Exhibit 10.5

GROUND LEASE

          This
Ground Lease (this “Lease”) is dated for reference
purposes as of November 30,
2005, and is executed on the dates set forth with the signatures below by and between
AEROJET-GENERAL CORPORATION, an Ohio corporation (“Lessor”), and AMPAC FINE CHEMICALS LLC, a
California limited liability company (“Lessee”).

RECITALS

          A. Lessor owns approximately eight thousand five hundred (8,500) acres of land located south
of State Highway 50 and east of Sunrise Boulevard and bordering the southern edge of Folsom
Boulevard and the northern edge of White Rock Road, in Sacramento County, California, including the
buildings and other improvements thereon (collectively, the “Aerojet Site”). The Aerojet Site
serves as Lessor’s business headquarters, and some of the Aerojet Site is used for the development
and production of various products, including, but not limited to, explosives and propellants
(collectively, the “Aerojet Site Adjoining Uses”). Some of the Aerojet Site Adjoining Uses, as
well as some of the Reserved Uses (defined below), require compliance with Quantity/Distance
Restrictions (defined below).

          B. Among the improvements located on the Aerojet Site are private roadways (collectively, the
“Roadways”) by which Lessor and Lessor’s invitees, licensees, grantees, tenants, employees, agents,
and representatives enjoy ingress and egress to, from, and among all portions of the Aerojet Site.
As of the Term Commencement Date (defined below), Lessor owns, maintains, and controls all of the
Roadways.

          C. Lessor’s ownership and use of most of the Aerojet Site are subject to the Partial Consent
Decree (defined below) and may, in the future, become subject to other or different decrees or
administrative orders or demands issued by, at the request or with the consent of the PCD Agencies
(defined below), or by any court of competent jurisdiction (collectively, including any
modifications and supplements thereto issued from time to time, the “Governmental Decrees and
Orders”).

          D. The Partial Consent Decree currently imposes use restrictions and other requirements upon
most of the Aerojet Site, and such restrictions and requirements may, in the future, become
changed, supplemented, extended, or terminated, in whole or in part, pursuant to amendments to the
Partial Consent Decree, other Governmental Decrees and Orders, or the Risk Assessment (defined
below) (collectively, as effective and amended from time to time, the “Governmental Restrictions”).

          E. The scope of the Partial Consent Decree includes a remedial investigation/feasibility study
and may include a risk assessment (a “Risk Assessment”). The Partial Consent Decree does not
establish the extent of remedial action that may be required. Remedial design/remedial action
(“RD/RA”) activities are anticipated to be governed by either an amendment to the Partial Consent
Decree or other Governmental Decrees and Orders. The nature and extent of any RD/RA activities
that may be required and the Governmental

1

 

Restrictions resulting from, or related to, such activities are not and cannot be known as of
the execution and delivery of this Lease.

          F. Lessee desires to lease and use a certain portion of the Aerojet Site, which portion is
hereinafter defined as the “Demised Land.” Lessor desires to demise the Demised Land to Lessee and
to provide to Lessee access to the Demised Land and to the AFC Buildings (defined below) across
certain of the Roadways. Some of Lessee’s uses of the Demised Land and the AFC Buildings will
require compliance with Air Emissions Requirements (defined below).

          G. Prior to, or concurrently with, the execution and delivery of this Lease, Lessor conveyed,
or is conveying, to Lessee fee title to the AFC Buildings. Lessor has not conveyed, and in no
event shall Lessor convey as part of this transaction, to Lessee fee title to any of the Roadways,
the Demised Land, the Aerojet Buildings (defined below), or other Improvements (defined below)
located within the Demised Land except the AFC Buildings.

          H. In addition to the Aerojet Site Adjoining Uses, Lessor or its successor or successors in
title will be obtaining land use entitlements for, subdividing, and constructing improvements upon
various portions of the Aerojet Site that are adjacent to, or near, the Demised Land (collectively,
“Adjacent Development”). Adjacent Development will be a mixed-use development, including
single-family and multiple-family housing, schools, day-care centers, parks, retail stores,
offices, and other types of uses.

          I. The purpose of this Lease is to set forth all of the terms and conditions under which
Lessor leases to Lessee, and Lessee leases from Lessor, the Demised Land for Lessee’s use as
permitted under this Lease, as well as to set forth all of the terms and conditions under which
Lessee’s Access Rights (defined below) are provided by Lessor to Lessee and Lessor’s Reserved
Rights are retained by Lessor, all subject and subordinate to the Governmental Restrictions. In
addition, this Lease sets forth commitments by Lessor and Lessee to facilitate their compliance
with the Quantity/Distance Restrictions and the Air Emissions Requirements, respectively, and to
accommodate Adjacent Development.

          NOW, THEREFORE, and in reference to the foregoing recitals (collectively, the “Recitals”),
Lessor and Lessee, in consideration of the various obligations set forth in this Lease, agree as

9

 

procedures for all or some persons entering upon the Aerojet Site or through the

basis;

                  (iii) To close or restrict temporarily use of the Lessor Controlled Roadways or any

instruments and documents;

                  (vi) To grant easements over, and licenses to use, the Lessor Controlled Roadways or
any portion thereof to third parties chosen by Lessor; provided the same do not unreasonably
interfere in any material way with Lessee’s exercise of Lessee’s Access Rights;

                  (vii) To conduct, or contract for, all maintenance, repair, and improvement work on the
Lessor Controlled Roadways as Lessor, in its sole and absolute discretion, without detriment
to Lessee’s Access Rights, may determine is appropriate or necessary from time to time; and

                  (viii) With respect to any portion of the Lessor Controlled Roadways over which Lessee
exercises Lessee’s Access Rights, Lessee agrees that, when, if ever, that portion, or some
other area as a substitute or alternative for that portion, which is available at all times
industrial, becomes a public roadway, whether through acceptance of an offer of dedication
made by Lessor or otherwise, then Lessee’s Access Rights shall cease as to that portion or
other area, with Lessee relying upon the public nature of that portion or other area to
assure access to the Premises. When, if ever, and to the extent that, dedicated public
roadways over any portion of the Aerojet Site offer access to the Demised Land acceptable to
Lessee in Lessee’s reasonable discretion, Lessee’s Access Rights over Lessor Controlled
Roadways shall cease and no longer be a part of this Lease.

10

 

               (c) Lessee’s Access Rights shall, from time to time, at the request of either Lessor or

Roadways as reasonably designated by Lessor and approved by Lessee, which approval shall not be
unreasonably withheld or delayed and shall be granted whenever the chosen route is reasonably
convenient for Lessee’s purposes under this Lease. To evidence, in the Official Records, the exact
location for exercise of Lessee’s Access Rights, and to assure third parties that no other portion
of the Lessor Controlled Roadways is then encumbered by Lessee’s Access Rights, Lessor and Lessee
shall, from time to time, execute and record in the Official Records amendments to this Lease
setting forth in Exhibit “I” attached hereto the then-current location for exercise of Lessee’s
Access Rights.

          2.3 Roadway Costs and Expenses.

               (a) Lessor shall keep the Lessor Controlled Roadways used for Lessee’s Access Rights in as
good operating condition and repair as at the Term Commencement Date. Lessor shall pay all costs
and expenses for repair, maintenance, and improvement of the Lessor Controlled Roadways, and Lessee
shall have no obligation to contribute or reimburse Lessor for any portion thereof. Lessor’s
obligations under this Section 2.3(a) shall survive the Term if Lessee acquires fee title to the
Premises and such obligations shall be evidenced in the Access Easement Agreement.

               (b) Lessee shall pay all such costs and expenses for repair, maintenance, and improvement of
the Lessee Controlled Roadways, and Lessor shall have no obligation to contribute or reimburse
Lessee for any portion thereof.

          2.4 Term. The term of this Lease (the “Term”) shall commence on the Term Commencement
Date, and shall expire at the expiration of thirty years (30) from the Term Commencement Date (the
“Expiration Date”), subject to extension and/or earlier termination as provided elsewhere in this
Lease. Subject to the terms of this Section 2.4, Lessee shall have the option (the “Renewal
Option”) to extend the Term of this Lease for a period of thirty (30) years beyond the Expiration
Date (the “Renewal Term”). The Renewal Option shall be effective only if no Default by Lessee is
occurring under this Lease, either at the time of exercise of the Renewal Option or the time of
commencement of the applicable Renewal Term. The Renewal Option must be exercised, if at all, by
written notice (“Election Notice”) from Lessee to Lessor given not less than six (6) months prior
to the Expiration Date. An Election Notice given by Lessee to Lessor shall be irrevocable. If
Lessee fails to exercise the Renewal Option in a timely manner, as provided for above, the Renewal
Option shall thereafter be null, void and of no further force or effect. The Renewal Term shall be
upon the same terms and conditions as the initial Term. The Renewal Option is appurtenant to, and
shall not be assigned or transferred by Lessee separate from, a permitted assignment of all of
Lessee’s interests under this Lease. Any purported assignment of transfer of the Renewal Option to
any Person that is not concurrently receiving a permitted assignment of all of Lessee’s interests
under this Lease shall be null and void and a material breach of this Lease by Lessee.

          2.5 Purchase Option. Subject to the terms of this Section 2.5, Lessee shall have a
recurring option (the “Purchase Option”) to purchase Lessor’s fee simple interest in the

11

 

Demised Land and Lessor’s Improvements (including the Aerojet Buildings), together with
comparable easements, utility and service rights and obligations as then currently in place under
this Lease, at any time, in exchange for payment of a purchase price in the amount of One Thousand
Dollars ($1,000.00); provided, however, that Lessee shall not be entitled to exercise the Purchase
Option until such time (i) as the United States Environmental Protection Agency has delisted the
Demised Land as a Superfund site, (ii) Lessee shall have committed to pay to Seller (as defined in
the Purchase Agreement), at or prior to the closing of Lessee’s purchase of the Demised Land, the
full principal amount due to Seller under the Notes (as defined in the Purchase Agreement) and any
interest owed thereon, and under the Earn Out (as defined in the Purchase Agreement), and (iii)
Lessee shall have committed to pay to Seller, at or prior to the closing of Lessee’s purchase of
the Demised Land, any and all monies (including interest) due to Seller under the Earn Out (as
defined in the Purchase Agreement). The foregoing three (3) conditions are the only conditions to
Lessee’s exercise of the Purchase Option; provided, however, that the Purchase Option shall
terminate and be of no further force or effect if and when this Lease is terminated, regardless how
such termination is effected, and shall not be effective or binding upon Lessor after any such
termination of this Lease. The Purchase Option must be exercised, if at all, by written notice
(“Purchase Notice”) from Lessee to Lessor given not less than six (6) months, or more than twelve
(12) months, prior to the date Lessee desires to acquire Lessor’s fee interest. Any such Purchase
Notice given by Lessee to Lessor shall be irrevocable, which purchase notice shall not constitute
notice under Section 2.8(d). The deed transferring the property to Lessee shall include any
environmental and other use restrictions necessary as provided in Section 2.2 of Exhibit “G”. Upon
Lessee’s delivery of the Purchase Notice, the parties will execute a purchase agreement
substantially in the form of Exhibit “J” attached hereto and made a part hereof, which will
provide, among other matters the following:

               (a) At the closing of Lessee’s purchase of the Demised Land and Lessor’s Improvements,
Lessor’s grant will be made by grant deed subject only to (1) all matters now of record, (2) all
matters that a true, correct and complete survey or visible inspection of the Demised Land or
Premises would reveal as of the date of such closing, (3) all taxes, assessments and governmental
charges which are not delinquent, (4) all zoning, building, platting and similar restrictions, and
(5) and all matters caused by Lessee, its successors, sublessees and assigns, and Lessee will
accept the Premises in an “AS IS” and “WITH ALL FAULTS” condition;

               (b) After Lessee exercises the Purchase Option, Lessor will not create or permit through its
actions or inactions any additional encumbrances on the Premises without Lessee’s consent;

               (c) Neither Lessee nor Lessor will be responsible for any real estate or brokerage commissions
in connection with the sale of the property pursuant to the Purchase Option, and each of Lessor and
Lessee agree to indemnify and hold the other harmless in respect of any parties claiming any such
real estate or brokerage commissions arising by, through or under the respective indemnifying
party;

               (d) Closing shall occur as soon as practicable after six (6) months after Lessee’s written
notice of the exercise of the Purchase Option. All closing and escrow costs for such transaction
will be allocated as is customary practice in Sacramento County; and

12

 

               (e) Lessor and Lessee shall cooperate in all commercially reasonable respects, including
executing any additional documents reasonably required, to consummate the transaction as
contemplated by this Section 2.5 following Lessee’s exercise of the Purchase Option. Should the
parties be unable to agree upon aspects of such transaction, those aspects will be resolved
pursuant to the dispute resolution provisions of Section 15.16.

               (f) Following Lessee’s exercise of the Purchase Option, and prior to the closing of Lessee’s
purchase of the Demised Land, Lessor and Lessee shall execute and cause to be recorded in the
Official Records of Sacramento County, California, at Lessee’s sole cost, easement agreement(s),
that are appurtenant to and run with the land, to the extent the same may be necessary to
memorialize the then current rights and obligations of Lessor and Lessee, as contemplated by
Sections 2.2, 4.1(a), 4.1(b), 4.4 and Exhibit “C” (the “Easements”). The Easements shall be in
form and substance as may be necessary for First American Title Insurance Company, or a title
company reasonably acceptable to Lessee, to include the same as insured easement parcel(s) in the
legal description of the title insurance policy to be issued to Lessee at the closing of Lessee’s
purchase of the Demised Land and sufficient for such title company to issue a CLTA 103.4 or 103.7
endorsement (or its successor endorsement).

               (g) In the event the conditions for Lessee’s exercise of the Purchase Option as set forth
above are satisfied and Lessee gives a Purchase Notice, but Lessor asserts that it is unable to
transfer its fee simple interest in the Demised Land and Lessor’s Improvements to Lessee due to the
fact that any such transfer would violate Governmental Restrictions, then (1) Lessor shall use its
commercially reasonable efforts to satisfy whatever conditions are required to be satisfied under
such Governmental Restrictions in order to lawfully transfer fee simple interest in the Demised
Land and Lessor’s Improvements to Lessee, and (2) Lessee shall have the option to extend the term
of this Lease for an additional ninety-nine (99) years (or such shorter period to the extent
required by Law) or until such time as Lessor may lawfully transfer fee simple title to the Demised
Landlord and Lessor’s Improvements and such a transfer is consummated.

               2.6 Quiet Enjoyment. Provided that Lessee fully performs all the terms of this Lease
on Lessee’s part to be performed, including payment by Lessee of all Base Rent and Additional Rent,
Lessee shall peaceably and quietly have, hold and enjoy the Premises during the Term without
hindrance, disturbance or molestation from or by Lessor, or any other party claiming through
Lessor, subject to the Encumbrances.

               2.7 Termination. Lessee may terminate this Lease in its sole discretion without cause
at any time prior to the Expiration Date by giving Lessor no less than two (2) years’ prior written
notice of Lessee’s intention to terminate. Upon the date of termination so specified in Lessee’s
notice, this Lease and the estate hereby granted shall expire and terminate with the same force and
effect as if the date specified in such notice were the Expiration Date, and all rights and
obligations of Lessee and Lessor hereunder shall expire and terminate (except for such provisions
that expressly survive the termination or earlier expiration of this Lease).

13

 

               2.8 Aerojet Buildings.

               (a) Lessor represents that the list attached hereto as Exhibit “H” is a true and complete list
of the Aerojet Buildings, with a brief description of the status of such buildings.

               (b) Pursuant to the Purchase Agreement between Lessor, Aerojet Fine Chemicals LLC, and
American Pacific Corporation dated as of July 12, 2005 as amended (the “Purchase Agreement”),
Lessor shall retain ownership of the Aerojet Buildings on and after the Term Commencement Date, and
Lessee shall have no interest in them.

               (c) Lessee hereby agrees to provide to Lessor, at all times during the Term (or subsequent to
the Term if Lessee acquires fee title to the Premises), subject to the provisions of subpart (d) of
this Section 2.8 and subject to Force Majeure, reasonable and sufficient ingress within the
Premises for the Reserved Uses (“Lessor’s Access Rights”). Lessor’s Access Rights shall be deemed
to be an easement appurtenant to Lessee’s interests in the Demised Land and a covenant real,
running with the Demised Land. Lessee shall have no right to terminate or restrict Lessor’s Access
Rights during the Term (or subsequent to the Term if Lessee acquires fee title to the Premises),
subject to the following provisions:

               (i) Lessor’s Access Rights are non-exclusive;

               (ii) Subject to the terms and conditions of Lessor’s Access Rights as set forth in this Lease,
and subject to the rights, if any, to use Lessee Controlled Roadways granted by Lessee to others
from time to time, whether before or after the execution of this Lease, Lessee shall control the
Lessee Controlled Roadways, including, but not limited to, the exclusive right and power;

               (iii) To adopt from time to time and to enforce reasonable rules and regulations respecting
use of the Lessee Controlled Roadways by Lessee and others applied on a non-discriminatory basis;

               (iv) To adopt reasonable security measures designed to prevent or discourage use of the Lessee
Controlled Roadways by unauthorized people and to comply with Law, ordinances or regulations, as
applicable from time to time, for the operation and security of the Premises, including, but not
limited to, fencing and locked gates and imposition of background and identity checking and other
procedures for all or some persons entering upon the Premises, all of which shall be applied on a
non-discriminatory basis;

               (v) To close or restrict temporarily use of the Lessee Controlled Roadways or any portion
thereof as may be necessary in the event of any emergency, or to restrict temporarily to make
improvements to, or to repair, the Lessee Controlled Roadways, or for security or other legitimate
purposes (provided that any such non-emergency restrictions shall provide for reasonable
alternative access);

               (vi) To close, relocate, realign, replace, regrade, repave, improve, abandon, or demolish,
from time to time, all or any part of the Lessee Controlled Roadways, provided that

14

 

Lessee shall always and continuously during the Term provide reasonable means for Lessor’s
exercise of Lessor’s Access Rights;

               (vii) To grant easements over, and licenses to use, the Lessee Controlled Roadways or any
portion thereof to third parties chosen by Lessee; and

               (viii) To conduct, or contract for, all maintenance, repair, and improvement work on the
Lessee Controlled Roadways as Lessee, in its sole and absolute discretion, without detriment to
Lessor’s Access Rights, may determine is appropriate or necessary from time to time.

               (d) (i) As part of Lessor’s ongoing operations, Lessor may choose to vacate and/or abandon the
Aerojet Buildings and is able to do so subject to the obligations contained in this Lease.
Notwithstanding the foregoing, commencing on the fourth (4th) anniversary of the Term
Commencement Date, Lessee may, upon notice to Lessor, request that Lessor vacate and abandon in
place all of the Aerojet Buildings. Lessee shall provide Lessor with not greater than 14 months’
and not less than 12 months’ prior written notice of such request. Within 12 months of receipt of
such written request, Lessor shall remove all Hazardous Substances from the Aerojet Buildings, and
vacate and abandon in place all of the Aerojet Buildings, and leave such Aerojet Buildings in a
condition that shall not be an unsafe condition. Lessor’s Access Rights with respect to the use of
the Aerojet Buildings shall terminate upon such vacation and abandonment.

               (ii) In the event Lessee exercises its Purchase Option and takes fee title to the Demised
Land, at Lessee’s request, Lessor agrees to execute, acknowledge, and deliver to Lessee such grant
deed, and such other instruments and documents as Lessee shall reasonably request in order to
assure and show in the Official Records Lessee’s fee title to the Demised Land and the Aerojet
Buildings free of any interest or claim of Lessor. Prior to Lessee’s purchase of the Demised Land
pursuant to the Purchase Option, with respect to Aerojet Buildings that are not razed pursuant to
Section 2.8(d)(iii), Lessor shall remove all Hazardous Substances from such Aerojet Buildings, and
vacate and abandon in place all of the Aerojet Buildings, and leave such Aerojet Buildings in a
condition that shall not be an unsafe condition. Lessor’s obligations under this Section
2.8(d)(ii) shall survive the Term.

               (iii) Alternatively, at the time Lessee exercises its rights under the Purchase Option, Lessee
shall have the right at such time to request in a written notice to Lessor, that Lessor demolish
down to grade level, any or all of the then remaining Aerojet Buildings and remove the construction
debris from the Demised Land, all at Lessor’s cost. As part of such demolition, Lessor shall not
be obligated to remove any subsurface infrastructure. The parties agree that Lessor shall have
eighteen (18) months from the receipt of such notice to accomplish such demolition. Nothing in
this Section 2.8(d) shall diminish or limit Lessor’s obligations with respect to Hazardous
Substances under this Lease.

               (e) Upon the vacation and abandonment of each of the Aerojet Buildings, Lessor agrees to seal,
lock or otherwise secure such Aerojet Buildings (including in Lessor’s reasonable discretion,
fencing). Beginning on the Term Commencement Date, and ending on the

15

 

earlier of the Expiration Date and Lessee’s purchase of the Demised Land, Lessor will maintain
the Aerojet Buildings in a not unsafe condition, and Lessor shall defend, indemnify and hold
harmless fully Lessee for any and all claims, liabilities and losses caused by the Aerojet
Buildings or any Hazardous Substances therein.

               (f) On or after the Term Commencement Date and upon the terms and subject to the conditions
hereof, each of the parties hereto shall take, or cause to be taken, all appropriate action, and
do, or cause to be done, all things necessary, proper or advisable under Law and otherwise to carry
into effect the provisions of this Lease regarding the Reserved Uses with respect to the continued
existence of the Aerojet Buildings allowed on the Demised Land, including, without limitation,
executing such instruments or documents as are necessary or desirable.

               (g) Title to all fixtures, equipment, furnishings, and trade fixtures owned by Lessee upon the
Premises shall remain in Lessee, and replacements, substitutions, and modifications thereof may be
made by Lessee throughout the Term.

ARTICLE 3.

RENT

               3.1 Amount of Base Rent. In addition to any and all other amounts payable from Lessee
to Lessor pursuant to this Lease, Lessee agrees to pay to Lessor, and Lessor agrees to accept from
Lessee, as rent for the use and occupancy of the Demised Land, during the Term, a minimum annual
base rent equal to the parties’ good faith estimate of reasonable and actual costs incurred by
Aerojet in connection with the administration of this Lease, which the parties agree shall be Five
Thousand Dollars per year ($5,000) for the first five lease years, and Zero Dollars ($0) for the
remainder of the Term of the Lease (the “Base Rent”).

               3.2 Payment of Base Rent. The Base Rent shall be paid, in lawful money of the United
States of America, at such place or places as Lessor shall designate from time to time. The Base
Rent shall be paid in equal monthly installments, three months in advance, on the first
(1st) day of each month during that portion of the Term for which Base Rent is payable,
subject to prorations as follows:

                    (a) If the date as of which Base Rent commences to accrue is not the first (1st)
day of a calendar month, then a prorated portion, based upon a thirty (30)-day month, of Base Rent
shall be due and payable on the date as of which Base Rent commences to accrue; and

                    (b) If the date as of which the Term expires is not the last day of a calendar month, then the
last monthly payment of Base Rent during the Term shall be prorated, based upon a thirty (30)-day
month, to the date the Term expires.

