All claims or demands for indemnification under this ARTICLE 7 ("Claims") shall be asserted and resolved as follows: (a) In the event that any Person entitled to indemnification hereunder (the "Indemnified Party") has a Claim against any party obligated to provide indemnification pursuant to Section 7.1 or 7.2 hereof (the "Indemnifying Party") which does not involve a Claim being sought to be collected by a third party, the Indemnified Party shall with reasonable promptness send a Claim Notice with respect to such Claim to each Indemnifying Party. If the 47 Indemnifying Party does not notify the Indemnified Party within fifteen (15) days from receipt of the Claim Notice (the "Notice Period") that the Indemnifying Party disputes such Claim, the amount of such Claim shall be conclusively deemed a liability of the Indemnifying Party hereunder. In case an objection is made in writing in accordance with this Section 7.4(a), the Indemnified Party shall have fifteen (15) days to respond in a written statement to the objection. If after such fifteen (15) day period there remains a dispute as to any Claims, the parties shall attempt in good faith for fifteen (15) days to agree upon the rights of the respective parties with respect to each of such Claims. If the parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties. (b) In the event that any Claim for which the Indemnifying Party would be liable to an Indemnified Party hereunder is asserted against an Indemnified Party by a third party, the Indemnified Party shall with reasonable promptness notify the Indemnifying Party of such Claim, by delivery of a Claim Notice. The Indemnifying Party shall, within the Notice Period, notify the Indemnified Party (i) whether or not such Indemnifying Party disputes the liability to the Indemnified Party hereunder with respect to such Claim and (ii) if such Indemnifying Party does not dispute such liability, whether or not the Indemnifying Party desires, at the sole cost and expense of the Indemnifying Party, to defend against such Claim, provided that such Indemnifying Party is hereby authorized (but not obligated) prior to and during the Notice Period to file any motion, answer or other pleading and to take any other action which the Indemnifying Party shall deem necessary or appropriate to protect the Indemnifying Party's interests. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that the Indemnifying Party does not dispute the Indemnifying Party's obligation to indemnify hereunder and desires to defend the Indemnified Party against such Claim and except as hereinafter provided, such Indemnifying Party shall have the right to defend by appropriate proceedings, which proceedings shall be promptly settled or prosecuted by such party to a final conclusion, provided that, unless the Indemnified Party otherwise agrees in writing, the Indemnifying Party may not settle any matter (in whole or in part) unless such settlement (A) includes a complete and unconditional release of the Indemnified Party, and (B) excludes any injunctive or non-monetary relief applicable to the Indemnified Party or any of its subsidiaries or Affiliates. If the Indemnified Party desires to participate in, but not control, any such defense or settlement, the Indemnified Party may do so at its sole cost and expense. If the Indemnifying Party elects not to defend the Indemnified Party against such Claim, whether by failure of such party to give the Indemnified Party timely notice as provided above or otherwise, then the Indemnified Party, without waiving any rights against such party, may settle or defend against any such Claim in the Indemnified Party's sole discretion and the Indemnified Party shall be entitled to recover from the Indemnifying Party the amount of any settlement or judgment and, on an ongoing basis, all Damages of the Indemnified Party with respect thereto, including interest from the date such Damages were incurred. All reasonable costs and expenses incurred by the Indemnified Party in so defending a Claim shall constitute Damages. (c) If at any time any Claim described in Section 7.4(b) seeks material prospective relief which is reasonably likely to have: (i) in the case of the Seller as the Indemnified Party, a materially adverse effect on the assets, liabilities, financial condition, results of operations or business prospects of the Seller Services, HM5000 Retained Business, and (ii) in the case of the Buyer as the Indemnified Party, a materially adverse effect on the assets, liabilities, financial condition, results of operations or business prospects of the Business, the 48 Indemnified Party shall have the right to control or assume (as the case may be) the defense of any such Claim and the amount of any judgment or settlement and the reasonable costs and expenses of defense shall be included as part of the indemnification obligations of the Indemnifying Party hereunder. If the Indemnified Party should elect to exercise such right, the Indemnifying Party shall have the right to participate in, but not control, the defense of such claim or demand at the sole cost and expense of the Indemnifying Party. (d) Nothing herein shall be deemed to prevent the Indemnified Party from making a claim, and an Indemnified Party may make a claim hereunder, for potential or contingent claims or demands provided the Claim Notice sets forth the specific basis for any such potential or contingent claim or demand to the extent then feasible and to the extent such a claim or demand is reasonably likely to be made. (e) The Indemnified Party's failure to give reasonably prompt notice as required by this Section 7.4 of any actual, threatened or possible Claim which may give rise to a right of indemnification hereunder shall not relieve the Indemnifying Party of any liability which the Indemnifying Party may have to the Indemnified Party except to the extent the failure to give such notice materially and adversely prejudiced the Indemnifying Party. (f) The parties will make appropriate adjustments for any Tax benefits, Tax detriments or insurance proceeds in determining the amount of any indemnification obligation under Section 7.1 or 7.2. 7.5 Remedies. The remedies set forth in this ARTICLE 7 are cumulative and shall not be construed to restrict or otherwise affect any other remedies that may be available to the Indemnified Parties under any other agreement or pursuant to statutory or common law. 7.6 Right to Setoff. Notwithstanding anything to the contrary herein, the Buyer shall have the right, but not the obligation, to setoff against the following portion of the Purchase Price: (i) $1,000,000 held in escrow pursuant to the Escrow Agreement, (ii) $2,000,000 of the $4,000,000 due and payable sixty (60) days after Closing pursuant to the Note; and (iii) $4,000,000 due and payable 90 days after Closing pursuant to the Note, in whole or in part, for any claims pursuant to this ARTICLE 7 that in Buyer's good faith and reasonable estimate could be expected to result in Damages to the Business in excess of one million United States dollars ($1,000,000). Any amounts set off by Buyer pursuant to this Section 7.6 that are subsequently delivered to Seller shall be paid in cash. Notwithstanding anything to the contrary set forth in this Agreement and all agreements and instruments delivered in connection herewith, the Buyer shall not be entitled to any setoff unless the Buyer provides prior written notice of its intent to setoff to the Seller, which notice shall be effective when sent and state in reasonable detail the Buyer's good faith basis for, and estimate of, the aggregate amount of its total claim for setoff. The Buyer agrees to consult with the Seller for a period of not less than ten (10) days after the delivery of such notice by the Buyer regarding the proposed setoff provided, however, that Buyer shall have the right to withhold payment hereunder during any such period of consultation. The reasonable exercise of such right of setoff by the Buyer in good faith, whether or not ultimately determined to be justified, will not constitute a breach or event of default under the Note or applicable agreement. Neither the exercise of, nor the failure to exercise such right of setoff, will 49 constitute an election of remedies or limit the Buyer in any manner in the enforcement of any other remedies that may be available to it. 7.7 Basket and Cap for Damages. (a) Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the Seller shall not have any liability under Section 7.1 unless and until the aggregate Damages of the Buyer Indemnified Parties exceed one hundred fifty thousand United States dollars ($150,000) (the "Threshold") at which time the Seller will be obligated to indemnify the Buyer Indemnified Parties with respect to the aggregate amount of all such Damages; provided, however, that the Threshold shall not apply to (i) any proration payment pursuant to Section 1.6 or purchase price adjustment pursuant to Section 1.7; or (ii) any Damages arising out of any misrepresentation, breach or inaccuracy of any representation or warranty by Seller constituting a knowing and intentional misrepresentation by Seller. Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the aggregate amount recoverable from the Seller in satisfaction of claims for payment of Damages under this Agreement or any other agreement delivered in connection with the transactions contemplated hereby, shall not exceed fifteen million United States dollars ($15,000,000). (b) Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the Buyer shall not have any liability under Section 7.2(a)(i) unless and until the aggregate Damages of the Seller Indemnified Parties exceed the Threshold at which time the Buyer will be obligated to indemnify the Seller Indemnified Parties with respect to the aggregate amount of all such Damages; provided, however, the Threshold shall not apply to (i) any proration payment pursuant to Section 1.6 or purchase price adjustment pursuant to Section 1.7, or (ii) any Damages arising out of any misrepresentation, breach or inaccuracy of any representation or warranty by Buyer constituting a knowing and intentional misrepresentation by Buyer. Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the aggregate amount recoverable from the Buyer in satisfaction of claims for payment of Damages under this Agreement or any other agreement delivered in connection with the transactions contemplated hereby, shall not exceed fifteen million United States dollars ($15,000,000).

