of the outbreak, the duration and effect of business disruptions and the short-term effects and ultimate effectiveness of the
travel restrictions, quarantines, social distancing requirements and business closures in the United States and other countries
to contain and treat the disease. While the potential economic impact caused by, and the duration of, COVID-19 may be difficult
to assess or predict, a widespread pandemic such as COVID-19 could result in significant disruption of global financial markets,
reducing the Company&rsquo;s ability to access capital, which could in the future negatively affect the Company&rsquo;s liquidity.
In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect the Company&rsquo;s
business and the value of its common stock.</FONT></P>

preparation of financial statements and the accompanying notes thereto, in conformity with generally accepted accounting principles
in the United States of America (&ldquo;GAAP&rdquo;), requires management to make estimates and assumptions that affect reported
amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements
and reported amounts of revenues and expenses during the respective reporting periods. Examples include the provision for bad
debt, sales returns and allowances, inventory obsolescence, useful lives of property and equipment, impairment of property and
equipment, income tax valuations and assumptions related to accrued advertising. When providing for the appropriate sales returns,
allowances, cash discounts and cooperative incentive promotion costs (&ldquo;sales allowances&rdquo;), we apply a uniform and
consistent method for making certain assumptions for estimating these provisions. These estimates and assumptions are based on
historical experience, current trends and other factors that management believes to be relevant at the time the financial statements
are prepared. Management reviews its accounting policies, assumptions, estimates and judgments on a quarterly basis. Actual results
could differ from those estimates.</FONT></P>

marketable debt securities are carried at fair value, with unrealized gains and losses included as a separate component of stockholders&rsquo;

short term investments in marketable debt securities, which carry maturity dates between one and three years from date of purchase
with interest rates of 1.875% - 2.750% during the first quarter of Fiscal 2020. For the three months ended March 31, 2020,
we reported unrealized gains of $11,000 and an accumulated unrealized income of $9,000. Unrealized gains and losses
are classified as other comprehensive income (loss) and the cost is determined on a specific identification basis. The following

review the carrying value of our long-lived assets with definite lives whenever events or changes in circumstances indicate that
the carrying amount of the assets may not be recoverable. When indicators of impairment exist, we determine whether the estimated
undiscounted sum of the future cash flows of such assets is less than their carrying amounts. If less, an impairment loss is recognized
in the amount, if any, by which the carrying amount of such assets exceeds their respective fair values. The determination of
fair value is based on quoted market prices in active markets, if available, or independent appraisals; sales price negotiations;
or projected future cash flows discounted at a rate determined by management to be commensurate with our business risk. The estimation
of fair value utilizing discounted forecasted cash flows includes significant judgments regarding assumptions of revenue, operating

competition; and general economic and business conditions, among other factors.</FONT></P>

observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets

utilize the asset and liability approach which requires the recognition of deferred tax assets and liabilities for the future

income to offset the temporary timing differences attributable to operations and the tax deductions attributable to option, warrant

utilize a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position

will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure
the tax benefit as the largest amount which is more than fifty percent likely of being realized upon ultimate settlement. Any
interest or penalties related to income taxes will be recorded as interest or administrative expense, respectively.</FONT></P>

September 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The ASU sets forth a &ldquo;current
expected credit loss&rdquo; (CECL) model which requires the Company to measure all expected credit losses for financial instruments
held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces
the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized
cost and applies to some off-balance sheet credit exposures. In February 2020, the FASB issued ASU 2020-02, Financial Instruments
- Credit Losses (Topic 326), which amends the effective date of the original pronouncement for smaller reporting companies. ASU
2016-13 and its amendments will be effective for the Company for interim and annual periods in fiscal years beginning after December

the three months ended March 31, 2020, net sales were $1.9 million as compared to $2.3 million for the three months ended March

of sales for the three months ended March 31, 2020 were $1.5 million as compared to $1.8 million for the three months ended March

decrease of 0.4% in gross margin from the prior period is principally due to fluctuations in our product mix shipped and pricing
fluctuations from period to period. Gross margins are generally influenced by fluctuations in quarter-to-quarter production volume,
fixed production costs and related overhead absorption, raw ingredient costs, inventory mark to market write-downs and timing
of shipments to customers.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">On November 12, 2019,
an action was filed in the United States District Court for the Eastern District of Texas against TK Supplements, Inc.,
one of our wholly-owned subsidiaries (&ldquo;TK Sub&rdquo;), asserting two class claims and alleging that, by sending plaintiff
text messages to his cellular telephone number without his prior express consent and notwithstanding its listing on the Do No
Call Registry, TK Sub violated the Telephone Consumer Protection Act, 47 U.S.C. &sect; 227(b)(3)(B) and 47 U.S.C. &sect; 227(c)(5).
Plaintiff seeks to represent a class of (i) all residents within the United States to whom TK Sub or its agents sent text messages
to the person&rsquo;s cellular telephone number in the past four years and (ii) all residents within the United States to whom
TK Sub or its agents placed two or more telemarketing phone calls to the person&rsquo;s residential telephone number that was
listed on the Do Not Call Registry in the past four years. On January 8, 2020, TK Supplements filed its Answer and Defenses to
the Complaint. We intend to defend this matter vigorously.</P>

    <PRPH:EscrowReceivableDescription contextRef="From2020-01-01to2020-03-31_custom_MylanandEscrowAgentMember_custom_EscrowAgreementMember">The terms of the Escrow Agreement provide that if, as of September 29, 2018, there were funds remaining in the escrow account, then the escrow account would be reduced by the difference, if a positive number, of (i) $2.5 million minus (ii) the aggregate amount of all escrow claims asserted by Mylan prior to this date that had either been paid out of the escrow account or were pending as of such date, and, within two business days of such date, the Escrow Agent would disburse such difference, if a positive number, to us. In addition, within two business days of March 29, 2019, the Escrow Agent was required to release any funds remaining in the escrow account to us minus any amounts being reserved for escrow claims asserted by Mylan prior to such date. Upon the resolution of any pending escrow claims, the Escrow Agent would then, within two business days of receipt of joint instructions or a final order from a court (as described in the Escrow Agreement) disburse such reserved amount to the parties entitled to such funds. As described below, in August 2018, Mylan asserted an indemnification claim against us, for a yet to be determined amount. Accordingly, the distributions were not released to us on September 29, 2018 or March 29, 2019.</PRPH:EscrowReceivableDescription>

The accompanying unaudited condensed&#13;consolidated financial statements have been prepared by management without audit and should be read in conjunction with our audited&#13;consolidated financial statements, including the notes thereto, appearing in our Annual Report on Form 10-K for the fiscal year&#13;ended December 31, 2019. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial&#13;position, consolidated results of operations and consolidated cash flows, for the periods indicated, have been made.

