                                PROMISSORY NOTE

                                                                February 8, 2000

U.S. $4,000,000.00

FOR VALUE RECEIVED, the undersigned, QMS Europe B.V., a corporation organized
under the laws of The Netherlands ("Maker"), promises to pay to the order of
QMS, Inc., a corporation organized under the laws of the State of Delaware
(herein, along with each subsequent holder of this Note, referred to as
"Holder"), the principal sum of FOUR MILLION AND 00/100 DOLLARS (US
$4,000,000.00) plus interest as provided herein.

The applicable interest rate for this Note (the "Applicable Rate") shall be an
adjustable rate per annum equal to three percent (3.00%) in excess of "LIBOR"
(as defined herein) from time to time in effect, but in no event less than a
rate of six and one-half percent (6.50%) per annum.  "LIBOR" refers to (i) the
London Interbank Offered Rate for the applicable LIBOR Adjustment Period as
quoted on the Telerate Information System on the date of determination of the
Applicable Rate (or in the event no such quotation is available on such data, as
quoted on the day most immediately preceding the date of determination on which
such a quotation was available), or (ii) in the event the Telerate Information
System ceases to be available or ceases to provide information sufficient to
determine the London Interbank Offered Rate for the applicable LIBOR Adjustment
Period (as defined herein), the London Interbank Offered Rate for the applicable
LIBOR Adjustment Period as published in the Wall Street Journal on the date of
determination of the interest rate (or in the event no such quotation is
available on such date, as quoted on the day most immediately preceding the date
of determination on which such a quotation was available).  The Applicable Rate
shall be determined as of the date hereof and as of the first day following the
end of each succeeding ninety (90) day period ("LIBOR Adjustment Period") during
the remaining term of this Note (or in the event no such quotation is available
on such date, as quoted on the day most immediately preceding the date of
determination on which such a quotation was available) (the "Interest Adjustment
Dates") and will be adjusted as of each Interest Adjustment Date to correspond
to any change in the ninety (90) day LIBOR rate.

Throughout the term of this Note, interest payments shall be made in monthly
installments, commencing on March 10, 2000.  Interest payments shall be computed
on the basis of the prevailing Applicable Rate and the actual principal sum
outstanding from time to time.  Principal due hereunder shall be repaid in
forty-seven (47) consecutive monthly installments in the amount of $83,333.33
each commencing on March 10, 2000, and a final forty-eighth (48th) payment of
all principal, interest and other amounts due under this Note, which forty-
eighth (48th) payment shall be due and payable on February 8, 2004, the maturity
date of this Promissory Note.

Should the principal or any interest hereunder not be paid when due, the Holder
shall have the right to declare the unpaid principal and all accrued interest of
this Note to be forthwith due and payable, in which event the remaining
principal balance due and unpaid hereunder shall bear interest at a per annum
rate equal to the Applicable Rate in force from time to time, plus two percent
(2%).

The principal hereof and any interest hereon shall be payable in lawful money of
the United States of America, at such place as the Holder may designate in
writing to Maker. The Maker may prepay this Note in full or in part at any time
without notice, penalty or prepayment fee.

Maker agrees to pay the Holder hereof reasonable attorneys' fees for the
services of counsel employed to collect this Note, whether or not suit be
brought, and whether incurred in connection with collection, trial, appeal, or
otherwise.

In no event shall the amount of interest due and payable hereunder exceed the
maximum rate of interest allowed by applicable law, and in the event any such
payment is inadvertently paid by Maker or
<PAGE>

inadvertently received by Holder, then such excess shall be credited as a
payment of principal, unless Maker shall notify the Holder, in writing, that
Maker elected to have such excess sum returned to it forthwith. It is the
express intent hereof that Maker not pay and Holder not receive, directly or
indirectly, in any manner whatsoever, interest in excess of that which may be
lawfully paid by the Maker under applicable law.

