records for the period between  February 1, 2004, and the Closing Date nor shall

     All representations and warranties in this Agreement,  or in any instrument
or document furnished transactions contemplated hereby shall survive the Closing

expire on the first anniversary of the Closing Date, except that claims, if any,
asserted in writing  prior to such first  anniversary  identified as a claim for
indemnification  pursuant to this Article 8 shall survive until finally resolved
and  satisfied in full.  All  covenants and  agreements  contained  herein shall
survive until fully  performed in accordance with their terms and any recoveries
from third parties.

     8.1. Indemnification  Provisions -Buyers'  Representations,  Warranties and
Covenants.  The Buyers agree to indemnify  Cognigen,  its directors and officers
from and  against the  entirety  of any  charges,  complaints,  actions,  suits,

fees,  including  all  attorneys'  fees and  costs,  which  Cognigen  may suffer
resulting  from,  arising out of,  relating to or caused by the breach of any of
the  Buyers'  representations,   warranties  and  covenants  contained  in  this
Agreement.

     8.2. Indemnification  Provisions - Cognigen's  Representations,  Warranties
and  Covenants.  Cognigen  agrees to  indemnify  the Buyers from and against the
entirety of any charges,  complaints,  actions,  suits, damages,  claims, costs,
amounts  paid in  settlement,  taxes,  liens,  expenses or fees,  including  all
attorneys' fees and costs,  which the Buyers may suffer resulting from,  arising
out  of,   relating   to  or  caused  by  the   breach  of  any  of   Cognigen's
representations, warranties and covenants contained in this Agreement.

     8.3.  Claims for  Indemnification.  In the event of the  occurrence  of any
event which any Party asserts is an indemnifiable event pursuant to this Article
8, the Party claiming  indemnification  (the "Indemnified  Party") shall provide
prompt   notice  to  the  Party   required  to  provide   indemnification   (the
"Indemnifying  Party"),  specifying in detail the facts and  circumstances  with
respect  to such  claim and the basis for  which  indemnification  is  available
hereunder. If such event involves the claim of any third party, the Indemnifying
Party shall have the right to control the defense of  settlement  of such claim;
provided,  however,  that  (a)  the  Indemnified  Party  shall  be  entitled  to
participate  in  the  defense  of  such  claim  at  its  own  expense,  (b)  the
Indemnifying  Party shall obtain the prior written  approval of the  Indemnified
Party (which  approval  shall not be  unreasonably  withheld or delayed)  before
entering  into any  settlement  of such claim if,  pursuant to or as a result of
such  settlement,  injunctive  or other  non-monetary  relief  would be  imposed
against the Indemnified  Party, (c) the Indemnifying Party shall not be entitled
to control  (but shall be  entitled  to  participate  at its own  expense in the
defense  of), and the  Indemnified  Party shall be entitled to have sole control
over,  and shall assume all expense with respect to the defense or settlement of
any claim to the extent such claim seeks an order, injunction or other equitable
relief against the  Indemnified  Party which,  if successful,  could  materially
interfere  with  the  business,  operations,  assets,  condition  (financial  or
otherwise) or prospects of the Indemnified Party;  provided that the Indemnified
Party shall provide written notice to the Indemnifying  Party of its election to
assume  control  over the defense of such claim  pursuant to this Section 8.4 if
the Indemnifying  Party is entitled but fails to assume control over the defense
of a claim as provided in this Section  8.4. If the  Indemnified  Party  assumes
control of the defense of a claim as permitted hereunder,  the Indemnified Party
shall  obtain  the prior  written  approval  of the  Indemnifying  Party  (which
approval shall not be unreasonably withheld or delayed) before entering into any
settlement  of such  claim if,  pursuant  to or as a result of such  settlement,
injunctive  or  other   non-monetary   relief  would  be  imposed   against  the
Indemnifying Party.

     In the event that the  Indemnifying  Party shall be  obligated to indemnify
the Indemnified Party pursuant to this Article 8, the Indemnifying  Party shall,
upon  payment of such  indemnity  in full,  be  subrogated  to all rights of the
Indemnified  Party  with  respect  to the  claim to which  such  indemnification
relates.

     8.4.  Other  Remedies.  The  foregoing  indemnification  provisions  are in
addition to, and not in  derogation  of, any  statutory or common law remedy any
Party may have for breach of representation, warranty, covenant or contract.

          a. By mutual written consent of Cognigen and the Buyers;

          b. By Cognigen or the Buyers,  if all the conditions  precedent to its
     or their respective obligations hereunder have not been satisfied or waived
     prior to or at the Closing, as it may be accelerated or extended;

          c. If  Cognigen  or the  Buyers  shall  have  defaulted  or refused to
     perform in any material respect under this Agreement, or if Cognigen or the
     Buyers  should have  reasonable  cause to believe there has been a material
     misrepresentation  concerning,  or failure or breach of, any representation
     or warranty by the other, or if it appears that Cognigen or the Buyers have
     committed any unlawful acts affecting the other and such default,  refusal,
     misrepresentation,  failure,  breach  or  unlawful  act shall not have been
     fully  cured  within 30 days from the date of  delivery  of written  notice
     specifying the alleged default, refusal, misrepresentation, failure, breach
     or unlawful act; or

in accordance  with the above listed  grounds and, if the  termination is by the
Buyers,  shall be supported by a written statement signed by each of the Buyers.
Each Party's  right of  termination  under Article 9 is in addition to any other
right  it  may  have  at law or in  equity,  whether  for  damages  or  specific
performance,  and the exercise of a right to  termination  will not be deemed an
election of remedies.  Written notice of termination shall be given to the other
Party as provided in Article 11, and upon  receipt of such  termination  notice,
this Agreement shall terminate and the transactions herein contemplated shall be
abandoned without further action by the Party. On termination,  each Party shall
bear their own fees, costs and expenses.

hereby  constitute  the entire  agreement of the Parties  regarding  the subject

of   the Company's  $0.001 par value common stock ("Common  Stock")  (subject to

Common Stock ("Exercise Price").

