COMMON STOCK PURCHASE AGREEMENT

This COMMON STOCK PURCHASE AGREEMENT this (Agreement), dated as of March 22, 2006 by and between FiberNet Telecom Group, Inc., a
Delaware corporation (the Company), and the purchasers listed on Exhibit A hereto (each a Purchaser and collectively, the Purchasers), for the purchase and sale of shares of the
Companys common stock, par value $.001 per share (the Common Stock) by the Purchasers.

The parties hereto agree
as follows:

ARTICLE I

Purchase and Sale of Common Stock and Warrants

Section 1.1 Purchase and Sale of Common Stock and Warrants.

(a) Upon the following terms and conditions, the Company shall issue and sell to the Purchasers, and the Purchasers shall purchase from the Company, an
aggregate of 1,050,000 shares of Common Stock (the Shares) at a price per share of $2.10 (the Per Share Purchase Price) for an aggregate purchase price of $2,205,000 (the Purchase Price). The
Company and the Purchasers are executing and delivering this Agreement in accordance with and in reliance upon the exemption from securities registration afforded by Section 4(2) of the U.S. Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder (the Securities Act), including Regulation D (Regulation D), and/or upon such other exemption from the registration requirements of the Securities Act as may be available with
respect to any or all of the investments to be made hereunder.

(b) Upon the following terms and conditions, the Purchasers shall be issued
Warrants, in substantially the form attached hereto as Exhibit B (the Warrants), to purchase the number of shares of Common Stock set forth opposite such Purchasers name on Exhibit A hereto. The Warrants shall
have an exercise price equal to $2.64 per share and shall be exercisable on the date that is six months and one day following the Closing Date. Any shares of Common Stock issuable upon exercise of the Warrants (and such shares when issued) are
herein referred to as the Warrant Shares. The Shares, the Warrants and the Warrant Shares are sometimes collectively referred to herein as the Securities.

Section 1.2 Purchase Price and Closing.

The Company
agrees to issue and sell to the Purchasers and, in consideration of and in express reliance upon the representations, warranties, covenants, terms and conditions of this Agreement, the Purchasers, severally but not jointly, agree to purchase the
number of Shares and Warrants, in each case, set forth opposite their respective names on Exhibit A. The closing of the purchase and sale of the Shares and Warrants to be acquired by the Purchasers from the Company under this Agreement shall take
place at the offices of the Company (the Closing) at 10:00 a.m., New York time (i) on or before March 24, 2006 or (ii) at such other time and place or on such date as the Purchasers and the Company may agree upon (the
Closing Date), provided, that in each such case, all of the conditions set forth in Article IV hereof and applicable to the



1



---

Closing shall have been fulfilled or waived in accordance herewith. At the Closing, the Company shall deliver or cause to be delivered to each Purchaser
(i) a certificate registered in the name of the Purchaser representing the number of Shares that such Purchaser is purchasing pursuant to the terms hereof, (ii) a Warrant to purchase such number of shares of Common Stock as is set forth
opposite the name of such Purchaser on Exhibit A and (iii) any other deliveries as required by Article IV. At the Closing, each Purchaser shall deliver its Purchase Price by wire transfer to an account designated by the Company.

Section 1.3 Anti-Dilution Protection.

(a) Except for the issuance of Additional Shares (as defined in Section 1.3(d)), for the fourteen-month period immediately following the Closing Date the Company covenants and agrees that it shall not enter into any Subsequent
Financing (as defined below) at a price per share or conversion price less than the Per Share Purchase Price unless it has received (i) Stockholder Approval (as defined in Section 1.3(e)) in accordance with Section 1.3(e) or
(ii) the prior written consent of the Qualified Purchasers (as defined in Section 1.3(d)) holding at least a majority of all Shares then held by the Qualified Purchasers. For purposes hereof, a Subsequent Financing means
any offer or sale to, or exchange with (or other type of distribution to) any third party, of Common Stock or any securities convertible, exercisable or exchangeable into Common Stock, including convertible debt securities.

