          (m)  all Liabilities relating to Buyer's ownership or use of

          (b)  any Liability of Seller for Taxes, including, but not

Buyer, and to place Buyer in possession and control of, the
Assets, or to enable Buyer to exercise and enjoy all rights and
benefits of Seller with respect thereto (including, without
limitation, a trademark assignment agreement in a form reasonably
acceptable to Buyer and Seller).  Buyer shall take such actions
as Seller may reasonably request in order to assure Buyer's
assumption of the Assumed Liabilities.

Swaine & Moore, Worldwide Plaza, 825 Eighth Avenue, New York, New
York 10019 on the third Business Day after satisfaction or waiver

Closing, but subject to the satisfaction or waiver of those
conditions), or at such other date or at such other place or time
as the parties may mutually agree upon, but in any event not
later than October 18, 2002 (if this Agreement is terminated in
accordance with Section 10.1(d)) (such date of the Closing is
hereinafter referred to as the "Closing Date").  The Closing will

   3.2.  Payment of Purchase Price; Instruments of Conveyance

          (a)  At the Closing, Buyer shall (i) deliver to Seller the
Purchase Price, and (ii) execute and deliver to Seller the
Assignment and Assumption Agreement and Bill of Sale, the
Assignment of Patents, the Maryland Landlord's Estoppel
Certificate, the Texas Landlord's Consent to Assignment and

           (b)  At the Closing, Seller shall execute and deliver to

the Assignment of Patents, the Maryland Landlord's Estoppel
Certificate, the Texas Landlord's Consent to Assignment and
Estoppel Certificate and the Deed of Conveyance.
                                
                           ARTICLE IV
                                
                         PURCHASE PRICE
                                
   4.1.  Purchase Price.  The purchase price for the Assets (the 
"Purchase Price") is One Hundred Forty-Six Million Dollars ($146,000,000),
subject to adjustment as provided in Section 4.2, payable in cash
by wire transfer of immediately available funds at the Closing to
a bank account designated by Seller.

   4.2.  Purchase Price Adjustment.

          (a)  Within sixty (60) Business Days after the Closing Date,
Buyer shall prepare and deliver to Seller a statement of the
Assets and the Assumed Liabilities as of the close of business on
the Closing Date (such statement, the "Closing Statement of
Assets and Liabilities").  Seller shall cooperate with Buyer in
connection with, and shall furnish to Buyer all such information
as Buyer may reasonably require, in the preparation of the
Closing Statement of Assets and Liabilities; provided, however,
that Seller acknowledges that Buyer shall have the primary
responsibility and authority for preparing the Closing Statement
of Assets and Liabilities.  The Closing Statement of Assets and
Liabilities will be prepared (i) using the same accounting
methods, standards, policies, practices, classifications,
estimation methodologies, assumptions, procedures and level of
prudence as were used to prepare the Financial Statements, and
(ii) on the basis of facts existing and events occurring on or
before the Closing Date only; provided, however, that the Closing
Statement of Assets and Liabilities shall exclude Taxes.  In the
event that the Closing Date does not occur at a financial week or
month end for accounting purposes, the parties shall agree on
mutually acceptable roll forward or roll back procedures.

          (b)  The parties hereto agree that the procedure set forth
herein with respect to the Closing Statement of Assets and
Liabilities, and the purchase price adjustment provided herein,
are not intended to permit the introduction of different
accounting methods, standards, policies, practices,
classifications, estimation methodologies, assumptions,
procedures or a different level of prudence for purposes of
determining the asset and liability balances from those used to
prepare the Financial Statements.  The adjustment contemplated by
this Section 4.2 is intended to show the change in Closing Net
Assets from the date of the Balance Sheet to the Closing Date,
and such change can only be measured if the calculation is done
the same way, using the same methods, for both dates.
Accordingly, and without limiting the generality of the
foregoing, the calculation of Closing Net Assets shall not
include any change in the net difference between the value of the
Assets and the Assumed Liabilities that arises because of a re-
assessment of the value of Assets or Assumed Liabilities at June
28, 2002, or any change in the net difference between the value
of the Assets and the Assumed Liabilities that does not arise as
a result of an event occurring after June 28, 2002.  Following
the Closing, Buyer shall not take any actions with respect to the
accounting books and records of the Business on which the Closing
Statement of Assets and Liabilities is to be based that are not
consistent with the Business's past practices.  Without limiting
the generality of the foregoing, no changes shall be made in any
reserve or other account existing as of the date of the Balance
Sheet except as a result of events occurring after the date of
the Balance Sheet and, in such event, only in a manner consistent
with past practices.

