                          AGREEMENT AND PLAN OF MERGER
                          ----------------------------

          AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of November
30, 1999, by and between PartMiner, Inc., a New York corporation ("Buyer"),
PartMiner Acquisition Corp., a New York corporation and wholly-owned subsidiary
of Buyer ("PartMiner Sub"), IQXpert Holdings Inc., a Delaware corporation
("IQX"), Information Handling Services Inc., a Delaware corporation ("IHS" or
the "Majority Stockholder"), Thybo New Ventures Limited, a Bermuda corporation
("Thybo"), Emil H. Dahan, Michael J. Galvin, Patricia Tuxbury Salem, Peter W.
Jeng and James L. McAlarney, III (Thybo and Messrs. Dahan, Galvin, Jeng and
McAlarney and Ms. Salem collectively, the "Minority Stockholders"; and together
with the Majority Stockholder, the "Stockholders").

          WHEREAS, the Stockholders are the beneficial and record owners of
9,556,130 shares of IQX Common Stock (as defined in Section 4.3(a) hereof),
constituting all of the issued and outstanding capital stock of IQX (the " IQX
Shares"); and

          WHEREAS, the Boards of Directors of Buyer, PartMiner Sub and IQX deem
it advisable and in the best interests of such entities and their respective
shareholders that PartMiner Sub be merged with and into IQX in a transaction
whereby IQX will become a wholly-owned subsidiary of Buyer (the "Merger"), all
in accordance with the terms of this Agreement and applicable Law (as defined in
Section 4.10 hereof).

          NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements herein contained, the
parties hereby agree as follows:

          1.     THE MERGER.
                 ----------

          1.1.   The Merger.  Upon the terms and subject to the conditions of
                 ----------
this Agreement, at the Effective Time (as defined in Section 1.3 hereof),
PartMiner Sub shall be merged with and into IQX in accordance with the
applicable provisions of the Delaware General Corporation Law (the "DGCL") and
the New York Business Corporation Law (the "BCL"). Following the Effective Time,
the separate existence of PartMiner Sub shall cease and IQX shall be the
surviving corporation in the Merger (the "Surviving Corporation") and shall
continue its corporate existence under the laws of the State of Delaware.

          1.2.   Effects of the Merger.  At the Effective Time, (i) the
                 ---------------------
Certificate of Incorporation of IQX, as in effect immediately prior to the
Effective Time, shall be the Certificate of Incorporation of the Surviving
Corporation unless and until thereafter amended as provided by applicable Law or
such Certificate of Incorporation, and (ii) the By-laws of IQX, as in effect
immediately prior to the Effective Time, shall be the By-laws of the Surviving
Corporation unless and until thereafter amended as provided by applicable Law,
the Certificate of Incorporation of the Surviving Corporation or such By-laws.
Subject to the foregoing, any additional effects of the Merger shall be as
provided for by applicable Law.

          1.3.   Effective Time of the Merger.  Subject to the provisions of
                 ----------------------------
this Agreement, on or as soon as practicable after the Closing Date (as defined
in Section 2.1 hereof), certificates of merger (the "Certificates of Merger")
complying with the requirements of the DGCL and the BCL shall be executed by IQX
and PartMiner Sub and filed with the Secretaries
<PAGE>

of State of the States of Delaware and New York. The parties shall make all such
other filings or recordings in connection with the Merger when and as required
under the DGCL, the BCL or other applicable Law. The Merger shall become
effective at the time the Certificates of Merger are duly filed with the
Secretaries of State of the States of Delaware and New York, or at such later
time or date as may be specified in the Certificates of Merger as Buyer and IQX
shall agree (the time and date that the Merger becomes effective being
hereinafter referred to as the "Effective Time").

          1.4.   Directors.  The directors of PartMiner Sub immediately prior to
                 ---------
the Effective Time shall be the directors of the Surviving Corporation, until
the earlier of their resignation or removal or until their respective successors
are duly elected and qualified, as the case may be.

          1.5.   Officers.  The individuals set forth on Schedule 1.5 hereto,
                 --------                                ------------
who are the current officers of PartMiner Sub, shall be the officers of the
Surviving Corporation, until the earlier of their resignation or removal or
until their respective successors are duly elected and qualified, as the case
may be.

          1.6.   Effect of the Merger on Capital Stock.  At the Effective Time,
                 -------------------------------------
by virtue of the Merger and without any action on the part of any holder of the
capital stock of IQX or PartMiner Sub:

          (i)  Conversion of IQX Common Stock. Each issued and outstanding share
               ------------------------------
               of IQX Common Stock shall be converted into the right to receive
               0.0122633 of a share (the "Ratio") of Buyer Common Stock (as
               defined in Section 5.3 hereof), which amount shall be
               proportionately adjusted for any stock split or stock dividend
               effected between the date of this Agreement and the Effective
               Time. The aggregate amount of capital stock to be issued by Buyer
               in connection with the Merger shall be 117,190 restricted shares
               of Buyer Common Stock (the "Buyer Shares"), which number shall
               equal 20.5% of the total outstanding capital stock of Buyer
               (immediately after giving effect to the issuance of the Buyer
               Shares to the Stockholders). All shares of IQX Common Stock, when
               so converted, shall no longer be outstanding and shall be
               canceled and retired and cease to exist, and each holder of a
               certificate formerly representing any such shares shall cease to
               have any rights with respect thereto, except the right to receive
               the number of shares of Buyer Common Stock to be issued in
               accordance with the Ratio.

          (ii) Treatment of PartMiner Sub Stock. Each issued and outstanding
               --------------------------------
               share of common stock, no par value per share, of PartMiner Sub
               shall be converted into and become one fully paid and non-
               assessable share of common stock, $.001 par value per share, of
               the Surviving Corporation.

          2.     CLOSING.
                 -------

          2.1.   Time and Place.  The closing of the Merger (the "Closing")
                 --------------
shall take place at the offices of Kirkpatrick & Lockhart LLP, 1251 Avenue of

obligations hereunder and thereunder.  Each of the Majority Stockholder and

this Agreement and all other agreements and certificates referred to in or
contemplated by this Agreement and to perform its obligations hereunder and
thereunder.  Each of the Minority Stockholders (other than Thybo) is legally

referred to in or contemplated by this Agreement and to perform his/her
obligations hereunder and thereunder.  The execution, delivery and performance
of this Agreement and all other agreements and certificates referred to in or
contemplated by this Agreement have been duly authorized by all necessary
corporate action on the part of IQX, the Majority Stockholder and Thybo.  This
Agreement has been duly executed and delivered by IQX and each Stockholder and

may be limited by applicable bankruptcy, moratorium, insolvency, reorganization
or other similar laws now or hereafter in effect relating to or affecting
creditors' rights generally and general equitable principles (whether considered
in a proceeding in equity or at law).  Each of the Stockholders hereby consents
to and approves the Merger, this Agreement and the transactions referred to in
or contemplated by this Agreement.

