hereunder, the "Initial Investors").

         WHEREAS:

         A.       In connection with the Securities Purchase Agreement by and
among the parties hereto of even date herewith (the "Securities Purchase
Agreement"), the Company has agreed, upon the terms and subject to the
conditions contained therein, to issue and sell to the Initial Investors (i)

the Company's common stock, par value $0.01 per share (the "Common Stock"), upon
the terms and subject to the limitations and conditions set forth in such
Debentures and (ii) warrants (the "Warrants") to acquire 337,268 shares of
Common Stock, upon the terms and conditions and subject to the limitations and
conditions set forth in the Warrants dated March 10, 2000; and

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

         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 each
of the Initial Investors hereby agree as follows:

         1.        DEFINITIONS.

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

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

                           (ii) "REGISTER," "REGISTERED," and "REGISTRATION"
refer to a registration effected by preparing and filing a Registration
Statement or Statements in compliance with the 1933 Act and pursuant to Rule 415
under the 1933 Act or any successor rule providing for offering securities on a
continuous basis ("RULE 415"), and the declaration or

                                        1

<PAGE>

ordering of effectiveness of such Registration Statement by the United States
Securities and Exchange Commission (the "SEC").

                           (iii)   "REGISTRABLE SECURITIES" means (a) the
Conversion Shares issued or issuable upon conversion of or otherwise pursuant to
the Debentures (including, without limitation, any shares issued or issuable
pursuant to Sections 1.3 and 1.4(e) of the Debentures and Section 2(c) herein)
(b) the Warrant Shares issued or issuable upon exercise of or otherwise pursuant
to the Warrants and (c) any shares of capital stock issued or issuable as a
dividend on or in exchange for or otherwise with respect to any of the
foregoing.

                           (iv)     "REGISTRATION STATEMENT(S)" means a
registration statement(s) of the Company under the 1933 Act.

                  b.       Capitalized terms used herein and not otherwise
defined herein shall have the respective meanings set forth in the Securities
Purchase Agreement.

         2. REGISTRATION.

                  a.       MANDATORY REGISTRATION. The Company shall prepare,
and, on or prior to the date (the "FILING DATE") which is thirty (30) days after
the date of the Closing under the Securities Purchase Agreement (the "CLOSING
DATE"), file with the SEC a Registration Statement on Form S-3 (or, if Form S-3
is not then available, on such form of Registration Statement as is then
available to effect a registration of the Registrable Securities, subject to the
consent of the Initial Investors, which consent will not be unreasonably
withheld) covering the resale of the Registrable Securities, which Registration
Statement, to the extent allowable under the 1933 Act and the rules and
regulations promulgated thereunder (including Rule 416), shall state that such
Registration Statement also covers such indeterminate number of additional
shares of Common Stock as may become issuable upon conversion of or otherwise
pursuant to the Debentures and exercise of or otherwise pursuant to the Warrants
to prevent dilution resulting from stock splits, stock dividends or similar
transactions. The number of shares of Common Stock initially included in such
Registration Statement shall be no less than one and one-half (1.5) times the
aggregate number of Conversion Shares that are then issuable upon conversion of
or otherwise pursuant to the Debentures (based on the Conversion Price (as
defined in the Debentures) then in effect) and the aggregate number of Warrant
Shares that are then issuable upon exercise of or otherwise pursuant to the
Warrants, without regard to any limitation on the Investor's ability to convert
the Debentures or exercise the Warrants. The Company acknowledges that the
number of shares initially included in the Registration Statement represents a
good faith estimate of the maximum number of shares issuable upon conversion of
or otherwise pursuant to the Debentures and exercise of or otherwise pursuant to
the Warrants. The Registration Statement (and each amendment or supplement
thereto, and each request for acceleration of effectiveness thereof) shall be
provided to (and subject to the approval of) the Initial Investors and their
counsel prior to its filing or other submission.

