On February 13, 2014, the Board of Directors (the “Board”) of Aetrium Incorporated (the “Company”) authorized and declared a dividend distribution of one right (a “Right”) for each outstanding share of common stock, par value $0.001 per share (the “Common Shares”), of the Company to stockholders of record as of the close of business on February 24, 2014 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.001 per share (the “Preferred Shares”), of the Company at an exercise price of $30.00 per one one-thousandth of a Preferred Share, subject to adjustment (the “Exercise Price”). The complete terms of the Rights are set forth in a Tax Benefit Preservation Plan (the “Rights Plan”), dated as of February 13, 2014, between the Company and Computershare Trust Company, N.A., as rights agent.

By adopting the Rights Plan, the Board is helping to preserve the value of certain deferred tax benefits, including those generated by net operating losses (collectively, the “Tax Benefits”). The Company's ability to use these Tax Benefits would be substantially limited if it were to experience an “ownership change” as defined under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). In general, an ownership change would occur if there is a greater than 50-percentage point change in ownership of securities by stockholders owning (or deemed to own under Section 382 of the Code) five percent or more of a corporation's securities over a rolling three-year period. The Rights Plan reduces the likelihood that changes in the Company's investor base have the unintended effect of limiting the Company's use of its Tax Benefits. The Board believes it is in the best interest of the Company and its stockholders that the Company provide for the protection of the Tax Benefits by adopting the Plan.

The Rights Plan is intended to act as a deterrent to any person acquiring shares of the Company's securities equal to or exceeding the Trigger Amount (as defined below) without the approval of the Board. This would protect the Tax Benefits because changes in ownership by a person owning less than 4.99% of the Company's stock are not included in the calculation of “ownership change” for purposes of Section 382 of the Code. The Board has established procedures to consider requests to exempt certain acquisitions of the Company's securities from the Rights Plan if the Board determines that doing so would not limit or impair the availability of the Tax Benefits or is otherwise in the best interests of the Company.

The Rights Plan specifying the terms of the Rights (as defined below) and the text of the press release announcing the declaration of the Rights are incorporated herein by reference as exhibits to this current report. The following summary provides only a general description of the Rights Plan and is qualified in its entirety by reference to such exhibits.

The following is a summary of the terms of the Rights Plan. The summary does not purport to be complete and is qualified in its entirety by reference to the Rights Plan, a copy of which is attached as Exhibit 4.1 and incorporated herein by reference.

Distribution and Transfer of Rights; Rights Certificates

The Board has declared a dividend of one Right for each outstanding Common Share. Prior to the Distribution Date referred to below:

Rights will accompany any new Common Shares that are issued after the Record Date.

Distribution Date

Subject to certain exceptions specified in the Benefit Plan, the Rights will separate from the Common Shares and become exercisable following (i) the 10^th business day (or such later date as may be determined by the Board) after the public announcement that an Acquiring Person has acquired beneficial ownership of 4.99% or more of the Common Shares or (ii) the 10^th business day (or such later date as may be determined by the Board) after a person or group announces a tender or exchange offer that would result in ownership by a person or group of 4.99% or more of the Common Shares.

The date on which the Rights separate from the Common Shares and become exercisable is referred to as the “Distribution Date.”

After the Distribution Date, the Company will mail Rights certificates to the Company's stockholders as of the close of business on the Distribution Date and the Rights will become transferable apart from the Common Shares. Thereafter, such Rights certificates alone will represent the Rights.

Preferred Shares Purchasable Upon Exercise of Rights

After the Distribution Date, each Right will entitle the holder to purchase, for $30.00 (the “Exercise Price”), one one-thousandth of a Preferred Share having economic and other terms similar to that of one Common Share. This portion of a Preferred Share is intended to give the stockholder approximately the same dividend, voting and liquidation rights as would one Common Share, and should approximate the value of one Common Share.

More specifically, each one one-thousandth of a Preferred Share, if issued, will:

Flip-In Trigger

If a person or group of affiliated or associated persons (an “Acquiring Person”) obtains beneficial ownership of 4.99% or more of the Common Shares, except pursuant to an offer for all outstanding Common Shares that the independent members of the Board determine to be fair and not inadequate and to otherwise be in the best interests of the Company and its stockholders after receiving advice from one or more investment banking firms, then each Right will entitle the holder thereof to purchase, for the Exercise Price, a number of Common Shares (or, in certain circumstances, cash, property or other securities of the Company) having a then-current market value of twice the Exercise Price. However, the Rights are not exercisable following the occurrence of the foregoing event until such time as the Rights are no longer redeemable by the Company, as further described below.

