The Merger Agreement is attached hereto as Exhibit 10.1 and incorporated herein by reference for all purposes. Stock Purchase Agreements. On June 10, 1996, RESI and H. Wayne Huizenga entered into a Stock Purchase Agreement (the "Huizenga Purchase Agreement"), which provides for Huizenga to purchase from Republic, for an aggregate purchase price of $5,250,000, (i) an aggregate of 2,000,000 shares of Common Stock (the "Huizenga Shares"), and (ii) warrants to purchase an additional (a) 2,000,000 shares of Common Stock at $2.625 per share, (b) 2,000,000 shares of Common Stock at $3.125 per share, and (c) 2,000,000 shares of Common Stock at $3.875 per share (collectively, the "Huizenga Warrants"), on the terms set forth in the 2 3 Huizenga Purchase Agreement and subject to obtaining stockholder and certain regulatory approvals, including the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 ("HSR Act"), and other customary closing conditions.

The MGD Purchase Agreement is attached hereto as Exhibit 10.3 and incorporated herein by reference for all purposes. Mr. DeGroote is presently Republic's Chairman, Chief Executive Officer, President and the beneficial owner of approximately 49.7% RESI Common Stock. The transactions contemplated by the Merger Agreement and the Purchase Agreements may be collectively referred to herein as the "Combination." Upon consummation of the Combination, Alliance will be the largest stockholder of RESI and may effectively control the management and operations of RESI. The following is a description of certain changes that will occur with respect to RESI upon consummation of the Combination. Change In Security Ownership Of Republic. Currently, Mr. DeGroote beneficially owns 5,536,000 shares of RESI Common Stock (through MGD Holdings) representing approximately 49.7% of the outstanding shares of RESI Common Stock. Upon consummation of the Combination and assuming the exercise of all of the Warrants in full at such time (but not the exercise of any other outstanding options or warrants), and giving effect to the issuance of the Merger Shares, the Huizenga Shares and the MGD Shares, Alliance and Mr. DeGroote will beneficially own approximately 41.7% and 29.5%, respectively, of the outstanding shares of RESI Common Stock. In addition, contemporaneously with the consummation of the Combination, MGD Holdings will enter into a voting agreement with Alliance (the "Voting Agreement") pursuant to which MGD Holdings, for a period of two years commencing as of the date thereof, will agree to vote all shares of RESI Common Stock held by it from time to time in accordance with the recommendation of the management of Alliance. Accordingly, upon execution of the Voting Agreement, Alliance will have the ability to control the outcome of matters submitted to vote of the RESI stockholders, including the election of directors. 3 4 Change In The Composition Of The Republic Board Of Directors. In connection with the Combination, the Board of Directors will be enlarged to seven members, one present member of the Board of Directors, Michael J. Occhionero, will resign, and Messrs. Edward F. Feighan, Craig L. Stout and Harve A. Ferrill will be nominated by Alliance and elected to the RESI Board of Directors and Mr. Richard C. Rochon will be nominated by Alliance upon the recommendation of Mr. Huizenga and elected to the RESI Board of Directors. Mr. Joseph E. LoConti, currently a director of RESI, is the Chairman of the Board, President and controlling shareholder of Alliance. After consummation of the Combination, Mr. LoConti will continue to serve as a director of RESI and will also serve as Vice Chairman of the RESI Board of Directors. Consequently, Messrs. LoConti, Feighan, Stout and Ferrill, if they vote together, will have the ability to control most actions submitted to a vote of the RESI Board of Directors. ITEM 7.

                                  ARTICLE VIII
 
                                INDEMNIFICATION
 
     8.1 INDEMNIFICATION GENERALLY. RESI on the one hand, and Alliance, on the
other hand (each an Indemnifying Party as defined below), shall indemnify the
other as follows:
 
          (a) Alliance will defend, indemnify and hold RESI harmless in respect
     of the aggregate of all indemnifiable damages of RESI. For this purpose,
     "indemnifiable damages" of RESI means the aggregate of all expenses,
     losses, costs, deficiencies, liabilities and damages (including related
     counsel fees and expenses) incurred or suffered by RESI resulting from (i)
     any inaccurate representation or warranty made by Alliance or the Alliance
     Companies, or pursuant to, this Agreement or (ii) any material default in
     the performance of any of the covenants or agreements made by Alliance or
     the Alliance Companies in this Agreement. Notwithstanding the foregoing,
     Alliance shall only be liable for indemnification to RESI under this
     Article IX to the extent the aggregate amount of the "indemnifiable
     damages" of RESI exceeds $500,000.
 
          (b) RESI will defend, indemnify and hold Alliance harmless in respect
     of all indemnifiable damages of Alliance. For this purpose, "indemnifiable
     damages" of Alliance means the aggregate of all expenses, losses, costs,
     deficiencies, liabilities and damages (including related counsel fees and
     expenses) incurred or suffered by Alliance resulting from (i) from any
     inaccurate representation or warranty made by RESI or the Merger Subs in,
     or pursuant to, this Agreement; or (ii) any default in the performance of
     any of the covenants or agreements made by RESI or the Merger Subs in this
     Agreement.
 
     8.2 INDEMNIFICATION PROCEDURES. Each Person entitled to indemnification
under this Section (an "Indemnified Party") shall give notice as promptly as
reasonably practicable to each party required to provide indemnification under
this Article VIII (an "Indemnifying Party") of any action commenced against or
by it in respect of which indemnity may be sought hereunder, but failure to so
notify an Indemnifying Party shall not relieve such Indemnifying Party from any
liability that it may have otherwise than on account of this Article VIII so
long as such failure shall not have materially prejudiced the position of the
Indemnifying Party. Upon such notification, the Indemnifying Party shall assume
the defense of such action if it is a claim brought by a third party. If and
after such assumption, the Indemnifying Party shall not be entitled to
reimbursement of any expenses incurred by it in connection with such action
except as described below. In any such action, any Indemnified Party shall have
the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party unless (i) the Indemnifying
Party and the Indemnified Party shall have mutually agreed to the contrary or
(ii) the named parties in any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing or conflicting interests between them. The Indemnifying
Party shall not be liable for any settlement of any proceeding effected without
its written consent (which shall not be unreasonably withheld or delayed by such
Indemnifying Party), but if settled with such consent or if there be final
judgment for the plaintiff, the Indemnifying Party shall indemnify the
Indemnified Party from and against any loss, damage or liability by reason of
such settlement or judgment.
 
