CREDIT AGREEMENT THIS CREDIT AGREEMENT is entered into as of June 17, 1998 by and between Motorola Inc., a Delaware corporation, (hereinafter "Motorola") and ARDIS Company, a New York general partnership (the "Borrower" or "you"). You have asked Motorola to provide financing to you (the "Credit") for the purchase of certain equipment from Motorola. Motorola is willing to provide the Credit on the terms and conditions set forth in this Credit Agreement and the attached Exhibits, which are part of this Credit Agreement. The terms and conditions ("Terms and Conditions") attached to this Credit Agreement as Exhibit "A" include definitions for many of the terms used below. 1. Amount of Credit; Note. The aggregate maximum principal amount of ----------------------- Credit that may be drawn under this Credit Agreement shall be $10,000,000. You may obtain Advances under this Credit Agreement until June 16, 2000, if, at the time of requesting an Advance, you have complied with all Requirements for Advances. Amounts repaid under this Credit Agreement may not be re-borrowed. Motorola shall have no obligation, express or implied, to extend or to grant additional credit after this Credit Agreement expires. The Credit shall be evidenced by a promissory note ("Note") in substantially the form attached as Exhibit "B" duly executed on behalf of the Borrower. 2. Drawdown Procedure. At the time you order equipment from Motorola, ------------------- you will notify Motorola in writing on the purchase order that you intend to finance the purchase with Motorola under this Credit Agreement, and will identify the location (by State and county) at which each item of equipment may be located during the term of this Agreement. By issuing that notice you will be deemed to represent and warrant that all prior statements of your account are correct. Upon shipment of each such item of equipment, provided that all Requirements for Advances have been satisfied, if the Requirements for Advances have been satisfied, Motorola shall thereupon be deemed to have made an Advance equal to 75% of the purchase price of such item of equipment, and Motorola shall make a notation on its books and records, and on the schedule to the Note, showing such Advance. On each Quarterly Date during the term of this Credit Agreement, the aggregate amount of the Advances made since the date hereof, or if later, since the date of the most recent Quarterly Date, shall constitute a Loan, which shall bear interest at the Applicable Rate and amortize as set forth herein. You hereby irrevocably authorize Motorola at any time to endorse on the Note (or record on its books and records) the date and amount of any Advances made by Motorola to you, the outstanding balance of all Advances and Loans at any time and each payment and prepayment of any principal plus interest accruing thereon. Such endorsement or record shall be prima facie evidence of the principal amount owing on the Note in any proceedings to enforce the payment thereof; provided, that failure to record an Advance or any erroneous recordation shall not affect Borrower's obligations to repay all sums actually borrowed hereunder. No Advance or deemed Advance shall be permitted for any payment of principal or interest due under the Note. You will receive from Motorola, on or about the Thursday immediately preceding the last Monday of the month, an itemized list of equipment provided to you during the most recent monthly period. You will pay to Motorola, within thirty days from the invoice date, the full amount of the purchase price for equipment and services shown on such invoice, less the amount of any Advances made for the purchase of any such equipment as provided above. 3. Interest Rate. You agree to pay interest to Motorola on the -------------- principal amount of the Credit outstanding from time to time. If the Credit is not in Default, you will pay interest each quarter in arrears at the Applicable Rate. If, and as long as, the Credit is in Default, the interest rate will be increased another three percent (3%) per annum above the Applicable Rate (the "Default Rate") and will be payable upon demand. As detailed in the Terms and Conditions, under no circumstances will you be required to pay an interest rate or an amount of interest greater than the maximum interest allowed by applicable law. 4. Repayment Terms. Motorola will send you quarterly invoices --------------- showing principal and interest due. You agree to pay each invoice on or before its due date. The principal portion of each Loan will be amortized over a three year period beginning with the Quarterly Date on which such Loan commences, in twelve consecutive equal quarterly installments. You agree to pay a late charge equal to five percent (5%) of any principal amount payable by you for any invoice payment not received by Motorola within ten days of the due date. Your failure to pay an invoice within fifteen days of its due date constitutes an Event of Default under this Credit Agreement. 5. Financial Information. Motorola has agreed to provide the Credit --------------------- based on financial information you have prepared and supplied. Between the date of the financial information and the date of this Credit Agreement, you confirm that there has been no material, adverse change in your financial condition or business operation. As described in the Terms and Conditions, you agree to give Motorola updated financial information during the time the Credit is outstanding. 