dividends under the Preferred Stock (assuming all such interest and dividends
were paid in shares of the Common Stock) for all such interest and dividends
assuming a one-year period and (3) the number of shares of the Common Stock
issuable upon conversion in full of warrants described above. Notwithstanding
anything herein contained to the contrary, if the actual number of shares of the

Securities" shall be deemed to include such additional shares of the Common
Stock and the Company shall promptly, but in any case within seven (7) days of
notice of such fact, file one or more additional Registration Statements
covering such additional shares of the Common Stock. The Company shall use its
best efforts to cause such additional Registration Statements to be declared
effective as promptly as possible, but in any event within 60 days after the
date of the notice triggering such requirement.

regulation hereafter adopted by the Commission having substantially the same
effect as such Rule.

and file with the Commission a "Shelf" Registration Statement covering all
Registrable Securities for an offering to be made on a continuous basis pursuant
to Rule 415. The Registration Statement shall be on Form S-3 (except if
otherwise directed by the Holders 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 prior to the
Effectiveness Date, and to keep such Registration Statement continuously
effective under the Securities Act until the date which is three years after the
date that such Registration Statement is declared effective by the Commission or
such earlier date when all Registrable Securities covered by such Registration
Statement have been sold or may be sold without volume restrictions pursuant to
Rule 144 as determined by the counsel to the Company pursuant to a written
opinion letter, addressed to the Holders to such effect (the "Effectiveness
Period"); provided, however, that the Company shall not be deemed to have used
its best efforts to keep the Registration Statement effective during the
Effectiveness Period if it voluntarily takes any action that would result in the
Holders not being able to sell the Registrable Securities covered by such
Registration Statement during the Effectiveness Period, unless such action is
required under applicable law or the Company has filed a post-effective
amendment to the Registration Statement and the Commission has not declared it
effective.

                  (b) If the Holders of a majority of the Registrable Securities
so elect, an offering of Registrable Securities pursuant to the Registration
Statement may be effected 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


                                       -4-

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 or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a majority of the Registrable Securities included in such offering. 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.

by the Holders in connection with an Underwritten Offering hereunder) in
accordance with the method or methods of distribution thereof as specified by
the Holders (except if otherwise directed 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
the filing of the Registration Statement or any related Prospectus or any
amendment or supplement thereto (including any document that would be
incorporated or deemed to be incorporated therein by reference), the Company
shall (i) furnish to the Holders, their Special Counsel and any managing
underwriters, copies of all such documents proposed to be filed, which documents

independent certified public accountants to respond to such inquiries as shall
be necessary, in the opinion of respective counsel to such Holders and such

such Prospectus or any amendments or supplements thereto to which the Holders of
a majority of the Registrable Securities, their Special Counsel, or any managing
underwriters, shall reasonably object within five (5) Business Days of their
receipt thereof.

                  (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

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

                  (d) Use its best efforts to avoid the issuance of, or, if

                  (e) If requested by any managing underwriter or the Holders of
a majority 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, without charge, at least one conformed copy of each

thereto by each of the selling Holders and any underwriters in connection with
the offering and sale of the Registrable Securities covered by such Prospectus
and any amendment or supplement thereto.

fails to furnish such information within a reasonable time after receiving such
request.

                  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 (i) the inclusion therein of language, in form and
substance reasonably satisfactory to such Holder, to the effect that the
ownership by such Holder of such securities is not to be construed as a
recommendation by such Holder of the investment quality of the Company's
securities covered thereby and that such ownership does not imply that such
Holder will assist in meeting any future financial requirements of the Company,
or (ii) 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.

or sell any Registrable Securities under the Registration Statement until it has
received copies of the Prospectus as then amended or supplemented as
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) the Purchaser 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)(iv),
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.

(B) in compliance with


                                      -10-
   11
state securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel for the underwriters or 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 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, (v) fees and disbursements of all
independent certified public accountants referred to in Section 3(l)(iii)
(including, without limitation, the expenses of any special audit and "cold
comfort" letters required by or incident to such performance), (vi) Securities
Act liability insurance, if the Company so desires such insurance, and (vii)
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) In connection with the Registration Statement, the Company
shall reimburse the Holders for the reasonable fees and disbursements of one
firm of attorneys chosen by the Holders of a majority of the Registrable
Securities.

