WHEREAS, the Company desires to sell to the Purchasers (a) an aggregate principal amount of
$1,800,000 of the Company’s Senior Secured Convertible Term Notes bearing an annual interest rate
of 8% with a maturity date of five (5) years from the date of issuance (the “Tranche A

Company’s Common Stock (each such warrant a “Tranche A Warrant” and, collectively, the
“Tranche A Warrants”); and

WHEREAS, the Company desires to sell to the Purchasers (a) an aggregate principal amount of
$1,800,000 of the Company’s Senior Secured Convertible Term Notes bearing an annual interest rate
of 8% with a maturity date of five (5) years from the date of issuance (the “Tranche B
Notes” and, together with the Tranche A Notes, the “Notes”), in the form attached
hereto as Exhibit C, which are convertible into shares of the Company’s Common Stock, and
(b) a warrant, in the form attached hereto as Exhibit D, to purchase up to 4,500,000 shares
of the Company’s Common Stock (each such warrant a “Tranche B Warrant” and, collectively,
the “Tranche B Warrants” and, together with the Tranche A Warrants, the
“Warrants”); and

WHEREAS, the Purchasers, acting severally and not jointly, desire to purchase the Notes and
the Warrants on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises,
representations, warranties and covenants set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

	 	1.	 	Agreement to Sell and Purchase.

On the basis of the representations and warranties herein contained and subject to the
terms and conditions set forth in this Agreement and the Related Agreements, the Company
hereby agrees to sell to each Purchaser, and each Purchaser, acting severally and not
jointly, hereby agrees to purchase from the Company, the Securities as follows:

(a) on the First Closing (as defined herein), (i) a Tranche A Note in the principal
amount as is set forth opposite such Purchaser’s name on Exhibit E attached hereto
and (ii) a Tranche A Warrant to purchase the number of shares of Common Stock set forth
opposite such Purchaser’s name on Exhibit E attached hereto; and

(b) on the Second Closing (as defined herein), (i) a Tranche B Note in the principal
amount as is set forth opposite such Purchaser’s name on Exhibit E attached hereto
and (ii) a Tranche B Warrant to purchase the number of shares of Common Stock set forth
opposite such Purchaser’s name on Exhibit E attached hereto.

The purchase and sale of the Notes and Warrants, as set forth in Section 2 hereof, are
referred to herein as the “Offering.” Collectively, the Notes, the Warrants and the Common
Stock issuable upon conversion of the Notes and upon exercise of the Warrants are referred to as
the “Securities.” Wherever in this Agreement there is a reference to a specific number of
shares of Common Stock of the Company, or a price per share of such stock or exercise price per
share of such stock, then, upon the occurrence of any subdivision, combination, or stock dividend
of the Common Stock, the specific number of shares or the price so referenced in this Agreement
shall automatically be proportionally adjusted to reflect the affect on the outstanding shares of
Common Stock by such subdivision, combination, or stock dividend.

which the First Closing occurs, the “First Closing Date”).

(b) Second Closing. The purchase and sale of the Tranche B Notes and the
Tranche B Warrants pursuant to this Agreement (the “Second Closing”) shall, if it

The Company and AirGATE hereby make, jointly and severally, the following representations and
warranties to the Purchasers:

3.1 Organization, Good Standing and Qualification. Each of the Company and AirGATE is
a corporation duly organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and has the corporate power and authority to own and operate its
properties and assets, to execute and deliver (i) this Agreement, (ii) the Notes and the Warrants,
(iii) the Security Agreement dated as of even date herewith between the Company, AirGATE and each
Purchaser substantially in the form of Exhibit F (as amended, modified or supplemented from
time to time, the “Security Agreement”), (iv) the Registration Rights Agreement relating to
the Securities dated as of even date herewith between the Company and each Purchaser substantially
in the form of Exhibit G (as amended, modified or supplemented from time to time, the
“Registration Rights Agreement”), (v) the Guaranty Agreement dated as of even date herewith
between the Company, AirGATE and each Purchaser substantially in the form of Exhibit H (as
amended, modified or supplemented from time to time, the “Guaranty Agreement”), and (v) all
other agreements, documents or instruments contemplated hereunder or delivered pursuant hereto
(preceding clauses (iii)-(vi), collectively, the “Related Agreements”), to issue and sell
the Notes and the shares of Common Stock issuable upon conversion of the Notes (the “Note
Shares”), to issue and sell the Warrant and the shares of Common Stock issuable upon exercise
of the Warrants (the “Warrant Shares,”), and to carry out the provisions of this Agreement
and the Related Agreements and to carry on its respective business as presently conducted. Each of
the Company and AirGATE is duly qualified and is authorized to do business and is in good standing
as a foreign corporation in all jurisdictions in which it conducts its business, except for those
jurisdictions in which the failure to be so qualified and authorized has not had, or could not
reasonably be expected to have, individually or in the aggregate, a material adverse effect on the
business, assets, liabilities, condition (financial or otherwise), properties, operations or
prospects of the Company and AirGATE, taken individually and as a whole (a “Material Adverse
Effect”).

3.2 Subsidiaries. Except as disclosed on Schedule 3.2, the Company owns 100%
of the issued and outstanding shares of the capital stock of AirGATE free and clear of any and all
Liens (the “AirGATE Shares”) and has no Subsidiaries other than AirGATE. All the issued
and outstanding shares of capital stock of AirGATE are validly issued and are fully paid,
non-assessable and free of preemptive and similar rights. Other than AirGATE, the Company does not
own or control, directly or indirectly, any interest in any other corporation, association, or
other business entity. Neither the Company nor AirGATE is a participant in any joint venture,
partnership or similar arrangement. For the purpose of this Agreement, “Subsidiary” means
(i) a corporation or other entity whose shares of stock or other ownership interests having
ordinary voting power to elect a majority of the directors of such corporation, are owned, directly
or indirectly, by the Company or (ii) a corporation or other entity in which the Company owns,
directly or indirectly, more than 50% of the equity interests.

3.3 Capitalization; Voting Rights.

(a) The authorized capital stock of the Company, as of even date herewith, consists of
100,000,000 shares of Common Stock and 10,000,000 shares of Preferred Stock, par value
$0.001 per share (“Preferred Stock). As of the date hereof, 31,589,501 shares of
Common Stock were issued and outstanding, and no shares of Preferred Stock had been issued
or were outstanding. Set forth on Schedule 3.3(a)(i) is the Fully-Diluted Common

options, warrants, rights (including conversion or preemptive rights, rights of first
refusal or similar rights), proxy or stockholder agreements, or arrangements or agreements
of any kind for the purchase or acquisition from the Company or AirGATE of any of their
securities. Except as set forth on Schedule 3.3(b)(ii), neither the offer,
issuance or sale of any of the Notes, the Warrants or the issuance of the Note Shares or
Warrant Shares, nor the consummation of any of the transactions contemplated hereby will
result in a change in the price or number of any securities of the Company or AirGATE
outstanding, under anti-dilution or other similar provisions contained in or affecting any
such securities. The sale of the Notes and Warrants, the subsequent conversion of the
Notes into Note Shares and the Warrants into Warrant Shares and any of the transactions
contemplated under the Transaction Documents are not and will not be subject to any
preemptive rights, rights of first refusal, rights of first offer or any similar rights
that have not already been properly waived or complied with as of the date hereof.

(c) All issued and outstanding shares of the Company’s Common Stock: (i) have been
duly authorized and validly issued and are fully paid and nonassessable, and (ii) were
issued in compliance with all applicable state and federal Laws concerning the issuance of
securities.

