Agreement, (ii) the entire amount of then outstanding Registrable Securities may

2.       SHELF REGISTRATION.

         (a) Filing and Effectiveness of Shelf Registration. As soon as
practical after the Closing Date, but in no event later than the 45th day after
the Closing Date, the Company shall file with the SEC a Registration Statement
under the Securities Act for an offering to be made on a continuous basis
pursuant to Rule 415 covering all of the Registrable Securities. The Company
shall use its commercially reasonable efforts to cause the SEC to declare such
Registration Statement to become effective as soon as possible after filing and,
after it has been declared effective, to keep it continuously effective until
the earlier of (i) one year after the SEC declares the Registration Statement
effective (as such period may be extended pursuant to Section 2(b)), (ii) the
date that all of the Registrable Securities covered by such Registration
Statement have been sold and (iii) the date the Registrable Securities cease to
be Registrable Securities (the earliest of such dates being hereinafter referred
to as the "Termination Date").

         (b) Suspension of Effectiveness of Shelf Registration. If after the
Registration Statement has become effective the Company furnishes to the Holders
a certificate signed by the President of the Company that in the good faith
judgment of the Board of Directors of the Company it would be detrimental to the
Company or its stockholders for such Registration Statement to remain effective
as long as such Registration Statement would otherwise be required to remain
effective, because (i) such action would materially interfere with a significant
acquisition, corporate reorganization or other similar transaction involving the
Company, (ii) such action would require disclosure of material information that
the Company has a bona fide business purpose for preserving as confidential or
(iii)(A) disclosure is required in the Registration Statement of financial
information of any person or entity other than the Company or its subsidiaries
and affiliates pursuant to Article 3 or Article II of Regulation S-X under the
Securities Act and (B) any of such required financial information (including
related audit reports and consents of independent accountants) is not available
to the Company after use of commercially reasonable efforts to obtain such
financial information, the Company shall have the right to suspend such
effectiveness for a period of not more than 90 days; provided, however, that the
Company may not exercise this right more than twice; provided, further, however,
that if

                                       2
<PAGE>

the effectiveness of the Registration Statement is suspended pursuant to this
provision, the period of such suspension shall be added to the end of the period
that the Registration Statement would otherwise be required to be effective
under this Agreement so that the aggregate period that the Registration
Statement remains effective equals at least one year.

         (c) Road Show Support of Shelf Registration. The Company shall at its
sole cost and expense make available such officers of the Company as the Holders
and their financial advisor shall reasonably request in writing in advance to
participate in "road show" presentations to potential purchasers of the
Registrable Securities covered thereby. This participation shall include
reasonable assistance in the preparation of materials and attendance at meetings
of a nature as underwriters in an Underwritten Offering would reasonably
require, but in no case shall participation in the actual road show
presentations by officers of the Company exceed an aggregate of fifteen days.

3.       PIGGYBACK REGISTRATION.

         (a) Notice and Issuance. If at any time prior to the Termination Date,
the Company proposes to register any of its equity securities, either for its
own account or the account of a security holder or holders, other than (i) a
registration solely for or in connection with employee benefit or incentive
plans or (ii) pursuant to registrations on Form S-4 or any equivalent or
successor form or otherwise in connection with any exchange offer, merger, sale
of substantially all of the assets or other reorganization or recapitalization
of the Company, but only if a Registration Statement to be filed pursuant to
Section 2(a) hereof covering all of the Registrable Securities has not yet
become effective or shall not be effective at such time, the Company will:

                  (A) promptly give written notice (each, a "Notice of
         Registration") to each Holder of such proposed registration; and

                  (B) include in such registration (and any related
         qualification under blue sky laws or other compliance), and in any
         underwriting related to such registration, the amount the Registrable
         Securities specified in a written request (each, a "Piggyback Notice")
         made by any Holder within 20 days after receipt of the Notice of
         Registration.

         (b) Underwriting. The Company shall select the managing underwriter for
any Underwritten Offering commenced pursuant to the terms of this Agreement,
which in the case of an Underwriten Offering being made pursuant to a
Registration Statement filed pursuant to Section 2(a) shall be reasonably
acceptable to the Holders. If the proposed registration for which the Company
gives a Notice of Registration is an Underwritten Offering, the Company shall so
advise the Holders in the Notice of Registration. In such event, each Holder's
right to participate in the Underwritten Offering shall be conditioned upon such
Holder's participation in the underwriting and the inclusion of such Holder's
Registrable Securities in the Underwritten Offering to the extent provided
herein. No Holder may participate in any Underwritten Offering hereunder unless,
among other thing, such Holder (i) enters into an underwriting agreement in
customary form with the managing underwriter selected by the Company and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents and instruments required under the
terms of such underwriting arrangements.

