SECOND AMENDED AND RESTATED
CONVERTIBLE PROMISSORY NOTE



$11,137,321		June 13, 2008

FOR VALUE RECEIVED, each of the undersigned, ▇▇▇▇ INDUSTRIES, INC., a California corporation (the “Maker” or the “Company”) and ▇▇▇▇ INDUSTRIES, INC., a Minnesota corporation (together with Maker, referred to herein collectively as the “Obligors”), hereby jointly and severally promise to pay to the order of Newcastle Partners, L.P. a Texas limited partnership, or its assigns (the “Payee”), at such place as the Payee may designate in writing, the principal sum of $11,137,321 (Eleven Million One Hundred Thirty Seven Thousand Three Hundred Twenty One Dollars), or such other amount as shall equal the outstanding principal amount hereof, under the terms set forth herein. Capitalized terms used but not defined herein shall have the respective meanings given to such terms in the Purchase Agreement, dated as of January 31, 2007 (the “Purchase Agreement”), between the Maker and the Payee, unless the provisions of this Note indicate otherwise. This Second Amended and Restated Convertible Promissory Note is referred to herein as the “Note”.

1. Interest. Except as otherwise provided herein, the unpaid principal balance hereof from time to time outstanding shall bear interest from the date hereof at the rate of four percent (4%) per annum unless otherwise provided in this Note. Interest shall accrue on the outstanding unpaid principal amount (as increased pursuant to Section 2(a) below) until such principal amount is paid (or converted as provided herein) from the date hereof. Interest on this Note shall be computed on the basis of a 365-day year.

2. Payment of Interest and Principal. Except as otherwise provided herein (including, without limitation, Section 5 hereof), and subject to any default hereunder, the principal and interest hereof is payable as follows:

(a) Interest shall be paid in kind and shall accrete as additional principal on this Note on the applicable interest payment date; provided that, following January 31, 2009, if the Current Market Price at the date of election (which shall be on or following January 31, 2009) is at least 200% of the Conversion Price (as defined in Section 3(b)), interest on the then outstanding principal balance of this Note may be paid in cash at the election of Maker; provided further that, if such election to pay cash interest is made, the interest rate set forth in Section 1 hereof shall be increased to the lesser of (a) eight percent (8%) or (b) the highest lawful interest rate permitted by applicable law; and provided further that any accrued interest as of the date of such election shall accrete as additional principal on this Note as of such election date. Interest shall be payable in arrears on December 31, March 31, June 30 and September 30 of each year. All references herein to the “principal” of this Note shall include all interest accreted thereon as additional principal pursuant to the foregoing sentence.

(b) The entire outstanding principal amount of the Note together with all accrued but unpaid interest shall be due in cash on January 31, 2017 (the “Maturity Date”) from the Obligors.

(c) On and following January 31, 2010, so long as the Current Market Price (determined on the date of prepayment) is greater than 200% of the Conversion Price, the Maker will have right of early prepayment of this Note at an amount equal to 105% of the aggregate outstanding principal on this Note. For the purposes of this Note, the “Current Market Price” on any date means the average of the daily Closing Prices per share of Common Stock for all Trading Days included in 90 consecutive calendar days preceding the date in question. For purposes of the foregoing, (i) the “Closing Price” shall be the last reported sales price or, if no such reported sale takes place on any particular date, the average of the reported closing bid and asked prices on the principal exchange on which the Common Stock is listed (or if the Common Stock is not so listed, the average of the closing bid and asked prices furnished by any two members of the Financial Industry Regulatory Authority (FINRA) as selected by Payee for such purpose) on the date in question and (ii) “Trading Days” shall mean any day on which the market on which the Common Stock is then traded is open for trading. Any such prepayment under this Section 2(c) shall be on 30 days advance notice to Payee.

3. Conversion at the Option of Payee.

(a) At any time while any portion of the principal or interest of this Note is outstanding, the Payee may give the Maker written notice of its intention to convert all or any portion of the outstanding principal and/or accrued but unpaid interest on this Note into such number of shares of the Maker’s common stock (the “Common Stock”), equal to the amount to be converted divided by the Conversion Price in effect at such time. Upon receipt of the Payee’s written notice, the Maker shall cause certificates representing those shares to be delivered to Payee within three business days of Maker’s receipt of such notice. The person or persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be

treated for all purposes as the record holder or holders of such shares of Common Stock on the date the applicable conversion notice is given.

