defined below), the Subscriber may, on or prior to the Closing, at its sole and absolute discretion, elect not to purchase the Units and provide instructions to the Company to receive the full and immediate refund of the Aggregate Purchase Price. In
the event the Closing does not take place because of (i) the election not to purchase the Units by the Subscriber or (ii) the failure to effectuate the Initial Closing (as defined below) on or prior to March 27, 2015 (unless extended
in the discretion of the Board of Directors) for any reason or no reason, this Agreement and any other Transaction Documents shall thereafter be terminated and have no force or effect, and the parties shall take all steps, including the execution of
instructions to the Company, to ensure that the Aggregate Purchase Price shall promptly be returned or caused to be returned to the Subscriber without interest thereon or deduction therefrom.

Subscribers. Officers, directors and affiliates of the Company and the placement agent, if any, may purchase Units in the Offering.

(c)
Following Acceptance or Rejection. The Subscriber acknowledges and agrees that this Agreement and any other documents delivered in connection herewith will be held by the Company. Prior to the Companys execution, in the event that this
Agreement is not accepted by the Company for whatever reason, which the

Company expressly reserves the right to do, this Agreement, the Aggregate Purchase Price received (without interest thereon) and any other documents delivered in connection herewith will be
returned to the Subscriber at the address of the Subscriber as set forth in this Agreement. If this Agreement is accepted by the Company, the Company is entitled to treat the Aggregate Purchase Price received as an interest free loan to the Company
until such time as the Subscription is accepted.

(d) Favored Nations Provision. For any Subscriber that elected to receive
Shares (and not Preferred Shares) in connection with its purchase of Units hereunder, for a period beginning on the Closing Date and ending on the date that is the earlier of (i) twenty-four (24) months from the Final Closing Date,
(ii) the date the Company consummates a financing (excluding proceeds from this Offering) in which the Company receives gross proceeds of at least Ten Million Dollars ($10,000,000) and (iii) the date the Companys Common Stock is

into account the shares of Common Stock issuable upon exercise of such options) after the Final Closing Date pursuant to this clause (i) do not, in the aggregate, exceed more than 7,116,204 shares of Common Stock, in the aggregate (including
options) (as adjusted for stock splits, combinations and similar transactions) and (B) the exercise price of any such options is not lowered after issuance by subsequent amendment thereof, none of such options are amended subsequent to issuance
to increase the number of shares issuable thereunder and none of the terms or conditions of any such options are subsequent to issuance otherwise materially changed in any manner that adversely affects any of the Subscribers; (ii) the issuance
of shares of Common Stock issued upon the conversion or exercise of Convertible Securities or contractual agreements (other than options to purchase Common Stock or other equity incentive awards issued pursuant to an Approved Stock Plan that are
covered by clause (i) above) issued prior to the date hereof, provided that the conversion price of any such Convertible Securities (other than options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by
clause (i) above) is not lowered by subsequent amendment, none of such Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) are
subsequently amended to increase the number of shares issuable thereunder and none of the terms or conditions of any such Convertible Securities (other than options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered
by clause (i) above) are otherwise materially changed in any manner that adversely affects any of the Subscribers; (iii) the shares of Common Stock issuable upon conversion of the Preferred Shares or the Warrants and (iv) the
issuances set forth on Schedule 2(d) (collectively, the foregoing (i) through (iv) are Excepted Issuances), if at any time the Company shall issue any Common Stock or securities convertible into or
exercisable for shares of Common Stock (or modify any of the foregoing which may be outstanding) to any person or entity at a price per share or conversion or exercise price per share which shall be less than $0.75 per share, being the per share
price of the Shares hereunder (disregarding any value attributable to the Warrants) or as in effect at such time, without consent of Subscribers holding at least 60% of the then outstanding Units (the Required Approval) (the
Lower Price Issuance) and other than with regard to Excepted Issuances, then the Company shall issue the Subscriber such number of additional Shares to reflect such lower price for the Shares such that the Subscriber shall hold
such number of Shares, in total, had Subscriber paid a per Share price equal to the Lower Price Issuance (with any fractional Shares rounded down to the nearest whole number). Common Stock issued or issuable by the Company for no consideration
or for consideration that cannot be determined at the time of issue will be deemed issuable or to have been issued for $0.01 per share of Common Stock. All Favored Nations rights of a Subscriber who elected to purchase Preferred
Shares shall be governed by the Series E Certificate of Designation. Notwithstanding anything herein or in any other agreement to the contrary, the Company shall only be required to make a single adjustment with respect to any Lower Price
Issuance, regardless of the existence of multiple basis therefore. For purposes of this Section 2(d), Approved Stock Plan shall mean any employee benefit plan which has been approved by the board of directors of the Company
on or prior to the date hereof pursuant to which shares of Common Stock and standard options to purchase Common Stock may be issued to any employee, officer or director for services provided to the Company in their capacity as such (including,

