NOTE 1. BASIS OF PRESENTATION

     The accompanying financial information has been prepared by OCTuS, Inc.
(the "Company") without audit, in accordance with the instructions to Form
10-QSB and, therefore, does not necessarily include all information and
footnotes necessary for a fair presentation of financial position, results of
operations and cash flows in accordance with generally accepted accounting
principles.

     In management's opinion, the accompanying unaudited financial statements
contain all adjustments (which include only normal, recurring adjustments)
necessary to present fairly its financial position at March 31, 1998 and
December 31, 1997, and the results of operations for the three months ended
March 31, 1998 and 1997, and the results of operations for the nine months ended
March 31, 1998 and 1997, and its cash flows for the nine months ended March 31,
1998 and 1997. Although the Company believes that the disclosures made in this
report are adequate to make the information not misleading, these financial
statements should be read in connection with the financial statements and notes
thereto included in the Company's annual report on Form 10-KSB for the year
ended December 31, 1997.

NOTE 3. AGREEMENT FOR DISTRIBUTION OF RETAIL PRODUCT IN NORTH AMERICA

     In March 1995, the Company entered into a three-year agreement with Cintech
Tele-Management Systems, Inc. ("Cintech") granting Cintech exclusive rights to
distribute the retail version of OCTuS PTA in North America. In connection with
the agreement, Cintech also purchased all of the Company's retail OCTuS PTA
inventory and obtained the rights to manufacture additional units of the
product. In March 1997, Cintech elected not to renew its license to distribute
OCTuS PTA.

NOTE 2. EUROPEAN LICENSING AGREEMENT

     On September 5, 1995, the Company entered into a product development and
license agreement with Ascom Telecommunications Limited ("Ascom") of the United
Kingdom. The agreement provides Ascom with an exclusive license to manufacture
and sell to distributors, resellers and end users in Europe a special version of
OCTuS PTA which has been modified to operate through the personal computer's
serial port with Ascom's proprietary telephone. Said exclusivity shall continue
for so long as Ascom sells or otherwise pays OCTuS a specified minimum royalty
on a quarterly basis. The agreement provides that Ascom shall pay the Company a
total of $65,000 for the required modifications to the standard OCTuS PTA
product. To date, the Company has received $60,000 of that amount from Ascom as
payment for the required modifications to the standard OCTuS PTA program. Under
the agreement, Ascom has the right to access the source code of the product in
the event the Company becomes insolvent or is otherwise unable to support the
product. In March 1998, Ascom terminated further development of the OCTuS PTA.

     Net Sales. There were no net sales for the three months ended March 31,
1998, which represented no change, from the same period in 1997. This lack of
sales is primarily the result of the completion of the Company's shift, begun in
1995, from selling its OCTuS PTA product through retail channels to one of
promoting its technology through licensing.

     Royalties. There was $10,000 royalty income recorded for the three months
ended March 31, 1998, which represented a change of $10,000 or 100%, from the
same period in 1997. Such amount for the current period ended March 31, 1998
represents royalty income received from Ascom Telecommunications Limited of the
United Kingdom ("Ascom"), which in September 1995, executed a license agreement
with the Company whereby the Company granted exclusive rights to Ascom to
manufacture and distribute a special serial-port version of the OCTuS PTA
software to the European market.

     Cost of Sales. The Company recorded $10,000 for cost of sales for the three
months ended March 31, 1998; an increase of $10,000 from the $0 recorded from
the same period in 1997. The increase reflects the completion of the transition
of the Company from a sales and marketing company to a licensing organization,
as the cost of sales was associated with the upgrading of the OCTuS technology
to conform to requirements set by the Company's licensee Ascom. This reflects an
increase in royalty income as compared to the same period in the previous year,
which was due to completion of the Company's transition from its focus on sales
and marketing to one of licensing of its technology.

     Selling, General and Administrative. The Company recorded $43,000 for
selling, general and administrative expenses for the three months ended March
31, 1998, a decrease of $11,000, or 20.0 %, from the same period in 1997. This
decrease from the prior period is due primarily to the continued downsizing of
the Company and the shift from a sales organization to a licensing organization.

     Net Loss. Net loss for the three months ended March 31, 1998 was $44,000,
as compared to a $55,000 loss for the same period in 1997.



                                       8

     LIQUIDITY AND CAPITAL RESOURCES.

