to Premiere's Second Amended and Restated 1995 Stock Plan (the "Stock Plan

To the Stockholders of
 Premiere Technologies, Inc.:
   
  NOTICE IS HEREBY GIVEN that a special meeting of stockholders ("Special
Meeting") of Premiere Technologies, Inc. ("Premiere") will be held at the
Terrace Garden Inn, 3405 Lenox Road, N.E., Atlanta, Georgia 30326, at 10:00

    1. Issuance of Shares of Premiere Common Stock Pursuant to the Merger
  Agreement. To consider and vote upon a proposal to approve the issuance of
  shares of the common stock, par value $.01 per share, of Premiere
  ("Premiere Common Stock") pursuant to an Agreement and Plan of Merger,
  dated as of November 13, 1997 (the "Merger Agreement"), by and among
  Premiere, Nets Acquisition Corp., a wholly owned subsidiary of Premiere
  ("Acquisition Sub"), and Xpedite Systems, Inc. ("Xpedite"), pursuant to
  which, among other matters, Acquisition Sub will merge with and into
  Xpedite (the "Merger"). If the proposed Merger is consummated, Xpedite will
  become a wholly owned subsidiary of Premiere and each outstanding share of
  the common stock, par value $.01 per share, of Xpedite (excluding shares
  held by Xpedite in its treasury) will be converted into the right to
  receive shares of Premiere Common Stock, as more fully described in the
  accompanying Joint Proxy Statement/Prospectus. A copy of the Merger
  Agreement is set forth in Annex A to the accompanying Joint Proxy
  Statement/Prospectus and is hereby incorporated by reference herein.
 
    2. Stock Plan Amendment. To consider and vote upon a proposal to approve
  an amendment to Premiere's Second Amended and Restated 1995 Stock Plan (the
  "Stock Plan Amendment"), which will increase the number of shares of
  Premiere Common Stock reserved for issuance from 4,000,000 to 8,000,000.
 
    3. Other Business. To transact such other business as may properly come
  before the Special Meeting or any adjournments or postponements thereof.
   
  Only holders of record of Premiere Common Stock and the outstanding share of

the close of business on Friday, January 23, 1998 (the "Record Date"), are
entitled to receive notice of and to vote at the Special Meeting or any
adjournments or postponements thereof. Holders of Premiere Common Stock are
entitled to one vote on each matter considered and voted on at the Special
Meeting for each share of Premiere Common Stock held of record at the close of
business on the Record Date. The holder of the outstanding share of the
Premiere Preferred Stock is entitled to the number of votes that the holders
of the shares of exchangeable non-voting shares of Voice-Tel Canada Limited, a
subsidiary of Premiere (the "Exchangeable Shares") would be entitled to cast
if all such Exchangeable Shares were exchanged. The presence in person or by
proxy of a majority of the votes entitled to be cast by holders of Premiere
Common Stock and Premiere Preferred Stock constitute a quorum, and the
issuance of shares of Premiere Common Stock pursuant to the Merger Agreement
and the Stock Plan Amendment must be approved by a majority of the votes cast
at the Special Meeting.

Dear Stockholder:
   
  You are cordially invited to attend a special meeting of stockholders (the
"Special Meeting") of Xpedite Systems, Inc. ("Xpedite") to be held at the
Sheraton Eatontown Hotel and Conference Center, Route 35 & Industrial Way
East, Eatontown, New Jersey 07724, at 10:00 a.m., local time, on February 27,
1998.     
   
  At the Special Meeting, you will be asked to consider and vote upon a
proposal to adopt the Agreement and Plan of Merger, dated as of November 13,
1997 (the "Merger Agreement"), by and among Premiere Technologies, Inc.
("Premiere"), Nets Acquisition Corp., a wholly owned subsidiary of Premiere
("Acquisition Sub"), and Xpedite, which provides for the merger (the "Merger")
of Acquisition Sub with and into Xpedite. If the proposed Merger is
consummated, Xpedite will become a wholly owned subsidiary of Premiere and
each outstanding share of common stock, par value $.01 per share, of Xpedite
("Xpedite Common Stock") (excluding shares held by Xpedite in its treasury)
will be converted into the right to receive that multiple (the "Exchange
Ratio") of a share of the common stock, par value $.01 per share, of Premiere
("Premiere Common Stock") equal to $34.00 divided by the average of the daily
last sale prices for the shares of Premiere Common Stock for the 20
consecutive trading days on which such shares are actually traded as over-the-
counter securities and quoted on the Nasdaq National Market (as reported by
The Wall Street Journal or, if not reported thereby, any other authoritative
source selected by Premiere and Xpedite) ending at the close of trading on the
trading day immediately preceding the date of the Special Meeting (the
"Average Closing Price"); provided, that for purposes of such conversion, the
Average Closing Price shall be deemed to equal $27.20 in the event the actual
Average Closing Price is less than $27.20, and shall be deemed to equal $39.20
in the event the actual Average Closing Price is greater than $39.20. As
further described in the accompanying Joint Proxy Statement/Prospectus, the
Board of Directors of Xpedite (the "Xpedite Board") has the right to terminate
the Merger Agreement if the actual Average Closing Price is below $24.00
("Threshold Price"), unless the Board of Directors of Premiere (the "Premiere
Board") elects to increase the Exchange Ratio as provided in the Merger
Agreement. It is not possible to know if the Average Closing Price will be
less than the Threshold Price until the day immediately preceding the date of
the Special Meeting. Since the date of the Merger Agreement, the market price
of Premiere Common Stock has been subject to significant fluctuation, with the
high and low closing price therefor ranging from $28 11/16 to $21 7/8. On
January 27, 1998, the closing price of Premiere Common Stock was $24 1/4. A
copy of the Merger Agreement is set forth in Annex A to the accompanying Joint
Proxy Statement/Prospectus.     
 
  Enclosed are (i) a Notice of Special Meeting, (ii) a Joint Proxy
Statement/Prospectus, and (iii) a form of proxy for the Special Meeting. The
Joint Proxy Statement/Prospectus describes in more detail the Merger Agreement
and the Merger, including a description of the conditions to consummation of
the Merger and the effects of the Merger on the rights of Xpedite
stockholders, and contains financial and other information about Premiere and
Xpedite.
 
  Please give this information your careful attention.
   
  Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"),
Xpedite's financial advisor, has rendered its written opinion (the "Merrill
Lynch Opinion") to Xpedite's Board of Directors that, as of November 13, 1997,
the Merger Consideration (as defined in the attached Joint Proxy
Statement/Prospectus) is fair to the holders of Xpedite Common Stock from a
financial point of view. The full text of the written opinion of Merrill
Lynch, which sets forth the assumptions made, matters considered, and
qualifications and limitations on the review undertaken by Merrill Lynch, is
set forth in Annex B to the accompanying Joint Proxy Statement/Prospectus and
Xpedite stockholders are urged to read such opinion in its entirety. The
Merrill Lynch Opinion is based on the conditions in effect at the time the
parties executed the Merger Agreement. Xpedite     

<PAGE>
 
   
shareholders should note that Merrill Lynch assumed that Xpedite would not
consummate the Merger under circumstances where the Xpedite Board has the
right to terminate the Merger Agreement because the actual Average Closing
Price is below the Threshold Price and therefore such opinion would be
inapplicable under such circumstances. Accordingly, the Merrill Lynch Opinion
does not address the circumstances that might arise if the Xpedite Board has
decided to consummate the Merger in a case where the Threshold Price
termination right is exercisable but the Premiere Board has chosen not to
increase the Exchange Ratio. Likewise, the fairness opinion received by
Premiere does not address the circumstance where the Average Closing Price is
below the Threshold Price and the Premiere Board chooses to increase the
Exchange Ratio. While the Xpedite Board currently intends to exercise its
right to terminate the Merger Agreement if the Average Closing Price is less
than the Threshold Price, it has not made a final determination and it is not
obligated to exercise such right and the final decision as to whether it would
exercise such right in such event, or to withdraw notice of termination as
provided in the Merger Agreement, would be made at the time the termination
right becomes exercisable or in the event that the Premiere Board declines to
increase the Exchange Ratio, as applicable. While the Premiere Board has
indicated that it does not currently intend to increase the Exchange Ratio in
the event Xpedite elects to exercise its termination right, its final decision
whether to increase the Exchange Ratio would be made if and when Xpedite were
to exercise its termination right. In considering whether to exercise their
respective rights in each situation, each of the Xpedite and the Premiere
Boards would, consistent with its fiduciary duties, take into account all
relevant facts and circumstances that exist at such time and would consult
with its respective financial advisors and legal counsel. Approval of the
Merger Agreement by the stockholders of Xpedite at the Special Meeting and
approval of the issuance of shares of Premiere Common Stock pursuant to the
Merger Agreement by the stockholders of Premiere at the special meeting of
Premiere stockholders will confer on the Xpedite Board and the Premiere Board,
respectively, the power, consistent with the fiduciary duties of such boards,
to elect to consummate the Merger if the average closing price is less than
the Threshold Price (in the case of the Xpedite Board) or to elect to increase
the Exchange Ratio in the event Xpedite elects to exercise its termination
right (in the case of the Premiere Board) without any further action by, or
resolicitation of, the stockholders of Xpedite and Premiere, as the case may
be.     
   
  XPEDITE'S BOARD OF DIRECTORS HAS DETERMINED THAT THE MERGER IS FAIR TO AND
IN THE BEST INTERESTS OF XPEDITE AND ITS STOCKHOLDERS AND, ACCORDINGLY, HAS
UNANIMOUSLY APPROVED AND ADOPTED THE MERGER AGREEMENT AND UNANIMOUSLY
RECOMMENDS THAT YOU VOTE FOR ADOPTION OF THE MERGER AGREEMENT.     
 
  In view of the importance of the action to be taken, we urge you to
complete, sign, and date the enclosed proxy and to return it promptly in the
enclosed envelope, whether or not you plan to attend the Special Meeting (if
you attend the Special Meeting, you may vote in person, even if you previously
returned your proxy).

