(b)  Licensee is current on all payments due under prior Site License Agreements
for  all  Licensed  Facilities  under  this  Agreement  in accordance with their
respective  terms;
(c)  there  is not a material default under this Agreement for which Licensee is
responsible  resulting  from  or  affecting  more  than  one Licensed Plant; and
(d)  no Person having a Participating Interest in the proposed Licensed Plant is
in  material  default  under  any  agreement  relating  to  Licensor Technology.

Until  such  time  as the above conditions are satisfied, Licensee shall have no
right  or  license  to  use  Licensor Technology at the proposed Licensed Plant.

2.06     During  the  term of this Agreement, Licensee may extend this Agreement
to  any Affiliate, provided that Licensee shall first notify Licensor in writing
of  any  such  extension  and the acceptance of such extension by such Affiliate
pursuant  to  this  Section  2.06.  The Affiliate to which this Agreement may be
extended  by  Licensee  shall  be subject to and shall accept in writing (in the
form  set  forth  in  Attachment  2)  the  same obligations to which Licensee is
subjected  under  this  Agreement and all terms and conditions of this Agreement
shall  apply  to  such  Affiliate with respect to its obligations and its rights
(except  the  right  of  extension as set forth in this Section 2.06) as if such
Affiliate had entered into this Agreement with Licensor effective as of the date
of  such  extension.  Licensee warrants to Licensor the full performance by such
Affiliate  of  the obligations which are imposed upon such Affiliate as a result
of  such  extension  of  this Agreement and, notwithstanding any such extension,
Licensee  shall  still  be liable to Licensor for all sums which become due from
such  Affiliate  to  Licensor  and  for  any  default  by  such Affiliate in the
performance  of  its  obligations  under  this  Agreement.

2.07     Each  Licensed  Plant  shall  remain  at  the  initial plant site for a
minimum  of  seven  (7)  years  from  Start-Up  Date.  Thereafter,  Licensee may
relocate  a  Licensed  Plant  to  a new plant site within the Licensed Territory
without  obtaining  a new Site License Agreement provided (i) request is made by
Licensee  to  Licensor in the form of Exhibit G of the Site License Agreement in
which  Licensee  agrees  that the Licensed Plant will remain at the new site for
minimum  of  seven  (7)  years and (ii) the Licensee is not in default under the
Site  License  Agreement for the Licensed Plant.  Notwithstanding the foregoing,
Licensed  Plants  utilizing  gas from leases, concessions, or similar production
sharing  arrangements  in  which  Licensee  or its Affiliates own at least a ten
percent  (10%)  working,  net  profits,  equity,  or  other  economic  interest
(excluding  any  interest  owned  by a governmental entity) may, at any time, be
relocated  within  the geographic boundaries of any such leases, concessions, or
similar  production  sharing  arrangements.  Nothing  in  this  Agreement  shall

EXEMPLARY  DAMAGES,  INCLUDING  WITHOUT  LIMITATION,  LOST  PROFITS  OR SAVINGS,
REGARDLESS  OF  THE FORM OF ACTION GIVING RISE TO SUCH A CLAIM FOR SUCH DAMAGES,
WHETHER  IN  CONTRACT OR TORT INCLUDING NEGLIGENCE, EVEN IF LICENSOR OR LICENSEE
HAS  BEEN  ADVISED  OF THE POSSIBILITY OF SUCH DAMAGES.  BUT IF A PARTY IS FOUND
LIABLE,  DESPITE  THE  ABOVE LANGUAGE, TO THE OTHER PARTY FOR SPECIAL, INDIRECT,
CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR EXEMPLARY DAMAGES THEN THE MAXIMUM LIMIT
OF  SUCH  DAMAGES  IS  AGREED  TO  BE  $5,000.

6.05     A  Party  will  promptly advise the other Party in writing of any claim
made  or  lawsuit  alleging  infringement  of  any  patent  or  copyright  or
misappropriation  of  Confidential Information based on the design, construction
and/or  operation  of  Licensed  Facilities  (including  Synthetic  Product  or
Marketable  Products  produced  from  Licensed  Facilities).

     (a)  If  Licensee  has  made  a modification to the Process Design Package,
with  respect  to a Licensed Plant, and infringement or misappropriation by such
Licensed  Plant  would  not  exist  in  the  absence of Licensee's modification,
Licensee  will be solely responsible for any claim or lawsuit. Licensee will (i)
promptly  undertake  at its own expense the defense of the claim or lawsuit, and
(ii) hold Licensor, its Affiliates, and their officers, directors, and employees
harmless  from  any liability, damages and other sums that may be assessed in or
become payable under any decree or judgment by any court or other tribunal which
results  from  such  claim  or  lawsuit  and  from  any attorneys fees, costs of
litigation  and  other reasonable out of pocket expenses incurred in the defense
of  such  claim  or  lawsuit.

     (b)  If the design, construction and/or operation of a Licensed Plant which
is the basis for alleged infringement or misappropriation, is in accordance with
the designs, specifications and operating conditions (including, but not limited
to,  catalysts)  embodied in the Process Design Package for such Licensed Plant,
Licensor will (i) promptly undertake at its own expense the defense of the claim
or  lawsuit,  and  (ii)  hold  Licensee,  its  Affiliates,  and  their officers,
directors,  and  employees  harmless  from any liability, damages and other sums

misappropriation  and  such Party shall have the right to be represented therein
by  advisory  counsel  of  its  selection  and  at  its  expense.

     (d)  In  the event a court or other tribunal finds that infringement and/or
misappropriation  has  occurred  not  as  a  result of Licensee's modifications,
Licensor  shall  have  the  option,  at  its sole expense, to either (i) provide
designs,  specifications and/or operating conditions (including, but not limited
to,  catalysts)  and  make  modifications to the Licensed Plant which avoid such
infringement  and/or  misappropriation  without  degrading  the  economics  or
performance  of  the  Licensed Facilities, or (ii) acquire the right to continue
using  the  design,  construction  and  operating conditions (including, but not
limited  to,  catalysts),  which  were  the subject of such  infringement and/or
misappropriation.

     (e) Except as provided in (d) above, a Party shall not settle or compromise
any  claim  or  lawsuit  alleging  infringement  or misappropriation without the
written  consent  of  the other Party if such settlement or compromise obligates
the  other  Party  to  make any payment or part with any property, to assume any
obligation  or  grant  any  licenses  or  other  rights, or to be subject to any
injunction  by  reason  of  such  settlement  or  compromise.

Affiliates,  and  their  officers, directors, and employees from and against the
full  amount  of  any  and all claims, demands, actions, damages, losses, costs,
expenses,  or  liability  whatsoever  (including without limitation the costs of

                       7.  CONFIDENTIALITY AND LIMITATIONS
                       -----------------------------------

7.01     Licensee agrees that any Confidential Information disclosed by Licensor
or  an  Affiliate  directly or indirectly to Licensee during the period from the
date  of  Licensee's execution of the Confidentiality Agreement through the term
of this Agreement, will be kept confidential by Licensee for a period of fifteen
(15)  years  after the date of each disclosure, but not to exceed five (5) years
after the termination of this Agreement or fifteen (15) years from the Effective
Date,  whichever  last  occurs,  with the same standard of care Licensee uses to
protect  its  own  similar  confidential  information  and,  except as otherwise
provided  in  this  Agreement,  will  not  be  disclosed  to others or copied or
duplicated  (except for internal use), and will be used by Licensee solely as it
relates  to  this  Agreement,  and  for  no  other purpose, including Licensee's
research, development or commercial activities related to the Conversion Process
for  its  own  account.  Licensee  may disclose such Confidential Information to
third  parties  who  have  executed  a  secrecy  agreement  with  Licensor  with
confidentiality  terms  no less restrictive than those set forth in this Section

7.01.  To  the  extent  reasonably  necessary  to carry out the purposes of this
Agreement,  Licensee  may  disclose  any  of  the  foregoing  information  to an
Affiliate, provided that the Affiliate has agreed in writing to be bound by this
Agreement.

