                          EMPLOYEE STOCK PURCHASE PLAN

1.  PURPOSE.

    Company and certain designated Affiliates may be given an opportunity to
    purchase Shares of the Company.

    Employees, to secure and retain the services of new Employees and to provide
    incentives for such persons to exert maximum efforts for the success of the
    Company and its Affiliates.

(d) The Company intends that the Rights to purchase Shares granted under the
    Plan be considered options issued under an "employee stock purchase plan,"

(a) The Board shall administer the Plan unless and until the Board delegates
    administration to a Committee, as provided in subsection 3(c). Whether or
    not the Board has delegated administration, the Board shall have the final
    power to determine all questions of administration, interpretation, policy
    or expediency that may arise in the administration of the Plan.

(b) The Board (or the Committee) shall have the power, subject to, and within
    the limitations of, the express provisions of the Plan:

    (i)   To determine when and how Rights to purchase Shares shall be granted
          and the provisions of each Offering of such Rights (which need not be
          identical).

    (ii)  To designate from time to time which Affiliates of the Company shall
          be eligible to participate in the Plan.

    (iii) To construe and interpret the Plan and Rights granted under it, and to
          establish, amend and revoke rules and regulations for its
          administration. The Board, in the exercise of this power, may correct
          any defect, omission or inconsistency in the Plan, in a manner and to
          the extent it shall deem necessary or expedient to make the Plan fully
          effective.

    (iv)  To amend the Plan as provided in Section 15.

    (v)   Generally, to exercise such powers and to perform such acts as it
          deems necessary or expedient to promote the best interests of the
          Company and its Affiliates and to carry out the intent that the Plan
          be treated as an Employee Stock Purchase Plan.

(c) The Board may delegate administration of the Plan to a Committee of the
    Board composed of two (2) or more members. In the absence of such action,
    all references in this Plan to the Committee shall be deemed to refer to the
    Board. If administration is delegated to a Committee, the Committee shall
    have, in connection with the
<PAGE>

    administration of the Plan, the powers theretofore possessed by the Board,
    including the power to delegate to a subcommittee of one (1) or more
    Directors any of the administrative powers the Committee is authorized to
    exercise (and references in this Plan to the Board shall thereafter be to
    the Committee or such a subcommittee), subject, however, to such
    resolutions, not inconsistent with the provisions of the Plan, as may be
    adopted from time to time by the Board. The Board may abolish the Committee
    at any time and revest in the Board the administration of the Plan.

4.  SHARES SUBJECT TO THE PLAN.

(a) Subject to the provisions of Section 14 relating to adjustments upon changes
    in securities, the Shares that may be sold pursuant to Rights granted under
    the Plan shall not exceed in the aggregate Five Hundred and Twenty-Five
    Thousand (525,000) Shares. If any Right granted under the Plan shall for any
    reason terminate without having been exercised, the Shares not purchased
    under such Right shall again become available for the Plan.

(b) The Shares subject to the Plan may be unissued Shares or Shares that have
    been bought on the open market at prevailing market prices or otherwise.

5.  GRANT OF RIGHTS; OFFERING.

(a) The Committee may from time to time grant or provide for the grant of Rights
    to purchase Shares of the Company under the Plan to Eligible Employees in an
    Offering on one or more Offering Dates selected by the Committee. Each
    Offering shall be in such form and shall contain such terms and conditions
    as the Committee shall deem appropriate, which shall be designed to comply
    with the requirements of Section 423(b)(5) of the Code that all Employees
    granted Rights to purchase Shares under the Plan shall have the same rights
    and privileges. The terms and conditions of an Offering shall be
    incorporated by reference into the Plan and treated as part of the Plan. The
    provisions of separate Offerings need not be identical, but each Offering
    shall include (through incorporation of the provisions of this Plan by
    reference in the Offering Memorandum or otherwise) the period during which
    the Offering shall be effective, which period shall not exceed twenty-seven
    (27) months beginning with the Offering Date, and the substance of the
    provisions contained in Sections 6 through 9, inclusive.

(b) If a Participant has more than one Right outstanding under the Plan, unless
    he or she otherwise indicates in agreements or notices delivered hereunder:
    (i) each agreement or notice delivered by that Participant will be deemed to
    apply to all of his or her Rights under the Plan, and (ii) an earlier-
    granted Right (or a Right with a lower exercise price, if two Rights have
    identical grant dates) will be exercised to the fullest possible extent
    before a later-granted Right (or a Right with a higher exercise price if two
    Rights have identical grant dates) will be exercised.

