                                       4



     3.4 Royalty Obligation and Conditional Transfer of LICENSED TECHNOLOGY. The
royalties  agreed to  hereunder  shall be paid until the  earlier of the date on
which  LICENSEE  has paid  LICENSOR an  aggregate  of Four  Million Five Hundred
Thousand U.S. Dollars  ($4,500,000) or the fifth  anniversary of Effective Date.
("TOTAL ROYALTY").  If LICENSEE pays LICENSOR the TOTAL ROYALTY,  LICENSOR shall
assign and transfer to LICENSEE all of LICENSOR's rights, title and interests in

               (i) shall pay all  royalties  set forth in this Section 3 accrued
          and payable for such period, and

               (ii) furnish  LICENSOR with a royalty report along with a written
          statement  certified  by an officer of LICENSEE  (a) stating  that the

          for the calculation of such royalties.

All payments due to LICENSOR shall be made solely in U.S. Dollars in immediately
available  funds, via wire transfer to such account as is designated by LICENSOR
in writing to LICENSEE.  Late payments  shall accrue  interest from the date due
until the date paid at a rate of one percent (1%) per month, or the maximum rate
allowed under applicable law,  whichever is less.  LICENSEE shall make no offset
for any  amounts  due to  LICENSOR  regardless  of the  justification  for  such
intended offset.

     3.6 Right of  Audit.  During  the TERM and for  three  (3) years  after the
expiration  and  termination  of this  AGREEMENT  for  any  reason  (the  "AUDIT
PERIOD"), LICENSEE shall keep complete, true and accurate records containing all
invoices  and other data  related to the  computation  and  verification  of the
royalties  to be paid  under  Section  3 and  any  other  amounts  to be paid to
LICENSOR, and (b) the basis of information provided in the royalty report or any
statements  provided by LICENSEE to LICENSOR pursuant to this AGREEMENT.  During
the AUDIT PERIOD LICENSEE shall permit  LICENSOR or its designees or agents,  at
LICENSOR's  expense and upon ten (10) days prior written notice,  to inspect and
make copies of such records for the sole  purpose of  verifying  the accuracy of
the royalties and other payments made by LICENSEE under this AGREEMENT. LICENSEE
shall itself, and shall cause its accountants to, diligently  cooperate with the
audit. If any audit reveals any underpayment by LICENSEE,  LICENSEE shall within
ten (10) days after such audit remit to LICENSOR all amounts due,  with interest
thereon at the rate of one  percent  (1%) per month  compounded  (or the highest
rate permitted by applicable law, whichever is lower),  calculated from the date
such amounts were due. If any underpayment is more than five percent (5%) of the
total payments due for the period  audited,  LICENSEE shall remit to LICENSOR in
full all costs for such audits and the subsequent audit, including any fees of a
certified public accountant.

     3.7 Taxes.  In  addition  to any other  amounts  due under this  AGREEMENT,
LICENSEE  agrees to pay,  indemnify  and hold  LICENSOR  harmless from any TAXES

                                       5



imposed by any  governmental  authority  with respect to  LICENSEE's  use of the
LICENSED  TECHNOLOGY.  "TAXES"  herein  means any tax,  fee or cost not based on
LICENSOR's net income, including any sales, use, excise, import or export, value
added,  withholding  or similar  tax,  or any duty or fee and any  penalties  or
interest  associated  with any of the  foregoing.  LICENSEE's  obligation to pay
TAXES  shall  survive  any  expiration  or   termination   of  this   AGREEMENT.
Notwithstanding  the foregoing,  if LICENSEE is required by U.S. or other law to
withhold  any amount from sums  payable to LICENSOR  hereunder,  LICENSEE  shall
deduct  and pay any  withholding  taxes to the  appropriate  U.S.  or other  tax
authorities,  respectively,  and  shall  provide  LICENSOR  with  a tax  receipt
evidencing such payment.

to protect the LICENSED  PATENTS in any other country.  During the TERM LICENSEE
shall prosecute  and/or  maintain,  as appropriate,  the LICENSED  PATENTS in at
least the  countries in which  LICENSOR  has already  begun  prosecution  and/or
maintenance  ("PROSECUTION  COUNTRIES"),  a list of which  shall be  provided by
LICENSOR upon request.  LICENSEE  shall keep LICENSOR  fully  informed as to the
status  of such  patent  matters,  including  without  limitation  by  providing
LICENSOR with the  opportunity to review and comment on any documents which will
be filed in any patent office and by providing  LICENSOR copies of any documents
received  by  LICENSEE  from  such  patent  offices  including  notices  of  all
interferences,   reexaminations,   oppositions   or  requests  for  patent  term
extensions.  In the event that  LICENSEE  declines  or fails to  prepare,  file,
prosecute or maintain any LICENSED PATENTS in any PROSECUTION COUNTRY,  LICENSEE
shall promptly,  and in no event later than ninety (90) days prior to any filing
deadline,  provide  written  notice to LICENSOR and LICENSOR shall then have the
right to assume such  responsibilities  at its own expense  using counsel of its
choice. In addition,  LICENSEE shall promptly notify LICENSOR of any decision to
abandon a patent or application  covered by the LICENSED PATENTS in any country,
in which case,  LICENSOR shall have the option,  at its expense and with counsel
of its choice, of continuing to prosecute any such pending patent application or
of keeping the issued patent in force. If LICENSEE  abandons,  declines or fails

