                         AGREEMENT AND PLAN OF MERGER

     This Agreement and Plan of Merger (this "Agreement") is entered into as of
July 6, 2000 by and among Convergent Networks, Inc., a Delaware corporation (the
"Buyer"), Hemisphere Acquisition Corporation, a Florida corporation and a wholly
owned subsidiary of the Buyer (the "Transitory Subsidiary"), Hemisphere
Investments, Inc., a Florida corporation (the "Company"), and certain
shareholders of the Company listed on the signature pages hereto.  The Buyer,
the Transitory Subsidiary and the Company are referred to collectively herein as
the "Parties."

     This Agreement contemplates a merger of the Transitory Subsidiary into the
Company.  In such merger, the stockholders of the Company will receive common
stock of the Buyer in exchange for their capital stock of the Company.

     The respective Boards of Directors of the Buyer, the Transitory Subsidiary
and the Company have determined that it is advisable and in the best interests
of the respective corporations and their shareholders that the Transitory
Subsidiary be merged with and into the Company in accordance with the Florida
Corporation Act and the terms and conditions of this Agreement, pursuant to
which the Company will be the surviving corporation and will be a wholly owned
subsidiary of the Buyer.

     Now, therefore, in consideration of the representations, warranties and
covenants herein contained, the Parties agree as follows.

                                   ARTICLE I
                                  THE MERGER

     1.1  The Merger.  Upon and subject to the terms and conditions of this
          ----------
Agreement, the Transitory Subsidiary shall merge with and into the Company (with
such merger referred to herein as the "Merger") at the Effective Time (as
defined below).  From and after the Effective Time, the separate corporate
existence of the Transitory Subsidiary shall cease and the Company shall
continue as the surviving corporation in the Merger (the "Surviving
Corporation").  The "Effective Time" shall be the time at which the Surviving
Corporation files a certificate of merger or other appropriate documents
prepared and executed in accordance with Section 607.1105 of the Florida
Business Corporation Act (the "Certificate of Merger") with the Secretary of
State of the State of Florida, which Certificate of Merger shall be filed as
soon as

                                      -5-
<PAGE>

practical after the Closing (as defined below). The Merger shall have the
effects set forth in Section 607.1106 of the Florida Business Corporation Act.

     1.2  The Closing.  The closing of the transactions contemplated by this
          -----------
Agreement (the "Closing") shall take place at the offices of Hale and Dorr LLP
in Boston, Massachusetts, commencing at 9:00 a.m. local time on July 27, 2000,
or, if all of the conditions to the obligations of the Parties to consummate the
transactions contemplated hereby have not been satisfied or waived by such date,
on such mutually agreeable later date as soon as practicable (and in any event
not later than three business days) after the satisfaction or waiver of all
conditions (excluding the delivery of any documents to be delivered at the
Closing by any of the Parties) set forth in Article V hereof (the "Closing
Date").

     1.3  Actions at the Closing.  At the Closing:

          (d)  the Buyer shall make the Initial Shares (as defined below)
available to a bank trust company or other entity reasonably satisfactory to the
Company appointed by the Buyer to act as the exchange agent (the "Exchange
Agent") in accordance with Section 1.7;

          (e)  the Buyer, Robert Gordon and Benjamin Holzemer (Mr. Gordon and
Mr. Holzemer are referred to herein as the "Indemnification Representatives")
and State Street Bank and Trust Company (the "Escrow Agent") shall execute and
deliver an Escrow Agreement, in substantially the form attached hereto as
Exhibit A (the "Escrow Agreement") and the Buyer shall deliver to the Escrow
---------
Agent a certificate for the Escrow Shares (as defined below) being placed in
escrow on the Closing Date pursuant to and to be held and disbursed in
accordance with the Escrow Agreement and Section 1.10 below; and

          (f)  the Buyer shall deliver to Chase H&Q Securities, Inc. ("Chase") a
certificate in the name Chase or an affiliate thereof evidencing 195,000 shares
of Buyer

                                      -6-
<PAGE>

Common Stock, subject to equitable adjustment in the event of any stock split,
stock dividend, reverse stock split or similar event affecting the Buyer Common
Stock between the date hereof and the Effective Time (the "Chase Shares").

     1.4  Additional Action.  The Surviving Corporation shall, at any time after
          -----------------
the Effective Time, take any necessary or desirable action, including executing
and delivering any document, in the name and on behalf of either the Company or
the Transitory Subsidiary, in order to vest or to perfect or confirm of record
in the Surviving Corporation the title to any property, rights, privileges,
powers and franchises of either the Transitory Subsidiary or the Company.

     1.5  Conversion of Shares.  At the Effective Time, by virtue of the Merger
          --------------------
and without any action on the part of any Party or the holder of any of the
following securities:

          (a)  Each share of common stock, $0.001 par value per share, of the
Company ("Common Shares") issued and outstanding immediately prior to the
Effective Time (other than Common Shares owned beneficially by the Buyer or the
Transitory Subsidiary, Dissenting Shares (as defined below) and Common Shares
held in the Company's treasury) shall be converted into and represent the right
to receive (subject to the provisions of Section 1.10) such number of shares of
common stock, $0.00001 par value per share, of the Buyer ("Buyer Common Stock")
as is equal to the Common Conversion Ratio (as defined below).

          (b)  Each share of Preferred Stock, $0.001 par value per share, of the
Company ("Preferred Shares"; and, together with the Common Shares, the "Company
Shares") issued and outstanding immediately prior to the Effective Time (other
than Preferred Shares owned beneficially by the Buyer or the Transitory
Subsidiary, Dissenting Shares and Preferred Shares held in the Company's
treasury) shall be converted into and represent the right to receive (subject to
the provisions of Section 1.10) such number of shares of Buyer Common Stock as
is equal to the Preferred Conversion Ratio (as defined below).

