      Contractor
Proposal

      (the
“Agreement”)

       

      

       

       

      1.      Client's
name and address

       

      Mantra Energy
Alternatives Ltd.

      1205 – 207 W.
Hastings St.

      Vancouver,

      2.      Background

       

       

      Mantra has a patent
pending process for the "Continuous Co-Current Electrochemical Reduction of
Carbon Dioxide" (ERC), developed by Professor Colin Oloman and Dr. Hui Li in the
Clean Energy Research Centrer (CERC) at University of British Columbia in
Vancouver, Canada. The ERC process takes carbon dioxide and water, combined with
electricity, to produce fuels and chemicals such as formic acid, formates and
oxygen. The investigation of ERC process was summarized in four papers and
published in various journals.

       

      Carbon dioxide is a
greenhouse gas and
a main contributor to climate change. Scientists and innovators are therefore
looking at methods to deal with the CO2 released so that it doesn’t enter our
atmosphere. These methods currently include capturing the gas and injecting it
underground for storage in a process called carbon sequestration. However, as of
yet, a full carbon capture and storage system for large-scale power plants is
not a proven cost effective option.  Safety is not
established.

       

      The ERC process
offers an innovative alternative to carbon sequestration with many potential
advantages. The first advantage is that the ERC, instead of addressing carbon
dioxide as the problem, harnesses its chemical properties as part of the
solution. Capitalizing on the abundance of carbon dioxide being released from
fossil fuel combustion the ERC converts CO2 to useful, financially profitable
products. The second advantage is that the process is driven by electric energy
that can be taken from an electric power grid supplied by hydro, wind, solar,
tidal or nuclear energy (all renewable). Lastly, there is potential for this
technology to be applied in a closed-loop fuel cell cycle, whereby carbon
dioxide is converted into a fuel (formic acid) that is then used in a fuel cell
to generate energy.

       

       

      3.      Objective

       

         Mantra will contract
Kemetco Research, a technology development and scientific contract research
company in Richmond, BC, Canada, to launch and operate the ERC process
development project.

       

      
        	
                ·  

              	
                The overall
      objective is to establish the technical basis for electro-reduction of
      carbon dioxide to formate via a continuous electrochemical
      reactor.  The details of the process to be undertaken have been
      agreed upon and disclosed in the proposal presented to the Mantra on
      January 28, 2009 (the “Proposal”).
