificates for which are required to bear the legend set
         forth in Section 2 hereof.
<PAGE>   2
                  "Securities Act" means the Securities Act of 1933, as amended,
         or any similar federal statute, and the rules and regulations of the
         Commission thereunder, all as the same shall be in effect at the time.

                  "Selling Expenses" means the expenses so described in Section
         7 hereof.

                  2. Restrictive Legend. Each certificate representing the
Conversion Shares and each certificate issued upon exchange, adjustment or
transfer of any of the foregoing, other than in a public sale or as otherwise
permitted by the last paragraph of Section 3 hereof, shall be stamped or
otherwise imprinted with a legend substantially in the following form:

                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE
                  SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THEY HAVE
                  BEEN REGISTERED UNDER THAT ACT OR AN EXEMPTION FROM
                  REGISTRATION IS AVAILABLE.

                  3. Transfer. Each certificate for Restricted Stock transferred
shall bear the legend set forth in Section 2, unless (i) such transfer is in
accordance with the provisions of Rule 144 (or any other rule permitting public
sale without registration under the Securities Act), (ii) such transfer is
pursuant to a public sale as contemplated by Sections 4 or 5 hereof or (iii) an
opinion of counsel reasonably satisfactory to the Company (it being agreed that
Reboul, MacMurray, Hewitt, Maynard & Kristol is and shall be satisfactory) is
rendered to the effect that the proposed transfer of Restricted Stock may be
effected without registration under the Securities Act and the transferee and
any subsequent transferee (other than an affiliate of the Company) would be
entitled to transfer such securities in a public sale without registration under
the Securities Act. The Company acknowledges and agrees that transfer made in
compliance with the Securities Act and applicable state securities or Blue Sky
laws to an entity owning, directly or indirectly, all the common equity of such
holder or any wholly-owned direct or indirect subsidiary of such parent entity
shall be deemed to be in compliance with this Agreement, provided such new
holder shall execute a writing agreeing to be bound hereby.

                  The foregoing restrictions on transferability of Restricted
Stock shall terminate as to any particular shares of Restricted Stock when such
shares shall have been effectively registered under the Securities Act and sold
or otherwise disposed of in accordance with the intended method of disposition
by the seller or sellers thereof set forth in the registration statement
concerning such shares. Whenever a holder of Restricted Stock is able to
demonstrate to the Company (and its counsel) that the provisions of Rule 144(k)
of the Securities Act are available to such holder without limitation, such
holder of Restricted Stock shall be entitled to receive from the Company,
without expense, a new certificate not bearing the restrictive legend set forth
in Section 2.
<PAGE>   3
                  4.  Required Registration.

                  (a) Subject to the provisions of paragraph (e) below, at any
time after the second anniversary of the date hereof and prior to the fifth
anniversary of the date hereof, the holders of Restricted Stock constituting at
least a majority of the Restricted Stock outstanding at such time may request in
writing the Company to register under the Securities Act all or any portion of
the Restricted Stock held by such requesting holder or holders for sale in the
manner specified in such notice; provided, however, that the only securities
which the Company shall be required to register pursuant hereto shall be shares
of Common Stock; and provided further, however, that (i) the aggregate number of
shares of Restricted Stock so requested to be registered shall not be less than
3,333,333 shares, and (ii) the reasonably anticipated price to the public of
such shares shall be at least $37,500,000.

