“Trustee” or “Trustees” means, subject to the provisions of Article VI below, the Initial Trustees, and any individual that becomes a successor Trustee hereunder. The use of the singular “Trustee” herein may refer to one or more Trustees.


The Beneficiary of the Trust shall be the IETF as a whole and not any individuals who may participate in IETF activities or either of the Settlors. In the event that the IETF ceases to, or plans to cease to, develop technical standards for the Internet, then upon and only upon the express written consent of the IESG, or the IESG’s successor as the leadership of the IETF, the IETF’s successor with respect to the development of technical standards for the Internet shall become the successor Beneficiary under this Trust; provided that neither of the Settlors nor any affiliate of either Settlor shall become such successor organization or successor Beneficiary, and provided, further, that if either the IESG or its successor does not consent to the IETF’s successor becoming the beneficiary hereunder, or if neither the IESG nor its successor are then existing, the successor Beneficiary shall be jointly designated by the Settlors.


5.1 Contribution of IPR. Settlors hereby transfer to the Trust on the Effective Date, except as otherwise provided in Schedule A, without representation or warranty on an “AS IS”, quitclaim basis, all of their right, title and interest, if any, in and to their respective IPR. For the avoidance of doubt, Settlors acknowledge that the IPR that each shall so contribute to the Trust may include IPR developed by or on behalf of IETF. On and/or after the Effective Date, as the case may be, the Trust shall have the full ownership and enjoyment of the IPR. Settlors shall promptly thereafter make the necessary arrangements to record the transfers of their respective rights and interests in the IPR, as reasonably required by the Trustees.

5.2 Contribution or License of Other Property. The Trustees will encourage others who may hold rights and interests in intellectual property, domain names or other property relevant to the IETF to similarly transfer all of their respective right, title and interest therein to the Trust, including by licensing to the Trust (preferably on a perpetual, irrevocable, worldwide, royalty-free basis), with the right to sublicense, rights to practice their inventions and patents, which the Trust may use and license to third parties in accordance with Section 9.5 of this Agreement; provided, however, that no contribution, transfer, or license of such rights or interests shall be deemed accepted as part of the Trust Assets unless the Trustees have affirmatively, in writing, accepted the applicable right or interest.

5.3 Bank Account; Additional Contributions. The Trustees shall, promptly after the execution of this Agreement, establish and maintain a bank account in the name of the Trust and may receive funds for the Trust, as appropriate, to be held in such bank account. Any Person may contribute additional funds as well as property to the Trust; provided, however, that acceptance of any contributions to the Trust shall be subject to the approval of the Trustees. Any solicitation of funds shall be done in accordance with applicable legal requirements, including requirements related to registration or fundraising (to the extent applicable).


6.1 Trustees; Successor Trustees.

(a) The Trust shall normally have five Trustees:

i. Three Trustees shall be appointed by the IETF NomCom and confirmed by the IESG. The term for Trustees appointed by the IETF NomCom shall be three years, except the initial three Trustees appointed by the IETF NomCom will be appointed for one, two and three years respectively.

ii. One Trustee shall be appointed by the IESG. The term for this Trustee will be two years, except the initial Trustee appointed by the IESG will be appointed for a one year term.

iii. One Trustee shall be appointed by ISOC. The term for this Trustee will be two years.

(b) The Trustees serving as of the Second Amendment Date will remain Trustees until five Trustees have been appointed in accordance with the process described in Section 6.1(a) above, and each of the these Trustees have agreed in writing to serve as Trustees hereunder. Upon such agreement by five Trustees appointed pursuant to Section 6.1(a), any remaining Trustees not so appointed will automatically be removed as Trustees.

(c) A Trustee appointed by the IETF NomCom may be recalled in accordance with BCP 10 and any duly approved successor documents thereto. Trustees appointed by the IESG or by the ISOC Board of Directors may be recalled by the appointing body. If the final conclusion of the applicable recall process is that a Trustee should be removed as a Trustee, that Trustee will be automatically removed as of the date of such conclusion.

(d) In the event that a Trustee position is vacated, the appointing body may appoint a replacement to serve the remainder of the terms of the vacating Trustee. Upon appointment and confirmation by the appropriate nominating body(ies) specified in Section 6.1(a), and agreement in writing to serve as a Trustee hereunder, the appointed replacement will be a Trustee.

