   4



the applicable Registrable Securities in accordance herewith or if the Company
is not then eligible to register for resale the Registrable Securities on Form
S-3, in which case such registration shall be on another appropriate form in
accordance herewith). The Company shall (i) not permit any securities other than
the Registrable Securities to be included in the Registration Statement and (ii)
use its best efforts to cause the Registration Statement to be declared
effective under the Securities Act as promptly as possible after the filing
thereof, but in any event shall use its best efforts to cause such Registration

Statement, if the Holders of a majority of the Registrable Securities so elect,
an offering of Registrable Securities may be effected on no more than two
occasions in the form of an Underwritten Offering. In such event, and if the
managing underwriters advise the Company and such Holders in writing that in
their opinion the amount of Registrable Securities proposed to be sold in such
Underwritten Offering exceeds the amount of Registrable Securities which can be
sold in such Underwritten Offering, there shall be included in such Underwritten
Offering the amount of such Registrable Securities which in the opinion of such
managing underwriters can be sold, and such amount shall be allocated pro rata
among the Holders proposing to sell Registrable Securities in such Underwritten
Offering.

                  (c) If any of the Registrable Securities are to be sold in an
Underwritten Offering, the investment banker that will administer the offering
will be selected by the Holders of a majority of the Registrable Securities
included in such offering upon consultation with the Company. No Holder may
participate in any Underwritten Offering hereunder unless such Person (i) agrees
to sell its Registrable Securities on the basis provided in any underwriting
agreements approved by the Persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such arrangements.

applicable Filing Date, a Registration Statement on Form S-3 (or such other form

or if the Company is not then eligible to register for resale the Registrable
Securities on Form S-3, in which case such registration shall be on another
appropriate form in accordance herewith) in accordance with the method or
methods of distribution thereof as specified by the Holders, and cause the
Registration Statement to become effective and remain effective as provided
herein; provided, however, that not less than five (5) Business Days prior to

managing underwriters, and (ii) cause its officers and directors, counsel and
independent certified public accountants to respond to such inquiries as shall
be necessary, in the reasonable opinion of Special Counsel to such Holders and

Statement or any such Prospectus or any amendments or supplements thereto to
which the Holders of a majority of the Registrable Securities covered by such
Registration Statement, their Special Counsel, or any managing underwriters,
shall reasonably object in writing within three (3) Business Days of their
receipt thereof.

                  (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be

register for resale under the Securities Act all of the Registrable Securities;

Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as practicable to any comments
received from the Commission with respect to the Registration Statement or any
amendment thereto and promptly provide the Holders true and complete copies of
all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply with the provisions of the Securities Act and the
Exchange Act with respect to the disposition of all Registrable Securities
covered by the Registration Statement during the applicable period in accordance
with the intended methods of disposition by the Holders thereof set forth in the
Registration Statement as so amended or in such Prospectus as so supplemented.

                  (c) Notify the Holders of Registrable Securities to be sold,
their Special Counsel and any managing underwriters immediately (and, in the
case of (i)(A) below, not less than five (5) days prior to such filing) and (if
requested by any such Person) confirm such notice in writing no later than one
(1) Business Day following the day (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) when the Commission notifies the Company whether there will be
a "review" of such Registration Statement and whenever the Commission comments
in writing on such Registration Statement and (C) with respect to the
Registration Statement or any post-effective amendment, when the same has become
effective; (ii) of any request by the Commission or any other Federal or state
governmental authority for amendments or supplements to the Registration
Statement or Prospectus or for additional information; (iii) of the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) if at any time any of the
representations and warranties of the Company contained in any agreement
(including any underwriting agreement) contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any 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.

                  (d) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                  (e) If requested by any managing underwriter or the Holders of
a majority in interest of the Registrable Securities to be sold in connection
with an Underwritten Offering, (i) promptly incorporate in a Prospectus
supplement or post-effective amendment to the Registration Statement such
information as such managing underwriters and such Holders reasonably agree
should be included therein and (ii) make all required filings of such Prospectus
supplement or such post-effective amendment as soon as practicable after the
Company has received notification of the matters to be incorporated in such
Prospectus supplement or post-effective amendment; provided, however, that the
Company shall not be required to take any action pursuant to this Section 3(e)
that would, in the opinion of counsel for the Company, violate applicable law or
be materially detrimental to the business prospects of the Company.