                                        2

                  b.       [INTENTIONALLY OMITTED]

                  c.       PAYMENTS BY THE COMPANY. The Company shall use its
best efforts to obtain effectiveness of the Registration Statement as soon as
practicable, but in any event not later than May 31, 2000 (the "REGISTRATION
DEADLINE"). If (i) the Registration Statement covering the Registrable
Securities required to be filed by the Company pursuant to Section 2(a) hereof
is not declared effective by the SEC by the Registration Deadline, or (ii) after
the Registration Statement has been declared effective by the SEC, sales of all
of the Registrable Securities cannot be made pursuant to the Registration
Statement, or (iii) the Common Stock is not listed or included for quotation on
the Nasdaq National Market ("NASDAQ"), the Nasdaq SmallCap Market ("NASDAQ
SMALLCAP"), the New York Stock Exchange (the "NYSE") or the American Stock
Exchange (the "AMEX") after being so listed or included for quotation, then the
Company will make payments to the Investors in such amounts and at such times as
shall be determined pursuant to this Section 2(c) as partial relief for the
damages to the Investors by reason of any such delay in or reduction of their
ability to sell the Registrable Securities (which remedy shall not be exclusive
of any other remedies available at law or in equity). The Company shall pay to
each holder of the Debentures or Registerable Securities an amount equal to the
then outstanding principal amount of the Debentures (and, in the case of holders
of Registrable Securities, the principal amount of Debentures from which such
Registrable Securities were converted or the aggregate exercise price paid for
such Registrable Securities upon exercise of the Warrants) ("OUTSTANDING
PRINCIPAL AMOUNT") multiplied by the Applicable Percentage (as defined below)
times the sum of: (i) the number of months (prorated for partial months) after
the Registration Deadline and prior to the date the Registration Statement is
declared effective by the SEC; PROVIDED, HOWEVER, that there shall be excluded
from such period any delays which are solely attributable to changes required by
the Investors in the Registration Statement with respect to information relating
to the Investors, including, without limitation, changes to the plan of
distribution, or to the failure of the Investors to conduct their review of the
Registration Statement pursuant to Section 3(h) below in a reasonably prompt
manner; (ii) the number of months (prorated for partial months) during the
Registration Period (as defined below) that sales of all of the Registrable
Securities cannot be made pursuant to the Registration Statement after the
Registration Statement has been declared effective (including, without
limitation, when sales cannot be made by reason of the Company's failure to
properly supplement or amend the prospectus included therein in accordance with
the terms of this Agreement (including Section 3(b) hereof or otherwise), but
excluding any days during an Allowed Delay (as defined in Section 3(f)); and
(iii) the number of months (prorated for partial months) that the Common Stock
is not listed or included for quotation on the Nasdaq, Nasdaq SmallCap, NYSE or
AMEX or that trading thereon is halted after the Registration Statement has been
declared effective. The term "APPLICABLE PERCENTAGE" means 1.5 hundredths
(.015). (For example, if the Registration Statement becomes effective one (1)
month after the Registration Deadline, the Company would pay $15,000 for each
$1,000,000 of Outstanding Principal Amount. If thereafter, sales of all of the
Registrable Securities could not be made pursuant to the Registration Statement
for an additional period of one (1) month, the Company would pay an additional
$15,000 for each $1,000,000 Outstanding Principal Amount. Such amounts shall be
paid in cash within five (5) days after the end of each period that gives rise
to such obligation, PROVIDED that, if any such

                                        3

<PAGE>

period extends for more than thirty (30) days, interim payments shall be made
for each such thirty (30) day period, PROVIDED, FURTHER, that, if such amounts
are not paid within the period specified, at each Investor's option, such
amounts may be added to the Conversion Amount (as defined in the Debentures) of
the Debentures and thereafter be convertible into Common Stock at the
"CONVERSION PRICE" (as defined in the Debentures) in accordance with the terms
of the Debentures. Any shares of Common Stock issued upon conversion of such
amounts shall be Registrable Securities. Nothing herein shall limit an
Investor's right to pursue damages for the failure to timely obtain
effectiveness of the Registration Statement by the Registration Deadline or to
thereafter maintain the effectiveness of the Registration Statement as required
pursuant to this Agreement or to maintain the listing of the Common Stock;
PROVIDED, HOWEVER, that, except as set forth in Section 11(k) hereof, each
Investor's right to pursue actual damages for the failure of the Company to
obtain effectiveness of the Registration Statement by the Registration Deadline
during the initial sixty (60) days following the Registration Deadline shall be
limited to the amounts set forth in this Section 2(c).

