         WHEREAS, Stockholders are the owner of all of the issued and
outstanding stock of SMI, which consists of One Hundred Thousand (100,000)
shares of common stock, .01 par value in the name of Robert Pratt and,

         WHEREAS, ETC desires to acquire eighty (80) percent of the issued and

         NOW THEREFORE, in consideration of the mutual promises herein contained
and for other good and valuable consideration, the parties hereto agree as
follows:

         1. Plan of Reorganization: The parties hereto intend that this

         2. Exchange of Shares Pratt: ETC and the Stockholder Robert Pratt agree
that eighty (80) percent of the One Hundred Thousand (100,000) shares of common

issuance by ETC to Stockholder of a certain number of shares of ETC's common
voting stock, par value $0.001 per share. The number of ETC shares to be issued
to Stockholder shall be determined by the following:

              (a) The value of the Shares being exchanged from the Stockholder
is $2,000,000. The SMI shares to be exchanged shall be delivered to ETC,
properly endorsed for transfer, on the Closing Date as the same is hereinafter

three years. Should the Company merge with another company and exchange ETC
stock the Stockholder will exchange for free trading shares.

              (d) If for any reason the common stock is not trading for one ($1)
dollars bid at the time the restrictive legend is removed, ETC will issue
additional free trading shares to make up the difference in the bid to a one
($1) dollar per share value.

notify ETC by certified mail of the United States Post Office and demand a full

exchanged for the eighty (80) percent of SMI. This right of recision will
automatically cancel any and all shares transferred to ETC from SMI and will
automatically cancel any and all shares transferred to SMI from ETC.

Shares are being offered and sold, the Warrants are being issued, and the
Warrant Shares are being offered, in each case to it in reliance on specific
exemptions from the registration requirements of United States federal and state
securities laws and that the Company is relying upon the truth and accuracy of,
and the Buyer's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of the Buyer set forth herein in order to
determine the availability of such exemptions and the eligibility of the Buyer
to acquire the Common Shares and the Warrants and to receive an offer of the

                  (e) INFORMATION PROVIDED. The Buyer and its advisors, if any,
have been furnished with all materials relating to the business, finances and
operations of the Company and materials relating to the offer and sale of the
Common Shares and the issuance of the Warrants and the offer of the Warrant

and the Buyer understands that its investment in the Shares involves a high
degree of risk;

                  (f) ABSENCE OF APPROVALS. The Buyer understands that no United
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Shares; and

                  (g) SUBSCRIPTION AGREEMENT. This Agreement has been duly and
validly authorized, executed and delivered on behalf of the Buyer and is a valid
and binding agreement of the Buyer enforceable in accordance with its terms,
subject as to enforceability to general principles of equity and to bankruptcy,
insolvency, moratorium and other similar laws affecting the enforcement of
creditors' rights generally.

                  3.  COMPANY REPRESENTATIONS, WARRANTIES, ETC.

                  The Company represents and warrants to, and covenants and
agrees with, the Buyer that:

                  (a) ORGANIZATION AND AUTHORITY. Each of the Company and its
subsidiaries listed on SCHEDULE 3(a)-1 attached hereto (the "Subsidiaries") is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation, and has all requisite corporate power and
authority to (i) own, lease and operate its properties and to carry on its
business as now being conducted, and (ii) to execute, deliver and perform its
obligations under this Agreement, the Warrants, the Registration Rights
Agreement, the form of which is attached hereto as ANNEX IV (the "Registration
Rights Agreement"), and the other agreements to be executed and delivered by the
Company in connection herewith, and to consummate the transactions contemplated
hereby and thereby. Each of the Company and the Subsidiaries is duly qualified
to do business as a foreign corporation and is in good standing in all
jurisdictions wherein such qualification is necessary and where failure so to
qualify could have a material adverse effect on the business, properties,
operations, condition (financial or other), results of operations or prospects
of the Company and the Subsidiaries, taken as a whole (a "Company Material
Adverse Effect"). The Company has no subsidiaries or equity investment in any
person other than the Subsidiaries.

                  (b) CAPITALIZATION. The authorized capital stock of the
Company consists of (a) 100,000,000 shares of Common Stock of which 18,807,926
shares were outstanding on November 30, 1999, all of which are fully paid and
nonassessable; and (b) 750,000 shares of Preferred Stock, $.001 par value, of
which 9,600 shares are designated as Series B Convertible

