Note 1 – Organization, Operations and Basis of Presentation

Organization and Operations

Cell Source, Inc. (“CSI” or the “Company”) is a Nevada corporation formed on June 6, 2012 that is the parent company of Cell Source Limited, which was founded in Israel in 2011 in order to commercialize a suite of inventions relating to certain cancer treatments. Cell Source Limited’s target indications include treatment of lymphoma, multiple myeloma and B-cell chronic lymphocytic leukemia (“BCLL”) (which is a common form of leukemia), facilitating transplantation acceptance (initially bone marrow transplantation and subsequently organ transplantation) and ultimately treating a variety of non-malignant diseases. Cell Source Limited’s lead prospective product is its patented Veto-Cell immune system management technology, which is an immune tolerance biotechnology that enables the selective blocking of immune responses. Cell Source Limited’s Veto-Cell immune system management technology is based on technologies patented, owned, and licensed to Cell Source Limited by Yeda Research and Development Company Limited, an Israeli corporation ("Yeda").

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, such statements include all adjustments (consisting only of normal recurring items) which are considered necessary for a fair presentation of the condensed consolidated financial position of the Company as of March 31, 2015 and the condensed consolidated results of its operations and cash flows for the three months ended March 31, 2015 and 2014 . The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the operating results for the full year. It is recommended that these condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and related disclosures of the Company as of December 31, 2014 and for the year then ended which were filed with the Securities and Exchange Commission (“SEC”) on Form 10-K on March 13, 2015.

Note 2 – Going Concern and Management Plans

The Company has not generated any revenues, has recurring net losses, a working capital deficiency as of March 31, 2015 of approximately $4,342,000, and used cash in operations of approximately $693,000 and $1,341,000 for the three months ended March 31, 2015 and 2014, respectively. In addition, as of March 31, 2015, the Company had an accumulated deficit of approximately $8,555,000. These conditions raise substantial doubt about the Company’s ability to continue as a going concern.

These unaudited condensed consolidated financial statements have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The ability of the Company to continue its operations is dependent on the execution of management’s plans, which include the raising of capital through the debt and/or equity markets, until such time that funds provided by operations are sufficient to fund working capital requirements. The Company may need to incur additional liabilities with certain related parties to sustain the Company’s existence. If the Company were not to continue as a going concern, it would likely not be able to realize its assets at values comparable to the carrying value or the fair value estimates reflected in the balances set out in the preparation of the condensed consolidated financial statements.

There can be no assurances that the Company will be successful in generating additional cash from the equity/debt markets or other sources to be used for operations. The condensed consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of assets and liabilities that might be necessary. Based on the Company’s current resources, the Company will not be able to continue to operate without additional immediate funding. Should the Company not be successful in obtaining the necessary financing to fund its operations, the Company would need to curtail certain or all operational activities and/or contemplate the sale of its assets if necessary.

Note 3 – Summary of Significant Accounting Policies

Principles of Consolidation

For June 30, 2014 and forward, the Company’s financial statements are consolidated and include the accounts of CSI and Cell Source Limited. All significant intercompany transactions have been eliminated in the consolidation. Prior to June 30, 2014, the financial statements presented are those of Cell Source Limited.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.

Management bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The most significant estimates, among other things, are used in accounting for allowances for deferred income taxes, contingencies, as well as the recording and presentation of its common stock and related warrant issuances. Estimates and assumptions are periodically reviewed and the effects of any material revisions are reflected in the financial statements in the period that they are determined to be necessary. Actual results could differ from those estimates and assumptions.

Loss Per Share

The Company computes basic net loss per share by dividing net loss by the weighted average number of common shares outstanding for the period and excludes the effects of any potentially dilutive securities. Diluted earnings per share includes the dilution that would occur upon the exercise or conversion of all dilutive securities into common stock using the “treasury stock” and/or “if converted” methods, as applicable. Weighted average shares outstanding for the three months ended March 31, 2015 and 2014 includes the weighted average impact of warrants to purchase an aggregate of 2,043,835 shares of common stock because their exercise price was determined to be nominal.

