on or after the First Release Date, the holders of a majority in interest of the
Unit Shares, the Warrants and the Warrant Shares collectively, may make a
written demand for registration under the Securities Act of all or part of their
Registrable Securities (a "Demand Registration"). At any time and from time to
time on or after the Second Release Date, the holders of a majority in interest
of the Initial Investor Shares may request a Demand Registration for all or part
of their Registrable Securities. Any demand for a Demand Registration shall
specify the number of shares of Registrable Securities proposed to be sold and

holders of Registrable Securities of a requested Demand Registration, and each
holder of Registrable Securities who wishes to include all or a portion of such
holder's Registrable Securities in the Demand Registration (each such holder
including shares of Registrable Securities in such registration, a "Demanding
Holder") shall so notify the Company within fifteen (15) days after the receipt
by the holder of the notice from the Company. Upon any such request, the
Demanding Holders shall be entitled to have their Registrable Securities
included in the Demand Registration, subject to Section 2.1.4 and the provisos
set forth in Section 3.1.1. The Company shall not be obligated to effect more
than an aggregate of on (1) Demand Registration at the request of the holders of
the Unit Shares, the Warrants and the Warrant Shares, collectively two (2)
Demand Registrations at the request of the holders of the Initial Investor
Shares, in each case, under this Section 2.1.1 in respect of Registrable
Securities. Notwithstanding anything to the contrary contained herein, the
Company shall not be required to seek to cause a Registration Statement with
respect to a Demand Registration to become effective pursuant to this Section
2.1: (A) within a period of ninety (90) days after the effective date of a
Registration Statement filed by the Company; provided, that the Company shall
use commercially reasonable efforts to cause a Demand Registration requested
hereunder to be declared effective promptly following such period if such a
request is made during such period; or (B) if the Company shall furnish to the
Demanding Holder or Holders, a certificate signed by the Chief Executive Officer
of the Company stating that in the good faith judgment of the Board of Directors
of the Company, the filing of a Registration Statement would, at such time,
materially and adversely affect (i) the financial condition of the Company, in
view of a requirement to disclose material non-public information relating to
the Company, which the Company has a bona fide business purpose for preserving
as confidential or (ii) an existing continuing negotiation relating to an
acquisition, disposition, corporate reorganization, private securities offering,
financing or similar transaction with respect to the Company, then the Company
shall have the right to defer such filing for a period of no more than ninety
(90) days; provided, however that the Company may not exercise this right more
than once during any period of twelve (12) consecutive months.


                                        4



            2.1.2.  Effective Registration. A registration will not count as a
Demand Registration until the Registration Statement filed with the Commission
with respect to such Demand Registration has been declared effective and the
Company has complied with all of its obligations under this Agreement with
respect thereto; provided, however, that if, after such Registration Statement
has been declared effective, the offering of Registrable Securities pursuant to
a Demand Registration is interfered with by any stop order or injunction of the
Commission or any other governmental agency or court, the Registration Statement
with respect to such Demand Registration will be deemed not to have been
declared effective, unless and until, (i) such stop order or injunction is
removed, rescinded or otherwise terminated, and (ii) a majority in interest of
the Demanding Holders thereafter elect to continue the offering.

            2.1.3.  Underwritten Offering. If a majority in interest of the
Demanding Holders so elect and such holders so advise the Company as part of
their written demand for a Demand Registration, the offering of such Registrable
Securities pursuant to such Demand Registration shall be in the form of an
underwritten offering. In such event, the Company shall have the right (subject
to the reasonable approval of a majority in interest of the Demanding Holders)
to select the Underwriter(s) for such offering. All Demanding Holders proposing
to distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the Underwriter or Underwriters
selected for such underwriting.

