                           FORWARD-LOOKING STATEMENTS

         This Report contains certain statements of a forward-looking nature
relating to future events or future financial performance of Oncor, Inc.
(hereafter referred to as "Oncor" or the "Company"). Readers are cautioned that
such statements are only predictions and that actual events or results may
differ materially. In evaluating such statements, readers should specifically
consider the various factors identified in this Report and in the Company's
other public filings which could cause actual results to differ materially from
those indicated by such forward-looking statements, including the matters set
forth in the various captions under "Item 1. Business" and "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations." The
Company undertakes no obligation to publicly update or revise any
forward-looking statements, whether because of new information, future events or
otherwise.


                                     PART I

ITEM 1. BUSINESS

IMPORTANT 1999 DEVELOPMENTS

Sale of assets

         On February 10, 1999, the Company sold its 80% interest in Appligene
Oncore ("Appligene"), a French company, to a Canadian company for $1 million.
(See Note 3 to the consolidated financial statements for additional information
on this transaction.)

         After the sale of Appligene and the several transactions described
under the caption "Business" below, the Company's only remaining assets
consisted of certain Oncor and Codon intellectual property and licenses. The
future uses, if any, of these remaining assets are being explored by the
Company. The Company currently has no revenues from operations.

Chapter 11 Filing

         On February 26, 1999 (the "Petition Date"), Oncor, Inc. and its
wholly-owned subsidiary, Codon Pharmaceuticals, Inc. (the "Debtor"), filed
voluntary petitions for relief under Chapter 11 of the United States Code (the
"Bankruptcy Code") with the United States Bankruptcy Court for the District of
Delaware, Wilmington, Delaware. Under Chapter 11, certain claims against the
Debtor in existence before the filing of the petitions for relief under the
Bankruptcy Code are stayed while the Debtor continues as debtor-in-possession.

         Pursuant to the provisions of the Bankruptcy Code, all actions to
collect upon any of the Company's liabilities as of the Petition Date or to
enforce pre-Petition contractual obligations were automatically stayed. Absent
approval from the Bankruptcy Court, the Company is prohibited from paying
pre-Petition obligations. However, the Bankruptcy Court has approved payment of
certain pre-Petition liabilities as of the Petition Date such as employee wages
and benefits and certain specified pre-Petition obligations. Additionally, the
Bankruptcy Court has allowed for the retention of legal and financial
professionals and other payments to protect the holders of claims against the
Company. As a debtor-in-possession, the Company has the right, subject to
Bankruptcy Court approval and certain other conditions, to assume or reject any
pre-Petition executory contracts and unexpired leases. Parties

                                        2

<PAGE>

affected by such rejections may file pre-Petition claims with the Bankruptcy
Court in accordance with Bankruptcy procedures.

         Oncor expects to reorganize under Chapter 11 and to propose a
reorganization plan or plans. At this time, it is not possible to predict that
any Plan filed will be approved or confirmed by the Bankruptcy Court, or that
such plans will be consummated. If a plan is not approved, the Company may be
required to liquidate.

         Reference is made to Item 7 "Management's Discussion and Analysis of
Results of Operations and Financial Condition" and the Report of Independent
Public Accountants included in Item 8 - "Consolidated Financial Statements and
Supplementary Data" which indicate the substantial doubt about Oncor's ability
to continue as a going concern.

THE COMPANY

         Oncor, Inc. along with its consolidated subsidiaries was incorporated
in Maryland in July 1983. Oncor's principal offices are located at 209 Perry
Parkway, Gaithersburg, Maryland 20877, and its telephone number is (301) 963-
3500.

BUSINESS

         During 1998, as part of the Company's plan to reduce its scope of
operations and ongoing operating expenses, the Company disposed of a significant
portion of its business and the related assets. (See Note 3 to the consolidated
financial statements under Item 8 for additional information on the following
transactions.)

         Effective February 28, 1998, the Company acquired all remaining
outstanding shares of Codon Pharmaceuticals, Inc. ("Codon"). On October 1,
1998, Codon ceased all operations.

         On April 9, 1998, the Company completed a transaction with Vysis, Inc.
in which Oncor conveyed to Vysis for $0.5 million in cash and full rights and
title to its non-oncology genetics probe assets ("Genetics Assets"), including
primarily inventories and intellectual property, in exchange for two licenses to
patents owned or licensed to Vysis. (These two licenses were surrendered in the
November 24, 1998 transaction discussed below.) In addition, the parties agreed
to settle all legal action between them with respect to a suit brought by Vysis
against the Company in September 1995.

         On June 30, 1998, the Company completed the sale of its Research
Products Assets, including primarily inventory, laboratory equipment and
intellectual property, to Intergen Company for cash consideration of $3.1
million.

         On September 28, 1998, pursuant to a plan of merger between Oncormed,
Inc. and Gene Logic, Inc., the Company exchanged 900,000 shares representing all
its shares in Oncormed for approximately 420,000 shares of Gene Logic, Inc.
common stock.

         On November 23, 1998, the Company voluntarily surrendered assets
related to its in situ Hybridization business to certain of the Company's
secured creditors. The creditors simultaneously sold these assets to Ventana,
Medical Systems. The proceeds were used to liquidate the debt due the secured
creditors and to pay other obligations of the Company.

FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS AND FOREIGN AND DOMESTIC
OPERATIONS AND EXPORT SALES

         See Note 8 to the consolidated financial statements under Item 8 of
this Report for industry segment and foreign and domestic operations and export
sales information.

YEAR 2000 COMPLIANCE

         After the Company's disposition of substantially all of its remaining
assets and operations, the Company does not believe it has any material exposure
to Year 2000 relating to its computer systems or those systems on which the
Company depends.

ADDITIONAL RISK FACTORS

         As discussed above, the Company's only remaining assets consisted of
certain Oncor and Codon intellectual property and licenses. The future uses, if
any, of these licenses are being explored by the Company. The Company currently
has no revenues from operations. In addition, the Company has filed voluntary
petitions for relief under the Bankruptcy Code. If the Company continues in
operation in any manner it will be subject to significant additional risks,
including the risks summarized below.

         History of Operating Losses

         ONCOR HAS NOT BEEN PROFITABLE SINCE ITS INCEPTION IN JULY 1983. AS
INDICATED ABOVE, THE COMPANY HAS DISPOSED OF A SIGNIFICANT PORTION OF ITS ASSETS
AND OPERATIONS AND CURRENTLY HAS NO REVENUES FROM OPERATIONS.

