($6,500,000/March, 2003)

                             STOCK PURCHASE WARRANT

                        To Subscribe for Shares of Stock

                                       of

                                 TurboWorx, Inc.

         THIS CERTIFIES THAT, for value received, (the "holder"), is entitled to
subscribe for and purchase from  TurboWorx,  Inc. (the "Company") that number of
shares of the  Company's  equity  securities  described  herein  [as  defined in
Section 9(a), the "Stock"]  calculated in accordance  with Section 1 hereof at a
price per share calculated in accordance with Section 2 hereof (with adjustments
provided for herein,  the "Warrant  Price") at any time from the date determined
in accordance with Section 3 hereof to and including the earlier to occur of (i)
March 31, 2009;  and (ii) the date on which the Company  consummates  an initial
public  offering of its capital stock  registered  under the  Securities  Act of
1933,  as amended,  subject to the terms and  conditions  stated in this Warrant
(the "Warrant").

         This Warrant is one of a series of Stock Purchase  Warrants  ("Purchase
Warrants")  issued in conjunction  with a financing  commenced by the Company in
March 2003 consisting of convertible  notes issued by the Company  (collectively
the "Notes") of a maximum amount of $6,500,000.

         1.       NUMBER OF SHARES OF STOCK

         The  number  of  shares  of Stock the  holder  hereof  is  entitled  to
subscribe  for and purchase from the Company shall be determined by dividing the
principal  amount of the note $ with which this  Warrant  was issued by four (4)
and dividing the sum so arrived at by the Warrant

                                       1
<PAGE>

Price.

         2.       WARRANT PRICE

         The exercise price per share to be paid to the Company for the Stock to
which that holder  hereof has the right to subscribe  shall be determined by (i)
the purchase price per share of equity in the next round of financing  raised by
the  Company if such  equity is common  stock or debt  convertible  into  common
stock,  or the purchase price per share of equity in the next round of financing
raised by the Company if such equity is Preferred Stock or debt convertible into
or with a right to buy Preferred Stock attached, provided however in either case
a minimum of  $2,000,000 is raised (the  "Financing"),  or (ii) in the event the
Company  does not  close  the  Financing  by April 1,  2005,  $0.15 per share as
adjusted as provided herein.

         3.       EXERCISE OF WARRANT

         The rights  represented  by this Warrant may be exercised by the holder
after the earlier to occur of (i) the  closing by the Company of the  Financing,
or (ii) April 1, 2005,  in whole or in part by the surrender of this Warrant and
delivery  of an  executed  Exercise  Notice in the form  attached  hereto to the
Company at its principal office at any time or times within the period specified
above,  accompanied  by payment for the Stock so subscribed  for by certified or
bank check.  In the event of the partial  exercise of the rights  represented by
this Warrant,  a new Warrant  representing the number of shares as to which this
Warrant shall not have been exercised shall be promptly issued to the holder. In
any event,  such a new Warrant and a certificate or  certificates  for the Stock
purchased  shall be  delivered  by the  Company to the holder not later than ten
days after payment is made for the purchased Stock.

         4.       VALIDITY OF ISSUE

         The Company  warrants  and agrees that all shares of Stock which may be
issued upon the exercise of the rights  represented  by this Warrant will,  upon
issuance,  be fully paid and  nonassessable  and free from all taxes,  liens and
charges  with respect to the issue  thereof.  The Company  further  warrants and
agrees  that  during the period  within  which the  rights  represented  by this
Warrant may be  exercised,  the Company  will at all times have  authorized  and
reserved a  sufficient  number of shares of Stock to provide for the exercise of
the rights represented by this Warrant.

         5.       ADJUSTMENTS TO PREVENT DILUTION

         (a) If and whenever the Company shall issue or sell any shares of Stock
for a consideration per share less than the Warrant Price in effect  immediately
prior to the time of such  issue or sale,  then  upon  such  issue or sale,  the
Warrant Price shall be recalculated (and if applicable reduced,  but in no event
thereby  increased) to a price  (calculated  to the nearest cent)  determined by
dividing  (i) an amount  equal to the sum of (aa) the  number of shares of Stock
outstanding  immediately  prior  to such  issue or sale  multiplied  by the then
existing  Warrant Price,  and (bb) the  consideration,  if any,  received by the
Company  upon  such  issue or sale by (ii) the  total  number of shares of Stock
outstanding immediately after such issue or sale.

