In any event, critical issues shall be discussed and dealt with as soon as possible after identification by Tumbleweed or UPS. In the event Tumbleweed fails to specify in writing any critical issue with respect to a given period in such manner and at such time as required pursuant to this Section 2(i), it shall be presumed that no critical issue arose during such period. j. EXTENSIONS OF TIME. If Tumbleweed is delayed at any time during Phase I or Phase II of the Project by the failure of UPS or its Affiliates or Associates to perform the obligations set forth in Exhibit D hereto, then upon notice from Tumbleweed to UPS, the affected Implementation Schedule date(s) will be reasonably extended to accommodate such delays, not to exceed a day-for-day extension for each such delay. If Tumbleweed is delayed at any time during Phase I or Phase II of the Project by supervening conditions beyond Tumbleweed's reasonable control, and arising without its fault or negligence after the execution hereof, including acts of God, civil commotion, strikes, labor disputes, or governmental demands or requirements, then upon notice from Tumbleweed to UPS, the affected Implementation Schedule date(s) will be reasonably extended to accommodate such delays, not to exceed a day-for-day extension for each such delay and all such extensions pursuant to this sentence not to exceed, in the aggregate, ten (10) days. If Tumbleweed will be delayed by more than ten (10) days, in the aggregate, during Phase I or Phase II of the Project by supervening conditions beyond Tumbleweed's reasonable control, including acts of God, civil commotion, strikes, labor disputes, or governmental demands or requirements, then Tumbleweed may request that the affected Implementation Schedule date(s) be further extended. UPS shall review such request with Tumbleweed at the appropriate conference call (or meeting) provided for in Section 2(i) above, and shall grant an extension of time commensurate with the circumstances, subject to the following conditions: (A) The cause of the delay (i) is beyond Tumbleweed's control and arises without its fault or negligence, and (ii) arises after the execution hereof; (B) Tumbleweed demonstrates that the affected Implementation Schedule date(s) will be actually and necessarily delayed; and (C) Tumbleweed provides a written request to UPS in conjunction with the next progress report provided for in Section 2(i) above after the time Tumbleweed knows of any cause or circumstances which might, under reasonable foreseeable circumstances, result in a delay. If Tumbleweed shall fail to give the foregoing notice, the right to request an extension for such cause shall be waived. If either party is delayed at any time in the performance of its obligations hereunder subsequent to Phase II of the Project by the failure of the other party to perform its obligations under this Agreement, or by supervening conditions beyond such party's reasonable UPS/Tumbleweed Confidential 10 December 18, 1997 control, including acts of God, civil commotion, strikes, labor disputes, or governmental demands or requirements, then the parties shall review the cause of such delay at the appropriate conference call (or meeting) provided for in Section 2(i) above, and an extension of time commensurate with the circumstances shall be provided, subject to the following conditions: (X) The cause of the delay is beyond the control of the party requesting the extension of time and arises without its fault or negligence; and (Y) The party requesting the extension demonstrates that the affected obligation(s) will be actually and necessarily delayed. Any delay by Tumbleweed in the performance of its obligations hereunder as a result of (i) any failure by UPS, its Affiliates or Associates to perform their express obligations under this Agreement; or (ii) by any supervening condition beyond Tumbleweed's reasonable control, and which failure or condition satisfies the applicable requirement(s) set forth above in this subsection (j) shall be deemed an "Excusable Delay," with respect to Tumbleweed's performance. Unless otherwise agreed by the parties, in the event of an Excusable Delay, Tumbleweed shall proceed continuously and diligently with the performance of the unaffected portions of its obligations under this Agreement. Notwithstanding the foregoing, UPS shall have the right to terminate this Agreement, or any Phase hereunder or Maintenance Services (hereinafter defined), as applicable, without liability to Tumbleweed (except as expressly set forth in this paragraph), in the event that any Excusable Delay materially adversely affects UPS's ability to offer the Messaging Service, whereupon (i) if such Excusable Delay occurs prior to acceptance of Phase II of the Project, (x) if such Excusable Delay is due to UPS's or its Affiliates' or Associates' failure to perform the obligations set forth in Exhibit D hereto, Tumbleweed shall be entitled to payment of the Initial Phase Development Fee described in Section 6(g) in full, but shall refund to UPS any License Fees previously paid pursuant to Section 6(a), in which case all licenses granted hereunder shall terminate, Section 15 terminates, and neither party shall have any further obligations to the other, and (y) if such Excusable Delay is not due to any such failure by UPS. Tumbleweed shall refund to UPS all amounts paid hereunder, in which case all licenses granted hereunder shall terminate, Section 15 terminates, and neither party shall have any further obligations to the other; (ii) in the event that such Excusable Delay occurs in connection with any subsequent Phase of the Project, and if such Excusable Delay is not due to any failure by UPS or its Affiliates or Associates to perform the obligations set forth in the relevant Specifications, Tumbleweed shall refund to UPS all amounts paid with respect to such Phase; and (iii) in the event that such Excusable Delay involves the provision of Maintenance Services by Tumbleweed, Tumbleweed shall refund to UPS a pro rata amount (calculated on a daily basis) of any annual Maintenance Service fees previously paid by UPS for the period in which such termination is effective. Such foregoing termination (and associated refund, if applicable) shall constitute UPS's sole and exclusive remedy for any Excusable Delay which materially adversely affects UPS's ability to offer the Messaging Service.

