information unless such information is disclosed to the public prior to or promptly following such disclosure to the Buyer. Neither such inquiries nor any other due diligence investigation conducted by Buyer or any of its advisors or representatives

 e. Governmental Review. The Buyer understands that no United States federal or state agency or any other government or
governmental agency has passed upon or made any recommendation or endorsement of the Securities.

The Buyer understands that (i) except as provided in the Registration Rights Agreement, the sale or re-sale of the Securities has not been and is not being registered under the 1933 Act or any applicable state securities laws, and the
Securities may not be transferred unless (a) the Securities are sold pursuant to an effective registration statement under the 1933 Act, (b) the Buyer shall have delivered to the Company an opinion of counsel that shall be in form,
substance and scope customary for opinions of counsel in comparable transactions to the effect that the Securities to be sold or transferred may be sold or transferred pursuant to an exemption from such registration, which opinion shall be accepted
by the Company, (c) the Securities are sold or transferred to an “affiliate” (as defined in Rule 144 promulgated under the 1933 Act (or a successor rule) (“Rule 144”)) of the Buyer who agrees to sell or otherwise
transfer the Securities only in accordance with this Section 2(f) and who is an Accredited Investor, (d) the Securities are sold pursuant to Rule 144, or (e) the Securities are sold pursuant to Regulation S under the 1933 Act (or a
successor rule) (“Regulation S”), and the Buyer shall have delivered to the Company an opinion of counsel that shall be in form, substance and scope customary for opinions of counsel in corporate transactions, which opinion shall be
accepted by the Company; (ii) any sale of such Securities made in reliance on Rule 144 may be made only in accordance with the terms of said Rule and further, if said Rule is not applicable, any re-sale of such Securities under circumstances in
which the seller (or the person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC
thereunder; and (iii) neither the Company nor any other person is under any obligation to register such Securities under the 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder (in each
case, other than pursuant to the Registration Rights Agreement). Notwithstanding the foregoing or anything else 

  

 3 

 
contained herein to the contrary, the Securities may be pledged as collateral in connection with a bona fide margin account or other lending
arrangement. In the event that the Company does not accept the opinion of counsel provided by the Buyer with respect to the transfer of Securities pursuant to an exemption from registration, such as Rule 144 or Regulation S, within three
(3) business days of delivery of the opinion to the Company, the Company shall pay to the Buyer liquidated damages of three percent (3%) of the outstanding amount of the Debentures per month plus accrued and unpaid interest on the
Debentures, prorated for partial months, in cash or shares at the option of the Company (“Standard Liquidated Damages Amount”). If the Company elects to pay the Standard Liquidated Damages Amount in shares of Common Stock, such
shares shall be issued at the Conversion Price at the time of payment. Notwithstanding anything herein to the contrary, in the event the Company has to pay the Standards Liquidated Damages Amount pursuant to any provision of this Agreement, the
Buyers shall first have to give the Company advance written notice of such breach and in such event, the Company shall have 30 days from the receipt of such notice to cure such breach before the Standard Liquidated Damages Amount shall be due and
payable to the Buyers. 
 g. Legends. The Buyer understands that the Debentures and the Warrants and, until such time as the
Conversion Shares and Warrant Shares have been registered under the 1933 Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant to Rule 144 or Regulation S without any restriction as to the number of securities as
of a particular date that can then be immediately sold, the Conversion Shares and Warrant Shares may bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of the certificates for such
Securities): 
 “The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended.
The securities may not be sold, transferred or assigned in the absence of an effective registration statement for the securities under said Act, or an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable
transactions, that registration is not required under said Act or unless sold pursuant to Rule 144 or Regulation S under said Act.” 
 The legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of any Security upon which it is stamped, if, unless otherwise required by applicable state securities laws,
(a) such Security is registered for sale under an effective registration statement filed under the 1933 Act or otherwise may be sold pursuant to Rule 144 or Regulation S without any restriction as to the number of securities as of a particular
date that can then be immediately sold, or (b) such holder provides the Company with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer
of such Security may be made without registration under the 1933 Act, which opinion shall be accepted by the Company so that the sale or transfer is effected or (c) such holder provides the Company with reasonable assurances that such Security
can be sold pursuant to Rule 144 or Regulation S. The Buyer agrees to sell all Securities, including those represented by a certificate(s) from which the legend has been removed, in compliance with applicable prospectus delivery requirements, if
any.

affected, except for possible defaults as would not, individually or in the aggregate, have a Material Adverse Effect. The businesses of the Company and its Subsidiaries, if any, are not being conducted, and shall not be conducted so long as a Buyer

thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in

Company or of a Subsidiary with respect to any Intellectual Property necessary to enable it to conduct its business as now operated (and, except as set forth in Schedule 3(j) hereof, to the best of the Company’s knowledge, as presently
contemplated to be operated in the future); to the best of the Company’s knowledge, the Company’s or its Subsidiaries’ current and intended products, services and processes do not infringe on any Intellectual Property or other rights

regarding suspension or cancellation of any of the Company Permits. Neither the Company nor any of its Subsidiaries is in conflict with, or in default or violation of, any of the Company Permits, except for any such conflicts, defaults or violations
which, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. Since December 31, 2005, neither the Company nor any of its Subsidiaries has received any notification with respect to possible
conflicts, defaults or violations of applicable laws, except for notices relating to possible conflicts, defaults or violations, which conflicts, defaults or violations would not have a Material Adverse Effect. 
 s. Environmental Matters. 
 (i) Except as set forth in Schedule 3(s), there are, to the Company’s knowledge, with respect to the Company or any of its Subsidiaries or any predecessor of the Company, no past or present violations of Environmental
Laws (as defined below), releases of any material into the environment, actions, activities, circumstances, conditions, events, incidents, or contractual obligations which may give rise to any common law environmental liability or any liability
under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 or similar federal, state, local or foreign laws and neither the Company nor any of its Subsidiaries has received any notice with respect to any of the foregoing,
nor is any action pending or, to the Company’s knowledge, threatened in connection with any of the foregoing. The term “Environmental Laws” means all federal, state, local or foreign 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. 
 (ii) Other than those that are or were stored, used or disposed of in compliance with
applicable law, no Hazardous Materials are contained on or about any real property currently owned, leased or used by the Company or any of its Subsidiaries, and no Hazardous Materials were released on or about any real property previously owned,
leased or used by the Company or any of its Subsidiaries during the period the property was owned, leased or used by the Company or any of its Subsidiaries, except in the normal course of the Company’s or any of its Subsidiaries’ business.

  

 11 

 (iii) Except as set forth in Schedule 3(s), there are no underground storage tanks on or
under any real property owned, leased or used by the Company or any of its Subsidiaries that are not in compliance with applicable law. 
 t. Title to Property. The Company and its Subsidiaries have good and marketable title in fee simple to all real property and good and marketable title to all personal property owned by them which is material to the business of
the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as are described in Schedule 3(t) or such as would not have a Material Adverse Effect. Any real property and facilities held
under lease by the Company and its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as would not have a Material Adverse Effect. 
 u. Insurance. Except as set forth in Schedule 3(u), the Company and each of its Subsidiaries are insured by insurers of recognized
financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are engaged. Neither the Company nor any such
Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage 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
would not have a Material Adverse Effect. The Company has provided to Buyer true and correct copies of all policies relating to directors’ and officers’ liability coverage, errors and omissions coverage, and commercial general liability
coverage. 
 v. Internal Accounting Controls. The Company and each of its Subsidiaries maintain a system of internal
accounting controls sufficient, in the judgment of the Company’s board of directors, 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 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 differences.

 w. Foreign Corrupt Practices. Neither the Company, nor any of its Subsidiaries, nor any director, officer, agent, employee
or other person acting on behalf of the Company or any Subsidiary has, in the course of his actions for, or on behalf of, the Company, used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to
political activity; made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as
amended, or made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee. 
 x. Solvency. Except as provided on Schedule 3(x), the Company (after giving effect to the transactions contemplated by this Agreement) is solvent (i.e., its assets have a fair market value
in excess of the amount required to pay its probable liabilities on its 

  

