October 28, 2003 in the Court of Chancery of the State of Delaware in and for New Castle County by TM Capital Corp. (TM Capital), a past financial advisor to us, under which TM Capital claimed to be entitled to cash and equity compensation with
respect to our October 2003 public equity offering. On April 4, 2005, TM Capital and we agreed to resolve all claims between us and entered into a settlement agreement that provides for, among other things, the cash payment by us to TM Capital of
$1,700,000 and the issuance by us to TM Capital of a common stock purchase warrant for 200,000 shares of our common stock, exercisable for a five-year term, with an exercise price of $9.50 per share. TM Capital and we also entered into a
registration rights agreement wherein we agreed to register for public resale the shares of our common stock issuable upon exercise of the warrant (as the same may be transferred or assigned). TM Capital assigned its rights to receive a portion of
the warrant to its legal counsel, Klehr, Harrison, Harvey, Branzburg &amp; Ellers, LLP. The warrants were issued in reliance upon the exemptions from registration under Section 4(2) of the Securities Act of 1933, as amended (the Securities Act),

systems that generate, deliver and use electric power. Our products include high temperature superconductor (HTS) wire for electric power, transportation, medical and industrial processing applications; motors and generators based on our HTS wire
for ship propulsion and industrial uses, as well as synchronous condensers for transmission and distribution grid reliability; and advanced power electronic systems that ensure the quality and reliability of electricity for residential, commercial
and industrial end users. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Our HTS wire carries direct current
(DC) without any loss of electrical power, resulting in high electrical efficiency. Our HTS wire also conducts more than 140 times the electrical current of copper wire of the same dimensions, which dramatically reduces the size and weight of
electrical equipment made with our HTS wire and significantly increases the power throughput of power cables. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT

FACE="Times New Roman" SIZE="2">The first generation (1G) HTS wire we are manufacturing and selling today to customers in 11 countries around the world has been critical to the development of large-scale superconductor applications, such as power
transmission cables, electrical motors and generators for marine propulsion, synchronous condensers for grid reliability, and HTS coils for magnetically levitated train systems, analytical instruments and industrial processing equipment. </FONT></P>

the next several years. We expect the electrical performance and mechanical strength of our 2G HTS wire to meet or exceed that of 1G HTS wire, while manufacturing costs are reduced by a factor of two to five times. We have also designed our 2G HTS
wire to be a &#147;form, fit and function&#148; replacement for our 1G HTS wire. Based on 2G HTS wire&#146;s improved performance, substantially lower manufacturing costs and ease of replacement for 1G HTS wire, we expect markets to rapidly adopt
products based on 2G HTS wire as soon as it is available in commercial quantities. During the last year, we have made significant technical and manufacturing advances on our proprietary 2G HTS wire. Accordingly, we have concluded that now is the
time to invest in the scale-up of 2G HTS wire manufacturing and to accelerate the transition from 1G to 2G HTS wire. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P

right of the U.S. government to terminate its contract with us, U.S. government contracts are conditioned upon the continuing approval by Congress of the necessary spending to honor such contracts. Congress often appropriates funds for a program on
a fiscal-year basis even though contract performance may take more than one year. Consequently, at the beginning of many major governmental programs, contracts often may not be fully funded, and additional monies are then committed to the contract
only if, as and when appropriations are made by Congress for future fiscal years. There can be no assurance that our U.S. government contracts will not be terminated or suspended in the future. The U.S. government&#146;s termination of, or failure
to fully fund, one or more of our contracts would have a negative impact on our operating results and financial condition. Further, in the event that any of our government contracts are terminated for cause, it could affect our ability to obtain

have a significant effect on the market price of our common stock. In addition, the stock market in general, and the stock of high technology companies in particular, have in recent years experienced extreme price and volume fluctuations, which are
often unrelated to the performance or condition of particular companies. Such broad market fluctuations could adversely affect the market price of our common stock. Due to these factors, the price of our common stock may decline and investors may be
unable to resell their shares of our common stock for a profit. Following periods of volatility in the market price of a particular company&#146;s securities, securities class action litigation has often been brought against that company. If we
become subject to this kind of litigation in the future, it could result in substantial litigation costs, a damages award against us and the diversion of our management&#146;s attention. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT

reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause

defending a civil or criminal action, suit or proceeding may be paid by the registrant upon receipt of an undertaking by the director or officer to repay such amount if the registrant ultimately determines that he is not entitled to indemnification.