The remedies of Holder as provided herein and in any other documents governing
repayment hereof shall be cumulative and concurrent and may be pursued singly,
successively, or together, at the sole discretion of Holder, and may be
exercised as often as occasion therefor shall arise.

No act of omission or commission of Holder, including specifically any failure
to exercise any right, remedy, or recourse, shall be effective unless set forth
in a written document executed by Holder, and then only to the extent
specifically recited therein.  A waiver or release with reference to one event
shall not be construed as continuing, as a bar to, or as a waiver or release of
any subsequent right, remedy, or recourse as to any subsequent event.

Maker hereby (a) waives demand, presentment of payment, notice of nonpayment,
protest, notice of protest and all other notice, filing of suit, and diligence
in collecting this Note and (b) agrees that the Holder shall not be required to
institute any suit, or to exhaust its remedies against Maker in order to enforce
payments of this Note.

Whenever used in this Note, the words "Maker" and "Holder" shall be deemed to
include Maker and the Holder named in the opening paragraph of this Note, and
their respective legal representatives, successors, and assigns.  It is
expressly understood and agreed that the Holder shall never be construed for any
purpose as a partner, joint venturer, co-principal, or associate of Maker, or of
any person or party claiming by, through, or under Maker in the conduct of their
respective businesses.

Time is of the essence of this Note.

This Note shall be construed and enforced in accordance with the laws of the
State of Alabama.

IN WITNESS WHEREOF, the undersigned Maker has executed this instrument under
seal as of the day and year first above written.

                            STOCK WARRANT AGREEMENT

April 15, 1999                                                    17,500 Shares

     Warrants to purchase 17,500 shares of Common Stock (the "Shares") of Unity

conditions:

     51.  Exercise of Warrants.  The warrants granted in this agreement (the
          --------------------
"Warrants") may be exercised in whole or in part at any time after November 30,
1999 (the "Vesting Date").  Exercise of the Warrants is subject to the
following:

          (a) Exercise Price.  The exercise price (the "Exercise Price") shall
              --------------
              be $10.00 per Share, subject to adjustment pursuant to Section 2
              below.

          (b) Expiration of Warrant Term.  The Warrants will expire at 5:00 p.m.
              --------------------------
              Eastern Standard Time on November 30, 2008, and may not be
              exercised thereafter (the "Expiration Date").

          (c) Payment.  The purchase price for Shares as to which the Warrants
              -------
              are being exercised shall be paid in cash, by wire transfer, by
              certified or bank cashier's check, or by personal check drawn on
              funds on deposit with Unity National Bank (the "Bank").

          (d) Method of Exercise.  The Warrants shall be exercisable by a
              ------------------
              written notice delivered to the President or Secretary of the
              Company which shall:

              (i)   State the owner's election to exercise the Warrants, the
                    number of Shares with respect to which it is being
                    exercised, the person in whose name the stock certificate
                    for such Shares is to be registered and such person's
                    address and tax identification number (or, if more than
                    one, the names, addresses and tax identification numbers of
                    such persons);

              (ii)  Be signed by the person or persons entitled to exercise the
                    Warrants and, if the Warrants are being exercised by any
                    person or persons other than the original holder thereof,
                    be accompanied by proof satisfactory to counsel for the
                    Company of the right of such person or persons to exercise
                    the Warrants; and

                                       1
<PAGE>

              (iii) Be accompanied by the originally executed copy of this
                    Stock Warrant Agreement.

          (e) Partial Exercise.  In the event of a partial exercise of the
              ----------------
              Warrants, the Company shall either issue a new agreement for the
              balance of the Shares subject to this Stock Warrant Agreement
              after such partial exercise, or it shall conspicuously note hereon
              the date and number of Shares purchased pursuant to such exercise
              and the number of Shares remaining covered by this Stock Warrant
              Agreement.