Because, subject to the limitations set forth above, all rights under the HM5000 Contracts have been assigned to Buyer pursuant to the Purchase Agreement, subject to Section 4.1(c), Seller shall have no right to terminate or modify the HM5000 Contracts or to discontinue provision of the HM5000 Airtime Services, except as directed by Buyer in accordance with the foregoing. 1.2 Consideration for Provision of HM5000 Airtime Services. In exchange for Seller's promise to Buyer to provide the HM5000 Airtime Services to the HM5000 Customers in accordance with Section 1.1, for so long as Seller provides such HM5000 Airtime Services pursuant to Section 1.1, except as otherwise provided in paragraph (g), Buyer hereby agrees to pay Seller Seller's actual costs of providing the HM5000 Airtime Services to the extent set forth below: (a) Third Party Cellular Services. ----------------------------- (i) Seller is charged for the HM5000 Airtime Services by Seller's cellular carriers (the "Cellular Carriers"), who charge Seller per minute of HM5000 Airtime Services.

Seller shall inform Buyer of any such overcharge, keep Buyer apprised of efforts to obtain a refund of such overcharge, and promptly remit any such refund received to Buyer. (b) TSI Services.

In exchange for the foregoing payment, Seller agrees to maintain and technically support the NSC with same level of care as Seller used to perform these activities prior to Closing, but in no event less than a 3 commercially reasonable standard of care.

The foregoing operation costs are itemized in Schedule 9.2(a) and shall not be modified without the consent of both parties. Buyer may terminate any or all of the network, phone system or ACD system sharing arrangements upon thirty (30) days notice to Seller, in which event Buyer shall no longer pay any portion of the applicable operation costs. 15 (b) General Office Systems. Buyer employees working in the Office Space or the Warehouse Space shall retain access to Seller's general office software (e.g., e-mail, print functionality, word processing, etc.) and to Seller's voicemail system until such time as Buyer has established connectivity between the Office Space and Warehouse Space and Buyer's network and has provided Buyer employees located at the Office Space and Warehouse Space access to the equivalent Buyer office software on Buyer's network.

All claims or demands for indemnification under this ARTICLE 7 ("Claims") shall be asserted and resolved as follows: (a) In the event that any Person entitled to indemnification hereunder (the "Indemnified Party") has a Claim against any party obligated to provide indemnification pursuant to Section 7.1 or 7.2 hereof (the "Indemnifying Party") which does not involve a Claim being sought to be collected by a third party, the Indemnified Party shall with reasonable promptness send a Claim Notice with respect to such Claim to each Indemnifying Party. If the Indemnifying Party does not notify the Indemnified Party within fifteen (15) days from receipt of the Claim Notice (the "Notice Period") that the Indemnifying Party disputes such Claim, the amount of such Claim shall be conclusively deemed a liability of the Indemnifying Party hereunder. In case an objection is made in writing in accordance with this Section 7.4(a), the Indemnified Party shall have fifteen (15) days to respond in a written statement to the objection. If after such fifteen (15) day period there remains a dispute as to any Claims, the parties shall attempt in good faith for fifteen (15) days to agree upon the rights of the respective parties with respect to each of such Claims. If the parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties. (b) In the event that any Claim for which the Indemnifying Party would be liable to an Indemnified Party hereunder is asserted against an Indemnified Party by a third party, the Indemnified Party shall with reasonable promptness notify the Indemnifying Party of such Claim, by delivery of a Claim Notice. The Indemnifying Party shall, within the Notice Period, notify the Indemnified Party (i) whether or not such Indemnifying Party disputes the liability to the Indemnified Party hereunder with respect to such Claim and (ii) if such Indemnifying Party does not dispute such liability, whether or not the Indemnifying Party desires, at the sole cost and expense of the Indemnifying Party, to defend against such Claim, provided that such Indemnifying Party is hereby authorized (but not obligated) prior to and during the Notice Period to file any motion, answer or other pleading and to take any other action which the Indemnifying Party shall deem necessary or appropriate to protect the Indemnifying Party's interests. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that the Indemnifying Party does not dispute the Indemnifying Party's obligation to indemnify hereunder and desires to defend the Indemnified Party against such Claim and except as hereinafter provided, such Indemnifying Party shall have the right to defend by appropriate proceedings, which proceedings shall be promptly settled or prosecuted by such party to a final conclusion, provided that, unless the Indemnified Party otherwise agrees in writing, the Indemnifying Party may not settle any matter (in whole or in part) unless such settlement (A) includes a complete and unconditional release of the Indemnified Party, and (B) excludes any injunctive or non-monetary relief applicable to the Indemnified Party or any of its subsidiaries or Affiliates. If the Indemnified Party desires to participate in, but not control, any such defense or settlement, the Indemnified Party may do so at its sole cost and expense. If the Indemnifying Party elects not to defend the Indemnified Party against such Claim, whether by failure of such party to give the Indemnified Party timely notice as provided above or otherwise, then the Indemnified Party, without waiving any rights against such party, may settle or defend against any such Claim in the Indemnified Party's sole discretion and the Indemnified Party shall be entitled to recover from the Indemnifying Party the amount of any settlement or judgment and, on an ongoing basis, all Damages of the Indemnified Party with respect thereto, including interest from the date such Damages were incurred. All reasonable costs and expenses incurred by the Indemnified Party in so defending a Claim shall constitute Damages. (c) If at any time any Claim described in Section 7.4(b) seeks material prospective relief which is reasonably likely to have: (i) in the case of the Seller as the Indemnified Party, a materially adverse effect on the assets, liabilities, financial condition, results of operations or business prospects of the Seller Services, HM5000 Retained Business, and (ii) in the case of the Buyer as the Indemnified Party, a materially adverse effect on the assets, liabilities, financial condition, results of operations or business prospects of the Business, the Indemnified Party shall have the right to control or assume (as the case may be) the defense of any such Claim and the amount of any judgment or settlement and the reasonable costs and expenses of defense shall be included as part of the indemnification obligations of the Indemnifying Party hereunder. If the Indemnified Party should elect to exercise such right, the Indemnifying Party shall have the right to participate in, but not control, the defense of such claim or demand at the sole cost and expense of the Indemnifying Party. (d) Nothing herein shall be deemed to prevent the Indemnified Party from making a claim, and an Indemnified Party may make a claim hereunder, for potential or contingent claims or demands provided the Claim Notice sets forth the specific basis for any such potential or contingent claim or demand to the extent then feasible and to the extent such a claim or demand is reasonably likely to be made. (e) The Indemnified Party's failure to give reasonably prompt notice as required by this Section 7.4 of any actual, threatened or possible Claim which may give rise to a right of indemnification hereunder shall not relieve the Indemnifying Party of any liability which the Indemnifying Party may have to the Indemnified Party except to the extent the failure to give such notice materially and adversely prejudiced the Indemnifying Party. (f) The parties will make appropriate adjustments for any Tax benefits, Tax detriments or insurance proceeds in determining the amount of any indemnification obligation under Section 7.1 or 7.2. 7.5 Remedies. The remedies set forth in this ARTICLE 7 are cumulative and shall not be construed to restrict or otherwise affect any other remedies that may be available to the Indemnified Parties under any other agreement or pursuant to statutory or common law. 7.6 Right to Setoff. Notwithstanding anything to the contrary herein, the Buyer shall have the right, but not the obligation, to setoff against the following portion of the Purchase Price: (i) $1,000,000 held in escrow pursuant to the Escrow Agreement, (ii) $2,000,000 of the $4,000,000 due and payable sixty (60) days after Closing pursuant to the Note; and (iii) $4,000,000 due and payable 90 days after Closing pursuant to the Note, in whole or in part, for any claims pursuant to this ARTICLE 7 that in Buyer's good faith and reasonable estimate could be expected to result in Damages to the Business in excess of one million United States dollars ($1,000,000). Any amounts set off by Buyer pursuant to this Section 7.6 that are subsequently delivered to Seller shall be paid in cash. Notwithstanding anything to the contrary set forth in this Agreement and all agreements and instruments delivered in connection herewith, the Buyer shall not be entitled to any setoff unless the Buyer provides prior written notice of its intent to setoff to the Seller, which notice shall be effective when sent and state in reasonable detail the Buyer's good faith basis for, and estimate of, the aggregate amount of its total claim for setoff. The Buyer agrees to consult with the Seller for a period of not less than ten (10) days after the delivery of such notice by the Buyer regarding the proposed setoff provided, however, that Buyer shall have the right to withhold payment hereunder during any such period of consultation. The reasonable exercise of such right of setoff by the Buyer in good faith, whether or not ultimately determined to be justified, will not constitute a breach or event of default under the Note or applicable agreement. Neither the exercise of, nor the failure to exercise such right of setoff, will constitute an election of remedies or limit the Buyer in any manner in the enforcement of any other remedies that may be available to it. 7.7 Basket and Cap for Damages. -------------------------- (a) Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the Seller shall not have any liability under Section 7.1 unless and until the aggregate Damages of the Buyer Indemnified Parties exceed one hundred fifty thousand United States dollars ($150,000) (the "Threshold") at which time the Seller will be obligated to indemnify the Buyer Indemnified Parties with respect to the aggregate amount of all such Damages; provided, however, that the Threshold shall not apply to (i) any proration payment pursuant to Section 1.6 or purchase price adjustment pursuant to Section 1.7; or (ii) any Damages arising out of any misrepresentation, breach or inaccuracy of any representation or warranty by Seller constituting a knowing and intentional misrepresentation by Seller. Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the aggregate amount recoverable from the Seller in satisfaction of claims for payment of Damages under this Agreement or any other agreement delivered in connection with the transactions contemplated hereby, shall not exceed fifteen million United States dollars ($15,000,000). (b) Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the Buyer shall not have any liability under Section 7.2(a)(i) unless and until the aggregate Damages of the Seller Indemnified Parties exceed the Threshold at which time the Buyer will be obligated to indemnify the Seller Indemnified Parties with respect to the aggregate amount of all such Damages; provided, however, the Threshold shall not apply to (i) any proration payment pursuant to Section 1.6 or purchase price adjustment pursuant to Section 1.7, or (ii) any Damages arising out of any misrepresentation, breach or inaccuracy of any representation or warranty by Buyer constituting a knowing and intentional misrepresentation by Buyer. Notwithstanding anything to the contrary contained in ARTICLE 7 or any other provision of this Agreement, the aggregate amount recoverable from the Buyer in satisfaction of claims for payment of Damages under this Agreement or any other agreement delivered in connection with the transactions contemplated hereby, shall not exceed fifteen million United States dollars ($15,000,000).

Interest shall accrue on the unpaid Principal Sum at an annual rate equal to the Prime Rate as charged by the Bank of America, N.A. plus one percent (1%) on the date hereof. Interest shall be calculated on a 365 or, if applicable, a 366 day year. 3. Conversion. ---------- (a) Voluntary Conversion. At any time, subject to Section 3(c), the Maker shall have the option to convert, in whole or in part, any unpaid Principal Sum and any accrued but unpaid interest under this Note in accordance with Section 3(b) hereof, into fully paid shares of Series A Preferred Stock of the Maker at $5,000.00 per share (the "Conversion Rights"). Notwithstanding anything to the contrary contained herein, Maker shall not be entitled to exercise its Conversion Rights if: (i) there has occurred an Event of Default (as defined in Section 4 of this Note); (ii) there is a Triggering Event as defined in the Certificate of Designation for the Series A Preferred Stock (the "Certificate"); or (iii) there has occurred an event described in Section 3(c) hereof, but only to the extent provided in Section 3(c). (b) Conversion Procedure. -------------------- (i) Notice of Conversion Pursuant to Section 3(a). Before the Maker shall be entitled to convert this Note into shares of Series A Preferred Stock pursuant to Section 3(a) on each Payment Date, it shall deliver to the Payee a duly executed Notice of Conversion (a form of which is attached hereto) informing the Payee of the Maker's election to convert this Note pursuant to Section 3(a). The Maker shall within three (3) Business Days, issue and deliver at such office to the Payee of this Note a certificate or certificates for the number of shares of Series A Preferred Stock to which the Payee of this Note shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date the Notice of Conversion is delivered to the Payee, and the person or persons entitled to receive the shares of Series A Preferred Stock issuable upon such conversion shall be treated for all purposes as the registered Payee or Payees of such shares of Series A Preferred Stock as of such date. Notwithstanding the foregoing, if the Maker elects to convert less than the entire amount of the Principal Sum and accrued and unpaid interest under this Note into shares of Series A Preferred Stock pursuant to Section 3(a) (such amount converted being the "Partial Conversion Amount"), the amount of the Principal Sum and accrued and unpaid interest hereunder shall be reduced by such Partial Conversion Amount. (ii) Delivery of Share Certificates. Within three (3) Business Days of the conversion of this Note, the Maker at its expense will issue and deliver to the Payee of this Note a certificate or certificates of the number of shares of Series A Preferred Stock issuable upon such conversion of this Note. (iii) Mechanics and Effect of Conversion. No fractional shares of equity securities shall be issued upon conversion of this Note. In lieu of the Maker issuing any fractional shares to the Payee upon the conversion in whole of this Note, the Maker shall pay to the Payee the amount of outstanding Principal Sum that is not so converted, such payment to be in the form as provided below. Where conversion is in part only, the relevant whole number of shares shall be issued and all remaining Principal Sum (including any amount which would otherwise give rise to a fractional entitlement to shares) shall remain outstanding. (iv) Reservation of Shares Issuable Upon Conversion. The Maker shall at all times keep available out of its authorized but unissued shares of Series A Preferred Stock solely for the purpose of effecting the conversion of this Note, such number of shares of Series A Preferred Stock (and shares of the Maker's common stock (the "Common Stock") for issuance upon conversion of such shares of Series A Preferred Stock) as shall from time to time be sufficient to effect the conversion of this Note in the full Principal Sum plus accrued and unpaid interest; and if at any time the number of authorized but unissued shares of Series A Preferred Stock (and shares of Common Stock for issuance on conversion of such shares of Series A Preferred Stock) shall not be sufficient to effect the conversion of the entire outstanding Principal Sum plus accrued and unpaid interest, in addition to such other remedies as shall be available to the Payee, the Maker will use its best efforts to take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of shares of Series A Preferred Stock (and shares of Common Stock for issuance on conversion of such shares of Series A Preferred Stock) to such number of shares as shall be sufficient for such purposes. (v) Adjustment for Share Splits, etc. The number of shares of Series A Preferred Stock to which the Payee is entitled under Section 3(a) shall be adjusted proportionately to take account of subdivisions, combinations, scrip dividends and the like effected in respect of the Maker's existing shares of Series A Preferred Stock after the date hereof. (c) Further Conversion Limitation. The Maker shall be required to repay that portion of the Principal Sum due on a particular Payment Date (and accrued and unpaid interest on the final Payment Date) in cash (and may not exercise its Conversion Rights to make payments hereunder in shares of Series A Preferred Stock) on such Payment Date if at any time during the Applicable Trading Period (as defined in Section 20), the closing bid price of Maker's Common Stock shall be less than $2.90 per share for five (5) consecutive Trading Days (as defined in Section 20). -2- 4. Events of Default. An "Event of Default" shall have occurred hereunder if (a) any principal or interest payment due hereunder is not paid within five (5) calendar days of its due date, (b) the Maker becomes or is adjudged insolvent (meaning the inability to meet its obligations as and when due), (c) the Maker makes an assignment for the benefit of its creditors or files a petition in bankruptcy, (d) an involuntary petition in bankruptcy (or other similar statue) is filed against the Maker and is not dismissed within thirty (30) days after the filing thereof, or (e) the acceleration of any publicly traded indebtedness of the Maker. If any such Event of Default occurs, the holder hereof, at its option, may, among other things, declare all sums due hereunder immediately due and payable in cash and, thereafter, any amounts due hereunder and not paid shall bear interest at the lower of (i) the maximum rate permitted by applicable law or (ii) 18% per annum. 5. Application and Place of Payments. All payments, made on account of this Note shall be applied first to the payment of interest on unpaid interest, then to any accrued and unpaid interest hereunder, and the remainder, if any, shall be applied to the unpaid Principal Sum. All payments on account of this Note shall be paid to Payee, with notice of such payment to Payee, in lawful money of the United States of America in immediately available funds during regular business hours of Payee at Payee's principal offices or at such other times and places as Payee or Payee may at any time and from time to time designate in writing to Maker. 6. Setoff. Notwithstanding anything to the contrary herein, the Maker shall have the right, but not the obligation, to setoff against the following portion of the Purchase Price: (i) $1,000,000 held in escrow pursuant to the Escrow Agreement, (ii) $2,000,000 of the $4,000,000 due and payable on the second Payment Date hereunder; and (iii) $4,000,000 due and payable on the third Payment Date hereunder, in whole or in part, for any claims pursuant to Article 7 of the Asset Purchase Agreement that in Maker's good faith and reasonable estimate, could be expected to result in Damages to the Business in excess of $1,000,000. Any amounts setoff by Maker pursuant to this Section 6 that are subsequently delivered to Payee shall be paid in cash. Notwithstanding anything to the contrary set forth in this Note or any other agreement or instrument contemplated hereby, the Maker shall not be entitled to any setoff unless the Maker provides prior written notice of its intent to setoff to the Payee, which notice shall be effective when sent and state in reasonable detail the Maker's good faith basis for, and estimate of, the aggregate amount of its total claim for setoff. The Maker agrees to consult with the Payee for a period of not less than ten (10) days after the delivery of such notice by the Maker regarding the proposed setoff, provided, however, that the Maker shall have a right to withhold payment hereunder during any such period of consultation. The reasonable exercise of such right of setoff by the Maker in good faith, whether or not ultimately determined to be justified, will not constitute a breach or event of default under this Note. Neither the exercise of, nor the failure to exercise such right of setoff, will constitute an election of remedies or limit the Maker in any manner in the enforcement of any other remedies that may be available to it. 7. Assignment. ---------- (a) This Note shall be binding upon and shall inure to the benefit of Maker and Payee and their respective successors and permitted assigns. -3- (b) Payee may not assign, pledge or transfer this Note or the shares of Series A Preferred Stock into which this Note may be converted without the prior written consent of Maker. 