7.02     Licensor agrees that any Confidential Information disclosed by Licensee
or  an  Affiliate  directly  or  indirectly  to Licensor during the term of this
Agreement  will  be  kept  confidential by Licensor for a period of fifteen (15)
years  after the date of each disclosure, but not to exceed five (5) years after
the termination of this Agreement or fifteen (15) years from the Effective Date,
whichever  last  occurs, with the same standard of care Licensor uses to protect
its  own  similar  confidential information, and except as otherwise provided in
this Agreement will not be disclosed to others or copied or duplicated, and will
be  used  by  Licensor solely in the development, marketing and licensing of the
Conversion  Process,  and  for  no  other  purpose.  Licensor  may disclose such
Confidential  Information to third parties who have executed a secrecy agreement
with  confidentiality  terms  similar  to the confidentiality provisions of this
Agreement.  To the extent reasonably necessary to carry out the purposes of this
Agreement,  Licensor  may  disclose  any  of  the  foregoing  information  to an
Affiliate,  provided that the Affiliate has agreed in writing to be bound by the
relevant  provisions  of  this  Agreement.

7.03     A  Party shall not be subject to the restrictions set forth in Sections
7.01 and 7.02 as to the disclosure, duplication or use of disclosed Confidential
Information,  which  the receiving Party can prove by competent evidence (a) was
already  known  to  the  receiving Party or an Affiliate prior to the disclosure
thereof  by the disclosing Party; (b) is or becomes part of the public knowledge
or  literature  without breach of this Agreement by the receiving Party but only
after it becomes part of the public knowledge or literature; (c) shall otherwise
lawfully  become  available  to the receiving Party or an Affiliate from a third
party but only after it becomes so available and provided the third party is not
under  obligation of confidentiality to disclosing Party; or (d) is developed by
the  receiving  Party  or  an  Affiliate  independently of any disclosure by the
disclosing  Party to the receiving Party or an Affiliate under this Agreement or
independently  of  any joint research and development activities of Licensee and
Licensor  which  may  occur  under  a  separate  agreement.  Any  Confidential
Information  disclosed  shall  not  be deemed to fall within the confidentiality
exceptions  of  this  Section 7.03 merely because it is embraced by more general
information.  In  any such case set forth in Section 7.03(a), (b), (c), and (d),
the  receiving Party shall keep confidential and not disclose to any third party
that  any  such  information  was  also  made  available  to  or acquired by the
receiving Party or an Affiliate from the disclosing Party, and such release from
the  secrecy  obligation shall not be considered as a license to make, sell, use
or  operate  under  any  of  the  disclosing  Party's  proprietary  rights.

7.04     The  receiving Party shall limit access to the Confidential Information
disclosed  to  it  to those employees of the receiving Party or an Affiliate who
reasonably  require  the  same  and  who  are  under  a  legal  obligation  of
confidentiality  on  the  terms set forth in Section 7.01 and Section 7.03.  The
receiving Party shall be responsible to the disclosing Party for the performance
by  its  employees  of  their  confidentiality obligations.  The receiving Party
shall  keep a record of any Confidential Information marked "Limited Access" and
the  identity  of  each  employee  who has access to Confidential Information so
marked.  The  receiving  Party  shall  inform the other Party of the identity of
each  such  employee  within  30  days  of  disclosure.

7.05     In  the  event  that  a  Party  which  is  recipient  of  Confidential
Information  from  the  other  Party  is  requested  or  required by deposition,
interrogatory,  request  for  documents, subpoena, civil investigative demand or
similar  process  to  disclose any such  Confidential Information, the receiving
Party  shall  provide  the  disclosing  Party with prompt written notice of such
request  or  requirement  prior  to  making  the requested disclosure, and shall
cooperate  with  the  disclosing  Party  so that the disclosing Party may seek a
protective  order  or  other  appropriate  remedy or, if the disclosing Party so
elects,  waive  compliance  with  the terms of this Agreement. In the event that
such  protective order or other remedy is not obtained, the receiving Party  may
disclose  only that portion of the Confidential Information which the disclosing
Party  is  advised  by  counsel  is  legally  required  to  be  disclosed.

7.06     The  Parties agree that they will each take all actions and execute all
documents,  and  shall cause their employees, agents and contractors to take all
actions  and  execute all documents as are necessary or appropriate to carry out
the  provisions of this Article 7 or to assist each other in securing protection
of intellectual property and Confidential Information referenced in this Article
7.

7.07     With  respect to any catalyst furnished by Licensor to Licensee for use
by Licensee at the Licensed Facilities, Licensee will not, and Licensee will not
allow  any  other  person to, analyze, break down, reverse engineer or otherwise
seek to determine the chemical composition, except for loss on ignition and bulk
density,  of  any  such  catalyst, except that Licensee shall be entitled to (a)
perform  analyses  that Licensor may from time to time specifically authorize in
writing,  to  the extent required for monitoring the performance of the Licensed
Facilities  and  for  regeneration,  reclamation or disposal of spent catalysts,
such  authorization  not to be unreasonably withheld, and (b) provide results of
the  aforementioned  analyses  to  other  parties  to  the  extent  required for
regeneration,  reclamation  or  disposal of spent catalysts, but only after such
other  parties  have  entered into an agreement with Licensor in a form attached
hereto  as  Exhibit  E of the attached Site License Agreement.  Licensor will be
provided  with  a  copy  of all such analyses which has been approved in writing
prior  to  release  to  other  parties.

                          8.  ASSIGNMENT AND TRANSFERS
                          ----------------------------

8.01     Except  for assignment to an Affiliate or the successor in interest, by
purchase  or  otherwise,  of  Licensee  (but  specifically  excluding  Exxon
Corporation,  Royal  Dutch Shell, Sasol Limited or any entity in which they have
an equity interest), which may be made without written consent of Licensor, this
Agreement  shall not be assignable by Licensee without the prior written consent
of the Licensor, which consent will not be unreasonably withheld.  Licensee will
promptly  notify  Licensor in writing of any assignment to an Affiliate, or such
successor  in interest. Except for assignment to an Affiliate, or such successor
in  interest,  any  attempted  assignment  of this Agreement by Licensee without
consent  of  Licensor  shall  be  void.

8.02     In  the  event  of  the  transfer  of  all  or  a portion of Licensee's
Participating  Interest  in  any  Licensed Plant to another Person other than an
Affiliate,  Licensee  shall  obtain such Person's unconditional execution of the
Site  License  Transfer  Letter  set  forth  in  Exhibit  F  of the Site License
Agreement,  and  submit such Letter to Licensor, whereupon if Licensor gives its
written  consent, such consent not to be unreasonably withheld, then such Person
to  whom  such  Site  License  Agreement  shall  have  been transferred shall be
substituted  for  Licensee  for  all  purposes  in connection with such Licensed
Plant.  Licensor's  refusal to consent may be justified by Licensor's reasonable
concern  that  assignee  will  not  comply  with the terms of this Agreement.  A
transfer  of  Licensee's Participating Interest does not relieve Licensee of its
confidentiality  obligations  under  this Agreement with respect to Confidential
Information  associated  with  such  transferred  Participating  Interest.

                            9.  TERM AND TERMINATION
                            ------------------------

9.01     This  Agreement  shall  extend  for  a  period  of  fifteen  (15) years
following  the Effective Date, or five (5) years following the effective date of
the  last  Site  License  Agreement  issued under this Agreement, whichever last
occurs.