            2.1.4.  Reduction of Offering. If the managing Underwriter or
Underwriters for a Demand Registration that is to be an underwritten offering
advises the Company and the Demanding Holders in writing that the dollar amount
or number of shares of Registrable Securities which the Demanding Holders desire
to sell, taken together with all other shares of Common Stock or other
securities which the Company desires to sell and the shares of Common Stock or
other securities, if any, as to which registration has been requested pursuant
to written contractual piggy-back registration rights held by other shareholders
of the Company who desire to sell, exceeds the maximum dollar amount or maximum
number of shares that can be sold in such offering without adversely affecting
the proposed offering price, the timing, the distribution method, or the
probability of success of such offering (such maximum dollar amount or maximum
number of shares, as applicable, the "Maximum Number of Shares"), then the
Company shall include in such registration: (i) first, the Registrable
Securities as to which Demand Registration has been requested (all pro rata in
accordance with the number of shares that each such person has requested be
included in such registration, regardless of the number of shares held by each
such person (such proportion is referred to herein as "Pro Rata")) that can be
sold without exceeding the Maximum Number of Shares; (ii) second, to the extent
that the Maximum Number of Shares has not been reached under the foregoing
clause (i), all shares of Common Stock or other securities that the Company
desires to sell and that can be sold without exceeding the Maximum Number of
Shares; and (iii) third, to the extent that the Maximum Number of Shares has not
been reached under the foregoing clauses (i) and (ii), the shares of the account
of other persons, including without limitation any Purchase Option Securities,
that the Company is obligated to register pursuant to written contractual
arrangements with other persons and that can be sold without exceeding the
Maximum Number of Shares.

            2.1.5.  Withdrawal. If a majority in interest of the Demanding
Holders disapprove of the terms of any underwriting or are not entitled to
include all of their Registrable Securities in any underwritten offering, such
majority in interest of the Demanding Holders may


                                        5



elect to withdraw from such offering by giving written notice to the Company and
the Underwriter or Underwriters of their request to withdraw prior to the
effectiveness of the Registration Statement filed with the Commission with
respect to such Demand Registration. If the majority in interest of the
Demanding Holders withdraws from a proposed underwritten offering relating to a
Demand Registration, then such registration shall not count as a Demand
Registration provided for in Section 2.1.1.

      2.2   Piggy-Back Registration.

            2.2.1.  Piggy-Back Rights. If at any time on or after the First
Release Date the Company proposes to file a Registration Statement under the
Securities Act with respect to an offering of equity securities, or securities
or other obligations exercisable or exchangeable for, or convertible into,
equity securities, by the Company for its own account or for the account of
other securityholders of the Company (or by the Company and by securityholders
of the Company including, without limitation, pursuant to Section 2.1), other
than a Registration Statement (i) filed in connection with any employee stock
option or other benefit plan, (ii) for an exchange offer or offering of
securities solely to the Company's existing shareholders, (iii) for an offering
of debt that is convertible into equity securities of the Company or (iv) for a
dividend reinvestment plan, then the Company shall (x) give written notice of
such proposed filing to the holders of Registrable Securities as soon as
practicable but in no event less than ten (10) days before the anticipated
filing date, which notice shall describe the amount and type of securities to be
included in such offering, the intended method(s) of distribution, and the name
of the proposed managing Underwriter or Underwriters, if any, of the offering,
and (y) offer to the holders of Registrable Securities in such notice the
opportunity to register the sale of such number of shares of Registrable
Securities as such holders may request in writing within fifteen (15) days
following receipt of such notice (a "Piggy-Back Registration"). The Company
shall cause such Registrable Securities to be included in such registration and
shall use its best efforts to cause the managing Underwriter or Underwriters of
a proposed underwritten offering to permit the Registrable Securities requested
to be included in a Piggy-Back Registration to be included on the same terms and
conditions as any similar securities of the Company and to permit the sale or
other disposition of such Registrable Securities in accordance with the intended
method(s) of distribution thereof. All holders of Registrable Securities
proposing to distribute their securities through a Piggy-Back Registration that
involves an Underwriter or Underwriters shall enter into an underwriting
agreement in customary form with the Underwriter or Underwriters selected for
such Piggy-Back Registration. The Company shall have no obligation under this
Section 2.2 to complete any offering of its securities that it proposes to make.

