                  (b) Net Proceeds from Sale or Financing allocable to the

to the holder of the Membership Interest on the date of distribution.

         7.5. Distributions to Pay Taxes.

                  (a) The Company shall use its best efforts to distribute
sufficient Net Cash from Operations to the Members each year to provide each
Member with sufficient cash to fund the payment of federal and state income tax
liabilities attributable to such Member's interest in the Company. The Board
shall take this goal into account in formulating any cash flow plan for the
Company. For this purpose, the Board shall make a theoretical calculation of the
Members tax liabilities based on reasonable assumptions and projections of the
Members' taxable income and the character thereof, including the then prevailing
maximum regular or alternative minimum Federal, state and local tax rates,
income based on the net cumulative amount of taxable income attributable to the
Company (i.e., income shall be netted against loss on a cumulative basis to the
extent that such offsets are allowable under then prevailing law and
regulations), and utilization of all items of loss and credit.

                  (b) Such distributions to pay taxes shall be made to the
Members in proportion to their respective allocable shares of Net Profits
calculated above for such Fiscal Year determined in accordance with the
provisions of the attached Tax Compliance Addendum hereof.

                  (c) The Board, shall, in its reasonable discretion, adjust the
rates of such distributions and the method of calculation provided for in this
Section 7.5 to reflect varying rates of taxation for unearned income, long-term
capital gains, or similar items, to account for tax liability arising as a
result of the application of the alternative minimum tax for individuals, or any
other changes made to the Code or the Virginia income tax laws that has the
effect of requiring the Member to pay more or less of those taxes on income
generated by the Company's operations.

                  (d) The distributions to pay taxes required by this Section
7.5 shall not be made if, in the reasonable opinion of the Board, such
distributions would significantly impair the Company's financial status and
impair its ability to conduct business operations as contemplated. Furthermore,
such distributions shall not be made in contravention of applicable laws of the
Commonwealth of Virginia.

                  (e) To the extent the Company does not distribute cash to pay
taxes for any given Fiscal Year, the Company shall distribute such cash in
subsequent years after making distributions for current taxes of such years and
prior to making any other distributions.

         7.6. Interim Distributions.

                  The Board, in its reasonable discretion, shall make interim
distributions of cash to pay taxes or of Net Cash from Operations during a
Fiscal Year; provided, however, that when financial statements for each Fiscal
Year are complete, the amount properly distributable to the Members for that
Fiscal Year shall be determined and the interim distributions of cash to pay
taxes, Net Proceeds from Operations, and all other distributions to the Members
(both for that Fiscal Year, and, if need be, for subsequent Fiscal Years), shall
be adjusted to reflect the amount properly distributable to each Member for that
Fiscal Year.

in carrying on the business of the Company; except that the compensation or
price therefor shall not exceed that prevailing in arm's length transactions by
others rendering similar services on comparable transactions as an on-going
activity in the same geographical area. Provided, however, if such business
falls into the category of a Major Decision, then the provisions contemplated in
this Agreement for approval of Major Decisions shall apply.

12. EXCULPATION AND INDEMNIFICATION OF THE MANAGERS AND OFFICERS.

         12.1. Exculpation of the Managers and Officers.

                  The Manager and Officers of the Company shall not be liable,
responsible, or accountable in damages or otherwise to the Company or to any
Member, or to any successor, assignee, or transferee of the Company or of any
Member, for any losses, claims, damages, or liabilities arising from (i) any act
performed, or the omission to perform any act, within the scope of the authority
conferred on the Manager and Officers by this Agreement, except by reason of
acts or omissions of a Manager or Officer found by a court of competent
jurisdiction upon entry of a final judgment to be due to bad faith, fraud,
willful misconduct, or a knowing violation of the criminal law; (ii) the
performance by a Manager or Officer of, or the omission to perform, in good
faith any acts on advice of legal counsel, accountants, or other professional
consultants to the Company; or (iii) the negligence, dishonesty, or bad faith of
any consultant, employee, or agent of the Company selected or engaged by a
Manager or Officer in good faith.

