3. DEMAND REGISTRATIONS

    (a) TIMING OF DEMAND REGISTRATIONS

         Holders of Registrable Securities constituting at least 51% of the
Registrable Securities then outstanding may request in writing at any time and
from time to time that the Company file a registration statement under the
Securities Act on an appropriate form (which form shall be available for the
sale of the Registrable Securities in accordance with the intended method or
methods of distribution thereof and shall include all financial statements
required by the SEC to be filed therewith) covering the shares of Registrable
Securities that are the subject of such request. Notwithstanding the foregoing,
the Holders of Registrable Securities shall not request that the Company file a
registration statement for the Bridge Securities prior to the Initial Increase
Date. Following such request, the Company shall (i) file with the SEC, as soon
as possible but in any event within thirty (30) days of receipt of such request,
such a Registration Statement covering the Registrable Securities requested to
be included in such registration and (ii) cause such Registration Statement to
be declared effective by the SEC, as soon as possible, but in any event within
ninety (90) days of receipt of such request. The Company shall keep any
Registration Statement required by this Section 3 continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Section 7 hereof and in conformity with the requirements of this Agreement,
the Securities Act and the policies, rules and regulations of the SEC as
announced from time to time, until the earlier of (a) the date on which all
Registrable Securities registered pursuant to such Registration Statement have
been sold pursuant to such Registration Statement and (b) the date on which all
Registrable Securities registered pursuant to such Registration Statement are
eligible for resale under Rule 144(k) promulgated under the Securities Act. If
requested by the

                                       4
<PAGE>

Holders requesting registration of Registrable Securities pursuant to this
Section 3(a), such registration shall provide for resale, from time to time, of
the Registrable Securities on a delayed or continuous basis pursuant to Rule 415
under the Securities Act.

    (b) NUMBER OF DEMAND REGISTRATIONS

         No more than four Demand Registrations pursuant to Section 3(a) shall
provide for underwritten offering (any registration for such offering being
referred to as an "Underwritten Demand Registration"); provided, however, that
any such Registration shall not be counted as one of the four Underwritten
Demand Registrations hereunder unless it becomes effective and is maintained
effective in accordance with the requirements specified in Section 3(a).

    (c) REQUIRED THRESHOLDS

         The Company shall not be obligated to prepare, file and cause to become
effective pursuant to this Section 3 a Registration Statement unless the
proposed aggregate public offering price of the securities to be included in
such Demand Registration is at least $10,000,000 (except for the final Demand
Registration exercised).

    (d) PARTICIPATION

         The Company shall promptly give written notice to all Holders of
Registrable Securities upon receipt of a request for a Demand Registration
pursuant to Section 3(a) above. The Company shall, subject to Section 3(e)
below, include in such Demand Registration such shares of Registrable Securities
for which it has received written requests to register such shares within 20
days after such written notice has been given. No shares of Common Stock or
other securities to be sold by the Company or any holder of shares of Common
Stock or other securities of the Company (other than the Holders) shall be
included in any Registration effected pursuant to this Section 3.

    (e) UNDERWRITER'S CUTBACK

         If the public offering of Registrable Securities is to be underwritten
and, in the good faith judgment of the managing underwriter, the inclusion of
all the Registrable Securities requested to be registered hereunder would
interfere with the successful marketing of a smaller number of such shares of
Registrable Securities, the number of shares of Registrable Securities to be
included in such registration shall be reduced to such smaller number with the
participation in such offering to be pro rata among the Holders of Registrable
Securities requesting such registration, based upon the number of shares of
Registrable Securities owned by such Holders.

    (f) MANAGING UNDERWRITER

         The managing underwriter or underwriters of any underwritten public
offering covered by a Demand Registration shall be selected by the Holders of a
majority of the shares of Registrable Securities to be included in such
registration and shall be reasonably acceptable to the Company. For the purposes
hereof, the parties hereto agree that Salomon Smith Barney shall be an
acceptable underwriter.

