corporation to transact business and is in good standing in each jurisdiction in

qualified or be in good standing would not have a material adverse effect on the
Company.

its business as currently conducted. Each Subsidiary is duly qualified as a
foreign corporation to transact business and is in good standing in each
jurisdiction in which the conduct of its business or the ownership or leasing of

authorized and, when issued and sold and paid for by the Purchasers in
accordance with the terms of this Agreement and the Designation, will be duly
authorized, validly issued, fully paid and non assessable, and the Purchasers

authorized and reserved and, when issued upon conversion of the Shares in
accordance with the terms of the Designation, will be validly issued, fully paid
and non-assessable, and the issuance of the Conversion Shares and Dividend

any security of the Company.

            3.9 The Company has not granted or agreed to grant to any person any

the Company registered with the SEC or any other governmental authority that
have not been satisfied or waived.

policy.

            3.11 The execution and delivery by the Company, and the performance
by the Company of its obligations under the Transaction Documents will not
conflict with or contravene in any material respect, cause a breach or violation
of or default under, any provision of applicable law or the certificate of
incorporation or by-laws of the Company or any agreement or other instrument
binding upon the Company or any Subsidiary that is material to the Company and
the Subsidiaries, taken as a whole, for which a waiver or consent has not been
obtained, or any judgment, order or decree of any governmental body, agency or
court having jurisdiction over the Company, or any Subsidiary, and no consent,
approval, authorization or order of, or qualification with, any governmental
body or agency is required for the performance by the Company of its obligations
under the Transaction Documents, except such as may be required by the

and sale of the Shares and by Federal and state securities laws with respect to
the obligations of the Company under the Registration Rights Agreement or as may

Company and the Subsidiaries taken as a whole.

            3.12 There has not occurred any material adverse change, or any

charter or by-laws or in default in the performance of any obligation,
agreement, covenant or condition contained in any indenture, loan agreement,
mortgage, lease or other agreement or instrument that is material to the Company
and the Subsidiaries taken as a whole to which the Company or any Subsidiary is
a party or by which the Company or any Subsidiary or any of their properties is

a material adverse effect on the Company and the Subsidiaries taken as a whole.

judgments, writs, injunctions, decrees or demands pending or, to the Company's
knowledge, threatened to which the Company or any Subsidiary is a party or to

than proceedings, orders, judgments, writs, injunctions, decrees or demands
accurately described in all material respects in the Memorandum and proceedings,
orders, judgments, writs, injunctions, decrees or demands that would not have a

such noncompliance with Environmental Laws, failure to receive required permits,
licenses or other approvals, or noncompliance with ERISA or the Foreign Corrupt
Practices Act or failure to comply with the terms and conditions of such
permits, licenses or approvals, would not, singly or in the aggregate, have a
material adverse effect on the Company and the Subsidiaries, taken as a whole.

            3.16 There are no costs or liabilities to the Company or any
Subsidiary associated with Environmental Laws (including, without limitation,
any capital or operating expenditures required for clean-up, closure of
properties or compliance with Environmental Laws or any permit, license or
approval, any related constraints on operating activities and any potential

material adverse effect on the Company and the Subsidiaries taken as a whole.

            3.17 None of the Company nor any Subsidiary is, and giving effect to
the offering and sale of the Shares and the application of the proceeds thereof