Neither party makes any guarantee or commitment as to the success of its marketing effort, and each party agrees that the other party has no obligation to it whatsoever other than as specifically provided in this Agreement. f. ADDITIONAL MARKETING AND SALES SUPPORT. For the period ending (1) year after the Commercial Availability Date, in addition to its other marketing and sales support obligations hereunder, Tumbleweed shall provide the Services set forth in Exhibit G hereto. 8. WARRANTIES. Tumbleweed hereby warrants and represents to UPS as follows: a. SOFTWARE. All Software and Documentation delivered pursuant to this Agreement will materially conform to the Detailed Design Specifications therefor. In the event of any breach of the foregoing warranty, Tumbleweed shall use commercially reasonable efforts to promptly correct or replace the Software so that it materially conforms with the Detailed Design Specifications. As the Internet transmission medium and servers connected thereto are not entirely free form unauthorized access, Tumbleweed does not warrant that operation of the Software will be uninterrupted, secure, or error-free, or that all errors will be corrected, and further does not warrant that the information stored or transmitted by the Software will be free from unauthorized modification. The warranty set forth in this Section 8(a) shall remain in effect for the period ending [ * ] following acceptance of Phase II of the Project pursuant to Section 4(b) hereof (the "Warranty Period"), and for the period during which Tumbleweed is providing continuing support for the Software pursuant to Section 9 below (the "Support Period"). The foregoing warranty does not cover non-conformities due to: (a) any modification of the Software performed by any Person other than Tumbleweed or any of its Associates (except for localizations certified by Tumbleweed as set forth in Section 5(f) and except for modifications to the base Software enabled by the Developer Kit Software ); (b) operation of the Software under environmental conditions outside of normal operating ranges for computer hardware for UPS's data center; (c) any use of the Software on a system that does not meet Tumbleweed's minimum standards for such Software, to the extent such minimum standards are included in the Specifications; and (d) hardware or non-Tumbleweed software (where such non-conformity is due solely to the operation of such hardware or non-Tumbleweed software). b. COMPATIBILITY. All Enhancements to the Software furnished hereunder will be implemented in such a manner as to maintain backward compatibility with the immedi- --------------- [*]Confidential treatment has been requested with respect to certain information contained in this document. Confidential portions have been omitted from the public filing and have been filed separately with the Securities and Exchange Commission. UPS/Tumbleweed Confidential 29 December 18, 1997 ately preceding two (2) versions, and all versions of the Software furnished hereunder and/or released within the previous year, and with any and all associated interfaces within the Software to other vendors'; software and hardware, as provided for in Section 5(g) hereof, in Exhibit C hereto, or in the Detailed Design Specifications, so that such previous versions or interfaces shall continue to be operable with the Software as Enhanced, in materially the same manner and with materially equivalent performance as prior to the Enhancement; provided, however, that Tumbleweed shall have satisfied such obligation with respect to the preservation of an interface if it furnishes to UPS, as an alternative to backward compatibility, the software retrofit(s) necessary to preserve the functionality of applications written to such previous interface. As used in this subsection (b), a "version" is any version of the Standard Software designated, in Tumbleweed's sole but reasonable discretion, by a change in the version number to the left of the first decimal point. On a case by case basis, UPS agrees to consider, in good faith, reducing Tumbleweed's two (2) version backward compatibility commitment to one (1) version for a particular version release; provided, however, that no such reduction shall be taken or held to extend to any subsequent version of the Software released by Tumbleweed hereunder. c. SERVICES. The work to be performed hereunder shall be of professional quality and will conform to generally accepted standards for software in the software development and software support fields. d. Intentionally omitted. e. RELIABILITY. During the Warranty Period and subsequent Support Period, when UPS elects to secure the Services of the DSP at the Supported Datacenter(s), in addition to the individual performance standards for the Software set forth