                  (b) As soon as practicable following receipt of any written
notice under this Section 4, the Company shall notify any holders of Restricted
Stock from whom notice has not been received, and shall use its reasonable best
efforts to register under the Securities Act, for public sale in accordance with
the method of disposition specified in such notice from such requesting holders,
the number of shares of Restricted Stock specified in such notice (and the
number of shares of Restricted Stock specified in any notices received from
other such holders of Restricted Stock within 30 days after the date such notice
was sent by the Company); provided, however, that if the proposed method of
disposition specified by the requesting holders of Restricted Stock shall be an
underwritten public offering, the number of shares of Restricted Stock to be
included in such an offering may be reduced if and to the extent that the
managing underwriter shall be of the opinion that such inclusion would adversely
affect the marketing of the Restricted Stock to be sold. If such method of
disposition shall be an underwritten public offering, the Company may designate
the managing underwriter of such offering, subject to the approval of the
selling holders of a majority of the Restricted Stock included in the offering,
which approval shall not be unreasonably withheld. Notwithstanding anything to
the contrary contained herein, the obligation of the Company under this Section
4 shall be deemed satisfied only when a registration statement covering all
shares of Restricted Stock specified in notices received as aforesaid, for sale
in accordance with the method of disposition specified by the requesting holders
of Restricted Stock, shall have become effective and, if such method of
disposition is a firm commitment underwritten public offering, either (i) all
such shares shall have been sold pursuant thereto or (ii) if such number of
shares registered for sale in such underwritten public offering is reduced upon
the advice of the managing underwriter thereof as described above, not less than
75% of all the shares of Restricted Stock that was requested to be included in
such underwriting shall have been sold pursuant thereto, as the case may be.

                  (c) In the event that the Board of Directors of the Company
determines in good faith that the filing of a registration statement pursuant
hereto would be detrimental to the Company, the Board of Directors may defer
such filing for a period not to exceed 180 days. The Board of Directors may not
effect more than 180 days of deferral during any twelve-month period. The
Company's Board of Directors agrees to notify as soon as practicable all holders
of Restricted Stock who requested registration of any such deferral, and shall
provide to such holders a reasonably complete explanation therefor.
<PAGE>   4
                  (d) The Company shall be entitled to include in any
registration statement referred to in this Section 4, for sale in accordance
with the method of disposition specified by the requesting holders, shares of
Common Stock to be sold by the Company for its own account, except to the extent
that, in the opinion of the managing underwriter in an underwritten public
offering, such inclusion would adversely affect the marketing of the Restricted
Stock to be sold.

                  (e) Notwithstanding anything to the contrary contained herein,
the Company shall be obligated to register Restricted Stock pursuant to this
Section 4 on only one occasion.

                  (f) A registration will not be considered to be registration
under this Section 4 unless it has been kept continuously effective for a period
of at least 90 days following the date on which such registration was declared
effective or such shorter period that will terminate when all the Restricted
Stock covered by the registration have been sold pursuant to the terms of such
registration.

                  5. Incidental Registration. If the Company at any time (other
than pursuant to Section 4 hereof) after the second anniversary of the date
hereof and during the term of this Agreement proposes to register any of its
Common Stock under the Securities Act for sale to the public for cash, whether
for its own account or for the account of other security holders or both (except
with respect to registration statements on Form S-4 or Form S-8 or another form
not available for registering the Restricted Stock for sale to the public), it
will give written notice at such time to all holders of outstanding Restricted
Stock of its intention to do so. Upon the written request of any such holder,
given within 30 days after the date any such notice was sent by the Company, to
register any of its Restricted Stock (which request shall state the intended
method of disposition thereof), the Company will use its reasonable best efforts
to cause the Restricted Stock as to which registration shall have been so
requested to be included in the securities to be covered by the registration
statement proposed to be filed by the Company, all to the extent requisite to
permit the sale or other disposition by the holder of such Restricted Stock so
registered with the same intended method of disposition as proposed by the
Company; provided that nothing herein shall prevent the Company from abandoning
or delaying such registration at any time; provided, further, that the only
securities which the Company shall be required to register shall be shares of
Common Stock. In the event that any registration pursuant to this Section 5
shall be, in whole or in part, an underwritten public offering of Common Stock,
the Company may designate the managing underwriter of such offering. The number
of shares of Restricted Stock to be included in an underwriting may be reduced
pro rata among the requesting holders of Restricted Stock and other holders of
Restricted Stock who have exercised similar registration rights (other than such
holders who may have exercised their registration rights to initiate the
registration statement giving rise to the rights of the holders of Restricted
Stock under this Section 5, which holders shall be given priority if the number
of shares registered is reduced) based upon the number of shares of Restricted
Stock so requested to be registered, if and to the extent that the managing
underwriter shall be of the opinion that such inclusion or sale would adversely
affect the marketing of the securities to be sold by the Company therein.
<PAGE>   5
                  Notwithstanding anything to the contrary contained in this
Section 5, in the event that there is an underwritten public offering of
securities of the Company pursuant to a registration covering Restricted Stock
and a holder of Restricted Stock does not elect to sell such holder's Restricted
Stock to the underwriters of the Company's securities in connection with such
offering or such holder's Restricted Stock is excluded from the offering as
provided above, such holder shall refrain from selling such Restricted Stock so
registered pursuant to this Section 5 during the period of distribution of the
Company's securities by such underwriters and the period in which the
underwriting syndicate participates in the after market; provided, however, that
such holder shall, in any event, be entitled to sell its Restricted Stock
commencing on the 90th day after the effective date of such registration
statement or, if later, on such date (but in no event later than the 180th day
after such effective date) as contractual "lock-up" restrictions imposed by the
underwriters shall expire or be released.

