Within ten (10) Business Days of the delivery of the<br \/>\nDetailed Design Specifications to UPS, UPS shall notify Tumbleweed in writing of<br \/>\nits acceptance or rejection of the Detailed Design Specifications.  If the<br \/>\nDetailed Design Specifications are rejected, UPS will specify the reasons for<br \/>\nsuch rejection and Tumbleweed shall have ten (10) Business Days to revise and<br \/>\nre-deliver amended Detailed Design Specifications to UPS for acceptance.  Once<br \/>\naccepted by UPS, the Detailed Design Specifications shall supersede the<br \/>\nFunctional Specifications for that portion of the Project to which the Detailed<br \/>\nDesign Specifications relate.  If UPS rejects the amended Detailed Design<br \/>\nSpecifications, UPS&#8217;s sole and exclusive remedy shall be to terminate the<br \/>\nparticular phase to which UPS&#8217;s rejection relates.<\/p>\n<p>          e.   ACCEPTANCE OF SPECIFICATIONS.  Upon acceptance of the<br \/>\nSpecifications for any Phase of the Project such Specifications shall be deemed<br \/>\nto be a part of this Agreement, and Tumbleweed shall perform the Services<br \/>\ndescribed in such Specifications within the time frames, in the manner, and for<br \/>\nthe fees specified therein.<\/p>\n<p>          f.   PROGRAMMING AND TUMBLEWEED TESTING.  After approval of the<br \/>\nDetailed Design Specifications by UPS pursuant o Section 2(d) hereof, Tumbleweed<br \/>\nshall commence program coding and testing to provide the necessary programming<br \/>\nof the Software.  Upon completion of the program coding and testing, Tumbleweed<br \/>\nshall notify UPS in writing that such program coding and testing is completed<br \/>\nand that, upon delivery of the Software to UPS (and installation thereof by<br \/>\nTumbleweed in the event such installation is at a Supported Datacenter) UPS may<br \/>\ncommence its acceptance testing.<\/p>\n<p>          g.   ON-SITE INSTALLATION SUPPORT.  Upon delivery of the Phase II<br \/>\nSoftware, and again upon completion of the upgrade of the Custom Software to<br \/>\nreflect version 2.0 of the Standard Software, Tumbleweed shall identify and<br \/>\nassign at least one (1) Tumbleweed professional services employee to be on site<br \/>\nat UPS&#8217;s facilities and devote all of his or her business time for a period of<br \/>\nup to three (3) Business Days, the duration of which will be determined by<\/p>\n<p>UPS\/Tumbleweed Confidential             8                      December 18, 1997<\/p>\n<p>UPS in its sole discretion, to support the installation of the Software.  In the<br \/>\nevent that UPS requires additional support beyond such three (3) Business Day<br \/>\nperiod, and such support is not required as a result of any problems with the<br \/>\nSoftware encountered during such installation, UPS shall pay Tumbleweed for such<br \/>\nadditional on-site installation support Services on a time and materials basis.<\/p>\n<p>          h.   DESIGNATION OF PROJECT COORDINATORS.  Tumbleweed shall designate<br \/>\nRobert A. Krauss as its Project coordinator (the &#8220;Tumbleweed Project<br \/>\nCoordinator&#8221;), who shall be assigned by Tumbleweed to supervise the Project,<br \/>\nshall devote the necessary time to such endeavor, and shall serve as UPS&#8217;s point<br \/>\nof contact for the resolution of problems.  The services of the Tumbleweed<br \/>\nProject Coordinator shall be included in the fees provided for herein.  UPS<br \/>\nshall also designate an employee who shall be assigned by UPS to coordinate<br \/>\nUPS&#8217;s involvement in the Project (the &#8220;UPS Project Coordinator&#8221;), who shall<br \/>\nserve as Tumbleweed&#8217;s point of contact for the resolution of problems.  The<br \/>\ninitial UPS Project Coordinator is Jack Carrig.  Either party may change its<br \/>\nProject Coordinator from time to time upon prior written notice to the other<br \/>\nparty; provided, however, that Tumbleweed shall not change the Tumbleweed<br \/>\nProject Coordinator with respect to any Phase of the Project without the prior<br \/>\nwritten consent of UPS, which consent shall not be unreasonably withheld, unless<br \/>\nsuch individual shall have left the employment of Tumbleweed.<\/p>\n<p>          i.   PROGRESS REPORTS.  