         12.2. Indemnification and Advances to the Manager and Other Persons.

                  (a) The Company shall, subject to the limitations of Section
12.1, indemnify, defend, and hold each Manager and Officer harmless from and
against, and hold the Company's and the Manager's or Officer's respective
Affiliates, agents, employees, advisors, consultants, and other independent
contractors harmless from and against any loss, liability, damage, fine,
judgment, penalty, attachment, cost, or expense, including reasonable attorneys'
fees, arising from any demands, claims, or lawsuits against the Manager or
Officer or the Company's or the Manager's of Officer's respective Affiliates,
agents, employees, advisors, consultants, or other independent contractors, in
or as a result of or relating to its capacity, actions, or omissions as a

                                      -12-


Manager of Officer, or as an Affiliate, agent, employee, advisor, consultant, or
other independent contractor of the Company, the Board or a Manager or Officer,
or arising from or relating to the business or activities undertaken on behalf
of the Company, including, without limitation, any demands, claims, or lawsuits
initiated by a Member; provided that the acts or omissions of the Manager or
Officer or the Company's or the Manager's of Officer's Affiliate, agent,
employee, advisor, consultant, or other independent contractor seeking
indemnification are not found by a court of competent jurisdiction upon entry of
a final judgment to be the result of bad faith, fraud, willful misconduct, or a
knowing violation of the criminal law of the person seeking indemnification, or
to have violated such a lesser standard of conduct as under applicable law
affirmatively prevents indemnification hereunder. The termination of any action,
suit or proceeding by judgment, order, settlement, plea of nolo contendere or
its equivalent, or conviction shall not, of itself, create a presumption that
the Manager of Officer or the Company's or the Manager's or Officer's respective
Affiliates, agents, employees, advisors, consultants, or other independent
contractors shall not be entitled to indemnification hereunder or that the
Manager of Officer or the Company's or the Manager's or Officer's respective
Affiliates, agents, employees, advisors, consultants, or other independent
contractors did not act in good faith and in a manner which it or they
reasonably believed to be in or not opposed to the best interests of the
Company.

                  (b) In the event the indemnification obligation of this
Section 12.2 shall be deemed unenforceable to any extent by a court of competent
jurisdiction, such unenforceable portion shall be modified or stricken so as to
give effect to this Section 12.2 to the fullest extent permitted by law.

                  (c) The right of indemnification hereby provided shall not be
exclusive of or affect any other rights that a Manager or Officer or any of its
Affiliates may have. Nothing contained in this Section 12.2 shall limit any
lawful rights to indemnification existing independently of this Section 12.2.

                  (d) Notwithstanding anything contained herein to the contrary,
any amount which the Manager or Officer or the Company's or the Manager's or
Officer's respective Affiliates, agents, employees, advisors, consultants, and
other independent contractors is entitled to receive under this Section 12.2
shall be paid only out of the assets of the Company and any insurance proceeds
available to the Company for such purposes. Notwithstanding anything contained
herein to the contrary or under any law, no Member of the Company shall be
personally liable for the payment of any amount that a Manager or Officer or an
Affiliate, agent, employee, advisor, consultant, or other independent contractor
of the Company or a Manager or Officer is entitled to receive under this Section
12.2, to make any capital contribution to the Company or to return any capital
distribution made to it by the Company or to restore any negative capital
account balance of that Member, to enable the Company to make any payment under
this Section 12.2.

                  (a) Funds of the Company shall be deposited in such account or
accounts of a type, in form and name, and in a bank(s) or other financial
institution(s) the deposits of which are insured by the Federal Deposit
Insurance Corporation or other depository insurance institutions, as selected by
the Board. The Board shall arrange for the appropriate conduct of such accounts.
Funds may be withdrawn from such accounts only for bona fide and legitimate
Company purposes and may from time to time be invested in such short-term
securities, money market funds, certificates of deposit, or other liquid assets
as the Board deems appropriate.

                  (b) The Members acknowledge that the Board may maintain
Company funds in accounts, money market funds, certificates of deposit, or other
liquid assets in excess of the insurance provided by the Federal Deposit
Insurance Corporation or other depository insurance institutions, and that the
Board shall not be accountable or liable for any loss of such funds resulting
from failure or insolvency of the depository institution holding such funds.

and supporting documents, which shall reflect, completely, accurately, and in
reasonable detail, each transaction of the Company (including, without
limitation, transactions with the Managers, Officers, Members, or Affiliates of
a Manager, Officer or any Member). The books of account, records, and all
documents and other writings of the Company shall be kept and maintained either
at the principal office of the Company described in Section 3.2, or at the
principal office of the Company.

