Shares issued and outstanding immediately prior to the Effective Time (the

                                       3
<PAGE>

2.02(b)(i), the "Class B Cash Consideration" and, together with the Class A Cash
Consideration the "Cash Consideration"); and

            (ii) An amount equal to (x) (A) One Million Dollars ($1,000,000) (or
such lesser amount as may be payable to the former holders of the Company Common
Stock pursuant to the Escrow Agreement), multiplied by (B) the Class B Multiple,
divided by (y) the Outstanding Class B Common Stock, which amount will be placed
in escrow with the Escrow Agent pursuant to the Escrow Agreement to secure the
payment of the Closing Adjustment (the aggregate amount of cash deposited with
the Escrow Agent pursuant to Section 2.02(a)(ii) of this Merger Agreement and
this Section 2.02(b)(ii), the "Escrowed Consideration" and, together with the
Cash Consideration, the "Merger Consideration").

      (c) At the Effective Time, all shares of Company Common Stock shall (i) be
converted into the right to receive the cash determined in accordance with this
Article II, (ii) no longer be outstanding, (iii) automatically be canceled and
(iv) cease to exist, and each certificate previously representing any such
shares of Company Common Stock (each a "Certificate") shall thereafter represent
the right to receive the Merger Consideration determined in accordance with
Sections 2.02(a), 2.02(b) and 2.04 of this Merger Agreement.

      (d) At the Effective Time, all shares of Company Common Stock that are
owned by Company as treasury stock and all shares of Company Common Stock that
are owned directly or indirectly by Acquiror, any of its Subsidiaries, Company,
or any Company Subsidiary, other than (i) any shares of Company Common Stock
held directly or indirectly in trust accounts, managed accounts and the like or
otherwise held in a fiduciary capacity that are beneficially owned by Persons
other than Acquiror, any of its Subsidiaries, Company, or any Company
Subsidiary, and (ii) any shares of Company Common Stock held by Acquiror, any of
its Subsidiaries, Company, or any Company Subsidiary, in respect of a debt
previously contracted, shall be canceled and shall cease to exist and no
consideration shall be delivered in exchange therefor.

      (e) Notwithstanding anything in this Merger Agreement to the contrary and
unless otherwise provided by applicable law, shares of Company Common Stock that
are issued and outstanding immediately prior to the Effective Time and that are
owned by Company Stockholders who have properly demanded payment of the fair
value of their stock (the "Dissenting Shares") within the meaning of Section
3-202 of Maryland Law shall not be converted into the right to receive the
Merger Consideration unless and until such Company Stockholders shall have
failed to perfect or shall have effectively withdrawn their demand, or lost
their right of payment under applicable law. If any such Company Stockholder
shall have failed to perfect or shall have effectively withdrawn or lost such
right of payment, each share of Company Common Stock held by such Company
Stockholder shall thereupon be deemed converted into the right to receive and
exchangeable for, at the Effective Time, the Merger Consideration pursuant to
Sections 2.02 and 2.04 of this Merger Agreement. Subject to the terms and
conditions of this Merger Agreement, at and after the Effective Time, any holder
of shares of Company Common Stock who complies with Section 3-203 of Maryland
Law (a "Company Dissenting Stockholder") shall be entitled to obtain payment
from Surviving Corporation of the fair value of such Company Dissenting
Stockholder's shares of Company Common Stock as determined pursuant to Sections
3-207 or 3-210 of Maryland Law; provided, however, that, to the extent
permissible under Maryland Law,


                                       4
<PAGE>

no such payment shall be made unless and until such Company Dissenting
Stockholder has surrendered to the Exchange Agent the Certificate representing
the shares of Company Common Stock for which payment is being made.

      (f) Company shall give Acquiror (i) prompt notice of any written notice of
intent to demand payment for shares filed pursuant to Section 3-203 of Maryland
Law received by Company, withdrawals of such notices, and any other instruments
served in connection with such notices pursuant to the relevant provisions of
Maryland Law and received by Company and (ii) the opportunity to direct all
negotiations and proceedings with respect to such notices under Maryland Law
consistent with the obligations of Company thereunder. Company shall not, except
with the prior written consent of Acquiror (which shall not be unreasonably
withheld), (A) make any payment with respect to any such notice, (B) offer to
settle or settle any such notices or (C) waive any failure to timely deliver a
written notice in accordance with the Maryland Law.

