                           CLASS A REDEEMABLE WARRANTS
                            TO PURCHASE COMMON STOCK

                             RATEXCHANGE CORPORATION

     THESE WARRANTS ARE ISSUED  PURSUANT TO AN EXEMPTION  FROM THE  REGISTRATION
     PROVISIONS OF THE  SECURITIES ACT OF 1933 AND  QUALIFICATION  PROVISIONS OF
     APPLICABLE  STATE  SECURITIES  LAWS.  NEITHER THEY NOR THE SHARES OF COMMON
     STOCK  FOR  WHICH  THEY  CAN BE  EXERCISED  MAY BE  SOLD,  HYPOTHECATED  OR
     OTHERWISE  TRANSFERRED UNLESS REGISTERED  PURSUANT TO THE SECURITIES ACT OF
     1933 AND QUALIFIED UNDER APPLICABLE STATE LAW OR, IN THE OPINION OF COUNSEL
     TO THE COMPANY, AN EXEMPTION THEREFROM IS AVAILABLE.

WHEREAS, at a meeting of the Board of Directors of RateXchange Corporation. (the
"Company") duly called and held on September 19, 2001, the Board  authorized the
granting of XXXXXX  Class A  Redeemable  Warrants  (the "A  Warrants"),  each to
purchase  one share of the  Company's  Common  Stock,  par value  $0.0001,  (the
"Common  Stock") to XXXXXXXX  (the  "Holder") in  accordance  with the terms set
forth herein; and

WHEREAS,  these A  Warrants  are part of a series of A Warrants  (the  "Series A
Warrants"),  all with the same terms and  conditions  as those set forth herein,
which may be issued by the Company  exercisable  for up to an aggregate  818,750
shares of Common Stock; and

WHEREAS,  the Series A Warrants  are a part of an  offering by the Company of 65
units (the "Units") each consisting of (i) one 12% Convertible Subordinated Note
(collectively the "Notes") in the principal amount of $50,000; and (ii) 12,500 A
Warrants; and

WHEREAS,  each A Warrant permits the holder thereof, for a period terminating on
December 31, 2004, to purchase one share  (collectively  the "A Warrant Shares")
of Common Stock, initially at $0.37 per share; and

WHEREAS,  the Company  desires to set forth the terms of the A Warrants  and the
Holder desires to accept such terms;

NOW,  THEREFORE,  in consideration of the premises,  the parties hereto agree as
follows:

1. Grant of Warrants.

The  Company  hereby  grants to the Holder the right to  purchase  one A Warrant
Share for each A Warrant  granted hereby for a price equal to $0.37 per share as
hereinafter  adjusted (the "Exercise  Price").  The A Warrants may be exercised,
except as otherwise provided

herein,  in whole or in part at any time  commencing  upon the date  hereof  and
terminating  at 5:00 P.M.,  New York time, on December 31 2004 (the  "Expiration
Date").

2. Manner of Exercise.

The A Warrants  underlying this A Warrant Agreement may be exercised in whole or
in part by surrender of this A Warrant Agreement,  with the form of subscription
at the end hereof duly  executed by the Holder,  to the Company at its principal
office or at the office of its stock transfer  agent,  accompanied by payment in
full in cash or by certified or official  bank check to the order of the Company
of the Exercise Price of the shares to be purchased. As soon as practicable, but
in no event more than 15 days after the Holder has given the  aforesaid  written
notice and made the aforesaid payment, the Company shall, without charging stock
issue or transfer  taxes to the Holder,  issue or caused to be issued the number
of shares of duly  authorized  Common Stock issuable upon such  exercise,  which
shall be duly issued,  fully paid and  non-assessable,  and shall deliver to the
Holder a certificate or certificates therefor,  registered in the Holder's name.
In the event of a partial  exercise  of this A Warrant  Agreement,  the  Company
shall also issue and  deliver  to the Holder a new A Warrant  Agreement  of like
tenor,  in the name of the Holder,  for the  exercise of the number of A Warrant
Shares for which such A Warrant Agreement may still be exercised.

3. Investment Representation.

The Holder  acknowledges that the A Warrants underlying this A Warrant Agreement
as well as the A Warrant  Shares for which  these A Warrants  may be  exercised,
have not been and, except as otherwise  provided herein,  will not be registered
under the Securities Act of 1933 (the "Act") or qualified under applicable state
securities  laws and that  the  transferability  thereof  is  restricted  by the
registration  provisions  of the  Act as well as such  state  laws.  The  Holder
represents  that he is  acquiring  the A Warrants and will acquire the A Warrant
Shares for his own account,  for investment purposes only and not with a view to
resale  or  other  distribution  thereof,  nor with the  intention  of  selling,
transferring  or otherwise  disposing of all or any part of such  securities for
any particular event or circumstance,  except selling, transferring or disposing
of them upon full  compliance  with all  applicable  provisions  of the Act, the
Securities  Exchange Act of 1934 (the "Exchange Act"), the Rules and Regulations
promulgated  by  the  Securities  and  Exchange  Commission  (the  "Commission")
thereunder,  and any  applicable  state  securities  laws.  The  Holder  further
understands  and agrees that (i) neither the A Warrants nor the A Warrant Shares
may be sold unless they are subsequently  registered under the Act and qualified
under any applicable  state  securities laws or, in the opinion of the Company's
counsel,  an exemption from such  registration  and  qualification is available;
(ii) any routine  sales of the Company's  securities  made in reliance upon Rule
144  promulgated  by the  Commission  under the Act, can be effected only in the
amounts set forth in and pursuant to the other terms and  conditions,  including
applicable  holding  periods,  of that Rule;  and (iii) except as otherwise  set
forth  herein,  the Company is under no obligation to register the A Warrants or
the A Warrant  Shares  on his  behalf or to  assist  him in  complying  with any
exemption  from  registration  under  the  Act.  The  Holder  agrees  that  each
certificate  representing  any A Warrant  Shares for which the A Warrants may be
exercised will bear on its face a

legend in substantially the following form:

     These  securities have not been registered under the Securities Act of 1933
     or  qualified  under  any  state  securities  laws.  They  may not be sold,
     hypothecated  or  otherwise  transferred  in the  absence  of an  effective
     registration  statement under that Act or  qualification  under  applicable
     state  securities  laws  without  an opinion  acceptable  to counsel to the
     Company that such registration and qualification are not required.

4. Holder Not Deemed Stockholder.

The Holder  shall not,  as holder of the A  Warrants,  be entitled to vote or to
receive  dividends,  except as may be provided in Section 5 below,  or be deemed
the holder of Common Stock that may at any time be issuable upon exercise of the
A Warrants for any purpose  whatsoever,  nor shall anything  contained herein be
construed  to confer  upon the Holder,  as holder of the A Warrants,  any of the
rights of a stockholder  of the Company or any right to vote for the election of
directors or upon any matter  submitted to stockholders at any meeting  thereof,
or to give or  withhold  consent  to any  corporate  action  (whether  upon  any
recapitalization,  issue or  reclassification  of stock,  change of par value or
change  of  stock  to no par  value,  consolidation,  merger  or  conveyance  or
otherwise),  or to  receive  notice of  meetings,  or to  receive  dividends  or
subscription  rights,  until the Holder shall have  exercised the A Warrants and
been issued shares of Common Stock in accordance with the provisions hereof.

5. Warrant Adjustments.

The Exercise Price and the number of shares  purchasable  upon exercise of the A
Warrants  shall be subject to  adjustment  with respect to events after the date
hereof as follows:

(a) Adjustment  for Change in Capital  Stock.  Except as provided in Paragraph 5
(n) below, if the Company shall (i) declare a dividend on its outstanding Common
Stock in shares of its capital  stock,  (ii)  subdivide its  outstanding  Common
Stock,  (iii)  combine its  outstanding  Common  Stock into a smaller  number of
shares, or (iv) issue any shares of its capital stock by reclassification of its
Common  Stock  (including  any  such   reclassification  in  connection  with  a
consolidation  or merger in which the  Company is the  continuing  corporation),
then in each such case the Exercise  Price in effect  immediately  prior to such
action shall be adjusted so that if the A Warrants are thereafter exercised, the
Holder  may  receive  the  number  and kind of shares  which he would have owned
immediately following such action if he had exercised the A Warrants immediately
prior to such action.  Such adjustment shall be made successively  whenever such
an event shall occur. The adjustment shall become  effective  immediately  after
the record date in the case of a dividend or distribution and immediately  after
the   effective   date  in  the   case   of  a   subdivision,   combination   or
reclassification.  If after an  adjustment  the Holder  upon  exercise  of the A
Warrants  may  receive  shares of two or more  classes of  capital  stock of the
Company,  the Company's Board of Directors shall determine the allocation of the
adjusted  Exercise  Price  between  the  classes  of capital  stock.  After such
allocation, the

                                  Page 3 of 13
<PAGE>
Common Stock Purchase Warrant (Series A)                              F 10.25.01
issued by RateXchange Corporation
to XXXXXXX

Exercise  Price of each class of capital  stock shall  thereafter  be subject to
adjustment  on terms  comparable  to those  applicable  to Common  Stock in this
Section 5.