          (c)  The "Common Conversion Ratio" shall be the fraction obtained by
dividing (i) the difference of (A) the product of (I) the quotient obtained by
dividing (aa) the sum of (1) the number of outstanding shares of Buyer Common
Stock (as defined below) immediately prior to the Effective Time (after giving
effect to the conversion into Buyer Common Stock of all outstanding Buyer
Preferred Stock (as defined below)) and (2) the number of shares of Buyer Common
Stock issuable upon exercise of all options to purchase Buyer Common Stock and
warrants to purchase Buyer Common Stock outstanding immediately prior

                                      -7-
<PAGE>

to the Effective Time by (bb) 0.78 multiplied by (II) 0.22 minus (B) the sum of
(I) the Pre-Closing Indebtedness Amount (as defined below) divided by $12.00 and
(II) the Pre-Closing Accounts Payable Excess (as defined below) divided by
$12.00 by (ii) the sum of (X) the number of outstanding Common Shares
immediately prior to the Effective Time (after giving effect to the conversion
into Common Shares of all outstanding Preferred Shares), (Y) the number of
Common Shares issuable upon exercise of all Options and Warrants outstanding
immediately prior to the Effective Time and (Z) the number of Chase Shares. The
"Preferred Conversion Ratio" shall be the result obtained by multiplying the
Common Conversion Ratio by the number of Common Shares into which each Preferred
Share is convertible immediately prior to the Effective Time. Each of the Common
Conversion Ratio and the Preferred Conversion Ratio shall be subject to
equitable adjustment in the event of any stock split, stock dividend, reverse
stock split or similar event affecting the Buyer Common Stock or the Company
Shares between the date hereof and the Effective Time. Stockholders of record of
the Company immediately prior to the Effective Time ("Company Stockholders")
shall be entitled to receive immediately at Closing in the aggregate the shares
of Buyer Common Stock into which their Company Shares were converted pursuant to
this Section 1.5 minus the Escrow Shares (as defined below) (the "Initial
Shares"); the Buyer shall deposit in escrow at Closing pursuant to Section 1.10
the number of shares of Buyer Common Stock equal to the sum, rounded to the
nearest whole number, of (i) 15% of the shares of Buyer Common Stock into which
the Company Shares were converted pursuant to this Section 1.5 and (ii) the
product obtained by multiplying the number of Chase Shares by 0.15, which shares
shall be held and disposed of in accordance with the terms of the Escrow
Agreement (the "Escrow Shares"). The Initial Shares and the Escrow Shares shall
together be referred to herein as the "Merger Shares."

          (d)  Two business days prior to the Closing, the Company shall deliver
to the Buyer a certificate (the "Pre-Closing Certificate") indicating (i) the
amount of outstanding Indebtedness (as defined below) of the Company as of the
immediately preceding business day (the "Pre-Closing Indebtedness Amount") and
(ii) the amount by which the accounts payable of the Company as of the
immediately preceding business day (excluding up to $800,000 directly relating
to purchases for the British Telecom Contract (as defined below) and up to
$1,150,000 directly relating to the MCI Litigation (as defined below)),
calculated in accordance with United States generally accepted accounting
principles ("GAAP") and on a basis consistent with the accounting methods,
treatments, principles and procedures used in the preparation of the Financial
Statements referred to in Section 2.6 of this Agreement for the fiscal year
ended December 31, 1999 (to the extent consistent with GAAP), is greater than
$2,500,000 (such amount being hereinafter referred to as the "Pre-Closing
Accounts Payable Excess"). The Pre-

                                      -8-
<PAGE>

Closing Certificate shall be executed by the Chief Executive Officer and the
Chief Financial Officer of the Company, and the statements therein shall be
deemed to be representations and warranties of the Company made pursuant to this
Agreement. For purposes of this paragraph, "Indebtedness" shall mean (without
duplication), (A) every obligation of the Company or any Subsidiary for money
borrowed, (B) every obligation of the Company or any Subsidiary evidenced by
bonds, debentures, notes or other similar instruments, (C) every reimbursement
obligation of the Company or any Subsidiary with respect to letters of credit,
bankers' acceptances or similar facilities issued for the account of the Company
or such Subsidiary and (D) every obligation of the type referred to in clauses
(A) through (C) of another party the payment of which the Company or any
Subsidiary has guaranteed or is responsible or liable for, directly or
indirectly, as obligor, guarantor or otherwise (but only, in the case of clause
(D), to the extent the Company or such Subsidiary has guaranteed or is
responsible or liable for such obligations), but "Indebtedness" shall exclude
trade payables, guarantees of subsidiary trade payables, and leasing obligations
including capital lease obligations. Neither the Company nor any Subsidiary
shall incur, assume or guarantee any new or additional Indebtedness not included
in the Pre-Closing Indebtedness Amount or any capital leases prior to the
Effective Time.

          (e)  The Merger Shares shall be subject to adjustment after the
Closing Date as follows:

               (i)   In the sole discretion of the Buyer, not later than 30 days
after the Closing Date, the Buyer may prepare and deliver to the Indemnification
Representatives an unaudited consolidated balance sheet of the Company and the
Company Subsidiaries (the "Closing Balance Sheet") as of the close of business
of the Closing Date. If prepared, the Closing Balance Sheet shall be prepared in
accordance with GAAP and on a basis consistent with the accounting methods,
treatments, principles and procedures used in the preparation of the Financial
Statements referred to in Section 2.6 of this Agreement for the fiscal year
ended December 31, 1999 (to the extent consistent with GAAP), and without giving
effect to the transactions contemplated by this Agreement.

               (ii)  The Closing Balance Sheet delivered pursuant to paragraph
(i) above shall be accompanied by a statement setting forth the amount by which
the amount of accounts payable as shown on the Closing Balance Sheet (excluding
up to $800,000 directly relating to purchases of hardware for the British
Telecom Contract (as defined below) and up to $1,150,000 directly relating to
the MCI Litigation (as defined below)) is greater than the sum of

                                      -9-
<PAGE>

$2,500,000 and the Pre-Closing Accounts Payable Excess, if any (the "Closing
Date Accounts Payable Excess").

               (iii)  In the event that the Indemnification Representatives in
good faith dispute the Closing Balance Sheet or the calculation of the Closing
Date Accounts Payable Excess, the Indemnification Representatives shall notify
the Buyer in writing (the "Dispute Notice") of the amount, nature and basis of
such dispute, within 15 calendar days after delivery of the Closing Balance
Sheet. In the event of such a dispute, the parties hereto shall first use
reasonable efforts to resolve such dispute among themselves. If the parties are
unable to resolve the dispute within 30 calendar days after delivery of the
Closing Balance Sheet, the dispute shall be submitted to PricewaterhouseCoopers
LLP (or if such accountants are unable or refuse to serve in such capacity, such
other nationally recognized accounting firm that is not the primary independent
accounting firm for any of the parties but is mutually acceptable to both of the
parties as may be designated by the Boston office of the American Arbitration
Association) (the "Neutral Accountants") for resolution. The Neutral Accountants
shall be required to resolve the dispute within 30 days after submission. The
determination of the Neutral Accountants as to the resolution of any dispute
shall be binding and conclusive upon all parties hereto. Nothing herein shall be
construed to authorize or permit the Neutral Accountants to (a) determine any
question or matter whatever under or in connection with this Agreement except
the determination of what adjustments, if any, must be made in the items
reflected in the Closing Balance Sheet that are the subject of objections by the
Indemnification Representatives, (b) determine an adjustment to an item on the
Closing Balance Sheet that is outside of the range defined by amounts as finally
proposed by the Indemnification Representatives and the Buyer, respectively, or
(c) apply any accounting methods, treatments, principles or procedures other
than as described in Section 1.5(d). All determinations pursuant to this
paragraph (iii) shall be in writing and shall be delivered to the parties
hereto. Any award made pursuant to this Section 1.5(d) may be entered in and
enforced by any court having jurisdiction thereover.