                  6. Registration Procedures. If and whenever the Company is
required by the provisions of Section 4 or 5 hereof to use its reasonable best
efforts to effect the registration of any of the Restricted Stock under the
Securities Act, the Company will, as expeditiously as possible:

                  (a) prepare (and afford counsel for the selling holders
         reasonable opportunity to review and comment thereon) and file with the
         Commission a registration statement on the most appropriate form
         adequate for the purposes thereof with respect to such securities and
         use its reasonable best efforts to cause such registration statement to
         become and remain effective for the period of the distribution required
         under the terms of this Agreement;

                  (b) prepare (and afford counsel for the selling holders
         reasonable opportunity to review and comment thereon if time permits)
         and file with the Commission 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 for
         the period required under the terms of this Agreement and to comply
         with the provisions of the Securities Act with respect to the
         disposition of all Restricted Stock covered by such registration
         statement in accordance with the sellers' intended method of
         disposition set forth in such registration statement for such period
         (and in accordance with the terms of this Agreement);

                  (c) furnish to each seller and to each underwriter such number
         of copies of the registration statement and the prospectus included
         therein (including each preliminary prospectus) as such persons may
         reasonably request in order to facilitate the public sale or other
         disposition of the Restricted Stock covered by such registration
         statement;

                  (d) use its reasonable best efforts to register or qualify the
         Restricted Stock covered by such registration statement under the
         securities or blue sky laws of such jurisdictions as the sellers of
         Restricted Stock or, in the case of an underwritten public offering,
         the managing underwriter, shall reasonably request (provided that the
         Company will not be required to (i) qualify generally to do business in
         any jurisdiction where it
<PAGE>   6
         would not otherwise be required to qualify but for this paragraph (d),
         (ii) subject itself to taxation in any such jurisdiction or (iii)
         consent to general service of process in any such jurisdiction);

                  (e) immediately notify each seller under such registration
         statement and each underwriter, at any time when a prospectus relating
         thereto is required to be delivered under the Securities Act, of the
         happening of any event as a result of which the prospectus contained in
         such registration statement, as then in effect, includes an untrue
         statement of a material fact or omits to state any material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in the light of the circumstances then existing
         (following which notification the sellers agree to discontinue sales of
         their Restricted Stock covered by such registration statement until
         such misstatement or omission shall have been remedied);