The following securities are excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive:

Derivative Financial Instruments

The fair value of an embedded conversion option that is convertible into a variable amount of shares and warrants that include price protection reset provision features are deemed to be “down-round protection” and, therefore, do not meet the scope exception for treatment as a derivative under ASC 815 “Derivatives and Hedging”, since “down-round protection” is not an input into the calculation of the fair value of the conversion option and warrants and cannot be considered “indexed to the Company’s own stock” which is a requirement for the scope exception as outlined under ASC 815.

The accounting treatment of derivative financial instruments requires that the Company record the embedded conversion option and warrants at their fair values as of the inception date of the agreement and at fair value as of each subsequent balance sheet date. Any change in fair value is recorded as non-operating, non-cash income or expense for each reporting period at each balance sheet date. The Company reassesses the classification of its derivative instruments at each balance sheet date. If the classification changes as a result of events during the period, the contract is reclassified as of the date of the event that caused the reclassification. As a result of entering into warrant agreements, for which such instruments contained a variable conversion feature with no floor, the Company has adopted a sequencing policy in accordance with ASC 815-40-35-12 whereby all future instruments may be classified as a derivative liability with the exception of instruments related to share-based compensation issued to employees or directors.

The Black-Scholes option valuation model was used to estimate the fair value of the warrants and conversion options. The model includes subjective input assumptions that can materially affect the fair value estimates. The Company determined the fair value of the Binomial Lattice Model and the Black-Scholes Valuation Model to be materially the same. The expected volatility is estimated based on the most recent historical period of time equal to the weighted average life of the warrants.

Conversion options are recorded as debt discount and are amortized as interest expense over the life of the underlying debt instrument.

Reclassifications

Certain prior period amounts have been reclassified for comparative purposes to conform to the fiscal 2015 presentation. These reclassifications have no impact on the previously reported net loss.

Recent Accounting Standards

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). ASU 2015-03 amends the existing guidance to require that debt issuance costs be presented in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as a deferred charge. ASU 2015-03 is effective on a retrospective basis for annual and interim reporting periods beginning after December 15, 2015, but early adoption is permitted. The Company does not anticipate that the adoption of this standard will have a material impact on its condensed consolidated financial statements.

The Company has implemented all new accounting standards that are in effect and may impact its condensed consolidated financial statements and does not believe that there are any other new accounting standards that have been issued that might have a material impact on its financial position or results of operations.

Note 4 - Fair Value

The Company determines the estimated fair value of amounts presented in these condensed consolidated financial statements using available market information and appropriate methodologies. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. The estimates presented in the financial statements are not necessarily indicative of the amounts that could be realized in a current exchange between buyer and seller. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. These fair value estimates were based upon pertinent information available as of March 31, 2015 and December 31, 2014, and, as of those dates, the carrying value of all amounts approximates fair value. The Company performed valuations to estimate the fair value of its common stock during the three months ended March 31, 2015. To determine the value of its common stock, the Company considered the following three possible valuation methods (1) the income approach, (2) the market approach and the (3) cost approach to estimate its enterprise value.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 4 - Fair Value – Continued

The Company has categorized its assets and liabilities at fair value based upon the following fair value hierarchy:

Level 1 - Inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Level 2 - Inputs use directly or indirectly observable inputs. These inputs include quoted prices for similar assets and liabilities in active markets as well as other inputs such as interest rates and yield curves that are observable at commonly quoted intervals.

Level 3 - Inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset or liability.

In instances where inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair measurements requires judgment and considers factors specific to each asset or liability.

Both observable and unobservable inputs may be used to determine the fair value of positions that are classified within the Level 3 category. As a result, the unrealized gains and losses for assets within the Level 3 category presented in the tables below may include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in historical company data) inputs.

The following table summarizes the valuation of the Company’s derivatives by the above fair value hierarchy levels as of March 31, 2015 and December 31, 2014 using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3):

Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. The Company’s Level 3 liabilities shown in the above table consist of warrants with “down-round protection”, as the Company is unable to determine if it will have sufficient authorized common stock to settle such arrangements, and an accrued obligation to issue warrants to certain founders of Cell Source Limited, which such warrants were not issued as of March 31, 2015.