         Additional Financing Requirements and Access to Capital Funding

         IF THE COMPANY CONTINUES IN OPERATION IN ANY MANNER, IT WILL BE SUBJECT
TO RISKS ASSOCIATED WITH ADDITIONAL FINANCING REQUIREMENTS AND ACCESS TO CAPITAL
FUNDING. THE COMPANY'S CURRENT LIQUID RESOURCES ARE NOT SUFFICIENT TO SATISFY
ITS CURRENT OBLIGATIONS.

         Trading in Company's Common Stock

         In October 1998, the Company was delisted from the American Stock
Exchange. It now trades on the Over-the-Counter Bulletin Board. This market will
likely provide substantially less liquidity and market support for the
stockholders of the Company and materially and adversely affect the ability, if
any, of the Company to raise additional equity for any future business
operations. Additionally, the bankruptcy proceedings may have an adverse effect
on the trading in the Company's stock. There is no assurance that the Company's
stock will continue to be traded even on the Bulletin Board.

         Requested Redemption of Series A Convertible Preferred Stock

         The Company is subject to risks associated with the requested
redemption of Series A convertible preferred stock (the "preferred stock"). (See
Note 6 to the consolidated financial statements relating to the issuance of this
preferred stock.) On August 7, 1998 and August 11, 1998, the Company received
requests from the holders of the preferred stock, which had an aggregate
original issuance amount equal to $5 million and a higher redemption amount, to
have their shares of preferred stock redeemed. The Company believes that there
are certain legal and financial impediments to the satisfaction of these

                                        4

<PAGE>



requests, even if determined to be valid. If such redemption request is
ultimately held to be valid, the Company does not have, and probably cannot
obtain, the funds necessary to redeem the preferred stock (See Note 6 to the
consolidated financial statements for additional information).

         No Assurance of Regulatory Approvals, Government Regulation

         As indicated above, the Company's only remaining assets consist of
certain Oncor and Codon licenses. The future uses of these licenses are being
explored by the Company. If a use of these licenses is found, there is no
assurance that the Company will receive regulatory approval or clearance for the
use of any products developed using these licenses, if required, or have the
financial ability to pursue approval or clearance.

         Patents and Proprietary Rights

         The use of the above-mentioned licenses also depend in a large part on
the Company's ability to obtain patents, where needed, defend the patents,
maintain trade secrets and operate without infringing upon the propriety rights
of others. The patent position of firms relying upon biotechnology is highly
uncertain in general and involves complex legal and factual questions. There is
no assurance that patents issued are sufficiently broad enough to afford
protection against competitors with similar technology. In addition, there can
be no assurance that any patents issued to the Company, or for which the Company
has license rights, will not be challenged, invalidated or circumvented, or that
the rights granted thereunder will provide competitive advantages to the
Company. Litigation relative to patents, licenses or any rights could result in
litigation. The Company currently does not have the financial ability to defend
any such litigation.

         Uncertainties Relating to Product Development

         If, in the future, the Company seeks to develop one or more products,
it will be subject to risks associated with uncertainties relating to product
development. There can be no assurance that the Company or any future
development partner will be successful in developing existing or future
products, that such products will prove to be efficacious in clinical trials,
that required regulatory approvals or clearances can be obtained for such
products, that such products, if developed and approved, can be manufactured in
commercial quantities at reasonable costs, will be marketed successfully or will
be accepted by the medical diagnostic community, or that market demand for such
products will be sufficient to allow profitable operations.

         Competition and Technological Change

         If the Company were to continue in operations, it will be subject to
the risks associated with competition and technological change. The diagnostic
and biotechnology industries are subject to intense competition and rapid and
significant technological change. Competitors in the United States and foreign
countries are numerous and include, among others, diagnostic, health care,
pharmaceutical, biotechnology and chemical companies, academic institutions,
government agencies and other public and private research organizations. Many of
these competitors have substantially greater financial and technical resources
and production and marketing capabilities than the Company. There can be no
assurance that these competitors will not succeed in developing technologies and
products that are more effective, easier to use or less expensive than those
that have been or would be developed by the Company or that would render the
Company's technology and products obsolete and

                                        5

<PAGE>



noncompetitive. The Company would also have to compete with various companies in
acquiring technology from academic institutions, government agencies and
research organizations. In addition, many of the Company's competitors have
significantly greater experience than the Company in conducting clinical trials
of new diagnostic products and in obtaining FDA and other regulatory approvals
of products for use in health care. Accordingly, the Company's competitors may
succeed in obtaining regulatory approval for products more rapidly than the
Company.

         Attraction and Retention of Key Personnel

         If the Company were to continue operations, it will be subject to risks
associated with attracting and retaining key personnel to replace those who have
resigned or have been terminated. Competition for such personnel and advisors is
intense, and the Company's ability to attract and retain such personnel will be
adversely affected by the current financial condition of the Company; therefore,
there can be no assurance that the Company could attract and retain such
personnel.

         Product Liability

         If the Company were to continue operations, it will be subject to risks
associated with product liability. The testing, marketing and sale of health
care products could expose the Company to the risk of product liability claims.
Presently, the Company does not have the resources to defend or settle any
uninsured product liability claims that may be filed against it.

         While the Company maintains product liability insurance coverage of $5
million per occurrence, there can be no assurance, however, that such insurance
policy will respond to any specific claim, that this coverage will be adequate
to protect the Company against future product liability claims or that product
liability insurance will be available to the Company in the future on acceptable
terms, if at all.

EMPLOYEES

         The Company currently has 3 employees (2 clerical and 1 Research and
Development). The Company's acting President and Chief Operating Officer serves
on a consulting basis. The Company also retains the services of a full time
accountant on a temporary basis and an accountant on a consulting basis, as
needed. All other employees of the Company have resigned or been terminated.


ITEM 2. PROPERTIES

         The Company currently leases facilities in Gaithersburg, Maryland

ITEM 3. LEGAL PROCEEDINGS

         The Company has received notices from time to time claiming that
certain of the Company's products infringe patents of third parties and has
submitted the notices to its patent counsel for review. There can be no
assurance, however, that these claims will not lead to infringement proceedings
involving the Company or that the Company would prevail in any such proceedings.
Patent litigation has frequently proven in recent years to be complex and
expensive and the outcome of patent litigation can be difficult to predict. In
the Company's present financial condition, it probably could not litigate any
litigation filed or to pay damages if proven.