         5.       Indemnification

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement and without limitation as to
time, 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 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


                                      -11-
   12
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, which
information was reasonably relied on by the Company 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.

                  (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 and that such information was
reasonably relied upon by the Company for use in the Registration Statement,
such Prospectus or such form of 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 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


                                      -12-
   13
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 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 of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

                  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 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,


                                      -13-
   14
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 attorneys' or other 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), the Purchaser
shall not be required to contribute, in the aggregate, any amount in excess of
the amount by which the proceeds actually received by the Purchaser from the
sale of the Registrable Securities subject to the Proceeding exceeds the amount
of any damages that the Purchaser 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 Exchange Act in a timely manner and, if at any time the Company is not
required to file such reports, they 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. 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. 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


                                      -14-
   15
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 Inconsistent Agreements. Except as and to the extent
specifically set forth in Schedule 7(b) attached hereto, neither the Company nor
any of its subsidiaries has, as of the date hereof, nor shall the Company or any
of its subsidiaries, 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 in this Agreement or otherwise conflicts with the
provisions hereof. Except and to the extent specifically set forth on Schedule
7(b) attached hereto, neither the Company nor any of its subsidiaries has
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 a majority of
the then 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. 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 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 to each holder of Registrable Securities 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 portion of the Registrable
Securities for to which such holder has requested inclusion hereunder. Any
exclusion of Registrable Securities shall be made pro rata among the holders
seeking to include Registrable Securities,


                                      -15-
   16
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 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 Holders and that does not
directly or indirectly affect the rights of other Holders may be given by
Holders of at least a majority of the 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 given and effective on the earliest of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Section prior to 4:30 p.m. (New
York City time) on a Business Day, (ii) the Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in the Purchase Agreement later than 4:30
p.m. (New York City time) on any date and earlier than 11:59 p.m. (New York City
time) on such date, (iii) the Business Day following the date of mailing, if
sent by nationally recognized overnight courier service, or (iv) upon actual
receipt by the party to whom such notice is required to be given.

            If to any other Person who is then the registered Holder:

                                      To the address of such Holder as it
                                      appears in the stock transfer books or
                                      Debenture Register of the Company

or such other address as may be designated in writing hereafter, in the same
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
the parties and shall inure to the benefit of each Holder. The Company may not
assign its rights or obligations hereunder without the prior written consent of
each Holder. The Purchaser may assign its rights hereunder in the manner and to
the Persons as permitted under the Purchase Agreement.

                  (h) Counterparts. This Agreement may be executed in any number
of counterparts, each of which when so executed shall be deemed to be an
original and, all of which taken together shall constitute one and the same
Agreement. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with
the same force and effect as if such facsimile signature were the original
thereof.

                  (i) Governing Law; Submission to Jurisdiction;. This Agreement
shall be governed by and construed in accordance with the laws of the State of
New York, without regard to principles of conflicts of law. The Company hereby
irrevocably submits to the jurisdiction of any New York state court sitting in
the Borough of Manhattan in the City of


                                      -17-
   18
New York or any federal court sitting in the Borough of Manhattan in the City of
New York (collectively, the "New York") in respect of any Proceeding arising out
of or relating to this Agreement, and irrevocably accepts for itself and in
respect of its property, generally and unconditionally, jurisdiction of the New
York Courts. The Company irrevocably waives to the fullest extent it may
effectively do so under applicable law any objection that it may now or
hereafter have to the laying of the venue of any such Proceeding brought in any
New York Court and any claim that any such Proceeding brought in any New York
Court has been brought in an inconvenient forum. Nothing herein shall affect the
right of any Holder to serve process in any manner permitted by law or to
commence legal proceedings or otherwise proceed against the company in any other
jurisdiction.

                  (j) Cumulative Remedies. The remedies provided herein are
cumulative and not exclusive of any remedies provided by law.

                  (k) 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.

                  (l) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (m) Shares Held by The Company and its Affiliates. Whenever
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.
