undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, the Records deemed confidential.  The Company

Statement, (iii) the release of such information is ordered
pursuant to a subpoena or other order from a court or governmental

Stock pursuant to the Registration Statement.

Common Stock and shall execute such documents in connection with
such registration as the Company may reasonably request.  At least
fifteen (15) days prior to the first anticipated filing date of the

the information the Company requires from the Investor (the
"Requested Information").  For each day that the Requested
Information is not received beginning five business days from the
date of its request, the Company shall have the right to extend the
period for filing set forth Section 2(a) hereof by one day.

          (b)  The Investor agrees to cooperate with the Company as

preparation and filing of the Registration Statement hereunder.

          (c)  The Investor agrees that, upon receipt of any notice

described in Section 3(e) or 3(f), the Investor will immediately
discontinue disposition of Common Stock pursuant to the Registration

the prospectus covering such Common Stock current at the time of receipt
of such notice;

          (d)  In the event the Investor determines to engage the
services of an underwriter, the Investor agrees to 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 managing
underwriter of such offering and take such other actions as are
reasonably required in order to expedite or facilitate the
disposition of the Common Stock.

     5.   Expenses of Registration.  All expenses (other than
brokerage commissions or discounts) incurred in connection with
registrations, filings or qualifications pursuant to Section 2,
including, without limitation, all registration, listing and
qualifications fees, printers and accounting fees and the fees and
disbursements of counsel for the Company, shall be borne by the
Company; provided, however, that the Investor shall bear the fees
and out-of-pocket expenses of the one legal counsel selected by the
Investor pursuant to Section 3(g) hereof.

     6.   Indemnification.

          (a)  By the Company.  To the extent permitted by law, the
Company will indemnify and hold harmless the Investor, any
underwriter (as defined in the Securities Act) for the Investor,
the directors, if any, of such underwriter and the officers, if
any, of such underwriter, and each person, if any, who controls any
such underwriter within the meaning of the Securities Act or the
Exchange Act (each, an "Indemnified Person"), against any losses,
claims, damages, expenses or liabilities (joint or several)
(collectively "Claims") to which any of them become subject under
the Securities Act, the Exchange Act or otherwise, insofar as such
Claims (or actions or proceedings, whether commenced or threatened,
in respect thereof) arise out of or are based upon any of the
following statements, omissions or violations in the Registration
Statement, or any post-effective amendment thereof, or any
prospectus included therein:  (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration
Statement or any post-effective amendment thereof or the omission
or alleged omission to state therein a material fact required to be
stated therein 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 Securities Act, the Exchange Act or any state
securities law or any rule or regulation under the Securities Act,
the Exchange Act or any state securities law (the matters in the
foregoing clauses (i) through (iii) being, collectively,
"Violations").  Subject to the restrictions set forth in Section
6(d) with respect to the number of legal counsel, the Company shall
reimburse the Investor and each such underwriters or controlling
person, promptly as such expenses are incurred and are due and
payable, for any 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; (II) with respect
to any preliminary prospectus shall not inure to the benefit of any
such person from whom the person asserting any such Claim purchased
the Common Stock that are the subject thereof (or to the benefit of
any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary prospectus
was corrected in the prospectus, as then amended or supplemented;
(III) shall not be available to the extent such Claim is based on
a failure of the Investor to deliver or cause to be delivered the
prospectus made available by the Company; and (IV) 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.

          (b)  By the Investor.  In connection with any
Registration Statement in which an Investor is participating, the
Investor agrees to indemnify and hold harmless, 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 Securities Act or the Exchange Act (collectively and
together with an Indemnified Person, an "Indemnified Party"),
against any Claim to which any of them may become subject, under
the Securities Act, the Exchange Act or otherwise, insofar as such
Claim arises out of or is based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs (I)
in reliance upon and in conformity with written information
furnished to the Company by the Investor expressly for use in
connection with such Registration Statement or (II) the Investor's
violation of Regulation M; and the Investor will promptly reimburse
any legal or other expenses 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 the Investor, which consent shall not be unreasonably
withheld.  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 Common
Stock by the Investor.  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)  The Company shall be entitled to receive indemnities
from underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in any
distribution, to the same extent as provided above, with respect to
information such persons so furnished in writing by such persons
expressly for inclusion in the Registration Statement.  

