     7.   Registration Rights and "Piggy-Back" Registration Rights.
          --------------------------------------------------------

          (a)   Within forty-five (45) days after the Final Closing Date

shall, at its sole cost and expense, prepare and file a registration statement
("Registration Statement") on the appropriate form with the SEC with respect to
the shares of Common Stock sold pursuant to the Memorandum and the PAW Exercise
Shares, and such additional shares of Common Stock that may be issued pursuant
to the anti-dilution rights contained in the Placement Agent Warrants and as set
forth below in this Section 7(a) (collectively, the "Registrable Securities"),
time being of the essence. The Company will use its best efforts to have such
Registration Statement declared effective as soon as possible after filing, and
to keep such Registration Statement current and effective for at least three (3)
years from the Final Closing Date or until such earlier date as all of the
Registrable Securities registered pursuant to such Registration Statement shall
have been sold. Notwithstanding anything to the contrary contained herein, if
such Registration Statement shall not be filed with the SEC within 45days after
the Final Closing Date or the Registration Statement shall not be declared
effective within 120 days after the Final Closing Date (regardless of whether
the Maximum Amount shall have been sold), then (i) with respect to the failure
to file the Registration Statement within 45 days of the Final Closing Date, the
registered holders of such Registrable Securities (including transferees
authorized under applicable securities laws; hereinafter, collectively the
"Registered Holders") shall be entitled at no cost to additional shares of
Common Stock from the Company ("Additional Shares") equal to the product of
three (3%) percent of the number of Registrable Securities owned by each such
holder, and the number of thirty (30) day periods, or any part thereof, beyond
said forty-five (45) day period, until the initial Registration Statement
described herein covering the Registrable Securities is filed with the SEC,
and/or (ii) with respect to the Registration Statement not being declared
effective within 120 days of the Final Closing Date, the Registered Holders
shall be entitled at no cost to Additional Shares equal to the product of two
(2%) percent of the number of Registrable Securities owned by each such holder,
and the number of thirty (30) day periods, or any part thereof, beyond said 120
day period, until the initial Registration Statement described herein covering
the Registrable Securities is declared effective. The maximum number of
Additional Shares issuable pursuant to this provision is 36%.

          (b)   In the event the Company effects any registration under the 1933
Act of any Registrable Securities pursuant to Sections 7(a) above or 7(g) below,
the Company shall indemnify, to the extent permitted by law, and hold harmless
any Registered Holder whose Registrable Securities are included in such
registration statement (each, a "Seller"), any underwriter, any officer,
director, employee or agent of any Seller or underwriter, and each other person,
if any, who controls any Seller or underwriter within the meaning of Section 15
of the 1933 Act, against any losses, claims, damages or liabilities, judgment,
fines, penalties, costs and expenses, joint or several, or actions in respect
thereof (collectively, the "Claims"), to which each such indemnified party
becomes subject, under the 1933 Act or otherwise, insofar as such Claims arise
out of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the registration statement or prospectus or any
amendment or supplement thereto or any document filed under a state securities
or blue sky law (collectively, the "Registration Documents") or insofar as such
Claims

                                      -9-
<PAGE>

arise out of or are based upon the omission or alleged omission to state in any
Registration Document a material fact required to be stated therein or necessary
to make the statements made therein not misleading, and will reimburse any such
indemnified party for any legal or other expenses reasonably incurred by such
indemnified party in investigating or defending any such Claim; provided that
the Company shall not be liable in any such case to a particular indemnified
party to the extent such Claim is based upon an untrue statement or alleged
untrue statement of a material fact or omission or alleged omission of a
material fact made in any Registration Document in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such indemnified party specifically for use in the preparation of such
Registration Document.

