ITEM 2. Acquisitions of Assets.


On January 13, 2000, EarthWeb Inc. ("EarthWeb") entered into a Securities
Purchase Agreement (the "Purchase Agreement") with Measure Up, Inc. ("Measure
Up"), Kevin R. Brice and Robert M. M. Holtackers (collectively, "Seller"). Also
on that date, EarthWeb entered into Option Holder Purchase Agreements with each
of Kenneth B. Williams, Jeffrey W. Adkisson, Jack R. Freeman, Melissa S. Stover,
Scott E. Hall, Chad A. Dorn and Deanne Brown (collectively, the "Option Holder
Agreements" and, together with the Purchase Agreement, the "Agreements").
Pursuant to the Agreements, EarthWeb acquired all of the capital stock of
Measure Up on February 8, 2000. A copy of the Purchase Agreement is attached as
Exhibit 2.1 and copies of each of the Option Holder Agreements are attached
hereto as Exhibit 10.1.

The consideration paid by EarthWeb to acquire all of the capital stock of
Measure Up consisted of (a) $10 million in cash, which was paid at closing, (b)
two additional payments payable in May 2000 and August 2000, of $2.5 million
each, $2.3 million of which is in the form of restricted stock and $0.2 million
in the form of cash, and (c) additional future "earnout" payments based on
performance of the business in the form of cash or restricted EarthWeb common
stock or both with an aggregate value of up to $10 million, of which such
amounts are payable over a period of three years based on achievement of certain
revenue targets. Under the terms of the Agreements and a related escrow
agreement, 134,127 restricted shares of stock (subject to future adjustments)
have been placed in escrow to secure the $2.3 million payable and an additional
58,207 restricted shares (also subject to future adjustments) have been placed
in escrow to secure potential obligations contingent on the achievement of
certain future performance targets. The amount of consideration was reached
through arm's length negotiations and was funded by the proceeds of EarthWeb's
January 2000 convertible debt offering and through the issuance of EarthWeb's
restricted common stock.

The acquisition of Measure Up will be accounted for as a purchase. The purchase
price will be allocated to assets based on their fair values, with the excess
allocated to goodwill. Results of Measure Up will be included with those of
EarthWeb for periods subsequent to the date of acquisition.

Measure Up provides online certification preparation for Microsoft, A+, Novell
and Cisco.

In accordance with a registration rights agreement executed and delivered as
part of the acquisition, EarthWeb granted certain rights to Kevin R. Brice and
Robert M. M. Holtackers with respect to the registration of EarthWeb common
stock. A copy of such registration rights agreement is attached as Exhibit 4.1.

ITEM 7. FINANCIAL STATEMENTS AND PRO FORMA FINANCIAL INFORMATION.


(a) Financial Statements of Business Acquired.


                       Report of Independent Accountants


To the Board of Directors of
MeasureUp, Inc.:

In our opinion, the accompanying balance sheets and the related statements of
operations, of stockholders' deficit and of cash flows present fairly, in all
material respects, the financial position of MeasureUp, Inc. at December 31,
1998 and 1997, and the results of their operations and their cash flows for the
year ended December 31, 1998 and for the period from August 25, 1997 (inception)
to December 31, 1997 in conformity with accounting principles generally accepted
in the United States. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with auditing standards generally accepted in the
United States, which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

1.   The Company

     MeasureUp, Inc. (the "Company"), founded on August 25, 1997 (inception),
     provides training and assessment preparation products for information
     technology ("IT") professional certifications. The Company uses a testing
     system to deploy individually licensed preparation products over the
     Internet to a worldwide channel of distributors and individuals. In
     addition to single user licenses for preparation products, MeasureUp offers
     private labeling and multi-user licensing. MeasureUp is headquartered in
     Atlanta, Georgia and its customers are located throughout the United
     States. The Company was considered a development stage enterprise for the
     period from inception through December 31, 1997 as substantially all of the
     Company's efforts through December 31, 1997 were devoted to organizing the
     Company, establishing its management team, raising capital, developing its
     website, and building its sales and marketing function.


2.   Significant Accounting Policies

     Revenue recognition
     Revenue from sales to certification preparation resellers and direct sales
     is recognized ratably over the performance period, which is the period the
     Company has agreed to allow usage and maintain its website. Deferred
     revenue represents amounts received prior to being earned over the
     performance period. Revenue from sales of test preparation content on CD-
     ROM is recognized when the product is shipped. For software license sales
     where no significant contractual obligations remain outstanding, the
     Company recognizes revenue upon shipment.

     Concentration of credit risk
     The Company maintains allowances for credit losses and such losses have
     been within management's expectations. Four customers accounted for
     approximately 64% of the gross accounts receivable balance at December 31,
     1998. One customer accounted for approximately 17% of gross revenues for
     the year ended December 31, 1998.

     Financial instruments
     The recorded amounts of financial instruments approximate their fair value.

     Fixed assets
     Fixed assets are stated at cost less accumulated depreciation. Depreciation
     of computer equipment, furniture and fixtures, and office equipment is
     provided for by the straight-line method over the estimated useful life of
     three years. Repairs and maintenance costs are charged to operations in the
     periods incurred.

     Income taxes
     The Company qualified as a Subchapter S corporation in the U.S. for federal
     and state income tax purposes from inception through June 30, 1999.
     Accordingly, no provision has been made for income tax purposes during
     those periods. Individual stockholders report their share of the U.S.
     taxable income or loss on their respective individual income tax returns.
     Such U.S. taxable income or loss allocated to the stockholders differs from
     book income primarily due to revenue recognition. Effective July 1, 1999,
     the Company elected Subchapter C corporation status.

     Risks and uncertainties
     The Company has a limited operating history and its prospects are subject
     to the risks, expense and uncertainties frequently encountered by companies
     in the new and rapidly evolving markets for Internet products and services.
     These risks include the failure to develop and extend the Company's online
     products, the rejection of the Company's products by Web consumers and
     vendors, the inability of the Company to maintain and increase the levels
     of use of its online products, as well as other risks and uncertainties. In
     the event that the Company does not successfully implement its business
     plan, certain assets may not be recoverable.

     Use of estimates
     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amount of assets and liabilities,
     disclosure of contingent assets and liabilities at the date of the
     financial statements and reported amounts of revenues and expense during
     the reporting period. Actual results could differ from these estimates. The
     Company's significant estimates include the useful lives of fixed assets
     and the accounts receivable allowance for doubtful accounts.

     Long lived assets
     The carrying value of assets is reviewed on a regular basis for the
     existence of facts or circumstances, both internally and externally, that
     suggest impairment. To date, no such impairment has been indicated. Should
     there be an impairment in the future, the Company will determine the
     impairment based on comparison of recorded amounts to the expected future
     cash flows from the impaired assets. The cash flow estimates will contain
     management's best estimates using appropriate and customary assumptions and
     projections at the time.