                                       3
<PAGE>   7

Preferred Stock and none of which are outstanding; and on the Closing Date there
will be (x) no material increase from November 30, 1999 in the number of shares
of Common Stock outstanding and (y) no issuances of preferred stock or other
equity securities other than Common Stock will have occurred since November 30,
1999. No shares of the Company's former Series A Preferred Stock, $.001 par
value, are outstanding and such series was retired on April 30, 1998. As of
November 30, 1999, the Company had outstanding options, warrants and similar
rights entitling the holders to purchase 1,890,833 shares of Common Stock. Other
than as set forth in the preceding sentence, the Company does not have
outstanding any material amount of securities (or obligations to issue any such
securities) convertible into, exchangeable for or otherwise entitling the
holders thereof to acquire shares of Common Stock, except as disclosed in the
SEC Reports. The Company has duly reserved from its authorized and unissued
shares of Common Stock the full number of shares required for (a) all options,
warrants, convertible securities and other rights to acquire shares of Common
Stock which are outstanding and (b) all shares of Common Stock and options and
other rights to acquire shares of Common Stock which may be issued or granted
under the stock option and similar plans which have been adopted by the Company
or any of the Subsidiaries. No antidilution or similar adjustments will occur by
reason of the issuance of the Common Shares or the issuance or exercise of the
Warrants or the issuance of the shares of Common Stock and the issuance or
exercise of the warrants to be issued pursuant to the other subscription
agreement for the purchase of shares of Common Stock and the acquisition of
common stock purchase warrants being entered into in connection herewith (the
"Other Subscription Agreement"). The outstanding shares of Common Stock and
outstanding options, warrants and other securities convertible into,
exchangeable for or otherwise entitling the holder thereof to acquire shares of
Common Stock have been duly authorized and validly issued. None of such
outstanding shares of Common Stock, options, warrants and other securities has
been issued in violation of the preemptive rights of any securityholder of the
Company. The offers and sales of the outstanding shares of Common Stock and such
options, warrants and other securities were at all relevant times either
registered under the 1933 Act and applicable state securities laws or exempt
from such requirements. No holder of any of the Company's securities has any
rights, "demand," "piggy-back" or otherwise, to have such securities registered
by reason of the intention to file, filing or effectiveness of the Registration
Statement (as defined in the Registration Rights Agreement).

                  (c) CONCERNING THE SHARES AND THE COMMON STOCK. The Shares
have been duly authorized. The Common Shares, when issued and paid for in
accordance with this Agreement and the Warrant Shares, when issued upon exercise
of the Warrants, will be duly and validly issued, fully paid and non-assessable
and will not subject the holder thereof to personal liability by reason of being
such holder. There are no preemptive or similar rights of any stockholder of the
Company or any other person to acquire any of the Shares. The Company has duly
reserved 1,500,000 shares of Common Stock for issuance as Common Shares and for
exercise of the Warrants and for the shares of Common Stock and warrants
issuable in connection with the Other Subscription Agreement, and such shares
shall remain so reserved, and the Company shall from time to time reserve such
additional shares of Common Stock as shall be required to be reserved pursuant
to the Warrants, as long as the Warrants are exercisable. The Common Stock is
listed for trading on the Nasdaq National Market ("Nasdaq") and (1) the Company
and the Common Stock meet the criteria for continued listing and trading on
Nasdaq; (2) the Company has not been notified since January 1, 1998 by Nasdaq or
the Nasdaq SmallCap Market ("Nasdaq SmallCap") of any failure or potential
failure to meet the criteria for continued listing and trading thereon and (3)
no suspension of trading in the Common Stock is in effect. The Company knows of
no reason that the Shares will not be eligible for listing on Nasdaq.

This Agreement, the Registration Rights Agreement and the Warrants and the other
agreements and instruments contemplated hereby and thereby have been duly and
validly authorized by the Company, this Agreement has been duly executed and

delivered by the Company, will be, valid and binding obligations of the Company
enforceable in accordance with their respective terms, subject as to
enforceability to general principles of equity and to bankruptcy, insolvency,
moratorium and other similar laws affecting the enforcement of creditors' rights
generally.

                  (e) NON-CONTRAVENTION. The execution and delivery by the
Company of this Agreement and the other documents contemplated by this Agreement
and the consummation by the Company of the issuance of the Common Shares and the
Warrants as contemplated by this Agreement, and the other transactions
contemplated by this Agreement, the Registration Rights Agreement and the
Warrants do not and will not, with or without the giving of notice or the lapse
of time, or both (i) result in any violation of any terms of the Certificate of
Incorporation, as amended, or By-laws of the Company or any Subsidiary, (ii)
conflict with or result in a breach by the Company or any Subsidiary of any of
the terms or provisions of, or constitute a default under, or result in the
modification, amendment, termination or cancellation of, result in the
acceleration of any obligation of the Company or any Subsidiary under, or result
in the creation or imposition of any lien, security interest, charge or
encumbrance upon any of the properties or assets of the Company or any
Subsidiary pursuant to, any indenture, mortgage, deed of trust or other
agreement or instrument to which the Company or any Subsidiary is a party or by
which the Company or any Subsidiary or any of their respective properties or
assets is bound or affected, (iii) violate or contravene any applicable law,
rule or regulation or any applicable decree, judgment or order of any court,
United States federal or state regulatory body, administrative agency or other
governmental body having jurisdiction over the Company or any Subsidiary or any
of their respective properties or assets or (iv) have any Company Material
Adverse Effect on any permit, certification, registration, approval, consent,
license or franchise necessary for the Company or any Subsidiary to own or lease
and operate any of their respective properties or to conduct any of their
respective businesses or the ability of the Company or any Subsidiary to make
use thereof.

