– Summary of Significant Accounting Policies

Nature of Business

The Coretec Group Inc. (the “Group”) (formerly

3DIcon

Corporation) (

“3DIcon”

) was incorporated on

August 11, 1995,

under the laws of the State of Oklahoma as First Keating Corporation. The articles of incorporation were amended

August 1, 2003

to change the name to

3DIcon

Corporation. During

2001,

First Keating Corporation began to focus on the development of

360

-degree holographic technology. From

January 1, 2001,

3DIcon’s

primary activity has been the raising of capital in order to pursue its goal of becoming a significant participant in the development, commercialization and marketing of next generation

display technologies.

Coretec Industries, LLC (“Coretec”), a wholly owned subsidiary of

the Group (collectively the “Company”), was organized on

June 2, 2015

in the state of North Dakota. Coretec is currently developing, testing, and providing new and/or improved technologies, products, and service solutions for energy-related industries including, but

not

limited to oil/gas, renewable energy, and distributed energy industries. Many of these technologies and products also have application for medical, electronic, photonic, display, and lighting markets among others. Early adoption of these technologies and products is anticipated in markets for energy storage (Li-ion batteries), renewable energy (BIPV), and electronics (Asset Monitoring).

Reverse Acquisition

May 31, 2016,

the Group entered into a Share Exchange Agreement (the “Share Exchange Agreement”) with Coretec and

four

Coretec members (the “Members”), which Members held all outstanding membership interests in Coretec. On

September 30, 2016 (

the “Closing Date”), the Group closed the transaction contemplated by the Share Exchange Agreement. Pursuant to the Share Exchange Agreement, the Members agreed to sell all their membership interests in Coretec to the Group in exchange for the Group’s issuance of an aggregate

4,760,872

shares of the Group’s Series B Convertible Preferred Stock to the Members (the “Exchange”). Coretec became a wholly-owned subsidiary of the Group and the former Members beneficially owned approximately

65%

of the Group’s common stock on a fully-diluted basis on the Closing Date. Upon the closing of the Share Exchange Agreement,

two

of the Group’s Directors resigned and

three

new Directors associated with Coretec were nominated and elected, giving control of the board of directors to former Coretec Members. The

65%

holders of the Group common stock were unable to sell that stock for a period of

one

year under the terms of a lock-up agreement reached between the parties. Victor Keen, the largest shareholder of the Group prior to the reverse acquisition, was also a participant in the lock-up agreement.

Authorization of Name Change

February 21, 2017,

the Board unanimously approved the proposal to seek stockholder approval and authorization to amend the

3DIcon

Certificate of Incorporation to change the name of

3DIcon

to “The Coretec Group Inc.” (the “Name Change”) and thereafter change its trading symbol to a trading symbol resembling the name of the Group following the Name Change. On

February 21, 2017,

a majority of the Group’s stockholders adopted resolutions by written consent authorizing the Board to undertake the Name Change. This Name Change became effective

June 28, 2017

upon the Group’s filing of the Name Change Amendment with the Secretary of State of the State of Oklahoma.

Authorization of Reverse Stock Split

February 21, 2017 (

the “Record Date”), the Board of Directors unanimously approved, and a majority of the

Company’s stockholders, as of the Record Date, approved by written consent pursuant to Section

1073

of the Oklahoma Act, to permit the Company’s Board of Directors, in its sole discretion, to effectuate

one

or more consolidations of the issued and outstanding shares of common stock at some future date

later than the

first

anniversary of the Record Date, pursuant to which the shares of common stock would be combined and reclassified into

one

validly issued fully paid and non-assessable share of common stock at a ratio (the “Reverse Split Ratio”) within the range of

-for-

and up to

-for-

300

(the “Reverse Split Range”), with each stockholder otherwise entitled to receive a fractional share of common stock as a result of the Reverse Stock Split. Effective

June 28, 2017,

a Reverse Stock Split pursuant to the maximum stated Reverse Split Ratio, each

300

shares of our issued and outstanding common stock was automatically converted into

share of common stock.