     Interim financial information (unaudited)
     Interim financial statements have been prepared on a basis consistent with
     the preparation of annual financial statements and reflect all adjustments
     necessary for a fair presentation of the information for the periods
     presented.

     Stock split
     On June 30, 1999 the Company authorized and implemented a stock split at
     1.95668-for-1, and on October 12, 1999 the Company authorized and
     implemented a 10-for-1 stock split. An amount equal to the par value of the
     common stock issued was transferred from additional paid-in capital to the
     common stock account. All references to the numbers of shares of common
     stock, except shares authorized, have been adjusted in the financial
     statements and related footnotes to reflect the stock splits on a
     retroactive basis.

     Comprehensive income
     The Company adopted the provisions of SFAS No. 130, "Reporting
     Comprehensive Income" in 1998. SFAS No. 130 establishes standards for
     reporting comprehensive income and its components in financial statements.
     Comprehensive income, as defined, includes all changes in equity (net
     assets) during a period from non-owner sources. To date, the Company has
     not had any transactions that are required to be reported in comprehensive
     income.

     These shares were subsequently issued on July 1, 1999. The Company applied
     Accounting Principles Board No. 25, "Accounting for Stock Issued to
     Employees" and related interpretations in accounting for the issuance of
     this stock.

     For the year ended December 31, 1998 and for the period from inception to
     December 31, 1997, the majority shareholder contributed $109,165 and
     $134,586, respectively.

     On October 12, 1999, the Company amended the articles of incorporation to
     increase the number of authorized shares of $.01 par value common stock
     from 100,000 to 2,500,000.

     Stock option plan
     In August 1998, the Company implemented its Stock Incentive Plan (the
     "Plan") under which incentive stock options or non-qualified stock options
     to purchase the Company's common stock, par value $.01 per share, may be
     granted to eligible employees. A summary of the status of the Plan at
     December 31, 1998 and changes during the year then ended is presented
     below:

MEASUREUP, INC.
Notes to Financial Statements
- --------------------------------------------------------------------------------

     Options granted are either immediately vested or vest over a period of four
     years; however, the remaining unvested options automatically vest upon a
     substantial change in ownership of the Company, which is defined as either
     50% of the Company's stock or 80% of the Company's assets. At December 31,
     1998, the Company had reserved 50,000 shares of common stock for the
     exercise of options.

     The option plan also provides for the issuance of stock appreciation rights
     and restricted stock awards under which shares of common stock may be
     issued to eligible employees. No such awards have been made.

     Stock-based compensation
     The Company applies Accounting Principles Board Opinion No. 25, "Accounting
     for Stock-Issued to Employees" and related interpretations in accounting
     for its stock option issuances. The Company has adopted the disclosure-only
     provisions of SFAS No. 123, "Accounting for Stock-Based Compensation." Had
     compensation cost for the Company's stock option issuances been determined
     based on the fair value at the grant date for awards in 1998 consistent
     with the provisions of SFAS No. 123, the Company's net loss would have been
     adjusted to the pro forma amount indicated below.

                                                            December 31,
                                                                1998

     Net loss - as reported                                 $   (421,302)

     Net loss - pro forma                                       (423,221)

     The fair value of each option grant is estimated on the date of the grant
     using the "Black-Scholes option-pricing model" with the following weighted
     average assumptions used for the grant for the year ended December 31,
     1998: zero dividend yield; no volatility; a weighted average risk-free
     interest rate of 5.14%; and expected lives of 4 years.


7.   Subsequent Events

     On March 24, 1999, the principal stockholder loaned to the Company $30,000
     for the purpose of providing to the Company additional operating funds. It
     is the Company's intent to make full payment on this obligation by December
     31, 2000. The liability has been classified in Other current liabilities.

     On October 31, 1999, the Company entered into a letter of intent with a
     provider of Internet-based online services to the IT industry for the
     acquisition of all of the common stock of the Company from its
     stockholders. The transaction is expected to be completed in early 2000.

(b)  Unaudited Pro Forma Condensed Consolidated Financial Information

The valuations and other studies required to determine the fair value of the
Measure Up assets acquired and liabilities assumed have not been performed and,
accordingly, the related adjustments reflected in the unaudited pro forma
condensed consolidated financial information are preliminary and subject to
further revisions and adjustments. For purposes of this presentation, the
carrying amounts of the Measure Up net assets acquired were assumed to
approximate fair value. Therefore, the excess of purchase price over the
historical net book value of the net assets of Measure Up has been classified on
the pro forma balance sheet as "Goodwill and Intangibles". The final valuation
could result in different allocations of the purchase price compared to the
amounts presented in the following pro forma information, resulting in
corresponding changes in depreciation and amortization amounts.

The unaudited pro forma condensed consolidated statements of operations for the
year ended December 31, 1998 and the nine months ended September 30, 1999 give
effect to the acquisition of Measure Up as if the transaction occurred on
January 1, 1998 and are based on the historical results of operations of
EarthWeb and Measure Up. The unaudited pro forma condensed consolidated balance
sheet and the unaudited pro forma condensed consolidated statements of
operations and the accompanying notes should be read in conjunction with the
historical financial statements of EarthWeb and Measure Up and notes thereto.

The unaudited pro forma condensed consolidated financial statements are based on
the preliminary estimates and assumptions set forth in the notes to these
statements that have been made solely for the purposes of developing this pro
forma information. The unaudited pro forma condensed consolidated financial
statements are not necessarily an indication of the results that would have been
achieved had this transaction been consummated as of the dates indicated or that
may be achieved in the future. In addition, the Unaudited Pro Forma Condensed
Consolidated Financial Information does not include the pro forma impact of the
acquisitions of D&L Online, Inc. and Micro House International, Inc. which was
acquired in February 1999 and March 1999 respectively. The impact of these
acquisitions was presented in EarthWeb's forms 8-K/A filed on April 15, 1999 and
May 26, 1999, respectively.

1(c) Adjustment to record approximately $750,000 of transaction costs incurred
with the acquisition.

1(d) Adjusted to reflect the issuance of an estimated 134,127 shares of common
stock valued at $4,619,000 payable in May 2000 and August 2000 (based on the
average stock price from February 1, 2000 through February 7, 2000).

The pro forma adjustments to the unaudited pro forma condensed consolidated
statements of operations, assuming the acquisition occurred on January 1, 1998
are as follows:

2(a) Adjustment to amortization to reflect the amortization of goodwill and
intangible assets of approximately $3.9 million and $2.9 million for the year
ended December 31, 1998 and nine months ended September 30, 1999, respectively,
resulting from the acquisition of Measure Up over an approximate four year
period, the expected period of benefit.

2(b) Adjustment of weighted average shares of common stock outstanding of
134,127 used in computing basic and diluted net loss per share to reflect the
issuance of 134,127 shares as of January 1, 1998.