                  (f) APPROVALS. No authorization, approval or consent of, or
filing with, any court, governmental body, regulatory agency, self-regulatory
organization, or stock exchange or market or the stockholders of the Company is
required to be obtained or made by the Company for (1) the execution, delivery
and performance by the Company of this Agreement, the Registration Rights
Agreement, the Warrants and the other agreements and instruments contemplated
hereby and thereby, (2) the issuance and sale of the Common Shares and the
issuance of the Warrants as contemplated by this Agreement and (3) the issuance
of Warrant Shares upon the exercise of the Warrants, other than (x) registration
of the resale of the Shares under the 1933 Act as contemplated by the
Registration Rights Agreement, (y) as may be required under applicable state
securities or "blue sky" laws and (z) filing of one or more Forms D with respect
to the Securities as required under Regulation D.

                  (g) INFORMATION PROVIDED. The information provided by or on
behalf of the Company to the Buyer in connection with the transactions
contemplated by this Agreement, including, without limitation, the information
referred to in Section 2(e) of this Agreement, does not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they are

                                       5
<PAGE>   9

made, not misleading, it being understood that, for purposes of this Section
3(g), any statement contained in such information shall be deemed to be modified
or superseded for purposes of this Section 3(g) to the extent that a statement
in any document included in such information which was prepared or filed with
the SEC on a later date modifies or replaces such statement, whether or not such
later prepared or filed statement so states. The Company has not filed any
reports with the SEC under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), since December 31, 1998 other than the SEC Reports.

                  (h) ABSENCE OF CERTAIN CHANGES. Since December 31, 1998, there
has been no change and no development which could have a Company Material
Adverse Effect, except as disclosed in the SEC Reports. Except as and to the
extent disclosed, reflected or reserved against in the financial statements of
the Company and the notes thereto included in the SEC Reports, neither the
Company nor any Subsidiary has any material (individually or in the aggregate)
liabilities, debts or obligations whether accrued, absolute, contingent or
otherwise, and whether due or to become due. Subsequent to December 31, 1998,
neither the Company nor any Subsidiary has incurred any liabilities, debts or
obligations of any nature whatsoever which are individually or in the aggregate
material to the Company and the Subsidiaries taken as a whole, other than those
incurred in the ordinary course of their respective businesses or disclosed in
the SEC Reports.

                  (i) ABSENCE OF CERTAIN PROCEEDINGS. Except as disclosed in the
SEC Reports, there is no action, suit, proceeding, inquiry or investigation
before or by any court, arbitrator, public board or body or governmental agency
(collectively, an "Action") pending or, to the knowledge of the Company or any
Subsidiary, threatened against the Company or any Subsidiary, in any such case
wherein an unfavorable decision, ruling or finding could have a Company Material
Adverse Effect or a material adverse effect on the transactions contemplated by
this Agreement or any of the documents contemplated hereby or which could
adversely affect the validity or enforceability of, or the authority or ability
of the Company to perform its obligations under, this Agreement or any of such
other documents; neither the Company or any Subsidiary nor any director or
officer thereof is or has been the subject of any Action involving a claim of
violation of or liability under federal or state securities laws or a claim of
breach of fiduciary duty; the Company does not have pending before the SEC any
request for confidential treatment of information and to the best of the
Company's knowledge no such request will be made by the Company prior to the
time the Registration Statement relating to the Shares which is contemplated by
the Registration Rights Agreement is first ordered effective by the SEC; and
there has not been, and to the best of the Company's knowledge there is not
pending or contemplated, any investigation by the SEC involving the Company or
any current or former director or officer of the Company.

                  (j) PROPERTIES. The Company and the Subsidiaries have good
title to or leasehold interests in all property real and personal (tangible and
intangible) and other assets owned by them, free and clear of all security
interests, charges, mortgages, liens or other encumbrances, except with respect
to capital lease obligations and protective filings by lessors and except such
as are described in the SEC Reports or such as do not materially interfere with
the use of such property made, or proposed to be made, by the Company or any
Subsidiary. The leases, licenses or other contracts or instruments under which
the Company and the Subsidiaries lease, hold or are entitled to use any
property, real or personal, are valid, subsisting and enforceable with only such
exceptions as do not materially interfere with the use of such property made, or
proposed to be made, by the Company or any Subsidiary. Neither the Company nor
any Subsidiary has received notice of any material violation of any applicable
law, ordinance, regulation, order or requirement relating to its owned or leased
properties. The