Note 4 - Fair Value – Continued

Assumptions utilized in the valuation of Level 3 liabilities are described as follows:

The expected term used is the contractual life of the instrument being valued. Since the Company’s stock has not been publicly traded for a sufficiently long period of time, the Company is utilizing an expected volatility based on a review of the historical volatilities, over a period of time, equivalent to the expected life of the instrument being valued, of similarly positioned public companies within its industry. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued.

The following table provides a summary of the changes in fair value, including net transfers in and/or out, of all Level 3 liabilities measured at fair value on a recurring basis using unobservable inputs during the three months ended March 31, 2015:

The Company’s significant financial instruments such as cash, other current assets, accounts payable, accrued expenses and notes payable were deemed to approximate fair value due to their short term nature.

On November 10, 2014, five-year warrants to purchase an aggregate of 3,000,000 shares of common stock at an exercise price of $0.75 per share were earned by certain founders of Cell Source Limited (half of which are employees thereof) but had not been issued as of March 31, 2015. As a result, the Company accrued for the value of the warrant obligation, which, using the Black Scholes option pricing model, was determined to be an aggregate of $891,400 and $901,300, respectively, which was a component of accrued compensation in the condensed consolidated balance sheets as of March 31, 2015 and December 31, 2014, respectively. During the three months ended March 31, 2015, the Company recorded a credit of $9,900 to stock-based compensation expense related to the change in value of the warrant obligation. As of March 31, 2015, the Board has neither approved a stock option plan nor has it issued the warrants, such that the warrants are not included in the summary of warrant activity in Note 9 – Stockholders’ Deficiency – Stock Warrants.

On October 28, 2013, as a result of entering into warrant agreements, for which such instruments contained a variable conversion feature with no floor, the Company has adopted a sequencing policy in accordance with ASC 815-40-35-12 whereby these and all future instruments may be classified as a derivative liability with the exception of instruments related to share-based compensation issued to employees or directors. As of March 31, 2015 and December 31, 2014, derivative liabilities valued at $2,462,400 and $2,318,700, respectively, were comprised of warrants to purchase an aggregate of 6,959,324 and 6,459,324 shares of common stock, respectively, and were deemed to be derivative liabilities.

Note 5 – Accounts Payable and Accrued Expenses

Accounts payable and accrued expenses consisted of the following:

Note 6 – Notes Payable

On March 26, 2015, the Company issued one-year notes payable in the aggregate principal amount of $500,000. The notes are non-interest bearing. The notes must be prepaid in whole from the proceeds of any closing after the issuance date, of any offering or offerings pursuant to which the Company receives aggregate gross proceeds greater than or equal to $3,000,000.

In consideration of the loans, four-year warrants to purchase an aggregate of 500,000 shares of common stock at an exercise price of $0.75 per share, with an aggregate issuance date value of $177,200, were issued by the Company to the purchasers of the notes payable and were recorded as a debt discount under the residual value method. In connection with the Company’s sequencing policy, the warrants were determined to be derivative liabilities. See Note 4 – Fair Value for additional details. During the three months ended March 31, 2015, the Company recorded amortization of debt discount of $2,400. The effective annual interest rate of the notes is 35%.

Prior to the expiration date, the Company shall have the option to redeem all of the warrants then outstanding upon not less than thirty (30) days’ nor more than (60) days’ notice to the applicable purchaser, at a redemption price of $0.01 per share, subject to the conditions that: (i) there is an effective registration statement covering the resale of the underlying shares of common stock and (ii) the common stock has traded for twenty (20) consecutive days with a closing price of at least $2.50 per share with an average trading volume of 100,000 shares per day.

Note 7 – Advances Payable

During the three months ended March 31, 2015, the Company received an aggregate of $450,000 from investors in connection with a future offering of convertible notes that had not closed as of March 31, 2015. These advances were included in other current liabilities on the condensed consolidated balance sheet as of March 31, 2015. Upon closing of the offering, the Company will evaluate and record the impact of the conversion feature.

Note 8 – Related Parties

For the three months ended March 31, 2015 and 2014, the Company recorded a charge to operations of approximately $200,000 and $212,000, respectively, related to its research and license agreement with Yeda. As of March 31, 2015 and December 31, 2014, approximately $178,000 and $285,000 has been accrued and is payable to Yeda, respectively.

