Dear Greg;

I just wanted to take a moment to more formally thank you for your on-going contributions to MetroNet S.A. de C.V. Our industry (fiber optics and their associated value-added services) is evolving very rapidly here in Mexico, and your expertise and experience has been critical in helping us manage the transition from being a successful start up to a more institutional company.

Since we first began to work together some six months ago, we have worked on a broad range of issues, including: our guiding values and operating principles; our key work tasks and how to structure the organization to most effectively address them; our budgeting processes; and our implementation plans and flow-up, and a profit-driven incentive plan to support all our activities…just to mention a few. Your hands-on, real life, common-sense approach to all the above subjects has made our firm much more productive and profitable. I am particularly pleased by the fact that you have been so effective at communicating effectively at all levels of our company: the fact that you have worked both in Mexico and the United States, in large multinationals as well as mid-sized companies, clearly gives you a lot of credibility with our managers.

As you continue to develop and grow your business, if appropriate, please feel free to us this letter and myself as a strong supporter and reference.

Warmest Regards,

Murray H. Case
Chief Operating Officer
MetroNet, S.A. de C. V.