 12 

 
existing debts as they become absolute and matured) and currently the Company has no information that would lead it to reasonably conclude that the Company
would not, after giving effect to the transaction contemplated by this Agreement, have the ability to, nor does it intend to take any action that would impair its ability to, pay its debts from time to time incurred in connection therewith as such
debts mature. Except as provided on Schedule 3(x), the Company did not receive a qualified opinion from its auditors with respect to its most recent fiscal year end and, after giving effect to the transactions contemplated by this Agreement, does
not anticipate or know of any basis upon which its auditors might issue a qualified opinion in respect of its current fiscal year. 
 y.
No Investment Company. The Company is not, and upon the issuance and sale of the Securities as contemplated by this Agreement will not be an “investment company” required to be registered under the Investment Company Act of 1940
(an “Investment Company”). The Company is not controlled by an Investment Company. 
 z. Breach of Representations
and Warranties by the Company. If the Company breaches any of the representations or warranties set forth in this Section 3, and in addition to any other remedies available to the Buyers pursuant to this Agreement, the Company shall pay
to the Buyer the Standard Liquidated Damages Amount in cash or in shares of Common Stock at the option of the Company, until such breach is cured. If the Company elects to pay the Standard Liquidated Damages Amounts in shares of Common Stock, such
shares shall be issued at the Conversion Price at the time of payment. 
 4. COVENANTS. 
 a. Best Efforts. The parties shall use their best efforts to satisfy timely each of the conditions described in Section 6 and 7 of
this Agreement. 
 b. Form D; Blue Sky Laws. The Company agrees to file a Form D with respect to the Securities as required
under Regulation D and to provide a copy thereof to each Buyer promptly after such filing. The Company shall, on or before the Closing Date, take such action as the Company shall reasonably determine is necessary to qualify the Securities for sale
to the Buyers at the applicable closing 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), and shall provide evidence of any
such action so taken to each Buyer on or prior to the Closing Date. 
 c. Reporting Status; Eligibility to Use Form S-3, SB-2 or Form
S-1. The Company’s Common Stock is registered under Section 12(g) of the 1934 Act. The Company represents and warrants that it meets the requirements for the use of Form S-3 (or if the Company is not eligible for the use of
Form S-3 as of the Filing Date (as defined in the Registration Rights Agreement), the Company may use the form of registration for which it is eligible at that time) for registration of the sale by the Buyer of the Registrable Securities (as defined
in the Registration Rights Agreement). So long as the Buyer beneficially owns any of the Securities, 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 permit 

  

 13 

 
such termination. The Company further agrees to file all reports required to be filed by the Company with the SEC in a timely manner so as to become
eligible, and thereafter to maintain its eligibility, for the use of Form S-3. The Company shall issue a press release describing the material terms of the transaction contemplated hereby as soon as practicable following the Closing Date but in no
event more than two (2) business days of the Closing Date, which press release shall be subject to prior review by the Buyers. The Company agrees that such press release shall not disclose the name of the Buyers unless expressly consented to in
writing by the Buyers or unless required by applicable law or regulation, and then only to the extent of such requirement. 
 d. Use
of Proceeds. The Company shall use the proceeds from the sale of the Debentures and the Warrants in the manner set forth in Schedule 4(d) attached hereto and made a part hereof and shall not, directly or indirectly, use such proceeds
for any loan to or investment in any other corporation, partnership, enterprise or other person (except in connection with its currently existing direct or indirect Subsidiaries) 
 e. Future Offerings. Subject to the exceptions described below, the Company will not, without the prior written consent of a
majority-in-interest of the Buyers, not to be unreasonably withheld, (A) negotiate or contract with any party to obtain additional equity financing (including debt financing with an equity component) that involves the issuance of convertible
securities that are convertible into an indeterminate number of shares of Common Stock or (B) grant any registration rights in connection with any issuance of Common Stock or warrants during the period (the “Lock-up Period”)
beginning on the Closing Date and ending on the later of (i) two hundred seventy (270) days from the Closing Date and (ii) one hundred eighty (180) days from the date the Registration Statement (as defined in the Registration
Rights Agreement) is declared effective (plus any days in which sales cannot be made thereunder). Notwithstanding the foregoing, the Company shall be permitted to obtain additional equity financing (including debt financing with an equity component)
that does not involve the issuance of convertible securities that are convertible into an indeterminate number of shares of Common Stock and which involves the grant of registration rights, so long as such registration rights do not become effective
or may not be invoked by the holder thereof for a period of at least 320 days from the Closing Date. In addition, subject to the exceptions described below, the Company will not conduct any equity financing (including debt with an equity component)
(“Future Offerings”) during the period beginning on the Closing Date and ending two (2) years after the end of the Lock-up Period unless it shall have first delivered to each Buyer, at least twenty (20) business days prior
to the closing of such Future Offering, written notice describing the proposed Future Offering, including the terms and conditions thereof and proposed definitive documentation to be entered into in connection therewith, and providing each Buyer an
option during the fifteen (15) day period following delivery of such notice to purchase its pro rata share (based on the ratio that the aggregate principal amount of Debentures purchased by it hereunder bears to the aggregate principal amount
of Debentures purchased hereunder) of the securities being offered in the Future Offering on the same terms as contemplated by such Future Offering (the limitations referred to in this sentence and the preceding sentence are collectively referred to
as the “Capital Raising Limitations”). In the event the terms and conditions of a proposed Future Offering are amended in any respect after delivery of the notice to the Buyers concerning the proposed Future Offering, the Company
shall deliver a new notice to each Buyer describing the amended terms and conditions of the proposed Future Offering and each Buyer thereafter 

  

 14 

 
shall have an option during the fifteen (15) day period following delivery of such new notice to purchase its pro rata share of the securities being
offered on the same terms as contemplated by such proposed Future Offering, as amended. The foregoing sentence shall apply to successive amendments to the terms and conditions of any proposed Future Offering. The Capital Raising Limitations shall
not apply to any transaction involving (i) issuances of securities in a firm commitment underwritten public offering (excluding a continuous offering pursuant to Rule 415 under the 1933 Act) or (ii) issuances of securities as consideration
for a merger, consolidation or purchase of assets, or in connection with any strategic partnership or joint venture (the primary purpose of which is not to raise equity capital), or in connection with the disposition or acquisition of a business,
product or license by the Company. The Capital Raising Limitations also shall not apply to the issuance of securities upon exercise or conversion of the Company’s options, warrants or other convertible securities outstanding as of the date
hereof or to the grant of additional options or warrants, or the issuance of additional securities, under any Company stock option or restricted stock plan approved by the shareholders of the Company. 
 f. Expenses. At the Closing, the Company shall reimburse Buyers for expenses incurred by them in connection with the negotiation,
preparation, execution, delivery and performance of this Agreement and the other agreements to be executed in connection herewith (“Documents”), including, without limitation, attorneys’ and consultants’ fees and expenses,
transfer agent fees, fees for stock quotation services, fees relating to any amendments or modifications of the Documents or any consents or waivers of provisions in the Documents, fees for the preparation of opinions of counsel, escrow fees, and
costs of restructuring the transactions contemplated by the Documents. When possible, the Company must pay these fees directly, otherwise the Company must make immediate payment for reimbursement to the Buyers for all fees and expenses immediately
upon written notice by the Buyer or the submission of an invoice by the Buyer If the Company fails to reimburse the Buyer in full within three (3) business days of the written notice or submission of invoice by the Buyer, the Company shall pay
interest on the total amount of fees to be reimbursed at a rate of 15% per annum. 
 g. Financial Information. The
Company agrees to send the following reports to each Buyer until such Buyer transfers, assigns, or sells all of the Securities: (i) within ten (10) business days after the filing with the SEC, a copy of its Annual Report on Form 10-KSB its
Quarterly Reports on Form 10-QSB and any Current Reports on Form 8-K; (ii) within one (1) business day after release, copies of all press releases issued by the Company or any of its Subsidiaries; and (iii) contemporaneously with the
making available or giving to the shareholders of the Company, copies of any notices or other information the Company makes available or gives to such shareholders. 
 h. Authorization and Reservation of Shares. Upon the increase in the number of authorized shares of the Company’s Common Stock to 500,000,000 shares within thirty (30) days from the date hereof
and subject to obtaining Stockholder Approval (as defined in Section 4(k)), the Company shall at all times have authorized, and reserved for the purpose of issuance, a sufficient number of shares of Common Stock to provide for the full
conversion or exercise of the outstanding Debentures and Warrants and issuance of the Conversion Shares and Warrant Shares in connection therewith (based on the Conversion Price of the Debentures or Exercise Price of the Warrants in effect from time
to time) and as otherwise required by the 

  

