agreement with DISTRIBUTOR substantially in the form of this Agreement, which
purports to give the subdistributor no greater rights than DISTRIBUTOR has under
this Agreement, and which provides that such agreement terminates automatically
upon the termination this Agreement, for any reason. DISTRIBUTOR shall at all
times remain liable for the performance of any approved subdistributor.

         2.3 No Other Distributor. Except as otherwise specifically provided
below or in Schedule 1, and notwithstanding the reference to a "non-exclusive"
distributor in Section 2.1, SpectraSCIENCE shall not appoint any other
distributor for the Products in the Territory during the term of this Agreement,
provided DISTRIBUTOR meets or exceeds its performance quotas pursuant to Section
3.3 and (if applicable) Schedule 1.

SECTION 3. DISTRIBUTOR'S OBLIGATIONS

         3.1 Best Efforts. DISTRIBUTOR shall use its best efforts to promote,
market, and distribute the Products in the Territory. DISTRIBUTOR shall conduct
its business in a professional manner that will reflect positively upon
SpectraSCIENCE and the Products.

         3.2 Product Promotion. DISTRIBUTOR shall exhibit and demonstrate the
Products at such trade shows in the Territory as DISTRIBUTOR determines in good
faith are necessary or useful in marketing and promoting the Products.
DISTRIBUTOR shall give SpectraSCIENCE reasonable prior notice of all such trade
shows such that SpectraSCIENCE can attend if it so desires. DISTRIBUTOR shall
otherwise meet all reasonable business standards for displaying, demonstrating,
and explaining the operation and use of the Products to customers and potential
customers.

         3.3 Performance Quotas.

                  3.3.1 DISTRIBUTOR acknowledges that low volume distribution of
the Products will adversely affect SpectraSCIENCE's goodwill in the Territory.
If SpectraSCIENCE terminates DISTRIBUTOR pursuant to Section 14 because
DISTRIBUTOR failed to meet any such quotas, DISTRIBUTOR specifically
acknowledges that pursuant to Section 14, it is not entitled to any
compensation, because, among other things, the damage to SpectraSCIENCE's
goodwill is likely to be at least as great as the losses DISTRIBUTOR might incur
as a result of any such termination.

                  3.3.2 DISTRIBUTOR agrees to purchase and take delivery of the
minimum purchase requirements of Products set forth in Schedule 1 hereof during
each quarter during the Term (as defined herein), commencing in the first
quarter of the second year of the Term. For purposes of determining compliance
with the minimum purchase requirements, DISTRIBUTOR's purchases hereunder shall
not be aggregated. Accordingly, DISTRIBUTOR may not apply purchases made during
any quarter to the minimum purchase requirement applicable to the following
quarter. If DISTRIBUTOR fails to meet such requirements, SpectraSCIENCE shall
have the right to appoint other distributors of the Product(s) in the Territory
or, at SpectraSCIENCE's option, to terminate this Agreement pursuant to Section
14.

         3.4 Submission of Purchase Orders.

                  3.4.1 DISTRIBUTOR shall deliver purchase orders to
SpectraSCIENCE for the Products not less than fourteen (14) days prior to the

additional or conflicting terms or conditions set forth in any purchase order
shall be of no force or effect.

                  3.4.2 Contemporaneously with the execution of this Agreement,
DISTRIBUTOR shall execute the initial purchase attached hereto as Exhibit A (the
"Initial Purchase Order"). The Products set forth in such purchase order shall
count against DISTRIBUTOR's minimum purchase requirements hereunder.
Notwithstanding anything to the contrary in this Agreement, the purchase price
for the Products set forth in the initial purchase order shall be due and

to delivery such Products until receipt of such payment.

purchase of any of the Products.