in the Detailed Design Specifications, Tumbleweed hereby represents and warrants to UPS that the Software operating at such Supported Datacenter(s) shall on an ongoing basis, operate without unresolved Critical or Major Defects ("Uptime"), measured on a monthly basis, for an average of [ * ]. For the purposes of determining Uptime, the following formula shall be used: Uptime = Unit Hours of Operation minus Downtime (to be expressed -------------------------------------- as a percentage) Unit Hours of Operation For the purposes of this Section 8(e), "Unit Hours of Operation" shall mean twenty-four (24) hours per day, seven (7) days per week and "Downtime" shall mean that period of time when the Messaging Service at the Supported Datacenter(s) is inoperable (unavailable) for reasons --------------- [*]Confidential treatment has been requested with respect to certain information contained in this document. Confidential portions have been omitted from the public filing and have been filed separately with the Securities and Exchange Commission. UPS/Tumbleweed Confidential 30 December 18, 1997 attributable to the Software. Downtime for each incident shall commence from the time UPS has made a BONA FIDE attempt to notify Tumbleweed (or the DSP) that the Messaging Service at the Supported Datacenter(s) is inoperable for reasons attributable to the Software, and shall continue until the Messaging Service at the Supported Datacenter(s) is restored to fully operable condition, but Downtime shall specifically exclude any time (x) required to perform scheduled maintenance upgrades (which shall be scheduled by UPS during non-peak hours for the Messaging Service), or (y) spent as a result of any delay by UPS in providing Tumbleweed or its DSP with access to the hardware and software at the Supported Datacenter(s). UPS will consider, in good faith, any recommendations made by Tumbleweed's DSP(s) with respect to the operation of the Supported Datacenter(s), where such recommendations shall be limited to the requirements of operating a data center for the Software in a professional manner consistent with generally accepted standards for data center operation (including, but not limited to, the operation of redundant "hot" servers for system integrity, multiple data line access, regular backups, and the like). At a minimum, UPS shall implement (i) the operation of redundant "hot" servers, (ii) automatic regular backups, and (iii) automatic switching to redundant servers in the event of a networking or hardware failure (the "Minimum Conditions"). f. Intentionally omitted. g. LOCKS. Except to the extent disclosed in the applicable Specifications, Tumbleweed has not inserted, and will not insert, in the Software any lock, clock, timer, counter, copy protection feature, CPU serial number reference, "Trojan horse," or other device which is intended to (i) disable or erase all or any part of the Software; (ii) prevent UPS or its Affiliates from fully utilizing all or any part of the Software, or prevent UPS's customers for fully utilizing all or any part of the Client Software and/or Custom Client Software; or (iii) require action or intervention by Tumbleweed or any other Person to allow UPS or its Affiliates, or their respective customers, to utilize all or any part of the Software on the type of computer equipment indicated in Exhibits A and B hereto. h. VIRUSES. Tumbleweed has used and will use all commercially reasonable efforts to ensure that each copy of the Software delivered pursuant to this Agreement is free of any computer "viruses." i. MILLENNIUM. Tumbleweed warrants to UPS (and not to any other parties) that Tumbleweed will use commercially reasonable efforts to ensure that the Software will create, store, process, compare, calculate, sequence and output data relating to (and including) dates on or after January 1, 2000, without producing inaccurate results. The foregoing warranty only applies to errors that are specifically attributable to date-specific data; if such errors would be encountered with non-date-specific data, such errors are covered solely by the other warranty and maintenance provisions of this Agreement. While the exclusions applicable to such other warranty and maintenance provisions also apply to this warranty, UPS acknowledges that inaccurate results also could be caused by software and hardware being used with the Software (including without limitation the BIOS or the operating system), and such inaccurate UPS/Tumbleweed Confidential 31 December 18, 1997 results are not covered by the foregoing warranty. Any enhancement required to enable that the Software to comply with this warranty will be considered part of and covered under the maintenance provisions of this Agreement at no additional charge to UPS. j. WARRANTY DISCLAIMER. EXCEPT AS SET FORTH IN THIS AGREEMENT, TUMBLEWEED AND ITS SUPPLIERS DISCLAIM ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. 