8. No Waiver of Payee's Rights etc. No delay or failure on the part of Payee in exercising any of its options, powers or rights, nor any partial or single exercise of its options, powers or rights shall constitute a waiver thereof or of any other option, power or right, and no waiver on the part of Payee of any of its options, powers or rights shall constitute a waiver of any other option, power or right. Maker hereby waives presentment of payment, protest, and all notices or demands in connection with the delivery, acceptance, performance, default or endorsement of this Note. Acceptance by Payee of less than the full amount due and payable hereunder shall in no way limit the right of Payee to require full payment of all sums due and payable hereunder in accordance with the terms hereof. 9.

Dated:_______________________________ ------------------------------------ AETHER SYSTEMS, INC. ------------------------------------ Form of Notice of Conversion EXHIBIT G Certificate of Designation -------------------------- CERTIFICATE OF DESIGNATION OF SERIES A CONVERTIBLE REDEEMABLE PREFERRED STOCK OF AETHER SYSTEMS, INC. PURSUANT TO SECTION 151 OF THE DELAWARE GENERAL CORPORATION LAW Aether Systems, Inc., a corporation organized and existing under the laws of the State of Delaware (the "Corporation"), hereby certifies that pursuant to the authority contained in Article Fourth of the Corporation's Certificate of Incorporation, as amended, and in accordance with the provisions of Section 151 of the General Corporation Law of the State of Delaware (the "Code"), the Board of Directors of the Corporation has adopted, on February 25, 2002, the following resolution creating a series of preferred stock of the Corporation designated as the Series A Convertible Preferred Stock. WHEREAS, the Board of Directors of the Corporation is authorized by the Amended and Restated Certificate of Incorporation to issue up to 1,000,000 shares of preferred stock, par value $0.01 per share, in one or more classes or series and, in connection with the creation of any class or series, to fix by resolution providing for the issuance of shares the powers, designations, preferences and relative, participating, optional or other rights of the class or series and the qualifications, limitations or restrictions thereof; and WHEREAS, the Corporation has no shares of preferred stock that have been designated. NOW, THEREFORE, BE IT RESOLVED, by the Board of Directors of the Corporation, that pursuant to Article Fourth of the Certificate of Incorporation of the Corporation, there be, and hereby is, created a new series of preferred stock of the Corporation, par value $0.01 per share, and that the powers, designations, preferences and relative, participating, optional or other special rights and the qualifications, limitations and restrictions thereof shall be as follows: 1. Designation and Amount. The shares of such series shall be designated "Series A Convertible Redeemable Preferred Stock" (the "Series A Preferred Stock"). The number of shares initially constituting the Series A Preferred Stock shall be 3,000. 2. Dividends. No dividends shall be declared or paid on the Series A Preferred Stock. 3. Liquidation Preference. ---------------------- (a) Upon the occurrence of any liquidation, dissolution or winding up of the Corporation (or a deemed occurrence of such event pursuant to Section 3(c)), whether voluntary or involuntary, the holders of Series A Preferred Stock (the "Holders") then outstanding shall be entitled to receive out of the assets of the Corporation legally available for distribution, whether such assets are capital or surplus, prior and in preference to any distribution of any of the assets or funds of the Corporation to the holders of the common stock, par value $0.01 per share ("Common Stock") by reason of their ownership thereof, an amount equal to $5,000.00 per share of Series A Preferred Stock, appropriately adjusted for any recapitalizations, stock combinations, stock dividends, stock splits and the like (the "Original Issue Price" or "Liquidation Amount"). If upon the occurrence of a liquidation, dissolution or winding up (or deemed occurrence of such event pursuant to Section 3(c)), the assets and funds of the Corporation legally available for distribution to stockholders by reason of their ownership of the stock of the Corporation shall be insufficient to permit the payment to such holders of Series A Preferred Stock of the full Liquidation Amount for all the outstanding shares of Series A Preferred Stock then the entire assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series A Preferred Stock in proportion to the aggregate Liquidation Amount each holder is otherwise entitled to receive. (b) Upon the occurrence of any liquidation, dissolution or winding up of the Corporation (or a deemed occurrence of such event pursuant to Section 3(c)), whether voluntary or involuntary, after payment in full has been made to the holders of the Series A Preferred Stock of the full amounts to which they shall be entitled as provided in Section 3(a), the entire remaining assets and funds of the Corporation legally available for distribution to stockholders, if any, shall be distributed ratably among the holders of the Common Stock in proportion to the number of shares of Common Stock held by them. The Series A Preferred Stock shall have no right to participate in any distributions made pursuant to this Section 3(b). (c) A consolidation or merger of the Corporation with or into any other corporation or other entity, or a sale, lease, conveyance or other disposition (whether in one transaction or a series of related transactions) of all or substantially all of the assets of the Corporation, or the effectuation by the Corporation of any other transaction or series of related transactions, in each such case (other than the sale, lease or other disposition of all or substantially all of the assets) as a result of which the owners of the Corporation's outstanding voting securities immediately prior thereto do not own at least a majority of the outstanding voting securities of the surviving, resulting or consolidated entity (each such event(s) being a "Change of Control"), shall be deemed to be a liquidation, dissolution or winding up of the Corporation; provided, however, that the holder or holders of not less than a majority in voting power of the outstanding shares of Series A Preferred Stock may, at any time upon written notice to the Corporation, waive the provisions of this Section 3(c), and any such waiver shall be effective upon the holders of all outstanding shares of Series A Preferred Stock and Common Stock. (d) If any of the assets of the Corporation are to be distributed under this Section 3, or for any purpose, in a form other than cash, then the Board of Directors shall promptly and reasonably determine in good faith the fair market value of the assets to be distributed to the holders of Series A Preferred Stock or Common Stock. The Corporation shall, upon receipt of such determination, give prompt written notice of the determination to each holder of Series A Preferred Stock or Common Stock. 4. Conversion. ---------- (a) Conversions at Option of Holder. Each share of Series A Preferred Stock shall be convertible into shares of Common Stock (subject to the limitations set forth in Section 4(b) hereof), at the option of the Holder, at any time and from time to time from and after the earlier to occur of (x) the effectiveness of the Registration Statement on Form S-3 covering the 2 shares of Common Stock into which the Series A Preferred Stock is convertible (the "Registration Statement") and (y) the date that is one (1) year from the first issuance of a share of Series A Preferred Stock. Each share of Series A Preferred Stock shall be convertible into such number of shares of Common Stock as is determined by dividing the Original Issue Price by the Conversion Price (as defined below) at the time in effect for such conversion. The "Conversion Price" per share of Series A Preferred Stock shall be equal to the average daily closing bid prices of the Common Stock on the NASDAQ National Market (or if delisted from the NASDAQ National Market, the following markets in order of priority: the NASDAQ SmallCap Market, the over-the-counter bulletin board, and, finally, the pink sheets trading facility) for the three Trading Days (as defined below) before such conversion date and ending on the Trading Day prior to such conversion date. (b) Certain Conversion Restrictions. ------------------------------- (i) A Holder may not convert shares of Series A Preferred Stock or receive shares of Common Stock as payment of dividends hereunder to the extent such conversion or receipt of such dividend payment would result in the Holder, together with any affiliate thereof, beneficially owning (as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules promulgated thereunder) in excess of 4.999% of the then issued and outstanding shares of Common Stock, including shares issuable upon conversion of the shares of Series A Preferred Stock held by such Holder after application of this Section. Because the Holder will not be obligated to report to the Corporation the number of shares of Common Stock it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of 4.999% of the then outstanding shares of Common Stock without regard to any other shares which may be beneficially owned by the Holder or an affiliate thereof, the Holder shall have the authority and obligation to determine whether the restriction contained in this Section will limit any particular conversion hereunder, and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the shares of Series A Preferred Stock are convertible shall be the responsibility and obligation of the Holder. If the Holder has delivered a Conversion Notice (as defined below) for shares of Series A