2(c) The supplemental pro forma net loss per share amount is computed by using
the sum of the weighted average number of shares of common stock and the
2,439,833 shares of common stock issued in November 1988 upon conversion of
preferred stock as if it had been converted on January 1, 1998.

                         SECURITIES PURCHASE AGREEMENT

     This Securities Purchase Agreement (this "Agreement") is made this 13th day
of January, 2000, by and between EarthWeb Inc., a Delaware corporation
("Buyer"), Measure Up, Inc., a Georgia corporation ("Target"), Kevin R. Brice
and Robert M. M. Holtackers (collectively, "Seller").

                               R E C I T A L S:

     WHEREAS, Buyer desires to purchase, and Seller desires to sell, assign and
transfer to Buyer all of the capital stock in Target which any Seller owns or in
which a Seller has an interest, all on the terms and subject to the conditions
hereinafter set forth. All of the securities of Target, which are to be
purchased by Buyer pursuant to this Agreement, are collectively referred to
hereinafter as the "Securities"; and

     WHEREAS, it is a condition to the closing of this Agreement that Kenneth B.
Williams, Jeffrey W. Adkisson, Jack R. Freeman, Melissa S. Stover, Scott E.
Hall, Chad A. Dorn and Deanne Brown (each, an "Option Holder" and, collectively,
the "Option Holders") each will enter into an agreement with Buyer whereby each
Option Holder will sell, assign and transfer to Buyer all shares issuable upon
conversion of their options (the "Options") held by such Option Holder (each
such agreement, an "Option Holder Purchase Agreement").

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

                                   SECTION 1

                                    Closing

     1.1.    Closing Date.  The closing (the "Closing") of the transactions
             ------------
contemplated hereby shall be held at the offices of counsel to Buyer, Morrison &
Foerster LLP, 1290 Avenue of the Americas, 40th Floor, New York, New York 10104-
0050 and shall take place no later than sixty (60) days from the date of this
Agreement (the "Termination Date") or such other date and place as may be
mutually agreed upon by the parties (the "Closing Date").

     1.2.    Purchase and Sale of Securities.  On the terms and subject to the
             -------------------------------
conditions herein set forth, Buyer shall purchase from Seller all of the
Securities, as of the Closing Date.

     1.3.    Method of Conveyance.
             --------------------

             (a) The sale, transfer, conveyance, assignment and delivery by
Seller of the Securities to Buyer shall be effected on the Closing Date by the
delivery of the Securities and

                                       1
<PAGE>

execution of customary stock powers, duly guaranteed, and other appropriate
documents by Seller, as appropriate (collectively, the "Instruments of
Conveyance"), to Buyer.

             (b) At the Closing, good and valid title to all of the Securities
shall be transferred, conveyed, assigned and delivered by Seller to Buyer
pursuant to this Agreement and the Instruments of Conveyance, free and clear of
any and all Liens (as defined below). For the purposes of this Agreement, the
term "Lien" shall mean any pledge, security interest, encumbrance, lien or
charge of any kind whatsoever.

             (c) At the Closing, Seller shall cause Target to provide Buyer with
an estoppel certificate signed by each creditor (excluding trade creditors) to
which Target owes at least $10,000 (the "Third Party Funded Debt"), each
certificate indicating the balance due on the Third Party Funded Debt, including
any accrued and unpaid interest thereon, as of the end of the preceding month,
together with a per diem interest rate during the month in which the Closing
occurs.

             (d) At the Closing, Seller shall cause Target to provide Buyer with
a certificate signed by Target indicating the balance of trade accounts payable
("Trade Accounts Payable") due to third parties indicated on Schedule 1.3(d)
hereto, including any accrued and unpaid interest thereon, as of the end of the
preceding month.

     1.4.    No Assumed Obligations.  Pursuant to this Agreement, Buyer does not
             ----------------------
assume any of the liabilities or obligations of Target whether absolute,
accrued, contingent or otherwise, whenever incurred; provided, that Buyer
understands that the assets of Target are subject to existing liabilities and
obligations.

     1.5.    Purchase Price.
             --------------

     The aggregate purchase price for the Securities (the "Purchase Price") is
up to a dollar amount determined by multiplying Twenty Five Million Dollars
($25,000,000) by the percentage ownership by Seller of the Target on a fully
diluted basis (including the Options) (and allocated among persons comprising
Seller as set forth in Exhibit A hereto; the percentage ownership by Seller of
the Target on a fully diluted basis is referred to herein as the "Seller
Percentage"):

             (a) at the Closing, Buyer shall pay, in the aggregate, Four Million
Dollars ($4,000,000) multiplied by the Seller Percentage in cash (the "Closing
Date Cash Payment") to Seller, the amounts set next to the name of each such
Seller on Schedule 1.5(a) hereto;

             (b) at the Closing, Buyer shall deliver to each party comprising
Seller a pro rata portion (based on the portion of the Purchase Price to be
received by such party as set forth in Exhibit A hereto ("Pro Rata")) of
registered shares of Buyer's common stock, $.01 par value ("Buyer Common
Stock"), having an aggregate value of Six Million Dollars ($6,000,000)
multiplied by the Seller Percentage (the "Closing Date Block of Buyer Common
Stock"), such number of shares to be determined by taking the average of the
closing prices of Buyer Common Stock on the Nasdaq National Market (the "Average

particular fact or other matter if such individual is actually aware of such
fact or other matter or such individual should or could reasonably be expected

such corporation, or, in the case of the Target, Kevin Brice and Ken Williams,

and transactions in the ordinary course of business since the date of the
September 1999 Financial Statements in accordance with past custom and practice.

             (e) Target does not own stock of any other corporation meeting the
requirements of Code Section 1504(a)(2), and Target is not liable for the Tax of
any other person or entity under Treasury Regulation 1.1502-6 (or any similar
provision of state, local or foreign law) as transferee or successor, by
contract, or otherwise.  Target is not and has not been a United States real
property holding corporation within the meaning of Code Section 897 and Buyer is
not required to withhold on the purchase of the stock of Target by reason of
Section 1445 of the Code.  Target is not a "consenting corporation" under
Section 341(f) of the Code.  Target has not entered into any compensatory
agreements with respect to the performance of services which payment thereunder
would result in a nondeductible expense to Target pursuant to 280G of the Code.
Target has not been the distributing corporation with respect to a transaction
described in Section 355 of the Code.  Target has not agreed, nor is it required
to make, any adjustment under Code Section 481(a) by reason of a change in
accounting method or otherwise.

Target's basis in its assets, Target's current and accumulated earnings and
profits, Target's tax carryovers and tax elections made by Target.  Target has
no net operating losses or other tax attributes presently subject to limitation
under Code Sections 382, 383 or 384.  Target has furnished to Buyer true and
complete copies of all federal and state income or franchise Tax returns for all

hereby or by the Transaction Documents, or that any such License would not be
renewed in the ordinary course.

employee. The Target has determined that the transactions contemplated hereby do
not constitute a change of control for purposes of any such agreement, plan,

change such determination, provided that the foregoing shall not apply to the
accelerated vesting of any stock options.

