within thirty days after delivery of the Closing Date Balance Sheet, deliver a
notice to the Holder Representative (the "Dispute Notice") setting forth in
reasonable detail the basis of such dispute. If the Dispute Notice is not
delivered within such thirty day period, then the Closing Date Balance Sheet and
the Actual Net Current Assets reflected on the Closing Date Balance Sheet, as so
determined by

- -4-



the Holder Representative and Rainer, shall be the "Final Net Current Assets".
In the event that the Dispute Notice is delivered within such period, Buyer and
the Holder Representative shall have a period of 20 days to resolve such dispute

their dispute by mutual agreement, the "Final Net Current Assets" shall be the
amounts agreed to by the parties.

their dispute within such 20 day period, upon demand of either Buyer or the
Holder Representative at any time during a 45 day period thereafter, the parties
shall refer such dispute to the Philadelphia, Pennsylvania office of
PricewaterhouseCoopers LLP who shall act as the Reviewing Accountant to review
the portions of the Actual Net Current Assets which are subject to dispute. The
parties shall, and shall instruct their respective accountants to, make
available to the Reviewing Accountant all work papers and all other information
and material in their possession as is requested by the Reviewing Accountant
that relates to the items of Actual Net Current Assets in dispute. The Reviewing
Accountant shall be instructed by the parties to use its best efforts to deliver
its determination to the parties as promptly as practicable after submission of
the dispute to the Reviewing Accountant. The determination of the Reviewing
Accountant shall be final and binding on the parties (absent manifest error);
and the Actual Net Current Assets reflected on the Closing Date Balance Sheet as
determined by the Holder Representative and as modified (if at all) by agreement
of Buyer and the Holder Representative or by the Reviewing Accountant in
accordance with this Section 2.03A. shall be the "Final Net Current Assets".

     Each party shall bear its own expenses and the fees and expenses of its own
representatives and experts, including its independent accountants, in
connection with the preparation, review, dispute (if any) and final
determination of the Final Net Current Assets. The parties shall share the
costs, expenses and fees of the Reviewing Accountant in inverse proportion to
the extent to which their respective' positions are sustained to a maximum of
100% for such party. For example, if the Holders assert that the dollar amount
of inventories, if any, should be $1,000,000 and Buyer asserts it should be
$800,000, and the Reviewing Accountant determines it to be $950,000, then the
Holder's position would have been 75% sustained (i.e., 75% of the $200,000 in
dispute was resolved in favor of the Holder's position) and the Holders would
bear 25% and the Buyer would bear 75% (i.e., an inverse proportion) of the
costs, expenses and fees of the Reviewing Accountant.

     Within ten days of the first to occur of (x) the expiration of the thirty
day period from the delivery by the Holder Representative to Buyer of the
Closing Date Balance Sheet and during which thirty day period Buyer does not
deliver the Dispute Notice to the Holder Representative hereunder; or (y) the
resolution by mutual agreement of Buyer and the Holder Representative of all
disputes regarding the Actual Net Current Assets; or (z) the delivery by the
Reviewing Accountant of its determination as to all portions of the Actual Net
Current Assets in dispute,

     if the Final Net Current Assets exceeds $13,016,000 (the "Final Positive
Adjustment"), then

     Buyer shall pay to the Holder Representative the amount by which the Final
Positive Adjustment exceeds $3,751,818 which amount shall be treated as an
adjustment to the Purchase Price, such amount to be paid 47% as a credit in
connection with the amounts paid to MEP Participants pursuant to Section0B.
hereof with the balance paid in cash within five (5) days after such
determination; and

- -5-



     the Holders shall pay to Buyer the amount by which $3,751,818 exceeds the
Final Positive Adjustment within five (5) days after such determination, which
amount shall be treated as an adjustment to the Purchase Price.

     if the Final Net Current Assets are less than $13,016,000, Holders shall
pay to Buyer an amount equal to the sum of (x) the amount of such shortfall,
plus (y) the amount of the Final Positive Adjustment, which amount shall be
treated as an adjustment to the Purchase Price.

Adjustments for Approved Capital Expenditures. Since the date of the Acquisition
Date Balance Sheet and prior to the date of execution of this Agreement, The
Hake Group of Companies have made certain capital expenditures, which aggregate
$650,000, that the Buyer has agreed shall be added to the Cash Amount as an
adjustment to the Purchase Price. Such capital expenditures for which Buyer has
agreed to increase the Cash Amount total $650,000 are set forth on Schedule
2.03B. hereto under the caption "Approved Capital Expenditure Amounts." The
Approved Capital Expenditure Amounts shall be paid by Buyer to the Holder
Representative for the benefit of the Holders at Closing. Such payment shall be
treated as an adjustment to the Purchase Price.

Adjustments to Deferred Portion of Purchase Price. Sections 12.02 and 12.03 of
this Agreement sets forth the terms and conditions upon which the Parties have
agreed to indemnify one another for certain breaches of representations,
warranties and covenants made in this Agreement. In the case of the Holders,
certain payments of indemnity are reflected as a decrease in the amount of the
Deferred Portion of the Purchase Price and therefore as an adjustment to the
Purchase Price.

MEP Payments.

At Closing, Hake Group, Inc. shall pay to the Holder Representative on behalf of
the participants (the "MEP Participants") of the Management Equity Plan (the
"MEP") the sum of $13,282,903 to be allocable to each participant in the pre-tax
withholding percentage shown opposite the MEP Participant's name on Exhibit D.

If a payment is due to the Holder Representative pursuant to Section 2.04A of
this Agreement, the amount otherwise due to the Holder Representative on behalf
of the Holders shall be reduced by forty-seven percent (47%) and the amount of
such reduction shall (subject to applicable withholding) be paid to the Holder
Representative for the benefit of the MEP Participants, in the pre-tax
withholding percentage set forth opposite the MEP Participant's name on Exhibit
D at the same time and in the same manner as the payment is made to the Holder
Representative under Section 2.04A.

Initial Fees. At Closing, the Hake Group, Inc. will pay to the entities
identified on Schedule 2.02A the Initial Fees in immediately available funds.

benefit or right under any Benefit Plan. The Hake Group of Companies has no
agreements with any employees for which the transactions contemplated by this
Agreement would cause additional payments, acceleration of benefits or any other

Intentionally Omitted.

