If Customer does not meet one of these qualifications, Customer has no rights under this Agreement. Non-educational research conducted using the facilities of an academic institution or under an academic name does not qualify and represents a violation of the terms of this Agreement. 1.2 Designated Country/Computers/Networks. Subject to Section 1.3, Customer may only install and operate Licensed Products on the applicable Designated Computers or Designated Networks on computer systems and networks situated in the applicable Designated Country. Customer may, from time to time, change the Designated Computer, Designated Network, and/or the Designated Country in which Customer seeks to install or operate a Licensed Product, provided that in each case (i) Customer shall give prior written notice to PTC of any such change, and (ii) upon moving the Licensed Products to a different Designated Country, Customer shall pay all applicable PTC transfer fees and/or Uplift Fees, as well as any taxes, tariffs or duties that may be payable as a result of such move (collectively, the "Relocation Charges"). 1.3 Global/Restricted Global Licenses. If the Licensed Product is being Licensed on a "Global" or "Restricted Global" basis, Section 1.2 shall not apply to such Licensed Products and the following provisions shall apply instead: (i) Global Licenses.

Registered User Products may only be used by Registered Users. Customer may add and/or substitute from time to time new Registered Users as long as the aggregate number of Registered Users does not exceed at any point in time the number of Licenses in effect at such time for that particular Licensed Product and, provided further, that if a person who was previously a Registered User returns to Registered User status, a new License fee must be paid to PTC at PTC's then current rates. 1.7 Additional Restrictions on Use Applicable to Designated Server Products.

If the Customer's License is a "home use" License, such Licensed Product is only for use within the home of an employee or contractor of Customer who is the sole user of a separate Arbortext Editor License. Notwithstanding anything to the contrary in this Agreement, the Arbortext IsoView Licensed Product and the Arbortext IsoCompose Licensed Products permit the Customer to sublicense the applicable installation program and included runtime components, as bundled in IsoView or IsoCompose applications developed by the Customer to Customer's end users, solely for use in connection with such applications, without the right to further sublicense. Such installation programs must be protected by requiring the use of a restricted password if Customer installs such installation program on Customer's webpage(s) for presentation of illustrations. Any such sublicense may only be granted to an end user who agrees to abide by all of the terms and conditions of the License Agreement with respect to such use. Customer shall not remove any proprietary notices or labels contained in the IsoView or IsoCompose Applications and shall include a valid copyright notice with each copy of Customer's IsoView or IsoCompose Application.

After this Licensed Software is assigned to a Registered User, the License may not be re-assigned to any other user even if the original Registered User ceases to be employed by the Customer. Regarding Upgraded Use: If the Licensed Software was licensed as an upgrade from a previous version, Customer must first be licensed for the Licensed Software identified by PTC as eligible for the upgrade. After installing the upgrade, Licensed Software licensed as an upgrade replaces and/or supplements the product that formed the basis of Customer's eligibility for the upgrade and Customer may no longer use the original Licensed Software that formed the basis for Customer's upgrade eligibility. 2. Audit. To confirm Customer's compliance with the terms and conditions hereof, Customer agrees that PTC may audit Customer's use of the Licensed Products. Customer agrees to provide PTC access to Customer's facilities and computer systems, and cooperation from Customer's employees and consultants, as reasonably requested by PTC in order to perform such audit, all during normal business hours, and after reasonable prior notice from PTC. 3. Intellectual Property. PTC and its licensors are the sole owners of the Licensed Products and of any copies of the Licensed Products, and of all copyright, trade secret, patent, trademark and other intellectual or industrial property rights in and to the Licensed Products. All copies of the Licensed Products, in whatever form provided by PTC or made by Customer, shall remain the property of PTC, and such copies shall be deemed to be on loan to Customer during the License Term. Customer acknowledges that the License granted hereunder does not provide Customer with title to or ownership of the Licensed Products or any copies thereof, but only a right of limited use consistent with the express terms and conditions of this Agreement. Customer shall have no rights to the source code for the Licensed Products and Customer agrees that only PTC shall have the right to maintain, enhance, or otherwise modify the Licensed Products. 4. Maintenance; Warranty; Disclaimer of Warranties. 4.1 Maintenance. A Maintenance plan may not be cancelled by Customer following PTC's acceptance of the order therefor. PTC and/or its authorized subcontractors shall provide Maintenance Services at the appropriate level in accordance with the policies at http://www.ptc.com/support/maintenance/maintenance_support_policies.htm. If Customer does not order Maintenance Services to commence on shipment of the Licensed Product(s) and on a continuing basis thereafter, and subsequently wishes to obtain Maintenance Services, Customer must pay (i) the then current fees for Maintenance Services and (ii) the fees for Maintenance Services for any period for which Customer has not purchased Maintenance Services. With respect to Registered User Products, annual Maintenance Services ordered by Customer must cover all Licenses granted to Customer for such Licensed Products. The services offered under any Maintenance plan may change from time to time, and PTC may cease to offer such maintenance or Maintenance plans at any time without notice, subject only to the obligation to refund to Customer the unused portion of any previously paid applicable maintenance fee (on a prorated basis). 4.2 Warranty.