     This Warrant is subject to the following provisions, terms and conditions:

     1. The rights  represented  by this  Warrant may be exercised by the holder
hereof,  in whole or in part,  by written  notice of exercise  delivered  to the
Company 20 days prior to the intended  date of exercise and by the  surrender of
this Warrant  (properly  endorsed if required)  at the  principal  office of the
Company and upon payment to it by official bank check of the purchase  price for
such shares.  The Company  agrees that the shares so purchased  shall be and are
deemed to be issued to the holder  hereof as the record  owner of such shares as
of the close of  business  on the date on which  this  Warrant  shall  have been
surrendered  and  payment  made for such  shares as  aforesaid.  Subject  to the
provisions  of the next  succeeding  paragraph,  certificates  for the shares of
stock so purchased  shall be delivered to the holder  hereof within a reasonable
time, not exceeding 10 days, after the rights  represented by this Warrant shall
have been so  exercised,  and,  unless this Warrant has  expired,  a new Warrant
representing  the number of shares,  if any,  with respect to which this Warrant
shall not then have been exercised  shall also be delivered to the holder hereof
within such time.

     2.  Notwithstanding  the  foregoing,  however,  the  Company  shall  not be
required to deliver any  certificate for shares of Common Stock upon exercise of
this  Warrant  except in  accordance  with the  provisions,  and  subject to the
limitations, of paragraph 5 hereof.

     3. The Company  represents  and  warrants  that this  Warrant has been duly
authorized  by all  necessary  corporate  action,  has been  duly  executed  and
delivered  and is a legal and binding  obligation  of the  Company.  The Company
covenants  and agrees  that all shares of Common  Stock which may be issued upon
the exercise of the rights  represented  by this Warrant  according to the terms
hereof  will,  upon  issuance,  be duly  authorized  and issued,  fully paid and
nonassessable.  The Company further  covenants 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 for the purpose of issue
or transfer upon exercise of the subscription  rights evidenced by this Warrant,
a sufficient number of shares of its Common Stock to provide for the exercise of
the rights represented by this Warrant.


     4. This Warrant shall not entitle the holder hereof to any voting rights or
other rights as a stockholder of the Company.

     5. The holder of this Warrant, by acceptance hereof, agrees to give written
notice to the Company  before  transferring  this  Warrant or  transferring  any
Common  Stock  issuable  or issued  upon the  exercise  hereof of such  holder's
intention to do so,  describing  briefly the manner of any proposed  transfer of
this  Warrant or such  holder's  intention as to the  disposition  to be made of
shares of Common Stock issuable or issued upon the exercise hereof.  Such holder
shall also  provide the Company  with a counsel's  opinion  satisfactory  to the
Company to the effect that the proposed  transfer of this Warrant or disposition
of shares of Common Stock may be effected without  registration or qualification
(under any federal or state law) of this  Warrant or the shares of Common  Stock
issuable or issued upon the exercise hereof. Upon receipt of such written notice
and  opinion by the  Company,  such holder  shall be  entitled to transfer  this
Warrant, or to exercise this Warrant in accordance with its terms and dispose of
the shares of Common Stock  received  upon such exercise or to dispose of shares
of Common Stock  received  upon the previous  exercise of this  Warrant,  all in
accordance with the terms of the notice delivered by such holder to the Company,
provided that an appropriate  legend  respecting the aforesaid  restrictions  on
transfer and disposition may be endorsed on this Warrant or the certificates for
such shares of Common Stock.

     6. Subject to the  provisions  of paragraph 5 hereof,  this Warrant and all
rights hereunder are transferable,  in whole or in part, at the principal office
of the Company by the holder  hereof in person or by duly  authorized  attorney,
upon surrender of this Warrant properly endorsed.  Each taker and holder of this
Warrant,  by taking or holding the same,  consents and agrees that the bearer of
this Warrant, when endorsed, may be treated by the Company and all other persons
dealing with this  Warrant as the  absolute  owner hereof for any purpose and as
the person  entitled to exercise the rights  represented by this Warrant,  or to
the  transfer  hereof on the books of the  Company,  any notice to the  contrary
notwithstanding;  but until such  transfer on such books,  the Company may treat
the registered holder hereof as the owner for all purposes.

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

     8. The Company covenants that:

          (a) All shares of Common  Stock that may be issued and  delivered to a
     holder  upon the  exercise  of this  Warrant  and  payment  of the  Warrant
     purchase price will be, upon such delivery,  validly and duly issued, fully
     paid and nonassessable.

          (b) Subject to the terms and conditions contained herein, this Warrant
     shall be binding on the Company and its  successors  and shall inure to the
     benefit of the Purchaser and the successors and assigns of the Purchaser.

          (c) If the Company fails to perform any of its obligations  hereunder,
     it shall be liable to the  Purchaser  for all  damages,  costs and expenses
     resulting from the failure,  including,  but not limited to, all reasonable
     attorney's fees and disbursements.

          (d) This Warrant cannot be changed or terminated or any performance or
     condition  waived in whole or in part  except by an  agreement  in  writing
     signed by the party against whom enforcement of the change,  termination or
     waiver is sought.

          (e) If any  provision  of this  Warrant  shall be held to be  invalid,
     illegal or unenforceable,  such provision shall be severed, enforced to the
     extent possible,  or modified in such a way as to make it enforceable,  and
     the  invalidity,  illegality  or  unenforceability  shall  not  affect  the
     remainder of this Warrant.

