constitutes a legal, valid and binding obligation of the Purchaser enforceable
against the Purchaser in accordance with its terms, except as enforceability (a)

Securities are being acquired by the Purchaser for investment for the
Purchaser's own account, not as a nominee or agent, and not with a view to or
for sale in connection with any distribution of the Purchased Securities or any
part thereof, and that the Purchaser has no present intention of selling,
granting any participation in, or otherwise distributing the same, but subject
nevertheless to any requirement of law that the disposition of the Purchaser's
property shall at all times be within its control.  By executing this Agreement,
the Purchaser further represents that it does not have any contract,
undertaking, agreement or arrangement with any Person to sell, transfer, or
grant participations to such Person, or to any third Person, with respect to the

in evaluating and investing in companies in the development stage, is able to
fend for itself, has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of its investment in

during the course of the transaction and prior to its purchase of the Purchased
Securities hereunder, to all information as it deems necessary or appropriate
(to the extent the Company possessed such information or could acquire it
without unreasonable effort or expense) and that the Purchaser has had, during
the course of the transaction and prior to its purchase of the Purchased
Securities hereunder, the opportunity to ask questions of, and receive answers
from, the Company concerning the terms and conditions of the offering and to
obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify the accuracy of any information furnished to the Purchaser
or to which the Purchaser had access.  The foregoing, however, does not limit or
modify the representations and warranties of the Company and the Stockholder
contained in Article 3 of this Agreement or the right of the Purchaser to rely
thereon.

Securities, or any portion thereof, may not be sold, transferred, or otherwise

particular, the Purchaser is aware that the Purchased Securities may not be sold
pursuant to Rule 144 unless all of the conditions of that Rule are met. Among

COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

written consent of the Company, any public offering or sale of the Purchased

                   ARTICLE 8. REGISTRATION UNDER THE SECURITIES ACT

    8.01 NOTICE OF PROPOSED DISPOSITIONS. The Holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 8.01.  Prior to any proposed
disposition of any Restricted Securities (unless there is in effect a
registration statement under the Securities Act covering such proposed
disposition and such disposition is made in accordance with such registration
statement) the holder thereof shall give written notice to the Company of such
Holder's intention to effect such disposition.  Each such notice shall describe
the manner and circumstances of the proposed disposition, and shall be
accompanied (except in transactions intended to comply with Rule 144) by either
(a) a written opinion of legal counsel addressed to the Company and reasonably
satisfactory in form and substance to the Company, to the effect that the
proposed disposition of Restricted Securities may be effected without
Registration of such Restricted Securities or (b) a "no action" letter from the
Commission to the effect that such disposition without Registration of such
Restricted Securities will not result in a recommendation by the staff of the
Commission that enforcement action be taken with respect thereto, whereupon the
Holder of such Restricted Securities shall be entitled to transfer such
Restricted Securities in accordance with the terms of the notice delivered by
the Holder to the Company. Each certificate evidencing the Restricted Securities
disposed of as above provided shall bear the legend set forth in Section 4.06 of
this Agreement, except that such certificate shall not bear such legend if (1)
the opinion of counsel referred to above is to the further effect that





such legend is not required in order to establish compliance with any provisions
of the Securities Act, (2) the transfer is in connection with a transaction
intended to comply with Rule 144, or (3) an appropriate registration statement
with respect to such Restricted Securities has been filed by the Company with
the Commission and has been declared effective by the Commission; in those
events, the Company shall cause new legended certificates to be issued promptly
to the Holder in exchange for outstanding legended certificates.