(b) The “Conversion Price” shall be $0.20 per share of Common Stock, subject to any adjustment. The Conversion Price shall be adjusted proportionally for any subsequent stock dividend or split, stock combination or other similar recapitalization, reclassification or reorganization of or affecting Maker’s Common Stock. In addition, the Conversion Price shall also be appropriately adjusted in the event that Maker issues shares of Common Stock (or issues securities, including warrants or similar rights, entitling holders to exercise, convert or exchange into, or otherwise subscribe for, shares of Common Stock) at a price per share less than the Current Market Price as of the date of such issuance, as follows: the new Conversion Price shall be reduced to equal (x) the prevailing Conversion Price (i.e., prior to any adjustment hereunder) multiplied by (y) the quotient obtained by dividing (a) the Market Value Share Number by (b) the total number of shares of Common Stock that would be outstanding after giving effect to the exercise, conversion or exchange of any rights or other derivative Company securities outstanding (determined pro forma for the applicable issuance giving rise to the adjustment in the Conversion Price hereunder). For purposes of the foregoing, the “Market Value Share Number” shall equal the sum of (i) the total number of shares of Common Stock that would be outstanding after giving effect to the exercise, conversion or exchange of any rights or other derivative Company securities outstanding (determined prior to the applicable issuance giving rise to the adjustment in the Conversion Price) plus (ii) the quotient obtained by dividing (A) the aggregate consideration received by the Company in the applicable issuance (or, in the case of the issuance of any rights or other derivative Company securities giving rise to the adjustment in the Conversion Price hereunder, such aggregate consideration to be received upon the exercise, conversion or exchange of any such rights or derivative Company securities) by (B) the Current Market Price. Notwithstanding the foregoing, there shall be no adjustment in the Conversion Price pursuant to this Section 3(b) in connection with shares of Common Stock (or issues of securities, including warrants or similar rights, entitling holders to exercise, convert or exchange into, or otherwise subscribe for, shares of Common Stock: (i) issuable or issued to employees, consultants or directors of the Maker (or any subsidiary thereof) in an aggregate amount representing not more than 40% of the shares of Common Stock outstanding on the date hereof and pursuant to a stock option plan or other equity incentive plan approved by the Board of Directors of Maker or (ii) issuable or issued in connection with bona fide acquisitions, mergers, strategic transactions, joint ventures or similar transactions, the terms of which are approved by the Board of Directors of Maker.

(c) In case of a Change of Control, instead of receiving shares of Maker’s Common Stock upon conversion of this Note, Payee shall have the right thereafter to receive the kind and amount of shares of stock and other securities, cash and property which the Payee would have owned or have been entitled to receive immediately after such Change of Control had the same portion of this Note been converted immediately prior to the effective date of such Change of Control and, in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section with respect to the rights and interests thereafter of the Payee, to the end that the provisions set forth in this Section shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of

stock and other securities, cash and property thereafter deliverable in connection with this Note. The provisions of this subsection shall similarly apply to successive Changes of Control.

(d) “Change of Control” means that the Maker shall, directly or indirectly, in one or more related transactions, (i) consolidate or merge with or into (whether or not the Maker is the surviving corporation) another person, (ii) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of the Maker to another person, (iii) allow another person to make a purchase, tender or exchange offer that is accepted by the holders of more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the person or persons making or party to, or associated or affiliated with the persons making or party to, such purchase, tender or exchange offer), or (iv) consummate a stock purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization or spin-off) with another person whereby such other person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other person or other persons making or party to, or associated or affiliated with the other persons making or party to, such stock purchase agreement or other business combination); provided, however, that a transaction in which Newcastle Partners, L.P. or any of its affiliates is the acquiring party shall not be deemed to constitute a Change of Control.