(b)  Adjustment for Certain  Issuances of Common Stock.  If the Company shall at
any time or from time to time  issue any  shares of  Common  Stock  (other  than
shares  issued as a dividend or  distribution  as  provided  in  Paragraph 5 (a)
above) for a  consideration  per share less than the lower of the Exercise Price
in effect on the date of such issue or the Current  Market  Price (as defined in
Paragraph (e) of this Section 5) per share of Common Stock, then, forthwith upon
such issue, the Exercise Price in effect  immediately  prior to such action (the
"Existing  Exercise  Price")  shall be reduced  by: (x)  dividing  the number of
shares so issued by the total number of shares  outstanding after such issuance,
(y)  multiplying  the  quotient  by the amount,  if any,  by which the  Existing
Exercise  Price exceeds the price of the shares so issued,  and (z)  subtracting
the result of (x) and (y) from the Existing  Exercise  Price.  In the case of an
issue of additional shares of Common Stock for cash, the consideration  received
by the Company therefor shall be deemed to be the net cash proceeds received for
such shares, after deducting therefrom any and all commissions and expenses paid
or incurred by the Company for any  underwriting  of, or otherwise in connection
with, the issue of such shares.  The term "issue" shall be deemed to include the
sale or other disposition of shares held in the Company's  treasury.  The number
of  shares  outstanding  at any  given  time  shall  not  include  shares in the
Company's treasury.

     (c) Subscription  Offerings.  In case the Company shall issue to all of its
existing stockholders or otherwise grant rights,  options, or warrants entitling
the holders  thereof to subscribe  for or purchase  Common Stock (or  securities
convertible  into or  exchangeable  for  Common  Stock) at a price per share (or
having a conversion price per share, in the case of a security  convertible into
or exchangeable for Common Stock) less than the lower of the then Exercise Price
or the Current  Market Price per share on the record date for the  determination
of stockholders  entitled to receive such rights,  or granting date, as the case
may be,  then in each  such  case  the  Exercise  Price  shall  be  adjusted  by
multiplying  the Exercise  Price in effect  immediately  prior to such record or
granting  date by a  fraction,  of which the  numerator  shall be the  number of
shares of Common  Stock  outstanding  on such record or  granting  date plus the
number of shares of Common Stock which the aggregate offering price of the total
number of shares of Common  Stock so to be  offered  (or the  aggregate  initial
conversion price of the convertible  securities so to be offered) would purchase
at such Exercise Price or Current Market Price, as the case may be, and of which
the  denominator  shall be the number of shares of Common Stock  outstanding  on
such  record or  granting  date plus the number of  additional  shares of Common
Stock to be offered for  subscription or purchase (or into which the convertible
or  exchangeable  securities  so to be  offered  are  initially  convertible  or
exchangeable).  Such adjustment  shall become effective at the close of business
on such record or granting  date;  provided,  however,  that,  to the extent the
shares of Common  Stock (or  securities  convertible  into or  exchangeable  for
shares  of  Common  Stock)  are not  delivered,  the  Exercise  Price  shall  be
readjusted after the expiration of such rights,  options,  or warrants (but only
to the extent that the A Warrants are not exercised after such  expiration),  to
the Exercise Price which would then be in effect had the  adjustments  made upon
the issuance of such rights or warrants  been made upon the basis of delivery of
only

the  number  of  shares  of Common  Stock  (or  securities  convertible  into or
exchangeable  for  shares  of  Common  Stock)  actually  issued.   In  case  any
subscription  price may be paid in a consideration part or all of which shall be
in a form  other  than  cash,  the  value  of  such  consideration  shall  be as
determined in good faith by the Company's  Board of Directors.  Shares of Common
Stock  owned by or held for the  account of the  Company  or any  majority-owned
subsidiary  shall  not be  deemed  outstanding  for  the  purpose  of  any  such
computation.

     (d)  Other  Rights to  Acquire  Common  Stock.  In case the  Company  shall
distribute to all holders of its Common Stock  evidences of its  indebtedness or
assets (excluding cash dividends or distributions paid from retained earnings of
Maker)  or  rights  or  warrants  to  subscribe  for or  purchase  Common  Stock
(excluding those referred to in Paragraph (c) above), then in each such case the
Exercise  Price  shall be  adjusted  so that  the same  shall  equal  the  price
determined by multiplying the Exercise Price in effect  immediately prior to the
date of such  distribution  by a fraction  of which the  numerator  shall be the
Current Market Price per share (as defined in Paragraph (e) below) of the Common
Stock on the Record Date  mentioned  below less the then fair  market  value (as
determined  by the Board of  Directors  of the  Company)  of the  portion of the
assets or evidences of indebtedness so distributed or of such rights or warrants
applicable  to one  share of  Common  Stock,  and the  denominator  shall be the
Current Market Price per share of the Common Stock. Such adjustment shall become
effective   immediately   after  the  Record  Date  for  the   determination  of
shareholders entitled to receive such distribution.

     (e)  Current  Market  Price.  For  the  purpose  of any  computation  under
Paragraphs (b) through (d) of this Section 5, the Current Market Price per share
of  Common  Stock on any date  shall be deemed  to be the  average  of the daily
closing  prices for the 30 consecutive  trading days  commencing 45 trading days
before  such date.  The  closing  price for each day shall be the last  reported
sales price  regular way or, in case no such  reported  sale takes place on such
day, the closing bid price regular way, in either case on the principal national
securities  exchange on which the Common  Stock is listed or admitted to trading
or, if the Common  Stock is not listed or  admitted  to trading on any  national
securities exchange, the highest reported bid price as furnished by the National
Association of Securities Dealers,  Inc. through NASDAQ or similar  organization
if NASDAQ is no longer  reporting  such  information,  or by the National  Daily
Quotation Bureau or similar  organization if the Common Stock is not then quoted
on an inter-dealer quotation system. If on any such date the Common Stock is not
quoted by any such  organization,  the fair  value of the  Common  Stock on such
date, as determined in good faith by the Company's Board of Directors,  shall be
used.

     (f) Action to Permit  Valid  Issuance of Common  Stock.  Before  taking any
action which would cause an  adjustment  reducing  the Exercise  Price below the
then par value,  if any, of the shares of Common Stock issuable upon exercise of
the A Warrants,  the Company  will take all  corporate  action which may, in the
opinion of its  counsel,  be necessary in order that the Company may validly and
legally issue shares of such Common Stock at such adjusted Exercise Price.

issued by RateXchange Corporation
to XXXXXXX

     (g)  Minimum  Adjustment.  No  adjustment  in the  Exercise  Price shall be
required if such  adjustment  is less than $0.05;  provided,  however,  that any
adjustments,  which by reason of this Paragraph (g) are not required to be made,
shall be carried  forward and taken into account in any  subsequent  adjustment.
All  calculations  under this  Section 5 shall be made to the nearest cent or to
the  nearest  one-hundredth  of a share,  as the case  may be.  Anything  to the
contrary notwithstanding,  the Company shall be entitled to make such reductions
in the conversion  price, in addition to those required by this Paragraph 5 (g),
as it in its discretion  shall determine to be advisable in order that any stock
dividends,  subdivision of shares,  distribution  of rights to purchase stock or
securities,  or distribution of securities  convertible into or exchangeable for
stock hereafter made by the Company to its stockholders shall not be taxable.

     (h)  Referral  of  Adjustment.  In any case in which  this  Section 5 shall
require  that an  adjustment  in the  Exercise  Price be made  effective as of a
record  date for a specified  event (the  "Exercise  Event"),  if the A Warrants
shall have been exercised after such record date, the Company may elect to defer
until the occurrence of the Exercise Event issuing to the Holder the shares,  if
any,  issuable  upon the  Exercise  Event  over and  above the  shares,  if any,
issuable upon such  exercise on the basis of the Exercise  Price in effect prior
to such  adjustment;  provided,  however,  that the Company shall deliver to the
Holder a due bill or other appropriate  instrument evidencing the Holder's right
to receive such additional shares upon the occurrence of the Exercise Event.

     (i) Number of  Shares.  Upon each  adjustment  of the  Exercise  Price as a
result of the calculations made in Paragraphs (a) through (d) of this Section 5,
the A Warrants shall thereafter evidence the right to purchase,  at the adjusted
Exercise  Price,  that number of shares  (calculated to the nearest  thousandth)
obtained by  dividing  (i) the product  obtained  by  multiplying  the number of
shares  purchasable  upon exercise of the A Warrants  prior to adjustment of the
number of shares by the  Exercise  Price in effect  prior to  adjustment  of the
Exercise Price by (ii) the Exercise Price in effect after such adjustment of the
Exercise Price.

