(hereinafter "JMAR"). PointSource and JMAR are referred to herein individually
as a "Party" and collectively as the "Parties."

                                  WITNESSETH:

            WHEREAS, PointSource has designed and developed proprietary systems

rights relating to the PointSource Technology; and

            WHEREAS, subject to the terms and conditions contained herein, JMAR
desires to obtain a license from PointSource that would allow JMAR to utilize
PointSource's Intellectual Property rights to manufacture, market and sell the
PointSource Technology and components thereof; and

            WHEREAS, the parties have previously entered into a Letter
Agreement, dated January 7, 2005 (the "Letter Agreement") setting forth key
terms and conditions under which such a license shall be granted.

            NOW THEREFORE, in consideration of the premises and of the

and otherwise dispose of Licensed Products; and

            2.1.2 to grant Sublicenses of such license rights to a third party,

of this License Agreement.

      2.3 SUBLICENSES. During the Term of this License Agreement and subject to
the terms and conditions contained herein, JMAR may grant Sublicenses to a
sublicensee, provided that:

            2.3.1 Sublicenses granted hereunder shall only be effective when
that third party enters into a sublicense agreement in writing, which sublicense
agreement shall at a minimum contain all of the terms and conditions of this
License Agreement that inure to the benefit and protection of PointSource, shall
preserve the right of PointSource to receive royalties for the acts carried out
thereunder as if such acts were being carried out by JMAR under this License
Agreement, and shall expressly provide that PointSource shall be a third-party
beneficiary of such sublicense agreement with the right to enforce PointSource's
rights and remedies directly against such Sublicensee;

                                       -5-
<PAGE>

            2.3.2 JMAR shall remain responsible for the payment of royalties due
to PointSource as a result of any Sublicensee activities under the Sublicense;

            2.3.3 no Sublicense may be made during any time that JMAR is in

Agreement;

            2.3.4 such Sublicense agreement shall be made using such forms as
may be provided by or approved in writing by PointSource, which approval shall
not be unreasonably withheld;

            2.3.5 such Sublicense agreement shall refer to and incorporate by

            2.3.6 no Sublicense shall be approved by PointSource unless JMAR

sole discretion agrees to allow the Sublicense to continue with respect to a
particular Sublicensee; and (ii) that Sublicensee shall agree to the
substitution of PointSource for JMAR as the grantor of such Sublicense and shall

JMAR under this License Agreement for the licensed activities conducted by
Sublicensee.

3. ROYALTIES TO BE PAID TO POINTSOURCE.

      3.1 UP-FRONT PAYMENT. As partial consideration for the grant of this
exclusive license, JMAR shall provide to PointSource:

            3.1.1 520,000 shares of JMAR fully paid, non-assessable common stock
pursuant to the terms of the Registration Rights Agreement; and

            3.1.2 Warrants to purchase 333,333 shares of JMAR common stock, with
an exercise price of $1.38 per share, and a term of five (5) years, pursuant to
the terms of the Warrant.

      3.2 ROYALTIES. As further consideration for the license granted herein,
JMAR shall pay to PointSource an ongoing royalty, which shall be calculated at
the rate of Two And One-Half Percent (2.5%) of the Net Sales of all Licensed
Products throughout the Term of this License Agreement and any extensions
thereof (including any extensions set forth in Section 13.1).

                                       -6-
<PAGE>

            3.2.1 It is the intention of the parties that the ongoing royalties
in this Section 3.2 will be based on the bona fide prices at which JMAR sells
Licensed Products to third parties in arms length transactions. In the event
JMAR sells, transfers, or otherwise provides a Licensed Product to its
Affiliates (or to any third party in other than an arms-length transaction), the
royalties for such a transaction shall be calculated on the basis of such bona
fide prices irrespective of the actual transaction price or of JMAR's accounting
treatment of such transaction. JMAR shall identify all sales to Affiliates (and
all transactions other than arms-length transactions) separately in the reports
provided to Licensor pursuant to Section 4 hereof.

      3.3 If JMAR in good faith determines that it is no longer using or
required to use the PointSource Intellectual Property Rights, it shall give
written Notice to PointSource of this determination and PointSource shall have
sixty (60) days to confirm JMAR's determination from such date of Notice, at
JMAR's sole expense. At the end of that sixty (60) day period, unless
PointSource disagrees that JMAR is no longer using or required to use the
PointSource Intellectual Property Rights, then the applicable royalty shall be
reduced to one and one-fourth percent (1.25%) for the fifth (5th) and sixth
(6th) year of the Term and the license granted hereunder shall become
non-exclusive.

            3.3.1 Should JMAR make such a determination, JMAR shall, immediately
after providing Notice to PointSource under this Section 3.3, cooperate fully
with PointSource and provide PointSource with access upon reasonable notice and
during normal business hours to any of JMAR's facilities; personnel (including
its employees consultants and advisors); test set-ups and equipment; and any
documents, data, test results, and any other information, items and materials
related to the product(s) in question as may be requested by PointSource to
allow PointSource to effectively evaluate JMAR's determination. Should JMAR fail
to cooperate fully with PointSource in accordance with this Section 3.3, then
the license granted hereunder shall remain exclusive for the Term and any
extensions thereof.

            3.3.2 Any disagreement between JMAR and PointSource regarding
whether JMAR is using the PointSource Intellectual Property Rights under this
Section 3.3 shall be resolved in accordance with the Dispute resolution
procedures set forth in Section 16 of this License Agreement. While the Dispute
under this Section 3.3 is unresolved, JMAR shall pay a reduced royalty of 1.25%
to PointSource, and shall pay the remaining 1.25% royalty into escrow until
final resolution of such Dispute. Upon final resolution of such Dispute,
escrowed funds shall be released to PointSource should it be determined that
JMAR is using or is required to use the PointSource Intellectual Property
Rights, or returned to JMAR should it be determined that JMAR is no longer using
or is not required to use the PointSource Intellectual Property Rights.

      3.4 NO SET-OFF. The obligation of JMAR to pay royalties and payments
hereunder shall be absolute regardless of any claim that JMAR may have or assert
against PointSource now or in the future. JMAR shall not have the right to
set-off, compensate or make any deduction from such royalty payments for any
reason whatsoever.