9. SOFTWARE SUPPORT SERVICES. Tumbleweed shall provide Maintenance Services pursuant to this Section 9 for the period ending as of December 31, 1999, and on a year to year basis thereafter (collectively, the "Support Period"), unless and until terminated by UPS upon at least ninety (90) days' written notice to Tumbleweed prior to the commencement date of the next annul Support Period. Tumbleweed agrees to make the Maintenance Services available to UPS for the term of this Agreement. a. NOTIFICATION OF DEFECTS. Tumbleweed will promptly (i) notify UPS of any defects or malfunctions in the Software or Documentation of which it learns from any source and which it reasonably expects to lead to a Critical Defect or Major Defect, (ii) use commercially reasonable efforts to correct any such defects or malfunctions, and (iii) upon the earliest availability of such corrections, provide UPS with corrected copies of same. b. ENHANCEMENTS. Tumbleweed will promptly provide to UPS, on or before the date on which any such Enhancement is made generally available to any of Tumbleweed's other customers, copies of the Software and Documentation revised to reflect any Enhancements to the Standard Software which are to be made generally available to Tumbleweed's other customers, including, without limitation, modifications to the Software which can increase the speed, efficiency or ease of operation of the Software or add additional functionality or capabilities to or otherwise improve the functions of the Software, and modifications to the Software which support new protocols, new operating systems and/or new releases of the operating systems and other third party software with which the Software is designed to operate or interface. In the event that Tumbleweed develops an Enhancement for which it will owe a royalty based on the distribution of such Enhancement (a "Royalty Enhancement"), Tumbleweed agrees to offer the Royalty Enhancement to UPS on terms [ * ], and UPS agrees to pay such royalty, [ * ] based solely upon UPS's use of the Royalty Enhancement, in the event UPS elects to license such Royalty Enhancement.

Each UPS support interface must complete the training specified in Section 12 hereof, and UPS's end user support personnel shall have completed either the end user support training specified in Section 12 hereof, or subsequent "train the trainer" sessions conducted by UPS regarding end user support. In the event that requests become excessive or overly burdensome as a result of lack of skill or training by the Support Interface(s), or high rate of turnover of such Support Interface(s), UPS and Tumbleweed personnel shall meet to provide solutions to such problem. --------------- [*]Confidential treatment has been requested with respect to certain information contained in this document. Confidential portions have been omitted from the public filing and have been filed separately with the Securities and Exchange Commission. UPS/Tumbleweed Confidential 33 December 18, 1997 d. SUPPORTED DATACENTER SUPPORT. In order to assist UPS in performance of its first level support obligations for the Server Software and Custom Server Software, Tumbleweed shall make available to UPS for a period of [ * ] from the Commercial Availability Date, one Dedicated Support Personnel at each Supported Datacenter(s) as UPS may so elect. Following such [ * ] period, Tumbleweed shall continue to make the DSP(s) available to UPS on a month to month basis unless and until UPS shall have provided at least ninety (90) days' prior written notice to Tumbleweed of the termination of such DSP Services with respect to one (1) or more Supported Datacenters. In the event that UPS elects to discontinue DSP Services with respect to a particular Supported Datacenter, the parties shall meet to mutually agree upon a reasonable adjustment to the Reliability Warranty set forth in Section 8(e) hereof, and the obligations and remedies set forth in Section 9(e)(ii) and (iii) shall no longer apply, but be replaced by the obligations set forth in Section 9(e)(iv) and (v) with respect to any such data center. The DSP(s) shall have as his, her or their first priority the ongoing support and maintenance of the Software at the Supported Datacenter, and shall be physically present at the Supported Datacenter(s) during UPS Business Hours, and on call (i.e., available by pager) outside of UPS's Business Hours. "Business Hours" are 8:00 a.m. to 6:00 p.m., local time, on Business Days. UPS shall provide to the DSP(s) physical access to the server(s) running the Messaging Service at the Supported Datacenter(s), as well as remote access to any other servers running the Messaging