         In May of each year commencing in 2001, you shall be awarded an annual
bonus based on the positive current year performance of the Company as compared
to fiscal Year 2000. The bonus to be awarded in May 2001, 2002, 2003 and upon
the successive annual renewals, shall be based under an incentive compensation
plan which equals $1,000.00 for each penny of additional after tax earnings
incrementally earned over the prior years fiscal earnings.

         The E.P.S. shall be the basic earnings per share of common stock of the
Company as determined by the Company's auditors in the preparation of the annual

review.

Directors  you shall  receive 100% of your base annual salary for the first year

payments received under a disability  insurance policy maintained by the Company
or you (Disability Insurance).  Thereafter, and for the following six months you
shall  receive  50% of your base annual  salary  during the period of such total
disability  reduced  by the  amount of any such  Disability  Insurance.  If such
disability  continues after such 18 month period your employment hereunder shall
terminate.

    ---------------
       Except as required in your  duties to the  Company,  you shall not at any
time during your employment and for a period of six months thereafter,  directly

present value of your base salary in effect at the time of the change of control
for 2 years or the  present  value of your base  salary in effect at the time of
the  change of  control  for the  remainder  of the term and (ii) the  estimated
amount  which would have been  payable to you pursuant to the bonus as set forth
in this  agreement  for the  fiscal  year  during  which the  change of  control
occurred as determined in good faith by the Compensation  Committee of the Board
of Directors of the Company based upon the Company's  results of operations  for
the fiscal year through the effective date of the termination and its historical
results of operations  and pro-rated to the effective date of  termination.  You
shall not be required to mitigate  the amount of  termination  payment  provided
pursuant  to this  section  nor will such  payment  be reduced by reason of your
securing other employment.

A change of control shall have occurred (i) upon the  acquisition  of any person

Exchange Act of 1934 as amended),  directly or  indirectly  of securities of the
Company  representing  66  2/3%  or more of the  combined  voting  power  of the
Company's then outstanding securities or (ii) upon the future disposition by the
Company  (whether  direct  or  indirect  by  sale  of  assets  or  stock  merger
consolidation  or  otherwise)  of all  or  substantially  all  of the  Company's
business and/or assets in the transaction.

In the event of a future  disposition by the Company (whether direct or indirect
by sale of  assets or  stock,  merger,  consolidation  or  otherwise)  of all or
substantially  all of its  business  and/or  assets the Company will require any
successor  to expressly  assume and agree to perform this  agreement in the same
manner and to the same extent that the Company would be required to perform, if

in any jurisdiction shall be ineffective in such jurisdiction to the extent that

(for purposes of this Agreement, "Registrable Investor Securities" shall mean
                                  -------------------------------
Registrable Securities constituting Investor Shares). The Company will then use
its best efforts to effect the registration under the Securities Act of the
Registrable Securities which the Company has been requested to register by such
Initiating Investors together with all other Registrable Securities which the
Company has been requested to register pursuant to Section 8.3 (which request
shall specify the intended method of disposition of such Registrable
Securities), all to the extent requisite to permit the disposition (in
accordance with the intended methods thereof as aforesaid) of the Registrable
Securities which the Company has been so requested to register; provided,
                                                                --------

               date of any registration statement pertaining to an underwritten
               public offering of securities of the Company for its own account
               (other than a Rule 145 Transaction, or a registration relating
               solely to employee benefit plans);

                    (b)  (i) On any form other than Form S-3 (or any successor
               form) if the Company has previously effected five or more
               registrations of Registrable Securities under this Section 8.1.1
               on any form other than Form S-3 (or any successor form);
               provided, however, that no registrations of Registrable
               --------  -------
               Securities which shall not have become and remained effective in
               accordance with the provisions of this Section 8, and no
               registrations of Registrable Securities pursuant to which the

               include, shall be included in the calculation of numbers of
               registrations contemplated by this clause (b);

                    (c)  If the Company shall have furnished to the Initiating
               Investors and such other holders of Registrable Securities which
               the Company has been requested to register pursuant to this
               Section 8.1.1 a certificate, signed by the President of the
               Company, stating that in the good faith judgment of the Board it
               would be seriously detrimental to the Company and its
               shareholders for such Registration Statement to be filed at the
               date filing would have been required, in which case the Company
               shall have an additional period of not more than 60 days within
               which to file such Registration Statement; provided, however,
                                                          --------  -------
               that the Company shall not so postpone a registration pursuant to
               this clause (c) more than once in any twelve month period;

                    (d)  On any form other than Form S-3 (or any successor
               form), if the anticipated aggregate offering price to the public
               of the Registrable Securities to be included in the registration
               by all holders is less than $5,000,000; or

                    (e)  After five years after the closing of the Initial
               Public Offering.