6.  ELIGIBILITY.

(a) Rights may be granted only to Employees of the Company or, as the Committee
    may designate as provided in subsection 3(b), to Employees of an Affiliate
    designated by the Board. Except as provided in subsection 6(b), an Employee
    shall not be eligible to be granted Rights under the Plan unless, on the
    Offering Date, such Employee has been in the employ of the Company or the
    Affiliate, as the case may be, for such continuous period preceding such
    grant as the Board may require, if any, but in no event shall the required
    period of continuous employment be equal to or greater than two (2) years.

(b) The Committee may provide that each person who, during the course of an
    Offering, first becomes an Eligible Employee will, on a date or dates
    specified in the Offering which coincides with the day on which such person
    becomes an Eligible Employee or which occurs thereafter, receive a Right
    under that Offering, which Right shall thereafter be deemed to be a part of
    that Offering. Such Right shall have the same characteristics as any Rights
    originally granted under that Offering, as described herein, except that:
<PAGE>

    (i)   the date on which such Right is granted shall be the "Offering Date"
          of such Right for all purposes, including determination of the
          exercise price of such Right;

    (ii)  the period of the Offering with respect to such Right shall begin on
          its Offering Date and end coincident with the end of such Offering;
          and

    (iii) the Committee may provide that if such person first becomes an
          Eligible Employee within a specified period of time before the end of
          the Offering, he or she will not receive any Right under that
          Offering.

(c) No Employee shall be eligible for the grant of any Rights under the Plan if,
    immediately after any such Rights are granted, such Employee owns stock
    possessing five percent (5%) or more of the total combined voting power or
    value of all classes of stock of the Company or of any Affiliate. For
    purposes of this subsection 6(c), the rules of Section 424(d) of the Code
    shall apply in determining the stock ownership of any Employee, and stock
    which such Employee may purchase under all outstanding rights and options
    shall be treated as stock owned by such Employee.

(d) An Eligible Employee may be granted Rights under the Plan only if such
    Rights, together with any other Rights granted under all Employee Stock
    Purchase Plans of the Company and any Affiliates, as specified by Section
    423(b)(8) of the Code, do not permit such Eligible Employee's rights to
    purchase Shares of the Company or any Affiliate to accrue at a rate which
    exceeds the lesser of (i) twenty five thousand dollars ($25,000) of the fair
    market value of such Shares (determined at the time such Rights are granted)
    for each calendar year in which such Rights are outstanding at any time, and
    (ii) such lower limit as the Committee may establish on a non-discriminatory
    basis.

(e) The Committee may provide in an Offering that Employees who are highly
    compensated employees within the meaning of Section 423(b)(4)(D) of the Code
    shall not be eligible to participate.

7.  RIGHTS; PURCHASE PRICE.

(a) On each Offering Date, each Eligible Employee, pursuant to an Offering made
    under the Plan, shall be granted the Right to purchase up to the number of
    Shares purchasable either:

    (i)   with a percentage designated by the Committee not exceeding fifteen
          percent (15%) of such Employee's Earnings (as defined by the Committee
          in each Offering) during the period which begins on the Offering Date
          (or such later date as the Committee determines for a particular
          Offering) and ends on the date stated in the Offering, which date
          shall be no later than the end of the Offering; or

    (ii)  with a maximum dollar amount designated by the Committee that, as the
          Committee determines for a particular Offering, (1) shall be withheld,
          in whole or in part, from such Employee's Earnings (as defined by the
          Committee in each Offering) during the period which begins on the
          Offering Date (or such later date as the Committee determines for a
          particular Offering) and ends on the date stated in the Offering,
          which date shall be no later than the end of the Offering and/or (2)
          shall be contributed, in whole or in part, by such Employee during
          such period.

(b) The Committee shall establish one or more Purchase Dates during an Offering
    on which Rights granted under the Plan may be exercised and purchases of
    Shares carried out in accordance with such Offering.

(c) In connection with each Offering made under the Plan, the Committee may
    specify a maximum amount of Shares that may be purchased by any Participant
    as well as a maximum aggregate amount of Shares that may be purchased by all
    Participants pursuant to such Offering. In addition, in connection with each
    Offering that contains more than one Purchase Date, the Committee may
    specify a maximum aggregate amount of Shares which may be purchased by all
    Participants on any given Purchase Date under the Offering. If the aggregate
<PAGE>

    purchase of Shares upon exercise of Rights granted under the Offering would
    exceed any such maximum aggregate amount or the amount of Shares then
    available for purchase under the Plan, the Committee shall make a pro rata
    allocation of the Shares available in as nearly a uniform manner as shall be
    practicable and as it shall deem to be equitable.

