3.1 Corporate Status. Each of the Company and its Subsidiaries (a) is duly organized, validly existing and in good standing under the laws of
the jurisdiction of its organization and has the corporate or limited liability company, as applicable, power and authority to own its property and assets and to transact the business in which it is engaged and presently proposes to engage and (b)
has duly qualified to do business and is in good standing in each jurisdiction where it is required to be so qualified and where the failure to be so qualified would reasonably be expected to have a Material Adverse Effect. Neither the Company nor
any of its Subsidiaries is currently in violation of any of the provisions of its Certificate of Incorporation (or other charter document) or By-laws, each as amended to date. 
  
 3.2 Corporate Power and Authority. All corporate action on the part of the Company, its officers, directors and
shareholders necessary for the authorization, execution, delivery and performance of this Agreement and the Transaction Documents and the consummation of the transactions contemplated herein and therein has been taken. When executed and delivered by
the Company, this Agreement and each of the Transaction Documents shall constitute the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such may be limited by bankruptcy,
insolvency, reorganization or other laws affecting creditors’ rights generally and by general equitable principles. The Company has all requisite corporate power and authority to enter into this Agreement and the Transaction Documents and to
carry out and perform its obligations under the terms hereof and thereof. 
  
 3.3 No Violation. Neither the execution, delivery and performance by the Company of this Agreement and the Transaction Documents nor compliance with the terms and provisions hereof and thereof (a) will

bound or to which it may be subject or result in the acceleration of any material obligation of the Company, or (c) will violate any provision of the Certificate of Incorporation or by-laws of the Company, each as amended to date. 
  
 3.4 Capitalization. Exhibit 3.4 sets forth the number of authorized,
issued and outstanding shares of capital stock of the Company, and outstanding warrants and options to purchase capital stock of the Company (a) as of the date hereof, (b) as of the date hereof pro forma to give effect to the Teligent Acquisition
and (c) as of the date hereof pro forma to give effect to the sale of the Shares and Warrants hereunder. As of the date hereof, the authorized capital stock of the Company consists of 100,000,000 shares of Common Stock, of which 21,288,016 shares

 outstanding options, warrants, rights (including conversion or preemptive rights) or any agreement for the purchase or
acquisition from the Company or any Subsidiary of any shares of the Company’s capital stock or voting agreements with respect to equity of the Company. All shares of the capital stock of the Company subject to issuance as aforesaid, upon
issuance on the terms and conditions specified in the instruments pursuant to which they are issuable, shall be duly authorized, validly issued, fully paid and nonassessable. There are no obligations, contingent or otherwise, of the Company or any
Subsidiary to repurchase, redeem or otherwise acquire any shares of Common Stock or other equity securities of the Company or to provide funds to or make any investment (in the form of a loan, capital contribution, guaranty or otherwise) in any
other entity. The sale of the Shares and the issuance of the Warrants under this Agreement, and the issuance of any Warrant Shares upon exercise of the Warrants in their current form, will not result in the Company being obligated to issue, sell or
purchase, pursuant to any existing pre-emptive, anti-dilution, redemption or other right of third parties, shares of Common Stock or other securities to or from any Person (other than the Purchasers), and will not result in a right of any holder of
convertible or contingent securities issued by the Company to adjust the exercise, conversion, exchange or reset price under such securities, including, in any such case, pursuant to any “poison pill” or shareholders rights plan. None of
the outstanding shares of capital stock of the Company were issued in violation of the Securities Act or any state securities laws. 
  
