UPI may terminate the licenses granted to AT&T and its Affiliates under Section 2 only by giving written notice to AT&T following the occurrence of a substantial and material breach of this Agreement by AT&T that: (a) is not cured in all material respects within ninety (90) days after the date on which AT&T receives written notice from UPI of such breach; and (b) is thereafter established by written order of an arbitrator (e.g., pursuant to Section 9) or a court of competent jurisdiction to be a substantial and material breach of this Agreement; and (c) is of such a nature that UPI cannot thereafter be reasonably made whole through and award of monetary damages (as determined by the arbitrator or court under (b) PAGE 13 <PAGE> above); provided that UPI is paid such monetary damages within fifteen (15) days after the issuance of the written order specified in (b) above, together with interest on such amount due from the date of the breach at a rate equal to the lesser of one and one-half percent (1.5%) per month or the maximum rate permitted by applicable law.

At AT&T's option, all copies of the UPI Software and the Application Server Software required to be delivered to UPI may be destroyed by AT&T, in which case AT&T will provide to UPI written certification that such destruction has been completed. 8.4 Effect of Termination of Term In the event AT&T, based on the occurrence of a Minor Release Event, enforces its rights under paragraph 6.2 and the Escrow Agreement, terminates the Term under paragraph 8.2.1 and continues to exercise the license rights granted under Section 2, AT&T will continue to pay usage fees to UPI at a rate equal to [*******************] of the amount that would otherwise be payable under paragraph 5.2.

All terms defined in the Software Agreement shall have the same meanings when used in this Escrow Agreement with initial letters capitalized. B. Pursuant to paragraph 6.2 of the Software Agreement, UPi must prepare and deliver to the Escrow Agent to be held in escrow a complete, current and accurate copy of all the UPI Software Source Code and the Application Server Software Source Code.

AGREEMENT UPI, AT&T and Agent therefore agree as follows: 1.

UPI shall also promptly deposit with Agent, and Agent shall accept from UPI, for storage purposes only, all other UPI Software or Application Server Software code required to be deposited in escrow by UPI under paragraph 6.2 of the Software Agreement.

UPI may withdraw its Dispute Notice at any time by giving Agent and AT&T written notice of such withdrawal. 8. Arbitration 8.1 General Any dispute of a Release Notice pursuant to paragraph 7.4 shall be settled by final and binding arbitration in accordance with the provisions of this section. The sole issue to be decided in any such arbitration shall be whether any Release Event has occurred. PAGE 3 <PAGE> 8.2 Notice If, within fifteen (15) days after receipt of any notice from Agent that it has received a Dispute Notice, the dispute has not been resolved in a mutually acceptable manner, either party may initiate the arbitration procedure under this section by giving the other party written notice demanding arbitration of the dispute. 8.3 Arbitration Unless otherwise agreed by UPI and AT&T, any dispute submitted to arbitration under this section shall be presented to a panel of three arbitrators. The party demanding arbitration under paragraph 8.2 shall appoint and specify one of the arbitrators in its notice demanding the arbitration. The other party shall appoint a second arbitrator and give the demanding Party written notice of such appointment within thirty (30) days after the notice demanding the arbitration. The two arbitrators so appointed shall appoint a third arbitrator who shall act as chairman of the arbitration panel. If the two arbitrators appointed by the parties do not agree upon the third arbitrator within thirty (30) days after appointment of the second arbitrator, then, upon request of UPI or AT&T, the third arbitrator shall be appointed in accordance with the Arbitration Rules of the Judicial Arbitration and Mediation Services, Inc. (J.A.M.S.). If any arbitrator is unable to serve as an arbitrator, then a substitute arbitrator shall be promptly designated by the person or persons who appointed the arbitrator who is unable to serve. 