                                       6

Company does not have any knowledge of, and the Company has not given or
received any notice of, any pending conflicts with or infringement of the rights
of others with respect to any Company Proprietary Rights (as defined herein) or
with respect to any license of Company Proprietary Rights. No action, suit,
arbitration, or legal, administrative or other proceeding or investigation is
pending, or, to the best knowledge of the Company, threatened, which involves
any Company Proprietary Rights. Neither the Company nor any Subsidiary is
subject to any judgment, order, writ, injunction or decree of any court or any
federal, state, local, foreign or other governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign, or any
arbitrator, or has entered into or is a party to any contract which restricts or
impairs the use of any such Company Proprietary Rights in a manner which would
have a material adverse effect on the use by the Company or any Subsidiary of
any of the Company Proprietary Rights. To the best knowledge of the Company, no
Company Proprietary Rights and no services or products sold by the Company or
any Subsidiary, conflict with or infringe upon any proprietary rights available
to any third party. Neither the Company nor any Subsidiary has received written
notice of any pending conflict with or infringement upon such third-party
proprietary rights. Neither the Company nor any Subsidiary has entered into any
consent, indemnification, forbearance to sue or settlement agreement with
respect to Company Proprietary Rights other than in the ordinary course of
business. No claims have been asserted by any person with respect to the
validity of the Company's or any Subsidiary's ownership or right to use the
Company Proprietary Rights and, to the best knowledge of the Company, there is
no reasonable basis for any such claim to be successful. To the best knowledge
of the Company, the Company Proprietary Rights are valid and enforceable. No
registration relating to the Company Proprietary Rights has lapsed, expired or
been abandoned or canceled or is the subject of cancellation or other
adversarial proceedings, and all applications therefor are pending and are in
good standing, except for such lapses, expirations, abandonments, cancellations,
adversarial proceedings or failures to be in good standing which would not,
singly or in the aggregate, have a Company Material Adverse Effect. The Company
and the Subsidiaries have complied, in all material respects, with their
respective contractual obligations relating to the protection of the Company
Proprietary Rights used pursuant to licenses. To the best knowledge of the
Company, no person is infringing on or violating the Company Proprietary Rights.
As used herein, the term "Company Proprietary Rights" means all patents, patent
applications, inventions, trademarks, trade names, applications for registration
of trademarks, service marks, service mark applications, copyrights, know-how,
manufacturing processes, formulae, trade secrets, licenses and rights in any
thereof and any other intangible property and assets which are material to the
businesses of the Company and the Subsidiaries as now conducted, as proposed to
be conducted or as described in this Agreement.

                  (k) LABOR RELATIONS. No material labor problem exists or, to
the knowledge of the Company or any Subsidiary, is imminent with respect to any
of the employees of the Company or any Subsidiary.

                  (l) SEC FILINGS. The Company has timely filed all required
forms, reports and other documents required to be filed by the Company with the
SEC under the 1934 Act. All of such forms, reports and other documents complied,
when filed, in all material respects, with all applicable requirements of the
1933 Act and the 1934 Act.

                  (m) ABSENCE OF BROKERS, FINDERS, ETC. No broker, finder or
similar person is entitled to any commission, fee or other compensation by
reason of the transactions contemplated by this Agreement other than Wharton
Capital Partners Ltd. and an affiliated entity, and the Company shall pay, and
indemnify and hold harmless the Buyer from, any claim

                                       7
<PAGE>   11

made against the Buyer by such persons and any other person for any such
commission, fee or other compensation.

                  (n) NO SOLICITATION. No form of general solicitation or
general advertising was used by the Company or, to the best of its knowledge,
any other person acting on behalf of the Company, in respect of or in connection
with the offer and sale of the Securities. Neither the Company nor, to its
knowledge, any person acting on behalf of the Company has, either directly or
indirectly, sold or offered for sale to any person any of the Shares or the
Warrants or, within the six months prior to the date hereof, any other similar
security of the Company except as contemplated by this Agreement and the Other
Subscription Agreement; and neither the Company nor any person authorized to act
on its behalf will sell or offer for sale any shares of Common Stock or
Warrants, or solicit any offers to buy any shares of Preferred Stock or shares
of Common Stock or Warrants, so as thereby to cause the issuance or sale of any
of the Shares or the issuance of the Warrants to be in violation of Section 5 of
the 1933 Act.

                  (o) CERTAIN ISSUANCES OF SECURITIES. The Company has not
issued any shares of Common Stock or shares of any series of preferred stock or
other securities convertible into, exchangeable for or otherwise entitling the
holder to acquire shares of Common Stock which are subject to Rule 4460(i)(1)(D)
of Nasdaq as in effect from time to time or any successor, replacement or
similar provision thereof or of any other market on which the Common Stock is
listed for trading (the "Shareholder Approval Rule") and which would be
integrated with the sale of the Common Shares to the Buyer or the issuance of
Warrant Shares upon exercise of the Warrants for purposes of the Shareholder
Approval Rule.

