This is known as a blanket lien.

If a subordination agreement is not made between the SBA lender and the leasing company, the SBA lender has a right to cover the leased assets until the blanket lien is satisfied.

For example, if you lease some equipment, the leasing company may do one of two things: (1) file its own UCC-1 form with the understanding that it is already a blanket lien or (2) establish a subordination agreement with the SBA lender that essentially allows the leasing company to recover its assets.