      3.5 TAXES. JMAR will bear all taxes, duties and other governmental charges
relating to or arising under this License Agreement, including without
limitation, any income taxes, any stamp or documentary taxes or duties,
turnover, sales or use taxes, value added taxes, excise

                                       -7-
<PAGE>

taxes, customs or exchange control duties or any other charges relating to or
on, any royalty payable hereunder. JMAR shall obtain, at its own cost and
expense, all licenses, Reserve Bank, Commercial Bank or other bank approvals,
and any other documentation necessary for the transmission of royalties and all
other payments relevant to JMAR's performance under this Agreement. All
royalties payable under this License Agreement shall be payable to PointSource
in gross amounts without any tax withholding therefrom unless, by operation of
an applicable law, JMAR is required to withhold tax thereon and, by opinion of
JMAR's tax counsel in writing so stating, advises PointSource of such
requirement. In regard to any withholding tax so deducted, JMAR shall furnish
PointSource with proper evidence of the taxes paid. In the event that JMAR
realizes a reduction in its tax liability by reason of a foreign tax credit with
respect to withholding taxes so deducted from royalties payable to PointSource
hereunder, JMAR shall pay to PointSource the amount of such reduction in its tax
liability.

4. PAYMENTS AND RECORDKEEPING.

      4.1 WRITTEN STATEMENT. Not later than forty-five (45) days after the end
of each calendar quarter, JMAR shall provide PointSource with a written
statement specifying for the previous calendar quarter: (1) the total quantity
of Licensed Products produced; (2) the total quantity of Licensed Products sold,
leased or otherwise disposed of; (3) JMAR's model name or type designation
Licensed Products sold, leased or otherwise disposed of; (4) the territory in
which such Licensed Products sold, leased or otherwise disposed of; (5) JMAR's
Net Sales; and (6) the amount of royalties payable thereon. The statement shall
also include a statement under oath by one of JMAR's officers that the data
presented in the written statement is accurate and complete and that all
conditions of this License Agreement have been complied with. Each report shall
be accompanied by payment in full of the royalties shown thereby to be due to
PointSource.

      4.2 FUNDS. All payments to be made hereunder shall be payable in United
States dollars. The payments to PointSource shall be made to PointSource at the
address indicated in the Notice provisions hereof, or to such other place of
business as may be designated by PointSource in writing.

      4.3 INTEREST. In addition to any other remedy available to Licensor, if
any payment due under this License Agreement is delayed for any reason, interest
shall accrue and be payable, to the extent legally enforceable, on such unpaid
principal amounts from and after the date on which the same became due, at a per
annum rate equal to the lower of four (4) percentage points above the prime rate
of interest in effect at the time the late payment was due, as reported by Chase
Manhattan Bank in New York, New York, U.S.A., and the highest rate permitted by
law in the state of California.

      4.4 BOOKS AND RECORDS. JMAR agrees to keep full, clear and accurate
accounts and records reflecting and recording all transactions relating to
Licensed Products in sufficient detail to enable the royalties due hereunder to
be determined and generally to allow such investigation of all its operations
hereunder as may be necessary to determine JMAR's compliance with this License
Agreement and the accuracy of the reports and the statements to be furnished
hereunder. JMAR agrees, upon reasonable notice and during normal business hours,
to make those records

                                       -8-
<PAGE>

available for inspection and audit by authorized representatives of PointSource
at such place or places where those records are customarily kept, and to allow
PointSource to inspect JMAR's manufacturing facilities and products, including
parts, work-in-process and finished goods, to confirm whether the PointSource
Technology has been incorporated into JMAR's products. If the audit of JMAR's
records pursuant to this Section determines that there is any underpayment of
royalties due, the payment due shall be made within five (5) days of notice of
such underpayment. If the underpayment is greater than ten percent (10%) of the
payment due for the audited period, then JMAR shall pay the cost of the audit
plus a penalty equal to ten percent (10%) of the cost of that audit.

5. ADDITIONAL OBLIGATIONS OF JMAR.

      5.1 COMMERCIALIZE TECHNOLOGY. JMAR will use commercially reasonable
efforts to produce, market and sell the Licensed Products under its license
throughout the world. As used in this Section 5.1, "commercially reasonable
efforts" shall mean that JMAR is performing its obligations in a sustained
manner consistent with the efforts other similarly situated companies devote to
significant products of similar market potential derived from internal research
programs. Should JMAR for any reason fail to use commercially reasonable efforts
to produce, market and sell any class of the Licensed Products in any of the
three (3) major territories of North and South America, Europe and Africa, and
Asia within four (4) years of the Effective Date, then the license granted under
the License Agreement for each such class of Licensed Product in each such
territory shall at PointSource's sole discretion become non-exclusive
thereafter.

      5.2 WRITTEN REPORT. Upon the request of PointSource but not more often
than once per calendar year, JMAR shall deliver to PointSource a written report
as to JMAR's efforts and accomplishments during the preceding year in marketing
and selling Licensed Products in various parts of the Licensed Territory and its
commercialization plans for the upcoming year.

6. ADDITIONAL OBLIGATIONS OF POINTSOURCE.

      6.1 TANGIBLE PROPERTY. On the Effective Date, in consideration for the
payment of $1.00, PointSource shall sell and transfer (or cause to be sold and
transferred) to JMAR all right, title and interest of PointSource in and to
Tangible Property. The Tangible Property will be transferred to JMAR, free and
clear of all liabilities, obligations, security interests, liens, encumbrances
and other claims. Notwithstanding the foregoing, in no event shall PointSource
be required to effectuate the transfer of any technology or know-how to JMAR.

            6.1.1 The Parties agree to cooperate fully to ensure that the
computers transferred in this Section 6.1 contain only assignable third party
application software and Scientific Data, and to further ensure that all data,
algorithms or other information that is not Scientific Data or assignable third
party application software is removed from these computers and remains with
PointSource (i.e., the computers are "Scrubbed"). JMAR shall cooperate fully
with Roland Hassanein (or other PointSource designee) and provide full access to
the computers and any reasonably requested assistance to such designee to ensure
that these computers are scrubbed within two weeks of the Effective Date. Until
such time as the computers are Scrubbed

                                       -9-
<PAGE>

to the mutual satisfaction of the Parties, the only access JMAR shall make to
those computers is in the presence of and upon the approval of the PointSource
designee. Nothing contained in this Section 6.1 shall limit or otherwise affect
the right to have Fitzgerald conduct any inspections as provided for in Section
9.3.

      6.2 As set forth in Section 1.17, the Tangible Property does not include
prior versions of the Vigilant product and their associated computers.
PointSource agrees that it shall not, for so long as this License Agreement
remains exclusive, sell, transfer or otherwise provide these prior versions of
the Vigilant product to any competitor of JMAR in the field of the Licensed
Products.