(e) Unless they otherwise vacate the position, a Trustee appointed pursuant to Section 6.1(a) will serve until their replacement is duly appointed and agrees to serve as a Trustee hereunder. At such time the replaced Trustee will be automatically removed as a Trustee.

(f) Notwithstanding the foregoing, if for any reason there are fewer than three individuals serving as Trustees, then the IESG, or the IESG’s successor as the leadership of the IETF, shall appoint one or more individuals to serve in a temporary capacity as Trustee(s) until successors are appointed and confirmed by the appropriate nominating body(ies) specified in Section 6.1(a), so that there are at least three Trustees at all times.

(g) Any successor Trustee shall succeed to all of the powers, authorities, rights, discretions, immunities, estates, titles, duties and obligations of a Trustee hereunder, without the necessity of any conveyance or the taking of any action whatsoever.

6.2 Qualification. No Person shall be required to be a resident of the Commonwealth of Virginia in order to be a Trustee. To the maximum extent permitted by law, no Trustee, whether or not a resident of the Commonwealth of Virginia or otherwise, shall be required to:

a. take actions or meet requirements to qualify as a Trustee other than as required by Section 6.1(a);

b. in the case of a Person that is not a resident of the Commonwealth of Virginia, file any submission to jurisdiction or appoint any agent for service of process in the Commonwealth of Virginia;

c. furnish any bond or surety; or

d. issue or make accounts with respect to the Trust or the property contained therein or for their actions as a Trustee, to a Commissioner of Accounts or any other Person, either upon becoming a Trustee or from time to time thereafter.

Notwithstanding the foregoing, to the extent that applicable law requires any Trustee to undertake any of the actions described in items (a) to (d) above, such Trustee hereby agrees (1) to submit to jurisdiction in the Commonwealth of Virginia (in the case of item (b)), (2) to undertake such action and (3) to file with the appropriate Person any documents, instruments, agreements or certificates required in connection therewith.


7.1 Powers and Obligations of Trustees.

(a) Except as limited by this Agreement, the Trustees shall have all powers granted by law and shall be responsible for and may take such actions as are required to assure the effective day-to-day operation of the Trust. However, except as otherwise expressly permitted hereunder, the Trustees shall not, and shall not have the right or power to, (i) exchange, distribute, assign, sell, transfer, renounce, or convey, the Trust Assets, (ii) terminate the Trust Assets’ registration, or (iii) enter into a license for, grant an option on, or encumber the Trust Assets that is not in compliance with the provisions of Section 9.5, except that in the case of clauses (i) and (ii), the Trustees may, after due consultation with the Beneficiary, dispose of, assign, sell, transfer, renounce, convey or terminate Trust Assets that are of no current or foreseeable future value to the Beneficiary and which require the expenditure of funds to retain. This exception does not include RFCs.

(b) As promptly as reasonably practical following the Effective Date, the Trustees shall publish, or have published, procedures for administration of the Trust, reimbursement by Trustees of their fees and expenses from the Trust, management of the Trust Assets, conflicts of interest and standards of conduct. Thereafter, the Trustees may amend such procedures from time to time.

(c) The Trustees shall use reasonable efforts to secure contributions or commitments from third parties to contribute or make available sufficient funds to or on behalf of the Trust to administer the Trust and to maintain the Trust Assets at least until July 1, 2010, including but not limited to the payment of filing and maintenance fees for the Trust Assets as deemed reasonable and appropriate.

(d) It is the express intent of the Settlors that this Trust not become (and any court not order that this Trust be) invalid or terminated or the Trust Assets be released from trust, except as expressly permitted by Section 10.1.

(e) The Trustees shall report annually to the IETF community concerning the activities of the Trust, including grants or licenses given by the Trust, demonstrating that the Trust is being operated in furtherance of the Purpose.

7.2 Decision-making. A quorum for a meeting of the Trustees shall be a majority of the Trustees then in office. Except as otherwise provided in this Agreement all decisions of the Trustees must be approved by majority vote of the Trustees then in office.

