     FOR VALUE RECEIVED, ETHYL CORPORATION, a Virginia corporation ("Borrower")
hereby promises to pay to the order of BRUCE C. GOTTWALD, SR., an individual

and/or any other permitted holder of this Note, as such successors, assigns or
holders are permitted pursuant to Section 12 below, "Lender"), without offset,
in immediately available funds in lawful money of the United States of America,
at 330 South Fourth Street, Richmond, Virginia 23219, the principal sum of
EIGHTEEN MILLION SIX HUNDRED FORTY THOUSAND AND NO/100 DOLLARS ($18,640,000.00)
(or the unpaid balance of all principal advanced against this Note, if that
amount is less), together with interest on the unpaid principal balance of this
Note from day to day outstanding as hereinafter provided.

     1. Payment Schedule and Maturity Date. Accrued unpaid interest on the
principal balance outstanding hereunder shall be due and payable monthly, in
arrears, commencing on March 1, 2002, and continuing on the 1st day of each
succeeding month thereafter until all principal and accrued interest owing on
this Note shall have been fully paid and satisfied. The entire principal balance
of this Note then unpaid shall be due and payable in full on January 31, 2005
(such date, or any earlier date on which any such amounts may become due and
payable pursuant to Section 9 hereof, the "Maturity Date").

     2. Security; Loan Documents. The security for this Note includes (i) a
Credit Line Deed of Trust (which, as it may have been or may be amended,
restated, modified or supplemented from time to time, is herein called the "Deed
of Trust") dated January 31, 2002 from Borrower to E. Kristen Moye and R. Gordon
Smith, as co-trustees, covering certain property in the City of Richmond,
Virginia described therein (the "Property"), and (ii) an Assignment of Rents,

Note, the Deed of Trust and the Assignment of Rents are, as the same have been
or may be amended, restated, modified or supplemented from time to time, herein

set forth on Schedule B thereto (the "Permitted Exceptions").

     3.  Interest Rate.

     (a) The unpaid principal balance of this Note from day to day outstanding,
which is not past due, shall bear interest at a fixed rate of interest equal to
eight and one-half percent (8.5%) per annum.

     (b) Any principal of, and to the extent permitted by applicable law, any
interest on this Note, and any other sum payable hereunder, which is not paid
when due shall bear interest, from the date due and payable until paid, payable
on demand, at a rate equal to ten and one-half percent per annum (the "Past Due
Rate").

     (c) Interest on this Note shall be computed for the actual number of days
which have elapsed, on the basis of a 360-day year.

     4.  Prepayment. Borrower may prepay the principal balance of this Note, in
full at any time or in part from time to time, without fee, premium or penalty,
provided that: (a) Lender shall have actually received from Borrower prior
written notice of (i) Borrower's intent to prepay, (ii) the amount of principal
which will be prepaid (the "Prepaid Principal"), and (iii) the date on which the
prepayment will be made; (b) each prepayment shall be in the amount of $1,000 or
a larger integral multiple of $1,000 (unless the prepayment retires the
outstanding balance of this Note in full); and (c) each prepayment shall be in
the amount of 100% of the Prepaid Principal, plus accrued unpaid interest
thereon to the date of prepayment, plus any other sums which have become due to
Lender under the Loan Documents on or before the date of prepayment but have not
been paid. Amounts prepaid hereunder may not be reborrowed.

     5.  Intentionally Deleted.

     6.  Certain Provisions Regarding Payments; "Put" Rights.

     (a) All payments made as scheduled on this Note shall be applied, to the
extent thereof, to late charges, to accrued but unpaid interest, unpaid
principal, and any other sums due and unpaid to Lender under the Loan Documents,
in such manner and order as Lender may elect in its sole discretion. All
permitted prepayments on this Note shall be applied, to the extent thereof, to
accrued but unpaid interest on the amount prepaid, to the principal, and any
other sums due and unpaid to Lender under the Loan Documents, in such manner and
order as Lender may elect in its sole discretion. Except to the extent that
specific provisions are set forth in this Note or another Loan Document with
respect to application of payments, all payments received by Lender shall be
applied, to the extent thereof, to the indebtedness secured by the Deed of Trust
in such manner and

                                      -2-

<PAGE>

order as Lender may elect in its sole discretion, any instructions from Borrower
or anyone else to the contrary notwithstanding. Remittances in payment of any
part of the indebtedness other than in the required amount in immediately
available U.S. funds shall not, regardless of any receipt or credit issued
therefor, constitute payment until the required amount is actually received by
Lender in immediately available U.S. funds and shall be made without offset,
demand, counterclaim, deduction, or recoupment (each of which is hereby waived)
and accepted subject to the condition that any check or draft may be handled for
collection in accordance with the practice of the collecting bank or banks.
Acceptance by the holder hereof of any payment in an amount less than the amount
then due on any indebtedness shall be deemed an acceptance on account only,
notwithstanding any notation on or accompanying such partial payment to the
contrary, and shall not in any way excuse the existence of an Event of Default.

     (b) At any time from the Maturity Date until thirty (30) days after the
Maturity Date, Borrower may satisfy all of its obligations to Lender under this
Note and the other Loan Documents, in full, by making a Qualified Transfer
(hereinafter defined). For purposes of this Note, a "Qualified Transfer" means
the delivery to Lender of a general warranty deed to the Property duly executed
by Borrower in recordable form reasonably satisfactory to Lender, together with
a title commitment issued by the Title Company (or such other title company as
may be reasonably acceptable to Lender) insuring Lender's title to the Property
as owner in the amount of the outstanding balance of the Note subject only to
the Permitted Exceptions, and such utility easements and rights of access
reasonably acceptable to Lender as may arise after the date of the Title Policy,
provided they do not adversely affect the utility or value of the Property, with
gap coverage.

     7.  Representations and Warranties. Borrower hereby represents and warrants
to Lender as follows:

     (a) Borrower is a corporation duly organized, validly existing and in good
standing under the laws of the Commonwealth of Virginia and has the power and
authority to own its property and to carry on its business in each jurisdiction
in which Borrower does business.

     (b) Borrower has full power and authority to execute and deliver the Loan
Documents and to incur and perform the obligations provided for therein, all of
which have been duly authorized by all proper and necessary action of the

Loan Document, and Borrower is in compliance with all laws and regulatory
requirements to which it is subject.

     (c) This Note and the other Loan Documents executed by Borrower constitute
valid and legally binding obligations of Borrower, enforceable in accordance
with their terms.

     (d) There is no proceeding against Borrower pending or, to the knowledge of
Borrower, threatened before any court or governmental authority, agency or
arbitration authority, which if adversely determined would have a material
adverse effect on Borrower or the Property, except as disclosed to Lender in
writing and acknowledged by Lender prior to the date of this Note.

                                      -3-

<PAGE>

     (e) There is no charter, bylaw, stock provision, or other document
pertaining to the organization, power or authority of Borrower and no provision
of any existing agreement, mortgage, indenture or contract binding on Borrower

execution, delivery or carrying out of the terms of this Note and the other Loan
Documents which has not been cured, waived or consented to.

     (f) Borrower has good title to the Property, and the Property is free and
clear of liens, except those granted to Lender and as disclosed to Lender in

payable by Borrower have been paid or are being contested in good faith by
appropriate proceedings and the Borrower has filed all tax returns which it is
required to file.

primarily to the environment or Hazardous Materials the violation of which would
have a material adverse effect on the Property.

     (i) All representations and warranties made under this Note shall be deemed
to be made at and as of the date hereof.