     9. (a) If the  outstanding  shares  of  Common  Stock  shall be  subdivided
(split) or combined (reverse split), by reclassification or otherwise, or if any
dividend  payable on the Common  Stock in shares of Common  Stock shall occur at
the time that any portion of this  Warrant  remains  unexercised  in whole or in
part, the Exercise Price and the number of shares of Common Stock  available for
purchase  pursuant to the  exercise of this  Warrant  immediately  prior to such
subdivision,  combination  or  dividend  shall be  proportionately  adjusted  as
follows:

               (i) If a net increase  shall have been  effected in the number of
          outstanding shares of the Company's Common Stock, the number of shares
          of  Common  Stock  underlying  this  Warrant  shall be  proportionally
          increased and the cash consideration payable per share of Common Stock
          shall be proportionately reduced; and

               (ii) If a net reduction shall have been effected in the number of
          outstanding shares of the Company's Common Stock, the shares of Common
          Stock underlying this Warrant shall be proportionately reduced and the
          cash  consideration  payable  per  share  of  Common  Stock  shall  be
          proportionately increased.

          (b) In the event of the proposed  dissolution  or  liquidation  of the
     Company,  or any  corporate  separation  or  division,  including,  but not
     limited to, a split-up, split-off or spin-off, or a merger or consolidation
     of the Company with another  company,  or the sale of all or  substantially
     all of the assets of the Company, the Board of Directors of the Company may
     provide  that each holder will have the right to exercise  this Warrant (at
     its then current  Exercise  Price) solely for the kind and amount of shares
     of stock and other securities,  property,  cash or any combination  thereof
     receivable  upon such  dissolution,  liquidation,  corporate  separation or
     division, or merger or consolidation by a holder of the number of shares of
     Common Stock for which this Warrant might have been  exercised  immediately
     prior to such dissolution,  liquidation,  corporate separation or division,
     or merger or consolidation;  or, in the alternative,  the Board may provide
     that this Warrant will terminate as of a date fixed by the Board; provided,
     however that not less than 30 days written notice of the date so fixed must
     be given to the  holder,  who will have the right,  during the period of 30
     days preceding such termination,  to exercise this Warrant as to all or any
     part of the shares of Common Stock covered by this Warrant.

          (c)  The   preceding   paragraph   will  not  apply  to  a  merger  or
     consolidation  in which the Company is the surviving  company and shares of
     Common Stock are not converted  into or exchanged for stock,  securities of
     any other company,  cash or any other thing of value.  Notwithstanding  the
     preceding  sentence,  in case of any  consolidation  or merger  of  another
     company into the Company in which the Company is the surviving  company and
     in which there is a  reclassification  or change (including a change to the
     right to receive  cash or other  property)  of the  shares of Common  Stock
     (excluding a change in par value, or from no par value to par value, or any
     change as a result of a  subdivision  or  combination,  but  including  any
     change in such  shares into two or more  classes or series of shares),  the
     Board may provide  that the holder of this  Warrant  will have the right to
     exercise this Warrant solely for the kind and amount of shares of stock and
     other  securities  (including those of any new direct or indirect parent of
     the Company),  property,  cash or any combination  thereof  receivable upon
     such reclassification, change, consolidation or merger by the holder of the
     number of shares of Common  Stock for which  this  Warrant  might have been
     exercised.

          (d) In the event of a change in the  Common  Stock of the  Company  as
     presently  constituted  into the same number of shares with a different par
     value,  the shares  resulting from any such change will be deemed to be the
     Common Stock of the Company within the meaning of this Warrant.

          (e) Except as expressly provided in this Warrant, the holder will have
     no rights by reason of any subdivision or  consolidation of shares of stock
     of any class, or the payment of any stock dividend or any other increase or
     decrease in the number of shares of stock of any class, or by reason of any
     dissolution, liquidation, merger, or consolidation or spin-off of assets or
     stock of another  company;  and any issue by the Company of shares of stock
     of any class, or securities  convertible into shares of stock of any class,
     will not affect, and no adjustment will be made with respect to, the number
     or price of shares of Common Stock  subject to this  Warrant.  The grant of
     this  Warrant  will not affect in any way the right or power of the Company
     to make adjustments,  reclassifications,  reorganizations or changes of its
     capital or business structures, or to merge or consolidate, or to dissolve,
     liquidate, or sell or transfer all or any part of its business or assets.

     10. All questions  concerning this Warrant will be governed and interpreted
and enforced in accordance  with the internal law, not the law of conflicts,  of
the State of Colorado.

       IN WITNESS WHEREOF,  Cognigen Networks, has caused this Warrant to be signed
by its duly  authorized  officer  and this  Warrant to be dated as of  January  31,
2004.

                             MASTER SERVICES AGREEMENT


This MASTER SERVICES  AGREEMENT (the  "Agreement") is entered into as of the 1st
day of February,  2004,  by and among,  Cognigen  Switching  Technologies,  Inc.
(hereinafter  referred  to as "CST") a  California  corporation  with  principal
offices at Suite 103A, 3220 South Higuera Street, San Luis Obispo, CA 93401, and
Cognigen  Networks,  Inc.  (hereinafter  referred to as  "Cognigen")  a Colorado
Corporation  with its principal  office  located at Suite 210, 7001 Seaview Ave.
NW, Seattle, WA, 98117. CST and COGNIGEN are sometimes referred to herein as the
"Party" or "Parties".