         On April 27, 1998, the Company received a summons and complaint in
connection with a lawsuit entitled Key Technology, Inc. V. Oncor, Inc. in the
Superior Court of the State of Washington for the County of Walla Walla. The
complaint alleges breach of contract and fraud concerning a June 1996 asset
purchase agreement between Key Technology relating to the sale of the Company's
1300 video inspection systems to Key Technology, and seeks damages against the
Company of $1,475,000. A failure to successfully defend against or settle that
suit would likely result in damages being assessed against the Company.
Management currently cannot estimate what liability, if any, could result from
this dispute.

         During 1998, two entities who entered into a partnership agreement with
the Company have asserted that the Company did not disclose certain information
to them prior to entering into the agreement. The entities have requested that
the Company relinquish all rights obtained by the Company and, if the Company
does not relinquish such rights, "appropriate action" will be taken. No
settlement has been reached in this matter and, to date, no suit has been filed
or demand received. Management currently cannot estimate what liability, if any,
could result from this dispute.

         Besides the above enumerated proceedings, several claims and cases have
been filed by creditors and former employees of the Company relating to unpaid
amounts for goods and services provided the Company. Payments of these amounts
are now stayed by the Bankruptcy Proceedings.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATION

         The following discussion and analysis provides information which
management (see next paragraph) believes is relevant to an assessment and
understanding of the Company's results of operations and financial condition.
The discussion should be read in conjunction with the audited consolidated
financial statements of the Company and notes thereto (Item 8 of this Report).

         The Company's executive officers during the period of this discussion
and analysis are no longer with the Company. Therefore, this discussion and
analysis is based on the knowledge of operations of those presently retained by
the Company.

RESULTS OF OPERATIONS

         As discussed in Item 1. "Business" and in Item 8. "Financial Statements
and Supplementary Data," on February 26, 1999, the Company and its wholly owned
subsidiary, Codon, filed voluntary petitions for relief under the Bankruptcy
Code. Further, the Company has disposed of substantially all of the operating
assets of its former business and currently has no revenues from operations.
Consequently, the following discussion of results of operations has no bearing
on future operations, if any, of the Company.

1998 compared to 1997

         Consolidated product sales decreased $1.3 million (10.8%) to $11.6
million in 1998 compared to $12.9 million in 1997. This decrease is
substantially due to the operations that have been disposed of or which ceased
during 1998 (see Item 1 "Business" and Note 3 to the consolidated financial
statements) offset by an approximately $1.5 million in increased sales by
Appligene. There was no significant change in contract and grant revenue between
1998 and 1997. Subsequent to the disposition of Appligene in early 1999, the
Company no longer has any revenues from operations.

         Operating expenses increased $4.3 million (13%) to $38 million in 1998
compared to $33.7 million in 1997. The majority of the increase was due to (1) a
$1.2 million in amortization of intangibles and (2) a $5.3 million in associated
with the write-off of research and development projects in process acquired in
the acquisition of outstanding shares of Codon, which ceased operations at the
end of the third quarter of 1998. These increases were offset by decreases in
other components of operating expenses due to the dispositions and
discontinuation of operations discussed above.

         Loss from operations in 1998 was $26.0 million compared to $20.4
million in 1997. This increase of $5.6 million is explained above.

         Net other expense has decreased $9.3 million from $10.6 million in 1997
to $1.3 million in 1998. The majority of items accounting for this decrease
result from the disposition of the Company's operations during 1998 discussed in
Item 1 "Business" and in the notes to the consolidated financial statements

                                       10

 under Item 8 of this Report. This decrease is primarily due to the following
(dollars in millions):

                                                             Decrease (Increase)

         The net loss applicable to common stock decreased $0.2 million in 1998
to $31.1 million from $30.9 million in 1997. This is mainly due to (1) dividends
and accretion on convertible preferred stock of $3.9 million in 1998, offset by
(2) the $9.3 change in other income (expense) less by the increase in the loss
from operations of $5.6 both discussed above.

1997 Compared to 1996

         Consolidated product sales decreased 15% to $12.9 million in 1997
compared to $15.3 million in 1995. In 1997, the sales decrease was attributable
largely to the full-year effect of the restructuring of certain product lines in
the U.S. in 1996 (-16%) and a decrease in the exchange rate of the French franc
(-6%), partially offset by an increase in sales of continuing products (+7%).

         Contract and grant revenue decreased 40% to $0.4 million in 1997
compared to $0.7 million in 1996. Four new grants were received in 1997;
however, two of the grants ended in 1998.

         Gross profit as a percentage of sales decreased 34% in 1997 from 37% in
1996. The decrease was due to certain product mix changes (2.1%) and competitive
pressures on European margins (0.5%), and to costs incurred in the United States
for validating, regulating, and scaling up the initial stages of the manufacture
of the approval of a FDA-approved controlled diagnostic product, INFORM (TM)
HER-2/neu (1.5%, more than offsetting the benefits of the restructuring
efforts). Specifically the Company discontinued the sale of certain products,
mainly high-end imaging equipment, which had high gross margins but which had
low or negative net margins after recognizing the relating selling, servicing
and collection expenses.

         The Company had no restructuring expense in 1997, the 1996 expense of
$2.1 million consisted of the revaluation of inventory of discontinued

                                       11

<PAGE>


products, charge-off of goodwill associated with such products and severance
payments to employees terminated in conjunction with the restructuring plan. The
restructuring plan was anticipated to, and did, have an effect on sales, gross
margins, and selling, general and administrative expenses. The sales declines
noted for 1997 were due in large measure to retirement from the market of more
than one hundred products, most notably the computerized imaging and Appligene
products with respect to the U.S. Gross margins declined as a result of these
actions because the gross margin on the sales of imaging systems historically
had been higher than on the weighted average gross margins of other Oncor
products. These lost margins were more than offset by savings resulting from the
termination of all imaging system employees, expenses for whom were reported
primarily in selling, general, administrative, research and development
departments.