(e) Extraordinary Events Regarding Common Stock. In the event that the Company shall
(a) issue additional shares of Common Stock as a dividend or other distribution on outstanding Common Stock, (b) subdivide its outstanding shares of Common Stock, or (c) combine its outstanding shares of the Common Stock into a
smaller number of shares of Common Stock, then, in each such event, the Purchase Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Purchase Price by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the
Purchase Price then in effect. The Purchase Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein. The number of Units that the Subscriber shall thereafter be entitled to
receive (including number of shares of Conversion Shares or Warrant Shares the Subscriber may thereafter be entitled to receive upon conversion of the Preferred Shares or exercise of the Warrants, as the case may be) shall be adjusted to a number
determined by multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section) be issuable on such conversion or exercise by a fraction of which (a) the numerator is the Purchase Price that would
otherwise (but for the provisions of this Section) be in effect, and (b) the denominator is the Purchase Price then in effect.

(f)
Certificate as to Adjustments. In each case of any adjustment or readjustment in (i) the Shares, (ii) the Preferred Shares, (iii) the number of Conversion Shares issuable upon conversion of the Preferred Shares (iii) the
number of Warrant Shares issuable upon the exercise of the Warrants, (iv) the exercise price of the Warrants and/or (v) the conversion price of the Preferred Shares, the Company, at its expense, will promptly cause its Chief Financial
Officer or other appropriate designee to compute such adjustment or readjustment in accordance with the terms hereof and of the Series E Certificate of Designation or the Warrant, as applicable, and prepare a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company will forthwith mail a copy of each such certificate to the Subscriber.



|3. | THE SUBSCRIBERS REPRESENTATIONS, WARRANTIES AND COVENANTS
|-- | ----------------------------------------------------------

Each Subscriber,
severally and not jointly, hereby acknowledges, agrees with and represents, warrants and covenants to the Company, as follows:

(a) The
Subscriber has full power and authority to enter into this Agreement, the execution and delivery of which has been duly authorized, if applicable, and this Agreement constitutes a valid and legally binding obligation of the Subscriber, except as may
be limited by bankruptcy, reorganization, insolvency, moratorium and similar laws of general application relating to or affecting the enforcement of rights of creditors, and except as enforceability of the obligations hereunder are subject to
general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or law).

(b) The
Subscriber acknowledges its understanding that the Offering and sale of the Securities is intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) of the Securities Act and the provisions of Regulation D
promulgated thereunder (Regulation D). In furtherance thereof, the Subscriber represents and warrants to the Company and its affiliates as follows:

(i) The Subscriber realizes that the basis for the exemption from registration may not be available if, notwithstanding the
Subscribers representations contained herein, the Subscriber is merely acquiring the Securities for a fixed or determinable period in the future, or for a market rise, or for sale if the market does not rise. The Subscriber does not have any
such intention.

