         THIS REGISTRATION RIGHTS AGREEMENT, dated as of October 31, 1996 (this

Investor").

                              W I T N E S S E T H:

         WHEREAS, in connection with the Subscription Agreement, dated as of
October 31, 1996, between the Initial Investor and the Company (the
"Subscription Agreement"), the Company has agreed, upon the terms and subject to
the conditions of the Subscription Agreement, to issue and sell to the Initial
Investor an aggregate of 12,500 shares (the "Preferred Shares") of preferred
stock of the Company as provided in the Subscription Agreement, which shares of
Preferred Stock are convertible into units consisting of (x) shares (the
"Conversion Shares") of Common Stock, $.001 par value (the "Common Stock"), of
the Company and (2) warrants (the "Warrants") to purchase shares of Common Stock
(the "Warrant Shares"); and

         WHEREAS, to induce the Initial Investor to execute and deliver the
Subscription 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
"Securities Act"), and applicable state securities laws with respect to the
Conversion Shares and the Warrant Shares;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and the
Initial Investor hereby agree as follows:

         1. DEFINITIONS.

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

         (i) "Investor" means the Initial Investor and any transferee or
assignee who agrees to become bound

                                      -1-
   2
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 Securities Act and pursuant to Rule 415 under
the Securities 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, the Warrant
Shares and any shares of Common Stock issued by the Company to any Investor as a
dividend on the Preferred Shares.

         (iv) "Registration Statement" means a registration statement of the
Company under the Securities Act, including any amendment thereto.

         (b) As used in this Agreement, the term Investor includes (i) each
Investor (as defined above) and (ii) each person who is a permitted transferee
or assignee of the Registrable Securities pursuant to Section 9 of this
Agreement.

         (c) Capitalized terms defined in the introductory paragraph or the
recitals to this Agreement shall have the respective meanings therein provided.
Capitalized terms used herein and not otherwise defined herein shall have the
respective meanings set forth in the Subscription Agreement.

         2.       REGISTRATION.

         (a) MANDATORY REGISTRATION. The Company shall prepare, and on or prior
to the date which is 30 days after the date of the closing under the
Subscription Agreement (the "Closing Date"), file with the SEC a Registration
Statement on Form S-1 covering at least 8,333,000 shares of Common Stock as
Registrable Securities, and which Registration Statement shall state that, in
accordance with Rule 416 under the Securities Act, such Registration Statement
also covers such indeterminate number of additional shares of Common Stock as
may become issuable upon conversion of the Preferred Shares to prevent dilution
resulting from stock splits, stock dividends or similar transactions or by
reason of changes in the conversion price of the Preferred Shares in accordance
with the terms


                                      -2-
   3
thereof. If at any time the number of shares of Common Stock included in the
Registration Statement required to be filed as provided in the first sentence of
this Section 2(a) shall be insufficient to cover the number of shares of Common
Stock issuable on conversion in full of the unconverted Preferred Shares and
exercise in full of the unexercised Warrants and Warrants which may be issued
upon exercise of the unconverted Preferred Stock, then promptly, but in no event
later than 20 days after such insufficiency shall occur, the Company shall file
with the SEC an additional Registration Statement on Form S-3, if available, or
Form S-1 or other applicable form (which shall not constitute a post-effective
amendment to the Registration Statement filed pursuant to the first sentence of
this Section 2(a)) covering such number of shares of Common Stock as shall be
sufficient to permit such conversion. For all purposes of this Agreement (other
than Section 2(c) hereof) such additional Registration Statement shall be deemed
to be the Registration Statement required to be filed by the Company pursuant to
Section 2(a) of this Agreement, and the Company and the Investors shall have the
same rights and obligations (other than Section 2(c) hereof) with respect to
such additional Registration Statement as they shall have with respect to the
initial Registration Statement required to be filed by the Company pursuant to
this Section 2(a).

         (b) CERTAIN OFFERINGS. If any offering pursuant to a Registration
Statement pursuant to Section 2(a) hereof involves an underwritten offering, the
Company shall have the right to select one legal counsel and an investment
banker or bankers and manager or managers to administer the offering, which
investment banker or bankers or manager or managers shall be reasonably
satisfactory to the Investors who hold a majority in interest of the Registrable
Securities subject to such underwritten offering. The Investors who hold the
Registrable Securities to be included in such underwriting shall pay all
underwriting discounts and commissions and other fees and expenses of such
investment banker or bankers and manager or managers so selected in accordance
with this Section 2(b) (other than fees and expenses relating to registration of
Registrable Securities under federal or state securities laws, which are payable
by the Company pursuant to Section 5 hereof) with respect to their Registrable
Securities and the fees and expenses of such legal counsel so selected by the
Investors.