WHEREAS,  CST is the  developer  and owner of computer  programs and  associated
billing  systems  software  and  modules  used  for  telecommunications  rating,
billing, provisioning, customer care, commissioning and database management; and

WHEREAS,  CST, as a wholly owned  subsidiary  of  Cognigen,  has  performed  the
functions of telecommunications  rating, billing,  customer care,  provisioning,
commissioning and database management on behalf of Cognigen in the past, and

WHEREAS,  Cognigen  desires to obtain from CST and CST desires to perform all of
the  aforementioned  functions  going  forward  under the  terms and  conditions
hereinafter set forth;

NOW  THEREFORE,  in  consideration  of the  foregoing  recitals,  of the  mutual
promises,  agreements  and covenants  contained  herein,  and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged by both parties, CST and Cognigen hereby agree as follows:

                                1. Applicable Terms

A. Term

Subject to earlier  termination as provided herein,  this Agreement shall become
effective February 1, 2004, and shall continue in effect for a (12) twelve-month
term. This Agreement shall  automatically be extended for successive twelve (12)
month terms unless  Cognigen or CST shall have provided by certified mail to the
other Party written notice of termination at least thirty (30) days prior to the
expiration of the initial or any subsequent term.

B. Termination

Either Party may terminate this Agreement  because of the other Party's material
breach of the Agreement as set forth in Section 4, below.  Any such  termination
shall not relieve  Cognigen of its  obligation  to pay for  services  previously
performed on its behalf.

                                  C. Early Termination

     i) Cognigen,  at its sole  discretion,  may terminate this Agreement at any
     time prior to the expiration of the then current term upon thirty (30) days
     prior  written  notice.  In the event  Cognigen  chooses to terminate  this
     Agreement  prior to the expiration of the then current term, CST shall make
     every  reasonable  effort to assist Cognigen in successfully  migrating any
     and all services  performed by CST on  Cognigen's  behalf to a  third-party
     vendor of  Cognigen's  choice,  and  continue to provide  such  services on
     Cognigen's behalf until such time the migration is deemed by Cognigen to be
     complete. Cognigen shall continue to pay CST in full for services performed
     on Cognigen's behalf throughout the course of any such migration effort. In
     addition,  Cognigen  shall  pay CST an  amount  equal to two (2)  times the
     average of the two (2) previous month's invoice amounts (Early  Termination
     Fee) upon the completion of the migration.

     ii) CST may terminate  this  agreement in the event that Cognigen  fails to
     timely pay any  amounts  when due under  Section 3 hereof.  In such  event,
     Cognigen shall be deemed to have elected Early Termination.  Cognigen shall
     pay CST an Early Termination Fee as provided in Section 1.C(i) hereof.

2.  Services.  For the term and any  extensions  thereof,  CST hereby  agrees to
provide Cognigen with the following services (collectively "Services"):

     A.   Database management software with the following capabilities:

                |X|   Multi-Market and/or Cycle Database
                |X|   Miscellaneous Code/Rate Plan Maintenance
                |X|   Electronic Invoice Inquiry/Reporting
                |X|   Payment/Adjustment Posting/Reporting
                |X|   Sales Database and Commission Data Structure Maintenance
                |X|   Provisioning for Multiple Carriers
                |X|   Import/Export

     B.   An order-entry  and  administrative  management  software  system that
          allows the establishment and update of account records. In conjunction
          with the account  records,  rate plans,  product  types,  usage rates,
          monthly recurring  charges and other information  necessary to support
          product sales shall be housed in the CST system. The system also shall
          support the functionality necessary to perform new order activations.

     C.   CST will receive, on Cognigen's behalf, carrier usage data directly at
          CST's facility.  CST will receive database  updates,  which are merged
          with carrier usage data, CST's billing programs and, where applicable,
          the taxation database to rate call records and, if applicable, produce
          end-user  invoices.  Printing,  fulfillment  and mailing  services are
          provided at cost for direct  invoices to  end-users.  CST then updates
          its  software  with post  billing  run results  which  import into the
          account database as well as into various reporting engines and updates
          the accounts receivable system.

     D.   CST  shall  make  every  reasonable  effort  to (a)  produce  end user
          invoices (for Direct Billing) within five (5) business days and/or (b)
          produce  Exchange Message  Interface  (`EMI') records within three (3)
          business days and (c) produce all  management  reports within five (5)
          business days from receipt of all components to be incorporated within
          the  billing  run  exclusive  of newly  formed  markets or cycles,  or
          billing runs containing new carrier data or  modifications to existing
          carrier's data. In the event Cognigen  desires to review the output of
          the billing run prior to it being distributed to either the printer or
          the  Local  Exchange   Carrier  (LEC)   clearinghouse,   whichever  is
          applicable,  such time shall be excluded from the  calculation  of the
          number of business days.

     F.   CST  hereby  agrees  to  provide  Cognigen  the  following   services,
          described in greater detail in Exhibits A-1 and A-2 attached hereto:

          i)   Computer  processing  time  as well as  such  CST  personnel,  as
               determined  by  CST,  required  for  the  purposes  of  producing
               end-user   invoices,   provisioning   and  servicing   customers,
               generating      required      reports,      performing      fraud
               detection/resolution  procedures,  and  for  the  support  of the
               Cognigen database software.

          ii)  All  initial  required  programming  and  processing  of  billing
               information  to produce  Cognigen  invoices on  Cognigen  labeled
               stock.  Changes in billing  formats and  subsequent  additions of
               carriers  requiring  program  modifications  may be invoiced on a
               time and materials basis.

          iii) All output files for bill printing in XML or flat-file  format to
               an approved print vendor selected by Cognigen.

          iv)  If applicable  burst,  stuff,  sort, meter, and mail all Cognigen
               invoices.  In the event  Cognigen  has  insufficient  postage  on
               deposit, CST may at its discretion,  return the unposted items to
               Cognigen for Cognigen to disperse.

