                            VOID AFTER         , 2001


                          GABRIEL COMMUNICATIONS, INC.

                               WARRANT CERTIFICATE


                  THIS CERTIFIES THAT for value received         , or registered
assigns, is the owner of the number of Warrants set forth above, each of which
entitles the owner thereof to purchase, subject to the terms of this Warrant
Certificate, upon presentation and surrender of this Warrant Certificate with
the Form of Election to Purchase attached hereto duly executed, at any time
prior to the Expiration Date (as defined below), at the principal executive
offices of Gabriel Communications, Inc., a Delaware corporation (the "Company")
one fully paid and nonassessable share of the Common Stock, $.01 par value
("Common Stock") of the Company at the purchase price of $6.00 per share
("Purchase Price"), payable in cash, except as provided below. The Expiration
Date shall be the earlier of (a) 4:00 P.M. (St. Louis time) on           , 2001,
or (b) subject to receipt of the Offering Notice (as defined below) by the
holder of this Warrant Certificate, the closing of the sale of Common Stock in a
firm commitment, underwritten public offering registered under the Securities
Act of 1933, as amended (the "Securities Act"), other than a registration
relating solely to a transaction under Rule 145 under the Securities Act (or any
successor thereto) or to an employee benefit plan of the Company, at a public
offering price (prior to underwriters' discounts and expenses) equal to or
exceeding $12.00 per share of Common Stock (as adjusted for any stock dividends,
combinations or splits with respect to the Common Stock), in which the aggregate
proceeds to the Company and/or any selling stockholders (prior to underwriters'
discounts and expenses) are at least $50,000,000 (a "Qualified Public
Offering"). The Company shall provide written notice (the "Offering Notice") to
the holder of this Warrant Certificate of the proposed closing date of a
Qualified Public Offering (the "Closing Date") not later than 10 days prior to
the actual Closing Date. Upon receipt of the Offering Notice, the holder of this
Warrant Certificate, upon surrender of this Warrant Certificate with the Form of
Election to Purchase attached hereto duly executed, may exercise the Warrants
evidenced hereby conditioned upon the closing of the Qualified Public Offering
described in the Offering Notice (a "Conditional Exercise"). If the Qualified
Public Offering does not close within 30 days of such proposed Closing Date, the
Warrants evidenced hereby shall remain outstanding and this Warrant Certificate
shall be returned to the holder hereof, subject to its prior expiration in
accordance with clause (a), above. If the holder of this Warrant Certificate
exercises the Warrants evidenced hereby conditioned upon the completion of a

<PAGE>   2

Qualified Public Offering then, and only then, may the holder hereof pay the
Purchase Price by delivering to the Company cash and/or shares of Common Stock,
shares of Preferred Stock (as defined below) or other securities (other than the
Warrants evidenced hereby) issued by the Company having a "Market Price" (as
defined in paragraph (ii)(E) below) equal to the amount of the Purchase Price.
These Warrants may be exercised in whole, but not in part, and no fractional
shares of Common Stock will be issued upon exercise of the Warrants evidenced
hereby.

                  The Warrants evidenced by this Warrant Certificate are part of
a series of duly authorized Warrants issued or to be issued under and pursuant
to the terms of an Agreement and Plan of Merger by and among the Company,
Triangle Acquisition, Inc. and State Communications, Inc., dated as of June 9,
2000 (the "Merger Agreement") and are referred to hereinafter as the "$6.00
Warrants." The Merger Agreement also provides for the issuance of additional
$6.00 Warrants of like tenor (the "Additional $6.00 Warrants") and warrants to
purchase Common Stock at a purchase price of $10.25 per share (the "$10.25
Warrants"). The exercise by the holder hereof of the $6.00 Warrants evidenced
hereby shall be deemed to be an exercise of any and all Additional $6.00
Warrants and $10.25 Warrants then held by the holder hereof; provided, however,
that the Company shall not be obligated to issue any of the shares of Common
Stock that may be purchased upon such deemed exercise of the Additional $6.00
Warrants and the $10.25 Warrants until the holder thereof has fully complied
with the terms and conditions thereof, including, but not limited to, the full
payment of the purchase price thereunder prior to the Expiration Date.

