10% Convertible Notes Payable

On November 5, 2014, the Company entered into a Convertible Note and Warrant Purchase Agreement (the “Purchase Agreement”) with various accredited, non-affiliated investors (each, a “Purchaser”), pursuant to which the Company sold an aggregate principal amount of $238,500 of its (i) 10% Convertible Notes due September 15, 2015 (each a “Note”, and together, the “Notes”) and (ii) Warrants to purchase shares of common stock (the “Warrants”) as described below. On December 9, 2014, December 31, 2014, and February 2, 2015, the Company sold an additional $46,000, $85,000 and $210,000, respectively, of principal amount of the Notes and Warrants to various accredited investors. This private placement, which generated aggregate gross proceeds of $579,500, was terminated effective February 18, 2015. Unless otherwise provided for in the Notes, the outstanding principal balance of each Note and all accrued and unpaid interest, compounded annually at 10%, when issued, was due and payable in full on September 15, 2015. 

At any time, each Purchaser may elect, at its option and in its sole discretion, to convert the outstanding principal amount into a fixed number of shares of the Company’s common stock equal to the quotient obtained by dividing the outstanding principal amount by $0.035, plus any accrued and unpaid interest, which is treated in the same manner as the outstanding principal amount. In the case of a Qualified Financing (as defined in the Purchase Agreement), the outstanding principal amount and accrued and unpaid interest under the Notes automatically convert into common stock at a common stock equivalent price of $0.035. In the case of an Acquisition (as defined in the Purchase Agreement), the Company may elect to either: (i) convert the outstanding principal amount and all accrued and unpaid interest under the Notes into shares of common stock or (ii) accelerate the maturity date of the Notes to the date of closing of the Acquisition. Each Warrant to purchase shares of common stock is exercisable into a fixed number of shares of common stock of the Company calculated as each Purchaser’s investment amount divided by $0.035. The Warrants, when issued, were exercisable through September 15, 2015 at a fixed price of $0.035 per share. The Warrants do not have any cashless exercise provisions. The shares of common stock issuable upon conversion of the Notes and exercise of the Warrants are not subject to any registration rights.

Placement agent fees, brokerage commissions, and similar payments were made in the form of cash and warrants to qualified referral sources in connection with the sale of the Notes and Warrants. In connection with the initial closing on November 5, 2014, fees of $16,695 were paid in cash, based on 7% of the aggregate principal amount of the Notes issued to such referral sources, and the fees paid in warrants (the “Placement Agent Warrants”) consisted of 477,000 warrants, reflecting warrants for that number of shares equal to 7% of the number of shares of common stock into which the corresponding Notes are convertible. In connection with the second closing, fees of $700 were paid in cash and 20,000 Placement Agent Warrants were issued. In connection with the third closing, fees of $3,500 were paid in cash and 100,000 Placement Agent Warrants were issued. In connection with the fourth closing, fees of $14,700 were paid in cash and 420,000 Placement Agent Warrants were issued. The Placement Agent Warrants have cashless exercise provisions and were exercisable through September 15, 2015 at a fixed price of $0.035 per share. The stock warrants issued to the placement agent and/or its designees or affiliates in connection with the 2014 closings of the Purchase Agreement, to purchase 597,000 shares of the Company’s common stock, were valued pursuant to the Black-Scholes option-pricing model at $19,986, $614 and $3,340, respectively. The stock warrants issued to the placement agent and/or its designees or affiliates in connection with the February 2, 2015 closing of the Purchase Agreement, to purchase 420,000 shares of the Company’s common stock, were valued pursuant to the Black-Scholes option-pricing model at $12,726. Total financing costs relating to all closings of the Notes aggregated $129,776, consisting of $93,110 paid in cash and $36,666 paid in the form of Placement Agent Warrants, and were being amortized as additional interest expense over the original term of the Notes. During the three months and nine months ended September 30, 2015, $35,306 and $114,129, respectively, was charged to interest expense with respect to the amortization of capitalized financing costs.

Aurora Capital LLC, a related party as described at Note 8 (“Aurora”), was the placement agent for this financing, and Aurora and its designees and/or affiliates received aggregate fees in connection with this financing in the form of $33,425 in cash and Placement Agent Warrants to purchase 955,000 shares of common stock in connection with the four closings.

The Notes and Warrants were offered and sold without registration under the Securities Act in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act as provided in Rule 506 of Regulation D promulgated thereunder. The Notes and Warrants and the shares of common stock issuable upon conversion of the Notes and exercise of the Warrants have not been registered under the Securities Act or any other applicable securities laws, and unless so registered, may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act.