          4.8.   Tax Matters.  IQX has timely filed any Tax Returns (as defined

in Section 12.2 hereof) that it has been required to file through the date
hereof, and has timely paid in full any Taxes (as defined in Section 12.2
hereof) which were due and payable by it through the date hereof. The provisions
for Taxes reflected on the IQX Interim Balance Sheet are adequate to cover all
accrued and unpaid Taxes of IQX for all periods ending on or before August 31,
1999, and nothing has occurred subsequent to that date to make such provisions
inadequate. IQX has established and is maintaining current accruals that are
accurately reflected in the books and records of IQX and are adequate for the
payment of any Taxes incurred but not yet due and payable with respect to the
property and operations of IQX through the date hereof and will establish and
maintain adequate accruals for the payment of any such Taxes in respect of the
period through the Closing Date. No waivers or extensions of any applicable
statute of limitations for the assessment or collection of Taxes with respect to
any Tax Returns of IQX are currently in effect or are currently proposed. IQX
has collected or withheld and paid over to the proper governmental or regulatory
bodies all amounts required to be so collected or withheld and paid over under
all applicable Laws. No action, suit, proceeding, investigation, audit, claim or
assessment is presently pending or, to IQX's and the Majority Stockholder's
knowledge (as defined in Section 12.2 hereof), threatened with regard to any
Taxes that relate to IQX for which IQX is or could reasonably be expected to be
liable. There is no unresolved claim by a taxing authority in any jurisdiction
where IQX does not anticipate to file Tax Returns that it is or could

                                       6
<PAGE>

reasonably be expected to be subject to taxation by such jurisdiction. There are
no Liens for Taxes (other than for Taxes not yet due and payable) upon any
assets or property of IQX.

          IQX (i) has not made any other election pursuant to the Code (as
defined in Section 12.2 hereof), other than elections that relate solely to
matters of accounting, depreciation, or amortization, that could reasonably be
expected to have a significant adverse effect on it, its financial condition,
its business as presently conducted or proposed to be conducted or any of its
properties or assets; and (ii) at no time has filed a consent to the application
of Section 341(f)(2) of the Code to any property or assets held, acquired or to
be acquired by it, and will not file any such consent prior to Closing.  IQX has
not made any payments, is not obligated to make any payments and is not a party
to any agreement that could obligate it to make any payments that are or would
not be deductible under Section 280G or Section 162(m) of the Code.  IQX is not
a party to or otherwise bound by any tax allocation, tax indemnity or tax
sharing agreement, and has no liability for the Taxes of any other entity under
Treasury Regulation (S) 1.1502-6 (or any similar provision of state, local or
foreign Law), as a transferee or successor, by contract, or otherwise.  Neither
IQX nor any of its subsidiaries is part of a consolidated group that includes
any other corporation for Tax filing or reporting purposes.

date hereof (a true and correct list of which is attached as Schedule 4.9
                                                             ------------

federal, state, local and foreign governmental or regulatory bodies necessary
for the conduct of its business and operations as currently conducted
(collectively, the "Permits").  All material Permits of IQX are set forth on

Schedule 4.10 hereto and are valid and in full force and effect.  No violations
-------------
have occurred in respect of any such Permit and no action or proceeding is
pending nor, to IQX's and the Majority Stockholder's knowledge, threatened to
revoke or limit any such Permit.  All material Permits are renewable by their
terms or in the ordinary course of business without the need of IQX or Buyer
complying with any special qualifications or procedures or paying any amounts
other than routine filing fees.

or certificates referred to in or contemplated by this Agreement by IQX and the
Stockholders, and the consummation of the transactions contemplated hereby and
thereby, will not (i) result in any Lien upon any of the property of IQX, or

terms and conditions of, result in a material modification of or accelerate or
trigger the rights of any person under, or constitute (or, with the giving of

declaration or filing with, any governmental authority or other person
("Consent") is required on the part of IQX or any Stockholder in connection with
the execution, delivery or performance of this Agreement or the consummation of
the transactions contemplated hereby. There are no payments, Liabilities or

affiliates of a material claim against IQX alleging any personal, property or
economic injury, loss or damage incurred as a result of or relating to the use
of any products sold by or on behalf of, or services rendered by, IQX.  There is

          4.18.  Title to Properties and Assets.  IQX has good title to all of
                 ------------------------------
the property and assets owned or purported to be owned by it which are reflected
as assets on the IQX Interim Balance Sheet and those not so reflected on the IQX
Interim Balance Sheet because not required to be reflected thereon, but which

Taxes not yet due and payable; and (ii) Liens of materialmen, mechanics,

Other than in the ordinary course of business, pursuant to the terms of this
Agreement or as disclosed on Schedules 4.14, 4.17 and 4.24 hereto, no person has

including guarantees and indemnities by IQX of Liabilities of any other person,

                                                  -------------

          4.20.  CAPSxpert Database.  All of the assets comprising the CAPSxpert
                 ------------------
Database (as defined in Section 12.2 hereof) and all of the DATA/PAL Assets (as
defined in Section 12.2 hereof) are owned solely, irrevocably and
unconditionally by IQX (and not by any affiliate or subsidiary of IQX).

          4.21.  Employee Benefit Plans.  Schedule 4.21 hereto contains a true
                 ----------------------   -------------
and complete list of all pension, profit sharing, retirement, deferred
compensation, incentive, bonus, severance, disability, hospitalization, medical
insurance, life insurance and other employee benefit plans, programs or
arrangements ("Employee Benefit Plans") maintained by IQX (or any organization
that may be aggregated with IQX under Sections 414(b), (c), (m) or (o) of the
Code (the "IQX Group")) or under which IQX or any member of the IQX Group has
any obligations (other than obligations to make current wage or salary payments)
in respect of any of the employees or former employees of IQX (including a
description of IQX's vacation policy) or their beneficiaries or which benefits
any of the employees or former employees of IQX (each individually, an "IQX
Employee Benefit Plan" and collectively, the "IQX Employee Benefit Plans").  IQX
has delivered to Buyer true and complete copies of, to the extent applicable,
all material documents, as such may have been amended to the date hereof,
embodying the IQX Employee Benefit Plans, all trust documents, all available
determination letters issued by the Internal Revenue Service (the "IRS"),
employee booklets, summary plan descriptions, insurance contracts, the most
recent compliance and nondiscrimination tests (if any), the most recent Form
5500 reports, standard COBRA forms and notices, any correspondence or inquiry by
the IRS or the Department of Labor, and any material employee communications, in
each case relating to any IQX Employee Benefit Plan.

          All IQX Employee Benefit Plans and all related insurance contracts,
trusts and funds have complied in form, operation and administration with their
respective provisions, any applicable provisions of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), the Code, and all other
applicable Laws.  All contributions to and payments from the IQX Employee
Benefit Plans which have been required to be made in accordance with the
provisions of the IQX Employee Benefit Plans and, where applicable, ERISA and
the Code have been made or are adequately accrued and reflected on the books and
records of IQX.  There are no unfunded Liabilities in respect of any such IQX
Employee Benefit Plan.  There has been no breach of fiduciary responsibility
with respect to any IQX Employee Benefit Plan to which ERISA is applicable which
could subject Buyer or IQX to any Liability under ERISA.

