     4.     Representations  and  Warranties of the Company.  As of the Closing,
            ------------------------------------------------
the  Company  represents  and  warrants  as  follows:

          (a)     The  Company is a corporation duly organized, validly existing
and  in  good  standing  under  the  laws  of the State of Delaware, and has the
requisite  corporate  power  and authority to execute and deliver this Agreement
and  to  perform  its  obligations  hereunder.

          (b)     The execution, delivery and performance of this Agreement, and
the  sale  and  delivery  of the Purchaser Securities to the Purchaser have been
duly  authorized  by  all  necessary corporate action on the part of the Company
and, subject to the qualification that certain consents are required of existing
secured  lenders  of  the  Company  before  the  Company  can grant the security
interest  contemplated  by  Section  2.3  of  the Note included in the Purchaser
Securities,  which  consents  the  Company believes, but can provide no absolute
assurance,  that it will be able to obtain, do not violate any material covenant
contained  in  any  agreement  to  which  the  Company  is  a  party.

          (c)     The  Warrant  Shares  covered  by the Warrants included in the
Purchaser  Securities, when issued upon exercise of such Warrants and receipt by
the  Company  of  full  payment therefor, will be duly and validly issued, fully
paid  and  nonassessable.

          (d)     Subject  to  the  truth  and  accuracy  of  the  Purchaser's
representations  set  forth  in  Section  5  of this Agreement and the truth and
accuracy  of  the  representations  of  PMG  contemplated  by  Section 7 of this
Agreement,  the  offer,  sale  and  issuance  of  the  Purchaser  Securities  as

Interest  in  Assets  (as  such  terms  are  defined  in Section 2.3 of the Note
included  in  the  Purchaser  Securities)  and/or  for working capital purposes.

          (f)     All  reports,  registrations,  documents, statements and other
filings  required  to  be  made  by the Company with the Securities and Exchange
Commission  (the  "Commission")  within  the past twelve months have been timely
filed,  and  none  of such materials contains any untrue statement of a material
fact  or  omits  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.

          5.     Representations and Warranties of the Purchaser.  The Purchaser

represents  and  warrants  as  follows:


                                 Page 49 of 106

          (a)   General:
                -------

               (i)     The  Purchaser  has all requisite authority to enter into
this Agreement and to perform all of the obligations required to be performed by
the  Purchaser  hereunder.

               (ii)     Neither  the  Company nor any person acting on behalf of
the  Company  has  offered  or sold the Purchaser Securities to the Purchaser by
means of any form of general solicitation or general advertising.  The Purchaser
has  not  received,  paid  or  given,  directly or indirectly, any commission or
remuneration  for or on account of any sale, or the solicitation of any sale, of
the  Purchaser  Securities.

          (b)   Information  Concerning  the  Company:
                -------------------------------------

               (i)     The  Purchaser  has  had  full  access  to  all  reports,
registrations,  documents,  statements  and other filings heretofore made by the
Company  with  the  Commission under the Securities Act, the Securities Exchange
Act  of  1934,  as  amended,  and  the  rules and regulations promulgated by the
Commission  thereunder.  The  Purchaser is thoroughly familiar with the business
and  financial  condition,  properties, operations and prospects of the Company.

               (ii)      The  Purchaser  has  been  given  full  access  to  all
information  requested  by  the  Purchaser concerning the business and financial
condition,  properties,  operations and prospects of the Company.  The Purchaser
and  his  advisors  (if any) have had an opportunity to ask questions of, and to
receive  information  from,  the  Company  and  persons  acting  on  its  behalf
concerning  the  terms  and  conditions  of  the  Purchaser's  investment in the
Purchaser  Securities,  and  to  obtain  any additional information necessary to
verify  the accuracy of the information and data received by the Purchaser.  The
Purchaser  is  satisfied  that  there  is no material information concerning the
business  and  financial  condition,  properties, operations or prospects of the
Company  of  which  Purchaser  is  unaware.

               (iii)     The  Purchaser  has made, either alone or together with
his  advisors  (if  any),  such  independent  investigation  of the Company, its
management, and related matters as the Purchaser deems to be, or the Purchaser's
advisors  (if any) have advised to be, necessary or advisable in connection with
the  Purchaser's  investment  in the Purchaser Securities; and the Purchaser and
his advisors (if any) have received all information and data which the Purchaser
and  his advisors (if any) believe to be necessary in order to reach an informed
decision  as  to  the  advisability  of  investing  in the Purchaser Securities.

               (iv)     The  Purchaser  understands  that  all  the  Purchaser's
representations  and  warranties  contained  in this Agreement will be deemed to
have  been  reaffirmed  and  confirmed  as  of  the  Closing.


