Item 2. Acquisition or Disposition of Assets.

     Effective August 19, 1998 (the "LECG Effective Date"), The Metzler Group,
Inc. (the "Company") completed the acquisition of all of the outstanding
securities of LECG, Inc. ("LECG"), an economic services consulting firm
organized under the laws of California. Pursuant to a Merger Agreement dated
July 1, 1998 (attached hereto as Exhibit 2.1), a wholly owned subsidiary of the
Company, MGI Acquisition Corp., merged with and into LECG on the LECG Effective
Date. Consequently, LECG is now a wholly owned subsidiary of the Company. LECG
stockholders received Company common stock valued at approximately $238 million,
calculated by using the final closing bid for the Company's common stock on the
LECG Effective Date, in exchange for substantially all outstanding LECG shares.
The Company exchanged 7.6 million shares of its common stock for substantially
all of the outstanding common stock of LECG. The transaction will be accounted
for by the pooling of interests method of accounting and will qualify as a tax-
free reorganization. Following the combination with LECG, the Company had 30.3
million issued and outstanding shares.

     Effective August 31, 1998 (the "PCLLC Effective Date"), the Company
completed the acquisition of all of the outstanding securities of Peterson
Consulting L.L.C. ("PCLLC"), an Illinois Limited Liability Company doing
business as Peterson Worldwide LLC. Pursuant to a Merger Agreement dated August
20, 1998 (attached hereto as Exhibit 2.2), a wholly owned subsidiary of the
Company, MGI Acquisition II L.L.C., merged with and into PCLLC on the PCLLC
Effective Date. Consequently, PCLLC is now a wholly owned subsidiary of the
Company. PCLLC stockholders received Company common stock valued at
approximately $157 million calculated by using the final closing bid for the
Company's common stock on the PCLLC Effective Date, in exchange for
substantially all outstanding PCLLC shares. The Company exchanged 5.6 million
shares of its common stock for substantially all of the outstanding common stock
of PCLLC. The transaction will be accounted for by the pooling of interests
method of accounting and will qualify as a tax-free reorganization. As a result
of the combination with PCLLC, the Company will have 35.9 million issued and
outstanding shares.

Item 7 (a) Financial Statements of Business Acquired

LECG, Inc. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. Basis of Presentation

  The accompanying Consolidated Financial Statements have been prepared
pursuant to the rules and regulations of the Securities and Exchange
Commission ("SEC") and, in management's opinion, include all adjustments
necessary for a fair statement of results for such interim periods. Certain
information and note disclosures normally included in annual financial
statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to SEC rules or
regulations; however, the Company believes that the disclosures made are
adequate to make the information presented not misleading.

  The interim results for the six-month periods ended June 30, 1998
and 1997 are not necessarily indicative of results for the full year. It is
suggested that these consolidated financial statements be read in conjunction
with the consolidated financial statements and notes thereto included in the
Company's Registration Statement on Form S-4 dated July 24, 1998.
<PAGE>
2. Pro Forma Adjustments to Consolidated Financial Statements

  The pro forma consolidated statements of income have been adjusted to
reflect a provision for income taxes assuming an effective tax rate of 41
percent that would have been recorded had the Company been a C Corporation.

Item 7 (b) Pro Forma Financial Information

  The Company completed its acquisition of LECG on August 19, 1998 by exchanging
7.6 million shares of the Company's common stock for substantially all of the
outstanding common stock of LEGG. The accompanying unaudited pro forma condensed
combined balance sheet combines the Company's historical consolidated balance
sheet and the balance sheet of LECG as if the transaction had been consummated
on June 30, 1998, and the unaudited pro forma condensed combined statement of
operations for the six month periods ended June 30, 1999 and 1997 reflects the
merger with LECG, applying the pooling-of-interests method of accounting. The
unaudited pro forma condensed combining financial statements give effect to the
issuance of the Company's common stock in exchange for substantially all the
outstanding shares of common stock of LECG.

  The unaudited pro forma condensed combining financial statements are presented
for illustrative purposes only and do not purport to represent what the
Company's results of operations or financial position would have been had the
merger with LECG occurred on the dates indicated or for any future period or
date, and are therefore qualified in their entirety by reference to and should
be read in conjunction with the historical financial statements of the Company
and LECG.

Item 7 (b) Notes to Unaudited Pro Forma Condensed Combining Financial Statements


Note A - Description of Business Combination

The accompanying unaudited condensed combining financial statements reflect all 
adjustments which, in the opinion of management, are necessary for fair 
presentation. All adjustments are of a normal recurring nature. All intercompany
accounts and transactions have been eliminated. On July 31, 1997, the Company 
issued 7.6 million shares of common stock for substantially all the outstanding 
common stock of LECG. Because this acquisition is being treated as a pooling of 
interests for accounting purposes, the Company's consolidated financial 
statements as of June 30, 1998 and for the six months ended June 30, 1998 and 
1997 are being restated to include LECG's assets, liabilities and operating 
results.

Note B - Pro Forma Income per Share

The calculation of basic and diluted net income per share for the pro forma 
financial statements uses the applicable weighted average number of outstanding 
shares of LECG adjusted to equivalent shares of the Company's common stock.

                                  The Merger
 
  1.1. Effective Time of The Merger. Subject to the provisions of this
Agreement, an abbreviated version of this Agreement meeting the requirements
of Section 1101 of the California General Corporation Law ("CGCL"), certified
by the president or any vice president and the secretary or assistant
secretary of each of Sub and LECG in accordance with Section 1103 of the CGCL,

time thereafter as is provided in the Certificate of Merger (the "EFFECTIVE
TIME").
 
  1.2. Closing. The closing of the Merger (the "CLOSING") will take place at

  1.3. Effects of the Merger.
 
    (a) At the Effective Time, (i) the separate existence of Sub shall cease

  referred to herein as the "CONSTITUENT CORPORATIONS" and LECG is sometimes
  referred to herein as the "SURVIVING CORPORATION"), (ii) the Articles of
  Incorporation of LECG as in effect immediately prior to the Effective Time

                                      A-4
<PAGE>
 
    (b) At and after the Effective Time, the effects of the Merger shall be
  as provided in the applicable provisions of the CGCL and the DGCL. Without
  limiting the generality of the foregoing, and subject thereto, the
  Surviving Corporation shall possess all the rights, privileges, powers and
  franchises of a public as well as of a private nature, and be subject to
  all the restrictions, disabilities and duties of each of the Constituent
  Corporations; and all and singular rights, privileges, powers and
  franchises of each of the Constituent Corporations, and all property, real,
  personal and mixed, and all debts due to either of the Constituent
  Corporations on whatever account, as well as for stock subscriptions and
  all other things in action or belonging to each of the Constituent
  Corporations, shall be vested in the Surviving Corporation, and all
  property, rights, privileges, powers and franchises, and all and every
  other interest shall be thereafter as effectually the property of the
  Surviving Corporation as they were of the Constituent Corporations, and the
  title to any real estate vested by deed or otherwise, in either of the
  Constituent Corporations, shall not revert or be in any way impaired; but
  all rights of creditors and all liens upon any property of either of the
  Constituent Corporations shall be preserved unimpaired, and all debts,
  liabilities and duties of the Constituent Corporations shall thereafter
  attach to the Surviving Corporation, and may be enforced against it to the
  same extent as if such debts and liabilities had been incurred by it.
 
  1.4. Directors and Officers. The directors of Sub immediately prior to the
Effective Time shall be the initial directors of the Surviving Corporation,
each to hold office in accordance with the Articles of Incorporation and
Bylaws of the Surviving Corporation, and the officers of the Surviving
Corporation shall initially be the persons set forth on Schedule 1.4 hereto,
and all other officers of the Surviving Corporation as of the Effective Time,
in each case until their respective successors are duly elected or appointed.
 
                                  ARTICLE 2.
 
                           Conversion of Securities
 
  2.1. Conversion of Capital Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holders of any shares of LECG
Common Stock (as defined in Section 3.2) or capital stock of Sub:
 
    (a) Capital Stock of Sub. Each issued and outstanding share of the
  capital stock of Sub shall be converted into and become one fully paid and
  nonassessable share of common stock, $.01 per share, of the Surviving
  Corporation.
 
    (b) Cancellation of Treasury Stock and Metzler-Owned Stock. Any shares of
  LECG Common Stock that are owned by Metzler, Sub or any other wholly-owned
  Subsidiary of Metzler shall be canceled and retired and shall cease to
  exist and no stock of Metzler or other consideration shall be delivered in
  exchange therefor.
 
    (c) Conversion of LECG Common Stock. Subject to Section 2.3, each issued
  and outstanding share of LECG Common Stock (other than shares to be
  canceled in accordance with Section 2.1(b)) shall be converted into the
  right to receive 0.6 fully paid and nonassessable shares of Metzler Common
  Stock (as defined in Section 4.2) (adjusted for any stock split or stock
  dividend effected between the date of this Agreement and the Effective
  Time). All shares of LECG Common Stock, when converted, shall no longer be
  outstanding and shall automatically be canceled and retired and shall cease
  to exist, and each holder of a certificate representing any such shares
  shall cease to have any rights with respect thereto, except the right to
  receive the shares of Metzler Common Stock and any cash in lieu of
  fractional shares of Metzler Common Stock to be issued or paid in
  consideration therefor upon the surrender of such certificate in accordance
  with Section 2.2, without interest.
 
    (d) LECG Stock Plans and Options. At the Effective Time, Metzler shall
  assume LECG's rights and obligations under each of the outstanding options
  previously granted under the stock option plan of LECG, as amended and
  dated as of October, 1997 (the "LECG STOCK OPTION PLAN") (each such option
  existing immediately prior to the Effective Time being called an "EXISTING
  OPTION," and each such option so
 
                                      A-5
<PAGE>
 
  assumed by Metzler being called an "ASSUMED OPTION"), by which assumption
  the optionee shall have the right to purchase that number of shares of
  Metzler Common Stock (with any fractional share to be rounded down to the
  nearest whole share) into which the number of shares of LECG Stock subject
  to purchase under the Existing Option would be converted pursuant to the
  terms of the Merger as described in Section 2.1(c) hereof. Each Assumed
  Option shall constitute a continuation of the Existing Option, substituting
  Metzler for LECG as issuer. The aggregate exercise price for the total
  number of shares of Metzler Common Stock subject to the Assumed Option
  shall be the aggregate exercise price at which the Existing Option was
  exercisable for the total number of shares of LECG Common Stock, and the
  purchase price per share of Metzler Common Stock thereunder shall be such
  aggregate exercise price divided by the total number of whole shares of
  Metzler Common Stock covered thereby (with any fraction of a cent to be
  rounded up to the nearest whole cent); provided, however, that in the case
  of any Existing Option to which Section 422 of the Code applies, the option
  price, the number of shares purchasable pursuant to such option and the
  terms and conditions of exercise of such option shall be determined in
  order to comply with Section 424(a) of the Code. The assumption of the
  Assumed Options by Metzler as provided in this Section 2.1(d) shall not,
  except as provided herein, provide the holders thereof additional benefits
  which they did not have immediately prior to the Effective Time or relieve
  the holders thereof of any obligations or restrictions applicable to the
  Assumed Options or the shares of Metzler Common Stock obtainable upon
  exercise of the Assumed Options. Metzler shall take all corporate action
  necessary to reserve and make available for issuance a sufficient number of
  shares of Metzler Common Stock for delivery under the Assumed Options.
 
  LECG shall take such action as is necessary to cause the ending date of the
then current offering period under the LECG Stock Purchase Plan (the "LECG
STOCK PURCHASE PLAN") to be the last trading day on which the LECG Common
Stock is traded on The New York Stock Exchange immediately prior to the
Effective Time (the "FINAL LECG PURCHASE DATE"); provided, that, such change
in the offering period shall be conditioned upon the consummation of the
Merger. On the Final LECG Purchase Date, LECG shall apply the funds credited
as of such date under the LECG Stock Purchase Plan within each participant's
payroll withholding account to the purchase of whole shares of LECG Common
Stock in accordance with the terms of the LECG Stock Purchase Plan.
 
  Employees of LECG as of the Effective Time shall be permitted to participate
in the Metzler Stock Purchase Plan commencing on the first enrollment date of
such plan following the Effective Time, subject to the eligibility provisions
of such plan (with employees receiving credit, for purposes of such
eligibility provisions, for service with LECG or Sub).
 
  2.2. Exchange of Certificates. The procedures for exchanging outstanding
shares of LECG Common Stock for Metzler Common Stock pursuant to the Merger
shall be as follows:
 
    (a) Exchange Agent. As of the Effective Time, Metzler shall deposit with
  American Stock Transfer and Trust Company (the "EXCHANGE AGENT"), for the
  benefit of the holders of shares of LECG Common Stock, certificates
  representing the shares of Metzler Common Stock issuable pursuant to
  Section 2.1 in exchange for outstanding shares of LECG Common Stock (such
  shares of Metzler Common Stock, together with any dividends or
  distributions with respect thereto, being hereinafter referred to as the
  "EXCHANGE FUND").
 
    (b) Exchange Procedures. As soon as reasonably practicable after the
  Effective Time, the Exchange Agent shall mail to each holder of record of a
  certificate or certificates which immediately prior to the Effective Time
  represented outstanding shares of LECG Common Stock (each a "CERTIFICATE"
  and, collectively, the "CERTIFICATES") and which shares were converted
  pursuant to Section 2.1 into the right to receive shares of Metzler Common
  Stock (i) a letter of transmittal (which shall specify that delivery shall
  be effected, and risk of loss and title to the Certificates shall pass,
  only upon delivery of the Certificates to the Exchange Agent and shall be
  in such form and have such other provisions as Metzler and LECG may
  reasonably specify), (ii) instructions for use in effecting the surrender
  of the Certificates in exchange for certificates representing shares of
  Metzler Common Stock and (iii) the notice of approval of the Merger and
 
                                      A-6
<PAGE>
 
  accompanying statutory materials, information and instruction as required
  by Section 1301(a) of the CGCL). Upon surrender of a Certificate for
  cancellation to the Exchange Agent or to such other agent or agents as may
  be appointed by Metzler, together with such letter of transmittal, duly
  executed, the holder of such Certificate shall be entitled to receive in
  exchange therefor a certificate representing that number of whole shares of
  Metzler Common Stock which such holder has the right to receive pursuant to
  the provisions of this Section 2.2(b), and the Certificate so surrendered
  shall immediately be canceled. In the event of a transfer of ownership of
  LECG Common Stock which is not registered in the transfer records of LECG,
  a certificate representing the proper number of shares of Metzler Common
  Stock may be issued to a transferee if the Certificate representing such
  LECG Common Stock is presented to the Exchange Agent, accompanied by all
  documents required to evidence and effect such transfer and by evidence
  that any applicable stock transfer taxes have been paid. Until surrendered
  as contemplated by this Section 2.2, each Certificate shall be deemed at
  any time after the Effective Time to represent only the right to receive
  upon such surrender the certificate representing shares of Metzler Common
  Stock and cash in lieu of any fractional shares of Metzler Common Stock as
  contemplated by this Section 2.2. The instructions for effecting the
  surrender of the Certificates shall set forth procedures that must be taken
  by the holder of any Certificate that has been lost, destroyed or stolen.
  It shall be a condition to the right of such holder to receive a
  certificate representing shares of Metzler Common Stock that the Exchange
  Agent shall have received, along with the letter of transmittal, a duly
  executed lost certificate affidavit, including an agreement to indemnify
  Metzler, signed exactly as the name or names of the registered holder or
  holders appeared on the books of LECG immediately prior to the Effective
  Time, together with a customary bond and such other documents as Metzler or
  the Exchange Agent may reasonably require in connection therewith.
 
    (c) Distributions with Respect to Unexchanged Shares. No dividends or
  other distributions declared or made after the Effective Time with respect
  to Metzler Common Stock with a record date after the Effective Time shall
  be paid to the holder of any unsurrendered Certificate with respect to the
  shares of Metzler Common Stock represented thereby and no cash payment in
  lieu of fractional shares shall be paid to any such holder pursuant to
  subsection (e) below until the holder of such Certificate shall surrender
  such Certificate. Subject to the effect of applicable laws, following
  surrender of any such Certificate, there shall be paid to the holder of the
  certificates representing whole shares of Metzler Common Stock issued in
  exchange therefor, without interest, (i) at the time of such surrender, the
  amount of any cash payable in lieu of a fractional share of Metzler Common
  Stock to which such holder is entitled pursuant to subsection (e) below and
  the amount of dividends or other distributions with a record date after the
  Effective Time previously paid with respect to such whole shares of Metzler
  Common Stock, and (ii) at the appropriate payment date, the amount of
  dividends or other distributions with a record date after the Effective
  Time but prior to surrender and a payment date subsequent to surrender
  payable with respect to such whole shares of Metzler Common Stock.
 