          No IQX Employee Benefit Plan is a multiemployer plan within the
meaning of Section 3(37) or Section 4001(a)(3) of ERISA (a "Multiemployer Plan")
or a multiple employer plan described in Sections 4063 and 4064 of ERISA.  No
member of the IQX Group has withdrawn from any IQX Employee Benefit Plan which
is a Multiemployer Plan or incurred any withdrawal liability to or under any
Multiemployer Plan.

          IQX does not have any Liability, and after the Closing, IQX will not
have any Liability, with respect to any Employee Benefit Plan which is not an
IQX Employee Benefit

                                       11
<PAGE>

Plan, whether as a result of delinquent contributions, distress terminations,
fraudulent transfers, failure to pay premiums to the Pension Benefit Guaranty
Corporation established pursuant to Subtitle A of Title IV of ERISA (the
"PBGC"), withdrawal liability or otherwise.

          No accumulated funding deficiency (as defined in Section 302 of ERISA
and Section 412 of the Code) exists nor has any funding waiver from the IRS been
received or requested with respect to any IQX Employee Benefit Plan and no
excise or other Tax is due or owing because of any failure to comply with the
minimum funding standards of the Code or ERISA with respect to any of such
plans.  To IQX's and the Majority Stockholder's knowledge, no IQX Employee
Benefit Plan is or is threatened to be under audit or investigation, and no
completed audit of any IQX Employee Benefit Plan has resulted in the imposition
of any Tax, fine or penalty.

          With respect to each IQX Employee Benefit Plan that purports to be a
qualified plan under Section 401(a) of the Code and exempt from federal income
tax under Section 501(a) of the Code (each a "Qualified Plan"), a determination
letter (or opinion or notification letter, if applicable) has been received from
the IRS that such plan is qualified under Section 401(a) of the Code and exempt
from federal income tax under Section 501(a) of the Code.  No Qualified Plan has
been amended since the date of the most recent such letter.  No member of the
IQX Group, nor any fiduciary of any Qualified Plan, nor any agent of any of the
foregoing, has done anything that would adversely affect the qualified status of
a Qualified Plan or the qualified status of any related trust.

          The present value of vested and nonvested accrued benefits under each
IQX Employee Benefit Plan that is a defined benefit plan within the meaning of
Section 3(35) of ERISA ("Defined Benefit Plan") does not exceed the present fair
market value of the assets of such plan, based on the actuarial assumptions and
methodology used for funding purposes (i) as set forth in such plan's most
recent actuarial report; (ii) as required by the PBGC on a termination basis;
and (iii) as set forth in FASB 87.  No Defined Benefit Plan has been terminated
or partially terminated since September 1, 1974.  No event has occurred and no
condition has existed that could constitute grounds under Section 4042 of ERISA
for termination of or appointment of a trustee to administer any IQX Employee
Benefit Plan which is a Defined Benefit Plan.  No member of the IQX Group has
transferred, in whole or in part, a Defined Benefit Plan to a corporation that
was at the time of transfer a member of a different controlled group of
corporations (within the meaning of Section 4001(a)(14) of ERISA) than the
transferor. IQX has no liability for any IQX Employee Benefit Plan that is not
accrued.

          No prohibited transaction (within the meaning of Section 406 of ERISA
and Section 4975 of the Code) with respect to any IQX Employee Benefit Plan
exists or has occurred that could subject IQX to any Liability or Tax under Part
5 of Title I of ERISA or Section 4975 of the Code. With the exception of the
requirements of Section 4980B of the Code and, except as set forth on Schedule
                                                                      --------
4.21, no post-retirement benefits are provided under any IQX Employee Benefit
----
Plan that is a welfare benefit plan as described in Section 3(1) of ERISA.
Except as set forth on Schedule 4.21, IQX does not have any early retirement
                       -------------
options or plans pursuant to which employees may choose to take early
retirement.  Except as set forth on Schedule 4.21, no shares of capital stock
                                    -------------
are reserved and/or eligible to be issued pursuant to any stock option, stock
appreciation, stock grant or similar plan of IQX.

product liability, workers' compensation, vehicular, business interruption or
other insurance held by or on behalf of IQX specifying the insurer, the policy

          4.23.  No Misrepresentations.  This Agreement (including the Schedules
                 ---------------------
hereto) does not contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements contained herein, in
light of the circumstances under which they were made, not misleading.

substances or wastes have been spilled, released, discharged or disposed of
from, on or under any property owned, leased or operated by IQX during its
occupancy. IQX has no Liability with respect to the clean-up or remediation of
any treatment, storage or disposal site or facility. IQX has delivered to Buyer
true and complete copies of any environmental and Hazardous Materials reports,
studies and assessments in its possession or control with respect to its leased
or operated real properties and/or any land adjacent thereto.

                 ---------
are used in, or required for the conduct of, its business as currently conducted

                 -------
thereof) has made any agreement or taken any other action causing anyone to
become entitled to a broker's fee or commission as a result of the transactions
contemplated hereby.

          4.29.  Disclosure Schedules.  All Schedules to this Agreement are
                 --------------------
integral parts of this Agreement. Nothing in a Schedule shall be deemed adequate
to disclose an exception to a representation or warranty made herein, unless the
Schedule identifies the exception with reasonable particularity and describes
the relevant facts in reasonable detail. IQX and the Majority Stockholder are
responsible for preparing and arranging the Schedules corresponding to the
numbered subsections contained in this Section 4.

its assets and properties and to carry on its business as presently conducted
and as presently contemplated. Buyer is duly qualified to transact business and
is in good standing in each jurisdiction in which the nature of its business or
the location of its property requires such qualification, except where the
failure to do so would not have a material adverse effect on its business,
operations, assets, prospects or condition (financial or otherwise). The
jurisdictions in which Buyer is qualified to do business are set forth on
Schedule 5.2 hereto.
------------

          5.3. Capitalization; Options; Shareholder Rights.  The authorized
               -------------------------------------------
capital stock of Buyer consists solely of 1,500,000 shares of common stock, $.01
par value per share ("Buyer Common Stock"), and 106,122 shares of preferred

except as provided in Section 630 of the BCL. Except as set forth on Schedule
                                                                     --------

any shareholder of Buyer may vote.  Except as set forth on Schedule 5.3, there
                                                           ------------
are, and on the Closing Date there will be, no preemptive rights, rights of
first refusal, voting rights, change of control or similar rights, anti-dilution

of the issuance by Buyer of the  Buyer Shares.

          5.4. Constituent Documents.  True and complete copies of Buyer's
               ---------------------

year ended on December

                                       15
<PAGE>

31, 1998 (the "1998 Financial Statements") and the unaudited consolidated
balance sheet (the "Buyer Interim Balance Sheet") and related statement of
income of Buyer as at and for the nine-month period ended on September 30, 1999

copies of all of which have been delivered to the Majority Stockholder and are
attached hereto as Schedule 5.5, present fairly in all material respects the
                   ------------
consolidated financial condition of Buyer as at the dates indicated therein and
the consolidated results of operations of Buyer for the periods covered thereby.
The Buyer Financial Statements have been prepared in accordance with GAAP
consistently applied, subject only in the case of the Buyer Interim Financial
Statements to ordinary year-end adjustments, none of which are material
individually or in the aggregate, and the absence of footnotes. The financial
books and records of Buyer are in all material respects complete and correct,
have been maintained in accordance with good business practices, and accurately
reflect the bases for the consolidated financial condition and results of
operations set forth in the Buyer Financial Statements.