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                 
              TO BE HELD AT 10:00 A.M. ON FEBRUARY 27, 1998     
 
To the Stockholders of Xpedite Systems, Inc.:
   
  NOTICE IS HEREBY GIVEN that a special meeting of stockholders (the "Special
Meeting") of Xpedite Systems, Inc. ("Xpedite") will be held at the Sheraton
Hotel and Eatontown Conference Center, Route 35 & Industrial Way East,
Eatontown, New Jersey 07724, at 10:00 a.m., local time, on February 27, 1998,
for the following purposes:     
     
    1. The Merger. To consider and vote upon a proposal to adopt the
  Agreement and Plan of Merger, dated as of November 13, 1997 (the "Merger
  Agreement"), by and among Xpedite, Premiere Technologies, Inc. ("Premiere")
  and Nets Acquisition Corp., a wholly owned subsidiary of Premiere
  ("Acquisition Sub"), pursuant to which, among other matters, Acquisition
  Sub will merge with and into Xpedite (the "Merger"). If the proposed Merger
  is consummated, Xpedite will become a wholly owned subsidiary of Premiere
  and each outstanding share of common stock, par value $.01 per share, of
  Xpedite ("Xpedite Common Stock") (excluding shares held by Xpedite in its
  treasury) will be converted into the right to receive that multiple (the
  "Exchange Ratio") of a share of the common stock, par value $.01 per share,
  of Premiere ("Premiere Common Stock") equal to $34.00 divided by the
  average of the daily last sale prices for the shares of Premiere Common
  Stock for the 20 consecutive trading days on which such shares are actually
  traded as over-the-counter securities and quoted on the Nasdaq National
  Market (as reported by The Wall Street Journal or, if not reported thereby,
  any other authoritative source selected by Premiere and Xpedite) ending at
  the close of trading on the trading day immediately preceding the date of
  the Special Meeting (the "Average Closing Price"); provided, that for
  purposes of such conversion, the Average Closing Price shall be deemed to
  equal $27.20 in the event the actual Average Closing Price is less than
  $27.20, and shall be deemed to equal $39.20 in the event the actual Average
  Closing Price is greater than $39.20. As further described in the
  accompanying Joint Proxy Statement/Prospectus, the Board of Directors of
  Xpedite has the right to terminate the Merger Agreement if the actual
  Average Closing Price is below $24.00, unless Premiere elects to increase
  the Exchange Ratio as provided in the Merger Agreement. Since the date of
  the Merger Agreement, the market price of Premiere Common Stock has been
  subject to significant fluctuation, with the high and low closing price
  therefor ranging from $28 11/16 to $21 7/8. On January 27, 1998, the
  closing price of Premiere Common Stock was $24 1/4 A copy of the Merger
  Agreement is set forth in Annex A to the accompanying Joint Proxy
  Statement/Prospectus.     
 
    2. Other Business. To transact such other business as may properly come
  before the Special Meeting or any adjournments or postponements thereof.
   
  Only stockholders of record at the close of business on Friday, January 23,
1998 (the "Record Date"), are entitled to receive notice of and to vote at the
Special Meeting or any adjournments or postponements thereof. Holders of
Xpedite Common Stock are entitled to one vote on each matter considered and
voted on at the Special Meeting for each share of Xpedite Common Stock held of
record at the close of business on the Record Date. The presence in person or
by proxy of a majority of the outstanding votes entitled to be cast by holders
of Xpedite Common Stock will constitute a quorum, and approval of the Merger
Agreement requires the affirmative vote of a majority of votes of the
outstanding Xpedite Common Stock entitled to vote thereon. The holders of an
aggregate of 2,976,941 shares of Xpedite Common Stock (32.8% of the
outstanding shares as of the Record Date) have agreed to vote the shares of
Xpedite Common Stock owned by them in favor of adoption of the Merger
Agreement.     
 
  THE BOARD OF DIRECTORS OF XPEDITE HAS DETERMINED THAT THE MERGER IS FAIR TO
AND IN THE BEST INTERESTS OF XPEDITE AND ITS STOCKHOLDERS. THE BOARD OF
DIRECTORS OF XPEDITE UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE "FOR"
ADOPTION OF THE MERGER AGREEMENT.
 
  HOLDERS OF XPEDITE COMMON STOCK SHOULD NOT SEND IN THEIR CERTIFICATES
REPRESENTING SHARES OF XPEDITE COMMON STOCK UNTIL THEY RECEIVE THE LETTER OF
TRANSMITTAL, WHICH WILL BE SENT TO FORMER HOLDERS OF XPEDITE COMMON STOCK AS
SOON AS PRACTICABLE FOLLOWING THE CONSUMMATION OF THE MERGER AND THE FILING OF
THE CERTIFICATE OF MERGER WITH THE SECRETARY OF STATE OF DELAWARE.
 
  BY ORDER OF THE BOARD OF DIRECTORS
                                                  
                                               /s/ Robert S. Vaters

                                    SUMMARY
 
  The following is a summary of certain information contained elsewhere in this
Joint Proxy Statement/Prospectus. This summary is not intended to be a complete
description of the matters covered in this Joint Proxy Statement/Prospectus and
is subject to and qualified in its entirety by reference to the more detailed
information contained elsewhere in this Joint Proxy Statement/Prospectus,
including the Annexes hereto, and in the documents incorporated by reference in
this Joint Proxy Statement/Prospectus. The Merger Agreement is set forth in
Annex A to this Joint Proxy Statement/Prospectus, and reference is made thereto
for a complete description of the terms of the Merger. Stockholders are urged
to read carefully the entire Joint Proxy Statement/Prospectus, including the
Annexes. As used in this Joint Proxy Statement/Prospectus, the terms "Premiere"
and "Xpedite" refer to such corporations, respectively, and where the context
requires, such corporations and their respective subsidiaries.
 
PARTIES TO THE MERGER
   
  Xpedite. Xpedite is a Delaware corporation that provides a wide range of
computer and fax-based services focused primarily on high volume electronic
document distribution. Xpedite is the leading independent worldwide provider of
enhanced fax services, and a leading provider of discounted international fax
services via a worldwide network with points of presence ("POPs") in over 70
cities in approximately 29 countries and over 14,500 fax lines. Xpedite also
provides telex, Internet e-mail and mailgram services. Xpedite's principal
executive offices are located at One Industrial Way West, Eatontown, New Jersey
07724; telephone number (732) 389-3900.     
   
  In addition to the Merger Agreement described herein, pursuant to a Share
Purchase Agreement, dated as of August 8, 1997 (the "XSL Purchase Agreement"),
among Xpedite, Xpedite Systems Holdings (UK) Limited, a newly formed and wholly
owned subsidiary of Xpedite ("XSL Acquisition Corp."), and the shareholders of
Xpedite Systems Limited, an English corporation ("XSL"), XSL Acquisition Corp.
purchased all the share capital of XSL for a purchase price of approximately
$85.5 million, (the "XSL Acquisition"). The closing of the XSL Acquisition,
which occurred on December 17, 1997, was a condition to the closing of the
Merger. Pursuant to (i) a Share Purchase Agreement (the "APAX Purchase
Agreement"), dated as of December 19, 1997, by and among Xpedite, Xpedite
Systems Worldwide, Inc., a Delaware corporation and a wholly owned subsidiary
of Xpedite ("Worldwide"), and APA German European Ventures Limited Partnership,
a Delaware limited partnership, and (ii) a Share Purchase and Option Agreement
(the "XSG Purchase Agreement", and together with the APAX Purchase Agreement,
the "Xpedite Germany Purchase Agreements"), dated as of December 19, 1997, by
and among Xpedite, Worldwide and certain shareholders of Xpedite Systems GmbH,
a German corporation ("Xpedite Germany"), Xpedite has acquired, directly or
indirectly, approximately 76.7% of the issued share capital of Xpedite Germany
and indebtedness of Xpedite Germany to its former majority shareholder for an
aggregate purchase price of approximately $13.2 million. This transaction
closed on January 2, 1998. Together with the 19.9% of the issued share capital
of Xpedite Germany previously owned by Xpedite, Xpedite currently owns
approximately 96.6% of the issued share capital of Xpedite Germany. In
addition, pursuant to the XSG Purchase Agreement, Xpedite has acquired an
option to purchase the remaining 3.4% of the issued share capital of Xpedite
Germany, exercisable at any time after February 15, 1998 at a purchase price of
approximately $600,000.

Reference," and "Description of Xpedite."
 
  Premiere. Premiere is a Georgia corporation that designs, develops, markets
and provides enhanced personal communications services. Premiere's network-
based computer telephony technology links together two or more stand-alone
communications services, such as calling card long distance, voice mail, e-
mail, fax mail and paging, and allows access to these services through
telephones or computers. Premiere bundles these stand-alone services to allow
users to store, manage, prioritize, deliver and distribute incoming and
outgoing information in an easy, efficient and economical manner. Although
Premiere offers stand-alone communications services, it primarily targets users
who have multiple communications devices and a need to integrate them for
 
                                       1

greater functionality and convenience. Premiere's principal executive offices
are located at 3399 Peachtree Road, N.E., Lenox Building, Suite 700, Atlanta,
Georgia 30326; telephone number (404) 262-8400. See "Available Information,"
"Incorporation of Certain Information by Reference," and "Description of
Premiere."     
 
 
  Nets Acquisition Corp. Acquisition Sub is a Delaware corporation and a wholly
owned subsidiary of Premiere that was incorporated in November 1997 solely as a
vehicle to facilitate the Merger. See "The Merger."
 
XPEDITE SPECIAL MEETING; RECORD DATE; VOTE REQUIRED; RECOMMENDATION
   
  The Xpedite Special Meeting will be held at 10:00 a.m., local time on
February 27, 1998, at the Sheraton Eatontown Hotel and Conference Center, Route
35 & Industrial Way East, Eatontown, New Jersey 07724. At the Xpedite Special
Meeting, Xpedite's stockholders will consider and vote upon a proposal to adopt
the Merger Agreement and transact such other business as may properly come
before the Xpedite Special Meeting. See "The Merger." Xpedite's Board of
Directors has fixed the close of business on January 23, 1998, as the record
date for determining the Xpedite stockholders entitled to receive notice of and
to vote at the Xpedite Special Meeting (the "Xpedite Record Date"). As of the
close of business on the Xpedite Record Date, there were 9,083,473 shares of
Xpedite Common Stock outstanding and entitled to be voted at the Xpedite
Special Meeting. Holders of Xpedite Common Stock are entitled to one vote on
each matter considered and voted on at the Xpedite Special Meeting for each
share of Xpedite Common Stock held of record at the close of business on the
Xpedite Record Date.     
   