 3.5 Valid Issuance of the Shares. The Shares, the Warrants and the Warrant Shares have been duly authorized, and the Shares and the Warrant Shares,

of the stockholders of the Company or any other Person, and (c) the applicable Purchaser (with respect to the Shares) and the applicable Holder (as defined in the Warrant) will obtain sole record and beneficial ownership of such Shares and Warrant
Shares (as applicable) and take good marketable title thereto, free and clear of any Liens (defined for purposes hereof without regard to the carve-outs set forth in clauses (a) through (c) of the definition of Lien), claims, charges, taxes, options
or transfer restrictions of any kind which are imposed by the Company, or arise as a result of the Company’s action or omission, other than those transfer restrictions explicitly set forth in this Agreement and in the Warrants. The Company has
reserved from its duly authorized capital stock the number of shares of Common Stock issuable upon execution of this Agreement and upon exercise in full of the Warrants (assuming the Warrants vest in full).

Schedules, no actions, suits, claims, investigations or proceedings are pending or, to the Company’s knowledge, threatened that would reasonably be expected to have, individually or in the aggregate (a) a Material Adverse Effect or (b) an
adverse effect on the rights or remedies of the Purchasers or on the ability of the Company or its Subsidiaries to perform their respective obligations under this Agreement or the Transaction Documents. Neither the Company nor any Subsidiary is a
party to or named in or subject to any order, writ, injunction, judgment or decree of any court or Governmental Authority. There is no action, suit, claim, proceeding or investigation by the Company or any Subsidiary currently pending or that the
Company or any Subsidiary currently intends to initiate.

this Agreement and the Transaction Documents, the consummation of 
  

 -6- 

 the transactions contemplated herein and therein, and the issuance of the Shares and the Warrants and, upon exercise of
the Warrants, the Warrant Shares, do not require the consent or approval of the stockholders of the Company or any other Person. 
  
 3.8 Contracts. All material agreements to which the Company is a party or to which the property or assets of the Company are subject are included
as part of or specifically identified in the SEC Reports to the extent required by the rules and regulations of the SEC as in effect at the time of filing of such SEC Reports. All such material agreements required to be filed as exhibits to the SEC
Reports are legal, valid and binding obligations of the Company in accordance with their respective terms and, to the knowledge of the Company, the other parties thereto, except in any case as may be limited by bankruptcy, insolvency, reorganization
or other laws affecting creditors’ rights generally and by general equitable principles. The Company and its Subsidiaries are not, nor to their knowledge is any counterparty, in violation of or default under, any material agreement.

regarding any taxes relating to the Company or any of its Subsidiaries which would reasonably be expected to have a Material Adverse Effect. As of the Closing Date, neither the Company nor any of its Subsidiaries has entered into an agreement or

 3.17 Properties. The Company and each of its
Subsidiaries owns its properties and assets, including all such properties reflected in their balance sheets included in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2004, free and clear of all Liens, other

 3.18 Labor Relations. The Company and its Subsidiaries are not engaged
in any unfair labor practice. No unfair labor practice complaint is pending against the Company or any of its Subsidiaries or, to the best of its knowledge, threatened against it or any of its Subsidiaries, before the National Labor Relations Board
or similar foreign labor relations authority, and no grievance or arbitration proceeding arising out of or under any collective bargaining agreement is so pending against the Company or any of its Subsidiaries, or, to the best of its knowledge,
threatened against it or any of its Subsidiaries. No strike, labor dispute, slowdown or stoppage is pending against the Company or any of its Subsidiaries or, to the best of its knowledge, threatened against the Company or any of it Subsidiaries. No

employment contract, patent disclosure agreement, or other contract or agreement relating to the relationship of any such employee with the Company or any Subsidiary, or any other party because of the nature of the business presently conducted or
presently proposed to be conducted by the Company and its Subsidiaries. The Company is not aware that any officer or key employee, or that any group of key employees, intends to terminate their employment with the Company or any Subsidiary, nor does
the Company or any Subsidiary have a present intention to terminate the employment of any of the foregoing. Subject to general principles related to wrongful termination of employees, the employment of each officer and employee of the Company and
its Subsidiaries is terminable at the will of the Company or the applicable Subsidiary. 
  