SECTION 2.03 Acquiror to Deliver Cash

At or prior to the Effective Time, Acquiror shall deposit, or shall cause to be
deposited, (a) with First Union National Bank, or any other agent mutually
acceptable to the Parties (the "Exchange Agent"), for the benefit of the holders
of Certificates, for payment in accordance with this Article II, an amount of
cash equal to the Cash Consideration representing the cash (such deposit plus
interest thereon being hereinafter referred to as the "Exchange Fund") to be
paid pursuant to Section 2.04 of this Merger Agreement in exchange for the
Certificates, and (b) with the Escrow Agent, an amount of cash equal to the
Escrowed Consideration representing the cash to be distributed and released in
accordance with the terms and provisions of this Merger Agreement and of the
Escrow Agreement.

SECTION 2.04 Exchange of Cash

      (a) Not later than three (3) business days after the Effective Time, the
Exchange Agent shall mail (via first class U.S. mail, postage prepaid) to each
holder of record of Certificates a form letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent) with instructions for use in effecting the surrender of the Certificates
in exchange for cash pursuant to this Section 2.04 and Section 2.02 of this
Merger Agreement. Company shall have the right to review both the letter of
transmittal and the instructions prior to their being finalized. Upon surrender
of a Certificate for exchange and cancellation to the Exchange Agent, together
with such letter of transmittal, duly executed, the holder of such Certificate
shall be entitled to receive in exchange therefor a check in the amount to which
such holder is entitled pursuant to the provisions of Section 2.02(a)(i) or
Section 2.02(b)(i) of this Merger Agreement, as the case may be, and the
Certificate so surrendered shall forthwith be canceled. The Exchange Agent shall
send the foregoing check(s) to each such holder (via first-class U.S. mail,
postage prepaid) no later than the third business day after the Exchange Agent
receives such holder's duly executed and completed transmittal letter. Company
shall fix a date, in accordance with Maryland Law and Company's organizational
documents, as a record date (the "Record Date") for the determination of the
holders of Certificates entitled to receive cash as provided in this Section
2.04, notwithstanding any transfer of any Company Common Stock on the books of
Company after the Record Date is fixed as


                                       5
<PAGE>

aforesaid. Not less than fifteen (15) days prior to the Effective Time, Company
shall provide Acquiror with a list of holders of Certificates on the Record
Date.

      (b) After the close of business on the Record Date, there shall be no
transfers on the stock transfer books of Company of the shares of Company Common
Stock.

      (c) Any portion of the Exchange Fund that remains unclaimed by the Company
Stockholders for three (3) months after the Effective Time shall be returned to
Acquiror. Any Company Stockholders who have not complied with this Article II
before such portion of the Exchange Fund is returned to Acquiror shall
thereafter look only to Acquiror for payment of their Merger Consideration
determined pursuant to this Merger Agreement, without any interest thereon.
Notwithstanding the foregoing, none of Acquiror, Company, the Exchange Agent or
any other Person shall be liable to any former holder of shares of Company
Common Stock for any amount properly delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.

      (d) 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 and, if required by Acquiror,
the posting by such person of a bond in such amount as Acquiror may reasonably
direct as indemnity against any claim that may be made against it with respect
to such Certificate, the Exchange Agent will issue in exchange for such lost,
stolen or destroyed Certificate the cash deliverable in respect thereof pursuant
to this Merger Agreement.

SECTION 2.05 Escrowed Consideration; Determination of Closing Adjustment

      (a) Escrowed Consideration. The Escrowed Consideration will be placed in
escrow pursuant to the Escrow Agreement and in accordance with Sections
2.02(a)(ii), 2.02(b)(ii) and 2.03 of this Merger Agreement. The Escrowed
Consideration shall be held in escrow pursuant to the Escrow Agreement as
security for the payment of the Closing Adjustment as determined in the manner
described in Section 2.05(b) of this Merger Agreement. The Escrowed
Consideration shall be released to the Acquiror and/or the Company Stockholders,
as the case may be, only in accordance with the terms of the Escrow Agreement.

