I. RECITALS
--------
WHEREAS, as the result of the discovery of contaminated groundwater in
the Main San Gabriel Valley Groundwater Basin (the "Basin"), a critical source
of drinking water for San Gabriel Valley residents, the United States
Environmental Protection Agency (EPA) placed four areas of the Basin on the
National Priorities List; and
WHEREAS, Suburban owns and operates drinking water extraction wells in
the Basin; and
WHEREAS, Suburban asserts that it has incurred costs and suffered
damages as a result of the groundwater contamination in the Basin; and
WHEREAS, Suburban has identified Aerojet and others as parties who may
have caused or contributed to the groundwater contamination in the Basin; and
WHEREAS, Suburban and Aerojet wish to enter into a tolling and
standstill agreement with respect to any claims the Parties may have arising
from the groundwater contamination existing in the Basin;
THEREFORE, the Parties, for good and sufficient consideration hereto
acknowledged, agree as follows:
II. TOLLING AGREEMENT
-----------------
In accordance with this agreement Aerojet hereby agrees to toll the
running of any statutes of limitation and any other statute, law, rule of
principle of equity with

similar effect (collectively "Statutes of Limitation") with respect to any and
all rights, claims, causes of action, counterclaims, third party claims, cross
claims and defenses Suburban may have or wish to assert against Aerojet which
are alleged to have occurred as the result of a release or releases of
substances, including the perchlorate ion and NDMA, which originated in any part
from property in the Basin which Aerojet has currently or formerly used or owned
that have impacted or threaten to impact Suburban's right and ability to extract
groundwater from the Basin (the "Claims"). With respect to contaminants other
than the perchlorate ion or NDMA, Aerojet is tolling the running of the Statute
of Limitations only with respect to its several share of alleged claims or
damage in proportion of its percentage contribution to said claims or damage, as
shown by the evidence. This Agreement shall commence on June 20, 2000, and
continue until such time as this Agreement is terminated pursuant to paragraph
VI of this Agreement (the "Tolling Period"). Aerojet agrees that the Tolling
Period shall be excluded from all computations of any limitations period
applicable to the Claims. Aerojet agrees that it shall waive and shall not
plead, assert, or otherwise raise any Statute of Limitation or any other time
related defense otherwise applicable to the Claims, to the extent such
limitations period or other time related defense is tolled by this Agreement, as
a bar to or other limitation on any Claim.
III. NO WAIVER
---------
The Parties, and each of them, do not waive and expressly reserve any
and all rights, claims, causes of action, counterclaims, cross claims, third-
party claims, and/or defenses, including but not limited to, any statute of
limitation, except as to the Tolling Period. This Agreement has no effect on any
and all rights, claims, causes of action, counterclaims, cross claims, third
party claims, or defenses already barred, tolled, or otherwise extinguished as
of June 20, 2000.
