                          THE NATIONAL REGISTRY INC.

                              WARRANT CERTIFICATE

                              Dated July 23, 1999


     THE NATIONAL REGISTRY INC., a Delaware corporation (the "Company"), hereby
certifies that, for value received, ____________, or its registered assigns
("Holder"), is entitled, subject to the terms set forth below, to purchase from
the Company up to a total of ________ shares of Common Stock, $.01 par value per
share (the "Common Stock"), of the Company (each such share, a "Warrant Share"
and all such shares, the "Warrant Shares") at an exercise price equal to $1.00
per share (as adjusted from time to time as provided in Section 7) ( the
"Exercise Price"), at any time and from time to time from and after the date
hereof and through and including ______, 2001 (the "Expiration Date"), and
subject to the following terms and conditions:

          1. REGISTRATION OF WARRANT. The Company shall register this Warrant,
upon records to be maintained by the Company for that purpose (the "Warrant
Register"), in the name of the record Holder hereof from time to time. The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, and the Company shall not be affected by
notice to the contrary.

          2. REGISTRATION OF TRANSFERS AND EXCHANGES. (a) The Company shall
register the transfer of any portion of this Warrant in the Warrant Register,
upon surrender of this Warrant, with the Form of Assignment attached hereto duly
completed and signed, to the Company at the office specified in or pursuant to
Section 3(b). Upon any such registration or transfer, a new warrant to purchase
Common Stock, in substantially the form of this Warrant (any such new warrant, a
"New Warrant"), evidencing the


                                       1
<PAGE>

portion of this Warrant so transferred shall be issued to the transferee and a
New Warrant evidencing the remaining portion of this Warrant not so transferred,
if any, shall be issued to the transferring Holder. The acceptance of the New
Warrant by the transferee thereof shall be deemed the acceptance of such
transferee of all of the rights and obligations of a holder of a Warrant.

          (b) This Warrant is exchangeable, upon the surrender hereof by the
Holder to the office of the Company specified in or pursuant to Section 3(b) for
one or more New Warrants, evidencing in the aggregate the right to purchase the
number of Warrant Shares which may then be purchased hereunder. Any such New
Warrant will be dated the date of such exchange.

       3. DURATION AND EXERCISE OF WARRANTS.

          (a) This Warrant shall be exercisable by the registered Holder on any
business day before 5:30 P.M., New York time, at any time and from time to time
on or after the date hereof to and including the Expiration Date. At 5:30 P.M.,
New York time on the Expiration Date, the portion of this Warrant not exercised
prior thereto shall be and become void and of no value.

          (b) Subject to Sections 2(b), 4 and 8, upon surrender of this Warrant,
with the Form of Election to Purchase attached hereto duly completed and signed,
to the Company at its office at 2502 Rocky Point Drive, Suite 100, Tampa,
Florida 33607, Attention: Chief Financial Officer, or at such other address as
the Company may specify in writing to the then registered Holder, and upon
payment of the Exercise Price multiplied by the number of Warrant Shares that
the Holder intends to purchase hereunder, in lawful money of the United States
of America, in cash or by certified or official bank check or checks, all as
specified by the Holder in the Form of Election to Purchase, the Company shall
promptly (but in no event later than 3 business days after the date of exercise)
issue or cause to be issued and cause to be delivered to or upon the written
order of the Holder and in such name or names as the Holder may designate, a
certificate for the Warrant Shares issuable upon such exercise. Any person so
designated by the Holder to receive Warrant Shares shall be deemed to have
become holder of record of such Warrant Shares as of the Date of Exercise of
this Warrant.

          A "Date of Exercise" means the date on which the Company shall have
received (i) this Warrant (or any New Warrant, as applicable), with the Form of
Election to Purchase attached hereto (or attached to such New Warrant)
appropriately completed and duly signed, and (ii) payment of the Exercise Price
for the number of Warrant Shares so indicated by the holder hereof to be
purchased.

