of the Registrable Securities on such Filing Date for an offering to be made on
a continuous basis pursuant to Rule 415. The Registration Statement shall be on

attached hereto as Annex A. Subject to the terms of this Agreement, the Company
shall 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 applicable Effectiveness Date, and shall
use its best efforts to keep such Registration Statement continuously effective
under the Securities Act until all Registrable Securities covered by such
Registration Statement have been sold or may be sold without volume restrictions
pursuant to Rule 144(k) as determined by the counsel to the Company pursuant to
a written opinion letter to such effect, addressed and acceptable to the
Company's transfer agent and the affected Holders (the "Effectiveness Period").
The Company shall immediately notify the Holders via facsimile of the
effectiveness of the Registration Statement on the same day that the Company
receives notification of the effectiveness from the Commission. Failure to so
notify the Holder within 1 Trading Day of such notification shall be deemed an
Event under Section 2(b).

Date (if the Company files a Registration Statement without affording the
Holders the opportunity to review and comment on the same as required by Section
3(a), the Company shall not be deemed to have satisfied this clause (i)), or
(ii) the Company fails to file with the Commission a request for acceleration in
accordance with Rule 461 promulgated under the Securities Act, within five

whichever is earlier) by the Commission that a Registration Statement will not
be "reviewed," or not subject to further review, or (iii) prior to its
Effectiveness Date, the Company fails to file a pre-effective amendment and
otherwise respond in writing to comments made by the Commission in respect of
such Registration Statement within 10 calendar days after the receipt of
comments by or notice from the Commission that such amendment is required in
order for a Registration Statement to be declared effective, or (iv) a
Registration Statement filed or required to be filed hereunder is not declared
effective by the Commission by its Effectiveness Date, or (v) after the
Effectiveness Date, a Registration Statement ceases for any reason to remain
continuously effective as to all Registrable Securities for which it is required
to be effective, or the Holders are not permitted to utilize the Prospectus
therein to resell such Registrable Securities for 10 consecutive calendar days
but no more than an aggregate of 15 calendar days during any 12-month period
(which need not be consecutive Trading Days) (any such failure or breach being


                                        3

<PAGE>

referred to as an "Event", and for purposes of clause (i) or (iv) the date on
which such Event occurs, or for purposes of clause (ii) the date on which such
five Trading Day period is exceeded, or for purposes of clause (iii) the date
which such 10 calendar day period is exceeded, or for purposes of clause (v) the
date on which such 10 or 15 calendar day period, as applicable, is exceeded
being referred to as "Event Date"), then in addition to any other rights the
Holders may have hereunder or under applicable law, on each such Event Date and
on each monthly anniversary of each such Event Date (if the applicable Event
shall not have been cured by such date) until the applicable Event is cured, the
Company shall pay to each Holder an amount in cash, as partial liquidated
damages and not as a penalty, equal to 1% of the aggregate purchase price paid
by such Holder pursuant to the Purchase Agreement for any Registrable Securities
then held by such Holder for the first 30 days during the occurrence of an Event
and 1.5% for each month thereafter. If the Company fails to pay any partial
liquidated damages pursuant to this Section in full within seven days after the
date payable, the Company will pay interest thereon at a rate of 18% per annum
(or such lesser maximum amount that is permitted to be paid by applicable law)
to the Holder, accruing daily from the date such partial liquidated damages are
due until such amounts, plus all such interest thereon, are paid in full. The
partial liquidated damages pursuant to the terms hereof shall apply on a daily
pro-rata basis for any portion of a month prior to the cure of an Event.

     3. Registration Procedures

     In connection with the Company's registration obligations hereunder, the
Company shall:

     (a) Not less than five Trading Days prior to the filing of each
Registration Statement or any related Prospectus or any amendment or supplement
thereto (including any document that would be incorporated or deemed to be

Holder copies of all such documents proposed to be filed, which documents (other
than those incorporated or deemed to be incorporated by reference) will be
subject to the review of such Holders, 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 respective
counsel to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file the Registration Statement or any
such Prospectus or any amendments or supplements thereto to which the Holders of
a majority of the Registrable Securities shall reasonably object in good faith,
provided that, the Company is notified of such objection in writing no later
than 5 Trading Days after the Holders have been so furnished copies of such
documents. Each Holder agrees to furnish to the Company a completed
Questionnaire in the form attached to this Agreement as Annex B (a "Selling
Shareholder Questionnaire") not less than two Trading Days prior to the Filing
Date or by the end of the fourth Trading Day following the date on which such
Holder receives draft materials in accordance with this Section.