               3.3 Additional Rent. This Lease is intended to be net to Lessor, and Lessee shall pay
to Lessor, net throughout the Term, the Base Rent prescribed by Section 3.1 free of any

16

 

offset, abatement, or other deduction, except as may be expressly set forth herein. Lessor
shall not be required to make any payment of any kind with respect to the Premises, except as may
be expressly set forth elsewhere in this Lease. Accordingly:

                    (a) Except as otherwise set forth herein, Lessee agrees to pay, to Lessor or the appropriate
party or governmental entity, as applicable (and such amounts payable to Lessor shall be deemed
“Additional Rent”), in addition to Base Rent, all other payments, costs, expenses, charges, and
other obligations of every kind whatsoever attributable to the Premises and the operation thereof,
including Lessee’s insurance premiums, real property taxes, assessments, and assessment
installments (excluding matters that are paid in connection with the Transition Services Agreement
between Lessor and Lessee dated as of the same date hereof (the “Transition Services Agreement”))
as they become due and payable during the Term; and

                    (b) Lessee shall make those payments, whether such payments are owned to Lessor or must be
made to a third party in order to fulfill an obligation of Lessee set forth in this Lease, at
whatever time is necessary to prevent delinquency or penalty for late payment unless Lessee has
duly contested said payments in the manner permitted and prescribed in this Lease. Lessor shall
invoice Lessee for any non-regularly scheduled sums payable to Lessor hereunder, which shall be due
no sooner than 30 days following Lessee’s receipt of such invoice.

               3.4 No Offset. All Base Rent and Additional Rent becoming owed to Lessor under this
Lease shall be due and payable without necessity of notice or demand and shall be paid without
offset or deduction of any kind, except as may be expressly provided elsewhere in this Lease.

               3.5 Interest on Arrearages. Lessee agrees to pay to Lessor interest on any Base Rent
or Additional Rent not paid within ten (10) days following receipt of notice from Lessor that such
amounts are past due, whether or not such amounts constitute rent, as follows:

                    (a) Said interest shall accrue from the date the rent or other amount becomes due and continue
until the rent or other amount is paid in full;

                    (b) Said interest shall become due and payable daily as it accrues, without necessity of
demand for payment, and shall be calculated at a rate equal to ten percent (10%) per annum, but in
no event shall such interest rate exceed the maximum interest rate allowed under the California
Usury Law; and

                    (c) Lessor may apply all payments received under this Lease first to interest accrued, and
second to delinquent rent and other monetary obligations.

               3.6 Refunds. If Lessor receives any refunds or rebates of any Additional Rent paid by
Lessee to Lessor under this Lease, Lessor will pay such refund or rebate (or Lessee’s pro rata
share of such refund or rebate, as reasonably calculated) to Lessee within five days after Lessor’s
receipt thereof. Lessor shall aid Lessee in all reasonable respects in obtaining any such refund
or rebate, provided that all costs of obtaining the same shall be paid by Lessee. Lessee

17

 

may, in its own name and at its own cost, contest with the applicable governmental entity the
full or partial amount of any tax or other charge (or any portion or subdivision thereof) for which
Lessee is responsible hereunder or the validity thereof. Lessor may contest with the applicable
governmental entity any such tax or charge concerning the Premises, so long as such contest also
relates to Lessor’s Property and does not disproportionately affect the Premises. Lessor and
Lessee will reasonably cooperate with each other in the event that either elects to challenge any
tax assessment or other governmental entity charge under this Section 3.6. In connection with the
foregoing, Lessor shall provide Lessee with assessor’s valuation notices promptly following the
receipt of same and shall provided Lessee with any assessor’s work sheets or such other information
as may be reasonably available relating to the taxes or other charges which are the subject of
Lessee’s challenge. Nothing in this Lease shall be construed to require either party to pay any
tax or governmental entity charge of any kind that is or may be imposed upon the other party, its
successors or assigns with respect to such other party’s property.

ARTICLE 4.

USE OF PREMISES

               4.1 Permitted Uses. Lessee shall use the Premises solely for the purposes of (i) the
Acquired Business and other pharmaceutical uses, such as developing, manufacturing, distributing,
and testing chemicals and their derivatives and uses and activities directly related thereto, such
as, but not limited to, laboratories and administrative offices, (ii) developing, manufacturing and
distributing aerospace products (but specifically excluding the right to conduct activities which
involve either perchlorate, trichloroethylene (TCE), or N-nitrosodimethylamine (NDMA) and/or (iii)
any lawful uses compatible with the Adjacent Development, (collectively, the “Permitted Uses”)
which may include uses which compete with other Lessor businesses or the Adjacent Development);
provided, however, that no use shall be considered a Permitted Use that would
impose on Lessor or any of its successors or assigns, an obligation to remedy or remove any
environmental contamination on the Demised Land or on property owned by Lessor or any of its
successors or assigns adjacent to the Demised Land to a standard or degree that exceeds the most
cost-effective, remedial alternative that is protective of human health and the environment and is
consistent with and meets the requirements of any applicable Environmental Law and any Governmental
Authority based upon the use of the property as industrial property. In all cases, such uses shall
be conducted in compliance with all Law and requirements herein. Except as provided above, Lessee
shall not use the Premises for any other use whatsoever without the prior written consent of
Lessor, which consent may be granted or withheld arbitrarily for any reason or no reason. Lessee’s
use of the Premises and Aerojet Site Adjoining Uses shall always be conducted with knowledge of,
and reasonable accommodation for, each other. In connection with said requirement for reasonable
accommodation for each other, and without limiting the generality of the foregoing provisions of
this Section 4.1, Lessor and Lessee agree specifically as follows:

                    (a) Lessor agrees not to voluntarily do, permit, or suffer any activity on that portion of the
Aerojet Site, whether located inside or outside the area of the Demised Land, that would cause
Lessee to violate or fail to comply with the Current Air Emissions

18

 

Requirements or that would expand the areas affected by the Quantity/Distance Restrictions as
provided in Exhibit “C”;

                    (b) Lessee agrees not to voluntarily do, permit, or suffer any activity on the Premises or any
portion thereof that would cause Lessor to violate or fail to comply with the Quantity/Distance
Restrictions or that would expand the area affected by the Air Emissions Requirements outside the
Demised Land plus those other portions of the Aerojet Site located within the areas of the radii
shown on Exhibit “D” attached hereto; and

                    (c) If infrastructure financing done in connection with Adjacent Development includes, or is
proposed by Lessor to include, imposition of Mello-Roos bonds or improvement bonds or assessments
or the creation of any special district or districts with any form of taxing authority which affect
the Demised Land, Lessee and Lessor agree to discuss the appropriate allocation, if any, of
responsibility for payment of such assessments based on the relative benefit to the Demised Land.
If the parties are unable to agree on an appropriate allocation of such assessments, the matter
will be submitted to an arbitrator appointed by Judicial Arbitration and Mediation Services, Inc.
(“JAMS”) on a date which is acceptable to both parties. The arbitration shall be conducted in San
Francisco, California in accordance with the procedures established by JAMS. Any determination by
the arbitrator shall be final and judgment and upon the award rendered by the arbitrator may be
entered in any court having jurisdiction. The parties hereby waive any right to appeal or
challenge such award in any court or otherwise. The parties shall each pay one half of the costs
and fees of the arbitrator and the cost of the arbitration. The obligations set forth in this
Section 4.1 shall survive the Term.

          4.2 Prohibited Uses. In no event shall the Premises or any portion thereof ever be
used for purposes defined in paragraph 11(B)(1) of the Partial Consent Decree or as may in the
future be defined as prohibited in any Governmental Decrees and Orders. Lessee agrees not to do or
permit anything to be done on or about the Premises and agrees not to bring or keep anything
thereon that constitutes a violation of Section 4.1 or a nuisance or constitutes waste or damages
to the Premises or any part thereof.

          4.3 Compliance with Law.

                    (a) Lessee shall not use the Premises or permit anything to be done in or about the Premises
that will in any material respect conflict with any law, whether that law be a state or federal
statute, an ordinance adopted by any city or county, a judicial or administrative decision,
including, but not limited, the Governmental Restrictions and the Governmental Decrees and Orders,
or any other governmental rule, regulation, permit, or requirement, and whether that law is now in
force or is hereafter adopted, and including the rules and requirements of any board of fire
insurance underwriters or equivalent (collectively, “Law”); provided that Lessor shall have given
Lessee reasonable notice of any applicable Governmental Restrictions in such manner so that Lessee
has the opportunity to comply. Without limiting Lessor’s obligations with respect to Hazardous
Substances under this Lease, Lessee shall, at its own cost and expense, promptly and properly
observe and comply with all Law relating to or arising from the use or occupancy, condition or
maintenance, improvement, or operation of the Premises or any part thereof that is from time to
time permitted to it under this Lease, and shall do all things required

19

 

to comply with all Law and to maintain all permits, licenses, certifications, and approvals
necessary and appropriate for the operation of the Premises or Lessee’s business.

                    (b) Except as set forth in Section 5.1(b) of Exhibit “G” hereto, (A) Lessee shall, at all
times, indemnify, defend, protect, and forever save Lessor harmless from and against all fines,
penalties, losses, damages, costs, expenses and other charges (including, but not limited to,
attorneys’ fees, court costs and other expenses incurred by Lessor in defending itself in
connection therewith, including those on appeal) imposed for or resulting from any violations by
Lessee or any of its employees, agents, representatives, lessees, sublessees, licensees, or
contractors at, on, or about the Premises, of any Law; and (B) Lessor shall, at all times,
indemnify, defend, protect, and forever save Lessee harmless from and against all fines, penalties,
losses, damages, costs, expenses and other charges (including, but not limited to, attorneys’ fees,
court costs and other expenses incurred by Lessee in defending itself in connection therewith,
including those on appeal) imposed for or resulting from any violations by Lessor or any of its
employees, agents, representatives, lessees, sublessees, licensees, or contractors at, on, or about
the Premises, of any Law.

                    (c) The judgment of any court of competent jurisdiction or the admission of either party in
any action against such party, that such party has violated any Law shall be conclusive of the fact
as between Lessor and Lessee.

               4.4 Utilities. Except as otherwise specifically set forth in this Section 4.4, and
subject to a Force Majeure (including the failure on the part of the underlying provider of such
services (i.e., SMUD; Pacific Gas & Electric; and Folsom)) Lessor shall provide all the utilities
set forth below. Lessee shall pay for all utilities and services that Lessee uses at or about the
Demised Land during the Term, including, without limitation, all water, natural gas, electricity,
telephone, and other utilities and services supplied to the Premises, and except with respect to
those utilities and services for which Lessee is required to pay to Lessor hereunder, only to the
extent that if not paid, any of the foregoing can become a lien on Lessor’s interest in the Demised
Land, together with any and all taxes thereon, and for any and all hook up charges and cost of
installation of utility lines and meters (including, but not limited to, the costs of bringing such
utilities to the Demised Land, if any, and if at the action of Lessee) only to the extent that any
of the forgoing, if not paid can become a lien on Lessor’s interest in the Demised Land. To the
extent such charges are regularly scheduled payments from Lessee to Lessor and can be calculated in
advance, Lessee shall make such payments to Lessor three (3) months in advance. Respecting the
provision of water, electricity, and natural gas to the Premises, Lessor and Lessee agree
specifically as follows:

                    (a) From Lessor’s supplies of water delivered pursuant to its agreements with the City of
Folsom, as those agreements currently exist or are, from time to time, amended or re-negotiated by
Lessor and the City of Folsom (or, at Lessor’s option, a comparable replacement source), Lessor
shall, subject to the provisions of Section 4.4(f), to provide to Lessee at and for the Premises,
during the Term, up to ten thousand (10,000) gallons per day of potable water and up to fifty
thousand (50,000) gallons per day of non-potable water and Lessee agrees to reimburse Lessor
monthly for Lessee’s proportionate share (based upon the ratio of the quantity of Lessee’s use
compare to the quantity of total use) of Lessor’s supply costs

20

 

incurred at the rates set forth in said agreements with the City of Folsom. To the extent
that water deliveries under said agreements with the City of Folsom are terminated or reduced,
Lessor and Lessee agree to work cooperatively with each other, using commercially reasonable
efforts, in attempting to identify and arrange for replacement water, and if replacement water is
arranged, Lessor and Lessee shall each pay its fair share of all costs incurred in securing and
delivering such replacement water;

                    (b) Lessor, at its sole cost and expense, shall install and maintain, for so long as Lessor
has an obligation to and does supply water under Section 4.4(a), water meters, at a location
mutually agreed upon by Lessor and Lessee, serving the Premises, for measuring and monitoring water
usage, which installation shall be effected as soon as reasonably practical following mutual
execution hereof. Following installation of such meters, for so long as Lessor has the obligation
to and does supply water under Section 4.4(a), Lessee shall pay to Lessor, Lessee’s proportionate
share of the cost for such water as reimbursement to Lessor for providing water to the Premises, as
set forth in (a) above. All payments under this Section 4.4(b) shall be paid, in arrears, at the
end of each month during the Term, prorated, based upon a 30-day month, for any partial months at
the beginning and ending of the Term;

                    (c) Subject to the provisions of Section 4.4(f), Lessee shall, with respect to natural gas, be
responsible for obtaining and paying directly for, Lessee’s metered supply from Pacific Gas &
Electric or other provider through lines crossing the Aerojet Site. Lessor covenants and agrees to
maintain such lines (to the extent not maintained by PG&E or any successor public utility) and to
provide any and all necessary easements to the natural gas provider sufficient for such existing
lines, or in Lessor’s discretion, such replacement lines, crossing the Aerojet Site. To the extent
that such lines entering the Demised Land carrying natural gas purchased by Lessee also supply
natural gas to buildings that are either Aerojet Buildings or are located outside the area of the
Demised Land, Lessor shall reimburse Lessee for its proportionate share of the cost to Lessee of
such natural gas. Said reimbursement shall be paid in arrears, at the end of each month during the
Term, prorated based upon a 30-day month, for any partial months at the beginning and ending of the
Term. When and to the extent any of such buildings are no longer used by Lessor’s proportionate
share shall be adjusted;

                    (d) Subject to the provisions of Section 4.4(f), Lessor shall, with respect to electricity, be
responsible for supplying and paying (subject to reimbursement by Lessee as provided below)
directly for, the supply currently in place from the Sacramento Municipal Utility District through
lines crossing the Aerojet Site, and Lessee shall install a meter on said lines from the Prairie
City Substation, at a location reasonably acceptable to Lessee and Lessor. If Lessor is required
to pay for such electricity directly to SMUD, Lessee shall reimburse Lessor, within twenty (20)
days after presentation of each invoice, for Lessee’s share of SMUD’s charges for electricity. To
the extent that such lines also supply electricity to buildings that are either Aerojet Buildings,
Aerojet Temporary Use Buildings or are located outside the area of the Demised Land, Lessee shall
not be responsible for (and Lessee may deduct from its said reimbursement to Lessor) Lessor’s
proportionate share of such electricity. Said reimbursement shall be paid, in arrears, at the end
of each month during the Term, prorated, based upon a thirty (30)-day month, for any partial months
at the beginning and ending of the

21

 

Term. When and to the extent any of such buildings are no longer used by Lessor’s
proportionate share shall be adjusted;

                    (e) Lessee’s rights under this Section 4.4 with respect to utilities (“Lessee’s Utilities
Rights”) shall be deemed to be an easement appurtenant to Lessee’s interests in the Premises and a
covenant real, running with the land that Lessor shall have no right to terminate or restrict
during the Term (or subsequent to the Term if Lessee acquires fee title to the Premises), subject
to the following provisions:

                         (i) Lessee’s Utilities Rights are non-exclusive;

                         (ii) Said easement for Lessee’s Utilities Rights shall be exercised initially over, and
encumber only, the areas described in Exhibit “K” attached hereto and made a part hereof; provided
that Lessor reserves the right to change the description set forth in Exhibit “K” at any time, and
from time to time, and upon any such change, Lessee’s Utilities Rights shall be exercised over, and
encumber only, the new area as chosen by Lessor. Any such change in the area described in Exhibit
“K” shall be effective when Lessor gives to Lessee written notice thereof. Promptly upon request
by Lessor, Lessee shall execute and deliver an amendment to this Lease setting forth in a new
Exhibit “K” describing the new area for exercise of Lessee’s Utilities Rights as so changed by
Lessor; and

                    (f) Notwithstanding any other provision of this Section 4.4, Lessee and Lessor acknowledge
that Adjacent Development may include installation of additional public utility lines, including
water, natural gas, and electricity. Lessor and Lessee agree to coordinate reasonably with each
other concerning Lessee’s transition to said public utilities. In connection therewith, in the
event public utility lines become available within a one thousand (1,000) foot radius of the point
at which the existing utility lines enter the Demised Land, then either Lessor or Lessee shall have
the right to cause to be installed all infrastructure necessary for the public utilities to deliver
to Lessee the utilities contemplated by this Section 4, and, in connection therewith, Lessor shall
execute and record reasonable easement agreements for such infrastructure that are appurtenant to
and run with the Demised Land. The party exercising such right shall bear all costs and expenses
in connection with the installation of such infrastructure as well as all reasonable third-party
costs and expenses associated with the preparation and recording of such easements. In the event
public utilities that are functionally equivalent to those currently used in connection with the
Acquired Business are installed and made available to Lessee from a public utility company in
accordance with this Section 4.4(f), then Lessor shall have no further obligations to Lessee, under
subparts (a) through (e) of this Section 4.4 (except for reimbursement of utility use in Aerojet
Buildings), all easements granted pursuant to Section 4.4(e) hereof (but not any easements granted
in connection with this Section 4.4(f)) shall cease to exist, and Lessee shall have no further
obligations to Lessor under such subparts, and Lessee shall, at its sole cost and expense, arrange
for obtaining its utility services exclusively from such public utility provider.

               4.5 Sewer Outfall. Subject to the last sentence of this Section 4.5, to the extent
the sewer outfall commonly used in connection with the Acquired Business operated at the Premises
as of the Term Commencement Date, identified in the Acquired Business’s

22

 

discharge permit as “SRCSD manhole #072-023-018,” (“Sewer Outfall”) is located on
the Aerojet Site, then Lessor shall permit Lessee to use such Sewer Outfall and Lessee’s Access
Rights shall be deemed to include reasonable and sufficient access to and from the Sewer Outfall;
provided that Lessor reserves the right at any time, and from time to time, to substitute a
functionally equivalent alternative sewer outfall on the Aerojet Site to which Lessee has
reasonably equivalent access (a “Substitute Sewer Outfall”) and upon any such change, Lessee’s
rights hereunder shall be exercised with respect to such Substitute Sewer Outfall. Lessor shall,
during the Term, reasonably maintain the Sewer Outfall or the Substitute Sewer Outfall, as
appropriate. Each party shall indemnify, defend, protect, and hold harmless the other party from
and against any liability to the extent arising out of such party’s wastewater discharge. Lessee
shall reimburse Lessor for Lessee’s pro-rata share of the costs of wastewater discharge based upon
the measured volume of wastewater discharged by Lessee, as compared to the measured volume of all
wastewater discharged from the Aerojet Site. In the event a public sewer on fair and
non-discriminatory terms which would provide adequate service to the Acquired Business is installed
by Lessor as part of the Adjacent Development to the boundary of the Demised Premises, then Lessee
shall, at its sole cost and expense, arrange for the connection to and the use thereof and upon
such connection Lessor shall have no further obligations to Lessee under this Section 4.5.

               4.6 Entry by Lessor. In addition to any and all other rights of entry granted or
reserved to Lessor by this Lease, Lessee agrees to permit Lessor, its agents, representatives,
contractors, and licensees to enter the Demised Land at all reasonable times upon reasonable
advance written notice (with accommodations as may be necessary to enable Lessee to have a
representative accompany Lessor) (i) to post notices of nonresponsibility; and (ii) to perform
Lessor’s obligations and exercise Lessor’s rights under this Lease; provided, however, that except
as provided elsewhere in this Lease, in the event of an emergency, (a) Lessee may require that a
representative of Lessee be present during any such entry, (b) such entry shall comply with
Lessee’s reasonable security measures, (c) such entry shall not unreasonably interfere with
Lessee’s access to, use or occupancy of the Premises, (d) such entry shall not adversely affect the
rights of Lessee or Lessee’s Mortgagee hereunder, and (e) such entry shall not cause any Lessee
Material Adverse Effect. The obligations set forth in this Section 4.5 shall survive the Term with
but only respect to Lessor’s duties set forth in Exhibit “G”.

               4.7 Additional Restrictions. Notwithstanding anything contained in this Lease to the
contrary, Lessee shall not have any possessory or other right to any groundwater at the Demised
Land or at the Aerojet Site and, as amplification of the forgoing, Lessee shall not have any right
to access, extract, use or produce groundwater from the Demised Land or the Aerojet Site. Without
limiting the forgoing, with respect to the Demised Land or any of the Aerojet Site, Lessee shall
not (i) drill any extraction or injection wells; (ii) extract any groundwater or inject any fluids
into any existing wells; or (iii) construct any unlined ponds. The obligations set forth in this
Section 4.6 shall survive the Term.

               4.8 Control of Premises. Except as specifically provided in this Lease, or as
specifically provided for in Section 4.5, (i) Lessee shall have complete control over the planning,
design, engineering, development, commissioning, construction, management, operation and
maintenance of the Premises; (ii) Lessor shall have no liability or responsibility whatsoever for

23

 

any repairs made by or for Lessee to the Premises or for any aspects of the future design,
development or construction by or for Lessee on the Premises; and (iii) Lessee may, without
Lessor’s consent, modify or destroy any part of the Premises at its expense and in its sole
discretion at any time upon providing prior written notice to Lessor, provided that such
modification or destruction does not result in a Lessor Material Adverse Effect. Lessee will
complete any such modification or destruction without cost or expense to Lessor, and Lessee shall
secure final certificates of occupancy or equivalent use certificates or permits, if required, with
regard to the Premises and any improvements thereto.

               4.9 Adjacent Development. Lessee, on behalf of itself and its Affiliates, successors
and assignees, agrees not to object, publicly or privately, to, encourage or support others in
objecting to, or take any action for the purpose of impeding or delaying, Adjacent Development or
land use entitlements, subdivisions, improvements, or uses that are part of Adjacent Development.
The preceding sentence shall not be construed to prohibit or limit any person or entity, or impose
any liability on such person or entity due to from (i) responding to any inquiry by a governmental
authority for information;(ii) reporting suspected illegal activity to any governmental authority;
(iii) responding to any legal process, including by way of example, subpoena, deposition,
interrogatories or the like; or (iv) otherwise performing an act required by law. The sole remedy
for a violation of this prohibition shall be an action for damages, and shall not constitute a
default under this Lease. The obligations set forth in this Section 4.8 shall survive the Term.

ARTICLE 5.

PROPERTY TAXES

               5.1 Definition. For purposes of this Lease, the term “Property Taxes”:

                    (a) means and includes all taxes, assessments, and other governmental charges of every kind
and nature whatsoever, whether general or special, ordinary or extraordinary, including, but not
limited to, assessments for public improvements or benefits and bonds, including, but not limited
to Mello-Roos bonds, issued to finance such improvements or benefits, that have been heretofore or
shall be during the term of this Lease as allocated to Lessee as provided in Section 4.1(c) hereto
(i) assessed, levied, or imposed upon, or become due and payable and a lien upon, the Premises or
any part thereof; or (ii) assessed, levied, or imposed by reason of the use or occupancy or change
in ownership of the Premises or any part thereof; or (iii) assessed, levied, or imposed upon this
Lease or Lessee’s rental obligations or Lessor’s right to receive rents or other sums under this
Lease; or (iv) subject to (b) below, assessed, levied, or imposed by reason of Lessor’s ownership
or interest in all or any part of the Premises, this Lease, or rents or other sums accruing under
this Lease, including, but not limited to, a tax or excise on rents; or (v) assessed, levied, or
imposed in lieu of any of the foregoing taxes, assessments, or other governmental charges; or (vi)
assessed by reason of any Improvements made for or on behalf of Lessee; but

24

 

                    (b) does not mean or include franchise, estate, inheritance, successor, capital levy,
transfer, net income, or excess profit taxes imposed upon Lessor, nor does the term “Property
Taxes” include any taxes, assessments, or other governmental charges assessed, levied, or imposed
upon, or attributable to the value of Lessor’s ownership of, the Aerojet Buildings; and

                    (c) if, at any time during the Term of this Lease, any portion of the Premises is jointly
assessed, for property tax purposes, with other real property that is not a part of the Premises,
then Lessor and Lessee shall make a reasonable allocation of the taxes, assessments, or other
governmental changes that are assessed, levied, or imposed thereon, and only the portion thereof
reasonably attributable to the Premises shall be deemed Property Taxes payable by Lessee as set
forth in Section 5.2, which allocation may be based upon any and all records, memoranda, and notes
available at the Assessor’s Office, calculations of respective square footage, evaluation of
respective permanent improvements and uses, and other relevant evidence available to Lessor at no
substantial cost or provided by Lessee. Lessor shall provide Lessee with written evidence of
Lessor’s payment of any taxes, charges or assessments affecting the Premises which Lessor is
obligated to pay at least three (3) business days prior to delinquency. If Lessor fails to pay any
such taxes, charges or assessments, Lessee shall have the right to pay such taxes, charges or
assessments and deduct the amount of such payment from Base Rent.

