five Business Days prior to the Closing Date, the Seller shall cause to be
delivered to Buyer a statement of estimated Acquired Assets and Assumed
Liabilities (the "Estimated Closing Statement of Net Assets") as of the date

to Section II.3(c), except that it shall be unaudited. The term "Estimated
Closing Date Net Assets" shall mean the book value of the Acquired Assets set

increase to the Cash Purchase Price pursuant to this Section II.3(b) plus
interest from the Closing Date at the Prime Rate (as hereinafter defined) shall
be paid by the Seller or Buyer, as the case may be, by wire transfer in
immediately available funds within five (5) Business Days after the Final

is determined by the Neutral Auditor (as hereinafter defined). For purposes of
this Agreement, "Prime Rate" means the rate of interest announced from time to
time by Bank of America as its prime rate of interest.

      (c) Preparation of Closing Statement of Net Assets. As soon as

the Buyer shall cause to be prepared a statement of net assets for the Business
consisting of the Acquired Assets and the Assumed Liabilities, as of the close
of business on the date three (3) Business Days prior to the Closing Date

consummated the transactions contemplated thereby on such date (the "Closing
Statement of Net Assets"). The Closing Statement of Net Assets will be prepared
in accordance with United States generally accepted accounting principles
("GAAP") applied on a basis consistent with the September Balance Sheet through
full application of the policies and procedures used in preparing the September
Balance Sheet and with changes in contract estimates at completion ("EAC's") and
estimates to complete ("ETC's") determined on a basis consistent with the method
used for the determination of the September Balance Sheet, and will, at the
option of the Buyer, be audited by an independent public accounting firm
selected by Buyer (the "Auditor"). The Closing Statement of the Net Assets shall
be accompanied by an Auditor's report based upon the audit of the Audited
Closing Statement of Net Assets stating that such statement presents fairly, in
all material respects, the Acquired Assets and Assumed Liabilities presented on
such statement as provided for in this Agreement at the third Business Day prior
to the Closing Date in conformity with GAAP consistently applied with the
September Balance Sheet, except as modified by any modification which is
mutually agreed upon by the parties hereto. Buyer shall provide the Auditor
access to the Books and Records as may reasonably be required for the
preparation of the Closing Statement of Net Assets. Buyer shall be responsible
for the costs and expenses of the Auditor in preparing the Closing Statement of
Net Assets.

      II.4 Post-Closing Payment.

      (a) As additional consideration for the Acquired Assets ("Additional
Consideration"), Buyer shall make the payments or deliveries to the Seller
required pursuant to this Section II.4. With respect to each of fiscal years of
the Acquired Company ending December 31, 1998, 1999 and 2000, respectively.
Buyer shall pay to the Seller in aggregate for any such fiscal year an amount in
cash (subject to Section II.4(c)) equal to the product of (i) $3,000,000 for
1998, $3,300,000 for 1999 and $3,630,000 for 2000 and (ii) a percentage (the
"Percentage") calculated by dividing (x) EBIT (as defined below) for the
Acquired Company for each in each of fiscal 1998, 1999 and 2000 by (y)
$8,800,000 for 1998, $10,300,000 for 1999 and $12,300,000 for 2000, respectively
provided that the maximum Percentage for any fiscal year shall be 120%.