Overview

Our wholly-owned subsidiary, Cell Source Israel was founded in 2011 as a privately held company located in Tel Aviv, Israel. Our business is based on over ten (10) years of prominent research at the Weizmann Institute, the commercial arm of Yeda, from whom we license patented technology. Our exclusive, world-wide license provides us with access to certain discoveries, inventions and other intellectual property generated by Dr. Reisner, formerly Head of the Immunology Department at the Weizmann Institute, together with others. Dr. Reisner leads a team at the Weizmann Institute to continue the development of these technologies in order to facilitate the transition of those technologies from the laboratory to clinical trials. We also collaborate with Dr. Herman Einsele and Dr. Franco Aversa, leading figures in bone marrow transplantation for cancer treatment and research, both of whom plan to serve on our Scientific Advisory Board and will oversee our initial clinical trials which, when started, will focus on addressing cancer through cell therapy accompanied by bone marrow transplants.

Our lead prospective product is our patented Veto-Cell immune system management technology, which is an immune tolerance biotechnology that enables the selective blocking of immune responses. The Company’s target indications include: lymphoma, multiple myeloma and BCLL (a form of leukemia treatment), facilitating transplantation acceptance (initially bone -marrow transplantation and subsequently organ transplantation), and ultimately treating a variety of non-malignant diseases.

Prior to commercializing its products, the Company must conduct human clinical trials and obtain FDA approval and/or approvals from comparable foreign regulatory authorities.

Generally speaking, as a preclinical biotechnology firm, Cell Source needs to go through several necessary steps in order to commercialize its products and commence revenue generation. These steps are per product, but can run in parallel for multiple products, which are each in different stages of the development “pipeline”, so that, for example, when a certain product is already in a human clinical trial, another product may still be in preclinical development and a third may be awaiting regulatory approval to commence human trials. These can also take place in parallel, and varied stages, for the same product in different geographic jurisdictions. The typical steps per product (and range of time frame for each) are:

Please note that steps 12-15 can be conducted in parallel with some of the steps above. In the case of Cell Source and other firms that treat terminal patients with either rare diseases or those for which there is currently no effective treatment, or where preclinical studies indicate a reasonable expectation to increase life expectancy and survival rates by a substantive margin, several of these steps can be combined and or shortened, subject to regulatory discretion. For example, Phase I and II (safety and efficacy) can be combined in a single concurrent step; approvals for subsequent steps can be accelerated; in some countries patients can already be treated commercially after the end of Phase II, foregoing the requirement for Phase III data.

Although we have provided estimated timeframes for each step above, no assurances can be made that such timeframes are accurate or that they would not be delayed for one or more reasons. At any stage of human clinical trial, there could be problems with either safety or efficacy of treatment. In these instances the Company could be required to reformulate the treatment and proceed with additional patients, which could involve a delay of months or years, depending on whether we would have to seek approval from the very beginning of the approval process. There can also be a delay of up to 1 to 2 years between phases of human clinical trial, as the regulator may wish to take additional time to review the approval of a subsequent stage. Furthermore, if a significant modification to the treatment is required, the application process begins again from the very first stage. If the treatment is not effective at all or if it’s harmful to patients, even after modifications are made, it is possible that the trials may be halted completely and the product candidates permanently withdrawn. While the timescales presented here are representative of the typical experience, there is no assurance that there will not be significant delays at any stage or step in the process or a complete failure of trials.

The specific detailed next steps the company must take to get the treatments or products to market include the following:

We have not submitted any drug applications to the FDA and do not have anything pending for approval with the FDA. Cell Source itself has not had any contact with any regulator anywhere regarding treatment approvals or clinical trials associated with regulatory approvals. We are aware that a hospital in Italy in May, 2014 independently requested and in September, 2014 received approval to conduct a trial with the same protocol that we plan to use, but we are not mentioned in the application nor in the approval. However, we may indirectly benefit from the outcome of the trial, if successful, although we are not the sponsor of this trial. There are no written or verbal agreements between the hospital and Cell Source regarding the use of the technology. That said, Cell Source is aware and in favor of the hospital plans to use the technology and would of course find a positive initial outcome encouraging. Since the treatment is being done on compassionate grounds as a non-commercial clinical trial, there is no legal requirement for the hospital to obtain approval to use the treatment protocol.

