ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

FIRST QUARTER - MARCH 31, 1999 COMPARED WITH MARCH 31, 1998

The following discussion and analysis should be read in conjunction with the
financial statements in Part I, Item 1. contained elsewhere in this document.

OVERVIEW

We are organized as a Delaware corporation to engage in the development,
manufacture, distribution, and sale of disinfectants, antiseptics, and
sterilants which are inherently non-toxic, posing no hazard to people who use
them, and which are environmentally friendly, decomposing into harmless,
naturally occurring organic molecules. To this end, the Company has developed
and patented a hard surface disinfectant, VIRAHOL(R), which has been registered
with the Environmental Protection Agency (EPA), and an antiseptic hand gel
sanitizer, made in accordance with the applicable FDA Monograph. The Corporation
has incurred losses since its incorporation. At March 31, 1999, the Corporation
had an accumulated deficit of $27,939,314. The Corporation has financed its
ongoing research program and business activities through a combination of sales,
equity financing, and debt.

RESULT OF OPERATIONS

First Quarter - March 31, 1999 Compared with March 31, 1998

Consolidated gross revenues for first quarter 1999 decreased by $47,872 or 13.6%
to $304,907 compared with $352,779 in first quarter 1998.

-    Gross revenue from product sales decreased for first quarter 1999 by
     $268,988 or 77% to $80,255 compared with $349,243 in first quarter 1998.
     The decrease in sales revenue was primarily due to one major network
     marketing customer, Nutrition For Life, Inc., refocusing their marketing
     efforts to another type of product. A second factor contributing to the
     sales decline was the startup time required for a new dental master
     distributor to create marketing literature and orient their distribution
     channel.

-    Gross revenue from operations/production services (OPS) for first quarter
     1999 was $171,000. OPS revenue is a new source of revenue for the Company
     during first quarter 1999 and is expected to continue at various levels
     throughout 1999. OPS revenue represents quality assurance, research and
     development, purchasing fees and freight-handling fees provided to our
     contract-fill company, which manufactures Veridien's products.

-    Gross rental income for first quarter 1999 increased by 600% to $26,250
     compared with $3,750 in first quarter 1998. A portion of the company's
     leased 38,000 square foot manufacturing facility is subleased to a contract
     filler that manufactures Veridien's products.

-    They relocated to our facility in August 1998. This space is leased for a
     two-year period, which will generate approximately $100,000 per annum.

-    Gross miscellaneous income for first quarter 1999 increased by $27,355 to
     $26,032 compared to $(1,323) in first quarter 1998. Virtually all the
     increase is due to a one-time recognition of gain on the finalization of
     previous year accrued expenses.

-    Interest income for first quarter 1999 increased by $261 or 23.5% to $1,370
     compared with $1,109 in first quarter 1998.

Consolidated gross expenses for first quarter 1999 decreased by $75,507 or 10.3%
to $654,770 compared with $730,277 in first quarter 1998.

-    The cost of goods sold for first quarter 1999 decreased by 56.7% to $76,940
     compared with $177,934 in first quarter 1998. The increase in the cost of
     goods ratio as a percentage of sales was 96% in first quarter 1999 compared
     to 51% in first quarter 1998. The increase in the cost of sales resulted
     primarily from the increased overhead to the contract fill operator
     fulfilling production within the plant facility and the continuing costs of
     fixed overhead applied to lower sales volume.

-    General, selling, and administrative expenses for first quarter 1999
     increased by 21.2% to $459,494 compared with $379,084 in first quarter
     1998. The increases that affected general and administrative costs were
     associated with professional consulting and accounting fees for first
     quarter 1999 that increased by 343% to $195,742 compared with $44,163 in
     first quarter 1998. The increase in professional fees during first quarter
     1999 resulted from the early completion of the consolidated audited
     financials for fiscal year ended 1998, and additional consulting services
     for public relations and public reporting company expenses. During first
     quarter 1999, sales expense decreased by 65% to $38,488 compared with
     $110,881 in first quarter 1998. This decrease was due to the discontinuance
     of a sales consulting contract with a promotional organization.

-    Research and development for first quarter 1999 increased $12,354 or 28.4%
     to $55,818 compared with $43,464 in first quarter 1998. The increase can be
     contributed primarily to increased activity associated with the continuing
     development of Sterihol-Plus, a cold chemical sterilant. Additionally, the
     cost of continuing patent applications has increased.

-    Interest expense for first quarter 1999 decreased by 51.8% to $62,518
     compared with $129,795 in first quarter 1998. The decrease in interest
     expense was due primarily to the conversion of various debts and accrued
     interest to equity.

-    Operating losses decreased to $349,863 first quarter 1999 from $377,498 in
     first quarter 1998. This represented a 7.3% decrease in operating losses.

</TABLE>

Liquidity and Working Capital

Historically, our principal source of financing for our research and development
and business activities has been through sales, equity offerings, and debt. As
of March 31, 1999, and March 31, 1998, we had working capital deficits of
approximately $1,894,010 and $3,697,827, respectively. Our independent certified
public accountants stated in their report on the 1998 consolidated financial
statements that due to losses from operations and a working capital deficit,
there is substantial doubt about the Company's ability to continue as a going
concern. We are addressing the going concern issue in virtually every aspect of
our operation. We have cut operating expenses and have signed two major
distribution agreements, which we expect will provide improved profit margins
beginning in third quarter of 1999. Because of our significant losses incurred
since inception, we have become substantially dependent on loans from officers,
directors, and third parties, and from private placements of our securities to
fund operations. These financings and equity placements are included in the
following descriptions.

