Accounts Payable Report (collectively, the "Effective Date Financial Reports")
shall be prepared by the Buyer and the Buyer's Accountants as promptly as
possible after the Closing, and the Buyer shall deliver the Effective Date
Reports to the Seller and the Company's Accountants as soon as possible but in

shall review the Effective Date Financial Reports (including any corresponding
work papers of Buyer's Accountants) and report to the Buyer's Accountants in
writing within 15 days of receipt thereof of any discrepancy.  If  the Company's
Accountants and the Buyer's Accountants cannot resolve such discrepancy within
15 days after Buyer's Accountants receipt of such report, then they shall so
notify the Sellers and the Buyer, and the Sellers and the Buyer shall attempt to
resolve the discrepancy within 15 days of such notice.  If the Sellers and the
Buyer cannot resolve the discrepancy to their mutual satisfaction, another
independent public accounting firm acceptable to the Sellers and the Buyer shall
be retained to review the Effective Date Financial Reports.  The final net worth
of the Company ("Final Net Worth") shall be determined consistent with the
methods used by the Buyer's Accountants in preparing the Company's June 30, 1997
Balance Sheet Reports (e.g., the CitiBank Debt shall be deemed to remain
outstanding and commissions and taxes payable shall be accrued). Such firm's
conclusions as to the carrying values to appear on the Effective Date Financial
Reports for purposes of determining the Final Net Worth shall be conclusive.
The Sellers and the Buyer shall share equally in the expenses of retaining such
independent accounting firm.  The Buyer shall pay the expenses of the Buyer's
Accountants for their review of the Effective Date Financial Reports, and the
Sellers shall pay the expenses of Company's Accountants for their review of the
Effective Date Financial Reports.

     F.   POST-CLOSING ADJUSTMENT OF PURCHASE PRICE.  Subject to the last
sentence of this paragraph, after the Closing Date, the Purchase Price set forth
in Section 2(B) shall be adjusted as follows: (i) if the Final Net Worth of the
Company as finally determined pursuant to Section 2(E) shall be more than the
Guaranteed Net Worth, then the Cash Payment shall be increased by the amount of
such excess and (ii) if the Final Net Worth of the Company as finally determined
pursuant to Section 2(E) shall be less than the Guaranteed Net Worth, then the
Cash Payment shall be decreased by the amount of such shortfall.  In the event
that the Final Net Worth is more than the Guaranteed Net Worth, the Buyer shall
within 15 days pay such amount of cash to the Sellers.  In the event that the
Final Net Worth is less than the Guaranteed Net Worth, the Sellers shall within
15 days refund such amount of cash to Buyer. Notwithstanding the foregoing, any
downward adjustment proposed to be made to the Final Net Worth arising from
facts that should have been, but were not, reflected in the Company Financial
Statements shall be subject to and shall count against the Threshold Amount set
forth in Section 7B(iv) hereof.

represents and warrants to the Buyer that the statements contained in this (S) 4
are correct and complete as of the date of this Agreement, except as set forth
in Sellers' disclosure schedule attached hereto as Schedule 4A ("Sellers'
                                                   -----------           
Disclosure Schedule").  Nothing in the Sellers' Disclosure Schedule shall be
deemed adequate to disclose an exception to a representation or warranty made
herein, however, unless the Sellers' Disclosure Schedule identifies the
exception with reasonable particularity and describes the relevant facts in
reasonable detail.

          (A)  ORGANIZATION, QUALIFICATION, AND CORPORATE POWER.  The Company is
     a corporation duly organized, validly existing, and in good standing under
     the laws of California.  The Company is not qualified to do business in any
     other jurisdiction, nor 

                                      -11-
<PAGE>
 
     does the nature of its business require such qualification. The Company has
     full corporate power and authority and all material licenses, permits, and
     authorizations necessary to carry on the businesses in which it is engaged
     and to own and use the properties owned and used by it. (S) 4A(a) of the
     Sellers' Disclosure Schedule lists the directors and officers of the
     Company. The Sellers have delivered to the Buyer correct and complete
     copies of the articles of incorporation and bylaws of the Company and its
     Subsidiaries, if any (as amended to date), as well as the minute book
     (containing the records of meetings of the stockholders, the board of
     directors, and any committees of the board of directors), the stock
     certificate book, and the stock record book of the Company (all of which
     are correct and complete in all material respects). The Company is not in
     default under or in violation of any provision of its articles of
     incorporation or bylaws.

          (B)  CAPITALIZATION.  The entire authorized capital stock, the issued
     and outstanding shares and the treasury shares of the Company are
     accurately set forth in (S) 4A(b) of the Sellers' Disclosure Schedule.  All
     of the issued and outstanding Subject Shares have been duly authorized, are
     validly issued, fully paid, and nonassessable, and are held of record by
     the Sellers as set forth in (S) 4A(b) of the Sellers' Disclosure Schedule.
     There are no outstanding or authorized options, warrants, purchase rights,
     subscription rights, conversion rights, exchange rights, or other contracts
     or commitments that would require the Company to issue, sell, or otherwise
     cause to become outstanding any of its capital stock. There are no
     outstanding or authorized stock appreciation, phantom stock, profit
     participation, or similar rights with respect to the Company.  There are no
     voting trusts, proxies, or other agreements or understandings with respect
     to the voting of the capital stock of the Company.

          (C)  NONCONTRAVENTION.  Neither the execution and the delivery of this
     Agreement, nor the consummation of the transactions contemplated hereby,
     will (i) violate any constitution, statute, regulation, rule, injunction,
     judgment, order, decree, ruling, charge, or other restriction of any
     government, governmental agency, or court to which the Company is subject,
     (ii) violate any provision of the articles of incorporation or bylaws of
     the Company, or (iii) conflict with, result in a breach of, constitute a
     default under, result in the acceleration of, create in any party the right
     to accelerate, terminate, modify, or cancel, or require any notice under
     any agreement, contract, lease, license, instrument, or other arrangement
     to which the Company is a party or by which it is bound or to which any of
     its assets is subject (or result in the imposition of any Security Interest
     upon any of its assets).  The Company does not need to give any notice to,
     make any filing with, or obtain any authorization, consent, or approval of
     any government or governmental agency in order for the Parties to
     consummate the transactions contemplated by this Agreement.

          (D)  SUBSIDIARIES.  The Company does not have any ownership interest
     in any Subsidiaries.  The Company does not control, directly or indirectly,
     or have any direct 

                                      -12-

     governmental agency in order for the Parties to consummate the transactions
     contemplated by this Agreement.

     future action, suit, proceeding, hearing, investigation, charge, complaint,
     claim, or demand against it giving rise to any Liability), except for (i)

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) as any other Party reasonably may
request all at the sole cost and expense of the requesting Party (unless the

      B.  CONFIDENTIALITY.  The Sellers will treat and hold as such all of the
Confidential Information and refrain from using any of the Confidential

requested or required (by oral question or request for information or documents
in any legal proceeding, interrogatory, subpoena, civil investigative demand, or
similar process) to disclose any Confidential Information, Sellers will notify
the Buyer promptly of the request or requirement so that the Buyer may seek an
appropriate protective order or waive compliance with the provisions of this (S)
5B.  If, in the absence of a protective order or the receipt of a waiver
hereunder, Sellers are, on the advice of counsel, compelled to disclose any
Confidential Information to any tribunal or else stand liable for contempt,
Sellers may disclose the Confidential Information to the tribunal; PROVIDED,
HOWEVER, that Sellers shall use their reasonable best efforts to obtain, at the
reasonable request of the Buyer, an order or other assurance that confidential

by the Buyer.  The foregoing provisions shall not apply to any Confidential
Information which is generally available to the public immediately prior to the

to this Agreement or any other agreement delivered pursuant to this Agreement or
in any schedule, certificate, exhibit, or other instrument furnished or to be
furnished by the Sellers or their Affiliates pursuant to the terms of this

demonstrates that the amount the indemnified Party is entitled to recover
exceeds the actual damages to the indemnifying Party caused by such failure to
so notify within ten (10) days; provided further that a Notice of Action must be
sent to the indemnifying Party within the applicable survival period as provided
in Section 7(a) of this Agreement.  The indemnifying Party may elect to
compromise or defend any such asserted liability and to assume all obligations
contained in this (S) 7(b) to indemnify the indemnified Party by a delivery of
notice of such election ("Notice of Election") within ten (10) days after
delivery of the Notice of Action.  Upon delivery of the Notice of Election, the
indemnifying Party shall be entitled to take control of the defense and
investigation of such lawsuit or action and to employ and engage attorneys of
its own choice to handle and 

