The Company has not received any notice or obtained any Knowledge of circumstances indicating that it will not be able to renew its existing insurance coverage (modified to the extent deemed prudent and customary by the management of the Company) as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that is commercially reasonable and not reasonably likely to result in a Material Adverse Effect.

(s) Employee Relations. The Company believes that its relations with its employees are good. No executive officer of the Company (as defined in Rule 501(f) of the 0000 Xxx) has notified the Company that such officer intends to leave the Company or otherwise terminate such officer's employment with the Company. No executive officer of the Company, to the Knowledge of the Company, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any restrictive covenant to which the Company and such executive are parties, and, to the Knowledge of the Company, the continued employment of each such executive officer does not subject the Company to any liability with respect to any of the foregoing matters. The Company is in compliance with all federal, state, local and foreign laws and regulations respecting employment and employment practices, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

(t) Title. Except as described in or contemplated by the SEC Documents, the Company has good and marketable title to all personal property owned by it which is material to its business, in each case free and clear of all liens, encumbrances and defects except such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company. Any real property and facilities held under lease by the Company are held under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company. The Company owns no real property.

(u) Intellectual Property Rights. The Company owns or licenses all the proprietary rights ("Intellectual Property Rights") which are necessary for the business of the Company as now conducted, except to the extent that failure to do so would not reasonably be expected to have a Material Adverse Effect. Except for any infringement, claim, action, proceeding, or other circumstance that would not reasonably be expected to have a Material Adverse Effect, the Company does not have any Knowledge of (i) any infringement by the Company of Intellectual Property Rights of others, (ii) there is no claim, action or proceeding being made, brought or threatened against the Company regarding its Intellectual Property Rights, (iii) any facts or circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings. The Company has taken commercially reasonable measures to protect the secrecy, confidentiality and value of all of its Intellectual Property Rights.

To the Knowledge of the Company, the Company (i) is in compliance with any and all Environmental Laws (as hereinafter defined), (ii) has received all permits, licenses or other approvals required of it under applicable Environmental Laws to conduct its business and (iii) is in compliance with all terms and conditions of any such permit, license or approval where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply could be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect. The term "Environmental Laws" means all federal, state or local laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, "Hazardous Materials") into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees, demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder.

(w) Tax Status. The Company (i) has made or timely filed all federal and material state income and other tax returns, reports and declarations required by any jurisdiction to which it is subject, (ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on such returns, reports and declarations, except those being contested in good faith and (iii) has set aside on its books provision reasonably adequate for the payment of any taxes payable for periods subsequent to the periods to which such returns, reports or declarations apply. To the Knowledge of the Company, there are no unpaid taxes in any material amount claimed to be due and payable by the taxing authority of any jurisdiction and no factual basis for any such claim.

(x) Internal Accounting and Disclosure Controls. The Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management's general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles (GAAP) and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management's general or specific authorization and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any difference. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-14 under the 0000 Xxx) that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act (i) is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the SEC, and (ii) is accumulated and communicated to the Company’s management, including its principal executive officer or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure.

(y) Off Balance Sheet Arrangements. There is no transaction, arrangement, or other relationship between the Company and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Company in its 1934 Act filings and is not so disclosed and that would be reasonably likely to have a Material Adverse Effect.

(z) Transfer Taxes. On the Closing Date, all stock transfer or other taxes (other than income or similar taxes) which are required to be paid in connection with the sale and transfer of the Securities to be sold to the Buyer hereunder will be, or will have been, fully paid or provided for by the Company, and all laws imposing such taxes will be or will have been complied with.