The UPS Project Coordinator and Tumbleweed<br \/>\nProject Coordinator, as well as appropriate additional personnel involved in the<br \/>\nparticular task underway, shall arrange a conference call (or schedule a meeting<br \/>\nat a mutually agreed site) to discuss the progress made by Tumbleweed and UPS.<br \/>\nSuch call or meeting shall take place (i) each week during the period prior to<br \/>\nthe Commercial Availability Date, (ii) each month for the first year of the<br \/>\nAgreement, and (iii) each quarter for the remainder of the Agreement.  Each such<br \/>\nconference call (or meeting) shall include a discussion by the parties of any<br \/>\nactual or potential events which may give rise to delays in any schedules.  In<br \/>\norder to facilitate proper project management, UPS shall notify Tumbleweed<br \/>\npromptly of any actual or potential events which may give rise to delays of any<br \/>\nUPS deliverables or performance of UPS&#8217;s obligations (or any obligations of<br \/>\nUPS&#8217;s Affiliates or Associates) under this Agreement, and Tumbleweed shall, for<br \/>\neach such conference call (or meeting), provide UPS with a progress report<br \/>\nspecifying in detail:<\/p>\n<p>     (A)  Any critical issue encountered by Tumbleweed during the preceding<br \/>\n          period, including without limitation, the failure of either party to<br \/>\n          perform, any delay of either party in performing or the inadequate<br \/>\n          performance of either party, which may prevent or tend to prevent<br \/>\n          Tumbleweed from completing any task by the completion date;<\/p>\n<p>     (B)  An estimated length of any delay which may result from any critical<br \/>\n          issues; and<\/p>\n<p>     (C)  The cause of any critical issue and the specific steps taken or<br \/>\n          proposed to be taken by Tumbleweed or UPS, as appropriate, to remedy<br \/>\n          such critical issue.<\/p>\n<p>UPS\/Tumbleweed Confidential             9                      December 18, 1997<\/p>\n<p>          Each progress report provided by Tumbleweed pursuant to this Section<br \/>\n2(i) shall include recent critical issues discussed and dealt with, together<br \/>\nwith those not yet raised by Tumbleweed, during the preceding period.  In any<br \/>\nevent, critical issues shall be discussed and dealt with as soon as possible<br \/>\nafter identification by Tumbleweed or UPS.  In the event Tumbleweed fails to<br \/>\nspecify in writing any critical issue with respect to a given period in such<br \/>\nmanner and at such time as required pursuant to this Section 2(i), it shall be<br \/>\npresumed that no critical issue arose during such period.<\/p>\n<p>          j.   EXTENSIONS OF TIME.  If Tumbleweed is delayed at any time during<br \/>\nPhase I or Phase II of the Project by the failure of UPS or its Affiliates or<br \/>\nAssociates to perform the obligations set forth in Exhibit D hereto, then upon<br \/>\nnotice from Tumbleweed to UPS, the affected Implementation Schedule date(s) will<br \/>\nbe reasonably extended to accommodate such delays, not to exceed a day-for-day<br \/>\nextension for each such delay.  If Tumbleweed is delayed at any time during<br \/>\nPhase I or Phase II of the Project by supervening conditions beyond Tumbleweed&#8217;s<br \/>\nreasonable control, and arising without its fault or negligence after the<br \/>\nexecution hereof, including acts of God, civil commotion, strikes, labor<br \/>\ndisputes, or governmental demands or requirements, then upon notice from<br \/>\nTumbleweed to UPS, the affected Implementation Schedule date(s) will be<br \/>\nreasonably extended to accommodate such delays, not to exceed a day-for-day<br \/>\nextension for each such delay and all such extensions pursuant to this sentence<br \/>\nnot to exceed, in the aggregate, ten (10) days.  If Tumbleweed will be delayed<br \/>\nby more than ten (10) days, in the aggregate, during Phase I or Phase II of the<br \/>\nProject by supervening conditions beyond Tumbleweed&#8217;s reasonable control,<br \/>\nincluding acts of God, civil commotion, strikes, labor disputes, or governmental<br \/>\ndemands or requirements, then Tumbleweed may request that the affected<br \/>\nImplementation Schedule date(s) be further extended.  