                  d.       PIGGY-BACK REGISTRATIONS. Subject to the last
sentence of this Section 2(d), if at any time prior to the expiration of the
Registration Period (as hereinafter defined) the Company shall determine to file
with the SEC a Registration Statement relating to an offering for its own
account or the account of others under the 1933 Act of any of its equity
securities (other than on Form S-4 or Form S-8 or their then equivalents
relating to equity securities to be issued solely in connection with any
acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans), the Company shall
send to each Investor who is entitled to registration rights under this Section
2(d) written notice of such determination and, if within fifteen (15) days after
the effective date of such notice, such Investor shall so request in writing,
the Company shall include in such Registration Statement all or any part of the
Registrable Securities such Investor requests to be registered, except that if,
in connection with any underwritten public offering for the account of the
Company, the managing underwriter(s) thereof shall impose a limitation on the
number of shares of Common Stock which may be included in the Registration
Statement because, in such underwriter(s)' judgment, marketing or other factors
dictate such limitation is necessary to facilitate public distribution, then the
Company shall be obligated to include in such Registration Statement only such
limited portion of the Registrable Securities with respect to which such
Investor has requested inclusion hereunder as the underwriter shall permit. Any
exclusion of Registrable Securities shall be made pro rata among the Investors
seeking to include Registrable Securities in proportion to the number of
Registrable Securities sought to be included by such Investors; PROVIDED,
HOWEVER, that the Company shall not exclude any Registrable Securities unless
the Company has first excluded all outstanding securities, the holders of which
are not entitled by contract to inclusion of such securities in such
Registration Statement or are not entitled to pro rata inclusion with the
Registrable Securities; and PROVIDED, FURTHER, HOWEVER, that, after giving
effect to the immediately preceding proviso, any exclusion of Registrable
Securities shall be made pro rata with holders of other securities having the
contractual right to include such securities in the Registration Statement other
than holders of securities entitled to inclusion of their securities in such
Registration Statement by reason of demand registration rights. No right to
registration of Registrable Securities under this Section 2(d) shall be
construed to limit any

                                        4

<PAGE>

registration required under Section 2(a) hereof. If an offering in connection
with which an Investor is entitled to registration under this Section 2(d) is an
underwritten offering, then each Investor whose Registrable Securities are
included in such Registration Statement shall, unless otherwise agreed by the
Company, offer and sell such Registrable Securities in an underwritten offering
using the same underwriter or underwriters and, subject to the provisions of
this Agreement, on the same terms and conditions as other shares of Common Stock
included in such underwritten offering. Notwithstanding anything to the contrary
set forth herein, the registration rights of the Investors pursuant to this
Section 2(d) shall only be available in the event the Company fails to timely
file, obtain effectiveness or maintain effectiveness of any Registration
Statement to be filed pursuant to Section 2(a) in accordance with the terms of
this Agreement.

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

         3.       OBLIGATIONS OF THE COMPANY.

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

                  a.       The Company shall prepare promptly, and file with the
SEC as soon as practicable after the Closing Date (but no later than the Filing
Date), a Registration Statement with respect to the number of Registrable
Securities provided in Section 2(a), and thereafter use its best efforts to
cause such Registration Statement relating to Registrable Securities to become
effective as soon as possible after such filing (but in no event later than the
Registration Deadline), and keep the Registration Statement effective pursuant
to Rule 415 at all times until such date as is the earlier of (i) the date on
which all of the Registrable Securities have been sold and (ii) the date on
which the Registrable Securities (in the opinion of counsel to the Initial
Investors) may be immediately sold to the public without registration or
restriction (including without limitation as to volume by each holder thereof)
under the 1933 Act (the "REGISTRATION PERIOD"), 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 not misleading.

                  b.       The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) and supplements to the
Registration Statements and the prospectus used in connection with the
Registration Statements as may be necessary to keep the Registration Statements
effective at all times during the Registration Period, and, during such period,
comply with the provisions of the 1933 Act with respect to the disposition of
all Registrable Securities of the Company covered by the Registration Statements