                  The number of $6.00 Warrants evidenced by this Warrant
Certificate (and the number of shares of Common Stock which may be purchased
upon exercise hereof) set forth above, and the Purchase Price set forth above,
are the number and Purchase Price as of               , 2000, based on the
shares of Common Stock of the Company as constituted at such date. In order to
prevent dilution of the exercise rights granted under this Warrant, the Purchase
Price shall be subject to adjustment from time to time as follows:

                           (i)  If and whenever on or after the original date of
issuance of this $6.00 Warrant, the Company issues or sells, or in accordance
with subparagraphs (A) or (B) of paragraph (ii) below is deemed to have issued
or sold, any shares of its Common Stock for a consideration per share less than
the Market Price of the Common Stock, then forthwith upon such issue or sale the
Purchase Price shall be reduced to the Purchase Price determined by dividing (A)
the sum of (I) the product derived by multiplying the Purchase Price in effect
immediately prior to such issue or sale times the number of shares of Common
Stock Deemed Outstanding immediately prior to such issue or sale, plus (II) the
consideration, if any, received by the Company upon such issue or sale, by (B)
the number of shares of Common Stock Deemed Outstanding immediately after such
issue or sale; provided that there shall be no adjustment in the Purchase Price
as a result of any issuance or sale (or deemed issuance or sale) of shares of
Common Stock in any of the following transactions: (A) upon conversion of shares
of the Company's Series A Preferred Stock, Series A-1 Preferred Stock, Series B
Preferred Stock; Series C-1 Preferred Stock, Series C-2 Preferred Stock or
Series C-3 Preferred Stock (collectively, the "Preferred Stock"); (B) to
officers, directors or employees of, or consultants or advisers to, the Company
pursuant to stock option or stock purchase plans, warrants or agreements on
terms from time to time approved by the Board of Directors, including, without
limitation, the TriVergent Options (as defined in the Merger Agreement); (C)
upon the issuance or exercise of the $6.00 Warrants, the Additional $6.00
Warrants or the $10.25 Warrants; (D) in connection with acquisitions from time
to time approved by the Board of Directors; and (E) for which adjustment of the
Purchase Price is made pursuant to paragraph (I) or paragraph (J) of clause (ii)
below. Whenever the Purchase Price is adjusted, the holder of this $6.00 Warrant
shall thereafter be entitled to purchase at the new Purchase Price the number of
shares of Common

                                       2

<PAGE>   3


Stock obtained by multiplying the Purchase Price in effect immediately prior to
such adjustment by the number of shares of Common Stock purchasable pursuant
hereto immediately prior to such adjustment and dividing the product thereof by
the new Purchase Price. As used herein, the term "Common Stock Deemed
Outstanding" means, at any given time, the number of shares of Common Stock
actually outstanding at such time, plus the number of shares of Common Stock
deemed to be outstanding pursuant to subparagraphs (A) and (B) of paragraph (ii)
below.

                           (ii)  For purposes of determining the adjusted
Purchase Price, the following shall be applicable:

                                    (A)  Issuance of Rights or Options.  If and
whenever on or after the original date of issuance of this $6.00 Warrant the
Company in any manner grants any rights or options to subscribe for or to
purchase Common Stock or any stock or other securities convertible into or
exchangeable for Common Stock (such rights or options being herein called
"Options" and such convertible or exchangeable stock or securities being herein
called "Convertible Securities") and the price per share for which Common Stock
is issuable upon the exercise of such Options or upon conversion or exchange of
such Convertible Securities is less than the Market Price at the time of the
granting of such Options, then the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon conversion or exchange
of the total maximum amount of such Convertible Securities shall be deemed to be
outstanding and to have been issued and sold by the Company at the time of the
granting of such Options for such price per share. For purposes of this
paragraph, the "price per share for which Common Stock is issuable" shall be
determined by dividing (I) the total amount, if any, received or receivable by
the Company as consideration for the granting of such Options, plus the minimum
aggregate amount of additional consideration payable to the Company upon
exercise of all such Options, plus in the case of such Options which relate to
Convertible Securities, the minimum aggregate amount of additional consideration
if any, payable to the Company upon the issuance or sale of such Convertible
Securities and the conversion or exchange thereof, by (II) the total maximum
number of shares of Common Stock issuable upon the exercise of such Options or
upon the conversion or exchange of all such Convertible Securities issuable upon
the exercise of such Options. No further adjustment of the Purchase Price shall
be made when Convertible Securities are actually issued upon the exercise of
such Options or when Common Stock is actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities.