 15 

 
Debentures. The Company shall not reduce the number of shares of Common Stock reserved for issuance upon conversion of Debentures and exercise of the
Warrants without the consent of each Buyer. The Company shall at all times maintain the number of shares of Common Stock so reserved for issuance at an amount (“Reserved Amount”) equal to no less than two (2) times the number
that is then actually issuable upon full conversion of the Debentures and Additional Debentures and upon exercise of the Warrants and the Additional Warrants (based on the Conversion Price of the Debentures or the Exercise Price of the Warrants in
effect from time to time). If at any time the number of shares of Common Stock authorized and reserved for issuance (“Authorized and Reserved Shares”) is below the Reserved Amount, the Company will promptly take all corporate action
necessary to authorize and reserve a sufficient number of shares, including, without limitation, calling a special meeting of shareholders to authorize additional shares to meet the Company’s obligations under this Section 4(h), in the
case of an insufficient number of authorized shares, obtain shareholder approval of an increase in such authorized number of shares, and voting the management shares of the Company in favor of an increase in the authorized shares of the Company to
ensure that the number of authorized shares is sufficient to meet the Reserved Amount. If the Company fails to obtain such shareholder approval within thirty (30) days following the date on which the number of Reserved Amount exceeds the
Authorized and Reserved Shares, the Company shall pay to the Borrower the Standard Liquidated Damages Amount, in cash or in shares of Common Stock at the option of the Buyer. If the Buyer elects to be paid the Standard Liquidated Damages Amount in
shares of Common Stock, such shares shall be issued at the Conversion Price at the time of payment. In order to ensure that the Company has authorized a sufficient amount of shares to meet the Reserved Amount at all times, the Company must deliver
to the Buyer at the end of every month a list detailing (1) the current amount of shares authorized by the Company and reserved for the Buyer; and (2) amount of shares issuable upon conversion of the Debentures and upon exercise of the
Warrants and as payment of interest accrued on the Debentures for one year. If the Company fails to provide such list within five (5) business days of the end of each month, the Company shall pay the Standard Liquidated Damages Amount, in cash
or in shares of Common Stock at the option of the Buyer, until the list is delivered. If the Buyer elects to be paid the Standard Liquidated Damages Amount in shares of Common Stock, such shares shall be issued at the Conversion Price at the time of
payment. 
 i. Listing. The Company shall promptly secure the listing of the Conversion Shares and Warrant Shares upon each
national securities exchange or automated quotation system, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance) and, so long as any Buyer owns any of the Securities, shall maintain, so long as any other
shares of Common Stock shall be so listed, such listing of all Conversion Shares and Warrant Shares from time to time issuable upon conversion of the Debentures or exercise of the Warrants. The Company will obtain and, so long as any Buyer owns any
of the Securities, maintain the listing and trading of its Common Stock on the OTCBB or any equivalent replacement exchange, the Nasdaq National Market (“Nasdaq”), the Nasdaq SmallCap Market (“Nasdaq SmallCap”), the
New York Stock Exchange (“NYSE”), or the American Stock Exchange (“AMEX”) and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the National
Association of Securities Dealers (“NASD”) and such exchanges, as applicable. The Company shall promptly provide to each Buyer copies of any notices it receives from the OTCBB and any other exchanges or quotation systems on which
the Common Stock is then listed regarding the continued eligibility of the Common Stock for listing on such exchanges and quotation systems. 
  

 16 

 j. Corporate Existence. So long as a Buyer beneficially owns any Debentures or Warrants,
the Company shall maintain its corporate existence and shall not sell all or substantially all of the Company’s assets, except in the event of a merger or consolidation or sale of all or substantially all of the Company’s assets, where the
surviving or successor entity in such transaction (i) assumes the Company’s obligations hereunder and under the agreements and instruments entered into in connection herewith and (ii) is a publicly traded corporation whose Common
Stock is listed for trading on the OTCBB, Nasdaq, Nasdaq SmallCap, NYSE or AMEX. 
 k. No Integration. The Company shall not
make any offers or sales of any security (other than the Securities) under circumstances that would require registration of the Securities being offered or sold hereunder under the 1933 Act or cause the offering of the Securities to be integrated
with any other offering of securities by the Company for the purpose of any stockholder approval provision applicable to the Company or its securities. 
 l. Subsequent Investment. The Company and the Buyers agree that, upon the filing by the Company of the Registration Statement to be filed pursuant to the Registration Rights Agreement (the
“Filing Date”), the Buyers shall purchase additional Notes (the “Filing Notes”) in the aggregate principal amount of Six Hundred Thousand Dollars ($600,000) for an aggregate purchase price of Six Hundred Thousand
Dollars ($600,000), with the closing of such purchase to occur on the Filing Date; provided, however, that the obligation of each Buyer to purchase the Filing Notes and the Filing Warrants is subject to the satisfaction, at or before
the closing of such purchase and sale, of the conditions set forth in Section 7. The Company and the Buyers further agree that, upon the declaration of effectiveness of the Registration Statement to be filed pursuant to the Registration Rights
Agreement (the “Effective Date”), the Buyers shall purchase additional notes (the “Effectiveness Notes” and, collectively with the Filing Notes, the “Additional Notes”) in the aggregate principal
amount of Seven Hundred Thousand Dollars ($700,000) for an aggregate purchase price of Seven Hundred Thousand Dollars ($700,000), with the closing of such purchase to occur on the Effective Date; provided, however, that the obligation
of each Buyer to purchase the Additional Notes is subject to the satisfaction, at or before the closing of such purchase and sale, of the conditions set forth in Section 7; and, provided, further, that there shall not have been a
Material Adverse Effect as of such effective date. The terms of the Additional Notes shall be identical to the terms of the Notes to be issued on the Closing Date. The Common Stock underlying the Additional Notes shall be Registrable Securities (as
defined in the Registration Rights Agreement) and shall be included in the Registration Statement to be filed pursuant to the Registration Rights Agreement. 
 m. Key Man Insurance. The Company shall use its best efforts to obtain, on or before five (5) business days from the date hereof, key man life insurance on all key executive employees.

 n. Restriction on Short Sales. The Buyers agree that, so long as any of the Notes remain outstanding, but in no event less
than two (2) years from the date hereof, the Buyers will not enter into or effect any “short sales” (as such term is defined in Rule 3b-3 of the 1934 Act) of the Common Stock or hedging transaction which establishes a net short
position with respect to the Common Stock. 
  

 17 

 o. Breach of Covenants. If the Company breaches any of the covenants set forth in this
Section 4, and in addition to any other remedies available to the Buyers pursuant to this Agreement, the Company shall pay to the Buyers the Standard Liquidated Damages Amount, in cash or in shares of Common Stock at the option of the Company,
until such breach is cured. If the Company elects to pay the Standard Liquidated Damages Amount in shares, such shares shall be issued at the Conversion Price at the time of payment. 
 5. TRANSFER AGENT INSTRUCTIONS. The Company shall issue irrevocable instructions to its transfer agent to issue certificates, registered in
the name of each Buyer or its nominee, for the Conversion Shares and Warrant Shares in such amounts as specified from time to time by each Buyer to the Company upon conversion of the Debentures or exercise of the Warrants in accordance with the
terms thereof (the “Irrevocable Transfer Agent Instructions”). Prior to registration of the Conversion Shares and Warrant Shares under the 1933 Act or the date on which the Conversion Shares and Warrant Shares may be sold pursuant
to Rule 144 without any restriction as to the number of Securities as of a particular date that can then be immediately sold, all such certificates shall bear the restrictive legend specified in Section 2(g) of this Agreement. The Company
warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5, and stop transfer instructions to give effect to Section 2(f) hereof (in the case of the Conversion Shares and Warrant
Shares, prior to registration of the Conversion Shares and Warrant Shares under the 1933 Act or the date on which the Conversion Shares and Warrant Shares may be sold pursuant to Rule 144 without any restriction as to the number of Securities as of
a particular date that can then be immediately sold), will be given by the Company to its transfer agent and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this
Agreement and the Registration Rights Agreement. Nothing in this Section shall affect in any way the Buyer’s obligations and agreement set forth in Section 2(g) hereof to comply with all applicable prospectus delivery requirements, if any,
upon re-sale of the Securities. If a Buyer provides the Company with (i) an opinion of counsel in form, substance and scope customary for opinions in comparable transactions, to the effect that a public sale or transfer of such Securities may
be made without registration under the 1933 Act and such sale or transfer is effected or (ii) the Buyer provides reasonable assurances that the Securities can be sold pursuant to Rule 144, the Company shall permit the transfer, and, in the case
of the Conversion Shares and Warrant Shares, promptly instruct its transfer agent to issue one or more certificates, free from restrictive legend, in such name and in such denominations as specified by such Buyer. The Company acknowledges that a
breach by it of its obligations hereunder will cause irreparable harm to the Buyers, by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations under this Section 5 may be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section, that the Buyers shall be entitled, in addition to all other available remedies, to an
injunction restraining any breach and requiring immediate transfer, without the necessity of showing economic loss and without any bond or other security being required. 
  

 18

required by this Agreement to be performed, satisfied or complied with by the Company at or prior to the Closing Date. The Buyer shall have received

	Baltimore, Maryland	  			
	July 31, 2006	  	$	[            	]