                                 Page 50 of 106

               (v)     The  Purchaser  understands  that  the  purchase  of  the
Purchaser  Securities  involves  various  risks,  including  the risk that it is
unlikely  that  any market will exist for any resale of the Note or the Warrants
included in the Purchaser Securities and that resale of such Note, such Warrants
and  the  Warrant  Shares  issuable  upon  exercise  of  such  Warrants  will be
restricted  as  herein  provided.

          (c)     Status  of  Purchaser:
                  ---------------------

               (i)  The Purchaser is an "accredited investor" within the meaning
of  Rule  501 of Regulation D promulgated by the Commission under the Securities
Act;  and  the  Purchaser either alone or with the Purchaser's advisors (if any)
has  such  knowledge, skill and experience in business, financial and investment
matters  as to be capable of evaluating the merits and risks of an investment in
the  Purchaser  Securities.  To  the  extent  that  the  Purchaser has deemed it
appropriate to do so, the Purchaser has retained at the Purchaser's own expense,
and  relied  upon, appropriate professional advice regarding the investment, tax
and  legal  merits  and consequences of this Agreement and his investment in the
Purchaser  Securities.

          (d)     Restrictions  on  Transfer  or  Sale:
                  ------------------------------------

               (i)     The  Purchaser  is acquiring the Purchaser Securities and
any  Warrant  Shares  purchased  upon  exercise  of the Warrants included in the
Purchaser  Securities  solely  for his own account, for investment purposes, and
not  with  a  view to, or for resale in connection with, any distribution of the
Purchaser  Securities  or  such  Warrant Shares.  The Purchaser understands that
neither  such  Purchaser Securities nor such Warrant Shares have been registered
or  qualified  under  the  Securities  Act,  or the securities laws of any state
(collectively,  the  "State  Securities Laws"), by reason of specific exemptions
under  the provisions thereof which depend in part upon the investment intent of
the Purchaser and upon the accuracy of all of the representations and warranties
made  by  the  Purchaser  in this Agreement.  The Purchaser understands that the
Company  is  relying  upon  the  representations and agreements of the Purchaser
contained  in  this  Agreement  for  the  purpose  of  determining  whether this
transaction  meets  the  requirements  for  such  exemptions.

               (ii)     The  Purchaser understands that the Purchaser Securities
and  any  Warrant Shares acquired upon exercise of the Warrants included therein
are  "restricted  securities"  under applicable federal securities laws and that
the  Securities  Act  and the rules and regulations of the Commission provide in
substance  that the Purchaser may dispose of such securities or any of them only
pursuant  to  an  effective  registration statement under the Securities Act and
applicable State Securities Laws or an exemption therefrom, and understands that
the Company has no obligations or intentions to register or qualify  any of such
securities  thereunder,  or  to  take  any  other  action  so as to permit sales
pursuant  to  the Securities Act and applicable State Securities Laws, except as
set  forth  in  the  Registration  Rights Agreement.  Accordingly, the Purchaser
understands  that  under  the  Commission's rules and regulations and applicable
State  Securities Laws, unless disposed of pursuant to an effective registration


                                 Page 51 of 106

statement  under  the  Securities  Act  and  an  effective  registration  or
qualification  under applicable State Securities Laws, the Purchaser may dispose
of the Purchaser Securities and any Warrant Shares acquired upon exercise of the
Warrants  included  therein  only  in accordance with the provisions of Rule 144
promulgated by the Commission under the Securities Act, to the extent available,
or  in  "private placements" which are exempt from registration or qualification
under  the  Securities  Act and applicable State Securities Laws, in which event
the  transferee  will  acquire  "restricted  securities"  subject  to  the  same
limitations  as in the hands of the Purchaser.  As a consequence, absent such an
effective  registration or qualification under the Securities Act and applicable
State Securities Laws, the Purchaser understands that it may be required to bear
the  economic  risks  of  the  investment  in the Purchaser Securities (and such
Warrant  Shares)  for  an  indefinite  period  of  time.

               (iii)     The  Purchaser  agrees  that (a) the Purchaser will not
sell, transfer, encumber or otherwise dispose of the Purchaser Securities or any
Warrant  Shares  acquired  upon exercise of the Warrants included therein or any
interest  in  any  thereof or therein, or make any offer or attempt to do any of
the  foregoing,  except  pursuant to an effective registration and qualification
under  the  Securities  Act  and  applicable  State  Securities  Laws  or  in  a
transaction  which, in the opinion of counsel satisfactory to the Company (which
requirement may be waived by the Company upon advice of counsel), is exempt from
the  registration  and  qualification  requirements  of  the  Securities Act and
applicable  State  Securities  Laws;  (b)  the  Purchaser  Securities  and  any
certificate(s)  representing Warrant Shares issued upon exercise of the Warrants
included  therein  will  bear  a  legend  making  reference  to  the  foregoing
restrictions;  and  (c) the Company and any transfer agent for the Company shall
not  be  required  to  give  effect  to  any  purported  transfer of any of such
securities  except  upon  compliance  with  the  foregoing  restrictions.