          (d)  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 parties 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 written 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 or other party
represented by such counsel in such proceeding.  The Company shall
pay for only one separate legal counsel for the Investor.  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 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.  

          (e)  Contribution.  To the extent any indemnification
provided for herein 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
Common Stock guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled
to contribution from any seller of Common Stock who was not guilty
of such fraudulent misrepresentation and (iii) contribution by any
seller of Common Stock shall be limited in amount to the net amount
of proceeds received by such seller from the sale of such Common Stock.

     7.   Reports under Exchange Act.  With a view to making
available to the Investor the benefits of Rule 144 or any other
similar rule or regulation of the SEC that may at any time permit
the Investor to sell securities of the Company to the public
without Registration, until such time as the Investor has sold all
the Common Stock pursuant to a Registration Statement or 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 Securities Act 
and the Exchange Act; and

          (c)  furnish to the Investor so long as the Investor owns
Common Stock, promptly upon request, (i) a written statement by the
Company that it has complied with the reporting requirements of
Rule 144, the Securities Act and the Exchange Act, (ii) 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 (iii) such
other information as may be reasonably requested to permit the
Investor to sell such securities pursuant to Rule 144 without
Registration.  In addition, Investor shall continue to receive a
monthly report from the Company.

     8.   Assignment of the Registration Rights.  The rights to
have the Company register Common Stock pursuant to this Agreement
may not be assigned unless the Company agrees to the assignment in
writing. 

     9.   Amendment of Registration Rights.  Any provision 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 the written consent of
the Company and Investor.  Any amendment of waiver effected in
accordance with this Section 9 shall be binding upon the Investor
and the Company.  

     10.  Miscellaneous.

          (a)  If the Company receives conflicting instructions, 
notices or elections from two or more persons or entities with
respect to the same Common Stock, the company shall act upon the
basis of instructions, notice or election received from the
registered owner of such Common Stock.  

          (b)  Notices required or permitted to be given hereunder
shall be in writing and shall be deemed to be sufficiently given
when personally delivered or when sent by registered mail, return
receipt requested, addressed (i) if to the Company, at nStor

          (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 Florida
applicable to the agreements made and to be performed entirely
within such state, without giving effect to rules governing the
conflict of laws.  In the event that any provision of this

an indefinite period of time because the Shares have not been
registered under the Securities Act of 1933, as amended (the
"1933 Act"), or under any state securities laws and, therefore, cannot
be resold unless they are subsequently registered under the 1933 Act
and the pertinent state securities laws or unless an exemption
from such registration is available; (ii) the Investor is purchasing
the Shares for investment for his own account and not for the account
of any other person, and not with any present view toward resale
or other "distribution" thereof within the meaning of the 1933 Act;
and (iii) the Investor agrees not to resell or otherwise dispose
of all or any part of the Shares, except as permitted by law,
including, without limitation, any and all applicable provisions
of this Agreement and any regulations under the 1933 Act.

          (e)  The Investor has such knowledge and experience in
financial and business matters that he is capable of evaluating
the merits and risks of an investment in the Shares.  The Investor
represents, warrants and covenants that he is an "Accredited
Investor" within the meaning of Rule 501 of the 1933 Act.  In
particular, the Investor qualifies as such pursuant to
Subsections (a)(5) and (6) of Rule 501, which provides that an Accredited
Investor shall include:

          any natural person whose individual net worth,
          or joint net worth with that person's spouse,
          at the time of his purchase exceeds $1,000,000; and
          any natural person who had an individual
          income in excess of $200,000 in each of the
          two most recent years or joint income with
          that person's spouse in excess of $300,000 in
          each of those years and has a reasonable
          expectation of reaching the same income level
          in the current year."

          (f)  The Investor is aware that an investment in the
Shares is highly speculative and subject to substantial risks. 
The Investor is capable of bearing the high degree of economic risk
and burdens of this investment, including the possibility of a
complete loss of his investment and the lack of a public market and
limited transferability of the Shares, which may make the liquidation of
this investment impossible for an indefinite period of time.  The
financial condition of the Investor is such that he is under no
present or contemplated future need to dispose of any of the
Shares to satisfy any existing or contemplated undertaking, need or
indebtedness.

