2.  BUYERS'  REPRESENTATIONS  AND  WARRANTIES.  Each  Buyer  severally  (and not

     a. Investment  Purpose.  As of the date hereof, the Buyer is purchasing the
Notes and the shares of Common Stock  issuable  upon  conversion of or otherwise
pursuant to the Notes (including,  without limitation, such additional shares of
Common  Stock,  if any, as are issuable (i) on account of interest on the Notes,
(ii) as a result of the events described in Sections 1.3 and 1.4(g) of the Notes
and Section 2(c) of the Registration Rights Agreement or (iii) in payment of the
Standard  Liquidated  Damages Amount (as defined in Section 2(f) below) pursuant
to this Agreement,  such shares of Common Stock being  collectively  referred to
herein as the  "Conversion  Shares")  and the  Warrants and the shares of Common
Stock  issuable upon exercise  thereof (the "Warrant  Shares" and,  collectively
with the Notes,  Warrants and Conversion  Shares,  the "Securities") for its own
account and not with a present  view  towards  the public  sale or  distribution
thereof, except pursuant to sales registered or exempted from registration under
the 1933 Act; provided,  however, that by making the representations herein, the
Buyer  does not agree to hold any of the  Securities  for any  minimum  or other
specific term and reserves the right to dispose of the Securities at any time in
accordance  with or pursuant to a registration  statement or an exemption  under
the 1933 Act.

     b. Accredited  Investor  Status.  The Buyer is an "accredited  investor" as
that term is defined in Rule 501(a) of Regulation D (an "Accredited Investor").

     c. Reliance on Exemptions.  The Buyer  understands  that the Securities are
being  offered  and sold to it in reliance  upon  specific  exemptions  from the
registration requirements of United States federal and state securities laws and
that the  Company is relying  upon the truth and  accuracy  of, and the  Buyer's
compliance with, the representations,  warranties,  agreements,  acknowledgments
and  understandings  of the  Buyer set forth  herein in order to  determine  the
availability  of such exemptions and the eligibility of the Buyer to acquire the
Securities.

     d. Information.  The Buyer and its advisors,  if any, have been, and for so
long as the Notes and Warrants remain outstanding will continue to be, furnished
with all  materials  relating to the  business,  finances and  operations of the
Company and  materials  relating to the offer and sale of the  Securities  which
have been requested by the Buyer or its advisors. The Buyer and its advisors, if
any,  have been,  and for so long as the Notes and Warrants  remain  outstanding
will continue to be,  afforded the  opportunity to ask questions of the Company.
Notwithstanding  the  foregoing,  the Company has not disclosed to the Buyer any
material  nonpublic  information and will not disclose such  information  unless
such information is disclosed to the public prior to or promptly  following such
disclosure  to the Buyer.  Neither such  inquiries  nor any other due  diligence
investigation conducted by Buyer or any of its advisors or representatives shall
modify,  amend or affect Buyer's right to rely on the Company's  representations
and  warranties  contained in Section 3 below.  The Buyer  understands  that its
investment in the Securities  involves a significant  degree of risk. The Buyers
are not aware of any facts that may  constitute a breach of any of the Company's
representations and warranties made herein.

     e. Governmental Review. The Buyer understands that no United States federal
or state agency or any other  government or governmental  agency has passed upon
or made any recommendation or endorsement of the Securities.

     f. Transfer or Re-sale.  The Buyer  understands that (i) except as provided
in the Registration Rights Agreement,  the sale or re-sale of the Securities has
not been and is not being  registered under the 1933 Act or any applicable state
securities  laws,  and the  Securities  may not be  transferred  unless  (a) the
Securities are sold pursuant to an effective  registration  statement  under the
1933 Act,  (b) the Buyer  shall  have  delivered  to the  Company  an opinion of
counsel  reasonably  acceptable  to the Company and its counsel that shall be in
form,  substance  and scope  customary  for  opinions  of counsel in  comparable
transactions  to the effect that the Securities to be sold or transferred may be
sold or  transferred  pursuant to an  exemption  from such  registration,  which
opinion  shall  be  accepted  by the  Company,  (c) the  Securities  are sold or
transferred to an "affiliate" (as defined in Rule 144 promulgated under the 1933
Act (or a  successor  rule)  ("Rule  144")) of the  Buyer who  agrees to sell or
otherwise  transfer the Securities only in accordance with this Section 2(f) and
who is an Accredited Investor, (d) the Securities are sold pursuant to Rule 144,
or (e) the Securities are sold pursuant to Regulation S under the 1933 Act (or a
successor  rule)  ("Regulation  S"),  and the Buyer shall have  delivered to the
Company an  opinion of counsel  reasonably  acceptable  to the  Company  and its
counsel that shall be in form,  substance  and scope  customary  for opinions of
counsel in  corporate  transactions,  which  opinion  shall be  accepted  by the
Company;  (ii) any sale of such  Securities  made in reliance on Rule 144 may be
made only in accordance with the terms of said Rule and further, if said Rule is
not applicable,  any re-sale of such Securities under circumstances in which the
seller  (or the  person  through  whom the sale is made)  may be deemed to be an
underwriter  (as that term is  defined in the 1933 Act) may  require  compliance
with some other exemption under the 1933 Act or the rules and regulations of the
SEC thereunder;  and (iii) neither the Company nor any other person is under any
obligation  to  register  such  Securities  under  the  1933  Act or  any  state
securities  laws or to comply  with the terms and  conditions  of any  exemption
thereunder  (in each  case,  other  than  pursuant  to the  Registration  Rights
Agreement).  Notwithstanding  the foregoing or anything else contained herein to
the contrary,  the Securities may be pledged as collateral in connection  with a
bona fide margin  account or other  lending  arrangement.  In the event that the
Company  does not accept  the  opinion  of  counsel  provided  by the Buyer with
respect  to  the  transfer  of   Securities   pursuant  to  an  exemption   from
registration,  such as Rule 144 or  Regulation S, within three (3) business days
of delivery of the opinion to the  Company,  the Company  shall pay to the Buyer
liquidated  damages of two percent (2%) of the  outstanding  amount of the Notes
per month plus  accrued and unpaid  interest on the Notes,  prorated for partial
months,  in cash or shares at the option of the  Company  ("Standard  Liquidated
Damages  Amount").  If the  Company  elects  to be pay the  Standard  Liquidated
Damages  Amount in shares of Common  Stock,  such shares  shall be issued at the
Conversion Price at the time of payment.  Notwithstanding anything herein to the
contrary,  in the event the Company has to pay the Standards  Liquidated Damages
Amount pursuant to any provision of this Agreement,  the Buyers shall first have
to give the Company advance written notice of such breach and in such event, the
Company  shall have 30 days from the  receipt of such notice to cure such breach
before the Standard  Liquidated  Damages  Amount shall be due and payable to the
Buyers.