    8.02 COMPANY REGISTRATION.

    (a)  If at any time, or from time to time, the Company shall determine to
Register any of its securities either for its own account or for the account of
any holder of its securities (including a Holder) (other than pursuant to
Section 8.03 or 8.05 hereof), other than a Registration relating solely to
employee benefit plans, or a Registration relating solely to a Rule 145
transaction or a Registration on any Registration form that does not permit
secondary sales, the Company will:

         (1)  promptly give to each Holder written notice thereof;

         (2)  include in such Registration (and any related qualification
         under Blue Sky Laws or other compliance), and in any underwriting
         involved therein, all the Registrable Securities specified in a
         written request or requests made within 20 days after receipt of
         such written notice from the Company, by any Holder or Holders,
         except as set forth in Section 8.02(b) hereof.  Any such written
         request may specify all or a part of a Holder's Registrable
         Securities.

    (b)  If the Registration of which the Company gives notice is for a
Registered public offering involving an underwriting, the Company shall so
advise the Holders as part of the written notice given pursuant to Section
8.02(a) hereof.  In such event, the right of a Holder to Registration pursuant
to this Section 8.02 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting to the extent provided herein.  All Holders proposing to
distribute their Registrable Securities through such underwriting shall
(together with the Company and the other holders of securities of the Company
with registration rights to participate therein distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting by the
Company.  Notwithstanding any other provision of this Section 8.02, if the
underwriter advises the Company in writing that marketing factors require a
limitation on the number





of shares to be underwritten, the underwriter may limit the amount of
Registrable Securities to be included in the Registration and underwriting, and
the number of shares to be included in such underwriting or Registration shall
be allocated as set forth in Section 13 hereof.

    8.03 DEMAND REGISTRATION.

    (a)  At any time following the earlier of (1) December 23, 1999, and (2)
one year after the effective date of the first registration statement filed by
the Company covering an underwritten offering of any of its securities to the
public, if the Company shall receive a written request (specifying that it is
being made pursuant to this Section 8.03) from any Holder or Holders that the
Company file a registration statement under the Securities Act covering the
Registration of at least 50% of the Registrable Securities, then the Company
shall promptly notify all other Holders of such request and shall use its best
efforts to cause all Registrable Securities that Holders have requested within
20 days after receipt of the Company's notice to be registered under the
Securities Act.  The Company shall be obligated to effect no more than two
Registrations pursuant to this Section 8.03 and the Company shall not be
obligated to effect any Registration pursuant to this Section 8.03 if the
written request therefor is made within 12 months following the effective date
of any previous registration statement filed by the Company pursuant to this
Section 8.03.

    (b)  Notwithstanding the foregoing, the Company shall not be obligated to
effect a Registration pursuant to Section 8.03(a) with respect to a proposed
distribution of Registrable Securities by a Holder thereof (1) during the period
starting with the date 30 days prior to the Company's estimated date of filing
of, and ending on a date 90 days following the effective date of, a registration
statement pertaining to an underwritten public offering of securities for the
account of the Company, provided that the Company is actively employing in good
faith all reasonable efforts to cause such registration statement to become
effective and that the Company's estimate of the date of filing of such
Registration is made in good faith; (2) within a period of 180 days after the
effective date of any previous Registration by the Company with respect to which
Holders of Registrable Securities were given the opportunity pursuant to this
Article 8 of this Agreement, to include therein all Registrable Securities which
were requested to be included therein; (3) if the Holders propose to dispose of
Registrable Securities which may be immediately registered on Form S-3 pursuant
to a request made under Section 8.05 hereof; or (4) if (i) in the good faith
judgment of the Board of Directors of the Company, such Registration would be
seriously detrimental to the Company and the Board of Directors of the Company
concludes, as a result, that it is essential to defer the filing of a
registration statement with respect to such Registration at such time, and (ii)





the Company shall furnish to the Holders requesting such Registration a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Director of the Company it would be seriously
detrimental to the Company for such registration statement to be filed in the
near future, and that it is, therefore essential to defer such filing (except as
provided in clause (1) above) for a period of not more than 180 days after the
receipt of the such request, and provided further, that the Company may not
defer its obligation in the manner provided in this clause (4) more than once in
any 12-month period.