                                       -8-


No Additional Consideration will be due to the Seller under this Section II.4 in
respect of any fiscal year if the Percentage for that fiscal year shall be less
than 60%. "EBIT" means for any fiscal year operating income of the Acquired
Company before interest and income taxes; provided that for purposes of
calculating EBIT there shall be eliminated (i) the effect of any purchase
accounting adjustments (including any increase in depreciation or amortization
of tangible or intangible assets of the Business resulting from a write-up of
the Acquired Assets for accounting purposes) in connection with the acquisition
of the Company, (ii) all costs and expenses paid in connection with financing
and refinancing the purchase of the Company, (iii) all operating income, if any,
attributable to the SWEATS contract, (iv) all gains (or losses) from
extraordinary items and investments, (v) the cumulative effect of changes in
accounting principles and (vi) the effect (whether revenue or expense) as a
result of any allocation by Buyer of any Buyer-incurred general and
administration expenses or management fees (but only to the extent such
allocation of expenses or fees exceeds amounts which would be an expense of the
operation of the Acquired Company on a stand-alone basis consistent with the
Company's method of operation prior to February 10, 1998). In the event of the
disposition or discontinuation of any of the Acquired Company's current
businesses or operations or the addition of any business or operation to the
Acquired Company, the target EBIT amount referred to above shall be adjusted
appropriately (determined in good faith by the Buyer, in consultation with the
Seller) to reflect such disposition, discontinuation or addition, for purposes
of calculating the Percentage.

      (b) For each of the 1998, 1999 and 2000 fiscal years, Buyer shall, no
later than 45 days following the availability of financial statements for such
period, prepare and deliver to Seller a report (the "EBIT Report") reflecting in
reasonable detail Buyer's calculation of EBIT for the applicable fiscal year
(including any adjustments to Buyer's financial statements made in connection
with such calculation), together with a copy of the financial statements from
which such calculation is derived. EBIT will be calculated in accordance with
GAAP applied on a basis consistent with the Financial Statements (as defined in
Section II.6) and with changes to EAC's and ETC's determined on a basis
consistent with the methods used in the Financial Statements.

      (c) Any payment of Additional Consideration with respect to any fiscal
year shall be payable to the Seller within 30 days after the date on which the
calculation of EBIT for such fiscal year shall have been finally determined
pursuant to this Section II.4 and Section II.5; provided that no such payment of
Additional Consideration (except portions thereof as to which Early Cash Payment
Elections (as defined in Section II.4(e)) have been received by Buyer in
accordance with Section II.4(e)) with respect to any fiscal year shall be
payable by Buyer pursuant to this Section II.4 prior to the earlier of (i) the
date 60 days following the completion of the initial sale to the public pursuant
to an effective registration statement (other than a registration statement on
Form S-4 or Form S-8 or any similar or successor form) (the "Initial Public
Offering") filed under the Securities Act of 1933, as amended (the "Securities
Act"), of shares of the Class A Common Stock, par value $.0l per share of L-3
Communications Holdings Inc. ("Holdings") (or such other class of common stock
of Holdings issued to the holders of such Class A Common Stock in connection
with a reclassification thereof) ("Class A Common Stock") and (ii) September 30,
2001. Seller shall not be permitted to elect to receive shares in lieu of
Additional Consideration for any fiscal year in an amount less than $250,000
unless the Seller is electing to receive shares for all of such Additional
Consideration for such fiscal year. Each cash payment pursuant to this Section
II.4 shall be made by wire transfer of immediately


                                       -9-


available funds to the account designated by the Seller in a written notice to
Buyer given at least 5 Business Days prior to the date of payment.

