     This Note is the Special Advance Promissory Note referred to in, and is

are deemed incorporated herein in full. All capitalized terms used herein,
unless otherwise specifically defined in this Note, shall have the meanings
ascribed to them in the Loan Agreement. This Note amends and restates in full
the Amended and Restated Secured Promissory Note of Company dated as of

     The rate of interest in effect hereunder shall increase or decrease by an
amount equal to any increase or decrease in the Prime Rate effective as of the
opening of business on the date that any such change in the Prime Rate occurs.

--------------------------------------------------------------------------------

 

     Upon the occurrence of an Event of Default (excluding any Event of Default
expressly waived in writing by AMPAC on or before the date hereof), unless such
Event of Default is expressly curable pursuant to the Transaction Documents and
has been cured as provided therein, AMPAC shall have all of the default rights
and remedies set forth in the Loan Agreement and the other Transaction
Documents.

     Time is of the essence of this Note. To the fullest extent permitted by
applicable law, Borrower, for itself and its legal representatives, successors
and assigns, expressly waives presentment, demand, protest, notice of dishonor,
notice of non-payment, notice of maturity, notice of protest, presentment for
the purpose of accelerating maturity, diligence in collection, and the benefit
of any exemption or insolvency laws.

     Wherever possible, each provision of this Note shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Note shall be prohibited or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity without
invalidating the remainder of such provision or remaining provisions of this
Note. No delay or failure on the part of AMPAC in the exercise of any right or
remedy hereunder shall operate as a waiver thereof, nor as an acquiescence in
any default, nor shall any single or partial exercise by AMPAC of any right or
remedy preclude any other right or remedy. AMPAC, at its option, may enforce its
rights against any collateral securing this Note without enforcing its rights
against Borrower, any guarantor of the indebtedness evidenced hereby or any
other property or indebtedness due or to become due to Borrower. Borrower agrees
that, without releasing or impairing Borrower’s liability hereunder, AMPAC may
at any time release, surrender, substitute or exchange any collateral securing
this Note and may at any time release any party primarily or secondarily liable
for the indebtedness evidenced by this Note.

     This Note shall be governed by, and construed and enforced in accordance
with, the laws of the State of California.

     EACH OF AMPAC AND BORROWER HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY, IF
ANY, IN ANY ACTION TO ENFORCE, DEFEND, INTERPRET OR OTHERWISE CONCERNING THIS
NOTE.

     IN WITNESS WHEREOF, Borrower has caused this Note to be duly executed and
delivered in Los Angeles, California as of the date first above written.