UPS shall review such<br \/>\nrequest with Tumbleweed at the appropriate conference call (or meeting) provided<br \/>\nfor in Section 2(i) above, and shall grant an extension of time commensurate<br \/>\nwith the circumstances, subject to the following conditions:<\/p>\n<p>     (A)  The cause of the delay (i) is beyond Tumbleweed&#8217;s control and arises<br \/>\n          without its fault or negligence, and (ii) arises after the execution<br \/>\n          hereof;<\/p>\n<p>     (B)  Tumbleweed demonstrates that the affected Implementation Schedule<br \/>\n          date(s) will be actually and necessarily delayed; and<\/p>\n<p>     (C)  Tumbleweed provides a written request to UPS in conjunction with the<br \/>\n          next progress report provided for in Section 2(i) above after the time<br \/>\n          Tumbleweed knows of any cause or circumstances which might, under<br \/>\n          reasonable foreseeable circumstances, result in a delay.  If<br \/>\n          Tumbleweed shall fail to give the foregoing notice, the right to<br \/>\n          request an extension for such cause shall be waived.<\/p>\n<p>          If either party is delayed at any time in the performance of its<br \/>\nobligations hereunder subsequent to Phase II of the Project by the failure of<br \/>\nthe other party to perform its obligations under this Agreement, or by<br \/>\nsupervening conditions beyond such party&#8217;s reasonable<\/p>\n<p>UPS\/Tumbleweed Confidential            10                      December 18, 1997<\/p>\n<p>control, including acts of God, civil commotion, strikes, labor disputes, or<br \/>\ngovernmental demands or requirements, then the parties shall review the cause of<br \/>\nsuch delay at the appropriate conference call (or meeting) provided for in<br \/>\nSection 2(i) above, and an extension of time commensurate with the circumstances<br \/>\nshall be provided, subject to the following conditions:<\/p>\n<p>     (X)  The cause of the delay is beyond the control of the party requesting<br \/>\n          the extension of time and arises without its fault or negligence; and<\/p>\n<p>     (Y)  The party requesting the extension demonstrates that the affected<br \/>\n          obligation(s) will be actually and necessarily delayed.<\/p>\n<p>          Any delay by Tumbleweed in the performance of its obligations<br \/>\nhereunder as a result of (i) any failure by UPS, its Affiliates or Associates to<br \/>\nperform their express obligations under this Agreement; or (ii) by any<br \/>\nsupervening condition beyond Tumbleweed&#8217;s reasonable control, and which failure<br \/>\nor condition satisfies the applicable requirement(s) set forth above in this<br \/>\nsubsection (j) shall be deemed an &#8220;Excusable Delay,&#8221; with respect to<br \/>\nTumbleweed&#8217;s performance.  Unless otherwise agreed by the parties, in the event<br \/>\nof an Excusable Delay, Tumbleweed shall proceed continuously and diligently with<br \/>\nthe performance of the unaffected portions of its obligations under this<br \/>\nAgreement.<\/p>\n<p>          Notwithstanding the foregoing, UPS shall have the right to terminate<br \/>\nthis Agreement, or any Phase hereunder or Maintenance Services (hereinafter<br \/>\ndefined), as applicable, without liability to Tumbleweed (except as expressly<br \/>\nset forth in this paragraph), in the event that any Excusable Delay materially<br \/>\nadversely affects UPS&#8217;s ability to offer the Messaging Service, whereupon (i) if<br \/>\nsuch Excusable Delay occurs prior to acceptance of Phase II of the Project, (x)<br \/>\nif such Excusable Delay is due to UPS&#8217;s or its Affiliates&#8217; or Associates&#8217;<br \/>\nfailure to perform the obligations set forth in Exhibit D hereto, Tumbleweed<br \/>\nshall be entitled to payment of the Initial Phase Development Fee described in<br \/>\nSection 6(g) in full, but shall refund to UPS any License Fees previously paid<br \/>\npursuant to Section 6(a), in which case all licenses granted hereunder shall<br \/>\nterminate, Section 15 terminates, and neither party shall have any further<br \/>\nobligations to the other, and (y) if such Excusable Delay is not due to any such<br \/>\nfailure by UPS.  