          (g)  All of the information that either Investor has
set forth or represented in this Agreement, with respect to his
financial position and business and investment experience is
correct and complete as of the date of this Agreement and, if
there should be any material change in such information prior to the
purchase of Shares, the Investor will immediately furnish the
revised or corrected information to the Company.

          (h)  The Investor is, as of the date hereof, the
beneficial owner of _____ shares of the Company's Common Stock.

          (i)  The Investor agrees that he shall be bound by all
of the terms, conditions, duties and obligations of this Agreement
insofar as such matters affect the Company and/or the Investor.

     13.  Restricted Stock and Legend.

          (a)  The Investor acknowledges that the Shares offered
hereunder are being offered pursuant to a private placement
exemption under the 1933 Act, and that the Shares are deemed
"restricted securities" as defined in the 1933 Act.  Until the
securities offered hereunder become registered with the
Securities and Exchange Commission, each certificate representing a share of
Common Stock shall bear a legend in substantially the following form:

          THE SHARE(S) REPRESENTED BY THIS CERTIFICATE HAVE
          NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED (THE "ACT"), OR UNDER ANY STATE
          SECURITIES LAWS, AND THE COMPANY HAS RELIED UPON AN
          EXEMPTION TO THE REGISTRATION REQUIREMENT UNDER THE
          ACT FOR THE SALE OF THE SHARE(S) REPRESENTED BY
          THIS CERTIFICATE TO ITS HOLDER.  THEREFORE, THE
          SHARES  REPRESENTED BY THIS CERTIFICATE ARE
          RESTRICTED STOCK AND MAY NOT BE SOLD OR TRANSFERRED
          TO ANY THIRD PARTY WITHOUT EITHER BEING REGISTERED
          UNDER THE ACT OR AN OPINION OF COUNSEL ACCEPTABLE
          TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED
          UNDER THE ACT.

          (b)  Prior to any transfer or attempted transfer of any
of the Shares issued hereunder, or any interest therein, the
Investor shall give the Company written notice of his intention
to make such transfer, describing the manner of the intended
transfer and the proposed transferee.  Promptly after receiving such
written notice, the Company shall present copies thereof to counsel for
the Company and to any special counsel designated by such Investor or
by such holder.  If in the opinion of each of such counsel the
proposed transfer may be effected without registration of the
Shares under the applicable federal or state securities laws, as
promptly as practicable, the Company shall notify the Investor of
such opinions, whereupon the Shares proposed to be transferred
shall be transferred in accordance with the terms of said notice. 
The Company shall not be required to effect any such transfer
prior to the receipt of such favorable opinion(s); provided, however,
the Company may waive the requirement that Investor obtain an opinion
of counsel, in its sole and absolute discretion.  As a condition
to such favorable opinion, counsel for the Company may require an
investment letter to be executed by the proposed transferee.

     14.  No Assignment.

          This Agreement is neither transferable nor assignable
by the Investor without the prior written consent of the Company.

     15.  General.

          (a)  This Agreement shall be binding upon the Investor
and the Company and their respective representatives, successors,
and permitted assigns; 

          (b)  This Agreement shall be governed, construed and
enforced in accordance with the internal laws of the State of
Florida;

          (c)  all covenants, agreements, representations and
warranties made herein or otherwise made in writing by any party
pursuant hereto shall survive the execution and delivery of this
Agreement and the consummation of the transactions contemplated
hereby;

          (d)  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same instrument; and

          (e)  Notices required or permitted to be given
hereunder shall be in writing and shall be deemed to be sufficiently given
when personally delivered or when sent by registered mail, return
receipt requested, addressed (i) if to the Company, at nStor
Technologies, Inc., 100 Century Blvd., West Palm Beach, FL 33417,
attn: Mark Levy, and (ii) if to the Investor, at the address set
forth under its name below, or at such other address as each such
party furnishes by notice given in accordance with this
Section 5(e), and shall be effective, when personally delivered,
upon receipt, and when so sent by certified mail, four business
days after deposit with the United States Postal Service.

