CONVERTIBLE NOTES PAYABLE AND REVOLVING FINANCING AGREEMENT	15. CONVERTIBLE NOTES PAYABLE AND REVOLVING FINANCING AGREEMENT Convertible Notes from Carlyle On April 29, 2008, the Company issued and sold to the Investors a 5% Secured Convertible Promissory Note of $5,000,000 with an interest rate of 5% and maturity date of April 29, 2011. On April 29, 2009, CREG and the Investors amended and restated the 5% secured convertible promissory note. Accordingly, the Conversion Rights and Conversion Price were amended so that the holder of the Second Note had the right, but not the obligation, to convert all or any part of the outstanding principal amount of the Second Note, together with interest, into shares of the Company’s common stock, at any time on or after March 30, 2010 (or such earlier date if the audited consolidated financial statements of the Company for the fiscal year ending December 31, 2009 are available on a date prior to March 30, 2010) and prior to the maturity date (or such later date on which this Note is paid in full), at the following conversion price: (a) an amount equal to (i) the Company’s net profit, adjusted in accordance with the Second Note, multiplied by (ii) 5.5, and less (iii) the principal amount of the Second Note, together with accrued interest, divided by (b) the then total shares of the Company’s common stock outstanding on a fully-diluted basis. This note was considered to have a BCF starting from January 1, 2010 because the conversion price for this note was $1.154 as of April 29, 2011. Accordingly, the BCF of $3.15 million was recorded separately as unamortized BCF based on the intrinsic value method and the Second Note was recorded in the balance sheet at face value less the unamortized BCF. In June 2011, Carlyle converted the Second Note into 4,334,192 shares of the Company’s common stock at $1.154 per share. The effective date of the conversion was April 29, 2011. On April 29, 2009, CREG issued an 8% Secured Convertible Promissory Note of $3 million to CAGP with an original maturity date of April 29, 2012. The note holder has the right to convert all or any part of the outstanding principal amount of this note, together with interest, if any, into shares of the Company’s common stock, at any time on or after March 30, 2010 (or such earlier date if the audited consolidated financial statements of the Company for the fiscal year ending December 31, 2009 are available on a date prior to March 30, 2010) and prior to the maturity date (or such later date on which this note is paid in full), at a conversion price per share of common stock equal to $0.80. On May 11, 2012, Carlyle, Great Essential Investment, Ltd., (“Great Essential”) and the Company entered into a Convertible Promissory Note Transfer Agreement (the “Agreement”) dated April 28, 2012, in which Great Essential agreed to pay $3 million to Carlyle for its entire right, title and interest in the Note. All interest due and payable on the Note as of April 29, 2012 was paid by the Company to Carlyle. The transfer of the Note took effect after the payment of the $3 million transfer price and interest accrued after April 29, 2012 was paid in full by the Great Essential. In the Agreement, Carlyle and Great Essential agreed to extend the maturity date on the Note for 60 days following the effective date of the transfer. On July 24, 2012, Carlyle, Great Essential and the Company entered into a First Amendment to Convertible Promissory Note Transfer Agreement, effective June 30, 2012, in which all parties agreed to extend the termination date of the Agreement from June 30, 2012 to August 30, 2012, and the maturity date of the 8% Secured Promissory Note of $3,000,000, from July 28, 2012 to September 26, 2012. In September 2012, Great Essential paid Carlyle in full for the note, including accrued interest and, after the note was transferred to Great Essential, Great Essential converted the note into 3,750,000 shares of the Company’s common stock at $0.80 per share in accordance with the terms of the transfer agreement. Convertible Note and Loan Agreement with China Cinda and its Affiliate On August 18, 2010, the “Company and its wholly-owned subsidiaries Sifang, Shanghai TCH and Xi’an TCH entered into a Notes Purchase Agreement (the “Note Agreement”) with China Cinda (HK) Asset Management Co., Ltd, a company organized under the laws of the Hong Kong Special Administrative Region of China (“Cinda”). Under the terms of the Note Agreement, the Company will issue Cinda two tranches of convertible notes (the “Notes”), each having a principal amount equal to the US Dollar equivalent of RMB 50 million. Under the Note Agreement, the Notes shall be issued before August 18, 2011. The Notes have a three-year maturity date from the date of the issuance of the first tranche. The exchange rate between RMB and US Dollar for each issue of Notes is the middle rate published by the People’s Bank of China (the “PBOC”) for the second business day prior to each issuance. Each Note bears interest at a rate equal to that of PBOC base interest rate for the relevant interest period (the period commencing on and including January 1 of each year and ending on and including December 31 of such year) plus 2%. If Cinda does not convert or fully convert the Notes to shares prior to maturity, the Company will pay the difference between the interest rate described above and 18% on the outstanding amount. As collateral for the notes, Mr. Ku, CEO of the Company entered into a Share Pledge Agreement with Cinda on August 18, 2010, to pledge each 4,500,000 shares of the Company’s common stock held by him to secure the first Note and the second note before its issuance, respectively. Each Note has a conversion price at the lower of (i) $2.46 per share or (ii) an amount equal to the Company’s EPS based upon the consolidated earnings of the Company for 2010 on a weighted average fully diluted basis, multiplied by seven. The Notes will have a contingent BCF which will be recorded when the contingency is resolved. Also on August 18, 2010, Xi’an TCH and China Jingu International Trust Co. Ltd. (“Jingu”), an