Maguire -------------------------------- ------------------------ Title: Executive Vice Title: President & Chief Operating President--Strategic Officer of Large Accounts Development & Business Planning --------------------------------- ------------------------ Date: June 30, 2000 Date: June 30, 2000 -------------------------------- ------------------------ 16 <PAGE> SCHEDULE M-6.2 TO MASTER AGREEMENT SECURITY AGREEMENT 1. This Security Agreement Schedule ("Schedule") shall be governed by the terms and conditions of the Equipment Purchase Agreement ("Agreement") dated as of the 30th day of June, 2000, between Winstar Wireless, Inc. ("Winstar") and SAVVIS COMMUNICATIONS CORPORATION ("Customer"). Capitalized terms used in this Schedule that are not defined below shall have the meaning set forth in the Agreement. 2. Security Interest. As collateral security for all of Customer's payment obligations under the Agreement, Customer hereby grants Winstar a first priority security interest in all of the Radios purchased or to be purchased under the Agreement, to the maximum extent permitted by law (such items of collateral being collectively or individually, referred to as the "Security"). Customer shall, at Winstar's expense, take all commercially reasonable action required by Winstar to further evidence and/or perfect such security interest, including without limitation executing and delivering a separate security agreement and UCC-1 financing statements. In the event Winstar exercises its rights set forth below, Customer shall cooperate in good faith in assisting Winstar. 3. Remedies upon Default. (i) Upon the occurrence of any Event of Default that has not been cured Winstar shall have the right with or without legal process and with or without previous notice or demand for performance, to replevin, take possession and/or control of the Security or any part thereof (at the same or different times) and, generally, to exercise any and all rights, of any kind or nature, afforded to a secured party under the UCC, or other applicable law, or in equity. Without limiting the generality of the foregoing, Customer agrees that Winstar shall have the right upon nonpayment of any amounts due pursuant to this Agreement, and such nonpayment has not been cured, subject to notice in paragraph (ii) below and subject to the mandatory requirements of applicable law, to sell or otherwise dispose of all or any part of the Security at public or private sale for cash, upon credit or for future delivery as Winstar shall deem appropriate. Upon consummation of any such sale Winstar shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Security so sold. Each such purchaser at any such sale shall hold the property sold absolutely, free from any claim or right on the part of Customer it being understood that Customer shall retain the right to redeem the Security at any time prior to sale. (ii) Winstar shall give Customer 15 days' written notice (which Customer agrees is reasonable notice within the meaning of Section 9-504(3) of the UCC or its 17 <PAGE> equivalent in other jurisdictions) of Winstar's intention to make any sale of the Security, pursuant to paragraph (i) above. Such notice, in the case of a public sale, shall state the time and place for such sale. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as Winstar may fix and state in the notice of such public sale. At any such sale, the Security, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as Winstar may (in its sole and absolute discretion) determine. Winstar shall not be obligated to make any sale of any Security if it shall determine not to do so, regardless of the fact that notice of sale of such Security shall have been given. Winstar may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any part of the Security is made on credit or for future delivery, the Security so sold may be retained by Winstar until the sale price is paid by the purchaser or purchasers thereof, but Winstar shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Security so sold and, in case of any such failure, such Security may be sold again upon like notice. At any public (or, to the extent permitted by law, private) sale made pursuant to this Section, Winstar may bid for or purchase, the Security or any part thereof offered for sale and may make payment on account thereof by using any "Obligation" (defined as all present and future monetary obligations of Customer to Winstar under the Agreement) then due and payable to Winstar from Customer as a credit against the purchase price and Winstar may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to Customer therefor, provided that the purchase price paid by Winstar reflects at least the fair market value on the secondary market of the Security. For purposes hereof, a written agreement to purchase the Security or any portion thereof shall be treated as a sale thereof. As an alternative to exercising the power of sale herein conferred upon it, Winstar may proceed by a suit or suits at law or in equity to foreclose this Agreement and to sell the Security or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. (iii) In the event Winstar exercises this right in lieu of a sale of Security as provided above, then the amounts payable to Winstar which are in default shall be credited by an amount equal to the fair market value of such Security and Winstar shall retain its rights to pursue collection of any remaining unpaid amounts. 4. Application of Proceeds. Winstar shall apply the proceeds of any collection or sale of the Security, as well as any Security consisting of cash, as follows: FIRST, to the payment of all costs and expenses incurred by Winstar in connection with such collection or sale or otherwise in connection with this Agreement or any of the Obligations, including all court costs and the fees and expenses of its agents and legal counsel, the repayment of all advances made by Winstar hereunder 18 <PAGE> on behalf of Customer and any other costs or expenses incurred in connection with the exercise of any right or remedy hereunder; SECOND, to the payment in full of the Obligations; and THIRD, to Customer, its successors or assigns, or as a court of competent jurisdiction may otherwise direct. Winstar shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Schedule. Upon any sale of the Security by Winstar (including pursuant to a power of sale granted by statute or under a judicial proceedings), the receipt of sale from Winstar or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Security so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to Winstar or such officer or be answerable in any way for the misapplication thereof. 19 <PAGE> SCHEDULE M-6.3 ALLOCATION TABLE ---------------------------------------------------------------------------------------------------------------- Monthly Price 12 Months 10 Year Price Per Unit Quantity Total per Link Per Year Term ---------------------------------------------------------------------------------------------------------------- RADIO EQUIPMENT [***] 500 [***] ---------------------------------------------------------------------------------------------------------------- INSTALLATION [***] 500 [***] SERVICES ---------------------------------------------------------------------------------------------------------------- O&M [***] 12 10 [***] 500 [***] ---------------------------------------------------------------------------------------------------------------- BACKHAUL [***] 12 10 [***] 500 [***] ---------------------------------------------------------------------------------------------------------------- IN-BUILDING [***] 12 10 [***] 500 [***] ---------------------------------------------------------------------------------------------------------------- CENTRAL OFFICE [***] 12 10 [***] 30 [***] COLLOCATION ---------------------------------------------------------------------------------------------------------------- TOTAL [***] ---------------------------------------------------------------------------------------------------------------- [***] CONFIDENTIAL TREATMENT REQUESTED 20 <PAGE> EXHIBIT A TO MASTER AGREEMENT EQUIPMENT PURCHASE This Equipment Purchase Exhibit ("Exhibit") shall be governed by the terms and conditions of the Master Agreement ("Master Agreement") dated as of the 30th day of June 2000, between WINSTAR WIRELESS, INC.