Pension Plans. None of the Benefit Plans (other than Multi-employer Plans) is a
defined benefit plan or a money purchase plan subject to section 412 of the Code
or to Title IV of ERISA. There is no Liability, and there are no circumstances
which may arise which would give rise to any such Liability, of any member of
The Hake Group of Companies or Buyer of Matrix to the Pension Benefit Guaranty
Corporation ("PBGC") under Title IV of ERISA.

Compliance of Benefit Plans With ERISA and Code. Each member of The Hake Group
of Companies has performed all of its obligations under all Benefit Plans and
has made appropriate entries in its financial records and statements for all
Liabilities under all Benefit Plans that have accrued but are not due. All of
the Benefit Plans and any related trust agreements or annuity contracts (or any
funding instrument) comply currently, and have complied in the past, with the
provisions of ERISA and the Code, where required in order to be a qualified plan
under section 401(a) of the Code and tax exempt under section 501 of the Code,
and all other Legal Requirements, and any applicable collective bargaining
agreements. No event has occurred or circumstance exists that is reasonably
expected to give rise to disqualification or loss of tax exempt status of any
such Plan or trust, or result in any Tax, excise Tax, fines or penalties, or
amounts required to be paid under any settlement with the U.S. Department of
Labor, the IRS or the PBGC. Neither The Hake Group of Companies, nor any Person
who is a fiduciary or otherwise has a trust relationship with a Benefit Plan,
has any liability to the Benefit Plan, the IRS, the Department of Labor, or the
PBGC with respect to a Benefit Plan, or any Liability under sections 502(l) or
4071 of ERISA. All contributions and payments made or accrued with respect to
all Benefit Plans are deductible under the Code. No amount, or any asset of any
Benefit Plan, is subject to Tax as unrelated business taxable income. All
filings required by ERISA and the Code as to each Benefit Plan have been timely
filed, and all notices and disclosures to

- -17-



participants required by either ERISA or the Code have been timely provided.
Other than routine Claims for benefits submitted by participants or
beneficiaries in the ordinary course, no Claim against, or Proceeding involving
any Benefit Plan is pending or Threatened. No payment that is owed or may become
due to any director, officer, employee or agent of any member of The Hake Group
of Companies will be non-deductible to such member or subject to Tax under
sections 280G or 4999 of the Code, nor shall such member be required to
"gross-up" or otherwise compensate any such person because of the imposition of
any Tax or excise Tax on a payment to such person.

Multi-employer Plans. Neither The Hake Group of Companies nor an ERISA Affiliate
has received any notice from any Multi-Employer Plan that it is in
reorganization or is insolvent, that increased contributions may be required to
avoid a reduction in plan benefits or the imposition of any Tax, excise Tax, or
that such plan intends to terminate or has terminated. None of The Hake Group of
Companies nor an ERISA Affiliate has withdrawn from any Multi-Employer Plan with
respect to which there is any outstanding Liability as of the date hereof. No
event has occurred or circumstance exists that presents a risk of the occurrence
of any withdrawal from any Multi-Employer Plan that could result in any
Liability of any member of The Hake Group of Companies or Buyer or Matrix to a
Multi-Employer Plan.

Post-Retirement Benefits. Schedule 5.26 contains a calculation of the Liability
of each member of The Hake Group of Companies for post-retirement benefits for
its past and present officers, employees and directors (or their dependents or
beneficiaries) other than pensions, made in accordance with Financial Accounting
Statement 106 of the Financial Accounting Standards Board, regardless of whether
such member is required by such Statement to disclose such information. Except
as set forth on Schedule 5.26 or as required by section 601 et seq. of ERISA and
section 4980B of the Code, no member of The Hake Group of Companies provides, or
is obligated to provide, health or welfare benefits (including without
limitation, retiree medical insurance coverage or retiree life insurance
coverage) for any retired or former officer, employee or director, or any
dependents or beneficiaries of the same, nor is it obligated to provide any
health or welfare benefits to any active employee following such employee's
retirement or other termination of service. Each of The Hake Group of Companies
has the right to modify and terminate post-retirement benefits to retirees or
their dependents or beneficiaries (other than Pension Plan benefits) with
respect to both retired and active officers, employees and directors. To the
extent of such health or welfare benefits to retirees (or their dependents or
beneficiaries), Schedule 5.26 sets forth the name, medical insurance coverage,
and life insurance coverage for such retirees, dependents or beneficiaries.

Administration and Cost of Plans. Each of the Welfare Plans and Pension Plans
has been administered in material compliance with the requirements of the Code
and ERISA and all reports required by any governmental agency with respect to
each such Plan have been timely filed. No statement, either written or oral, has
been made by any of The Hake Group of Companies or an ERISA Affiliate to any
Person with regard to any Benefit Plan that was not in accordance with the
Benefit Plan and that could have an adverse economic consequence to The Hake
Group of Companies or Buyer or Matrix. Each Benefit Plan (other than Benefit
Plans subject to collective bargaining agreements), can be terminated within 30
days without payment of any additional contribution or amount and without the
vesting or acceleration of any benefits promised by such Plan. None of The Hake
Group of Companies nor an ERISA Affiliate has

- -18-



filed a notice of intent to terminate any current Plan or has adopted any
amendment to treat a Plan as terminated.

their respective directors, officers or employees who are fiduciaries, nor any
other fiduciary of any of the Pension Plans or Welfare Plans, has engaged in any
transaction in violation of section 406 of ERISA (for which no exemption exists
under section 408 of ERISA) or any "prohibited transaction" (as defined in

properly attributable to the next day, as anticipated in Treas. Reg. section
1.1504-76, provided, however, that any payments to MEP Participants after
Closing but before the 15th day of the 3rd calendar month after the month in
which Closing occurs shall be includable in the Final Tax Returns. No Section
338 election will be made with respect to the acquisition of the Hake Group of
Companies. Neither Matrix nor the Holders shall take any position inconsistent
with the preceding sentences on any Tax Return, except as otherwise required by
a final determination of the issue as defined in section 1313 of the Code.