(d) The rights, preferences, privileges and restrictions of the shares of the Common
Stock are as stated in the Company’s Certificate of Incorporation (the “Charter”).
The Note Shares and Warrant Shares have been duly and validly reserved for issuance, and
when issued in compliance with the provisions of the Transaction Documents, such shares
will be validly issued, fully paid and nonassessable, and will be free of any Lien;
provided, however, the Securities may be subject to restrictions on
transfer under state and/or federal securities Laws as set forth herein, or as otherwise
required by such Laws at the time a transfer is proposed.

3.4 Authorization; Binding Obligations. All corporate action on the part of the
Company, AirGATE, their officers and directors necessary for the valid authorization of the

issuance and reservation for issuance of the Note Shares and Warrant Shares), has been taken. The
Transaction Documents, the Note Share and Warrant Shares have been (or upon delivery will have
been) duly executed by the Company and when delivered in accordance with the terms hereof, will be
valid and binding obligations of the Company enforceable in accordance with their terms, except (i)
as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of
general application affecting enforcement of creditors’ rights and (ii) general principles of
equity that restrict the availability of equitable or legal remedies. Each of the Securities have
been duly and validly authorized for issuance by the Company and, when executed and delivered, will
be valid and binding obligations of the Company enforceable in accordance with their terms, except
(i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of
general application affecting enforcement of creditors’ rights and (ii) general principles of
equity that restrict the availability of equitable or legal remedies. No approval of the

affiliated therewith) shall be aggregated for the purpose of meeting the individual minimum
dollar amounts of such subsections.

3.7 Obligations to Related Parties. Except as set forth on Schedule 3.7,
there are no obligations of the Company or AirGATE to officers, directors, stockholders or
employees of the Company. None of the officers, directors or, to the Company’s or AirGATE’s

stockholder, or any member of their immediate families, is, directly or indirectly, interested in
any material contract with the Company or AirGATE and no agreements, understandings or proposed
transactions are contemplated between the Company or AirGATE and any such person. The Company is
not a guarantor or indemnitor of any indebtedness of any other person, firm or corporation.

leased, subleased, licensed or otherwise occupied (whether as tenant, subtenant or pursuant to
other occupancy arrangements) by the Company or AirGATE (collectively, including the improvements
thereon, the “Leased Real Property”), and for each parcel of Leased Real Property, contains
a correct street address of such Leased Real Property. Except as set forth on Schedule

assets, and valid leasehold interests in its Leased Real Property and leased assets, in each case
subject to no Lien, other than Permitted Liens. All facilities, machinery, equipment, fixtures,
vehicles and other properties owned, leased or used by the Company or AirGATE are, individually or
in the aggregate, in good operating condition and repair and are reasonably fit and usable for the
purposes for which they are being used. The Company and AirGATE are each in compliance with all
material terms of each lease to which such company is a party or is otherwise bound. Each lease is
in full force and effect and neither the Company nor AirGATE has received any notice of any default
or event that notice or lapse of time, or both, would constitute a default by the Company or
AirGATE under any such lease and, to the knowledge of the Company and AirGATE, no other party is in
default thereof, and no party to the lease has exercised any termination rights with respect
thereto.

3.10 Intellectual Property.

(a) Schedule 3.10 contains a complete and accurate list of all (i) issuances,
registrations and applications for Patents, Marks, Domain Names and Copyrights that the
Company or AirGATE owns or has filed or under which the Company or AirGATE has been granted
a license or other right, (ii) licenses, sublicenses, options or agreements to which the
Company or AirGATE is a party or by which the Company or AirGATE is bound and pursuant to
which the Company or AirGATE is granted a license or other right under any third party

(b) The Company or AirGATE, as the case may be, owns and possesses title to, or has
sufficient valid and enforceable licenses to use and otherwise exploit, all Intellectual
Property Rights set forth on Schedule 3.10 and all other material Company
Intellectual Property Rights as the same are used and otherwise exploited by the Company or
AirGATE in its business as now conducted and, to the Company’s and AirGATE’s knowledge, as
presently proposed to be conducted. The Company Intellectual Property Rights include all
Intellectual Property Rights necessary and sufficient to enable the Company and AirGATE to
conduct their respective business as now conducted.

