               AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT

               THIS AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT is made
as of July 1, 2003 (this "Agreement"), by and among HWH Capital Partners, L.P.,
a Delaware limited partnership ("HWH Capital"), HWH Cornhusker Partners, L.P., a
Delaware limited partnership ("HWH Cornhusker" and, together with HWH Capital,
"HWH"), Weston Presidio Capital III, L.P., a Delaware limited partnership
("Buyer 1"), Weston Presidio Capital IV, L.P., a Delaware limited partnership
("Buyer 2"), WPC Entrepreneur Fund, L.P., a Delaware limited partnership ("Buyer
3") and WPC Entrepreneur Fund II, L.P., a Delaware limited partnership ("Buyer
4"), MSD Ventures, L.P., a Delaware limited partnership ("MSD") and NBC
Acquisition Corp., a Delaware corporation (the "Company"). Buyer 1, Buyer 2,
Buyer 3 and Buyer 4 are collectively referred to herein as the "Buyers," and
each, a "Buyer." Unless otherwise provided herein, capitalized terms used herein
are defined in Article IX below.



                                R E C I T A L S:

               A. Concurrently with the execution of the Stock Purchase
Agreement, dated as of July 11, 2002 (the "Stock Purchase Agreement"), among
HWH, certain management stockholders and the Buyers, pursuant to which HWH and
the management stockholders sold to the Buyers an aggregate of 416, 912 shares
of Class A Common Stock, par value $0.01 per share, of the Company, the Company
entered into a Registration Rights Agreement, dated as of July 11, 2002 (the
"Original Registration Rights Agreement");

               B. Pursuant to the terms of the Agreement and Plan of Merger,
dated the date hereof (the "Merger Agreement"), among TheCampusHub.com, Inc.
("CHUB"), Nebraska Book Company, Inc. ("NBC") and the Company, CHUB will merge
with and into NBC, and NBC will be the surviving entity (the "Merger"), and the
stockholders of CHUB, including MSD, will receive shares of Common Stock in
connection with the Merger;

               C. In order to induce MSD to enter into the Merger Agreement, the
Company, HWH and the Buyers desire to amend the Original Registration Rights
Agreement; and

               D. Section 10.09 of the Original Registration Rights Agreement
provides that the Original Registration Rights Agreement may be amended only in
writing signed by HWH, the Buyers and the Company.

               E. The parties hereto desire to supercede and restate in its
entirety the Original Registration Rights Agreement.

<PAGE>

               NOW, THEREFORE, in consideration of the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

                                   ARTICLE I

                  GENERAL; SECURITIES SUBJECT TO THIS AGREEMENT

               1.01 Grant of Rights. The Company hereby grants registration
rights to the Designated Holders upon the terms and conditions set forth in this
Agreement.

               1.02 Registrable Securities. For the purposes of this Agreement,
Registrable Securities held by any Designated Holder will cease to be
Registrable Securities, when (i) a Registration Statement covering such
Registrable Securities has been declared effective under the Securities Act by
the Commission and such Registrable Securities have been disposed of pursuant to
such effective Registration Statement, (ii) (x) the entire amount of the
Registrable Securities held by any Designated Holder may be sold in a single
sale, in the opinion of counsel satisfactory to the Company and such Designated
Holder, each in their reasonable judgment, without any limitation as to volume
pursuant to Rule 144 (or any successor provision then in effect) under the
Securities Act and (y) such Designated Holder owns less than 1% of the
outstanding shares of Common Stock on a fully diluted basis, or (iii) the
Registrable Securities are proposed to be sold or distributed by a Person not
entitled to the registration rights granted by this Agreement.

               1.03 Holders of Registrable Securities. A Person is deemed to be
a holder of Registrable Securities whenever such Person owns of record
Registrable Securities, or holds an option to purchase, or a security
convertible into or exercisable or exchangeable for, Registrable Securities
whether or not such acquisition or conversion has actually been effected. If the
Company receives conflicting instructions, notices or elections from two or more
Persons with respect to the same Registrable Securities, the Company may act
upon the basis of the instructions, notice or election received from the
registered owner of such Registrable Securities. Registrable Securities issuable
upon exercise of an option or upon conversion of another security shall be
deemed outstanding for the purposes of this Agreement.

                                   ARTICLE II

                               DEMAND REGISTRATION

               2.01 Request for Demand Registration. Each of HWH Capital and HWH
Cornhusker may make a written request to the Company to register (the party
making such request, the "Initiating Holders"), and the Company shall register,
under the Securities Act (other than pursuant to a Registration Statement on
Form S-4 or S-8 or any successor thereto) (a "Demand Registration"), the number
of Registrable Securities stated in such request; provided, however, that the
Company shall not be obligated to effect (x) more than three such Demand 2
<PAGE>