                  (c) PAYMENTS BY THE COMPANY. If (1) the Registration Statement
covering the Registrable Securities which is required to be filed by the Company
pursuant to


                                      -3-
   4
the first sentence of Section 2(a) hereof is not effective within 80 days after
the Closing Date, (2) the Registration Statement required to be filed by the
Company pursuant to Section 2(a) shall cease to be available for use by any
holder of shares of Series B Convertible Preferred Stock which is named therein
as a selling stockholder for any reason (including, without limitation, by
reason of an SEC stop order, a material misstatement or omission in such
Registration Statement or the information contained in such Registration
Statement having become outdated (other than the Registration Statement having
become outdated in connection with the Company's exercise of its rights pursuant
to Section 3(f)(ii) hereof)) or (3) a holder of shares of Series B Convertible
Preferred Stock having become unable to convert any shares of Series B
Convertible Preferred Stock in accordance with Section 9(a) of the Certificate
of Designations (other than by reason of the 4.9% limitation set forth therein),
then, in lieu of the adjustment of the Conversion Percentage (as defined in the
Certificate of Designations on any particular Computation Date) the Company
shall have the right to make payment to the Initial Investor in such amount and
at such time as shall be determined pursuant to this Section 2(c). The amount to
be paid by the Company to the Initial Investor shall be determined as of each
Computation Date, and such amount shall be equal to two-and-one-half percent
(2.5%) of the aggregate subscription price paid by the Initial Investor for the
Preferred Shares pursuant to the Subscription Agreement (each, a "Periodic
Amount"); provided, however, that the maximum aggregate amount payable by the
Company pursuant to this Section 2(c) shall be an amount equal to fifteen
percent (15%) of the aggregate subscription price paid by the Initial Investor
pursuant to the Subscription Agreement. If the Company elects to make payment
hereunder of any Periodic Amount, such payment shall be made by the Company by
wire transfer in immediately available funds on the applicable Computation Date
to such account as shall be specified for such purpose by the Initial Holder.

                  As used in this Section 2(c), "Computation Date" shall have
the meaning provided in the Certificate of Designations.

         (d) PIGGY-BACK REGISTRATIONS. If at any time the Company shall
determine to prepare and file with the SEC a Registration Statement relating to
an offering for its own account or the account of others under the Securities
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


                                      -4-
   5
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(d) written notice of such determination and, if within ten (10) days after
receipt 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, such limitation is necessary to
effect an orderly 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. 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 by right to inclusion of securities in such
Registration Statement; 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, based on the number of
securities for which registration is requested except to the extent such pro
rata exclusion of such other securities is prohibited under any written
agreement entered into by the Company with the holder of such other securities
prior to the date of this Agreement, in which case such other securities shall
be excluded, if at all, in accordance with the terms of such agreement. No right
to registration of Registrable Securities under this Section 2(d) shall be
construed to limit any registration required under Section 2(a) hereof. The
obligations of the Company under this Section 2(d) may be waived by Investors
holding a majority in interest of the Registrable Securities and shall expire
after the Company has afforded the opportunity for the Investors to exercise
registration rights under this Section 2(d) for two registrations; provided,
however, that any Investor who shall have had any Registrable Securities
excluded from any Registration Statement in accordance with this Section 2(d)
shall be entitled to include in an additional Registration Statement filed by
the Company the Registrable Securities


                                      -5-
   6
so excluded. Notwithstanding any other provision of this Agreement, if the
Registration Statement required to be filed pursuant to Section 2(a) of this
Agreement shall have been ordered effective by the SEC and the Company shall
have maintained the effectiveness of such Registration Statement as required by
this Agreement and if the Company shall otherwise have complied in all material
respects with its obligations under this Agreement, then the Company shall not
be obligated to register any Registrable Securities on such Registration
Statement referred to in this Section 2(d).

