               Section 5.   Covenants.

VitalStream shall at all times reserve and keep available out of its authorized but unissued shares of Conversion Preferred, solely for the purpose of issuance upon the conversion of the Amended and Restated Notes, such number of shares of Conversion Preferred issuable upon the conversion of all outstanding Amended and Restated Notes. All shares of Underlying Common Stock or Conversion Preferred, as the case may be, which are so issuable shall, when issued, be duly and validly issued, fully paid and non assessable and free from all Taxes and Liens. VitalStream shall take all such actions as may be necessary to assure that all such shares of Underlying Common Stock or Conversion Preferred, as the case may be, may be so issued without violation of any applicable Law or Legal Requirement or any requirements of any domestic securities exchange upon which shares of Underlying Common Stock or Conversion Preferred, as the case may be, may be listed (except for official notice of issuance which shall be immediately transmitted by VitalStream upon issuance).

               5B.   Intellectual Property Rights.  VitalStream shall possess and maintain all Intellectual Property Rights necessary to the conduct of its business and own all right, title and interest in and to, or have a valid and enforceable license to use, all such Intellectual Property Rights, except where VitalStream's failure to so possess, maintain, own or have a license to use such Intellectual Rights would not have a VitalStream Material Adverse Effect. VitalStream shall not take any action or fail to take any action which would result in the invalidity, abandonment, misuse or unenforceability of such Intellectual Property Rights or which would infringe upon or misappropriate any Intellectual Property Rights of other Persons, except where VitalStream's failure to take such action or failure to take such action, or such infringement or misappropriation, would not have a VitalStream Material Adverse Effect. For purposes of clarification, the parties agree that the grant of a Lien with respect to Intellectual Property rights otherwise permitted by the Transaction Agreements does not constitute any action which would result in the invalidity, abandonment, misuse or unenforceability of such Intellectual Property Rights. The covenants set forth in this Section 5B shall expire simultaneously with the expiration or termination of the covenants set forth in Section 8 of the Amended and Restated Notes.

               5C.   Compliance with Agreements.  VitalStream shall perform and observe all of its obligations to each holder of Amended and Restated Notes, Preferred Shares, Warrants and Underlying Common Stock as set forth in this Agreement and each of the other Transaction Agreements.

               5D.   Current Public Information.  VitalStream shall file all reports required to be filed by it under the Securities Act and the Securities Exchange Act and the rules and regulations adopted by the Securities and Exchange Commission thereunder, and will take such further action as any holder or holders of Restricted Securities may reasonably request, all to the extent required to enable such holders to sell Restricted Securities pursuant to (i) Rule 144 adopted by the Securities and Exchange Commission under the Securities Act (as such rule may be amended from time to time) or any similar rule or regulation hereafter adopted by the Securities and Exchange Commission or (ii) a registration statement on Form S-2 or S-3 or any similar registration form hereafter adopted by the Securities and Exchange Commission; provided, however, that the foregoing provision shall not be interpreted to require the VitalStream to file a registration statement on Form S-2 or S-3 other than as may be required pursuant to the Registration Agreement. Upon the request of the holders of a majority of the Underlying Common Stock, VitalStream will deliver to such holders a written statement as to whether it has complied with such requirements. The covenants set forth in this Section 5D shall expire on the date the Equity Securities and Debt Securities constituting the Restricted Securities immediately following the Closing cease to be Restricted Securities.

               5E.   Information Rights.  VitalStream shall deliver to Dolphin, upon request, so long as the Underlying Common Stock held by Dolphin or an Affiliated of Dolphin constitutes at least three percent of VitalStream's outstanding Common Stock, each monthly, quarterly and annual internally prepared financial statement and budget reporting packages delivered to the Board of Directors; provided, however, in connection with the receipt of any materials and other information by Dolphin pursuant to this Section 5E, Dolphin shall sign a confidentiality agreement in form and substance reasonably satisfactory to Dolphin and VitalStream to the extent required by Regulation FD promulgated under the Securities Act or any other securities law or regulation that would, absent such confidentiality agreement, require public disclosure of the information learned by Dolphin at such meeting or through the receipt of such information or materials.

               5F.   Public Disclosures.  VitalStream shall not disclose any Purchaser's name or identity as a stockholder of VitalStream in any press release or other public announcement or in any document or material filed with any Governmental Entity, without the prior written consent of such Purchaser, unless (i) such disclosure is required by applicable Law, in which case VitalStream shall use its best efforts to permit Purchaser to review and comment upon the form and substance of such disclosure, or (ii) such disclosure has previously been reported in any document or material filed with any Governmental Entity by either VitalStream or such Purchaser.