 FOR VALUE RECEIVED, UNIVEC, INC., a Delaware corporation (hereinafter called the
“Borrower”), hereby promises to pay to the order of [        ] or registered assigns (the “Holder”) the sum of
$[            ], on July 31, 2009 (the “Maturity Date”), and to pay interest on the unpaid principal balance hereof at the rate of six percent (6%) (the
“Interest Rate”) per annum from July 31, 2006 (the “Issue Date”) until the same becomes due and payable, whether at maturity or upon acceleration or by prepayment or otherwise. Any amount of principal or
interest on this Note which is not paid when due shall bear interest at the rate of fifteen percent (15%) per annum from the due date thereof until the same is paid (“Default Interest”). Interest shall commence accruing on the
Issue Date, shall be computed on the basis of a 365-day year and the actual number of days elapsed and shall be payable quarterly provided that no interest shall be due and payable for any month in which the Trading Price (as such term is defined
below) is greater than $.01 for each Trading Day (as such term is defined below) of the month. All payments due hereunder (to the extent not converted into common stock, $.01 par value per share (the “Common Stock”) in accordance
with the terms hereof) shall be made in lawful money of the United States of America. All payments shall be made at such address as the Holder shall hereafter give to the Borrower by written notice made in accordance with the provisions of this
Note. Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a business day, the same shall instead be due on the next succeeding day which is a business day and, in the case of any interest payment date
which is not the date on which this Note is paid in full, the extension of the due date thereof shall not be taken into account for purposes of determining the amount of interest due on such date. As used in this Note, the term “business
day” shall mean any day other than a Saturday, Sunday or a day on which commercial banks in the city of New York, New York (and Baltimore, Maryland) are authorized or required by law or executive order to remain closed. Each capitalized term
used 

 
herein, and not otherwise defined, shall have the meaning ascribed thereto in that certain Securities Purchase Agreement, dated July 31, 2006, pursuant
to which this Note was originally issued (the “Purchase Agreement”). 
 This Note is free from all taxes, liens, claims and
encumbrances with respect to the issue thereof and shall not be subject to preemptive rights or other similar rights of shareholders of the Borrower and will not impose personal liability upon the holder thereof. The obligations of the Borrower
under this Note shall be secured by that certain Security Agreement and Intellectual Property Security Agreement, each dated July 31, 2006 by and between the Borrower and the Holder. 
 The following terms shall apply to this Note: 
 ARTICLE I. CONVERSION RIGHTS 
 1.1 Conversion Right. The Holder shall have the right from time to time, and at
any time on or prior to the earlier of (i) the Maturity Date and (ii) the date of payment of the Default Amount (as defined in Article III) pursuant to Section 1.6(a) or Article III, the Optional Prepayment Amount (as defined in
Section 5.1 or any payments pursuant to Section 1.7, each in respect of the remaining outstanding principal amount of this Note to convert all or any part of the outstanding and unpaid principal amount of this Note into fully paid and
non-assessable shares of Common Stock, as such Common Stock exists on the Issue Date, or any shares of capital stock or other securities of the Borrower into which such Common Stock shall hereafter be changed or reclassified at the conversion price
(the “Conversion Price”) determined as provided herein (a “Conversion”); provided, however, that in no event shall the Holder be entitled to convert any portion of this Note in excess of that portion
of this Note upon conversion of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the
unconverted portion of the Notes or the unexercised or unconverted portion of any other security of the Borrower (including, without limitation, the warrants issued by the Borrower pursuant to the Purchase Agreement) subject to a limitation on
conversion or exercise analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the conversion of the portion of this Note with respect to which the determination of this proviso is being made,
would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock and provided further that the Holder shall not be entitled to convert any portion of this Note during
any month immediately succeeding a Determination Date on which the Borrower exercises its prepayment option pursuant to Section 5.2 of this Note. For purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be
determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such proviso. The number of shares of Common Stock to be issued
upon each conversion of this Note shall be determined by dividing the Conversion Amount (as defined below) by the applicable Conversion Price then in effect on the date specified in the notice of conversion, in the form attached hereto as Exhibit A
(the “Notice of Conversion”), delivered to the Borrower by the Holder in accordance with Section 1.4 below; provided that the Notice of Conversion is submitted by facsimile (or by other means 

  

 2 

 
resulting in, or reasonably expected to result in, notice) to the Borrower before 6:00 p.m., New York, New York time on such conversion date (the
“Conversion Date”). The term “Conversion Amount” means, with respect to any conversion of this Note, the sum of (1) the principal amount of this Note to be converted in such conversion plus
(2) accrued and unpaid interest, if any, on such principal amount at the interest rates provided in this Note to the Conversion Date, provided, however, that the Company shall have the right to pay any or all interest in cash plus
(3) Default Interest, if any, on the amounts referred to in the immediately preceding clauses (1) and/or (2) plus (4) at the Holder’s option, any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof
or pursuant to Section 2(c) of that certain Registration Rights Agreement, dated as of July 31, 2006, executed in connection with the initial issuance of this Note and the other Notes issued on the Issue Date (the “Registration
Rights Agreement”). The term “Determination Date” means the last business day of each month after the Issue Date. 
 1.2 Conversion Price. 
 (a) Calculation of Conversion Price. The Conversion Price shall be the Variable
Conversion Price (as defined herein) (subject, in each case, to equitable adjustments for stock splits, stock dividends or rights offerings by the Borrower relating to the Borrower’s securities or the securities of any subsidiary of the
Borrower, combinations, recapitalization, reclassifications, extraordinary distributions and similar events). The “Variable Conversion Price” shall mean the Applicable Percentage (as defined herein) multiplied by the Market Price
(as defined herein). “Market Price” means the average of the lowest three (3) Trading Prices (as defined below) for the Common Stock during the twenty (20) Trading Day period ending one Trading Day prior to the date the
Conversion Notice is sent by the Holder to the Borrower via facsimile (the “Conversion Date”). “Trading Price” means, for any security as of any date, the intraday trading price on the Over-the-Counter Bulletin
Board (the “OTCBB”) as reported by a reliable reporting service (“Reporting Service”) mutually acceptable to Borrower and Holder and hereafter designated by Holders of a majority in interest of the Notes and the
Borrower or, if the OTCBB is not the principal trading market for such security, the intraday trading price of such security on the principal securities exchange or trading market where such security is listed or traded or, if no intraday trading
price of such security is available in any of the foregoing manners, the average of the intraday trading prices of any market makers for such security that are listed in the “pink sheets” by the National Quotation Bureau, Inc. If the
Trading Price cannot be calculated for such security on such date in the manner provided above, the Trading Price shall be the fair market value as mutually determined by the Borrower and the holders of a majority in interest of the Notes being
converted for which the calculation of the Trading Price is required in order to determine the Conversion Price of such Notes. “Trading Day” shall mean any day on which the Common Stock is traded for any period on the OTCBB, or on
the principal securities exchange or other securities market on which the Common Stock is then being traded. “Applicable Percentage” shall mean 50%; provided, however, that the Applicable Percentage shall be increased to
(i) 55% in the event that the Registration Statement (as defined in the Registration Rights Agreement) is filed on or before the Filing Date (as defined in the in the Registration Rights Agreement) and (ii) 60% in the event that the
Registration Statement (as defined in the Registration Rights Agreement) becomes effective on or before the Effectiveness Deadline (as defined in the Registration Rights Agreement). In addition, the Holder agrees that it will limit all of its
conversions to no more than the greater of (1) $80,000 per calendar month; or (2) the average daily dollar volume calculated during the ten (10) business days prior to a conversion, per conversion. 
  

 3 

 (b) Conversion Price During Major Announcements. Notwithstanding anything contained in
Section 1.2(a) to the contrary, in the event the Borrower (i) makes a public announcement that it intends to consolidate or merge with any other corporation (other than a merger in which the Borrower is the surviving or continuing
corporation and its capital stock is unchanged) or sell or transfer all or substantially all of the assets of the Borrower or (ii) any person, group or entity (including the Borrower) publicly announces a tender offer to purchase 50% or more of
the Borrower’s Common Stock (or any other takeover scheme) (the date of the announcement referred to in clause (i) or (ii) is hereinafter referred to as the “Announcement Date”), then the Conversion Price shall,
effective upon the Announcement Date and continuing through the Adjusted Conversion Price Termination Date (as defined below), be equal to the lower of (x) the Conversion Price which would have been applicable for a Conversion occurring on the
Announcement Date and (y) the Conversion Price that would otherwise be in effect. From and after the Adjusted Conversion Price Termination Date, the Conversion Price shall be determined as set forth in this Section 1.2(a). For purposes
hereof, “Adjusted Conversion Price Termination Date” shall mean, with respect to any proposed transaction or tender offer (or takeover scheme) for which a public announcement as contemplated by this Section 1.2(b) has been
made, the date upon which the Borrower (in the case of clause (i) above) or the person, group or entity (in the case of clause (ii) above) consummates or publicly announces the termination or abandonment of the proposed transaction or
tender offer (or takeover scheme) which caused this Section 1.2(b) to become operative. 
 1.3 Authorized Shares. Subject
to Stockholder Approval (as such term is defined in Section 4(n) of the Securities Purchase Agreement), the Borrower covenants that upon the increase in the number of authorized shares of the Company’s Common Stock to 500,000,000 shares
within thirty (30) days from the date hereof and during the period the conversion right exists, the Borrower will reserve from its authorized and unissued Common Stock a sufficient number of shares, free from preemptive rights thereafter, to
provide for the issuance of Common Stock upon the full conversion of this Note and the other Notes issued pursuant to the Purchase Agreement. The Borrower is required at all times to have authorized and reserved two times the number of shares that
is actually issuable upon full conversion of the Notes (based on the Conversion Price of the Notes or the Exercise Price of the Warrants in effect from time to time) (the “Reserved Amount”). The Reserved Amount shall be increased
from time to time in accordance with the Borrower’s obligations pursuant to Section 4(h) of the Purchase Agreement. The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. In
addition, if the Borrower shall issue any securities or make any change to its capital structure which would change the number of shares of Common Stock into which the Notes shall be convertible at the then current Conversion Price, the Borrower
shall at the same time make proper provision so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights, for conversion of the outstanding Notes. The Borrower
(i) acknowledges that it has irrevocably instructed its transfer agent to issue certificates for the Common Stock issuable upon conversion of this Note, and (ii) agrees that its issuance of this Note shall constitute full authority to its
officers and agents who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for shares of Common Stock in accordance with the terms and conditions of this Note. 
  