                                     -28-
<PAGE>
 
defend the same, at the indemnifying Party's sole cost, risk and expense, and
such indemnified Party shall cooperate in all reasonable respects, at the
indemnifying Party's sole cost, risk and expense, with the indemnifying Party
and such attorneys in the investigation, trial, and defense of such lawsuit or
action and any appeal arising therefrom; provided, however, that the indemnified
Party may, at its own cost, risk and expense, participate in such investigation,
trial and defense of such lawsuit or action and any appeal arising therefrom. If
the Notice of Election is delivered to the indemnified Party, the indemnified
Party shall not pay, settle or compromise such claim without the indemnifying
Party's consent, which consent shall not be unreasonably withheld. If the
indemnifying Party elects not to defend the claim of the indemnified Party or
does not deliver to the indemnified Party a Notice of Election within ten (10)
days after delivery of the Notice of Action, the indemnified Party may, but
shall not be obligated to, defend, compromise or settle (exercising reasonable
business judgment) the claim or other matter on behalf, for the account, and at
the risk, of the indemnifying Party.

          (IV)   LIMITATION ON INDEMNIFICATION. Notwithstanding any provision of
this Agreement, neither the Buyer nor the Sellers or any Affiliate of either
shall be required to pay an indemnified Party or any Affiliate thereof any
amount with respect to any claim for Damages under this (S) 7(B) until the
Damages which the indemnified Party and its Affiliates suffered under this
Agreement aggregate at least $25,000 (the "Threshold"), at which time and in
such event the indemnified Party or Affiliate shall be entitled to receive
payment for the entire amount of aggregate Damages to the extent they exceed
$25,000. No Party shall be liable to indemnify the other Parties in an aggregate
amount in excess of $1,350,000 including any and all amounts due and owing under
(S) 8(B) of this Agreement.

     8.   REMEDIES.

     A.   SPECIFIC PERFORMANCE.  Each of the Parties hereby agrees that the
transactions contemplated by this Agreement are unique, and that each Party
shall have, in addition to any other legal or equitable remedy available to it,
the right to enforce this Agreement by decree of specific performance.  If any
legal action or other proceeding is brought for the enforcement of this
Agreement, or because of an alleged dispute, breach, default or
misrepresentation in connection with any of the provisions of this Agreement,
the successful or prevailing Party or Parties shall be entitled to recover
reasonable attorneys' fees and other costs incurred in that action or proceeding
in addition to any other remedies to which it, he or they may be entitled at law
or equity.  The rights and remedies granted herein are cumulative and not
exclusive of any other right or remedy granted herein or provided by law.

     B.   OFFSET.  Any and all Damages incurred by the Buyer which permit the
Buyer to make an indemnification claim against the Sellers and to the extent not
otherwise prohibited by applicable law, shall be subject to mandatory offset by
the Buyer against all amounts due and owing by the Buyer to the Sellers under
this Agreement or any document, instrument, or agreement executed in connection
herewith.  The foregoing shall constitute the sole remedy of Buyer against
Sellers in connection with breaches of the representations, warranties,
covenants 

                                     -29-
<PAGE>
 
and obligations of the Sellers contained in this Agreement except to the extent
of any remaining unpaid claims to the extent permitted under (S) 7 of this
Agreement if there are not any Parent Shares remaining pledged to offset against
in which event Buyer may proceed against the Sellers but only for any amounts
not offset and not exceeding $1,350,000, including the amounts recovered against
the pledged Parent Shares. In the event of an offset of any Damages incurred as
a result of any such breach, the Buyer shall furnish the Sellers notice
containing detailed information about the breach, the magnitude of the Damages
that the Buyer has or reasonably expects to incur (the act of offsetting by the
Buyer shall be referred to as an "Offset"). Offsets shall first be against the
Parent Shares. For purposes hereof, the Parent Shares shall be deemed to have a
value equivalent to $8.50 per share; provided, however, that if Parent has
successfully consummated a public offering of the Parent Shares ("Public
Offering"), then the value of the Parent Shares shall be deemed to be the
average public trading price of each Parent Share over the five (5) most recent
business days falling prior to the date of delivery by the Buyer to the Sellers
of the notice of an event requiring an Offset. In order to secure the Buyer's
Offset rights against the Parent Shares, the Buyer and the Sellers shall execute
the Pledge Agreement. The Parent Shares subject to the lien created by the
Pledge Agreement shall have a restrictive legend typed on the back thereof
specifying that the Parent Shares are subject to a right of Offset as specified
in this Agreement. The Sellers acknowledge and agree that but for the right of
Offset contained in this Agreement, the Buyer would not have entered into this
Agreement or any of the transactions contemplated herein. If any legal action or
other proceeding is brought for the enforcement of this Agreement, or any
document, instrument, or agreement executed in connection herewith, or because
of an alleged dispute, breach, default or misrepresentation in connection with
any of the provisions of this Agreement or any document, instrument, or
agreement executed in connection herewith, the successful or prevailing Party
shall be entitled to recover reasonable attorneys' fees and other costs incurred
in that action or proceeding.

     9.   MISCELLANEOUS.

     A.   PUBLIC ANNOUNCEMENTS.  No Party shall issue any press release or make
any public announcement relating to the subject matter of this Agreement
(including the documents referred to herein) without the prior written approval
of the Parent, the Buyer and the Sellers; provided, however, that any Party may
make any public disclosure it believes in good faith upon the advise of legal
counsel it is required by applicable law (in which case the disclosing Party
will use its best efforts to advise the other Party prior to making the
disclosure).

     B.   NO THIRD-PARTY BENEFICIARIES.  This Agreement shall not confer any
rights or remedies upon any Person other than the Parties, the Buyer Indemnified
Parties and their respective successors and permitted assigns.

     C.   ENTIRE AGREEMENT.  This Agreement (including the documents referred to
herein) constitutes the entire agreement among the Parties and supersedes any
prior understandings, agreements, or representations by or among the Parties,
written or oral, to the extent they related in any way to the subject matter
hereof.

     D.   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 either this Agreement or any of his
or its rights, interests, or obligations hereunder without the prior written
approval of the Buyer and the Sellers; provided, however, that the Buyer may (i)
assign any or all of its rights and interests hereunder (x) to one or more of
its Affiliates, and (y) to one or more financial institutions lending funds to
the Buyer for the purpose of financing the purchase of the Subject Shares
hereunder and (ii) designate one or more of its Affiliates to perform its
obligations hereunder (in any or all of which cases the Buyer nonetheless shall
remain responsible for the performance of all of its obligations hereunder).

     E.   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.

hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,
telecopy, telex, ordinary mail, or electronic mail), but no such notice,

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.

     H.   GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF CALIFORNIA WITHOUT GIVING
EFFECT TO ANY CHOICE OR CONFLICT OF LAW PROVISION OR RULE (WHETHER OF THE STATE
OF CALIFORNIA OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE
LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF CALIFORNIA.

     I.   AMENDMENTS AND WAIVERS.  No amendments of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by the
Buyer, the Parent and the Sellers.  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 such
occurrence.

     J.   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 offending term or provision in any other
situation or in any other jurisdiction.