          v)   Provide file transfer ability of Cognigen data and detail billing
               between the  locations of CST and  Cognigen.  Cognigen  database,
               invoice summary  information and Cognigen  billing detail may, at
               CST's  discretion,  be mailed in electronic  format via overnight
               carrier at Cognigen's  expense or placed in the  Cognigen's  File
               Transfer  Protocol  (`FTP')  directory  for  Cognigen  retrieval.
               Additional charges may apply.

          vi)  Maintain a billing  system  database  with respect to  Cognigen's
               information  including  but not  limited  to,  account  names and
               addresses,  telephone numbers,  rate tables,  transactions posted
               and any monthly charges associated with its customers.

          vii) Provide all management reports created or in the process of being
               created on Cognigen's behalf, in addition to the reports included
               herein as Exhibit A-2.

          viii) Provide Tax Provider's reports.

          ix)  Provide the CogniConference(TM)conferencing product

          x)   Provide switched services (e.g.  CogniDial(TM),  CogniCall(TM)and
               calling cards)

     G. Cognigen agrees to provide CST with the following:

          i)   Call data records in files complete with  Cognigen's  call record
               billing  information  for  CST  processing.  This  call  data  is
               required of all carriers  providing  carrier service to Cognigen.
               CST is not  responsible for errors on call data provided by third
               parties.

          ii)  Legible  record  layouts for all involved  carriers as applicable
               along  with  accompanying   documentation  on  the  data  fields.
               Cognigen shall make every  reasonable  effort to work with CST to
               ensure that periodic  carrier  changes to record  layouts will be
               communicated  to CST in  writing  no less than  thirty  (30) days
               prior to the layout change.

          iii) Cognigen will ensure that its underlying  carriers properly label
               call records and files so as to clearly indicate  Cognigen's name
               on electronic  files and provide a  transmittal  to accompany the
               file clearly identifying the period covered by the tape. CST will
               assume no liability for any  processing  delays or omissions as a
               result of non-labeled or mislabeled tapes or files.

          iv)  Cognigen  will  have  individuals  on  staff  who  have  a  basic
               understanding  of computers and the functions of their  operating
               system.  Questions as to basic operating system functions will be
               billed at CST's  Programmer/Analyst  Support rate as specified in
               Exhibit A-3.

          v)   Cognigen  understands that the integrity of the billing database,
               and,  therefore the accuracy of its billing,  is dependent on the
               relationships  of  its  internal   tables.   Cognigen  shall  not
               intentionally  add,  modify or delete  data  within  the  billing
               database  with any  software  other  than that  supplied  by CST.
               Cognigen  may use other  software  packages to read data from the
               billing  database.  In the event  Cognigen  does  add,  modify or
               delete table entries from the billing  database,  Cognigen  fully
               understands  that CST may not be in a position to assist Cognigen
               in the recovery of its billing  data.  In the event CST can be of
               assistance in  recovering  the billing data, it shall be at CST's
               current  prevailing  rates.  CST shall be held  harmless from any
               losses to Cognigen as a result of Cognigen  modifying its billing
               database and Cognigen  agrees that doing so  constitutes a breach
               of this agreement and CST may terminate  this  agreement  without
               penalty.  In such event  Cognigen  shall be invoiced  under EARLY
               TERMINATION as outlined in Paragraph 1C(i) of this Agreement.

          vi)  Cognigen will give advance written notice to CST of its intent to
               set up a new market and/or cycle.

          vii) Cognigen understands that in order to assure timely processing of
               Cognigen  invoices,  CST  adheres  to  a  strict  job  processing
               schedule. Cognigen shall make reasonable efforts to provide or to
               have  provided to CST any and all necessary  components  for bill
               processing  within a period not to exceed two (2)  business  days
               after the Monthly  Processing  Date. The Monthly  Processing Date
               shall be defined as the  average of the day of the month the last
               carrier call data records to be  incorporated  in the  processing
               run arrives at CST during the first  three (3) months  under this
               Agreement.  Cognigen  shall  make  all  arrangements  to have the
               carrier data sent  directly to CST and to have each type of media
               properly labeled with Cognigen's company name.

3. Service Charges; Payment

     A.   Service Charges. In consideration of the Services,  Cognigen shall pay
          such fees and charges to CST as are  described on Exhibit A-3 attached
          hereto (the "Service Charges").

     B.   Additional  Charges.  Service  Charges are  computed  exclusive of any
          applicable federal, state or local use, excise, gross receipts,  sales
          or other  taxes or similar  charges  ("Additional  Charges"),  whether
          charged  against CST or Cognigen  by reason of the  Services  provided
          hereunder.  Cognigen shall pay all such Additional Charges in addition
          to the Service Charges provided herein.

     C.   Payment. Service Charges are to be payable as follows:

          i)   Service Charges denoted as Set-up Fees on Exhibit A-3 shall start
               accruing February 1, 2004.

          ii)  If incorrect Cognigen information causes a re-run, the greater of
               50% of the  monthly  run cost or $500.00  will be  assessed  as a
               re-run fee.

          iii) During any extension of this  Agreement  beyond its initial term,
               the Monthly  Service Charges shall be those in effect ninety (90)
               days prior to the  expiration of the preceding  term increased by
               up to five (5)  percent.  CST shall give  notice of its intent to
               increase pricing ninety (90) days prior to the end of the initial
               or subsequent terms.

          iv)  Postage  deposits  shall be made one month in  advance.  CST will
               provide a monthly statement showing the  reconciliation of actual
               postage costs versus deposits made by Cognigen.  CST shall notify
               Cognigen   of   inadequate   postage   deposits   and  assume  no
               responsibility  for the delivery of invoices to  Cognigen's  "end
               users" where CST has not received adequate postage deposits.

          v)   If Credit card  accounts  are billed by CST,  funds shall be made
               available to Cognigen  within 3-5 days after the credit card run.
               Cognigen will pay CST its costs  associated with that credit card
               run within ten (10) business days after the credit card run.

          vi)  All other Service Charges, as well as any Additional Charges, are
               payable within thirty (30) days of invoice date.