               Registrations requested by HWH, it being understood that if HWH
Capital and HWH Cornhusker jointly make a request for a Demand Registration,
such request shall constitute one Demand Registration only, (y) a Demand
Registration if the Initiating Holders, together with the Designated Holders
(other than the Initiating Holders) which have requested to register securities
in such registration pursuant to Section 2.02, propose to sell their Registrable
Securities at an aggregate price (calculated based upon the Market Price of the
Registrable Securities on the date of filing of the Registration Statement with
respect to such Registrable Securities) to the public of less than $5,000,000,
and (z) any such Demand Registration commencing prior to 180 days after the IPO
Effectiveness Date. For purposes of the preceding sentence, two or more
Registration Statements filed in response to one demand shall be counted as one
Demand Registration. If the Board of Directors, in its good faith judgment,
determines that any registration of Registrable Securities should not be made or
continued because it would materially interfere with any material financing,
acquisition, corporate reorganization or merger or other material transaction
involving the Company (a "Valid Business Reason"), the Company may (x) postpone
filing a Registration Statement relating to a Demand Registration until such
Valid Business Reason no longer exists, but in no event for more than 45 days
and (y) in case a Registration Statement has been filed relating to a Demand
Registration, the Company, upon the approval of a majority of the Board of
Directors, may cause such Registration Statement to be withdrawn and its
effectiveness terminated or may postpone amending or supplementing such
Registration Statement (in which case, if the Valid Business Reason no longer
exists or if more 45 days have passed since such withdrawal or postponement, the
Initiating Holders may request a new Demand Registration). The Company shall
give written notice of its determination to postpone or withdraw a Registration
Statement and of the fact that the Valid Business Reason for such postponement
or withdrawal no longer exists, in each case, promptly after the occurrence
thereof. Notwithstanding anything to the contrary contained herein, the Company
may not postpone or withdraw a filing under this Section 2.01 more than once in
any 18 month period. Each request for a Demand Registration by the Initiating
Holders shall state the amount of the Registrable Securities proposed to be sold
and the intended method of disposition thereof.

               2.02 Incidental or "Piggy-Back" Rights with Respect to a Demand
Registration. Each of the Designated Holders (other than Initiating Holders
which have requested a registration under Section 2.01) may offer its
Registrable Securities under any Demand Registration pursuant to this Article
II. Within five days after the receipt of a request for a Demand Registration
from an Initiating Holder, the Company shall (i) give written notice thereof to
all of the Designated Holders (other than Initiating Holders which have
requested a registration under Section 2.01) and (ii) subject to Section 2.05,
include in such registration all of the Registrable Securities held by such
Designated Holders from whom the Company has received a written request for
inclusion therein within 10 days of the receipt by such Designated Holders of
such written notice referred to in clause (i) above. Each such request by such
Designated Holder shall specify the number of Registrable Securities proposed to
be registered. The failure of any Designated Holder to respond within such
10-day period referred to in clause (ii) above shall be deemed to be a waiver of
such Designated Holder's rights under this Section 2.02 with respect to such
Demand Registration. Any Designated Holder may waive its rights under this


                                       3
<PAGE>

               Section 2.02 prior to the expiration of such 10-day period by
giving written notice to the Company, with a copy to the Initiating Holders. If
a Designated Holder sends the Company a written request for inclusion of part or
all of such Designated Holder's Registrable Securities in a registration
(whether pursuant to Article II, III or IV), such Designated Holder shall not be
entitled to withdraw or revoke such request without the prior written consent of
the Company in its sole discretion, unless as a result of facts or circumstances
arising after the date on which such request was made relating to the Company or
to market conditions, such Designated Holder reasonably determines that
participation in such registration would have a material adverse effect on such
Designated Holder, provided that any Designated Holders shall be permitted to
withdraw or revoke such request in any circumstances, without requiring the
consent of the Company or any other party, if any of the Initiating Holders
shall have withdrawn any Registrable Securities from such registration.

               2.03 Effective Demand Registration. The Company shall use its
commercially reasonable efforts to cause any such Demand Registration to become
and remain effective not later than 60 days after it receives a request under
Section 2.01 hereof. A registration shall not constitute a Demand Registration
until it has become effective and remains continuously effective for the lesser
of (i) the period during which all Registrable Securities registered in the
Demand Registration are sold or (ii) 120 days; provided, however, that a
registration shall not constitute a Demand Registration if (x) after such Demand
Registration has become effective, such registration or the related offer, sale
or distribution of Registrable Securities thereunder is interfered with by any
stop order, injunction or other order or requirement of the Commission or other
governmental agency or court for any reason not attributable to the Initiating
Holders and such interference is not thereafter eliminated or (y) the conditions
specified in the underwriting agreement, if any, entered into in connection with
such Demand Registration are not satisfied or waived, other than by reason of a
failure by the Initiating Holder.

               2.04 Expenses. The Company shall pay all Registration Expenses in
connection with a Demand  Registration,  whether or not such Demand Registration
becomes effective.