          (c)  Each party shall provide the other party and its
representatives with reasonable access to books and records and
relevant personnel during the preparation of the Closing
Statement of Assets and Liabilities and the resolution of any
disputes that may arise under this Section 4.2.

          (d)  If Seller disagrees with the determination of the
Closing Net Assets as shown on the Closing Statement of Assets
and Liabilities, Seller shall notify Buyer in writing of such
disagreement within forty-five (45) days after delivery of the
Closing Statement of Assets and Liabilities, which notice shall
describe the nature of any such disagreement in reasonable
detail, identify the specific items involved and the dollar
amount of each such disagreement and provide reasonable
supporting documentation for each such disagreement.  Subject to
compliance by Buyer with the next sentence, after the end of such
forty-five (45) day period, Seller may not introduce additional
disagreements with respect to any item in the Closing Statement
of Assets and Liabilities or increase the amount of any
disagreement, and any item not so identified shall be deemed to
be agreed to by Seller and will be final and binding upon the
parties.  During the forty-five (45) day period of its review,
Seller shall have reasonable access to any documents, schedules
or workpapers, including those of independent auditors or other
agents, used in the preparation of the Closing Statement of
Assets and Liabilities, to the personnel who prepared the Closing
Statement of Assets and Liabilities and to other employees of or
advisors to Buyer or the Business to the extent access is
reasonably required for Seller to assess the acceptability of the
Closing Statement of Assets and Liabilities.

          (e)  Buyer and Seller agree to negotiate in good faith to
resolve any disagreement with respect to the Closing Statement of
Assets and Liabilities.  If Buyer and Seller are unable to
resolve all disagreements properly identified by Seller pursuant
to Section 4.2(d) within thirty (30) Business Days after delivery
to Buyer of written notice of such disagreement, then such
disagreements shall be submitted for final and binding resolution
to a Neutral Accounting Firm to resolve such disagreements (the
"Accounting Arbitrator").  The Accounting Arbitrator shall be a
Neutral Accounting Firm selected by mutual agreement of Buyer and
Seller; provided that (i) if the parties are unable to agree on a
Neutral Accounting Firm to act as Accounting Arbitrator, each
party shall select a Neutral Accounting Firm and such firms
together shall select the Neutral Accounting Firm to act as the
Accounting Arbitrator, and (ii) if any party does not select a
Neutral Accounting Firm within ten (10) days of written demand
therefor by the other party, the Neutral Accounting Firm selected
by the other party shall act as the Accounting Arbitrator.  The
Accounting Arbitrator will only consider those items and amounts
set forth in the Closing Statement of Assets and Liabilities as
to which Buyer and Seller have disagreed within the time periods
and on the terms specified above and must resolve the matter in
accordance with the terms and provisions of the Agreement and
shall deliver to Buyer and Seller, as promptly as practicable and
in any event within 60 Business Days after its appointment, a
written report setting forth the resolution of any such
disagreement determined in accordance with the terms of this
Agreement.  The scope of the disputes to be resolved by the
Accounting Arbitrator shall be limited to whether such
calculation was done in accordance with the accounting methods,
standards, policies, practices, classifications, estimation
methodologies, assumptions, procedures or level of prudence used
to prepare the Financial Statements, and whether there were
mathematical errors in the calculation of the Closing Net Assets,
and the Accounting Arbitrator is not to make any other
determination, including any determination as to whether GAAP was
followed for the Balance Sheet or the Closing Statement of Assets
and Liabilities or as to whether the Closing Net Assets is
correct.  The Accounting Arbitrator shall make its determination
based solely on presentations and supporting material provided by
the parties and not pursuant to any independent review.  The
determination of the Accounting Arbitrator shall be final and
binding upon Buyer and Seller.  Judgment may be entered upon the
determination of the Accounting Arbitrator in any court having
jurisdiction over the party against which such determination is
to be enforced.  The fees, expenses and costs of the Accounting
Arbitrator shall be borne one-half by Buyer and one-half by
Seller.

          (f)  If the Closing Net Assets as finally determined in
accordance with this Section 4.2 are less than $24,957,762, the
Purchase Price shall be decreased on a dollar-for-dollar basis by
the amount of such shortfall, and if the Closing Net Assets are
greater than $24,957,762, the Purchase Price shall be increased
on a dollar-for-dollar basis by the amount of such excess.

          (g)  If any adjustment under this Section 4.2 results in a
reduction in the Purchase Price, Seller shall pay to Buyer the
amount of such reduction, and if any adjustment results in an
increase in the Purchase Price, Buyer shall pay to Seller the
amount of such increase, in each case, by wire transfer of
immediately available funds to an account designated by the party
receiving payment within five (5) Business Days after the final
determination of the amount of such reduction or increase in
Purchase Price, plus interest on the amount of such reduction or
increase from the Closing Date to the date of such payment
thereof at the per annum rate equal to the rate announced by
Citibank, N.A. in the City of New York as its base rate in effect
on the Closing Date.