 3.19 Regulatory Matters. 
  
 (a) Authorizations. The Company holds all Federal Communications Commission (“FCC”), state public utility commission (“PUC”) and foreign regulatory authority permits, licenses, certificates,
registrations and other similar authorizations necessary or appropriate for the conduct of its business (collectively, the “Authorizations”), the lack of which would, individually or in the aggregate, reasonably be expected to have
a Material Adverse Effect. The Company and its Subsidiaries have maintained and kept in force and effect, and have applied in a timely manner for renewal of all such Authorizations. Except as disclosed in Section 3.19(a) of the Disclosure Schedules,
the Company and its Subsidiaries are in compliance with all such Authorizations and any terms and conditions thereto except such non-compliance as would not, individually or in the aggregate, have a Material Adverse Effect. Except as disclosed in
Section 3.19(a) of the Disclosure Schedules, each Authorization which is material to the business of the Company is valid and in full force and effect, and the Company and its Subsidiaries have not received notice from the FCC, any PUC, or any
foreign regulatory authority of its intention to revoke, suspend, condition or fail to renew any such Authorization, which would, individually or in the aggregate, have a Material Adverse Effect. Except as disclosed in Section 3.19(a) of the
Disclosure Schedules, no event has occurred or facts and circumstances exist, which allows or would reasonably be 
  

 -9- 

 expected to allow, or which after notice or lapse of time would allow or would reasonably be expected to allow,
revocation, suspension, non-renewal or termination or result in any other material impairment of the Company’s or its Subsidiaries’ rights under any of its Authorizations to the extent that such revocation, termination or impairment would
have a Material Adverse Effect. 
  
 (b) Compliance with
Law. Except as disclosed in Section 3.19(a) of the Disclosure Schedules, the conduct of the Company’s business complies with all applicable U.S., state, local and foreign laws (including, without limitation, the Communications Act of 1934,
as amended, and the Communications Assistance for Law Enforcement Act), ordinances, rules, regulations, and orders (including, without limitation, those issued by the FCC, any PUC or any foreign regulatory authority), except where the failure to so
comply would not reasonably be expected to have a Material Adverse Effect. 
  
 3.20 Permits. The Company and its Subsidiaries have all franchises, permits, licenses and any similar authority (the “Permits”) necessary for the conduct of their business as now being
conducted by them, the lack of which could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. As of the date hereof, no suspension or cancellation of any of the Permits is pending or, to the knowledge of the
Company, threatened which could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company believes it can obtain, without undue burden or expense, any similar authority for the conduct of its business
as presently proposed to be conducted. The Company and its Subsidiaries are not in default under any of such franchises, permits, licenses or other similar authorities. 
  
 3.21 ERISA. Neither the Company, any Subsidiary of the Company nor any ERISA Affiliate maintains or contributes to
any Plan other than those listed in Section 3.21 of the Disclosure Schedules. 
  
 (a) Compliance with ERISA. The Company and each ERISA Affiliate is in compliance with ERISA, except for such failures to comply that, in the aggregate for all such failures, would not reasonably be expected to
have a Material Adverse Effect and no contributions required to be made by the Company or any ERISA Affiliate to any pension plan are overdue. 
  
 (b) PBGC. No liability to the PBGC has been or is expected to be incurred by the Company or any ERISA Affiliate with respect to any pension plan
that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect. No circumstance exists that constitutes grounds under section 4042 of ERISA entitling the PBGC to institute proceedings to terminate, or appoint
a trustee to administer, any pension plan or trust created thereunder, nor has the PBGC instituted any such proceeding. 
  