               5.2 Payment.

                    (a) Lessee agrees to pay to Lessor or the appropriate governmental entity, as applicable,
prior to delinquency, as Additional Rent additional to all other rent reserved in this Lease, all
Property Taxes for each fiscal tax year or portion thereof that is within the Term, for each fiscal
tax year that is not entirely within the Term in the same ratio as the number of days of such
fiscal tax year that are within the Term bears to the number of such days that are outside the
Term.

                    (b) With respect to Property Taxes that may, under the Law then in force, be paid in
installments, Lessee shall be required to pay hereunder only such installments, prorated between
Lessor and Lessee for partial fiscal tax years as above provided.

                    (c) In the event that Lessee fails to pay any Property Taxes, Lessor shall have the right and
option, but no obligation, to pay such Property Taxes or any portion thereof before or after the
delinquency date and any and all fines, penalties, and interest thereon, and Lessee agrees to
reimburse Lessor immediately for the total amount so paid by Lessor, as Additional Rent additional
to all other rent reserved in this Lease.

                    (d) In the event that Lessor has paid, before the Term Commencement Date, any Property Taxes
or installment thereof for a fiscal tax year or portion thereof that is in part within the Term,
Lessee agrees to pay to Lessor, on the Term Commencement Date, Lessee’s prorata portion thereof.

25

 

                    (e) Notwithstanding anything contained in this Section 5.2 to the contrary, for the first
three (3) years of the Term, Lessor agrees to pay one-half (1/2) of that portion of Property Taxes
attributable to said three (3) years that is the amount of the increase in Property Taxes triggered
by the change in ownership effected by the execution and delivery of this Lease.

               5.3 Personal Property Taxes.

                    (a) Lessee agrees to pay, or cause to be paid, directly to the taxing authority or authorities
before delinquency, any and all taxes that are levied or assessed upon Personal Property.

                    (b) If any such taxes upon Personal Property are assessed, levied, or imposed upon Lessor or
upon all or any part of the Premises or on Lessor’s interest in the Premises or this Lease, or if
such taxes upon Personal Property become a lien upon or may be enforced against Lessor or all or
any part of the Premises or against Lessor’s interest in the Premises or in this Lease, Lessor
shall as soon as practicable notify Lessee of same, and Lessor shall have the right and option, but
no obligation, to pay such taxes upon Personal Property or any portion thereof before or after the
delinquency date, and Lessee agrees to reimburse Lessor immediately therefor, including, but not
limited to, any and all late payment penalties or fines and interest paid by Lessor, as Additional
Rent additional to all other rent reserved in this Lease.

               5.4 Contests. Nothing herein shall prevent Lessee from contesting, and Lessee may
contest and institute all proceedings reasonably necessary to contest, in good faith, the validity
or amount of any Property Taxes, including, but not limited to, any applicable or potentially
applicable exemptions from Property Taxes, provided Lessee protects the Premises and the interests
of Lessor by payment by Lessee of the Property Taxes under protest not later than thirty (30) days
before delinquency, and provided, further, that Lessee shall indemnify, defend, protect, and hold
harmless Lessor from and against any liability for the payment of said Property Taxes. Lessor
shall aid Lessee in all reasonable respects in obtaining any such refund or rebate, provided that
all costs of obtaining the same shall be paid by Lessee. In connection with the foregoing, Lessor
shall provide Lessee with assessor’s valuation notices promptly following the receipt of same and
shall provided Lessee with any assessor’s work sheets or such other information as may be
reasonably available relating to the taxes or other charges which are the subject of Lessee’s
challenge. Notwithstanding anything to the contrary herein, Lessee may postpone payment of any
contested tax, assessment or other charge pending timely prosecution of any such challenge and
appeals of any ruling related thereto. Nothing in this Lease shall be construed to require either
party to pay any tax or governmental entity charge of any kind that is or may be imposed upon the
other party, its successors or assigns with respect to such other party’s property.

               5.5 Survival. The obligations set forth in this Article 5 shall survive the Term.

26

 

ARTICLE 6.

INDEMNITY AND INSURANCE

          6.1 Lessee’s Indemnity.

          (a) Except to the extent the same arise from Lessor’s actions or omissions, Lessee agrees to
indemnify, defend, and protect Lessor and its agents and employees from and against and hold Lessor
and its agents and employees harmless and free from any and all liability, loss, cost, expense, or
obligation (including without limitation reasonable attorneys’ fees, court costs, and other
expenses, including those of appeal) on account of or arising out of, injury to or death of any
person or persons or damage to or loss of use of property, from whatever cause, occurring during
the Term, in any way connected with the condition of, or Lessee’s maintenance or use of, the
Premises, the alteration or improvement of the Premises (including without limitation, the
demolition of Improvements and the construction of New Improvements), or the Personal Property or
connected with any activities of Lessee or of any of its employees, agents, sublessees, invitees,
contractors, or licensees, including, without limitation, any and all liability for injury to or
death of, or damage to or loss of the use of the property of, Lessee or any of Lessee’s employees,
agents, invitees, contractors, or licensees

               (b) Nothing contained in this Section 6.1 shall apply to, or affect in any way, Lessor and
Lessee’s obligations and rights respecting, any Release, threat of Release, or the presence of any
Hazardous Substance, all of which are governed by other provisions of this Lease, particularly by
Sections 2.5 and 5.1 of Exhibit “G”. The obligations set forth in this Section 6.1 shall survive
the Term.

          6.2 Liability Insurance.

               (a) Lessee agrees to procure and maintain, at its sole cost and expense, during the Term,
commercial general liability insurance, occurrence basis, as broad as the most common generally
available ISO Commercial General Liability, policy form CG 00 01, insuring against liabilities
related to the condition of or use of the Premises in an amount that is not less than Two Million
Dollars ($2,000,000.00), combined single limit, for bodily injury or death and for damage to or
loss of use of property. Tenant shall also maintain an umbrella policy in excess of the foregoing
coverages in an amount not less than Fifteen Million Dollars ($15,000,000.00). Such insurance
shall be subject to periodic increases as provided below and shall specifically (i) insure
performance by Lessee of its indemnity obligations under Section 6.1; (ii) provide that the
coverage is primary and that any coverage that Lessor or any mortgage holder may maintain shall be
in excess thereof; (iii) name Lessor and such mortgage holder as additional insureds; (iv) provide
that the policy cannot be canceled or modified without thirty (30) days’ prior written notice to
Lessor and to the mortgage holder; and (v) include a cross-liability or severability-of-interests
endorsement in the event that the basic policy obtained by Lessee does not contain such a
provision, which cross-liability or severability-of-interests endorsement shall apply to all
additional insureds, as well as the named insureds, and shall be referenced in the additional
insureds endorsement. Any self-insured retention respecting said liability insurance shall not
exceed Five Hundred Thousand Dollars ($500,000) per occurrence.

27

 

               (b) Neither the maintenance nor the amount of any such general liability insurance shall be
construed to limit in any way Lessee’s obligations under any indemnity, defense, or hold harmless
agreements set forth in this Lease.

               (c) At the request of Lessor, the amount of said general liability insurance shall be
increased periodically as may be reasonable, from time to time (but not more than once in any two
year period), based upon advice from a professional insurance consultant selected by Lessor and
approved by Lessee, to an amount equal to that which customarily would be carried for a business
similar to the Acquired Business and a lease of similarly-situated property and usage.

               (d) Lessee shall also procure such other insurance as may be required by applicable Law.
Lessee shall also from time to time procure any modifications to or endorsements for the insurance
policies provided for in this Lease as may reasonably be required in order to adequately insure
against the risks contemplated in this Article 6 in a manner comparable to other prudent operators
of comparable facilities, including increases in the amounts of insurance coverage as may be
appropriate in Lessee’s reasonable judgment to reflect inflation.

          6.3 Waiver of Subrogation. Lessee and Lessor each hereby release and relieve the
other from, and if and to the extent permitted by their insurance policies, waive their entire
right of recovery against the other for, direct or consequential loss or damage arising out of or
incident to the perils covered by the property insurance carried by such party, whether due to the
negligence of Lessor or Lessee or their agents, employees, or invitees. If necessary, all property
insurance policies, if any, maintained by Lessor or Lessee, shall be endorsed to so provide.
Lessee and Lessor each waive any rights to recover indirect, consequential, punitive, special or
exemplary damages or any claim for a multiplier effect or any capitalization of out-of-pocket
expenses or lost profits, provided, however, that the foregoing shall not be construed to preclude
recovery by the indemnified party in respect of losses directly incurred from third-party claims.
Each of Lessee and Lessor shall use commercially reasonable efforts to mitigate their damages.

          6.4 General. Each insurance policy required by this Lease to be procured and
maintained by Lessee shall be issued by a company authorized to do insurance business in the State
of California, having a rating in Best’s Key Rating Guild of not less than A-VII. Lessee agrees to
deliver to Lessor (i) on or before the Term Commencement Date, a copy of each such policy, or
binder therefor, and a certificate certifying that it contains the provisions required by this
Lease, and (ii) not later than five (5) days prior to the expiration of the policy, a renewal
binder therefor.

          6.5 Lessor’s Insurance. During the Term of this Lease, Lessor shall maintain general
liability, workers’ compensation and employer’s liability, and business automobile liability
insurance, covering Lessor’s operations and activities on the Aerojet Site, use of the Aerojet
Buildings and Lessor’s exercise of Lessor’s Access Rights.

28

 

          6.6 Environmental Remediation and Related Matters. The parties’ respective
obligations regarding environmental remediation, environmental matters and related matters are set
forth in Exhibit “G” which is incorporated herein by reference in its entirety. Such obligations
shall survive the Term if Lessee acquires fee title to the Premises.

ARTICLE 7.

MAINTENANCE AND REPAIRS

          7.1 Lessor’s Obligations. Lessor shall keep the Aerojet Buildings in as good a
condition, and repair as at the Term Commencement Date, and free from hazards, including
replacements as needed. Subject to the foregoing and except as otherwise set forth in this Lease,
Lessor shall not be obligated to make or bear the cost of any repairs, replacements, rebuilding, or
renewals of any kind, nature, or description whatsoever related to the Premises or any portion
thereof, except to the extent such maintenance, repair or replacement is required as a result of
the negligence or willful misconduct of Lessor or its agents, employees, representatives, invitees,
guests, contractors, subcontractors or any other Person acting for or on behalf of Lessor.

          7.2 Lessee’s Obligations.

               (a) Except to the extent that the demolition of Improvements by Lessee is permitted under
Article 8, and subject to other provisions of this Lease that govern the maintenance and repair of
utility lines and the Roadways, and the obligations of Lessor with respect to Pre-Term
Environmental Liabilities, Lessee shall, at its own cost, and without expense to Lessor, keep and
maintain the Premises in good condition, and repair, and free from hazards, including replacements
as needed (provided that nothing herein shall require Lessee to improve the Premises or any part
thereof to a better condition than exists as of the Term Commencement Date.).

               (b) Lessee hereby waives the benefit of any Law that would otherwise accord Lessee the right
to make repairs at Lessor’s expense or to terminate this Lease because of Lessor’s failure to keep
the Premises or any portion thereof in good order, condition, or repair.

          7.3 Surrender of the Premises.

     (a) The parties acknowledge that Lessee owns fee title to the AFC Buildings and all of the
Lessee Improvements. Lessor shall have no rights or obligations with respect to the Lessee
Improvements, except as expressly provided in the Lease; provided that Lessor agrees to execute,
acknowledge and record from time to time such additional written documents of conveyance and
assignment as may be required by any title insurance company for the issuance to Lessee or Lessee’s
Mortgagee of a title insurance policy showing Lessee to be the fee owner of any such Lessee
Improvements. Upon the expiration or termination of the Term, Lessee shall quit and surrender the
Premises to Lessor in their then “As-Is” “Where-Is” condition, subject only to the obligations of
Lessee pursuant to the terms and conditions elsewhere in this Lease. Notwithstanding the
foregoing, Lessee shall not leave any of the Lessee Improvements,

29

 

including but not limited to the AFC Buildings, in an unsafe condition. Lessee agrees to
execute, acknowledge, and deliver to Lessor such quitclaim deed and such other instruments and
documents as Lessor shall reasonably request in order to assure and show in the Official Records
Lessor’s fee title to the Demised Land and the AFC Buildings free of any interest or claim of
Lessee or Lessee’s mortgagee.

     (b) Title to all fixtures, equipment, furnishings, and trade fixtures owned by Lessee upon the
Premises shall remain in Lessee, and replacements, substitutions, and modifications thereof may be
made by Lessee throughout the Term.

ARTICLE 8.

CONSTRUCTION ACTIVITIES

          8.1 Construction of New Improvements and Construction in General. Subject to the
terms of this Lease, and in accordance with all Law and Government Restrictions, Lessee is, in the
course of operating the Premises, authorized to do all things necessary to construct, operate,
maintain and adapt the Acquired Business or Lessee’s other lawful use, including, but not limited
to, making new improvements (including buildings, structures, fixtures, equipment, paving,
landscaping and other physical improvements), removing, razing and/or destroying such improvements,
trees, plants, shrubs, and topsoil located on the Premises and making such excavations as Lessee
may deem necessary, subject to the provisions of this Lease, including, without limitation, this
Article 8. Lessee may (but is not obligated to) construct New Improvements upon the Demised Land
and Lessee may demolish, alter, and make additions to Lessee’s Improvements and replace obsolete
Lessee’s Improvements; provided that all such construction activities, as well as any rebuilding or
restoration of damaged or destroyed Improvements under Article 9, shall comply with the following
requirements:

               (a) All New Improvements and all such demolitions, alterations, and additions shall be
designed and constructed in a good and workmanlike manner and in accordance with Law, this Lease,
and with approval by the PCD Agencies, to the extent required by Law.

               (b) The design and construction of all such New Improvements and all such demolitions,
alterations, and additions shall comply with all Law and with all Governmental Decrees and Orders.

               (c) At Lessee’s sole cost and expense, Lessor will (i) notify the PCD Agencies of Lessee’s
proposed designs and drawings or demolition, alteration, or construction plans and (ii) seek the
approval of the PCD Agencies pursuant to paragraph 11 of the Partial Consent Decree or other
applicable Governmental Decrees and Orders, all prior to the commencement of any construction
activities at the Premises.

30

 

               (d) No New Improvement or the use thereof shall expand the area affected by the Air Emissions
Requirements outside the area of the Demised Land plus the Current Air Emissions Requirements
Boundaries.

               (e) Lessee, at Lessee’s sole cost and expense, shall procure all necessary permits, approvals,
and other authorizations that may be necessary or appropriate, including, but not limited to,
compliance with the requirements of Section 2.5 of Exhibit “G” hereto, and shall reimburse Lessor
for its direct costs and expenses incurred in submitting designs, drawings, and plans to, and
seeking the approval of, the PCD Agencies.

               (f) Lessee shall diligently prosecute such construction.

               (g) The entire cost of construction of all New Improvements and of accomplishing such
demolitions, alterations, and additions, including, but not limited to, any off site work, plans
and specifications, and all permits, fees, and licenses therefore, shall be paid by Lessee.

               (h) In the event Lessee desires to locate a New Improvement on the Demised Land in accordance
with the terms of this Lease and all Law and Government Restrictions, and there exist Hazardous
Substances (that are Pre-Term Environmental Liabilities) at, on or under that portion of the
Demised Land chosen by Lessee for the location of such New Improvement, then Lessor and Lessee
shall cooperate in identifying an alternative location for such New Improvement where there are
fewer or no such Hazardous Substances (that are Pre-Term Environmental Liabilities) present and
where such location would allow Lessee to comply with the terms of Section 8.1(d) and the other
provisions of this Lease. If after consultation with Lessor, Lessee cannot locate a New
Improvement on the Demised Land in compliance with Section 8.1(d) due to the presence of Hazardous
Substances (that are Pre-Term Environmental Liabilities), then the parties shall cooperate in
identifying another location on the Demised Premises, including a location that would otherwise
cause Lessee to breach the terms of Section 8.1(d). Such alternative location will be mutually
agreed to by Lessor and Lessee and shall be chosen with goal of reducing the impact on Aerojet Site
Adjoining Uses and the Adjacent Development or plans. Lessor shall be responsible for the
additional cost, if any, incurred by Lessee to locate such New Improvement to the alternative
location rather than the location selected initially by Lessee.

          8.2 Relocation of Utilities. Lessee shall be responsible, at Lessee’s sole cost and
expense, for obtaining all agreements, consents, and permits that may be required to relocate any
utility improvement that may be necessary or appropriate in connection with the construction and
installation of any New Improvements or any demolitions, alterations, or additions.

          8.3 Personal Property. Personal Property may be removed from the Premises by Lessee
at any time during the Term and shall be removed from the Premises by Lessee upon the expiration or
termination of the Term.

          8.4 Liens and Notices of Violation Prohibited. Lessee shall not enter into any
contract or agreement that purports to permit any contractors, subcontractors, or materialmen

31

 

engaged by Lessee with respect to the Premises to make, file, or maintain a mechanic’s or
other lien or claim of any kind or character against any real property or personal property of
Lessor, including Lessor’s Property and any other property interest owned, held, occupied, or
otherwise possessed by Lessor or its affiliates, for or on account of any labor, materials,
fixtures, tools, machinery, equipment, or any other things furnished, or any other work done or
performance given under, arising out of, or in any manner connected with Lessee’s ownership or
operation of the Acquired Business (or other Permitted Uses) or possession of the Premises (such
liens or claims being collectively referred to herein as “Liens”). If any Lien is made, filed or
maintained against the fee interest in the Demised Land, Lessee shall within thirty (30) days
following Lessor’s written request therefore either contest such Lien by appropriate proceedings
which operate to preclude the enforcement of such Lien during the pendency of such contest, or
obtain and maintain a mechanics’ lien release bond or such other bond as shall result in the
removal of any Lien under applicable law, or otherwise address the Lien in a commercially
reasonable manner. Lessee shall not have any liability hereunder under any circumstances for any
lien or claim filed by any person for or on account of any labor, materials, fixtures, tools,
machinery, equipment, or any other things furnished, or any other work alleged to be done or
performed by or on behalf of Lessor.

          8.5 Mechanics’ Liens.

          (a) Lessee agrees:

          (i) To pay for all labor, services and materials used by or furnished to Lessee or any
contractor employed by Lessee with respect to the Premises or any part thereof, whether or not such
labor, services, or materials were related to trade fixtures or other works of improvement;

          (ii) to indemnify, defend, and protect Lessor and the Premises from and against, and to hold
Lessor and the Premises free and harmless from, any and all liabilities, claims, liens,
encumbrances, and judgments created or suffered in connection with such labor, services, or
materials; and

          (iii) to permit Lessor to post and maintain notices of nonresponsibility on the Premises in
accordance with California Civil Code Section 3094 or other similar statute hereafter enacted;
provided that, nothing herein shall prevent Lessee from contesting in good faith the validity or
amount of any lien, claim, encumbrance, or judgment, provided that, in the case of a mechanics’ or
materialman’s lien, Lessee obtains and records an appropriate bond as provided by Law to remove the
record lien created thereby.

          (b) Should a judgment on any lien, charge, encumbrance, order, notice or violation be rendered
against the Premises for which Lessor is not responsible hereunder, and should Lessee fail to
discharge such judgment or take action to protest such judgment as provided herein, Lessor shall
have the right, but not the obligation, to discharge said judgment. If Lessor exercises that
option, any amount paid by Lessor shall be due from Lessee as Additional Rent, and subject to
interest as provided above. Lessor shall be responsible for any lien, charge, encumbrance, order,
notice or violation rendered against the Premises arising out of

32

 

any work performed by or on behalf of Lessor or any contractor on behalf of Lessor, except to
the extent such work is performed as a result of Lessee’s failure to comply with its obligations as
provided in this Lease.

          8.6 Permits or Approvals. Except as otherwise provided in any provision of this
Lease, Lessor agrees to join with Lessee, at Lessee’s request, at Lessee’s sole cost and expense,
as required for any permits, applications and other governmental approvals related to, and Lessee
agrees to indemnify and hold Lessor harmless from and against all liabilities arising from such
joinder by Lessor with Lessee in connection with, Lessee’s construction of New Improvements or any
demolitions, alterations, or additions, at no cost or expense to Lessor excepting any requirements
of the PCD Agencies as to which Lessor shall be responsible.

          8.7 Signs. Lessee may, without cost or expense to Lessor, at any time and from time
to time during the Lease Term, place or permit to be placed signs on or about the Premises (and at
the applicable entrances to the Aerojet Site, in locations reasonably acceptable to Lessor), and to
remove them or permit them to be removed, provided the same is done in full compliance with all
Law, Government Restrictions and requirements pertaining thereto. Lessor hereby agrees to execute
any applications and consents that are required by Law with regard to such signs, provided that
Lessee reimburses Lessor for any actual external cost it is required to pay to a third party upon
delivery by Lessor to Lessee of written documentation, in reasonable detail, evidencing Lessor’s
payment of such cost.

ARTICLE 9.

DESTRUCTION

          9.1 Rebuild. In the event that Lessee’s Improvements or any of them are damaged or
destroyed in whole or in part by any casualty, whether or not covered by insurance, Lessee may, in
its sole and absolute judgment, elect to rebuild or restore them with such alterations as Lessee
may reasonably desire, subject to compliance with Article 8. In the event Lessee elects not to
rebuild or restore such Lessee’s Improvements, it shall have the option to terminate this Lease,
effective as of ninety (90) days from the date such damage or destruction occurs, which option may
be exercised only by giving to Lessor, within said ninety (90) days, a written notice of
termination. Lessor and Lessee shall have no further obligations to each other after said
effective date of termination respecting the Premises, except those obligations that, by the terms
of this Lease or provisions of Law, shall survive the termination of this Lease.

          9.2 No Abatement of Rent. Unless this Lease is terminated by Lessee as provided in
Section 9.1, there shall be no abatement of rent by reason of damage to or destruction of the
Premises in whole or in part. Lessee hereby waives the provision of Section 1932, Subdivision 2,
and Section 1933, Subdivision 4, of the California Civil Code, and all present and future
amendments thereto, and all other Law that would permit or cause termination of a lease or
abatement of rental obligations upon damage to or destruction of the property subject thereto.

33

 

          9.3 Insurance Proceeds. All insurance proceeds payable with respect to Lessee’s
Improvements shall be payable to Lessee and Lessor shall have no interest in such proceeds.

ARTICLE 11.

DEFAULT AND REMEDIES

          11.1 Default Defined. For the purposes of this Lease, the terms “Default by Lessee”
and “Lessee’s Default” both mean the occurrence of any one or more of the following events:

          (a) failure of Lessee to pay any Base Rent and Additional Rent within thirty (30) days after
Lessee receives notice from Lessor that such Base Rent and Additional Rent are past due;

          (b) breach by Lessee of any provision of this Lease, except those mentioned in subpart (a) of
this Section 11.1, not cured within sixty (60) days after Lessor gives Lessee (and Lessee receives)
written notice of the breach, or, in the case of breaches reasonably requiring more than sixty (60)
days to cure, not cured within a reasonable time after the giving of such notice, provided that the
curing of the breach is commenced within said sixty (60) days after the giving of such notice and
is diligently prosecuted to completion thereafter.

