GREENSHIFT RELEASES SHAREHOLDER LETTER

NEW YORK,  N.Y.,  June 22, 2007 - GreenShift  Corporation  (OTC Bulletin  Board:
GSHF) chairman and chief executive officer, Kevin Kreisler, issued the following
letter to GreenShift's shareholders today:

Dear Shareholders:

We have accomplished much since GreenShift  initiated  operations in April 2005,
and we are  proud  and  excited  by the  progress  we have  made in our  various
operations.  But we have a number of significant  issues that we face today that
are in need of correction.

Chief among these  issues is that of share  value.  We believe  that the current
share price of each of our companies  does not  accurately  reflect the value of
what we have built.

Our mission is to create valuable opportunities for many people and companies to
use resources more efficiently and to be more profitable. To accomplish this, we
target and reduce or eliminate consumption inefficiencies by

>>   developing  and  implementing  incremental  advances  in  technologies  and
     business practices

>>   that  leverage  established  infrastructure  and  distribution  channels to
     enable increased and sustainable profits

>>   by decreasing the  consumption  of natural  resources and the generation of
     wastes and emissions.

We are  focused on  implementing  this model first in the  agriproducts  sector,
where we have sought out  applications  of  technology  that create  value-added
co-product and waste extraction and refining opportunities.

In the past  two  years  GreenShift  and its  affiliated  companies  raised  and
deployed about $40 million in capital to  successfully:  (i) acquire and develop
technologies that are capable of cost-effective "plug-and-play" integration into
existing  agriproducts  plants;  (ii)  develop  the  go-to-market   capabilities
necessary to bring these  technologies  to market;  (iii)  complete  early-stage
commercialization  and  finalize  the  application  of  the  first  two  of  our
technologies;   (iv)   sell  and   commission   early-adopter   and   commercial
implementations  of these two  technologies;  (v) execute a number of agreements
that are vital to the foundation of our long term commercialization  plans, and,
importantly,  (vi) initiate positive cash flows. Some of the more significant of
our technology-centric achievements include:

>>       Corn Oil Extraction

          Our process  engineering and technology transfer company, GS CleanTech
          Corporation,   acquired  its   patent-pending   Corn  Oil   Extraction
          technology in early 2006. This technology  efficiently  extracts crude
          corn  oil  from a  co-product  of  ethanol  production  at  rates  and
          efficiencies  that outstrip any conventional  extraction  process.  GS
          CleanTech has executed 6 contracts with ethanol producers that provide
          for the  extraction  and  purchase of more than 30 million  gallons of
          crude corn oil.  Two early  adopter  extraction  systems were sold and
          commissioned  during  2006,  and we  recently  commissioned  our first
          deployment where we retain the right to buy and sell the extracted oil
          at rate equal to more than 1.2 million  gallons per year.  This oil is
          currently  worth upwards of $1.50 per gallon and GS CleanTech has just
          begun to sell oil this month.  An additional 4 systems are planned for
          deployment  over the  balance  of this year and we have  many  similar


          potential  contracts  in our  sales  pipeline.  If all  of  these  new
          contracts are signed,  they will provide us over 60 million additional
          gallons of corn oil extraction potential.

>>       Biodiesel Production Equipment

          Our  fuel  production  company,  GS  AgriFuels  Corporation,  recently
          acquired a biodiesel  technology  provider,  NextGen Fuel, Inc., which
          had  developed  and  completed  early  stage  commercialization  of  a
          patent-pending  continuous flow biodiesel system. The NextGen systems,
          which  include both direct and  transesterification,  are skid mounted
          and sized to produce 5 million or ten 10 million  gallons of biodiesel
          per year.  Traditional  processes  typically  require several hours to
          complete the  conversion of qualified  vegetable  oils and animal fats
          into biodiesel;  we intensify and idealize the conditions  under which
          this conversion  occurs and we are  consequently  able to complete the
          conversion in minutes  instead of hours - at a much smaller scale than
          traditional  processes,  and at reduced capital and operating costs as
          compared to  traditional  processes.  These  benefits also allow us to
          efficiently convert a broader array of feedstocks than any traditional
          process that we are aware of. Since acquiring NextGen we have improved
          and refined the technology,  completed  commercialization and recently
          successfully shop-tested two systems for U.S. clients.