          5.6. Absence of Changes.  Except as set forth on Schedule 5.6 hereto,
               ------------------                          ------------
since the date of the Buyer Interim Balance Sheet, there has not been (i) any
significant adverse change in the financial condition, results of operations,
assets or business of Buyer, (ii) any repayment of any indebtedness or any
borrowing of or agreement to borrow any money or any material Liabilities
incurred by Buyer, other than current Liabilities incurred in the ordinary
course of business, (iii) any material asset or property of Buyer made subject
to a Lien, (iv) any declaration or payment of dividends on, or other
distributions with respect to, or any direct or indirect redemption or
repurchase of, any shares of the capital stock of Buyer, (v) any issuance of any
stocks, bonds or other securities of Buyer, or any options, warrants or rights
or agreements or commitments to purchase or issue such securities (other than

any material tangible or intangible assets of Buyer, except with respect to
tangible assets effected in the ordinary course of business to persons not

the assets, property or business of Buyer, (ix) any purchase or other
acquisition of assets or property by Buyer other than in the ordinary course of
business, (x) any change in the accounting methods or practices followed by
Buyer, (xi) any operation of the business of Buyer outside of the ordinary
course of business and/or inconsistent with past practice, (xii) any waiver of
any valuable right of Buyer, or the cancellation or reduction of any material
debt or claim held by Buyer, or (xiii) except as provided by this Agreement, any
commitment or agreement (contingent or otherwise) to do any of the foregoing.

          5.7. Power and Authority.  Buyer has the requisite corporate power and
               -------------------
authority to execute and deliver this Agreement and all other agreements and
certificates referred to in or contemplated by this Agreement and to perform its
obligations hereunder and thereunder.  The execution, delivery and performance
of this Agreement and all other agreements and certificates referred to in or
contemplated by this Agreement have been duly authorized by all necessary
corporate action on the part of Buyer.  This Agreement has been duly executed
and delivered by Buyer and is (and such other agreements and certificates, when
executed and delivered, will be) the valid and binding obligations of Buyer
enforceable against Buyer in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy,

                                       16
<PAGE>

moratorium, insolvency, reorganization or other similar laws now or hereafter in
effect relating to or affecting creditors' rights generally and general
equitable principles (whether considered in a proceeding in equity or at law).

          5.8. Tax Matters.  Buyer has timely filed all Tax Returns that it has
               -----------
been required to file through the date hereof, and has timely paid in full all
Taxes which were due and payable by it through the date hereof. The provisions
for Taxes reflected on the Buyer Interim Balance Sheet are adequate to cover all
accrued and unpaid Taxes of Buyer for all periods ending on or before September
30, 1999, and nothing has occurred subsequent to that date to make such
provisions inadequate. Buyer has established and is maintaining current accruals
that are accurately reflected in the books and records of Buyer and are adequate
for the payment of any Taxes incurred but not yet due and payable with respect
to the property and operations of Buyer through the date hereof and will
establish and maintain adequate accruals for the payment of any such Taxes in
respect of the period through the Closing Date. No waivers or extensions of any
applicable statute of limitations for the assessment or collection of Taxes with
respect to any Tax Returns of Buyer are currently in effect or are currently
proposed. Buyer has collected or withheld and paid over to the proper
governmental or regulatory bodies all amounts required to be so collected or
withheld and paid over under all applicable Laws. No action, suit, proceeding,
investigation, audit, claim or assessment is presently pending or, to Buyer's
knowledge (as defined in Section 12.2 hereof), threatened with regard to any
Taxes that relate to Buyer for which Buyer is or could reasonably be expected to
be liable. There is no unresolved claim by a taxing authority in any
jurisdiction where Buyer does not anticipate to file Tax Returns that it is or
could reasonably be expected to be subject to taxation by such jurisdiction.
There are no Liens for Taxes (other than for Taxes not yet due and payable) upon
any assets or property of Buyer. The Stockholders acknowledge that the foregoing
representations and warranties made in this Section 5.8 do not apply in respect
of Accurate Components Inc. ("Accurate") or Market Trading Concepts Inc.
("Market Trading") (recently acquired, wholly-owned subsidiaries of Buyer). The
Stockholders further acknowledge that the representations and warranties made in
respect of Accurate and Market Trading as to Tax matters in that certain Stock
Purchase Agreement by and between Buyer, Accurate, Market Trading and Anthony
Arena, dated November 12, 1999, have been made available to the Stockholders for
their review and, to Buyer's knowledge, they are true and correct.

          Buyer (i) has not made any other election pursuant to the Code other
than elections that relate solely to matters of accounting, depreciation, or

          (b)   Notwithstanding anything to the contrary contained in Section

          10.3.  Notice to Indemnifying Party.  If any party (the "Indemnitee")

receives notice of any claim or the commencement of any action or proceeding
with respect to which the other party (or parties) is obligated to provide
indemnification (the "Indemnifying Party") pursuant to Sections 10.1 or 10.2
hereof, the Indemnitee shall give the Indemnifying Party written notice thereof
within a reasonable period of time following the Indemnitee's receipt of such
notice. Such notice shall describe the claim in reasonable detail and shall
indicate the amount (estimated if necessary) of the Losses that have been or may

of the asserted liability so requires) notify the Indemnitee of its intent to do
so, and the Indemnitee, shall reasonably cooperate, at the request and
reasonable expense of the Indemnifying Party, in the compromise of, or defense
against, such asserted liability. The Indemnifying Party will not be released
from any obligation to indemnify the Indemnitee hereunder with respect to a
claim without the prior written consent of the Indemnitee, unless the
Indemnifying Party delivers to the Indemnitee a duly executed agreement settling
or compromising such claim with no monetary liability to or injunctive relief
against the Indemnitee and a complete release of the Indemnitee with respect
thereto. The Indemnifying Party shall have the right, except as provided below
in this Section 10.3, to conduct and control the defense of any third-party
claim made for which it has been provided notice hereunder. All costs and fees
incurred with respect to any such claim will be borne by the Indemnifying Party.
The Indemnitee will have the right to participate, but not control, at its own
expense, the defense or settlement of any such claim; provided, that if the
                                                      --------
Indemnitee and the Indemnifying Party shall have conflicting claims or defenses,
the Indemnifying Party shall not have control of such conflicting claims or
defenses and the Indemnitee shall be entitled to appoint a separate counsel for
such claims and defenses at the cost and expense of the Indemnifying Party. If
the Indemnifying Party chooses to defend any claim, the Indemnitee shall make
available to the Indemnifying Party any books, records or other documents within
its control that are reasonably required for such defense.

$200,000, in which case only the excess over $200,000 shall be subject to
indemnification hereunder; provided, however, that the foregoing $200,000

by and between PartMiner, Inc., a New York corporation ("Buyer"), Accurate

          WHEREAS, the Shareholder is the beneficial and record owner of all of
the issued and outstanding capital stock of each of Accurate (the "Accurate
Shares") and Market Trading (the "Market Trading Shares"; and together with the
Accurate Shares, the "Shares"); and

          WHEREAS, the Shareholder desires to sell to Buyer, and Buyer desires
to purchase from the Shareholder, the Shares, all in the manner and subject to
the terms and conditions hereinafter set forth.