   4.3.  Allocations; Taxes.

          (a)  The consideration (within the meaning of Section 1060
of the Code) paid by Buyer hereunder shall be allocated among the
Assets in accordance with a schedule to be prepared by Buyer.
Buyer shall deliver to Seller a draft schedule not later than
thirty (30) days after the final determination of the Closing Net
Assets pursuant to Section 4.2.  Seller shall have thirty (30)
Business Days to provide Buyer with any objections to such draft
schedule.  If Seller shall object to the computation or
allocation by Buyer of such amounts and Buyer and Seller shall
not reach agreement on the computation or allocation within
thirty (30) Business Days after notification by Seller of its
objection, then such disagreements shall be submitted for final
and binding resolution to an Accounting Arbitrator chosen in
accordance with the terms of Section 4.2(e).

          (b)  Such consideration allocation shall be made consistent
with Section 1060 of the Code.  Each of the parties hereto shall
not, and shall not permit any of its Affiliates to, take a
position (except as required pursuant to any Order) on any Tax
Return, or before any Taxing Authority or in any judicial
proceeding to the extent Tax issues are raised, that is in any
way inconsistent with the allocation of the consideration among
the assets determined in accordance with Section 4.3(a).

          (c)  Buyer and Seller shall cooperate in preparing,
executing and filing use, sales, real estate, transfer and
similar Tax Returns relating to the purchase and sale of the
Assets.  Such Tax Returns shall be prepared in a manner that is
consistent with the determination of the aggregate fair market
values of the Assets as contemplated by Section 4.3(a).  Each of
Buyer and Seller shall bear, and to the extent permitted by law
shall pay, 50% of all sales, transfer, documentary, stamp,
recording and similar Taxes incurred in connection with the
purchase and sale of the Assets ("Transfer Taxes"), and Buyer and
Seller shall reimburse each other for 50% of any Transfer Taxes
paid by the other party within fourteen (14) days of such other
party's written request.  Notwithstanding anything to the
contrary contained herein, Buyer shall be responsible for 100% of
any Transfer Taxes incurred in connection with the purchase and
sale of the Assets if such Transfer Taxes would be payable by
Seller as a result of Buyer's failure to (i) obtain the necessary
sales and use tax permits in the states of Maryland and Texas or
(ii) timely deliver any necessary resale certificates.

   4.4.  Allocation of Expenses.  The following expenses 
attributable to the Business shall be allocated between and are hereby 
assumed by Buyer and Seller as follows:

          (a)  All state, county and local ad valorem Taxes on real or
personal property ("Property Taxes") shall be prorated between
Buyer and Seller as of the Closing Date, computed by multiplying
the amount of Property Taxes for the fiscal year for which the
same are levied by a fraction, the numerator of which is the
number of days in such fiscal year up to and including the
Closing Date and the denominator of which is the number of days
in such fiscal year.  In connection with such proration of
Property Taxes, in the event that actual Property Tax figures are
not available at the Closing Date, proration of Property Taxes
shall be based upon the actual Property Taxes for the preceding
fiscal year for which actual Property Tax figures are available,
and re-prorated when actual Property Tax figures become
available.  All utility charges, gas charges, electric charges,
water charges, water rents and sewer rents, if any, shall be
apportioned between Buyer and Seller as of the Closing Date,
computed on the basis of the most recent meter charges or, in the
case of annual charges, on the basis of the established fiscal
year.  All prepaid expenses (including any lease payment but
excluding Taxes) paid by Seller prior to the Closing Date and all
other expenses paid by the Seller in respect of the Business
shall be apportioned between Buyer and Seller as of the Closing
Date computed on the basis of the applicable time period to which
the expenses apply.

          (b)  All prorations shall be made, insofar as feasible, on
the Closing Date, and the Purchase Price shall be adjusted in the
same manner as adjustments for indemnification payments as set
forth in Section 9.4(b)(ii).  During the three-month period
subsequent to the Closing Date, Seller shall advise Buyer and
Buyer shall advise Seller of any actual changes to such
prorations, and the Purchase Price shall be increased or
decreased, as applicable, at the end of such three-month period.
In the event Buyer or Seller shall receive bills after the
Closing Date for expenses incurred prior to the Closing Date that
were not prorated in accordance with Section 4.4(a) or that were
re-prorated in accordance with Section 4.4(a), then Buyer or
Seller, as the case may be, shall promptly notify the other party
as to the amount of the expense subject to proration and the
responsible party shall pay its portion of such expense (or, in
the event such expense has been paid on behalf of the responsible
party, reimburse the other party for its portion of such
expenses).
                                