Tumbleweed shall refund to UPS all amounts paid hereunder, in<br \/>\nwhich case all licenses granted hereunder shall terminate, Section 15<br \/>\nterminates, and neither party shall have any further obligations to the other;<br \/>\n(ii) in the event that such Excusable Delay occurs in connection with any<br \/>\nsubsequent Phase of the Project, and if such Excusable Delay is not due to any<br \/>\nfailure by UPS or its Affiliates or Associates to perform the obligations set<br \/>\nforth in the relevant Specifications, Tumbleweed shall refund to UPS all amounts<br \/>\npaid with respect to such Phase; and (iii) in the event that such Excusable<br \/>\nDelay involves the provision of Maintenance Services by Tumbleweed, Tumbleweed<br \/>\nshall refund to UPS a pro rata amount (calculated on a daily basis) of any<br \/>\nannual Maintenance Service fees previously paid by UPS for the period in which<br \/>\nsuch termination is effective.  Such foregoing termination (and associated<br \/>\nrefund, if applicable) shall constitute UPS&#8217;s sole and exclusive remedy for any<br \/>\nExcusable Delay which materially adversely affects UPS&#8217;s ability to offer the<br \/>\nMessaging Service.<\/p>\n<p>UPS\/Tumbleweed Confidential            11                      December 18, 1997<\/p>\n<p>          k.   TERMINATION OF DEVELOPMENT SERVICES.  UPS may terminate the<br \/>\nsoftware development Services of Tumbleweed for any reason whatsoever during any<br \/>\nPhase beyond Phase II of this Agreement by not less than [    *     ] written<br \/>\nnotice to Tumbleweed specifying the date upon which termination becomes<br \/>\neffective.  In the event of any termination during any such Phase, Tumbleweed<br \/>\nshall be entitled to payment, on a time and materials basis, for Services<br \/>\nrendered by Tumbleweed prior to the effective date of termination; provided,<br \/>\nhowever, that payments for such Phase shall not exceed the maximum amount<br \/>\nspecified in the applicable Specifications, and such payments shall constitute<br \/>\nfull settlement of any and all claims of Tumbleweed of every description arising<br \/>\nout of or relating to the termination of such Phase, including without<br \/>\nlimitation, claims for lost profits.<\/p>\n<p>     3.   MODIFICATIONS TO SPECIFICATIONS.<\/p>\n<p>          a.   PROCEDURES.  No changes in or deviations from the  Specifications<br \/>\nshall be permitted unless the UPS Project Coordinator shall submit a written<br \/>\nrequest to Tumbleweed setting forth with reasonable specificity any requested<br \/>\nchanges to such Specifications.  Alternatively, a proposal for such a change or<br \/>\ndeviation submitted in writing by Tumbleweed and accepted in writing by UPS<br \/>\nshall suffice for this purpose.  As soon as reasonably practicable, but in no<br \/>\nevent later than ten (10) days following Tumbleweed&#8217;s receipt of such request<br \/>\n(unless a longer period is reasonably required), Tumbleweed shall provide UPS<br \/>\nwith written notice stating any anticipated change in price, schedule, or any<br \/>\nother terms of the Specifications resulting from the requested changes.  All<br \/>\nchanges and adjustments required by Tumbleweed in its notice shall be made by<br \/>\nTumbleweed in good faith.<\/p>\n<p>          b.   ACCEPTED CHANGES.  Unless UPS accepts in writing any changes in<br \/>\nprice, schedule, or other terms set forth by Tumbleweed in its notice, the<br \/>\nchanges to the Specifications shall not be made.  If such changes are accepted<br \/>\nin writing by UPS, the changes to the Specifications shall be made, and UPS&#8217;s<br \/>\nwritten request for such changes and Tumbleweed&#8217;s written acceptance thereof<br \/>\nshall be deemed to constitute an amendment to the Specifications and shall be<br \/>\ndeemed to be a part of this Agreement.<\/p>\n<p>     4.   IMPLEMENTATION AND ACCEPTANCE.<\/p>\n<p>          a.   IMPLEMENTATION SCHEDULE.  The Implementation Schedule attached<br \/>\nhereto as Exhibit D sets forth the timing requirements for the various stages of<br \/>\nthe completion of Phase I and Phase II of the Project.  In the event any<br \/>\nmilestone set forth in the Implementation Schedule is not met due to any delay<br \/>\ncaused by Tumbleweed, in addition to damages for the delay (if applicable), as<br \/>\nprovided for in Section 4(b) below, Tumbleweed shall [     *     ].<\/p>\n<p>&#8212;&#8212;&#8212;&#8212;&#8212;<\/p>\n<p>        [*]Confidential treatment has been requested with respect to certain<br \/>\n     information contained in this document.