                                       5

4. PIGGYBACK REGISTRATIONS

    (a) PARTICIPATION

         Each time the Company decides to file a registration statement under
the Securities Act (other than registrations on Forms S-4 or S-8 or any
successor form thereto, and other than a Demand Registration) covering the offer
and sale by it or any of its security Holders of any of its securities for cash
(other than any Registration Statement filed pursuant to the Other Registration
Rights Agreement) (a "Piggyback Registration"), the Company shall give written
notice thereof to all Holders of outstanding Registrable Securities. The Company
shall include in such Registration Statement such shares of Registrable
Securities for which it has received written requests to register such shares
within 20 days after such written notice has been given. If the Registration
Statement is to cover an underwritten offering, such Registrable Securities
shall be included in the underwriting on the same terms and conditions as the
securities otherwise being sold through the underwriters.

    (b) UNDERWRITER'S CUTBACK

         Subject to the requirements of Section 11 hereof, if in the good faith
judgment of the managing underwriter of such offering the inclusion of all of
the shares of Registrable Securities and any other Common Stock requested to be
registered would interfere with the successful marketing of a smaller number of
such shares, then the number of shares of Registrable Securities and other
Common Stock to be included in the offering shall be reduced to such smaller
number with the participation in such offering to be in the following order of
priority: (i) first, the shares of Common Stock which the Company proposes to
sell for its own account, (ii) second, the shares of Registrable Securities and
the Parity Stock requested to be included in such registration, and (iii) third,
any other shares of Common Stock requested to be included. Any necessary
allocation among the Holders of Registrable Securities and Holders of shares of
Parity Stock shall be pro rata among such Holders based upon the number of
shares of Parity Stock and Registrable Securities owned by such Holders.

    (c) COMPANY CONTROL

         The Company may decline to file a Registration Statement after giving
notice to any Holder pursuant to Section 4(a) above, or withdraw a Registration
Statement filed pursuant to Section 4(a) after filing and after such notice, but
prior to the effectiveness thereof, provided that the Company shall promptly
notify each Holder in writing of any such action and provided further that the
Company shall bear all expenses incurred by such Holder or otherwise in
connection with such withdrawn Registration Statement.

5. HOLD-BACK AGREEMENTS

         Except as required pursuant to the Other Registration Rights Agreement,
the Company agrees not to effect any public sale or distribution of its Equity
Securities during the 30-day period prior to, and during the 120-day period
after, the effective date of each underwritten offering made pursuant to a
Demand Registration or a Piggyback Registration, if so requested in writing by
the managing underwriter of any offering effected pursuant to this Agreement
(except as part of such underwritten offering or pursuant to registrations on
Forms S-4 or S-8).

                                       6
<PAGE>

6. LIQUIDATED DAMAGES

         If (i) the Shelf Registration Statement required by this Agreement is
not filed with the SEC on or prior to the Filing Deadline, (ii) the Shelf
Registration Statement has not been declared effective by the SEC on or prior to
the applicable Effectiveness Deadline, or (iii) the Shelf Registration Statement
required by this Agreement is filed and declared effective but shall thereafter
cease to be effective or fail to be usable for its intended purpose without
being succeeded within 2 days by a post-effective amendment to the Shelf
Registration Statement that cures such failure and that is itself declared
effective within 5 days of filing such post-effective amendment to the Shelf
Registration Statement (each such event referred to in clauses (i) through
(iii), a "Registration Default"), then the Company hereby agrees to pay to each
Holder of Bridge Securities affected thereby liquidated damages in an amount
equal to $0.50 per week per $1,000 liquidation preference of the Bridge
Preferred Stock and/or Mezzanine Preferred Stock held by such Holder for each
week or portion thereof that the Registration Default continues for the first
90-day period immediately following the occurrence of such Registration Default.
The amount of the liquidated damages shall increase by an additional $0.25 per
week per $1,000 liquidation preference of the Bridge Preferred Stock and/or
Mezzanine Preferred Stock with respect to each subsequent 90-day period until
all Registration Defaults have been cured, up to a maximum amount of liquidated
damages of $2.50 per week per $1,000 liquidation preference of the Bridge
Preferred Stock and/or Mezzanine Preferred Stock; provided that the Company
shall in no event be required to pay liquidated damages for more than one
Registration Default at any given time. Notwithstanding anything to the contrary
set forth herein, (1) upon filing of the Shelf Registration Statement, in the
case of (i) above, (2) upon the effectiveness of the Shelf Registration
Statement, in the case of (ii) above, (3) upon the filing of a post-effective
amendment to the Shelf Registration Statement or an additional Registration
Statement that causes the Shelf Registration Statement to again be declared
effective or made usable in the case of (iii) above, the liquidated damages
payable with respect to the Registrable Securities as a result of such clause
(i), (ii) or (iii), as applicable, shall cease.