      (d) Prior to the date of any payment of Additional Consideration pursuant
to Section II.4(b) (other than payments pursuant to Early Cash Payment
Elections), Buyer shall offer the Seller the opportunity to elect to receive, in
lieu of such payment, any Additional Consideration in the form of shares of
Freely Tradable (as defined below) Class A Common Stock. Such offer of such
shares shall be made in a transaction meeting the requirements of the Securities
Act (and any applicable state securities laws). The number of shares of Class A
Common Stock to be delivered if the Seller elects to receive such shares
pursuant to such offer shall be determined by dividing (i) the amount of such
payment of Additional Consideration by (ii) $20 to the extent such Additional
Consideration relates to fiscal 1998, $22 to the extent such Additional
Consideration relates to fiscal 1999 and $24.20 to the extent such Additional
Consideration relates to fiscal 2000. In the event of any change in the
outstanding Class A Common Stock by reason of stock split, stock combination,
reclassification or similar event, the number of shares to be delivered pursuant
to the preceding sentence shall be adjusted appropriately (e.g., if the
outstanding shares of Class A Common Stock are split on a two-for-one basis, the
$20, $22 and $24.20 amounts referred to in clause (ii) would be adjusted to be
$10, $11 and $12.10, respectively). In the event that the Initial Public
Offering is not completed by August 1, 2001, no offer to elect to receive shares
of Class A Common Stock shall be made pursuant to this Section II.4(d). If the
Seller elects to receive shares pursuant to this Section II.4(d) such shares
will be delivered by registered mail to the address designated by the Seller in
a written notice to Buyer given at least five (5) Business Days prior to the
date of delivery. No fractional shares of Class A Common Stock will be issuable
pursuant to this Section II.4. In lieu thereof, any person who would otherwise
be entitled to a fractional share pursuant to the provisions hereof shall
receive an amount in cash equal to the amount of Additional Consideration which
would have been payable in cash with respect to such fraction. For purposes of
this Section II.4, "Freely Tradable" shall mean Class A Common Stock which (a)
may be sold (without legal restriction) to any member of the public, including a
sale by or through a securities exchange and/or broker-dealer, without the
necessity of (I) obtaining an opinion of counsel, obtaining permission or
authorization of the United States Securities & Exchange Commission or any state
securities administrator, (II) providing any advance notice to any such body or
(III) taking other action to remove any legend or legend condition applicable to
such shares of Class A Common Stock that would delay the sale thereof and (b) is
not subject to any material delay in attempting the sale thereof on a public
securities exchange due to any attribute of the Class A Common Stock.

      (e) At any time and from time to time, the Seller shall have the right, by
written notice (an "Early Cash Payment Election") to Buyer, to elect to require
Buyer to pay to the Seller the cash amount of any Additional Consideration
payable to the Seller pursuant to Section II.4(c), with the date of payment
being determined pursuant to the first sentence of such Section without regard
to the proviso thereto.

      (f) Upon a Change of Control (as hereinafter defined) that occurs prior to
the earlier to occur of the dates referred to in clauses (i) and (ii) of the
proviso to the first sentence of Section II.4(c), the Seller shall receive in
connection with such Change of Control all Additional Consideration payable to
the Seller pursuant to Section II.4(c) but not then paid by reason of the


                                      -10-


proviso contained in the first sentence of such Section prior to the date of
such Change of Control the amount and kind of consideration the Seller would
have received in respect of the shares of Class A Common Stock which the Seller
would have been entitled to elect to receive pursuant to subsection (d) of this
Section II.4 if there had been an Initial Public Offering immediately prior to
the date of the Change of Control. Such amount shall be payable at such time as
the holders of Class A Common Stock receive consideration in connection with
such Change of Control. In the event of a Change of Control, notwithstanding
anything to the contrary contained herein, any Additional Consideration which
becomes payable pursuant to Section II.4(c) following the date of such Change of
Control shall be payable in cash.

      For purposes of this Section II.4(f), "Change of Control" shall mean (i)
an acquisition by any person (other than stockholders of Holdings as of the
Closing Date or any of their affiliates) of more than 50% of the combined voting
power of the outstanding voting securities entitled to vote generally of
Holdings or (ii) the sale of substantially all of the direct or indirect assets
of Holdings to any person (other than stockholders of Holdings as of the Closing
Date or any of their affiliates).

      (g) The rights of the Seller under this Section II.4 shall be assignable
(in whole or in part) by Seller, subject to the following requirements: (i) any
such assignment shall be made prior to the date six months following the Closing
Date; (ii) if such assignment is to more than one person or entity, (1) any
payment or delivery pursuant to this Section II.4 shall be pro rata, based on
the relative percentage of Additional Consideration to which such person or
entity is entitled hereunder, (2) the $250,000 limitation contained in Section
II.4(c) shall apply to each such person or entity and (3) adequate provision
shall be made in connection with such assignment so that one assignee in
connection with any disputes concerning the calculation and determination of any
amounts payable pursuant to this Section II shall be authorized to resolve any
and all disputes with the Buyer on behalf of all assignees; and (iii)
notwithstanding any such assignment, the right of offset against Seller referred
to in the last sentence of Section VI.2(a) shall continue to apply
notwithstanding such assignment (i.e., a claim against the Seller under Section
VI.2 may be satisfied by exercising such right of offset against amounts due to
an assignee of Seller).