Holders, any underwriters and their Special Counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as
any Holder or underwriter requests in writing, to keep each such registration or
qualification (or exemption therefrom) effective during the Effectiveness Period
and to do any and all other acts or things necessary or advisable to enable the
disposition in such jurisdictions of the Registrable Securities covered by a
Registration Statement; provided, however, that the Company shall not be
required to qualify generally to do business in any jurisdiction where it is not
then so qualified or to take any action that would subject it to general service
of process in any such jurisdiction where it is not then so subject or subject
the Company to any material tax in any such jurisdiction where it is not then so
subject.

required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.

Agreement.

                  (l) Enter into such agreements (including an underwriting
agreement in form, scope and substance as is customary in Underwritten

facilitate the disposition of such Registrable Securities, and whether or not an

public accountants of any subsidiary of the Company or of any business acquired
by the Company for which financial statements and financial data is, or is
required to be, included in the Registration Statement), addressed to each
selling Holder and each of the underwriters, if any, in form and substance as
are customary in connection with Underwritten Offerings; (iv) if an underwriting
agreement is entered into, the same shall contain indemnification provisions and

Registrable Securities participating in such Underwritten Offering); and (v)
deliver such documents and certificates as may be reasonably requested by the
Holders of a majority of the Registrable Securities being sold, their Special

   9



normally kept, during reasonable business hours, all financial and other
records, pertinent corporate documents and properties of the Company and its
subsidiaries, if any, and cause the officers, directors, agents and employees of
the Company and its subsidiaries, if any, to supply all information in each case
reasonably requested by any such Holder, representative, underwriter, attorney
or accountant in connection with the Registration Statement; provided, however,
that any information that is determined in good faith by the Company in writing

becomes generally available to the public other than as a result of a disclosure

not known by such Person to be bound by a confidentiality agreement with the
Company.

                  (n) Comply with all applicable rules and regulations of the
Commission and make generally available to its security holders earning
statements satisfying the provisions of Section 11(a) of the Securities Act and
Rule 158 not later than 45 days after the end of any 12-month period (or 90 days
after the end of any 12-month period if such period is a fiscal year) (i)
commencing at the end of any fiscal quarter in which Registrable Securities are
sold to underwriters in a firm commitment or best efforts Underwritten Offering
and (ii) if not sold to underwriters in such an offering, commencing on the

                  (o) The Company may require each selling Holder to furnish to
the Company such information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement and the Company may exclude from such registration the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within a reasonable time after receiving such request. The Company shall also
disclose in the Registration Statement such other information regarding each
Holder and its plan of distribution of the Registrable Securities as such Holder
shall reasonably request, except where such inclusion of information would
violate applicable law.

                  If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar Federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  Each Holder by its acquisition of the Registrable Securities
covenants and agrees that (i) such Holder will not offer or sell any Registrable
Securities under the Registration Statement until it has received copies of the
Prospectus as then amended or supplemented as

                                       -9-

   10



contemplated in Section 3(g) and notice from the Company that such Registration
Statement and any post-effective amendments thereto have become effective as
contemplated by Section 3(c) and (ii) such Holder and its officers, directors or
Affiliates, if any, will comply with the prospectus delivery requirements of the
Securities Act as applicable to them in connection with sales of Registrable
Securities pursuant to the Registration Statement.

                  Each Holder agrees by its acquisition of such Registrable
Securities that, upon receipt of a notice from the Company of the occurrence of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities until such Holder's receipt of the copies of the supplemented
Prospectus and/or amended Registration Statement contemplated by Section 3(j),
or until it is advised in writing (the "Advice") by the Company that the use of
the applicable Prospectus may be resumed, and, in either case, has received
copies of any additional or supplemental filings that are incorporated or deemed
to be incorporated by reference in such Prospectus or Registration Statement.