               2.05 Underwriting Procedures. If the Company or the Initiating
Holders so elect, the Company shall use its commercially reasonable efforts to
cause such Demand Registration to be in the form of a firm commitment
underwritten offering and the managing underwriter or underwriters selected for
such offering shall be the Approved Underwriter selected in accordance with
Section 2.06. In connection with any Demand Registration under this Article II
involving an underwritten offering, none of the Registrable Securities held by
any Designated Holder making a request for inclusion of such Registrable
Securities pursuant to Section 2.02 shall be included in such underwritten
offering unless such Designated Holder accepts the terms of the offering as
agreed upon by the Company, the Initiating Holders and the Approved Underwriter,
and then only in such quantity as set forth below. If the Approved Underwriter
advises the Company that the aggregate amount of such Registrable Securities


                                       4
<PAGE>

requested to be included in such offering is sufficiently large to have a
material adverse effect on the success of such offering, then the Company shall
include in such registration, to the extent of the amount that the Approved
Underwriter believes may be sold without causing such material adverse effect,
first, such number of Registrable Securities of the Initiating Holders and any
Designated Holder participating in the offering pursuant to Section 2.02, which
Registrable Securities shall be allocated pro rata among such Initiating Holders
and Designated Holders, based on the number of Registrable Securities requested
to be included in such offering by each such Initiating Holder and Designated
Holder, second, any other securities of the Company requested by holders thereof
to be included in such registration, which such securities shall be allocated
pro rata among such stockholders, based on the number of the Company's
securities requested to be included in such offering by each such stockholder,
and third, securities offered by the Company for its own account.

               2.06 Selection of Underwriters. If any Demand Registration or S-3
Registration, as the case may be, of Registrable Securities is in the form of an
underwritten offering, the Company shall select and obtain an investment banking
firm of national reputation to act as the managing underwriter of the offering
(the "Approved Underwriter"); provided, however, that the Approved Underwriter,
in any case, shall also be approved by the Initiating Holders or S-3 Initiating
Holders, as the case may be, such approval not to be unreasonably withheld.

                                  ARTICLE III

                     INCIDENTAL OR "PIGGY-BACK" REGISTRATION

               3.01 Request for Incidental Registration. At any time after the
IPO Effectiveness Date, if the Company proposes to file a Registration Statement
under the Securities Act with respect to an offering by the Company for its own
account (other than a Registration Statement on Form S-4 or S-8 or any successor
thereto) or for the account of any stockholder of the Company other than the
Designated Holders, then the Company shall give written notice of such proposed
filing to each of the Designated Holders at least 20 days before the anticipated
filing date, and such notice shall describe the proposed registration and
distribution and offer such Designated Holders the opportunity to register the
number of Registrable Securities as each such Designated Holder may request (an
"Incidental Registration"). The Company shall use its commercially reasonable
efforts (within 20 days of the notice provided for in the preceding sentence) to
cause the managing underwriter or underwriters in the case of a proposed
underwritten offering (the "Company Underwriter") to permit each of the
Designated Holders who have requested in writing to participate in the
Incidental Registration to include its Registrable Securities in such offering
on the same terms and conditions as the securities of the Company or the account
of such other stockholder, as the case may be, included therein. In connection
with any Incidental Registration under this Section 3.01 involving an
underwritten offering, the Company shall not be required to include any
Registrable Securities in such underwritten offering unless the Designated
Holders thereof accept the terms of the underwritten offering as agreed upon


                                       5
<PAGE>

between the Company, such other stockholders, if any, and the Company
Underwriter, and then only in such quantity as set forth below. If the Company
Underwriter determines that the registration of all or part of the securities
that have been requested to be included would materially adversely affect the
success of such offering, then the Company shall be required to include in such
Incidental Registration, to the extent of the amount that the Company
Underwriter believes may be sold without causing such material adverse effect,
first, all of the securities to be offered for the account of the Company,
second, any other securities of the Company requested by the Designated Holders
to be included in such offering, which such securities shall be allocated pro
rata among the Designated Holders participating in the offering, based on the
number of Registrable Securities requested to be included in such offering by
each such Designated Holder, and third, any other securities of the Company
requested by holders thereof to be included in such registration, which such
securities shall be allocated pro rata among such stockholders, based on the
number of the Company's securities requested to be included in such offering by
each such stockholder.

               3.02 Expenses. The Company shall bear all Registration Expenses
in connection with any Incidental Registration pursuant to this Article III,
whether or not such Incidental Registration becomes effective.

                                   ARTICLE IV

                              FORM S-3 REGISTRATION

               4.01 Request for a Form S-3 Registration. Upon the Company
becoming eligible for use of Form S-3 (or any successor form thereto) under the
Securities Act in connection with a public offering of its securities, if the
Company shall receive from HWH (acting jointly) or the Buyers (acting jointly)
(the "S-3 Initiating Holders"), a written request that the Company register,
under the Securities Act on Form S-3 (or any successor form then in effect) (an
"S-3 Registration"), all or a portion of the Registrable Securities owned by
such S-3 Initiating Holders, the Company shall give written notice of such
request to all of the Designated Holders (other than S-3 Initiating Holders
which have requested an S-3 Registration under this Section 4.01) at least 10
days before the anticipated filing date of such Form S-3, and such notice shall
describe the proposed registration and offer such Designated Holders the
opportunity to register the number of Registrable Securities as each such
Designated Holder may request in writing to the Company, given within 10 days
after their receipt from the Company of the written notice of such registration.
With respect to each S-3 Registration, the Company shall, subject to Section
4.02, (i) include in such offering the Registrable Securities of the S-3
Initiating Holders and the Designated Holders (who have requested in writing to
participate in such registration on the same terms and conditions as the
Registrable Securities of the S-3 Initiating Holders included therein) and (ii)
use its commercially reasonable efforts to cause such registration pursuant to
this Section 4.01 to become and remain effective as soon as practicable.