      6.3 NO OBLIGATION. The parties understand and agree that there is no
obligation on the part of PointSource to further develop or commercialize the
PointSource Technology.

7. MUTUAL RELEASE

            7.1.2 PointSource acknowledges that it has been advised by its legal
counsel and is familiar with the provisions of California Civil Code Section
1542, which provides as follows:

               "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
         DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING
         THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
         SETTLEMENT WITH THE DEBTOR."

                                      -10-
<PAGE>

                  Being aware of said code section, PointSource hereby expressly

as any other statutes or common law principles of similar effect.

            7.1.3 PointSource represents and warrants that there has been, and
there will be, no assignment or other transfer of any interest in any of the
PointSource Released Claims released hereunder which they may have against
JMAR's Releasees, or any of them. PointSource agrees to indemnify and hold
JMAR's Releasees, and each of them, harmless from any PointSource Released
Claims, liability, demands, damages, costs, expenses and attorneys' fees
incurred by JMAR's Releasees, or any of them, as a result of PointSource's
breach of the foregoing warranty, provided that any JMAR Releasee seeking such
indemnity notifies PointSource within twenty (20) days after receiving any such
PointSource Released Claim and provides PointSource with control over the
defense and settlement of such PointSource Released Claim.

      7.2 JMAR'S RELEASE OF POINTSOURCE. Effective as of the Effective Date, and
for valuable consideration, the receipt and adequacy of which is hereby
acknowledged, JMAR further hereby releases and forever discharges PointSource
and any of its representatives, officers, directors, employees, shareholders,

Releasees"), of and from any and all manner of action or actions, cause or
causes of action, in law or in equity for indemnity or otherwise, suits, debts,
liens, liabilities, claims, demands, damages, losses, costs, or expenses, of any
nature whatsoever, known or unknown, fixed or contingent, arising up to and
including the Effective Date, of any nature whatsoever (hereinafter called "JMAR
Released Claims"), and including but not limited to all claims which JMAR has
made or could have made against the PointSource Releasees, or which arise out of
or relate in any way to the PointSource Intellectual Property Rights. The
foregoing releases shall inure to the benefit of the PointSource Releasees,
their successors, heirs and assigns.

            7.2.1 Notwithstanding any of the above, JMAR reserves all rights and
remedies against the PointSource and its Affiliates in the event of their
failure to perform their obligations or breach of their representations and
warranties under this License Agreement or any of the Transaction Documents.

            7.2.2 JMAR acknowledges that it has been advised by its legal
counsel and is familiar with the provisions of California Civil Code Section
1542, which provides as follows:

               "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
         DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING
         THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
         SETTLEMENT WITH THE DEBTOR."

                  Being aware of said code section, JMAR hereby expressly waives
any rights it may have under California Civil Code Section 1542, as well as any
other statutes or common law principles of similar effect.

                                      -11-
<PAGE>

            7.2.3 JMAR represents and warrants that there has been, and there
will be, no assignment or other transfer of any interest in any of the JMAR
Released Claims released hereunder which they may have against PointSource's
Releasees, or any of them. JMAR agrees to indemnify and hold PointSource's
Releasees, and each of them, harmless from any JMAR Released Claims, liability,
demands, damages, costs, expenses and attorneys' fees incurred by PointSource's
Releasees, or any of them, as a result of JMAR's breach of the foregoing
warranty, provided that any PointSource Releasee seeking such indemnity notifies
JMAR within twenty (20) days after receiving any such JMAR Released Claim and
provides JMAR with control over the defense and settlement of such JMAR Released
Claim.

8. INTELLECTUAL PROPERTY

      8.1 OWNERSHIP. JMAR acknowledges that PointSource shall remain the owner
of and retains all rights, title and interest (including ownership rights) in
and to the PointSource Intellectual Property Rights and PointSource's
Confidential Information, and that JMAR has no rights therein other than under
the licenses as expressly set forth in this License Agreement. Nothing in this
License Agreement shall be construed, by estoppel, implication or otherwise, to
transfer to JMAR title to, or any ownership interest in, the PointSource
Intellectual Property Rights or any other Intellectual Property of PointSource,
or its Affiliates.

      8.2 PREPARATION, COST. PointSource shall be solely responsible for the
ongoing preparation and prosecution of patent applications and for the
registration or other activities necessary to perfect the PointSource
Intellectual Property Rights.

            8.2.1 In order to retain its rights to the patents included in the
PointSource Intellectual Property Rights, JMAR shall reimburse PointSource for
all costs related to these activities and for any and all maintenance fees,
taxes or annuities associated therewith.

            8.2.2 From time to time, JMAR and PointSource will review and
discuss which maintenance fees and costs to pay, whether to continue to
prosecute specific pending patent applications, and whether to file new patent
applications (including PCT and foreign counterpart applications). In the event
that JMAR decides not to continue to pay a maintenance fee or to take other
action to maintain a particular patent, or decides that it is not in its
interests to continue to prosecute a pending application or to file a new
application, it will give sufficient prior notice to PointSource of this fact to
enable PointSource to pay such cost or fee or to take such action and, effective
upon the giving of such notice, JMAR shall thereupon relinquish all of its
license rights to such patent; provided, however, nothing contained herein shall
affect JMAR's obligation to pay the royalty under Section 3 above.

      8.3 PATENT MARKING. JMAR shall observe all requirements of any applicable
laws in each country with respect to the marking of any product sold, leased or
otherwise disposed of by JMAR, where such product is covered by a claim of a
licensed patent or manufactured using a method claimed by a licensed patent. In
the event that such marking of such a product is not feasible, JMAR shall
communicate such infeasibility in writing to PointSource and all requirements of
any applicable laws with respect to the marking of any packaging and

                                      -12-
<PAGE>

advertising, sales or technical literature pertaining thereto, including without
limitation with words and numbers identifying the patents applicable thereto.

      8.4 INFRINGEMENT. JMAR shall promptly provide Notice to PointSource in
writing of any infringement or misuse of the PointSource Intellectual Property
Rights JMAR suspects or of which JMAR is aware.

            8.4.1 The Parties agree to discuss whether and what action may be
warranted against such violation and if the Parties agree that action is
warranted, JMAR may, so long as exclusivity remains in effect under the License
Agreement, in its discretion take the agreed upon action to enforce the PST
Intellectual Property Rights against such violation.