In&#13;addition, we are engaged in market activities for our TK Supplements&lt;sup&gt;&amp;#174;&lt;/sup&gt; product line of dietary supplements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 31.7pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Our sales are influenced&#13;by and subject to (i) the timing of acceptance of our TK Supplements&lt;sup&gt;&amp;#174;&lt;/sup&gt; products in the marketplace, and (ii) fluctuations&#13;in the timing of purchase and the ultimate level of demand for the OTC healthcare and cold remedy products that we manufacture&#13;for others, which are a function of the timing, length and severity of each cold season. Generally, a cold season is defined as&#13;the period from September to March when the incidence of the common cold rises as a consequence of the change in weather and other&#13;factors. We generally experience in the first, third and fourth quarter higher levels of net sales from our contract manufacturing&#13;of OTC healthcare and cold remedy products. Revenues are generally at their lowest levels in the second quarter when customer demand&#13;generally declines.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 31.7pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;As a consequence of the&#13;timing of acceptance of our TK Supplements&lt;sup&gt;&amp;#174;&lt;/sup&gt; products in the marketplace and the seasonality of our business, we&#13;realize variations in operating results and demand for working capital from quarter to quarter. As of March 31, 2020, we had working&#13;capital of approximately $8.4 million, including $0.8 million in marketable securities available for sale. We believe our current&#13;working capital at March 31, 2020 is at an acceptable and adequate level to support our business for at least the next twelve months.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Based on the Company&amp;#8217;s&#13;current assessment, the Company does not expect any material impact on its long-term liquidity due to the COVID-19 pandemic. However,&#13;the Company will continue to assess the effect of the pandemic on its operations. The extent to which the COVID-19 pandemic will&#13;impact the Company&amp;#8217;s business and operations will depend on future developments that are highly uncertain and cannot be predicted&#13;with confidence at this time, such as the ultimate geographic spread of the disease, the duration of the outbreak, the duration&#13;and effect of business disruptions and the short-term effects and ultimate effectiveness of the travel restrictions, quarantines,&#13;social distancing requirements and business closures in the United States and other countries to contain and treat the disease.&#13;While the potential economic impact caused by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread&#13;pandemic such as COVID-19 could result in significant disruption of global financial markets, reducing the Company&amp;#8217;s ability&#13;to access capital, which could in the future negatively affect the Company&amp;#8217;s liquidity. In addition, a recession or market&#13;correction resulting from the spread of COVID-19 could materially affect the Company&amp;#8217;s business and the value of its common&#13;stock.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Use of Estimates&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The preparation of financial&#13;statements and the accompanying notes thereto, in conformity with generally accepted accounting principles in the United States&#13;of America (&amp;#8220;GAAP&amp;#8221;), requires management to make estimates and assumptions that affect reported amounts of assets and&#13;liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of&#13;revenues and expenses during the respective reporting periods. Examples include the provision for bad debt, sales returns and allowances,&#13;inventory obsolescence, useful lives of property and equipment, impairment of property and equipment, income tax valuations and&#13;assumptions related to accrued advertising. When providing for the appropriate sales returns, allowances, cash discounts and cooperative&#13;incentive promotion costs (&amp;#8220;sales allowances&amp;#8221;), we apply a uniform and consistent method for making certain assumptions&#13;for estimating these provisions. These estimates and assumptions are based on historical experience, current trends and other factors&#13;that management believes to be relevant at the time the financial statements are prepared. Management reviews its accounting policies,&#13;assumptions, estimates and judgments on a quarterly basis. Actual results could differ from those estimates.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Cash and Cash Equivalents&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We consider all highly&#13;liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. Cash equivalents include&#13;cash on hand and monies invested in money market funds. The carrying amount approximates the fair market value due to the short-term&#13;maturity of these investments.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Marketable Debt Securities&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We have classified our&#13;investments in marketable debt securities as available-for-sale and as a current asset. Our investments in marketable debt securities&#13;are carried at fair value, with unrealized gains and losses included as a separate component of stockholders&amp;#8217; equity. Realized&#13;gains and losses from our marketable debt securities are recorded as interest income (expense). We initiated short term investments&#13;in marketable debt securities, which carry maturity dates between one and three years from date of purchase with interest rates&#13;of 1.875% - 2.750% during the first quarter of Fiscal 2020. For the three months ended March 31, 2020, we reported unrealized gains&#13;of $11,000 and an accumulated unrealized income of $9,000. Unrealized gains and losses are classified as other comprehensive income&#13;(loss) and the cost is determined on a specific identification basis. The following is a summary of the components of our marketable&#13;debt securities and the underlying fair value input level tier hierarchy (see long-lived assets below) (in thousands):&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