     (j) Transactions Not Requiring Adjustments.  No adjustment need be made for
a transaction referred to in Paragraphs (a) through (d) of this Section 5 if the
Holder  is  permitted  to  participate  in the  transaction  on a basis  no less
favorable  than any other party and at a level which would preserve the Holder's
percentage  equity  participation  in the Common  Stock upon  exercise  of the A
Warrants.  No  adjustment  need be made for sales of Common Stock  pursuant to a
Company plan for reinvestment of dividends or interest,  the granting of options
and/or the exercise of options  outstanding under any of the Company's currently
existing stock option plans, the exercise of currently  existing incentive stock
options or  incentive  stock  options  which may be granted in the  future,  the
exercise of any other of the Company's  currently  outstanding  options,  or any
currently authorized warrants, whether or not outstanding. No adjustment need be
made for a change in the par value of the Common Stock,  or from par value to no
par value. If the A Warrants become  exercisable solely into cash, no adjustment
need be made thereafter. Interest will not accrue on the cash.

     (k)  Voluntary  Reduction.  The  Company  from time to time may  reduce the
Exercise Price by any amount for any period of time if the period is at least 20
days and if the  reduction  is  irrevocable  during  the  period.  Whenever  the
Exercise Price is reduced,  the Company shall mail to the Holder a notice of the
reduction.  The  Company  shall mail the notice at least 15 days before the date
the reduced  Exercise  Price takes  effect.  The notice  shall state the reduced
Exercise Price and the period it will be in effect.  A reduction of the Exercise
Price does not  change or adjust  the  Exercise  Price  otherwise  in effect for
purposes of Paragraphs 5 (a) through (d) above.

     (l) Prohibition  against Certain Reductions of Exercise Price.  Anything to
the  contrary  notwithstanding,   for  the  purpose  of  any  computation  under
Paragraphs  (b),  (c) or (k) of this  Section 5, in no event shall the  Exercise
Price be reduced  below (x) the Closing  Price per Share of the Common  Stock on
the date the  Company  executes  this  Warrant as set forth below or (y) the par
value of the Common Stock.

     (m) Notice of  Adjustments.  Whenever the Exercise  Price is adjusted,  the
Company shall  promptly mail to the Holder a notice of the  adjustment  together
with a certificate  from the Company's Chief  Financial  Officer briefly stating
(i) the facts requiring the adjustment, (ii) the adjusted Exercise Price and the
manner of  computing  it;  and (iii) the date on which such  adjustment  becomes
effective.  The certificate shall be prima facia evidence that the adjustment is
correct, absent manifest error.

     (n) Reorganization of Company.  If the Company and/or the holders of Common
Stock are parties to a merger,  consolidation  or a transaction in which (i) the
Company transfers or leases  substantially  all of its assets;  (ii) the Company
reclassifies or changes its outstanding  Common Stock; or (iii) the Common Stock
is  exchanged  for  securities,  cash or other  assets;  the  person  who is the
transferee or lessee of such assets or is obligated to deliver such  securities,
cash or other assets shall assume the terms of the A Warrants.  If the issuer of
securities  deliverable  upon  exercise of the A Warrants is an affiliate of the
surviving,  transferee  or lessee  corporation,  that issuer  shall join in such
assumption.  The assumption agreement shall provide that the Holder may exercise
the A Warrants  into the kind and  amount of  securities,  cash or other  assets
which he would have owned immediately after the consolidation, merger, transfer,
lease or  exchange if he had  exercised  the A Warrants  immediately  before the
effective date of the  transaction.  The assumption  agreement shall provide for
adjustments  that  shall be as  nearly  equivalent  as may be  practical  to the
adjustments  provided for in this Section 5. The successor company shall mail to
the  Holder  a notice  briefly  describing  the  assumption  agreement.  If this
Paragraph applies, Paragraph 5 (a) above does not apply.

     (o)  Dissolution,  Liquidation.  In the event of the  dissolution  or total
liquidation  of the  Company,  then  after the  effective  date  thereof,  the A
Warrants and all rights thereunder shall expire.

     (p)  Notices.  If (i) the Company  takes any action  that would  require an
adjustment in the Exercise  Price pursuant to this Section 5; or (ii) there is a
liquidation or dissolution of the Company,  the Company shall mail to the Holder
a notice stating the

                                  Page 7 of 13

Common Stock Purchase Warrant (Series A)                              F 10.25.01

to XXXXXXX

proposed record date for a distribution or effective date of a reclassification,
consolidation,  merger, transfer, lease, liquidation or dissolution. The Company
shall mail the  notice at least 15 days  before  such date.  Failure to mail the
notice or any defect in it shall not affect the validity of the transaction.

     (q) Determination by Company Conclusive. Any determination that the Company
or its  Board  of  Directors  must  make  pursuant  to this  Section  5 shall be
conclusive, absent manifest error.

6. Fractional Shares.

If the  number  of A  Warrant  Shares  purchasable  upon the  exercise  of the A
Warrants  is  adjusted   pursuant  to  Section  5  hereof,   the  Company  shall
nevertheless not be required to issue fractions of shares upon exercise of the A
Warrants or otherwise,  or to distribute  certificates that evidence  fractional
shares. Instead the Company will round any fractional share to the nearest share
so that if the  fraction  is less than 0.5 no share  shall be issued  and if the
fraction is 0.5 or higher the Company shall issue one full share

7.  Inclusion  of  A  Warrant  Shares  in  Registration   Statement;   Right  to
Registration.

(a) Holder's Right to Registration. Commencing on the date hereof and ending one
year  after the date on which all of the A Warrants  have  expired  and/or  been
exercised,  upon receipt of written notice (the  "Registration  Request Notice")
requesting  registration  under the Act of the shares of Common  Stock  issuable
upon  conversion  of the  Notes  and  the A  Warrant  Shares  (collectively  the
"Registerable Securities") from the holders of more than 50% of the Registerable
Securities,  the Company will offer to the Holder the opportunity to include his
Registerable  Securities  in  such  registration.   The  Company  will  use  its
reasonable  best efforts to file with the Commission as promptly as practicable,
a registration statement (the "Demand Registration Statement"), and will use its
reasonable  best  efforts to have the  Demand  Registration  Statement  declared
effective and remain effective until the earliest of two years  thereafter,  the
date that all the Registerable Securities registered thereby have been sold, or,
in the reasonable opinion of the Company's counsel, the Registerable  Securities
may be sold  publicly  without  registration.  The  Company  will  also  use its
reasonable  best  efforts  to  qualify  the  Registerable  Securities  under the
securities  laws of the state where the Holder  resides  provided the Company is
not  required  to  execute a general  consent  to  service  or to  qualify to do
business  in such state.  This offer to the Holder  shall be made within 20 days
after  the  Company  receives  the  Registration  Request  Notice.  This  Demand
Registration  right may be  exercised  one time only.  If the  Holder  elects to
include his Registerable  Securities in the Demand  Registration  Statement,  he
will,  in a timely  manner,  provide  the  Company  and its  counsel  with  such
information  and execute such documents as the Company's  counsel may reasonably
require to prepare and process the Demand Registration  Statement. If the Holder
elects not to include his  Registerable  Securities in the "Demand  Registration
Statement,"  he  shall  have  no  further  rights  to  the  registration  of his
Registerable  Securities  under  this  Paragraph  7 (a).  In the event  that the
Company has filed a registration  statement with the Commission  relating to its
securities  within 90 days

prior to its receipt of the  Registration  Request  Notice,  which  registration
statement  has not been declared  effective,  the Holder agrees that the Company
can  thereafter  delay the filing of the  Demand  Registration  Statement  for a
period not to exceed 90 days.  Anything to the contrary  notwithstanding,  in no
event shall the Company be required to file a Demand Registration Statement with
the Commission prior to 180 days after the date hereof.

     (b) "Piggy Back" Registration Rights. If at any time after the date hereof,
the Company proposes to file a Registration Statement under the Act with respect
to any of its  securities  (except one relating to employee  benefit  plans or a
merger or similar transaction), it shall give written notice of its intention to
effect  such  filing  to the  Holder  at least  30 days  prior  to  filing  such
Registration  Statement  (the  "Piggy-Back  Registration  Statement").   If  the
Holder's Registerable Securities have not been previously registered as provided
in Paragraph 7 (a) above, and he desires to include his Registerable  Securities
in the Piggy-Back Registration Statement, he shall notify the Company in writing
within 15 days after receipt of such notice from the Company, in which event the
Company shall  include the Holder's  Registerable  Securities in the  Piggy-Back
Registration  Statement.  If the  Holder  elects  to  include  his  Registerable
Securities in the  Piggy-Back  Registration  Statement as set forth  herein,  he
shall,  in a timely  fashion,  provide the  Company  and its  counsel  with such
information and execute such documents as its counsel may reasonably  require to
prepare and process the Piggy-Back Registration Statement.

     (c) Copies of Registration  Statements and  Prospectuses.  The Company will
provide  the  Holder  with  a copy  of  the  Demand  Registration  Statement  or
Piggy-Back  Registration  Statement,  as the  case  may be,  and any  amendments
thereto,  and copies of the final prospectus included therein in such quantities
as may  reasonably  be  required  to permit the Holder to sell his  Registerable
Securities after the Demand  Registration  Statement or Piggy-Back  Registration
Statement, as the case may be, is declared effective by the Commission.