Agreement as of the 14th day of April, 1999.

EXHIBIT 4.3


THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE THEREOF
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE "ACT"), AND MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED
OR OTHERWISE DISPOSED OF UNLESS REGISTERED PURSUANT TO THE ACT OR AN
OPINION OF LEGAL COUNSEL, REASONABLY SATISFACTORY TO THE COMPANY,
IS OBTAINED STATING THAT AN EXEMPTION FROM REGISTRATION UNDER THE
ACT IS AVAILABLE.  THIS WARRANT MAY NOT BE SOLD, TRANSFERRED OR
ASSIGNED EXCEPT UNDER THE LIMITED CIRCUMSTANCES DESCRIBED HEREIN.



DATED:  April 14, 1999                                     NO. __

                             WARRANT

                     nSTOR TECHNOLOGIES, INC.

                Warrant to Purchase 250,000 Shares
            of Common Stock, par value $.05 per share 

           VOID AFTER 5:00 P.M., EASTERN STANDARD TIME
                        ON APRIL 13, 2002

The Company (as hereafter defined) has previously issued to
Holder (as hereafter defined) 500,000 shares of the Company's common
stock, par value $.05 per share (the "Common Stock").  As
additional consideration for the Holder's purchase of the Common
Stock, the Company desires to issue this Warrant (as hereafter
defined) in accordance with the terms and conditions set forth
herein.

This certifies that, for value received, Bernard Marden
("Marden"), or registered assigns (collectively with Marden, the "Holder"),
is entitled to purchase from nStor Technologies, Inc., a Delaware
corporation (the "Company"), Two Hundred Fifty Thousand (250,000)
fully paid and nonassessable shares (the "Shares") of the Common
Stock of the Company at a price of $2.00 per Share (the "Exercise
Price") at any time from and after April 14, 1999 to and
including 5:00 p.m. Eastern Standard Time on April 14, 2002 (the "Exercise
Period"), subject to the terms, conditions and adjustments set
forth in this Warrant (the "Warrant").

1.   Exercise of Warrants.  This Warrant may be exercised in
whole or in part by the Holder during the Exercise Period upon
presentation and surrender hereof, with the attached Purchase
Form duly executed, at the office of the Company located at 100
Century Boulevard, West Palm Beach, FL  33417, accompanied by full
payment of the Exercise Price multiplied by the number of Shares of the
Company being purchased (the "Purchase Price"), whereupon the
Company shall cause the appropriate number of Shares to be issued
and shall deliver to the Holder, as promptly as practicable, a
certificate representing the Shares being purchased.  This
Warrant may be exercised for not less than 1,000 Shares and in additional
increments of 1,000 Shares at any time and from time to time
during the Exercise Period.  Upon each partial exercise hereof, a new
Warrant evidencing the remainder of the Shares will be issued to
the Holder, at the Company's expense, as soon as reasonably
practicable, at the same Exercise Price, for the same Exercise
Period, and otherwise of like tenor as the Warrant partially
exercised.  The Purchase Price shall be payable by delivery of a
certified or bank cashier's check payable to the Company, or by
wire transfer of immediately available funds to an account
designated in writing by the Company, in the amount of the
Purchase Price.  The Holder shall be deemed for all purposes to have
become the holder of record of Shares so purchased upon exercise of this
Warrant as of the close of business on the date as of which this
Warrant, together with a duly executed Purchase Form, was
delivered to the Company and payment of the Purchase Price was made,
regardless of the date of delivery of any certificate
representing the Shares so purchased, except that if the Company were subject
to any legal requirements prohibiting it from issuing shares of
Common Stock on such date, the Holder shall be deemed to have become the
record holder of such Shares on the next succeeding date as of
which the Company ceased to be so prohibited.  