 4 

 If, at any time a Holder of this Note submits a Notice of Conversion, and the Borrower does not have
sufficient authorized but unissued shares of Common Stock available to effect such conversion in accordance with the provisions of this Article I (a “Conversion Default”), subject to Section 4.8, the Borrower shall issue to the
Holder all of the shares of Common Stock which are then available to effect such conversion. The portion of this Note which the Holder included in its Conversion Notice and which exceeds the amount which is then convertible into available shares of
Common Stock (the “Excess Amount”) shall, notwithstanding anything to the contrary contained herein, not be convertible into Common Stock in accordance with the terms hereof until (and at the Holder’s option at any time after)
the date additional shares of Common Stock are authorized by the Borrower to permit such conversion, at which time the Conversion Price in respect thereof shall be the lesser of (i) the Conversion Price on the Conversion Default Date (as
defined below) and (ii) the Conversion Price on the Conversion Date thereafter elected by the Holder in respect thereof. In addition, the Borrower shall pay to the Holder payments (“Conversion Default Payments”) for a
Conversion Default in the amount of (x) the sum of (1) the then outstanding principal amount of this Note plus (2) accrued and unpaid interest on the unpaid principal amount of this Note through the Authorization Date
(as defined below) plus (3) Default Interest, if any, on the amounts referred to in clauses (1) and/or (2), multiplied by (y) .24, multiplied by (z) (N/365), where N = the number of days from the day the
holder submits a Notice of Conversion giving rise to a Conversion Default (the “Conversion Default Date”) to the date (the “Authorization Date”) that the Borrower authorizes a sufficient number of shares of Common
Stock to effect conversion of the full outstanding principal balance of this Note. The Borrower shall use its best efforts to authorize a sufficient number of shares of Common Stock as soon as practicable following the earlier of (i) such time
that the Holder notifies the Borrower or that the Borrower otherwise becomes aware that there are or likely will be insufficient authorized and unissued shares to allow full conversion thereof and (ii) a Conversion Default. The Borrower shall
send notice to the Holder of the authorization of additional shares of Common Stock, the Authorization Date and the amount of Holder’s accrued Conversion Default Payments. The accrued Conversion Default Payments for each calendar month shall be
paid in cash or shall be convertible into Common Stock (at such time as there are sufficient authorized shares of Common Stock) at the applicable Conversion Price, at the Borrower’s option, as follows: 
 (a) In the event Holder elects to take such payment in cash, cash payment shall be made to Holder by the fifth (5th) day of the month following the month in which it has accrued; and 
 (b) In the event Holder elects to take such payment in Common Stock, the Holder may convert such payment amount into Common Stock at the
Conversion Price (as in effect at the time of conversion) at any time after the fifth day of the month following the month in which it has accrued in accordance with the terms of this Article I (so long as there is then a sufficient number of
authorized shares of Common Stock). 
 The Holder’s election shall be made in writing to the Borrower at any time prior to 6:00 p.m.,
New York, New York time, on the third day of the month following the month in 

  

 5 

 
which Conversion Default payments have accrued. If no election is made, the Holder shall be deemed to have elected to receive cash. Nothing herein shall
limit the Holder’s right to pursue actual damages (to the extent in excess of the Conversion Default Payments) for the Borrower’s failure to maintain a sufficient number of authorized shares of Common Stock, and each holder shall have the
right to pursue all remedies available at law or in equity (including degree of specific performance and/or injunctive relief). 
 1.4
Method of Conversion. 
 (a) Mechanics of Conversion. Subject to Section 1.1, this Note may be converted by the
Holder in whole or in part at any time from time to time after the Issue Date, by (A) submitting to the Borrower a Notice of Conversion (by facsimile or other reasonable means of communication dispatched on the Conversion Date prior to 6:00
p.m., New York, New York time) and (B) subject to Section 1.4(b), surrendering this Note at the principal office of the Borrower. 
 (b) Surrender of Note Upon Conversion. Notwithstanding anything to the contrary set forth herein, upon conversion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this
Note to the Borrower unless the entire unpaid principal amount of this Note is so converted. The Holder and the Borrower shall maintain records showing the principal amount so converted and the dates of such conversions or shall use such other
method, reasonably satisfactory to the Holder and the Borrower, so as not to require physical surrender of this Note upon each such conversion. In the event of any dispute or discrepancy, such records of the Borrower shall be controlling and
determinative in the absence of manifest error. Notwithstanding the foregoing, if any portion of this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this Note to the Borrower,
whereupon the Borrower will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the aggregate the
remaining unpaid principal amount of this Note. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and
unconverted principal amount of this Note represented by this Note may be less than the amount stated on the face hereof. 
 (c)
Payment of Taxes. The Borrower shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock or other securities or property on conversion of this Note in
a name other than that of the Holder (or in street name), and the Borrower shall not be required to issue or deliver any such shares or other securities or property unless and until the person or persons (other than the Holder or the custodian in
whose street name such shares are to be held for the Holder’s account) requesting the issuance thereof shall have paid to the Borrower the amount of any such tax or shall have established to the satisfaction of the Borrower that such tax has
been paid. 
 (d) Delivery of Common Stock Upon Conversion. Upon receipt by the Borrower from the Holder of a facsimile
transmission (or other reasonable means of communication) of a Notice of Conversion meeting the requirements for conversion as provided 

  

 6 

 
in this Section 1.4, the Borrower shall issue and deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the
Common Stock issuable upon such conversion within three (3) business days after such receipt (and, solely in the case of conversion of the entire unpaid principal amount hereof, surrender of this Note) (such third business day being hereinafter
referred to as the “Deadline”) in accordance with the terms hereof and the Purchase Agreement (including, without limitation, in accordance with the requirements of Section 2(g) of the Purchase Agreement that certificates for
shares of Common Stock issued on or after the effective date of the Registration Statement upon conversion of this Note shall not bear any restrictive legend). 
 (e) Obligation of Borrower to Deliver Common Stock. Upon receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed to be the holder of record of the Common Stock issuable upon such
conversion, the outstanding principal amount and the amount of accrued and unpaid interest on this Note shall be reduced to reflect such conversion, and, unless the Borrower defaults on its obligations under this Article I, all rights with respect
to the portion of this Note being so converted shall forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets, as herein provided, on such conversion. If the Holder shall have given a Notice of
Conversion as provided herein, the Borrower’s obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional, irrespective of the absence of any action by the Holder to enforce the same, any waiver or
consent with respect to any provision thereof, the recovery of any judgment against any person or any action to enforce the same, any failure or delay in the enforcement of any other obligation of the Borrower to the holder of record, or any setoff,
counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder of any obligation to the Borrower, and irrespective of any other circumstance which might otherwise limit such obligation of the Borrower to the
Holder in connection with such conversion. The Conversion Date specified in the Notice of Conversion shall be the Conversion Date so long as the Notice of Conversion is received by the Borrower before 6:00 p.m., New York, New York time, on such
date. 
 (f) Delivery of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing the
Common Stock issuable upon conversion, provided the Borrower’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon request of the
Holder and its compliance with the provisions contained in Section 1.1 and in this Section 1.4, the Borrower shall use its best efforts to cause its transfer agent to electronically transmit the Common Stock issuable upon conversion to the
Holder by crediting the account of Holder’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission (“DWAC”) system. 
 (g) Failure to Deliver Common Stock Prior to Deadline. Without in any way limiting the Holder’s right to pursue other remedies, including actual damages and/or equitable relief, the parties agree
that if delivery of the Common Stock issuable upon conversion of this Note is more than two (2) business days after the Deadline (other than a failure due to the circumstances described in Section 1.3 above, which failure shall be governed
by such Section) the Borrower shall pay to the Holder $2,000 per day in cash, for each day beyond the Deadline that the Borrower fails to deliver such Common Stock. Such cash amount shall be paid to Holder by the fifth day of the month following the
month in which it has accrued or, at the option 

  

