6.1.1 At Lender’s option, any time on or before March 31, 2003, Lender may convert all or part of the outstanding Advances under the Note into shares of NextNet Series A Preferred Stock owned by Borrower, or if such Series A Preferred Stock has been converted into common stock of NextNet, such NextNet common stock. Initially, the conversion rate (the “NextNet Conversion Rate”) of such shares shall be the equivalent of one share of NextNet Series A Preferred Stock or three shares of Common Stock for each $6.00 of principal amount of the Note ($2.00 per common share equivalent), subject to adjustment as set forth herein. The NextNet Conversion Rate shall be adjusted prior to each conversion to equal the lowest per share common equivalent price for any sale by Borrower or NextNet subsequent to the date of this Agreement to a purchaser other than Lender or persons or entities associated or affiliated with Lender of NextNet securities at a common per share equivalent price of less than $2.00 prior to the time the notice of conversion is given, to the extent the aggregate amount of the transaction or transactions prior to the affected conversion exceed $100,000.00. Issuances of securities pursuant to employee stock options and benefit plans and the issuance of any security pursuant to an existing warrant or option shall not cause an adjustment. The NextNet Conversion Rate for a conversion of Advances pursuant to this Section 6.1.1 shall not be adjusted for sales made subsequent to the affected conversion.

6.1.2 In case NextNet shall at any time exchange as a whole, by subdivision or combination in any manner or by the making of a stock split or stock dividend, the number of common shares or Series A Preferred Shares then outstanding into a different number of shares, with or without par value, thereafter the number of common equivalent shares or Series A Preferred Shares into which the principal balance of the Note is convertible (calculated immediately prior to such change), shall be increased or decreased, as the case may be, in direct proportion to the increase or decrease in the number of common shares or Series A Preferred Shares of NextNet by reason of such change.

6.1.3 In case of any reclassification or change of outstanding common shares of NextNet (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision, combination or stock dividend as provided for in Section 6.1.2), or in case of any consolidation of NextNet with, or merger of the NextNet into, another corporation, or in case of any sale of all, or substantially all, of the property, assets, business and goodwill of NextNet as an entirety, the principal balance of the Note shall be convertible into the kind and amount of shares of stock and other securities and property receivable upon such reclassification, change, consolidation, merger or sale by a holder of a common share of NextNet, adjusted for the NextNet Conversion Rate in effect immediately prior to such reclassification, change, consolidation, merger or sale or any further adjustment pursuant to Section 6.1.2 above.

6.2 Zamba Conversion.

6.2.1 Provided that Lender had theretofore made all required Advances, and at Lender’s option any time on or before March 31, 2003, Lender may convert all

outstanding Advances under the Note into that number of Borrower’s shares of common capital stock sufficient to cause Lender to own 20% of all of Borrower’s issued and outstanding common stock immediately after such conversion. Such conversion may occur only if the following conditions are met: (i) Lender has disposed of its Metalclad Insulation Corporation operations and obligations in a manner that is satisfactory to the Board of Directors of Borrower in its reasonable discretion (which discretion may include an analysis of continuing contingent liabilities resulting from the ownership of such operations) and (ii) Lender has cash and reasonably liquid assets of $7,500,000, less all Advances made through the date of conversion, as determined by the Chief Financial Officer of Zamba, in his reasonable discretion.

In case of any reclassification or change of outstanding common shares of Borrower (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision, combination or stock dividend), or in case of any consolidation of Borrower with, or merger of Borrower into, another corporation, or in case of any sale of all, or substantially all, of the property, assets, business and goodwill of Borrower as an entirety, subject to the provisions set forth above in Section 6.2.1, the principal balance of the Note shall be convertible into the kind and amount of shares of stock and other securities and property receivable upon such reclassification, change, consolidation, merger or sale by a holder of a common share of Borrower.

6.3 Conversion Procedures.

6.3.1 Borrower shall on the date hereof deliver to Collateral Agent pursuant to the Pledge Agreement a stock certificate or certificates representing 833,333 shares of Series A Preferred Stock of NextNet, said certificate(s) to be duly endorsed in blank or accompanied by Assignment(s) Separate from Certificate(s) duly endorsed in blank. If Lender desires to convert the Note in accordance with the terms hereof, Lender shall surrender the Note to Collateral Agent, or, if the Note has been lost, stolen, destroyed or mutilated, then, in the case of loss, theft or destruction, Lender shall deliver to Collateral Agent an indemnity agreement reasonably satisfactory in form and substance to Borrower, or, in the case of mutilation, Lender shall surrender to Collateral Agent and cancel the Note.

