Contract for the Provision of Registry Services

in Relation to

Top Level Domain Names

These Proposed Terms for a Contract for the Provision of Registry Services in Relation to Top Level Domain Names ("Term Sheet") state the current status of the discussions as of September 30, 2000, and provide a framework for negotiating a definitive agreement between SRI International, Inc., 333 Ravenswood Avenue, Menlo Park California 94025 ("SRI"); NeuStar, Inc., 1120 Vermont Avenue NW, Suite 550, Washington DC 20005 ("NS"), and Melbourne IT Limited, Level 2, 120 King Street, Melbourne Victoria 3000 ("MIT").

1. Background

1.1 SRI is preparing, and intends to file a proposal ("Proposal") with ICANN for the award of an accreditation to act as Sponsor and registry for a restricted TLD in response to ICANN's invitation of 15 August 2000 ("Accreditation").

1.2 Representatives of SRI, NS and MIT have been discussing a proposed transaction under which NS and MIT would provide all or some of the registry functions necessary for purposes of the proposed registry business ("Proposed Transaction"). These functions are described in more detail in Appendix 1 to this Term Sheet ("Registry Functions").

2. Non Binding Intent

2.1 This Term Sheet summarizes the current status of the discussions and provides a framework for negotiating a definitive agreement between SRI, NS and MIT with respect to the Proposed Transaction (the "Agreement").

2.2 The provisions of this Term Sheet shall not be binding on SRI, NS and/or MIT, and shall not be deemed to create any legal rights or obligations between SRI, NS and MIT, except for Sections 2, 3, 4, 10, 12, and 14. The provisions of this Term Sheet are only intended to facilitate negotiations and preparation of the Agreement, if any.

2.3 The parties shall use good faith reasonable efforts to negotiate the Agreement, with the intent to finalize and execute the Agreement as soon as practicable after SRI has been awarded the Accreditation. However, SRI, NS and/or MIT may discontinue such negotiations at any time by written notice to the other for any reason whatsoever.

2.4 Although it is the intent of the parties that their negotiations initially proceed based on the Term Sheet, the terms contained in the Term Sheet are subject to change in the course of the planned negotiations.

2.5 Neither party shall have any liability whatsoever to the other parties for its discontinuance of the negotiations or its decision for any reason not to enter into the Agreement.

2.6 Any proposed Agreement shall be subject to all required corporate approvals of SRI, NS and MIT.

2.7 Upon execution of the Agreement, if any, the provisions of this Letter of Intent and all prior discussions shall be superseded by the Agreement.

2.8 Notwithstanding Sections 2.3 and 2.5 above, if the parties are unable to reach agreement and SRI wishes to use a third party to provide Registry Functions or any part of them, SRI shall give NS and MIT a Right of First Refusal to match the proposed terms offered by such third part(ies) as follows. For the purpose of this section 2.8, "Decision Date" shall mean the earlier of (1) three (3) months from the day when ICANN announces the award of the TLDs and (2) fifteen (15) days prior to the date set by ICANN as the last day for the TLD's to have entered into a final agreement to provide registry functions.

(a) If on or before the Decision Date, NS and MIT have a final written and executed agreement for the provision of registry functions with another TLD awarded by ICANN through its New TLD Application Process, SRI shall present to NS and MIT a written agreement that contains the firm offer of a third party, which SRI is prepared to accept. NS and MIT shall have seven (7) days from the day on which SRI presents such proposed firm offer, to return a final proposal embodying equal or equivalent terms under which NS and MIT will perform the request Registry Functions ("the NSMIT Counter"). SRI shall review the NSMIT Counter, and agrees not to reject the NSMIT Counter unless SRI determines in good faith that the proposed terms of the NSMIT Counter are not at least equivalent to those in the third party proposal. If SRI agrees to the terms of the NSMIT Counter, SRI shall execute such document. If SRI, in its reasonable discretion has rejected the NSMIT Counter, or if SRI has not received any NSMIT Counter, by midnight on the seventh day after SRI has delivered the proposed agreement to NS and MIT, SRI shall have the right to enter into the agreement with the third party on such third party terms.