7.3 Delegation. The Trustees shall have the authority to delegate certain duties and responsibilities of administering the Trust to other individuals or entities who shall remain under the supervision, direction and control of the Trustees. The Trust shall have the authority to contract with third parties to carry out any actions necessary to acquire, hold, maintain and license Trust Assets subject to the limitations of this Agreement. No such delegation or third party shall permit any other Person to take any action that would not be permitted to be taken by a Trustee or the Trustees hereunder.

7.4 No Prudent Investor Standard. The Trustees shall not be required to follow the “prudent investor” or any similar rule, and in particular, the “prudent investor” or any similar rule shall not constitute, or be deemed to constitute, a basis for the exchange, distribution, assignment, sale, transfer, conveyance, grant of an option on, or encumbrance on the Trust Assets. In addition, the Trustees shall not be under any obligation to diversify the Trust Assets.

7.5 No Liability for Acts of Predecessor Trustee. No Trustee shall be responsible or liable for the acts or omissions of any predecessor Trustee, or of a custodian, agent, depositary or counsel selected with reasonable care.

7.6 Fees and Expenses of Trustees. The Trustees are collectively authorized to reimburse themselves from the Trust for reasonable expenses incurred in the administration of the Trust, upon promulgation of, and in accordance with, the procedures therefore referred to above in Section 7.l(b).

7.7 Limitation on Trustee Liability. No Trustee shall be liable to the Trust or any other person for monetary or other damages for breach of fiduciary duty as a Trustee to the maximum extent permitted by Virginia law; provided, however, that this provision shall not limit the liability of a Trustee (a) for any breach of the Trustee’s duty of loyalty to the Trust or (b) as otherwise required by Virginia law. If Virginia law be hereafter amended to authorize the further elimination or limitation of liability of Trustees, then the liability of the Trustees shall be limited to the fullest extent permitted by Virginia law, as so amended, and such elimination or limitation of liability shall be in addition to, and not in lieu of, the limitation on liability provided in the previous sentence. Any repeal or amendment of this section shall be of prospective effect only and shall not adversely affect any limitation on the liability of the Trustee existing at the time of such repeal or amendment.


8.1 Term. The Trust shall be for an indefinite term; provided, however, that, if this Agreement would be unenforceable in the event that it were to continue in perpetuity or otherwise violate the Rule against Perpetuities, then the term of this Agreement shall be limited to the maximum period permitted by law. Notwithstanding the foregoing, on or after July 1, 2010, the Trustees, acting by at least a two-thirds majority vote, may elect to terminate the Trust.

8.2 Distributions Upon Dissolution. Upon the termination or dissolution of the Trust for any reason, the Trust Assets shall be distributed to an organization to be used in furtherance of the Purpose, after the payment or making provisions for the payment of all of the liabilities of the Trust; provided that neither of the Settlors nor any affiliate of either Settlor shall so receive any Trust Assets. Any such Trust Assets not so disposed of shall be disposed of by a court of competent jurisdiction of the county in which the principal office of the Trust is then located, exclusively for such Purpose.


9.1 Income. After payment of all expenses of administering the Trust and maintaining the Trust Assets, any part or all of the net income of the Trust may, in the absolute discretion of the Trustees, be retained or paid to or applied for the benefit of the Beneficiary to be used in furtherance of the Purpose, at such intervals and in such amounts as the Trustees from time to time deem requisite or desirable and/or to comply with any applicable legal requirements. Any net income not paid or applied shall be added to and become a part of the principal of the Trust.

9.2 Principal. After payment of all expenses of administering the Trust and maintaining the Trust Assets, in the absolute discretion of the Trustees, the principal shall be retained or used in furtherance of the Purpose, at such intervals and in such amounts, as the Trustees from time to time deem requisite or desirable and/or to comply with any applicable legal requirements (it being understood and agreed that this section shall not override, and shall be subject to, the provisions of Sections 7.1 and 7.3).

9.3 Expenses. The Trustees shall pay from amounts contributed by third parties or from the Trust Assets the expenses of administering the Trust, which may include, but shall not be limited to, the reasonable costs of administering the Trust, including legal and accounting fees, as appropriate, the payment of filing fees and maintenance fees for the Trust Assets, and the reasonable costs incurred in administering the Trust. In no event may the Trustees liquidate or distribute IPR in order to pay such expenses, to pay any tax or to acquire or maintain any exemption from federal income tax under Section 50l(c)(3) of the Code or to comply with the minimum distribution requirements of Section 4942 of the Code.