    (c)  Any Registration statement filed pursuant to this Section 8.03 may,
subject to the provisions of Section 8.13 hereof, include other securities of
the Company with respect to which registration rights have been granted.

    8.04 EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with any Registration, qualification or compliance pursuant to
Sections 8.02, 8.03 and 8.04 hereof, shall be borne by the Company.  All Selling
Expenses relating to the Registrable Securities so Registered shall be borne by
the Holders of such Registrable Securities pro rata on the basis of the number
of shares of Registrable Securities so Registered on their behalf.

    8.05 REGISTRATION ON FORM S-3. After its initial public offering, the
Company shall use its best efforts to quality for registration on Form S-3 or
any comparable or successor form or forms.  After the Company has qualified for
the use of Form S-3, in addition to the rights contained in the foregoing
provisions of this Article 8, the Holders of Registrable Securities shall have
the right to request registrations on Form S-3 (such requests shall be in
writing and shall state the number of shares of Registrable Securities to be
disposed of and the intended methods of disposition of such shares by such
Holder or Holders), provided, however, that the Company shall not be obligated
to effect any such Registration if (1) the Company shall have delivered to such
Holder an opinion of counsel to the Company, addressed to such Holder and
reasonably satisfactory in form and substance to such Holder to the effect that
such Registrable Securities proposed to be included may lawfully be so disposed
of without Registration or (2) within a period of 180 days after the effective
date of any previous such Registration.  If a request complying with the
requirements of this Section 8.04 is delivered to the Company, the provisions of
Section 8.03(a) shall apply to such Registration.

    8.06 REGISTRATION PROCEDURES. In the case of each Registration effected by
the Company pursuant to this Article 8, the Company will keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof.  At its expense, the Company will:





    (a)  Keep such registration effective for a period of 180 days or until the
Holder or Holders have completed the distribution described in the registration
statement relating thereto, whichever first occurs; provided, however, that (i)
such 180-day period shall be extended for a period of time equal to the period
the Holder refrains from selling any securities included in such Registration at
the request of an underwriter of Common Stock (or other securities) of the
Company; and (ii) in the case of any registration of Registrable Securities on
Form S-3 which are intended to be. offered on a continuous or delayed basis,
such 180-day period shall be extended, if necessary, to keep the registration
statement effective until all such Registrable Securities are sold, provided
that Rule 145, or any successor rule under the Securities Act, permits an
offering on a continuous or delayed basis, and provided further that applicable
rules under the Securities Act governing the obligation to file a post-effective
amendment permit, in lieu of filing a post-effective amendment that (1) includes
any prospectus required by Section 10(a)(3) of the Securities Act or (2)
reflects facts or events representing a material or fundamental change in the
information set forth in the registration statement, the incorporation by
reference of information required to be included in (1) and (2) above to be
contained in periodic reports filed pursuant to Section 13 or 15(d) of the
Exchange Act in the registration statement;

    (b)  Prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement;

    (c)  Furnish such number of prospectuses and other documents incident
thereto, including any amendment of or supplement to the prospectus, as a Holder
from time to time may reasonably request;

    (d)  Register or qualify the securities covered by such registration
statement under the Blue Sky Laws of such jurisdictions as shall be reasonably
appropriate for the distribution of the securities covered thereby;

    (e)  At the time when any Registration statement pursuant to this Section 8
becomes effective, and at the time when any post-effective amendment thereto
becomes effective, furnish to the Holder or Holders of the Registrable
Securities being registered under such Registration statement, an opinion of
counsel satisfactory to such Holder or Holders to the effect that (1) to the
best knowledge of such counsel, no stop order suspending the effectiveness of
the Registration statement has been issued and no proceedings for that purpose
have been instituted or are pending or contemplated under the Securities Act,
(2) the Registration statement and the prospectus, and each amendment or
supplement