2.   Exchange; Restrictions on Transfer or Assignment.  This
Warrant is exchangeable, without expense, at the option of the
Holder, upon surrender hereof to the Company for other Warrants
of like tenor of different denominations entitling the Holder to
purchase in the aggregate the same number of Shares purchasable
hereunder.  This Warrant and the Holder's rights hereunder may
not be transferred, assigned or subjected to a pledge or security
interest, except that the Holder may transfer this Warrant in
whole or in part (in minimum increments of 1,000 Shares) to a
corporation controlled by or under common control with the Holder, by
surrender of this Warrant to the Company at its principal office with the
assignment form attached hereto duly completed and executed (with
signature guaranteed), whereupon the Company, if it determines
that the proposed assignment is permitted pursuant to the provisions
hereof, shall register the assignment of this Warrant in
accordance with the information contained in the assignment instrument and
shall, without charge, execute and deliver a new Warrant or
Warrants in the name of the assignee or assignees named in such
assignment instrument (and, if applicable, a new Warrant in the
name of the Holder evidencing any remaining portion of the
Warrant not theretofore exercised, transferred or assigned) and this
Warrant shall promptly be cancelled.  Conditions to the transfer
of this Warrant or any portion thereof shall be that the proposed
transferee deliver to the Company his or its written agreement to
accept and be bound by all of the terms and conditions of this
Warrant.  The term "Warrant" as used herein includes any Warrants
into which this Warrant may be divided or exchanged.

3.   Rights and Obligations of Warrant Holders.  This Warrant
does not confer upon the Holder any rights as a shareholder of the
Company, either at law or in equity.  The rights of the Holder
are limited to those expressed herein and the Holder, by acceptance
hereof, consents to and agrees to be bound by and to comply with
all the provisions of this Warrant.  Each Holder, by acceptance
of this Warrant, agrees that the Company and its transfer agent, if
any, may, prior to any presentation of this Warrant for
registration of transfer, deem and treat the person in whose name
this Warrant is registered as the absolute, true and lawful owner
of this Warrant for all purposes whatsoever and neither the
Company nor any transfer agent shall be affected by any notice to the
contrary.

4.   Covenants and Warranties of the Company.  The Company
covenants and agrees that (i) all Shares which may be issued and
delivered upon exercise of this Warrant and payment of the
Purchase Price will, upon delivery, be duly authorized, validly issued,
fully-paid and nonassessable shares of Common Stock; and (ii) the
Company shall at all times during the Exercise Period reserve and
keep available a number of authorized but unissued shares of
Common Stock sufficient to permit the exercise in full of this Warrant. 
The Company will take all such actions as may be necessary to
assure that all shares of Common Stock may be so issued without
violation by the Company of any applicable law or government
regulation or any requirement of any securities exchange upon
which shares of Common Stock may be listed (except for official notice
of issuance, which the Company will transmit promptly upon issuance
of such shares).  The Company will at no time close its shareholder
books or records in any manner which interferes with the timely
exercise of this Warrant.

The Company represents and warrants that:  (i) the Company is a
corporation duly organized, validly existing and in good standing
under the laws of the state of Delaware; (ii) the Company has all
requisite corporate power and authority to issue this Warrant and
to consummate the transactions contemplated hereby, and such
issuance and consummation will not conflict with, result in a
material breach of, constitute a material default under or
material violation of any provision of the Company's Articles of
Incorporation or Bylaws, and to the best knowledge of the
Company, any law or regulation of any governmental authority or any
provision of any agreement, judgment or decree affecting the
Company; and (iii) all corporate action required to be taken by
the Company in connection with the execution and delivery of this
Warrant and the performance of the Company's obligations
hereunder has been taken. 

5.   Disposition of Warrants or Shares.  The Holder acknowledges
that this Warrant and the Shares issuable upon exercise thereof
have not been registered under the Act or applicable state law.
The Holder agrees, by acceptance of this Warrant, (i) that no sale,
transfer or distribution of this Warrant or the Shares shall be
made except in compliance with the Act and the rules and
regulations promulgated thereunder, including any applicable
prospectus delivery requirements and the restrictions on transfer
set forth herein, and (ii) that if distribution of this Warrant
or any Shares is proposed to be made by it otherwise than by
delivery of a prospectus meeting the requirements of Section 10 of the
Act, such action shall be taken only after submission to the Company
of an opinion of counsel, reasonably satisfactory in form and
substance to the Company's counsel, to the effect that the
proposed distribution will not be in violation of the Act or of applicable
state law.