                                       2
<PAGE>

                  (1) If at any time the Company  shall in any manner  grant any
options  or  rights  to  subscribe  for  or  to  purchase  Stock  or  securities
convertible  into Stock  ("Convertible  Securities")  or shall issue or sell any
Convertible  Securities and the price per share for which Stock is issuable upon
the  exercise of such rights or options or upon  conversion  or exchange of such
Convertible  Securities  [determined  by dividing (i) the total amount,  if any,
received or receivable by the Company as consideration  for the granting of such
rights or options or for the issuance or sale of  Convertible  Securities,  plus
the minimum aggregate amount of additional  consideration payable to the Company
upon  the  exercise  of  such  rights  or  options,  plus,  in the  case of such
Convertible   Securities,   the   minimum   aggregate   amount   of   additional
consideration,  if any, payable upon the conversion or exchange thereof, by (ii)
the total maximum  number of shares of Stock  issuable upon the exercise of such
rights  or  options  or upon the  conversion  or  exchange  of such  Convertible
Securities] shall be less than the Warrant Price in effect  immediately prior to
the time of the  granting of such  rights or options or the  issuance or sale of
such  Convertible  Securities,  then the total maximum number of shares of Stock
issuable  upon the  exercise  of such  rights or options or upon  conversion  or
exchange  of such  Convertible  Securities  shall (as of the date of granting of
such rights or options or the issuance or sale of such  Convertible  Securities)
be deemed to be outstanding and to have been issued for such price per share. No
further  adjustments of the Warrant Price shall be made upon the actual issue of
such Stock or of such  Convertible  Securities  upon  exercise of such rights or
options or upon the actual  issue of such Stock upon  conversion  or exchange of
such Convertible  Securities.  Unless a provision of any other paragraph of this
Section 4  controls,  if the price per share for which  Stock is  issuable  upon
exercise  of such  rights or  options or upon  conversion  or  exchange  of such
Convertible  Securities  shall  change at any time,  the  Warrant  Price then in
effect shall  forthwith be adjusted or readjusted to such Warrant Price as would
have obtained had the adjustments made upon the issuance or sale of such rights,
options or Convertible  Securities  been made upon the basis of (a) the issuance
of the number of shares of Stock theretofore  actually  delivered (and the total
consideration  received therefor) upon the exercise of such options or rights or
upon the  conversion  or exchange of such  Convertible  Securities,  and (b) the
assumption  that the  remaining  outstanding  options,  rights,  or  Convertible
Securities were originally  issued at the time of such change. On the expiration
of any such option or right or the  termination  of any such right to convert or
exchange  such  Convertible  Securities,  the Warrant Price then in effect shall
forthwith be  readjusted  to such Warrant  Price as would have  obtained had the
adjustments  made  upon  the  issuance  or sale of such  rights  or  options  or
Convertible  Securities  been  made upon the  basis of (a) the  issuance  of the
number  of  shares  of Stock  theretofore  actually  delivered  (and  the  total
consideration  received therefor) upon the exercise of such rights or options or
upon the  conversion  or exchange  of such  Convertible  Securities  and (b) the
issuance or sale of any such options, rights or Convertible Securities as remain
outstanding after said expiration or termination.

                  (2) If the  Company  shall  declare  a  dividend,  or make any
further distribution upon any capital stock of the Company,  payable in Stock or
Convertible  Securities,  then any Stock or Convertible  Securities (as the case
may be) issuable in payment of such dividend or distribution  shall be deemed to
have  been  issued  or  sold  without  consideration;  and  in  addition  to the
adjustment  of the Warrant Price  required by this Section  4(a),  the number of
shares of Stock issuable upon exercise of this Warrant shall be  proportionately
increased so that the holder upon

                                       3
<PAGE>

exercise of this Warrant  shall be entitled to receive the same number of shares
of Stock which it would have received if it had  exercised  this Warrant in full
immediately prior to the date for determining  stockholders  entitled to receive
such dividend or distribution.

                  (3) If any shares of Stock or  Convertible  Securities  or any
rights or options to purchase any such Stock or Convertible  Securities shall be
issued  for  cash,  then the  consideration  received  shall be deemed to be the
amount  received by the  Company,  without  deduction  therefrom of any expenses
incurred or any  underwriting  commissions or concessions paid or allowed by the
Company in  connection  therewith.  In case any  shares of Stock or  Convertible
Securities  or any rights or options to purchase  any such Stock or  Convertible
Securities  shall be issued for a  consideration  other than cash, the amount of
the consideration  other than cash received by the Company shall be deemed to be
the value of such  consideration  as determined by the Board of Directors of the
Company,  without  deduction  of  any  expenses  incurred  or  any  underwriting
commissions  or  concessions  paid  or  allowed  by the  Company  in  connection
therewith.

                  (4) If the  Company  shall take a record of the holders of its
Stock for the  purpose of  entitling  them (i) to  receive a  dividend  or other
distribution payable in Stock or in Convertible Securities, or (ii) to subscribe
for or  purchase  Stock or  Convertible  Securities,  then for  purposes of this
Warrant  such record date shall be deemed to be the date of the issue or sale of
the shares of Stock deemed to have been issued or sold upon the  declaration  of
such  dividend  or the  making  of such  other  distribution  or the date of the
granting of such right of subscription or purchase, as the case may be.

         (b) If the  Company  shall  declare  a  dividend  upon any Stock of the
Company payable  otherwise than as a cash dividend paid out of current earnings,
or in  Stock  or  Convertible  Securities,  then the  Warrant  Price  in  effect
immediately  prior to the  declaration  of such dividend  shall be reduced by an
amount  equal  to the  fair  value  of  the  dividend  per  share  of the  Stock
outstanding  at the  time of such  declaration  as  determined  by the  Board of
Directors of the  Company.  Such  reduction  shall take effect as of the date on
which a record is taken for the purpose of such  dividend or, if a record is not
taken,  the date as of which the  holders  of Stock of record  entitled  to such
dividend are to be determined.

         (c) If the Company shall at any time subdivide its  outstanding  shares
of Stock  into a greater  number of  shares,  then the  Warrant  Price in effect
immediately prior to such subdivision shall be proportionately  reduced, and the
number of shares issuable upon exercise of this Warrant shall be proportionately
increased;  and  conversely,  in case  the  outstanding  shares  of Stock of the
Company shall be combined into a smaller number of shares,  the Warrant Price in
effect immediately prior to such combination shall be proportionately  increased
and the number of shares issuable proportionately reduced.