     (b) (i) Prepare and file with the Commission such amendments, including
post-effective amendments, to a Registration Statement and the Prospectus used
in connection therewith as may be necessary to keep a Registration Statement
continuously effective as to the applicable Registrable Securities for the
Effectiveness Period and prepare and file with the Commission such additional
Registration Statements in order to register for resale under the


                                        4

<PAGE>

Securities Act all of the Registrable Securities; (ii) cause the related
Prospectus to be amended or supplemented by any required Prospectus supplement
(subject to the terms of this Agreement), and as so supplemented or amended to
be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible
to any comments received from the Commission with respect to a Registration
Statement or any amendment thereto and as promptly as reasonably possible
provide the Holders true and complete copies of all correspondence from and to
the Commission relating to a Registration Statement; and (iv) comply in all
material respects with the provisions of the Securities Act and the Exchange Act
with respect to the disposition of all Registrable Securities covered by a
Registration Statement during the applicable period in accordance (subject to
the terms of this Agreement) with the intended methods of disposition by the
Holders thereof set forth in such Registration Statement as so amended or in
such Prospectus as so supplemented.

     (c) If during the Effectiveness Period, the number of Registrable
Securities at any time exceeds 90% of the number of shares of Common Stock then
registered in a Registration Statement, then the Company shall file as soon as
reasonably practicable but in any case prior to the applicable Filing Date, an
additional Registration Statement covering the resale by the Holders of not less
than [125% of the number of such Registrable Securities.

     (d) Notify the Holders of Registrable Securities to be sold (which notice
shall, pursuant to clauses (ii) through (vi) hereof, be accompanied by an
instruction to suspend the use of the Prospectus until the requisite changes
have been made) as promptly as reasonably possible (and, in the case of (i)(A)
below, not less than five Trading Days prior to such filing) and (if requested
by any such Person) confirm such notice in writing no later than one Trading Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to a 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 (the Company shall provide true and complete copies
thereof and all written responses thereto to each of the Holders); and (C) with
respect to a 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 a
Registration Statement or Prospectus or for additional information; (iii) of the
issuance by the Commission or any other federal or state governmental authority
of any stop order suspending the effectiveness of a Registration Statement
covering any or all of the Registrable Securities or the initiation of any
Proceedings for that purpose; (iv) 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; (v) of the occurrence of any event or passage of time that makes the
financial statements included in a Registration Statement ineligible for
inclusion therein or any statement made in a 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 a
Registration Statement, Prospectus or other documents so that, in the case of a
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


                                        5

<PAGE>

misleading; and (vi) the occurrence or existence of any pending corporate
development with respect to the Company that the Company believes may be
material and that, in the determination of the Company, makes it not in the best
interest of the Company to allow continued availability of the Registration
Statement or Prospectus; provided that any and all of such information shall
remain confidential to each Holder until such information otherwise becomes
public, unless disclosure by a Holder is required by law; provided, further,
notwithstanding each Holder's agreement to keep such information confidential,
the Holders make no acknowledgement that any such information is material,
non-public information.

     (e) Use its best efforts to avoid the issuance of, or, if issued, obtain
the withdrawal of (i) any order suspending the effectiveness of a 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.

     (f) Furnish to each Holder, without charge, at least one conformed copy of
each such Registration Statement and each amendment thereto, including financial
statements and schedules, all documents incorporated or deemed to be
incorporated therein by reference to the extent requested by such Person, and
all exhibits to the extent requested by such Person (including those previously
furnished or incorporated by reference) promptly after the filing of such
documents with the Commission.

     (g) Promptly deliver to each Holder, without charge, as many copies of the
Prospectus or Prospectuses (including each form of prospectus) and each
amendment or supplement thereto as such Persons may reasonably request in
connection with resales by the Holder of Registrable Securities. Subject to the
terms of this Agreement, the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto, except after
the giving on any notice pursuant to Section 3(d).

     (h) If NASDR Rule 2710 requires any broker-dealer to make a filing prior to
executing a sale by a Holder, make an Issuer Filing with the NASDR, Inc.
Corporate Financing Department pursuant to NASDR Rule 2710(b)(10)(A)(i) and
respond within five Trading Days to any comments received from NASDR in
connection therewith, and pay the filing fee required in connection therewith.