  The presence in person or by proxy of a majority of the votes entitled to be
cast at the Xpedite Special Meeting by holders of Xpedite Common Stock will
constitute a quorum for purposes of conducting business at the Xpedite Special
Meeting. The affirmative vote of the majority of the outstanding shares of
Xpedite Common Stock entitled to vote thereon will be required for adoption of
the Merger Agreement. The failure to submit a proxy card (or vote in person at
the Xpedite Special Meeting) or the abstention from voting by an Xpedite
stockholder (including broker non-votes) will have the same effect as an
"against" vote with respect to approval of the Merger Agreement. Proxies that
do not contain any instruction to vote for or against adoption of the Merger
Agreement will be voted in favor of such matter. Pursuant to Stockholder
Agreements, each dated as of November 13, 1997 (the "Stockholder Agreements"),
by and among Premiere, Xpedite and each of the holders of Xpedite Common Stock
signatory thereto (the "Locked-Up Stockholders"), the Locked-Up Stockholders
have agreed to vote the shares of Xpedite Common Stock owned by the Locked-Up
Stockholders on the Xpedite Record Date in favor of the adoption of the Merger
Agreement. See "The Merger--Stockholder Agreements." As of the Xpedite Record
Date, the Locked-Up Stockholders held of record an aggregate of 2,976,941
shares of Xpedite Common Stock, representing approximately 32.8% of the
outstanding Xpedite Common Stock. As of the Xpedite Record Date, directors and
executive officers of Xpedite and their affiliates held approximately 29.6% of
the shares of Xpedite Common Stock outstanding and entitled to vote at the
Xpedite Special Meeting. As of the Xpedite Record Date, Premiere, its directors
and executive officers, and their respective affiliates held no shares of
Xpedite Common Stock. For additional information with respect to the Xpedite
Special Meeting, including the Xpedite Record Date and votes required for
adoption of the Merger Agreement, see "General Information--Xpedite Special
Meeting."     
 
  The Board of Directors of Xpedite (the "Xpedite Board") (other than Roy B.
Andersen, Jr. who due to a potential conflict of interest did not attend the
Xpedite Board meeting at which the Merger was voted upon, or vote for the
Merger) believes that the Merger is fair to and in the best interests of
Xpedite and its stockholders and has unanimously approved the Merger Agreement
and the consummation of the transactions contemplated therein. Accordingly, the
Xpedite Board recommends that the stockholders of Xpedite vote FOR adoption of
the Merger Agreement. In deciding to approve the Merger Agreement and the
consummation of the transactions contemplated therein, the Xpedite Board
considered a number of factors, including the terms of the Merger, the
compatibility of the operations of Xpedite and Premiere, the financial
condition, results of operations, and future
 
                                       2

prospects of Xpedite and Premiere, and the opinion of Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("Merrill Lynch"), financial advisor to the Xpedite
Board of Directors, that, as of November 13, 1997, the Merger Consideration (as
defined in "Summary--Merger,") was fair, from a financial point of view, to the
holders of Xpedite Common Stock. The full text of the written opinion of
Merrill Lynch, which sets forth the assumptions made, matters considered, and
qualifications and limitations on the review undertaken by Merrill Lynch, is
attached as Annex B hereto and Xpedite stockholders are urged to read such
opinion in its entirety. See "The Merger--Reasons for the Merger; Xpedite" and
"The Merger--Opinions of Financial Advisors; Xpedite."
 
PREMIERE SPECIAL MEETING; RECORD DATE; VOTES REQUIRED; RECOMMENDATION
   
  The Premiere Special Meeting will be held at 10:00 a.m., local time on
February 27, 1998, at the Terrace Garden Inn, 3405 Lenox Road, N.E., Atlanta,
Georgia 30326. At the Premiere Special Meeting, Premiere's stockholders will
consider and vote upon proposals to approve (1) the issuance of shares of
Premiere Common Stock pursuant to the Merger Agreement, and (2) the Stock Plan
Amendment, and will transact such other business as may properly come before
the Premiere Special Meeting. See "The Merger" and "Stock Plan Amendment."
Premiere's Board of Directors has fixed the close of business on January 23,
1998, as the record date for determining the Premiere stockholders entitled to
receive notice of and to vote at the Premiere Special Meeting (the "Premiere
Record Date"). As of the close of business on the Premiere Record Date, there
were 33,966,198 shares of Premiere Common Stock outstanding and entitled to be
voted at the Premiere Special Meeting. Holders of Premiere Common Stock are
entitled to one vote on each matter considered and voted on at the Premiere
Special Meeting for each share of Premiere Common Stock held of record at the
close of business on the Premiere Record Date. As of the close of business on
the Premiere Record Date, there was one share of the Premiere "Series B Voting
Preferred Stock" (the "Premiere Preferred Stock") outstanding and entitled to
vote at the Premiere Special Meeting. The holder of the outstanding share of
Premiere Preferred Stock is entitled to the number of votes that the holders of
the shares of exchangeable non-voting shares of Voice-Tel Canada Limited, a
subsidiary of Premiere (the "Exchangeable Shares") would be entitled to cast if
all such Exchangeable Shares were exchanged for Premiere Common Stock on a one-
to-one ratio. As of the Premiere Record Date, 329,840 Exchangeable Shares were
outstanding. See "Certain Differences in the Rights of Premiere and Xpedite
Stockholders--Voting Rights."     
   
  The presence in person or by proxy of a majority of the votes entitled to be
cast by holders of Premiere Common Stock and Premiere Preferred Stock will
constitute a quorum for purposes of conducting business at the Premiere Special
Meeting. The affirmative vote of the majority of the votes cast by the holders
of shares of Premiere Common Stock and Premiere Preferred Stock, voting
together as a single class, is required for approval of the issuance of the
shares of Premiere Common Stock pursuant to the Merger Agreement and for
approval of the Stock Plan Amendment. As of the Premiere Record Date,
Premiere's directors and executive officers and their affiliates beneficially
owned approximately 13.7% of the outstanding shares of Premiere Common Stock
and Premiere Preferred Stock entitled to vote at the Premiere Special Meeting.
See "General Information--Premiere Special Meeting."     
 
  The Board of Directors of Premiere believes that both the issuance of shares
of Premiere Common Stock pursuant to the Merger Agreement and the Stock Plan
Amendment are in the best interests of Premiere and its stockholders and has
approved the Merger Agreement and the Stock Plan Amendment. The Premiere Board
of Directors unanimously recommends that the stockholders of Premiere vote FOR
approval of the issuance of shares of Premiere Common Stock pursuant to the
Merger Agreement and FOR approval of the Stock Plan Amendment.
 
  In deciding to approve the Merger Agreement, Premiere's Board of Directors
considered a number of factors, including the terms of the Merger and the
compatibility of the operations of Xpedite and Premiere, the financial
condition, results of operations, and future prospects of Xpedite and Premiere,
and the opinion of Prudential Securities Incorporated ("Prudential Securities")
dated November 12, 1997, to the effect that, as of such date, the consideration
to be paid by Premiere in the Merger was fair to Premiere from a financial
point of view. See "The Merger--Reasons for the Merger; Premiere" and "The
Merger--Opinions of Financial Advisors; Premiere."

THE MERGER
   
  Generally. Subject to the terms and conditions of the Merger Agreement,
Acquisition Sub will merge with and into Xpedite, which will be the surviving
corporation of the Merger and, as a result thereof, will become a wholly owned
subsidiary of Premiere. Upon consummation of the Merger, each outstanding share
of Xpedite Common Stock (excluding shares held by Xpedite in its treasury) will
cease to be outstanding and will be converted into the right to receive a
number of shares of Premiere Common Stock equal to the Exchange Ratio (as
defined herein), with cash being paid in lieu of any fractional share interest
(the "Merger Consideration"). See the "The Merger--Merger Consideration." A
copy of the Merger Agreement is set forth in Annex A to this Joint Proxy
Statement/Prospectus.     
 
  Merger Consideration. The Exchange Ratio shall be determined by dividing
$34.00 by the average of the daily last sale prices for the shares of Premiere
Common Stock as reported on the Nasdaq National Market System ("Nasdaq") for
the 20 consecutive trading days on which such shares are actually traded as
over-the-counter securities on Nasdaq (as reported by The Wall Street Journal
or, if not reported thereby, any other authoritative source selected by
Premiere and Xpedite) ending at the close of trading on the trading day
immediately preceding the date of the Xpedite Special Meeting (the "Average
Closing Price"); provided, that except in certain circumstances (see "The
Merger--Termination and Possible Exchange Ratio Increase"), the Exchange Ratio
will not be higher than 1.25 (corresponding to an Average Closing Price of
$27.20 (the "Minimum Average Closing Price")) or lower than .867 (corresponding
to an Average Closing Price of $39.20 (the "Maximum Average Closing Price")).
See "The Merger--Merger Consideration."
 
  THE MERGER CONSIDERATION IS BASED, IN PART, ON THE AVERAGE CLOSING PRICE, ON
WHICH THE MERGER AGREEMENT HAS PLACED THE LIMITS OF THE MINIMUM AVERAGE CLOSING
PRICE AND THE MAXIMUM AVERAGE CLOSING PRICE. THE PREMIERE COMMON STOCK MAY
EXPERIENCE SIGNIFICANT PRICE AND VOLUME FLUCTUATIONS, WHICH MAY CAUSE THE
ACTUAL AVERAGE CLOSING PRICE TO FALL BELOW THE MINIMUM AVERAGE CLOSING PRICE,
OR TO RISE ABOVE THE MAXIMUM AVERAGE CLOSING PRICE, IN WHICH CASE THE DOLLAR
VALUE OF THE PREMIERE COMMON STOCK THAT THE XPEDITE STOCKHOLDERS WILL RECEIVE
IN THE MERGER MAY BE MORE OR LESS THAN THE VALUE OF THE PREMIERE COMMON STOCK
AS OF THE DATE OF EXECUTION OF THE MERGER AGREEMENT, THE DATE HEREOF, THE DATE
OF THE XPEDITE SPECIAL MEETING, THE DATE OF RECEIPT OF SHARES OF PREMIERE
COMMON STOCK BY HOLDERS OF XPEDITE COMMON STOCK, OR THE DATE ON WHICH SUCH
SHARES ARE EVENTUALLY SOLD.
   
  Since the date of the Merger Agreement, the market price of Premiere Common
Stock has been subject to significant fluctuation, with the high and low
closing price therefor ranging from $28 11/16 to $21 7/8. On January 27, 1998,
the closing price of Premiere Common Stock was $24 1/4. See "The Merger--
Termination and Possible Exchange Ratio Increase."     
 
