The Company paid down the principal of the Kien Huat Note in the amount of approximately $17.6 million from the proceeds of the rights offering the Company consummated in May 2011. The maturity date for the Kien Huat Note was May 17, 2013. On August 8, 2012, the Company and Kien Huat entered into Amendment No. 1 (the “Amendment”) to the Loan Agreement. Pursuant to the Amendment, the maturity date of the Kien Huat Note was extended from May 17, 2013 to December 31, 2014. In consideration of the extension of the maturity date of the Kien Huat Note, effective as of date of the Amendment, the rate of interest was amended to be 7.5% per annum in place of 5% per annum. In addition, the Company paid Kien Huat a one-time fee of $174,261, or 1% of the outstanding principal amount of the Loan upon execution of the Amendment. On December 18, 2013, the Company and Kien Huat entered into Amendment No. 2 (the “Second Amendment”) to the Loan Agreement. Pursuant to the Second Amendment, the maturity date of the Kien Huat Note was extended from December 31, 2014 to March 15, 2015. In consideration of the extension of the maturity date of the Kien Huat Note, the Company paid Kien Huat a one-time fee of $25,000 upon execution of the Second Amendment. In addition, the Company agreed to pay the out-of-pocket legal fees and expenses incurred by Kien Huat in an amount not to exceed $20,000. Except for these amendments, the Loan Agreement remains unchanged and in full force and effect. Subject to and upon compliance with the provisions of the Loan Agreement, including the receipt of shareholder approval of the issuance of the Company's common stock upon conversion of the Kien Huat Note (the "Shareholder Approval"), Kien Huat has the right to convert all or any portion of the principal sum evidenced by the Kien Huat Note such that the unconverted portion is $1,000 or a multiple of $1.00 in excess thereof into fully paid and non-assessable shares of Empire’s common stock at a conversion rate of initially 377 shares of common stock per $1,000 in principal amount, which represents a conversion price of approximately $2.65 per share, subject to adjustment in accordance with the Loan Agreement. If, as of any date during the term (the “Measuring Date”), the average of the last reported bid prices of the Company’s common stock for the 20 days consecutive trading days as defined in the Loan Agreement, ending on the trading day prior to the Measuring Date exceeds 200% of the conversion price in effect on the Measuring Date, then the Company is entitled to elect that Kien Huat convert all of the principal sum evidenced by the Kien Huat Note into shares of its common stock in accordance with the terms and provisions of the Loan Agreement, including the receipt of the Shareholder Approval. If Empire does not elect to force conversion of the Kien Huat Note and there have been no events of default as defined in the Loan Agreement, Empire may voluntarily prepay the Loan in whole or in part, with all interest accrued through the applicable period, absent notice from Kien Huat of its election to convert the Kien Huat Note. In the event the Conversion Conditions are met,the Kien Huat Note will be converted into shares of the Company's common stock upon the earlier of (i) the consummation of a rights offering pursuant to the terms of that certain Commitment Letter (which is discussed in Note A above) and (ii) the maturity date of March 15, 2015. In the event the Kien Huat Note is converted in common stock pursuant to the Commitment Letter, the Kien Huat Note would be convertible into shares of common stock of the Company at a conversion rate of 382.202837 shares of common stock per $1,000 in principal amount, which represents a conversion price of approximately $2.6164 per share. Such conversion rate and conversion price reflect adjustments to these terms that are required by the terms of the Loan Agreement as a result of the April 2013 Rights Offering (as defined below) and the April 2014 Rights Offering. The conversion rate and conversion price are subject to further adjustment pursuant to the Loan Agreement in the event of certain dilutive issuances by the Company. In the event the Conversion Conditions are not met, we anticipate refinancing or extending the term of the Kien Huat Note prior to its maturity. However, there can be no assurance that the Company will be successful in refinancing the Kien Huat Note or amending its terms. If the Company is unable to refinance or amend the Kien Huat Note prior to its maturity, it could have a material adverse affect on the Company. On July 18, 2014, the holders of a majority of the voting power of the Company's voting securities acted by written consent to approve the issuance of shares of the Company's common stock upon the conversion of the Kien Huat Note. Pursuant to the Delaware General Corporation Law and the Securities Exchange Act of 1934, as amended, such action will be effective on September 11, 2014, which is at least 40 days after the mailing of notice of such action to the remaining holders of the Company's voting securities. The Company recognized approximately $653,000 and $657,000 in interest expense associated with the Loan during the six months ended June 30, 2014 and 2013, respectively. We have paid interest to Kien Huat pursuant to the Loan Agreement totaling approximately $4.1 million from November 2010 through March 31, 2014. Due to an inadvertent oversight, the Company did not withhold taxes due on such interest payments to Kien Huat, which is a foreign entity affiliate of ours, as required by the Internal Revenue Code of 1986, as amended. Kien Huat has reimbursed the Company for the taxes that were due on such interest payments, which are equal to 30% of the interest paid to Kien Huat, or approximately $1.2 million (the “Taxes Payable”). The Taxes Payable amount has been remitted to the Internal Revenue Service (the "IRS"). The interest on the Taxes Payable which is estimated in the amount of $119,000, will be remitted to the IRS upon the IRS's request therefor. The total of the Taxes Payable and interest thereon is approximately $1.3 million. Based on the Company’s actions to correct such oversight, the Company believes that it is not probable that penalties would be due; however, if penalties were to be due to the IRS, the amount could be up to approximately $450,000. The Company has not adjusted its historical financial statements for any period prior to March 31, 2014 as the Company believes that the impact to previously issued financial statements is not material.