               8.1.1.1.  Form.  Except as otherwise provided above, each
                         ----
     registration requested pursuant to this Section 8.1.1 shall be effected by
     the filing of a registration statement on Form S-1 (or any other form which
     includes substantially the same information as would be required to be
     included in a registration statement on such form as currently
     constituted), unless the use of a different form has been agreed to in
     writing by holders of at least a majority of the Registrable Investor
     Securities to be included in the proposed registration statement in
     question (the "Majority Participating Investors").
                    --------------------------------

<PAGE>

shall include such information in the written notices to holders of Registrable
Securities referred to in Section 8.3. In such event, the right of any holder of

participation in such underwriting and the inclusion of such holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed
upon by the Majority Participating Investors and such holder) to the extent
provided herein. If requested by such underwriters, the Company together with
the holders of Registrable Securities proposing to distribute their securities
through such underwriting will enter into an underwriting agreement with such
underwriters for such offering containing such representations and warranties by
the Company and such holders and such other terms and provisions as are
customarily contained in underwriting agreements with respect to secondary
distributions, including, without limitation, customary indemnity and
contribution provisions.

8.2. DI Investors Demand Registration Rights.
     ---------------------------------------

       8.2.1.  General.   To the extent DI Investors, L.L.C. or its Affiliates
               -------
hold at least 50% of the Shares issued to them by the Company in connection with

the intended method or methods of disposition, may request that the Company
effect the registration under the Securities Act for a Public Offering of all or

                                            ----------------------------
mean Registrable Securities constituting Other Shares).  The Company will then
use its reasonable efforts to effect the registration under the Securities Act
of the Registrable Securities which the Company has been requested to register
by such Initiating Other Investors together with all other Registrable
Securities which the Company has been requested to register pursuant to Section
8.3 (which request shall specify the intended method of disposition of such
Registrable Securities), all to the extent requisite to permit the disposition
(in accordance with the intended methods thereof as aforesaid) of the
Registrable Securities which the Company has been so requested to register;
provided, however, that the Company shall not be obligated to take any action to
--------  -------
effect any such registration pursuant to this Section 8.2.1:

          (a)  If the Company has previously effected two registrations of
     Registrable Securities under this Section 8.2.1; provided, however, that no
                                                      --------  -------
     registrations of Registrable Securities which either (i) shall not have
     become and remained effective in accordance with the provisions of this
     Section 8 or (ii) shall not have enabled the Initiating Other Investors to
     include in such registration at least 90% of the Registrable Securities
     which they desired to

                                      -5-

     securities of the Company for its own account (other than a registration on
     Form S-4 relating solely to a Rule 145 Transaction, or a registration
     relating solely to employee benefit plans);

          (d)  If the Company shall have furnished to the Initiating Other
     Investors and such other holders of Registrable Securities which the
     Company has been requested to register pursuant to this Section 8.2.1 a
     certificate, signed by the President of the Company, stating that in the
     good faith judgment of the Board it would be seriously detrimental to the
     Company and its shareholders for such Registration Statement to be filed at
     the date filing would have been required, in which case the Company shall
     have an additional period of not more than 60 days within which to file
     such Registration Statement; provided, however, that the Company shall not
                                  --------  -------
     so postpone a registration pursuant to this clause (d) more than once in

          (f)  After five years after the closing of the Initial Public
     Offering.

          8.2.1.1.  Form.  Each registration requested pursuant to this Section
                    ----
     8.2.1 shall be effected by the filing of a registration statement on Form
     S-3 (or any successor form).