                  (b) Required Records. The Board shall cause the Company to

                           (i) a current list of the full name and last known
business address of each Member, in alphabetical order;

                           (ii) a copy of the Certificate of Formation of the
Company, and all Articles of Amendment and Certificates of Amendment thereto;

                           (iii) copies of the Company's federal, state, and
local income tax returns and reports, if any, for the three most recent years;

                           (iv) a copy of this Agreement, as amended;

                           (v) copies of the Company's financial statements for
the three most recent years.

14. DISSOLUTION AND TERMINATION.

         14.1. Events Causing Dissolution and Winding Up.

                  The Company shall be dissolved and wound up upon the first to
occur of one of the following events:

                  (a) As required by specific provisions of this Agreement.

                  (b) As otherwise required by the Act.

         14.2. Liquidating the Company.

                  (a) if the Board determines that it is in the best interest of
the Company and the Members, the Board may sell or otherwise liquidate the
Company assets in a bona fide sale or sales to outsiders at such prices, and
upon such terms and at such times as it may determine, having due regard to the
activity and the condition of the relevant market and general financial and
economic conditions and consistent with its fiduciary obligations to the
Members. During the period of winding up of the Company, the party responsible
therefor may exercise all powers granted to the Board under this Agreement, and
may adopt such plan, method, or procedure as may be reasonable to effect an
orderly winding up.

                  (b) (i) After paying or providing for the payment of all
Company debts, the proceeds of sale shall be distributed as Net Proceeds from
Sale to the Members in accordance with their Capital Accounts after adjustments
thereof to reflect allocations in accordance with the Tax Compliance Addendum
and distributions under Sections 7.



                                      -14-


                           (ii) If the liquidating party determines that an
immediate sale would be financially inadvisable, it may defer sale of the
Company assets for a reasonable time, or distribute the assets in kind. If any
assets are distributed in kind, then they shall be distributed on the basis of
the fair market value thereof as determined by appraisal, and shall be deemed to
have been sold at fair market value for purposes of the allocations under the
Tax Compliance Addendum. Unless the Members otherwise agree, there shall be
distributed to the Members, as tenants-in-common, undivided interests in the
assets equal to the distributions to which they are entitled under Section 7.

                  (c) If the Company is "liquidated" within the meaning of
Regulations Section 1.704-1(b)(2)(ii)(G), then the liquidating distribution
shall be made by the later of (i) the end of the Company Fiscal Year in which
liquidation occurs, or (ii) ninety (90) days after the date of liquidation.

                  (d) Within a reasonable time following the completion of the
liquidation of the Company, the Board shall supply to each of the Members a
statement that shall set forth the assets and the liabilities of the Company as
of the date of complete liquidation and each Member's portion of the
distributions pursuant to this Agreement. Upon completion of the liquidation of
the Company and the distribution of all Company assets, the Company shall
terminate, and the Board shall have the authority to execute and record a
Certificate of Cancellation of the Company as well as any and all other
documents required to effectuate the dissolution and termination of the Company.

Agreement or law shall operate as a waiver thereof. No waiver by any party of

                  Except as set forth herein, all rights, powers, and remedies
herein given to the parties are cumulative and not alternative, and are in
addition to all statutes or rules of law; any forbearance or delay by the
parties in exercising the same shall not be deemed to be a waiver thereof, and
the exercise of any right or partial exercise thereof shall not preclude the

method of allocation of Net Profits or Net Losses or Gain or Loss from Sale as

shall require the approval of the Member affected; except that the Board is
authorized to modify Section 7 or the Tax Compliance Addendum, without the
consent of the Members, if, upon advice of counsel for the Company, the
modification is necessary to cause the allocations under Section 7 or the Tax
Compliance Addendum to have substantial economic effect or to be in accordance
with the Members' Membership Interests under Section 704 of the Code and the
most recently proposed or final regulations thereunder, so long as the
modification does not, by its terms, alter the limited liability of the Members
and provided that such modification is not likely to have a material effect on
the amounts distributable to any Member pursuant to this Agreement.

         IN WITNESS WHEREOF, the undersigned have each executed or caused this

                             Tax Compliance Addendum

TA.1  Maintenance of Members' Capital Accounts.