     D.   Late Payment Charge.  A late payment charge ("Late  Charges") equal to
          the  greater of 1.5% per month (18% per annum) or the  maximum  amount
          allowable by law will be assessed upon any past due invoices.

     E.   Billing  Disputes.  Late Charges shall apply, but shall not be due and
          payable, for any invoice disputed by Cognigen, provided that Cognigen

          (i)  pays all undisputed charges in respect thereof when due,

          (ii) presents  a written  statement  to CST  within a thirty  (30) day
               period   setting  forth  in  reasonable   detail  the  basis  for
               Cognigen's dispute or disagreement, and

          (iii)negotiates  in good faith with CST for the  purpose of  resolving
               such dispute  within a thirty (30) day period.  In the event such
               dispute is resolved in favor of CST,  Cognigen  agrees to pay CST
               the disputed  amount,  together with all applicable Late Charges,
               within  ten (10)  days of  resolution.  In the  event  that  such
               dispute is resolved in favor of Cognigen, Cognigen will receive a
               credit for the  disputed  amount in question  and all  applicable
               Late Charges. CST shall not be obligated to consider any Cognigen
               notice of  billing  disputes  that is  received  by CST more than
               sixty  (60)  days  following  the  due  date  of the  invoice  in
               question.

4. Remedies for Breach.

Except as provided in Section 1.C, in the event  Cognigen or CST is in breach of
this Agreement,  CST or Cognigen may, at CST's or Cognigen's  option,  terminate
this Agreement by written notice to the other.  Cognigen and CST will be granted
a fifteen  (15) day cure period to remedy the breach  upon  receipt of Notice of
Termination. Should Cognigen or CST unreasonably fail to cure said default, this
Agreement shall terminate on the date specified in CST's or Cognigen's Notice of
Termination as if said date were the date specified herein for expiration of the
term of this Agreement. On and after the effective date of such termination, CST
shall  have no  further  obligation  to  render  technical  support  or  service
hereunder.  Termination  of the  Agreement  shall be in  addition  to all  other
remedies available to CST or Cognigen, at law and in equity.

5.    Warranty

CST MAKES NO  REPRESENTATIONS  NOR  WARRANTIES,  EXPRESS OR  IMPLIED,  ABOUT THE
SERVICES  PROVIDED  HEREUNDER,  INCLUDING,  BUT NOT LIMITED TO, ANY  WARRANTY OF
MERCHANTABILITY  OR  FITNESS  FOR A  PARTICULAR  PURPOSE  OR USE OR ANY  IMPLIED
WARRANTY ARISING FROM A COURSE OF DEALING OR COURSE OF PERFORMANCE.

6. Wrongful Acts; General Indemnity; Reimbursement; Limited Liability

     A.   Wrongful  Acts:  Regardless  of the nature of any claim or the form of
          any action which may be brought  against CST as a result of or arising
          out of any errors or omissions  which CST may make or which may result
          from  providing  services  for  Cognigen,  CST's  sole  liability  and
          obligation to Cognigen shall be to use commercially reasonable efforts
          to investigate  and, to the extent  reasonably  practicable and within
          the reasonable  control of CST, correct the circumstances  that caused
          such errors. CST shall not be liable for any loss or damages sustained
          by reason of any failure,  delay or interruption of services  (whether
          or not within the control of CST) covered by this Agreement, nor shall
          CST provide  Cognigen  with any credits to be applied  against  future
          amounts due,  whether such loss or damage arises  because of breakdown
          of equipment, software errors or because of any other reason. Cognigen
          understands  that it shares in the quality control and review process.
          While CST will  apply  its  knowledge  and  experience  to  diligently
          discharge  its  obligations,  no  information  related to the Services
          provided  hereunder will be released from CST's data  processing  shop
          without Cognigen's  approval.  CST's liability hereunder or in any way
          related  to  its  obligations   hereunder  or  the  relationships  and
          transactions   contemplated   hereby   shall   under   no   individual
          circumstances  (whether  based  on  a  contract,   negligence,  strict
          liability  or other  legal or  equitable  theory) be greater  than the
          amount of fees paid by Cognigen for the services with respect to which
          the error or omission  occurred and in the aggregate  shall not exceed
          the amount paid to CST hereunder for the one month period  immediately
          preceding the last event which gave rise to a claim or action.


     B.   General Indemnity:  Cognigen shall forever indemnify and hold harmless
          CST, its Affiliates and their respective officers, members, directors,
          employees and agents,  against and from any and all  liability,  loss,
          damages,  costs and expense  (including  attorneys'  fees and costs of
          litigation)  arising out of or in connection  with any claim or action
          which any person or entity (other than  Cognigen) may file or threaten
          to file against either Party or its officers, directors,  employees or
          agents in any way  relating  to this  Agreement  or the  provision  of
          Services.  The  indemnification  provided  herein  shall  survive  the
          termination  of this  Agreement  and the  termination  of any Services
          provided  pursuant  to  this  Agreement.   Notwithstanding  any  other
          provision  of  this  Agreement,  the  officers,  directors,  managers,
          members,  employees  and  agents of CST  shall  have no  liability  to
          Cognigen,  or any  affiliate of Cognigen,  under this  Agreement or in
          connection with Services to be provided hereunder.

