Licensed Technology (the “Assumed Liabilities”).

3.4. Excluded Assets and Excluded Liabilities. JMAR shall not assume any
liabilities, obligations or commitments of Quist or Drake (the “Excluded
Liabilities”) relating to or arising out of the business, products, services,
operations, assets, properties, taxes or deferred taxes of Quist or Drake on or
prior to the Closing, other than the Assumed Liabilities. Quist and Drake are
not transferring or licensing any asset, right or property not specifically

3.5. Consideration. In consideration for the transfer, conveyance, assignment,
license and delivery by Quist and Drake of the Transferred Technology and
Licensed Technology to JMAR, Quist and Drake shall receive payments (the “CORTS
Payments”) equal to two percent (2%) of the gross revenue of any nature arising
from any CORTS System regardless of the technology employed (the “CORTS
Revenue”), commencing on the date on which JMAR receives from unaffiliated third
parties the first dollar of CORTS Revenue (the “Revenue Start Date”) and
continuing until the seventh anniversary thereof (the “Revenue End Date”). In
addition, the One Hundred Twenty Five Thousand Dollar ($125,000) loan JMAR made
to Quist and Drake pursuant to the Alliance Agreement between them dated as of
June 10, 2004 (the “Loan”) shall be satisfied solely from CORTS Payments that
are generated from revenues of any nature from any CORTS System received after
the third anniversary of the Revenue Start Date, and shall be repaid by payment
of 50% of each CORTS Payment due thereafter until repaid in full. If, on the
Revenue End Date, the Loan has not been repaid in full, the remaining unpaid
portion of the Loan shall then be forgiven. On the Closing Date, the Loan shall
be amended to provide that interest shall begin accruing on April 2, 2005 at the
prime rate quoted by the Western edition of the Wall Street Journal (the “Prime
Rate”) until satisfied or discharged. Quist and Drake may prepay the Loan
without penalty.

(a) Payments. Each CORTS Payment shall be paid in arrears within forty-five
(45) days after the end of each calendar quarter commencing with the first
quarter in which the Revenue Start Date occurs, and shall be accompanied by a
true and accurate written report signed and certified to be correct by the Chief
Financial Officer or Chief Executive Officer of JMAR setting forth the amount of
revenue received, the nature of the receipts, and the basis upon which the CORTS
Payment has been calculated. Any CORTS Payment not timely paid shall accrue
interest at the Prime Rate.

(b) Audit. JMAR shall keep full, true and accurate records and books of account
containing all particulars that may be necessary for the purpose of calculating
the CORTS Payments. These records and books of account shall be kept by JMAR at
its usual place of business and such books and the supporting data shall be
retained for at least six (6) years following the end of the calendar year to
which they pertain. Quist and Drake shall have the right on ten (10) days prior
written notice, to audit such books and records at JMAR’s usual place of
business following the end of the calendar year. If any audit discloses
underpayment of the CORTS Payment exceeding ten percent (10%) for the audited
period, JMAR shall pay the cost of the audit, plus the amount of the
underpayment with interest at the rate at the lesser of the Prime Rate or the
maximum rate permitted by law, plus a penalty equal to ten percent (10%) of any
underpayment. Otherwise, Quist and Drake shall bear the cost of such audit.

of its business relating to CORTS or the CORTS System, then Quist and Drake
shall have the option to elect one of the following (i) the express assumption
by the buyer of the JMAR’s obligations to make the CORTS Payments, or (ii) a
lump sum payment (the “Alternative Payment”) by JMAR equal to 2% of the present
value of the stream of “Projected Revenues” calculated for the period remaining
until the Revenue End Date (as defined in Section 3.5 above). For purposes of
this Section 8.1, the “Projected Revenues” shall be determined as follows:

  1.   The “Post-Closing Quarters” is equal to the number of calendar quarters
between the date of the closing of the sale of the business relating to CORTS or
the CORTS System and the Revenue End Date;

  2.   The “Projected Revenues” for the Post-Closing Quarters shall be
determined, where possible, by using the actual historical quarterly revenues
for the same number of quarters before the closing of the sale of the business
relating to CORTS or the CORTS System as is equal to the number of Remaining
Quarters;

  3.   For purposes of calculating the present value of the Projected Revenues,
the discount rate shall be 25%; and

  4.   The Alternative Payment shall in no event be in excess of 5% of the Net
Proceeds received or receivable on account of such sale or transfer. Net
Proceeds shall mean the gross amounts received less the costs of sale, exclusive
of transfer or other taxes.

b. In the event of a sale, merger or other transfer of the stock or assets of
JMAR, the acquiring party (or surviving party in a merger) shall be required to
assume JMAR’s obligations under this Agreement.