                                       6



to prepare,  file,  prosecute or maintain  any LICENSED  PATENTS as set forth in

alleged  or  threatened  INTELLECTUAL  PROPERTY  infringement  of  the  LICENSED
TECHNOLOGY  which may adversely impact the rights of the parties  hereunder,  of
which it becomes aware.

     5.2  Enforcement.  In the event  that  either  party  becomes  aware of any
alleged  or  threatened  INTELLECTUAL  PROPERTY  infringement  of  the  LICENSED
TECHNOLOGY, as between the parties, LICENSEE shall have the first right, but not
the obligation, to take appropriate action against any person or entity directly
or  contributorily  infringing  such  LICENSED  TECHNOLOGY,  and to  retain  any
recovery from such action. In furtherance of such right,  LICENSOR hereby agrees
that  LICENSEE may join  LICENSOR as a party in any such action  (with  LICENSOR

desires and at its own  expense,  by counsel of its own  selection)  and to give
LICENSEE  reasonable  assistance and any needed  authority to control,  file and
prosecute such action,  without  expense to LICENSOR.  If LICENSEE does not file
suit against a substantial infringer within six (6) months of knowledge thereof,
then LICENSOR may, at its sole  discretion,  enforce any  INTELLECTUAL  PROPERTY
RIGHTS in any LICENSED TECHNOLOGY licensed hereunder,  provided LICENSOR does so
both on behalf of itself and LICENSEE,  with LICENSOR  retaining all  recoveries
from such enforcement. In furtherance of such right, LICENSEE hereby agrees that
LICENSOR may join LICENSEE as a party in any such action (with  LICENSEE  having
the right to participate in such action and to be represented,  if it so desires
and at its own expense,  by counsel of its own  selection)  and to give LICENSOR
reasonable  assistance and any needed  authority to control,  file and prosecute

agree to  cooperate  fully with each other at the expense of the party  bringing
the suit.  Cooperation  shall include  permitting access during regular business
hours upon  reasonable  notice,  to all  relevant  personnel,  records,  papers,
information, samples, specimens, and the like in its possession.

     5.4  Licenses to Abate Third Party  Infringement.  LICENSEE  shall have the
sole right in accordance with the terms and conditions  herein to sublicense the
rights granted to LICENSEE under Section 2.1 to any alleged infringer.

provided  herein,  disclose,  disseminate  or  otherwise  allow  access  to  the
CONFIDENTIAL INFORMATION of DISCLOSER to anyone other than RECIPIENT's employees
that  have a need  to know  such  CONFIDENTIAL  INFORMATION  to  implement  this
AGREEMENT  and  who  are  bound  by  written  confidentiality  obligations  with
provisions no less stringent than those contained in this Section VII. RECIPIENT
shall prevent unauthorized disclosure or use of the CONFIDENTIAL  INFORMATION of
DISCLOSER.  DISCLOSER  and  RECIPIENT  shall execute any documents and otherwise
shall take all necessary steps to ensure that DISCLOSER and RECIPIENT shall each
be able to enforce DISCLOSER's rights hereunder against RECIPIENT, its employees
and all other third parties to whom RECIPIENT discloses DISCLOSER's CONFIDENTIAL
INFORMATION,   under  the  laws  of  each   jurisdiction  in  which  DISCLOSER's
CONFIDENTIAL   INFORMATION  is  disclosed  by  RECIPIENT.   RECIPIENT  shall  be
responsible  for  any  breach  of this  Section  VII by  RECIPIENT's  employees,
contractors or agents.

INFORMATION.

     7.3  Notification.  If RECIPIENT learns or believes that any person who has
had access to the CONFIDENTIAL  INFORMATION of DISCLOSER has violated or intends
to violate this AGREEMENT,  RECIPIENT  shall  immediately  notify  DISCLOSER and
shall cooperate with DISCLOSER in seeking  injunctive or other equitable  relief
against any such person.

