Pursuant to Fed. Rule Civ. Proc. Rule 15(a)(2), Plaintiffs Kimberly Heines, 

Hashmatullah Essar, Paul Dugas, Matthew Ridolfo, Deana Ridolfo, Yaniv Rivlin, Mali 

Granot, Brian Neff, and Andrew J. Mortensen, acting on behalf of themselves and all others 

similarly situated, and Defendants Yahoo! Inc. and Aabaco Small Business, LLC hereby 

stipulate to file the attached Second Amended Consolidated Class Action Complaint. 

1. On January 28, 2019, Judge Lucy Koh issued an Order in this litigation 

denying Plaintiffs’ Motion for Preliminary Approval. ECF 353. In that Order, Judge Koh

noted that the proposed settlement releases claims on behalf of all users in 2012, but the 

operative complaint does not assert claims prior to 2013. Id. at 11. Judge Koh then stated

“any future settlement must amend the FAC.” Id.

2. The attached Second Amended Complaint addresses Judge Koh’s concerns by 

expanding the class definitions to encompass claims arising in 2012 and expanding the 

factual allegations about Yahoo’s security flaws and breaches in 2012. Other than those 

changes, the Second Amended Complaint does not alter the nature of the case or claims 

alleged. 

3. The First Amended Complaint was filed partially under seal in accordance 

with Judge Koh’s Order on Plaintiffs’ Administrative Motion to File Under Seal. ECF 192. 

The Second Amended Complaint preserves, but does not add to, those redactions. A motion 

to file under seal an un-redacted version of the SAC is being filed concurrently herewith. 

4. Defendants Yahoo! Inc. and Aabaco Small Business, LLC filed an Answer to 

the First Amended Complaint on March 23, 2018. ECF 220. To avoid unnecessary repetition, 

that Answer shall be deemed the Answer to the Second Amended Complaint for all purposes.

5. By signing this Stipulation, Defendants Yahoo! Inc. and Aabaco Small 

Business, LLC acknowledge and accept service of the Second Amended Complaint, and 

waive any requirements of further service or challenges to service.