 (c) Multiemployer Plans. Neither the Company nor any ERISA Affiliate has incurred or presently expects to incur any withdrawal liability under
Title IV of ERISA with respect to any multiemployer plan except for such withdrawal liability that, in the aggregate of all such liabilities, would not reasonably be expected to have a Material Adverse Effect. There have been no “reportable
events” (as such term is defined in section 4043 of ERISA) with respect to any multiemployer plan that could result in the termination of such multiemployer plan and give rise to a liability of the Company or any ERISA Affiliate in respect
thereof except for such “reportable events” that, in the aggregate for all such “reportable events,” would not reasonably be expected to have a Material Adverse Effect. Neither the Company nor any Subsidiary has incurred or does
it expect to incur liability under Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the
Company would have any liability that is intended to be qualified under Section 401(a) of the Code has been determined by the Internal Revenue Service to be so qualified and nothing has occurred, whether by action or by failure to act, which could
reasonably be expected to cause the loss of such qualification.

Registration Statements or other SEC Reports, there are no material liabilities of the Company or any Subsidiary, other than liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2004 or which in
the aggregate would not reasonably be expected to result in a Material Adverse Effect. 
  
 3.23 Insurance. The Company maintains insurance of the types and in the amounts and covering such risks as is prudent and adequate for its business as currently conducted and for the value of its properties as
is customary for companies engaged in similar lines of business in similar industries, all of which insurance is in full force and effect. Neither the Company nor any Subsidiary has (i) received notice from any insurer or agent of such insurer that
capital improvements or other expenditures are required or necessary to be made in order to continue such insurance or (ii) 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 at reasonable cost from similar insurers as may be necessary to continue its business. 
  
 3.24 Accounts Receivable. The accounts and notes receivable of the Company and its Subsidiaries reflected on the balance sheet included in the

contemplated by this Agreement. 
  
 3.26 Leases.
Each of the Company and the Subsidiaries has complied with all material obligations under all leases for real property to which it is a party as a lessee. All leases relating to the leasehold estates of each of the Company and the Subsidiaries
necessary for the conduct of the business of such Person are, with respect to the Company, valid and enforceable, and, to the knowledge of the Company, are, valid and enforceable with respect to the lessor, and each of the Company and the
Subsidiaries that is the lessee in respect thereof currently enjoys peaceful and undisturbed possession of the premises subject thereto.  
  
 3.27 Intellectual Property. Except as set forth in Section 3.27 of the Disclosure Schedules, each of the Company and the Subsidiaries owns,
possesses or has the right to use all of the patents, trademarks, service marks, trade names, copyrights, franchises and licenses, and rights with respect thereto (collectively, “Intellectual Property”), necessary for the present
conduct of its business and as such business is proposed to be conducted, without any infringement of the rights of others. There are no outstanding options, licenses, or agreements of any kind relating to the Company’s and/or its
Subsidiaries’ Intellectual Property with the exception of agreements for the sale or license of the Company’s products or services in the ordinary course of business. The Company has not received any communications alleging that the

 (i) notice from any Governmental Authority by which any of its currently or previously owned or leased properties has been
identified in any manner by any Governmental Authority as a hazardous substance disposal or removal site, “Super Fund” clean-up site, or candidate for removal or closure pursuant to any Environmental Protection Law, 
  
 (ii) notice of any Lien arising under or in connection with any
Environmental Protection Law that has attached to any revenues of, or to, any of its currently or previously owned or leased properties, or 
  
 (iii) communication, written or oral, from any Governmental Authority concerning any action or omission in connection with its currently or previously
owned or leased properties resulting in the release of any hazardous substance resulting in any violation of any Environmental Protection Law, 
  
 in each case where the effect of which, in the aggregate for all such notices and communications, would reasonably be expected to have a Material Adverse
Effect. 
  
 3.29 Registration Rights. Except as set forth
on Section 3.29 of the Disclosure Schedules, the Company is not currently subject to any agreement providing any Person any rights (including piggyback registration rights) to have any securities of the Company registered with the SEC or registered
or qualified with any other Governmental Authority. Currently, no Person has, with respect to the Company, and the Company will not grant to any Person any registration rights (including demand and “piggyback” registration rights)

 -12- 

 the Disclosure Schedules, there are no agreements, understandings or proposed transactions between the Company or any
Subsidiary, on the one hand, and any of its officers, affiliates or directors, or any of their affiliates, on the other hand. 
  