    (d) No Further Ownership Rights in LECG Common Stock. All shares of
  Metzler Common Stock issued upon the surrender for exchange of shares of
  LECG Common Stock in accordance with the terms hereof (including any cash
  paid pursuant to subsection (c) or (e) of this Section 2.2) shall be deemed
  to have been issued in full satisfaction of all rights pertaining to such
  shares of LECG Common Stock, subject, however to the Surviving
  Corporation's obligation to pay any dividends or make any other
  distributions with a record date prior to the Effective Time which may have
  been declared or made by LECG on such shares of LECG Common Stock in
  accordance with the terms of this Agreement on or prior to the date hereof
  and which remain unpaid at the Effective Time and there shall be no further
  registration of transfers on the stock transfer books of the Surviving
  Corporation of the shares of LECG Common Stock which were outstanding
  immediately prior to the Effective Time. If, after the Effective Time,
  Certificates are presented to the Surviving Corporation, they shall be
  canceled and exchanged as provided in this Section 2.2.
 
    (e) No Fractional Shares. No certificate or scrip representing fractional
  shares of Metzler Common Stock shall be issued upon the surrender for
  exchange of Certificates, and such fractional share interests will not
  entitle the owner thereof to vote or to exercise any rights of a
  stockholder of Metzler. Notwithstanding any other provision of this
  Agreement, each holder of shares of LECG Common Stock exchanged pursuant to
  the Merger who would otherwise have been entitled to receive a fraction of
  a share
 
                                      A-7
<PAGE>
 
  of Metzler Common Stock (after taking into account all Certificates
  delivered by such holder) shall receive, in lieu thereof, cash (without
  interest) in an amount equal to such fractional part of a share of Metzler
  Common Stock multiplied by the last reported sale price of Metzler Common
  Stock, as reported on the Nasdaq National Market, on the trading day
  immediately preceding the date of the Effective Time.
 
    (f) Termination of Exchange Fund. Any portion of the Exchange Fund which
  remains undistributed to the shareholders of LECG for one year after the
  Effective Time shall be delivered to Metzler, and any shareholders of LECG
  who have not previously complied with this Section 2.2 shall thereafter
  look only to Metzler for payment of their claim for Metzler Common Stock,
  any cash in lieu of fractional shares of Metzler Common Stock, and any
  dividends or distributions with respect to LECG Common Stock or Metzler
  Common Stock.
 
    (g) No Liability. Neither Metzler nor LECG shall be liable to any holder
  of shares of LECG Common Stock or Metzler Common Stock, as the case may be,
  for such shares (or dividends or distributions with respect thereto)
  delivered to a public official as required by any applicable abandoned
  property, escheat or similar law.
 
  2.3. Dissenters' Rights. The shares of LECG Common Stock ("DISSENTERS'
SHARES") held by any shareholder of LECG who has exercised dissenters' rights
pursuant to the CGCL (a "DISSENTING SHAREHOLDER") shall not be converted
pursuant to the Merger unless and until the holder thereof shall have failed
to perfect or shall have effectively withdrawn or lost such holder's rights to
dissent from the Merger under the CGCL, and shall be entitled to receive only
the payment provided for by the CGCL. If any such holder shall fail to perfect
or shall have effectively withdrawn or lost the right to dissent, the
Dissenters' Shares held by such Dissenting Shareholder shall thereupon be
treated as though such shares had been converted into shares of Metzler Common
Stock pursuant to the terms hereof.
 
                                  ARTICLE 3.
 
                    Representations and Warranties of LECG
 
  LECG represents and warrants to Metzler and Sub that the statements
contained in this Article 3 are true and correct, except as set forth in the
disclosure schedule delivered by LECG to Metzler (the "LECG DISCLOSURE
SCHEDULE"). The LECG Disclosure Schedule shall be arranged in paragraphs
corresponding to the numbered and lettered paragraphs contained in this
Article 3, and the disclosure in any paragraph shall qualify only the
corresponding paragraph in this Article 3.
 
  3.1. Organization. Each of LECG and its Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the
respective jurisdiction of its incorporation, has all requisite corporate
power to own, lease and operate its property and to carry on its business as
now being conducted and as proposed to be conducted, and is duly qualified
and/or licensed to do business and is in good standing as a foreign
corporation in each jurisdiction in which the failure to be so qualified would
have a LECG Material Adverse Effect. Except as set forth on the LECG
Disclosure Schedule, neither LECG nor any of its Subsidiaries directly or
indirectly owns any equity or similar interest in, or any interest convertible
into or exchangeable or exercisable for, any corporation, partnership, joint
venture or other business association or entity, excluding securities in any
publicly traded company held for investment by LECG and comprising less than
one percent (1%) of the outstanding stock of such company.
 
  3.2. LECG Capital Structure.
 
    (a) The authorized capital stock of LECG consists of 40,000,000 shares of
  common stock, par value $0.001 per share ("LECG COMMON STOCK"), and
  5,000,000 shares of Preferred Stock, par value $0.001 per share ("LECG
  PREFERRED STOCK"). As of June 30, 1998, (i) 13,027,867 shares of LECG
  Common Stock were issued and outstanding, all of which are duly authorized,
  validly issued, fully paid and nonassessable, (ii) there were options
  outstanding under the LECG Stock Option Plans, entitling the
 
                                      A-8
<PAGE>
 
  optionees thereunder upon valid exercise to acquire in the aggregate
  608,300 shares of LECG Common Stock at a weighted average exercise price of
  $9.00 per share and (iii) no shares of LECG Common Stock were held by any
  Subsidiary of LECG. No change in such capitalization has occurred since
  such date other than the exercise and termination of stock options
  outstanding. No shares of LECG Preferred Stock were issued and outstanding.
  All shares of LECG Common Stock subject to issuance as specified above,
  upon issuance on the terms and conditions specified in the instruments
  pursuant to which they are issuable, shall be duly authorized, validly
  issued, fully paid and nonassessable. There are no obligations, contingent
  or otherwise, of LECG or any of its Subsidiaries to repurchase, redeem or
  otherwise acquire any shares of LECG Common Stock or the capital stock of
  any LECG Subsidiary or make any investment (in the form of a loan, capital
  contribution or otherwise) in any such Subsidiary or any other entity. All
  of the outstanding shares of capital stock of each of LECG's Subsidiaries
  are duly authorized, validly issued, fully paid and nonassessable and all
  such shares are owned by LECG free and clear of all Security Interests,
  agreements, preemptive rights, and/or limitations in LECG's voting rights,
  charges or other restrictions of any nature.
 
    (b) Except as set forth in this Section 3.2 or as reserved for future
  grants of options under the LECG Stock Option Plan or reserved for issuance
  pursuant to LECG's Stock Purchase Plan, there are no equity securities of
  any class of LECG or any of its Subsidiaries, or any security exchangeable
  into or exercisable for such equity securities, issued, reserved for
  issuance or outstanding. Except as set forth in this Section 3.2, there are
  no options, warrants, equity securities, calls, rights, commitments or
  agreements of any character to which LECG or any of its Subsidiaries is a
  party or by which any of them are bound obligating LECG or any of its
  Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or
  sold, additional shares of capital stock of LECG or any of its Subsidiaries
  or obligating LECG or any of its Subsidiaries to grant, extend, accelerate
  the vesting of or enter into any such option, warrant, equity security,
  call, right, commitment or agreement. None of the Existing Options that are
  not currently exercisable shall become exercisable as a result of the
  consummation of the Merger. To the knowledge of LECG, there are no voting
  trusts, proxies or other agreements or understandings with respect to the
  shares of capital stock of LECG. All of the outstanding LECG Common Stock,
  options or warrants were either registered under the Securities Act of
  1933, as amended (the "SECURITIES ACT") or were issued pursuant to valid
  exemptions from registration. LECG has taken all actions necessary such
  that after the Effective Time there will not exist any rights of any nature
  granting any Person a right to acquire the securities of LECG and/or its
  Subsidiaries.
 
  3.3. Authority and Status.
 
    (a) The execution, delivery and performance by LECG of this Agreement and
  each and every other agreement, document and instrument provided for herein
  have been duly authorized and approved by the Board of Directors of LECG
  subject only to the approval of the Merger by LECG's shareholders under
  applicable provisions of LECG's Articles of Incorporation and the CGCL. The
  Board of Directors of LECG has (i) determined that the Merger is fair to
  and in the best interests of the shareholders of LECG and (ii) resolved to
  submit the Merger to and recommend approval of the Merger by the
  shareholders of LECG.
 
    (b) LECG has the corporate power and authority to execute and deliver
  this Agreement, to perform hereunder and, upon approval of the transactions
  provided for herein by the shareholders of LECG, to consummate the
  transactions contemplated hereby without any other corporate or shareholder
  approval. Assuming this Agreement and each and every agreement, document or
  instrument to be executed, delivered and performed by LECG in connection
  herewith are valid and legally binding obligations of Metzler and Sub, this
  Agreement and each and every agreement, document and instrument to be
  executed, delivered and performed by LECG in connection herewith constitute
  or will, when executed and delivered, constitute the valid and legally
  binding obligation of LECG enforceable against it in accordance with their
  respective terms, except as enforceability may be limited by applicable
  equitable principles or by bankruptcy, insolvency, reorganization,
  moratorium, or similar laws from time to time in effect affecting the
  enforcement of creditors' rights generally. Attached hereto on the LECG
  Disclosure Schedule are true, correct and complete copies of the current
  Articles of Incorporation and Bylaws of LECG and each of its Subsidiaries.

  3.4. No Conflict; Required Filings and Consents.
 
    (a) The execution and delivery of this Agreement by LECG does not, and
  the consummation of the transactions contemplated by this Agreement will
  not, (i) conflict with, or result in any violation or breach of, any
  provision of the Articles of Incorporation or Bylaws of LECG; (ii) result
  in any violation or breach of, require any consent or approval under, or
  constitute (with or without notice or lapse of time, or both) a default (or
  give rise to a right of termination, cancellation or acceleration of any
  obligation or loss of any material benefit) under any of the terms,
  conditions or provisions of any material note, bond, mortgage, indenture,
  lease, contract or other agreement, instrument or obligation to which LECG
  or any of its Subsidiaries is a party or by which any of them or any of
  their properties or assets may be bound; or (iii) subject to the consents,
  approvals, orders, authorizations, filings and registrations specified in
  Section 3.4(b), conflict with or violate any permit, concession, franchise,
  license, judgment, order, decree, statute, law, ordinance, rule or
  regulation applicable to LECG or any of its Subsidiaries or any of their
  properties or assets.
 
    (b) Based on the representation of Metzler that neither the execution and
  delivery of this Agreement, nor the consummation of the transactions
  contemplated hereby would require Metzler to file a pre-merger notification
  report under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as
  amended, no consent, approval, order or authorization of, or registration,
  declaration or filing with, any court, administrative agency or commission
  or other governmental authority or instrumentality ("GOVERNMENTAL ENTITY")
  is required by or with respect to LECG or any of its Subsidiaries in
  connection with the execution and delivery of this Agreement or the
  consummation of the transactions contemplated hereby, except for (i) the
  filing and declaration of effectiveness of the Registration Statement (as
  defined in Section 3.23) with the Securities and Exchange Commission (the
  "SEC") in accordance with the Securities Act; (ii) the filing of the
  applicable Certificates of Merger with the California Department and the
  Delaware Department; (iii) the filing of the Proxy Statement (as defined in
  Section 3.23) with the SEC in accordance with the Securities Exchange Act
  of 1934, as amended (the "EXCHANGE ACT"); and (iv) such consents,
  approvals, orders, authorizations, registrations, declarations and filings
  as may be required under applicable federal and state securities laws.
 
  3.5. SEC Filings; Financial Statements.
 
    (a) LECG has filed and made available to Metzler all forms, each
  registration statement, schedule, report, proxy statement and document
  required to be filed by LECG with the SEC since October 16, 1997
  (collectively, the "LECG SEC REPORTS"). The LECG SEC Reports (i) at the
  time filed, complied in all material respects with the applicable
  requirements of the Securities Act and the Exchange Act, as the case may
  be, and (ii) did not at the time they were filed (or if amended or
  superseded by a filing prior to the date of this Agreement, then on the
  date of such filing) contain any untrue statement of a material fact or
  omit to state a material fact required to be stated in the LECG SEC Reports
  or necessary in order to make the statements in the LECG SEC Reports, in
  the light of the circumstances under which they were made, not misleading.
  None of LECG's Subsidiaries is required to file any forms, reports or other
  documents with the SEC. Since October 16, 1997, LECG has made all filings
  with the SEC in a timely manner as required by law and no event has
  occurred that requires an additional filing or any amendment to a prior
  filing.
 
    (b) Each of the consolidated financial statements (including, in each
  case, any related notes) contained in the LECG SEC Reports, including any
  LECG SEC Reports filed after the date of this Agreement until the Closing,
  complied or will comply as to form in all material respects with the
  applicable published rules and regulations of the SEC with respect thereto,
  was or will be prepared in accordance with generally accepted accounting
  principles applied on a consistent basis throughout the periods involved
  (except as may be indicated in the notes to such financial statements or,
  in the case of unaudited statements, as permitted for presentation in
  Quarterly Reports on Form 10-Q), and fairly presented or will fairly
  present the consolidated financial position of LECG and its Subsidiaries as
  at the respective dates and the consolidated results of their operations
  and cash flows for the periods indicated, except that the unaudited interim
 
                                     A-10
<PAGE>
 
  financial statements were or are subject to normal and recurring year-end
  adjustments which were not or are not material in amount. The audited
  balance sheet of LECG as of December 31, 1997 is referred to herein as the
  "LECG BALANCE SHEET."
 
    (c) LECG has provided Metzler with a consolidated balance sheet and
  related statements of income, changes in shareholder's equity and cash
  flows for LECG and each of its Subsidiaries as of and for the three month
  period ended March 31, 1998 ("LATEST BALANCE SHEET"). The Latest Balance
  Sheet and the related statement of income and cash flows are consistent
  with the accounting policies used in preparing the consolidated financial
  statements attached to the LECG SEC Reports and fairly present the results
  for the interim period presented thereby, except that such financial
  statements are subject to normal and recurring year-end adjustments which
  are not material in amount.
 
  3.6. Intentionally Omitted.
 
  3.7. Absence of Certain Changes or Events. Since the date of the LECG
Balance Sheet, LECG and its Subsidiaries have conducted their businesses only
in the ordinary course and in a manner consistent with past practice and,
since such date, there has not been (i) any material damage, destruction or
loss (whether or not covered by insurance) with respect to LECG or any of its
Subsidiaries; (ii) any change by LECG in its accounting methods, principles or
practices; (iii) any increase in dividends or employee compensation or
benefits payable by LECG, except for normal increases in compensation
consistent, in amounts and timing, with historical practices; (iv) any
revaluation by LECG of any of its assets, including, without limitation,
writing down the value of capitalized software or inventory or writing off
notes or accounts receivable other than in the Ordinary Course of Business;
(v) any change in any material respect in which the business of LECG and its
Subsidiaries has been conducted, including, without limitation, billing of
clients or collection of accounts receivable, purchases of goods and services
or payment of accounts payable; (vi) any agreement and/or understanding
entered into which alters or amends any licensing or contractual arrangements
with respect to any LECG Intellectual Property Rights, other than in the
Ordinary Course of Business; (vii) any loss or change in the relationships
with any client, contractor or supplier that would constitute a LECG Material
Adverse Effect; or (viii) any other transaction, commitment, dispute, or any
other action or event or condition that would be reasonably likely to have a
LECG Material Adverse Effect.
 
  3.8. Restrictions on Business Activities. There is no agreement, judgment,
injunction, order or decree binding upon LECG or any of its Subsidiaries which
has the effect of prohibiting or materially impairing any current or future
business practice of LECG or any of its Subsidiaries, any acquisition of
property by LECG or any of its Subsidiaries or the conduct of business by LECG
or any of its Subsidiaries as currently conducted or as proposed to be
conducted by LECG or any of its Subsidiaries.
 
  3.9. Taxes.
 
    (a) LECG and its Subsidiaries have, as of the date hereof, and will prior
  to the Effective Time have, timely and accurately filed all federal, state,
  foreign and local income, franchise, sales, real and personal property and
  other tax returns and reports required to be filed by them prior to such
  dates and have timely paid, or will prior to the Effective Time timely pay,
  all taxes shown on such returns as owed for the periods of such returns,
  including all withholding or other payroll related taxes shown on such
  returns. The tax basis of all assets of LECG and the Subsidiaries as
  reflected on their books and records is correct and accurate in all
  material aspects. Except as described on the LECG Disclosure Schedule,
  neither LECG nor any Subsidiary is, nor will any of them become, subject to
  any additional taxes, interest, penalties or other similar charges with
  respect to the tax returns and reports referred to in the first sentence of
  this Section 3.9(a) that would individually or in the aggregate have a LECG
  Material Adverse Effect. No assessments or notices of deficiency or other
  communications have been received by LECG, nor have any been threatened,
  with respect to any such tax return that has not been paid, discharged or
  fully reserved on the LECG Balance Sheet, and no amendments or applications
  for refund have been filed or are planned with respect to any such return.
  LECG does not have any material liabilities for Taxes that have not been
  accrued for or reserved on the LECG Balance Sheet, whether asserted or
  unasserted, contingent or otherwise. Except as
 
                                     A-11
<PAGE>
 
  set forth on the LECG Disclosure Schedule, there are no agreements between
  LECG or any Subsidiary and any taxing authority, including, without
  limitation, the IRS, waiving or extending any statute of limitations with
  respect to any tax return, and neither LECG nor any of its Subsidiaries has
  filed any consent or election under the Code, including, without
  limitation, any election under Section 341(f) of the Code.
 