     K.   EXPENSES.  Each of the Parties and the Company will bear his or its

     L.   CONSTRUCTION.  The Parties have participated jointly in the

arise favoring or disfavoring 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 

                                     -32-
<PAGE>
 
or law shall be deemed also to refer to all rules and regulations promulgated
thereunder, unless the context requires otherwise. The word "including" shall
mean including without limitation. 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.

     M.   INCORPORATION OF EXHIBITS AND SCHEDULES.  The Exhibits and Schedules
identified in this Agreement are incorporated herein by reference and made a
part hereof.

     N.   ARBITRATION.  If a dispute arises out of or relates to this Agreement,
or the breach thereof, and if said dispute cannot be settled through
negotiation, the Parties agree first to try in good faith to settle the dispute
by mediation under the Commercial Mediation Rules of the American Arbitration
Association, before resorting to arbitration, litigation, or some other dispute
resolution procedure as required by this (S) 9(N).  Failing an adequate
resolution by mediation, any controversy or claim arising out of or relating to
this Agreement or the transactions contemplated hereby, including any
controversy or claim arising out of or relating to the Parties' decision to
enter into this Agreement, shall be settled by binding arbitration. There shall
be one arbitrator to be mutually agreed upon by the Parties involved in the
controversy and to be selected from the National Panel of Commercial Arbitrators
(or successor panel, if any).  If within 45 days after service of the demand for
arbitration the Parties are unable to agree upon such an arbitrator who is
willing to serve, then an arbitrator shall be appointed by the American
Arbitration Association in accordance with its rules.  Except as specifically
provided in this (S) 9(N), the arbitration shall be conducted in accordance with
the Commercial Arbitration Rules of the American Arbitration Association.  The
arbitrator shall not render an award of punitive damages.  Any arbitration
hereunder shall be held in Orange County, California.  Expenses related to the
arbitration, including counsel fees, shall be borne by the Party incurring such
expenses except to the extent otherwise provided herein.  The fees of the
arbitrator and of the American Arbitration Association, if any, shall be divided
equally among the Parties involved in the controversy.  Judgment upon the award
rendered by the arbitrator (which may, if deemed appropriate by the arbitrator,
include equitable or mandatory relief with respect to performance of obligations
hereunder) may be entered in any court of competent jurisdiction.  The
arbitrator shall award the prevailing Party in any arbitration proceeding
recovery of its attorneys' fees and other costs in connection with the
arbitration from the non-prevailing Party.

EXHIBIT A

                              EMPLOYMENT AGREEMENT
                              --------------------

     THIS EMPLOYMENT AGREEMENT (this "Agreement"), dated effective the 17th day
of September, 1997 (the "Effective Date"), is entered into by and between BURTON
HOUSE, INC., a California corporation doing business as ZISKIND, GREENE,
WATANABE & NASON (hereinafter called the "Company," which term includes any
directly or indirectly controlled subsidiaries or successor entities), and GREGG
M. ZISKIND, an individual residing in the State of California (the "Employee").
The Company and Employee may sometimes hereinafter be referred to singularly as
a "Party" or collectively as the "Parties."  All capitalized terms not otherwise
defined herein shall have the same meaning as contained in that certain Stock
Purchase Agreement executed as of September 17, 1997 (the "Purchase Agreement"),
by and among Employee, Litigation Resources of America-California, Inc., a
California corporation and the parent company of the Company ("LRA-CA"), and
Litigation Resources of America, Inc., a Texas corporation and the parent
company of LRA-CA ("LRA").

                              W I T N E S S E T H:
                              - - - - - - - - - - 

     WHEREAS, Employee has been a shareholder, director, officer, and employee
of the Company, and his knowledge of the affairs of the business, particularly
the legal recruiting and placement business in California, are of great value to
the Company; and

     WHEREAS, pursuant to the terms of the Purchase Agreement, LRA-CA has
purchased from the Employee, and the Employee has sold to LRA-CA, all the issued
and outstanding common stock of the Company; and

     WHEREAS, part of the consideration given to the Employee under the Purchase
Agreement included an agreement by LRA-CA that the Company would enter into this
Agreement; and

     WHEREAS, a condition precedent to the closing of the Purchase Agreement was
the execution of this Agreement;

     NOW THEREFORE, for and in consideration of the mutual covenants, promises
and undertakings herein contained and other consideration, the receipt and
sufficiency of which are hereby acknowledged, the Parties hereby undertake and
agree as follows:

     1.   Employment Term.  The Company hereby employs the Employee commencing
on the Effective Date for a term of three (3) years (the "Employment Term"),
unless sooner terminated as hereinafter provided.  The term of this Agreement
may be renewed or extended for one or more successive additional one (1) year
terms upon mutual agreement of the Parties at least 90 days prior to the
expiration of the initial term or any such renewal term.  Unless otherwise
provided herein, Sections 12, 13, 14, 16, 17, 22, 24 and 25 of this Agreement
shall survive the expiration or termination of this Agreement, for any reason
whatsoever.  The Employee accepts such employment 
<PAGE>
 
and agrees to perform the services specified herein, all upon the terms and
conditions hereinafter stated.

     2.   Duties.  The Employee shall serve as the President of the Company and
shall report to, and be subject to the general direction and control of the
Chief Executive Officer and the Board of Directors of the Company (the "Board").
The Employee shall perform such management and administrative duties, consistent
with the Employee's position and his position with the Company prior to the date
hereto, as are from time to time reasonably assigned to the Employee by the
Chief Executive Officer and the Board.  The Employee also agrees to perform,
without additional compensation, such other services for the Company, and for
any parent, subsidiary or affiliate corporations of the Company and any
partnerships in which the Company may from time to time have an interest (herein
collectively called "Affiliates"), as the Chief Executive Officer or Board shall
from time to time specify, if such services are of the nature commonly
associated with the position of president of a company engaged in activities
similar to the legal recruitment and placement activities engaged in by the
Company and to perform such other activities as are consistent with the
Employee's past responsibilities as an employee of the Company; provided, that
Employee shall not be required to engage in any business that is not reasonably
related to the Business of the Company, as hereinafter defined.  For purposes of
this Agreement, the "Business of the Company" or, alternatively,  "Business"
shall be defined as the current business of the Company, including, but not
limited to, the marketing and providing of legal recruiting and placement
services  in the California counties of Los Angeles and Orange.  The term
"Company" as used in this Agreement shall be deemed to include and refer to all
such Affiliates.

     3.   Extent of Service.  Except for the provision of a limited amount of
services (which shall not exceed 10% of his business time on a monthly basis) to
Legal Recruitment Network, Inc., d/b/a Employer Net ("LRN"), an "on-line"
placement service currently partially owned by the Employee, the Employee shall
devote his full business time, attention and energy to the business of the
Company, and shall not be engaged in any other business activity during the term
of this Agreement.  The foregoing shall not be construed as preventing the
Employee from making passive investments in other businesses or enterprises, if
(i) such investments will not require services on the part of the Employee which
would in any material way impair the performance of his duties under this
Agreement, (ii) such other businesses or enterprises (other than LRN) are not
engaged in any business competitive with the business of the Company, and (iii)
the Employee has complied with Sections 12 and 13 of this Agreement with respect
to each such passive investment.