     8.  Affirmative Covenants. Until full payment and performance of all
obligations of Borrower under the Loan Documents, Borrower will, unless Lender
consents otherwise in writing (and without limiting any requirement of any other
Loan Document):

         (a) Financial Statements and Other Information. Unless written notice
of another location is given to Lender, Borrower's books and records concerning
the Property will be located at the Property. In addition, Borrower will furnish
to Lender promptly such information, reports and statements respecting the
Property from time to time, as Lender may reasonably request.

         (b) Insurance. Maintain the insurance coverage required by the Deed of
Trust and provide in such insurance for at least 30 days prior notice to Lender
of any cancellation thereof. Satisfactory evidence of such insurance will be
supplied to Lender 30 days prior to each policy renewal.

qualification to do business, where required and comply with all laws,
regulations and governmental requirements including, without limitation,
environmental laws applicable to it or to the Property.

         (d) Adverse Conditions or Events. Promptly advise Lender in writing of
(i) any condition, event or act which comes to its attention that would or might
materially adversely

                                      -4-

<PAGE>

affect the Property, and (ii) any event that has occurred that would constitute
an Event of Default under any Loan Documents.

         (e) Taxes and Other Obligations. Pay all of its taxes, assessments and
other obligations, including, but not limited to taxes, costs or other expenses
arising out of this transaction, as the same become due and payable, except to
the extent the same are (i) not yet delinquent or (ii) being contested in good
faith by appropriate proceedings in a diligent manner.

         (f) Environmental Matters. Promptly (and in any event within five days)
advise Lender in writing of (i) any and all enforcement, cleanup, remedial,
removal, or other governmental or regulatory actions instituted, completed or
threatened at the Property pursuant to any applicable federal, state, or local
laws, ordinances or regulations relating to any Hazardous Materials affecting
Borrower's business operations at the Property; and (ii) all claims made or
threatened by any third party against Borrower relating to damages,
contribution, cost recovery, compensation, loss or injury resulting from any
Hazardous Materials at the Property. Borrower shall promptly (and in any event
within five days) notify Lender of any remedial action taken by Borrower with
respect to Borrower's business operations at the Property. Borrower will not use
or permit any other party to use any Hazardous Materials at the Property except
such materials as are incidental to Borrower's normal course of business,
maintenance and repairs and which are handled in compliance with all applicable
environmental laws. Borrower agrees to permit Lender, its agents, contractors
and employees to enter and inspect the Property at any reasonable times upon
three (3) days prior notice for the purposes of conducting an environmental
investigation and audit to insure that Borrower is complying with this covenant.
Borrower shall provide Lender, its agents, contractors, employees and
representatives with access to and copies of any and all data and documents
relating to or dealing with any Hazardous Materials used, generated,
manufactured, stored or disposed of by Borrower's business operations at the
Property within five (5) days of the request therefore.

     9.  Events of Default.

         (a) It shall be an event of default ("Event of Default") under this
Note and each of the other Loan Documents if (i) any principal, interest or
other amount of money due under this Note is not paid in full when due,
regardless of how such amount may have become due; (ii) any covenant, agreement,
condition, representation or warranty herein or in any other Loan Documents is
not fully and timely performed, observed or kept after the expiration of any
applicable cure periods; or (iii) there shall occur any default or event of
default under the Deed of Trust or any other Loan Document, which is not cured
within the applicable cure periods provided therein. Upon the occurrence of an
Event of Default or upon the occurrence of any Event of Default, as defined
under that certain First Amendment and Restatement of Amended and Restated
Credit Agreement dated as of April 10, 2001 (as the same may have heretofore or
hereafter be amended, modified or supplemented, the "Syndicated Credit
Agreement") among the Borrower, the Subsidiary Guarantors (as defined therein),
the Banks (as defined therein) and Bank of America, N.A., as Administrative
Agent (the "Administrative Agent") and provided the Administrative Agent shall
have accelerated the Credit Party Obligations (as defined therein) in accordance
with the terms of the Syndicated Credit Agreement, Lender may (i) declare the
unpaid principal balance and

                                      -5-

<PAGE>

accrued but unpaid interest on this Note, and all other amounts due hereunder
and under the other Loan Documents, at once due and payable (and upon such
declaration, the same shall be at once due and payable), (ii) foreclose any
liens and security interests securing payment hereof, and (iii) exercise any of
its other rights, powers and remedies under this Note, under any other Loan
Document, or at law or in equity (subject to the provisions of Section 15
below). At any time from the Maturity Date until thirty (30) days after the
Maturity Date, Lender may, if all amounts outstanding on this Note are not paid,
in full, on the Maturity Date, demand that Borrower make a Qualified Transfer in
satisfaction of all amounts outstanding hereunder and Borrower shall make a
Qualified Transfer within fifteen (15) days of such demand.

         (b) All of the rights, remedies, powers and privileges (together,
"Rights") of Lender provided for in this Note and in any other Loan Document are
cumulative of each other and of any and all other Rights at law or in equity.
The resort to any Right shall not prevent the concurrent or subsequent
employment of any other appropriate Right. No single or partial exercise of any
Right shall exhaust it, or preclude any other or further exercise thereof, and
every Right may be exercised at any time and from time to time. No failure by
Lender to exercise, nor delay in exercising any Right, including but not limited
to the right to accelerate the maturity of this Note, shall be construed as a
waiver of any Event of Default or as a waiver of any Right. Without limiting the
generality of the foregoing provisions, the acceptance by Lender from time to
time of any payment under this Note which is past due or which is less than the
payment in full of all amounts due and payable at the time of such payment,
shall not (i) constitute a waiver of or impair or extinguish the right of Lender
to accelerate the maturity of this Note or to exercise any other Right at the
time or at any subsequent time, or nullify any prior exercise of any such Right,
or (ii) constitute a waiver of the requirement of punctual payment and
performance or a novation in any respect.

         (c) If any holder of this Note retains an attorney in connection with
any Event of Default or at maturity or to collect, enforce or defend this Note
or any other Loan Document in any lawsuit or in any probate, reorganization,
bankruptcy, arbitration or other proceeding, or if Borrower sues any permitted
holder in connection with this Note or any other Loan Document and does not
prevail, then Borrower agrees to pay to each such holder, in addition to
principal, interest and any other sums owing to Lender hereunder and under the
other Loan Documents, all costs and expenses incurred by such permitted holder
in trying to collect this Note or in any such suit or proceeding, including,
without limitation, reasonable attorneys' fees and expenses, investigation costs
and all court costs, whether or not suit is filed hereon, whether before or
after the Maturity Date, or whether in connection with bankruptcy, insolvency or
appeal, or whether collection is made against Borrower or any guarantor or
endorser or any other person primarily or secondarily liable hereunder.

     10. Commercial Purpose. Borrower warrants that the Loan is being made
solely to acquire or carry on a business or commercial enterprise, and/or
Borrower is a business or commercial organization. Borrower further warrants
that all of the proceeds of this Note shall be used for commercial purposes and
stipulates that the Loan shall be construed for all purposes as a commercial
loan, and is made for other than personal, family, household or agricultural
purposes.