               (iv)     The  registration rights granted to the Purchaser in the
Registration  Rights  Agreement are not assignable or otherwise transferrable by
the  Purchaser.  In  no  event shall any sale, assignment, pledge or transfer of
the  Warrants  included  in  the Purchaser Securities or Warrant Shares issuable
upon  exercise of the Warrants included therein by the Purchaser to a transferee
give  rise  to  rights  of  any  such  transferee  under the Registration Rights
Agreement.

          (e)     Documents.  The  Purchaser has carefully read, and understands
                  ---------
and agrees to be bound by, all of the provisions of this Agreement, the Note and
the  Warrants  included  in the Purchaser Securities and the Registration Rights
Agreement.

     6.     Conditions  to  Obligations  of  Purchaser  and  the  Company.  The
            -------------------------------------------------------------
obligations  of  the  Purchaser to purchase and pay for the Purchaser Securities
and  of the Company to sell and deliver such Purchaser Securities are subject to
the  satisfaction  at  or  prior  to  the  Closing  of  the following conditions
precedent:

          (a)     The representations and warranties of the Company contained in
Section  4  hereof  and  of the Purchaser contained in Section 5 hereof shall be
true  and  correct  on  and  as  of
the  Closing  in all respects with the same effect as though representations and
warranties  had  been  made  on  and  as  of  the  Closing.


                                 Page 52 of 106

          (b)     The  Company  and  the  Purchaser shall each have executed and
delivered the Registration Rights Agreement, and the Company shall have executed
and  delivered  to  the  Purchaser  the  Note  and  the Warrants included in the
Purchaser  Securities.

          (c)     The  Company  and  the  Purchaser shall each have executed and
delivered  this Agreement, and the Purchaser shall have delivered to the Company
(as  contemplated  hereby) the full Purchase Price for the Purchaser Securities.

     7.     Fee.     In  connection with the purchase and sale of the Securities
            ---
(including  the  Purchaser  Securities),  PMG,  in  consideration  of  acting as
placement  agent  for the Company in connection with the Offering and of certain
other services (the "Other Services") rendered or to be by PMG to the Company in
connection  therewith,  shall  receive a fee from the Company equal to 7% of the
Purchase  Price  of  all  of  the Notes sold in the Offering, and be entitled to
reimbursement  by  the  Company  for  PMG's  out-of-pocket  expenses  (including
reasonable  attorneys  fees) associated with the Offering and the Other Services
in  an  amount  not  to  exceed  a  total of $15,000.  In addition, PMG shall be
entitled  to  receive warrants to purchase shares of Common Stock of the Company
at  the  rate  of  warrants for 25,000 shares of Common Stock of the Company for
every  $1,000,000 principal amount of Notes issued by the Company through PMG in
the  Offering.  Such warrants will be exercisable until December 15, 2002, at an
exercise  price  of  $4.00  per share, and contain other rights and restrictions
largely  comparable  to  those contained in the Warrants; and the warrant shares
covered  by  such  warrants  will  have  registration rights comparable to those
provided  for in the Registration Rights Agreement.  The Company's obligation to
pay  the  foregoing  to PMG shall be contingent upon the Company's prior receipt
from  PMG of a representation letter, reasonably satisfactory to the Company, in
which,  among other things, PMG (i) provides representations comparable to those
set  forth  in  Section  5 hereof, (ii) represents that the Offering, and all of
PMG's  activities  in connection therewith, and the consideration to be received
by  PMG  as  contemplated  by  this  Section  7,  in  each  case comply with all
applicable  federal  and  state  securities  laws  and  National  Association of
Securities  Dealers,  Inc.  rules  in  connection  with  the Offering, and (iii)
represents and covenants that it has, on behalf of the Company, timely made (and
will  continue to timely make) all filings required to be made by the Company in
order  to  make  the  Offering  exempt  from  the registration and qualification
requirements of all applicable federal and state securities laws, and  that such
filings  comply  (and  will comply) with the applicable requirements of all such
laws.

     8.     Waiver, Amendment.  Neither this Agreement nor any provisions hereof
            -----------------
shall  be modified, changed, discharged or terminated except by an instrument in
writing  signed  by  the  party  against  whom  any waiver, change, discharge or
termination  is  sought.

     9.     Assignability.  The Purchaser shall not assign or otherwise transfer
            -------------
this  Agreement,  any  of the Purchaser Securities (or any of the Warrant Shares
issuable  upon  exercise  of the Warrants included therein), or the Registration
Rights  Agreement,  any  interest  in  the  foregoing,  or  any of his rights or
obligations  thereunder,  without  the  prior  written  consent  of the Company.

             -------------------------
Note  included  in the Purchaser Securities, the term "Financing" shall have the
meaning  stated in clause (i)(a) of Recital A to this Agreement, except that all

a  pari-passu basis with the Purchaser and such other Investors, in the security

either  by PMG or by a majority in interest (determined by reference to the then
