Corporation's initial public offering of Class A Common Stock, Holdings may
request (except as otherwise provided herein) an underwritten registration under
the Securities Act of up to 12% of its Registrable

                                       -2-

<PAGE>

                                                                    Exhibit 10.3


Shares on Form S-1 or Form S-2 or any similar long-form registration statement
("Long-Form Registration") or on Form S-3 or any similar short-form registration
statement ("Short-Form Registration"), if available. Within 10 days after
receipt of any request pursuant to this Section 2(a), the Corporation shall send
notice to the holders of Registrable Shares of such request and the Corporation
will include in such registration all Registrable Shares with respect to which
the Corporation has received written requests for inclusion therein within 21
days after the Corporation's notice has been given for Long Form Registration
and within 21 days after the Corporation's notice has been given for Short Form
Registration. All registrations requested pursuant to this Section 2(a) are
referred to herein as "Demand Registrations". Once the Corporation has become
subject to the reporting requirements of the Securities Exchange Act, the
Corporation will use its best efforts to make Short-Form Registrations available
for the sale of Registrable Shares. The Demand Registrations shall each be an
underwritten public offering, and if the underwriter for marketing or other
reasons requests the inclusion in the registration statement of information that
is not required under the Securities Act to be included in a registration
statement on the applicable form for the Short-Form Registration, the
Corporation will provide such information as may be reasonably requested for
inclusion by the underwriter in the Short-Form Registration.

         (b) Registration Expenses. The Corporation will pay all Registration
Expenses for up to three Demand Registration requested by Holdings pursuant to
Section 2(a) (the "Corporation-Paid Demand Registrations"). A registration will
not count as the Corporation-Paid Demand Registration until and unless it has
become effective.

         (c) Priority on Demand Registrations. Subject to Section 2(e), if the
managing underwriters in a Demand Registration advise the Corporation in writing
that in their opinion the inclusion of the number of Registrable Shares and
other securities requested to be included in such offering creates a substantial
risk that the price per share of Class A Common Stock to be sold in the offering
will be reduced, the Corporation will include in such registration, prior to the
inclusion of any securities which are not Registrable Shares, the number of
Registrable Shares requested to be included which in the opinion of such
underwriters can be sold in such offering without creating such a risk.

                                                                    Exhibit 10.3

         (d) Underwritten Registrations. No Person may participate in any
registration hereunder which is underwritten unless such Person (a) agrees to
sell such Person's Registrable Shares on the basis provided in any underwriting
arrangements approved by the Person or Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements. Holdings will have the right
to select the managing underwriters to administer any offering of Registrable
Shares in which the Corporation does not participate as a seller, subject to the
prior approval of the Corporation, which approval shall not be unreasonably
withheld, and the Corporation will have such right, in its sole discretion, in
any offering in which it does participate as a seller.

         (e) Restrictions on Registrations.

             (i) Notwithstanding the provisions of this Section 2, the
Corporation shall not be obligated to effect any such registration,
qualification or compliance pursuant to this Section 2: (A) if Holdings proposes
to sell Registrable Shares and such other securities (if any) at an aggregate
price to the public of less than five million dollars ($5,000,000); (B) if the
Corporation has, within the six (6) month period preceding the date of such
request, already effected a registration for Holdings pursuant to this Section 2
and such registration has been declared or ordered effective, (D) after the
Corporation has effected three (3) registrations pursuant to this Section 2, and
such registrations have been declared or ordered effective and been maintained
effective as provided herein; or (D) if the Independent Directors determine that
such registration would be contrary to the best interest of the Corporation. The
Independent Directors may consider several factors in making such determination
including stock price performance, equity market conditions and the
Corporation's operating results.

             (ii) The Corporation will not be obligated to effect any Demand
Registration within six (6) months after the effective date of a previous Demand
Registration.

         (f) Right to Terminate Registration. The Corporation shall have the
right to terminate or withdraw any registration initiated by it under this
Section 2 prior to the effectiveness of such registration whether or not
Holdings has elected to include securities in such registration upon
determination by the Independent Directors of Corporation that such registration
would be contrary to the best interest of the Corporation. The Registration
Expenses of such withdrawn registration shall be borne by the Corporation.

     3.  Holdback Agreements.
         -------------------

         (a) Holdings hereby agrees that it shall not offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, lend or
otherwise transfer or dispose of, directly or indirectly, any Common Stock (or
other securities) of the Corporation or enter into any swap, hedging or other
arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of any Common Stock (or other securities) of the
Corporation held by Holdings (other than those included in the registration) for
a period specified by the representative of the underwriters not to exceed one
hundred eighty (180) days following the effective date of a registration
statement of the Corporation filed under the Securities Act; provided that:

                                       -4-

                                                                    Exhibit 10.3

             (i) such agreement shall not apply to any shares of Common Stock
(or other securities) purchased in the initial public offering or purchased in
the open market following the initial public offering; and

             (ii) the executive officers and directors of the Corporation enter
into similar agreements.

