     WHEREAS,  the Company  intends to file with the Office of the  Secretary of
State of the State of Wyoming an amendment to its Certificate of  Incorporation,
as amended  ("Certificate") setting forth, among other things, the designations,
rights,  preferences  and privileges  and the  qualifications,  limitations  and
restrictions of the Series A Preferred;

     NOW, THEREFORE, in consideration of the premises contained herein and other
good and valuable consideration,  receipt of which is mutually acknowledged, the
parties hereto agree as follows:

                                    ARTICLE I
             Investment and Purchase of Convertible Preferred Stock

     1.1 Authorization.  Subject to the terms and conditions hereof, the Company
has (i)  authorized  the sale and  issuance  of up to  50,000,000  shares of its
Series A Preferred, having the rights, privileges,  preferences and restrictions
as set forth in the Certificate of the Company


                                       1


attached  hereto as  Exhibit  A, and (ii)  agreed to amend  its  Certificate  to
authorize an aggregate of 50,000,000 shares of Preferred Stock and 1,000,000,000
(One  Billion)  shares  of Common  Stock,  and to  reserve  for  issuance  up to
50,000,000 shares of Preferred Stock and  1,000,000,000  (One Billion) shares of
Common  Stock  required  for  conversion  of the Series A  Preferred  ("Reserved
Shares").  The shares of Common Stock into which the Series A Preferred  will be
convertible are referred to herein as the "Conversion  Stock." The Company shall
obtain  from its  shareholders  prior to  December  31,  2001  approval  for the
authorization of the amended Certificate  described above, except in the case of
any review of or comment on the Company's  proxy statement by the Securities and
Exchange Commission,  in which case the foregoing date shall be extended for the
period of review or comment.

     1.2 Sale of Series A Preferred. Subject to the terms and conditions hereof,
the Company hereby agrees to severally issue and sell and each Purchaser  hereby
agrees to  severally  purchase  from the  Company at the  Closing  the number of
shares of Series A  Preferred  set forth  beside  such  Purchaser's  name in the
Schedule of Purchasers at a price of $1.00 per share (the "Purchase Price").

     1.3 Adjustment of Purchase Price, Issuance of Additional Shares. So long as
any Series A Preferred is issued and outstanding, if the Company shall issue any
shares of Common  Stock,  Preferred  Stock,  any other shares  convertible  into
Common  Stock,  or common stock  equivalents,  including  but not limited to any
options,  warrants or other rights to subscribe for or acquire any Common Stock,
without  consideration or for  consideration  less than the Purchase Price, then
and in each such event the  Company  shall issue  additional  shares of Series A
Preferred to the Purchasers,  pro rata,  within ten (10) days of the issuance of
other securities sold for no consideration or for  consideration  per share less
than the Purchase Price as provided in the Certificate.

     1.4 Issuance of Additional  Series A Preferred.  The Company and Purchasers
acknowledge  that the  Purchase  Price has been  negotiated  based upon  certain
financial  performance  projections  proposed by the Company.  If the  Company's
actual financial  performance,  as determined by Generally  Accepted  Accounting
Principles,  consistently  applied,  in any quarterly or semi-annual period does
not meet or exceed all of the  financial  performance  objectives  described  in
Exhibit B (calculated  prior to any expenses or costs incurred by the Company in
order to comply with the Company's  various  obligations or  undertakings  under
this  Agreement  or other  agreements  related  to this  Agreement)  ("Financial
Performance Objectives"),  the Company shall issue to the Purchasers,  pro rata,
additional  Series A Preferred  equal in number to twenty-five  percent (25%) of
the then  outstanding  Common Stock,  Preferred Stock (including the outstanding
Series A Preferred) and any common stock equivalents,  including but not limited
to any options,  warrants or other rights to subscribe for or acquire any Common
Stock, on an as-if converted and fully diluted basis. Any issuance of additional
Series A Preferred  pursuant to the provisions of this Section 1.4 shall be made
not later than thirty (30) days after the  applicable  quarterly or  semi-annual
period referred to in Exhibit B.


