                             STOCK PURCHASE WARRANT

                  To Purchase 600,000 Shares of Common Stock of

                        AQUIS COMMUNICATIONS GROUP, INC.

                 THIS CERTIFIES that, for value received, Coxton, Limited, (the
"Holder"), is entitled, upon the terms and subject to the conditions hereinafter
set forth, at any time on or after May 3, 2000 (the "Issuance Date") and on or
prior to the close of business on May 3, 2003 (the "Termination Date") but not

shares (the "Warrant Shares") of Common Stock, $0.01 par value, of the Company
(the "Common Stock"). The purchase price of one share of Common Stock (the

Purchase Agreement shall control. Capitalized terms used and not otherwise
defined herein shall have the meanings set forth for such terms in the Purchase
Agreement.

                                       1
<PAGE>

                 1. Title to Warrant. Prior to the Termination Date hereof and
subject to compliance with applicable laws, this Warrant and all rights
hereunder are transferable, in whole or in part, at the office or agency of the
Company by the holder hereof in person or by duly authorized attorney, upon
surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed.

                 2. Authorization of Shares. The Company covenants that all
shares of Common Stock which may be issued upon the exercise of rights
represented by this Warrant will, upon exercise of the rights represented by
this Warrant, be duly authorized, validly issued, fully paid and nonassessable
and free from all taxes, liens and charges in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously with
such issue).

                 3. Exercise of Warrant. Except as provided in Section 4 herein,
exercise of the purchase rights represented by this Warrant may be made at any
time or times on or after the Issuance Date hereof, and before the close of
business on the Termination Date hereof. Exercise of this Warrant or any part
hereof shall be effected by the surrender of this Warrant and the Notice of
Exercise Form annexed hereto duly executed, at the office of the Company (or
such other office or agency of the Company as it may designate by notice in
writing to the registered holder hereof at the address of such holder appearing
on the books of the Company) and upon payment of the Exercise Price of the
shares thereby purchased by wire transfer or cashier's check drawn on a United
States bank, the holder of this Warrant shall be entitled to receive a
certificate for the number of shares of Common Stock so purchased. Certificates
for shares purchased hereunder shall be delivered to the holder hereof within
three (3) Trading Days after the date on which this Warrant shall have been
exercised as aforesaid. This Warrant shall be deemed to have been exercised and
such certificate or certificates shall be deemed to have been issued, and Holder
or any other person so designated to be named therein shall be deemed to have
become a holder of record of such shares for all purposes, as of the date the
Warrant has been exercised by payment to the Company of the Exercise Price and
all taxes required to be paid by Holder, if any, pursuant to Section 5 prior to
the issuance of such shares, have been paid. If this Warrant shall have been
exercised in part, the Company shall, at the time of delivery of the certificate
or certificates representing Warrant Shares, deliver to Holder a new Warrant
evidencing the rights of Holder to purchase the unpurchased shares of Common
Stock called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant. If a registration statement permitting the
resale of the Shares issuable upon exercise of this Warrant is not then
effective, this Warrant may also be exercised by means of a "cashless exercise"
in which the holder shall be entitled to receive a certificate for the number of
shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the average of the high and low trading prices per share of Common
Stock on the Trading Day preceding the date of such election;

(B) = the Exercise Price of the Warrants; and

                                       2
<PAGE>

(X) = the number of shares issuable upon exercise of the Warrants in accordance
with the terms of this Warrant.

                 4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the Exercise Price.

                 5. Charges, Taxes and Expenses. Issuance of certificates for
shares of Common Stock upon the exercise of this Warrant shall be made without
charge to the holder hereof for any issue or transfer tax or other incidental
expense in respect of the issuance of such certificate, all of which taxes and
expenses shall be paid by the Company, and such certificates shall be issued in
the name of the holder of this Warrant or in such name or names as may be
directed by the holder of this Warrant; provided, however, that in the event
certificates for shares of Common Stock are to be issued in a name other than
the name of the holder of this Warrant, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly
executed by the holder hereof; and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax
incidental thereto.

                 6. Closing of Books. The Company will not close its shareholder
books or records in any manner which prevents the timely exercise of this
Warrant.

                 7. Transfer, Division and Combination. (a) Subject to
compliance with any applicable securities laws, transfer of this Warrant and all
rights hereunder, in whole or in part, shall be registered on the books of the
Company to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by Holder or its
agent or attorney and funds sufficient to pay any transfer taxes payable upon
the making of such transfer. Upon such surrender and, if required, such payment,
the Company shall execute and deliver a new Warrant or Warrants in the name of
the assignee or assignees and in the denomination or denominations specified in
such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled. A Warrant, if properly assigned, may be exercised by a
new holder for the purchase of shares of Common Stock without having a new
Warrant issued.