(b) Notwithstanding the terms and provisions of Section 1.3(a) to the contrary, if during the fourteen-month period immediately following the
Closing Date, the Company sells Additional Shares (as defined below) in a Subsequent Financing (the Dilutive Issuance) at a price per share less than the Per Share Purchase Price (the Share Anti-Dilution Price),
then the Company shall promptly offer to sell to each Qualified Purchaser a number of additional shares of Common Stock (the New Shares) equal to:

(i) the product of (x) the number of Shares owned by such Qualified Purchaser on the closing date of the Dilutive Issuance and
(y) the quotient obtained by dividing the Per Share Purchase Price by the Share Anti-Dilution Price, minus

(ii) the
number of Shares owned by such Qualified Purchaser on the closing date of the Dilutive Issuance.

(c) The purchase price for each New Share
will be $0.001. The number of New Shares issued to each Qualified Purchaser pursuant to this Section 1.3 will be rounded down to the nearest whole share, and no fractional shares will be issued. The Company shall give each Qualified Purchaser
prompt notice of any event that requires an adjustment pursuant to this Section 1.3 in accordance with Section 7.4.

(d) As used
herein, the term Qualified Purchaser means any Purchaser that owns not less than 25% of the Shares that it purchased on the Closing Date. As used herein, the term Additional Shares means all shares of Common
Stock issued by the Company, except: (1) shares of Common Stock to be issued to strategic partners and/or in connection with a strategic merger or acquisition; (2) shares of Common Stock or the issuance of options to purchase shares of
Common Stock to employees, officers, directors, consultants and vendors in accordance with

the Companys equity incentive plan; (3) the issuance of securities pursuant to a bona fide firm underwritten public offering of the Companys
securities; (4) the conversion or exercise of convertible or exercisable securities issued or outstanding on or prior to the date hereof; (5) up to an aggregate of 250,000 shares of Common Stock (as may be adjusted for any stock splits or
combinations of the Common Stock) to be issued to settle pending and threatened litigation against the Company; (6) up to an aggregate of 500,000 shares of Common Stock (as may be adjusted for any stock splits or combinations of the Common
Stock) to be issued in satisfaction of the Companys outstanding liabilities, including, but not limited to, currently existing obligations under the Companys real estate leases; and (7) equity securities to be issued upon the
conversion of debt securities of the Company at a conversion price above the Per Share Purchase Price.

(e) If the Company is prohibited by
Rule 4350(i) of the National Association of Securities Dealers, Inc. (NASD), or any successor or similar rule, or the rules or regulations of any other securities exchange on which the Common Stock is then listed or traded, from
issuing a number of New Shares pursuant to this Section 1.3 in excess of a prescribed amount (the Cap Amount) without stockholder approval or otherwise, then the Company shall not issue New Shares in excess of the Cap Amount.
Assuming solely for purposes of this paragraph that such Rule 4350(i) or similar rule is applicable, the Cap Amount shall be 19.99% of the Common Stock outstanding immediately prior to the Closing Date. The Cap Amount shall be allocated pro rata to

Company.

The Company hereby represents and warrants to the Purchasers as follows, as of the date hereof and the Closing Date, except

on Schedule 2.1(g) hereto. The Company and each such Subsidiary (as defined in Section 2.1(g)) is duly qualified as a foreign corporation to do
business and is in good standing in every jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary except for any jurisdiction(s) (alone or in the aggregate) in which the failure to be so
qualified will not have a Material Adverse Effect. For the purposes of this Agreement, Material Adverse Effect means any effect on the business, operations, properties, prospects or financial condition of the Company that is
material and adverse to the Company and its Subsidiaries, taken as a whole, and any condition, circumstance or situation that would prohibit the Company from entering into and performing any of its obligations hereunder and under the other
Transaction Documents (as defined below).

