AI Avatar Addendum

This Addendum is made on November 10, 2026 between [Brand company legal name] (the “Brand”) and [Expert full name, credentials] (the “Expert”), and forms part of the Expert Review and Endorsement Licence Agreement dated November 10, 2026 between them (the “Agreement”). Terms defined in the Agreement have the same meaning here.

1. When this Addendum applies

1.1. An AI avatar is offered only if both the Expert and the Brand choose it. Neither Party is required to agree to it, and no other right, review or payment under the Agreement depends on it.

1.2. “AI Avatar” means any computer-generated or computer-altered image, video, voice or likeness of the Expert that depicts the Expert saying or doing something the Expert did not actually record in that form, including a digital replica within the meaning of California Labor Code section 927 and New York General Obligations Law section 5-302.

1.3. “Source Materials” means the photos, video and voice recordings of the Expert made or supplied to create the AI Avatar, and “Avatar Model” means any model, template or data set derived from them.

2. Specific permitted uses

2.1. The Brand may create and use the AI Avatar only for the specific uses listed in the Use Table in Annex 1. Any use not listed there is not permitted. A new use requires a new signed Use Table entry.

2.2. Every use must be limited to the product, Approved Claims or General Content, channels, Territory and Licence Term stated in the relevant Licence Schedule.

3. Creation and security

3.1. The Brand will create the AI Avatar only with the vendor named in Annex 1, under a written contract that: (a) limits use of the Source Materials and Avatar Model to this Addendum; (b) prohibits using them to train or improve any general model; (c) requires appropriate security; and (d) requires deletion on the Brand's instruction.

3.2. The Source Materials and Avatar Model are used only for the permitted uses. The Expert keeps all rights in their name, image, likeness and voice. The Brand owns the copyright in the finished Avatar Assets, subject to the Agreement and this Addendum.

3.3. The Brand will not use the AI Avatar in any live, interactive or real-time format (including chatbots, voice assistants, calls or personalised messages generated on demand) unless that use is expressly listed in the Use Table.

4. Scripts and approval

4.1. An AI Avatar may only say Approved Claims or General Content, using a script the Expert has approved in writing.

4.2. The Expert must approve every final rendered Avatar Asset, including every variant, language version, edit and cut-down, on the Platform before it is published. Silence is not approval.

4.3. The AI Avatar must not: (a) give individual medical advice; (b) appear to speak live or answer questions as the Expert; (c) speak in a language not listed in the Use Table; (d) mention any other product, company, person or cause; or (e) appear in political, sexual, violent or otherwise sensitive content.

5. Labelling

5.1. Every Avatar Asset will carry, for its full duration, a clear and conspicuous label stating that it is AI-generated, in addition to the paid partnership disclosure required by the Disclosure Policy, for example: “AI-generated likeness of Dr. [Name], used with permission. Paid partner of [Brand].”

5.2. The Brand will comply with any additional disclosure required by law in the jurisdiction where the Avatar Asset is shown, including New York requirements for synthetic performers in advertisements.

6. Fee

6.1. The AI Avatar fee is stated in the Licence Schedule, separately from any other Licensed Right, and is paid in advance for each Licence Term.

7. Withdrawal, expiry and deletion

7.1. The withdrawal rights in clause 7 of the Agreement apply equally to the AI Avatar: thirty (30) days' notice without cause and forty-eight (48) hours' notice for cause.

7.2. On withdrawal or expiry, the Brand will complete the takedown steps in the Agreement and, within thirty (30) days, permanently delete the Source Materials and Avatar Model and procure the same from its vendor, and confirm deletion in writing through the Platform. The Brand may keep one archived copy of each published Avatar Asset only as needed to defend legal claims, and will not use it for any other purpose.

8. Independent advice

8.1. Before signing, the Expert confirms one of the following (tick one):

☐ I was represented by my own legal counsel in negotiating this Addendum. Counsel name: __________________

☐ I was represented by a labour union representing me with respect to digital replica rights. Union: __________________

☐ I have read and understood the plain-language explanation in Annex 2, I was offered the opportunity to take independent legal advice at the Brand's cost, and I chose not to.

8.2. The Brand will reimburse reasonable fees, up to USD [amount], for independent legal advice on this Addendum.

9. Indemnity and general

9.1. The Brand's indemnity in clause 10.1 of the Agreement covers all claims arising from the creation or use of the AI Avatar, including any use beyond this Addendum or by its vendor. The liability limits in the Agreement do not apply to use of the AI Avatar beyond this Addendum.

9.2. If this Addendum conflicts with the Agreement on the AI Avatar, this Addendum prevails.

9.3. This Addendum is governed by the same law and dispute resolution as the Agreement.

ANNEX 2. PLAIN-LANGUAGE EXPLANATION FOR THE EXPERT

• What you are agreeing to: the Brand may create a computer-generated version of your face and voice and use it only in the ads listed in Annex 1.

• It can only say words you approved: your Approved Claims or General Content, using scripts you approve. You will see and approve every final video before it is published.

• It cannot talk live, answer questions, give medical advice, speak other languages, or mention other products, unless a specific use is listed and you agreed to it.

• Every avatar ad is labelled as AI-generated and as a paid partnership.

• You are paid a separate fee in advance for each term.

• You can withdraw at any time: 30 days' notice for any reason, or 48 hours for a serious reason. The ads come down and your source recordings and avatar model are deleted within 30 days.

• Your recordings are not used to train any general AI model.

• You can take independent legal advice, and the Brand will pay for it up to the stated amount. Laws in California and New York give extra protection to people whose digital replicas are used under contract.