6.   Adjustment.  The number of Shares purchasable upon the
exercise of this Warrant and the Exercise Price per Share are
subject to adjustment from time to time as provided in this Section 6.

  (a)  Subdivision or Combination of Shares.  If the Company
shall at any time subdivide its outstanding shares of Common Stock into
a greater number of shares (including a stock split effected as a
stock dividend) or combine its outstanding shares of Common Stock
into a lesser number of shares, the number of Shares issuable
upon exercise of this Warrant shall be adjusted to such number as is
obtained by multiplying the number of shares issuable upon
exercise of this Warrant immediately prior to such subdivision or
combination by a fraction, the numerator of which is the
aggregate number of shares of Common Stock outstanding immediately after
giving effect to such subdivision or combination and the
denominator of which is the aggregate number of shares of Common
Stock outstanding immediately prior to such subdivision or
combination, and the Exercise Price per Share shall be
correspondingly adjusted to such amount as shall, when multiplied
by the number of Shares issuable upon full exercise of this
Warrant (as increased or decreased to reflect such subdivision or
combination of outstanding shares of Common Stock, as the case
may be), equal the product of the Exercise Price per Share in effect
immediately prior to such subdivision or combination multiplied
by the number of Shares issuable upon exercise of this Warrant
immediately prior to such subdivision or combination.

  (b)  Effect of Sale, Merger or Consolidation.  If any capital
reorganization or reclassification of the capital stock of the
Company, or consolidation or merger of the Company with another
corporation, or sale of all or substantially all of the Company's
assets to another corporation shall be effected after the date
hereof in such a way that holders of Common Stock shall be
entitled to receive stock, securities or assets with respect to or in
exchange for Common Stock, then, as a condition of such
reorganization, reclassification, consolidation, merger or sale,
lawful and adequate provision shall be made whereby the Holder
shall thereafter have the right to purchase and receive, upon the
basis and the terms and conditions specified in this Warrant and
in lieu of the Shares immediately theretofore purchasable and
receivable upon the exercise of this Warrant, such shares of
stock, securities or assets as may be issued or payable with respect to
or in exchange for a number of outstanding shares of Common Stock
equal to the number of shares of Common Stock immediately
theretofore purchasable and receivable upon the exercise of this
Warrant, and in any such case appropriate provision shall be made
with respect to the rights and interests of the Holder to the end
that the provisions of this Warrant (including, without
limitation, provisions for adjustments of the Exercise Price and of the
number of Shares issuable upon the exercise of this Warrant) shall
thereafter be applicable, as nearly as may be possible, in
relation to any shares of stock, securities or assets thereafter
deliverable upon the exercise of this Warrant.  The Company shall not effect
any such consolidation, merger or sale unless prior to or
simultaneously with the consummation thereof the successor
corporation (if other than the Company) resulting from such
consolidation or merger or the corporation purchasing such assets
shall assume, by written instrument executed and delivered to the
Holder at its last address appearing on the books of the Company,
the obligation to deliver to the Holder such shares of stock,
securities or assets as, in accordance with the foregoing
sentence, the Holder may be entitled to purchase.

  (c)  Notice to Holder of Adjustment.  Whenever the number of
Shares purchasable upon exercise of this Warrant or the Exercise
Price per Share is adjusted as herein provided, the Company shall
cause to be mailed to the Holder, in accordance with the
provisions of Section 10 hereof, notice setting forth the adjusted number of
Shares purchasable upon the exercise of the Warrant and the
adjusted Exercise Price and showing in reasonable detail the
computation of the adjustment and the facts upon which such
adjustment is based.