               (iv)   The fees and expenses incurred in connection with the
preparation of the Closing Balance Sheet shall be borne by the Buyer. The fees
and expenses of the Neutral Accountants in connection with the resolution of
disputes pursuant to paragraph (iii) above shall be shared equally by the
Company Stockholders (with such fees and expenses being paid out of the Escrow
Shares) and the Buyer; provided, that if the Neutral Accountants determine that
                       --------
one party has adopted a position or positions with respect to the Closing
Balance Sheet that is frivolous or clearly without merit, the Neutral
Accountants may, in their discretion, assign a greater portion of any such fees
and expenses to such party.

                                     -10-
<PAGE>

               (v)  Immediately upon the expiration of the 15-day period for
giving the Dispute Notice, if no Dispute Notice is given, or immediately upon
the resolution of disputes, if any, pursuant to paragraph (iii) above, the
Company Stockholders shall be obligated to pay to the Buyer out of the Escrow
Shares an amount equal to the Closing Date Accounts Payable Excess; provided,
                                                                    --------
however, that such amount payable by the Company Stockholders to the Buyer shall
-------
be recoverable by the Buyer only pursuant to the terms of the Escrow Agreement
established in accordance with Section 1.10 below. If the Closing Date Accounts
Payable Excess is less than $25,000, the Closing Stockholders shall not be
obligated to pay any amounts to the Buyer pursuant to this Section 1.5(e).

          (f)  Each Company Share held in the Company's treasury immediately
prior to the Effective Time and each Company Share owned beneficially by the
Buyer or the Transitory Subsidiary shall be cancelled and retired without
payment of any consideration therefor.

          (g)  Each share of common stock, $0.01 par value per share, of the
Transitory Subsidiary issued and outstanding immediately prior to the Effective
Time shall be converted into and thereafter evidence one share of common stock,

     1.6  Dissenting Shares.
          -----------------

          (a)  For purposes of this Agreement, "Dissenting Shares" means Company
Shares held as of the Effective Time by a Company Stockholder who has not voted
such Company Shares in favor of the adoption of this Agreement and the Merger
and with respect to which the exercise of dissenters' rights shall have been
duly demanded and perfected in accordance with Section 607.1320 of the Florida
Business Corporation Act and not effectively withdrawn or forfeited prior to the
Effective Time. Dissenting Shares shall not be converted into or represent the
right to receive Merger Shares, unless such Company Stockholder shall have
forfeited his, her or its dissenters' rights under the Florida Business
Corporation Act or properly withdrawn his, her or its notice of election to
dissent. If such Company Stockholder has so forfeited or withdrawn his, her or
its notice of election to dissent with respect to such Dissenting Shares, then
(i) as of the occurrence of such event, such holder's Dissenting Shares shall
cease to be Dissenting Shares and shall be converted into and represent the
right to receive the Merger Shares issuable in respect of such Company Shares
pursuant to Section 1.5, and (ii) promptly following the occurrence of such
event, the Buyer shall deliver to the Exchange Agent a certificate representing
the number of Initial Shares to which such holder is entitled pursuant to
Section 1.5 (which shares shall be considered Initial Shares for all purposes of
this Agreement)

                                     -11-
<PAGE>

and shall deliver to the Escrow Agent a certificate representing the number of
Escrow Shares to which such holder is entitled pursuant to Section 1.5 (which
shares shall be considered Escrow Shares for all purposes of this Agreement).

          (b)  The Company shall give the Buyer (i) prompt notice of any written
notice of election to dissent with respect to any Company Shares, withdrawals of
such notices, and any other instruments that relate to such notices received by
the Company and (ii) the opportunity to direct all negotiations and proceedings
with respect to notices of election to dissent under the Florida Business
Corporation Act. The Company shall not, except with the prior written consent of
the Buyer, make any payment with respect to any exercise of dissenters' rights
with respect to Company Shares or offer to settle or settle any such exercise.

     1.7  Exchange of Shares.
          ------------------

          (a)  Prior to the Effective Time, the Buyer shall appoint the Exchange
Agent to effect the exchange for the Initial Shares of certificates that,
immediately prior to the Effective Time, represented Company Shares converted
into Merger Shares pursuant to Section 1.5 (including any Company Shares
referred to in the last sentence of Section 1.6(a)) ("Certificates"). On the
Closing Date, the Buyer shall make the Initial Shares available to the Exchange
Agent, in trust for the benefit of holders of Certificates. As soon as
practicable after the Effective Time, the Buyer shall cause the Exchange Agent
to send a notice and a transmittal form to each holder of a Certificate advising
such holder of the effectiveness of the Merger and the procedure for
surrendering to the Exchange Agent such Certificate in exchange for the Initial
Shares issuable pursuant to Section 1.5. Each holder of a Certificate, upon
proper surrender thereof to the Exchange Agent in accordance with the
instructions in such notice, shall be entitled to receive in exchange therefor
(subject to any taxes required to be withheld) the Initial Shares issuable
pursuant to Section 1.5. Until properly surrendered, each such Certificate shall
be deemed for all purposes to evidence only the right to receive a certificate
for the Initial Shares and the Escrow Shares (subject to the provisions of this
Agreement and the Escrow Agreement) issuable pursuant to Section 1.5. Holders of
Certificates shall not be entitled to receive certificates for the Initial
Shares to which they would otherwise be entitled until such Certificates are
properly surrendered.

          (b)  If any Initial Shares are to be issued in the name of a person
other than the person in whose name the Certificate surrendered in exchange
therefor is registered, it shall be a condition to the issuance of such Initial
Shares that (i) the Certificate so surrendered shall be transferable, and shall
be properly assigned, endorsed or accompanied by appropriate stock

                                     -12-
<PAGE>

powers, (ii) such transfer shall otherwise be proper and (iii) the person
requesting such transfer shall pay to the Exchange Agent any transfer or other
taxes payable by reason of the foregoing or establish to the satisfaction of the
Exchange Agent that such taxes have been paid or are not required to be paid.
Notwithstanding the foregoing, neither the Exchange Agent nor any Party shall be
liable to a holder of Company Shares for any Initial Shares issuable to such
holder pursuant to Section 1.5 that are delivered to a public official pursuant
to applicable abandoned property, escheat or similar laws.