            3.20 Each of the Company and each Subsidiary owns or possesses, or
has the right to use, all material patents, patent rights, licenses, inventions,
copyrights, know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures),
trademarks, service marks and trade names currently employed or required by it
in connection with the business currently conducted by it as described in the
Memorandum, except such as the failure to so own or possess or have the right to
use would not have, singly or in the aggregate, a material adverse affect on the
Company and the Subsidiaries taken as a whole. To the Company's knowledge, there
are no valid and enforceable United States patents that are infringed by the
business currently conducted by the Company or any Subsidiary, or as currently
proposed to be conducted by the Company or any Subsidiary, as described in the
Memorandum and which infringement would have a material adverse effect on the
Company and the Subsidiaries taken as a whole. The Company is not aware of any
basis for a finding that the Company does not have valid title or license rights
to the patents and patent applications referenced in the Memorandum as owned or
licensed by the Company or any Subsidiary, and, to the Company's knowledge, none
of the Company nor any Subsidiary is subject to any judgment, order, writ,
injunction or decree of any court or any Federal, state, local, foreign or other
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, or any arbitrator, nor has it entered into or is it a party
to any contract, which restricts or impairs the use of any of the foregoing
which would have a material adverse effect on the Company and the Subsidiaries
taken as a whole. Neither the Company nor any Subsidiary has received any
written notice of infringement of or conflict with asserted rights of any third
party with respect to the business currently conducted by it as described in the
Memorandum and which would have a material adverse effect on the Company and the
Subsidiaries taken as a whole and the Company has no knowledge of any facts or
circumstances that would serve as a reasonable basis for any such claims.

            3.21 Other than with respect to Environmental Laws and ERISA (which
are governed by Section 3.15 above) each of the Company and each Subsidiary has
such permits, licenses, consents, exemptions, franchises, authorizations and
other approvals (each, an "Authorization") of, and has made all filings with and
notices to, all appropriate federal, state, local or foreign governmental or
regulatory authorities and self regulatory organizations and all courts and
other tribunals, as are necessary to own, lease, license and operate its
respective properties and to conduct its business, except to the extent the
failure to have any such Authorization or to make any such filing or notice
would not, singly or in the aggregate, have a material adverse effect on the
Company and the Subsidiaries taken as a whole. Each such Authorization is valid
and in full force and effect and the Company and each Subsidiary is in
compliance with all the material terms and conditions thereof and with the rules
and regulations of the authorities and governing bodies having jurisdiction with
respect thereto, and no event has occurred (including, without limitation, the
receipt of any notice from any authority or governing body) which allows or,

                                       7
<PAGE>

after notice or lapse of time or both, would allow, revocation, suspension or
termination of any such Authorization or results or, after notice or lapse of
time or both, would result in any other impairment of the rights of the holder
of any such Authorization except to the extent such failure to be valid and in
full force and effect or to be in compliance, the occurrence of any such event
or the presence of any such restriction would not, singly or in the aggregate,
have a material adverse effect on the Company and the Subsidiaries taken as a
whole.

            3.22 There are no outstanding rights, warrants, options, convertible
securities or commitments to sell granted or issued by the Company entitling any
person to purchase or otherwise acquire any shares of the capital stock of the
Company, except as otherwise disclosed in the Memorandum and the Incorporated
Documents and except for options granted to directors and employees of the
Company in the ordinary course of business since June 30, 2005.

            3.23 The financial statements included or incorporated by reference
in the Memorandum as the same may have been amended prior to the date of the
Memorandum, together with related schedules and notes, present fairly in all
material respects the financial position, results of operations and changes in
financial position of the Company and its consolidated subsidiaries on the basis
stated therein at the respective dates or for the respective periods to which
they apply; such statements and related schedules and notes have been prepared
in accordance with generally accepted accounting principles consistently applied
throughout the periods involved, except as disclosed therein; and the other
financial and statistical information and data set forth in the Memorandum are,
in all material respects, accurately presented and prepared on a basis
consistent with such financial statements and the books and records of the
Company. The financial information set forth under the captions "Summary
Financial Data" and "Capitalization" in the Memorandum are derived from the
accounting records of the Company and its subsidiaries, have been computed on a
basis consistent with the audited financial statements in the Memorandum and
fairly present in all material respects, on the basis stated in the Memorandum,
the information included therein.

            3.24 There are no existing or, to the Company's knowledge,
threatened labor disputes with the employees of the Company or any Subsidiary
which would have a material adverse effect on the Company and the Subsidiaries
taken as a whole.

            3.25 The Company's and the Subsidiaries' manufacturing, distribution
and marketing practices are in compliance with all applicable laws, rules,
regulations, orders, licenses, judgments, writs, injunctions and decrees in each
country in which the Company's and the Subsidiaries' products are marketed,
except for such noncompliances that would not have a material adverse effect on
the Company and the Subsidiaries taken as a whole.