      II.5 Dispute Resolution.

      (a) Review of Closing Statement of Net Assets and EBIT Report. After
receipt of the Closing Statement of Net Assets or the EBIT Report, Buyer or the
Seller, as the case may be, shall have thirty (30) days to review it. Buyer or
the Seller, as applicable, and their respective authorized representatives shall
have full access to all Books and Records and employees of the Company and, with
respect to the Closing Statement of Net Assets, the Auditor to the extent
required to complete their review of the Closing Statement of Net Assets or the
EBIT Report, as applicable, including Auditor work papers used in preparation or
the Closing Statement of Net Assets. Unless the Buyer delivers written notice to
the Seller, or the Seller delivers written notice to Buyer, on or prior to, the
30th day after receipt of the Closing Statement of Net Assets or the EBIT Report
specifying in reasonable detail all disputed items and the basis therefor, the
parties shall be deemed to have accepted and agreed to the Closing Statement of
Net Assets or the EBIT Report. The parties shall, within thirty (30) days
following the date of such notice (the "Resolution Period"), attempt to resolve
their differences and any resolution by them as to any


                                      -11-


disputed amount shall be final, binding, conclusive and nonappealable for all
purposes under this Agreement.

      (b) Resolution. If at the conclusion of the Resolution Period the parties
have not reached an agreement on the objections, then all amounts remaining in
dispute may, at the election of either party, be submitted to Price Waterhouse
or another large international accounting firm not otherwise engaged by either
party (the "Neutral Auditor"). Each party agrees to execute if requested by the
Neutral Auditor, a reasonable engagement letter. All fees and expenses relating
to the work, if any, to be performed by the Neutral Auditor shall be borne

and agents) from and against any and all Taxes for or in respect of each of the
following (excluding, in all cases, Taxes included within the definition of
Assumed Liabilities):

            (i) any and all Taxes with respect to any taxable period or a
      portion thereof, of the Company (or any predecessor) ending on or before
      the close of business on the date three Business Day's prior to the
      Closing Date;

            (ii) with respect to any and all Taxes of any member of a
      consolidated, combined or unitary group of which the Company (or any
      predecessor) is or was a member on or prior to the close of business on
      the date three Business Days prior to the Closing Date by reason of the
      liability of the Company pursuant to Treasury Regulation Section
      1.1502-6(a) (or any analogous or similar state, local or foreign law or
      regulation), as a transferee or successor, by contract, or otherwise;

            (iii) any Taxes arising out of a breach of the representations and
      warranties contained in Section III.15; and

            (iv) any payments required to be made after the Closing Date under
      any Tax sharing, Tax indemnity, Tax allocation or similar contracts
      (whether or not written), to


                                      -30-


      which the Company or any predecessor was obligated, or was a party, on or
      prior to the close of business on the date three Business Days prior to
      the Closing Date.

      (c) Notification; Control of Proceedings. Buyer shall promptly give to the
Seller written notice if it becomes aware of any liability, loss, damage, claim,
cost and expense with respect to which indemnity may be asserted; provided that
the failure to give prompt notice will not release the Seller from liability
hereunder, except to the extent they are actually prejudiced thereby. If any
claim is made by a third person or an action or proceeding commenced for which
Buyer shall seek indemnity from Seller, Buyer shall give to the Seller
reasonable written notice of the claim and request Seller to defend the same.
Seller shall have the right to defend against such liability at their expense,
and shall give written notice to Buyer of the commencement of such defense with
reasonable promptness after the giving of the written notice of the claim by
Buyer. Buyer shall be entitled to participate with Seller in such defense, but
shall not be entitled in any way to release, waive, settle, modify or pay such
claim without the written consent of the Seller, if Seller have assumed such
defense. In the event Seller does not assume the defense of the matter as
provided above, or does not notify Buyer of its election to defend such a matter
within 30 days, Buyer shall have the full right to defend against such liability
in such manner as it may deem appropriate. In the event Seller shall assume the
defense, Buyer shall cooperate in the defense of such action, and the records of
each shall be available to the other with respect to such defense, provided,
however, that the Seller shall not, in the defense of any such action, consent
to the entry of any judgment or enter into any settlement where such entry of
judgment or settlement does not include a provision releasing the Buyer from all
liability with respect to such action or that provides for a remedy other than
the payment of money damages, except with the written consent of Buyer, such
consent not to be unreasonably withheld or delayed.