         Amortization of intangible assets in 1997 and 1996 is due to the
amortization of the portion of the purchase price of Appligene attributable to
the value of intangible assets acquired, primarily for contracts, completed
research projects, and the excess of the purchase price over the book value of
the assets acquired. The slight decline in the amortization is due to the change
in exchange rates and the completed research projects being fully amortized
during 1996.

         Selling, general and administrative expenses decreased 2% to $14.8
million in 1997, compared to $15.1 million in 1996. The decrease was due to a
reduction in legal expenses associated with certain intellectual property
matters (decreased $1.5 million), the change in exchange rates (decreased $0.5
million), and the full year beneficial effects of the restructuring plan
instituted in the second quarter of 1996 in the U.S. (decreased $0.1 million).
These decreases were partially offset by legal and other expenses associated
with certain proposed strategic transactions (increased $1.4 million) and with a
lawsuit brought by a former employee (increased $0.4 million).

         Research and development expenses remained level at approximately $7.3
million. In 1997, the beneficial effects of the restructuring plan instituted in
the second quarter of 1996 were offset by an increase in research and
development expenses in Europe.

         Clinical and regulatory expenses decreased 20% to $2.0 million. The
decrease in 1997 is primarily due to lower costs for manufacturing validation
and regulation costs related to the application for FDA approval of its newly
approved diagnostic tests partially offset by increased staff hired to support
the Company's efforts with respect to the support of its diagnostics' products.

         As a result of the factors discussed above, net operating loss
decreased 7% to $20.4 million from $22 million in 1996.

         Investment income remained unchanged at %0.5 million. The level of
investment income is directly related to the level of investment funds which
increased in late 1996 with the private placements partially used by subsequent
cash operating losses of the Company.

         Interest and other expenses of $6.8 million and $3.1 million in 1997
and 1996, respectively, represented primarily interest expense which has become
substantially more significant through (i) the issuance of options in
conjunction with a line of credit, which bears interest at the prime rate plus
2%; (ii) the amortization of the beneficial conversion feature in the issuance
of convertible debentures in 1996; and (iii) cash interest expense. The

         In 1997 and 1996 the interest and other expenses included non-cash
charges of $6.1 million and $3.1 million, respectively.

         Equity in net loss of affiliates was $4.3 million in 1997 as compared
to $4.4 million in 1996. The Company's proportionate share of net losses
attributable to Codon in 1997 decreased compared to 1996 due to a decrease in
the Company's ownership interest in Codon.

         As a result of the factors discussed above, net loss increased 7% to
$30.9 million in 1997 compared to $29.0 million in 1996.

LIQUIDITY AND CAPITAL RESOURCES

         At December 31, 1998, the Company had a working capital deficiency of
$10.0 million and a stockholders' deficiency of $11.7 million. This compares to
working capital of $1.4 million and shareholder's equity of $3.1 million in
1997. The working capital deficiency resulted from the general decrease in cash
to meet its obligations and the liability to preferred shareholders. The
stockholders' deficiency is substantially due to the net loss for 1998 offset by
the increase in additional paid-in capital of $13.1 million resulting from the
issuance of common stock in connection with debt, issuance of warrants with the
preferred stock and issuance of warrants in connection with debt. Cash items at
December 31, 1998 totaled $1.4 million which include $1.2 million of Appligene
which was disposed of in early February 1999. Consequently, there are no
significant cash reserves available to meet liabilities. The Company will
require substantial financing to enable it to pursue future business
opportunities.

         See Item 1 "Business" and the consolidated financial statements
(principally Notes 1 and 3) under Item 8 of this Report. The Company presently
has no revenues from operations and has filed for reorganization under the
Bankruptcy Act. Oncor expects to reorganize under Chapter 11 and to propose a
reorganization plan or plans. At this time, it is not possible to predict that
any Plan filed will be approved or confirmed by the Bankruptcy Court, or that
such plans will be consummated. If a plan is not approved, the Company may be
required to liquidation.

COMMITMENTS

There were no commitments for capital expenditures at December 31, 1998.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         After the disposition of substantially all the Company's assets and
operations as discussed in Items 1, 7 and 8 of this Report, the Company has no

                    Report of Independent Public Accountants

To Oncor, Inc.

We have audited the accompanying consolidated balance sheets of Oncor, Inc. and
subsidiaries as of December 31, 1998 and 1997, and the related consolidated
statements of operations, stockholders' equity (deficiency) and cash flows for
each of the three years in the period ended December 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Oncor, Inc. and subsidiaries as
of December 31, 1998 and 1997, and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. The Company has experienced
significant losses and has a net capital deficiency of $11,700,000 at December
31, 1998. In addition, as described in Note 1 to the accompanying financial
statements, in February 1999 the Company filed a voluntary petition for relief
under Chapter XI of the U.S. Bankruptcy Code. These matters, among others, raise
substantial doubt about the Company's ability to continue as a going concern.
Management's plans in regard to these matters, including its intent to file a
plan of reorganization that will be acceptable to the Court and the Company's
creditors, are also described in Note 1. In the event a plan of reorganization
is accepted, continuation of the business thereafter is dependent on the
Company's ability to achieve successful future operations. The accompanying
financial statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts or the amounts and
classification of liabilities that might be necessary should the Company be
unable to continue as a going concern.

         of common stock for all the remaining shares of Codon Pharmaceuticals,
         Inc.

     Transactions relating to the issuance of shares of its Common Stock by the
     Company in connection with conversion of convertible debt during 1998 and
     1997 are as follows (in thousands):

     Year             Shares Issued               Value
     ----             -------------               -----

     1997             2,888                       10,317

     In 1997, the Company issued options to purchase 900,000 shares of its 25%
     owned affiliate Oncormed in consideration for establishing and extending a
     line of credit. In 1998, the Company issued options to purchase an
     additional 200,000 shares of Oncormed common stock and warrants to purchase
     2.9 million shares of Oncor, Inc. common stock in connection with the line
     of credit.








The accompanying notes are an integral part of these consolidated financial
statements.

                                   ONCOR, INC
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                             As of DECEMBER 31, 1998

1.   ORGANIZATION, BANKRUPTCY AND CERTAIN ELEMENTS OF RISK

     Chapter 11 Filing

     On February 26, 1999 (the "Petition Date"), Oncor, Inc. and its
wholly-owned subsidiary, Codon Pharmaceuticals, Inc. (the "Debtor"), filed
voluntary petitions for relief under Chapter 11 of the United States Code (the
"Bankruptcy Code") with the United States Bankruptcy Court for the District of
Delaware, Wilmington, Delaware. Under Chapter 11, certain claims against the
Debtor in existence prior to the filing of the petitions for relief under the
Bankruptcy Code are stayed while the Debtor continues as debtor-in-possession.