36

 

          11.2 Lessor’s Right to Terminate. Subject to the rights of Lessee’s Mortgagee herein,
in the event of a Default by Lessee, Lessor shall have, in addition to any other remedies now or
later available to Lessor at law or equity, the right to terminate this Lease and Lessee’s right to
possession of the Premises by giving written notice of termination to Lessee and Lessee’s Mortgagee
(and if no minimum notice is specified in this Lease, then Lessor will provide not less than sixty
(60) days’ written notice, to Lessee and Lessee’s Mortgagee, of its intention to terminate this
Lease) and to recover from Lessee:

               (a) the worth at the time of award (computed by including interest at the rate specified
elsewhere in this Lease for arrearages) of the unpaid Base Rent and Additional Rent required to be
paid by Lessee under this Lease that had been earned at the time of termination;

               (b) the worth at the time of award (computed by including interest at the rate specified
elsewhere in this Lease for arrearages) of the amount by which the unpaid Base Rent and Additional
Rent required to be paid by Lessee under this Lease that would have been earned after termination
until the time of award exceeds the amount of such rental loss that Lessee proves could have been
reasonably avoided;

               (c) the worth at the time of award (computed by discounting at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent (1%)) of the amount by
which the unpaid Base Rent and Additional Rent required to be paid by Lessee under this Lease for
the balance of the Term after the time of award exceeds the amount of such rental loss that Lessee
proves could be reasonably avoided; and

               (d) any and all other amounts necessary to compensate Lessor for detriment proximately caused
by the Default by Lessee or which in the ordinary course of events would be likely to result
therefrom.

Notwithstanding the foregoing, Lessor shall have no right to terminate this Lease as a result of
the bankruptcy or insolvency of Lessee, so long as Base Rent, Additional Rent and other obligations
hereunder are being paid and satisfied in accordance with this Lease.

          11.3 Lessor’s Right Not to Terminate. Unless and until Lessor elects to terminate
this Lease and Lessee’s right to possession as provided in Section 11.2, this Lease shall continue
in full force and effect after Default by Lessee, and Lessor may enforce all of its rights and
remedies under this Lease, including, but not limited to, the right to recover or enforce payment
of Base Rent and Additional Rent as they become due under this Lease.

          11.4 Extension of Cure Periods. In the case of a bona fide dispute between Lessor and
Lessee regarding whether a Default by Lessee has actually occurred, the cure periods set forth
above shall be extended by the amount of time reasonably necessary to resolve such dispute in
accordance with the provisions of Section 15.16.

          11.5 General. Efforts by Lessor to mitigate damages caused by any Default by Lessee
shall not constitute a waiver by Lessor of any of Lessor’s rights or remedies under this

37

 

Lease, and nothing contained in this Lease shall affect the right of Lessor under this Lease
to indemnification for liability for personal injuries or property damages arising prior to
termination of this Lease. Neither reasonable acts of repair, alteration, maintenance, reletting,
or preservation of the Premises, nor the appointment of a receiver or trustee, whether in
bankruptcy proceedings or otherwise, upon initiative of Lessor to protect Lessor’s interests under
this Lease, shall constitute an election by Lessor to terminate this Lease or Lessee’s right to
possession of the Premises. If Lessor permits this Lease to continue in full force and effect
after a Default by Lessee, Lessor may, nevertheless, at any time thereafter elect to terminate this
Lease (after following the procedures set forth above) and Lessee’s right to possession of the
Premises under the provisions of Section 11.2, for such previous Default by Lessee, provided the
Default by Lessee has not then been cured. The rights and remedies of Lessor under this Article 11
shall be additional to all other rights and remedies provided to Lessor in this Lease or by law,
whether now in force or hereafter enacted, including, but not limited to, injunctions and other
equitable relief.

          11.6 Lessor’s Default. If Lessor shall be in default hereunder, then Lessee, after
sixty (60) days written notice that Lessee intends to cure such default, or without notice if in
Lessee’s reasonable judgment an emergency shall exist, shall have the right, but not the
obligation, to cure such default, and Lessor shall pay to Lessee upon demand the reasonable cost
thereof. If Lessor shall default or fail in the performance in any respect of a covenant or
agreement on its part to be performed under this Lease, and such default shall not have been cured
for a period of sixty (60) days after receipt by Lessor of written notice of said default from
Lessee, or if such default cannot, with due diligence, be cured within sixty (60) days, and Lessor
shall not have commenced the remedying thereof within such period or shall not be proceeding with
due diligence to remedy it with thirty (30) days following the initial sixty (60) day period (it
being intended in connection with a default not susceptible of being cured by Lessor with due
diligence within sixty (60) days that the time period within which to remedy the same shall be
extended for an additional thirty (30) days), then Lessee may declare Lessor in default of this
Lease upon written notice to Lessor, seek any compensatory damages which may be available to Lessee
in an action at law or equity, and in addition to its other remedies, cure any default of Lessor at
Lessor’s cost and deduct the cost of such cure from Base Rent.

          11.7 Right of Lessor to Perform. Subject to the rights of Lessee’s Mortgagee herein,
Lessor may, but shall not be obligated, to make any payment or perform any obligation required of
Lessee under this Lease that Lessee fails timely to pay or perform as provided herein, and Lessor
may do so with or without giving further notice of Lessor’s intention to do so. No such payment or
performance by Lessor shall constitute a waiver of, or release Lessee from, Lessee’s said
obligation or any other obligation of Lessee under this Lease, nor shall such payment or
performance by Lessor diminish or affect in any way other rights and remedies of Lessor set forth
elsewhere in this Lease that may be applicable by reason of such failure by Lessee to pay or
perform its obligation.

38

 

ARTICLE 12.

LOAN OR SALE

          12.1 Estoppel Certificates, etc. Each party (both Lessor and Lessee) agrees within
twenty (20) days following request by the other to execute and deliver to the requesting party an
estoppel certificate (i) certifying that this Lease is unmodified and in full force and effect, or,
if modified, stating the nature of such modification and certifying that this Lease, as so
modified, is in full force and effect, and certifying the date to which the Base Rent and
Additional Rent and any other charges are paid in advance, if any, and (ii) acknowledging that
there are not, to such party’s knowledge, any uncured defaults on the part of either party
hereunder, or specifying such defaults if they are claimed) evidencing the status of this Lease.
The statement shall also state the dates to which the Base Rent and Additional Rent has been paid
in advance. The statement shall be such that it can be relied on by any other auditor, creditor,
commercial banker, and investment banker of either party and by any prospective purchaser or
encumbrancer of the Premises or Improvements or both or of all or any part or parts of Lessee’s or
Lessor’s interests under this Lease.

          12.2 Liability of Transferee. In the event that Lessor shall sell or otherwise
transfer its title to the Premises, after the effective date of such sale or transfer, and upon
assumption of Lessor’s obligations hereunder, whether expressly or by operation of law, Lessor
shall have no further liability under this Lease to Lessee except as to matters of liability which
have accrued before, and are unsatisfied as of, the date of sale or transfer, and Lessee shall
thereafter seek performance solely from Lessor’s successor.

ARTICLE 13.

MORTGAGE HOLDER PROTECTIONS

          13.1 Subordination or Superiority. The rights of Lessee under this Lease shall be
superior to any mortgage or deed of trust (including a consolidated mortgage or deed of trust)
constituting a lien on Lessor’s title to the Premises, whether such mortgage or deed of trust has
heretofore been, or may hereafter be, executed by Lessor (any such mortgage herein called an
“Underlying Encumbrance”). To further assure the foregoing superiority, prior to the Term
Commencement Date and as a condition to Lessor’s rights and Lessee’s obligations under this Lease
(or any new lease executed pursuant to Section 13.5(k)), Lessor shall either (a) obtain a release
of any and all existing Underlying Encumbrances with respect to the Premises, or (b) obtain an SNDA
from each holder of an existing Underlying Encumbrance in form and substance acceptable to Lessee
and Lessee’s Mortgagee providing for the unqualified recognition of Lessee’s and Lessee’s
Mortgagee’s interests under this Lease (or any new lease executed pursuant to Section 13.5(k)), and
each of their respective successors and assigns, in the event of a foreclosure of such holder’s
security interest so long as no a Default by Lessee has occurred and is continuing hereunder. All
future Underlying Encumbrances shall contain clauses acceptable to Lessee and Lessee’s Mortgagee
which automatically subordinate the lien of such Underlying Encumbrance not only to the lien of
this Lease but to that of any new lease executed pursuant to

39

 

Section 13.5(k). Nothing herein shall be construed to give the holder of any Underlying
Encumbrance any right, title or interest in or to, or any lien on or security interest in, any
rights or interests of Lessee under or created by this Lease, including without limitation Lessee’s
leasehold estate and the fee interest of Lessee in any buildings, improvements or personal property
now or hereafter situated on or used in connection with the Premises.

          13.2 Attornment. Subject to the rights of Lessee’s Mortgagee hereunder, Lessee agrees
(i) to attorn to any Mortgage Holder and to any party acquiring title to the Premises or any
portion thereof by judicial foreclosure, trustee’s sale, or deed in lieu of foreclosure, and (ii)
to execute an attornment agreement reasonably acceptable to Lessee and Lessee’s Mortgagee to
confirm same.

          13.3 SNDA Form. Lessor and Lessee agree to act reasonably with each other and with
the Mortgage Holder in reviewing and approving the SNDA form described in Section 13.1 above, and
agree that the Mortgage Holder and Lessee shall be entitled to have the customary protections
expected in such an agreement, including provisions on subject matters that are not expressly
mentioned in this Lease.

          13.4 Mortgage Holder’s Right to Cure Lessor’s Defaults. In the event of any default
on the part of Lessor under this Lease, Lessee agrees to give notice by certified mail to any
Mortgage Holder whose address shall have been furnished to Lessee, and offer such Mortgage Holder,
except in the case of emergency, a reasonable opportunity, not to exceed thirty (30) days (or such
longer period as is specifically required under this Lease), to cure the default, which cure period
shall be in addition to any cure period provided Lessor hereunder.

          13.5 Leasehold Mortgage.

          (a) Notwithstanding anything to the contrary in this Lease regarding any assignment of this
Lease, but subject to the provisions of this Section 13.5, Lessee shall have the right at any time
and from time to time to encumber the leasehold estate created by this Lease and Lessee’s
Improvements during the Term by mortgage, deed of trust or other security instrument, including,
without limitation, an assignment of the rents, issues and profits from the Premises (a “Leasehold
Mortgage”), to secure repayment of a loan (and associated obligations) made to Lessee by an
Institutional Lender for any purpose whatsoever; provided that the Leasehold Mortgage shall contain
an express acknowledgment and agreement by the mortgagee that its interest are subject to all of
the terms and conditions of this Lease. Lessee shall deliver to Lessor not later than thirty (30)
days prior to, and promptly after, execution by Lessee a true copy of any Leasehold Mortgage, and
any amendment, modification or extension thereof, together with the name and address of the owner
and holder thereof (“Lessee’s Mortgagee”).

          (b) During the continuance of any Leasehold Mortgage until such time as the lien of such
Leasehold Mortgage has been extinguished, and if a true copy of such Leasehold Mortgage shall have
been delivered to Lessor together with a written notice of the name and address of Lessee’s
Mortgagee, Lessor shall not do or agree to any of the following without the prior written consent
of Lessee’s Mortgagee: (A) mutually terminate or accept any voluntary

40

 

surrender of this Lease (except upon the expiration of the Term), or (B) consent to any
material amendment or modification of this Lease.

          (c) Notwithstanding any default by Lessee in the performance or observance of any covenant,
condition, or agreement of this Lease on the part of Lessee to be performed or observed, Lessor
shall have no right to terminate this Lease even though a Default by Lessee under this Lease shall
have occurred and be continuing, unless and until Lessor shall have given Lessee’s Mortgagee
written notice of such Default by Lessee and Lessee’s Mortgagee shall have failed to remedy (it
being agreed that Lessee’s Mortgagee shall not be obligated to remedy) such default or to acquire
Lessee’s leasehold estate created hereby or to commence foreclosure or other appropriate
proceedings in the nature thereof, all as set forth in, and within the time specified by, this
Section 13.5.

          (d) Lessee’s Mortgagee shall have the right, but not the obligation, at any time prior to
termination of this Lease, and without any additional penalty therefor, to pay all of the rents due
hereunder, to provide any insurance, to pay any taxes and make any other payments, to make any
repairs and improvements and do any other act or thing required of Lessee hereunder, and to do any
act or thing which may be necessary and proper to be done in the performance and observance of the
covenants, conditions and agreements hereof to prevent the termination of this Lease. All payments
so made and all things so done and performed by Lessee’s Mortgagee shall be as effective as the
same would have been if made, done and performed by Lessee instead of by Lessee’s Mortgagee, and
shall be accepted by Lessor.

          (e) Should any Default by Lessee under this Lease occur, Lessee’s Mortgagee shall have sixty
(60) days after receipt of notice from Lessor setting forth the nature of such Default by Lessee,
and, if the default is such that possession of the Premises may be reasonably necessary to remedy
the default, a reasonable time after the expiration of such sixty (60) day period, within which to
remedy such default (it being agreed that Lessee’s Mortgagee shall not be obligated to remedy such
default), provided that (A) Lessee’s Mortgagee shall have fully cured any default in the payment of
any monetary obligations of Lessee under this Lease within such sixty (60) day period and shall
continue to pay currently such monetary obligations as and when the same are due, and (B) Lessee’s
Mortgagee shall have acquired Lessee’s leasehold estate created hereby or commenced foreclosure or
other appropriate proceedings in the nature thereof within such sixty (60) day period or prior
thereto, and shall be diligently and continuously prosecuting any such proceedings to completion.
All rights of Lessor to terminate this Lease, as against Lessee’s Mortgagee, as the result of the
occurrence of any such Default by Lessee shall be subject to and conditioned upon Lessor having
first given Lessee’s Mortgagee written notice of such Default by Lessee and Lessee’s Mortgagee
having failed, within said limited period, to remedy such default or acquire Lessee’s leasehold
estate created hereby or commence foreclosure or other appropriate proceedings in the nature
thereof as set forth in and within the time period specified by this Section 13.5(e).

          (f) A Default by Lessee under this Lease which in the nature thereof cannot be remedied by
Lessee’s Mortgagee shall be deemed to be remedied if (A) within sixty (60) days after receiving
written notice from Lessor setting forth the nature of such Default by Lessee, Lessee’s Mortgagee
shall have acquired Lessee’s leasehold estate created hereby or commenced

41

 

foreclosure or other appropriate proceedings in the nature thereof, (B) Lessee’s Mortgagee
shall diligently and continuously prosecute any such proceedings to completion, (C) Lessee’s
Mortgagee shall have fully cured any default in the payment of any monetary obligations of Lessee
under this Lease which do not require possession of the Premises within such sixty (60) day period
and shall thereafter continue to faithfully perform all such monetary obligations which do not
require possession of the Premises, and (D) after gaining possession of the Premises, Lessee’s
Mortgagee shall perform all of the obligations of Lessee hereunder as and when the same are due.

          (g) If Lessee’s Mortgagee is prohibited by any process or injunction issued by any court or by
reason of any action by any court having jurisdiction of any bankruptcy, debtor rehabilitation or
insolvency proceedings involving Lessee from commencing or prosecuting foreclosure or other
appropriate proceedings in the nature thereof, the times specified in subparagraphs (f) and (g)
above for commencing or prosecuting such foreclosure or other proceedings shall be extended for the
period of such prohibition; provided that Lessee’s Mortgagee shall have fully cured any default in
the payment of any monetary obligations of Lessee under this Lease and shall continue to pay
currently such monetary obligations as and when the same fall due, and provided that Lessee’s
Mortgagee shall diligently attempt to remove any such prohibition.

          (h) Lessor shall mail to Lessee’s Mortgagee a duplicate copy by certified mail of any and all
notices which Lessor may from time to time give to or serve upon Lessee pursuant to the provisions
of this Lease; and no notice by Lessor to Lessee hereunder shall be deemed to have been given
unless and until a copy thereof has been mailed to Lessee’s Mortgagee. Lessee’s Mortgagee shall
have the right to give notices on behalf of Lessee.

          (i) Foreclosure of a Leasehold Mortgage or any sale thereunder, whether by judicial
proceedings or by virtue of any power of sale contained in the Leasehold Mortgage, or any
conveyance of the leasehold estate created hereby from Lessee to Lessee’s Mortgagee by virtue or in
lieu of foreclosure or other appropriate proceedings in the nature thereof, shall not require the
consent of Lessor or constitute a breach of any provision of or a default under this Lease. Upon
such foreclosure, sale or conveyance, Lessor shall recognize Lessee’s Mortgagee, or any other
foreclosure sale purchaser, as Lessee hereunder. In the event Lessee’s Mortgagee becomes Lessee
under this Lease or under any new lease obtained pursuant to Section 13.5(j), Lessee’s Mortgagee
shall be liable for the obligations of Lessee under this Lease or such new lease only for the
period of time that Lessee’s Mortgagee is the Lessee hereunder or thereunder. This Lease or any
new lease shall be freely assignable by Lessee’s Mortgagee or any other foreclosure sale purchaser.
In the event Lessee’s Mortgagee subsequently assigns or transfers its interest under this Lease
after acquiring the same by foreclosure or by an acceptance of a deed in lieu of foreclosure or
subsequently assigns or transfers its interest under any such new lease, and in connection with any
such assignment or transfer Lessee’s Mortgagee takes back a mortgage or deed of trust encumbering
such leasehold interest to secure a portion of the purchase price given to Lessee’s Mortgagee for
such assignment or transfer, then such mortgage or deed of trust shall be considered a Leasehold
Mortgage as contemplated under this Section 13.5 and Lessee’s Mortgagee shall be entitled to
receive the benefit of this Section 13.5 and any other provisions of this Lease intended for the
benefit of the holder of a Leasehold Mortgage. During the pendency

42

 

of any foreclosure or sale proceedings, Lessor will recognize and give effect to any and all
subleases covering any portion of the Premises, so long as the sublessees thereunder are not in
default under their respective subleases.

          (j) Should this Lease be terminated by reason of any default by Lessee hereunder, Lessor
shall, upon written request by Lessee’s Mortgagee to Lessor received within sixty (60) days after
such termination, execute and deliver a new lease of the Demised Land to Lessee’s Mortgagee for the
remainder of the term of this Lease with the same covenants, conditions and agreements (except for
any requirements which have been satisfied by Lessee prior to termination) as are contained herein,
and which new lease shall be freely assignable by Lessee’s Mortgagee (or its assignee), in all
cases subject to the provisions of paragraph 11 of the PCD and any Governmental Restrictions.
Together with the execution and delivery of such new lease of the Premises, Lessor shall, at the
request of Lessee’s Mortgagee, deliver to Lessee’s Mortgagee a quitclaim deed respecting Lessee’s
Improvements for the term of such new lease. Lessor’s obligation to enter into such new lease of
the Premises with Lessee’s Mortgagee shall be conditioned as follows: (A) Lessee’s Mortgagee has
remedied and cured all monetary defaults hereunder and has remedied and cured or has commenced and
is diligently completing the cure of all nonmonetary defaults of Lessee susceptible to cure by any
party other than by the original Lessee, and (B) Lessee’s Mortgagee shall pay or cause to be paid
all actual and reasonable costs and expenses of Lessor, including, without limitation, reasonable
attorneys’ fees, real property transfer taxes and any escrow fees and recording charges, incurred
in connection with the preparation and execution of such new lease and any conveyances related
thereto.

ARTICLE 14.

ASSIGNMENT AND SUBLETTING

          14.1 Generally Forbidden. Except as permitted under Section 14.2, or upon the written
consent of Lessor, which consent shall not be unreasonably withheld or delayed, this Lease and
Lessee’s interests under this Lease shall not be assigned or otherwise transferred or delegated by
Lessee, in whole or in part, nor shall Lessee sublet or permit or suffer any third party to occupy
or use all or any portion of the Demised Land or the Premises. Any attempt to effect such an
assignment or other transfer or delegation or such a subletting or third-party occupancy or use,
without Lessor’s prior written consent, or in violation of Section 14.2, shall be null and void.
The foregoing prohibition of any assignment shall apply fully to an assignment by operation of law.
For purposes hereof, sales, transfers or assignments of (i) a controlling interest in the shares
of Lessee if Lessee is a corporation that is not publicly traded, or (ii) general partnership
interests sufficient to control management decisions if Lessee is a partnership, or (iii) the
majority or controlling underlying beneficial interest if Lessee is any other form of business
entity, are forbidden by this Section 14.1.

          14.2 Permitted Transactions. Notwithstanding the provisions of Section 14.1, and
subject to approval under paragraph 11 of the PCD and any applicable Governmental Restrictions,
Lessee shall have the right and power to assign, in whole or in part, its interests

43

 

under this Lease (a) to any person or entity that is concurrently acquiring substantially all
of the business assets of Lessee, whether structured as an “assets” sale or a sale of voting equity
interests in Lessee; or (b) to any business entity that controls, is controlled by, or is under
common control with Lessee, with the word “control” meaning beneficial ownership of equity
interests with voting power that are sufficient to dictate management and all business decisions of
the entity in question; provided that no such assignment shall be effective except after at least
thirty (30) days have elapsed from the date Lessor is given by Lessee written notice of the
proposed assignment together with a copy of the proposed instrument of assignment; provided further
that Lessee shall deliver to Lessor a copy of the fully executed assignment within ten (10) days
after it is executed by Lessee and delivered to the assignee.

          14.3 Miscellaneous Provisions. No assignment by Lessee shall release Lessee from
Lessee’s obligations under this Lease or alter the primary liability of Lessee to pay Base Rent and
Additional Rent and to perform all other obligations to be performed by Lessee hereunder. The
acceptance of Base Rent and Additional Rent by Lessor from any other person shall not be deemed to
be a waiver of Lessor of any provision of this Article 14. In the event of default by an assignee
in the performance of any of the terms hereof, Lessor may proceed directly against Lessee without
the necessity of exhausting remedies against such assignee.

          14.4 Partial Consent Decree. Any assignee, sublessee, or transferee will be bound by
the terms of Exhibit G, as well as the restrictions set forth in Paragraph 11 of the PCD.

ARTICLE 15.

providing prior written notice thereof to the other party as specified in this Section 15.5, which
notice shall be deemed effective ten (10) days following delivery of the change of address. Except
as expressly provided herein to the contrary, failure to deliver a courtesy copy of any notice
shall not be deemed to be a default hereunder, nor shall such failure have any effect on the

courtesy copy of any notice(s) to such parties.

          15.6 Attorneys’ Fees. In the event that legal proceedings are commenced to enforce or
interpret any of the terms or conditions of this Lease, for breach of any such terms or conditions,

fixed by the court, whether incurred at the trial court level or on any appeal, in addition to all
other relief to which prevailing party may be entitled.

          15.7 Successors. Without limiting or otherwise affecting any restrictions on
assignments of this Lease or rights or duties under this Lease, this Lease and all of its terms and

hiring, and use of the Premises; provided, however, that in the event that any easements described

parties hereto, or their respective successors or assigns.

          15.9 Severability. If any provision of this Lease or the application thereof to any
person or circumstances shall to any extent be held in any proceeding to be invalid or
unenforceable, the remainder of this Lease shall be valid and enforceable to the fullest extent

frustrate the parties essential objectives as expressed herein.

