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

6A. General Provisions.

(i) Each Purchaser acknowledges and agrees that the Convertible Notes 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 Convertible Notes, 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 the Convertible Notes may only be transferred in increments of a minimum of $100,000 and $1,000 increments in excess 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 9C(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 9C(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 9C(ii) of this Agreement from the certificates for such Restricted Securities.

(ii) The representations and warranties set forth in this Agreement shall survive each Closing (a) with respect to the matters covered by the representations and warranties contained in Section 7A, and Section 7B of this Agreement and Section 4(m), Section 4(o) and Section 4(r) of the Asset Purchase Agreement, until sixty (60) days after the expiration of all applicable statute of limitations (including all periods of extension, whether automatic or permissive) and (b) in the case of all other representations and warranties and any covenant or agreement contained in this Agreement to be performed on or prior to a Closing Date, until the date which is nine (9) months after such Closing Date.

(iii) In consideration of each Purchaser's execution and delivery of this Agreement and acquiring the Convertible Notes and Warrants hereunder and in addition to all of VitalStream's and the Buyer's other obligations under this Agreement and the other Transaction Agreements, VitalStream agrees to indemnify on an after-tax basis and defend, protect and hold harmless each Purchaser and its Affiliates and each of their respective directors, officers, employees, stockholders, members, partners, agents (including, without limitation, those retained in connection with the transactions contemplated by this

Agreement), successors and assigns (collectively, the "Indemnitees") from and against any and all Claims, costs, damages, deficiencies, expenses (including interest, court costs, fees of attorneys, accountants and other experts or other expenses of litigation or other proceedings or of any Claim, default or assessment), fees, fines, Liabilities, losses and penalties (hereinafter individually, a "Loss" and collectively, "Losses") which, directly or indirectly, arise out of, result from or relate to (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought): (a) any facts or circumstances which constitute a misrepresentation or breach by VitalStream or any VitalStream Subsidiary of any representation, warranty or covenant set forth in this Agreement (including any annex, exhibit or schedule attached hereto), any other Transaction Agreement or in any instrument or document delivered by VitalStream or the Buyer pursuant to this Agreement or (b) any non-fulfillment or breach of any covenant or agreement of VitalStream or any VitalStream Subsidiary set forth in this Agreement or any other Transaction Agreement. To the extent that the foregoing undertakings by VitalStream or the Buyer may be unenforceable for any reason, VitalStream and the Buyer shall make the maximum contribution to the payment and satisfaction of the Losses described above incurred by any Indemnitee which is permissible under applicable Law.

(b) Disclosure of Information. Each Purchaser hereby represents that it has received and reviewed the information about VitalStream and the VitalStream Subsidiaries that it has requested and represents that it has had an opportunity to ask questions and receive answers from VitalStream and the Buyer regarding the terms and conditions of the offering of the Convertible Notes and Warrants and the business, properties, prospects and financial condition of VitalStream and the VitalStream Subsidiaries that it has requested.

9D. Entire Agreement. This Agreement, the other Transaction Agreements and the other agreements and instruments referred to herein and therein contain the entire agreement between the parties hereto and supersede any prior understandings, agreements or representations by or between the parties hereto, written or oral, which may have related to the subject matter hereof in any way (including the Original Note Purchase Agreement).

9E. Successors and Assigns. Except as otherwise expressly provided herein or therein, all covenants and agreements contained in this Agreement or any other Transaction Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and assigns of the parties hereto whether so expressed or not. In addition, and whether or not any express assignment has been made, the provisions of this Agreement or any other Transaction Agreement which are for any Purchaser's benefit as a purchaser or holder of Convertible Notes, Warrants or Underlying Common Stock are also for the benefit of, and enforceable by, any subsequent holder of such Convertible Notes, Warrants or Underlying Common Stock.

9F. Counterparts. This Agreement or any other Transaction Agreement may be executed simultaneously in two or more counterparts, any one of which need not contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same agreement.

9G. Descriptive Headings; Interpretation. Section headings used in this Agreement or in any other Transaction Agreement are for convenience only and are not to affect the construction of, or to be taken into consideration in interpreting, such agreement. The use of the word "including" or any variation or derivative thereof in this Agreement or in any other Transaction Agreement is by way of example rather than by limitation.

