* Federal Acquisition Regulation (FAR), paragraph 19.708(b) prescribes the use
of the clause at FAR 52.219-9 entitled "Small, Small Disadvantaged, and
Women-Owned Small Business Subcontracting Plan." The following is a suggested
model for use when formulating such a subcontracting plan. While this model plan
has been designed to be consistent with FAR 52.219-9, other formats of a
subcontracting plan may be acceptable. However, failure to include essential
information as exemplified in this model may be cause for either a delay in
acceptance or the rejection of a bid or offer where the clause is applicable.
Further, the use of this model is not intended to waive other requirements that
may be applicable under FAR 52.219-9. "SUBCONTRACT," as used in this clause,
means any agreement (other than one involving an employer-employee relationship)
entered into by a Federal Government prime contractor or subcontractor calling
for supplies or services required for performance of the contract or subcontract

1. Type of plan (check one):

|X|   Individual Plan (All elements developed specifically for this contract and
      applicable for the full term of this contract).

____  Master Plan (Goals developed for this contract; all other elements
      standard; must be renewed every year).

____  Commercial Products Plan (Contractor sells large quantities of the
      off-the-shelf commodities to many Government agencies. Plans/goals
      negotiated by a lead agency on a company-wide basis rather than for
      individual contracts. Plan effective only during the year for which it is
      approved. The contractor must provide a copy of the lead agency approval).

2. Goals:

State separate dollar and percentage goals for small business, small
disadvantaged business, and women-owned small business in the following format.
(For a contract with option, provide a separate statement for the basic contract
and individual statements for each option year).

Commodore ASI's plan numbers shown below are based on the assumption that we
will be awarded $3,000,000 in task orders per year and the nature of the work
will afford opportunities to subcontract about 10% of the effort to small and
small disadvantaged and women owned firms ands 3% to large businesses like
analytical laboratories.

      A.    Total estimated dollar value and percent of planned subcontracting
            with small businesses (include small disadvantaged and women-owned
            small businesses): (77% of "C")

            through 5

      B.    Total estimated dollar value and percent of planned subcontracting
            with large businesses (all business concerns classified as "other
            than small"): (23% of "C")

            $450,000 basic contract and $50,000 for option years 1 through 5

      C.    Total estimated dollar value of all planned subcontracting, i.e.,
            the sum of A and B above:

            $1,950,000 (100%) basic contract $1,950,000 (100%) option years 1

CAS plans on subcontracting with specialty firms for the following services:
drilling, analytical laboratories, geophysical surveys, land surveys, asbestos
surveys, systems (transportation planning), training, major investment studies,
traffic noise analysis, and specific expert studies in disciplines or locations
that it would be more cost effective to subcontract out these types of services.
CAS identified a woman owned firm, Environmental Management Resources of
Lawrence KS and an 8a firm, LS Gallegos & Associates of Englewood CO as two
example small disadvantaged firms whom we could access to meet our goals.

(Attach additional sheets if necessary).

      G.    A description of the method used to develop the subcontracting goals
            for small, small disadvantaged, and women-owned small business
            concerns: i.e., explain the method and state the quantitative basis
            (in dollars) used to establish the percentage goals; how the areas
            to be subcontracted to small, small disadvantaged, and women-owned
            small business concerns were determined; and how the capabilities of
            small, small disadvantaged, and women-owned small business concerns
            were determined. Include any source list used in the determination
            process.

The areas of this procurement to be subcontracted will be identified by the
program and scientific staff to determine the requisite skill required to
satisfy subcontract requirements. CAS reviewed the GSA website for available
SDB/WO subcontractors. Our program staff will identify other specialty areas of
needs and candidate subcontractors based on their familiarity with our in-house
capabilities and location of work. It is recognized that this contract could
offer opportunities for qualified small and small disadvantaged business firms
that support environmental investigation and field services using specialized
equipment or facilities..

      H.    Indirect costs have |X| have not _____ been included in the dollar
            and percentage subcontracting goals stated above. (Check one).

      I.    If indirect costs have been included, explain the method used to
            determine the proportionate share of such costs to be allocated as
            subcontracts to small, small disadvantaged, and women-owned small
            business concerns.

CAS adds a three (3)% subcontract handling expense to subcontract costs. Profit
or fee is not included.

8. Timely Payments to Subcontractor:

FAR 19.702 requires your company to establish and use procedures to ensure the
timely payment of amounts due pursuant to the terms of your subcontracts with
small, small disadvantages, and women-owned small business concerns.

State whether you company has established and uses such procedures.

CAS's standard payment terms for such size firms is Net 30 after approval of the
invoice.

9. Description of Good Faith Effort:

Maximum practicable utilization of small, small disadvantage, and women-owned
small business concerns as subcontractors in Government contracts is a matter of
national interest with both social and economic benefits. When a contractor
fails to make a good faith effort to comply with a subcontracting plan, these
objectives are not achieved, and 15 U.S.C. 637(d)(4)(F) directs that liquidated
damages shall be paid by the contractor. In order to demonstrate your compliance
with a good faith effort to achieve the small, small disadvantaged, and
women-owned small business subcontracting goals, outline the steps your company
plans to take. These steps will be negotiated with the Contracting Officer prior
to approval of the plan.:

CAS was a successful 8a contractor and is committed to helping similar firms and
will implement the plan and meet the goals. Normally our SDB/WO goals are based
on 10% of the actual awarded contract value. CAS is willing to put some portion
of our profits or fee at risk to assure the GSA that we will meet the goals.