(b) Authorization; Enforcement. The Company has the requisite corporate
power and authority to enter into and perform this Agreement, the Warrants and that certain Registration Rights Agreement by and among the Company and the Purchasers, dated as of the date hereof, substantially in the form of Exhibit C

execution, delivery and performance of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly and validly authorized by all necessary corporate action, and, except as set forth on
Schedule 2.1(b), no further consent or authorization of the Company, its Board of Directors or stockholders is required. When executed and delivered by the Company, each of the Transaction Documents shall constitute a valid and binding
obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, reorganization, moratorium, liquidation, conservatorship, receivership or similar laws
relating to, or affecting generally the enforcement of, creditors rights and remedies or by other equitable principles of general application.

(c) Capitalization. The authorized capital stock of the Company as of the date of this Agreement consists of 2,000,000,000 shares of Common Stock, of which 5,256,900 were issued and outstanding as of
January 31, 2006, and 20,000,000 shares of preferred stock, par value $.001 per share, of which none were issued and outstanding as of January 31, 2006. All of the outstanding shares of the Common Stock and any other outstanding security
of the Company have been duly and validly authorized. Except as set forth in this Agreement and as set forth on Schedule 2.1(c) hereto, no shares of Common Stock or any other security of the Company are entitled to preemptive rights or
registration rights and there are no outstanding options, warrants, scrip, rights to subscribe to, call or commitments of any character whatsoever relating to, or securities or rights convertible into, any shares of capital stock of the Company.
Furthermore, except as set forth in this Agreement and as set forth on Schedule 2.1(c) hereto, there are no contracts, commitments, understandings, or arrangements by which the Company is or may become bound to issue additional shares of the
capital stock of the Company or options, securities or rights convertible into shares of capital stock of the Company. Except for customary transfer restrictions contained in agreements entered into by the Company in order to sell restricted
securities or as provided on Schedule 2.1(c) hereto, the Company is not a party to or bound by any agreement or understanding granting registration or anti-dilution rights to any person with respect to any of its equity or debt securities.
Except as set forth on Schedule 2.1(c),

the Company is not a party to, and it has no knowledge of, any agreement or understanding restricting the voting or transfer of any shares of the capital
stock of the Company.

(d) Issuance of Securities. The Shares and the Warrants to be issued at the Closing have been
duly authorized by all necessary corporate action and, when paid for and issued in accordance with the terms hereof and the Warrants, respectively, the Shares and the Warrant Shares will be validly issued, fully paid and nonassessable and free and
clear of all liens, encumbrances and rights of refusal of any kind and the holders shall be entitled to all rights accorded to a holder of Common Stock.

(e) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby do not and will not
(i) violate any provision of the Companys Certificate of Incorporation (the Certificate) or Bylaws (the Bylaws), each as amended to date, or any Subsidiarys comparable charter documents,
(ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, mortgage,

or (iii) result in a violation of any federal, state, local or foreign statute, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to the Company or any of its Subsidiaries or by
which any property or asset of the Company or any of its Subsidiaries are bound or affected, except, in all cases, other than violations pursuant to clauses (i) or (iii) (with respect to federal and state securities laws) above, except,
for such conflicts, defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect. The business of the Company and its Subsidiaries is not being

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

upon the representations herein of the Purchasers, the Company has complied and will comply with all applicable federal and state securities laws in connection with the offer, issuance and sale of the Securities hereunder. Neither the Company nor
anyone acting on its behalf, directly or indirectly, has or will sell, offer to sell or solicit offers to buy any of the Securities or similar securities to, or solicit offers with respect thereto from, or enter into any negotiations relating

public utility company as such terms are defined in the Public Utility Holding Company Act of 1935, as amended. The Company is not, and as a result of and immediately upon the Closing will not be, an investment company or a
company controlled by an investment company, within the meaning of the Investment Company Act of 1940, as amended.