    (b) Neither LECG nor any of its Subsidiaries has made any payments and
  none of them is obligated to make any payments, and none of them is a party
  to any agreement that under certain circumstances could obligate it, or any
  successor in interest, to make any parachute payments that will not be
  deductible under Section 280G of the Code.
 
    (c) LECG and its Subsidiaries (i) have withheld proper and accurate
  amounts in compliance with the tax withholding provisions of all applicable
  laws for all compensation paid to the officers and employees of LECG and
  its Subsidiaries, (ii) have correctly and properly prepared and duly and
  timely filed all returns and reports relating to those amounts withheld
  from their officers and employees and to their employer liability for
  employment taxes under the Tax Code and applicable state and local laws and
  (iii) have duly and timely paid and remitted to the appropriate taxing
  authorities the amounts withheld from their officers and employees and any
  additional amounts that represent their employer liability under applicable
  law for employment taxes.
 
    (d) To the knowledge of LECG, no issue has been raised by the IRS, any
  state or local taxing authority, or any other investigation or audit, that
  will have, or can be expected to have, a LECG Material Adverse Effect.
 
    (e) Neither LECG nor any of its Subsidiaries is a "United States real
  property holding corporation" as defined in Section 897(c)(2) of the Code.
 
  3.10. Intellectual Property.
 
    (a) LECG and its Subsidiaries own or use under valid fully paid licenses
  all patents, trademarks, trade names, service marks, copyrights and mask
  works, all applications for and registrations of such patents, trademarks,
  trade names, service marks, copyrights and mask works, and all processes,
  formulae, methods, schematics, technology, know-how, computer software
  programs or applications, algorithms, routines, and source code, and
  tangible or intangible proprietary information or material that are
  necessary to conduct the business of LECG and its Subsidiaries as currently
  conducted or planned to be conducted, excluding commercially available
  "shrink-wrap" and office automation software (the "LECG INTELLECTUAL
  PROPERTY RIGHTS").
 
    (b) There are no claims or demands, and to the knowledge of LECG no
  reasonable basis for any such claim or demand, of any Person that any of
  the LECG Intellectual Property Rights, or any processes or equipment used
  by LECG, any of the services of LECG or its Subsidiaries or any of the
  software or other proprietary rights or intellectual property developed by
  LECG or its Subsidiaries, infringes or conflicts in any way with any
  copyright, patent, trademark, service mark, trade name, trade secret,
  license, application or other proprietary right or intellectual property of
  any other Person, or makes unauthorized use of any secret process, formula,
  method, information, know-how or any other proprietary confidential
  information, including, without limitation, any software or software
  documentation, of any other Person. LECG or its Subsidiaries own all right,
  title and interest in and to the LECG Intellectual Property Rights, other
  than the items expressly identified as such on the LECG Disclosure
  Schedule, as to which LECG or its Subsidiaries has a valid, assignable
  license. Each of LECG's and its Subsidiaries' rights in and to such LECG
  Intellectual Property Rights are freely assignable in their respective own
  names, as applicable, including the right to create derivatives, and
  neither LECG nor any of its Subsidiaries is under any obligation to pay any
  royalty or other compensation to any third party or to obtain any approval
  or consent for use of licensing of any of the LECG Intellectual Property
  Rights. All of the interests of LECG and its Subsidiaries in the LECG
  Intellectual Property Rights are free and clear of all Security Interests,
  and are not currently being challenged or, to the knowledge of LECG
  infringed in any way or involved in any pending legal or
 
                                     A-12
<PAGE>
 
  administrative proceedings before any court or governmental agency. Except
  for licenses to clients in the Ordinary Course of Business, no current
  licenses for the use of any such rights have been granted by LECG or its
  Subsidiaries to any third parties, and to the knowledge of LECG none of the
  LECG Intellectual Property Rights is being used by any other Person.
 
    (c) It is the policy of LECG and its Subsidiaries to have each of their
  employees sign an employee nondisclosure and work-for-hire agreements
  substantially in the form attached to the LECG Disclosure Schedule. No
  employees or independent contractors of either LECG or any of its
  Subsidiaries have any valid claims or rights to any of the LECG
  Intellectual Property Rights. To the knowledge of LECG and its
  Subsidiaries, no employee of either LECG or any of its Subsidiaries is a
  party to or otherwise bound by any agreement with or obligated to any other
  Person (including, any former employer) which in any respect conflicts with
  any obligation, commitment or job responsibility of such employee to LECG
  or its Subsidiaries under any agreement to which currently he or she is a
  party or otherwise.
 
    (d) Neither LECG nor any of its Subsidiaries is or will be, as a result
  of the execution and delivery of this Agreement or the performance of its
  obligations under this Agreement, in breach of any license, sublicense or
  other agreement relating to the LECG Intellectual Property Rights or any
  license, sublicense or other agreement pursuant to which LECG or any of its
  Subsidiaries is authorized to use any third party patents, trademarks or
  copyrights, including software, which are used in the manufacture of,
  incorporated in, or form a part of any product of LECG or any of its
  Subsidiaries.
 
    (e) All patents, trademarks, service marks, copyrights, trade secrets and
  other proprietary rights held by LECG or any of its Subsidiaries which LECG
  considers to be material to its business are valid and enforceable. Neither
  LECG nor any of its Subsidiaries (i) is a party to any suit, action or
  proceeding which involves a claim of infringement of any patent, trademark,
  service mark or copyright or the violation of any trade secret or other
  proprietary right of any third party; or (ii) has any knowledge that the
  marketing, licensing, sale, offer for sale, or use of any of its services
  or products infringes any patent, trademark, service mark, copyright, trade
  secret or other proprietary right of any third party.
 
  3.11. Agreements, Contracts and Commitments. The LECG Disclosure Schedule
contains a true and complete list of all contracts, agreements, commitments
and other instruments (identified by title, date and parties) (whether oral or

  form), and any other contracts,

<PAGE>
 
  plans or commitments providing for any continuing payment of any type or
  nature, including, without limitation, any severance, termination,
  parachute, or other payments (whether due to a change in control,

    (g) any written arrangement concerning non-competition;

  consequences of a default or termination could have a LECG Material Adverse
  Effect;
 
    (i) agreements with any employee, the benefits of which are contingent
  on, or the terms of which are materially altered upon, the occurrence of a
  transaction of the nature contemplated by this Agreement involving LECG or
  its Subsidiaries; and
 
    (j) agreements or Plans the benefits of which will be increased or
  accelerated by the occurrence of the transactions contemplated by this
  Agreement.
 
  The contracts, agreements, commitments and other instruments listed or
required to be listed on the LECG Disclosure Schedule are herein referred to
as the "MATERIAL CONTRACTS."
 
  All the Material Contracts are valid and binding upon LECG or the applicable
Subsidiary and upon the other parties thereto and are in full force and effect
and enforceable in accordance with their terms, except as enforceability may
be affected by bankruptcy, insolvency, moratorium or similar laws affecting
creditors rights generally and general principles of equity relating to the
availability of equitable remedies. Except as set forth on the LECG Disclosure
Schedule, none of LECG, the applicable Subsidiary and any other party to any
such contract, commitment or arrangement has breached any provision of, or is
in default under, the terms thereof; and except as set forth on the LECG
Disclosure Schedule, there are no existing facts or circumstances that would
prevent the work in process of LECG or its Subsidiaries or their contracts and
agreements from maturing upon performance by LECG or its Subsidiaries into
accounts receivable collectible in the aggregate in amounts consistent in all
material respects with historical experience. Except as set forth on the LECG
Disclosure Schedule, there are no material contracts or commitments that
require the performance of services or provision of products by LECG at a
direct cost for each such contract or commitment reasonably expected to be in
excess of the revenue to be derived pursuant to the terms of such contract or
commitment. Except for terms specifically described on the LECG Disclosure
Schedule, neither LECG nor any Subsidiary has received any payment from any
contracting party in connection with or as an inducement for entering into any
contract, agreement, policy or instrument except for payment for actual
services rendered or to be rendered by LECG or its Subsidiaries consistent
with amounts historically charged for such services. Except for those Material
Contracts set forth on the LECG Disclosure Schedule and identified as "Fixed-
Rate Engagements" (the "MATERIAL FIXED-RATE ENGAGEMENTS"), neither LECG nor
its Subsidiaries is a party to any fixed fee or capped price contracts or
engagement arrangements involving work which if billed at LECG's normal hourly
rates would exceed $250,000 in annual revenues, nor does LECG or its
Subsidiaries have any outstanding offers, bids or proposals to perform any
services on a fixed fee or capped basis exceeding such amount. The LECG
Disclosure Schedule identifies each Material Fixed-Rate Engagement and sets
forth the number of hours remaining to complete the work required thereunder
and the amount of fees uncollected with respect thereto. The LECG Disclosure
Schedule also sets forth the amount of client payments to LECG or its
Subsidiaries through the date hereof with respect to services not yet
performed by LECG or its Subsidiaries, which payments individually or in the
aggregate exceed $100,000.
 
  3.12. Ownership of Assets. LECG and its Subsidiaries have title to all of
their respective properties and assets used or useful in their respective
businesses, other than leased property, licensed property and immaterial items
of personal property, in each case free and clear of any liens or Security
Interests, except as disclosed or
 
                                     A-14
<PAGE>
 
reserved against in the Latest Balance Sheet and except for liens arising from
current taxes not yet due and payable and other immaterial liens. Except as
disclosed on the LECG Disclosure Schedule, all material assets owned or leased
by LECG or any Subsidiary are in good operating condition and reasonable state
of repair, subject only to ordinary wear and tear. Neither LECG nor any
Subsidiary has received any notice of violation of any applicable zoning
regulation, ordinance or other law, regulation or requirement relating to
their operations and properties, whether owned or leased. All of the accounts
receivable of LECG and its Subsidiaries as of the Effective Time will reflect
actual transactions and will have arisen in the Ordinary Course of Business.
 
  3.13. Litigation. The LECG Disclosure Schedule sets forth each instance in
which LECG or any of its Subsidiaries (i) is subject to any unsatisfied
judgment, order, decree, stipulation, injunction or charge or (ii) is a party
to or, is threatened to be made a party to, any charge, complaint, action,
suit, proceeding, hearing, or investigation of or in any court or quasi-
judicial or administrative agency of any Federal, state, local, or foreign
jurisdiction or before any arbitrator. None of the charges, complaints,
actions, suits, proceedings, hearings, and investigations set forth on the
LECG Disclosure Schedule could reasonably be expected to result in any LECG
Material Adverse Effect. LECG has no knowledge of any basis on which such
charge, complaint, action, suit, proceeding, hearing, or investigation may be
brought or threatened against LECG or its Subsidiaries.
 
  3.14. Intentionally Omitted.
 
  3.15. Employees; Employment Matters.
 
    (a) Except as disclosed on the LECG Disclosure Schedule, neither LECG nor
  its Subsidiaries have any unsatisfied Liability to any previously
  terminated employee or independent contractor. LECG and its Subsidiaries
  have disclosed all written employee handbooks, policies, programs and
  arrangements to Metzler.
 
    (b) No key employee or group of employees has informed LECG and its
  Subsidiaries of any plans to terminate their employment with LECG or its
  Subsidiaries as a result of the transactions contemplated hereby or
  otherwise. Neither LECG nor its Subsidiaries are a party to or bound by any
  collective bargaining agreement and neither LECG nor its Subsidiaries have
  experienced any strikes, grievances, other collective bargaining disputes
  or claims of unfair labor practices. Neither LECG nor its Subsidiaries have
  any knowledge of any organizational effort presently being made or
  threatened by or on behalf of any labor union with respect to employees of
  LECG and its Subsidiaries.
 
    (c) All persons employed by LECG and its Subsidiaries are employees at
  will or otherwise employed such that LECG and its Subsidiaries may
  terminate their employment at any time, with or without cause, without
  creating any material cause of action against LECG and its Subsidiaries or
  otherwise giving rise to any material liability of LECG and its
  Subsidiaries for wrongful discharge, breach of contract or tort.
 
    (d) Except as disclosed on the LECG Disclosure Schedule, LECG and its
  Subsidiaries have complied in all material respects with all applicable
  laws relating to labor, including, without limitation, any requirements of
  the Immigration and Nationalization Act of 1952, as amended by the
  Immigration Reform and Control Act of 1986 and the regulations promulgated
  thereunder, any provisions thereof relating to wages, termination pay,
  vacation pay, fringe benefits, collective bargaining and the payment and/or
  accrual of the same and all insurance and all other costs and expenses
  applicable thereto, and neither LECG nor its Subsidiaries are liable for
  any arrearage, or any costs or penalties for failure to comply with any of
  the foregoing. Without limiting the generality of the foregoing, neither
  LECG nor its Subsidiaries have incurred a violation of Part 6 of Subtitle B
  of Title I of ERISA ("COBRA") or other applicable state insurance
  continuation law. No COBRA or other state insurance continuation law
  violation exists or will exist with respect to any employees of either LECG
  and its Subsidiaries prior to and including the Effective Time, nor will
  any such violation occur as a result of the transactions contemplated
  hereby.
 
    (e) Each Person whom LECG or its Subsidiaries has retained as an
  independent contractor during the past three years qualifies as an
  independent contractor and not as an employee of LECG or its Subsidiaries
  under the Code and all applicable state laws. Neither the execution of this
  Agreement nor the consummation of the transactions contemplated hereby
  shall cause LECG or its Subsidiaries to be in breach of any
 
                                     A-15
<PAGE>
 
  agreement with any employment, contractor or consultant or cause LECG or
  its Subsidiaries to be liable to pay any severance or other amount to any
  employee, contractor or consultant of LECG or its Subsidiaries.
 
  3.16. Employee Benefit Plans. LECG and each of its Plans have at all times
complied in all material respects with all applicable laws relating to labor
and employee benefits, including without limitation, all applicable provisions
of ERISA and the Code, any laws relating to wages, termination pay, vacation
pay, fringe benefits, collective bargaining and the payment and/or accrual of
the same and all taxes, insurance and all other costs and expenses applicable
thereto.
 
  3.17. Licenses and Permits; Compliance with Law. LECG and its Subsidiaries
hold all licenses, certificates, permits, franchises and rights from all
appropriate federal, state or other public authorities necessary for the
conduct of their respective businesses and the use of their respective assets,
except for such licenses, certificates, permits, franchises and rights the
absence of which would not individually or in the aggregate have a LECG
Material Adverse Effect. Except for any matters which will not have a LECG
Material Adverse Effect, LECG and its Subsidiaries presently are conducting
their respective businesses so as to comply with all applicable statutes,
ordinances, rules, regulations and orders of any governmental authority.
Further, LECG and its Subsidiaries are not presently charged with, or under
governmental investigation with respect to, any actual or alleged violation of
any statute, ordinance, rule or regulation, or presently the subject of any
pending or, to the knowledge of LECG, threatened adverse proceeding by any
regulatory authority having jurisdiction over their respective businesses,
properties or operations. Neither the execution and delivery of this Agreement
nor the consummation of the transactions contemplated hereby will result in
the termination of any license, certificate, permit, franchise or right held
by LECG or any of its Subsidiaries, and all such licenses, certificates,
permits, franchises and rights will inure to the benefit of the Surviving
Corporation after the consummation of the transactions contemplated by this
Agreement.
 
  3.18. Intentionally Omitted.
 
  3.19. Related Parties.
 
    (a) Except as set forth on the LECG Disclosure Schedule or in the LECG
  SEC Reports, to the knowledge of LECG, no shareholder owning greater than a
  five-percent (5%) interest in LECG, no Affiliate or member of the immediate
  family of any such shareholder, and no officer or director or member of the
  immediate family of such officer or director of LECG or any Subsidiary
  possesses, directly or indirectly, any beneficial interest in, or is a
  director, officer or employee of, or member of the immediate family of a
  director, officer or employee of, any corporation, partnership, firm,
  association or business organization that is a client, supplier, customer,
  lessor, lessee, lender, creditor, borrower, debtor or contracting party
  with or of LECG or any Subsidiary (except as a shareholder holding less
  than a one-percent (1%) interest in a corporation whose shares are traded
  on a national or regional securities exchange or in the over-the-counter
  market), other than arrangements with LECG principals and experts in the
  Ordinary Course of Business.
 