                                        5

<PAGE>

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 Statements. In the event that on any
Trading Day (as defined in the Debentures) (the "REGISTRATION TRIGGER DATE") the
number of shares available under a Registration Statement filed pursuant to this
Agreement is insufficient to cover all of the Registrable Securities issued or
issuable upon conversion of or otherwise pursuant to the Debentures (based on
the Conversion Price (as defined in the Debentures) then in effect) and exercise
of or otherwise pursuant to the Warrants, in each case without giving effect to
any limitations on the Investors' ability to convert the Debentures or exercise
the Warrants, the Company shall amend the Registration Statement, or file a new
Registration Statement (on the short form available therefore, if applicable),
or both, so as to cover one hundred fifty percent (150%) of all of the
Registrable Securities so issued or issuable (without giving effect to any
limitations on conversion contained in the Debentures or exercise contained in
the Warrants) as of the Registration Trigger Date, in each case, as soon as
practicable, but in any event within twenty (20) business days after the
necessity therefor arises (based on the market price of the Common Stock and
other relevant factors on which the Company reasonably elects to rely). The
Company shall use its best efforts to cause such amendment and/or new
Registration Statement to become effective as soon as practicable following the
filing thereof, but in any event within sixty (60) days of the Registration
Trigger Date. The provisions of Section 2(c) above shall be applicable with
respect to the Company's obligations under this Section 3(b).

                  c.       The Company shall furnish to each Investor whose
Registrable Securities are included in a Registration Statement and its legal
counsel (i) promptly after the same is prepared and publicly distributed, filed
with the SEC, or received by the Company, one copy of each Registration
Statement and any amendment thereto, each preliminary prospectus and prospectus
and each amendment or supplement thereto, and, in the case of the Registration
Statement referred to in Section 2(a), 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, in each case relating to such Registration
Statement (other than any portion of any thereof which contains information for
which the Company has sought confidential treatment), and (ii) such number of
copies of a prospectus, including a preliminary prospectus, and all amendments
and supplements thereto and such other documents as such Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such Investor. The Company will immediately notify each Investor by
facsimile of the effectiveness of each Registration Statement or any
post-effective amendment. The Company will promptly respond to any and all
comments received from the SEC, with a view towards causing each Registration
Statement or any amendment thereto to be declared effective by the SEC as soon
as practicable and shall file an acceleration request as soon as practicable,
but no later than three (3) business days (the "ACCELERATION REQUEST DEADLINE"),
following the resolution or clearance of all SEC comments or, if applicable,
following notification by the SEC that any such Registration Statement or any
amendment thereto will not be subject to review.

                  d.       The Company shall use reasonable efforts to (i)
register and qualify the Registrable Securities covered by the Registration
Statements under such other securities or

                                        6

<PAGE>

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

                  f.       As promptly as practicable after becoming aware of
such event, the Company shall notify each Investor of the happening of any
event, of which the Company has knowledge, as a result of which the prospectus
included in any Registration Statement, as then in effect, includes an untrue
statement of a material fact or omission to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
use its best efforts promptly to prepare a supplement or amendment to any
Registration Statement to correct such untrue statement or omission, and deliver
such number of copies of such supplement or amendment to each Investor as such
Investor may reasonably request; provided that, for not more than twenty (20)
consecutive days (or a total of not more than sixty (60) days in any twelve (12)
month period), the Company may delay the disclosure of material non-public
information concerning the Company (as well as prospectus or Registration
Statement updating) the disclosure of which at the time is not, in the good
faith opinion of the Company, in the best interests of the Company (an "ALLOWED
DELAY"); provided, further, that the Company shall promptly (i) notify the
Investors in writing of the existence of (but in no event, without the prior
written consent of an Investor, shall the Company disclose to such Investor any
of the facts or circumstances regarding) material non-public information giving
rise to an Allowed Delay and (ii) advise the Investors in writing to cease all
sales under such Registration Statement until the end of the Allowed Delay. Upon
expiration of the Allowed Delay, the Company shall again be bound by the first
sentence of this Section 3(f) with respect to the information giving rise
thereto.

