SUBJECT:LETTER AGREEMENT/LEASE AMENDMENT 1 WITH RESPECT TO EXTENSION OF LEASE
TERM AND ESTABLISHMENT OF NEW BASE RENT FOR UNITS #4 AND #5 AND ESTABLISHMENT OF
NEW COMMENCEMENT DATE FOR UNIT #7 OF THE PORT HUENEME AQUACUL TUIRE CENTER

 

Gentlemen:

 

In accordance with Paragraph 58 of the Addendum to that certain Sublease, dated
October 2, 2000, by and between Stellar Biotechnologies, Inc. ("Stellar'') and
the Port Hueneme Surplus Property Authority ("SPA") for Units #3, #4, and

#5 , Stellar has notified the SPA of its desire to exercise its option with
respect to Units #4 and #5 for five-years and the SPA has accepted pursuant to
SPA Resolution No. 30 (attached). Stellar's Sublease of Unit #3 terminated of
its own accord on October 2, 2005 .

 

Paragraph 58 of the Sublease Addendum obliges the Parties to agree with respect
to the current Market Rental Rate for option periods, which on the basis of all
recent leasing activity at the Port Hueneme Aquaculture Center is currently

$0.15 per square foot of land per month with subsequent annual cost of living
("CPI") increases for years 4 through 5.

 

Accordingly, Paragraph 60 of the Addendum is hereby amended and replaced by the
following revision:

 

60. Establishment of Base Rent During the First Five-Year Option Period.
Commencing October 1, 2005 and continuing through September 30, 2006 , Lessee's
Base Rent shall be increased to $4,454.85/month for Units #4 and #5. This rental
rate takes into account the previously agreed to concept that 1,000 square feet
of Unit #4 is associated with the pump house, and Stellar is not required to pay
rent on that common area. On October 1, 2006 the Base Rent shall be adjusted
(but not reduced) for increases, if any, in the CPI index (for Ventura County,
if available; otherwise for the Los Angeles/Long Beach metropolitan area), which
occurred during the preceding twelve (12) month period. A similar adjustment
shall be made on each October 1st thereafter for the remaining term of the
option period ending in 2010.

With respect to Unit #7, the "Commencement Date" set forth in Paragraph 60 of
the Addendum to that certain additional Sublease, dated August 1, 2005, by and
between Stellar and the SPA is hereby changed from August 1, 2005 to October 1,
2005 to reflect the delay in occupancy by Stellar due to required tenant
improvement work.

 

All other terms, conditions and provisions of both Subleases shall remain in
full force and effect.

 

Please indicate Stellar's concurrence with these Sublease Amendments by
executing and dating this letter below and returning same to this office.

 

 

 

Sincerely,

 

/s/ Robert Hunt

 

Robert L. Hunt SPA Manager

 

  

The foregoing Amendments to the two Subleases as described above are agreed to
this 31st day of October, 2005.