Service, in all cases subject to compliance with UPS's reasonable security measures for such access, remote or otherwise. To the extent that UPS declines or fails to implement the Minimum Conditions (as defined above), Tumbleweed shall not be liable for any response time commitments and associated remedies set forth in Sections 9(e)(ii) and (iii). During the first five (5) days following installation of the Software at each Supported Datacenter, the DSP shall be physically present during UPS Business Hours to assist with the implementation of the Messaging Service at such Supported Datacenter. e. REMEDIAL EFFORTS BY TUMBLEWEED. Tumbleweed will respond to and resolve problems with the Software in accordance with the following procedures: i. UPS shall first attempt to identify and rectify the problem in accordance with its first-level support obligations, which may include consulting with the DSP. If such activities are unsuccessful, the DSP (or one of UPS's Support Interfaces, if UPS is not then covered by Tumbleweed's DSP Services pursuant to Section 9(d) above) shall contact Tumbleweed to report such problem. If the problem may be solved via a telephone consultation, Tumbleweed (or its DSP) shall proceed to attempt to effect such resolution. If remote access is required to permit Tumble- --------------- [*]Confidential treatment has been requested with respect to certain information contained in this document. Confidential portions have been omitted from the public filing and have been filed separately with the Securities and Exchange Commission. UPS/Tumbleweed Confidential 34 December 18, 1997 weed to attempt to diagnose the problem, then subject to Tumbleweed's compliance with UPS's security procedures then in effect, UPS shall provide remote access to UPS's servers running the Messaging Service solely for the purpose of enabling Tumbleweed to attempt to diagnose and remedy reported problems remotely. Based on such remote diagnosis, the parties shall confer to determine whether the Software or some other component is responsible for any problems with respect to the Messaging Service. In the event that the problem does not arise at a Supported Datacenter, and Tumbleweed informs UPS that the Software is not responsible for the problem, and UPS nevertheless reasonably believes that the Software is responsible for such problem and that such problem is a Critical or Major Defect, and after all possible diagnosis by Tumbleweed and discussion by the parties UPS insists that on-site support is the only reasonable solution, Tumbleweed support personnel shall promptly travel to the other UPS datacenter to attempt to effectuate such repairs. In the event that after such travel it becomes clear that the Software was not responsible for such problems and Tumbleweed had informed UPS of such diagnosis prior to such travel, as provided for above, UPS shall reimburse Tumbleweed for all actual expenses incurred in the course of such service call as well as time and materials charges related to the same. In the event that such on-site service had been necessitated by a Critical or Major defect caused by the Software, Tumbleweed shall bear all expenses associated with such on-site call, but no time and materials charges shall be payable in connection therewith. Nothing provided for in this subsection (e)(i) shall have any effect on the remedies available to UPS pursuant to subsections (e)(ii) and (e)(iii) below, provided, however that Tumbleweed's obligations and UPS's remedies set forth in subsections (e)(ii) and (e)(iii) below shall apply only to Supported Datacenters; ii. For a Supported Datacenter, with respect to Critical Defects, as reasonably determined by UPS, Tumbleweed will respond to UPS's request for service by telephone response by a qualified and knowledgeable representative within one (1) hour from the time Tumbleweed receives UPS's call and will complete such repairs expeditiously. Tumbleweed personnel shall render continuous effort with respect to such problems. If Tumbleweed does not respond and remedy such problem in the Software within four (4) hours of receipt of the call , UPS shall be entitled to a credit against future amounts due hereunder of [ * ] the average hourly revenues generated by the Messaging Service (measured over the prior three-month period) for every hour or part thereof after four (4) hours that Tumbleweed fails to remedy such problem. Monies becoming due UPS shall be applied as a credit against any amounts subsequently due from UPS to Tumbleweed. Notwithstanding the foregoing, in the event that Tumbleweed fails to remedy any such problem within fifteen (15) days of receipt of the call, or in the --------------- [*]Confidential treatment has been requested with respect to certain information contained in this document.