9I. Consent to Amendments and Waivers. Except as otherwise provided herein, no modification, amendment or waiver of any provision of this Agreement shall be effective against VitalStream or the holders of the Convertible Notes, Warrants or Underlying Common Stock unless such modification, amendment or waiver is approved in writing by (i) VitalStream, in the case of any amendment, modification or waiver affecting the rights and interests VitalStream, (ii) in the case of any amendment, modification or waiver affecting the rights and interests of the holders of the Initial Convertible Notes, Warrants or Underlying Common Stock under this Agreement, the holders of a majority of the Underlying Common Stock with respect to such Initial Convertible Notes, Warrants or Underlying Common Stock and (iii) in the case of any amendment, modification or waiver affecting the rights and interests of any holder of Subsequent Convertible Notes or any Person listed on Annex 1 as obligated to purchase Subsequent Convertible Notes, the holders of a majority of the Underlying Common Stock with respect to such Subsequent Convertible Notes. Notwithstanding the foregoing, without the consent of any other Person, VitalStream may restate Annex 1 attached hereto to (a) add additional Persons who purchase Convertible Notes hereunder and execute and deliver a counterpart signature page to this Agreement or (b) change the addresses for notice to any Person at such Person's request. No other course of dealing between VitalStream and the holder of any Convertible Notes, Warrants or Underlying Common Stock or any delay in exercising any rights under this Agreement or any of the other Transaction Agreements shall operate as a waiver of any rights of any such holder. For purposes of this Agreement, Convertible Notes, Warrants or Underlying Common Stock held by VitalStream or any of the VitalStream Subsidiaries shall not be deemed to be outstanding. This Agreement shall amend and restate the Original Note Purchase Agreement in its entirety and become effective immediately upon the execution of this Agreement by each of the Parties hereto. The parties hereto hereby acknowledge and agree that (A) references to the "Convertible Promissory Note and Warrant Purchase Agreement", "Note Purchase Agreement" or "Note and Warrant Purchase Agreement, as the case may be, in each of the Transaction Agreements shall be to this Agreement (as amended and modified from time to time) and (B) references to the "Asset Purchase Agreement" in each of the Transaction Agreements shall be to the Asset Purchase Agreement (as defined herein) (as amended and modified from time to time).

9J. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision of this Agreement or any other Transaction Agreement is held to be prohibited by or invalid under applicable Law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement or such other Agreement.

9K. No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement and the other Transaction Agreements. In the event an ambiguity or question of intent or interpretation arises, this Agreement and the other Transaction Agreements shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement or any other Transaction Agreement. Any reference to any federal, state, local, or foreign Law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. Nothing in the schedules attached hereto (or, as applicable, to the Asset Purchase Agreement) shall be deemed adequate to disclose

an exception to a representation or warranty made herein unless the schedule attached hereto identifies the exception with particularity and describes the relevant facts in detail. Without limiting the generality of the foregoing, the mere listing (or inclusion of a copy) of a document or other item shall not be deemed adequate to disclose an exception to a representation or warranty made herein (unless the representation or warranty has to do with the existence of the document or other item itself). The parties hereto intend that each representation, warranty, and covenant contained herein shall have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty, or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party has not breached shall not detract from or mitigate the fact that such party is in breach of the first representation, warranty, or covenant.

9L. Incorporation of Annexes, Schedules and Exhibits. The annexes, schedules and exhibits identified in this Agreement are incorporated herein by reference and made a part hereof.

9M. Registered Holders; Ownership. As used in this Agreement and each of the other Transaction Agreements, references to a "holder" of Convertible Notes, Warrants or Underlying Common Stock shall mean the registered holder of such Convertible Notes, Warrants or Underlying Common Stock as set forth in VitalStream's records. For purposes of this Agreement and each of the other Transaction Agreements, all holdings of Convertible Note, Warrants and Underlying Common Stock by Persons who are Affiliates of each other shall be aggregated for purposes of meeting any threshold tests under this Agreement and each of the other Transaction Agreements.

9N. Consideration for Warrants and Notes. The Purchasers and VitalStream acknowledge and agree that (i) the fair market value of all of the Warrants (the "Aggregate Warrant Value") issued hereunder shall be an amount equal to the product of is (a) $0.055 multiplied by (b) the aggregate Warrant Share Amount (as defined in the Warrant) and (ii) the fair market value of all of the Convertible Notes issued hereunder is $1,100,000 minus the Aggregate Warrant Value. Each Purchaser and VitalStream shall file their respective federal, state and local Tax returns in a manner which is consistent with such valuation and allocation and shall not take any contrary position with any Taxing authority.