 7 

 
of the Holder (by written notice to the Borrower by the first day of the month following the month in which it has accrued), shall be added to the principal
amount of this Note, in which event interest shall accrue thereon in accordance with the terms of this Note and such additional principal amount shall be convertible into Common Stock in accordance with the terms of this Note. 
 1.5 Concerning the Shares. The shares of Common Stock issuable upon conversion of this Note may not be sold or transferred unless
(i) such shares are sold pursuant to an effective registration statement under the Act or (ii) the Borrower or its transfer agent shall have been furnished with an opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions) to the effect that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (iii) such shares are sold or transferred
pursuant to Rule 144 under the Act (or a successor rule) (“Rule 144”) or (iv) such shares are transferred to an “affiliate” (as defined in Rule 144) of the Borrower who agrees to sell or otherwise transfer the shares
only in accordance with this Section 1.5 and who is an Accredited Investor (as defined in the Purchase Agreement). Except as otherwise provided in the Purchase Agreement (and subject to the removal provisions set forth below), until such time
as the shares of Common Stock issuable upon conversion of this Note have been registered under the Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of
securities as of a particular date that can then be immediately sold, each certificate for shares of Common Stock issuable upon conversion of this Note that has not been so included in an effective registration statement or that has not been sold
pursuant to an effective registration statement or an exemption that permits removal of the legend, shall bear a legend substantially in the following form, as appropriate: 
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES MAY NOT BE
SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND SCOPE CUSTOMARY FOR OPINIONS OF COUNSEL IN COMPARABLE TRANSACTIONS, THAT
REGISTRATION IS NOT REQUIRED UNDER SAID ACT UNLESS SOLD PURSUANT TO RULE 144 OR REGULATION S UNDER SAID ACT.” 
 The legend set forth
above shall be removed and the Borrower shall issue to the Holder a new certificate therefor free of any transfer legend if (i) the Borrower or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary
for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made without registration under the Act and the shares are so sold or transferred, (ii) such Holder provides the
Borrower or its transfer agent with reasonable assurances that the Common Stock issuable upon conversion of this Note (to the extent such securities are deemed to have been acquired on the same date) can be sold pursuant to Rule 144 or (iii) in
the case of the Common Stock issuable upon conversion of this Note, such security is registered for sale by the Holder under an effective registration statement filed under the Act or otherwise may be sold pursuant to Rule 144 without any
restriction as to the number of securities 

  

 8 

 
as of a particular date that can then be immediately sold. Nothing in this Note shall (i) limit the Borrower’s obligation under the Registration
Rights Agreement or (ii) affect in any way the Holder’s obligations to comply with applicable prospectus delivery requirements upon the resale of the securities referred to herein. 
 1.6 Effect of Certain Events. 
 (a) Effect of Merger, Consolidation, Etc. At the option of the Holder, the sale, conveyance or disposition of all or substantially all of the assets of the Borrower, the effectuation by the Borrower of a transaction or series
of related transactions in which more than 50% of the voting power of the Borrower is disposed of, or the consolidation, merger or other business combination of the Borrower with or into any other Person (as defined below) or Persons when the
Borrower is not the survivor shall either: (i) be deemed to be an Event of Default (as defined in Article III) pursuant to which the Borrower shall be required to pay to the Holder upon the consummation of and as a condition to such transaction
an amount equal to the Default Amount (as defined in Article III) or (ii) be treated pursuant to Section 1.6(b) hereof. “Person” shall mean any individual, corporation, limited liability company, partnership, association,
trust or other entity or organization. 
 (b) Adjustment Due to Merger, Consolidation, Etc. If, at any time when this Note is
issued and outstanding and prior to conversion of all of the Notes, there shall be any merger, consolidation, exchange of shares, recapitalization, reorganization, or other similar event, as a result of which shares of Common Stock of the Borrower
shall be changed into the same or a different number of shares of another class or classes of stock or securities of the Borrower or another entity, or in case of any sale or conveyance of all or substantially all of the assets of the Borrower other
than in connection with a plan of complete liquidation of the Borrower, then the Holder of this Note shall thereafter have the right to receive upon conversion of this Note, upon the basis and upon the terms and conditions specified herein and in
lieu of the shares of Common Stock immediately theretofore issuable upon conversion, such stock, securities or assets which the Holder would have been entitled to receive in such transaction had this Note been converted in full immediately prior to
such transaction (without regard to any limitations on conversion set forth herein), and in any such case appropriate provisions shall be made with respect to the rights and interests of the Holder of this Note to the end that the provisions hereof
(including, without limitation, provisions for adjustment of the Conversion Price and of the number of shares issuable upon conversion of the Note) shall thereafter be applicable, as nearly as may be practicable in relation to any securities or
assets thereafter deliverable upon the conversion hereof. The Borrower shall not effect any transaction described in this Section 1.6(b) unless (a) it first gives, to the extent practicable, thirty (30) days prior written notice (but
in any event at least fifteen (15) days prior written notice) of the record date of the special meeting of shareholders to approve, or if there is no such record date, the consummation of, such merger, consolidation, exchange of shares,
recapitalization, reorganization or other similar event or sale of assets (during which time the Holder shall be entitled to convert this Note) and (b) the resulting successor or acquiring entity (if not the Borrower) assumes by written
instrument the obligations of this Section 1.6(b). The above provisions shall similarly apply to successive consolidations, mergers, sales, transfers or share exchanges. 
  

 9 

 (c) Adjustment Due to Distribution. If the Borrower shall declare or make any distribution
of its assets (or rights to acquire its assets) to holders of Common Stock as a dividend, stock repurchase, by way of return of capital or otherwise (including any dividend or distribution to the Borrower’s shareholders in cash or shares (or
rights to acquire shares) of capital stock of a subsidiary (i.e., a spin-off)) (a “Distribution”), then the Holder of this Note shall be entitled, upon any conversion of this Note after the date of record for determining
shareholders entitled to such Distribution, to receive the amount of such assets which would have been payable to the Holder with respect to the shares of Common Stock issuable upon such conversion had such Holder been the holder of such shares of
Common Stock on the record date for the determination of shareholders entitled to such Distribution. 
 (d) Adjustment Due to Dilutive
Issuance. If, at any time when any Notes are issued and outstanding, the Borrower issues or sells, or in accordance with this Section 1.6(d) hereof is deemed to have issued or sold, any shares of Common Stock for no consideration or for
a consideration per share (before deduction of reasonable expenses or commissions or underwriting discounts or allowances in connection therewith) less than the Fixed Conversion Price in effect on the date of such issuance (or deemed issuance) of
such shares of Common Stock (a “Dilutive Issuance”), then immediately upon the Dilutive Issuance, the Variable Conversion Price will be reduced to the amount of the consideration per share received by the Borrower in such Dilutive
Issuance; provided that only one adjustment will be made for each Dilutive Issuance. 
 The Borrower shall be deemed to have issued
or sold shares of Common Stock if the Borrower in any manner issues or grants any warrants, rights or options (not including employee stock option plans), whether or not immediately exercisable, to subscribe for or to purchase Common Stock or other
securities convertible into or exchangeable for Common Stock (“Convertible Securities”) (such warrants, rights and options to purchase Common Stock or Convertible Securities are hereinafter referred to as “Options”)
and the price per share for which Common Stock is issuable upon the exercise of such Options is less than the Variable Conversion Price then in effect, then the Variable Conversion Price shall be equal to such price per share. For purposes of the
preceding sentence, the “price per share for which Common Stock is issuable upon the exercise of such Options” is determined by dividing (i) the total amount, if any, received or receivable by the Borrower as consideration for the
issuance or granting of all such Options, plus the minimum aggregate amount of additional consideration, if any, payable to the Borrower upon the exercise of all such Options, plus, in the case of Convertible Securities issuable upon the exercise of
such Options, the minimum aggregate amount of additional consideration payable upon the conversion or exchange thereof at the time such Convertible Securities first become convertible or exchangeable, by (ii) the maximum total number of shares
of Common Stock issuable upon the exercise of all such Options (assuming full conversion of Convertible Securities, if applicable). No further adjustment to the Conversion Price will be made upon the actual issuance of such Common Stock upon the
exercise of such Options or upon the conversion or exchange of Convertible Securities issuable upon exercise of such Options. 
 Additionally, the Borrower shall be deemed to have issued or sold shares of Common Stock if the Borrower in any manner issues or sells any Convertible Securities, whether or not immediately convertible (other than where the same are
issuable upon the exercise of Options), and the price per share for which Common Stock is issuable upon such 

  

 10 

 
conversion or exchange is less than the Variable Conversion Price then in effect, then the Variable Conversion Price shall be equal to such price per share.
For the purposes of the preceding sentence, the “price per share for which Common Stock is issuable upon such conversion or exchange” is determined by dividing (i) the total amount, if any, received or receivable by the Borrower as
consideration for the issuance or sale of all such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Borrower upon the conversion or exchange thereof at the time such Convertible Securities
first become convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities. No further adjustment to the Variable Conversion Price will be
made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities. 
 (e) Purchase
Rights. If, at any time when any Notes are issued and outstanding, the Borrower issues any convertible securities or rights to purchase stock, warrants, securities or other property (the “Purchase Rights”) pro rata to the
record holders of any class of Common Stock, then the Holder of this Note will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had held the
number of shares of Common Stock acquirable upon complete conversion of this Note (without regard to any limitations on conversion contained herein) immediately before the date on which a record is taken for the grant, issuance or sale of such
Purchase Rights or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights. 
 (f) Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the events
described in this Section 1.6, the Borrower, at its expense, shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder of a certificate setting forth such adjustment or readjustment and showing in detail the
facts upon which such adjustment or readjustment is based. The Borrower shall, upon the written request at any time of the Holder, furnish to such Holder a like certificate setting forth (i) such adjustment or readjustment, (ii) the
Conversion Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon conversion of the Note. 
 1.7 Trading Market Limitations. Unless permitted by the applicable rules and regulations of the principal securities market on which the
Common Stock is then listed or traded, in no event shall the Borrower issue upon conversion of or otherwise pursuant to this Note and the other Notes issued pursuant to the Purchase Agreement more than the maximum number of shares of Common Stock
that the Borrower can issue pursuant to any rule of the principal United States securities market on which the Common Stock is then traded (the “Maximum Share Amount”), which shall be 19.99% of the total shares outstanding on the
Closing Date (as defined in the Purchase Agreement), subject to equitable adjustment from time to time for stock splits, stock dividends, combinations, capital reorganizations and similar events relating to the Common Stock occurring after the date
hereof. Once the Maximum Share Amount has been issued (the date of which is hereinafter referred to as the “Maximum Conversion Date”), if the Borrower fails to eliminate any prohibitions under applicable law or the rules or
regulations of any stock exchange, interdealer quotation system or other self-regulatory organization with jurisdiction over the Borrower or any of its securities on the 