          15.10 Construction. No provision of this Lease shall be construed against or
interpreted to the disadvantage of either Lessor or Lessee by any court or other governmental or
judicial authority by reason of such party’s having or being deemed to have structured, written,

the Law of the State of California, not including choice of law rules and principles.

          15.12 Time is of Essence. Time is of the essence of this Lease.

46

 

          15.13 No Joint Venture. Nothing in this Lease shall be construed to render or
constitute Lessor in any way or for any purpose a partner, joint venturer or associate in any
relationship with Lessee other than that as landlord and tenant, nor shall this Lease be construed
to authorize either party to act as agent for the other party except as expressly provided to the
contrary in this Lease.

          15.14 Counterparts. This Lease may be executed in any number of counterparts, all of
which together shall be deemed one and the same instrument, and each of which counterparts shall be
deemed an original of this Lease for all purposes notwithstanding that less than all of the
signatures may appear on any one counterpart.

          15.15 Recordation. Lessor and Lessee agree to record this Lease in its entirety,
including all exhibits attached to this Lease, in the Official Records at or after the Term
Commencement Date. Lessor and Lessee further agree that:

          (a) This Lease is not intended to, and does not, encumber, or affect, in any way, property
other than (i) the Demised Land (as described in Exhibit “A”), which Demised Land includes the only
portion of the area described in Exhibit “C” that is affected by this Lease; (ii) the area within
the Current Air Emissions Requirements Boundaries (as described in Exhibit “D”); (iii) the Roadways
(subject to the provisions of Sections 2.1, 2.2, and 2.3, including Exhibit “I”); (iv) the land
described in Exhibit “K”; and (v) the Improvements (collectively, the “Encumbered Property”).

          (b) If any provisions of this Lease appears to be contrary to, or in conflict with, any of the
provisions of Section 15.15(a), then, and notwithstanding any other provision of this Lease, the
provisions of Section 15.15(a) shall control over such apparently contrary or conflicting other
provisions. All rights and obligations of Lessor and Lessee under this Lease are personal rights
and obligations of Lessor and Lessee that do not run with, and are not binding upon successors in
interest to, any property that is not part of the Encumbered Property.

          (c) Lessor and Lessee agree, upon request by either of them, from time to time, promptly to
provide further assurances, including, but not limited to, certifications, estoppel letters,
quitclaim deeds, affidavits, amendments to this Lease, or other proof or comfort, addressed to
Lessor or Lessee, as the case may be, or to third parties, including, but not limited to, title
insurance companies and prospective buyers, lessees, and lenders having or anticipating interests
in any property that is not within the Encumbered Property, that: (i) such property is not part of
the Encumbered Property and is not burdened or benefited by this Lease or any provision of this
Lease; and (ii) as and when, as provided elsewhere in this Lease, from time to time, the area of
the Encumbered Property becomes changed or some portion of the Encumbered Property becomes released
from the burdens of this Lease, that such change or release has occurred and such property is no
longer Encumbered Property.

47

 

          15.16 Dispute Resolution.

          (a) If a dispute arises between the parties arising from or related to this Lease, the dispute
resolution processes set forth in this Section 15.16 shall govern the resolution of such dispute.

          (b) The parties shall attempt in good faith to resolve any controversy, claim arising out of
or relating to this Lease or the construction, interpretation, performance, breach, termination,
enforceability or validity thereof (a “Dispute”) promptly by negotiation between executives who
have authority to settle the Dispute (“Senior Party Representatives”).

          (c) Either party may give the other party written notice (a “Controversy Notice”) of any
Dispute which has not been resolved in the normal course of business. Within fifteen (15) days
after delivery of the Controversy Notice, the receiving party shall submit to the other a written
response (the “Response”). The Controversy Notice and the Response shall include (i) a statement
setting forth the position of the party giving such notice and a summary of arguments supporting
such position, and (ii) the name and title of such party’s Senior Party Representative and any
other persons who will accompany the Senior Party Representative at the meeting at which the
parties will attempt to settle the Dispute. Within thirty (30) days after delivery of the
Controversy Notice, the Senior Party Representatives of both parties shall meet at a mutually
acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to
resolve the Dispute. All reasonable requests for information made by one party to the other will
be honored.

          (d) If the Senior Party Representatives meet and are unable to reach an agreement on the
dispute within thirty (30) days after delivery of the Controversy Notice, the parties agree to
attempt in good faith to resolve such dispute using the mediation services of JAMS. The mediation
will be conducted by a mutually agreeable mediator from the San Francisco office of JAMS. The
costs of the mediator and other JAMS’ costs shall be shared equally by the parties. Any settlement
reached by mediation shall be recorded in writing, signed by the parties, and shall be binding on
them. In no event shall the existence of a dispute or disagreement between Lessor and Lessee, or
their consultation under this Section 15.16 to attempt to resolve it, delay the filing or
submission of any document, or the performance of any action or activity, beyond the legally
required deadline nor prevent either party from pursuing any remedy to which it is entitled under
the indemnification portion of this Agreement.

          (e) All negotiations pursuant to this Section 15.16 shall be treated as compromise and
settlement negotiations. Nothing said or disclosed, nor any document produced, in the course of
such negotiations that is not otherwise independently discoverable shall be offered or received as
evidence or used for impeachment or for any other purpose in any current or future arbitration.

          (f) If the Dispute has not been resolved within sixty (60) days after delivery of the
Controversy Notice, or if the parties fail to meet within thirty (30) days after delivery of the
Controversy Notice as hereinabove provided, either party may initiate arbitration of the Dispute as
provided in subpart (g) of this Section 15.16.

48

 

          (g) If the Dispute is not resolved as provided in Section 15.16(b) – (d), then either party
may initiate arbitration proceedings by providing the other party written notice of such initiation
of arbitration (“Arbitration Notice”). If the parties are unable to agree upon an arbitrator and a
time and place for the arbitration within twenty (20) business days of the Arbitration Notice, the
party who sent the Arbitration Notice may arrange for arbitration in San Francisco before an
arbitrator appointed by JAMS on a date which is acceptable to both parties; provided however, that
such date may not be later than forty-five (45) Business Days after the Arbitration Notice, or as
soon thereafter as the schedule of the arbitrator(s) permit. The arbitration shall be conducted in
San Francisco, California in accordance with the procedures established by JAMS. Any determination
by the arbitrator shall be final and judgment upon the award rendered by the arbitrator may be
entered in any court having jurisdiction. The parties hereby waive any right to appeal or
challenge such arbitrable award in any court or otherwise. The parties shall each pay one half of
the costs and fees of the arbitrator and the cost of the arbitration.

          15.17 Proceedings. Nothing in Section 15.16 shall prohibit either party from
initiating litigation or other judicial or administrative proceedings if such party would be
substantially harmed by a failure to act during the time that such good faith efforts are being
made to resolve the Dispute through negotiation or mediation. In the even that litigation is
commenced under this Section 15.17, the parties agree to continue to attempt to resolve any Dispute
according to the terms of Section 15.16 during the course of such litigation proceedings under this
Section 15.17.

          15.18 Confidentiality. If Lessor and Lessee shall obtain, or seek to obtain, from the
other, as a result of their respective rights and obligations under this Lease, any material or
information obtained from the other which is specifically and reasonably determined by the other
party as confidential information, the parties shall promptly enter into a confidentiality
agreement reasonably acceptable to each party to govern the use and disclosure of such information.

COPY OF PARAGRAPH 11 OF

THE PARTIAL CONSENT DECREE

11. RESTRICTIONS ON USE AND TRANSFER OF LAND

     (A) Within fifteen (15) days after the effective date of this Decree, Aerojet shall present to
the Court for execution an “order re: Partial Consent Decree.” The Order shall be recorded with
the office of the Sacramento County Recorder (“Recorder”) within fifteen (15) days after issuance.
The Order re: Partial Consent Decree shall state:

   “There is a Partial Consent Decree (“Decree”) which affects:

(1) the land described in Exhibit I-1 to the Decree (“Exhibit I-1 land”); (2) the
land identified in Exhibit I-5 of the Decree; (3) portions of Exhibit I-1 and
Exhibit I-5 land described in Exhibits I-6 and I-7. Exhibits I-1, I-5, I-6 and I-7
to the Decree are attached and incorporated as part of this Order.

   The Decree was entered on __________, 19___, in the consolidated actions United
states, et al. v. Aerojet-General Corporation, et al., No. CIVS 86-0063-EJG, and
People of the State of California ex rel John K. Van De Kamp on behalf of
Department of Health Services and Regional Water Quality Control Board, Central
Valley Region v. Aerojet General Corporation et al., No. CIVS 86-0064-EJG, in
the United States District Court for the Eastern District of California, and a copy
of the Decree can be found in the files of that court. The Decree contains a
restriction on use and transfer of the property in Paragraph 11 as follows:

The Order re: Partial Consent Decree shall then quote the entirety of Subparagraphs 11(B) through
11(N).

F-1

 

     (B) Aerojet will not make any of the following uses on any land described in Exhibit 1-6
(“Exhibit I-6 land”) without first giving notice to and obtaining approval of DHS or,
alternatively, a determination by the Court favorable to Aerojet pursuant to Subparagraph 11(D).

          (1) Build or use any structure as a residence, hospital for humans, school for persons under
21 years of age, a day care center for children, or any permanently occupied human habitation other
than those used for industrial purposes.

          (2) Any new use of the land other than the use, modification, or expansion of an existing
industrial or manufacturing facility or complex.

     (C) Aerojet shall not construct any building or structure on any land described in Exhibit I-7
(“Exhibit I-7 land’) if the construction requires excavation, grading or removal of more than 10
cubic yards of soil, without first giving notice to and obtaining prior approval of DHS or,
alternatively, a determination of the Court favorable to Aerojet pursuant to Subparagraph 11(D).
The restrictions in this Subparagraph shall not apply to: (1) maintenance activities, (2)
activities taken within an existing building or structure to the extent that such activities are
necessary to change such building or structure to meet Aerojet’s operational needs, or (3)
activities undertaken pursuant to provisions of this Decree.

     (D) The notice required by Subparagraphs 11(B) and 11(C) shall be either by personal service
received or by registered mail postmarked, not less than 45 days prior to the beginning of the
proposed use or construction. Aerojet may proceed with the proposed use or construction and shall
be deemed to have obtained the approval of DRS unless, within 30 days following receipt of such
notice, the California Attorney General files an objection in the Court to the use or construction
on the ground that it may cause a significant hazard to present or future public health by reason
of discharges of hazardous substances occurring before the effective date of this

F-2

 

Decree, or that it will interfere with the performance of Aerojet’s obligations pursuant to
this Decree. Filing of the objection shall constitute a dispute to be resolved pursuant to
Paragraph 20 (Dispute Resolution) and the burden of proof shall be on Plaintiffs.

     (E) Aerojet will not grant any possessory interest in the land described in Exhibits I-1 or
I-5 (“Exhibit I-1 or I-5 land”) without first giving notice to the California Attorney General and
the United States, accompanied by a statement of the name of the grantee, the intended uses of the
land contemplated by the grantee, and Aerojet’s obligations if any, to be performed by the grantee.
The notice shall be either by personal service received, or by registered mail postmarked, not
less than sixty (60) days prior to the date of the proposed grant. Aerojet may proceed with the
proposed grant unless within thirty (30) days following the receipt of such notice, the United
States or the California Attorney General files an objection in the Court to the grant on the
ground that it would interfere with the performance of Aerojet’s obligations pursuant to this
Decree. Filing of an objection shall constitute a dispute to be resolved pursuant to Paragraph 20
(Dispute Resolution) and the burden of proof shall be on Plaintiffs.

     (F) In the event of a grant subject to the restrictions of this Paragraph, all of Aerojet’s
obligations pursuant to this Decree shall continue to be met by Aerojet, or, subject to Plaintiffs’
approval, by one or more grantees. Plaintiffs shall either approve or disapprove the assumption of
the obligation by a grantee within sixty (60) days of receipt of written notice seeking such
assumption. Any dispute regarding the assumption of any obligation shall be resolved pursuant to
Paragraph 20 (Dispute Resolution). The issue before the Court shall be whether the assumption by
the grantee would or would not have a material adverse effect on the fulfillment of the
requirements of the Decree proposed for assumption, including the adequacy of financial assurance.
A copy of Plaintiffs’ approval of the assumption or an order from the Court that

F-3

 

Plaintiffs approved the assumption will, when recorded, conclusively establish that the
obligation was assumed.

     (G) A grant of possessory interest in Exhibit I-1 or I-5 land shall contain a notice stating
that such land is a subject of this Decree and setting forth the caption of the case, case number,
and court having jurisdiction herein. No grant of Exhibit I—1 or I-5 land may be made by Aerojet
or its successors unless it contains a covenant that the grantee and any successor shall comply
with the restrictions of this Paragraph, that the grantee will not interfere with the performance
of obligations or exercise of rights pursuant to this Decree, and that the grantee will subject
itself to the jurisdiction of this Court in this action to enforce the restrictions of this
Paragraph. The covenant shall be in full force and effect until such time as Aerojet or a
successor records with the Recorder a waiver or waivers by Plaintiffs of the restrictions in a form
acceptable for recording, or an order of the Court eliminating the restrictions.

     (H) DHS may propose the addition of a portion of Exhibit I-1 or I-5 land to Exhibit I-5 or
Exhibit I-7 until the Phase II RI/FS report has been approved pursuant to Subparagraph 5(L). If
Plaintiffs and Aerojet cannot agree on any proposed addition, the dispute shall be resolved
pursuant to Paragraph 20 (Dispute Resolution) and the Plaintiffs shall have the burden of proving
the need of the addition. The State shall record with the Recorder a court order incorporating
additions to Exhibit I-6 or Exhibit I-7 land pursuant to this Subparagraph (H) within 60 (sixty)
days of issuance. Any such addition shall not be effective as to any subsequent grantee unless the
order has been timely recorded with the Recorder.

     (I) The Phase II RI/FS Report will address the appropriateness of deed restrictions.

     (J) This Paragraph imposes no restrictions on grants of possessory interest in land by Aerojet
made under leases, agreements or other conveyances existing as of the effective date of

F-4

 

this Decree, to the extent that the imposition of such restrictions would violate or change
the provisions of any such conveyance.

     (K) At any time, Aerojet or any grantee or successor may petition the Court for removal of the
restrictions stated in any or all subparagraphs of this Paragraph as to any or all lands, and any
such restriction shall be ordered removed unless the Court finds that, as to Exhibit I-6 or Exhibit
I-7 land, there is a need to retain such restriction to prevent a significant hazard to present or
future public health by reason of discharges of hazardous substances occurring before the effective
date of this Decree, or that as to Exhibit I-1 or I-5 land, there is need to retain it to prevent
interference with the performance of Aerojet’s obligations pursuant to this Decree.

     (L) Recording by Aerojet or a successor with the Recorder of an approval, order or notice
specified below in this Subparagraph (L) shall conclusively establish that Aerojet and any
subsequent grantee is free of any restrictions under the Order released by said approval, order or
notice:

          (1) Approval by DHS or Plaintiffs, as appropriate, of a grant, use, or construction;

          (2) An order of the Court permitting such grant, use, or construction;

          (3) A notice that Plaintiffs do not object to the grant, use or construction (notice of
non-objection), with proof of service of such notice on Plaintiffs, to which notice of
non-objection Plaintiffs do not, within 45 days of service, record in the office of the County
Recorder a notice that an objection had been timely made;

          (4) A notice that the obligations have terminated pursuant to Paragraph 26 of the Decree to
which notice Plaintiffs do not, within twenty (20) days of service, record a notice that such
obligations have not so terminated; or

F-5

 

          (5) A Court Order that the obligations have terminated pursuant to Paragraph 26 of the Decree.

     (M) As used in this Paragraph, “grantee” includes “lessee” and “grant” includes “lease.”

     (N) wherever it is provided in this Paragraph that notice shall be given to DHS, it shall be
sent to the person(s) on the most recent “Designation of person(s) to be notified regarding
restrictions on Aerojet use and transfer of land’ as provided to Aerojet by DHS.

Activities. To the extent required by Environmental Law, Lessor will also obtain any permits,
authorizations or approvals necessary to conduct the Remedial Activities, except such permits, if
any, as must under applicable Law be obtained by Lessee, or otherwise by an owner or tenant of the
Premises.

          2.2 Standard of Performance. Lessor’s Remediation Obligation shall be (A) performed
in accordance with: (i) any applicable Remedial Activity Plans, as approved by the PCD Agency; and
(ii) all applicable Environmental Law and Government Restrictions, and (B) performed in such a
manner as to minimize, to the extent commercially reasonably feasible and consistent with
Environmental Law and Government Restrictions, the impact on the use of the Premises and the
ongoing operations of Lessee. Notwithstanding the foregoing, Lessor’s obligation to indemnify
Lessee for any losses under the Lease with respect to any Pre-Term Environmental Liability shall be
limited (x) to the extent Lessee or its affiliates or any of their respective successors,
sublessees or assignees contributed to or exacerbated the condition or circumstance forming the
basis of such losses which are not caused by Lessee or its affiliates or any of their respective
successors, sublessees or and (y) to the most cost-effective, remedial alternative that is
protective of human health and the environment and is consistent with and meets the requirements of
any applicable Environmental Law and any Governmental Authority based upon the use of the Premises
as industrial property.

          2.3 Performance and Planning of Remedial Activities.

               (a) Information to be Provided by Lessor to Lessee. Lessor shall provide to Lessee in
a timely fashion (to the extent practicable), a copy of: (i) any documents submitted to any PCD
Agency regarding any Remedial Activities relating to the Premises to be performed by or on behalf
of Lessor, and (ii) analytical results of any environmental sampling conducted on the Premises by
or on behalf of Lessor.

               (b) Lessee Opportunity to Comment. Lessor shall provide Lessee with a reasonable
opportunity to timely review and comment upon, prior to their submission to the PCD Agencies, any
report, plan, proposal or other document that: (i) proposes the performance of any Remedial
Activities that could disrupt or interfere with the then current day to day operations of Lessee or
any permitted sublessee; (ii) involves the construction on the Demised Land of any aboveground
remedial fixtures (other than repair and maintenance of any such fixtures or equipment as are
present at the Premises as of the Term Commencement Date); (iii) proposes any remedy or closure on
the Demised Land that allows Hazardous Substances to

G-2

 

remain on the Demised Land after remediation has been completed; or (iv) involves the setting of
health and safety standards with respect to exposure to Hazardous Substances at the Premises.

               (c) Lessee Participation. To the extent permitted by the PCD Agency or other
Governmental Authority, Lessee, or its designated representative, shall have the right, but not the
obligation, to be present and at any meeting with, or hearing before, any PCD Agency or other
Governmental Authority regarding any proposed modification to the Partial Consent Decree, proposed
Remedial Activities, or proposed Remedial Activity Plans described above. Lessor and Lessee
further agree to use their respective commercially reasonable efforts to confer in good faith in
advance (if practicable) of any such meeting or hearing with respect to any matters to be addressed
at such meeting or hearing and for the purpose of resolving such matter to their mutual
satisfaction and presenting a unified position to the Governmental Authority or PCD Agency, to the
extent consistent with the respective positions of the parties. If the parties cannot reach
agreement regarding a unified position after such consultation or Lessee reasonably determines that
any proposed Remedial Activities or Remedial Activity Plans will have an adverse impact on the use
of, or operations at, the Demised Land, then Lessee shall have the right to make objections to such
proposals to the relevant Governmental Authority or PCD Agency, subject to the standards of
performance and use of the Demised Land as industrial in accordance with Section 2.1 of this
Exhibit “G”.

               (d) Consultation With Lessee. Lessor agrees to consult with Lessee regarding any
proposed Remedial Activities or proposed Remedial Activity Plans affecting the Demised Land.
Lessor and Lessee agree to use their respective commercially reasonable efforts to reach agreement
on such Remedial Activities or Remedial Activity Plans. The parties also agree that in the event
they cannot reach agreement, Lessor may submit to the PCD Agency or Governmental Authority its
proposed Remedial Activity Plans, as required to meet any deadline, and Lessor may also proceed
with implementation of any aspects of such Remedial Activities or Remedial Activity Plans. If the
parties cannot reach agreement after such consultation and Lessee reasonably determines that any
proposed Remedial Activities or Remedial Activity Plans will have an adverse impact on the use of,
or operations at, the Demised Land, then Lessee shall have the right to make objections to such
proposals to the relevant Governmental Authority or PCD Agency, subject to the standards of
performance and use of the Demised Land as industrial in accordance with Section 2.1 of this
Exhibit “G”.

               (e) Performance of the Remedial Activities. Following approval of any Remedial
Activity Plans by the applicable PCD Agency or Governmental Authority, Lessor may proceed with the
implementation of the Remedial Activities in accordance with the Remedial Activity Plans and the
Lease in such a manner as to minimize, to the extent commercially reasonably feasible the impact on
the use of the Premises and the ongoing operations of Lessee subject to the standards of
performance and use of the Demised Land as industrial in accordance with Section 2.1 of this
Exhibit “G”.

               (f) Lessee’s Assistance. Lessee shall use its commercially reasonable efforts to
assist Lessor in the development, approval, and implementation of Remedial Activity Plans in
accordance with applicable Law, including applicable Environmental Law and the Partial Consent
Decree. Notwithstanding anything contained in the Lease or this Exhibit “G” to

G-3

 

the contrary, (i) Lessee shall provide full cooperation, assistance, and access to the Premises to
the PCD Agencies as to their oversight of or their implementation of Remedial Action (including the
cooperation and access necessary for the installation, integrity, operation, and maintenance of any
complete or partial response action or natural resource restoration at the Premises); and (ii)
Lessee shall not impede the effectiveness or integrity of any institutional control employed in
connection with a Remedial Action.

          2.4 Safety; No Further Investigation.

               (a) Lessor shall be responsible for actions of its employees, consultants, contractors, and
subcontractors engaged in the performance of Remedial Activities. Except in case of emergency and
to the extent that prior notice of such policies is given to Lessor, Lessor also will require its
employees, consultants, contractors, and subcontractors engaged in performance of Remedial
Activities on behalf of Lessor to observe any health, safety and environmental and site security
policies established by Lessee, or by any other authorized tenant, for third-party contractors and
other non- employees who perform work or services at the Premises. Lessee shall have the right to
require that a contractor, subcontractor or other representative of Lessor discontinue any Remedial
Activities to the extent such activities pose an imminent risk to property, health, safety or the
environment. In such instance, Lessee shall immediately notify Lessor by telephone that it has
taken such action.

               (b) With respect to the Premises on and after the Term Commencement Date, Lessee, on behalf of
itself and its affiliates and its successors and assigns, agrees not to, and agrees not to enter
into any agreement that would permit its successors or assigns or the successors or assigns of its
affiliates to, take any voluntary action, including any sampling of the soil or groundwater, or to
initiate or encourage any action by any third party, including any Governmental Authority or third
party, which could reasonably be expected to lead to a claim or demand by such Governmental
Authority or third party under any Environmental Law; provided that if any Law, including any
Environmental Law, with respect to the Premises, or the defense of any third party claim against
Lessee, requires Lessee or any of its affiliates, successors or assigns to investigate, take
action, initiate or encourage any such action, Lessee will promptly notify Lessor of such
requirement and the content and timing of any action that Lessee (or its affiliates, successors or
assigns) proposes to take, and the parties hereto shall consult with each other regarding the
satisfaction of such requirement. Notwithstanding anything to the contrary contained herein,
neither Lessor nor any of its affiliates shall have any liability for any Pre-Term Environmental
Liabilities to the extent arising out of or in connection with any action (whether the taking of
soil or groundwater samples or otherwise) prohibited by this Section 2.4(b), whether by Lessee or
any other person, including any subsequent owner or operator of any part of the Acquired Business.