                                       3
<PAGE>

         (c) Cutback. Notwithstanding any other provision of this Agreement, if
the managing underwriter in any Underwritten Offering determines in good faith
that marketing factors require a limitation on the number of shares to be
included in the Underwritten Offering, the Company shall be required to include
in such offering:

                  (i) first, all of the securities of the Company;

                  (ii) second, up to all of the Registrable Securities to be
         offered for the account of the Holders pursuant to Section 3(a), pro
         rata based on the relative amount of Registrable Securities then held
         by such Persons requesting inclusion in the Underwritten Offering; and

                  (iii) third, up to all of the other securities requested to be
         included in such Underwritten Offering, pro rata based on the relative
         amount of such securities then held by each security holder requesting
         inclusion in the Underwritten Offering.

         If, in the good faith judgment of a Holder, the terms of my
Underwritten Offering differ materially from the customary terms and conditions
for such an Underwritten Offering, such Holder may elect to withdraw therefrom
by written notice to the Company and the managing underwriter. Any Registrable
Securities so withdrawn shall not be transferred in a public distribution by the
applicable Holders prior to 90 days after the effective date for the
registration statement relating to the Underwritten Offering, or such shorter
period of time as the Company or the managing underwriter may require.

         (d) Right to Terminate Registration. The Company may terminate or
withdraw any registration initiated by it pursuant to Section 3(a) prior to the
effectiveness of such registration, whether or not any Holder shall have
requested inclusion of Registrable Securities in such registration; provided
that such termination or withdrawal shall not relieve the Company of its
obligations under Section 2.

4.       HOLD-BACK AGREEMENTS.

         (a) Restrictions on Public Sale by Holders of Registrable Securities.
Each Holder of Registrable Securities covered by a Registration Statement filed
pursuant to Section 2(a) or Section 3(a) hereof agrees, if requested by the
Company or the managing underwriters in an Underwritten Offering, not to effect
any sale or other distribution of equity securities of the Company, including
any sale pursuant to Rule 144 under the Securities Act (except as part of such
Underwritten Offering), during the 30-day period prior to, and during the 90-day
period beginning with, the effectiveness of such Registration Statement, or any
greater time period reasonably requested by the managing underwriters in an
Underwritten Offering, to the extent timely notified in writing by the Company
or the managing underwriters.

         (b) Restrictions on Sale of Equity Securities by the Company. To the
extent timely requested by the managing underwriters in an Underwritten
Offering, the Company agrees not to effect any offer, sale or other distribution
of its equity securities, including a sale pursuant to Regulation D under the
Securities Act, during the 30-day period prior to, and during the 90-day period
beginning with, the effectiveness of a Registration Statement filed under
Section 2(a) (or Section 3(a) if the Company is required to notify Holders of
such Underwritten Offering

                                       4
<PAGE>
pursuant to such Section 3(a)), or any greater time period reasonably requested
by the managing underwriters in an Underwritten Offering (except as part of such
Underwritten Offering or pursuant to registrations on Forms S-4 or S-8 or any
successor forms or otherwise in connection with any exchange offer, merger, sale
of substantially all assets or other reorganization or recapitalization of the
Company or the issuance of securities in connection with employee stock options,
stock awards or other employee benefit plans).

5. REGISTRATION PROCEDURES. In connection with the Company's registration
obligations hereunder and except as otherwise provided herein or permitted
hereunder, the Company will use its commercially reasonable efforts to effect

pursuant thereto the Company will use its commercially reasonable efforts to as

NASD; and cause such Registration Statement to become effective; provided,
however, that before filing a Registration Statement or Prospectus or any
amendments or supplements thereto, the Company will furnish to the Holders of
the Registrable Securities covered by such Registration Statement and the
underwriters, if any, copies of all such documents proposed to be filed, which
documents will be subject to the reasonable review of such Holders and any
underwriters, and the Company will not file any Registration Statement or

Holders of the Registrable Securities covered by such Registration Statement or
any such underwriters shall reasonably object;

<PAGE>
jurisdiction or the initiation or threatening of any proceeding for such
purpose; and (vi) of the happening of any event which makes any statement made
in the Registration Statement, the Prospectus or any document incorporated
therein by reference untrue is any material respect or which requires the making

<PAGE>
         The Company may require each selling Holder of Registrable Securities
to furnish to the Company such information regarding the distribution of such
Registrable Securities as the Company may from time to time request in writing.

