6. Borrowing Arrangements

On May 10, 2013, the Company issued senior secured promissory notes (the “Senior Secured Notes” and as amended on March 26, 2014, the “Amended Secured Convertible Notes”) with an aggregate principal of $5,000,000 for proceeds of $4,950,000. In conjunction with the issuance of the Senior Secured Notes, proceeds of $50,000 were received in exchange for 5,000,000 shares of Series A-1 Preferred Stock. Also, on May 17, 2013, proceeds of $1,498,526 were received in exchange for shares of Series A-2 redeemable convertible preferred stock (“Series A-2 Preferred Stock”, and together with Series A-1 Preferred Stock, “Series A Preferred Stock”) to substantially the same investors. Total proceeds from the Senior Secured Notes, Series A-1 Preferred Stock, and Series A-2 Preferred Stock were allocated to each instrument using the relative fair value method. The fair value allocated to the Senior Secured Notes was $2,557,111. Further discussion regarding the allocation of proceeds is included in Note 7. On March 26, 2014, the Senior Secured Notes were amended and restated to allow for conversion to common stock and to amend the interest rate. In conjunction with the amendment, the Company recorded a loss on extinguishment of the Senior Secured Notes of $2,403,193 in the accompanying statements of operations.

On March 26, 2014, the Company issued certain secured convertible notes (the "New Secured Convertible Notes” and together with the Amended Secured Convertible Notes, the “Secured Convertible Notes”) with an aggregate principal of $3,000,000 with similar terms and conditions as the Amended Secured Convertible Notes.

On October 1, 2014, the Company paid the holders of the Amended Secured Convertible Notes and the New Secured Convertible Notes $8,000,000, plus interest of $187,351. In addition, the Company issued an aggregate of 1,804,030 shares of common stock to the note holders, who otherwise had the right to convert the existing notes into 1,508,162 shares of common stock of the Company until July 2018, as consideration for a waiver from such Secured Convertible Note holders in order for the Company to prepay the remaining outstanding principal and interest on the Secured Convertible Notes. As a result of the issuance of shares, the Company recorded a loss on extinguishment of $3,240,414. Immediately following the prepayment of the Secured Convertible Notes and the issuance of the shares, the Secured Convertible Notes were deemed paid in full.

Amortization of the discount on Secured Convertible Notes payable is computed using the straight line method over the note term and is included in interest expense in the accompanying statements of operations. The straight line method of amortization is not materially different than the effective interest method. Amortization of the discount was $185,474 for the twelve months ended December 31, 2014.

On December 19, 2013 and December 31, 2013, the Company issued promissory notes (the “December 2013 Notes”) to the Company’s Chief Executive Officer, a related party, for $3,000,000 and $100,000 totaling an aggregate principal of $3,100,000. The Company also incurred a loan origination fee of $60,000 upon issuance of the December 2013 Notes. The December 2013 Notes, originally scheduled to mature in February 2014, were extended to August 31, 2014 and bore interest at 2% per annum. On January 14, 2014, the Company fully repaid the $100,000 unsecured related party note as part of the December 2013 Notes. The $3,000,000 note was secured by certain patent assets of the Company and all principal and accrued but unpaid interest on the December 2013 Notes were due upon maturity.

On February 10, 2014, the Company obtained an unsecured promissory note receivable (the “Note Receivable”) from the Company’s Chief Executive Officer, a related party, with an aggregate principal of $3,000,000. The Note Receivable which matured on August 31, 2014 bore interest at 2% per annum. All principal and accrued but unpaid interest was receivable upon maturity. The Note Receivable included a full right of offset with the December 2013 Notes. The Company’s board of directors, excluding the Chief Executive Officer’s vote, approved the Note Receivable prior to issuance. Effective February 11, 2014, the December 2013 Notes and Note Receivable were fully offset and deemed paid.

On August 1, 2014, the Company obtained an unsecured promissory note payable (the “FRB Note”) from First Republic Bank with an aggregate principal of $500,000. The FRB Note, which was to mature on November 1, 2014, bore interest at 1.3% per annum. All principal and accrued, but unpaid interest, was payable upon maturity. The FRB Note was collateralized by a deposit account of the Company’s Chief Executive Officer, a related party. The FRB Note was repaid in full on October 3, 2014.