However, Customer shall be required to maintain the Space in an orderly manner and shall be responsible for the removal of trash, packing, cartons, and related items from the Space. Further, Customer shall maintain the Space in a safe condition including, but not limited to, the preclusion of storing combustible materials in the Space. Winstar, however, will have no operations or maintenance responsibilities with respect to Customer's Equipment, except as such responsibilities pertain to the construction work, if specifically contemplated by this Agreement. (h) Unless otherwise provided in the Collocation Schedule, each visit by Customer to the Space will be deemed to utilize escort services furnished by Winstar from the time Customer's employee(s) sign(s) in upon entering the Terminal Facility to the time Customer's employee(s) sign(s) out upon leaving the Terminal Facility. (i) Customer acknowledges and agrees that it has been granted only a limited, non-exclusive license to occupy the Space for the period of time and under the terms and conditions set forth in the Transaction Documents and herein, and that it has not been granted any real property interests of any kind in the Space, Premises, or the Terminal Facility. (j) The Equipment shall remain Customer's exclusive personal property throughout the Term, and upon termination of this Exhibit, Customer shall have the right to remove all Equipment at Customer's sole expense on or before the expiration or earlier termination of this Exhibit; provided Customer repairs any damage to the Space, Premises or Terminal Facility caused by such removal.

(a) In addition to the collocation services provided above, Winstar shall make all reasonable efforts to provide Digital Subscriber Line Access Multiplexer ("DSLAM") service to Customer. (b) In providing DSLAM collocation to Customer, Winstar may, at its sole reasonable discretion, provide: (i) rack space at an Eligible Location for a multiplexer or (ii) a port within Winstar's own multiplexer located at the Eligible Location. (c) In deciding whether to offer DSLAM collocation to Customer, Winstar may consider its own business objectives with respect to space on a rack or ports in a multiplexer. 3.