          (c)  In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed, the Buyer shall issue in
exchange for such lost, stolen or destroyed Certificate the Initial Shares
issuable in exchange therefor pursuant to Section 1.5. The Board of Directors of
the Buyer may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed Certificate to give
the Buyer a bond in such sum as it may in good faith reasonably direct as
indemnity against any claim that may be made against the Buyer with respect to
the Certificate alleged to have been lost, stolen or destroyed.

          (d)  No dividends or other distributions that are payable to the
holders of record of Buyer Common Stock as of a date on or after the Closing
Date shall be paid to former Company Stockholders entitled by reason of the
Merger to receive Initial Shares until such holders surrender their Certificates
for certificates representing the Merger Shares. Upon such surrender, the Buyer
shall pay or deliver to the persons in whose name the certificates representing
such Initial Shares are issued any dividends or other distributions that are
payable to the holders of record of Buyer Common Stock as of a date on or after
the Closing Date and which were paid or delivered between the Effective Time and
the time of such surrender; provided that no such person shall be entitled to
receive any interest on such dividends or other distributions.

     1.8  Fractional Shares.  No certificates or scrip representing fractional
          -----------------
Initial Shares shall be issued to former Company Stockholders upon the surrender
for exchange of Certificates, and such former Company Stockholders shall not be
entitled to any voting rights, rights to receive any dividends or distributions
or other rights as a stockholder of the Buyer with respect to any fractional
Initial Shares that would have otherwise been issued to such former Company
Stockholders.  In lieu of any fractional Initial Shares that would have
otherwise been issued, each former Company Stockholder that would have been
entitled to receive a fractional Initial Share shall, upon proper surrender of
such person's Certificates, receive such whole number of

                                     -13-
<PAGE>

Initial Shares as is equal to the precise number of Initial Shares to which such
person would be entitled, rounded up or down to the nearest whole number (with a
fractional interest equal to .5 rounded to the nearest odd number); provided
that each such holder shall receive at least one Initial Share.

     1.9  Options and Warrants.
          --------------------

          (a)  As of the Effective Time, all options to purchase Common Shares
issued by the Company pursuant to its stock option plans or otherwise
("Options"), whether vested or unvested, shall be assumed by the Buyer.
Immediately after the Effective Time, each Option outstanding immediately prior
to the Effective Time shall be deemed to constitute an option to acquire, on the
same terms and conditions as were applicable under such Option at the Effective
Time, such number of shares of Buyer Common Stock as is equal to the number of
Common Shares subject to the unexercised portion of such Option multiplied by
the Common Conversion Ratio (with any fraction resulting from such
multiplication to be rounded down to the nearest whole number). The exercise
price per share of each such assumed Option shall be equal to the exercise price
of such Option immediately prior to the Effective Time, divided by the Common
Conversion Ratio (rounded up to the nearest whole cent). The term,
exercisability, vesting schedule, status as an "incentive stock option" under
Section 422 of the Internal Revenue Code of 1986 (as amended, the "Code"), if
applicable, and all of the other terms of the Options shall otherwise remain
unchanged.

          (b)  As soon as practicable after the Effective Time, the Buyer or the
Surviving Corporation shall deliver to the holders of Options appropriate
notices setting forth such holders' rights pursuant to such Options, as amended
by this Section 1.9, and the agreements evidencing such Options shall continue
in effect on the same terms and conditions (subject to the amendments provided
for in this Section 1.9 and such notice).

          (c)  The Buyer shall take all corporate action necessary to reserve
for issuance a sufficient number of shares of Buyer Common Stock for delivery
upon exercise of the Options assumed in accordance with this Section 1.9.

          (d)  The Company shall cause the termination, as of the Effective
Time, of all outstanding warrants to purchase Company Shares (the "Warrants")
that remain unexercised.

securing the indemnification obligations of the Indemnifying Stockholders (as

business days after the eighteen month anniversary of the consummation of the
Company's disposition of Interglobe Telecommunications (International) plc,

indemnification obligations of the Indemnifying Stockholders with respect to
Section 6.1(e) and (ii) Escrow Shares with a Value of $1,000,000 shall be held
in escrow until two years after the Closing Date for the purpose of securing the
indemnification obligations of the Indemnifying Stockholders with respect to
Section 6.1(e) and breaches of the representations and warranties of the Company
set forth in Section 2.9 (and the portion of the Company Certificate pertaining
thereto). The Escrow Shares shall be held as a trust fund and shall not be
subject to any lien, attachment, trustee process or any other judicial process
of any creditor of any party, and shall be held and disbursed solely for the
purposes and in accordance with the terms of the Escrow Agreement.

          (b)  The adoption of this Agreement and the approval of the Merger by
the Company Stockholders shall constitute approval by the Company Stockholders
voting to approve the Merger of the Escrow Agreement and of all of the
arrangements relating thereto, including without limitation the placement of the
Escrow Shares in escrow and the appointment of the Indemnification

Effective Time, except to the extent such representations and warranties are
specifically made as of a particular date or as of the date of this Agreement
(in which case such representations and warranties shall be true and correct as
of such date);

to become due or otherwise), monetary damages, fines, fees, penalties, interest

     6.2  Indemnification by the Buyer. The Buyer shall indemnify the
          ----------------------------
Indemnifying Stockholders in respect of, and hold them harmless against, any and
all Damages incurred or suffered by the Indemnifying Stockholders resulting
from, relating to or constituting any misrepresentation, breach of warranty or
failure to perform any covenant or agreement of the Buyer or the Transitory
Subsidiary contained in this Agreement or the Buyer Certificate.

