licenses, permits and other required authorizations from governmental
authorities, necessary to conduct its business as it is now being conducted or
proposed to be conducted and to own or lease the properties and assets it now
owns or holds under lease.  Except where such failure to qualify could not
reasonably be deemed to have a material adverse effect on the Company, the
Company is duly qualified or licensed and in good standing as a foreign
corporation in each jurisdiction wherein the character of its properties or
the nature of the activities conducted by it makes such qualification or
licensing necessary.

     5.2.   Capitalization.  The Company's authorized capitalization is set
forth in the SEC Documents (as defined below). All outstanding securities of

other rights, commitments or arrangements, written or oral, to purchase or

option, warrant or convertible security may be issued in the future, and there
are no voting trusts or agreements, shareholders' agreements, pledge
agreements, buy-sell, rights of first offer, negotiation or refusal or proxies
or similar arrangements relating to any securities of the Company to which the
Company is a party, and to the best knowledge of the Company after due
investigation there are no such trusts, agreement, rights, proxies or similar
arrangements as to which the Company is not a party.  Except as set forth in
the SEC Documents and as contemplated herein, none of the shares of capital
stock of the Company is reserved for any purpose, and the Company is neither
subject to any obligation (contingent or otherwise), nor has any option to

Common Stock and will be free and clear of all liens imposed by or through the
Company. Except as set forth in the SEC Documents, the issuance, sale and
clear delivery of the Bridge Notes, the Bridge Warrants and the Common Stock
or other capital stock of the Company issuable upon the exercise of the Bridge
Warrants and conversion of the Bridge Notes will not be subject to any
preemptive right of shareholders of the Company or to any right of first
refusal or other right in favor of any person.

     5.4.   Authorization; No Breach.  The Company has the full corporate
power and authority to execute, deliver and enter into this Agreement and to
perform its obligations hereunder, and the execution, delivery and performance
of this Agreement, the Bridge Notes, the Bridge Warrants, and any related
financing statement and all other transactions contemplated hereby have been

Securities Exchange Act (as defined in Section 9.8) as the case may be, and
the rules and regulations of the Securities and Exchange Commission thereunder
applicable to such SEC Documents and none of the SEC Documents contained any

required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.  The
financial statements of the Company included in the SEC Documents comply as to
form in all material respects with applicable accounting requirements and with
the published rules and regulations of the Securities and Exchange Commission
with respect thereto, have been prepared in accordance with generally accepted

no actions, suits, proceedings, orders, claims, or, to the Company's
knowledge, investigations pending or, to the Company's knowledge, threatened
against or affecting the Company, at law or in equity or before or by any
federal, state, municipal or other governmental department, commission, board,
bureau, agency or instrumentality; there are no arbitration proceedings
pending under collective bargaining agreements or otherwise; and, to the
knowledge of the Company, there is no basis for any of the foregoing.

     5.8.   Compliance with Law.  To the Company's knowledge, the Company has
complied in all material respects with all applicable statutes and regulations
of the United States and of all states, municipalities and applicable agencies
and foreign jurisdictions or bodies in respect of the conduct of its business
and operations, and the failure, if any, by the Company to have fully complied
with any such statute or regulation does not and will not materially adversely
affect the business or operations of the Company.

     5.9.   Undisclosed Liabilities.  To the Company's knowledge, the Company
has no obligation or liability (whether accrued, absolute, contingent,
unliquidated, or otherwise, whether due or to become due) arising out of
transactions entered into at or prior to the Closing of this Agreement, or any
action or inaction at or prior to the Closing of this Agreement, or any state
of facts existing at or prior to the Closing of this Agreement, except (a)
liabilities reflected on the Company Balance Sheet; (b) liabilities incurred
in the ordinary course of business since the Balance Sheet Date (none of which
is a liability for breach of contract, breach of warranty, torts,
infringements, claims or lawsuits); and (c) liabilities or obligations
disclosed in the SEC Documents.

     5.10.   Disclosure.  Neither this Agreement nor any of the schedules,
exhibits, written statements, documents or certificates prepared or supplied
by the Company with respect to the transactions contemplated hereby contain
any untrue statement of a material fact or omit a material fact necessary to
make the statements contained herein or therein not misleading in light of the
circumstances under which made.  Except as disclosed in the SEC Documents and
except for matters effecting the industry of the Company as a whole, there
exists no fact or circumstance which, to the knowledge of the Company upon due
inquiry, materially adversely affects, or which could reasonably be
anticipated to have a material adverse effect on, the existing or expected
financial condition, operating results, assets, customer relations, employee
relations or business prospects of the Company. The Purchasers acknowledge
that the industry of the Company is subject to extensive regulation by
national, state and local authorities and that a change in any such
regulations or the institution of any litigation effecting the industry of the
Company in general, could have a material adverse effect on the Company.

