THE UMBRELLA CORPORATION

Comprised of several subsidiary and affiliate companies, the Umbrella Corporation is the world's largest provider of pharmaceuticals and medical equipment, followed by WilPharma and TriCell, Inc. respectively. Though it's public appearance is fronted by pharmaceuticals, consumer goods, cosmetics, and other household products, it's success is widely dependent on the development and sale of biological and chemical weapons on the black market to any company or nation in the world that can afford them.

They used the original Progenitor virus to create the first B.O.W.s and monopolize the military industry, further weaponizing the T-Virus through covertly conducted illegal and inhuman research and development with the goal of creating increasingly effective virus strains and B.O.W. models. These experiments proved many failures. Despite many biohazard outbreaks over the years, it wouldn't be until the incidents at the facility in the Arklay Mountains, just outside of Raccoon City, that they became more and more difficult to cover up, especially with the added trouble of the Raccoon City Police Department's S.T.A.R.S. team.

Currently, operations are based out of the Raccoon City facility, located miles underground where they are able to not only watch the outbreak originating from the Arklay facility, but develop and test new strains of the viruses.

WILPHARMA

The WilPharma Corporation was the world's second largest phamaceutical company just behind the Umbrella Corporation. With operations overseen by a former Umbrella scientist, WilPharma has found itself in developemnt of a T-Virus vaccine using knowledge not only garnered from his own experience with the corporation, but any virus samples they can purchase or find from within the quarantine of Raccoon City, corporate spies and leaks within the organization, and black market purchases of their wares that have been found on the markets even with the start of the outbreak.

In trials, the vaccined proved successful which earned WilPharma the trust of the government which funded completion of a vaccine, turning a blind eye to the experimentations meant to speed up the development of the vaccine. They kept their clinical trials overseas, where work was cheaper and skilled labor plentiful, from the eyes of the public and, currently, are attempting to keep the growth of third-rank competitor TriCell, Inc. from disrupting their developments while maintaining funding and stock prices among growing concerns from the government about such biological developments, citing Raccoon City as an example.

TRICELL, INC.

TriCell, Inc. is a conglomterate composted of three main divisions -- seaborne shipping, resource development and pharmaceuticals -- initially known at Travis Trading Enterprises. Over the years, it branched into mining operations and discovered many rare metal dig mines, oil fields and natural gas fields, leading to their exploitation and vast profits. They further moved into pharmaceuticals with a primary foothold in Africa, actively collecting animals, plants and insects, utilizing information found in the Natural History Conspectus, written and published by the youngest of seven brothers in the Travis family during the 19th century. When all branches were self-supporting and able to expand, they were split into separate companies under a single parent company, becoming a global company.

With the collapse of the Umbrella Comporation, TriCell was provided with B.O.W. developemnt technology and viruses by way of Albert Wesker whom encouraged them to be used for further B.O.W. product development. TriCell was eventually able to boast the top share of the biological weapon market, selling such to the black market to boost profits as well as fund research on a new marine virus as well as set their sights on competing company WilPharma.