     4.   Compensation.  As payment for the services to be rendered by the
Employee hereunder during the initial term, the Employee shall be entitled to
receive:

     (a) a salary in the aggregate amount of One Hundred Thousand Dollars
  ($100,000.00) per year effective as of the date hereof, which shall be payable
  monthly or in accordance with the payroll policies of the Company in effect
  from time to time if such policies provide for payment of salary more
  frequently than monthly, until the date of termination of Employee's
  employment under this Agreement;

                                      -2-
<PAGE>
 
          (b)  commissions based upon the revenues generated from National
  Account (as defined below) sales originated by the Employee.  The amount of
  commissions payable will be based upon a formula ("Formula") to be established
  by the Board of Directors of LRA.  The Formula may be amended from time to
  time by LRA's Board of Directors and the Employee shall be entitled to receive
  compensation hereunder based upon the Formula as it exists on the date of the
  origination of the National Account.  A "National Account" is any account
  established with an insurance or "Fortune 500" company pursuant to which two
  or more of LRA's offices in different geographical areas render services.
  Until notice of a change in the Formula applicable to the Employee is given to
  the Employee by LRA's Board of Directors, the Formula applicable to the
  Employee shall be as follows:
 
Commission                         Price Structure of
Percentage of Gross Sales          National Account

                                   market price rate
                                 
  1.50%                            Discount of 15% to less than 20% from
                                   market price rate
                                 
  1.00%                            Discount of 20% to less than 25% from
                                   market price rate
                                 
  0.50%                            Discount of 25% or more from market price
                                   rate

     In certain circumstances, more than one individual may be entitled to
  receive commissions based upon sales from a National Account.  In such
  circumstances, the commissions described above would be shares by the Employee
  and the other individual(s) on such a basis as is determined to be fair by
  LRA's Board of Directors. All commissions payable hereunder will be paid in
  cash within 45 days of the end of the calendar year in which they are earned.

     (c) in the event that the Employee provides assistance to LRA in connection
  with LRA's acquisition of an acquisition candidate, the Employee shall be
  entitled to receive, at the closing of such acquisition, a cash payment equal
  to 10% of any finder's fees or commissions payable to any third party by LRA
  or its subsidiary in connection with such acquisition.  The Employee shall
  identify potential acquisition candidates by giving written notice to LRA's
  management ("Acquisition Notice") prior to expending any efforts to effect any
  such acquisition and shall only be entitled to compensation hereunder in the
  event that 

                                      -3-
<PAGE>
 
  LRA authorizes the Employee to actively pursue such acquisition. In no event
  shall LRA or any subsidiary be obligated to close any acquisition with regard
  to any business identified by the Employee as an acquisition candidate, and no
  fee shall be payable hereunder unless and until such acquisition closes. In
  the event another individual employed by LRA or its subsidiaries claims a
  commission on any acquisition candidate identified in an Acquisition Notice
  (which commission (if paid) would be duplicative of any commission paid to the
  Employee hereunder), the Company agrees to negotiate in good faith with the
  Employee regarding a fair and reasonable allocation of such commission between
  the Employee and such other individual.

     (d) with regard the following placements: Kelley/Schwartz;
  Richards/Thorson; Bronson/Langberg; Ginsberb/Theodora; Arter/Hill; and
  Kaye/Pilmer, the Company shall pay the Employee in accordance with its usual
  practice a commission equal to any additional amounts collected (net of other
  commissions payable out of such amount) in excess of the accounts receivable
  reflected on the books of the Company on the date hereof with regard to each
  such placement.

     5.   Expenses.  During the term of this Agreement, the Company shall
promptly pay or reimburse the Employee for all reasonable out-of-pocket expenses
for travel, meals, hotel accommodations and similar items incurred by him in
connection with the Business of the Company and approved by the Board or
incurred in accordance with the travel and reimbursement policies of the Company
as the same shall be in effect from time to time, upon submission by him of an
appropriate statement documenting such expenses. The Company and the Employee
have budgeted $800.00 per month for promotional and entertainment expenses of
the Employee expected to be incurred by the Employee in the conduct of his
duties hereunder.  The Company agrees to reimburse the Employee for all such
expenses subject to the documentation requirements set forth above. The Company
shall also pay the Employee a non-accountable automobile allowance in the amount
of $600.00 per month.

     6.   Employee Benefits.  During the term of this Agreement, the Employee
shall be entitled to participate in all employee benefit plans from time to time
made generally available to the executive employees of the Company, including
any stock option plan, retirement plan, profit-sharing plan, group life plan,
health or accident insurance or other employee benefit plans as the same shall
be maintained in effect, as determined by the Board.

     7.   Vacation.  During the term of this Agreement, the Employee shall be
entitled to annual vacation time determined in accordance with the vacation
policies of the Company in effect from time to time but not less than four (4)
weeks per year, during which time his compensation shall be paid in full.
Unused vacation time shall not accrue from year to year.

     8.   Covenants of Employee.  For and in consideration of the employment
herein contemplated and the consideration paid or promised to be paid by the
Company, the Employee does hereby covenant, agree and promise that during the
term hereof and thereafter to the extent specifically provided in this
Agreement:

                                      -4-
<PAGE>
 
     (a) The Employee will use his best reasonable efforts to truthfully and
  accurately make, maintain and preserve all records and reports that the
  Company may from time to time request or require.

     (b) The Employee will fully account for all money, records, goods, wares
  and merchandise or other property belonging to the Company of which the
  Employee has custody, and will pay over and deliver same promptly whenever and
  however he  may be reasonably directed to do so by the Company.

     (c) The Employee will obey all rules, regulations and special instructions
  of the Company applicable to him, and will be loyal and faithful to the
  Company at all times.

     (d) Upon request, the Employee will make available to the Company any and
  all of the information of which he has knowledge relating to the business of
  the Company.

     (e) The Employee agrees that upon termination of his employment hereunder
  he will immediately surrender and turn over to the Company all books, records,
  forms, specifications, formulae, data, processes, papers and writings related
  to the Business of the Company and all other property belonging to the
  Company, together with all copies of the foregoing, it being understood and
  agreed that the same are the sole property of the Company.

     (f) The Employee agrees that all ideas, concepts, processes, discoveries,
  devices, machines, tools, materials, designs, improvements, inventions and
  other things of value relating to the Business of the Company (hereinafter
  collectively referred to as "intangible rights"), whether patentable or not,
  which are conceived, made, invented or suggested by him alone or in
  collaboration with others during the term of his employment, and whether or
  not during regular working hours, shall be promptly disclosed in writing to
  the Company and shall be the sole and exclusive property of the Company.  The
  Employee hereby assigns all of his right, title and interest in and to all
  such intangible rights to the Company, and its successors or assigns.  In the
  event that any of such intangible rights shall be deemed by the Company to be
  patentable or otherwise registerable under any federal, state or foreign law,
  the Employee further agrees that, at the expense of the Company, he will
  execute all documents and do all things reasonably necessary, advisable or
  proper to obtain patents therefor or registration thereof, and to vest in the
  Company full title thereto.

     9.   Mutual Covenants of the Company and the Employee.  For and in
consideration of the employment herein contemplated and the compensation,
covenants, conditions and promises herein recited, the Company and the Employee
do hereby mutually agree that during the term hereof:

     (a) The Employee shall not, by reason of this Agreement, have any vested
  interest in, or right, title or claim to, any land, buildings, equipment,
  machinery, processes, systems, products, contracts, goods, wares, merchandise,
  business assets or other things of value belonging to or which may hereafter
  be acquired or owned by the Company.

                                      -5-
<PAGE>
 
     (b) In carrying out his duties as President of the Company, the Employee
  shall primarily be responsible for making day-to-day decisions in the ordinary
  course of business of  the Company, subject to possible review by the Chief
  Executive Officer and/or the Board. The responsibility for the Company's
  plans, properties, contracts, methods, and policies shall be vested in the
  Board and the Company may, in its sole and absolute discretion, give, sell,
  assign, transfer or otherwise dispose of any or all of its assets or
  businesses in whole or in part, to any person, firm or corporation, whether or
  not such person, firm or corporation is in any manner owned by or associated
  with or affiliated with the Company.

     (c) The Employee acknowledges that because of the nature of the position
  for which he has been employed, the Employee may be called upon to perform
  such duties and render such services as are required of him hereunder
  irregularly, and agrees to perform to the best of his abilities such duties as
  the business may reasonably demand, and acknowledges that the number of hours
  per day or per week may vary.
 