     6.3  Indemnification Claims.
          ----------------------

          (a)  A party entitled, or seeking to assert rights, to indemnification
under this Article VI (an "Indemnified Party") shall give written notification
to the party from whom indemnification is sought (an "Indemnifying Party") of
the commencement of any suit or proceeding relating to a third-party claim for
which indemnification pursuant to this Article VI may be sought. Such
notification shall be given within 20 business days after receipt by the
Indemnified Party of notice of such suit or proceeding, and shall describe in
reasonable detail (to the extent known by the Indemnified Party) the facts
constituting the basis for such suit or proceeding and the amount of the claimed
damages; provided, however, that no delay on the part of the Indemnified Party
in notifying the Indemnifying Party shall relieve the Indemnifying Party of any
liability or obligation hereunder except to the extent of any damage or
liability caused by or arising out of such failure. Within 20 days after
delivery of such notification, the Indemnifying Party may, upon written notice
thereof to the Indemnified Party, assume control of the defense of such suit or
proceeding with counsel reasonably satisfactory to the Indemnified Party;
provided that (i) the Indemnifying Party may only assume control of such defense
if (A) it acknowledges in writing to the Indemnified Party that any damages,
fines, costs or other liabilities that may be assessed against the Indemnified
Party in connection with such suit or proceeding constitute Damages for which
the Indemnified Party shall be indemnified pursuant to this Article VI and (B)
the ad damnum is less than or equal to the amount of Damages for which the
Indemnifying Party is liable under this Article VI and (ii) the Indemnifying
Party may not assume control of the defense of a suit or proceeding involving
criminal liability or in which equitable relief is sought against the
Indemnified Party. If the Indemnifying Party does not so assume control of such
defense, the Indemnified Party shall control such defense. The party not
controlling such defense (the"Non-controlling Party") may participate therein at
its own expense; provided that if the Indemnifying Party assumes control of such
defense and the Indemnified Party reasonably concludes that the Indemnifying
Party and the Indemnified Party have conflicting interests or different defenses
available with respect to such suit or proceeding, the reasonable fees and
expenses of counsel to the Indemnified Party shall be considered "Damages" for
purposes of this Agreement. The party controlling such defense (the

                                     -58-
<PAGE>

"Controlling Party") shall keep the Non-controlling Party advised of the status
of such suit or proceeding and the defense thereof and shall consider in good
faith recommendations made by the Non-controlling Party with respect thereto.
The Non-controlling Party shall furnish the Controlling Party with such
information as it may have with respect to such suit or proceeding (including
copies of any summons, complaint or other pleading which may have been served on
such party and any written claim, demand, invoice, billing or other document
evidencing or asserting the same) and shall otherwise cooperate with and assist
the Controlling Party in the defense of such suit or proceeding. The
Indemnifying Party shall not agree to any settlement of, or the entry of any
judgment arising from, any such suit or proceeding without the prior written
consent of the Indemnified Party, which shall not be unreasonably withheld or
delayed. The Indemnified Party shall not agree to any settlement of, or the
entry of any judgment arising from, any such suit or proceeding without the
prior written consent of the Indemnifying Party, which shall not be unreasonably
withheld or delayed.

               (b)  In order to seek indemnification under this Article VI, an
Indemnified Party shall give written notification (a "Claim Notice") to the
Indemnifying Party which contains (i) a description and the amount (the "Claimed
Amount") of any Damages incurred or reasonably expected to be incurred by the
Indemnified Party, (ii) a statement that the Indemnified Party is entitled to
indemnification under this Article VI for such Damages and a reasonable
explanation of the basis therefor, and (iii) a demand for payment (in the manner
provided in paragraph (c) below) in the amount of such Damages. If the
Indemnified Party is seeking to enforce such claim pursuant to the Escrow
Agreement, the Indemnifying Party shall deliver a copy of the Claim Notice to
the Escrow Agent.

               (c)  Within 20 days after delivery of a Claim Notice, the
Indemnifying Party shall deliver to the Indemnified Party a written response
(the "Response") in which the Indemnifying Party shall: (i) agree that the
Indemnified Party is entitled to receive all of the Claimed Amount (in which
case the Response shall be accompanied by a payment by the Indemnifying Party to
the Indemnified Party of the Claimed Amount, by check or by wire transfer;
provided that if the Indemnified Party is seeking to enforce such claim pursuant
to the Escrow Agreement, the Indemnifying Party and the Indemnified Party shall
deliver to the Escrow Agent, within three days following the delivery of the
Response, a written notice executed by both parties instructing the Escrow Agent
to distribute to the Buyer such number of Escrow Shares as have an aggregate
Value (as defined below) equal to the Claimed Amount), (ii) agree that the
Indemnified Party is entitled to receive part, but not all, of the Claimed
Amount (the "Agreed Amount") (in which case the Response shall be accompanied by
a

                                     -59-
<PAGE>

payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount,
by check or by wire transfer; provided that if the Indemnified Party is seeking
to enforce such claim pursuant to the Escrow Agreement, the Indemnifying Party
and the Indemnified Party shall deliver to the Escrow Agent, within three days
following the delivery of the Response, a written notice executed by both
parties instructing the Escrow Agent to distribute to the Buyer such number of
Escrow Shares as have an aggregate Value equal to the Agreed Amount) or (iii)
dispute that the Indemnified Party is entitled to receive any of the Claimed
Amount. If the Indemnifying Party in the Response disputes its liability for all
or part of the Claimed Amount, the Indemnifying Party and the Indemnified Party
shall follow the procedures set forth in Section 6.3(d) for the resolution of
such dispute (a "Dispute"). For purposes of this Article VI, the "Value" of any
Escrow Shares shall be $12.00 per share of the Buyer Common Stock (subject to
equitable adjustment in the event of any stock split, stock dividend, reverse
stock split or similar event affecting the Buyer Common Stock after the date of
this Agreement) multiplied by the number of such Escrow Shares; provided,
                                                                --------
however, that, with respect to Escrow Shares withheld from the disbursement of
-------
Escrow Shares to the Indemnifying Shareholders on the first anniversary of the
Escrow Agreement pursuant to Section 3(c)(ii) or delivered in satisfaction of an
indemnity claim made pursuant to a Claim Notice initially delivered after the
first anniversary of the Closing with respect to a breach of the representations
and warranties set forth in Section 2.9, "Value" shall be the greatest of (i)
$12.00 per share, (ii) the value per share provided to Buyer Common Stock in the
last private placement or series of private placements prior to the first
anniversary of the Closing of Buyer Common Stock or preferred stock of the Buyer
in which the proceeds to the Buyer were at least $2,000,000, or (iii) as of the
date of the first anniversary of the Closing, the closing sales price of Buyer
Common Stock on a national securities exchange, or if not, on the Nasdaq
National Market System, or if there have been no sales on any such exchange or
the Nasdaq National Market System on such day, the average of the highest bid
and lowest asked prices on the Nasdaq System at the end of such day, or if on
any such day such security is not quoted on the Nasdaq System, the average of
the highest bid and lowest asked prices on such day in domestic over the counter
market as reported on the National Quotation Bureau, Incorporated, or any
similar organization (subject to equitable adjustment in the event of any stock
split, stock dividend, reverse stock split or similar event affecting the Buyer
Common Stock after the date of this Agreement) multiplied by the number of such
Escrow Shares.