If Lender elects to convert to Borrower shares, Borrower shall, subject to the provisions elsewhere set forth herein, issue and deliver or cause to be issued and delivered to Lender at its address set forth below a certificate or certificates for the number of Borrower’s common stock to which Lender shall be entitled upon such conversion (bearing such legends as are reasonably required by Borrower’s counsel). If Lender elects to convert to NextNet shares, the Collateral Agent shall deliver to NextNet’s transfer agent the NextNet certificate(s) duly endorsed or with appropriate Assignment(s) Separate From Certicates(s) with instructions to issue and deliver certificates for the appropriate number of NextNet shares to Lender and the balance of the shares to be issued in a certificate to Borrower, provided however, said certificate of Borrower is to be returned and held by Collateral Agent pursuant to the terms of the Pledge Agreement.

On April 1, 2003, the Collateral Agent shall return to Borrower all shares of Collateral except, and Collateral Agent shall retain, a certificate or certificates for 250,000 shares of Series A Preferred Stock On August 31, 2003, Collateral still in the possession of Collateral Agent shall be returned to Borrower.

6.3.2 No fractional shares shall be issued upon conversion of the Note. In lieu of Borrower issuing any fractional shares to Lender upon the conversion of the Note, Borrower shall pay or cause to be paid to Lender an amount equal to the product obtained by multiplying the applicable conversion rate by the fraction of a share not issued pursuant to the previous sentence. Upon conversion of the Note in full, Borrower shall be forever released from all its obligations and liabilities under the Note.

ARTICLE VII

7.2 Exchange Act Reports. Continue to timely file all reports required to be filed by it under and pursuant to the Exchange Act.

7.4 Taxes, Assessments and Charges. Promptly pay over to the appropriate authorities all sums for taxes deducted and withheld from wages as well as the employer’s contributions relating thereto and promptly pay all taxes, assessments and other governmental charges imposed upon or asserted against Borrower’s income, profits, properties and activities and all claims for labor, materials, supplies, rental charges or otherwise which are or might become a lien charged upon Borrower’s properties, unless the same are being contested in good faith by appropriate proceedings and adequate reserves shall have been established on Borrower’s books with respect hereto.

7.5 Existence. Preserve and maintain its corporate existence and good standing in the jurisdiction of its incorporation and continue in compliance in all material respects with all applicable statutes, laws, rules and regulations.

7.6 Conduct of Business. Continue to engage in a business of the same general type as that now being conducted by Borrower on the date of this Agreement, provided, however, that nothing contained in this Section shall prevent Borrower from discontinuing any part of the

business of Borrower, if the discontinuance is, in the opinion of the Board of Directors of Borrower, in the best interests of Borrower.

ARTICLE VIII

NEGATIVE COVENANTS

Borrower hereby covenants and agrees with Lender that so long as any amount shall remain unpaid on any indebtedness of Borrower to Lender or Lender has any obligation to make advances hereunder, Borrower will not, without the written consent of Lender, create, assume, incur or suffer to exist any pledge, mortgage, assignment or other lien or encumbrance of any kind, or upon any of the Collateral.

ARTICLE IX

EVENTS OF DEFAULT

9.1 Events of Default by Borrower. The occurrence of any one or more of the following events shall constitute an “Event of Default by Borrower:”

9.1.1 Failure of Borrower to make any payment when due of interest on the Note, provided that Borrower shall have fifteen (15) days from the date on which it receives written notice from Lender of any such nonpayment of interest to make such interest payment; or

9.1.2 Any material representation by Borrower herein is untrue as of the date made or Borrower defaults in the due performance and observance of any covenants in this Agreement and such default continues for a period of thirty (30) days after written notice from Lender.

9.1.3 On or prior to the Maturity Date, Borrower applies for, consents to, or acquiesces in the appointment of trustee or receiver of Borrower, or its property; or, in the absence of such application, consent or acquiescence, a trustee or receiver is appointed for Borrower, or for a substantial part of its property; or any bankruptcy, reorganization, debt arrangement or other proceedings under any bankruptcy or insolvency law is instituted by or against Borrower; or

9.1.4 On or prior to the Maturity Date, any dissolution or liquidation proceeding is instituted by or against Borrower; or

9.1.5 Judgments against Borrower for the payment of money totaling in excess of $10,000,000.00 shall be outstanding for a period of ninety (90) days without a stay of execution.