            8.4.2 If JMAR elects to take any such action, JMAR will do so at
JMAR's sole expense, and fully indemnify PointSource for any claims arising
against PointSource as a result thereof. Any amounts recovered by JMAR, whether
by way of judgment, settlement or compromise, shall be applied in the following
order: (i) to cover JMAR's actual and reasonable costs and fees for the
enforcement of any such action; (ii) to pay PointSource in an amount equal to a
two and one-half percent (2.5%) royalty for any accused products covered by the
action, and (iii) to pay the remainder, if any, to JMAR.

            8.4.3 If JMAR does not, within ninety (90) days after knowledge of
the actual or suspected infringement, commence action directed toward
restraining or enjoining such infringement, and diligently pursue such action
thereafter, PointSource may take any permissible legal actions it deems
necessary or appropriate to enforce PointSource's intellectual property rights
and restrain such infringement at PointSource's sole expense, in which case
PointSource shall be entitled to all amounts recovered whether by way of
judgment, settlement or compromise, and PointSource shall be permitted to grant
a license to the accused infringer under the PST Intellectual Property rights
without any accounting to JMAR and notwithstanding any exclusivity provisions
that may be in effect under this License Agreement.

9. REPRESENTATIONS AND WARRANTIES.

      9.1 MUTUAL REPRESENTATIONS AND WARRANTIES. Each Party hereby represents

      9.3 ADDITIONAL REPRESENTATIONS AND WARRANTIES OF JMAR. As of the Effective
Date, JMAR represents and warrants to PointSource that JMAR (i) has not used any
algorithms developed by Fitzgerald, other than what was already in the public
domain prior to such use through no fault of Gregory Quist, David Drake or the
LXT Group, and (ii) has not used any information covered by any claims in any
unexpired patents issued to Wyatt. In connection with PointSource's due
diligence review of JMAR, JMAR shall permit Fitzgerald to inspect its products
and technology to the extent necessary in order to verify the representation in
(i) above either before or after the Effective Date (but in any event prior to
March 31, 2005) and upon execution of a customary non-disclosure agreement.

10. INDEMNIFICATION

            10.1.1 INDEMNIFICATION BY JMAR. JMAR, at its sole expense, shall
indemnify, defend and hold harmless PointSource and its Affiliates, including
their respective directors, officers, employees, agents, contractors, and
consultants from and against any and all demands, claims, losses, liability,
damages, settlement amounts, costs and expenses (including reasonable attorneys'

or alleged acts, whether of omission or commission, by JMAR or any of their
servants, agents, Affiliates, Sublicensees, employees, consultants or

warranties in Section 9 of this License Agreement or JMAR's manufacture or sale
of Licensed Products or other activities undertaken in connection with this
License Agreement, including but not limited to:

                                      -14-
<PAGE>

            10.1.2 any alleged or actual defect in any Licensed Product,
regardless of whether the action is based upon negligence or strict liability;

            10.1.3 the manufacture, labeling, sale, distribution or

            10.1.4 any alleged or actual violation of any warranty,

            10.1.5 any alleged or actual claim of any broker, finder or agent in

            10.1.6 alleged or actual patent, copyright infringement or trade
secret misappropriation, or any other intellectual property infringement or
misappropriation arising out of the Licensed Products and any part thereof.

      10.2 INDEMNIFICATION BY POINTSOURCE. PointSource, at its sole expense,
shall indemnify, defend and hold harmless JMAR and its Affiliates, including
their respective directors, officers, employees, agents, contractors, and
consultants from and against any and all demands, claims, losses, liability,

fees and expenses) arising out of any action, claim or proceeding made or
brought against them or any of them, for or by reason of any acts or alleged

warranties in Section 9 of this License Agreement.

      10.3 JMAR shall promptly inform PointSource by written Notice of any suit
or claim against JMAR relating to JMAR's performance under this License
Agreement, whether such suit or claim is for personal injury, involves alleged
defects in the Licensed Products manufactured, sold or distributed hereunder, or
otherwise.

11. CONFIDENTIAL INFORMATION.

      11.1 JMAR shall use Confidential Information solely to exercise its rights
or perform its obligations under this License Agreement (the "Purpose") and for
no other purpose. JMAR shall hold the Confidential Information in strict
confidence and shall not disclose, provide or otherwise make available any
Confidential Information to any Person without the express written consent of
PointSource, except that JMAR may disclose Confidential Information to its
employees, contractors, consultants, customers, and suppliers, but only in
accordance with the terms and conditions set forth in Section 11.3.

      11.2 JMAR shall take reasonable measures to protect the secrecy of and
avoid disclosure and unauthorized use of the Confidential Information. Without
limiting the foregoing, JMAR shall take at least those measures that it takes to
protect its own most highly confidential

                                      -15-
<PAGE>

information (but in no event less than reasonable care), to protect the
confidentiality and avoid the unauthorized use, disclosure, publication or
dissemination of the Confidential Information. JMAR shall limit copying and
reproduction of Confidential Information to the minimum required to carry out
the Purpose. JMAR shall include appropriate proprietary rights notices on any
such copies, in the same manner in which such notices were set forth in or on
the original, or add such notices if none were included on the original. JMAR
shall immediately notify PointSource in the event of any unauthorized use or
disclosure of the Confidential Information.

      11.3 JMAR, may disclose the Confidential Information to its employees,
contractors, consultants, customers, and suppliers, but only to those
individuals who have a need to access such Confidential Information (and only
such Confidential Information as they may need) in order for JMAR to exercise
its rights or perform its obligations under this License Agreement, and further
provided that JMAR shall use its best efforts to ensure that such recipients who
shall have access to the Confidential Information shall hold it confidential,
and not disclose the same and not use the Confidential Information except for
the Purpose. Without limiting the generality of the foregoing, JMAR shall inform
each of its contractors, consultants, and employees having access to such
Confidential Information ("Designated Recipients") of such party's limitations,
duties, and obligations regarding disclosure, use and copying of the
Confidential Information, and cause its Designated Recipients to enter into a
secrecy agreement, whether by means of a new or existing agreement, providing
the same or greater protection as provided herein. JMAR shall be and shall
remain liable for any breach of the confidentiality provisions contained herein
by any of its employees, contractors, consultants and suppliers.