                  (p) ABSENCE OF RIGHTS AGREEMENT. The Company has not adopted a
shareholder rights plan or similar arrangement relating to accumulations of
beneficial ownership of Common Stock or a change in control of the Company.

                  4.  CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

                  (a) TRANSFER RESTRICTIONS. (1) The Company and the Buyer
acknowledge and agree that (A) the Shares and the Warrants have not been and are
not being registered under the provisions of the 1933 Act and, except as
provided in the Registration Rights Agreement with respect to the resale of the
Shares, the Shares have not been and are not being registered for resale under
the 1933 Act, and the Securities may not be transferred unless (i) subsequently
registered for resale thereunder or (ii) the Buyer shall have delivered to the
Company an opinion of counsel, reasonably satisfactory in form, scope and
substance to the Company, to the effect that the Securities to be sold or
transferred may be sold or transferred pursuant to an exemption from such
registration; (B) any resale of the Securities made in reliance on Rule 144
promulgated under the 1933 Act ("Rule 144") may be made only in accordance with
the terms of Rule 144 and further, if Rule 144 is not applicable, any such
resale of Securities under circumstances in which the seller, or the person
through whom the sale is made, may be deemed to be an underwriter, as that term
is used in the 1933 Act, may require compliance with some other exemption under
the 1933 Act or the rules and regulations of the SEC thereunder; and (C) neither
the Company nor any other person is under any obligation to register the
Securities (other than pursuant to the Registration Rights Agreement) under the
1933 Act or to comply with the terms and conditions of any exemption thereunder
(other than pursuant to Section 4(d) hereof and pursuant to the Registration
Rights Agreement).

                  (2) In addition to the restrictions set forth in Section
4(a)(1), so long as the Company is in compliance in all material respects with
its obligations to the Buyer under this

                                       8
<PAGE>   12

Agreement, the Warrants and the Registration Rights Agreement, the Buyer may not
sell or transfer any Securities in a transaction other than pursuant to a
registration statement under the 1933 Act or pursuant to Rule 144 (a "Private
Transaction") without obtaining the prior approval of the Company of the
proposed transferee in such Private Transaction (the "Proposed Transferee") in
accordance with this Section 4(a)(2). At least ten Business Days prior to the
consummation of a Private Transaction, the Buyer shall notify the Company of the
identity of the Proposed Transferee and the amount of Securities proposed to be
transferred. If within eight Business Days after receiving such notice the
Company provides the Buyer with a certified copy of a resolution of the
Company's Board of Directors (a "Restricted Person Resolution") stating that the
Proposed Transferee is a Restricted Person (as defined herein), the Buyer may
not transfer any Securities to such Proposed Transferee without again seeking
the approval of the Company pursuant to this Section 4(a)(2). If the Company
notifies the Buyer of its approval of such Proposed Transferee or fails to
deliver a Restricted Person Resolution to the Buyer within such eight Business
Day period, the Company shall be deemed to have approved the Proposed Transferee
and shall thereupon cooperate with the Buyer to promptly consummate such Private
Transaction in accordance with this Agreement and Section 9 of the Registration
Rights Agreement. As used in this Agreement, "Restricted Person" means a
Proposed Transferee, as reasonably determined by the Board of Directors of the
Company, who has acquired, or is reasonably likely to attempt to acquire, shares
of Common Stock for the purpose of (i) seeking control of or seeking to
influence control of the Company or its Board of Directors, (ii) entering into
an unsolicited business combination transaction with the Company or (iii)
seeking to influence the management or policies of the Company.

                  (b) RESTRICTIVE LEGEND. (1) The Buyer acknowledges and agrees
that the Warrants shall bear a restrictive legend in substantially the following
form (and a stop-transfer order may be placed against transfer of the Warrants):

         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended. The securities have been
         acquired for investment and may not be resold, transferred or assigned
         in the absence of an effective registration statement for the
         securities under the Securities Act of 1933, as amended, or an opinion
         of counsel that registration is not required under said Act.

                  (2) The Buyer further acknowledges and agrees that until such
time as the Shares have been registered for resale under the 1933 Act as
contemplated by the Registration Rights Agreement, the certificates for the
Shares may bear a restrictive legend in substantially the following form (and a
stop-transfer order may be placed against transfer of the certificates for the
Shares):

         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended. The securities have been
         acquired for investment and may not be resold, transferred or assigned
         in the absence of an effective registration statement for the
         securities under the Securities Act of 1933, as amended, or an opinion
         of counsel that registration is not required under said Act.