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

                                        7

<PAGE>

                  h.       The Company shall permit a single firm of counsel
designated by the Initial Investors to review such Registration Statement and
all amendments and supplements thereto (as well as all requests for acceleration
or effectiveness thereof) a reasonable period of time prior to their filing with
the SEC (not less than three (3) business days but not more then five (5)
business days) and not file any document in a form to which such counsel
reasonably objects and will not request acceleration of such Registration
Statement without prior notice to such counsel. The sections of such
Registration Statement covering information with respect to the Investors, the
Investor's beneficial ownership of securities of the Company or the Investors
intended method of disposition of Registrable Securities shall conform to the
information provided to the Company by each of the Investors.

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

                  j.       At the request of any Investor participating in an
underwritten offering pursuant to Section 2(d), the Company shall furnish, on
the date that Registrable Securities are delivered to an underwriter for sale in
connection with any Registration Statement pursuant to Section 2(d), (i) an
opinion, dated as of such date, from counsel representing the Company for
purposes of such Registration Statement, in form, scope and substance as is
customarily given in an underwritten public offering, addressed to the
underwriters, if any, and the Investors and (ii) a letter, dated such date, from
the Company's independent certified public accountants in form and substance as
is customarily given by independent certified public accountants to underwriters
in an underwritten public offering, addressed to the underwriters, if any, and
the Investors.

                  k.       The Company shall make available for inspection by
(i) any Investor, (ii) one firm of attorneys and one firm of accountants or
other agents retained by the Initial Investors and (iii) one firm of attorneys
and one firm of accountants or other agents retained by all other Investors
(collectively, the "INSPECTORS") all pertinent financial and other records, and
pertinent corporate documents and properties of the Company (collectively, the
"RECORDS"), as shall be reasonably deemed necessary by each Inspector to enable
each Inspector to exercise its due diligence responsibility, and cause the
Company's officers, directors and employees to supply all information which any
Inspector may reasonably request for purposes of such due diligence; PROVIDED,
HOWEVER, that each Inspector shall hold in confidence and shall not make any
disclosure (except to an Investor) of any Record or other information which the
Company determines in good faith to be confidential, and of which determination
the Inspectors are so notified, unless (a) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in any Registration
Statement, (b) the release of such Records is ordered pursuant to a subpoena or
other order from a court or government body of competent jurisdiction, or (c)
the information in such Records has been made generally available to the public
other than by disclosure in violation of this or any other agreement. The
Company shall

                                        8

<PAGE>

not be required to disclose any confidential information in such Records to any
Inspector until and unless such Inspector shall have entered into
confidentiality agreements (in form and substance satisfactory to the Company)
with the Company with respect thereto, substantially in the form of this Section
3(k). Each Investor agrees that it shall, upon learning that disclosure of such
Records is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at its expense, to undertake appropriate action to prevent
disclosure of, or to obtain a protective order for, the Records deemed
confidential. Nothing herein (or in any other confidentiality agreement between
the Company and any Investor) shall be deemed to limit the Investor's ability to
sell Registrable Securities in a manner which is otherwise consistent with
applicable laws and regulations.

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

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

                  n.       The Company shall provide a transfer agent and
registrar, which may be a single entity, for the Registrable Securities not
later than the effective date of the Registration Statement.

                  o.       The Company shall cooperate with the Investors who
hold Registrable Securities being offered and the managing underwriter or
underwriters, if any, to facilitate the timely preparation and delivery of
certificates (not bearing any restrictive legends) representing Registrable
Securities to be offered pursuant to such Registration Statement and enable such
certificates to be in such denominations or amounts, as the case may be, as the

                                        9

<PAGE>

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 (3)
business days after a Registration Statement which includes Registrable
Securities is ordered effective by the SEC, the Company shall deliver, and shall
cause legal counsel selected by the Company to deliver, to the transfer agent
for the Registrable Securities (with copies to the Investors whose Registrable
Securities are included in such Registration Statement) an instruction in the
form attached hereto as EXHIBIT 1 and an opinion of such counsel in the form
attached hereto as EXHIBIT 2.

                  p.       At the request of the holders of a
majority-in-interest of the Registrable Securities, the Company shall prepare
and file with the SEC such amendments (including post-effective amendments) and
supplements to a Registration Statement and any prospectus used in connection
with the Registration Statement as may be necessary in order to change the plan
of distribution set forth in such Registration Statement.

                  q.       The Company shall not, and shall not agree to, allow
the holders of any securities of the Company to include any of their securities
in any Registration Statement under Section 2(a) hereof or any amendment or
supplement thereto under Section 3(b) hereof without the consent of the holders
of a majority-in-interest of the Registrable Securities. In addition, the
Company shall not offer any securities for its own account or the account of
others in any Registration Statement under Section 2(a) hereof or any amendment
or supplement thereto under Section 3(b) hereof without the consent of the
holders of a majority-in-interest of the Registrable Securities.