We have reviewed our property, plant and equipment for the three months ended March 31, 2020 and&#13;2019 and concluded there were no impairments or changes in useful lives.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Concentration of Risks&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Future revenues, costs,&#13;margins and profits will continue to be influenced by our ability to maintain our manufacturing availability and capacity together&#13;with our marketing and distribution capabilities and the regulatory requirements associated with the development of OTC consumer&#13;healthcare products, dietary supplements and other remedies in order to compete on a national level and/or international level.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Our business is subject&#13;to federal and state laws and regulations adopted for the health and safety of users of our products. The manufacturing and distribution&#13;of OTC healthcare and dietary supplement products are subject to regulations by various federal, state and local agencies, including&#13;the Food and Drug Administration (&amp;#8220;FDA&amp;#8221;) and, as applicable, the Homeopathic Pharmacopoeia of the United States.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Financial instruments that&#13;potentially subject us to significant concentrations of credit risk consist principally of cash investments, marketable securities,&#13;and trade accounts receivable. Our marketable securities are fixed income investments, which are highly liquid and can be readily&#13;purchased or sold through established markets.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We maintain cash and cash&#13;equivalents with certain major financial institutions. As of March 31, 2020, our cash and cash equivalents balance was $0.7 million&#13;and our bank balance was $0.8 million. Of the total bank balance, $0.3 million was covered by federal depository insurance and&#13;$0.5 million was uninsured at March 31, 2020.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Trade accounts receivable&#13;potentially subject us to credit concentrations from time-to-time as a consequence of the timing, payment pattern and ultimate&#13;purchase volumes or shipping schedules with our customers. We extend credit to our customers based upon an evaluation of the customer&amp;#8217;s&#13;financial condition and credit history and generally we do not require collateral. Our customers include consumer products companies&#13;and large national chain, regional, specialty and local retail stores. These credit concentrations may impact our overall exposure&#13;to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic, regulatory&#13;or other conditions that may impact the timing and collectability of amounts due to us. As a consequence of an evaluation of our&#13;customer&amp;#8217;s financial condition, payment patterns, balance due to us and other factors, we did not offset our account receivable&#13;with an allowance for bad debt at March 31, 2020 and December 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Long-lived Assets&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We review the carrying&#13;value of our long-lived assets with definite lives whenever events or changes in circumstances indicate that the carrying amount&#13;of the assets may not be recoverable. When indicators of impairment exist, we determine whether the estimated undiscounted sum&#13;of the future cash flows of such assets is less than their carrying amounts. If less, an impairment loss is recognized in the amount,&#13;if any, by which the carrying amount of such assets exceeds their respective fair values. The determination of fair value is based&#13;on quoted market prices in active markets, if available, or independent appraisals; sales price negotiations; or projected future&#13;cash flows discounted at a rate determined by management to be commensurate with our business risk. The estimation of fair value&#13;utilizing discounted forecasted cash flows includes significant judgments regarding assumptions of revenue, operating and marketing&#13;costs; selling and administrative expenses; interest rates; property and equipment additions and retirements; industry competition;&#13;and general economic and business conditions, among other factors.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Fair Value of Financial Instruments&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Fair value is based on&#13;the prices that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants&#13;at the measurement date. In order to increase consistency and comparability in fair value measurements, a three-tier fair value&#13;hierarchy prioritizes the inputs used to measure fair value. These tiers include: Level 1, defined as observable inputs such as&#13;quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly&#13;or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring&#13;an entity to develop its own assumptions.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Cash and cash equivalents,&#13;marketable securities, accounts receivable, assets held for sale, accounts payable, and accrued expenses are reflected in the consolidated&#13;financial statements at carrying value which approximates fair value.

We recognize revenue when performance obligations with our customers have&#13;been satisfied. At contract inception, evaluate the contract to determine if revenue should be recognized using the following five&#13;steps: (1) identify the contract with the customer; (2) identify the performance obligations; (3) determine the transaction price;&#13;(4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) the entity satisfies&#13;a performance obligation.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Performance Obligations&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We generate sales principally&#13;through two types of customers, contract manufacturing and retail customers. Sales from product shipments to contract manufacturing&#13;and retailer customers are recognized at the time ownership is transferred to the customer. Net sales from OTC healthcare contract&#13;manufacturing and retail dietary supplement product customers were $1.7 million and $0.2 million, respectively, for the three months&#13;ended March 31, 2020 and $2.1 million and $0.2 million, respectively, for the three months ended March 31, 2019. Revenue from retailer&#13;customers is reduced for trade promotions, estimated sales returns, cash discounts and other allowances in the same period as the&#13;related sales are recorded. No such allowance is applicable to our contract manufacturing customers. We make estimates of potential&#13;future product returns and other allowances related to current period revenue. We analyze historical returns, current trends, and&#13;changes in customer and consumer demand when evaluating the adequacy of the sales returns and other allowances.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;A performance obligation&#13;is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in accordance with&#13;ASC 606. A contract&amp;#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when,&#13;or as, the performance obligation is satisfied.

Fair values of stock options are determined through the use of the Black-Scholes option pricing model. The&#13;compensation cost is recognized as an expense over the requisite service period of the award, which usually coincides with the&#13;vesting period.

Stock options are exercisable during a period&#13;determined by us, but in no event later than ten years from the date granted. For the three months ended March 31, 2020 and 2019,&#13;we charged to operations $198,000 and $196,000, respectively, for share-based compensation expense for the aggregate fair value&#13;of stock grants issued and vested stock options earned.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Research and Development&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;R&amp;#38;D costs are charged&#13;to operations in the period incurred R&amp;#38;D costs incurred for the three months ended March 31, 2020 and 2019 from continuing&#13;operations were $59,000 and $94,000, respectively.

In estimating future tax consequences, we generally consider&#13;all expected future events other than enactments of changes in the tax law or rates. Until sufficient taxable income to offset&#13;the temporary timing differences attributable to operations and the tax deductions attributable to option, warrant and stock activities&#13;are assured, a valuation allowance equaling the total deferred tax asset is being provided.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We utilize a two-step approach&#13;to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining&#13;if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including&#13;resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount&#13;which is more than fifty percent likely of being realized upon ultimate settlement. Any interest or penalties related to income&#13;taxes will be recorded as interest or administrative expense, respectively.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;As a result of our losses&#13;from continuing operations, we have recorded a full valuation allowance against a net deferred tax asset. Additionally, we have&#13;not recorded a liability for unrecognized tax benefit.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: center"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;Recently Issued Accounting Standards,&#13;Not Yet Adopted&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;In September 2016, the&#13;FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The ASU sets forth a &amp;#8220;current expected credit&#13;loss&amp;#8221; (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the&#13;reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing&#13;incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies&#13;to some off-balance sheet credit exposures. In February 2020, the FASB issued ASU 2020-02, Financial Instruments - Credit Losses&#13;(Topic 326), which amends the effective date of the original pronouncement for smaller reporting companies. ASU 2016-13 and its&#13;amendments will be effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2022.&#13;The Company is currently assessing the impact of the adoption of this ASU on its financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;In December 2019, the&#13;FASB issued ASU No. 2019-12, &amp;#8220;Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (&amp;#8220;ASU 2019-12&amp;#8221;),&#13;which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to&#13;the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance&#13;is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption&#13;permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related&#13;disclosures.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