         Holdings agrees to execute and deliver such other agreements as may be
reasonably requested by the Corporation or any underwriter which are consistent
with the foregoing or which are necessary to give further effect thereto. In
addition, if requested by the Corporation or the representative or
representatives of the underwriters, Holdings shall provide, within ten (10)
days of such request, such information as may be required by the Corporation or
such representative in connection with the completion of any public offering of
the Corporation's securities pursuant to a registration statement filed under
the Securities Act. The obligations described in this paragraph shall not apply
to a registration relating solely to employee benefit plans on Form S-1 or Form
S-8 or similar forms that may be promulgated in the future, or a registration
relating solely to a transaction on Form S-4 or similar forms that may be
promulgated in the future pursuant to Rule 145 of the Securities Act.

         (b) Nothing herein shall prevent Holdings from making a distribution of
Registrable Shares to its owners, provided that the transferees of such
Registrable Shares agree to be bound by the provisions of this Agreement to the
extent Holdings would be so bound.

     4.  Registration Procedures.
         -----------------------

         (a) Subject to Section 2(a), whenever Holdings has requested that any
Registrable Shares be registered pursuant to the terms of this Agreement, the

thereof, and pursuant thereto the Corporation will as expeditiously as possible:

efforts to cause such registration statement to become effective as soon as

supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and

time as the Registrable Shares registered thereunder have been disposed of in
accordance with the intended methods of disposition by Holdings set forth in
such registration statement, but in no event for a period in excess of 6 months;

             (iii) furnish to Holdings and the underwriters of the securities
being registered such number of copies of such registration statement, each
amendment and supplement thereto, the prospectus included in such registration

Holdings or underwriters may reasonably

                                                                    Exhibit 10.3


request in order to facilitate the disposition of the Registrable Shares owned
by Holdings or the sale of such securities by such underwriters;

             (iv) use its best efforts to register or qualify such Registrable

disposition in such jurisdictions of the Registrable Shares owned by Holdings

generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this subparagraph or (ii) consent to general service
of process in any such jurisdiction);

             (v) use its best efforts to cause all such Registrable Shares to be
listed on each securities exchange on which similar securities issued by the
Corporation are then listed, or if no similar securities issued by the
Corporation are then listed on a securities exchange, either a national
securities exchange or the New York Stock Exchange, as selected by the
Corporation;

             (vi) provide a transfer agent and registrar for all such
Registrable Shares not later than the effective date of such registration
statement;

             (vii) enter into customary agreements (including underwriting
agreements) and take all such other actions as Holdings or the underwriters, if
any, reasonably request in order to expedite or facilitate the disposition of
such Registrable Shares (including, but not limited to, effecting a stock split
or a combination of shares);

             (viii) make available for inspection by Holdings, any underwriter
participating in any disposition pursuant to such registration statement, and
any attorney, accountant or other agent designated by any such seller or
underwriter, all financial and other records, pertinent corporate documents and
properties of the Corporation, and cause the Corporation's officers, directors,
employees and independent accountants to supply all information reasonably
requested by any such seller, underwriter, attorney, accountant or agent in
connection with such registration statement;

connection with the distribution of Registrable Shares by Holdings;

             (xii) prepare and promptly file with the Commission and promptly
notify Holdings of the filing of such amendment or supplement to such

prospectus as may be necessary to correct any statements or omissions if, at the
time when a prospectus relating to such securities is required to be delivered
under the Securities Act, any event shall have occurred as the result of which
any such prospectus or any other prospectus as then in effect would include an
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein, in the light of the circumstances in which they
were made, not misleading;

             (xiii) advise Holdings, promptly after it shall receive notice or
obtain knowledge thereof, of the issuance of any stop order by the Commission
suspending the effectiveness of such registration statement or the initiation or
threatening of any proceeding for such purpose and promptly use all reasonable
efforts to prevent the issuance of any stop order or to obtain its withdrawal if
such stop order should be issued;

             (xiv) in case of a Demand Registration, at least 48 hours, and with
respect to any other registration, as soon as reasonably practicable, prior to
the filing of any registration statement or prospectus or any amendment or
supplement to such registration statement or prospectus, furnish a copy thereof
to Holdings and refrain from filing any such registration statement, prospectus,
amendment or supplement to which counsel selected by Holdings shall have
reasonably objected, unless, in the case of an amendment or supplement, in the
opinion of counsel for the Corporation the filing of such amendment or
supplement is reasonably necessary to protect the Corporation from any material
liabilities under any applicable federal or state law and such filing will not
violate applicable laws; and