         All accrued liquidated damages shall be paid to the Holders entitled
thereto, in cash on each Dividend Payment Date (as defined in the Bridge
Preferred Stock Certificate of Designations or the Preferred Stock Certificate
of Designations, as applicable). Notwithstanding the fact that any securities
for which liquidated damages are due cease to be Registrable Securities, all
obligations of the Company to pay liquidated damages with respect to securities
shall survive until such time as such obligations with respect to such
securities shall have been satisfied in full.

7. REGISTRATION PROCEDURES

         In connection with any Registration Statement and any related
Prospectus required by this Agreement, the Company shall:

         (a) prepare and file with the SEC as soon as practicable a Registration
Statement with respect to such Registrable Securities and use its commercially
reasonable efforts to keep such Registration Statement continuously effective

     amendment has been filed, and, with respect to the Registration Statement
     or any post-effective amendment, when the same has become effective,

               (2) of any request by the SEC for amendments or supplements to
     the Registration Statement or the Prospectus or for additional information,

     effectiveness of the Registration Statement or the initiation of any
     proceedings for that purpose,

     Securities for sale in any jurisdiction or the initiation or threatening of
     any proceeding for such purpose, and

subject it to general service of process in any such jurisdiction where it is
not then so subject;

         (j) cooperate with the selling Holders of Registrable Securities and

or authorities as may be necessary to enable the seller or sellers thereof or
the underwriters, if any, to consummate the disposition of such Registrable
Securities;

         (l) if the Registration Statement or the Prospectus contains a
Misstatement, prepare a supplement or post-effective amendment to the
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities, the Prospectus will
not contain a Misstatement;

         (m) cause all Registrable Securities covered by the Registration
Statement to be listed on the New York Stock Exchange;

         (n) provide a CUSIP number for all Registrable Securities not later

     primary underwritten offerings;

               (2) obtain opinions of counsel to the Company and updates thereof
     (which counsel and opinions (in form, scope and substance) shall be

     Holders of a majority of the Registrable Securities being sold) addressed
     to each selling Holder and the underwriter, if any, covering the matters
     customarily covered in opinions delivered to underwriters in primary
     underwritten offerings and such other matters as may be reasonably
     requested by such Holders or underwriters;

               (3) obtain comfort letters and updates thereof from the Company's
     independent certified public accountants addressed to the selling Holders
     of Registrable Securities registered thereunder and the underwriters, if

               (4) deliver such documents and certificates as may be reasonably

employees to supply all relevant information, reasonably requested by any such
selling Holder, underwriter, attorney or accountant in connection with the
Registration as is customary for similar due diligence examinations during

offering, (y) beginning with the first month of the Company's first fiscal
quarter commencing after the effective date of the Registration Statement, which
statements shall cover said 12-month periods.