     5.11.   Compliance with the Securities Laws. Assuming the accuracy and
truth of each of the Purchasers' representations set forth in Section 6 of
this Agreement, all securities of the Company heretofore sold and issued by it
were sold and issued, and the Bridge Notes and the Bridge Warrants were
offered and will be sold and issued, in compliance with all applicable federal
and state securities laws.

     6.   Representations and Warranties of Purchasers.  Each of the
Purchasers hereby severally represents and warrants to the Company as follows:

     6.1.   Investment Intent.  Each of the Purchasers is an "accredited
investor" within the meaning of Regulation D under the Securities Act.  Each
of the Purchasers has experience in making investments in development stage
technology companies and is acquiring the Bridge Notes and the Bridge Warrants
for its own account and not with a present view to, or for sale in connection
with, any distribution thereof in violation of the registration requirements
of the Securities Act.  Each of the Purchasers consents to the placing of a
legend on the certificates representing the Bridge Notes and the Bridge
Warrants to the effect that the shares of Common Stock or other Stock issuable
upon exercise or conversion, as the case may be, of the Bridge Warrants and
the Bridge Notes have not been registered under the Securities Act and may not
be transferred except in accordance with applicable securities laws or an
exception therefrom.

     6.2.   Authorization.  Each of the Purchasers has the power and authority
to execute and deliver this Agreement and to perform its obligations
hereunder, having obtained all required consents, if any, and this Agreement,
when executed and delivered, will constitute a legal valid and binding
obligation of such Purchaser.

     6.3.   Suitability.  Each Purchaser acknowledges that he is a person who
is able to bear the economic risk of this investment and has adequate means of
providing for his current needs and possible personal contingencies with no
need for liquidity of this investment.  In making this statement,
consideration has been given as to whether the Purchaser could afford to hold
his investment in the Company for an indefinite period of time and, whether,
at this time, he could afford a complete loss of his investment, without such
loss affecting his ability to maintain his lifestyle.

     6.4.   Risks.  Each Purchaser acknowledges that this investment is
speculative in nature and involves a high degree of risk, that the Purchaser
may not be able to liquidate this investment and that transferability is
extremely limited.

     6.5.   Due Inquiry.  Each Purchaser acknowledges receipt of all
information regarding the Company which he has requested or desired to know;
that all documents which could be reasonably provided have been made available
for his inspection and review; and that the Purchaser has been afforded the
opportunity to ask questions of and receive answers from duly authorized
officers or other representatives of the Company concerning the Company and an
investment therein, and any additional information which he has requested.

     7.   Covenants of the Company.  Until such time as the Registration
Statement (as defined below) is declared effective under the Securities Act,
the Company covenants and agrees with Purchasers as follows:

     7.1.   Books and Accounts.  The Company will make and keep books, records
and accounts, which, in reasonable detail, accurately and fairly reflect its
transactions, including without limitation, dispositions of its assets.

     7.2.   Reports.  The Company will make such filings as may be required
under the Securities Act.

     7.3.   Use of Proceeds.  The Company shall use the net proceeds from the
sale of the Bridge Notes and Bridge Warrants for its working capital needs.

     7.4.   Corporate Existence, Licenses and Permits; Maintenance of
Properties; New Businesses.  The Company will at all times conduct its
business in the ordinary course and cause to be done all things necessary to
maintain, preserve and renew its existence and will preserve and keep in force
and effect, all licenses, permits and authorizations necessary to the conduct
of its business. The Company will also maintain and keep its properties in
good repair, working order and condition, and from time to time, to make all
needful and proper repairs, renewals and replacements, so that the business
carried on in connection therewith may be properly conducted at all times.

     7.5.   Other Material Obligations.  The Company will comply with (a) all
material obligations which it is subject to, or becomes subject to, pursuant
to any contract or agreement, whether oral or written, as such obligations are
required to be observed or performed, unless and to the extent that the same
are being contested in good faith and by appropriate proceedings and the
Company  has set aside on its books adequate reserves with respect thereto,
and (b) all applicable laws, rules, and regulations of all governmental
authorities, the violation of which could have a material adverse effect upon
the business of the Company.