                                    (B)  Issuance of Convertible Securities.  If
and whenever on or after the original date of issuance of this $6.00 Warrant the
Company in any manner issues or sells any Convertible Securities and the price
per share for which Common Stock is issuable upon such conversion or exchange of
such Convertible Securities is less than the Market Price at the time of such
issue or sale, then the maximum number of shares of Common Stock issuable upon
conversion or exchange of such Convertible Securities shall be deemed to be
outstanding and to have been issued and sold by the Company at the time of the
issuance or sale of such Convertible Securities for such price per share. For
the purposes of this paragraph, the "price per share for which Common Stock is
issuable" shall be determined by dividing (I) the total amount received or
receivable by the Company as consideration for the issue or sale of such
Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange
thereof, by (II) the total maximum number of shares of Common Stock issuable
upon the conversion or exchange of all such Convertible Securities. No further
adjustment of the Purchase Price shall be made when Common Stock is actually
issued upon the conversion or exchange of such Convertible Securities, and if
any such issue or sale of such Convertible Securities is made upon exercise of
any Options for which adjustments of the Purchase Price had been or are to be
made pursuant to other provisions hereof, no further


                                       3

<PAGE>   4

adjustment of the Purchase Price shall be made by reason of such issue or sale.

                                    (C)  Change in Option Price or Conversion
Rate. If the exercise price provided for in any Options, the additional
consideration, if any, payable upon the conversion or exchange of any
Convertible Securities, or the rate at which any Convertible Securities are
convertible into or exchangeable for Common Stock change at any time, the
Purchase Price in effect at the time of such change shall be readjusted to the
Purchase Price, which would have been in effect at such time had such Options or
Convertible Securities provided for such changed exercise price, additional
consideration or changed conversion rate, as the case may be, at the time
initially granted, issued or sold; provided that if such adjustment would result
in an increase of the Purchase Price then in effect, such adjustment shall not
be effective until 30 days after written notice thereof has been given by the
Company to the holder of this $6.00 Warrant.

                                    (D)  Treatment of Expired Options and
Unexercised Convertible Securities. Upon the expiration of any Option or the
termination of any right to convert or exchange any Convertible Security without
the exercise of any such Option or right, the Purchase Price then in effect
hereunder shall be adjusted to the Purchase Price, which would have been in
effect at the time of such expiration or termination had such Option or
Convertible Security, to the extent outstanding immediately prior to such
expiration or termination, never been issued; provided that if such expiration
or termination would result in an increase in the Purchase Price then in effect,
such increase shall not be effective until 30 days after written notice thereof
has been given to the holder of this $6.00 Warrant.

                                    (E)  Calculation of Consideration Received.
If any Common Stock, Options or Convertible Securities are issued or sold or
deemed to have been issued or sold for cash, the consideration received therefor
shall be deemed to be the net amount received by the Company therefor. In case
any Common Stock, Options or Convertible Securities are issued or sold or deemed
to have been issued or sold for consideration other than cash, the amount of the
consideration other than cash received by the Company shall be the fair value of
such consideration, except where such consideration consists of securities, in
which case the amount of consideration received by the Company shall be the
Market Price thereof as of the date of receipt. If any Common Stock, Options or
Convertible Securities are issued to the owners of the non-surviving entity in
connection with any merger in which the Company is the surviving corporation,
the amount of consideration therefor shall be deemed to be the fair value of
such portion of the net assets and business of the nonsurviving entity as is
attributable to such Common Stock, Options or Convertible Securities, as the
case may be. The fair value of any consideration other than cash and securities
shall be determined by a majority of the Company's board of directors (including
two-thirds of its Outside Directors). As used herein, the term "Market Price" of
any security means the average of the closing sales prices of such security on
all securities exchanges on which such security may at the time be listed, or,
if there has been no sale on any such exchange on any day, the average of the
highest bid and lowest asked prices on all such exchanges at the end of such
day, or, if on any day such security is not so listed, the average of the
representative bid and asked prices quoted in the NASDAQ System as of 4:00 P.M.,
New York time, or, if on any day such security is not quoted in the NASDAQ
System, the average of the highest bid and lowest asked prices on such day in
the domestic over-the-counter market as reported by the National Quotation
Bureau, Incorporated, or any similar successor organization, in each such case
averaged over a period of 21 days consisting of the day as of which "Market
Price" is being determined and the 20 consecutive business days prior to such
day; provided, however, that, if at any time such security is not listed on any
securities exchange or quoted in the NASDAQ System or the over-the-counter
market, the "Market Price" shall be the fair value thereof determined jointly by
the Company and the holder of this $6.00 Warrant. If such parties

                                       4

<PAGE>   5

are unable to reach agreement within a reasonable period of time, such fair
value shall be determined by an independent appraiser experienced in valuing
securities jointly selected by the Company and the holder of this $6.00 Warrant.
The determination of such appraiser shall be final and binding upon the parties,
and the Company shall pay the fees and expenses of such appraiser.