On September 23, 2014, the Company entered into a Share Purchase Agreement with Joseph W. Beyers, the Company’s Chairman and Chief Executive Officer, pursuant to which the Company agreed to issue to Mr. Beyers up to 233,640 shares of our common stock, at a purchase price of $2.14 per share for aggregate consideration to us of up to $500,000. Pursuant to the terms of such agreement and concurrently with the execution of the agreement, Mr. Beyers made an initial payment of $300,000 to the Company towards the aggregate purchase price. The shares were only to be issued if we did not obtain $6 million or more in debt financing within ten business days of the execution of the agreement. As a result of the Fortress Agreement the Company is required to return the $300,000 in cash previously prepaid by Mr. Beyers and the Company will not issue any securities as a result of the Share Purchase Agreement. As of December 31, 2014, Mr. Beyers has deferred repayment, accordingly the $300,000 has been recorded as a related party loan payable.

On October 1, 2014 the Company entered into the original Fortress Agreement with Fortress, including a Note Purchaser (as defined below) who also serves as collateral agent (the “Collateral Agent”) and a Revenue Participant (as defined below). Pursuant to the Fortress Agreement, the Company issued an aggregate of $11,000,000 in Fortress Notes to the purchasers identified in the Fortress Agreement (the “Note Purchasers”). As a result of the issuance of the Fortress Notes and the sale of the Fortress Shares (as defined below), after the payment of all purchaser-related fees and expenses relating to the issuance of the Fortress Notes and Fortress Shares, the Company received net proceeds of $9,964,868 (less issuance costs of $450,253). The Company used the net proceeds to payoff the Secured Convertible Notes and the FRB Note and for general working capital purposes. The unpaid principal amount of the Fortress Notes bears cash interest equal to LIBOR plus 7%. In addition, a 3% per annum paid-in-kind (“PIK”) interest will be paid by increasing the principal amount of the Fortress Notes by the amount of such interest. The PIK interest shall be treated as principal of the Fortress Note for all purposes of interest accrual or calculation of any premium payment.

The principal of the Fortress Notes and all unpaid interest thereon or other amounts owing hereunder shall be paid in full in cash by the Company on September 30, 2017 (the “Maturity Date”). The Company may prepay the Fortress Notes in whole or in part, generally without penalty or premium, except that any optional prepayments of the Fortress Notes prior to October 1, 2015 will be accompanied by a prepayment premium equal to 5% of the principal amount prepaid. In addition, upon the earlier of the date on which the all obligations of the Fortress Notes are paid in full, or become due the Company will pay to the Note Purchasers a termination fee equal to $770,000. This was accounted for as a discount on notes payable.

Upon receipt of any revenues generated from the monetization of the Patents (the “Monetization Revenue”) from the patents identified in the Fortress Agreement (the “Patents”), the Company is required to apply, towards its obligations pursuant to the Fortress Notes, 86% of the difference between (a) any revenues generated from the Monetization Revenue less (b) any litigation or licensing related third party expenses (including fees paid to the original patent owners) reasonably incurred by the Company to earn Monetization Revenue, subject to certain limits (such difference defined as “Monetization Net Revenues”). If Monetization Net Revenue is applied to outstanding principal of the Fortress Notes (defined as “Mandatory Prepayments”), such Mandatory Prepayments are not subject to the prepayment premium described above. To the extent that any obligations under the Fortress Notes are past due, including if such payments are past due as a result of an Acceleration of the Fortress Notes or certain conditions of breach or alleged breach have occurred, the percentage will increase from 86% to 100%.

In addition to the Mandatory Prepayments, beginning on the last business day of October 2015, the Company shall make monthly amortization payments (the “Amortization Payments”) in an amount equal to (x) the then outstanding principal amount divided by (y) the number of months left until the Maturity Date.

In connection with the execution of the Fortress Agreement, on October 1, 2014, the Company paid to the Note Purchasers a structuring fee equal to $385,000. This was accounted for as a discount on notes payable.

Pursuant to the Fortress Agreement, the Company granted to the purchasers identified in the Fortress Agreement (“Revenue Participants”) a right to receive a portion of the Company’s Monetization Revenues totaling $5,500,000 (unless the Revenue Participants have not received $5,500,000 by the Maturity Date, in which case the Revenue Participants have a right to receive a portion of Monetization Revenues totaling $8,250,000) (the “Revenue Stream”). The Revenue Participants will not receive any portion of the Revenue Stream until all obligations under the Fortress Notes are paid in full. Following payment in full of the Fortress Notes, the Company will pay to the Revenue Participants their proportionate share of the Monetization Net Revenues. The Revenue Participant’s proportionate share is equal to (a) 46% of Monetization Net Revenues until $2,750,000 has been paid to the Revenue Participants, (b) 31% of Monetization Net Revenues until the next $2,750,000 has been paid to the Revenue Participants and (c) 6% of Monetization Net Revenues until the next $2,750,000 has been paid to the Revenue Participants if (a) and (b) have not been fully paid by the Maturity Date. All Revenue Stream Payments will be payable on a monthly basis in arrears. The rights of the Revenue Participants to the Revenue Stream are secured by all of the Company’s current patent assets and the Cash Collateral Account, in each case junior in priority to the rights of the Note Purchasers. In connection with the Revenue Participants right to receive a portion of the Company’s Monetization Revenues, the Company has recorded a net liability of $2,478,057, which represents the fair value of the expected Monetization Revenues, discounted 20% over the expected life of the revenue share agreement.