            2.2.2.  Reduction of Offering. If the managing Underwriter or
Underwriters for a Piggy-Back Registration that is to be an underwritten
offering advises the Company and the holders of Registrable Securities in
writing that the dollar amount or number of shares of Common Stock or other
securities which the Company desires to sell, taken together with shares of
Common Stock or other securities, if any, as to which registration has been
demanded pursuant to written contractual arrangements with persons other than
the holders of Registrable Securities hereunder, the Registrable Securities as
to which registration has been requested under this Section 2.2, and the shares
of Common Stock or other securities, if any, as to which registration has been
requested pursuant to the written contractual piggy-back registration rights


                                        6



of other shareholders of the Company, exceeds the Maximum Number of Shares, then
the Company shall include in any such registration:

                    (i)   first, the shares of Common Stock or other securities
that the Company desires to sell together with the Registrable Securities as to
which registration has been requested Pro Rata, that can be sold without
exceeding the Maximum Number of Shares; and;

                    (ii)  second, to the extent that the Maximum Number of
Shares has not been reached under the foregoing clause (i), the shares of Common
Stock or other securities for the account of other persons that the Company is
obligated to register pursuant to written contractual arrangements with such
persons, including, without limitation, any Purchase Option Securities, that can
be sold without exceeding the Maximum Number of Shares.

            2.2.3.  Withdrawal. Any holder of Registrable Securities may elect
to withdraw such holder's request for inclusion of Registrable Securities in any
Piggy-Back Registration by giving written notice to the Company of such request
to withdraw prior to the effectiveness of the Registration Statement. The
Company may also elect to withdraw a registration statement at any time prior to
the effectiveness of the Registration Statement. Notwithstanding any withdrawal
by the Company, the Company shall pay all expenses incurred by the holders of
Registrable Securities in connection with such Piggy-Back Registration as
provided in Section 3.3.

      2.3   Registrations on Form S-3. In case the Company shall, at any time
after the First Release Date be permitted to effect a registration on Form S-3
or other similar short-form registration which may be available at such time
with respect to all or a part of the Registrable Securities, the holders of
Registrable Securities shall be entitled to request in writing that the Company
register the resale of any or all of such Registrable Securities on Form S-3 or
such other similar short-form registration; provided, however, that the Company
shall not be obligated to effect such request through an underwritten offering.
Upon receipt of such written request, the Company will promptly give written
notice of the proposed registration to all other holders of Registrable
Securities, and, as soon as practicable thereafter, effect the registration of
all or such portion of such holder's or holders' Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any other holder or holders joining in such request as are
specified in a written request given within fifteen (15) days after receipt of
such written notice from the Company; provided, however, that the Company shall
not be obligated to effect any such registration pursuant to this Section 2.3 if
the holders of the Registrable Securities, together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities and such other securities (if any) at
any aggregate price to the public of less than $500,000. Registrations effected
pursuant to this Section 2.3 shall not be counted as Demand Registrations
effected pursuant to Section 2.1. Notwithstanding anything to the contrary
contained herein, the Company shall not be required to seek to cause a
Registration Statement with respect to a Form S-3 or other short-form
registration to become effective pursuant to this Section 2.3: (A) within a
period of ninety (90) days after the effective date of a Registration Statement
filed by the Company; provided, that the Company shall use commercially
reasonable efforts to cause a Form S-3 or other short-form registration
requested hereunder to be declared effective promptly following such period if
such a request is made during such period; or (B) if the Company shall furnish
to the requesting


                                        7



holder or holders, a certificate signed by the Chief Executive Officer of the
Company stating that in the good faith judgment of the Board of Directors of the
Company, the filing of a Registration Statement would, at such time, materially
and adversely affect (i) the financial condition of the Company, in view of a
requirement to disclose material non-public information relating to the Company,
which the Company has a bona fide business purpose for preserving as
confidential or (ii) an existing continuing negotiation relating to an
acquisition, disposition, corporate reorganization, private securities offering,
financing or similar transaction with respect to the Company, then the Company
shall have the right to defer such filing for a period of no more than ninety
(90) days; provided, however that the Company may not exercise this right more
than once during any period of twelve (12) consecutive months.