Preferred Stock that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in excess of the permitted amount hereunder, the Corporation shall notify the Holder of this fact and shall honor the conversion for the maximum number of shares of Series A Preferred Stock permitted to be converted on such date that shares are actually converted (such date referred to herein as the "Conversion Date") in accordance with the periods described in Section 4(c) and, at the option of the Holder, either retain shares of Series A Preferred Stock tendered for conversion in excess of the permitted amount hereunder for future conversions or return such excess shares of Series A Preferred Stock permitted to the Holder. The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than 61 days prior notice to the Corporation. Other Holders shall be unaffected by any such waiver. (ii) A Holder may not convert shares of Series A Preferred Stock or receive shares of Common Stock as payment of dividends hereunder to the extent such conversion or receipt of such dividend payment would result in the Holder, together with any affiliate thereof, beneficially owning (as determined in accordance with Section 13(d) of the 3 Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the then issued and outstanding shares of Common Stock, including shares issuable upon conversion of the shares of Series A Preferred Stock held by such Holder after application of this Section. Because the Holder will not be obligated to report to the Corporation the number of shares of Common Stock it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of 9.999% of the then outstanding shares of Common Stock without regard to any other shares which may be beneficially owned by the Holder or an affiliate thereof, the Holder shall have the authority and obligation to determine whether the restriction contained in this Section will limit any particular conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the shares of Series A Preferred Stock are convertible shall be the responsibility and obligation of the Holder. If the Holder has delivered a Conversion Notice for shares of Series A Preferred Stock that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in excess of the permitted amount hereunder, the Corporation shall notify the Holder of this fact and shall honor the conversion for the maximum number of shares of Series A Preferred Stock permitted to be converted on such Conversion Date in accordance with the periods described in Section 4(c) and, at the option of the Holder, either retain shares of Series A Preferred Stock tendered for conversion in excess of the permitted amount hereunder for future conversions or return such excess shares of Series A Preferred Stock permitted to the Holder. The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than 61 days prior notice to the Corporation. Other Holders shall be unaffected by any such waiver. (iii) The maximum number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock is 35,000 shares per day. (c) Mechanics of Conversion. Before any holder of Series A Preferred Stock shall be entitled to convert the same into shares of Common Stock, such holder shall deliver at the office of the Corporation and of any transfer agent for such Series A Preferred Stock (i) written notice of the election to convert the same and shall state therein the name or names in which the certificate or certificates for shares of Common Stock are to be issued and the number of shares of Series A Preferred Stock to be converted (the "Conversion Notice") to the Corporation; and (ii) either (A) surrender the certificate or certificates therefor, duly endorsed, or (B) if such Holder has notified the Corporation that such certificate has been lost, stolen or destroyed, deliver a duly endorsed lost stock affidavit reasonably satisfactory to the Corporation (including without limitation an indemnification obligation). The Corporation shall, within three Trading Days after receiving the Conversion Notice and surrendered certificate(s), issue and deliver at such office to such holder of Series A Preferred Stock, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid, and issue one or more certificates representing the number of shares of Series A Preferred Stock not converted, provided however, that the Corporation shall have the right but not the obligation to redeem all or any part of the Series A Preferred Stock pursuant to Section 6 hereof at any time prior to the issuance and delivery of the Common Stock. Any such shares of Series A Preferred Stock to be converted, that are not redeemed by the Corporation shall be deemed to have been converted immediately prior to the close of business on the date that is three (3) Trading Days after the surrender of the shares of Series A Preferred Stock to be converted, and the person or persons entitled to receive the shares 4 of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of such date. As used in this Certificate of Designation, a "Trading Day" shall mean (x) a day on which the Common Stock is then listed or quoted on the Nasdaq National Market or the Nasdaq SmallCap Market, as the case may be, or (y) if the Common Stock is not listed on either market, a day on which the Common stock is traded in the over-the-counter market, as reported by the OTC, or (z) if the Common Stock is not quoted on the OTC, a day on which the Common Stock is quoted in the over-the-counter "pink sheets" market; provided, however, that in the event that the Common Stock is not listed or quoted as set forth in (a), (b) and (c) hereof, then Trading Day shall mean any day other than a Saturday, Sunday or a federal holiday. (d) Reservation of Stock Issuable Upon Conversion. The Corporation covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock solely for the purpose of issuance upon conversion of Series A Preferred Stock, as herein provided, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holders, not less than such number of shares of Common Stock as shall be issuable (taking into account the provisions of Section 4(b) and Section 4(c) upon the conversion of all outstanding shares of Series A Preferred Stock. The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized, issued and fully paid and nonassessable. (e) No Fractional Shares. Upon a conversion hereunder the Corporation shall not be required to issue stock certificates representing fractions of shares of Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share to which a Holder would be entitled equal to such fraction multiplied by the Conversion Price. (f) Taxes. The issuance of certificates for Common Stock on conversion of Series A Preferred Stock shall be made without charge to the Holders thereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Corporation 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 Holder of such shares of Series A Preferred Stock so converted. (g) Reissuance. Shares of Series A Preferred Stock converted into Common Stock or redeemed in accordance with the terms hereof shall be canceled and may not be reissued. (h) Notices. Any notice required by the provisions of this Section 4 to be given to the holders of Series A Preferred Stock shall be deemed given if delivered pursuant to an agreement between the initial Holder and the Corporation. 5. Voting Rights. The holders of Series A Preferred Stock shall have no voting rights, except as set forth herein or as required by theCode. 6. Optional Redemption. ------------------- 5 (a) Subject to Section 6(b), at any time and from time to time, the Corporation shall have the right but not the obligation to redeem all or any part of the issued and outstanding shares of Series A Preferred Stock at a price per share equal to the Original Issue Price. With respect to such redemption, this Corporation shall give at least five (5) Trading Days' written notice (except with respect to a redemption pursuant to Section 4(c) hereof in which case such notice may be delivered anytime prior to redemption (including without limitation on the same day as the redemption)) to each holder of Series A Preferred Stock to be redeemed (the "Optional Redemption Notice"), which notice shall state the date of the redemption (the "Optional Redemption Date"), the number of shares to be redeemed, the aggregate Original Issue Price and the place where such holder may obtain payment of such Original Issue Price. On such Optional Redemption Date, each holder of Series A Preferred Stock called for redemption shall surrender to this Corporation or its transfer agent all certificates for the shares of Series A Preferred Stock to be redeemed; provided, however, that on such Optional Redemption Date (whether or not the certificates representing such shares are so surrendered), all rights of the respective holders of such shares with respect to the ownership thereof shall cease, except for the right to receive the Original Issue Price hereunder upon surrender of such certificates. (b) Failure by the Corporation to pay any portion of the aggregate Original Issue Price owed under this Section by the tenth (10th) Trading Day following the Optional Redemption Date shall, at the option of the Holder subject thereto, result in the invalidation ab initio of the unpaid portion of such optional redemption, and, notwithstanding anything herein to the contrary, the Corporation shall thereafter have no further rights to optionally redeem any shares of Series A Preferred Stock. In such event, the Corporation shall, at the option of the Holder not later than three (3) Trading Days from the receipt of Holder's request therefore, return to the Holder all of the shares of Series A Preferred Stock for which such aggregate Original Issue Price owed under this Section has not been paid in full. 7. Redemption Upon Triggering Events. ---------------------------------- (a) Upon the occurrence of a Triggering Event (as defined below), each Holder shall (in addition to all other rights it may have hereunder or under applicable law), have the right, exercisable at the sole option of such Holder, to require the Corporation to redeem all or a portion of the issued and outstanding shares of Series A Preferred Stock then held by such Holder for a redemption price, in cash, equal to the Original Issue Price. The Original Issue Price shall be due and payable within ten (10) Trading Days of the date on which the notice for the payment therefore is provided by a Holder. If the Corporation fails to pay the aggregate Original Issue Price owed under this Section in full pursuant to this Section 7 on the date such amount is due in accordance with this Section 7, the Corporation will pay interest thereon at a rate of 18% per annum (or the lesser amount permitted by applicable law), accruing daily from such date until the aggregate Original Issue Price owed under this Section, plus all such interest thereon, is paid in full. For purposes of this Section 7, a share of Series A Preferred Stock is outstanding from the date of its issuance until such date as the Holder shall have received either: (i) shares of Common Stock upon a conversion (or attempted conversion) thereof that meets the requirements hereof; or (ii) cash equal to the Original Issue Price upon a redemption. For the avoidance of doubt, the right of redemption under this Section 7 shall not apply to any shares of Series A Preferred Stock issued after the date on which a particular Triggering Event occurred 6 unless and until the occurrence of another Triggering Event (which may be the continuation of an uncured Triggering Event in Section 7(b)(i) or Section 7(b)(ii) hereof). (b) "Triggering Event" means any one or more of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body): (i) the Corporation shall fail to have available a sufficient number of authorized and unreserved shares of Common Stock to issue to such Holder upon a conversion hereunder; (ii) the Common Stock is no longer listed for trading on either the Nasdaq National Market or the Nasdaq SmallCap Market; (iii) the closing bid price of the Corporation's Common Stock is less $2.90 per share for five (5) consecutive Trading Days; or (iv) a registration statement covering the resale of the Common Stock shall not have become effective by July 5, 2002. 