6. Collateral. As security for the timely payment and performance of ---------- your Obligations, you hereby grant to Motorola a perfected, first priority security interest and lien in the Collateral. At the time of delivery of each purchase order as described in Section 2 above, you will deliver to Motorola an executed Financing Statement on form UCC-1 substantially in the form of Exhibit "E" to this Agreement for filing in each jurisdiction identified as a location where the equipment ordered may be located during the term of the Agreement. You hereby authorize Motorola to attach to each such Financing Statement a schedule listing the serial numbers or other identifying information describing the equipment shipped in accordance with the purchase order, and to file such Financing Statements in each jurisdiction in which it deems such filing necessary to perfect Motorola's security interest in the Collateral. You agree to execute such other documents and take all reasonable actions requested by Motorola, at your expense, to perfect and maintain the perfection of Motorola's security interest in the Collateral. The Credit will also be secured by the joint and several Guarantees of the Guarantors listed on Exhibit "C", guaranteeing repayment of the Credit (in accordance with Guarantee Agreements in the form attached as Exhibit "C"). 7. Waiver of Jury Trial. YOU AND MOTOROLA AGREE THAT ANY CLAIM, ---------------------- COUNTERCLAIM, SETOFF, OR DEFENSE RELATING IN ANY WAY TO (A) THIS AGREEMENT (INCLUDING ALL EXHIBITS AND ALL OTHER DOCUMENTS RELATING TO THIS AGREEMENT), OR (B) ANY ACTION, OMISSION, COURSE OF CONDUCT, PRACTICE, OR TRANSACTION BY YOU OR MOTOROLA (INCLUDING THE RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS, AND OTHER REPRESENTATIVES OF EACH) SHALL BE HEARD AND DETERMINED BY A COURT WITHOUT A JURY. YOU AND MOTOROLA HAVE ENTERED INTO THIS AGREEMENT IN RELIANCE UPON THIS PROVISION AS A MATERIAL TERM OF THE CREDIT. 8. Governing Law. Motorola's headquarters are in Schaumburg, Illinois; ------------- this Credit Agreement will, if accepted and executed by Motorola, become a contract in the State of Illinois and be governed by the law of Illinois, without regard to its conflicts of law rules. Upon the occurrence of any Event of Default, however, Motorola shall also have the right to enforce this Credit Agreement and related collateral documents in accordance with the laws of any jurisdiction in which an Obligor or Collateral may then be located, or in which the law permits Motorola to bring suit. 9. No Other Agreements; Complete Review. You and Motorola acknowledge ------------------------------------- and agree that this Credit Agreement and the other documents executed pursuant to this Agreement collectively comprise the complete written agreement regarding the Credit; there are no other understandings, inducements, representations, negotiations, or promises of any kind other than those written here and those made a part of this Credit Agreement. You and Motorola also acknowledge that they have reviewed, with their own attorneys if desired, all the terms, conditions, and provisions of this Credit Agreement and the attached Exhibits. 10. Limitation on Liability. In no event shall Motorola have any ----------------------- liability under or in connection with this Credit Agreement or any exhibit hereto for special, incidental, indirect, or consequential damages of any sort, including (without limitation) lost profits. If you have previously obtained financing from Motorola or otherwise purchased equipment or services from Motorola: (a) you hereby release Motorola and its officers, directors, and employees from and against any claim, counterclaim, defense, setoff, or other liability with respect to any transaction, course of dealing, or other matter that arose or occurred before you signed this Credit Agreement, and (b) you acknowledge that any prior credit terms or agreements, whether written or oral (but excluding any open account arrangements), have now been superseded and replaced by this Credit Agreement. 11. Absolute Obligation. ANY PRESENT OR FUTURE LAW TO THE CONTRARY NOTWITHSTANDING, YOUR OBLIGATION TO PAY MOTOROLA ALL AMOUNTS DUE HEREUNDER IS ABSOLUTELY UNCONDITIONAL. YOU SHALL NOT BE ENTITLED TO ANY ABATEMENT, REDUCTION, SETOFF, COUNTERCLAIM, DEFENSE, INTERRUPTION, DEFERMENT, RECOUPMENT OR DEDUCTION WITH RESPECT TO ANY PRINCIPAL OR INTEREST PAYMENT OR ANY OTHER SUM PAYABLE HEREUNDER, NO MATTER HOW, WHEN OR AGAINST WHOM ASSERTED, ARISING OR CLAIMED, NOR SHALL ANY OF YOUR OBLIGATIONS HEREUNDER BE AFFECTED FOR ANY REASON WHATSOEVER. The foregoing shall not be deemed to amend or limit your right to make a claim against Motorola for any obligation or liability that Motorola may otherwise have to you under the Purchase Agreement. 12. Confidentiality. Neither you nor Motorola will disclose this Credit --------------- Agreement or its terms to a third party except (a) insofar as the third party has a "need to know" (as in the case of a party's accountants), in which case the third party will be instructed to abide by this Paragraph 10, (b) in the event disclosure is necessary to enforce the Credit Agreement or is compelled by subpoena, requirement of law, or order of a court of competent jurisdiction, or (c) by prior written consent of both parties.