          (c) This Warrant shall be exercisable, either in its entirety or, from
time to time, for a portion of the number of Warrant Shares so long as at least
10,000 Warrant Shares are purchased in any one exercise. If less than all of the
Warrant Shares which may be purchased under this Warrant are exercised at any
time, the Company shall issue or cause to be issued, at its expense, a New
Warrant evidencing the right to purchase the remaining number of Warrant Shares
for which no exercise has been evidenced by this Warrant.

                                       2
<PAGE>

          (d) This Warrant shall only be exercisable if, and shall be only
exercisable to the extent, it is legal to do so because, among other things, the
Warrant Shares are registered pursuant to a registration statement which has
been declared effective by the Securities and Exchange Commission, and which is
still effective on the applicable date of exercise, or the issuance of such
Warrant Shares are exempt from the registration requirements of the Securities
Act of 1933, as amended.

       4. PAYMENT OF TAXES. The Company will pay all documentary stamp taxes
attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any certificates for Warrant Shares or Warrants in a name other than that of
the Holder, and the Company shall not be required to issue or cause to be issued
or deliver or cause to be delivered the certificates for Warrant Shares unless
or until the person or persons requesting the issuance thereof shall have paid
to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid. The Holder shall be
responsible for all other tax liability that may arise as a result of holding or
transferring this Warrant or receiving Warrant Shares upon exercise hereof.

       5. REPLACEMENT OF WARRANT. If this Warrant is mutilated, lost, stolen or
destroyed, the Company may in its discretion issue or cause to be issued in
exchange and substitution for and upon cancellation hereof, or in lieu of and
substitution for this Warrant, a New Warrant, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction and
indemnity, if requested, satisfactory to it. Applicants for a New Warrant under
such circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

       6. RESERVATION OF WARRANT SHARES. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but
unissued Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon the exercise of this entire
Warrant, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Holders (taking into account the adjustments
and restrictions of Section 7). The Company agrees to use its best efforts to
ensure that all Warrant Shares that shall be so issuable and deliverable shall,
upon issuance and the payment of the applicable Exercise Price in accordance
with the terms hereof, be duly and validly authorized, issued and fully paid and
nonassessable.

       7. CERTAIN ADJUSTMENTS. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this Section 7. Upon each such adjustment of the Exercise
Price pursuant to this Section 7, the Holder shall thereafter prior to the
Expiration Date be entitled to purchase, at the Exercise Price resulting from
such adjustment, the number of Warrant Shares obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

                                       3
<PAGE>

         (a) If the Company, at any time while this Warrant is outstanding, (i)
shall pay a stock dividend or otherwise make a distribution or distributions on
shares of its securities ranking junior as to dividend distributions and
distributions upon the liquidation, winding up and dissolution of the Company
("Junior Securities") payable in shares of Common Stock, (ii) subdivide
outstanding shares of Common Stock into a larger number of shares, or (iii)
combine outstanding shares of Common Stock into a smaller number of shares, the
Exercise Price shall be multiplied by a fraction of which the numerator shall be
the number of shares of Common Stock (excluding treasury shares, if any, but
including warrants or options that would be included for purposes of determining
earnings per share in accordance with generally accepted accounting principals)
outstanding before such event and of which the denominator shall be the number
of shares of Common Stock (excluding treasury shares, if any, but including
warrants or options that would be included for purposes of determining earnings
per share in accordance with generally accepted accounting principals)
outstanding after such event. Any adjustment made pursuant to this Section shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision or
combination, and shall apply to successive subdivisions and combinations.

         (b) In case of any reclassification of the Common Stock, any
consolidation or merger of the Company with or into another person, the sale or
transfer of all or substantially all of the assets of the Company or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification, consolidation, merger, sale,
transfer or share exchange, and the Holder shall be entitled upon such event to
receive such amount of securities or property equal to the amount of Warrant
Shares such Holder would have been entitled to had such Holder exercised this
Warrant immediately prior to such reclassification, consolidation, merger, sale,
transfer or share exchange. The terms of any such consolidation, merger, sale,
transfer or share exchange shall include such terms so as to give to the Holder
the right to receive the securities or property set forth in this Section 7(b)
as part of such reclassification, consolidation, merger, sale, transfer or share
exchange.