  

 11 

 
Borrower’s ability to issue shares of Common Stock in excess of the Maximum Share Amount (a “Trading Market Prepayment Event”), in lieu
of any further right to convert this Note, and in full satisfaction of the Borrower’s obligations under this Note, the Borrower shall pay to the Holder, within fifteen (15) business days of the Maximum Conversion Date (the “Trading
Market Prepayment Date”), an amount equal to 130% times the sum of (a) the then outstanding principal amount of this Note immediately following the Maximum Conversion Date, plus (b) accrued and unpaid interest
on the unpaid principal amount of this Note to the Trading Market Prepayment Date, plus (c) Default Interest, if any, on the amounts referred to in clause (a) and/or (b) above, plus (d) any optional amounts that may
be added thereto at the Maximum Conversion Date by the Holder in accordance with the terms hereof (the then outstanding principal amount of this Note immediately following the Maximum Conversion Date, plus the amounts referred to in clauses
(b), (c) and (d) above shall collectively be referred to as the “Remaining Convertible Amount”). With respect to each Holder of Notes, the Maximum Share Amount shall refer to such Holder’s pro rata share
thereof determined in accordance with Section 4.8 below. In the event that the sum of (x) the aggregate number of shares of Common Stock issued upon conversion of this Note and the other Notes issued pursuant to the Purchase Agreement
plus (y) the aggregate number of shares of Common Stock that remain issuable upon conversion of this Note and the other Notes issued pursuant to the Purchase Agreement, represents at least one hundred percent (100%) of the Maximum
Share Amount (the “Triggering Event”), the Borrower will use its best efforts to seek and obtain Shareholder Approval (or obtain such other relief as will allow conversions hereunder in excess of the Maximum Share Amount) as soon as
practicable following the Triggering Event and before the Maximum Conversion Date. As used herein, “Shareholder Approval” means approval by the shareholders of the Borrower to authorize the issuance of the full number of shares of
Common Stock which would be issuable upon full conversion of the then outstanding Notes but for the Maximum Share Amount. 
 1.8 Status
as Shareholder. Upon submission of a Notice of Conversion by a Holder, (i) the shares covered thereby (other than the shares, if any, which cannot be issued because their issuance would exceed such Holder’s allocated portion of the
Reserved Amount or Maximum Share Amount) shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a Holder of such converted portion of this Note shall cease and terminate, excepting only the right to receive
certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Borrower to comply with the terms of this Note. Notwithstanding the foregoing, if
a Holder has not received certificates for all shares of Common Stock prior to the tenth (10th) business day after the expiration of the Deadline with respect to a conversion of any portion of this Note for any reason, then (unless the Holder
otherwise elects to retain its status as a holder of Common Stock by so notifying the Borrower) the Holder shall regain the rights of a Holder of this Note with respect to such unconverted portions of this Note and the Borrower shall, as soon as
practicable, return such unconverted Note to the Holder or, if the Note has not been surrendered, adjust its records to reflect that such portion of this Note has not been converted. In all cases, the Holder shall retain all of its rights and
remedies (including, without limitation, (i) the right to receive Conversion Default Payments pursuant to Section 1.3 to the extent required thereby for such Conversion Default and any subsequent Conversion Default and (ii) the right
to have the Conversion Price with respect to subsequent conversions determined in accordance with Section 1.3) for the Borrower’s failure to convert this Note. 
  

 12 

 ARTICLE II. CERTAIN COVENANTS 
 2.1 Distributions on Capital Stock. So long as the Borrower shall have any obligation under this Note, the Borrower shall not without the
Holder’s written consent (a) pay, declare or set apart for such payment, any dividend or other distribution (whether in cash, property or other securities) on shares of capital stock other than dividends on shares of Common Stock solely in
the form of additional shares of Common Stock or (b) directly or indirectly or through any subsidiary make any other payment or distribution in respect of its capital stock except for distributions pursuant to any shareholders’ rights plan
which is approved by a majority of the Borrower’s disinterested directors. 
 2.2 Restriction on Stock Repurchases. So
long as the Borrower shall have any obligation under this Note, the Borrower shall not without the Holder’s written consent redeem, repurchase or otherwise acquire (whether for cash or in exchange for property or other securities or otherwise)

 2.4 Sale of Assets. So long as the Borrower shall have any obligation under this Note, the Borrower shall not, without the Holder’s
written consent, sell, lease or otherwise dispose of any significant portion of its assets outside the ordinary course of business. Any consent to the disposition of any assets may be conditioned on a specified use of the proceeds of disposition.

 2.5 Advances and Loans. So long as the Borrower shall have any obligation under this Note, the Borrower shall not, without
the Holder’s written consent, lend money, give credit or make advances to any person, firm, joint venture or corporation, including, without limitation, officers, directors, employees, subsidiaries and affiliates of the Borrower, except loans,
credits or advances (a) in existence or committed on the date hereof and which the Borrower has informed Holder in writing prior to the date hereof, (b) made in the ordinary course of business or (c) not in excess of $50,000.

 2.6 Contingent Liabilities. So long as the Borrower shall have any obligation under this Note, the Borrower shall not,
without the Holder’s written consent, which shall not be unreasonably withheld, assume, guarantee, endorse, contingently agree to purchase or otherwise become liable upon the obligation of any person, firm, partnership, joint venture or
corporation, except by the endorsement of negotiable instruments for deposit or collection and except assumptions, guarantees, endorsements and contingencies (a) in existence or committed on the date hereof and which the Borrower has informed
Holder in writing prior to the date hereof, and (b) similar transactions in the ordinary course of business. 
  

 13 

 ARTICLE III. EVENTS OF DEFAULT 
 If any of the following events of default (each, an “Event of Default”) shall occur: 
 3.1 Failure to Pay Principal or Interest. The Borrower fails to pay the principal hereof or interest thereon when due on this Note, whether
at maturity, upon a Trading Market Prepayment Event pursuant to Section 1.7, upon acceleration or otherwise; 
 3.2 Conversion and
the Shares. The Borrower fails to issue shares of Common Stock to the Holder (or announces or threatens that it will not honor its obligation to do so) upon exercise by the Holder of the conversion rights of the Holder in accordance with the
terms of this Note (for a period of at least sixty (60) days, if such failure is solely as a result of the circumstances governed by Section 1.3 and the Borrower is using its best efforts to authorize a sufficient number of shares of
Common Stock as soon as practicable), fails to transfer or cause its transfer agent to transfer (electronically or in certificated form) any certificate for shares of Common Stock issued to the Holder upon conversion of or otherwise pursuant to this
Note as and when required by this Note or the Registration Rights Agreement, or fails to remove any restrictive legend (or to withdraw any stop transfer instructions in respect thereof) on any certificate for any shares of Common Stock issued to the
Holder upon conversion of or otherwise pursuant to this Note as and when required by this Note or the Registration Rights Agreement (or makes any announcement, statement or threat that it does not intend to honor the obligations described in this
paragraph) and any such failure shall continue uncured (or any announcement, statement or threat not to honor its obligations shall not be rescinded in writing) for ten (10) days after the Borrower shall have been notified thereof in writing by
the Holder; 
 3.3 Failure to Timely File Registration or Effect Registration. The Borrower fails to file the Registration
Statement within forty-five (45) days following the Closing Date (as defined in the Purchase Agreement) or obtain effectiveness with the Securities and Exchange Commission of the Registration Statement within one hundred thirty-five
(135) days following the Closing Date (as defined in the Purchase Agreement) or such Registration Statement lapses in effect (or sales cannot otherwise be made thereunder effective, whether by reason of the Borrower’s failure to amend or
supplement the prospectus included therein in accordance with the Registration Rights Agreement or otherwise) for more than ten (10) consecutive days or twenty (20) days in any twelve month period after the Registration Statement becomes
effective; 
 3.4 Breach of Covenants. The Borrower breaches any material covenant or other material term or condition
contained in Sections 1.3, 1.6 or 1.7 of this Note, or Sections 4(c), 4(e), 4(h), 4(i), 4(j) or 5 of the Purchase Agreement and such breach continues for a period of ten (10) days after written notice thereof to the Borrower from the Holder;