     Pursuant to the provisions of the Bankruptcy Code, all actions to collect
upon any of the Company's liabilities as of the Petition Date or to enforce
pre-Petition contractual obligations were automatically stayed. Absent approval
from the Bankruptcy Court, the Company is prohibited from paying pre-Petition
obligations. However, the Bankruptcy Court has approved payment of certain
pre-Petition liabilities as of the Petition Date such as employee wages and
benefits and certain specified pre-Petition obligations. Additionally, the
Bankruptcy Court has allowed for the retention of legal and financial
professionals and other payments to protect the holders of claims against the
Company. As a debtor-in-possession, the Company has the right, subject to
Bankruptcy Court approval and certain other conditions, to assume or reject any
pre-Petition executory contracts and unexpired leases. Parties affected by such
rejections may file pre-Petition claims with the Bankruptcy Court in accordance
with Bankruptcy procedures.

     As of the Petition Date, approximately $125,000 in pre-Petition December
31, 1998 liabilities of Oncor and Codon reflected in the accompanying financial
statements were paid. All remaining Oncor and Codon liabilities included in the
accompanying balance sheet still existed at the petition date and consequently
are subject to compromise under the Chapter 11 proceedings. As of December 31,
1998, the following Oncor and Codon pre-Petition liabilities are included in the
accompanying consolidated balance sheet (in thousands):

     Accounts payable                                         $ 3,565
     Accrued expenses                                           1,706
     Liability to preferred shareholders                        8,555
     Notes payable                                                629
                                                              -------
                                                              $14,455
                                                              =======

     The Company's management intends to file a plan of reorganization under
Chapter 11 that will be acceptable to the Court and the Company's creditors and
to propose a reorganization plan or plans. In the event a plan of reorganization
is accepted, continuation of the business thereafter is dependent on the
Company's ability to achieve successful future operations. At this time, it is
not possible to predict the length of time the Company will continue under
Chapter 11; that any Plan filed will be approved or confirmed by the Bankruptcy
Court; or, that such plan will be consummated. If a plan is not approved, the
Company may be required to liquidate.

     History of Operating Losses

     Oncor has not been profitable since its inception in July 1983. The Company
cannot provide assurance as to when, if ever, it will achieve profitability. As
indicated in Note 3 to the consolidated financial statements, the Company has
disposed of most of its assets and operations and currently has no revenues from
operations.

     Going-Concern and Basis of Financial Statements

     Although the Chapter 11 filings and the history of operating losses raise
substantial doubt about the Company's ability to continue as a going-concern,
the accompanying consolidated financial statements have been prepared in
accordance with generally accepted accounting principles applicable to a company
on a going-concern basis which contemplates the continuity of operations,
realization of assets and the liquidation of liabilities in the ordinary course
of business. As a result of the Chapter 11 filings, such realization of assets
and liquidation of liabilities are subject to significant uncertainties.
Specifically, the financial statements do not present the amount which will
ultimately be paid to settle liabilities and contingencies which may be allowed
in the Chapter 11 Bankruptcy reorganization cases. Also, the consolidated
financial statements do not reflect adjustments to assets which may result if
the Company is forced to liquidate all the assets. A plan of reorganization
could materially change the amounts currently included in the consolidated
financial statements.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation

     The consolidated financial statements include the accounts of Oncor, Inc.
and all subsidiaries. All significant intercompany accounts and transactions
have been eliminated in consolidation. The Company records investments in
affiliates owned more than 20%, but not in excess of 50%, using the equity
method. Changes in the Company's proportionate share of subsidiaries or
affiliate's equity resulting from common stock issuances of subsidiaries and
investments in affiliates are credited to equity.

     Management's Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting periods. Reserves have been recorded for estimates
of uncollectible accounts receivable and excess and obsolete inventory.
Management also uses estimates to determine the estimated lives of its
intangible and tangible assets. Actual results could differ from those
estimates.

     Fair Value of Financial Instruments

     Cash, accounts receivable, accounts payable, accrued liabilities and
short-term borrowing, as reflected in the financial statements, approximate fair
value because of the short-term maturity of those instruments. Warrants issued
in connection with a secured financing to purchase common stock of an affiliate
have been recorded at fair value based upon a valuation model. It was not
practicable to estimate the fair value of the Company's long-term debt because
quoted market prices do not exist and no rates are currently available to the
Company for loans with similar terms and conditions. Also, the fair value of the
Company's liabilities that are subject to compromise are not presently
determinable as a result of the Bankruptcy Proceedings.

                                      F-14

<PAGE>




     Concentration of Credit Risk

     Concentrations of credit risk with respect to receivables is generally
addressed in that the Company maintains an allowance for doubtful accounts based
upon its expectation of the proportion of its receivables it will not be able to
collect. With respect to investment in marketable securities, the Company's sole
investment consists of stock held in one publicly traded company. Market
fluctuations in that company's share price could significantly affect the
carrying value of the investment.

     Impairment of Long-Lived Assets

     The Company complies with Statement of Financial Accounting Standards
("SFAS") No. 121, Accounting for the Impairment of Long-Lived Assets to be
Disposed Of. The Company reviews its long-lived assets, including identifiable
intangibles; goodwill; and property, plant and equipment, for impairment
whenever events or changes in circumstances indicate that the carrying amount of
the assets may not be fully recoverable. To determine recoverability of its
long-lived assets, the Company evaluates that future undiscounted net cash flows
will be less than the carrying amount of the assets. Impairment is measured as
the difference between carrying cost and fair market value.

     Cash Equivalents and Investments

     Cash equivalents and investments at December 31, 1998 and 1997, consist
primarily of funds invested in money market instruments and commercial paper.
Investments with maturities between three months and one year are classified as
short-term investments. Investments in securities with original maturities of
less than three months are considered cash equivalents. The $0.4 million of
restricted cash at December 31, 1998 relates to cash held in escrow in France
pursuant to legal proceedings brought by a former employee in France.

