Reports, the Company has good and marketable title to, or valid leasehold
interests in, all of the material assets and properties used or useful by the
Company in the Business (collectively, the "Properties and Facilities"). All of

Property of any other person or entity. The transactions contemplated under this

in the Intellectual Property. The Company has taken commercially reasonable
measures to protect the proprietary nature of the Intellectual Property and to
maintain in confidence all trade secrets and confidential information owned or
used by the Company.

<PAGE>
There are no legal or governmental proceedings, including interference,
re-examination, reissue, opposition, nullity, or cancellation proceedings
pending that relate to any of the Intellectual Property, other than review of
pending patent applications, and the Company is not aware of any information
indicating that such proceedings are threatened or contemplated by any
governmental entity or any other Person.

The Company is not aware that any of its employees or independent contractors is
obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement, or subject to any judgment, decree or order of
any court or administrative agency, that would interfere with the use of such
employee's or independent contractor's best efforts to promote the interest of
the Company or that would conflict with the Company's business as now conducted
or as proposed to be conducted. Neither the execution or delivery of this
Agreement, nor the carrying on of the Company's business by the employees and
independent contractors of the Company, nor the conduct of the Company's
business as now conducted, or as currently proposed to be conducted, will, to
the Company's knowledge, conflict with or result in a breach of the terms,
conditions, or provisions of, or constitute a default under, any contract,
covenant or instrument under which any such employee or independent contractor
is now obligated. It is not and will not be necessary to use any inventions of
any of the Company's employees (or persons the Company currently intends to
hire) made prior to their employment by the Company. All of the Company's
significant employees have executed Confidential Information and Invention
Assignment Agreements with the Company. To the knowledge of the Company, no key
employee of the Company is in violation of any term of any employment contract,
patent disclosure agreement, proprietary information agreement, noncompetition
agreement, or any other contract or agreement or any restrictive covenant
relating to the right of any such key employee to be employed by the Company
because of the nature of the business conducted or to be conducted by the
Company or relating to the use of trade secrets or proprietary information of

                               REGISTRATION RIGHTS

     7.1 Mandatory Registration. The Company shall prepare and file a
registration statement with the SEC on or before August 13, 2005 (the "Filing
Date") covering the resale of all of the Registrable Securities. The Company
shall use its best efforts to obtain effectiveness of the registration statement
as soon as practicable. If the registration statement is not filed by the Filing
Date or the registration statement is not declared effective by the SEC on or
before October 2, 2005, or after the registration statement has been declared
effective, sales of all of the Registrable Securities cannot be made pursuant to
the registration statement ( any such failure or breach being referred to as an
"Event," and the date on which such Event occurs being referred to as the "Event
Date"), then in addition to any other rights the Purchaser may have hereunder or
under applicable law, the Company will make a payment to the Purchaser as
liquidated damages and not as a penalty, (a) an amount equal to 2% of the
Investment Amount paid by the Purchaser for the shares of Common Stock that are
still owned by the Purchaser on the Event Date; and (b) 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 the Purchaser an amount equal to 2% of the Investment Amount paid by the
Purchaser for the shares of Common Stock that are still owned by the Purchaser
on each such monthly anniversary of the Event Date. If the Company fails to pay
any liquidated damages pursuant to this Section 7.1 in full within five business
days after the end of the month of the date payable, the Company will pay
interest at the rate of 10% per annum to the Holder. At the option of the
Company, any amounts payable to the Purchaser pursuant to this Section 7.1 may
be paid in cash or in shares of the Common Stock. If paid in Common Stock , the
shares shall be valued at the average of the closing prices of the Common Stock
for the ten Trading Days prior to (but not including) the date such liquidated
damages are due. The liquidated damages shall apply on a pro-rata basis for any
portion of a month prior to the cure of an Event, except in the case of the
first Event Date. Notwithstanding the foregoing, in no event shall the payments
to which a Purchaser is entitled pursuant to this Section 7.1 exceed 20% of the
Investment Amount paid by such Purchaser.

     7.2 Piggyback Registrations.

          (a) Whenever the Company proposes to register any of its securities
under the Securities Act and the registration form to be used may be used for
the registration of Registrable Securities (a "Piggyback Registration"), the
Company will give prompt written notice (in any event within three (3) Business
Days after its receipt of notice of any exercise of demand registration rights
other than under this Agreement) to all holders of Registrable Securities with
respect of the proposed offering at least 15 days before the initial filing with
the SEC of such registration statement, and offer to include in such filing such
Registrable Securities as any such holder may request. Each such holder of
Registrable Securities desiring to have Registrable Securities registered under
this Section 7.2 shall advise the Company in writing within 15 days after the
date of receipt of such notice from the Company, setting forth the amount of
such Registrable Securities for which registration is requested. The Company
shall thereupon include in such filing the number of Registrable Securities for
which registration is so requested, and shall use its best efforts to effect
registration under the Securities Act of such Registrable Securities.