(b) If on the Decision Date NS and MIT do not have a final written and executed agreement with another TLD for the provision of registry functions, then the procedure immediately above in subsection (a) shall apply, however, when NS and MIT have provided SRI with the NSMIT Counter as set forth in subsection (a), SRI shall have the right to have an independent third party ("Consultant") evaluate NS and MIT's financial fitness to fulfill their obligation to SRI under the proposed agreement before deciding whether or not to agree to the NSMIT Counter. Such evaluation will include at least an analysis of (i) operating budget viability; (ii) adequacy of capital structure; and (iii) management strength; and (iv) the extent that registry function are a significant strategic component of NS and/or MIT's business. To perform the evaluation, SRI shall identify the Consultant amongst investment bankers, or other entities, as SRI deems appropriate. NS and MIT, in good faith, shall approve of such choice within twenty-four (24) hours; such approval not to be unreasonably withheld or delayed. If NS and MIT reject the Consultant, SRI shall present an other Consultant who shall again be subject to NS and MIT's reasonable approval. SRI, NS and MIT agree to exercise their best efforts, in good faith, to identify and agree on a Consultant promptly in order not to delay this process. The Consultant, once approved, shall perform the evaluation within seven (7) days of the appointment. If the Consultant determines that NS and MIT will not have sufficient financial fitness to perform their obligations under the proposed agreement, SRI shall be entitled to enter into the registry services agreement with other proposed vendor(s) on the same terms as described in the third party firm offer that was the subject of the Right of First Refusal.

3. Expenses. Each party shall bear its own expenses including, without limitation, internal expenses and overhead costs, expenses of all attorneys, accountants, advisors, consultants and brokers retained by or representing them in connection with the negotiation and consummation of the Proposed Transaction, the preparation of the Proposal, or the negotiations with ICANN with respect to the Proposal or the Accreditation. Any actions taken by any party in reliance on this Letter of Intent shall be at such party’s sole risk and expense.

4. Prior Arrangements

4.2 SRI and NS have previously entered into a Nondisclosure Agreement dated August 23, 2000. NS has represented to SRI, and MIT has acknowledged and agreed that MIT is also bound by the terms of the Non Disclosure Agreement of August 23, 2000. The terms of the August 23, 2000 Non Disclosure Agreement are deemed incorporated into this Term Sheet. By executing this Term Sheet, and in consideration for its continued participation in the Proposal, MIT confirms its understanding that it is bound by the terms of such Non-Disclosure Agreement.

4.3 By way of clarification of the Non-Disclosure Agreement of August 23, 2000, the following "Proprietary Material" shall be deemed protected as the "Confidential Information of SRI and/or NS-MIT, as applicable" (SRI and NS/MIT each a "Disclosing Party" when providing information and a "Receiving Party" when receiving information) under the terms of the Non-Disclosure Agreement:

(i) Any and all information or data that the Disclosing Party communicates orally, visually, on paper, in written, electronic, digital or other tangible form or media; or that can be acquired through observation, inspection, review, or analysis of the Disclosing Party's property, material, documents, software, technology, written memoranda, drawings, specifications, schematics, flowcharts, graphic representations, photographs, notebook entries, software, samples, or facilities, concerning or relating to the Proposal, and the Disclosing Party's operations or strategies with respect to the subject matter of the Proposal, including, without limitation, business plan, financial plan, marketing plan, research and development plan, market information, financial information, projections, strategic information, pricing and any other information or material relating to the "dot.geo" or "geoweb" project, or the registry services related thereto, or to the subject matter of the Proposal; and

(ii) Any and all document, description, abstract, summary, or other material (in paper, electronic, digital, video, or other tangible form or media) that contains, summarizes, analyzes or relates to the information or material described in subsection (i) above, and any and all copies, abstracts, extracts or summaries thereof; and

However, either party may at any time make any disclosures required by law upon prior written notice to the other party provided that the disclosing party first gives the other party assistance as reasonably requested in obtaining an order protecting the information from disclosure. Notwithstanding the foregoing, this Term Sheet will be part of the Proposal filed on October 2, 2000 with ICANN; however, the Proposal will contain a request that ICANN keep the terms and content of this Term Sheet confidential, and do not post the portion of the Proposal containing this Term Sheet on the ICANN website, or in any other public forum.

Upon the expiration of the initial period, if SRI is granted an extension of the award, SRI agrees to retain NS and/or MIT to provide such services, and NS and/or MIT agree to provide such services on terms substantially similar to those of the Agreement. However, if SRI receives competitive proposals for such registry functions from third parties, SRI shall grant NS and MIT a right of first refusal, to be exercised not later than within seven (7) days after SRI submits to NS and/or MIT a final and firm offer from the third party.