>>       Development of Corn Oil Biodiesel Production Facilities

          We recently announced the execution of letters of intent that call for
          GS CleanTech to design,  build and integrate an additional 12 corn oil
          extraction  systems  with  integral  biodiesel  systems  at 4 separate
          ethanol  production  facilities.  In addition,  GS CleanTech  recently
          executed an agreement for the  extraction  of about 7 million  gallons
          per  year  of  corn  oil  at an  ethanol  facility  next  to one of GS
          AgriFuels'  planned  biodiesel  facilities.  In all, these planned new
          extraction  systems and  biodiesel  facilities  will first extract and
          then  convert  about  37  million  gallons  of  crude  corn  oil  into
          biodiesel.  GS CleanTech and GS AgriFuels  will work together on these
          developments  -  GS  CleanTech  will  provide  and  sell  engineering,
          construction and technology  transfer services in return for a mixture
          of  process  engineering  and  plant  construction  sales,  technology
          royalties and selected  feedstock sales, and GS AgriFuels will provide
          its  biodiesel  systems and invest in the various  projects.  If these
          letters of intent are successfully  converted into executed  contracts
          and the relevant  projects are financed,  these prospects would result
          in a total of more than $90 million in additional process  engineering
          and equipment  sales and ongoing  royalties for GS CleanTech and about
          $50 million per year in ongoing  biodiesel  sales for GS  AgriFuels at
          current biodiesel prices.

That said, our successes are clearly not translating into share value. Our view
is that the message is getting lost in the complexities of our capital
structure.

We had an entirely  different  outcome in mind when we formed  GreenShift  as an
investment  company and seeded our various  companies and  technologies.  Recall
that our original  structure included a number of public platform companies that
were intended to focus on specific sectors - clean technology development, clean


fuels  production,  clean energy  production and  environmental  services.  This
structure was  established  to enable each company to raise capital with its own
balance sheet, and its own equity, in order to support its own business model. A
big part of the reason for this was that the  investment  theses were  different
from one business focus to the next - the  structures  and  valuations  used for
financing  emerging  clean tech R&D, for example,  are very different from those
used to finance mature fuel or power production.  At bottom,  this structure was
initially  very  successful  as it resulted in the  financing,  acquisition  and
development of all of our core technologies and operations.

Last  year,   however,   after   recognizing  the  significance  of  the  market
opportunities  presented by a few of our  technologies in the rapidly  expanding
renewable  fuels market,  we narrowed our focus to financing and  supporting the
development  and  iterative  roll-out  of our leading  technologies  and related
operations.

Today, we have commercialized  essential technologies that have been designed to
service needs that few (if any) others currently have the capability to fulfill,
and we have  positioned  these  technologies  for  deployment in an  expansively
growing renewable fuels market.

The opportunities in front of us in the biomass-derived  fuels sector are simply
tremendous  and we would be remiss if we were to commit  capital to anything but
implementation in this vertical given our technological advantages.

With this narrowing in focus, the capital structure that we successfully used to
seed our technologies has become a costly  distraction and an unnecessary  drain
on  resources.  Therefore,  we have  initiated  steps to  simplify  our  capital
structure and increase the  transparency  of our  operations.  This is a process
that I believe to be  critical  to our growth  and I am  committed  to seeing it
through to an expedient and cost-effective conclusion.

Our plan  involves (1) merging GS CleanTech  into  GreenShift  and,  separately,
merging GS Energy into GS AgriFuels,  (2) liquidating  non-core assets,  and (3)
restructuring  and refinancing our debt while we (4) increase sales and earnings
in our core business units.

1.       Complete Pending Mergers

We believe  that the  GreenShift  - GS  CleanTech  and GS  AgriFuels - GS Energy
mergers  will help to reduce  operational  overlap and  redundancies,  promote a
unified vision among our employees,  reduce the confusion created by our current
structure  among   customers,   vendors,   creditors,   shareholders  and  other
stakeholders,  reduce  the  focus,  capital,  and other  resources  required  to
administer  multiple  public  entities,  and  increase  our  ability to focus on
creating value for our shareholders. Updates on these transactions follow:

     >>   GS AgriFuels - GS Energy Merger

          To complete  this merger,  we need to prepare and file a  registration
          statement and secure regulatory approval. We have completed nearly all
          of the requirements for the filing of this registration  statement and
          are now only waiting on the final third party legal and tax  opinions.
          We expect to receive these opinions  shortly and that we will file the
          registration  statement  before  the  end of  this  month.  GS  Energy
          shareholders  will  receive 1 share of GS  AgriFuels  for every  1,000
          shares  held in GS Energy on the  record  date for this  merger.  This
          merger can take  anywhere  from 3 to 6 months to  complete,  depending
          nearly entirely on how long it takes to secure regulatory approval.


     >>   GreenShift - GS CleanTech Merger

          The  completion  of this  merger  will also  require  the  filing  and
          approval of a registration  statement. We have started to prepare this
          registration statement and our goal is to file it as soon as possible.