(formerly known as Meda Consumer Healthcare Inc.) (&amp;#8220;MCH&amp;#8221;) and Mylan Inc.&#13;(together with MCH, &amp;#8220;Mylan&amp;#8221;) under the asset purchase agreement pursuant to which we sold the Cold-EEZE&lt;sup&gt;&amp;#174;&#13;&lt;/sup&gt;business to Mylan, that may require us to make future payments to Mylan and other related persons for any damages incurred&#13;by Mylan or such related persons as a result of any breaches of our representations, warranties, covenants or agreements contained&#13;in the asset purchase agreement, or arising from the Retained Liabilities (as such term is defined in the asset purchase agreement)&#13;or certain third party claims specified in the asset purchase agreement. Generally, our representations and warranties survive&#13;for a period of 24 months from the closing date, which was March 29, 2017, other than certain fundamental representations which&#13;survive until the expiration of the applicable statute of limitations. There is a limited indemnification cap with respect to a&#13;majority of the Company&amp;#8217;s indemnification obligations under the asset purchase agreement with the exception of claims for&#13;actual fraud, the breach of any fundamental representations and certain other items, which have a larger indemnification cap (i.e.,&#13;the purchase price).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 9pt; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Pursuant to the terms of&#13;the asset purchase agreement, we, Mylan, and an escrow agent entered into an Escrow Agreement at closing, pursuant to which Mylan&#13;deposited $5 million of the aggregate purchase price for the Cold-EEZE&lt;sup&gt;&amp;#174; &lt;/sup&gt;business into an escrow account established&#13;with the Escrow Agent in order to satisfy, in whole or in part, certain of our indemnity obligations under the asset purchase agreement.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The terms of the Escrow&#13;Agreement provide that if, as of September 29, 2018, there were funds remaining in the escrow account, then the escrow account&#13;would be reduced by the difference, if a positive number, of (i) $2.5 million minus (ii) the aggregate amount of all escrow claims&#13;asserted by Mylan prior to this date that had either been paid out of the escrow account or were pending as of such date, and,&#13;within two business days of such date, the Escrow Agent would disburse such difference, if a positive number, to us. In addition,&#13;within two business days of March 29, 2019, the Escrow Agent was required to release any funds remaining in the escrow account&#13;to us minus any amounts being reserved for escrow claims asserted by Mylan prior to such date. Upon the resolution of any pending&#13;escrow claims, the Escrow Agent would then, within two business days of receipt of joint instructions or a final order from a court&#13;(as described in the Escrow Agreement) disburse such reserved amount to the parties entitled to such funds. As described below,&#13;in August 2018, Mylan asserted an indemnification claim against us, for a yet to be determined amount. Accordingly, the distributions&#13;were not released to us on September 29, 2018 or March 29, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;On May 31, 2018, we received&#13;notice of a claim for $800,000 in losses against the escrow amount. We resolved this claim pursuant to a settlement agreement,&#13;effective October 16, 2018, pursuant to which $160,000 of the funds held in escrow were released to Mylan. This expense is reflected&#13;in discontinued operations in the third quarter of 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;On August 2, 2018, we received&#13;notice of an indemnification claim from Mylan in relation to certain product advertising claims brought against Mylan related to&#13;certain Cold-EEZE&lt;sup&gt;&amp;#174;&lt;/sup&gt; products. Pursuant to the terms of the asset purchase agreement, we elected to assume the defense&#13;of these claims on behalf of Mylan, which we disputed and vigorously contested.

Unless terminated sooner by the parties, the Manufacturing Agreement will remain in&#13;effect until March 29, 2022. Thereafter, the Manufacturing Agreement may be renewed by Mylan for up to five successive one-year&#13;periods by providing notice of its intent to renew not less than 90 days prior to the expiration of the then-current term.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

Generally, a cold season is defined as&#13;the period from September to March when the incidence of the common cold rises as a consequence of the change in weather and other&#13;factors. We generally experience in the first, third and fourth quarter higher levels of net sales from our contract manufacturing&#13;of OTC healthcare and cold remedy products.

As of March 31, 2020, we had working&#13;capital of approximately $8.4 million, including $0.8 million in marketable securities available for sale. We believe our current&#13;working capital at March 31, 2020 is at an acceptable and adequate level to support our business for at least the next twelve months.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Based on the Company&amp;#8217;s&#13;current assessment, the Company does not expect any material impact on its long-term liquidity due to the COVID-19 pandemic. However,&#13;the Company will continue to assess the effect of the pandemic on its operations. The extent to which the COVID-19 pandemic will&#13;impact the Company&amp;#8217;s business and operations will depend on future developments that are highly uncertain and cannot be&#13;predicted with confidence at this time, such as the ultimate geographic spread of the disease, the duration of the outbreak, the&#13;duration and effect of business disruptions and the short-term effects and ultimate effectiveness of the travel restrictions,&#13;quarantines, social distancing requirements and business closures in the United States and other countries to contain and treat&#13;the disease. While the potential economic impact caused by, and the duration of, COVID-19 may be difficult to assess or predict,&#13;a widespread pandemic such as COVID-19 could result in significant disruption of global financial markets, reducing the Company&amp;#8217;s&#13;ability to access capital, which could in the future negatively affect the Company&amp;#8217;s liquidity. In addition, a recession&#13;or market correction resulting from the spread of COVID-19 could materially affect the Company&amp;#8217;s business and the value&#13;of its common stock.&lt;/p&gt;</PRPH:ProductInnovationSeasonalityOfBusinessAndLiquidityPolicyTextBlock>

Examples include the provision for bad debt, sales returns and&#13;allowances, inventory obsolescence, useful lives of property and equipment, impairment of property and equipment, income tax valuations&#13;and assumptions related to accrued advertising. When providing for the appropriate sales returns, allowances, cash discounts and&#13;cooperative incentive promotion costs (&amp;#8220;sales allowances&amp;#8221;), we apply a uniform and consistent method for making certain&#13;assumptions for estimating these provisions. These estimates and assumptions are based on historical experience, current trends&#13;and other factors that management believes to be relevant at the time the financial statements are prepared.