                  (e) ELIGIBILITY FOR FORM S-3. The Company shall file all
reports required to be filed by the Company with the SEC in a timely manner so
as to become eligible for the use of Form S-3 and 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:

         (a) prepare promptly, and file with the SEC not later than 30 days
after the Closing Date, a Registration Statement with respect to the number of
Registrable Securities provided in Section 2(a), and thereafter to use its best
efforts to cause each Registration Statement relating to Registrable Securities
to become effective as soon as possible after such filing, and keep the
Registration Statement effective pursuant to Rule 415 at all times until the
earlier of (1) such date as is three years after the Closing Date and (2) the
date on which the Investors no longer beneficially own any Registrable
Securities, which Registration Statement (including any amendments or
supplements thereto and prospectuses contained therein) shall not contain any
untrue statement of a material fact or omit to state 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; provided, however, that
if the Company is seeking to accomplish a Significant Business Development (as
defined in Section 3(f)) and notifies the Investors in writing of such intent
and otherwise complies with the provisions of Section 3(f) hereof prior to the
time that the Registration Statement has been declared effective, the Company
shall have the right, for a period of up to thirty (30) days, to delay seeking
effectiveness of the Registration Statement provided that such period of up to
thirty (30) days ends on or before the 80th day following the Closing Date or
such later date as agreed to by the Investors.

                                      -6-

         (b) subject to the provisions of paragraph (f)(ii) below, 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 until such date as is three years after the
Closing Date, and, during such period, comply with the provisions of the
Securities 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;

         (c) furnish to each Investor whose Registrable Securities are included
in the Registration Statement and its legal counsel, (1) 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,
each letter written by or on behalf of the Company to the SEC or the staff of
the SEC and each item of correspondence from the SEC or the staff of the SEC
relating to such Registration Statement (other than any portion of any thereof
which contains information for which the Company has sought confidential
treatment) and (2) 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;

         (d) use reasonable efforts to (i) register and qualify the Registrable
Securities covered by the Registration Statement under such securities or blue
sky laws of such jurisdictions 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 at all times until the earlier
of (A) such date as is three years after the Closing Date and (B) the date on
which the Investors no longer beneficially own any Registrable Securities, (iii)
take such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times until the earlier of (A) such date as is
three years after the date such


                                      -7-
   8
Registration Statement is first ordered effective by the SEC and (B) the date on
which the Investors no longer beneficially own any Registrable Securities 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 (I) to qualify to do business in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(d), (II) to subject
itself to general taxation in any such jurisdiction, (III) to file a general
consent to service of process in any such jurisdiction, (IV) to provide any
undertakings that cause more than nominal expense or burden to the Company or
(V) to make any change in its charter or by-laws, which in each case the Board
of Directors of the Company determines to be contrary to the best interests of
the Company and its stockholders;

         (e) in the event that the Registrable Securities are being offered in
an underwritten offering, 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) (i) as promptly as practicable after becoming aware of such event,
notify each Investor of 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
omits to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, 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 a number of copies of such supplement or amendment to each
Investor as such Investor may reasonably request;

         (ii) Notwithstanding Section 3(f)(i), if at the time the Company
notifies the Investors as contemplated by Section 3(f)(i) that such event
relates to a prospective development which constitutes a Significant Business
Development (as defined herein) of the Company, then the Company shall not be
required to make such amendment or supplement for a period of up to thirty (30)
days commencing on the date the prospectus included in the Registration
Statement becomes unavailable for use due to such Significant Business
Development; provided, however, that the Company may not invoke the provisions
of this


                                      -8-
   9
Section 3(f)(ii) for more than thirty (30) days during any 180 day period;

                  (iii) A "Significant Business Development" shall mean (a) any
business combination transaction involving the purchase of the Company at a
premium to the market price of the Common Stock or a purchase of all or
substantially all of the assets of the Company at a price which, if the
consideration therefor were distributed to the stockholders of the Company,
would constitute a premium to the market price of the Common Stock at the time
such transaction is first publicly announced by the Company, (b) any business
combination transaction involving the acquisition by the Company of another
business for aggregate consideration in an amount in excess of $50 million, or
(c) any financing transaction involving the raising by the Company of funds in
an amount in excess of $10 million;

         (g) as promptly as practicable after becoming aware of such event,
notify each Investor who holds Registrable Securities being sold (or, in the
event of an underwritten offering, the managing underwriters) of the issuance by
the SEC of any stop order or other suspension of effectiveness of the
Registration Statement at the earliest possible time;