 3.31 Internal Accounting Controls. The Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that
(i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with United States generally accepted
accounting principles and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorizations, and (iv) the recorded accountability for assets is compared with the

Rule l5d-14 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to the Company and its Subsidiaries is made known to the Company’s principal executive officer and its

internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses; the principal executive officer and principal financial officer of the Company have made all certifications required by the
Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and any related rules and regulations promulgated by the SEC, and the statements contained in any such certification are complete and correct; and the Company and its
Subsidiaries are otherwise in compliance with all applicable provisions of the Sarbanes-Oxley Act that are effective.

as provided in this Agreement and the Warrants, is and is intended to be (a) exempt from the registration requirements of the Securities Act pursuant to one or more of Sections 3(b) and 4(2) thereof and Regulation D promulgated thereunder, and (b)

 3.33 No Integrated Offering.
Neither the Company, nor any Affiliate of the Company, 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 or issuance of the Shares, the Warrants or any Warrant Shares pursuant to this Agreement and the Transaction Documents to be integrated with prior offerings by the Company for purposes of the Securities Act which would cause the
exemptions from SEC registration upon which the Company is relying for the offering or issuance of the Shares, the Warrants or any Warrant Shares pursuant to this Agreement to be unavailable, or would cause any applicable state securities laws
exemptions or any applicable stockholder approval provisions exemptions, including, without limitation, under the rules and regulations of any national securities exchange or automated quotation system on which any of the 
  

 -13- 

 securities of the Company are listed or designated to be unavailable, nor will the Company take any action or steps that
would cause the offering or issuance of the Shares, the Warrants or any Warrant Shares pursuant to this Agreement and the Transaction Documents to be integrated with other offerings. 
  
 3.34 Section 203 of the DGCL. Each Purchaser is not an “interested stockholder” (as defined in Section 203

restrictions on “business combinations” (as defined in Section 203 of the DGCL) set forth in Section 203 of the DGCL do not apply to the transactions contemplated hereby. The Board of Directors of the Company has approved the issuance to

known and contingent liabilities) as they mature; (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business for the current fiscal year as now conducted and as proposed to be conducted, including its
capital needs taking into account the particular capital requirements of the business conducted by the Company, projected capital requirements and capital availability thereof; and (iii) the current cash flow of the Company, together with the
proceeds the Company would receive were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debts when such amounts are required to be paid.
The Company has no present intention to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). 
  
 3.37 Disclosure. Neither this Agreement, the Registration Rights
Agreement, the Warrants, the Offering Memorandum, nor any other statements or certificates made or delivered in connection herewith or therewith, when taken as a whole, contains any untrue statement of a material fact or omits to state a material

to the Company as follows:

enforceable against such Purchaser in accordance with its terms, except as such may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and by general equitable principles. Such Purchaser has

is exempt from such registration. Such Purchaser understands that the exemptions from registration afforded by Rule 144 (the provisions of which are known to it) promulgated under the Securities Act depend on the satisfaction of various conditions,

registration statement under the Securities Act; (ii) to an Affiliate (so long as such Affiliate agrees to certify that it is an “accredited investor” as defined in Rule 501(a) under the Securities Act and to be bound by the terms and
provisions of this Agreement as if, and to the fullest extent as, such Purchaser) or to partners or members in a pro rata distribution; or (iii) pursuant to an available exemption from registration under the Securities Act (including sales permitted
pursuant to Rule 144) and applicable state securities laws. Any transfer or purported transfer of the Shares in violation of this Section 6.1 shall be void. The Company shall not register any transfer of the Shares in violation of this Section 6.1.
The Company may, and may instruct any transfer agent for the Company, to place such stop transfer orders as may be required on the transfer books of the Company in order to ensure compliance with the provisions of this Section 6.1. 
  