     7.6.   Amendment to the Articles of Incorporation and the By-Laws.  The
Company will perform and be in compliance with and observe all of the
provisions set forth in its Articles of Incorporation and By-Laws to the
extent that the performance of such obligations is legally permissible;
provided that the fact that performance is not legally permissible will not
prevent such nonperformance from constituting an event of default under this
Agreement.  The Company will not amend its Articles of Incorporation or
By-Laws so as to adversely affect the rights of the Purchasers under this
Agreement, the Articles of Incorporation, the By-Laws, the Bridge Warrants or
the Bridge Notes.

     7.7.   Dividends; Distributions; Repurchases of Common Stock; Treasury
Stock.  The Company shall not declare or pay any dividends on, or make any
other distribution with respect to, its capital stock, whether now or
hereafter outstanding, or purchase, acquire, redeem or retire any shares of
its capital stock, without the prior written consent of the Purchasers,
provided, however, the foregoing shall not prohibit the Company issuing shares
of its capital stock in exchange for extinguishing debt owed to any person, or
from repurchasing any shares of its Common Stock from any present or former
officer, Director or employee of the Company, or from repurchasing any
outstanding warrants.

     7.8.   Taxes and Liens.  The Company will duly pay and discharge when
payable, all taxes, assessments and governmental charges imposed upon or
against the Company or its properties, or any part thereof or upon the income
or profits therefrom, in each case before the same become delinquent and
before penalties accrue thereon, as well as all claims for labor, materials or
supplies which if unpaid might by law become a lien upon any of its property,
unless and to the extent that the same are being contested in good faith and
by appropriate proceedings and the Company has set aside on its books adequate
reserves with respect thereto.

     7.9.   Restrictive Agreement.  The Company covenants and agrees that
subsequent to the Closing, it will not be a party to any agreement or
instrument which by its terms would restrict the Company's performance of its
obligations pursuant to this Agreement, the Articles of Incorporation,
By-laws, the Bridge Warrants or the Bridge Notes.

     8.   Registration of Common Stock.

     8.1.   Registration.  Not later than nine months following the Final
Closing Date, the Company will file a registration statement (the
"Registration Statement") with respect to the resale of the Registrable
Securities with the Securities and Exchange Commission.  The Company will use
commercially reasonable efforts to effect,  no later than 12 months following
the Final Closing Date, the registrations, qualifications or compliances
(including, without limitation, the execution of any required undertaking to
file post-effective amendments, appropriate qualifications under applicable
blue sky or other state securities laws and appropriate compliance with
applicable securities laws, requirements or regulations) as may be reasonably
requested and as would permit or facilitate the sale and distribution of all
Registrable Securities until the distribution thereof is complete. In the
event the Registration Statement has not been declared effective under the
Securities Act within 12 months of the Final Closing Date, then, for each 90
days thereafter that the Registration Statement has not been declared
effective, the Company shall pay a penalty to each of the Purchasers equal to
5% of the principal amount of the Bridge Notes held by it. This penalty, which
shall be payable at the Company's option in either cash or shares of
registered Common Stock, shall be paid by the Company to the Purchasers within
10 days following the effective date of the Registration Statement, or, in the
event the Registration Statement has still not been declared effective or has
been withdrawn by the Company, no later than the second anniversary of the
Final Closing Date. No penalties will accrue under this Section 8.1 after the
earliest date on which the Registrable Securities cease to be Registrable
Securities.

     8.2.   Registration Procedures.  In connection with the registration of
any Registrable Securities under the Securities Act as provided in this
Section 8, the Company will use its best efforts, as expeditiously as possible
to:

          (a)   Prepare and file with the Securities and Exchange Commission
the Registration Statement with respect to such Registrable Securities and use
its best efforts to cause such Registration Statement to become effective;

          (b)   Prepare and file with the Securities and Exchange Commission
such amendments and supplements to such Registration Statement and the
prospectus used in connection therewith as may be necessary to keep such
Registration Statement effective until the earlier to occur of December 31,
2005 or such time as the Bridge Warrants have been redeemed pursuant to the
terms therein, and to comply with the provisions of the Securities Act (to the
extent applicable to the Company) with respect thereto;

          (c)   Furnish to each seller of such Registrable Securities such
number of copies of such Registration Statement and of each such amendment and
supplement thereto (in each case including all exhibits), such number of
copies of the prospectus included in such Registration Statement (including
each preliminary prospectus), in conformity with the requirements of the
Securities Act, and such other documents, as such seller may reasonably
request, in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          (d)   Use its best efforts to register or qualify such Registrable
Securities covered by such Registration Statement under such other securities
or blue sky laws of such jurisdictions as any seller reasonably requests, and
do any and all other acts and things which may be reasonably necessary or
advisable to enable such seller to consummate the disposition in such
jurisdictions of the Registrable Securities owned by such seller, except that
the Company will not for any such purpose be required to qualify generally to
do business as a foreign corporation in any jurisdiction wherein it would not,
but for the requirements of this Section 8.2(d) be obligated to be qualified,
to subject itself to taxation in any such jurisdiction, or to consent to
general service of process in any such jurisdiction;