8. Protective Provisions. The Corporation shall not, without first obtaining the approval (by vote or written consent, as provided by law) of at least a majority of the then outstanding shares of Series A Preferred Stock, voting together as a single class, amend or change this certificate of designation or its certificate of incorporation in any manner that would adversely affect any of the rights, preferences, privileges or powers of, the Series A Preferred Stock.

The Company shall have twenty (20) days to file such additional Registration Statements.

(e) Use commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of the Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Shares for sale in any jurisdiction, at the earliest practicable moment. (f) Furnish to @Track and its counsel, without charge, at least two (2) conformed copies of each Registration Statement and each amendment thereto (including the Prospectus, but excluding all documents incorporated or deemed to be incorporated therein by reference, and all exhibits) promptly after the filing of such documents with the Commission. (g) Promptly deliver to @Track and its counsel, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as @Track and its counsel may reasonably request. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by @Track in connection with the offering and sale of the Registrable Shares covered by such Prospectus and any amendment or supplement thereto. (h) Upon the occurrence of any event contemplated by Section 2.2(d)(vi), as promptly as possible, prepare a supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. 6 (i) Prior to any public offering of Registrable Shares, use commercially reasonable efforts to register or qualify or cooperate with @Track and its counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Shares for offer and sale under the securities or blue sky laws of such jurisdictions within the United States as @Track shall reasonably request in writing, to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Shares covered by a Registration Statement; provided, that the Company shall not be required to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction where it is not then so qualified or subject the Company to any material tax in any such jurisdiction where it is not then so subject. (j) Comply with all applicable rules and regulations of the Commission.

(n) If the Company has delivered a Prospectus to @Track and after having done so determined that the Prospectus must be amended or supplemented in order to comply with the requirements of the Securities Act or this Agreement, the Company shall promptly notify @Track and, if requested, @Track shall immediately cease making offers of Registrable Shares and return all Prospectuses then in possession of @Track to the Company. The Company shall promptly provide @Track with amended or supplemented Prospectuses and, following receipt of the revised Prospectuses, @Track shall be free to resume making offers of the Registrable Shares. 7 (o) Notwithstanding anything in this Agreement to the contrary, @Track shall not have the right to object to any exhibit to any Registration Statement or Prospectus.

The Company hereby agrees to execute an acknowledgement of the Rule 10b5-1 plan by and between @Track and a nationally recognized investment bank selected by the Company that is reasonably acceptable to @Track and pay the fees as required above. 2.4 Indemnification and Contribution. -------------------------------- (a) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company shall thereafter indemnify and hold harmless @Track, each underwriter of such Registrable Shares, and each other person, if any, who controls @Track, its directors officers, employees, agents and affiliates, and any underwriter within the meaning of Section 15 of the Securities Act from and against any and all Damages to which @Track, its directors, officers, employees, agents and affiliates, or any underwriter or controlling person may become subject under the Securities Act, the Exchange Act, state securities or blue sky laws or otherwise, insofar as such Damages (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary Prospectus or final Prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arise out of or are based upon the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and the Company will reimburse @Track, its directors, officers, employees, agents and affiliates, any underwriter and each such controlling person for any legal or any other expenses reasonably incurred by @Track, its directors, officers, employees, agents and affiliates, or any underwriter or controlling person in connection with investigating or defending any such Damages as the same are incurred upon receiving reasonable written detail with respect thereto; provided, however, that the Company will not be liable under this Section 2.4 in any such case to the extent that any such Damages arise out of or are based upon any untrue statement or omission made in such Registration Statement, preliminary Prospectus or Prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in 8 writing, by or on behalf of @Track, underwriter or controlling person specifically for use in the preparation thereof. (b) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, @Track, shall thereafter indemnify and hold harmless the Company, each of its directors, officers, employees, agents and affiliates and each underwriter and each other person, if any, who controls the Company or any such underwriter within the meaning of Section 15 of the Securities Act, from and against any Damages to which the Company, its directors, officers, employees, agents and affiliates, or any underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities or blue sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based solely upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary Prospectus or final Prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and @Track will reimburse the Company, its directors, officers, employees, agents and affiliates, any underwriter and each such controlling person for any legal or any other expenses reasonably incurred by the Company, its directors, officers, employees, agents and affiliates, or any underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action as the same are incurred upon receiving reasonable written detail with respect thereto, if the statement or omission was made in reliance upon and in conformity with information relating to @Track furnished in writing to the Company by @Track or its counsel specifically for use in connection with the preparation of such Registration Statement, Prospectus, amendment or supplement (including without limitation all comments provided by @Track pursuant to Section 2.2). (c) Each party entitled to indemnification under this Section (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld); and, provided, further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section except to the extent that the Indemnifying Party is adversely affected by such failure. The Indemnified Party may participate in such defense at such party's expense; provided, however, that the Indemnifying Party shall pay such expense if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding; provided further that in no event shall the Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for the Indemnified Party. The Indemnifying Party also shall be responsible for the expenses of such defense if the Indemnifying Party does not elect to assume such defense. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any 9 judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of anyjudgment or settle such claim or litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 2.4 is due in accordance with its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any Damages, then the Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such Damages to which such party may be subject in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and @Track on the other in connection with the statements or omissions which resulted in such Damages, as well as any other relevant equitable considerations. The relative fault of the Company and @Track shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact related to information supplied by the Company or @Track and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and @Track agree that it would not be just and equitable if contribution pursuant to this Section 2.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph of Section 2.4, in no case shall @Track be liable or responsible for any amount in excess of the net proceeds received by @Track from the offering of Registrable Shares; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section, notify such party or parties from whom contribution may be sought, but the omission to notify such party or parties from whom contribution may be sought shall not relieve such party from any other obligation it or they may have thereunder or otherwise under this Section. (e) No party shall be liable for indemnification or contribution with respect to any action, suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably withheld.

