     Section 10.2. Other Income Taxes in General.

          (a) With respect to taxable periods of the Company ending on or before
the Closing Date, Seller shall prepare and file Tax Returns for and shall be
responsible for the payment of any state, local, or foreign income Taxes of the
Company not heretofore paid. Neither Buyer nor the Company shall be required to
reimburse Seller or any other person for any such Taxes. Seller and LGC shall
indemnify and hold Buyer and the Company harmless from all liabilities for any
such Taxes of the Company and any corporation with which the Company files or
has filed a unitary, consolidated, or combined return. Seller shall be entitled
to refunds (except any resulting from carrybacks from taxable periods ending
after the Closing Date) not heretofore received for taxable periods of the
Company ending on or before the Closing Date; provided, however, that any amount
payable by Buyer or the Company to Seller in respect of any such refund shall be

and hold Seller harmless from all state, local, or foreign income Taxes (except

adjustment to the Purchase Price) the amount of the Tax attributable to the
period through, but not paid before, the Closing Date. The Tax attributable to
the period through the Closing Date shall be determined as if that period were a
separate taxable year. Buyer shall notify Seller in writing of the amount of
such Tax. Within 30 days after the date of such notification, Seller shall pay
such amount to Buyer. Any payment made more than 30 days after Buyer initially
notifies Seller of the amount of such Tax shall include interest at the rate of

     Section 10.3. Section 338 Elections.

          (a) If the Call Option is exercised on the Closing Date by Buyer or
the Put Option is exercised on the Closing Date by Seller as provided under
Article III of this Agreement and Buyer requests that Seller (and/or LCG, as
appropriate) join it in making elections under Section 338(h)(10) of the Code
with respect to H&R Acquisition and H&R, Seller (and/or LGC as appropriate)
shall join in making such elections (and shall join in making any corresponding
elections under state Law) for the period ending at the end of the Closing Date.
Seller and LCG shall prepare and file the returns for, be responsible for the
payment of, indemnify and hold Buyer and H&R Acquisition and H&R harmless from,
and be entitled to any refund of any federal and state income Taxes resulting
from such elections (and any corresponding elections under state Law). The
parties acknowledge that the effect of elections under Section 338(h)(10) of the
Code with respect to H&R Acquisition and H&R will be to cause each of them to be
treated as two corporations for federal income Tax purposes: (i) an "old"
corporation, which shall be treated (a) as having sold all of its assets in a
taxable transaction as of the end of the Closing Date while a member of Seller's
affiliated group, and (b) as having completely liquidated pursuant to Sections
332 and 337 of the Code, and (ii) a "new" corporation, which shall be treated as
having purchased (as of the beginning of the day after the Closing Date) the
assets deemed sold by the old corporation. The parties hereto further intend for
such elections to be effective, if possible, for state (as well as federal)
income Tax purposes, and they shall timely execute and file any documents that
may be required under any applicable Law for such elections (or any
corresponding elections under state Law) to be effective for state income Tax
purposes.

          (b) If elections are made under Section 338(h)(10) pursuant to Section
10.3(a), Buyer and Seller shall cooperate as provided herein to determine, in
accordance with all applicable Treasury Regulations promulgated under Section
338 of the Code, the deemed sales prices of the assets of H&R Acquisition and
H&R. Buyer initially shall determine such deemed sales prices and shall notify
Seller in writing of the prices so determined ("Buyer's Deemed Sales Price
Notice") within 90 days after the Closing Date. Seller shall be deemed to have
accepted such determination unless, within 60 days after the date of Buyer's
Deemed Sales Price Notice, Seller notifies Buyer in writing of (i) each proposed
deemed sales price with which Seller disagrees, and (ii) for each such price,
the amount that Seller proposes as the deemed sales price. If Seller provides
such notice to Buyer, the parties shall proceed in good faith to determine
mutually the deemed sales prices in dispute. Except as otherwise agreed to by
both Buyer and Seller in writing, neither Buyer nor Seller shall take, nor shall
they permit any affiliated corporation (including, without limitation, H&R
Acquisition and H&R) to take, any position for income Tax purposes that is
inconsistent with the deemed sales prices as finally determined hereunder;
provided, however, that (i) the deemed purchase prices of the assets shall
differ from the deemed sales prices to the extent necessary to reflect the
inclusion in the total deemed purchase price of items (for example, Buyer's
capitalized acquisition costs) not included in the total deemed sales price and
(ii) the amount realized upon the deemed sale of assets may differ from the
deemed sales prices to reflect transaction costs that reduce the amount realized
for federal income Tax purposes.

          (c) If elections are made under Section 338(h)(10) pursuant to Section
10.3(a), Buyer and Seller (and/or LCG, as appropriate) shall execute IRS Form
8023 (or any applicable


                                      -42-
<PAGE>

successor form). Buyer shall retain custody of such form, and all required
attachments thereto, and shall file such form with the appropriate office(s) of
the IRS. Promptly after such filing, Buyer shall provide a photocopy of the form
(including all attachments) as filed to Seller.

     Section 10.4. Cooperation.

          (a) Buyer agrees to cooperate and to cause the Company to cooperate
with Seller to the extent reasonably required after the Closing Date in
connection with (i) the filing, amendment, preparation, and execution of all
income Tax Returns and other income Tax documents with respect to any taxable
period of the Company ending on or before the Closing Date, (ii) contests
concerning the application of any income Tax or the Tax due for any such period
and (iii) audits and other proceedings conducted by taxing authorities with
respect to any such period. Within a reasonable time after Buyer or the Company
receives official notice of any such contest, audit, or other proceeding, Buyer
shall notify or cause the Company to notify Seller of such contest, audit, or
other proceeding. In any case where the Company is responsible under applicable
law for the defense of such contest, audit, or other proceeding, Seller shall
have the right to conduct the defense at Seller's expense and in cooperation
with Buyer and the Company.