ACCEPTANCE TESTING.  Tumbleweed shall notify UPS in writing when<br \/>\nTumbleweed has completed the final version of the Software associated with any<br \/>\nPhase of the Project such that it is ready for acceptance testing by UPS.  UPS<br \/>\nshall then  promptly conduct the acceptance tests provided for in the Detailed<br \/>\nDesign Specifications (the &#8220;Acceptance Tests&#8221;) to determine whether or not the<br \/>\nSoftware, Documentation and other deliverables to be provided pursuant to such<br \/>\nPhase materially conform to the Detailed Design Specifications (the &#8220;Acceptance<br \/>\nStandard&#8221;).  The Acceptance Tests shall be conducted over a period not to exceed<br \/>\nthirty-five (35) days (the &#8220;Acceptance Test Period&#8221;), and may consist both of<br \/>\ntesting by UPS in a test environment and beta testing by allowing a limited<br \/>\nnumber of customers to process Transactions using the Software in a product<br \/>\nenvironment.  In the event that the applicable Software, Documentation and other<br \/>\ndeliverables materially conform to the Acceptance Standard, UPS shall notify<br \/>\nTumbleweed in writing that same have passed the Acceptance Tests.  In the event<br \/>\nthat UPS does not provide notice of rejection of any Phase of the Project by the<br \/>\nend of the Acceptance Test Period for such Phase, such Phase shall be deemed<br \/>\naccepted.<\/p>\n<p>          In the event that the Acceptance Tests reveal that the applicable<br \/>\nSoftware, Documentation and other deliverables, or any portion thereof, to be<br \/>\nprovided pursuant to any Phase do not materially conform to the Acceptance<br \/>\nStandard, then UPS shall so notify Tumbleweed in writing specifying the nature<br \/>\nof such failure, and Tumbleweed shall have [    *     ] to correct such failure<br \/>\nafter which UPS shall have [     *     ] to repeat the Acceptance Tests<br \/>\naccording to the above process; provided, however that UPS will use reasonable<br \/>\nefforts to notify Tumbleweed as promptly as possible during the initial<br \/>\nAcceptance Test Period when and as such failures are identified.  If the<br \/>\nSoftware, Documentation and other deliverables again fail to pass the Acceptance<br \/>\nTests, UPS&#8217;s sole and exclusive remedy shall be to elect one of the following<br \/>\noptions in its sole discretion:  (i) the parties may mutually agree that<br \/>\nTumbleweed shall have an additional [    *     ] to correct the failure, in<br \/>\nwhich case the above process (including, without limitation, these remedies)<br \/>\nshall be repeated; (ii) UPS may accept the applicable Software, Documentation<br \/>\nand other deliverables despite the nonconformities; (iii) the Acceptance Tests<br \/>\nassociated with either Phase I or Phase II of this Agreement, UPS may terminate<br \/>\nthe Agreement, whereupon UPS, at its sole option, may elect one (1) of the<br \/>\nfollowing remedies:  (X) Tumbleweed will [    *      ] which amount is agreed by<br \/>\nthe parties to be the deemed<\/p>\n<p>&#8212;&#8212;&#8212;&#8212;&#8212;<\/p>\n<p>        [*]Confidential treatment has been requested with respect to certain<br \/>\n     information contained in this document.