(ii) The Subscriber realizes that the basis for exemption would not be available if the Offering is part
of a plan or scheme to evade registration provisions of the Securities Act or any applicable state or federal securities laws, except sales pursuant to a registration statement or sales that are exempted under the Securities Act.



- 5 -



---

(iii) The Subscriber is acquiring the Securities solely for the Subscribers
own beneficial account, for investment purposes, and not with a view towards, or resale in connection with, any distribution of the Securities.

(iv) The Subscriber has the financial ability to bear the economic risk of the Subscribers investment, has adequate means
for providing for its current needs and contingencies, and has no need for liquidity with respect to an investment in the Company.

(v) The Subscriber and the Subscribers attorney, accountant, purchaser representative and/or tax advisor, if any
(collectively, the Advisors) has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of a prospective investment in the Securities. If other than an individual, the
Subscriber also represents it has not been organized solely for the purpose of acquiring the Securities.

(vi) The
Subscriber (together with its Advisors, if any) has received all documents requested by the Subscriber, if any, and has carefully reviewed them and understands the information contained therein, prior to the execution of this Agreement.

(c) The Subscriber is not relying on the Company or any of its employees, agents, sub-agents or advisors with respect to the legal, tax,
economic and related considerations involved in this investment. The Subscriber has relied on the advice of, or has consulted with, only its Advisors. Each Advisor, if any, has disclosed to the Subscriber in writing (a copy of which is annexed to
this Agreement) the specific details of any and all past, present or future relationships, actual or contemplated, between the Advisor and the Company or any affiliate or sub-agent thereof.

(d) The Subscriber has carefully considered the potential risks relating to the Company and a purchase of the Securities, and fully
understands that the Securities are a speculative investment that involves a high degree of risk of loss of the Subscribers entire investment. Among other things, the Subscriber has carefully considered each of the risks described under the
heading Risk Factors in the Companys SEC Documents (as defined below) and any additional disclosures in the nature of Risk Factors described herein.

(e) The Subscriber will not sell or otherwise transfer any Securities without registration under the Securities Act or an exemption therefrom,
and fully understands and agrees that the Subscriber must bear the economic risk of its purchase because, among other reasons, the Securities have not been registered under the Securities Act or under the securities laws of any state and, therefore,
cannot be resold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Securities Act and under the applicable securities laws of such states, or an exemption from such registration is available. In
particular, the Subscriber is aware that the Securities are restricted securities, as such term is defined in Rule 144 promulgated under the Securities Act (Rule 144), and they may not be sold pursuant to Rule 144
unless all of the conditions of Rule 144 are met. The Subscriber also understands that the Company is under no obligation to register the Securities on behalf of the Subscriber or to assist the Subscriber in complying with any exemption from
registration under the Securities Act or applicable state securities laws. The Subscriber understands that any sales or transfers of the Securities are further restricted by state securities laws and the provisions of this Agreement.

(f) No oral or written representations or warranties have been made, or information furnished, to the Subscriber or its Advisors, if any, by
the Company or any of its officers, employees, agents, sub-agents, affiliates, advisors or subsidiaries in connection with the Offering, other than any representations of the Company contained herein, and in subscribing for the Units the Subscriber
is not relying upon any representations other than those contained herein.

(g) The Subscribers overall commitment to investments
that are not readily marketable is not disproportionate to the Subscribers net worth, and an investment in the Securities will not cause such overall commitment to become excessive.