          (e)  Each Target Employee Benefit Plan that is intended to qualify
under Section 401 of the Code, and each trust maintained pursuant thereto, has
been determined to be exempt from federal income taxation under Section 501 of
the Code by the Internal Revenue Service (the "IRS"), and, to Target's
knowledge, nothing has occurred with respect to the operation or organization of
any such Target Employee Benefit Plan that would cause the loss of such
qualification or exemption or the imposition of any material liability, penalty
or tax under ERISA or the Code.

          (f)  (i)  All contributions (including all employer contributions and
employee salary reduction contributions) required to have been made under any of
Target Employee Benefit Plans to any funds or trusts established thereunder or

tangible or intangible, which is used by Target. All transactions between

occurred in the ordinary course of business on a basis no less favorable to
Target as would be obtained in a comparable arm's length transaction with a
person not an affiliate.

            -------

fact necessary in order to make the statements made, in light of the
circumstances under which they were made, not misleading.

              Individual Representations and Warranties of Seller

     Each of the persons who is a Seller, severally but not jointly, represents
and warrants (except in the case of Section 3.5 which representation and
warranty is being made exclusively by Kevin Brice) to Buyer as of the date of
this Agreement as to such person as follows:

     3.1.   Capital Stock.  No class of stock of Target is authorized or
            -------------
outstanding other than as described in Section 2.11. Seller is the owner,
beneficially and of record, of the Securities set forth opposite such person's
name on Schedule 3.1 hereto (the "Individual Shares"). The Individual Shares
will not be subject to any liens or restrictions on transfer, other than
restrictions imposed by applicable securities laws and, upon the transfer of the
Individual Shares to Buyer, Buyer will obtain good and marketable title to the
Individual Shares, free and clear of all liens, claims and encumbrances of any
kind. At the Closing Date, there will be no authorized or outstanding option,
subscription, warrant, call, right, commitment or other agreement obligating
Seller to issue or transfer any of his shares of capital stock or options of
Target or any securities convertible into or exercisable for any shares of such
capital stock. None of Target or Seller is a party to any voting trust, proxy or
other agreement or understanding with respect to the Individual Shares.

     3.2.   Authorization; Consents; Enforceability.
            ---------------------------------------

            (a)  This Agreement and the Transaction Documents to which such
Seller is a party or a signatory, have been duly authorized, executed and
delivered by such Seller and constitute the legal, valid and binding obligation
of such Seller enforceable in accordance with their respective terms subject to
applicable bankruptcy, insolvency and similar laws affecting creditors' rights
generally and to general principles of equity.

                                       19
<PAGE>

          (b)  No Consent is required to be obtained by any Seller, (or by any
of his respective Affiliates) from, and no notice or filing is required to be
given by, any Seller (or by any of his respective Affiliates) to or made by any
Seller (or by any of his respective Affiliates) with, any Governmental Authority
or other person in connection with the execution, delivery and performance by
such person of this Agreement.

          (c)  The execution and delivery by each Seller of this Agreement and
the Transaction Documents to which it is a party do not, and the consummation by
such person of the transactions contemplated hereby or thereby will not (i)
violate or conflict with, or result (with the giving of notice or lapse of time
or both) in a violation of or constitute a default (or give rise to any right of
termination, cancellation or acceleration) under any of the terms, conditions or
provisions of any note, agreement or other instrument or obligation to which any
Seller is a party or by which any of its assets may be bound, except for such
violations or defaults (or rights of termination, cancellation or acceleration)
as to which requisite waivers or consents have been obtained or (iii) violate
any order, writ, injunction, decree, statute, rule or regulation applicable to
any Seller or any of its respective assets.

     3.3. Litigation.  There is no litigation, action, claim, proceeding or
          ----------
governmental investigation pending or, to the knowledge of any Seller,
threatened against such Seller which may affect such Seller's ability to perform
his obligations under this Agreement.

     3.4. Investment.  Each Seller (a) understands that the Unregistered Buyer
          ----------
Common Stock to be received by such person has not been, as of the date hereof,
registered under the Securities Act of 1933, as amended (the "Securities Act"),
or under any state securities laws, and is being offered and sold in reliance
upon federal and state exemptions for transactions not involving any public
offering, (b) understands that the Unregistered Buyer Common Stock may not be
reoffered, resold, pledged or otherwise transferred except pursuant to an
effective registration statement or in accordance with another exemption from
the registration requirements of the Securities Act, (c) is acquiring the
Unregistered Buyer Common Stock solely for his own account as a principal, for
investment purposes and not with a view to the sale or distribution thereof
except pursuant to the Registration Rights Agreement, (d) has received certain
information concerning the Buyer and has had the opportunity to obtain
additional information as desired in order to evaluate the merits and the risks
inherent in holding the Unregistered Buyer Common Stock, (e) is able to bear the
economic risk and lack of liquidity inherent in holding the Unregistered Buyer
Common Stock, (f) is a sophisticated investor with knowledge and experience in
business and financial matters and (g) is an "accredited investor" (as such term
is defined under the Securities Act).

     3.5. Assets and Revenues.  Kevin Brice is the "ultimate parent entity" (as
          -------------------
such term is defined in 16 C.F.R. Section 801.1(a)(3)) of Target.  Kevin Brice,
together with any entity controlled by him, does not have assets having an
aggregate book value of $10 million or more (as determined in accordance with 16
C.F.R. Section 801.11(d)) or sales of $10 million or more in the most recent
fiscal year. The term "controlled" as used in the preceding sentence shall have
the meaning set forth in 16 C.F.R. 801(b). This representation and warranty is
made solely for the purpose of determining the applicability to the transactions
contemplated by this Agreement of the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended.

     without the prior consent of Buyer; and

               (iv)  Target shall not, without Buyer's prior written approval,

     Section 2.13 to be untrue.

          (d)  From the date hereof through the Closing Date, Target shall: (i)

satisfaction of the conditions set forth in subsection 5.1(a) hereof or the
obligations by Target set forth in Section 6 hereof.

     6.2. Post-Closing Covenants.
          ----------------------

          (a)  From and after the Closing, Seller shall execute all such
instruments or documents and take all such other actions as Buyer may reasonably
request to effectuate the transactions contemplated hereby, including, without
limitation obtaining of any necessary or advisable consents not required by
Buyer prior to Closing in connection with the transactions contemplated hereby
(including consents to assignment of contract rights and obligations as Buyer
may reasonably request).