     7.4  Exceptions.  RECIPIENT may disclose the  CONFIDENTIAL  INFORMATION  of
DISCLOSER,  if such  disclosure  is required  by law,  provided  that  RECIPIENT
promptly  notifies  DISCLOSER to allow  intervention by DISCLOSER  (prior to the
disclosure),  cooperates  with  DISCLOSER to contest or minimize the  disclosure
(including application for a protective order) at RECIPIENT's expense and limits
such  disclosure to the party entitled to receive the  CONFIDENTIAL  INFORMATION
and to the scope of the legal requirement.  Notwithstanding  the foregoing,  any
CONFIDENTIAL  INFORMATION disclosed pursuant to this Section 7.4 shall otherwise
continue to be treated as CONFIDENTIAL INFORMATION hereunder.

     7.5 Confidentiality of AGREEMENT.  Neither party will publicly disclose any
term of this AGREEMENT or announce the existence of this  AGREEMENT  without the
prior written consent of the other party,  except that each party may reveal the

terms  of this  AGREEMENT  (a) to its  accountants,  banks,  financing  sources,
lawyers and other professional advisors, provided that such parties undertake in
writing to keep such information confidential,  or (b) as required by applicable
laws  and  regulations  including  those  of the U.S.  Securities  and  Exchange
Commission on the  notification.  Each party may also disclose the tax treatment

this AGREEMENT if the other party breaches this AGREEMENT and fails to cure such
breach within thirty (30) days following the date the breaching party receives a
written  breach  notice  from the  non-breaching  party  describing  the breach;
provided, however, that the foregoing cure right shall not apply for a breach of
Sections II, IV and VII,  whereupon the  non-breaching  party may terminate this
AGREEMENT  immediately  upon  written  notice  to the  breaching  party  without
granting the breaching party the right to cure such breach.

     CONFIDENTIAL  INFORMATION  (including  all copies and  derivatives,  in any
     form,  thereof)  disclosed by the other party,  and LICENSEE shall cease to
     use the CONFIDENTIAL INFORMATION of LICENSOR,  provided that LICENSEE shall
     not be prohibited  from using such  CONFIDENTIAL  INFORMATION  in providing
     support  services  for the  LICENSED  PRODUCTS  and  selling  all  LICENSED
     PRODUCTS and parts therefor that it has on hand at the date of termination;

LICENSOR'S  AGGREGATE LIABILITY TO LICENSOR,  OR ANY THIRD PARTY FOR ANY AND ALL

HEREUNDER  PRIOR TO THE DATE OF THE EVENT  GIVING RISE TO SUCH  LIABILITY.  THIS
LIMITATION SHALL APPLY  NOTWITHSTANDING  ANY FAILURE OF ESSENTIAL PURPOSE OF ANY
LIMITED REMEDY PROVIDED HEREIN.

                                  XII. GENERAL

     12.1 Integration,  Amendments. This AGREEMENT and Exhibits A and B attached
hereto,  represent and constitute the sole, final and entire  agreement  between

writing signed by the duly authorized  officers of both parties,  and supersedes
all prior agreements and  understandings  with respect to the matters covered by
this AGREEMENT.

     or other  addresses  as may be given  from time to time  under the terms of

     12.3  Governing  Law.  This  AGREEMENT  is  entered  into in and  shall  be
governed,  construed and enforced in all respects solely and  exclusively  under
the laws of the State of California,  USA without giving effect to any law which
would result in the  application  of a different  body of law. Any and all suits
hereunder  shall be brought  and  resolved  solely and  exclusively  in, and the
parties  hereby  irrevocably  consent to the exclusive  jurisdiction  and proper
venue of, the state and federal courts located in the County of San Diego, State
of  California,  USA,  and  waive any  objections  thereto  based on any  ground
including  improper  venue or Forum  Non-Conveniens.  The parties agree that any

                                       13



process directed to any of them in any such litigation may be served outside the
State of  California,  USA, with the same force and effect as if the service had
been made within the State of  California,  USA, and that service of process may
be effected in  accordance  with Section 12.2 hereof.  Any decision  rendered by
such court  shall be  binding,  final and  conclusive  upon the  parties,  and a
judgment  thereon  may  be  entered  in,  and  enforced  by,  any  court  having
jurisdiction over the party against which an award is entered or the location of
such party's assets.