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

                  s.       The Company shall comply with all applicable laws
related to a Registration Statement and offering and sale of securities and all
applicable rules and regulations of governmental authorities in connection
therewith (including without limitation the 1933 Act and the 1934 Act and the
rules and regulations promulgated by the SEC).

         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

                                       10

<PAGE>

such Registrable Securities and shall execute such documents in connection with
such registration as the Company may reasonably request. At least three (3)
business days prior to the first anticipated filing date of the Registration
Statement, the Company shall notify each Investor of the information the Company
requires from each such Investor.

                  b.       Each Investor, by such Investor's acceptance of the
Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of the
Registration Statements 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 Statements.

                  c.       In the event of an underwritten offering pursuant to
Section 2(d) in which any Registrable Securities are to be included, each
Investor agrees to enter into and perform such Investor's obligations under an
underwriting agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations, with the
managing underwriter of such offering and take such other actions as are
reasonably required in order to expedite or facilitate the disposition of the
Registrable Securities, unless such Investor has notified the Company in writing
of such Investor's election to exclude all of such Investor's Registrable
Securities from such Registration Statement.

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

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

         5.       EXPENSES OF REGISTRATION.

         All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3,

                                       11

<PAGE>

including, without limitation, all registration, listing and qualification fees,
printers and accounting fees, the fees and disbursements of counsel for the
Company, and the reasonable fees and disbursements of one counsel selected by
the Initial Investors pursuant to Sections 2(b) and 3(h) hereof shall be borne
by the Company.

         6.       INDEMNIFICATION.

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

                  a.       To the extent permitted by law, the Company will
indemnify, hold harmless and defend (i) each Investor who holds such Registrable
Securities, (ii) the directors, officers, partners, employees, agents and each
person who controls any Investor within the meaning of the 1933 Act or the
Securities Exchange Act of 1934, as amended (the "1934 ACT"), if any, (iii) any
underwriter (as defined in the 1933 Act) for the Investors in connection with an
underwritten offering pursuant to Section 2(d) hereof, and (iv) the directors,
officers, partners, employees and each person who controls any such underwriter
within the meaning of the 1933 Act or the 1934 Act, if any (each, an
"INDEMNIFIED PERSON"), against any joint or several losses, claims, damages,
liabilities or expenses (collectively, together with actions, proceedings or
inquiries by any regulatory or self-regulatory organization, whether commenced
or threatened, in respect thereof, "CLAIMS") to which any of them may become
subject insofar as such Claims arise out of or are based upon: (i) any untrue
statement or alleged untrue statement of a material fact in a Registration
Statement or the omission or alleged omission to state therein a material fact
required to be stated or necessary to make the statements therein not
misleading; (ii) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus if used prior to the effective date
of such Registration Statement, or contained in the final prospectus (as amended
or supplemented, if the Company files any amendment thereof or supplement
thereto with the SEC) or the omission or alleged omission to state therein any
material fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading; or
(iii) any violation or alleged violation by the Company of the 1933 Act, the
1934 Act, any other law, including, without limitation, any state securities
law, or any rule or regulation thereunder relating to the offer or sale of the
Registrable Securities (the matters in the foregoing clauses (i) through (iii)
being, collectively, "VIOLATIONS"). Subject to the restrictions set forth in
Section 6(c) with respect to the number of legal counsel, the Company shall
reimburse the Indemnified Person, promptly as such expenses are incurred and are
due and payable, for any reasonable legal fees or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Company by any Indemnified Person
or underwriter for such Indemnified Person expressly for use in connection with
the preparation of such Registration Statement or any such amendment thereof or
supplement thereto; (ii) shall not apply to amounts paid in settlement of

                                       12

<PAGE>

any Claim if such settlement is effected without the prior written consent of
the Company, which consent shall not be unreasonably withheld; and (iii) with
respect to any preliminary prospectus, shall not inure to the benefit of any
Indemnified Person if the untrue statement or omission of material fact
contained in the preliminary prospectus was corrected on a timely basis in the
prospectus, as then amended or supplemented, such corrected prospectus was
timely made available by the Company pursuant to Section 3(c) hereof, and the
Indemnified Person was promptly advised in writing not to use the incorrect
prospectus prior to the use giving rise to a Violation and such Indemnified
Person, notwithstanding such advice, used it. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnified Person and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 9.