          (b)  Subject to the other provisions of this Section 6.2, Mr. Brice
shall indemnify, defend and hold harmless Buyer, its officers, directors,
employees, partners, members, shareholders, Affiliates (and their officers,
directors, employees, members, partners and shareholders) and agents
(collectively, the "Buyer Indemnified Parties") from and against any action,
loss, liability, damage, claim, fine, penalty, lien or expense, including
reasonable legal costs, attorneys' fees and expenses (collectively, "Buyer
Loss"), to the extent the same arises out of (i) any breach by any
representation, warranty, agreement or covenant made by Mr. Brice herein or in
any Transaction Document; and (ii) any Tax liability of Target for periods up to
and including the Closing Date. In the case of Taxes that are imposed on a
periodic basis and that are payable for a period that includes the Closing Date,
the portion of such Tax which relates to the portion of such Taxable period
ending on the Closing Date shall (x) in the case of any Taxes other than Taxes
based upon or related to income or receipts, be deemed to be the amount of such
Tax for the entire Taxable period multiplied by a fraction the numerator of
which is the number of days in the Taxable period ending on the Closing Date and
the denominator of which is the number of days in the entire Taxable period, and
(y) in the case of any Tax based upon or related to income or receipts be deemed
equal to the amount which would be payable if the relevant Taxable period ended
on the Closing Date.

          (c)  Buyer shall indemnify, defend and hold harmless Mr. Brice from
and against any action, loss, liability, damage, claim, fine, penalty, lien,
interest or expense, including without limitation, reasonable legal costs,
attorneys' fees and expenses (collectively, "Brice Loss"), to the extent the
same arises out of (i) breach by Buyer of any representation, warranty,
agreement or covenant made by Buyer herein or in any Transaction Document and
(ii) any liability, obligation or covenant of Target arising after the Closing
Date.

          (d) (i)   If any third party shall notify Buyer or Mr. Brice (in such
case, "Indemnified Party") with respect to any matter (a "Third Party Claim")
which may give rise to a claim for indemnification against the other
("Indemnified Party") under Section 6.2(b), then Indemnified Party shall
promptly notify Indemnifying Party in writing; provided, however, that no delay
                                               --------  -------
on the part of Indemnified Party notifying Indemnifying Party shall relieve
Indemnifying Party from any obligation hereunder.


                    (ii)  Indemnifying Party will have the right to assume the
     defense of the Third Party Claim with counsel of his or its choice
     reasonably satisfactory to Indemnified Party at any time within twenty (20)
     days after Indemnified Party has given notice of the Third Party Claim;
     provided, however, that Indemnifying Party must conduct the defense of the
     --------  -------
     Third Party Claim actively and diligently thereafter in order to preserve
     its rights in this regard; and provided further that Indemnified Party may
                                    -------- -------
     retain separate co-counsel of its choice (and at its sole discretion) and
     the reasonable fees and expenses of such counsel shall be paid by
     Indemnifying Party.

                    (iii) So long as Indemnifying Party has assumed and is
     conducting the defense of the Third Party Claim in accordance with
     Paragraph (ii) above, Indemnifying Party will not consent to the entry of
     any judgment or enter into any settlement with respect to the Third Party
     Claim without the prior written consent of Indemnified Party.

                    (iv)  In the event that Indemnifying Party does not assume
     and conduct the defense of the Third Party Claim in accordance with
     Paragraph (ii) above, (A) Indemnified Party may defend against and consent
     to the entry of any judgment, or enter into any settlement with respect to,
     the Third Party Claim in any manner he or it reasonably may deem
     appropriate and (B) Indemnifying Party will remain responsible for any
     Buyer Loss or Brice Loss, as applicable, that Indemnified Party may suffer
     resulting from, arising out of, relating to, in the nature of, or caused
     by, the Third Party Claim to the fullest extent provided in Section 6.2(b)
     or (c), as applicable.

          (e)       No claim for indemnification under this Agreement may be
made by an Indemnified Party unless notice is given by such Indemnified Party to
the Indemnifying Party on or prior to the eighteen (18) month anniversary of the
Closing Date. Notwithstanding anything contained herein to the contrary, the
provisions for indemnity contained in Section 6.2(b) or (c) shall become
effective only in the event that the aggregate amount of all indemnifiable
claims for which Indemnifying Party is liable under Section 6 exceeds $140,000
(the "Indemnification Basket"), and, in the event the indemnifiable losses for
which Indemnifying Party is liable exceed the Indemnification Basket,
Indemnifying Party shall be responsible for the entire amount of all such losses
in excess of the Indemnification Basket up to but not exceeding the sum of (i)
Fifteen Million Dollars ($15,000,000) and (ii) the actual amount of Contingent
Consideration paid by Buyer to Mr. Brice (the "Indemnification Cap"). Any amount
required to be paid by Indemnifying Party with respect to any indemnification
claim under this Section 6 shall be reduced to the extent of any amounts that
have been paid to Indemnified Party pursuant to an insurance policy of
Indemnified Party with respect to such loss. Neither the Indemnification Cap nor
the Indemnification Basket shall apply in respect to a claim for indemnity which
is related to a claim under this Agreement which resulted from (i) knowing and
intentional fraud on the part of the Indemnifying Party or (ii) a violation of
Sections 2.6, 2.11, 3.1 and 4.7 herein. Buyer will

                                      29
<PAGE>

be able to reduce the amounts to be paid to Mr. Brice pursuant to Section
1.5(e), (f) and (g) herein by the amount of any Buyer Loss as to which there has
been a final determination.

               (f)  Mr. Brice hereby agrees that he will not make any claim for
indemnification against Target by reason of the fact that he was a director,
officer, employee or agent of Target or any of its Affiliates or was serving at
the request of any such entity as a partner, trustee, director, officer,
employee or agent of another entity (whether such claim is for judgments,
damages, penalties, fines, costs, amounts paid in settlement, losses, expenses
or otherwise and whether such claim is pursuant to any statute, charter
document, bylaw, agreement or otherwise) with respect to any action, suit,
proceeding, complaint, claim, or demand brought by Buyer against Mr. Brice for
any breach by Mr. Brice of any representation, warranty, agreement or covenant
made by Mr. Brice herein or in any Transaction Document.

               (g)  Each Seller hereby agrees that it will sell shares of Buyer
Common Stock only in compliance with applicable federal and state securities
laws.

               (h)  Buyer hereby agrees that during the first three (3) years
following the Closing Date, the employees of Target shall, with the exception of
standard business travel, perform their duties in the greater Atlanta, Georgia
area.

               (i)  Buyer will grant, in the aggregate and in the ordinary
course of business, at such time as Buyer typically grants options to other of
its employees but in no event later than March 31, 2000, options to purchase
20,000 shares of Buyer Common Stock to the employees of Target specified in the
certificate delivered pursuant to Section 5.3(h) herein; provided, however, that
                                                         --------  -------
Buyer, after engaging in meaningful consultation with Kevin Brice, will be able
to apportion such options among such employees as Buyer sees fit.