Basis of Presentation

Under accounting principles generally accepted in the United States of America (“U.S. GAAP”), the acquisition is treated as a “reverse acquisition” under the purchase method of accounting (see Note

). The consolidated statements of operations herein reflect the historical results of Coretec prior to the completion of the reverse acquisition since it was determined to be the accounting acquirer, and do

not

include the historical results of operations for

3DIcon

prior to the completion of the acquisition.

3DIcon

’s assets and liabilities were consolidated with the assets and liabilities of Coretec as of the

September 30, 2016

consummation of the acquisition and are included in the consolidated balance sheet as of

December 31, 2016.

The number of shares issued and outstanding and additional paid-in capital of the Company have been retroactively adjusted to reflect the equivalent number of shares issued by the Group in the Share Exchange Agreement, while Coretec’s historical members’ deficit is being carried forward as the Group’s accumulated deficit. All costs attributable to the reverse merger were expensed.

Principles of Consolidation

The consolidated balance sheet

s as of

December 31, 2017

and

2016

include the accounts of the Group and its wholly owned subsidiary, Coretec. The consolidated statements of operations and cash flows for the year ended

December 31, 2017

include the accounts of the Group and Coretec for the entire year. The consolidated statements of operations and cash flows for the year ended

December 31, 2016

include the accounts of Coretec for the entire year and the accounts of the Group from

September 30, 2016,

the acquisition date, to

December 31, 2016.

Intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results could differ from the estimates and assumptions used.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is recorded over the estimated useful lives using the straight-line method. Maintenance and repairs are expensed as incurred; major improvements and betterments are capitalized.

Estimated useful lives of property and equipment are as follows for the major classes of assets:

Asset Description		Estimated Lives (years)
Furniture and fixtures			7

Intangible Assets

Intangible assets consist primarily of acquired patents. The

Company acquired

$1,400,000

of intangible assets in conjunction with the reverse acquisition discussed in Note

and Note

Intangible assets with finite lives are amortized on a straight-line basis over their useful lives.

Goodwill

Goodwill was acquired with the reverse

acquisition discussed in Note

and Note

The Company evaluates the carrying value of goodwill on an annual basis and between annual evaluations if events occur or circumstances change that would more likely than

not

reduce the fair value of goodwill below its carrying amount. When assessing whether goodwill is impaired, management considers

first

a qualitative approach to evaluate whether it is more likely than

not

the fair value of the goodwill is below its carrying amount; if so, management considers a quantitative approach by analyzing changes in performance and market based metrics as compared to those used at the time of the initial acquisition. For the periods presented,

impairment charges were recognized.

Long-Lived Assets

Long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset

may

not

be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the

Company

first

compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is

not

recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and

third

party independent appraisals, as considered necessary.

Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of each class of financial instrument held by the

Company:

Current assets and current liabilities

- The carrying value approximates fair value due to the short maturity of these items.

Notes payable

- The fair value of the Company's notes payable has been estimated by the Company based upon the liability's characteristics, including interest rate. The carrying value approximates fair value.

Basic and Diluted Loss Per Common Share

Basic loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other instruments to issue common stock were exercised or converted into common stock.

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

	December 31,
	201 7		201 6
Options		2,950,262		76,577
Warrants		32,728		65,228
Series A convertible preferred stock		115,000		115,000
Series B convertible preferred stock		-		41,842,241
Convertible debentures		84,103,256		26,716,467
Total potentially dilutive shares		87,201,246		68,815,513

Note - Share information for the periods has been retroactively adjusted to reflect the

June 28, 2017

one

for

300

reverse split of the Company's common stock.

Research and Development

Research and development costs are expensed as incurred. Research and development costs amounted to approximately $

456,000

and

$301,000

for the years ended

December 31, 2017

and

2016,

respectively.

Income Taxes

The

Company accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments of changes in tax laws or rates. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized.

Prior to the reverse acquisition, Coretec elected to be taxed as a Partnership for federal and state income tax purposes. Under this election substantially all of the profits, losses, credits and deductions of Coretec were passed through to the individual members. Therefore, prior to the reverse acquisition,

provision or liability for income taxes has been included in these consolidated financial statements.