                                      -17-
<PAGE>
          (b) The registration expenses of the holders of Registrable Securities
will be paid by the Company in all Piggyback Registrations to the extent
provided in Section 7.5 hereof.

          (c) If a Piggyback Registration is an underwritten primary
registration on behalf of holders of the Company's securities, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the Company, the Company will include in such registration: (i)
first, the securities the Company proposes to sell, and (ii) second, the
Registrable Securities requested to be included in such registration, pro rata
among the holders of the securities requested to be included in such
registration.

          (d) If a Piggyback Registration is an underwritten secondary
registration on behalf of holders of the Company's securities, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number that
can be sold in an orderly manner in such offering within a price range
acceptable to the holders initially requesting such registration, the Company
will include in such registration, the Registrable Securities requested to be
included in such registration, pro rata among the holders of other securities
requested to be included in such registration.

     7.3 Demand Registration Rights.

          (a) If, at any time prior to December 31, 2007, the Company receives a
written request by the holders of a majority of the Registrable Securities to
effect the registration under the Securities Act of the Registrable Securities,
the Company shall follow the procedures described in this Section 7.3. Within
five (5) days of its receipt of such request, the Company shall give written
notice of such proposed registration (a "Demand Registration") to all holders of
Registrable Securities, and thereupon, the Company shall, as expeditiously as
possible, use its best efforts to effect the registration on a form of general
use under the Securities Act of the shares it has been requested to register in
such initial request and in any response to such notice given to the Company
within 20 days after the Company's giving of such notice; provided, however,
that the Company shall not be required to effect more than one Demand
Registration pursuant to this Section 7.3.

          (b) The Company may not be required to effect a registration pursuant
to this Section 7.3 during the first 180 days after the effective date of any
registration statement filed by the Company under Sections 7.1 or 7.2 hereof if
the holders of Registrable Securities requesting registration have been afforded
the opportunity to register in such registration all or a majority of their
Registrable Securities.

                                      -18-
<PAGE>
          (c) The Company may include in any registration under this Section 7.3
any other shares of Common Stock (including issued and outstanding shares of
stock as to which the holders thereof have contracted with the Company for
"piggyback" registration rights) so long as the inclusion in such registration
of such shares will not, in the opinion of the managing underwriter of the
shares of the stockholder or stockholders first demanding registration (if the
offering is underwritten), interfere with the successful marketing in accordance
with the intended method of sale or other disposition of all the stock sought to
be registered by such demanding stockholder or stockholders pursuant to this
Section 7.3.

     7.4 Registration Procedures. Whenever the holders of Registrable Securities
have requested that any Registrable Securities be registered pursuant to this
Agreement, the Company will use reasonable efforts to effect the registration
and the sale of such Registrable Securities in accordance with the intended
method of disposition thereof, and pursuant thereto the Company will as
expeditiously as possible:

          (a) prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use reasonable efforts to cause such
registration statement to become effective;

          (b) prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be reasonably necessary to keep such registration statement effective for a
period equal to the shorter of (i) one year and (ii) the time by which all
securities covered by such registration statement have been sold;

          (c) furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto,
the prospectus included in such registration statement (including each
preliminary prospectus) 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 reasonable efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any seller of Registrable Securities 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 (provided that the Company will not
be required to (i) qualify generally to do business in any jurisdiction where it
would not otherwise be required to qualify but for this subparagraph, (ii)
subject itself to taxation in any such jurisdictions, (iii) consent to general
service of process in each such jurisdiction, (iv) undertake such actions in any
jurisdiction other than the states of the United States of America and the
District of Columbia, or (v) register or qualify such Registrable Securities in
any state where the cost to do would be prohibitively expensive);

          (e) 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 Purchaser 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;

                                      -19-
<PAGE>
          (f) provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (g) enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities (including, without limitation, effecting a stock split
or a combination of shares);

          (h) make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement;

          (i) otherwise use its best efforts to comply with all applicable rules
and regulations of the SEC, and make available to its security holders, as soon
as reasonably practicable, an earnings statement covering the period of at least
twelve months beginning with the first day of the Company's first full calendar
quarter after the effective date of the registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder;