     For the three months ended March 31, 1998, the Company posted a net loss of
$44,000. The Company's operating and investing activities used cash of $60,000.
Cash on hand on March 31, 1998 was $1,500. For the year ended December 31, 1997
the Company incurred a net loss of $219,101. In March 1997, Cintech elected not
to renew its license to distribute OCTuS PTA. In March 1998, Ascom terminated
further development of the OCTuS PTA program. Management believes that without
an influx of significant new revenues from the licensing of the Company's
products, the Company's cash on hand and revenues from operations will not be
sufficient to sustain its operations through the rest of 1998. Although the
Company has actively been pursuing such licensing arrangements and new
investment, there can be no assurance that any licensing agreements and/or new
investment will be entered into by the Company, or that the terms of any such
agreements will be on terms favorable to the Company. In June 1996, the Company
sold to Advanced Technologies International, Ltd. ("ATI") 250,000 shares of
Series C Preferred stock (which votes with the Common Stock with each share of
Series C Preferred Stock having ten votes) for $151,000 and issued warrants to
purchase up to an additional 3,000,000 shares of the Company's Common Stock at
an initial exercise price of $0.43 per share. The Company currently has been
meeting its additional liquidity needs through loans from ATI. The loan balance,
$371,443 as of March 31, 1998, has been increasing at approximately $15,000 per
month. The Company pays 10.0% simple interest on such loans and the loan is due
within five (5) days of the Company's receiving sufficient funds from the
exercise of warrants by ATI. Although ATI has advanced funds, on a monthly
basis, to the Company to meet its current cash requirements, there is no
commitment from ATI to continue these advances. Should the Company be unable to
obtain additional revenues and/or raise additional capital, it could be forced
to cease business activities altogether.


                  RISK FACTORS WHICH MAY AFFECT FUTURE RESULTS

     HISTORY OF OPERATING LOSSES

     For the calendar year ended December 31, 1997, the Company recorded a loss
of $219,101. For the calendar year ended December 31 1996, the Company recorded
a loss of $191,056.

     At March 31, 1998, the Company had no tangible assets, no working capital,
an accumulated deficit of $22,522,505 and a shareholder' deficit of $404,929.
With both the Cintech and the Ascom transactions terminated, and due to the
absence of a significant level of sales of the Company's products, either as
stand-alone retail units or incorporated into third party products, the Company
will continue to generate significant losses. It is unlikely that the Company's
existing operations will be successful or will be profitable in the future.


     NEED FOR ADDITIONAL CAPITAL

     The Company's cash on hand as of March 31, 1998 was $1,500, which is
inadequate to meet the Company's budgeted operating requirements. Additional
cash resources are required to sustain the Company's operations unless adequate
revenues from sales and licensing of the Company's OCTuS PTA product line
develop, of which there can be no assurance. While operations to date are being
funded by loans from ATI, one of the Company's principal shareholders, it should
be noted that the Company has no commitment from any party to provide additional
capital and there is no assurance that such funding will be available when
needed or, if available, that its terms will be favorable or acceptable to the
Company. Should the Company be unable to obtain additional capital when and as
needed, it could be forced to cease business activities altogether. It is
unlikely that the Company will be able to raise additional capital without
dramatically diluting the existing equity ownership of the Company's Common
stockholders.


     RESTRUCTURING OF OPERATIONS

     The Company underwent substantial restructuring in 1994 and 1995, primarily
as a result of continued operating losses. This restructuring included a
substantial reduction in the Company's workforce from 46 employees (as of March
31, 1994) to one employee (as of July 1, 1997) as well as relocation of its
headquarters to another facility with lower operating costs. In addition, Ray



                                       9
<PAGE>   10
M. Healy became the Company's President and Chief Executive Officer in November
1994. However, Mr. Healy resigned as the Company's President and Chief Executive
Officer on May 31, 1995 in order to pursue other opportunities and Mr. Belden
was re-appointed to that position. Mr. Belden is the sole remaining executive
officer of the Company. Mr. Donald O. Aldridge, a director of the Company since
June 1995, was appointed Chairman of the Board of the Company in October 1995.
In June 1996, the Company sold to ATI 250,000 shares of Series C Preferred Stock
(which votes with the Company's Common Stock with each share of Series C
Preferred Stock having ten votes) for $151,000 and issued warrants to purchase
up to an additional 3,000,000 shares of the Company's Common Stock at an
exercise price according to the following schedule: $0.43 per share for the
first 1,000,000 shares, $0.50 per share for the second 1,000,000 shares, and
$0.75 per share for the final 1,000,000 shares.

     Although this restructuring effected a major reduction in the Company's
operating expenses, the Company's cash on hand continues to be insufficient to
meet its present operating expenses. Without a substantial increase in revenues,
which is unlikely, the Company will be required to cease its business operations
altogether.


     NEED FOR PRODUCT ACCEPTANCE

     The Company's ability to complete the development and testing of future
revisions and/or improvements to OCTuS PTA is uncertain due to lack of
sufficient financial resources. As such, there is no assurance that the
Company's testing and development schedules for such future versions will ever
be met. The Company's inability to complete such development and testing could
have a material adverse effect on the Company's financial condition and results
of operations, and could raise questions as to the Company's ability to continue
as a going concern.