8.4 No Ex Parte Discussions No party may discuss the dispute to be arbitrated with any arbitrator after such arbitrator is appointed and prior to the arbitration panel's determination, without providing the other party with reasonable advance notice and the opportunity to participate in such discussions. 8.5 Procedures The arbitration shall be conducted in accordance with the Arbitration Rules of J.A.M.S. Additional rules of procedure for the conduct of the arbitration may be determined by a majority of the arbitrators. Such rules of procedures shall direct the expeditious evaluation of the merits of the dispute and rendering of a decision consistent with the complexity of the dispute being arbitrated. In any arbitration, each party shall have: (a) full access to the records of the other parties that pertain to the dispute; (b) the power to call for testimony of any director, officer, employee, agent or representative of the other parties; and (c) all other rights of discovery accorded to parties in civil actions under the Federal Rules of Civil Procedure (or rules or laws applicable to court proceedings adopted in lieu thereof) applicable in proceedings before the court specified in section 9.8. 8.6 Decision Unless otherwise agreed by UPI and AT&T, the arbitrators shall render a decision determining whether the Release Event has occurred within thirty (30) calendar days after completion of the arbitration proceeding. The decision of the arbitration panel shall be made by a majority of the arbitrators and shall be binding upon the parties. PAGE 4 <PAGE> 8.7 Location Any arbitration hearings under this Agreement shall be held at a mutually acceptable location in or near San Francisco, California, U.S.A. 8.8 Jurisdiction The Superior Court of the State of California in and for the City and County of San Francisco, shall be the forum for any court supervision of any arbitration under this section. 8.9 Costs Each party shall pay for the services and expenses of the arbitrator appointed by it. The costs for the services and expenses of the third arbitrator and all administration costs of the arbitration shall be paid by the non- prevailing party. 9. Interpleader Notwithstanding any other provision of this Agreement, if Agent receives a Release Notice and Agent is uncertain whether the Release Notice was timely or otherwise effective, then Agent may, in its sole discretion, begin an interpleader action and deposit the Deposit with the clerk of the court or withhold release of the Deposit until instructed otherwise by court order. In connection with any such deposit, Agent shall seek an appropriate order to seal the deposit so as to prevent release or disclosure to third parties. 10. Fees AT&T shall pay to Agent the initial and annual fees prescribed on the attached Exhibit I for performance of services by Agent during the Term. Agent may change its rates from time to time by providing at least sixty (60) days' advance written notice of such change to AT&T. 11. No Duty to Inquire Into Truth, Authenticity or Authority; Right to Require Additional Documents Agent shall not be required to inquire into the truth of any statements or representations contained in any notices, certificates or other documents required or otherwise provided hereunder, and shall be entitled to assume that the signatures on such documents are genuine, that the persons signing on behalf of any party thereto are duly authorized to execute the same, and that all actions necessary to render any such documents binding on the party purportedly executing the same have been duly undertaken. Without in any way limiting the foregoing, Agent may in its discretion require from UPI or AT&T additional documents which it deems to be necessary or desirable in the course of performing its obligations hereunder. 12. Indemnification Agent shall be responsible to perform its obligations under this Agreement and to act in a reasonable and prudent manner with regard to the escrow arrangement set forth herein. Provided Agent has acted in the manner stated in the preceding sentence, AT&T and UPI each agree to indemnify, defend and hold harmless Agent from any and all claims, actions, damages, arbitration fees and expenses, costs, attorney's fees and other liabilities incurred by Agent relating in any way to the escrow arrangement set forth in this Agreement.