(c) Neither the Company nor AirGATE has received any claim, notice or communication
alleging that the Company or AirGATE has infringed, misappropriated or violated any
Intellectual Property Rights of any third party or challenging the use, validity or
enforceability of any of the Company Intellectual Property Rights nor is the Company or
AirGATE aware of any basis therefor. To the Company’s and AirGATE’s knowledge, the conduct
of the Company’s and AirGATE’s respective business has not infringed, misappropriated,
constituted the misappropriation of or violated, and does not infringe, misappropriate,
constitute the misappropriation of or violate, any Intellectual Property Rights of any
third party. The transactions contemplated by this Agreement will have no material adverse
effect on the Company’s or AirGATE’s right, title or interest in and to the Intellectual
Property Rights listed on Schedule 3.10 or any other Company Intellectual Property
Rights, and all of such Intellectual Property Rights and Company Intellectual Property
Rights shall be owned or available for use by the Company or AirGATE on substantially
identical terms and conditions immediately after Closing.

of their respective employees made prior to their employment by the Company or AirGATE, as
the case may be, are utilized in the conduct of the business of the Company or AirGATE,
except for such Intellectual Property Rights that have been rightfully and validly assigned
to the Company or AirGATE in writing. Each employee, consultant and independent contractor
of the Company or AirGATE has entered into a written non-disclosure and invention
assignment agreement with the Company or AirGATE, as the case may be. The Company and
AirGATE have taken commercially reasonable steps to maintain and protect their Trade
Secrets.

obligated under any contract (including any license, covenant or commitment of any nature)
or other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee’s best efforts to
promote the interests of the Company or AirGATE, as the case may be, or that would conflict
with the Company’s or AirGATE’s business. Neither the execution nor the delivery of the
Transaction Documents, nor the carrying on of the Company’s or AirGATE’s business by the
employees of such company, will, to the Company’s and AirGATE’s knowledge, conflict with or
result in a breach of any of the terms, conditions or provisions of, or constitute a
default under, any contract, covenant or instrument under which any of such employees is
now obligated.

3.11 Compliance with Other Instruments. The execution and delivery by the Company of
the Transaction Documents, the issuance of the Securities, and the consummation by the Company and
AirGATE of the other transactions contemplated hereby and thereby do not, and compliance with the
provisions of the Transaction Documents will not, conflict with, or result in any violation of, or
default (with or without notice or lapse of time, or both) under, or give rise to a right of
termination, cancellation or acceleration of any obligation or loss of a material benefit under, or
result in the creation of any Lien upon any of the properties or assets of the Company or AirGATE
under, or result in the termination of, or require that any consent be obtained or any notice be
given with respect to (i) the Charter, Bylaws or other organizational documents of the Company or
AirGATE, in each case as amended to the date of this Agreement, (ii) any loan or credit agreement,

applicable to the Company or AirGATE or their respective properties or assets or (iii) any Law
applicable to, or any judgment, decree or order of any Governmental Body having jurisdiction over,
the Company or AirGATE or any of their respective properties or assets.

3.12 Litigation. Except as set forth in Schedule 3.12, there is no Action
pending or, to the Company’s knowledge, currently threatened against the Company that questions the
validity of, or prevents the Company from entering into, the Transaction Documents, or from
consummating the transactions contemplated hereby or thereby, or which has had, or could reasonably
be expected to have, either individually or in the aggregate, a Material Adverse Effect or could
result in any change in the current equity ownership of the Company, nor is the Company aware that
there is any basis to assert any of the foregoing. Neither the Company nor AirGATE is a party or
subject to the provisions of any order, writ, injunction, judgment or decree of any Governmental
Body. There is no Action by the Company or AirGATE currently pending or which the Company or
AirGATE intends to initiate. Neither the Company nor AirGATE, nor any director or officer thereof,
is or has been the subject of any Action involving a claim of violation of or liability under
federal or state securities Laws or a claim of breach of fiduciary duty.