For a Supported Datacenter, with respect to Major Defects, as reasonably determined by UPS, Tumbleweed will respond to UPS's request for service by telephone response by a qualified and knowledgeable representative within two (2) hours from the time Tumbleweed receives UPS's call and will complete such repairs expeditiously. Tumbleweed personnel shall render continuous effort with respect to such problems. If Tumbleweed does not respond and remedy such problem in the Software within twenty-four (24) hours of receipt of the call, UPS shall be entitled to a credit against future amounts due hereunder of [ * ] the average hourly revenues generated by the Messaging Service (measured over the prior three-month period) for every hour or part thereof after twenty-four (24) hours that Tumbleweed fails to remedy such problem. Monies becoming due UPS shall be applied as a credit against any amounts subsequently due from UPS to Tumbleweed. Notwithstanding the foregoing, in the event that Tumbleweed fails to remedy any such problem within thirty (30) days of receipt of the call, or in the event that any such problem occurs six (6) or more times within any six (6) month period, such failure shall be deemed to be a material breach by Tumbleweed of this Agreement, in which event the foregoing credits shall no longer accrue and UPS shall be entitled to pursue such damages and remedies as UPS might have pursuant to this Agreement, at law or in equity, subject to the limitations (including the limitations on liability) set forth herein; iv. For locations other than Supported Datacenters, with respect to Critical Defects, as reasonably determined by UPS, Tumbleweed will respond to UPS's request for service by telephone response by a qualified and knowledgeable representative within one (1) hour from the time Tumbleweed receives UPS's call and will complete such repairs within eight (8) hours. Tumbleweed personnel shall render continuous effort with respect to such problems; v. For locations other than Supported Datacenters, with respect to Major Defects, as reasonable determined by UPS, Tumbleweed will respond to UPS's request for service by telephone response by a qualified and knowledgeable representative within two (2) hours from the time Tumbleweed receives UPS's call and will complete such repairs within forty-eight (48) hours. Tumbleweed personnel shall render continuous effort with respect to such problems; and --------------- [*]Confidential treatment has been requested with respect to certain information contained in this document.

With respect to any other problem involving the Software (i.e., Minor Defects), Tumbleweed will respond during Business Hours (hereinafter defined) to UPS's request for service by telephone response by a qualified and knowledgeable representative within four (4) hours from the time Tumbleweed receives UPS's call and will use commercially reasonable efforts to correct such Minor Defect(s) in the next Enhancement of the applicable Software. f. TERMINATION OF MAINTENANCE. UPS shall have the right to terminate the maintenance provisions of this Agreement, without affecting its Licenses to the Software granted under Section 5 hereof, at any time in the event of a breach by Tumbleweed of any of its maintenance obligations hereunder if Tumbleweed shall fail to cure such breach within thirty (30) calendar days of receipt of written notice thereof. Except as expressly provided for in Section 9(e) above, any termination of the maintenance provisions of this Agreement by UPS shall be in addition to any and all other legal or equitable remedies which may be available to UPS. In the event that UPS has terminated the maintenance provisions of this Agreement, and subsequently desires maintenance services, Tumbleweed shall have the right to require that UPS first pay all maintenance fees which would have been otherwise due during the interim and upgrade the Software to the currently supported versions of the Software. g. MAINTENANCE EXCLUSIONS. Tumbleweed will only provide Maintenance Services for (x) the then-current version of the Software, (y) the immediately preceding two (2) versions of the Software, and (z) all preceding versions of the Software (in addition to the immediately preceding version) for a period of [ * ] following the release of such preceding version(s). As used in this subsection (h), a "version" is any version of the Standard Software designated, in Tumbleweed's sole but reasonable discretion, by a change in the version number to the left of the first decimal point. Furthermore, Maintenance Services do not include any service required as a result of: (a) any modification of the Software performed by any Person other than Tumbleweed or any of its Associates (except for localizations certified by Tumbleweed as set forth in Section 5(f) and except for modifications to the base Software enabled by the Developer Kit Software); (b) operation of the Software under environmental conditions outside of normal operating ranges for computer hardware for UPS's data centers; (c) any use of the Software on a system that does not meet Tumbleweed's minimum standards for such Software, to the extent such minimum standards are included in the Specifications; or (d) the operation of hardware or non-Tumbleweed software (where such non-conformity is due solely to the operation of such hardware or non-Tumbleweed software). In the event that Tumbleweed provides services that are shown to be due to a factor not covered by the Maintenance Services enumerated in this Agreement, UPS shall pay Tumbleweed's then-current time --------------- [*]Confidential treatment has been requested with respect to certain information contained in this document. Confidential portions have been omitted from the public filing and have been filed separately with the Securities and Exchange Commission.