      (b) Determination of Closing Adjustment. The "Closing Adjustment" shall
equal (i) the amount, if any, by which the actual amount of cash and the fair
market value of the marketable securities of the Company and the Company
Subsidiary on the Closing Date is less than (a) the estimated amount of cash and
the estimated value of the marketable securities of the Company as set forth on
the Estimated Balance Sheet required to be delivered to Acquiror pursuant to
Section 7.02(k) of this Merger Agreement (in the event that the proviso set
forth in clause (c) of the definition of "Adjusted Merger Amount" did not
prevent the balance of such clause (c) from being taken into account in the
preparation of the Estimated Balance Sheet) or (b) $1,700,000 (in the event that
such proviso did prevent the balance of such clause (c) from being taken into
account in the preparation of the Estimated Balance Sheet), provided however,
if, on the Closing Date, the cash and fair market value of the marketable
securities is less than $1,700,000 and the net asset value of the Company,
calculated in accordance with generally accepted accounting principles, is
greater than or equal to Five Million Eight Hundred Seventy


                                       6
<PAGE>

Five Thousand Dollars ($5,875,000), then the amount by which the cash and the
fair market value of the marketable securities owned by the Company is less than
$1,700,000 shall not be deducted for purposes of determining the Closing
Adjustment, plus (ii) any Losses sustained by Acquiror or Surviving Corporation
as a result of any breaches of the representations and warranties of the Company
contained in this Merger Agreement and which are discovered by the Acquiror as a
result of the audit of the consolidated financial statements of the Company as
of the Closing Date by Arthur Andersen LLP, the Acquiror's independent public
accountants, as hereinafter provided. The Company will use its best efforts to
close its books and records for the period ending on the Closing Date within
twenty (20) days after the Closing Date and shall deliver to the Acquiror or, at
the request of the Acquiror, to Acquiror and Arthur Andersen LLP, such books and
records as shall be requested by Acquiror or Arthur Andersen LLP to enable
Arthur Andersen LLP to perform an audit of the consolidated financial statements
of the Company as of the Closing Date and to determine the amount of the Closing
Adjustment based thereon. Upon receipt of such books and records, the Acquiror
shall use its best efforts to cause Arthur Andersen LLP to complete an audit of
the consolidated financial statements of the Company and to calculate the amount
of the Closing Adjustment within thirty (30) days following receipt of the books
and records of the Company. Acquiror shall deliver to the Stockholders'
Representative and the Escrow Agent a copy of such audited financial statements
and the computations of the amount of the Closing Adjustment promptly upon
receipt of such items from Arthur Andersen LLP. The Stockholders' Representative
shall have the right to review and copy the computations and workpapers used in
connection with the preparation of the audited financial statements and the
computation of the Closing Adjustment, if any. If the Stockholders'
Representative disagrees with the computation of the Closing Adjustment, the
Stockholders' Representative shall so notify the Acquiror and the Escrow Agent
in writing within ten (10) days after the date of receipt of the audited
financial statements and the computation of the Closing Adjustment, specifying
in detail any point of disagreement; provided, however, if the Stockholders'
Representative fails to notify the Acquiror in writing of the Stockholders'
Representative's disagreement within such ten (10) day period, the determination
of the Closing Adjustment shall be final, conclusive and binding on the Parties
for purposes of determining the amount of the Escrowed Consideration to be
released to the former holders of Company Common Stock pursuant to the Escrow
Agreement, but shall not limit Acquiror's other rights pursuant to this Merger
Agreement or any other document delivered in connection with this Merger
Agreement. The Acquiror and the Stockholders' Representative shall negotiate in
good faith to resolve any such disagreement. If any such disagreement cannot be
resolved by the Acquiror and the Stockholders' Representative within fifteen
(15) days after the Acquiror has received notice from the Stockholders'
Representative in accordance with the preceding sentence of the existence of
such disagreement, the Acquiror and the Stockholders' Representative shall
jointly select a nationally recognized independent public accounting firm (which
has not performed any service since January 1, 1996 for either the Company or
the Acquiror or any of their respective Affiliates (the "Accounting Firm")), to
act as an arbitrator to resolve as expeditiously as possible all points of
disagreement with respect to the Closing Adjustment (or, in the event they are
unable to agree, either may request the Washington, D.C. office of the American
Arbitration Association to make such selection, which shall be final and binding
on the Parties). All determinations made by the Accounting Firm with respect to
the Closing Adjustment shall be final, conclusive and binding on the Parties
hereto for purposes of