               5G.   Attorneys Fees.  Within thirty (30) days of the Closing, Dolphin shall deliver to VitalStream a detailed billing invoice for fees and expenses of legal counsel that were not paid by VitalStream at or before the Closing and that were incurred by Dolphin in connection with the preparation and review of this Agreement and the other Transaction Agreements (including the preparation and review of any agreement prepared following June 1, 2003 in contemplation of any proposed transactions with VitalStream or any VitalStream Subsidiary involving an additional investment in VitalStream or related to the amendment or restatement of the Original Notes) and the consummation of the Closing. Within ten (10) days of the receipt of such detailed billing invoice, VitalStream shall reimburse Dolphin for all fees and expenses of legal counsel that are reflected on such detailed billing invoice, up to a maximum aggregate amount of Fifty Thousand Dollars ($50,000) when combined with all fees and expenses paid by VitalStream at or before the Closing, and that were incurred in connection with the preparation and review of this Agreement and the other Transaction Agreements (including the preparation and review of any agreement prepared following June 1, 2003 in contemplation of any proposed transactions with VitalStream or any VitalStream Subsidiary involving an additional investment in VitalStream or related to the amendment or restatement of the Original Notes) and the consummation of the Closing.

               5H.   Filing of Certificate of Designation.

               If it has not done so before the date this Agreement is executed by all parties thereto, as soon as possible following the execution and delivery of this Agreement by all parties thereto, VitalStream shall deliver a fully executed Certificate of Designation to the Secretary of State of the State of Nevada and take such commercially reasonable steps as are necessary to cause the Certificate of Designation to be filed by the Secretary of State of the State of Nevada.

               Section 6.   Nature of Restricted Securities; Transfer of Restricted Securities; General Transfer Procedure.

               6A.   General Provisions.

               (i)   Each Purchaser acknowledges and agrees that the Amended and Restated Notes, Preferred Shares and Warrants it is purchasing and the Underlying Common Stock are characterized as "restricted securities" under the federal securities Laws inasmuch as they are being acquired from VitalStream in a transaction not involving a public offering and that under such Laws such securities may be resold without registration under the Securities Act only in certain limited circumstances as set forth in this Section 6. In the absence of an effective registration statement covering such securities or an available exemption from registration under the Securities Act, the Amended and Restated Notes, Preferred Shares, Warrants and Underlying Common Stock must be held indefinitely. In this connection, such Purchaser represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act, including without limitation the Rule 144 condition that current information about VitalStream be available to the public.

               (ii)   Restricted Securities are transferable only pursuant to (a) public offerings registered under the Securities Act, (b) Rule 144 or Rule 144A adopted by the Securities and Exchange Commission under the Securities Act (as such rules may be amended from time to time) or any similar rule or regulation hereafter adopted by the Securities and Exchange Commission if the exemption from registration under such rule is available and (c) subject to the conditions specified in Section 6B below, any other legally available means of transfer.

               (iii)   In addition to the restrictions set forth above, each Purchaser acknowledges and agrees that (to the extent such Purchaser is party to the Investor Rights Agreement) the Amended and Restated Notes, Preferred Shares, Warrants and the Underlying Common Stock and the transfer of any such Equity Securities is subject to the terms of the Investor Rights Agreement and the terms and provisions thereof.

               6B.   Opinion Delivery.  In connection with the transfer of any Restricted Securities (other than a transfer described in Section 6A(i) or Section 6A(ii) above), the holder thereof shall deliver written notice to VitalStream describing in reasonable detail the transfer or proposed transfer, together with an opinion of legal counsel which is knowledgeable in securities Law matters to the effect that such transfer of Restricted Securities may be effected without registration of such Restricted Securities under the Securities Act. In addition, if the transferring holder delivers to VitalStream an opinion of such legal counsel that no subsequent transfer of such Restricted Securities shall require registration under the Securities Act, VitalStream shall promptly upon such contemplated transfer deliver new certificates for such Restricted Securities which do not bear the Securities Act legend set forth in Section 8B(ii) of this Agreement. If VitalStream is not required to deliver new certificates for such Restricted Securities not bearing such legend, the holder thereof shall not transfer the same until the prospective transferee has confirmed to VitalStream in writing its agreement to be bound by the Investor Rights Agreement and the conditions contained in this Section 6 and Section 8B(ii) of this Agreement.

               6C.   Rule 144A.  Notwithstanding any provision of this Agreement to the contrary, upon the request of the holders of a majority of the Underlying Common Stock, VitalStream shall promptly supply to such holders or their prospective transferees all information regarding VitalStream required to be delivered in connection with a transfer pursuant to Rule 144A adopted by the Securities and Exchange Commission under the Securities Act (as such rule may be amended from time to time) or any similar rule or regulation hereafter adopted by the Securities and Exchange Commission.

               6D.   Legend Removal.  If any Restricted Securities become eligible for sale pursuant to Rule 144(k) adopted by the Securities and Exchange Commission under the Securities Act (as such rule may be amended from time to time) or any similar rule or regulation hereafter adopted by the Securities and Exchange Commission or an effective registration statement under the Securities Act, VitalStream shall, upon the request of the holder of such Restricted Securities, remove the legend set forth in Section 8B(ii) of this Agreement from the certificates for such Restricted Securities.