                                    (F)  Integrated Transactions.  In case any
Option is issued in connection with the issue or sale of other securities of the
Company, together comprising one integrated transaction in which no specific
consideration is allocated to such Option by the parties thereto, the Option
shall be deemed to have been issued for a consideration of $.01.

                                    (G)  Treasury Shares.  The number of shares
of Common Stock outstanding at any given time does not include shares owned or
held by or for the account of the Company or any Subsidiary of the Company, and
the disposition of any shares so owned or held shall be considered an issue or
sale of Common Stock.

                                    (H)  Record Date.  If the Company takes a
record of the holders of Common Stock for the purpose of entitling them (a) to
receive a dividend or other distribution payable in Common Stock, Options or
Convertible Securities or (b) to subscribe for or purchase Common Stock, Options
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 upon the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                                    (I)  Subdivision or Combination of Common
Stock. If the Company at any time subdivides (by any stock split, stock
dividend, recapitalization or otherwise) its outstanding shares of Common Stock
into a greater number of shares, the Purchase Price in effect immediately prior
to such subdivision shall be proportionately reduced, and if the Company at any
time combines (by reverse stock split or otherwise) its outstanding shares of
Common Stock into a smaller number of shares, the Purchase Price in effect
immediately prior to such combination shall be proportionately increased.

                                    (J)  Reorganization, Reclassification,
Consolidation, Merger or Sale. Any reorganization, reclassification,
consolidation, merger, sale of all or substantially all of the Company's assets
to another Person or other transaction which is affected in such a manner that
holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in
exchange for Common Stock is referred to herein as an "Organic Change". Prior to
the consummation of any Organic Change, the Company shall make appropriate
provision to insure that the holder of this $6.00 Warrant shall thereafter have
the right to acquire and receive, in lieu of or in addition to (as the case may
be) the shares of Common Stock immediately theretofore acquirable and receivable
upon the exercise of this $6.00 Warrant, such shares of stock, securities or
assets as such holder would have received in connection with such Organic Change
if the holder of this $6.00 Warrant had exercised this $6.00 Warrant immediately
prior to such Organic Change. In each such case, the Company shall also make
appropriate provision to insure that the adjustment provisions of this $6.00
Warrant shall thereafter continue to apply (including, in the case of any such
consolidation, merger or sale in which the successor entity or purchasing entity
is other than the Company, an immediate adjustment of the Purchase Price to the
value for the Common Stock reflected by the terms of such consolidation, merger
or sale, and a corresponding immediate adjustment in the number of shares of
Common Stock acquirable and receivable upon exercise of this $6.00 Warrant, if
the value so reflected is less than the Purchase Price in effect immediately
prior to such consolidation, merger or sale). The Company shall not effect any
consolidation, merger or sale, unless prior to the consummation thereof, the
successor corporation (if other than the Company)

                                       5

<PAGE>   6


resulting from such consolidation or merger or the corporation purchasing such
assets assumes by written instrument the obligation to deliver to the holder of
this $6.00 Warrant such shares of stock, securities or assets as, in accordance
with the foregoing provisions, such holder may be entitled to acquire.

               (K)  Certain Events.  If any event occurs of the type
contemplated by the adjustment provisions of this $6.00 Warrant but not
expressly provided for by such provisions (including, without limitation, the
granting of stock appreciation rights, phantom stock rights or other rights with
equity features), then the Company's board of directors shall make an
appropriate adjustment in the Purchase Price so as to protect the rights of the
holder of this $6.00 Warrant; provided that no such adjustment shall increase
the Purchase Price as otherwise determined pursuant hereto or decrease the
number of shares of Common Stock issuable upon exercise of this $6.00 Warrant.

               (L)  Notices.  Immediately upon any adjustment of the Purchase
Price, the Company shall give written notice thereof to the holder of this $6.00
Warrant, setting forth in reasonable detail and certifying the calculation of
such adjustment. The Company shall also give written notice to the holder of
this $6.00 Warrant at least 20 days prior to the date on which the Company
closes its books or takes a record (I) with respect to any dividend or
distribution upon the Common Stock, (II) with respect to any pro rata
subscription offer to holders of the Common Stock or (III) for determining
rights to vote with respect to any Organic Change, dissolution or liquidation,
and the date on which any Organic Change shall take place.