                  (f) use all reasonable efforts (if the offering is
         underwritten) to furnish, at the request of any seller, on the date
         that Restricted Stock is delivered to the underwriters for sale
         pursuant to such registration: (i) an opinion of counsel representing
         the Company for the purposes of such registration, addressed to the
         underwriters and to such seller and dated such date, stating (A) to the
         best knowledge of such counsel, that such registration statement has
         become effective under the Securities Act, no stop order suspending the
         effectiveness thereof has been issued and no proceedings for that
         purpose have been instituted or are pending or contemplated under the
         Securities Act, (B) the registration statement, the related prospectus,
         and each amendment or supplement thereof comply as to form in all
         material respects with the requirements of the Securities Act and the
         applicable rules and regulations of the Commission thereunder (except
         that such counsel need express no opinion as to financial statements,
         the notes thereto, and the financial schedules and other financial and
         statistical data contained therein), and (C) to such other effects as
         may reasonably be requested by counsel for the underwriters or by such
         seller or its counsel and which are customary in underwritings of the
         type being undertaken, and (ii) a letter dated such date from the
         independent public accountants retained by the Company, addressed to
         the underwriters, stating that they are independent public accountants
         within the meaning of the Securities Act and that, in the opinion of
         such accountants, the financial statements of the Company included in
         the registration statement or the prospectus, or any amendment or
         supplement thereof, comply as to form in all material respects with the
         applicable accounting requirements of the Securities Act, and such
         letter shall additionally cover such other financial matters (including
         information as to the period ending no more than five business days
         prior to the date of such letter) with respect to the registration in
         respect of which such letter is being given as such underwriters or
         seller may reasonably request and which are customary in underwritings
         of the type being undertaken; and

                  (g) make available for inspection by each seller, any
         underwriter participating in any distribution pursuant to such
         registration statement, and any attorney, accountant or other agent
         retained by such seller or underwriter, subject to customary
         undertakings with respect to the confidentiality thereof, all financial
         and other records, pertinent corporate
<PAGE>   7
         documents and properties of the Company, and cause the Company's
         officers, directors and employees to supply all information reasonably
         requested by any such seller, underwriter, attorney, accountant or
         agent in connection with such registration statement and permit such
         seller, attorney, accountant or agent to participate in the preparation
         of such registration statement.

                  In connection with each registration hereunder, the selling
holders of Restricted Stock will furnish to the Company in writing such
information with respect to themselves and the proposed distribution by them as
shall be reasonably necessary in order to assure compliance with federal and
applicable state securities laws.

                  In connection with each registration pursuant to Sections 4
and 5 hereof covering an underwritten public offering, the Company and each
holder of Restricted Stock selling shares in such offering agrees to enter into
a written agreement with the managing underwriter selected in the manner herein
provided in such form (as well as all other customary questionnaires, powers of
attorney, custody agreements and other documents) and containing such provisions
as are customary in the securities business for such an arrangement between
nationally recognized underwriters and companies of the Company's size and
investment stature; provided, however, that such agreement shall not contain any
such provision applicable to the Company or any selling stockholder which is
inconsistent in any material respect with the provisions hereof.

                  7. Expenses. All expenses incurred by the Company in complying
with Sections 4 and 5 hereof, including without limitation all registration and
filing fees, printing expenses, fees and disbursements of counsel and
independent public accountants for the Company, fees of the National Association
of Securities Dealers, Inc., transfer taxes (other than any transfer tax arising
from the transfer of shares by a stockholder to another person other than in
connection with the public sale of such shares), and fees of transfer agents and
registrars, but excluding any Selling Expenses, are herein called "Registration
Expenses." Notwithstanding the foregoing, (i) the Company shall not be required
to pay the fees and expenses of counsel for the holders of Restricted Stock, and
the holders shall be responsible for, and reimburse the Company for, all
Registration Expenses if the registration statement relating to the incurrence
of such expenses was withdrawn at the request of the holders (unless the holders
agree in writing that the withdrawn registration statement counts as a
registration for purposes of Section 4(e) hereof). All underwriting discounts
and selling commissions applicable to the sale of Restricted Stock and other
expenses not required to be paid by the Company are herein called "Selling
Expenses."

