About BioTime, Inc.

BioTime is a clinical-stage biotechnology company focused on degenerative diseases. Its clinical programs are based on two platform technologies: cell replacement and cell/drug delivery. With its cell replacement platform, BioTime is producing new cells and tissues with its proprietary pluripotent cell technologies. These cells and tissues are developed to replace those that are either rendered dysfunctional or lost due to degenerative diseases or injuries. BioTime's cell/drug delivery programs are based upon its proprietary HyStem® cell and drug delivery hydrogel matrix technology. HyStem® was designed, in part, to provide for the transfer, retention and/or engraftment of cellular replacement therapies. HyStem® is a unique hydrogel that has been shown to support cellular attachment and proliferation in vivo. Current research at leading medical institutions has shown that HyStem® is compatible with a wide variety of cells and tissue types including brain, bone, skin, cartilage, vascular and heart tissues. Due to the unique cross-linking chemistry, HyStem® hydrogels have the ability to mix cells, biologics and small molecule drugs and can be injected or applied as a gel which allows the hydrogel to conform to a cavity or space. This property of HyStem® hydrogels offers several distinct advantages over other hydrogels, including the possibility of combining bioactive materials with the hydrogel at the point of use. BioTime is also developing HyStem® for the delivery of therapeutic drugs and cells to localized areas of the body, including for sustained drug release in the targeted anatomical sites. BioTime's lead cell delivery clinical program is Renevia®, which consists of HyStem® combined with the patient's own adipose (fat) derived tissue or cells. Renevia® met its primary endpoint in an EU pivotal clinical trial for the treatment of facial lipoatrophy in HIV patients in 2017. BioTime has submitted Renevia® for CE Mark approval in the EU. There were no device related serious adverse events reported to date. BioTime's lead cell replacement product candidate is OpRegen®, a retinal pigment epithelium transplant therapy, which is in a Phase I/IIa multicenter clinical trial for the treatment of dry age-related macular degeneration, the leading cause of blindness in the developed world. There have been no unexpected serious adverse events reported to date. BioTime also has significant equity holdings in two publicly traded companies, Asterias Biotherapeutics, Inc. (NYSE American: AST) and OncoCyte Corporation (NYSE American: OCX), and a private company, AgeX Therapeutics, Inc.

BioTime common stock is traded on the NYSE American and TASE under the symbol BTX. For more information, please visit www.biotime.com or connect with the company on Twitter, LinkedIn, Facebook, YouTube, and Google+.

About AgeX Therapeutics

AgeX Therapeutics, Inc., an affiliate of BioTime, Inc. (NYSE American: BTX), is a biotechnology company focused on the development of novel therapeutics for age-related degenerative disease. The company's mission is to apply the proprietary technology platform related to telomerase-mediated cell immortality and regenerative biology to address a broad range of diseases of aging. The current preclinical development efforts include two cell-based therapies derived from telomerase-positive pluripotent stem cells and two product candidates derived from the company's proprietary induced Tissue Regeneration (iTR™) technology. AGEX-BAT1 and AGEX-VASC1 are cell-based approaches in the preclinical stage of development comprised of young regenerative cells modified using the Company's UniverCyte™ technology facilitating immune tolerance, formulated in HyStem® matrix, designed to correct metabolic imbalances in aging and to restore vascular support in ischemic tissues respectively. AGEX-iTR1547 is a drug-based formulation in preclinical development intended to restore regenerative potential in a wide array of aged tissues afflicted with degenerative disease using the company's proprietary iTR technology. Renelon™ is a first-generation iTR product designed to promote scarless tissue repair which the Company plans to initially develop as a topically-administered device for commercial development through a 510(k) application. In addition to the product candidates in early development, the company, through its LifeMap subsidiary, currently markets genomic interpretation algorithms. In addition, the company, through its ESI BIO division, markets Cytiva®, comprised of PSC-derived heart muscle cells used in screening drugs for efficacy and safety.