(aa) Disclosure. The Company confirms that, with the exception of the transactions contemplated by this Agreement, neither it nor, to the Knowledge of the Company, any other Person acting on its behalf has provided the Buyer or its agents or counsel with any information that constitutes material, nonpublic information. The Company understands and confirms that the Buyer will rely on the foregoing representations in effecting transactions in securities of the Company. All disclosure provided by the Company to the Buyer regarding the Company, its business and the transactions contemplated hereby, including the Schedules to this Agreement, furnished by or on behalf of the Company are true and correct and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. To the Knowledge of the Company, no event or circumstance has occurred or information exists with respect to the Company or any Subsidiary or either of its or their respective business, properties, operations or financial conditions, which, under applicable law, rule or regulation, requires public disclosure or announcement by the Company but which has not been so publicly announced or disclosed (assuming for this purpose that the Company's reports filed under the 1934 Act are being incorporated into an effective registration statement filed by the Company under the 1933 Act). The Company acknowledges and agrees that the Buyer does not make and has not made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in the Transaction Documents.

(bb) No Implied Representations. All of the Company’s representations and warranties are contained in this Agreement, and no other representations or warranties by the Company shall be implied.

COVENANTS.

(a) Commercially Reasonable Efforts. Each party shall use its commercially reasonable efforts timely to satisfy each of the covenants and the conditions to be satisfied by it as provided in Sections 5, 6 and 7 of this Agreement.

(b) Form D and Blue Sky. The Company agrees to file a Form D with respect to the Securities as required under Regulation D. The Company, on or before the first Closing Date, shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for sale to the Buyer pursuant to this Agreement under applicable securities or "Blue Sky" laws of the states of the United States (or to obtain an exemption from such qualification). The Company shall make all filings and reports relating to the offer and sale of the Securities required under applicable securities or "Blue Sky" laws of the states of the United States only in such jurisdictions as Buyer shall reasonably request following the Closing Date applicable to such Buyer.

(c) Reporting Status. Until the date which is the later of the date on which (i) the Investor (as defined in the Registration Rights Agreement) shall have sold all the Conversion Shares and Warrant Shares and the Preferred Shares and Warrants are no longer outstanding or (ii) the Company is no longer obligated under the Registration Rights Agreement to maintain the registration statement filed thereunder (the "Reporting Period"), the Company shall timely file all reports required to be filed with the SEC pursuant to the 1934 Act, and the Company shall not terminate its status as an issuer required to file reports under the 1934 Act even if the 1934 Act or the rules and regulations thereunder would otherwise permit such termination.

(d) Financial Information. At an Investor's written request, the Company agrees to send the following to any requesting Investor during the Reporting Period, within two (2) Business Days after such written request, unless it is filed with the SEC and available to the public through the SEC's XXXXX system: (i) a copy of its Annual Reports on Form 10-K, its Quarterly Reports on Form 10-Q, any Current Reports on Form 8-K and any registration statements (other than on Form S-8) or amendments filed pursuant to the 1933 Act, and (ii) copies of any notices and other information made available or given to the stockholders of the Company generally. As used herein, "Business Day" means any day other than Saturday, Sunday or other day on which the Primary Market or commercial banks in The City of New York are authorized or required by law to remain closed.

(e) Listing. The Company shall use commercially reasonable efforts to maintain the Common Stock's listing on NASDAQ. If after using commercially reasonable efforts the Company is unable to maintain such listing on NASDAQ, the Company shall use commercially reasonable efforts to provide that the Common Stock is quoted for trading on the over-the-counter market.

(f) Disclosure of Transactions and Other Material Information. The Company shall, on or before 8:30 a.m., New York City Time, no later than the first Business Day after the first Closing Date, issue a press release (the "Press Release") disclosing the material terms of the transactions contemplated hereby. The Company shall provide the Buyer an advance copy of the Press Release and agrees to consider comments that the Buyer may provide but shall nevertheless be entitled to make such disclosure as it deems appropriate to meet its disclosure obligations under the 1934 Act. On or before 8:30 a.m., New York City Time, no later than the third Business Day following the first Closing Date, the Company shall file a Current Report on Form 8-K describing the terms of the transactions contemplated by the Transaction Documents in the form required by the 1934 Act (the "8-K Filing"). From and after the issuance of the Press Release, the Company shall ensure that the Buyer shall not be in possession of any material, nonpublic information received from the Company or any of its respective officers, directors, employees or agents, that is not disclosed in the Press Release. The Company shall not, and shall cause each of its officers, directors, employees and agents not to, provide the Buyer with any material, nonpublic information regarding the Company from and after the filing of the Press Release without the express written consent of the Buyer pursuant to a Confidentiality and Nondisclosure Agreement.

