SYMETRYX RECOMMENDS VOTING AGAINST THE KEYSTONE DENTAL MERGER

SYMETRYX RECOMMENDS VOTING FOR THEIR QUALIFIED INDEPENDENT BOARD NOMINEES

TIME IS SHORT - THE VOTE DEADLINE IS 11:59 pm EST THURSDAY DECEMBER 14^th 2023 - SHAREHOLDERS MAY VOTE OR CHANGE A PREVIOUSLY CAST VOTE UNTIL THAT TIME

TORONTO, Dec. 13, 2023 /PRNewswire/ - Further to its news release of November 28, 2023, Symetryx continues to urge its fellow Check-Cap Ltd. ("Check-Cap") (NASDAQ: CHEK) shareholders to VOTE AGAINST the Keystone Dental and FOR the Symetryx slate of highly qualified and independent director nominees. See Symetryx Today Issues Open Letter to Shareholders In Regard to the Upcoming Annual General Meeting (newswire.ca)

On December 12^th 2023, a Court Hearing was held in the Haifa Israel Economic District Court in regards to Symetryx claim on Check-Cap solicitation wrongful methods for the upcoming annual general meeting, scheduled to December 18, 2023. During this hearing, a potential conflict of interest between Uri Geiger, the Chairman of Keystone Dental, and Yuval Yanai, a Check-Cap director was revealed during Mr. Yanai's testimony, when he confessed that Mr. Geiger offered him a seat at the new board of directors following the closing of the merger.

Based on public records, Mr. Yanai and Mr. Geiger were both board members of Minerva Surgical, Inc., a company that develops medical devices. Uri Geiger is also the managing partner of Accelmed, a venture capital firm that invests in medical device companies, including Minerva Surgical and Keystone Dental. Yuval Yanai is also the chairman of the board of directors of Exalenz Bioscience. Uri Geiger was the CEO of Exalenz Bioscience until 2019.

This potential conflict of interest raises serious concerns about the approval process of the Keystone-Check-Cap merger, and strengthen Symetryx's assumptions regarding the merger not being in the best interest of all Check Cap's shareholders.

Furthermore, the U.S. FDA MAUDE database (Manufacturer and User Facility Device Experience), which is publicly accessible and identifies action taken by the FDA against companies, has received over 500 complaints in 2023 alone, reporting medical defects and deficiencies with various Keystone Dental appliances, including loss of osteo-integration and adverse reactions and failures by patients. See the FDA website: MAUDE - Manufacturer and User Facility Device Experience (fda.gov) and enter Keystone Dental in the search tab. This action by the FDA could potentially harm Keystone's business, financial condition and results of operations and, as a result, negatively impact your investment.

Symetryx is pleased to see that other stakeholders agree that the transaction with Keystone Dental DOES NOT provide the maximum value for shareholders. We once again urge all shareholders to reject the Keystone transaction by voting AGAINST Proposal #1, the Keystone transaction, and to support the Symetryx Board nominees by voting FOR each. Only with a new, independent Board do we believe, that we shareholders will have the best opportunity to realize the full value of our investment and not give it away to Keystone's investors.

Symetryx has engaged Mackenzie Partners, Inc. to act as an advisor in this matter, we welcome shareholders to reach out to share their views or should they seek clarification on our own. Mackenzie Partners can be reached at 1-800-322-2885 or bmarese@mackenziepartners.com

Sincerely,

Symetryx Corporation
