EXHIBIT 10.22 CREDIT FACILITY AGREEMENT AND PROMISSORY NOTE This CREDIT FACILITY AGREEMENT (the "Agreement") is made as of February 3, 2000 between Netrix Corporation (the "Borrower") and Steven T. Francesco (the "Lender"). SECTION 1. AMOUNT AND TERMS OF THE CREDIT FACILITY 1.1 THE CREDIT FACILITY Subject to the terms and conditions of this Agreement and the Note (as such term is defined in Section 1.2 below), the Lender agrees to make available to the Borrower a credit facility (the "Facility") under which the Borrower may from time to time on or after the date hereof to and including the Expiration Date (as such term is defined in Section 2.3 below) borrow from the Lender any amount up to but not to exceed $10,000,000 in the aggregate at any one time outstanding (exclusive of interest, fees or other charges payable by the Borrower under this Agreement and Note). Borrowings under the Facility are herein referred to collectively as the "Loans" and individually as a "Loan". The Borrower may use the Facility by borrowing, repaying and reborrowing in accordance with the terms and conditions of this Agreement and the Note. Each request for a Loan may be made upon ten business days' notice. Each Loan shall be deemed to be a representation and warranty by the Borrower on the date of such Loan that immediately prior to and after the making of such Loan (i) no Event of Default (as described in Section 2.1 below), or event which, with the giving of notice or lapse of time or both, would become such an Event of Default, shall have occurred and be continuing and (ii) no material adverse change in the financial condition, assets, business, operations or prospects of the Borrower shall have occurred, and the truth and correctness of each of the foregoing representations when deemed made is a condition precedent to the Lender's obligation to make such Loan. 1.2 THE NOTE On or prior to the date on which the Lender makes the initial Loan to the Borrower under the Facility, the Borrower shall execute and deliver to the Lender the promissory note (the "Note") which follows this Agreement. The initial Loan and all subsequent Loans, and each payment made on account of the principal thereof, shall be endorsed on the Note as of the date such Loan is made or such payment is received by the Lender in immediately available funds as provided in the Note. The Note shall be used to record all Loans and payments of principal made under the Facility. 1.3 VOLUNTARY PREPAYMENTS The Borrower may prepay the Note in whole at any time or in part from time to time without premium or penalty. Partial prepayments of the Note shall be in a minimum principal amount of $10,000 or any whole multiple thereof. 1.4 FINANCIAL INFORMATION The Borrower hereby agrees to provide such financial information to the Lender as the Lender may reasonably request from time to time. SECTION 2. TERMINATION OF THE FACILITY 2.1 EVENTS OF DEFAULT If the Borrower fails to perform any agreement herein contained or contained in any other agreement with the Lender or if default occurs in the punctual payment of any sum payable under the Note, this Agreement or any other obligation of the Borrower to the Lender, or if any representation or warranty deemed made pursuant to Section 1.1 above shall be untrue or incorrect in any respect, or if any event described in paragraph 3 of the Note occurs; then the Facility shall automatically terminate and all Loans, although not yet due, shall become immediately due and payable without notice or demand. 2.2 TERMINATION OR REDUCTION OF COMMITMENT The Borrower shall have the right, upon prior written notice to the Lender, to terminate the Facility in whole at any time or to reduce the amount of the Facility provided in Section 1.1 in part from time to time, provided that (a) any termination of the Facility shall be accompanied by payment in full of the unpaid principal amount of the Note, together with interest accrued thereon, and (b) partial reductions of the Facility shall be in the minimum amount of $25,000, and shall be accompanied by prepayment, together with interest accrued thereon to the date of the prepayment, to the extent, if any, that the aggregate unpaid principal amount of the Note exceeds the Facility as then reduced. 2.3 EXPIRATION DATE Unless specifically extended by the Lender in writing or otherwise terminated under Section 2.1 or Section 2.2, the Facility shall expire on the earlier of (x) May 30, 2001 or (y) the date Borrower raises $10.0 million or more through the sale of equity securities (the "Expiration Date"), and all amounts outstanding under this Agreement and the Note shall be due and payable on the Expiration Date. SECTION 3. MISCELLANEOUS 3.1 NO WAIVER The Borrower agrees that no failure to exercise and no delay in exercising, on the part of the Lender, any right, power or privilege under this Agreement or the Note shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege under this Agreement or the Note preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies provided under this Agreement and the Note are cumulative and not exclusive of any rights or remedies provided by law. No modification or waiver of any provision of this Agreement or the Note, or any consent to any departure by the Borrower from the provisions hereof or thereof, shall be effective unless the same shall be in writing from the Lender and then such waiver or consent shall be effective only in the specific instance and for the purpose for which it is given. No notice to the Borrower shall entitle the Borrower to any other or further notice in other or similar circumstances unless expressly provided for herein. No course of dealing between the Borrower and the Lender shall operate as a waiver of any of the rights of the Lender under this Agreement or the Note. 2 3.2 SUCCESSORS AND ASSIGNS The Lender may at any time and from time to time sell, assign, transfer or otherwise dispose of all or any portion of this Agreement, the Note or the Lender's interest herein and the Lender may furnish any information concerning the Borrower in the possession of the Lender from time to time to its transferees or assignees (including prospective transferees or assignees). The Borrower may not assign or transfer its rights or obligations hereunder without the prior written consent of the Lender. 3.3 EXPENSES The Borrower agrees to reimburse the Lender on demand for all costs, expenses and charges (including, without limitation, fees and charges of counsel and costs allocated by internal legal counsel) in connection with the preparation or modification of this Agreement and the Note; the performance, collection or enforcement of this Agreement or the Note; or, the defense or prosecution of any rights of the Lender pursuant to this Agreement or the Note. 3.4 GOVERNING LAW This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Virginia. 3.5 NOTICE All notices, requests, demands, claims and other communications hereunder shall be in writing.