The Company used the Black-Scholes option-pricing model to estimate the fair value of the Warrants to purchase 16,557,142 shares of the Company’s common stock sold to investors in connection with the four closings at a fixed exercise price of $0.035 per share. The Company considered the face value of the Notes to be representative of their fair value. The Company applied the relative fair value method to allocate the proceeds from the borrowing to the Notes and the Warrants. Consequently, approximately 50% of the proceeds of the borrowing of $290,394 were attributed to the debt instrument. The 50% value attributed to the Warrants of $289,106 is being amortized as additional interest expense over the original term of the Notes. During the three months and nine months ended September 30, 2015, $84,858 and $267,812 was charged to interest expense from the amortization of debt discount related to the value attributed to the Warrants. The carrying value of the Notes was further reduced by a discount for a beneficial conversion feature of $290,394. The value attributed to the beneficial conversion feature is being amortized as additional interest expense over the original term of the Notes. During the three months and nine months ended September 30, 2015, $83,512 and $168,086, respectively, was charged to interest expense from the amortization of debt discount related to the value attributed to the beneficial conversion feature.

On August 13, 2015, the Company, pursuant to the terms of the Notes, gave the Note holders written notice, thirty days in advance of the September 15, 2015 maturity date of the Notes, of the Company’s election to extend the maturity date of the Notes to September 15, 2016. As a consequence of this election, under the terms of the Notes, the Company was required to issue to Note holders 8,903,684 additional warrants (the “New Warrants”) that are exercisable through September 15, 2016. As set forth in the Notes, the New Warrants are exercisable for that number of shares of common stock of the Company calculated as the principal amount of the Note (an aggregate amount of $579,500), plus any accrued and unpaid interest (an aggregate amount of $43,758), multiplied by 50%, and then divided by $0.035. The New Warrants otherwise have terms substantially similar to the 16,557,142 Warrants originally sold to investors. In connection with the extension of the maturity date of the Notes, the Board of Directors of the Company also determined to extend the termination date of the 16,557,142 original Warrants to September 15, 2016, so that they are coterminous with the new maturity date of the Notes.

The Company used the Black-Scholes option-pricing model to estimate the fair value of the New Warrants to purchase 8,903,684 shares of the Company’s common stock and the fair value of extending the termination date of the 16,557,142 original Warrants sold to investors. The Company considered the face value of the Notes, plus the accrued interest thereon, to be representative of their fair value. The relative fair value method generated respective fair values for each of the Notes, including accrued interest, and the New Warrants and extension of the original Warrants, of approximately 55% for the Notes, including accrued interest, and approximately 45% for the New Warrants and extension of the original Warrants. The 45% value attributed to the New Warrants and extension of the original Warrants is being amortized as additional interest expense over the extended term of the Notes. During the three months and nine months ended September 30, 2015, $11,390 was charged to interest expense from the amortization of debt discount related to the value attributed to the New Warrants and extension of the original Warrants. The carrying value of the Notes was further reduced by a discount for a beneficial conversion feature of $206,689. The value attributed to the beneficial conversion feature is being amortized as additional interest expense over the extended term of the Notes. During the three months and nine months ended September 30, 2015, $8,471 was charged to interest expense from the amortization of debt discount related to the value attributed to the beneficial conversion feature.

During the three months and nine months ended September 30, 2015, $91,983 and $274,000, respectively, was charged to interest expense from the amortization of debt discount related to the value attributed to the beneficial conversion features.

As of September 30, 2015, the 10% Convertible Notes Payable were convertible into 17,876,357 shares of the Company’s common stock, including 1,319,214 shares attributable to accrued interest of $46,172 payable as of such date. As of December 31, 2014, the 10% Convertible Notes Payable were convertible into 10,674,107 shares of the Company’s common stock, including 116,964 shares attributable to accrued interest of $4,093 payable as of such date.

Effective September 14, 2015, placement agent warrants issued in connection with the four closings of the above described Convertible Note and Warrant Purchase Agreement, representing the right to acquire a total of 1,017,000 shares of common stock, were exercised on a cashless basis, resulting in the net issuance of 47,109 shares of common stock. The gross exercise price of the placement agent warrants that were exercised on a cashless basis was $35,595.

