Cisco Systems [LOGO](TM) Capital December 2, 1999 CAIS, Inc. 1255 22nd Street NW Fourth Floor Washington D.C. 20037 Attn: Barton Groh Dear Mr. Groh: Reference is made to the Agreement dated as of June 30, 1999 (as amended, modified, renewed or extended from time to time, the "Credit Agreement"), between CAIS, Inc. ("Borrower") and Cisco Systems Capital Corporation ("Lender"), the terms defined therein being used herein as therein defined. 1. Lender has recently conducted a review of its procedures and policies regarding Loan fundings and interest rate calculations under the vendor credit facilities to which it is a party, including the Agreement, and as a result of such review wishes to propose certain changes to the Agreement and Notes. The Lender wishes to clarify the advance notice requirements and funding procedures in connection with the Credit Agreement, and, accordingly, proposes that Section 2.3 of the Credit Agreement be amended and restated in its entirety to read as follows: 2.3 Borrowing Procedure. Each Loan to be made hereunder shall be ------------------- in such minimum principal amount as shall be specified in the Schedule and shall be subject to five Banking Days' advance written notice, or telephonic notice (confirmed immediately in writing). Each such written notice of borrowing shall be in substantially the form of Exhibit A (with appropriate --------- completions). Upon fulfillment of the applicable conditions set forth in Section 3.1 and 3.2, and subject to the Funding Procedures and Policies (as defined below), Lender shall make the proceeds of the Loan available in accordance with the Borrower's payment instructions. Without limiting the generality of the foregoing, in the case of any Loan made hereunder for the purpose of paying the purchase price of Cisco Products, (i) Lender shall make the Loan available directly to the Vendor, and (ii) if the Vendor is Cisco Systems, each such Loan shall be deemed to be outstanding hereunder and under the Note evidencing such Loan effective as of the date 30 days after the invoice date of the Cisco Products which are being financed by such Loan (or on such date thereafter as Cisco Systems shall agree to <PAGE> in its sole discretion), and Lender is hereby authorized to make such Loans without being required to receive a notice of borrowing with respect thereto. Borrower hereby authorizes and directs Lender to make direct payment to any Vendor and any other intended recipient, if any, of Loan proceeds. Lender will make loan proceeds available to any Vendor or other recipient thereof on or not later than five Banking Days following the requested Borrowing Date. As used herein, "Funding Procedures and Policies" means the Lender's "Funding Procedures and Policies" as in effect from time to time, as communicated to Borrower. Lender will be quoting LIBOR on a calendar quarter basis and adjusting the rounding convention it uses in determining LIBOR. Accordingly, Lender proposes that the fourth paragraph of each Note be amended and restated in its entirety to read as follows, effective as of the beginning of the current calendar quarter: The period between the date of a Loan and the Maturity Date shall be divided into successive periods, each such period being an "Interest Period" for purposes of this Promissory Note. The initial Interest Period for a Loan shall begin on the date such Loan is made and end on the next Quarterly Date. Each subsequent Interest Period shall begin on the last day of the immediately preceding Interest Period and shall end on the next succeeding Quarterly Date. As used herein, "LIBOR" means for any Interest Period the rate of interest per annum determined by Lender to be the rate of interest per annum (rounded upward, if necessary, to the nearest 1/100 of 1%) for deposits in Dollars for three months appearing on the display page designated as "3750" in the Dow Jones Market Service (formerly known as the Telerate Service), or any replacement page thereof in the Dow Jones Market Service displaying London interbank offered rates of major banks for Dollar deposits, at or about 11:00 a.m. (London time) on the second Banking Day preceding the first day of the applicable calendar quarter in which such Interest Period occurs, provided that if no, or only one, such offered quotation appears on such Telerate display page (or such other replacement page), "LIBOR" shall be determined by reference to the Reuters Screen LIBO Page of the Reuters Monitor Money Rates Service (or any replacement page thereof or other applicable Reuters display page) or other comparable source of interest quotations for such interbank rates selected by Lender; and "Quarterly Date" means the last day of each calendar quarter. 2. Borrower has requested that Lender agree to the following amendments to the Credit Agreement. Lender has agreed to such request, subject to the terms and conditions hereof. (a) The Schedule of Information to the Credit Agreement shall be amended and restated in its entirety as set forth on Exhibit A attached hereto. --------- (b) Exhibit A to the Credit Agreement shall be amended and restated in its entirety as set forth on Exhibit B attached hereto. --------- <PAGE> (c) The attached promissory notes, set forth on Exhibit C and Exhibit D --------- --------- attached hereto (reflecting the amendments contemplated herein), shall be substituted for the promissory notes previously executed and delivered by Borrower. (d) Exhibit E to the Credit Agreement shall be amended and restated in its entirety as set forth on Exhibit E attached hereto. --------- 3. Borrower has requested that Lender waive the requirement set forth in Section 5.1(q) of the Credit Agreement. Lender has agreed to such request, provided that no lock box or collection account is established in favor of Nortel under the Nortel Credit Agreement. Notwithstanding the foregoing, if Borrower shall at any time establish a lock box or collection account in favor of Nortel, Borrower shall within 30 days of the effectiveness thereof, fully comply with the requirements set forth in Section 5.1(q). Except as provided above, the Credit Agreement and other Loan Documents remain unmodified and in full force and effect. Please indicate the agreement of Borrower and Guarantor to the foregoing by signing and returning to Lender, to the attention of our legal counsel, Bernice Lake, Esq., a counterpart of this letter. We look forward to receiving your response. Please contact Bernice Lake at your earliest convenience on tel. (415) 442-1753 at fax (415) 442-1010 or via email at blake@brobeck.com, if you have any questions or comments regarding the above matters. Thank you in advance for your cooperation.

In the event that any amount of principal hereof or interest thereon, or any other amount payable hereunder or under the Credit Agreement, shall not be paid in full when due (whether at stated maturity, by acceleration or otherwise), Borrower shall pay interest on such unpaid amount to Lender, from the date such amount becomes due until the date such amount is paid in full, payable on demand of Lender, a fluctuating rate per annum equal at all times to the Prime Rate (as defined below) plus 8% per annum.