          (b) Seller and LGC shall hold the Indemnified Parties harmless from
any increase in income Tax (for any taxable period) and any other liability
resulting from adjustments to or changes in Tax items relating to the Company
for any taxable period ending on or before the Closing Date, whether such
adjustments or changes are voluntarily made or are required by a taxing
authority. Except as may be required by law or as provided in Section 10.4(d)
hereof, no amended income Tax Return shall be filed, and no change in any income
Tax accounting method and no income Tax election shall be made, by, on behalf of
or with respect to the Company for any taxable period ending on or before the
Closing Date without the express written consent of Seller and Buyer, which
consents will not be unreasonably withheld.

          (c) Seller and LGC agree to make available to Buyer and the Company
records in the custody of either Seller, LGC or any affiliated person, to
furnish other information (including, without limitation, all adjustments to and
changes in Tax items of the Company for taxable periods ending on or before the
Closing Date), and otherwise to cooperate to the extent reasonably required for
the preparation or filing of (i) Tax Returns and other income Tax documents
relating to the Company for taxable periods beginning on or ending after the
Closing Date or (ii) any required information return or report relating to
Buyer's acquisition of the Purchased Stock or the Option Shares from Seller.

          (d) Seller acknowledges that the Company and Buyer shall be entitled
to the income Tax benefit of any loss, credit, or other item of the Company that
(i) arises after the Closing Date, although such loss, credit, or other item may
be carried back to a taxable period ending on or before the Closing Date or (ii)
has arisen or arises before the Closing Date but is reportable in or carried
forward to a taxable period ending after the Closing Date.

Seller and LGC agree to cooperate with Buyer and the Company in taking such
action as may be necessary (including, without limitation, amending any Tax
Return and filing any claim for refund) for Buyer or the Company to realize the
Tax benefit of carrying a loss, credit, or other item arising after the Closing
Date back (if possible) to a taxable period ending on or before the Closing
Date. Seller and LGC promptly shall pay or cause to be paid to Buyer (i) any
amount received as a refund and (ii) if not realized as a refund, the amount of
any reduction in Tax liability (of the Company, Seller or any other member of
the affiliated group of which Seller is a member) resulting from the use of such
a loss, credit, or other item; provided, however, that the amount so payable by
Seller shall be reduced by the lesser of (i) the amount of any Taxes incurred or
(ii) the present value (based on a discount rate of 8%) of any Taxes to be
incurred, by Seller or any other such member of its affiliated group as a result
of the accrual or receipt of the refund.

     Section 10.5. Termination of Tax-Sharing Agreements.

     This Article X supersedes any and all tax-sharing or similar agreements to
which (a) the Company and (b) Seller or any affiliate of Seller are parties.
Neither the Company nor Seller (or any Affiliate of Seller or LGC) shall have
any obligation or right with respect to each other under any such agreement
after the Closing Date.

     Section 10.6.  Relationship of This Article X to Article IX.

     The indemnities provided in this Article are in addition to, but not in
duplication of, the indemnities provided in Article IX. The time limitations in
Sections 9.1(a) and 9.2(a) hereof, and the threshold and cap amounts in Sections
9.1(d) and 9.2(d) hereof, shall not apply to any claim or liability to which
this Article X applies or for breach of any covenant under this Article X.
Sections 9.1(c) and 9.2(c) hereof shall apply to third-party claims subject to
indemnification under this Article X, except that the provisions of this Article
X (rather than the provisions of Sections 9.1(c) and 9.2(c)) shall apply in the
event and to the extent of any inconsistency between Sections 9.1(c) and 9.2(c)
and this Article X. Sections 9.1 and 9.2 shall apply to Tax claims and
liabilities to which this Article X does not apply.

Law resulting from such termination.

agreements, understandings, negotiations and discussions of the parties, whether
oral or written. There are no warranties, representations or other agreements

specifically set forth herein. No amendment, supplement, modification or
termination of this Agreement shall be binding unless executed in writing by the

respective counsel, accountants and other experts and the other expenses
incident to the negotiation and preparation of this Agreement and consummation

agrees to be subject to (and hereby irrevocably submits to) the nonexclusive
jurisdiction of any United States federal or Virginia state court sitting in
Richmond, Virginia, in respect of any suit, action or proceeding arising out of
or relating to this Agreement or the transactions contemplated herein, and
irrevocably agrees that all claims in respect of any such suit, action or
proceeding may be heard and determined in any such court. Each of the parties
hereto irrevocably waives, to the fullest extent it may effectively do so under
applicable Law, any objection to the laying of the venue of any such suit,
action or proceeding brought in any such court and any claim that any such suit,
action or proceeding brought in any such court has been brought in an
inconvenient forum. Either party hereto may make service on the other party by
sending or delivering a copy of the process to the party to be served at the
address and in the manner provided for the giving of notices in Section 12.6
hereof. Nothing in this Section 12.3, however, shall affect the right of any
party to bring any action or proceeding arising out of or relating to this
Agreement in any other court or to serve legal process in any other manner
permitted by Law or in equity.

     Section 12.4.  Further Assurances.

     In case at any time after the Closing any further action is necessary or
desirable to carry out the purposes of this Agreement, each party to this