thereto, as of their respective effective or issue dates, comply as to form in
all material respects with the requirements of the Securities Act, (3) such
counsel has no reason to believe that the Registration statement, the
prospectus, or any amendment or supplement thereto, as of their respective
dates, contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and (4) the descriptions in the Registration statement,
the prospectus and any amendment or supplement thereto of statutes, legal and
governmental proceedings, and contracts or other documents are accurate and
fairly present the information required to be shown, and such counsel does not
know of any legal or governmental proceedings required to be described in the
Registration statement, the prospectus or any amendment or supplement thereto
which are not described as required, nor of any contracts or documents of a
character required to be described in the Registration statement or prospectus
or any amendment or supplement thereto, or to be filed as exhibits to the
Registration statement which are not described and filed as required, provided
that such counsel need not express any opinion as to the financial statements
and schedules included in or omitted from any such Registration statement,
prospectus or amendment or supplement thereto.

    (f)  Notify each seller of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing, and at the request of any such seller, prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such shares, such prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make such statements therein not misleading or
incomplete in the light of the circumstances then existing;

    (g)  Cause all such Registrable Securities registered pursuant hereunder to
be listed on each securities exchange on which similar securities issued by the
Company are then listed;

    (h)  Provide a transfer agent and registrar for all Registrable Securities

    (i)  Otherwise use its best efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable, an earnings statement covering the period of at
least twelve months, but not more than eighteen months, beginning with the first
month after the effective date of the registration statement, which earnings
statement shall satisfy the provisions. of Section 11(a) of the Securities Act;
and

    (j)  In connection with any underwritten offering pursuant to a
registration statement filed pursuant to Section 8.03 hereof, the Company will
enter into an underwriting agreement in form reasonably necessary to effect the

Holders as the Company may request in writing and as shall be reasonably
required in connection with any Registration, qualification or compliance
referred to in this Article 8.

    8.08 INDEMNIFICATION.

    (a)  The Company will indemnify each Holder, each of its officers,
directors and partners, legal counsel, and accountants and each Person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which Registration, qualification, or compliance has been
effected pursuant to this Article 8; and each underwriter, if any, and each
Person who controls within the meaning of Section 15 of the Securities Act any
underwriter, against all expenses, claims, losses, damages, and liabilities (or
actions, proceedings, or settlements in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any prospectus, offering circular, or other document (including any
related registration statement, notification, or the like) incident to any such
registration, qualification, or compliance, or based on any omission (or alleged
omission) to state therein 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 thereunder applicable to
the Company and relating to action or inaction required of the Company in
connection with any such Registration, qualification, or compliance, and will
reimburse each such Holder, each of its officers, directors, partners, legal
counsel, and accountants and each person controlling such Holder, each such
underwriter, and each Person who controls any such





underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating and defending or settling any such claim, loss,
damage, liability, or action, provided that the Company will not be liable in
any such case to the extent that any such claim, loss, damage, liability, or
expense arises out of or is based on any untrue statement or omission based upon
written information furnished to the Company by such Holder or underwriter and
stated to be specifically for use therein.  It is agreed that the indemnity
agreement contained in this Section 8.08(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent has not
been unreasonably withheld).

    (b)  Each Holder will, if Registrable Securities held by such Holder are
included in the securities as to which such Registration, qualification, or
compliance is being effected, indemnify the Company, each of its directors,
officers, partners, legal counsel, and accountants and each underwriter, if any,
of the Company's securities covered by such a registration statement, each
Person who controls the Company of such underwriter within the meaning of
Section 15 of the Securities Act, each other such Holder, and each of their
officers, directors, and partners, and each person controlling such Holder
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular, or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company and such Holders, directors, officers, partners, legal counsel, and
accountants, persons, underwriters, or control persons for any legal or any
other expenses reasonably incurred in connection with investigating or defending
any such claim, loss, damage, liability, or action, in each case to the extent,
but only to the extent, that such untrue statement (or alleged untrue statement)
or omission (or alleged omission) is made in such registration statement,
prospectus, offering circular, or other document in reliance upon and in
conformity with written information furnished to the Company by such Holder and
stated to be specifically for use therein provided, however, that the
obligations of such Holder hereunder shall not apply to amounts paid in
settlement of any such claims, losses, damages, or liabilities (or actions in
respect thereof) if such settlement is effected without the consent of such
Holder (which consent shall not be unreasonably withheld); and provided that in
no event shall any indemnity under this Section 8.08(b) exceed the gross
proceeds from the offering received by such Holder.