Statement, at any time that such holder elects to use a prospectus, an opinion
of counsel to the Company to the effect that the Registration Statement
containing such prospectus has been declared effective and that no stop order is
in effect.

            3.1.10. Earnings Statement. The Company shall comply with all
applicable rules and regulations of the Commission and the Securities Act, and
make available to its


                                       10



shareholders, as soon as practicable, an earnings statement covering a period of
twelve (12) months, beginning within three (3) months after the effective date
of the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

            3.1.11. Listing. The Company shall use its best efforts to cause all
Registrable Securities included in any registration to be listed on such
exchanges or otherwise designated for trading in the same manner as similar
securities issued by the Company are then listed or designated.

      3.2   Obligation to Suspend Distribution. Upon receipt of any notice from
the Company of the happening of any event of the kind described in Section
3.1.4(iv), or, in the case of a resale registration on Form S-3 or similar
short-form registration effected pursuant to Section 2.3 hereof, upon any
suspension by the Company, pursuant to a written insider trading compliance
program adopted by the Company's Board of Directors, of the ability of all
"insiders" covered by such program to transact in the Company's securities
because of the existence of material non-public information, each holder of
Registrable Securities included in any registration shall immediately
discontinue disposition of such Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities until such holder
receives the supplemented or amended prospectus contemplated by Section
3.1.4(iv) or the restriction on the ability of "insiders" to transact in the
Company's securities is removed, as applicable, and, if so directed by the
Company, each such holder will deliver to the Company all copies, other than
permanent file copies then in such holder's possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such
notice.

      3.3   Registration Expenses. The Company shall bear all costs and expenses
incurred in connection with any Demand Registration pursuant to Section 2.1, any
Piggy-Back Registration pursuant to Section 2.2, and any registration on Form
S-3 effected pursuant to Section 2.3, and all expenses incurred in performing or
complying with its other obligations under this Agreement, whether or not the
Registration Statement becomes effective, including, without limitation: (i) all
registration and filing fees; (ii) fees and expenses of compliance with
securities or "blue sky" laws (including fees and disbursements of counsel in
connection with blue sky qualifications of the Registrable Securities); (iii)
printing expenses; (iv) the Company's internal expenses (including, without
limitation, all salaries and expenses of its officers and employees); (v) the
fees and expenses incurred in connection with the listing of the Registrable
Securities as required by Section 3.1.11; (vi) National Association of
Securities Dealers, Inc. fees; (vii) fees and disbursements of counsel for the
Company and fees and expenses for independent certified public accountants
retained by the Company (including the expenses or costs associated with the
delivery of any opinions or comfort letters requested pursuant to Section
3.1.9); (viii) the fees and expenses of any special experts retained by the
Company in connection with such registration and (ix) the fees and expenses of
one legal counsel selected by the holders of a majority in interest of the
Registrable Securities included in such registration. The Company shall have no
obligation to pay any underwriting discounts or selling commissions attributable
to the Registrable Securities being sold by the holders thereof, which
underwriting discounts or selling commissions shall be borne by such holders.
Additionally, in an underwritten offering, all selling shareholders and the
Company shall bear the expenses of the


                                       11



underwriter pro rata in proportion to the respective amount of shares each is
selling in such offering.

      3.4   Information. The holders of Registrable Securities shall provide
such information as may reasonably be requested by the Company, or the managing
Underwriter, if any, in connection with the preparation of any Registration
Statement, including amendments and supplements thereto, in order to effect the
registration of any Registrable Securities under the Securities Act pursuant to
Section 2 and in connection with the Company's obligation to comply with federal
and applicable state securities laws.