     g.  Legends.  The Buyer  understands  that the Notes and the Warrants  and,
until such time as the Conversion Shares and Warrant Shares have been registered
under the 1933 Act as  contemplated  by the  Registration  Rights  Agreement  or
otherwise  may be  sold  pursuant  to  Rule  144 or  Regulation  S  without  any
restriction as to the number of securities as of a particular date that can then
be  immediately  sold,  the  Conversion  Shares  and  Warrant  Shares may bear a
restrictive  legend in  substantially  the following  form (and a  stop-transfer
order may be placed against transfer of the certificates for such Securities):

          "The  securities   represented  by  this  certificate  have  not  been
          registered  under  the  Securities  Act  of  1933,  as  amended.   The
          securities may not be sold,  transferred or assigned in the absence of
          an effective registration statement for the securities under said Act,
          or an opinion of counsel,  in form,  substance and scope customary for
          opinions of counsel in comparable  transactions,  that registration is
          not  required  under said Act or unless  sold  pursuant to Rule 144 or
          Regulation S under said Act."

     The legend set forth above  shall be removed and the Company  shall issue a
certificate  without such legend to the holder of any Security  upon which it is
stamped,  if, unless otherwise required by applicable state securities laws, (a)
such Security is registered for sale under an effective  registration  statement
filed  under  the  1933 Act or  otherwise  may be sold  pursuant  to Rule 144 or
Regulation  S without any  restriction  as to the number of  securities  as of a
particular  date that can then be immediately  sold, or (b) such holder provides
the Company with an opinion of counsel,  in form,  substance and scope customary
for  opinions of counsel in  comparable  transactions,  which  opinion  shall be
reasonably acceptable to the Company's counsel, to the effect that a public sale
or transfer of such  Security  may be made without  registration  under the 1933
Act, which opinion shall be accepted by the Company so that the sale or transfer
is effected or (c) such holder provides the Company with  reasonable  assurances
that such  Security can be sold  pursuant to Rule 144 or Regulation S. The Buyer
agrees to sell all Securities,  including those  represented by a certificate(s)
from which the legend has been removed, in compliance with applicable prospectus
delivery requirements, if any.

     h. Authorization;  Enforcement.  This Agreement and the Registration Rights
Agreement  have been duly and validly  authorized.  This Agreement has been duly
executed and delivered on behalf of the Buyer,  and this Agreement  constitutes,
and  upon  execution  and  delivery  by the  Buyer  of the  Registration  Rights
Agreement,  such agreement will constitute,  valid and binding agreements of the
Buyer enforceable in accordance with their terms.

legality, validity or enforceability of any document executed in connection with
this financing, (ii) a material and adverse effect on the results of operations,
assets, prospects, business or condition (financial or otherwise) of the Company

Agreement  constitutes,  and upon  execution  and delivery by the Company of the
Registration  Rights  Agreement,  the  Notes  and  the  Warrants,  each  of such
instruments  will  constitute,  a legal,  valid and  binding  obligation  of the
Company enforceable against the Company in accordance with its terms.

preemptive rights or any other similar rights of the shareholders of the Company

     d. Issuance of Shares.  The  Conversion  Shares and Warrant Shares are duly
authorized  and reserved  for issuance  and,  upon  conversion  of the Notes and
exercise of the Warrants in  accordance  with their  respective  terms,  will be

claims  and  encumbrances  with  respect to the issue  thereof  and shall not be
subject to preemptive  rights or other  similar  rights of  shareholders  of the
Company and will not impose personal liability upon the holder thereof.

     e. Acknowledgment of Dilution. The Company understands and acknowledges the
potentially  dilutive  effect  to the  Common  Stock  upon the  issuance  of the
Conversion  Shares and Warrant Shares upon conversion of the Note or exercise of
the Warrants.  The Company  further  acknowledges  that its  obligation to issue
Conversion Shares and Warrant Shares upon conversion of the Notes or exercise of
the Warrants in accordance  with this  Agreement,  the Notes and the Warrants is
absolute and unconditional  regardless of the dilutive effect that such issuance
may have on the ownership interests of other shareholders of the Company.

     f. No Conflicts. The execution, delivery and performance of this Agreement,
the Registration Rights Agreement, the Notes and the Warrants by the Company and
the  consummation  by the Company of the  transactions  contemplated  hereby and