Prior to the reverse acquisition,

3DIcon

’s tax benefits were fully offset by a valuation allowance due to the uncertainty that the deferred tax assets would be realized. Management considers the likelihood of changes by taxing authorities in its filed income tax returns and recognizes a liability for or discloses potential changes that management believes are more likely than

not

to occur upon examination by tax authorities. Management has

not

identified any uncertain tax positions in filed income tax returns that require recognition or disclosure in the accompanying consolidated financial statements.

2016

will make

eight

targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU

2016

is effective for public companies for interim and annual periods beginning after

December 15, 2017,

with early adoption permitted. The new standard will require adoption on a retrospective basis unless it is impracticable to apply, in which case it would be required to apply the amendments prospectively as of the earliest date practicable. ASU

2016

not

expected to have a material impact on the Company’s cash flows.

February 2016,

the FASB issued accounting standards update (ASU)

No.

2016

02,

Leases (Topic

842

)

intended to increase transparency and comparability among companies by requiring most leases to be included on the balance sheet and by expanding disclosure requirements. This is effective for public business entities for fiscal years beginning after

December 15, 2018,

including interim periods within those fiscal years. Early application is permitted for all public business entities and all nonpublic business entities upon issuance. The Company is currently evaluating the impact that this new guidance

may

have on its consolidated results of operations, cash flows, financial position and disclosures.

The FASB has issued ASU

2014

09,

Revenue from Contracts with Customers

. This ASU supersedes the revenue recognition requirements in FASB ASC

605

- Revenue Recognition and most industry-specific guidance throughout the Codification. The standard requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. On

July 9, 2015,

the FASB deferred the effective date of ASU

No.

2014

from annual periods beginning after

December 15, 2016

to annual periods beginning after

December 15, 2017.

This ASU should be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. The adoption of this standard is

not

expected to have a material impact on the Company’s consolidated financial position and results of operations.

January 2017,

the FASB issued ASU

2017

01,

Business Combinations (Topic

805

): Clarifying the Definition of a Business

. This ASU provides a screen to determine when a set is

not

a business. The screen requires that when substantially all of the fair value of gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is

not

a business. The amendments in this ASU are effective beginning after

December 15, 2017,

including interim periods within those periods and should be applied prospectively. The Company does

not

anticipate that the adoption of this standard will have a material impact on its consolidated financial position and results of operations.

January 2017,

the FASB issued ASU

2017

04,

Intangibles – Goodwill and Other (Topic

350

): Simplifying the Test for Goodwill Impairment

. This ASU simplifies the subsequent measurement of goodwill by eliminating Step

from the goodwill test. Under Step

an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and labilities following the procedure that would be required in determining the fair value of assets acquires and labilities assumed in a business combination. Instead, an entity should perform its annual, or intern, goodwill impairment test by comparing the fair value of a reporting unity with its carrying amount. The amendments in this ASU are effective beginning after

December 15, 2019,

however early adoption is permitted beginning

January 1, 2017

and should be applied on a prospective basis. The Company does

not

anticipate that the adoption of this standard will have a material impact on its consolidated financial position and results of operations.

Uncertainties

The

Company has realized a cumulative net loss of

$2,593,337

for the period from inception (

June 2, 2015)

December 31, 2017,

negative working capital of

1,904,514,

and

revenues. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a year following the issuance of these consolidated financial statements. The Company has insufficient revenue and capital commitments to fund the development of its planned products and to pay operating expenses.

The ability of the

Company to continue as a going concern depends on the successful completion of the Company's capital raising efforts to fund the development of its planned products. The Company intends to continue to raise additional capital through debt and equity financings. There is

assurance that these funds will be sufficient to enable the Company to fully complete its development activities or attain profitable operations. If the Company is unable to obtain such additional financing on a timely basis or, notwithstanding any request the Company

may

make, the Company’s debt holders do

not

agree to convert their notes into equity or extend the maturity dates of their notes, the Company

may

have to curtail its development, marketing and promotional activities, which would have a material adverse effect on the Company’s business, financial condition and results of operations, and ultimately the Company could be forced to discontinue its operations and liquidate.