          NOW, THEREFORE, in consideration of the premises and the

parties hereby agree as follows:

          1.   SALE AND PURCHASE OF THE SHARES.
               -------------------------------

          1.1. Sale and Purchase.  On the Closing Date (as defined below in
               -----------------
Section 2.1) and subject to the terms and conditions contained herein, the

thereto, in proper form for transfer, free and clear of all Liens (as defined in
Section 12.2 hereof).

          2.   CLOSING.
               -------

          2.1. Time and Place.  The closing of the sale and purchase of the
               --------------
Shares (the "Closing") shall take place at the offices of Kirkpatrick & Lockhart
LLP, 1251 Avenue of the Americas, New York, New York 10020, at 10:00 a.m., local
time, on November 12, 1999, or at such other time, date and/or place as the
parties may mutually agree in writing. The date upon which the Closing shall
occur is hereinafter referred to as the "Closing Date."

          3.   CONSIDERATION FOR THE SHARES; PAYMENT; PURCHASE PRICE ADJUSTMENT.
               ----------------------------------------------------------------

          3.1. Amount of Purchase Price.  The aggregate purchase price for the
               ------------------------
Shares shall be the sum of (i) $7,400,000, subject to adjustment pursuant to
Section 3.3 hereof (the "Initial Purchase Price"); and (ii) any contingent
payments due and payable pursuant to Section 3.4 hereof (subsections (i) and
(ii) collectively, the "Purchase Price"). The portions of the Purchase Price
attributable to the Accurate Shares and to the Market Trading Shares shall be
agreed to by the Shareholder and Buyer as soon as practicable following the
Closing. Additionally, Buyer will pay to the Shareholder at Closing, interest at
a rate of seven (7%) percent per annum on the Closing Payment for the period
from and after September 30, 1999
<PAGE>

until October 31, 1999 (i.e., $38,191); provided, that the foregoing obligation
                                        --------
of Buyer to pay interest is subject to the obligations of the Shareholder and
the Companies not to take any actions or omit to take any actions in breach of
this Agreement that result in an unreasonable delay of the Closing. In the event
that the Closing has not occurred by December 1, 1999, and the parties at such
time still intend to seek to effect the transactions contemplated hereby, the
parties will meet in good faith to discuss the payment and amount of any future
additional interest.

          3.2. Payment at Closing. At Closing, Buyer shall pay to the
               ------------------
Shareholder the aggregate amount of $7,400,000 less the adjustments required
pursuant to Section 3.3 hereof (the "Closing Payment") for the Shares. The
Closing Payment (and interest due pursuant to Section 3.1 hereof) shall be paid
by Buyer's delivery to the Shareholder of a wire transfer of immediately
available funds to such account(s) as shall be designated by the Shareholder.

          3.3. Closing Payment Adjustment. (a) Buyer and the Shareholder agree
               --------------------------
that the Initial Purchase Price shall be decreased by $440,769 (the "Adjustment
Amount") reflecting the amount by which the Companies' "working capital" as of
September 30, 1999 was less than $3,500,000. As used in this Section 3.3,
                                                             -----------
"working capital" shall mean the Companies' current assets less their current
liabilities as derived from and based on, except as otherwise provided in
Schedule 3.3 hereto, the Interim Financial Statements. Interim Financial
------------
Statements shall mean the combined financial statements of the Companies as at
and for the nine-month period ended on September 30, 1999 prepared by the
Companies and audited by Buyer's independent auditors and which are attached as
part of Schedule 4.5 hereto. "Working capital" and the Adjustment Amount have
        ------------
been calculated as set forth on Schedule 3.3 hereto.
                                -------------------

          (b)  In addition, the (i) the advances to the Shareholder listed on
Schedule 3.3B (which have been included as a current asset for purposes of
-------------
Section 3.3(a)) and (ii) the outstanding balance on the mortgage loan to the
Shareholder listed on Schedule 3.3B (which balance has been included as a
                      -------------
current asset for purposes of Section 3.3(a)) shall be paid by the Shareholder
by deducting such amounts from the Initial Purchase Price. At the Closing, the
Companies and Buyer shall acknowledge that such advances and mortgage loan have
been paid in full and the Companies shall deliver a full satisfaction and
discharge of the mortgage listed on Schedule 3.3B.
                                    -------------

          3.4. Contingent Payment(s).
               ---------------------

          (a)  In addition to the Initial Purchase Price, Buyer will pay up to a
maximum of $1,700,000 as additional purchase price for the Shares, payable as,
and subject to the provisions, set forth below, and subject to the express
provisions of Section 3.4(e) hereof and the Arena Employment Agreement (as
defined in Section 7.14 hereof) (the "Contingent Payments"):

               (i)  If the Companies' 1999 EBIT (as defined below) shall equal
or exceed $1,500,000, Buyer shall pay to the Shareholder $510,000 (the "First
Contingent Payment") no later than March 31, 2000, following the completion of
the audit of Buyer's consolidated financial statements for the fiscal year ended
December 31, 1999 (the "1999 Audit"). As used herein, the "Companies' 1999 EBIT"
shall mean the earnings of the Companies before reduction for the payment of
interest and taxes for the fiscal year ended December 31, 1999. Such amount
shall be determined by Buyer in connection with the performance of the 1999
Audit and in a

                                       2
<PAGE>

manner consistent with the preparation and presentation of the income statement
included in the Interim Financial Statements; provided, that, for the period
                                              --------
following the Closing Date through December 31, 1999, the Companies shall be
treated for the purposes hereof on a stand-alone basis and any intercompany
transactions between Buyer and the Companies shall be eliminated.

               (ii)  If the condition set forth below in this subsection (ii) is
met, Buyer shall pay to the Shareholder $1,190,000 (the "Second Contingent
Payment") no later than March 31, 2001, following the completion of the audit of
Buyer's consolidated financial statements for the fiscal year ended December 31,
2000 (the "2000 Audit"):

               the aggregate "gross profit" (as defined below) generated by and
attributable to the Companies and the office (other than the contract
manufacturing division thereat) of Buyer currently located at Airport Corporate
Center, 630 Johnson Avenue, Bohemia, New York, or such other substitute location
at which Buyer may install the operations presently located thereat (other than
the contract manufacturing division thereat) in the future ("PartMiner Long
Island"), for Buyer's fiscal year 2000 ("2000 Gross Profit") shall equal or
exceed $9,751,580. As used herein, "gross profit" shall mean gross sales
(revenues), less sales returns, minus direct product cost (i.e., the cost of
                                                           ---
products paid by the Companies and/or Buyer). 2000 Gross Profit shall be
determined by Buyer in connection with the performance of the 2000 Audit and
shall be determined in good faith by Buyer and in a manner consistent with the
determination of "gross profit" based on the Interim Financial Statements, with
adjustments thereto consistent with those made in determining gross profit as
set forth on Schedule 3.4 hereto. Buyer represents that Schedule 3.4 fairly
             ------------                               ------------
presents the gross sales and direct product cost amounts for PartMiner Long
Island for the nine-month period ended September 30, 1999. A calculation of
"gross profit" for the nine months ended September 30, 1999 is set forth on
Schedule 3.4.
------------

          (b)  Buyer agrees that it will cause the 1999 Audit and 2000 Audit,
respectively, to be completed no later than ninety (90) days after the end of
the fiscal years ending on December 31, 1999 and December 31, 2000,
respectively. Buyer shall deliver to the Shareholder a copy of Buyer's audited
financial statements for fiscal years 1999 and 2000 when such become generally
available. Additionally, Buyer will pay to the Shareholder interest, at the rate
of 10% per annum, on any Contingent Payment which is payable to the Shareholder
hereunder which shall not have been paid on or before March 31, 2000 in the case
of the First Contingent Payment and March 31, 2001 in the case of the Second
Contingent Payment.