     (i) Prior to any resale of Registrable Securities by a Holder, use its
commercially reasonable efforts to register or qualify or cooperate with the
selling Holders in connection with the registration or qualification (or
exemption from the Registration or qualification) of such Registrable Securities
for the resale by the Holder under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder reasonably requests in
writing, to keep each registration or qualification (or exemption therefrom)
effective during the Effectiveness Period and to do any and all other acts or
things reasonably necessary to enable the disposition in such jurisdictions of
the Registrable Securities covered by each Registration Statement; provided,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it


                                        6

<PAGE>

is not then so qualified, subject the Company to any material tax in any such
jurisdiction where it is not then so subject or file a general consent to
service of process in any such jurisdiction.

     (j) If requested by the Holders, cooperate with the Holders to facilitate
the timely preparation and delivery of certificates representing Registrable
Securities to be delivered to a transferee pursuant to a Registration Statement,
which certificates shall be free, to the extent permitted by the Purchase
Agreement, of all restrictive legends, and to enable such Registrable Securities
to be in such denominations and registered in such names as any such Holders may
request.

     (k) Upon the occurrence of any event contemplated by this Section 3, as
promptly as reasonably possible under the circumstances taking into account the
Company's good faith assessment of any adverse consequences to the Company and
its stockholders of the premature disclosure of such event, prepare a supplement
or amendment, including a post-effective amendment, to a Registration Statement
or a supplement to the related Prospectus or any document incorporated or deemed
to be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither a Registration Statement nor such
Prospectus will contain an untrue statement of a material fact or omit to state
a 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. If the Company notifies the Holders in accordance with clauses
(ii) through (vi) of Section 3(d) above to suspend the use of any Prospectus
until the requisite changes to such Prospectus have been made, then the Holders
shall suspend use of such Prospectus. The Company will use its best efforts to
ensure that the use of the Prospectus may be resumed as promptly as is
practicable. The Company shall be entitled to exercise its right under this
Section 3(j) to suspend the availability of a Registration Statement and
Prospectus, subject to the payment of partial liquidated damages pursuant to
Section 2(b), for a period not to exceed 60 days (which need not be consecutive
days) in any 12 month period.

     (l) Comply with all applicable rules and regulations of the Commission.

     (m) The Company may require each selling Holder to furnish to the Company a
certified statement as to the number of shares of Common Stock beneficially
owned by such Holder and, if required by the Commission, the person thereof that
has voting and dispositive control over the Shares. During any periods that the
Company is unable to meet its obligations hereunder with respect to the
registration of the Registrable Securities solely because any Holder fails to
furnish such information within three Trading Days of the Company's request, any
liquidated damages that are accruing at such time as to such Holder only shall
be tolled and any Event that may otherwise occur solely because of such delay
shall be suspended as to such Holder only, until such information is delivered
to the Company.

     4. Registration Expenses. All fees and expenses incident to the performance
of or compliance with this Agreement by the Company shall be borne by the
Company 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

NASD Rule 2710, so long as the broker is receiving no more than a customary
brokerage commission in connection with such sale, (ii) printing expenses

prospectuses is reasonably requested by the holders of a majority of the
Registrable Securities included in a Registration Statement), (iii) messenger,

Holders.

of each of them, each Person who controls any such Holder (within the meaning of

reasonable 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 a 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 (i) such
untrue statements or omissions are based solely upon information regarding such
Holder furnished in writing to the Company by 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


                                        8

<PAGE>

expressly approved in writing by such Holder expressly for use in a Registration
Statement, such Prospectus or such form of Prospectus or in any amendment or
supplement thereto (it being understood that the Holder has approved Annex A
hereto for this purpose) or (ii) in the case of an occurrence of an event of the
type specified in Section 3(d)(ii)-(vi), the use by such Holder of an outdated
or defective Prospectus after the Company has notified such Holder in writing
that the Prospectus is outdated or defective and prior to the receipt by such
Holder of the Advice contemplated in Section 6(d). The Company shall notify the
Holders promptly of the institution, threat or assertion of any Proceeding
arising from or in connection with the transactions contemplated by this
Agreement of which the Company is aware.