      4.    INDEMNIFICATION AND CONTRIBUTION.

      4.1   Indemnification by the Company. The Company agrees to indemnify and
hold harmless each Investor and each other holder of Registrable Securities, and
each of their respective officers, employees, affiliates, directors, partners,
members, attorneys and agents, and each person, if any, who controls an Investor
and each other holder of Registrable Securities (within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act) (each, an "Investor
Indemnified Party"), from and against any expenses, losses, judgments, claims,
damages or liabilities, whether joint or several, arising out of or based upon
any untrue statement (or allegedly untrue statement) of a material fact
contained in any Registration Statement under which the sale of such Registrable
Securities was registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained in the Registration Statement,
or any amendment or supplement to such Registration Statement, or arising out of
or based upon any omission (or alleged omission) to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of the Securities Act or any rule or
regulation promulgated thereunder applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration; and the Company shall promptly reimburse the Investor Indemnified
Party for any legal and any other expenses reasonably incurred by such Investor
Indemnified Party in connection with investigating and defending any such
expense, loss, judgment, claim, damage, liability or action; provided, however,
that the Company will not be liable in any such case to the extent that any such
expense, loss, claim, damage or liability arises out of or is based upon any
untrue statement or allegedly untrue statement or omission or alleged omission
made in such Registration Statement, preliminary prospectus, final prospectus,
or summary prospectus, or any such amendment or supplement, in reliance upon and
in conformity with information furnished to the Company, in writing, by such
selling holder expressly for use therein. The Company also shall indemnify any
Underwriter of the Registrable Securities, their officers, employees,
affiliates, directors, partners, members and agents and each person who controls
such Underwriter on substantially the same basis as that of the indemnification
provided above in this Section 4.1.

      4.2   Indemnification by Holders of Registrable Securities. Each selling
holder of Registrable Securities will, in the event that any registration is
being effected under the Securities Act pursuant to this Agreement of any
Registrable Securities held by such selling holder, indemnify and hold harmless
the Company, each of its directors and officers and each Underwriter (if any),
and each other person, if any, who controls such selling holder or such
Underwriter or the Company within the meaning of the Securities Act or the
Exchange Act,


                                       12



against any losses, claims, judgments, damages or liabilities, whether joint or
several, insofar as such losses, claims, judgments, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or allegedly untrue statement of a material fact contained in any Registration
Statement under which the sale of such Registrable Securities was registered
under the Securities Act, any preliminary prospectus, final prospectus or
summary prospectus contained in the Registration Statement, or any amendment or
supplement to the Registration Statement, or arise out of or are based upon any
omission or the alleged omission to state a material fact required to be stated
therein or necessary to make the statement therein not misleading, if the
statement or omission was made in reliance upon and in conformity with
information furnished in writing to the Company by such selling holder expressly
for use therein, and shall reimburse the Company, its directors and officers,
and each such controlling person for any legal or other expenses reasonably
incurred by any of them in connection with investigation or defending any such
loss, claim, damage, liability or action. Each selling holder's indemnification
obligations hereunder shall be several and not joint and shall be limited to the
amount of any net proceeds actually received by such selling holder from the
sale of Registrable Securities which gave rise to such indemnification
obligation.