     8.3 SURVIVAL. The indemnification obligations of RESI and Alliance set
forth in this Article VIII shall survive through the period beginning on the
Closing Date and ending on April 1, 1998.

                       TERMINATION, AMENDMENT AND WAIVER
 
     9.1 TERMINATION. This Agreement may be terminated, and the transactions
contemplated hereby may be abandoned at any time prior to the Effective Time, as
follows:
 
          (a) by written agreement of the Parties;
 
          (b) by RESI or Alliance if the transactions contemplated by this
     Agreement have not been consummated on or before September 30, 1996;
     provided, however, that the right to terminate this Agreement shall not be
     available to a Party whose failure to fulfill any obligation under this
     Agreement has been the cause, or resulted in, the failure of the Effective
     Time to occur on or before such date;
 
          (c) by RESI, upon a breach of any representation, warranty, covenant
     or agreement on the part of Alliance or the Alliance Companies set forth in
     this Agreement, or if any representation or warranty of Alliance or the
     Alliance Companies shall have become untrue, in either case such that the
     conditions set forth in Section 7.2 would not be satisfied and would have a
     Material Adverse Effect on RESI (a "Terminating Alliance Breach");
     provided, however, that if such Terminating Alliance Breach is cured by
     Alliance or the Alliance Companies, as the case may be, within 60 calendar
     days after notice thereof through the continuous exercise of its best
     efforts, then RESI may not terminate this Agreement under this Section
     9.1(c); or
 
          (d) by Alliance, upon a breach of any representation, warranty,
     covenant or agreement on the part of RESI or the Merger Subs set forth in
     this Agreement, or if any representation or warranty of RESI or the Merger
     Subs shall have become untrue, in either case such that the conditions set
     forth in Section 7.3 would not be satisfied and would have a Material
     Adverse Effect on Alliance (a "Terminating RESI Breach"); provided,
     however, that if such Terminating RESI Breach is cured by RESI or the
     Merger Subs as the case may be, within 60 calendar days after notice
     thereof through the continuous exercise of its best efforts then, Alliance
     may not terminate this Agreement under this Section 9.1(d).
 
     9.2 EFFECT OF TERMINATION.
 
          (a) If this Agreement is validly terminated pursuant to Section 9.1
     hereof, this Agreement will terminate and no Party hereto will have any
     liability to the other Parties hereto except that any such termination
     shall be without prejudice to any claim which either Party may have against
     the other for breach of this Agreement (or any representations, warranty,
     covenant, or agreement included herein).
 
          (b) All reasonable out-of-pocket expenses incurred in connection with
     this Agreement and the transactions contemplated hereby by a nonbreaching

     10.3 REMEDIES.
 
          (a) Each Party acknowledges that the other Parties would not have an
     adequate remedy at law for money damages in the event that any of the
     covenants or agreements in this Agreement of such Party was not performed
     in accordance with its terms, and it is therefore agreed that each Party in
     addition to and without limiting any other remedy or right any Party may
     have, shall have the right to an injunction or other equitable relief in
     any court of competent jurisdiction, enjoining any such breach and
     enforcing specifically the terms and provisions hereof, and each Party
     hereby waives any and all defenses it may have on the ground of lack of
     jurisdiction or competence of the court to grant such an injunction or
     other equitable relief.
 
          (b) All rights, powers and remedies under this Agreement or otherwise
     available in respect hereof at law or in equity shall be cumulative and not
     alternative, and the exercise or beginning of the exercise of any thereof
     by any Party shall not preclude the simultaneous or later exercise of any
     other such right, power or remedy by any Party.
 
     10.4 ENTIRE AGREEMENT. This Agreement (including the exhibits and schedules
attached hereto) and other documents delivered at the Closing pursuant hereto,

all of the Parties. No failure to exercise, and no delay in exercising, any
right, power or privilege under this Agreement shall operate as a waiver, nor
shall any single or partial exercise of any right, power or privilege hereunder

breach of any provision shall be deemed to be a waiver of any preceding or
succeeding breach of the same or any other provisions, nor shall any waiver be
implied from any course of dealing between the Parties. No extension of time for
performance of any obligations or other acts hereunder or under any other
agreement shall be deemed to be an extension of the time for performance of any

equity, that they may have against each other.

     10.11 SEVERABILITY. The Parties stipulate that the terms and provisions of
this Agreement are fair and reasonable as of the date of this Agreement.
However, if any provision of this Agreement shall be determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions of this Agreement shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated. Moreover, if any of such provisions shall for any reason be
determined by a court of competent jurisdiction to be unenforceable because it
is deemed to be excessively broad or vague as to duration, geographical scope,
activity or subject, such provision shall be construed by limiting, reducing or
defining it, so as to be unenforceable.

        provided, however, that the right to terminate this Agreement shall not
        be available to a Party whose failure to fulfill any obligation under

        Investor Breach"); provided, however, that if such Terminating Investor
        Breach is cured by Investor within 60 calendar days after notice thereof

        that if such Terminating Issuer Breach is cured by Issuer within 60
        calendar days after notice thereof through the continuous exercise of
        its best efforts, then Investor may not terminate this Agreement under
        this Section 2.2(a)(iv).
 
          (b) Effect of Termination.
 
             (i) If this Agreement is validly terminated pursuant to Section
        2.2(a) hereof, this Agreement will terminate and no Party hereto will
        have any liability to the other Parties hereto except that any such
        termination shall be without prejudice to any claim which either Party
        may have against the other for breach of this Agreement (or any
        representations, warranty, covenant, or agreement included herein).
 