          (c)       In connection with any registration statement in which any
Seller is participating, each Seller, severally and not jointly, shall
indemnify, to the extent permitted by law, and hold harmless the Company, each
of its directors, each of its officers who have signed the registration
statement, each other person, if any, who controls the Company within the
meaning of Section 15 of the 1933 Act, each other Seller and each underwriter,
any officer, director, employee or agent of any such other Seller or underwriter
and each other person, if any, who controls such other Seller or underwriter
within the meaning of Section 15 of the 1933 Act against any Claims to which
each such indemnified party may become subject under the 1933 Act or otherwise,
insofar as such Claims (or actions in respect thereof) are based upon any untrue
statement or alleged untrue statement of any material fact contained in any
Registration Document, or insofar as any Claims are based upon the omission or
alleged omission to state in any Registration Document a material fact required
to be stated therein or necessary to make the statements made therein not
misleading, and will reimburse any such indemnified party for any legal or other
expenses reasonably incurred by such indemnified party in investigating or
defending any such Claim; provided, however, that such indemnification or
reimbursement shall be payable only if, and to the extent that, any such Claim
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Registration Document in reliance
upon and in conformity with written information furnished to the Company by the
Seller specifically for use in the preparation thereof.

          (d)       Any person entitled to indemnification under Sections 7(b)
or 7(c) above shall notify promptly the indemnifying party in writing of the
commencement of any Claim if a claim for indemnification in respect thereof is
to be made against an indemnifying party under this Section 7(d), but the
omission of such notice shall not relieve the indemnifying party from any
liability which it may have to any indemnified party under Sections 7(b) or 7(c)
above, except to the extent that such failure shall materially adversely affect
any indemnifying party or its rights hereunder. In case any action is brought
against the indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
in, and, to the extent that it chooses, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party; and, after notice from
the indemnifying party to the indemnified party that it so chooses, the
indemnifying party shall not be liable for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof; provided, however, that (i) if the indemnifying party fails to take
reasonable steps necessary to defend diligently the Claim

                                     -10-
<PAGE>

within twenty (20) days after receiving notice from the indemnified party such
that the indemnified party believes it has failed to do so; (ii) if the
indemnified party who is a defendant in any action or proceeding which is also
brought against the indemnifying party reasonably shall have concluded that
there are legal defenses available to the indemnified party which are not
available to the indemnifying party; or (iii) if representation of both parties
by the same counsel is otherwise inappropriate under applicable standards of
professional conduct, the indemnified party shall have the right to assume or
continue its own defense as set forth above (but with no more than one firm of
counsel for all indemnified parties, except to the extent any indemnified party
or parties reasonably shall have concluded that there are legal defenses
available to such party or parties which are not available to the other
indemnified parties or to the extent representation of all indemnified parties
by the same counsel is otherwise inappropriate under applicable standards of
professional conduct) and the indemnifying party shall be liable for any
reasonable expenses therefor; provided, that no indemnifying party shall be
subject to any liability for any settlement of a Claim made without its consent
(which may not be unreasonably withheld, delayed or conditioned). If the
indemnifying party assumes the defense of any Claim hereunder, such indemnifying
party shall not enter into any settlement without the consent of the indemnified
party if such settlement attributes liability to the indemnified party.

          (e)       If for any reason the indemnity provided in Sections 7(b) or
7(c) above is unavailable, or is insufficient to hold harmless, an indemnified
party, then the indemnifying party shall contribute to the amount paid or
payable by the indemnified party as a result of any Claim in such proportion as
is appropriate to reflect the relative benefits received by the indemnifying
party on the one hand and the indemnified party on the other from the
transactions contemplated by this Agreement. If, however, the allocation
provided in the immediately preceding sentence is not permitted by applicable
law, then each indemnifying party shall contribute to the amount paid or payable
by such indemnified party in such proportion as is appropriate to reflect not
only such relative benefits but also the relative fault of the indemnifying
party and the indemnified party as well as any other relevant equitable
considerations. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the indemnifying party or by the indemnified party and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The amount paid or payable in
respect of any Claim shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such Claim. Notwithstanding the foregoing, no underwriter or
controlling person thereof, if any, shall be required to contribute, in respect
of such underwriter's participation as an underwriter in the offering, any
amount in excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The

                                     -11-
<PAGE>

obligation of any underwriters to contribute pursuant to this Section 7(e) shall
be several in proportion to their respective underwriting commitments and not
joint.