9.02     Upon  the  written  notice  from  Licensor  to Licensee of any material
default  under  this  Agreement  (including  any  material  default under a Site
License  Agreement),  other  than  as  noted  in Section 2.05 (c), all rights of
Licensee  under  Section  2.05 of this Agreement,  shall be suspended until such
default is cured by Licensee.  Licensee's or an Affiliate's right to operate any
Licensed  Plant which is in compliance with its Site License Agreement shall not
be  affected by either a default under this Agreement or a default under another
Site  License  Agreement for another Licensed Plant. If a material default under
this  Agreement shall continue for a period of one year following written notice
of  such default to Licensee from Licensor without being cured by Licensee, then
Licensor  shall  have the right to (a) suspend all rights of Licensee under this
Agreement, or (b) terminate this Agreement upon written notice to Licensee.  The
actions  by  Licensor  under this Section 9.02 shall not prejudice Licensor from
enforcing any claim which it may have for damages or otherwise on account of the
default.

9.03     Termination  of  this  Agreement  shall  not:
(a)     relieve  Licensee  of its obligations to account for and pay all amounts
due  Licensor  under  this Agreement and all Site License Agreements executed by
Licensee  under  this  Agreement;
(b)     affect  any  rights  granted  Licensee  under Site License Agreements in

                               ------------------

10.01       This  Agreement embodies the entire intent of the Parties and merges
all prior oral and written agreements between the Parties hereto with respect to
subject  matter  hereof.  No  stipulation,  agreement,  representation  or
understanding  of  the  Parties  hereto  shall  be  valid  or enforceable unless
contained  in  this Agreement or in a subsequent written agreement signed by the
Parties  hereto.  In  the  event of a conflict between this Agreement and a Site
License  Agreement  executed  pursuant  to  this  Agreement, this Agreement will
govern.

10.02     THIS  AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE  LAWS  OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA, WITHOUT REGARD TO
CONFLICT  OF  LAW  PROVISIONS  THEREOF.  The  Parties  expressly and irrevocably
consent and submit to the jurisdiction of any federal court sitting in the state
of  Oklahoma  and  agree  that,  to the fullest extent allowed by law, only such
Oklahoma federal courts, to the exclusion of all others, shall have jurisdiction
over  any  action,  suit  or  proceeding  arising  out  of  or  relating to this
Agreement.  Provided,  however,  that  in the event that no federal court in the

any  action,  suit, or proceeding, the Parties expressly and irrevocably consent
and  submit  to  the  jurisdiction  of  any  state court sitting in the state of
Oklahoma  and  agree  that,  to  the  fullest  extent  allowed by law, only such
Oklahoma  state  courts, to the exclusion of all others, shall have jurisdiction
over  any  such  action,  suit  or proceeding arising out of or relating to this
Agreement.  The Parties each irrevocably waive, to the fullest extent allowed by
law,  any  objection  either of them may have to the laying of venue of any such
suit, action or proceeding brought in any state or federal court sitting in, the
state  of  Oklahoma  based  upon  a  claim  that  such  court is inconvenient or
otherwise an objectionable forum.  Any process in any action, suit or proceeding
arising out of or relating to this Agreement may, among other methods, be served
upon  any Party by delivering it or mailing it to their respective addresses set
forth  herein.  Any  such  delivery  or mail service shall be deemed to have the
same  force  and  effect  as  personal  service  in  the  State  of  Oklahoma.

10.03     This  Agreement  does not grant and shall not be construed as granting
any  license,  authorization  or  consent,  to  either  Party by the other Party
hereto,  to  use any name, trademark, service mark or slogan of the other Party.
A Party shall not use the other Party's name without written consent, except for
the  identification  of  the  other  Party as a Licensee or Licensor of Licensor
Technology.  The  terms  of  this  Agreement will be maintained in confidence by
each  Party  subject to the same standard of care each Party uses to protect its
confidential  information,  except  as  required  by law.  A press release which
includes  the  name  of  the other Party must have prior written approval of the
other  Party,  except  as  required  by  law.

10.04     Failure  of  either  Licensor  or Licensee at any time or from time to
time to exercise any of its rights under this Agreement or to insist upon strict
performance  of  the  other  Party's obligations hereunder shall not be deemed a
waiver  of  or  to  limit any of such rights or obligations with respect to such
rights  or  obligations  or  any  subsequent  occurrence.

10.05     Licensee may publish the existence of this Agreement but agrees not to
disclose,  without the written consent of the Licensor, any of the terms of this
Agreement  or  any portion thereof, or any amendment concerning the same, except
to  Persons directly involved with design, financing, construction, or operation
of  a  Licensed  Plant  on  a  need-to-know  basis  or  as  required  by  law.

10.06     Licensee  agrees  that  all Licensor information, technology, patents,
and  the  product  produced  directly  by the use thereof, when used outside the
United States of America, shall be used by Licensee subject to and in accordance
with regulations of any department or agency of the United States of America and
Licensee shall not re-export or transship or agree to re-export or transship any
such  Licensor  information,  technology,  patents,  and  the  product  produced
directly  by  the use thereof to any destination prohibited by United States law
including, without limitation, United States executive orders and administrative
orders,  rules,  and regulations or to any destination requiring the approval of
the  United  States  government for such re-exportation or transshipment until a
request  to  do  so  has  been  submitted  to  and approved by the United States
government  and notice of such approval has been provided to Licensor.  Licensee
shall  not  (i)  enter  into  a  transaction  or  dealing,  including,  without
limitation,  re-exporting  the  Licensed  Technology,  or  causing,  financing,
guaranteeing,  authorizing or facilitating an action to enter into a transaction
or dealing, that might reasonably be considered a violation of United States law
by either Licensor or Licensee, or (ii) disclose information in a way that might
reasonably  be considered a violation of United States law by either Licensor or
Licensee.

10.07     Should  any  part or provision of this Agreement be held unenforceable
or  in  conflict with the law of any state or of the United States of America or
of  any foreign country, the validity of the remaining parts or provisions shall
not  be  affected  by  such  holding.

                             -----------------------

I.     For  purposes  of  this  Attachment 3, the following terms shall have the
meanings  ascribed  thereto:

A.     "LICENSED  PLANT"  means  the  Licensed  Plant  in  which  a Site License
Agreement  for  such  plant is issued to and remains in the name of the Licensee
who  has  executed  this Agreement with Licensor and, in which the Participating
Interest  held by Licensee, or collectively by Licensee and any other Person who
has  executed  a  license  agreement (which is applicable to the Licensed Plant)
with  Licensor, represents at least 10% of the entire Participating Interest not
held  by  a  governmental  authority  regardless of operatorship of the Licensed
Plant.

B.     "ROYALTY  RATE"  shall  mean  (i)  the  lowest royalty rate per Barrel of
Synthetic  Product  accepted  by  Licensor  for  a Site License Agreement with a
non-Affiliate  for  a  facility  of  comparable size, in the Licensed Territory,
which  is not under a master preferred license agreement, during the twelve (12)
months  immediately  preceding the execution date of the applicable Site License
Agreement  under  this  Agreement, or (ii) if no such Site License Agreement has
been  executed  during  the  twelve  (12) months immediately preceding, then the
royalty  rate per Barrel of Synthetic Product in the last Site License Agreement
with  a non-Affiliate, in the Licensed Territory, executed by Licensor, which is
not  under  a  master  preferred  license  agreement,  or  (iii)  if none of the
foregoing  applies,  then  US$______  per  Barrel  of Synthetic Product.  Market
Royalty  Rate  does not include the catalyst price as provided for under Section
                                                                         -------
2.03  of  this  Agreement.
 ---

II.  For  each  Site  License  Agreement executed for Licensed Plants under this
Agreement,  Licensee agrees to pay License Fees to Licensor on a prepaid license
basis  as  follows:

A.     Licensee  agrees  to  pay  Licensor  a  one-time,  prepaid  License  Fee
calculated  in  accordance  with  the  following  formula:

License  Fee  =  "C"  x  350  x  7.5  x  "R"

<PAGE>
wherein:

"C"  =     the  maximum  daily design capacity, as defined by the Process Design
Package,  of  such  Licensed  Plant  to  produce Marketable Products measured in
Barrels of Synthetic Product per day for which such Licensed Plant is originally
designed  and  constructed,  and
"R"  =  the  Royalty  Rate.

and  payable  in  installments  as  follows:

(i)     20%  within  thirty  (30)  days  after the execution of the Site License
Agreement  for  such  Licensed  Plant;

(ii)     30%  within  thirty  (30)  days  after  delivery  of the Process Design
Package  or within one hundred twenty (120) days after the execution of the Site
License  Agreement  for  such  Licensed  Plant,  whichever  first  occurs;

(iii)     20%  within  thirty  (30)  days  after  the  commencement  of  field
construction  move-in;

(iv)     30% within one-hundred and twenty (120) days after the Start-Up Date of
the  Licensed Plant or a successful Performance Test as specified in the Process
Guarantee  and  Performance  Test  Agreement,  whichever  first  occurs.