            3.26 None of the Company nor any Subsidiary has received any written
communication notifying the Company or such Subsidiary as to the termination or
threatened termination or modification or threatened modification of any
consulting, licensing, marketing, research and development, cooperative or any
similar agreement described in the Memorandum.

            3.27 The statements relating to legal matters, documents or
proceedings included in the Memorandum under the captions "Description of
Capital Stock" and "Notice to Investors" and in "Item 3 - Legal Proceedings" of
the Company's most recent annual report on Form 10-K and in "Item 1 - Legal
Proceedings" of the Company's quarterly reports on Form 10-Q included or
incorporated by reference in the Memorandum fairly summarize in all material
respects such matters, documents or proceedings.

                                       8
<PAGE>

            3.28 Neither the Company nor any Subsidiary, nor to the Company's
knowledge, any of its officers, directors or Affiliates has taken, directly or
indirectly, any action designed to or which has constituted the stabilization or
manipulation of the price of the common stock of the Company or any security
convertible into or exchangeable for common stock of the Company to facilitate
the sale or resale of any of the Preferred Stock.

            3.29 Each of the Company and each Subsidiary has filed all Federal,
state, local and foreign tax returns which are required to be filed through the
date hereof (except where the failure to so file would not have a material
adverse effect on the Company and the Subsidiaries taken as a whole), which
returns are true and correct in all material respects, or have received
extensions thereof, and have paid all taxes shown on such returns and all
assessments received by them to the extent that the same are material and have
become due. All tax liabilities are adequately provided for on the books of the
Company and the Subsidiaries. To the Company's knowledge, there are no tax
audits or investigations pending, which if adversely determined, would have a
material adverse effect on the Company and the Subsidiaries taken as a whole.

            3.30 Each of the Company and each Subsidiary is insured against such
losses and risks and in such amounts as are customary in the businesses in which
it is engaged, including but not limited to, insurance covering product
liability and real or personal property owned or leased against theft, damage,
destruction, act of vandalism and all other risks customarily insured against.
All policies of insurance and fidelity or surety bonds insuring the Company, any
Subsidiary or the Company's or any Subsidiary's businesses, assets, employees,
officers and directors are in full force and effect. The Company and each
Subsidiary is in compliance with the terms of such policies and instruments in
all material respects. The Company has no reason to believe that it and the
Subsidiaries will not be able to renew their existing insurance coverage as and
when such coverage expires or to obtain similar coverage from similar insurers
as may be necessary to continue its business at a cost that would not have a
material adverse effect on the Company and the Subsidiaries taken as a whole.
Since January 1, 2004, neither the Company nor any Subsidiary has been denied
any insurance coverage which it has sought or for which it has applied.

            3.31 The Company and each Subsidiary has good and marketable title
in fee simple to all real property and good and marketable title to all personal
property owned by it, in each case free and clear of all liens, encumbrances and
defects except such as are described in the Memorandum or such as do not
materially affect the value of such property and do not materially interfere
with the use made and proposed to be made of such property by the Company or
such Subsidiary. Any real property and buildings held under lease by the Company

            3.32 The Company is subject to the reporting requirements of Section
13 or Section 15(d) of the Exchange Act. Since January 1, 2004, the Company has
timely filed with the SEC all reports required to be filed under the Exchange
Act and the Company is and, as of the time of each Closing will be, current in
its reporting obligations under the Exchange Act. To the Company's knowledge,
the Company has responded to all comments raised by the SEC with respect to the
Company's reports, registration statements and other filings made with the SEC
to the SEC's satisfaction, and no comments which could have an adverse effect on
the Company's consolidated financial condition or results of operations (past or
future) or could require a restatement of previously filed financial statements
remained unresolved with the SEC.

            3.33 There is and there has been no failure on the part of the
Company and the Subsidiaries or, to the Company's knowledge, any of the officers
or directors of the Company or any Subsidiary to comply in all material respects
with the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in
connection therewith.

