Item 4.  Purpose of Transaction

     On February 26, 1999, Wilmington Securities, Inc., the Henry L. Hillman 
Trust, the JLHS 1976 Trust, the AHF 1976 Trust, the HLH Jr. 1976 Trust and 
the WTH 1976 Trust (collectively the "Investors") entered into an Exchange 
Agreement with the Issuer pursuant to which the Investors agreed to exchange 
their Series A, A-1 and B Convertible Preferred Stock and related warrants 
held by the Investors for shares of the Issuer's Series A-2, A-3 and B-1 
Convertible Preferred Stock and replacement warrants and additional warrants 
(collectively the "February Warrants") that are convertible into or 
exercisable for shares of Common Stock, upon the terms and subject to the 
limitations and conditions set forth in the Certificates of Designations, 
Rights, Preferences, Privileges and Restrictions with respect to the Series 
A-2, A-3 and B-1 Preferred Stock and in the February Warrants.

     On March 5, 1999 Wilmington Securities, Inc. entered into a Stock 
Purchase Agreement with the Issuer pursuant to which Wilmington Securities, 
Inc. purchased 41,667 shares of Series C Preferred Stock for $3,000,000.  
Wilmington Securities, Inc. also received a Warrant (the "March Warrant") for 
120,000 shares of Common Stock.

     The Series A-2, Series A-3, Series B-1 and Series C Preferred Stock of 
the Company, and the February Warrants and March Warrants (collectively the 
"Securities"), are not convertible into or exercisable for (as the case may 
be) shares of Common Stock in excess of 1,533,709 shares (the "19.9% Cap" or 
the "Allowed Conversion Shares"), unless the Company has received stockholder 
approval to eliminate such 19.9% Cap at a duly held meeting of stockholders 
in calendar 1999 (the "Stockholder Approval").  Until Stockholder Approval has 
been obtained (or, if Stockholder Approval is not obtained, then continuing 
thereafter) the 19.9% Cap shall apply and each Investor holding Securities 
shall have the right to convert its Preferred Stock or exercise its Warrants 
only up to its pro rata portion of the Allowed Conversion Shares.  The table 
below lists the number of shares of Common Stock which each Investor may 
obtain by converting or exercising its Preferred Stock or Warrants, as the 
case may be, prior to and after Shareholder Approval.

     The Company has agreed in the Stock Purchase Agreement to use its best 
efforts to obtain Stockholder Approval at the Company's 1999 Annual Meeting 
of Stockholders to be held on or before June 2, 1999.   Also, subject to 
Stockholder Approval, the Company has agreed to appoint two designees of the 
Investors to its Board of Directors at the first meeting of the Board 
following the Annual Meeting, and to use its best efforts to obtain the 
election of such designees at each subsequent Annual Meeting so long as 
Wilmington Securities, Inc. holds at least 33,750 shares of Series C 
Preferred Stock.  The two designees of the Investors are Joseph C. Manzinger
and Richard M. Johnston, each a Vice President of The Hillman Company.

          Except as set forth above and in Item 6 below, the Registrants have 
no present plans or proposals which relate to or would result in (a) the 
acquisition by any person of additional securities of the Issuer or the 
disposition of securities of the Issuer, (b) an extraordinary corporate 
transaction, such as a merger, reorganization, or liquidation involving the 
Issuer or any of its subsidiaries, (c) a sale or transfer of a material 
amount of the assets of the Issuer or any of its subsidiaries, (d) any change
in the present Board of Directors or Management of the Issuer including any
plans or proposals to change the number or term of Directors or to fill any
existing vacancies on the Board, (e) any material change in the present
capitalization or dividend policy of the Issuer, (f) any other material change
in the Issuer's business or corporate structure, (g) changes in the Issuer's 
charter, by-laws or instruments corresponding thereto or other actions which
may impede the acquisition of control of the Issuer by any person, (h) causing
a class of securities of the Issuer to be delisted from a national securities
exchange or to cease to be authorized to be quoted in an inter-dealer quotation
system of a registered national securities association, (i) a class of equity 
securities of the Issuer becoming eligible for termination of registration
pursuant to Section 12(g)(4) of the Act of 1933, or (j) any action similar to
those enumerated above.

EXCHANGE AGREEMENT


     THIS EXCHANGE AGREEMENT (the "Agreement") is made and entered into as of 
February 26, 1999, by and among Superconductor Technologies, Inc. a Delaware 
corporation (the "Company"), and the current holders (each a "Holder," and 
collectively, the "Holders") of the Company's Series A Convertible Preferred 
Stock, Series A-1 Convertible  Preferred Stock, and Series B Convertible 
Stock 
and the related warrants (collectively, the "Existing Securities") in the 
amounts set forth on Exhibit A hereto. 

Background

     A. The Company anticipates consummating an equity financing in the 
future 
(the "Series C Preferred Financing").

     B.In order to achieve compliance with NASDAQ Marketplace Rule 4460 and 
to 
meet NASDAQ's concerns regarding the past issuances of the Existing 
Securities, and to avoid any concerns regarding the potential future issuance 
of securities in a new financing, the Company's Board of Directors (the 
"Board") has determined it to be in the best interests of the Company and its 
stockholders to exchange the Existing Securities for new shares of Series 
A-2, A-3 and B-1 Convertible Preferred Stock and related warrants 
(collectively, 
the "New Securities") that are substantially the same as the Existing 
Securities except for the following features:

          1.Conversion/exercise/anti-dilution features:  Prior to the receipt 
of Stockholder Approval (as defined below), the conversion, exercise and 
price anti-dilution features of all the New Securities (plus: (i) the 
securities to 
be issued in the Series C Preferred Financing and (ii) the New Warrants (as 
defined below)) would be limited to an aggregate of 1,533,709 shares of the 
Company's Common Stock (the "19.9% Cap"), which represents 19.9% of the total 
outstanding capital stock of the Company on March 25, 1998.  The stockholders 
will be requested to approve the elimination of the 19.9% Cap and the 
issuance of additional securities.  The requisite vote (the "Stockholder 
Approval") 
will be a majority of the shares present and voting at the meeting, excluding 
any New Securities (and any securities issued in the Series C Preferred 
Financing).

          2.Dividend features:  If Stockholder Approval is not obtained, the 
New Securities would have a cumulative mandatory dividend equal to 20% per 
annum, payable in cash.  Such dividends would begin to accrue as of the dates 
the Existing Securities were first issued.

          3.Redemption Features:  The New Securities will not have any 
redemption features.  In consideration for the elimination of the redemption 
feature of the Existing Securities, the Company will issue warrants to 
purchase 75,000 shares of the Company's Common Stock at an exercise price 
equal to $7.00 per share (the "New Warrants"), subject to the 19.9% Cap.

          4.Anti-dilution Features:  The anti-dilution features will be 
amended to exclude  the securities to be issued in the Series C Preferred 
Financing and to make certain other changes as set forth in the Certificates 
of Designation (as defined below) attached as Exhibits B, C and D hereto.

C. The New Securities to be issued to the Holders in exchange for their 
Existing Securities will be subject to the Second Amended and Restated 
Stockholder Rights Agreement and the Amended Registration Rights Agreement, 
both of which will be entered into by the Company and the Holders before the 
Closing (as defined below).

     NOW, THEREFORE, the parties agree as follows:

          1.     Authorization; Issuance of Securities; Closing.

this Agreement, the Board has authorized (i) the filing of Certificates of

Preferred Stock (collectively, the "Certificates of Designation") attached as 
Exhibits B, C, and D hereto; (ii) the exchange of the Existing Securities for 
the New Securities as described in Section 1(b) below; and (iii) the issuance 
of the New Warrants as described in Section 1(b) below.

               (b)     Prior to the Closing (as defined below), the Company 
shall cause the  Certificates of Designation to be filed with the Delaware 
Secretary of State.  At the Closing, (i) the Holders shall have delivered the 
stock certificates and warrants representing the Existing Securities and the 
completed Letter of Transmittal attached as Exhibit E and; (ii) in exchange 
therefor, the Company shall deliver to the Holders certificates representing 
127,084 shares of its New Securities, the related warrants and the New 
Warrants (in substantially the form attached as Exhibit F), allocated to the 
Holders as indicated in the attached Exhibit A.

               (c)     The closing (the "Closing") of the transactions 
contemplated hereby shall be held at the offices of Wilson Sonsini Goodrich & 
Rosati, 650 Page Mill Road, Palo Alto, California on February 26, 1999, 
subject to satisfaction or waiver of the conditions to Closing set forth in 
Section 2 below.

          2.     Approval from Holders.  By executing this Agreement, the 
Holders: (i) approve the creation of Series C Preferred Stock with the 
rights, preferences and privileges as set forth in the Certificate of 
Designation 
delivered to the Holders and the issuance of such shares and related warrants 
all as set forth in the Series C Preferred Stock Purchase Agreement delivered 
to the Holders (the "Series C Agreement"); (ii) waive their rights of first 
refusal contained Section 2 of the Amended and Restated Stockholders 
Agreement, dated August 11, 1998, and Section 4 of the Securities Purchase 
Agreement, dated September 2, 1998 (the "Securities Purchase Agreement") with 
respect to the shares of Series C Preferred Stock, the warrants to be issued 
pursuant to the Series C Agreement, the Letter Agreement between the Company 
and Tanner Unman Securities, Inc., dated as of August 10, 1998, and the New 
Securities and the New Warrants pursuant to this Agreement; (iii) amend 
Section 4(e) of the Securities Purchase Agreement to add an additional 
exclusion from the definition of "Capital Raising Limitations" for the New 
Securities and the securities issuable under the Series C Agreement; and (iv) 
amend the Securities Purchase Agreement, dated September 2, 1998, to replace 
the form of warrant attached thereto as Exhibit B with the form of warrant 
attached as Exhibit I and change the references to "Series B Preferred Stock" 
to "Series B-1 Preferred Stock."

          3.     Conditions to Closing.  The obligations of the parties under 
this Agreement are subject to the fulfillment or waiver on or before the 
Closing of the following conditions:

               (a)     Covenants.  All covenants, agreements and conditions 
contained in this Agreement to be performed by the parties on or prior to the 
Closing shall have been performed or complied with in all material respects.

               (b)     Second Amended and Restated Stockholder Rights 
Agreement and Amended and Restated Registration Rights Agreement.  The 
parties shall have entered into the Second Amended and Restated Stockholders 
Rights 
Agreement and Amended Registration Rights Agreement in the forms attached as 
Exhibit G and H, respectively.

               (c)     Receipt of all Existing Securities.  The Company shall 
have received  from the Holders all the stock certificates and warrants 
representing the Existing Securities as set forth on Exhibit A (or lost stock 
or warrant affidavits for the same) and the related Letters of Transmittal 
fully executed and delivered.
               
               (d)     Blue Sky.  The Company shall have obtained all 
necessary Blue Sky law permits and qualifications, or have the availability 
of exemptions therefrom, required by any state for the offer and exchange of 
the Shares.

               (e)     Opinion of Company Counsel.  The Holders shall have 
received from Wilson Sonsini Goodrich & Rosati, counsel to the Company, an 
opinion addressed to the Holders, dated the day of the Closing and in 
substantially the form attached as Exhibit J.

          4.     Investment Representations of the Holders.  Each Holder of 
Existing Securities represents and warrants to the Company as follows:

               (a)     The Holder is acquiring the New Securities for 
investment for his or her own account only and not with a view to, or for 
resale in connection with, any "distribution" thereof within the meaning of 
the Securities Act of 1933, as amended (the "Securities Act").

               (b)     The Holder acknowledges and understands that the New 
Securities constitute "restricted securities" under the Securities Act and 
have not been registered under the Securities Act in reliance upon a specific 
exemption therefrom, which exemption depends upon, among other things, the 
bona fide nature of such Holder's investment intent as expressed herein.  The 
Holder is an "accredited investor" within the meaning of Regulation D, Rule 
501(a), promulgated by the Securities and Exchange Commission.

               (c)     The certificates evidencing the New Securities will be 
imprinted with the following legend:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR 
INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS 
AMENDED. SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH 
REGISTRATION UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY 
ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE 
REGISTRATION REQUIREMENTS OF SAID ACT.

          5.     Miscellaneous.

               (a)     Governing Law.  This Agreement shall be governed in 
all respects by the internal laws of the State of Delaware.

               (b)     Survival.  The representations, warranties, covenants 
and agreements made herein shall survive any investigation made by any of the 
parties hereto and the closing of the transactions contemplated hereby.
               (c)     Successors and Assigns.  Except as otherwise provided 
herein, the provisions hereof shall inure to the benefit of, and be binding 
upon, the successors, assigns, heirs, executors and administrators of the 
parties hereto.

               (d)     Entire Agreement; Amendment.  This Agreement and the 
other documents delivered pursuant hereto at the Closing constitute the full 
and entire understanding and agreement between the parties with regard to the 
subjects hereof and thereof, and no party shall be liable or bound to any 
other party in any manner by any warranties, representations or covenants 
except as specifically set forth herein or therein.  Except as expressly 
provided herein, neither this Agreement nor any term hereof may be amended, 
waived, discharged or terminated other than by a written instrument signed by 
either (i) the party against whom enforcement of any such amendment, waiver, 
discharge or termination is sought or (ii) the Company and the Holders 
holding a majority of the then outstanding New Securities.

               (e)     Counterparts.  This Agreement may be executed in any 
number of counterparts, each of which shall be enforceable against the 
parties actually executing such counterparts, and all of which together shall 
constitute one instrument.

               (f)     Severability.  In the event that any provision of this 
Agreement becomes or is declared by a court of competent jurisdiction to be 
illegal, unenforceable or void, this Agreement shall continue in full force 
and effect without such provision; provided that no such severability shall 
be effective if it materially changes the economic benefit of this Agreement 
to any party.

               (g)     Titles and Subtitles.  The titles and subtitles used 
in this Agreement are used for convenience only and are not considered in 
construing or interpreting this Agreement.

               (h)     Benefits of Agreement.  Nothing in this Agreement, 
express or implied, shall give to any person, other than the parties hereto 
and their successors hereunder any benefit or any legal or equitable right,

CERTIFICATE OF DESIGNATION OF RIGHTS, PREFERENCES AND
PRIVILEGES OF SERIES A-2 PREFERRED STOCK

OF

SUPERCONDUCTOR TECHNOLOGIES INC.


Pursuant to Section 151 of the General Corporation Law
of the State of Delaware

     I, Peter Thomas, the Chief Executive Officer of Superconductor 
Technologies, Inc., a corporation organized and existing under the General 
Corporation Law of the State of Delaware (the "Corporation"), in accordance 
with the provisions of Section 103 thereof, DO HEREBY CERTIFY:
     That pursuant to the authority conferred upon the Board of Directors by 
the Amended and Restated Certificate of Incorporation of the Corporation, the 
Board of Directors on February 4, 1999 adopted the following resolution 
creating a series of 64,584 shares of Preferred Stock designated as Series 
A-2 Preferred Stock:

     RESOLVED: That pursuant to the authority vested in the Board of 
Directors of the Corporation by the Amended and Restated Certificate
of Incorporation, the Board of Directors does hereby provide for the issue
of a series of Preferred Stock, $0.001 par value, of the Corporation, to be
designated Series A-2 Preferred Stock (the "Series A-2 Preferred"), consisting
of 64,584 shares and to the extent that the designations, powers, preferences
and relative and other special rights and the qualifications, limitations and
 restrictions of the Series A-2 Preferred are not stated and expressed in the
Amended and Restated Certificate of Incorporation, does hereby fix and
herein state and express such designations, powers, preferences and relative
and other special rights and the qualifications, limitations and restrictions
thereof, as follows (all terms used herein which are defined in the Amended
and Restated Certificate of Incorporation shall be deemed to have the meanings
 provided therein):

          SECTION 1.     Designation and Amount.  The shares of such series 
shall be designated as "Series A-2 Preferred", par value $0.001 per share, 
and the number of shares constituting such series shall be 64,584.

          SECTION 2.     Rank.  Except as provided in Section 8, the Series 
A-2 Preferred Stock shall rank (i) prior to the Corporation's common stock, 
par value $.001 per share (the "Common Stock"); (ii) pari passu with the 
Series A-3 Preferred Stock, the Series B-1 Preferred Stock, and with any 
class or series of capital stock of the Corporation hereafter created 
specifically 
ranking, by its terms, on parity with the Series A-2 Preferred Stock; and 
(iii) junior to any class or series of capital stock of the Corporation 
hereafter created specifically ranking, by its terms, senior to the Series 
A-2 Preferred Stock, in each case as to distribution of assets upon 
liquidation, 
dissolution or winding up of the Corporation, whether voluntary or 
involuntary.

          SECTION 3.     Dividends.  The holders of shares of Series A-2 
Preferred shall be entitled to receive dividends, out of funds legally 
available therefor, payable in preference and priority to any payment of any 
dividend on Common Stock of the Corporation, at the rate of $3.60 per share 
(adjusted for any recapitalization, stock combinations, stock dividends, 
stock splits and the like (a "Recapitalization")) per annum for the Series 
A-2 
Preferred, provided however that in the event Stockholder Approval (as 
defined in Section 6(h)) is not obtained, then effective as of March 26, 1998, 
the 
$3.60 dividend amount shall be increased to $12.00 per share (as adjusted for 
Recapitalizations).  Such dividends shall be cumulative, accrue daily 
(beginning March 26, 1998) and be paid quarterly, in cash or as an addition 
to the Series A-2 Liquidation Preference (as defined below).  No dividend 
shall 
be paid on the Common Stock in any year, other than dividends payable solely 
in Common Stock, until all dividends due and payable on the Preferred Stock 
have been declared and paid, and then such dividends on the Common Stock 
shall not be in excess of the dividends paid on the Preferred Stock unless 
the 
amount of such excess is also paid on the Preferred Stock on an as-converted 
per share basis.

          SECTION 4.     Liquidation Preference.  In the event of any 
liquidation, dissolution or winding up of the Corporation, either voluntary 
or involuntary (a "Liquidation Event"), distributions to the stockholders of 
the 
Corporation shall be made in the following manner:

               (a)     The holders of Series A-2 Preferred shall be entitled 
to receive, on a pari passu basis with the holders of Series A-3, Series B-1 
and any other series of Preferred Stock ranked pari passu with Series A-2 
Preferred Stock but prior and in preference to any distribution of any of the 
assets or surplus funds of the Corporation to the holders of any series of 
Preferred Stock junior to Series A-2 Preferred Stock or holders of the Common 
Stock by reason of their ownership of such stock, an amount per share equal 
to the sum  (the "Series A-2 Liquidation Preference") of (i) $60.00 for each 
share of Series A-2 Preferred then held by them, adjusted for any 
Recapitalizations with respect to such shares and (ii) an amount equal to all 
unpaid dividends on the Series A-2 Preferred held by them; provided, however, 
in the event of a Liquidation Event pursuant to Section 4(b) below that is 
consummated on or before March 26, 2001, the Series A-2 Liquidation 
Preference shall be the greater of (i) $72.00 or (ii) $60.00 plus all accrued
dividends for each share of Series A-2 Preferred, adjusted for any 
Recapitalizations.  
If the assets and funds thus distributed among the holders of the Preferred 
Stock shall be insufficient to permit the payment to such holders of their 
full preferential amount, then the entire assets and funds of the Corporation 
legally available for distribution shall be distributed ratably among the 
holders of the Preferred Stock on a pari passu basis in proportion to the 
aggregate preferential amount of shares of Preferred Stock outstanding as of 
the date of the distribution upon the occurrence of such event.  After 
payment has been made to the holders of the Preferred Stock of the full 
preferential 
amount to which they shall be entitled, the holders of the Common Stock shall 
be entitled to share ratably in the remaining assets, based on the number of 
shares of Common Stock held.

               (b)     For purposes of this Section 4, a merger or 
consolidation of the Corporation with or into any other corporation or 
corporations, or the merger of any other corporation or corporations into the 
Corporation, or the sale of all or substantially all of the assets of the 
Corporation, or any other corporate reorganization, in which consolidation, 
merger, sale of assets or reorganization the stockholders of the Corporation 
receive distributions in cash or securities of another corporation or 
corporations as a result of such consolidation, merger, sale of assets or 
reorganization, shall be treated as a Liquidation Event unless the 
stockholders of this Corporation immediately prior to such consolidation, 
merger, sale of assets or reorganization hold or control more than fifty 
percent (50%) of the voting equity securities of the successor or surviving 
corporation immediately following such consolidation, merger, sale of assets 
or reorganization, in which case such consolidation, merger, sale of assets 
or reorganization shall not be treated as a Liquidation Event.

          SECTION 5.     Voting Rights.  Except as otherwise required by law, 
the Amended and Restated Certificate of Incorporation or Bylaws of the 
Corporation or this Certificate of Designation, the holder of each share of 
Common Stock issued and outstanding shall have one vote and the holder of 
each share of Preferred Stock shall be entitled to the number of votes equal 
to 
the number of shares of Common Stock into which such share of Preferred Stock 
could be converted, subject to the limits in Section 6(h) below, at the 
record date for determination of the stockholders entitled to vote on such 
matters, 
or, if no such record date is established, at the date such vote is taken or 
any written consent of stockholders is solicited, such votes to be counted 
together with all other shares of stock of the Corporation having general 
voting power and not separately as a class.  Holders of Common Stock and 
Preferred Stock shall be entitled to notice of any stockholders' meeting in 
accordance with the Bylaws of the Corporation.  Fractional votes by the 
holders of Preferred Stock shall not, however, be permitted and any 
fractional voting rights shall (after aggregating all shares into which shares 
of 
Preferred Stock held by each holder could be converted) be rounded to the 
nearest whole number.

          SECTION 6.     Conversion.  The holders of Series A-2 Preferred 
have conversion rights as follows (the "Conversion Rights"):

               (a)     Right to Convert.  Subject to the limits set forth in 
Section 6(h) below, each share of Series A-2 Preferred shall be convertible, 
at the option of the holder thereof, at any time after the date of issuance 
of such share at the office of the Corporation or any transfer agent for the 
Series A-2 Preferred into such number of fully paid and nonassessable shares 
of Common Stock as is determined by dividing $60.00 by the Series A-2 
Conversion Price, determined as hereinafter provided, in effect at the time 
of conversion.  The price at which shares of Common Stock shall be 
deliverable 
upon conversion of shares of Series A-2 Preferred shall initially be $3.00 
with respect to each share of Series A-2 Preferred (the "Series A-2 
Conversion Price").  The initial Series A-2 Conversion Price shall be subject 
to 
adjustment as hereinafter provided.