(h) The Subscriber understands and agrees that the certificates for the Securities shall bear
substantially the following legend:

[NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE

REQUESTED BY THE COMPANY), IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING,

(i) while a registration statement covering the resale of such Securities is effective under the Securities Act, (ii) following any sale of such Securities pursuant to Rule 144 (assuming the transferor is not an affiliate of the Company),
(iii) if such Securities are eligible to be sold, assigned or transferred under Rule 144 and the Subscriber is not an affiliate of the Company (provided that the Subscriber provides the Company with reasonable assurances that such Securities
are eligible for sale, assignment or transfer under Rule 144 which shall not include an opinion of the Subscribers counsel), (iv) in connection with a sale, assignment or other transfer (other than under Rule 144), provided that the
Subscriber provides the Company with an opinion of counsel (at the expense of the Company), in a form generally acceptable to the Company, to the effect that such sale, assignment or transfer of the Securities may be made without registration under
the applicable requirements of the Securities Act or (v) if such legend is not required under applicable requirements of the Securities Act (including, without limitation, controlling judicial interpretations and pronouncements issued by the
SEC). If a legend is not required pursuant to the foregoing, the Company shall no later than three (3) business days following the delivery by the Subscriber to the Company or the transfer agent (with notice to the Company) of a legended
certificate representing such Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from the Subscriber
as may be required above in this Section 3(i), as directed by the Subscriber, either: (A) provided that the Companys transfer agent is participating in the DTC Fast Automated Securities Transfer Program and such Securities are shares
of Shares, Conversion Shares or Warrant Shares, credit the aggregate number of shares of Common Stock to which the Subscriber shall be entitled to the Subscribers or its designees balance account with DTC through its Deposit/Withdrawal

approved the Securities or passed upon or endorsed the merits of the Offering. There is no government or other insurance covering any of the Securities.

(k) The Subscriber and its Advisors, if any, have had a reasonable opportunity to ask questions of and receive answers from a person or
persons acting on behalf of the Company concerning the Offering and the business, financial condition, results of operations and prospects of the Company, and all such questions have been answered to the full satisfaction of the Subscriber and its
Advisors, if any.

(l) (i) In making the decision to invest in the Securities the Subscriber has relied solely upon the information
provided by the Company in the Transaction Documents. To the extent necessary, the Subscriber has



- 7 -



---

retained, at its own expense, and relied upon appropriate professional advice regarding the investment, tax and legal merits and consequences of this Agreement and the purchase of the Securities
hereunder. The Subscriber disclaims reliance on any statements made or information provided by any person or entity in the course of Subscribers consideration of an investment in the Securities other than the Transaction Documents.

(ii) The Subscriber represents and warrants that: (i) the Subscriber was contacted regarding the sale of the Securities by the Company
(or an authorized agent or representative thereof) with whom the Subscriber had a prior substantial pre-existing relationship and (ii) no Securities were offered or sold to it by means of any form of general solicitation or general advertising,

circuit, or generally available; or (B) attend any seminar meeting or industry investor conference whose attendees were invited by any general solicitation or general advertising; or (C) observe any website or filing of the Company with
the SEC in which any offering of securities by the Company was described and as a result learned of any offering of securities by the Company.

(m) The Subscriber has taken no action that would give rise to any claim by any person for brokerage commissions, finders fees or the
like relating to this Agreement or the transactions contemplated hereby.

(n) The Subscriber is not relying on the Company or any of its
employees, agents, or advisors with respect to the legal, tax, economic and related considerations of an investment in the Securities, and the Subscriber has relied on the advice of, or has consulted with, only its own Advisors.

(o) The Subscriber acknowledges that any estimates or forward-looking statements or projections furnished by the Company to the Subscriber
were prepared by the management of the Company in good faith, but that the attainment of any such projections, estimates or forward-looking statements cannot be guaranteed by the Company or its management and should not be relied upon.

(p) No oral or written representations have been made, or oral or written information furnished, to the Subscriber or its Advisors, if any, in
connection with the Offering that are in any way inconsistent with the information contained herein.