                                       2


     1.5 Promissory Note; Required Payments. A sum equal to the aggregate amount
set  forth  in  Schedule  A  ("Additional  Consideration")  shall be paid by the
Company,  in  accordance  with the  provisions of that certain  promissory  note
attached  hereto as Exhibit C, (the  "Note") in  quarterly  installments  to the
holders of Series A Preferred, commencing March 31, 2002.

     The payments  required  hereinabove  in Section 1.5 shall be  calculated by
multiplying  the excess of the  quarterly  EBITDA for the  Company  (as  defined
hereinafter) less quarterly capital expenditures over $300,000,  by .5 (or 50%).
Such payments shall be paid until the Additional  Consideration  has been repaid
in full. The affirmative consent of New Century shall be required and sufficient
to approve any capital  expenditures  that would exceed the budget  contained in
Exhibit B.

     At the sole option of New Century,  the payments  required  hereinabove  in
Section 1.5 may be  converted  into Series A  Preferred,  in lieu of cash,  at a
price  equal to the Series A Preferred  Purchase  Price (or as such Price may be
adjusted as provided  above in Section  1.3).  If New Century  does not elect to
convert such required  payments into Series A Preferred,  the required  payments
shall be paid in cash in accordance with the foregoing provisions.

If the  Additional  Consideration  is not repaid in full to the Purchasers on or
before July 15,  2003,  the Company  shall  issue to the  Purchasers,  pro rata,
additional Series A Preferred equal in number to fifty percent (50%) of the then
outstanding Common Stock and Preferred Stock (including the outstanding Series A
Preferred),  and any Common Stock equivalents,  including but not limited to any
options, warrants or other rights to subscribe for any Common Stock, on an as-if
converted and fully diluted basis.

     1.6 Board  Representation.  On the Closing Date,  the Board of Directors of
the Company shall be  reconstituted  to a total of five (5)  directors,  and New
Century shall appoint two (2) such directors.  Thereafter,  upon compliance with
applicable law relating to appropriate  information  to or  solicitation  of the
Company's  stockholders,  and in accordance  with the  Certificate,  New Century
shall be entitled to appoint three (3) such directors.  All such directors shall
have all rights, including voting rights and access to information,  as are then
held by the members of the Company's Board of Directors.

     1.7 Employee  Stock Option  Limitations.  As of and after the Closing Date,
the Company may issue or grant stock  options,  warrants or other  securities in
favor of eligible employees or consultants in an aggregate amount not to exceed,
as of  the  Closing  Date,  fifteen  percent  (15%)  of  the  total  issued  and
outstanding  Common  Stock of the  Company,  and the Common Stock into which the
Series A  Preferred  and any other  issued  and  outstanding  securities  of the
Company  are  convertible  (it being  understood  that such  options  may not be
exercised  prior  to  shareholder  approval  of the  amendment  of  the  Company
Certificate  pursuant  to Section  1.1).  The terms and  conditions  of any such
issuances  or grants  shall be fixed by the Board of  Directors,  as the same is
reconstituted on the Closing Date; and the Company's  Registration  Statement on
Form S-8 shall be amended to cover all of the shares that may be issued pursuant
to the option plan, or a new Form S-8 shall be filed covering such shares.


                                       3


     1.8 Special Information Rights. So long as any shares of Series A Preferred
remain outstanding  having a value of Five Hundred Thousand Dollars  ($500,000),

Company is duly  qualified as a foreign  corporation  and in good standing to do
business in all such  jurisdictions  in which the conduct of its business or its

adverse  effect on the  Company's  business as now  conducted  or proposed to be
conducted.  The Company has furnished  each Purchaser or its counsel with copies
of its Certificate  and Bylaws,  as amended.  Said copies are true,  correct and

the transactions  contemplated hereby. This Agreement has been duly executed and
delivered  by an  authorized  officer of the  Company and is a valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, except to the extent that its respective enforceability may be subject to
applicable bankruptcy, insolvency,  reorganization,  moratorium and similar laws
affecting the enforcement of creditors' rights generally or by general equitable
principles.

     3.6 Consents and  Approvals;  No Violations.  The  execution,  delivery and
performance of this Agreement by the Company and the consummation by the Company

properties of the Company under any of the terms,  conditions,  or provisions of
any  note,  bond,  mortgage,   indenture,   permit,  contract,  lease  or  other
instrument, agreement or obligation to which the Company is a party, or by which
it or any of its assets or properties may be bound.