  Effective Time. Assuming satisfaction or waiver (if permitted) of all
conditions to the consummation of the Merger, the Merger is expected to become
effective during the first quarter of 1998. The "Effective Time" will occur
when a certificate of merger reflecting the Merger is duly filed with the
Secretary of State of Delaware. Either Premiere or Xpedite may terminate the
Merger Agreement if the Merger has not been consummated by April 30, 1998,
provided that the date may be extended until May 30, 1998 if this Joint Proxy
Statement/Prospectus has been mailed to the stockholders of both Xpedite and
Premiere before April 30, 1998, and provided further that the right to so
terminate the Merger Agreement will not be available to any party whose failure
to fulfill any obligation under the Merger Agreement resulted in the failure of
the Merger to occur on or before such date. See "The Merger--Effective Time,"
"--Conditions to Consummation," "--Regulatory Approvals," and "--Termination
and Possible Exchange Ratio Increase."
 
  Distribution of the Merger Consideration. As soon as practicable after the
Effective Time, Premiere shall cause a bank or trust company selected jointly
by Premiere and Xpedite (the "Exchange Agent") to mail to each holder of record
of Xpedite Common Stock, a form of letter of transmittal (a "Letter of
Transmittal"). The Letter of Transmittal will specify that risk of loss and
title to certificates of Xpedite Common Stock surrendered
 
                                       4
<PAGE>
 
by Xpedite stockholders in the Merger (the "Xpedite Certificates") will pass
upon delivery thereof to the Exchange Agent, and will contain instructions for
use in effecting the surrender of the Xpedite Certificates. The Letter of
Transmittal must be properly completed, signed and submitted to the Exchange
Agent and accompanied by the Xpedite Certificates for Xpedite stockholders to
receive the Merger Consideration.
 
  HOLDERS OF XPEDITE COMMON STOCK SHOULD NOT SEND IN THEIR CERTIFICATES
REPRESENTING SHARES OF XPEDITE COMMON STOCK UNTIL THEY RECEIVE THE LETTER OF
TRANSMITTAL, WHICH WILL BE SENT TO FORMER HOLDERS OF XPEDITE COMMON STOCK AS
SOON AS PRACTICABLE FOLLOWING THE EFFECTIVE TIME.
   
  Opinions of Financial Advisors. On November 13, 1997, the Xpedite Board of
Directors received an opinion of Merrill Lynch that, as of such date, the
Merger Consideration was fair, from a financial point of view, to the holders
of Xpedite Common Stock. For purposes of rendering the opinion, Merrill Lynch
assumed that Xpedite would not consummate the Merger under circumstances where
the Threshold Price Termination Right (as defined in "Summary--The Merger;
Termination and Possible Exchange Ratio Increase") is exercisable and therefore
such opinion would be inapplicable under such circumstances. See "The Merger--
Termination and Possible Exchange Ratio Increase." The full text of Merrill
Lynch's written opinion delivered to the Xpedite Board of Directors, which sets
forth the assumptions made, matters considered and qualifications and
limitations on the review undertaken by Merrill Lynch, is attached as Annex B
hereto. Holders of Xpedite Common Stock are urged to and should read such
opinion in its entirety. For additional information regarding the opinion of
Merrill Lynch and a discussion of the qualifications of Merrill Lynch, its
selection as independent financial advisor to the Xpedite Board of Directors,
and certain relationships between Merrill Lynch and Xpedite, see "The Merger--
Opinions of Financial Advisors; Xpedite." See "The Merger--Termination and
Possible Exchange Ratio Increase."     
 
  On November 12, 1997, Prudential Securities delivered its written opinion to
the Board of Directors of Premiere to the effect that as of such date the
consideration to be paid by Premiere pursuant to the Merger was fair, from a
financial point of view, to Premiere. The full text of such opinion, dated
November 12, 1997, which sets forth the assumptions made, matters considered
and limitations on the review undertaken in connection with such opinion, is
attached hereto as Annex C to this Joint Proxy Statement/Prospectus and is
incorporated herein by reference. Holders of shares of Premiere Common Stock
and Premiere Preferred Stock are urged to, and should, read such opinion in its
entirety. For additional information regarding the opinion of Prudential
Securities and a discussion of the qualifications of Prudential Securities, its
selection as independent financial advisor to the Premiere Board of Directors,
and certain relationships between Prudential Securities, and Premiere and
Xpedite, see "The Merger--Opinions of Financial Advisors; Premiere."
   
  Certain Federal Income Tax Consequences. The Merger is intended to be a tax-
free reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code"). Assuming the Merger qualifies as
a tax-free reorganization, no gain or loss will be recognized for federal
income tax purposes by Xpedite stockholders as a result of the Merger, except
that gain or loss will be recognized with respect to cash received in lieu of
fractional shares. If for any reason the Merger does not so qualify, exchanging
stockholders will recognize gain or loss on the exchange of their stock. A
condition to consummation of the Merger is the receipt by each of Premiere and
Xpedite of an opinion from Alston & Bird LLP ("Alston & Bird"), counsel to
Premiere, that, among other things, the Merger will qualify as a tax-free
reorganization. A discussion of matters regarding qualification for tax-free
reorganization treatment is set forth below. See "The Merger--Certain Federal
Income Tax Consequences."     
 
  Upon the sale or exchange of Premiere Common Stock, a holder of such stock
generally will recognize capital gain or loss equal to the difference between
the amount of cash and the fair market value of any property received upon the
sale or exchange and such holder's adjusted tax basis in the Premiere Common
Stock. Under recently enacted legislation, capital gains recognized by certain
non-corporate holders of Premiere Common Stock generally will be subject to a
maximum federal income tax rate of 20% if the shares sold or exchanged are held
for more than 18 months, and to a maximum federal income tax rate of 28% if
such shares are held for
 
                                       5
<PAGE>
 
more than one year but are not held for more than 18 months. Tax consequences
to dealers in Premiere Common Stock, non-United States holders of Premiere
Common Stock or others who have a special tax status (including, without
limitation, financial institutions, insurance companies and tax-exempt
entities) or to persons who received their shares through the exercise of
employee stock options or otherwise as compensation may be different and such
persons should consult their tax advisors as to the tax consequences of a sale
or exchange of Premiere Common Stock.
 
  BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE
PARTICULAR CIRCUMSTANCES OF EACH XPEDITE STOCKHOLDER AND BECAUSE VARIOUS
FACTUAL MATTERS DISCUSSED BELOW MUST BE RESOLVED FAVORABLY FOR TAX FREE
REORGANIZATION TREATMENT TO APPLY, EACH HOLDER OF XPEDITE COMMON STOCK IS URGED
TO CONSULT SUCH HOLDER'S OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE APPLICATION AND EFFECT
OF FOREIGN, STATE AND LOCAL INCOME AND OTHER TAX LAWS).
 
  Interests of Certain Persons in the Merger. Certain members of Xpedite's
management and the Board of Directors of Xpedite have interests in the Merger
in addition to their interests as stockholders of Xpedite generally. These
include, among other things, provisions in the Merger Agreement relating to the
agreement by Premiere to maintain existing officer and director indemnification
and insurance benefits and the granting by Premiere of options and stay bonuses
to certain key employees of Xpedite. See "The Merger--Management and Operations
After the Merger" and "--Interests of Certain Persons in the Merger."
   
  Conditions to Consummation. Consummation of the Merger is subject to various
conditions, including, among other matters: (i) adoption of the Merger
Agreement by the requisite vote of the holders of Xpedite Common Stock; (ii)
approval of the issuance of shares of Premiere Common Stock pursuant to the
Merger Agreement by the requisite vote of the holders of Premiere Common Stock
and Premiere Preferred Stock, voting as a single class; (iii) consummation of
the XSL Acquisition (which occurred on December 17, 1997); (iv) satisfaction of
applicable antitrust requirements; (v) receipt by Premiere and Xpedite of an
opinion of Alston & Bird dated as of the Effective Time relating to certain tax
matters; and (vi) satisfaction of certain other usual conditions. See "The
Merger--Conditions to Consummation" and "--Regulatory Approvals."     
 
  Conduct of Business Pending the Merger. Xpedite generally has agreed in the
Merger Agreement that, pending consummation of the Merger or termination of the
Merger Agreement, unless the prior consent of Premiere is obtained or except as
required by the XSL Purchase Agreement, Xpedite will operate its business only
in the ordinary course consistent with past practice, and will use all
reasonable efforts to preserve its business organizations, keep available the
services of its officers, employees and consultants, and preserve present
relationships with customers, suppliers, and others with which Xpedite has
significant business relationships. In addition, Xpedite has agreed not to take
certain actions relating to the operation of its business, except as
contemplated by the Merger Agreement and the XSL Purchase Agreement, pending
consummation of the Merger or the termination of the Merger Agreement, without
the prior approval of Premiere.
 
  Premiere generally has agreed in the Merger Agreement that, pending
consummation of the Merger or termination of the Merger Agreement, unless the
prior consent of Xpedite is obtained, it will conduct its business, in a manner
designed in its reasonable judgment to enhance the long-term value of the
Premiere Common Stock and the business prospects of Premiere, and will use its
reasonable efforts to preserve its core businesses and goodwill with their
respective present officers, employees, consultants, customers, suppliers and
other persons with which Premiere has significant business relations. The
foregoing, however, does not prevent Premiere from acquiring any assets or
businesses if such action is, in Premiere's judgment, desirable in the conduct
of Premiere's businesses. In addition, Premiere has agreed not to take certain
actions relating to the operation of its business, except as contemplated by
the Merger Agreement, pending consummation of the Merger or the termination of
the Merger Agreement, without the prior approval of Xpedite.
   
  Furthermore, Xpedite has agreed not to authorize, and to use its reasonable
efforts to cause its officers, directors, employees, or agents not to, directly
or indirectly: (i) solicit, initiate, or encourage any inquiries or     
 
                                       6
<PAGE>
 
proposals regarding any merger, reorganization, consolidation, business
combination, recapitalization, liquidation, dissolution, sale of any
significant portion of assets, sale of shares of capital stock or similar
transaction involving Xpedite other than the Merger ("Acquisition Proposal");
(ii) engage in negotiations or discussions concerning, or provide any nonpublic
information or assistance to any person in connection with any Acquisition
Proposal; or (iii) agree to, approve or recommend any Acquisition Proposal.
Xpedite's Board of Directors, however, is entitled to consider, negotiate,
discuss, approve, and recommend to Xpedite's stockholders a bona fide
Acquisition Proposal not solicited in violation of the Merger Agreement,
provided that the Xpedite Board of Directors determines in good faith that it
is required to do so in order to discharge properly its fiduciary duties to
Xpedite's stockholders. Xpedite must immediately notify Premiere after receipt
of any Acquisition Proposal or any modification of or amendment to any
Acquisition Proposal, or any request for nonpublic information relating to
Xpedite or its subsidiaries or access to the properties, books or records of
Xpedite or its subsidiaries by any person or entity that informs Xpedite that
it is considering making, or has made, an Acquisition Proposal, and Xpedite
must keep Premiere informed, on a reasonably current basis, as to the status
and details of any bona fide consideration, negotiations or discussions
concerning an Acquisition Proposal.
 