          2.5 Compliance with Governmental Restrictions. In addition to all other covenants and
conditions set forth in the Lease with respect to Governmental Restrictions, Lessor and Lessee
(which includes their respective successors as set forth in Section 15.7 of the Lease) agree as
follows:

               (a) Lessee will not construct any new building or other Improvement on the Demised Land if
such construction would involve excavation, grading, or removal of

more than ten (10) cubic yards of soil without first providing 60 days’ advance written notice
to Lessor so that approval by the PCD Agencies can be requested, as required by any Governmental
Restrictions, and no such excavation, grading, or removal shall occur without the prior issuance of
written approval from the PCD Agencies or such agencies to the extent required by Governmental
Restrictions. Lessee shall promptly reimburse Lessor for all reasonable costs and expenses
incurred by any of them in connection with Lessee’s seeking such approval, including, but not
limited to, attorneys’ fees and expert and consultant fees;

               (b) Pursuant to paragraph 11(F) of the Partial Consent Decree, as well as pursuant to other
Governmental Restrictions, and subject to Lessee’s rights provided for in the Lease, Lessor shall
continue, at all times during the Term, to perform, and hereby reserves all interests, access
rights, and powers as may be necessary to perform, Lessor’s obligations under the Partial Consent
Decree, as well as under other Governmental Restrictions, with respect to the Aerojet Site and
every part thereof, including, but not limited to, the Demised Land;

               (c) The Lease is, and all of Lessee’s rights and powers under the Lease are, subject and
subordinate to the Partial Consent Decree and the Governmental Restrictions;

               (d) Lessee will comply with the restrictions contained in paragraph 11 of the Partial Consent
Decree (see Exhibit “F” attached hereto) and with all additional or different conditions contained
in other Governmental Restrictions, provided that Lessor shall have provided to Lessee copies of
any and such conditions imposed after the Term Commencement Date upon reasonable notice to Lessee
to enable Lessee compliance as set forth herein;

               (e) Lessee will not interfere with the performance of obligations or the exercise of rights by
Lessor regarding the Demised Land and/or the Aerojet Site done under, or pursuant to, or as
required by, the Partial Consent Decree or any other Governmental Restrictions, including, but not
limited to, performance of the Remedial Activities, and Lessor shall, in connection with such
performance of obligations or exercise of rights, use commercially reasonable efforts not to
materially interfere with Lessee’s uses of the Premises;

               (f) Lessee will subject itself to the jurisdiction of United States District Court, Eastern
District, California overseeing the Partial Consent Decree in order to enforce the restrictions of
paragraph 11 of the Partial Consent Decree;

               (g) Lessee agrees to give to Lessor, within twenty-four (24) hours (or as soon as reasonably
possible thereafter), verbal and written notice of any spill or Release of any Hazardous Substance
onto the Premises or the Aerojet Site or any part of either;

               (h) Lessee will not communicate with the PCD Agencies or any of them as to contamination
conditions that are the subject of the PCD, except as coordinated with, and approved by, Lessor,
and Lessee shall first provide notifications required by the Lease to Lessor only and work under
Lessor’s leadership in any approach to, and all communications with, the PCD Agencies; and

G-5

 

               (i) If and whenever any of the Governmental Restrictions shall require Lessor to make any
change or addition to the provisions of the Lease to accommodate or comply with any Governmental
Restrictions, Lessor and Lessee shall promptly execute and deliver an appropriate amendment to the
Lease in compliance therewith; provided that such amendment does not materially and adversely alter
or supersede any of Lessee’s rights hereunder.

          2.6 Construction Activities and Repair Activities.

               (a) In addition to the provisions of Section 8 of the Lease, the provisions of this Section
2.6 of Exhibit “G” shall apply to any construction or repair activity by Lessee or by any
authorized tenant that involves disturbance or invasion of any Hazardous Substance that is part of
Lessor’s Remediation Obligation.

               (b) Subject to the restrictions set forth in Section 2.4 of this Exhibit “G”, if testing
conducted in the proposed construction or repair area before initiation of the construction or the
repair activity demonstrates that the proposed construction or repair area contains a Hazardous
Substance in the soil or subsurface that is part of Lessor’s Remediation Obligation and, further,
if Lessee provides notice to Lessor of such Hazardous Substance and of said proposed construction
or repair activity in the manner provided in the Notice provision of the Lease, then Lessor and
Lessee shall consult with respect to their to and will use reasonable commercial efforts to
identify a different site within the Demised Premises suitable for such construction or repair
which would be consistent with Law, Government Restrictions and the terms of the Lease. If no such
alternative site is practicable, consistent with any requirements under any Governmental
Restriction, Lessor shall (i) promptly and diligently conduct Lessor’s Remediation Obligation of
such Hazardous Substance identified by the testing to the extent required by the standard of
performance set out above and as required by the PCD and Governmental Restrictions. In the event
Lessee anticipates incurring construction costs, Lessee shall provide Lessor reasonable advance
notice before the costs are incurred.

               (c) In the event, as a result of any construction or repair activity, any of the then existing
above ground or underground remediation systems (including, without limitation, pump and treat
equipment, underground piping, monitoring or extraction wells, carbon absorption systems and the
like) are damaged or destroyed, or are required to otherwise be relocated (with such relocation
being at Lessor’s control and in accordance with all Law and Governmental Restrictions) Lessee
shall reimburse Lessor for all costs associated with such damage, destruction or removal.

ARTICLE 3.

REGULATORY PROCESSES

          4.1 Communications. In the event of any written notices or other written
communication or action by a Governmental Authority or PCD Agency relating to or affecting the
Remedial Activities or any Remedial Activity Plans, or any communication from the public evidencing
any concerns about the Remedial Activities or Hazardous Substances on our about the Premises, the
party receiving such notice, communication, or action shall provide a copy to the other party in a
timely fashion. Lessor shall be responsible for all contacts and communications with Governmental
Authorities in connection with Lessor’s Remediation Obligation and any other matters arising under
the Lease which are the obligation of Lessor. Lessor also agrees to promptly reimburse Lessee for
any reasonable “out-of-pocket” costs (excluding any internal Lessee charges for administration,
management or supervision or other internal charges) incurred by Lessee in providing support to
Lessor to respond to such notice, communication, or action.

          4.2 Regular Meetings. Lessor and Lessee shall attend regular meetings with one
another to discuss the status of Lessor’s Remediation Obligation, including without limitation, the
development, approval, and implementation of Remedial Activity Plans, and to coordinate regarding
Lessor’s Remedial Activities under the Lease.

          4.3 Lessor Project Managers/Lessee Liaison. For consultation and coordination
regarding Lessor’s Remedial Activities under the Lease, and to manage their respective activities
and responsibilities under the Lease, Lessor shall designate a Project Manager and Lessee shall
designate a Lessee Liaison for the Premises. Designation of a Project Manager and of a Lessee
Liaison shall be by notice as provided in the Lease. Lessor may replace any of its Project
Managers, and Lessee may replace any of its Lessee Liaisons, by providing the same notice.

          4.4 Inspection. Subject to applicable Law and Governmental Restrictions, Lessee shall
have the right to inspect and observe the Remedial Activities performed by or on behalf of Lessor,
at reasonable times and after reasonable prior written notice to Lessor. Inspection or failure to
inspect by Lessee shall not constitute a waiver of any provision of the Lease, or of any of
Lessee’s rights hereunder. However, Lessee’s right or exercise of inspection shall not extend to
or include any right or authority to supervise or direct any of Lessor’s employees, consultants,
contractors or subcontractors in their performance of any Remedial Activities. Further, such
inspections must not negatively impact Lessee’s operations.

          4.5 Notifications. Lessor, Lessee, and any authorized tenant shall notify the other
parties within twenty-four (24) hours (or as soon as reasonably possible thereafter) following the
occurrence of any Release that causes contamination to soil or groundwater on the Premises or
otherwise: (i) requires investigation, monitoring, remediation or removal under the Environmental
Law; (ii) may adversely affect any Remedial Activities or Remedial Activity Plans; (iii) is
reported to such party’s insurance carrier; or (iv) is reported to any Governmental Authority under

any Premises by any Governmental Authority or PCD Agency in connection with the Remedial Activities
or Lessor’s Remediation Obligation. Lessee also agrees to give Lessor prompt advance notice (if
and to the extent Lessee has knowledge of the same) of any inspection to be performed on any
Premises by any Governmental Authority with jurisdiction over the Remedial Activities or Lessor’s
Remediation Obligation.

ARTICLE 5.

HAZARDOUS SUBSTANCES AND INDEMNITY

          5.1 Hazardous Substances. Without limiting the generality of the foregoing, Lessee’s
use and occupancy of the Premises or any portion thereof shall at all times be in strict compliance
with any and all federal, state and local statutes, Law, rules, regulations, orders, ordinances and
standards, as they may now or hereafter exist, relating in any way to the protection of the
environment, including, without limitation, the Comprehensive Environmental Response, Compensation
and Liability Act, as amended, 42 U.S.C. Sections 9601, et seq. (“CERCLA”) the Resource
Conservation and Recovery Act, as amended, 42 U.S.C. Sections 6901, et seq. (“RCRA”), the Toxic
Substances Control Act, as amended, 15 U.S.C. Sections 2601, et seq., the Clean Water Act, as
amended, 33 U.S.C. Sections 1251, et seq., the Clean Air Act, as amended, 42 U.S.C. Sections 7401,
et seq., and analogous state statutes (collectively, “Environmental Statutes”) and the following:

               (a) In the event Lessee shall, on, at or about the Premises, use, store, or generate or permit
or suffer the use, storage, or generation of any Hazardous Substance, then Lessee, at its sole cost
and expense, shall comply with all applicable Environmental Statutes, rules, regulations, orders,
and decrees relating to the same. Lessee shall not engage in operations that involve the disposal
on or about the Premises of any Hazardous Substance. Lessee shall be solely responsible for
obtaining, at its own cost and expense, any environmental permits required for its operation under
the Lease or on the Premises.

               (b) In the event of any Release that occurs in connection with Lessee’s activities or the
activities of any of its employees, agents, representatives, lessees, sublessees, licensees or
contractors on the Premises or threat of a Release occurring in connection with Lessee’s activities
or the activities of any of its employees, agents, representatives, lessees, sublessees, licensees
or contractors on or about the Premises, Lessee shall immediately (and in no event later than
within twenty-four (24) hours to the extent reasonably possible) notify the Lessor verbally and in
writing thereof, so that Lessor may provide such notices as may be required by the Partial Consent
Decree. The existence of the Partial Consent Decree may affect the manner in which a response to a
Release or to a threat of Release of any Hazardous Substance is undertaken and whether such
response should be undertaken by Lessor. In the event of a Release or a threat of Release of any
Hazardous Substance, Lessee shall take such steps as are required by Law and shall cooperate with
Lessor (including, but not limited to, Lessee’s cooperation with Lessor to the extent Lessor must
take action under the Partial Consent Decree) to respond to such condition. To the extent such
steps can lawfully be taken by Lessor,

G-9

 

rather than Lessee, Lessee shall defer to Lessor’s election, if any, to assume the lead in
taking such steps, so long as Lessee’s operations will not be negatively impacted. Any election by
Lessor to take such steps shall not constitute a waiver or irreversible election of any rights or
remedies. Regardless whether Lessor or Lessee is required to, or does, undertake such action,
Lessee agrees to defend, pay and to indemnify and protect Lessor (to the extent that the Release
occurred after the Term Commencement Date, or to the extent that is it is not a Pre-Term
Environmental Liability) from and against all costs, expenses, and liabilities, including, but not
limited to, attorneys’ fees, expert and consultant fees, fines, and penalties, as and when incurred
by Lessor with respect to such Release or threat of Release of any Hazardous Substance and any
response thereto undertaken by the other.

               (c) Lessee shall, at all times, indemnify, defend, protect, and hold harmless Lessor and any
lender of Lessor, including, with respect to Lessor, any mortgage holder, against and from any and
all claims, liens, suits, actions, debts, damages, costs, losses, liabilities, obligations,
judgments, and expenses (including, without limitation, court costs, expert and consultant fees,
attorneys’ fees, including those incurred on appeal, fines, penalties, and damage to, or loss
suffered by, Lessor, or the Aerojet Site or any portion thereof), of any nature whatsoever, arising
from or relating to (i) Lessee’s failure to perform the obligations required under this Section
5.1; (ii) a Release of any Hazardous Substance that occurs in connection with Lessee’s activities
or the activities of any of its employees, agents, representatives, lessees, sublessees, licensees
or contractors to the extent that the Release occurred after the Term Commencement Date, or to the
extent that is it is not a Pre-Term Environmental Liability, on or about the Premises or on or
about the Aerojet Site, including, but not limited to, the Roadways; (iii) the threat of a Release
of any Hazardous Substance occurring in connection with Lessee’s activities or the activities of
any of its employees, agents, representatives, lessees, sublessees, licensees or contractors on or
about the Premises or on or about the Aerojet Site, including, but not limited to, the Roadways to
the extent that the threatened Release occurred after the Term Commencement Date, or to the extent
that is it is not a Pre-Term Environmental Liability; or (iv) the presence of any Hazardous
Substance at the Premises which is not a Pre-Term Environmental Liability. Lessee’s obligations
under the Lease shall arise whether or not any Governmental Authority or individual has taken or
threatened any action in connection with the presence of any Hazardous Substance.

               (d) Nothing in this Section 5.1 shall be construed to make Lessee liable in any way for any
Release or the presence of any Hazardous Substance affecting the Premises occurring prior to the
Term Commencement Date, or anyone claiming by, through or under Lessee, or anyone by, through or
under whom Lessee claims, except to the extent any of such parties or their agents, employees,
representatives, licensees, invitees, contractors or the like caused the Release. By making the
covenants contained in this Section 5.1, Lessee does not undertake any obligation with respect to
any environmental condition that is not attributable to Lessee’s activities or the activities of
one or more of Lessee’s employees, agents, representatives, sublessees, licensees or contractors on
or about the Premises, including, but not limited to, the contamination of groundwater underlying
the Demised Land as is the subject of the Partial Consent Decree.

G-10

 

               (e) Lessee shall provide all relevant information regarding such Hazardous Substances,
including, without limitation, its Material Safety Data Sheet (MSDS), to (i) Lessor, and (ii)
emergency personnel such as fireman and hazardous materials teams immediately upon the occurrence
of a Release, fire, casualty or other occurrence in, on or about the Premises.

               (f) Lessee agrees to permit Lessor and its authorized representatives to enter, inspect and
assess the Premises and Lessee’s records at reasonable times for the purpose of determining
Lessee’s compliance with the provisions of this Section 5.1. Such inspections and assessments may
include obtaining samples and performing tests of building materials, soil, surface water,
groundwater or other media. Any activity taken by Lessor pursuant to this Section 5.1(f) shall
minimize the negative impact on Lessee’s operations.

               (g) Upon the expiration or termination of the Lease, Lessee agrees to pay, defend, protect,
and indemnify Lessor from and against all costs, expenses, and liabilities associated with the
investigation, reconnaissance, remediation, removal, and disposal of any and all Hazardous
Substances that: (i) are not otherwise Pre-Term Environmental Liabilities; or (ii) are not the
result of Lessor’s activities or the activities of any employee, agents, representatives, lessees,
licensees or contractors of Lessor in order to return the Premises to the condition existing as of
the Term Commencement Date and to save Lessor harmless therefrom.

               (h) Lessor shall, at all times, indemnify, defend, protect, and hold harmless Lessee (and its
permitted subtenants, assignees, successors and assigns) and any lender of such parties including
any mortgage holder, against and from any and all claims, liens, suits, actions, debts, damages,
costs, losses, liabilities, obligations, judgments, and expenses (including, without limitation,
court costs, expert and consultant fees, attorneys’ fees, including those incurred on appeal,
fines, penalties, and damage to, or loss suffered by, Lessee, or the Demised Land), of any nature
whatsoever, arising from or relating to Pre-Term Environmental Liabilities.

               (i) This entire Section 5.1 shall survive termination or the expiration of the Lease.

reference purposes as of ___, 20___, is made by and between Aerojet-General
Corporation, an Ohio corporation (“ Seller ”), and AMPAC Fine Chemicals
LLC, a California limited liability company (“ Buyer ”). This Agreement shall not
be effective until executed by both Buyer and Seller, and the date on which this Agreement is
executed by Buyer or Seller, whichever is later, as indicated on the signature page hereto, shall
be referred to herein as the “ Effective Date .”

Recitals

     A. Seller, as Lessor, and Buyer, as Lessee, previously entered into that certain Ground Lease
(the “ Ground Lease ”), dated for reference purposes, as of ___, 2005 pursuant to
which Buyer currently occupies that certain real property containing approximately two hundred
forty-one (241) acres located in the City of Sacramento, County of Sacramento, State of California
as more particularly described in Schedule 1.1 hereto (the “ Land ”).

     B. The terms and provisions of the Ground Lease contain an option to purchase the Land and
Seller and Buyer have executed this Agreement in accordance with Buyer’s proper exercise of such
option.

     C. For purposes of this Agreement, “Purchase Agreement” shall mean that certain asset purchase
agreement by and among American Pacific Corporation, Aerojet Fine Chemicals LLC, and Seller dated
as of July 12, 2005, as amended.

     Now, therefore, in consideration of the mutual promises and covenants contained
herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:

1. Purchase and Sale

     Seller hereby agrees to sell to Buyer, and Buyer hereby agrees to purchase from Seller,
subject to the terms, covenants and conditions set forth herein, all of the following property:

     (a) the Land;

     (b) Any buildings, structures and improvements erected or located on the Land, that are not
already the property of Buyer, including without limitation the Lessor’s Improvements (as defined
in the Ground Lease) (collectively, the “ Improvements ,” and together with the Land,
collectively, the “ Premises ”);

     (c) All of Seller’s right, title and interest, if any, in and to any rights and appurtenances
pertaining to the Land, including minerals, oil and gas rights, air, solar, development rights,
easements, and rights of ingress and egress (the “ Appurtenant Rights ”); and

     (d) The Easements (as defined in Section 6 below).

J–6

 

     The Premises, Appurtenant Rights, and the Easements are herein collectively referred to as the
“ Property .”

2. Purchase Price; Deposit; Escrow

     (a) The purchase price (“ Purchase Price ”) for the Property shall be One Thousand
Dollars ($1,000.00), subject to adjustment for prorations and credits as provided in Section 6
below.

     (b) Within two (2) business days following the Effective Date, Buyer shall deposit in escrow
with First American Title Insurance Company, 3721 Douglas Blvd., Suite 151, Roseville, California
95661, Attention: Carolyn Hunt (the “ Escrow Holder ”), as an initial deposit hereunder,
the amount of the Purchase Price (the “ Initial Deposit ”). The Initial Deposit,
together with all interest accrued thereon, are referred to herein as the “ Deposit .”
The Deposit shall at all times before the Closing be invested in an interest-bearing account
approved by Buyer in writing. Buyer shall provide the Escrow Holder with its taxpayer
identification number, and all interest earned on the Deposit shall be reported to the appropriate
tax authorities using Buyer’s taxpayer identification number. At the Closing, the Deposit shall be

     (c) Seller acknowledges and agrees that Buyer may be required to withhold a portion of the
Purchase Price pursuant to Section 1445 of the United States Internal Revenue Code (the
“ Federal Code ”) or Sections 18805 and 26131 of the California Revenue and Taxation Code
(the “ California Code ”). (Sections 18805 and 26131 of the California Code, together
with any regulations now or hereafter promulgated thereunder, are sometimes collectively referred
to below as the “ California Withholding Provisions ,” and Section 1445 of the Federal
Code, together with any regulations now or hereafter promulgated thereunder, are sometimes
collectively referred to below as the “ Federal Withholding Provisions .”) Any amount
properly so withheld by Buyer in accordance with the provisions of Section 5.2 below shall be
deemed to have been paid by Buyer as part of the Purchase Price, and Seller’s obligation to
consummate the transactions contemplated herein shall not be excused, reduced, terminated or
otherwise affected thereby.

     (d) Within two (2) business days following the Effective Date, Buyer shall deliver a copy of
this Agreement to the Escrow Holder. This Agreement shall serve as the initial escrow
instructions. Counsel for Buyer and Seller are hereby authorized to execute any further escrow
instructions necessary or desirable, and consistent with the terms hereof, in connection with the
escrow established for this transaction by the Escrow Holder (the “ Escrow ”). Escrow
Holder shall be the “ Reporting Person ” pursuant to Internal Revenue Code Section
6045(e) with respect to the transaction contemplated by this Agreement.

hereof will (i) violate or conflict, in any material respect, with any statute, regulation, rule,
injunction, judgment, order, decree, ruling, charge or other restrictions of any government,
governmental agency or court to which Seller is subject, or (ii) to Seller’s knowledge, result in
any material breach or the termination of any lease, agreement or other instrument or obligation to
which Seller is a party or by which any of the Property may be subject, or cause a lien or other
encumbrance to attach to any of the Property.

     (d) All material consents required from any governmental authority or third party in
connection with the execution and delivery of this Agreement by Seller or the consummation by

     (h) Other than as may relate to improvements owned or leased by Buyer for which Seller makes

governmental investigation, administrative proceeding, condemnation or sale in lieu thereof, or of
any violations of any zoning, building code, fire safety or health codes or regulations with
respect to any portion of the Property, except as noted on Schedule 3.2(h) attached
hereto. Seller further covenants that if Seller should receive any such notice prior to the
Closing Date, Seller will provide Buyer with copies of the notice promptly following the receipt
thereof by Seller.

     (i) Other than the Ground Lease, Seller has not, subsequent to ___, 2005, granted any
party the right to possession of any portion of the Land.

     (j) Seller has not granted any party other than Buyer any right to purchase the Property.

     3.3 Seller’s Knowledge

     Whenever the term “to Seller’s knowledge” is used in this Agreement or in any representations
and warranties given to Buyer at the Closing, such knowledge shall be the actual knowledge of
___, whom Seller represents to be the person with knowledge of the Property.

     3.4 Survival

     All representations and warranties of Seller set forth in Section 3.2 are made as of the
Effective Date. In addition, as of Closing Date, Seller shall provide Buyer with a certification
regarding the accuracy of such representations and warranties as of such date, including any
exceptions or qualifications thereto as of such date (“ Seller’s Closing
Certification ”). The representations and warranties of Seller set forth in Section 3.2 shall
survive the Closing of the transaction contemplated in this Agreement and the delivery of the Grant
Deed from Seller to Buyer for a period of one (1) year from and after the Closing Date (the
“ Survival Period ”); provided, however, that Buyer must give Seller written notice of
any claim Buyer may have against Seller for breach of any such representations and warranties set
forth in Section 3.2, prior to the expiration of the Survival Period. Any such claim which Buyer
may have which is not so asserted prior to the expiration of the Survival Period shall not be valid

     3.5 Representations and Warranties of Buyer

     (a) Buyer is a California limited liability company, duly organized, validly existing and in
good standing under the laws of California.

J–9

 

     (b) Buyer has the power and authority to enter into this Agreement and to execute and deliver
the other documents referred to herein and to perform hereunder and thereunder on behalf of Buyer.
This Agreement has been duly authorized, executed and delivered by Buyer.

     (c) Neither the execution and delivery of this Agreement, the consummation of the transactions
contemplated by this Agreement, nor the compliance with the terms and conditions hereof will
violate, in any material respect, any statute, regulation, rule, injunction, judgment, order,
decree, ruling, charge or other restrictions of any government, governmental agency or court to
which Buyer is subject.

     (d) Buyer is not required to obtain the consent or approval of any government agency,
department or other government body or any third party to enter into this Agreement or if required,
any such required consents or approvals have been obtained.

     (e) All material consents required from any governmental authority or third party in

proceedings in bankruptcy, existing, pending or, to Buyer’s knowledge, threatened against Buyer.