issuance of the Conversion Shares and Warrant Shares) will not (i) conflict with
or result in a violation of any provision of the Certificate of Incorporation or
By-laws or (ii) violate or conflict with, or result in a breach of any provision
of, or  constitute  a default (or an event which with notice or lapse of time or
both could become a default) under, or give to others any rights of termination,
amendment,  acceleration or cancellation of, any agreement,  indenture,  patent,
patent license or instrument to which the Company or any of its  Subsidiaries is
a party, or (iii) to the Company's knowledge,  result in a violation of any law,
rule,  regulation,  order,  judgment  or  decree  (including  federal  and state
securities  laws  and   regulations  and  regulations  of  any   self-regulatory
organizations to which the Company or its securities are subject)  applicable to
the Company or any of its  Subsidiaries or by which any property or asset of the
Company  or any of its  Subsidiaries  is  bound  or  affected  (except  for such
conflicts, defaults, terminations, amendments, accelerations,  cancellations and
violations  as would  not,  individually  or in the  aggregate,  have a Material
Adverse Effect). Neither the Company nor any of its Subsidiaries is in violation
of its Certificate of Incorporation,  By-laws or other organizational  documents
and neither the Company nor any of its  Subsidiaries is in default (and no event
has occurred which with notice or lapse of time or both could put the Company or
any of its  Subsidiaries in default)  under,  and neither the Company nor any of
its  Subsidiaries  has taken any action or failed to take any action  that would
give  to  others  any  rights  of   termination,   amendment,   acceleration  or
cancellation of, any agreement,  indenture or instrument to which the Company or
any of its  Subsidiaries  is a party or by which any  property  or assets of the
Company or any of its  Subsidiaries  is bound or  affected,  except for possible
defaults as would not, individually or in the aggregate, have a Material Adverse
Effect.  The  businesses  of the Company and its  Subsidiaries,  if any, are not
being  conducted,  and shall not be conducted so long as a Buyer owns any of the
Securities, in violation of any law, ordinance or regulation of any governmental
entity.  Except as  specifically  contemplated by this Agreement and as required
under the 1933 Act and any applicable  state securities laws, the Company is not
required to obtain any consent, authorization or order of, or make any filing or
registration  with, any court,  governmental  agency,  regulatory  agency,  self
regulatory  organization  or stock  market or any third party in order for it to
execute,  deliver or perform any of its obligations  under this  Agreement,  the
Registration Rights Agreement,  the Notes or the Warrants in accordance with the
terms  hereof  or  thereof  or to issue  and  sell the  Notes  and  Warrants  in
accordance  with the  terms  hereof  and to issue  the  Conversion  Shares  upon
conversion  of the Notes and the Warrant  Shares upon  exercise of the Warrants.
Except as disclosed in Schedule  3(f),  all  consents,  authorizations,  orders,
filings and  registrations  which the Company is required to obtain  pursuant to
the  preceding  sentence  have been obtained or effected on or prior to the date
hereof.  The Company is not in violation of the  quotation  requirements  of the
Over-the-Counter Bulletin Board (the "OTCBB") and does not reasonably anticipate
that the Common  Stock will be removed by the OTCBB in the  foreseeable  future.
The Company and its Subsidiaries are unaware of any facts or circumstances which
might give rise to any of the foregoing.

     g. SEC  Documents;  Financial  Statements.  Except as disclosed in Schedule
3(g),  since  September  30,  2004 the  Company  has timely  filed all  reports,
schedules, forms, statements and other documents required to be filed by it with
the SEC pursuant to the reporting requirements of the Securities Exchange Act of
1934, as amended (the "1934 Act") (all of the foregoing  filed prior to the date
hereof and all exhibits included therein and financial  statements and schedules
thereto and documents  (other than exhibits to such  documents)  incorporated by
reference therein, being hereinafter referred to herein as the "SEC Documents").
As of  their  respective  dates,  the SEC  Documents  complied  in all  material
respects with the  requirements of the 1934 Act and the rules and regulations of
the SEC promulgated thereunder applicable to the SEC Documents,  and none of the
SEC  Documents,  at the time they were filed with the SEC,  contained any untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  under  which they were  made,  not  misleading.  None of the
statements  made in any such SEC  Documents  is,  or has  been,  required  to be
amended or updated under applicable law (except for such statements as have been
amended or updated in subsequent  filings  prior the date  hereof).  As of their
respective  dates,  the financial  statements of the Company included in the SEC
Documents  complied  as  to  form  in  all  material  respects  with  applicable
accounting  requirements and the published rules and regulations of the SEC with
respect thereto. Such financial statements have been prepared in accordance with
United States generally accepted accounting  principles,  consistently  applied,
during the periods  involved  (except (i) as may be otherwise  indicated in such
financial  statements  or the notes  thereto,  or (ii) in the case of  unaudited
interim  statements,  to the extent  they may not  include  footnotes  or may be
condensed or summary statements) and fairly present in all material respects the
consolidated financial position of the Company and its consolidated Subsidiaries
as of the dates thereof and the  consolidated  results of their  operations  and
cash  flows  for the  periods  then  ended  (subject,  in the case of  unaudited
statements,  to normal year-end audit  adjustments).  Except as set forth in the
financial  statements of the Company included in the SEC Documents,  the Company
has no liabilities, contingent or otherwise, other than (i) liabilities incurred
in the ordinary  course of business  subsequent  to September  30, 2004 and (ii)
obligations  under contracts and commitments  incurred in the ordinary course of
business and not required under generally accepted  accounting  principles to be
reflected in such financial statements, which, individually or in the aggregate,
are not material to the financial condition or operating results of the Company.

     h. Absence of Certain Changes.  Except as set forth in Schedule 3(h), since
September 30, 2005,  there has been no material  adverse  change and no material
adverse   development  in  the  assets,   liabilities,   business,   properties,
operations,  financial  condition,  results of  operations  or  prospects of the
Company or any of its Subsidiaries.

     i. Absence of  Litigation.  There is no action,  suit,  claim,  proceeding,
inquiry  or  investigation  before or by any  court,  public  board,  government
agency, self-regulatory organization or body pending or, to the knowledge of the
Company or any of its Subsidiaries,  threatened against or affecting the Company
or any of its Subsidiaries,  or their officers or directors in their capacity as
such,  that could have a  Material  Adverse  Effect.  Schedule  3(i)  contains a
complete list and summary description of any pending or, to the knowledge of the
Company,  threatened  proceeding  against or affecting the Company or any of its
Subsidiaries, without regard to whether it would have a Material Adverse Effect.
The Company and its Subsidiaries are unaware of any facts or circumstances which
might give rise to any of the foregoing.

     j. Patents,  Copyrights, etc. The Company and each of its Subsidiaries owns
or  possesses  the  requisite  licenses  or  rights to use all  patents,  patent
applications,  patent rights, inventions,  know-how, trade secrets,  trademarks,
trademark applications, service marks, service names, trade names and copyrights
("Intellectual  Property") necessary to enable it to conduct its business as now
operated (and,  except as set forth in Schedule 3(j) hereof,  to the best of the
Company's  knowledge,  as presently  contemplated to be operated in the future);
there is no claim or action by any person pertaining to, or proceeding  pending,
or to the Company's  knowledge  threatened,  which  challenges  the right of the
Company or of a Subsidiary with respect to any Intellectual  Property  necessary
to enable it to conduct its business as now operated  (and,  except as set forth
in Schedule 3(j) hereof,  to the best of the Company's  knowledge,  as presently
contemplated  to be  operated  in the  future);  to the  best  of the  Company's
knowledge,  the Company's or its  Subsidiaries'  current and intended  products,
services and  processes do not  infringe on any  Intellectual  Property or other
rights  held  by any  person;  and  the  Company  is  unaware  of any  facts  or
circumstances  which  might give rise to any of the  foregoing.  The Company and
each of its Subsidiaries have taken reasonable  security measures to protect the
secrecy, confidentiality and value of their Intellectual Property.