9.2 Lender’s Remedies. If any Event of Default by Borrower shall occur as a result of any of the events described in Section 9.1 above (taking into account the applicable cure period set forth above), any amounts then outstanding under the Note, including accrued interest, shall be converted into Borrower’s shares of NextNet Series A Preferred Stock at the conversion price of $3.00 per share ($1.00 per common share equivalent), unless at such time, there is also an Event of Default by Lender (as defined below), in which case all amounts then outstanding under the Note, including accrued interest, shall be converted into Borrower’s shares of NextNet Series

A Preferred Stock at the conversion price of $6.00 per share ($2.00 per common share equivalent), after either of which the obligations required in this Agreement or any other Loan Document to be performed by Borrower, other than to have registered in Lender’s name and to deliver to Lender those shares of NextNet Series A Preferred Stock which are transferable to Lender as a result of such Event of Default by Borrower or Lender’s exercise of the Option, shall automatically terminate and be of no further force or effect, provided that if an Event of Default by Borrower occurs prior to Lender’s making the Second or Third Advance, Lender shall not be required to make any such advance. Provided Lender receives NextNet Series A Preferred Stock in accordance with the foregoing remedy, such remedy shall be Lender’s sole remedy for an Event of Default by Borrower described in Sections 9.1.1, 9.1.3, 9.1.4 and 9.1.5.

9.3 Event of Default by Lender. For the purposes hereof, any failure by Lender to make any Advance if and when due shall constitute an Event of Default by Lender.

Exhibit 10.02

ESCROW AND PLEDGE SECURITY AGREEMENT

ESCROW AND PLEDGE SECURITY AGREEMENT dated as of November 4, 2002 among Zamba Corporation, a Delaware corporation (“Debtor”), Entrx Corporation, a Delaware corporation (“Secured Party”) and Wells Fargo Bank Minnesota, N.A., as collateral agent (“Collateral Agent”).

Debtor hereby grants to Secured Party a Security Interest in the following described property (hereinafter referred to as “Collateral”):

833,333 shares (the “Shares”) of Series A Preferred Stock of NextNet Wireless, Inc., a Delaware corporation, and any cash, additional shares, or securities or other property at any time and from time to time receivable or distributable in respect of, in exchange for, in addition to, or in substitution of, such securities, including all dividends, stock splits, stock dividends, and distributions on or other rights in connection with such property,

to secure obligations to the Secured Party pursuant to the Loan Agreement and that Secured Convertible Promissory Note in the amount of $2,500,000 (including delivery of Shares upon conversion of the Secured Convertible Promissory Note into Shares) of even date herewith made by Debtor payable to Secured Party, and all renewals, replacement, extensions, amendments and refinancings thereof (hereinafter called “Secured Obligations”).

The parties hereto further agree as follows:

1. Debtor hereby represents, warrants and agrees that it has title to the Collateral, free of all liens and encumbrances, except the Security Interest created hereby, and has full power and authority to execute this Escrow and Pledge Security Agreement, to perform Debtor’s obligations hereunder, under the Loan Agreement and the Secured Convertible Promissory Note and to subject the Collateral to the Security Interest created hereby. There is no financing statement, security agreement, pledge agreement, control agreement, option agreement, right of refusal to purchase agreement or other agreement relating to the Collateral which grants any right in or restriction upon the Collateral. Debtor will not assign, pledge, or otherwise transfer any interest in the Collateral to any party other than the Secured Party.

2. The Collateral Agent shall exercise reasonable care in the custody and preservation of the Collateral.

3. So long as no Event of Default by Borrower under the Loan Agreement shall have occurred or no Delivery Notice (as hereinafter defined) shall have been received by Collateral Agent, Debtor shall be entitled to exercise any and all voting or consensual rights and powers accruing to ownership of the Collateral for any purpose not inconsistent with the terms of this Escrow and Pledge Security Agreement or any agreement giving rise to any of the Secured Obligations; provided however, any and all cash dividends paid on the Collateral, and any and all stock or liquidating dividends, other distributions in property, return of capital or other distributions made on or in respect of Collateral shall be and become part of the Collateral pledged hereunder and, if received by the Debtor, shall forthwith be delivered to the Collateral

Agent to be held as Collateral subject to the terms of this Escrow and Pledge Security Agreement.

4. No delay or failure by the Secured Party in the exercise of any right or remedy shall constitute a waiver thereof, and no single or partial exercise by the Secured Party of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy.

5. Debtor shall contemporaneously deliver to the Collateral Agent, and grants Secured Party a security interest in, all certificates, duly endorsed in blank or accompanied by a duly executed Assignment Separate From Certificate for each such certificate, representing the Collateral and any other property hereafter acquired by Debtor which represents Collateral, to be held by the Collateral Agent as Collateral under the terms of this Agreement.

6. Debtor and Secured Party hereby appoint as Collateral Agent to hold and possess the Collateral subject to the terms hereof and Debtor is delivering the Shares to the Collateral Agent on the date hereof, to be held pursuant to the terms of this Agreement.