         Notwithstanding anything set forth in this Agreement, the Company shall

Statement pursuant to this Agreement and to suspend the effectiveness of any
such Registration Statement for a reasonable period of time (not exceeding
thirty (30) days) if the Company furnishes to the selling Holders a certificate
signed by the Chairman of the Board or the President of the Company stating that
the Company has determined in good faith that effecting such registration or
offering at such time would adversely affect a material financing, acquisition
or disposition of assets, distribution rights or stock, merger or other
comparable transaction or would require the Company to make public disclosure of
information the public disclosure of which would have a material adverse effect
upon the Company.

8. REGISTRATION EXPENSES

         (a) All expenses incurred in connection with the Company's performance
of or compliance with this Agreement will be borne by the Company (other than
underwriting discounts or commissions), regardless of whether a Registration
Statement becomes effective, including without limitation: (i) all registration
and filing fees and expenses; (ii) all fees and expenses of

                                       11
<PAGE>

compliance with federal securities and state Blue Sky or securities laws; (iii)
all expenses of printing, messenger and delivery services and telephone; (iv)
all fees and disbursements of one counsel for the Company and one counsel for
the Holders of Registrable Securities; (v) all application and filing fees in
connection with listing the Registrable Securities on the New York Stock
Exchange pursuant to the requirements hereof; and (vi) all fees and
disbursements of independent certified public accountants of the Company
(including the expenses of any special audit and comfort letters required by or
incident to such performance).

         The Company will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Company.

         (b) In connection with any Registration Statement required by this
Agreement, the Company will reimburse the Holders of Registrable Securities for
the reasonable fees and disbursements of not more than one counsel.

         Notwithstanding the foregoing, the Company shall not have any
obligation whatsoever in respect of any underwriters' discounts or commissions,
brokerage commissions, dealers' selling concessions, transfer taxes or except as
otherwise expressly set forth herein.

9. INDEMNIFICATION

    (a) INDEMNIFICATION BY COMPANY

         The Company agrees to indemnify and hold harmless each Indemnified
Holder from and against all Claims arising out of or based upon any Misstatement
or alleged Misstatement, except insofar as such Misstatement or alleged
Misstatement was based upon or reliance upon information furnished in writing to
the Company by such Indemnified Holder expressly for use in the document
containing such Misstatement or alleged Misstatement. This indemnity shall not
be exclusive and shall be in addition to any liability which the Company may
otherwise have.

         The foregoing notwithstanding, the Company shall not be liable to the
extent that any such Claim arises out of or is based upon a Misstatement or
alleged Misstatement made in any preliminary prospectus if (i) such Indemnified
Holder failed to send or deliver a copy of the Prospectus with or prior to the
delivery of written confirmation of the sale of Registrable Securities giving
rise to such Claim and (ii) the Prospectus would have corrected such untrue
statement or omission.

         In addition, the Company shall not be liable to the extent that any
such Claim arises out of or is based upon a Misstatement or alleged Misstatement
in a Prospectus, (x) if such Misstatement or alleged Misstatement is corrected
in an amendment or supplement to such Prospectus and (y) having previously been
furnished by or on behalf of the Company with copies of the Prospectus as so
amended or supplemented, such Indemnified Holder thereafter fails to deliver
such Prospectus as so amended or supplemented prior to or concurrently with the
sale to the person who purchased a Registrable Security from such Indemnified
Holder and who is asserting such Claim.

                                       12
<PAGE>

    (b)      INDEMNIFICATION PROCEDURES

         If any action or proceeding (including any governmental investigation
or inquiry) shall be brought or asserted against an Indemnified Holder in
respect of which indemnity may be sought from the Company, such Indemnified
Holder shall promptly notify the Company in writing, and the Company shall
assume the defense thereof, including the employment of counsel satisfactory to
such Indemnified Holder and the payment of all expenses.