          (c)  (i)  Buyer shall provide to the Shareholder a certificate setting
forth in reasonable detail all of the determinations and calculations required
to be made pursuant to subsections (a)(i) and (ii) above, along with the
relevant financial information and statements from which they were derived and
copies of any accounting workpapers and other documentation regarding the
calculations.

               (ii) Buyer shall use its commercially best efforts to permit the
Companies and PartMiner Long Island operations to be conducted on a stand-alone
basis and in a manner which shall readily allow the determinations of 1999 EBIT
and 2000 Gross Profit to be made in accordance with subsections 3.4(a)(i) and
(ii) above. If, and to the extent that, Buyer cannot do the foregoing, Buyer
shall notify the Shareholder in writing and the 1999 EBIT and 2000 Gross Profit
shall be determined by Buyer, after making and giving effect to any adjustments
as Buyer shall

                                       3
<PAGE>

reasonably and equitably determine are necessary. Buyer further agrees that from
the Closing until January 1, 2001 Buyer shall not restrict, and shall not
prevent the Companies from, the hiring of employees who are dedicated to
generating sales for the Companies (or Buyer in respect of the portion of
Buyer's business which was operated by the Companies prior to the Closing) and
PartMiner Long Island such that the number of such dedicated employees is not
less than 110% of the number of such dedicated employees of the Companies and
PartMiner Long Island as of the date hereof (which number the parties hereby
agree is 41). Any material breach by Buyer of the provisions set forth in the
immediately preceding sentence shall entitle the Shareholder to the full amount
of the Second Contingent Payment whether or not the conditions to entitlement
therefor shall have been satisfied.

          (d)  The parties hereby acknowledge and agree that:

               (i)   any payment(s) due pursuant to this Section 3.4 shall be
made by Buyer's delivery to the Shareholder of a wire transfer of immediately
available funds;

               (ii)  except as provided in Section 3.4(e) hereof, the First
Contingent Payment and/or the Second Contingent Payment shall be payable if and
only if the conditions set forth in Section 3.4(a)(i), with respect to the First
Contingent Payment, and/or Section 3.4(a)(ii), with respect to the Second
Contingent Payment, are satisfied in full, and that the Shareholder is not, and
will not be, entitled to any partial or pro rata payments of the First
Contingent Payment and/or the Second Contingent Payment; and

               (iii) the Shareholder's entitlement to the First Contingent
Payment is not dependent on the Shareholder's entitlement to the Second
Contingent Payment and vice-versa, and the Shareholder's failure to become
entitled to either the First Contingent Payment or the Second Contingent Payment
shall not impair any entitlement to the other.

          (e)  Notwithstanding anything to the contrary in this Section 3.4
hereof, the Shareholder shall be entitled to be paid the Contingent Payments
(not already paid) immediately in the event that the Shareholder's employment
pursuant to the Arena Employment Agreement is terminated by the Company other
than for Cause (as defined in the Arena Employment Agreement) or by the
Shareholder for Good Reason (as defined in the Arena Employment Agreement) prior
to January 1, 2001, as provided in Section 5(e)(i) of the Arena Employment
Agreement (subject to Section 5(e)(i)(x) thereof).

          3.5. Dispute Resolution Procedures.  If any party disputes any
               -----------------------------
calculation or determination made pursuant to Section 3.4(a)(i) and/or (ii)
hereof or any financial statements or other information from which such
calculation or determination shall be derived, then within fifteen (15) calendar
days of his/its receipt of the challenged calculation or determination he/it
shall notify in writing the other party to this Agreement. Upon receipt of such
a notice, the parties hereby agree to negotiate in good faith for a period of
fifteen (15) calendar days to attempt to resolve such dispute. If the parties
are unable to resolve the dispute within such fifteen (15) calendar day period
then such dispute shall be promptly submitted to the American Arbitration
Association's New York City office for final and binding arbitration before
three arbitrators. Any such arbitration shall be resolved using the American
Arbitration Association's rules for expedited commercial arbitration. Each party
to the arbitration shall bear his/its own costs and expenses (including the fees
of counsel,

                                       4
<PAGE>

accountants and/or other experts). The fees and expenses of the arbitrator(s)
shall be borne by the party against whose position the arbitrators substantially
rules.

          4.   REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDER.  Subject to
               -------------------------------------------------
Section 10 hereof, the Shareholder hereby represents and warrants to Buyer as

          4.8. Tax Matters. Except as set forth on Schedule 4.8 hereto, the

Companies have timely filed all Tax Returns (as defined in Section 12.2 hereof),
that they have been required to file through September 30, 1999 except for Tax
Returns in respect of the accruals for Taxes payable on the Interim Financial
Statements, and have timely paid in full all Taxes (as defined in Section 12.2
hereof) which are due and payable by them pursuant to such Tax Returns. True and
complete copies of the Tax Returns of the Companies for the tax years ended
December 31, 1997 and December 31, 1998 have previously been delivered to Buyer.
To the Companies' and the Shareholder's knowledge, as of September 30, 1999, the

                                       7
<PAGE>

Statements. No waivers or extensions of any applicable statute of limitations

Companies are currently in effect or are currently proposed. The Companies have

presently pending or, to the Companies' and the Shareholder's knowledge (as
defined in Section 12.2 hereof), threatened with regard to any Taxes that relate
to the Companies for which either of the Companies is or could reasonably be
expected to be liable. There is no unresolved claim by a taxing authority in any
jurisdiction where either of the Companies does not anticipate to file Tax
Returns that it is or could reasonably be expected to be subject to taxation by
such jurisdiction. There are no Liens for Taxes (other than for Taxes not yet
due and payable) upon any assets or property of the Companies.

          Neither of the Companies (i) has elected to be treated as a

          (d)  Additional Disclosure.  The Companies and the Shareholder shall
               ---------------------

regardless of the form of the proposed transaction, concerning the potential or

any material assets of the Companies (other than inventory in the ordinary
course of business), or the merger, recapitalization, combination or

               ------------

immediately after the Closing, of those officers and directors of the Companies
as shall be requested by Buyer in writing delivered to the Shareholder on or
before the third business day prior to the Closing.

          (g)  Records.  On the Closing Date, the Shareholder shall deliver or

records and files stored on computer disks or tapes or any other storage medium
(collectively, "Records") in the possession or control of the Shareholder
relating to the Companies.