In the event that Winstar's underlying leasehold interest in a Terminal Facility expires prior to the expiration of the Term, Winstar shall, at least one hundred twenty (120) days before the expiration of such leasehold interest, make a good faith effort to renew the underlying leasehold interest to allow Customer to continue to occupy the Space for the duration of the Term. (b) Upon termination or expiration of the license for each Space, Customer agrees to remove the Customer Equipment and other property that has been installed by Customer or Customer's agents (or by Winstar on behalf of Customer, if Winstar desires such Customer Equipment to be removed). In the event such Customer Equipment or property has not been removed within thirty (30) days after the effective termination or expiration date, then the Customer Equipment shall be deemed abandoned and Customer shall lose all rights and title thereto. 39 <PAGE> (c) In the event the Terminal Facility becomes the subject of a taking by eminent domain by any authority having such power, Winstar shall have the right to terminate the affected Collocation Schedule. Winstar shall give Customer prompt advance notice, to the extent practicable of important developments and the removal Schedule as it learns of the same. Customer shall have no claim against Winstar for any relocation expenses, any part of any award that may be made for such taking or the value of any unexpired term or renewed periods that result from a termination by Winstar under this provision, or any loss of business from full or partial interruption or interference due to any termination.

(c) Customer agrees to reimburse Winstar promptly for all repair or restoration costs associated with damage or destruction caused by Customer's personnel, Customer's agents, Customer's suppliers/contractors or Customer's visitors during the Term or as a consequence of Customer's removal of the Customer Equipment or property installed in the Space. 5. Additional Terms Governing Use of Collocation Space; Installation of Customer Equipment. (a) Before beginning any delivery, installation, replacement or removal work, Customer must obtain Winstar's written approval with respect to Customer's choice of suppliers and contractors, which approval shall not be unreasonably withheld. Winstar may request additional information before granting approval and may require reasonable scheduling changes and substitution of suppliers and contractors as conditions of its approval. Approval by Winstar is not an endorsement of Customer's supplier or contractor, and Customer will remain solely responsible for the selection of the supplier or contractor and all payments for construction work or any other work relating thereto. Notwithstanding any provision herein to the contrary, Winstar may, at its sole discretion, perform some or all of the work required in connection with the installation of Customer equipment, and Customer shall bear all reasonable costs in connection therewith. In the event Winstar performs any of the work required in connection with the installation of Customer equipment, Winstar shall send advance 40 <PAGE> notice to Customer's Chief Technology Officer via electronic mail or any other comparable communication device. (b) Customer shall not make any construction changes or material alterations to the interior or exterior portions of the Space, including any cabling or power supplies for the Customer Equipment, without obtaining Winstar's prior written approval for Customer to have the work performed or having Winstar perform the work.

(c) Customer's access to the Terminal Facility, use of the Space, installation of the Customer Equipment, and type of Customer Equipment installed, shall at all times be subject to Customer's adherence to generally accepted industry standards, rules and requirements of the Premises, security rules, and reasonable requirements and rules of conduct established by Winstar for the Terminal Facility and Space.

Customer shall not erect any signs or devices to the exterior portion of the Space without submitting the request to Winstar and obtaining Winstar's written approval which may be withheld in its sole discretion. (d) Customer may not provide, or make available to any third party, space within the Collocation Space without Winstar's prior written consent, which may be withheld in its sole discretion. If Customer should provide, or make available to any third party, space within the Space without obtaining the written consent of Winstar, Customer shall be in breach of this Exhibit and Winstar may pursue any legal or equitable remedy, including but not limited to the immediate termination of the license pursuant to Section 6 below. (e) Notwithstanding any other provisions of this Exhibit, Customer Equipment placed in the Space shall not interfere with or impair service provided by Winstar or by any other lessee of the Premises; shall not unreasonably disturb any other lessee of the Premises; shall not endanger or damage the facilities of Winstar or of any authorized user of the Space, or the Premises; shall not compromise the privacy of any communications carried in, from, or through the Premises; and shall not create an unreasonable risk of injury or death to any individual or to the public. Customer shall not improperly restrict or interfere with Winstar's network or the use thereof. Upon notice by Winstar, Customer shall promptly remove any hazard, interference, or service obstruction that may be caused by hardware, software or connectivity owned by or under the control of Customer. Nothing stated herein shall be construed to interfere with Customer's ability to comply with the rules, regulations or directives of any governmental or judicial authority.