(bb) ERISA. No liability to the Pension Benefit Guaranty Corporation has been incurred with respect to any Plan by the Company or any of its Subsidiaries which is or would be materially adverse to the Company
and its Subsidiaries. The execution and delivery of this Agreement and the issuance and sale of the Shares and the Warrants will not involve any transaction which is subject to the prohibitions of Section 406 of ERISA or in connection with
which a tax could be imposed pursuant to Section 4975 of the Internal Revenue Code of 1986, as amended, provided that, if any of the Purchasers, or any person or entity that owns a beneficial interest in any of the Purchasers, is an
employee pension benefit plan (within the meaning of Section 3(2) of ERISA) with respect to which the Company is a party in interest (within the meaning of Section 3(14) of ERISA), the requirements of Sections

(dd) Independent Nature of Purchasers. The Company acknowledges that the obligations of each Purchaser under the Transaction
Documents are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under the Transaction Documents. The decision of each
Purchaser to purchase Securities pursuant to this Agreement has been made by



12



---

such Purchaser independently of any other purchase and independently of any information, materials, statements or opinions as to the business, affairs,
operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries which may have made or given by any other Purchaser or by any agent or employee of any other
Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any Purchaser (or any other person) relating to or arising from any such information, materials, statements or opinions. The Company further acknowledges that
nothing contained herein, or in any Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently protect and
enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for
such purpose. For reasons of administrative convenience only, the Transaction Documents have been prepared by counsel for the placement agent. Such counsel does not represent the Purchasers and the Purchasers have retained their own individual
counsel with respect to the transactions contemplated hereby. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do
so by the Purchasers. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption that the Purchasers are in any way acting in concert or as a group with respect to the Transaction Documents
or the transactions contemplated hereby or thereby.

(ee) No Integrated Offering. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security under circumstances that would cause the offering of the Securities pursuant to
this Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act which would prevent the Company from selling the Securities pursuant to Regulation D and Rule 506 thereof under the Securities Act, or any
applicable exchange-related stockholder approval provisions, nor will the Company or any of its affiliates or subsidiaries take any action or steps that would cause the offering of the Securities to be integrated with other offerings if such other
offering, if integrated, would cause the offer and sale of the Securities not to be exempt from registration pursuant to Regulation D and Rule 506 thereof under the Securities Act. The Company does not have any registration statement pending before
the Commission or currently under the Commissions review and except as set forth on Schedule 2.1(ee) hereto, since September 1, 2005, the Company has not offered or sold any of its equity securities or debt securities convertible

Section 2.2 Representations and Warranties of the Purchasers.

Each of the Purchasers hereby represents and warrants to the Company with respect solely to itself and not with respect to any other Purchaser as follows
as of the date hereof and as of the Closing Date:

(a) Organization and Standing of the Purchasers. If the Purchaser
is an entity, such Purchaser is a corporation, limited liability company or partnership duly incorporated or organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization.

(b) Authorization and Power. Each Purchaser has the requisite power and authority to enter into and perform the Transaction
Documents and to purchase the Securities being sold to it hereunder. The execution, delivery and performance of the Transaction Documents by each Purchaser and the consummation by it of the transactions contemplated hereby have been duly authorized
by all necessary corporate or partnership action, and no further consent or authorization of such Purchaser or its Board of Directors, stockholders, or partners, as the case may be, is required. When executed and delivered by the Purchasers, the
other Transaction Documents shall constitute valid and binding obligations of each Purchaser enforceable against such Purchaser in accordance with their terms, except as such enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditors rights and remedies or by other equitable principles of general application.

(c) No Conflict. The execution, delivery and performance of the Transaction Documents by the Purchaser and the consummation by
the Purchaser of the transactions contemplated thereby and hereby do not and will not (i) violate any provision of the Purchasers charter or organizational documents, (ii) conflict with, or constitute a default (or an event which
with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, mortgage, deed of trust, indenture, note, bond, license, lease agreement,
instrument or obligation to which the Purchaser is a party or by which the Purchasers respective properties or assets are bound, or (iii) result in a violation of any federal, state, local or foreign statute, rule, regulation, order,
judgment or decree (including federal and state securities laws and regulations) applicable to the Purchaser or by which any property or asset of the Purchaser are bound or affected, except, in all cases, other than violations pursuant to clauses
(i) or (iii) (with respect to federal and state securities laws) above, except, for such conflicts, defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, materially
and adversely affect the Purchasers ability to perform its obligations under the Transaction Documents.

