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

$8,800,000, then an amount equal to difference between $8,800,000 and the
Qualified Payment, if any, actually received by the Assignees; provided,
however, the value of any Net Proceeds not consisting of cash for which there is
not a readily available publicly recorded market value shall be determined by
the Assignees in their reasonable discretion based on good faith negotiations
with Assignor.

“Analytica Sale” means a sale, conveyance, transfer, assignment, license, lease
or other disposition of any interest in the stock and/or assets of Analytica.

“Assignment of Rights Under Royalty Agreement” means those certain Assignments

and/or any other consideration paid by the purchaser in connection with the
Analytica Sale, net of (a) customary and reasonable out-of-pocket cash costs,

(b) taxes paid or reasonably estimated to be payable as a result thereof, in
each case, as agreed to by Assignees.

2. Each Assignor hereby assigns to Assignees one hundred percent (100%) of the

Analytica to remit the Analytica Proceeds Amount upon the consummation of an

Assignees (the “Agent”), pursuant to the wire instructions set forth on Exhibit
A hereto. If any Assignor and/or any subsidiary or affiliate of Assignor
receives any Net Proceeds from an Analytica Sale prior to payment in full of the
Analytica Proceeds Amount to the Agent, such Assignor shall, and shall cause
such subsidiary or affiliate to, immediately deliver such Net Proceeds to the
Agent in precisely the form held by such Assignor or such subsidiary or
affiliate (except for any necessary endorsement) and until so delivered such Net
Proceeds shall be held in trust as the property of the Assignees.

4. Until payment in full of the Analytica Proceeds Amount to the Agent, each
Assignor hereby irrevocably authorizes and empowers each Assignee, (a) to ask,
demand, receive, receipt and give acquittance for any and all Net Proceeds which
may be or become due or payable, or remain unpaid at any time and times to such
Assignor, (b) to endorse any checks, drafts or other orders for the payment of
money payable to such Assignor in payment thereof, and (c) in such Assignee’s
discretion, to file any claims or take any action or institute any proceeding,
either in its own name or in the name of such Assignor or otherwise, which such
Assignee may deem necessary or advisable to effectuate the foregoing. It is
expressly understood and agreed, however, that no Assignee shall be required or
obligated in any manner to make any demand or to make any inquiry as to the
nature or sufficiency of any payment received by it, or to present or file any
claim or take any other action to collect or enforce the payment of any amounts
which may have been assigned to such Assignee or to which such Assignee may be
entitled hereunder at any time or times.