            3.34 The Company has not distributed and, prior to the exercise or
expiration of all the Options, will not distribute any offering material in
connection with the offering and sale of the Shares other than the Memorandum.

            3.35 Neither the Company nor any of its Affiliates has directly or
indirectly, solicited any offer to buy, sold or offered to sell or otherwise
negotiated in respect of, or will solicit an offer to buy, sell or offer to
sell, or otherwise negotiate in respect of any security which might be
integrated with the sale of the Shares or the Conversion Shares in a manner that
would require the Shares to be registered under the Securities Act. Except as
set forth in the Memorandum, there are no persons with registration rights or
similar rights to have any securities registered by the Company under the
Securities Act. No registration under the Securities Act of the Shares or the
Conversion Shares is required for the sale of the Shares and Conversion Shares
to the Purchasers under this Agreement and the Memorandum, assuming the accuracy
of the Purchasers' representations, warranties and agreements set forth in
Section 4.

            3.36 The Company has established and maintains disclosure controls
and procedures (as such term in defined in Rule 13a-14 and 15d-14 under the
Exchange Act); such disclosure controls and procedures are designed to ensure
that material information relating to the Company, including its consolidated
subsidiaries, is made known to the Company's Chief Executive Officer and its
Chief Financial Officer by others within those entities, and such disclosure
controls and procedures are reasonably effective to perform the functions for
which they were established, subject to the limitation of any such control
system; the Company's auditors and the Audit Committee of the Board of Directors
of the Company have been advised of: (A) any significant deficiencies in the
Company's ability to record, process, summarize, and report financial data; and
(B) any fraud, whether or not material, that involves management or other
employees who have a role in the Company's internal controls; any material
weaknesses in internal controls have been identified for the Company's auditors;
and since the date of the most recent evaluation of such disclosure controls and
procedures, there have been no significant changes in internal controls or in
other factors that could significantly affect internal controls, including any
corrective actions with regard to significant deficiencies and material
weaknesses.

            3.37 The Company acknowledges that it has engaged J Giordano as
placement agent in connection with the Purchase. Neither the Company nor, based
on the representations of J Giordano to the Company, any of its agents has
engaged or will engage in any form of general solicitation or general
advertising (within the meaning of Regulation D) in connection with the
Purchase.

<PAGE>

            3.38 The Company has caused or will cause to be timely filed with
each applicable jurisdiction corresponding to the principal place of business of
each Purchaser (as same has been provided by such Purchasers) all appropriate
documentation required for the registration of the Purchase under applicable
state law or required to secure an exemption from such registration
requirements.

      4. Representations and Warranties of the Purchasers. Each of the
Purchasers, severally and not jointly, hereby represents and warrants to the
Company as of the date hereof as to itself that:

            4.1 Authorization. The Transaction Documents to which such Purchaser
is a signatory constitute valid and legally binding obligations of the
Purchaser, enforceable in accordance with their respective terms, except (a) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium, and
other laws of general application affecting enforcement of creditors' rights
generally, (b) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies, and (c) to the
extent the indemnification provisions contained in the Transaction Documents may
be limited by applicable federal or state laws.

            4.2 Purchase Entirely for Own Account. The Shares acquired by each
Purchaser will be acquired for investment for such Purchaser's own account. Each
Purchaser has full power and authority to enter into this Agreement. 4.3
Disclosure of Information. It acknowledges that it has received and reviewed the
Memorandum. It acknowledges that it has received all the information that it has
requested relating to the Company and the purchase of the Shares and further
represents that it has had an opportunity to ask questions and receive answers
from the Company regarding the terms and conditions of the Purchase. The
foregoing, however, does not limit or modify the representations and warranties
of the Company in Section 3 of this Agreement or the right of the Purchaser to
rely thereon.

            4.4 Restricted Securities. It understands that the Shares and the
Conversion Shares are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Company in a
transaction not involving a public offering, and that under such laws and
applicable regulations such securities may be resold without registration under
the Act, only in certain limited circumstances. In this connection, it
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Act. The transfer
restrictions and other provisions set forth in the Memorandum under the caption
"Notice to Investors," including the legend required thereby, shall apply to the
Shares and Conversion Shares.