Except as set forth herein, Tumbleweed shall be responsible for all charges incurred in establishing and maintaining such escrow account. UPS shall be entitled to receive a copy of such Source Code under the circumstances set forth in Section 11(a) above and pursuant to the procedures set forth in the Escrow Agreement. If Tumbleweed corrects any defects in, or provides any revision to, the Software under Section 9 hereof, or under any software maintenance agreement between the parties, Tumbleweed shall simultaneously furnish the escrow agent with a corrected or revised copy of the Source Code for the Software. c. VERIFICATION OF ESCROW DEPOSIT(S). UPS may periodically, but not more frequently than once per year, trigger fresh escrow deposits. UPS shall reimburse Tumbleweed and the escrow agent under the Escrow Agreement for the reasonable expenses incurred in the preparation of such fresh escrow deposits. In addition to triggering fresh deposits, UPS shall have the right, either itself or through a third party designated by UPS, to validate the materials on deposit upon thirty (30) calendar days prior written notice to and in the presence of Tumbleweed, but no more frequently than two (2) times per year. Any third party designated by UPS to validate the materials on deposit shall be required to execute a nondisclosure agreement with Tumbleweed, in a form reasonably satisfactory to Tumbleweed, which nondisclosure agreement shall require that such third party's report to UPS contain only a non-confidential description of results of such validation. Verification shall take place at Tumbleweed's convenience during normal business hours on mutually-designated hardware. Such verification shall be at UPS's expense unless the materials on deposit have not been deposited at the frequency required in Section 11(b) above, in which event Tumbleweed shall bear all costs associated therewith. d. OWNERSHIP OF MODIFICATIONS MADE BY UPS. Any and all Derivative Works to the Source code released from escrow which are made by or on behalf of UPS shall be the sole property of UPS. UPS acknowledges that its ownership of such Derivative Works in no way, form or manner creates or transfers any right or title in the Source code to the underlying Standard Software, and that its ownership rights are limited solely to the Derivative Works. e. SOURCE CODE LICENSE. Upon the occurrence of the release events set forth in Section 11(a), Tumbleweed hereby automatically grants to UPS, a non-exclusive, irrevocable license to Use, reproduce, modify, maintain, support, update, make, have made, and create Derivative Works of the Source code, and to create object code copies of such software thereby created solely to support and enhance the Messaging Service. UPS shall have the right to employ third party contractors to exercise the foregoing license, so long as such third parties are bound by terms no less protective of the Source Code than the terms of this Agreement, including an obligation to protect the confidential and proprietary nature of the Source Code and to use the Source Code only on UPS's behalf and only to the extent necessary to support the foregoing license. Except as incident to the foregoing grant, UPS may not use, reproduce, distribute, create Derivative Works of, publicly perform, publicly display, digitally perform, UPS/Tumbleweed Confidential 40 December 18, 1997 make, have made, sell, offer to sell or import the Source Code. UPS shall continue to pay Royalties, and UPS's failure to make such payments when due shall terminate this source code license. f. DISCONTINUANCE OF MARKETING. If Tumbleweed ceases to market the Standard Software and such marketing is not continued by another Person, or is continued by another Person which UPS for reasonable cause deems unsatisfactory, at UPS's request, UPS and Tumbleweed will enter into good faith negotiations to license the Source code to UPS on commercially reasonable terms. 