               (b)     Automatic Conversion.  Subject to the limits set forth 
in Section 6(h) below, each share of Series A-2 Preferred shall automatically 
be converted into shares of Common Stock at the then effective Series A-2 
Conversion Price for such series upon the election of holders of at least a 
majority of the then outstanding shares of Series A-2 Preferred. 

               (c)     Mechanics of Conversion.  The mechanics of conversion 
set forth in this Section 6(c) are subject to the limits set forth in Section 
6(h) below.  No fractional shares of Common Stock shall be issued upon 
conversion of Series A-2 Preferred.  In lieu of any fractional shares to 
which the holder would otherwise be entitled, the Corporation shall pay cash
equal to such fraction multiplied by the then effective Series A-2 Conversion 
Price.  Before any holder of Series A-2 Preferred shall be entitled to 
convert the same into full shares of Common Stock and to receive certificates 
therefor, the holder shall surrender the certificate or certificates therefor, 
duly
endorsed, at the office of the Corporation or of any transfer agent for 
the Series A-2 Preferred, and shall give written notice to the Corporation at 
such office that the holder elects to convert the same; provided, however, 
that in the event of an automatic conversion pursuant to Section 6(b), the 
outstanding shares of Series A-2 Preferred shall be converted automatically 
without any further action by the holders of such shares and whether or not 
the certificates representing such shares are surrendered to the Corporation 
or its transfer agent and provided further, that the Corporation shall not be 
obligated to issue certificates evidencing the shares of Common Stock 
issuable upon such automatic conversion unless the certificates evidencing
such shares of Series A-2 Preferred are either delivered to the Corporation or 
its 
transfer agent as provided above, or the holder notifies the Corporation or 
its transfer agent that such certificates have been lost, stolen or destroyed 
and executes an agreement satisfactory to the Corporation to indemnify the 
Corporation from any loss incurred by it in connection with such 
certificates.  The Corporation shall, as soon as practicable after such 
delivery, or such agreement and indemnification in the case of a lost 
certificate, issue and deliver at such office to such holder of Series A-2 
Preferred, a certificate or certificates for the number of shares of Common 
Stock to which such holder shall be entitled as aforesaid and a check payable 
to the holder in the amount of any cash amounts payable as the result of a 
conversion into fractional shares of Common Stock.  Such conversion shall be 
deemed to have been made immediately prior to the close of business on the 
date of such surrender of the shares of Series A-2 Preferred to be converted, 
or in the case of automatic conversion then on the date of election by a 
majority of the then outstanding shares of Series A-2 Preferred, and the 
person or persons entitled to receive the shares of Common Stock issuable 
upon such conversion shall be treated for all purposes as the record holder 
or 
holders of such shares of Common Stock on such date.

               (d)     (1)     Adjustment of Conversion Price of Series A-2 
Preferred Stock.  The Series A-2 Conversion Price shall be subject to 
adjustment from time to time as follows:

                              (i)     Adjustments for Subdivisions, 
Combinations or
Consolidation of Common Stock.  In the event the outstanding 
shares of Common Stock shall be subdivided by stock split, stock dividends or 
otherwise, into a greater number of shares of Common Stock, the Series A-2 
Conversion Price then in effect shall, concurrently with the effectiveness of 
such subdivision, be proportionately decreased.  In the event the outstanding 
shares of Common Stock shall be combined or consolidated, by reclassification 
or otherwise, into a lesser number of shares of Common Stock, the Series A-2 
Conversion Price then in effect shall, concurrently with the effectiveness of 
such combination or consolidation, be proportionately increased.

                              (ii)     Adjustments for Stock Dividends and 
Other Distributions.  In the event the Corporation at any time or from time 
to time makes, or fixes a record date for the determination of holders of 
Common 
Stock entitled to receive any distribution (excluding any repurchases of 
securities by the Corporation not made on a pro rata basis from all holders 
of any class of the Corporation's securities) payable in property or in 
securities of the Corporation other than shares of Common Stock, and other 
than as otherwise adjusted in this Section 6 or as provided in Section 3, 
then and in each such event the holders of Series A-2 Preferred shall receive 
at 
the time of such distribution, the amount of property or the number of 
securities of the Corporation that they would have received had their Series 
A-2 Preferred been converted into Common Stock on the date of such event.

                              (iii)     Adjustments for Reclassification, 
Exchange and Substitution.  Except as provided in Section 3 upon any 
liquidation, dissolution or winding up of the Corporation, if the Common 
Stock issuable upon conversion of the Series A-2 Preferred shall be changed 
into 
the same or a different number of shares of any other class or classes of 
stock, 
whether by capital reorganization, reclassification or otherwise (other than 
a subdivision or combination of shares provided for above), each share of 
Series A-2 Preferred shall thereafter be convertible into the number of shares 
of 
stock or other securities or property to which a holder of the number of 
shares of Common Stock of the Corporation deliverable upon conversion of such 
share of Series A-2 Preferred shall have been entitled upon such 
reorganization or reclassification.

                    (2)     Adjustments of Series A-2 Conversion Price for 
Diluting Issues.  In addition to the adjustment of the Series A-2 Conversion 
Price provided in Section 6(d)(1) above, the Series A-2 Conversion Price 
shall be subject to further adjustment from time to time as follows:

                              (i)     Special Definitions.  For purposes of 
this Section 6(d)(2), the following definitions shall apply:

                                   (1)     "Options" shall mean rights, 
options or warrants to subscribe for, purchase or otherwise acquire either 
Common Stock or Convertible Securities.

                                   (2)     "Original Issue Date" shall mean 
March 26, 1998.

                                   (3)     "Convertible Securities" shall 
mean 
securities convertible into or exchangeable for Common Stock.

                                   (4)     "Additional Shares of Common 
Stock" 
shall mean all shares of Common Stock issued (or, pursuant to Section 
6(d)(2)(iii), deemed to be issued) by the Corporation after the Original 
Issue 
Date other than shares of Common Stock issued or issuable:

                                        (A)     upon conversion of shares of 
the Preferred Stock;

                                        (B)     to officers, directors and 
employees of, and consultants to, the Corporation pursuant to plans and 
arrangements approved by the Board of Directors;

                                        (C)     as a dividend or other 
distribution on the Preferred Stock or pursuant to clause (i), (ii) or (iii) 
of Section 6(d)(1);

                                        (D)     upon the exercise of options 
issued prior to the Original Issue Date; 

                                        (E)     to research or development 
collaborators or  to banks or other institutional lendors or lessors in 
connection with capital asset leases or borrowings for the acquisition of 
capital assets, pursuant to any arrangement approved by the Board of 
Directors; 
                                        (F)     upon exercise of warrants 
outstanding on the  Original Issue Date or warrants to be issued pursuant to 
agreements outstanding on the Original Issue Date, including without 
limitation the following warrants:  warrant, dated as of November 22, 1997, 
the warrant dated as of December 21, 1998, warrants issued or issuable 
pursuant to the Letter Agreement between the Company and Tanner Unman 
Securities, Inc., dated as August 10, 1998, the warrants issued or issuable 
pursuant to the Exchange Agreement, any additional warrants to be issued 
pursuant to the Securities Purchase Agreement dated as of September 2, 1998, 
and any Preferred Stock purchase agreement entered into before Stockholder 
Approval (as defined below);

                                        (G)     with the written approval of 
the holders of a majority of the outstanding Series A-2 Preferred; or

                                        (H)     by way of dividend or other 
distributions on securities referred to in clauses (A), (B), (C), (D), (E), 
(F) and (G) above.

                              (ii)     No Adjustment of Series A-2 Conversion 
Price.  No adjustment in the Series A-2 Conversion Price of a particular 
share of Series A-2 Preferred shall be made in respect of the issuance of 
Additional Shares of Common Stock unless the consideration per share for
an Additional Share of Common Stock issued or deemed to be issued by the
Corporation is less than the Series A-2 Conversion Price in effect on the date
of, and immediately prior to such issue, for such share of Series A-2 
Preferred.

                              (iii)     Deemed Issue of Additional Shares of 
Common Stock.

                                   (1)     Options and Convertible 
Securities.  Except as otherwise provided in Section 6(d)(2)(i) above, in the 
event the Corporation at any time or from time to time after the Original 
Issue Date shall issue any Options or Convertible Securities or shall fix a 
record date for the determination of any holders of any class of securities 
entitled to receive any such Options or Convertible Securities, then the 
maximum number of shares (as set forth in the instrument relating thereto 
without regard to any provisions contained therein for a subsequent 
adjustment of such number) of Common Stock issuable upon the exercise 
of such Options or, in the case of Convertible Securities and Options 
therefor,
the conversion or exchange of such Convertible Securities, shall be deemed to
be Additional Shares of Common Stock issued as of the time of such issue or, 
in case such a record date shall have been fixed, as of the close of business 
on
such record date, provided that Additional Shares of Common Stock shall not 
be deemed to have been issued unless the consideration per share (determined
pursuant to Section 6(d)(2)(v) below) of such Additional Shares of Common
Stock would be less than the Series A-2 Conversion Price in effect on the date
of and immediately prior to such issue, or such record date, as the case may 
be,
and provided further that in any such case in which additional shares of 
Common 
Stock are deemed to be issued:

                                        (A)     no further adjustment in the 
Series A-2 Conversion Price shall be made upon the subsequent issue of 
Convertible Securities or shares of Common Stock upon the exercise of such 
Options or conversion or exchange of such Convertible Securities;

                                        (B)     if such Options or 
Convertible Securities by their terms provide, with the passage of time or 
otherwise,
for any increase or decrease in the consideration payable to the Corporation, 
or 
increase or decrease in the number of shares of Common Stock issuable, upon 
the exercise, conversion or exchange thereof, the Series A-2 Conversion Price 
computed upon the original issue thereof (or upon the occurrence of a record 
date with respect thereto), and any subsequent adjustments based thereon, 
shall, upon any such increase or decrease becoming effective, be recomputed 
to reflect such increase or decrease insofar as it affects such Options or 
the 
rights of conversion or exchange under such Convertible Securities;

                                        (C)     upon the expiration of any 
such Options or any rights of conversion or exchange under such Convertible 
Securities which shall not have been exercised, the Series A-2 Conversion 
Price computed upon the original issue thereof (or upon the occurrence of a 
record date with respect thereto), and any subsequent adjustments based 
thereon, shall, upon such expiration, be recomputed as if:

                                             (I)     in the case of 
Convertible Securities or
Options for Common Stock, the only additional shares of Common Stock
 issued were shares of Common Stock, if any, actually issued 
upon the exercise of such Options or the conversion or exchange of such 
Convertible Securities, and the consideration received therefor was the 
consideration actually received by the Corporation for the issue of all such 
Options, whether or not exercised, plus the consideration actually received 
by the Corporation upon such exercise, or for the issue of all such 
Convertible 
Securities which were actually converted or exchanged, plus the additional 
consideration, if any, actually received by the Corporation upon such 
conversion or exchange, and

                                             (II)     in the case of Options 
for Convertible Securities, only the Convertible Securities, if any, actually 
issued upon the exercise thereof were issued at the time of issue of such 
Options and the consideration received by the Corporation for the Additional 
Shares of Common Stock deemed to have been then issued was the consideration 
actually received by the Corporation for the issue of all such Options, 
whether or not exercised, plus the consideration deemed to have been received 
by the Corporation upon the issue of the Convertible Securities with respect 
to which such Options were actually exercised;

                                        (D)     no readjustment pursuant to 
clause (B) or (C) above shall have the effect of increasing the Series A-2 
Conversion Price to an amount which exceeds the lower of (i) the Series A-2 
Conversion Price on the original adjustment date, or (ii) the Series A-2 
Conversion Price that would have resulted from any issuance of Additional 
Shares of Common Stock between the original adjustment date and such 
readjustment date; and

                                        (E)     in the case of any Options 
which expire by their terms not more than thirty (30) days after the date of 
issue thereof, no adjustment of the Series A-2 Conversion Price shall be made 
until the expiration or exercise of all such Options.

                              (iv)     Adjustment of Series A-2 Conversion 
Price Upon Issuance of Additional Shares of Common Stock.  In the event the 
Corporation shall issue Additional Shares of Common Stock (including 
Additional Shares of Common Stock deemed to be issued pursuant to Section 
6(d)(2)(iii), but excluding stock dividends, subdivisions or split-ups that 
are the subject of adjustment pursuant to Section 6(d)(i)) without 
consideration or for a consideration per share less than the Series A-2 
Conversion Price, in effect on the date of, and immediately prior to such 
issue, then and in such event, such Series A-2 Conversion Price shall be 
reduced, 
concurrently with such issue, to a price (calculated to the nearest cent) 
determined by multiplying such Series A-2 Conversion Price by a fraction, the 
numerator of which shall be the sum of (i) the number of shares of Common 
Stock outstanding immediately prior to such issue, (ii) the number of shares 
of Common Stock issuable upon conversion of the Preferred Stock outstanding 
immediately prior to such issue and (iii) the number of shares of Common 
Stock which the aggregate consideration received by the Corporation for the 
total 
number of Additional Shares of Common Stock so issued would purchase at such 
Series A-2 Conversion Price; and the denominator of which shall be the sum of 
(i) the number of shares of Common Stock outstanding immediately prior to 
such issue, (ii) the number of shares of Common Stock issuable upon conversion 
of 
the Preferred Stock outstanding immediately prior to such issue and (iii)  
the number of such Additional Shares of Common Stock so issued; and provided 
further that, for the purposes of this Section 6(d)(2)(iv), all shares of 
Common Stock issuable upon exercise of outstanding Options or conversion of 
outstanding Convertible Securities shall be deemed to be outstanding, and 
immediately after any Additional Shares of Common Stock are deemed issued 
pursuant to Section 6(d)(2)(iii), such Additional Shares of Common Stock 
shall be deemed to be outstanding.

                              (v)     Determination of Consideration.  For 
purposes of this Section 6(d)(2), the consideration received by the 
Corporation for the issue of any Additional Shares of Common Stock shall be 
computed as follows:

                                   (1)     Cash and Property:  Such 
consideration shall:

                                        (A)     insofar as it consists of 
cash, be computed at the
aggregate amount of cash received by the Corporation (excluding amounts paid
or payable for accrued interest or accrued dividends);

                                        (B)     insofar as it consists of 
property other than cash,
be computed at the fair value thereof at the time of such issue, as determined 
in
good faith by the Board of Directors; and

                                        (C)     in the event Additional 
Shares 
of Common Stock are issued together with other shares or securities or other 
assets of the Corporation for consideration which covers both, be the 
proportion of such consideration so received, computed as provided in clauses 
(A) and (B) above, as determined in good faith by the Board of Directors.

                              (2)     Options and Convertible Securities.  
The consideration per share received by the Corporation for Additional Shares 
of 
Common Stock deemed to have been issued pursuant to Section 6(d)(2)(iii)(1), 
relating to Options and Convertible Securities, shall be determined by 
dividing
                                   (x)     the total amount, if any, received 
or receivable by the Corporation as consideration for the issue of such 
Options or Convertible Securities, plus the minimum aggregate amount of 
additional consideration (as set forth in the instruments relating thereto, 
without regard to any provision contained therein for a subsequent adjustment 
of such consideration) payable to the Corporation upon the exercise of such 
Option or the conversion or exchange of such Convertible Securities, or in 
the case of Options for Convertible Securities, the exercise of such Options 
for 
Convertible Securities and the conversion or exchange of such Convertible 
Securities by

                                   (y)     the maximum number of shares of 
Common Stock (as set forth in the instruments relating thereto, without 
regard to any provision contained therein for a subsequent adjustment of such 
number) issuable upon the exercise of such Options or the conversion or 
exchange of 
such Convertible Securities.
               (e)     No Impairment.  Except as provided in Section 8, the 
Corporation will not, by amendment of its Amended and Restated Certificate of 
Incorporation or this Certificate of Designation or through any 
reorganization, transfer of assets, consolidation, merger, dissolution, issue 
or sale of securities or any other voluntary action, avoid or seek to avoid 
the observance or performance of any of the terms to be observed or performed 
hereunder by the Corporation but will at all times in good faith assist in 
the carrying out of all the provisions of this Section 6 and in the taking of 
all 
such action as may be necessary or appropriate in order to protect the 
Conversion Rights of the holders of the Series A-2 Preferred Stock against 
impairment.

               (f)     Certificate as to Adjustments.  Upon the occurrence of 
each adjustment or readjustment of the Series A-2 Conversion Price pursuant 
to this Section 6, the Corporation at its expense shall promptly compute such 
adjustment or readjustment in accordance with the terms hereof and furnish to 
each holder of Series A-2 Preferred a certificate setting forth such 
adjustment or readjustment and showing in detail the facts upon which such 
adjustment or readjustment is based.  The Corporation shall, upon the written 
request at any time of any holder of Series A-2 Preferred, furnish or cause 
to be furnished to such holder a like certificate setting forth (i) such 
adjustments and readjustments, (ii) the Series A-2 Conversion Price at the 
time in effect, and (iii) the number of shares of Common Stock and the 
amount, if any, of other property which at the time would be received upon 
the conversion of Series A-2 Preferred.

               (g)     Notices of Record Date.  In the event that the 
Corporation shall propose at any time:

                         (i)     to declare any dividend or distribution upon 
its Common Stock, whether in cash, property, stock or other securities, 
whether or not a regular cash dividend and whether or not out of earnings or 
earned surplus;

                         (ii)     to effect any reclassification or 
capitalization of its Common Stock outstanding involving a change in the 
Common Stock; or

                         (iii)     to merge or consolidate with or into any 
other person or entity, or sell, lease or convey all or substantially all its 
property or business, or to liquidate, dissolve or wind up;

then, in connection with each such event, the Corporation shall send to the 
holders of Series A-2 Preferred:

                              (1)     at least twenty (20) days' prior 
written notice of the date on which a record shall be taken for such 
dividend, 
distribution or subscription rights (and specifying the date on which the 
holders of Common Stock shall be entitled thereto) or for determining rights 
to vote in respect of the matters referred to in (ii) and (iii) above; and

                              (2)     in the case of the matters referred to 
in (ii) and (iii) above, at least twenty (20) days' prior written notice of 
the date when the same shall take place (and specifying the date on which the 
holders of Common Stock shall be entitled to exchange their Common Stock for 
securities or other property deliverable upon the occurrence of such event).

     Each such written notice shall be delivered personally or given by first 
class mail, postage prepaid, addressed to the holders of the Series A-2 
Preferred at the address for each such holder as shown on the books of the 
Corporation.  The above written notice requirement may be waived by the 
holders of a majority of the then outstanding Series A-2 Preferred Stock.

               (h)          Limits on Conversion. Notwithstanding anything 
herein to the contrary, the Series A-2, Series A-3, and Series B-1 Preferred 
Stock of the Corporation and any additional shares of Preferred Stock issued 
by the Corporation prior to Stockholder Approval (as defined below), and the 
outstanding warrants to purchase Common Stock of the Corporation (issued or 
issuable to holders of such shares of Preferred Stock pursuant to agreements 
outstanding as of February 26, 1999 or entered into prior to Stockholder 
Approval) (collectively, the "Securities") shall not be convertible into or 
exercisable for (as the case may be) shares of Common Stock in excess of 
1,533,709 shares (as adjusted for Recapitalizations and the like) (the "19.9% 
Cap" or the "Allowed Conversion Shares"), unless the Corporation has received 
stockholder approval to eliminate such 19.9% Cap at a duly held meeting of 
the stockholders in calendar 1999 (the  "Stockholder Approval").  Until 
Stockholder Approval has been obtained (or, if Stockholder Approval  is not 
obtained, then continuing thereafter) the 19.9% Cap shall apply and each 
holder of Securities (each a "Holder") shall have the right to convert its 
Preferred Stock or exercise its warrants only up to its pro rata portion of 
the Allowed Conversion Shares.  A Holder may waive in writing its right to 
convert or exercise (or transfer to another Holder) its pro rata portion of 
the Allowed Conversion Shares.  In the event that a Holder converts or 
exercises its Securities, then the number of Allowed Conversion Shares will 
be reduced by such amount.

          SECTION 7.     Status of Converted Stock.  In case any shares of 
Series A-2 Preferred shall be repurchased or converted pursuant to Section 6, 
the shares so repurchased or converted shall be canceled and shall not be 
issued by the Corporation as Series A-2 Preferred and this Certificate of 
Designation shall be appropriately amended to effect the corresponding 
reduction in the Corporation's authorized Series A-2 Preferred.

          SECTION 8.     Covenants.  In addition to any other rights provided 
by law, so long as at least twenty-five percent (25%) of the authorized 
Series A-2 Preferred shall be outstanding, the Corporation shall not, without 
first 
obtaining the affirmative vote or written consent of the holders of not less 
than a majority of the outstanding shares of Series A-2 Preferred:

               (a)     amend or repeal any provision of the Corporation's 
Amended or Restated Certificate of Incorporation, certificates of designation 
or Bylaws if such action would materially and adversely alter or change the 
preferences, rights, privileges or powers of, or the restrictions provided 
for the benefit of, the Series A-2 Preferred; or 

               (b)     authorize or issue shares of any class or series of 
stock having any preference or priority as to dividends or assets superior to 
or on parity with any such preference or priority of the Series A-2 Preferred.

     IN WITNESS WHEREOF, Superconductor Technologies Inc. has caused this 
Certificate to be signed by Peter Thomas, its Chief Executive Officer, this 
__th day of February, 1999.

EXHIBIT C

CERTIFICATE OF DESIGNATION OF RIGHTS, PREFERENCES AND
PRIVILEGES OF SERIES A-3 PREFERRED STOCK

OF
SUPERCONDUCTOR TECHNOLOGIES INC.