     10.  Termination of Employment for Cause.  The Company may terminate the
employment of the Employee if the Company suffers or may reasonably be expected
to suffer any material adverse effect as a result of the Employee (any such
termination being a termination for "Cause"):

     (a)  Breaching any material provision of this Agreement and failing to cure
  such breach within ten (10) days after receipt of written notice thereof;

     (b)  Misappropriating funds or property of the Company;

     (c)  Securing any personal profit not thoroughly disclosed to and approved
  by the Company in connection with any transaction entered into on behalf of
  the Company;

     (d)  Engaging in conduct, even if not in connection with the performance of
  his duties hereunder, which would reasonably be expected to result in a
  material adverse effect to the interest of the Company if he were retained as
  an employee, such as his commission of a felony or a crime of moral turpitude;

     (e)  Becoming and remaining "Disabled," as hereinafter defined (either
  physically, mentally or otherwise) for a period of one hundred thirty-five
  (135) days during any consecutive twelve-month time period;

     (f)  Failing to carry out and perform the duties assigned to the Employee
  consistent with the terms hereof and failing to cure such breach within ten
  (10) days after written notice thereof;

     (g)   Failing to comply with consistently applied corporate policies of the
  Company that are promulgated from time to time and made known to Employee and
  failing to cure such breach within ten (10) days after written notice thereof;
  or

                                      -6-
<PAGE>
 
     (h)   dying.

     In the event the Employee is terminated for Cause because he is Disabled,
the Employee may be permitted to participate in any disability insurance policy
the Company then has in effect.

     In the event of termination of his employment for Cause, the Employee shall
be entitled to receive his compensation, as determined in Section 4 of this
Agreement, due or accrued on a pro rata basis to the date of termination.  Any
salary or remuneration owed as of the date of termination shall be paid less the
amount of damages, if any, caused to the Company by such breach, but no such
damages offset shall extend beyond any compensation due and owing under this
Agreement.

     Notwithstanding the cure provisions provided in Sections 10(a), 10 (f) and
10(g), the Employee shall not have the opportunity to cure any violation of
these subsections if such violation cannot reasonably be expected to be cured.
In such event, the Company shall be required to furnish the Employee notice of
the alleged violation, but the Employee shall not be furnished an opportunity to
cure.

     "Disabled" shall mean the continuous inability, whether mental or physical,
of Employee to perform his normal job functions as determined by at least two of
three medical physicians selected as follows:  the Employee or his legal
designee shall be entitled to appoint one physician, the Company shall be
entitled to appoint one physician, and such two appointed physicians shall
mutually appoint a third physician.  Notwithstanding the foregoing, the
Employee, or his designee, and the Company may mutually agree that he is
"Disabled" within the meaning of this Agreement.

     11.  Termination By the Company Without Cause or By the Employee With Good
Reason. The Company may terminate the employment of Employee for any reason
other than those for Cause, in which event such termination shall be deemed a
"Termination Without Cause."  In addition, the Employee shall have the right to
terminate this Agreement for any material breach of this Agreement by the
Company, which shall include but not be limited to materially changing the
duties assigned to Employee beyond those contemplated in Section 2 of this
Agreement or causing Employee to relocate his primary residence outside of the
area set forth in Section 2 of this Agreement; provided that the Company shall
be furnished ten (10) days notice of such breach and an opportunity to cure (any
such termination constituting a "Termination By Employee With Good Reason").
Notwithstanding the cure provisions provided in the preceding sentence, the
Company shall not have the opportunity to cure any violation of this Agreement
if such violation cannot reasonably be expected to be cured but the Employee
shall still furnish notice to the Company.  In the event of a Termination
Without Cause or a Termination with Good Reason by the Employee the Company
shall continue making payments to Employee in an amount equal to the
compensation of the Employee, as determined in Section 4 of this Agreement, as
if he was still employed for a period equal to the lesser of (i) one (1) year,
or (ii) the remaining term of this Agreement, which amount, in the event of a
Termination Without Cause or a Termination  By Employee With Good Reason, shall
constitute the full and total amount of liquidated damages that the Employee
shall be entitled to receive from the Company and its Affiliates for any
contractual or tort claims arising out of his employment relationship with the
Company.

     12.  Covenant Not to Compete.  The Employee recognizes that the Company has
business goodwill and other legitimate business interests which must be
protected in connection with and in addition to the Information (as defined
hereinafter), and therefore, in exchange for access to the Information, the
specialized training and instruction which the Company will provide, the
Company's agreement to employ the Employee on the terms and conditions set forth
herein, the agreement by LRA-CA to execute and consummate the Purchase
Agreement, and the promotion and advertisement by the Company of Employee's
skill, ability and value in the Company's business, subject to the provisions of
the next full paragraph of this Section 12, the Employee agrees that (a) during
the term of this Agreement, except as otherwise specifically permitted herein,
Employee will not actively engage, directly or indirectly, in any other business
other than that of Company and (b) in the event (i) Employee is terminated for
Cause, or (ii) Employee leaves the employ of the Company other than a
Termination By Employee With Good Reason prior to expiration of the term of the
Agreement, or (iii) upon the expiration of the term of this Agreement, then for
a period of four and one-half (4-1/2) years after the date of this Agreement (if
such period extends beyond the date the Employee's service hereunder is so
terminated):

     (a)   Employee will not in any capacity or relationship enter into, engage
  in, or be connected with any business or business operation or activity (i)
  within Orange and Los Angeles Counties which competes with the Business of the
  Company or (ii) which is in competition with the Business and is located
  within 50 miles of any office operated by LRA or any Affiliate of LRA which is
  also engaged in the Business; and

     (b)   Employee will not call upon any customer whose account is serviced in
  whole or in part by the Company or its Affiliates at the time of the
  termination of Employee's employment, with the purpose of selling or
  attempting to sell to any such customer any services included within that
  offered by the Company or its Affiliates engaged in the Business; and

     (c)   Employee will not intentionally divert, solicit or take away any
  customer, supplier or employee of the Company or its Affiliates engaged in the
  Business, or the patronage of any customer or supplier of the Company or its
  Affiliates engaged in the Business, or otherwise interfere with or disturb the
  relationship existing between the Company or its Affiliates and any of their
  respective customers, suppliers or employees, directly or indirectly.

     In addition, the foregoing restrictive covenants shall also apply to the
Employee in the event of his Termination Without Cause or in the event of
Termination By Employee With Good Reason by the Employee, but only for a period
of one (1) year from such date of termination.

     In the event the Company ceases operation of the Business of the Company
(other than in a merger, consolidation, sale of assets or similar transaction,
or upon the filing of a bankruptcy or receivership proceeding against the
Company, or upon the appointment of a liquidator for the Company), the
provisions of this Section 12 shall not be applicable to the conduct of Employee
subsequent thereto.

                                      -8-
<PAGE>
 
     It is mutually understood and agreed that if any of the provisions relating
to the scope, time or territory in this Section 12 are more extensive than is
enforceable under applicable laws or are broader than necessary to protect the
good will and legitimate business interests of the Company, then the Parties
agree that they will reduce the degree and extent of such provisions by whatever
minimal amount is necessary to bring such provisions within the ambit of
enforceability under applicable law.

     The Parties acknowledge that the remedies at law for breach of Employee's
covenants contained in this Section 12 are inadequate, and they agree that the
Company shall be entitled, at its election, to injunctive relief (without the
necessity of posting bond against such breach or attempted breach), and to
specific performance of such covenants in addition to any other remedies at law
or equity that may be available to the Company.

     13.  Business Opportunities.  Except for passive investments by the
Employee in publicly traded entities, or investments in private ventures which
do not compete with, or are not in the same business as, the Company and which
come to the attention of the Employee outside of the scope of his employment,
for as long as the Employee shall be employed by the Company (and thereafter
with respect to any business opportunities learned about during the time of
Employee's employment by the Company), the Employee agrees that with respect to
any future business opportunity or other new and future business proposal which
is offered to, or comes to the attention of, the Employee and which is in any
way related to, or connected with, the Business of the Company within the
aforementioned time periods, the Company shall have the right to take advantage
of such business opportunity or other business proposal for its own benefit. The
Employee agrees to promptly deliver notice to the Board in writing of the
existence of such opportunity or proposal and the Employee may take advantage of
such opportunity only if the Company does not elect to exercise its right to
take advantage of such opportunity.