Further, Tumbleweed<br \/>\nhereby represents and warrants to UPS that version 2.0 of the Standard<br \/>\nSoftware, and the modified version of the Custom Software provided pursuant<br \/>\nto the previous sentence, shall have equivalent or greater functionality and<br \/>\nperformance as version 1.0 of the Standard Software, and Custom Software<br \/>\nassociated therewith, when operated on (A) SUN Ultra servers, with (B) the<br \/>\nSUN Solaris 2.6 operating system or above, with (C) Oracle 7.3 database (with<br \/>\npatch) or above, with (D) Netscape Enterprise Service 3.0C or above (backward<br \/>\ncompatible to 2.01), and must support (E) NFS, and must support (F) separate<br \/>\nHTTP components (multiple web servers talking to the same file, system and<br \/>\ndatabase), and must provide (G) same custom API services as Tumbleweed built<br \/>\nfor UPS in version 1.0 (the functions do not have to be the same, but<br \/>\nfunctionality must be), and (H) Tumbleweed must provide expert assistance for<br \/>\ndeveloping a distributed implementation using multiple HTTP components, and<br \/>\n(I) Tumbleweed must provide expert assistance for developing a redundant data<br \/>\ncenter recovery solution (the solution must be approved by the UPS<br \/>\narchitecture group).  With respect to subsequent Enhancements to the Standard<br \/>\nSoftware, subject to Section 8(b) above, UPS acknowledges that any work that<br \/>\nthe parties mutually agree that Tumbleweed shall perform to conform the<br \/>\nCustom Software to any such subsequent Enhancement shall be performed as part<br \/>\nof a new Phase pursuant to Section 2 hereof.  With respect to all<br \/>\nEnhancements, Tumbleweed shall provide procedures, such as database<br \/>\nconversion procedures where applicable, and any computer program(s) required<br \/>\nto assure a smooth and timely migration to the new environment (i.e.,<br \/>\ntypically capable of being performed overnight).<\/p>\n<p>          c.   SECOND LEVEL SUPPORT.    UPS shall be solely responsible for<br \/>\nproviding all first level support for its end user customers and for all aspects<br \/>\nof the Messaging Service which do not involve the Software.  Except as set forth<br \/>\nin Section 9(d) below UPS shall further be responsible for first level support<br \/>\nof the Server Software and Custom Server Software.  Tumbleweed will provide to<br \/>\nUPS, twenty-four (24) hours per day, seven (7) days per week, all telephone or<br \/>\nwritten consultation reasonably requested by UPS in connection with its use and<br \/>\noperation of the Software or any problems therewith which cannot be resolved a<br \/>\nthe first level.

To the extent that UPS declines or fails to<br \/>\nimplement the Minimum Conditions (as defined above), Tumbleweed shall not be<br \/>\nliable for any response time commitments and associated remedies set forth in<br \/>\nSections 9(e)(ii) and (iii).  During the first five (5) days following<br \/>\ninstallation of the Software at each Supported Datacenter, the DSP shall be<br \/>\nphysically present during UPS Business Hours to assist with the implementation<br \/>\nof the Messaging Service at such Supported Datacenter.<\/p>\n<p>          e.   REMEDIAL EFFORTS BY TUMBLEWEED.    Tumbleweed will respond to and<br \/>\nresolve problems with the Software in accordance with the following procedures:<\/p>\n<p>     i.   UPS shall first attempt to identify and rectify the problem in<br \/>\n          accordance with its first-level support obligations, which may include<br \/>\n          consulting with the DSP.  If such activities are unsuccessful, the DSP<br \/>\n          (or one of UPS&#8217;s Support Interfaces, if UPS is not then covered by<br \/>\n          Tumbleweed&#8217;s DSP Services pursuant to Section 9(d) above) shall<br \/>\n          contact Tumbleweed to report such problem.  If the problem may be<br \/>\n          solved via a telephone consultation, Tumbleweed (or its DSP) shall<br \/>\n          proceed to attempt to effect such resolution.

PUBLICITY.  Tumbleweed shall not use the name of or refer to UPS<br \/>\nor any of its Affiliates directly or indirectly in any advertisement, press<br \/>\nrelease or professional or trade publication without receiving prior written<br \/>\napproval from UPS.  Notwithstanding the foregoing, and subject to Tumbleweed&#8217;s<br \/>\ncompliance with the applicable restrictions and other obligations hereunder<br \/>\n(e.g., restrictions on the disclosure of UPS&#8217;s Confidential Information), UPS<br \/>\nwill agree to be a reference account for Tumbleweed and will allow Tumbleweed to<br \/>\npromote its relationship with UPS in press releases, web pages and other<br \/>\ncollateral marketing and sales materials; provided, however, that Tumbleweed<br \/>\nmust obtain UPS&#8217;s prior written consent with respect to any and all such<br \/>\ndescriptions of the relationship between UPS and Tumbleweed, which consent will<br \/>\nnot be unreasonably withheld.<\/p>\n<p>          e.