(f) Winstar shall not arbitrarily or discriminatorily require Customer to relocate the Customer Equipment; however, upon sixty (60) days prior written notice or, in the event of an emergency, such time as may be reasonable, Winstar reserves the right to change the location of the Space or the Terminal Facility to a site which shall afford comparable environmental conditions for the Customer Equipment and comparable accessibility to the Customer Equipment. Winstar and Customer will work together in good faith to minimize any disruption to Customer's services as a result of such relocation. Winstar shall be responsible for the cost of improving the Space to which the Customer Equipment may be relocated, and for relocation of Customer Equipment interconnected to Winstar services, except that Winstar shall not be responsible for relocating facilities installed in violation of this Section 4. 6.

ASTERISKS DENOTE OMISSIONS. September 29, 2000 Mr. Bob Maguire President - COO Large Accounts Winstar Wireless, Inc. 685 Third Avenue 31st Floor New York, New York, 10017 Dear Bob: On June 30, 2000, SAVVIS Communications Corporation ("SAVVIS") and Winstar Wireless, Inc. ("Winstar") entered into a series of agreements (the "Agreements") pursuant to which SAVVIS and Winstar agreed to purchase and sell certain products and services between them. Among the Agreements entered into were a Master Agreement (the "Master Agreement"), a Professional Services Agreement (the "Professional Services Agreement"), as amended and a Basic Internet Services Agreement (the "BSA"). Capitalized terms used herein and not otherwise defined shall have the meanings given to such terms in the Agreements and the related exhibits. It is the intent of the parties to amend the Agreements in accordance with the terms of this letter. Pursuant to Exhibit A to the Master Agreement - Equipment Purchase, SAVVIS is obligated to purchase 500 radios pairs from Winstar during the Term. SAVVIS hereby agrees to accelerate the purchase of 106 radio pairs from Winstar as of the date hereof as evidenced by the Purchase Order attached hereto as Schedule A, such that subsequent to the date hereof, SAVVIS shall have acquired 310 of the 500 radio pairs it is obligated to purchase under the Master Agreement. SAVVIS shall be obligated to make payments with respect to such additional radio pairs as set forth on Schedule A; provided, however, that in the event Winstar has failed to install 175 radio pairs, which radio pairs have also been accepted by SAVVIS on or before October 1, 2001, then SAVVIS shall continue to make payments of [**] per quarter until such time as Winstar has installed and SAVVIS has accepted 175 radio pairs. At such time SAVVIS shall resume the payment schedule as set forth on Schedule A, provided that in the event that the 175 radio pairs were not installed and accepted by October 1, 2001 that amount paid to Winstar from October 1, 2001 until the 175 radio pairs were installed and accepted shall be offset against the future quarterly payment obligations. For example, if the 175 radio pairs were not <PAGE> installed and accepted until February 10, 2002, then the payment due to Winstar on March 1, 2002 shall be [**] (being [**] minus [**]). Section 3.2 of the Professional Services Agreement shall be amended to provide that Winstar shall request Services from SAVVIS in a minimum amount of [**] (the "Minimum") during calendar year 2001 which Services shall be provided to Winstar at the rate of at least [**] per quarter. To the extent that Winstar does not use Services in an amount equal to at least [**] per quarter, then SAVVIS shall invoice Winstar and Winstar shall be obligated to pay such amounts. In the event that Winstar fails to use Services in the year 2001 in an amount equal to the Minimum, then SAVVIS shall invoice Winstar at the end of calendar year 2001 in an amount equal to the difference between the Minimum and that amount previously billed by SAVVIS during calendar year 2001. The parties shall amend the BSA to provide that Winstar shall acquire from SAVVIS an additional [**] in Frame Services and IP Services at the prices as are set forth in the BSA. Such amount shall be prepaid to SAVVIS and shall be due and owing to SAVVIS on October 2, 2000. Section 6 of the Master Agreement shall be amended to provide that SAVVIS shall, at its option, have a right of offset with respect to any amounts due and owing to Winstar for the Equipment if, and to the extent, Winstar fails to pay any amounts to SAVVIS under the Professional Services Agreement. The parties agree that they shall amend the Agreements as set forth above but that it is the intent of the parties that the amendments described herein shall be binding on the parties as of the date hereof.