     8.2.2.    Payment of Expenses.   The Company shall pay all reasonable
               -------------------
expenses of holders of Other Shares incurred in connection with each
registration of Registrable Securities requested pursuant to this Section 8.2,
other than underwriting discount and commission, if any, and applicable transfer
taxes, if any.

     8.2.3.    Additional Procedures.  In the case of a registration pursuant to
               ---------------------
Section 8.2 hereof, whenever the Initiating Other Investors shall request that
such registration shall be effected pursuant to an underwritten offering, the
Company shall include such information in the written notices to holders of
Registrable Securities referred to in Section 8.3.  In such event, the right of
any holder of Registrable Securities to have securities owned by such holder
included in such registration pursuant to Section 8.2 shall be conditioned upon
such holder's participation in such

                                      -6-
<PAGE>

underwriting and the inclusion of such holder's Registrable Securities in the
underwriting (unless otherwise mutually agreed upon by the Majority
Participating Other Investors and such holder) to the extent provided herein. If
requested by such underwriters, the Company together with the holders of
Registrable Securities proposing to distribute their securities through such
underwriting will enter into an underwriting agreement with such underwriters
for such offering containing such representations and warranties by the Company
and such holders and such other terms and provisions as are customarily
contained in underwriting agreements with respect to secondary distributions,
including, without limitation, customary indemnity and contribution provisions.

     8.2A.1.   General.  At any time between the 180th and 360th day following
               -------
the effective date of the Initial Public Offering, NatWest Investors holding a
majority of the Registrable Securities originally issued to the NatWest
Investors by the Company, by notice to the Company (with a copy to the

Registrable Securities to be so registered, may request that the Company effect
the registration under the Securities Act for a Public Offering of up to 50% of
the Registrable Securities held by the NatWest Investors. Upon receipt of such
notice, the Company will give notice to the MCM Managers of the receipt of such
notice. Any such MCM Manager, by written response delivered to the Company
within 20 days after the effectiveness of such notice, which response shall
include a certification by such MCM Manager of his bona fide intention to sell
the number of his Registrable Securities to be so registered, may request that
up to 44.44% of the Registrable Securities held by such MCM Manager be included
in such registration. The Company will then use its best efforts to effect the
registration under the Securities Act of the Registrable Securities which the
Company has been requested to register pursuant to this Section 8.2A.1 by the
NatWest Investors and the MCM Managers, to the extent requisite to permit the
disposition (in accordance with the intended methods thereof as aforesaid) of
the Registrable Securities which the Company has been so requested to register;
provided, however, that the Company shall not take any action to effect any such
--------  -------
registration pursuant to this Section 8.2A.1:

          to include at least 50% of their Registrable Securities and the MCM
          Managers have the right to include at least 44.44% of their
          Registrable Securities pursuant to Section 8.3;

                                      -7-
<PAGE>

               (b)  During any period during which the Company or the Initiating
          Investors are actively planning an underwritten offering of securities
          of the Company in connection with which the NatWest Investors and the
          MCM Managers would have the right to include Registrable Securities
          pursuant to Section 8.3; or

               (c)  If the Company shall have furnished to the NatWest Investors
          a certificate, signed by the President of the Company, stating that in
          the good faith judgment of the Board it would be seriously detrimental
          to the Company and its shareholders for such Registration Statement to
          be filed at the date filing would have been required, in which case
          the Company shall have an additional period of not more than 60 days
          within which to file such Registration Statement.

     8.2A.2.   Payment of Expenses.  The Company shall pay all reasonable
               -------------------
expenses of the NatWest Investors incurred in connection with each registration
of Registrable Securities requested pursuant to this Section 8.2A, other than
underwriting discount and commission, if any, and applicable transfer taxes, if

     8.2A.3.   No Underwritten Offering.  Any registration pursuant to Section
               ------------------------
8.2A.1 hereof may not be effected pursuant to an underwritten offering.

               -------------------
8.3.1.1, except as provided in Section 8.2A.1, no holder of Registrable
Securities shall have the right to have any such Registrable Securities included
in a registration requested pursuant to Section 8.2A.1.