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

                  c.       Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action (including any

                                       13

<PAGE>

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

         7.       CONTRIBUTION.

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

         8.       REPORTS UNDER THE 1934 ACT.

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

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

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

                  c.      furnish to each Investor so long as such Investor
owns Registrable Securities, promptly upon request, (i) a written statement by
the Company that it has complied with the reporting requirements of Rule 144,
the 1933 Act and the 1934 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 REGISTRATION RIGHTS.

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

                                       15

         10.      AMENDMENT OF REGISTRATION RIGHTS.

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

         11.      MISCELLANEOUS.

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

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

                  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 governed by and construed in
accordance with the laws of the State of Delaware applicable to agreements made
and to be performed in the State of Delaware (without regard to principles of
conflict of laws). Both parties irrevocably consent to the jurisdiction of the
United States federal courts and the state courts located in Delaware with
respect to any suit or proceeding based on or arising under this Agreement, the
agreements entered into in connection herewith or the transactions contemplated
hereby or thereby and irrevocably agree that all claims in respect of such suit
or proceeding may be determined in such courts. Both parties irrevocably waive
the defense of an inconvenient forum to the maintenance of such suit or
proceeding. Both parties further agree that service of process upon a party
mailed by first class mail shall be deemed in every respect effective service of
process upon the party in any such suit or proceeding. Nothing herein shall
affect either party's right to serve process in any other manner permitted by
law. Both parties agree that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on such judgment or in any other lawful manner.

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

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

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

                  h.       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

                                       17

<PAGE>

agreement. This Agreement, once executed by a party, may be delivered to the
other party hereto by facsimile transmission of a copy of this Agreement bearing
the signature of the party so delivering this Agreement.

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

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

                  k.      The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to each Investor by vitiating
the intent and purpose of the transactions contemplated hereby. Accordingly, the
Company acknowledges that the remedy at law for breach of its obligations
hereunder will be inadequate and agrees, in the event of a breach or threatened
breach by the Company of any of the provisions hereunder, that each Investor
shall be entitled, in addition to all other available remedies in law or in
equity, to an injunction or injunctions to prevent or cure breaches of the
provisions of this Agreement and to enforce specifically the terms and
provisions hereof, without the necessity of showing economic loss and without
any bond or other security being required.

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

                  m.       In the event that any provision of this Agreement is
invalid or unenforceable under any applicable statute or rule of law, then such
provision shall be deemed inoperative to the extent that it may conflict
therewith and shall be deemed modified to conform with such statute or rule of
law. Any provision hereof which may prove invalid or unenforceable under any law
shall not affect the validity or enforceability of any other provision hereof.

                  n.       The initial number of Registrable Securities included
in any Registration Statement and each increase to the number of Registrable
Securities included therein shall be allocated pro rata among the Investors
based on the number of Registrable Securities held by each Investor at the time
of such establishment or increase, as the case may be. In the event an Investor
shall sell or otherwise transfer any of such holder's Registrable Securities,
each transferee shall be allocated a pro rata portion of the number of
Registrable Securities included in a Registration Statement for such transferor.
Any shares of Common Stock included on a Registration Statement and which remain
allocated to any person or entity which does not hold any Registrable Securities
shall be allocated to the remaining Investors, pro rata based on the

                                       18

<PAGE>

number of shares of Registrable Securities then held by such Investors. For the
avoidance of doubt, the number of Registrable Securities held by an Investor
shall be determined as if all the Debentures and Warrants then outstanding and
held by an Investor were converted into or exercised for Registrable Securities.

                       AMENDMENT NO. 1 TO CREDIT AGREEMENT

         This Agreement (this "Agreement") is made the 25th day of June, 1997 by