Realized&#13;gains and losses from our marketable debt securities are recorded as interest income (expense). We initiated short term investments&#13;in marketable debt securities, which carry maturity dates between one and three years from date of purchase with interest rates&#13;of 1.875% - 2.750% during the first quarter of Fiscal 2020.

We extend credit to our customers based upon an evaluation of the customer&amp;#8217;s&#13;financial condition and credit history and generally we do not require collateral. Our customers include consumer products companies&#13;and large national chain, regional, specialty and local retail stores. These credit concentrations may impact our overall exposure&#13;to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic, regulatory&#13;or other conditions that may impact the timing and collectability of amounts due to us. As a consequence of an evaluation of our&#13;customer&amp;#8217;s financial condition, payment patterns, balance due to us and other factors, we did not offset our account receivable&#13;with an allowance for bad debt at March 31, 2020 and December 31, 2019.&lt;/p&gt;</us-gaap:ConcentrationRiskCreditRisk>

When indicators of impairment exist, we determine whether the estimated undiscounted sum&#13;of the future cash flows of such assets is less than their carrying amounts. If less, an impairment loss is recognized in the&#13;amount, if any, by which the carrying amount of such assets exceeds their respective fair values. The determination of fair value&#13;is based on quoted market prices in active markets, if available, or independent appraisals; sales price negotiations; or projected&#13;future cash flows discounted at a rate determined by management to be commensurate with our business risk. The estimation of fair&#13;value utilizing discounted forecasted cash flows includes significant judgments regarding assumptions of revenue, operating and&#13;marketing costs; selling and administrative expenses; interest rates; property and equipment additions and retirements; industry&#13;competition; and general economic and business conditions, among other factors.&lt;/p&gt;</us-gaap:ImpairmentOrDisposalOfLongLivedAssetsPolicyTextBlock>

In order to increase consistency and comparability in fair value measurements, a three-tier fair value&#13;hierarchy prioritizes the inputs used to measure fair value. These tiers include: Level 1, defined as observable inputs such as&#13;quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly&#13;or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring&#13;an entity to develop its own assumptions.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Cash and cash equivalents,&#13;marketable securities, accounts receivable, assets held for sale, accounts payable, and accrued expenses are reflected in the consolidated&#13;financial statements at carrying value which approximates fair value.

We recognize revenue when performance obligations with our customers have&#13;been satisfied. At contract inception, evaluate the contract to determine if revenue should be recognized using the following five&#13;steps: (1) identify the contract with the customer; (2) identify the performance obligations; (3) determine the transaction price;&#13;(4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) the entity satisfies&#13;a performance obligation.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Performance Obligations&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We generate sales principally&#13;through two types of customers, contract manufacturing and retail customers. Sales from product shipments to contract manufacturing&#13;and retailer customers are recognized at the time ownership is transferred to the customer. Net sales from OTC healthcare contract&#13;manufacturing and retail dietary supplement product customers were $1.7 million and $0.2 million, respectively, for the three months&#13;ended March 31, 2020 and $2.1 million and $0.2 million, respectively, for the three months ended March 31, 2019. Revenue from retailer&#13;customers is reduced for trade promotions, estimated sales returns, cash discounts and other allowances in the same period as the&#13;related sales are recorded. No such allowance is applicable to our contract manufacturing customers. We make estimates of potential&#13;future product returns and other allowances related to current period revenue. We analyze historical returns, current trends, and&#13;changes in customer and consumer demand when evaluating the adequacy of the sales returns and other allowances.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;A performance obligation&#13;is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in accordance with&#13;ASC 606. A contract&amp;#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when,&#13;or as, the performance obligation is satisfied. The combined duties and responsibilities within each contract will be considered&#13;one single performance obligation under ASC 606 as these items would not be separately identifiable from each other promise in&#13;the contract and we provide a significant service of integrating the duties with other promises in the contracts.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;Transaction Price&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The transaction price is&#13;fixed based upon either (i) a combined Master Agreement and each related purchase order, or (ii) if there is no Master Agreement,&#13;the price per the individual purchase order received from each customer. The customers are invoiced at an agreed upon contractual&#13;price for each unit ordered and delivered by the Company and the R&amp;#38;D services are invoiced at the time the performance is completed.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The Company does not collect&#13;sales tax or other similar taxes from customers.

Our return policy for retailer customers accommodates returns for (i) discontinued products,&#13;(ii) store closings and (iii) products that have reached or exceeded their designated expiration date. We do not impose a period&#13;of time within which products must be returned. All requests for product returns must be submitted to us for pre-approval. The&#13;main components of our returns policy are: (i) we will accept returns that are due to damaged product that is un-saleable and such&#13;return request activity falls within an acceptable range, (ii) we will accept returns for products that have reached or exceeded&#13;designated expiration dates and (iii) we will accept returns in the event that we discontinue a product provided that the customer&#13;will have the right to return only such items that it purchased directly from us. We will not accept return requests pertaining&#13;to customer inventory &amp;#8220;Overstocking&amp;#8221; or &amp;#8220;Resets&amp;#8221;. We will accept return requests for only products in its&#13;intended package configuration. We reserve the right to terminate shipment of product to customers who have made unauthorized deductions&#13;contrary to our return policy or pursue other methods of reimbursement. We compensate the customer for authorized returns by means&#13;of a credit applied to amounts owed or to be owed and in the case of discontinued product only, also by way of an exchange. We&#13;do not have any significant product exchange history.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;We continue to recognize&#13;revenue from contract manufacturing and retail customers at a point in time as we have an enforceable right to payment for goods&#13;as products are shipped to customers.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Accrued advertising and&#13;other allowances from continuing operations as of March 31, 2020 included (i) $46,000 for estimated returns which is reported as&#13;a liability and (ii) $22,000 for cooperative and incentive promotion costs which is also reported as a liability.