          (f) Restrictions on Exercise.  The Warrants may not be exercised (i)
              ------------------------
              if the issuance of the Shares upon such exercise would constitute
              a violation of any applicable federal or state securities laws or
              other law or regulation or (ii) unless the Company or the holder
              hereof, as applicable, obtains any approval or other clearance
              which the Company determines to be necessary or advisable from the
              Federal Reserve Board, the Office of the Comptroller of the
              Currency, the Federal Deposit Insurance Corporation or any other
              state or federal banking regulatory agency with regulatory
              authority over the operation of the Company or the Bank
              (collectively the "Regulatory Agencies"). The Company may require
              representations and warranties from the Warranty Holder as
              required to comply with applicable laws or regulations, including
              the Securities Act of 1933 and state securities laws.

     52.  Anti-Dilution; Merger.  If, prior to the exercise of Warrants
          ---------------------
hereunder, the Company (i) declares, makes or issues, or fixes a record date for
the determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable on the Shares in shares of its capital stock, (ii)
subdivides the outstanding Shares, (iii) combines the outstanding Shares, (iv)
issues any shares of its capital stock by reclassification of the Shares,
capital reorganization or otherwise (including any such reclassification or
reorganization in connection with a consolidation or merger or and sale of all
or substantially all of the Company's assets to any person), then the Exercise
Price, and the number and kind of shares receivable upon exercise, in effect at
the time of the record date for such dividend or of the effective date of such
subdivision, combination or reclassification shall be proportionately adjusted
so that the holder of any Warrant exercised after such time shall be entitled to
receive the aggregate number and kind of shares which, if such Warrant had been
exercised immediately prior to such time, he would have owned upon such exercise
and been entitled to receive by virtue of such dividend, distribution,
subdivision, combination, reclassification, reorganization, consideration,
merger or sale.

     53.  Valid Issuance of Common Stock.  The Company possesses the full
          ------------------------------
authority and legal right to issue, sell, transfer, and assign this Warrant and
the Shares issuable pursuant to this Warrant.  The issuance of this Warrant
vests in the holder the entire legal and

                                       2
<PAGE>

beneficial interests in this Warrant, free and clear of any liens, claims, and
encumbrances and subject to no legal or equitable restrictions of any kind
except as described herein. The Shares that are issuable upon exercise of this
Warrant, when issued, sold and delivered in accordance with the terms of this
Agreement for the consideration expressed herein, will be duly and validly
issued, fully paid, and non-assessable, and will be free of restrictions on
transfer other than restrictions under applicable state and federal securities.

     54.  Compliance with Securities Laws.  Warrant Holder understands that the
          -------------------------------
Warrants and the Shares issuable upon exercise of the Warrants may not be sold,
transferred or otherwise disposed of without registration under the Securities
Act of 1933, or an exemption therefrom, and that in the absence of an effective
registration statement covering such shares or an available exemption from
registration under the Securities Act, such Shares must be held indefinitely.

     55.  Restrictions on Transferability.  This Agreement, the Warrants, and
          -------------------------------
the Shares issuable on exercise of the Warrants may not assigned or transferred
by the Warrant Holder without the Company's prior written consent and, if so
requested by the Company, the delivery by the Warrant Holder to the Company of
an opinion of counsel in form and substance satisfactory to the Company stating
that such transfer or assignment is in compliance with the Securities Act of
1933 and applicable state securities laws.  More particularly, but without
limiting the generality of the foregoing, the Warrants may not be assigned,
transferred (except as provided above), pledged or hypothecated in any way
(whether by operation of law or otherwise) and shall not be subject to
execution, attachment or similar process.  Any attempted assignment, transfer,
pledge, hypothecation or other disposition of these Warrants contrary to the
provisions hereof shall be without legal effect.

     56.  Restrictive Legend.  Each certificate for Shares issued upon exercise
          ------------------
of the Warrant shall bear a legend stating that they have not been registered
under the Securities Act of 1933 or any state securities laws and referring to
the restrictions on transferability and sale herein.