         TA.1(a) Notwithstanding anything to the contrary set forth in the
Agreement, the Members acknowledge and agree their desire to establish and
maintain Capital Accounts in accordance with Section 1.704-1(b) of the
Regulations and in compliance therewith agree that the following adjustments
shall apply to the establishment or maintenance of their capital accounts:

                  TA.1(a)(i) There shall be credited to each Member's Capital
Account the amount of any cash (which shall not include imputed or actual
interest on any deferred contributions) actually contributed by such Member to
the capital of the Company, the Fair Market Value of any property contributed by
such Member to the capital of the Company (net of any liabilities secured by
such property that the Company is considered to assume or take subject to under
Section 752 of the Code), such Member's share of the Net Profits of the Company
and of any items in the nature of income or gain separately allocated to the
Members and such Member's share of any adjustments pursuant to Section 48(q)(2)
of the Code; and there shall be charged against each Member's Capital Account
the amount of all cash distributions to such Member, the Fair Market Value of
any property distributed to such Member by the Company (net of any liability
secured by such property that the Member is considered to assume or take subject
to under Section 752 of the Code), such Member's share of the Net Losses of the
Company and of any items in the nature of losses or deductions separately
allocated to the Members and such Member's share of any adjustments pursuant to
Section 48(q)(1) of the Code.

                  TA.1(a)(ii) If the Company at any time distributes any of its
assets in-kind to any Member, the Capital Account of each Member shall be
adjusted to account for that Member's allocable share (as determined under
Section TA.2 below) of the Net Profits or Net Losses that would have been
realized by the Company had it sold the assets that were distributed at their
respective fair market values immediately prior to their distribution.

                  TA.1(a)(iii) In the event that the Company makes an election
under Section 754 of the Code, the amounts of any adjustments to the bases (or
Carrying Values) of the assets of the Company made pursuant to Section 743 of
the Code shall not be reflected in the Capital Accounts of the Members, but the
amounts of any adjustments to the bases (or Carrying Values) of the assets of
the Company made pursuant to Section 734 of the Code as a result of the
distribution of property by the Company to a Member (to the extent that such
adjustments have not previously been reflected in the Members' Capital Accounts)
shall be reflected in the Capital Accounts of the Members in the manner
prescribed in Regulations under Section 704(b) of the Code.

                  TA.1(a)(iv) If elected by the Company, upon the occurrence of
any of the following events, the Capital Account balance of each Member shall be
adjusted to reflect the Member's allocable share (as determined under Section
TA.2) of the Net Profits or Net Losses that would be realized by the Company if
it sold all of its property at its fair market value on the day of the
adjustment:

                           TA.1(a)(iv)(A) any increase in any new or existing
Membership Interest in the Company resulting from the contribution of cash or
property by such Member to the Company;

                           TA.1(a)(iv)(B) any reduction in a Membership Interest
in the Company resulting from a distribution to such Member in redemption of all
or a portion of such Membership Interest in the Company; and




                           TA.1(a)(iv)(C) whenever else allowed under applicable
Regulations.

                  TA.1(a)(v) In the event any interest in the Company is
transferred in accordance with the terms of this Agreement, the transferee shall
succeed to the Capital Account of the transferor to the extent it relates to the
transferred interest.

                  TA.1(a)(vi) To the extent that the Company makes any payment
that is treated as a syndication expense or organization expense under Section
709 of the Code and is not amortized (a "Syndication Cost"), such payment shall
be charged, at that time, against the Members' Capital Accounts. If at any time
thereafter, the Company takes a deduction for federal income tax purposes which
is attributable to such payment (or a portion thereof), such deduction shall be
allocated solely to the Members, but no adjustment of the Capital Accounts of
the Members as a group shall be made upon the deduction of such Syndication
Cost.

         TA.1(b) The Members acknowledge and agree that the provisions of
Section TA.1(a) above relating to the establishment and maintenance of Capital
Accounts are intended by the Members to describe and comply with the
requirements of applicable Regulations and are not intended to modify or create
independent rights among the parties except to the extent required to comply
with applicable Regulations that must be complied with in order for the
allocations of Net Profit and Net Loss provided in this Agreement to have
"economic effect" under applicable Regulations.

TA.2  Allocations of Net Profits, Net Losses and Credits.

Except as expressly otherwise provided in this Agreement, the Company's Net
Profits or Net Losses and tax credits for a calendar year shall be allocated
among the Members for the calendar year as follows.

         TA.2(a) Credits. All tax credits (and credit recapture, if any) shall
be allocated in the manner specified by the Code and the Regulations.

         TA.2(b) Net Profits and Net Losses.