     (d) The Company's Obligation to Bear Expenses of Registration.  The Company
will bear all expenses (except  underwriting  discounts and commission,  if any,
and the legal fees and expenses, if any, of counsel to the Holder) necessary and
incidental to the performance of its obligations under this Section 7.

     (e)   Indemnification.   The  Company  and  the  Holder,  if  the  Holder's
Registerable  Securities  are included in a Registration  Statement  pursuant to
this  Section 7,  shall  provide  appropriate  cross  indemnities  to each other
covering the  information  supplied by the  indemnifying  party for inclusion in
such Registration Statement.

     (f) Restriction on Sale of Registerable Securities.  The Holder agrees that
as a condition  for the  Company  registering  the  Registerable  Securities  as
provided  in  Paragraph  7 (b),  in the event that the  Piggy-Back  Registration
Statement  in which the  Registerable  Securities  are  included  relates  to an
offering to be effected  through or with the  assistance of an  underwriter,  he
will consent to restrict the sale of the Registerable

Securities or reduce the number of Registerable  Securities that may be included
in such registration in accordance with the requirements of such underwriter.

     (g)  Cancellation  of  Registration   Rights.   Anything  to  the  contrary
notwithstanding,  the Company shall not be required to register any Registerable
Securities  which, in the reasonable  opinion of the Company's  counsel,  may be
sold pursuant to the exemption from registration provided by Section (k) of Rule
144 promulgated under the Act.

Stock equals or exceeds  5.4054 times the then Exercise Price for a period of 20
consecutive  trading  days  ending  three  trading  days  prior to the notice of

on the  principal  national  securities  exchange  on which the Common  Stock is
listed or admitted to trading or, if the Common  Stock is not listed or admitted
to trading on any national securities  exchange,  the highest reported bid price
as furnished by the National  Association of Securities  Dealers,  Inc.  through
NASDAQ  or  similar   organization  if  NASDAQ  is  no  longer   reporting  such
information,  or by the National Daily Quotation Bureau or similar  organization
if the Common Stock is not then quoted on an inter-dealer  quotation system. All
unexercised  A Warrants  in the Series of A Warrants  must be  redeemed if any A
Warrants are redeemed.

     (b) Method of Redemption.  In case the Company shall desire to exercise its
right to redeem  the A  Warrants,  it shall mail a notice of  redemption  to the
Holder,  first class,  postage  prepaid,  not later than the 30th day before the
date fixed for redemption, at his last address as shall appear in the records of
the  Company.  Any  notice  mailed  in  the  manner  provided  herein  shall  be
conclusively presumed to have been duly given whether or not the Holder receives
such notice.

     (c) Notice of  Redemption.  The notice of redemption  shall specify (i) the
Redemption Price; (ii) the date fixed for redemption;  (iii) the place where the
A Warrant  Certificates  shall be delivered and the  Redemption  Price paid; and
(iv) that the right to exercise the A Warrants  shall  terminate at 5:00 PM (New
York time) on the date fixed for  redemption.  The date fixed for the redemption
of the A Warrants shall be the Redemption Date.

     (d)  Termination  of Right to Exercise A Warrants.  Any right to exercise A

behalf of the Holder of one or more A Warrants to be redeemed,  deliver or cause

to the  Redemption  Price of each such A Warrant.  From and after the Redemption
Date and upon the deposit or setting aside by the Company of a sum sufficient to
redeem all of the A Warrants called for redemption, such A Warrants shall expire
and become void and all rights hereunder, except the right to receive payment of
the Redemption Price, shall cease.

9. Covenants of the Company.

The Company  covenants  that it will at all times reserve and keep available out
of its authorized Common Stock, solely for the purpose of issue upon exercise of
a Warrants, such number of shares of Common Stock as shall then be issuable upon
the  exercise of all  outstanding  a Warrants.  The Company  covenants  that all
shares of Common Stock which shall be issuable  upon  exercise of the A Warrants
shall,  at the time of delivery  thereof,  be duly and validly  issued and fully
paid and  nonassessable  and free from all preemptive or similar rights,  taxes,
liens and charges with respect to the issue thereof, and that upon issuance such
shares shall be listed on each securities  exchange,  if any, on which the other
shares of outstanding Common Stock of the Company are then listed.

10. Amendments.

This Agreement shall not be amended,  modified or revoked except by agreement in
writing, signed by the Company and the Holder.

11. Governing Law.

The A Warrants shall be governed by the laws of the State of California.

IN WITNESS  WHEREOF,  the Company has caused  these A Warrants to be executed on
its behalf by an officer  thereunto duly  authorized and the Holder has executed
this Agreement as of November 26, 2001.

                            PLACEMENT AGENT AGREEMENT

                                              Dated as of November 28, 2001

Murphy & Durieu
120 Broadway
17th Floor

New York, New York  10271
Attention: Lawrence Stanton

Ladies and Gentlemen:

     The  undersigned,  RateXchange  Corporation,  a Delaware  corporation  (the
"Company"),  hereby  agrees  with  Murphy & Durieu  (the  "Placement  Agent") as
follows:

1.   Offering.

     A. The Company hereby  engages the Placement  Agent to act as its exclusive
placement  agent in  connection  with the  issuance and sale by the Company (the
"Offering") of sixty-five (65) units (the "Units") of the Company's  securities,
at a price of $50,000 per Unit, including (a) sixty (60) Units in a closing held
November  26,  2001 (the "First  Closing"),  and (b) five (5) Units in a closing
held November 28, 2001 (the "Second  Closing";  together with the First Closing,
the  "Closings"  and  each,  a  "Closing").  Each  Unit  consists  of (i) a note
(collectively  the "Notes") in the principal  amount of $50,000 bearing interest
at an annual rate of 12% and  convertible  into the Company's  common stock (the
"Common  Stock"),  par  value at  $0.0001  per  share  (collectively,  the "Note
Shares"),  at a  conversion  price  equal to $0.37  per share  (the  "Conversion
Price"),  representing  the  higher of (x) $0.35 per share and (y) the per share
price of the Common Stock as  evidenced by the last trade on the American  Stock
Exchange   prior  to  the   relevant   Closing,   and  (ii)  12,500  A  warrants
(collectively,  the  "Warrants"),  each to purchase one share of Common Stock at
the Conversion  Price (such Common Stock  underlying the Warrants,  the "Warrant
Shares").  The Units are subject to the terms of the Subscription  Agreement and
Investment  Letter,  prepared by the Company (such  agreement  together with all
amendments thereof and supplements and exhibits thereto is referred to herein as
the  "Subscription  Agreement") to be executed by each purchaser and the Company
and in the  certificates/instruments  representing the securities underlying the
Units. The Units, including the underlying Notes, Note Shares, Warrants, Warrant
Shares and the securities  issued pursuant to the Placement Agent's Warrants (as
defined  below)  are  hereinafter  sometimes  collectively  referred  to as  the
"Securities."  The Securities  will be offered  without  registration  under the
Securities Act of 1933 (the "Securities  Act").  Purchasers of the Units will be
granted certain registration rights with respect to the Securities as more fully
set forth in the Subscription  Agreements and in the  certificates  representing
the Securities.

     B. The Units will be offered on a "best  efforts"  basis.  The Company will
issue the appropriate number of Units, Notes and Warrants at each Closing, after
subscriptions have been received and accepted by the Company.  Each Closing will
take place at the offices of Kelley Drye & Warren LLP,  counsel to the Placement
Agent,  at 101 Park  Avenue,  New York,  New York 10178 or such  other  place as
determined  by the Company  and the  Placement  Agent,  at such time as shall be
determined by the Placement Agent.

     C. The Offering  commenced on or about October 25, 2001 and shall terminate
on November 30, 2001, it being  acknowledged  that the offering was to terminate
on October 31, 2001,  but was extended by the mutual  consent of the Company and
the  Placement  Agent (such date,  as the same may be extended,  is  hereinafter
referred to as the "Termination Date"; the period commencing on October 25, 2001
and  ending  on the  Termination  Date is  sometimes  referred  to herein as the
"Offering Period").

<PAGE>

     D. As compensation  for its placement of the Offering,  the Placement Agent
shall receive a commission of $325,000 (the "Commission"),  equal to ten percent
(10%) of the gross  proceeds from the Offering.  The Placement  Agent also shall
receive  a   non-accountable   expense   allowance  of  $97,500  (the   "Expense
Allowance"),  equal to three percent (3%) of the gross proceeds from the sale of
the Units. The parties hereto  acknowledge that $25,000 of the Expense Allowance
was advanced to the Placement Agent on November 21, 2001.

2.   Information.

     A. The Units will be offered on a "best efforts" basis.

     B. The Units  shall have the terms set forth in and shall be offered by the
Company by means of the Subscription  Agreement.  Payment for the Units shall be
made by check or wire  transfer  as more  fully  described  in the  Subscription
Agreements. The minimum purchase by any purchaser shall be $50,000, or one Unit,
except that subscriptions for partial Units may be accepted at the discretion of
the Company and the Placement  Agent.  The Placement Agent and the Company agree
that the Units will be offered and sold only to  "accredited  investors"  within
the meaning of Rule 501 of Regulation D ("Accredited  Investors") promulgated by
the Securities and Exchange  Commission (the "Commission")  under the Securities
Act and Rule 506 of Regulation D of the Securities Act.