          (f)       The provisions of Sections 7(b) through 7(e) of this
Agreement shall be in addition to any other rights to indemnification or
contribution which any indemnified party may have pursuant to law or contract
and shall remain operative and in full force and effect regardless of any
investigation made or omitted by or on behalf of any indemnified party and shall
survive the transfer of the Registrable Securities by any such party.

          (g)       The Sellers shall have certain "piggy-back" registration
rights with respect to the Registrable Securities as hereinafter provided:

                    A.        If at any time after the Final Closing Date and
prior to the date that the Registrable Securities are registered under the 1933
Act pursuant to Section 7(a) above, the Company shall file with the SEC a
registration statement under the 1933 Act (other than a registration statement
on Form S-4 or Form S-8 or any successor thereof, or filed in connection with an
exchange offer or an offer of securities solely to the Company's existing
shareholders) registering any shares of Common Stock, the Company shall give
written notice to each Seller thereof prior to such filing.

                    B.        Within fifteen (15) days after such notice from
the Company, each Seller shall give written notice to the Company whether or not
the Seller desires to have all of the Seller's Registrable Securities included
in the registration statement. If a Seller fails to give such notice within such
period, such Seller shall not have the right to have Seller's Registrable
Securities registered pursuant to such registration statement. If a Seller gives
such notice, then the Company shall include such Seller's Registrable Securities
in the registration statement, at the Company's sole cost and expense, subject
to the remaining terms of this Section 7(g); provided, however, that each Seller
shall pay all underwriting discounts, commissions, and transfer taxes relating
to the sale of such Seller's Registrable Securities, as well as his, her or its
own counsel fees, if any, relating to the sale of the Seller's Registrable
Securities.

                    C.        If the registration statement relates to an
underwritten offering, and the underwriter in its sole discretion shall
determine in writing that the total number of shares of Common Stock to be
included in the offering, including the Registrable Securities, shall exceed the
amount which the underwriter in its sole discretion deems to be appropriate for
the offering, the number of shares of the Registrable Securities shall be
reduced pro rata (based on the number of Registered Securities requested to be
included). The Sellers shall enter into such agreements as may be reasonably
required by the underwriters.

                    D.        The Sellers each shall have two (2) opportunities
to have the Registrable Securities registered under this Section 7(g).

                                     -12-
<PAGE>

               E.    The Sellers shall furnish in writing to the Company such
information as the Company shall reasonably require in connection with a
registration statement.

               F.    The Company may, at any time and in its sole discretion,
decide not to proceed with the filing of a registration statement which may have
given rise to "piggy-back" rights under this Section 7(g) or may at any time
terminate or suspend such registration, in which event each Seller's rights
under this Section 7 as to the number of opportunities to "piggy-back" shall be
reset.

          (h) If and whenever the Company is required by the provisions of
Section 7(a) to use its best efforts to register any Registrable Securities
under the 1933 Act, the Company shall, as expeditiously as possible under the
circumstances and subject to the terms of this Section 7:

               A.    Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective as soon as possible after filing and
remain effective.

               B.    Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement current and
effective and to comply with the provisions of the 1933 Act, and any regulations
promulgated thereunder, with respect to the sale or disposition of all
Registrable Securities covered by the registration statement required to effect
the distribution of the securities, but in no event shall the Company be
required to do so for a period of more than three (3) years following the Final
Closing Date.

               C.    Furnish to the Sellers participating in the offering,
copies (in reasonable quantities) of summary, preliminary, final, amended or
supplemented prospectuses, in conformity with the requirements of the 1933 Act
and any regulations promulgated thereunder, and other documents as reasonably
may be required in order to facilitate the disposition of the securities, but
only while the Company is required under the provisions hereof to keep the
registration statement current.