     C.   Reimbursement:  Cognigen  agrees to reimburse  CST for all  reasonable
          costs and expenses  incurred by CST due to CST's direct  participation
          (either as a Party or witness) in any  administrative,  regulatory  or
          criminal  proceeding  concerning Cognigen if CST's involvement in said
          proceeding is based solely on CST's provision of Services to Cognigen.

     D.   Indemnification; Limitations of Liability:

          i)   Cognigen shall  indemnify,  defend and hold CST harmless from and
               against any and all claims, demands, suits, judgments,  losses or
               expenses, including reasonable attorney's fees resulting from any
               act  and/or  omission  of  Cognigen,  its  agents,   servants  or
               representatives  while  engaged in, or in  connection  with,  the
               discharge  or  performance  of  the  obligations  to be  done  or
               performed by Cognigen  hereunder  or otherwise  arising out of or
               related to the transactions contemplated hereby.

          ii)  CST will not be liable for  consequential,  incidental,  special,
               punitive,  exemplary  or  indirect  loss or  damages  of any kind
               arising out of this  Agreement  or  relating to the  transactions
               contemplated  hereby or any  failure to perform  its  obligations
               hereunder  even if CST was  advised  of the  possibility  of such
               damages.  CST will  have no  liability  to  Cognigen  for loss or
               damage to  goodwill or for  revenues  or profits  that might have
               been  generated  or  earned  under  this  Agreement  but  for the
               inability or failure of CST to perform its obligations  hereunder
               or in the event of discontinuation or modification of Services or
               otherwise  in  connection  with  the  transactions   contemplated
               hereby,  nor shall CST have liability for the cost or procurement
               of substitute Services.

          iii) CST will  have no  liability  for  fraudulent  activity  or other
               inappropriate  activities of  End-Users,  nor for the guaranty of
               any checks processed by CST.

          iv)  Cognigen  agrees not to violate any FCC or other federal or state
               rules regarding Cognigen slamming or cramming. Cognigen agrees to
               fully and immediately reimburse, CST and the employees, officers,
               directors,  partners,   shareholders,   successors,  assigns  and
               independent   contractors  of  CST,  for  all  claims,   damages,
               liabilities  or expense  of any  description  (including  but not
               limited to reasonable  attorneys  fees and costs)  arising out of
               the violation by Cognigen or any of Cognigen's employees,  agents
               or  representatives  of any  applicable  FCC and/or  state  rules
               regarding Cognigen slamming or cramming.  Cognigen further agrees
               that  Cognigen  will not settle any such dispute or claim without
               consulting  with CST and obtaining  CST's prior written  consent.
               Cognigen must also allow CST to participate in its own defense at
               Cognigen's expense.

          v)   Cognigen shall be solely and singularly  responsible  for payment
               of any  commissions  or  other  compensation  owed to  Cognigen's
               employees,  agents or  representatives.  Nothing contained herein
               shall be construed to create any  obligation by CST whatsoever to
               pay  commissions  or  other  compensation  to any  of  Cognigen's
               employees,  agents or  representatives.  Cognigen shall indemnify
               and hold  harmless CST from and against any and all claims by any
               of Cognigen's employees, agents or representatives for payment of
               commissions or other compensation.

          vi)  CST shall indemnify,  defend and hold Cognigen  harmless from and
               against any and all claims, demands, suits, judgments,  losses or
               expenses, including reasonable attorney's fees resulting from any
               act  and/or   omission   of  CST,   its   agents,   servants   or
               representatives  while  engaged in, or in  connection  with,  the
               discharge  or  performance  of  the  obligations  to be  done  or
               performed by CST hereunder or otherwise arising out of or related
               to the transactions completed hereby.

          vii) Cognigen  will  not  be  liable  for  consequential,  incidental,
               special,  punitive,  exemplary or indirect loss or damages or any
               kind   arising  out  of  this   Agreement   or  relating  to  the
               transactions  contemplated  hereby or any  failure to perform its
               obligations  hereunder  even  if  Cognigen  was  advised  of  the
               possibility  of such damages.  Cognigen will have no liability to
               CST for loss or damage to  goodwill  or for  revenues  or profits
               that might have been generated or earned under this Agreement but
               for  the   inability  or  failure  of  Cognigen  to  perform  its
               obligations  hereunder  or in the  event  of  discontinuation  or
               modification  of services or  otherwise  in  connection  with the
               transactions  contemplated  hereby,  nor shall CST have liability
               for the cost or procurement of substitute services.


7. Alternative Dispute Resolution

     A.   Arbitration.  In the event of any  dispute or claim  arising out of or
          relating to this Agreement,  or the breach thereof,  the Parties agree
          that each shall discuss and negotiate the issues  between the Parties'
          authorized  agents,  with  informal  escalation  within  the  Parties'
          organizations  as  necessary  to  pursue  and  achieve  resolution  as
          expeditiously  as  possible.  If a  resolution  cannot be  arrived  at
          between the Parties through informal  negotiations as described above,
          either Party may serve written notice upon the other that negotiations
          have reached an impasse.  After  written  notice of impasse is served,
          either Party may, within sixty (60) days after service of this notice,
          serve  upon the other  written  demand  that the  dispute  or claim be
          submitted  to  arbitration.  Said demand shall set forth the nature of
          the dispute or claim, an approximation  of the amount in question,  if
          any, and the nature of the remedy  sought.  The dispute or claim shall
          be submitted to arbitration  administered by the American  Arbitration
          Association ("AAA"), or any successor organization, under AAA's or any
          successor  organization's rules for commercial  arbitration.  Judgment
          upon an award  rendered  by the  arbitrator(s)  may be  entered in any
          court having jurisdiction  thereof.  The place of arbitration shall be
          San Luis Obispo, California.