Pursuant to Section 151 of the General Corporation Law
of the State of Delaware
     I, Peter Thomas, the Chief Executive Officer of Superconductor 
Technologies, Inc., a corporation organized and existing under the General 
Corporation Law of the State of Delaware (the "Corporation"), in accordance 
with the provisions of Section 103 thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by 
the Amended and Restated Certificate of Incorporation of the Corporation, the 
Board of Directors on February 4, 1999 adopted the following resolution 
creating a series of 12,500 shares of Preferred Stock designated as Series 
A-3 
Preferred Stock:

     RESOLVED: That pursuant to the authority vested in the Board of 
Directors of the Corporation by the Amended and Restated Certificate of 
Incorporation, the Board of Directors does hereby provide for the issue of a 
series of Preferred Stock, $0.001 par value, of the Corporation, to be 
designated 
Series A-3 Preferred Stock ("Series A-3 Preferred"), consisting of 12,500 
shares 
and to the extent that the designations, powers, preferences and relative and 
other special rights and the qualifications, limitations and restrictions of 
the Series A-3 Preferred are not stated and expressed in the Amended and 
Restated Certificate of Incorporation, does hereby fix and herein state and 
express such designations, powers, preferences and relative and other special 
rights and the qualifications, limitations and restrictions thereof, as 
follows (all terms used herein which are defined in the Amended and Restated 
Certificate of Incorporation shall be deemed to have the meanings provided 
therein):

          SECTION      (1)     Designation and Amount.  The shares of such 
series shall be designated as "Series A-3 Preferred", par value $0.001 per 
share, and the number of shares constituting such series shall be 12,500.

          SECTION 2.     Rank.  Except as provided in Section 8, the Series 
A-3 Preferred Stock shall rank (i) prior to the Corporation's common stock, 
par value $.001 per share (the "Common Stock"); (ii) pari passu with the 
Series A-2 Preferred Stock, the Series B-1 Preferred Stock, and with any 
class or series of capital stock of the Corporation hereafter created 
specifically 
ranking, by its terms, on parity with the Series A-3 Preferred Stock; and 
(iii) 
junior to any class or series of capital stock of the Corporation hereafter 
created specifically ranking, by its terms, senior to the Series A-3 
Preferred Stock, in each case as to distribution of assets upon liquidation, 
dissolution or winding up of the Corporation, whether voluntary or 
involuntary.

          SECTION 3.     Dividends.  The holders of shares of Series A-3 
Preferred shall be entitled to receive dividends, out of funds legally 
available therefor, payable in preference and priority to any payment of any 
dividend on Common Stock of the Corporation, at the rate of $4.80 per share 
(adjusted for any recapitalization, stock combinations, stock dividends, 
stock splits and the like (a "Recapitalization")) per annum for the Series 
A-3 
Preferred, provided however, that in the event Stockholder Approval (as 
defined in Section 6(h)) is not obtained, then effective as of August 11, 
1998, the $4.80 dividend shall be increased to $16.00 per share (as adjusted 
for Recapitalizations).  Such dividends shall be cumulative, accrue daily 
(beginning August 11, 1998) and be paid quarterly in cash or as an addition 
to the Series A-3 Liquidation Preference (as defined below).  No dividend 
shall 
be paid on the Common Stock in any year, other than dividends payable solely 
in Common Stock, until all dividends due and payable on the Preferred Stock 
have been declared and paid, and then such dividends on the Common Stock 
shall not be in excess of the dividends paid on the Preferred Stock unless 
the 
amount of such excess is also paid on the Preferred Stock on an as-converted 
per share basis.

          SECTION 4.     Liquidation Preference.  In the event of any 
liquidation, dissolution or winding up of the Corporation, either voluntary 
or involuntary (a "Liquidation Event"), distributions to the stockholders of 
the 
Corporation shall be made in the following manner:

               (c)     The holders of Series A-3 Preferred shall be entitled 
to receive, on a pari passu basis with the holders of Series A-2, Series B-1 
and any series of Preferred Stock ranked pari passu with Series A-3 Preferred 
Stock, but prior and in preference to any distribution of any of the assets 
or surplus funds of the Corporation to the holders of any series of Preferred 
Stock ranked junior to series A-3 Preferred Stock or holders of the Common 
Stock by reason of their ownership of such stock, an amount per share equal 
to the sum  (the "Series A-3 Liquidation Preference") of (i) $80.00 for each 
share of Series A-3 Preferred (the "Original Purchase Price") then held by 
them, adjusted for any Recapitalizations with respect to such shares and, 
(ii) an amount equal to all unpaid dividends on the Series A-3 Preferred held 
by 
them; provided however, in the event of a Liquidation Event pursuant to 
Section 4(b) below that is consummated on or before March 26, 2001, the 
Liquidation Preference shall be the greater of (i) $96.00 or (ii) $80.00 plus 
all accrued dividends for each share of Series A-3 Preferred, adjusted for 
any Recapitalizations.  If the assets and funds thus distributed among the 
holders of the Preferred Stock shall be insufficient to permit the payment to 
such 
holders of their full preferential amount, then the entire assets and funds 
of the Corporation legally available for distribution shall be distributed 
ratably among the holders of the Preferred Stock on a pari passu basis in 
proportion to the aggregate preferential amount of shares of Preferred Stock 
outstanding as of the date of the distribution upon the occurrence of such 
event.  After payment has been made to the holders of the Preferred Stock of 
the full preferential amounts to which they shall be entitled, the holders of 
the Common Stock shall be entitled to share ratably in the remaining assets, 
based on the number of shares of Common Stock held.

               (d)     For purposes of this Section 4, a merger or 
consolidation of the Corporation with or into any other corporation or 
corporations, or the merger of any other corporation or corporations into the 
Corporation, or the sale of all or substantially all of the assets of the 
Corporation, or any other corporate reorganization, in which consolidation, 
merger, sale of assets or reorganization the stockholders of the Corporation 
receive distributions in cash or securities of another corporation or 
corporations as a result of such consolidation, merger, sale of assets or 
reorganization, shall be treated as a Liquidation Event unless the 
stockholders of this Corporation immediately prior to such consolidation, 
merger, sale of assets or reorganization hold or control more than fifty 
percent (50%) of the voting equity securities of the successor or surviving 
corporation immediately following such consolidation, merger, sale of assets 
or reorganization, in which case such consolidation, merger, sale of assets 
or reorganization shall not be treated as a Liquidation Event.

          SECTION 5.     Voting Rights.  Except as otherwise required by law, 
the Amended and Restated Certificate of Incorporation or Bylaws of the 
Corporation or this Certificate of Designation, the holder of each share of 
Common Stock issued and outstanding shall have one vote and the holder of 
each share of Preferred Stock shall be entitled to the number of votes equal 
to 
the number of shares of Common Stock into which such share of Preferred Stock 
could be converted, subject to the limits set forth in Section 6(h) below, at 
the record date for determination of the stockholders entitled to vote on 
such matters, or, if no such record date is established, at the date such vote 
is 
taken or any written consent of stockholders is solicited, such votes to be 
counted together with all other shares of stock of the Corporation having 
general voting power and not separately as a class.  Holders of Common Stock 
and Preferred Stock shall be entitled to notice of any stockholders' meeting 
in accordance with the Bylaws of the Corporation.  Fractional votes by the 
holders of Preferred Stock shall not, however, be permitted and any 
fractional voting rights shall (after aggregating all shares into which shares 
of 
Preferred Stock held by each holder could be converted) be rounded to the 
nearest whole number.

          SECTION 6.     Conversion.  The holders of Series A-3 Preferred 
have conversion rights as follows (the "Conversion Rights"):

               (a)     Right to Convert.  Subject to the limits set forth in 
Section 6(h) below, each share of Series A-3 Preferred shall be convertible, 
at the option of the holder thereof, at any time after the date of issuance 
of 
such share at the office of the Corporation or any transfer agent for the 
Series A-3 Preferred into such number of fully paid and nonassessable shares 
of Common Stock as is determined by dividing $80.00 by the Series A-3 
Conversion Price, determined as hereinafter provided, in effect at the time 
of conversion.  The price at which shares of Common Stock shall be 
deliverable 
upon conversion of shares of Series A-3 Preferred shall initially be $4.00 
with respect to each share of Series A-3 Preferred (the "Series A-3 
Conversion Price").  The initial Series A-3 Conversion Price shall be subject 
to 
adjustment as hereinafter provided.

               (b)     Automatic Conversion.  Subject to the limits set forth 
in Section 6(h) below, each share of Series A-3 Preferred shall automatically 
be converted into shares of Common Stock at the then effective Series A-3 
Conversion Price for such series upon the election of holders of at least a 
majority of the then outstanding shares of Series A-3 Preferred. 

               (e)     Mechanics of Conversion.  The mechanics of conversion 
set forth in this Section 6(c) are subject to the limits set forth in Section 
5(h) below.  No fractional shares of Common Stock shall be issued upon 
conversion of Series A-3 Preferred.  In lieu of any fractional shares to 
which the holder would otherwise be entitled, the Corporation shall pay cash 
equal 
to such fraction multiplied by the then effective Series A-3 Conversion 
Price.  Before any holder of Series A-3 Preferred shall be entitled to 
convert the same into full shares of Common Stock and to receive certificates 
therefor, the holder shall surrender the certificate or certificates 
therefor, duly endorsed, at the office of the Corporation or of any transfer 
agent for 
the Series A-3 Preferred, and shall give written notice to the Corporation at 
such office that the holder elects to convert the same; provided, however, 
that in the event of an automatic conversion pursuant to Section 6(b), the 
outstanding shares of Series A-3 Preferred shall be converted automatically 
without any further action by the holders of such shares and whether or not 
the certificates representing such shares are surrendered to the Corporation 
or its transfer agent and provided further, that the Corporation shall not be 
obligated to issue certificates evidencing the shares of Common Stock 
issuable upon such automatic conversion unless the certificates evidencing 
such shares 
of Series A-3 Preferred are either delivered to the Corporation or its 
transfer agent as provided above, or the holder notifies the Corporation or 
its transfer agent that such certificates have been lost, stolen or destroyed 
and executes an agreement satisfactory to the Corporation to indemnify the 
Corporation from any loss incurred by it in connection with such 
certificates.  The Corporation shall, as soon as practicable after such 
delivery, or such agreement and indemnification in the case of a lost 
certificate, issue and deliver at such office to such holder of Series A-3 
Preferred, a certificate or certificates for the number of shares of Common 
Stock to which such holder shall be entitled as aforesaid and a check payable 
to the holder in the amount of any cash amounts payable as the result of a 
conversion into fractional shares of Common Stock.  Such conversion shall be 
deemed to have been made immediately prior to the close of business on the 
date of such surrender of the shares of Series A-3 Preferred to be converted, 
or in the case of automatic conversion then on the date of election by a 
majority of the then outstanding shares of Series A-3 Preferred, and the 
person or persons entitled to receive the shares of Common Stock issuable 
upon such conversion shall be treated for all purposes as the record holder 
or 
holders of such shares of Common Stock on such date.

               (f)     (1)     Adjustment of Conversion Price of Series A-3 
Preferred Stock.  The Series A-3 Conversion Price shall be subject to 
adjustment from time to time as follows:

                              (i)     Adjustments for Subdivisions, 
Combinations or Consolidation of Common Stock.  In the event the outstanding 
shares of Common Stock shall be subdivided by stock split, stock dividends or 
otherwise, into a greater number of shares of Common Stock, the Series A-3 
Conversion Price then in effect shall, concurrently with the effectiveness of 
such subdivision, be proportionately decreased.  In the event the outstanding 
shares of Common Stock shall be combined or consolidated, by reclassification 
or otherwise, into a lesser number of shares of Common Stock, the Series A-3 
Conversion Price then in effect shall, concurrently with the effectiveness of 
such combination or consolidation, be proportionately increased.

                              (ii)     Adjustments for Stock Dividends and 
Other Distributions.  In the event the Corporation at any time or from time 
to time makes, or fixes a record date for the determination of holders of 
Common 
Stock entitled to receive any distribution (excluding any repurchases of 
securities by the Corporation not made on a pro rata basis from all holders 
of any class of the Corporation's securities) payable in property or in 
securities of the Corporation other than shares of Common Stock, and other 
than as otherwise adjusted in this Section 6 or as provided in Section 3, 
then and in each such event the holders of Series A-3 Preferred shall receive 
at 
the time of such distribution, the amount of property or the number of 
securities of the Corporation that they would have received had their Series 
A-3 Preferred been converted into Common Stock on the date of such event.

                              (iii)     Adjustments for Reclassification, 
Exchange and Substitution.  Except as provided in Section 4 upon any 
liquidation, dissolution or winding up of the Corporation, if the Common 
Stock issuable upon conversion of the Series A-3 Preferred shall be changed
into the 
same or a different number of shares of any other class or classes of stock, 
whether by capital reorganization, reclassification or otherwise (other than 
a subdivision or combination of shares provided for above), each share of 
Series A-3 Preferred shall thereafter be convertible into the number of shares 
of 
stock or other securities or property to which a holder of the number of 
shares of Common Stock of the Corporation deliverable upon conversion of such 
share of Series A-3 Preferred shall have been entitled upon such 
reorganization or reclassification.

               (d)     (2)     Adjustments of Series A-3 Conversion Price for 
Diluting Issues.  In addition to the adjustment of the Series A-3 Conversion 
Price provided in Section 6(d)(1) above, the Series A-3 Conversion Price 
shall be subject to further adjustment from time to time as follows:

                              (i)     Special Definitions.  For purposes of 
this Section 6(d)(2), the following definitions shall apply:

                                   (1)     "Options" shall mean rights, 
options or warrants to subscribe for, purchase or otherwise acquire either 
Common Stock or Convertible Securities.

                                   (2)     "Original Issue Date" shall mean 
August 11, 1998.

                                   (3)     "Convertible Securities" shall 
mean 
securities convertible into or exchangeable for Common Stock.

                                   (4)     "Additional Shares of Common 
Stock" shall mean all shares of Common Stock issued (or, pursuant to Section 
6(d)(2)(iii), deemed to be issued) by the Corporation after the Original 
Issue Date other than shares of Common Stock issued or issuable:

                                        (A)     upon conversion of shares of 
the Preferred Stock;

                                        (B)     to officers, directors and 
employees of, and consultants to, the Corporation pursuant to plans and 
arrangements approved by the Board of Directors;

                                        (C)     as a dividend or other 
distribution on the Preferred Stock or pursuant to clause (i), (ii) or (iii) 
of Section 6(d)(1);

                                        (D)     upon the exercise of options 
issued prior to the Original Issue Date; 
                                        (E)     to research or development 
collaborators or  to banks or other institutional lendors or lessors in 
connection with capital asset leases or borrowings for the acquisition of 
capital assets, pursuant to any arrangement approved by the Board of 
Directors; 

                                        (F)     upon exercise of warrants 
outstanding on the  Original Issue Date or warrants to be issued pursuant to 
agreements outstanding on the Original Issue Date, including without 
limitation the following warrants:  warrant, dated as of November 22, 1997, 
the warrant dated as of December 21, 1998 and warrants issued or issuable 
pursuant to the Letter Agreement between the Company and Tanner Unman 
Securities, Inc., dated as August 10, 1998, warrants issued or issuable 
pursuant to the Exchange Agreement, any additional warrants to be issued 
pursuant to the Securities Purchase Agreement dated as of September 2, 1998, 
and any Preferred Stock purchase agreement entered into before Stockholder 
Approval (as defined below);

                                        (G)     with the written approval of 
the holders of a majority of the outstanding Series A-3 Preferred; or
     
                                        (H)     by way of dividend or other 
distributions on securities referred to in clauses (A), (B), (C), (D) (E), 
(F) and (G) above.

                              (ii)     No Adjustment of Series A-3 Conversion 
Price.  No adjustment in the Series A-3 Conversion Price of a particular 
share of Series A-3 Preferred shall be made in respect of the issuance of 
Additional Shares of Common Stock unless the consideration per share for an
Additional Share of Common Stock issued or deemed to be issued by the 
Corporation is less than the Series A-3 Conversion Price in effect on the date
of, and immediately prior to such issue, for such share of Series A-3 
Preferred.

                              (iii)     Deemed Issue of Additional Shares of 
Common Stock.

                                   (1)     Options and Convertible 
Securities.  Except as otherwise provided in Section 6(d)(2)(i) above, in the 
event the Corporation at any time or from time to time after the Original 
Issue Date shall issue any Options or Convertible Securities or shall fix a 
record date for the determination of any holders of any class of securities 
entitled to receive any such Options or Convertible Securities, then the 
maximum number of shares (as set forth in the instrument relating thereto 
without regard to any provisions contained therein for a subsequent 
adjustment of such number) of Common Stock issuable upon the exercise of
such Options or, in the case of Convertible Securities and Options therefor, 
the
conversion or exchange of such Convertible Securities, shall be deemed to be
Additional Shares of Common Stock issued as of the time of such issue or, in
case such a record date shall have been fixed, as of the close of business on 
such
 record date, provided that Additional Shares of Common Stock shall not be 
deemed to have been issued unless the consideration per share (determined 
pursuant to Section 6(d)(2)(v) below) of such Additional Shares of Common
Stock would be less than the Series A-3 Conversion Price in effect on the date 
of
and immediately prior to such issue, or such record date, as the case may be, 
and 
provided further that in any such case in which additional shares of Common 
Stock are deemed to be issued:

                                        (A)     no further adjustment in the 
Series A-3 Conversion Price shall be made upon the subsequent issue of 
Convertible Securities or shares of Common Stock upon the exercise of such 
Options or conversion or exchange of such Convertible Securities;

                                        (B)     if such Options or 
Convertible Securities by their terms provide, with the passage of time or 
otherwise,
for any increase or decrease in the consideration payable to the Corporation, 
or 
increase or decrease in the number of shares of Common Stock issuable, upon 
the exercise, conversion or exchange thereof, the Series A-3 Conversion Price 
computed upon the original issue thereof (or upon the occurrence of a record 
date with respect thereto), and any subsequent adjustments based thereon, 
shall, upon any such increase or decrease becoming effective, be recomputed 
to reflect such increase or decrease insofar as it affects such Options or 
the 
rights of conversion or exchange under such Convertible Securities;

                                        (C)     upon the expiration of any 
such Options or any rights of conversion or exchange under such Convertible 
Securities which shall not have been exercised, the Series A-3 Conversion 
Price computed upon the original issue thereof (or upon the occurrence of a 
record date with respect thereto), and any subsequent adjustments based 
thereon, shall, upon such expiration, be recomputed as if:

                                             (I)     in the case of 
Convertible Securities or Options for Common Stock, the only additional 
shares of Common Stock issued were shares of Common Stock, if any, actually
 issued upon the exercise of such Options or the conversion or exchange of 
such 
Convertible Securities, and the consideration received therefor was the 
consideration actually received by the Corporation for the issue of all such 
Options, whether or not exercised, plus the consideration actually received 
by the Corporation upon such exercise, or for the issue of all such 
Convertible 
Securities which were actually converted or exchanged, plus the additional 
consideration, if any, actually received by the Corporation upon such 
conversion or exchange, and

                                             (II)     in the case of Options 
for Convertible Securities, only the Convertible Securities, if any, actually 
issued upon the exercise thereof were issued at the time of issue of such 
Options and the consideration received by the Corporation for the Additional 
Shares of Common Stock deemed to have been then issued was the consideration 
actually received by the Corporation for the issue of all such Options, 
whether or not exercised, plus the consideration deemed to have been received 
by the Corporation upon the issue of the Convertible Securities with respect 
to which such Options were actually exercised;

                                        (D)     no readjustment pursuant to 
clause (B) or (C) above shall have the effect of increasing the Series A-3 
Conversion Price to an amount which exceeds the lower of (i) the Series A-3 
Conversion Price on the original adjustment date, or (ii) the Series A-3 
Conversion Price that would have resulted from any issuance of Additional 
Shares of Common Stock between the original adjustment date and such 
readjustment date; and

                                        (E)     in the case of any Options 
which expire by their terms not more than thirty (30) days after the date of 
issue thereof, no adjustment of the Series A-3 Conversion Price shall be made 
until the expiration or exercise of all such Options.

                              (iv)     Adjustment of Series A-3 Conversion 
Price Upon Issuance of Additional Shares of Common Stock.  In the event the 
Corporation shall issue Additional Shares of Common Stock (including 
Additional Shares of Common Stock deemed to be issued pursuant to Section 
6(d)(2)(iii), but excluding stock dividends, subdivisions or split-ups that 
are the subject of adjustment pursuant to Section 6(d)(i)) without 
consideration or for a consideration per share less than the Series A-3 
Conversion Price, in effect on the date of, and immediately prior to such 
issue, then and in such event, such Series A-3 Conversion Price shall be 
reduced, concurrently with such issue, to a price (calculated to the nearest 
cent) determined by multiplying such Series A-3 Conversion Price by a 
fraction, the numerator of which shall be the sum of (i) the number of shares 
of Common Stock outstanding immediately prior to such issue, (ii) the number 
of shares of Common Stock issuable upon conversion of the Preferred Stock 
outstanding immediately prior to such issue and (iii) the number of shares of 
Common Stock which the aggregate consideration received by the Corporation 
for the total number of Additional Shares of Common Stock so issued would 
purchase at such Series A-3 Conversion Price; and the denominator of which 
shall be 
the sum of (i) the number of shares of Common Stock outstanding immediately 
prior 
to such issue, (ii) the number of shares of Common Stock issuable upon 
conversion of the Preferred Stock outstanding immediately prior to such issue 
and (iii)  the number of such Additional Shares of Common Stock so issued; 
and provided further that, for the purposes of this Section 6(d)(2)(iv), all 
shares of Common Stock issuable upon exercise of outstanding Options or 
conversion of outstanding Convertible Securities shall be deemed to be 
outstanding, and immediately after any Additional Shares of Common Stock are 
deemed issued pursuant to Section 6(d)(2)(iii), such Additional Shares of 
Common Stock shall be deemed to be outstanding.

                              (v)     Determination of Consideration.  For 
purposes of this Section 6(d)(2), the consideration received by the 
Corporation for the issue of any Additional Shares of Common Stock shall be 
computed as follows:

                                   (1)     Cash and Property:  Such 
consideration shall:

                                        (A)     insofar as it consists of 
cash, be computed at the aggregate amount of cash received by the Corporation 
(excluding amounts paid or payable for accrued interest or accrued dividends);

                                        (B)     insofar as it consists of 
property other than cash, be computed at the fair value thereof at the time 
of such issue, as determined in good faith by the Board of Directors; and

                                        (C)     in the event Additional 
Shares 
of Common Stock are issued together with other shares or securities or other 
assets of the Corporation for consideration which covers both, be the 
proportion of such consideration so received, computed as provided in clauses 
(A) and (B) above, as determined in good faith by the Board of Directors.