         (c) If the Company, at any time while this Warrant is outstanding,
shall distribute to all holders of Common Stock (and not to holders of this
Warrant) evidences of its indebtedness or assets (other than cash dividends) or
rights or warrants to subscribe for or purchase any security (excluding those
referred to in Sections 7(a), (b) and (d)), then in each such case the Exercise
Price shall be determined by multiplying the Exercise Price in effect
immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution by a fraction of which the denominator
shall be the Exercise Price determined as of the record date mentioned above,
and of which the numerator shall be such Exercise Price on such record date less
the then fair market value at such record date of the portion of such assets or
evidence of indebtedness so distributed applicable to one outstanding share of
Common Stock as determined by a nationally recognized or major regional
investment banking firm or firm of independent certified

                                       4
<PAGE>

public accountants of recognized standing (which may be the firm that regularly
examines the financial statements of the Company) (an "APPRAISER") selected in
good faith by the Company.

         (d)  If, at any time while this Warrant is outstanding, the Company
shall issue or cause to be issued rights or warrants to acquire or otherwise
sell or distribute shares of Common Stock to all holders of Common Stock for a
consideration per share less than the Exercise Price then in effect, then,
forthwith upon such issue or sale, the Exercise Price shall be reduced to the
price (calculated to the nearest cent) determined by dividing (i) an amount
equal to the sum of (A) the number of shares of Common Stock outstanding
immediately prior to such issue or sale multiplied by the Exercise Price, and
(B) the consideration, if any, received or receivable by the Company upon such
issue or sale by (ii) the total number of shares of Common Stock outstanding
immediately after such issue or sale.

         (e)  For the purposes of this Section 7, the following clauses shall
also be applicable:

                    (i)   RECORD DATE. In case the Company shall take a record
of the holders of its Common Stock for the purpose of entitling them (A) to
receive a dividend or other distribution payable in Common Stock or in
Convertible Securities, or (B) to subscribe for or purchase Common Stock or
Convertible Securities, then such record date shall be deemed to be the date of
the issue or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                    (ii)  TREASURY SHARES. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock.

         (f)  All calculations under this Section 7 shall be made to the nearest
cent or the nearest 1/100th of a share, as the case may be.

         (g)  Whenever the Exercise Price is adjusted pursuant to Section 7(c)
above or Section 7(i) below, the Company, after receipt of the determination by
the Appraiser shall have the right to select an additional Appraiser, in good
faith, in which case the adjustment shall be equal to the average of the
adjustments recommended by each Appraiser. The Company shall promptly mail or
cause to be mailed to each Holder, a notice setting forth the Exercise Price
after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Such adjustment shall become effective immediately after the
record date mentioned above. All determinations with respect to adjustments by
the Company hereunder shall be made by the Board of Directors in good faith.

         (h) If:


                                       5
<PAGE>

                    (i)    the Company shall declare a dividend (or
                           any other distribution) on its Common
                           Stock in Common Stock; or

                    (ii)   the Company shall declare a special
                           nonrecurring cash dividend on or a
                           redemption of its Common Stock; or

                    (iii)  the Company shall authorize the granting
                           to all holders of the Common Stock rights
                           or warrants to subscribe for or purchase
                           any shares of capital stock of any class
                           or of any rights; or

                    (iv)   the approval of any stockholders of the
                           Company shall be required in connection with
                           any reclassification of the Common Stock of
                           the Company, any consolidation or merger to
                           which the Company is a party, any sale or
                           transfer of all or substantially all of
                           the assets of the Company, or any compulsory
                           share exchange whereby the Common Stock is
                           converted into other securities, cash or
                           property; or

                    (v)    the Company shall authorize the voluntary
                           dissolution, liquidation or winding up of
                           the affairs of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, to the extent practicable at
least 20 calendar days prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, redemption, rights or
warrants, or if a record is not to be taken, the date as of which the holders of
Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, merger, sale, transfer or share exchange
is expected to become effective or close, and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, sale, transfer, share
exchange, dissolution, liquidation or winding up; PROVIDED, HOWEVER, that the
failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be specified
in such notice.

