THE PROPOSAL

APPROVAL OF AN AMENDMENT TO THE THIRD AMENDED AND RESTATED ARTICLESOF INCORPORATION TO EFFECT A REVERSE STOCK SPLIT OF THE ISSUED ANDOUTSTANDING COMMON SHARES AT A RATIO RANGING FROM ONE-FOR-THREE TO ONE-FOR-TEN

General

The Board believes that it is in the best interest of the Company and the shareholders and is hereby soliciting shareholder approval of an amendment (the "Amendment") to the Company's Third Amended and Restated Articles of Incorporation to effect a reverse stock split of the Company's issued and outstanding Common Shares at a ratio of not less than one-for-three and not more than one-for-ten. A vote FOR the Proposal will constitute approval of the Amendment providing for the combination of any number of shares of the Company's issued and outstanding Common Shares between and including three and ten into one share of Common Shares and will grant the Board the authority to select which of the approved exchange ratios within that range will be implemented. If the shareholders approve this proposal, the Board will have the authority, but not the obligation, in its sole discretion, and without further action on the part of the shareholders, to select one of the approved reverse stock split ratios and effect the approved reverse stock split by filing the Amendment with the Registrar of Corporations of the Republic of the Marshall Islands at any time after the approval of the Amendment. If implemented, the reverse stock split will become effective as of the beginning of the business day after the filing of the Amendment with the Registrar of Corporations of the Republic of the Marshall Islands.

The Board believes that shareholder approval of an exchange ratio range (rather than an exact exchange ratio) provides the Board with maximum flexibility to achieve the purposes of the reverse stock split. If shareholders approve the Proposal the reverse stock split will be effected, if at all, only upon a determination by the Board that the reverse stock split is in the Company's and the shareholders' best interests at that time. In connection with any determination to effect the reverse stock split, the Board will set the time for such a split and select a specific exchange ratio within the range. These determinations will be made by the Board with the intention to create the greatest marketability of the Company's Common Shares based upon prevailing market conditions at that time.

The Board reserves its right to elect not to proceed, and abandon, the reverse stock split if it determines, in its sole discretion, that implementing this proposal is not in the best interests of the Company and its shareholders.

Purpose and Background of Reverse Stock Split

The purpose of the reverse stock split is to increase the per share trading price of the Company's Common Shares so that the Company may continue to comply with the minimum bid price of $1.00 per share listing requirement for listing the Company's Common Shares on Nasdaq. Nasdaq has several listing criteria that companies must satisfy in order to maintain their listing. One of these criteria is that the Company's Common Shares have a minimum closing bid price that is greater than or equal to $1.00 per share, and if the Company fails to maintain such $1.00 minimum closing bid price for a period of 30 consecutive business days, under Nasdaq rules, the Company would have to regain compliance during the applicable grace period. As of November 24, 2015, the Company's closing share price has been below $1.00 for three consecutive business days and the Company believes that effecting a reverse stock split would help the Company to continue to comply with the closing minimum bid price of $1.00 per share listing requirement for listing its Common Shares on Nasdaq. The Company risks having its shares delisted from Nasdaq if it fails to comply with this rule. In addition, the Company believes that a numberof institutional investors and investment funds are reluctant to invest, and in some cases may be prohibited from investing, in lower-priced stocks and that brokerage firms are reluctant to recommend lower-priced stocks to their clients. By effecting a reverse stock split, the Company believes it may be able to raise its Common Share price to a level where its Common Shares could be viewed more favorably by potential investors.

Other investors may also be dissuaded from purchasing lower-priced stocks because the brokerage commissions, as a percentage of the total transaction, tend to be higher for lower-priced stocks. A higher stock price after a reverse stock split could alleviate this concern.

The combination of continuing to be listed on Nasdaq and the lower transaction costs and increased interest from institutional investors and investment funds could have the effect of improving the trading liquidity of the Company's Common Shares.

The Board intends to effect the proposed reverse stock split only if it believes that a decrease in the number of Common Shares outstanding is likely to improve the trading price for the Company's Common Shares, and only if the implementation of a reverse stock split is determined by the Board to be in the best interests of the Company and its shareholders. There can be no assurance that the reverse stock split, if implemented, will achieve any of the desired results. There also can be no assurance that the Company will be successful in maintaining compliance with Nasdaq requirements or that the price per share of the Company's Common Shares immediately after the reverse stock split, if implemented, will increase proportionately with the reverse stock split, or that any increase will be sustained for any period of time.