  (d)  Notices to Holder of Certain Events.  If at any time after
the date hereof:

       (i)  the Company shall declare any dividend or other
  distribution upon or with respect to the Common Stock payable
  otherwise than in cash out of the consolidated net income of the
  Company and any subsidiaries thereof, including any dividend
  payable in shares of Common Stock or other securities of the
  Company; or

       (ii)  the Company shall offer for subscription to the
  holders of its Common Stock any additional shares of stock of
  any class or any other securities convertible into stock or any
  rights to subscribe thereto; or

       (iii)  there shall be any capital reorganization or
  reclassification of the capital stock of the Company (other
  than   a change in par value, or from par value to no par value, or
  from no par value to par value or as result of the subdivision
  or combination of shares), or any conversion of the Shares into
  securities of another corporation, or a sale of all or
  substantially all of the assets of the Company, or a
  consolidation or merger of the Company with another corporation
  (other than a merger with a subsidiary in which the Company is
  the continuing corporation and which does not result in any
  reclassification or change of the Shares issuable upon exercise
  of the Warrants); or

       (iv)  there shall be a voluntary or involuntary
  dissolution, liquidation or winding up of the Company;

then, in any one or more of said cases, the Company shall cause
to be mailed to the Holder, not less than ten (10) days before any
record date or other date set for the definitive action, written
notice of the date upon which the books of the Company shall
close or a record shall be taken for purposes of such dividend,
distribution or subscription rights or upon which such
reorganization, reclassification, conversion, sale,
consolidation, merger, dissolution, liquidation or winding up shall take place,
as the case may be.  Such notice shall also set forth facts as shall
indicate the effect of such action (to the extent such effect may
be known at the date of such notice) on the number of Shares and
the kind and amount of the shares of stock and other securities
and property deliverable upon exercise of the Warrants.  Such notice
shall also specify the date as of which the holder of record of
the shares of Common Stock shall participate in said dividend,
distribution or subscription rights or shall be entitled to
exchange their shares of Common Stock for securities or other
property deliverable upon such reorganization, reclassification,
conversion, sale, consolidation, merger, dissolution, liquidation
or winding up, as the case may be (on which date in the event of
voluntary or involuntary dissolution, liquidation or winding up
of the Company, the right to exercise the Warrants shall terminate).

  (e)  Fractional Shares.  The Company shall not be required to
issue any fraction of a Share upon the exercise of this Warrant. 
The number of full Shares which shall be issuable upon the full
or partial exercise of this Warrant shall be computed on the basis
of the aggregate number of Shares as to which this Warrant is being
exercised.  In lieu of any fractional interest in a Share
otherwise deliverable upon the exercise of this Warrant, the Company shall
pay a cash adjustment (which may be effected as a reduction of
the amount to be paid by the Holder upon such exercise) in respect of
such fraction of a Share in an amount equal to the same fraction
multiplied by the closing sales price of the Common Stock on the
principal securities exchange on which the Common Stock is
traded, or if the Common Stock is not so listed for trading, the closing
bid price of the Common Stock, in each case on the date of the
notice of exercise required pursuant to Section 1 above, or the
next succeeding trading date, if the date of such notice is not a
trading date, or if the Common Stock is not traded on such dates,
the next succeeding trading date on which the Common Stock is
traded.

  (f)  No Other Adjustments.  No adjustment to the number of
Shares subject to this Warrant or the Exercise Price per Share shall be
made pursuant to this Section 6 except as expressly provided
herein.

7.   Piggy-Back Registration. 

  (a)  In the event the Company shall, at any time prior to the
expiration of this Warrant, file a registration statement with
the Securities and Exchange Commission (the "SEC") to register shares
of Common Stock, the Company shall furnish the Holders with at
least thirty (30) days prior written notice thereof and such
Holders shall have the option to include the Shares to be issued
to the Holders upon the exercise of this Warrant in such
registration statement.  The Holders shall exercise the "piggy-back
registration rights" granted pursuant to this Section 7 by giving written
notice to the Company within twenty (20) days of the receipt of the
aforementioned written notice from the Company.  

  (b)  Notwithstanding any other provision of this Warrant, the
Company's obligations under this Section 7 shall be subject to
and limited by the following terms and conditions:

     (i) The obligations of the Company set forth under this
Section 7 shall not arise upon the filing of a registration
statement relating solely to shares of Common Stock issued
pursuant to  employee stock option or other benefit plans, a merger of
other business combination or a registration statement which does not
include substantially the same information as Form S-1, Form S-2
or Form S-3, or any successor forms thereto.