9O. Understanding Among the Purchasers. The determination of each Purchaser to purchase the Convertible Notes and Warrants pursuant to this Agreement has been made by such Purchaser independent of any other Purchaser and independent of any statements or opinions as to the advisability of such purchase or as to the properties, business, prospects or condition (financial or otherwise) of VitalStream and the VitalStream Subsidiaries which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser.

9P. GOVERNING LAW. TO THE EXTENT APPLICABLE, THE CORPORATE LAW OF THE STATE OF NEVADA SHALL GOVERN ALL ISSUES AND QUESTIONS CONCERNING THE RELATIVE RIGHTS AND OBLIGATIONS OF VITALSTREAM AND ITS SECURITYHOLDERS. ALL OTHER ISSUES AND QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT AND ANY OF THE OTHER TRANSACTION AGREEMENTS AND THE ANNEXES, EXHIBITS AND SCHEDULES HERETO AND THERETO SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW RULES OR PROVISIONS (WHETHER OF THE STATE OF NEW YORK OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK. IN FURTHERANCE OF THE FOREGOING, THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL CONTROL THE INTERPRETATION

AND CONSTRUCTION OF THIS AGREEMENT AND EACH OF THE OTHER TRANSACTION AGREEMENTS (AND ALL ANNEXES, SCHEDULES AND EXHIBITS HERETO AND THERETO), EVEN THOUGH UNDER THAT JURISDICTION'S CHOICE OF LAW OR CONFLICT OF LAW ANALYSIS, THE SUBSTANTIVE LAW OF SOME OTHER JURISDICTION WOULD ORDINARILY APPLY.

9Q. JURISDICTION AND VENUE. ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST VITALSTREAM WITH RESPECT TO THIS AGREEMENT OR ANY OTHER TRANSACTION AGREEMENT MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN NEW YORK CITY, NEW YORK. BY EXECUTING AND DELIVERING THIS AGREEMENT AND THE OTHER TRANSACTION AGREEMENTS TO WHICH THEY ARE A PARTY, VITALSTREAM AND EACH HOLDER OF CONVERTIBLE NOTES, WARRANTS OR UNDERLYING COMMON STOCK, ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER TRANSACTION AGREEMENTS. VITALSTREAM AND EACH HOLDER OF CONVERTIBLE NOTES, WARRANTS OR UNDERLYING COMMON STOCK HEREBY WAIVE ANY CLAIM THAT NEW YORK CITY, NEW YORK IS AN INCONVENIENT FORUM OR AN IMPROPER FORUM BASED ON LACK OF VENUE.

9R. WAIVER OF RIGHT TO JURY TRIAL. VITALSTREAM AND EACH HOLDER OF CONVERTIBLE NOTES, WARRANTS OR UNDERLYING COMMON STOCK HEREBY WAIVE, TO THE EXTENT PERMITTED BY APPLICABLE LAW, TRIAL BY JURY in any litigation in any court with respect to, in connection with, or arising out of this Agreement or any of the other Transaction Agreements or the validity, protection, interpretation, collection or enforcement hereof or thereof; AND VITALSTREAM HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE RIGHT TO INTERPOSE ANY SETOFF in connection with any such litigation, irrespective of the nature of such setoff except to the extent that the failure so to assert any such setoff would permanently preclude the prosecution of or recovery upon same. VITALSTREAM AGREES THAT THIS SECTION 9R IS A SPECIFIC AND MATERIAL ASPECT OF THIS AGREEMENT AND EACH OF THE OTHER TRANSACTION AGREEMENTS AND ACKNOWLEDGES THAT EACH HOLDER OF CONVERTIBLE NOTES, WARRANTS OR UNDERLYING COMMON STOCK WOULD NOT HAVE ENTERED INTO THIS AGREEMENT OR MADE AN INVESTMENT HEREUNDER IF THIS SECTION 9R WERE NOT PART OF THIS AGREEMENT AND THE OTHER TRANSACTION AGREEMENTS.

IN WITNESS WHEREOF, the parties have executed this Amended and Restated Convertible Note and Warrant Purchase Agreement as of the date first written above.