Procedure for Exchange of Stock Certificates

As soon as practicable after the effective date of the reverse stock split, shareholders holding Common Shares in physical certificate form will be sent a letter of transmittal from the Company notifying them that the reverse stock split has been effected. The letter of transmittal will contain instructions on how shareholders should surrender to the Company's exchange agent certificates representing pre-split shares in exchange for certificates representing post-split shares. The Company expects that its transfer agent will act as its exchange agent for purposes of implementing the exchange of share certificates. No new certificates will be issued to a shareholder until such shareholder has surrendered such shareholder's outstanding certificate(s) together with the properly completed and executed letter of transmittal to the exchange agent. Any pre-split shares submitted for transfer, whether pursuant to a sale or other disposition, or otherwise, will automatically be exchanged for post-split shares.

SHAREHOLDERS SHOULD NOT DESTROY ANY SHARE CERTIFICATE(S) AND SHOULD NOT SUBMIT ANY CERTIFICATE(S) UNTIL REQUESTED TO DO SO.

Shareholders holding shares in book-entry form with the transfer agent need not take any action to receive post-split shares or cash payment in lieu of any fractional share interest, if applicable. If a shareholder is entitled to post-split shares, a transaction statement will automatically be sent to the shareholder's address of record indicating the number of Common Shares held following the reverse stock split.

Upon the reverse stock split, the Company intends to treat shares held by shareholders in "street name" through a bank, broker or other nominee in the same manner as registered shareholders whose shares are registered in their names. Banks, brokers or other nominees will be instructed to effect the reverse stock split for their beneficial holders holding shares in "street name." However, these banks, brokers or other nominees may have different procedures than registered shareholders for processing the reverse stock split and making payment for fractional shares. If a shareholder holds shares with a bank, broker or other nominee and has any questions in this regard, shareholders are encouraged to contact their bank, broker or other nominee.

Fractional Shares

No fractional shares will be created or issued in connection with the reverse stock split. Shareholders of record who otherwise would be entitled to receive fractional shares because they hold a number of pre-split shares not evenly divisible by the number of pre-split shares for which each post-split share is to be exchanged, will be entitled, upon surrender to the exchange agent of certificates representing such shares or, in the case of non-certificated shares, such proof of ownership as required by the exchange agent, to a cash payment in lieu thereof at a price equal to the fraction to which the stockholder would otherwise be entitled multiplied by the closing price of the common stock on Nasdaq on the last trading day prior to the effective date of the split as adjusted for the reverse stock split as appropriate or, if such price is not available, a price determined by the Board. The ownership of a fractional interest will not give the holder thereof any voting, dividend or other rights except to receive payment thereof as described herein.

Required Vote. Adoption of the Proposal requires the affirmative vote of a majority of the outstanding shares entitled to vote thereon.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR APPROVAL OF THE REVERSE STOCK SPLIT OF THE ISSUED AND OUTSTANDING COMMON SHARES AT A RATIO RANGING FROM ONE-FOR-THREE TO ONE-FOR-TEN. UNLESS REVOKED AS PROVIDED ABOVE, PROXIES RECEIVED BY MANAGEMENT WILL BE VOTED IN FAVOR OF SUCH APPROVAL UNLESS A CONTRARY VOTE IS SPECIFIED.

SOLICITATION

The cost of preparing and soliciting proxies will be borne by the Company. Solicitation will be made primarily by mail, but shareholders may be solicited by telephone, e-mail, or personal contact. The Board has retained Advantage Proxy as proxy solicitor in connection with the Special Meeting. If you have any questions or need assistance in voting your proxy, please contact Advantage Proxy at the number or email address listed below.

EFFECT OF ABSTENTIONS

An "abstention" occurs when a shareholder sends in a proxy with explicit instructions to decline to vote regarding a particular matter (other than the election of Directors for which the choice is limited to "for" or "withhold"). Abstentions are counted as present for purposes of determining a quorum. Abstentions will not be counted in determining whether the Proposal has been approved.

OTHER MATTERS

No other matters are expected to be presented for action at the Special Meeting. Should any additional matter come before the Special Meeting, it is intended that proxies in the accompanying form will be voted in accordance with the judgment of the person or persons named in the proxy.
