UNAUDITED INTERIM FINANCIAL INFORMATION:

         The accompanying unaudited interim financial statements have been

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

RECENT PRONOUNCEMENTS:

         In March 1998, the American Institute of Certified Public
Accountants issued Statement of Position 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." This standard
requires companies to capitalize qualifying computer software costs, which
are incurred during the application development stage and amortize them over
the software's estimated useful life. Statement of Position 98-1 is effective
for fiscal years beginning after December 15, 1998. The adoption of Statement
of Position 98-1 had no impact on the Company's financial statements.

         In April 1998, the American Institute of Certified Public
Accountants issued Statement of Position 98-5, "Reporting on the Costs of
Start-Up Activities." This standard requires companies to expense the costs
of start-up activities and organization costs as incurred. In general,
Statement of Position 98-5 is effective for fiscal years beginning after
December 15, 1998. The adoption of Statement of Position 98-5 had no impact
on the Company's financial statements.

         In June 1998, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement establishes
new standards of accounting and reporting for derivative instruments and
hedging activities. This statement requires that all derivatives be
recognized at fair value in the statement of financial position, and that the
corresponding gains or losses be reported either in the statement of
operations or as a component of comprehensive income, depending on the type
of hedging relationship that exists. Statement No. 133 will be effective for
fiscal years beginning after June 15, 2000. Conductus does not currently hold
derivative instruments or engage in hedging activities.

</TABLE>

         All of the credit facilities contain reporting and financial
covenants. In the event of default on any of these covenants, no further
amounts would be advanced to the Company under any facility. Additionally,
the entire amounts outstanding could become due and payable immediately upon
default and those assets that are collateralized could be seized, unless the
lender waives such default. At September 30, 1999, Conductus was in
compliance with all financial covenants.

5.       LICENSE AGREEMENT:

         On May 4, 1999, the Company entered into a definitive agreement with
General Dynamics Information Systems, Inc. (GDIS) to license its high
temperature superconductive (HTS) electronics and cryoelectronics technology.
Under the license agreement, GDIS purchased rights to Conductus' HTS
thin-film technology and other intellectual property for $5,000,000 plus
future royalties and will have rights to use and sell this technology for use
in U.S. Government or state, local and foreign government markets, as
defined. Under the license agreement, GDIS made an immediate payment to the
Company of $2,900,000. In addition, GDIS will pay the Company $175,000 on the
first day of each month for 12 months beginning on July 1, 1999. The Company
and GDIS also entered into a Cross-License, Supply and Training Agreement
under which the Company and GDIS agreed to cross-license any updates to the
licensed technology developed by either party. Additionally, the Company will
provide product and training to GDIS in exchange for payment at standard
commercial rates from GDIS. As a result of this transaction, Conductus
recognized revenues of $5,000,000 during the quarter ended June 30, 1999,
which represented 68% of total revenues for the nine-month period ended
September 30, 1999.

6.       EFFECTS OF RESTATEMENTS:

         The Company issued 2,461,227 shares of Series B convertible
preferred stock on September 11, 1998 and September 22, 1998.

         The Series B convertible preferred stock is are subject to
redemption requirements that are outside of the control of the Company under
certain limited circumstances as defined in the Series B certificate of
designation. Those circumstances include a change in control of the Company
in which 50% or more of the voting power of the Company is disposed of or a
sale of all or substantially all of the assets of the Company. Under such
circumstances, the holders of Series B convertible preferred stock are
entitled to receive, prior to and in preference to any distribution of any of
the assets of the Company to the holders of common stock, an amount per share
equal to $2.70 plus any unpaid dividends for each share of Series B
convertible preferred stock.

         Although the Company believes that the likelihood of redemption
occurring is remote, it has restated its financial statements at December 31,
1998 and at and for the three-month period ended September 30, 1999 to
account for the redemption features of the Series B convertible preferred
shares. The carrying value of the Series B convertible preferred stock, which
was previously presented as a component of stockholders' equity, has been
reclassified outside of stockholders' equity at September 30, 1999.

         The restatement of the financial statements at September 30, 1999
and for the three-month period then ended, for the matter described above had