     3.7 Financial  Information.  (a) Since May 15, 2001,  the Company has filed
with the SEC all  required  reports,  schedules,  forms,  statements  and  other
documents  (including exhibits and all other information  incorporated  therein)
required under the Securities Act of 1933, the Securities  Exchange Act of 1934,
and the rules and  regulations  promulgated  under  the  Securities  Act and the
Exchange Act (the "Company SEC Documents").  As of their  respective  dates, the
Company SEC Documents complied in all material respects with the requirements of
the  Securities  Act or the Exchange  Act, as the case may be, and the rules and
regulations  of the SEC  promulgated  thereunder  applicable to such Company SEC
Documents,  and none of the  Company SEC  Documents  at the time they were filed
contained any untrue statement of a material fact or


                                       6


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. The financial statements of the Company included
in the Company SEC Documents  comply as to form, as of their respective dates of
filing  with  the SEC,  in all  material  respects  with  applicable  accounting
requirements  and the published  rules and  regulations  of the SEC with respect
thereto,  and have been prepared in accordance with GAAP (except, in the case of
unaudited  statements,  as  permitted  by Form  10-Q of the  SEC)  applied  on a
consistent  basis during the periods involved (except as may be indicated in the
notes  thereto)  and fairly  present in all material  respects the  consolidated
financial  position of the Company as of the dates thereof and the  consolidated
results of the Company's operations, stockholders' equity and cash flows for the
periods  then ended  (subject,  in the case of unaudited  statements,  to normal
recurring  year-end  audit  adjustments)  and  are  consistent  in all  material
respects  with the books and records of the Company.  Since May 15, 2001,  there
has  been  no  change  in any  of  the  significant  accounting  (including  tax
accounting)  policies,  practices  or  procedures  of the  Company.  Except  for
liabilities  or obligations  that are accrued or reserved  against the Company's
financial  statements included in the Company SEC Documents,  the Company has no
liabilities or obligations (whether absolute,  accrued, contingent or otherwise,
and whether due or to become due) that would be required by GAAP to be reflected
on a consolidated balance sheet, or the notes thereto.

          (b)  Except  for  liabilities  or  obligations  (i)  reflected  in the
     financial  statements or in the notes  thereto  included in the Company SEC
     Documents, (ii) incurred in the ordinary course of business consistent with
     past  practice  since  the  date  of  the  most  recent  audited  financial
     statements  of the Company  contained in the Company SEC Documents or (iii)
     incurred in connection with this Agreement or the transactions contemplated
     hereby,  the Company has no liabilities or obligations  (whether  absolute,
     accrued,  contingent or otherwise) of any nature which,  individually or in
     the  aggregate,  would  have  material  adverse  effect  on  the  Company's
     financial condition of operations.

     3.8 Changes.  Since May 15, 2001,  (i) the Company has not entered into any
transaction  which was not in the ordinary  course of  business,  (ii) there has
been no  material  adverse  change,  individually  or in the  aggregate,  in the
condition (financial or otherwise), business, property, assets or liabilities of
the Company other than changes in the ordinary  course of business,  (iii) there
has been no damage to,  destruction of or loss of physical  property  materially
and adversely  affecting  the business or  operations  of the Company,  (iv) the
Company has not  declared or paid any dividend or made any  distribution  on its
stock or redeemed,  purchased or  otherwise  acquired any of its stock,  (v) the
Company has not increased the  compensation of any of its officers,  or the rate
of pay of its  employees  as a group,  except  as part of  regular  compensation
increases in the ordinary course of business, (vi) there has been no resignation
or termination  of employment of any key officer,  consultant or employee of the
Company  and  the  Company  does  not  know  of  the  impending  resignation  or
termination  of  employment  of any key officer,  consultant  or employee of the
Company  that if  consummated  would  have a  materially  adverse  effect on its
business,  (vii) there has not been any change other than in the ordinary course
of business in the  contingent  obligations  of the Company by way of


                                       7


guaranty,  endorsement,  indemnity, warranty or otherwise, (viii) there have not
been  any  loans  made  by the  Company  to any of its  employees,  officers  or
directors  other than in the  ordinary  course of business  and (ix) to the best
knowledge of the Company, there has not been any other event or condition of any
character  pertaining to and  materially  and adversely  affecting the assets or
business of the Company.