          GS CleanTech shareholders will receive 1 share of GreenShift for every
          3 shares of GS  CleanTech  held on the  record  date for  merger  This
          exchange  ratio was set based on the market  price for both  stocks at
          the time we announced the merger.  Given the negative  market response
          to our original plan to complete  this merger,  we considered a number
          of ways to improve the rate of exchange for minority  shareholders  of
          both GS CleanTech and  GreenShift,  from simply  changing the exchange
          rate,  which could have  significant  negative tax  consequences on GS
          CleanTech's minority  shareholders,  to financing a cash buyback of GS
          CleanTech  stock,  which  would  not  be  fair  to  the  GS  CleanTech
          shareholders at current market prices.

         We settled on decreasing my ownership of the combined company down to
         60% and eliminating all preferred stock upon completion of the merger.
         GreenShift currently owns about 80% of GS CleanTech and I currently own
         about 80% of GreenShift in the form of preferred stock. We believe that
         we can prevent negative tax consequences for the minority shareholders
         of both companies simply by adjusting the conversion features of my
         preferred ownership in GreenShift. Importantly, this is intended to
         have the effect of increasing the aggregate percentage of the combined
         company owned by the minority shareholders of both companies from 20%
         to 40%.

2.       Liquidate Non-Core Assets

We will liquidate or otherwise  divest  ourselves of any investment,  company or
asset that is not  critical  to our  continued  operation  and  growth.  We have
already sold off a non-core engineering unit and a minority  investment,  and we
are exploring  the sale of several of our other  minority  investments  (we will
retain our existing stakes in Sterling Planet and  TerraPass).  In addition,  we
are ceasing all R&D activity that does not complement our core  technologies and
business lines.

We have also negotiated for the sale our majority stake in GS Carbon Corporation
to Seaway Capital,  Inc., a growth equity and leveraged buyout company. Prior to
the sale we will transfer all of our  investments,  intellectual  properties and
existing  operations  out of GS Carbon  into GS  CleanTech.  The  transfer to GS
CleanTech  and the  subsequent  sale to Seaway  will occur on or before June 30,
2007.  Seaway's  plans for the  remaining  GS Carbon  public  shell  include the
acquisition  of  Seaway's  majority  stake in a  retail  big box  chain  and the
financing and  acquisition of other targeted  retail chains with an aggregate of
more than $30 million in sales. Notably, Seaway has already received term sheets
for the financing necessary to support its acquisition plans.

3.       Restructure and Refinance Debt

We have reduced our consolidated  debt by about $5 million over the past several
months through a combination of cash payments and equity conversions.  We expect
to effect further significant  reductions over the balance of this year. Most of
the future  reductions will occur through cash payments,  since we expect equity
conversions to soon cease for the foreseeable future.


We need to  restructure  and then  refinance  our  remaining  debt. We have held
favorable  initial  discussions  with  our  senior  creditors,  each of whom has
indicated a  willingness  to  materially  improve the terms of our existing debt
financing in ways that support our  consolidation  process given the progress of
our operations and our payment  history.  We are accordingly  optimistic that we
will be able to  restructure a significant  amount of our debt in the near term.
We are working on this now.

We  will,  however,  and even  after  this  restructuring,  need to  reduce  and
refinance all of our remaining debt. We plan to do so with a combination of cash
flows  and  lower  cost  debt and  equity  that we  bring in at the much  higher
valuations justified by the performance of our core operations.

4.       Execute in Core Businesses

At the  conclusion  of the  mergers  and  other  transactions  described  above,
GreenShift will have two majority-owned public subsidiaries, GS AgriFuels and GS
EnviroServices, as shown here:


                            GreenShift Corporation
                                (OTCBB: GSHF)
                                       |
          |-------------------------------------------------------|
          |                                                       |
    GS Agrifuels                                          GS EnviroServices
   (OTCBB: GSGF)                                            (OTCBB: GSEN)
                                     

The operations of each company will be as follows:

>>       GreenShift Corporation
>>       Process Engineering & Plant Construction Services
>>       Technology Licensing
>>       Feedstock Extraction & Sales
>>       Early Stage Technology Acquisition and Development
                                                                     
>>       GS AgriFuels Corporation (OTC Bulletin Board: GSGF)            Majority Owned Public Subsidiary
>>       Biofuels Production Equipment Manufacturing & Sales
>>       Biodiesel Production & Sales
>>       Other Biomass Derived Fuel & Energy Production & Sales
>>       Oilseed Crushing & Vegetable Oil Sales

>>       GS EnviroServices, Inc. (OTC Bulletin Board: GSEN)             Majority Owned Public Subsidiary
>>       Industrial Waste Management Services
>>       Environmental Engineering Services
>>       Site Remediation Services


As an example of our revenue generating potential moving forward, the completion
of  construction  and full  deployment of a total of just 30 million gallons per
year of corn oil extraction with integral biodiesel production  capability could
generate about $72 million in process  engineering and plant  construction sales
and  about $3  million  in  annual  royalties  for the  merged  GreenShift  - GS
CleanTech.  Our target is to ultimately  deploy 120 million  gallons of corn oil
extraction and biodiesel production capability.