               Section 7.   Representations and Warranties of VitalStream and the VitalStream Subsidiaries.  As a material inducement to the Purchasers to enter into this Agreement, exchange the Original Notes and Original Warrants, and purchase the Preferred Units thereunder, VitalStream hereby represents and warrants to each of the Purchasers that the statements contained in this Section 7 are correct and complete as of the Closing Date (or on the date as of which they are made, in the case of any representation or warranty which specifically relates to an earlier date). For purposes of this Section 7, any matter disclosed on a Schedule in respect of a particular representation will be deemed to have been disclosed on a different Schedule in respect of a representation calling for a reasonably similar or related type of disclosure (even if such matter may have been omitted from such different Schedule), if and only to the extent that, it is reasonably clear from a reading of the disclosure on any such Schedule that it applies to such other Schedule.

               7A.   Approval and Consents; Authorization; No Breach.  VitalStream has full power and authority (including full corporate power and authority) to execute and deliver this Agreement and each of the other Transaction Agreements to which it is a party and to perform its obligations hereunder and thereunder. Without limiting the generality of the foregoing, the execution, delivery and performance by VitalStream of this Agreement and each of the other Transaction Agreements to which VitalStream is a party, have been duly authorized by VitalStream.

Except as set forth on Schedule 7(a) attached hereto, the execution and delivery by VitalStream of this Agreement and the other Transaction Agreements to which VitalStream or any VitalStream Subsidiary is a party, and the fulfillment of and compliance with the respective terms hereof and thereof by VitalStream or any VitalStream Subsidiary do not and shall not (i) conflict with or result in a breach of the terms, conditions or provisions of, (ii) constitute a default under or result in the violation of, (iii) result in the creation of any Lien upon the capital stock or assets of VitalStream or any VitalStream Subsidiary pursuant to, (iv) give any third party the right to modify, terminate or accelerate any obligation under, or (v) require any authorization, consent, approval, exemption or other action by or notice or declaration to, or filing with, any third party or any Governmental Entity pursuant to, (A) the charter documents or bylaws of VitalStream or any VitalStream Subsidiary, (B) to the Knowledge of VitalStream, any Law or Legal Requirement to which VitalStream or any VitalStream Subsidiary is subject, or (C) to the Knowledge of VitalStream any material agreement, instrument, order, judgment or decree to which VitalStream or any VitalStream Subsidiary is subject.

               7B.   Capital Stock and Related Matters.

               (i)   Immediately prior to the Closing, the authorized capital stock of VitalStream shall consist of (a) 290,000,000 shares of Common Stock, 31,158,392 of which shares of Common Stock shall be issued and outstanding and (b) 10,000,000 shares of Preferred Stock, none of which were issued and outstanding immediately prior to the Closing.

Except as set forth under the title "Newly Issued Shares" on Schedule 7(b), VitalStream has not issued any Equity Securities since January 15, 2003.

               (ii)   Except as set forth in Schedule 7(b) attached hereto or as contemplated by the transactions set forth in this Agreement, (i) as of the date of the stockholder list attached as part of Schedule 7(b) attached hereto, no person owns of record, or to VitalStream's Knowledge is known to own of record, any Equity Securities of VitalStream or any VitalStream Subsidiary; (ii) no subscription, warrant, option, convertible security, or other right (contingent or other) to purchase or otherwise acquire Equity Securities of VitalStream or any VitalStream Subsidiary authorized, granted or issued by VitalStream or any VitalStream Subsidiary or, to VitalStream's Knowledge, any other Person, is authorized or outstanding; (iii) there is no commitment of VitalStream or any VitalStream Subsidiary to issue shares, subscriptions, warrants, options, convertible securities, or other such rights (contingent or otherwise) or to distribute to holders of any of its Equity Securities or Debt Securities any evidence of indebtedness or assets. Except as provided for in the Articles of Incorporation, or as set forth in Schedule 7(b) attached hereto or as contemplated by the transactions set forth in this Agreement, neither VitalStream nor any VitalStream Subsidiary has any obligation (contingent or otherwise) to purchase, redeem, or otherwise acquire any of its Equity Securities or Debt Securities or any interest therein or to pay any dividend or make any other distribution in respect thereof. Immediately prior to the Closing, other than the Prior Investor Rights Agreement (as defined in the Investor Rights Agreement) and the AKKAD Agreement or as contemplated by the transactions set forth in this Agreement, there are no voting trusts or agreements, shareholders' agreements, pledge agreements, buy-sell agreements, rights of first refusal, preemptive rights or proxies relating to any Debt Securities or Equity Securities of VitalStream or any VitalStream Subsidiary to which VitalStream or any VitalStream Subsidiary is a party (or, to the Knowledge of VitalStream, by and between any other Person). All of the outstanding Debt Securities and Equity Securities of VitalStream and each VitalStream Subsidiary were issued in compliance with all applicable federal and state securities Laws.

               (iii)   Other than as set forth in the Prior Investor Rights Agreement, there are no statutory or contractual stockholders preemptive rights or rights of refusal with respect to the issuance of the Amended and Restated Notes, Additional Warrants, Amended and Restated Warrants, the Preferred Shares or Underlying Common Stock.