     k. No Materially Adverse Contracts, Etc. Neither the Company nor any of its
Subsidiaries is subject to any charter, corporate or other legal restriction, or
any judgment,  decree,  order,  rule or regulation  which in the judgment of the
Company's  officers has or is expected in the future to have a Material  Adverse
Effect.  Neither  the  Company  nor any of its  Subsidiaries  is a party  to any
contract or agreement which in the judgment of the Company's  officers has or is
expected to have a Material Adverse Effect.

     l. Tax Status.  Except as set forth on Schedule  3(l), the Company and each
of its Subsidiaries has made or filed all federal,  state and foreign income and
all other tax returns,  reports and declarations required by any jurisdiction to
which it is subject  (unless and only to the extent that the Company and each of
its Subsidiaries has set aside on its books provisions  reasonably  adequate for
the payment of all unpaid and unreported taxes) and has paid all taxes and other
governmental  assessments  and charges  that are  material  in amount,  shown or
determined to be due on such  returns,  reports and  declarations,  except those
being  contested  in good  faith  and  has set  aside  on its  books  provisions
reasonably  adequate for the payment of all taxes for periods  subsequent to the
periods  to which such  returns,  reports or  declarations  apply.  There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction,  and the officers of the Company know of no basis for any such
claim.  The  Company has not  executed a waiver  with  respect to the statute of
limitations  relating to the  assessment or collection of any foreign,  federal,
state or local tax.  Except as set forth on Schedule 3(l), none of the Company's
tax returns is presently being audited by any taxing authority.

     m. Certain  Transactions.  Except as set forth on Schedule  3(m) and except
for  arm's  length  transactions  pursuant  to which the  Company  or any of its
Subsidiaries  makes  payments in the ordinary  course of business  upon terms no
less  favorable  than the Company or any of its  Subsidiaries  could obtain from
third  parties and other than the grant of stock  options  disclosed on Schedule
3(c), none of the officers,  directors, or employees of the Company is presently

by,  providing for rental of real or personal  property to or from, or otherwise
requiring payments to or from any officer,  director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer,  director, or any such employee has a substantial interest or
is an officer, director, trustee or partner.

     n. Disclosure. All information relating to or concerning the Company or any
of its  Subsidiaries  set forth in this  Agreement  and  provided  to the Buyers

transactions  contemplated  hereby is true and correct in all material  respects
and the Company has not omitted to state any material fact necessary in order to
make the statements made herein or therein,  in light of the circumstances under
which they were made, not misleading.  No event or circumstance  has occurred or
exists with  respect to the Company or any of its  Subsidiaries  or its or their
business,  properties,  prospects,  operations or financial  conditions,  which,
under  applicable  law,  rule  or  regulation,  requires  public  disclosure  or
announcement  by the  Company but which has not been so  publicly  announced  or
disclosed  (assuming for this purpose that the Company's reports filed under the
1934 Act are being incorporated into an effective  registration  statement filed
by the Company under the 1933 Act).

     o.  Acknowledgment  Regarding  Buyers' Purchase of Securities.  The Company
acknowledges  and agrees  that the Buyers are acting  solely in the  capacity of
arm's length  purchasers  with respect to this  Agreement  and the  transactions
contemplated hereby. The Company further acknowledges that no Buyer is acting as
a financial  advisor or  fiduciary  of the Company (or in any similar  capacity)
with respect to this Agreement and the transactions  contemplated hereby and any
statement made by any Buyer or any of their respective representatives or agents
in connection with this Agreement and the  transactions  contemplated  hereby is
not advice or a recommendation  and is merely incidental to the Buyers' purchase
of the  Securities.  The  Company  further  represents  to each  Buyer  that the
Company's  decision to enter into this  Agreement  has been based  solely on the
independent evaluation of the Company and its representatives.

     p. No Integrated Offering.  Neither the Company, nor any of its affiliates,
nor any person  acting on its or their behalf,  has directly or indirectly  made
any offers or sales in any security or solicited  any offers to buy any security
under  circumstances  that would require  registration under the 1933 Act of the
issuance of the Securities to the Buyers.  The issuance of the Securities to the
Buyers  will  not be  integrated  with  any  other  issuance  of  the  Company's
securities  (past,  current or future) for purposes of any shareholder  approval
provisions applicable to the Company or its securities.

     q. No Brokers.  Except as set forth in Schedule 3(q), the Company has taken
no  action  which  would  give  rise to any claim by any  person  for  brokerage
commissions,  transaction fees or similar payments relating to this Agreement or
the transactions contemplated hereby.

     r.  Permits;  Compliance.  The Company and each of its  Subsidiaries  is in
possession  of  all  franchises,  grants,  authorizations,   licenses,  permits,
easements, variances, exemptions,  consents, certificates,  approvals and orders
necessary to own,  lease and operate its properties and to carry on its business
as it is now being conducted (collectively, the "Company Permits"), and there is
no action  pending or, to the  knowledge  of the Company,  threatened  regarding
suspension or  cancellation of any of the Company  Permits.  Neither the Company
nor any of its  Subsidiaries is in conflict with, or in default or violation of,
any of  the  Company  Permits,  except  for  any  such  conflicts,  defaults  or
violations  which,  individually  or in the  aggregate,  would not reasonably be
expected to have a Material  Adverse Effect.  Since September 30, 2004,  neither
the Company nor any of its  Subsidiaries  has  received  any  notification  with
respect to possible conflicts, defaults or violations of applicable laws, except
for notices  relating  to possible  conflicts,  defaults  or  violations,  which
conflicts, defaults or violations would not have a Material Adverse Effect.

     s. Environmental Matters.