     (ii)  If the Company files a registration statement in
connection with a proposed underwritten primary or secondary
public offering of Common Stock, the Company shall use its best efforts
to cause the managing underwriter of the proposed offering to grant
any request by the Holder that Shares purchased by the Holder
upon the exercise of this Warrant be included in the proposed public
offering on terms and conditions which are customary under
industry practice. Notwithstanding any other provision of this Agreement,
if the managing underwriter of a proposed primary or secondary
public offering of the Common Stock gives written notice to the Company
that, in the reasonable opinion of such managing underwriter,
marketing factors require a limitation of the total number of
shares of Common Stock to be underwritten, then the number of
Shares purchased by the Holder upon the exercise of this Warrant
which the Company shall be obligated to include in the
registration statement shall be reduced in accordance with the limitations
imposed by the managing underwriter.  Any such limitation imposed
by the managing underwriter shall be imposed pro rata among all
holders of Common Stock exercising rights granted pursuant to
this Section 7 or otherwise, in accordance with the amount of Common
Stock which each such person requested to be included in the
registration statement.

  (c)  The Company will pay all Registration Expenses (as
hereinafter defined) of all registrations under this Warrant;
provided, however, that if a registration is withdrawn at the
request of the Holders requesting such registration (other than
as a result of information concerning the business or financial
condition of the Company which is made known to the Holders after
the date on which such registration was requested), each of the
Holders shall pay the Registration Expenses of such registration
pro rata in accordance with the number of its Shares included in
such registration.  For purposes of this Section 7, the term
"Registration Expenses" shall mean all expenses incurred by the
Company in complying with this Section 7, including, without
limitation, all registration and filing fees, exchange listing
fees, printing expenses, fees and disbursements of counsel for
the Company, state Blue Sky fees and expenses, transfer agent fees,
cost of engraving of stock certificates, costs for mailing and
tombstone advertising, cost of preparing the registration
statement, related exhibits, amendments and supplements thereto,
underwriting documents, selected dealer agreements, preliminary
and final prospectuses, and the expense of any special audits
incident to or required by any such registration, but excluding
underwriting discounts and selling commissions attributable to the Shares and
the fees and expenses of the Holder's own counsel and
accountants, which shall be borne by such holders.

8.   Indemnification and Notification.

  (1)  The Company will indemnify and hold harmless the Holders,
and each person, if any, who controls such Holders within the
meaning of Section 15 of the Act, from and against any and all
losses, claims, damages, expenses and liabilities caused by any
untrue statement of a material fact contained in any registration
statement or contained in a prospectus furnished thereunder or
caused by any omission to state a material fact therein necessary
to make the statement therein not misleading provided, however,
that the foregoing indemnification and agreement to hold harmless
shall not apply insofar as such losses, claims, damages, expenses
and liabilities are caused by any such untrue statement or
omissions based upon information furnished in writing to the
Company by any such Holder expressly for use in any registration
statement or prospectus.

  (2)  The Holders will indemnify the Company, and each person
who controls the Company within the meaning of Section 15 of the Act,
from and against any and all losses, claims, damages, expenses
and liabilities caused by an untrue statement of a material fact
contained in any registration statement or contained in a
prospectus furnished thereunder or caused by an omission to state
a material fact therein necessary to make the statement therein
not misleading insofar as such losses, claims, damages, expenses and
liabilities caused by such untrue statement or omission based
upon information furnished in writing to the Company by any such
Holder expressly for use in any registration statement or prospectus.

  (3)  Promptly after the receipt by any indemnified party of
notice of the commencement of any action, said indemnified party
will, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the indemnifying
party in writing of the commencement thereof; but the omission to
so notify the indemnifying party will not relieve it from any
liabilities which it may have to them otherwise than under this
Section 8, except if such delay prejudices the indemnifying
party. In case any such action is brought against any party who may seek
indemnification hereunder and the indemnifying party is notified
of the commencement thereof as provided herein, the indemnifying
party will be entitled to participate in, and, to the extent that it
may wish, to assume the defense thereof, with counsel satisfactory to
the indemnified party, and after notice from the indemnifying