      4.3   Conduct of Indemnification Proceedings. Promptly after receipt by
any person of any notice of any loss, claim, damage or liability or any action
in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such
person (the "Indemnified Party") shall, if a claim in respect thereof is to be
made against any other person for indemnification hereunder, notify such other
person (the "Indemnifying Party") in writing of the loss, claim, judgment,
damage, liability or action; provided, however, that the failure by the
Indemnified Party to notify the Indemnifying Party shall not relieve the
Indemnifying Party from any liability which the Indemnifying Party may have to
such Indemnified Party hereunder, except and solely to the extent the
Indemnifying Party is actually prejudiced by such failure. If the Indemnified
Party is seeking indemnification with respect to any claim or action brought
against the Indemnified Party, then the Indemnifying Party shall be entitled to
participate in such claim or action, and, to the extent that it wishes, jointly
with all other Indemnifying Parties, to assume control of the defense thereof
with counsel satisfactory to the Indemnified Party. After notice from the
Indemnifying Party to the Indemnified Party of its election to assume control of
the defense of such claim or action, the Indemnifying Party shall not be liable
to the Indemnified Party for any legal or other expenses subsequently incurred
by the Indemnified Party in connection with the defense thereof other than
reasonable costs of investigation; provided, however, that in any action in
which both the Indemnified Party and the Indemnifying Party are named as
defendants, the Indemnified Party shall have the right to employ separate
counsel (but no more than one such separate counsel) to represent the
Indemnified Party and its controlling persons who may be subject to liability
arising out of any claim in respect of which indemnity may be sought by the
Indemnified Party against the Indemnifying Party, with the fees and expenses of
such counsel to be paid by such Indemnifying Party if, based upon the written
opinion of counsel of such Indemnified Party, representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, consent to entry of judgment or effect any
settlement of any claim or pending or threatened proceeding in respect of which
the Indemnified Party is or could have been a party and indemnity could have
been sought hereunder by such Indemnified Party, unless such judgment or
settlement includes an unconditional release of such Indemnified Party from all
liability arising out of such claim or proceeding.


                                       13



      4.4   Contribution.

            4.4.1.  If the indemnification provided for in the foregoing
Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of
any loss, claim, damage, liability or action referred to herein, then each such
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 loss, claim, damage, liability or action in such proportion as is
appropriate to reflect the relative fault of the Indemnified Parties and the
Indemnifying Parties in connection with the actions or omissions which resulted
in such loss, claim, damage, liability or action, as well as any other relevant
equitable considerations. The relative fault of any Indemnified Party and any
Indemnifying Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by such Indemnified Party or such Indemnifying Party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

            4.4.2.  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 4.4 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding Section
4.4.1. The amount paid or payable by an Indemnified Party as a result of any
loss, claim, damage, liability or action referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such Indemnified Party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 4.4, no holder of Registrable
Securities shall be required to contribute any amount in excess of the dollar
amount of the net proceeds (after payment of any underwriting fees, discounts,
commissions or taxes) actually received by such holder from the sale of
Registrable Securities which gave rise to such contribution obligation. 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.

      5.    UNDERWRITING AND DISTRIBUTION.

      5.1   Rule 144. The Company covenants that it shall file any reports
required to be filed by it under the Securities Act and the Exchange Act and
shall take such further action as the holders of Registrable Securities may
reasonably request, all to the extent required from time to time to enable such
holders to sell Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by Rule 144 under the
Securities Act, as such Rules may be amended from time to time, or any similar
Rule or regulation hereafter adopted by the Commission.

      6.    MISCELLANEOUS.

      6.1   Assignment; No Third Party Beneficiaries. This Agreement and the
rights, duties and obligations of the Company hereunder may not be assigned or

                                       14



Registrable Securities in conjunction with and to the extent of any transfer of
Registrable Securities by any such holder. This Agreement and the provisions
hereof shall be binding upon and shall inure to the benefit of each of the
parties and their respective successors and the permitted assigns of the
Investor or holder of Registrable Securities or of any assignee of the Investor
or holder of Registrable Securities. This Agreement is not intended to confer
any rights or benefits on any persons that are not party hereto other than as

and shall be personally served, delivered by reputable air courier service with
charges prepaid, or transmitted by hand delivery, telegram, telex or facsimile,
addressed as set forth below, or to such other address as such party shall have

given on the next business day. Notice otherwise sent as provided herein shall
be deemed given on the next business day following timely delivery of such
notice to a reputable air courier service with an order for next-day delivery.

      6.3   Severability. This Agreement shall be deemed severable, and the
invalidity or unenforceability of any term or provision hereof shall not affect
the validity or enforceability of this Agreement or of any other term or
provision hereof. Furthermore, in lieu of any such invalid or unenforceable term
or provision, the parties hereto intend that there shall be added as a part of
this Agreement a provision as similar in terms to such invalid or unenforceable
provision as may be possible and be valid and enforceable.