               D.    Use its best efforts to register or qualify the Registrable
Securities covered by such registration statement under such other securities or
blue sky laws of such jurisdictions of the United States as the Sellers
participating in the offering shall reasonably request, and do any and all other
acts and things which may be reasonably necessary to enable each participating
Seller to consummate the disposition of the Registrable Securities in such
jurisdictions.

               E.    Notify each Seller selling Registrable Securities, at any
time when a prospectus relating to any such Registrable Securities covered by
such registration statement is required to be delivered under the 1933 Act, of
the Company's becoming aware that the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the

                                      -13-
<PAGE>

statements therein not misleading in the light of the circumstances then
existing, and promptly prepare and furnish to each such Seller selling
Registrable Securities a reasonable number of copies of a prospectus
supplemented or amended so that, as thereafter delivered to the purchasers of
such Registrable Securities, such prospectus shall not include an 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 in the
light of the circumstances then existing.

               F.    As soon as practicable after the effective date of the
registration statement, and in any event within eighteen (18) months thereafter,
make generally available to Sellers participating in the offering an earnings
statement (which need not be audited) covering a period of at least twelve (12)
consecutive months beginning after the effective date of the registration
statement which earnings statement shall satisfy the provisions of Section 11(a)
of the 1933 Act, including, at the Company's option, Rule 158 thereunder. To the
extent that the Company files such information with the SEC in satisfaction of
the foregoing, the Company need not deliver the above referenced earnings
statement to Sellers.

               G.    Upon request, deliver promptly to counsel of each Seller
participating in the offering copies of all correspondence between the SEC and
the Company, its counsel or auditors and all memoranda relating to discussions
with the SEC or its staff with respect to the registration statement and permit
each such Seller to do such investigation at such Seller's sole cost and
expense, upon reasonable advance notice, with respect to information contained
in or omitted from the registration statement as it deems reasonably necessary.
Each Seller agrees that it will use its best efforts not to interfere
unreasonably with the Company's business when conducting any such investigation
and each Seller shall keep any such information received pursuant to this
Section 7(h)G confidential.

               H.    Provide a transfer agent located in the United States for
all such Registrable Securities covered by such registration statement not later
than the effective date of such registration statement.

               I.    List the Registrable Securities covered by such
registration statement on such market or exchanges and/or on Nasdaq as the
Common Stock is then currently listed upon.

               J.    Pay all Registration Expenses (as defined below) incurred
in connection with a registration of Registrable Securities, whether or not such
registration statement shall become effective; provided that each Seller shall
pay all underwriting discounts, commissions and transfer taxes, and their own
counsel fees, if any, relating to the sale or disposition of such Seller's
Registrable Securities pursuant to a registration statement. As used herein,
"Registration Expenses" means any and all reasonable and customary expenses
incident to performance of or compliance with the registration rights set forth
herein, including, without limitation, (i) all SEC and stock exchange or
National Association of Securities Dealers, Inc. registration and filing fees,
(ii) all fees and expenses of complying with state securities or blue sky laws
(including reasonable fees and disbursements of counsel for the underwriters in
connection with blue sky qualifications of the

                                      -14-
<PAGE>

Registrable Securities but no other expenses of the underwriters or their
counsel), (iii) all printing, messenger and delivery expenses, and (iv) the
reasonable fees and disbursements of counsel for the Company and the Company's
independent public accountants.

          (i) The Company acknowledges that there is no adequate remedy at law
for failure by it to comply with the provisions of this Section 7 and that such
failure would not be adequately compensable in damages, and therefore agrees
that its agreements contained in this Section 7 may be specifically enforced. In
the event that the Company shall fail to file such registration statement when
required pursuant to Section 7(a) above or to keep any registration statement
effective as provided in this Section or otherwise fails to comply with its
obligations and agreements in this Section 7, then, in addition to any other
rights or remedies Sellers may have at law or in equity, including without
limitation, the right of rescission, the Company shall indemnify and hold
harmless each holder of Placement Agent Warrants from and against any and all
manner or loss which they may incur as a result of such failure. In addition,
the Company shall also reimburse such holders for any and all reasonable legal
fees and expenses incurred by them in successfully enforcing their rights
pursuant to this Section 7, regardless of whether any litigation was commenced;
provided, however, that the Company shall not be liable for the fees and
expenses of more than one law firm, which firm shall be designated by the
Placement Agent.

