         ANTICIPATED OR LOST PROFITS, INCIDENTAL DAMAGES OR LOSS OF TIME OR

                  7.2.1 MATERIAL, QUALITY AND SPECIFICATIONS. Subject to the
         provisions of SECTIONS 7.5 and 10.5, Emcore warrants to Hakuto and to

         the end user customer or as mutually agreed by Emcore and Hakuto from
         time to time hereafter.

                  7.2.2 EXCLUSIONS AND DISCLAIMER. THE EXPRESS WARRANTY GRANTED
         ABOVE SHALL EXTEND DIRECTLY TO AUTHORIZED DISTRIBUTORS AND, EXCEPT AS
         PROVIDED IN SECTIONS 7.5 AND 10.5, IS IN LIEU OF ALL OTHER WARRANTIES,
         WHETHER EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY
         AND FITNESS FOR PARTICULAR PURPOSE. Except as provided in SECTION 7.5
         and 10.5, Emcore will be liable under this warranty only for
         replacement of the defective Product or, at the option of Hakuto or the
         customer, credit of the Customer Price of the defective Product.

         7.3 SPARE PARTS CONSIGNMENT INVENTORY. Emcore shall be responsible for
supplying all Spare Parts necessary to satisfy Emcore's obligations under the
foregoing warranties, and Hakuto shall be responsible for supplying all
installation or service relating to the warranty program except as otherwise
provided in SECTIONS 7.1.1 and 7.1.2 with respect to specification
non-conformance. Emcore agrees to maintain with Hakuto, at such location in the
Territory as Hakuto may designate, a consignment inventory of Spare Parts
("Consignment Inventory") determined by Emcore to be reasonably necessary for
the prompt and efficient delivery of warranty service. Hakuto agrees to provide
to Emcore periodic reports setting forth: (1) with respect to all warranty
claims made during such month, the identity of the end user, the nature of the
claim, the service provided and the Spare Parts used, if any, in providing such
service; and (2) the current levels of all Spare Parts comprising the
Consignment Inventory.

         7.4 INSURANCE. Emcore shall maintain in force during the term of this
Agreement, and for a period of five (5) years thereafter, product liability
insurance based on an occurrence basis rather than a claims made basis, with
respect to the Products, in an amount not less than Two Million Dollars
($2,000,000) per person and Two Million Dollars ($2,000,000) per occurrence.
Such insurance policies shall name Hakuto as an additional insured, or shall
contain coverage protecting Hakuto as a vendor of the Products. Emcore shall
furnish Hakuto with properly executed Certificates of Insurance. Such insurance
policies shall include the obligation of the

insurer to notify Hakuto, not less than thirty (30) days in advance, of any
reduction, non-renewal or cancellation of the foregoing insurance. In the event
that Emcore fails to purchase or maintain in force the above insurance, Hakuto
may purchase such insurance on Emcore's account, and at Emcore's expense, and
nothing herein shall waive Emcore's obligation to purchase and maintain such
insurance.

         7.5 INDEMNIFICATION. Emcore shall indemnify and, at its own expense and
with diligence, defend and hold Hakuto, its subsidiaries and affiliates, and
their respective customers, free and harmless from and against any and all
claims, losses, damages, suits, causes of action, obligations and/or liabilities
(and against all associated costs and expenses, including, without limitation,
reasonable attorneys' fees and costs of litigation) whenever and wherever they
may occur, arising directly or indirectly from the sale or use of the Products,
provided, however, Emcore's obligation to indemnify Hakuto under this paragraph
shall not extend to any claims, losses, damages, suits, causes of action,
obligations and/or liabilities arising out of the gross negligence or
intentional wrongful conduct of the claimant.

8.       OBLIGATIONS OF HAKUTO.

("Contract Year"). Hakuto will submit to Emcore purchase orders during each of
the [*]. For each succeeding Contract Year of the Agreement, Hakuto and Emcore
shall mutually agree on a minimum purchase order amount for each such year prior
to commencement of such Contract Year. In computing the value of the minimum
purchase amount for each Contract Year, there shall be included the value of all
Equipment shipped during said Contract Year, the value of orders placed by
Hakuto though not shipped by Emcore during the Contract Year, and the value of
orders procured by Hakuto but canceled by Hakuto's customer by reason of
Emcore's inability to perfect delivery of the Equipment within six (6) months
from date of the order. The value of all of the foregoing orders which exceeds
the minimum purchase commitment for any Contract Year shall be credited to
Hakuto's minimum purchase order commitment for the subsequent Contract Year.

this Agreement and each twelve (12) month period thereafter during the term of
this Agreement or any renewal term thereafter.

10. TRADEMARK AND PATENT RIGHTS.

         10.1 LICENSE GRANT. Exhibit C attached hereto and made a part hereof
identifies all registered, recorded or issued material intellectual property,
including registered copyrights and trademarks, issued patents and applications
for any of the foregoing, which have been, or, with respect to applications, may

together with other intellectual property in which Emcore claims a proprietary
interest in

the Territory such as, inter alia, know-how and common law trademarks shall
hereafter be referred to as "Intellectual Property"). Hakuto is hereby granted a
license and privilege to use all of the Intellectual Property, including any
improvements, modifications or functional equivalents, during the term of this
Agreement in furtherance of the objectives of this Agreement. Hakuto shall not
have the right to sublicense (except to Hakuto's subsidiaries and affiliates)
the Intellectual Property or otherwise permit its use by third parties without
Emcore's prior written consent. If Hakuto is required by law to register its
licenses in Japan or, in its sole discretion, determines that registration
hereof should be effected in order to protect the rights and interests of Hakuto
hereunder, then Emcore shall cooperate with Hakuto to effect the same.