                              (2)     Options and Convertible Securities.  
The consideration per share received by the Corporation for Additional Shares 
of 
Common Stock deemed to have been issued pursuant to Section 6(d)(2)(iii)(1), 
relating to Options and Convertible Securities, shall be determined by 
dividing

                                   (x)     the total amount, if any, received 
or receivable by the Corporation as consideration for the issue of such 
Options or Convertible Securities, plus the minimum aggregate amount of 
additional consideration (as set forth in the instruments relating thereto, 
without regard to any provision contained therein for a subsequent adjustment 
of such consideration) payable to the Corporation upon the exercise of such 
Option or the conversion or exchange of such Convertible Securities, or in 
the case of Options for Convertible Securities, the exercise of such Options 
for 
Convertible Securities and the conversion or exchange of such Convertible 
Securities by

                                   (y)     the maximum number of shares of 
Common Stock (as set forth in the instruments relating thereto, without 
regard to any provision contained therein for a subsequent adjustment of such 
number) issuable upon the exercise of such Options or the conversion or 
exchange of 
such Convertible Securities.

               (g)     No Impairment.  Except as provided in Section 8, the 
Corporation will not, by amendment of its Amended and Restated Certificate of 
Incorporation or this Certificate of Designation or through any 
reorganization, transfer of assets, consolidation, merger, dissolution, issue 
or sale of securities or any other voluntary action, avoid or seek to avoid 
the observance or performance of any of the terms to be observed or performed 
hereunder by the Corporation but will at all times in good faith assist in 
the carrying out of all the provisions of this Section 6 and in the taking of 
all 
such action as may be necessary or appropriate in order to protect the 
Conversion Rights of the holders of the Series A-3 Preferred Stock against 
impairment.

               (h)     Certificate as to Adjustments.  Upon the occurrence of 
each adjustment or readjustment of the Series A-3 Conversion Price pursuant 
to this Section 6, the Corporation at its expense shall promptly compute such 
adjustment or readjustment in accordance with the terms hereof and furnish to 
each holder of Series A-3 Preferred a certificate setting forth such 
adjustment or readjustment and showing in detail the facts upon which such 
adjustment or readjustment is based.  The Corporation shall, upon the written 
request at any time of any holder of Series A-3 Preferred, furnish or cause 
to be furnished to such holder a like certificate setting forth (i) such 
adjustments and readjustments, (ii) the Series A-3 Conversion Price at the 
time in effect, and (iii) the number of shares of Common Stock and the 
amount, if any, of other property which at the time would be received upon 
the 
conversion of Series A-3 Preferred.

               (i)     Notices of Record Date.  In the event that the 
Corporation shall propose at any time:

                         (i)     to declare any dividend or distribution upon 
its Common Stock, whether in cash, property, stock or other securities, 
whether or not a regular cash dividend and whether or not out of earnings or 
earned surplus;

                         (ii)     to effect any reclassification or 
capitalization of its Common Stock outstanding involving a change in the 
Common Stock; or
                         (iii)     to merge or consolidate with or into any 
other person or entity, or sell, lease or convey all or substantially all its 
property or business, or to liquidate, dissolve or wind up;

then, in connection with each such event, the Corporation shall send to the 
holders of Series A-3 Preferred:

                              (1)     at least twenty (20) days' prior 
written notice of the date on which a record shall be taken for such 
dividend, 
distribution or subscription rights (and specifying the date on which the 
holders of Common Stock shall be entitled thereto) or for determining rights 
to vote in respect of the matters referred to in (ii) and (iii) above; and

                              (2)     in the case of the matters referred to 
in (ii) and (iii) above, at least twenty (20) days' prior written notice of 
the date when the same shall take place (and specifying the date on which the 
holders of Common Stock shall be entitled to exchange their Common Stock for 
securities or other property deliverable upon the occurrence of such event).

     Each such written notice shall be delivered personally or given by first 
class mail, postage prepaid, addressed to the holders of the Series A-3 
Preferred at the address for each such holder as shown on the books of the 
Corporation.  The above written notice requirement may be waived by the 
holders of a majority of the then outstanding Series A-3 Preferred Stock.

               (h)          Limits on Conversion.  Notwithstanding anything 
herein to the contrary, the Series A-2, Series A-3, and Series B-1 Preferred 
Stock of the Corporation and any additional shares of Preferred Stock issued 
by the Corporation prior to Stockholder Approval (as defined below), and the 
outstanding warrants to purchase Common Stock of the Corporation (issued or 
issuable to holders of such shares of Preferred Stock pursuant to agreements 
outstanding as of February 26, 1999 or entered into prior to Stockholder 
Approval) (collectively, the "Securities") shall not be convertible into or 
exercisable for (as the case may be) shares of Common Stock in excess of 
1,533,709 shares (as adjusted for Recapitalizations and the like) (the "19.9% 
Cap" or the "Allowed Conversion Shares"), unless the Corporation has received 
stockholder approval to eliminate such 19.9% Cap at a duly held meeting of 
the stockholders in calendar 1999 (the  "Stockholder Approval").  Until 
Stockholder Approval has been obtained (or, if Stockholder Approval  is not 
obtained, then continuing thereafter) the 19.9% Cap shall apply and each 
holder of Securities (each a "Holder") shall have the right to convert its 
Preferred Stock or exercise its warrants only up to its pro rata portion of 
the Allowed Conversion Shares.  A Holder may waive in writing its right to 
convert or exercise (or transfer to another Holder) its pro rata portion of 
the Allowed Conversion Shares.  In the event that a Holder converts or 
exercises its Securities, then the number of Allowed Conversion Shares will 
be reduced by such amount.

          SECTION 7.     Status of Converted Stock.  In case any shares of 
Series A-3 Preferred shall be repurchased or converted pursuant to Section 6, 
the shares so repurchased or converted shall be canceled and shall not be 
issued by the Corporation as Series A-3 Preferred and this Certificate of 
Designation shall be appropriately amended to effect the corresponding 
reduction in the Corporation's authorized Series A-3 Preferred.

          SECTION 8.     Covenants.  In addition to any other rights provided 
by law, so long as at least twenty-five percent (25%) of the authorized 
Series A-3 Preferred shall be outstanding, the Corporation shall not, without 
first 
obtaining the affirmative vote or written consent of the holders of not less 
than a majority of the outstanding shares of Series A-3 Preferred:

               (j)     amend or repeal any provision of the Corporation's 
Amended or Restated Certificate of Incorporation, certificates of designation 
or Bylaws if such action would materially and adversely alter or change the 
preferences, rights, privileges or powers of, or the restrictions provided 
for the benefit of, the Series A-3 Preferred; or 

               (k)     authorize or issue shares of any class or series of 
stock having any preference or priority as to dividends or assets superior to 
or on parity with any such preference or priority of the Series A-3 Preferred.

CERTIFICATE OF DESIGNATION OF RIGHTS, PREFERENCES AND
PRIVILEGES OF SERIES B-1 PREFERRED STOCK

OF

SUPERCONDUCTOR TECHNOLOGIES INC.


Pursuant to Section 151 of the General Corporation Law
of the State of Delaware

     I, Peter Thomas, the Chief Executive Officer of Superconductor 
Technologies Inc., a corporation organized and existing under the General 
Corporation Law of the State of Delaware (the "Corporation"), in accordance 
with the provisions of Section 103 thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by 
the Amended and Restated Certificate of Incorporation of the Corporation, the 
Board of Directors on February 4, 1999 adopted the following resolution 
creating a series of 50,000 shares of Preferred Stock designated as Series 
B-1 
Preferred Stock.

     RESOLVED: That pursuant to the authority vested in the Board of 
Directors of the Corporation by the Amended and Restated Certificate of 
Incorporation, the Board of Directors does hereby provide for the issue of a 
series of Preferred Stock, par value $0.001 per share, of the Corporation, to 
be 
designated Series B-1 Preferred Stock (the "Series B-1 Preferred Stock"), 
consisting of 50,000 shares, and to the extent that the designations, powers, 
preferences and relative and other special rights and the qualifications, 
limitations and restrictions of the Series B-1 Preferred Stock are not stated 
and expressed in the Amended and Restated Certificate of Incorporation, does 
hereby fix and herein state and express such designations, powers, 
preferences and relative and other special rights and the qualifications, 
limitations 
and restrictions thereof, as follows (all terms used herein which are defined 
in 
the Amended and Restated Certificate of Incorporation shall be deemed to have 
the meanings provided therein):

          SECTION 1.     Designation and Amount.  The shares of such Series 
B-1 Preferred Stock shall be designated as "Series B-1 Preferred Stock", par 
value $0.001 per share, and the number of shares constituting such series 
shall be 50,000. 

          SECTION 2.     Rank.  Except as provided in Section 8, the Series 
B-1 Preferred Stock shall rank (i) prior to the Corporation's common stock, 
par value $.001 per share (the "Common Stock"); (ii) pari passu with the 
Series A-2 Preferred Stock, the Series A-3 Preferred Stock, and with any 
class or series of capital stock of the Corporation hereafter created 
specifically 
ranking, by its terms, on parity with the Series B-1 Preferred Stock; and 
(iii) junior to any class or series of capital stock of the Corporation 
hereafter created specifically ranking, by its terms, senior to the Series 
B-1 Preferred Stock, in each case as to distribution of assets upon 
liquidation, 
dissolution or winding up of the Corporation, whether voluntary or 
involuntary.

          SECTION 3.     Dividends.  The holders of shares of Series B-1 
Preferred Stock shall be entitled to receive dividends, out of funds legally 
available therefor, payable in preference and priority to any payment of any 
dividend on Common Stock of the Corporation, at the rate of $5.60 per share 
(adjusted for any recapitalization, stock combinations, stock dividends, 
stock splits and the like ("Recapitalizations")) per annum for the Series B-1 
Preferred Stock; provided, however, that in the event Stockholder Approval 
(as defined in Section 6(h) below) is not obtained, then effective as of 
September 2, 1998, the $5.60 dividend amount shall be increased to $16.00 per
share (adjusted for Recapitalizations).  Such dividends shall be cumulative, 
accrue 
daily (effective September 2, 1998), and be paid quarterly in cash or as an 
addition to the Series B-1 Liquidation Preference (as defined below). No 
dividend shall be paid on the Common Stock in any year, other than dividends 
payable solely in Common Stock, until all dividends due and payable on the 
Preferred Stock have been declared and paid, and then such dividends on the 
Common Stock shall not be in excess of the dividends paid on the Preferred 
Stock unless the amount of such excess is also paid on the Preferred Stock on 
an as-converted per share basis.

          SECTION 4.     Liquidation Preference.  In the event of any 
liquidation, dissolution or winding up of the Corporation, either voluntary 
or involuntary (a "Liquidation Event"), distributions to the stockholders of 
the 
Corporation shall be made in the following manner:

               (a)     The holders of Series B-1 Preferred Stock shall be 
entitled to receive, on a pari passu basis with the holders of Series A-2, 
Series A-3 and Series C Preferred Stock and any other series of Preferred 
Stock ranked pari passu with the Series B-1 Preferred Stock but prior and in 
preference to any distribution of any of the assets or surplus funds of the 
Corporation to the holders of any series of Preferred Stock junior to Series 
B-1 Preferred Stock or holders of the Common Stock by reason of their 
ownership of such stock, an amount per share equal to the sum (the "Series 
B-1 Liquidation Preference") of (i) $80.00 for each share of Series B-1 
Preferred 
Stock (the "Original Purchase Price") then held by them, adjusted for any 
Recapitalizations with respect to such shares and (ii) an amount equal to all 
unpaid dividends on the Series B-1 Preferred Stock held by them.  If the 
assets and funds thus distributed among the holders of the Preferred Stock 
shall be insufficient to permit the payment to such holders of their full 
preferential amount, then the entire assets and funds of the Corporation 
legally available for distribution shall be distributed ratably among the 
holders of the Preferred Stock in proportion to the aggregate preferential 
amount of shares of Preferred Stock outstanding as of the date of the 
distribution upon the occurrence of such event.  After payment has been made 
to the holders of the Preferred Stock of the full preferential amounts to 
which they shall be entitled, the holders of the Common Stock shall be 
entitled to share ratably in the remaining assets, based on the number of 
shares of Common Stock held.

               (b)     For purposes of this Section 4, a merger or 
consolidation of the Corporation with or into any other corporation or 
corporations, or the merger of any other corporation or corporations into the 
Corporation, or the sale of all or substantially all of the assets of the 
Corporation, or any other corporate reorganization, in which consolidation, 
merger, sale of assets or reorganization the stockholders of the Corporation 
receive distributions in cash or securities of another corporation or 
corporations as a result of such consolidation, merger, sale of assets or 
reorganization, shall be treated as a Liquidation Event unless the 
stockholders of this Corporation immediately prior to such consolidation, 
merger, sale of assets or reorganization hold or control more than fifty 
percent (50%) of the voting equity securities of the successor or surviving 
corporation immediately following such consolidation, merger, sale of assets 
or reorganization, in which case such consolidation, merger, sale of assets 
or reorganization shall not be treated as a Liquidation Event.

          SECTION 5.     Voting Rights.  Except as otherwise required by law, 
the Amended and Restated Certificate of Incorporation or Bylaws of the 
Corporation or this Certificate of Designation, the holder of each share of 
Common Stock issued and outstanding shall have one vote and the holder of 
each share of Series B-1 Preferred Stock shall be entitled to the number of 
votes 
equal to the number of shares of Common Stock into which such share of Series 
B-1 Preferred Stock could be converted, subject to the limits set forth in 
Section 6(h) below, at the record date for determination of the stockholders 
entitled to vote on such matters, or, if no such record date is established, 
at the date such vote is taken or any written consent of stockholders is 
solicited, such votes to be counted together with all other shares of stock 
of the Corporation having general voting power and not separately as a class. 
Holders of Common Stock and Series B-1 Preferred Stock shall be entitled to 
notice of any stockholders' meeting in accordance with the Bylaws of the 
Corporation.  Fractional votes by the holders of Series B-1 Preferred Stock 
shall not, however, be permitted and any fractional voting rights shall 
(after aggregating all shares into which shares of Series B-1 Preferred Stock 
held 
by each holder could be converted) be rounded to the nearest whole number.
          
          SECTION 6.     Conversion.  The holders of Series B-1 Preferred 
Stock have conversion rights as follows (the "Conversion Rights"):

               (a)     Right to Convert.  Subject to the limits set forth in 
Section 6(h) below, each share of Series B-1 Preferred Stock shall be 
convertible, at the option of the holder thereof, at any time after the date 
of issuance of such share at the office of the Corporation or any transfer 
agent for the Series B-1 Preferred Stock, into such number of fully paid and 
nonassessable shares of Common Stock as is determined by dividing $80.00 by 
the initial Series B-1 Conversion Price.  The term "Series B-1 Conversion 
Price" as used herein shall mean initially $4.00 and shall be subject to 
adjustment as provided below.
               
               (b)     Automatic Conversion. Subject to the limits set forth 
in Section 6(h) below, each share of Series B-1 Preferred Stock shall 
automatically be converted into shares of Common Stock at the then effective 
Series B-1 Conversion Price for such series upon the election of holders of 
at least a majority of the then outstanding shares of Series B-1 Preferred 
Stock.

               (c)     Mechanics of Conversion.  The mechanics of conversion 
set forth in this Section 6(c) are subject to the limits set forth in Section 
6(h) below.  No fractional shares of Common Stock shall be issued upon 
conversion of Series B-1 Preferred Stock.  In lieu of any fractional shares 
to which the holder would otherwise be entitled, the Corporation shall pay 
cash 
equal to such fraction multiplied by the then effective Series B-1 Conversion 
Price.  Before any holder of Series B-1 Preferred Stock shall be entitled to 
convert the same into full shares of Common Stock and to receive certificates 
therefor, the holder shall surrender the certificate or certificates 
therefor, duly endorsed, at the office of the Corporation or of any transfer 
agent for 
the Series B-1 Preferred Stock, and shall give written notice (in the form of 
Exhibit A attached hereto) to the Corporation (the "Notice of Conversion") at 
such office that the holder elects to convert the same and specifying the 
date of conversion (the "Conversion Date"); provided, however, that in the 
event 
of an automatic conversion pursuant to Section 6(b), the outstanding shares 
of 
Series B-1 Preferred Stock shall be converted automatically without any 
further action by the holders of such shares and whether or not the 
certificates representing such shares are surrendered to the Corporation or 
its transfer agent and provided further, that the Corporation shall not be 
obligated to issue certificates evidencing the shares of Common Stock 
issuable upon such automatic conversion unless the certificates evidencing 
such shares 
of Series B-1 Preferred Stock are either delivered to the Corporation or its 
transfer agent as provided above, or the holder notifies the Corporation or 
its transfer agent that such certificates have been lost, stolen or destroyed 
and executes an agreement satisfactory to the Corporation to indemnify the 
Corporation from any loss incurred by it in connection with such 
certificates.  The Corporation shall, as soon as practicable after such 
delivery, or such agreement and indemnification in the case of a lost 
certificate, issue and deliver at such office to such holder of Series B-1 
Preferred Stock, a certificate or certificates for the number of shares of 
Common Stock to which such holder shall be entitled as aforesaid and a check 
payable to the holder in the amount of any cash amounts payable as the result 
of a conversion into fractional shares of Common Stock.  Such conversion 
shall be deemed to have been made immediately prior to the close of business 
on the 
date of such surrender of the shares of Series B-1 Preferred Stock to be 
converted, or in the case of automatic conversion then on the date of 
election by a majority of the then outstanding shares of Series B-1 Preferred 
Stock, 
and the person or persons entitled to receive the shares of Common Stock 
issuable upon such conversion shall be treated for all purposes as the record 
holder or holders of such shares of Common Stock on such date.
               
               (d)     (1)     Adjustment of Conversion Price of Series B-1 
Preferred Stock.  The Series B-1 Conversion Price shall be subject to 
adjustment from time to time as follows:

                              (i)     Adjustments for Subdivisions, 
Combinations or Consolidation of Common Stock.  In the event the outstanding 
shares of Common Stock shall be subdivided by stock split, stock dividends or 
otherwise, into a greater number of shares of Common Stock, the Series B-1 
Conversion Price then in effect shall, concurrently with the effectiveness of 
such subdivision, be proportionately decreased.  In the event the outstanding 
shares of Common Stock shall be combined or consolidated, by reclassification 
or otherwise, into a lesser number of shares of Common Stock, the Series B-1 
Conversion Price then in effect shall, concurrently with the effectiveness of 
such combination or consolidation, be proportionately increased.

                              (ii)     Adjustments for Stock Dividends and 
Other Distributions.  In the event the Corporation at any time or from time 
to time makes, or fixes a record date for the determination of holders of 
Common 
Stock entitled to receive any distribution (excluding any repurchases of 
securities by the Corporation not made on a pro rata basis from all holders 
of any class of the Corporation's securities) payable in property or in 
securities of the Corporation other than shares of Common Stock, and other 
than as otherwise adjusted in this Section 6 or as provided in Section 3, 
then and in each such event the holders of Series B-1 Preferred Stock shall 
receive at the time of such distribution, the amount of property or the number 
of 
securities of the Corporation that they would have received had their Series 
B-1 Preferred Stock been converted into Common Stock on the date of such 
event.

                              (iii)     Adjustments for Reclassification, 
Exchange and Substitution.  Except as provided in Section 4 upon any 
liquidation, dissolution or winding up of the Corporation, if the Common 
Stock issuable upon conversion of the Series B-1 Preferred Stock shall be 
changed 
into the same or a different number of shares of any other class or classes 
of stock, whether by capital reorganization, reclassification or otherwise 
(other than a subdivision or combination of shares provided for above), each 
share 
of Series B-1 Preferred Stock shall thereafter be convertible into the number 
of 
shares of stock or other securities or property to which a holder of the 
number of shares of Common Stock of the Corporation deliverable upon 
conversion of such share of Series B-1 Preferred Stock shall have been 
entitled upon such reorganization or reclassification.

                    (2)     Adjustments of Series B-1 Conversion Price for 
Diluting Issues.  In addition to the adjustment of the Series B-1 Conversion 
Price provided in Section 6(d)(1) above, the Series B-1 Conversion Price 
shall be subject to further adjustment from time to time as follows:

                    (i)     Special Definitions.  For purposes of this 
Section 6(e)(2), the following definitions shall apply:

                         (1)     "Options" shall mean rights, options or 
warrants to subscribe for, purchase or otherwise acquire either Common Stock 
or Convertible Securities.

                         (2)     "Original Issue Date" shall mean September 2, 
1998.

                         (3)     "Convertible Securities" shall mean 
securities convertible into or exchangeable for Common Stock.

                         (4)     "Additional Shares of Common Stock" shall 
mean all shares of Common Stock issued (or, pursuant to Section 6(d)(2)(iii), 
deemed to be issued) by the Corporation after the Original Issue Date other 
than shares of Common Stock issued or issuable:

                              (A)     upon conversion of shares of the 
Preferred Stock;

                              (B)     to officers, directors and employees 
of, 
and consultants to, the Corporation pursuant to plans and arrangements 
approved by the Board of Directors;

                              (C)     as a dividend or other distribution on 
the Preferred Stock or pursuant to clause (i), (ii) or (iii) of Section 
6(d)(1);

                              (D)     upon the exercise of options issued 
prior to the Original Issue Date; 

                              (E)     to research or development 
collaborators 
or to banks or other institutional lendors or lessors in connection with 
capital asset leases or borrowings for the acquisition of capital assets, 
pursuant to any arrangement approved by the Board of Directors; or

                           (F)            upon exercise of warrants 
outstanding on the Original Issue Date or warrants to be issued pursuant to 
agreements outstanding on the Original Issue Date (including without 
limitation the following warrants:  warrant, dated as of November 22, 1997, 
the warrants issued or issuable pursuant to the Exchange Agreement dated as 
of 
February __, 1999, the Securities Purchase Agreement dated as of September 2, 
1998 and the Series C Preferred Stock Purchase Agreement, the warrant, dated 
as of December 21, 1998 and any securities issued or issuable pursuant to the 
Letter Agreement between the Company and Tanner Unman Securities, Inc., dated 
as August 10, 1998;
                              
                              (G)     with the written approval of the 
holders 
of a majority of the outstanding Series B-1 Preferred;
                              
                              (H)     by way of dividend or other 
distributions on securities referred to in clauses (A), (B), (C), (D), (E), 
(F) and (G) above.