                                       6
<PAGE>

               4.02 Form S-3 Underwriting Procedures. If the S-3 Initiating
Holders so elect, the Company shall use its commercially reasonable efforts to
cause such S-3 Registration pursuant to this Article IV to be in the form of a
firm commitment underwritten offering and the managing underwriter or
underwriters selected for such offering shall be the Approved Underwriter
selected in accordance with Section 2.06. In connection with any S-3
Registration under Section 4.01 involving an underwritten offering, the Company
shall not be required to include any Registrable Securities in such underwritten
offering unless the Designated Holders thereof accept the terms of the
underwritten offering as agreed upon between the Company, the Approved
Underwriter and the S-3 Initiating Holders, and then only in such quantity as
set forth below. If the Approved Underwriter believes that the registration of
all or part of the Registrable Securities which the S-3 Initiating Holders and
the other Designated Holders have requested to be included would materially
adversely affect the success of such public offering, then the Company shall be
required to include in the underwritten offering, to the extent of the amount
that the Approved Underwriter believes may be sold without causing such material
adverse effect, first, such number of Registrable Securities of the S-3
Initiating Holders and any Designated Holder participating in the offering
pursuant to Section 4.01, which such Registrable Securities shall be allocated
pro rata among such S-3 Initiating Holders and Designated Holders, based on the
number of Registrable Securities requested to be included in such offering by
each such S-3 Initiating Holder and Designated Holder, second, any other
securities of the Company requested by holders thereof to be included in such
registration, which such securities shall be allocated pro rata among such
stockholders, based on the number of the Company's securities requested to be
included in such offering by each such stockholder, and third, securities
offered by the Company for its own account.

               4.03 Limitations on Form S-3 Registrations. If the Board of
Directors has a Valid Business Reason, the Company may (x) postpone filing a
Registration Statement relating to a S-3 Registration until such Valid Business
Reason no longer exists, but in no event for more than 45 days following the
request and (y) in case a Registration Statement has been filed relating to a
S-3 Registration, the Company, upon the approval of a majority of the Board of
Directors, may cause such Registration Statement to be withdrawn and its
effectiveness terminated or may postpone amending or supplementing such
Registration Statement (in which case, if the Valid Business Reason no longer
exists or if more than 45 days have passed since such withdrawal or
postponement, the S-3 Initiating Holder may request the prompt amendment or
supplement of such Registration Statement or a new S-3 Registration). The
Company shall give written notice of its determination to postpone or withdraw a
Registration Statement and of the fact that the Valid Business Reason for such
postponement or withdrawal no longer exists, in each case, promptly after the
occurrence thereof. Notwithstanding anything to the contrary contained herein,
the Company may not postpone or withdraw a filing, under either this Article IV
or Section 2.01, due to a Valid Business Reason more than once in any 18-month
period. In addition, the Company shall not be required to effect any
registration pursuant to Section 4.01, (i) within 90 days after the effective
date of any other Registration Statement of the Company (other than a
Registration Statement on Form S-4 or S-8 or any successor thereto), (ii) if


                                       7
<PAGE>

Form S-3 is not available for such offering by the S-3 Initiating Holders, or
(iii) if the S-3 Initiating Holders, together with the Designated Holders (other
than S-3 Initiating Holders which have requested an S-3 Registration under
Section 4.01) registering Registrable Securities in such registration, propose
to sell their Registrable Securities at an aggregate price (calculated based
upon the Market Price of the Registrable Securities on the date of filing of the
Form S-3 with respect to such Registrable Securities) to the public of less than
$5,000,000.

               4.04 Expenses. The Company shall bear all Registration Expenses

requested by the Approved Underwriter or the Company Underwriter, as the case
may be, in the case of an underwritten public offering, and (ii) all of the

outstanding capital stock execute agreements identical to those referred to in
this Section 5.01, each Designated Holder (including the Initiating Holders or
the S-3 Initiating Holders, as the case may be) agrees (x) not to effect any
public sale or distribution of any Registrable Securities or of any securities
convertible into or exchangeable or exercisable for such Registrable Securities,
including a sale pursuant to Rule 144 under the Securities Act, or offer to
sell, contract to sell (including any short sale), grant any option to purchase
or enter into any hedging or similar transaction with the same economic effect
as a sale any Registrable Securities and (y) not to make any request for a
Demand Registration or S-3 Registration under this Agreement, during the period
beginning on the 15th day prior to the expected effective date (as determined by
the Company, which shall notify the Designated Holders of such date in writing)
of such Registration Statement and ending on the 90th day following the actual
effective date of such Registration Statement, or such shorter period, if any,
mutually agreed upon by such Designated Holder and the requesting party (except
as part of such registration). If any Designated Holder of Registrable
Securities subject to the foregoing restrictions, or director, executive officer
or other stockholder, is released from any obligation under any agreement,
arrangement or understanding described in this Section 5.01, to any extent, all
Designated Holders of Registrable Securities subject to the same obligation
shall be released from such obligation, to the same extent as such Designated
Holder, director, executive officer or other stockholder.