(g) Conduct of Business. The Company shall use commercially reasonable efforts to conduct its business to avoid violations of any law, ordinance or regulation of any governmental entity, except where such violations would not, either individually or in the aggregate, be reasonably expected to result in a Material Adverse Effect.

(h) Reservation of Shares. The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in such amount as may then be required to fulfill its obligations in full under the Transaction Documents (the "Required Minimum"). If, on any date, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less than the Required Minimum (minus the number of shares of Common Stock previously issued pursuant to the Transaction Documents), then the Board of Directors shall use commercially reasonable efforts to amend the Company’s certificate or articles of incorporation to increase the number of authorized but unissued shares of Common Stock to at least the Required Minimum at such time (minus the number of shares of Common Stock previously issued pursuant to the Transaction Documents), as soon as possible and in any event not later than the 120th day after such date; provided that the Company will not be required at any time to authorize a number of shares of Common Stock greater than the maximum remaining number of shares of Common Stock that could possibly be issued after such time pursuant to the Transaction Documents.

5. TRANSFER RESTRICTIONS; TRANSFER AGENT INSTRUCTIONS.

(a) Transfer Restrictions. If (i) all or any Preferred Shares are converted at a time when there is an effective registration statement to cover the issuance or resale of the Conversion Shares underlying the Preferred Shares or Rule 144 is available for resale of such Conversion Shares underlying the Preferred Shares without volume or manner of sale restrictions, the Conversion Shares underlying the Preferred Shares issued pursuant to any such conversion shall be issued free of all legends, provided that, in the case of legend-free issuance in reliance on Rule 144, the Holder provides a representation letter in the form and substance reasonably acceptable to the Company that such Conversion Shares may be issued without a restrictive legend, and (ii) all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the issuance or resale of the Warrant Shares or if the Warrant is exercised via cashless exercise and the applicable non-affiliate holding period under Rule 144 has been met, the Warrant Shares issued pursuant to any such exercise shall be issued free of all legends, provided that, in the case of legend-free issuance in reliance on Rule 144, the Holder provides a representation letter in the form and substance reasonably acceptable to the Company that such Warrant Shares may be issued without a restrictive legend.

(b) Breach. The Company acknowledges that a breach by it of its obligations under this Section 5 will cause irreparable harm to the Buyer. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5, that the Buyer shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

6. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

The obligation of the Company hereunder to issue and sell the Units to a Buyer at the Closing is subject to the satisfaction by such Buyer, at or before the first Closing Date, of each of the following conditions, provided that these conditions are for the Company's sole benefit and may be waived by the Company at any time in its sole discretion by providing such Buyer with prior written notice thereof:

(c) The representations and warranties of such Buyer shall be true and correct in all material respects as of the date when made and as of the Closing Date applicable to such Buyer as though made at that time (except for representations and warranties that speak as of a specific date), and such Buyer shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by such Buyer at or prior to the Closing Date applicable to such Buyer.

9. MISCELLANEOUS.

All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Delaware. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the State of Delaware for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper.

(i) Survival. Unless this Agreement is terminated under Section 8, the representations and warranties of the Company and the Buyer contained in Sections 2 and 3, the agreements and covenants set forth in Sections 4, 5 and 9 shall survive the Closing and the delivery and exercise of Securities, as applicable.

Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

(k) Indemnification. In consideration of the Buyer's execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company's other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless the Buyer, any affiliate of Buyer and each of their respective partners, members, officers, directors, employees and investors and any of the foregoing Persons' accounting and legal representatives retained in connection with the transactions contemplated by this Agreement (collectively, the "Indemnitees") from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys' fees and disbursements (the "Indemnified Liabilities"), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or any other certificate, instrument or document contemplated thereby, or (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any certificate, instrument or document contemplated thereby. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section 9(k) shall be the same as those set forth in Section 6 of the Registration Rights Agreement.

(l) Participation in Future Financing.