      (d) Limitation on Indemnification. Notwithstanding the provisions of
Sections VI.2(a) (except with respect to (A) clauses (ii), (iii) and (iv) of
Section VI.2(a) and (B) Taxes as provided under Section VI.2(b)), (i) Seller
shall not be liable to Buyer on account of any breach of any warranty or
representation by Seller in this Agreement until the aggregate amount of all
claims against Seller for which indemnification would have been available
hereunder but for the application of the limitation set forth in this clause (i)
for all breaches exceeds one percent (1%) of the Cash Purchase Price and then
only for the amount by which such aggregate cumulative liability is in excess of
one percent (1%) of the Cash Purchase Price; and (ii) in no event shall Seller's
obligations to Buyer under Section VI.2(a)(i) exceed, in the aggregate,
$5,000,000.

      (e) Survival. The indemnification obligations of Seller under this Section
VI.2 (except with respect to indemnification pursuant to Section VI.2(a)(ii),
(iii) and (iv)) shall terminate on June 30, 1999 as to any claim not asserted
prior to such date, except that the indemnification obligations of Seller for
(x) a breach of Sections III.1, III.2, III.3, III.5 and III.15 and (y) for Taxes
under Section VI.2(b) shall not terminate until the expiration of the sixty-day
period after the expiration of the applicable statute of limitations as to any
claim not asserted prior to such date and that the indemnification obligations
of Seller for a breach of Sections III.4, III.11 and III.16 shall terminate
three (3) years after the date hereof as to any claim not asserted prior to such
date. The indemnification obligations of Seller (I) under Section VI.2(a)(ii)
shall terminate ten (10) years after the date hereof and (II) under Section
VI.2(a)(iv) shall terminate on June 30, 2000, in each case as to any claim not
asserted prior to such date.


                                      -31-


      (f) Indemnification Provisions for Benefit of Seller.

            (i) In the event Buyer breaches (or in the event any third party
      alleges facts that, if true, would mean Buyer has breached) any of its
      representations, warranties, and covenants contained in this Agreement or
      in any of the Transaction Documents, then the Buyer agrees to indemnify
      Seller and its affiliates (and their respective officers, directors,
      employees and agents) from and against the entirety of any Losses (up to
      but not in excess of the Cash Purchase Price) Seller or its affiliates
      (and their respective officers, directors, employees and agents) may
      suffer through and after the date of the claim for indemnification
      (including any Losses Seller or its affiliates (and their respective
      officers, directors, employees and agents) may suffer after the end of any
      applicable survival period) resulting from, arising out of, or caused by
      the breach (or the alleged breach).

            (ii) Notwithstanding anything to the contrary herein contained, (i)
      Buyer will indemnify, defend and hold harmless Seller and its affiliates
      (and their respective officers, directors, employees and agents) from and
      against any Losses as a result of claims based on or arising from any
      Assumed Liabilities or the operation of the Business after the Closing
      Date and (ii) such indemnification shall not be limited in time or amount
      or subject to any deductible or cap.