               5.02 Restrictions on Public Sale by the Company. The Company
agrees not to effect any public sale or distribution of any of its securities,
or any securities convertible into or exchangeable or exercisable for such

<PAGE>

securities (except pursuant to registrations on Form S-4 or S-8 or any successor

effective date (as determined by the Company) of any Registration Statement in
which the Designated Holders of Registrable Securities are participating and
ending on the earlier of (i) the date on which all Registrable Securities
registered on such Registration Statement are sold and (ii) 90 days after the
actual effective date of such Registration Statement (except as part of such
registration).

                                   ARTICLE VI

                      REGISTRATION PROCEDURES AND EXPENSES

               6.01 Obligations of the Company. Whenever registration of
Registrable Securities has been requested pursuant to Article II, III or IV, the
Company shall use its commercially reasonable efforts to effect the registration
and sale of such Registrable Securities in accordance with the terms of Appendix
A hereto.

               6.02 Registration Expenses. The Company shall pay all expenses
arising from or incident to its performance of, or compliance with, this
Agreement, including (i) Commission, stock exchange and NASD registration and
filing fees, (ii) all fees and expenses incurred in complying with securities or

all printing, messenger and delivery expenses, and (iv) the fees, charges and
expenses of counsel to the Company and of its independent public accountants and

(including any expenses arising from any "cold comfort" letters or any special
audits incident to or required by any registration or qualification), and (v)
the fees and expenses of counsel to the Designated Holders, regardless of
whether such Registration Statement is declared effective. All of the expenses
described in the preceding sentence of this Section 6.02 are referred to herein
as "Registration Expenses." The Designated Holders of Registrable Securities
sold pursuant to a Registration Statement shall bear the expense of any broker's

                                  ARTICLE VII

                          INDEMNIFICATION; CONTRIBUTION

               7.01 Indemnification by the Company. The Company agrees to
indemnify and hold harmless each Designated Holder, its partners, stockholders,
members, directors, officers, Affiliates, employees and each Person who controls
(within the meaning of Section 15 of the Securities Act) such Designated Holder
from and against any and all losses, claims, damages, liabilities and expenses
(including reasonable costs and expenses of legal counsel or otherwise arising
from any investigation, action or proceeding, whether commenced or threatened,
in respect to any of the foregoing) (each, a "Liability" and collectively,
"Liabilities"), arising out of or based upon any (i) untrue, or allegedly


                                       9
<PAGE>

untrue, statement of a material fact contained in any Registration Statement,
prospectus or preliminary prospectus or notification or offering circular (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto), (ii) omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading under the circumstances such statements were made, except
insofar as such Liability arises out of or is based upon any untrue statement or
alleged untrue statement or omission or alleged omission contained in such
Registration Statement, preliminary prospectus or final prospectus in reliance
and in conformity with information concerning such Designated Holder furnished
in writing to the Company by such Designated Holder expressly for use therein,
including the information furnished to the Company pursuant to Section 7.02 or
(iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any state securities law or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities law in
connection with the offering covered by such Registration Statement. The Company
shall also provide customary indemnities to any underwriters of the Registrable
Securities, their officers, directors and employees and each Person who controls
(within the meaning of Section 15 of the Securities Act) such underwriters to
the same extent as provided above with respect to the indemnification of the
Designated Holders of Registrable Securities.

               7.02 Indemnification by Designated Holders. In connection with
any Registration Statement in which a Designated Holder is participating
pursuant to Article II, III or IV, each such Designated Holder shall promptly
furnish to the Company in writing such information with respect to such
Designated Holder as the Company may reasonably request or as may be required by
law for use in connection with any such Registration Statement or prospectus and
all information required to be disclosed in order to make the information
previously furnished to the Company by such Designated Holder not materially
misleading or necessary to cause such Registration Statement not to omit a
material fact with respect to such Designated Holder necessary in order to make
the statements therein not misleading. Each Designated Holder agrees severally
to indemnify and hold harmless the Company, the other Designated Holders who
participate in the Registration Statement, any underwriter retained by the
Company and each Person who controls (within the meaning of Section 15 of the
Securities Act) the Company, the other Designated Holders who participate in the
Registration Statement or such underwriter to the same extent as the foregoing
indemnity from the Company to the Designated Holders (including indemnification
of their respective partners, stockholders, members, directors, officers and
employees), but only to the extent that Liabilities arise out of or are based
upon a statement or alleged statement or an omission or alleged omission that
was made in reliance upon and in conformity with information with respect to
such Designated Holder furnished in writing to the Company by such Designated
Holder expressly for use in such Registration Statement or prospectus, including
the information furnished to the Company pursuant to this Section 7.02;
provided, however, that the total amount to be indemnified by such Designated
Holder pursuant to this Section 7.02 shall be limited to the net proceeds
received by such Designated Holder in the offering to which the Registration
Statement or prospectus relates.