               (d)  During the 60-day period following the delivery of a
Response that reflects a Dispute, the Indemnifying Party and the Indemnified
Party shall use good faith efforts to resolve the Dispute. If the Dispute is not
resolved within such 60-day period, the Indemnifying Party and the Indemnified
Party shall discuss in good faith the submission of the

                                     -60-
<PAGE>

Dispute to a mutually acceptable alternative dispute resolution procedure (which
may be non-binding or binding upon the parties, as they agree in advance) (the
"ADR Procedure"). In the event the Indemnifying Party and the Indemnified Party
agree upon an ADR Procedure, such parties shall, in consultation with the chosen
dispute resolution service (the "ADR Service"), promptly agree upon a format and
timetable for the ADR Procedure, agree upon the rules applicable to the ADR
Procedure, and promptly undertake the ADR Procedure. The provisions of this
Section 6.3(d) shall not obligate the Indemnifying Party and the Indemnified
Party to pursue an ADR Procedure or prevent either such party from pursuing the
Dispute in a court of competent jurisdiction; provided that, if the Indemnifying
Party and the Indemnified Party agree to pursue an ADR Procedure, neither the
Indemnifying Party nor the Indemnified Party may commence litigation or seek
other remedies with respect to the Dispute prior to the completion of such ADR
Procedure. Any ADR Procedure undertaken by the Indemnifying Party and the
Indemnified Party shall be considered a compromise negotiation for purposes of
federal and state rules of evidence, and all statements, offers, opinions and
disclosures (whether written or oral) made in the course of the ADR Procedure by
or on behalf of the Indemnifying Party, the Indemnified Party or the ADR Service
shall be treated as confidential and, where appropriate, as privileged work
product. Such statements, offers, opinions and disclosures shall not be
discoverable or admissible for any purposes in any litigation or other
proceeding relating to the Dispute (provided that this sentence shall not be
construed to exclude from discovery or admission any matter that is otherwise
discoverable or admissible). The fees and expenses of any ADR Service used by
the Indemnifying Party and the Indemnified Party shall be shared equally by the
Indemnifying Party and the Indemnified Party. If the Indemnified Party is
seeking to enforce the claim that is the subject of the Dispute pursuant to the
Escrow Agreement, the Indemnifying Party and the Indemnified Party shall deliver
to the Escrow Agent, promptly following the resolution of the Dispute (whether
by mutual agreement, pursuant to an ADR Procedure, as a result of a judicial
decision or otherwise), a written notice executed by both parties instructing
the Escrow Agent as to what (if any) portion of the Escrow Shares shall be
distributed to the Buyer and/or the Indemnifying Stockholders (which notice
shall be consistent with the terms of the resolution of the Dispute).

               (e)  Notwithstanding the other provisions of this Section 6.3, if
a third party asserts (other than by means of a lawsuit) that an Indemnified
Party is liable to such third party for a monetary or other obligation which may
constitute or result in Damages for which such Indemnified Party may be entitled
to indemnification pursuant to this Article VI, and such Indemnified Party
reasonably determines that it has a valid business reason to fulfill such
obligation, then (i) such Indemnified Party shall be entitled to satisfy such
obligation, without

                                     -61-
<PAGE>

prior notice to or consent from the Indemnifying Party, (ii) such Indemnified
Party may subsequently make a claim for indemnification in accordance with the
provisions of this Article VI, and (iii) such Indemnified Party shall be
reimbursed, in accordance with the provisions of this Article VI, for any such
Damages for which it is entitled to indemnification pursuant to this Article VI
(subject to the right of the Indemnifying Party to dispute the Indemnified
Party's entitlement to indemnification, or the amount for which it is entitled
to indemnification, under the terms of this Article VI).

               (f)  For purposes of this Section 6.3 and the last two sentences
of Section 6.4, (i) if the Indemnifying Stockholders comprise the Indemnifying
Party, any references to the Indemnifying Party (except provisions relating to
an obligation to make or a right to receive any payments provided for in Section
6.3 or Section 6.4) shall be deemed to refer to the Indemnification
Representatives, and (ii) if the Indemnifying Stockholders comprise the
Indemnified Party, any references to the Indemnified Party (except provisions
relating to an obligation to make or a right to receive any payments provided
for in Section 6.3 or Section 6.4) shall be deemed to refer to the
Indemnification Representatives. Except in relation to any claim made directly
against any Indemnifying Stockholder (as permitted under Section 6.5(b)), the
Indemnification Representatives shall have full power and authority on behalf of
each Indemnifying Stockholder to take any and all actions on behalf of, execute
any and all instruments on behalf of, and execute or waive any and all rights
of, the Indemnifying Stockholders under this Article VI. The Indemnification
Representatives shall have no liability to any Indemnifying Stockholder for any
action taken or omitted on behalf of the Indemnifying Stockholders pursuant to
this Article VI.

          6.4  Survival of Representations and Warranties. All representations
               ------------------------------------------
and warranties contained in this Agreement, the Company Certificate or the Buyer
Certificate shall (a) survive the Closing and any investigation made by or on
behalf of an Indemnified Party and (b) shall expire on the date one year
following the Closing Date, except that (i) the representations and warranties
set forth in Section 2.2 (and the portion of the Company Certificate relating
thereto) shall survive the Closing without limitation and (ii) the
representations and warranties set forth in Section 2.9 (and the portion of the
Company Certificate relating thereto) shall expire on the date two years
following the Closing Date. If an Indemnified Party delivers to an Indemnifying
Party, before expiration of a representation or warranty, a Claim Notice based
upon a breach of such representation or warranty, then such representation or
warranty shall survive until, but only for purposes of, the resolution of the
matter covered by such notice.

     6.5  Limitations.
          -----------

          (a)  Notwithstanding anything to the contrary herein, neither the
Indemnifying Stockholders nor the Buyer shall be liable under this Article VI
(i) for an aggregate amount in excess of the dollar amount equal to the Value
multiplied by the number of Escrow Shares or (ii) unless and until the aggregate
Damages for which they or it would otherwise be liable exceed $250,000 (at which
point the Indemnifying Stockholders and the Buyer shall become liable for the
aggregate Damages, and not just amounts in excess of $250,000), provided that
the limitation set forth above in subclause (ii) shall not apply to a claim
pursuant to Section 6.1(a) relating to a breach of the representations and
warranties made pursuant to Section 1.5(d) or set forth in Section 2.2 or 2.9
(or the portion of the Company Certificate relating thereto) or to a claim
pursuant to Section 6.1(d) or 6.1(e). For purposes solely of the calculation of
the amount of Damages pursuant to a claim of indemnification under this Article
VI, all representations and warranties of the Company in Article II and all
representations and warranties of the Buyer and the Transitory Subsidiary in
Article III shall be construed as if the term "material" and any reference to
"Company Material Adverse Effect" and "Buyer Material Adverse Effect" (and
variations thereof) were omitted from such representations and warranties.

