During the period commencing on the 41^st Trading Day following the earlier to occur of the ARRA Negative Funding Announcement Date or September 30, 2010 through the date immediately preceding the Maturity Date, the Lender may, in its sole discretion and upon 10 Business Days’ prior written notice to the Company, convert all or a portion of the indebtedness of the Company outstanding on such date under this Note into that number of shares of Series Cal Cap Preferred Stock which is equal to the quotient obtained by dividing (a) the sum of (i) the then outstanding principal amount of this Note and (ii), any accrued but unpaid interest thereon elected by the Lender to be so converted by (b) the lesser of (i) $0.75 (subject to appropriate adjustments for any stock dividend, stock split, stock combination, reclassification or similar transaction after the date hereof) and (ii) the average VWAP for the 40 Trading Days following the earlier to occur of the ARRA Negative Funding Announcement Date or September 30, 2010 (subject to appropriate adjustments for any stock dividend, stock split, stock combination, reclassification or similar transaction after the date hereof) (such lesser number being the “Post Announcement Conversion Price”). Any accrued but unpaid interest not converted into shares of Series Cal Cap Preferred Stock as provided in the preceding sentence shall be paid in cash on such date. Prior to the execution of this Note, the Company shall have reserved and set aside for issuance to the Lender such number of shares of Series Cal Cap Preferred Stock as would be issuable upon conversion of the Note pursuant to this Section 5(a).

(b) Conversion Upon the ARRA Grant Funding. In the event that any indebtedness under this Note remains outstanding at the time of any ARRA Grant Funding that occurs on or

before September 30, 2010, then the principal amount under this Note then outstanding and, at the option of the Lender, any accrued but unpaid interest thereon shall automatically convert at the time of such ARRA Grant Funding into that number of shares of Series Cal Cap Preferred Stock which is equal to the quotient obtained by dividing (a) the sum of (i) the then outstanding principal amount of this Note and (ii) all accrued but unpaid interest hereunder elected by the Lender to be so converted by (b) $1.50 (subject to appropriate adjustments for any stock dividend, stock split, stock combination, reclassification or similar transaction after the date hereof). All accrued but unpaid interest not converted into shares of Series Cal Cap Preferred Stock as provided in the preceding sentence shall be paid in cash within three (3) Business Days following the date of such ARRA Grant Funding. Prior to the execution of this Note, the Company shall have reserved and set aside for issuance to the Lender such number of shares of Series Cal Cap Preferred Stock as would be issuable upon conversion of the Note pursuant to this Section 5(b).

(c) Conversion or Repayment Upon Maturity. In the event that any indebtedness under this Note remains outstanding on the Maturity Date, then the principal amount under this Note then outstanding and any accrued but unpaid interest thereon shall, at the option of the Lender, either (a) become immediately due and payable on such date, or (b) convert on such date into that number of shares of Series Cal Cap Preferred Stock which is equal to the quotient obtained by dividing (i) the sum of (A) the then outstanding principal amount of this Note and (B) any accrued but unpaid interest thereon elected by the Lender to be so converted by (ii) the Post Announcement Conversion Price. Any accrued but unpaid interest not converted into shares of Series Cal Cap Preferred Stock as provided in the preceding sentence shall be paid in cash on the Maturity Date. Prior to the execution of this Note, the Company shall have reserved and set aside for issuance to the Lender such number of shares of Series Cal Cap Preferred Stock as would be issuable upon conversion of the Note pursuant to this Section 5(c).

(d) Mandatory Conversion. Notwithstanding anything herein to the contrary, if after September 30, 2010, the VWAP for each of any 10 consecutive Trading Days, which period shall have commenced only after September 30, 2010 (such period the “Threshold Period”), exceeds the product of (A) 5 and (B) the Post Announcement Conversion Price, the Company may, within 2 Trading Days after the end of any such Threshold Period, deliver a written notice to the Lender (a “Forced Conversion Notice” and the date such notice is delivered to the Lender, the “Forced Conversion Notice Date”) to cause the Lender to immediately convert all or part of the then outstanding principal amount of this Note plus, if so specified in the Forced Conversion Notice, accrued but unpaid interest, into that number of shares of Common Stock which is equal to the quotient obtained by dividing (a) the sum of (i) the then outstanding principal amount of this Note and (ii) all accrued but unpaid interest specified in the Forced Conversion Notice by (b) the Post Announcement Conversion Price. The date of conversion for purposes of Section 5(d) shall be deemed to occur on the tenth Trading Day following the Forced Conversion Notice Date. Any accrued but unpaid interest not converted into shares of Series Cal Cap Preferred Stock as provided in this subsection (d) shall be paid in cash on the date of such conversion.