Company and AirGATE have duly and timely filed all Tax Returns required to be filed by or on behalf
of the Company or AirGATE in all jurisdictions in which such Tax Returns are required to be filed,
and all such Tax Returns are true, complete and correct in all material respects. All Taxes shown
to be due and payable on such Tax Returns, any assessments imposed, and all other Taxes due and
payable by the Company have been fully and timely paid or will be fully and timely paid prior to
the time they become delinquent. Neither the Company nor AirGATE has been advised:

(a) that any of its Tax Returns have been or are being audited; or

(b) of any deficiency in assessment or proposed judgment to its Taxes.

Neither the Company nor AirGATE has any knowledge of any liability of any Tax to be imposed
upon its properties or assets for which adequate reserves have not been established. With respect
to any period for which Tax Returns have not yet been filed or for which Taxes are not yet due or
owing, the Company and AirGATE have made due and sufficient accruals for such Taxes on their books
in accordance with GAAP. No claim has been made by any governmental authority in a jurisdiction
where the Company or AirGATE does not file Tax Returns such that it is or may be subject to
taxation by that jurisdiction. Neither the Company nor AirGATE is a party to or bound by any Tax
sharing agreement or Tax indemnity agreement, arrangement or practice. Neither the Company nor
AirGATE has entered into a “listed transaction” within the meaning of Treasury Regulations §
1.6011-4(b).

3.14, neither the Company nor AirGATE is presently under any obligation, and neither the
Company nor AirGATE has granted any rights (including, “piggy-back” registration rights),
to register with the SEC or any other Governmental Body any of the Company’s or AirGATE’s presently
outstanding securities or any of its securities that may hereafter be issued. To the Company’s or
AirGATE’s knowledge, no stockholder of the Company or AirGATE has entered into any agreement with
respect to the voting of equity securities of the Company or AirGATE.

3.15 Compliance with Laws; Permits. Neither the Company nor AirGATE is in violation
of any applicable Law of any Governmental Body thereof in respect of the conduct of its business or

consents, approvals or authorizations are required to be obtained and no registrations or
declarations are required to be filed in connection with the execution and delivery of the
Transaction Documents and the issuance of any of the Securities, except such as has been duly and
validly obtained or filed. Each of the Company and AirGATE has all material franchises, permits,
licenses and any similar authority necessary for the conduct of its business as now being conducted
by it, the lack of which could, either individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect.

3.16 Environmental and Safety Laws. Except as set forth in Schedule 3.16,
neither the Company nor AirGATE is in material violation of any Environmental Law, and to its
knowledge, no material expenditures are or will be required in order to comply with any such
existing Law. The Company and AirGATE (i) have received all permits, license or other approvals
required of them under applicable Environmental Laws to conduct their respective businesses and
(ii) are in compliance with all terms and conditions of any such permit, license or approval. No
Hazardous Materials (as defined below) are used or have been used, stored, or disposed of by the
Company or AirGATE, or, to the Company’s or AirGATE’s knowledge, by any other person or entity on
any property owned, leased or used by the Company or AirGATE, as the case may be. For the purposes
of the preceding sentence, “Hazardous Materials” shall mean:

(a) materials which are listed or otherwise defined as “hazardous” or

protection of the environment from contamination, the control of hazardous wastes, or other
activities involving hazardous substances, including building materials; or

(b) any petroleum products or nuclear materials.

3.17 Valid Offering; No Integrated Offering.

(a) Assuming the accuracy of the representations and warranties of the Purchasers
contained in this Agreement, the offer, sale and issuance of the Securities will be exempt
from the registration requirements of the Securities Act of 1933, as amended (the
“Securities Act”), and are exempt from registration and qualification under the
registration, permit or qualification requirements of all applicable state securities Laws.

(b) Neither the Company, nor AirGATE or their 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 the Transaction Documents 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 Rule 506 under the Securities Act, or any
applicable exchange-related stockholder approval provisions.