(f) All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten (10) Business Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder). 10 2.5 Conditions. The Company's obligations to @Track under this Agreement will be conditioned on compliance with the following: (a) @Track will cooperate with the Company in connection with the preparation of the applicable Registration Statement, and for so long as the Company is obligated to keep such Registration Statement effective, @Track will provide to the Company, in writing and in a timely manner, for use in such Registration Statement (and expressly identified in writing as such), all relevant information regarding it and such other information as may be required by applicable law to enable the Company to prepare such Registration Statement and the related Prospectus covering the Registrable Shares owned by @Track and to maintain the accuracy, completeness and effectiveness thereof; (b) During such time as @Track may be engaged in a distribution of the Registrable Shares, @Track will comply with all applicable laws, including Regulation M promulgated under the Exchange Act, and, to the extent required by such laws, will, among other things: (A) not engage in any stabilization activity in connection with the securities of the Company in contravention of such rules; (B) distribute the Registrable Shares acquired by it solely in the manner described in the applicable Registration Statement; and (C) if required by applicable law, rules or regulations, cause to be furnished to each agent or broker-dealer to or through whom such Registrable Shares may be offered, or to the offeree if an offer is made directly by @Track, such copies of the applicable Prospectus (as amended and supplemented to such date) and documents incorporated by reference therein as may be required by such agent, broker-dealer or offeree; provided that the Company shall provide @Track with an adequate number of copies thereof for such purposes at the Company's expense; (c) @Track will permit the Company and its representatives and agents to examine relevant documents and records, and will supply in a timely manner any information as they may reasonably request, in connection with the offering or other distribution of Registrable Shares by @Track; and (d) On notice from the Company of the happening of an event specified in Section 2.2(d), or that requires the suspension by @Track of the distribution of any of the Registrable Shares owned by @Track, then @Track will immediately cease offering or distributing the Registrable Shares owned by it until the offering and distribution of the Registrable Shares owned by @Track may recommence in accordance with the terms hereof and applicable law. For the avoidance of doubt, not only do the Company's obligations hereunder to @Track not arise unless each of the preceding conditions are satisfied, the Company's timing obligations hereunder shall be tolled for the period during which such condition remained unfulfilled. 2.6 Suspension of Sales. ------------------- (a) Notwithstanding anything to the contrary in this Agreement, if at any time after the filing of a Registration Statement, and either (i) after the date upon which all shares of Series A Preferred Stock issued pursuant to the Note could have been converted into shares of Common Stock, assuming the conversion of 35,000 shares per Trading Day, plus ten 11 (10) Trading Days; provided, however, that any Trading Day in which: (A) the Registration Statement is not effective for any reason, or (B) there is the existence of a Triggering Event (as defined in the Certificate of Designation), such Trading Day shall not count toward the above time period and such period shall be extended by such number of Trading Days; or (ii) at any time the Company suspends the distribution of shares under all other then effective registration statements (including without limitation, those on Form S-3 and S-8), if any, a majority of the Board of Directors of the Company determines, in its good faith business judgment, that the offering or sale of Registrable Shares covered by such Registration Statement would materially interfere with or otherwise materially adversely affect any financing, acquisition, corporate reorganization or other material transaction or development involving the Company or require the Company to disclose matters that otherwise would not be required to be disclosed at such time and the disclosure of which would be materially adverse to the interests of the Company, then the Company may require the suspension of the distribution of any Registrable Shares under that Registration Statement (a "Blackout Period") by giving written notice to @Track; provided that the Company may not impose such Blackout Period unless its executive officers are under substantially similar restrictions. Any such notice need not specify the reasons for such suspension if a majority of the Board of Directors of the Company determines, in its good faith business judgment, that doing so would interfere with or adversely affect such transaction or development or would result in the disclosure of material non-public information. In the event that such notice is given, then until a majority of the Board of Directors of the Company has determined, in its good faith business judgment, that such distribution would no longer materially interfere with the matters described in the preceding sentence and has given written notice thereof to @Track, the Company's obligations under this Agreement to update or keep current such Registration Statement and @Track's right to sell Registrable Shares pursuant to such Registration Statement will be suspended, provided, that such suspension shall not exceed the first to occur of (x) the filing of the Company's next filing with the Commission and (y) ninety (90) days. (b) Notwithstanding anything to the contrary in this Agreement, and only after the date upon which all shares of Series A Preferred Stock issued pursuant to the Note could have been converted into shares of Common Stock, assuming the conversion of 35,000 shares per Trading Day, plus ten (10) Trading Days; provided, however, that any Trading Day in which: (A) the Registration Statement is not effective for any reason, or (B) there is the existence of a Triggering Event (as defined in the Certificate of Designation), such Trading Day shall not count toward the above time period and such period shall be extended by such number of Trading Days, if requested by the Company and the managing underwriter of an underwritten public offering by the Company of Common Stock, @Track shall not sell or otherwise transfer or dispose of any Registrable Shares or other securities of the Company held by @Track for a period of up to ninety (90) days following the effective date of a registration statement covering securities of the Company to be sold on its behalf to the public in an underwritten offering. The Company may impose stop-transfer instructions with respect to the Registrable Shares or other securities subject to the foregoing restriction until the end of such 90-day period. If @Track receives any written notice from the Company regarding the Company's plans to file a registration statement @Track shall treat such notice confidentially and shall not disclose such information to any person other than as necessary to exercise its rights under this Agreement. Notwithstanding the foregoing, the Company may not impose any such stop-transfer instructions unless its executive officers are under substantially similar restrictions. 12 (c) Notwithstanding Section (a) and Section (b) above, the Company shall only have the right to impose (i) a Blackout Period under Section (a) and (ii) a stop transfer order under Section (b) for up to an aggregate of 90 days in any 360 day period. 2.7 Rule 144 Requirements. The Company agrees to: --------------------- (a) make and keep current public information about the Company available, as those terms are understood and defined in Rule 144; (b) use commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time it is subject to such reporting requirements); and (c) furnish to @Track upon request (i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act (at any time it is subject to such reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents of the Company as @Track may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without registration. ` 2.8 Termination. All of the Company's obligations to keep the Registration Statement referenced in Sections 2.1 of this Agreement effective shall terminate at such time as there are no Registrable Shares. 2.9 Piggy-Back Registrations. If at any time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable Shares and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or the then equivalent respective form relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, and other than an underwritten offering, then the Company shall send to @Track written notice of such determination and, if within fifteen days after receipt of such notice, @Track shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Shares @Track requests to be registered. 3. General. ------- (a) Remedies. In the event of a breach by the Company or by @Track, of any of their obligations under this Agreement, @Track or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement.