          (j) permit any holder of Registrable Securities which holder, in its
sole and exclusive judgment, might be deemed to be an underwriter or a
controlling person of the Company, to participate in the preparation of such
registration or comparable statement and to require the insertion therein of
material, furnished to the Company in writing, which in the reasonable judgment
of such holder and its counsel should be included; and

          (k) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Common Stock included in such registration statement for sale in any
jurisdiction, the Company will use its best efforts promptly to obtain the
withdrawal of such order. If any such registration or comparable statement
refers to any holder by name or otherwise as the holder of any securities of the
Company and if in its sole and exclusive judgment such holder is or might be
deemed to be a controlling person of the Company, such holder shall have the
right to require (i) the insertion therein of language, in form and substance
satisfactory to such holder and presented to the Company in writing, to the
effect that the holding by such holder of such securities is not to be construed
as a recommendation by such holder of the investment quality of the Company's
securities covered thereby and that such holding does not imply that such holder
will assist in meeting any future financial requirements of the Company, (ii) in
the event that such reference to such holder by name or otherwise is not
required by the Securities Act or any similar federal statute then in force, the
deletion of the reference to such holder; provided that with respect to this
clause (ii) such holder shall furnish to the Company an opinion of counsel to
such effect, which opinion and counsel shall be reasonably satisfactory to the
Company.

performance of or compliance with this Article 7, including without limitation
all registration and filing fees, fees and expenses of compliance with
securities or blue sky laws, printing expenses, messenger and delivery expenses,
and fees and disbursements of counsel for the Company and all independent
certified public accountants, and other Persons retained by the Company (all
such expenses, other than discounts and commissions related to sales by the

Company.

     7.6 Indemnification.

          (a) The Company agrees to indemnify, to the extent permitted by law,
each holder of Registrable Securities, its partners, officers and directors and
each Person who controls such holder (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities and expenses caused by any
untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as the same are caused by or contained in any
information furnished in writing to the Company by such holder expressly for use
therein or by such 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 a sufficient number of copies of the
same. In connection with an underwritten offering, the Company will indemnify
such underwriters, their officers and directors and each Person who controls
such underwriters (within the meaning of the Securities Act) to the same extent
as provided above with respect to the indemnification of the holders of
Registrable Securities.

          (b) In connection with any registration statement in which a holder of
Registrable Securities is participating, each such holder will furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, will indemnify the Company, its
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses resulting from any untrue or alleged untrue statement of material
fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading but only to the extent that such
untrue statement or omission is contained in any information or affidavit so
furnished in writing by such holder;

                                      -21-

          (c) Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

          (d) The indemnification provided for under this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and will survive the transfer of securities. The Company also
agrees to make such provisions, as are reasonably requested by any indemnified
party, for contribution to such party in the event the Company's indemnification
is unavailable for any reason.

     7.7 Participation in Underwritten Registrations. No Person may participate
in any registration hereunder which is underwritten unless such Person (a)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements; provided that no
holder of Registrable Securities included in any underwritten registration shall
be required to make any representations or warranties to the Company or the
underwriters other than representations and warranties regarding such holder and
such holder's intended method of distribution.

     7.8 Termination of Registration Rights. All registration rights granted
under this Article 7 will expire if the Company is subject to the provisions of
the Securities Exchange Act and all of the holder's Registrable Securities may
be sold under SEC Rule 144 during any ninety-day period.

                                   ARTICLE 8

failure in exercising any right, power or remedy hereunder shall affect or

remedy preclude any further exercise thereof or of any other right, power or
remedy. The rights and remedies hereunder are cumulative and not exclusive of
any rights or remedies that the Purchaser or any holder of Warrants or
Underlying Common Stock would otherwise have. Any waiver, permit, consent or

writing, and shall be effective only to the extent in such writing specifically
set forth.

     8.4 Fees and Expenses. Each party shall pay the fees and expenses of its

     8.10 Remedies. In addition to being entitled to exercise all rights

any liabilities of such Purchaser.

by or invalid under applicable law in any jurisdiction, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without

shall together constitute one and the same instrument.

     8.15 Integration. This Agreement and the other Purchase Documents set forth
the entire understanding of the parties hereto with respect to all matters
contemplated hereby and supersede all previous agreements and understandings
among them concerning such matters. No statements or agreements, oral or
written, made prior to or at the signing hereof, shall vary, waive or modify the
written terms hereof.

acknowledges that it has sole responsibility for its own due diligence
investigation and its own investment decision and that in connection with its
investigation and its investment decision (i) such Purchaser has not relied on