     C. All funds  received in respect of the  subscriptions  for Units that are
closed on will be promptly  forwarded  to the Company,  against  delivery of the
appropriate amount of the Securities offered, net of (i) the Commission and (ii)
the Expense Allowance.

     D. The  Placement  Agent shall not be obligated to sell any Units and shall
only be obligated to offer the Units on a "best efforts" basis.

     E. The  Company  and the  Placement  Agent  reserve the right to reject any
subscriber,  in whole or in part,  in  their  sole  discretion.  Notwithstanding
anything to the contrary  contained in this Section 2(E), the Company's right to
reject a subscriber  shall lapse three (3) days after  receipt by the Company of
the fully completed and duly executed subscription  documents from the Placement
Agent with respect to such  subscriber  (unless it is  determined  subsequent to
such  period  that  such  subscriber  does  not meet  the  investor  suitability
requirements  of  this  Offering).  Funds  received  by  the  Company  from  any
subscriber  whose  subscription is rejected will be returned to such subscriber,
without deduction  therefrom or interest thereon,  but no sooner than such funds
have cleared the banking system in the normal course of business.

     F. At each Closing,  the Company shall also issue and sell to the Placement
Agent  or  its  designee(s),   for  nominal  consideration,   purchase  warrants
("Placement  Agent's  Warrants")  to purchase a number of placement  agent units
(the  "Placement  Agent  Units") of the  Company  equal to 10% of the  aggregate
number of Units sold by the Company to  investors  identified  by the  Placement
Agent at such Closing (the "Placement  Agent's  Warrants"),  under the terms and
conditions set forth in the Placement  Agent's Warrant  Agreement dated the date
of the Second  Closing by and between the Company and the  Placement  Agent (the
"Placement  Agent's  Warrant  Agreement").  The  Company  acknowledges  that the
Placement Agent or its designee(s)  will receive  Placement  Agent's Warrants to
purchase an aggregate of 6.5 Units  (consisting of Placement Agent's Warrants to
purchase 6 Units as part of the First Closing and Placement  Agent's Warrants to
purchase 0.5 Units as part of the Second  Closing).  Each  Placement  Agent Unit
shall consist of (i) up to such number of fully paid and  non-assessable  shares
of Common Stock which is equal to the total number of  securities  issuable upon
conversion  of the  original  principal  amount of a Note issued in the Offering
(whether or not the Notes have been converted and notwithstanding whether or not
the Notes have been repaid) based upon an initial  conversion price equal to the
Conversion Price,  subject to such adjustments as found in the Placement Agent's
Warrant Agreement, and (ii) 12,500 Warrants.

3.   Representations, Warranties and Covenants of the Placement Agent.

     A. The Placement Agent represents, warrants and covenants as follows:

                                       2
<PAGE>

          (i) The  Placement  Agent has the  necessary  power to enter into this
Agreement  and the Placement  Agent's  Warrant  Agreement and to consummate  the
transactions contemplated hereby and thereby.

          (ii)  The  execution  and  delivery  by the  Placement  Agent  of this
Agreement and the Placement Agent's Warrant  Agreement,  and the consummation of
the  transactions  contemplated  herein  and  therein  will  not  result  in any
violation  of, or be in  conflict  with,  or  constitute  a default  under,  any
agreement or instrument to which the Placement  Agent is a party or by which the
Placement Agent or its properties are bound, or any judgment,  decree, order or,
to the Placement Agent's knowledge,  any statute,  rule or regulation applicable
to the  Placement  Agent.  This  Agreement  and the  Placement  Agent's  Warrant
Agreement,  when executed and delivered by the Placement Agent,  will constitute
the legal, valid and binding obligations of the Placement Agent,  enforceable in
accordance  with  their  respective  terms,  except to the  extent  that (a) the
enforceability  hereof or  thereof  may be limited  by  bankruptcy,  insolvency,
reorganization,  moratorium  or  similar  laws from  time to time in effect  and
affecting the rights of creditors  generally,  (b) the enforceability  hereof or
thereof is subject to general  principles of equity, or (c) the  indemnification
provisions hereof or thereof may be held to be violative of public policy.

          (iii) The Placement Agent will deliver to each purchaser a copy of the
Subscription   Agreement,   as  it  may  have  been  most  recently  amended  or
supplemented by the Company.

          (iv)  Upon  receipt  of an  executed  Subscription  Agreement  and the
payments representing subscriptions for Units, the Placement Agent will promptly
forward copies of the Subscription  Agreement  (together with all  consideration
received for such Units) to the Company or its counsel.

          (v) The Placement Agent will not deliver the Subscription Agreement to
any person it does not believe to be an Accredited Investor.

          (vi) The Placement Agent will not take any action which,  assuming the
Company's  representation  in Section  4(A)(ii)  hereof is correct,  it believes
would cause the Offering to violate the  provisions of the  Securities  Act, the
Securities and Exchange Act of 1934, (the "Exchange  Act"), the respective rules
and  regulations   promulgated  thereunder  (the  "Rules  and  Regulations")  or
applicable Blue Sky laws of any state or jurisdiction.

          (vii)  The  Placement  Agent  shall  use  all  reasonable  efforts  to
determine (a) whether any  prospective  purchaser is an Accredited  Investor and
(b) that any material  information  furnished by a prospective  investor is true
and accurate.  The  Placement  Agent shall have no obligation to insure that (x)
any check,  note, draft or other means of payment for the Units will be honored,
paid or enforceable  against the subscriber in accordance with its terms, or (y)
subject to the performance of the Placement Agent's obligations and the accuracy
of the Placement  Agent's  representations  and  warranties  hereunder,  (A) the
Offering is exempt from the  registration  requirements of the Securities Act or
any  applicable  state  "Blue Sky" law or (B) any  prospective  purchaser  is an
Accredited Investor.

          (viii) The Placement Agent is a member of the National  Association of
Securities Dealers, Inc. (the "NASD"), and is a broker-dealer registered as such
under the Exchange Act and under the securities  laws of the states in which the
Units will be offered or sold by the  Placement  Agent,  unless an exemption for
such state registration is available to the Placement Agent. The Placement Agent
is in  compliance  with all material  Rules and  Regulations  applicable  to the
Placement Agent generally and applicable to the Placement Agent's  participation
in the Offering.

          (ix)  The  information   contained  in  the  Subscription   Agreements
(including the exhibits  thereto,  other than Exhibit D (the Company's Form 10-Q
for the  quarterly  period ended June 30, 2001) and E (the  Company's  Notice of
Annual Meeting of stockholders  held on May 31, 2001)) relating to the Placement
Agent is complete  and correct  and does not  contain  any untrue  statement  of
material fact or omit to state a material fact required to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading.

outstanding  securities  of the  Company  and the  Subsidiaries,  have been duly
authorized  and validly issued and are fully paid and  non-assessable,  and were
issued in compliance with all applicable  federal and state securities laws; the
holders  thereof have no rights of rescission or preemptive  rights with respect
thereto  and are not  subject to  personal  liability  solely by reason of being
securityholders;  and none of such  securities  were issued in  violation of the
preemptive  rights  of any  holders  of any  security  of the  Company  and  the
Subsidiaries.  The Company has 300,000,000 shares of authorized Common Stock, of
which 18,328,174  shares are outstanding as of the date hereof.  The Company has

Warrants.

          (iii) When  issued in  accordance  with their  respective  terms,  the
Securities will be validly issued,  fully-paid and  non-assessable;  the holders

          (iv) Each of the Company and the  Subsidiaries has good and marketable

security interests and defects of any material nature whatsoever.

          (v) Except as is described in the Company's  public filings,  there is

Company's knowledge, threatened against, or involving the properties or business
of the Company or the Subsidiaries.