3.18 Insurance. The Company or AirGATE, as the case may be, is insured by insurers of
recognized financial responsibility against such losses and risks and in such amounts as are
prudent and customary for companies similarly situated to the Company or AirGATE in the same or
similar business. The Company and AirGATE have no reason to believe that it will not be able to

	 	5.	 	Covenants of the Company.

The Company hereby covenants to each Purchaser, as of each the First Closing and the Second

5.1 Reporting Requirements. The Company will timely file with the SEC all reports

5.2 Taxes. The Company and AirGATE will promptly pay and discharge, or cause to be
paid and discharged, when due and payable, all lawful Taxes, assessments and governmental charges
or levies imposed upon the income, profits, property or business of the Company or AirGATE;
provided, however, that any such Tax, assessment, charge or levy need not be paid
if the validity thereof shall currently be contested in good faith by appropriate proceedings and
if the Company or AirGATE, as applicable, shall have set aside on its books adequate reserves with
respect thereto, and provided, further, that the Company or AirGATE, as applicable, will pay all
such Taxes, assessments, charges or levies forthwith upon the commencement of proceedings to
foreclose any Lien which may have attached as security therefor.

5.3 Insurance. The Company will keep its properties and assets which are of an
insurable character insured by financially sound and reputable insurers against loss or damage by
fire, explosion and other risks customarily insured against by companies in similar business
similarly situated as the Company, and the Company will maintain, with financially sound and
reputable insurers, insurance against other hazards and risks and liability to persons and property
to the extent and in the manner which the Company reasonably believes is customary for companies in
similar business similarly situated as the Company and to the extent available on commercially

full risk of loss from any loss of any nature whatsoever with respect to the assets pledged to the
Purchasers as security for its obligations hereunder and under the Transaction Documents. At the
Company’s own cost and expense in amounts customarily insured against by companies in similar
business similarly situated as the Company and with carriers reasonably acceptable to the
Purchasers, the Company and each of the Subsidiaries shall (i) keep all its insurable properties
and properties in which it has an interest insured against the hazards of fire, flood, sprinkler
leakage, those hazards covered by extended coverage insurance and such other hazards, and for such
amounts, as is customary in the case of companies engaged in businesses similar to the Company’s or
the respective Subsidiary’s including business interruption insurance; (ii) maintain public and
product liability insurance against claims for personal injury, death or property damage suffered
by others; (iii) maintain all such worker’s compensation or similar insurance as may be required
under the Laws of any state or jurisdiction in which the Company or the Subsidiary is engaged in

thereto.

5.4 Maintenance of Rights. The Company shall maintain in full force and effect its
corporate existence, rights and franchises and all licenses and other Intellectual Property Rights
owned or possessed by it and reasonably deemed to be necessary to the conduct of its business.

5.5 Properties. The Company will keep its properties in good repair, working order
and condition, reasonable wear and tear excepted, and from time to time make all needful and proper
repairs, renewals, replacements, additions and improvements thereto. The Company will at all times
comply with each provision of all leases to which it is a party or under which it occupies property
if the breach of such provision could reasonably be expected to have a Material Adverse Effect on
the Company.

5.6 Confidentiality; Press Release. Neither the Company nor any Purchaser shall (i)
issue or caused the publication of any press release or other public announcement with respect to
the Transaction Documents or the transactions contemplated thereunder without the prior written
consent of the other parties (which consent shall not be unreasonably withheld, conditioned or
delayed), except as may be required by applicable Law. The Company will not disclose, and will not
include in any press release or public announcement, the names of the Purchasers, unless agreed to
in writing by the Purchasers or unless and until such disclosure is required by Law, and then only
to the extent of such requirement. The Company may disclose the Purchasers’ identities and the
terms of this Agreement to its current and prospective debt and equity financing sources.