(d) The purchase price of Shares acquired pursuant to Rights granted under the
    Plan shall be not less than the lesser of:

    (i)   an amount equal to eighty-five percent (85%) of the fair market value
          of the Shares on the Offering Date; or

    (ii)  an amount equal to eighty-five percent (85%) of the fair market value
          of the Shares on the Purchase Date.

8.  PARTICIPATION; WITHDRAWAL; TERMINATION.

(a) An Eligible Employee may become a Participant in the Plan pursuant to an
    Offering by delivering a participation agreement to the Company within the
    time specified in the Offering Memorandum, in such form as the Company
    provides. Each such agreement shall authorize payroll deductions of up to
    the maximum percentage specified by the Committee of such Employee's
    Earnings during the Offering (as defined in each Offering), up to the limit
    set forth in Section 6(d). The payroll deductions made for each Participant
    shall be credited to a bookkeeping account for such Participant under the
    Plan and either may be deposited with the general funds of the Company or
    may be deposited in a separate account in the name of, and for the benefit
    of, such Participant with a financial institution designated by the Company,
    as determined by the Company. To the extent provided in the Offering, a
    Participant may reduce (including to zero) or increase such payroll
    deductions. To the extent provided in the Offering, a Participant may begin
    such payroll deductions after the beginning of the Offering. A Participant
    may make additional payments into his or her account only if specifically
    provided for in the Offering and only if the Participant has not already had
    the maximum permitted amount withheld during the Offering. At no time shall
    a Participant be entitled to interest or accruals of interest on amounts
    credited to his or her account.

(b) At any time during an Offering, a Participant may terminate his or her
    payroll deductions under the Plan and withdraw from the Offering by
    delivering to the Company a notice of withdrawal in such form as the Company
    provides. Such withdrawal may be elected at any time prior to the end of the
    Offering except as provided by the Committee in the Offering. Upon such
    withdrawal from the Offering by a Participant, the Company shall distribute
    to such Participant all of his or her accumulated payroll deductions
    (reduced to the extent, if any, such deductions have been used to acquire
    Shares for the Participant) under the Offering, without interest, and such
    Participant's interest in that Offering shall be automatically terminated.
    Except to the extent specified by the Committee, a Participant's withdrawal
    from an Offering will have no effect upon such Participant's eligibility to
    participate in any other Offerings under the Plan but such Participant will
    be required to deliver a new participation agreement in order to participate
    in subsequent Offerings under the Plan.

(c) Rights granted pursuant to any Offering under the Plan shall terminate
    immediately upon cessation of any participating Employee's employment with
    the Company and its designated Affiliates for any reason (subject to any
    post-employment participation period required by law) or other lack of
    eligibility. The Company shall distribute to such terminated Employee all of
    his or her accumulated payroll deductions (reduced to the extent, if any,
    such deductions have been used to acquire Shares for the terminated
    Employee) under the Offering, without interest. If the accumulated payroll
    deductions have been deposited with the Company's general funds, then the
    distribution shall be made from the general funds of the Company, without
    interest. If the accumulated payroll deductions have been deposited in a
    separate account with a financial institution as provided in subsection
    8(a), then the distribution shall be made from the separate account, without
    interest.

(d) Rights granted under the Plan shall not be transferable by a Participant
    otherwise than by will or the laws of descent and distribution, or by a
    beneficiary designation as provided in Section 16 and, otherwise during his
    or
<PAGE>

    her lifetime, shall be exercisable only by the person to whom such Rights
    are granted.

9.  EXERCISE.

(a) On each Purchase Date specified therefor in the relevant Offering, each
    Participant's accumulated payroll deductions and other additional payments
    specifically provided for in the Offering (without any increase for
    interest) will be applied to the purchase of Shares up to the maximum amount
    of Shares permitted pursuant to the terms of the Plan and the applicable
    Offering, at the purchase price specified in the Offering. No fractional
    Shares shall be issued upon the exercise of Rights granted under the Plan
    unless specifically provided for in the Offering and permitted by law.