                  (3) Once the Registration Statement required to be filed by
the Company pursuant to Section 2 of the Registration Rights Agreement has been
declared effective, thereafter (1) upon request of the Buyer the Company will
substitute certificates without restrictive legend for certificates for all
Shares issued prior to the date such Registration Statement is declared
effective by the SEC which bear such restrictive legend and remove any
stop-transfer restriction relating thereto promptly, but in no event later than
three Trading Days

                                       9
<PAGE>   13

(as defined herein) after surrender of such certificates by the Buyer and (2)
the Company shall not place any restrictive legend on certificates for Warrant
Shares or impose any stop-transfer restriction thereon. As used in this
Agreement, "Trading Day" means a day on whichever of (x) the national securities
exchange, (y) Nasdaq or (z) the Nasdaq SmallCap which at the time constitutes
the principal securities market for the Common Stock is open for general
trading.

                  (c) REGISTRATION RIGHTS AGREEMENT. The parties hereto agree to
enter into the Registration Rights Agreement in the form attached hereto as
ANNEX IV on or before the Closing Date.

                  (d) FORM D. The Company agrees to file a Form D with respect
to the Securities as required under Regulation D and to provide a copy thereof
to the Buyer promptly after such filing. The Buyer agrees to cooperate with the
Company in connection with such filing and, upon request of the Company, to
provide all information relating to the Buyer reasonably required for such
filing.

                  (e) AUTHORIZATION FOR TRADING; REPORTING STATUS. On or before
the Closing Date, the Company shall file a notification for listing of
additional shares with the Nasdaq relating to the Shares and shall provide
evidence of such filing to the Buyer. So long as the Buyer beneficially owns any
of the Shares or the Warrants, the Company shall file all reports required to be
filed with the SEC pursuant to Section 13 or 15(d) of the 1934 Act and the
Company shall not terminate its status as an issuer required to file reports
under the 1934 Act even if the 1934 Act or the rules and regulations thereunder
would permit such termination.

                  (f) USE OF PROCEEDS. Neither the Company nor any Subsidiary
owns or has any present intention of acquiring any "margin stock" as defined in
Regulation G (12 CFR Part 207) of the Board of Governors of the Federal Reserve
System ("margin stock"). The proceeds of sale of the Shares will be used for
general working capital purposes and in the operation of the Company's business.
None of such proceeds will be used, directly or indirectly (1) to make any loan
to or investment in any other person (other than financing the Company's
subsidiaries in the ordinary course of business or in connection with an
acquisition of another corporation or business or assets of another corporation
or business) or (2) for the purpose, whether immediate, incidental or ultimate,
of purchasing or carrying any margin stock or for the purpose of maintaining,
reducing or retiring any indebtedness which was originally incurred to purchase
or carry any stock that is currently a margin stock or for any other purpose
which might constitute the transactions contemplated by this Agreement a
"purpose credit" within the meaning of such Regulation G. Neither the Company
nor any agent acting on its behalf has taken or will take any action which might
cause this Agreement or the transactions contemplated hereby to violate
Regulation G, Regulation T or any other regulation of the Board of Governors of
the Federal Reserve System or to violate the 1934 Act, in each case as in effect
now or as the same may hereafter be in effect.

                  (g) BLUE SKY LAWS. On or before the Closing Date, the Company
shall take such action as shall be necessary to qualify, or to obtain an
exemption for, the Common Shares for sale to the Buyer and the Warrants for
issuance to the Buyer pursuant to this Agreement and the Warrant Shares for
issuance to the Buyer upon exercise of the Warrants under such of the securities
or "blue sky" laws of jurisdictions as shall be applicable to the sale of the
Common Shares and the issuance of the Warrants pursuant to this Agreement and
the issuance to the Buyer of Warrant Shares upon exercise of the Warrants. The
Company shall furnish copies of all filings, applications, orders and grants or
confirmations of exemptions relating to such securities or "blue sky" laws on or
prior to the Closing Date.

                                       10

                  (h) CERTAIN EXPENSES. If the closing occurs, the Company shall
pay or reimburse the Buyer for all reasonable expenses (including, without
limitation, legal fees and expenses of counsel to the Buyer and the Buyer's due
diligence expenses) not in excess of $30,000 incurred by the Buyer in connection
with this Agreement and the transactions contemplated hereby and the buyer under
the Other Subscription Agreement. In addition, the Company or the Buyer, as the
case may be, shall pay on demand all expenses incurred by the other party,
including reasonable attorneys' fees and expenses, as a consequence of, or in
connection with (1) the negotiation, preparation or execution of any amendment,
modification or waiver of this Agreement, the Registration Rights Agreement, the
Warrants and the other agreements and instruments contemplated hereby and
thereby requested by the requesting party, (2) any default or breach of any of
the defaulting or breaching party's obligations set forth in any of such
agreements or instruments and (3) the enforcement or restructuring of any right
of, including the collection of any payments due, the other party under any of
such agreements or instruments, including any action or proceeding relating to
such enforcement, or any order, injunction or other process seeking to restrain
a party from paying any amount due the other party, in which the other party
prevails.