                                       7
<PAGE>

determining the amount of the Escrowed Consideration to be released to the
former holders of Company Common Stock pursuant to the Escrow Agreement, but
shall not limit Acquiror's other rights pursuant to this Merger Agreement or any
other document delivered in connection with this Merger Agreement. The fees and
expenses of the Accounting Firm shall be borne by the non-prevailing Party.
Notwithstanding the foregoing, in the event the Closing Adjustment exceeds the
Escrowed Consideration, the Acquiror shall have, in addition to any other rights
it may have under this Merger Agreement or any other documents delivered in
connection with this Merger Agreement, the right to make an offset against the
amounts payable under the Consulting/Non-Competition Arrangement in an amount
equal to the amount by which Closing Adjustment exceeds the Escrowed
Consideration.

      (c) Appointment of Stockholders' Representative. John G. Hannon shall, by
virtue of the Merger, be appointed attorney-in-fact and authorized and empowered
to act, for and on behalf of any or all of the Company Stockholders (with full
power of substitution in the premises), in connection with the provisions of
this Section 2.05 and the Escrow Agreement as they relate to the Company and the
Company Stockholders generally, and such other matters as are reasonably
necessary for the consummation of the transactions contemplated hereby
including, without limitation, (i) to review all determinations of the Closing
Adjustment and, to the extent deemed appropriate, dispute, question the accuracy
of, compromise, settle or otherwise resolve any and all such determinations,
(ii) to compromise on their behalf with Acquiror any claims asserted thereunder,
(iii) to authorize payments to be made with respect to the Closing Adjustment,
(iv) to execute and deliver on behalf of the Company Stockholders any documents
or agreement contemplated by or necessary or desirable in connection with this
Merger Agreement or the Escrow Agreement and (v) to take such further actions
including coordinating and administering post-closing matters related to the
rights and obligations of the Company Stockholders as are authorized in this
Merger Agreement and the Escrow Agreement (the above named representative, as
well as any subsequent representative of the Company Stockholders appointed by
the Company Stockholders who previously held a majority of the Company Common
Stock being referred to herein as the "Stockholders' Representative"). The
Stockholders' Representative shall not be liable to any Company Stockholder,
Acquiror, the Surviving Corporation or their respective Affiliates or any other
Person with respect to any action taken or omitted to be taken by the
Stockholders' Representative in his role as Stockholders' Representative under
or in connection with this Merger Agreement unless such action or omission
results from or arises out of fraud, gross negligence, willful misconduct or bad
faith on the part of the Stockholders' Representative. Acquiror, Acquiror Sub
and the Surviving Corporation shall be entitled to rely on such appointment and
treat such Stockholders' Representative as the duly appointed attorney-in-fact
of each Company Stockholder. Each Company Stockholder who votes in favor of the
Merger pursuant to the terms hereof, by such vote and without any further
action, and each Company Stockholder who receives Merger Consideration in
connection with the Merger, by acceptance thereof and without any further
action, confirms such appointment and authority.

      (d) Record Retention. Acquiror, the Company and the Stockholder
Representative agree that following the Closing through the date of the final
determination of the Closing Adjustment that they will not destroy any records
pertaining to the final determination of the Closing Adjustment.

      (d) Neither Company nor any Company Subsidiary has any obligations for

or circumstances which could give rise to a reasonable expectation that any
authority may assess any additional Taxes for any period for which Company Tax
Returns have been filed. There is no dispute or claim concerning any liability
for taxes of Company or any Company Subsidiary either (i) claimed or raised by
any authority in writing or (ii) as to which Company has knowledge based upon

      (f) by either Acquiror or Company if any of the conditions provided in

                                   ARTICLE IX

                      SURVIVAL OF REPRESENTATIONS; REMEDIES

SECTION 9.01 Survival of Representations

All representations, warranties, covenants, indemnities and other agreements
made by any party to this Merger Agreement herein, shall be deemed made on and
as of the Effective Time as though such representations, warranties, covenants,
indemnities and other agreements were made on and as of such date, and all such
representations, warranties, covenants, indemnities and other agreements shall
survive for a period of twelve (12) months after the Effective Time; provided,
however, that the representations set forth in Section 3.16 (Taxes and Tax
Matters), Section 3.15 (Pension and Benefit Plans) and Section 3.24
(Environmental Matters) shall survive until the expiration of the applicable
statute of limitations and provided further that in the event of fraud all such