                    (ii)     No Adjustment of Series B-1 Conversion Price.  
No 
adjustment in the Series B-1 Conversion Price of a particular share of Series 
B-1 Preferred Stock shall be made in respect of the issuance of Additional 
Shares of Common Stock unless the consideration per share for an Additional 
Share of Common Stock issued or deemed to be issued by the Corporation is 
less 
than the Series B-1 Conversion Price in effect on the date of, and 
immediately 
prior to such issue, for such share of Series B-1 Preferred Stock.

                         (iii)     Deemed Issue of Additional Shares of 
Common Stock.

                                   (1)     Options and Convertible 
Securities.  Except as otherwise provided in Section 6(d)(2)(i) above, in the 
event the Corporation at any time or from time to time after the Original 
Issue Date shall issue any Options or Convertible Securities or shall fix a 
record date for the determination of any holders of any class of securities 
entitled to receive any such Options or Convertible Securities, then the 
maximum number of shares (as set forth in the instrument relating thereto 
without regard to any provisions contained therein for a subsequent 
adjustment 
of such number) of Common Stock issuable upon the exercise of such Options 
or, 
in the case of Convertible Securities and Options therefor, the conversion or 
exchange of such Convertible Securities, shall be deemed to be Additional 
Shares of Common Stock issued as of the time of such issue or, in case such a 
record date shall have been fixed, as of the close of business on such record 
date, provided that Additional Shares of Common Stock shall not be deemed to 
have been issued unless the consideration per share (determined pursuant to 
Section 6(d)(2)(v) below) of such Additional Shares of Common Stock would be 
less than the Series B-1 Conversion Price in effect on the date of and 
immediately prior to such issue, or such record date, as the case may be, and 
provided further that in any such case in which additional shares of Common 
Stock are deemed to be issued:

                                        (A)     no further adjustment in the 
Series B-1 Conversion Price shall be made upon the subsequent issue of 
Convertible Securities or shares of Common Stock upon the exercise of such 
Options or conversion or exchange of such Convertible Securities;

                                        (B)     if such Options or 
Convertible 
Securities by their terms provide, with the passage of time or otherwise, for 
any increase or decrease in the consideration payable to the Corporation, or 
increase or decrease in the number of shares of Common Stock issuable, upon 
the exercise, conversion or exchange thereof, the Series B-1 Conversion Price 
computed upon the original issue thereof (or upon the occurrence of a record 
date with respect thereto), and any subsequent adjustments based thereon, 
shall, upon any such increase or decrease becoming effective, be recomputed 
to 
reflect such increase or decrease insofar as it affects such Options or the 
rights of conversion or exchange under such Convertible Securities;

                                        (C)     upon the expiration of any 
such Options or any rights of conversion or exchange under such Convertible 
Securities which shall not have been exercised, the Series B-1 Conversion 
Price computed upon the original issue thereof (or upon the occurrence of a 
record date with respect thereto), and any subsequent adjustments based 
thereon, shall, upon such expiration, be recomputed as if:

                                             (I)     in the case of 
Convertible Securities or Options for Common Stock, the only additional 
shares 
of Common Stock issued were shares of Common Stock, if any, actually issued 
upon the exercise of such Options or the conversion or exchange of such 
Convertible Securities, and the consideration received therefor was the 
consideration actually received by the Corporation for the issue of all such 
Options, whether or not exercised, plus the consideration actually received 
by 
the Corporation upon such exercise, or for the issue of all such Convertible 
Securities which were actually converted or exchanged, plus the additional 
consideration, if any, actually received by the Corporation upon such 
conversion or exchange, and

                                             (II)     in the case of Options 
for Convertible Securities, only the Convertible Securities, if any, actually 
issued upon the exercise thereof were issued at the time of issue of such 
Options and the consideration received by the Corporation for the Additional 
Shares of Common Stock deemed to have been then issued was the consideration 
actually received by the Corporation for the issue of all such Options, 
whether or not exercised, plus the consideration deemed to have been received 
by the Corporation upon the issue of the Convertible Securities with respect 
to which such Options were actually exercised;
                                        (D)     no readjustment pursuant to 
clause (B) or (C) above shall have the effect of increasing the Series B-1 
Conversion Price to an amount which exceeds the lower of (i) the Series B-1 
Conversion Price on the original adjustment date, or (ii) the Series B-1 
Conversion Price that would have resulted from any issuance of Additional 
Shares of Common Stock between the original adjustment date and such 
readjustment date; and

                                        (E)     in the case of any Options 
which expire by their terms not more than thirty (30) days after the date of 
issue thereof, no adjustment of the Series B-1 Conversion Price shall be made 
until the expiration or exercise of all such Options.

                              (iv)     Adjustment of Series B-1 Conversion 
Price Upon Issuance of Additional Shares of Common Stock.  In the event the 
Corporation shall issue Additional Shares of Common Stock (including 
Additional Shares of Common Stock deemed to be issued pursuant to Section 
6(d)(2)(iii), but excluding stock dividends, subdivisions or split-ups that 
are the subject of adjustment pursuant to Section 6(d)(i)) without 
consideration or for a consideration per share less than the Series B-1 
Conversion Price, in effect on the date of, and immediately prior to such 
issue, then and in such event, such Series B-1 Conversion Price shall be 
reduced, concurrently with such issue, to a price (calculated to the nearest 
cent) determined by multiplying such Series B-1 Conversion Price by a 
fraction, the numerator of which shall be the sum of (i) the number of shares 
of Common Stock outstanding immediately prior to such issue, (ii) the number 
of shares of Common Stock issuable upon conversion of the Preferred Stock 
outstanding immediately prior to such issue and (iii) the number of shares of 
Common Stock which the aggregate consideration received by the Corporation 
for 
the total number of Additional Shares of Common Stock so issued would 
purchase 
at such Series B-1 Conversion Price; and the denominator of which shall be 
the 
sum of (i) the number of shares of Common Stock outstanding immediately prior 
to such issue, (ii) the number of shares of Common Stock issuable upon 
conversion of the Preferred Stock outstanding immediately prior to such issue 
and (iii)  the number of such Additional Shares of Common Stock so issued; 
and 
provided further that, for the purposes of this Section 6(d)(2)(iv), all 
shares of Common Stock issuable upon exercise of outstanding Options or 
conversion of outstanding Convertible Securities shall be deemed to be 
outstanding, and immediately after any Additional Shares of Common Stock are 
deemed issued pursuant to Section 6(d)(2)(iii), such Additional Shares of 
Common Stock shall be deemed to be outstanding.

                              (v)     Determination of Consideration.  For 
purposes of this Section 6(d)(2), the consideration received by the 
Corporation for the issue of any Additional Shares of Common Stock shall be 
computed as follows:

                                   (1)     Cash and Property:  Such 
consideration shall:

                                        (A)     insofar as it consists of 
cash, be computed at the aggregate amount of cash received by the Corporation 
(excluding amounts paid or payable for accrued interest or accrued dividends);

                                        (B)     insofar as it consists of 
property other than cash, be computed at the fair value thereof at the time 
of 
such issue, as determined in good faith by the Board of Directors; and
                                        (C)     in the event Additional 
Shares 
of Common Stock are issued together with other shares or securities or other 
assets of the Corporation for consideration which covers both, be the 
proportion of such consideration so received, computed as provided in clauses 
(A) and (B) above, as determined in good faith by the Board of Directors.

                              (2)     Options and Convertible Securities.  
The consideration per share received by the Corporation for Additional Shares 
of 
Common Stock deemed to have been issued pursuant to Section 6(d)(2)(iii)(1), 
relating to Options and Convertible Securities, shall be determined by 
dividing

                                   (x)     the total amount, if any, received 
or receivable by the Corporation as consideration for the issue of such 
Options or Convertible Securities, plus the minimum aggregate amount of 
additional consideration (as set forth in the instruments relating thereto, 
without regard to any provision contained therein for a subsequent adjustment 
of such consideration) payable to the Corporation upon the exercise of such 
Option or the conversion or exchange of such Convertible Securities, or in 
the 
case of Options for Convertible Securities, the exercise of such Options for 
Convertible Securities and the conversion or exchange of such Convertible 
Securities by

                                   (y)     the maximum number of shares of 
Common Stock (as set forth in the instruments relating thereto, without 
regard 
to any provision contained therein for a subsequent adjustment of such 
number) 
issuable upon the exercise of such Options or the conversion or exchange of 
such Convertible Securities.

               (e)     No Impairment.  Except as provided in Section 8, the 
Corporation will not, by amendment of its Amended and Restated Certificate of 
Incorporation or this Certificate of Designation or through any 
reorganization, transfer of assets, consolidation, merger, dissolution, issue 
or sale of securities or any other voluntary action, avoid or seek to avoid 
the observance or performance of any of the terms to be observed or performed 
hereunder by the Corporation but will at all times in good faith assist in 
the 
carrying out of all the provisions of this Section 6 and in the taking of all 
such action as may be necessary or appropriate in order to protect the 
Conversion Rights of the holders of the Series B-1 Preferred Stock against 
impairment.

               (f)     Certificate as to Adjustments.  Upon the occurrence of 
each adjustment or readjustment of the Series B-1 Conversion Price pursuant 
to 
this Section 6, the Corporation at its expense shall promptly compute such 
adjustment or readjustment in accordance with the terms hereof and furnish to 
each holder of Series B-1 Preferred Stock a certificate setting forth such 
adjustment or readjustment and showing in detail the facts upon which such 
adjustment or readjustment is based.  The Corporation shall, upon the written 
request at any time of any holder of Series B-1 Preferred Stock, furnish or 
cause to be furnished to such holder a like certificate setting forth (i) 
such 
adjustments and readjustments, (ii) the Series B-1 Conversion Price at the 
time in effect, and (iii) the number of shares of Common Stock and the 
amount, 
if any, of other property which at the time would be received upon the 
conversion of Series B-1 Preferred Stock.

               (g)     Notices of Record Date.  In the event that the 
Corporation shall propose at any time:

                         (i)     to declare any dividend or distribution upon 
its Common Stock, whether in cash, property, stock or other securities, 
whether or not a regular cash dividend and whether or not out of earnings or 
earned surplus;

                         (ii)     to effect any reclassification or 
capitalization of its Common Stock outstanding involving a change in the 
Common Stock; or

                         (iii)     to merge or consolidate with or into any 
other person or entity, or sell, lease or convey all or substantially all its 
property or business, or to liquidate, dissolve or wind up;
then, in connection with each such event, the Corporation shall send to the 
holders of Series B-1 Preferred Stock:

                              (1)     at least twenty (20) days' prior 
written 
notice of the date on which a record shall be taken for such dividend, 
distribution or subscription rights (and specifying the date on which the 
holders of Common Stock shall be entitled thereto) or for determining rights 
to vote in respect of the matters referred to in (ii) and (iii) above; and

                              (2)     in the case of the matters referred to 
in (ii) and (iii) above, at least twenty (20) days' prior written notice of 
the date when the same shall take place (and specifying the date on which the 
holders of Common Stock shall be entitled to exchange their Common Stock for 
securities or other property deliverable upon the occurrence of such event).

     Each such written notice shall be delivered personally or given by first 
class mail, postage prepaid, addressed to the holders of the Series B-1 
Preferred Stock at the address for each such holder as shown on the books of 
the Corporation.
     
                    (h)     Limits on Conversion.  Notwithstanding anything 
herein to the contrary, the Series A-2, Series A-3, Series B-1 and Series C 
Preferred Stock of the Company and the outstanding warrants to purchase 
Common 
Stock of the Company (issued or issuable to holders of such shares of 
Preferred Stock pursuant to agreements outstanding as of February __, 1999) 
(collectively, the "Securities") shall not be convertible into or exercisable 
for (as the case may be) shares of Common Stock in excess of 1,533,709 shares 
(the "19.9% Cap" or the "Allowed Conversion Shares"), unless the Company has 
received stockholder approval to eliminate such 19.9% Cap at a duly held 
meeting of the stockholders in calendar 1999 (the "Stockholder Approval").  
Until Stockholder Approval has been obtained (or, if Stockholder Approval is 
not obtained, then continuing thereafter) the 19.9% Cap shall apply and each 
holder of Securities (each a "Holder") shall have the right to convert or 
exercise its Securities only up to its pro rata portion of the Allowed 
Conversion Shares.  A Holder may waive in writing its right to convert or 
exercise its pro rata portion of the Allowed Conversion Shares.  In the event 
that a Holder converts or exercises its Securities, then the number of 
Allowed 
Conversion Shares will be reduced by such amount.

          SECTION 7.     Status of Converted Stock.  In case any shares of 
Series B-1 Preferred Stock shall be repurchased or converted pursuant to 
Section 6, the shares so repurchased or converted shall be cancelled and 
shall 
not be issued by the Corporation as Series B-1 Preferred and this Certificate 
of Designation shall be appropriately amended to effect the corresponding 
reduction in the Corporation's authorized Series B-1 Preferred Stock.
          
          SECTION 8.     Covenants.  In addition to any other rights provided 
by law, so long as at least twenty-five percent (25%) of the authorized 
Series 
B-1 Preferred Stock shall be outstanding, the Corporation shall not, without 
first obtaining the affirmative vote or written consent of the holders of not 
less than a majority of the outstanding shares of Series B-1 Preferred Stock:
               (a)     amend or repeal any provision of the Corporation's 
Amended or Restated Certificate of Incorporation, certificates of designation 
or Bylaws if such action would materially and adversely alter or change the 
preferences, rights, privileges or powers of, or the restrictions provided 
for 
the benefit of, the Series B-1 Preferred Stock; or 

               (b)     authorize or issue shares of any class or series of 
stock having any preference or priority as to dividends or assets superior to 
or on parity with any such preference or priority of the Series B-1 Preferred 
Stock.

Section 4       Representations and Warranties of the Purchaser 
The Purchaser hereby represents and warrants to the Company with respect to 
the purchase of Shares by and the issuance of the Warrants to such Purchaser, 
as follows:
4.1     Experience; Speculative Nature of Investment

 .  The Purchaser (or its principals or advisors) has substantial experience in 
evaluating and investing in private placement transactions of securities in 
companies similar to the Company so that it is capable of evaluating the 
merits and risks of its investment in the Company and has the capacity to 
protect its own interests.  The Purchaser acknowledges that its investment in 
the Company is highly speculative and entails a substantial degree of risk and 
the Purchaser is in a position to lose the entire amount of such investment.
4.2     Investment

 .  The Purchaser is acquiring the Warrants, Shares and the underlying Common 
Stock for investment for its own account, not as a nominee or agent, and not 
with the view to, or for resale in connection with, any distribution thereof.  
The Purchaser understands that the Warrants and Series C Preferred to be 
purchased hereby and the underlying Common Stock have not been, and will not 
be, registered under the Securities Act by reason of a specific exemption from 
the registration provisions of the Securities Act, the availability of which 
depends upon, among other things, the bona fide nature of the investment 
intent and the accuracy of the Purchaser's representations as expressed 
herein.  The Purchaser is an "accredited investor" within the meaning of 
Regulation D, Rule 501(a), promulgated by the Securities and Exchange 
Commission.
4.3     Rule 144

 .  The Purchaser acknowledges that the Warrants, Shares and the underlying 
Common Stock must be held indefinitely unless subsequently registered under 
the Securities Act or unless an exemption from such registration is 
available.  The Purchaser is aware of the provisions of Rule 144 promulgated 
under the Securities Act which permit limited resale of shares purchased in a 
private placement subject to the satisfaction of certain conditions, 
including, among other things, the existence of a public market for the 
shares, the availability of certain current public information about the 
Company, the resale occurring not less than one year after a party has 
purchased and paid for the security to be sold, the sale being effected 
through a "broker's transaction" or in transactions directly with a "market 
maker" and the number of shares being sold during any three-month period not 
exceeding specified limitations.  The Purchaser understands that the 
certificates evidencing the Warrants and Shares will be imprinted with a 
legend that prohibits the transfer of such securities unless they are 
registered or such registration is not required.
4.4     No Public Market

 .  The Purchaser understands that no public market now exists for the Warrants 
and the Series C Preferred to be issued by the Company and that the Company 
has made no assurances that a public market will ever exist for the Warrants 
and the Series C Preferred.
4.5     Access to Data

 .  The Purchaser has had an opportunity to discuss the Company's business, 
management and financial affairs with its management. The Purchaser has also 
had an opportunity to ask questions of officers of the Company, which 
questions were answered to its satisfaction. The Purchaser understands that 
such discussions, as well as any written information issued by the Company, 
were intended to describe certain aspects of the Company's business and 
prospects but were not a thorough or exhaustive description.
4.6     Authorization

 .  The Agreements, when executed and delivered by the Purchaser, will 
constitute valid and legally binding obligations of the Purchaser, enforceable 
in accordance with their terms, except as the indemnification provisions of 
Section 1.10 of the Rights Agreement may be limited by principles of public 
policy, and subject to laws of general application relating to bankruptcy, 
insolvency and the relief of debtors and rules of law governing specific 
performance, injunctive relief or other equitable remedies.
4.7     Brokers or Finders

 .  The Purchaser has not engaged any brokers, finders or agents, and the 
Company has not, and will not, incur, directly or indirectly, as a result of 
any action taken by Purchaser, any liability for brokerage or finders' fees or 
agents' commissions or any similar charges in connection with the Agreements.  
In the event that the preceding sentence is in any way inaccurate, such 
Purchaser agrees to indemnify and hold harmless the Company and each other 
Purchaser from any liability for any commission or compensation in the nature 
of a finder's fee (and the costs and expenses of defending against such 
liability) for which the Company, any other Purchaser, or any of their 
officers, directors, employees or representatives, is responsible.
4.8     Tax Liability

 .  The Purchaser has reviewed with its own tax advisors the federal, state, 
local and foreign tax consequences of this investment and the transactions 
contemplated by the Agreements.  With respect to such matters, the Purchaser 
relies solely on such advisors and not on any statements or representations of 
the Company or any of its agents other than the representations and warranties 
set forth herein.  The Purchaser understands that it (and not the Company) 
shall be responsible for its own tax liability that may arise as a result of 
this investment or the transactions contemplated by the Agreements.

March 5, 1999


Second Amended and Restated Stockholders Agreement

SUPERCONDUCTOR TECHNOLOGIES INC.
SECOND AMENDED AND RESTATED
STOCKHOLDER RIGHTS AGREEMENT


     This Second Amended and Restated Stockholder Rights Agreement (the 
"Agreement") is made as of February 26, 1999 between Superconductor 
Technologies Inc., a Delaware corporation (the "Company"), the holders of the 
Company's Series A and A-1 Preferred Stock (the "Series A and A-1 Holders"), 
the holders of the Company's Series A-2 and A-3 Preferred Stock pursuant to 
the Exchange Agreement, dated as of February 26, 1999, (the "Exchange 
Agreement") and, upon the consummation of the Series C Preferred Stock 
financing, the holders of the Company's Series C Preferred Stock.  The holders 
of the Company's Series A-2 and A-3 Preferred Stock, together with the 
purchasers of the Company's Series C Preferred Stock after the Closing (as 
defined in the Series C Preferred Stock Purchase Agreement) are, collectively, 
the "New Holders."

RECITALS

     A.     The Company and the Series A and A-1 Holders entered into that 
certain Amended and Restated Stockholder Rights Agreement, dated as of August 
11, 1998 (the "Existing Agreement"), which established certain terms and 
conditions upon which the Company's Series A and A-1 Preferred Stock and 
certain warrants are held by such holders, as set forth more particularly in 
the Existing Agreement.

     B.     In connection with the Exchange Agreement, the Company and the 
Series A and A-1 Holders have agreed, upon the terms and subject to the 
conditions contained therein, to exchange their shares of the Company's Series 
A and A-1 Preferred Stock and related warrants held by the Holders for shares 
of the Company's Series A-2 and A-3 Convertible Preferred Stock and related 
warrants that are convertible into the Conversion Stock (as defined below), 
upon the terms and subject to the limitations and conditions set forth in the 
Certificates of Designations, Rights, Preferences, Privileges and Restrictions 
with respect to the Series A-2 and A-3 Preferred Stock (the "Certificates of 
Designation").

     C.     To induce the Series A and A-1 Holders to execute and deliver the 
Exchange Agreement, the Company has agreed to provide certain registration 
rights under the Securities Act of 1933, as amended, and the rules and 
regulations thereunder, or any similar successor statue (collectively, the 
"1933 Act"), and applicable state securities laws.

     D.     Because the Company anticipates consummating an equity financing 
in the future with a proposed new Series C Preferred Stock, the Company 
desires to provide a further inducement to the potential purchasers to 
purchase the Series C Preferred Stock by establishing certain terms and 
conditions upon which such Series C Preferred Stock and related warrants would 
be held by such purchasers.

     E.     The Company and the Series A and A-1 Holders desire to amend and 
restate the Existing Agreement in its entirety, as set forth herein, to make 
the New Holders party thereto. 

     NOW, THEREFORE, the parties amend and restate the Existing Agreement in 
its entirety to read as follows:

SECTION 1

Restrictions on Transferability of Securities;
Compliance with Securities Act; Registration Rights

Conversion Stock (as defined below) and the Warrants (as defined below) shall 
not be sold, assigned, transferred or pledged except upon the conditions 
specified in this Section 1, which conditions are intended to ensure 
compliance with the provisions of the Securities Act (as defined below).  The 
Holders will cause any proposed purchaser, assignee, transferee, or pledgee of 
any such securities held by the Holders to agree to take and hold such 
securities subject to the provisions and upon the conditions specified in this

any Common Stock acquired pursuant to the exercise of the right of first 
refusal in Section 2 of this Agreement (including any shares issued by virtue 
of such shares upon any stock split, stock dividend, recapitalization or 
similar event), and (iii) any Common Stock of the Company issued or issuable 
in respect of the Conversion Stock upon any stock split, stock dividend, 
recapitalization or similar event, or any Common Stock otherwise issued or

securities transaction, or (B) sold or are, in the opinion of counsel for the 
Company, available for sale in a single transaction exempt from the

that all transfer restrictions and restrictive legends with respect thereto 
are removed upon the consummation of such sale.

          The terms "register," "registered" and "registration" refer to a

compliance with the Securities Act, and the declaration or ordering of the 
effectiveness of such registration statement.

other securities issued in respect of the Preferred Stock or the Conversion 
Stock upon any stock split, stock dividend, recapitalization, merger, 
consolidation or similar event, shall (unless otherwise permitted by the 
provisions of Section 1.4 below) be stamped or otherwise imprinted with a 
legend substantially  in the following form (in addition to any legend 
required under applicable state securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT 
AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.  SUCH SHARES 
MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION UNLESS THE 
COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT STATING 
THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS 
DELIVERY REQUIREMENTS OF SAID ACT.