     In addition, because the computer industry is characterized by rapid
technological change, there can be no assurance that the Company's products will
not be rendered obsolete as a result of technological developments before or
after their introduction. The Company's limited resources has impaired the
Company's ability to quickly introduce its new products, continually improve
such products and develop other products in order to compete effectively in this
industry. Accordingly, it is unlikely that the Company will be able to complete
the development of such new products or improvements on a timely basis, if at
all.

     MARKETING/DEPENDENCE ON OTHERS FOR DISTRIBUTION

     In order to generate significant revenues from OCTuS PTA, the Company must
successfully implement a program to license the product to companies in the
personal computer and telecommunications industry for incorporation into their
respective products. Due to the limited funds available to the Company, it is
unlikely that the Company will be able to succeed in such a program.


     DEPENDENCE ON THIRD PARTY SOFTWARE

     The Company's products are designed for use with Microsoft(R) Windows(TM).
Although the product functions with Windows 95, the Company will likely have to
revise its product for use with newer versions of that product as well as for
each different combination of computers and telephone systems. In addition,
since the Company's products operate in conjunction with these other operating
systems and applications, changes to such systems will require the Company to
adapt its products accordingly. The Company's ability to perform such ongoing
development has been impaired by its present financial condition and it is
unlikely that the Company will be capable of conducting any such improvements,
which could affect the Company's ability to continue as a going concern.
Further, the rapid pace of hardware platform advances and the inability of the
Company to update the OCTuS PTA software to meet such new hardware standards
significantly hinder the software's compatibility with new computers sold today.
It is therefore unlikely that the Company will be able to upgrade the OCTuS PTA
software to insure compatibility with today's and future computing platforms.

     HIGHLY COMPETITIVE INDUSTRY

     The computer industry is highly competitive and rapidly changing. There are
other companies that are engaged in marketing and development of products
similar to certain of the Company's products that employ similar technologies
which directly compete or could compete with the remainder of the Company's
products. Many of these competitors have significantly greater financial,
technical, manufacturing, and marketing resources and greater name recognition
than the Company. The Company believes that due



                                       10
<PAGE>   11
to the nonproprietary nature of its products and the relatively low barriers to
entry to its markets that, unless it establishes a significant installed base
before its competitors, the Company will not have any sustainable long-term
advantage over its competitors. The Company believes that its ability to compete
depends on elements both within and outside its control, including the success
and timing of new product development by the Company and its competitors,
product performance and price, productivity enhancement, distribution and
customer support. Given its limited resources, it is unlikely that the Company
will be able to compete successfully with respect to these factors or others.

     FLUCTUATIONS IN OPERATING RESULTS

     The Company's operating results may vary significantly from period to
period depending on factors such as the timing of new product introductions by
the Company and its competitors, product mix, changes in distribution channels,
increased competition, changes in product demand resulting from seasonal
fluctuations in business activity, and changes in operating and material costs.
As a result of these and other factors, the Company could experience significant
fluctuations in results of operations in future periods.

     INTELLECTUAL PROPERTY

     The Company generally relies on confidentiality agreements with its
employees and consultants to protect its proprietary information. There is no
assurance that existing or future patents, copyrights, trademarks and
confidentiality agreements will afford protection from material infringement.
There is also no assurance that the Company's technologies and products will not
infringe upon patents or copyrights of others. Management of the Company
believes that because of the rapid pace of technological change in its industry,
patent and copyright protection is less significant than the ability of the
Company to develop and market new products.

     GENERAL ECONOMIC AND MARKET CONDITIONS

     Demand for the Company's products depends largely upon the overall demand
for computer and communications products. Demand for such products fluctuates
from time to time based on numerous factors, including capital spending levels
and general economic conditions. There is no assurance that there will not be a
decline in overall demand for computer and communications products as a result
of general economic conditions or otherwise, and any such decline could have a
material adverse effect on the Company's business.



     TRANSACTIONS WITH AFFILIATES

     The Company has been a party to certain transactions with related persons
and affiliates. The Company believes that all such transactions were in its best
interests and on terms no less favorable to the Company than could have been
obtained from unaffiliated third parties and each transaction was approved by
disinterested and independent members of the Board of Directors. However, such
agreements were not always reached as the result of arms-length negotiations. In
June 1996, the Company sold to ATI 250,000 shares of Series C Preferred stock
(which votes with the Common Stock with each share of Series C Preferred Stock
having ten votes) for $151,000 and issued warrants to purchase up to an
additional 3,000,000 shares of the Company's Common Stock at an initial exercise
price of $0.43 per share. The Company currently has been meeting its additional
liquidity needs through loans from ATI. The loan balance, $261,811 as of
December 31, 1997, has been increasing at approximately $15,000 per month. The
Company pays 10.0% simple interest on such loans and the loan is due within five
(5) days of the Company's receiving sufficient funds from the exercise of
warrants by ATI. The loans are month to month loans and the continued operations
of the Company are wholly dependent on such loans from ATI. There is no
assurance that ATI will continue to fund Company or that ATI will exercise its
warrants to enable Company to repay such loans to ATI. Should the Company be
unable to obtain additional revenues, which is unlikely, and/or raise additional
capital, it could be forced to cease business activities altogether.