            4.5 Accredited Investor. It is an "accredited investor" within the
meaning of Regulation D under the Securities Act.

<PAGE>

            4.6 Release of Funds. It hereby acknowledges and agrees that the
Purchase Price for the Offered Shares being purchased by it hereunder, has been
previously (or prior to the Closing will be) wired by the Purchaser to the
Escrow Agent, and that, upon the Escrow Agent's receipt of executed (by the
Company and such Purchaser) copies of this Agreement, the deliverables set forth
in Section 5 below and a joint disbursement instruction from the Company and J
Giordano covering such Purchase Price funds ("Disbursement Letter"), the Escrow
Agent will wire transfer such Purchase Price funds in accordance with the
Disbursement Letter, provided, however, that if no Disbursement Letter is
received by the Escrow Agent on or prior to October __, 2005 with respect to
such Purchaser's funds, such funds shall be returned without interest to the
Purchaser.

            4.7 Purchasers' Indemnification of the Company. Each Purchaser
hereby indemnifies and holds the Company and its officers, directors and agents
free from any liability they may incur (including the costs of defending any
legal action brought against any of the foregoing parties) as a result of any
breach by such Purchaser of the representations of the Purchaser set forth in
this Section 4.

            4.8 J Giordano Fees. The Purchasers acknowledge that J Giordano is
acting as placement agent in connection with the Purchase and will receive a fee
from the Company for such services equal to 7.0% of the aggregate Purchase Price
paid by the Purchasers for the Shares and will receive a warrant to purchase a
number of shares of Common Stock equal to 7.0% of the number of shares of Common
Stock issuable upon conversion of Shares sold to and paid for by the Purchasers
(in each case, including Option Shares sold to and paid for by the Purchasers).
In addition, if within twelve (12) months following the Closing the Company
sells, directly or indirectly, securities to any Purchaser (other than
securities in connection with a working capital loan or facility or project debt
financing), J Giordano will be entitled to receive the same compensation with
respect to such sale of securities as it will receive in connection with the
Purchase.

      5. Conditions to the Purchasers' Obligations. The obligations of each
Purchaser to purchase and pay for the Offered Shares set forth opposite its name
on the Schedule of Purchasers on the Closing Date are subject to the accuracy of
the representations and warranties of the Company contained in this Agreement or
in any certificate of any officer of the Company delivered pursuant to this
Agreement and to the following further conditions:

            5.1 Officer's Certificate. The Company shall have delivered to J
Giordano, on behalf of the Purchasers, on the Closing Date a certificate, dated

Agreement are true and correct as of the Closing Date and that the Company has
complied with all of the agreements and satisfied all of the conditions on its
part to be performed or satisfied hereunder on or before such Closing Date.

            5.2 Opinion of Counsel. The Company shall have delivered to J

as of the Closing Date, executed by the Secretary of the Company certifying the

transactions contemplated by this Agreement.

            5.6 Registration Rights Agreement. The Company shall have duly
executed the Registration Rights Agreement in the form attached hereto as
EXHIBIT D.

      6. Covenants of the Company. In further consideration of the agreements of
the Purchasers contained in this Agreement, the Company covenants with each
Purchaser as follows:

            6.1 The Company will not solicit any offer to buy or offer or sell
the Shares or the Conversion Shares by means of any form of general solicitation
or general advertising (as those terms are used in Regulation D) or in any
manner involving a public offering within the meaning of Section 4(2) of the
Securities Act.

            6.2 The Company will use its commercially reasonable efforts to
assist J Giordano to apply for quotation of the Preferred Stock on the OTC

            6.3 Neither the Company nor any of its Affiliates will take any
action prohibited by Regulation M under the Exchange Act in connection with the
sale and distribution of the Shares contemplated hereby.