                                      -6-

     11. WAIVER OF JURY TRIAL. BORROWER WAIVES TRIAL BY JURY IN ANY ACTION OR
PROCEEDING TO WHICH BORROWER AND LENDER MAY BE PARTIES, ARISING OUT OF, IN
CONNECTION WITH OR IN ANY WAY PERTAINING TO, THIS NOTE, THE DEED OF TRUST OR ANY
OF THE OTHER LOAN DOCUMENTS. IT IS AGREED AND UNDERSTOOD THAT THIS WAIVER
CONSTITUTES A WAIVER OF TRIAL BY JURY OF ALL CLAIMS AGAINST ALL PARTIES TO SUCH
ACTION OR PROCEEDINGS, INCLUDING CLAIMS AGAINST PARTIES WHO ARE NOT PARTIES TO
THIS NOTE. THIS WAIVER IS KNOWINGLY, WILLINGLY AND VOLUNTARILY MADE BY BORROWER,
AND BORROWER HEREBY REPRESENTS THAT NO REPRESENTATIONS OF FACT OR OPINION HAVE
BEEN MADE BY ANY INDIVIDUAL TO INDUCE THIS WAIVER OF TRIAL BY JURY OR TO IN ANY
WAY MODIFY OR NULLIFY ITS EFFECT. BORROWER FURTHER REPRESENTS AND WARRANTS THAT
IT HAS BEEN REPRESENTED IN THE SIGNING OF THIS NOTE AND IN THE MAKING OF THIS
WAIVER BY INDEPENDENT LEGAL COUNSEL, OR HAS HAD THE OPPORTUNITY TO BE
REPRESENTED BY INDEPENDENT LEGAL COUNSEL SELECTED OF ITS OWN FREE WILL, AND THAT
IT HAS HAD THE OPPORTUNITY TO DISCUSS THIS WAIVER WITH COUNSEL.

     12. Heirs, Successors and Assigns. The terms of this Note and of the other
Loan Documents shall bind and inure to the benefit of the heirs, devisees,
representatives, successors and permitted assigns of the parties, provided
however, Bruce C. Gottwald, Sr. shall be permitted to make the following
transfers of his interest in this Note and any other documents executed in
connection therewith: (i) an assignment to his estate upon death in accordance
with applicable law, (ii) an assignment to his wife or children for tax and
estate planning purposes, and (iii) a collateral assignment to his own lender to
secure financing provided to Bruce C. Gottwald in connection with the Property.
The foregoing sentence shall not be construed to permit Borrower to assign the
loan except as otherwise permitted under the loan documents.

     13. General Provisions. Time is of the essence with respect to Borrower's
obligations under this Note. If more than one person or entity executes this
Note as Borrower, all of said parties shall be jointly and severally liable for
payment of the indebtedness evidenced hereby. Borrower and all sureties,
endorsers, guarantors and any other party now or hereafter liable for the
payment of this Note in whole or in part, hereby severally (a) waive demand,
presentment for payment, notice of dishonor and of nonpayment, protest, notice
of protest, notice of intent to accelerate, notice of acceleration and all other
notices (except any notices which are specifically required by this Note or any
other Loan Document), filing of suit and diligence in collecting this Note or
enforcing any of the security herefor; (b) agree to any substitution,
subordination, exchange or release of any such security or the release of any
party primarily or secondarily liable hereon; (c) agree that Lender shall not be
required first to institute suit or exhaust its remedies hereon against Borrower
or others liable or to become liable hereon or to perfect or enforce its rights
against them or any security herefor; (d) consent to any extensions or
postponements of time of payment of this Note for any period or periods of time
and to any partial payments, before or after maturity, and to any other
indulgences with respect hereto, without notice thereof to any of them; and (e)
submit (and waive all rights to object) to non-exclusive personal jurisdiction
of any state or federal court sitting in the Commonwealth of Virginia, and venue
in the city or county in

                                      -7-

<PAGE>

which payment is to be made as specified in Section 1 of this Note, for the
enforcement of any and all obligations under this Note and the Loan Documents;
(f) waive the benefit of all homestead and similar exemptions as to this Note;
(g) except as otherwise provided in Section 15 below, agree that their liability
under this Note shall not be affected or impaired by any determination that any
security interest or lien taken by Lender to secure this Note is invalid or
unperfected; and (h) hereby subordinate any and all rights against Borrower and
any of the security for the payment of this Note, whether by subrogation,
agreement or otherwise, until this Note is paid in full. A determination that
any provision of this Note is unenforceable or invalid shall not affect the
enforceability or validity of any other provision and the determination that the
application of any provision of this Note to any person or circumstance is
illegal or unenforceable shall not affect the enforceability or validity of such
provision as it may apply to other persons or circumstances. This Note and the
other Loan Documents may not be amended (i) except in a writing specifically
intended for such purpose and executed by the party against whom enforcement of
the amendment is sought, and (ii) without the written consent of the Required
Lenders, as defined in the Syndicated Credit Agreement. Lender is hereby
authorized to disseminate any information it now has or hereafter obtains
pertaining to the Loan, including, without limitation, any security for this
Note and credit or other information on Borrower, any of its principals and any
guarantor of this Note, to any actual or prospective assignee or participant
with respect to the Loan, to any of Lender's affiliates, to any regulatory body
having jurisdiction over Lender, and to any other parties as necessary or
appropriate in Lender's reasonable judgment, as further provided in the Loan
Agreement. Captions and headings in this Note are for convenience only and shall
be disregarded in construing it. THIS NOTE, AND ITS VALIDITY, ENFORCEMENT AND
INTERPRETATION, SHALL BE GOVERNED BY VIRGINIA LAW (WITHOUT REGARD TO ANY
CONFLICT OF LAWS PRINCIPLES) AND APPLICABLE UNITED STATES FEDERAL LAW.

     14. Notices; Time. All notices, requests, consents, approvals or demands
(collectively, "Notice") required or permitted by this Note to be given by any
party to any other party hereunder shall, unless specified otherwise, be in
writing (including facsimile (fax) transmission) and shall be given to such
party at its address or fax number set forth on the signature pages hereof, or
such other address or fax number as such party may hereafter specify for the
purpose by Notice to the other party. Each such Notice shall be effective when
actually received by the addressee or when the attempted initial delivery is
refused or when it cannot be made because of a change of address of which the
sending party has not been notified; provided, that notices to Lender under
Section 14 hereof, and notices of changed address or fax number, shall not be
effective until received. Whenever a time of day is referred to herein, unless
otherwise specified such time shall be the local time in the city in which this
Note is payable.

     15. Nonrecourse Obligations. Notwithstanding anything contained herein or
in the other Loan Documents to the contrary, the obligations of Borrower under
the Loan Documents are and shall be nonrecourse obligations, and Lender shall
look only to the Property (and the rents and profits therefrom) to recover all
amounts (including, without limitation principal and interest) owing and
outstanding under this Note, the Loan Documents and other documents executed in
connection herewith, and Lender shall not be entitled to enforce or to attempt
to enforce any deficiency or other money judgment against Borrower or any
property of Borrower (other than the Property) with respect to obligations under
the Loan Documents; provided, however, that such limitation of liability shall
not preclude Borrower from being named as a defendant in any suit seeking
specific performance or in connection with the realization of any other remedy
available to Lender (other than obtaining

                                      -8-

<PAGE>

a deficiency or other personal money judgment against Borrower). The foregoing
limitation on Borrower's personal liability with respect to principal and
interest shall not impair the validity of the indebtedness evidenced hereby or
the lien upon or security interest of Lender in the Property or the right of
Lender as mortgagee or secured party to foreclose and/or enforce its rights and
remedies against the Property after an Event of Default. Nothing herein shall be
deemed to be a waiver of any right which Lender may have under Sections 506(a),
506(b), 1111(b) or any other provision of the Bankruptcy Reform Act of 1978 (the
"Code") in any proceeding thereunder to file a claim for the full amount of the
debt owing to Lender by Borrower or to require that all the Property shall
continue to secure all of the indebtedness owing to Lender in accordance with
the Loan Documents. If any portion of any principal or interest outstanding
hereunder or any obligations incurred by Borrower in connection herewith is
determined to be an unsecured claim in any proceeding, Lender agrees that any
such claim shall be subordinated in right of payment to any claims of Banks in
connection with Syndicated Credit Agreement.

     THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND
MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

     THERE ARE NO ORAL AGREEMENTS BETWEEN THE PARTIES.