  See "The Merger--Conduct of Business Pending the Merger."
 
  Termination and Possible Exchange Ratio Increase. Either Premiere or Xpedite
may terminate the Merger Agreement, before or after the approval by
stockholders of Premiere or Xpedite, if: (i) the Boards of Directors of
Premiere and Xpedite mutually agree; (ii) the Merger has not been consummated
by April 30, 1998, provided that the date will be extended until May 30, 1998
if this Joint Proxy Statement/Prospectus has been mailed to the stockholders of
both Xpedite and Premiere before April 30, 1998, and provided further that the
right to so terminate the Merger Agreement will not be available to any party
whose failure to fulfill any obligation under the Merger Agreement resulted in
the failure of the Merger to occur on or before such date; (iii) any court of
competent jurisdiction or other governmental, regulatory or administrative
agency or commission has issued an order or taken any other action having the
effect of permanently restraining, enjoining or otherwise prohibiting the
Merger and such order or action has become final and nonappealable, provided
that the right to terminate the Merger Agreement shall not be available to any
party who materially contributed to the issuance of any such order or the
taking of such action; (iv) the Board of Directors of Xpedite recommends an
Alternative Transaction (as defined in "The Merger--Termination and Possible
Exchange Ratio Increase") to the Xpedite stockholders; or (v) a tender offer or
exchange offer for 15% or more of the outstanding shares of Xpedite Common
Stock is commenced (other than by Premiere or an affiliate of Premiere) and the
Board of Directors of Xpedite recommends that the Xpedite stockholders tender
their shares in such tender or exchange offer; provided that Xpedite shall not
be entitled to exercise any termination rights under clauses (iv) or (v) unless
(x) any action of the Board of Directors of Xpedite referred to in such clauses
is required to be taken by the Xpedite Board of Directors in order to properly
discharge its fiduciary duties to the Xpedite stockholders and (y) Xpedite has
complied with its obligations not to solicit Acquisition Proposals.
   
  The Merger Agreement further provides that it may be terminated by Premiere,
before or after the approval by stockholders of Premiere or Xpedite: (i) in the
event the Board of Directors of Xpedite withdraws, modifies or changes its
approval or recommendation of the Merger Agreement or the Merger in a manner
adverse to Premiere; or (ii) in the event of a material breach by Xpedite of
any representation, warranty, covenant or agreement contained in the Merger
Agreement which has not been cured within 30 days following receipt by Xpedite
of written notice of such breach, in any case such that Xpedite's conditions to
consummation of the Merger set forth in the Merger Agreement would be incapable
of being satisfied by April 30, 1998; provided that Premiere may not terminate
the Merger Agreement if Premiere is itself in material breach of any of its
representations, warranties, covenants or agreements set forth in the Merger
Agreement, such that Xpedite's conditions to consummation of the Merger set
forth in the Merger Agreement would be incapable of being satisfied by April
30, 1998.     
   
  Xpedite may terminate the Merger Agreement before or after the approval by
stockholders of Premiere or Xpedite: (i) if the Board of Directors of Premiere
shall have recommended to the stockholders of Premiere (x)     
 
                                       7
<PAGE>
 
   
any acquisition or proposed acquisition of Premiere by a merger, consolidation
or other business combination (including any so-called "merger of equals" and
whether or not Premiere is the entity surviving any such merger or business
combination) in which the consideration to be received by Premiere stockholders
in such business combination shall be other than cash, (y) any liquidation or
dissolution of Premiere, or (z) any transaction or series of transactions in
which Third Parties (as defined in "The Merger--Termination and Possible
Exchange Ratio Increase") would acquire substantially all of the consolidated
assets of Premiere; (ii) if a tender offer or exchange offer for 50% or more of
the outstanding shares of Premiere Common Stock is commenced and the Board of
Directors of Premiere recommends that the stockholders of Premiere tender their
shares in such tender or exchange offer; (iii) if the Board of Directors of
Premiere shall withdraw, modify or change its approval or recommendation of the
Merger Agreement or the Merger in a manner adverse to Xpedite; (iv) in the
event of a material breach by Premiere of any representation, warranty,
covenant or agreement contained in the Merger Agreement which has not been
cured within 30 days following receipt by Premiere of written notice of such
breach, in any case such that Premiere's conditions to consummation of the
Merger set forth in the Merger Agreement would be incapable of being satisfied
by April 30, 1998, provided that Xpedite may not terminate the Merger Agreement
if Xpedite is itself in material breach of any of its representations,
warranties, covenants or agreements set forth in the Merger Agreement, such
that Premiere's conditions to consummation of the Merger set forth in the
Merger Agreement would be incapable of being satisfied by April 30, 1998; or
(v) as set forth in the following paragraph.     
   
  Finally, Xpedite may terminate the Merger Agreement (the "Threshold Price
Termination Right") if the Board of Directors of Xpedite so determines by a
vote of a majority of the members of its entire Board, at any time during the
three-business-day period commencing on the day that the Average Closing Price
is determined, if the actual Average Closing Price shall be less than $24.00
(the "Threshold Price"); subject, however, to the following: (x) if Xpedite
elects to exercise its termination right pursuant to this clause, it shall give
prompt written notice thereof to Premiere (provided that such notice of
election to terminate may be withdrawn at any time within the three-business-
day period referenced in clause (y) below); (y) during the three-business-day
period commencing with its receipt of such notice, Premiere shall have the
option, in its sole discretion, to elect to increase the Exchange Ratio to
equal the quotient obtained by dividing (I) the product of the Threshold Price
and the Exchange Ratio (as then in effect) by (II) the Average Closing Price;
and (z) if Premiere makes an election contemplated by clause (y) within such
three-business-day period, it shall give prompt written notice to Xpedite of
such election and the revised Exchange Ratio, whereupon no termination shall be
deemed to have occurred and the Merger Agreement shall remain in effect in
accordance with its terms (except as the Exchange Ratio shall have been so
modified), and any references in the Merger Agreement to "Exchange Ratio" shall
thereafter be deemed to refer to the Exchange Ratio as adjusted.     
       
       
          
  It is not possible to know if the Average Closing Price will be less than the
Threshold Price until the day immediately preceding the date of the Xpedite
Special Meeting and the Premiere Special Meeting. Since the date of the Merger
Agreement, the market price of Premiere Common Stock has been subject to
significant fluctuation, with the high and low closing price therefor ranging
from $28 11/16 to $21 7/8. On January 27, 1998, the closing price of Premiere
Common Stock was $24 1/4. The fairness opinions received by each of Xpedite and
Premiere are based on the conditions in effect at the time the parties executed
the Merger Agreement. In addition, the Merrill Lynch Opinion (as defined in
"The Merger--Opinions of Financial Advisors") expressly assumes that Xpedite
would not consummate the Merger under circumstances where the Threshold Price
Termination Right is exercisable. Accordingly, the Merrill Lynch Opinion does
not address the circumstances that might arise if the Xpedite Board has decided
to consummate the Merger in a case where the Threshold Price Termination Right
is exercisable but the Premiere Board has chosen not to increase the Exchange
Ratio. Likewise, the Prudential Securities Opinion (as defined in "The Merger--
Opinions of Financial Advisors") does not address the circumstance where the
Average Closing Price is below the Threshold Price and the Premiere Board
chooses to increase the Exchange Ratio. See "The Merger--Opinions of Financial
Advisors." While the Xpedite Board currently intends to exercise its right to
terminate the Merger Agreement if the Average Closing Price is less     
 
                                       8
<PAGE>
 
   
than the Threshold Price, it has not made a final determination and it is not
obligated to exercise such right and the final decision as to whether it would
exercise such right in such event, or to withdraw its notice of termination as
provided in the Merger Agreement, would be made at the time the termination
right becomes exercisable or in the event that the Premiere Board declines to
increase the Exchange Ratio, as applicable. While the Premiere Board does not
currently intend to increase the Exchange Ratio in the event Xpedite elects to
exercise its termination right, its final decision whether to increase the
Exchange Ratio would be made if and when Xpedite were to exercise its
termination right. In considering whether to exercise their respective rights
in each situation, each of the Xpedite and the Premiere Boards would,
consistent with its fiduciary duties, take into account all relevant facts and
circumstances that exist at such time and would consult with its respective
financial advisors and legal counsel. APPROVAL OF THE MERGER AGREEMENT BY THE
STOCKHOLDERS OF XPEDITE AT THE XPEDITE SPECIAL MEETING AND APPROVAL OF THE
ISSUANCE OF SHARES OF PREMIERE COMMON STOCK PURSUANT TO THE MERGER AGREEMENT BY
THE STOCKHOLDERS OF PREMIERE AT THE PREMIERE SPECIAL MEETING WILL CONFER ON THE
XPEDITE BOARD AND THE PREMIERE BOARD, RESPECTIVELY, THE POWER, CONSISTENT WITH
THE FIDUCIARY DUTIES OF SUCH BOARDS, TO ELECT TO CONSUMMATE THE MERGER IF THE
AVERAGE CLOSING PRICE IS LESS THAN THE THRESHOLD PRICE (IN THE CASE OF THE
XPEDITE BOARD) OR TO ELECT TO INCREASE THE EXCHANGE RATIO IN THE EVENT XPEDITE
ELECTS TO EXERCISE ITS TERMINATION RIGHT (IN THE CASE OF THE PREMIERE BOARD)
WITHOUT ANY FURTHER ACTION BY, OR RESOLICITATION OF, THE STOCKHOLDERS OF
XPEDITE AND PREMIERE, AS THE CASE MAY BE.     
 
  See "The Merger--Termination and Possible Exchange Ratio Increase."
   