B.  Capacity  Adjustments:  In  the  event the actual production capacity of any
Licensed  Plant,  under  II.A.  above, is determined to have either exceeded the
original maximum daily design capacity established in its Site License Agreement
or  is increased through major equipment modification, by more than five percent
(5%)  or  by more than 500 barrels per day, at any time after the Start-up Date,
Licensee shall pay Licensor an additional License Fee, on a prepaid basis, equal
to  the  difference  between  (a)  the  prepaid  License  Fee as would have been
calculated  with  the  higher  production  capacity  for  such  Licensed  Plant
substituted  for "C" in the calculation method set forth in II.A. above, and (b)
the  License  Fee  as  would have been calculated for such Licensed Plant by the
method set forth in II.A. above using the original maximum daily design capacity
established  in  each  Site  License Agreement.  The incremental License Fee due
will  be  reduced  by  any  previous  incremental  adjustments.  Such additional
License  Fee  shall  be  payable  within  thirty  (30) days after the end of the
calendar  year  in  which  such increase in production capacity of such Licensed
Plant occurs.  Incremental License Fees for increased production capacity in any
Licensed  Plant  shall  not  be  due if the increased production capacity is the
result  of  the  initial  use  of  Licensee  Patent Rights or Licensee Technical
information.  The  total  cumulative incremental capacity adjustments under each
Site  License  Agreement  will  be  limited to 50 percent of the initial maximum
daily  capacity  under  such  Agreement.

III.     Upon  payment of all fees due under the Site License Agreement for each
Licensed  Plant,  Licensee shall be deemed to have acquired a fully paid license
for  such Licensed Plant up to the original maximum daily design capacity or any
adjusted  daily  design  capacity made under the provisions of II.B. above.  Any
additional  incremental increases in the Licensed Plant capacity will be subject
to  additional  License Fees as calculated under Incremental Adjustments defined
under  II.  above.

IV.     All  payments  required  hereunder shall include a statement showing the
details  supporting  the  calculation  of the License Fees being paid.  Licensee
shall  keep accurate and complete records of all natural gas feedstock processed
(volume  and  composition) and all Synthetic Product produced at and either used
internally  within or removed from each Licensed Plant to enable verification of
statements  and  payments  rendered  to  Licensor hereunder.  Licensee agrees to
permit  Licensor,  at Licensor's expense,  to inspect such records on reasonable
notice  and  at  reasonable intervals during normal business hours to verify the
fees  paid  and  payable  under  this  Agreement.<PAGE>

          (a) From InfoSpace Executive shall be granted two non-qualified stock
options to purchase an aggregate of 3,500,000 shares of the common stock of
InfoSpace, such number of shares to be adjusted pursuant to the terms of the
March 15, 2000 stock split (or any subsequent stock split).  One of the stock
options shall be in the amount of 1,000,000 (pre-split) shares of the common
stock of InfoSpace (the "InfoSpace Option").  The other stock option shall be in
the amount of 2,500,000 (pre-split) shares of the common stock of InfoSpace (the
"InfoSpace Tandem Option").  Both the InfoSpace Option and the InfoSpace Tandem
Option shall vest 25% upon the date of grant and at the rate of 1.5625% per
month over the four years from the Effective Date; provided, however that
Executive has been continuously providing services to

                                       2.
<PAGE>

Employer from the Effective Date to the relevant vesting date. Both the
InfoSpace Option and InfoSpace Tandem Option shall have an exercise price per
share equal to 100% of the fair market value of InfoSpace's common stock on the
Effective Date. Except as otherwise specified herein, the terms of the InfoSpace
Option and the InfoSpace Tandem Option shall be the same as those set forth in
InfoSpace's standard form of non-qualified stock option agreement.

          (b) From Saraide Executive shall be granted a non-qualified stock
option to acquire shares of Saraide's common stock in an amount equal to 7% of
the outstanding shares of Saraide's equity securities plus that number of shares
of Saraide common stock subject to vested stock options on the Effective Date
(the "Total Outstanding Shares") (the "Saraide Option").  The Saraide Option
shall be immediately exercisable in whole or in part by Executive delivering to
Saraide a full-recourse, four-year promissory note for the purchase price with
interest payable at least annually at the minimum Federal rate applicable at the
date of the note to avoid imputation of interest (the "Early Exercise Note").
If the Saraide Option is exercised in whole or in part prior to the time such
exercised shares are vested, then such unvested exercised shares are subject to
a repurchase right at the Executive's exercise price as stated on the stock
option grant notice in favor of Saraide upon the termination of Executive's
service with the Employer, but only as to those shares remaining unvested on the
date of termination.  The Saraide Option shall have an exercise price per share
equal to 100% of the fair market value of Saraide's common stock on the
Effective Date which price shall not exceed the lowest exercise price of any
option granted by Saraide to any employee on or after the effective date of the
acquisition of Saraide by InfoSpace and prior to the Effective Date; provided,
however, that the exercise price per share of the Saraide Option shall not be
less than 85% of the fair market value of the Saraide common stock on the
Effective Date.  Except as otherwise specified herein, the terms of the Saraide
Option shall be the same as those set forth in Saraide's standard form of non-
qualified stock option agreement.

               (i)  That portion of the Saraide Option equal to 4.25% of the
     Total Outstanding Shares will be a 10-year non-qualified stock option, of
     which 1.06% (approximately 25% of this portion of the Saraide Option) will
     vest upon the date of grant and 3.19% (approximately 75% of this portion of
     the Saraide Option) will vest over the four years from the Effective Date
     at the rate of .06645% (i.e., 1/48/th/ of 3.19%) per month; provided,
     however that Executive has been continuously providing services to Employer
     from the Effective Date to the relevant vesting date.

               (ii) That portion of the Saraide Option equal to 2.75% of the
     Total Outstanding Shares will be a 10-year non-qualified stock option which
     will vest in any event on the sixth anniversary of the Effective Date and
     otherwise will vest (A) as to 1% (approximately 36% of this portion of the
     Saraide Option) when the total market capitalization of Saraide (for a
     continuous period of 10 business days and on a fully-diluted basis,
     adjusted to exclude unutilized portions of share reserves of compensatory
     stock plans, the unvested portion of outstanding stock options, and
     unvested shares of Saraide's stock) is $5.0 billion or more, (B) as to 1%
     (approximately 36% of this portion of the Saraide Option) when the total
     market capitalization of Saraide is $7.0 billion or more (calculated as
     described above), and (C) as to .75% (approximately 28% of this portion of
     the Saraide Option) when the total market capitalization of Saraide is
     $10.0

                                       3.
<PAGE>

     billion or more (calculated as described above); provided, however that
     Executive has been continuously providing services to Employer from the
     Effective Date to the relevant vesting date. Total market capitalization
     shall be determined by the closing market prices of Saraide common stock if
     publicly traded. If Saraide is not publicly traded, total market
     capitalization shall be determined by the Saraide Board in its sole
     discretion based upon relevant factors such as (x) an independent
     valuation, (y) one or more arms-length transactions, or (z) an offer to
     acquire, or a transaction involving the acquisition of, the minority
     interests in Saraide by InfoSpace.

