AMENDED AND RESTATED FORBEARANCE AGREEMENT

     THIS AMENDMED AND RESTATED  FORBEARANCE  AGREEMENT (the Agreement") is made
this 11h day of January,  2008  between YA Global  Investments,  L.P.  (formerly
known as Cornell Capital  Partners,  L.P.) ("YA Global"),  Viridis Capital,  LLC
("Viridis"), GreenShift Corporation ("GreenShift"), and GS CleanTech Corporation
("GS CleanTech")  (Viridis,  GreenShift,  and GS CleanTech shall be collectively
referred to herein as the "GS  Parties").  This  Agreement  shall  supersede the
forbearance  agreement (the "Forbearance  Agreement") entered into on October 9,
2007 between YA Global and GreenShift.

     WHEREAS,  this  Agreement is intended to amend,  replace and  supersede the
Forbearance  Agreement  and to add Viridis and GS  CleanTech  as a party to such
agreement.

     WHEREAS,  YA Global is the  holder of the  secured  convertible  debentures
issued by  GreenShift  (the  "GreenShift  Debentures")  set forth on  Schedule I
attached hereto, and YA Global has previously declared the GreenShift Debentures
to be in default for (i) failure to timely file a registration  statement,  (ii)
failure to obtain  effectiveness of such registration  statement,  and (iii) the
CleanTech Default as set forth below (collectively,  the "GreenShift Defaults");
and

     WHEREAS,  YA Global is the  holder of the  secured  convertible  debentures
issued by GS  CleanTech  (the  "CleanTech  Debentures")  set forth on Schedule I
attached  hereto,  which  CleanTech  Debentures  were in default for reasons set
forth below; and

     WHEREAS,  YA Global is the  holder of the  secured  convertible  debentures
issued by GS  AgriFuels  (the  "AgriFuels  Debentures")  set forth on Schedule I
attached hereto (the GreenShift  Debentures,  CleanTech Debentures and AgriFuels
Debentures  shall,  where relevant,  be  collectively  referred to herein as the
"Debentures"),  which  AgriFuels  Debentures  were in default for the failure to
timely register the shares issuable upon conversion of the AgriFuels  Debentures
(the "AgriFuels Default"); and

     WHEREAS,  YA Global and GreenShift are parties to a letter  agreement dated
June 27,  2007 (the  "June  Agreement")  pursuant  to which YA Global  agreed to
forego  exercise of its remedies for the defaults for a period  terminating if a
further default were to arise after the date of the June Agreement; and

     WHEREAS,  on June 30,  2007,  GS  CleanTech,  a subsidiary  of  GreenShift,
defaulted in its  obligation to satisfy a $1,000,000  debenture  issued to Kerns
Manufacturing Corp. (the "CleanTech Default"),  and said default by GS CleanTech
is an "event of default" by  GreenShift  and by GS  CleanTech  as defined in the
GreenShift  Debentures and the CleanTech Debentures (the GreenShift Default, the
CleanTech Default,  and the AgriFuels Default shall be collectively  referred to
herein as the "Existing Defaults"); and

     WHEREAS,  YA Global  has  asserted  its  rights by reason of the  CleanTech
Default, and has demanded assurances that its rights as a secured party will not
be diminished thereby; and

     WHEREAS, for that reason the parties wish to make such arrangements as will
facilitate a  liquidation  of certain  assets by YA Global to offset any adverse
impact of the  CleanTech  Default (but  Greenshift  (on behalf of itself and its
affiliated  entities) agrees and  acknowledges  that it shall be prohibited from
using any cash or other assets that secure any YA Global  collateral  to pay all
or any part of the amounts owed to Kerns).

         NOW, THEREFORE, it is agreed:

1.   Forbearance Agreement. In reliance upon the representations, warranties and
     covenants of the GS Parties contained in this Agreement, and subject to the
     terms and  conditions of this  Agreement,  YA Global agrees to forbear from
     exercising  its rights and remedies  under the Debentures or applicable law
     in respect  of or  arising  out of the  Existing  Defaults,  subject to the
     conditions, amendments,  modifications contained herein for the period (the
     "Remedy  Period")  commencing on the date hereof and continuing for so long
     as (i) The GS Parties  strictly  comply  with the terms of this  Agreement,
     (ii) there is no  occurrence or existence of any Event of Default under any
     of the  Debentures,  other  than the  Existing  Defaults,  and (iii) the GS
     Party's  comply with the  condition in paragraph 5. Upon the  expiration or
     termination  of the Remedy  Period,  the  agreement of YA Global to forbear
     shall automatically and without further action terminate and be of no force
     and  effect,  andYA  Global  shall  retain  all of  its  rights  under  the
     Debentures,  including  the right to enforce any  remedies  available to it
     thereunder  by reason of the  Existing  Defaults.  This is a one-time  only
     forbearance.