         Such Indemnified Holder shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such separate counsel shall be the expense of such Indemnified
Holder unless (i) the Company has agreed to pay such fees and expenses, (ii) the
Company shall have failed to assume the defense of such action or proceeding or
has failed to employ counsel reasonably satisfactory to such Indemnified Holder
in any such action or proceeding or (iii) the named parties to any such action
or proceeding (including any impleaded parties) include both such Indemnified
Holder and the Company, and such Indemnified Holder shall have been advised by
counsel that there may be one or more legal defenses available to such
Indemnified Holder that are different from or additional to those available to
the Company.

         If such Indemnified Holder notifies the Company in writing that it
elects to employ separate counsel at the expense of the Company as permitted by
the provisions of the preceding paragraph, the Company shall not have the right
to assume the defense of such action or proceeding on behalf of such Indemnified
Holder. The foregoing notwithstanding, the Company shall not be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for such Indemnified Holder and any other Indemnified Holders (which firm
shall be designated in writing by such Indemnified Holders) in connection with
any one such action or proceeding or separate but substantially similar or
related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances.

         The Company shall not be liable for any settlement of any such action
or proceeding effected without its written consent, but if settled with its
written consent, or if there be a final judgment for the plaintiff in any such
action or proceeding, the Company agrees to indemnify and hold harmless such
Indemnified Holders from and against any loss or liability by reason of such
settlement or judgment to the extent such Indemnified Holder is entitled to
indemnification under Section 9(a).

    (c) INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES.

         Each Holder of Registrable Securities agrees to indemnify and hold
harmless the Company, its directors and officers and each Person, if any, who
controls the Company within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act to the same extent as the foregoing
indemnity from the Company to such Holder, but only with respect to information
relating to such Holder furnished in writing by such Holder expressly for use in
any Registration Statement, Prospectus or preliminary prospectus. In no event,
however, shall the liability hereunder of any selling Holder of Registrable
Securities be greater than the dollar amount of the net proceeds received by
such Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation.

                                       13
<PAGE>

         In case any action or proceeding shall be brought against the Company
or its directors or officers or any such controlling person, in respect of which
indemnity may be sought against a Holder of Registrable Securities, such Holder
shall have the rights and duties given the Company and the Company or its
directors or officers or such controlling person shall have the rights and
duties given to each Holder by Sections 9(a) and 9(b) above.

    (d) CONTRIBUTION

         If the indemnification provided for in this Section 9 is unavailable to
an indemnified party under Section 9(a) or Section 9(c) above (other than by
reason of exceptions provided in those Sections) in respect of any Claims
referred to in such Sections, then each applicable 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 Claims in such proportion
as is appropriate to reflect the relative fault of the Company on the one hand
and of the Indemnified Holder on the other in connection with the statements or
omissions which resulted in such Claims as well as any other relevant equitable
considerations. The amount paid or payable by a party as a result of the Claims
referred to above shall be deemed to include, subject to the limitations set
forth in Section 9(b), any legal or other fees or expenses reasonably incurred
by such party in connection with investigating or defending any action or claim.

         The relative fault of the Company on the one hand and of the
Indemnified Holder on the other shall be determined by reference to, among other
things, whether the Misstatement or alleged Misstatement relates to information
supplied by the Company or by the Indemnified Holder and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such Misstatement or alleged Misstatement.

         The Company and each Holder of Registrable Securities agree that it
would not be just and equitable if contribution pursuant to this Section 9(d)
were determined by pro rata allocation or by any other method of allocation
which does not take account of the equitable considerations referred to above.

         Notwithstanding the provisions of this Section 9(d), an Indemnified
Holder shall not be required to contribute any amount in excess of the amount by
which (i) the total price at which the securities that were sold by such
Indemnified Holder and distributed to the public were offered to the public
exceeds (ii) the amount of any damages which such Indemnified Holder has
otherwise been required to pay by reason of such Misstatement.

         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.