          (c) Immediately upon the exercise, including early exercise, of any
portion of either the Saraide Option or the InfoSpace Tandem Option by
Executive, the stock option which Executive did not exercise automatically shall
be cancelled and have no further force or effect.  It is not intended that
Executive be entitled to the benefits of both the Saraide stock incentives and
the InfoSpace Tandem Option, but, ultimately, one or the other.

          (d) Notwithstanding anything to the contrary herein, Executive and
Employer acknowledge that they would prefer (i) to permit Executive to early
exercise the Saraide Option without thereby electing to take the benefits of the
Saraide Option in lieu of the InfoSpace Tandem Option; and (ii) to agree that,
upon repurchase of unvested shares that were issued to Executive upon early
exercise of the Saraide Option, Employer would repay to Executive any interest
that Executive paid on the Early Exercise Note (together, the "Intended
Provisions").  However, Executive and Employer further acknowledge that Employer
has been advised by its public accountants that neither of the Intended
Provisions described herein can be accomplished without adverse accounting
consequences to Employer.  Employer and Executive shall continue to explore
possible solutions for accomplishing the Intended Provisions without resulting
in the adverse accounting consequences.  If any such solution can be identified,
avoiding this result, for either or both of the Intended Provisions, then the
parties will execute an amendment to this Agreement incorporating the solution
or solutions.  If no such solution can be identified for either Intended
Provision, then Employer and Executive shall negotiate in good faith to reach
agreement on an arrangement to enable Executive to realize the economic benefits
of the Intended Provisions.

          (e) The initial grants of stock options provided in Sections 5(a) and
5(b) of this Agreement ("Initial Grants") may be supplemented, at the discretion
of the Boards, by additional grants based upon individual performance.

          (f) Notwithstanding the basic vesting provisions, further vesting of
the stock incentives subject to the Initial Grants will occur as follows:

               (i)  in the event of a Change of Control, 37 1/2% of the unvested
     portion of such stock incentives shall become immediately vested
     immediately prior to the effective date of the Change of Control
     transaction;

               (ii) in the event Executive's employment is terminated upon or
     within 13 months following a Change of Control either (A) by Employer
     without Cause or (B) by Executive for Good Reason, an additional 37 1/2% of
     the unvested portion of such stock incentives shall become immediately
     vested;

                                       4.
<PAGE>

               (iii) if Executive's service with Employer is terminated by
     reason of his death or Disability (as defined in Section 8(b)), then
     vesting of such stock incentives shall be accelerated by one year;

               (iv)  if Executive's service with Employer is terminated by
     Employer without Cause, then additional vesting of such stock incentives
     shall occur as follows:

                      (A) if such termination occurs during the first year after
          the Effective Date, then Executive shall be credited with an
          additional 12 months of vesting;

                      (B) if such termination occurs during the second year from
          the Effective Date, then Executive shall be credited with an
          additional six months of vesting;

                      (C) if such termination occurs after the second year from
          the Effective Date, then Executive shall be credited with an
          additional three months of vesting.

               (v)   if Executive's service with Employer is terminated by
Employee for Good Reason, then Executive shall be credited with an additional
six months of vesting.

          (g) The stock incentives subject to the Initial Grants shall be
exercisable after Executive's termination of service with Employer as follows:

               (i)   if termination is by reason of death, Disability,
     termination by Employer without Cause, or termination by Executive for Good
     Reason, the stock incentives shall be exercisable (A) 18 months after the
     date of termination if at such date the common stock of Saraide is publicly
     traded or (B) three years from the date of termination if at such date the
     common stock of Saraide is not publicly traded;

               (ii)  if termination of service is by Employer for Cause, the
     stock incentives shall be exercisable within 14 days after the date of
     termination;

               (iii) if termination of service is by Executive, other than for
     Good Reason, the stock incentives shall be exercisable until 90 days after
     the date of termination.

               (iv)  if termination of service is by Executive voluntarily
     within 12 months of the Effective Date and is not by reason of death,
     Disability, termination by Employer without Cause, or termination by
     Executive for Good Reason, the 25% of such stock incentives which vested
     immediately on the Effective Date shall be reduced by one-twelfth (2.083%)
     for each full month by which the duration of Executive's employment from
     the Effective Date is fewer than 12 months, notwithstanding any other
     provision of the stock incentives.

          (h) In the event that the acceleration of the vesting and
exercisability of the stock incentives and/or the lapse of reacquisition or
repurchase rights with respect to the stock

                                       5.

incentives provided for in subsection 5(f)(i) and (ii) and benefits otherwise
payable to Executive, but determined without regard to any additional payments
required under this subsection 5(h) (a "Payment"), would be subject to the
excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as
amended (the "Code"), or any comparable federal, state, or local excise tax
(such excise tax, together with any interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then Executive shall be entitled
to receive an additional payment (a "Gross-Up Payment") in such an amount that
after the payment of all taxes (including without limitation, any interest and
penalties on such taxes and the excise tax) on the Payment and on the Gross-Up
Payment, Executive shall retain an amount equal to the Payment minus all
applicable income and individual employment taxes on the Payment. The intent of
the parties is that the Company shall be solely responsible for, and shall pay,
any Excise Tax on the Payment and Gross-Up Payment and any income, employment
and other taxes (including, without limitation, penalties and interest) imposed
on any Gross-Up Payment, as well as any loss of tax deduction caused by the
Gross-Up Payment or applicable provisions of the Code. All determinations
required to be made under this subsection 5(h), including without limitation,
whether and when a Gross-Up Payment is required and the amount of such Gross-Up
Payment and the assumptions to be utilized in arriving at such determinations,
shall be made by a nationally recognized accounting firm that is the Company's
outside auditor at the time of such determinations, which firm must be
reasonably acceptable to Executive (the "Accounting Firm"). All fees and
expenses of the Accounting Firm shall be borne solely by the Company.

     6.  Benefits.  Executive shall be entitled to four weeks vacation time per
         --------
calendar year, which vacation time shall be scheduled at the mutual convenience
of Executive and Employer.  Executive shall be entitled to all rights and
benefits for which he is eligible under the terms and conditions of the standard
InfoSpace benefits and compensation plans which may be in effect from time to
time and provided by InfoSpace to its executive level employees generally.
Notwithstanding the foregoing, Employer may, in its discretion, at any time and
from time to time, change or revoke any of its employee benefits plans, programs
or policies, and Executive shall not be deemed, by virtue of this Agreement, to
have any vested interest in any such plans, programs or policies.

     7.  Expenses.  The Employer shall reimburse Executive for all reasonable
         --------
travel, entertainment or other expenses incurred by him in furtherance of or in
connection with the performance of his duties hereunder, in accordance with the
Employer's expense reimbursement policy as in effect from time to time.
Executive shall also be entitled to reimbursement by Employer for the reasonable
cost of a car and driver between his residence and Saraide's offices.

     8.  Termination.  Executive's employment hereunder may be terminated
         -----------
without any breach of this Agreement only under the following circumstances:

          (a) Death.  Executive's employment hereunder shall terminate upon his
death.

          (b) Disability.  Executive's employment with the Employer will be
terminated in the event of Executive's illness, disability or other incapacity
that renders Executive physically and/or mentally unable regularly to perform
the essential duties of his positions hereunder for a period in excess of 120
consecutive days, or in excess of 180 days in any consecutive 12 month

                                       6.
<PAGE>

period ("Disability"). The determination regarding whether Executive has reached
Disability status shall be made by the Boards in good faith.