As of December 31, 2019, deferred revenue was $214,000. Deferred revenues primarily consist of amounts that have been&#13;billed to or received from customers in advance of revenue recognition and prepayments received from customers in advance for implementation,&#13;maintenance and other services, as well as initial subscription fees. We recognize deferred revenues as revenues when the services&#13;are performed and the corresponding revenue recognition criteria are met. Customer prepayments are generally applied against invoices&#13;issued to customers when services are performed and billed.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0;

In estimating future tax consequences, we generally consider&#13;all expected future events other than enactments of changes in the tax law or rates.

The first step is to evaluate the tax position for recognition by determining&#13;if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including&#13;resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount&#13;which is more than fifty percent likely of being realized upon ultimate settlement. Any interest or penalties related to income&#13;taxes will be recorded as interest or administrative expense, respectively.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;As a result of our losses&#13;from continuing operations, we have recorded a full valuation allowance against a net deferred tax asset.

The ASU sets forth a &amp;#8220;current expected credit&#13;loss&amp;#8221; (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the&#13;reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing&#13;incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies&#13;to some off-balance sheet credit exposures. In February 2020, the FASB issued ASU 2020-02, Financial Instruments - Credit Losses&#13;(Topic 326), which amends the effective date of the original pronouncement for smaller reporting companies.

continuing and discontinued operations are computed by dividing the respective net loss attributable to common stockholders by
the weighted-average number of shares of our Common Stock outstanding for the period. Diluted loss per share reflects the potential
dilution that could occur if securities or other contracts to issue Common Stock were exercised or converted into Common Stock
or resulted in the issuance of Common Stock that shared in the earnings of the entity. Diluted loss per share also utilize the
treasury stock method which prescribes a theoretical buy-back of shares from the theoretical proceeds of all options and warrants
outstanding during the period. Options and warrants outstanding to acquire shares of our Common Stock at March 31, 2020 and 2019
were 3,082,000 and 2,950,000, respectively.</p>

March 31, 2020, dilutive loss per share were the same as basic earnings per share due to the exclusion of Common Stock in the
form of stock options (&#8220;Common Stock Equivalents&#8221;), which in a net loss position would have an anti-dilutive effect
on loss per share. For the three months ended March 31, 2020, there were 3,082,000 potential dilutive Common Stock Equivalents
that were excluded from the loss per share computation as a consequence of their anti-dilutive effect. For the three months ended
March 31, 2019, there were 2,950,000 potential dilutive Common Stock Equivalents that were excluded from the loss per share computation

maintain parity. Accordingly, the Compensation Committee of the board of directors, as required by the terms of the 2018 Stock

$2.00 per share, effective as of September 5, 2018, the date the special $1.00 special cash dividend was paid to the Company&#8217;s

2019, the date the $0.25 special cash dividend was paid to the Company&#8217;s stockholders. The exercise price of the CEO Option
was further reduced from $1.75 to $1.50 per share, effective as of December 12, 2019, the date another $0.25 special cash dividend

average period of 0.9 years.</p>

<td class="text">The terms of the Escrow Agreement provide that if, as of September 29, 2018, there were funds remaining in the escrow account, then the escrow account would be reduced by the difference, if a positive number, of (i) $2.5 million minus (ii) the aggregate amount of all escrow claims asserted by Mylan prior to this date that had either been paid out of the escrow account or were pending as of such date, and, within two business days of such date, the Escrow Agent would disburse such difference, if a positive number, to us. In addition, within two business days of March 29, 2019, the Escrow Agent was required to release any funds remaining in the escrow account to us minus any amounts being reserved for escrow claims asserted by Mylan prior to such date. Upon the resolution of any pending escrow claims, the Escrow Agent would then, within two business days of receipt of joint instructions or a final order from a court (as described in the Escrow Agreement) disburse such reserved amount to the parties entitled to such funds. As described below, in August 2018, Mylan asserted an indemnification claim against us, for a yet to be determined amount. Accordingly, the distributions were not released to us on September 29, 2018 or March 29, 2019.<span></span>