GS AgriFuels,  as the majority owner of these biodiesel  production  facilities,
would generate about $85 million per year in ongoing biodiesel sales with better
than 25% EBITDA margins at current market prices.  Given the contracts,  letters
of intent and other recent  developments  detailed  above, GS AgriFuels could be
producing  biodiesel at the 30 million  gallon per year run-rate in as little as
12 months.


In addition,  we believe that GS  AgriFuels  can generate  well in excess of $50
million  per year in  equipment  sales,  and that GS  AgriFuels'  oilseed  crush
division,  Sustainable  Systems, can produce more than $70 million in annualized
vegetable oil and biodiesel  sales after the  completion of the expansion of its
Montana based crush facility later this year.

Finally, GS EnviroServices,  which is currently generating about $16 million per
year in sales,  can be expected to grow its sales at an annual rate of more than
20%  for  the  next  few  years  given  its  recently   completed   and  planned
acquisitions.

The Path Forward

Our  technologies  are  robust,   scalable,   energy  efficient,   modular  and,
importantly,  capable of rapid and  cost-effective  "plug-and-play"  integration
into the existing  agribusiness  infrastructure.  These  advantages  converge to
enable the  refining of many  different  alternative  feedstocks  into clean and
renewable  energy and several  different clean fuels  cost-effectively  at small
scales. We believe that this capability is highly valuable because it enables us
to reduce commodity risk by creating  opportunities to manage  production assets
in response to fluctuating  market  conditions.  No single  conventional  or new
technology or group of technologies  that we are aware of can currently  achieve
this.

Our  commercialization  plan  for  these  technologies  involves  the  iterative
integration and synergistic application of several technologies into traditional
agriproducts   plants  in  ways  that  enable  us  to  upgrade   production  and
cost-average down the capital and operating costs traditionally  associated with
renewable fuel production.  Our intention is to commercialize  and generate cash
flows from our technologies according to the following roll-out schedule:

         Step 1 corn oil extraction
         Step 2 integral biodiesel production
         Step 3 integral biomass gasification for heat and power applications
         Step 4 integral biomass gasification for liquid fuels applications
         Step 5 integral bioreformation of carbon dioxide into algal biomass and
                additional liquid fuels

Importantly,  each  step is  designed  to  integrate  and work  with each of the
previous  steps as well as the host  facility  to  capitalize  on all  practical
operating synergies. The commercialization process for Steps 1 and 2 is complete
and we are actively implementing a go-to-market based on these technologies. The
technologies needed for Steps 3 and 4 are nearly complete with their early-stage
commercialization   process  and  we  plan  to  start  our  marketing  of  these
capabilities later this year. The technologies  needed for Step 5 are still deep
in the R&D stage and require  additional  capital to prove out,  but we are very
committed to bringing a cost-effective  implementation of bioreactor  technology
to market - this a key strategic initiative for GreenShift moving forward.

On the  morning  after the U.S.  Senate  passed a bill that calls for  increased
ethanol production,  our focus on upgrading  traditional ethanol facilities with
"plug-and-play"  modular  technology was never more timely.  We will continue to
remain  relentlessly  focused on developing and implementing  technologies  that
make existing and new ethanol  plants more  efficient.  We will then do the same
for other  traditional  agriproducts  plants,  such as oilseed  crush plants and
animal and livestock processing plants, and upgrade these plants into integrated
multi-feedstock, multi-fuel biorefineries.


Our long-term strategy is to focus on the inevitable  consequences of the way we
use natural resources to make things, and to extract  opportunities for positive
economics by simultaneously  increasing production efficiencies and reducing the
upstream  and  downstream  burdens of that  production  on our  ecosystem.  With
increasing burdens on natural resources globally,  both at the beginning and end
of product supply chains,  we must simply be smarter about how we use resources.
GreenShift's  long  term  mission  is to  make  a  significant  contribution  to
achieving this.

For the time being, however, we will remain focused on sales and earnings growth
through the deployment and  commissioning  of corn oil extraction  systems,  the
sales of biodiesel equipment,  the financing,  construction and operation of our
co-located corn oil biodiesel production facilities, the expansion and operation
of our oilseed crush plant, and the growth of our environmental services group.

While the results  have not been  obvious and the impact has not yet  translated
into share value,  our  operations  have made  extraordinary  strides in a short
period of time and they are picking up steam.  We will  continue  these  efforts
while we rationalize our capital structure as quickly and as cost-effectively as
possible. We appreciate your patience through that process.

We intend to announce details shortly relative to the scheduling of a conference
call that we would like to hold next week to respond to shareholder questions.
We are grateful for your continued interest and support, and we look forward to
our next communication.