    (b) LECG has provided to each of its "Affiliates" as identified in
  Section 6.12 a copy of the Affiliates Letter and has obtained their
  agreement to execute and provide the Affiliates Letter to Metzler 31 days
  prior to the date of the LECG Shareholder Meeting.
 
  3.20. Pooling of Interests. LECG is not aware of any facts or circumstances
in respect of it or its accounting procedures, or transactions in its capital
stock, which would have the effect of precluding accounting for the
transactions contemplated hereby as a "pooling of interests."
 
  3.21. Complete Disclosure. No statement contained herein or in any
certificate, schedule, list, exhibit or other instrument furnished or required
to be furnished to Metzler pursuant to the provisions hereof contains, or will
at the time it is furnished contain, any untrue statement of any material fact
or omits or will omit to state any fact necessary to make the statements
herein or therein not false or misleading. As used in this Section, "material"
means material to the financial condition, business, properties, rights or
operations of LECG and its Subsidiaries, taken as a whole.
 
                                     A-16
<PAGE>
 
  3.22. No Special Shareholder Rights. Except as disclosed on the LECG
Disclosure Schedule, LECG has no agreement with any individual or entity that
grants such person any rights as a shareholder of LECG Common Stock that are
in addition to such holder's rights under LECG's Articles of Incorporation or
Bylaws (including, without limitation, registration rights, preemptive rights,
put rights, rights of co-sale or rights to Board representation).
 
  3.23. Registration Statement; Proxy Statement/Prospectus. The information
supplied by LECG for inclusion in the registration statement on Form S-4
pursuant to which shares of Metzler Common Stock issuable in the Merger will
be registered with the SEC (the "REGISTRATION STATEMENT") shall not at the
time the Registration Statement is declared effective by the SEC contain any
untrue statement of a material fact or omit to state any material fact
required to be stated in the Registration Statement or necessary in order to
make the statements in the Registration Statement, not misleading. The
information supplied by LECG for inclusion in the joint proxy
statement/prospectus (the "PROXY STATEMENT") to be sent to the shareholders of
LECG and the stockholders of Metzler in connection with the meetings of their
shareholders and stockholders, respectively, to consider this Agreement and
the Merger (the "LECG SHAREHOLDERS MEETING" and the "METZLER STOCKHOLDERS
MEETING," respectively, and, collectively, the "STOCKHOLDERS MEETINGS") shall
not, on the date the Proxy Statement is first mailed to shareholders of LECG
and the stockholders of Metzler, at the time of the Stockholders Meetings and
at the Effective Time, contain any statement which, at such time and in light
of the circumstances under which it was made, is false or misleading with
respect to any material fact, or omit to state any material fact necessary in
order to make the statements made in the Proxy Statement not false or
misleading, or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Stockholders Meetings which has become false or misleading. If
at any time prior to the Effective Time any event relating to LECG or any of
its Affiliates, officers or directors should be discovered by LECG which
should be set forth in an amendment to the Registration Statement or a
supplement to the Proxy Statement, LECG shall promptly inform Metzler.
 
  3.24. Intentionally Omitted.
 
  3.25. Intentionally Omitted.
 
  3.26. Suppliers and Clients. LECG shall provide Metzler with a true and
accurate list of (i) all of the clients that generated at least $250,000 in
revenues to LECG in any of the last three calendar years with whom LECG and
its Subsidiaries have had engagements since December 31, 1995 and (ii) a list
of all LECG clients with billings in 1998 in excess of $100,000. Since the
date of the LECG Latest Balance Sheet, no client of LECG and its Subsidiaries
accounting for more than 5% of LECG's revenues in fiscal 1997, has canceled,
materially reduced the scope of, or otherwise adversely modified its
relationship with LECG or its Subsidiaries and, no such Person has any
intention to do so, and there are no disputes or problems or notices of
dissatisfaction with or from any such client of LECG or its Subsidiaries and
the consummation of the transactions contemplated hereby will not, to the
knowledge of LECG, adversely affect any relationships with such clients.
 
  3.27. Warranty; Unbillable Work. All services rendered by LECG and its
Subsidiaries have been in material conformity with all applicable contractual
commitments and all warranties, and LECG and its Subsidiaries have no
Liability for damages in connection therewith, subject to the reserve for
client claims set forth on the face of the LECG Balance Sheet. LECG and its
Subsidiaries are not obligated to perform nonbillable client service work
(under the terms of the client agreement or necessary in order to maintain the
client relationship), in order to correct work previously performed that was
incorrect or deficient, to complete work in excess of the fixed rate limit
with respect to a particular project or otherwise, other than reasonable and
customary efforts to maintain client satisfaction consistent with the size and
scope of a particular project and consistent with maintaining the reasonable
profitability of such project.
 
  3.28. Year 2000 Compliance. LECG and its Subsidiaries have conducted a
reasonable review of all operating codes, programs, utilities and other
software as well as all hardware and systems utilized by LECG and its
Subsidiaries (collectively, "SYSTEMS") to determine whether such Systems are
designed to record, store,
 
                                     A-17
<PAGE>
 
process, and present calendar dates falling on or after January 1, 2000 in the
same manner, and with the same functionality, as provided on or before
December 31, 1999, and are designed to not lose functionality or degrade in
performance as a consequence of such software operating at a date later than
December 31, 1999 (such design and performance being referred to as "Y-2000
COMPLIANT"). To the extent such review identified Systems that are not Y-2000
Compliant, LECG and its Subsidiaries have taken, or are planning to take,
appropriate corrective action with respect to such Systems, and the costs of
such corrective action will not exceed, in the aggregate, $250,000.
 
                                  ARTICLE 4.
 
               Representations and Warranties of Metzler and Sub
 
  Metzler and Sub represent and warrant to LECG that the statements contained
in this Article 4 are true and correct, except as set forth in the disclosure
schedule delivered by Metzler to LECG (the "METZLER DISCLOSURE SCHEDULE"). The
Metzler Disclosure Schedule shall be arranged in paragraphs corresponding to
the numbered and lettered paragraphs contained in this Article 4, and the
disclosure in any paragraph shall qualify only the corresponding paragraph in
this Article 4.
 
  4.1. Organization. Each of Metzler, Sub and Metzler's other Subsidiaries is
a corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation, has all requisite corporate
power to own, lease and operate its property and to carry on its business as
now being conducted and as proposed to be conducted, and is duly qualified to
do business and is in good standing as a foreign corporation in each
jurisdiction in which the failure to be so qualified would have a Metzler
Material Adverse Effect. Except as set forth in the Metzler SEC Reports (as
defined in Section 4.4) or the Metzler Disclosure Schedule, neither Metzler
nor any of its Subsidiaries directly or indirectly owns any equity or similar
interest in, or any interest convertible into or exchangeable or exercisable
for, any corporation, partnership, joint venture or other business association
or entity, excluding securities in any publicly traded company held for

All shares of Metzler Common Stock subject to issuance as specified above,
upon issuance on the terms and conditions specified in the instruments
pursuant to which they are issuable, shall be duly authorized, validly issued,
fully paid and nonassessable. There are no obligations, contingent or
otherwise, of Metzler or any of its Subsidiaries to repurchase, redeem or
otherwise acquire any shares of Metzler Common Stock or the capital stock of
any Metzler Subsidiary. All of the outstanding shares of capital stock of each
of Metzler's Subsidiaries are duly authorized, validly issued, fully paid and
nonassessable and all such shares are owned by Metzler or a Subsidiary of
Metzler free and clear of all Security Interests, agreements, limitations in
Metzler's voting rights, charges or other restrictions of any nature.
 
  (b) Except as set forth in this Section 4.2 or as reserved for future grants
of options under the Metzler Option Plans or future sales under the Metzler
Purchase Plan, there are no equity securities of any class of Metzler or any

sell, or cause to be issued, delivered or sold, additional shares of capital
stock of Metzler or any of its respective Subsidiaries or obligating Metzler
or any of its respective Subsidiaries to grant, extend, accelerate the vesting
of or enter into any such option, warrant, equity security, call, right,
commitment or agreement. To the knowledge of Metzler, there are no voting
trusts, proxies or other agreements or understandings with respect to the
shares of capital stock of Metzler.
 
  4.3. Authority; No Conflict; Required Filings and Consents.
 
  (a) Metzler and Sub have all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated by
this Agreement. The execution and delivery of this Agreement and the

subject only to the approval of the shares to be issued in the Merger by
Metzler's shareholders under applicable provisions of the By-Laws of the
National Association of Securities Dealers, as amended. This Agreement has
been duly executed and delivered by Metzler and Sub and constitutes the valid
and binding obligation of Metzler and Sub, enforceable in accordance with its
terms, except as such enforceability may be limited by (i) bankruptcy laws and
other similar laws affecting creditors' rights generally and (ii) general
principles of equity, regardless of whether asserted in a proceeding in equity
or at law.

provision of the Certificate of Incorporation or Bylaws of Metzler or
certificate or Bylaws of Sub, (ii) result in any violation or breach of, or
constitute (with or without notice or lapse of time, or both) a default (or
give rise to a right of termination, cancellation or acceleration of any
obligation or loss of any material benefit) under any of the terms, conditions
or provisions of any note, bond, mortgage, indenture, lease, contract or other
agreement, instrument or obligation to which Metzler or any of its respective
Subsidiaries is a party or by which any of them or any of their properties or
assets may be bound, or (iii) subject to the consents, approvals, orders,
authorizations, filings and registrations specified in Section 4.3.(c),
conflict with or violate any permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to
Metzler or any of its respective Subsidiaries or any of their properties or
assets, except in the case of clause (ii) for any such violations, breaches,

would not be reasonably likely to have a Metzler Material Adverse Effect, or a
material adverse effect on the ability of Metzler or Sub to consummate the
transactions contemplated by this Agreement.
 
  (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Entity is required by or with

Effect or a material adverse effect on the parties' ability to consummate the
transactions contemplated by this Agreement.
 
  4.4. Sec Filings; Financial Statements.
 
  (a) Metzler has filed and made available to LECG all forms, reports and
documents required to be filed by Metzler with the SEC since July 26, 1996,
(collectively, the "METZLER SEC REPORTS"). The Metzler SEC Reports (i) at the

of the Securities
 
                                     A-19
<PAGE>
 
Act and the Exchange Act, as the case may be, and (ii) did not at the time
they were filed (or if amended or superseded by a filing prior to the date of
this Agreement, then on the date of such filing) contain any untrue statement
of a material fact or omit to state a material fact required to be stated in
the Metzler SEC Reports or necessary in order to make the statements in the
Metzler SEC Reports, in the light of the circumstances under which they were
made, not misleading.
 
  (b) Each of the consolidated financial statements (including, in each case,
any related notes) contained in the Metzler SEC Reports, including any Metzler
SEC Reports filed after the date of this Agreement until the Closing, complied
or will comply as to form in all material respects with the applicable
published rules and regulations of the SEC with respect thereto, was or will
be prepared in accordance with generally accepted accounting principles
applied on a consistent basis throughout the periods involved (except as may
be indicated in the notes to such financial statements or, in the case of
unaudited statements, as permitted for presentation in Quarterly Reports on
Form 10-Q), and fairly presented or will fairly present the consolidated
financial position of Metzler and its Subsidiaries as at the respective dates
and the consolidated results of its operations and cash flows for the periods
indicated, except that the unaudited interim financial statements were or are
subject to normal and recurring year-end adjustments which were not or are not
expected to be material in amount. The audited balance sheet of Metzler as of
December 31, 1997 is referred to herein as the "METZLER BALANCE SHEET."
 
  4.5. Absence of Certain Changes or Events. Since the date of the Metzler SEC
Reports there has not been any transaction, commitment, dispute or any other
event or condition that individually or in the aggregate constitutes a Metzler
Material Adverse Effect.
 
  4.6. Litigation. Except as described in the Metzler Disclosure Schedule,
there is no action, suit or proceeding, claim, arbitration or, to the
knowledge of Metzler, investigation against Metzler or any of its Subsidiaries
pending or as to which Metzler or any Subsidiary has received any written
notice of assertion. Except as disclosed in the Metzler Disclosure Schedule,
neither Metzler nor any of its Subsidiaries is subject to any outstanding
order, writ, injunction or decree which, insofar as can be reasonably
foreseen, individually or in the aggregate, would have a Metzler Material
Adverse Effect.
 
  4.7. Licenses and Permits; Compliance with Law. Metzler and its Subsidiaries
hold all licenses, certificates, permits, franchises and rights from all
appropriate federal, state or other public authorities necessary for the
conduct of their respective businesses and the use of their respective assets,
except for such licenses, certificates, permits, franchises and rights the
absence of which would not individually or in the aggregate have a Metzler
Material Adverse Effect. Except for any matters which will not have a Metzler
Material Adverse Effect, Metzler and its Subsidiaries presently are conducting
their respective businesses so as to comply with all applicable statutes,
ordinances, rules, regulations and orders of any governmental authority.
Further, Metzler and its Subsidiaries are not presently charged with, or under
governmental investigation with respect to, any actual or alleged violation of
any statute, ordinance, rule or regulation, or presently the subject of any
pending or, to the knowledge of Metzler, threatened adverse proceeding by any
regulatory authority having jurisdiction over their respective businesses,
properties or operations. Neither the execution and delivery of this Agreement
nor the consummation of the transactions contemplated hereby will result in
the termination of any license, certificate, permit, franchise or right held
by Metzler or any of its Subsidiaries, and all such licenses, certificates,
permits, franchises and rights will inure to the benefit of the Surviving
Corporation after the consummation of the transactions contemplated by this
Agreement.
 
  4.8. Pooling of Interests. Metzler is not aware of any facts or
circumstances in respect of it or its accounting procedures which would have
the effect of precluding accounting for the transactions contemplated hereby
as a "pooling of interests."
 
  4.9. Registration Statement; Proxy Statement/Prospectus. The information
supplied by Metzler (including information concerning Sub) for inclusion in
the Registration Statement shall not at the time the Registration Statement is
declared effective by the SEC contain any untrue statement of a material fact
or omit to state any material fact required to be stated in the Registration
Statement or necessary in order to make the statements in
 
                                     A-20
<PAGE>
 
the Registration Statement, not misleading. The information supplied by
Metzler (including information concerning Sub) for inclusion in the Proxy
Statement shall not, on the date the Proxy Statement is first mailed to the
shareholders of LECG and the stockholders of Metzler, at the time of the
Stockholders' Meetings and at the Effective Time, contain any statement which,
at such time and in light of the circumstances under which it was made, is
false or misleading with respect to any material fact, or omit to state any
material fact necessary in order to make the statements made in the Proxy
Statement not false or misleading, or omit to state any material fact
necessary to correct any statement in any earlier communication with respect
to the solicitation of proxies for the Stockholders' Meetings which has become
false or misleading. If at any time prior to the Effective Time any event
relating to Metzler or any of its Affiliates, officers or directors should be
discovered by Metzler which should be set forth in an amendment to the
Registration Statement or a supplement to the Proxy Statement, Metzler shall
promptly inform LECG.
 
  4.10. Complete Disclosure. No statement contained herein or in any
certificate, schedule, list, exhibit or other instrument furnished or required
to be furnished to LECG pursuant to the provisions hereof contains, or will at
the time it is furnished contain, any untrue statement of any material fact or
omits or omit to state any fact necessary to make the statements herein or
there not false or misleading. As used in this Section, "material" means
material to the financial condition, business, properties, rights or
operations of Metzler and its Subsidiaries, taken as a whole.

  exercise of Existing Options;
 
    (c) Declare or pay any dividends on or make any other distributions
  (whether in cash, stock or property) in respect of any of its capital

    (h) Incur any Indebtedness for borrowed money or guarantee any such
  Indebtedness or issue or sell any debt securities or warrants or rights to
  acquire any debt securities or guarantee any debt securities of others,
  other than Indebtedness incurred under outstanding lines of credit in the
  Ordinary Course of Business;
 
    (i) Incur or commit to incur aggregate capital expenditures in an amount

  the date made (to the extent so limited) or as of the Effective Time.
 
  5.2. Cooperation. Subject to compliance with applicable law, from the date
hereof until the Effective Time, each of Metzler and LECG shall confer on a
regular and frequent basis with one or more representatives of the other party
to report operational matters of materiality and the general status of ongoing
operations and shall promptly provide the other party or its counsel with
copies of all filings made by such party with any Governmental Entity in
connection with this Agreement, the Merger and the transactions contemplated
hereby.
 
  5.3. Pooling Treatment. Neither Metzler nor LECG, nor any of their
respective Subsidiaries, shall take any action that would adversely affect the
ability of the parties hereto to account for the business combination to be
effected by the Merger as a pooling of interests.