      11.4 The obligations of this Section, including the restrictions on
disclosure and use shall not apply with respect to any Confidential Information
to the extent that such Confidential Information: (i) is now publicly available
or becomes available to the public in the future through no act or failure to
act on the part of the Receiving Party and without breach of this License
Agreement (or of any other confidentiality agreement between the Parties); (ii)
the Receiving Party can demonstrate came into its possession in good faith from
a third party who is legally entitled to make such information available without
restriction, and who is not bound by a duty of confidentiality toward the
Disclosing Party; (iii) is at any time developed by the Receiving Party
independently of any such disclosure from the Disclosing Party, and such
independent development can be demonstrated by the Receiving Party; and (iv)
information that the Receiving Party can establish within 30 days of disclosure
by appropriate documentation or other evidence, was already in its possession
prior to the disclosure by the Disclosing Party without breach of any obligation
or other misappropriation. In addition, Receiving Party may use or disclose
Confidential Information for other than the Purpose to the extent (ii) such use
or disclosure is explicitly approved for release by written authorization of the
Disclosing Party, which release shall be in the sole discretion of the
Disclosing Party; or (ii) Receiving Party is legally compelled to disclose such
Proprietary Information, provided, however, that prior to any such compelled
disclosure, Receiving Party shall give Disclosing Party reasonable advance
Notice of any such disclosure and shall cooperate with Disclosing Party in
protecting against any such disclosure and/or obtaining a protective order
narrowing the scope of such disclosure and/or use of the Proprietary
Information.

                                      -16-
<PAGE>

      11.5 The Parties expressly confirm and agree that no public disclosure
with respect to any item of Confidential Information is now required by reasons
of the Securities Exchange Act of 1934, as amended, or the rules and regulations
promulgated thereunder, or similar requirements related to general disclosure.
In the event Receiving Party determines in the future that such disclosure is
required, no such disclosure shall be made unless and until Receiving Party
consults with Disclosing Party regarding the necessity and form of any such
disclosure, and provides Disclosing Party a reasonable opportunity to review the
proposed disclosure and comment thereon, and that such disclosure shall be
redacted to the reasonable satisfaction of both Parties.

      11.6 All documents and information relating to Confidential Information
delivered to JMAR are and shall remain the property of PointSource. Within sixty
(60) days after the termination of this License Agreement for any reason, JMAR
shall deliver to PointSource or its designee all documents and other information
in tangible form furnished to JMAR by PointSource or created by JMAR as a result
of information furnished to JMAR by PointSource including all copies thereof,
which incorporate or reflect the PointSource Intellectual Property Rights or any
other Confidential Information; or (at the option of JMAR with the prior written
approval of PointSource) in the case of any such documents or other items
created by JMAR as a result of information furnished to JMAR by PointSource, a
certificate from JMAR's Chief Executive Officer certifying that all such
documents or items, and all copies thereof, have been destroyed. Upon
termination, Receiving Party shall not use the Proprietary Information in any
way for any purpose.

      11.7 JMAR acknowledges and agrees that PointSource would suffer
irreparable harm for which monetary damages alone would be an inadequate remedy
if there were a breach of obligations under this Section 11. JMAR further
acknowledges and agrees that PointSource would be entitled to equitable relief,
including injunctive relief, in addition to any other remedies available, to
protect PointSource's rights and interests if such a breach were to arise, were
threatened, or were asserted.

      11.8 On all copies of the PointSource Intellectual Property Rights made by
JMAR pursuant to this License Agreement, JMAR agrees that it shall (i) not
remove any copyright notices, trademarks, or other proprietary legends contained
therein or thereon, as provided by PointSource, and (ii) include any copyright
notices, trademarks, or other proprietary legends contained within the
PointSource Technology, as provided by PointSource.

      11.9 Each Party will provide notice to the other Party immediately after
learning of, or having reason to suspect, a breach of any of the confidential
restrictions set forth in this Section or elsewhere in this License Agreement.

      11.10 The parties have previously entered into a confidentiality agreement
dated January 12, 2005 (the "Confidentiality Agreement"). The Parties agree that
the confidentiality provisions of this License Agreement shall supersede that
prior Confidentiality Agreement.

      11.11 The provisions of this Section 11 shall survive the termination of
this License Agreement for any reason whatsoever.

                                      -17-
<PAGE>

12. PUBLICITY

      12.1 Within ten (10) days of the Effective Date, the Parties shall agree
in good faith on a form of press release which JMAR may release any time
thereafter.

      12.2 The Parties agree to keep the terms and conditions of this License
Agreement confidential, except either Party may:

            12.2.1 acknowledge the existence of this License Agreement;

            12.2.2 disclose the Agreement in confidence to existing or
prospective investors or acquirers and investment bankers and related financial
service providers; and

            12.2.3 make disclosure of the terms and conditions of this License
Agreement if considered a "material" agreement under federal laws or SEC rules
or regulations. Any copy of this License Agreement to be filed with the
Securities and Exchange Commission under this Section shall be redacted to the
reasonable satisfaction of both Parties; provided, however, in the event that
the Securities and Exchange Commission objects to the redaction of any portion
of the Agreement after the initial submission, JMAR shall inform PointSource of
the objections and shall in good faith respond to the objections and use
commercially reasonable efforts to limit the disclosure required by the
Securities and Exchange Commission.

            12.2.4 make disclosure of the terms and conditions of this License
Agreement if such disclosure is in response to a court order or regulation of a
governmental body provided, however, that either Party prior to such disclosure
pursuant to such law, order or regulation shall first have promptly informed the
other Party of such law, order or regulation and made reasonable efforts to
obtain a protective order and/or appropriate confidentiality provisions
requiring that such information to be disclosed be used only for the purpose for
which such law, order or regulation was issued.

      12.3 Nothing in this License Agreement shall be construed as conferring
upon either Party any right to include or use in advertising, packaging or other
commercial activities related to a Licensed Product, any reference to the other
Party or its Affiliates, their trade names (other than the name Vigilant),
trademarks or service marks in a manner that would be likely to cause confusion
or to indicate that such Licensed Product is in any way certified by the other
Party hereto or its Affiliates.

13. TERM AND TERMINATION.

      13.1 INITIAL TERM. The License shall remain in effect for a period of six
(6) years following the Effective Date (the "Term"). The parties may extend the
term of the License Agreement beyond this six (6) year period, provided that:
(i) JMAR provides PointSource with Notice of a request for such extension at
least six (6) months prior to the expiration of the Term; (ii) such extension
shall be under the same terms and conditions as set forth herein (other than the
initial stock and warrant payment as set forth in Section 3.1); and (iii) the
parties shall have negotiated and agreed in writing upon a mutually acceptable
amendment to the License providing

                                      -18-

for minimum royalties and appropriate remedies with respect thereto prior to the
fourth anniversary of the Effective Date.