In any case where Legal Requirements do not permit a member of The Hake Group of
Companies to close its taxable year on the Closing Date or in any case in which
a Tax is assessed with respect to a taxable period which includes the Closing
Date (but does not begin or end on that day), then Taxes, if any, attributable
to the taxable period of The Hake Group of Companies beginning before and ending
after the Closing Date shall be allocated (i) to the Holders for the period up
to and including the Closing Date (other than for items that occur after
Closing), and (ii) to Matrix for the period subsequent to the Closing Date . Any
allocation of income or deductions required to determine any income Taxes
attributable to any period beginning before and ending after the Closing Date
shall be made by means of a closing of the books and records of The Hake Group
of Companies as of the close of the Closing Date, provided that exemptions,
allowances or deductions that are calculated on an annual basis (including, but
not limited to, depreciation and amortization deductions) shall be allocated
between the period ending on the Closing Date and the period after the Closing
Date in proportion to the number of days in each such period. For Taxes imposed
on a daily basis, they shall be allocated based on the days in the period. The
foregoing allocation of responsibility for Taxes as between Matrix, on the one
hand, and the Holders, on the other hand, shall include without limitation, any
property Taxes assessed on or with respect to the assets or properties of The
Hake Group of Companies at any time prior to or following the Closing, and
attributable to any taxing period in which the Closing Date falls, whether or
not such Taxes are due and payable as of the Closing or in that taxing period.

Cooperation. The Holders and Matrix agree to furnish or cause to be furnished to
each other, and each at their own expense, as promptly as practicable, such
information (including access to books and records) and assistance, including
making employees available on a mutually convenient basis to provide additional
information and explanations of any material provided, relating to The Hake
Group of Companies as is reasonably necessary for the filing of any Tax Return,
for the preparation for any audit, and for the prosecution or defense of any
claim, suit or proceeding relating to any adjustment or proposed adjustment with
respect to Taxes. The Hake Group of Companies shall retain in its possession all
Tax Returns and Tax records relating to The Hake Group of Companies that are or
might reasonably be expected to become relevant to any computations or payments
required after the Closing Date with respect to Tax matters relating to any
taxable period (or portions thereof) ending on or prior to the Closing Date
until the relevant statute of limitations has expired, and shall afford the
Holders reasonable access to all such Tax Returns and Tax records, from
time-to-time, upon their request. After such time,

- -36-



Matrix may dispose of such materials, provided that prior to such disposition
Matrix shall give the Holders a reasonable opportunity to take possession of
such materials. Each of The Hake Group of Companies shall retain in their
possession, and shall provide the Holders reasonable access to (including the
right to make copies of), of such supporting Tax books and records relating to
The Hake Group of Companies that are or might reasonably be expected to become
relevant to computations or payments with respect to material Tax matters
relating to any taxable period (or portions thereof) ending on or before the
Closing Date, until the relevant statute of limitations has expired (or prior
thereto with the Holder Representative's consent).

Notices. Each of the Holders, Matrix and the members of Hake Group of Companies
shall promptly notify the others in writing of its receipt of notice of any
pending or Threatened federal, state, local or foreign Tax audits, assessments
or other dispute affecting the Tax reporting positions of The Hake Group of
Companies for taxable periods (or portions thereof) ending on or prior to the
Closing Date. For purposes of the foregoing sentence, the "others" as it applies
to the Holders shall refer to Matrix and the Holder Representative, and the
"others" as it applies to Matrix and the Hake Group of Companies shall refer to
the Holder Representative. The failure of a party to timely forward such
notification in accordance with the immediately preceding sentence shall not
relieve the other Party or its Affiliate of its obligation to pay such liability
for Taxes except and to the extent that the failure to timely forward such
notification actually prejudices the ability of the other Party or such
Affiliate to contest such liability for Taxes or increases the amount of such
Taxes.

Representation of Holders. The Holder Representative shall have the right to
represent the interests of The Hake Group of Companies in any Tax audit or
administrative or court proceeding relating to taxable periods ending on or
prior to the Closing Date and to employ counsel of its choice at its expense,
and Matrix shall have the right to consult with the Holder Representative during
such proceedings at its own expense. Matrix agrees that it shall cooperate
fully, and cause each member of The Hake Group of Companies to cooperate fully,
with the Holder Representative and its counsel in the defense against or
compromise of any claim in said proceeding, and the Holders agree to pay any
reasonable third party out of pocket expenses incurred by Matrix or The Hake
Group of Companies in connection therewith. Notwithstanding the foregoing, if
the results of such Tax audit or proceeding reasonably could be expected to have
a material adverse effect on the assets, business, operations, Tax position or
financial condition of Matrix, The Hake Group of Companies or any of their
Affiliates for taxable periods ending after the Closing Date, then there shall
be no settlement or closing or other agreement with respect thereto without the
written consent of Matrix which consent shall not be unreasonably withheld or
delayed.

Joint Representation. Matrix and the Holder Representative jointly shall
represent the interests of The Hake Group of Companies in any Tax audit or
administrative or court proceeding relating to any taxable period of The Hake
Group of Companies which includes (but does not begin or end on) the Closing
Date. Any disputes regarding the conduct or resolution of any such audit or
proceeding shall be resolved by arbitration as provided in Section0 The fees and
expenses of the arbitrator(s) shall be borne equally by Matrix and the Holders.
All other costs, fees and expenses paid to third parties in the course of such
audit or proceeding shall be borne by Matrix and the Holders in the same ratio
as the ratio in which, pursuant to the terms of this Agreement, Matrix and the
Holders would share the responsibility for payment of the Taxes asserted by the
taxing

- -37-



authority in such claim or assessment if such claim or assessment were sustained
in its entirety. Notwithstanding the foregoing, if the results of such Tax audit
or administrative or court proceeding could result in Holders being liable for
payments to Matrix under this Agreement, there shall be no settlement or closing
or other agreement with respect thereto without the written consent of the
Holder Representative, which shall not be unreasonably withheld or delayed.

Representation of Buyer. The Buyer shall have the right to represent the
interests of The Hake Group of Companies in any Tax audit or administrative or
court proceeding relating to taxable periods beginning after the Closing Date
and to employ counsel of its choice at its expense, and the Holder
Representative shall have the right to consult with Buyer during such
proceedings at its own expense. Buyer agrees that it shall cooperate fully, and
cause each member of The Hake Group of Companies to cooperate fully, with the
Holder Representative and its counsel in the defense against or compromise of
any claim in said proceeding, and Buyer agrees to pay any reasonable third party
out of pocket expenses incurred by the Holder Representative in connection
therewith. Notwithstanding the foregoing, if the results of such Tax audit or
proceeding reasonably could be expected to have a material adverse effect on the
assets, business, operations, Tax position or financial condition of the Holders
or any of their Affiliates for taxable periods ending after the Closing Date,
then there shall be no settlement or closing or other agreement with respect
thereto without the written consent of the Holder Representative (which consent
shall not be unreasonably withheld or delayed).

Refunds, Etc.