    (c)  Each party entitled to indemnification under this Section 8.08 (the
"Indemnified Party") shall give notice to the party required to provide
indemnity (the "Indemnifying Party") promptly





after such Indemnified Party has actual knowledge of any claim as to which
indemnity may be sought, and shall permit the Indemnifying Party to assume the
defense of such claim or any litigation resulting therefrom, provided that
counsel for the Indemnifying Party, who shall conduct the defense of such claim
or any litigation resulting therefrom, shall be approved by the Indemnified
Party (whose approval shall not unreasonably be withheld), and the Indemnified
Party may participate in such defense at such party's expense, and provided
further that the failure of any Indemnified Party to give notice as provided
herein shall not relieve the Indemnifying Party of its obligations under this
Article 8, to the extent such failure is not prejudicial. No Indemnifying Party,
in the defense of any such claim or litigation, shall, except with the consent
of each Indemnified Party, consent to entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation.  Each Indemnified Party shall
furnish such information regarding itself or the claim in question as an
Indemnifying Party may reasonably request in writing and as shall be reasonably
required in connection with defense of such claim and litigation resulting
therefrom.

    (d)  If the indemnification provided for in this Section 8.08 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party hereunder as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations.  The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

    (e)  The obligations of the parties under this Section 8.08 shall survive
the completion of the offering of Registrable Securities under the registration
statement and otherwise.

    8.09 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the date
of this Agreement, the Company shall not, without the prior written consent of a
majority in interest of the Holders, enter into any agreement with any holder or
prospective holder of any securities of the Company giving such holder or
prospective





holder any registration rights the terms of which are more favorable than the
registration rights granted to the Holders hereunder.

    8.10 RULE 144 REPORTING. With a view to making available to the Holders the
benefits of certain rules and regulations of the Commission that may permit the
sale of the Restricted Securities to the public without registration, the
Company agrees, so long as any Holder owns Registrable Securities:

    (a)  Make and keep public information regarding the Company available as
those terms are understood and defined in Rule 144 under the Securities Act, at
all times from and after 90 days following the effective date of the first
Registration under the Securities Act filed by the Company for a public offering
of its securities;

    (b)  File with the Commission in a timely manner all reports and other
documents required of the company under the Securities Act and the Exchange Act
at any time after it has become subject to such reporting requirements;

    (c)  Furnish to the Holder forthwith upon written request a written
statement by the Company as to its compliance with the reporting requirements of
Rule 144 (at any time from and after 90 days following the effective date of the
first registration statement filed by the Company for an offering of its
securities to the general public), and of the Securities Act and the Exchange
Act (at any time after it has become subject to such reporting requirements), a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents so filed as a Holder may reasonably request in
availing itself of any rule or regulation of the Commission allowing a Holder to
sell any such securities without registration.

    8.11 TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS. The rights of any
Holder under this Agreement including, without limitation, the registration
rights under Article 8 and the rights of first refusal under Article 9 may be
transferred or assigned by a Holder only to a transferee or assignee of not less
than 25,000 shares of Registrable Securities (as presently constituted and
subject to    subsequent adjustments for stock splits, stock dividends, reverse
stock splits, and the like), provided that the Company is given written notice
at the time of or within a reasonable time after said transfer or assignment,
stating the name and address of the transferee or assignee and identifying the
securities with respect to which such registration rights are being transferred
or assigned.