PTC's and its licensors' entire liability and Customer's exclusive remedy for any breach by PTC of the warranty given in Section 4.2 above shall be, at PTC's sole discretion, either to (a) replace the Licensed Product(s) or (b) use diligent efforts to repair the Error. PTC's obligations set forth in the preceding sentence shall apply only if notice of the Error is received by PTC within the Warranty Period and Customer supplies such additional information regarding the Error as PTC may reasonably request. If PTC does not replace the applicable Licensed Product(s) and/or does not repair the Error (either by providing a bug fix, a workaround or otherwise) within a reasonable time after notice of the Error and associated information from Customer is received by PTC, PTC will provide a refund of the license fees paid by Customer for the applicable Licensed Product(s) upon return of such Licensed Product(s) and any copies made thereof. 4.5 No Additional Warranties. No employee, partner, distributor (including any Reseller) or agent of PTC or any of its resellers or sales agents is authorized to give representations, warranties or covenants greater or different than those contained in this Agreement, except as specifically set forth in a written agreement signed on behalf of Customer by an authorized officer and on behalf of PTC by its legal counsel or Corporate Controller. 4.6 Disclaimer of Warranties.

Indemnification; Infringement. 5.1 PTC's Obligation to Indemnify Customer. PTC, at its own expense, will defend any action brought against Customer based on a claim that any Licensed Product infringes a United States patent, copyright or trademark and, at its option, will settle any such action or will pay any final judgment awarded against Customer, provided that: (a) PTC shall be notified promptly in writing by Customer of any notice of any such claim; (b) PTC shall have the sole control of the defense of any action on such claim and all negotiations for its settlement or compromise and shall bear the costs of the same (save where one or more of the exclusions in Section 5.3 applies); and (c) Customer shall cooperate fully at PTC's expense with PTC in the defense, settlement or compromise of such claim. 5.2 PTC's Right to Act to Prevent a Claim.

PTC shall have no liability to Customer under Section 5.1 hereof or otherwise to the extent that any infringement or claim thereof is based upon: (a) use of the Licensed Product in combination with equipment or software not supplied hereunder where the Licensed Product itself would not be infringing; (b) use of the Licensed Product in an application or environment for which it was not designed or not contemplated under this Agreement; (c) use of other than a current release of the Licensed Product(s) provided to Customer; (d) modification of the Licensed Product by anyone other than PTC or its employees or agents; or (e) any claims of infringement of any patent, copyright, trade secret, trademark or other proprietary right in which Customer has an interest. 6. Limitation of Liability. The warranty and indemnification provisions of Sections 4 and 5 hereof state the entire liability of PTC, its subsidiaries and affiliates, and each of their respective directors, officers, employees or agents, with respect to the Licensed Products and Services, including (without limitation) any liability for breach of warranty, or for infringement or alleged infringement of patent, copyrights, trademarks, trade secrets and other intellectual or proprietary rights by the Licensed Products, or their use. Except as set forth in Section 5.1 above, PTC's maximum liability arising out of, or relating to, the creation, license, functioning, use or supply of the Licensed Products or the provision of Services or otherwise relating to this Agreement, whether based upon warranty, contract, tort, or otherwise, shall not exceed to the lesser of the fees paid by Customer for the Licensed Products or Services that gave rise to the claim or PTC's list price for such Licensed Products or Services at the time of the order therefor. IN NO EVENT SHALL PTC, ITS AFFILIATES (INCLUDING ITS SUBSIDIARY COMPANIES), OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS BE LIABLE FOR: (A) ANY LOSS OF PROFIT, LOSS OF USE DAMAGES, LOSS OF GOODWILL, LOSS OF BUSINESS OPPORTUNITY, LOSS OF SALES, LOSS OF REPUTATION OR LOSS OF ANTICIPATED SAVINGS; (B) ANY LOSS OR INACCURACY OF DATA OR BUSINESS INFORMATION OR FAILURE OR INADEQUACY OF ANY SECURITY SYSTEM OR FEATURE; AND (C) SPECIAL, INCIDENTAL, INDIRECT, PUNITIVE OR CONSEQUENTIAL LOSS OR DAMAGE HOWSOEVER CAUSED; IN EACH CASE EVEN IF PTC HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. Customer agrees not to bring any suit or action against PTC, and/or its subsidiaries and affiliates, and/or any of their respective directors, officers, employees or agents for any reason whatsoever more than one year after the cause of action arises. Customer recognizes that fees paid by Customer for the Licensed Products are based in part on the disclaimer of warranty and limitation of liability provisions set forth herein and that, in the absence of Customer's agreement to such terms, the charges for the Licensed Products would be significantly higher. The limitations and exclusions set forth in this Section 6 shall not apply to any claim in respect of death or personal injury. 7. Term and Termination. 7.1 Events Causing Termination.

It is intended that this Agreement shall not violate any applicable law and the unenforceability or invalidity of any provision (other than the provisions obligating Customer to make payments to PTC) shall not affect the force and validity of the remaining provisions and such provisions determined to be invalid shall be deemed severed from this Agreement and, to the extent possible, be replaced with terms which as closely as possible approximate the interest and economic intent of such invalid provisions. 8.6 Entire Agreement. This Agreement is the complete and exclusive statement of the contract between PTC and Customer with respect to the subject matter hereof. No waiver, consent, modification, amendment or change of this Agreement shall be binding unless in writing and signed or otherwise expressly acknowledged by PTC and Customer. 8.7 Third Party Beneficiaries.