 6.2 Legends. 
  
 (a) To the extent applicable, each certificate or other document evidencing
the Shares, the Warrants and any Warrant Shares shall be endorsed with the legend set forth below, and each Purchaser covenants that, except to the extent such restrictions are waived by the Company, it shall not transfer the shares represented by
any such certificate without complying with the restrictions on transfer described in this Agreement and the legends endorsed on such certificate: 
  
 “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED OR SOLD IN
THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, REGISTRATION UNDER SAID ACT.” 
  
 (b) The legend set forth in Section 6.2(a) shall be removed from the certificates evidencing the Shares, Warrants and any
Warrant Shares, (i) following any sale of such Shares, Warrants or Warrant Shares pursuant to Rule 144 or any effective registration statement, or (ii) if such Shares, Warrants or Warrant Shares are eligible for sale under Rule 144(k) (and the
holder of such Shares, Warrants or Warrant Shares has submitted a written request for removal of the legend indicating that the holder has complied with the applicable provisions of Rule 144), or (iii) if such legend is not required under applicable
requirements of the Securities Act (including judicial interpretations and pronouncements issued by the Staff of the SEC) (and the holder of such Shares, Warrants or Warrant Shares has submitted a written request for removal of the legend indicating
that the holder has complied with such judicial interpretation or pronouncement). Subject to receipt of appropriate certifications, the Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent promptly upon the
occurrence of any of the events in clauses (i), (ii) or (iii) above to effect the removal of the legend on 
  

 -18- 

 certificates evidencing the Shares or any Warrant Shares and shall also cause its counsel to issue a “blanket”
legal opinion to the Company’s transfer agent promptly after the effective date of any registration statement covering the resale of the Shares or any Warrant Shares (provided that there is an effective registration statement covering the
resale of the Shares or any Warrant Shares, as the case may be), if required by the Company’s transfer agent, to allow sales without restriction pursuant to an effective registration statement. The Company agrees that at such time as such
legend is no longer required under this Section 6.2(b), it will, no later than three (3) business days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing the Shares, Warrants or
any Warrant Shares issued with a restrictive legend, deliver or cause to be delivered to such Purchaser a certificate representing such Shares, Warrants or Warrant Shares that is free from all restrictive and other legends; provided that in
the case of removal of the legend for reasons set forth in clause (ii) above, the holder of such Shares, Warrants or Warrant Shares has submitted a written request for removal of the legend indicating that the holder has complied with the applicable
provisions of Rule 144. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section 6. 
  
 6.3 Publicity. Except to the extent required by applicable laws,
rules, regulations or stock exchange requirements, the Company, the Subsidiaries and their Affiliates shall not, without the written consent of the Majority Purchasers, make any public announcement or issue any press release with respect to the
transactions contemplated by this Agreement; provided that the Company, each Subsidiary and their respective Affiliates shall not, without the prior written consent of the Purchaser, disclose or publish the name of such Purchaser in any such press
release or public announcement. Except to the extent required by applicable laws, rules, regulations or stock exchange requirements, the Purchasers and their Affiliates shall not, without the written consent of the Company make any public
announcement or issue any press release with respect to the transactions contemplated by this Agreement. In no event will either (i) the Company, the Subsidiaries or any of their Affiliates or (ii) any Purchaser or any of its Affiliates make any
public announcement or issue any press release with respect to the transactions contemplated by this Agreement without consulting with the Company, on the one hand, and the Majority Purchasers, on the other hand, to the extent feasible, as to the
content of such public announcement or press release. Notwithstanding the foregoing, the parties agree that the Company shall issue a press release in the form of Exhibit G hereto promptly following (and in no event more than 24 hours
after) the Closing and, on or before 9:30 a.m., New York time, on the first trading day following the Closing Date, the Company shall file a Current Report on Form 8-K describing the terms of the transactions contemplated by this Agreement and the