          (c) Cause.  Employer may terminate Executive's employment hereunder
for Cause.  For purposes of this Agreement, Employer shall have "Cause" to
terminate Executive's employment hereunder upon Executive's:

               (i)   conviction of a felony or any crime involving moral
     turpitude or dishonesty; or

               (ii)  gross neglect or refusal to substantially perform his
     duties hereunder (other than that resulting from Executive's Disability)
     after demand for substantial performance is delivered by either Board in
     writing that specifically identifies the manner in which the Board believes
     Executive has not substantially performed his duties and Executive does not
     remedy such neglect or refusal within 30 days following receipt of such
     written notice;

               (iii) participation in a fraud or act of dishonesty against
     Employer; or

               (iv)  intentional and material damage to the Employer's property;

               (v)   material breach of this Agreement, InfoSpace's written
     policies, or either [Proprietary Information and Inventions Agreement],
     that is not remedied by Executive within 14 days of written notice of such
     breach from either Board;

               (vi)  serious misconduct or conduct by Executive which
     demonstrates Executive's gross unfitness to serve the Employer, as
     determined by either Board.

     Cause shall not exist unless and until Employer has delivered to Executive
a copy of a resolution duly adopted by a majority of the Board or Boards at a
meeting or meetings called and held for such purpose (after reasonable notice to
the Executive and an opportunity for Executive, together with his counsel, to be
heard before the Board or Boards), finding that in the good faith opinion of
either Board, the conduct set forth in this Section 8(c) occurred, and
specifying the particulars thereof.

          (d) Good Reason.  Executive may establish "Good Reason" for
termination of his employment by notifying the Employer in writing, within 10
days after the occurrence of one of the following events, that Executive intends
to terminate his employment for Good Reason in 30 days if the circumstance has
not been cured before then, and then if the circumstance has not been cured
within 30 days, by submitting his resignation effective within 10 days after the
30-day period.  The events or circumstances upon which termination for Good
Reason can be based are as follows:

               (i)   the reassignment of Executive by Employer, without
     Executive's express written consent, to a position with Employer other than
     those set forth in Section 2 hereof;

                                       7.
<PAGE>

               (ii)  a significant adverse change in Executive's title,
     authority, powers, functions, duties or responsibilities, provided that
     change resulting from the acquisition of the Employer by another company,
     where Executive's titles and authority remain unchanged, and the Employer
     remains essentially intact, will not constitute "Good Reason";

               (iii) a reduction in Executive's Base Salary without Executive's
     consent;

               (iv)  the relocation of Executive's work location outside of the
     San Francisco Bay Area without the Executive's consent;

               (v)   Employer's failure to perform its obligations under this
     Agreement in any material respect; or

               (vi)  the failure of a successor to the Employer in a Change of
     Control to expressly assume and agree to perform this Agreement in the same
     manner and to the same extent that Employer would be required to perform it
     if no such Change of Control had taken place.  Failure of Employer to
     obtain such assumption and agreement prior to the effectiveness of any such
     succession, without regard to the 30-day notice provision above, shall be a
     material breach of this Agreement.

          (e) Termination Without Cause.  Employer may terminate Executive's
employment without Cause at any time upon 30 days' written notice.

          (f) Termination Without Good Reason.  Executive may terminate
employment without Good Reason at any time upon 30 days' written notice.

     9.  Compensation Upon Termination.
         ------------------------------

          (a) Death or Disability. If Executive's employment is terminated by
his death or his Disability, then Employer shall pay to Executive (or his legal
representatives or estate or as may be directed by the legal representatives of
his estate, as the case may be) any accrued and unpaid Base Salary and vacation
pay immediately, and expense reimbursements within thirty 30 days of
termination.

          (b) Termination by Employer (Without Cause); or By Executive for Good
Reason After Change of Control.  If Executive's employment is terminated by the
Employer without Cause, or upon or within six months following a Change of
Control, by Executive for Good Reason, then upon Executive's providing the
Employer a general release and waiver of all claims in a form acceptable to the
Employer, Employer shall continue to pay Executive's Base Salary for six months
following the termination, in accordance with InfoSpace's standard payroll
procedures.

          (c) Termination By the Employer for Cause; or By Executive Other Than
for Good Reason After Change of Control.  If Executive's employment is
terminated by Employer for Cause, or by Executive other than for Good Reason
upon or within six months following a Change of Control, then:

                                       8.
<PAGE>

               (i)   Employer shall immediately pay Executive his accrued but
     unpaid Base Salary and vacation pay, and within 30 days of termination, his
     unpaid expense reimbursements;

               (ii)  notwithstanding anything contained herein to the contrary,
     none of the stock incentives granted pursuant to Section 5 shall vest after
     the date of termination and all unvested options shall immediately
     terminate;

               (iii) except as specifically provided herein, Executive shall
     receive no further compensation or benefits, and Employer shall have no
     additional obligation to Executive under this Agreement.

     10. Other Agreements.
         ----------------

          (a) Proprietary Information and Inventions Agreements.  Executive
shall execute and comply with both the InfoSpace and Saraide forms of Employee
Proprietary Information and Inventions Agreement attached as Exhibits A and B
hereto and incorporated herein by reference.  Executive's duties under the
Proprietary Information and Inventions Agreements shall survive termination of
Executive's employment with the Employer.  Executive acknowledges that a remedy
at law for any breach or threatened breach by Executive of the provisions of the
Proprietary Information and Inventions Agreements would be inadequate and
Executive therefore agrees that the Employer shall be entitled to injunctive
relief in case of any such breach or threatened breach.  If Executive breaches
any of the provisions of either of the Proprietary Information and Inventions
Agreements, then Employer, in addition to all other rights and remedies
thereunder, may cease making payments to Executive under subsection 9(b) of this
Agreement and require Executive to repay to Employer any payments previously
made under such subsections.

          (b) Indemnification.  InfoSpace and Saraide shall, to the fullest
extent permitted by applicable Delaware law, and in accordance with their
respective Bylaws and Charters, indemnify Executive and hold him harmless from
any cost, expense or liability arising out of or relating to any acts or
decisions made by him within the course and scope of his duties hereunder.
Employee shall be added as an additional named insured under all appropriate
insurance policies now in force or hereinafter obtained by Employer.  Any
termination of Executive's employment or of this Agreement shall have no effect
on the continuing operation of this Section.

          (c) No Conflicting Agreements.  Executive represents and warrants that
his employment by the Employer will not conflict with and will not be
constrained by any prior agreement or relationship with any third party.
Executive represents and warrants that he will not disclose to the Employer or
use on behalf of the Employer any confidential information governed by any
agreement with any third party except in accordance with an agreement between
the Employer and any such third party.  During Executive's employment by the
Employer, Executive may use, in the performance of his duties, all information
generally known and used by persons with training and experience comparable to
his own and all information which is common knowledge in the industry or
otherwise legally in the public domain.

                                       9.
<PAGE>

          (d) Outside Activities.

               (i)  Investments and Interests.  Except as permitted by Section
     10(d)(ii), Executive agrees, during his employment by the Employer, not to
     acquire, assume or participate in, directly or indirectly, any position,
     investment or interest known by him to be adverse or antagonistic to the
     Employer, its business or prospects, financial or otherwise.

               (ii) Non-Competition.  During his employment by the Employer
     except on behalf of the Employer, Executive will not directly or
     indirectly, whether as an officer, director, founder, stockholder, partner,
     proprietor, associate, representative, consultant, employee, or in any
     capacity whatsoever engage in, become financially interested in, be
     employed by or have any business connection with any other person,
     corporation, firm, partnership or other entity whatsoever known by him to
     compete directly with the Employer, anywhere in the world, in any line of
     business engaged in (or planned to be engaged in) by the Employer;
     provided, however, that anything above to the contrary notwithstanding,
     Executive may own, as a passive investor, securities of any competitor
     corporation, so long as Executive's direct holdings in any one such
     corporation shall not in the aggregate constitute more than 1% of the
     voting stock of such corporation.

          (e) Upon its acquisition of Saraide InfoSpace shall transfer to
Saraide all of the business, assets and technology in wireless
telecommunications to Saraide.