     8.2A.5.   Black-out Period.  Notwithstanding the provisions of Section
               ----------------
8.4.2, at any time during the 60 days during which a registration statement
filed pursuant to this Section 8.2A is required to be kept effective, if the
Company furnishes to the NatWest Investors and the MCM Managers a certificate,
signed by the President of the Company, stating that in the good faith judgment
of the Board it would be seriously detrimental to the Company and its
shareholders for the effectiveness of such registration statement to be
maintained, the NatWest Investors and the MCM Managers shall not Transfer any
Common Stock for a period of up to 30 days as determined by the Company. The 60
day period referenced in Section 8.4.2 shall be extended by the number of days
during which the NatWest Investors and the MCM Managers are prohibited from
Transferring Common Stock pursuant to this Section, however in no case shall the
Company be required to maintain the effectiveness of a registration statement

     -----------------------------

     8.3.1.    Piggyback Registration.
               ----------------------

               8.3.1.1.  General.  Each time the Company proposes to register
                         -------
any shares of Common Stock under the Securities Act on a form which would permit
registration of Registrable Securities for sale to the public, for its own
account or for the account of any holder of its shares of Common Stock, for sale
in a Public Offering, the Company will give notice to all holders of shares of
Common Stock of its intention to do so. Any such holder may, by written response
delivered to the Company within 20 days after the effectiveness of such notice,
request that all or a specified part of the Registrable Securities held by such
holder be included in such registration. The Company thereupon will use its
reasonable efforts to cause to be included in such registration under the
Securities Act all shares of Common Stock which the Company has been so
requested to register by such holders, to the extent required to permit the
disposition (in accordance with the methods to be used by the Company or other
holders of shares of Common Stock in such Public Offering) of the Registrable
Securities to be so registered. No registration of Registrable Securities
effected under this Section 8.3 shall relieve the Company of any of its
obligations to effect registrations of Registrable Securities pursuant to
Section 8.1 hereof.

          8.3.1.2.  Excluded Transactions.  The Company shall not be obligated
                    ---------------------
to effect any registration of Registrable Securities under this Section 8.3
incidental to the registration of any of its securities in connection with:

               (a)  Any Public Offering relating to employee benefit plans or
          dividend reinvestment plans;

               (b)  Any Public Offering relating to the acquisition or merger
          after the date of the Original Agreement by the Company or any of its
          subsidiaries of or with any other businesses; or

               (c)  Any Public Offering initiated by the NatWest Investors
          pursuant to Section 8.2A.1.

     8.3.2.    Payment of Expenses.  The Company shall pay all reasonable
               -------------------
expenses of holders of Registrable Securities incurred in connection with each
registration of Registrable Securities requested pursuant to this Section 8.3,
other than underwriting discount and commission, if any, and applicable stamp or
transfer taxes, if any; provided, however, that the Company shall not be
                        --------  -------
required to pay in respect of the fees and expenses of any attorneys or other
advisers retained by such holders more than an aggregate for all such holders of
$25,000 in the case of each such registration.

                                      -9-
<PAGE>

     8.3.3.    Additional Procedures.  Holders of Shares participating in any
               ---------------------
Public Offering pursuant to this Section 8.3 shall take all such actions and
execute all such documents and instruments that are reasonably requested by the
Company to effect the sale of their Shares in such Public Offering, including,
without limitation, being parties to the underwriting agreement entered into by
the Company and any other selling shareholders in connection therewith and being
liable in respect of the representations and warranties by, and the other
agreements (including customary selling stockholder indemnifications and "lock-
up" agreements) on the part of, the Company and any other selling shareholders
to and for the benefit of the underwriters in such underwriting agreement;
provided, however, that (i) with respect to individual representations,
--------  -------
warranties and agreements of sellers of Shares in such Public Offering, the
aggregate amount of such liability shall not exceed such holder's net proceeds
from such offering and (ii) with respect to all other representations,
warranties and agreements of sellers of shares in such Public Offering, the
aggregate amount of such liability shall not exceed the lesser of (a) such
holder's pro rata portion of any such liability, in accordance with such
holder's portion of the total number of Shares included in the offering or (b)
such holder's net proceeds from such offering.