                    (b) This Warrant may be divided or combined with other
Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued, signed by Holder or its agent or attorney.
Subject to compliance with Section 7(a), as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver
a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided
or combined in accordance with such notice.

                    (c) The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 7.

                                       3
<PAGE>

                    (d) The Company agrees to maintain, at its aforesaid office,
books for the registration and the registration of transfer of the Warrants.

                         8. No Rights as Shareholder until Exercise. This
Warrant does not entitle the holder hereof to any voting rights or other rights
as a shareholder of the Company prior to the exercise hereof. Upon the surrender
of this Warrant and the payment of the aggregate Exercise Price, the Warrant
Shares so purchased shall be and be deemed to be issued to such holder as the
record owner of such shares as of the close of business on the later of the date
of such surrender or payment.

                                       4
<PAGE>

                 9. Loss, Theft, Destruction or Mutilation of Warrant. The
Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant
certificate or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory
to it (which shall not include the posting of any bond), and upon surrender and
cancellation of such Warrant or stock certificate, if mutilated, the Company
will make and deliver a new Warrant or stock certificate of like tenor and dated
as of such cancellation, in lieu of such Warrant or stock certificate.

                 10. Saturdays, Sundays, Holidays, etc. If the last or appointed
day for the taking of any action or the expiration of any right required or
granted herein shall be a Saturday, Sunday or a legal holiday, then such action
may be taken or such right may be exercised on the next succeeding day not a
Saturday, Sunday or legal holiday.

                 11. Adjustments of Exercise Price and Number of Warrant Shares.
(a) Stock Splits, etc. The number and kind of securities purchasable upon the
exercise of this Warrant and the Exercise Price shall be subject to adjustment
from time to time upon the happening of any of the following. In case the
Company shall (i) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater
number of shares of Common Stock, (iii) combine its outstanding shares of Common
Stock into a smaller number of shares of Common Stock or (iv) issue any shares
of its capital stock in a reclassification of the Common Stock, then the number
of Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the holder of this Warrant shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which he would have owned or have been entitled to receive had such
Warrant been exercised in advance thereof. Upon each such adjustment of the kind
and number of Warrant Shares or other securities of the Company which are
purchasable hereunder, the holder of this Warrant shall thereafter be entitled
to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment. An adjustment made pursuant to
this paragraph shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

                    (b) Reorganization, Reclassification, Merger, Consolidation
or Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then Holder shall


                                       5
<PAGE>

have the right thereafter to receive, upon exercise of this Warrant, the number
of shares of common stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and Other Property receivable upon
or as a result of such reorganization, reclassification, merger, consolidation
or disposition of assets by a holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event. In case of
any such reorganization, reclassification, merger, consolidation or disposition
of assets, the successor or acquiring corporation (if other than the Company)
shall expressly assume the due and punctual observance and performance of each
and every covenant and condition of this Warrant to be performed and observed by
the Company and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate (as determined in good faith by
resolution of the Board of Directors of the Company) in order to provide for
adjustments of shares of Common Stock for which this Warrant is exercisable
which shall be as nearly equivalent as practicable to the adjustments provided
for in this Section 11. For purposes of this Section 11, "common stock of the
successor or acquiring corporation" shall include stock of such corporation of
any class which is not preferred as to dividends or assets over any other class
of stock of such corporation and which is not subject to redemption and shall
also include any evidences of indebtedness, shares of stock or other securities
which are convertible into or exchangeable for any such stock, either
immediately or upon the arrival of a specified date or the happening of a
specified event and any warrants or other rights to subscribe for or purchase
any such stock. The foregoing provisions of this Section 11 shall similarly
apply to successive reorganizations, reclassifications, mergers, consolidations
or disposition of assets.

                 12. Voluntary Adjustment by the Company. The Company may at
any time during the term of this Warrant, reduce the then current Exercise Price
to any amount and for any period of time deemed appropriate by the Board of
Directors of the Company.

                 13. Notice of Adjustment. Whenever the number of Warrant Shares
or number or kind of securities or other property purchasable upon the exercise
of this Warrant or the Exercise Price is adjusted, as herein provided, the
Company shall promptly mail by registered or certified mail, return receipt
requested, to the holder of this Warrant notice of such adjustment or
adjustments setting forth the number of Warrant Shares (and other securities or
property) purchasable upon the exercise of this Warrant and the Exercise Price
of such Warrant Shares (and other securities or property) after such adjustment,
setting forth a brief statement of the facts requiring such adjustment and
setting forth the computation by which such adjustment was made. Such notice, in
the absence of manifest error, shall be conclusive evidence of the correctness
of such adjustment.