     3.9 Absence of  Undisclosed  Liabilities.  On the Closing  Date,  except as
disclosed  in the Company SEC  Documents  (i) the  Company had no  liability  in
excess of $25,000, in the aggregate, of any nature (matured or unmatured,  fixed
or contingent)  which was not provided for or disclosed,  and (ii) all liability
reserves  established  by the Company were  adequate in all  material  respects.
There were no loss contingencies (as such term is used in Statement of Financial
Accounting  Standards No. 5 issued by the Financial  Accounting Standards Board)
which were not adequately provided for in all material respects.

     3.10 Title to Properties and Assets;  Liens,  etc. The Company has good and
marketable  title to its  properties  and  assets  and has good title to all its
leasehold interests,  in each case subject to no mortgage,  pledge, lien, lease,
encumbrance  or charge,  other  than the lien of  current  taxes not yet due and
payable and liens and pledges  pertaining to debt  instruments  presented on the
Balance Sheet.

     3.11 Legal Compliance;  Compliance with Instruments.  The Company is not in
violation of any provision of its Certificate or Bylaws,  as amended,  or of any
loan agreement or other agreement to which it is a party,  other than violations
which singly or in the aggregate will not have a material  adverse effect on the
business,  condition (financial or otherwise),  assets, properties or operations
or prospects  of the Company or any of its  subsidiaries  taken as a whole.  The
Company  is not,  nor is it  alleged  to be,  in  violation  or  default  of any
applicable  law,  statute,  order,  rule or regulation  promulgated  thereunder,
relating to or affecting the operation,  conduct or ownership of the property or
business of the  Company,  which  violation  or default or alleged  violation or
default would,  individually or in the aggregate, have a material adverse effect
on the business of the Company or any of its properties or assets.  There are no
adverse orders, judgments,  writs, injunctions,  decrees or demands of any court
or administrative body, domestic or foreign, or of any other governmental agency
or instrumentality,  domestic or foreign, outstanding against the Company or any
of its subsidiaries.

     3.12  Intellectual  Property Rights.  To the best knowledge of the Company,
the Company owns or has the right to use all  Intellectual  Property  Rights (as
such  term is  defined  in  Section  7.16)  that are  required  to carry out the
Company's  business plan. Except with respect to regulatory  approvals which may
in the future be required with respect to products or services  offered or to be
offered  by  the   Company,   the  Company  has  all   governmental   approvals,
authorizations,  consents  and  permits  necessary  or  required  to conduct its
business as presently conducted or as presently proposed to be conducted. To the
best knowledge of the Company,  no product or service  presently  proposed to be
manufactured,  marketed  or sold by the  Company  will  violate  any  license or
infringe any legally valid  Intellectual  Property  Right or the assumed name of
another.  There are no outstanding  options,  licenses or agreements of any kind
relating to such


                                       8


Intellectual  Property Rights.  The Company has not received any  communications
alleging  that the  Company  has  violated  or, by  conducting  its  business as
proposed,  would violate any of the  Intellectual  Property  Rights of any other
person  or  entity.  The  Company  is not  aware  that any of its  employees  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 their duties to
the Company or that would conflict with the Company's business as proposed to be
conducted.  Neither  the  execution  nor  delivery  of this  Agreement,  nor the
carrying  on of the  Company's  business as  proposed,  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  employee  is now  obligated.  The Company  does not
believe it is or will be necessary to utilize any  inventions,  trade secrets or
proprietary  information of any of its employees made prior to their  employment
by the Company, except for inventions,  trade secrets or proprietary information
that have been assigned or licensed to the Company.

     3.13 Litigation.  There is no action, suit, proceeding at law or in equity,
arbitration  or  administrative  or  other  proceeding  by  or  before  (or  any
investigation by) any governmental or other instrumentality or agency,  pending,
or, to the best knowledge of the Company,  threatened,  against or affecting the
properties or rights of the Company,  and the Company does not know of any valid
basis for any such action, proceeding or investigation. There are no such suits,
actions, claims,  proceedings or investigations pending or to the best knowledge
of the Company,  threatened,  seeking to prevent or challenge  the  transactions
contemplated by this Agreement.

