CORNESTONE'S B2BGALAXY.COM AND TELEFONICA
B2B TO CREATE JOINT VENTURE FOR FOOD
SERVICE ECOMMERCE MARKETPLACE

-  Industry leaders to create new B2B e-Commerce marketplace for the food
services industry in Latin America, Spain and Portugal.

Madrid, 25 July 2000 - Cornerstone Internet Solutions (NASDAQ: CNRS), a provider
of comprehensive business to business (B2B) solutions, and Telefonica B2B, a
leading B2B net market maker, today announced plans to create an electronic
commerce marketplace for the food services industry in Latin America, Spain and
Portugal. This joint venture between Telefonica B2B and Cornerstone's
B2Bgalaxy.com will initially offer a solution for the food services industry in
Spanish and Portuguese speaking markets and could potentially extend to other
industries with similar purchasing needs and behaviours.

'Telefonica B2B will replicate B2Bgalaxy.com's business model in Latin America,
Spain, and Portugal to become the first complete business to business e-Commerce
marketplace for the food services industry in this region', said Miguel Milano,
Chief Operating Officer, Telefonica B2B. 'B2Bgalaxy is yet another step in the
development of Telefonica B2B's diverse portfolio of horizontal and vertical
marketplaces.'

'We are delighted to be partnering with Telefonica B2B - a leading net market
maker - to extend the benefits of our comprehensive B2B solution to Spanish and
Portuguese speaking markets,' said David Rowe, President and CEO of
B2Bgalaxy.com. 'This winning combination will create a dynamic partnership that
should prove beneficial to our clients. B2Bgalaxy.com has already demonstrated
the ability of its PowerProduct applications to cater to a broad array of
domestic clients. This partnership represents the natural evolution of our
PowerProducts from purely domestic solutions to those that can be applied on an
international level.'

Through B2Bgalaxy.com's expanding suite of PowerProducts, including
PowerPurchasing and PowerVendor, food service buyers in Latin America, Spain and
Portugal will be able to purchase supplies online from multiple distributors,
through a virtual private exchange. This exchange enables members to post a
customized inventory list online and requires suppliers to continually submit
their latest product prices. The system produces purchase orders based upon best
price and availability from buyer-selected vendors, driving down the cost of
goods to buyers by as much as 20 percent and significantly reducing the time
traditionally devoted to the comparative price shopping process. In turn, the
platform will increase the efficiency in the distributors' sales process and
will reduce their costs to access buyers by more than 15%.

'This international joint venture further defines our ability to remotely deploy
our marketplaces and technology, while operating these marketplaces for our
partners, either under a licensed deal or ASP model' continued Rowe.