             (ii) All reasonable out-of-pocket expenses incurred in connection
        with this Agreement and the transactions contemplated hereby by a
        nonbreaching Party who terminates this Agreement pursuant to Section

                    REPRESENTATIONS AND WARRANTIES OF ISSUER
 
     As a material inducement to Investor entering into this Agreement and
purchasing the Shares and Warrants, Issuer represents and warrants to Investor
as follows:
 
     3.1 CORPORATE STATUS. Issuer is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware. Issuer
has all requisite corporate power and authority to own or lease, as the case may
be, its properties and to carry on its business as now conducted. Issuer and its
Subsidiaries are qualified or licensed to conduct business in all jurisdictions
where its or their ownership or lease of property and the conduct of its or
their business requires such qualification or licensing, except to the extent
that failure to so qualify or be licensed would not have a Material Adverse
Effect on Issuer. There is no pending or threatened proceeding for the
dissolution, liquidation or insolvency of Issuer or any of its Subsidiaries.
 
     3.2 CORPORATE POWER AND AUTHORITY. Issuer has the corporate power and
authority to execute and deliver this Agreement and to perform its obligations
hereunder and consummate the transactions contemplated hereby. Issuer has taken
all necessary corporate action to authorize the execution, delivery and
performance of this Agreement and the transactions contemplated hereby.
 
     3.3 ENFORCEABILITY. This Agreement has been duly executed and delivered by
Issuer and constitutes a legal, valid and binding obligation of Issuer,
enforceable against Issuer in accordance with its terms, except as the same may
be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally and
general equitable principles regardless of whether such enforceability is
considered in a proceeding at law or in equity.
 
     3.4 NO VIOLATION. The execution and delivery by Issuer of this Agreement
and the Warrant Certificates, the consummation of the transactions contemplated
hereby or thereby, and the compliance by Issuer with the terms and provisions
hereof or thereof, will not (a) result in a violation or breach of, or
constitute, with or without due notice or lapse of time or both, a material
default (or give rise to any right of termination, cancellation or acceleration)
under, any of the terms, conditions or provisions of any Contract to which
Issuer is a party or by which Issuer or any material portion of Issuer's
properties or assets may be bound, (b) violate any Requirement of Law applicable
to Issuer or any material portion of Issuer's properties or assets or (c) result
in the imposition of any Lien upon any of the properties or assets of Issuer;
except where any of the foregoing would not have a Material Adverse Affect on
Issuer.
 
     3.5 CONSENTS/APPROVALS. No consent, approval, waiver or other action by any
Person under any Contract to which either Issuer or any of its Subsidiaries is a
party, or by which any of their respective properties or assets are bound, is
required or necessary for the execution, delivery or performance by Issuer of
this Agreement and the consummation of the transactions contemplated hereby,
except (a) as required under the Hart-Scott-Rodino Antitrust Improvements Act of
1976 as amended and the rules and regulations promulgated thereunder (the "HSR
Act"), (b) as required by the Securities Act, the Exchange Act and state
securities or "blue sky" laws, (c) as required by the Delaware General
Corporation Law (the "DGCL") and (d) where the failure to obtain such consents,
filings, authorizations, approvals or waivers or make such filings would not
prevent or delay the consummation of the transactions contemplated by this
Agreement or otherwise prevent Issuer from performing its obligations hereunder.
 
     3.6 CAPITALIZATION. The authorized capital stock of Issuer consists of
20,000,000 shares of Common Stock. As of the date hereof, after giving effect to
the Stock Split, 10,809,638 shares of Common Stock are validly issued and
outstanding, fully paid and non-assessable. Except (a) for 493,800 shares of
Common Stock, after giving effect to the Stock Split, reserved for issuance
pursuant to certain options or warrants issued pursuant to Issuer's 1995 Stock
Option Plan, (b) as contemplated by this Agreement, the Merger Agreement and the
MGD Purchase Agreement (defined herein) and (c) in connection with the
distribution of Issuer's Common Stock to holders of Republic Waste Industries,
Inc. common stock in April 1995, there are (y) no rights, options, warrants,
convertible securities, subscription rights or other agreements, calls, plans,
contracts or commitments of any kind relating to the issued and unissued capital
stock of, or other equity interest in, Issuer outstanding or authorized and (z)
no contractual obligations of Issuer to repurchase, redeem or

                   REPRESENTATIONS AND WARRANTIES OF INVESTOR
 
     As a material inducement to Issuer entering into this Agreement and issuing
the Shares and Warrants, Investor represents and warrants to Issuer as follows:
 
     4.1 POWER AND AUTHORITY. Investor is an individual residing in the State of
Florida with competence and authority under applicable law to execute and
deliver, and to perform his obligations under, this Agreement and consummate the
transactions contemplated hereby, and has all necessary authority to execute,
deliver and perform this Agreement and the transactions contemplated hereby.
 
     4.2 NO VIOLATION. The execution and delivery by Investor of this Agreement
and the consummation of the transactions contemplated hereby, and the compliance
by Investor with the terms and provisions hereof, will not (a) result in a
violation or breach of, or constitute, with or without due notice or lapse of
time or both, a material default (or give rise to any right of termination,
cancellation or acceleration) under any of the terms, conditions or provisions
of any Contract to which Investor is a party or by which Investor or any
material portion of Investor's properties or assets may be bound, (b) violate
any Requirement of Law applicable to Investor or any material portion of
Investor's properties or assets or (d) result in the imposition of any Lien upon
any of the properties or assets of Investor; except where any of the foregoing
would not have a Material Adverse Affect on Investor.
 
     4.3 CONSENTS/APPROVALS. No consent, approval, waiver or other action by any
Person under any Contract to which Investor is a party, or by which any of
Investor's respective properties or assets are bound, is required or necessary
for the execution, delivery or performance by Investor of this Agreement and the
consummation of the transactions contemplated hereby, except (a) as required
under the HSR Act, (b) as required by the Securities Act, the Exchange Act and
state securities or "blue sky" laws, (c) as required by the DGCL and (d) where
the failure to obtain such consents, filings, authorizations, approvals or
waivers or make such flings would not prevent or delay the consummation of the
transactions contemplated by this Agreement or otherwise prevent Investor from
performing Investor's obligations hereunder or have a Material Adverse Effect on
Investor.
 