               (M)  Purchase Rights.  If at any time the Company grants, issues
or sells any Options, Convertible Securities or rights to purchase stock,
warrants, securities or other property (the "Purchase Rights") pro rata to each
record holder of the Common Stock, in its capacity as such record holder, then
the holder of this $6.00 Warrant shall thereafter be entitled to acquire, in
addition to the shares of Common Stock acquirable and receivable upon exercise
of this $6.00 Warrant, and upon the terms applicable to such Purchase Rights,
the aggregate Purchase Rights which such holder could have acquired if such
holder had held the number of shares of Common Stock acquirable upon exercise of
this $6.00 Warrant immediately before the date on which a record is taken for
the grant, issuance or sale of such Purchase Rights, or, if no such record is
taken, the date as of which the record holders of Common Stock are to be
determined for the grant, issue or sale of such Purchase Rights.

          The Company covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issuance
upon exercise of this $6.00 Warrant, such number of shares of Common Stock as
shall from time to time be issuable upon the exercise of this $6.00 Warrant; and
if at any time the number of authorized but unissued and issued but not
outstanding shares of the Common Stock, on a fully diluted basis, shall not be
sufficient to effect the exercise of this $6.00 Warrant at the Purchase Price
then in effect, the Company will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued or
issued but not outstanding shares of the Common Stock to such number of shares
as shall be sufficient for such purpose. The Company covenants that all shares
of Common Stock which shall be so issuable, when issued upon conversion of this
$6.00 Warrant, shall be duly and validly issued, fully-paid and non-assessable.

          The issuance of certificates for shares of the Common Stock upon the
exercise of this $6.00 Warrant shall be made without charge to the holder hereof
for any issuance tax in respect of the issuance of such certificates or other
cost incurred by the Company in connection with such exercise and the related
issuance of shares of Common Stock.

                                       6

<PAGE>   7

                  No holder of this Warrant Certificate shall be entitled to
vote or receive dividends or be deemed the holder of Common Stock or any other
securities of the Company which may at any time be issuable on the exercise
hereof for any purpose, nor shall anything contained herein be construed to
confer upon the holder hereof, as such, any of the rights of a shareholder of
the Company or any right to vote for the election of directors or upon any
matter submitted to stockholders at any meeting thereof, or to give or withhold
consent to any corporate action (whether upon any recapitalization, issue of
stock, reclassification of stock, change of par value, consolidation, merger,
conveyance, or otherwise), or except as provided above, to receive notice of
meetings, or to receive dividends of subscription rights or otherwise, until the
Warrant or Warrants evidenced by this Warrant Certificate shall have been
exercised.

                  Every holder of this Warrant Certificate by accepting the same
consents and agrees with the Company that:

                           (a) Neither this Warrant Certificate nor any rights
                  hereunder may be assigned, transferred, pledged or
                  hypothecated in any way (whether by operation of law or
                  otherwise) without the express prior written consent of the
                  Company, which consent will be given at the Company's sole
                  discretion; provided, however, that the holder hereof may
                  transfer this Warrant Certificate and the rights hereunder to
                  an Affiliate (as defined below) of such holder without such
                  consent; provided, further, however, that, notwithstanding the
                  foregoing proviso, that any such permitted transfer may be
                  effected only if the Additional $6.00 Warrants and the $10.25
                  Warrants held by the holder of this $6.00 Warrant are
                  transferred to the same transferee as part of the same
                  transfer. This Warrant Certificate shall not be subject to
                  execution, attachment or similar process. Any attempted
                  assignment, transfer, pledge, hypothecation or other
                  disposition of this Warrant Certificate or the rights
                  hereunder contrary to the provisions hereof shall be null and
                  void and without legal effect;

                           (b) This Warrant Certificate, if transferred in
                  accordance with paragraph (a), above, is transferable only on
                  the registry books of the Company if surrendered at the
                  principal office of the Company, duly endorsed, or accompanied
                  by a proper instrument of transfer;

                           (c) The Company may deem and treat the person in
                  whose name the Warrant Certificate is registered as the
                  absolute owner thereof and of the $6.00 Warrants evidenced
                  thereby (notwithstanding any notations of ownership or writing
                  on the Warrant Certificates made by anyone other than the
                  Company) for all purposes whatsoever, and the Company shall
                  not be affected by any notice to the contrary;

                           (d) If this $6.00 Warrant is exercised at any time
                  prior to the closing of a Qualified Public Offering, the
                  holder hereof shall, prior to the delivery of any shares of
                  Common Stock which may be purchased upon exercise hereof,
                  execute and deliver to the Company instruments of accession
                  providing that the holder of such shares shall become a party