affiliate of Cinda also entered into a Capital Trust Loan Agreement (“Trust Loan Agreement”), in which Jingu will raise 100 million RMB under a Jingu CREG Recycling Economy No. 1 Collective Fund Trust Plan (“Trust Plan”) and lend such amount under the Trust Plan to Xi’an TCH (the “Loans”). If the Loans under the Trust Loan Agreement do not occur, then under the Note Agreement the principal amount of the Notes to be issued in each tranche will be the US dollar equivalent of RMB 100 million. In connection with the Trust Loan Agreement, the Company also entered into an Exchange Rights Agreement pursuant to which the Loans can be exchanged (on the same terms as the Notes can be converted) for shares of the Company’s common stock which can in turn be registered under the Registration Rights Agreement. All proceeds from the Notes and the Loans will be used to complete the Phases IV and V of the Erdos TCH Energy Saving Development Co., Ltd. (“Erdos TCH”) project. The term of the Loans is for three years from the date of the first draw. The interest rate for the Loans is the People’s Bank of China’s (“PBOC”) three year loan base interest rate plus two percent (2%). If the Loans are not exchanged for shares of the Common Stock of the Company as described below prior to maturity, Xi’an TCH will pay the difference between the interest rate described above and 18% on the outstanding amount. Under the Trust Loan Agreement and separate agreements entered by Jingu, Erdos TCH, Shanghai TCH, Xi’an TCH and Mr. Guohua Ku on August 18, 2010, Erdos TCH shall pledge the accounts receivable, equipment and assets of its Phases IV and V projects to Jingu as a guarantee to the Loans, Xi’an TCH shall pledge its 80% equity in Erdos TCH to Jingu as a guarantee to the Loans, Shanghai TCH shall provide a joint liability guarantee to Jingu for the Loans, and Mr. Guohua Ku shall provide his personal joint liability to Jingu for the Loans. On December 30, 2010, the Company received $7,533,391 (RMB 50,000,000) from the first tranche of the Loans. On January 30, 2011, the Company received another $7,533,391 (RMB 50,000,000) from the first tranche convertible Note. Under ASC 815 – Derivatives and Hedging, the FV of the conversion option is a derivative that was bifurcated and treated as liability at the date of inception. The conversion feature was accounted for at December 31, 2011 and 2010 using the conversion price of $2.46. The conversion feature is akin to a call option, therefore, the Black-Scholes option pricing model was used by using the maximum conversion price of $2.46 as the strike price. Since the conversion option is an embedded derivative and is bifurcated from the host contact, BCF analysis is not required. The FV of the conversion feature was recorded as a liability and will be marked to market until the conversion rate is set. As the loan has a reset clause in the event the Company issues shares below the conversion price, it will be treated as a liability as long as the loan is outstanding. The unamortized discount due to conversion feature will continue to be amortized over the term of the loan; during the year ended December 31, 2011, the Company amortized $10,747,493 due to BCF including the remaining unamortized portion as a result of repayment of the loans as described below. On December 9, 2011, the Company, Cinda and Mr. Guohua Ku, the Chairman, CEO and a major shareholder of the Company entered into a Supplemental Agreement (the “Supplemental Agreement”) to the Notes Purchase Agreement which was dated August 18, 2010. Pursuant to the terms of the Supplemental Agreement, the Company and Cinda terminated the transaction of the second tranche of RMB 50 million of the convertible note under the Note Agreement. The Company and Cinda also agreed that the Company will redeem the outstanding convertible note at the U.S. Dollar amount equivalent to RMB 25 million each on December 30, 2011 and November 30, 2012, respectively, plus accrued interest at 18% (the "Redemption Interest Rate") up to the applicable Redemption Date, minus any interest already accrued and paid (together with the Redemption Principal Amount, the "Redemption Price"). There was an additional 5% interest rate on any default in payment of the Redemption Price and due on demand. The interest on the Redemption Principal Amount due on November 30, 2012 (the "Second Redemption Principal Amount") accrued at 18%. Half of the amount owed was paid by the Company on June 20, 2012 and the remaining half was due on November 30, 2012; however, upon request from Cinda, the November 30, 2012 date was extended to a future date. Xi’an TCH redeemed $3.97 million (RMB 25 million) and interest of $1.13 million (RMB 7.14 million) on December 30, 2011 per the Supplemental Agreement described above. During the year ended December 31, 2012, the Company amortized $2,140,050 from the unamortized discount due to the conversion feature of the remaining RMB 25 million. As of December 31, 2012, there was no derivative liability as the Company redeemed half of the outstanding convertible notes at December 30, 2011 and will redeem the remaining half at a future date, plus accrued interest at 18%. During the year ended December 31, 2012, the Company recorded interest expense of $746,599 on the $3.97 million (the remaining RMB 25 million) of Cinda loan at 18%. The repayment of the Cinda loan for the remaining $3.97 million and unpaid interest of $383,939 was, upon request from Cinda and per an oral agreement, extended from November 30, 2012 to a future date. On December 9, 2011, Mr. Ku executed a Certificate for additional collateral to pledge an additional 1.5 million shares of common stock of the Company that he owns as collateral to Cinda to secure the unpaid note. In addition, on December 9, 2011, Xi’an TCH and Jingu, an affiliate of Cinda also entered into a Supplemental Agreement (the “Jingu Agreement”) to the Capital Trust Loan Agreement. Pursuant to the terms of the Jingu Agreement, Xi’an TCH repaid $7.94 million (RMB 50 million) and interest of $1.00 million (RMB 6.45 million) to Jingu on December 16, 2011.
