     corporation (the "Company") the sum of twenty-five thousand
     dollars ($25,000) in the event the Company is unable to raise a
     minimum of $25,000 from its initial public offering of its

consideration  of  five  thousand  (5,000)  common  shares  of  Cogen.  Cogen
additionally  agrees  to  issue  consideration  of  ten thousand (10,000) common
shares  of  Cogen,  issued  pro rata, to the other Assignors per Schedule I. Mr.
Williams  acknowledges that the above consideration is fair and reasonable value
for  the  Intellectual  Property  assigned  by  this  agreement.

                                    EXHIBIT A
                           COGEN SOFTWARE DESCRIPTION

GENERAL  DESCRIPTION
Cogen  is a software program for rapidly searching the genomes. It extracts from
the genome/s a highly focused list of Target Genes that match the specifications
entered  by the user. The list is processed to reduce the number of Target Genes
in  the  results. The results are returned as either a cursor table or as a file
of  output  depending  on  user  request.

ENVIRONMENT
The  software  runs  in  a  networked  environment  utilizing  TCP/IP to connect
together  the  server  and  the clients. The server operates as a data store and
processing.  As  specified,  the  server  needs  to  be  a  Relational  Database
Management  System  (RDMS)  capable of running Remote Procedure Calls (RPC). The
server  as  implemented runs on a Unix system running Oracle 8i. The RPC modules
are  a combination of Structured Query Language queries and C language functions
for  processing.  As  specified,  the  triggering  of the server RPC is from the
client  software running on local user machines. As implemented currently, these
are  HTML web pages running JavaScript. It is anticipated that a client software
package  could  be  created  using  Visual  Basic  with  little  effort.

MAIN  PROCESSES

In  general,  the  user  will  specify  one  or more SQL queries and one or more
processing  functions  to be applied to the output of the query. These RPC's are
run  in sequence against the main data store by the RDMS and the final result is
returned  to  the  user.

There  are several variant paths of execution. To speed the processing time, the
RPC's  may  call  the  search  tag  database (tags). Tags consist of precompiled
results  from  the main data store for common search terms. The user may specify
results  from  several genomes or multiple results from the same genome and so a
step  to  combine  the  SQL  results  before  processing  may  be  required.

RPC  MODULES

SQL  queries: These queries define the first cut of data to be selected from the
main  database. They include the ability to specify the content and relationship
of  any  piece  of  data  to  be returned from the main database. Updates to the
queries  are  expected  to be a major focus of expansion for the software as new
genomes  become  available.

Processing  Functions:  These  are the functions that reduce the large amount of
data  returned  by  the SQL functions into higher quality results. These include
Culling, bi-directional list eliminations, protein incompatibility tests, Blast,
Folding, single codon selection and other tests which serve to eliminate data or
rank  its  relevance.  These  functions are the core purpose of the software and
future  expansion  of  these  functions as new techniques are developed are made
possible  by  the  RPC  architecture.

Combinatory  Functions:  These are the functions that merge SQL function results
into  a  single  result  ready for processing by the processing functions. These
include  but are not limited to the binary logic functions such as AND, NOT, OR,
XOR,  NAND.  It  also  includes  such relational and SQL type functions as JOIN,
UNION  and  DISUNION.  For example, a search of the mouse, ape and human genomes
for  a  particular  gene  will  require  all of the separate results be combined
before  processing  using  one  or more functions such as JOIN, OR, NAND or XOR.
These  are  utility  functions  and generally should be widely applicable across
genomes  but  must  be  validated  when  adding  new  genomes.

DELIVERY  SPECIFICATION

The search tag database will be provided in dbf format on several compact disks.
The  search  tags are not themselves copyrighted, as they are simply a condensed
nomenclature  of  the  public  genome  information.

Source  code for the RPC  modules will be  made available as C++ source code and
headers along with required make and browser files. SQL modules will be provided
as  text  files  and imported into the RDMS. The completeness of the source code
will  be  demonstrated by compilation on the machine designated by the purchaser
and  a  binary  comparison  made  of  the  result  against a known working copy.

The  HTML  pages  will be downloaded and saved from the current website onto the
target  machine  by  the  assignee.

The  Assignor  will demonstrate to the assignee's satisfaction that all data and
code  perform  as  intended  on  the designated machine/s as of the date of this
Agreement.

It  is  the  responsibility  of  the  assignee  to  provide a functioning server
environment including Oracle 8i and a client machine connected to the server via
TCP/IP  prior  to  commencement  of  delivery.