            6.4 Until the date on which the Purchasers shall have sold all the
Conversion Shares held by them and none of the Preferred Stock are outstanding,
the Company shall use its best efforts timely file all reports required to be
filed with the SEC pursuant to the Exchange Act, and the Company shall not
terminate its status as an issuer required to file reports under the Exchange
Act even if the Exchange Act or the rules and regulations thereunder would
otherwise permit such termination.

            6.5 The Company shall take all action necessary to at all times have
authorized, and reserved for the purpose of issuance, the number of shares of
Common Stock issuable as Conversion Shares.

or desirable to carry out the provisions of this Agreement and the other
Transaction Documents.

                                       13
<PAGE>

            6.7 The Company shall maintain such controls and other procedures,
including without limitation those required by Section 302 of the Sarbanes-Oxley
Act and the applicable regulations thereunder, that are reasonably designed to
ensure that information required to be disclosed by the Company in the reports
that it files or submits under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified in the SEC's rules and
forms, including without limitation, controls and procedures reasonably designed
to ensure that information required to be disclosed by the Company in the
reports that it files or submits under the Exchange Act is accumulated and
communicated to the Company's management, including its Chief Executive Officer
and its Principal Financial Officer, or persons performing similar functions, as
appropriate to allow timely decisions regarding required disclosure, to ensure
that material information relating to the Company, including its Subsidiaries,
is made known to them by others within those entities.

            6.8 Notwithstanding anything herein to the contrary, the Company may
not elect to make all or a portion of a dividend payment in shares of Common
Stock or issue shares of Common Stock as payment of the purchase price of a
Change of Control (as defined in the Designation) to the extent such issuance of
Common Stock (when added to the Common Stock issued or issuable upon conversion
of the Preferred Stock) requires stockholder approval under Nasdaq Marketplace
Rule 4350(i) and such stockholder approval had not been obtained. The Company
will use its best efforts to obtain stockholder approval for any such issuance,
if necessary, prior to the time of issuance.

      7. Indemnification.

            7.1 The Company agrees to indemnify and hold harmless each
Purchaser, each person, if any, who controls any Purchaser within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, and
each Affiliate of any Purchaser (individually, the "Indemnified Person" or
collectively the "Indemnified Person") from and against any and all losses,
claims, damages and liabilities (including, without limitation, any legal or
other expenses reasonably incurred in connection with defending or investigating
any such action or claim) (a) caused by any untrue statement or alleged untrue
statement of a material fact contained in the Memorandum (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), (b) caused by any omission or alleged omission to state in the
Memorandum a material fact necessary to make the statements therein in the light
of the circumstances under which they were made not misleading or (c) that arise
out of or are based upon any material breach of any representation, warranty,
agreement obligation or covenant of the Company contained herein.

            7.2 Promptly after receipt of notice of the commencement of any
action in respect of which indemnity may be sought against the Company under
this Section 7, the Indemnified Person will notify the Company in writing of the
commencement thereof, and the Company will, subject the provisions hereinafter
stated, assume the defense of such action (including the employment of counsel
reasonably satisfactory to the Indemnified Person and the payment of expenses in
connection with such defense) insofar as such action relates to an alleged
liability in respect of which indemnity may be sought against the Company under
this Section. After notice from the Company of its election to assume the
defense of such claim or action, and provided it continues to meet its
obligations hereunder, the Company shall no longer be liable to the Indemnified
Person under this Section for any legal or other expenses subsequently incurred
by the Indemnified Person in connection with the defense thereof other than
reasonable costs incurred prior to the Company assuming the defense of such
action; provided, however, that if in the reasonable good faith judgment of the
Indemnified Person or Persons, because of a conflict of interest of the counsel
employed by Company, to be represented by separate counsel, the Indemnified


                                       14
<PAGE>

Person or Persons shall have the right to employ separate counsel to represent
the Indemnified Persons who may be subject to liability arising out of any claim
in respect of which indemnity may be sought by the Indemnified Persons thereof
against the Company, in which event the reasonable fees and expenses of one such
separate counsel to represent all of the Indemnified Persons shall be borne by
the Company.