Following the occurrence of an event set forth in preceding paragraph, all Rights that are or, under certain circumstances specified in the Benefit Plan, were beneficially owned by an Acquiring Person or certain of its transferees will be null and void.

Any person who, together with its affiliates and associates, beneficially owns 4.99% or more of the outstanding Common Shares as of the time of the first public announcement of the Benefit Plan (an “Exempt Person”) shall not be deemed an Acquiring Person, but only for so long as such person, together with its affiliates and associates, does not become the beneficial owner of any additional Common Shares while such person is an Exempt Person. A person will cease to be an Exempt Person if such person, together with such person's affiliates and associates, becomes the beneficial owner of less than 4.99% of the outstanding Common Shares.

Flip-Over Trigger

If, after an Acquiring Person obtains 4.99% or more of the Common Shares, (i) the Company merges into another entity, (ii) an acquiring entity merges into the Company or (iii) the Company sells or transfers more than 50% of its assets, cash flow or earning power, then each Right (except for Rights that have previously been voided as set forth above) will entitle the holder thereof to purchase, for the Exercise Price, a number of shares of common stock of the person engaging in the transaction having a then-current market value of twice the Exercise Price.

Redemption of the Rights

The Rights will be redeemable at the Company's option for $0.001 per Right (payable in cash, Common Shares or other consideration deemed appropriate by the Board) at any time on or prior to the 10th business day (or such later date as may be determined by the Board) after the public announcement that an Acquiring Person has acquired beneficial ownership of 4.99% or more of the Common Shares. Immediately upon the action of the Board ordering redemption, the Rights will terminate and the only right of the holders of the Rights will be to receive the $0.001 redemption price. The redemption price will be adjusted if the Company undertakes a stock dividend or a stock split.

Exchange Provision

At any time after the date on which an Acquiring Person beneficially owns 4.99% or more of the Common Shares and prior to the acquisition by the Acquiring Person of 50% of the Common Shares, the Board may exchange the Rights (except for Rights that have previously been voided as set forth above), in whole or in part, for Common Shares at an exchange ratio of one Common Share per Right (subject to adjustment). In certain circumstances, the Company may elect to exchange the Rights for cash or other securities of the Company having a value approximately equal to one Common Share. 

Expiration of the Rights

The Rights expire on the earliest of (i) 5:00 p.m., New York time, on the date that the votes of the stockholders of the Company, with respect to the Company's 2014 Annual Meeting of Stockholders are certified, unless the continuation of the Rights is approved by the affirmative vote of the majority of shares of Common Stock present in person or represented by proxy and voting on such matter at the Company's 2014 Annual Meeting of Stockholders (or any adjournment or postponement thereof) duly held in accordance with the Company's Bylaws and applicable law; (ii) 5:00 p.m., New York time, on February 13, 2017; (iii) the time at which the Rights are redeemed or exchanged under the Plan; (iv) the repeal of Section 382 or any successor status and the Board's determination that the Plan is no longer necessary for preservation of the Company's NOLs; or (v) the beginning of a taxable year of the Company to which the Board determines that no NOLs may be carried forward.

Amendment of Terms of Rights Plan and Rights

The terms of the Rights and the Benefit Plan may be amended in any respect without the consent of the holders of the Rights on or prior to the Distribution Date. Thereafter, the terms of the Rights and the Benefit Plan may be amended without the consent of the holders of Rights in order to (i) cure any ambiguities, (ii) shorten or lengthen any time period pursuant to the Benefit Plan or (iii) make changes that do not adversely affect the interests of holders of the Rights.

Voting Rights; Other Shareholder Rights

The Rights will not have any voting rights. Until a Right is exercised, the holder thereof, as such, will have no separate rights as a shareholder of the Company.

Anti-Dilution Provisions

The Board may adjust the Exercise Price, the number of Preferred Shares issuable and the number of outstanding Rights to prevent dilution that may occur from a stock dividend, a stock split or a reclassification of the Preferred Shares or Common Shares.

With certain exceptions, no adjustments to the Exercise Price will be made until the cumulative adjustments amount to at least 1% of the Exercise Price. No fractional Preferred Shares will be issued and, in lieu thereof, an adjustment in cash will be made based on the current market price of the Preferred Shares.

Taxes

The distribution of Rights should not be taxable for federal income tax purposes. However, following an event that renders the Rights exercisable or upon redemption of the Rights, shareholders may recognize taxable income.