     (i) Except as set forth in  Schedule  3(s),  there are,  to the best of the
Company's  knowledge,  with respect to the Company or any of its Subsidiaries or
any predecessor of the Company,  no past or present  violations of Environmental
Laws (as defined below), releases of any material into the environment, actions,
activities,   circumstances,   conditions,  events,  incidents,  or  contractual
obligations which may give rise to any common law environmental liability or any
liability  under the  Comprehensive  Environmental  Response,  Compensation  and
Liability  Act of 1980 or similar  federal,  state,  local or  foreign  laws and
neither the Company nor any of its  Subsidiaries  has  received  any notice with
respect to any of the foregoing,  nor is any action pending or, to the Company's
knowledge,  threatened  in  connection  with  any of  the  foregoing.  The  term
"Environmental Laws" means all federal, state, local or foreign laws relating to
pollution or protection of human health or the environment  (including,  without
limitation,  ambient air, surface water, groundwater, land surface or subsurface
strata), including, without limitation, laws relating to emissions,  discharges,
releases or threatened releases of chemicals,  pollutants contaminants, or toxic
or hazardous substances or wastes (collectively, "Hazardous Materials") into the
environment, or otherwise relating to the manufacture, processing, distribution,
use, treatment, storage, disposal, transport or handling of Hazardous Materials,
as well as all  authorizations,  codes,  decrees,  demands  or  demand  letters,
injunctions,  judgments,  licenses,  notices or notice letters, orders, permits,
plans or regulations issued, entered, promulgated or approved thereunder.

     (ii)  Other  than those that are or were  stored,  used or  disposed  of in
compliance with applicable law, no Hazardous Materials are contained on or about
any real property  currently owned,  leased or used by the Company or any of its
Subsidiaries,  and no  Hazardous  Materials  were  released on or about any real
property  previously  owned,  leased  or  used  by  the  Company  or  any of its
Subsidiaries  during the period the  property  was owned,  leased or used by the
Company or any of its Subsidiaries, except in the normal course of the Company's
or any of its Subsidiaries' business.

     (iii) Except as set forth in Schedule  3(s),  to the best of the  Company's
knowledge  there are no underground  storage tanks on or under any real property
owned,  leased or used by the Company or any of its Subsidiaries that are not in
compliance with applicable law.

     t.  Title to  Property.  The  Company  and its  Subsidiaries  have good and
marketable  title in fee  simple to all real  property  and good and  marketable
title to all personal  property  owned by them which is material to the business
of the Company and its  Subsidiaries,  in each case free and clear of all liens,
encumbrances  and defects  except such as are described in Schedule 3(t) or such
as would not have a Material  Adverse  Effect.  Any real property and facilities
held under  lease by the  Company  and its  Subsidiaries  are held by them under
valid,  subsisting and enforceable leases with such exceptions as would not have
a  Material  Adverse  Effect.  u.  Insurance.   The  Company  and  each  of  its
Subsidiaries  are  insured by insurers of  recognized  financial  responsibility
against such losses and risks and in such amounts as  management  of the Company
believes to be prudent and customary in the  businesses in which the Company and
its  Subsidiaries  are engaged.  Neither the Company nor any such Subsidiary has
any reason to believe that it will not be able to renew its  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.

     v. Internal Accounting  Controls.  The Company and each of its Subsidiaries
maintain a system of internal accounting controls sufficient, in the judgment of
the  Company's  board of directors,  to provide  reasonable  assurance  that (i)
transactions  are executed in accordance with  management's  general or specific
authorizations,   (ii)   transactions   are  recorded  as  necessary  to  permit
preparation  of financial  statements  in  conformity  with  generally  accepted
accounting  principles  and to maintain  asset  accountability,  (iii) access to
assets is permitted  only in accordance  with  management's  general or specific
authorization and (iv) the recorded  accountability  for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

     w.  Foreign  Corrupt  Practices.  Neither  the  Company,  nor  any  of  its
Subsidiaries,  nor any director, officer, agent, employee or other person acting
on behalf of the  Company or any  Subsidiary  has,  in the course of his actions
for, or on behalf of, the  Company,  used any  corporate  funds for any unlawful
contribution,  gift,  entertainment  or  other  unlawful  expenses  relating  to
political activity;  made any direct or indirect unlawful payment to any foreign
or domestic government official or employee from corporate funds; violated or is
in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977,
as amended, or made any bribe, rebate,  payoff,  influence payment,  kickback or
other  unlawful  payment  to any  foreign or  domestic  government  official  or
employee.

     x.  Solvency.   The  Company  (after  giving  effect  to  the  transactions
contemplated by this Agreement) is solvent (i.e.,  its assets have a fair market
value in excess of the amount  required to pay its probable  liabilities  on its
existing  debts as they become  absolute and matured) and  currently the Company
has no  information  that would lead it to reasonably  conclude that the Company
would  not,  after  giving  effect  to  the  transaction  contemplated  by  this
Agreement, have the ability to, nor does it intend to take any action that would
impair its  ability to, pay its debts from time to time  incurred in  connection
therewith as such debts mature.

     y. No  Investment  Company.  The Company is not,  and upon the issuance and
sale  of the  Securities  as  contemplated  by  this  Agreement  will  not be an
"investment  company" required to be registered under the Investment Company Act
of  1940  (an  "Investment  Company").  The  Company  is  not  controlled  by an
Investment Company.

     z.  Certain  Registration  Matters.  Assuming  the  accuracy of the Buyers'
representations and warranties set forth in Section 3, no registration under the
Securities Act is required for the offer and sale of the  Conversion  Shares and
Warrant  Shares by the Company to the Buyers  under the  transaction  documents.
Except as specified in Schedule  3(z),  the Company has not granted or agreed to
grant to any Person any rights (including  "piggy-back"  registration rights) to
have any securities of the Company  registered  with the Commission or any other
governmental authority that have not been satisfied.

     aa. Breach of Representations and Warranties by the Company. If the Company
materially  breaches any of the  representations or warranties set forth in this
Section  3, and in  addition  to any  other  remedies  available  to the  Buyers
pursuant  to this  Agreement,  the Company  shall pay to the Buyer the  Standard
Liquidated  Damages Amount in cash or in shares of Common Stock at the option of
the  Company,  until  such  breach is cured.  If the  Company  elects to pay the
Standard Liquidated Damages Amounts in shares of Common Stock, such shares shall
be issued at the Conversion Price at the time of payment.