         (d) Except as provided in paragraph (c) of this Section, if any capital
reorganization  or  reclassification  of the capital  stock of the  Company,  or
consolidation or merger of the Company with another corporation,  or the sale of
all or  substantially  all  of its  assets  or of  any  successor  corporation's
property  and  assets  to  any  other  corporation  or  corporations  (any  such
corporation   being  included   within  the  meaning  of  the  term   "successor
corporation") shall be

                                       4
<PAGE>

effected,  then  as a  condition  of  such  recapitalization,  reclassification,
consolidation,  merger,  or conveyance,  lawful and adequate  provision shall be
made whereby the holder shall  thereafter have the right to purchase and receive
upon the basis and upon the terms and  conditions  specified in this Warrant and
in  lieu  of  the  shares  of  Stock  of  the  Company  immediately  theretofore
purchasable  and receivable upon the exercise of the right  represented  hereby,
such  shares of stock,  securities  or assets as may be issued or  payable  with
respect to or in exchange for a number of outstanding shares of such Stock equal
to the number of shares of such Stock  immediately  theretofore  purchasable and
receivable  upon  the  exercise  of  the  rights  represented  hereby  had  such
recapitalization,  reclassification,  consolidation,  merger or  conveyance  not
taken  place,  and in any such case  appropriate  provisions  shall be made with
respect  to the rights and  interests  of the holder of this  Warrant to the end
that  the  provisions  hereof  (including  without  limitation   provisions  for
adjustment of the warrant price and of the number of shares purchasable upon the
exercise of this warrant) shall  thereafter be applicable,  as nearly as may be,
in relation to any shares of stock,  securities or assets thereafter deliverable
upon the exercise hereof. Except as hereinafter provided,  the Company shall not
effect any consolidation or merger unless prior to the consummation  thereof the
successor  corporation shall assume by written instrument executed and mailed to
the holder at its address  registered on the books of the Company the obligation
to deliver  to the  holder  such  shares of stock,  securities  or assets as, in
accordance  with the  foregoing  provisions,  such  holder  may be  entitled  to
purchase.   Notwithstanding  the  foregoing,   in  the  event  of  a  merger  or
consolidation in which the Company is not the surviving  entity,  if the Company
concludes  that it will be unable to satisfy the  conditions  of this  paragraph
without a material  adverse  effect on the terms of such  proposed  transaction,
then the Company shall have the option, prior to or  contemporaneously  with the
closing of such merger or consolidation, to purchase the Warrant from the holder
at its then fair  value,  having  regard to both the spread  between the Warrant
Price and the value of the  consideration  to be received in the transaction and
the remaining term of the Warrant. In the event that stock,  securities or other
assets  are  issuable  or  payable  as  consideration  in  any  such  merger  or
consolidation, then such fair value shall be paid with such stock, securities or
other assets. The Company and the holder of the Warrant shall agree on such fair
value or, in the event they are unable to agree,  shall  submit the  question of
fair value to binding arbitration before a single arbitrator sitting in Shelton,
Connecticut,  under the commercial rules of the American Arbitration Association
(any cost of arbitration to be borne by the Company).

         (e) Upon any  adjustment  of the Warrant  Price,  then and in each such
case the Company shall give written notice thereof, by first class mail, postage
prepaid,  addressed to the holder of this Warrant at its address  registered  on
the books of the Company,  which notice shall state the Warrant Price  resulting
from such  adjustment and the increased or decreased,  if any,  number of shares
purchasable  at such price upon the exercise of this  Warrant,  setting forth in
reasonable  detail  the  method of  calculation  and the facts  upon  which such
calculation is based.

         (f) This Section 5 shall not apply to the issuance of Stock, or options
therefor,  (i) in connection  with the Financing,  (ii) to officers or employees
of, or consultants  to, the Company  pursuant either to the Company's 2000 Stock
Plan,  including  amendments thereto, or to future stock plans of like kind, all
such  amendments or plans as approved by a majority of the Board of Directors of
the Company and subject to an aggregate cap of 3,500,000  shares as adjusted for

                                       5
<PAGE>

splits, combinations, and reclassifications,  and (iii) to officers or employees
of,  or  consultants  to,  the  Company  pursuant  to any  agreements  for Stock
heretofore granted by the Company.

         6.       NOTICE OF REORGANIZATIONS, ETC.

         In case at any time:

         (a) there shall be any capital  reorganization,  or reclassification of
the capital stock of the Company, or consolidation or merger of the Company with
another corporation; or

         (b) there shall be a voluntary or involuntary dissolution,  liquidation
or winding  up of the  Company;  then,  in each one or more of said  cases,  the
Company  shall give at least the same  notice as is  provided  to the  Company's
shareholders,  by first class mail, postage prepaid,  addressed to the holder at
its address  registered on the books of the Company of (i) the date on which the
books of the  Company  shall  close or a record  shall be taken for  purposes of
ascertaining   which   shareholders   will   be   entitled   to   vote  on  such
reclassification,    reorganization,    consolidation,    merger,   dissolution,
liquidation  or winding  up, as the case may be; (ii) the date on which the vote
shall be taken concerning such reclassification,  reorganization, consolidation,
merger,  dissolution,  liquidation  or winding up, as the case may be; and (iii)
the date on which such reclassification,  liquidation or winding up, as the case
may be, is to be effective.  Such notice shall also specify the date as of which
the holders of Stock of record  shall be  entitled  to exchange  their Stock for
securities   or   other   property   deliverable   upon   such   reorganization,
reclassification,  consolidation,  merger, dissolution,  liquidation, or winding
up, as the case may be.