                             Additional Agreements
 
  6.1. No Solicitation.
 
  (a) LECG shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, through any officer, director, employee,
representative, agent or affiliate, (i) solicit, initiate, or encourage
(including by way of furnishing information) any inquiries or proposals that
constitute, or could reasonably be expected to lead to, a proposal or offer
for a merger, consolidation, business combination, sale of substantial assets,
sale of shares of capital stock (including without limitation by way of a
tender offer) or similar transactions involving LECG, other than the
transactions contemplated or permitted by this Agreement (any of the foregoing
inquiries or proposals being referred to in this Agreement as a "COMPETING
OFFER"), (ii) engage in negotiations or discussions concerning, or provide any
non-public information to any Person relating to, any Competing Offer, or
(iii) agree to, approve or recommend any Competing Offer. Neither the Board of
Directors of LECG, nor any committee thereof, shall (a) withdraw or modify, or
propose to withdraw or modify, in any manner adverse to Metzler, the approval
or recommendation of the Board of Directors of LECG of the Merger or this
Agreement, or (b) approve or recommend, or propose to approve or recommend,
any Competing Offer or any other acquisition of outstanding shares of LECG,
other than pursuant to the Merger or this Agreement. Notwithstanding the
foregoing, nothing contained in this Agreement shall prevent LECG or its Board
of Directors from (A) furnishing non-public information to, or entering into
discussions or negotiations with, any Person in connection with an unsolicited
bona fide written Competing Offer by such Person (including a new and
unsolicited Competing Offer received by LECG after the execution of this
Agreement from a Person whose initial contact with LECG may have been
solicited by such party prior to the execution of this Agreement) or
recommending such an unsolicited bona fide written Competing Offer to its
shareholders, if and only to the extent that (1) (x) the LECG Board of
Directors determines in good faith (after consultation with and based upon the
written advice of its financial advisor, if any) that such Competing Offer
would, if consummated, result in a transaction more favorable to LECG's
shareholders than the transaction contemplated by this Agreement and that the
Person making such Preferred Proposal has the financial means, or the ability
to obtain the necessary financing, to conclude such transaction, and (y) the
Board of Directors of LECG determines in good faith (after consultation with
and based upon the written advice of its outside legal counsel) that the
failure to take such action would be inconsistent with the fiduciary duties of
the Board of Directors to its shareholders under applicable law (any such more
favorable Competing Offer being referred to in this Agreement as a "PREFERRED
PROPOSAL"); and (2) prior to furnishing such non-public information to, or
entering into discussions or negotiations with, such Person, the Board of
Directors receives from such Person an executed confidentiality agreement with
confidentiality provisions not materially less favorable to such Person than
those contained in the Confidentiality Agreement dated as of May 15, 1998
between Metzler and LECG (the "CONFIDENTIALITY AGREEMENT") or (B) complying
with Rule 14e-2 promulgated under the Exchange Act with regard to a Competing
Offer. LECG shall take no action with respect to the Competing Offer until 48
hours after notice is received by Metzler as required under Section 6.1(b)
below.
 
  (b) LECG shall notify Metzler orally and in writing no later than 24 hours
after receipt by LECG (or its advisors) of any Competing Offer or any request
for nonpublic information in connection with a Competing Offer or for access
to the properties, books or records of such party by any Person that informs
such party that it is considering making, or has made, a Competing Offer. Such
notice to Metzler shall be made orally and in writing and shall indicate in
reasonable detail the identity of the offeror and the terms and conditions of
such proposal, inquiry or contact.

Metzler shall prepare and file with the SEC the Registration Statement in

best efforts to cause the Registration Statement to become effective as soon
after such filing as practicable, and the parties shall promptly
 
                                     A-23

furnish a copy of the Proxy Statement/prospectus included in the Registration

Merger under the Securities Act and the Exchange Act and applicable state blue
sky laws and the rules and regulations thereunder.

material agreements, contracts, licenses or leases as may be necessary or
advisable to consummate the Merger and the other transactions contemplated by
this Agreement.
 
  6.4. Access to Information. Upon reasonable notice and subject to applicable
law and other legal obligations, LECG shall afford to the officers, employees,

its properties, books, contracts, commitments, personnel and records and,
during such period, LECG shall furnish promptly to Metzler (a) a copy of each
report, schedule, registration statement and other document filed or received
by it during such period pursuant to the requirements of federal securities
laws and (b) all other information concerning its business, properties and
personnel as Metzler may reasonably request. Unless otherwise required by law,
the parties will hold any such information which is nonpublic in confidence in
accordance with the Confidentiality Agreement. No information or knowledge
obtained in any investigation pursuant to this Section 6.4 shall affect or be
deemed to modify any representation or warranty contained in this Agreement or
the conditions to the obligations of the parties to consummate the Merger.
 
  6.5. Stockholders Meetings. LECG and Metzler shall each call a meeting of
their respective shareholders and stockholders, as applicable, to be held as
promptly as practicable for the purpose of voting upon this Agreement and the
Merger, with respect to LECG, and the issuance of the shares of Metzler Common
Stock contemplated hereunder, with respect to Metzler. Subject to Sections 6.1
and 6.2, LECG and Metzler will, through their respective Boards of Directors,
recommend to their respective shareholders and stockholders, as applicable,
approval of such matters and will coordinate and cooperate with respect to the
timing of such meetings and shall use their best efforts to hold such meetings
on the same day and as soon as practicable after the date hereof.
 
  6.6. Legal Conditions to Merger. Each of Metzler and LECG will take all
reasonable actions necessary to comply promptly with all legal requirements
which may be imposed on itself with respect to the Merger (which actions shall
include, without limitation, furnishing all information required in connection
with approvals of or filings with any Governmental Entity) and will promptly
cooperate with and will use their best efforts to furnish information to each
other in connection with any such requirements imposed upon any of them in
connection with the Merger. Each of Metzler and LECG will: (i) take all
reasonable actions necessary to obtain (and will cooperate with each other in
obtaining) any consent, authorization, order or approval of, or any exemption
by, any Governmental Entity or other third party, required to be obtained or
made by LECG or Metzler in connection with the Merger (any of the foregoing an
"APPROVAL") or the taking of any action contemplated thereby or by this
Agreement; (ii) diligently oppose or pursue any rehearing, appeal or other
challenge which may be available to it of any refusal to issue any Approval or
of any order or ruling of any Governmental Entity which may adversely affect
the ability of the parties hereto to consummate the Merger or to take any
action contemplated by any Approval or by this Agreement until such time as
such refusal to issue any Approval or any order or ruling has become final and
non-appealable; and (iii) diligently oppose any objections to, appeals from or
petitions to reconsider or reopen any Approval or the taking of any action
contemplated thereby or by this Agreement.
 
  6.7. Public Disclosure. In the event that either party proposes to issue,
make or distribute any press release, public announcement or other written
publicity or disclosure prior to the Closing Date that refers to the
transactions contemplated herein, the party proposing to make such disclosure
shall provide a copy of such disclosure to the other parties and shall afford

cause the business combination to be effected by the Merger to be accounted
for as a pooling of interests. Each of Metzler and LECG shall use its best

avoid any action that would adversely affect the ability of Metzler to account
for the business combination to be effected by the Merger as a pooling of
interests.
 
  6.10. Letters from Accountants.
 
  (a) LECG shall use its best efforts to cause to be delivered to Metzler

comparable in scope and substance to letters customarily delivered by
independent public accountants in connection with registration statements

form and substance reasonably satisfactory to LECG and comparable in scope and

until the Effective Time, each party hereto shall promptly notify the other
party, by written update to its Disclosure Schedule, of (i) the occurrence or
non-occurrence of any event which would be likely to cause any condition to
the obligations of any party to effect the Merger and the other transactions
contemplated by this Agreement not to be satisfied, or (ii) the failure of
Metzler or LECG to comply with or satisfy any covenant, condition or agreement
to be complied with or satisfied by it pursuant to this Agreement which would
be likely to result in any condition to the obligations of any party to effect
the Merger and the other transactions contemplated by this Agreement not to be
satisfied. The delivery of any notice pursuant to this Section 6.11 shall not
cure any breach of any representation or warranty requiring disclosure of such
matter prior to the date of this Agreement or otherwise limit or affect the
remedies available hereunder to the party receiving such notice, provided that
such party, within ten (10) Business Days after receipt of such notice,
advises the other party of its objection to the matter disclosed in such
notice and the nature of such objection.
 
  6.12. Affiliate Letter. Upon the execution of this agreement, Metzler and

LECG shall provide each other such information and documents as LECG or
Metzler shall reasonably request for purposes of reviewing such list and shall
notify the other party in writing regarding any change in the identity of its
Affiliates prior to the Closing Date. LECG shall use its best efforts to

  written notice before recommending such Competing Offers to its
  shareholders; or
 
    (h) by LECG, if a breach of any representation, warranty, covenant or

  or agreement hereunder, such covenant or agreement is incapable of being
  cured or, if capable of being cured, shall not have been cured within

  such breach from Metzler; or
 
    (i) by Metzler if LECG's revenues, margins and earnings per share, as
  reported for the three months ended June 30, 1998, shall be less than the
  estimates for such period previously provided to Metzler by LECG, or by
  LECG if Metzler's revenues, margins and earnings per share, as reported for

having a fair market value equal to more than forty percent (40%) of the fair
market value of all the consolidated assets of such party immediately prior to
such transaction or series of transactions; or (iv) any transaction or series
of transactions pursuant to which any Third Party acquires or would acquire

regulations promulgated thereunder, unless the context requires otherwise. The
parties intend that each representation, warranty and covenant contained

representation, warranty or covenant contained herein in any respect, the fact
that there exists another representation, warranty or covenant relating to the
same subject matter (regardless of the relative levels of specificity) which
the party has not breached shall not detract from or mitigate the fact that
the party is in breach of the first representation, warranty, or covenant.

comparable meaning whether used in a masculine, feminine or gender-neutral

  9.5. Governing Law. This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware without regard to any
applicable conflicts of law rules. If any provision of this Agreement is held
to be unenforceable for any reason, it shall be modified rather than voided,
if possible, in order to achieve the intent of the parties to the extent
possible. In any event, all other provisions of this Agreement shall be deemed
valid and enforceable to the extent possible.
 
  9.6. Assignment. Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto (whether
by operation of law or otherwise) without the prior written consent of the
other parties, and any attempted assignment thereof without such consent shall
be null and void. Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of and be enforceable by the parties and
their respective successors and assigns.
 
  9.7. Entire Agreement; No Third Party Beneficiaries. This Agreement and all
agreements referenced specifically in this Agreement and executed as required
by this Agreement constitute the entire agreement among the parties hereto and
supersede and cancel any prior agreements, representations, warranties, or
communications, whether oral or written, among the parties hereto relating to
the transactions contemplated hereby or the subject matter herein. Neither
this Agreement nor any provision hereof may be changed, waived, discharged or
terminated orally, but only by an agreement in writing signed by the party
against whom or which the enforcement of such change, waiver, discharge or
termination is sought. This Agreement is not intended to confer upon any
person other than the parties hereto any rights or remedies hereunder.
 
  9.8. No Agreement Until Executed. This Agreement shall not constitute or be
deemed to evidence a contract or agreement among the parties hereto unless and
until executed by all parties hereto, irrespective, of negotiations among the
parties or the exchanging of drafts of this Agreement.
 
  9.9. Severability. In the event that any court or any governmental authority
or agency declares all or any part of any Section of this Agreement to be
unlawful or invalid, such unlawfulness or invalidity shall not serve to
invalidate any other Section of this Agreement, and in the event that only a
portion of any Section is so declared to be unlawful or invalid, such
unlawfulness or invalidity shall not serve to invalidate the balance of such
Section.

of Merger signed on behalf of each of Acquisition Sub and the Company, shall be
duly prepared, executed and acknowledged by the Company, Acquisition Sub and
such other parties as may be appropriate, and thereafter such Articles of Merger
shall be delivered to the Secretary of State of the State of Illinois (the

defined). The Acquisition shall become effective for corporate law issues at
5:00 p.m. Chicago time on the date such filings occur (the "Merger Time"). The
date on which the Merger Time occurs is referred to herein as the "Merger Date".

     2.2.  Closing.  The closing of the transactions contemplated hereby (the
"Closing") will take place at the offices of Barack Ferrazzano Kirschbaum
Perlman & Nagelberg, 333 West Wacker Drive, Suite 2700, Chicago, Illinois 60606,
on August 31, 1998, to the extent that the conditions set forth in Sections 4.5
and 4.6 have been satisfied or waived (where permissible), unless another time
or place is agreed to by the Parties. The effective date of this transaction
will be the date of Closing (the "Effective Date"). At the Closing, the Parties
shall make delivery of those materials set forth, respectively, in Sections 4.5
and 4.6 hereof.

     2.3.  Effects of the Merger.

          (a)  At the Merger Time, the separate legal existence of Acquisition
Sub shall cease and Acquisition Sub shall be merged with and into the Company
and the Company, as the surviving entity in the Acquisition (the "Surviving
Entity"), shall continue its legal existence under the laws of the State of
Illinois under the name "Peterson Consulting L.L.C." doing business as "Peterson
Worldwide L.L.C."

          (b)  At and after the Merger Time, the Acquisition will have the
effects set forth in Article 37 of the ILLCA.

     2.4.  Articles of Organization and Operating Agreement.  The Articles of
Organization and the Operating Agreement of Acquisition Sub, in substantially
the form set forth as Exhibit A hereto, each as in effect immediately prior to

Operating Agreement of the Surviving Entity immediately after the Merger Time
and shall thereafter continue to be its Articles of Organization and the
Operating Agreement until amended as provided therein and under the ILLCA.

<PAGE>
 
     2.5.  Directors and Officers.  The manager of Acquisition Sub holding
office immediately prior to the Merger Time shall be the manager of the
Surviving Entity immediately after the Merger Time. Immediately after the Merger
Time, the officers of the Surviving Entity shall be the officers of Acquisition
Sub holding office immediately prior to the Merger Time and the officers listed
on Schedule 2.5 hereto.

     2.6.  Conversion of Securities.  At the Merger Time, by virtue of the
Acquisition and without any action on the part of Acquisition Sub, the Company
or the Members, (x) the outstanding interests in equity securities of
Acquisition Sub held by Metzler immediately prior to the Merger Time shall be
converted into a 100% membership interest in the Company, and (y) the Membership
Interest held by the Members immediately prior to the Merger Time shall be
converted into shares of Metzler Common based on the Metzler Common Value as set
forth on Schedule 2.6 attached hereto; provided, however, that those Members who
dissent from the Acquisition shall receive, in lieu of Metzler Common, cash in
an amount equal to their Pro Rata Percentage of the Total Transaction Value;
and, further, provided, that if as the result of the conversion of any Member's
Membership Interests upon consummation of the Acquisition, a fractional interest
in a share of Metzler Common would be deliverable under this Section 2.6, in
lieu of a fractional share being delivered therefor, such fractional interest
shall automatically be converted into the right to receive an amount in cash
(without interest) equal to the product of the Metzler Common Value multiplied
by the amount of such fractional interest. No such holder will be entitled to
dividends, voting rights or any other rights as a shareholder of Metzler in
respect of any fractional share. For all purposes of this Agreement (including
all computations pursuant to Schedule 2.6, the Total Transaction Value shall be
adjusted in accordance with the following provisions:

          (a)  Closing Balance Sheet.  As soon as practicable but no later than
45 days following the Closing Date, the Company Managers shall deliver to
Metzler a balance sheet (the "Closing Balance Sheet") for the Company dated as
of the close of business the day prior to the date of Closing (the "Closing
Balance Sheet Date"), which Closing Balance Sheet shall be prepared by the
Company and reviewed by Crowe Chizek and Company LLP ("Crowe Chizek") and shall
set forth the assets and liabilities of the Company as of the close of business
on the Closing Balance Sheet Date. The Closing Balance Sheet shall present
fairly the financial position of the Company as of the Closing Balance Sheet
Date, in accordance with GAAP (the "Interim Financial Statement Standards").

               (i) If Metzler determines to dispute in good faith that the
     Closing Balance sheet has not been prepared in accordance with the Interim
     Financial Statement Standards, Metzler shall notify the Member's
     Representative in writing thereof (the "Metzler Notice") within 14 days
     after delivery to the Metzler of the Closing Balance Sheet (the "Notice
     Period"). The Metzler Notice shall set forth in reasonable detail the
     alleged non-conformance and the amount(s) being disputed. If Metzler does
     not deliver the Metzler Notice within the Notice Period, the Closing
     Balance Sheet shall become final and binding upon all parties.