         10.2 HAKUTO COOPERATION. Hakuto shall advise Emcore from time to time
of any additional filings, registrations or other actions that may be necessary
or desirable for the protection of Emcore's Intellectual Property in the
Territory. Upon Emcore's request, Hakuto shall assist Emcore in connection with
the issuance or registration of any new Emcore patents, copyrights, trademarks
or other Intellectual Property in the Territory.

         10.3 INFRINGEMENT. Hakuto shall at all times respect and protect
Emcore's rights of total ownership of the Intellectual Property in the
Territory. Hakuto shall promptly notify Emcore of any infringements of such
rights of which Hakuto has notice and shall assist Emcore in taking such action
against such infringement as Emcore may elect.

         10.4 TERMINATION OF LICENSE. Upon termination of this Agreement for any
reason, Hakuto shall promptly relinquish to Emcore any rights to the use of the
Intellectual Property and shall thereafter refrain from using the same.

         10.5 INFRINGEMENT INDEMNIFICATION. If Hakuto or its customers are
served notice of alleged infringement of any patents, designs, copyrights and/or
trademarks arising from the sale or use of any of the Products, Emcore shall, at
its own expense and with diligence, defend and hold Hakuto and its customers
free and harmless from and against any and all claims, loss, damage, suits,
causes of action and/or liability (and against all associated costs and
expenses, including, without limitation, reasonable attorneys' fees and costs of
litigation) whenever and wherever they

may occur, on account of said alleged infringement; provided, however, that
Emcore shall have no obligation to indemnify Hakuto or its customers to the
extent the alleged infringement is due solely to: (a) a Product modification by
Hakuto or the customer; (b) use of a Product in combination with any other
device or thing; or (c) failure to use the Product in accordance with its
customary use or in conformity with Emcore's instructions and operating
guidelines. If Emcore shall fail or refuse to do so, Hakuto and its customers
may take such action as Hakuto or its customer, or jointly, may deem necessary,
and all costs, attorneys' fees, losses or damages as may be incurred by Hakuto
or its customers shall be the obligation of Emcore to be recovered by Hakuto or
its customers by suit or otherwise.

         10.6 QUALITY CONTROL. In connection with any use hereunder by Hakuto of
any registered or unregistered trademark owned by Emcore, Emcore shall have the
right at all times to: (a) establish and require Hakuto's adherence to quality
control standards governing the repair, sale and quality of the Products; and
(b) establish and require Hakuto's adherence to standards governing the manner
of display of any Emcore trademark in promotional, technical and informational
materials. Emcore shall have the right to request, at reasonable intervals,
inspection by Emcore or its designee of Hakuto's operations and of any materials
used or created by Hakuto displaying any Emcore trademark, so that Emcore can
verify to its satisfaction that the Products, services and display of trademarks
conform to the appropriate standard of quality.

11. CONFIDENTIALITY. Each party hereto when receiving information from the other
party (in such case, a "Receiving Party") agrees to use its best efforts to hold
in strict confidence and not to disclose to others or use, for a period of three
years after termination hereof, any technical or business information,
manufacturing technique, process, experimental work, trade secret or other
confidential matter relating to the business of the party in possession of such
information (such party, a "Disclosing Party") or relating to the Products, in
the case of Hakuto, or the other party's business ("Confidential Information"),
except to the extent necessary to further the objectives of this Agreement. This
SECTION 11 shall not apply to: (1) information known to the Receiving Party
prior to disclosure by the Disclosing Party of Confidential Information; (2)
Confidential Information which is, or becomes through no fault of the Receiving
Party, generally known or available to the public; (3) Confidential Information
which is received by the Receiving Party from

Information which the Disclosing Party discloses to a third party who is not
bound by confidentiality obligations, unless such third party is a subsidiary or
affiliate of the Disclosing Party; and (5) information independently developed
by the Receiving Party. The Receiving Party shall, upon request (and upon
termination of this Agreement without request), deliver to the Receiving Party
any and all drawings, notes, documents and materials received from the Receiving
Party.

12. ASSIGNMENT. Neither party shall assign, transfer or otherwise dispose of
this Agreement or any of its rights or obligations hereunder in whole or in part
to any individual, firm or corporation without the prior written consent of the
other party, and any attempted assignment in violation of this provision shall
be null and void.

13.      TERM AND TERMINATION.

         13.1 TERM. This Agreement shall take effect on the effective date set
forth on the first page hereof and shall remain in effect for a period of ten
(10) years thereafter unless earlier terminated in accordance with the terms
hereof. This Agreement may be terminated by either Party upon the expiration of
the ten (10) year period by giving six (6) months' prior written notice to the
other party of its intent not to extend the Agreement for further periods.
Unless such notice of intent to terminate is given, this Agreement shall
continue to remain in effect after the initial ten (10) year period for further
consecutive periods of one (1) year each, subject, however, to the right of
either party to terminate the Agreement during each such extended one-year
period by giving six (6) months' prior written notice to the other party of its
intent to terminate.