     11. Change of Control.  For purposes of this Agreement, a "Change of
         -----------------
Control" shall be deemed to occur if:

          (a) any "person" (as such term is utilized in Section 13(d) and
Section 14(d)(2) of the Exchange Act), including without limitation any "group"
(as such term is utilized in Section 13(d)(3) of the Exchange Act), shall become
the "beneficial owner" (as such term is defined in Rule 13d-3 under the Exchange
Act) of securities of InfoSpace or Saraide (other than InfoSpace, a controlled
affiliate of InfoSpace, or an employee benefit plan sponsored by InfoSpace or
such controlled affiliate) representing more than 50% of the votes that may be
cast for the election of directors of InfoSpace or Saraide as the case may be;
or

          (b) a merger or consolidation involving InfoSpace or Saraide
("Involved Entity") in which the Involved Entity is not the surviving entity,
except for (i) a transaction the principal purpose of which is to change the
state of the Involved Entity's incorporation, or (ii) a transaction in which the
Involved Entity's stockholders immediately prior to such merger or consolidation
hold (by virtue of securities received in exchange for their shares in the
Involved Entity) securities of the surviving entity representing more than 50%
of the total voting power of such entity immediately after such transaction;

          (c) the sale, transfer or other disposition of all or substantially
all of the assets of the Involved Entity unless the Involved Entity's
stockholders immediately prior to such sale, transfer or other disposition hold
(by virtue of securities received in exchange for their shares in the Involved
Entity) securities of the purchaser or other transferee representing more than
50% of the total voting power of such entity immediately after such transaction;
or

                                      10.
<PAGE>

          (d) any reverse merger in which the Involved Entity is the surviving
entity but in which the Involved Entity's stockholders immediately prior to such
merger do not hold (by virtue of their shares in the Involved Entity held
immediately prior to such transaction) securities of the Involved Entity
representing more than 50% of the total voting power of the Involved Entity
immediately after such transaction.

         -------

               PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT

As an employee of SARAIDE, INC., any of its subsidiary or affiliates (together,
the "Company") and as a condition of my employment by the Company and in
consideration of the compensation now and hereafter paid to me, I agree to the
following.

1.   MAINTAINING CONFIDENTIAL INFORMATION

     1.1  Company Information - I agree at all times during the term of my
employment and thereafter to hold in strictest confidence, and not to use,
except as required in connection with my work for the Company, or to disclose to
any person, firm or corporation, without the written authorization of an officer
of the Company, any trade secrets, confidential knowledge, data or other
proprietary information of the Company.  By way of illustration and not
limitation, such shall include information relating to products, processes,
know-how, designs, formulas, source code, object code, programs, methods,
samples, developmental or experimental work, improvements, discoveries, plans
for research, new products, marketing and selling, business plans, budgets and
unpublished financial statements, licenses, prices and costs, suppliers and
customers, and information regarding the skills and compensation of other
employees of the Company.  I further agree to obtain the Company's written
approval before publishing or submitting for publication any material (written,
verbal or otherwise) that relates to my work at the Company and/or incorporates
any confidential or proprietary information of the Company.

     1.2  Former Employer Information - I agree that I will not, during my
employment with the Company, improperly use or disclose any proprietary
information or trade secrets of my former or concurrent employers or companies,
if any, and that I will not bring onto the premises of the Company any
unpublished documents or any property belonging to my former or concurrent
employers or companies unless consented to in writing by said employers or
companies.  I will use in the performance of my duties only information which is
generally known and used by persons with training and experience comparable to
my own, which is common knowledge in the industry or otherwise legally in the
public domain, or which is otherwise provided or developed by the Company.

     1.3  Third Party Information - I recognize that the Company has received
and in the future will receive confidential or proprietary information from
third parties subject to a duty on the Company's part to maintain the
confidentiality of such information and, in some cases, to use it only for
certain limited purposes.  I agree that I owe the Company and such third
parties, both during the term of my employment and thereafter, a duty to hold
and will so hold all such confidential or proprietary information in the
strictest confidence and not to disclose it to any person, firm or corporation
(except in a manner that is consistent with the Company's agreement with the
third party) or use it for the benefit of anyone other than the Company or such
third party (consistent with the Company's agreement with the third party),
unless expressly authorized to act otherwise by an officer of the Company.

2.   ASSIGNMENT OF INVENTIONS AND ORIGINAL WORKS

     2.1  Inventions and Original Works Retained by Me - I have attached hereto
as Exhibit A a complete list of all inventions, original works of authorship,
developments, improvements, and trade secrets that I have, alone or jointly with
others, conceived, developed or reduced to practice or caused to be conceived,
developed or reduced to practice prior to the commencement of my employment with
the Company and which I consider to be my property or the property of third
parties and that I wish to have excluded from the scope of this Agreement
(collectively referred to as "Prior Inventions").  If disclosure of an item on
Exhibit A would cause me to violate any prior confidentiality agreement, I
understand that I am not to list such in Exhibit A but I am to inform the
Company that items have not been listed for that reason.  A space is provided on
Exhibit A for such purpose.  If no list is attached, I represent that there are
no such items.  If, in the course of my employment with the Company, I
incorporate a Prior Invention into a Company product, process or machine, the
Company is hereby granted and shall have a nonexclusive, royalty-free,
irrevocable, perpetual, worldwide license (with rights to sublicense through
multiple tiers of sublicensees) to make, have made, modify, use and sell such
Prior Invention.  Notwithstanding the

                                      (1)
<PAGE>

foregoing, I agree that I will not incorporate, or permit to be incorporated,
Prior Inventions in any work done for the Company without the Company's prior
written consent.

     2.2  Inventions and Original Works Assigned to the Company - I agree that I
will make prompt written disclosure to the Company, will hold in trust for the
sole right and benefit of the Company, and hereby assign to the Company all my
rights, title and interest in and to any ideas, inventions, original works of
authorship, developments, improvements or trade secrets which I may solely or
jointly conceive or reduce to practice, or cause to be conceived or reduced to
practice, during the period of my employment with the Company.

          2.2.1  I recognize that this Agreement does not require assignment of
     any invention which  I have developed entirely on my own time without using
     the Company's equipment, supplies, facilities, or trade secret information
     except for those inventions that either:

                 (a) relate at the time of conception or reduction to practice
          of the invention to the Company's business, or actual or demonstrably
          anticipated research or development of the Company; or,

                 (b) result from any work performed by myself for the Company.

          2.2.2  I acknowledge that all original works of authorship which are
     made by me (solely or jointly with others) within the scope of my
     employment and which are protectable by copyright are "works made for
     hire," as that term is defined in the United States Copyright Act (17
     U.S.C., Section 101) or the "in the course of employment" within the
     meaning of the Copyright Act of Canada (Section 13 (3))and belong to the
     Company.  I hereby further waive any moral rights I may otherwise claim on
     such works of authorship and copyright.

          2.2.3  This Agreement may not apply to an invention, improvement,
     discovery or development which qualifies fully as nonassignable under
     Section 2870 of the California Labor Code (hereinafter "Section 2870").  I
     have reviewed the notification on Exhibit B (Limited Exclusion
     Notification) and agree that my signature acknowledges receipt of the
     notification.

     2.3  Obtaining Letters Patent, Copyright Registrations and Other
Protections - I will assist the Company in every proper way to obtain and
enforce Canadian, United States and foreign proprietary rights relating to any
and all inventions, original works of authorship, developments, improvements or
trade secrets of the Company in any and all countries.  To that end I will
execute, verify and deliver such documents and perform such other acts
(including appearing as a witness) as the Company may reasonably request for use
in applying for, obtaining, evidencing, sustaining and enforcing or to perfect
such proprietary rights and the assignment thereof. In addition, I will execute,
verify and deliver assignments of such proprietary rights to the Company or its
designee.  My obligation to assist the Company with respect to proprietary
rights in any and all countries shall continue beyond the termination of my
employment, but the Company shall compensate me at a reasonable rate after my
termination for the time actually spent by me at the Company's request on such
assistance.