     Grantor also hereby irrevocably assigns and conveys unto Noteholder, and
grants Noteholder a security interest in, all leases now or hereafter existing
on any part of the Property and any guaranties thereof and all rents from the
Property to secure the payment of all obligations secured hereunder. Grantor
hereby irrevocably appoints Noteholder as its attorney-in-fact to do all things
which Grantor might otherwise do with respect to the Property and the leases
thereon, including, without limitation, (i) collecting said rents with or

all obligations secured hereunder, (ii) leasing, in the name of Grantor, the
whole or any part of the Property which may become vacant, and (iii) employing
agents therefor and paying such agents reasonable compensation for their
services; provided, however, that until there be a default under the terms of
the Note or this Deed of Trust, Grantor may continue to collect and enjoy said
rents without accountability to Noteholder. The curing of any default, however,
shall not entitle Grantor to again collect said rents unless consented to in
writing by Noteholder. The powers and rights granted in this paragraph shall be
in addition to the other remedies herein provided for in an Event of Default and
may be exercised independently of or concurrently with any of said remedies.
Nothing in the foregoing shall be construed to impose any obligation upon
Noteholder to exercise any power or right granted in this paragraph or to assume
any liability under any lease of any part of the Property and no liability shall
attach to Noteholder for failure or inability to collect any rents under any
such lease. Grantor covenants and warrants that (i) it will comply with all
terms and conditions of all leases now existing or that may hereafter come into
existence in respect of the Property or any part thereof; (ii) all leases with
respect to the Property now or hereafter in effect are and shall be valid and
subsisting leases; (iii) it has not sold, assigned, transferred, mortgaged or
pledged, and will not sell, assign, transfer, mortgage or pledge, without
Noteholder's prior written consent, the rents, issues or profits from the
Property and leases thereof to any firm, person or corporation other than
Noteholder; (iv) no rents, issues or profits derived from the Property and
leases, and becoming due subsequent to the date hereof, have been collected or
anticipated in advance of their due date by more than 30 days; (v) it will not
reduce the rental due under any lease of all or any part of the Property without
Noteholder's prior written consent; and (vi) upon request of Noteholder, it will
serve such written notice upon the tenant(s) under such leases or occupant(s) of
the Property or any part thereof, it will execute and deliver to Noteholder such
other instruments or documents reasonably requested by Noteholder for the
purpose of securing or exercising its rights herein and it will provide
Noteholder with true copies or originals of such leases and all amendments,
supplements, renewal or correspondence related thereto.

     So long as no "Event of Default" (hereinafter defined) exists under this
Deed of Trust, Grantor shall remain in quiet use, possession and management of
the Property, and in the enjoyment of the income, revenue and profits therefrom.

     So long as any part of the indebtedness hereby secured remains unpaid,
Grantor covenants and agrees as follows:

1.   Taxes and Assessments. Grantor will pay, promptly when due, all taxes,
assessments and public charges upon the Property, and immediately upon receipt
will forward to Noteholder official receipts evidencing such payments; or in the
alternative and at the option of Noteholder, exercisable at any time after the
occurrence of an Event of Default, will deposit with Noteholder,

                                      -3-

<PAGE>

at such time or times as Noteholder directs, such amounts as are necessary, in
the sole discretion of Noteholder, to enable Noteholder to make timely payment
of such taxes, assessments and charges. Such amounts so deposited shall bear no
interest and may be commingled with other funds held by Noteholder.

2.   Insurance. Grantor will maintain fire insurance, with extended coverage,
and such other insurance as Noteholder may from time to time require, on the
Property, with such insurance companies and in such amounts as shall, at all
times, be satisfactory to Noteholder, with loss payable to Noteholder or
Trustee, as Noteholder shall direct, without contribution; and will deliver to
Noteholder the original policy or policies, and, at least ten days before the
expiration of any policy, the renewal thereof. Noteholder shall have the right,
exercisable at any time after the occurrence of an Event of Default, to require
Grantor to deposit with Noteholder, at such time or times as Noteholder directs,
such amounts as are necessary, in the sole discretion of Noteholder, to enable
Noteholder to make timely payment of the premiums on said policy or policies.
Such amounts so deposited shall bear no interest and may be commingled with
other funds held by Noteholder. As to such insurance, Noteholder may, after ten
days' written notice mailed to Grantor at its last known address, change any or
all of the coverages, terms, amounts or insurers, cause any policy to name
Noteholder as an insured as its interests may appear, surrender existing
policies for cancellation, obtain any cancellation, obtain any additional
insurance it so desires, pay any required premiums and receive premium refunds,
and in any such event any premium adjustment shall be charged against or
credited to the debt secured hereby. In the event any claim for loss covered by
such insurance is not settled within sixty (60) days after the occurrence of
such loss, Noteholder may negotiate with any insurance companies involved and
make a reasonable settlement of said claim, and Noteholder and such insurance
companies, upon such settlement being made, shall not be liable in any manner to
Grantor with respect to such claim and settlement. Any insurance proceeds shall
be applied to the payment of the indebtedness hereby secured (but without any
prepayment penalty) except that if, pursuant to the provisions of the next
paragraph, Noteholder directs Grantor to restore the damaged portion of the
Property, then, to the extent necessary, such proceeds shall (but only to the
extent necessary) be applied to the cost of such restoration, and Noteholder may
without paying interest thereon, retain all or any part thereof until the
Property has been restored to the satisfaction of Noteholder.

3.   Preservation and Maintenance of Property. Grantor will keep the Property
(including any private roads on or over which Grantor has an easement or right
appurtenant to the Property) in good order and repair, including the making of
such replacements as may be necessary for that purpose and, if Noteholder so
directs, the prompt restoration of any part of the Property which may be damaged
by fire or other casualty, irrespective of the availability of adequate
insurance proceeds for that purpose.

4.   Waste. Grantor will not permit, suffer or commit any waste, impairment or
deterioration of, nor allow any nuisance to exist upon, the Property or any part
thereof.

5.   Assurances of Title. Grantor will execute, or cause to be executed, such
further assurances of title to the Property, and will take, and cause to be
taken, such steps, including legal proceedings, as may at any time appear to
Trustee, or to Noteholder, to be desirable to perfect the title to the Property
in Trustee.

                                      -4-

<PAGE>

6.   Books and Records. Grantor will keep and maintain at its principal place of
business complete and accurate books and records of its earnings and expenses of
the Property and copies of all written contracts, leases and other instruments
which affect the Property. Such books, records, contracts, leases and other
instruments shall be subject to examination and inspection at any reasonable
time by Noteholder. In addition, Grantor will furnish to Noteholder, (a) within
ninety (90) days after the end of each fiscal year of Grantor, itemized
statements of income and expense of the Property in form satisfactory to
Noteholder, certified by Grantor or if Noteholder shall require, certified by an
independent certified public accountant, and (b) such other financial
information pertaining to Grantor's financial condition or to the Property as
Noteholder may, from time to time, request.

7.   Liens and Encumbrances. Grantor will not, without the prior written consent
of Noteholder, permit or suffer to exist any lien or encumbrance on the
Property, or interest therein (legal or equitable), or any part thereof, either
inferior or superior in right to the lien of this Deed of Trust, other than the
Permitted Exceptions (as defined in the Note).

8.   Waiver of Exemptions. Grantor will not set up or claim the benefit of any
homestead or other exemption of law, or any other law or rule of law intended
for its advantage or protection as an obligor under the Note or this Deed of
Trust or providing for its release or discharge from any liability under the
Note or this Deed of Trust on account of any facts or circumstances other than
full and complete payment of all amounts due hereunder and under the Note, all
of said exemptions and benefits being hereby expressly waived.

