Message from President & COO Danny Prosky - Transcript

Hi, I’m Danny Prosky, president and chief operating officer of the Griffin-American Healthcare REITs. I’m also one of the largest stockholders in each of the REITs. I encourage you to join me in casting your votes as soon as possible for the proposals being presented at the companies’ upcoming stockholder meetings. These include proposals which will allow for the merger of these two complementary companies. Whether you own thousands of shares or just a handful, your vote is important to the future of the REITs.

The boards of directors and I urge you to vote in favor of the proxy proposals, which will help create the eleventh largest healthcare REIT in the world and result in significant cost savings of up to 21 million dollars annually. Voting in favor of the merger will also help pave a path to future growth and stockholder liquidity through a potential listing of the merged company on a national stock exchange. It will also help create what we believe will be a far stronger combined company that will generate greater value for you and all of our fellow stockholders.

Voting is quick and easy -- either by mailing back your completed voting card or going to our online voting platform at proxyvote.com and entering your control number. You can also vote by phone. If you’re a Griffin-American Healthcare REIT III stockholder, dial 855-928-4498. For Griffin-American Healthcare REIT IV, call 855-976-3325.

Please vote today and help us build a stronger and better company for all of our stockholders. Thank you for your continued support and your participation.