     14.  Confidential Information.  The Employee acknowledges that in the
course of his employment with the Company, he will receive certain trade
secrets, know-how, lists of customers, employee records and other confidential
information and knowledge concerning the Business of the Company (hereinafter
collectively referred to as "Information") which the Company desires to protect.
The Employee understands that such Information (except for Information which is
generally known in the industry) is confidential and he agrees that he will not
reveal such Information to anyone outside the Company except (i) for information
already known to the public, now or in the future, or (ii) in connection with
any legal proceeding regarding this Agreement, the Purchase Agreement or the
transactions contemplated thereby or as otherwise required by law or judicial
order.  The Employee further agrees that during the term of this Agreement and
thereafter he will not use such Information in competing with the Company.  Upon
termination of his employment hereunder, the Employee shall surrender to the
Company all papers, documents, writings and other property produced by him or
coming into his possession by or through his employment hereunder and relating
to the information referred to in this Section 14, which are not general
knowledge in the industry, and the Employee agrees that all such materials will
at all times remain the property of the Company.

     15.  Notices.  All notices, consents, demands or other communications
required or permitted to be given pursuant to this Agreement shall be deemed
sufficiently given when delivered personally with a written receipt
acknowledging delivery or telefaxed with receipt confirmed, or three (3)
business days after the posting thereof by United States first class, registered
or certified mail, return receipt requested, with postage fee prepaid and
addressed as follows:

     Any Party may change its address for notice hereunder by providing written
notice of such change to the other Party hereto.

     16.  Specific Performance.  The Employee acknowledges that a remedy at law
for any breach or attempted breach of Sections 12, 13 or 14 of this Agreement
will be inadequate, the Employee agrees that the Company shall be entitled to
specific performance and injunctive and other equitable relief in case of any
such breach or attempted breach, and further agrees to waive any requirement for
the securing or posting of any bond in connection with the obtaining of any such
injunctive or any other equitable relief.  Without limiting the Company's right
to otherwise enforce the provisions of this Agreement through specific
performance and injunctive and other relief, the Company agrees not to seek
monetary damages from the Employee arising either (a) out of acts or omissions
by the Employee which cause damages to a third party for which damages the
Company has become liable unless such acts or omissions constituted grossly
negligent, willful or intentional acts or omissions of the Employee or (b)
solely because the Employee leaves the employ of the Company other than pursuant
to a Termination By Employee With Good Reason prior to expiration of the term of
the Agreement.

     17.  Severability.  Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provisions shall be ineffective to the extent
of such provision or invalidity only, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

     18.  Assignment.  This Agreement may not be assigned by the Employee.
Neither the Employee, his spouse nor their estates shall have any right to
encumber or dispose of any right to 

                                     -10-
<PAGE>
 
receive payments hereunder, it being understood that such payments and the right
thereto are nonassignable and nontransferable.

     19.  Binding Effect.  Subject to the provisions of Section 18 of this
Agreement, this Agreement shall be binding upon and inure to the benefit of the
Parties hereto, the Employee's heirs and personal representatives, and the
successors and assigns of the Company.

     20.  Governing Law.  This Agreement shall be construed and enforced in
accordance with and governed by the laws of the State of California.

     21.  Prior Employment Agreements.  Employee represents and warrants to the
Company that he has fulfilled all of the terms and conditions of all prior
employment agreements to which he may be or have been a party, and at the time
of execution of this Agreement is not a party to any other employment agreement.

     22.  Parole Evidence.  This Agreement constitutes the sole and complete
agreement between the Parties hereto with respect to the subject matter hereof,
and no verbal or other statements, inducements or representations have been made
to or relied upon by either Party, and no modification hereof shall be effective
unless in writing signed and executed in the same manner as this Agreement,
provided, however, the amount of compensation to be paid Employee for services
to be performed for Company may be changed from time to time by the Parties
hereto by written agreement without in any other way modifying, changing or
affecting this Agreement and the performance by the Employee of any of the
duties of his employment with the Company.  Written notification of any
modification of compensation paid or payable to the Employee for his services
shall be conclusively deemed to be a ratification and confirmation of this
Agreement amended by such change in compensation unless the Employee shall
object in writing with ten (10) days after such written notification from the
Company.

     23.  Waiver.  Any waiver to be enforceable must be in writing and executed
by the Party against whom the waiver is sought to be enforced.

     24.  Arbitration and Limitation on Claims.  Any controversy, dispute or
claim arising out of, in connection with, or in relation to, the interpretation,
performance or breach of this Agreement, including, without limitation, the
validity, scope and enforceability of this Section which cannot first be settled
through ordinary negotiation between the parties shall be submitted in good
faith to mediation by and in accordance with the Commercial Mediation Rules of
the American Arbitration Association or any successor organization.  In the
event that mediation of such controversy, dispute or claim cannot be settled
through the mediation proceeding, the Parties agree that the controversy,
dispute or claim shall be submitted to binding and final arbitration conducted
in Los Angeles, California  by and in accordance with the then existing Rules
for Commercial Arbitration of the American Arbitration Association or any
successor organization.  Any such arbitration shall be to a three member panel
selected through the rules governing selection and appointment of such panels of
the American Arbitration Association or any successor organization.  The award
rendered by the arbitrators may be confirmed, entered and enforced as a judgment
in any court of competent jurisdiction; however, the parties otherwise waive any
rights to appeal the award except with regard 

                                     -11-
<PAGE>
 
to fraud by the panel. Any such action must be brought within two years of the
date the cause of action accrues. The arbitrators shall award the Party which
substantially prevails in any arbitration proceeding recovery of that party's
attorneys' fees, the arbitrators' fees and all costs in connection with the
arbitration from the party who does not substantially prevail. The parties'
remedies are limited solely to the specific remedies provided in this Agreement.
The parties waive any entitlement to punitive damages, consequential damages and
lost profits and will limit any damage claim to actual economic damages
incurred. Nothing in this Section 24 shall restrict any party's ability to seek
injunctive or other equitable relief in any court of competent jurisdiction
prior to initiating mediation or arbitration. In the event that such injunctive
or equitable relief is sought by any party, such party is specifically entitled
to enforce the appropriate provisions of this Agreement in obtaining such relief
in any court of competent jurisdiction and, thereafter, submit the remaining
controversy, dispute or claim to arbitration in accordance with this Section 24.

     25.  Attorney's Fees.  If any litigation is instituted to enforce or
interpret the provisions of this Agreement or the transactions described herein,
the prevailing Party in such action shall be entitled to recover its reasonable
attorneys' fees and other costs from the other Party hereto.

     26.  Drafting.  All Parties hereto acknowledge that each was actively
involved in the negotiation and drafting of this Agreement and that no law or
rule of construction shall be raised or used in which the provisions of this
Agreement shall be construed in favor or against any Party hereto because one is
deemed to be the author thereof.

     27.  Multiple Counterparts. This Agreement may be executed in multiple
counterparts, each of which shall have the force and effect of an original, and
all of which shall constitute one and the same agreement.

company of the Secured Party (the "Parent").