                  If (a) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (b) there is a significant
business opportunity (including but not limited to the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose, then the Company may postpone or suspend filing or
effectiveness of a Registration Statement for a period not to exceed 20
consecutive days, provided that the Company may not postpone or suspend its
obligation under this Section for more than 60 days in the aggregate during any
12 month period; provided, however, that no such postponement of suspension
shall be permitted for consecutive 20 day periods, arising out of the same set
as of facts, circumstances or transactions.

                  4.       Registration Expenses

                  (a) All fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall, except as and to the extent
specified in Section 4(b), be borne by the Company whether or not pursuant to an
Underwritten Offering and whether or not the Registration Statement is filed or
becomes effective and whether or not any Registrable Securities are sold
pursuant to the Registration Statement. The fees and expenses referred to in the
foregoing sentence shall include, without limitation, (i) all registration and
filing fees (including, without limitation, fees and expenses (A) with respect
to filings required to be made with the Nasdaq National Market and each other
securities exchange or market on which Registrable Securities are required
hereunder to be listed and (B) in compliance with state securities or Blue Sky
laws (including, without limitation, fees and disbursements of counsel for the
Holders in connection with Blue Sky qualifications of the Registrable Securities
and determination of the eligibility of the Registrable Securities for
investment under the laws of such jurisdictions as the managing underwriters, if
any, or the Holders of a majority of the

                                      -10-

   11



applicable Registrable Securities may designate)), (ii) printing expenses
(including, without limitation, expenses of printing certificates for
Registrable Securities and of printing prospectuses if the printing of
prospectuses is requested by the managing underwriters, if any, or by the
holders of a majority of the Registrable Securities included in the Registration
Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and
disbursements of counsel for the Company and Special Counsel for the Holders, in
the case of the Special Counsel, to a maximum amount of $5,000, (v) Securities
Act liability insurance, if the Company so desires such insurance, and (vi) fees
and expenses of all other Persons retained by the Company in connection with the
consummation of the transactions contemplated by this Agreement. In addition,
the Company shall be responsible for all of its internal expenses incurred in
connection with the consummation of the transactions contemplated by this
Agreement (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit, the fees and expenses incurred in connection with the listing
of the Registrable Securities on any securities exchange as required hereunder.

                  (b) If the Holders require an Underwritten Offering pursuant
to the terms hereof, the Company shall be responsible for all costs, fees and
expenses in connection therewith, except for the fees and disbursements of the
underwriters (including any underwriting commissions and discounts) and their
legal counsel and accountants (which shall be borne by the Holders). Therefore,
in such circumstances the Holders or the underwriters shall bear the expenses of
the fees and disbursements of any legal counsel or accounting firm retained by
the underwriters in connection with such Underwritten Offering and the costs of
any determination (but not filing) by the underwriters of the eligibility of the
Registrable Securities for investment under the applicable state securities
laws. By way of illustration which is not intended to diminish from the
provisions of Section 4(a), the Holders shall not be responsible for, and the
Company shall be required to pay the fees or disbursements incurred by the
Company (including by its legal counsel and accountants) in connection with, the
preparation and filing of a Registration Statement and related Prospectus for
such offering, the maintenance of such Registration Statement in accordance with
the terms hereof, the listing of the Registrable Securities in accordance with
the requirements hereof, and printing expenses incurred to comply with the
requirements hereof.

         5.       Indemnification

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents (including any underwriters
retained by such Holder in connection with the offer and sale of Registrable
Securities), brokers (including brokers who offer and sell Registrable
Securities as principal as a result of a pledge or any failure to perform under
a margin call of Common Stock), investment advisors and employees of each of
them, each Person who controls any such Holder (within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act) and the officers,
directors, agents and employees of each such controlling Person, to the fullest
extent permitted by applicable law, from and against any and all losses, claims,
damages, liabilities, costs (including, without limitation, costs of preparation