9.   Notice of Suits and Proceedings. Grantor will immediately notify Noteholder
by registered or certified mail, return receipt requested, of any taking or
condemnation, or any threatened or pending proceedings for the taking or
condemnation, of any part of the Property under any power of eminent domain; and
in the event that title to, or possession of, the Property or any portion
thereof, is taken or condemned under any power of eminent domain, then Grantor
will (and hereby does) assign, and will forthwith upon receipt pay over, to
Noteholder, the proceeds and consideration resulting from taking or
condemnation, not to exceed the unpaid balance of the indebtedness secured by
this Deed of Trust, said proceeds so paid to be applied, without repayment
premium, to the indebtedness secured hereby.

10.  Transfer of Property or Beneficial Interest in Grantor. Grantor will not,
without the prior written consent of Noteholder, lease, bargain, sell, transfer,
assign or convey the Property, or any portion thereof, or any legal or equitable
interest therein. If Grantor is not a natural person but is a corporation, then
the bargain, sale, transfer or assignment of all or a substantial portion of the
voting stock of Grantor (including, without limitation, transfers resulting from
mergers, consolidations or liquidations) without the prior written consent of
Noteholder shall be deemed to be in contravention of the provisions of the first
sentence of this paragraph 10.

Notice -- The debt secured hereby is subject to call in full or the terms
thereof being modified in the event of sale or conveyance of the property
conveyed.

11.  Use of Property. Grantor will not, without the prior written consent of
Noteholder, (a) change, or permit any changes in, the use for which all or any
part of the Property was intended at the time of the execution of this Deed of
Trust, or (b) initiate or acquiesce in a change in the zoning classification of
the Property.

12.  Protection of Noteholder's Security. In the event (a) Grantor fails to
perform any of its covenants or agreements herein contained, or (b) any action
or proceeding is commenced or threatened which affects the Property or title
thereto or the interest of Trustee or Noteholder therein, including, without
limitation, eminent domain, insolvency, arrangements or proceedings involving a
bankrupt or decedent, then, in any of such events, Noteholder may, at its
option, make such appearances, disburse such sums and take such action as
Noteholder deems necessary, in its sole discretion, to protect its interest,
including, without limitation, (i) the employment of attorneys and disbursement
of attorneys' fees, (ii) the entry upon the Property to make repairs, (iii) the
procurement of insurance as provided in paragraph 2 hereof, and (iv) if the
Property is subject to another Deed of Trust or lien whether inferior or

from the date of the disbursement thereof at the same rate of interest as set
forth in the Note.

13.  Estoppel Certificate. Grantor will, within ten (10) days of being requested
in writing by Noteholder so to do, furnish a written statement to Noteholder,

thereof or the performance of their obligations herein contained.

14.  Environmental Protection. Grantor covenants and agrees as follows:

     (a) Grantor warrants and represents that it has investigated or caused to
be investigated the uses of the Property, in a manner consistent with good
commercial practices, to determine whether activities have been conducted which
might involve the use, manufacturing, storage or disposal of Hazardous Wastes
(as defined herein) or Toxic Substances (as defined herein), and this
investigation has revealed no fact which would indicate that the Property has
been involved in the use, manufacturing, storage or disposal of Hazardous Wastes
or Toxic Substances in any material respect. This investigation has taken into
account, among other factors, (i) commonly known or reasonably ascertainable
information about the Property, and (ii) the obviousness of the presence or

such laws relating to hazardous waste disposal and toxic substances are
collectively referred to herein as "Environmental Laws."

                                      -6-

     (b) Grantor warrants and represents that it has disclosed to Noteholder all
pending or threatened litigation and orders, rulings, notices, permits or
investigations regarding Hazardous Wastes and Toxic Substances on the Property.

liability on Grantor or any other subsequent or former owner of the Property or
the creation of a lien on the Property under any Environmental Laws.

discharge, spillage, use or the discovery of Hazardous Wastes and Toxic
Substances or any other matters relating to the Environmental Laws as they may
affect the Property.

believe there are Hazardous Wastes or Toxic Substances upon the Property,
Noteholder may obtain, at Noteholder's cost, an environmental site assessment or
environmental audit report from a firm acceptable to Noteholder, to assess with
a reasonable degree of certainty (i) the presence of any Hazardous Wastes or
Toxic Substances and (ii) the cost in connection with the abatement, cleanup or
removal of such.

     (f) Grantor agrees that in the event of the presence of any Hazardous
Wastes or Toxic Substances upon the Property, whether or not the same originates
or emanates from the Property, or if Grantor shall fail to comply with any of
the requirements of the Environmental Laws, Noteholder may at its election, but
without the obligation to do so, (i) give such notices, (ii) cause such work to
be performed at the Property or (iii) take any and all other actions as
Noteholder shall deem necessary or advisable in order to abate, remove and clean
up the Hazardous Wastes or Toxic Substances or otherwise cure Grantor's
noncompliance.

     (g) Grantor acknowledges that Noteholder has made certain loans and other
advances secured by this Deed of Trust in reliance upon Grantor's
representations, warranties and covenants in this paragraph 14.

     (i) The passage after the date of this Deed of Trust of any law of the
state in which the Property conveyed herein is located deducting from the value
of the land, for the purposes of taxation, any lien thereon, or providing for,
or changing in any way the laws relating to, the taxation of deeds of trust or
the notes or debts secured by deeds of trust for state or local purposes, or the
manner of the collection of any such taxes, so as to impair the lien of this
Deed of Trust or the security afforded hereunder, unless Grantor is permitted by
law to pay the whole of such tax imposed upon this Deed of Trust and/or the
indebtedness secured hereby (in addition to all other payments required
hereunder) and Grantor pays such tax and agrees to pay and thereafter pay such
tax whenever levied; or

     (j) The passage of any law or the decision of any court rendering or
declaring any of the material covenants and agreements set out in the Note or in
this Deed of Trust to be legally unenforceable, inoperative, void or voidable;

     then, in any of such events, Trustee and Noteholder shall, in addition to
any other rights and remedies provided by law, have the following rights and
remedies, any or more of which shall be exercisable at the option of Noteholder
and without notice to Grantor (except upon the occurrence of an Event of Default
described in Section 15(e) hereof, in which case all obligations secured hereby,
including without limitation the Note and all accrued interest thereon, shall
become immediately due and payable without demand or notice of any kind and
Trustee and

                                      -8-

<PAGE>

Noteholder may exercise any and all rights and remedies described in clauses
(i), (ii) and (iii) of this Section 15, under, if needed, and/or otherwise
available to Trustee and/or Noteholder):

           (i)   Noteholder may declare the Note, and all sums due hereunder,
immediately due and payable without demand;

           (ii)  Noteholder may apply for and obtain the appointment of a
receiver for the Property, with the power to collect the rents, issues and
profits therefrom, without regard to the value of the Property or of the
solvency of any person or persons liable for the payment of the indebtedness
secured hereby, and Grantor hereby waives any and all defenses to the
application for appointment of such receiver and consents to the appointment of
such receiver without notice, but reserves the right to apply for vacation of
any order of appointment of such receiver, or for any other appropriate relief,
upon showing that none of the foregoing events of default occurred prior to
application for the appointment of such receiver or during the pendency of such
application in court; and

           (iii) Trustee may foreclose by a sale of the Property as follows:

                 (A) Trustee may take possession of the Property and proceed to

     corporate limits of any city surrounded by or contiguous to such county, or
     in the case of annexed land, in the county of which the land was formerly a
     part, as Trustee may select upon such terms and conditions as Trustee may
     deem best, after first advertising the time, place and terms of sale once a
     week for two consecutive weeks, in advance of the date of such sale, in the
     legal notice section of a newspaper published or having general circulation
     in the county or city in which the Property or some portion thereof is
     located.