          (vi) Each of the Company and the  Subsidiaries has been duly organized

Inc., a Delaware  corporation,  and RateXchange I, Inc., a Delaware corporation,

partnership,  trust, joint venture or other business entity other than as listed
in the  Subscription  Agreement,  except that the Company owns 750,000 shares of
common stock of Telenisus Corporation,  a Delaware corporation that is privately
held. Each of the Company and the Subsidiaries is duly qualified or licensed and
in good  standing as a foreign  corporation  in each  jurisdiction  in which the
character of its operations  requires such  qualification or licensing and where
failure to so qualify  would have a material  adverse  effect on the Company and
the Subsidiaries  taken as a whole. Each of the Company and the Subsidiaries has
all  requisite  corporate  power and  authority,  and all material and necessary
authorizations,  approvals,  orders,  licenses,  certificates and permits of and
from all governmental  regulatory officials and bodies (domestic and foreign) to
conduct its businesses (and proposed  business) as described in the Subscription
Agreement,  and each of the Company and the  Subsidiaries  is doing  business in
material compliance with all such authorizations,  approvals,  orders, licenses,
certificates and permits and all foreign,  federal,  state and local laws, rules
and regulations  concerning the business in which it is engaged. Any disclosures
in the Subscription Agreement concerning the effects of foreign,  federal, state
and local regulation on the Company's or  Subsidiaries'  businesses as currently
conducted and as  contemplated  are correct in all material  respects and do not
omit to state a material fact. The Company has all corporate power and authority
to enter into this Agreement and the other Operative  Documents and to carry out
the   provisions  and   conditions   hereof  and  thereof,   and  all  consents,
authorizations,  approvals  and  orders  required  in  connection  herewith  and
therewith  have  been  obtained  prior  to the  Termination  Date.  No  consent,
authorization or order of, and no filing with, any court,  government  agency or
other body is  required by the Company  for the  issuance of the  Securities  or
execution and delivery of the  Subscription  Agreements,  except for  applicable
federal  and  state  securities  laws.  Neither  the  Company  nor  any  of  the
Subsidiaries  has, since its inception,  incurred any liability arising under or
as a result of the  application of any of the provisions of the Securities  Act,
the Exchange Act or the Rules and Regulations.

          (viii) There has been no material  adverse  change in the condition or
prospects  of the  Company  or any of the  Subsidiaries  except  that all of the
material  assets of Xpit  Corporation  were sold on  October  29,  2001,  either
individually  or as a whole,  financial  or  otherwise,  from that on the latest
dates as of which such  condition or prospects,  respectively,  are set forth in
each of the Subscription Agreements,  and the outstanding debt, the property and
the  businesses  of each of the  Company  and the  Subsidiaries  conforms in all
material  respects to the  descriptions  thereof  contained in the  Subscription
Agreements.

          (ix)  Except  as  otherwise  set forth in the  Subscription  Agreement

Subsidiaries is in breach of, or in default under,  any term or provision of any
indenture, mortgage, deed of trust, lease, note, loan or credit agreement or any
other  agreement or instrument  evidencing an obligation for borrowed  money, or
any other  agreement or  instrument to which it is a party or by which it or any
of its properties  may be bound or affected.  Neither the Company nor any of the
Subsidiaries  is in violation  of any  provision  of its  respective  charter or
Bylaws or in violation of any franchise,  license, permit,  judgment,  decree or
order, or in violation of any statute, rule or regulation. Neither the execution
and delivery of this Agreement,  the Placement  Agent's Warrant  Agreement,  the
Subscription Agreements, the Notes or the Warrants, nor the issuance and sale or
delivery of the  Securities,  nor the  consummation  of any of the  transactions
contemplated herein or in the other Operative  Documents,  nor the compliance by
the Company with the terms and provisions hereof or thereof, as the case may be,
has conflicted  with or will conflict with, or has resulted in or will result in
a breach  of, any of the terms and  provisions  of, or has  constituted  or will
constitute a default under, or has resulted in or will result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Company or any of the  Subsidiaries  or pursuant to the terms of any  indenture,
mortgage,  deed of trust,  note, loan or credit agreement or any other agreement
or  instrument  evidencing  an  obligation  for  borrowed  money,  or any  other
agreement or instrument to which the Company or any of the  Subsidiaries  may be
bound or to which any of the  property  or assets of the  Company  or any of the
Subsidiaries  is subject;  nor will such action  result in any  violation of the
provisions of the respective  charter or the Bylaws of the Company or any of the
Subsidiaries or any statute or any order,  rule or regulation  applicable to the
Company or any of the Subsidiaries of any court or of any

          (x) This Agreement,  the Placement  Agent's Warrant  Agreement and the
Securities  conform in all  material  respects  to all  statements  in  relation

Agreements nor the exhibits  attached  thereto contain any untrue statement of a
material fact or omit to state any material  fact required to be stated  therein

limitation,  any such licenses or rights described in the Subscription Agreement
as being owned or possessed by the Company or any of the Subsidiaries) and there
is no claim or action by any person  pertaining  to, or  proceeding,  pending or
threatened,  which  challenges the exclusive rights of the Company or any of the
Subsidiaries with respect to any trademarks,  service marks, copyrights, service
names,  trade names,  patents,  patent  applications  and  licenses  used in the
conduct  of the  Company's  or any of  the  Subsidiaries  respective  businesses
(including,  without  limitation,  any such licenses or rights  described in the

shall,  within five (5)  business  days,  notify the  indemnifying  party of the
commencement  thereof;  the omission by one  indemnified  party to so notify the
indemnifying party shall not relieve the indemnifying party of its obligation to
indemnify any indemnified party and shall not relieve the indemnifying  party of
any  liability  outside of this  indemnification  if not  materially  prejudiced
thereby.  In the event that any action is brought against the indemnified party,
the  indemnifying  party will be entitled  to  participate  therein  and, to the
extent it may desire,  to assume and control the defense  thereof  with  counsel
chosen by it which is reasonably  acceptable  to the  indemnified  party.  After
notice from the indemnifying  party to such indemnified party of its election to
so assume the defense thereof, the indemnifying party will not be liable to such
indemnified  party  under  such  Section  6(A) or 6(B)  for any  legal  or other
expenses  subsequently incurred by such indemnified party in connection with the
defense thereof, but the indemnified party may, at its own expense,  participate
in such  defense  by  counsel  chosen by it,  without,  however,  impairing  the
indemnifying  party's  control of the  defense.  Subject to the  proviso of this
sentence and  notwithstanding  any other  statement  to the  contrary  contained
herein,  the indemnified  party or parties shall have the right to choose its or
their own counsel  and control the defense of any action,  all at the expense of
the  indemnifying  party if, (i) the  employment of such counsel shall have been
authorized in writing by the  indemnifying  party in connection with the defense
of  such  action  at  the  expense  of  the  indemnifying  party,  or  (ii)  the
indemnifying  party shall not have employed counsel  reasonably  satisfactory to
such  indemnified  party to have charge of the  defense of such action  within a
reasonable  time  after  notice of  commencement  of the  action,  or (iii) such
indemnified  party or parties shall have reasonably  concluded that there may be
defenses available to it or them which are different from or additional to those
available  to one  or  all  of the  indemnifying  parties  (in  which  case  the
indemnifying  parties  shall not have the right to direct  the  defense  of such
action on behalf of the  indemnified  party or parties),  in any of which events
such  fees  and  expenses  of one  additional  counsel  shall  be  borne  by the
indemnifying party; provided, however, that the indemnifying party shall not, in
connection with any one action or separate but substantially  similar or related
actions in the same jurisdiction  arising out of the same general allegations or
circumstance,  be liable for the  reasonable  fees and expenses of more than one
separate  firm of attorneys  at any time for all such  indemnified  parties.  No
settlement of any action or  proceeding  against an  indemnified  party shall be
made without the consent of the indemnifying  party,  provided that such consent
was not reasonably withheld.

     D. In order to provide for just and equitable contribution in circumstances
in which the  indemnification  provided  for in  Section  6(A) or 6(B) is due in
accordance  with  its  terms  but  is for  any  reason  held  by a  court  to be
unavailable on grounds of policy or otherwise, the Company and the Subsidiaries,
on the one hand, and the Placement  Agent, on the other hand shall contribute to
the aggregate losses,  claims, damages and liabilities (including legal or other
expenses  reasonably incurred in connection with the investigation or defense of
same)  which the other may incur,  in such  proportions  as are  appropriate  to
reflect the relative fault of the Company and the Placement  Agent in connection
with the facts which resulted in such losses, liabilities,  claims, damages, and
expenses;  provided,  however,  that if  applicable  law  does not  permit  such
allocation,  then other relevant equitable  considerations  such as the relative
benefits received by the Company, on the one hand and the Placement Agent on the
other hand shall also be  considered.  The  relative  benefits  received  by the
Company,  on the one hand, and the Placement  Agent, on the other hand, shall be
deemed  to be in the same  proportion  as (x) the total  net  proceeds  from the
Offering  (before  deducting  expenses)  received  by the  Company,  and (y) the
Commission  received by the  Placement  Agent  pursuant to Section  1(D) hereof.
Relative fault shall be determined by reference to, among other things,  whether
the untrue or alleged  untrue  statement  of a material  fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or by the Placement Agent, and the parties' relative intent,  knowledge,
access to  information  and  opportunity  to  correct  or  prevent  such  untrue
statement  or  omission.  Notwithstanding  the  foregoing,  no person  guilty of
fraudulent  misrepresentation  within  the  meaning  of  Section  11(f)  of  the
Securities  Act shall be  entitled to  contribution  from any person who was not
guilty of such fraudulent misrepresentation.  For purposes of this Section 6(D),
any person controlling, controlled by or under common control with the Placement
Agent, or any partner, director, officer, employee,  representative or any agent
of any  thereof,  shall have the same rights to  contribution  as the  Placement
Agent and each person  controlling,  controlled by or under common  control with
the Company within the meaning of Section 15 of the Securities Act or Section 20
of the  Exchange  Act and each  officer of the Company and each  director of the
Company  shall have the same rights to  contribution  as the Company.  Any party
entitled to contribution will,  promptly after receipt of notice of commencement
of any action, suit or proceeding against such party in respect of which a claim
for contribution

                                       10
<PAGE>

may be made against the other party under this Section  6(D),  notify such party
from whom  contribution may be sought,  but the omission to so notify such party
shall not  relieve  the  party  from whom  contribution  may be sought  from any
obligation  they  may  have  hereunder  or  otherwise  if the  party  from  whom
contribution may be sought is not materially  prejudiced thereby.  The indemnity
and contribution  agreements  contained in this Section 6 shall remain operative
and in full  force and  effect  regardless  of any  investigation  made by or on
behalf of any indemnified person or any termination of this Agreement.