                  The Company will pay all Registration Expenses in connection
with each registration statement filed pursuant to Section 4 or 5 hereof. All
Selling Expenses in connection with any registration statement filed pursuant to
Section 4 or 5 hereof shall be borne by the participating sellers in proportion
to the number of shares sold by each, or by such persons other than the Company
(except to the extent the Company shall be a seller) as they may agree.

                  8. Indemnification. In the event of a registration of any of
the Restricted Stock under the Securities Act pursuant to Section 4 or 5 hereof,
the Company will indemnify and hold harmless each seller of such Restricted
Stock thereunder and each underwriter of Restricted
<PAGE>   8
Stock thereunder and each other person, if any, who controls such seller or
underwriter within the meaning of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which such seller or
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Restricted Stock was registered under the Securities Act
pursuant to Section 4 or 5, any preliminary prospectus or final prospectus
contained therein, or any amendment or supplement thereof, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse each such seller, each such underwriter and each
such controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case if and to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission so made in conformity with information
furnished by such seller, such underwriter or such controlling person in writing
specifically for use in such registration statement or prospectus.

                  In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Section 4 or 5 hereof, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless the Company and each person, if any, who controls the Company within
the meaning of the Securities Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the Securities Act,
against all losses, claims, damages or liabilities, joint or several, to which
the Company or such officer, director, underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the registration statement under which such Restricted Stock
was registered under the Securities Act pursuant to Section 4 or 5, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereof, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company and each such officer, director, underwriter and controlling person for
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that such seller will be liable hereunder in any such case if
and only to the extent that any such loss, claim, damage or liability arises out
of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission made in reliance upon and in conformity with information
pertaining to such seller, as such, furnished in writing to the Company by such
seller specifically for use in such registration statement or prospectus; and
provided, further, that the liability of each seller hereunder shall be limited
to the proceeds (net of underwriting discounts and commissions) received by such
seller from the sale of Restricted Stock covered by such registration statement.
<PAGE>   9
                  Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to any indemnified party except to the extent the indemnified party is
materially prejudiced thereby or other than under this Section 8. In case any
such action shall be brought against any indemnified party and it shall notify
the indemnifying party of the commencement thereof, the indemnifying party shall
be entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel reasonably satisfactory to such
indemnified party, and, after notice from the indemnifying party to such
indemnified party of its election so to assume and undertake the defense
thereof, the indemnifying party shall not be liable to such indemnified party
under this Section 8 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected; provided,
however, that if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be reasonable defenses available to it which are
different from or additional to those available to the indemnifying party, or if
the interests of the indemnified party reasonably may be deemed to conflict in
any material respect with the interests of the indemnifying party, the
indemnified party shall have the right to select a separate counsel and to
assume such legal defenses and otherwise to participate in the defense of such
action, with the reasonable expenses and fees of such separate counsel and other
reasonable expenses related to such participation to be reimbursed by the
indemnifying party as incurred.

                  Notwithstanding the foregoing, any indemnified party shall
have the right to retain its own counsel in any such action, but the fees and
disbursements of such counsel shall be at the expense of such indemnified party
unless (i) the indemnifying party shall have failed to retain counsel for the
indemnified person as aforesaid, (ii) the indemnifying party and such
indemnified party shall have mutually agreed to the retention of such counsel or
(iii) in the circumstances described in the proviso at the end of the
immediately preceding paragraph. It is understood that the indemnifying party
shall not, in connection with any action or related actions in the same
jurisdiction, be liable for the fees and disbursements of more than one separate
firm qualified in such jurisdiction to act as counsel for all of the indemnified
parties. The indemnifying party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent, the indemnifying party agrees to indemnify the indemnified party from
and against any loss or liability by reason of such settlement.