As additional Purchase Price, Matrix will deliver to the Holder Representative
all Tax refunds (including, without limitation, refunds arising by reason of
amended returns filed after the Closing Date) or credit of Taxes (plus any
interest thereon received with respect thereto from the applicable taxing
authority), other than those relating to state taxes attributable to the
carryforward of MEP Payments (the "MEP State Tax Refund"). Buyer shall pay to
the Holders all Tax refunds paid after the Closing Date, other than MEP State
Tax Refunds, with respect to (i) any period ending on or prior to the Closing
Date, or (ii) any period which includes the Closing Date but does not begin or
end on that day, provided that in the case of any Tax refund described in clause
(ii) of this Section0, the portion of such Tax refund that shall belong to the
Holders shall be that portion that is attributable to the portion of that period
which ends on the Closing Date (determined on the basis of an interim closing of
the books as of the Closing Date). Matrix will deliver such refunds within two
business days of receipt.

Matrix and the Holders agree to cooperate, and Matrix agrees to cause the Hake
Group of Companies and their Affiliates to cooperate with the Holders, after the
Closing Date, with respect to claiming any refund referred to in Section 7.16A.,
including notifying Matrix or the Holder Representative, as the case may be, of
the existence of any facts known to them that would constitute a reasonable
basis for claiming such a refund, providing all relevant information available
to and known to Matrix or the Holder Representative with respect to any such
claim, filing and diligently pursuing such claim, and in the case of the Party
filing such a claim, consulting with the other Party prior to agreeing to any
disposition of such claim.

Tax benefits in respect of Tax other than MEP Tax Refunds accruing to Matrix or
the Hake Group of Companies for periods that do not end on or prior to Closing
that are related to the MEP Payments are to be paid out to the Holder
Representative as additional Purchase Price, in accordance with the following
terms:

- -38-



     Matrix shall cause the Hake Group of Companies to (a) claim as a deduction
on its federal corporate income Tax Return from time to time when such deduction
may be utilized any payment to MEP Participants that is not included in a Final
Tax Return and (b) to carry forward and claim any net operating loss determined
in a Final Tax Return (the "NOL") that is available after application of
available carrybacks of such NOLs to years ending on or prior to Closing.

     Matrix will pay to the Holder Representative an amount equal to the
deduction claimed with respect to MEP Payment or in the NOL carry forward
claimed on the Tax Return, times the applicable statutory tax rate applicable to
the Tax Return on which the deduction or NOL carry forward is claimed. Payment
is to be made in cash within ten (10) days after the filing of the Tax Return.
Matrix will provide a statement detailing the amount of the deduction or NOL
carry forward claimed and the tax rate.

     The Holder Representative shall have a right to review any federal,
corporate Tax Return filed by Matrix or the Hake Group of Companies for periods
ending after Closing (but which include periods prior to Closing) for purposes
of reviewing the payments to be made pursuant to this Section0

     To the extent any deduction on a federal corporate income Tax Return
accruing to Matrix or the Hake Group of Companies for periods that do not end on
or prior to Closing, that are related to the MEP Payments and that were paid to
the Holder Representative pursuant to this Section0are later disallowed, the
Holder Representative shall refund to Matrix those amounts which the Holder
Representative had previously received and which relate to such disallowed
deduction.

     Matrix and the Hake Group of Companies shall be entitled to retain any
refunds or deductions for state and local Taxes for periods commencing after the
Closing Date arising out of net operating losses resulting in deductions related
to the MEP Payments.

Tax Indemnification.

The Holders, jointly and severally (except for the several only Holders
identified on Schedule 12.02B hereto), hereby agrees to indemnify, defend and
hold harmless the Buyer and Matrix from and against all Claims and all Losses
for all Taxes (whether legal liability for remittance of such Taxes is imposed
upon the Holders or a member of The Hake Group of Companies):

     With respect to any taxable year of any member of The Hake Group of
Companies which ends on or before the Closing Date (including but not limited to
any liability of The Hake Group of Companies pursuant to Treasury Regulation (S)
1.1502-6(a) or any comparable provision of state, local or foreign law) or is
assessed (whether before or after the Closing) as the result of a sale, exchange
or other disposition of property or assets which occurs prior to the Closing;

     With respect to any taxable year or period which includes but ends after
the Closing Date, to the extent attributable to the portion of such period which

Section 12.03, but shall be treated as adjustments to the Purchase Price by the
parties.

Buyer shall indemnify, defend and hold harmless the Holder Indemnitees (as
defined in Section0hereof) from and against all Claims and all Losses for all

any inquiries, offers or proposals from, discuss or negotiate with, provide any
non-public information to, or consider the merits of any unsolicited inquiries

and

refrain from undertaking any activity, or permitting any activity to be
undertaken, on the Leased Property which would result in a violation of any

- -42-



Buyer's and Matrix's Covenants Regarding Environmental Matters. Buyer and Matrix
covenant and agree that they shall:

promptly notify the Holder Representative and the Hake Group of Companies of and
provide them with copies of any documents relating to: (i) any governmental or
regulatory actions instituted or threatened under any Environmental Law in any

disposal of Hazardous Materials at the Talbot Property, (ii) all claims relating

Materials at the Talbot Property; and

fully cooperate with and grant to the Holder Representative and/or the Hake
Group of Companies and any of their agents or consultants access to the Talbot

required by any governmental entity or otherwise under this Agreement.

Investigation of The Hake Group of Companies by Buyer and Matrix. From the date
hereof through the Closing, the Holders shall cause The Hake Group of Companies
to afford to the officers, employees and authorized representatives of Buyer and
Matrix (including independent public accountants and attorneys and other third
party consultants) reasonable access to the offices, properties, employees and
business and financial records (including computer files, retrieval programs and
similar documentation and such access and information that may be necessary in
connection with an environmental audit) of The Hake Group of Companies to the
extent Buyer or Matrix shall deem reasonably necessary or desirable, and shall
furnish to Buyer and Matrix or their authorized representatives such additional
information concerning the assets, properties and operations of The Hake Group
of Companies as shall be reasonably requested, including all such information as
shall be reasonably necessary or appropriate to enable Buyer and Matrix or their
representatives to verify the accuracy of the representations and warranties
contained in this Agreement, to verify that the covenants of the Holders and of
The Hake Group of Companies contained in this Agreement have been complied with,
and to determine whether the conditions set forth in Section0have been
satisfied. Buyer and Matrix agree that such investigation shall be conducted in
such a manner as will not interfere unreasonably with the operations of The Hake
Group of Companies and that such investigation shall be at Buyer's sole cost and
expense. No investigation made by Buyer, Matrix or their representatives
hereunder shall affect the representations and warranties of the Holders made in
this Agreement.