     4.4 ENFORCEABILITY. This Agreement has been duly executed and delivered by
Investor and constitutes a legal, valid and binding obligation of Investor,
enforceable against Investor in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditor's rights generally and general equitable principles regardless of
whether enforceability is considered in a proceeding at law or in equity.
 
     4.5 INVESTMENT INTENT. Investor is acquiring the Shares and Warrants
hereunder for Investor's own account and with no present intention of
distributing or selling the Shares or any interest in the Warrants or the
Warrant Shares in violation of the Securities Act or any applicable state
securities law. Investor agrees that Investor will not sell or otherwise dispose
of any of the Shares or any interest in the Warrants or Warrant Shares unless
such sale or other disposition has been registered or qualified (as applicable)
under the Securities Act and applicable state securities laws or, in the opinion
of Investors' counsel delivered to Issuer (which opinion shall be reasonably
satisfactory to Issuer) such sale or other disposition is exempt from such
registration or qualification (as applicable). Investor understands that the
sale of the Shares and Warrants acquired by Investor hereunder and any issuance
of Warrants Shares have not been registered under the Securities Act but are
issued through transactions exempt from the registration and prospectus delivery
requirements of Section 4(2) of the Securities Act, and that the reliance of
Issuer on such exemption from registration is predicated in part on these
representations and warranties of Investor. Investor acknowledges that pursuant
to Section 1.2 a restrictive legend consistent with the foregoing has been or
will be placed on the certificates representing the Shares, the Warrant
Certificates and on certificates representing any Warrant Shares until such
legend is permitted to be removed under appropriate law.
 
     4.6 INVESTOR KNOWLEDGE. Investor is an accredited investor as such term is
defined in Rule 501 of the General Rules and Regulations under the Securities
Act, and has such knowledge and experience in financial and business matters
that he is capable of evaluating the merits and risks of the investment to be
made by him

hereunder. Investor acknowledges that no representations or warranties of any
type or description have been made to Investor by any Person with regard to
Issuer or any of its Subsidiaries, or any of their respective businesses,
properties or prospects or the investment contemplated herein, other than the
representations and warranties set forth in Article III hereof.
 
     4.7 NO COMMISSIONS. Investor has not incurred any obligation for any
finder's or broker's or agent's fees or commissions in connection with the
purchase of the Shares and Warrants.

                              REGISTRATION RIGHTS
 
     Investor shall have the following registration rights with respect to the
Registrable Securities owned by him:
 
     7.1 TRANSFER OF REGISTRATION RIGHTS. Investor may assign the registration
rights with respect to the Shares and the Warrant Shares to any party or parties
to which he may from time to time transfer the Shares or Warrant Shares. Upon
assignment of any registration rights pursuant to this Section 7.1, Investor
shall deliver to Issuer a notice of such assignment which includes the identity
and address of any assignee (collectively, Investor and each such subsequent
holder is referred to as a "Holder").
 
     7.2 REQUIRED REGISTRATION. As promptly as practicable after the Closing,
Issuer agrees to register all of the Shares and all of the Warrant Shares
pursuant to a registration statement on Form S-3 (the "Shelf Registration
Statement"). Issuer shall use its best efforts to cause the Shelf Registration
Statement to be declared effective as quickly as practicable and to maintain the
effectiveness of the Shelf Registration Statement until such time as Issuer
reasonably determines based on an opinion of counsel that the Holders
will be eligible to sell all of the Shares then owned by the Holders without the
need for continued registration of the Shares in the three-month period
immediately following the termination of the effectiveness of the Shelf
Registration Statement. Issuer's obligations contained in this Section 7.2 shall
terminate on the second anniversary of the earlier of (i) the expiration of the
Series C Warrants or (ii) the date on which all of the Warrants have been
exercised.

     7.3 REGISTRATION PROCEDURES.
 
          (a) In case of each registration, qualification or compliance effected
     by Issuer subject to this Article VII, Issuer shall keep Holder advised in
     writing as to the initiation of each such registration, qualification and
     compliance and as to the completion thereof. In addition, Issuer shall at
     its own expense:
 
             (i) subject to this Section 7.3, before filing a registration or
        prospectus or any amendment or supplements thereto, furnish to counsel
        selected by Holder copies of all such documents proposed to be filed and
        the portions of such documents provided in writing by Holder for use
        therein, subject to such Holder's approval, and for which Holder shall
        indemnify Issuer;
 
             (ii) prepare and file with the SEC such amendments and supplements
        to the Shelf Registration Statement as may be necessary to keep the
        Shelf Registration Statement effective and comply with provisions of the
        Securities Act with respect to the disposition of all securities covered
        thereby during such period;
 
             (iii) update, correct, amend and supplement the Shelf Registration
        Statement as necessary;
 
             (iv) if such offering is to be underwritten, in whole or in part,
        enter into a written agreement in form and substance reasonably
        satisfactory to the managing underwriter and the registering Holder;
 
             (v) furnish to Holder such number of prospectuses, including
        preliminary prospectuses, and other documents that are included in the
        Shelf Registration Statement as Holder may reasonably request from time
        to time;
 
             (vi) use its best efforts to register or qualify such Registrable
        Securities under such other securities or blue sky laws of such
        jurisdictions of the United States as Holder may request to enable it to
        consummate the disposition in such jurisdiction of the Registrable
        Securities (provided that Issuer will not be required to (A) qualify
        generally to do business in any jurisdiction where it would not
        otherwise be required to qualify but for this Article VII, or (B)
        consent to general service of process in any such jurisdiction);
 
             (vii) notify Holder, at any time when the prospectus included in
        the Shelf Registration Statement relating to the Registrable Securities
        is required to be delivered under the Securities Act, of the happening
        of any event which would cause such prospectus to contain an untrue
        statement of a material fact or omit any fact necessary to make the
        statement therein in light of the circumstances under which they are
        made not misleading and, at the request of Holder, prepare a supplement
        or amendment to such prospectus, so that, as thereafter delivered to
        purchasers of such shares, such prospectus will not contain any untrue
        statements of a material fact or omit to state any fact necessary to
        make the statements therein in light of the circumstances under which
        they are made not misleading;
 