          (h)  Fees and Disbursements.  Buyer will pay the reasonable costs
               ----------------------
associated with the audit of the Interim Financial Statements, including the
reasonable costs of Brian Golub in connection therewith.  Except as provided in
the preceding sentence, Buyer and the Shareholder (and not the Companies) shall
pay their own costs and expenses, including the fees and disbursements of any

the preparation, execution, delivery and performance of this Agreement and the
transactions contemplated hereby, whether or not the transactions contemplated
hereby are consummated.

          (i)  Maintenance of Insurance.  The Companies shall maintain in full

force and effect their current insurance policies, unless simultaneously with

that provide coverage at levels and amounts equal to or greater than the
coverage under such current policies.

          (j)  Transfer Taxes. Notwithstanding anything to the contrary
               --------------
contained herein, the Shareholder and Buyer shall each be responsible for fifty
(50%) percent of all sales, use, transfer, real property transfer, documentary,
gains, stamp, duties, recording and similar Taxes and fees imposed upon or
incurred in connection with the transactions contemplated by this Agreement
(collectively, the "Transfer Taxes") and all necessary Tax Returns and other
documentation with respect to any Transfer Taxes shall be filed by the party
required to do so by applicable Law.

          (k)  Supplemental Disclosure.  The parties agree that, with respect to
               -----------------------
their representations and warranties made in this Agreement, they will have a
continuing obligation to promptly supplement and/or amend all Schedules to this
Agreement with respect to any matter hereafter arising or discovered which, if
existing or known at the date of this Agreement, would have been required to be
set forth or described in the Schedules to this Agreement.

          6.2. Post-Closing Covenants and Agreements.  Buyer and the Shareholder
               -------------------------------------
covenant and agree from and after the Closing Date as follows:

                                      19
<PAGE>

          (a)  Non-Interference.  The Shareholder shall not, at any time during
               ----------------

was employed or retained by, or affiliated with Buyer and/or, the Companies.

          (b)  Non-Compete.  The Shareholder shall not, at any time during the
               -----------
Restricted Period, directly or indirectly, own, manage, operate, join, control
or participate in the ownership, management, operation or control of, or be
employed or retained by, render services to, provide financing or advice to, or
otherwise be connected in any manner with any business that then competes with
any business of Buyer and/or the Companies; provided, that nothing in this
                                            --------
Section 6.2(b) shall prohibit the Shareholder (including his respective
affiliates and associates and any "group" (as such term is defined in the rules
promulgated under the Securities Exchange Act of 1934, as amended) of which such
person is a member) from acquiring up to three (3%) percent of any class of
outstanding equity securities of any corporation or other entity whose equity
securities are regularly traded on a national securities exchange or in the
"over-the-counter market."

          (c)  Confidentiality.  (i) The Shareholder acknowledges that all
               ---------------
information concerning each of the Companies' business, financial condition,
operations, strategies and prospects, including, but not limited to, customer,
supplier and distributor lists, trade secrets, plans, manufacturing techniques,
sales, marketing and expansion strategies, products, services, production,
development, technology and processes and all related technical information,
procurement and sales activities and procedures, promotion and pricing
techniques and credit and financial data relating to the Companies are valuable,
special and unique assets of the Companies (collectively, the "Confidential
Information"); provided, however, that Confidential Information shall not
               --------  -------
include any information that (x) is or shall become generally known to the
public (other than as a result of a breach of this Agreement by the
Shareholder); (y) shall become available to a disclosing party from an
unaffiliated third party; provided, that such party shall not be under any
                          --------
obligation of confidentiality known to the Shareholder to another party to this
Agreement; or (z) is required by law or court order to be disclosed; provided,
                                                                     --------
that the disclosing party shall give all other parties to this Agreement prompt
written notice of any such legal or judicial process requiring disclosure of
Confidential Information and shall reasonably cooperate with the other party, at
such other party's expense, in any lawful action which such other party desires
to take to limit the disclosure required by such legal or judicial process, and
shall permit any other party to this Agreement to attempt, by appropriate legal
means, to limit and/or delay such disclosure.

          The Shareholder hereby acknowledges and agrees that during such time
as he was a shareholder of the Companies and thereafter during his employment by
Buyer, any and all United States and/or foreign patents, patent applications,
service marks, inventions, discoveries, innovations, improvements, trade secrets
and secret processes, whether or not patentable, which

                                      20
<PAGE>

he may have conceived, developed or made, or may conceive, develop or make,
either alone or in conjunction with others, and which were or will be used in or
developed for the business of the Companies or Buyer (collectively "Developed
Property"), have been and shall be fully disclosed to Buyer, and are and shall
be the sole and exclusive property of Buyer, whether or not disclosed, as
against the Shareholder. The Shareholder hereby unconditionally and irrevocably
assigns to Buyer any and all right, title and interest in and to such Developed
Property and hereby irrevocably and unconditionally waives any rights in or to
such Developed Property.

               (ii)  Buyer agrees that neither Buyer nor any of its affiliates
shall (until after the Closing) disclose any Confidential Information to any
person or make use of or exploit any Confidential Information for its own
purposes or for the benefit of any person other than to its accountants,
attorneys or other representatives to the extent reasonably necessary to
complete its due diligence review of the Companies' businesses and to document
and consummate the transactions contemplated by this Agreement; provided, that
                                                                --------
Buyer shall notify such accountants, attorneys or other representatives of
Buyer's obligations under the terms of this Section 6.2(c)(ii) and Buyer shall
be responsible for its accountants, attorneys or other representatives
compliance with the provisions of this Section 6.2(c)(ii). If this Agreement is
terminated pursuant to Section 11 hereof, Buyer shall return all Confidential
Information and all copies thereof to the Companies, destroy any extracts or
notes derived therefrom, and shall not make use of any Confidential Information
for its own purposes or for the benefit of any person, except that Buyer may
retain copies of the Confidential Information, subject to its confidentiality
obligations hereunder, which are required to be retained to support any claim
that shall have arisen or may reasonably be expected to arise out of this
Agreement or the transactions contemplated hereby.

               (iii) The Shareholder acknowledges and agrees that all
Confidential Information is the exclusive property of the Companies and, after
the Closing, of Buyer and the Companies. The Shareholder shall not disclose,
directly or indirectly, Confidential Information to any person or, directly or
indirectly, make use of or exploit for his own purposes or the benefit of any
other person (except as an officer, director or employee of Buyer or its
affiliates) any Confidential Information.

          (d)  Equitable Relief.  Each of Buyer and the Shareholder acknowledges
               ----------------
and agrees that any breach by Buyer or the Shareholder of any provision of
Sections 6.1(e), 6.2(a), (b) or (c) hereof would cause irreparable injury and
could not be remedied solely by monetary damages. In the event of a breach or
threatened breach of any of such provisions, any non-breaching party shall be
entitled to equitable relief, including, without limitation, injunctive relief
and specific performance, without proof of actual damages. Such relief shall be
in addition to any other remedies available at law or in equity. In the event
the Company fails to pay to the Shareholder any Contingent Payments, subject to
Section 10.6(a) hereof, when due in accordance with this Agreement, which
failure is not cured within fifteen (15) days after written notice from the
Shareholder, the provisions of Section 6.2(a) and (b) shall terminate; provided,
                                                                       --------
however, that to the extent there is any dispute as to whether any Contingent
-------
Payment is due, such payment shall not be deemed to be due until fifteen (15)
days after the issuance of a final, non-appealable judgment of a court of
competent jurisdiction or a final and binding arbitration ruling pursuant to
Section 3.5 hereof as to whether such Contingent Payment is due.