SECTION 9.02 Indemnification by Principal Stockholder and Networking Ventures,
LLC; Right to Offset

      (a) Each of the Principal Stockholder and Networking Ventures, LLC, a
Maryland limited liability company ("NVLLC"), hereby agrees to, jointly and
severally, indemnify, defend and hold Acquiror, the Surviving Corporation and
their respective officers and directors, and each person, if any, who controls
or may control Acquiror or the Surviving Corporation within


                                       44
<PAGE>

the meaning of the Securities Act (all such persons hereinafter are referred to
individually as an "Acquiror Indemnified Person" and collectively as "Acquiror
Indemnified Persons," but in no event shall any stockholder of the Company prior
to the Effective Time be such an Acquiror Indemnified Person) harmless against
all Losses resulting from, imposed upon or incurred by any Acquiror Indemnified
Person, directly or indirectly, as a result of any of the following, anything in
this Merger Agreement (except for Section 9.02(c)) to the contrary
notwithstanding:

            (i) any inaccuracy or breach of a representation or warranty of the
Company given or made by the Company in this Merger Agreement, in the Articles
of Merger or in the Company Disclosure Letter or in any certificate, document or
agreement delivered by or on behalf of the Company pursuant hereto; and

            (ii) any failure by the Company to perform or comply with any
covenant or agreement contained in this Merger Agreement, in the Articles of
Merger or in the Company Disclosure Letter or in any certificate, document or
agreement delivered by or on behalf of the Company pursuant hereto.

      (b) In the event, from time to time, any Acquiror Indemnified Person
determines that it has suffered a Loss for which indemnification is available
pursuant to this Article IX, the following procedure shall be followed:

            (i) Acquiror Indemnified Person shall give written notice of any
such claim (a "Loss Notice") to the Principal Stockholder specifying in
reasonable detail the amount of the claimed Loss (the "Loss Amount") and the
basis for such Loss and that the Acquiror intends to offset against amounts
payable under the Consulting/Non-Competition Arrangement the amount of any such
Loss.

            (ii) Within twenty (20) days after delivery of a Loss Notice, the
Principal Stockholder shall provide to Acquiror and the Acquiror Indemnified
Person (if not the same Person), a written response (a "Response Notice") in
which the Principal Stockholder will (i) agree that an offset in the full Loss
Amount may be made against amounts payable under the Consulting/Non-Competition
Arrangement, (ii) agree that an offset in an amount equal to part, but not all,
of the Loss Amount (the "Agreed Amount") may be made against amounts payable
under the Consulting/Non-Competition Arrangement or (iii) contest making any
offset against amounts payable under the Consulting/Non-Competition Arrangement.
The Principal Stockholder may contest an offset against the amounts payable
under the Consulting/Non-Competition Arrangement upon a good faith belief that
all or such portion of such offset does not constitute a Loss for which the
Acquiror Indemnified Person is entitled to indemnification under this Article
IX. If no Response Notice is delivered by the Principal Stockholder within such
twenty (20) day period, the Principal Stockholder shall be deemed to have agreed
that an offset in the full Loss Amount may be made against the amounts payable
under the Consulting/Non-Competition Arrangement.

            (iii) If the Principal Stockholder in the Response Notice agrees (or
is deemed to have agreed) that an offset may be made against the amounts payable
under the Consulting/Non-Competition Arrangement in an amount equal to the Loss
Amount, the Acquiror


                                       45
<PAGE>

may, promptly following the earlier of the required delivery date of the
Response Notice or the delivery of the Response Notice, cause an offset in the
amount of the Loss Amount to be made to the amounts payable under the
Consulting/Non-Competition Arrangement.

            (iv) If the Principal Stockholder in the Response Notice agrees that
an offset in an amount equal to part, but not all, of the Loss Amount (the
"Agreed Amount") may be made against the amounts payable under the
Consulting/Non-Competition Arrangement, the Acquiror may, promptly following the
earlier of the required delivery date of the Response Notice or the delivery of
the Response Notice, cause an offset in the amount of the Agreed Amount to be
made to the amounts payable under the Consulting/Non-Competition Arrangement.

