Exhibit 10.20

ASSIGNMENT AGREEMENT

This Agreement (the or this “Agreement”) is made as of January 20, 2004, between Littlefeet, Inc., a California corporation (“Littlefeet”) and Aetrium Incorporated, a Minnesota corporation (“Aetrium”), jointly (the “Parties”).

RECITALS:

A. The Parties entered into an Assignment and Assumption of Lease Agreement (the “Lease Assignment”) dated August 8, 2000 under which Aetrium assigned to Littlefeet that certain Standard Industrial/Commercial Single-Tenant Lease-Net dated September 18, 1998 by and between Aetrium and Pomerado Leasing No. 5 LP, a California limited partnership (“Lessor”), as successor in interest to W.H. Pomerado LLC, a California limited liability company (including Addendum to Lease dated September 17, 1998 (“Addendum”) and as amended by that certain First Amendment to Lease (“First Amendment”) dated September 10, 1999 and by that certain Consent to Assignment of Lease and Amendment of Lease dated August 10, 2000 by and among Lessor, Aetrium and Littlefeet (“First Consent”)) (“Lease”) respecting premises located at 13000 Gregg Street, Poway, California (the “Premises”). Aetrium remained liable for the full performance of lessee under the Lease. True and correct copies of the Lease Assignment and Lease are attached as Exhibit “A” and Exhibit “B” hereto, respectively. Any words or phrases defined in the Lease will have the same meaning and effect when used in this Agreement, unless otherwise expressly provided in this Agreement.

B. The term of the Lease is scheduled to expire on January 31, 2010 (the “Contractual Termination Date”).

C. Aetrium holds a security deposit in the amount of $67,500.00 (“Aetrium Security Deposit”) and Lessor holds a security deposit in the amount of $67,582.00 (the “Pomerado Security Deposit” the Aetrium Security Deposit and the Pomerado Security Deposit are collectively referred to as the “Security Deposits”).

D. Littlefeet will be ceasing operations in the near future and may be liable for substantial damages for rent and other sums that would have been payable through the balance of the Lease term. Littlefeet has requested that, in lieu of prosecuting a lawsuit against Littlefeet for such damages and for collection thereof, Aetrium instead assume the Lease and accept a one-time lump sum payment as set forth herein. Littlefeet acknowledges that such a reduction of its liability to Lessor and Aetrium is a substantial benefit to it in that, among other things, it reduces the absolute number of dollars it would otherwise have to pay to Lessor and Aetrium.

NOW, THEREFORE, in furtherance of the foregoing, and in consideration of the premises and the mutual covenants set forth below and other good and valuable consideration the receipt and adequacy of which is acknowledged, the Parties agree as follows:

In furtherance of the intentions set forth herein, each of the parties acknowledges that it is familiar with Section 1542 of the Civil Code of the State of California which provides as follows:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.”

Aetrium, with respect to Aetrium Released Matters, and Littlefeet, with respect to Littlefeet Released Matters, each hereby waives and relinquishes any right or benefit which it has or may have under Section 1542 of the Civil Code of the State of California or any similar provision of the statutory or nonstatutory law of any other jurisdiction, to the full extent that it may lawfully waive all such rights and benefits.

     4. Sublease. Aetrium hereby subleases to Littlefeet and Littlefeet hereby subleases from Aetrium that portion of the Premises not subject to the Tandberg Sublease (the “Subleased Premises”). Littlefeet accepts the Subleased Premises “as is.” All terms and conditions in the Lease as they pertain to the Subleased Premises are incorporated herein, except as otherwise set forth herein, as terms and conditions of this sublease (with each reference therein to Lessor and Lessee to be deemed to refer to Aetrium as sublessor and Littlefeet as sublessee) and, along with the further provisions of this Section 4, will be the complete terms and conditions of this sublease.