5.7 Reissuance of Securities. The Company shall reissue certificates representing the
Securities without the legends set forth in Section 4.8 above at such time as:

(a) the holder thereof is permitted to dispose of such Securities pursuant to Rule
144(k) under the Securities Act; or

(b) upon resale subject to an effective registration statement after such Securities
are registered under the Securities Act or resale in accordance with Rule 144 under the
Securities Act.

The Company agrees to cooperate with the Purchasers in connection with all resales of any of
the Securities pursuant to Rule 144, and provide legal opinions (at the Company’s expense)
necessary to allow such resales, provided the Company and its counsel receive reasonably requested
representations from the selling Purchaser and its broker(s), if any.

5.8 Preemptive Rights. If the Company proposes to issue any shares of its capital
stock for cash in a transaction other than a transaction in which shares of the Common Stock are
issued in connection (i) with an acquisition (x) of all of the capital stock (or equivalent form of
ownership) of a third party or (y) of all or substantially all of the operating assets (whether
tangible or intangible) of a third party, (ii) to any officers, directors or employees under any
stock option plan or other incentive plan approved by the Company’s board of directors, or (iii)
with an offering of the Company’s shares by a nationally recognized underwriter such that the
Company’s aggregate net proceeds are at least $20,000,000 and the imputed market capitalization of
the Company, pre-sale, is at least $100,000,000 (a “Qualified Offering”), the Company
shall, subject to the Company’s preexisting obligations as of the date hereof to offer all of such
shares to a previous investor in the Company, offer to sell such number of shares to each Purchaser
equal to such Purchaser’s fully diluted percentage ownership in the Company, on the terms and
conditions the Company proposes to offer such shares to third parties. If and to the extent the
Purchasers are offered any such shares of the Company’s capital stock, each Purchaser will have
fifteen (15) days from the date of receipt of such written offer to exercise its rights to acquire
such shares on the same terms and conditions as such shares would be offered to third parties, or
lose such rights with respect to such shares; provided, however, that any shares offered to third
parties shall be on terms no more favorable to the terms offered to the Purchasers. For purposes
of this Section 5.8, the term “fully diluted percentage ownership” shall mean that
number of shares of Common Stock that would be held by each Purchaser upon conversion of all Notes
and Warrants held by such Purchaser divided by the total number of shares of Common Stock owned by
all stockholders of the Company (including such Purchaser) after giving effect to all conversions
or exercises into Common Stock of all derivative securities held by all such stockholders.

5.9 Observer Rights. With respect to the Company and each of its Subsidiaries, the
Required Purchasers shall have the right to send one non-voting observer (the “Non-Voting
Observer”) to all meetings of the board of directors or other applicable governing body of such
entity, provided (i) the Non-Voting Observer shall enter into an appropriate confidentiality
agreement regarding all confidential information so received, and (ii) that the Company reserves
the right to exclude the Non-Voting Observer from access to any of such materials or meetings or
portions thereof if (A) the Company reasonably considers any such material or portion thereof to be
a trade secret or similar confidential information, (B) the Company believes, upon advice of
counsel, that such exclusion is reasonably necessary to preserve the attorney-client privilege, (C)
in the judgment of a majority of the Board, such access would materially impair the due
consideration by the Board of any matter, or (D) in the judgment of the Board or upon advice of
counsel such access will disclose to the Non-Voting Observer material non-public information. The
Company and each of its Subsidiaries shall use their reasonable best efforts to provide the
Purchasers with notice of all meetings of its respective board of directors or other applicable
governing body of such entity consistent with that provided to the official members of board of
directors or other applicable governing body of such entity; provided, however, that the failure to
give such notice shall not invalidate any action taken by the board of directors or other
applicable governing body of such entity at the meeting. The foregoing notwithstanding, at such
time as the Purchasers or their Affiliates own, in the aggregate, less than the principal amount of
$500,000 of the Notes, the Purchasers shall lose their right to have the Non-Voting Observer.

5.10 Fair Market Value of Options. The Company will not grant any options to acquire
capital stock of the Company to any officer, director, employee or consultant having an exercise
price that is less than the fair market value of such capital stock on the date of such grant.