8.2. Further Agreements of Quist and Drake and JMAR. Quist and Drake shall, upon
the reasonable request of JMAR from time to time, execute and deliver to JMAR
such further bills of sale, endorsements and other good and sufficient
instruments of transfer and assignment, as may be necessary or desirable in
order to vest in JMAR all right, title and interest in and to any and all of the
Transferred Technology to the extent contemplated by this Agreement. Quist and
Drake and JMAR agree to cooperate in order to obtain all necessary consents to
the transfer to JMAR of any rights constituting part of the Transferred
Technology.

8.3. Mutual Releases. Quist and Drake on the one hand and JMAR on the other, on
their own behalf and on behalf of each of their respective agents, employees,
partners, joint venturers, Affiliates, subsidiaries, directors, officers,
shareholders and all persons acting by or through them, including their
respective successors and assigns, irrevocably, unconditionally and fully
release, acquit and forever discharge the other, and each of their respective
agents, employees, partners, joint venturers, Affiliates, subsidiaries,
directors, officers, shareholders and all persons acting by or through them,
including their respective successors and assigns, from any and all charges,
complaints, claims, liabilities, obligations, promises, agreements,
controversies, damages, actions, causes of action, suits, rights, demands,
costs, losses, debts and expenses of any nature whatsoever, known or unknown,
suspected or unsuspected, that the releasing party may have against the released
party including without limitation those arising out of alleged breaches of
representations, warranties or covenants set forth in the Original Agreement,
the Alliance Agreement or respecting the Transferred Technology or the Licensed
Technology based on facts occurring before the Effective Date (collectively, the
“Claims”). Despite the preceding, nothing in this Agreement is to be construed
as a release or waiver of any Claims Quist or Drake may have against PointSource
Technologies, LLC or any of its Affiliates or successors and assigns, or Baker
and MacKenzie.

Each of the Drake and Quist on the one hand and JMAR on the other expressly
waives and relinquishes all rights and benefits they may have under Section 1542
of the Civil Code of the State of California or any other applicable state law
relating to general releases. California Civil Code Section 1542 reads as
follows:

§1542. [General Release — Claims Extinguished.] 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.

Each of the Drake and Quist on the one hand and JMAR on the other represent that
they have not previously assigned nor transferred in any manner, or purported to
have assigned or transferred in any manner, any of the Claims, nor has any such
assignment or transfer occurred as a consequence or by operation of law.

9. Survival of Representations and Warranties of Quist and Drake and JMAR. All
representations and warranties of JMAR, on the one hand, and Quist and Drake, on
the other, in the Transaction Documents shall survive the Closing and shall
expire and be deemed terminated and extinguished on the second anniversary of
the Closing Date. The covenants of the parties shall survive the execution and
delivery of this Agreement until they are performed in full.

10. Indemnification.

10.1. Obligation of Quist and Drake. Subject to the limitation on Quist and
Drake’s liability under Section 10.4 below, Quist and Drake agree to indemnify,
defend and hold harmless JMAR and its directors, officers, employees, agents,
subsidiaries and Affiliates, and their respective successors and assigns from
and against all losses, liabilities, damages, deficiencies, costs or expenses,
including interest, penalties and reasonable attorneys’ fees and disbursements
(“Losses”) which any of them shall incur or suffer based upon, arising out of or
otherwise in respect of or involving (a) any inaccuracy in or any breach of any
representation, warranty, covenant or agreement of Quist and Drake contained in
the Transaction Documents which was not waived by JMAR prior to Closing, or
(b) any liability, obligation, debt or commitment of Quist and Drake, not
included in the Assumed Liabilities, or (c) any third-party claim or claims made
or threatened against JMAR or affecting any portion of the Transferred or
Licensed Technology which arise out of the operation of the business related to
CORTS or the CORTS System prior to April 16, 2004 other than any claim advanced
by PointSource, LLC, its Affiliates or successors and assigns.

10.2. Obligation of JMAR to Indemnify. JMAR agrees to indemnify, defend and hold
harmless Quist and Drake, their partners, representatives, agents, Affiliates
and their respective successors and assigns (the “Quist and Drake Indemnified
Parties”) from and against all Losses which any of them shall incur or suffer
based upon, arising out of or otherwise in respect of or involving (a) any
inaccuracy in or breach of any representation, warranty, covenant or agreement
of JMAR contained in the Transaction Documents which was not waived by Quist and
Drake prior to Closing, or (b) any liability, obligation, debt or commitment
included in the Assumed Liabilities, or (c) any third party claim or claims made
or threatened against Quist and Drake which arise out of or involve the
operation of the business related to CORTS or the CORTS System after April 16,
2004.