7. Secured Party may give the Collateral Agent and Debtor notice of conversion of the Secured Convertible Promissory Note into Shares pursuant to the terms of Article VI or Section 9.2 of the Loan Agreement (the “Delivery Notice”). The Delivery Notice shall state the number of Shares to be delivered to Secured Party pursuant to the conversion provisions. Within 5 Business Days (as defined in the Loan Agreement) after receipt of a Delivery Notice, the Collateral Agent shall, unless Debtor prior thereto obtains a court order restraining such delivery, deliver to Secured Party certificates duly endorsed, or certificates with Assignments Separate From Certificates duly endorsed, to Secured Party representing at a minimum the Shares requested in the Delivery Notice. If the certificates delivered to Secured Party represent a number of Shares exceeding the number of Shares stated in the Delivery Notice, Secured Party shall upon submission of the certificates to the appropriate share transfer agent direct that the excess Shares be issued in the name of Debtor but returned directly the Collateral Agent, to be retained by Collateral Agent pursuant to the terms of this Agreement.. Collateral Agent shall return Collateral remaining in Collateral Agent’s possession to Debtor when notified in writing by the Secured Party and the Debtor the Secured Obligations have been paid in full. Without limiting the foregoing, all Collateral remaining in the possession of Collateral Agent on April 1, 2003 in excess of 250,000 shares of Series A Preferred Stock shall be released and returned to Debtor on April 1, 2003, and any Collateral remaining in the possession of the Collateral Agent on August 31, 2003, shall be returned to Debtor unless prior to either date Lender obtains a court order restraining such delivery.

8. The duties and responsibilities of the Collateral Agent hereunder shall be determined solely by the express provisions of this Agreement, and no other or further duties or responsibilities shall be implied. The Collateral Agent shall not have any liability under, nor duty to inquire into, the terms and provisions of any agreement or instructions, other than as outlined in this Agreement.

9. The Collateral Agent may rely upon and shall be protected in acting or refraining from acting upon any written notice, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties. The Collateral Agent shall be under no duty to inquire into or investigate the validity, accuracy or

content of any such document. The Collateral Agent shall have no duty to solicit any items that may be due it hereunder.

10. The Collateral Agent shall not be liable for any action taken or omitted by it in good faith unless a court of competent jurisdiction determines that the Collateral Agent’s gross negligence, bad faith or willful misconduct was the primary cause of any loss to any other party hereto. The Collateral Agent may consult with counsel of its own choice and shall have full and complete authorization and protection for any action taken or omitted by it hereunder in good faith and in accordance with the opinion of such counsel.

11. The Debtor and the Secured Party shall indemnify the Collateral Agent for, and hold it harmless against, any loss, liability or expense arising out of, or in connection with, this Agreement and carrying out its duties hereunder, including the costs and expenses of defending itself against any claim of liability, except in those cases where the Collateral Agent has been guilty of negligence, bad faith or willful misconduct.

12. In the event that the Collateral Agent is uncertain as to its duties or rights hereunder or receives instructions, claims or demands from any party hereto that, in its opinion, conflict with any of the provisions of this Agreement (i) the Collateral Agent shall be entitled to refrain from taking any action and may withhold delivery of the Collateral until such uncertainty is resolved or the conflicting instruction, claim or demand is withdrawn, and its sole obligation shall be to keep safely the Collateral in escrow until the Collateral Agent is directed otherwise by a final order or judgment of a court of competent jurisdiction, and (ii) the Collateral Agent shall have the right, but not the obligation, to institute a petition for interpleader in any court of competent jurisdiction to determine the rights of the parties hereto. Should any such petition for interpleader be instituted or should the Collateral Agent be threatened with litigation or become a party to litigation or binding arbitration in any manner whatsoever in connection with this Agreement or the Collateral, the Collateral Agent shall be entitled to indemnification as set forth in Section 11 hereof.

13. The fees of the Collateral Agent are set forth in Schedule 1 hereto. All fees of the Collateral Agent for establishing and holding the Collateral shall be paid one-half by the Debtor and one-half by the Secured Party.

14. In the event the Collateral Agent becomes unavailable or unwilling to continue in its appointed capacity hereunder, the Collateral Agent may resign and be discharged from its duties or obligations hereunder by giving notice of resignation to each of the parties hereto, specifying a date not less than 60 days following such notice date when such resignation will take effect; provided, however, that such resignation shall in no event take effect before the successor to the Collateral Agent shall have been appointed pursuant to this Section. The Secured Party shall appoint a successor to the Collateral Agent with the consent of the Secured Party, which consent shall not be unreasonably withheld. The Collateral Agent shall promptly transfer the Collateral to such designated successor.

15. Any corporation or other entity into which the Collateral Agent in its individual capacity may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Collateral Agent in its individual capacity shall be a party, or any corporation or other entity to which

substantially all of the corporate trust business of the Collateral Agent in its individual capacity may be transferred, shall be the Collateral Agent under this Agreement without further act.