          Each New Holder and Holder consents to the Company making a notation 
on its records and giving instructions to any transfer agent of the Preferred 
Stock, the Warrants or the Conversion Stock in order to implement the 
restrictions on transfer established in this Section 1.

     1.4     Restrictions on Transfer; Notice of Proposed Transfers.  The 
holder of each certificate representing Restricted Securities by acceptance 
thereof agrees to comply in all respects with the provisions of this Section 
1.4.  Prior to any proposed sale, assignment, transfer or pledge of any 
Restricted Securities (other than (i) a transfer not involving a change in 
beneficial ownership, (ii) in transactions involving the distribution without 
consideration of Restricted Securities by the Holder to any of its partners, 
or retired partners, or to the estate of any of its partners or retired 
partners, (iii) any transfer by any Holder to (A) any individual or entity 
controlled by, controlling, or under common control with, such Holder or (B) 
any individual or entity with respect to which such Holder (or any person 
controlled by, controlling, or under common control with, such Holder) has the 
power to direct investment decisions, or (iv) in transactions in compliance 
with Rule 144), and unless there is in effect a registration statement under 
the Securities Act covering the proposed transfer, the holder thereof shall 
give written notice to the Company of such holder's intention to effect such 
transfer, sale, assignment or pledge.  Each such notice shall describe the 
manner and circumstances of the proposed transfer, sale, assignment or pledge 
in sufficient detail, and shall be accompanied, at such holder's expense by 
either (i) an unqualified written opinion of legal counsel who shall be, and 
whose legal opinion shall be, reasonably satisfactory to the Company addressed 
to the Company, to the effect that the proposed transfer of the Restricted 
Securities may be effected without registration under the Securities Act, or 
(ii) a "no action" letter from the Commission to the effect that the transfer 
of such securities without registration will not result in a recommendation by 
the staff of the Commission that action be taken with respect thereto, 
whereupon the holder of such Restricted Securities shall be entitled to 
transfer such Restricted Securities in accordance with the terms of the notice 
delivered by the holder to the Company.  Each certificate evidencing the 
Restricted Securities transferred as above provided shall bear, except if such 
transfer is made pursuant to Rule 144, the appropriate restrictive legend set 
forth in Section 1.3 above, except that such certificate shall not bear such 
restrictive legend if in the opinion of counsel for such holder and the 
Company such legend is not required in order to establish compliance with any 
provision of the Securities Act.

     1.5     Requested Registration.

          (a)     Request for Registration.  In case the Company shall receive 
from Initiating Holders a written request that the Company effect any 
registration, qualification or compliance with respect to (1) at least fifty 
percent (50%) of the issued and outstanding Registrable Securities or (2) not 
less than that number of shares of Registrable Securities which would result 
in an anticipated aggregate offering price, net of underwriting discounts and 
commissions, greater than five million dollars ($5,000,000), the Company will:

                    (i)     promptly give written notice of the proposed 
registration, qualification or compliance to all other Holders; and


                    (ii)     as soon as practicable, use its best efforts to 
effect such registration, qualification or compliance (including, without 
limitation, appropriate qualification under applicable blue sky or other state 
securities laws and appropriate compliance with applicable regulations issued 
under the Securities Act and any other governmental requirements or 
regulations) as may be so requested and as would permit or facilitate the sale 
and distribution of all or such portion of such Registrable Securities as are 
specified in such request, together with all or such portion of the 
Registrable Securities of any Holder or Holders joining in such request as are 
specified in a written request received by the Company within twenty (20) days 
after receipt of such written notice from the Company;

               Provided, however, that the Company shall not be obligated to 
take any action to effect any such registration, qualification or compliance 
pursuant to this Section 2.5:

                         (A)     In any particular jurisdiction in which the 
Company would be required to execute a general consent to service of process 
in effecting such registration, qualification or compliance unless the Company 
is already subject to service in such jurisdiction and except as may be 
required by the Securities Act;

                         (B)     Prior to September 26, 1999;

                         (C)     During the period starting with the date 
sixty (60) days prior to the Company's estimated date of filing of, and ending 
on the date six (6) months immediately following the effective date of, any 
registration statement pertaining to securities of the Company (other than a 
registration of securities in a Rule 145 transaction or with respect to an 
employee benefit plan), provided that the Company is actively employing in 
good faith all reasonable efforts to cause such registration statement to 
become effective;

                         (D)     After the Company has effected one (1) such 
registration pursuant to this subparagraph 1.5(a), and such registration has 
been declared or ordered effective;

                         (E)     If the Company shall furnish to such Holders 
a certificate signed by the Chief Executive Officer of the Company stating 
that in the good faith judgment of the Board of Directors it would be 
seriously detrimental to the Company or its stockholders for a registration 
statement to be filed in the near future, then the Company's obligation to use 
its best efforts to register, qualify or comply under this Section 1.5 shall 
be deferred for a period not to exceed one hundred eighty (180) days from the 
date of receipt of written request from the Initiating Holders; provided that 
the Company may not exercise this deferral right more than once per twelve 
(12) month period.

               Subject to the foregoing clauses (A) through (E), the Company 
shall file a registration statement covering the Registrable Securities so 
requested to be registered as soon as practicable, after receipt of the 
request or requests of the Initiating Holders.


          (b)     Underwriting.  In the event that a registration pursuant to 
Section 1.5 is for a registered public offering involving an underwriting, the 
Company shall so advise the Holders as part of the notice given pursuant to 
Section 1.5(a)(i).  In such event, the right of any Holder to registration 
pursuant to Section 1.5 shall be conditioned upon such Holder's participation 
in the underwriting arrangements required by this Section 1.5, and the 
inclusion of such Holder's Registrable Securities in the underwriting to the 
extent requested shall be limited to the extent provided herein.

               The Company shall (together with all Holders proposing to 
distribute their securities through such underwriting) enter into an 
underwriting agreement in customary form with the managing underwriter 
selected for such underwriting by a majority in interest of the Initiating 
Holders, but subject to the Company's reasonable approval.  Notwithstanding 
any other provision of this Section 1.5, if the managing underwriter advises 
the Initiating Holders in writing that marketing factors require a limitation 
of the number of shares to be underwritten, then the Company shall so advise 
all holders of Registrable Securities and the number of shares of Registrable 
Securities that may be included in the registration and underwriting shall be 
allocated among all Holders in proportion, as nearly as practicable, to the 
respective amounts of Registrable Securities held by such Holders at the time 
of filing the registration statement.  No Registrable Securities excluded from 
the underwriting by reason of the underwriter's marketing limitation shall be 
included in such registration.  To facilitate the allocation of shares in 
accordance with the above provisions, the Company or the underwriters may 
round the number of shares allocated to any Holder to the nearest 100 shares.

               If any Holder of Registrable Securities disapproves of the 
terms of the underwriting, such person may elect to withdraw therefrom by 
written notice to the Company, the managing underwriter and the Initiating 
Holders.  The Registrable Securities and/or other securities so withdrawn 
shall also be withdrawn from registration, and such Registrable Securities 
shall not be transferred in a public distribution prior to one hundred eighty 
(180) days after the effective date of such registration, or such other 
shorter period of time as the underwriters may require.

     1.6     Company Registration.

          (a)     Notice of Registration.  If at any time or from time to time 
the Company shall determine to register any of its securities, either for its 
own account or the account of a security holder or holders, other than (i) a 
registration relating solely to employee benefit plans, or (ii) a registration 
relating solely to a Commission Rule 145 transaction, the Company will:

                    (i)     promptly give to each Holder written notice 
thereof; and

                    (ii)     include in such registration (and any related 
qualification under blue sky laws or other compliance), and in any 
underwriting involved therein, all the Registrable Securities specified in a 
written request or requests, made within twenty (20) days after receipt of 
such written notice from the Company, by any Holder.


          (b)     Underwriting.  If the registration of which the Company 
gives notice is for a registered public offering involving an underwriting, 
the Company shall so advise the Holders as a part of the written notice given 
pursuant to Section 1.6(a)(i).  In such event the right of any Holder to 
registration pursuant to Section 1.6 shall be conditioned upon such Holder's 
participation in such underwriting and the inclusion of Registrable Securities 
in the underwriting to the extent provided herein.  All Holders proposing to 
distribute their securities through such underwriting shall (together with the 
Company and the other holders distributing their securities through such 
underwriting) enter into an underwriting agreement in customary form with the 
managing underwriter selected for such underwriting by the Company.  
Notwithstanding any other provision of this Section 1.6, if the managing 
underwriter determines that marketing factors require a limitation of the 
number of shares to be underwritten, the managing underwriter and the Company 
may reduce the Registrable Securities to be included in such registration to 
the extent the underwriters deem necessary.  The Company shall so advise all 
Holders and other holders distributing their securities through such 
underwriting and the number of shares of Registrable Securities that may be 
included in the registration and underwriting shall be allocated among all the 
Holders in proportion, as nearly as practicable, to the respective amounts of 
Registrable Securities held by such Holder at the time of filing the 
Registration Statement.  To facilitate the allocation of shares in accordance 
with the above provisions, the Company may round the number of shares 
allocated to any Holder or holder to the nearest 100 shares.  If any Holder or 
holder disapproves of the terms of any such underwriting, he may elect to 
withdraw therefrom by written notice to the Company and the managing 
underwriter.  Any securities excluded or withdrawn from such underwriting 
shall be withdrawn from such registration, and shall not be transferred in a 
public distribution prior to one hundred eighty (180) days after the effective 
date of the registration statement relating thereto, or such other shorter 
period of time as the underwriters may require.

          (c)     Right to Terminate Registration.  The Company shall have the 
right to terminate or withdraw any registration initiated by it under this 
Section 1.6 prior to the effectiveness of such registration whether or not any 
Holder has elected to include securities in such registration.

     1.7     Limitations on Subsequent Registration Rights.  From and after 
the Closing Date, the Company shall not enter into any agreement granting any 
holder or prospective holder of any securities of the Company registration 
rights with respect to such securities unless (i) such new registration 
rights, including standoff obligations, are on a pari passu basis with those 
rights of the Holders hereunder, or (ii) such new registration rights, 
including standoff obligations, are subordinate to the registration rights 
granted Holders hereunder.

     1.8     Expenses of Registration.  All Registration Expenses incurred in 
connection with (i) one (1) registration pursuant to Section 1.5, (ii) all 
registrations pursuant to Section 1.6, shall be borne by the Company.  Unless 
otherwise stated, all Selling Expenses relating to securities registered on 
behalf of the Holders and all other Registration Expenses shall be borne by 
the Holders of such securities pro rata on the basis of the number of shares 
so registered.
          
     1.9     Registration Procedures.  In the case of each registration, 
qualification or compliance effected by the Company pursuant to this Section 
1, the Company will keep each Holder advised in writing as to the initiation 
of each registration, qualification and compliance and as to the completion 
thereof.  At its expense the Company will:

          (a)     Prepare and file with the Commission a registration 
statement with respect to such securities and use its best efforts to cause 
such registration statement to become and remain effective for at least one 
hundred eighty (180) days or until the distribution described in the 
Registration Statement has been completed;

          (b)     Furnish to the Holders participating in such registration 
and to the underwriters of the securities being registered such reasonable 
number of copies of the registration statement, preliminary prospectus, final 
prospectus and such other documents as such underwriters may reasonably 
request in order to facilitate the public offering of such securities;

          (c)     Prepare and file with the Commission such amendments and 
supplements to such registration statement and the prospectus used in 
connection with such registration statements as may be necessary to comply 
with the provisions of the Securities Act with respect to the disposition of 
all securities covered by such registration statement;

          (d)     Use its best efforts to register and qualify the securities 
covered by such registration statement under such other securities or Blue Sky 
laws of such jurisdictions as shall be reasonably requested by the Holders, 
provided that the Company shall not be required in connection therewith or as 
a condition thereto to qualify to do business or to file a general consent to 
service of process in any such states or jurisdictions; and

          (e)     In the event of any underwritten public offering, enter into 
and perform its obligations under an underwriting agreement, in usual and 
customary form, with the managing underwriter of such offering.  Each Holder 
participating in such underwriting shall also enter into and perform its 
obligations under such an agreement.

     1.10     Indemnification.

          (a)     The Company will indemnify each Holder, each of its officers 
and directors and partners, and each person controlling such Holder within the 
meaning of Section 15 of the Securities Act, with respect to which 
registration, qualification or compliance has been effected pursuant to this 
Section 1, and each underwriter, if any, and each person who controls any 
underwriter within the meaning of Section 15 of the Securities Act, against 
all expenses, claims, losses, damages or liabilities (or actions in respect 
thereof), including any of the foregoing incurred in settlement of any 
litigation, commenced or threatened, arising out of or based on any untrue 
statement (or alleged untrue statement) of a material fact contained in any 
registration statement, prospectus, offering circular or other document, or 
any amendment or supplement thereto, incident to any such registration, 
qualification or compliance, or based on any omission (or alleged omission) to 
state therein a material fact required to be stated therein or necessary to 
make the statements therein, in light of the circumstances in which they were 
made, not misleading, or any violation by the Company of the Securities Act, 
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), state 
securities law or any rule or regulation promulgated under such laws 
applicable to the Company in connection with any such registration, 
qualification or compliance, and within a reasonable period the Company will 
reimburse each such Holder, each of its officers and directors, and each 
person controlling such Holder, each such underwriter and each person who 
controls any such underwriter, for any legal and any other expenses reasonably 
incurred in connection with investigating, preparing or defending any such 
claim, loss, damage, liability or action; provided that the Company will not 
be liable in any such case to the extent that any such claim, loss, damage, 
liability or expense arises out of or is based on any untrue statement or 
omission or alleged untrue statement or omission, made in reliance upon and in 
conformity with written information furnished to the Company by an instrument 
duly executed by such Holder, controlling person or underwriter and stated to 
be specifically for use therein.

          (b)     Each Holder will, if Registrable Securities held by such 
Holder are included in the securities as to which such registration, 
qualification or compliance is being effected, indemnify the Company, each of 
its directors and officers, each underwriter, if any, of the Company's 
securities covered by such a registration statement, each person who controls 
the Company or such underwriter within the meaning of Section 15 of the 
Securities Act, and each other such Holder, each of its officers and directors 
and each person controlling such Holder within the meaning of Section 15 of 
the Securities Act, against all claims, losses, damages and liabilities (or 
actions in respect thereof) arising out of or based on any untrue statement 
(or alleged untrue statement) of a material fact contained in any such 
registration statement, prospectus, offering circular or other document, or 
any omission (or alleged omission) to state therein a material fact required 
to be stated therein or necessary to make the statements therein not 
misleading, and within a reasonable period will reimburse the Company, such 
Holders, such directors, officers, persons, underwriters or control persons 
for any legal or any other expenses reasonably incurred in connection with 
investigating or defending any such claim, loss, damage, liability or action, 
in each case to the extent, but only to the extent, that such untrue statement 
(or alleged untrue statement) or omission (or alleged omission) is made in 
such registration statement, prospectus, offering circular or other document 
in reliance upon and in conformity with written information furnished to the 
Company by an instrument duly executed by such Holder and stated to be 
specifically for use therein.

          (c)     Each party entitled to indemnification under this Section 
1.10 (the "Indemnified Party") shall give notice to the party required to 
provide indemnification (the "Indemnifying Party") promptly after such 
Indemnified Party has actual knowledge of any claim as to which indemnity may 
be sought, and shall permit the Indemnifying Party to assume the defense of 
any such claim or any litigation resulting therefrom, provided that counsel 
for the Indemnifying Party, who shall conduct the defense of such claim or 
litigation, shall be approved by the Indemnified Party (whose approval shall 
not unreasonably be withheld), and the Indemnified Party may participate in 
such defense at such party's expense, and provided further that the failure of 
any Indemnified Party to give notice as provided herein shall not relieve the 
Indemnifying Party of its obligations under this Section 1.10 unless the 
failure to give such notice is materially prejudicial to an Indemnifying 
Party's ability to defend such action and provided further, that the 
Indemnifying Party shall not assume the defense for matters as to which there 
is a conflict of interest or separate and different defenses.  No Indemnifying 
Party, in the defense of any such claim or litigation, shall, except with the 
consent of each Indemnified Party, consent to entry of any judgment or enter 
into any settlement which does not include as an unconditional term thereof 
the giving by the claimant or plaintiff to such Indemnified Party of a release 
from all liability in respect to such claim or litigation.  No Indemnifying 
Party shall be liable for indemnification hereunder with respect to any 
settlement or consent to judgment, in connection with any claim or litigation 
to which these indemnification provisions apply, that has been entered into 
without the prior consent of the Indemnifying Party (which consent will not be 
unreasonably withheld).

     1.11     Information by Holder.  The Holder or Holders of Registrable 
Securities included in any registration shall furnish to the Company such 
information regarding such Holder or Holders, the Registrable Securities held 
by them and the distribution proposed by such Holder or Holders as the Company 
may request in writing and as shall be required in connection with any 
registration, qualification or compliance referred to in this Section 1.11.

     1.12     Rule 144 Reporting.  With a view to making available the 
benefits of certain rules and regulations of the Commission which may at any 
time permit the sale of the Restricted Securities to the public without 
registration, the Company agrees to use its best efforts to:

          (a)     Make and keep public information available, as those terms 
are understood and defined in Rule 144 under the Securities Act, at all times 
after the effective date that the Company becomes subject to the reporting 
requirements of the Securities Act or the Exchange Act;

          (b)     Use its best efforts to file with the Commission in a timely 
manner all reports and other documents required of the Company under the 
Securities Act and the Exchange Act; and

          (c)     So long as a Holder owns any Restricted Securities to 
furnish to the Holder forthwith upon request a written statement by the 
Company as to its compliance with the reporting requirements of said Rule 144, 
and of the Securities Act and the Exchange Act, a copy of the most recent 
annual or quarterly report of the Company, and such other reports and 
documents of the Company and other information in the possession of or 
reasonably obtainable by the Company as the Holder may reasonably request in 
availing itself of any rule or regulation of the Commission allowing the 
Holder to sell any such securities without registration.

     1.13     Transfer of Registration Rights.  The rights to cause the 
Company to register securities granted Holders under Sections 1.5 and 1.6 may 
be assigned to a transferee or assignee reasonably acceptable to the Company 
in connection with any transfer or assignment of Registrable Securities by the 
Holder, provided that (a) such transfer may otherwise be effected in 
accordance with applicable securities laws and Section 1.3 and 1.4, and (b) 
such assignee or transferee acquires at least 100,000 shares of Registrable 
Securities.

     1.14     Standoff Agreement.  In connection with any public offering of 
the Company's securities, the Holder agrees, upon request of the Company or 
the underwriters managing any underwritten offering of the Company's 
securities, not to sell, make any short sale of, loan, grant any option for 
the purchase of, or otherwise dispose of any Registrable Securities (other 
than those included in the registration) without the prior written consent of 
the Company or such underwriters, as the case may be, for such period of time 
(not to exceed one hundred eighty (180) days) from the effective date of such 
registration as may be requested by the underwriters; provided that the 
officers and directors of the Company who own stock of the Company also agree 
to such restrictions.

     1.15     Termination of Registration Rights.  The registration rights 
granted pursuant to Section 1 shall terminate as to each Holder at such time 
as all Registrable Securities held by such Holder may, in the opinion of 
counsel to the Company (which opinion shall be addressed and rendered to 
Holder), be sold within a given three month period pursuant to Rule 144 or any 
other applicable exemption that allows for a resale free of registration.

SECTION 2

Right of First Refusal

     2.1     Grant of Right of First Refusal.  Subject to compliance with all 
applicable federal and state securities laws, the Company grants to the 
Holders the right of first refusal to purchase, pro rata, all or any part of 
New Securities (as defined in this Section 2) which the Company may, from time 
to time after the date of this Agreement, propose to sell and issue.  A pro 
rata share, for purposes of this right of first refusal, is the ratio that the 
sum of the number of shares of Conversion Stock then held by a Purchaser bears 
to the total outstanding Common Stock of the Company (assuming conversion of 
all convertible securities and the exercise of all outstanding options and 
warrants).

     2.2     Definition of New Securities.  Except as set forth below, "New 
Securities" shall mean any shares of capital stock of the Company, including 
Common Stock and Preferred Stock, whether now authorized or not, and rights, 
options or warrants to purchase said shares of Common Stock or Preferred 
Stock, and securities of any type whatsoever that are, or may become, 
convertible into said shares of Common Stock or Preferred Stock.  
Notwithstanding the foregoing, "New Securities" does not include (i) the 
Preferred Stock, the Warrants or the Conversion Stock, (ii) securities offered 
to the public generally pursuant to a registration statement under the 
Securities Act, (iii) securities issued pursuant to the acquisition of another 
corporation by the Company by merger, purchase of all or substantially all of 
the assets or other reorganization, (iv) securities issuable upon exercise or 
conversion of currently outstanding securities, (v) securities issued in 
connection with any stock split, stock dividend or recapitalization by the 
Company, (vi) securities issued to the Company's employees, officers, 
directors, and consultants pursuant to any arrangement approved by the Board 
of Directors of the Company, and (vii) securities issued to research or 
development collaborators or issued to banks or other institutional lenders or 
lessors in connection with capital asset leases or borrowings for the 
acquisition of capital assets, pursuant to any arrangement approved by the 
Board of Directors of the Company (including securities issued upon exercise 
or conversion of any such securities).

     2.3     Notice of Intent to Issue New Securities; Notice Period.  In the 
event the Company proposes to undertake an issuance of New Securities, it 
shall give each Purchaser written notice of its intention, describing the type 
of New Securities and the price and terms upon which the Company proposes to 
issue the same.  Each Purchaser shall have 15 days from the date of receipt of 
any such notice to agree to purchase up to its pro rata share of such New 
Securities for the price and upon the terms specified in the notice by giving 
written notice to the Company and stating therein the quantity of New 
Securities to be purchased.

     2.4     Offers to Third Parties.  In the event a Purchaser fails to 
exercise the right of first refusal within said 15 day period, the Company 
shall have 90 days thereafter to sell or enter into an agreement (pursuant to 
which the sale of New Securities covered thereby shall be closed, if at all, 
within 60 days from the date of said agreement) to sell the New Securities not 
elected to be purchased by the Purchaser at the price and upon the terms no 
more favorable to the Holders of such securities than specified in the 
Company's notice.  In the event the Company has not sold the New Securities or 
entered into an agreement to sell the New Securities in accordance with the 
foregoing within 60 days from the date of said agreement, the Company shall 
not thereafter issue or sell any New Securities without first offering such 
securities in the manner provided above.