(e) No fractional shares of Maker’s Common Stock shall be issued upon conversion of the Note. In lieu of any fractional shares to which Payee would otherwise be entitled, the Maker shall pay cash equal to the product of such fraction multiplied by the average of the closing prices of the Common Stock on the principal exchange on which the Common Stock is listed (or the exchange on which Maker’s Common Stock trades) for the five consecutive trading days immediately preceding the date of the conversion.

(f) In the event of an adjustment to the Conversion Price, the Maker shall promptly deliver to the Payee a certificate, signed by its Chief Financial Officer, setting forth the new Conversion Price and a calculation in reasonable detail of the adjustment to the Conversion Price.

(g) The Maker shall pay any and all taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of this Note; provided that the Maker shall not be required to pay any tax that may be payable in respect of any issuance of Common Stock to any person other than the Payee or with respect to any income tax due by the Payee with respect to such Common Stock.

(h) Notwithstanding anything to the contrary contained in this Note, in no event shall this Note be converted by Payee into a number of shares of Common Stock which, when added together with any other outstanding shares of Common Stock and any shares of Common Stock into which derivative securities of Maker are then convertible or exercisable, exceed the maximum number of authorized shares of Common Stock of Maker under its existing Certificate of Incorporation; provided that, following Maker’s 2008 Annual Meeting of Stockholders, if the convertibility of this Note would be limited in any respect by the foregoing restriction (assuming for this purpose that Payee then elected to convert the entire principal balance of the Note but without any obligation of Payee to actually convert all or any portion of

the Note), the interest rate on the Excess Outstanding Principal Balance for purposes of Section 1 shall be increased to the lesser of (i) 14% per annum or (ii) the highest lawful interest rate permitted by applicable law. For purposes the foregoing, the “Excess Outstanding Principal Balance” shall mean the principal balance of the Note, determined as of the first day of every calendar quarter, in excess of the Convertible Principal Balance, and “Convertible Principal Balance” means the principal balance of the Note, determined as of the first day of every calendar quarter, that converts into a number of shares of Common Stock which, when added together with any other then outstanding shares of Common Stock and any shares of Common Stock into which any then outstanding derivative securities of Maker (including but not limited to all options, warrants, convertible securities and other securities) are convertible or exercisable, results in the precise number of authorized shares of Common Stock of Maker. Maker agrees to seek an amendment to its Certificate of Incorporation at the 2008 Annual Meeting of Stockholders (and any subsequent meeting if necessary) to increase its authorized shares of Common Stock to permit the full convertibility of this Note such that the foregoing restriction would not apply.

4. Redemption Upon Change of Control. No sooner than 15 days nor later than 10 days prior to the consummation of a Change of Control, the Maker shall deliver written notice of such Change of Control to the Payee (a “Change of Control Notice”). At any time during the period beginning after the Payee’s receipt of a Change of Control Notice and ending on the day immediately preceding the consummation of such Change of Control, the Payee may require the Maker to redeem all or any portion of this Note by delivering written notice thereof (a “Change of Control Redemption Notice”) to the Maker, which Change of Control Redemption Notice shall indicate the portion of the outstanding principal amount of this Note that the Payee is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 4 shall be redeemed by the Maker at a price equal to 110% of the principal amount being redeemed, plus accrued but unpaid interest on such principal amount (the “Change of Control Redemption Price”). Redemptions required by this Section 4 shall be made on the date of the consummation of the Change of Control and shall have priority to payments to shareholders of the Maker in connection with such Change of Control. Notwithstanding anything to the contrary in this Section 4, until the Change of Control Redemption Price is paid in full, the principal amount submitted for redemption under this Section 4 (together with any accrued but unpaid interest thereon) may be converted, in whole or in part, by the Payee into Common Stock pursuant to Section 3. If the cash funds of Maker then legally available for payment of the Change of Control Redemption Price are insufficient to pay in full the Change of Control Redemption Price, those funds which are legally available will be used to redeem the maximum portion of this Note subject to redemption, with the remaining portion of the Note remaining outstanding and entitled to the rights and benefits provided for herein.