<PAGE>
 
               (ii) If the Metzler Notice is delivered within the Notice Period,
     the Members' Representative and Metzler shall attempt in good faith to
     resolve all dispute(s). If Metzler and the Members are unable to resolve
     any disputed item within 14 days after receipt of the Metzler Notice, such
     disputed item(s), together with each party's calculation of the Company's
     Working Capital, Total Assets and Net Members' Capital (in each case, as
     defined below) as of the Closing Balance Sheet Date, shall be submitted to
     a nationally recognized "Big Five" accounting firm or its successor (other
     than the Company's or Metzler's regular auditors or their successors)
     chosen by lot, which accounting firm shall be instructed to arbitrate such
     disputed item(s) and determine the Company's Working Capital, Total Assets
     and Net Members' Capital as of the Closing Balance Sheet Date. The
     resolution of disputes by the accounting firm so selected shall be set
     forth in writing and shall be conclusive and binding upon all parties and
     adjustment may be entered thereon by any court having jurisdiction over the
     parties. The costs of such resolution by such accounting firm shall be
     borne one half by the Members, in proportion to their respective Pro Rata
     Percentages, on the one hand, and one half by Metzler, on the other hand.

               (A) The term "Working Capital" means the excess of the Company's
          current assets over its current liabilities as of the Closing Balance
          Sheet Date, calculated in accordance with the Interim Financial
          Statement Standards, all as finally determined in accordance with this
          Section 2.6(a).

               (B) The term "Total Assets" means the Company's total assets,
          calculated in accordance with the Interim Financial Statement
          Standards, all as finally determined in accordance with this Section
          2.6(a).

               (C) The term "Net Members' Capital" means the excess of the
          Company's total assets over its total liabilities as of the Closing
          Balance Sheet Date, calculated in accordance with the Interim
          Financial Statement Standards, all as finally determined in accordance
          with this Section 2.6(a).

          (b)  Adjustment.  The Total Transaction Value shall be adjusted
downward, on a dollar-for-dollar basis and in accordance with this paragraph
(b), to account for the negative differential (the "Target Differential"), if
any, between Target Working Capital, Target Total Assets, and Target Net
Members' Capital (as each such term is hereafter defined) and each of,
respectively, Working Capital, Total Assets, and Net Members' Capital. For
purposes hereof, the Target Differential shall be the greater of the respective
differentials between (a) Target Working Capital and Working Capital, (b) Target
Total Assets and Total Assets, and (c) Target Net Members' Capital and Net
Members' Capital. Target Working Capital shall be $11,000,000, Target Total
Assets shall be $39,000,000, and Target Net Members' Capital shall be
$20,000,000. As of the Merger Date, an amount of shares of Metzler Common equal
to 10% of the number of shares of Metzler Common issued pursuant to the
Acquisition shall be deposited with the Escrow Agent and held in a segregated
escrow account (the "Adjustment Escrow") in accordance with the terms of the
Escrow Agreement. Within three days following the determination of the Target
Differential, if any, the Escrow Agent shall return to Metzler the

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

inducement to Metzler and Acquisition Sub to enter into this Agreement and
consummate the transactions contemplated hereby, the Company and the Company
Managers hereby jointly and severally represent and warrant to Metzler and
Acquisition Sub that all of the statements contained in this Section 3.1 are
correct and complete as of the date of this Agreement, and hereby covenant that
said statements will be correct and complete as of the Merger Date (as though

the date of this Agreement throughout such statements), except, in each case, as
set forth in the schedule attached to this Agreement setting forth exceptions to
the representations and

                                       10

warranties set forth herein (the "Disclosure Schedule"). The Disclosure Schedule
will be arranged in sections corresponding to the numbered and lettered sections
contained in this Section 3.1, and no matter disclosed with respect to one
section shall be deemed to be an exception to another section unless the
applicability of such item to such other section is reasonably apparent.
Notwithstanding anything herein to the contrary, the disclosure of any contract
agreement, arrangement or understanding herein shall not affect or qualify any
representation with respect to the effectiveness or enforceability of such
contract, agreement, arrangement or understanding or the absence of breaches or
defaults thereunder, unless otherwise specifically disclosed.

          (a)  Organization, Qualification and Corporate Power.  The Company is
a limited liability company duly organized, validly existing and in good
standing under the laws of the State of Illinois. Each Subsidiary of the

organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation, as identified in Section 3.1(a) of the Disclosure
Schedule. Each of the Company and its Subsidiaries has all requisite limited
liability company or corporate power, as the case may be, and authority to carry
on the business in which it is engaged and to own and use the properties owned
and used by it. True and correct copies of the Company's Articles of
Organization and Operating Agreement, in each case as amended to date, have been
delivered to Metzler. Each of the Company and its Subsidiaries is qualified to
conduct business and is in good standing under the laws of each jurisdiction
wherein the nature of its business or its ownership of property requires it to
be so qualified, except where the failure to be so qualified, would not
individually or in the aggregate, have a Material Adverse Effect. Section 3.1(a)
of the Disclosure Schedule lists all jurisdictions in which the Company and each
of its Subsidiaries is qualified to do business.

          (b)  Authorization of Transaction.  The Company has all requisite
limited liability company power and authority to execute and deliver this
Agreement and to perform its obligations hereunder. Without limiting the
generality of the prior sentence, the Board of Managers of the Company have duly
authorized the execution, delivery and performance of this Agreement and the
consummation of the Acquisition. This Agreement constitutes the valid and
legally binding obligation of the Company enforceable against the Company in
accordance with its terms, except as enforceability may be limited by (i)
bankruptcy, insolvency, reorganization, moratorium, or other similar laws now or
hereafter in effect relating to the rights and remedies of creditors generally
or (ii) general principles of equity.

          (c)  Noncontravention.  Subject to compliance with the HSR Act and
except as set forth on Section 3.1(c) of the Disclosure Schedule, neither the
execution and the delivery of this Agreement, nor the consummation of the
transactions contemplated hereby will (i) violate any applicable statute,
regulation, law, rule or common law doctrine, (ii) violate any judgment, order,

Security Interest upon any of the Company's (or any of its Subsidiaries') assets
pursuant to the terms of, any contract, agreement, lease, sublease, license,
sublicense, franchise, permit, indenture, agreement for borrowed money,
instrument of indebtedness, Security Interest or other binding arrangement to
which the Company (or any of its Subsidiaries) is a party or by which it is
bound or to which any of its assets are subject, except, in the case of clauses
(i) and (iv) above, for those violations or breaches which would not,
individually or in the aggregate, have a Material Adverse Effect. Except
pursuant to the HSR Act and as set forth on Section 3.1(c) of the Disclosure
Schedule, the Company is not required to give any notice to, make any material
filing with, or obtain any authorization, consent, or approval of any
government, governmental agency or court, or any other Person in order for the
parties to consummate the Acquisition and the transactions contemplated by this
Agreement or in order that the Acquisition and such transactions not constitute
a breach or violation of, or result in a right of termination or acceleration or
any encumbrance on any of the Company's (or any of its Subsidiaries') assets,
pursuant to the provisions of any material agreement, arrangement or
understanding or any material license, franchise or permit.

solely of the Membership Interests, all of which are owned by the Members. Set
forth on Section 3.1(d) of the Disclosure Schedule is a true and correct
description of (i) the full legal names, current address and social security
number of each owner of Membership Interests, (ii) the Pro Rata Percentage of
each of the Members, and (iii) all of the current managers and officers of the
Company. None of the Membership Interests are evidenced or represented by any
certificate or comparable writing. The Company has never authorized, offered,
sold or issued any securities other than Membership Interests. All offerings,
sales and issuances by the Company of any Membership Interests have been
conducted in compliance with and in accordance with or in reliance upon
exemptions from all applicable Federal and state securities laws and all other
applicable state laws. Except as set forth on Section 3.1(d) of the Disclosure
Schedule, there are no currently outstanding or authorized options, warrants,
rights, contracts, rights of first refusal or first offer, calls, puts, rights

Company is a party or which are binding upon the Company or any of the Members
providing for the issuance, disposition, or acquisition of any Membership
Interests or securities convertible into or exchangeable for Membership
Interests. There are no voting trusts, proxies, or any other agreements,
restrictions or understandings with respect to the voting of any of the
Membership Interests, except for those agreements expressly contemplated hereby.

          (f)  Financial Statements; Books and Records.

               (i) The Company has provided Metzler with the following financial
     statements, correct and complete copies of which are set forth on Section
     3.1(f) of the Disclosure Schedule (collectively the "Financial
     Statements"): (A) consolidated and consolidating balance sheet and related
     statements of income and changes in members' equity for the Company as of
     and for the fiscal years ended December 31, 1997, 1996 and 1995 (December
     31, 1997 being the "Most Recent Fiscal Year End"), each audited by Crowe
     Chizek and (B) unaudited consolidated and consolidating balance sheet and
     related statements of income for the Company as of and for the three months
     ended June 30, 1998 and year to date (the "Latest Financials"). The
     Financial Statements are correct and complete in all material respects and
     have been prepared in accordance with GAAP, except, in the case of the
     Latest Financials, for the absence of footnotes and normal year-end
     adjustments. The Financial Statements fairly present, on such basis, the
     consolidated financial condition and results of operations of the Company
     and its Subsidiaries as of the times and for the periods referred to
     therein.

               (ii) The Company's and its Subsidiaries' books and records are
     and have been properly prepared and maintained in form and substance
     adequate for preparing audited financial statements in accordance with
     GAAP, and fairly and accurately reflect in all material respects all of the
     assets and Liabilities of the Company and its Subsidiaries and all
     contracts and transactions to which the Company or any of its Subsidiaries
     is or was a party or by which the Company or any of its Subsidiaries or any
     of their respective business or assets is or was affected. The minute books
     and related records of the Company and its Subsidiaries, correct and
     complete copies of which have been made available to Metzler, correctly
     reflect in all material respects all resolutions adopted and all other
     material corporate actions taken at all meetings or through consents of the
     managers or directors (including committees thereof) and the members or
     shareholders.

     to do any of the foregoing.

          (h)  Undisclosed Liabilities.  Neither the Company nor any of its
Subsidiaries has any Liability (and there is no Basis for any present or future
charge, complaint, action, suit, proceeding, hearing, investigation, claim, or
demand against the Company or any of its Subsidiaries giving rise to any
Liability), except for (i) Liabilities set forth on the face of the Latest
Financials, (ii) Liabilities (since June 30, 1998) in the Ordinary Course of
Business (none of which relates to any breach of contract, breach of warranty,
tort, infringement, or violation of law or arose out of any charge, complaint,
action, suit, proceeding, hearing, investigation, claim, or demand), (iii)
Liabilities in an aggregate amount of less than $10,000, and (iv) Liabilities
otherwise expressly disclosed in this Agreement or on the Disclosure Schedule
(it being understood that except as set forth in Section 3.1(f) no
representation or warranty is being made regarding the revenues or results of
operations of the Company).

          (i)  Tax Matters.

               (i) Each of the Company and its Subsidiaries (including IDR) has
     filed all Tax Returns that it was required to file on or prior to the date
     hereof. All such Tax Returns were true, correct and complete in all
     material respects and accurately reflected all Liability for Taxes for the
     periods covered thereby and, with respect to any Member, accurately
     reflected information necessary for such Member to determine his, her, or
     its Liability for unpaid Taxes. The Liability of the Company and its
     Subsidiaries for unpaid Taxes, whether to any governmental authority or to
     another Person such as under a tax sharing agreement, for all periods
     ending on or before the Merger Date do not exceed the amount of the
     Liability accruals for Taxes (excluding reserves for deferred Tax assets or
     deferred Tax Liabilities) on the Latest Financials. To the Knowledge of the
     Company, neither the Company nor any of the Subsidiaries have received
     notice of any claim made by an authority in a jurisdiction where the
     Company or any of its Subsidiaries do not file Tax Returns that any of the
     Company and its Subsidiaries is or may be subject to taxation by that
     jurisdiction. There are no Security Interests on any of the assets of the
     Company that arose in connection with any failure (or alleged failure) to
     pay any Tax when due.

               (ii) The Company and its Subsidiaries have withheld and paid when
     due all Taxes required to have been withheld and paid in connection with
     amounts paid or owing to any employee, creditor, independent contractor, or
     other third party.

                                       15
<PAGE>
 
               (iii) The Company has no Knowledge of any Basis on which any
     taxing authority could assess any additional Taxes for any period for which
     Tax Returns have been filed. There is no dispute or claim concerning any
     Tax Liability of the Company, of any of its Subsidiaries or of any Member
     relating to the Company or any of its Subsidiaries either (A) claimed or
     raised by any taxing authority in writing or (B) as to which the Company
     has Knowledge. The Company has previously provided to Metzler correct
     copies of all Federal, state, local, and foreign Tax Returns filed with
     respect to the Company and its Subsidiaries for the prior three year end
     periods. None of such Tax Returns have been audited by a government or
     taxing authority, nor is subject to any audit or other Tax Proceeding in
     process, pending, or threatened (either in writing, or verbally, formally
     or informally) or are expected to be asserted with respect to Taxes (or the
     collection of Taxes) of any of the Company, its Subsidiaries, or a Member
     (to the extent such Taxes relate to the Company or any of its
     Subsidiaries). There are no examination reports or statements of
     deficiencies assessed against or agreed to by the Company, any of its
     Subsidiaries or any of its Members relating to the Company or any of its
     Subsidiaries for such taxable periods.

               (iv) Neither the Company nor any of its Subsidiaries has filed a
     consent under Section 341(f) of the Code concerning collapsible
     corporations. Neither the Company nor any of its Subsidiaries has made any
     material payments, is obligated to make any material payments, or is a
     party to any agreement that would obligate it to make any material payments
     that will not be deductible under Section 280G of the Code. Neither the
     Company nor any of its Subsidiaries has been a United States real property
     holding corporation within the meaning of Section 897(c)(2) of the Code
     during the applicable period specified in Section 897(c)(A)(ii) of the
     Code. Neither the Company nor any of its Subsidiaries is a party to any tax
     allocation or sharing agreement. Neither the Company nor any of its
     Subsidiaries has been a member of an Affiliated Group which filed federal
     income tax returns, other than a group of which the Company was the common
     parent. Neither the Company nor any of its Subsidiaries has any Liability
     for Taxes owed by any Person (other than the Company), including without
     limitation, (A) as a transferee, assignee or other successor or (B)
     pursuant to a Tax sharing agreement or other contract.

               (v) Neither the Company nor any of its Subsidiaries has waived
     any statute of limitations in respect of Taxes or agreed to any extension
     of time with respect to any Tax assessment or deficiency.

          (j)  Title and Condition of Properties.

               (i) Neither the Company nor any of its Subsidiaries owns any real
     property.

               (ii) The leases described in Section 3.1(j) of the Disclosure
     Schedule (the "Property Leases") cover all of the real estate leased, used
     or occupied by the Company or any of its Subsidiaries. Each of the Property
     Leases is in full force and

                                       16
<PAGE>
 
     effect and the Company or one of its Subsidiaries holds a valid and
     existing leasehold or subleasehold interest under each of such Property
     Leases. The Company has delivered to Metzler complete and accurate copies
     of each of the Property Leases and none of such Property Leases has been
     modified in any material respect, except to the extent that such
     modifications are disclosed by the copies delivered to Metzler. Neither the
     Company nor any of its Subsidiaries is in default, and to the Knowledge of
     the Company no circumstances exist which would result in such default
     (including upon the giving of notice or the passage of time, or both),
     under any of such Property Leases, and no other party thereto has the right
     to terminate, accelerate performance under or otherwise modify any of such
     leases. To the Knowledge of the Company, no lessor under any such lease is
     in default under any of such leases in its duties to the lessee. Except as
     set forth in Section 3.1(j) of the Disclosure Schedule, neither the Company
     nor any of its Subsidiaries has assigned, transferred, conveyed, subjected
     to a Security Interest, or otherwise encumbered any interest in any of the
     Property Leases.

               (iii) The Company or one of its Subsidiaries owns good and
     marketable title, free and clear of all Security Interests, to all of the
     personal property and assets reflected on the Latest Financials or acquired
     after June 30, 1998, except for (A) assets with an aggregate original
     purchase price of less than $100,000 which have been disposed of to non-
     affiliated third parties since June 30, 1998, in the Ordinary Course of
     Business, (B) Security Interests securing liabilities reflected on the
     Latest Financials and (C) Security Interests for current Taxes not yet due
     and payable.

               (iv) The Company's computer hardware, equipment and other
     tangible personal property and assets are in good condition and repair,
     except for ordinary wear and tear not caused by neglect, and are useable
     for their respective intended purposes in the Ordinary Course of Business.
     The personal property and assets shown on the Latest Financials or acquired
     after June 30, 1998, the lease rights under the Property Leases and leases
     of personal property and the Intellectual Property owned or used by the
     Company or any of its Subsidiaries under valid license, collectively
     include all assets necessary to the conduct of the Company's and its
     Subsidiaries business as presently conducted. None of the Members, other
     employees or independent contractors of the Company or their respective
     Affiliates owns any rights, other than as would exist upon liquidation or
     distribution of the Company, in any material assets, real or personal,
     which are used by the Company or any of its Subsidiaries in its business.

     Intellectual Property which are owned, licensed by, licensed to, used or
     held for use in or necessary for the conduct of the business of the Company
     or any of its Subsidiaries as such business is currently conducted and
     presently contemplated

                                       17

     to be conducted, or as to which the Company or any of its Subsidiaries has
     a contractual right to an assignment.