(i) During the period ending on the first anniversary of this Agreement, upon any issuance by the Company of Common Stock, Common Stock equivalents, or a combination thereof for cash consideration in a bona fide capital raising transaction (a “Subsequent Financing”), each Buyer shall have the right to participate in the Subsequent Financing to maintain the same Beneficial Ownership Percentage (as defined below) immediately after the Subsequent Financing that such Buyer had immediately prior to the Subsequent Financing. This participation right entitles the Buyer to participate in the Subsequent Financing on the same terms, conditions and price provided for in the Subsequent Financing. The Company shall use commercially reasonable efforts to structure such Subsequent Financing to accommodate investments from Buyers who may wish to remain within the Beneficial Ownership Limitation as defined in the Preferred Stock Designation of Preferences, Rights and Limitations and the Warrants (i.e., by offering common stock equivalents to Buyers that would not cause such Buyers to exceed their Beneficial Ownership Limitation).

(ii) At least six (6) trading days prior to the closing of the Subsequent Financing, the Company shall deliver to each Buyer a written notice of its intention to effect the Subsequent Financing (“Pre-Notice”), which Pre-Notice shall ask each Buyer if it wants to review the details of such financing (such additional notice, a “Subsequent Financing Notice”). Upon the request of a Buyer, the Company shall promptly, but no later than one (1) trading day after such request, deliver a Subsequent Financing Notice to such Buyer. The Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder and the Person or Persons through or with whom such Subsequent Financing is proposed to be effected and shall include a term sheet or similar document relating thereto as an attachment.

(iii) Any Buyer desiring to participate in such Subsequent Financing must provide written notice to the Company by not later than 5:30 p.m. (New York City time) on the fifth (5th) trading day after all Buyers have received the Pre-Notice that such Buyer is willing to participate in the Subsequent Financing, the amount of such Buyer’s participation, and representing and warranting that such Buyer has such funds ready, willing, and available for investment on the terms set forth in the Subsequent Financing Notice. If the Company receives no such notice from a Buyer as of such fifth (5th) trading day, such Buyer shall be deemed to have notified the Company that it does not elect to participate. At any time on or after 5:30 p.m. (New York City time) on the fifth (5th) trading day after all of the Buyers have received the Pre-Notice, the Company may effect the Subsequent Financing on the terms and with the Person(s) set forth in the Subsequent Financing Notice.

(iv) To the extent one or more Buyers decline all or part of their participation right under this Section 9(l), then the Company shall offer the securities purchasable under such declined participation right (the "Refused Securities"), to each Buyer that elected to participate in the Subsequent Financing to the maximum amount originally allocated to such Buyer (each such Buyer, referred to as an "Eligible Buyer" and such offer of the Refused Securities, referred to as the "Subsequent Financing Re-allocation"). Each Eligible Buyer shall be entitled to participate in the Subsequent Financing Re-allocation on a pro rata basis based on such Eligible Buyer’s participation (expressed as a percent) in the original offering provided under this Agreement. The Company shall effect the Subsequent Financing Re-allocation, if any, by providing a notice (the "Re-allocation Notice") to each Eligible Buyer not later than one (1) trading day prior to closing of the Subsequent Financing, and such notice shall set forth the number of Refused Securities offered to such Eligible Buyer. Any Eligible Buyer desiring to purchase any Refused Securities offered to them under the Subsequent Financing Re-allocation must provide written notice to the Company by not later than 10:00 a.m. on next trading day after the Company provides the Re-allocation Notice to the Eligible Buyers. If the Company does not receive a written notice from an Eligible Buyer by such time, such Eligible Buyer shall be deemed to have notified the Company that it does not elect to participate in the Subsequent Financing Re-allocation.