8.4. Certain Other Provisions.
     ------------------------

     8.4.1.    Underwriter's Cutback.  In connection with any registration of
               ---------------------
shares in an underwritten offering, the underwriter may determine that marketing
factors (including, without limitation, an adverse effect on the per share
offering price) require a limitation of the number of shares to be underwritten.
Notwithstanding any contrary provision of this Section 8 and subject to the
terms of this Section 8.4.1, the underwriter may limit the number of shares
which would otherwise be included in such registration by excluding any or all
Registrable Securities from such registration (it being understood that the
number of shares which the Company seeks to have registered in such registration
shall not be subject to exclusion, in whole or in part, under this Section
8.4.1).  Upon receipt of notice from the underwriter of the need to reduce the
number of shares to be included in the registration, the Company shall advise
all holders of the Company's securities that would otherwise be registered and
underwritten pursuant hereto, and the number of shares of such securities,
including Registrable Securities, that may be included in the registration shall
be allocated in the following manner, unless the underwriter shall determine
that marketing factors require a different allocation:  shares, other than
Registrable Securities, requested to be included in such registration by
shareholders shall be excluded; and, if a limitation on the number of shares is
still required, the number of Registrable Securities that may be included in
such registration shall be allocated among the holders thereof in proportion, as
nearly as practicable, to the respective amounts of Registrable Securities which
each such holder requested be registered in such registration.  For purposes of
any underwriter cutback, all Registrable Securities held by any holder of
Registrable

                                      -10-
<PAGE>

Securities which is a partnership, corporation or limited liability company
shall also include any Registrable Securities held by the partners, retired
partners, shareholders, members or affiliated entities of such holder, or the
estates and family members of any such partners, retired partners and members
and any trusts for the benefit of any of the foregoing persons, and such holder
and other persons shall be deemed to be a single selling holder, and any pro
rata reduction with respect to such selling holder shall be based upon the
aggregate amount of Registrable Securities owned by all entities and individuals
included in such selling holder, as defined in this sentence. No securities
excluded from the underwriting by reason of the underwriter's marketing
limitation shall be included in such registration. If any holder of Registrable
Securities disapproves of the terms of the underwriting, it may elect to
withdraw therefrom by written notice to the Company and the underwriter. The
Registrable Securities so withdrawn shall also be withdrawn from registration.

     8.4.2.    Other Actions.  If and in each case when the Company is required
               -------------
to use its best efforts to effect a registration of any Registrable Securities
as provided in this Section 8, the Company shall take appropriate and customary
actions in furtherance thereof, including, without limitation: (i) promptly
filing with the Commission a registration statement and using reasonable efforts
to cause such registration statement to become effective, (ii) preparing and
filing with the Commission such amendments and supplements to such registration
statements as may be required to comply with the Securities Act and to keep such
registration statement effective for a period not to exceed 270 days (or 60 days
in the case of a registration statement filed pursuant to Section 8.2A) from the
date of effectiveness or such earlier time as the Registrable Securities covered
by such registration statement shall have been disposed of in accordance with
the intended method of distribution therefor or the expiration of the time when
a prospectus relating to such registration is required to be delivered under the
Securities Act, (iii) use its best efforts to register or qualify such
Registrable Securities under the state securities or "blue sky" laws of such
jurisdictions as the sellers shall reasonably request; provided, however, that
                                                       --------  -------
the Company shall not be obligated to file any general consent to service of
process or to qualify as a foreign corporation in any jurisdiction in which it
is not so qualified or to subject itself to taxation in respect of doing
business in any jurisdiction in which it would not otherwise be so subject; and
(iv) otherwise cooperate reasonably with, and take such customary actions as may
reasonably be requested by the holders of Registrable Securities in connection
with, such registration.

     8.4.3.    Selection of Underwriters and Counsel.  The underwriters and
               -------------------------------------
legal counsel to be retained in connection with any Public Offering shall be
selected by the Board or, in the case of an offering following a request
therefor under Section 8.1.1, the Initiating Investors.