RECITALS A. UPI and AT&T have entered into a Software License and Support Agreement, dated as of May 1, 1996 (the "Software Agreement"). All terms defined in the Software Agreement shall have the same meanings when used in this Escrow Agreement with initial letters capitalized. B. Pursuant to paragraph 6.2 of the Software Agreement, UPI must prepare and deliver to the Escrow Agent to be held in escrow a complete, current and accurate copy of all the UPI Software Source Code and the Application Server Software Source Code. E. UPI and AT&T desire to appoint Agent to act as the Escrow Agent to receive, hold and release the UPI Software Source Code and the Application Server Software Source Code pursuant to the Software Agreement in accordance with the terms, conditions and provisions set forth in this Escrow Agreement. AGREEMENT UPI, AT&T and Agent therefore agree as follows: 1. Appointment UPI and AT&T hereby appoint Agent, and Agent hereby accepts appointment, to act as the "Escrow Agent" contemplated by the Software Agreement. 2. Deposit Upon execution of this Escrow Agreement and thereafter within three (3) days after any Enhancement is delivered to AT&T, UPI shall deposit with Agent, and Agent shall accept from UPI, for storage purposes only, a complete, current copy of all UPI Software Source Code and Application Server Software Source Code to be held in escrow pursuant to this Escrow Agreement. Further, if UPI thereafter makes any material revision, supplement, improvement, addition, update or new version to any UPI Software Source Code or the Application Server Software Source Code, as the case may be, during the Term relating to an executable version that is generally provided to licensees of the UPI Software or Application Server Software without additional charge, UPI shall promptly deposit with Agent, and Agent shall accept from UPI, for storage purposes only, a complete, current copy of the same to be held in escrow pursuant to this Escrow Agreement, whereupon UPI may remove from the Deposit any UPI Software Source Code or Application Server Software Source Code, as the case may be, that is replaced or superseded by newly deposited items. UPI shall also promptly deposit with Agent, and Agent shall accept from UPI, for storage purposes only, all other UPI Software or Application Server Software code required to be deposited in escrow by UPI under paragraph 6.2 of the Software Agreement. The items deposited in escrow under this Escrow Agreement are sometimes collectively referred to herein as the "Deposit". PAGE 1 <PAGE> 3. Deposit List Upon each deposit under paragraph 2, UPI shall furnish to Agent a complete, current list ("Deposit List"), identifying all of the items contained in the Deposit, together with a written certification by an authorized agent of UPI that: (a) the Deposit List is accurate; and (b) a complete master, reproducible copy Of each item on the Deposit List is in the Deposit. Each time that UPI deposits any items pursuant to paragraph 2, Agent shall prepare and deliver to UPI a written receipt for the same. Promptly after each deposit, Agent shall deliver to AT&T a copy of the Deposit List and certification furnished by UPI and a copy of the receipt prepared by Agent. 4. Responsibility for Accuracy and Completeness Agent shall not be required to determine the accuracy or completeness of any deposit under paragraph 2 or any Deposit List furnished by UPI under paragraph 3. Further, Agent shall not be responsible for any items not actually deposited with it, whether or not such items were required to be deposited under the terms of this Escrow Agreement, the Software Agreement or any other agreement. 5. Retention and Release of Deposit Agent shall hold in safekeeping and preserve in confidence the Deposit during the Term and shall release or disclose the Deposit only in accordance with the terms of this Agreement. 6. Release of Deposit Agent shall release the Deposit only as follows: (a) Agent shall release the Deposit to UPI or AT&T upon Agent's receipt of written instructions to do so signed by an officer of each of UPI and AT&T; provided that all fees payable to Agent for performance of its services hereunder have been fully paid. (b) Agent shall release the Deposit to UPI at any time that Agent ceases doing business or is unable to hold the Deposit in accordance with the terms of this Agreement due to forces beyond its reasonable control; provided that all fees payable to Agent for performance of its services hereunder have been fully paid, and provided further that Agent gives such advance notice to UPI and AT&T as is reasonably practicable in the circumstances. Upon such notice, UPI and AT&T shall use their best efforts to agree upon a substitute escrow agent and enter into an escrow agreement containing substantially the same terms as this Escrow Agreement pursuant to which UPI shall deliver the Deposit to the