               (j)  From and after the Closing Date until the Three (3) Year
Anniversary Date, Buyer shall continuously maintain, at its sole expense for the
benefit of Seller, in effect a registration statement filed under the Securities
Act and pursuant to Rule 415 promulgated pursuant thereto with respect to the
resale by Seller of all unregistered Buyer Common Stock contemplated to be
issued by Buyer pursuant to Section 1.5 hereto.

               (k)  Buyer will use commercially reasonable efforts to obtain
confidential treatment of Exhibit A and Schedule 1.5(a) with the Securities and
Exchange Commission.

               (l)  Kevin Brice shall use his best efforts to expand the
Integrated Assessment Product identified in Section 1.5(e) into additional
subject areas.

               (m)  Seller shall not sell Buyer Common Stock other than through
Volpe Brown Whelan & Company or another market maker of Buyer Common Stock.

     legal proceeding or threat thereof;

                    (vi)   at any time on or prior to the Closing Date, by
     mutual written consent of the Target, Seller and the Buyer; or

                    (vii)  by any party after the Termination Date, unless the

               (b)  If any party terminates this Agreement pursuant to Section
7.13(a) above, all rights and obligations of the parties hereunder shall

Citibank, N.A. in effect on the Termination Date. Notwithstanding the foregoing,
nothing in this Section shall prevent the non-failing party from exercising any
other remedies it may have available to it and the Break-up Fee shall not be

                    (i)  Target and Seller shall cooperate fully, as and to the
     extent reasonably requested by Buyer, in connection with the filing of Tax
     returns pursuant to this section and any audit, litigation or other
     proceeding with respect to Taxes. Such cooperation shall include the
     retention and (upon Buyer's request) the provision of records and
     information which are reasonably relevant to any such audit, litigation or
     other proceeding and making employees available on a mutually convenient
     basis to provide additional information and explanation of any material
     provided hereunder. Target and Seller agree (A) to retain all books and
     records with respect to Tax matters pertinent to Target relating to any
     taxable period beginning before the Closing Date until the expiration of
     the statute of limitations (and any extensions thereof) of the respective
     taxable periods, and to abide by all record retention agreements entered
     into with any taxing Authority and (B) to give Buyer reasonable written
     notice prior to transferring, destroying or discarding any such books and
     records and, if Buyer or the other party so requests, Target or Seller, as
     the case may be, shall allow Buyer or the other party to take possession of
     such books and records.

          Seller further agrees, upon request, to use its best efforts to obtain
any certificate or other document from any Authority or any other Person as may
be necessary to mitigate, reduce or eliminate any Tax that could be imposed
(including, but not limited to, with respect to the transactions contemplated
hereby).

          Seller further agrees, upon request, to provide Buyer with all
information that Buyer may be required to report pursuant to Section 6043 of the
Code and all Treasury Department Regulations promulgated thereunder.

          (d)  Tax Sharing Agreements. All tax sharing agreements or similar
               ----------------------
agreements, if any, with respect to or involving Target shall be terminated as
of the Closing Date.

     (k) "Shelf Registration Statement" means a shelf registration statement of
this Company pursuant to the provisions of Section 2 hereof filed by the Company

applicable, and, at the option of the Company, such shares of capital stock (or
other securities of the Company) as the Company shall designate therein (the
"Company Shelf Securities") on an appropriate form under Rule 415 under the
Securities Act, or any similar rule that may be adopted by the Commission,
amendment and supplements to such registration statement, including post-
effective amendments, in each case including the prospectus contained therein,
all exhibits thereto and all material incorporated by reference therein.

     As used herein, all capitalized terms not otherwise defined herein shall
have the meanings set forth in the Purchase Agreement.

Section 2.  Shelf Registration.
            ------------------

     (a) If, pursuant to Section 1.5 of the Purchase Agreement, the Company
elects to issue to the Holders shares of unregistered Buyer Common Stock on
either the Three-Month Anniversary Date, the Six-Month Anniversary Date, the
One-Year Anniversary Date, the Two-Year Anniversary Date or the Three-Year
Anniversary Date, then the Company shall file within 5 business days of the
applicable Anniversary Date a Shelf Registration Statement relating to (i) the
offer and sale of that number of shares of unregistered Buyer Common Stock
issued by the Company to the Holders on such Anniversary Date pursuant to
Section 1.5(c), (d), (e), (f) or (g) of the Purchase Agreement and (ii) such
number of shares of capital stock of the Company (or other securities of the
Company) as the Company shall designate in such Shelf Registration Statement.
Thereafter, the Company shall use commercially reasonable efforts to cause such

                                       2
<PAGE>

Shelf Registration Statement to be declared effective under the Act as promptly
as practicable; provided, however, that no Holder shall be entitled to have the
Registrable Securities held by him covered by such Shelf Registration unless
such Holder is in compliance with the terms of this Agreement.

     (b) The Company shall use commercially reasonable efforts (i) to keep the
Shelf Registration Statement continuously effective in order to permit the
prospectus forming part thereof to be useable by the Holders until two (2) years
from its effective date or such shorter period that will terminate when all the
Registrable Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement, and (ii) after the
effectiveness of the Shelf Registration Statement and promptly upon the request
of any Holder, to take any action reasonably necessary to register the sale of
any Registrable Securities of such Holder and to identify such Holder as a
selling securityholder under such Shelf Registration Statement.

     (c) In connection with any Shelf Registration Statement, the Company shall:

          (i)   prepare and file with the Commission a Shelf Registration
Statement, on an appropriate form pursuant to Rule 415 of the Securities Act and
which the Company is eligible to use, with respect to such shares and use its
commercially reasonable best efforts to cause such Shelf Registration statement
to become and remain effective as provided herein;

          (ii)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
current and to comply with all of the provisions of the Act with respect to the
disposition of all shares covered by such registration statement, including such
amendments and supplements as may be necessary to reflect the intended method of
disposition from time to time of the prospective seller of such Registrable
Securities; and

          (iii) use its commercially reasonable best efforts to register or
qualify the Registrable Securities covered by such registration statement under
such other securities or blue sky or other applicable laws of such jurisdiction
within the United States as each prospective seller shall reasonably request, to
enable such seller to consummate the public sale or other disposition in such
jurisdictions of the Registrable Securities owned by such seller; provided,
however, that in no event shall the Company be obligated to qualify to do
business in any jurisdiction where it is not at the time so qualified or to take
any action that would subject it to service of process in suits other than those
arising out of the offer or sale of the Registrable Securities covered by such
registration statement in any jurisdiction where it is not at the time so
subject.