Remedy for Breach of Sections 8.01 and 8.03. The parties acknowledge and agree
that, because of the nature and subject matter of the provisions of Section 8.01
and Section 8.03 it would be impractical and extremely difficult to determine
actual damages in the event of the breach of any such provisions. Accordingly,
if the Holders and any of its Affiliates (including The Hake Group of Companies
prior to the Closing), on the one hand, or Buyer and any of its Affiliates
(including Matrix), on the other hand, commits a breach, or threatens to commit
a breach, of any matter set forth in Sections 8.01 and 8.03, the non-breaching
party shall have the right to have the provisions of Section 8.01 or 8.03, as
the case may be, specifically enforced by any court having equity jurisdiction,
it being further acknowledged and agreed by the parties that any such breach or
threatened breach will cause irreparable injury to the non-breaching party and
its Affiliates and that an injunction may be issued against the breaching party
to stop or prevent

- -43-



such breach or threatened breach. If any such action shall be instituted, the
breaching party agrees to waive, and does hereby waive to the fullest extent
permitted by law, the defense that the non-breaching party has an adequate
remedy at law and agrees to interpose no opposition, legal or otherwise, as to
the propriety of pursuing specific performance as a remedy and agrees not to
request any bonding for the issuance of the relief sought.

Title Insurance; Surveys. The Hake Group of Companies has obtained, at Buyer's
expense, and delivered to Buyer, a commitment to issue the insurance on the
Talbot Property at the Closing:

Commitment. With respect to the Talbot Property, a commitment to issue an ALTA
Owner's Policy of Title Insurance (Form 10/17/92 or its nearest equivalent if
the Talbot Property is located in a jurisdiction in which Form 10/17/92 is not
available) (the "Commitment"), which Commitment shall be issued by a title
insurer reasonably satisfactory to Buyer, committing to insure the interest of
the applicable member of The Hake Group of Companies in such Talbot Property for
$325,000 (including in all improvements).

Further Commitment Requirements. In addition to the matters set forth in A. and
B. above, the Commitment shall further commit:

     to insure title to all recorded easements benefiting the Talbot Property;

     to issue an ALTA Endorsement 3.1 (or equivalent) as to the Talbot Property;
     and

     to issue a standard "non-imputation" endorsement.

Surveys. With respect to the Talbot Property, Buyer has ordered, at its expense,
a survey by a licensed surveyor, certified to Matrix and to the title company
insuring the Talbot Property and conforming to the Minimum Detail Requirements
for ALTA/ACSM Land Surveys (Class A Survey) including all items contained in
items1.1, 2, 3, 4, 6, 8, and 10 (the "Survey").

Title at Closing. At the Closing, the state of title to the Talbot Property
shall be such that the title company issuing the Commitment for that Property
shall be prepared to and shall issue a title policy on the form mandated herein,
insuring the interest of the applicable member of The Hake Group of Companies
owning such Property as a valid fee simple interest, (i) subject only to the
Permitted Exceptions, (ii) having deleted therefrom the standard exceptions for
parties in possession, survey, rights of way and easements not of record and
mechanics and materialman's liens (iii) insuring that the Property as described
in the policy is the same property as is described in the Survey for the Talbot
Property, (iv) insuring the contiguity of the Property if the Property consists
of more than one tract or lot and (v) insuring direct and unencumbered
pedestrian and vehicular access to the Talbot Property from each street or
roadway adjacent to the Property.

Lien and Litigation Searches. Buyer and Matrix may (in their discretion) obtain,
at their cost and expense, a Uniform Commercial Code security interest search
report, a tax lien search report and a litigation search report, showing that
there are no Encumbrances against the assets, properties or rights of The Hake
Group of Companies, other than those disclosed on Schedule0and no litigation,
except as disclosed on Schedule0.

Transition of The Hake Group of Companies. From and after the Closing, the
Holders covenant and agree with Buyer and Matrix to cause The Hake Group of
Companies to cooperate with Buyer and Matrix to effect the smooth transition of
the control and operation of The Hake Group

- -44-



of Companies from the Holders to Buyer, as contemplated herein, including the
retention of the customers of The Hake Group of Companies, by such means that
Matrix may reasonably request at Matrix's sole cost and expense.

Further Assurances. Each of the Parties hereto shall, at any time, and from time
to time, at or after the Closing Date, upon the request of the appropriate
Party, do, execute, acknowledge and deliver, or will cause to be done, executed,
acknowledged and delivered, all such further acts, assignments, transfers,
conveyances, and assurances as may be reasonably required to complete the
transactions contemplated in this Agreement. After the Closing Date the Holders
shall, and shall use their reasonable best efforts to assure that any necessary
third party shall, execute such documents and do such other acts and things as
Buyer or Matrix may reasonably require for the purpose of giving to Buyer and
Matrix (and The Hake Group of Companies after the Closing) the full benefit of
all the provisions of this Agreement and as may be reasonably required to
complete the transactions contemplated in this Agreement.

No Actions Constituting a Breach. From the date hereof through the Closing Date,
no Holder will, and the Holders agree to cause each member of The Hake Group of
Companies not to, take or knowingly permit to be done anything in the conduct of
the business of The Hake Group of Companies which would be a misrepresentation,
breach of warranty or non-fulfillment of any covenant or agreement on the part
of that Party under this Agreement, and each of the Parties hereto shall cause
the deliveries for which such Party is responsible at the Closing to be duly and
timely made.

Notification of Breaches. From the date hereof through the Closing Date, each
Party agrees to promptly notify the other Parties in writing if such Party
becomes aware of the occurrence after the date of this Agreement of any fact or
condition that would (except as expressly contemplated by this Agreement) cause
or constitute a breach by that Party of any of its representations or warranties
as of the date of this Agreement had its representations and warranties been
made as of the time of the occurrence or discovery of such fact or condition.
Should any such fact or condition require any change in the Schedules if the
Schedules were dated the date of the occurrence or discovery of any such fact or
condition, Buyer and the Holder Representative will promptly deliver to one
another a mutually agreeable supplement to the Schedules specifying such change.
During the same period, each Party agrees to promptly notify the other parties
of the occurrence of any breach of any covenant of that Party in this Agreement
or of the occurrence after the date of this Agreement of any event that may make
the satisfaction of the conditions in 0 impossible or unlikely. Provided that
the Closing occurs, any disclosure by any Party pursuant to this Section0,
including any supplement of the Schedules by Buyer and the Holder Representative
as contemplated above, shall be deemed to amend or supplement the Schedules for
purposes of preventing or curing any misrepresentation or breach of a warranty.
Notwithstanding the foregoing, such disclosure shall not be deemed to amend the
Schedules for purposes of the conditions to Closing provided in Section 9.01A.

