To the Board of Directors
Quadratech, Inc.
Monrovia, California


I have compiled the accompanying consolidated balance sheets of Quadratech, Inc.
(a Nevada corporation) and its wholly-owned subsidiary, Oil Scavenger Absorbent,
Inc.(a California corporation), as of March 31, 1998 and 1997, and the related
consolidated statements of operations and accumulated deficit, and cash flows
for the three months then ended, in accordance with Statements on Standards for
Accounting and Review Services issued by the American Institute of Certified
Public Accountants.

A compilation is limited to presenting in the form of financial statements
information that is the representation of management. I have not audited or
reviewed the accompanying financial statements and, accordingly, do not express
an opinion or any other form of assurance on them.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in the Note 9 to
the consolidated financial statements, the Company's significant operating
losses, working capital deficiency and deficit in stockholders' equity raise
substantial doubt about their abilities to continue as a going concern. The
consolidated financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

neither for 1998 nor 1997.

II.  Management's Discussion and Analysis or Plan of Operation

Results of Operation.

     For the current quarter, the Company has continued to focus on marketing
its oil absorbent products.

     The Company has continued to maintain its reduced selling, general and
administrative costs decreased substantially as a result of a reduction in
personnel and decreased marketing costs associated with the sale of products to
its customers.

Liquidity and  Capital Resources.

     The liquidity of the Company and its available capital resources have not
improved.

     The Company believes that internally generated funds and the sale and
issuance of stock for cash or in cancellation of indebtedness may provide
minimum capital resources to finance operations and fund capital expenditures.
The Company's need for funds has been reduced predicated upon the significant
reduction in property rental and maintenance expenses and the reduction of
marketing costs and research activities.

     For the current quarter, the Company had no material commitments to acquire
additional assets.