  Expenses and Termination Fees. The Merger Agreement provides that, except for
the termination fees described below, each party is responsible for its own
expenses incident to preparing for, entering into, and carrying out the Merger
Agreement and the consummation of the transactions contemplated thereby. In the
event that the Merger Agreement is terminated by either party for any reason,
Xpedite shall pay to Premiere an amount equal to $9,500,000 (the "Premiere
Fee") plus all documented fees and expenses incurred by Premiere and its
subsidiaries in connection with or related to the authorization, preparation,
regulation, execution and performance of the Merger Agreement and the
transactions contemplated thereby (including, without limitation, all fees and
expenses of counsel, accountants, investment bankers, experts, consultants,
banks and other financial institutions) (the "Premiere Expenses") up to a
maximum of $1,000,000 in the aggregate; provided that: (i) Xpedite shall not be
obligated to pay the Premiere Fee or any Premiere Expenses if the Merger
Agreement is terminated under certain specified conditions; and (ii) Xpedite
shall be obligated to reimburse Premiere for the amount of Premiere Expenses
incurred by it up to a maximum of $1,000,000, but shall not be obligated to pay
the Premiere Fee, if the Merger Agreement is terminated under certain other
specified conditions. Notwithstanding the above, Premiere shall pay to Xpedite
an amount equal to $9,500,000 plus all documented fees and expenses incurred by
Xpedite and its subsidiaries in connection with or related to the
authorization, preparation, regulation, execution and performance of the Merger
Agreement and the Agreement and Plan of Merger dated as of August 8, 1997
between Xpedite and Xpedite Acquisition Corp., an entity formed by UBS Capital
LLC ("UBS") and Fenway Partners, Inc. ("Fenway") (the "Prior Merger Agreement")
and the transactions contemplated thereby (including, without limitation, all
fees and expenses of counsel, accountants, investment bankers, experts,
consultants, banks and other financial institutions) up to a maximum of
$1,000,000 in the aggregate in the event the Merger Agreement is terminated
under certain specified conditions. See "The Merger--Expenses and Termination
Fees."     
   
  Amendment and Waiver. To the extent permitted by law, Premiere and Xpedite
may amend the Merger Agreement by written agreement at any time without the
approval of the stockholders of Xpedite; provided that after the approval of
the Merger Agreement by Xpedite's stockholders, no amendment may change the
consideration to be received by Xpedite stockholders or the rights of the
Xpedite stockholders under the Merger Agreement without the requisite approval
of such stockholders. To the extent required by the Nasdaq rules, any     
 
                                       9
<PAGE>
 
such amendment which increases the consideration payable to the Xpedite
stockholders will be submitted to the Premiere stockholders for their approval.
 
  Prior to or at the Effective Time, either Xpedite or Premiere may also (i)
extend the time for the performance of any of the obligations or other acts of
the other party under the Merger Agreement, (ii) waive any inaccuracies in the
representations and warranties contained in the Merger Agreement or any
document delivered pursuant thereto, or (iii) except to the extent prohibited
by law, waive compliance with any of the agreements or conditions contained in
the Merger Agreement.
 
  Accounting Treatment. The Merger is anticipated to be accounted for on a
pooling-of-interests accounting basis. See "The Merger--Accounting Treatment."
 
  Resales of Premiere Common Stock. The shares of Premiere Common Stock issued
in connection with the Merger will be freely transferable under the Securities
Act, except for shares issued to any stockholder who may be deemed to be an
"affiliate" (generally including, without limitation, directors, certain
executive officers, and beneficial owners of 10% or more of any class of
capital stock) of Xpedite for purposes of Rule 145 under the Securities Act as
of the date of the Xpedite Special Meeting. Such affiliates may not sell their
shares of Premiere Common Stock acquired in connection with the Merger except
pursuant to an effective registration statement under the Securities Act or any
applicable exemption from the registration requirements of the Securities Act.
This Joint Proxy Statement/Prospectus does not cover resales of Premiere Common
Stock received by any person who may be deemed to be an affiliate of Xpedite.
See "The Merger--Resales of Premiere Common Stock."
 
  Registration Rights. As provided in the Merger Agreement, each person (a
"Large Stockholder") who is precluded by Rule 145 under the Securities Act from
selling or disposing of all of their shares of Premiere Common Stock received
in the Merger (the "Registrable Securities") within one calendar quarter is
entitled to certain registration rights. These registration rights are subject
to certain limitations and restrictions, including the right of the
underwriters of an underwritten offering to limit the numbers of shares offered
in such registration if such underwriter determines that the number of shares
requested to be registered cannot be underwritten. See "The Merger--
Registration Rights."
   
  Stockholder Agreements. As provided in the Merger Agreement, Premiere and
each of the directors and certain of the executive officers of Xpedite and
certain holders of 5% or more of the outstanding shares of Xpedite Common Stock
have entered into Stockholder Agreements that contain, among other things, an
agreement to vote the shares of Xpedite Common Stock owned by them on the
Xpedite Record Date in favor of the Merger. The Stockholder Agreements
terminate upon the earlier of the termination of the Merger Agreement or the
Effective Time. See "The Merger--Stockholder Agreements."     
 
  No Dissenters' Rights. Holders of Xpedite Common Stock will not have any
appraisal rights under the Delaware General Corporation Law ("Delaware GCL") in
connection with the Merger Agreement and the consummation of the Merger. See
"General Information--Xpedite Special Meeting," "General Information--Premiere
Special Meeting," "The Merger--Interests of Certain Persons in the Merger,"
"Stock Ownership of Certain Beneficial Owners and Management of Xpedite" and
"Stock Ownership of Certain Beneficial Owners and Management of Premiere."
 
  Differences in Stockholder Rights. The rights of Xpedite stockholders
currently are determined by reference to the Delaware GCL, Xpedite's Amended
and Restated Certificate of Incorporation ("Xpedite's Certificate") and
Xpedite's Bylaws. Following the Effective Time, Xpedite stockholders will
become stockholders of Premiere, and their rights as stockholders will be
determined by the Georgia Business Corporation Code ("Georgia BCC"), Premiere's
Articles of Incorporation, as amended ("Premiere's Articles"), and Premiere's
Amended and Restated Bylaws ("Premiere's Bylaws"). For a description of the
material differences in the rights of Xpedite and Premiere stockholders, see
"Certain Differences in the Rights of Premiere and Xpedite Stockholders."

STOCK PLAN AMENDMENT
 
  The Premiere Board of Directors has adopted an amendment to Premiere's
Second Amended and Restated 1995 Stock Plan (the "Stock Plan"), the purpose of
which is to increase the number of shares of Premiere Common Stock reserved
for issuance from 4,000,000 to 8,000,000. This proposal is separate from and
in addition to the amendments previously adopted by the holders of Premiere
Common Stock at the 1997 Annual Meeting.
 
  The purpose of the Stock Plan is to advance the interests of Premiere, its
subsidiaries and shareholders by affording certain employees and directors of,
and key consultants and advisors to, Premiere and its subsidiaries, an
opportunity to acquire or increase their proprietary interests in Premiere.
Particularly, the Plan promotes the growth and profitability of Premiere by
providing such persons opportunities to acquire options, stock appreciation
rights and restricted stock grants relating to the Premiere Common Stock
(collectively, the "Awards"). Premiere believes that the grant of the Awards
encourages such persons' continued association with, or service to, Premiere.
Premiere intends to issue options to purchase up to 2,000,000 shares of
Premiere Common Stock to the current employees of Xpedite and to individuals
that Premiere recruits to join the Xpedite management team (the "Key Xpedite
Employee Options"). The Key Xpedite Employee Options will be granted at the
fair market value of Premiere Common Stock on the date of grant and generally
will vest ratably over a period of four years. See "The Merger--Interests of
Certain Persons in the Merger."
   
  The Premiere Board of Directors believes that the Stock Plan Amendment is
needed to provide Premiere with greater flexibility to attract and retain
highly qualified employees, directors, key consultants and advisors in the
future. As of December 31, 1997, there were approximately 659,418 shares of
Premiere Common Stock available for Awards. The Board believes that Premiere
will need additional shares of Premiere Common Stock for future issuances.
    
  The affirmative vote of a majority of the shares of Premiere Common Stock
and Premiere Preferred Stock, voting together as a single class, present at
the Premiere Special Meeting is required to approve the Stock Plan Amendment.
 
  See "Stock Plan Amendment."

  On January 27, 1998, the closing price of Premiere Common Stock was $24 1/4.
See "The Merger--Termination and Possible Exchange Ratio Increase."     
 
  The Merger Agreement provides for the filing of a listing application with
Nasdaq covering the shares of Premiere Common Stock issuable pursuant to the
Merger Agreement. It is a condition to consummation of the Merger that such
shares of Premiere Common Stock be authorized for listing on Nasdaq, upon
official notice of issuance. See "The Merger--Conditions to Consummation."
 
  Neither Xpedite nor Premiere has ever paid cash dividends on its common
stock, and the current policy of Premiere's Board of Directors is to retain any
available earnings for use in the operation and expansion of Premiere's
business. Therefore, the payment of cash dividends on the Premiere Common Stock
is unlikely in the foreseeable future. Any future determination to pay cash
dividends will be at the discretion of the Premiere Board of Directors and will
depend upon Premiere's earnings, capital requirements, financial condition and
any other factors deemed relevant by the Premiere Board of Directors.
 
COMPARISON OF CERTAIN UNAUDITED PER SHARE DATA
 
  The following summary presents certain selected comparative unaudited per
share data for Premiere and Xpedite on a historical basis, and on a pro forma
combined and equivalent pro forma combined basis assuming the Merger had been
effective during the periods presented using an assumed 1.25 Exchange Ratio for
the Merger and assuming the XSL Acquisition had been effective as of January 1,
1996. The Merger is reflected under the pooling-of-interests method of
accounting and the XSL Acquisition is reflected under the purchase method of
accounting and pro forma data is derived accordingly. The information shown
below should be read in conjunction with the historical financial statements of
Premiere, Xpedite and XSL, including the respective notes thereto, incorporated
by reference herein, and with the unaudited pro forma financial information
including the notes thereto, appearing elsewhere or incorporated by reference
herein. See "Available Information," "Incorporation of Certain Information by
Reference," "The Merger--Accounting Treatment," and "Pro Forma Condensed

(2) Excluding charges for purchased research and development, accrued
    settlement costs and restructuring and other special charges incurred by
    Premiere in the amounts of approximately $0, $0 and $6.7 million,
    respectively, in 1994, and approximately $0, $2.5 and $0 million,
    respectively, in 1995, and approximately $11.0, $1.3 and $0 million,
    respectively, in 1996, operating income (loss), net income (loss) and pro
    forma net income (loss) per share (on a fully diluted basis when
    applicable) would have been approximately $(6.5) million, $(11.4) million
    and $(0.87) respectively, for 1994 and approximately $9.5 million, $5.7
    million and $0.22, respectively, for 1995 and approximately $19.2 million,
    $11.0 million and $0.37, respectively, for 1996. Excluding charges for
    restructuring and other special charges attributable to the Voice-Tel
    Acquisitions and the acquisition of VoiceCom and accrued litigation and
    settlement costs of $73.6 million and $1.5 million, respectively, operating
    income, net income and pro forma net income per share (on a fully diluted
    basis when applicable) would have been approximately $31.2 million, $19.0
    million and $0.55, respectively, for the nine months ended September 30,
    1997.     
(3) Pro forma net income (loss) per share is computed using the weighted
    average number of shares of common stock and dilutive common stock
    equivalents from convertible preferred stock (using the if-converted
    method) and from stock options (using the modified treasury stock method).
    Further, for the years ended December 31, 1992, 1993, and 1994 and the nine
    months ended September 30, 1997, net income (loss) per share was not
    calculated under the modified treasury stock method as the results were
    antidilutive. Accordingly, basic net income (loss) per share calculations
    were used for the years ended December 31, 1992, 1993 and 1994 and the nine
    months ended September 30, 1997.
(4) Fully diluted net income (loss) per share is not presented where the effect
    is antidilutive.