5.11 Use of Proceeds. The Company agrees that it will use the proceeds of the sale of
the Notes and Warrants to continue development and commercialization of the drill pipe RFID tagging
project and for general working capital purposes only.

traded on any Trading Market, it will include in such application the Note Shares and the Warrant
Shares, and will take such other action as is necessary or desirable to cause the Note Shares and
Warrant Shares to be listed on such Trading Market as promptly as possible, and (ii) it will take
all action reasonably necessary to continue the quotation of its Common Stock on the OTCBB or the
listing and trading of its Common Stock on a Trading Market and will comply in all material
respects with the Company’s reporting, filing and other obligations under the bylaws or rules of
the OTCBB or the Trading Market.

5.13 Filings. The Company shall timely make all necessary SEC and other governmental
filings required to be made by the Company in connection with the Transaction Documents and the
issuance of the Securities to the Purchasers as required by all applicable Law, and shall provide a
copy thereof to the Purchasers promptly after such filing.

5.14 Corporate Existence. So long as any Purchaser beneficially owns any Notes or
Warrants, the Company and AirGATE shall maintain their corporate existence.

5.15 Integration. The Company shall not sell, offer for sale or solicit offers to buy
or otherwise negotiate in any security (as defined in Section 2 of the Securities Act) that would
be integrated with the offer or sale of the Securities in a manner that would require the
registration under the Securities Act of the sale of the Securities.

5.16 Financial Information. So long as a Purchaser beneficially owns any Notes or
Warrants, unless the following are filed with the SEC through EDGAR and are available to the public
through the EDGAR system, the Company agrees to send the following to the Purchasers within one (1)

Quarterly Reports on Form 10-Q, any Current Reports on Form 8-K and any registration statements
(other than on Form S-8) or amendment filed pursuant to the Securities Act (“SEC

it shall notify such Purchaser when quarterly or annual financial information becomes available and
shall, upon subsequent request from any Purchaser, provide such Purchaser with the quarterly or
annual financial information, quarterly updates regarding the Company’s and AirGATE’s business, and
other information which would have otherwise been filed with the SEC. Upon any Purchaser’s
request, the Company will provide a copy of the Company’s annual operating plan thirty (30) days
prior to the beginning of the Company’s fiscal year.

5.17 Access to Facilities. Each of the Company and AirGATE will permit any
representatives designated by the Required Purchasers (or any successor of the Purchasers) (the
“Purchaser Representatives”), upon reasonable notice and during normal business hours at
such person’s expense and accompanied by a representative of the Company, to:

(a) visit and inspect any of the properties of the Company or AirGATE;

(b) examine the corporate and financial records of the Company or AirGATE (unless such
examination is not permitted by federal, state or local Law or by contract) and make copies
thereof or extracts therefrom; and

(c) discuss the affairs, finances and accounts of the Company or AirGATE with the
directors, officers and independent accountants of the Company or AirGATE.

Notwithstanding the foregoing, the Purchaser Representatives shall only be allowed to access to
facilities as set forth in this Section 5.17, provided (i) all Purchaser Representative
shall enter into an appropriate confidentiality agreement regarding all confidential information so
received, and (ii) that the Company reserves the right to exclude Purchaser Representatives from
access to any of such materials or meetings or portions thereof if (1) the Company reasonably
considers any such material or portion thereof to be a trade secret or similar confidential
information, (2) the Company believes, upon advice of counsel, that such exclusion is reasonably
necessary to preserve the attorney-client privilege, (3) in the judgment of a majority of the
Board, such access would materially impair the due consideration by the Board of any matter, or (4)
in the judgment of the Board or upon advice of counsel such access will disclose to the Purchaser
Representatives material non-public information.

5.18 Reservation of Shares. The Company shall maintain a reserve from its duly
authorized shares of Common Stock to comply with its obligations under the Notes and the Warrants.