         (h) permit a single firm of counsel designated as selling stockholders'
counsel by the Investors who hold a majority in interest of the Registrable
Securities being sold to review and comment on the Registration Statement and
all amendments and supplements thereto a reasonable period of time prior to
their filing with the SEC;

         (i) 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 Securities 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 Company's Registration Statement on Form S-4 which was
declared effective by the SEC on July 12, 1996;

         (j) at the request of the Investors who hold a majority in interest of
the Registrable Securities being sold, furnish on the date that Registrable
Securities are delivered to an underwriter, if any, for sale in connection with
the Registration Statement (i) a letter, dated such date, from the Company's
independent certified public accountants in form and substance as is customarily
given

                                      -9-
   10
by independent certified public accountants to underwriters in an underwritten
public offering, addressed to the underwriters; and (ii) an opinion, dated such
date, from counsel representing the Company for purposes of such Registration
Statement, in form and substance as is customarily given in an underwritten
public offering, addressed to the underwriters and the Investors;

         (k) make available for inspection by any Investor, any underwriter
participating in any disposition pursuant to the Registration Statement, and any
attorney, accountant or other agent retained by any such Investor or underwriter
(collectively, the "Inspectors"), all pertinent financial and other records,
pertinent corporate documents and properties of the Company (collectively, the
"Records"), as shall be reasonably necessary 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 (i) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in any Registration
Statement, (ii) the release of such Records is ordered pursuant to a subpoena or
other order from a court or government body of competent jurisdiction or (iii)
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. The Company shall hold in confidence and shall not make any
disclosure of information concerning an Investor provided to the Company
pursuant to Section 4(e) hereof 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

                                      -10-
   11
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, at its expense, to undertake appropriate
action to prevent disclosure of, or to obtain a protective order for, such
information;

         (l) use its best efforts (i) to cause all the Registrable Securities
covered by the Registration Statement to be listed on the American Stock
Exchange, Inc. ("AMEX") or such other principal securities market on which
securities of the same class or series issued by the Company are then listed or
traded or (ii) if securities of the same class or series as the Registrable
Securities are not then listed on AMEX or any such other securities market, to
cause all of the Registrable Securities covered by the Registration Statement to
be listed on the Nasdaq National Market or the New York Stock Exchange;

         (m) 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;

         (n) 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 three 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 substantially in the form attached hereto as EXHIBIT 1 and an
opinion of such


                                      -11-
   12
counsel, if required by the Company's transfer agent, in the form attached
hereto as EXHIBIT 2; and

         (o) take all other reasonable actions necessary to expedite and
facilitate disposition by the Investor of the 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 four (4) 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 (the "Requested Information") if any of such Investor's
Registrable Securities are eligible for inclusion in the Registration Statement.
If at least one (1) business day prior to the filing date the Company has not
received the Requested Information from an Investor (a "Non-Responsive
Investor"), then the Company may file the Registration Statement without
including Registrable Securities of such Non-Responsive 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 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


                                      -12-
   13
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; and

         (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 approved by
the Investors entitled hereunder to approve such arrangements, (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 other fees and expenses of investment
bankers and any manager or managers of such underwriting and legal expenses of
the underwriters applicable with respect to its Registrable Securities, in each
case to the extent not payable by the Company pursuant to the terms of this
Agreement.

         5. EXPENSES OF REGISTRATION. All reasonable expenses, other than
underwriting discounts and commissions and other fees and expenses of investment
bankers and other than brokerage commissions, incurred in connection with
registrations, filings or qualifications pursuant to Section 3 and other than
the legal fees for the Investors, 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.