     NOTES AND ADVANCES PAYABLE

     On December 1, 1995, Maroon Bells Capital Partners, Inc. (Note 4) advanced
$25,000 to the Company for working capital purposes. The note bears interest at
8% and was due with accrued interest on November 30, 1997. Additionally, the
note may be

converted at any time into shares of the Company's Common Stock at the rate of
$.25 per share. The note also contains certain acceleration and anti-dilution
clauses upon conversion. Maroon Bells was also granted 25,000 warrants with a
nominal fair market value, to purchase the Company's Common Stock at a price per
share of $.25. The warrants are for a five-year period. The note was paid in
full on March 3, 1998.

     The Company currently has been meeting its additional liquidity needs
through loans from ATI. The loan balance, $371,443 as of March 31, 1998, has
been increasing at approximately $15,000 per month. The Company pays 10.0%
simple interest on such loans and the loan is due within five (5) days of the
Company's receiving sufficient funds from the exercise of warrants by ATI. The
loans are month to month loans and the continued operations of the Company are
wholly dependent on such loans from ATI. There is no assurance that ATI will
continue to fund Company or that ATI will exercise its warrants to enable
Company to repay such loans to ATI.

     TRADING MARKET/DELISTING FROM NASDAQ SMALLCAP MARKET/VOLATILITY OF STOCK
     PRICE

     In January 1993, the Company completed an initial public offering of
2,000,000 Units, each unit comprised of one share of Common Stock and one Common
Stock Purchase Warrant. These securities were quoted on the Nasdaq SmallCap
Market until February 1, 1995, at which time they were delisted due to the
Company's inability to meet that market's minimum capital and surplus
requirements. The securities now trade on the OTC Bulletin Board (commonly
referred to as the "pink sheets"), maintained by the National Quotation Bureau,
Inc., which are generally considered to be less efficient markets. While the
Company intends to reapply for listing on the Nasdaq SmallCap Market if
conditions are favorable for it to do so, there can be no assurance that the
Company's securities will be accepted by the Nasdaq SmallCap Market upon
application by the Company for relisting.

     The market price of the Common Stock, Units, and Warrants, like that of the
securities of many other high technology companies, has been highly volatile.
Factors such as fluctuation in the Company's operating results, announcements of
technological innovations or new products by the Company or its competitors,
developments in the Company's strategic alliances with other companies, and
general market conditions may have a significant effect on the market price of
the Common Stock. See table in Part II, Item 5, "Market for Common Equity and
Related Stockholder Matters."


     SHARES ELIGIBLE FOR FUTURE SALE

     Sales of substantial amounts of the Common Stock in the public market could
have an adverse effect on the price of the publicly-traded Common Stock could
potentially adversely affect the Company's ability to raise additional funds. At
December 31, 1996, 189,799 stock options held by Mr. Belden at the time of the
January 1993 initial public offering, are subject to a lockup agreement with RAS
Securities Corp., the underwriter of the initial public offering, whereby such
persons have agreed not to sell, contract to sell, or otherwise dispose of such
shares of Common Stock, without the consent of RAS Securities Corp., until the
date the Company has $1.0 million or more in earnings after taxes in any fiscal
year as certified by the Company's independent accountants.


     EFFECT OF CERTAIN ANTI-TAKEOVER CHARTER AND BYLAW PROVISIONS

     Certain provisions of the Company's Amended and Restated Articles of
Incorporation (the "Articles") and Bylaws could have the effect of making it
more difficult for a third party to acquire, or could discourage a third party
from attempting to acquire, control of the Company. Such provisions may limit or
reduce the price that investors might be willing to pay for shares of the Common
Stock. Certain of such provisions allow the Company to issue preferred stock
with rights senior to those of the Common Stock and impose various procedural
and other requirements that could make it more difficult for shareholders to
effect certain corporate actions. The Articles also provide for a classified
board in the event the Company's shares are traded on a national securities
exchange or the Nasdaq National Market. A classified board could make it more
difficult for a third party to acquire control, or could discourage a third
party from attempting to acquire, control of the board.

ITEM 3. DESCRIPTION OF PROPERTY.

     In October, 1996, the Company moved its offices to a 400 square foot office
suite in an area of northern San Diego known as the "Golden Triangle". The new
facility is approximately eight miles north of the Company's former site in
Kearny Mesa. The Company occupies this space on a month-to-month basis for
approximately $100 per month.

     The Company does not maintain any other leases for office space and owns no
real property.

     None.

ITEM 5. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