(v) For the avoidance of doubt and notwithstanding the foregoing, this Section 9(l) shall not apply in respect of (1) any transactions pursuant to that certain At-The-Market Equity Offering Sales Agreement dated as of February 11, 2013, as amended from time to time, between the Company and Xxxxxx, Xxxxxxxx & Company, Incorporated, (2) the issuance of shares of Common Stock, options to acquire shares of Common Stock or other awards granted pursuant to the Company’s benefit plans, as such plans may be amended, (3) the issuance of shares of Common Stock upon the exercise of any such options or other awards, (4) the issuance of shares of Common Stock pursuant to any options, warrants or convertible instrument outstanding as of the date of this Agreement, or the issuance in a Subsequent Financing of any shares of convertible preferred stock and warrants to purchase Common Stock pursuant to a stock purchase agreement in an amount of up to $2 million, (5) the issuance of up to 1 million shares of Common Stock to consultants or other service providers of the Company in consideration for services rendered, or (6) the issuance of Common Stock or Common Stock equivalents, including convertible instruments (and issuance of Common Stock pursuant to the terms of such convertible instrument) in connection with strategic alliances involving the Company and other entities, including, without limitation, joint venture, co-marketing, co-development or other collaboration arrangements.

(vi) For the purposes of this Section 9(l), Beneficial Ownership Percentage of each Buyer shall be calculated on a partially diluted basis, without regard to any beneficial ownership limitation provisions applicable to the Buyer, by dividing the sum of (1) the number of shares of Common Stock held by such Buyer, plus (2) the number of shares of Common Stock issuable upon conversion of all shares of convertible preferred stock of the Company held by such Buyer, and plus (3) the number of shares of Common Stock issuable upon exercise of warrants held by such Buyer with respect to the exercise price of which has been fully paid, by the sum of (A) the number of shares of common stock outstanding, plus (B) the number of shares of Common Stock issuable upon conversion of all shares of convertible preferred stock of the Company, plus (C) the number of shares of Common Stock issuable upon exercise of warrants the exercise price of which has been fully paid.

(m) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(n) Remedies. The Buyer shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law.

Correspondence re: potential Nasdaq delisting

On May 19, 2016, Windtree Therapeutics, Inc. (the “Company”) received a notification letter from the Listing Qualifications Department of The NASDAQ Stock Market (“Nasdaq”) notifying the Company that it is no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires listed companies to maintain stockholders’ equity of at least $2,500,000. In the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2016, the Company reported stockholders’ equity of ($4,977,000), which is below the minimum stockholders’ equity required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1). Further, as of May 19, 2016, the Company had not met the alternative compliance standards under Nasdaq Listing Rule 5550(b) of (i) a market value of listed securities of at least $35,000,000, or (ii) net income of $500,000 from continuing operations.

The Company submitted its plan to regain compliance with the Nasdaq Listing Rule on July 5, 2016 and, on July 12, 2016, the Staff notified the Company that it has determined to grant the Company an extension until November 15, 2016 to evidence compliance with the Minimum Stockholders’ Equity Rule. Under the terms of the extension, the Company was required to regain compliance with the Minimum Stockholders’ Equity Rule no later than November 15, 2016. The Company failed to regain compliance on o before November 15, 2016

On November 16, 2016, the Company received a written notice from the Listing Qualifications Department of Nasdaq notifying the Company that it had not met the terms of the extension and as a result, the Company’s common stock was subject to delisting from Nasdaq. The Company requested a hearing before a Hearings Panel (the “Panel”) pursuant to the procedures set forth in Nasdaq Listing Rule 5800 Series, which automatically stayed the delisting of the Company’s common stock pending the issuance of the Panel’s decision.

The Company submitted to Nasdaq its plan to regain compliance and various other documents and appeared before the Panel on January 12, 2017.

On January 18, 2017, the Company was notified by Nasdaq that the Panel had determined to allow the Company’s listing on Nasdaq to continue until May 15, 2017. During the extension, the Company is required to provide the Panel interim reports of its progress toward regaining compliance. The Panel will evaluate each of the Company’s reports and may delist the Company if it fails to demonstrate a reasonable likelihood of regaining compliance on or before May 15, 2017. Should the Company fail to demonstrate full compliance with the minimum $2.5 million stockholders’ equity requirement by May 15, 2017, the Panel will issue a final delist determination and the Company will be suspended from trading on Nasdaq