         7.       ISSUANCE OF ADDITIONAL STOCK

         The  Company  shall give to the  holder at least the same  notice as is
provided to the Company's  shareholders,  by first class mail,  postage prepaid,
addressed to the holder at its address  registered  on the books of the Company,
of the record  date for  determining  the  holders of Stock who shall be granted
rights  as a class to  subscribe  for or to  purchase,  or any  options  for the
purchase of,  Stock or  Convertible  Securities,  to the end that the holder may
exercise  its rights to acquire  Stock  under this  Warrant,  by  delivery of an
executed Exercise Notice in accordance with Section 3 prior to said record date,
and may thereby receive the same rights as other holders of Stock on said record
date.

         8.       INVESTMENT REPRESENTATION

         The holder by  accepting  this Warrant  represents  that the Warrant is
acquired  for the holder's  own account for  investment  purposes and not with a
view to any  offering  or  distribution  and  that  the  holder  has no  present
intention  of selling or otherwise  disposing  of the Warrant or the  underlying
shares of  Stock.  Upon  exercise,  the  holder  will  confirm,  in  respect  of
securities obtained upon such exercise, that it is acquiring such securities for
its own account and not with a view to any offering or distribution in violation
of applicable securities laws.

                                       6
<PAGE>

         9.       MISCELLANEOUS

         (a) As used herein the term "Stock"  shall mean (i) if the Financing is
consummated  on or before April 1, 2005, the type of equity  securities  sold in
the Financing; or (ii) if the Financing is not consummated on or before April 1,
2005, the Company's  presently  authorized  Common Stock,  $.001 par value,  and
stock of any  other  class  into  which  such  presently  authorized  Stock  may
hereafter be changed.  For the  purposes of Sections 5, the term  "Stock"  shall
also include any capital stock of any class of the Company hereafter  authorized
which shall not be limited to a fixed sum or percentage in respect of the rights
of the holders  thereof to  participate in dividends or in the  distribution  of
assets upon the voluntary or involuntary liquidation,  dissolution or winding up
of the Company.

         (b) This Warrant  shall not entitle the holder to any voting  rights or
other rights as a stockholder of the Company,  or to any other rights whatsoever
except the rights herein expressed, and no cash dividend paid out of earnings or
surplus or interest shall be payable or accrue in respect of this Warrant or the
interest  represented  hereby  or the  shares  which may be  subscribed  for any
purchased  hereunder  until and unless and except to the extent  that the rights
represented by this Warrant shall be exercised.

         (c) This  Warrant is  exchangeable,  upon the  surrender  hereof at the
office or agency of the Company,  for new Warrants of like tenor representing in
the aggregate the right to subscribe for and purchase the number of shares which
may be  subscribed  for and  purchased  hereunder,  each of such new Warrants to
represent the right to subscribe for and purchase each number of shares as shall
be designated by said holder at the time of such surrender.

         (d) The Purchase Warrants and any terms thereof may be changed, waived,
discharged or terminated  only by an instrument in writing signed by the holders
of 50.1% of the Stock  issuable  upon  exercise of the Purchase  Warrants.  This
Warrant shall be construed  and enforced in accordance  with and governed by the
internal  laws of the State of  Connecticut.  The  descriptive  headings  of the
several  sections and  paragraphs  in this Warrant are for purposes of reference
only,  and shall not limit or  otherwise  affect  any of the terms  hereof.  The
invalidity or  unenforceability  of any provision  hereof shall in no way affect
the validity or enforceability of any other provision.

         (e)  Fractional  shares  shall not be issued upon the  exercise of this
Warrant,  but in any case where the holder would,  except for the  provisions of
this Section  9(e),  be entitled  under the terms hereof to receive a fractional
share upon the complete  exercise of this Warrant,  the Company shall,  upon the
exercise of this Warrant for the largest number of whole shares then called for,
cancel this Warrant and pay a sum in cash equal to the value of such  fractional
share  (determined in such reasonable  manner as may be prescribed in good faith
by the Board of Directors of the Company).

         (f) If this  Warrant  is lost,  stolen,  mutilated  or  destroyed,  the
Company  may,  on such  terms  as to  indemnity  or  otherwise  as it may in its
discretion impose (which shall, in the case of a mutilated Warrant,  include the
surrender  thereof),  issue a new Warrant of like  denomination and tenor as the
Warrant so lost,  stolen,  mutilated or  destroyed.  Any such new Warrant  shall

                                       7
<PAGE>

constitute an original contractual obligation of the Company, whether or not the
allegedly  lost,  stolen,  mutilated or destroyed  Warrant  shall be at any time
enforceable by anyone.

         10.      TRANSFER AND REGISTRATION

         (a) If any proposed  transfer,  in whole or in part, of this Warrant or
the Stock  issuable  upon exercise of this Warrant  might  reasonably  involve a
public  offering  of the same  contrary  to the  investment  representations  in
Section 8, the Company may require,  as a condition  precedent to such transfer,
an opinion of counsel,  satisfactory to it, that the proposed  transfer will not
involve  a  public  offering  which  is  required  to be  registered  under  the
Securities Act of 1933.  However,  no such  requirement  shall be imposed during
such time as a new registration statement or a post-effective  amendment thereof
covering the Stock or part thereof being  transferred  is in effect.  Subject to
the foregoing,  this Warrant and all rights hereunder is transferable,  in whole
or in part, on the books of the Company to be maintained for such purpose,  upon
surrender of this Warrant at the principal office of the Company,  together with
a written assignment of this Warrant duly executed by the holder or its agent or
attorney.