     3.6 Survival

     All representations and warranties of Buyer set forth in Section 3.5 are made as of the
Effective Date. In addition, as of Closing Date, Buyer shall provide Seller with a certification
regarding the accuracy of such representations and warranties as of such date, including any
exceptions or qualifications thereto as of such date (“ Buyer’s Closing Certification ”).
If the exceptions or qualifications to such representations and warranties as of the Closing Date
are material and are not acceptable to Seller in its sole discretion, Seller may refuse to
consummate this transaction, but Buyer shall have no liability to Seller as a result of such
qualification and exceptions; provided that if Buyer shall assign its interest in this Agreement,
Buyer shall be entitled to modify the representation set forth in Section 3.5(a) to reflect the
status of the assignee of Buyer, and Seller shall not be entitled to terminate this Agreement as a
result thereof. The representations and warranties of Buyer set forth in Section 3.5, subject to
any exception and qualification set forth on Buyer’s Closing Certification, shall survive the
Closing of the transaction contemplated in this Agreement and the delivery of the Grant Deed from
Seller to Buyer for the Survival Period; provided, however, that Seller must give Buyer written
notice of any claim Seller may have against Buyer for breach of any such representations and
warranties set forth in Section 3.5 (as modified by any exceptions and qualifications set forth on
Buyer’s Closing Certification), prior to the expiration of the Survival Period. Any such claim
which Seller may have which is not so asserted prior to the expiration of the Survival Period shall
not be valid or effective, and Buyer shall have no liability with respect thereto.

J–10

 

4. Conditions to Closing

     4.1 Conditions to Seller’s Obligations to Close

     The obligation of Seller to consummate the sale of the Property as contemplated by this
Agreement is subject to the fulfillment of each of the following conditions (in addition to such
other items as are set forth elsewhere in this Agreement as conditions to Seller’s obligations to
close), any or all of which may be waived in whole or in part by Seller to the extent permitted by
applicable law:

     (a) Deposit of Funds. Buyer shall have deposited into Escrow the Purchase Price, subject to
adjustment for any prorations and credits provided hereunder, and all other monies required to be
deposited by Buyer hereunder.

     (b) Delivery of Closing Documents. Buyer shall have deposited into escrow, for delivery to
Seller upon the Closing, all instruments and documents to be delivered by Buyer to Seller at the
Closing under the provisions of this Agreement.

     (c) Payment of Note and Earn Out. Buyer shall have paid in full to Seller (as defined in the
Purchase Agreement) (i) the full principal amount to Seller under the Note (as defined in the
Purchase Agreement) and any interest owed thereon, and (ii) any and all monies (including interest)
under the Earn Out (as defined in the Purchase Agreement).

     (d) Buyer’s Compliance. Buyer shall have performed and satisfied in all material respects the
covenants and obligations of Buyer under this Agreement to the extent such covenants and
obligations are to be performed or satisfied as of the Closing Date.

     The conditions set forth in this Section 4.1 are solely for the benefit of Seller and may be waived
only by Seller. Seller shall at all times have the right to waive any condition. Any such waiver
or waivers shall be in writing and shall be delivered to Buyer and Escrow Holder. If any of the
conditions in this Section 4.1 is not satisfied or has not been so waived by Seller prior to the
Closing Date, Seller shall deliver written notice to Buyer describing the condition that has not
been satisfied or waived, and if such condition remains unsatisfied as of the Closing Date, then
Seller shall have the right to terminate this Agreement and the Escrow by written notice to Buyer
and Escrow Holder. If Seller terminates this Agreement in accordance with the foregoing, the
Deposit shall be returned to Buyer, all documents deposited into Escrow shall be returned to the
party depositing such documents, and neither party shall have any further rights or obligations
under this Agreement, except for those rights or obligations which expressly survive the
termination of this Agreement; provided, however, if the failure of such condition also constitutes
a default of Buyer under this Agreement, then provided Seller is not in default under this
Agreement, the provisions of Section 9(a) shall apply, and the Deposit shall be paid to Seller as
liquidated damages, rather than being returned to Buyer.

     4.2 Conditions to Buyer’s Obligations to Close

     Notwithstanding anything in this Agreement to the contrary, Buyer shall have the option, to be
exercised in writing at any time prior to the Closing, to terminate this Agreement, following which
the Deposit shall be returned to Buyer, and neither party shall have any further liability or

J–11

 

obligation to the other hereunder, except for provisions of this Agreement which expressly
state that they shall survive the termination of this Agreement.

5. Closing and Transfer of Title

     5.1 Closing Date

     Provided that all of the conditions precedent to the Closing have been satisfied or waived,
the Closing shall be held, and delivery of all items to be made at the Closing under the terms of
this Agreement shall be made, at the offices of the Escrow Holder on a date to be designated by
Buyer in its Purchase Notice (as defined in the Ground Lease), but not fewer than six (6) months or
more than twelve (12) months after delivery of the Purchase Notice, or such earlier date and time
as Buyer and Seller may mutually agree upon in writing (the “ Closing Date ”). At the
Closing, Seller shall convey, by way of a Deed, fee simple absolute title to the Property, subject
only to the Permitted Exceptions.

     5.2 Seller’s Deliveries

     At the Closing, or at such later date as may be indicated below for any specific item, Seller
shall deliver or cause to be delivered to Buyer through the Escrow or otherwise, each of the
following instruments and documents, duly executed and acknowledged by Seller, as appropriate:

     (a) Grant Deed in the form attached hereto as Exhibit A (the “ Deed ”),
subject only to the Permitted Exceptions.

     (b) If requested by Buyer, a commercially reasonable form of lease termination (the
“ Lease Termination Agreement ”), provided that the effectiveness of the Lease
Termination Agreement shall be expressly conditioned upon the occurrence of the Closing.

     (c) An environmental matters agreement in the form attached hereto as Exhibit F
(the “ Environmental Agreement ”).

     (d) Seller’s Closing Certification, in the form attached hereto as Exhibit B , to
be provided by Seller pursuant to Section 3.4 above.

     (e) Any required real estate transfer tax declarations or any other similar documentation
required to evidence the payment of any tax imposed by the state, county and city on the
transaction contemplated hereby.

     (f) An affidavit pursuant to Section 1445(b)(2) of the Federal Code, and on which Buyer is
entitled to rely, from Seller that it is not a “foreign person” within the meaning of Section
1445(f)(3) of the Federal Code, in the form attached hereto as Exhibit C attached
hereto (the “ FIRPTA Affidavit ”). If Seller fails to deliver such FIRPTA Affidavit,
Buyer shall not be excused from its obligation to consummate the transactions contemplated herein,
but rather may deduct and withhold from the Purchase Price payable to Seller an amount equal to ten
percent (10%) of the “amount realized on the disposition” of any “United States real property
interest” in connection with the transactions contemplated herein, all as defined and required by
the Federal

J–12

 

Withholding Provisions. Any amount so withheld shall be deemed to have been paid by Buyer as
a part of the Purchase Price. Should Seller deliver a withholding certificate issued by the IRS
pursuant to the Federal Withholding Provisions which permits Buyer to withhold an amount less than
10% of the amount realized on the disposition, Buyer shall withhold such lesser amount, and the
amount so withheld shall be deemed to have been paid by Buyer as part of the Purchase Price.

     (g) Either (i) a properly executed certificate (herein, a “ Qualifying
Certificate ”) under Section 18662 of the California Revenue and Taxation Code
(“ CALFIRPTA ”) certifying that Seller is not an “individual” seller under CALFIRPTA and
either (A) has a permanent place of business in California, or (B) is qualified to do business in
California, or (C) is exempt from California withholding on other grounds set forth in such
certification, or (ii) evidence that the California Franchise Tax Board has authorized a partial
reduction in the amount required to be withheld from the Purchase Price payable to Seller or a
complete exemption from such withholding. If Seller fails to deliver such Qualifying Certificate
or other evidence authorizing a complete exemption from such withholding, Buyer shall not be
excused from its obligation to consummate the transactions contemplated herein, but rather shall
deduct and withhold from the portion of the Purchase Price payable to Seller, and instead pay to
the California Franchise Tax Board, an amount equal to three and one-third percent (3 1/3%) of the
“sales price of the California real property conveyed” by Seller in connection with the
transactions contemplated herein or such lesser amount of withholding as may be expressly
authorized by the California Franchise Tax Board, as provided and required by the California
Withholding Provisions. Any amount so withheld and paid to the California Franchise Tax Board
shall be deemed to have been paid by Buyer as a part of the Purchase Price. Buyer acknowledges and
agrees that it has received written notice of the CALFIRPTA withholding requirements.

     (h) A
Designation Agreement in the form attached hereto as
Exhibit D.

     (i) Such other customary documents and instruments as may be required by any other provision
of this Agreement or as may reasonably be required to carry out the terms and intent of this
Agreement; provided that Seller shall not be obligated to cause the delivery of any such instrument
or document that would increase or expand Seller’s obligations or liability under this Agreement.

     5.3 Buyer’s Deliveries

     At the Closing, Buyer shall deliver or cause to be delivered to Seller each of the following
instruments and documents, duly executed and acknowledged by Buyer, as appropriate:

     (a) Counterparts of the closing documents referenced in Sections 5.2(b) (if requested), (c),
and (h) above.

     (b) Buyer’s
Closing Certification, in the form attached hereto as
Exhibit E.

     (c) Such other documents and instruments as may be required by any other provision of this
Agreement or as may reasonably be required to carry out the terms and intent of this Agreement;
provided that Buyer shall not be obligated to cause the delivery of any such

J–13

 

instrument or document that would increase or expand Buyer’s obligations or liability under
this Agreement.

6. Easements

     Promptly following mutual execution of this Agreement, and in any event prior to Closing,
Seller and Buyer shall execute and cause to be recorded in the Official Records of Sacramento
County, California easement agreement(s), that are appurtenant to and run with the Land, to the
extent the same may be necessary to memorialize the then current rights and obligations of Seller,
as Lessor, and Buyer, as Lessee, as contemplated by Sections 2.2, 4.1(a), 4.1(b), 4.4 and Exhibit C
of the Ground Lease (the “ Easements ”). The Easements shall be in form and substance as
may be necessary for First American Title Insurance Company, or a title company reasonably
acceptable to Buyer, to include the same as insured easement parcel(s) in the legal description of
the title insurance policy to be issued to Buyer at Closing and sufficient for such title company
to issue a CLTA 103.4 or 103.7 endorsement (or its successor endorsement).

7. Prorations and Adjustments

     (a) At least ten (10) days before the Closing Date, Seller shall prepare and deliver, or cause
Escrow Holder to prepare and deliver, to Buyer an unaudited statement for the Property (the
“ Preliminary Proration Statement ”) showing prorations for rents and any additional
charges and expenses payable under the Ground Lease (but only to the extent collected before the
Closing Date), calculated as of 12:01 a.m. on the Closing Date, on the basis of a 365-day year.
Buyer and Seller shall agree upon any adjustments to be made to the Preliminary Proration Statement
before the Closing, and at the Closing, Buyer or Seller, as applicable, shall receive a credit
equal to the net amount due Buyer or Seller, as applicable, pursuant to the Preliminary Proration
Statement as finally agreed upon by Buyer and Seller.

8. Condemnation

     In the event of any condemnation of any portion of the Property there shall be a credit
against the Purchase Price due hereunder equal to the amount of any condemnation awards collected
by Seller as a result of any condemnation, or if any such award exceeds the Purchase Price, then
such amounts shall be deposited into escrow by Seller for the account of Buyer. If the awards have
not been collected as of the Closing, then such awards shall be assigned to Buyer at Closing.

9. Default

     (a) Buyer’s Default. If the Closing does not occur as a result of Buyer’s default hereunder,
then provided Seller is not in default hereunder, Seller’s sole and exclusive remedy shall be to
terminate this Agreement by giving written notice thereof to Buyer, whereupon the Deposit shall be
paid to Seller as liquidated damages, as Seller’s sole and exclusive remedy on account of such
default hereunder by Buyer; provided, however, that this provision will not limit Seller’s right to
receive reimbursement for attorneys’ fees pursuant to Section 14.1 below, nor waive or affect any
provisions of this Agreement which expressly state that they shall survive the termination of this
Agreement, and neither party shall have any further liability or obligation to the other hereunder,
except for provisions of this Agreement which expressly state that they shall survive

J–14

 

the termination of this Agreement. The parties acknowledge and agree that Seller’s actual
damages in the event of Buyer’s default would be extremely difficult or impracticable to determine.
After negotiation, the parties have agreed that, considering all the circumstances existing on the
date of this Agreement, the amount of the Deposit is a reasonable estimate of the damages that
Seller would incur in such event. The payment of the Deposit to Seller as liquidated damages under
the circumstances provided for herein is not intended as a forfeiture or penalty within the meaning
of Sections 3275 or 3369 of the California Civil Code, but is intended to constitute liquidated
damages to Seller pursuant to Sections 1671, 1676 and 1677 of the California Civil Code. By
signing this Agreement, each party specifically confirms the accuracy of the statements made above,
the reasonableness of the amount of liquidated damages agreed upon, and the fact that each party
was represented by counsel who explained, at the time this agreement was made, the consequences of
this liquidated damages provision.

     (b) Seller’s Default. If the Closing does not occur as a result of Seller’s default
hereunder, then, provided Buyer is not in default hereunder, Buyer may, at its sole election,
proceed with one of the following mutually exclusive alternatives:

          (i) waive such default and proceed with the Closing; provided, however, that this provision
will not waive or affect any of Seller’s other obligations under this Agreement to be performed
after the Closing with respect to any matter other than such default;

          (ii) terminate this Agreement, whereupon the Deposit shall be returned and paid to Buyer, and
Buyer shall be entitled to recover its costs (including, but not limited to, legal and other
professional fees) incurred in connection with the preparation and negotiation of this Agreement,
and otherwise neither party shall have any further liability or obligation to the other hereunder,
except for provisions of this Agreement which expressly state that they shall survive the
termination of this Agreement; or

          (iii) file in any court of competent jurisdiction an action for specific performance to cause
Seller to convey the Property to Buyer pursuant to the terms and conditions of this Agreement; but
Buyer shall not be entitled to recover monetary damages from Seller in connection with such
default; provided, however, that this provision will not limit Buyer’s right to receive
reimbursement for attorneys’ fees pursuant to Section 14.1 below, nor waive or affect any of
Seller’s other obligations under this Agreement to be performed after the Closing with respect to
any matter other than such default.

10. Expenses

     (a) All documentary stamp taxes county transfer taxes shall be borne and paid by the parties
as is customary practice in Sacramento County. All recording fees and city transfer taxes shall be
borne and paid by the parties as is customary practice in Sacramento County.

     (b) All Escrow and Closing costs charged by the Escrow Holder, and any investment charges or
escrow fees incurred with respect to the Escrow shall be borne and paid by the parties as is
customary practice in Sacramento County.

J–15

 

     (c) Buyer shall pay the premium and all other costs and expenses associated with any title
insurance Buyer chooses to have issued at or about the Closing. Seller shall not be required to
pay or contribute toward any such premium, cost or expense.

     (d) Except as provided in Section 9(b)(ii), each party shall pay its own attorneys’ fees in
connection with the negotiation, documentation and consummation of the transactions contemplated
hereunder. Each party shall pay its own costs of preparing and/or reviewing the Preliminary
Prorations Statement in connection with this Agreement.

     (e) Other costs, charges, and expenses shall be borne and paid as provided in this Agreement,
or in the absence of such provision, in accordance with the custom in the County of Sacramento.

11. Brokers

     (a) Buyer represents to Seller, and Seller represents to Buyer that there is no broker,
finder, or intermediary of any kind with whom such party has dealt in connection with this
transaction.

     (b) Seller agrees to indemnify and hold harmless Buyer, the partners, members, trustees,
shareholders, directors and officers of Buyer, any party owning a direct or indirect interest in
Buyer, the affiliates of Buyer, and the partners, members, trustees, shareholders, directors,
officers, employees and agents of each of the foregoing parties (the “ Buyer-Related
Parties ”), from and against all claims, demands, causes of action, judgments, and liabilities
which may be asserted or recovered for brokerage or finders fees, commissions, or other
compensation in connection with the transaction contemplated under this Agreement claimed by any
party other than Broker to be owing to such party due to any dealings between Seller and the party
claiming such fee, commission or compensation, including costs and reasonable attorneys’ fees
incident thereto. Buyer agrees to indemnify and hold harmless the Seller-Related Parties, from and
against all claims, demands, causes of action, judgments, and liabilities which may be asserted or
recovered for brokerage or finders fees, commissions, or other compensation in connection with the
transaction contemplated under this Agreement claimed by any party other than the Broker to be
owing to such party due to any dealings between Buyer and the party claiming such fee, commission
or compensation, including costs and reasonable attorneys’ fees incident thereto. The parties
hereto agree that the foregoing obligations of indemnification shall survive the Closing hereunder
or the expiration or termination of this Agreement, however caused.

12. Assignment

     This Agreement and all or any rights hereunder may be assigned by either party upon prior
notice to the other party; provided, however, that no such assignment shall relieve the assigning
party from its obligations, representations, warranties, indemnities or covenants under this
Agreement and no such assignment and assumption shall diminish the other party’s rights, remedies
and defenses under this Agreement or applicable law generally against the assigning party or its
assignee, as the case may be.

Property as industrial.

taken such action.

          (b) With respect to the Property, Buyer, on behalf of itself and its affiliates and its
successors and assigns, agrees not to, and agrees not to enter into any agreement that would permit
its successors or assigns or the successors or assigns of its affiliates to, take any voluntary
action, including any sampling of the soil or groundwater, or to initiate or encourage any action
by any third party, including any Governmental Authority or third party, which could reasonably be
expected to lead to a claim or demand by such Governmental Authority or third party under any
Environmental Law; provided that if any Law, including any Environmental Law, with respect to the
Property, or the defense of any third party claim against Buyer, requires Buyer or any of its
affiliates, successors or assigns to investigate, take action, initiate or encourage any such
action, Buyer will promptly notify Seller of such requirement and the content and timing of any
action that Buyer (or its affiliates, successors or assigns) proposes to take, and the parties
hereto shall consult with each other regarding the satisfaction of such requirement.

in connection with any action (whether the taking of soil or groundwater samples or otherwise)
prohibited by this Section 5(b), whether by Buyer or any other person, including any subsequent
owner of the Property.

proposed construction or repair area before initiation of the construction or the repair activity

diligently conduct Seller’s Remediation Obligation of such Hazardous Substance identified by the
testing to the extent required by the standard of performance set out above and as required by the
PCD and Governmental Restrictions. In the event Buyer anticipates incurring construction costs,
Buyer shall provide Seller reasonable advance notice before the costs are incurred.

timely fashion. Seller shall be responsible for all contacts and communications with Governmental
Authorities in connection with Seller’s Remediation Obligation and any other matters which are the
obligation of Seller. Seller also agrees to promptly reimburse Buyer for any reasonable
“out-of-pocket” costs (excluding any internal Buyer charges for administration, management or
supervision or other internal charges) incurred by Buyer in providing support to Seller to respond
to such notice, communication, or action.

     11. Regular Meetings. Seller and Buyer shall attend regular meetings with one another

     13. Inspection. Subject to applicable Law and Governmental Restrictions, Buyer shall
have the right to inspect and observe the Remedial Activities performed by or on behalf of Seller,
at reasonable times and after reasonable prior written notice to Seller. Inspection or failure to
inspect by Buyer shall not constitute a waiver of any of Buyer’s rights hereunder. However,
Buyer’s right or exercise of inspection shall not extend to or include any right or authority to
supervise or direct any of Seller’s employees, consultants, contractors or subcontractors in their
performance of any Remedial Activities. Further, such inspections must not negatively impact
Buyer’s operations.

     14. Notifications. Seller, Buyer, and any authorized tenant shall notify the other
parties within twenty-four (24) hours (or as soon as reasonably possible thereafter) following the
occurrence of any Release that causes contamination to soil or groundwater on the Property or
otherwise: (i) requires investigation, monitoring, remediation or removal under the Environmental
Law; (ii) may adversely affect any Remedial Activities or Remedial Activity Plans; (iii) is
reported to such party’s insurance carrier; or (iv) is reported to any Governmental Authority under
Environmental Law. Seller also agrees to give Buyer prompt advance notice (if and to the extent
Seller has knowledge of the same) of any inspection to be performed on any Property by any
Governmental Authority or PCD Agency in connection with the Remedial Activities or Seller’s
Remediation Obligation. Buyer also agrees to give Seller prompt advance notice (if and to the
extent Buyer has knowledge of the same) of any inspection to be performed on any Property by any
Governmental Authority with jurisdiction over the Remedial Activities or Seller’s Remediation
Obligation.

     15. Indemnity. Seller shall, at all times, indemnify, defend, protect, and hold
harmless Buyer (and its subtenants, assignees, successors and assigns) and any lender of Buyer (and

liens, suits, actions, debts, damages, costs, losses, liabilities, obligations, judgments, and
expenses (including, without limitation, court costs, expert and consultant fees, attorneys’ fees,
including those incurred on appeal, fines, penalties, and damage to, or loss suffered by, Buyer, or
the Property), of any nature whatsoever, arising from or relating to Pre-Term Environmental
Liabilities. Seller’s obligations hereunder shall arise whether or not any Governmental Authority
or individual has taken or threatened any action in connection with the presence of any Hazardous
Substance.

     16. Miscellaneous.

          (a) Attorneys’ Fees. In the event of any litigation between the parties with respect
to the Property, this Agreement, the Escrow, the performance of their obligations hereunder or the
effect of a termination under this Agreement, the losing party shall pay all costs and expenses
incurred by the prevailing party in connection with such litigation including, without limitation,
reasonable attorneys’ fees and disbursements. Any such attorneys’ fees and other expenses incurred
by either party in enforcing a judgment in its favor under this Agreement shall be recoverable
separately from and in addition to any other amount included in such judgment, and

J-41

 

such attorneys’ fees obligation is intended to be severable from the other provisions of this
Agreement and to survive and not be merged into any such judgment. Notwithstanding any provisions
of this Agreement to the contrary, the obligations of the parties under this Section 16(a) shall
survive any termination of this Agreement and the Closing.

          (b) Gender. Words of any gender used in this Agreement shall be held and construed to

convenient reference and in no way define, limit or prescribe the scope or intent of this Agreement
or any part hereof.

          (d) Construction. No provision of this Agreement shall be construed by any Court or
other judicial authority against any party hereto by reason of such party’s being deemed to have
drafted or structured such provisions. As used herein, the terms “include”, “including” and
similar terms shall be construed as if followed by the phrase “but not limited to.” The terms
“hereof”, “herein” and “hereunder”, and words of similar import, shall be construed to refer to
this Agreement as a whole, and not to any particular article or provision, except as expressly so
stated.

attached hereto and documents to be delivered pursuant hereto, shall constitute the entire
agreement and understanding of the parties, and there are no other prior or contemporaneous written

herein. The Schedules and Exhibits attached hereto are hereby incorporated in and made part of
this Agreement.

          (f) Successors. This Agreement and all of its terms and conditions shall run with the
land and shall be binding upon and inure to the benefit of the successors and assigns of Buyer and
Seller.

          (g) Time of Essence. Time is of the essence of this Agreement. In the computation of
any period of time provided for in this Agreement or by law, the day of the act or event from which
said period of time runs shall be excluded, and the last day of such period shall be included,
unless it is not a business day, in which case the period shall be deemed to run until the end of
the next day which is a business day.

          (h) Original Document. This Agreement may be executed by all parties in counterparts
in which event each shall be deemed an original, and all of which shall constitute one and the same

Exhibit 10.6

EMPLOYMENT AGREEMENT

     This Employment Agreement (“Agreement”), entered into effective December 1, 2005, is between
American Pacific Corporation., a Delaware corporation having its principal place of business at
3770 Howard Hughes Parkway, Suite 300, Las Vegas, Nevada 89109 (the “Company”), and Seth Van
Voorhees, an individual residing at the address set forth below his signature at the end of this
Agreement (the “Executive”) (collectively, “the parties”).