     8.   Conditions.  The following obligations of the Company shall be
          ----------
satisfied or fulfilled on or prior to the date of each Closing, unless otherwise
agreed to in writing by the Placement Agent:

          (a)   The Company shall have delivered to the Placement Agent, at the

restated and amended articles of incorporation of the Company, as currently in
effect, certified by the Secretary of State or other appropriate authority of
the state where the Company is incorporated; (iii) by-laws of the Company

          (b)   There shall have occurred no material adverse event affecting
the Company or any of its businesses or assets or the Company's securities since
the date of this Agreement.

          (c)    No litigation or administrative proceeding shall have been

otherwise prohibit or restrict the consummation of the transactions contemplated
by this Agreement or (ii) if adversely determined, would have a Material Adverse
Effect or have a material adverse effect on the Company's assets or upon its
securities.

                                      -15-
<PAGE>
          (d)  The Company shall have delivered to the Placement Agent a
certificate of its principal executive and financial officers as to the matters
set forth in Sections 8(a), (b) and (c) of this Agreement and to the further
effect that (i) the Company is not in default, in any respect, under any note,
loan agreement, security agreement, mortgage, deed of trust, indenture,
contract, alliance agreement, lease, license, joint venture agreement, agreement
or other instrument to which it is a party; (ii) the Company's representations
and warranties contained in this Agreement are true and correct in all respects
on such date with the same force and effect as if made on such date; (iii) there
has been no amendment or changes to the Company's charter or by-laws or
authorizing resolutions from those delivered pursuant to Section 8(a) of this
Agreement; and (iv) no event has occurred which, with or without the lapse of
time or giving of notice, or both, would constitute a breach or default thereof
by the Company or would cause acceleration of any obligation of the Company, or
could adversely affect the business, operations or financial condition of the
company.

          (e)   The Placement Agent shall have received the opinion of Miller &
Holguin, counsel for the Company, dated as of the closing date in form and
substance reasonably satisfactory to the Placement Agent and its counsel.

          (f)   The Company shall have prepared and filed or delivered to
counsel for filing with the SEC and any states in which such filing is required,
a Form D relating to the sale of the Common Stock and such other documents and
certificates as are required.

          (g)   Subscriptions for at least the Minimum Amount of Common Stock
shall have been accepted by the Company.

          (h)   In addition to the right of the Placement Agent to terminate
this Agreement and not consummate the transactions contemplated by this
Agreement as a result of the failure of the Company to comply with any of its
obligations set forth in this Agreement, this Agreement may be terminated by the
Placement Agent by written notice to the Company at any time prior to the
Initial Closing if, in the Placement Agent's sole judgment, (i) the Company
shall have sustained a loss that is material to the Company, whether or not
insured, by reason of fire, earthquake, flood, accident or other calamity, or
from any labor dispute or court or government action, order or decree; (ii)
trading in securities on any exchange or system shall have been suspended or
limited either generally or specifically with respect to the Common Stock; (iii)
material governmental restrictions have been imposed on trading in securities

declared by Federal or New York State authorities; (v) an outbreak of major
international hostilities or other national or international calamity shall have
occurred; (vi) the Congress of the United States or any state legislative body
shall have passed or taken any action or measure, or such bodies or any
governmental body or any authoritative accounting institute, or board, or any
governmental executive shall have adopted any orders, rules or regulations,
which the Placement Agent reasonably believes is likely to have a material
adverse effect on the business, financial condition or financial statements of
the Company or the market for the Common Stock; (vii) the Common Stock shall
have been delisted from Nasdaq; or (viii) there shall have been, in the
Placement Agent's judgment, a

                                      -16-
<PAGE>

material decline in the Dow Jones Industrial Index or the market price of the
Common Stock at any time subsequent to the date of this Agreement.