The accompanying consolidated financial statements have been prepared in conformity with U.S. GAAP, which contemplates the continuation of the

Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the consolidated financial statements do

not

necessarily purport to represent realizable or settlement values. The consolidated financial statements do

not

include any adjustments that might result from the outcome of this uncertainty.

Under the terms of the Golden State Equity Investors, Inc (“Golden State”)

4.75%

Convertible Debenture due on

December 31,

2017,

subsequently extended to

June 30, 2018,

Golden State is obligated to submit conversion notices in an amount such that Golden State receives

of the outstanding shares of the Company every calendar quarter for a period of

one

year. In connection with each conversion, Golden State is expected to simultaneously exercise a percentage of warrants equal to the percentage of the principal being converted. The warrants are exercisable at

$114,450

per share. The number of warrants exercisable is subject to certain beneficial ownership limitations contained in the

4.75%

Convertible Debenture (“the Beneficial Ownership Limitations”). The Beneficial Ownership Limitations prevent Golden State from converting on the

4.75%

Convertible Debenture or exercising warrants if such conversion or exercise would cause Golden State’s holdings to exceed

9.99%

of the Company’s issued and outstanding common stock. Subject to the Beneficial Ownership Limitations and provided that Golden State is able to sell the shares under Rule

144,

Golden State is required to convert

$28.60

of the

4.75%

Convertible Debenture and exercise

2.86

warrants per month. Based upon the current stock price, the issued and outstanding shares as of

December 31, 2017

and ignoring the impact of the Beneficial Ownership Limitations, the Company

may

receive up to

$327,000

per month in funding for the duration of the debenture from Golden State as a result of warrant exercises. Due to the number of authorized common shares available in the year ended

December 31, 2016

and the Beneficial Ownership Limitations, Golden State provided only

$29,700

in funding in the year ended

December 31, 2016

and -

May 31, 2016,

the Group entered into a Share Exchange Agreement with Coretec and its Members, which Members held all outstanding membership interests in Coretec. Pursuant to the Share Exchange Agreement, the Members agreed to sell all their membership interests in Coretec to the Group in exchange for the Group’s issuance of an aggregate

4,760,872

shares of the Group’s Series B Convertible Preferred Stock to the Members.

Upon the

September 30, 2016

closing of the Share Exchange Agreement, considering any preferred stock on an “as converted” basis, approximately

65%

of the Group’s issued and outstanding common stock was owned by the former Coretec Members. The remaining

35%

was held by the Group’s prior stockholders. Upon the closing of the Share Exchange Agreement,

two

of the former Group’s directors resigned and

three

new directors associated with Coretec were nominated and elected, giving control of the board of directors to the former Coretec Members. The

65%

holders of the Group’s common stock on an as converted basis were unable to sell that stock for a period of

one

Consummation of the Exchange was subject to customary conditions, including without limitation, (i) Coretec

’s delivery to the Group a representation letter attesting to each of the Members’ or their designees’ status as an “accredited investor;” (ii) Coretec’s delivery to the Group a letter agreement executed by each of the Members or their designees, if any, agreeing to automatically convert the shares of Series B Preferred issued to them pursuant to the Share Exchange Agreement upon the occurrence of certain events; (iii) Coretec’s delivery to the Group a lock up agreement executed by each of the Members or their designees, if any, in the form attached to the Share Exchange Agreement; (iv) Coretec’s delivery to the Group a license agreement between Coretec and North Dakota State University allowing Coretec to license certain intellectual property concerning cyclohexasilane or other silicon-based materials; (v) the delivery to the Group of the required Coretec audited and unaudited financial statements; and (vi) delivery by the Group and Coretec all required consents to consummate all transactions contemplated by the Share Exchange Agreement.

The

Company engaged a law firm to prepare the necessary documents for the Share Exchange Agreement, including resolutions of the entities authorizing the closing, preparation and filing of Form

14F,

and filing of the Form

8K.