9.4 Maintenance of the Trust Assets. The Trustees shall take reasonable steps to maintain the value, validity and enforceability of the Trust Assets that are subject to registration, including by filing affidavits of continued use and applying for all renewals to the extent permitted by applicable law. The Trustees shall have the right to prepare, file and prosecute registration applications in the Trust’s name, as the Trustees deem necessary in order to maintain and protect the Trust Assets.

9.5 Licenses. The Trust (acting through the Trustees) shall have the right to grant licenses for the use of the Trust Assets on such terms, subject to Section 7.1, as the Trustees deem appropriate; provided, however, that the Trust shall not grant any license that would be deemed a transfer of ownership or abandonment of any Trust Assets under applicable law. Specifically, any license granted by the Trust for the use of the Trust Assets consisting of IPR other than rights in IETF standards- related documents (such as RFCs, Internet Drafts and the like) that have been acquired by the Trust through non-exclusive licenses granted by their contributors pursuant to the IETF community-approved procedures currently set forth in RFC 3978, and any community- approved updates and revisions thereto, shall include provisions stating that (a) the licensee agrees to grant and assign to the Trust all right, title, and interest it may have or claim in any derivative works of licensee that are based on or incorporate the IPR, and (b) the licensee’s use of the IPR and any goodwill associated therewith shall inure to the benefit of the Trust.

9.6 Enforcement. The Trustees shall have the right to take, and to determine whether or not to take, any action(s) with respect to any unauthorized use, infringement or dilution of property included in the Trust Assets.

9.7 Use of Trust Assets. The Trust Assets shall be used solely in furtherance of the Purpose. The Trust Assets shall not inure or be payable to or for the benefit of any private individual, except that, subject to Sections 7.1, 7.3, and 9.3, the Trust shall be authorized and empowered to pay reasonable compensation for services rendered and to make payments in furtherance of the Purpose and as permitted by Section 7.6 hereof. The Trust Assets shall not be used for the carrying on of propaganda, or otherwise attempting to influence legislation. No part of the activities of the Trust shall be the participation in, or intervention in (including the publishing or distributing of statements) any political campaign on behalf of (or in opposition to) any candidate for public office. Any other provision of this Agreement to the contrary notwithstanding, the Trust shall not carry on any activities not permitted to be carried on by an organization exempt from Federal Income Tax under Section 501(a) and Section 501(c)(3) of the Code.


10.1 Amendments. Prior to July 1, 2010, this Agreement may be amended only by unanimous written consent of both of the Settlors and two-thirds of the Trustees. After July 1, 2010, the Trustees may unilaterally amend the provisions of this Agreement without the written consent of the Settlors, except that no amendment shall be made with respect to the requirement that the Trust be used in furtherance of the Purpose or subject to the provisions of Sections 2.1 and 9.7.

10.2 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the activities contemplated hereby is not affected in a manner materially adverse to the Trust. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Settlors (if prior to July 1, 2010) and the Trustees shall modify this Agreement so as to effect the Purpose as closely as possible in an acceptable manner to the end that the Purpose is fulfilled to the fullest extent possible.

10.3 Successors and Assigns; Third Party Beneficiaries. Except as expressly provided herein, neither this Agreement nor any rights or obligations hereunder may be assigned, delegated or otherwise transferred. Any attempted assignment, delegation or transfer that does not comply with the provisions of this section shall be null and void. Nothing in this Agreement, express or implied, is intended to or shall confer upon any third party any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement unless expressly provided herein.

10.4 Entire Agreement. This Agreement constitutes the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter of this Agreement.

10.5 Governing Law. This Agreement and the Trust created hereby shall be governed in accordance with the law of the Commonwealth of Virginia, without giving effect to the conflict of laws principles thereof. The original place of administration of the Trust shall be Virginia, but the place of administration of the Trust may be transferred after July 1, 2010, or from time to time thereafter, to such place or places as the Trustees deem appropriate.

10.6 Counterparts. This Agreement may be executed in counterparts, each of which, including those with fax signatures, shall be deemed an original and all of which counterparts taken together shall constitute one and the same instrument.