(q) (For ERISA plans only) The
fiduciary of the ERISA plan (the Plan) represents that such fiduciary has been informed of and understands the Companys investment objectives, policies and strategies, and that the decision to invest plan assets (as
such term is defined in ERISA) in the Company is consistent with the provisions of ERISA that require diversification of plan assets and impose other fiduciary responsibilities. The Subscriber or Plan fiduciary (i) is responsible for the
decision to invest in the Company; (ii) is independent of the Company and any of its affiliates; (iii) is qualified to make such investment decision; and (iv) in making such decision, the Subscriber or Plan fiduciary has not relied

Investor is deemed to be an institution with assets in excess of $5,000,000 or individuals with a net worth in excess of $1,000,000 (excluding such persons residence) or annual income exceeding $200,000 or $300,000 jointly with his or
her spouse.

(t) The Subscriber, either alone or together with its representatives, has such knowledge, sophistication and experience in
business and financial matters so as to be capable of evaluating the merits and risks of the Offering, and has so evaluated the merits and risks of such investment. The Subscriber has not authorized any person or entity to act as its Purchaser
Representative (as that term is defined in Regulation D of the General Rules and Regulations under the Securities Act) in connection with the Offering. The Subscriber is able to bear the economic risk of an investment in the Securities and, at the
present time, is able to afford a complete loss of such investment.

---

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 order to
make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company included in the SEC Documents complied in all material respects with

expected to occur or exist, with respect to the Company, any of its Subsidiaries or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition (financial or otherwise) that
(i) would be required to be disclosed by the Company under applicable securities laws on a registration statement on Form S-1 filed with the SEC relating to an issuance and sale by the Company of its Common Stock and which has not been publicly

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 been refused any

employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer or other
key employee (as the case may be) does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all federal, state, local and foreign
laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably
be expected to result in a Material Adverse Effect.

interfere with the use made of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company or any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with
such exceptions as are not material and do not interfere with the use made of such property and buildings by the Company or any of its Subsidiaries.

the exemptions proved by Rule 144 under the Securities Act.

(b) Shareholder Rights Plan. No claim will be made or enforced by the
Company or, to the knowledge of the Company, any other person that any Subscriber is an Acquiring Person under any shareholder rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that any
Subscriber could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Subscribers.

(c) Securities Laws Disclosure; Publicity. The Company shall by 8:30 a.m. (New York City time) (a) on the first Business Day after
this Agreement has been executed, issue a press release disclosing the material terms of the transactions contemplated hereby and (b) within four (4) Business Days after this Agreement has been executed, file a Current Report on Form 8-K

- 20 -



---

Subscriber in any filing with the SEC or any regulatory agency, without the prior written consent of such Subscriber, except to the extent such disclosure is required by law or in connection with
the Registration Rights of the Company set forth in Section 7 herein, in which case the Company shall provide the Subscribers with prior notice of such disclosure. The Company understands that any such disclosure shall cause irreparable harm
and each Subscriber shall be entitled to injunctive relief and liquidated damages in connection therewith.

Company shall not, and shall use its best efforts to ensure that no affiliate of the Company shall, after the date hereof, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security that would be integrated with

(i) The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in
such amount as may then be required to fulfill its obligations in full under the Transaction Documents, but not less than 125% of the maximum number of shares of Common Stock issuable pursuant to the Transaction Documents (the Required
Minimum).

than the Required Minimum on such date, then the Board of Directors shall approve the amendment of the Companys Charter to increase the number of authorized but unissued shares of Common Stock to at least the Required Minimum and submit such
amendment to the Companys stockholders for approval, as soon as possible and in any event not later than the 60th day after such date.

approved for listing or quotation on such Principal Market as soon as possible thereafter, (iii) provide to the Subscribers evidence of such listing or quotation and (iv) maintain the listing or quotation of such Common Stock on any date

a Principal Market for as long as any Subscriber holds Securities, and will comply in all material respects with the Companys reporting, filing and other obligations under the bylaws or rules of the Principal Market at least until five years
after the Closing Date. In the event the aforedescribed listing is not continuously maintained for five years after the Closing Date (a Listing Default), then in addition to any other rights the Subscribers may have hereunder or

the Company shall pay to each Subscriber an amount in cash, as partial liquidated damages and not as a penalty, equal to 1% of (x) aggregate Subscription Amount of Shares or Conversion Shares calculated on an as converted basis, as
the case may be held by such Subscriber on the date of a Listing Default and (y) the aggregate purchase price of Warrant Shares held by such Subscriber on the day of a Listing Default and on every thirtieth day (pro-rated for periods less than