License Agreement shall be and become terminated immediately upon written Notice
of termination from PointSource to JMAR for any of the following events:

            13.2.1 JMAR fails to pay the royalties to be paid pursuant to
Section 3 or any other amounts due to PointSource hereunder when those payments
are due and does not make that payment within thirty (30) days after Notice of
default is given to JMAR;

            13.2.2 JMAR makes any purported assignment of this License Agreement
or grants any purported sublicense under this License Agreement in violation of
the provisions of Sections 2.3 or 21 and of this License Agreement;

            13.2.3 JMAR materially breaches any other provision of this License
Agreement and shall not cure that violation within sixty (60) calendar days
after Notice thereof by PointSource;

            13.2.4 if JMAR shall be adjudged bankrupt or insolvent by a court of
competent jurisdiction or an order shall be made by a court of competent
jurisdiction for the appointment of a receiver, liquidator or trustee of JMAR or
of all or substantially all of its property by reason of the foregoing, or
approving any petition filed against JMAR for its reorganization under the
bankruptcy laws, and such adjudication or order shall remain in force for a
period of thirty (30) days;

            13.2.5 if JMAR shall institute proceedings for voluntary bankruptcy
or shall file a petition seeking reorganization under the federal bankruptcy
laws, or for relief under any law for the relief of debtors, or shall consent to
the appointment of a receiver for itself or of all or substantially all of its
property, or shall make a general assignment for the benefit of its creditors,
or shall admit in writing its inability to pay its debts generally, as they
become due;

            13.2.6 In the event that JMAR or any of its Affiliates initiates any
judicial proceeding or administrative action or proceeding (including
arbitration, International Trade Commission, and similar proceedings, in the
form of interferences in the Patent and Trademark Office or an action under 35
U.S.C. Section 146 or 256 (or any foreign equivalent thereof)) to challenge the
validity and/or enforceability of any PointSource Patent Right, PointSource may,
at its option, (i) terminate JMAR's license to such challenged patents, or (ii)
terminate this License Agreement, in each case on written notice to JMAR, it
being expressly agreed that neither JMAR nor its Affiliates may enjoy a license
to such patent(s) while at the same time seeking to invalidate or render such
patent unenforceable. The parties agree, however, that no right of termination
under this section shall arise if the challenge is (a) in response to or defense
of an action initiated by PointSource, or (b) required by virtue of a
contractual obligation to indemnify a third party in a patent infringement
action initiated by PointSource.

Agreement shall be and become terminated immediately upon written Notice of
termination from JMAR to PointSource in the following events:

License Agreement and shall not cure that violation within thirty (30) days
after Notice thereof by JMAR;

            13.4.2 if PointSource shall be adjudged bankrupt or insolvent by a
court of competent jurisdiction or an order shall be made by a court of
competent jurisdiction for the appointment of a receiver, liquidator or trustee
of PointSource or of all or substantially all of its property by reason of the
foregoing, or approving any petition filed against PointSource for its
reorganization under the bankruptcy laws, and such adjudication or order shall
remain in force for a period of thirty (30) days; or

            13.4.3 if PointSource shall institute proceedings for voluntary

      13.5 NOTICE TO JMAR. PointSource agrees that if any of the events

the Confidential Information that is in its possession, custody or control, and
certify in writing within five (5) business days thereafter that it has complied
with the foregoing obligation. The Parties shall remain liable for the reporting
and payment of all payments due or which may become due under this License
Agreement after its termination or expiration.

      13.8 TERMINATION WITHOUT PREJUDICE. The termination of this License
Agreement for any reason shall:

            13.8.1 be without prejudice to PointSource' right to receive all
payments due under the terms of this License Agreement to the date of its
termination;

                                      -20-

      14.1 EACH PARTY ACKNOWLEDGES AND AGREES THAT ALL INTELLECTUAL PROPERTY AND
ANY OTHER INFORMATION OR MATERIALS LICENSED OR PROVIDED HEREUNDER (INCLUDING THE

PRODUCTS, THE TANGIBLE PROPERTY, OR OTHERWISE UNDER THIS AGREEMENT, REGARDLESS
OF THE FORM OF ACTION, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT
PRODUCT LIABILITY, OR OTHERWISE, EVEN IF POINTSOURCE HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

      14.3 TO THE MAXIMUM EXTENT ALLOWED UNDER APPLICABLE LAW, IN NO EVENT SHALL
POINTSOURCE'S AGGREGATE LIABILITY TO JMAR, OR ANY THIRD PARTY FOR ANY AND ALL

POINTSOURCE 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.

15. DISCLAIMER OF WARRANTY

      15.1 EXCEPT AS EXPRESSLY PROVIDED IN SECTION 9, NEITHER PARTY MAKES ANY
WARRANTY, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY, OR
FITNESS FOR A PARTICULAR PURPOSE, OR ARISING FROM A COURSE OF DEALING, USAGE, OR
TRADE PRACTICE.

<PAGE>

      15.2 Nothing in this License Agreement shall be construed as:

            15.2.1 a warranty or representation by PointSource as to the scope,
coverage, validity or enforceability, of any Intellectual Property licensed
hereunder; or

            15.2.2 a warranty or representation by PointSource that any

Products hereunder will be free from infringement or claims of infringement of
any Intellectual Property right of third parties; or

            15.2.3 a requirement that PointSource shall file any Patent

            15.2.4 an agreement or any authorization by PointSource to bring or
prosecute actions or suits against third parties for patent infringement or

            15.2.5 conferring any right to JMAR to use in advertising,
publicity, or otherwise, any trademark, service mark, trade name or names, or
any contraction, abbreviation, or simulation thereof, except for the name
Vigilant.

16. DISPUTE RESOLUTION.

      16.1 DISPUTES. The handling and resolution of any and all disputes, claims
and causes of action of any nature whatsoever arising from or in connection with
this License Agreement (the "Dispute") shall be governed exclusively by and
settled in accordance with the provisions of this Section 16.