                            ARTICLE V
                                
            REPRESENTATIONS AND WARRANTIES OF SELLER
                                
          The representations and warranties of Seller contained
in this Article V (other than those contained in Section 5.2,
Section 5.6(a) and Section 5.9(iv)) shall be deemed true, correct
and complete, and Seller shall not be deemed to have breached any
such representation or warranty as a consequence of the existence
of any fact, event or circumstance inconsistent with such
representation or warranty, unless such fact, event or
circumstance, individually or taken together with all other
facts, events or circumstances inconsistent with any
representation or warranty contained in this Article V, has had
or could reasonably be expected to have a Business Material
Adverse Effect, disregarding for these purposes (i) any
qualification or exception for, or reference to, materiality in
any such representation or warranty and (ii) any use of the terms
"material", "materially," "in all material respects" or similar
terms or phrases in any such representation or warranty.  The
representations and warranties in Section 5.9(iv) shall be deemed
to be true, correct and complete, and shall not be deemed to have
been breached, unless they are untrue, incorrect or incomplete in
any material respect.  The representations and warranties in
Section 5.2 and Section 5.6(a) shall not be qualified by either
of the two preceding sentences.

          Except as set forth on the Schedules (it being
understood that an item included on a Schedule referenced in any
Section or subsection of this Article V shall be deemed to relate

creditors, and (ii) general principles of equity (regardless of

consummation of the Transactions will not (with or without notice or 
lapse of time or both) (i) violate or conflict with the provisions of

approval or authorization of, or registration or filing with, any

Regulation and the National Industrial Security Program Operating
Manual, as may be amended from time to time; and

           (iv)  The Governmental Authorizations set forth on Schedule 5.4.

         (b)  Schedule 2.1(f) and Schedule 2.2(k) set forth all
Governmental Authorizations owned, held or possessed by Seller
that are necessary to own or lease, operate and use the Assets
and to carry on and conduct the Business substantially as
conducted immediately prior to the date of this Agreement other

own, hold or possess would not result in a Loss to the Business
of more than $1,000 individually or $5,000 in the aggregate.


   5.5.  Financial Information.

          (a)  Seller has delivered to Buyer and Schedule 5.5(a)
contains true, correct and complete copies of (i) unaudited pro

material respects the assets, liabilities and financial condition

of a nature customarily reflected on a balance sheet other than
Liabilities incurred since June 28, 2002 in the ordinary course
of business and consistent with past practice.

   5.6.  Events Subsequent to Date of Balance Sheet.  Except as set

certain services and support to the Business.  Buyer recognizes that such
services and support are necessary for the ongoing operation of
the Business, and that the assets owned by Seller which are
necessary to provide such services and support will not be
purchased by Buyer under this Agreement.  Accordingly, Buyer
recognizes that, in order to conduct the Business, Buyer must
provide, or contract with a third party to provide, the services
and support currently being provided by Seller.

has evaluated such documents and information, as it has deemed
necessary in connection with the execution, delivery and
performance of this Agreement.  Buyer acknowledges that it is
acquiring the Business without any representation or warranty,
express or implied, by Seller or any of its Affiliates except as
expressly set forth herein.  In furtherance of the foregoing, and
not in limitation thereof, Buyer acknowledges that no
representation or warranty, express or implied, of Seller or any
of its advisors, including, without limitation, Wachovia
Securities Inc., or any of their respective Affiliates or
representatives, with respect to the Business, including, without
limitation, (a) the information set forth in the Confidential
Information Memorandum relating to the Business dated June 2002,
(b) any other information provided to Buyer pursuant to the
Confidentiality Agreement or Section 8.15 or (c) any financial
projection or forecast delivered to Buyer with respect to the
revenues or profitability which may arise from the operation of
the Business either before or after the Closing Date, shall
(except as otherwise expressly represented to in this Agreement)
form the basis of any claim against Seller or any of its advisors
including, without limitation, Wachovia Securities Inc., or any
of their respective Affiliates or representatives with respect
thereto or with respect to any related matter.  With respect to
any projection or forecast delivered by or on behalf of Seller to
Buyer, Buyer acknowledges that (x) there are uncertainties
inherent in attempting to make such projections and forecasts,
(y) the accuracy and correctness of such projections and
forecasts may be affected by information which may become
available through discovery or otherwise after the date of such
projections and forecasts and (z) it is familiar with each of the
foregoing.  Buyer has no knowledge of any facts and/or
circumstances that would make any of the representations and
warranties of Seller contained in Article V untrue or misleading.
Nothing contained in this Section 6.09 will be construed as a
waiver of a defense to claims for fraud.