                 14. Notice of Corporate Action. If at any time:

                    (a) the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

                    (b) there shall be any capital reorganization of the
Company, any reclassification or recapitalization of the capital stock of the
Company or any consolidation or


                                       6
<PAGE>

merger of the Company with, or any sale, transfer or other disposition of all or
substantially all the property, assets or business of the Company to, another
corporation or,

                    (c) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 30 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 30
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of the Company and
delivered in accordance with Section l6(d).

                 15. Authorized Shares. The Company covenants that during the
period the Warrant is outstanding, it will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance
of the Warrant Shares upon the exercise of any purchase rights under this
Warrant. The Company further covenants that its issuance of this Warrant shall
constitute full authority to its officers who are charged with the duty of
executing stock certificates to execute and issue the necessary certificates for
the Warrant Shares upon the exercise of the purchase rights under this Warrant.
The Company will take all such reasonable action as may be necessary to assure
that such Warrant Shares may be issued as provided herein without violation of
any applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

                    The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant, and (c) use all commercially
reasonable efforts to obtain all such authorizations, exemptions or


                                       7
<PAGE>

consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this Warrant.

                    Upon the request of Holder, the Company will at any time
during the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant and
the obligations of the Company hereunder.

                    Before taking any action which would cause an adjustment
reducing the current Exercise Price below the then par value, if any, of the
shares of Common Stock issuable upon exercise of the Warrants, the Company shall
take any corporate action which may be necessary in order that the Company may
validly and legally issue fully paid and non-assessable shares of such Common
Stock at such adjusted Exercise Price.

                    Before taking any action which would result in an adjustment
in the number of shares of Common Stock for which this Warrant is exercisable or
in the Exercise Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

                 16. Miscellaneous.

                    (a) Jurisdiction. This Warrant shall be binding upon any
successors or assigns of the Company. This Warrant shall constitute a contract
under the laws of New York without regard to its conflict of law principles or
rules, and be subject to arbitration pursuant to the terms set forth in the
Purchase Agreement.

                    (b) Restrictions. The holder hereof acknowledges that the
Warrant Shares acquired upon the exercise of this Warrant, if not registered,
will have restrictions upon resale imposed by state and federal securities laws.

                    (c) Nonwaiver and Expenses. No course of dealing or any
delay or failure to exercise any right hereunder on the part of Holder shall
operate as a waiver of such right or otherwise prejudice Holder's rights, powers
or remedies, notwithstanding all rights hereunder terminate on the Termination
Date hereof. If the Company willfully fails to comply with any material
provision of this Warrant, the Company shall pay to Holder such amounts as shall
be sufficient to cover any costs and expenses including, but not limited to,
reasonable attorneys' fees, including those of appellate proceedings, incurred
by Holder in collecting any amounts due pursuant hereto or in otherwise
enforcing any of its rights, powers or remedies hereunder.

                    (d) Notices. Any notice, request or other document required
or permitted to be given or delivered to the holder hereof by the Company shall
be delivered in accordance with the notice provisions of the Purchase Agreement.

                    (e) Limitation of Liability. No provision hereof, in the
absence of affirmative action by Holder to purchase shares of Common Stock, and
no enumeration herein of the rights or privileges of Holder hereof, shall give
rise to any liability of Holder for the purchase


                                       8
<PAGE>

price of any Common Stock or as a stockholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

                    (f) Remedies. Holder, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant. The Company
agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and
hereby agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate.

                    (g) Successors and Assigns. Subject to applicable securities
laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors of the Company and the
successors and permitted assigns of Holder. The provisions of this Warrant are
intended to be for the benefit of all Holders from time to time of this Warrant
and shall be enforceable by any such Holder or holder of Warrant Shares.

                    (h) Indemnification. The Company agrees to indemnify and
hold harmless Holder from and against any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, claims, costs, attorneys' fees,
expenses and disbursements of any kind which may be imposed upon, incurred by or
asserted against Holder in any manner relating to or arising out of any failure
by the Company to perform or observe in any material respect any of its
covenants, agreements, undertakings or obligations set forth in this Warrant;
provided, however, that the Company will not be liable hereunder to the extent
that any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, attorneys' fees, expenses or disbursements are
found in a final non-appealable judgment by a court to have resulted from
Holder's negligence, bad faith or willful misconduct in its capacity as a
stockholder or warrantholder of the Company.

                    (i) Amendment. This Warrant may be modified or amended or
the provisions hereof waived with the written consent of the Company and the
Holder.

                    (j) Severability. Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

                    (k) Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.