               (ii) No Person has any Security Interest (other than the right to
     use Software under license) in the Company's or any of its Subsidiaries'
     interest in any Intellectual Property owned by the Company or any of its
     Subsidiaries. The Company and each of its Subsidiaries has all rights to
     use the Intellectual Property owned or used by it in the manner in which
     such Intellectual Property is currently being used. Neither the Company nor
     any of its Subsidiaries is under any obligation to pay any royalty or other
     compensation to any third party or to obtain any approval for use of any of
     the Intellectual Property. To the Knowledge of the Company, none of the
     Intellectual Property is subject to any outstanding judgment, order,
     decree, stipulation, injunction or charge; no charge, complaint, action,
     suit, proceeding, hearing, investigation, claim, or demand is pending or,
     to the Knowledge of the Company, threatened, which challenges the legality,
     validity, enforceability, use or ownership of any of the Intellectual
     Property.

               (iii) No breach or default (or event which with notice or lapse
     of time or both would result in a breach or default) by the Company or any
     of its Subsidiaries exists or has occurred under any material License-In or
     other material agreement pursuant to which the Company or any of its
     Subsidiaries uses any Intellectual Property, and the consummation of the
     transactions contemplated by this Agreement will not violate or conflict
     with or constitute a breach or default (or an event which, with notice or
     lapse of time or both, would constitute a breach or default) or result in a
     forfeiture under, or constitute a Basis for termination of, any such
     License-In or such other agreement or impair the Company's or any of its
     Subsidiaries' ability after consummation of the Acquisition to use the
     Software in the same manner as such Software is currently used by the
     Company or such Subsidiary, except where such breaches, defaults,
     violations, conflicts or other events which would not, individually or in
     the aggregate, result in a Material Adverse Effect.

               (iv) Each of the Company and its Subsidiaries owns or has the
     right to use all the Intellectual Property necessary to provide, produce,
     sell and license the services and products currently provided, produced,
     sold and licensed by the Company or any of its Subsidiaries, and to conduct
     the Company's or any of its Subsidiaries' business as presently conducted,
     and the consummation of the transactions contemplated hereby will not alter
     or impair any such rights, including any right of the Company or any of its
     Subsidiaries to use or sublicense any Intellectual Property owned by
     others. The Intellectual Property includes all patents, trademarks, trade
     names, service marks, copyrights, mask work rights and trade secrets, and
     the Software includes all software, which are necessary to operate the
     business of the Company and each of its Subsidiaries as it is presently
     conducted and to satisfy and perform the contracts, commitments,
     arrangements and understandings with customers of the Company and each of
     its Subsidiaries. The Company has no Knowledge of any reason the Company
     and each of its Subsidiaries will not be able to continue to own, possess
     or have access to, and to use, license and sub-license as applicable, on
     reasonable terms, all Intellectual Property and

                                       18

     other proprietary rights necessary for the lawful conduct of its business
     as presently conducted and currently contemplated to be conducted, without
     any infringement or conflict with the rights of others.

               (v) No Intellectual Property owned by the Company or any of its
     Subsidiaries, and no product or service practiced, offered, licensed or
     sold by the Company or any of its Subsidiaries, infringes or, to the
     Knowledge of the Company, is being infringed by any trademark, trade name,
     copyright, trade secret, patent, right of publicity, right of privacy or
     other proprietary right of any Person or would give rise to an obligation
     to render an accounting to any Person as a result of co-authorship, co-
     invention or an express or implied contract for any use or transfer.
     Neither the Company nor any of its Subsidiaries has received notice of any
     adversely held patent, invention, trademark, copyright, service mark, trade
     name or trade secret of any other Person alleging or threatening to assert
     that the Company's or any of its Subsidiaries' use of any of the
     Intellectual Property infringes upon or is in conflict with any
     intellectual property or proprietary rights of any third party.  The
     Company, has no Knowledge of any Basis for any claim, threatened claim or
     any suit or action asserting any such infringement or conflict or asserting
     that the Company or any of its Subsidiaries does not have the legal right
     to own, enforce, sell, license, sublicense, lease or otherwise use any such
     Intellectual Property, process, product or service, and the Company has no
     Knowledge of any facts which should give such Person reason to believe that
     there exists any Basis for such claim, threatened claim or suit or that any
     such claim, threatened claim or suit may be asserted or instituted in the
     future.

               (vi) Neither the Company nor any of its Subsidiaries has sent or
     otherwise communicated to any other Person any notice, charge, claim or
     assertion of, and the Company has no Knowledge of any present, impending or
     threatened infringement by any other Person of any Intellectual Property
     owned by the Company or any of its Subsidiaries.

               (vii) Except as disclosed in Section 3.1(k) of the Disclosure
     Schedule, all the Company's and each of its Subsidiaries' Patents,
     Trademarks and Copyrights listed in Section 3.1(k) of the Disclosure
     Schedule as having been issued by, registered with or filed with the United
     States Patent and Trademark Office or Register of Copyrights or the
     corresponding offices of other countries identified in Section 3.1(k) of
     the Schedule have been so duly registered, filed in or issued, as the case
     may be, and have been properly maintained and renewed in accordance with
     all applicable provisions of law and administrative regulations in the
     United States and each such other country.  The Company and each of its
     Subsidiaries has used reasonable efforts to protect its rights in the
     Intellectual Property.  The Company or one of its Subsidiaries owns all
     right, title and interest in and to the Intellectual Property, other than
     the Software listed on Exhibit 2 to Section 3.1(k) Disclosure Schedule, as
     to which the Company has a valid license.  No current licenses for the use
     of the Intellectual Property requires the Company or any of its
     Subsidiaries to apply for or enforce appropriate legal protection of such
     licensed Intellectual Property.

               (viii) Each of the Company's and each of its Subsidiaries'
     current or former employees and those current or former independent
     contractors retained by the Company or any of its Subsidiaries who, either
     alone or in concert with others, created or creates, developed or develops,
     invented or invents, discovered or discovers, derived or derives,
     programmed or programs or designed or designs any of the Intellectual
     Property, has entered into a written agreement with the Company or any of
     its Subsidiaries, copies of which have heretofore been furnished to
     Metzler.  No former employees or independent contractors of the Company or
     any of its Subsidiaries have any claims or rights to any of the
     Intellectual Property necessary for the conduct of the Company's or any of
     its Subsidiaries' business as now conducted.  To the Knowledge of the
     Company, no employee of the Company or any of its Subsidiaries is a party
     to or otherwise bound by any agreement with or obligated to any other
     Person (including, any former employer) which in any respect conflicts with
     any obligation, commitment or job responsibility of such employee to the
     Company or one of its Subsidiaries under any agreement to which currently
     he or she is a party or otherwise.

               (ix) Exhibit 3 to Section 3.1(k) of the Disclosure Schedule
     identifies each Person to whom the Company or any of its Subsidiaries has
     sold, licensed, leased or otherwise transferred or granted any interest or
     rights to any Intellectual Property, other than Intellectual Property
     licensed to end users pursuant to standard, non-exclusive "shrink wrap"
     license agreements in the Ordinary Course of Business, none of which is a
     license of any source code ("Shrink Wrap Licenses").  The Company has
     previously delivered to Metzler complete and accurate copies of all
     agreements relating to each such sale, license, lease or other transfer or
     grant.  The Company has delivered to Metzler copies of all copyright and
     trademark registration certificates and all letters patent.

               (x) The Company has documented all of the Software owned by it or
     any of its Subsidiaries and used in its or any of its Subsidiaries'
     business in sufficient detail that a reasonably competent computer
     professional conversant with the language in which such Software written
     using such documentation alone, would be able to understand, support and
     modify such Software.  To the Knowledge of the Company and the Members, all
     of the data used in the Software was obtained from public sources and is
     not subject to any confidentiality obligation imposed on the Company.

               (xi) To its Knowledge, neither the Company nor any of its
     Subsidiaries has not taken any actions under the law of any applicable
     foreign jurisdictions where the Company or any of its Subsidiaries has
     marketed or licensed Software that would restrict or limit the ability of
     the Company or any of its Subsidiaries to protect, or prevent it from
     protecting, its ownership interests in, confidentiality rights of, and
     rights to market, license, modify or enhance the Software.

               (xii) Neither the Company nor any of its Subsidiaries has
     granted any third party the right to market the Company's or any of its
     Subsidiaries' Software.

          (l) Contracts.  Except as set forth on Schedule 3.1(l), with respect
to each written agreement that would be material to the Company and its
Subsidiaries as a whole (a "Material Contract"): (A) the Material Contract is
in full force and effect; (B) the Material Contract will continue to be in full
force and effect on identical terms immediately after the Merger Date; (C)
neither the Company nor any of its Subsidiaries (nor, to the Knowledge of the
Company, any other party) is in material breach or default (including, with
respect to any express or implied warranty), and no event has occurred which
with notice or lapse of time or both would constitute a material breach or
default or permit termination, modification, or acceleration, under any Material
Contract, except for any breaches, defaults, terminations, modifications or
accelerations which have been cured or waived; and (D) to the Knowledge of the
Company, no party has repudiated any material provision of any such Material
Contract.  To the Knowledge of the Company, neither the Company nor any of its
Subsidiaries is a party to any verbal contract, agreement, or other arrangement
which, if reduced to written form, would be a Material Contract.  Correct and
complete copies of the general forms of client engagement and services used by
the Company and each of its Subsidiaries have been made available to Metzler.
Except for those Material Contracts set forth on Section 3.1(l) of the
Disclosure Schedule, neither the Company nor any of its Subsidiaries is a party
to any fixed fee or capped price contracts or engagement arrangements (the
"Fixed Rate Engagements"), nor does the Company nor any of its Subsidiaries have
any outstanding offers, bids or proposals to perform any services on a fixed fee
or capped basis in an amount in excess of $1,500,000 per year.  With respect to
the Company's Fixed Rate Engagements, the ratio of the amount of revenues
recognized to date (in the aggregate) by the Company compared to the amount of
revenues payable thereunder is reasonably proportionate to the ratio of the
amount of work completed under such Fixed Rate Engagements to the work required
thereunder.

          (m) Notes and Accounts Receivable.  All notes and accounts receivable
of the Company and each of its Subsidiaries are reflected properly on its books

counterclaims, are current and collectible in the aggregate amount shown, and
will be collected in accordance with their terms at their recorded amounts,
subject only to the reserve for bad debts set forth on the face of the Latest
Financials, as adjusted for operations and transactions through the Merger Date
in accordance with the past custom and practice of the Company and its
Subsidiaries.  Since June 30, 1998, there has not been an adverse change of more
than 10% in the aggregate amount of the accounts receivable of the Company or
any of its Subsidiaries or an increase of the average age of such receivables of
15 days.

          (n) Intentionally Omitted.

          (o) Litigation.  Section 3.1(o) of the Disclosure Schedule sets forth
each instance in which the Company or any of its Subsidiaries (i) is subject to
any unsatisfied judgment, order, decree, stipulation or injunction or (ii) is a
party to or, to the Knowledge of the Company, is threatened to be made a party
to, any complaint, action, suit, proceeding, hearing, or investigation of or in
any court or quasi-judicial or administrative agency of any Federal, state,
local, or foreign jurisdiction or before any arbitrator for an amount in
controversy in excess of $100,000 individually or $250,000 in the aggregate.
None of the

complaints, actions, suits, proceedings, hearings, and investigations set forth
in Section 3.2(o) of the Disclosure Schedule could reasonably be expected to
result in any Material Adverse Effect. To the Knowledge of the Company, there
does not exist a Basis on which any such complaint, action, suit, proceeding,
hearing, or investigation may be brought or threatened against the Company or
any of its Subsidiaries that could have a Material Adverse Effect on the
Company.

          (p) Employees; Employment Matters.

     collective bargaining agreement, and neither the Company nor any of its
     Subsidiaries has experienced any strikes, grievances, other collective
     bargaining disputes or, to the Knowledge of the Company, claims of unfair
     labor practices.  The Company has no Knowledge of any organizational effort
     presently being made or threatened by or on behalf of any labor union with
     respect to employees of the Company or any of its Subsidiaries.

               (ii) Section 3.1(p) of the Disclosure Schedule contains a true,
     correct and complete list setting forth the names and current salaries or
     rates of compensation of all employees of the Company and each of the
     Subsidiaries with an annual base salary of at least $50,000 and independent
     contractors who render services to the Company or any of its Subsidiaries
     on more than a single occasion who are expected to be paid at least $50,000
     in 1998.  Except as disclosed on Section 3.1(p) of the Disclosure Schedule,

     Schedule, all Persons employed by the Company and each of its Subsidiaries
     are employees at will.  Except as set forth in Section 3.1(p) of the
     Disclosure Schedule, none of the employees of the Company or any of its
     Subsidiaries are subject to noncompete/nonsolicitation covenants in favor
     of the Company.

               (iv) The Company and each of its Subsidiaries has materially
     complied with all applicable laws relating to labor, including, without
     limitation, any provisions thereof relating to wages, termination pay,

     accrual of the same and all Taxes, insurance and all other costs and
     expenses applicable thereto, and neither the Company 

                                       22

     nor any of its Subsidiaries is liable for any material arrearage, or any
     Taxes, costs or penalties for failure to comply with any of the foregoing.
     Without limiting the generality of the foregoing, neither the Company nor
     any of its Subsidiaries has incurred a violation of Part 6 of Subtitle B of
     Title I of ERISA ("COBRA") or other applicable state insurance continuation
     law. No material COBRA or other state insurance continuation law violation
     exists or will exist with respect to any employees of the Company or any of
     its Subsidiaries prior to the Merger Date.

     or any of its Subsidiaries currently retains as an independent contractor
     or previously retained as an independent contractor qualifies, or at all
     times while performing services for the Company or any of its Subsidiaries
     qualified, as an independent contractor and not as an employee of the
     Company or any of its Subsidiaries, under the Code and all applicable state
     laws.  Neither the execution of this Agreement nor the consummation of the
     Acquisition shall cause the Company or any of its Subsidiaries to be in
     breach of any agreement with any employee, contractor or consultant or
     cause the Company or any of its Subsidiaries to be liable to pay any
     severance or other amount to any of its employees, contractors or
     consultants.

          (q) Employee Benefit Plans.

               (i) All Plans of the Company and each of its Subsidiaries which
     are "employee benefit plans" within the meaning of Section 3(3) of ERISA
     are listed in Section 3.1(q) of the Disclosure Schedule.  Each Plan is in
     material compliance with its terms and with ERISA and other applicable laws
     (including, without limitation, compliance with the health care
     continuation requirements of COBRA and any proposed regulations promulgated
     thereunder), and all agreements and instruments applicable to any Plan.
     Section 3.1(q) of the Disclosure Schedule sets forth each former employee
     of the Company or any of its Subsidiaries entitled to COBRA benefits and
     the remaining period of such benefits.  The Company has received favorable
     determination letters as to the qualification under the Code of each Plan
     which is a pension plan, as defined in Section 3(2) of ERISA ("Pension
     Plan"), and, to the Company's Knowledge, there have been no amendments or,
     to the Company's Knowledge, other developments since the date of such
     determination letters which would cause the loss of such qualified status.
     No material violation of ERISA has occurred within the last 6 years in
     connection with the administration of any of the Plans, and there are no
     actions, suits, or claims (other than routine, non-contested claims for
     benefits) pending or threatened against the Plans, or any administrator or
     fiduciary thereof, which could result in any material Liability.

     heretofore made available to Metzler true and complete copies of each of
     the following to the extent such documents exist or are applicable:

There is and has been no material violation of ERISA known to the Company with
respect to the filing of applicable reports, documents, and notices regarding
such past or present Plans with the Secretary of Labor or the Secretary of the
Treasury or the furnishing of such documents to the participants or
beneficiaries of such Plans.

               (iii) Except as disclosed in Section 3.1(g) of the Disclosure
     Schedule, each Plan maintained by the Company is maintained under a plan
     document which does not provide for other participating employers except
     for the Company or any ERISA Affiliate of the Company and no Plan provides
     or has provided credit with respect to service other than with the Company
     or any ERISA Affiliate of the Company.

               (iv) Neither the Company nor any ERISA Affiliate of the Company
     nor any of their employees, shareholders, or directors has engaged in any
     transaction in connection with which any of them would be subject either to
     a civil penalty assessed pursuant to Section 502 of ERISA or a tax imposed
     by Section 4975 of the Code, other than transactions which would not,
     individually or in the aggregate, have a Material Adverse Effect on the
     Company.  The execution and performance of this Agreement will not involve
     any prohibited transaction within the meaning of Section 406 of ERISA,
     other than transactions which would not, individually or in the aggregate,
     have a Material Adverse Effect on the Company.

               (v) None of the assets of any of the Plans is or has been

     such Plans as of the last day of the most recent fiscal year prior to the
     Merger Date.