The Fortress Agreement contemplates the issuance of up to an additional $5,000,000 in Fortress Notes and additional rights to receive Revenue Stream Payments (collectively, the “Additional Advances”), $3,000,000 of which was committed in March 2015 against future license receivables. If the Company makes an offer to issue Additional Advances, and if the Purchasers agree, in their sole discretion, to acquire such Additional Advances, the Fortress Agreement will be amended to reflect the economic and other terms and conditions of such Additional Advances. In particular, it is contemplated that to the extent that such Additional Advances occur, the additional Fortress Notes and participation in the Monetization Revenues will have substantially the same economic terms as those issued as of October 1, 2014.

As part of the Fortress Agreement, the Company and the Collateral Agent entered into a Patent License Agreement (the “Patent License Agreement”), under which the Company agreed to grant to the Collateral Agent a non-exclusive, royalty-free, and worldwide license to certain of its Patents (the “Licensed Patents”), which can only be used by the Collateral Agent following an occurrence and during the continuance of an event of default of the Fortress Agreement. When the Fortress Notes and Revenue Stream are paid in full, the Patent License Agreement will terminate.

As part of the transaction, the Company granted the Note Purchaser and Revenue Participant a first priority security interest in all of the Company’s currently owned patent assets and all proceeds thereof, as well as a general security interest in all of the assets of the Company and its subsidiaries. The Note Purchaser and Revenue Participant do not have a security interest in any future patent purchases by the Company.

As part of the transaction, the Company is required to maintain a minimum $1,000,000 in cash reserves. Failure to maintain that minimum cash balance can constitute an event of default under the Fortress Agreement. If we were to default under the Fortress Agreement and were unable to obtain a waiver for such a default, interest on the obligations would accrue at an increased rate. In the case of a default, Fortress could accelerate our obligations under the Fortress Agreement. See further, Risk Factors.

Unregistered Sales of Equity Securities.

In connection with the execution of the Fortress Agreement, the Company issued 500,000 shares of its common stock at $2.00 per share to the Revenue Participant for an aggregate purchase price of $1,000,000. The Fortress Shares were issued pursuant to a subscription agreement dated October 1, 2014. The shares were issued by the Company under the exemption from registration afforded by Section 4(a)(2) of the Securities Act and Regulation D promulgated thereunder, as they were issued to accredited investors, without a view to distribution, and were not issued through any general solicitation or advertisement.

On October 1, 2014, the Company paid the holders of the Amended Secured Convertible Notes and the New Secured Convertible Notes $8,000,000, plus interest of $187,351. In addition, the Company issued an aggregate of 1,804,030 shares of common stock to the note holders, who otherwise had the right to convert the existing notes into 1,508,162 shares of common stock of the Company until July 2018, as consideration for a waiver from such Secured Convertible Note holders in order for the Company to prepay the remaining outstanding principal and interest on the Secured Convertible Notes. Immediately following the prepayment of the Secured Convertible Notes and the issuance of the shares, the Secured Convertible Notes were deemed paid in full. Further, as a result of the termination of the Existing Notes, $3,500,000 previously held in a cash collateral account in connection with the Existing Notes were released to the Company.

In connection with the closing of the transactions contemplated by the Fortress Agreement, the Company paid a closing fee of $330,000. As discussed in Note 7, the Company also issued a 5 year warrant to purchase 247,500 shares common stock at an exercise price of $2.00 to National Securities Corporation, who acted as advisor to the Company with respect to the transaction. The warrant meets the requirements to be accounted for as an equity warrant. The Company estimated the fair value of the warrant to be $153,759, using the Black-Scholes option pricing model. The fair value of the warrant as of November 1, 2014 was estimated using the following assumptions:

Expected volatility	60	%
Risk free rate	1.62	%
Dividend yield	0	%
Expected term (in years)	5.00

The assumptions utilized were derived in a similar manner as discussed in Note 7 related to the fair value of stock options.