            (iii) Seller or its affiliates shall with reasonable promptness give
      to the Buyer written notice if it becomes aware of any Losses with respect
      to which indemnity may be asserted; provided that the failure to give
      prompt notice will not release the Buyer from liability thereunder, except
      to the extent they are actually prejudiced thereby. If any claim is made
      by a third person or an action or proceeding commenced for which Seller or
      other indemnified parties shall seek indemnity from Buyer, Seller or its
      affiliates shall give to Buyer reasonable written notice of the claim and
      request Buyer to defend the same. Buyer shall have the right to defend
      against such liability at their expense, and shall give written notice to
      Seller of the commencement of such defense with reasonable promptness
      after the giving of the written notice of the claim by Seller or its
      affiliates. Seller or other indemnified parties shall be entitled to
      participate with Buyer in such defense, but shall not be entitled in any
      way to release, waive, settle, modify or pay such claim without the
      written consent of the Buyer, if Buyer has assumed such defense. In the
      event Buyer does not assume the defense of the matter as provided above,
      or does not notify Seller of their election to defend such a matter within
      30 days, Seller or other indemnified parties shall have the full right to
      defend against such liability in such manner as it or they may deem
      appropriate. In the event Buyer shall assume the defense, Seller or other
      indemnified parties shall cooperate in the defense of such action, and the
      records of each shall be available to the other with respect to such
      defense, provided, however, that the Buyer shall not, in the defense of
      any such action, consent to the entry of any judgment or enter into any
      settlement where such entry of judgment or settlement does not include a
      provision releasing the Seller or other indemnified parties from all
      liability with respect to such action or that provides for a remedy other
      than the payment of money damages, except with the written consent of
      Seller or other indemnified parties.

            (iv) The indemnification obligations of Buyer under this Section
      VI.2(f) shall not terminate until the expiration of the applicable statute
      of limitations; provided, however,


                                      -32-


      that the indemnification obligations of Buyer related to any failure of
      Seller to perform or comply with any of its covenants and agreements set
      forth in this Agreement shall terminate ten years from the date hereof as
      to any claim not asserted prior to such date.

      VI.3 Contracts Requiring Consent to Assignment. Notwithstanding anything
in this Agreement, neither this Agreement nor any document or instrument
delivered pursuant hereto shall constitute an assignment of any claim, contract,
agreement, license, lease, commitment, sales order or purchase order or any
claim or right or any benefit arising thereunder or resulting therefrom if an
attempted assignment thereof without the consent of any other Person would
constitute a breach thereof or in any way adversely affect the rights to be
assigned. Until such consent is obtained, or if an attempted assignment
thereunder would be ineffective or would affect the rights of Seller or any
affiliate thereunder so that the Buyer would not in fact receive all such
rights, Seller and the Buyer will cooperate with each other (and, to the extent
required, Seller shall cause its affiliates to cooperate with the Buyer) to
provide for the Buyer the benefits of, and to permit the Buyer to assume all
liabilities under, any such claim, contract, agreement, license, lease,
commitment, sales order or purchase order, including enforcement at the request
and expense of the Buyer for the benefit of the Buyer of any and all rights of
Seller or any affiliate against a third party thereto arising out of the breach
or cancellation thereof by such third party; and any transfer or assignment to
the Buyer by Seller or any affiliate of any property or property rights or any
contract or agreement which shall require the consent or approval of any third
party shall be made subject to such consent or approval being obtained. The
parties shall each use their best efforts to obtain any required consent to
assignment.

      VI.4 Company Plans. From and after the Closing, Buyer agrees to assume
Seller's obligations under and become the plan sponsor of each of the Company
Plans in effect immediately prior to the Closing Date and Buyer shall be
entitled to all rights, obligations and duties of Seller under such Company
Plans and Seller shall cause any assets, set-aside or otherwise, pertaining to
the Company Plans to be transferred to Buyer; such assets shall include, but not
be limited to, qualified trusts, VEBAs, and grantor trusts and insurance
policies. Notwithstanding anything to the contrary herein contained, the
assumption of such obligations is not intended to and shall not be construed to
impair the right or ability of Buyer to unilaterally amend or terminate any such
benefit plans and other fringe benefits, or any Company Plan in effect
immediately prior to the Closing Date, at any time after the Closing Date.