          (b)  Notwithstanding anything to the contrary herein, other than with
respect to claims for the breach of the representations and warranties set forth
in Section 2.2 (or the portion of the Company Certificate relating thereto) and
Section 6.1(b) and (c), the Escrow Agreement shall be the exclusive means for
the Buyer to enforce its rights under this Article VI. In the event of a breach
of the representations and warranties set forth in Section 2.2 (or the portion
of the Company Certificate relating thereto) or indemnification obligations
arising from Section 6.1(b) or (c), (i) the Buyer shall not attempt to collect
any Damages directly from the Indemnifying Stockholders unless there are no
remaining Escrow Shares held in escrow pursuant to the Escrow Agreement and (ii)
other than with respect to the Escrow Shares and the Escrow Agreement, the
liability of the Indemnifying Stockholders shall be several (in proportion to
each Indemnifying Stockholder's pro rata ownership share of the Company on a
fully diluted basis as of the Effective Time), and not joint, in nature.

          (c)  Except with respect to claims based on fraud, after the Closing,
the rights of the Indemnified Parties under this Article VI shall be the
exclusive remedy of the Indemnified Parties with respect to claims resulting
from or relating to any misrepresentation, breach of warranty or failure to
perform any covenant or agreement contained in this Agreement.

                                     -63-
<PAGE>

          (d)  No Indemnifying Stockholder shall have any right of contribution
against the Company or the Surviving Corporation with respect to any breach by
the Company of any of its representations, warranties, covenants or agreements.

          (e)  Each Indemnifying Stockholder, by voting to approve this
Agreement, executing an Investment Representation Letter or surrendering his,
her or its Certificate or accepting any consideration pursuant to Section 1,
acknowledges and irrevocably agrees (i) that the consideration to which each
such Indemnifying Stockholder is entitled hereunder is subject to the
indemnification obligations as contemplated and limited hereunder, (ii) that the
Escrow Agent shall be, and hereby is, authorized from time to time to deliver
all or any portion of the Escrow Shares in satisfaction of the obligations
hereunder and as otherwise provided pursuant to this Article VI and as
contemplated in the Escrow Agreement, and (iii) to all other obligations of the
Indemnifying Stockholders hereunder.

                                  ARTICLE VII
                              REGISTRATION RIGHTS

     7.1  Incidental Registration.
          -----------------------

          (a)  Whenever the Buyer proposes to file with the Securities and
Exchange Commission ("SEC") a registration statement (a "Registration
Statement") (including for this purpose a Registration Statement effected by
Buyer for stockholders other than the Company Stockholders) covering shares of
Buyer Common Stock (other than the Buyer's initial public offering of Buyer
Common Stock and filings on Forms S-4 or S-8, or any successor forms thereto) at
any time and from time to time, it will, prior to such filing, give written
notice to all Company Stockholders of its intention to do so. Upon the written
request of one or more Company Stockholders given within 20 days after the Buyer
provides such notice, the Buyer shall use its Reasonable Best Efforts to cause
all Merger Shares which the Buyer has been requested by such Company Stockholder
or Stockholders to register to be registered under the Securities Act; provided
that the Buyer shall have the right to postpone or withdraw any registration
effected pursuant to this Section 7.1 without obligation to any Company
Stockholder.

          (b)  If the registration for which the Buyer gives notice pursuant to
Section 7.1(a) is a registered public offering involving an underwriting, the
Buyer shall so advise the Company Stockholders as a part of the written notice
given pursuant to Section 7.1(a). In such event, the right of any Company
Stockholder to include his, her or its Merger Shares in such

                                     -64-
<PAGE>

registration pursuant to Section 7.1 shall be conditioned upon such Company
Stockholder's participation in such underwriting on the terms set forth herein.
All Company Stockholders proposing to distribute their securities through such
underwriting shall enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for the underwriting by the Buyer;
provided, however, that if other stockholders of Buyer have the right to select
such underwriter(s), then such underwriter(s) shall be selected for the
underwriting by such other stockholders of Buyer and such Company Stockholders
proposing to distribute their securities through such underwriting.
Notwithstanding any other provision of this Section 7.1, if the managing
underwriter determines that the inclusion of all shares requested to be
registered would adversely affect the offering, the Buyer may limit the number
of Merger Shares to be included in the registration and underwriting. The Buyer
shall so advise all holders of Merger Shares requesting registration, and the
number of shares that are entitled to be included in the registration and
underwriting shall be allocated in the following manner. The number of shares
that may be included in such registration and underwriting shall be allocated
among all Company Stockholders and other holders of registration rights
requesting registration in proportion, as nearly as practicable, to the
respective number of shares of Buyer Common Stock (on an as-converted basis)
which they held at the time the Buyer gives the notice specified in Section
7.1(a). If any Company Stockholder or other holder of registration rights would
thus be entitled to include more securities than such holder requested to be
registered, the excess shall be allocated among other requesting Company
Stockholders and other holders pro rata in the manner described in the preceding
sentence. If any holder of Merger Shares disapproves of the terms of any such
underwriting, such person may elect to withdraw therefrom by written notice to
the Buyer, and any Merger Shares or other securities excluded or withdrawn from
such underwriting shall be withdrawn from such registration.

     7.2  S-3 Registration.
          ----------------

          (a)  At any time after the Buyer becomes eligible to file a
Registration Statement on Form S-3 (or any successor form relating to secondary
offerings), a Company Stockholder or Stockholders may request that the Buyer
effect the registration of Merger Shares with an aggregate value of at least
$5,000,000 (based on the public market price on the date of such request).

          (b)  Upon receipt of any request for registration pursuant to this
Section 7.2, the Buyer shall promptly give written notice of such proposed
registration to all other Company Stockholders. Such Company Stockholders shall
have the right, by giving written notice to the

                                     -65-
<PAGE>

Buyer within 30 days after the Buyer provides its notice, to elect to have
included in such registration such of their Merger Shares as such Company
Stockholders may request in such notice of election, subject in the case of an
underwritten offering to the approval of the managing underwriter as provided in
Section 7.2(c) below. Thereupon, the Buyer shall, as expeditiously as possible,
use its Reasonable Best Efforts to effect the registration on Form S-3 of all
Merger Shares which the Buyer has been requested to so register.

