      This Agreement is entered into as of January 14, 2005 by and between
VitroTech Corporation, a Nevada corporation ("VitroTech"), Hi-Tech Environmental
Products, LLC, a Nevada limited liability company ("Hi-Tech"), and Enviro
Investment Group, LLC, a Nevada limited liability company ("EIG"), with
reference to the following facts:

      A. Concurrently herewith, VitroTech is entering into a Note and Warrant
Purchase Agreement (the "Purchase Agreement") with Vitrobirth, LLC, a Delaware
limited liability company ("Vitrobirth").

      B. EIG previously agreed (the "Pledge Commitment") to execute a Security
Agreement in favor of 1568931 Ontario Ltd. ("Ontario"), pursuant to which EIG
would grant a security interest to Ontario in Thirty Million (30,000,000) pounds
of mineral (the "Collateral") located on its mine site in Calaveras County,
California.

      C. As of September 30, 2004, VitroTech owed to EIG the sum of $640,931.70,
and VitroTech owed to Hi-Tech the sum of $444,721.88. In addition, Red Rock
Canyon Mineral, LLC ("Red Rock") has an obligation to pay to Mr. and Mrs.
Mathewson the sum of $150,000 plus accrued interest on or before January 30,
2005, and EIG has the obligation to pay Candrea Bennett the sum of $50,000 in
March, 2005.

      D. Effective October 1, 2004, VitroTech, Hi-Tech, EIG and certain other
parties entered into a Settlement and Modification Agreement pursuant to which
Hi-Tech and EIG agreed to forebear from declaring a default under certain
agreements relative to amounts owed to Hi-Tech and EIG, among other things, and
VitroTech agreed to use good faith efforts to allocate a portion of the funds
received from subsequent financings received by VitroTech to reduce the amounts
owing by VitroTech to Hi-Tech and EIG.

      E. As a condition of the financing expected to be received from Vitrobirth
pursuant to the Purchase Agreement, Ontario has agreed to share with Vitrobirth
the collateral pledged by EIG pursuant to the Pledge Commitment and Vitrobirth
has agreed to an allocation of a portion of the financing proceeds being used
for the purpose of reducing the amounts owing to Hi-Tech and EIG, conditioned
upon EIG's signing a Security Agreement covering the Collateral.

      F. Consistent with the undertakings in the Settlement and Modification
Agreement and the Pledge Commitment, EIG is willing to execute and deliver to
Vitrobirth a Security Agreement in recognition of Vitrobirth's consent to use a
portion of the financing proceeds to reduce amounts owed to Hi-Tech and EIG.

      Now therefore, in consideration of the foregoing, and other consideration
actually received, the parties hereto agree as follows:

percent and seven and one-half percent) shall be paid to the remaining obligor.

      3. Except as provided above, nothing herein shall otherwise affect the
obligation to pay EIG and Hi-Tech pursuant to the terms of existing agreements.