             (xv) at the request of Holdings in connection with an underwritten
offering, furnish on the date or dates provided for in the underwriting
agreement: (A) an opinion of counsel, addressed to the underwriters and
Holdings, covering such matters as such underwriters and Holdings may reasonably
request; and (B) a letter or letters from the independent certified public
accountants of the Corporation addressed to the underwriters and Holdings,
covering such matters as such underwriters and Holdings may reasonably request,
in which letters such accountants shall state, without limiting the generality
of the foregoing, that they are independent certified public accountants within
the meaning of the Securities Act and that in the opinion of such accountants
the financial statements and other financial data of the Corporation included in
the registration statement, the prospectus, or any amendment or supplement
thereto comply in all material respects with the applicable accounting
requirements of the Securities Act.

         (b) The Corporation may require Holdings to furnish to the Corporation
such information regarding the distribution of such securities and such other
information relating to Holdings and its ownership of Registrable Shares as the
Corporation may from time to time reasonably request in writing. Holdings agrees
to furnish such information to the Corporation and to cooperate with the
Corporation as reasonably necessary to enable the Corporation to comply with the
provisions of this Agreement.

     5.  Registration Expenses.

     6.  Indemnification.
         ---------------

         (a) The Corporation agrees to indemnify, to the fullest extent
permitted by law, Holdings, its officers and directors and each Person who
controls Holdings (within the meaning of the Securities Act or the Securities
Exchange Act) from and against all losses, claims, damages, liabilities and
expenses (including, but not limited to, attorneys' fees except as limited by
Section 6(c)) arising out of or based upon any untrue or alleged untrue
statement of a material fact contained in any registration statement, prospectus
or preliminary prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading or any violation by the
Corporation of any Federal or state securities laws; provided, however, that the
Corporation will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based on (A) any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to the Corporation by or on behalf of Holdings or any holder of
Registrable Shares or any underwriter specifically for inclusion therein, (B)
use of a registration statement or the related prospectus during a period when
use of such prospectus has been suspended and Holdings has received prior notice
of such suspension, or (C) if Holdings or a holder of Registrable Shares fails
to deliver a prospectus, as them amended or supplemented, provided that the
Corporation shall have delivered such prospectus, as then amended or
supplemented. In connection with an underwritten offering, the Corporation will
indemnify such underwriters, their officers and directors and each Person who
controls such underwriters (within the meaning of the Securities Act or the
Securities Exchange Act) to the same extent as provided above with respect to
the indemnification of Holdings. The reimbursements required by this Section
7(a) will be made by periodic payments during the course of the investigation or
defense, as and when bills are received or expenses incurred.

         (b) In connection with any registration statement in which Holdings is,
and/or holders of Registered Shares are participating, Holdings and/or any such
holder will furnish to the Corporation in writing such information and
affidavits as are required by applicable securities laws or as the Corporation
reasonably requests for use in connection with any such

                                       -8-

                                                                    Exhibit 10.3

registration statement or prospectus and, to the fullest extent permitted by
law, will indemnify the Corporation, its directors and officers and each Person
who controls the Corporation (within the meaning of the Securities Act or the
Securities Exchange Act) from and against any losses, claims, damages,
liabilities and expenses (including, but not limited to, attorneys' fees except
as limited by Section 6(c)) resulting from any untrue statement of a material
fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but only to the extent that such untrue statement or
omission is contained in any information or affidavit so furnished in writing by
Holdings or a holder of Registrable Shares.

         (c) Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

         (d) If the indemnification provided for in this Section is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the fullest extent permitted by applicable law contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability in such proportion as is appropriate to reflect the relative
fault of the indemnifying party on the one hand and of the indemnified party on
the other in connection with the matters that resulted in such loss, claim,
damage or liability, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by a court of law by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact related to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement of omission;
provided, that in no event shall the amounts payable in indemnity or
contribution by Holdings under Section 6 exceed the net proceeds received by
such Holder in the registered offering out of which such indemnification arises.

         (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten pubic offering are in conflict with the
foregoing provisions, the provisions in the underwriting agreement shall
control.

                                       -9-

         (f) The indemnification provided for under this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and will survive the transfer of securities.

     7. Compliance with Rule 144 and Rule 144A. At any time and from time to
time after (a) the Corporation registers a class of securities under Section 12
of the Securities Exchange Act, or (b) the expiration of 90 days following the
close of business on the earlier of such date as the Corporation commences to
file reports under Section 13 or Section 15(d) of the Securities Exchange Act,
the Corporation will (i) forthwith furnish to any holder upon request a written
statement of compliance with the filing requirements of the Commission as set
forth in Rule 144 as such rule may be amended from time to time (ii) make