     The Company accounts for investments in accordance with SFAS No. 115,
Accounting for Certain Investments in Debt and Equity Securities. All
investments are classified as available-for-sale securities and, accordingly,
carried at fair market value. Unrealized holding gains and losses are excluded
from earnings and reported as a net amount in a separate component of
shareholders' equity until realized. In computing gains and losses, costs are
determined on the basis of specific identification.

     Revenue Recognition

     The Company generally recognizes revenue from sales when the related goods
are shipped. Grant and contract revenues are recognized on a percentage of
completion basis. Grant revenues are reported when earned and are not refundable
in accordance with the provisions of the grant awards.

     Foreign Currency Translation

     The French franc ("FF") is the functional currency of the Company's
operations in France (subsequently disposed of, see Note 3). Assets and
liabilities for these operations have been translated into U.S. dollars using
the exchange rates in effect on the respective balance sheet dates. Revenues and
expenses have been translated using the average exchange rates during the
periods presented. Cumulated translation losses of $1.4 million and $2.2 million
at December 31, 1998 and 1997, respectively, have been excluded in determining 
the results of operations and have been accumulated as a separate component of 
equity.

     Income Taxes

     The Company accounts for income taxes in accordance with SFAS No. 109, 
Accounting for Income Taxes. (See Note 4.)

     Classification

     Certain prior year amounts have been reclassified to conform to current
year presentation.

     Basic and Diluted Net Loss Per Share

     SFAS No. 128 requires the dual presentation of basic and diluted net loss
per share. Basic net loss per share includes no dilution and is computed by
dividing net loss available to common shareholders by the weighted average
number of common shares outstanding for the period. Diluted loss per share
includes the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock.
Options, warrants and convertible securities that were outstanding at the end of
each period presented were not included in the computation of diluted net loss
per share as their effect would be antidilutive. As a result, the basic and
diluted loss per share amounts are identical.

     Research and Development Costs

     Expenditures for research and development activities are charged to expense
when incurred.

     New Accounting Pronouncements

     Effective January 1, 1998, the Company implemented SFAS No. 130 "Reporting
Comprehensive Income." This pronouncement established standards for reporting
and display of comprehensive income and its components in a full set of general
purpose financial statements. Comprehensive income is the total of net income
and all other non-owner changes in equity. Foreign currency translation
adjustments and unrealized holding gains on investments are the significant
components of comprehensive income.

     Also, effective January 1, 1998, the Company implemented SFAS No. 131
"Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 131 requires an enterprise to report certain additional financial and 
descriptive information about its reportable segments. (See Note 8.)


3.   SIGNIFICANT DISPOSITION OF ASSETS

     During 1998, as part of the Company's plan to reduce its scope of
operations and ongoing operating expenses, the Company disposed of a significant
portion of its business and the related assets.

     Codon Pharmaceuticals, Inc.

     Effective February 28, 1998, the Company acquired all remaining outstanding
shares of Codon Pharmaceuticals, Inc. ("Codon") in exchange for 1.65 million
shares of Oncor common stock. The acquisition was accounted for as a purchase.
The value of the Oncor common stock exchanged was approximately $6.2 million. Of
this amount, 

                                      F-16

<PAGE>

$5.7 million, representing estimated value of Codon's proprietary position in
certain technologies under development for future products which have not yet
been developed to a stage of technological feasibility and for which the
ultimate realizability is uncertain was written off during the first quarter of
1998.

     On October 1, 1998, Codon ceased all operations. Codon's remaining assets
were liquidated through a public auction in November 1998. As a result, the
Company recorded an impairment loss based on the sales price of assets of
approximately $529,000.

     Genetics Assets (Vysis, Inc. Transaction)

     On April 9, 1998, the Company completed a transaction with Vysis, Inc. in
which Oncor conveyed to Vysis $0.5 million in cash and full rights and title to
its non-oncology genetics probe assets ("Genetics Assets"), including primarily
inventories (approximately $1.2 million) and intellectual property, in exchange
for two licenses to patents held by Vysis. (These two licences were surrendered
in the November 24, 1998 transaction discussed below.) In addition, the parties
agreed to settle all legal action between them with respect to a suit brought by
Vysis against the Company in September 1995. The Company recorded as an
intangible asset the value of the licenses acquired in an amount of $1.7 million
equal to the net book value of the assets conveyed. Accordingly, no gain or loss
was recognized in the disposition of the Genetic Assets.

     Research Products Assets(Intergen Transaction)

     On June 30, 1998, the Company completed the sale of its Research Products
Assets, including primarily inventory, laboratory equipment and intellectual
property, to Intergen Company for cash consideration of $3.1 million. A gain of
approximately $2.0 million was recorded on the sale representing the excess of
the cash consideration received over the net book value of the assets sold.

     Oncormed, Inc. (Gene Logic Transaction)

     On September 28, 1998, pursuant to a plan of merger between Oncormed, Inc.
and Gene Logic, Inc. ("Gene Logic"), the Company exchanged 900,000 shares
representing all its shares in Oncormed for approximately 420,000 shares of Gene
Logic common stock. A gain of approximately $1.7 million was recorded on the
transaction, representing the estimated net realizable value of the Gene Logic
shares. Prior to this transaction, the Company accounted for its investment in
Oncormed under the equity method of accounting. Such investment had been
completely written off due to Oncormed's operating losses.

     The market value of the Gene Logic shares was approximately $2.9 million at
December 31, 1998. Accordingly, an unrealized gain of $1.2 million has been
recorded in stockholders' equity (deficiency). The market value of the Gene
Logic shares held at March 31, 1999 was approximately $1.9 million. The change
is due both to a decline in the market value and a sale of approximately 30,000
shares.

     In Situ Hybridization Technology Assets (Ventana Transaction)

     On November 23, 1998, the Company voluntarily surrendered assets related to
its in situ Hybridization business to certain of the Company's secured
creditors. The creditors then sold the assets to Ventana Medical Systems
("Ventana"). The purchase price was $5 million with an additional $0.5 million
due the Company contingent on certain events.

     Proceeds from the sale to Ventana were used to satisfy secured creditors
for approximately $4.2 million, pay legal fees of approximately $0.2 million and
pay incentive amounts to certain members of management of approximately $0.5
million. The remaining $0.2 million was received by Oncor prior to year end.

