2. Confidential Information

"Confidential Information" means non-public information one party discloses to the other for the Purpose, in any form, that is marked confidential or that a reasonable person would treat as confidential. It includes technical data, product plans, customer information, prices, financial information and the existence and terms of the parties’ discussions.

5. No obligation to proceed

Neither party is required to share any particular information or to enter into any further agreement. Either party may end the discussions at any time by written notice.

What the law says

A mutual NDA is a contract under state law, like any NDA. Courts check that the information is defined and that the duty has a reasonable end.

The ESIGN Act makes an electronic signature as valid as ink. Both companies can sign from different cities and keep the same signed PDF.

If any person on either side signs in their own name as a worker or consultant, the Defend Trade Secrets Act notice in clause 10 protects the remedies of the company that shares.

Mutual NDA or one-way NDA

Use a mutual NDA when both sides will open their books. Two software companies planning an integration need one. So do a buyer and a seller in an acquisition.

Use a one-way NDA when only you share. A founder pitching an investor is the classic case. The mutual version is not stricter. It applies the same duties to both parties.

Protect the talks, not only the documents

Clause 2 covers the existence and terms of the discussions. A leak that two companies are talking can move prices, staff and customers. This line keeps the talks private too.

Disclosure window and secrecy period

The template has two clocks. The first is the window during which shared information is covered. The second is how long each side must keep it secret after the last disclosure.

A one-year window and three years of secrecy fit most partnership talks. Raise both for long technical projects.

Mistakes that weaken a mutual NDA

  • A vague purpose. Each side can then argue that any use was allowed.
  • Different versions signed by each side. Sign one document so both hold the same text.
  • No exit. Clause 5 lets either side walk away without breaking the agreement.
  • Signing after the first call. Anything shared before signing may fall outside the agreement.

How to run the exchange after signing

Name one contact on each side who sends and receives documents. Mark files as confidential in the name or the first page. Share them from a folder with access logs.

When the talks end, ask for the return or destruction under clause 7. Keep the written confirmation with the signed agreement.

If the talks turn into a deal, the final contract usually replaces this NDA for the new work. Check that it keeps the secrecy period for what you already shared.

Signing with a company in another state or country

Pick one governing law in clause 11 and write it out in full. Both signers can be in different places. Each one signs from their own phone and both keep the same signed PDF.