Compliance With Conditions. Each Party hereto agrees to cooperate fully with the
other Parties, and shall use its reasonable best efforts to cause the conditions
precedent for which such Party is responsible to be fulfilled. Each Party hereto
further agrees to use its reasonable best efforts, and act in good faith, to
consummate this Agreement and the transactions contemplated herein as promptly
as possible.

- -45-

steps that are within their power to cause to be fulfilled those of the
conditions precedent to each Party's obligations to consummate the transactions
contemplated herein as are dependent upon their actions; and (ii) use their
reasonable best efforts to take, or cause to be taken, all action and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws to consummate and make effective the transactions contemplated hereby and
not to take any actions that would be inimical to such result. The Buyer,
Matrix, the Holders and The Hake Group of Companies have prepared and filed with
the United States Department of Justice and the Federal Trade Commission the
notification and report form with respect to the transactions contemplated in
this Agreement as required pursuant to the HSR Act and have obtained early
termination of the waiting period under the HSR Act. Each Party shall further
pay its own costs in connection with such filing and any filing fees shall be
paid jointly by the Parties

Guaranties.

Matrix hereby guarantees unconditionally and absolutely to the Holders the due
and punctual payment and performance by Buyer of all obligations of Buyer
provided for in this Agreement that are to be paid or performed by Buyer. The
obligations of Matrix hereunder shall remain in full force and effect without
regard to, and shall not be affected or impaired by, any of the following, any
of which may be taken without the consent of, or notice to, Matrix:

     Any exercise, non-exercise or waiver by Buyer of any right or privilege
under this Agreement (provided, that any non-performance by the Holders that
would be a defense to Matrix's performance under this Agreement shall constitute
a defense to Matrix under this Section 0)

     Any bankruptcy, insolvency, reorganization, dissolution, liquidation or
other like proceeding relating to any Holder or any member of The Hake Group of

shall defend, indemnify and hold the Holders, and their respective directors,
officers, shareholders, Affiliates, successors and assigns (collectively, the
"Holder Indemnitees"), harmless from and against, and will pay to the Holder
Indemnitees the amount of, all Damages suffered or incurred by them (or any of
them) resulting from, arising directly or indirectly out of or in connection
with (without duplication):

Any misrepresentation or breach of warranty made by Buyer or Matrix in this
Agreement or in any Ancillary Document to which it is a party.

Any breach by Buyer or Matrix of any covenant, agreement or obligation of Buyer
or Matrix in this Agreement or in any Ancillary Document to which it is a party.

Procedure for Indemnification.

Notice of Claims. Promptly after receipt by a Party (the "Claiming Party") of
notice of the commencement or assertion of any claim, action, suit, Proceeding,
arbitration, audit, hearing, investigation, Order or litigation (each a "Claim")
against it or any Holder Indemnitee (in the case of the Holders) or any Matrix
Indemnitee (in the case of Buyer, Matrix and The Hake Group of Companies), and
if a claim is to be made by the Claiming Party against any other Party (the
"Indemnifying Party") for indemnification with respect to that Claim pursuant to
Section 12.02 or 12.05 (as applicable), the Claiming Party shall promptly give
notice to the Indemnifying Party of the commencement or assertion of such Claim;
provided, that the failure to so notify the Indemnifying Party of the
commencement or assertion of such Claim will not relieve the Indemnifying Party
of any liability that it may have to any Matrix Indemnitee or Holder Indemnitee
(as applicable) hereunder, except to the extent that such Indemnifying Party
demonstrates that the defense of such action was prejudiced by the Claiming
Party's failure to give such notice. The notice contemplated herein shall
describe the Claim and the specific facts and circumstances in reasonable
detail, shall include a copy of any related notices or written claims

- -58-



from third-parties, and shall indicate the amount, if known, or an estimate, if
possible, of the Damages that have been or may be suffered or incurred.

Assumption of Defense. If any Claim is brought against a Matrix Indemnitee or a
Holder Indemnitee and the Claiming Party gives notice to the Indemnifying Party
of such Claim, the Indemnifying Party will, unless the Claim involves Taxes
(which shall be resolved in accordance with the procedures in 0), be entitled to
participate in such Claim and, to the extent that it wishes (unless (i) such
Indemnifying Party is also a party to such Claim and the Claiming Party
determines in good faith that joint representation would be inappropriate, or
(ii) the Indemnifying Party fails to provide reasonable assurance to the
Claiming Party of its financial capacity to defend such Claim and provide
indemnification with respect to such Claim), to assume the defense of such Claim
with counsel reasonably satisfactory to the Claiming Party and, after notice
from the Indemnifying Party to the Claiming Party of its election to assume the
defense of such Claim, the Indemnifying Party will not, as long as it diligently
conducts such defense, be liable to the Claiming Party or the other relevant
Holder Indemnitee(s) or Matrix Indemnitee(s) (as applicable) under this
Section0for any fees of other counsel or any other expenses with respect to the
defense of such Claim, in each case subsequently incurred by the Claiming Party
or the other relevant Holder Indemnitee(s) or Matrix Indemnitee(s) (as
applicable) in connection with the defense of such Claim, other than their
reasonable costs of investigation. If the Indemnifying Party assumes the defense
of a Claim, (i) it will be conclusively established for purposes of this
Agreement that the Claim (and any resulting Damages) are within the scope of and
subject to indemnification by the Indemnifying Party; (ii) no compromise or
settlement of such claims may be effected by the Indemnifying Party without the
Claiming Party's consent unless (A) there is no finding or admission of any
violation of Legal Requirements or any violation of the rights of any Person and
no effect on any other Claims that may be made against the Claiming Party or any
other Holder Indemnitee or Matrix Indemnitee (as applicable), and (B) the sole
relief provided is monetary damages that are paid in full by the Indemnifying
Party; and (iii) the Claiming Party and each relevant Holder Indemnitee or
Matrix Indemnitee (as applicable) will have no liability with respect to any
compromise or settlement of such Claims effected without its consent. The
Claiming Party and any relevant Holder Indemnitee or Matrix Indemnitee shall be
entitled to participate (at its expense) in the defense of any Claim assumed by
the Indemnifying Party as contemplated herein. If notice is given to an
Indemnifying Party of any Claim and the Indemnifying Party does not, within ten
days after the Claiming Party's notice is given, give notice to the Claiming
Party of its election to assume the defense of such Claim, the Indemnifying
Party will no longer have the right to assume that defense, and will be bound by
any determination made in such Claim or any compromise or settlement effected by
the Claiming Party or any other Holder Indemnitee or Matrix Indemnitee (as
applicable).