As of

December 31, 2016,

the law firm had completed the engagement and the Company has expensed

$100,000,

$75,000

of which was recognized in the financial statements of

3DIcon

prior to the

September 30, 2016

Share Exchange Agreement.

The

Company has a complex equity structure which includes

two

series of preferred stock, common stock, warrants and options. The acquisition date fair value of the consideration transferred was calculated as follows:

Company enterprise value	$	1,378,026

Less: interest bearing debt		(493,958	)

Company equity value	$	884,068

The fair value of the assets acquired and liabilities assumed at the closing date were based on management estimates, except for the patents which were valued by an independent valuation expert. Based upon the preliminary purchase price allocation, the following table summarizes the estimated provisional fair value of the assets acquired and liabilities assumed at the date of acquisition:

Cash	$	75,687
Prepaid expenses		46,513
Due from related party		52,019
Patents		1,400,000
Deposits		2,315
Total assets acquired at fair value		1,576,534

Accounts payable and accrued expenses		364,508
Notes payable		89,465
Notes payable - related party		404,493
Total liabilities assumed		858,466
Total identifiable net assets		718,068
Goodwill		166,000
Total preliminary purchase consideration	$	884,068

The purchase price exceeded the fair value of the net assets acquired by approximately

$166,000,

which was recorded as goodwill.

In connection with the reverse acquisition, the

Company incurred approximately

$110,000

for related transaction costs for the year ended

December 31, 2016,

which are included in general and administrative expenses in the accompanying consolidated statements of operations.

March 30, 2017,

the

Company issued to Mr. Victor Keen, Co-Chairman of the Board of Directors, a

convertible promissory note in a principal amount of

$250,000,

due

March 1, 2019 (

“Maturity Date”). The promissory note shall automatically convert into

eight

percent (

) of the fully diluted outstanding shares of common stock of the Company calculated after giving effect to (a) the exercise of all outstanding options, warrants or other rights to acquire shares of common stock of the Company, (b) the conversion of all outstanding convertible or exchangeable securities, and (c) after giving effect to the issuance of common stock upon conversion of this note (the “Conversion Shares”). The conversion shall

not

occur until both of the following

two

events shall have occurred (the “Conversion Event”): (i) the consummation of the Reverse Split by the Company as reflected in the Preliminary Information Statement filed with the Securities and Exchange Commission on

March 7, 2017,

and (ii) the conversion of all the Company’s issued and outstanding Series A Convertible Preferred Stock and Series B Convertible Preferred Stock into the Conversion Shares. If the Conversion Event has

not

occurred prior to the earlier to occur of the Maturity Date and the occurrence of an event of default, then this note shall

not

be automatically converted into the Conversion Shares and Mr. Victor Keen

may

elect, at his sole discretion, (i) to have the outstanding principal balance of this note converted into the Conversion Shares; or (ii) to declare the outstanding principal balance of this note, together with all accrued interest, be paid in accordance with the terms of the note. Such election

may

be made at any time on or following the Maturity Date or the occurrence of an event of default. This note is an unsecured obligation of the Company. The embedded conversion option was deemed to be a beneficial conversion feature because the active conversion price was less than the commitment date market price of the common stock. The dollar amount of the beneficial conversion feature is limited to the carrying value of the promissory note, so a

debt discount was recorded, with a corresponding credit to additional paid-in capital for the beneficial conversion feature. The debt discount will be amortized over the life of the debt and

Under the terms of the NDSU/RF Agreement, NDSU/RF granted Coretec an exclusive license to make, have made, use, sell, or any combination of the foregoing, Licensed Products and Licensed Processes in the Field of Use and the Licensed Territory as defined in the NDSU/RF Agreement.