(b) Unless otherwise specifically provided in the Offering, the amount, if any,
    of accumulated payroll deductions remaining in any Participant's account
    after the purchase of Shares that is equal to the amount required to
    purchase one or more whole Shares on the final Purchase Date of the Offering
    shall be distributed in full to the Participant at the end of the Offering,
    without interest.

(c) The amount, if any, of accumulated payroll deductions remaining in any
    Participant's account after the purchase of Shares that is less than the
    amount required to purchase one whole Share on the final Purchase Date of
    the Offering shall be carried forward, without interest, into the next
    Offering.

(d) No Rights granted under the Plan may be exercised to any extent unless the
    Shares to be issued upon such exercise under the Plan (including Rights
    granted thereunder) are covered by an effective registration statement
    pursuant to the Securities Act and the Plan is in material compliance with
    all applicable state, foreign and other securities and other laws applicable
    to the Plan. If on a Purchase Date in any Offering hereunder the Plan is not
    so registered or in such compliance, no Rights granted under the Plan or any
    Offering shall be exercised on such Purchase Date, and the Purchase Date
    shall be delayed until the Plan is subject to such an effective registration
    statement and such compliance, except that the Purchase Date shall not be
    delayed more than twelve (12) months and the Purchase Date shall in no event
    be more than twenty-seven (27) months from the Offering Date. If, on the
    Purchase Date of any Offering hereunder, as delayed to the maximum extent
    permissible, the Plan is not registered and in such compliance, no Rights
    granted under the Plan or any Offering shall be exercised and all payroll
    deductions accumulated during the Offering (reduced to the extent, if any,
    such deductions have been used to acquire Shares) shall be distributed to
    the Participants, without interest.

10. RESTRICTIONS ON SHARES.

    The Board or the Committee may in its discretion impose such transfer or
other restrictions upon Shares purchased under the Plan as it shall determine in
its sole discretion to be advisable.

11. COVENANTS OF THE COMPANY.

    The Company shall use its reasonable efforts to seek to obtain from each
federal, state, foreign or other regulatory commission or agency having
jurisdiction over the Plan such authority as may be required to issue and sell
Shares upon exercise of the Rights granted under the Plan. If, after reasonable
efforts, the Company is unable to obtain from any such regulatory commission or
agency the authority which counsel for the Company deems necessary for the
lawful issuance and sale of Shares under the Plan, the Company shall be relieved
from any liability for failure to issue and sell Shares upon exercise of such
Rights unless and until such authority is obtained.

12. USE OF PROCEEDS FROM SHARES.
<PAGE>

    Proceeds from the sale of Shares pursuant to Rights granted under the Plan
shall constitute general funds of the Company.

13. RIGHTS AS A STOCKHOLDER AND EMPLOYEE.

(a) A Participant shall not be deemed to be the holder of, or to have any of the
    rights of a holder with respect to, Shares subject to Rights granted under
    the Plan unless and until the Participant's Shares acquired upon exercise of
    Rights under the Plan are recorded in the books of the Company.

(b) Neither the Plan nor the grant of any Right thereunder shall confer any
    right on any Employee to remain in the employ of the Company or any
    Affiliate or restrict the right of the Company or any Affiliate to terminate
    such Employee's employment.

(c) The Committee may impose such additional restrictions on Shares purchased in
    an Offering as it shall determine in its sole discretion, provided that any
    such restriction is disclosed in the Offering Memorandum for such Offering.

14. ADJUSTMENTS UPON CHANGES IN SECURITIES.

(a) Subject to any required action by the stockholders of the Company, the
    number of Shares covered by each Right under the Plan that has not yet been
    exercised and the number of Shares that have been authorized for issuance
    under the Plan but have not yet been placed under a Right (collectively, the
    "Reserves"), as well as the price per Share covered by each Right under the
    Plan that has not yet been exercised, shall be proportionately adjusted for
    any increase or decrease in the number of issued Shares resulting from a
    stock split or the payment of stock dividend (but only on the Common Stock)
    or any other increase or decrease in the number of Shares effected without
    receipt of consideration by the Company; provided, however, that conversion
    of any convertible securities of the Company shall not be deemed to have
    been "effected without receipt of consideration." Such adjustment shall be
    made by the Committee, whose determination in that respect shall be final,
    binding and conclusive. Except as expressly provided herein, no issue by the
    Company of shares of stock of any class, or securities convertible into
    shares of stock of any class, shall affect, and no adjustment by reason
    thereof shall be made with respect to, the number or price of Shares subject
    to a Right.