          (e)   Provide a transfer agent and registrar for all such
Registrable Securities covered by such Registration Statement not later than
the effective date of such Registration Statement;

          (f)   Notify each seller of such Registrable Securities 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 contains an untrue
statement of a material fact or omits any fact necessary to make the
statements therein not misleading, and, at the request of any such seller, the
Company will prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such
prospectus will not contain an untrue statement of a material fact or omit to
state any fact necessary to make the statements therein not misleading;

          (g)   Cause all such Registrable Securities to be listed on each
securities exchange or quoted on each automated over-the-counter trading
system on which similar securities issued by the Company are then listed or
quoted, as applicable;

          (h)   Enter into such customary agreements and take all such other
actions as reasonably required in order to expedite or facilitate the
disposition of such Registrable Securities; and

          (i)   Make available for inspection by any seller of Registrable
Securities, all financial and other records, pertinent corporation documents
and properties of the Company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such seller in
connection with the Registration Statement pursuant to Section 8.1.

     8.3.   Registration and Selling Expenses.

          (a)   All expenses incurred by the Company in connection with the
Company's performance of or compliance with this Section 8, including, without
limitation (i) all registration and filing fees (including all expenses
incident to filing with the National Association of Securities Dealers, Inc.),
(ii) blue sky fees and expenses, (iii) all necessary printing and duplicating
expenses and (iv) all fees and disbursements of counsel and accountants for
the Company (including the expenses of any audit of financial statements),
retained by the Company (all such expenses being herein called "Registration
Expenses"), will be paid by the Company except as otherwise expressly provided
in this Section 8.3. The term "Registration Expenses" shall not include any
underwriting discounts or commissions incurred by a Purchaser, which shall be
the responsibility of such Purchaser.

          (b)   The Company will, in any event, in connection with any
registration statement, pay its internal expenses (including, without
limitation, all salaries and expenses of its officers and employees performing
legal, accounting or other duties in connection therewith and expenses of
audits of year-end financial statements), the expense of liability insurance
and the expenses and fees for listing the securities to be registered on one
or more securities exchanges or automated over-the-counter trading systems on
which similar securities issued by the Company are then listed.

     8.4.   NASD.  In the event any Purchaser is deemed to be a member or an
affiliate of a member of the National Association of Securities Dealers, Inc.
("NASD") and as a result the Registrable Securities held by such Purchaser
cannot be included in the Registration Statement, then such Purchaser shall no
longer be entitled to the registration rights granted under this Section 8.
The Company may, however, in its sole discretion, include the Purchaser's
Registrable Securities in a future registration statement, to the extent
permitted by the NASD or the Securities and Exchange Commission.

     8.5.   Indemnification.

          (a)   The Company hereby agrees to indemnify, to the extent
permitted by law, each holder of Registrable Securities, its officers and
directors, if any, and each person, if any, who controls such holder within
the meaning of the Securities Act, against all losses, claims, damages,
liabilities and expenses (under the Securities Act or common law or otherwise)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus (and as amended or
supplemented if the Company has furnished any amendments or supplements
thereto) or any preliminary prospectus, which registration statement,
prospectus or preliminary prospectus shall be prepared in connection with the
registration contemplated by this Section 8, or caused by 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, except
insofar as such losses, claims, damages, liabilities or expenses are caused by
any untrue statement or alleged untrue statement contained in or by any
omission or alleged omission from information furnished in writing by such
holder to the Company in connection with the registration contemplated by this
Section 8, provided the Company will not be liable pursuant to this Section
8.5 if such losses, claims, damages, liabilities or expenses have been caused
by any selling security holder's failure to deliver a copy of the registration
statement or prospectus, or any amendments or supplements thereto, after the
Company has furnished such holder with the number of copies required by
Section 8.2(c).