     (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its 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
incurred, to the extent arising out of or based solely upon: (x) such Holder's
failure to comply with the prospectus delivery requirements of the Securities
Act or (y) any untrue or alleged untrue statement of a material fact contained
in any 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 not
misleading (i) 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 such Registration Statement
or such Prospectus or (ii) to the extent that (1) such untrue statements or
omissions are based solely upon information regarding such Holder furnished in
writing to the Company by 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 (it being understood that the Holder has approved Annex A hereto for
this purpose), such Prospectus or such form of Prospectus or in any amendment or
supplement thereto or (2) in the case of an occurrence of an event of the type
specified in Section 3(d)(ii)-(vi), the use by such Holder of an outdated or
defective Prospectus after the Company has notified such Holder in writing that
the Prospectus is outdated or defective and prior to the receipt by such Holder
of the Advice contemplated in Section 6(d). 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 shall promptly notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall have the right to 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)


                                        9

<PAGE>

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 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; (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 reasonably believe that a material 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 the reasonable fees and expenses of one
separate 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.

     Subject to the terms of this Agreement, all reasonable 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 ten Trading Days of written notice thereof to the
Indemnifying Party; provided, that the Indemnified Party shall promptly
reimburse the Indemnifying Party for that portion of such fees and expenses
applicable to such actions for which such Indemnified Party is not entitled to
indemnification hereunder, determined based upon the relative faults of the
parties.

     (d) Contribution. If the indemnification under Section 5(a) or 5(b) is
unavailable to an Indemnified Party or insufficient to hold an Indemnified Party
harmless for any Losses, then each Indemnifying Party shall contribute to the
amount paid or payable by such Indemnified Party, 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 this Agreement, any


                                       10

<PAGE>

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, except in the case of fraud by
such Holder.

     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. 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 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. The Company shall not file any other registration
statements until the initial Registration Statement required hereunder is
declared effective by the Commission, provided that this Section 6(b) shall not
prohibit the Company from filing amendments to registration statements already
filed.

     (c) Compliance. Each Holder covenants and agrees that it will comply with
the prospectus delivery requirements of the Securities Act as applicable to it
in connection with sales of Registrable Securities pursuant to the Registration
Statement.

     (d) Discontinued Disposition. 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(d), such Holder will
forthwith discontinue disposition of such Registrable Securities under a
Registration Statement until such Holder's receipt of the copies of the
supplemented Prospectus and/or amended Registration Statement, or until it is


                                       11

<PAGE>

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. The
Company will use its best efforts to ensure that the use of the Prospectus may
be resumed as promptly as it practicable. The Company agrees and acknowledges
that any periods during which the Holder is required to discontinue the
disposition of the Registrable Securities hereunder shall be subject to the
provisions of Section 2(b).

     (e) Piggy-Back Registrations. If at any time during the Effectiveness
Period there is not an effective Registration Statement covering all of the
Registrable Securities and 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 the stock option or other employee
benefit plans, then the Company shall send to each Holder a written notice of
such determination and, if within fifteen days after the date of such notice,
any such Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
holder requests to be registered; provided, that, the Company shall not be
required to register any Registrable Securities pursuant to this Section 6(e)
that are eligible for resale pursuant to Rule 144(k) promulgated under the
Securities Act or that are the subject of a then effective Registration
Statement.

     (f) 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 each Holder of
the then outstanding Registrable Securities. 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 all 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.

     (g) Notices. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be delivered as set forth
in the Purchase Agreement.

     (h) 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 all of the
Holders of the then-outstanding Registrable Securities. Each Holder may assign
their respective rights hereunder in the manner and to the Persons as permitted
under the Purchase Agreement. Any Public Liquidity Company that is not the
Company shall, as a condition to any Public Liquidity Event, agree to, and be
bound by, all the terms, conditions and obligations set forth hereunder.


                                       12

<PAGE>

     (i) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has entered, 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 would have the effect of
impairing the rights granted to the Holders in this Agreement or otherwise
conflicts with the provisions hereof. Except as set forth on Schedule 6(i),
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 that have not been satisfied in full.

     (j) Execution and 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.

     (k) Governing Law. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be determined with the
provisions of the Purchase Agreement.

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

     (m) 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 commercially 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.

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

     (o) Independent Nature of Holders' Obligations and Rights. The obligations
of each Holder hereunder are several and not joint with the obligations of any
other Holder hereunder, and no Holder shall be responsible in any way for the
performance of the obligations of any other Holder hereunder. Nothing contained
herein or in any other agreement or document delivered at any closing, and no
action taken by any Holder pursuant hereto or thereto, shall be deemed to
constitute the Holders as a partnership, an association, a joint venture or any
other kind of entity, or create a presumption that the Holders are in any way
acting in concert with respect to such obligations or the transactions
contemplated by this Agreement. Each Holder shall be entitled to protect and
enforce its rights, including without limitation the rights arising


                                       13

<PAGE>

out of this Agreement, and it shall not be necessary for any other Holder to be
joined as an additional party in any proceeding for such purpose.