7.   Payment of Expenses.

     Whether or not the Offering is successfully completed,  except as otherwise
set forth in this Section 7, the Company  hereby  agrees to bear the fees of the
escrow agent equally with the Placement  Agent.  It is agreed that the Placement
Agent's counsel shall perform the required Blue Sky legal  services.  "Blue Sky"
and counsel  fees and expenses  shall be paid by the  Placement  Agent.  In this
connection,  Blue  Sky  applications  for  registration  of  the  Securities  or
exemption  therefrom shall be made in such states and  jurisdictions as shall be
reasonably  requested  by the  Placement  Agent,  provided  that such states and
jurisdictions do not require the Company to qualify as a foreign corporation. In
addition,  the Company  hereby agrees to pay to the Placement  Agent the Expense
Allowance,  of which $13,500 was advanced to the Placement Agent on November 21,
2001.

8.   Conditions of Closing

     Each  Closing  shall be held at the offices of the  Placement  Agent or its
counsel.  The  obligations of the Placement  Agent hereunder shall be subject to
the  continuing  accuracy of the  representations  and warranties of the Company
herein as of the date hereof and as of such  Closing with respect to the Company
as if it had been made on and as of the Closing;  the accuracy on and as of such
Closing of the  statements  of the officers of the Company made  pursuant to the
provisions  hereof;  and the performance by the Company on and as of the Closing
of  its  covenants  and  obligations  hereunder  and to  the  following  further
conditions:

     A. At each Closing,  the Placement Agent shall receive the opinion of Barry
Feiner,  Esq.,  counsel to the  Company,  dated as of the date of such  Closing,
which opinion shall be in form and substance reasonably  satisfactory to counsel
for the Placement Agent, to the effect that:

          (i) The execution,  delivery and  performance of each of the Operative
Documents  has been  duly and  validly  authorized  by the  Company,  including,
without limitation, the corporate power and authority to issue, sell and deliver
the Securities as provided herein and therein.  Each of the Operative  Documents
is a valid and binding agreement of the Company,  enforceable in accordance with
its respective terms, except to the extent that (a) the enforceability hereof or
thereof may be limited by bankruptcy, insolvency, reorganization,  moratorium or
similar laws from time to time in effect and  affecting  the rights of creditors
generally,  (b) the  enforceability  hereof or  thereof  is  subject  to general
principles of equity or (c) the indemnification provisions hereof or thereof may
be held to be violative of public policy. The Placement Agent's Warrants and the
Warrants  constitute  valid and binding  obligations of the Company to issue and
sell,  upon  exercise  thereof and payment  therefor  in  accordance  with their
respective  terms,  the number and type of securities of the Company  called for
thereby.  The  Securities to be issued and sold by the Company  pursuant to this
Agreement,   the  Placement  Agent's  Warrant  Agreement  and  the  Subscription
Agreements  have been duly  authorized  and, when issued in accordance with this
Agreement,   the  Placement  Agent's  Warrant  Agreement  and  the  Subscription
Agreements,  the  certificates/instruments  representing  each of the Securities
will be validly issued,  fully paid and non-assessable;  the holders thereof are
not and will not be subject to personal  liability  to third  parties  solely by
reason of being such holders; such Securities are not and will not be subject to
the  preemptive  rights of any  stockholder  of the Company;  and all  corporate
action  required to be taken for the  authorization,  issuance  and sale of such
Securities  has been  duly and  validly  taken by the  Company.  The  Securities
conform in all material  respects to the  description  thereof  contained in the
Subscription Agreement.

          (ii) The Operative  Documents  conform in all material respects to the
descriptions thereof contained in the Subscription Agreement.

                                       11
<PAGE>

          (iii)  Assuming that each purchaser of the Securities is an Accredited
Investor, that the representations made by the Company, the Subsidiaries and the
Placement  Agent in this  Agreement are true and correct at all times during the
Offering  Period and at the time of such Closing,  that the Placement  Agent has
complied  with  the  provisions  of this  Agreement  and of  Section  502(c)  of
Regulation D and that a Form D will be filed in accordance  with the  provisions
of Section 503 of Regulation D, and that appropriate transfer  restrictions will
be placed on the  certificates/instruments  representing each of the Securities,
no registration under the Securities Act is required in connection with the sale
and issuance of any of the  Securities.  The offering and sale of the Securities
in the manner  contemplated  by this  Agreement,  the Placement  Agent's Warrant
Agreement,  the  Subscription  Agreements and the Warrant  Agreement will not be
integrated  with any offering made before the offer and sale of such  securities
in a manner that would render  unavailable any exemption from registration under
the Securities Act.

          Such counsel shall state that he has  participated in conferences with
officers,  accountants and other representatives of the Company during which the
contents of the Subscription Agreement were discussed.  Although such counsel is
not passing  upon,  and does not assume any  responsibility  for, the  accuracy,
completeness  or  fairness  of any  statements  contained  in  the  Subscription
Agreement, such counsel shall state that, on the basis of the foregoing, nothing
has  come  to  such  counsel's  attention  to  lead  him  to  believe  that  the
Subscription  Agreement,  as of the date  thereof and the date of such  opinion,
contained or contains any untrue  statement of a material fact or omits to state
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein,  in the light of the  circumstances  under  which they were
made, not  misleading  (except for the financial  statements,  notes thereto and
other  statistical  and  financial   information  included  therein  or  omitted
therefrom, as to which such counsel need express no opinion).

     B. At each  Closing,  the  Placement  Agent  shall  receive  the opinion of
Christopher Aguilar, Esq., General Counsel for the Company, dated as of the date
of such  Closing,  which  opinion  shall  be in form  and  substance  reasonably
satisfactory to counsel for the Placement Agent, to the effect that:

          (i) Each of the Company and the  Subsidiaries  has been duly organized
and is validly  existing as a corporation in good standing under the laws of its
respective   jurisdiction  of   organization.   Each  of  the  Company  and  the
Subsidiaries  is duly  qualified or licensed  and in good  standing as a foreign
corporation  in each  jurisdiction  in which its  ownership  or  leasing  of any
properties or the character of its  operations  requires such  qualification  or
licensing.  Each of the Company and the Subsidiaries has all requisite corporate
power  and  authority,  and all  authorizations,  approvals,  orders,  licenses,
certificates and permits of and from all governmental  regulatory  officials and
bodies  (domestic  and foreign) to own or lease its  properties  and conduct its
business (or proposed business) as described in the Subscription Agreement. Each
of the Company and the  Subsidiaries  is doing business in compliance  with such
authorizations,  approvals,  orders, licenses,  certificates and permits and all
federal,  state,  local and foreign laws,  rules and regulations  concerning the
business in which such entity is engaged.

          (ii) Each of the  Company  and the  Subsidiaries  has the  outstanding
capitalization as set forth in the Subscription  Agreement.  Neither the Company
nor any of the Subsidiaries is a party to or bound by any instrument,  agreement
or other  arrangement  providing  for it to issue  any  capital  stock,  rights,
warrants,  options  or  other  securities,  except  for  this  Agreement  and as
described in the  Subscription  Agreement or in the  Company's  filings with the
Commission. All issued and outstanding securities of each of the Company and the
Subsidiaries  have been duly  authorized,  validly issued and are fully paid and
non-assessable,  and were issued in compliance  with all applicable  federal and
state  securities  laws;  the holders  thereof have no rights of  rescission  or
preemptive rights with respect thereto and are not subject to personal liability
solely by  reason of being  securityholders;  and none of such  securities  were
issued in violation of the  preemptive  rights of any holders of any security of
any of the Company or the Subsidiaries.  The Company has (a) 300,000,000  shares
of authorized  Common Stock,  18,278,174 this was the number  outstanding per C.
Aguilar on  11/20/01,  just  needs to be  brought  down] of which are issued and
outstanding  as of the date  hereof,  and (b)  60,000,000  shares of  authorized
preferred  stock,  of  which  2,000,000  shares  of  non  redeemable   Series  A
Convertible  Preferred Stock are issued and outstanding on the date hereof.  The
Company has duly  authorized  and reserved  for  issuance  the Note Shares,  the
Warrant Shares, and the securities underlying the Placement Agent Warrants.