      6.4   Counterparts. This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original, and all of which taken
together shall constitute one and the same instrument.

      6.5   Entire Agreement. This Agreement (including all agreements entered
into pursuant hereto and all certificates and instruments delivered pursuant
hereto and thereto) constitute the entire agreement of the parties with respect
to the subject matter hereof and supersede all prior and contemporaneous
agreements, representations, understandings, negotiations and discussions

      6.6   Modifications and Amendments. This Agreement shall not be charged,
modified or amended except by a writing signed by the Company and the holdings
of at least a majority in interest of the then outstanding Registrable
Securities affected thereby.

      6.7   Titles and Headings. Titles and headings of sections of this
Agreement are for convenience only and shall not affect the construction of any
provision of this Agreement.

      6.8   Waivers and Extensions. Any party to this Agreement may waive any
right, breach or default which such party has the right to waive, provided that
such waiver will not be effective against the waiving party unless it is in
writing, is signed by such party, and specifically refers to this Agreement.
Waivers may be made in advance or after the right waived has arisen or the
breach or default waived has occurred. Any waiver may be conditional. No waiver
of any breach of any agreement or provision herein contained shall be deemed a
waiver of any preceding or succeeding breach thereof nor of any other agreement
or provision herein contained. No waiver or extension of time for performance of
any obligations or acts shall be deemed a waiver or extension of the time for
performance of any other obligations or acts.

      6.9   Remedies Cumulative. In the event that the Company fails to observe
or perform any covenant or agreement to be observed or performed under this
Agreement, the Investor or any other holder of Registrable Securities may
proceed to protect and enforce its rights by suit in equity or action at law,
whether for specific performance of any term contained in this Agreement or for
an injunction against the breach of any such term or in aid of the exercise of
any power granted in this Agreement or to enforce any other legal or equitable
right, or to take any one or more of such actions, without being required to
post a bond. None of the rights, powers or remedies conferred under this
Agreement shall be mutually exclusive, and each such right, power or remedy
shall be cumulative and in addition to any other right, power or remedy, whether
conferred by this Agreement or now or hereafter available at law, in equity, by
statute or otherwise.


                                       16



      6.10  Governing Law. This Agreement shall be governed by, interpreted
under, and construed in accordance with the internal laws of the State of New
York applicable to agreements made and to be performed within the State of New
York, without giving effect to any choice-of-law provisions thereof that would
compel the application of the substantive laws of any other jurisdiction. Each
of the parties hereby agrees that any action, proceeding or claim against it
arising out of or relating in any way to this Agreement shall be brought and
enforced in the courts of the State of New York or the United States District
Court for the Southern District of New York (each, a "New York Court"), and
irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive.
Each of the parties hereby waives any objection to such exclusive jurisdiction
and that such courts represent an inconvenient forum. [Each of ________________
and _________________ (together, the "non-U.S. Investors") has
appointed______________ as its authorized agent (the "Authorized Agent") upon
whom process may be served in any such action arising out of or based on this
Agreement or the transactions contemplated hereby which may be instituted in any
New York Court. Such appointment shall be irrevocable. The Company and the
Non-U.S. Investors represent and warrant that the Authorized Agent has agreed to
act as such agent for services of process and agrees to take any and all action,
including the filing of any and all documents and instruments that may be
necessary to continue such appointment in full force and effect as aforesaid.
Service of process upon the Authorized Agent and written notice of such service
to the Company shall be deemed, in every respect, effective service of process
upon the respective Non-U.S. Investors.]

      6.11  Waiver of Trial by Jury. Each party hereby irrevocably and
unconditionally waives the right to a trial by jury in any action, suit,
counterclaim or other proceeding (whether based on contract, tort or otherwise)
arising out of, connected with or relating to this Agreement, the transactions
contemplated hereby, or the actions of the Investor in the negotiation,
administration, performance or enforcement hereof.