(b) In the event of the proposed dissolution or liquidation of the Company, any
    and all Offerings shall terminate immediately prior to the consummation of
    such proposed action, unless otherwise provided by the Committee. The
    Committee may, in the exercise of its sole discretion in such instances,
    declare that the Rights under the Plan shall terminate as of a date fixed by
    the Committee and give each Participant the right to exercise his or her
    Right. In the event of a proposed sale of all or substantially all of the
    assets of the Company, or the merger or consolidation of the Company with or
    into another corporation or a parent or subsidiary of such successor
    corporation when the Company is not the surviving corporation, or a reverse
    merger in which the Company is the surviving corporation but the Shares
    outstanding immediately preceding the merger are converted by virtue of the
    merger into other property, whether in the form of securities, cash or
    otherwise, any and all Offerings shall terminate immediately prior to the
    consummation of such proposed action, unless otherwise provided by the
    Committee. The Committee may, in the exercise of its sole discretion in such
    instances, and in lieu of assumption or substitution of the Rights, provide
    that each Participant shall have the right to exercise his or her Right. If
    the Committee makes a Right exercisable in lieu of assumption or
    substitution in the event of a merger or sale of assets, the Committee shall
    notify the Participant that the Right shall be fully exercisable for a
    period of twenty (20) days from the date of such notice (or such other
    period of time as the Committee shall determine), and the Right shall
    terminate upon the expiration of such period.

(c) The Committee may, if it so determines in the exercise of its sole
    discretion, also make provision for adjusting the Reserves, as well as the
    price per Share covered by each outstanding Right, in the event that the
    Company
<PAGE>

    effects one or more reorganizations, recapitalizations, rights offering, or
    other increases or reductions of outstanding Shares, and in the event of the
    Company being consolidated with or merged into any other corporation.

15. AMENDMENT OF THE PLAN.

(a) The Board or the Committee at any time, and from time to time, may amend the
    Plan. However, any amendment shall be subject to approval by the
    stockholders of the Company if stockholder approval is necessary for the
    Plan to satisfy the requirements of Section 423 of the Code or any stock
    market or securities exchange listing requirements. As of the date of this
    Plan, under the Code, stockholder approval within twelve (12) months before
    or after the adoption of the amendment is required where the amendment will:

    (i)   Increase the amount of Shares reserved for Rights under the Plan; or

    (ii)  Modify the provisions as to eligibility for participation in the Plan
          to the extent such modification requires stockholder approval in order
          for the Plan to obtain employee stock purchase plan treatment under
          Section 423 of the Code.

(b) It is expressly contemplated that the Committee or the Board may amend the
    Plan in any respect the Committee or the Board deems necessary or advisable
    to provide Employees with the maximum benefits provided or to be provided
    under the provisions of the Code and the regulations promulgated thereunder
    relating to Employee Stock Purchase Plans and/or to bring the Plan and/or
    Rights granted under it into compliance therewith.

(c) Rights and obligations under any Rights granted before amendment of the Plan
    may be subject to or affected by any amendment of the Plan without the
    consent of the person to whom such Rights were granted, except as necessary
    to ensure that the Plan and/or Rights granted under the Plan comply with the
    requirements of Section 423 of the Code.

16. DESIGNATION OF BENEFICIARY.

(a) A Participant may file a written designation of a beneficiary who is to
    receive any Shares and/or cash, if any, from the Participant's account under
    the Plan in the event of such Participant's death subsequent to the end of
    an Offering but prior to delivery to the Participant of such Shares and
    cash. In addition, a Participant may file a written designation of a
    beneficiary who is to receive any cash from the Participant's account under
    the Plan in the event of such Participant's death during an Offering.

(b) The Participant may change such designation of beneficiary at any time by
    written notice. In the event of the death of a Participant and in the
    absence of a beneficiary validly designated under the Plan who is living at
    the time of such Participant's death, the Company shall deliver such Shares

================================================================================

FOR VALUE RECEIVED, the undersigned Borrower unconditionally (and jointly and
severally, if more than one) promises to pay to the order of Bank, its
successors and assigns, without setoff, at its offices indicated at the
beginning of this Note, or at such other place as may be designated by Bank, the
principal amount of Ten Million and 00/100 Dollars ($ 10,000,000.00 ), or so
                    ----------------------         ------------------
much thereof as may be advanced from time to time in immediately available
funds, together with interest computed daily on the outstanding principal
balance hereunder, at an annual interest rate, and in accordance with the
payment schedule, indicated below.