4. COVENANTS.

     a. Best Efforts. The parties shall use their best efforts to satisfy timely
each of the conditions described in Section 6 and 7 of this Agreement.

     b. Form D; Blue Sky Laws.  The Company agrees to file a Form D with respect
to the Securities as required  under  Regulation D and to provide a copy thereof
to each Buyer  promptly after such filing.  The Company shall,  on or before the
Closing  Date,  take such action as the Company  shall  reasonably  determine is
necessary  to qualify the  Securities  for sale to the Buyers at the  applicable
closing  pursuant to this Agreement  under  applicable  securities or "blue sky"
laws of the states of the United  States  (or to obtain an  exemption  from such
qualification),  and shall provide  evidence of any such action so taken to each
Buyer on or prior to the Closing Date; provided, however, that the Company shall
not be required in connection therewith or as a condition thereto to (a) qualify
to do business in any  jurisdiction  where it would not otherwise be required to
qualify but for this Section 4(b), (b) subject itself to general taxation in any
such jurisdiction,  (c) file a general consent to service of process in any such
jurisdiction,  (d) provide any undertakings that cause the Company undue expense
or burden,  or (e) make any change in its charter or bylaws,  which in each case
the Board of  Directors  of the  Company  determines  to be contrary to the best
interests of the Company and its shareholders.

     c.  Reporting  Status;  Eligibility  to Use Form S-3, SB-2 or Form S-1. The
Company's  Common Stock is  registered  under Section 12(g) of the 1934 Act. The
Company  represents and warrants that it meets the  requirements  for the use of
Form S-3 (or if the  Company is not  eligible  for the use of Form S-3 as of the
Filing Date (as defined in the Registration  Rights Agreement),  the Company may
use the  form of  registration  for  which  it is  eligible  at that  time)  for
registration of the sale by the Buyer of the Registrable  Securities (as defined
in the Registration  Rights  Agreement).  So long as the Buyer beneficially owns
any of the Securities,  the Company shall timely file all reports required to be
filed with the SEC pursuant to the 1934 Act, and the Company shall not terminate
its status as an issuer  required to file reports under the 1934 Act even if the
1934 Act or the rules and regulations  thereunder would permit such termination.
The  Company  further  agrees to file all  reports  required  to be filed by the
Company with the SEC in a timely manner so as to become eligible, and thereafter
to maintain its eligibility,  for the use of Form S-3. The Company shall issue a
press release  describing  the material  terms of the  transaction  contemplated
hereby as soon as  practicable  following  the Closing Date but in no event more
than two (2) business  days of the Closing  Date,  which press  release shall be
subject  to prior  review by the  Buyers.  The  Company  agrees  that such press
release shall not disclose the name of the Buyers unless expressly  consented to
in writing by the Buyers or unless required by applicable law or regulation, and
then only to the extent of such requirement.

     d. Use of Proceeds. The Company shall use the net proceeds from the sale of
the Notes and the  Warrants  in the manner set forth in Schedule  4(d)  attached
hereto and made a part hereof and shall not,  directly or  indirectly,  use such
proceeds  for  (i)  any  loan  to  or  investment  in  any  other   corporation,
partnership, enterprise or other person (except in connection with its currently
existing direct or indirect Subsidiaries);  (ii) the satisfaction of any portion
of the Company's debt (other than payment of trade payables and accrued expenses
in the ordinary course of the Company's  business and consistent with prior past
practices), or (iii) the redemption of any Common Stock.

     e. Future Offerings. Subject to the exceptions described below, the Company
will not,  without the prior written  consent of a  majority-in-interest  of the
Buyers, which consent shall not be unreasonably withheld,  negotiate or contract
with any party to obtain additional  equity financing  (including debt financing
with an equity  component)  that  involves  (A) the issuance of Common Stock for
cash at a  discount  to the  market  price  of the  Common  Stock on the date of
issuance  (taking  into  account the value of any warrants or options to acquire
Common Stock issued in connection  therewith) or (B) the issuance of convertible
securities that are convertible into an indeterminate number of shares of Common
Stock or (C) the issuance of warrants  during the period (the "Lock-up  Period")
beginning on the Closing Date and ending on the later of (i) two hundred seventy
(270) days from the Closing Date and (ii) one hundred eighty (180) days from the
date  the  Registration   Statement  (as  defined  in  the  Registration  Rights
Agreement)  is declared  effective  (plus any days in which sales cannot be made
thereunder). In addition, subject to the exceptions described below, the Company
will not conduct any equity financing  (including debt with an equity component)
("Future  Offerings") during the period beginning on the Closing Date and ending
two (2) years  after the end of the  Lock-up  Period  unless it shall have first
delivered to each Buyer, at least twenty (20) business days prior to the closing
of such Future Offering, written notice describing the proposed Future Offering,
including the terms and conditions thereof and proposed definitive documentation
to be entered into in connection  therewith,  and providing each Buyer an option
during the fifteen (15) day period following delivery of such notice to purchase
its pro rata share (based on the ratio that the  aggregate  principal  amount of
Notes purchased by it hereunder bears to the aggregate principal amount of Notes
purchased  hereunder) of the securities  being offered in the Future Offering on
the same terms as contemplated by such Future Offering (the limitations referred
to in this sentence and the preceding  sentence are collectively  referred to as
the "Capital Raising  Limitations").  In the event the terms and conditions of a
proposed Future Offering are amended in any respect after delivery of the notice
to the Buyers concerning the proposed Future Offering, the Company shall deliver
a new notice to each Buyer  describing  the amended terms and  conditions of the
proposed Future Offering and each Buyer  thereafter  shall have an option during
the fifteen  (15) day period  following  delivery of such new notice to purchase
its pro  rata  share  of the  securities  being  offered  on the  same  terms as
contemplated  by such  proposed  Future  Offering,  as  amended.  The  foregoing
sentence shall apply to successive amendments to the terms and conditions of any
proposed Future Offering. The Capital Raising Limitations shall not apply to any
transaction   involving  (i)  issuances  of  securities  in  a  firm  commitment
underwritten  public offering  (excluding a continuous offering pursuant to Rule
415  under  the  1933  Act,  an  equity  line of  credit  or  similar  financing
arrangement)  resulting  in  net  proceeds  to  the  Company  of  in  excess  of
$1,500,000,  or (ii)  issuances of  securities  as  consideration  for a merger,
consolidation  or  purchase  of  assets,  or in  connection  with any  strategic
partnership  or joint  venture  (the  primary  purpose  of which is not to raise
equity  capital),  or in connection  with the  disposition  or  acquisition of a
business,  product or license by the Company.  The Capital  Raising  Limitations
also shall not apply to the issuance of  securities  upon exercise or conversion
of the Company's options,  warrants or other convertible  securities outstanding
as of the date hereof or to the grant of additional options or warrants,  or the
issuance of additional securities,  under any Company stock option or restricted
stock plan approved by the shareholders of the Company.