Such inspections and testing shall be at<br \/>\n          UPS&#8217;s expense and shall be conducted at Tumbleweed&#8217;s premises or at<br \/>\n          such other location as Tumbleweed may approve, which approval shall<br \/>\n          not be unreasonably withheld.<\/p>\n<p>                                  Section 3<br \/>\n                            TITLE TO SOURCE CODE<\/p>\n<p>     Title to the Source Code shall remain in Tumbleweed, but title to the media<br \/>\nupon which the Source Code is stored to be deposited in escrow hereunder shall<br \/>\npass to, and vest in, Escrow Agent immediately upon delivery, and in the event<br \/>\nthe Source Code shall be delivered to UPS pursuant hereto, title to the media<br \/>\nupon which the Source Code is stored shall thereupon pass to and vest in UPS.<br \/>\nNotwithstanding it ownership of a copy of the Source Code in such event, UPS<br \/>\nshall remain subject to the terms of the license granted pursuant to Section<br \/>\n11(e) of the License Agreement with respect to the Use thereof.<\/p>\n<p>                                  Section 4<br \/>\n                        RELEASE OF SOURCE CODE TO UPS<\/p>\n<p>     4.1  NOTICE OF DEFAULT; RIGHT TO CURE.  If UPS shall conclude in good faith<br \/>\nthat a release event set forth in Section 11(a) of the License Agreement has<br \/>\noccurred (including Tumbleweed&#8217;s failure in any material respect to provide any<br \/>\nSupport Services that it is obligated to provide, and such failure has resulted<br \/>\nin UPS&#8217;s inability to use any of the major functional components of the<br \/>\nSoftware), it shall so notify Tumbleweed in writing (the &#8220;Initial Notice&#8221;).<br \/>\nSuch notice shall describe such failure in reasonable detail.  A copy of such<br \/>\nInitial Notice shall be simultaneously delivered to Escrow Agent.  For a period<br \/>\nof twenty (20) days after receipt of such Initial Notice, Tumbleweed shall have<br \/>\nthe right to cure the identified failure.  In the event that, at the conclusion<br \/>\nof such cure period, UPS shall conclude in good faith that the identified<br \/>\nfailures have not been cured, UPS may so notify both Tumbleweed and Escrow Agent<br \/>\nin writing and demand that Escrow Agent release the Source Code to UPS (the<br \/>\n&#8220;Final Notice&#8221;).

Tumbleweed may so notify Escrow Agent and UPS<br \/>\nin writing within four (4) business days after receipt of UPS&#8217;s Final Notice<br \/>\ndemanding release of the Source Code.  Failure of Tumbleweed to give timely<br \/>\nnotice of such an objection shall conclusively establish its consent to the<br \/>\nrelease of the Source Code to UPS hereunder, whereupon Escrow Agent shall<br \/>\npromptly release a copy of the Source Code to UPS.  In the event of a dispute,<br \/>\nEscrow Agent will continue to store the Source Code without <\/p>\n<p>UPS\/Tumbleweed Confidential                                    December 18, 1997<\/p>\n<p>release, pending (a) joint instructions from UPS and Tumbleweed, (b) resolution<br \/>\npursuant to Section 5, or (c) order of a court.<\/p>\n<p>     4.3  INJUNCTIVE RELIEF.  Tumbleweed and UPS acknowledge and agree that UPS<br \/>\nmay suffer irreparable harm to its business and operations in the event that<br \/>\nrelease of the Source Code to UPS pursuant to the terms hereof is wrongfully<br \/>\ndelayed by Tumbleweed, and that UPS may petition for injunctive relief to<br \/>\nprevent Tumbleweed from seeking to delay such release.<\/p>\n<p>                                  Section 5<br \/>\n          ARBITRATION OF DISPUTES RESPECTING RELEASE OF SOURCE CODE<\/p>\n<p>     5.1  ARBITRATION OF DISPUTES.