                                      F-17

<PAGE>




     The Company recorded a gain on the disposition of these assets of
approximately $0.4 million representing the excess of the value received over
the net book value of the assets surrendered (approximately $4.6 million). The
$0.5 million contingent portion of the purchase price was not recorded pending
removal of the contingencies. The ultimate receipt of any of this amount is not
known at this time.

     Appligene Oncore

     On February 10, 1999, the Company sold its 80% interest in Appligene Oncore
("Appligene"), a French company, to a Canadian company for $1 million.

     The amounts included in the accompanying financial statements relating to
Appligene are (in thousands):

     Revenues                                   $7,182
     Net loss                                   (1,836)
     Total assets                                4,988
     Total liabilities                           3,356

The minority interest in consolidated subsidiary of $2.0 million and the
deferred cumulative translation adjustment of $1.4 million at December 31, 1998
relate to Appligene.

     The equity in Appligene at December 31, 1998 has been written down to net
realizable value of approximately $0.8 million, the net amount (including a
provision for estimated 1999 net loss of approximately $0.1 million) realized in
the sale of Appligene in February 1999.

     The following pro forma, unaudited balances comprise the Company's
summarized consolidated balance sheet as of December 31, 1998, assuming its
interest in Appligene was sold as of that date and net cash proceeds of $0.8
million were received (dollars in thousands).

                                                                    (Unaudited)

4.   INCOME TAXES

     With respect to U.S. federal income tax, as of December 31, 1998 the
Company has net operating loss carry-forwards ("NOL's") of approximately $122
million available to offset future taxable income. The Company also has research
and development tax credits of approximately $1.8 million available to reduce
future U.S. federal income tax. The NOL and research and development credits may
be used through 2018, but began to expire in 1998. Despite the NOL and credit
carry-forwards, the Company may have an income tax liability in future years due
to the application of the alternative minimum tax rules. In addition, the
utilization of these tax NOL's and credit carry-forwards is subject to statutory
limitations regarding changes in ownership and the bankruptcy proceedings.

     SFAS No. 109 requires that the tax benefit of financial reporting NOL's and
tax credits be recorded as an asset to the extent that management assesses the
utilization of such NOL's and tax credits to be "more likely than not." The
Company's net deferred tax assets, the only material element of which is net
operating loss carry forwards, was approximately $50.9 million at December 31,
1998 and $43.9 million at December 31, 1997. A valuation reserve was recorded
against the entire amount of the net deferred tax assets, since the Company has
incurred operating losses in the United States since inception. The net deferred
tax assets are primarily attributable to net operating losses, capital losses
and tax credits.

Net operating loss and research and development credits relating to and
available only for the French operations were lost with the disposition of
Appligene in 1999.


5.   RESTRUCTURING EXPENSE

     In 1996, the Company adopted a restructuring plan to discontinue the
development, manufacture, sale and support of certain imaging, research and
non-oncology products. Recorded restructuring costs of $2.1 million comprise the
charge-off of discontinued products, charge-off of goodwill associated with a
related business unit, and severance payments to former employees whose
employment was terminated in conjunction with the plan. The discontinued product
lines were customized, computerized, microscopic imaging systems, certain
gene-based DNA probes chemistries and certain other chemical test kits and
components. The related charge was incurred in conjunction with the Company's
decision to cease field sales and support for these lines.

6.   STOCKHOLDERS' EQUITY

     Preferred Stock

     In January 1998, the Company completed a $5 million equity financing in a
private placement of 500 shares of Series A preferred stock. The preferred stock
is convertible into common stock of the Company under certain circumstances,
generally in a period beginning after 90 days, at prices equal to the lower of
(i) 100% (reducing over time to 90%) of the average of the lowest closing bid
price of the common stock on any two of the most recent 22 trading days
preceding the date of conversion and (ii) $4.56. Dividends at rate of 6% are
payable upon conversion in cash or common stock. In addition, the Company issued
warrants to purchase 125,000 shares of common stock in connection with the
transaction, with an exercise price of $5.16 per share. The investors and the
Company each have rights to increase the amount of the investment under certain
circumstances. Approximately $0.3 million of the net proceeds was allocated to
the value of the warrants.

     Subsequent to December 31, 1998, holders of the preferred stock converted 6
shares of preferred stock into 1,997,992 shares of the Company's common stock.

     In addition, the Series A preferred stock agreements provide for redemption
rights upon the occurrence of certain events. Although disputed by the Company,
the holders of the preferred stock believe that those events occurred during
1998 and, accordingly, the Company has recorded $8.6 million as a current
liability in the accompanying consolidated balance sheet, representing the
redemption values plus additional accrued charges and interest as specified in 
the private placement

                                      F-20

<PAGE>



agreements. Additional interest of approximately $0.9 million that under the
agreements accrues upon satisfaction of certain redemption requirements of the
shareholders has not been recorded.

     Common Stock, Convertible Notes and Warrants

         On December 30, 1996, the Company completed a private placement of 6%
five-year unsecured notes convertible into shares of Common Stock of the Company
and warrants to purchase an aggregate of 250,000 share of the Company's Common
Stock. The Company received total proceeds of approximately $10.0 million of
which $0.4 million was allocated to the warrants. Issuance costs were not
significant. The notes are immediately convertible at the option of the holder
and were to be automatically converted upon maturity. The notes are convertible
at the lesser of $5 per share or 80.0% of the market value of the Common Stock
at the time of conversion over a period of approximately five months.

     During the three years ended December 31, 1998, the Company had two other
similar private placements. All these notes had been converted.

     On all of the convertible debt instruments with beneficial conversion
features, the Company records as interest expense the difference between the
conversion price and the quoted price of the stock issuable upon conversion of
convertible debentures with a fixed conversion benefit. The imputed interest is
recorded over the minimum holding periods of the debentures pursuant to which
the maximum beneficial conversion feature is earned. The interest expense
recorded in 1998, 1997 and 1996 pursuant to this accounting convention is
approximately $0.1 million, $3.0 million and $2.6 million, respectively.

     In August 1998, warrant holders exercised options to acquire 1.1 million
shares of Oncormed common stock from Oncor at exercise prices of $0.75 to $1 a
share. The Company recorded a gain on the exercise in the amount of
approximately $1.0 million. In addition, the Company recognized the deferred
gain recorded upon the granting of the warrants. During 1998, the Company also
granted warrants to purchase an aggregate of 2.9 million shares of its common
stock at exercise prices ranging from $0.50 to $1.00 per share in connection
with financing received.