(e) Issuance of True-Up Shares. If during the 40 Trading Day period immediately following any conversion of indebtedness specified in subsection (b) of this Section 5 (an “ARRA Conversion”) the average VWAP for such period is less than the applicable price at which such ARRA Conversion was effected, the Company shall immediately issue to the Lender

at the end of such 40 Trading Day period an additional number of shares of Series Cal Cap Preferred Stock (such shares, “True Up Shares”), such that the quotient obtained by dividing (a) the indebtedness of the Company hereunder so converted in connection with such ARRA Conversion by (b) the sum of (i) the shares of Series Cal Cap Preferred Stock issued in connection with the ARRA Conversion and (ii) such True Up Shares, equals the average VWAP for such period.

(f) Issuance of Certificates. As soon as is reasonably practicable after a conversion has been effected (but in any event within five (5) Business Days thereafter), the Company shall deliver to the Lender a certificate or certificates representing the number of shares of Series Cal Cap Preferred Stock or Common Stock, as the case may be, issuable by reason of such conversion in such name or names and in such denomination or denominations as the Lender may specify.

(g) No Fractional Shares. If any fractional share of Series Cal Cap Preferred Stock or Common Stock would, except for the provisions hereof, be deliverable upon conversion of this Note, the Company, in lieu of delivering such fractional share, shall pay an amount equal to the value of such fractional share, as determined by the per share conversion price used to effect such conversion.

(h) Issuance Costs. The issuance of certificates for shares of capital stock issuable upon conversion of this Note shall be made without charge to the Lender for any documentary stamp tax in respect thereof or other cost incurred by the Company in connection with such conversion and the related issuance of such shares of Series Cal Cap Preferred Stock or Common Stock, as applicable, provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Lender so converted and the Company shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. Upon conversion of this Note, the Company shall take all such actions as are necessary in order to ensure that the Series Cal Cap preferred Stock or the Common Stock issuable with respect to such conversion, as the case may be, shall be validly issued, fully paid and nonassessable.

(i) Compliance with Laws and Regulations. The Company shall take all such actions as may be necessary to assure that all shares of capital stock issued upon conversion of this Note may be so issued without violation of any applicable law or governmental regulation or any requirement of any domestic securities exchange upon which such shares of capital stock may be listed (except for official notice of issuance which shall be immediately delivered by the Company upon such issuance).

6. Affirmative Covenants. So long as any indebtedness under this Note remains outstanding, the Company shall:

(a) Compliance with Laws. Comply in all material respects with applicable laws, rules, regulations and orders, such compliance to include, without limitations, paying before the same become delinquent all taxes, assessments, and charges imposed upon it or upon its property

(iii) such other statements, lists of property and accounts, budgets, forecasts, projections, reports, or other information as the Lender may from time to time reasonably request

(d) Notice of Defaults and Events of Defaults. Provide to the Lender, as soon as possible and in any event within three (3) days after the occurrence thereof, with written notice of each event which either (i) is an Event of Default, or (ii) with the giving of notice or lapse of time or both would constitute an Event of Default, in each case setting forth the details of such event and the action which is proposed to be taken by the Company with respect thereto.

(e) Governmental Approvals. Promptly obtain and maintain any and all authorizations, consents, approvals, licenses, franchises, concessions, leases, rulings, permits, certifications, exemptions, filings or registrations by or with any Governmental Authority necessary for the Company to conduct its business and own (or lease) its properties or to execute, deliver and perform the Convertible Note Documents, except where the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

(f) Insurance. Promptly obtain and maintain in full force and effect at all times with responsible insurance companies such insurance covering its assets and properties, in such amounts and against such risks and with such deductibles as an enterprise conducting a similar business under similar business conditions as the Company would customarily maintain, except where the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

(g) Continuance of Business. Maintain its legal existence, licenses and privileges in good standing under and in compliance with all applicable laws and continue to operate the

business currently conducted by the Company and its Subsidiaries, except where the failure to maintain any such licenses or privileges could not reasonably be expected to result in a Material Adverse Effect. Without limiting the generality of the foregoing, the Company shall do and cause to be done all things necessary to apply for, preserve, maintain and keep in full force and effect all of its registrations of trademarks, service marks and other marks, trade names and other trade rights, patents, copyrights and other intellectual property in accordance with prudent business practices, except where the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

(h) Taxes. Pay and discharge (i) all federal and other material taxes, fees, assessments and governmental charges or levies imposed upon it or upon its properties or assets prior to the date on which penalties attach thereto, and all lawful claims for labor, materials and supplies which, if unpaid, might become a Lien (other than a Permitted Lien) upon any of its properties or assets, except to the extent such taxes, fees, assessments or governmental charges or levies, or such claims, are being contested in good faith by appropriate proceedings and are adequately reserved against in accordance with GAAP; and (ii) all other lawful claims which, if unpaid, would by law become a Lien upon its property not constituting a Permitted Lien.