(2) Supplementary pro forma net income per share assuming the conversion of
    Premiere preferred stock and the retirement of notes payable for the year
    ended December 31, 1995 are not presented because the effect of the pro
    forma adjustments is immaterial.     
   
(3) Pro forma net income (loss) per share is computed using the weighted
    average number of shares of common stock and dilutive common stock
    equivalents from convertible preferred stock (using the if-converted
    method) and from stock options (using the modified treasury stock method).
    Fully diluted data is not presented as the effect is anti-dilutive or
    immaterial for all periods presented. Further, for the years ended
    December 31, 1994, 1995 and 1996 and the nine months ended September 30,
    1997, net income per share was not calculated under the modified treasury
    stock method as the results were antidilutive. Accordingly, basic net
    income (loss) per share calculations were used for the years ended
    December 31, 1994, 1995 and 1996 and the nine months ended September 30,
    1997.

                                 RISK FACTORS
 
  Xpedite shareholders should carefully consider the risk factors set forth
below, as well as the other information contained in this Joint Proxy
Statement/Prospectus, in evaluating an exchange of Xpedite Common Stock for
Premiere Common Stock. This Joint Proxy Statement/Prospectus and the documents
incorporated herein contain certain forward-looking statements which are
inherently uncertain. Premiere's actual results could differ materially from
those anticipated in these forward-looking statements as a result of certain
factors, including those set forth below and elsewhere in this Joint Proxy
Statement/Prospectus. See "Forward-Looking Statements."
 
ABILITY TO MANAGE GROWTH; ACQUISITION RISKS
   
  Premiere continually evaluates acquisition opportunities and, as a result,
frequently engages in acquisition discussions, conducts due diligence
activities in connection with possible acquisitions, and, where appropriate,
engages in acquisition negotiations. Premiere has experienced substantial
growth in revenue and personnel in recent years, particularly in 1997. A
substantial portion of such growth has been accomplished through acquisitions,
including the Voice-Tel Acquisitions and the acquisition of VoiceCom.
Premiere's growth has placed significant demands on all aspects of Premiere's
business, including its administrative, technical and financial personnel and
systems. Additional expansion by Premiere, including the Merger, may further
strain Premiere's management, financial and other resources. There can be no
assurance that Premiere's systems, procedures, controls and existing space are
or will be adequate to support expansion of Premiere's operations. Premiere's
future operating results will substantially depend on the ability of its
officers and key employees to manage changing business conditions and to
implement and improve its administrative, technical and financial control and
reporting systems. If Premiere is unable to respond to and manage changing
business conditions, then the quality of Premiere's services, its ability to
retain key personnel and its results of operations could be materially
adversely affected. At certain stages of growth in network usage, Premiere
will be required to add capacity to its computer telephony platform and its
digital central office switches and will need to continually add capacity to
its private frame relay network, thus requiring Premiere continuously to
attempt to predict growth in its network usage and add capacity accordingly.
Difficulties in managing continued growth, including difficulties in
predicting the growth in network usage, could have a material adverse effect
on Premiere's business, financial condition and results of operations.     
   
  Acquisitions, including the Merger, also involve numerous additional risks,
including difficulties in the assimilation of the operations, services,
products and personnel of the acquired company, the diversion of Premiere's
management's attention from other business concerns, entry into markets in
which Premiere has little or no direct prior experience and the potential loss
of key employees of the acquired company. Premiere is unable to predict
whether or when any prospective acquisition candidate will become available or
the likelihood that any acquisition will be completed. There are, at present,
no understandings, agreements or arrangements concerning the issuance of
additional shares of Premiere Common Stock in connection with possible
acquisitions, except for the shares to be issued pursuant to the Merger
Agreement.     
   
  Future acquisitions by Premiere may result in potentially dilutive issuances
of equity securities, the incurrence of additional debt, the assumption of
known and unknown liabilities, the write-off of software development costs and
the amortization of expenses related to goodwill and other intangible assets,
all of which could have a material adverse effect on Premiere's business,
financial condition and results of operations. For example, the Voice-Tel
Entities and VoiceCom established reserves for certain potential tax
liabilities that Premiere's management believes to be adequate based on
certain assumptions which Premiere's management believes are reasonable. If,
however, such assumptions prove to be incorrect and the potential liabilities
ultimately exceed established reserves, Premiere's business, financial
condition and results of operations could be materially adversely affected.
Premiere has recorded approximately $14.8 million of goodwill and other
intangible assets in connection with the Voice-Tel Acquisitions. Premiere is
amortizing the goodwill on a straight-line basis over 40 years, and Premiere
believes the useful life of the Voice-Tel Entities to be at least 40 years. If
the amortization period is accelerated due to a reevaluation of the useful
life of the Voice-Tel Entities or otherwise, amortization expense may
initially increase on a quarterly basis or require a write-down of the
goodwill. An increase in the rate of amortization of goodwill or future write-
downs and restructuring charges could have a material adverse effect on
Premiere's business, financial condition and results of operations.     
 
                                      19
<PAGE>
 
   
  Premiere has taken, and in the future may take, charges in connection with
acquisitions. During the second quarter of 1997, Premiere took a pre-tax
charge of approximately $45.4 million in connection with the Voice-Tel
Acquisitions and during the third quarter of 1997, Premiere took a pre-tax
charge of approximately $28.2 million in connection with the acquisition of
VoiceCom. Premiere may take additional charges in connection with future
acquisitions including, but not limited to, the Merger. There can be no
assurance that the costs and expenses incurred will not exceed the estimates
upon which such charges are based.     
          
  In June 1997, Premiere completed the Voice-Tel Acquisitions. Prior to the
Voice-Tel Acquisitions, the Voice-Tel Entities operated approximately 210 POPs
in five countries. VTE operated as a franchisor, and each of the approximately
100 Franchisees was independently owned and operated. Premiere is in the
process of consolidating these separate businesses by attempting to eliminate
duplicative and unnecessary costs and to operate them under common management.
Potential challenges to the successful consolidation of the Voice-Tel Entities
include, but are not limited to: (i) centralization and consolidation of
financial, operational and administrative functions; (ii) consolidation of the
service centers, network and work force; (iii) elimination of unnecessary
costs; and (iv) realization of economies of scale. Premiere is in the process
of integrating Voice-Tel's service offerings, operations and systems with
those of Premiere, and therefore, the Voice-Tel integration plans may
materially change in the future. Challenges to the successful integration of
the Voice-Tel Entities include, but are not limited to: (i) localization of
Premiere products; (ii) integration of the Premiere platform with the Voice-
Tel network; (iii) cross-selling of products and services to the customer base
of Voice-Tel and Premiere; (iv) integration of new personnel; and (v)
compliance with regulatory requirements.     
 
  Because of the size and fragmented nature of the facilities and businesses
of the Voice-Tel Entities and the technical complexity of integrating
Premiere's products with those of Voice-Tel, the integration process is
particularly complex and will place significant demands on Premiere's
management, engineering, financial and other resources. There can be no
assurance that the Voice-Tel Entities will be successfully consolidated or
integrated with Premiere's operations on schedule or at all, that the Voice-
Tel Acquisitions will result in sufficient net sales or earnings to justify
Premiere's investment therein or the expenses related thereto, or that
operational synergies will develop. The successful consolidation of the Voice-
Tel Entities and their integration into Premiere's operations are critical to
Premiere's future performance, especially because the combined revenues for
the Voice-Tel Entities approximated 45.0% and 42.0% of Premiere's revenues in
fiscal year 1996 and the nine months ended September 30, 1997, respectively.
Failure to successfully consolidate and integrate the Voice-Tel Entities or to
achieve operating synergies would have a material adverse effect on Premiere's
business, financial condition and results of operations.
 
THE EFFECT OF STOCK PRICE FLUCTUATIONS ON THE CONSIDERATION TO BE RECEIVED BY
THE HOLDERS OF XPEDITE COMMON STOCK IN THE MERGER
 
  The price of Premiere Common Stock at the Effective Time may vary
significantly from the closing price as of the date as of which the Merger
Agreement was executed, the date hereof, or the date on which Xpedite
stockholders vote on the Merger and the transactions contemplated thereby. The
market price of Premiere Common Stock has historically been subject to
significant fluctuation. See "Summary--Market Prices and Dividends." These
variances may be due to a number of factors, including, without limitation,
actual or anticipated quarterly fluctuations in financial results, changes in
earnings estimates by securities analysts and announcements of material events
by Premiere, its major strategic partners or licensees or its competitors,
market assessments of the likelihood that the Merger will be consummated and
the timing thereof, the effect of any conditions or restrictions imposed on or
proposed with respect to the combined companies by regulatory agencies in
connection with or following consummation of the Merger, perceptions about
market conditions in the telecommunications industry and the effect of general
economic conditions, many of which are unrelated to Premiere's operating
performance.
 