     3.14 Registration  Rights.  Except as set forth in the Registration  Rights
Agreement attached hereto as Exhibit E, the Company is not under any contractual
obligation to register any of its presently outstanding securities or any of its
securities which may hereafter be issued.

     3.15 Governmental Consents;  etc. No consent,  approval or authorization of
(or designation,  declaration or filing with) any governmental  authority on the
part of the Company is  required  in  connection  with the valid  execution  and
delivery  of this  Agreement,  or the offer,  sale or  issuance  of the Series A
Preferred and the Conversion Stock, or the consummation of any other transaction
contemplated  hereby,  except  qualification  (or taking  such  action as may be
necessary to secure an exemption from qualification,  if available) of the offer
and sale of the Series A Preferred  and the  Conversion  Stock under  applicable
federal  and  state  securities  laws,  which  filings  and  qualifications,  if
required, will be accomplished in a timely manner.

     3.16 Offering.  Subject to the accuracy of the Purchasers'  representations
in Article IV hereof,  the offer, sale and issuance of the Series A Preferred to
be issued in conformity with the terms of this Agreement and the issuance of the
Conversion   Stock  upon  conversion  of  the  Series  A  Preferred   constitute
transactions  exempt  from the  registration  requirements  of  Section 5 of the
Securities Act of 1933, as amended ("Securities Act").


                                       9


     3.17  Brokers or Finders;  Other  Offers.  The Company has not incurred and
will not incur,  directly or indirectly,  as a result of any action taken by the
Company,  any liability for brokerage or finders' fees or agents' commissions or
similar charges in connection with this Agreement.

     3.18 Tax Matters. The Company (i) has timely filed all required tax returns
with all appropriate federal, state, county and local governmental agencies (and
all such returns fairly reflect the Company's operations for tax purposes), (ii)
has timely paid all taxes owed by it for which it is obligated to withhold  from
amounts owing to any employee  (including  without  limitation  social  security
taxes),  creditor  or third party  (other  than taxes the  validity of which are
being  contested  in good faith by  appropriate  proceedings)  and (iii) has not
waived  any  statute  of  limitations  with  respect  to taxes or  agreed to any
extension of time with respect to a tax assessment or deficiency. The assessment
of any  additional  taxes for periods for which  returns  have been filed is not
expected  to exceed  the  recorded  liability  therefor,  and to the best of the
Company's  knowledge,  there  are no  material  unresolved  questions  or claims
concerning the Company's tax liability.  The Company's tax returns have not been
reviewed or audited by any federal,  state,  local or county  taxing  authority.
There is no pending  dispute with any taxing  authority  relating to any of said
returns  which,  if  determined  adversely to the  Company,  would result in the
assertion by any taxing authority of any valid deficiency in any material amount
for taxes.

     3.19  Environmental  and  Safety  Regulations.  The  Company  knows  of  no
violation  or  violations  by  the  Company,  its  employees  or  agents  of any
environmental  or safety statute,  law or regulation that in the aggregate would
have a  material  adverse  effect  on the  business,  properties,  prospects  or
financial  condition of the Company,  and to the best of the Company's knowledge
no  material  expenditures  are or will be  required in order to comply with any
such  existing  statute,  law  or  regulation.  No  action,  proceeding,  permit
revocation,  writ,  injunction or claim is pending or, to the best  knowledge of
the Company threatened,  concerning the Company's  facilities and the Company is
not aware of any fact or  circumstance  which  could  involve the Company in any
environmental litigation or impose any material environmental liability upon the
Company.

     3.20 Disclosure. This Agreement and the Exhibits and Schedules hereto, when
taken as a whole, do not contain any untrue statement of a material fact or omit
to state a material  fact  necessary in order to make the  statements  contained
herein and therein not misleading in light of the circumstances under which they
were made.

                                   ARTICLE IV
                Representations and Warranties of the Purchasers

     Each Purchaser hereby severally represents and warrants to the Company with
respect to the purchase of shares of Series A Preferred as follows:


                                       10


     4.1  Authorization.  The execution,  delivery and performance by it of this
Agreement has been duly authorized by all requisite action by it and constitutes
a valid and binding obligation, enforceable in accordance with its terms, except
(i) as limited by applicable bankruptcy, insolvency, reorganization,  moratorium
or other laws of general  application  affecting the  enforcement  of creditor's
rights,  and (ii) general principles of equity that restrict the availability of
equitable remedies.