                                      -11-

   12



and attorneys' fees) and expenses (collectively, "Losses"), as incurred, arising
out of or relating to any untrue or alleged untrue statement of a material fact
contained in the Registration Statement, any Prospectus or any form of
prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in light of the circumstances under which they were made)
not misleading, except to the extent, but only to the extent, that such untrue
statements or omissions are based solely upon information regarding such Holder
furnished in writing to the Company by or on behalf of such Holder expressly for
use therein, or to the extent that such information relates to such Holder or
such Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto. The Company shall notify the Holders promptly
of the institution, threat or assertion of any Proceeding of which the Company
is aware in connection with the transactions contemplated by this Agreement, and
provided, however, that, with respect to any untrue statement or alleged untrue
statement or omission or alleged omission made in a preliminary prospectus or
Prospectus, the foregoing indemnity agreement shall not inure to the benefit of
any selling Holder, brokers, investment advisors or employees thereof, from whom
the Person asserting any such Losses purchased the Registrable Securities
concerned, or any Person controlling such Holder, to the extent that any such
Loss results from the fact that a copy of the Prospectus or Prospectus as
amended or supplemented was not sent or given to such Person, if required by the
Securities Act so to have been delivered, at or prior to the written
confirmation of the sale of such Registrable Securities to such Person and the
untrue statement or alleged untrue statement or omission or alleged omission was
corrected in such Prospectus or Prospectus as amended or supplemented, if the
Company had previously furnished copies of such Prospectus or Prospectus as
amended or supplemented to such Holder.

                  (b) Indemnification by Holders. Each Holder shall, severally
and not jointly, indemnify and hold harmless the Company, the directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons, to
the fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in the Registration Statement, any
Prospectus, or any form of prospectus, or arising solely out of or based solely
upon any omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading to the extent, but only to the
extent, that such untrue statement or omission is contained in any information
so furnished in writing by such Holder to the Company specifically for inclusion
in the Registration Statement or such Prospectus or to the extent that such
information relates to such Holder or such Holder's proposed method of
distribution of Registrable Securities and was reviewed and expressly approved
in writing by such Holder expressly for use in the Registration Statement, such
Prospectus or such form of Prospectus. In no event shall the liability of any
selling Holder hereunder be

                                      -12-

   13



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.

                  (c) Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party promptly shall notify the
Person from whom indemnity is sought (the "Indemnifying Party") in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

                  An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; or (2) the Indemnifying Party shall have
failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named parties to any such Proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement or
compromise of, or consent to the entry of any judgment with respect to, any
pending or threatened Proceeding in respect of which any Indemnified Party is a
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such Proceeding and (ii) does not include a
statement as to, or an admission of, fault, culpability or a failure to act by
or on behalf of such Indemnified Party.

                  All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within 10 Business Days of written notice thereof to the Indemnifying
Party (regardless of whether it is ultimately determined that an Indemnified
Party is not entitled to indemnification hereunder; provided, that the
Indemnifying Party may require such Indemnified

                                      -13-

   14



Party to undertake to reimburse all such fees and expenses to the extent it is
finally judicially determined that such Indemnified Party is not entitled to
indemnification hereunder).

                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in
accordance with its terms (by reason of public policy or otherwise), 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 Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses 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 of a material fact,
has been taken or 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, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include, subject to the limitations set forth
in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses
incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(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 the immediately preceding
paragraph. Notwithstanding the provisions of this Section 5(d), no Holder shall
be required to contribute, in the aggregate, any amount in excess of the amount
by which the proceeds actually received by such Holder from the sale of the
Registrable Securities subject to the Proceeding exceeds the amount of any
damages that such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. 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.

                  The indemnity and contribution agreements contained in this
Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties.

         6.       Rule 144

                  The Company shall file the reports required to be filed by it
under the Securities Act and the Exchange Act in a timely manner and, if at any
time the Company is not required to file such reports, the Company will, upon
the request of any Holder, make publicly available other information so long as
necessary to permit sales of its securities pursuant to Rule 144.

                                      -14-

   15



The Company further covenants that it will take such further action as any
Holder may reasonably request, all to the extent required from time to time to
enable such Holder to sell Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144;
provided, however, that the Company shall not be obligated to provide an opinion
to any Holder regarding the sale of Registrable Securities pursuant to
exemptions provided by Rule 144. Upon the request of any Holder, the Company
shall deliver to such Holder a written certification of a duly authorized
officer as to whether it has complied with such requirements.

