                                     III.
                             COSTS AND EFFICIENCY

     (a)  The cost to the DEPARTMENT for the services to be provided by the
CONTRACTOR under the Contract shall not exceed Eighteen Million One Hundred
Thirty-Two Thousand One Hundred Sixty-One Dollars ($  18,132,161.00  ).
     (b)  Method of Payment: Payments by the DEPARTMENT shall be made within 30
days of receipt of an expenditure report or an approved invoice from the
CONTRACTOR.

     Charges for late payment of invoices other than as prescribed by Title 15,
Subtitle 1, of the State Finance and Procurement Article, Annotated Code of
Maryland, as from time to time amended, are prohibited.

     In addition to any other available remedies if, in the opinion of the
Procurement Officer, the CONTRACTOR fails to perform in a satisfactory and
timely manner, the Procurement Officer may refuse or limit approval of any
invoice for payment, and may cause payments to the CONTRACTOR to be reduced or
withheld until such time as the CONTRACTOR meets performance standards as
established by the Procurement Officer.

     (c)  Availability of Funding: Payment of these funds is conditional upon
the DEPARTMENT receiving funds as specified to pay for the total cost of the
services set forth in the Appendix from Department of Health and Human Services
and State General Funds.

     If the General Assembly fails to appropriate funds or if funds are not
otherwise made available for continued performance for any fiscal period of this
contract succeeding the first fiscal period, this Contract shall be cancelled
automatically as of the beginning of the fiscal year for which funds were not
appropriated or otherwise made available; provided; however, that this will not
affect either the State's rights or the CONTRACTOR's rights under any
termination clause in the Contract.  The effect of termination of the Contract
hereunder will be to discharge both the CONTRACTOR and the DEPARTMENT from
future performance of the Contract, if not from their rights and obligations
existing at the time of termination.  The CONTRACTOR shall be reimbursed for the
reasonable value of any nonrecurring cost incurred but not amortized in the
price of the Contract.  The State shall notify the CONTRACTOR as soon as it has
knowledge that funds may not be available for the continuation of this contract
for each succeeding fiscal period beyond the first.

     If the General Assembly fails to appropriate sufficient funds or if
sufficient funds are not otherwise made available for performance of this
Contract, the DEPARTMENT reserves the right in its sole discretion to reduce the
total amount of funding under the Contract.

     (d)  The CONTRACTOR'S Federal Tax Identification Number is 94-3145844. The
CONTRACTOR agrees to include this number on all invoices billed to the
DEPARTMENT. The DEPARTMENT may withhold payment for failure to comply with this
provision.

     The CONTRACTOR's Social Security Number is ________________________________
(individual contractor only).

regulations, as it was prior to said amendment.

     Adjustments of funds between categories approved in writing by the Project

discriminate in any manner against an employee or applicant for employment
because of race, color, religion, creed, age, sex, marital status, national

<PAGE>

     The CONTRACTOR agrees further to not utilize criteria or methods of
administration that have the effect of subjecting anyone to discrimination on

substantially impairing accomplishment of the objectives of the Department of
Human Resources program with respect to individuals with disabilities.

     (k)  Subcontracting; Assignment: The CONTRACTOR may not subcontract any
portion of the services provided under the Contract without obtaining the prior

protect the interest of the State. The Department shall not be responsible for
the fulfillment of the CONTRACTOR's obligation to the subcontractors.

     (l)  Termination for Convenience: The performance of work under this
Contract may be terminated by the DEPARTMENT in accordance with this clause in
whole, or from time to time in part, whenever the DEPARTMENT shall determine
that such termination is in the best interest of the State. The DEPARTMENT will
pay all reasonable costs associated with this Contract that the CONTRACTOR has
incurred up to the date of termination and all reasonable costs associated with
termination of the Contract; provided, however, that the CONTRACTOR shall not be
reimbursed for any anticipatory profits which have not been earned up to the
date of termination. Termination hereunder, including the determination of the
rights and obligations of the parties, shall be governed by the provisions of
COMAR 21.07.01.12A(2).

     (m)  Termination for Cause: If the CONTRACTOR fails to fulfill its
obligations under this Contract properly and on time, or otherwise violates any

Officer its written claim containing the information specified in COMAR

inaccurate, incomplete, or not current.

     (y)  Liability for Loss of Data: In the event of loss of any data or
records necessary for the performance of this Contract where such loss is due to

          (1)  CONTRACTOR shall obtain written approval of the DEPARTMENT for
any purchase of assets with funds paid under this Contract, excluding ordinary
office supplies, except that such is not required with regard to purchase of
assets described in the Appendix attached hereto.

          (2)  Title to all property furnished by the DEPARTMENT shall remain in
the DEPARTMENT. Title to all property acquired by the CONTRACTOR at a cost of

cost of the work covered by the Contract, or shall otherwise reimburse the
DEPARTMENT as directed by the DEPARTMENT.

          (iv)   source of the property;
          (v)    percentage of Federal funds used in acquisition of the
                 property; and
          (vi)   location, use and condition of the property.

     (7)  Upon termination of the Contract, the DEPARTMENT may require the
CONTRACTOR to deliver to the DEPARTMENT any property specifically produced or
acquired for the performance of this Contract.

IRS depreciation schedules.

  (aa) The CONTRACTOR, if providing direct services to the DEPARTMENT'S clients,
agrees to include an acknowledgment of funding received from the DEPARTMENT
under this contract in any and all related publications. "Related publications"
are not limited to publications funded under the contract.

  Prohibition against shifting Maryland income to out-of-state affiliates.

trade names, or other intangible property associated with Contractor.
Contractor agrees that during the course of this Contract it shall not make any
royalty or similar payments to any affiliated company; and if any such royalty
or similar payments are made, Contractor and the affiliated company shall file

taxes in such a manner that Contractor does not claim a deduction against
Maryland income tax for such paymnts, and the affiliated company receiving the
royalty or similar payments files Maryland income tax returns and pays Maryland
tax, under a formula that reasonably apportions the income of the affiliated
company among the states, including Maryland, in which the Contractor does
business.  Contractor agrees that it is authorized to bind its affiliated
entities to the terms hereof.

  This Contract, together with the Appendix attached hereto and incorporated
herein by reference, represents the complete, total and final understanding of