      16.2 NEGOTIATION. The Parties shall make a good faith attempt to resolve
any Dispute arising out of or relating to this License Agreement through
informal negotiation between appropriate representatives from each party. Within
thirty (30) days after Notice of a Dispute is given by either Party to the other
Party, representatives of each Party with the authority to resolve the Dispute
shall meet and make a good faith attempt to resolve such dispute and shall
continue to negotiate in good faith in an effort to resolve the Dispute or
renegotiate the applicable section or provision without the necessity of any
formal proceedings. If after sixty (60) days from the first Notice of a Dispute
either Party feels that such negotiations are not leading to a resolution of the
Dispute, such Party may send a Notice to the other Party describing the Dispute
and requesting a meeting of the senior executives from each Party. Within ten
(10) business days after this second Notice of a Dispute is given, appropriate
senior executives (V.P. level or higher) of each Party who shall have the
authority to resolve the Dispute shall meet to attempt in good faith to
negotiate a resolution of the Dispute prior to pursuing other available
remedies.

      16.3 INFORMATION REQUESTS. During the course of negotiations under Section
16.2, any and all reasonable requests made by one Party to the other for
information, including requests for copies of relevant documents, shall be
honored by the other Party. The specific format for such information will be
left to the reasonable discretion of the designated negotiating senior

                                      -22-
<PAGE>

executives of the Parties, and may include, for example, the preparation of
agreed upon statements of fact or written statements of position furnished to
the other party.

      16.4 MEDIATION. In the event that any Dispute is not settled by the
Parties within thirty (30) days after the first meeting of the negotiating
senior executives, the Parties will attempt in good faith to resolve such
Dispute by nonbinding mediation using a mediator employed by JAMS, with the
specific mediator agreed to by the parties. The mediation shall be held at a
mutually agreeable location in San Diego, and be held within thirty (30) days of
the end of such thirty (30) day negotiation period. Except as provided below in
Section 16.6, no litigation for the resolution of such dispute may be commenced
until the Parties try in good faith to settle the Dispute by such mediation in
accordance with this Section and either Party has concluded in good faith that
amicable resolution through continued mediation of the matter does not appear
likely. The costs of mediation shall be shared equally by the Parties to the
mediation. Any settlement reached by mediation shall be recorded in writing,
signed by the Parties, and shall be binding on them.

      16.5 LEGAL PROCEEDINGS. In the event that any Dispute is not settled by
the Parties through mediation as outlined in Section 16.4, either Party may
institute legal proceedings for that Dispute in a court of competent
jurisdiction.

      16.6 RELIEF. Notwithstanding anything else to the contrary contained in
this Section 16, a Party is not required to follow these dispute resolution
mechanisms prior to seeking relief from a court of competent jurisdiction where
the subject Dispute involves: (i) nonpayment of royalties or other payments due
to PointSource hereunder; (ii) breach of any obligation of confidentiality;
(iii) an infringement, misappropriation, or misuse of any intellectual property
right; or (iv) any other claim where interim relief from the court is sought to
prevent serious and irreparable injury to a party. Provided, however, that the
Parties shall make a good faith effort to negotiate such Dispute while such
court action is pending.

      16.7 ATTORNEYS FEES. The prevailing Party in any litigation arising out of
the License Agreement shall be entitled to reasonable attorneys' fees, with the
amount thereof to be determined by the court.

      16.8 CONTINUED OBLIGATION. Unless otherwise agreed in writing, both
Parties shall continue to provide service and honor all other commitments and
obligations as set forth in this License Agreement, and any amendments hereto,
during the course of Dispute resolution with respect to all matters not subject
to such Dispute.

17. LIMITATIONS ON LIABILITY

      17.1 EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS LICENSE AGREEMENT, IN
NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR LOST PROFITS OR FOR
ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR EXEMPLARY DAMAGES ARISING
FROM THE SUBJECT MATTER OF THIS LICENSE AGREEMENT, REGARDLESS OF THE TYPE OF
CLAIM AND EVEN IF THAT PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF

                                      -23-
<PAGE>

SUCH DAMAGES. EACH PARTY ACKNOWLEDGES THAT THE MUTUAL LIMITATIONS OF LIABILITY
CONTAINED IN THIS SECTION REFLECT THE ALLOCATION OF RISK SET FORTH IN THIS
LICENSE AGREEMENT AND THAT EACH PARTY WOULD NOT ENTER INTO THIS LICENSE
AGREEMENT WITHOUT THESE LIMITATIONS ON LIABILITY.

18. INSURANCE.

      18.1 Without limiting JMAR's liability pursuant to the indemnity
provisions of this License Agreement, prior to the date on which JMAR shall
first install a beta or other version of the Licensed Products in a customer's
facility or otherwise sell, license or dispose of a Licensed Product, JMAR shall
obtain and thereafter maintain commercial products liability insurance in the
amount of at least $1,000,000 per occurrence. Said insurance coverage shall be
written on a "claims made" or "occurrence" basis.

      18.2 The insurance described in this Section 18 shall include: (1) an
endorsement stating that PointSource shall receive at least thirty (30) days
written notice prior to cancellation or non-renewal of coverage, with exception
of a 10 day notice of cancellation for non-payment; and (2) an endorsement
naming PointSource as an additional insured.

      18.3 All insurance shall be obtained from an insurance company of
recognized financial responsibility. JMAR shall give at least thirty (30) days
prior written notice to PointSource of the cancellation of, or any modification
in, such insurance policy that would affect PointSource's status or benefits
thereunder, with exception of a 10 day notice of cancellation for non-payment.
This insurance may be obtained for PointSource by JMAR in conjunction with a
policy which covers products other than the Licensed Products.

      18.4 No later than thirty (30) days from the effective date hereof, JMAR
shall furnish to PointSource evidence, in form and substance satisfactory to
PointSource, of the maintenance and renewal of the required insurance including,
but not limited to, copies of policies with applicable riders and endorsements,
and certificates of insurance.

      18.5 The insurance set forth in this Section must cover all countries in
which JMAR sells, transports, manufactures or maintains inventory of Licensed
Products.

19. GOVERNING LAW; VENUE AND JURISDICTION.

      This License Agreement will be governed by, subject to, and construed in
accordance with the internal laws of the State of California, without reference
to its conflicts of laws provision, as such laws apply to contracts between
California residents performed entirely within California. Venue for any dispute
however arising under this License Agreement shall be in San Diego California
and both Parties hereby consent to the jurisdiction of the State and Federal
Courts in San Diego, California. The Parties agree that the United Nations
Convention on Contracts for the International Sale of Goods will not apply to
this License Agreement.