     12.4 Injunctive  Relief.  Notwithstanding  anything to the contrary herein,
each party shall be  entitled  to seek  injunctive  or other  equitable  relief,
wherever such party deems appropriate in any jurisdiction,  in order to preserve
or enforce such party's rights for any breach or threatened  breach of the other
party of Sections II, IV or VII. Each party agrees that:  (i) Section II, IV and
VII are  necessary  and  reasonable to protect the other party and its business,
(ii) any violation of these  provisions  could cause  irreparable  injury to the
other party for which money damages would be inadequate,  and (iii) as a result,
the other party will be entitled to seek and obtain  injunctive  relief  against
the breach or  threatened  breach of the  provisions  of  Section  II, IV or VII
without the  necessity of posting bond or proving  actual  damages.  The parties
agree that the remedies set forth in this Section 12.4 are in addition to and in
no way  preclude  any other  remedies or actions that may be available at law or
under this AGREEMENT.

     12.5 Attorneys'  Fees. The prevailing  party in any action or suit shall be
entitled to recover all costs it incurred in  connection  therewith,  including,
without limitation, reasonable attorneys' fees.

     12.6 No Waiver.  The failure of either party to require  performance by the
other party of any  provision  hereof shall not affect its right to require such
performance  at any time  thereafter;  nor shall the waiver by either party of a
breach of any provision  hereof be taken or held to be a waiver of the provision
itself.  Any such waiver or any amendment of this  AGREEMENT  must be in writing
and signed by both parties to be effective.

     12.7 Headings.  Headings  included herein are for convenience only and will
not be used to construe this AGREEMENT.

     12.8  Severability.  If one or more  provisions in this AGREEMENT are ruled
entirely  or  partly  invalid  or  unenforceable  by any  court or  governmental
authority of competent  jurisdiction,  then: (i) the validity and enforceability
of all  provisions  not  ruled  to be  invalid  or  unenforceable  shall  remain
unaffected;  (ii) the effect of such ruling  shall be limited to the body making
the  ruling;   (iii)  the   provision(s)   held  wholly  or  partly  invalid  or
unenforceable  shall  be  deemed  amended,  and the  parties  shall  reform  the
provision(s)  to  the  minimum  extent   necessary  to  render  them  valid  and
enforceable in conformity  with the parties'  intent as manifested  herein;  and
(iv) if the ruling, or the controlling principle of law or equity leading to the
ruling, is subsequently  overruled,  modified, or amended, then the provision(s)
in question,  as originally set forth in this  AGREEMENT,  shall be deemed valid
and enforceable to the maximum extent permitted by the new controlling principle
of law or equity.

     12.9  Independent  Contractors.   The  relationship  between  LICENSEE  and
LICENSOR  is  solely  that of  independent  contractors.  Neither  party nor its

                                       14



employees,  agents or  representatives  shall be considered  employees,  agents,
partners,  franchisees,  joint venturers or  representatives of the other party.
Neither  party shall act or represent  itself,  directly or by  implication,  as
agent, party to a joint venture with the other party,  partner or representative
of the  other,  or in any  manner  assume or  attempt  to  assume or create  any
obligation or liability of any kind, express or implied, on behalf of, or in the
name of, the other.

     12.10 Export Controls. LICENSEE understands that the LICENSED TECHNOLOGY is
subject  to the  export  control  laws  and  regulations  of the  U.S.  or other
applicable  jurisdictions.  LICENSEE agrees that it will not export or re-export
the LICENSED TECHNOLOGY in violation of such laws or regulations.

     12.11 Corrupt Practices.  LICENSEE shall not, directly or indirectly, make,
offer or agree to make or offer on behalf of LICENSOR,  any loan, gift, donation
or other payment,  directly or  indirectly,  whether in cash or in kind, for the
benefit of or at the direction of any  candidate,  committee,  political  party,
political  function or government or government  subdivision,  or any individual
elected,  appointed or otherwise  designated as an employee or officer  thereof,
for the purposes of influencing any act or decision of such entity or individual
or inducing  such entity or  individual to do or omit to do anything in order to
obtain or retain  business or other  benefits in violation of the United  States
Foreign Corrupt Practices Act.

     12.12 Boycott. LICENSEE shall not, directly or indirectly,  take any action
that would cause LICENSOR to be in violation of United States  anti-boycott laws
under the United States Export  Administration Act or the United States Internal
Revenue Code, or any regulation thereunder.

     12.13  Counterparts.  This  AGREEMENT  may  be  executed  in  one  or  more
counterparts,  each  of  which  shall  be an  original  and all of  which  shall
constitute together the same document.

     12.14 Interpretation. This AGREEMENT has been negotiated by the parties and
their  respective  counsel.   This  AGREEMENT  will  be  fairly  interpreted  in
accordance  with its terms and  without any strict  construction  in favor of or
against any party.  Any ambiguity will not be  interpreted  against the drafting
party.

IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  their duly  authorized
representatives to execute this AGREEMENT.