substitute escrow agent. (c) Agent shall release the Deposit to AT&T on the eleventh (11th) day after Agent gives UPI a written Release Notice therefor pursuant to paragraph 7.3, provided that Agent does not receive a Dispute Notice from UPI in the manner and within the time specified in paragraph 7.4. (d) Agent shall release all or a portion of the Deposit in accordance with any arbitration award pursuant to Section 8 determining that a Release Event as to the UPI Software or the Application Server Software, as the case may be, has occurred, but in no event less than ten (10) days following such award. PAGE 2 <PAGE> (e) Agent shall release the Deposit to such persons and in such manner as may be directed by order of any court of competent jurisdiction pursuant to Section 9 or otherwise. (f) Upon the termination or expiration of the Term pursuant to Section 13, Agent shall release the Deposit to UPI or, if directed in writing signed by an officer of UPI and an officer of AT&T, to a substitute escrow agent. 7. Release Events 7.1 Release Events AT&T shall be entitled to release of the Deposit upon the occurrence of a Release Event. 7.2 Release Notice Upon the occurrence of any Release Event, AT&T may deliver to Agent a written notice (the "Release Notice") of the Release Event and requesting release of the Deposit as provided for in paragraph 7.1. The Release Notice must contain a statement, verified by an officer of AT&T, that the applicable Release Event has occurred and that the Deposit is to be released. 7.3 Agent's Notice to UPI Upon receipt of a Release Notice, Agent shall promptly give UPI written notice of such receipt and transmit with such notice a copy of the Release Notice. 7.4 Dispute UPI may dispute a Release Notice at any time within ten (10) days after UPI receives written notice thereof pursuant to paragraph 7.3, by giving written notice to Agent specifically denying the occurrence of such Release Event and setting forth a description of any facts that indicate that the Release Event did not occur (the "Dispute Notice"). 7.5 Agent's Notice to AT&T Upon receipt of a Dispute Notice, Agent shall promptly give AT&T notice of such receipt and transmit with such notice a copy of the Dispute Notice. 7.6 Withdrawal of Notice AT&T may withdraw its Release Notice at any time by giving Agent and UPI written notice of such withdrawal. UPI may withdraw its Dispute Notice at any time by giving Agent and AT&T written notice of such withdrawal. 8. Arbitration 8.1 General Any dispute of a Release Notice pursuant to paragraph 7.4 shall be settled by final and binding arbitration in accordance with the provisions of this section. The sole issue to be decided in any such arbitration shall be whether any Release Event has occurred. PAGE 3 <PAGE> 8.2 Notice If, within fifteen (15) days after receipt of any notice from Agent that it has received a Dispute Notice, the dispute has not been resolved in a mutually acceptable manner, either party may initiate the arbitration procedure under this section by giving the other party written notice demanding arbitration of the dispute. 8.3 Arbitration Unless otherwise agreed by UPI and AT&T, any dispute submitted to arbitration under this section shall be presented to a panel of three arbitrators. The party demanding arbitration under paragraph 8.2 shall appoint and specify one of the arbitrators in its notice demanding the arbitration. The other party shall appoint a second arbitrator and give the demanding Party written notice of such appointment within thirty (30) days after the notice demanding the arbitration. The two arbitrators so appointed shall appoint a third arbitrator who shall act as chairman of the arbitration panel, if the two arbitrators appointed by the parties do not agree upon the third arbitrator within thirty (30) days after appointment of the second arbitrator, then, upon request of UPI or AT&T, the third arbitrator shall be appointed in accordance with the Arbitration Rules of the Judicial Arbitration and Mediation Services, Inc. (J.A.M.S.). If any arbitrator is unable to serve as an arbitrator, then a substitute arbitrator shall be promptly designated by the person or persons who appointed the arbitrator who is unable to serve. 8.4 No Ex Parte Discussions No party may discuss the dispute to be arbitrated with any arbitrator after such arbitrator is appointed and prior to the arbitration panel's determination, without providing the other party with reasonable advance notice and the opportunity to participate in such discussions. 