                                      -24-

20. RELATIONSHIP OF THE PARTIES.

      20.1 Under this License Agreement (i) each Party will be deemed to be an
independent contractor and not an agent, joint venturer, or representative of
the other Party; (ii) neither Party may create any obligations or
responsibilities on behalf of or in the name of the other Party; and (iii)
neither Party will hold itself out to be a partner, employee, franchisee,
representative, servant, or agent of the other Party. Nothing contained in this
License Agreement shall be deemed to create any partnership, joint venture,
association or syndicate among or between the Parties, and nothing herein
contained shall give, or is intended to give, any rights of any kind to any
third persons.

      20.2 In addition, without limiting the generality of Section 20.1, JMAR
agrees not to in any way misrepresent, or to mislead any third party (especially
with respect to prospective customers, journalists, or market analysts, etc.)
about JMAR's relationship with PointSource or regarding the features of the
PointSource Technology, including any technical specifications or expected
benefits of use. In particular, JMAR shall not represent itself as an exclusive
distributor of PointSource' products, and shall not represent itself as the
developer or manufacturer of PointSource' products, or as PointSource itself.

21. ASSIGNABILITY.

      21.1 ASSIGNABILITY IN GENERAL. Neither Party shall assign or transfer this
License Agreement or all or any part of its rights or obligations hereunder, by
operation of law or otherwise, without the prior written consent of the other
Party, except that PointSource may assign its rights and obligations under this
License Agreement to a Permissible Transferee as that term is defined in the
Securities Purchase Agreement. Notwithstanding the foregoing and provided such
entity is not a competitor of the other Party, either Party may assign this
License Agreement in whole or in part (i) to any Subsidiary; or (ii) to a
successor of such Party in the event of a merger or acquisition of all or
substantially all of the assets of such Party; (iii) to a successor of any
portion of the business of such Party resulting from a divestiture of such
business; or (iv) to a successor of such Party as a result of a foreclosure
action instituted against that Party. Any unauthorized assignment or transfer
shall be null and void. This License Agreement shall be binding upon and inure
solely to the benefit of each Party and its successors and permitted assigns.

      21.2 ASSIGNABILITY BY POINTSOURCE. Notwithstanding the foregoing,
PointSource may, without the consent of JMAR, assign this License Agreement to
any person, firm or corporation which shall acquire all or substantially all of
the PointSource Patent Rights and PointSource Technology relating to this
License Agreement.

      21.3 ASSUMPTION BY ASSIGNEE. No assignment of this License Agreement shall
be valid until and unless this License Agreement shall have been assumed by the
assignee in writing. When assigned in accordance with the foregoing, this
License Agreement shall be binding upon and shall inure to the benefit of the
assignee, however, the assignor shall not be released from any duties,
obligations or liabilities under this License Agreement unless such release is
expressly made in writing by the releasing Party.

23. WAIVER.

      No waiver, amendment or modification of this License Agreement shall be
effective unless made in writing and signed by both parties. Failure or delay of
a Party to demand performance of any of the terms and conditions, or to exercise
any of its rights, powers, remedies or privileges under this License Agreement,
will not constitute a waiver of such terms, conditions, rights, or privileges.

24. ENTIRE AGREEMENT.

      This License Agreement, the Exhibits hereto, and the Transaction
Documents, each as amended from time to time, constitute the entire
understanding and agreement between the parties in relation to the subject
matter hereof and, unless otherwise expressly provided in this License
Agreement, supersede all prior discussions, negotiations, agreements and
representations related to this subject matter, whether oral or written and
whether or not executed by a Party. No

                                      -26-
<PAGE>

modification, amendment or other change may be made to this Agreement or any
part thereof unless reduced to writing and executed by authorized
representatives of all Parties.

25. COMPLIANCE WITH LAW

      The Parties will at all times comply with all applicable foreign, U.S.,
state, and local laws, rules and regulations relating to the execution, delivery
and performance of this License Agreement. Each Party agrees that it will not
export or reexport, resell, ship, provide, or divert or cause to be exported or
reexported, resold, shipped, provided, or diverted directly or indirectly any
PointSource Technology, in whole or in part, whether or not it is Confidential
Information, nor provide or furnish any material or service to any country or to
any person or entity, where such activity is prohibited or otherwise restricted
by any applicable U.S. regulation or statute, or by any foreign sovereign
government with competent jurisdiction, or for which an export license or other
governmental approval is required, without prior written consent (or export
license), as required, of the Bureau of Export Administration of the U.S.
Department of Commerce, or other such governmental entity as may have
jurisdiction over such export or transmission.

26. SEVERABILITY.

      In the event any provision of this License Agreement or the application of
such provision to any particular facts or circumstances is held to be invalid,
unenforceable or contrary to law by any court of competent jurisdiction, then:
(i) the validity and enforceability of such provision or provisions as applied
to any other particular facts or circumstances shall not in any way be affected
or impaired thereby; (ii) the remaining provisions of this License Agreement
shall remain in full force and effect as if the invalid portion was never a part
of this License Agreement when it was executed; and (iii) such provision or
provisions will be reformed without further action by the Parties and only to
the extent necessary to make such provision or provisions valid and enforceable
when applied to such particular facts and circumstances. Should the severance of
any such part of this License Agreement materially affect any other rights and
obligations of the parties hereunder, the parties shall negotiate in good faith
to amend this License Agreement to effectuate the original intent of both
Parties in a manner satisfactory to the Parties.

27. COUNTERPARTS AND FACSIMILE.

      This License Agreement may be executed in any number of counterparts, each
of which when so executed and delivered will be deemed an original, and such
counterparts together will constitute one and the same instrument. The Parties
intend that each Party will receive a duplicate original of the counterpart copy
or copies executed by it. This License Agreement may be executed and delivered
by telecopier with the same force and effect as if it were a manually executed
and delivered counterpart.

28. FORCE MAJEURE

      Neither Party shall be liable for failure or delay in performance of its
obligations under this License Agreement, nor will it be deemed in default or
breach of any provision of this

                                      -27-
<PAGE>

License Agreement by reason thereof, to the extent such failure or delay is
caused by an act of God, act of a public enemy, war or national emergency,
rebellion, insurrection, riot, epidemic, quarantine restriction, fire, flood,
explosion, storm, earthquake, or other catastrophe. If a Party's performance
under this License Agreement is affected by a force majeure event, such Party
shall give prompt written notice of such event to the other Party and shall at
all times use its reasonable commercial efforts to mitigate the impact of the
force majeure event on its performance under this License Agreement.