             (viii) use its best efforts to cause all such Registrable
        Securities to be listed on each securities exchange on which similar
        securities issued by Issuer are then listed and obtain all necessary
        approvals from the NASD for trading thereon;
 
             (ix) provide a transfer agent and registrar for all such
        Registrable Securities not later than the effective date of the Shelf
        Registration Statement;
 
             (x) upon the sale of any Registrable Securities pursuant to the
        Shelf Registration Statement, remove all restrictive legends from all
        certificates or other instruments evidencing such Registrable Securities
        (to the extent permitted by the Securities Act);
 
             (xi) furnish at the request of Holder, on the date that the
        Registrable Securities are delivered to the underwriter for sale in
        connection with a registration pursuant to this Section 7.3, if such
        Registrable Securities are being sold through an underwriter, or if such
        Registrable Securities are not being sold through an underwriter, on the
        date that the Shelf Registration Statement becomes effective, an opinion
        dated as of such date of the counsel representing Issuer for purposes of
 
                                       12
   13
 
        registration, in form and substance as is customarily given to
        underwriters in an underwritten public offering, addressed to such
        underwriter, if any and to Holder; and
 
             (xii) make available for inspection by Holder, any underwriter
        participating in any disposition pursuant to such registration
        statement, and any attorney, accountant or any other agent retained by
        Holder or such underwriter, all financial and other records, pertinent
        corporate documents and properties of Issuer, and cause Issuer's
        officers, directors and employees to supply all information reasonably
        requested by any such Holder, underwriter, attorney, accountant or agent
        in connection with the Shelf Registration.
 
          (b) Except as required by law, all expenses incurred by Issuer in
     complying with this Article VII, including but not limited to, all
     registration, qualification and filing fees, printing expenses, fees and
     disbursements of counsel and accountants for Issuer, blue sky fees and
     expenses (including fees and disbursements of counsel related to all blue
     sky matters) ("Registration Expenses") incurred in connection with any
     registration, qualification or compliance pursuant this Article VII shall
     be borne by Issuer. All underwriting discounts and selling commissions
     applicable to a sale incurred in connection with any registration of
     Registrable Securities and the legal fees of Holder shall be borne by
     Holder.
 
     7.4 FURTHER INFORMATION. If Registrable Securities owned by Holder are
included in any registration, such Holder shall use reasonable efforts to
cooperate with Issuer and shall furnish Issuer such information regarding itself
as Issuer may reasonably request and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.
 
                                  ARTICLE VIII
 
                                INDEMNIFICATION
 
     8.1 INDEMNIFICATION GENERALLY. Issuer, on the one hand, and Investor, on
the other hand (each an Indemnifying Party as defined below), shall indemnify
the other from and against any and all losses, damages, liabilities, claims,
charges, actions, proceedings, demands, judgments, settlement costs and expenses
of any nature whatsoever (including, without limitation, attorneys' fees and
expenses) or deficiencies resulting from any breach of a representation,
warranty or covenant by the Indemnifying Party and all claims, charges, actions
or proceedings incident to or arising out of the foregoing.
 
     8.2 INDEMNIFICATION RELATING TO REGISTRATION RIGHTS.
 
          (a) With respect to any registration, qualification or compliance
     effected or to be effected pursuant to Article VII of this Agreement,
     Issuer shall indemnify each Holder of Registrable Securities whose
     securities are included or are to be included therein, each of such
     Holder's directors and officers, each underwriter (as defined in the
     Securities Act) of the securities sold by such Holder, and each Person who
     controls (within the meaning of the Securities Act) any such Holder or
     underwriter (a "Controlling Person") from and against all losses, damages,
     liabilities, claims, charges, actions, proceedings, demands, judgments,
     settlement costs and expenses of any nature whatsoever (including, without
     limitation, attorneys' fees and expenses) or deficiencies of any such
     Holder or any such underwriter or Controlling Person concerning:
 
             (i) any untrue statement (or alleged untrue statement) of a
        material fact contained in any prospectus, offering circular or other
        document (including any related registration statement, notification or
        the like) incident to any such registration, qualification or
        compliance;
 
             (ii) any omission (or alleged omission) to state therein a material
        fact required to be stated therein or necessary to make the statement
        therein, in the light of the circumstances under which it was made, not
        misleading; or
 
             (iii) any violation by Issuer of the Securities Act or any rule or
        regulation promulgated thereunder applicable to Issuer, or of any blue
        sky or other state securities laws or any rule or regulation promulgated
        thereunder applicable to Issuer,
 
                                       13
   14
 
     in each case, relating to any action or inaction required of Issuer in
     connection with any such registration, qualification or compliance, and
     subject to Section 8.3 below will reimburse each such Person entitled to
     indemnity under this Section 8.2 for all legal and other expenses
     reasonably incurred in connection with investigating or defending any such
     loss, damage, liability, claim, charge, action, proceeding, demand,
     judgment, settlement or deficiency; provided, however, the foregoing
     indemnity and reimbursement obligation shall not be applicable to the
     extent that any such matter arises out of or is based on any untrue
     statement (or alleged untrue statement) or omission (or alleged omission)
     made in reliance upon and in conformity with written information furnished
     to Issuer by or on behalf of such Holder specifically for use in such
     prospectus, offering circular or other document.
 