                              Plan of Distribution

     Each Selling Stockholder (the "Selling Stockholders") of the common stock
("Common Stock") of [_______, a [______ corporation (the "Company") and any of
their pledgees, assignees and successors-in-interest may, from time to time,
sell any or all of their shares of Common Stock on the Trading Market or any
other stock exchange, market or trading facility on which the shares are traded
or in private transactions. These sales may be at fixed or negotiated prices. A
Selling Stockholder may use any one or more of the following methods when
selling shares:

          -    ordinary brokerage transactions and transactions in which the
               broker-dealer solicits purchasers;

          -    block trades in which the broker-dealer will attempt to sell the
               shares as agent but may position and resell a portion of the
               block as principal to facilitate the transaction;

          -    purchases by a broker-dealer as principal and resale by the
               broker-dealer for its account;

          -    an exchange distribution in accordance with the rules of the
               applicable exchange;

          -    privately negotiated transactions;

          -    settlement of short sales entered into after the date of this
               prospectus;

          -    broker-dealers may agree with the Selling Stockholders to sell a
               specified number of such shares at a stipulated price per share;

          -    a combination of any such methods of sale;

          -    through the writing or settlement of options or other hedging
               transactions, whether through an options exchange or otherwise;
               or

          -    any other method permitted pursuant to applicable law.

     The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), if available, rather
than under this prospectus.

     Broker-dealers engaged by the Selling Stockholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated, but, except as set forth in a supplement to this Prospectus, in the
case of an agency transaction not in excess of a customary brokerage commission
in compliance with NADSR Rule 2440; and in the case of a principal transaction a
markup or markdown in compliance with NASDR IM-2440.


                                       17

<PAGE>

     In connection with the sale of the Common Stock or interests therein, the
Selling Stockholders may enter into hedging transactions with broker-dealers or
other financial institutions, which may in turn engage in short sales of the
Common Stock in the course of hedging the positions they assume. The Selling
Stockholders may also sell shares of the Common Stock short and deliver these
securities to close out their short positions, or loan or pledge the Common
Stock to broker-dealers that in turn may sell these securities. The Selling
Stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more
derivative securities which require the delivery to such broker-dealer or other
financial institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this
prospectus (as supplemented or amended to reflect such transaction).

     The Selling Stockholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act. Each Selling Stockholder has informed the
Company that it does not have any written or oral agreement or understanding,
directly or indirectly, with any person to distribute the Common Stock. In no
event shall any broker-dealer receive fees, commissions and markups which, in
the aggregate, would exceed eight percent (8%).

     The Company is required to pay certain fees and expenses incurred by the
Company incident to the registration of the shares. The Company has agreed to
indemnify the Selling Stockholders against certain losses, claims, damages and
liabilities, including liabilities under the Securities Act.

     Because Selling Stockholders may be deemed to be "underwriters" within the
meaning of the Securities Act, they will be subject to the prospectus delivery
requirements of the Securities Act. In addition, any securities covered by this
prospectus which qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than under this prospectus. Each Selling
Stockholder has advised us that they have not entered into any written or oral
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the resale shares. There is no underwriter or coordinating
broker acting in connection with the proposed sale of the resale shares by the
Selling Stockholders.

     We agreed to keep this prospectus effective until the earlier of (i) the
date on which the shares may be resold by the Selling Stockholders without
registration and without regard to any volume limitations by reason of Rule
144(e) under the Securities Act or any other rule of similar effect or (ii) all
of the shares have been sold pursuant to the prospectus or Rule 144 under the
Securities Act or any other rule of similar effect. The resale shares will be
sold only through registered or licensed brokers or dealers if required under
applicable state securities laws. In addition, in certain states, the resale
shares may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.


                                       18

<PAGE>

     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the resale shares may not simultaneously engage
in market making activities with respect to the Common Stock for a period of two
business days prior to the commencement of the distribution. In addition, the
Selling Stockholders will be subject to applicable provisions of the Exchange
Act and the rules and regulations thereunder, including Regulation M, which may
limit the timing of purchases and sales of shares of the Common Stock by the
Selling Stockholders or any other person. We will make copies of this prospectus
available to the Selling Stockholders and have informed them of the need to
deliver a copy of this prospectus to each purchaser at or prior to the time of
the sale.