12. TRAINING SERVICES. In addition to the training outlined in Exhibit G hereto, the License Fees and development fees specified in Section 6 hereof include all costs (other than Tumbleweed's reasonable and actual travel and living expenses) for the following training programs: (i) attendance of up to ten (10) of UPS's technical support personnel at Tumbleweed's two-day system administrator training course, for which course UPS shall have the right to select the topics to be covered based upon training materials supplied to UPS by Tumbleweed in advance of such training; and (ii) training of up to fifteen (15) of UPS's end user support personnel on the Use and operation of the Software. Pursuant to a mutually agreed upon schedule, Tumbleweed shall provide sufficient experienced and qualified personnel to conduct such training at the location(s) designated by UPS. The parties may mutually agree that Tumbleweed shall perform additional training for UPS. Such training may be purchased by UPS, in it sole discretion, at Tumbleweed's standard list price and shall be conducted at a mutually agreed upon time. In addition, if the paries agree that such training shall be performed at any site other than Tumbleweed's Redwood City facility, UPS shall pay all reasonable and actual travel and living expenses incurred by Tumbleweed in performing the training. 13. COMPLIANCE WITH LAWS. a. LICENSES AND PERMITS. Tumbleweed (i) is responsible for obtaining all licenses, authorizations and permits required by applicable legislative enactments and regulatory authorizations, whether United States federal, state, local or otherwise, which are required in connection with the export of the Software from the United States to foreign countries which may reasonably be considered to be "major" markets, and/or in connection with the exercise by UPS and its sublicensees (to the extent of their sublicenses), within the United States, of their respective rights derived from this Agreement; and (ii) has financial responsibility for, and shall pay, all fees and taxes associated with such licenses, authorizations and permits.

Notwithstanding the foregoing, upon UPS's reasonable request and subject to UPS's agreement to reimburse any associated costs and reasonable expenses, Tumbleweed will promptly execute all documents and do all acts which may be necessary, desirable or convenient to enable UPS at its expense to obtain such licenses, authorizations and permits. In the event that Tumbleweed has expertise in procuring any such licenses, authorizations or permits, Tumbleweed shall cooperate with UPS to share such information regarding the same. b. CHANGES IN LAW AND REGULATIONS. Tumbleweed shall use reasonable efforts to identify the impact of changes in applicable legislative enactments and regulations on the functions performed by the Software, whether such enactments or regulations are foreign or Untied States federal, state, local or otherwise. Tumbleweed shall notify UPS of such changes and shall work with UPS to identify the impact of such changes on UPS's offering of the Messaging Service. Tumbleweed shall promptly make any resulting modifications to the Software as reasonable necessary as a result of such changes, and shall be responsible for, and shall pay for, the cost of any such changes directly related to Tumbleweed's business. 14. INDEMNIFICATION. a. PROPRIETARY RIGHTS INDEMNIFICATION. Tumbleweed shall indemnify, defend and hold UPS and its Affiliates and Server Sublicensees and their respective officers, directors, agents and employees harmless from and against any and all liabilities, damages, losses, expenses, claims, demands, suits, fines or judgments, including reasonable attorneys' fees, and costs and expenses incidental thereto, which may be suffered by, accrued against, charged to or recoverable from UPS or any of its Affiliates or Server Sublicensees, or their respective officers, directors, agents or employees, arising out of a claim that the Software or Documentation, or any portion thereof, infringes or misappropriates any United States or foreign patent, copyright, trade secret or other proprietary right.

Tumbleweed will not be liable for claims based upon: (w) compliance with UPS specifications, where such specifications would necessarily give rise to infringement (i.e. where alternate implementations of substantially the same functionality would not avoid such infringement); (x) the use or combination of the Software with software, hardware, or other materials not provided or approved by Tumbleweed; (y) any use of a version of the Software which has been altered or modified other than by Tumbleweed or an authorized representative of Tumbleweed, if infringement would not have occurred but for the alteration or modification; or (z) any UPS Intellectual Property incorporated into the Custom Software.