(d)
Acquisition for Investment. Each Purchaser is purchasing the Shares and Warrants solely for its own account for the purpose of investment and not with a view to or for sale in connection with distribution. Each Purchaser does not have a
present intention to sell any of the Shares or Warrants, nor a present arrangement (whether or not legally binding) or intention to effect any distribution of any of the Shares or Warrants to or through any person or entity; provided,
however, that by making the representations herein, such Purchaser does not agree to hold the Shares or the Warrants for any minimum or other specific term and reserves the right to dispose of the Shares or the Warrants at any time in
accordance with Federal and state

securities laws applicable to such disposition. Each Purchaser acknowledges that it (i) has such knowledge and experience in financial and business
matters such that Purchaser is capable of evaluating the merits and risks of Purchasers investment in the Company, (ii) is able to bear the financial risks associated with an investment in the Securities and (iii) has been given full
access to such records of the Company and the Subsidiaries and to the officers of the Company and the Subsidiaries as it has deemed necessary or appropriate to conduct its due diligence investigation.

(e) Rule 144. Each Purchaser understands that the Securities must be held indefinitely unless such Shares are registered under the
Securities Act or an exemption from registration is available. Each Purchaser acknowledges that such person is familiar with Rule 144 of the rules and regulations of the Commission, as amended, promulgated pursuant to the Securities Act
(Rule 144), and that such Purchaser has been advised that Rule 144 permits resales only under certain circumstances. Each Purchaser understands that to the extent that Rule 144 is not available, such Purchaser will be unable to
sell any Securities without either registration under the Securities Act or the existence of another exemption from such registration requirement.

(f) General. Each Purchaser understands that the Securities are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities laws and the
Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of
such Purchaser to acquire the Securities. Each Purchaser understands that no United States federal or state agency or any government or governmental agency has passed upon or made any recommendation or endorsement of the Securities.

(g) No General Solicitation. Each Purchaser acknowledges that the Securities were not offered to such Purchaser by means of any
form of general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (i) any advertisement, article, notice or other communication published in any newspaper, magazine, or similar
media, or broadcast over television or radio, or (ii) any seminar or meeting to which such Purchaser was invited by any of the foregoing means of communications.

(h) Accredited Investor. Each Purchaser is an accredited investor (as defined in Rule 501 of Regulation D), and such
Purchaser has such experience in business and financial matters that it is capable of evaluating the merits and risks of an investment in the Securities. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the
Exchange Act and such Purchaser is not a broker-dealer. Each Purchaser acknowledges that an investment in the Securities is speculative and involves a high degree of risk. Each Purchaser has completed or caused to be completed the Investor
Questionnaire Certification attached hereto as Exhibit D certifying as to its status as an accredited investor and understands that the Company is relying upon the truth and accuracy of the Purchaser set forth therein to determine
the suitability of such Purchaser to acquire the Securities.

(i) Certain Fees. The Purchasers have not employed any
broker or finder or incurred any liability for any brokerage or investment banking fees, commissions, finders



15



---

structuring fees, financial advisory fees or other similar fees in connection with the Transaction Documents.

(j) Independent Investment. Except as may be disclosed in any filings with the Commission by the Purchasers under Section 13
and/or Section 16 of the Exchange Act, no Purchaser has agreed to act with any other Purchaser for the purpose of acquiring, holding, voting or disposing of the Securities purchased hereunder for purposes of Section 13(d) under the
Exchange Act, and each Purchaser is acting independently with respect to its investment in the Securities.