      VI.5 Research and Experimental Expenses. Seller will use its reasonable
best efforts to cause to be furnished to Buyer as soon as reasonably
practicable, but in no event more than 180 days after Closing, all information
reasonably requested relating to the base period research expenses and any other
information to allow Buyer to claim research and experimental credits in
accordance with the relevant sections of the Code and treasury regulations
promulgated thereunder.

                                                            EXHIBIT VIII-2

                              ASSIGNMENT AGREEMENT

      THIS ASSIGNMENT AGREEMENT dated as of March 4, 1998 is entered into by
and between L-3 COMMUNICATIONS CORPORATION, a Delaware corporation
("Assignee"), and FAP TRUST, a Connecticut trust ("Assignor").

                                   WITNESSETH

      WHEREAS, Assignor is a party to a Stock Purchase Agreement dated as of
February 9, 1998 (the "Stock Purchase Agreement") pursuant to which Seller
intends to acquire all of the outstanding capital stock of Ilex Systems, Inc.
(the "Company"); and

      WHEREAS, pursuant to the Stock Purchase Agreement, Assignor, the Company,
all of the stockholders of the Company (the "Sellers") and The First National
Bank of Chicago, a national banking association ("Escrow Agent"), have entered
into that certain Escrow Agreement dated as of February __, 1998 (the "Escrow
Agreement") for the purpose of establishing a fund to satisfy certain
indemnification obligations of the Sellers that may arise under the Stock
Purchase Agreement and to facilitate the payment of the cash purchase price
adjustment contemplated thereby; and

      WHEREAS, Assignor and Assignee have entered into an Asset Purchase
Agreement dated as of February 10, 1998 (the "Asset Purchase Agreement")
pursuant to which Assignee will acquire substantially all of the assets and
assume substantially all of the liabilities of the Company; and

      WHEREAS, in connection with the Asset Purchase Agreement and the
transactions contemplated thereby, Assignor desires to assign to Assignee its
entire right, title and interest in, under and to the Escrow Agreement, and
Assignee desires to take such assignment from Assignor, all upon the terms and
conditions set forth below:

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

      1. Assignment of the Escrow Agreement. Assignor hereby assigns to
Assignee all of Assignor's right, title and interest in, under and to the
Escrow Agreement, and Assignee hereby assumes all of Assignor's duties and
obligations under the Escrow Agreement.

      2. Assertion of Claims Under the Escrow Agreement. Assignor and Assignee
understand that any and all claims which Assignee may have under the Escrow
Agreement will in most instances, but not in all, be based on facts and
circumstances that constitute both breaches of certain representations,
warranties and covenants of Assignor contained in the Asset Purchase Agreement
and breaches of similar representations, warranties and







covenants of the Company and the Sellers contained in the Stock Purchase
Agreement. Accordingly, Assignor and Assignee agree as follows:

            (i) For purposes of this Section 2, capitalized terms used but not
      otherwise defined herein shall have the respective meanings given to them
      in the Escrow Agreement.

            (ii) Assignor shall promptly provide written notice to Assignee
      upon its becoming aware of any facts or circumstances that give rise to a
      breach of representation, warranty or covenant under the Stock Purchase
      Agreement. Assignee shall promptly provide written notice to Assignor
      upon its becoming aware of any facts or circumstances that give rise to a
      breach of representation, warranty or covenant under the Asset Purchase
      Agreement.