                                      -11-
<PAGE>

     8.4.4.    Lock-Up.  Without the prior written consent of the underwriters
               -------
managing the IPO, for a period beginning seven days immediately preceding and
ending on the 180th day following the effective date of the registration
statement used in connection with such offering, no holder of Shares (whether or
not a selling shareholder pursuant to such registration statement) shall
Transfer any Common Stock except pursuant to such registration statement or to a
Permitted Transferee in accordance with the terms of this Agreement.  In the
case of any Public Offering that is not the IPO or effected pursuant to Section
8.2A, each holder of Shares agrees to enter into a reasonable form of agreement,
approved by the Company, restricting the Transfer of any Common Stock for up to
90 days following the effective date of the registration statement used in
connection with such offering if the underwriters managing such Public Offering
demand such an agreement.

     8.5. Indemnification and Contribution.
          --------------------------------

     8.5.1.    Indemnities of the Company.  In the event of any registration of
               --------------------------

otherwise, and in connection with any registration statement or any other

hereby do, and will cause each of their respective subsidiaries, jointly and
severally to, indemnify and hold harmless each seller of Registrable Securities,
any Person who is or might be deemed to be a controlling Person of the Company
or any of its subsidiaries within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act, their respective direct and indirect

                                                                     -------
Person"), against any losses, claims, damages or liabilities, joint or several,
------
to which such Covered Person may be or become subject under the Securities Act,
the Exchange Act, any other securities or other law of any jurisdiction, the
common law or otherwise, insofar as such losses, claims, damages or liabilities

(i) any untrue statement or alleged untrue statement of any material fact
contained or incorporated by reference in any registration statement under the
Securities Act, any preliminary prospectus or final prospectus included therein,
or any related summary prospectus, or any amendment or supplement thereto, or
any document incorporated by reference therein, or any other such disclosure
document (including without limitation reports and other documents filed under
the Exchange Act and any document incorporated by reference therein) or

relating to action or inaction in connection with any such registration,
disclosure document or other document or report, and will reimburse such Covered
Person for any legal or any other expenses incurred by it in connection with
investigating or defending any such loss, claim, damage, liability, action or
proceeding; provided, however, that neither the Company nor any of its
            --------  -------
subsidiaries shall be liable to any Covered Person in any such case to the
extent that any such loss, claim, damage, liability, action or proceeding arises
out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in such registration statement, any such
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement, incorporated document or other such disclosure document or other
document or report, in reliance upon and in conformity with written information
furnished to the Company or to any of its subsidiaries through an instrument
duly executed by such Covered Person specifically stating that it is for use in
the preparation thereof. The indemnities of the Company and of its subsidiaries
contained in this Section 8.5.1 shall remain in full force and effect regardless
of any investigation made by or on behalf of such Covered Person and shall
survive any transfer of securities.

     8.5.2.    Indemnities to the Company.  The Company and any of its
               --------------------------
subsidiaries may require, as a condition to including any securities in any
registration statement filed pursuant to this Section 8, that the Company and
any of its subsidiaries shall have received an undertaking satisfactory to it
from the prospective seller of such securities, to indemnify and hold harmless
the Company and any of its subsidiaries, each director of the Company or any of
its subsidiaries, each officer of the Company or any of its subsidiaries who
shall sign such registration statement and each other Person (other than such

with respect to any statement in or omission from such registration statement,
any preliminary prospectus or final prospectus included therein, or any
amendment or supplement thereto, or any other disclosure document (including,
without limitation, reports and other documents filed under the Exchange Act or
any document incorporated therein) or other document or report, if such

instrument executed by such seller specifically stating that it is for use in

prospectus, summary prospectus, amendment or supplement, incorporated document
or other document or report.  Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of