                  3.5.2 DISTRIBUTOR shall respond to and handle all customer
inquiries and complaints relating to the Products. DISTRIBUTOR's
responsibilities shall include, but not be limited to, all support, training,
use, and maintenance issues relating to the Products. DISTRIBUTOR shall perform
such responsibilities at its own expense, provided, however, that SpectraSCIENCE
shall use its commercially reasonable efforts to repair or replace any defective
Product to the extent of its warranty obligations hereunder. DISTRIBUTOR shall
promptly report to SpectraSCIENCE all suspected Product defects, errors,
technical difficulties, or other problems relating to the use or operation of
the Products (collectively, "Problems") and shall keep SpectraSCIENCE reasonably
informed of customer complaints concerning same. Without limiting the foregoing,
upon becoming aware of any Problem, DISTRIBUTOR shall report the Problem to
SpectraSCIENCE in writing in accordance with the following: (i) if the Problem
involves patient injuries, within twenty-four (24) hours; and (ii) for any other
Problem, within forty-eight (48) hours.

         3.6 Place of Business and Staffing. DISTRIBUTOR shall provide and

quarterly report shall also include such further information on marketing
contacts, training status of support personnel and identification thereof, and
any such other information, including certified financial statements, as
SpectraSCIENCE may reasonably require.

         3.8 Advertising, Etc. DISTRIBUTOR shall provide SpectraSCIENCE with
copies of all advertising, brochures, and other materials relating to the

that nothing herein shall preclude DISTRIBUTOR from selling the Products to any
customer, wherever located, who purchase Products with the intent expressed in
writing to use the Products in the Territory.

         3.10 No Modifications or Translations of Products. DISTRIBUTOR shall
not modify or alter the Products, or combine the Products with other products,

written consent.

         3.11 No Reverse Engineering. DISTRIBUTOR shall not attempt to decompile
or reverse engineer any of the Products or part thereof.

         3.12 Pricing. The parties acknowledge that DISTRIBUTOR is free to
determine the prices at which it will market the Products. DISTRIBUTOR
recognizes and agrees with SpectraSCIENCE's objective of being a
price/performance leader, however, so DISTRIBUTOR shall use its best efforts to
sell Products at prices not substantially above SpectraSCIENCE's suggested
international retail prices.

         3.13 Insurance. DISTRIBUTOR shall maintain in force, during the term of
this Agreement and for as long as a practical need exists, one or more policies
of liability insurance, including without limitation product liability
insurance, with an insurer reasonably acceptable to SpectraSCIENCE that shall

Products and in an amount reasonably determined by SpectraSCIENCE.
SpectraSCIENCE shall be designated as an additional insured under such policy
and shall be provided with a certificate of insurance within thirty (30) days
after the issuance and each renewal thereof.

the United States or the Territory shall request or order any corrective action
with respect to Products supplied hereunder, including without limitation any
Product recall, customer notice, restriction, change, correction active, or any
Product change, the parties shall cooperate fully to effectuate such corrective
action. The foregoing shall be without limitation to SpectraSCIENCE's right

fees and disbursements of counsel, consultants, and expert witnesses

DISTRIBUTOR's or any of its subdistributor's breach of this Agreement,
negligence, willful misconduct, or violation of any applicable law, rule,
regulation, or order, (ii) any act or omission by DISTRIBUTOR or any of its
subdistributors, or (iii) any unfair business practice of DISTRIBUTOR or any of
its subdistributors. SpectraSCIENCE will (i) promptly notify DISTRIBUTOR in
writing of any notice of claim or of any threatened or actual suit, and (ii) at
DISTRIBUTOR's expense, give DISTRIBUTOR all reasonable non-monetary assistance

failing which the Products shall be deemed accepted by DISTRIBUTOR. DISTRIBUTOR
shall promptly furnish to such written evidence or other documentation of the
shortage, damage, or discrepancy, as SpectraSCIENCE may deem appropriate. If
such evidence and documentation demonstrates to SpectraSCIENCE's reasonable
satisfaction that SpectraSCIENCE is responsible for the shortage, damage, or
discrepancy, SpectraSCIENCE shall promptly deliver additional or substitute
Products to DISTRIBUTOR, but in no event shall SpectraSCIENCE be liable for any
additional costs, expenses, or Damages, suffered or incurred by DISTRIBUTOR as a
result of such shortage, damage, or discrepancy. DISTRIBUTOR shall return or