               (viii) The execution and performance of this Agreement will not
     constitute a stated triggering event under any Plan or employment agreement
     that will result in any material payment (whether of severance pay or
     otherwise) becoming due to any employee of the Company or ERISA Affiliate
     of the Company.

               (ix) Neither the Company nor any ERISA Affiliate of the Company
     provides, nor have they at any time provided, coverage under any welfare
     plan  (a Welfare Plan (as defined in Section 3(l) of ERISA) (including, but
     not limited to, life insurance, disability, medical, dental, prescription
     drugs, or accidental death or dismemberment) to any of their retirees,
     other than any continuation or conversion coverage which any such retiree
     may have purchased at his own expense, or a defined benefit plan (as
     defined in Section 3(35) of ERISA).

     of the most recent plan year for which such statements are available, and
     the list of the investments of such Pension Plan as of the most recent plan

     financial conditions of the Pension Plans as of the date of such
     statements, and there have been no material changes in such investments
     between such date and the Merger Date.

     either written or oral, or communications made or materials provided to any
     employee or former employee of the Company or any ERISA Affiliate of the
     Company by any officer, director, employee, agent or representative of the
     Company that provide for or could be construed as a contract or promise by
     the Company or any ERISA Affiliate of the Company to provide for any
     pension, welfare, or other insurance-type benefits to such employee or
     former employee, whether before or after retirement, other than benefits
     under the Plans.

               (xii) Neither the Company nor any ERISA Affiliate of the Company
     currently contributes, or at any time in the past has contributed to a
     defined benefit plan (as defined in Section 3(35) of ERISA), including, but
     not limited to, each multiemployer plan, as defined in Section 3(37) of

to the Knowledge of the Company, threatened, challenging the validity of or

     carried by the Company or any of its Subsidiaries.

               (ii) With respect to each such insurance policy: (A) the
     consummation of the Acquisition will not cause a default or require any
     consent under any such policy; (B) to the Knowledge of the Company, all
     such insurance is in full force and effect, and the Company and the
     Companies' Subsidiaries are in compliance 
 
                                       26
<PAGE>
 
     with all requirements and provisions thereof. The Company has not suffered
     any adverse loss experience which could reasonably be expected to cause its
     insurance coverage not to be renewed upon the expiration thereof at
     premiums substantially equivalent to those currently being paid or
     otherwise at commercially reasonable rates.

          (w) Warranty.  All services previously rendered by the Company and
each of its Subsidiaries have been in material conformity with all applicable
contractual commitments and all express and implied warranties, and the Company
and each of its Subsidiaries has no Liability (and the Company has no Knowledge
of any Basis for any present or future action, suit, proceeding, hearing,
investigation, charge, complaint, claim, or demand giving rise to any Liability)
for damages in connection therewith, subject only to the reserve for customer
claims set forth on the face of the Latest Financials as adjusted for the
passage of time through the Merger Date in accordance with the past custom and
practice of the Company and its Subsidiaries.  No services provided by the
Company or any of its Subsidiaries are subject to any contractual guaranty,
warranty, or other indemnity beyond the Company's or any of its Subsidiaries'
applicable standard terms and conditions of engagement.  Neither the Company nor
any of its Subsidiaries is obligated to perform services or client work for
which it will not be paid in order to correct work previously performed that was
incorrect or deficient, complete work in excess of the fixed rate limit with
respect to a particular project or otherwise, other than reasonable and
customary efforts to maintain client satisfaction consistent with the size and
scope of a particular project and consistent with maintaining the reasonable
profitability of such project.

          (x) Transaction-Related Accounting Matters.  Neither the Company nor
any of its Subsidiaries has taken or agreed to take any action that it knows or
has been advised would prevent the transactions contemplated hereby from being
accounted for as a pooling of interests in accordance with GAAP.

          (y) Brokers' Fees.  None of the Company or the Company Managers has
any Liability or obligation to pay any fees or commissions to any broker or
finder with respect to the transactions contemplated by this Agreement for which
Metzler could become liable or otherwise obligated, except for the fees and
expenses, not to exceed $3,000,000 in aggregate, of Donaldson, Lufkin & Jenrette
Securities Corporation, pursuant to its engagement Letter with the Company,
which letter has previously been delivered to Metzler.

          (z) Potential Conflicts of Interest.  Except as set forth on Schedule
3.1(z) hereof, no officer, manager, director or member of the Company or any of
its Subsidiaries:  (i) owns, directly or indirectly, any interest in (excepting
not more than 5% stock holdings for investment purposes in securities of
publicly held and traded companies) or is a shareholder, officer, director,
employee or consultant of any Person which is a competitor, lessor, lessee,
customer or supplier of the Company or any of its Subsidiaries; (ii) owns,

except for claims in the Ordinary Course of Business, such as for accrued
salary, bonus, vacation pay and benefits under Benefit Plans and similar matters
and agreements existing on the date hereof; (iv) has made, on behalf of the
Company or any of its Subsidiaries, any payment or commitment to pay any

Person of which any officer, manager or director of the Company or any of its
Subsidiaries, or, a relative of any of the foregoing, is a partner or
shareholder (except stock holdings solely for investment purposes in securities
of publicly held and traded companies). No Affiliate of any Member has any claim
against the Company, other than for wages for services performed and related
business expenses incurred in the Ordinary Course of Business.

Company contained in this Agreement or the Disclosure Schedule contains any
untrue statement of a material fact or omits a material fact necessary to make
the statements contained herein or therein, in light of the circumstances in
which they were made, not misleading.  There is no material fact which has not
been disclosed to Metzler which results in, or could reasonably be anticipated

Acquisition Sub's assets pursuant to the terms of, any contract, agreement,
lease, sublease, license, sublicense, franchise, permit, indenture, agreement
for borrowed money, instrument of indebtedness, Security Interest or other
arrangement to which Metzler or Acquisition Sub is a party or by which it is
bound or to which any of its assets are subject, except where such violations,
conflicts, breaches, defaults or other events would not, individually or in the
aggregate, result in a Metzler Adverse Effect or prevent or materially delay the
consummation of the transactions contemplated hereby. Except pursuant to the HSR
Act, neither Metzler nor Acquisition Sub is required to give any notice to, make
any filing with, or obtain any authorization, consent, or approval of any
government, governmental agency or court, or any other Person in order for the
parties to consummate the transactions contemplated by this Agreement and in
order that the Acquisition and such transactions shall not constitute a breach

encumbrance on any of Metzler's or Acquisition Sub's assets pursuant to the
provisions of, any agreement, arrangement or understanding or any license,
franchise or permit.

          (d)  Metzler Common.  Metzler has taken all actions necessary to
authorize and approve the issuance of the Metzler Common, and as of the Merger
Date the Metzler Common will, when issued in accordance herewith, be duly
authorized, validly issued, fully paid and nonassessable.  There are no
statutory or contractual shareholders' preemptive rights or rights of refusal

     herein, there are no options, warrants, calls, rights, commitments or
     agreements of any character to which Metzler or any Subsidiary of Metzler
     is a party or by which any of them is bound obligating Metzler or any
     Subsidiary of Metzler or any securities or rights convertible into or
     exchangeable for any such capital stock.

"Metzler SEC Reports").  The Metzler SEC Reports (i) at the time filed, complied
in all material respects with the applicable requirements of the Exchange Act,
or Securities Act, as applicable, and (ii) did not at the time they were filed

then on the date of such filing) contain any untrue statement of a material fact
or omit to state a material fact required to be stated in such Metzler SEC
Reports or necessary in order to make the statements in such Metzler SEC

Knowledge of Metzler, no event has occurred which has had a Metzler Adverse
Effect and no action, suit, claim or proceeding has been filed, or threatened in
writing, which if adversely determined, would result in a Metzler Adverse
Effect.

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

     5.1.  Post-Acquisition Covenants.  The Parties agree as follows with
respect to the period following the Merger Date:

          (a)  General.  In case at any time after the Merger Date any further
action is necessary or desirable to carry out the purposes of this Agreement,
each of the Parties will take such further action (including the execution and
delivery of such further instruments and documents, and in the case of Metzler,
using its reasonable efforts to cause the listing of the shares of Metzler
Common issuable in the Acquisition on Nasdaq) as any other Party reasonably may
request, at the sole cost and expense of the requesting Party (unless the
requesting Party is entitled to indemnification with respect to such matter
under Section 5.4).

          (b)  Tax Matters.  Metzler and the Company Managers shall cooperate
fully, as and to the extent reasonably requested by the other Party, in
connection with the filing of Tax Returns of the Company and its Subsidiaries
and any audit, litigation or other proceeding with respect to any Taxes of the
Company or any of its Subsidiaries or any Taxes incurred in connection with any
of the transactions contemplated by this Agreement.

          (c)  Indemnification of Managers and Officers.  The Surviving Entity
shall indemnify, defend, hold harmless and advance expenses to the individuals
who are the Company Managers and officers of the Company as of the date of this
Agreement to the same extent, if any, that such Managers and officers are
indemnified under the terms of the Operating Agreement or otherwise in respect
of any claims brought after the date of this Agreement relating to events
occurring on or prior to the date of this Agreement. In the event the Surviving
Entity or its successors or assigns (i) consolidates with or merges into any
other Person and shall not be the continuing or surviving corporation or entity
in such consolidation or merger or (ii) transfers all or substantially all its
properties and assets to any Person, then, and in each case, proper provision
shall be made so that the successors and assigns of the Surviving Entity, as the
case may be, honor the indemnification obligations set forth in this Section (it
being understood that the amount of such indemnification and expenses shall
constitute Metzler Indemnifiable Losses to the extent they relate to a breach of
a representation or warranty by the Company).

                                6.  TERMINATION
                                    -----------

     6.1.  Termination.  This Agreement may be terminated at any time prior to
the Effective Date (by written notice by the terminating party to the other
party) only as follows:

          (a)  Consent.  By mutual written consent of Metzler and the Company;
or
          
                                       37
<PAGE>
 
          (b)  Failure to Close.  By either Metzler or the Company if the
Closing shall not have occurred by September 1, 1998 (provided, however, that
the right to terminate this Agreement under this Section 6.1(b) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement has been the cause of or resulted in the failure of the Merger to
occur on or before such date); or

          (c)  Breach.  By either party if a breach of any representation or
warranty on the part of the other party set forth in this Agreement was
inaccurate or untrue as of the time made or re-made, other than an inaccuracy or
untruth which would not, individually or in the aggregate, result in a Material
Adverse Effect on the breaching party; or

          (d)  Intentionally Omitted.

     6.2.  Effect of Termination.  In the event of termination of this Agreement
pursuant to Section 6.1, there shall be no Liability or obligation on the part
of Metzler, the Company, or their respective officers, directors, managers,
stockholders, Members or Affiliates, except to the extent that such termination
results from the willful breach by a party of any of its representations,
warranties, covenants or agreements in this Agreement; and provided, that the
provisions of the confidentiality agreements contained or referred to herein
shall remain in full force and effect and survive any termination of this
Agreement.

                               7.  MISCELLANEOUS
                                   -------------

     7.1.  Press Releases and Announcements.  No Party shall issue any press
release or announcement relating to the subject matter of this Agreement without
the prior written approval of the other Party (for purposes hereof, Metzler and
the Acquisition Sub shall be deemed one party and the Company and the Members
collectively shall be deemed another Party); provided, however, that any Party
may make any public disclosure it believes in good faith is required by law or
regulation, including, without limitation, any disclosures made necessary by
Metzler's status as a public company (in which case the disclosing Party will
advise the other Party prior to making the disclosure).

     7.2.  No Third Party Beneficiaries.  Except for Section 5.1(c), this
Agreement shall not confer any rights or remedies upon any Person other than the
Parties and their respective successors and permitted assigns.

     7.3.  Entire Agreement.  This Agreement (including the other documents
referred to herein) constitutes the entire agreement between the Parties and
supersedes any prior understandings, agreements, or representations by or
between the Parties, written or oral, that may have related in any way to the
subject matter hereof.

     7.4.  Succession and Assignment.  This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign this Agreement or any of such Party's
rights, interests, or obligations

                                       38

hereunder without the prior written approval of the other Parties.
Notwithstanding the foregoing, Metzler may (i) cause the stock of the Company to
be acquired by a wholly owned subsidiary of Metzler and/or (ii) merge the
Company with or into a wholly-owned direct or indirect subsidiary of Metzler, in
either case without affecting its rights hereunder; provided that any such
actions shall not affect the tax treatment of the Acquisition.

     7.5.  Survival.  All of the representations and warranties of the Company
and the Company Managers contained in Section 3.1 hereof (the "Company
Representations"), shall survive the consummation of the Acquisition (regardless
of any Knowledge or investigation of Metzler, Acquisition Sub or the Surviving
Entity) and shall continue in full force and effect until April 30, 1999 (the
"Survival Period"). All of the representations and warranties of Metzler
contained in Section 3.2 (the "Metzler Representations") shall survive the
consummation of the Acquisition (regardless of any Knowledge or investigation of
the Members or the Company) and shall continue in full force and effect until
the expiration of the Survival Period. All covenants (as opposed to
representations and warranties) of the Parties in this Agreement shall survive
the consummation of the Acquisition and shall continue in full force
notwithstanding the expiration of the Survival Period.

     7.6.  Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

     7.7.  Notices.  All notices, requests, demands, claims, and other
communications hereunder will be in writing. Any notice, request, demand, claim,
or other communication hereunder shall be deemed duly given (i) three (3)

Any Party may give any notice, request, demand, claim, or other communication
hereunder using any other means (including personal delivery, expedited courier,
messenger service, telecopy, telex, ordinary mail, or electronic mail), but no
such notice, request, demand, claim, or other communication shall be deemed to

for whom it is intended. Any Party may change the address to which notices,
requests, demands, claims, and other communications hereunder are to be
delivered by giving the other Parties notice in the manner herein set forth.

     7.8.  Governing Law.  This Agreement shall be governed by and construed in
accordance with the domestic laws of the State of Illinois, without giving
effect to any choice of law or conflict of law provision or rule (whether of the
State of Illinois, any other jurisdiction) that would cause the application of
the laws of any jurisdiction other than the State of Illinois. Each party hereto
(a) agrees that any suit, action or other legal proceeding relating hereto may
be brought in state court sitting in the County of Cook, Illinois or the United
States District Court for the Northern District of Illinois, as applicable; and
(b) consents to the jurisdiction of each such court in any such suit, action or
proceeding; and (c) waives any objection said party may have to the laying of
venue in any such suit, action or proceeding in either such court; and (d)
consents to service of process by U.S. mail.

     7.9.  Amendments and Waivers.  No amendment of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by
Metzler, the Company and the Members. No waiver by any Party of any default,
misrepresentation or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation or breach of warranty or covenant hereunder or affect
in any way any rights arising by virtue of any prior or subsequent occurrence of
such kind.

<PAGE>
 
     7.10.  Severability.  Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the invalid or unenforceable term or provision
in any other situation or in any other jurisdiction. If a final judgment of a
court of competent jurisdiction declares that any term or provision hereof is
invalid or unenforceable, the Parties agree that the court making the
determination of invalidity or unenforceability shall have the power to reduce
the scope, duration, or area of the term or provision, to delete specific words
or phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, and
this Agreement shall be enforceable as so modified after the expiration of the
time within which the judgment may be appealed.

     7.11.  Expenses.  Each of Metzler and the Company will bear its own direct
and indirect costs and expenses (including fees and expenses of legal counsel,
investment bankers, brokers, accountants or other representatives or
consultants) incurred in connection with the negotiation, preparation and
execution of this Agreement and the consummation of the transactions
contemplated hereby, whether or not such transactions are consummated. If the
Acquisition is consummated, then expenses paid or accrued by the Company to
effect the Acquisition shall be paid by the Company, except that Metzler shall
pay such fees and expenses of each of (i) Donaldson, Lufkin and Jenrette
Securities Corporation (not to exceed $3,000,000); (ii) $25,000 of the fees and
expenses of Sidley & Austin; and (iii) the Company's independent auditors
incurred in connection with the Company's participation in the Acquisition,
which costs and expenses shall in no event include costs and expenses incurred
in connection with the personal accounting and tax planning of individual
Members.

     7.12.  Construction.  The Parties have jointly participated in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumptions or burdens of proof
shall arise favoring any Party by virtue of the authorship of any of the
provisions of this Agreement. Any reference to any Federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
Parties intend that each representation, warranty and covenant contained herein
shall have independent significance. If any Party has breached any
representation, warranty or covenant contained herein in any respect, the fact
that there exists another representation, warranty or covenant relating to the
same subject matter (regardless of the relative levels of specificity) which the
Party has not breached shall not detract from or mitigate the fact that the
Party is in breach of the first representation, warranty, or covenant.

     7.13.  Incorporation of Exhibits and Schedules.  The Exhibits and Schedules
identified in this Agreement are incorporated herein by reference and made a
part hereof.

     7.14.  Directly or Indirectly.  Where any provision in this Agreement
refers to action to be taken by any Person, or which such Person is prohibited