         Each Holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 5(j) hereof, such Holder
will forthwith discontinue disposition of its Registrable Securities until such
Holder receives copies of the supplemented or amended Prospectus contemplated by
Section 5(j) hereof, or until it is advised in writing (the "Advice") by the
Company that the use of the Prospectus may be resumed, and receives copies of
any additional or supplemental filings which are incorporated by reference in
the Prospectus, and, if so directed by the Company, such Holder will deliver to
the Company (at the Company's expense) all copies, other than permanent file
copies then in such Holder's possession, of the Prospectus covering such
Registrable Securities current at the time of receipt of such notice. In the
event the Company gives such a notice, the time periods regarding the
maintenance of the effectiveness of any Registration Statement filed pursuant to
Section 2(a) hereof will be extended by the number of days from the date the
Company notifies the applicable Holders pursuant to Section 5(c)(vi) through the
date when each Holder of Registrable Securities covered by such Registration
Statement receives either the copies of the supplemented or amended prospectus
contemplated by Section 5(j) hereof or the Advice.

7.       INDEMNIFICATION AND CONTRIBUTION.

         (a) Indemnification by Company. The Company agrees to indemnify and
hold harmless, to the full extent permitted by law, each Holder, its officers,
directors and employees and each Person who controls such Holder (within the
meaning of the Securities Act) against all losses, claims, costs, damages,
liabilities and expenses (including reasonable costs of investigation and legal
expenses) 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 omission or alleged omission to state therein (in
the case of the Prospectus or preliminary Prospectus, in light of the
circumstances under which they were made) a material fact required to he stated
therein or necessary to make the statements therein not misleading, except
insofar as the same arise out of or are based upon any information furnished in
writing to the Company by any Holder expressly for use therein; provided,
however, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage, liability or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any such preliminary Prospectus or included in a
Registration Statement if (i) any Holder, being obligated to do so, fails to
deliver a copy of the Prospectus prior to or concurrently with the sale of the
Registrable Securities to the Person asserting such loss, claim, damage,
liability or expense after the Company had furnished such Holder with a
sufficient number of copies of the same and (ii) the Prospectus corrected such
untrue statement or omission; and provided, further, however, that the Company
shall not be liable in any such case to the extent that any such loss, claim,
cost, damage, liability or expense arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission in the
Prospectus, if such untrue statement or alleged untrue statement, omission or
alleged omission is corrected in an amendment or supplement to the Prospectus
and the Holder thereafter fails to deliver such Prospectus as so amended or
supplemented prior to or concurrently with the sale of the Registrable
Securities to the Person asserting such loss, claim, damage, liability or
expense after the Company had furnished such Holder with a sufficient number of
copies of the same.

         (b) Indemnification by Holders. In connection with each Registration
Statement, each Holder will furnish to the Company such information and
affidavits as the Company requests for use in connection with any Registration
Statement or Prospectus (or amendment or supplement to either) and agrees to
indemnify and hold harmless, to the full extent permitted by law, the Company,
its directors, officers and employees and each Person who controls the Company
(within the meaning of the Securities Act) against any losses, claims, costs,
damages, liabilities and expenses (including reasonable costs of investigation
and legal expenses) 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 omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein (in the case of the Prospectus or preliminary Prospectus, in light of
the circumstances under which they were made) not misleading, to the extent that
such untrue statement or omission relates to the Holders and is contained in any
information or affidavit so furnished in writing by such Holder to the Company
specifically for inclusion in such

                                       9
<PAGE>
Registration Statement, Prospectus or preliminary Prospectus. In no event shall
the liability of any selling Holder hereunder be greater in amount 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. The
Company shall be entitled to receive indemnities from underwriters, selling
brokers, dealer managers and similar securities industry professionals
participating in the distribution, to the same extent as provided above with
respect to information so furnished in writing by such Persons specifically for
inclusion in any preliminary Prospectus, Prospectus or Registration Statement,
if requested.