         7.       Miscellaneous

                  (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

                  (b) No Registration Rights Agreements. Except and to the
extent specifically set forth on Schedule 7(b) attached hereto, the Company has
not previously entered into any agreement granting any registration rights with
respect to any of its securities to any Person. Without limiting the generality
of the foregoing, without the written consent of the Holders of at least 75% of
the then underlying and outstanding Registrable Securities, the Company shall
not grant to any Person the right to request the Company to register any
securities of the Company under the Securities Act unless the rights so granted
are subject in all respects to the prior rights in full of the Holders set forth
herein, and are not otherwise in conflict or inconsistent with the provisions of
this Agreement.

                  (c) No Piggyback on Registrations. Except as and to the extent
specifically set forth on Schedule 7(c) attached hereto, neither the Company nor
any of its security holders (other than the Holders in such capacity pursuant
hereto) may include securities of the Company in the Registration Statement
other than the Registrable Securities, and the Company shall not enter into any
agreement providing any such right to any of its securityholders.

                  (d) Piggy-Back Registrations. If at any time when there is not
an effective Registration Statement the Company shall determine to prepare and
file with the Commission a registration statement relating to an offering for
its own account or the account of others under the Securities Act of any of its
equity securities, other than on Form S-4 or Form S-8 (each as promulgated under
the Securities Act) or their then equivalents relating to equity securities to
be issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, the Company shall send

                                      -15-

   16



to each Holder written notice of such determination and, if within twenty (20)
days after receipt of such notice, any such Holder shall so request in writing,
the Company shall include in such registration statement all or any part of the
Registrable Securities such Holder requests to be registered, except that if, in
connection with any Underwritten Offering for the account of the Company the
managing underwriter(s) thereof shall impose a limitation on the number of
shares of Common Stock which may be included in the registration statement
because, in such underwriter(s)' judgment, such limitation is necessary to
effect an orderly public distribution of securities covered thereby, then the
Company shall be obligated to include in such registration statement only such
limited amount of the Registrable Securities which in the opinion of such
managing underwriter(s) can be sold. Any exclusion of Registrable Securities
shall be made pro rata among the Holders seeking to include Registrable
Securities, in proportion to the number of Registrable Securities sought to be
included by such Holders; provided, however, that the Company shall not exclude
any Registrable Securities unless the Company has first excluded all outstanding
securities the holders of which are not entitled by right to inclusion of
securities in such registration statement; and provided, further, however, that,
after giving effect to the immediately preceding proviso, any exclusion of
Registrable Securities shall be made pro rata with holders of other securities
having the right to include such securities in such registration statement. No
right to registration of Registrable Securities under this Section shall be
construed to limit any registration otherwise required hereunder.

                  (e) 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 same shall be in writing and signed by the Company
and the Holders of at least a majority of the then outstanding Notes, Warrants
and Registrable Securities; provided, however, that, for the purposes of this
sentence, Registrable Securities that are owned, directly or indirectly, by the
Company, or an Affiliate of the Company are not deemed outstanding.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
certain Holders and that does not directly or indirectly affect the rights of
other Holders may be given by Holders of at least 75% of the underlying and
outstanding Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the
immediately preceding sentence.

                  (f) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed delivered (i) upon receipt, when delivered personally; (ii)
when sent by facsimile, upon receipt if received on a Business Day prior to 5:00
p.m. (Central Time), or the first Business Day following such receipt if
received on a Business Day after 5:00 p.m. (Central Time); or (iii) on the
Business Day following the date of depositing with a nationally recognized
overnight express courier service, fully prepaid, in each case properly
addressed to the party to receive the same. The addresses and facsimile numbers
for such communications shall be:

manner, by such Person.

                  (g) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and permitted assigns of each of

rights to assignment shall apply to such Purchaser's (and to subsequent)
successors and assigns.

construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law.

                  (l) Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

the consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than the Purchaser or transferees or successors or assigns
thereof if such Persons are deemed to be Affiliates solely by reason of their
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage.