     (d) (i) Notwithstanding the other provisions of this Section 2, if at any
time the Company desires to effect a registered offering of securities (pursuant
to the Shelf Registration Statement or otherwise) and simultaneously therewith
any Holder desires to effect an underwritten offering pursuant to a Shelf
Registration Statement and if the underwriter determines that (i) marketing
factors require a limitation of the total number of shares to be underwritten,
or (ii) the offering

                                       3
<PAGE>

price per share would be reduced by the inclusion of the securities of the
Company, then the number of shares to be included in the underwriting shall be
allocated first, among the Holders who indicated to the Company their decision
to distribute any of their Registrable Securities through such underwriters in
proportion, as nearly as practicable, to the respective numbers of shares of
Registrable Securities which such Holders indicated initially they wished to be
included in the underwriting, then the remainder, if any, to the Company.

          (ii)  Anything in this Agreement to the contrary notwithstanding, the
Holders shall not offer any Registrable Securities pursuant to the Shelf
Registration Statement if such offering would require the Company (i) to furnish
any financial statements other than as of the end of a fiscal quarter or (ii) to
furnish any audited financial statements other than as of the end of a fiscal
year. In addition to the foregoing, in the event of a proposed offering by a
Holder pursuant to the Shelf Registration Statement, at such time as any
registration statement would be required to include audited financial statement
as of a fiscal year-end, the Company may delay the dissemination of the required
notice and the taking of any action to effect a supplement to the Shelf
Registration Statement until such time as such audited financial statements are
available in the ordinary course of business.

          (iii) Subject to Section 3 hereof, no Holder shall offer any
Registrable Securities pursuant to the Shelf Registration Statement within 30
days after the effectiveness of any other registration of the Company's
securities (other than a registration statement (A) on Form S-8 or any successor
form to such Form or in connection with any employee or director welfare,
benefit or compensation plan, (B) on Form S-4 or any successor form to such Form
or in connection with an exchange offer or merger transaction, (C) in connection
with a rights offering exclusively to existing holders of shares of Buyer Common
Stock, (D) in connection solely with an offering to employees of the Company or
its subsidiaries or (E) relating to a transaction pursuant to Rule 145 of the
Securities Act).

Section 3.  "Piggy-Back" Registrations.  (a) If at any time the Company proposes
             -------------------------
to register any of its securities under the Securities Act and, in connection
with such offering, any shareholders of the Company are given the opportunity to
sell their securities (other than (i) a registration statement on Form S-8 or
Form S-4, or their successors, or any other form for a similar limited purpose,
(ii) a registration statement used in connection with (x) an offering to
employees of the Company or its subsidiaries or (y) a rights offering
exclusively to existing holders of shares of Buyer Common Stock or (iii) a
registration statement covering only securities proposed to be issued in
exchange for securities or assets of another corporation), whether or not for
its own account, the Company shall furnish prompt written notice to all Holders
of its intention to effect such registration and the intended method of
distribution in connection therewith.  Upon the written request of a Holder made
to the Company within 10 days after the delivery of such notice by the Company,
the Company shall include in such registration the requested number of the
requesting Holder's Registrable Securities (a "Piggy-Back Registration");
provided, however, that such requested number shall be subject to the Company's
or the underwriter's right, in view of market conditions, to refuse or reduce
the number of shares that the Holders propose to be registered.

                                       4
<PAGE>

     (b) Nothing in Section 3 hereof shall create any liability on the part of
the Company, or any other person, to the Holders if the Company or any other
person should, for any reason, decide not to file a registration statement
proposed to be filed pursuant to Section 3(a) or to withdraw such registration
statement subsequent to its filing, regardless of any action whatsoever that a
Holder may have taken, whether as a result of the issuance by the Company of any
notice under Section 3(a) or otherwise.

Section 4.  Expenses of Registration.  In addition to the fees and expenses
            ------------------------
contemplated by Section 4 hereof, all expenses incurred in connection with one
registration per any Anniversary Date in respect of which unregistered
securities are issued pursuant to Section 2 hereof and all expenses incurred in
connection with Piggy-Back Registrations, including without limitation all
registration, filing and qualification fees, printing expenses, fees and
disbursements of counsel for the Company and expenses of any special audits of
the Company's financial statements incidental to or required by such
registration, shall be borne solely by the Company, except that the Company
shall not be required to pay underwriters' fees, discounts or commissions
relating to Registrable Securities sold for the account of any Holder or fees of
legal counsel for the Holders.

Section 5.  Registration Procedures.  In the case of each registration effected
            -----------------------
by the Company pursuant to this Agreement, the Company will keep each Holder
participating therein advised, promptly as soon as practicable, in writing as to
the initiation of each registration and as to the completion thereof.  At its
expense the Company will:

     (a) promptly prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to comply with the provisions of the Securities
Act;

     (b) furnish such number of prospectuses and other documents incident
thereto as a Holder from time to time may reasonably request in order to
facilitate the disposition of Registrable Securities owned by such Holder;

     (c) use commercially reasonable best efforts to obtain the withdrawal of
any order suspending the effectiveness of a registration statement, or the
lifting of any suspension of the qualification of any of the Registrable
Securities for sale in any jurisdiction, at the earliest possible moment;

     (d) subject to Section 2(c)(iii), register or qualify such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions as any Holder or underwriter reasonably requires;

     (e) cause all Registrable Securities covered by such registrations to be
listed on each securities exchange, including NASDAQ, on which similar
securities issued by the Company are then listed;

                                       5
<PAGE>

     (f) in the event of any underwritten public offering, enter into and
perform obligations under an underwriting agreement, in form and substance
reasonably satisfactory to the company, with the managing underwriter of such
offering;

     (g) cause its accountants to issue to the underwriter, if any, or the
Holders, if there is no underwriter, comfort letters and updates thereof, in
customary form and covering matters of the type customarily covered in such
letters with respect to underwritten offerings;

     (h) cause its counsel to issue to the underwriter, if any, or to the
Holders, if there is no underwriter, opinions in customary form and covering
matters of the type customarily covered in such opinions with respect to
underwritten offerings;

     (i) enter into such customary agreements (including underwriting agreements
in customary form);

     (j) make available for inspection by any seller of Registrable Securities,
any underwriter participating in any disposition pursuant to such registration
statement, and any attorney, accountant or other agent retained by any such
seller or underwriter, all financial and other records, pertinent corporate
documents and properties of the Company, and cause the Company's officers,
directors, employees and independent accountants to supply all information
reasonably requested by any such seller, underwriter, attorney, accountant or
agent in connection with such registration statement;

     (k) immediately notify each Holder, at any time a prospectus covered by
such registration statement is required to be delivered under the Securities
Act, of the happening of any event of which it has knowledge as a result of
which the prospectus included in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in the light of the circumstances then existing; and

     (l) take such other actions as shall be reasonably requested by any Holder.