                  TA.2(b)(i) Net Profits. After making the special allocations
required by Sections TA.2(c) and TA.2(e)-(j), and except as provided in Section
TA.2(d), the Net Profits and Net Losses for each calendar year shall be
allocated to the Members pro rata, in proportion to their respective Membership
Interest or as otherwise required by the Code.

                  TA.2(b)(ii) Net Losses. After making the special allocations
required by Sections TA.2(c) and TA.2(e)-(j) and except as otherwise provided in
Section TA.2(d), the Net Losses of the Company for any calendar year shall be
allocated to the Members pro rata, in proportion to their respective Membership
Interest or as otherwise required by the Code.

         TA.2(c) Contributed Property. Income, gain, loss, deduction with
respect to property contributed to the Company by a Member or property the
Carrying Value of which is adjusted in accordance with the terms of this
Agreement shall be allocated among the Members in accordance with Section 704(c)
of the Code. This allocation is for tax purposes only and shall not affect the
Member's Capital Accounts.

         TA.2(d) Allocations Upon Dissolution. Upon the dissolution of the
Company, Net Profits and Net Losses, including Net Profits from the sale shall
be allocated first to the Members in such proportions and in such amounts as
would result in the respective Capital Account balances of each Member being in
a ratio to the Capital Accounts of the other Members proportionate to the
respective Membership Interest of each of the Members. The remainder of the Net
Profits shall be allocated to the Members, pro rata, in proportion to their
respective Membership Interest.

                                      -2-


         TA.2(e) Company's Minimum Gain. Notwithstanding the provisions of
Sections TA.2(a) through (d), if in any year there is a net decrease in the
amount of the Company's Minimum Gain (including minimum gain attributable to
Member Nonrecourse Debt) each Member with a share of the Company's Minimum Gain
shall first be allocated items of Net Profits and gain for such year (and, if
necessary, subsequent years) in the amounts and in the manner required by
Section 1.704-2(f) of the Regulations.

         TA.2(f) Notwithstanding the provisions of Sections TA.2(a) through (d),
if, during any year a Member (i) is allocated pursuant to Section 706(d) of the
Code or Section 1.751-1(b)-(2)(ii) of the Regulations any Net Losses, deductions
or any expenditures described in Section 705(a)(2)(B) of the Code, (ii) is
distributed any cash or property from the Company to the extent such
distributions exceed offsetting increases to such Member's Capital Account that
are reasonably expected to occur during such year, or (iii) receives any other
adjustment, allocation or distribution described in Section
1.704-1(b)(2)(ii)(d)(4), (5) or (6) of the Regulations, and, as a result of such
adjustment, allocation or distribution, such Member has an Excess Negative
Balance in his Capital Account, then items of Net Profits and gain for such year
(and, if necessary, subsequent years) shall first be allocated to such Member in
an amount equal to its Excess Negative Balance.

         TA.2(g) Notwithstanding the provisions of Sections TA.2(a) through (d),
in no event shall Net Losses of the Company be allocated to a Member if such
allocation would result in such Member having an Excess Negative Balance in its
Capital Account.

         TA.2(h) Notwithstanding the provisions of Sections TA.2(a) through (d),
in the event that Net Profits, Net Losses or items thereof are allocated to one
or more Members pursuant to subsections (f) and (g) above, subsequent Net
Profits and Losses will first be allocated (subject to the provisions of
subsections (f) and (g)) to the Members in a manner designed to result in each
Member having a Capital Account balance equal to what it would have been had the
original allocation of Net Profits, Net Losses or items thereof pursuant to
subsections (f) and (g) not occurred.

         TA.2(i) Notwithstanding any other provision of this Section TA.2, the
amount of the Net Profits, Net Losses, credits, or other items thereof that will
be allocated to a Member shall not be less than a one percent (1%) of the amount
of such items in each calendar year.

         TA.2(j) The respective interests of the Members in the Net Profits and
Net Losses or items thereof shall remain as set forth above unless changed by
amendment to this Agreement or by an assignment of an interest in the Company
authorized by the terms of this Agreement. Except as otherwise provided herein,
for tax purposes, all items of income, gain, loss, deduction or credit shall be
allocated to the Members in the same manner as are Net Profits and Net Losses;
provided, however, that if the Carrying Value of any property of the Company
differs from its adjusted basis for tax purposes, then items of income, gain,
loss, deduction or credit related to such property for tax purposes shall be
allocated among the Members so as to take account of the variation between the
adjusted basis of the property for tax purposes and its Carrying Value in the
manner provided for under Section 704(c) of the Code.