5. Conversion On Maturity Date. On the Maturity Date, in lieu of receiving the payment required by Section 2(b), the Payee may elect to have Maker issue to the Payee a certificate representing such number of shares of Common Stock as is equal to the quotient obtained by dividing the entire principal amount of this Note then outstanding, plus all accrued but unpaid interest thereon, by the Conversion Price in effect at such time, in full satisfaction of this Note (the “Maturity Date Conversion”). The applicable provisions of Section 3 shall apply with equal force to the Maturity Date Conversion. In the event that the Shareholder Approval

has not then been obtained, Payee may elect to receive both (1) such number of shares as the Maker shall be permitted to issue under exchange rules in the absence of a shareholder vote and (2) cash in lieu of any remaining principal balance.

6. Representations of the Obligors. In order to induce the Payee to enter into this Note, each Obligor makes the following representations and warranties to the Payee which shall be true, correct, and complete, in all material respects, as of the date hereof and such representations and warranties shall survive the execution and delivery of this Note:

13. Default.

(a) The Obligors shall fail to make any payment of principal (including, but not limited to, upon any conversion pursuant to Section 5 hereof or the maturity of the Note) and/or accrued but unpaid interest (at the applicable rate) on the Note when due and payable, and such failure, in the case of any interest payment, shall continue for a period of at least five business days.

(b) The Obligors shall fail to perform or observe any covenant or other agreement contained in any of Sections 11 and 12 of this Note or Section 6 of the Security Agreement;

(c) The Obligors shall be in material default of any term or provision of this Note (other than any such term that is the subject of another provision of this Section 13, in which event such other provision of this Section 13 shall govern), the Purchase Agreement, the Registration Rights Agreement (as that term is defined in the Purchase Agreement), the Security Agreement, the Senior Loan Agreement and the Waiver and Amendment Agreement, and such failure shall continue through 15 days after Payee gives written notice of such material default to Maker.

(d) Any representation or warranty of the Maker contained in this Note shall have been false in any material respect on the Closing Date.

(e) Maker or any of its subsidiaries shall (i)(A) fail to make any payment when due under the terms of any bond, debenture, note or other evidence of indebtedness, including the Senior Debt, to be paid by such Person (excluding this Note but including any other evidence of indebtedness of Maker or any of its subsidiaries to the Payee) and such failure shall continue beyond any period of grace provided with respect thereto, or (B) default in the observance or performance of any other agreement, term or condition contained in any such bond, debenture, note or other evidence of indebtedness, and (ii) in each case, the effect of such failure or default is to cause, or permit the holder or holders thereof to cause, indebtedness in an aggregate amount of one million dollars ($1,000,000) or more to become due prior to its stated date of maturity, unless such acceleration shall have been rescinded and such failure to pay cured within thirty (30) days from the date of such acceleration.

(f) A final judgment or order for the payment of money in excess of one million dollars ($1,000,000) (exclusive of amounts covered by insurance issued by an insurer not an affiliate of Maker) shall be rendered against the Maker or any of its subsidiaries and the same shall remain undischarged for a period of thirty (30) days during which execution shall not be effectively stayed, or any judgment, writ, assessment, warrant of attachment, or execution or similar process shall be issued or levied against a substantial part of the property of the Maker or any of its subsidiaries and such judgment, writ, or similar process shall not be released, stayed, vacated or otherwise dismissed within thirty (30) days after issue or levy.

(g) If any Obligor or any subsidiary of an Obligor is enjoined, restrained, or in any way prevented by court order from continuing to conduct all or any material part of its business affairs.

(h) If a binding arbitration or final judgment or order renders that (i) any Obligor is in default of the SkyTel Sale Agreements that causes an order for the payment of greater than five hundred thousand ($500,000), or (ii) any Obligor must pay an indemnity claim of greater than five hundred thousand ($500,000) under the SkyTel Sale Agreements, and such claim shall remain undischarged for a period of thirty (30) days.

(i) Any Liens of Payee in any of the assets of Maker or its subsidiaries shall cease to be or shall not be valid and perfected Liens or the Maker or any subsidiary shall assert that such Liens are not valid and perfected Liens.