         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 and hold
harmless each Investor who holds such Registrable Securities, the directors, if
any, of such Investor, the officers, if any, of such Investor, each person, if
any, who controls any Investor within the meaning of the Securities Act or the
Exchange Act, any underwriter (as defined in the Securities Act) for the
Investors, 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, liabilities or
expenses (joint or several) incurred (collectively, "Claims") to which any of
them may 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, 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 Investors and each such
underwriter or controlling person, promptly as such expenses are incurred and
are due and payable, for


                                      -14-
   15
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,
if such prospectus was timely made available by the Company pursuant to Section
3(c) hereof; (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 Registrable Securities 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, if such prospectus was
timely made available by the Company pursuant to Section 3(c) hereof; and (III)
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. 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 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, 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 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 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 such


                                      -15-
   16
Investor will 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 such Investor, which consent shall not be
unreasonably withheld; provided, further, however, that the Investor shall be
liable under this Section 6(b) for only that amount of a Claim as does not
exceed the amount of 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) 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 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 selected by the indemnifying party
but reasonably acceptable to 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


                                      -16-
   17
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. In such event, the
Company shall pay for only one separate legal counsel for the Investors; such
legal counsel shall be selected by the Investors holding a majority in interest
of the Registrable Securities included in the Registration Statement to which
the Claim relates. 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.

         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 (a) 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, (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation and (c)
contribution by any seller of Registrable Securities shall be limited in amount
to the amount by which the net amount of proceeds received by such seller from
the sale of such Registrable Securities exceeds the purchase price paid by such
seller for such Registrable Securities.

         8. REPORTS UNDER EXCHANGE ACT. With a view to making available to the
Investors the benefits of Rule 144 promulgated under the Securities 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:

                                      -17-
   18
         (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 each Investor so long as such Investor owns Registrable
Securities, 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
Investors to sell such securities pursuant to Rule 144 without registration.

         9. ASSIGNMENT OF THE REGISTRATION RIGHTS. The rights to have the
Company register Registrable Securities pursuant to this Agreement shall be
automatically assigned by the Investors to any transferee of all or any portion
of such securities (or all or any portion of the Preferred Shares) of
Registrable Securities only if: (a) 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, (b) the
Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (i) the name and address of such transferee or
assignee and (ii) the securities with respect to which such registration rights
are being transferred or assigned, (c) immediately following such transfer or
assignment the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act and applicable state securities
laws, and (d) at or before the time the Company received the written notice
contemplated by clause (b) of this sentence the transferee or assignee agrees in
writing with the Company to be bound by all of the provisions contained herein.
In connection with any such transfer the Company shall, at its sole cost and
expense, promptly after such assignment take such actions as shall be reasonably
acceptable to the Initial Investor and such transferee to assure that the
Registration Statement and related prospectus are available for use by such
transferee for sales of the Registrable Securities in respect of which the
rights to registration have been so assigned.

         10. AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Agreement
may be amended and the


                                      -18-
   19
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 Investors who hold a majority in 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) Notices required or permitted to be given hereunder shall be in
writing and shall be deemed to be sufficiently given when personally delivered
(by hand, by courier, by telephone line facsimile transmission or other means)
or sent by certified mail, return receipt requested, properly addressed and with
proper postage pre-paid (i) if to the Company, at JTS Corporation, 166 Baypointe
Parkway, San Jose, California 95134, Attention: Chief Financial Officer,
telephone line facsimile transmission No. (408) 468-1619, (ii) if to the Initial
Investor, c/o Genesee Investments, 10500 N.E. 8th Street, Suite 1920, Bellevue,
Washington 98004-4332, telephone line facsimile transmission No. (206) 462-4645
and (iii) if to any other Investor, at such address as such Investor shall have
provided in writing to the Company, or at such other address as each such party
furnishes by notice given in accordance with this Section 11(b), and shall be
effective, when personally delivered, upon receipt and, when so sent by
certified mail, four days after deposit with the United States Postal Service.

         (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 California 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


                                      -19-
   20
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.

         (e) This Agreement constitutes the entire agreement among the parties
hereto with respect to the subject matter hereof. There are no restrictions,
promises, warranties or undertakings, other than those set forth or referred to
herein. This Agreement supersedes all prior agreements and understandings among
the parties hereto with respect to the subject matter hereof.

         (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) All pronouns and any variations thereof refer to the masculine,
feminine or neuter, singular or plural, as the context may require.

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

         (i) The Company acknowledges that any failure by the Company to perform
its obligations under this Agreement, including, without limitation, the
Company's obligations under Section 3(n), or any delay in such performance could
result in damages to the Investors and the Company agrees that, in addition to
any other liability the Company may have by reason of any such failure or delay,
the Company shall be liable for all direct and consequential damages caused by
any such failure or delay.

         (j) This Agreement may be executed in two or more counterparts, each of
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 telephone line facsimile transmission of a copy of
this Agreement bearing the signature of the party so delivering this Agreement.