Company regarding the willingness to accept receipt of such material non-public information and acknowledges the confidentiality and use of such information and the Companys covenant to
file a further SEC filing or report and the period in which such information shall remain confidential or be required to not be disclosed. The Company understands and confirms that each Subscriber shall be relying on the foregoing covenant in
effecting transactions in securities of the Company. In addition, effective upon the filing of the 8-K Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral,
between the Company and any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents, on the one hand, and the Subscriber or any of its affiliates on the other hand, shall terminate.

(h) Right of Participation. The Company acknowledges and agrees that the right set forth in this Section 5(h) is a right granted
by the Company, separately, to each Subscriber.

(i) At least five (5) trading days prior to any proposed or intended sale by the
Company of its Common Stock or other securities or equity linked debt obligations (each, a Subsequent Placement), the Company shall deliver to each Subscriber a written notice of its proposal or intention to effect a Subsequent
Placement (each such notice, a Pre-Notice), which Pre-Notice shall not contain any information (including, without limitation, material, non-public information) other than: (A) a statement that the Company proposes or intends
to effect a Subsequent Placement, (B) a statement that the statement in clause (A) above does not constitute material, non-public information and (C) a statement informing such Subscriber that it is entitled to receive an Offer Notice
(as defined below) with respect to such Subsequent Placement upon its written request. Upon the written request of a Subscriber within five (5) business days after the Companys delivery to such Subscriber of such Pre-Notice, and only upon
a written request by such Subscriber, the Company shall promptly, but no later than one (1) business day after such request, deliver to such Subscriber an irrevocable written notice (the Offer Notice) of any proposed or
intended issuance or sale or exchange (the Offer) of the securities being offered (the Offered Securities) in a Subsequent Placement, which Offer Notice shall (I) identify and describe the Offered
Securities, (II) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (III) identify the persons (if known) to which or with which
the Offered Securities are to be offered, issued, sold or exchanged and (IV) offer to issue and sell to or exchange with such Subscriber in accordance with the terms of the Offer such Subscribers pro rata portion of 100% of the Offered
Securities, provided that the number of Offered Securities which such Subscriber shall have the right to subscribe for under this Section 5(h) shall be (x) based on such Subscribers pro rata portion of the aggregate original amount
of the Units purchased hereunder by all Subscribers (the Basic Amount), and (y) with respect to each Subscriber that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the
Basic Amounts of other Subscribers as such Subscribers shall indicate it will purchase or acquire should the other Subscribers subscribe for less than their Basic Amounts (the Undersubscription Amount).

(ii) To accept an Offer, in whole or in part, such Subscriber must deliver a written notice to the Company prior to the end of the fifth (5th) Business Day after such Subscribers receipt of the Offer Notice (the Offer Period), setting forth the portion of such Subscribers Basic Amount that such
Subscriber elects to purchase and, if such Subscriber shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Subscriber elects to purchase (in either case, the Notice of Acceptance). If
the Basic Amounts subscribed for by all Subscribers are less than the total of all of the Basic Amounts, then such Subscriber who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the
Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed
for (the Available Undersubscription Amount), such Subscriber who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of
such Subscriber bears to the total Basic Amounts of all Subscribers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent it deems reasonably necessary. Notwithstanding the foregoing, if the Company
desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to each Subscriber a new Offer Notice and the Offer Period shall expire on the fifth (5th) Business Day after such Subscribers receipt of such new Offer Notice.