                              W I T N E S S E T H:
                              - - - - - - - - - - 

     WHEREAS, pursuant to the Purchase Agreement the Pledgor has agreed to sell
all of the issued and outstanding common stock of Burton House, Inc., a
California corporation doing business as Ziskind, Greene, Watanabe & Nason (the
"Company"), to Secured Party upon the terms and conditions contained in the
Purchase Agreement; and

     WHEREAS, Pledgor has certain obligations under the Purchase Agreement,
including, but not limited to, the obligation of Pledgor to indemnify Secured
Party for any breaches of representations and warranties of Pledgor contained in
the Purchase Agreement; and

     WHEREAS, pursuant to the terms of the Purchase Agreement and as partial
consideration for the purchase of the common stock of the Company by the Secured
Party, the Pledgor has been issued shares of common stock , $.01 par value per
share, of the Parent (the "Common Stock"); and

     WHEREAS, the terms of the Purchase Agreement provide for the Pledgor to
pledge a portion of the shares of Common Stock to the Secured Party in order to
secure the obligations of Pledgor under the Purchase Agreement;

     NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties agree as follows:

     1.   Pledge of Common Stock.  Pledgor hereby pledges and grants to Secured
Party a security interest in 41,764 shares (the "Shares") of the Common Stock
issued pursuant to the Purchase Agreement, which shall attach immediately upon
the issuance of such Shares to Pledgor in accordance with the terms of the
Purchase Agreement.  Immediately upon receipt of the Shares, Pledgor shall be
required to deliver to Secured Party the certificate or certificates
representing the Shares in order that Secured Party might perfect its security
interest therein.  The Pledgor and the Secured Party hereby acknowledge and
agree that the value of the Shares shall be deemed to be $8.50 per share of
Common Stock; provided, however, that if Parent has successfully consummated 

                                      -1-
<PAGE>
 
a Public Offering, as such term is defined in the Purchase Agreement, of its
shares of Common Stock, then it shall mean the average public trading price of
each share of Common Stock over the five (5) most recent business days falling
prior to the date of delivery by the Secured Party to the Pledgor of the notice
of an event requiring an Offset, as such term is defined in the Purchase
Agreement (the "Agreed Value").  Pledgor shall possess all voting rights
pertaining to the Shares, so long as an Event of Offset, as hereinafter defined,
has not occurred, or if an Event of Offset has allegedly occurred but is being
disputed by the parties hereto prior to submission to arbitration in accordance
with Section 9(N) of the Purchase Agreement and Section 17 hereof, and Secured
Party shall have no voting rights that may be presently or hereafter
attributable to the Shares.  In addition, so long as an Event of Offset has not
occurred, or if an Event of Offset has allegedly occurred but is being disputed
by the parties hereto prior to submission to arbitration in accordance with
Section 9(N) of the Purchase Agreement, then Pledgor shall have the right to
receive all dividends, if any, on the Shares, and Pledgor shall be entitled to
receive all proceeds upon liquidation of the Shares, if any, as well as all
other rights with respect to the Shares except for the right to transfer title
thereto.  Notwithstanding the foregoing, if an Event of Offset has occurred and
(i) has been resolved, either by failure to timely dispute it as required by
Section 9(N) of the Purchase Agreement, by agreement or by arbitration decided
in favor of Secured Party (a "Resolved Event of Offset") or (ii) has been
submitted to arbitration in accordance with Section 9(N) of the Purchase
Agreement which arbitration is still pending or in process (a "Continuing Event
of Offset"), then Secured Party shall have the right to designate a
representative or trustee to vote those shares of Shares covered by or subject
to the Resolved Event of Offset or Continuing Event of Offset (the "Offset
Shares"), to receive all dividends and liquidation proceeds with respect to the
Offset Shares, and to receive all other rights with respect to the Offset
Shares.

     2.   Representations and Warranties.  Pledgor hereby represents, warrants
and covenants to and with Secured Party that:

          (a) Pledgor will not, without the written consent of Secured Party,
     sell, contract to sell, encumber, or dispose of the Shares or any interest
     therein until this Pledge Agreement and all obligations under the Purchase
     Agreement have been fully satisfied.

          (b) No consent of any party is necessary for the Pledgor to perform
     his obligations hereunder, or if any such consent is required, such consent
     has been received prior to the execution of this Pledge Agreement.

     3.   Event of Offset.  Each delivery by Secured Party to the Pledgor of a
notice of a claim of offset pursuant to Section 8(b) of the Purchase Agreement
shall constitute an Event of Offset ("Event of Offset") under this Pledge
Agreement.

     4.   Remedies.

          (a) Upon the occurrence of a Resolved Event of Offset, Secured Party
     may, at its option, exercise with reference to the Shares any and all of
     the rights and remedies of a secured party under the Uniform Commercial
     Code as adopted in the State of California and as otherwise granted therein
     or under any other applicable law or under any other agreement 

                                      -2-
<PAGE>
 
     executed by Pledgor, including, without limitation, the right and power to
     sell, at public or private sale(s), or otherwise dispose of or keep the
     Shares and any part or parts thereof, or interest or interests therein
     owned by Pledgor, in any manner authorized or permitted under this Pledge
     Agreement or under the Uniform Commercial Code, and to apply the proceeds
     thereof toward payment of any costs and expenses and attorneys' fees and
     legal expenses thereby incurred by Secured Party, and toward payment of the
     obligations under the Purchase Agreement in such order or manner as Secured
     Party may elect. Notwithstanding anything to the contrary contained herein,
     the Secured Party shall only foreclose on that portion of the Shares that
     is reasonably necessary in the reasonable good faith judgment of the
     Secured Party in order to satisfy the amount of the claim constituting the
     Resolved Event of Offset. For purposes hereof, the Agreed Value of the
     Shares shall be deemed to be the value that the Secured Party is receiving
     on the foreclosure of the Shares and Secured Party shall not be entitled to
     foreclose on more Shares than is necessary to recover all damages resulting
     from the Resolved Event of Offset to which Secured Party is entitled
     hereunder.

          (b) Secured Party is hereby granted the right, at its option, after a
     Continuing Event of Offset, to transfer at any time to itself or its
     nominee the securities or other property hereby pledged, or any part
     thereof, and to thereafter exercise all voting rights with respect to such
     Shares so transferred and to receive the proceeds, payments, monies, income
     or benefits attributable or accruing thereto and to hold the same as
     security for the obligations hereby secured, or at Secured Party's
     election, to apply such amounts to the obligations, only if due, and in
     such order as Secured Party may elect or Secured Party may, at its option,
     without transferring such securities or property to its nominee, exercise
     all voting rights with respect to the securities pledged hereunder and vote
     all or any part of such securities at any regular or special meeting of
     shareholders.

          (c) Pledgor hereby agrees to cooperate fully with Secured Party in
     order to permit Secured Party to sell, at foreclosure or other private
     sale, Pledgor's interest in the Shares pledged hereunder as provided in
     this Pledge Agreement.  Specifically, Pledgor agrees to deliver to Secured
     Party the certificate or certificates representing the Shares if Pledgor
     has possession at that time, to fully comply with the securities laws of
     the United States and of the State of California and to take such other
     action as may be necessary to permit Secured Party to sell or otherwise
     transfer the securities pledged hereunder in compliance with such laws.

          (d) Prior to the exercise by Secured Party of any of its remedies
     hereunder resulting in a sale or transfer of Shares, Pledgor may elect to
     pay the full amount of any Resolved Event of Offset in cash.  Upon the
     receipt of any such full cash payment, Secured Party shall not be entitled
     to pursue any other remedy with respect to such Resolved Event of Offset.