Exception. Notwithstanding the foregoing, if a Claiming Party or any other
Holder Indemnitee or Matrix Indemnitee (as applicable), determines in good faith
that there is a reasonable probability a Claim (other than a claim arising under
Section 12.02(c) hereof) may adversely affect it or its Affiliates other than as
a result of monetary damages for which it would be entitled to indemnification
under this Agreement, that party or Person may, by notice to the Indemnifying
Party, assume the exclusive right to defend, compromise or settle such Claim,
but the Indemnifying Party will not be bound by any determination of a Claim so
defended or any compromise or settlement effected without its consent (which may
not be unreasonably withheld).

Other Claims. A claim for indemnification for any matter not involving a
third-party Claim may be asserted by notice to the Party from whom
indemnification is sought.

Cooperation of Parties. The Party assuming the defense of any Claim shall keep
the other Party(s) reasonably informed at all times of the progress and
development of the Party's defense of and

- -59-



compromise efforts with respect to such Claim, and shall furnish the other
Party(s) with copies of all relevant pleadings, correspondence and other papers.
In addition, the Parties to this Agreement shall cooperate with each other, and
make available to each other and their representatives all available relevant
records or other materials required by them for their use in defending,
compromising or contesting any Claim.

No Liability of The Hake Group of Companies. In the event a Claim is made
against the Holders for any Damages incurred by Buyer or Matrix, the Holders
shall not, nor shall they be entitled to, maintain, assert or make a claim
against any member of The Hake Group of Companies, or the directors or officers
of each, for contribution, indemnity or any other recovery, it being the
intention of the Parties hereto that after the Closing The Hake Group of
Companies shall have no liability, obligation or responsibility to the Holders
for any breach or nonfulfillment of the representations, warranties, covenants
or obligations of Buyer and Matrix made in this Agreement.

Arbitration.

Referral. If any dispute under this Agreement or any Ancillary Document arises
and the relevant Parties are unable to resolve such dispute, the unresolved
dispute shall be resolved by arbitration if a Party requests arbitration in
accordance with this Section 0. The place of arbitration shall be in
Philadelphia, Pennsylvania. Arbitration shall be conducted under the auspices of
the American Arbitration Association ("AAA"). Except as otherwise provided in
this Section 0, the Rules of the AAA shall govern all proceedings; and in the
case of conflict between the AAA Rules and this Agreement, the provisions of
this Agreement shall govern.

Demand. Any Party may initiate arbitration by making a demand on the other
relevant Party(s) and simultaneously filing copies of the demand, together with
the required fees, with the AAA office in Philadelphia, Pennsylvania. The demand
shall contain those provisions required by the Rules of the AAA and shall also
request the AAA to designate and appoint one person as the arbitrator, who shall
act as the sole arbitrator to resolve the matter.

Discovery. The Parties shall have the right of discovery in accordance with the
Federal Rules of Civil Procedure except that discovery may commence immediately
upon the service of the demand for arbitration. A Party's unreasonable refusal
to cooperate in discovery shall be deemed to be refusal to proceed with
arbitration and, until AAA has designated the arbitrator, the Parties may
enforce their rights (including the right of discovery) in the courts. Such
enforcement in the courts shall not constitute a waiver of a Party's right to
arbitration. Upon his or her appointment, the arbitrator shall have the power to
enforce the Parties' discovery rights.

Binding Decision. The Parties shall be bound by the decision of the arbitrator
and accept his or her decision as the final determination of the matter in
dispute. The prevailing Party(s) shall be entitled to enter a judgment in any
court upon any arbitration award made pursuant to this Section 0 The arbitrator
shall award the costs and expenses of the arbitration, including reasonable
attorneys' fees, disbursements, arbitration expenses, arbitrators' fees and the
administrative fee of the AAA, to the prevailing Party as shall be determined by
the arbitrator. The dispute resolution procedure set forth in this Section 12.07
shall be the sole procedure by which disputes between the Parties under this
Agreement or any Ancillary Document shall be resolved.

Claims Against Deferred Portion of the Purchase Price. If at any time or times
prior to the expiration date of Buyer's right to make a Claim for Damages
against the Holders pursuant to Article XII of this Agreement, Buyer makes a
Claim (a "Notice of Claim") that, pursuant to the terms of this Agreement, would
reduce the Deferred Portion of the Purchase Price, Buyer shall give notice
thereof to the Holder Representative in accordance with the procedures of
Section 12.07 of

- -60-



this Agreement. If the Holder Representative dispute such Claim, the Holder
Representative must give written notice thereof (the "Claim Dispute Notice"), to
Buyer within fifteen (15) days after the date of Buyer's Notice of Claim, in
which case the Buyer shall delay making any permanent reduction in the Deferred
Portion of the Purchase Price until such time as the Claim is resolved by the
mutual agreement of the Parties or by arbitration pursuant to Section 12.08
hereof; provided however, any scheduled payments that become due and payable
from the Deferred Portion of the Purchase Price as provided in Section 2.02B.
hereof shall be reduced by the amount of such Claim until such Claim is resolved
as provided above. If the Holder Representative fails to deliver a Claim Dispute
Notice within such fifteen (15) day period, such Claim shall be deemed to have
been acknowledged and accepted by the Holders and the Deferred Portion of the
Purchase Price shall be permanently reduced by the full amount as set forth in
the Claim and shall be applied to the reduce the first maturing payment due of
the Deferred Portion of the Purchase Price. In the event that the amount subject
to the Claim is unliquidated, Buyer shall have made a good faith estimate as to
the amount of the Claim that is included in the Notice of Claim.