[This Note contains some provisions preceded by boxes. If a box is marked, the
provision applies to this transaction; if it is not marked, the provision does
not apply to this transaction.]

1. Rate.

The Rate shall be the Eurodollar Daily Floating Rate plus .75 percent, per
                                                     --------
annum. The "Eurodollar Daily Floating Rate" is a fluctuating rate of interest
equal to the one month rate of interest (rounded upwards, if necessary to the
             ---------
nearest 1/100 of 1 %) appearing on Telerate Page 3750 (or any successor page) as
the one month London interbank offered rate for deposits in Dollars at
    ---------
approximately 11:00 a.m. (London time) on the second preceding business day, as
adjusted from time to time in Bank's sole discretion for then-applicable reserve
requirements, deposits insurance assessment rates and other regulatory costs. If
for any reason such rate is not available, the term "Eurodollar Daily Floating
Rate" shall mean the fluctuating rate of interest equal to the one month rate of
                                                               ---------
of interest (rounded upwards, if necessary to the nearest 1/100 of 1 %)
appearing on Reuters Screen LIBO Page as the one month London interbank offered
                                             ---------
rate for deposits in Dollars at approximately 11:00 a.m. (London time) on the
second preceding business day, as adjusted from time to time in Bank's sole
discretion for then-applicable reserve requirements, deposits insurance
assessment rates and other regulatory costs; provided, however, if more than one
rate is specified on Reuters Screen LIBO page, the applicable rate shall be the
arithmetic mean of all such rates.

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by the applicable law of the District of
Columbia; if any higher rate ceiling is lawful, then that higher rate ceiling
shall apply. Any payment in excess of such maximum shall be refunded to Borrower
or credited against principal, at the option of Bank.

2. Accrual Method. Unless otherwise indicated, interest at the Rate set forth
above will be calculated by the 365/360 day method (a daily amount of interest
is computed for a hypothetical year of 360 days; that amount is multiplied by
the actual number of days for which any principal is outstanding hereunder). If
interest is not to be computed using this method, the method shall be: N/A.
                                                                       ---

3. Rate Change Date. Any Rate based on a fluctuating index or base rate will
change, unless otherwise provided, each time and as of the date that the index
or base rate changes. If the Rate is to change on any other date or at any other
interval, the change shall be: N/A . In the event any index is discontinued,
                               ----
Bank shall substitute an index determined by Bank to be comparable, in its sole
discretion.

4. Payment Schedule. All payments received hereunder shall be applied first to
the payment of any expense or charges payable hereunder or under any other loan
documents executed in connection with this Note, then to interest due and
payable, with the balance applied to principal, or in such other order as Bank
shall determine at its option.

Single Principal Payment. Principal shall be paid in full in a single payment on
May 25, 2002. Interest thereon shall be paid monthly, commencing on June 30,
------------                                 -------                --------
2000, and continuing on the last day of each successive month, quarter or other
----                        ----
period (as applicable) thereafter, with a final payment of all unpaid interest
at the stated maturity of this Note.

5. Revolving Feature.

[X] Borrower may borrow, repay and reborrow hereunder at any time, up to a
maximum aggregate amount outstanding at any one time equal to the principal
amount of this Note, provided, that Borrower is not in default under any
provision of this Note, any other documents executed in connection with this
Note, or any other note or other loan documents now or hereafter executed in
connection with any other obligation of Borrower to Bank, and provided that the
borrowings hereunder do not exceed any borrowing base or other limitation on
borrowings by Borrower. Bank shall incur no liability for its refusal to advance
funds based upon its determination that any conditions of such further advances
have not been met. Bank records of the amounts borrowed from time to time shall
be conclusive proof thereof.

                                      -1-
<PAGE>

   [_] Uncommitted Facility. Borrower acknowledges and agrees that,
   notwithstanding any provisions of this Note or any other documents executed
   in connection with this Note, Bank has no obligation to make any advance, and
   that all advances are at the sole discretion of Bank.

   [_] Out-Of-Debt Period. For a period of at least ___ consecutive days during
   [_] each fiscal year, [_] any consecutive 12-month period, Borrower shall
   fully pay down the balance of this Note, so that no amount of principal or
   interest and no other obligation under this Note remains outstanding.