         (b) This  Warrant  and the name and  address  of the  holder  have been
registered in a Warrant  Register  that is kept at the  principal  office of the
Company,  and the Company  may treat the holder so  registered  as the  absolute
owner of this Warrant for all purposes.

Warrant No. TWC-BRIDGE-000

                             STOCK PURCHASE WARRANT

                     To Subscribe for Shares of Common Stock

                                       of

                                 TurboWorx, Inc.

         THIS CERTIFIES THAT, for value received, _________________________ (the
"Holder"),  is entitled to subscribe for and purchase from TurboWorx,  Inc. (the
"Company") up to _______ shares (the "Warrant  Shares") of the Company's  Common
Stock,  $.001 par  value,  (the  "Stock")  at a price  per  share of $2.50  (the
"Warrant  Price") at any time from the date hereof to and  including the earlier
to occur of (i)  March  31,  2009;  and  (ii)  the  date on  which  the  Company
consummates an initial public offering of its capital stock registered under the
Securities Act of 1933, as amended,  subject to the terms and conditions  stated
in this Warrant  (the  "Warrant").  The Warrant  Price and the number of Warrant
Shares for which the Warrant is  exercisable  shall be subject to  adjustment as
provided herein.

         This  Warrant  is one of a  series  of  Stock  Purchase  Warrants  (the
"Purchase  Warrants") issued in connection with certain  promissory notes issued
by the Company during 2003 and 2004 (the "Trautman Wasserman Bridge Notes").

         1.       EXERCISE OF WARRANT

         The rights  represented  by this Warrant may be exercised by the Holder
in whole or in part by the surrender of this Warrant and delivery of an executed
Exercise  Notice in the form  attached  hereto to the  Company at its  principal
office at any time or times within the period  specified  above,  accompanied by
payment for the Stock so subscribed for by certified or bank check. In the event
of the partial exercise of the rights represented by this Warrant, a new Warrant

                                       1
<PAGE>

representing  the number of shares as to which this Warrant  shall not have been
exercised shall be promptly issued to the Holder. In any event, such new Warrant
and a certificate or certificates  for the Stock purchased shall be delivered by
the Company to the Holder not later than ten days after  payment is made for the
purchased Stock.

         2.       VALIDITY OF ISSUE

         The Company  warrants  and agrees that all shares of Stock which may be
issued upon the exercise of the rights  represented  by this Warrant will,  upon
issuance,  be fully paid and  nonassessable  and free from all taxes,  liens and
charges  with respect to the issue  thereof.  The Company  further  warrants and
agrees  that  during the period  within  which the  rights  represented  by this
Warrant may be  exercised,  the Company  will at all times have  authorized  and
reserved a  sufficient  number of shares of Stock to provide for the exercise of
the rights represented by this Warrant.

         3.       ADJUSTMENTS TO PREVENT DILUTION

         (a) If and whenever the Company shall issue or sell any shares of Stock
for a consideration per share less than the Warrant Price in effect  immediately
prior to the time of such  issue or sale,  then  upon  such  issue or sale,  the
Warrant Price shall be recalculated (and if applicable reduced,  but in no event
thereby  increased) to a price  (calculated  to the nearest cent)  determined by
dividing  (i) an amount  equal to the sum of (aa) the  number of shares of Stock
outstanding  immediately  prior  to such  issue or sale  multiplied  by the then
existing  Warrant Price,  and (bb) the  consideration,  if any,  received by the
Company  upon  such  issue or sale by (ii) the  total  number of shares of Stock
outstanding immediately after such issue or sale.

                  (1) If at any time the Company  shall in any manner  grant any
options  or  rights  to  subscribe  for  or  to  purchase  Stock  or  securities
convertible  into Stock  ("Convertible  Securities")  or shall issue or sell any
Convertible  Securities and the price per share for which Stock is issuable upon
the  exercise of such rights or options or upon  conversion  or exchange of such
Convertible  Securities  [determined  by dividing (i) the total amount,  if any,
received or receivable by the Company as consideration  for the granting of such
rights or options or for the issuance or sale of  Convertible  Securities,  plus
the minimum aggregate amount of additional  consideration payable to the Company
upon  the  exercise  of  such  rights  or  options,  plus,  in the  case of such
Convertible   Securities,   the   minimum   aggregate   amount   of   additional
consideration,  if any, payable upon the conversion or exchange thereof, by (ii)
the total maximum  number of shares of Stock  issuable upon the exercise of such
rights  or  options  or upon the  conversion  or  exchange  of such  Convertible
Securities] shall be less than the Warrant Price in effect  immediately prior to
the time of the  granting of such  rights or options or the  issuance or sale of
such  Convertible  Securities,  then the total maximum number of shares of Stock
issuable  upon the  exercise  of such  rights or options or upon  conversion  or
exchange  of such  Convertible  Securities  shall (as of the date of granting of
such rights or options or the issuance or sale of such  Convertible  Securities)
be deemed to be outstanding and to have been issued for such price per share. No
further  adjustments of the Warrant Price shall be made upon the actual issue of
such Stock or of such  Convertible  Securities  upon  exercise of such rights or
options or upon the actual  issue of such Stock upon  conversion  or exchange of
such Convertible  Securities.  Unless a