Additionally, NDSU/RF granted to Licensee a limited exclusive

eighteen

-month option (the “Option Term”) to license Optioned Technologies' Patent Rights (“Optioned Technologies”), as described in the NDSU/RF Agreement. Licensee

may

only undertake technical, economic, and commercial evaluation of each optioned patent during the Option Term. Such evaluation by Licensee shall only be to determine if Licensee exercises its option and negotiates a license to such patent(s) as a Licensed Technology under the NDSU/RF Agreement and

not

to develop intellectual property or patents during the Option Term. Licensee agreed to actively and diligently evaluate Optioned Technologies to determine and report to NDSU/RF the status and progress toward the licensing of each patent listed in the NDSU/RF Agreement during the Option Term. If Licensee decides to

not

pursue any further evaluation of any patent or patent application of Optioned Technology Patent Rights in any quarter or during the previous quarter has

not

to exceed to

“LT On-going Expenses”) and each month thereafter during the term of the Agreement. The LT On-going Expenses are due monthly within

thirty

days of being invoiced. The LT Prior Expenses of

Beginning

April 1, 2016.

OT On-going Expenses of Optioned Technologies are to be reimbursed within

thirty

(

) days of being invoiced.

Licensee

may

terminate this NDSU/RF Agreement at any time by providing at least

six

(

) months written, unambiguous notice of such termination to NDSU/RF. Licensee shall remain obligated to pay all amounts due NDSU/RF through the effective date of the termination.

During the years ended

December 31, 2017

and

2016,

Coretec recognized expense of

$212,721

and

$136,420

respectively

under the terms of the NDSU/RF Agreement. As of

December 31, 2017,

the remaining balance of the LT Prior Expenses to be paid under the terms of the agreement is

$127,111.

As of

December 31, 2017,

and pursuant to the NDSU/RF Agreement, Coretec was in arrears on certain payment obligations in the amount of

$139,800.

Accordingly, as of

December 31, 2017,

Coretec would be considered in default under the NDSU/RF Agreement, because of the unpaid obligations, which could allow NDSU/RF to exercise various options under the NDSU/RF Agreement, including an option to terminate the agreement if we do

not

cure the default within

business days after receiving written notice by NDSU/RF. Although NDSU/RF provided a written notice on or around

February 7, 2018,

NDSU/RF subsequently retracted the notice and agreed to forbear from enforcing any defaults prior to

March 30, 2018.

Due to Coretec’s belief that certain obligations of NDSU/RF were unsatisfied, Coretec has actively communicated with NDSU/RF in order to determine what obligations are owed and what actions all parties are required to take, and will agree to take, in furtherance of the NDSU/RF Agreement. In connection with such objective, Coretec expects to send NDSU/RF a detailed communication setting forth, among other things, the basis for its belief that (i) the payment obligation was

not

due to NDSU/RF; and (ii) NDSU/RF does

not

have the right to enforce a default. As of the date of this report, there have been

legal proceedings initiated in connection with the NDSU/RF Agreement. However,

assurances can be made that the active communications between the parties will result in a resolution or that legal proceedings will

not

be initiated in the future.

he Company did

– Preferred Stock, Warrants and Options

The terms of the Series A Convertible Preferred Stock, Series B Convertible Preferred Stock

, Warrants and Options are as follows:

Series A Convertible Preferred Stock

A total of

500,000

shares of Series A Convertible Preferred Stock (the “Series A Preferred Stock”) have been authorized for issuance under the Certificate of Designation of Preferences, Rights and Limitation of Series A Convertible Preferred Stock of

the Company (the “Certificate of Designation”), which Certificate of Designation was filed with the Secretary of State of the State of Oklahoma on

December 11, 2013.

The shares of Series A Preferred Stock have a par value of

$0.0002

per share and a stated value of

$1.00

per share (the “Stated Value”) and shall receive a dividend of

of their Stated Value per annum payable or upon conversion or redemption of Series A Preferred at the option of the Corporation. We have

not

paid any cash or stock dividends to the holders of our Series A Preferred. As of

December 31, 2017,

dividends in arrears totaled approximately

$87,000.

Under the Certificate of Designation, the holders of the Series A Preferred Stock have the following rights, preferences and privileges:

The Series A Preferred Stock

may,

at the option of the Investor, be converted at any time after the

first

anniversary of the issuance of the Series A Preferred Stock or from time to time thereafter into

166,667

post-split shares of Common Stock that such investor is entitled to in proportion to the

500,000

shares of Series A Preferred so designated in the Certificate of Designation.