            (iii) Assignee agrees that it will promptly provide Escrow Agent
      with a Notice of Claim in all instances where Assignee's claims pursuant
      to the Asset Purchase Agreement may also be asserted by Assignor pursuant
      to the Stock Purchase Agreement (a "Matching Claim"). The following
      procedure shall be followed by Assignor and Assignee in connection with
      each Matching Claim:

                  (a) Upon submission by Assignee to Escrow Agent of a Notice
            of Claim with respect to any Matching Claim, Assignee shall direct
            Escrow Agent in writing to make any disbursements required in
            respect thereof directly to Assignee; and

                  (b) Upon the determination of the amount, if any, payable to
            Assignee with respect to such Matching Claim, whether by
            negotiation or litigation, and disbursement by Escrow Agent to
            Assignee of such amount out of the Escrow Fund in respect of any
            Matching Claim, Assignee agrees that such Matching Claim shall be
            deemed fully paid and satisfied and neither Assignor nor Escrow
            Agent shall have any further liability to Assignee with respect to
            such Matching Claim, nor shall Assignee have any right to seek any
            additional payments out of the Escrow Fund pursuant to the Asset
            Purchase Agreement with respect to such Matching Claim.

            (iv) In consideration of the mutual promises contained in this
      Agreement, Assignee agrees that it will, if known, provide Escrow Agent
      with a Notice of Claim in respect of any and all claims that may be
      asserted by Assignor pursuant to the Stock Purchase Agreement but may not
      be asserted by Assignee pursuant to the Asset Purchase Agreement (an
      "Assignor Claim"). The following procedure shall be followed by Assignor
      and Assignee in connection with each Assignor Claim:

                  (a) Upon submission by Assignee to Escrow Agent of a Notice
            of Claim with respect to any Assignor Claim, Assignee shall direct
            Escrow Agent in writing to make any disbursements required in
            respect thereof directly to Assignee; and


                                      -2-





                  (b) Upon determination of the amount, if any, payable to
            Assignee with respect to such Assignor Claim, whether by
            negotiation or litigation, and disbursement by Escrow Agent to
            Assignee of such amount out of the Escrow Fund in respect of any
            Assignor Claim, Assignee shall within two business days thereafter
            remit to Assignor by certified check or wire transfer to an account
            designated by Assignor in writing an amount equal to the amounts
            disbursed to Assignee with respect to such Assignor Claim, and
            Assignor agrees that its claim shall be deemed fully paid and
            satisfied upon receipt of such certified check or wire transfer and
            that neither Assignee nor Escrow Agent shall have any further
            liability to Assignor with respect to that claim, nor shall
            Assignor have any right to seek any additional payments out of the
            Escrow Fund pursuant to the Stock Purchase Agreement with respect
            to that claim. Assignee shall not in any way be responsible to
            Assignor with respect to any such claim except for the requirement
            to deliver to Assignor amounts disbursed to Assignee with respect
            to such claim from the Escrow Fund.

            (v) Assignee agrees to pursue any Matching Claim only under the
      claims procedures set forth in this Agreement and the Escrow Agreement.

            (vi) Assignee shall promptly deliver to Assignor copies of any and
      all Award Notices, Notices of Claims, Notices of Releases, Objections and
      Withdrawal Notices received by it pursuant to Section 5 of the Escrow
      Agreement.

            (vii) Assignor and Assignee shall cooperate with each other
      regarding the submission of any and all Notices of Claims to Escrow Agent
      in connection with the Escrow Agreement, and each of them agree to take
      any and all such reasonable actions that either of them deem necessary or
      appropriate to otherwise effectuate the purpose and intent of this
      Section 2.

      3. Counterparts. This Agreement may be executed in multiple counterparts,
each of which shall be deemed to be an original but all of which together shall
constitute one and the same instrument.

      4. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

      5. Arbitration. Any dispute under this Agreement which is not settled by
mutual agreement among the parties hereto, shall be finally settled by binding
arbitration in New York, New York, conducted by and in accordance with the
rules then in effect of the Judicial Arbitration and Mediation Service. Each
party shall bear its own costs and attorneys' and witness' fees. The prevailing
party in any arbitration, as determined by the arbitration panel, shall be
entitled to an award against the other party in the amount of the prevailing
party's costs and reasonable attorneys' fees. In making any such award, the
arbitration panel shall take into consideration the outcome of the proceeding
and the reasonableness of the conduct of each such party in connection with the
dispute, in light of


                                      -3-





the facts known to such party at the time such party engaged in such conduct.