                                       2
<PAGE>

provision of any other  paragraph  of this Section 3 controls,  if the price per
share for which  Stock is  issuable  upon  exercise of such rights or options or
upon conversion or exchange of such  Convertible  Securities shall change at any
time, the Warrant Price then in effect shall forthwith be adjusted or readjusted
to such Warrant Price as would have obtained had the  adjustments  made upon the
issuance or sale of such rights,  options or  Convertible  Securities  been made
upon the basis of (a) the issuance of the number of shares of Stock  theretofore
actually  delivered  (and the total  consideration  received  therefor) upon the
exercise of such  options or rights or upon the  conversion  or exchange of such
Convertible  Securities,  and (b) the assumption that the remaining  outstanding
options, rights, or Convertible Securities were originally issued at the time of
such change. On the expiration of any such option or right or the termination of
any such right to convert or exchange such Convertible  Securities,  the Warrant
Price then in effect shall  forthwith  be  readjusted  to such Warrant  Price as
would have obtained had the  adjustments  made upon the issuance or sale of such
rights or options or Convertible  Securities been made upon the basis of (a) the
issuance of the number of shares of Stock  theretofore  actually  delivered (and
the total  consideration  received therefor) upon the exercise of such rights or
options or upon the  conversion or exchange of such  Convertible  Securities and
(b) the issuance or sale of any such options,  rights or Convertible  Securities
as remain outstanding after said expiration or termination.

                  (2) If the  Company  shall  declare  a  dividend,  or make any
further distribution upon any capital stock of the Company,  payable in Stock or
Convertible  Securities,  then any Stock or Convertible  Securities (as the case
may be) issuable in payment of such dividend or distribution  shall be deemed to
have  been  issued  or  sold  without  consideration;  and  in  addition  to the
adjustment  of the Warrant Price  required by this Section  3(a),  the number of
shares of Stock issuable upon exercise of this Warrant shall be  proportionately
increased so that the Holder upon  exercise of this Warrant shall be entitled to
receive the same  number of shares of Stock  which it would have  received if it
had exercised this Warrant in full immediately prior to the date for determining
stockholders entitled to receive such dividend or distribution.

                  (3) If any shares of Stock or  Convertible  Securities  or any
rights or options to purchase any such Stock or Convertible  Securities shall be
issued  for  cash,  then the  consideration  received  shall be deemed to be the
amount  received by the  Company,  without  deduction  therefrom of any expenses
incurred or any  underwriting  commissions or concessions paid or allowed by the
Company in  connection  therewith.  In case any  shares of Stock or  Convertible
Securities  or any rights or options to purchase  any such Stock or  Convertible
Securities  shall be issued for a  consideration  other than cash, the amount of
the consideration  other than cash received by the Company shall be deemed to be
the value of such  consideration  as determined by the Board of Directors of the
Company,  without  deduction  of  any  expenses  incurred  or  any  underwriting
commissions  or  concessions  paid  or  allowed  by the  Company  in  connection
therewith.

                  (4) If the  Company  shall take a record of the holders of its
Stock for the  purpose of  entitling  them (i) to  receive a  dividend  or other
distribution payable in Stock or in Convertible Securities, or (ii) to subscribe
for or  purchase  Stock or  Convertible  Securities,  then for  purposes of this
Warrant  such record date shall be deemed to be the date of the issue or sale of
the shares of Stock deemed to have been issued or sold upon the  declaration  of
such  dividend

                                       3
<PAGE>

or the making of such other  distribution  or the date of the  granting  of such
right of subscription or purchase, as the case may be.

         (b) If the  Company  shall  declare  a  dividend  upon any Stock of the
Company payable  otherwise than as a cash dividend paid out of current earnings,
or in  Stock  or  Convertible  Securities,  then the  Warrant  Price  in  effect
immediately  prior to the  declaration  of such dividend  shall be reduced by an
amount  equal  to the  fair  value  of  the  dividend  per  share  of the  Stock
outstanding  at the  time of such  declaration  as  determined  by the  Board of
Directors of the  Company.  Such  reduction  shall take effect as of the date on
which a record is taken for the purpose of such  dividend or, if a record is not
taken,  the date as of which the  holders  of Stock of record  entitled  to such
dividend are to be determined.

         (c) If the Company shall at any time subdivide its  outstanding  shares
of Stock  into a greater  number of  shares,  then the  Warrant  Price in effect
immediately prior to such subdivision shall be proportionately  reduced, and the
number of shares issuable upon exercise of this Warrant shall be proportionately
increased;  and  conversely,  in case  the  outstanding  shares  of Stock of the
Company shall be combined into a smaller number of shares,  the Warrant Price in
effect immediately prior to such combination shall be proportionately  increased
and the number of shares issuable proportionately reduced.