Note Payable to Related Party

On June 25, 2012, the Company borrowed 465,000,000 Won (the currency of South Korea, equivalent to approximately $400,000 United States Dollars) from and executed a secured note payable to SY Corporation Co., Ltd., formerly known as Samyang Optics Co. Ltd. (“Samyang”), an approximately 20% common stockholder of the Company at that time. The note accrues simple interest at the rate of 12% per annum and has a maturity date of June 25, 2013, although Samyang was permitted to demand early repayment of the promissory note on or after December 25, 2012. Samyang did not demand early repayment. The Company has not made any payments on the promissory note. At June 30, 2013 and subsequently, the promissory note was outstanding and in technical default, although Samyang has not issued a notice of default or a demand for repayment. The Company believes that Samyang is in default of its obligations under its January 2012 license agreement, as amended, with the Company, but the Company has not yet issued a notice of default. The Company is continuing efforts to enter into discussions with Samyang with a view toward a comprehensive resolution of the aforementioned matters.

The promissory note is secured by collateral that represents a lien on certain patents owned by the Company, including composition of matter patents for certain of the Company’s high impact ampakine compounds and the low impact ampakine compounds CX2007 and CX2076, and other related compounds. The security interest does not extend to the Company’s patents for its ampakine compounds CX1739 and CX1942, or to the patent for the use of ampakine compounds for the treatment of respiratory depression.

In connection with this financing, the Company issued to Samyang two-year detachable warrants to purchase 4,000,000 shares of the Company’s common stock at a fixed exercise price of $0.056 per share. The warrants had a call right for consideration of $0.001 per share, in favor of the Company, to the extent that the weighted average closing price of the Company’s common stock exceeds $0.084 per share for each of ten consecutive trading days, subject to certain circumstances. Additionally, an existing license agreement with Samyang was expanded to include rights to ampakine CX1739 in South Korea for the treatment of sleep apnea and respiratory depression. The warrants expired unexercised on June 25, 2014.

The Company used the Black-Scholes option-pricing model to estimate the fair value of the two-year detachable warrants to purchase 4,000,000 shares of the Company’s common stock at a fixed exercise price of $0.056 per share. The Company applied the relative fair value method to allocate the proceeds from the borrowing to the note payable and the detachable warrants. The Company did not consider the expansion of the existing license agreement with Samyang to have any significant value. Consequently, approximately 64% of the proceeds of the borrowing were attributed to the debt instrument.

The 36% value attributed to the warrant was amortized as additional interest expense over the expected life of the note. Additionally, financing costs aggregating $21,370 incurred in connection with the transaction were also amortized over the expected life of the note. In that repayment could be demanded after six months, that period was used as the expected life of the note payable for amortization purposes.

Note payable to Samyang consists of the following at September 30, 2015 and December 31, 2014:

	September 30, 2015			December 31, 2014
Principal amount of note payable	$	399,774		$	399,774
Accrued interest payable		158,998			122,618
Foreign currency transaction adjustment		(17,561	)		3,865
	$	541,211		$	526,257

Advances from the Chairman

On June 25, 2013, the Arnold Lippa Family Trust of 2007, of which Dr. Arnold S. Lippa, the Company’s Chairman and then Chief Executive Officer is the settlor, began advancing funds to the Company for working capital purposes. At December 31, 2013, the trust had advanced a total of $75,000 to the Company. Such advances reached a maximum of $150,000 on March 3, 2014 and were due on demand with interest at a rate per annum equal to the “Blended Annual Rate”, as published by the U.S. Internal Revenue Service of approximately 0.22% for the period outstanding. In March 2014, the Company repaid the working capital advances, including accrued interest of $102, from the proceeds from the private placement of its Series G 1.5% Convertible Preferred Stock.

On June 16, 2015, Dr. Lippa advanced $40,000 to the Company for working capital purposes. Such advance was due on demand with interest at 10% per annum. On September 3, 2015, the Company repaid the working capital advance, including accrued interest of $877, from the proceeds from the August and September 2015 closings of the private placement of its units of common stock and warrants.

Other Short-Term Notes Payable

Other short-term notes payable at September 30, 2015 consisted of a promissory note issued to a service provider in connection with a debt settlement (see Note 6) and a premium financing agreement with respect to an insurance policy. The promissory note is due with 10% interest per annum at the earlier of (i) the closing of a transaction for the sale of the Company’s capital stock that results in net proceeds to the Company of at least $2,000,000, or (ii) December 31, 2015. At September 30, 2015, the balance due on the note payable was $62,685, including accrued interest of $2,922.