     f.  Expenses.  At the  Closing,  the  Company  shall  reimburse  Buyers for
expenses  incurred  by them in  connection  with the  negotiation,  preparation,
execution,  delivery and performance of this Agreement and the other  agreements
to  be  executed  in  connection  herewith  ("Documents"),   including,  without
limitation,  attorneys' and consultants' fees and expenses, transfer agent fees,
fees  for  stock  quotation  services,   fees  relating  to  any  amendments  or
modifications  of the  Documents or any consents or waivers of provisions in the
Documents,  fees for the  preparation  of opinions of counsel,  escrow fees, and
costs of  restructuring  the  transactions  contemplated by the Documents.  When
possible,  the Company must pay these fees directly,  otherwise the Company must
make immediate payment for reimbursement to the Buyers for all fees and expenses
immediately  upon written notice by the Buyer or the submission of an invoice by
the  Buyer.  Notwithstanding  anything  herein to the  contrary,  the  Company's
obligation  to  reimburse  Buyers'  expenses  shall not  exceed  $20,000  in the
aggregate.

     g. Financial Information.  The Company agrees to send the following reports
to  each  Buyer  until  such  Buyer  transfers,  assigns,  or  sells  all of the
Securities:  (i) within  ten (10) days after the filing  with the SEC, a copy of
its Annual  Report on Form 10-KSB its  Quarterly  Reports on Form 10-QSB and any
Current  Reports on Form 8-K; (ii) within one (1) day after  release,  copies of
all press releases issued by the Company or any of its  Subsidiaries;  and (iii)
contemporaneously with the making available or giving to the shareholders of the
Company,  copies of any notices or other information the Company makes available
or gives to such shareholders.

     h.  Authorization  and  Reservation  of  Shares.   Subject  to  Stockholder
Approval,  the Company shall at all times have authorized,  and reserved for the
purpose of issuance,  a  sufficient  number of shares of Common Stock to provide
for the full  conversion or exercise of the  outstanding  Notes and Warrants and
issuance of the  Conversion  Shares and Warrant  Shares in connection  therewith
(based on the Conversion Price of the Notes or Exercise Price of the Warrants in
effect from time to time) and as  otherwise  required by the Notes.  The Company
shall not reduce the number of shares of Common Stock reserved for issuance upon
conversion  of Notes and  exercise of the  Warrants  without the consent of each
Buyer.  The Company  shall at all times  maintain the number of shares of Common
Stock so reserved for issuance at an amount ("Reserved Amount") equal to no less
than  two (2)  times  the  number  that  is then  actually  issuable  upon  full
conversion  of the  Notes  and  upon  exercise  of the  Warrants  (based  on the
Conversion  Price of the Notes or the  Exercise  Price of the Warrants in effect
from  time to  time).  If at any time the  number  of  shares  of  Common  Stock
authorized and reserved for issuance ("Authorized and Reserved Shares") is below
the  Reserved  Amount,  the Company  will  promptly  take all  corporate  action
necessary to authorize  and reserve a  sufficient  number of shares,  including,
without  limitation,  calling a special  meeting of  shareholders  to  authorize
additional shares to meet the Company's  obligations under this Section 4(h), in
the case of an  insufficient  number of authorized  shares,  obtain  shareholder
approval  of an  increase in such  authorized  number of shares,  and voting the
management  shares of the  Company  in favor of an  increase  in the  authorized
shares  of the  Company  to  ensure  that the  number  of  authorized  shares is
sufficient  to meet the  Reserved  Amount.  If the Company  fails to obtain such
shareholder  approval  within  thirty (30) days  following the date on which the
number of Reserved  Amount  exceeds the  Authorized  and  Reserved  Shares,  the
Company shall pay to the Borrower the Standard  Liquidated  Damages  Amount,  in
cash or in shares  of Common  Stock at the  option  of the  Buyer.  If the Buyer
elects to be paid the  Standard  Liquidated  Damages  Amount in shares of Common
Stock,  such  shares  shall be  issued  at the  Conversion  Price at the time of
payment.  In order to ensure that the Company has authorized a sufficient amount
of shares to meet the Reserved Amount at all times,  the Company must deliver to
the Buyer at the end of every month a list  detailing (1) the current  amount of
shares  authorized by the Company and reserved for the Buyer;  and (2) amount of
shares  issuable upon  conversion of the Notes and upon exercise of the Warrants
and as payment of  interest  accrued on the Notes for one year.  If the  Company
fails to provide  such list  within  five (5)  business  days of the end of each
month, the Company shall pay the Standard  Liquidated Damages Amount, in cash or
in  shares  of  Common  Stock at the  option  of the  Buyer,  until  the list is
delivered. If the Buyer elects to be paid the Standard Liquidated Damages Amount
in shares of Common Stock,  such shares shall be issued at the Conversion  Price
at the time of payment.

     i. Listing. The Company shall promptly secure the listing of the Conversion
Shares and Warrant  Shares upon each national  securities  exchange or automated
quotation  system,  if any,  upon which  shares of Common  Stock are then listed
(subject to official  notice of issuance)  and, so long as any Buyer owns any of
the  Securities,  shall  maintain,  so long as any other  shares of Common Stock
shall be so listed,  such listing of all  Conversion  Shares and Warrant  Shares
from time to time  issuable  upon  conversion  of the Notes or  exercise  of the
Warrants.  The  Company  will  obtain  and, so long as any Buyer owns any of the
Securities, maintain the listing and trading of its Common Stock on the OTCBB or
any equivalent replacement exchange, the Nasdaq National Market ("Nasdaq"),  the
Nasdaq  SmallCap  Market  ("Nasdaq  SmallCap"),  the  New  York  Stock  Exchange
("NYSE"),  or the  American  Stock  Exchange  ("AMEX")  and will  comply  in all
respects with the Company's  reporting,  filing and other  obligations under the
bylaws or rules of the National  Association of Securities  Dealers ("NASD") and
such exchanges, as applicable.  The Company shall promptly provide to each Buyer
copies of any  notices it  receives  from the OTCBB and any other  exchanges  or
quotation  systems  on which  the  Common  Stock is then  listed  regarding  the
continued  eligibility  of the Common  Stock for listing on such  exchanges  and
quotation systems.