-    During first quarter 1999, we received proceeds from the sale of preferred
     and common stock in the amount of $674,878.

-    During first quarter 1999, $93,000 of debt was converted into 1,162,500
     shares of common stock at the conversion rate of $.08 per share.

-    During first quarter 1999, $261,717 of Principal Convertible Debentures and
     $32,033 of accrued interest was converted into 1,958,334 shares of common
     stock at the conversion rate of $.15. The convertible debentures maturing
     on December 31, 1998, were extended to June 30, 2000, and in consideration
     for the extension, the rate was reduced to the lower of the existing
     conversion rate or $.15 to August 31, 1999, thereafter reverting to the
     original conversion price which ranges from $.1851 to $.3868 per share.

-    During the quarter ended March 31, 1999, accounts receivable increased
     $151,699 primarily due to increased obligations of our contract fill
     manufacturer for services provided by our company. Additionally,
     approximately 25% of the increase is due to one customer's delinquent
     account.

-    During the first quarter 1999, inventory increased 55.9% to $144,331
     compared with $92,549 at December 31, 1998. The increase resulted primarily
     from stocking inventory in anticipation of increased sales in 1999.

-    We plan to utilize our current debt financing arrangements and pursue
     additional equity and debt financing while managing cash flow in an effort
     to provide funds to increase revenues to support operation, research and
     development activities. We believe that our long-term success depends on
     revenues from operations from product sales and ongoing royalties from
     technologies. If such sources of funds are not adequate, we may seek to
     obtain financing to meet operating and research expenses from other sources
     including, but not limited to, future equity or debt financings.

-    As of April 1999, we have cash of approximately $129,000 and during May and
     June we expect cash flow of $150,000 from operating activities and private
     placements. This level of liquidity is sufficient to operate the Company
     for 60 days. During the quarter we created new sales planning methodology
     and increased our professional sales staff. The Company anticipates
     increasing sales to begin in the third quarter of 1999, reduced operating
     expenses, and additional private placement funding will contribute to
     continuous operations of the Company.

Year 2000 Compliance

We have analyzed our internal requirements and methods of complying with the
Year 2000 issue concerning computer software and operating equipment utilized in
both R&D functions and general operations. A competent computer software company
has performed a systems analysis and a recommended course of action has been
defined. We find that our accounting computer system is not as yet Year 2000
compliant.

We have developed our reporting criteria and are now selecting, and will
purchase by August 31, 1999, appropriate computer equipment and accounting
software to provide for full Year 2000 compliance and the adequate protection
of company assets and information. We expect the cost of obtaining and
installing new computer equipment and accounting software to be less than
$50,000. We anticipate installing and testing the software during August and
September 1999. We anticipate a short period of time will be necessary to
upgrade and test a to be selected accounting system. In the unlikely event that
we are not successful in implementing our plans for upgrading our accounting
software, we have identified an accounting firm that could produce computerized
financial statements for our company. We anticipate identifying by September
30, 1999, an additional contract fill manufacturer capable of providing
finished product ready for sale to our distributors. We do not anticipate any
material increase in cost of goods by retaining such an additional manufacturer.



                                       10


<PAGE>   11


We find that laboratory systems utilized in R&D and general operations of
equipment are not date sensitive, therefore, the Year 2000 issue is not expected
to require any changes to these existing operations.

We have material relationships with our two contract fill manufacturers who
produce all of our product for distribution. We have begun the process of
discussing their responses concerning their readiness with regards to Year 2000
issues. At this juncture, we have obtained information that leads us to believe
their production equipment is not time/date sensitive and they believe
production can continue as usual. However, they cannot confirm that all of their
raw material suppliers will be in compliance with Year 2000 issues in a timely
manner. The availability of product for distribution is a material issue to our
company. We expect to complete our discovery by July 31, 1999.

If disruptions occur in third party vendors that supply raw materials to our
contract fill manufacturers, we may experience the inability to have product
inventory for sale to our customers. Such events could have material adverse
effect on Veridien to compete effectively in the marketplace. While we believe
our existing contract fill manufacturers will be successful in locating
alternative sources of our commonly available raw materials and converting these
into finished products, we have begun a search for an additional contract fill
manufacturer who can assure us of the timely production of products. We
anticipate having selected such a manufacturer by September 30, 1999.

                                OTHER INFORMATION


ITEM 3.     DEFAULTS UPON SENIOR SECURITIES

On October 5, 1998, Dunvegan Mortgage Corporation sold its interest under the
Loan and Security Agreement. At that time, for the period from June 30, 1997 to
October 5, 1998 the Company owed Dunvegan $286,644 in interest, the payment of
which both parties agreed to defer. On January 28, 1999 the Company's Board of
Directors approved an agreed conversion of a majority of such interest into
Common Stock of the Company at a conversion price of $.14 per share, based on
the then current market price. Issuance of such shares is currently being made,
in the second quarter.