                 (B) The power of sale above granted may be exercised at
     different times as to different portions of the Property, and if for any
     reason any executory contract of sale shall not be performed, then new
     contracts may be made with respect to the same portion of the Property
     (with or without other portions). If Trustee deems it best for any reason
     to postpone or continue the sale at any time or from time to time, they may
     do so, in which event Trustee shall advertise the postponed sale in the
     same manner as the original advertisement of sale provided for in clause
     (A) above.

                 (C) Full power and authority is hereby expressly granted and
     conferred upon Trustee to make, execute, and deliver all necessary deeds of
     conveyance for the purpose of vesting in the purchaser or purchasers
     complete and entire legal and equitable title to the Property, or the
     portion thereof so sold, and the recitals therein stated; and at such sale
     Noteholder may become a purchaser, and no purchaser shall be required to
     see to the proper application of the purchase money.

                 (D) The proceeds of such sale shall be applied, first, to
     discharge the expenses of executing the trust, including a commission to
     Trustee of five percent (5%) of the gross proceeds of sale; next, to

     interest, including a proper proration thereof for the current year; next,
     to reimburse Trustee and Noteholder for all sums expended by them pursuant
     to the

                                      -9-

     provisions of this Deed of Trust, with interest thereon; next, to pay the
     accrued interest on the unpaid principal balance due under the Note; next,
     to pay said unpaid principal balance; next, to pay any indebtedness secured
     by any lien of record inferior to the lien of this Deed of Trust; and any
     residue of said proceeds shall be paid to Grantor provided, however, that
     Trustee as to such residue shall not be bound by any inheritance, devise,
     conveyance, assignment or lien of or upon Grantor's equity, without actual
     notice thereof prior to distribution.

a secured party, lienholder or creditor with respect to any fixtures mentioned
in such financing statement. Grantor shall pay all costs of filing such
financing statement and any extensions, renewals, amendments and releases
thereof, and shall pay all costs and expenses (including legal fees) of any
record searches for financing statements Noteholder may reasonably require.
Without the prior written consent of Noteholder, Grantor shall not create, or
suffer to be created pursuant to the Uniform Commercial Code any other security
interest in said fixtures, including replacements and additions thereto. In the
event of a default of any covenant or agreement of Grantor contained in this
Deed of Trust, Noteholder shall, in addition to all other rights and remedies
herein provided, have all the remedies accorded a secured party under the
Uniform Commercial Code.

17.  Non Waiver. No delay, act or failure to act, by Trustee and Noteholder, or
any of them, however long continued, shall be construed as a waiver of any of
their rights hereunder or of any default by Grantor.

18.  No Liability of Obligation on Trustee or Noteholder. Nothing in this Deed
of Trust shall be construed to impose any obligation upon either Noteholder or
Trustee to expend any money or to take any other discretionary act herein
permitted, and neither Noteholder nor Trustee shall have any liability or
obligation for any delay or failure to take any discretionary act. Trustee shall
not be required to see that this Deed of Trust is recorded and shall not be
liable for the default or misconduct of any agent or attorney appointed by them
in pursuance hereof, or for anything whatever in connection with this trust,
except willful misconduct or gross negligence. Trustee may act upon any
instrument or paper believed by them in good faith to be genuine and to be
signed by the proper party or parties, and shall be fully protected for any
action taken or suffered by them in reliance thereon.

19.  Release Upon Full Payment. Upon full payment of all sums due under the Note
and this Deed of Trust, Trustee shall, upon the request of, and at the cost of,
Grantor, execute a proper release of this Deed of Trust.

20.  Any Trustee May Act and Substitution of Trustee. Notwithstanding anything
herein contained to the contrary, (a) any one or more of Trustees may act
hereunder without the joinder of any other Trustee or Trustees and without the
joinder of Noteholder, and any act taken hereunder by any one or more of
Trustees shall be as effective as if taken by all Trustees, (b) the fact that
one or more but less than all of Trustees take any action hereunder shall not
preclude all Trustees or any one or more of the other Trustees from taking any
other action hereunder, (c) the fact that all Trustees join in any act hereunder
shall not preclude less than all Trustees taking any other action hereunder, and
(d) if any one or more Trustees fail, refuse, or become unable to act,

                                      -10-

<PAGE>

or if for any reason Noteholder, in its absolute discretion, deems it advisable,
Noteholder is hereby authorized and empowered to appoint, by an instrument
recorded wherever this Deed of Trust is recorded, one or more other Trustees, in
the place and stead of Trustee herein named, which Substitute Trustee or
Trustees shall have all rights, powers, and authority and be charged with all
the duties that are conferred or charged upon Trustee herein named.

21.  Advances and Future Advances. It is understood and agreed that the proceeds
of the indebtedness evidenced by the Note may be advanced by Noteholder at one
time, or from time to time, and Noteholder reserves the right to make additional
advances of proceeds, from time to time, including the readvance of any sums
previously repaid on the Note, provided, and so long as, the unpaid principal
balance of the Note, including the additional advances or readvances of
proceeds, does not exceed the original principal amount of the Note. In the
event of the readvance by Noteholder of any sums previously repaid on the Note,
then, in such event, the Note shall be deemed to evidence, and this Deed of
Trust shall be deemed to secure the repayment of, the proceeds last advanced
under the Note by Noteholder.

22.  Indemnification by Grantor. Grantor shall protect and indemnify Trustee
from and against all liabilities, obligations, claims, damages, penalties,
causes of action, costs and expenses (including, without limitation, reasonable
attorneys' fees and disbursements), imposed upon or incurred by or asserted
against Trustee by reason of (a) ownership of the Property or any interest
therein, or receipt of any rent or other sum therefrom, (b) any accident to,
injury to or death of persons or loss or damage to property occurring on or
about the Property or the adjoining sidewalks, curbs, vaults or vault space, if
any, streets or ways, (c) any use, non-use or condition of the Property or the
adjoining sidewalks, curbs, vaults or vault space, if any, streets or ways, (d)
any failure on the part of Grantor to perform or comply with any of the terms,
covenants, conditions and agreements set forth in this Deed of Trust, the Note,
or other agreements executed by Grantor for the benefit of Noteholder, (e)
performance of any labor or service or the furnishing of any materials or other
property in respect of the Property or any part thereof for construction or
maintenance or otherwise, (f) any action brought against Trustee attacking the
validity, priority or enforceability of this Deed of Trust, the Note, or any
other agreements executed by Grantor for the benefit of Noteholder, and/or (g)
the presence of Hazardous Wastes (as defined herein) or Toxic Substances (as
defined herein) on the Property. Any amounts payable to Trustee under this
paragraph 22 which are not paid within ten (10) days after written demand
therefor by Trustee shall bear interest as provided in the Note and shall be
secured by this Deed of Trust. In the event any action, suit or proceeding is
brought against Trustee, Grantor, upon the request of Trustee and at Grantor's
expense, shall resist and defend such action, suit or proceeding or cause the
same to be resisted and defended by counsel designated by Grantor and approved
by Trustee. Such obligations under this paragraph 22 shall survive the
termination, satisfaction or release of this Deed of Trust.