Cell Source then plans to commence a follow-on full Phase I/II study in Parma, Italy that is meant to demonstrate safety and efficacy and is anticipated to last between 2 and 3 years. The local regulator will then determine whether the product will then be made available for sale, or whether it will require a Phase III study. Since the product involves treatments that are already in the clinic but in combination in a new way, and since Cell Source aspires to demonstrate a significant increase in survival rates, this treatment may conceivably be made available commercially on a “compassionate grounds” basis immediately following the conclusion of Phase I/II, which could be in 2019. In the event that a full Phase III study is required, a further 2-3 years may be required.

For the Veto-Cell applications for reducing rejection in Bone Marrow Transplants and for eradicating lymphoma cells, Cell Source expects to commence a Phase I/II human clinical study in Italy, and subsequently in Germany, starting sometime in 2016. Since this technology does not involve elements that are already in clinical use, Cell Source anticipates that Phase I/II studies will last until 2018 or 2019. These would be followed by completion of Phase II and Phase III, which would last another 2-3 years each, so that full approval, if successful, would be expected sometime in 2024. In Germany there is a possibility of approval for commercial use on a “compassionate grounds” basis at the end of Phase II, which could take place by 2022. In the US, Cell Source may or may not be permitted by the FDA to submit European trial results as “supporting data”. If not, Cell Source would have to go through the full FDA approval process, which, commencing in 2015, would last until between 2021 and 2023 for the Megadose Drug Combination. For the Veto-Cell this would commence in 2016 or 2017 and could last until 2024 to 2025. It is possible that Cell Source treatments could qualify for any or all of Fast Track, Breakthrough Therapy, Accelerated Approval and Priority Review designation under the FDA, which would hasten their approval if successful.

The costs for each step of development, in terms of clinical trials, are delineated below:

Cell Source estimates the cost of clinical trials alone to be up to $5 million over the coming two years and another $25-50 million in order to reach commercialization for both the Megadose Drug Combination and the Veto-Cell products. This would mean that Cell Source will need to secure one or more significant capital infusions in order to reach the point that meaningful revenues could be generated.

Cell Source will require additional financing for any and all of the steps described above.

Recent Developments

During the three months ended March 31, 2015, we received an aggregate of $450,000 from investors in connection with a future offering of convertible notes that had not closed as of March 31, 2015.

On March 26, 2015, we issued one-year notes payable in the aggregate principal amount of $500,000. The notes are non-interest bearing. The notes must be prepaid in whole from the proceeds of any closing after the issuance date, of any offering or offerings pursuant to which we receive aggregate gross proceeds greater than or equal to $3,000,000. In consideration of the loans, four-year warrants to purchase an aggregate of 500,000 shares of common stock at an exercise price of $0.75 per share, with an aggregate issuance date value of $177,200, were issued by us to the purchasers of the notes payable.

Consolidated Results of Operations

Three Months Ended March 31, 2015 Compared to Three Months Ended March 31, 2014

The following table presents selected items in our unaudited condensed consolidated statements of operations for the three months ended March 31, 2015 and 2014, respectively:

Research and Development

Research and development expense was $252,747 and $536,775 for the three months ended March 31, 2015 and 2014, respectively, a decrease of $284,028, or 53%, primarily attributable to higher legal fees associated with patent activity during the 2014 period.

Selling, General and Administrative

Selling, general and administrative expense was $334,996 and $235,967 for the three months ended March 31, 2015 and 2014, respectively, an increase of $99,029, or 42%, primarily as a result of increased professional fees associated with being a public company.

Change in Fair Value of Derivative Liability

The change in fair value of derivative liability for the three months ended March 31, 2015 and 2014, was a gain of $33,500 and a loss of $47,500, respectively, which represents the change in fair value of the warrants that were deemed to be derivative liabilities during the respective periods.