RECITALS

     1. The Company, through its subsidiary corporations, is engaged in the manufacture of
specialty chemicals, including perchlorate chemicals, sodium azide and HalotronTM fire suppression
agents, the design and manufacture of environmental protection products and other products as may
be acquired or developed over time, active pharmaceutical ingredients and registered intermediates
for commercial customers in the pharmaceutical industry, and real estate development.

     2. Executive has been employed by the Company since March 15, 2004, and is currently serving
as the Company’s Vice President and Chief Financial Officer.

     3. The Company desires to continue to employ Executive; to recognize Executive’s prior
contributions to the Company, particularly his role in the Company’s acquisition of the business of
Aerojet Fine Chemicals; and to assure itself of the continued services of Executive for the term of
this Agreement, and Executive desires both to continue his employment and to increase his knowledge
and experience in order to assume even greater responsibilities with the Company.

AGREEMENT

     ACCORDINGLY, the parties agree as follows:

     1. Period of Employment

          a. Basic Term. The Company shall continue to employ Executive to render services to the
Company in the position and with the duties and responsibilities described in Section 2 from the
date of this Agreement through December 1, 2008 (the “Term Date”), unless Executive’s employment is
terminated sooner in accordance with Section 4 below.

          b. Annual Renewal. Each year the term and provisions of this Agreement shall automatically
extend for a total three-year period and unless either party notifies the other in writing to the
contrary at least 30 days prior to the applicable October date that it, or he, does not want the
term to so extend.

1

 

     2. Position, Duties, Responsibilities

          a. Position: Executive is employed by the Company to render services to the Company in the
positions of Vice President and Chief Financial Officer, and shall perform all services appropriate
to those positions, as well as such other services as may reasonably be assigned by the Company.
The duties assigned to the Executive may be, but need not be, the same duties that are presently
assigned to the Executive, and may be changed from time to time. Initially, the Executive shall
act as the Chief Financial Officer of the Company and shall have all of the responsibilities and
duties, including fiduciary duties, associated with such position. In addition, during such
periods of time as the Executive serves as the Vice President or other officer of the Company, the
Executive’s service as an officer shall additionally be governed by the Company’s Bylaws from time
to time in effect, and by the laws of the state of the Company’s incorporation. Executive shall at
all times perform his duties and discharge his responsibilities under this Agreement and under
applicable law diligently and conscientiously, and to the best of his ability, and shall direct his
best efforts to further and maximize the business and interests of the Company and its
shareholders, in accordance with sound business practices and applicable laws and regulations.
Executive shall report to the Chief Executive Officer of the Company.

          b. Other Activities. Except upon the prior written consent of the Company, Executive will not
(i) accept any other employment, or (ii) engage, directly or indirectly, in any other business
activity (whether or not pursued for pecuniary advantage) that is or may be in conflict with, or
that might place Executive in a conflicting position to that of, the Company. Without limitation,
the Executive shall not act in any advisory or other capacity for any individual, firm, association
or corporation other than the Company and its subsidiary corporations in matters in any way
pertaining to any business or undertaking in any way similar to or competitive with the business or
activities of the Company and its subsidiary corporations. Notwithstanding the foregoing, while
the Company does not request Executive’s service on the boards of directors of other corporations,
the Company does not, in principle, object to such service where Executive would have no conflict
of interest with duties owed to the Company.

          c. Proprietary Information. “Proprietary Information” is all information and any idea in
whatever form, tangible or intangible, pertaining in any manner to the business of the Company and
its subsidiary corporations, or its employees, clients, consultants, or business associates, which
was produced by any employee of the Company or its subsidiary corporations, in the course of his or
her employment or otherwise produced or acquired by or on behalf of the Company or its subsidiary
corporations. All Proprietary Information not generally known outside of the Company’s
organization, and all Proprietary Information so known only through improper means, shall be deemed
“Confidential Information.” Without limiting the foregoing definition, Proprietary and
Confidential Information shall include, but not be limited to: (i) formulas, teaching and
development techniques, processes, trade secrets, computer programs, electronic codes, inventions,
improvements, and research projects; (ii) information about costs, profits, markets, sales, and
lists of customers or clients; (iii) business, marketing, and strategic plans; and (iv) employee
personnel files and compensation information. Executive should consult any Company procedures
instituted to identify and protect certain types of Confidential Information, which are considered
by the Company to be safeguards in addition to the protection provided by

2

 

this Agreement. Nothing contained in those procedures or in this Agreement is intended to limit
the effect of the other.

          d. General Restrictions on Use. During the Period of Employment, Executive shall use
Proprietary Information, and shall disclose Confidential Information, only for the benefit of the
Company and as is necessary to carry out his responsibilities under this Agreement. Following
termination, Executive shall neither, directly or indirectly, use any Proprietary Information nor
disclose any Confidential Information, except as expressly and specifically authorized in writing
by the Company. The publication of any Proprietary Information through literature or speeches must
be approved in advance in writing by the Company.

     3. Compensation.

     In consideration of the services to be rendered under this Agreement, Executive shall be
entitled to the following:

          a. The Company shall continue to pay Executive as compensation for services a base salary at
the annual rate of $296,800 (which includes an automobile allowance of $16,800), or at such higher
rate as the Compensation Committee of the Board of Directors may determine from time to time. Such
salary shall be payable in accordance with the standard payroll procedures of the Corporation.
Once the Corporation’s Compensation Committee of the Board of Directors has increased such salary,
it thereafter shall not be reduced. The annual compensation specified in this Section 3, together
with any increases in such compensation that the Compensation Committee of the Board of Directors
may grant from time to time, is referred to in this Agreement as “Base Compensation.”

          b. The Company (or the employing subsidiary corporation) shall review the above Base
Compensation on or about June 1 of each calendar year, and may make any increase it deems
appropriate. Any such increase shall be made effective as soon as may be practicable following
each review.

          c. Executive shall be eligible to participate in all the Company’s (or the employing
subsidiary corporation’s) benefit plans, and to receive perquisites of employment, as established
by the Company, and as may be amended from time to time in the Company’s sole discretion at least
equal to those provided to other Company officers.

4. Termination of Employment

          a. Termination By Death. Executive’s employment shall terminate automatically upon the death
of Executive. Company shall pay to Executive’s beneficiaries or estate, as appropriate, any
compensation then due and owing, and shall continue to pay Executive’s salary and benefits, through
the second full month after Executive’s death. As of the date of death, all stock options
available to Executive through the Term Date shall be deemed accelerated and vested, and may be
exercised by the appropriate representative beneficiary of Executive’s estate. Thereafter, all
obligations of Company under this Agreement shall cease.

3

 

Nothing in this Section shall affect any entitlement of Executive’s heirs to the benefits of
any life insurance plan or other applicable benefits.

          b. Termination By Disability. If, in the sole opinion of the Company, Executive shall be
prevented from properly performing his duties hereunder by reason of any physical or mental
incapacity for a period of more than ninety (90) days in the aggregate in any twelve-month period,
then, to the extent permitted by law, Company may terminate Executive’s employment. Company shall
pay to Executive all compensation to which Executive is entitled up through the last day of the
month in which the 90th day of incapacity occurs, and thereafter, all of Company’s obligations
under this Agreement shall cease. Nothing in this Section shall affect Executive’s rights under
any disability plan in which he is a participant.

          c. Termination By Company Not For Cause. At any time, Employer may terminate the Period of
Employment Not For Cause for any reason by providing Executive thirty (30) days’ advance written
notice, provided that Executive shall, in addition to all compensation due and owing through the
last day actually worked, receive the following:

             (i) The Company shall pay Executive a severance payment equal to three years of the
Executive’s then current Base Compensation. The severance payment will be made in the form of
salary continuation for three years (the “Severance Period”), payable on the Company’s normal
payroll schedule.

             (ii) All shares of stock granted to Executive and all unexercised options to purchase Company
stock that are unvested at the time of the termination of employment shall become fully vested and
exercisable.

             (iii) The amount of any payment provided for in this Section 4.c shall not be reduced, offset
or subject to recovery by the Company by reason of any compensation earned by Executive as the
result of employment by another employer during the Severance Period so long as Executive does not
violate the provisions of Section 6.d below.

             (iv) The severance benefits described in this Section 4.c shall be conditioned upon
Executive’s continued observance of the obligations described in Section 6.d throughout the
Severance Period. Should Executive engage in or pursue any of the activities described in Section
6.d at any time during the Severance Period, all severance benefits described in this Section 4.c
shall cease. In addition, receipt of the benefits described in this Section 4.c are contingent
upon Executive executing a release of claims against the Company.

          d. Termination By Company For Cause. At any time, and without prior notice, the Company may
terminate Executive’s employment For Cause (as defined below). The Company shall pay Executive all
compensation then due and owing; thereafter, all of the Company’s obligations under this Agreement
shall cease. Termination for “Cause” shall mean termination of Executive’s employment because of
Executive’s (i) involvement in fraud, misappropriation or embezzlement related to the business or
property of the company; (ii) conviction for, or guilty plea to, a felony; (iii) willful material
breach of this Agreement; (iv) willful and continued failure to substantially perform his duties
under this Agreement,

4

 

provided, however, that if such Cause is reasonably curable, the company shall not terminate Executive’s
employment hereunder unless the Company first gives notice of its intention to terminate and the
grounds of such termination, and the Executive has not, within thirty (30) days following receipt
of this notice, cured such Cause.

          e. By Executive Not for Good Reason. At any time, Executive may terminate the Period of
Employment for any reason, with or without cause, by providing Employer thirty (30) days’ advance
written notice. Employer shall have the option, in its complete discretion, to make termination of
the Period of Employment effective at any time prior to the end of such notice period, provided
Employer pays Executive all compensation due and owing through the last day actually worked, plus
an amount equal to the base salary Executive would have earned through the balance of the above
notice period, thereafter, all of Employer’s obligations under this Agreement shall cease.

          f. By Executive for Good Reason. Executive may terminate, without liability, the Period of
Employment for Good Reason (as defined below), provided Executive gives Employer ninety (90) days’
advance written notice of the reason for termination and his intent to terminate this Agreement.
During this period, Employer shall have an opportunity to correct the condition constituting Good
Reason. If the condition is remedied within this period, Executive’s notice to terminate shall be
rescinded automatically; if not remedied, termination of the Period of Employment shall become
effective upon expiration of the above notice period. In this event, Employer shall pay Executive
all compensation due and owing through the last day actually worked including any accrued but
unused vacation. Employer shall also have the option, in its complete discretion, to make
termination effective at any time prior to the end of the notice period, provided that Employer
pays Executive all compensation due and owing through the balance of the notice period (not to
exceed ninety (90) days). Executive shall be entitled to exercise his right to terminate this
Agreement for Good Reason only if he gives the required notice not more than sixty (60) days after
the occurrence of the event that is the basis for the Good Reason. If Executive terminates the
Period of Employment for Good Reason pursuant to the provisions of this Section 4.f, Executive
shall receive the severance benefits described in and pursuant to the terms of subparagraph 4.c
above.

     The following shall constitute a termination by Executive for “Good Reason”: (A) without
Executive’s express written consent there is an assignment to the Executive of any duties or the
reduction of the Executive’s duties, either of which is materially inconsistent with Executive’s
position or responsibilities with the Company in effect immediately prior to such assignment,
except in connection with the termination of employment For Cause (as defined in Section 4.d
above), or due to disability or death; (B) there is a reduction by the Company in the Executive’s
annual salary then in effect; (C) a material reduction by the Company in the kind or level of
benefits provided to Executive under any benefit plan of the Company in which the Executive is
participating with the result that Executive’s overall benefits package is significantly reduced;
(D) any material breach by the Company of any material provision of this Agreement; or (E) a
relocation of Executive’s principal place of employment by more than fifty (50) miles, provided and
only if such change, reduction or relocation is effected by the Employer without Executive’s
consent.

          g. By Executive Following Change in Leadership. Executive may terminate, without liability,
the Period of Employment if another individual, other than Executive, succeeds the current
incumbent as President and Chief Executive Officer of the Company, provided Executive gives
Employer ninety (90) days advance written notice of this reason for termination of his employment.
If Executive resigns for this reason, he will receive the larger of (a) the benefits owed him upon
occurrence of a “corporate transition,” as set forth in Section 4.i.(iii) below, or (b) the sum of
Four Hundred Thousand Dollars ($400,000), times the number of Executive’s full years of employment
at the Company, up to a maximum payment of $1,200,000.

          h. Good Faith Commitment to Negotiate Transition Agreement. Company and Executive mutually
agree to negotiate in good faith with regard to a Transition Agreement, which would be offered to
Executive in the event that he is replaced as Vice President and Chief Financial Officer. For his
part, Executive agrees that he will utilize his best efforts to assist in a smooth transition to
any successor Vice President and Chief Financial Officer.

          i. Corporate Transaction.

             (i) Corporate Transaction Defined. For purposes of this Agreement, a “Corporate Transaction”
shall include any of the following transactions to which the Company is a party: (A) a merger or
consolidation in which the Company is not the surviving entity and securities representing more
than fifty percent (50%) of the total combined voting power of the Company’s outstanding securities
are transferred to holder different from those who held such securities immediately prior to such
merger; (B) the sale, transfer or other disposition of all or substantially all of the assets of
the Company in liquidation or dissolution of the Company; (C) any reverse merger in which the
Company is the surviving entity but in which securities representing more than fifty percent (50%)
of the total combined voting power of the Company’s outstanding securities are transferred to
holder different from those who held such securities immediately prior to such merge; or (D) any
cash dividend paid by the Company that, in the aggregate with all other dividends paid in any
twelve month period, is greater than the combined earnings of the Company for the Company’s two
fiscal years prior to such dividend payment date. In addition, a Corporate Transaction shall also
include a “Change of Control” as such term is defined in the Company’s 2001 Stock Option Plan, a
“Capital Change of the Company” as such term is defined in the Company’s 1997 Stock Option Plan or
a “Corporate Capital Transaction” as such term is defined in the Company’s 1991 Stock Option Plan.

             (ii) Acceleration of vesting at time of Corporate Transaction. Should a Corporate Transaction
take place, all shares of stock granted to Executive and all unexercised options to purchase
Company stock granted to the Executive that are unvested at the time of the Corporate Transaction
shall become fully vested and exerciseable.

             (iii) Benefits Upon Occurrence of Corporate Transaction. Upon the occurrence of a Corporate
Transaction and subject to the obligations in Section 6.d.-e. below, Executive shall be entitled to
the benefits described in Section 4.c above, regardless of whether the Executive’s employment is
terminated in connection with such Corporate Transaction. In the event

6

 

the event the Executive collects benefits pursuant to this Section 4.i.(iii) the Executive
shall lose the right to terminate the Agreement for Good Reason.

     5. SECTION 280G PAYMENTS; COMPLIANCE WITH SECTION 409A

          a. Gross-Up Payment. In the event it is determined that any payment or distribution of any
type to or for the benefit of the employee, pursuant to this Agreement or otherwise, by the
Corporation, any Person who acquires ownership or effective control of the Corporation, or
ownership of a substantial portion of the assets of the Corporation (within the meaning of section
280G of the Code and the regulations, including proposed regulations, thereunder) or any affiliate
of such Person (the “Total Payments”) would be subject to the excise tax imposed by section 4999 of
the Code or any interest or penalties with respect to such excise tax (such excise tax, together
with any such interest and penalties, are collectively referred to as the “Excise Tax”), then the
Employee shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount
such that, after payment by the Employee of all taxes, (including any interest or penalties imposed
with respect to such taxes), including any Excise Tax, imposed upon the Gross-Up Payment, the
Employee retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Total
Payments.

          b. Determination by Accountant. All mathematical determinations and determinations as to
whether any of the Total Payments are “parachute payments” (within the meaning of section 280G of
the Code and the regulations, including proposed regulations, thereunder), in each case which
determinations are required to be made under Section 5, including whether a Gross-Up Payment is
required, the amount of such Gross-Up Payment, shall be made by an independent accounting firm
selected by the Employee from among the largest four accounting firms in the United States (the
“Accounting Firm”). The Accounting Firm shall provide to the Corporation and to the Employee its
determination (the “Determination”), together with detailed supporting calculations regarding the
amount of any Gross-Up Payment and any other relevant matter, within ten days after the occurrence
of an event which would trigger a parachute payment, or at such earlier time following such an
event as is requested by the Employee (if the Employee reasonably believes that any of the Total
Payments may be subject to the Excise Tax). If the Accounting Firm determines that no Excise Tax
is payable by the Employee, it shall furnish the Employee with a written statement that such
Accounting Firm has concluded that no Excise Tax is payable (including the reasons therefore) and
that the Employee has substantial authority not to report any Excise Tax on the Employee’s federal
income tax return. If a Gross-Up Payment is determined to be payable, it shall be paid to the
Employee within ten days after the Determination is delivered to the Corporation or the Employee.
Any determination by the Accounting Firm shall be binding upon the Corporation and the Employee,
absent manifest error.

     As a result of uncertainty in the application of section 4999 of the Code at the time of the
initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments not
made by the Corporation and members of the Corporation should have been made (“Underpayment”), or
that Gross-Up Payments will have been made by the Corporation and members of the Corporation that
should not have been made (“Overpayments”). In either such event, the Accounting Firm shall
determine the amount of the Underpayment or Overpayment

7

 

that has occurred. In the case of an Underpayment, the Corporation promptly shall pay, or
cause to be paid, the amount of such Underpayment to or for the benefit of the Employee. In the
case of an Overpayment, the Employee shall, at the direction and expense of the Corporation, take
such steps as are reasonably necessary (including the filing of returns and claims for refund),
follow reasonable instructions from, and procedures established by, the Corporation, and otherwise
reasonably cooperate with the Corporation to correct such Overpayment; provided, however that (1)
Employee shall not in any event be obligated to return to the Corporation an amount greater than
the net after-tax portion of the Overpayment that he has retained or recovered as a refund from the
applicable taxing authorities, and (2) this provision shall be interpreted in a manner consistent
with the intent of Section 5(a), which is to make the Employee whole, on an after-tax basis, from
the application of the Excise Tax, it being understood that the correction of an Overpayment may
result in the Employee repaying to the Corporation an amount that is less than the Overpayment.

          c. Amendment to Comply with Section 409A. Executive agrees that the Company may amend this
Agreement (including amendments that would delay the payment of certain amounts hereunder) to meet
the requirements of Section 409A of the Internal Revenue Code, as amplified by any Internal Revenue
Service or U.S. Treasury Department regulations or guidance, to the extent the Company in good
faith deems appropriate or advisable.

     6. Termination Obligations

          a. Return of Company’s Property. Executive hereby acknowledges and agrees that all personal
property, including, without limitation, all books, manuals, records, reports, notes, contracts,
lists, blueprints, and other documents, or materials, or copies thereof, and equipment furnished to
or prepared by Executive in the course of or incident to Executive’s employment, belong to Company
and shall be promptly returned to Company upon termination of Executive’s employment.

          b. Representations and Warranties Survive Termination of Employment. The representations and
warranties contained herein, except Executive’s obligations under Section 2.b, shall survive
termination of Executive’s employment and expiration of this Agreement.

          c. Cooperation in Pending Work. Following any termination of Executive’s employment,
Executive shall fully cooperate with Company in all matters relating to the winding up of pending
work on behalf of Company and the orderly transfer of work to other employees of Company.
Executive shall also cooperate in the defense of any action brought by any third party against
Company that relates in any way to Executive’s acts or omissions while employed by Company. If
Executive’s cooperation in the defense of any such action requires more than ten (10) hours of
Executive’s time, the Executive and Company shall agree on appropriate remuneration for Executive’s
time and expenses.

          d. Noncompetition. Executive acknowledges and agrees that during his employment with the
Company, he has had access to confidential information and the activities forbidden by this
subsection would necessarily involve the improper use and disclosure of this

8

 

confidential information. To forestall this use or disclosure, Executive agrees that during
the Severance Period described in Section 4.c, or for two years after the termination of Executive
for reasons other than by Company Not for Cause, Executive shall not, directly or indirectly, (i)
divert or attempt to divert from the Company (or any Affiliate) any business of any kind in which
it is engaged; (ii) employ or recommend for employment any person employed by the Company (or any
Affiliate); or (iii) engage in any business activity that is competitive with the Company (or any
Affiliate) in any state where the Company conducts its business, unless Executive can prove that
any of the above actions was done without the use of confidential information. In addition to the
above restrictions on noncompetitive activity, and regardless of whether any use of confidential
information is involved, Executive agrees that during the Severance Period Executive shall not,
directly or indirectly, (i) solicit any customer of the Company (or any Affiliate) known to
Executive (while he was employed by the Company) to have been a customer with respect to products
or services competitive with products or services offered by the Company; or (ii) solicit for
employment any person employed by the Company (or any Affiliate).

          e. Confidential Information.

             (i) The Executive shall never, either during the Term of the Executive’s Employment by the
Company or thereafter, use or employ for any purpose or disclose to any other individual or entity
any Confidential Information. The Executive acknowledges and agrees that all Confidential
Information is proprietary to the Company, is extremely important to the Company’s business, and
that the use by or disclosure of such Confidential Information to a Competitor could materially and
adversely affect the Company, its business and its customers.

             (ii) For purposes of this Agreement, the term “Company” shall refer to the Company and each of
its subsidiary corporations, and any other corporation or entity that is owned or controlled,
directly or indirectly, by the Company or that is under common ownership or control with the
Company.

             (iii) For purposes of this Agreement, the term “Confidential Information” shall mean
information in any form that is not generally known to the public that relates to the Company’s
past, present or future operations, processes, products or services, or to any research,
development, manufacture, purchasing, accounting, engineering, marketing, merchandising,
advertising, selling, leasing, financing or business methods or techniques (including without
limitation customer lists, records of customer services, usages and requirements, sketches and
diagrams of Company or customer facilities and like and similar information relating to actual or
prospective customers) that is or may be related thereto. All information disclosed to the
Executive or to which the Executive obtains access during any Term of the Executive’s Employment
with the Company, whether pursuant to this Agreement or otherwise, or to which the Executive
obtains access by reason of his employment by the Company, that the Executive has a reasonable
basis to believe is or may be Confidential Information, shall be presumed for purposes of this
Agreement to be Confidential Information.

failure to exercise and no delay in exercising any right, remedy, or power under this Agreement
shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy,
or power under this Agreement preclude any other or further exercise thereof, or the exercise of
any other right, remedy, or power provided herein or by law or in equity.

     10. Assignment; Successors and Assigns

     Executive agrees that he will not assign, sell, transfer, delegate or otherwise dispose of,
whether voluntarily or involuntarily, or by operation of law, any rights or obligations under this
Agreement, nor shall Executive’s rights be subject to encumbrance or the claims of creditors. Any
purported assignment, transfer, or delegation shall be null and void. Nothing in this

10

 

Agreement shall prevent the consolidation of the Company with, or its merger into, any other
corporation, or the sale by the Company of all or substantially all of its properties or assets, or
the assignment by the Company of this Agreement and the performance of its obligations hereunder to
any successor in interest. In the event of a change in ownership or control of the Company, the
terms of this Agreement will remain in effect and shall be binding upon any successor in interest.

to the benefit of the parties and their respective heirs, legal representatives, successors, and
permitted assigns, and shall not benefit any person or entity other than those enumerated above.

     11. Severability; Enforcement

     If any provision of this Agreement, or the application thereof to any person, place, or
circumstance, shall be held by a court of competent jurisdiction to be invalid, unenforceable, or
void, the remainder of this Agreement and such provisions as applied to other persons, places, and
circumstances shall remain in full force and effect.

held in or near Clark County, Nevada, before an arbitrator licensed to practice law in the State of