6. Automatic Payment.

[X] Borrower has elected to authorize Bank to effect payment of sums due under
this Note by means of debiting Borrower's account number 001920586593. This
                                                         ------------
authorization shall not affect the obligation of Borrower to pay such sums when
due, without notice, if there are insufficient funds in such account to make
such payment in full on the due date thereof, or if Bank fails to debit the
account.

7. Waivers, Consents and Covenants. Borrower, any indorser, or guarantor hereof
or any other party hereto (individually an "Obligor" and collectively
"Obligors") and each of them jointly and severally: (a) waive presentment,
demand, protest, notice of demand, notice of intent to accelerate, notice of
acceleration of maturity, notice of protest, notice of nonpayment, notice of
dishonor, and any other notice required to be given under the law to any Obligor
in connection with the delivery, acceptance, performance, default or enforcement
of this Note, any indorsement or guaranty of this Note, or any other documents
executed in connection with this Note or any other note or other loan documents
now or hereafter executed in connection with any obligation of Borrower to Bank
(the "Loan Documents"); (b) consent to all delays, extensions, renewals or other
modifications of this Note or the Loan Documents, or waivers of any term hereof
or of the Loan Documents, or release or discharge by Bank of any of Obligors, or
release, substitution or exchange of any security for the payment hereof, or the
failure to act on the part of Bank, or any indulgence shown by Bank (without
notice to or further assent from any of Obligors), and agree that no such
action, failure to act or failure to exercise any right or remedy by Bank shall
in any way affect or impair the obligations of any Obligors or be construed as a
waiver by Bank of, or otherwise affect, any of Bank's rights under this Note,
under any indorsement or guaranty of this Note or under any of the Loan
Documents; and (c) agree to pay, on demand, all costs and expenses of collection
or defense of this Note or of any indorsement or guaranty hereof and/or the
enforcement or defense of Bank's rights with respect to, or the administration,
supervision, preservation, protection of, or realization upon, any property
securing payment hereof, including, without limitation, reasonable attorney's
fees, including fees related to any suit, mediation or arbitration proceeding,
out of court payment agreement, trial, appeal, bankruptcy proceedings or other
proceeding, in the amount of 10% of the principal amount of this Note, or such
greater amount as may be determined reasonable by any arbitrator or court,
whichever is applicable.

8. Prepayments. Prepayments may be made in whole or in part at any time on any
loan for which the Rate is based on the Prime Rate or on any other fluctuating
Rate or index which may change daily. All prepayments of principal shall be
applied in the inverse order of maturity, or in such other order as Bank shall
determine in its sole discretion. No prepayment of any other loan shall be
permitted without the prior written consent of Bank. Notwithstanding such
prohibition, if there is a prepayment of any such loan, whether by consent of
Bank, or because of acceleration or otherwise, Borrower shall, within 15 days of
any request by Bank, pay to Bank any loss or expense which Bank may incur or
sustain as a result of such prepayment. For the purposes of calculating the
amounts owed only, it shall be assumed that Bank actually funded or committed to
fund the loan through the purchase of an underlying deposit in an amount and for
a term comparable to the loan, and such determination by Bank shall be
conclusive, absent a manifest error in computation.

9. Delinquency Charge. To the extent permitted by law, a delinquency charge may
be imposed in an amount not to exceed four percent (4%) of any payment that Is
more than fifteen days late.

10. Events of Default. The following are events of default hereunder: (a) the
failure to pay or perform any obligation, liability or indebtedness of any
Obligor to Bank, or to any affiliate or subsidiary of Bank of America
Corporation, whether under this Note or any Loan Documents, as and when due
(whether upon demand, at maturity or by acceleration); (b) the failure to pay or
perform any other obligation, liability or indebtedness of any Obligor to any
other party; (c) the death of any Obligor (if an individual); (d) the
resignation or withdrawal of any partner or a material owner/Guarantor of
Borrower, as determined by Bank in its sole discretion; (e) the commencement of
a proceeding against any Obligor for dissolution or liquidation, the voluntary
or involuntary termination or dissolution of any Obligor or the merger or
consolidation of any Obligor with or into another entity; (f) the insolvency of,
the business failure of, the appointment of a custodian, trustee, liquidator or
receiver for or for any of the property of, the assignment for the benefit of
creditors by, or the filing of a petition under bankruptcy, insolvency or
debtor's relief law or the filing of a petition for any adjustment of
indebtedness, composition or extension by or against any Obligor; (g) the
determination by Bank that any representation or warranty made to Bank by any
Obligor in any Loan Documents or otherwise is or was, when it was made, untrue
or materially misleading; (h) the failure of any Obligor to timely deliver such
financial statements, including tax returns, other statements of condition or
other information, as Bank shall request from time to time; (i) the entry of a
judgment against any Obligor which Bank deems to be of a material nature, in
Bank's sole discretion; (j) the seizure or forfeiture of, or the issuance of
any writ of possession, garnishment or attachment, or any turnover order for any
property of any Obligor; (k) the determination by Bank that a material adverse
change has occured in the financial condition of any Obligor; or (l) the
material failure of Borrower's business to comply with any law or regulation
controlling its operation.