     Stock Options

     The Company maintains a Stock Option Plan (the "1992 plan")which was
approved by the Board of Directors in 1992. This 1992 plan incorporated the
Company's former Incentive Stock Option Plan, Non-Qualified Stock Option Plan
and Non-Qualified Stock Option Plan for Non-Employee Directors.

     The aggregate number of shares available for issuance under the 1992 Plan
may not exceed 5,015,604 shares of Common Stock, subject to adjustment from time
to time in the event of certain changes to the Company's capital structure.

     In May 1997, the Board of Directors authorized a regrant program (the "1997
Regrant Program") which allowed active current option holders, excluding
executive officers, to forego earned vesting and elect to exchange all or some
of their outstanding options, ranging in exercise price from $4.125 to $7.50 per
share, for new options under the Company's 1992 Plan, to purchase shares of the
common stock at a new price of $3.625, the closing price on May 23, 1997, the
regrant date under the 1997 Regrant Program. Options to purchase approximately
462,000 shares of common stock were canceled and regranted. Stock options that
were regranted began vesting over a four-year period measured from May 23, 1997.

                                      F-21

<PAGE>



     In June, 1998, the Board of Directors authorized a second regrant program
(the "1998 Regrant Program") which allowed active current option holders to
exchange options ranging in exercise price from $1.0625 to $6.875 per share, for
new options to purchase shares of the common stock at a new price of $0.875,
the closing price on June 1, 1998, the regrant date under the 1998 Regrant
Program. Options to purchase approximately 2,019,000 shares of common stock were
canceled and regranted.

     The Company accounts for this plan under APB Opinion No. 25, under which no
compensation cost has been recognized. Had compensation cost for these plans
been determined consistent with SFAS No. 123, the Company's net income and
earnings per share would have been reduced to the following pro forma amounts:

                                                    1997          1996
                                                    ----          ----
Net Loss (in thousands): As Reported              $(30,947)     $(28,980)
                         Pro Forma                $(32,814)     $(30,545)

Net Loss Per Share:      As Reported              $(1.21)       $(1.26)
                         Pro Forma                $(1.28)       $(1.33)


Because the method of accounting promulgated by the Statement has not been
applied to options granted prior to January 1, 1995, the resulting pro forma
compensation cost may not be representative of that to be expected on a pro
forma basis in future years.

     The fair market value of each option grant is estimated using the
Black-Scholes option pricing model with the following assumptions used for each
year: risk-free interest rates of 4 percent; expected lives of 5.9 years for the
options; and expected volatility of 56%.

     The effects of the provisions of SFAS No. 123 on 1998 pro forma results are
not material, taken as a whole.

7.   COMMITMENTS AND CONTINGENCIES

     On April 27, 1998, the Company received a summons and complaint in
connection with a lawsuit entitled Key Technology, Inc. v. Oncor, Inc. in the
Superior Court of the State of Washington for the County of Walla Walla. The
complaint alleges breach of contract and fraud in connection with a June 1996
asset purchase agreement between Key Technology and the Company relating to the
sale of the Company's 1300 video inspection systems to Key Technology, and seeks
damages against the Company of $1,475,000. A failure to successfully defend
against or settle that suit would likely result in damages being assessed
against the Company. Management currently can not estimate what liability, if
any, could result from this dispute.

     During 1998, two entities who entered into a partnership agreement with the
Company have asserted that the Company did not disclose certain information to
them prior to entering into the agreement. The entities have requested that the
Company relinquish all rights obtained by the Company and, if the Company does
not relinquish such rights, "appropriate action" will be taken. No settlement
has been reached in this matter and, to date, no suit has been filed or demand
received. Management currently can not estimate what liability, if any, could
result from this dispute.

     In addition to the above enumerated proceedings, a number of claims and
cases have been filed by creditors and former employees of the Company relating
to unpaid amounts for goods and services provided the Company. Payments of these
amounts are now stayed by the Bankruptcy Proceedings.

     The Company leases office space and laboratory facilities under operating
lease agreements which expire in periods from 1999 to 2004. Lessor concessions
with respect to the space buildout and rental abatement, result in a deferred
rent credit at December 31, 1997 of $0.3 million. Rental expense for the years
ended December 31, 1998, 1997 and 1996 was approximately $1.0 million, $0.9
million and $0.8 million, respectively. Minimum lease payments under these lease
agreements at December 31, 1998 are as follows (in thousands):

                                                           ===

     In February 1995, the Company entered into a lease which was accounted for
as a capital lease with a net present value of future obligations of
approximately $1.2 million as of December 31, 1998.

8.       LINE OF CREDIT

     During 1997, the Company obtained a $3 million line of credit which expired
in 1998. Outstanding borrowing at December 31, 1997 were $3 million. The
interest rate effective for the line of credit as of December 31, 1997 was
7.58%. The Company issued options to purchase 900,000 shares of Oncormed, Inc.
(a 25% owned affiliate), held by the Company in conjunction with establishing
and extending this line of credit. The Company valued the options at
approximately $3.8 million. Approximately $1.8 million of the value of the
options was recorded as a charge to interest and other non-operating expense in
1997. The remaining deferred financing fees were charged to expense in 1998 as
the line of credit was paid in full in 1998.

9.   RETIREMENT PLAN

     In 1991, the Company adopted a defined contribution savings plan (the
"Plan") in accordance with Section 401(k) of the Internal Revenue Code. The Plan
covers all permanent employees who have attained the age of 21. Under the Plan,
the Company may make discretionary contributions. The Company had made no
discretionary contributions to date and has no plans to do so.

              Report of Independent Public Accountants on Schedules


To Oncor, Inc.:

We have audited, in accordance with generally accepted auditing standards, the
consolidated financial statements of Oncor, Inc., and subsidiaries included in
this Form 10-K and have issued our report thereon dated April 13,1999. Our
audits were made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The Schedule II Valuation and Qualifying Accounts
is the responsibility of the Company's management and is presented for purposes
of complying with the Securities and Exchange Commission's rules and is not part
of the basic financial statements. This schedule has been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, fairly states, in all material respects the financial data
required to be set forth therein, in relation to the basic financial statements
taken as a whole.