          (b) With respect to any registration, qualification or compliance
     effected or to be effected pursuant to this Agreement, each Holder of
     Registrable Securities whose securities are included or are to be included
     therein, shall indemnify Issuer from and against all losses, damages,
     liabilities, claims, charges, actions, proceedings, demands, judgments,
     settlement costs and expenses of any nature whatsoever (including, without
     limitation, attorneys' fees and expenses) or deficiencies of Issuer
     concerning:
 
             (i) any untrue statement (or alleged untrue statement) of a
        material fact contained in any prospectus, offering circular or other
        document (including any related registration statement, notification or
        the like) incident to any such registration, qualification or
        compliance;
 
             (ii) any omission (or alleged omission) to state therein a material
        fact required to be stated therein or necessary to make the statement
        therein, in the light of the circumstances under which it was made, not
        misleading; or
 
             (iii) any violation by such Holder of the Securities Act or any
        rule or regulation promulgated thereunder applicable to Issuer or such
        Holder or of any blue sky or other state securities laws or any rule or
        regulation promulgated thereunder applicable to Issuer or such Holder,
 
     in each case, relating to any action or inaction required of such Holder in
     connection with any such registration, qualification or compliance, and
     subject to Section 8.3 below will reimburse Issuer for all legal and other
     expenses reasonably incurred in connection with investigating or defending
     any such loss, damage, liability, claim, charge, action, proceeding,
     demand, judgment, settlement or deficiency; provided, however, the
     foregoing indemnity and reimbursement obligation shall only be applicable
     to the extent that any such matter arises out of or is based on any untrue
     statement (or alleged untrue statement) or omission (or alleged omission)
     made in reliance upon and in conformity with written information furnished
     to Issuer by or on behalf of Holder specifically for use in such
     prospectus, offering circular or other document; provided further, the
     obligations of Holder hereunder shall be limited to an amount equal to the
     proceeds to Holder of Registrable Securities sold as contemplated
     hereunder.
 
     8.3 INDEMNIFICATION PROCEDURES. Each Person entitled to indemnification
under this Section (an "Indemnified Party") shall give notice as promptly as
reasonably practicable to each party required to provide indemnification under
this Section (an "Indemnifying Party") of any action commenced against or by it
in respect of which indemnity may be sought hereunder, but failure to so notify
an Indemnifying Party shall not relieve such Indemnifying Party from any
liability that it may have otherwise than on account of this indemnity agreement
so long as such failure shall not have materially prejudiced the position of the
Indemnifying Party. Upon such notification, the Indemnifying Party shall assume
the defense of such action if it is a claim brought by a third party, and after
such assumption the Indemnifying Party shall not be entitled to reimbursement of
any expenses incurred by it in connection with such action except as described
below. In any such action, any Indemnified Party shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the contrary or (ii) the named
parties in any such action (including any impleaded parties) include both the
Indemnifying Party and the Indemnified Party and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
or conflicting interests between them. The Indemnifying Party shall not be
liable for any settlement of any proceeding effected without its written consent
(which shall not be unreasonably withheld or delayed by such
 
                                       14
   15
 
Indemnifying Party), but if settled with such consent or if there be final
judgment for the plaintiff, the Indemnifying Party shall indemnify the
Indemnified Party from and against any loss, damage or liability by reason of
such settlement or judgment.
 
                                   ARTICLE IX

     10.2 SURVIVAL. Notwithstanding any knowledge of facts determined or
determinable by Investor by investigation, Investor shall have the right to
fully rely on the representations, warranties, covenants and agreements of
Issuer contained in this Agreement or in any other documents or papers delivered
in connection herewith. Each representation, warranty, covenant and agreement of
the parties set forth in this Agreement is independent of each other
representation, warranty, covenant and agreement. Each representation and

     10.3 REMEDIES.
 
          (a) Each of Investor and Issuer acknowledge that the other Party would
     not have an adequate remedy at law for money damages in the event that any
     of the covenants or agreements of such Party in this Agreement was not
     performed in accordance with its terms, and it is therefore agreed that
     each of Investor and Issuer in addition to and without limiting any other
     remedy or right such Party may have, shall have the right to an injunction
     or other equitable relief in any court of competent jurisdiction, enjoining
     any such breach and enforcing specifically the terms and provisions hereof,
     and each of Investor and Issuer hereby waive any and all defenses such
     Party may have on the ground of lack of jurisdiction or competence of the
     court to grant such an injunction or other equitable relief.
 
          (b) All rights, powers and remedies under this Agreement or otherwise
     available in respect hereof at law or in equity shall be cumulative and not
     alternative, and the exercise or beginning of the exercise of any thereof
     by any Party shall not preclude the simultaneous or later exercise of any
     other such right, power or remedy by such Party.
 
     10.4 OTHER REGISTRATION RIGHTS. Issuer shall not grant to any third party
any registration rights more favorable than any of those contained herein, so
long as any of the registration rights under this Agreement remain in effect,
unless the Holders of Registrable Securities are granted rights to participate
together with any such third party in such registration rights.
 
     10.5 ENTIRE AGREEMENT. This Agreement (including the exhibits and schedules
attached hereto) and other documents delivered at the Closing pursuant hereto,
contain the entire understanding of the Parties in respect of the subject matter
hereof and supersede all prior agreements and understandings between or among

                              REGISTRATION RIGHTS

Registrable Securities owned by him:
 
     7.1 TRANSFER OF REGISTRATION RIGHTS. Investor may assign the registration
rights with respect to the Shares and the Warrant Shares to any party or parties
to which he may from time to time transfer the Shares or Warrant Shares. Upon
assignment of any registration rights pursuant to this Section 7.1, Investor
shall deliver to Issuer a notice of such assignment which includes the identity
and address of any assignee (collectively, Investor and each such subsequent
holder is referred to as a "Holder").
 
     7.2 REQUIRED REGISTRATION. As promptly as practicable after the Closing,
Issuer agrees to register all of the Shares and all of the Warrant Shares
pursuant to a registration statement on Form S-3 (the "Shelf Registration
Statement"). Issuer shall use its best efforts to cause the Shelf Registration
Statement to be declared effective as quickly as practicable and to maintain the
effectiveness of the Shelf Registration Statement until such time as Issuer
reasonably determines based on an opinion of counsel that the Holders will be
eligible to sell all of the Shares then owned by the Holders without the need
for continued registration of the Shares in the three-month period immediately
following the termination of the effectiveness of the Shelf Registration
Statement. Issuer's obligations contained in this Section 7.2 shall terminate on
the second anniversary of the earlier of (i) the expiration of the Series C
Warrants or (ii) the date on which all of the Warrants have been exercised.
 