March 31, 2020 and 2019, our revenues have come principally from our OTC healthcare and dietary supplement contract manufacturing
business and sales to retail customers of dietary supplement product.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The unaudited condensed
consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial
statements and the rules of the Securities and Exchange Commission (&#8220;SEC&#8221;) applicable to interim financial statements,
and therefore do not include all disclosures that might normally be required for financial statements prepared in accordance with
accounting principles generally accepted in the United States of America (&#8220;GAAP&#8221;). The accompanying unaudited condensed
consolidated financial statements have been prepared by management without audit and should be read in conjunction with our audited
consolidated financial statements, including the notes thereto, appearing in our Annual Report on Form 10-K for the fiscal year
ended December 31, 2019. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial
position, consolidated results of operations and consolidated cash flows, for the periods indicated, have been made. The results
of operations for the three months ended March 31, 2020 are not necessarily indicative of operating results that may be achieved
over the course of the full year.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Our net sales are derived
principally from our contract manufacturing of OTC healthcare and our dietary supplement products sold in the United States. In
addition, we are engaged in market activities for our TK Supplements<sup>&#174;</sup> product line of dietary supplements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 31.7pt">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Our sales are influenced
by and subject to (i) the timing of acceptance of our TK Supplements<sup>&#174;</sup> products in the marketplace, and (ii) fluctuations
in the timing of purchase and the ultimate level of demand for the OTC healthcare and cold remedy products that we manufacture
for others, which are a function of the timing, length and severity of each cold season. Generally, a cold season is defined as
the period from September to March when the incidence of the common cold rises as a consequence of the change in weather and other
factors. We generally experience in the first, third and fourth quarter higher levels of net sales from our contract manufacturing
of OTC healthcare and cold remedy products. Revenues are generally at their lowest levels in the second quarter when customer demand
generally declines.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 31.7pt">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">As a consequence of the
timing of acceptance of our TK Supplements<sup>&#174;</sup> products in the marketplace and the seasonality of our business, we
realize variations in operating results and demand for working capital from quarter to quarter. As of March 31, 2020, we had working
capital of approximately $8.4 million, including $0.8 million in marketable securities available for sale. We believe our current
working capital at March 31, 2020 is at an acceptable and adequate level to support our business for at least the next twelve months.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Based on the Company&#8217;s
current assessment, the Company does not expect any material impact on its long-term liquidity due to the COVID-19 pandemic. However,
the Company will continue to assess the effect of the pandemic on its operations. The extent to which the COVID-19 pandemic will
impact the Company&#8217;s business and operations will depend on future developments that are highly uncertain and cannot be predicted
with confidence at this time, such as the ultimate geographic spread of the disease, the duration of the outbreak, the duration
and effect of business disruptions and the short-term effects and ultimate effectiveness of the travel restrictions, quarantines,
social distancing requirements and business closures in the United States and other countries to contain and treat the disease.
While the potential economic impact caused by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread
pandemic such as COVID-19 could result in significant disruption of global financial markets, reducing the Company&#8217;s ability
to access capital, which could in the future negatively affect the Company&#8217;s liquidity. In addition, a recession or market
correction resulting from the spread of COVID-19 could materially affect the Company&#8217;s business and the value of its common
stock.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b><i>Use of Estimates</i></b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The preparation of financial
statements and the accompanying notes thereto, in conformity with generally accepted accounting principles in the United States
of America (&#8220;GAAP&#8221;), requires management to make estimates and assumptions that affect reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of
revenues and expenses during the respective reporting periods. Examples include the provision for bad debt, sales returns and allowances,
inventory obsolescence, useful lives of property and equipment, impairment of property and equipment, income tax valuations and
assumptions related to accrued advertising. When providing for the appropriate sales returns, allowances, cash discounts and cooperative
incentive promotion costs (&#8220;sales allowances&#8221;), we apply a uniform and consistent method for making certain assumptions
for estimating these provisions. These estimates and assumptions are based on historical experience, current trends and other factors
that management believes to be relevant at the time the financial statements are prepared. Management reviews its accounting policies,
assumptions, estimates and judgments on a quarterly basis. Actual results could differ from those estimates.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 0.5in; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b><i>Cash and Cash Equivalents</i></b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We consider all highly
liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. Cash equivalents include
cash on hand and monies invested in money market funds. The carrying amount approximates the fair market value due to the short-term
maturity of these investments.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We have classified our
investments in marketable debt securities as available-for-sale and as a current asset. Our investments in marketable debt securities
are carried at fair value, with unrealized gains and losses included as a separate component of stockholders&#8217; equity. Realized
gains and losses from our marketable debt securities are recorded as interest income (expense). We initiated short term investments
in marketable debt securities, which carry maturity dates between one and three years from date of purchase with interest rates
of 1.875% - 2.750% during the first quarter of Fiscal 2020. For the three months ended March 31, 2020, we reported unrealized gains
of $11,000 and an accumulated unrealized income of $9,000. Unrealized gains and losses are classified as other comprehensive income
(loss) and the cost is determined on a specific identification basis. The following is a summary of the components of our marketable
debt securities and the underlying fair value input level tier hierarchy (see long-lived assets below) (in thousands):</p>

if any, by which the carrying amount of such assets exceeds their respective fair values. The determination of fair value is based
on quoted market prices in active markets, if available, or independent appraisals; sales price negotiations; or projected future
cash flows discounted at a rate determined by management to be commensurate with our business risk. The estimation of fair value
utilizing discounted forecasted cash flows includes significant judgments regarding assumptions of revenue, operating and marketing

reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing
incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We have indemnification
obligations to Mylan Consumer Healthcare Inc. (formerly known as Meda Consumer Healthcare Inc.) (&#8220;MCH&#8221;) and Mylan Inc.
(together with MCH, &#8220;Mylan&#8221;) under the asset purchase agreement pursuant to which we sold the Cold-EEZE<sup>&#174;
</sup>business to Mylan, that may require us to make future payments to Mylan and other related persons for any damages incurred
by Mylan or such related persons as a result of any breaches of our representations, warranties, covenants or agreements contained
in the asset purchase agreement, or arising from the Retained Liabilities (as such term is defined in the asset purchase agreement)
or certain third party claims specified in the asset purchase agreement. Generally, our representations and warranties survive
for a period of 24 months from the closing date, which was March 29, 2017, other than certain fundamental representations which
survive until the expiration of the applicable statute of limitations. There is a limited indemnification cap with respect to a
majority of the Company&#8217;s indemnification obligations under the asset purchase agreement with the exception of claims for
actual fraud, the breach of any fundamental representations and certain other items, which have a larger indemnification cap (i.e.,
the purchase price).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 9pt; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Pursuant to the terms of
the asset purchase agreement, we, Mylan, and an escrow agent entered into an Escrow Agreement at closing, pursuant to which Mylan
deposited $5 million of the aggregate purchase price for the Cold-EEZE<sup>&#174; </sup>business into an escrow account established
with the Escrow Agent in order to satisfy, in whole or in part, certain of our indemnity obligations under the asset purchase agreement.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The terms of the Escrow
Agreement provide that if, as of September 29, 2018, there were funds remaining in the escrow account, then the escrow account
would be reduced by the difference, if a positive number, of (i) $2.5 million minus (ii) the aggregate amount of all escrow claims
asserted by Mylan prior to this date that had either been paid out of the escrow account or were pending as of such date, and,
within two business days of such date, the Escrow Agent would disburse such difference, if a positive number, to us. In addition,
within two business days of March 29, 2019, the Escrow Agent was required to release any funds remaining in the escrow account
to us minus any amounts being reserved for escrow claims asserted by Mylan prior to such date. Upon the resolution of any pending
escrow claims, the Escrow Agent would then, within two business days of receipt of joint instructions or a final order from a court
(as described in the Escrow Agreement) disburse such reserved amount to the parties entitled to such funds. As described below,
in August 2018, Mylan asserted an indemnification claim against us, for a yet to be determined amount. Accordingly, the distributions
were not released to us on September 29, 2018 or March 29, 2019.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">On May 31, 2018, we received
notice of a claim for $800,000 in losses against the escrow amount. We resolved this claim pursuant to a settlement agreement,
effective October 16, 2018, pursuant to which $160,000 of the funds held in escrow were released to Mylan. This expense is reflected
in discontinued operations in the third quarter of 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">On August 2, 2018, we received
notice of an indemnification claim from Mylan in relation to certain product advertising claims brought against Mylan related to
certain Cold-EEZE<sup>&#174;</sup> products. Pursuant to the terms of the asset purchase agreement, we elected to assume the defense