         (d)  Except as  provided  in  paragraph  (c) of this  Section 3, if any
capital  reorganization or reclassification of the capital stock of the Company,
or consolidation or merger of the Company with another corporation,  or the sale
of all or  substantially  all of its  assets or of any  successor  corporation's
property  and  assets  to  any  other  corporation  or  corporations  (any  such
corporation   being  included   within  the  meaning  of  the  term   "successor
corporation") shall be effected,  then as a condition of such  recapitalization,
reclassification,  consolidation,  merger,  or  conveyance,  lawful and adequate
provision  shall be made whereby the Holder shall  thereafter  have the right to
purchase and receive upon the basis and upon the terms and conditions  specified
in this  Warrant and in lieu of the shares of Stock of the  Company  immediately
theretofore   purchasable   and  receivable  upon  the  exercise  of  the  right
represented hereby, such shares of stock,  securities or assets as may be issued
or payable with respect to or in exchange for a number of outstanding  shares of
such Stock equal to the number of shares of such Stock  immediately  theretofore
purchasable  and receivable upon the exercise of the rights  represented  hereby
had such recapitalization, reclassification, consolidation, merger or conveyance
not taken place, and in any such case appropriate  provisions shall be made with
respect  to the rights and  interests  of the Holder of this  Warrant to the end
that  the  provisions  hereof  (including  without  limitation   provisions  for
adjustment of the warrant price and of the number of shares purchasable upon the
exercise of this warrant) shall  thereafter be applicable,  as nearly as may be,
in relation to any shares of stock,  securities or assets thereafter deliverable
upon the exercise hereof. Except as hereinafter provided,  the Company shall not
effect any consolidation or merger unless prior to the consummation  thereof the
successor  corporation shall assume by written instrument executed and mailed to
the Holder at its address  registered on the books of the Company the obligation
to deliver  to the  Holder  such  shares of stock,  securities  or assets as, in
accordance  with the  foregoing  provisions,  such  Holder  may be  entitled  to
purchase.   Notwithstanding  the  foregoing,   in  the  event  of  a  merger  or
consolidation in which the Company is not the surviving  entity,  if the Company
concludes  that it will be unable to satisfy the  conditions  of this  paragraph
without a

                                       4
<PAGE>

material  adverse  effect on the terms of such  proposed  transaction,  then the
Company shall have the option, prior to or contemporaneously with the closing of
such merger or  consolidation,  to purchase  the Warrant  from the Holder at its
then fair value,  having regard to both the spread between the Warrant Price and
the  value  of the  consideration  to be  received  in the  transaction  and the
remaining  term of the Warrant.  The Company and the Holder of the Warrant shall
agree on such fair value or, in the event they are unable to agree, shall submit
the  question of fair value to binding  arbitration  before a single  arbitrator
sitting in Shelton,  Connecticut,  under the  commercial  rules of the  American
Arbitration Association (any cost of arbitration to be borne by the Company).

         (e) Upon any  adjustment  of the Warrant  Price,  then and in each such
case the Company shall give written notice thereof, by first class mail, postage
prepaid,  addressed to the Holder of this Warrant at its address  registered  on
the books of the Company,  which notice shall state the Warrant Price  resulting
from such  adjustment and the increased or decreased,  if any,  number of shares
purchasable  at such price upon the exercise of this  Warrant,  setting forth in
reasonable  detail  the  method of  calculation  and the facts  upon  which such
calculation is based.

         (f)  Upon  each  adjustment  of  the  Warrant  Price  pursuant  to  the
provisions  of this Section 3, the number of Warrant  Shares  issuable  upon the
exercise  of this  Warrant  shall  be  adjusted  to the  nearest  full  Share by
multiplying a number equal to the Warrant Price in effect  immediately  prior to
such  adjustment by the number of Warrant Shares  issuable upon exercise of this
Warrant  immediately  prior to such  adjustment  and  dividing  the  product  so
obtained by the adjusted Warrant Price.

         (g) This Section 3 shall not apply to the issuance of Stock, or options
therefor, (i) in connection with the Private Offering described in the Company's
Private  Placement  Memorandum  dated  December  7, 2004;  (ii) to  officers  or
employees of, or consultants  to, the Company  pursuant  either to the Company's
2000 Stock Plan,  including amendments thereto, or to future stock plans of like
kind,  all such  amendments  or plans as  approved by a majority of the Board of
Directors of the Company;  and (iii) to officers or employees of, or consultants
to, the Company pursuant to any agreements for Stock  heretofore  granted by the
Company.

         4.       NOTICE OF REORGANIZATIONS, ETC.

         In case at any time:

         (a) there shall be any capital  reorganization,  or reclassification of
the capital stock of the Company, or consolidation or merger of the Company with
another corporation; or

         (b) there shall be a voluntary or involuntary dissolution,  liquidation
or winding  up of the  Company;  then,  in each one or more of said  cases,  the
Company  shall give at least the same  notice as is  provided  to the  Company's
shareholders,  by first class mail, postage prepaid,  addressed to the Holder at
its address  registered on the books of the Company of (i) the date on which the
books of the  Company  shall  close or a record  shall be taken for  purposes of
ascertaining   which   shareholders   will   be   entitled   to   vote  on  such
reclassification,    reorganization,    consolidation,    merger,   dissolution,
liquidation  or winding  up, as the case may be; (ii) the date on

                                       5
<PAGE>

which the vote shall be taken concerning such reclassification,  reorganization,
consolidation,  merger, dissolution,  liquidation or winding up, as the case may
be; and (iii) the date on which such  reclassification,  liquidation  or winding
up, as the case may be, is to be  effective.  Such notice shall also specify the
date as of which the  holders of Stock of record  shall be  entitled to exchange
their  Stock  for   securities   or  other   property   deliverable   upon  such
reorganization,    reclassification,    consolidation,    merger,   dissolution,
liquidation, or winding up, as the case may be.