The Series A Preferred Stock will automatically be converted into Common Stock anytime the

post-split

-day average VWAP of the Company’s Common Stock prior to such conversion is equal to

$15.00

or more. Such mandatory conversion would be converted by the same method described above for discretionary conversions.

Except as otherwise required by law, the holders of shares of Series A Preferred Stock shall

not

have voting rights or powers.

In the event of any (i) liquidation, dissolution or winding up of the

Company, whether voluntary or involuntary, or ii) sale, merger, consolidation, reorganization or other transaction that results in a change of control of the Company, each holder of a share of Series A Preferred shall be entitled to receive, subject to prior preferences and other rights of any class or series of stock of the Company senior to the Series A Preferred, but prior and in preference to any distribution of any of the assets or surplus funds of the Company to holders of Common Stock, or any other class or series of stock of the Company junior to the Series A Preferred, an amount equal to the Stated Value plus accrued and unpaid dividends (as adjusted for any stock dividends, combinations or splits with respect to such shares) (the “Preference Amount”). After such payment has been made to the holders of Series A Preferred of the full Preference Amount to which such holders shall be entitled, the remaining net assets of the Company available for distribution, if any, shall be distributed pro rata among the holders of Common Stock. In the event the funds or assets legally available for distribution to the holders of Series A Preferred are insufficient to pay the Preference Amount, then all funds or assets available for distribution to the holders of capital stock shall be paid to the holders of Series A Preferred pro rata based on the full Preference Amount to which they are entitled.

The

Company

may

not

declare, pay or set aside any dividends on shares of any class or series of capital stock of the Company (other than dividends on shares of Common Stock payable in shares of Common Stock) unless the holders of the Series A Preferred Stock shall

first

receive, or simultaneously receive, a dividend on each outstanding share of Series A Preferred in an amount equal to the dividend per share that such holders would have received had they converted their shares of Series A Preferred into shares of Common Stock immediately prior to the record date for the declaration of the Common Stock dividend in an amount equal to the average VWAP during the

trading days prior to the date such dividend is due.

In regard to

the implications of the Exchange Transaction on Section

of the Series A Certificate of Designation (“COD”), the Company’s position is that a “Liquidity Event” as defined in Section

(b) of the COD, as the concept was intended by all the Company and investors purchasing the shares, has

not

occurred.

Series A Warrants

Each Unit under the Securities Purchase Agreement consists of warrants entitling the investor to purchase

fifty

(

)

pre-split shares of Common Stock for each share of Series A Preferred purchased by such investor in the Private Placement, at an initial pre-split exercise price per share of

$0.0055.

The exercise price and number of shares of Common Stock issuable under the warrants are subject to adjustments for stock dividends, splits, combinations and similar events. On or after the

first

anniversary of the issuance of the warrants and prior to close of business on the

fourth

anniversary of the issuance of the warrants, the warrants

may

be exercised at any time upon the election of the holder, provided however, that an investor

may

at any given time convert only up to that number of shares of Common Stock so that, upon conversion, the aggregate beneficial ownership of the Company’s Common Stock (calculated pursuant to Rule

13d

of the Securities Exchange Act of

1934,

as amended) of such investor and all persons affiliated with such investor, is

not

more than

4.99%

of the Company’s Common Stock then outstanding (subject to adjustment up to

9.99%

at the investor’s discretion upon

days’ prior notice). The Series A Warrants expired in

November 2017

and

January 2018,

four

years from date of issuance.

Series B Convertible Preferred Stock

March 22, 2016,

the Company filed with the Secretary of State of the State of Oklahoma a Certificate of Designation (the “Certificate of Designation”), setting for the Preferences, Rights and Limitation of the Company’s Series B Convertible Preferred Stock (the “Series B Preferred”). The Two Million (

2,000,000

) shares of Series B Preferred designated under the Certificate of Designation have a stated value of

$1.00

per share (the “Stated Value”). Under the Certificate of Designation, the holders of the Series B Preferred have the following rights, preferences and privileges:

The holders of Series B Preferred are

not

entitled to receive dividends but have voting rights equal to the number of shares of the

Company’s Common Stock into which their Series B Preferred can be converted, whether or

not

the shares are available for issuance.