<PAGE>

               7.03 Conduct of Indemnification Proceedings. Any Person entitled
to indemnification or contribution hereunder (the "Indemnified Party") agrees to
give prompt written notice to the indemnifying party (the "Indemnifying Party")
after the receipt by the Indemnified Party of any written notice of the
commencement of any action, suit, proceeding or investigation or threat thereof
made in writing for which the Indemnified Party intends to claim indemnification
or contribution pursuant to this Agreement; provided, however, that the failure
so to notify the Indemnifying Party shall not relieve the Indemnifying Party of
any Liability that it may have to the Indemnified Party hereunder (except to the
extent that the Indemnifying Party is materially prejudiced or otherwise
forfeits substantive rights or defenses by reason of such failure). If notice of
commencement of any such action is given to the Indemnifying Party as provided
in the preceding sentence, the Indemnifying Party shall be entitled to
participate in and, to the extent it may wish, jointly with any other
Indemnifying Party similarly notified, to assume the defense of such action at
its own expense, with counsel chosen by it and reasonably satisfactory to such
Indemnified Party. Each Indemnified Party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be paid by the Indemnified Party
unless (i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying
Party fails to assume the defense of such action with counsel reasonably
satisfactory to the Indemnified Party or (iii) the named parties to any such
action (including any impleaded parties) include both the Indemnifying Party and
the Indemnified Party and such parties have been advised by such counsel that
either (x) representation of such Indemnified Party and the Indemnifying Party
by the same counsel would be inappropriate under applicable standards of
professional conduct or (y) there may be one or more legal defenses available to
the Indemnified Party which are different from or additional to those available
to the Indemnifying Party. In any of such cases, the Indemnifying Party shall
not have the right to assume the defense of such action on behalf of such
Indemnified Party, it being understood, however, that the Indemnifying Party
shall not be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) for all
Indemnified Parties and all such expenses shall be reimbursed as incurred. No
Indemnifying Party shall be liable for any settlement entered into without its
written consent, which consent shall not be unreasonably withheld. No
Indemnifying Party shall, without the consent of such Indemnified Party, effect
any settlement of any pending or threatened proceeding in respect of which such
Indemnified Party is a party and indemnity has been sought hereunder by such
Indemnified Party, unless such settlement includes an unconditional release of
such Indemnified Party from all liability for claims that are the subject matter
of such proceeding. Notwithstanding the foregoing, if at any time an Indemnified
Party shall have requested the Indemnifying Party to reimburse the Indemnified
Party for fees and expenses of counsel as contemplated by this Article VII, the
Indemnifying Party agrees that it shall be liable for any settlement of any
proceeding effected without the Indemnifying Party's written consent if (i) such
settlement is entered into more than 30 business days after receipt by the
Indemnifying Party of the aforesaid request and (ii) the Indemnifying Party
shall not have reimbursed the Indemnified Party in accordance with such request
or contested the reasonableness of such fees and expenses prior to the date of
such settlement.

               7.04 Contribution.

               (a) If the indemnification provided for in this Article VII from
the Indemnifying Party is unavailable to an Indemnified Party hereunder or
insufficient to hold harmless an Indemnified Party in respect of any Liabilities
referred to herein, then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Liabilities in such proportion  as is
appropriate to reflect the relative fault  of  the Indemnifying Party and
Indemnified Party in connection  with  the actions which resulted  in such
Liabilities, as  well as any other relevant equitable considerations.  The
relative fault of such Indemnifying  Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the Liabilities referred to above shall be deemed to include, subject
to the limitations set forth in Sections 7.01, 7.02 and 7.03, any legal or other
fees, charges or expenses reasonably incurred by such party in connection with
any investigation or proceeding; provided that the total amount to be
contributed by any Designated Holder shall be limited to the net proceeds
received by such Designated Holder in the offering. For the avoidance of doubt,
no Designated Holder shall be required to contribute under this Section unless
the Liabilities resulted from or arose out of the information furnished by such
Designated Holder to the Company pursuant to Section 7.02.

               (b) The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 7.04 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 Section 7.04(a).

               (c) 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.

                                  ARTICLE VIII

                                    RULE 144

                 The Company covenants that, from and after the IPO
Effectiveness Date, it shall (a) file any reports required to be filed by it
under the Exchange Act and (b) take such further action as each Designated
Holder may reasonably request (including providing any information necessary to
comply with Rule 144 under the Securities Act), all to the extent required from
time to time to enable such Designated Holder to sell Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (i) Rule 144 under the Securities Act, as such rule may
be amended from time to time, or Regulation S under the Securities Act or (ii)
any similar rules or regulations hereafter adopted by the Commission. The
Company shall, upon the request of any Designated Holder, deliver to such
Designated Holder a written statement as to whether it has complied with such
requirements.

and warrants that it has not previously entered into any agreement granting
registration rights to any Person with respect to any securities of the Company


                                       18

Holders or which rights are otherwise inconsistent with the rights granted in
this Agreement.

be amended or waived only in writing signed by HWH, the Buyers and the Company;
provided, that if any proposed amendment or waiver would have a materially

disproportionate manner with respect to the rights, preferences and privileges
of the other similarly situated parties to this Agreement, the consent of the
MSD Stockholder shall be required. No waiver of any provision hereunder or any
breach or default hereof shall extend to or affect in any way any other

                                   Appendix A

A.   Obligations of the Company. Whenever registration of Registrable Securities
     has been requested pursuant to Article II, III or IV, the Company shall use
     its commercially  reasonable efforts to effect the registration and sale of
     such  Registrable  Securities  in  accordance  with the intended  method of
     distribution thereof as quickly as practicable,  and in connection with any
     such request, the Company shall, as expeditiously as possible:

     1.   prepare and file with the Commission (as promptly as practicable,  but
          in any event not later than 60 days after receipt of a request to file
          a Registration  Statement  with respect to  Registrable  Securities) a
          Registration  Statement  on  any  form  for  which  the  Company  then
          qualifies or which counsel for the Company shall deem  appropriate and
          which  form  shall  be  available  for the  sale  of such  Registrable
          Securities  in  accordance  with the intended  method of  distribution
          thereof,  and cause such  Registration  Statement to become effective;
          provided,  however, that (x) before filing a Registration Statement or
          prospectus or any amendments or supplements thereto, the Company shall
          provide counsel selected by the Designated  Holders holding a majority
          of the Registrable  Securities being  registered in such  registration
          ("Holders'  Counsel") and any other Inspector (as hereinafter defined)
          with an  opportunity  to  review  and  comment  on  such  Registration
          Statement and each prospectus  included therein (and each amendment or
          supplement  thereto) to be filed with the Commission,  subject to such
          documents being under the Company's control, and (y) the Company shall
          notify the Holders' Counsel and each seller of Registrable  Securities
          of any stop order issued or threatened by the  Commission and take all
          reasonable actions required to prevent the entry of such stop order or
          to remove it if entered;

     2.   prepare 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  lesser  of (x) 120 days  (except  in the case of a
          registration  filed  pursuant to Rule 415 of the Securities Act or any
          successor rule or  regulation)  and (y) such shorter period which will
          terminate when all Registrable Securities covered by such Registration
          Statement  have been  sold,  and  comply  with the  provisions  of the
          Securities  Act with  respect  to the  disposition  of all  securities
          covered  by  such   Registration   Statement  during  such  period  in
          accordance  with the intended  methods of  disposition  by the sellers
          thereof set forth in such Registration Statement;

     3.   furnish to each seller of Registrable Securities such number of copies
          of such Registration Statement,  each amendment and supplement thereto
          (in each case  including  all exhibits  thereto),  and the  prospectus
          included in such  Registration  Statement  (including each preliminary
          prospectus)  and  any  prospectus  filed  under  Rule  424  under  the
          Securities Act as each such seller may reasonably  request in order to
          facilitate the disposition of the Registrable Securities owned by such
          seller;
<PAGE>

     4.   register  or  qualify  such  Registrable  Securities  under such other
          securities or "blue sky" laws of such  jurisdictions  as any seller of
          Registrable  Securities may reasonably  request,  and to continue such
          qualification   in  effect  in  such   jurisdiction  for  as  long  as
          permissible pursuant to the laws of such jurisdiction,  or for as long
          as  any  such  seller  requests  or  until  all  of  such  Registrable
          Securities are sold,  whichever is shortest,  and do any and all other
          acts and things  which may be  reasonably  necessary  or  advisable to
          enable  any  such  seller  to  consummate  the   disposition  in  such
          jurisdictions  of the  Registrable  Securities  owned by such  seller;
          provided,  however,  that the  Company  shall not be  required  to (x)
          qualify  generally to do business in any  jurisdiction  where it would
          not  otherwise  be required to qualify but for this  Section  A.4, (y)
          subject itself to taxation in any such jurisdiction, or (z) consent to
          general service of process in any such jurisdiction;

     5.   notify  each  seller  of  Registrable  Securities  at any time  when a
          prospectus  relating  thereto is  required to be  delivered  under the
          Securities  Act,  upon  discovery  that,  or upon the happening of any
          event  as  a  result  of  which,  the  prospectus   included  in  such
          Registration Statement contains 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,   in  light  of  the
          circumstances  under  which they were  made,  not  misleading  and the
          Company  shall  promptly  prepare a  supplement  or  amendment to such
          prospectus  and furnish to each  seller of  Registrable  Securities  a
          reasonable  number of copies of such  supplement to or an amendment of
          such  prospectus  as may be necessary so that,  after  delivery to the
          purchasers of such Registrable  Securities,  such prospectus shall not
          contain an 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,  in light of the  circumstances  under which they
          were made, not misleading;

     6.   enter into and perform customary agreements (including an underwriting
          agreement in customary  form with the Approved  Underwriter or Company
          Underwriter, if any, selected as provided in Article II, III or IV, as
          the  case  may be) and  take  such  other  actions  as are  reasonably
          required in order to expedite or facilitate  the  disposition  of such
          Registrable Securities,  including causing its officers to participate
          in "road  shows"  and  other  information  meetings  organized  by the
          Approved Underwriter or Company Underwriter;

     7.   make  available at  reasonable  times for  inspection by any seller of
          Registrable Securities,  any managing underwriter participating in any
          disposition of such Registrable  Securities pursuant to a Registration
          Statement, Holders' Counsel and any attorney or accountant retained by
          any such seller or any managing  underwriter (each, an "Inspector" and
          collectively,  the  "Inspectors"),  all financial  and other  records,
          pertinent  corporate  documents and  properties of the Company and its
          subsidiaries  (collectively,  the  "Records")  as shall be  reasonably
          necessary   to  enable   them  to   exercise   their   due   diligence