    8.12 LOCKUP AGREEMENT. The Holder of each certificate representing
Registrable Securities by acceptance thereof agrees in connection with any
Registration of the Company's securities that,





upon the request of the Company or the underwriter(s) managing any underwritten
offering of the Company's securities, not to sell, make any short sale of, loan,
grant option for the purchase of, or otherwise dispose of any Registrable
Securities (other than those included in such Registration) without the prior
written consent of the Company or such underwriter(s), as the case may be, for
such period of time (not to exceed 180 days) from the effective date of such
Registration as the Company or the underwriter(s) may specify, provided that all
Holders and officers and directors of the Company are bound by and have entered
into similar agreements.  The obligations described in this Section 8.12 shall
not apply to a Registration relating solely to employee benefit plans on Form
S-1 or S-8 or similar forms that may be promulgated in the future or a
Registration relating solely to a Rule 145 transaction on Form S-4 or any
similar form promulgated in the future.

    8.13 ALLOCATION OF REGISTRATION OPPORTUNITIES. In any circumstance in which
all of the Registrable Securities and other shares of Common Stock of the
Company (including shares of Common Stock issued or issuable upon conversion of
shares of any currently unissued series of Preferred Stock of the Company) with
Registration rights (the "Other Shares") requested to be included in a
Registration on behalf of the Holders or other selling stockholders cannot be so
included as a result of limitations on the aggregate number of shares of
Registrable Securities and Other Shares that may be so included, the number of
shares of Registrable Securities and Other Shares that may be so included shall
be allocated among the Holders and other selling stockholders requesting
inclusion of shares pro rata based upon total number of shares requested to be
so included.  In the event a Holder or other selling stockholder subsequently
withdraws or reduces a request for inclusion in such Registration, the number of
shares which may be so included shall be re-allocated in the same manner.  The
Company may not limit the number of Registrable Securities to be included in a
Registration pursuant to this Agreement in order to accommodate the request of
any Significant Stockholder to include more than 25% (prior to the application
of the pro rata allocations provided for above) of the shares of Common Stock
held by such Significant Stockholder, or with respect to Registrations under
Section 8.03 or 8.06 hereof, in order to include in such Registration securities
registered for the Company's own account.

    8.14 DELAY OF REGISTRATION. No Holder shall have any right to take any
action to restrain, enjoin, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Article 8.

    8.15 SUSPENSION OF REGISTRATION RIGHTS. Except as set forth in subparagraph
(b) below, no Holder may request Registration pursuant to Section 8.03 at any
time that all Registrable Securities held by such Holder may immediately be sold
under Rule 144 during any 90-day period, provided, however, that the foregoing
shall not be





applicable in the case of any Holder who owns more than 2% of the outstanding
Common Stock of the Company.

    (b)  The provisions of subparagraph (a) above shall not apply to any Holder
who owns more than 2% of the Company's outstanding Common Stock at the time of

    8.14 PRIOR AGREEMENT. If the Closing occurs, effective from and after the
Closing Date, the provisions of this Article 8 shall supersede the provisions of
Article 8 of the Prior Agreement.

                          ARTICLE 9. RIGHT OF FIRST REFUSAL

    9.01 RIGHT OF FIRST REFUSAL. The Company hereby grants to each Holder who
owns any Registrable Securities the right of first refusal to purchase a pro
rata share of New Securities (as defined in this Section 9.O1) which the Company
may, from time to time, propose to sell and issue.  A Holder's pro rata share,
for purposes of this right of first refusal, is the ratio of the number of
shares of Common Stock owned by such Holder immediately prior to the issuance of
New Securities, assuming full conversion of all outstanding securities
convertible into Common Stock and exercise of any option or warrant to purchase
Common Stock held by said Holder, to the total number of shares of Common Stock
outstanding immediately prior to the issuance of New Securities, assuming full
conversion of all securities convertible into Common Stock and exercise of all
outstanding rights, options and warrants to acquire Common Stock. Each Holder
shall have a right of over-allotment such that if any Holder fails to exercise
its right hereunder to purchase its pro rata share of New Securities, the other
Holders may purchase the non-purchasing Holder's portion on a pro rata basis
within ten days from the date such non-purchasing Holder fails to exercise its
right hereunder to purchase its pro rata share of New Securities. This right of
first refusal shall be subject to the following provisions:

    (a)  "New Securities" shall mean any capital stock (including Common Stock
and/or Preferred Stock) of the Company whether now authorized or not, and
rights, options or warrants to purchase such capital stock, and securities of
any type whatsoever that are, or may become, convertible into capital stock;
provides that the term "New Securities" does not include (1) securities issued
upon exercise of the Series A Warrant, the Series B Warrant or the Series C
Warrant; (2) securities issued upon the exercise of any warrants or options
described in Exhibit E hereto; (3) any borrowings, direct or indirect, from
financial institutions or other Persons by the Company, whether or not presently
authorized, including any type of loan or payment evidenced by any type of debt
instrument, provided such borrowings do not have any equity features including
warrants, options or other rights to purchase capital stock and are not
convertible into capital stock of the Company; (4) not in excess of an aggregate
of 400,000 shares of





Common Stock issued to employees, consultants, officers or directors of the
Company pursuant to any stock option, stock purchase or stock bonus plan,
agreement or arrangement approved by the Board of Directors; (5) securities
issued in connection with any stock split, stock dividend or recapitalization of
the Company; and (6) any right, option or warrant to acquire any security
convertible into the securities excluded from the definition of New Securities
pursuant to subsections (1) through (5) above.

    (b)  In the event the Company proposes to undertake an issuance of New
Securities, it shall give each Holder written notice of its intention,
describing the type of New Securities, and their price and the general terms
upon which the Company proposes to issue the same.  Each Holder shall have 20
days after receipt of such notice to agree to purchase such Holder's pro rata
share of such New Securities for the price and upon the terms specified in the
notice by giving written notice to the Company and stating therein the quantity
of New Securities to be purchased.

    (c)  In the event the Holders fail to exercise the right of first refusal
within said 20-day period and after the expiration of the ten-day period for the
exercise of the over-allotment provisions of this Section 9.01, the Company
shall have 120 days thereafter to sell or enter into an agreement (pursuant to
which the sale of New Securities covered thereby shall be closed, if at all,
within 120 days from the date of said agreement) to sell the New Securities
respecting which the Holders' right of first refusal option set forth in this
Section 9.01 was not exercised, at a price and upon terms no more favorable to
the purchasers thereof than specified in the Company's notice to Holders
pursuant to subsection (b) above. In the event the Company has not sold within
said 120-day period or entered into an agreement to sell the New Securities in
accordance with the foregoing within 120 days from the date of said agreement,
the Company shall not thereafter issue or sell any New Securities, without first
again offering such securities to the Holders in the manner provided in
subsection (b) above.

    (d)  The right of first refusal granted under this Agreement shall expire
upon, and shall not be applicable to, the first Qualified Public Offering
provided that the Holders are offered the opportunity to purchase, in whole or
in part, 10% of the Common Stock being sold in such sale.

    9.02 PRIOR AGREEMENT. If the Closing occurs, effective from and after the
Closing Date, the provisions of this Article 9 shall supersede the provisions of
Article 9 of the Prior Agreement.

                         ARTICLE 10. MISCELLANEOUS PROVISIONS

    10.01     SURVIVAL. All covenants, agreements, representations and
warranties of the Company, the Stockholder and the Purchaser contained in or

Purchased Securities and the Company.

    10.03     NON-WAIVER. No failure by or neglect of any party to this
Agreement in any instance to exercise any right, power or privilege under this