         (c) Conduct of Indemnification Proceedings. Any Person entitled to
indemnification hereunder (the "Indemnified Party") will (i) give prompt written
notice to the indemnifying party (the "Indemnifying Party") of any claim with
respect to which it intends to seek indemnification or contribution hereunder
and (ii) permit such Indemnifying Party to assume the defense of such claim with
counsel reasonably satisfactory to the Indemnified Party; provided, however,
that the failure to provide such written notice shall not relieve the
Indemnifying Party of its obligations hereunder except to the extent that such
Indemnifying Party is materially prejudiced or otherwise forfeits substantive
rights or defenses by reason of such failure or any resulting delays; provided,
further, however, that any Indemnified Party shall have the right to employ
separate counsel and to participate in the defense of such claim, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
unless (A) the Indemnifying Party has agreed to pay such fees or expenses, or
(B) the Indemnifying Party fails to assume the defense of such claim and employs
counsel reasonably satisfactory to the Indemnified Party or (C) in the
reasonable judgment of the Indemnified Party, based upon advice of its counsel,
an actual or potential conflict of interest exists between the Indemnified Party
and the Indemnifying Party with respect to such claims (in which case, if the
Indemnified Party notifies the Indemnifying Party in writing that the
Indemnified Party elects to employ separate counsel at the expense of the
Indemnifying Party, the Indemnifying Party shall not have the right to assume
the defense of such claim on behalf of the Indemnified Party). The Indemnifying
Party will not be subject to any liability for any settlement made without its
consent (but such consent will not be unreasonably withheld). No Indemnifying
Party or Indemnified Party will be required to consent to entry of any judgment
or enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability with respect to such claim or litigation. 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 Indemnified Parties with respect to such claim, unless in the
reasonable judgment of any such Indemnified Party a conflict of interest exists
between such Indemnified Party and any other of such Indemnified Parties with
respect to such claim, in which event the Indemnifying Party shall be obligated
to pay the fees and expenses of such additional counsel or counsels.

         (d) Contribution. If for any reason the indemnification provided for in
Section 7(a) or Section 7(b) is unavailable to an Indemnified Party or is
insufficient to hold it harmless as contemplated by Section 7(a) or Section
7(b), then the Indemnifying Party shall contribute to the amount paid or payable
by the Indemnified Party as a result of such loss, claim, damage or liability in
such proportion as is appropriate to reflect not only the relative benefits
received by the Indemnified Party and the Indemnifying Party, but also the
relative fault of the Indemnified Party and the Indemnifying Party, as well as
any other relevant equitable considerations;

                                       10
<PAGE>
provided, however, that no Holder shall be required to contribute an amount
greater than the dollar amount of the net proceeds received by such Holder with
respect to the sale of any Registrable Securities. The parties to this Agreement
agree that it would not be just and equitable if contribution pursuant to this
Section 7(d) were determined by pro rata allocation or by any other method of
allocation that does not take into account the equitable considerations referred
to in this Section 7(d). 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.

         (e) Additional Indemnification and Contribution. In the event of an
Underwritten Offering, the Company and each Holder of Registrable Securities
participating in a registration will provide such additional indemnification and
contribution as is reasonably required by the underwriters and as is customarily
contained in underwriting agreements.

8.       RULE 144.

         The Company covenants that it will file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder or, if the Company is not required to
file such reports, it will, upon the request of the Holders of a majority of the
Registrable Securities make publicly available other information so long as
necessary to permit sales pursuant to Rule 144 under the Securities Act. The
Company further covenants that it will take such further action as the Holders
of a majority of the Registrable Securities may reasonably request, all to the
extent required from time to time to enable the Holders to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (a) Rule 144 under the Securities Act, as such
Rule may be amended from time to time, or (b) any similar or successor rule or
regulation hereafter adopted by the SEC. Upon the request of any Holder of
Registrable Securities, the Company will deliver to such Holder a written
statement as to whether it has complied with such information and requirements.

9.       RESTRICTIONS ON TRANSFER.

         (a) Restrictive Legend. Each certificate representing Restricted
Securities shall be stamped or otherwise imprinted with a legend substantially
in the following form (unless otherwise permitted or unless the Registrable
Securities evidenced by such certificate shall have been registered under the
Securities Act), in addition to any legend required under applicable state
securities laws:

         THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
         INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAWS. SUCH SHARES
         MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF SUCH REGISTRATION
         OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL
         THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT. THE SHARES
         REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER
         PURSUANT TO A

                                       11
<PAGE>
         REGISTRATION RIGHTS AGREEMENT AMONG THE COMPANY AND THE HOLDER OF SUCH
         SHARES, A COPY OF WHICH MAY BE OBTAINED WITHOUT CHARGE FROM THE
         COMPANY.