                                       2

          responsibility,   and  cause  the  Company's  and  its   subsidiaries'
          officers,   directors  and  employees,   and  the  independent  public
          accountants  of the  Company,  to supply  all  information  reasonably
          requested by any such Inspector in connection  with such  Registration
          Statement.  Records that the Company determines,  in good faith, to be
          confidential  and which it notifies the  Inspectors  are  confidential
          shall not be disclosed by the  Inspectors  (and the  Inspectors  shall
          confirm  their  agreement  in writing in advance to the Company if the
          Company shall so request) unless (x) the disclosure of such Records is
          necessary,   in  the  Company's  judgment,   to  avoid  or  correct  a
          misstatement  or  omission  in the  Registration  Statement,  (y)  the
          release of such  Records is ordered  pursuant  to a subpoena  or other
          order from a court of competent  jurisdiction  after exhaustion of all
          appeals therefrom, or (z) the information in such Records was known to
          the Inspectors on a non-confidential  basis prior to its disclosure by
          the Company or has been made generally  available to the public.  Each
          seller of Registrable  Securities  agrees that it shall, upon learning
          that  disclosure  of such  Records  is sought in a court of  competent
          jurisdiction, give notice to the Company and allow the Company, at the
          Company's  expense,   to  undertake   appropriate  action  to  prevent
          disclosure of the Records deemed confidential;

     8.   if such sale is pursuant to an  underwritten  offering,  obtain  "cold
          comfort"   letters  dated  the  effective  date  of  the  Registration
          Statement and the date of the closing under the underwriting agreement
          from the Company's  independent  public  accountants in customary form
          and  covering  such matters of the type  customarily  covered by "cold
          comfort" letters as the managing underwriter reasonably requests;

     9.   furnish, at the request of any seller of Registrable Securities on the
          date  such  securities  are  delivered  to the  underwriters  for sale
          pursuant to such  registration  or, if such  securities  are not being
          sold through underwriters, on the date the Registration Statement with
          respect to such securities becomes effective,  an opinion,  dated such
          date,  of counsel  representing  the Company for the  purposes of such
          registration, addressed to the underwriters, if any, and to the seller
          making such  request,  covering such legal matters with respect to the
          registration  in respect of which such  opinion is being  given as the
          underwriters,  if any, and such seller may reasonably  request and are
          customarily included in such opinions;

     10.  comply with all applicable  rules and  regulations of the  Commission,
          and make  available to its  security  holders,  as soon as  reasonably
          practicable  but no later than 15 months after the  effective  date of
          the Registration Statement, an earnings statement covering a period of
          12 months  beginning  after  the  effective  date of the  Registration
          Statement, in a manner which satisfies the provisions of Section 11(a)
          of the Securities Act and Rule 158 thereunder;

     11.  cause all such Registrable  Securities to be listed on each securities
          exchange on which  similar  securities  issued by the Company are then
          listed,   provided  that  the  applicable  listing   requirements  are
          satisfied;
                                       3

     12.  cooperate  with  each  seller  of  Registrable   Securities  and  each
          underwriter  participating  in the  disposition  of  such  Registrable
          Securities and their respective counsel in connection with any filings
          required to be made with the NASD; and

     13.  take all other steps  reasonably  necessary to effect the registration
          of the  Registrable  Securities  contemplated  hereby  and  reasonably
          cooperate  with  the  holders  of  such   Registrable   Securities  to
          facilitate the  disposition of such  Registrable  Securities  pursuant
          thereto.

B.   Seller  Information.  The Company may  require  each seller of  Registrable
     Securities as to which any  registration is being effected to furnish,  and
     such seller shall furnish,  to the Company such information  required to be
     included in such  Registration  Statement by applicable  securities laws or
     otherwise necessary or desirable in connection with the disposition of such
     Registrable  Securities  as the  Company  may from time to time  reasonably
     request  in  writing.  If any  seller of  Registrable  Securities  fails to
     provide  such  information  required to be  included  in such  Registration
     Statement by applicable securities laws or otherwise necessary or desirable
     in connection  with the  disposition  of such  Registrable  Securities in a
     timely manner after written request therefor,  the Company may exclude such
     seller's  Registrable  Securities from a registration under Article II, III
     or IV.

C.   Notice to Discontinue.  Each Designated Holder agrees that, upon receipt of
     any  notice  from the  Company  of the  happening  of any event of the kind
     described  in  Section  A.5,  such   Designated   Holder  shall   forthwith
     discontinue   disposition  of  Registrable   Securities   pursuant  to  the
     Registration  Statement  covering such  Registrable  Securities  until such
     Designated  Holder's  receipt of the copies of the  supplemented or amended
     prospectus  contemplated by Section A.5 and, if so directed by the Company,
     such  Designated  Holder  shall  deliver to the Company  (at the  Company's
     expense)  all  copies,  other  than  permanent  file  copies  then  in such
     Designated Holder's possession, of the prospectus covering such Registrable
     Securities  which is current at the time of receipt of such notice.  If the
     Company  shall give any such  notice,  the Company  shall extend the period
     during which such  Registration  Statement  shall be  maintained  effective
     pursuant to this  Agreement  (including  the period  referred to in Section
     A.2) by the number of days during the period from and including the date of
     the giving of such notice pursuant to Section A.5 to and including the date
     when  sellers  of  such  Registrable  Securities  under  such  Registration
     Statement  shall have  received the copies of the  supplemented  or amended
     prospectus contemplated by and meeting the requirements of Section A.5.