     j. Corporate  Existence.  So long as a Buyer beneficially owns any Notes or
Warrants,  the Company shall maintain its corporate existence and shall not sell
all or  substantially  all of the  Company's  assets,  except  in the event of a
merger or  consolidation  or sale of all or  substantially  all of the Company's
assets,  where the surviving or successor entity in such transaction (i) assumes
the Company's  obligations  hereunder and under the agreements  and  instruments
entered into in connection  herewith and (ii) is a publicly  traded  corporation
whose Common Stock is listed for trading on the OTCBB, Nasdaq,  Nasdaq SmallCap,
NYSE or AMEX.

     k. No  Integration.  The Company  shall not make any offers or sales of any
security  (other than the  Securities)  under  circumstances  that would require
registration  of the Securities  being offered or sold hereunder  under the 1933
Act or cause the  offering of the  Securities  to be  integrated  with any other
offering  of  securities  by the  Company  for the  purpose  of any  stockholder
approval provision applicable to the Company or its securities.

     l. Restriction on Short Sales. The Buyers agree that, so long as any of the
Notes remain outstanding,  but in no event less than two (2) years from the date
hereof, the Buyers will not enter into or effect any "short sales" (as such term
is  defined  in Rule  3b-3 of the  1934  Act) of the  Common  Stock  or  hedging
transaction  which  establishes a net short  position with respect to the Common
Stock.

     m. Breach of  Covenants.  If the Company  breaches any of the covenants set
forth in this Section 4, and in addition to any other remedies  available to the
Buyers  pursuant  to this  Agreement,  the  Company  shall pay to the Buyers the
Standard  Liquidated Damages Amount, in cash or in shares of Common Stock at the
option of the Company,  until such breach is cured. If the Company elects to pay
the Standard Liquidated Damages Amount in shares, such shares shall be issued at
the Conversion Price at the time of payment.

5. TRANSFER AGENT INSTRUCTIONS. The Company shall issue irrevocable instructions
to its  transfer  agent to issue  certificates,  registered  in the name of each
Buyer or its  nominee,  for the  Conversion  Shares and  Warrant  Shares in such
amounts  as  specified  from  time to time by each  Buyer  to the  Company  upon
conversion of the Notes or exercise of the Warrants in accordance with the terms
thereof (the "Irrevocable Transfer Agent  Instructions").  Prior to registration
of the  Conversion  Shares and Warrant  Shares under the 1933 Act or the date on
which the Conversion  Shares and Warrant Shares may be sold pursuant to Rule 144
without any  restriction as to the number of Securities as of a particular  date
that  can  then be  immediately  sold,  all  such  certificates  shall  bear the
restrictive  legend  specified  in Section 2(g) of this  Agreement.  The Company
warrants  that  no  instruction  other  than  the  Irrevocable   Transfer  Agent
Instructions  referred to in this Section 5, and stop transfer  instructions  to
give  effect to Section  2(f) hereof (in the case of the  Conversion  Shares and
Warrant  Shares,  prior to  registration  of the  Conversion  Shares and Warrant
Shares under the 1933 Act or the date on which the Conversion Shares and Warrant
Shares may be sold pursuant to Rule 144 without any restriction as to the number
of Securities as of a particular date that can then be immediately  sold),  will
be given by the  Company to its  transfer  agent and that the  Securities  shall
otherwise be freely  transferable on the books and records of the Company as and
to the extent provided in this Agreement and the Registration  Rights Agreement.
Nothing in this  Section  shall  affect in any way the Buyer's  obligations  and
agreement  set  forth in  Section  2(g)  hereof to  comply  with all  applicable
prospectus delivery requirements,  if any, upon re-sale of the Securities.  If a
Buyer provides the Company with (i) an opinion of counsel reasonably  acceptable
to the  Company  and its  counsel in form,  substance  and scope  customary  for
opinions  in  comparable  transactions,  to the  effect  that a  public  sale or
transfer of such Securities may be made without  registration under the 1933 Act
and such sale or  transfer is  effected  or (ii) the Buyer  provides  reasonable
assurances  that the  Securities  can be sold  pursuant to Rule 144, the Company
shall permit the transfer, and, in the case of the Conversion Shares and Warrant
Shares,  promptly instruct its transfer agent to issue one or more certificates,
free  from  restrictive  legend,  in  such  name  and in such  denominations  as
specified  by such Buyer.  The Company  acknowledges  that a breach by it of its
obligations  hereunder will cause  irreparable harm to the Buyers,  by vitiating
the intent and purpose of the transactions contemplated hereby. Accordingly, the
Company  acknowledges  that the  remedy at law for a breach  of its  obligations
under this Section 5 may be inadequate  and agrees,  in the event of a breach or
threatened  breach by the Company of the  provisions of this  Section,  that the
Buyers shall be entitled,  in addition to all other  available  remedies,  to an
injunction restraining any breach and requiring immediate transfer,  without the
necessity of showing  economic loss and without any bond or other security being
required.

6. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL. The obligation of the Company
hereunder  to issue and sell the Notes and Warrants to a Buyer at the Closing is
subject  to the  satisfaction,  at or  before  the  Closing  Date of each of the

ruling or injunction shall have been enacted,  entered,  promulgated or endorsed

conditions, provided that these conditions are for such Buyer's sole benefit and
may be waived by such Buyer at any time in its sole discretion:

     a. The Company  shall have executed  this  Agreement  and the  Registration
Rights Agreement, and delivered the same to the Buyer.

complied in all material respects with the covenants,  agreements and conditions
required by this  Agreement to be  performed,  satisfied or complied with by the
Company  at or prior to the  Closing  Date.  The Buyer  shall  have  received  a
certificate  or  certificates,  executed by the chief  executive  officer of the
Company,  dated as of the Closing Date,  to the foregoing  effect and as to such
other matters as may be reasonably  requested by such Buyer  including,  but not
limited  to   certificates   with  respect  to  the  Company's   Certificate  of
Incorporation,  By-laws  and Board of  Directors'  resolutions  relating  to the
transactions contemplated hereby.

     e. No litigation,  statute,  rule,  regulation,  executive  order,  decree,
