               such use without charge;

          c.   Subcontracts of any tier under Government prime contracts other
               than W-7405-ENG-48 if the Contracting Officer having cognizance
               of the Prime contract (i) approves a Subcontract specifically
               authorizing such Use or (ii) otherwise authorizes such use in
               writing; and

          and upkeep. If the RPs are used on non-Subcontract work, these costs
          may be allocated to the appropriate customer, provided the allocation
          does not include the University. In the case of RP consumables,, the
          Subcontractor agrees to provide those utilized in the continuous
          operation of the RPs, while those used in the actual processing of
          optics are to be properly allocated to the price of the optics
          themselves.

     3.   Nothing in this Subcontract shall abrogate any right of the University
          to withdraw Government Owned Equipment from the Subcontractor upon
          reasonable notice, subject to provision for equitable adjustment that
          may exist in an active University Subcontract affected by such
          withdrawal. The University is not responsible for the effect of such
          withdrawal on any work being performed by the Subcontractor under any
          other contract or subcontract.

ARTICLE 8 - APPROVAL OF TECHNICAL DATA

If this Subcontract requires the Subcontractor to furnish any drawings,
specifications, diagrams, layouts, schematics, descriptive literature,
illustrations, schedules, performance or test data, or other technical data for
approval by the University prior to Subcontractor performance, the approval of
the data by the University shall not relieve the Subcontractor from
responsibility for any errors or omissions in such data or from responsibility
for complying with the requirements of this Subcontract, except as specified
below. Any work done prior to such approval shall be at the Subcontractor's
risk.

If the data includes any variations from the Subcontract requirements, the
Subcontractor shall describe such variations in writing at the time of
submission of the data. If the University approves any such variation(s), a
change order to the Subcontract shall be issued by the University and, if
appropriate, a bilateral modification to the Subcontract shall be negotiated.

                                STATEMENT OF WORK

                               Production (P3/P4)

                                   NID0075521

1.   OBJECTIVE

The objective of this Subcontract is to perform optical finishing on 588
production optics (amplifiers, polarizers, and mirrors) to support the National
Ignition Facility (NIF), a 192 beam laser capable of fusion ignition. An option
for an additional 690 optics is also included in this Subcontract. The
Subcontractor shall utilize the technologies and facilities established by them
under NIF/ICF development, facilitization, and pilot production for the
manufacturing of these optics.

2.   WORK REQUIREMENTS

The Subcontractor shall provide all labor, facilities, equipment (other than
that provided as GFE) and processes needed to finish the quantities of optics
listed in section 3 of this SOW. Much of the equipment required to finish these
optics has been provided as GFE. Consistent with ARTICLE 7 - PROPERTY of the
Subcontract Schedule of Articles, the Subcontractor shall be responsible for the
cost of maintenance and repairs of all GFE. However, no equipment modifications
or upgrades shall be performed on GFE without the written approval of the
University's Procurement Representative. In addition, the Subcontractor shall
maintain a qualified workforce capable of manufacturing NIF optics with
stringent specifications.

The University shall provide all optical blanks for finishing under this
Subcontract as well as the epoxy kits, shaped cladding strips for the laser slab
assemblies, PET-G containers and shipping crates. The Subcontractor shall notify
the University in writing sixty days in advance of their needs for this
University supplied material. The University will ensure that all requests are
met in a timely manner to avoid shortages that may impact the Subcontractor's
production schedule.

3.   QUANTITIES

Table 1 shows the number and types of optics to be fabricated under this
Subcontract that covers twelve months of what is referred to by the University
as P3 Production. The numbers and types correspond to a baseline production
scenario that represent the required production rate for this Subcontract.

4.   SPECIFICATIONS

The specifications for each optical component are contained within the drawings
that are listed in Appendix A. Prior to commencement of work the Subcontractor
shall confirm with the University Technical Representative that they have the
most current drawings. All drawings and appendices should already be in the
Subcontractor's possession, however, any that are not will be sent upon request.
Note that these drawings have been written in accordance with the ISO 10110
standard. The optics shall be finished to meet the specifications on the
finished optics drawings listed in Appendix A. The corresponding material
drawings and specifications are listed in Appendix B. The attachment "Detailed
Cladding Guidance," Appendix D, provides details on cladding that augments the
drawings and supersedes them in places.

The ability of the Subcontractor to meet the transmitted wavefront requirements
of polarizers is dependent on the material inhomogeneity. The best commercially
available material may be insufficient to meet the transmitted wavefront
specification. Any material that is unable to be finished, meaning a reasonable
effort has been made by the Subcontractor to meet the transmitted wavefront
specification, shall be finished to the prefigured specifications in drawing
AAA96-105515. If after award of this Subcontract, the Subcontractor should
develop the capability to preferentially figure optics to compensate for
material inhomogeneity, then the additional cost for that effort will be
negotiated as a separate subcontract action.

Laser glass inhomogeneity will also impact finished transmitted wavefront
performance. To address this issue amplifier slabs shall be divided into two
classes of material as illustrated in the table below.

5.   MANUFACTURING YIELD/BREAKAGE

The optical blanks that are shaped by the Subcontractor have significant value,
particularly amplifier slabs ($15K - $30K each) and polarizers ($11K - $15K
each). Breakage of these optics results in a loss to the NIF program. Also,
excessive breakage of amplifier slabs may force the University to initiate an
additional melting campaign at an approximate cost of $10M - $15M. Given the
value of these blanks, it is imperative that reasonable efforts be taken by the
Subcontractor to protect these optics from damage during processing.

Based on breakage rates from past ICF projects, the University expects the
breakage rate not to exceed 2% over a quantity of at least 25 of each optic type
(amplifier slab, polarizer, or mirror). A breakage rate from 2%-5% shall result
in a report to the University Technical Representative to present the current
issues and mitigation strategy. Breakage rates exceeding 5% may result in a
STOP-WORK ORDER being issued by the University, consistent with the General
Provisions of this Subcontract. If a STOP-WORK ORDER is issued the Subcontractor
shall cease all work until a mitigation strategy aimed at solving the problem,
is implemented. Mitigation measures could include such actions as improved
training, fixture modifications, machine interlock systems, removal of an
employee from this subcontract. Etc.

Breakage shall be defined as damage caused by the Subcontractor that renders the
optic useless. Non-Conformance Reports (NCRs) shall not apply against breakage
determinations.

6.   REPORTING REQUIREMENTS

          A)   WEEKLY PROGRESS REPORTS - INVENTORY TRACKING SHEET (ITS)

               The Subcontractor shall send a status list of all optics within
               their Facility utilizing the established Excel compatible ITS
               spreadsheet Utilized in previous subcontracts B335188 and
               B514527.

The following documents, while not specific deliverables under this Subcontract,
shall be maintained by the Subcontractor and updated as necessary to reflect any
changes or improvements. These documents were originally developed and approved
as part of the scope of work under Subcontract B335188 and maintained under
Subcontract B514527. The Subcontractor shall notify the University's Technical
Representative if any changes are made to the QA/QC Plan or to any of the
Process Materials and Procedures, providing appropriate details for the
University to determine the impact to finished optics. A brief description of
each document follows, though the complete requirement is contained in the