     2.5     Assignment.  The right of first refusal granted under this 
Agreement is not assignable except by each of such Holders to any affiliated 
partnership or corporation or to a partner or retired partner of such S 
Purchaser or affiliated partnership or corporation.

     2.6     Termination of Right of First Refusal.  The right of first 
refusal granted under this Agreement shall terminate upon the first to occur 
of the following: 

                    (i)     if a Purchaser at any time holds less than 500,000 
shares of Conversion Stock (appropriately adjusted for any stock split, stock 
dividend or any other recapitalization), the right of first refusal shall 
terminate as to such Purchaser;

                    (ii)     if a Purchaser converts or has at any time 
converted all of the Preferred Stock owned by such Purchaser, the right of 
first refusal shall terminate as to such Purchaser; 
                    (iii)     the liquidation, dissolution or indefinite 
cessation of business operations of the Company; or

                    (iv)     the execution by the Company of a general 
assignment for the benefit of creditors or the appointment of a receiver or 
trustee to take possession of the property and assets of the Company.

Preferred Stock may, with the Company's prior written consent, waive, modify 
or amend on behalf of all holders, any provisions hereof.

     3.5     Notices, etc.  All notices and other communications required or 
permitted hereunder shall be in writing and shall be mailed by registered or 
certified mail, postage prepaid, or otherwise delivered by hand or by 
messenger, addressed (a) if to a Purchaser, at such Purchaser's address, as 
shown on the stock records of the Company, or at such other address as such

for the deposit of the United States mail, addressed and mailed as aforesaid.

     3.6     Delays or Omissions.  Except as expressly provided herein, no 
delay or omission to exercise any right, power or remedy accruing to any party 
to this Agreement upon any breach or default of any other party under this 
Agreement, shall impair any such right, power or remedy of such nondefaulting 
party nor shall it be construed to be a waiver of any such breach or default, 
or an acquiescence therein, or of or in any similar breach or default 
thereafter occurring; nor shall any waiver of any single breach or default be 
deemed a waiver of any other breach or default theretofore or thereafter 
occurring.  Any waiver, permit, consent or approval of any kind or character 
on the part of any party of any breach or default under this Agreement, or any 
waiver on the part of any holder of any provisions or conditions of this 
Agreement, must be in writing and shall be effective only to the extent

     AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT


This Amended and Restated Registration Rights Agreement ("Agreement"), dated 
as of February 26, 1999, by and among Superconductor Technologies Inc., a 
Delaware corporation, with its headquarters located at 460 Ward Drive, Suite 
F, Santa Barbara, California 93111-2310 (the "Company"), and each of the 
undersigned (together with their respective affiliates and any assignee or 
transferee of all of their respective rights hereunder, the "Initial 
Investors") pursuant to the Exchange Agreement by and among the parties hereto 
and the holders of the Company's Series A-2 and Series A-3 Preferred Stock of 
even date herewith (the "Exchange Agreement"). 

BACKGROUND

     A.     The Company and the Initial Investors entered into that certain 
Registration Rights Agreement dated as of September 2, 1998 (the "Existing 
Agreement"), which established certain terms and conditions upon which the 
Company's Series B Preferred Stock and certain warrants are held by the 
Initial Investors, as set forth more particularly in the Existing Agreement.

B.     In connection with the Exchange Agreement, the Company and the Initial 
Investors have agreed, upon the terms and subject to the conditions contained 
therein, to exchange the shares of the Company's Series B Convertible 
Preferred Stock and related warrants held by the Initial Investors for shares 
of the Company's Series B-1 Convertible Preferred Stock (the "Preferred 
Stock") and related warrants that are convertible into shares (the "Conversion 
Shares") of the Company's common stock, par value $.001 per share (the "Common 
Stock"), upon the terms and subject to the limitations and conditions set 
forth in the Certificate of Designations, Rights, Preferences, Privileges and 
Restrictions with respect to the Preferred Stock (the "Certificate of 
Designation").

C.     To induce the Initial Investors to execute and deliver the Exchange 
Agreement, the Company has agreed to provide certain registration rights under 
the Securities Act of 1933, as amended, and the rules and regulations 
thereunder, or any similar successor statute (collectively, the "1933 Act"), 
and applicable state securities laws;

D.     The Company and the Initial Investors desire to amend and restate the 
Existing Agreement in its entirety, as set forth herein, to make the holders 
of the Company's Series B-1 Preferred Stock party thereto.




NOW, THEREFORE, the parties amend and restate the Existing Agreemenet in its 
entirety to read as follows:

1.     DEFINITIONS.

a.     As used in this Agreement, the following terms shall have the following 
meanings:

(i)     "Investors" means the Initial Investors and any transferee or assignee 
who becomes bound by the provisions of this Agreement in accordance with 
Section 9 hereof.

(ii)     "register," "registered," and "registration" refer to a registration 
effected by preparing and filing a Registration Statement or Statements in 
compliance with the 1933 Act and pursuant to Rule 415 under the 1933 Act or 
any successor rule providing for offering securities on a continuous basis 
("Rule 415"), and the declaration or ordering of effectiveness of such 
Registration Statement by the United States Securities and Exchange Commission 
(the "SEC").

(iii)     "Registrable Securities" means the Conversion Shares (including any 
additional shares that may be issued pursuant to the Certificate of 
Designation) and Warrant Shares issued or issuable and any shares of capital 
stock issued or issuable as a dividend on or in exchange for or otherwise with 
respect to any of the foregoing, provided, however, that such securities shall 
only be treated as Registrable Securities if and so long as they have not been 
(A) sold to or through a broker or dealer or underwriter in a public 
distribution or a public securities transaction, or (B) sold or are, in the 
opinion of counsel for the Company, available for sale in a single transaction 
exempt from the registration and prospectus delivery requirements of the 1933 
Act so that all transfer restrictions and restrictive legends with respect 
thereto are removed upon the consummation such sale.

(iv)     "Registration Statement" means a registration statement of the 
Company under the 1933 Act.

b.     Capitalized terms used herein and not otherwise defined herein shall 
have the respective meanings set forth in the Securities Purchase Agreement 
(the "Securities Purchase Agreement") dated as of September 2, 1999 entered 
into between the Company and the purchasers identified therein.

2.     REGISTRATION.

a.     Mandatory Registration.  The Company shall prepare, and, on or prior to 
the date which is sixty (60) days after the date of the Closing under and as 
defined in the Exchange Agreement (the "Closing Date"), file with the SEC a 
Registration Statement on Form S-3 (or, if Form S-3 is not then available, on 
such form of Registration Statement as is then available to effect a 
registration of the Registrable Securities) covering the resale of the 
Registrable Securities underlying the Preferred Stock and Warrants issued or 
issuable pursuant to the Securities Purchase Agreement, which Registration 
Statement, to the extent allowable under the 1933 Act and the Rules 
promulgated thereunder (including Rule 416),  shall state that such 
Registration Statement also covers such indeterminate number of additional 
shares of Common Stock as may become issuable upon conversion of the Preferred 
Stock and exercise of the Warrants (i) to prevent dilution resulting from 
stock splits, stock dividends or similar transactions or (ii) by reason of 
changes in the Conversion Price of the Preferred Stock in accordance with the 
terms thereof or the exercise price of the Warrants in accordance with the 
terms thereof.  The number of shares of Common Stock initially included in 
such Registration Statement shall be no less than the sum of the number of 
Conversion Shares and Warrant Shares that are then issuable upon conversion of 
the Preferred Stock and the exercise of the Warrants, without regard to any 
limitation on the Investor's ability to convert the Preferred Stock or 
exercise the Warrants.  The Company acknowledges that the number of shares 
initially included in the Registration Statement represents a good faith 
estimate of the maximum number of shares issuable upon conversion of the 
Preferred Stock and exercise of the Warrants.

           b.     Payments by the Company.  The Company shall use its best 
efforts to obtain effectiveness of the Registration Statement as soon as 
practicable.  If (i) the Registration Statement(s) covering the Registrable 
Securities required to be filed by the Company pursuant to Section 2(a) hereof 
is not filed within sixty (60) days after the Closing Date or declared 
effective by the SEC within one hundred twenty (120) days after the Closing 
Date or if, after the Registration Statement has been declared effective by 
the SEC, sales cannot be made pursuant to the Registration Statement (except 
as a result of an Allowed Delay (as defined in section 3(f)), or (ii) the 
Common Stock is not listed or included for quotation on the Nasdaq National 
Market ("Nasdaq"), the Nasdaq SmallCap Market ("Nasdaq SmallCap"), the New 
York Stock Exchange (the "NYSE") or the American Stock Exchange (the "AMEX") 
after being so listed or included for quotation, then the Company will make 
payments to the Investors in such amounts and at such times as shall be 
determined pursuant to this Section 2(b) as partial relief for the damages to 
the Investors by reason of any such delay in or reduction of their ability to 
sell the Registrable Securities (which remedy shall not be exclusive of any 
other remedies available at law or in equity).  The Company shall not have any 
obligation to pay to the Investors any amounts provided for in this Section 
2(b) during an Allowed Delay.  The Company shall pay to each holder of the 
Preferred Stock or Registerable Securities an amount equal to the Purchase 
Price under and as defined in the Securities Purchase Agreement paid in 
respect of such Preferred Stock (and, in the case of holders of Registerable 
Securities, the purchase price for the Preferred Stock from which such 
Registerable Securities were converted) ("Aggregate Share Price") multiplied 
by the Applicable Percentage (as defined below) multiplied by the number of 
months (without duplication), prorated for partial months during (1) which the 
events described in clauses (i) or (ii) above have occurred and are 
continuing, (2) sales cannot be made pursuant to the Registration Statement 
after the Registration Statement has been declared effective (including, 
without limitation, when sales cannot be made by reason of the Company's 
failure to properly supplement or amend the prospectus included therein in 
accordance with the terms of this Agreement, but excluding any days during an  
Allowed Delay (as defined in Section 3(f)), or (3) that the Common Stock is 
not listed or included for quotation on the Nasdaq, Nasdaq SmallCap, NYSE or 
AMEX or that trading thereon is halted after the Registration Statement has 
been declared effective.  The term "Applicable Percentage" means 2 hundredths 
(.02).   Such amounts shall be paid in cash or, at the Company=s option, paid 
in shares of Preferred Stock, calculated based on the Purchase Price 
applicable to such shares and thereafter be convertible into Common Stock at 
the "Conversion Price" (as defined in the Certificate of Designation) in 
accordance with the terms of the Preferred Stock.  Any shares of Common Stock 
issued upon conversion of such amounts shall be Registrable Securities.  
Payments of cash pursuant hereto shall be made within ten (10) days after the 
end of each period that gives rise to such obligation, provided that, if any 
such period extends for more than thirty (30) days, interim payments shall be 
made for each such thirty (30) day period.  

c.     Piggy-Back Registrations.  Subject to the last sentence of this Section 
2(c), if at any time prior to the expiration of the Registration Period (as 
hereinafter defined) the Company shall file with the SEC a Registration 
Statement relating to an offering for its own account or the account of others 
under the 1933 Act of any of its equity securities (other than on Form S-4 or 
Form S-8 or their then equivalents relating to equity securities to be issued 
solely in connection with any acquisition of any entity or business or equity 
securities issuable in connection with stock option or other employee benefit 
plans), the Company shall send to each Investor who is entitled to 
registration rights under this Section 2(c) written notice of such 
determination and, if within twenty (20) days after the effective date of such 
notice, such Investor shall so request in writing, the Company shall include 
in such Registration Statement all or any part of the Registrable Securities 
such Investor requests to be registered, except that if, in connection with 
any underwritten public offering for the account of the Company the managing 
underwriter(s) thereof shall impose a limitation on the number of shares of 
Common Stock which may be included in the Registration Statement because, in 
such underwriter(s)' judgment, marketing or other factors dictate such 
limitation is necessary to facilitate public distribution, then the Company 
shall be obligated to include in such Registration Statement only such limited 
portion of the Registrable Securities with respect to which such Investor has 
requested inclusion hereunder as the underwriter shall permit. Any exclusion 
of Registrable Securities shall be made pro rata among the Investors seeking 
to include Registrable Securities in proportion to the number of Registrable 
Securities sought to be included by such Investors; provided, however, that 
the Company shall not exclude any Registrable Securities unless the Company 
has first excluded all outstanding securities, the holders of which are not 
entitled to inclusion of such securities in such Registration Statement or are 
not entitled to pro rata inclusion with the Registrable Securities; and 
provided, further, however, that, after giving effect to the immediately 
preceding proviso, any exclusion of Registrable Securities shall be made pro 
rata with holders of other securities having the right to include such 
securities in the Registration Statement other than holders of securities 
entitled to inclusion of their securities in such Registration Statement by 
reason of demand registration rights.  No right to registration of Registrable 
Securities under this Section 2(c) shall be construed to limit any 
registration required under Section 2(a) hereof.  If an offering in connection 
with which an Investor is entitled to registration under this Section 2(c) is 
an underwritten offering, then each Investor whose Registrable Securities are 
included in such Registration Statement shall, unless otherwise agreed by the 
Company, offer and sell such Registrable Securities in an underwritten 
offering using the same underwriter or underwriters and, subject to the 
provisions of this Agreement, on the same terms and conditions as other shares 
of Common Stock included in such underwritten offering.  Notwithstanding 
anything to the contrary set forth herein, the registration rights of the 
Investors pursuant to this Section 2(c) shall only be available in the event 
the Company fails to timely file, obtain effectiveness or maintain 
effectiveness of the Registration Statement to be filed pursuant to Section 
2(a) in accordance with the terms of this Agreement.

d.     Eligibility for Form S-3.  The Company represents and warrants that it 
meets the registrant eligibility and transaction requirements for the use of 
Form S-3 for registration of the sale by the Initial Investors and any other 
Investors of the Registrable Securities and the Company shall file all reports 
required to be filed by the Company with the SEC in a timely manner so as to 
maintain such eligibility for the use of Form S-3.

3.     OBLIGATIONS OF THE COMPANY.  

In connection with the registration of the Registrable Securities, the Company 
shall have the following obligations:

a.     The Company shall prepare promptly, and file with the SEC not later 
than sixty (60) days after the Closing Date, a Registration Statement with 
respect to the number of Registrable Securities provided in Section 2(a), and 
thereafter use its best efforts to cause such Registration Statement relating 
to Registrable Securities to become effective as soon as possible after the 
filing thereof, and keep the Registration Statement effective pursuant to Rule 
415 at all times until such date as is the earlier of (i) the date on which 
all of the Registrable Securities have been sold and (ii) the date on which 
the Registrable Securities (in the opinion of counsel to the Initial 
Investors) may be immediately sold without restriction (including without 
limitation as to volume by each holder thereof) without registration under the 
1933 Act (the "Registration Period").

b.     The Company shall prepare and file with the SEC such amendments 
(including post-effective amendments) and supplements to the Registration 
Statement and the prospectus used in connection with the Registration 
Statement as may be necessary to keep the Registration Statement effective at 
all times during the Registration Period, and, during such period, comply with 
the provisions of the 1933 Act with respect to the disposition of all 
Registrable Securities of the Company covered by the Registration Statement 
until such time as all of such Registrable Securities have been disposed of in 
accordance with the intended methods of disposition by the seller or sellers 
thereof as set forth in the Registration Statement.  In the event the number 
of shares available under a Registration Statement filed pursuant to this 
Agreement is insufficient to cover all of the Registrable Securities issued or 
issuable upon conversion of the Preferred Stock and exercise of the Warrants, 
the Company shall amend the Registration Statement, or file a new Registration 
Statement (on the short form available therefore, if applicable), or both, so 
as to cover all of the Registrable Securities, in each case, as soon as 
practicable, but in any event within twenty (20) business days after the 
necessity therefor arises (based on the market price of the Common Stock and 
other relevant factors on which the Company reasonably elects to rely).  The 
Company shall use its commercially reasonable efforts to cause such amendment 
and/or new Registration Statement to become effective as soon as practicable 
following the filing thereof.  The provisions of Section 2(c) above shall be 
applicable with respect to such obligation, with the sixty (60) or one hundred 
twenty (120) days running from the day after the date on which the Company 
reasonably first determines (or reasonably should have determined) the need 
therefor.

c.     The Company shall furnish to each Investor whose Registrable Securities 
are included in the Registration Statement (i) promptly after the same is 
prepared and publicly distributed, filed with the SEC, or received by the 
Company, one copy of the Registration Statement and any amendment thereto, 
each preliminary prospectus and prospectus and each amendment or supplement 
thereto and (ii) such number of copies of a prospectus, including a preliminary 
prospectus, and all amendments and supplements thereto and such other 
documents as such Investor may reasonably request in order to facilitate the 
disposition of the Registrable Securities owned by such Investor.  The Company 
will immediately notify each Investor by facsimile of the effectiveness of the 
Registration Statement or any post-effective amendment.  The Company will 
promptly file an acceleration request as soon as practicable following the 
resolution or clearance of all SEC comments or, if applicable, following 
notification by the SEC that the Registration Statement or any amendment 
thereto will not be subject to review.

d.     The Company shall use reasonable efforts to (i) register and qualify 
the Registrable Securities covered by the Registration Statement under such 
other securities or "blue sky" laws of such jurisdictions in the United States 
as the Investors who hold a majority in interest of the Registrable Securities 
being offered reasonably request, (ii) prepare and file in those jurisdictions 
such amendments (including post-effective amendments) and supplements to such 
registrations and qualifications as may be necessary to maintain the 
effectiveness thereof during the Registration Period, (iii) take such other 
actions as may be necessary to maintain such registrations and qualifications 
in effect at all times during the Registration Period, and (iv) take all other 
actions reasonably necessary or advisable to qualify the Registrable 
Securities for sale in such jurisdictions; provided, however, that the Company 
shall not be required in connection therewith or as a condition thereto to (a) 
qualify to do business in any jurisdiction where it would not otherwise be 
required to qualify but for this Section 3(d), (b) subject itself to general 
taxation in any such jurisdiction, (c) file a general consent to service of 
process in any such jurisdiction, (d) provide any undertakings that cause the 
Company undue expense or burden, or (e) make any change in its charter or 
bylaws.

e.     In the event Investors who hold a majority-in-interest of the 
Registrable Securities being offered in the offering select underwriters for 
the offering, the Company shall enter into and perform its obligations under 
an underwriting agreement, in usual and customary form, including, without 
limitation, customary indemnification and contribution obligations, with the 
underwriters of such offering.  

f.     As promptly as practicable after becoming aware of such event, the 
Company shall notify each Investor of (x) the issuance by the SEC of a stop 
order suspending the effectiveness of the Registration Statement, (y) the 
happening of any event, of which the Company has knowledge, as a result of 
which the prospectus included in the Registration Statement, as then in 
effect, includes an untrue statement of a material fact or omission to state a 
material fact required to be stated therein or necessary to make the 
statements therein not misleading, (z) the occurrence or existence of any 
pending corporate development that, in the reasonable discretion of the 
Company, makes it appropriate to suspend the availability of the Registration 
Statement and use its best efforts promptly to prepare a supplement or 
amendment to the Registration Statement to correct such untrue statement or 
omission, and deliver such number of copies of such supplement or amendment to 
each Investor as such Investor may reasonably request; provided that, for not 
more than twenty (20) consecutive trading days (or a total of not more than 
thirty (30) trading days in any twelve (12) month period) (or 60 trading days 
in any 12 month period, in the case of an event described in clause (z) above 
that arises from an acquisition or a probable acquisition or financing, 
recapitalization, business combination or other similar transaction), the 
Company may delay the disclosure of material non-public information concerning 
the Company (as well as prospectus or Registration Statement updating) the 
disclosure of which at the time is not, in the good faith opinion of the 
Company, the best interests of the Company (an "Allowed Delay"); provided, 
further, that the Company shall promptly (i) notify the Investors in writing 
of the existence of (but in no event, without the prior written consent of an 
Investor, shall the Company disclose to such investor any of the facts or 
circumstances regarding) material non-public information giving rise to an 
Allowed Delay and (ii) advise the Investors in writing to cease all sales 
under the Registration Statement until the end of the Allowed Delay. Upon 
expiration of the Allowed Delay, the Company shall again be bound by the first 
sentence of this Section 3(f) with respect to the information giving rise 
thereto, and shall be obligated to pay to the Investors any amounts provided 
for in Section 2(b).

g.     The Company shall use its best efforts to prevent the issuance of any 
stop order or other suspension of effectiveness of a Registration Statement, 
and, if such an order is issued, to obtain the withdrawal of such order at the 
earliest possible moment and to notify each Investor who holds Registrable 
Securities being sold (or, in the event of an underwritten offering, the 
managing underwriters) of the issuance of such order and the resolution 
thereof. 

h.     The Company shall permit a single firm of counsel designated by the 
Initial Investors to review the Registration Statement and all amendments and 
supplements thereto (as well as all requests for acceleration or effectiveness 
thereof) a reasonable period of time prior to their filing with the SEC, and 
not file any document in a form to which such counsel reasonably objects and 
will not request acceleration of the Registration Statement without prior 
notice to such counsel.  The sections of the Registration Statement covering 
information with respect to the Investors, the Investor's beneficial ownership 
of securities of the Company or the Investors intended method of disposition 
of Registrable Securities shall conform to the information provided to the 
Company by each of the Investors.

i.     The Company shall make generally available to its security holders as 
soon as practical, but not later than ninety (90) days after the close of the 
period covered thereby, an earnings statement (in form complying with the 
provisions of Rule 158 under the 1933 Act) covering a twelve-month period 
beginning not later than the first day of the Company's fiscal quarter next 
following the effective date of the Registration Statement.

j.     At the request of any Investor, the Company shall furnish, on the date 
that Registrable Securities are delivered to an underwriter, if any, for sale 
in connection with the Registration Statement or, if such securities are not 
being sold by an underwriter, on the date of effectiveness thereof (i) an 
opinion, dated as of such date, from counsel representing the Company for 
purposes of such Registration Statement, in form, scope and substance as is 
customarily given in an underwritten public offering, addressed to the 
underwriters, if any, and the Investors and (ii) a letter, dated such date, 
from the Company's independent certified public accountants in form and 
substance as is customarily given by independent certified public accountants 
to underwriters in an underwritten public offering, addressed to the 
underwriters, if any, and the Investors.