(j) Post-Closing Covenant. By no later than 10 Business Days after the date hereof, the Company shall (i) deliver to the Lender all stock certificates evidencing the equity interests of KeyOn Communications, Inc. owned by the Company as of the date hereof, together with executed but undated stock powers and (ii)(A) repay in full all indebtedness of the Company owing to Horizon Federal Savings Bank in connection with the Horizon Federal Savings Bank Loan and (B) effect the release, in a manner reasonably satisfactory to the Lender, of all Liens of Horizon Federal Savings Bank in the assets of the Company which secure indebtedness of the Company arising under or in connection with the Horizon Federal Savings Bank Loan.

(ii) The Lender shall also have any other rights which the Lender may have been afforded under any contract or agreement at any time and any other rights which the Lender may have pursuant to applicable law. The Lender may exercise any and all of its remedies under this Note, the Agreement, the Guaranty, the Collateral Documents and the other Convertible Note Documents contemporaneously or separately from the exercise of any other remedies hereunder or under applicable law.

10. Lost, Stolen, Destroyed or Mutilated Note. In case this Note shall be mutilated, lost, stolen or destroyed, the Company shall issue a new Note of like date, tenor and denomination and deliver the same in exchange and substitution for and upon surrender and cancellation of any such mutilated Note, or in lieu of any such Note lost, stolen or destroyed, upon receipt of evidence satisfactory to the Company of the loss, theft or destruction of any such Note.

11. Governing Law. This Note is to be construed in accordance with and governed by the laws of the State of New York. The provisions of Section 5.3 of the Agreement relating to venue, submission to jurisdiction and the waiver of the right to jury trial are by this reference incorporated herein, mutatis mutandis, as if set forth herein in full.

12. Amendment and Waiver. Any term of this Note may be amended and the observance of any term of this Note may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Lender.

13. Notices. Except as may be otherwise provided herein, all notices, requests, waivers and other communications made pursuant to this Note shall be made in accordance with Section 5.6 of the Agreement.

14. Severability. If one or more provisions of this Note are held to be unenforceable under applicable law, such provision shall be excluded from this Note and the balance of the Convertible Note shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms.

15. Assignment. The Company shall not have the right to assign its rights and obligations hereunder or any interest herein.

16. Remedies Cumulative; Failure or Indulgence Not a Waiver. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Convertible Note Documents. No failure or delay on the part of the Lender in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

17. Payments. Whenever any payment of cash is to be made by the Company to any Person pursuant to this Note, such payment shall be made in lawful money of the United States of America by a check drawn on the account of the Company and sent via overnight courier service to such Person at such address as previously provided to the Company in writing (which address, in the case of the Lender as of the date of issuance hereof, shall initially be the address for the Lender as set forth in the Agreement); provided that the Lender may elect to receive a payment of cash via wire transfer of immediately available funds by providing the Company with prior written notice setting out such request and the Lender’s wire transfer instructions. Whenever any payment to be made shall otherwise be due on a day which is not a Business Day, such payment shall be made on the immediately succeeding Business Day and such extension of time shall be included in the computation of accrued interest.

18. Excessive Interest. Notwithstanding any other provision herein to the contrary, this Note is hereby expressly limited so that the interest rate charged hereunder shall at no time exceed the maximum rate permitted by applicable law. If, for any circumstance whatsoever, the interest rate charged exceeds the maximum rate permitted by applicable law, the interest rate shall be reduced to the maximum rate permitted, and if the Lender shall have received an amount that would cause the interest rate charged to be in excess of the maximum rate permitted, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing hereunder (without charge for prepayment) and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal, such excess shall be refunded to the Company.

19. Facsimile Transmission of Signature Page. The delivery of any executed signature page to this Note by telecopy or other electronic imaging means shall be effective as delivery of a manually executed signature page to this Note.

20. Waiver of Notice. To the extent permitted by law, the Company hereby waives demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the Convertible Note Documents.