          (b)   In connection with any registration statement in which a
holder of Registrable Securities is participating, each such holder shall
furnish to the Company in writing such information as is reasonably requested
by the Company for use in any such registration statement or prospectus and
shall severally, but not jointly,  indemnify, to the extent permitted by law,
the Company, its directors and officers and each person, if any, who controls
the Company within the meaning of the Securities Act, against any losses,
claims, damages, liabilities and expenses resulting from any untrue statement
or alleged untrue statement of a material fact or any omission or alleged
omission of a material fact required to be stated in the registration
statement or prospectus or any amendment thereof or supplement thereto or
necessary to make the statements therein not misleading, but only to the
extent such losses, claims, damages, liabilities or expenses are caused by an
untrue statement or alleged untrue statement contained in or by an omission or
alleged omission from information so furnished in writing by such holder in
connection with the registration contemplated by this Section 8. If the
offering pursuant to any such registration is made through underwriters, each
such holder agrees to enter into an underwriting agreement in customary form
with such underwriters and to indemnify such underwriters, their officers and
directors, if any, and each person who controls such underwriters within the
meaning of the Securities Act to the same extent as hereinabove provided with
respect to indemnification by such holder of the Company.  Notwithstanding the
foregoing or any other provision of this Agreement, in no event shall a holder
of Registrable Securities be liable for any such losses, claims, damages,
liabilities or expenses in excess of the net proceeds received by such holder
in the offering.

          (c)   Promptly after receipt by an indemnified party under Section
8.5 (a) or (b) of notice of the commencement of any action or proceeding, such
indemnified party will, if a claim in respect thereof is made against the
indemnifying party under such Section, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party will not relieve it from any liability which it may have to
any indemnified party otherwise than under such Section. In case any such
action or proceeding is brought against any indemnified party, and it notifies
the indemnifying party of the commencement thereof, the indemnifying party
will be entitled to participate therein, and, to the extent that it wishes,
jointly with any other indemnifying party similarly notified, to assume the
defense thereof, with counsel approved by such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election
so to assume the defense thereof, the indemnifying party will not be liable to
such indemnified party under such Section for any legal or any other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof (other than reasonable costs of investigation) unless incurred at the
written request of the indemnifying party. Notwithstanding the above, the
indemnified party will have the right to employ counsel of its own choice in
any such action or proceeding if the indemnified party has reasonably
concluded that there may be defenses available to it which are different from
or additional to those of the indemnifying party, or counsel to the
indemnified party is of the opinion that it would not be desirable for the
same counsel to represent both the indemnifying party and the indemnified
party because such representation might result in a conflict of interest (in
either of which cases the indemnifying party will not have the right to assume
the defense of any such action or proceeding on behalf of the indemnified
party or parties and such legal and other expenses will be borne by the
indemnifying party). An indemnifying party will not be liable to any
indemnified party for any settlement of any such action or proceeding effected
without the consent of such indemnifying party.

          (d)   If the indemnification provided for in Section 8.5(a) or (b)
is unavailable under applicable law to an indemnified party in respect of any
losses, claims, damages or liabilities referred to therein, then each
applicable indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities in such proportion as is
appropriate to reflect the relative fault of the Company on the one hand and
of the holders of Registrable Securities on the other in connection with the
statements or omissions which resulted in such losses, claims, damages, or
liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company on the one hand and of the holders of
Registrable Securities on the other 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 Company or by the holders of Registrable Securities and the parties'
relative intent, knowledge, access to information and opportunity to correct
or prevent such statement or omission. The amount paid or payable by a party
as a result of the losses, claims, damages and liabilities referred to above
shall be deemed to include, subject to the limitations set forth in Section
8.5(c), any legal or other fees or expenses reasonably incurred by such party
in connection with investigating or defending any action or claim. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) will be entitled to contribution from any person who is
not guilty of such fraudulent misrepresentation.

          (e)   Promptly after receipt by the Company or any holder of
Securities of notice of the commencement of any action or proceeding, such
party will, if a claim for contribution in respect thereof is to be made
against another party (the "contributing party"), notify the contributing
party of the commencement thereof; but the omission so to notify the
contributing party will not relieve it from any liability which it may have to
any other party other than for contribution hereunder. In case any such
action, suit, or proceeding is brought against any party, and such party
notifies a contributing party of the commencement thereof, the contributing
party will be entitled to participate therein with the notifying party and any
other contributing party similarly notified.

the third Arbitrator within thirty (30) days of any request for Arbitration,
such Arbitrator shall be selected by the AAA, upon application of the Company
or the Majority Purchasers.  The persons selected as Arbitrators need not be
professional arbitrators, and persons such as lawyers, accountants, brokers
and bankers shall be acceptable.  Before undertaking to resolve the dispute,
each of the Arbitrators shall be duly sworn faithfully and fairly to hear and
examine the matters in controversy and to make a just award according to the