[NOTARY PUBLIC SEAL] ============================ Tiffany R. Sweeden My Commission Expires /s/ TIFFANY R. SWEEDEN March 20, 2004 ------------------------------- ============================ Notary Public in and for the State of T E X A S EXHIBIT M Preferred Stock Conversion Agreement ------------------------------------ EXECUTION COPY AETHER SYSTEMS, INC. -------------------- PREFERRED STOCK CONVERSION AGREEMENT ------------------------------------ THIS PREFERRED STOCK CONVERSION AGREEMENT (this "Agreement") dated to be effective among the parties hereto as of March 15, 2002 is entered into by and among Aether Systems, Inc. a Delaware corporation (the "Corporation"), and @Track Communications, Inc., a Delaware Corporation ("Holder"). WHEREAS, the Corporation and Holder have entered into that certain Asset Purchase Agreement of even date herewith (the "Asset Purchase Agreement"), pursuant to which the Corporation has acquired certain assets from Holder in return for consideration consisting of $3,000,000 in cash and the Note, which is payable at the election of the Corporation in cash or in shares of Series A Preferred Stock, which shares are, in turn, convertible into shares of Common Stock; and WHEREAS, the Corporation and Holder desire to provide for certain arrangements with respect to the conversion of shares of the Series A Preferred Stock issued by the Corporation pursuant to the Note into shares of the Corporation's Common Stock; and NOW, THEREFORE, in consideration of the mutual promises and covenants contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 1. Capitalized terms used herein but not defined shall have the meanings ascribed to them in the Certificate of Designation of Series A Convertible Redeemable Preferred Stock of the Corporation (the "Certificate"). 2. Conversions at Option of Holder. Each share of Series A Preferred Stock shall be convertible into shares of Common Stock at the option of the Holder, subject to the limitations set forth in the Certificate. 3. Mechanics of Conversion. Holder shall effect conversions in the manner provided in Section 4(c) of the Certificate and subject to the conversion restrictions set forth in Section 4(b) of the Certificate. Holder shall use the notice of conversion attached hereto as Exhibit A ("Conversion Notice") to effect any conversion of Series A Preferred Stock into Common Stock. The Corporation shall, upon the reasonable request of the Holder, if available, use commercially reasonable efforts to deliver any certificate or certificates required to be delivered by the Corporation electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions. 4. Damages. If upon a properly exercised conversion by the Holder pursuant to this Agreement and the Certificate, the Corporation fails to deliver to the Holder such certificate or certificates required to be delivered pursuant to Section 4(c) of the Certificate, by the third Trading Day after the date that a Conversion Notice is properly delivered to the Corporation and if after such third Trading Day the Holder purchases (in an open market transaction) Common Stock to deliver in satisfaction of a sale by such Holder of the shares of Common Stock which the Holder was entitled to receive upon such conversion (a "Buy-In"), then the Corporation shall (A) pay in cash as liquidated damages and not as a penalty, to the Holder the amount by which (x) the Holder's total purchase price (including reasonable brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive, but did not receive, from the conversion at issue multiplied by (2) the market price of the Common Stock at the time of the sale giving rise to such purchase obligation, provided, however, that the Corporation shall not be liable for such Buy-In damages if the failure to deliver the shares of Common Stock as required was through no fault of the Corporation. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series A Preferred Stock with respect to which the market price of the shares of Common Stock on the date of conversion totaled $10,000, under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay the Holder $1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to the Holder in respect of the Buy-In. Holder's right to receive payment under this Section 3 shall be its sole remedy for any failure by the Corporation to deliver the shares of Common Stock as required under the Certificate. 5. Notices. Any and all notices or other communications required by the provisions of the Certificate and/or this Agreement to be given by the Holder, including any Conversion Notice, shall be in writing and delivered by confirmed facsimile with a concurrent confirmed email as set forth below; facsimile number: 443 ###-###-####, Attention: Chauncey Martin; and email address: ***@***; provided, however, that the Holder shall not be responsible for failing to provide notice due to the failure of the Corporation's communications devices and/or infrastructure. With a copy, which shall not constitute notice hereunder, to; (i) the Corporation's transfer agent at BankBoston, N.A., Transfer Agent and Registrar, Mail Stop: 45-02-62, 150 Royall Street, Canton, MA 02021 Attn: Paula Gill, facsimile number ###-###-####, and (ii) Wilmer, Cutler & Pickering, 2445 M Street, NW, Washington DC 20037, Attn: Mark A. Dewire, Esq., facsimile number ###-###-####. For the avoidance of doubt, notice given by either facsimile or email alone shall not be sufficient notice hereunder. Such notice shall be deemed effective (i) on the Trading Day received, if received by 1:00 P.M. Baltimore, Maryland time, or (ii) on the next Trading Day, if received (A) on any day that is not a Trading Day or (B) after 1:00 P.M Baltimore, Maryland time on a Trading Day. Any and all notices or other communications or deliveries to be provided by the Corporation pursuant to the terms of the Certificate or hereunder shall be in writing and delivered personally, or sent by a nationally recognized overnight courier service, addressed to the Holder at the address of the Holder appearing on the books of the Corporation, or if no such address appears, at the principal place of business of the Holder. Any notice or other communication or delivery required to be given pursuant to the Certificate or hereunder shall be deemed given when delivered if personally delivered, or the next Business Day if sent via overnight courier. Either the Holder or the Corporation may change its notice address, facsimile number or email address (if applicable) by delivering notice to the other party as provided in this Section. 6. Cooperation. Upon conversion, the Corporation shall cooperate with Holder to facilitate the timely preparation and delivery of certificates representing the shares of Common Stock to be delivered to a transferee pursuant to a Registration Statement (as defined in the Asset Purchase Agreement), which certificates shall be free, to the extent permitted by the Asset 2 Purchase Agreement and Certificate, of all restrictive legends, and to enable such shares of Common Stock to be in such denominations and registered in such names as Holder may designate. 7. Force Majeure. Neither party may be deemed in default hereunder, nor shall it hold the other party responsible for any cessation, interruption or delay in the performance of its obligations under this Agreement due to causes beyond its reasonable control, including: any fire, flood, earthquake or other natural disaster, act of God, war or armed conflict (whether or not officially declared), strikes, civil disturbance, disruption of the public markets or the failure of supply, transportation, telecommunications, power or other essential commodity or service required in the conduct of its business, and other similar causes to those listed, in each case where failure to perform is beyond the reasonable control, and not caused by the negligence of, the non-performing party. The Corporation's timing obligations under this Agreement shall be tolled for the same period of time caused by a force majeure event. 8. Termination. This Agreement shall terminate and be of no further force or effect at such time as there are no shares of Series A Preferred Stock held or owned by Holder. 9. Setoff. Notwithstanding anything to the contrary herein, the Corporation shall have the right, but not the obligation, to setoff against the following portion of the Purchase Price (as such term is defined in the Asset Purchase Agreement): (i) $1,000,000 held in escrow pursuant to the Escrow Agreement (as such term is defined in the Asset Purchase Agreement), (ii) $2,000,000 of the $4,000,000 due and payable sixty (60) days after Closing (as such term is defined in the Asset Purchase Agreement) pursuant to the Note; and (iii) $4,000,000 due and payable 90 days after Closing pursuant to the Note, in whole or in part, for any claims pursuant to Article 7 of the Asset Purchase Agreement that in the Corporation's good faith and reasonable estimate, could be expected to result in Damages to the Business (as such term is defined in the Asset Purchase Agreement) in excess of $1,000,000. Any amounts setoff by the Corporation pursuant to this Section 9 that are subsequently delivered to Holder shall be paid in cash. Notwithstanding anything to the contrary set forth in this Agreement or any other agreement or instrument contemplated hereby, the Corporation shall not be entitled to any setoff unless the Corporation provides prior written notice of its intent to setoff to the Holder, which notice shall be effective when sent and state in reasonable detail the Corporation's good faith basis for, and estimate of, the aggregate amount of its total claim for setoff. The Corporation agrees to consult with the Holder for a period of not less than ten (10) days after the delivery of such notice by the Corporation regarding the proposed setoff, provided, however, that the Corporation shall have a right to withhold payment hereunder during any such period of consultation. The reasonable exercise of such right of setoff by the Corporation in good faith, whether or not ultimately determined to be justified, will not constitute a breach or event of default under this Agreement. Neither the exercise of, nor the failure to exercise such right of setoff, will constitute an election of remedies or limit the Corporation in any manner in the enforcement of any other remedies that may be available to it. 10. General. ------- (a) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or 3 unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. (b) Governing Law. This Agreement shall be governed by and construed, interpreted and enforced in accordance with the laws of the State of Delaware without giving effect to the choice of law provisions thereof.