     57.  Mandatory Exercise; Termination.
          --------- ---------------------

          (a) The Company or the Bank may be required to increase its capital to
              meet capital requirements imposed by statute, rule, regulation, or
              guideline. In order to achieve such capital increase, the
              Regulatory Agencies may direct the Company to require the Warrant
              Holders to either (i) exercise all or part of their Warrants or
              (ii) allow the Warrants to be terminated. If the Regulatory
              Agencies so direct the Company, then the Warrant Holder must
              exercise or forfeit the Warrants as set forth below.

          (b) When the Company or the Bank is required to increase its capital
              as described in subsection (a) above, the Company shall send a
              notice (the

                                       3
<PAGE>

              "Notice") to the Warrant Holder (i) specifying the number of
              Shares relating to the Warrants for which the Warrants must be
              exercised (the "Number") (if less than all shares relating to
              warrants held by all holders of warrants of the Company under
              agreements substantially similar to this one are required by the
              Company to be exercised or canceled, the Number for the Warrant
              Holder shall reflect a proportionate allocation based on the
              number of Shares subject to this Agreement as compared to the
              total number of shares subject to warrants held by all such
              warrant holders as a group); (ii) specifying the date prior to
              which the Warrants must be totally or partially exercised, as the
              case may be (the "Deadline"); (iii) specifying the Exercise Price
              for the Shares to be purchased pursuant to the Warrants (such
              Exercise Price not to be less than current book value per share);
              and (iv) stating that the failure of the Warrant holder to
              exercise the Warrants shall result in their automatic termination.

          (c) If the Warrant holder does not exercise the Warrants pursuant to
              the terms of the Notice, this Agreement shall be automatically
              terminated on the Deadline, without further act or action by the
              Warrant Holder or the Company, and the Warrant Holder shall
              deliver this Agreement to the Company for cancellation. If the
              Number is less than the total number of Shares that are then
              subject to exercise under this Agreement, the Company shall issue
              a new Stock Warrant Agreement in compliance with Section 1(e)
              hereof.

     58.  Covenants of the Company.  During the term of the Warrants, the
          ------------------------
Company shall:

          (a) at all times authorize, reserve and keep available, solely for
              issuance upon exercise of this Warrant, sufficient shares of
              common stock from time to time issuable upon exercise of this
              Warrant;

          (b) on receipt of evidence reasonably satisfactory to the Company of
              the loss, theft, destruction or mutilation of this Warrant and, in
              the case of loss, theft, or destruction, on delivery of any
              indemnity agreement or bond reasonably satisfactory in form and
              amount to the Company or, in the case of mutilation, on surrender
              and cancellation of this Warrant, at its expense execute and
              deliver, in lieu of this Warrant, a new Warrant of like tenor; and

          (c) on surrender for exchange of this Warrant or any Warrant
              substituted therefor pursuant hereto, properly endorsed, to the
              Company, at its expense, issue and deliver to or on the order of
              the holder thereof a new Warrant or Warrants of like tenor, in the
              name of such holder or as such

                                       4
<PAGE>

              holder (on payment by such holder of any applicable transfer
              taxes) may direct, calling in the aggregate on the face or faces
              thereof for the issuances of the number of shares of Common Stock
              issuable pursuant to the terms of the Warrant or Warrants so
              surrendered.

     59.  No Dilution or Impairment.  The Company shall not amend its
          -------------------------
Certificate of Incorporation or participate in any reorganization, transfer of
assets, consolidation, merger, dissolution, issuance or sale of securities or
any other voluntary action for the purpose of avoiding or seeking to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in carrying
out all such action as may be reasonably necessary in order to protect the
exercise rights of the holder against improper dilution or other impairment.

     60.  Amendment.  Neither this Agreement nor the rights granted hereunder
          ---------
may be amended, changed or waived except in writing signed by each party hereto.

     IN WITNESS WHEREOF, the Company has executed and the holder has accepted
this Stock Warrant Agreement as of the date and year first above written.