Section 6.  Indemnification.
            ---------------

     (a) In the event of a registration, qualification or compliance of any of
the Registrable Securities under the Securities Act pursuant to Section 2 or
Section 3, the Company will indemnify and hold harmless each Holder of such
Registrable Securities thereunder, each underwriter of such Registrable
Securities thereunder and each other person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which such Holder,
underwriter or controlling person may become subject under the Securities Act,
insofar as such losses, claims, expenses, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Registrable Securities were registered under the Securities
Act, any preliminary prospectus or final prospectus contained therein, or any
amendment or supplement thereof, any offering circular or other offering
document or arise out of or are based upon the omission or alleged

                                       6
<PAGE>

omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of any rule or regulation promulgated under the Securities Act or any
state securities law or rule or regulation promulgated under the Securities Act
or any state securities law applicable to the Company and relating to action or
inaction required of the Company in connection with any such registration,
qualification or compliance, and will reimburse each such Holder, each of its
officers, directors and partners, and each person controlling such Holder, each
such underwriter and each person who controls any such underwriter, for any
reasonable legal and any other expenses incurred in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action; provided, that, notwithstanding the foregoing, the Company will not be
        --------
liable in any such case to the extent that any such loss, claim, expense, damage
or liability arises out of or is based upon any untrue statement or alleged
untrue statement or omission or alleged omission made by such Holder or
underwriter specifically for use therein.

     (b) Each Holder will, if Registrable Securities held by or issuable to such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify and hold harmless the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company and each underwriter within the meaning of the Securities
Act, and each other Holder, each of such other Holder's officers, directors and
partners and each person controlling such other Holder, against all losses,
claims, expenses, damages and liabilities (or actions in respect thereof)
arising out of or based upon any untrue statement or alleged untrue statement of
any material fact contained in any registration statement under which such
Registrable Securities were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof, any offering circular or other offering document, or arising out of or
based upon any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company, such Holders, such directors,
officers, partners, persons or underwriters for any reasonable legal or any
other expenses incurred in connection with investigating, defending or settling
any such claim, loss, damage, liability or action, in each case to the extent,
but only to the extent, that such untrue statement or alleged untrue statement
or omission or alleged omission is made in such registration statement,
preliminary prospectus, final prospectus, any amendment or supplement thereof,
any offering circular or other offering document in reliance upon and in
conformity with information furnished to the Company by such Holder specifically
for use therein; provided, however, the total amount for which any Holder, its
officers, directors and partners, and any person controlling such Holder, shall
be liable under this Section 5(b) shall be limited to the proportion of any such
loss, claim, damage, liability or expense which is equal to the proportion that
the public offering price of shares sold by such Holder under such registration
statement bears to the total public offering price of all securities sold
thereunder but not to exceed, in any event, the aggregate proceeds received by
such Holder from the sale of Registrable Securities sold by such Holder in such
registration, qualification or compliance.

     (c) Each party entitled to indemnification under this Section 5 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party")

                                       7
<PAGE>

promptly after such Indemnified Party has actual knowledge of any claims as to
which indemnity may be sought, and shall permit the Indemnifying Party to assume
the defense of any such claim or any litigation resulting therefrom, provided
                                                                     --------
that counsel for the Indemnifying Party, who shall conduct the defense of such
claim or litigation, shall be approved by the Indemnified Party (whose approval
shall not be unreasonably withheld), and the Indemnified Party may participate
in such defense at such party's expense, and provided further that the failure
of any Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations hereunder, unless such failure resulted in
actual detriment to the Indemnifying Party. The Indemnifying Party shall not be
liable to indemnify any Indemnified Party for any settlement of any such action
effected without the Indemnifying Party's consent. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect of such claim or litigation.

     (d) Notwithstanding the foregoing, to the extent that the provisions on
indemnification contained in the underwriting agreements entered into among the
selling Holders, the Company and the underwriters in connection with the
underwritten public offering are in conflict with the foregoing provisions, the
provisions in the underwriting agreement shall be controlling as to the
Registrable Securities included in the public offering.

     (e) If the indemnification provided for in this Section 5 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
thereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other hand in
connection with the statements or omissions which resulted in such loss,
liability, claim, damage or expense as well as any other relevant equitable
considerations. The relevant fault of the Indemnifying Party and the Indemnified
Party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the Indemnifying Party or by
the Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Notwithstanding the foregoing, the amount any Holder shall be obligated to
contribute pursuant to this Section 5(e) shall be limited to an amount equal to
the proceeds to such Holder of the Registrable Securities sold pursuant to the
registration statement which gives rise to such obligation to contribute.

     (f) The indemnification provided by this Section 5 shall be a continuing
right to indemnification and shall survive the registration and sale of any
securities by any definition entitled to indemnification hereunder and the
expiration or termination of this Agreement.

Section 7.  Lockup Agreement.  In consideration for the Company agreeing to its
            ----------------
obligations under this Agreement, each Holder agrees in connection with any
underwritten registration of the

                                       8
<PAGE>

Company's securities upon the request of the Company and the underwriters
managing the underwritten offering of the Company's securities, not to publicly
sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Registrable Securities (other than those included in
the registration) without the prior written consent of the Company and such
underwriters for such period of time from the effective date of such
registration as the Company and the underwriters may specify (the "Lock Up");
provided, however, that all officers and directors of the Company enter into
- --------  -------
similar agreements.

Section 8.  Obligations of the Holders.  (a) It shall be a condition precedent
            --------------------------
to the obligation of the Company to include any Registrable Securities of any
Holder in a registration statement pursuant to Section 2 or Section 3 of this
Agreement that the Holder shall promptly furnish to the Company such information
regarding such Holder or Holders and the intended method of distribution
proposed by such Holder or Holders as the Company may request in writing and as
shall be reasonably required in connection with any registration referred to
herein.  Any such information, or any comments on any such information included
in a draft of a registration statement provided to a Holder for its comment,
shall be provided to the Company within any reasonable time period requested by
the Company.

     (b) Each Holder shall notify the Company, at any time when a prospectus is
required to be delivered under applicable law, of the happening of any event as
a result of which the prospectus included in the applicable registration
statement, as then in effect, in each case only with respect to information
provided by such Holder, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing. Such Holder shall immediately upon the happening of any such event
cease using such prospectus. Any other Holders shall cease using such prospectus
immediately upon receipt of notice from the Company to that effect. Each Holder
promptly shall return to the Company any copies of any prospectus in its
possession (other than permanent file copies) that contains an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing.

Section 9.  Sales.  With a view to making available to Holders of Registrable
            -----
Securities the benefits of certain rules and regulations of the Commission which
may permit the sale of the Registrable Securities by the Holders to the public
without registration, the Company agrees at all times prior to the termination
of this Agreement:

          (i)   make and keep public information available, as those terms are
understood and defined in Rule 144 and Rule 144A;

          (ii)  use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

          (iii) furnish to each Holder so long as such Holder owns any
Registrable Securities forthwith, upon written request, a written statement by

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual

           (a) The sale, transfer, conveyance, assignment and delivery by Seller

referred to hereinafter as the "Securities."

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