     5.   Termination. This Pledge Agreement shall continue as security for the
payment or satisfaction of the obligations under the Purchase Agreement until
the earliest to occur of: (i) termination of this Pledge Agreement as provided
in Section 19 below, (ii) the date upon which none of the representations and
warranties of Pledgor contained in the Purchase Agreement survive and 


                                      -3-
<PAGE>
 
all covenants and obligations of Pledgor under said Purchase Agreement have been
fully and properly performed with respect thereto or (ii) three (3) years after
the date hereof, provided that Secured Party has not given Pledgor notice of an
Event of Offset which has not been satisfied by Pledgor, or if there is an Event
of Offset, the pledge shall continue only to the extent of the number of Shares
based on the Agreed Value equal to the amount of damages reasonably expected by
Secured Party to be caused by the Event of Offset; provided however, (a) upon
the closing of an initial public offering of the Common Stock by the Parent
("IPO"), in the event the number of Shares pledged pursuant hereto multiplied by
the price to public ("Price to Public") of the shares of Common Stock in the IPO
exceeds the amount of $355,000, Secured Party shall, within 15 days, release
from the pledge evidenced hereby such integral number of Shares determined by
subtracting from (i) the original number of Shares pledged hereunder (ii) the
number of shares determined by dividing $355,000 by the Price to Public, and the
remaining shares of Shares shall remain pledged under the terms and conditions
of this Pledge Agreement and (b) upon the expiration of six months, two years
and three years after the date of this Pledge Agreement (each a "Release Date"),
the following provisions shall apply: (x) if no Event of Offset exists on such
Release Date or such Event of Offset has been otherwise resolved, the Secured
Party shall release one-third (1/3) of the number of Shares pledged hereunder
following any release pursuant to (a) above from the pledge established hereby,
and the remaining shares of Shares shall remain pledged under the terms and
conditions of this Pledge Agreement; or (y) if an Event of Offset exists, the
amount of Damages resulting from such Event of Offset shall be determined, and
on the first Release Date, the second Release Date and the third Release Date,
one third (1/3), one half (1/2) and all of the remaining Shares, respectively,
that have not been Offset against shall be released from the pledge established
hereby and delivered to the Pledgor and the remaining shares of Shares shall
remained pledged under the terms and conditions of this Pledge Agreement.

     6.   Release from Pledge.  Upon the termination of this Pledge Agreement,
Secured Party shall immediately release its security interest in the Shares.  In
addition, Secured Party shall deliver the certificate or certificates
representing the Shares to Pledgor if Secured Party has possession of such
certificates at that time.  Upon such occurrence, the security interest of
Secured Party shall automatically terminate and Secured Party shall thereafter
have no interest whatsoever in the Shares.

     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 if (and then
two business days after) it is sent by registered or certified mail, return

                                  EXHIBIT F-1


                      FORM OF OPINION OF SELLERS' COUNSEL

     Based upon our examination and consideration of the Agreement, the
Employment Agreement, the Stock Pledge Agreement, the Registration Rights
Agreement and the Shareholders' Agreement  (collectively, the "Transaction
Documents"), and in reliance thereon, and subject to the assumptions,
exceptions, qualifications and limitations set forth herein, we are of the
opinion that:

     1.   The Company is a California corporation, duly organized, validly
          existing and in good standing under the laws of the State of
          California, and has all necessary power and authority and all material
          licenses, permits and authorizations necessary to own and use the
          properties owned and used by it and to operate its business as now
          owned and operated by it. The Company is not qualified to do business
          in any other jurisdiction, nor does the nature of its business nor the
          location of any of its employees or assets require such qualification.
          All of the outstanding shares of capital stock of the Company have
          been duly authorized and validly issued and are fully paid and
          nonassessable and were not issued in violation of the preemptive
          rights of any Person.

     2.   Sellers have the full right, power and legal capacity to execute,
          deliver and perform their obligations under the Transaction Documents.
          Each such Transaction Document has been duly executed and delivered by
          the appropriate Seller, and is binding on each Seller and enforceable
          against each Seller in accordance with its terms, except as limited by
          bankruptcy laws, insolvency laws, and other similar laws affecting the
          rights of creditors generally.

     3.   Except for such as have been obtained and provided to Buyer, neither
          the Company nor Sellers needs to give any notice to, make any filing
          with, or obtain any authorization, consent or approval, or make any
          declaration or filing with any government or governmental agency or
          regulatory body or other third party in connection with the execution
          and delivery of the Transaction Documents or the performance by
          Sellers of their obligations thereunder.

     4.   The execution and the delivery of the Transaction Documents by the
          Sellers, and the consummation of the transactions by the Sellers as
          contemplated hereby, will not (i) violate any constitution, statute,

                                  EXHIBIT F-2


                       FORM OF OPINION OF BUYER'S COUNSEL

     Based upon our examination and consideration of the Agreement, the
Employment Agreement, the Stock Pledge Agreement, the Registration Rights
Agreement and the Shareholders' Agreement  (collectively, the "Transaction
Documents"), and in reliance thereon, and subject to the assumptions,
exceptions, qualifications and limitations set forth herein, we are of the
opinion that:

     1.   Buyer is a corporation duly incorporated, validly existing and in good
          standing under the laws of the State of California with the corporate
          power and authority to own its assets and to transact its businesses
          as now being conducted. Buyer is in good standing in all jurisdictions
          in which the character of the properties and assets now owned or held
          by it or the nature of the businesses now conducted by it requires it
          to be so licensed or qualified and where the failure so to qualify
          would affect materially and adversely the business, financial
          condition or results of operations of Buyer.

     2.   The Parent is a corporation duly incorporated, validly existing and in
          good standing under the laws of the State of Texas with the corporate
          power and authority to own its assets and to transact its business as
          now being conducted. The Parent is in good standing in all
          jurisdictions in which the character of the properties and assets now
          owned or held by it or the nature of the business now conducted by it
          requires it to be so licensed or qualified and where the failure so to
          qualify would affect materially and adversely the business, financial
          condition or results of operations of the Parent.

     3.   The Transaction Documents to which either Buyer or Parent are a party
          have been duly and validly authorized, executed and delivered and are
          valid and binding on either the Buyer or Parent, as applicable, and
          enforceable in accordance with their terms, except as limited by
          bankruptcy laws, insolvency laws, and other similar laws affecting the
          rights of creditors generally.

     4.   All of the outstanding Parent Shareshave been duly authorized validly
          issued and, to our knowledge, are fully paid and nonassessable. The
          Parent Shares to be issued to the Sellers pursuant to the Agreement
          have been duly authorized and, when issued to the Sellers in
          accordance with the terms of the Agreement will be validly issued,
          fully paid and nonassessable, subject to the terms of the Stock Pledge
          Agreement and Section 8B of the Agreement.

     5.   Except for such as have been obtained and delivered to Sellers at
          closing and except where the failure to obtain such authorization,
          approval or consent or to take such action or make such filing would
          not have a material adverse effect on Buyer or Parent, as applicable,
          to our knowledge no authorization, approval or consent of or
<PAGE>
 
          declaration or filing with any governmental authority or regulatory
          body is necessary or required of the Buyer or the Parent in connection
          with the execution and delivery of the Transaction Documents by either
          and the performance by either Buyer or Parent of its obligations
          thereunder.

     6.   The execution and delivery of the Transaction Documents to which it is
          a party by each of the Buyer and the Parent and the performance of its
          obligations thereunder do not to our knowledge (i) violate any
          provision of any existing law or regulation applicable to each or (ii)
          violate any order, judgment, award or decree of any court, arbitrator
          or governmental authority applicable to each or (iii) violate the
          charter or bylaws of, or any securities issued by, each or (iv)
          violate any mortgage, indenture, lease, contract or other agreement
          known to us to which either is a party or by which either the Buyer or
          Parent or any of their assets is bound.

     7.   To our knowledge, neither the Buyer nor the Parent is in default under
          any material order, judgment, award or decree of any court, arbitrator
          or governmental authority binding upon or affecting it or by which its
          assets may be bound or affected, and to our knowledge, no such order,
          judgment, award or decree materially adversely affects the ability of
          the Buyer or the Parent to carry on its respective business as now
          conducted or perform its respective obligations under the Transaction
          Documents.

     8.   To our knowledge, except as disclosed in the Transaction Documents and
          the schedules thereto, no litigation, investigation or administrative
          proceeding of or before any court, arbitrator or governmental
          authority is pending or threatened against the Buyer or Parent or
          their assets (a) with respect to the Transaction Documents or the
          transactions contemplated thereby, or (b) that, if adversely
          determined, would have a material adverse effect on the business or
          financial condition of Buyer or Parent or their assets.