     7.3 REGISTRATION PROCEDURES.
 
          (a) In case of each registration, qualification or compliance effected
     by Issuer subject to this Article VII, Issuer shall keep Holder advised in
     writing as to the initiation of each such registration, qualification and
     compliance and as to the completion thereof. In addition, Issuer shall at
     its own expense:
 
             (i) subject to this Section 7.3, before filing a registration or
        prospectus or any amendment or supplements thereto, furnish to counsel
        selected by Holder copies of all such documents proposed to be filed and
        the portions of such documents provided in writing by Holder for use
        therein, subject to such Holder's approval, and for which Holder shall
        indemnify Issuer;
 
             (ii) prepare and file with the SEC such amendments and supplements
        to the Shelf Registration Statement as may be necessary to keep the
        Shelf Registration Statement effective and comply with provisions of the
        Securities Act with respect to the disposition of all securities covered
        thereby during such period;
 
             (iii) update, correct, amend and supplement the Shelf Registration
        Statement as necessary;
 
             (iv) if such offering is to be underwritten, in whole or in part,
        enter into a written agreement in form and substance reasonably
        satisfactory to the managing underwriter and the registering Holder;
 
             (v) furnish to Holder such number of prospectuses, including
        preliminary prospectuses, and other documents that are included in the
        Shelf Registration Statement as Holder may reasonably request from time
        to time;
 
             (vi) use its best efforts to register or qualify such Registrable
        Securities under such other securities or blue sky laws of such
        jurisdictions of the United States as Holder may request to enable it to
        consummate the disposition in such jurisdiction of the Registrable
        Securities (provided that Issuer will not be required to (A) qualify
        generally to do business in any jurisdiction where it would not
        otherwise be required to qualify but for this Article VII, or (B)
        consent to general service of process in any such jurisdiction);
 
             (vii) notify Holder, at any time when the prospectus included in
        the Shelf Registration Statement relating to the Registrable Securities
        is required to be delivered under the Securities Act,
 
                                        9
   10
 
        of the happening of any event which would cause such prospectus to
        contain an untrue statement of a material fact or omit any fact
        necessary to make the statement therein in light of the circumstances
        under which they are made not misleading and, at the request of Holder,
        prepare a supplement or amendment to such prospectus, so that, as
        thereafter delivered to purchasers of such shares, such prospectus will
        not contain any untrue statements of a material fact or omit to state
        any fact necessary to make the statements therein in light of the
        circumstances under which they are made not misleading;
 
             (viii) use its best efforts to cause all such Registrable
        Securities to be listed on each securities exchange on which similar
        securities issued by Issuer are then listed and obtain all necessary
        approvals from the NASD for trading thereon;
 
             (ix) provide a transfer agent and registrar for all such
        Registrable Securities not later than the effective date of the Shelf
        Registration Statement;
 
             (x) upon the sale of any Registrable Securities pursuant to the
        Shelf Registration Statement, remove all restrictive legends from all
        certificates or other instruments evidencing such Registrable Securities
        (to the extent permitted by the Securities Act);
 
             (xi) furnish at the request of Holder, on the date that the
        Registrable Securities are delivered to the underwriter for sale in
        connection with a registration pursuant to this Section 7.3, if such
        Registrable Securities are being sold through an underwriter, or if such
        Registrable Securities are not being sold through an underwriter, on the
        date that the Shelf Registration Statement becomes effective, an opinion
        dated as of such date of the counsel representing Issuer for purposes of
        registration, in form and substance as is customarily given to
        underwriters in an underwritten public offering, addressed to such
        underwriter, if any and to Holder; and
 
             (xii) make available for inspection by Holder, any underwriter
        participating in any disposition pursuant to such registration
        statement, and any attorney, accountant or any other agent retained by
        Holder or such underwriter, all financial and other records, pertinent
        corporate documents and properties of Issuer, and cause Issuer's
        officers, directors and employees to supply all information reasonably
        requested by any such Holder, underwriter, attorney, accountant or agent
        in connection with the Shelf Registration.
 
          (b) Except as required by law, all expenses incurred by Issuer in
     complying with this Article VII, including but not limited to, all
     registration, qualification and filing fees, printing expenses, fees and
     disbursements of counsel and accountants for Issuer, blue sky fees and
     expenses (including fees and disbursements of counsel related to all blue
     sky matters) ("Registration Expenses") incurred in connection with any
     registration, qualification or compliance pursuant this Article VII shall
     be borne by Issuer. All underwriting discounts and selling commissions
     applicable to a sale incurred in connection with any registration of
     Registrable Securities and the legal fees of Holder shall be borne by
     Holder.
 
     7.4 FURTHER INFORMATION. If Registrable Securities owned by Holder are
included in any registration, such Holder shall use reasonable efforts to
cooperate with Issuer and shall furnish Issuer such information regarding itself
as Issuer may reasonably request and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.
 
                                  ARTICLE VIII
 
                                INDEMNIFICATION

        the like) incident to any such registration, qualification or
        compliance;
 
             (ii) any omission (or alleged omission) to state therein a material
        fact required to be stated therein or necessary to make the statement
        therein, in the light of the circumstances under which it was made, not
        misleading; or

     expenses reasonably incurred in connection with investigating or defending
     any such loss, damage, liability, claim, charge, action, proceeding,
     demand, judgment, settlement or deficiency; provided, however, the
     foregoing indemnity and reimbursement obligation shall only be applicable
     to the extent that any such matter arises out of or is based on any untrue
     statement (or alleged untrue
 
                                       11
   12
 
     statement) or omission (or alleged omission) made in reliance upon and in
     conformity with written information furnished to Issuer by or on behalf of
     Holder specifically for use in such prospectus, offering circular or other
     document; provided further, the obligations of Holder hereunder shall be
     limited to an amount equal to the proceeds to Holder of Registrable
     Securities sold as contemplated hereunder.
 