(k) Patriot
Act. If the Purchaser is an individual, the Purchaser certifies that he or she is not nor to his or her knowledge has been designated, a suspected terrorist as defined in Executive Order 13224. If the Purchaser is a corporation,
trust, partnership, limited liability company or other organization, the Purchaser certifies that, to the best of Purchasers knowledge, the Purchaser has not been designated, and is not owned or controlled, by a suspected terrorist
as defined in Executive Order 13224. The Purchaser hereby acknowledges that the Company seeks to comply with all applicable laws concerning money laundering and related activities. In furtherance of those efforts, the Purchaser hereby represents,
warrants and agrees that to its knowledge: (i) none of the cash or property that the Purchaser will pay or will contribute to the Company has been or shall be derived from, or related to, any activity that is deemed criminal under United States
law; and (ii) no contribution or payment by the Purchaser to the Company, to the extent that they are within the Purchasers control shall cause the Company to be in violation of the United States Bank Secrecy Act, the United States
International Money Laundering Control Act of 1986 or the United States International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001. The Purchaser shall promptly notify the Company if any of these representations ceases to be
true and accurate regarding the Purchaser. If the Company reasonably believes that the Purchaser has breached the foregoing representations, then the Purchaser agrees to provide the Company any additional information regarding the Purchaser that the
Company deems necessary to ensure compliance with all applicable laws concerning money laundering and similar activities. In the event that the Company is requested or required (by deposition, interrogatory, request for documents, subpoena, civil
investigative demand or similar legal, judiciary or regulatory process or as otherwise required by applicable law or regulation) to disclose any confidential information about a Purchaser, the Company shall (A) provide the Purchaser with prompt
prior written notice of such request or requirement and (B) cooperate with the Purchaser so that the Purchaser may seek a protective order or other appropriate remedy. In the event that such protective order or other remedy is not obtained, the
Company and their respective representatives shall disclose only that portion of the confidential information that such person is advised by legal counsel in writing is legally required to be disclosed, and provided that the Company uses
reasonable efforts to obtain reliable assurance that confidential treatment will be accorded any confidential information so disclosed.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE SECURITIES) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
SECURITIES ACT) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR FIBERNET TELECOM GROUP, INC. SHALL HAVE
RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

The Company agrees to reissue certificates representing any of the Shares and the Warrant Shares, without the legend set forth above if at such time,
prior to making any transfer of any such Shares or Warrant Shares, such holder thereof shall give written notice to the Company describing the manner and terms of such transfer and removal as the Company may reasonably request. Such proposed
transfer and removal will not be effected until: (a) the Company has notified such holder that either (i) in the opinion of Company counsel, the registration of the Shares or Warrant Shares under the Securities Act is not required in
connection with such proposed transfer; or (ii) a registration statement under the Securities Act covering such proposed disposition has been filed by the Company with the Commission and has become effective under the Securities Act; and
(b) the Company has notified such holder that either: (i) in the opinion of Company counsel, the registration or qualification under the securities or blue sky laws of any state is not required in connection with such proposed



22



---

disposition, or (ii) compliance with applicable state securities or blue sky laws has been effected. The Company will respond to any such
notice from a holder within five (5) Business Days. In the case of any proposed transfer under this Section 5.1, the Company will use reasonable efforts to comply with any such applicable state securities or blue sky laws, but
shall in no event be required, (x) to qualify to do business in any state where it is not then qualified, (y) to take any action that would subject it to tax or to the general service of process in any state where it is not then subject,
or (z) to comply with state securities or blue sky laws of any state for which registration by coordination is unavailable to the Company. The restrictions on transfer contained in this Section 5.1 shall be in addition to, and
not by way of limitation of, any other restrictions on transfer contained in any other section of this Agreement. Whenever a certificate representing the Shares or Warrant Shares is required to be issued to a Purchaser without a legend, in lieu of
delivering physical certificates representing the Shares or Warrant Shares, provided the Companys transfer agent is participating in the Depository Trust Company (DTC) Fast Automated Securities Transfer program, the
Company shall use its best efforts to cause its transfer agent to electronically transmit the Shares or Warrant Shares to a Purchaser by crediting the account of such Purchasers Prime Broker with DTC through its Deposit Withdrawal Agent
Commission (DWAC) system (to the extent not inconsistent with any provisions of this Agreement).