                                      21
<PAGE>

          (e)  The Companies' Employees.  Buyer agrees that as soon as
               ------------------------
practicable after the Closing it shall determine in good faith whether to adjust
the compensation of the employees of the Companies who shall remain employees of
the Companies or become employees of Buyer based upon such factors as it shall
deem reasonably appropriate, including, without limitation, prevailing market
rates of compensation and Buyer's then existing compensation for similarly
situated employees.  Buyer does not presently believe and it is not Buyer's
present intention to alter in any material respect the compensation of such
employees of the Companies following the Closing.  Notwithstanding anything
herein to the contrary, Buyer agrees that with respect to the four senior
employees of the Companies listed on Exhibit B hereto and the five (5) top
                                     ---------
performing sales representatives of the Companies listed on Exhibit A hereto,
                                                            ---------
after the Closing and through December 31, 2000 (so long as such persons shall
remain employees of the Companies) each such employee will be paid a salary and
provided a commission plan which in the aggregate are substantially equivalent
to the aggregate salary and commission plan provided by the Companies
immediately prior to the Closing, all of which salaries and commission plans
have been disclosed in writing to Buyer prior to the Closing. Buyer recognizes
that the Shareholder believes that such agreement is material to his ability to
earn the Contingent Payments. In consideration of certain non-compete agreements
to be entered into by Buyer and such senior employees (in form and substance to
be reasonably and mutually agreed to as soon as practicable following the
Closing), Buyer agrees that the senior employees of the Companies listed on
Exhibit B hereto shall be provided, for a period of up to six (6) months
---------
following the termination of their employment, if within one year following the
Closing Date, by Buyer or the Companies for any reason other than "cause" (as
such term is generally defined and used under New York contract law), with the
base salary and general employee benefits to which they were entitled at the
time of their termination. Buyer agrees that all employees of the Companies who
shall remain employees of the Companies or become employees of Buyer shall be
entitled to participate in the employee benefits and plans, including, without
limitation, stock option plans, provided by Buyer to its employees generally
subject to the terms thereof and that such employees shall be given credit for
their years of prior service with the Companies in connection with the provision
of such benefits and any preexisting conditions or limitations with respect to
medical and health benefits shall be waived (or Buyer shall maintain in effect
the Companies' present medical and health insurance plans). Notwithstanding
anything contained herein, nothing in this Agreement shall confer, or shall be
construed to confer, upon any employee of the Companies (other than the
Shareholder) who shall become an employee of Buyer any right to the continuance
of employment with Buyer nor shall anything contained in this Agreement limit in
any manner the right of Buyer to terminate any such employee at any time or for
any reason.

representations and warranties contained in the first and third sentences of

Companies, the Shareholder shall be entitled to, and Buyer shall pay and
reimburse the Shareholder for, (A) all reasonable attorneys' fees and expenses
incurred in connection with such action or proceeding and the defense thereof
and (B) any other Losses incurred by the Shareholder in connection therewith;

provided, however, that Buyer shall be required to so indemnify the Shareholder

only if (x) the Shareholder, in respect to the actions or omissions at issue in
such action or proceeding, acted in good faith and for a purpose which he
reasonably believed to be in the best interests of the Companies, and had no
reasonable cause to believe that his conduct was unlawful and (y) the actions or

                 ----------------------------
receives notice of any claim or the commencement of any action or proceeding
with respect to which the other party (or parties) is obligated to provide
indemnification (the "Indemnifying Party") pursuant to Sections 10.1 or 10.2
hereof, the Indemnitee shall give the Indemnifying Party written notice thereof
within a reasonable period of time following the Indemnitee's receipt of such
notice.  Such notice shall describe the claim in reasonable detail and shall
indicate the amount (estimated if necessary) of the Losses that have been or may
be sustained by the Indemnitee.  The Indemnifying Party may, subject to the
other provisions of this Section 10.3, compromise or defend, at such
Indemnifying Party's own expense and by such Indemnifying

Indemnitee of its intent to do so, and the Indemnitee, shall reasonably
cooperate, at the request and reasonable expense of the Indemnifying Party, in
the compromise of, or defense against, such asserted liability. The Indemnifying
Party will not be released from any obligation to indemnify the Indemnitee

Indemnitee, unless the Indemnifying Party delivers to the Indemnitee a duly
executed agreement settling or compromising such claim with no monetary
liability to or injunctive relief against the Indemnitee and a complete release
of the Indemnitee with respect thereto. The Indemnifying Party shall have the
right, except as provided below in this Section 10.3, to conduct and control the
defense of any third-party claim made for which it has been provided notice
hereunder. All costs and fees incurred with respect to any such claim will be
borne by the Indemnifying Party. The Indemnitee will have the right to
participate, but not control, at its own expense, the defense or settlement of
any such claim; provided, that if the Indemnitee and the Indemnifying Party
                --------
shall have conflicting claims or defenses, the Indemnifying Party shall not have
control of such conflicting claims or defenses and the Indemnitee shall be
entitled to appoint a separate counsel for such claims and defenses at the cost
and expense of the Indemnifying Party. If the Indemnifying Party chooses to
defend any claim, the Indemnitee shall make available to the Indemnifying Party
any books, records or other documents within its control that are reasonably
required for such defense.

          10.4.  Limitation on Indemnification.  Notwithstanding anything to the
                 -----------------------------

(iii) and 10.2(b) hereof, shall not exceed $2,000,000 and (B) the aggregate
liability of Buyer for any and all Losses incurred by the Shareholder (and all

Indemnitees shall exceed $200,000, in which case only the excess over $200,000

reduce any Contingent Payment(s) payable by it pursuant to Section 3.4 hereof by
all amounts due in respect of Losses to which it is entitled to indemnification
under Section 10.1 hereof; provided, that if such Losses exceed such Contingent
                           --------
Payment(s), Buyer shall remain entitled to indemnification hereunder for such
excess amount subject to Section 10.4 hereof.  Buyer shall additionally be
entitled to offset and reduce any amounts owed to the Shareholder hereunder by
all amounts due in respect of Losses to which Buyer (or any related Indemnitee)

binding determination of three jointly selected arbitrators or a court of

shall be decreased if and to the extent of any insurance proceeds actually
received by the Indemnitee directly in respect of the Losses giving rise to such
indemnification payment(s).

          (d) Subject to Section 10.2(b) hereof, the Shareholder hereby
irrevocably waives any and all rights to indemnification from the Companies in
his capacities as a director and/or officer of the Companies to which he would
otherwise have been entitled for all periods

                 ----------------
Buyer acknowledges and agrees that from and after the Closing that (absent
fraud) the Shareholder's, the Companies' and Buyer's sole exclusive remedy (at