     8.3 INDEMNIFICATION PROCEDURES. Each Person entitled to indemnification
under this Section (an "Indemnified Party") shall give notice as promptly as
reasonably practicable to each party required to provide indemnification under
this Section (an "Indemnifying Party") of any action commenced against or by it
in respect of which indemnity may be sought hereunder, but failure to so notify
an Indemnifying Party shall not relieve such Indemnifying Party from any
liability that it may have otherwise than on account of this indemnity agreement
so long as such failure shall not have materially prejudiced the position of the
Indemnifying Party. Upon such notification, the Indemnifying Party shall assume
the defense of such action if it is a claim brought by a third party, and after
such assumption the Indemnifying Party shall not be entitled to reimbursement of
any expenses incurred by it in connection with such action except as described
below. In any such action, any Indemnified Party shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the contrary or (ii) the named
parties in any such action (including any impleaded parties) include both the
Indemnifying Party and the Indemnified Party and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
or conflicting interests between them. The Indemnifying Party shall not be
liable for any settlement of any proceeding effected without its written consent
(which shall not be unreasonably withheld or delayed by such Indemnifying
Party), but if settled with such consent or if there be final judgment for the
plaintiff, the Indemnifying Party shall indemnify the Indemnified Party from and
against any loss, damage or liability by reason of such settlement or judgment.

     10.2 SURVIVAL. Notwithstanding any knowledge of facts determined or
determinable by Investor by investigation, Investor shall have the right to
fully rely on the representations, warranties, covenants and agreements of
Issuer contained in this Agreement or in any other documents or papers delivered
in connection herewith. Each representation, warranty, covenant and agreement of
the parties set forth in this Agreement is independent of each other
representation, warranty, covenant and agreement. Each representation and
warranty made by any party in this Agreement shall survive the Closing through
the period ending on the date two years from the Closing Date.
 
     10.3 REMEDIES.
 
          (a) Each of Investor and Issuer acknowledge that the other Party would
     not have an adequate remedy at law for money damages in the event that any
     of the covenants or agreements of such Party in this Agreement was not
     performed in accordance with its terms, and it is therefore agreed that
     each of Investor and Issuer in addition to and without limiting any other
     remedy or right such Party may have, shall have the right to an injunction
     or other equitable relief in any court of competent jurisdiction, enjoining
     any such breach and enforcing specifically the terms and provisions hereof,
     and each of Investor and Issuer hereby waive any and all defenses such
     Party may have on the ground of lack of jurisdiction or competence of the
     court to grant such an injunction or other equitable relief.
 
          (b) All rights, powers and remedies under this Agreement or otherwise
     available in respect hereof at law or in equity shall be cumulative and not
     alternative, and the exercise or beginning of the exercise of any thereof
     by any Party shall not preclude the simultaneous or later exercise of any
     other such right, power or remedy by such Party.
 
     10.4 OTHER REGISTRATION RIGHTS. Issuer shall not grant to any third party
any registration rights more favorable than any of those contained herein, so
long as any of the registration rights under this Agreement remain in effect,
unless the Holders of Registrable Securities are granted rights to participate
together with any such third party in such registration rights.
 
     10.5 ENTIRE AGREEMENT. This Agreement (including the exhibits and schedules
attached hereto) and other documents delivered at the Closing pursuant hereto,
contain the entire understanding of the Parties in respect of the subject matter
hereof and supersede all prior agreements and understandings between or among
the Parties with respect to such subject matter. The exhibits and schedules
hereto constitute a part hereof as though set forth in full above.
 
     10.6 EXPENSES; TAXES. Except as otherwise provided in this Agreement, the
Parties shall pay their own fees and expenses, including their own counsel fees,
incurred in connection with this Agreement or any
 
                                       14
   15
 
transaction contemplated hereby. Any sales tax, stamp duty, deed transfer or
other tax (except taxes based on the income of Investor) arising out of the sale
of the Shares and Warrants by Issuer to Investor and issuance of Warrant Shares
upon exercise of the Warrants and consummation of the transactions contemplated
by this Agreement shall be paid by Issuer.
 
     10.7 AMENDMENT; WAIVER. This Agreement may not be modified, amended,
supplemented, canceled or discharged, except by written agreement executed by
all of the Parties. No failure to exercise, and no delay in exercising, any
right, power or privilege under this Agreement shall operate as a waiver, nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude the exercise of any other right, power or privilege. No waiver of any
breach of any provision shall be deemed to be a waiver of any preceding or
succeeding breach of the same or any other provision, nor shall any waiver be
implied from any course of dealing between the Parties. No extension of time for
performance of any obligations or other acts hereunder or under any other
agreement shall be deemed to be an extension of the time for performance of any
other obligations or any other acts. The rights and remedies of the Parties
under this Agreement are in addition to all other rights and remedies, at law or
equity, that they may have against each other.
 
     10.8 BINDING EFFECT; ASSIGNMENT. The rights and obligations of this
Agreement shall bind and inure to the benefit of the parties hereto and their
respective successors and legal assigns. The rights and obligations of this
Agreement may not be assigned by any party without the prior written consent of
the other party.
 
     10.9 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be an original but all of which together shall
constitute one and the same instrument.
 
     10.10 HEADING. The headings contained in this Agreement are for convenience
of reference only and are not to be given any legal effect and shall not affect
the meaning or interpretation of this Agreement.
 
     10.11 GOVERNING LAW; INTERPRETATION. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED FOR ALL PURPOSES BY THE LAWS OF THE STATE OF
DELAWARE APPLICABLE TO CONTRACTS EXECUTED AND TO BE WHOLLY PERFORMED WITHIN SUCH
STATE.
 
     10.12 SEVERABILITY. The parties stipulate that the terms and provisions of
this Agreement are fair and reasonable as of the date of this Agreement.
However, any provision of this Agreement shall be determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions of this Agreement shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated. If, moreover, any of those provisions shall for any reason be
determined by a court of competent jurisdiction to be unenforceable because
excessively broad or vague as to duration, geographical scope, activity or
subject, it shall be construed by limiting, reducing or defining it, so as to be
enforceable.