                  (i) CERTAIN ISSUANCES OF SECURITIES. (1) Unless the Company
obtains the approval of its stockholders as required by the Shareholder Approval
Rule or a waiver thereof from Nasdaq, the Company will not issue any shares of
Common Stock or shares of any series of preferred stock or other securities
convertible into, exchangeable for, or otherwise entitling the holder to
acquire, shares of Common Stock which would be subject to the requirements of
the Shareholder Approval Rule and which would be integrated with the sale of the
Common Shares and issuance of the Warrants to the Buyer or the issuance of
Warrant Shares upon exercise of the Warrants for purposes of the Shareholder
Approval Rule.

                  (2) During the period from the date of this Agreement to the
date on which the Registration Statement shall have been effective with the SEC
for 180 consecutive days, the Company shall not offer, sell, contract to sell or
issue (or engage any person to assist the Company in taking any such action) (A)
any security (whether debt or equity) containing terms relating to the number of
shares issuable and the purchase price therefor which are similar to the terms
of the Class B Warrants or (B) any equity securities or securities convertible
into, exchangeable for or otherwise entitling the holder to acquire, any Common
Stock at a price below the market price of the Common Stock on the date of such
issuance (or below an average market price for a reasonable period prior to such
issuance) or the date of conversion, exchange or other exercise thereof,
including, without limitation, any combination of different types of securities
where the aggregate purchase price paid or payable for all securities is less
than the aggregate market value of such securities and, in the case of warrants
and similar securities, taking into account reasonable assumptions regarding
valuation using the Black-Scholes model and similar techniques (collectively,
"Equity Securities"); provided, however, that nothing in this Section 4(i)(2)
shall prohibit the Company from issuing securities (w) pursuant to compensation
plans for employees, directors, officers, advisers or consultants of the Company
and in accordance with the terms of such plans as in effect as of the date of
this Agreement, (x) upon exercise of conversion, exchange, purchase or similar
rights issued, granted or given by the Company and outstanding as of the date of
this Agreement and disclosed in the SEC Reports or this Agreement, (y) pursuant
to a public offering underwritten on a firm commitment basis registered under
the 1933 Act or (z) as part of a transaction involving a strategic alliance,
acquisition of stock or assets, merger, collaboration, joint venture,
partnership or other similar arrangement of the Company with another
corporation, partnership or other business entity which is engaged in a business
similar to or related to the business of the Company, so long as

                                       11
<PAGE>   15

in the case of this clause (z) the Board of Directors by resolution duly adopted
(and a copy of which shall be furnished to the Buyer promptly after adoption)
determines that such issuance is fair to the holders of each class and series of
capital stock of the Company and to the Buyer in respect of its equity interest
in the Company that is represented by the Shares and the Warrants.

                  (3) Subject to the restrictions in Section 4(i)(1), during the
period from the date of execution and delivery of this Agreement to the date
which is one year after the Closing Date, the Company shall not offer, sell,
contract to sell or issue (or engage any person to assist the Company in taking
any such action) any Equity Securities without giving the Buyer the first right
to acquire the Equity Securities on the same terms as the Equity Securities are
to be offered to other investors; provided, however, that this Section 4(i)(3)
shall not apply to the offer or sale of Equity Securities by the Company in the
transactions, and subject to the conditions, set forth in clauses (w), (x), (y)
and (z) of the proviso to the first sentence of Section 4(i)(2) above. The
Company shall give notice to the Buyer of the detailed terms of the Equity
Securities proposed to be issued and, promptly after requested by the Buyer,
such other information as requested by the Buyer to the extent such information
is reasonably available to the Company. The Buyer may, by notice to the Company,
exercise such right of first refusal at any time until the later of (x) ten
Business Days after such notice from the Company to the Buyer and (y) one
Business Day after the Company provides such additional information as shall
have been requested by the Buyer during such ten Business Day period.

                  (j) CERTAIN TRADING RESTRICTIONS. The Buyer agrees that on the
Closing Date it will have no short position in the Common Stock. The Buyer
agrees on its behalf and on behalf of its affiliates that on and after the
Closing Date it will not engage in any short sales or other hedging transactions
relating to the Common Stock so long as the Company does not intentionally or
negligently fail to comply in all material respects with its obligations to the
Buyer under this Agreement, the Warrants and the Registration Rights Agreement
which failure results in a material adverse effect on the Buyer's ability to
timely sell Shares as contemplated by this Agreement and, in the event of any
noncompliance with such obligations, such noncompliance is cured within ten
Business Days of the Company's receipt of notice thereof from the Buyer.