At the option of the holder, Series B Preferred

may

be converted in whole or in part, from time to time, into

6.38

post-split shares of Common Stock. The Series B Preferred Stock will automatically be converted into Common Stock if (i) at any time the

day average VWAP of the Company’s Common Stock prior to such automatic conversion is equal to pre-split

$0.10

or more; or (ii) the Company enters into a transaction for which the Company enters into a share exchange agreement or agreement and plan of merger, which agreement is executed within

ninety

(

) days after the date of the Certificate of Designation and pursuant to which the Company thereafter becomes a consolidated company with another entity, and the Company issues equity securities of the Company. Such automatic conversion would be converted by the same method described above for discretionary conversions.

In the event of any i) liquidation, dissolution or winding up of the

Company, whether voluntary or involuntary, or ii) sale, merger, consolidation, reorganization or other transaction that results in a change of control of the Company, each holder of a share of Series B Preferred shall be entitled to receive, subject to prior preferences and other rights of any class or series of stock of the Company senior to the Series B Preferred, but prior and in preference to any distribution of any of the assets or surplus funds of the Company to holders of Common Stock, or any other class or series of stock of the Company junior to the Series B Preferred, an amount equal to the Stated Value (as adjusted for any stock dividends, combinations or splits with respect to such shares) (the “Preference Amount”). After such payment has been made to the holders of Series B Preferred of the full Preference Amount to which such holders shall be entitled, the remaining net assets of the Company available for distribution, if any, shall be distributed pro rata among the holders of Common Stock. In the event the funds or assets legally available for distribution to the holders of Series B Preferred are insufficient to pay the Preference Amount, then all funds or assets available for distribution to the holders of capital stock shall be paid to the holders of Series B Preferred pro rata based on the full Preference Amount to which they are entitled.

September 30, 2016,

the Company filed with the Secretary of State of the State of Oklahoma a Certificate of Amendment to the Certificate of Designation, increasing the number of authorized shares of Series B Preferred Stock from

The total number of shares of stock which may be purchased or granted directly by options, stock awards or restricted stock purchase offers, or purchased indirectly through exercise of options granted under the 2018 EIP shall not exceed fifteen million ( 15,000,000 ) shares.

Among the Recipients were (i) Doug Freitag, the Company’s former Chief Executive Officer, who received 322,154 shares of common stock in satisfaction of $41,880 owed to him for services he provided to the Company; (ii) Concordia Financial Group, the Company’s financial consultant, who received 230,770 shares of common stock satisfaction of $30,000 owed for services provided to the Company under the terms of the independent consulting agreement. License Agreement As of December 31, 2017, and pursuant to the NDSU/RF Agreement, Coretec was in arrears on certain payment obligations in the amount of $139,800. Accordingly, as of December 31, 2017, Coretec would be considered in default under the NDSU/RF Agreement, because of the unpaid obligations, which could allow NDSU/RF to exercise various options under the NDSU/RF Agreement, including an option to terminate the agreement if we do not cure the default within 10 business days after receiving written notice by NDSU/RF. Although NDSU/RF provided a written notice on or around February 7, 2018, NDSU/RF subsequently retracted the notice and agreed to forbear from enforcing any defaults prior to March 30, 2018. Due to Coretec’s belief that certain obligations of NDSU/RF were unsatisfied, Coretec has actively communicated with NDSU/RF in order to determine what obligations are owed and what actions all parties are required to take, and will agree to take, in furtherance of the NDSU/RF Agreement. In connection with such objective, Coretec expects to send NDSU/RF a detailed communication setting forth, among other things, the basis for its belief that (i) the payment obligation was not due to NDSU/RF; and (ii) NDSU/RF does not have the right to enforce a default. As of the date of this report, there have been no legal proceedings initiated in connection with the NDSU/RF Agreement. However, no assurances can be made that the active communications between the parties will result in a resolution or that legal proceedings will not be initiated in the future.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
