MISDIRECTED INVOICE/ASSIGNMENT OF INVOICE/BILL OF SALE

relating to

all Lease Schedules now or hereafter attached to and made a part of Master Lease No. CML-3861A,

by and between

CELTIC LEASING CORP., as Lessor,

and

Exagen Diagnostics, Inc., as Lessee (the “Lease”)

This is to acknowledge that for all items of equipment now or hereafter subject to the above-referenced Lease Schedules (the “Equipment”), it has been and is since prior to delivery of said Equipment, the intent of Lessee to lease the Equipment from Lessor. However, certain vendor(s) may inadvertently misdirect invoicing to Lessee for the Equipment, instead of to Lessor. Any such misdirected invoice(s) will be paid by Lessor (unless clearly documented otherwise). Lessee hereby acknowledges that it is not its intention to acquire any rights, title or interest in any of the Equipment (except for those rights and interests granted under the Lease), and, therefore, for valuable consideration, receipt of which is hereby acknowledged, Lessee hereby assigns, sets over, and transfers to Lessor any and all rights, title and interest it may inadvertently acquire to the Equipment as a result of any such misdirected invoice(s). Upon payment of these misdirected invoice(s) by Lessor (and/or its Assignee), Lessee acknowledges that Lessor shall acquire free and clear title to the subject Equipment.