         Upon request of a Holder of such a certificate, the Company shall
remove the foregoing legend from the certificate or issue to such Holder a new
certificate free of any transfer legend, if, with such request, the Company
receives the opinion referred to in Section 9(b) to the effect that any transfer
by such Holder of Registrable Securities evidenced by such certificate will not
violate the Securities Act and applicable state securities laws, unless any such
transfer legend may be removed pursuant to Rule 144(k), in which case no such
opinion shall be required.

         (b) Notice of Proposed Transfers. The Holder of each certificate
representing Registrable Securities by acceptance thereof agrees to comply in
all respects with the provisions of this Section 9(b). Any Person (other than
another Holder or a Subsidiary or Affiliate of the transferring Holder) to whom
any Holder proposes to transfer Registrable Securities must be a bona fide third
party with sufficient financial resources to purchase such Registrable
Securities, and any such proposed transfer must be on reasonable terms
negotiated on an arm's-length basis. Prior to any proposed transfer of any
Registrable Securities other than transfers in compliance with Rule 144(k)
promulgated under the Securities Act or pursuant to an effective Registration
Statement or to a Holder's Subsidiaries or Affiliates under circumstances
expressly contemplated herein, the Holder thereof shall give written notice
(each, a "Transfer Notice") to the Company of such Holder's intention to effect
such transfer. Each Transfer Notice shall describe the manner and circumstances
of the proposed transfer in sufficient detail (including the identity of the
proposed transferee, the proposed price per share and any other material terms
and conditions of the proposed transfer), and shall be accompanied (except in
transfers in compliance with Rule 144(k) promulgated under the Securities Act or
pursuant to an effective Registration Statement or to a Holder's Subsidiaries or
Affiliates) by a written opinion to the Holder and the Company from legal
counsel and in form and substance reasonably satisfactory to the Company, to the
effect that the proposed transfer of the Registrable Securities may be effected
without registration under the Securities Act, whereupon, subject to the
Company's rights set forth in Section 10, the Holder of such Registrable
Securities shall be entitled to transfer such Registrable Securities in
accordance with the terms of the Transfer Notice. Each certificate evidencing
Registrable Securities transferred as provided above shall bear the restrictive
legend set forth in Section 9(a), except that such certificate shall not bear
such restrictive legend if the opinion of counsel referred to above expressly
indicates that such legend is not required in order to establish compliance with
the Securities Act or if such legend is no longer required pursuant to Rule
144(k).

10.      PURCHASE RIGHT. Prior to the 45th day after the Closing Date, upon
receipt of a Piggyback Request pursuant to Section 3(a) or upon receipt of a
Transfer Notice, the Company may, in its sole discretion, elect to purchase all
of the subject Registrable Securities by written notice (each, a "Purchase
Notice") to all Holders, or the Holder requesting the registration or proposing
the transfer of such Registrable Securities, as the case may be. If the Purchase
Notice is in response to a Piggyback Request or a Transfer Notice, such Purchase
Notice must be delivered within five business days after the date of delivery of
such Piggyback Notice or Transfer Notice, as the case may be. The purchase price
per share of such Registrable Securities shall be (i) the average closing price
of a share of Common Stock as reported on the New York

                                       12
<PAGE>
Stock Exchange composite tape for the 10 trading day period preceding the
closing date of the purchase referred to in this Section 10, in the case of a
purchase other than pursuant to a Transfer Notice, or (ii) the price per share
specified in the Transfer Notice, in the case of a purchase related to such
Transfer Notice. In each case, the closing of any purchase of Registrable
Securities pursuant to this Section 10 shall be consummated no later than 3
business days after the Company delivers the Purchase Notice to the applicable
Holder or Holders, or at such other time as the Company and the applicable
Holder or Holders may agree, and the aggregate purchase price for any such
purchase shall be paid in cash, by wire transfer of immediately available funds,
at any such closing.

11.      TRANSFER OF RIGHTS. The rights granted to Holders pursuant to this
Agreement may not be transferred, conveyed or assigned to any Person without the
prior written consent of the Company, whether pursuant to or in connection with
a transfer of Registrable Securities in accordance with Section 9(b) or
otherwise; provided, however, that any Holder may transfer its Registrable
Securities to any other Holder or Subsidiary or Affiliate of the transferring
Holder in accordance with Section 9(b) and any such transferee Holder or
Subsidiary or Affiliate shall be entitled to exercise the rights afforded to
Holders hereunder with respect to any such validly transferred Registrable
Securities.

12.      MISCELLANEOUS.

         (a) Remedies. Each party to this Agreement, in addition to being
entitled to exercise all rights granted by law, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement.
Each party to this Agreement 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) 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 Holders of at least
a majority of the Registrable Securities.

         (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