         5.       ISSUANCE OF ADDITIONAL STOCK

         The  Company  shall give to the  Holder at least the same  notice as is
provided to the Company's  shareholders,  by first class mail,  postage prepaid,
addressed to the Holder at its address  registered  on the books of the Company,
of the record  date for  determining  the  holders of Stock who shall be granted
rights  as a class to  subscribe  for or to  purchase,  or any  options  for the
purchase of,  Stock or  Convertible  Securities,  to the end that the Holder may
exercise  its rights to acquire  Stock  under this  Warrant,  by  delivery of an
executed Exercise Notice in accordance with Section 1 prior to said record date,
and may thereby receive the same rights as other holders of Stock on said record
date.

         6.       INVESTMENT REPRESENTATION

         The Holder by  accepting  this Warrant  represents  that the Warrant is
acquired  for the Holder's  own account for  investment  purposes and not with a
view to any  offering  or  distribution  and  that  the  Holder  has no  present
intention  of selling or otherwise  disposing  of the Warrant or the  underlying
shares of  Stock.  Upon  exercise,  the  Holder  will  confirm,  in  respect  of
securities obtained upon such exercise, that it is acquiring such securities for
its own account and not with a view to any offering or distribution in violation
of applicable securities laws.

         7.       MISCELLANEOUS

         (a) For the purposes of Section 3, the term "Stock"  shall also include
any capital stock of any class of the Company  hereafter  authorized which shall
not be  limited  to a fixed sum or  percentage  in  respect of the rights of the
holders  thereof to  participate in dividends or in the  distribution  of assets
upon the voluntary or involuntary liquidation,  dissolution or winding up of the
Company.

         (b) This Warrant  shall not entitle the Holder to any voting  rights or
other rights as a stockholder of the Company,  or to any other rights whatsoever
except the rights herein expressed, and no cash dividend paid out of earnings or
surplus or interest shall be payable or accrue in respect of this Warrant or the
interest  represented  hereby  or the  shares  which may be  subscribed  for any
purchased  hereunder  until and unless and except to the extent  that the rights
represented by this Warrant shall be exercised.

         (c) This  Warrant is  exchangeable,  upon the  surrender  hereof at the
office or agency of the Company,  for new Warrants of like tenor representing in
the aggregate the right to subscribe for and purchase the number of shares which
may be  subscribed  for and  purchased  hereunder,

                                       6
<PAGE>

each of such new Warrants to represent  the right to subscribe  for and purchase
each number of shares as shall be  designated by said Holder at the time of such
surrender.

         (d) The Purchase Warrants and any terms thereof may be changed, waived,
discharged or terminated  only by an instrument in writing signed by the Holders
of 50.1% of the Stock  issuable  upon  exercise of the Purchase  Warrants.  This
Warrant shall be construed  and enforced in accordance  with and governed by the
internal  laws of the State of  Connecticut.  The  descriptive  headings  of the
several  sections and  paragraphs  in this Warrant are for purposes of reference
only,  and shall not limit or  otherwise  affect  any of the terms  hereof.  The
invalidity or  unenforceability  of any provision  hereof shall in no way affect
the validity or enforceability of any other provision.

         (e)  Fractional  shares  shall not be issued upon the  exercise of this
Warrant,  but in any case where the Holder would,  except for the  provisions of
this Section  7(e),  be entitled  under the terms hereof to receive a fractional
share upon the complete  exercise of this Warrant,  the Company shall,  upon the
exercise of this Warrant for the largest number of whole shares then called for,
cancel this Warrant and pay a sum in cash equal to the value of such  fractional
share  (determined in such reasonable  manner as may be prescribed in good faith
by the Board of Directors of the Company).

         (f) If this  Warrant  is lost,  stolen,  mutilated  or  destroyed,  the
Company  may,  on such  terms  as to  indemnity  or  otherwise  as it may in its
discretion impose (which shall, in the case of a mutilated Warrant,  include the
surrender  thereof),  issue a new Warrant of like  denomination and tenor as the
Warrant so lost,  stolen,  mutilated or  destroyed.  Any such new Warrant  shall
constitute an original contractual obligation of the Company, whether or not the
allegedly  lost,  stolen,  mutilated or destroyed  Warrant  shall be at any time
enforceable by anyone.

         (g) As of the date  hereof,  the  principal  office of the  Company  is
located at 3 Enterprise Drive, Suite 401, Shelton, Connecticut 06484.

         8.       TRANSFER AND REGISTRATION

         (a) If any proposed  transfer,  in whole or in part, of this Warrant or
the Stock  issuable  upon exercise of this Warrant  might  reasonably  involve a
public  offering  of the same  contrary  to the  investment  representations  in
Section 6, the Company may require,  as a condition  precedent to such transfer,
an opinion of counsel,  satisfactory to it, that the proposed  transfer will not
involve  a  public  offering  which  is  required  to be  registered  under  the
Securities Act of 1933.  However,  no such  requirement  shall be imposed during
such time as a new registration statement or a post-effective  amendment thereof
covering the Stock or part thereof being  transferred  is in effect.  Subject to
the foregoing,  this Warrant and all rights hereunder is transferable,  in whole
or in part, on the books of the Company to be maintained for such purpose,  upon
surrender of this Warrant at the principal office of the Company,  together with
a written assignment of this Warrant duly executed by the Holder or its agent or
attorney.

         (b) This  Warrant  and the name and  address  of the  Holder  have been
registered in a Warrant  Register  that is kept at the  principal  office of the
Company,  and the Company  may treat the Holder so  registered  as the  absolute
owner of this Warrant for all purposes.