In the event the Company is unable for any reason, after reasonable effort, to
secure my signature on any document needed in connection with the actions
specified in the preceding paragraph, I hereby irrevocably designate and appoint
the Company and its officers and agents as my agent and attorney-in-fact, to act
for and in my behalf to execute, verify and file any such documents and to do
all other lawfully permitted acts to further the purposes of the preceding
paragraph with the same legal force and effect as if executed by me.  I hereby
waive and quitclaim to the Company any and all claims of any nature whatsoever
which I now or may hereafter have for infringement of any proprietary rights
assigned to the Company.

     2.4  Obligation to Keep the Company Informed -  In addition to my
obligations under paragraph 2 above, during the period of my employment and for
one (1) year after termination of my employment for any reason, I will promptly
disclose to the Company fully and in writing all patent applications filed by me
or on my behalf.  At the time of each such disclosure, I will advise the Company
in writing of any inventions that I believe are

                                      (2)
<PAGE>

not inventions and original works assigned to the Company and I will at that
time provide to the Company in writing all evidence necessary to substantiate
that belief. I understand that the Company will keep in confidence and will not
disclose to third parties without my consent any proprietary information
disclosed in writing to the Company pursuant to this Agreement relating to
inventions that are not inventions and original works assigned to the Company. I
will preserve the confidentiality of any invention that is an invention and
original work assigned to the Company. I agree to keep and maintain adequate and
current records (in the form of notes, sketches, drawings and in any other form
that may be required by the Company) of all proprietary information developed by
me and all inventions made by me during the period of my employment at the
Company, which records shall be available to and remain the sole property of the
Company at all times.

3.   NO CONFLICTING EMPLOYMENT, NO INDUCEMENT OF OTHER EMPLOYEES OR SOLICITATION
     OF CUSTOMERS

     3.1  I agree that during the period of my employment by the Company I will
not, without the Company's express written consent, engage in any employment or
business activity which is competitive with or would otherwise conflict with the
business in which the Company is now involved or becomes involved nor will I
engage in any other activities which conflict with my obligations to the
Company.  For the period of my employment by the Company and for one (1) year
after the date of termination of my employment by the Company I will not induce
any employee of the Company to leave the employ of the Company.

If any restriction set forth in this agreement is found by any court of
competent jurisdiction to be unenforceable because it extends for too long a
period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

4.   NO CONFLICTING OBLIGATIONS

     4.1  I represent that my performance of all the terms of this Agreement and
as an employee of the Company does not and will not breach any agreement to keep
in confidence information acquired by me in confidence or in trust prior to my
employment by the Company.  I have not entered into, and I agree I will not
enter into, any agreement either written or oral in conflict herewith.

5.   RETURN OF COMPANY DOCUMENTS

     5.1  When I leave the employ of the Company, I will deliver to the Company
(and will not keep in my possession, recreate or deliver to anyone else) any and
all devices, records data, notes, reports, proposals, lists, correspondence,
specifications, drawings, blueprints, sketches, materials, equipment, electronic
mail, other documents or property, together with all copies thereof (in whatever
medium recorded) belonging to the Company, its successors or assigns.  I agree
that any property situated on the Company's premises and owned by the Company,
including disks and other storage media, filing cabinets or other work areas, is
subject to inspection by Company personnel at any time with or without notice.
Prior to leaving, I will cooperate with the Company in completing and signing
the Company's termination statement.

6.   NOTIFICATION OF NEW EMPLOYER

     6.1  In the event that I leave the employ of the Company, I hereby consent
to the notification of my new employer of my rights and obligations under this
Agreement.

7.   LEGAL AND EQUITABLE REMEDIES

     7.1  Because my services are personal and unique and because I may have
access to and become acquainted with the proprietary information of the Company,
the Company shall have the right to enforce this

                                      (3)
<PAGE>

Agreement and any of its provisions by injunction, specific performance or other
equitable relief, without bond and without prejudice to any other rights and
remedies that the Company may have for a breach of this Agreement.

8.   GENERAL PROVISIONS

     8.1  Not an Employment Contract - I agree and understand that nothing in
this Agreement shall confer any right with respect to continuation of employment
by the Company, nor shall it interfere in any way with my right or the Company's
right to terminate my employment at any time, with or without cause.

     8.2  Governing Law - This Agreement will be governed by and construed
according to the laws of the State of California in the United States of America
excluding conflicts of laws principles.  I hereby expressly consent to the venue
and personal jurisdiction of the state and federal courts located in San Mateo
County, California for any lawsuit filed there against me by the Company arising
from or relating to this Agreement.

     8.3  Severability - In case any one or more of the provisions contained in
this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect the other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein.  If moreover, any one or more of the provisions
contained in this Agreement shall for any reason be held to be excessively broad
as to duration, geographical scope, activity or subject, it shall be construed
by limiting and reducing it, so as to be enforceable to the extent compatible
with the applicable law then appear.

     8.4  Successors and Assigns - This Agreement will be binding upon my heirs,
executors, administrators and other legal representatives and will be for the
benefit of the Company, its successors and its assigns.

     8.5  Survival - The provisions of this Agreement shall survive the
termination of my employment and the assignment of this Agreement by the Company
to any successor in interest or other assignee.

     8.6  Waiver - No waiver by the Company of any breach of this Agreement
shall be a waiver of any preceding or succeeding breach.  No waiver by the
Company of any right under this Agreement shall be construed as a waiver of any
other right.  The Company shall not be required to give notice to enforce strict
adherence to all terms of this Agreement.

     8.7  Notice - Any notice required or permitted hereunder shall be given to
the appropriate party at the address specified below or at such other address as
the party shall specify in writing.  Such notice shall be deemed given upon
personal delivery, or sent by certified or registered mail, postage prepaid,
three (3) days after the date of mailing.

     8.8  Entire Agreement - This Agreement and its exhibits, attached hereto
and hereby incorporated herein, set forth the final, entire and exclusive
agreement and understanding between the Company and me relating to the subject
matter hereof and supersedes all prior and contemporaneous understandings and
agreements relating to its subject matter.  No modification of or amendment to
this Agreement, nor any waiver of any rights under this Agreement, will be
effective unless in writing signed by both the Company and me.  Any subsequent
change or changes in my duties, salary or compensation will not affect the
validity or scope of this Agreement.

This Agreement shall be effective as of the first day of my employment with the
Company, namely:________________, 2000.

I UNDERSTAND THAT THIS AGREEMENT AFFECTS MY RIGHTS TO INVENTIONS I MAKE DURING
MY EMPLOYMENT, AND RESTRICTS MY RIGHT TO DISCLOSE OR USE THE COMPANY'S
PROPRIETARY INFORMATION DURING AND SUBSEQUENT TO MY EMPLOYMENT.

                        LIMITED EXCLUSION NOTIFICATION

     THIS IS TO NOTIFY you in accordance with Section 2872 of the California
Labor Code that the foregoing Agreement between you and the Company does not
require you to assign or offer to assign to the Company any invention that you
developed entirely on your own time without using the Company's equipment,
supplies, facilities or trade secret information except for those inventions
that either:

     1.  Relate at the time of conception or reduction to practice of the
invention to the Company's business, or actual or demonstrably anticipated
research or development of the Company;

     2.  Result from any work performed by you for the Company.

     To the extent a provision in the foregoing Agreement purports to require
you to assign an invention otherwise excluded from the preceding paragraph, the
provision is against the public policy of this state and is unenforceable.

     This limited exclusion does not apply to any patent or invention covered by
a contract between the Company and the United States or any of its agencies
requiring full title to such patent or invention to be in the United States.

  I ACKNOWLEDGE RECEIPT of a copy of this notification.