to such filing (including all attachments, the “8-K Filing”, and the description and attachments, the “8-K Materials”). From and after the filing of the 8-K Filing with the SEC, no Purchaser shall be in possession of any
material, nonpublic information received from the Company, any of its Subsidiaries or any of its respective officers, directors, employees or agents, that is not disclosed in the 8-K Filing. The Company shall not, and shall cause each of its
Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide any Purchaser with any material nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the 8-K
Filing with the SEC without the express written consent of such Purchaser; provided that the Company shall not be responsible for any information obtained by any Purchaser or any Inspector (as defined in the Registration Rights Agreement) as a
result of such Purchaser’s exercise of its inspection rights under the Registration Rights Agreement; and provided further that in the event the Company or any of its Subsidiaries provides any information to a Purchaser under the Transaction
Documents and the Company reasonably believes that such information represents material nonpublic information, the Company (a) shall prior to such disclosure to any Purchaser notify such Purchaser of such belief and shall not provide such
information to any Purchaser which does not expressly consent to receive such information and (b) to the extent any 
  

 -19- 

 Purchaser determines not to receive such information, the Company shall be deemed not to be in breach of the original
obligation to provide such information. In the event of a breach of the foregoing covenant by the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided
herein or in the Transaction Documents, a Purchaser shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material non-public information without the prior approval by the
Company, its Subsidiaries, or any of its or their respective officers, directors, employees or agents; provided that the Purchaser will provide to the Company two Business Days’ advance notice prior to such disclosure, and shall refrain from
making such disclosure if the Company makes such disclosure during such two-day period. No Purchaser shall have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, shareholders or agents
for any such disclosure. made in compliance with this Section 6.3.

 6.5 Integration. The Company shall not sell, offer for sale or solicit
offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Shares or Warrants in a manner that would require the registration under the
Securities Act of the sale of the Shares or the issuance of the Warrants or any Warrant Shares to the Purchasers. 
  
 6.6 Reservation of Common Stock for Issuance; Listing of Shares. The Company agrees to reserve from its duly authorized capital stock the total
number of shares of Common Stock issuable upon execution of this Agreement and upon the exercise in full of all of the Warrants. The Company agrees that at any time, if and when its shares of Common Stock are listed on NASDAQ or any other securities
exchange, that it will use best efforts to promptly list and qualify the Shares and any Warrant Shares for trading on NASDAQ or such other securities exchange. 
  

6.7 Actions with respect to Securities Laws Exemptions. Neither the Company nor anyone acting on its behalf shall take any action that would
cause the loss of any Securities Laws Exemptions. 
  
 6.8
Restrictions on Certain Stock Issuances or Registrations. The Company agrees that prior to the effectiveness of the Mandatory Registration Statement (as defined in the Registration Rights Agreement), the Company shall not (i) issue any shares
of Common Stock, or securities convertible into or exercisable for shares of Common Stock, that could be eligible for sale without restriction under the Securities Act prior to the effectiveness of the Mandatory Registration Statement (as defined in
the Registration Rights Agreement), or (ii) grant any registration rights after the date hereof to any other Person that would entitle such Person to have the sale of securities held by such Person registered under the Securities Act by the
Company under a registration statement that is declared effective prior to the effectiveness of the Mandatory Registration Statement, provided, that this Section 6.8 shall not be deemed to restrict the ability of the Company to (a) issue shares of
Common Stock upon the exercise or conversion of any options, warrants, convertible debt instruments or other contingent securities outstanding on the date hereof, (b) issue shares, options or warrants in connection with the Teligent Acquisition or
to employees, directors or consultants of the Company or (c) perform its obligations in connection with the Teligent Acquisition.

reasonable efforts to promptly, and in any event no later than 30 days following the Closing Date, ascertain whether it is in compliance with Section 310(b) of the Communications Act (including, without limitation, by sending a questionnaire to
investors) and, to the extent any noncompliance is discovered, promptly take all commercially reasonable efforts necessary to remedy any noncompliance.