10.3. Notice and Opportunity to Defend.

(a) Notice of Asserted Liability. Promptly after receipt by any party hereto
(the “Indemnitee”) of notice of any demand, claim or circumstances that would
give rise to a claim or the commencement (or threatened commencement) of any
action, proceeding or investigation (an “Asserted Liability”) that may result in
a claim for indemnification under Section 10.1 or 10.2, the Indemnitee shall
give notice thereof (the “Claims Notice”) to the party obligated to provide
indemnification pursuant to Section 10.1 or 10.2 (the “Indemnifying Party”). The
Claims Notice shall describe the Asserted Liability in reasonable detail, and
shall indicate the amount (estimated, if necessary) of the loss or damage that
has been or may be suffered by the Indemnitee.

(b) Opportunity to Defend. The Indemnifying Party may elect to compromise or
defend, at its own expense and by its own counsel, any Asserted Liability. If
the Indemnifying Party elects to compromise or defend such Asserted Liability,
it shall within 30 days of receipt of the Claims Notice notify the Indemnitee of
its intent to do so, and the Indemnitee shall cooperate in the compromise of, or
defense against, such Asserted Liability. The Indemnifying Party shall reimburse
the Indemnitee for all out-of-pocket costs incurred by the Indemnitee in
connection with such cooperation. If the Indemnifying Party elects not to
compromise or defend the Asserted Liability, fails to notify the Indemnitee of
its election as herein provided or contests its obligation to indemnify under
this Agreement, the Indemnitee may pay, compromise or defend such Asserted
Liability. Notwithstanding the foregoing, neither the Indemnifying Party nor the
Indemnitee may settle or compromise any claim over the objection of the other,
provided, however, that consent to settlement or compromise shall not be
unreasonably withheld. In any event, the Indemnitee and the Indemnifying Party
may participate, at their own expense, in the defense of such Asserted
Liability. If the Indemnifying Party chooses to defend any claim, the Indemnitee
shall make available to the Indemnifying Party any books, records or other
documents within its control that are necessary or appropriate for such defense,
subject to reasonable confidentiality protections.

10.4. Limitation of Liability. Quist and Drake’s liability for indemnification
under Section 10.1 hereof shall be limited to an offset by JMAR against the
CORTS Payments.

11. Miscellaneous Provisions.

11.1. Waiver and Amendment. Any term or provision of this Agreement may be
waived at any time by the party which is entitled to the benefits thereof, but
only in a writing signed by such party, and this Agreement may be amended or
supplemented at any time, but only by written agreement of Quist and Drake and
JMAR. Any such waiver with respect to a failure to observe any such provision
shall not operate as a waiver of any subsequent failure to observe such
provision unless otherwise expressly provided in such waiver.

counterparts, each of which independently shall have the same effect as if it
were the original and all of which taken together shall constitute one and the
same document. Executed signature pages which are transmitted by facsimile to

Dispute arising out of or relating to this Agreement through informal
negotiation between appropriate representatives from each party. Within five
(5) 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 five (5) days from the 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 requesting mediation as set forth in
Section 11.10(d), below.

c. Information Requests. During the course of negotiations under Section 11.10,
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 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.

d. Mediation. In the event that any Dispute is not settled by the Parties within
five (5) days after the first meeting of the negotiating senior executives, a
Party may demand mediation and 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 ten (10) days after
the demand for mediation. Except as provided below in Section 11.10(e), 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.

e. The Parties by mutual written agreement may extend any of the time periods
set forth in Section 11.10(a) through (d).

f. Legal Proceedings. In the event that any Dispute is not settled by the
Parties through mediation as outlined in Section 11.10, either Party may
institute legal proceedings for that Dispute in a court of competent
jurisdiction.

11.11. Attorneys Fees and Expenses of Litigation. In the event suit is commenced
to enforce or contest this Agreement, or any portion thereof, the prevailing
party in such suit shall be entitled to recover from the non-prevailing party
all fees, costs and expenses of enforcing any right of such prevailing party
under and with respect to this Agreement, including without limitation, such
reasonable fees and expenses of attorneys and accountants, which shall include,
without limitation, all fees, costs and expenses of appeals.

11.12. Force Majeure. Whenever a period of time is prescribed for action by a
party hereunder, such party shall not be responsible for, and there will be
excluded from the computation for such period of time, any delays due to an
event of force majeure, including but not limited to strikes, riots, acts of
God, war, governmental laws, regulations or restrictions of general application
to the public at large, or any other causes beyond the control of such party.