23.  Waiver of Notice of Future Advances and Consent to Extensions,
Modifications and Release. If Grantor is not the maker of the Note, then Grantor
expressly (i) waives notice of any and all loans and/or advances made, from time
to time during the continuance of this Deed of Trust, by Noteholder to the maker
of the Note; (ii) agrees that the terms of the Note, including, without
limitation, modifications extending the term for payment and adjusting the
interest rate, may be made from time to time between Noteholder and the maker of
the Note without notice to or further consent of Grantor; (iii) agrees that
Noteholder, without notice to or further consent of

                                      -11-

<PAGE>

Grantor, may grant extensions of time and other indulgences to and renew any of
the obligations of (without regard to the number and length of such extensions,
renewals or other indulgences) the maker of the Note or any other person liable
thereon; and (iv) waives any rights it may have under Virginia Code Sections
49-25 and 49-26, with respect to the Note. Grantor further agrees that
Noteholder, without notice to or further consent of Grantor, may release or
discharge any persons who are or may become liable for the payment of the Note
or release or discharge any other collateral for the payment of the Note and
that any such release or discharge shall not alter, modify, release or limit the
liability of Grantor (or any of them) hereunder or the validity and
enforceability of this Deed of Trust.

24.  Headings. The headings of the paragraphs of this Deed of Trust are for the
convenience of reference only and are not to be considered a part hereof and
shall not limit or otherwise affect any of the terms hereof.

25.  Number and Gender. The pronouns and verbs set forth herein shall be

Instrument prepared by:
E. Kristen Moye, Esquire
McGuireWoods LLP
1750 Tysons Boulevard, Suite 1800
McLean, Virginia 22102

Note to Clerk: This Assignment of Leases, Rents and Profits provides additional
security for certain obligations of the Borrower on which recordation tax has
been previously paid. Pursuant to Va. Code (S)58.1807(C), this instrument is not
subject to additional tax.


                     ASSIGNMENT OF LEASES, RENTS AND PROFITS

     THIS ASSIGNMENT OF LEASES, RENTS AND PROFITS, made this 31/st/ day of
January, 2002, from ETHYL CORPORATION, a Virginia corporation ("Borrower"),
grantor for indexing purposes, to the BRUCE C. GOTTWALD, SR., an individual
("Lender"), grantee for indexing purposes;

     WHEREAS, Lender has made a loan to Borrower (the "Loan"), which Loan is to
be evidenced by that certain Deed of Trust Note (the "Note") of Borrower, of
even date herewith, payable to Lender in the principal amount of EIGHTEEN
MILLION SIX HUNDRED FORTY THOUSAND AND NO/100 DOLLARS ($18,640,000.00) and
secured by a deed of trust dated of even date herewith (the "Deed of Trust") on
the Property described in SCHEDULE A attached hereto (the "Property"); and

     WHEREAS, as a condition precedent to making the Loan, Lender has required
an assignment by Borrower of all leases, rents, issues, profits, revenues,
rights and benefits now or hereafter arising from the Property, pursuant to the
terms and conditions set forth herein.

     NOW, THEREFORE, for and in consideration of the agreement of Lender to make
the Loan to Borrower, Lender and Borrower agree as follows:

1.   Assignment.

     (A) Borrower hereby absolutely and irrevocably assigns, transfers and
conveys to Lender, all the right, title and interest of Borrower in and to all
rents, profits, security deposits, damage claims and awards now due or hereafter
to become due, or arising (collectively the "Rents") from the Property and the
Leases. To that end Borrower also irrevocably assigns, transfers and sets over
to Lender all the right, title and interest of Borrower in all existing and
future leases, licenses and other agreements between Borrower and any other
party relating to the occupancy of the Property, or any part thereof, whether
written or verbal, including, without limitation, the leases described in
SCHEDULE B attached hereto and made a part hereof (the "Leases"). The term
"Leases" shall include all amendments, renewals and extensions thereof and all
guaranties of the lessee's performance thereunder. Borrower hereby irrevocably
appoints Lender as its attorney-in-fact to do all things which Borrower might
otherwise do with respect to

                                       -1-

<PAGE>

the Rents, Leases and the Property, including, without limitation, those acts
specified in paragraph 2 hereof.

     (B) Borrower further assigns, transfers and sets over to Lender all of
Borrower's right, title and interest in and to all claims and rights to the
payment of money at any time arising in connection with any rejection or breach
of any of the Leases by any lessee thereunder or trustee of any such lessee
under Section 365 of the Bankruptcy Code, 11 U.S.C. (S) 365, including, without
limitation, all rights to recover damages arising out of such breach or
rejection, all rights to charges payable by such lessee or trustee in respect of
the leased premises following the entry of any order for relief under the
Bankruptcy Code in respect of such lessee, and all rentals and other charges
outstanding under the Leases as of the date of entry of such order for relief.

     (C) If Borrower shall receive on account of any claim, demand, action, suit
or proceeding, including, without limitation, any claim, contested matter, or
adversary proceeding under the Bankruptcy Code, 11 U.S.C. (S)101, et seq., any
sums relating to the breach or rejection of any of the Leases by any lessee
thereunder or trustee of any such lessee under Section 365 of the Bankruptcy
Code, 11 U.S.C. (S)365, including, without limitation, all damages arising out
of such breach or rejection, all rights to charges payable by such lessee or
trustee in respect of the premises demised under such Lease(s) following the
entry of any order for relief under the Bankruptcy Code in respect of such
lessee and all rentals and other charges outstanding under the Lease(s) as of
the date of entry of such order for relief, the Borrower shall promptly deposit
such sums in a segregated account (the "Account") maintained with Lender, and
shall cause the Account to be designated on the records of the Lender as
collateral for the payment and performance of the Loan. Borrower hereby assigns,
transfers and sets over to Lender, and grants to Lender a security interest in,
all sums in the Account as further security for the payment and performance of
the Loan.

Borrower shall not withdraw any sums or further encumber the Account without the
Lender's prior written consent so long as the Loan shall remain outstanding,
provided, however, that if there shall not have occurred and be continuing any
Event of Default or event, which with the giving of notice or lapse of time, or
both, would constitute an Event of Default, the Account shall be released to the
Borrower free of the lien and security interest granted hereby on the earlier of
(a) full and final payment of the Loan or upon a "Qualified Transfer" (as
defined in the Note), or (b) the date on which Borrower shall have entered into
a new Lease on terms and conditions approved by Lender and the new lessee
thereunder has taken possession of the demised premises and commenced the
payment of rent thereunder.

2.   Borrower's License. So long as no Event of Default has occurred under the
Note, the Deed of Trust, any document relating thereto or arising therefrom, any
collateral security documents with respect to the Loan, or this Assignment,
Borrower shall have a license to manage and operate the Property and collect,
receive and apply, for its own account, all Rents arising from the Property as
they become due, but are not more than thirty (30) days in advance.

3.   Remedies on Default.

     (a) In the event an Event of Default occurs under the Note, the Deed of
Trust, any document relating hereto or arising therefrom, any collateral
security documents relating to the

                                       -2-

<PAGE>

Loan, or this Assignment, the license granted in paragraph 2 above shall
automatically, without further act by Lender, cease and terminate. In any such
event Lender is hereby expressly and irrevocably authorized, at its opinion, to
enter and take possession of the Property by actual physical possession or by
written notice served personally upon or sent by registered or certified mail to
Borrower, as Lender may elect, and no further authorization shall be required.
Prior to, or upon such entry and taking possession, Lender, in its sole and
absolute discretion, may:

         (1) manage and operate the Property or any part thereof including the
making of such repairs and alterations to the Property as Lender may deem
necessary;

         (2) demand, collect, receive, sue for, attach, levy, recover,
compromise and adjust, and to give proper receipts and releases for all Rents
that may then be due or may thereafter become due with respect to the Property,
or any part thereof, from any present or future lessees, sublessees or occupants
thereof;

         (3) lease the Property, or any part hereof, in the name of the
Borrower, for such periods of time, and upon such terms and conditions as Lender
may deem proper;

         (4) enforce, cancel or modify any Lease, including the taking of any
action necessary to enforce, enjoin or restrain the violation of any of the
terms and conditions of any Lease;

         (5) institute, prosecute to completion or compromise and settle, all
summary proceeding, actions for Rent or for removing any and all lessees,
sublessees or occupants of the Property, or any part thereof;

         (6) pay out of the Rents, or out of any other funds in its discretion,
the rent and all charges required to be paid under any ground lease of the
Property, any taxes, assessments, water rates, sewer rates, or other
governmental charges levied, assessed or imposed against the Property, or any
part thereof, and also any and all other charges, costs and expenses which it
may deem necessary or advisable for Lender to pay in the management or operation
of the Property and legal expenses incurred in enforcing the rights of Lender
under the Note, the Deed of Trust, any document relating thereto or arising
therefrom, any collateral security documents and this Assignment;

         (7) generally do, execute and perform any other acts which, in Lender's
sole discretion, are necessary or advisable in and about or with respect to the
Property as fully as Borrower might do; and

         (8) employ agents to perform any of the foregoing and to pay such
agents reasonable compensation for their services.