(iii) The Company shall have five (5) Business Days from the expiration of the Offer Period above (A) to offer, issue, sell or
exchange all or any part of such Offered Securities as to which a Notice of



- 22 -



---

Acceptance has not been given by a Subscriber (the Refused Securities) pursuant to a definitive agreement(s) (the Subsequent Placement Agreement), but only
to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less
favorable to the Company than those set forth in the Offer Notice and (B) to publicly announce (I) the execution of such Subsequent Placement Agreement, and (II) either (x) the consummation of the transactions contemplated by such
Subsequent Placement Agreement or (y) the termination of such Subsequent Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated therein
filed as exhibits thereto.

(iv) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be
in the manner and on the terms specified in Section 5(h)(iii) above), then such Subscriber may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an
amount that shall be not less than the number or amount of the Offered Securities that such Subscriber elected to purchase pursuant to Section 5(h)(ii)1(a)(ii) above multiplied by a fraction, (A) the numerator of which shall be the number
or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Subscribers pursuant to this Section 5(h) prior to such reduction) and (B) the denominator of
which shall be the original amount of the Offered Securities. In the event that any Subscriber so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more
than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Subscribers in accordance with Section 5(h)(i) above.

(v) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Subscriber shall acquire from
the Company, and the Company shall issue to such Subscriber, the number or amount of Offered Securities specified in its Notice of Acceptance. The purchase by such Subscriber of any Offered Securities is subject in all cases to the preparation,
execution and delivery by the Company and such Subscriber of a separate purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to such Subscriber and its counsel.

(vi) Any Offered Securities not acquired by a Subscriber or other persons in accordance with this Section 5(h) may not be issued, sold or
exchanged until they are again offered to such Subscriber under the procedures specified in this Agreement.

(vii) The Company and each
Subscriber agree that if any Subscriber elects to participate in the Offer, neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the Subsequent Placement
Documents) shall include any term or provision in addition to any terms or conditions contained in this Agreement whereby such Subscriber shall be required to agree to any restrictions on trading as to any securities of the Company or be
required to consent to any amendment to or termination of, or grant any waiver, release or the like under or in connection with, any agreement previously entered into with the Company or any instrument received from the Company.

(viii) Notwithstanding anything to the contrary in this Section 5(h) and unless otherwise agreed to by such Subscriber, the Company shall
either confirm in writing to such Subscriber that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case, in such a manner such that such
Subscriber will not be in possession of any material, non-public information, by the fifth (5th) business day following delivery of the Offer Notice. If by such fifth (5th) business day, no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction has been received
by such Subscriber, such transaction shall be deemed to have been abandoned and such Subscriber shall not be in possession of any material, non-public information with respect to the Company or any of its subsidiaries. Should the Company decide to
pursue such transaction with respect to the Offered Securities, the Company shall provide such Subscriber with another Offer Notice in accordance with, and subject to, the terms of this Section 5(h) and such Subscriber will again have the right

Effectiveness Date that the registration statement has not been declared effective; provided, however, that the Company shall not be obligated to pay any such liquidated damages if the Company is unable to fulfill its registration obligations as a
result of rules, regulations, positions or releases issued or actions taken by the SEC pursuant to its authority with respect to Rule 415, provided the Company registers at such time the maximum number of shares of Common Stock
permissible upon consultation with the staff of the SEC.

The description of registration rights is qualified in its entirety by reference
to Registration Rights Agreement annexed hereto as Exhibit E (the Registration Rights Agreement).

Subscriber or the Company, deemed amended and modified in an economically and legally equivalent manner such that the Subscriber shall receive the benefit of the more favorable terms contained in such Subscription Document. Notwithstanding the
foregoing, the Company agrees, at its expense, to take such other actions (such as entering into amendments to the Transaction Documents) as the Subscriber may reasonably request to further effectuate the foregoing.

those transferees) in this Offering allocable to the securities acquired by such transferee(s).