an action was filed in the United States District Court for the Eastern District of Texas against TK Supplements, Inc., one of
our wholly-owned subsidiaries (&#8220;TK Sub&#8221;), asserting two class claims and alleging that, by sending plaintiff text
messages to his cellular telephone number without his prior express consent and notwithstanding its listing on the Do No Call
Registry, TK Sub violated the Telephone Consumer Protection Act, 47 U.S.C. &#167; 227(b)(3)(B) and 47 U.S.C. &#167; 227(c)(5).
Plaintiff seeks to represent a class of (i) all residents within the United States to whom TK Sub or its agents sent text messages
to the person&#8217;s cellular telephone number in the past four years and (ii) all residents within the United States to whom
TK Sub or its agents placed two or more telemarketing phone calls to the person&#8217;s residential telephone number that was
listed on the Do Not Call Registry in the past four years. On January 8, 2020, TK Supplements filed its Answer and Defenses to
the Complaint. We intend to defend this matter vigorously.</p><span></span>

by and subject to (i) the timing of acceptance of our TK Supplements<sup>&#174;</sup> products in the marketplace, and (ii) fluctuations
in the timing of purchase and the ultimate level of demand for the OTC healthcare and cold remedy products that we manufacture
for others, which are a function of the timing, length and severity of each cold season. Generally, a cold season is defined as
the period from September to March when the incidence of the common cold rises as a consequence of the change in weather and other
factors. We generally experience in the first, third and fourth quarter higher levels of net sales from our contract manufacturing
of OTC healthcare and cold remedy products. Revenues are generally at their lowest levels in the second quarter when customer demand
generally declines.</p>

timing of acceptance of our TK Supplements<sup>&#174;</sup> products in the marketplace and the seasonality of our business, we
realize variations in operating results and demand for working capital from quarter to quarter. As of March 31, 2020, we had working
capital of approximately $8.4 million, including $0.8 million in marketable securities available for sale. We believe our current

current assessment, the Company does not expect any material impact on its long-term liquidity due to the COVID-19 pandemic. However,
the Company will continue to assess the effect of the pandemic on its operations. The extent to which the COVID-19 pandemic will
impact the Company&#8217;s business and operations will depend on future developments that are highly uncertain and cannot be
predicted with confidence at this time, such as the ultimate geographic spread of the disease, the duration of the outbreak, the
duration and effect of business disruptions and the short-term effects and ultimate effectiveness of the travel restrictions,
quarantines, social distancing requirements and business closures in the United States and other countries to contain and treat
the disease. While the potential economic impact caused by, and the duration of, COVID-19 may be difficult to assess or predict,
a widespread pandemic such as COVID-19 could result in significant disruption of global financial markets, reducing the Company&#8217;s
ability to access capital, which could in the future negatively affect the Company&#8217;s liquidity. In addition, a recession
or market correction resulting from the spread of COVID-19 could materially affect the Company&#8217;s business and the value
of its common stock.</p><span></span>

statements and the accompanying notes thereto, in conformity with generally accepted accounting principles in the United States
of America (&#8220;GAAP&#8221;), requires management to make estimates and assumptions that affect reported amounts of assets
and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts
of revenues and expenses during the respective reporting periods. Examples include the provision for bad debt, sales returns and
allowances, inventory obsolescence, useful lives of property and equipment, impairment of property and equipment, income tax valuations
and assumptions related to accrued advertising. When providing for the appropriate sales returns, allowances, cash discounts and
cooperative incentive promotion costs (&#8220;sales allowances&#8221;), we apply a uniform and consistent method for making certain
assumptions for estimating these provisions. These estimates and assumptions are based on historical experience, current trends
and other factors that management believes to be relevant at the time the financial statements are prepared. Management reviews
its accounting policies, assumptions, estimates and judgments on a quarterly basis. Actual results could differ from those estimates.</p><span></span>

been satisfied. At contract inception, evaluate the contract to determine if revenue should be recognized using the following five
steps: (1) identify the contract with the customer; (2) identify the performance obligations; (3) determine the transaction price;
(4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) the entity satisfies
a performance obligation.</p>

through two types of customers, contract manufacturing and retail customers. Sales from product shipments to contract manufacturing
and retailer customers are recognized at the time ownership is transferred to the customer. Net sales from OTC healthcare contract
manufacturing and retail dietary supplement product customers were $1.7 million and $0.2 million, respectively, for the three months
ended March 31, 2020 and $2.1 million and $0.2 million, respectively, for the three months ended March 31, 2019. Revenue from retailer
customers is reduced for trade promotions, estimated sales returns, cash discounts and other allowances in the same period as the
related sales are recorded. No such allowance is applicable to our contract manufacturing customers. We make estimates of potential
future product returns and other allowances related to current period revenue. We analyze historical returns, current trends, and
changes in customer and consumer demand when evaluating the adequacy of the sales returns and other allowances.</p>

is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in accordance with
ASC 606. A contract&#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when,
or as, the performance obligation is satisfied. The combined duties and responsibilities within each contract will be considered
one single performance obligation under ASC 606 as these items would not be separately identifiable from each other promise in
the contract and we provide a significant service of integrating the duties with other promises in the contracts.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">We utilize a two-step approach
to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining
if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including
resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount
which is more than fifty percent likely of being realized upon ultimate settlement. Any interest or penalties related to income
taxes will be recorded as interest or administrative expense, respectively.</p>

FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The ASU sets forth a &#8220;current expected credit
loss&#8221; (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the
reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing
incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies
to some off-balance sheet credit exposures. In February 2020, the FASB issued ASU 2020-02, Financial Instruments - Credit Losses
(Topic 326), which amends the effective date of the original pronouncement for smaller reporting companies. ASU 2016-13 and its
amendments will be effective for the Company for interim and annual periods in fiscal years beginning after December 15, 2022.
The Company is currently assessing the impact of the adoption of this ASU on its financial statements.</p>

FASB issued ASU No. 2019-12, &#8220;Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (&#8220;ASU 2019-12&#8221;),
which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to
the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance
is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption
permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related
disclosures.</p><span></span>