                  If the indemnification provided for in the first two
paragraphs of this Section 8 is unavailable or insufficient to hold harmless an
indemnified party under such paragraphs in respect of any losses, claims,
damages or liabilities or actions in respect thereof referred to therein for any
reason other than any exclusion or limitation expressly stated in such
paragraphs, then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages, liabilities or actions in
such proportion as appropriate to reflect the relative fault of the Company, on
the one hand, and the underwriters and the sellers of such Restricted Stock, on
the other, in
<PAGE>   10
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or actions as well as any other relevant equitable
considerations, including the failure to give any notice under the third
paragraph of this Section 8. The relative fault shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact relates to information supplied by the Company, on the one hand,
or the underwriters and the sellers of such Restricted Stock, on the other, and
to the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
each of you agree that it would not be just and equitable if contributions
pursuant to this paragraph were determined by pro rata allocation (even if all
of the sellers of such Restricted Stock were treated as one entity for such
purpose) or by any other method of allocation which did not take account of the
equitable considerations referred to above in this paragraph. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages,
liabilities or action in respect thereof, referred to above in this paragraph,
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this paragraph, the sellers
of such Restricted Stock shall not be required to contribute any amount in
excess of the amount, if any, by which the total price at which the Common Stock
sold by each of them was offered to the public exceeds the amount of any damages
which they would have otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission and subject to reasonable limitations on
the contribution obligations of underwriters. No person guilty of fraudulent
misrepresentations (within the meaning of Section 11(f) of the Securities Act),
shall be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation.

                  The indemnification and contribution of underwriters provided
for in this Section 8 shall be on such other terms and conditions as are at the
time customary and reasonably required by such underwriters. In that event, the
indemnification and contribution of the sellers of Restricted Stock in such
underwriting shall at the sellers' request be modified to conform to such terms
and conditions.

                  9. Changes in Common Stock. If, and as often as, there are any
changes in the Common Stock by way of stock split, stock dividend, combination
or reclassification, or through merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof, as may be required, so that the rights and privileges
granted hereby shall continue with respect to the Common Stock as so changed.

                  10. Rule 144 Reporting. The Company agrees with you as
follows:

                  (a) The Company shall make and keep public information
         available, as those terms are understood and defined in Rule 144(c)(1)
         or (c)(2), whichever is applicable, under the Securities Act, at all
         times from and after the date it is first required to do so.

                  (b) The Company shall file with the Commission in a timely
         manner all reports and other documents as the Commission may prescribe
         under Section 13(a) or 15(d) of
<PAGE>   11
         the Exchange Act at all times during which the Company is subject to
         such reporting requirements of the Exchange Act.

                  (c) The Company shall furnish to such holder of Restricted
         Stock as promptly as practicable upon request (i) a written statement
         by the Company as to its compliance with the reporting requirements of
         Rule 144 (at any time from and after the date it first becomes subject
         to such reporting requirements) and of the Securities Act and the
         Exchange Act (at any time during which it is subject to such reporting
         requirements), (ii) a copy of the most recent annual or quarterly
         report of the Company and (iii) such other reports and documents so
         filed as a holder may reasonably request to avail itself of any rule or
         regulation of the Commission allowing a holder of Restricted Stock to
         sell any such securities without registration.

                  11.  Miscellaneous.

                  (a) All covenants and agreements contained in this Agreement
by or on behalf of any of the parties hereto shall bind and inure to the benefit
of the respective successors and assigns of the parties hereto whether so
expressed or not until the expiration of this Agreement on August 31, 2009.
Without limiting the generality of the foregoing, the registration rights
conferred herein on the holders of Restricted Stock shall inure to the benefit
of any and all subsequent holders from time to time of the Restricted Stock for
so long as the certificates representing the Restricted Stock shall be required
to bear the legend specified in Section 2 hereof.

                  (b) Any notice or other communications required or permitted
hereunder shall be deemed to be sufficient if contained in a written instrument