                  (k) MONTHLY REPORTS. Within five Business Days after the end
of each calendar month commencing December 1999 to and including the month in
which the Buyer sells or transfers all remaining Common Shares, the Buyer shall
give notice to the Company of the number of Common Shares held by the Buyer as
of the close of business on the last day of each such month.

                  (l) BEST EFFORTS. Each of the parties shall use its best
efforts timely to satisfy each of the conditions to the other party's
obligations to sell and purchase the Common Shares set forth in Section 7 or 8,
as the case may be, of this Agreement on or before the Closing Date.

                  5.  REPURCHASE AT OPTION OF THE COMPANY.

                  If (i) the Company shall be in compliance in all material
respects with its obligations to the Buyer (including, without limitation, its
obligations under this Agreement, the Warrants and the Registration Rights
Agreement), (ii) on the date the Repurchase Notice (as defined herein) is given
and at all times until the Repurchase Date (as defined herein), the Registration
Statement is effective and available for use by the Buyer for the resale of its
Shares and (iii) on the date the Repurchase Notice is given and on the
Repurchase Date, the Company has available and unrestricted Cash and Cash
Equivalent Balances not less than the aggregate

                                       12
<PAGE>   16

amount to be paid to repurchase shares of Common Stock pursuant to Section 5 of
this Agreement and the Other Subscription Agreement, then the Company shall have
the right to repurchase outstanding Common Shares and Warrant Shares issued upon
exercise of the Class B Warrants held by the Buyer (collectively, "Outstanding
Shares") as follows:

                  (a) REPURCHASE RIGHT. If the Company gives a Repurchase Notice
to the Buyer not less than ten Trading Days or more than 30 Trading Days prior
to the Repurchase Date, the Company may at any time repurchase all or from time
to time any part of the Outstanding Shares held on the Repurchase Date which are
subject to such Repurchase Notice in accordance with this Section 5. On the
Repurchase Date, the Company shall make payment to the Buyer of the applicable
Repurchase Price (as defined herein) multiplied by the number of Outstanding
Shares to be repurchased in immediately available funds to such account as
specified by the Buyer in writing to the Company at least one Trading Day prior
to the Repurchase Date. Notwithstanding anything to the contrary in this Section
5, prior to the Repurchase Date or such later date on which the Repurchase Price
is paid, the Buyer shall be free to sell or otherwise transfer any Outstanding
Shares which are subject to the Repurchase Notice with respect to such
Repurchase Date.

                  (b) CERTAIN DEFINITIONS. As used in this Agreement, the
following terms shall have the following meanings:

                  "Cash and Cash Equivalent Balances" of any person on any date
shall be determined from such person's books maintained in accordance with
Generally Accepted Accounting Principles, and means, without duplication, the
sum of (1) the cash accrued by such person and its subsidiaries on a
consolidated basis on such date and available for use by such person and its
subsidiaries on such date and (2) all assets which would, on a consolidated
balance sheet of such person and its subsidiaries prepared as of such date in
accordance with Generally Accepted Accounting Principles, be classified as cash
or cash equivalents, less the amount thereof which secures any outstanding
indebtedness of the Company or its Subsidiaries.

                  "Generally Accepted Accounting Principles" for any person
means the generally accepted accounting principles and practices applied by such
person from time to time in the preparation of its audited financial statements.

                  "Market Price" shall have the meaning provided in the Class B
Warrants.

                  "Repurchase Date" means the date of repurchase of Outstanding
Shares pursuant to Section 5.

                  "Repurchase Notice" means a notice given by the Company to the
Buyer pursuant to Section 5 exercising the Company's right to repurchase all or
a portion of the Outstanding Shares pursuant to Section 5 which states (1) the
number of Outstanding Shares which are to be repurchased, (2) the Repurchase
Price and the formula for determining the same, determined in accordance
herewith and (3) the applicable Repurchase Date.

                  "Repurchase Price" means, for each Outstanding Share
repurchased pursuant to Section 5, 120% of the greater of: (x) the arithmetic
average of the Market Price on each of the five consecutive Trading Days prior
to the date the Repurchase Notice is given to the Buyer, (y) the arithmetic
average of the Market Price on each of the five consecutive Trading Days prior
to the Repurchase Date and (z) if determined prior to 180 days after the Closing
Date, the price

                                       13
<PAGE>   17

per share paid by the Buyer for the Common Shares on the Closing
Date or, if determined on or after the day which is 180 days after the Closing
Date, the most recent Adjustment Price (as defined in the Class B Warrants).

                  6.  CLOSING DATE.

                  Subject to the satisfaction or waiver of the conditions set
forth in Sections 7 and 8, the date and time of the issuance and sale of the
Common Shares and the issuance of the Warrants (the "Closing Date") shall be
