Official Rules

1. Sponsor

This sweepstakes (the "Sweepstakes") is sponsored and administered by Sustainable Electronics Recycling International ("SERI"), a District of Columbia nonprofit corporation exempt from federal income tax under Section 501(c)(3) of the Internal Revenue Code, with its principal place of business at 1315 Walnut St Ste 801, PMB 264, Philadelphia, PA 19107 ([email protected]). The laptops are donated by Lenovo. Lenovo is not a sponsor or administrator of this promotion.

2. Eligibility

(a) The Sweepstakes is open only to legal residents of the 50 United States and the District of Columbia, except residents of Florida, North Dakota, Oklahoma and Virginia, who are at least 18 years old and the age of majority in their state of residence (19 in Alabama and Nebraska, 21 in Mississippi) when they enter.

(b) Employees, officers, directors and contractors of SERI and of Lenovo, any agency involved in this promotion, and the immediate family members (spouse, parents, siblings and children) and household members of each of them, are not eligible.

(c) The Sweepstakes is void in Florida, North Dakota, Oklahoma and Virginia, in Puerto Rico and all other U.S. territories, outside the United States, and wherever prohibited or restricted by law.

3. Entry Period

The Sweepstakes begins at 10:00:00 a.m. Eastern Time ("ET") (15:00:00 UTC) on November 10, 2026 and ends at 11:59:59 p.m. ET on November 30, 2026 (04:59:59 UTC on December 1, 2026) (the "Entry Period"). SERI's computer clock is the official timekeeper. This Sweepstakes is separate from every other SERI promotion, and entries do not carry over to any other drawing.

4. How to Enter

(a) There are two ways to enter. Both receive identical treatment, the same prizes and the same chance of winning.

(i) Conference registration. Register for eSummit27 at https://www.electronicssummit.org/register during the Entry Period. Each individual named as an attendee on a registration completed during the Entry Period automatically receives one entry.

(ii) Free entry. Complete and submit the free entry form at https://www.electronicssummit.org/laptop-giveaway during the Entry Period, providing your name, email address, mailing address and state of residence and confirming your age. No registration, purchase or donation is required.

(b) Limit one (1) entry per person for this Sweepstakes, regardless of entry method. Buying more than one registration does not earn additional entries. A person who registered for eSummit before the Entry Period may enter using the free entry form. Duplicate entries will be disregarded, and entries submitted by automated means are void.

(c) Entry does not require agreeing to receive marketing communications.

5. Drawing

On December 3, 2026 at approximately 2:00 p.m. ET (19:00 UTC), by SERI personnel working remotely, SERI will select four (4) potential winners at random from all eligible entries received during the Entry Period, using a documented random number generator, with the entry list and results saved. The odds of winning depend on the number of eligible entries received. The drawing does not depend on any minimum number of entries or registrations.

6. Prizes

(a) Four (4) prizes will be awarded. Each prize is one (1) Lenovo Certified Refurbished ThinkPad T14 Gen 2 (model 20W1X01JR1) laptop computer with an approximate retail value of $799. The total approximate retail value of all prizes in this Sweepstakes is $3,196.

(b) Prize limit: Each person may win only one (1) laptop in total across all SERI eSummit27 Registration Sweepstakes. A person who has already won a laptop in any of those promotions is not eligible to win again, and if selected, an alternate will be drawn.

7. Winner Notification and Prize Award

(a) SERI will notify each potential winner by email within five (5) business days after the drawing. A potential winner must reply within five (5) business days after the notice is sent, confirming eligibility and providing a U.S. shipping address (no P.O. boxes). A potential winner who does not reply in time, is ineligible or does not comply with these Official Rules forfeits the prize, and SERI will select an alternate at random from the remaining eligible entries. SERI will continue selecting alternates until all prizes are awarded.

(b) Lenovo will ship each prize to the verified winner, at Lenovo's expense, within thirty (30) days after verification. Winners do not need to attend eSummit or any other event to receive a prize.

8. General Prize Conditions

(a) Prizes are not transferable and may not be exchanged for cash. If a prize becomes unavailable, SERI may substitute a laptop of equal or greater value. Prizes are provided "as is," subject only to the manufacturer's warranty, if any.

(b) Each winner is responsible for any taxes on the prize, which is generally taxable income at its approximate retail value. SERI will provide any tax reporting required by law.

9. Conduct and Disqualification

SERI may disqualify any person who tampers with the entry process, submits entries by automated means or in violation of the entry limits, or otherwise violates these Official Rules. SERI will not reject entries arbitrarily and will apply these Official Rules equally to every entrant.

10. Limitation of Liability

(a) To the extent permitted by law, SERI and Lenovo are not responsible for lost, late, incomplete or misdirected entries or email, or for technical failures beyond their reasonable control. If a technical failure or fraud prevents the promotion from running as planned, SERI will conduct the drawing from all eligible entries received before the problem occurred and will award all prizes.

(b) By entering, each entrant agrees that, to the extent permitted by law, SERI and Lenovo will not be liable for any loss or injury arising from participation in this promotion or from acceptance or use of a prize. Nothing in these Official Rules limits any right that cannot be waived under applicable law.

11. Privacy and Publicity

(a) SERI will use entrant information to administer this promotion and as described in its privacy policy at https://sustainableelectronics.org/wp-content/uploads/SERI-Privacy-Policy.pdf. Entering does not subscribe an entrant to marketing communications unless the entrant separately chooses to opt in.

(b) SERI may announce the names, cities and states of winners only with each winner's permission, except for any winner list SERI is required by law to provide.

12. Governing Law

These Official Rules are governed by the laws of the District of Columbia, without regard to conflict-of-law rules, except where the law of an entrant's state of residence requires otherwise.