2.   Conversion  Restrictions.  The conversion restrictions set forth in Section
     3(a)(ii) or 3(b) of the Debentures shall remain in full force and effect at
     all times,  notwithstanding  the  declaration  of any default by YA Global.
     Furthermore,  in no event shall YA Global have the right to acquire,  vote,
     or receive from the GS  CleanTech  such number of shares of common stock of
     GS EnviroServices,  Inc. ("GS EnviroServices")which  would cause YA Global,
     together  with  its  affiliates,  to  beneficially  own (as  determined  in
     accordance  with Section 13(d) of the  Securities  Exchange Act of 1934 and
     the rules promulgated  thereunder in excess of 9.99% of the common stock of
     GS EnviroServices (the "Ownership Limitation") unless YA Global waives such
     limitation by providing 65 days' advance  written  notice.  This  Ownership
     Limitation  of GS  EnviroServices  common stock shall replace and supersede
     any prior limitations imposed upon YA Global.


3.   Pledged Shares.

          Global,  inter alia, the following shares (which shall collectively be

          GS Party                 Pledged Shares                                    Issuer
          ------------------------ ------------------------------------------------- --------------------------------
                                                                               
          Viridis                  1,000,000  shares  of Series C  Preferred  Stock  GreenShift
                                   Convertible into common stock
          ------------------------ ------------------------------------------------- --------------------------------
          Viridis                  750,000  shares  of  Series  C  Preferred  Stock  GS CleanTech
                                   Convertible into common stock
           ------------------------ ------------------------------------------------- --------------------------------
          GSCleanTech              1,000,000 shares of Series C
                                   Preferred Stock GS Energy Corporation
                                   Convertible into common stock
          ------------------------ ------------------------------------------------- --------------------------------
          GS CleanTech             6,266,666   shares   of   common   stock  of  GS  GS EnviroServices
                                   EnviroServices  (defined as "GS  Pledged  Shares
                                   Pool 1")
          ------------------------ ------------------------------------------------- --------------------------------
          GS CleanTech             8,733,333   shares   of   common   stock  of  GS  GS EnviroServices
                                   EnviroServices  (defined as "GS  Pledged  Shares
                                   Pool 2")
          ------------------------ ------------------------------------------------- --------------------------------


          To remedy the Existing Defaults, YA Global shall be entitled to demand
          conversion  of the  Pledged  Shares  (in  the  case of the  shares  of
          Preferred  Stock  convertible  into common  stock)  into common  stock
          issued in its name,  or the transfer (in the case of the common stock)
          of the common  stock to its name.  YA Global  shall make such  demands
          from time to time in tranches  such that at no time will YA Global own
          more than 4.99% of the outstanding  common stock in any of GreenShift,
          GS CleanTech or GS Energy,  and no more than the Ownership  Limitation
          of GS  EnviroServices.  The GS Parties will provide such assistance as
          is necessary to cause  GreenShift,  GS CleanTech or GS Energy to honor
          the conversions on the schedule set forth in the governing instruments
          for its preferred stock. The Buyer shall not be entitled to demand the
          transfer  of the GS Pledged  Shares Pool 2 unless and until there is a
          default or event of default under the secured convertible debenture in
          the   original   principal   amount   of   $2,000,000   issued  by  GS
          EnviroServices to the Buyer on the date hereof.


     b.   The shares of common stock  issuable to YA Global upon the  conversion
          of the Pledged Shares and the Pledged Shares  transferred to YA Global
          are collectively referred to herein as the "Shares."

4.   Application  of  Proceeds.  In order to  facilitate  administration  of the
     liquidation  of the  Shares,  the  "Net  Proceeds"  of each  conversion  or
     transfer into the Shares shall be deemed to equal to the product of (x) 90%
     of the lowest  volume  weighted  average price during the five trading days
     preceding  the  conversion  date or date YA  Global  provides  notice to GS
     CleanTech  to transfer  such Shares (as  applicable)  and (y) the number of
     Shares  comprising such  conversion or transfer.  The Net Proceeds shall be
     applied by YA Global in its sole discretion to the  outstanding  principal,
     interest,  and other charges owed under the Debentures  until all of the GS
     Parties'  obligations  under the  Debentures  have been  satisfied in full.
     Promptly upon each application of Net Proceeds,  YA Global shall notify the
     GS Parties as to its application.

5.   Further Agreements.  The GS Parties covenant and agree the principal amount
     outstanding under the Debentures shall be reduced by $13,500,000 by January
     10, 2009 whether  through  reductions  in accordance  with this  Agreement,
     conversions, cash payments, or otherwise.

6.   Nothing  contained in this Agreement shall constitute a waiver by YA Global
     of any default or event of  default,  whether  now  existing  or  hereafter
     arising (including,  without limitation,  the Existing Defaults).  Instead,
     this Agreement  shall only  constitute an agreement by YA Global to forbear
     from  enforcing  its  rights and  remedies  with  respect  to the  Existing
     Defaults  upon the terms and  conditions  expressly  set forth  herein.  YA
     Global  reserves  all  of  its  rights  and  remedies,  including,  without
     limitation, the right to declare an Event of Default in accordance with the
     terms of the Debentures and other transaction documents except with respect
     to the Existing Defaults during the Remedy Period as set forth herein.