the Company, any of its subsidiaries or any such director, officer or

     8.5.3.  Indemnification Procedures.  Promptly after receipt by a Person
             --------------------------
entitled to indemnification pursuant to the foregoing provisions of this Section
8.5 (an "Indemnitee") of notice of the commencement of any action or proceeding
         ----------
involving a claim of the type referred to in the foregoing provisions of this
Section 8.5, such Indemnitee will, if a claim in respect thereof is to be made
by such Indemnitee against any indemnifying party, give written notice to each
such indemnifying party of the commencement of such action; provided, however,
                                                            --------  -------
that the failure of any Indemnitee to give notice to such indemnifying party as
provided herein shall not relieve any indemnifying party of its obligations
under the foregoing provisions of this Section 8.5, except and solely to the
extent that such indemnifying party is actually and materially prejudiced by
such failure to give notice.  In case any such action is brought against an
Indemnitee, each indemnifying party will be entitled to participate in and to
assume the defense thereof, jointly with any other indemnifying party similarly
notified, to the extent that it may wish, with counsel reasonably satisfactory
to such Indemnitee (who shall not, except with the consent of the Indemnitee, be
counsel to such an indemnifying party), and after notice from an indemnifying
party to such Indemnitee of its election so to assume the defense thereof, such
indemnifying party will not be liable to such Indemnitee for any legal or other
expenses subsequently incurred by the latter in connection with the defense
thereof; provided, however, that (i) if the Indemnitee reasonably determines
         --------  -------
that there may be a conflict between the positions of such indemnifying party
and the Indemnitee in conducting the defense of such action or if the Indemnitee
reasonably concludes that representation of both parties by the same counsel
would be inappropriate due to actual or potential differing interests between
them, then counsel for the Indemnitee shall conduct the defense to the extent
reasonably determined by such counsel to be necessary to protect the interests
of the Indemnitee and such indemnifying party shall employ separate counsel for
its own defense, (ii) in any event, the Indemnitee shall be entitled to have
counsel chosen by such Indemnitee participate in, but not conduct, the defense
and (iii) the indemnifying party shall bear the legal expenses incurred in
connection with the conduct of, and the participation in, the defense as
referred to in clauses (i) and (ii) above.  If, within a reasonable time after
receipt of the notice, such indemnifying party shall not have elected to assume
the defense of the action, such indemnifying party shall be responsible for any
legal or other expenses incurred by such Indemnitee in connection with the
defense of the action, suit, investigation, inquiry or proceeding.  No
indemnifying party will consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnitee of a release from all liabilities
in respect of such claim or litigation.

     8.5.4.  Contribution.  If the indemnification provided for in Sections
             ------------
8.5.1 or 8.5.2 hereof is unavailable to a party that would have been an
Indemnitee under any

                                      -14-
<PAGE>

     such Section in respect of any losses, claims, damages or liabilities (or
     actions or proceedings in respect thereof) referred to therein, then each
     party that would have been an indemnifying party thereunder shall, in lieu
     of indemnifying such Indemnitee, contribute to the amount paid or payable
     by such Indemnitee as a result of such losses, claims, damages or
     liabilities (or actions or proceedings in respect thereof) in such
     proportion as is appropriate to reflect the relative fault of such
     indemnifying party on the one hand and such Indemnitee on the other in
     connection with the statements or omissions which resulted in such losses,
     claims, damages or liabilities (or actions or proceedings in respect
     thereof). The relative fault shall be determined by reference to, among
     other things, whether the untrue or alleged untrue statement of a material
     fact or the omission or alleged omission to state a material fact relates
     to information supplied by such indemnifying party or such Indemnitee and
     the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such statement or omission. The parties
     agree that it would not be just or equitable if contribution pursuant to
     this Section 8.5.4 were determined by pro rata allocation or by any other
     method of allocation which does not take account of the equitable
     considerations referred to in the preceding sentence. The amount paid or
     payable by a contributing party as a result of the losses, claims, damages
     or liabilities (or actions or proceedings in respect thereof) referred to
     above in this Section 8.5.4 shall include any legal or other expenses
     reasonably incurred by such Indemnitee in connection with investigating or
     defending any such action or claim. No Person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Securities
     Act) shall be entitled to contribution from any Person who was not guilty
     of such fraudulent misrepresentation.

          8.5.5.  Limitation on Liability of Holders of Registrable Securities.
                  ------------------------------------------------------------
     The liability of each holder of Registrable Securities in respect of any
     indemnification or contribution obligation of such holder arising under
     this Section 8.5 shall not in any event exceed an amount equal to the net
     proceeds to such holder (after deduction of all underwriters' discounts and
     commissions) from the disposition of the Registrable Securities disposed of
     by such holder pursuant to such registration.

9.   TRANSFERS TO OTHER HOLDERS.  Shares Transferred by a holder of Shares to

acquiring holder.