     B.   Authorized  Agent.  In the  absence of express  written  notice to the
          contrary,  each Party's  authorized agent for purposes of this Section
          10 herein shall be deemed to be each Party's representative whose name
          appears as a signatory  to this  Agreement,  or the  successor of such
          person.


8. Force Majeure

If CST's or Cognigen's performance of this Agreement or any obligation hereunder
is  prevented,  restricted or  interfered  with by causes beyond its  reasonable
control  including,  but not limited to, acts of God, acts of  terrorism,  fire,
explosion,  vandalism,  loss of  electrical  power,  cable  cut,  storm or other
similar occurrence, any law, order, regulation,  direction, action or request of
the  United  States  government  or any  foreign  government,  or state or local
governments,   or  of  any  department,   agency,  commission,   court,  bureau,
corporation or other instrumentality of any one or more such governments,  or of
any civil or military authority, or by national emergency,  insurrection,  riot,
war, strike,  lockout or work stoppage or other labor difficulties,  or supplier
failure,  shortage,  breach or delay, then CST or Cognigen shall be excused from
such  performance  on a day-to-day  basis to the extent of such  restriction  or
interference.   CST  or  Cognigen  shall  use   reasonable   efforts  under  the
circumstances to avoid or remove such causes or nonperformance and shall proceed
to perform with reasonable dispatch whenever such causes are removed or cease.

10.   No-Waiver

No term or provision of this  Agreement  shall be deemed waived and no breach or
default  shall be deemed  excused  unless  such  waiver or  consent  shall be in
writing and signed by the Party claimed to have waived or  consented.  A consent
to waiver of or excuse for a breach or default by either Party,  whether express
or implied,  shall not  constitute  a consent  to,  waiver of, or excuse for any
different or subsequent breach or default.

11.   Partial Invalidity; Government Action

     A.   Partial Invalidity:  If any part of any provision of this Agreement or
          any other  agreement,  document  or writing  given  pursuant  to or in
          connection with this Agreement shall be invalid or unenforceable under
          applicable law, rule or regulation,  that part shall be ineffective to
          the extent of such invalidity  only,  without in any way affecting the
          remaining parts of that provision or the remaining  provisions of this
          Agreement.  In such event,  Cognigen  and CST will  negotiate  in good
          faith with  respect to any such invalid or  unenforceable  part to the
          extent necessary to render such part valid and enforceable.

     B.   Exclusive  Remedies.  Except as  otherwise  specifically  provided for
          herein,  the  remedies  set  forth  in  this  Agreement  comprise  the
          exclusive remedies available to either Party at law or in equity.

12.   Choice of Law Forum

     A.   Law: This Agreement  shall be construed under the laws of the State of
          California without regard to choice of law principles.

     B.   Forum:  Any legal action or proceeding  with respect to this Agreement

          County of San Luis Obispo, California. By execution of this Agreement,
          both  Cognigen  and CST  hereby  submit to such  jurisdiction,  hereby
          expressly  waiving whatever rights may correspond to either of them by
          reason of their  present or future  domicile.  In  furtherance  of the
          foregoing,  Cognigen and CST hereby  agree to service by U.S.  Mail at
          the notice addresses referenced in Section 9.

13.   Confidential Information; Non-Solicitation

     A.   Any specifications,  drawings,  sketches,  models,  lists,  proposals,

          or otherwise (all hereinafter designated Information) furnished by the
          Parties to one  another  hereunder  shall  remain the  property of the

          supplier of such  Information upon request or upon termination of this
          Agreement.

Agents' Brand Management Web Site
 This web site will be made available to ALL agents for the purposes of managing
 accounts and assisting in customer service, collection and provisioning issues.
 Many agents are hands on and prefer to be involved with their accounts care and
 feeding. This web site allows the agent to do the following.
      View all accounts under the brand by:
|_|   accounts sent to carrier and carrier PIC status
|_|   closed accounts and reason code for close
|_|   aging report showing current, 30,60,90,120 accounts
      View action item report that shows the highest priority action items that
      the agent must      attend to and collection and provisioning issues
      View and add notes to accounts

Customer service Subscriber activation system
 This web site is used by internal customer service to:
|_|   View all new and pending orders by product brand
|_|   Identify all VERIFIED orders
|_|   Send email and phone communications to customers that require forms or more
         information
|_|   Perform EquiFax credit checks and send to provisioning system
|_|   Abandon orders for over 20 reasons and note accounts

Provisioning system
|_|   This system accepts verified orders and determines which carrier to send
         the order to based on customized carrier PIC business rules developed
         for each product.
|_|   The daily care (TCSI) and call detail is used to determine the status of a
         line or toll free number.  Automated email messages are sent out for
         customer required action or successful line or toll free number switch.
|_|   Automatic resubmit of orders is performed when no care has been received
         for line or toll free number within 3 days.  Most of the time some kind
         of care is received with 24 hours.  This system was developed when it
         was found that our carriers sometimes manage to "drop" order lines.
         This sweeping action has resurrected many orders.
|_|   Automated action item emails to carrier account managers:
         There are many instances when the carrier procedures require that an
         actual email is sent to the account manager as a work order so that a
         line can be added to our - Cognigen's carrier account.  This system
         detects which email, carrier and account manager to send the message
         to.  Also, it receives the email reply and automatically processes the
         result and performs the resubmit or account status change, etc.

Dial-Around, Calling Card and Conference System
 CST has integrated Cognigen's 1 plus product with CST's existing conferencing,
international calling card and dial-around platform.  All calls made on this
system appear on the same single 1 plus invoice.  The customer can manage all of