     (b) Lender shall apply the net amount of any Rents received by it from the
Property, after payment of all costs and charges, including, without limitation,
any sums due under the Note, the Deed of Trust or any collateral security
document, to the payment of its fees and expenses incurred, the accrued interest
and other charges due on the Note and the balance, if any, to the principal of
the Note. Lender shall account to Borrower only for Rents actually received by
Lender pursuant to this Assignment.

                                       -3-

<PAGE>

4.   Notice to Lessees. Borrower hereby irrevocably directs any lessee under any
Lease, upon demand and notice from the Lender of the occurrence of an Event of
Default under the Note, the Deed of Trust, any document relating thereto or
arising therefrom, any collateral security documents or this Assignment, to pay
to Lender all Rents accruing or due under any Lease from and after the receipt
of such demand and notice. In making such payments, such lessee shall be under
no obligation to inquire into or determine the actual existence of any such
Event of Default claimed by Lender.

5.   Indemnity. Borrower agrees to indemnify and hold Lender harmless from and
against any and all liability, loss, damage or expense, including reasonable
attorney's fees, which it may incur under any Lease or by reason of this
Assignment, or by reason of any action taken by Lender or Borrower hereunder,
and from and against any and all claims and demands whatsoever which may be
asserted against Lender by reason of any alleged obligation or undertaking on
its part to perform or discharge any of the terms, conditions and covenants
contained in any of the Leases. Should Lender incur any such liability, loss,
damage, or expense, the amount thereof, together with interest thereon at the
rate set forth in the Note in respect of default, shall be payable by Borrower
to Lender solely out of any Rents collected by Lender and the Property.

6.   Borrower's Warranties. Borrower represents and warrants:

     (a) that Borrower (i) is the owner in fee simple of the Property, (ii) has
good title to, and the right to assign the Leases and Rents, and (iii) that no
other person, firm, corporation or entity has any superior rights, title or
interest therein;

     (b) that Borrower is not in default under the Leases and that the Leases
are valid and unmodified except as indicated herein; and

     (c) that there has been no anticipation or prepayment of Rents for more
than thirty (30) days under any of the Leases, and that Borrower has not waived,
released, discounted or otherwise discharged or compromised any Rents due after
the date hereof.

7.   Borrower's Covenants. Borrower covenants and agrees:

     (a) to duly and punctually perform all the terms, conditions and covenants
of any Leases on Borrower's part to be kept, observed and performed;

     (b) to enforce or secure the performance of all terms, conditions and
covenants of the Leases to be kept, observed and performed by lessees
thereunder;

     (c) to execute and deliver to Lender such further instruments as Lender may
deem necessary, from time to time, to make effective the Assignment and
covenants contained herein;

     (d) not to sell, assign, transfer or pledge any of the Rents or Leases
arising from the Property, whether now due or hereafter to become due;

     (e) not to receive or collect any Rents from any present or future lessee
under any Lease for a period of more than one month in advance;

                                       -4-

<PAGE>

     (f) not to waive, set-off, compromise, or in any manner release or
discharge any lessee under any Lease of and from any terms, conditions, and
covenants to be kept, observed and performed by said lessee, including the
obligation to pay Rent;

     (g) except as may otherwise by expressly permitted by the terms of any
existing Lease, not to cancel, terminate or consent to any surrender of any
Lease, nor modify or amend any of the terms thereof, nor consent to the
subletting of the Property, or any part thereof, or the assignment of any Lease
by the lessee thereunder without the prior written consent of Lender;

     (h) to serve such written notice upon the lessee(s) under the Leases or
occupants of the Property as shall be requested by Lender, and to execute and
deliver to Lender such other instruments or documents reasonably requested by
Lender, for the purpose of securing, perfecting or exercising Lender's rights
herein; and

     (i) upon the occurrence of an Event of Default under the Note or the Deed
of Trust, surrender and deliver to Lender the originals of the Leases and all
records or pertinent correspondence relating thereto.

8.   No Obligations on Lender. Nothing contained herein shall operate or be
construed to obligate Lender to perform any of the terms, covenants and
conditions contained in any Lease of or relating to the Property or otherwise to
impose any obligation upon Lender with respect to any Lease of the Property,
including, but not limited to, any obligation arising out of any covenant of
quiet enjoyment therein contained in the event the lessee shall have been
thereby terminated. Prior to actual entry into and taking possession of the
Property by Lender, this Assignment shall not operate to place upon Lender any
responsibility for the operation, control, care, management or repair of the
Property, and the execution of this Assignment by Borrower shall constitute
conclusive evidence that all responsibility for the operation, control, care,
management and repair of the Property is and shall be that of Borrower, prior to
such actual entry and taking possession.

9.   No Merger. As against Lender, at all times during which this Assignment
shall be in effect, there shall be no merger of any Leases of the Property with
the fee estate in the Property by reason of the fact that any such Leases or any
interest therein may be held by or for the account of any person, firm or
corporation which may be or become the owner of such fee estate, unless Lender
shall consent in writing to such merger.

10.  Cumulative Rights and No Waiver. The rights granted Lender under this
Assignment, the Note, the Deed of Trust, or any document relating thereto or
arising therefrom, or any other collateral security documents, or permitted at
law or in equity, shall be cumulative and may be exercised at any time and from
time to time. No failure or delay on the part of Lender to exercise any rights
hereunder shall be construed or deemed to be a waiver thereof, nor shall any
single or partial exercise by Lender of any right preclude any other future
exercise thereof or the exercise of any other right.

11.  Assignment. Lender shall have the right to assign to any subsequent
permitted holder of the Note, the right, title and interest of Borrower hereby
assigned, subject, however, to the terms of this Assignment. In the event all
right, title and interest of Borrower in the Property are barred

                                       -5-

<PAGE>

or foreclosed, no assignee of Borrower's interest shall be liable to account to
Borrower for any Rents thereafter accruing.

12.  Miscellaneous.

     (a) No amendment, modification, cancellation or discharge hereof shall be
valid unless (i) Lender consents thereto in writing, and (ii) the Required Banks
(as defined in the Syndicated Credit Agreement) provide their written consent
thereto.

     (b) This Assignment and all the terms, covenants and conditions contained
herein shall be binding upon Borrower, its successors, assigns, heirs and
personal and legal representatives, as the case may be, and every term, covenant
and condition herein reserved or secured to Lender shall inure to the benefit of
Lender's successors and assigns.

     (c) The titles to each paragraph hereof are for convenience only, and shall
not be considered or referred to in resolving questions or interpretation or
construction.

     (d) This Agreement shall be governed by and interpreted in accordance with
the laws of the Commonwealth of Virginia.

     (e) Notwithstanding anything contained herein to the contrary, the
obligations of the Borrower evidenced by the Note, the Deed of Trust, this
Assignment and any other documents executed in connection herewith are
non-recourse to the Borrower.