k.     The Company shall make available for inspection during normal business 
hours by (i) any Investor and (ii) one firm of attorneys and one firm of 
accountants or other agents retained by the Initial Investors, (collectively, 
the "Inspectors") all pertinent financial and other records, and pertinent 
corporate documents and properties of the Company (collectively, the 
"Records"), as shall be reasonably deemed necessary by each Inspector to 
enable each Inspector to exercise its due diligence responsibility, and cause 
the Company's officers, directors and employees to supply all information 
which any Inspector may reasonably request for purposes of such due diligence; 
provided, however, that each Inspector shall hold in confidence and shall not 
make any disclosure (except to an Investor) of any Record or other information 
which the Company determines in good faith to be confidential, and of which 
determination the Inspectors are so notified, unless (a) the disclosure of 
such Records is necessary to avoid or correct a misstatement or omission in 
any Registration Statement, (b) the release of such Records is ordered 
pursuant to a subpoena or other order from a court or government body of 
competent jurisdiction, or (c) the information in such Records has been made 
generally available to the public other than by disclosure in violation of 
this or any other agreement.  The Company shall not be required to disclose 
any confidential information in such Records to any Inspector until and unless 
such Inspector shall have entered into confidentiality agreements (in form and 
substance satisfactory to the Company) with the Company with respect thereto, 
substantially in the form of this Section 3(k).  Each Investor agrees that it 
shall, upon learning that disclosure of such Records is sought in or by a 
court or governmental body of competent jurisdiction or through other means, 
give prompt notice to the Company and allow the Company, at its expense, to 
undertake appropriate action to prevent disclosure of, or to obtain a 
protective order for, the Records deemed confidential.  Nothing herein (or in 
any other confidentiality agreement between the Company and any Investor) 
shall be deemed to limit the Investor's ability to sell Registrable Securities 
in a manner which is otherwise consistent with applicable laws and 
regulations. 

l.     The Company shall hold in confidence and not make any disclosure of 
information concerning an Investor provided to the Company unless (i) 
disclosure of such information is necessary to comply with federal or state 
securities laws, (ii) the disclosure of such information is necessary to avoid 
or correct a misstatement or omission in any Registration Statement, (iii) the 
release of such information is ordered pursuant to a subpoena or other order 
from a court or governmental body of competent jurisdiction, or (iv) such 
information has been made generally available to the public other than by 
disclosure in violation of this or any other agreement.  The Company agrees 
that it shall, upon learning that disclosure of such information concerning an 
Investor is sought in or by a court or governmental body of competent 
jurisdiction or through other means, give prompt notice to such Investor prior 
to making such disclosure, and allow the Investor, at its expense, to 
undertake appropriate action to prevent disclosure of, or to obtain a 
protective order for, such information.

m.     The Company shall (i) cause all the Registrable Securities covered by 
the Registration Statement to be listed on each national securities exchange 
on which securities of the same class or series issued by the Company are then 
listed, if any, if the listing of such Registrable Securities is then 
permitted under the rules of such exchange, or (ii) secure the designation and 
quotation, of all the Registrable Securities covered by the Registration 
Statement on the Nasdaq or, if not eligible for the Nasdaq on the Nasdaq 
SmallCap and, without limiting the generality of the foregoing, to arrange for 
at least two market makers to register with the National Association of 
Securities Dealers, Inc. ("NASD") as such with respect to such Registrable 
Securities.

n.     The Company shall provide a transfer agent and registrar, which may be 
a single entity, for the Registrable Securities not later than the effective 
date of the Registration Statement.
o.     The Company shall cooperate with the Investors who hold Registrable 
Securities being offered and the managing underwriter or underwriters, if any, 
to facilitate the timely preparation and delivery of certificates (not bearing 
any restrictive legends) representing Registrable Securities to be offered 
pursuant to the Registration Statement and enable such certificates to be in 
such denominations or amounts, as the case may be, as the managing underwriter 
or underwriters, if any, or the Investors may reasonably request and 
registered in such names as the managing underwriter or underwriters, if any, 
or the Investors may request, and, within five (5) business days after a 
Registration Statement which includes Registrable Securities is ordered 
effective by the SEC, the Company shall deliver, and shall cause legal counsel 
selected by the Company to deliver, to the transfer agent for the Registrable 
Securities (with copies to the Investors whose Registrable Securities are 
included in such Registration Statement) an instruction in the form attached 
hereto as Exhibit 1 and an opinion of such counsel in the form attached hereto 
as Exhibit 2.

p.     Except for registration rights previously disclosed to the Buyers prior 
to the execution of this Agreement, from and after the date of this Agreement, 
the Company shall not, and shall not agree to, allow the holders of any 
securities of the Company to include any of their securities in any 
Registration Statement under Section 2(a) hereof or any amendment or 
supplement thereto under Section 3(b) hereof without the consent of the 
holders of a majority-in-interest of the Registrable Securities.

q.     The Company shall take all other reasonable actions necessary to 
expedite and facilitate disposition by the Investors of Registrable Securities 
pursuant to the Registration Statement.

4.     OBLIGATIONS OF THE INVESTORS.

In connection with the registration of the Registrable Securities, the 
Investors shall have the following obligations:

a.     It shall be a condition precedent to the obligations of the Company to 
complete the registration pursuant to this Agreement with respect to the 
Registrable Securities of a particular Investor that such Investor shall 
furnish to the Company such information regarding itself, the Registrable 
Securities held by it and the intended method of disposition of the 
Registrable Securities held by it as shall be reasonably required to effect 
the registration of such Registrable Securities and shall execute such 
documents in connection with such registration as the Company may reasonably 
request.  At least three (3) business days prior to the first anticipated 
filing date of the Registration Statement, the Company shall notify each 
Investor of the information the Company requires from each such Investor. 

b.     Each Investor, by such Investor's acceptance of the Registrable 
Securities, agrees to cooperate with the Company as reasonably requested by 
the Company in connection with the preparation and filing of the Registration 
Statement hereunder, unless such Investor has notified the Company in writing 
of such Investor's election to exclude all of such Investor's Registrable 
Securities from the Registration Statement.

c.     In the event Investors holding a majority-in-interest of the 
Registrable Securities being registered (with the approval of the Initial 
Investors) determine to engage the services of an underwriter, each Investor 
agrees to enter into and perform such Investor's obligations under an 
underwriting agreement, in usual and customary form, including, without 
limitation, customary indemnification and contribution obligations, with the 
managing underwriter of such offering and take such other actions as are 
reasonably required in order to expedite or facilitate the disposition of the 
Registrable Securities, unless such Investor has notified the Company in 
writing of such Investor's election to exclude all of such Investor's 
Registrable Securities from the Registration Statement.

d.     Each Investor agrees that, upon receipt of any notice from the Company 
of the happening of any event of the kind described in Section 3(f) or 3(g), 
such Investor will immediately discontinue disposition of Registrable 
Securities pursuant to the Registration Statement covering such Registrable 
Securities until such Investor's receipt of the copies of the supplemented or 
amended prospectus contemplated by Section 3(f) or 3(g) and, if so directed by 
the Company, such Investor shall deliver to the Company (at the expense of the 
Company) or destroy (and deliver to the Company a certificate of destruction) 
all copies in such Investor's possession, of the prospectus covering such 
Registrable Securities current at the time of receipt of such notice.

e.     No Investor may participate in any underwritten registration hereunder 
unless such Investor (i) agrees to sell such Investor's Registrable Securities 
on the basis provided in any underwriting arrangements in usual and customary 
form entered into by the Company, (ii) completes and executes all 
questionnaires, powers of attorney, indemnities, underwriting agreements and 
other documents reasonably required under the terms of such underwriting 
arrangements, and (iii) agrees to pay its pro rata share of all underwriting 
discounts and commissions and any expenses in excess of those payable by the 
Company pursuant to Section 5 below.

5.     EXPENSES OF REGISTRATION.

All reasonable expenses, other than underwriting discounts and commissions, 
incurred in connection with registrations, filings or qualifications pursuant 
to Sections 2 and 3, including, without limitation, all registration, listing 
and qualification fees, printers and accounting fees, the fees and 
disbursements of counsel for the Company, and the reasonable fees and 
disbursements of one counsel selected by the Initial Investors pursuant to 
Sections 2(b) and 3(h) hereof shall be borne by the Company.

     6.     INDEMNIFICATION.  

In the event any Registrable Securities are included in a Registration 
Statement under this Agreement:

a.     To the extent permitted by law, the Company will indemnify, hold 
harmless and defend (i) each Investor who holds such Registrable Securities, 
(ii) the directors, officers, partners, employees, agents and each person who 
controls any Investor within the meaning of the 1933 Act or the Securities 
Exchange Act of 1934, as amended (the "1934 Act"), if any, (iii) any 
underwriter (as defined in the 1933 Act) for the Investors, and (iv) the 
directors, officers, partners, employees and each person who controls any such 
underwriter within the meaning of the 1933 Act or the 1934 Act, if any (each, 
an "Indemnified Person"), against any joint or several losses, claims, 
damages, liabilities or expenses (collectively, together with actions, 
proceedings or inquiries by any regulatory or self-regulatory organization, 
whether commenced or threatened, in respect thereof, "Claims") to which any of 
them may become subject insofar as such Claims arise out of or are based upon: 
(i) any untrue statement or alleged untrue statement of a material fact in a 
Registration Statement or the omission or alleged omission to state therein a 
material fact required to be stated or necessary to make the statements 
therein not misleading; (ii) any untrue statement or alleged untrue statement 
of a material fact contained in any preliminary prospectus if used prior to 
the effective date of such Registration Statement, or contained in the final 
prospectus (as amended or supplemented, if the Company files any amendment 
thereof or supplement thereto with the SEC) or the omission or alleged 
omission to state therein any material fact necessary to make the statements 
made therein, in light of the circumstances under which the statements therein 
were made, not misleading; or (iii) any violation or alleged violation by the 
Company of the 1933 Act, the 1934 Act, any other law, including, without 
limitation, any state securities law, or any rule or regulation thereunder 
relating to the offer or sale of the Registrable Securities (the matters in 
the foregoing clauses (i) through (iii) being, collectively, "Violations").  
Subject to the restrictions set forth in Section 6(c) with respect to the 
number of legal counsel, the Company shall reimburse the Indemnified Person, 
promptly as such expenses are incurred and are due and payable, for any 
reasonable legal fees or other reasonable expenses incurred by them in 
connection with investigating or defending any such Claim.  Notwithstanding 
anything to the contrary contained herein, the indemnification agreement 
contained in this Section 6(a): (i) shall not apply to a Claim arising out of 
or based upon a Violation which occurs in reliance upon and in conformity with 
information furnished in writing to the Company by any Indemnified Person or 
underwriter for such Indemnified Person expressly for use in connection with 
the preparation of the Registration Statement or any such amendment thereof or 
supplement thereto, if such prospectus was timely made available by the 
Company pursuant to Section 3(c) hereof; (ii) shall not apply to amounts paid 
in settlement of any Claim if such settlement is effected without the prior 
written consent of the Company, which consent shall not be unreasonably 
withheld; and (iii) with respect to any preliminary prospectus, shall not 
inure to the benefit of any Indemnified Person if the untrue statement or 
omission of material fact contained in the preliminary prospectus was 
corrected on a timely basis in the prospectus, as then amended or 
supplemented, such corrected prospectus was timely made available by the 
Company pursuant to Section 3(c) hereof, and the Indemnified Person was 
promptly advised in writing not to use the incorrect prospectus prior to the 
use giving rise to a Violation and such Indemnified Person, notwithstanding 
such advice, used it.  Such indemnity shall remain in full force and effect 
regardless of any investigation made by or on behalf of the Indemnified Person 
and shall survive the transfer of the Registrable Securities by the Investors 
pursuant to Section 9.

b.     In connection with any Registration Statement in which an Investor is 
participating, each such Investor agrees severally and not jointly to 
indemnify, hold harmless and defend, to the same extent and in the same manner 
set forth in Section 6(a), the Company, each of its directors, each of its 
officers who signs the Registration Statement, each person, if any, who 
controls the Company within the meaning of the 1933 Act or the 1934 Act, any 
underwriter and any other stockholder selling securities pursuant to the 
Registration Statement or any of its directors or officers or any person who 
controls such stockholder or underwriter within the meaning of the 1933 Act or 
the 1934 Act (collectively and together with an Indemnified Person, an 
"Indemnified Party"), against any Claim to which any of them may become 
subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim 
arises out of or is based upon any Violation by such Investor, in each case to 
the extent (and only to the extent) that such Violation occurs in reliance 
upon and in conformity with written information furnished to the Company by 
such Investor expressly for use in connection with such Registration 
Statement; and subject to Section 6(c) such Investor will reimburse any legal 
or other expenses (promptly as such expenses are incurred and are due and 
payable) reasonably incurred by them in connection with investigating or 
defending any such Claim; provided, however, that the indemnity agreement 
contained in this Section 6(b) shall not apply to amounts paid in settlement 
of any Claim if such settlement is effected without the prior written consent 
of such Investor, which consent shall not be unreasonably withheld; provided, 
further, however, that the Investor shall be liable under this Agreement 
(including this Section 6(b) and Section 7) for only that amount as does not 
exceed the net proceeds to such Investor as a result of the sale of 
Registrable Securities pursuant to such Registration Statement.  Such 
indemnity shall remain in full force and effect regardless of any 
investigation made by or on behalf of such Indemnified Party and shall survive 
the transfer of the Registrable Securities by the Investors pursuant to 
Section 9. Notwithstanding anything to the contrary contained herein, the 
indemnification agreement contained in this Section 6(b) with respect to any 
preliminary prospectus shall not inure to the benefit of any Indemnified Party 
if the untrue statement or omission of material fact contained in the 
preliminary prospectus was corrected on a timely basis in the prospectus, as 
then amended or supplemented.

c.     Promptly after receipt by an Indemnified Person or Indemnified Party 
under this Section 6 of notice of the commencement of any action (including 
any governmental action), such Indemnified Person or Indemnified Party shall, 
if a Claim in respect thereof is to be made against any indemnifying party 
under this Section 6, deliver to the indemnifying party a written notice of 
the commencement thereof, and the indemnifying party shall have the right to 
participate in, and, to the extent the indemnifying party so desires, jointly 
with any other indemnifying party similarly noticed, to assume control of the 
defense thereof with counsel mutually satisfactory to the indemnifying party 
and the Indemnified Person or the Indemnified Party, as the case may be; 
provided, however, that an Indemnified Person or Indemnified Party shall have 
the right to retain its own counsel with the fees and expenses to be paid by 
the indemnifying party, if, in the reasonable opinion of counsel retained by 
the indemnifying party, the representation by such counsel of the Indemnified 
Person or Indemnified Party and the indemnifying party would be inappropriate 
due to actual or potential differing interests between such Indemnified Person 
or Indemnified Party and any other party represented by such counsel in such 
proceeding.  The indemnifying party shall pay for only one separate legal 
counsel for  the Indemnified Persons or the Indemnified Parties, as 
applicable, and such legal counsel shall be selected by Investors holding a 
majority-in-interest of the  Registrable Securities included in the 
Registration Statement to which the Claim relates (with the approval of a 
majority-in-interest of the Initial Investors), if the Investors are entitled 
to indemnification hereunder, or the Company, if the Company is entitled to 
indemnification hereunder, as applicable.  The failure to deliver written 
notice to the indemnifying party within a reasonable time of the commencement 
of any such action shall not relieve such indemnifying party of any liability 
to the Indemnified Person or Indemnified Party under this Section 6, except to 
the extent that the indemnifying party is actually prejudiced in its ability 
to defend such action.  The indemnification required by this Section 6 shall 
be made by periodic payments of the amount thereof during the course of the 
investigation or defense, as such expense, loss, damage or liability is 
incurred and is due and payable.

7.     CONTRIBUTION.  

To the extent any indemnification by an indemnifying party is prohibited or 
limited by law, the indemnifying party agrees to make the maximum contribution 
with respect to any amounts for which it would otherwise be liable under 
Section 6 to the fullest extent permitted by law; provided, however, that (i) 
no contribution shall be made under circumstances where the maker would not 
have been liable for indemnification under the fault standards set forth in 
Section 6, (ii) no seller of Registrable Securities guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall 
be entitled to contribution from any seller of Registrable Securities who was 
not guilty of such fraudulent misrepresentation, and (iii) contribution 
(together with any indemnification or other obligations under this Agreement) 
by any seller of Registrable Securities shall be limited in amount to the net 
amount of proceeds received by such seller from the sale of such Registrable 
Securities.

8.     REPORTS UNDER THE 1934 ACT.  

With a view to making available to the Investors the benefits of Rule 144 
promulgated under the 1933 Act or any other similar rule or regulation of the 
SEC that may at any time permit the investors to sell securities of the 
Company to the public without registration ("Rule 144"), the Company agrees 
to:

a.     make and keep public information available, as those terms are 
understood and defined in Rule 144;

b.     file with the SEC in a timely manner all reports and other documents 
required of the Company under the 1933 Act and the 1934 Act so long as the 
Company remains subject to such requirements (it being understood that nothing 
herein shall limit the Company's obligations under Section 4(c) of the 
Securities Purchase Agreement) and the filing of such reports and other 
documents is required for the applicable provisions of Rule 144; and

c.     furnish to each Investor so long as such Investor owns Registrable 
Securities, promptly upon request, (i) a copy of the most recent annual or 
quarterly report of the Company and such other reports and documents so filed 
by the Company, and (ii) such other information as may be reasonably requested 
to permit the Investors to sell such securities pursuant to Rule 144 without 
registration.

9.     ASSIGNMENT OF REGISTRATION RIGHTS.  

The rights under this Agreement shall be automatically assignable by the 
Investors to any transferee of all or any portion of Registrable Securities 
if: (i) the Investor agrees in writing with the transferee or assignee to 
assign such rights, and a copy of such agreement is furnished to the Company 
within a reasonable time after such assignment, (ii) the Company is, within a 
reasonable time after such transfer or assignment, furnished with written 
notice of (a) the name and address of such transferee or assignee, and (b) the 
securities with respect to which such registration rights are being 
transferred or assigned, (iii) following such transfer or assignment, the 
further disposition of such securities by the transferee or assignee is 
restricted under the 1933 Act and applicable state securities laws, (iv) at or 
before the time the Company receives the written notice contemplated by clause 
(ii) of this sentence, the transferee or assignee agrees in writing with the 
Company to be bound by all of the provisions contained herein, (v) such 
transfer shall have been made in accordance with the applicable requirements 
of the Securities Purchase Agreement, and (vi) such transferee shall be an 
"accredited investor" as that term defined in Rule 501 of Regulation D 
promulgated under the 1933 Act.

10.     AMENDMENT OF REGISTRATION RIGHTS.  

Provisions of this Agreement may be amended and the observance thereof may be 
waived (either generally or in a particular instance and either retroactively 
or prospectively), only with written consent of the Company, and Investors who 
hold a majority interest of the Registrable Securities.  Any amendment or 
waiver effected in accordance with this Section 10 shall be binding upon each 
Investor and the Company.

11.     MISCELLANEOUS.

a.     A person or entity is deemed to be a holder of Registrable Securities 
whenever such person or entity owns of record such Registrable Securities.  If 
the Company receives conflicting instructions, notices or elections from two 
or more persons or entities with respect to the same Registrable Securities, 
the Company shall act upon the basis of instructions, notice or election 
received from the registered owner of such Registrable Securities.

b.     Any notices required or permitted to be given under the terms hereof 
shall be sent by certified or registered mail (return receipt requested) or 
delivered personally or by courier (including a recognized overnight delivery 
service) or by facsimile and shall be effective five days after being placed 
in the mail, if mailed by regular U.S. mail, or upon receipt, if delivered 
personally or by courier (including a recognized overnight delivery service) 
or by facsimile, in each case addressed to a party.  The addresses for such

c.     Failure of any party to exercise any right or remedy under this 
Agreement or otherwise, or delay by a party in exercising such right or 
remedy, shall not operate as a waiver thereof.

           d.     This Agreement shall be enforced, governed by and construed 
in accordance with the laws of the State of Delaware applicable to agreements 
made and to be performed entirely within such State.  In the event that any 
provision of this Agreement is invalid or unenforceable under any applicable 
statute or rule of law, then such provision shall be deemed inoperative to the 
extent that it may conflict therewith and shall be deemed modified to conform 
with such statute or rule of law.  Any provision hereof which may prove 
invalid or unenforceable under any law shall not affect the validity or 
enforceability of any other provision hereof.  The parties hereto hereby 
submit to the exclusive jurisdiction of the United States Federal Courts 
located in Delaware with respect to any dispute arising under this Agreement 
or the transactions contemplated hereby.  

e.     This Agreement and the Securities Purchase Agreement (including all 
schedules and exhibits thereto) constitute the entire agreement among the 
parties hereto with respect to the subject matter hereof and thereof.  There 
are no restrictions, promises, warranties or undertakings, other than those 
set forth or referred to herein and therein.  This Agreement and the 
Securities Purchase Agreement supersede all prior agreements and 
understandings among the parties hereto with respect to the subject matter 
hereof and thereof.

f.     Subject to the requirements of Section 9 hereof, this Agreement shall 
inure to the benefit of and be binding upon the successors and assigns of each 
of the parties hereto.

g.     The headings in this Agreement are for convenience of reference only 
and shall not limit or otherwise affect the meaning hereof.

which shall be deemed an original but all of which shall constitute one and 
the same agreement.  This Agreement, once executed by a party, may be 
delivered to the other party hereto by facsimile transmission of a copy of 
this Agreement bearing the signature of the party so delivering this 
Agreement.

i.     Each party shall do and perform, or cause to be done and performed, all 
such further acts and things, and shall execute and deliver all such other 
agreements, certificates, instruments and documents, as the other party may 
reasonably request in order to carry out the intent and accomplish the 
purposes of this Agreement and the consummation of the transactions 
contemplated hereby.

j.     Except as otherwise provided herein, all consents and other 
determinations to be made by the Investors pursuant to this Agreement shall be 
made by Investors holding a majority of the Registrable Securities, determined 
as if the all of the shares of Preferred Stock then outstanding have been 
converted into for Registrable Securities.

k.     The language used in this Agreement will be deemed to be the language 
chosen by the parties to express their mutual intent, and no rules of strict 
construction will be applied against any party.