          (c)  If the initiating Company Stockholders intend to distribute the
Merger Shares covered by their request by means of an underwriting, they shall
so advise the Buyer as a part of their request made pursuant to Section 7.2(a),
and the Buyer shall include such information in its written notice referred to
in Section 7.2(b). The right of any other Company Stockholder to include his,
her or its Merger Shares in such registration pursuant to Section 7.2(a) shall
be conditioned upon such other Company Stockholder's participation in such
underwriting on the terms set forth herein. If the managing underwriter
determines that the marketing factors require a limitation of the number of
shares to be underwritten, the number of Merger Shares to be included in a
Registration Statement filed pursuant to this Section 7.2 shall be reduced pro
rata among the requesting Company Stockholders based on the quotient of the
total Merger Shares to be included in the Registration Statement, divided by the
total number of Merger Shares that requested registration.

          (d)  The Buyer shall have the right to select the managing
underwriter(s) for any underwritten offering requested pursuant to Section
7.2(a), subject to the approval of initiating Company Stockholders holding at
least a majority of the Merger Shares held by all of the initiating Company
Stockholders, which approval will not be unreasonably withheld.

          (e)  The Buyer shall not be required to effect more than two
registrations pursuant to Section 7.2(a). For purposes of this Section 7.2(e), a
Registration Statement shall not be counted until such time as such Registration
Statement has been declared effective by the SEC; provided, however, that a
registration shall be counted if the initiating Company Stockholders withdraw
their request for such registration and elect not to pay the registration
expenses therefor (unless such withdrawal is a result of information concerning
the business or financial condition of the Buyer which is made known to the
Company Stockholders after the date on which such registration was requested, in
which case the registration shall not be counted and the Buyer shall pay the
registration expenses therefor).

          (f)  If at the time of any request to register Merger Shares pursuant
to this Section 7.2, the Buyer is engaged or has plans to engage in a registered
public offering or is

                                     -66-
<PAGE>

engaged in any other activity which, in the good faith determination of the
Buyer's Board of Directors, would be adversely affected by the requested
registration, then the Buyer may at its option direct that such request be
delayed for a period not in excess of 120 days from the date of such request,
such right to delay a request to be exercised by the Buyer not more than once in
any 12-month period.

          (g)  The registration rights set forth in Section 7.1 and Section 7.2
shall terminate, with respect to each Merger Share, on the earlier of (i) the
second anniversary of the Buyer's initial public offering of Buyer Common Stock
and (ii) the date such Merger Share can be then be sold pursuant to Rule 144(k)
under the Securities Act.

     7.3  Registration Procedures.
          -----------------------

          (a)  In connection with the filing by the Buyer of a Registration
Statement, the Buyer shall furnish to each Company Stockholder a copy of the
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act.

          (b)  The Buyer shall use its best efforts to register or qualify the
Merger Shares covered by the Registration Statement under the securities laws of
each state of the United States; provided, however, that the Buyer shall not be

required in connection with this paragraph (b) to qualify as a foreign
corporation or execute a general consent to service of process in any
jurisdiction.

          (c)  If the Buyer has delivered preliminary or final prospectuses to
the Company Stockholders and after having done so the prospectus is amended or
supplemented to comply with the requirements of the Securities Act, the Buyer
shall promptly notify the Company Stockholders and, if requested by the Buyer,
the Company Stockholders shall immediately cease making offers or sales of
shares under the Registration Statement and return all prospectuses to the
Buyer. The Buyer shall promptly provide the Company Stockholders with revised or
supplemented prospectuses and, following receipt of the revised or supplemented
prospectuses, the Company Stockholders shall be free to resume making offers and
sales under the Registration Statement.

          (d)  The Buyer shall pay the expenses incurred by it in connection
with any Registration Statements filed, postponed or withdrawn pursuant to
Section 7.1 and the first registration statement declared effective pursuant to
or any registration statement withdrawn by Company Stockholders as provided in
Section 7.2, including all registration and filing fees,

                                     -67-

exchange listing fees, fees and expenses of counsel for the Buyer, and fees and
expenses of accountants for the Buyer, but excluding (i) any brokerage fees,

Stockholders in connection with sales under the Registration Statement and (ii)
the fees and expenses of any counsel retained by Company Stockholders. In
connection with the second registration statement declared effective pursuant to
Section 7.2, the selling Company Stockholders shall pay, pro rata, all expenses
of the offering.

     7.4  Requirements of Company Stockholders. The Buyer shall not be required
          ------------------------------------
to include any Merger Shares in the Statement unless:

          (a)  the Company Stockholder owning such shares furnishes to the Buyer
in writing such information regarding such Company Stockholder and the proposed
sale of Merger Shares by such Company Stockholder as the Buyer may reasonably
request in writing in connection with the Registration Statement or as shall be
required in connection therewith by the SEC or any state securities law
authorities; and

          (b)  such Company Stockholder shall have provided to the Buyer its
written agreement:

               (i)   to indemnify the Buyer and each of its directors and
officers against, and hold the Buyer and each of its directors and officers
harmless from, any losses, claims, damages, expenses or liabilities (including
reasonable attorney's fees) to which the Buyer or such directors and officers
may become subject by reason of any statement or omission in the Registration
Statement made in reliance upon, or in conformity with, a written statement by
such Company Stockholder furnished pursuant to this Section 7.4; and

               (ii)  to report to the Buyer sales made pursuant to the
Registration Statement.

     7.5  Indemnification. The Buyer agrees to indemnify and hold harmless each
          ---------------
Company Stockholder whose shares are included in the Registration Statement
against any losses, claims, damages, expenses or liabilities to which such
Company Stockholder may become subject by reason of any untrue statement of a
material fact contained in the Registration Statement or any omission to state
therein a fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages, expenses
or liabilities arise out of or are based upon information furnished to the Buyer
by or on behalf of a Company Stockholder for use in the Registration Statement.
The Buyer shall have

                                     -68-
<PAGE>

the right to assume the defense and settlement of any claim or suit for which
the Buyer may be responsible for indemnification under this Section 7.5.

     7.6  Assignment of Rights. A Company Stockholder may not assign any of its
          ---------------------
rights under this Article VII except in connection with the transfer of some or
all of his, her or its Merger Shares to a child or spouse, or trust for their
benefit or, in the case of a partnership, to the partners of such partnership
pursuant to a pro rata distribution, provided each such transferee agrees in a
written instrument delivered to the Buyer to be bound by the provisions of this
Article VII.
