Lessor is the owner of the land described on the attached Exhibit "A"
(cross-hatched portion) consisting of approximately 21 acres, together with any
appurtenances, and is referred to in this lease as "the Premises." Lessee wishes
to construct a building on the Premises for use as an algae processing and
storage facility.

The parties therefore agree as follows:

SECTION 1. AGREEMENT TO LEASE

Lessor hereby leases to Lessee and Lessee hereby leases from Lessor the Premises
on the terms and conditions set forth below.

SECTION 2. TERM

TERM. The term of this lease shall begin on November 29, 1995. The term shall
continue for 25 years from that date to midnight on November 28, 2020. Lessee
shall be entitled to renew this Lease for an additional term of 25 years at the
rent in effect at the end of the original term. All terms of this lease shall
remain in effect in the renewal term, including the escalation in rent set forth
below.

SECTION 3. RENT; SECURITY

<PAGE>

3.1 BASIC RENT. Basic rent shall be the sum of $12,000.00 per year. Lessee shall
pay basic rent annually in advance on the anniversary of the commencement of
this lease each year. It is understood that rent for the first year is paid upon
execution of this agreement.

3.2 GENERAL RENT PROVISIONS. All rents shall be payable without deduction or
offset to the order of Lessor at the address shown in paragraph 14.2 or at such
other address as may be designated from time to time by Lessor. It is the
intention of the parties that all rents payable under this lease shall be net to
Lessor and that all costs, expenses and obligations during the lease term
relating to the premises shall be paid by Lessee.

3.3 ESCALATION. On November 29, 1996, and on the 29th day of November of each
succeeding year, there shall be computed any increase in the cost of living
based on the "Consumer Price Index -All cities and U.S. Average" (1967-100)
hereinafter called the "Index", published by the Bureau of Labor statistics of
the U. S. Department of Labor. The Index number entitled "All Items" for the
month of January, 1996, shall be the base Index number for purposes of
computation. The monthly basic rent set forth in Sub-paragraph (a) hereof shall,
in the event of an increase in the cost of living determined as above-mentioned,
be increased effective the 29th day of November of each succeeding calendar year
during the term of this Lease Agreement wherein there is an increase in said
cost of living. The current Index number shall be divided by the base Index
number and the result multiplied by the basic monthly rental mentioned above
shall be the adjusted monthly rental. Lessor shall, within a reasonable time
after determining the appropriate information, with respect to said increase,
give Lessee notice of such increase, and Lessor's computation thereof shall be
binding and conclusive unless Lessee shall, within fifteen (15) days after the
giving of said notice, advise Lessor of any dispute in conjunction therewith.
Any dispute between the parties as to such computation shall be determined by a
Board of Arbitration with one member selected by Lessor and one member selected
by Lessee and one member selected by the selectees of Lessor and Lessee. If
publication of the Consumer Price Index shall be discontinued, the parties shall
thereafter accept com- parable statistics on the cost of living for the city of
Portland as they shall be computed and published by any government agency or by
a responsible financial periodical of recognized authority. In the event that
any method is not utilizable and does not have an appropriate Index for the
given month that is herein involved, computation shall be undertaken in the form
of interpolation between given dates that are applicable so that the spirit and
intent of this paragraph can be given effect.

SECTION 4. USE OF PREMISES. Lessee shall use and permit the use of the premises
only for the construction, maintenance, and operation of an algae processing and
storage facility, as well as any agricultural use and wetlands preservation.

to the taxing authority. If any such tax, assessment or charge may be

                                       83

after the lease term.

any tax, assessment or charge in accordance with the procedures established by

subjected to a11y lien as a result of the contest. Lessee may prosecute such
contest in the name of Lessor as Lessor's attorney in fact. All tax contests

authority on account of any tax or assessment which was originally paid by
Lessee shall be the sole property of the Lessee.