Payment Procedures. In the event any payment required to be made by any party
(the "Defaulting Party") hereto is not made when due (a "Payment Default") the
party to whom such payment was to be made (the "Non-defaulting Party") shall be
entitled to recover from the Defaulting Party interest on the amounts not paid
at the Default Rate from the date such Payment Default occurred until the date
such Payment Default (together with all interest and Collection Expenses payable
in conjunction therewith) is paid in full. In addition, the Non-defaulting Party
shall be entitled to recover from the Defaulting Party all costs and expenses of
collection (including reasonable attorneys' fees) incurred in connection with
such Payment Default (the "Collection Expenses"). In the event that any portion
of the Deferred Portion of the Purchase Price (a "Deferred Portion") is not paid
on the date scheduled for payment of such amounts (the "Scheduled Date") by
reason of any unresolved claim for indemnification hereunder (an "Unresolved
Indemnity Claim"), if upon resolution of such Unresolved Indemnity Claim, the
Holders shall be entitled to receive any portion of the Deferred Portion, the
Holders shall also be entitled to be paid by Matrix, interest at the Withholding
Rate from the Scheduled Date until the date on which payment is received,
pursuant to this Section0 For purposes of this Agreement, "Default Rate" means
the interest rate in effect from time to time on the Matrix Revolving Credit
Loan plus three percent (3%) and "Withholding Rate" means the interest rate in
effect from time to time on the Matrix Revolving Credit Loan.

                            MISCELLANEOUS PROVISIONS

Confidentiality of Agreement. Each Party agrees that it will treat in confidence
all Confidential Information which such Party shall have obtained regarding the
other Parties during the course of the negotiations leading to the consummation

after the date hereof), the investigation provided for herein and the
preparation of this Agreement and the Ancillary Documents, and in the event the
transactions contemplated in this Agreement shall not be consummated, each Party
will return to the other Parties all copies of Confidential Information which

Information included in the assets, properties or

- -61-



rights of The Hake Group of Companies, or otherwise reasonably related to The
Hake Group of Companies or their assets, properties or rights. The obligation of
each Party to treat such documents, materials and other information in

the foregoing, the terms of the Confidentiality Agreement between Matrix and The
Hake Group, Inc. dated as of September 9, 2002 shall continue to be binding upon
the Parties in accordance with its terms, regardless of any termination of this
Agreement, until and unless the Closing shall occur.

submits to personal jurisdiction in the Commonwealth of Pennsylvania and in the
courts in such state located in Delaware County and the United States District

or relating to this Agreement which is not subject to arbitration as provided in
Section 11, and agrees that all claims in respect of the Proceeding may be heard
and determined in any such court. Each of the Parties hereto further consents

the Eastern District of Pennsylvania and the Courts of the Commonwealth of
Pennsylvania located in Delaware County. Each Party agrees that a final judgment

or in any other manner provided by law or in equity, in any court or other
tribunal having competent jurisdiction.

Construction. The Parties have participated jointly in the negotiation and
drafting of this Agreement. In the event an ambiguity or question of intent or
interpretation arises, this Agreement shall be construed as if drafted jointly

disfavoring any Party by virtue of the authorship of any of the provisions of

refer to all rules and regulations promulgated thereunder, unless the context
requires otherwise. In the event of any inconsistency between the statements in

representation, warranty, covenant and obligation contained herein shall have
independent significance. If any Party has breached any representation,
warranty, covenant or obligation contained herein in any respect, the fact that
there exists another representation, warranty, covenant or obligation 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, covenant or
obligation. Unless the context clearly states otherwise, the use of the singular
or plural in this Agreement shall include the other and the use of any gender

- -62-



shall include all others. All references to "Section" or "Sections" refer to the

relating to the subject matter hereof. This Agreement may be amended, modified,
superseded, or canceled only by a written instrument signed by all of the
Parties hereto, and any of the terms, provisions, and conditions hereof may be
waived only by a written instrument signed by the waiving Party.

deemed to include material included in any other Schedule, unless the Schedule
specifically states that the material is to be included in another specified
Schedule.

that might require the application of the laws of another jurisdiction.

Headings. The headings in this Agreement are included for purposes of
convenience only and shall not be considered a part of this Agreement in
construing or interpreting any provision hereof.

Invalidity of Provisions; Severability. If any provision of this Agreement or
the application thereof to any Person or circumstance shall to any extent be
held in any Proceeding to be invalid, illegal or unenforceable, the remainder of
this Agreement, or the application of such provision to persons or circumstances
other than those to which it was held to be invalid, illegal or unenforceable,
shall not be affected thereby, and shall be valid, legal and enforceable to the
fullest extent permitted by law, but only if and to the extent such enforcement
would not materially and adversely frustrate the parties' essential objectives
as expressed herein. Notwithstanding the foregoing, each Party hereto agrees
that it has reviewed the provisions of this Agreement, and that the same, taken
as a whole, are fair and reasonable. The Parties hereto shall endeavor in good
faith negotiations to replace the invalid, illegal or unenforceable provisions
with valid provisions, the economic effect of which comes as close as possible
to that of the invalid, illegal or unenforceable provisions.

Successors and Assigns.

Assignment. The rights of any Party under this Agreement shall not be assignable
by such Party hereto prior to the Closing without the consent of the other
Parties, except that the rights of Buyer hereunder may be assigned prior to the
Closing, without the consent of the Holders, to any corporation all of the
outstanding capital stock of which is owned or controlled by Matrix, or to any
general or limited partnership, or limited liability company or partnership, in
which Matrix or any such corporation is a general partner or controlling member;
provided that

     such assignment shall not result in the Holders or The Hake Group of
Companies having to amend its respective Notification and Report Form filed
under the HSR Act in connection with the transactions contemplated herein,

     the assignee shall assume in writing all of such Party's obligations
hereunder,

     the Holders and Matrix shall not be released from any of its obligations

signed by the other Parties, (b) no waiver that may be given by a Party will be
applicable except in the specific instance for which it is given, and (c) no
notice to or demand on one Party will be deemed to be a waiver of any obligation

                                   APPENDIX I

                              CERTAIN DEFINED TERMS

     As used in the Equity Interests Purchase Agreement dated as of March 7,
2003, among the Holders, Buyer and Matrix, the following capitalized terms shall
have the meanings set forth below. References hereto to particular Sections
shall refer to Sections of the Equity Interests Purchase Agreement, unless the
context clearly requires a different construction.

     "Accounts Receivable" shall mean, without duplication, the amount owing by
a debtor created in the ordinary course of business and arising from the bona
fide performance of services or the sale or lease of goods and such amount is
shown on the balance sheet as an Accounts Receivable in accordance with GAAP.

Section 0.

     "Affiliate" shall mean any Person that, directly or indirectly, through one
or more intermediaries, controls or is controlled by, or is under common control
with, the Person specified. For purposes of this definition, "control" means the