 3.5 Breach of Representations and Warranties. Any representation or warranty of the Borrower made herein or in any
agreement, statement or certificate given in writing pursuant hereto or in connection herewith (including, without limitation, the Purchase Agreement and the Registration Rights Agreement), shall be false or misleading in any material respect when
made and the breach of which has (or with the passage of time will have) a material adverse effect on the rights of the Holder with respect to this Note, the Purchase Agreement or the Registration Rights Agreement; 
  

 14 

 3.6 Receiver or Trustee. The Borrower or any subsidiary of the Borrower shall make an
assignment for the benefit of creditors, or apply for or consent to the appointment of a receiver or trustee for it or for a substantial part of its property or business, or such a receiver or trustee shall otherwise be appointed; 
 3.7 Judgments. Any money judgment, writ or similar process shall be entered or filed against the Borrower or any subsidiary of the Borrower
or any of its property or other assets for more than $50,000, and shall remain unvacated, unbonded or unstayed for a period of twenty (20) days unless otherwise consented to by the Holder, which consent will not be unreasonably withheld;

equivalent replacement exchange, the Nasdaq National Market, the Nasdaq SmallCap Market, the New York Stock Exchange, or the American Stock Exchange; or 
 3.10 Default Under Other Notes. An Event of Default has occurred and is continuing under any of the other Notes issued pursuant to the Purchase Agreement, then, upon the occurrence and during the
continuation of any Event of Default specified in Section 3.1, 3.2, 3.3, 3.4, 3.5, 3.7, 3.9, or 3.10, at the option of the Holders of a majority of the aggregate principal amount of the outstanding Notes issued pursuant to the Purchase
Agreement exercisable through the delivery of written notice to the Borrower by such Holders (the “Default Notice”), and upon the occurrence of an Event of Default specified in Section 3.6 or 3.8 (unless, under
Section 3.8, such proceeding shall be stayed within 30 days), the Notes shall become immediately due and payable and the Borrower shall pay to the Holder, in full satisfaction of its obligations hereunder, an amount equal to the greater of
(i) 130% times the sum of (w) the then outstanding principal amount of this Note plus (x) accrued and unpaid interest on the unpaid principal amount of this Note to the date of payment (the “Mandatory
Prepayment Date”) plus (y) Default Interest, if any, on the amounts referred to in clauses (w) and/or (x) plus (z) any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof or pursuant to
Section 2(c) of the Registration Rights Agreement (the then outstanding principal amount of this Note to the date of payment plus the amounts referred to in clauses (x), (y) and (z) shall collectively be known as the
“Default Sum”) or (ii) the “parity value” of the Default Sum to be prepaid, where parity value means (a) the highest number of shares of Common Stock issuable upon conversion of or otherwise pursuant to such
Default Sum in accordance with Article I, treating the Trading Day immediately preceding the Mandatory Prepayment Date as the “Conversion Date” for purposes of determining the lowest applicable Conversion Price, unless the Default Event
arises as a result of a breach in respect of a specific Conversion Date in which case such Conversion Date shall be the Conversion Date), multiplied by (b) the highest Closing Price for the Common Stock during 

  

 15 

 
the period beginning on the date of first occurrence of the Event of Default and ending one day prior to the Mandatory Prepayment Date (the “Default
Amount”) and all other amounts payable hereunder shall immediately become due and payable, all without demand, presentment or notice, all of which hereby are expressly waived, together with all costs, including, without limitation, legal
fees and expenses, of collection, and the Holder shall be entitled to exercise all other rights and remedies available at law or in equity. If the Borrower fails to pay the Default Amount within five (5) business days of written notice that
such amount is due and payable, then the Holder shall have the right at any time, so long as the Borrower remains in default (and so long and to the extent that there are sufficient authorized shares), to require the Borrower, upon written notice,
to immediately issue, in lieu of the Default Amount, the number of shares of Common Stock of the Borrower equal to the Default Amount divided by the Conversion Price then in effect. 
 ARTICLE IV. MISCELLANEOUS 
 4.1 Failure or Indulgence Not Waiver.
No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other right, power or privileges. All rights and remedies existing hereunder are cumulative to, and not exclusive of, any rights or remedies otherwise available. 
 4.2 Notices. Any notice herein required or permitted to be given shall be in writing and may be personally served or delivered by courier
or sent by United States mail and shall be deemed to have been given upon receipt if personally served (which shall include telephone line facsimile transmission) or sent by courier or three (3) days after being deposited in the United States
mail, certified, with postage pre-paid and properly addressed, if sent by mail. For the purposes hereof, the address of the Holder shall be as shown on the records of the Borrower; and the address of the Borrower shall be 10 East Baltimore Street,
Suite 1404, Baltimore, MD 21202, facsimile number: (410) 347-1542. Both the Holder and the Borrower may change the address for service by service of written notice to the other as herein provided. 
 4.3 Amendments. This Note and any provision hereof may only be amended by an instrument in writing signed by the Borrower and the Holder.
The term “Note” and all reference thereto, as used throughout this instrument, shall mean this instrument (and the other Notes issued pursuant to the Purchase Agreement) as originally executed, or if later amended or supplemented, then as
so amended or supplemented. 
 4.4 Assignability. This Note shall be binding upon the Borrower and its successors and assigns,
and shall inure to be the benefit of the Holder and its successors and assigns. Each transferee of this Note must be an “accredited investor” (as defined in Rule 501(a) of the 1933 Act). Notwithstanding anything in this Note to the
contrary, this Note may be pledged as collateral in connection with a bona fide margin account or other lending arrangement. 
  

 16 

 4.5 Cost of Collection. If default is made in the payment of this Note, the Borrower shall
pay the Holder hereof costs of collection, including reasonable attorneys’ fees. 
 4.6 Governing Law. THIS NOTE SHALL BE
ENFORCED, GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS. THE BORROWER HEREBY SUBMITS
TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK WITH RESPECT TO ANY DISPUTE ARISING UNDER THIS NOTE, THE AGREEMENTS ENTERED INTO IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY. BOTH PARTIES IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH SUIT OR PROCEEDING. BOTH PARTIES FURTHER AGREE THAT SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED IN EVERY RESPECT
EFFECTIVE SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR PROCEEDING. NOTHING HEREIN SHALL AFFECT EITHER PARTY’S RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW. BOTH PARTIES AGREE THAT A FINAL NON-APPEALABLE JUDGMENT IN ANY
SUCH SUIT OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON SUCH JUDGMENT OR IN ANY OTHER LAWFUL MANNER. THE PARTY WHICH DOES NOT PREVAIL IN ANY DISPUTE ARISING UNDER THIS NOTE SHALL BE RESPONSIBLE FOR ALL FEES
AND EXPENSES, INCLUDING ATTORNEYS’ FEES, INCURRED BY THE PREVAILING PARTY IN CONNECTION WITH SUCH DISPUTE. 
 4.7 Certain
Amounts. Whenever pursuant to this Note the Borrower is required to pay an amount in excess of the outstanding principal amount (or the portion thereof required to be paid at that time) plus accrued and unpaid interest plus Default Interest
on such interest, the Borrower and the Holder agree that the actual damages to the Holder from the receipt of cash payment on this Note may be difficult to determine and the amount to be so paid by the Borrower represents stipulated damages and not
a penalty and is intended to compensate the Holder in part for loss of the opportunity to convert this Note and to earn a return from the sale of shares of Common Stock acquired upon conversion of this Note at a price in excess of the price paid for
such shares pursuant to this Note. The Borrower and the Holder hereby agree that such amount of stipulated damages is not plainly disproportionate to the possible loss to the Holder from the receipt of a cash payment without the opportunity to

(iii) the Common Stock is trading at or below $.25 per share, the Borrower shall have the right, exercisable on not less than ten (10) Trading Days prior written notice to the Holders of the Notes (which notice may not be sent to the

Prepayment”) shall be delivered to the Holders of the Notes at their registered addresses appearing on the books and records of the Borrower and shall state (1) that the Borrower is exercising its right to prepay all of the Notes
issued on the Issue Date and (2) the date of prepayment (the “Optional Prepayment Notice”). On the date fixed for prepayment (the “Optional Prepayment Date”), the Borrower shall make payment of the Optional

(y) and (z) shall collectively be known as the “Optional Prepayment Sum”). Notwithstanding notice of an Optional Prepayment, the Holders shall at all times prior to the Optional Prepayment Date maintain the right to
convert all or any portion of the Notes in accordance with Article I and any portion of Notes so converted after receipt of an Optional Prepayment Notice and prior to the Optional Prepayment Date set forth in such notice and payment of the aggregate
Optional Prepayment Amount shall be deducted from the principal amount of Notes which are otherwise subject to prepayment pursuant to such notice. If the Borrower delivers an Optional Prepayment Notice and fails to pay the Optional Prepayment Amount
due to the Holders of the Notes within two (2) business days following the Optional Prepayment Date, the Borrower shall forever forfeit its right to redeem the Notes pursuant to this Section 5.1.