8.5 Procedures The arbitration shall be conducted in accordance with the Arbitration Rules of J.A.M.S. Additional rules of procedure for the conduct of the arbitration may be determined by a majority of the arbitrators. Such rules of procedures shall direct the expeditious evaluation of the merits of the dispute and rendering of a decision consistent with the complexity of the dispute being arbitrated. In any arbitration, each party shall have: (a) full access to the records of the other parties that pertain to the dispute; (b) the power to call for testimony of any director, officer, employee, agent or representative of the other parties; and (c) all other rights of discovery accorded to parties in civil actions under the Federal Rules of Civil Procedure (or rules or laws applicable to court proceedings adopted in lieu thereof) applicable in proceedings before the court specified in section 9.8. 8.6 Decision Unless otherwise agreed by UPI and AT&T, the arbitrators shall render a decision determining whether the Release Event has occurred within thirty (30) calendar days after completion of the arbitration proceeding. The decision of the arbitration panel shall be made by a majority of the arbitrators and shall be binding upon the parties. PAGE 4 <PAGE> 8.7 Location Any arbitration hearings under this Agreement shall be held at a mutually acceptable location in or near San Francisco, California, U.S.A. 8.8 Jurisdiction The Superior Court of the State of California in and for the City and County of San Francisco, shall be the forum for any court supervision of any arbitration under this section. 8.9 Costs Each party shall pay for the services and expenses of the arbitrator appointed by it. The costs for the services and expenses of the third arbitrator and all administration costs of the arbitration shall be paid by the non- prevailing party. 9. Interpleader Notwithstanding any other provision of this Agreement, if Agent receives a Release Notice and Agent is uncertain whether the Release Notice was timely or otherwise effective, then Agent may, in its sole discretion, begin an interpleader action and deposit the Deposit with the clerk of the court or withhold release of the Deposit until instructed otherwise by court order. In connection with any such deposit, Agent shall seek an appropriate order to seal the deposit so as to prevent release or disclosure to third parties. 10. Fees AT&T shall pay to Agent the initial and annual fees prescribed on the attached Exhibit 1 for performance of services by Agent during the Term. Agent may change its rates from time to time by providing at least sixty (60) days' advance written notice of such change to AT&T. 11. No Duty to Inquire Into Truth, Authenticity or Authority; Right to Require Additional Documents Agent shall not be required to inquire into the truth of any statements or representations contained in any notices, certificates or other documents required or otherwise provided hereunder, and shall be entitled to assume that the signatures on such documents are genuine, that the persons signing on behalf of any party thereto are duly authorized to execute the same, and that all actions necessary to render any such documents binding on the party purportedly executing the same have been duly undertaken. Without in any way limiting the foregoing, Agent may in its discretion require from UPI or AT&T additional documents which it deems to be necessary or desirable in the course of performing its obligations hereunder. 12. Indemnification Agent shall be responsible to perform its obligations under this Agreement and to act in a reasonable and prudent manner with regard to the escrow arrangement set forth herein. Provided Agent has acted in the manner stated in the preceding sentence, AT&T and UPI each agree to indemnify, defend and hold harmless Agent from any and all claims, actions, damages, arbitration fees and expenses, costs, attorney's fees and other liabilities incurred by Agent relating in any way to the escrow arrangement set forth in this Agreement. PAGE 5 <PAGE> 13. Termination 13.1 Termination by Agent Agent may, at any time, terminate the term of this Agreement by resigning as escrow agent hereunder. Agent shall provide UPI and AT&T ninety (90) days' advance written notice of its intention to resign. Further, Agent may terminate the term of this Agreement upon written notice to UPI and AT&T if AT&T defaults in the payment of the fees payable to Agent under section 10 and fails to cure such default within ten (10) days after its receipt of written notice of default from Agent. 13.2 Termination by AT&T AT&T may, at any time, terminate the term of this Agreement by providing Agent fourteen (14) days advance written notice of such termination, signed by an officer of AT&T; provided that all fees payable to Agent for performance of its services hereunder have been fully paid. 13.3 No Other Termination Except as provided in paragraphs 13.1 and 13.2, this Escrow Agreement may not be terminated or modified except in writing signed by Agent, UPI and AT&T; provided, however, that this Agreement will terminate and all items held in escrow hereunder will be returned to UPI upon any termination of the license granted to AT&T under Section 2 of the Software Agreement. 14.