11. Remedies upon Default. Whenever there is a default under this Note (a) the
entire balance outstanding hereunder and all other obligations of any Obligor
to Bank (however acquired or evidenced) shall, at the option of Bank, become
immediately due and payable and any obligation of Bank to permit further
borrowing under this Note shall immediately cease and terminate, and/or (b) to
the extent permitted by law, the Rate of interest on the unpaid principal shall
be increased at Bank's discretion up to the maximum rate allowed by law, or if
none, 25% per annum (the "Default Rate"). The provisions herein for a Default
Rate shall not be deemed to extend the time for any payment hereunder or to
constitute a "grace period" giving Obligors a right to cure any default. At
Bank's option, any accrued and unpaid interest, fees or charges may, for
purposes of computing and accruing interest on a daily basis after the due date
of the Note or any installment thereof, be deemed to be a part of the principal
balance, and interest shall accrue on a daily compounded basis after such date
at the Default Rate provided in this Note until the entire outstanding balance
of principal and interest is paid in full. Bank is hereby authorized at any time
to set off and charge against any deposit accounts of any Obligor, as well as
any money, instruments, securities, documents, chattel paper, credits, claims,
demands, income and any other property, rights and interests of any Obligor
which at any time shall come into the possession or custody or under the control
of Bank or any of its agents, affiliates or correspondents, without notice or
demand, any and all obligations due hereunder. Additionally, Bank shall have all
rights and remedies available under each of the Loan Documents, as well as all
rights and remedies available at law or in equity.

                                      -2-
<PAGE>

12. Non-Waiver. The failure at any time. Bank to exercise any of its options or
any other rights hereunder shall not constitute a waiver thereof, nor shall it
be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of Bank's
rights under this Note. No waiver of any of its rights hereunder, and no
modification or amendment of this Note, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; each such
waiver shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Bank or the obligations of Obligor to Bank
in any other respect at any other time.

13. Applicable Law, Venue and Jurisdiction. This Note and the rights and
obligations of Borrower and Bank shall be governed by and interpreted in
accordance with the law of the District of Columbia. In any litigation in
connection with or to enforce this Note or any indorsement or guaranty of this
Note or any Loan Documents, Obligors, and each of them, irrevocably consent to
and confer personal jurisdiction on the courts of the District of Columbia or
the United States located within the District of Columbia and expressly waive
any objections as to venue in any such courts. Nothing contained herein shall,
however, prevent Bank from bringing any action or exercising any rights within
any other state or jurisdiction or from obtaining personal jurisdiction by any
other means available under applicable law.

14. Partial Invalidity. The unenforceability or invalidity of any provision of
this Note shall not affect the enforceability or validity of any other provision
herein and the invalidity or unenforceability of any provision of this Note or
of the Loan Documents to any person or circumstance shall not affect the
enforceability or validity of such provision as it may apply to other persons or
circumstances.

15. Binding Effect. This Note shall be binding upon and inure to the benefit of
Borrower, Obligors and Bank and their respective successors, assigns, heirs and
personal representatives, provided, however, that no obligations of Borrower or
Obligors hereunder can be assigned without prior written consent of Bank.

16. Controlling Document. To the extent that this Note conflicts with or is in
any way incompatible with any other Loan Document concerning this obligation,
the Note shall control over any other document, and if the Note does not address
an issue, then each other document shall control to the extent that it deals
most specifically with an issue.

subsidiaries and affiliates that could be adversely affected by failure to

any computer application which is material to the operations of Borrower, its
subsidiaries or any of its material vendors or suppliers will not be fully Year

not reasonably be expected to have a material adverse effect upon the financial
condition of Borrower.