                                       12
<PAGE>

          (iii) Each of the Company and the Subsidiaries owns or possesses, free
and clear of all liens or  encumbrances  and rights  thereto or therein by third
parties,  the requisite licenses or other rights to use all trademarks,  service
marks, copyrights,  service names, trade names, patents, patent applications and
licenses necessary to conduct its business (including,  without limitation,  any
such licenses or rights described in the  Subscription  Agreement as being owned
or possessed by the Company or any of the Subsidiaries,  respectively) and there
is no claim or action by any person  pertaining  to, or  proceeding,  pending or
threatened,  which  challenges the exclusive rights of the Company or any of the
Subsidiaries with respect to any trademarks,  service marks, copyrights, service
names,  trade names,  patents,  patent  applications  and  licenses  used in the
conduct of any of the Company's or any of the Subsidiaries respective businesses
(including,  without  limitation,  any such licenses or rights  described in the
Subscription  Agreement as being owned or possessed by the Company or any of the
Subsidiaries);  none  of  the  Company's  or any  of  the  Subsidiaries  current
products,  services  or  processes  infringe  or will  infringe  on the  patents
currently  held  by  any  third  party.  Neither  the  Company  nor  any  of the
Subsidiaries  is  under  any  obligation  to pay  royalties  or fees or any kind
whatsoever  to any third party with respect to any  trademarks,  service  marks,
copyrights,  service names, trade names, patents, patent applications,  licenses
or technology it has developed, uses, employs or intends to use or employ, other
than to their respective licensors.

          (iv)  Except as  otherwise  publicly  disclosed  by the Company in its
filings with the  Commission,  there is no material  litigation or  governmental
proceeding pending or, to the best of the Company's or Subsidiaries'  knowledge,
threatened  against, or involving the properties or businesses of the Company or
the Subsidiaries.

          (v)  Except as  otherwise  publicly  disclosed  by the  Company in its
filings with the Commission,  neither the Company nor any of the Subsidiaries is
in breach of, or in  default  under,  any term or  provision  of any  indenture,
mortgage,  deed of trust,  lease,  note,  loan or credit  agreement or any other
agreement or  instrument  evidencing an obligation  for borrowed  money,  or any
other  agreement or  instrument  to which it is a party or by which it or any of
its properties may be bound or affected.

          (vi) Neither the Company nor any  Subsidiaries  is in violation of any
provision of its respective  charter or Bylaws or in violation of any franchise,
license, permit, judgment, decree or order, or in violation of any statute, rule
or  regulation.  Neither  the  execution  and  delivery of this  Agreement,  the
Placement Agent's Warrant  Agreement,  the Warrant Agreement or the Subscription
Agreements,  nor the  issuance  and sale or delivery of the  Securities  nor the
consummation  of  any  of  the  transactions   contemplated  herein  or  in  the
Subscription Agreements,  the Warrant Agreement or the Placement Agent's Warrant
Agreement,  nor the  compliance  by the  Company  with the terms and  provisions
hereof or thereof, has conflicted with or will conflict with, or has resulted in
or will  result  in a breach  of,  any of the terms  and  provisions  of, or has
constituted  or will  constitute  a default  under,  or has  resulted in or will
result in the creation or imposition of any lien, charge or encumbrance upon any
property or assets of the Company or any of the  Subsidiaries or pursuant to the
terms of any indenture,  mortgage, deed of trust, note, loan or credit agreement
or any other  agreement or  instrument  evidencing  an  obligation  for borrowed
money,  or any other  agreement or instrument to which the Company or any of the
Subsidiaries  may be bound or to which  any of the  property  or  assets  of the
Company or any of the  Subsidiaries  is subject;  nor will such action result in
any violation of the provisions of the  respective  charter or the Bylaws of the
Company or any of the Subsidiaries, any statute or any order, rule or regulation
applicable  to the  Company of any court or of any  foreign,  federal,  state or
other regulatory authority or other government body having jurisdiction over the
Company or any of the Subsidiaries.

          Such counsel shall state that he has  participated in conferences with
other  officers  of  the  Company,   as  well  as  with  accountants  and  other
representatives  of the Company,  during which the contents of the  Subscription
Agreement  were  discussed.  Although such counsel is not passing upon, and does
not assume any responsibility for, the accuracy, completeness or fairness of any
statements  contained in the  Subscription  Agreement,  such counsel shall state
that,  on the  basis  of the  foregoing,  nothing  has  come to  such  counsel's
attention to lead him to believe that the Subscription Agreement, as of the date
thereof and the date of such opinion, contained or contains any untrue statement
of a  material  fact or omits to state a  material  fact  required  to be stated
therein  or  necessary  to make  the  statements  therein,  in the  light of the
circumstances  under  which  they were  made,  not  misleading  (except  for the
financial  statements,   notes  thereto  and  other  statistical  and  financial
information included therein or omitted therefrom, as to which such counsel need
express no opinion).

                                       13
<PAGE>

     C. At or prior to each Closing,  counsel for the Placement Agent shall have
been furnished such documents,  certificates and opinions as they may reasonably
require for the purpose of  enabling  them to review the matters  referred to in
this  Agreement  and the  Subscription  Agreement,  or in order to evidence  the
accuracy, completeness or satisfaction of any of the representations, warranties
or conditions herein contained.

     D. At and prior to each  Closing,  (i) there  shall  have been no  material
adverse change nor development  involving a prospective  change in the condition
or prospects or the business activities,  financial or otherwise, of the Company
or any of its  Subsidiaries  from the latest dates as of which such condition is
set  forth  in the  Subscription  Agreement;  (ii)  there  shall  have  been  no
transaction, not in the ordinary course of business, entered into by the Company
or any of its  Subsidiaries  which has not been  disclosed  in the  Subscription
Agreement;  (iii)  neither the Company nor any of the  Subsidiaries  shall be in
default  under any  provision  of any  instrument  relating  to any  outstanding
indebtedness  for which a waiver or extension has not been  otherwise  received;
(iv)  neither  the  Company  nor any of the  Subsidiaries  shall have issued any
securities  (other  than  those  set  forth in the  Subscription  Agreement)  or
declared or paid any dividend or made any  distribution  of its capital stock of
any class and there shall not have been any change in the indebtedness  (long or
short  term)  or  liabilities  or  obligations  of  the  Company  or  any of its
Subsidiaries  (contingent or otherwise)  except as disclosed in the Subscription
Agreement;  (v) no  material  amount of the assets of the  Company or any of its
Subsidiaries shall have been pledged or mortgaged;  and (vi) no action,  suit or
proceeding,  at law or in equity, against the Company or any of its Subsidiaries
or affecting any of their  respective  properties or businesses shall be pending
or threatened  before or by any court or federal or state  commission,  board or
other  administrative  agency,  domestic  or  foreign,  wherein  an  unfavorable
decision,  ruling or finding  could  materially  adversely  affect the business,
prospects  or  financial  condition  or  income  of  the  Company  or any of its
Subsidiaries.

     E. At each Closing,  the Placement  Agent shall have received a certificate
of the  Company  signed  by its chief  executive  officer  and  chief  financial
officer, dated as of the date of such Closing, to the effect that the conditions
set forth in subparagraph (C) above have been satisfied and that, as of the date
of such  Closing,  the  representations  and  warranties  of the Company and the
Subsidiaries set forth herein are true and correct.

     F. At each Closing,  the Company shall have duly executed and delivered the
appropriate amount and designation of certificates/instruments  representing the
Notes  and the  Warrants  to the  Placement  Agent as agent  for the  respective
holders thereof.

     G. At each  Closing,  the Company shall have duly executed and delivered to
the Placement Agent, or its designees, the Placement Agent Warrants in the names
and denominations specified by the Placement Agent.

9.   Termination.

     Either the Placement Agent or the Company may terminate the Offering in its
sole  discretion  prior  to  either  Closing.  In the  event  that  the  Company
determines to terminate the Offering from and after the date hereof  through the
end of the  Offering  Period for any reason  other  than the  Placement  Agent's
breach of the terms of this  Agreement,  and the  Placement  Agent is willing to
proceed,  then the Company  shall  immediately  pay to the  Placement  Agent the
amount of its out-of-pocket  expenses.  Upon such termination,  all Subscription
Agreements and payments for the Units not previously delivered to the purchasers
thereof,  without interest thereon or deduction therefrom,  shall be returned to
the respective subscribers, the Placement Agent shall have no further obligation
to the Company, and the Company shall have no obligation to the Placement Agent.
If the  Placement  Agent  does not or fails to  complete  the  Offering  and the
reasons  therefor are  reasonably  related to a material  adverse  change in the
business or financial  results,  prospects or condition of the Company,  factors
beyond  the  Placement  Agent's  control  and  through  no fault of its own or a
material adverse change in market conditions then, in any such case, the Company
agrees to promptly pay the Placement  Agent its actual  out-of-pocket  expenses,
including the fees and  disbursements of the Placement Agent's legal counsel and
shall remain  liable for all  reasonable  Blue Sky counsel fees and expenses and
Blue Sky filing fees.

10.  Miscellaneous.