(j) The Maker or any of its subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar federal, foreign or state law for the relief of debtors (collectively, “Bankruptcy Law”), (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a receiver, trustee, assignee, liquidator or similar official (a “Custodian”), (iv) makes a general assignment for the benefit of its creditors or (v) admits in writing that it is generally unable to pay its debts as they become due.

(k) A court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (i) is for relief against the Maker or any of its subsidiaries in an involuntary case, (ii) appoints a Custodian of the Maker or any of its subsidiaries or (iii) orders the liquidation of the Maker or any of its subsidiaries.

Without limiting the above, the Maker acknowledges that payments (including but not limited to upon conversion of this Note) on the various scheduled due dates are of essence and that any failure to timely make any applicable payment of the principal or interest (within any permitted grace period) permits Payee to declare this Note immediately due in cash in its entirety without any prior notice of any kind to Maker, except for the specific notices provided above. Upon the occurrence and during the continuance of an event of default, the interest rate under this Note shall be increased to the lesser of (a) sixteen percent (16%) or (b) the highest lawful interest rate permitted by applicable law. In the event that such event of default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the interest as calculated and unpaid at such increased rate during the continuance of such event of default shall continue to apply to the extent relating to the days after the occurrence of such event of default through and including the date of cure of such event of default.

14. Applicable Law; Forum. THE VALIDITY, CONSTRUCTION AND ENFORCEABILITY OF THIS NOTE SHALL BE GOVERNED BY THE INTERNAL LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO CONFLICT OF LAWS PRINCIPLES THEREOF. EACH OF PAYEE AND MAKER CONSENTS TO SUBMIT TO THE PERSONAL JURISDICTION OF ANY STATE OR FEDERAL COURT SITTING IN THE STATE OF TEXAS, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE, AGREES THAT ALL CLAIMS IN RESPECT OF THE ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT, AND AGREES NOT TO BRING ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE IN ANY OTHER COURT. EACH OF THE PARTIES TO THIS AGREEMENT AGREES NOT TO ASSERT IN ANY ACTION OR PROCEEDING ARISING OUT OF RELATING TO THIS NOTE THAT THE VENUE IS IMPROPER, AND WAIVES ANY DEFENSE OF INCONVENIENT FORUM TO THE MAINTENANCE OF ANY ACTION OR PROCEEDING SO BROUGHT AND WAIVES ANY BOND, SURETY OR OTHER SECURITY THAT MIGHT BE REQUIRED OF ANY OTHER PARTY WITH RESPECT THERETO.

15. Waivers. The Maker hereby waives presentment for payment, notice of dishonor, protest and notice of payment and all other demands and notices of any kind in connection with the enforcement of this Note. Any provision of this Note may be amended, waived or modified upon the written consent of Maker and Payee. No failure or delay on the part of the Payee 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 power, right or privilege.

16. Effect of Shareholder Vote. No term of this Note shall be modified or voided as a result of any vote of the Company’s shareholders (or failure to obtain any such vote) unless the approval of the Company’s shareholders is required by state law to make such term of this Note effective.

Payee does not agree or intend to contract for, charge, collect, take, reserve or receive any amount in the nature of interest or otherwise which would in any way or event (including demand, prepayment or acceleration) cause Payee to collect more on its loan that the maximum amount Payee would be permitted to charge or collect by federal law or the law of the State of Texas (as applicable). Any such excess interest shall instead of anything to the contrary, be applied first to reduce the outstanding principal balance of this Note, and when the principal balance has been paid in full, be refunded to Maker.

23. This Note is a replacement, consolidation, amendment and restatement of the amended and restated convertible promissory note by Maker to Payee dated March 12, 2007 in

the original principal amount of $10,000,000 (the “Prior Note”) and IS NOT A NOVATION. Maker shall also pay, and this Note shall also evidence, any and all unpaid interests on all outstanding principal pursuant to the Prior Note, and at the interest rate specified therein, for which this Note has been issued as replacement therefor. Payee confirms that the representations and warranties made in Section 4 of the Purchase Agreement are true and correct as of the date hereof with respect to this Note and the securities underlying this Note.