ARTICLE VI

Indemnification

Section 6.1
General Indemnity.

(a) The Company agrees to indemnify and hold harmless each Purchaser (and its respective directors, officers,
affiliates, agents, successors and assigns) from and against any and all losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys fees, charges and disbursements)
(Losses) incurred by each Purchaser as a result of any inaccuracy in or breach of the representations, warranties or covenants made by the Company herein. The Purchasers severally but not jointly agree to indemnify and hold
harmless the Company and its directors, officers, affiliates, agents, successors and assigns from and against any and all Losses incurred by the Company as result of any inaccuracy in or breach of the representations, warranties or covenants made by
the Purchasers herein.

(b) Notwithstanding the foregoing, neither the Company nor the Purchasers shall be entitled to any indemnification
under this Article VI unless and until all Losses of the Company or the Purchasers, as applicable, in the aggregate, are in excess of $50,000 and the Company, or the Purchasers, as applicable, shall then only be liable for Losses in excess of such
amount. The maximum aggregate liability of the Company pursuant to its indemnification obligations under this Article VI shall not exceed the aggregate Purchase Price received hereunder, and the maximum aggregate liability of each Purchaser pursuant
to its indemnification obligations shall not exceed the portion of the Purchase Price paid by such Purchaser hereunder.



23



---

Section 6.2 Indemnification Procedure.

Any party entitled to indemnification under this Article VI (an indemnified party) will give written notice to the indemnifying party of any
matters giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Article VI
except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the
indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnifying party a conflict of interest between it and the indemnified party exists with respect to such action, proceeding or claim (in which
case the indemnifying party shall be responsible for the reasonable fees and expenses of one separate counsel for the indemnified parties), to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. In the event
that the indemnifying party advises an indemnified party that it will not contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its
election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or
otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified partys costs and
expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall cooperate fully with the indemnifying party in connection with
any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party
shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall
be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent.
Notwithstanding anything in this Article VI to the contrary, the indemnifying party shall not, without the indemnified partys prior written consent, settle or compromise any claim or consent to entry of any judgment in respect thereof which
imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The
indemnification required by this Article VI shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the
indemnified party irrevocably agrees to refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to
(a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law.

Section 7.2 Specific Performance; Consent to Jurisdiction; Venue.

(a) The Company and the Purchasers
acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement or the other Transaction Documents were not performed in accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent or cure breaches of the provisions of this Agreement or the other Transaction Documents and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be entitled by law or equity.

(b) The parties
agree that venue for any dispute arising under this Agreement will lie exclusively in the state or federal courts located in New York County, New York, and the parties irrevocably waive any right to raise forum non conveniens or any other
argument that New York is not the proper venue. The parties irrevocably consent to personal jurisdiction in the state and federal courts of the state of New York. The Company and each Purchaser consent to process being served in any such suit,
action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing in this
Section 7.2 shall affect or limit any right to serve process in any other manner permitted by law. The Company and the Purchasers hereby agree that the prevailing party in any suit, action or proceeding arising out of or relating to the
Securities, this Agreement or the Registration Rights Agreement, shall be entitled to reimbursement for reasonable legal fees from the non-prevailing party.

Company and the consummation by it of the transactions contemplated thereby have been duly and validly authorized by all necessary corporate action and no further consent or authorization of the Company or its Board of Directors is required. Each of
the Transaction Documents has been duly executed and delivered and each of the Transaction Documents constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its respective terms. The

any Material Agreement to which the Company is a party and which is known to us, (c) create or impose a lien, charge or encumbrance on any property of the Company under any Material Agreement known to us to which the Company is a party or by
which the Company is bound or by which any of its respective properties or assets are bound, or (d) result in a violation of any federal or state statute, rule or regulation (including federal and state securities laws and regulations)
applicable to the Company or by which any property or asset of the Company is bound or affected, except, in all cases other than violations pursuant to clause (a) above, for such conflicts, default, terminations, amendments, acceleration,
cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect.

5. No consent, approval or