10. EXCHANGE ACT REPORTING REQUIREMENTS

         From and after the date hereof, the Company shall timely file such
information, documents and reports as the SEC may require or prescribe under
Section 13 or 15(d) (whichever is applicable) of the Exchange Act by all Persons
to which such requirements are applicable (whether or not such requirements are
applicable to the Company. In addition, the Company shall take such other
measures and file such other information, documents and reports, as shall
hereafter be

                                       14
<PAGE>

required by the SEC as a condition to the availability of Rule 144 under the
Securities Act (or any successor provision) and the use of Form S-3.

         From and after the date hereof, the Company shall forthwith upon
request furnish any Holder of Registrable Securities (i) a written statement by
the Company that it has complied with such reporting requirements, (ii) a copy
of the most recent annual or quarterly report of the Company, and (iii) such
other reports and documents filed by the Company with the SEC as such Holder may
reasonably request in availing itself of an exemption for the sale of
Registrable Securities without registration under the Securities Act.

         The purpose of the foregoing requirements are (x) to enable any such
Holder to comply with the current public information requirements contained in
paragraph (c) of Rule 144 under the Securities Act (or any successor provision)
and (y) to qualify the Company for the continued use of registration statements
on Form S-3.

11. REQUIREMENTS FOR PARTICIPATION IN UNDERWRITTEN OFFERINGS

         No Person may participate in any underwritten offering pursuant to a
Registration hereunder unless such Person (a) agrees to sell such Person's
Registrable Securities on the basis provided in any underwriting arrangements
approved by the 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.

12. FUTURE REGISTRATION RIGHTS AGREEMENTS

         Except for an underwriting agreement between the Company and one or
more professional underwriters of securities, the Company shall not agree to
register any Equity Securities under the Securities Act unless such agreement
specifically provides that:

         (a) the Holder of such Equity Securities may not participate in any
Demand Registration without the consent of the Holders of a majority of the
shares of the Registrable Securities included in such registration.

         (b) the Holder of such Equity Securities may not participate in any
Piggyback Registration if the sale of Registrable Securities is to be
underwritten unless, if the managing underwriter limits the total number of
shares to be sold, the Holders of such Equity Securities and the Holders of
Registrable Securities are entitled to participate in such underwritten
distribution based on the order of priority set forth in Section 3 hereof; and

         (c) all Equity Securities excluded from any Registration as a result of
the foregoing limitations may not be publicly offered or sold for a period (not
to exceed at least 30 days prior to the effective date and 120 days thereafter)
that the managing underwriter reasonably determines is necessary in order to
effect the underwritten public offering of Registrable Securities registered
pursuant to this Agreement.

13. MISCELLANEOUS

    (a) REMEDIES

         Each Holder of Registrable Securities, in addition to being entitled to
exercise all rights provided herein, in the Purchase Agreement and granted by
law, including recovery of damages, shall be entitled to specific performance of
its rights under this Agreement. The Company agrees that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it
of the provisions of this Agreement and hereby agrees to waive the defense in
any action for specific performance that a remedy at law would be adequate.

    (b) NO INCONSISTENT AGREEMENTS

         The Company shall not on or after the date of this Agreement enter into
any agreement with respect to its securities that is inconsistent with the
rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof.

         Except for the Other Registration Rights Agreement, the Company has not
previously entered into any agreement with respect to its securities granting
any registration rights to any Person. The rights granted to the Holders of
Registrable Securities hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the Holders of the Company's securities
under any such agreements.

    (c) AMENDMENTS AND WAIVERS

         The provisions of this Agreement, including the provisions of this
sentence, may not be amended, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given unless the Company has
obtained the written consent of the Holders of at least a majority of the
outstanding shares of Registrable Securities. The foregoing notwithstanding, a
waiver or consent to departure from the provisions hereof that relates
exclusively to the rights of Holders of shares of Registrable Securities whose
shares are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect the rights of other Holders of shares of
Registrable Securities may be given by the Holders of a majority of the shares
of Registrable Securities being sold.
