          2.4  Earnout Payment. Buyer agrees to pay to Seller certain Earnout

Payments in consideration for the transfer of Acquired Assets. Seller may earn
consideration ("Earnout") in the form of annual earnout payments (each an

Earnout Period. The Earnout Payments shall be payable to Seller within 120 days

<PAGE>

     (c) In the event of a sale of a material amount but not all or
substantially all of the assets that generate FR Revenue, or a material purchase
of assets that generate FR Revenue, Buyer and Seller shall agree on a reasonable
adjustment to the Earnout, including, where appropriate, reasonable guidelines
for determining the calculations of FR Revenue relating to the change in assets,
to reflect the change in projected Earnout Payments and to reflect the third
party costs and royalty payments, if any, associated with any such purchase of
assets.

     (d) If Seller disputes Buyer's determination of any Earnout calculation, it
shall notify Buyer in writing within thirty (30) days of its receipt of the
Buyer's determination. In the event of such a dispute, including any disputes
concerning the reasonableness of proposed adjustments to the Earnout, Seller and
Buyer shall first use their best efforts to resolve the dispute. If the dispute
cannot be resolved within ten (10) days, it shall be submitted to an independent
public accounting firm on which the Parties mutually agree (the "Accountant")
                                                                 ----------
for resolution. Within 30 days after submission of the dispute, the Accountant
shall determine the Earnout calculation in accordance with this Agreement. The
Accountant's determination shall be final and binding upon the Parties, and the

further action is necessary or desirable to effectively transfer and assign to,

shall not otherwise have any rights to or interest in the LAU SECURITY SYSTEMS
mark.

         8.3  Audit Rights. During the Earnout Period, on an annual basis at
              ------------
Seller's expense, at mutually agreeable times, Seller or its agent or
representative will be provided reasonable access during normal business hours
to Buyer's books and records relating to FR Revenue for purposes of inspecting
and auditing books and records relating to the Earnout provided for in this
Agreement.

Buyer retains the right, in its sole discretion, to exercise any of its rights
or remedies under the License.

         8.5  Consents. Seller shall use reasonable speed and effort to

requirements as specified in Section 4.3 above, including, without limitation,
the consent required under the license agreement between Facia Reco Associates
and Seller and under the TSWG contract between the Department of Defense and
Seller, within a reasonable period after the Closing Date. Until required third
party approvals are obtained, Seller agrees to hold any assets, including
Contracts, included in the Acquired Assets that require such approval on behalf
of, at the direction of, and for the benefit of Buyer. Any asset, including the
Contracts, that would otherwise be included in the Acquired Assets but the
assignment or attempted assignment of which would be invalid or would constitute
a breach of contract, shall be held and/or received by Seller for the use and at
the direction and for the benefit of Buyer, provided that Seller shall be
responsible for ensuring that the benefits of and burdens under such Contracts
shall flow to the Buyer.