     4.2 Experience.  It has substantial  experience in evaluating and investing
in private  placement  transactions  of securities  in companies  similar to the
Company  so that it is  capable  of  evaluating  the  merits  and  risks  of its
investment and has the capacity to protect its own interests.

     4.3  Investment.  It is acquiring the Series A Preferred and the Conversion
Stock for investment for its own account, not as a nominee or agent and not with
the view to or for  resale  in  connection  with any  distribution  thereof.  It
understands  that the Series A Preferred and the Conversion Stock have not been,
and will not be  registered  under the  Securities  Act by  reason  of  specific
exemption from the registration  provisions of the Securities Act and applicable
state  securities  laws,  the  availability  of which depends upon,  among other
things,  the bona fide nature of the  investment  intent and the accuracy of the
Purchasers' representations as expressed herein.

     4.4  Restrictive  Legend/Rule  144.  Each  certificate  for  the  Series  A
Preferred and any shares of capital stock received in respect  thereof,  whether
by reason of a stock split or share  reclassification  thereof, a stock dividend
thereon or otherwise  and each  certificate  for any such  securities  issued to
subsequent transferees of any such certificate shall (unless otherwise permitted
by the  provisions  of other  written  agreement  executed  by the  Company  and
Purchasers) be stamped or otherwise  imprinted with legends in substantially the
following form:

                  [remainder of page left blank intentionally]


                                       11


          THE  SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE BEEN
          ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN  REGISTERED  UNDER
          THE  SECURITIES  ACT OF 1933, AS AMENDED.  UNLESS  OTHERWISE
          PERMISSIBLE   UNDER  THE  SECURITIES  ACT  OF  1933,   THESE
          SECURITIES  MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
          SUCH REGISTRATION OR AN EXEMPTION  THEREFROM UNDER SAID ACT.
          ADDITIONALLY, THE TRANSFER OF THESE SECURITIES IS SUBJECT TO
          THE  CONDITIONS   SPECIFIED  IN  SERIES  A  PREFERRED  STOCK
          PURCHASE  AGREEMENT  DATED AUGUST 6, 2001,  AMONG THE ISSUER
          AND CERTAIN OTHER  SIGNATORIES  THERETO,  AND NO TRANSFER OF
          THESE  SECURITIES  SHALL BE VALID OR  EFFECTIVE  UNTIL  SUCH
          CONDITIONS  HAVE BEEN  FULFILLED.  UPON THE  FULFILLMENT  OF
          CERTAIN OF SUCH CONDITIONS, THE ISSUER HAS AGREED TO DELIVER
          TO THE HOLDER  HEREOF A NEW  CERTIFICATE,  NOT BEARING  THIS
          LEGEND, FOR THE SECURITIES  REPRESENTED HEREBY REGISTERED IN
          THE NAME OF THE HOLDER HEREOF.  COPIES OF SUCH AGREEMENT MAY
          BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
          OF  RECORD  OF  THIS  CERTIFICATE  TO THE  SECRETARY  OF THE
          ISSUER.

The Purchaser  understands that the exemption from registration afforded by Rule
144 (the provisions of which are known to the Purchasers)  promulgated under the
Securities  Act depends on the  satisfaction  of various  conditions  and is not
currently available to the Purchaser, and that, if and when applicable, Rule 144
may afford the basis for sales by a Purchaser only in limited amounts.

     4.5 Access to Information.  The Purchaser has had an opportunity to discuss
the  Company's  business,  management  and  financial  affairs  with  directors,
officers and management of the Company,  to review the Company's  operations and
facilities  and has  received  all  information  as such  Purchaser  has  deemed
necessary or appropriate as a prudent and knowledgeable  Purchaser in evaluating
its purchase of the Securities being purchased by the Purchaser.

     4.6 No  Broker.  The  Purchaser  has not  employed  any broker or finder in
connection with the  transactions  contemplated  by this Agreement.  Neither the