         (i) If at any time conditions shall arise by reason of action taken by
the Company which in the opinion of the Board of Directors are not adequately
covered by the other provisions hereof and which would reasonably be expected to
materially affect the rights of the Holders (different than or distinguished
from the effect generally on rights of holders of any class of the Company's
capital stock) or if any time such conditions are expected to arise by reason of
any action contemplated by the Company, the Company shall mail a written notice
briefly describing the action contemplated and the material adverse effects of
such action on the rights of the Holders to the extent practicable at least 20
calendar days prior to the effective date of such action, and an Appraiser
selected by the Holders of majority in interest of the Warrants then outstanding
and

                                       6
<PAGE>

consented to by the Company (which consent shall not be unreasonably withheld)
shall give its opinion as to the adjustment, if any (not inconsistent with the
standards established in this Section 7), of the Exercise Price (including, if
necessary, any adjustment as to the Warrant Shares to be purchased upon exercise
of this Warrant) and any distribution which is or would be required to be
preserved without diluting the rights of the Holders.

       8.  FRACTIONAL SHARES. The Company shall not be required to issue or
cause to be issued fractional Warrant Shares on the exercise of this Warrant.
The number of full Warrant Shares which shall be issuable upon the exercise of
this Warrant shall be computed on the basis of the aggregate number of Warrant
Shares purchasable on exercise of this Warrant so presented. If any fraction of
a Warrant Share would, except for the provisions of this Section 8, be issuable
on the exercise of this Warrant, the Company shall, at its option, (a) pay an
amount in cash equal to the Exercise Price multiplied by such fraction or (b)
shall round the number of Warrant Shares issuable, up to the next whole number
of such shares.

       9.  NOTICES. Any and all notices or other communications or deliveries
hereunder shall be in writing and shall be deemed given and effective on the
earliest of (i) the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section prior to 4:30 p.m. (Eastern Standard Time) on a business day, (ii) the
business day after the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section later than 4:30 p.m. (Eastern Standard Time) on any date and earlier
than 11:59 p.m. (Eastern Standard Time) on such date, (iii) the business day
following the date of mailing, if sent by nationally recognized overnight
courier service, or (iv) upon actual receipt by the party to whom such notice is
required to be given. The addresses for such communications shall be: (i) if to
the Company, to The National Registry Inc., 2502 Rocky Point Drive, Suite 100,
Tampa, Florida 33607, Attention: Chief Financial Officer, or to facsimile no.
(813) 636-0322, or (ii) if to the Holder, to the Holder at the address or
facsimile number appearing on the Warrant Register or such other address or
facsimile number as the Holder may provide to the Company in accordance with
this Section 9.

       10. WARRANT AGENT.

           (a) The Company shall serve as warrant agent under this Warrant. Upon
thirty (30) days' notice to the Holder, the Company may appoint a new warrant
agent.

           (b) Any corporation into which the Company or any new warrant agent
may be merged or any corporation resulting from any consolidation to which the
Company or any new warrant agent shall be a party or any corporation to which
the Company or any new warrant agent transfers substantially all of its
corporate trust or shareholders services business shall be a successor warrant
agent under this Warrant without any further act. Any such successor warrant
agent shall promptly cause notice of its succession as warrant agent to be
mailed (by first class mail, postage prepaid) to the Holder at the Holder's last
address as shown on the Warrant Register.

the parties hereto and their respective successors and permitted assigns. This
Warrant may be amended only in writing signed by the Company and the Holder.

               (b)  Subject to Section 11(a), above, nothing in this Warrant
shall be construed to give to any person or corporation other than the Company
and the Holder any legal or equitable right, remedy or cause under this Warrant;
this Warrant shall be for the sole and exclusive benefit of the Company and the
Holder.

               (c)  This Warrant shall be governed by and construed and enforced
in accordance with the internal laws of the State of Delaware without regard to
the principles of conflicts of law thereof.

               (d)  The headings herein are for convenience only, do not
constitute a part of this Warrant and shall not be deemed to limit or affect any
of the provisions hereof.

               (e)  In case any one or more of the provisions of this Warrant
shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Warrant shall not
in any way be affected or impaired thereby and the parties will attempt in good
faith to agree upon a valid and enforceable provision which shall be a
commercially reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Warrant.