     9. Covenants of the Company.
        ------------------------

        (a) The Company agrees at all times as long as the Placement Agent
Warrants may be exercised, to keep reserved from the authorized and unissued
Common Stock, such number of shares of Common Stock as may be, from time to
time, issuable upon exercise the Placement Agent Warrants.

        (b) Within ninety (90) days of the Final Closing Date, the Company will
use its reasonable best efforts to raise an additional $3,000,000 in the
aggregate by closing on the sale of convertible securities on terms mutually
acceptable to the Company and Placement Agent (the "Additional Offering");
provided, however, that if the Company obtains additional financing of at least
$3,000,000 during such ninety (90) day period from an institution, including,
without limitation, a bank, insurance company or leasing company, the Company
will not be required to use its reasonable best efforts to close on the
Additional Offering. The Company shall, prior to the first closing of any such
sale of convertible securities, provide written notice to all holders of the
Common Stock sold pursuant to the Memorandum. Such notice shall include a
description of the proposed transaction and all documents relating thereto and
shall afford each holder of such Common Stock the right to participate in such
transaction by exchanging all of the shares of such Common Stock purchased by
the holder for such convertible securities. Each holder of such Common Stock
shall have fifteen (15) days after receiving notice from the Company to deliver
written notice to the Company (together with the original Common Stock and such
other documents as the Company shall reasonably request) that such holder
desires to participate in such transaction. Any holder desiring to participate
must do so as to all but not less than all of the Purchase Price paid for such
Common Stock. After receipt by the Company of the holder's notice to
participate, the Company will promptly deliver to such holder the convertible
securities against surrender by the holder of all shares of such Common Stock.

     10. Fees.
         ----

         (a)  Upon the receipt by the Company of the payments from the
Purchasers, the Company shall pay to the Placement Agent a fee equal to seven
(7%) percent of the gross proceeds from the Common Stock sold pursuant to this
Agreement. In addition, the Company shall issue at the Final Closing, five (5)
year warrants to purchase an amount of Common Stock equal to seven (7%) of the
number of shares of Common Stock sold pursuant to the Memorandum, at an exercise
price per share of 137.5% of the Purchase Price, subject to adjustment (the
"Placement Agent Warrants"), a portion or all of which may be allotted by the
Placement Agent to employees of the Placement Agent. The persons in whose name
the Placement Agent Warrants are issued shall all be "accredited investors" as
defined in the regulations promulgated under the 1933 Act and such persons shall
acquire such warrants for investment purposes only and not with a view towards
the redistribution thereof. The Company shall reimburse the Placement Agent for
up to $25,000 of its

                                      -17-
<PAGE>

reasonable costs and expenses, which amount includes the reasonable fees and
expenses of counsel to the Placement Agent, if and when a closing occurs.

          (b)      The Company shall pay any fees required in connection with
the qualification of the sale of the Common Stock under the state securities or
blue sky laws of any state which the Placement Agent reasonably deems necessary
and any other out-of-pocket expenses incurred by the Company in connection with
the transaction contemplated by this Agreement.

          (c)      All payments in connection with the sale of the Common Stock
shall be made pursuant to the terms and conditions of the Escrow Agreement dated
as of June 22, 2000 between Placement Agent and American Stock Transfer & Trust
Company, an executed copy of which has been delivered to and acknowledged by the
Company.

     11.  Notices. All notices provided for in this Agreement shall be in
          -------
writing signed by the party giving such notice, and delivered personally or sent
by overnight courier or messenger against receipt thereof or sent by registered
or certified mail, return receipt requested, or by facsimile transmission, if
confirmed by mail as provided in this Section 11. Notices shall be deemed to
have been received on the date of personal delivery or facsimile or, if sent by
certified or registered mail, return receipt requested, shall be deemed to be
delivered on the third business day after the date of mailing. Notices shall be
sent to the following addresses:
