         WHEREAS, in accordance with Security Agreement, Avanti pledged all of

Obligation. Avanti (a) consents to the valuation of the Collateral set forth on

satisfaction of the Loan Principal Obligations, and (b) agrees that the Loan
Other Obligations remain outstanding.

If there is a discrepancy on the asset list between Schedule 3 and Schedule 4;
Schedule 4 will supercede and have rights over Schedule 3.

to accept, in full satisfaction of the Loan Other Obligation, assignment to
CyberOptics of the equipment set forth in the attached Schedule 3 (the
"Equipment"), plus the sum in cash that remains in the accounts of Avanti at the
Termination Date, assuming that Avanti has made no further distributions or
payments except payment of the February Rent, as defined below, or in payment of
Other Obligations together totaling not more than $77,000 and assuming the

                            II. THE LEASE OBLIGATIONS

         2.1 Settlement. The Sublessor hereby agrees to accept, in full
satisfaction of any and all Lease Obligations, (i) the February Rent when the
same is due and payable in the amount of $23,000 (the "February Rent"), plus
(ii) the sum of $38,500 (the "Termination Payment") in cash paid on or before
the Termination Date, plus (iii) the Security Deposit under the Sublease, plus
(iv) an assignment to the Sublessor of those certain furniture, fixtures and

hereby sells, assigns and transfers to Sublessor, effective as of the
Termination Date, all of its right, title and interest in the FF&E, free of any
liens, claims or encumbrances of any kind. Sublessor agrees that Avanti shall