            (v) If the Principal Stockholder in the Response Notice contests an
offset against the amounts payable under the Consulting/Non-Competition
Arrangement equal to all or any part of the Loss Amount (the "Contested
Amount"), the Acquiror Indemnified Person and the Principal Stockholder shall
negotiate in good faith to resolve any such dispute. If any such dispute cannot
be resolved within fifteen (15) days after the receipt by the Acquiror of the
Response Notice, the Acquiror Indemnified Person and the Principal Stockholder
shall submit the matter to the Washington, D.C. office of the American
Arbitration Association ("AAA") for binding arbitration to be conducted in
accordance with the AAA commercial arbitration rules in effect at the time such
matter is submitted. If any such matter is submitted to the AAA as provided
herein, (A) each of the Acquiror Indemnified Person and the Principal
Stockholder will furnish to AAA such workpapers and other documents and
information as AAA may request and will be afforded the opportunity to present
to AAA any material relevant to the matter, (B) the determination by AAA, as set
forth in a notice delivered to the Acquiror Indemnified Person and the Principal
Stockholder by AAA, will be binding and conclusive on such parties and (iii) the
non-prevailing party will pay the fees of the AAA for such determination.

            (vi) All action and inaction by the Principal Stockholder taken or
not taken pursuant to this Article IX shall be deemed taken or not taken, as the
case may be, by the Principal Stockholder on his behalf and the behalf of NVLLC
and shall bind NVLLC as fully as if taken or not taken, as the case may be, by
NVLLC.

      (c) The indemnity obligations of the Principal Stockholder and NVLLC under
this Article IX shall first be satisfied through a claim against the Escrowed
Consideration (including, without limitation, Escrowed Consideration
attributable to Company Common Stock owned by Company Stockholders other than
the Principal Stockholder), to the extent that the same has not been released
from escrow, and then by the exercise by the Acquiror of the right of offset
against the amounts payable under the Consulting/Non-Competition Arrangement.
The Escrowed Consideration and amounts payable under the
Consulting/Non-Competition Arrangement shall in no way be deemed to be a
limitation on the recourse available to any Acquiror Indemnified Person for the
indemnification obligations of the Principal Stockholder and NVLLC for any
breach of the representations and warranties set forth in Section 3.01
(Organization and Qualification), Section 3.04 (Capitalization), Section 3.05
(Authority; Binding Obligation), Section 3.16 (Tax and Tax Matters), or Section
3.24 (Environmental Matters) or for any Losses resulting from fraud on the part
of the Company, any Company Subsidiary or their respective officers or
directors. Following its exhaustion of its offset rights as set forth above,
Acquiror


                                       46
<PAGE>

shall have the right to enforce the indemnity obligations of the Principal
Stockholder for any breach of the representations and warranties set forth in
Sections 3.01, 3.04, 3.05, 3.16 or 3.24, or for fraud, through an action in a
court of competent jurisdiction.

      (d) Notwithstanding the foregoing, neither the Principal Stockholder nor
NVLLC shall have any liability under Section 9.02(a) until the cumulative amount
of all Losses with respect to such matters exceeds $25,000, following which the
Principal Stockholder and NVLLC shall be liable for the full amount of such
Losses back to and including the first dollar of such Losses. However, this
Section 9.02(d) shall not apply to any Losses arising out of or in connection
with any breach of any representations and warranties of the Company given or
made by the Company in this Merger Agreement, in the Articles of Merger or in
the Company Disclosure Letter or in any certificate, document or agreement
delivered by or on behalf of the Company pursuant hereto of which breach the
Company had knowledge at any time prior to the date on which such representation
and warranty was made or any intentional failure by the Company to perform or
comply with any covenant or agreement contained in this Merger Agreement, in the
Articles of Merger or in the Company Disclosure Letter or in any certificate,
document or agreement delivered by or on behalf of the Company pursuant hereto.

      (e) The exercise of such right of offset by Acquiror in good faith,
whether or not ultimately determined to be justified, will not constitute a
breach of this Merger Agreement. Neither the exercise of nor the failure to
exercise such right of offset will constitute an election of remedies or limit
Acquiror in any manner in the enforcement of any other remedies available to
Acquiror.

SECTION 9.03 Third Party Claims.

The obligations and liabilities of the Principal Stockholder and NVLLC with