Amortization of Debt Discount

Amortization of debt discount was $2,400 and $0 for the three months ended March 31, 2015 and 2014, respectively, which is associated with the warrants issued on March 26, 2015 in connection with notes payable.

Liquidity and Going Concern

We measure our liquidity in a number of ways, including the following:

We have not generated any revenues since our inception, we have recurring net losses, we have a working capital deficiency as of March 31, 2015 of approximately $4,342,000 and we have used cash in operations of approximately $693,000 and $1,341,000 during the three months ended March 31, 2015 and 2014, respectively. These conditions raise substantial doubt about our ability to continue as a going concern. Based on our current resources, we will not be able to continue to operate without additional immediate funding.

Our ability to continue our operations is dependent on the execution of management’s plans, which include the raising of capital through the debt and/or equity markets, until such time that funds provided by operations are sufficient to fund working capital requirements. We may need to incur additional liabilities with certain related parties to sustain our existence. If we were not to continue as a going concern, we would likely not be able to realize our assets at values comparable to the carrying value or the fair value estimates reflected in the balances set out in the preparation of our financial statements.

There can be no assurances that we will be successful in generating additional cash from equity or debt financings or other sources to be used for operations. Should we not be successful in obtaining the necessary financing to fund our operations, we would need to curtail certain or all operational activities and/or contemplate the sale of our assets, if necessary.

During the three months ended March 31, 2015 and 2014, our sources and uses of cash were as follows:

Net Cash Used in Operating Activities

We experienced negative cash flows from operating activities for the three months ended March 31, 2015 and 2014 in the amounts of $693,000 and $1,340,538, respectively. The net cash used in operating activities for the three months ended March 31, 2015 was primarily due to cash used to fund a net loss of $556,643, adjusted for net non-cash credits in the aggregate amount of $40,785, and $95,572 of net cash used to fund changes in the levels of operating assets and liabilities, primarily as a result of payments to vendors due to improved cash availability. The net cash used in operating activities for the three months ended March 31, 2014 was primarily due to cash used to fund a net loss of $820,242, adjusted for non-cash expenses in the aggregate amount of $47,500, and $567,796 of net cash used to fund changes in the levels of operating assets and liabilities, primarily as a result of payments to vendors due to improved cash availability.

Net Cash Provided by Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2015 and 2014 was $950,000 and $2,247,746, respectively. The net cash provided by financing activities during the three months ended March 31, 2015 was attributable to $500,000 of proceeds from the issuance of notes payable and $450,000 of proceeds received in connection with a convertible note offering prior to closing. The net cash provided by financing activities during the three months ended March 31, 2014 was attributable to $2,247,746 of net proceeds from the issuance of common stock and warrants.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

There are no material changes from the critical accounting policies set forth in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K which was filed with the SEC on March 13, 2015. Please refer to that document for disclosures regarding the critical accounting policies related to our business.

Recent Accounting Standards

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). ASU 2015-03 amends the existing guidance to require that debt issuance costs be presented in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as a deferred charge. ASU 2015-03 is effective on a retrospective basis for annual and interim reporting periods beginning after December 15, 2015, but early adoption is permitted. We do not anticipate that the adoption of this standard will have a material impact on our condensed consolidated financial statements.

We have implemented all new accounting standards that are in effect and may impact our financial statements and do not believe that there are any other new accounting standards that have been issued that might have a material impact on our financial position or results of operations.

Not applicable.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Disclosure controls are procedures that are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), such as this Quarterly Report, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including the Principal Executive and Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Internal controls are procedures which are designed with the objective of providing reasonable assurance that (1) our transactions are properly authorized, recorded and reported; and (2) our assets are safeguarded against unauthorized or improper use, to permit the preparation of our condensed consolidated financial statements in conformity with United States generally accepted accounting principles.

In connection with the preparation of this Quarterly Report on Form 10-Q for the quarter ended March 31, 2015, management, with the participation of our Principal Executive and Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) and 15d-15(e)). Based upon that evaluation, our Principal Executive and Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective.

Changes in Internal Controls

There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or 15d-15 under the Exchange Act that occurred during the quarter ended March 31, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations of the Effectiveness of Control

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations of any control system, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.