  The Exchange Ratio is based, in part, on the market price of the Premiere
Common Stock. The Merger Agreement places a limitation on the Average Closing
Price by deeming the Average Closing Price to be $27.20 if the actual Average
Closing Price falls below the Minimum Average Closing Price, and $39.20 if the
actual Average Closing Price is greater than the Maximum Average Closing
Price. Accordingly, the dollar value of the Premiere Common Stock to be
received by the holders of Xpedite Common Stock to be issued in the Merger
 
                                      20
<PAGE>
 
   
will not be determined until the day immediately preceding the Xpedite Special
Meeting. If the Average Closing Price of the Premiere Common Stock is below
$27.20, or above $39.20, the dollar value of the Premiere Common Stock to be
received by the holders of Xpedite Common Stock in the Merger may be
substantially more or less than the value of the Premiere Common Stock as of
the date of execution of the Merger Agreement, the date hereof, the date of
the Xpedite Special Meeting, the date of receipt of shares of Premiere Common
Stock by Xpedite stockholders, or the date on which such shares are eventually
sold. The Exchange Ratio is subject to possible increase under certain
circumstances if the actual Average Closing Price would be less than $24.00.
Since the date of the Merger Agreement, the market price of Premiere Common
Stock has been subject to significant fluctuation, with the high and low
closing price therefor ranging from $28 11/16 to $21 7/8. On January 27, 1998,
the closing price of Premiere Common Stock was $24 1/4. See "The Merger--
Termination and Possible Exchange Ratio Increase."     
 
  Shareholders should also note that, due to possible delays in receiving
regulatory approvals or in satisfying other conditions to consummation of the
Merger, there may be a significant delay between the date of the Xpedite
Special Meeting and the date of consummation of the Merger. Accordingly, the
market value of shares of Premiere Common Stock that holders of Xpedite Common
Stock will receive upon consummation of the Merger may vary significantly from
the market value of the shares of Premiere Common Stock that holders of
Xpedite Common Stock would receive if the Merger were consummated on the date
of this Joint Proxy Statement/Prospectus or the date of the Xpedite Special
Meeting.
 
DEPENDENCE ON LICENSING AND STRATEGIC RELATIONSHIPS
 
  Premiere has licensing relationships with companies that have chosen to
outsource part or all of their communications card services to Premiere.
License fees accounted for approximately 7.0% of Premiere's revenues in 1996
and 11.6% of Premiere's revenues during the nine months ended September 30,
1997. One licensee, Communications Network Corporation ("CNC"), accounted for
approximately 19.6% of Premiere's 1996 license fees and approximately 1.4% of
Premiere's total 1996 revenues. On August 6, 1996, CNC was placed into
bankruptcy under Chapter 11 of the United States Bankruptcy Code. CNC owed
Premiere approximately $627,000 as of December 31, 1996. However, CNC's
transmission provider, WorldCom Network Services, Inc., d/b/a WilTel, is also
obligated to pay this amount to Premiere. In addition, WorldCom, Inc.
("WorldCom") accounted for approximately 43.5% of Premiere's 1996 license fees
and approximately 3.0% of Premiere's total 1996 revenues, and approximately
69.5% of Premiere's license fees and 8.1% of Premiere's total revenues for the
nine months ended September 30, 1997. Premiere intends to increase its number
of licensees and its licensee transaction volume in the future. Premiere's
success depends in part upon the ultimate success or failure of its licensees.
The telecommunications industry is intensely competitive and rapidly
consolidating. The majority of companies that have chosen to outsource
communications card services to Premiere are small or medium-sized
telecommunications companies that may be unable to withstand the intense
competition in the telecommunications industry. Licensees that ceased doing
business with Premiere due to financial difficulties contributed in the
aggregate approximately $2.9 million of Premiere's 1996 revenues. Although
Premiere was able to add new licensees in 1996 and the first three quarters of
1997, there can be no assurance that the failure of one or more of Premiere's
licensees to develop and sustain a market for Premiere's services, or
termination of one or more of Premiere's licensing relationships, will not
have a material adverse effect on Premiere's business, financial condition and
results of operations.
 
UNCERTAINTY OF STRATEGIC RELATIONSHIPS
 
  A principal element of Premiere's strategy is the creation and maintenance
of strategic relationships that will enable Premiere to offer its services to
a larger customer base than Premiere could otherwise reach through its direct
marketing efforts. Premiere has experienced growth in its existing strategic
relationships during 1996 and 1997 and has entered into or initiated new
strategic relationships with several companies, including WorldCom, American
Express Travel Related Services, Inc. ("American Express") and CompuServe
Incorporated ("CompuServe"). Although Premiere intends to continue to expand
its direct marketing channels, Premiere believes that strategic partner
relationships may offer a potentially more effective and efficient marketing
channel. Consequently, Premiere's success depends in part on the ultimate
success of these relationships and on the ability of these strategic partners
to market Premiere's services effectively. Failure of one or more of
Premiere's strategic partners to successfully develop and sustain a market for
Premiere's services, or the termination of one or more of Premiere's
relationships with a strategic partner, could have a material
 
                                      21
<PAGE>
 
adverse effect on Premiere's overall performance. The telecommunications
industry is experiencing rapid consolidation. Recently WorldCom, which is a
strategic partner of Premiere, entered into an agreement to acquire MCI, which
competes with Premiere with respect to certain services. Consolidation in the
communications industry, including consolidations involving Premiere's
customers and strategic partners, could have a material adverse effect on
Premiere's business, financial condition and results of operations.
 
  In November 1996, Premiere entered into a strategic alliance agreement with
WorldCom, the fourth largest long distance carrier in the United States,
whereby WorldCom is required, among other things, to provide Premiere with the
right of first opportunity to provide certain enhanced computer telephony
services for a period of at least 25 years. In connection with this agreement,
Premiere issued to WorldCom 2,050,000 shares of Premiere Common Stock valued
at approximately $25.2 million (based on an independent appraisal) and paid
WorldCom $4.7 million in cash. Premiere recorded the value of this agreement
as an intangible asset. While Premiere believes that the intangible asset will
be recovered over the life of the agreement, this recoverability is dependent
upon the success of the strategic relationship. Premiere will continually
evaluate the realizability of the intangible asset recorded, and there can be
no assurance that future evaluations will not require a write-down of this
asset.
 
  Although Premiere views its strategic relationships as a key factor in its
overall business strategy and in the development and commercialization of its
services, there can be no assurance that its strategic partners view their
relationships with Premiere as significant for their own businesses or that
they will not reassess their commitment to Premiere in the future. Premiere's
arrangements with its strategic partners do not always establish minimum
performance requirements for Premiere's strategic partners, but instead rely
on the voluntary efforts of these partners in pursuing joint goals. Certain of
these arrangements prevent Premiere from entering into strategic relationships
with other companies in the same industry as Premiere's strategic partners,
either for specified periods of time or while the arrangements remain in
force. In addition, even when Premiere is without contractual restriction, it
may be restrained by business considerations from pursuing alternative
arrangements. The ability of Premiere's strategic partners to incorporate
Premiere's services into successful commercial ventures will require Premiere,
among other things, to continue to successfully enhance its existing services
and develop new services. Premiere's inability to meet the requirements of its
strategic partners or to comply with the terms of its strategic partner
arrangements could result in its strategic partners failing to market
Premiere's services, seeking alternative providers of communications and
information services or canceling their contracts with Premiere, any of which
could have a material adverse impact on Premiere's business, financial
condition and results of operations.
 
RELIANCE ON AMWAY AND CERTAIN OTHER RELATIONSHIPS
   
  Historically, the Voice-Tel Entities have relied on sales through Amway
Corporation ("Amway") for a substantial portion of their revenue. Such sales
accounted for approximately 27.5%, 23.7% and 21.9% of Premiere's revenue for
1995, 1996 and the nine months ended September 30, 1997, respectively. Amway's
relationship with VTE commenced in 1990 when VTE began managing the voice
messaging operations previously conducted by Amway's subsidiary, Amvox, Inc.
("Amvox"). VTE subsequently acquired and franchised the former Amvox service
centers from Amway in exchange for an equity interest in VTE. Amway later
invested in the development of the private frame relay digital messaging
network through VTN. As a result of these transactions, Amway also became the
single largest equity holder in VTE and VTN. VTE and Amway have entered into a
service and reseller agreement (the "Amway Agreement") providing, among other
things, for the sale by VTE of voice messaging and network transmission
services on an exclusive basis to Amway in the United States, Canada, New
Zealand and Australia for resale by Amway to its independent distributors
under the "Amvox" trade name. The Amway Agreement does not bind the Amway
distributors, who are free to acquire messaging services from alternative
vendors. The Amway Agreement may be canceled by either party upon 180 days
prior written notice or upon shorter notice in the event of a breach. The
Amway Agreement does not prohibit VTE from continuing to provide voice
messaging and network transmission services to Amway's distributors following
termination of the Amway Agreement. However, in the event that Amway
recommended a voice messaging and network transmission services provider other
than Premiere, there can be no assurance that Amway's distributors would not
follow such recommendation. Amway has certain registration rights with respect
to the Premiere Common Stock that it acquired in the Voice-Tel Acquisitions
(see "Risk Factors-- Registration Rights"). Amway demanded registration of its
shares in accordance with its rights and sold a significant portion of its
Premiere Common Stock on December 30, 1997. Such sale by Amway decreased     
 
                                      22
<PAGE>
 
Amway's interest in Premiere and may increase the possibility that Amway will
recommend a voice messaging and network transmission services provider other
than Premiere. There can be no assurance that Premiere's relationship with
Amway and the Amway distributors will continue at historical levels or at all,
nor can there be any assurance of long-term price protection for services
provided to Amway. Loss or diminution in the Amway relationship, or a decrease
in average sales price without an offsetting increase in volume, could have a
material adverse effect on Premiere's business, financial condition and
results of operations.
   
  In September 1997, Premiere entered into an agreement with DigiTEC 2000,
Inc. ("Digitec") pursuant to which Digitec will act as a distributor to market
and sell prepaid telephone cards. Under the terms of such agreement, Digitec
agreed, starting January 1, 1998, to sell cards with a retail value of at
least $4 million each month. In the event that Digitec has not sold all such
cards by August 31, 1998, Digitec will be obligated to pay Premiere an amount
equal to the retail value of the unsold cards less commissions that would have
been payable on such cards. No assurance can be given that Digitec will be
able to sell the amount of cards that it is obligated to under the terms of
such agreement or, in the event that Digitec is unable to do so, that Digitec
will have the financial resources available to it to make the payment required
on August 31, 1998 under such agreement.     
 
TECHNOLOGICAL CHANGE; RISK OF OBSOLESCENCE; DEPENDENCE ON NEW SERVICES
   
  The market for Premiere's and Xpedite's services is characterized by rapid
technological change, frequent new product introductions and evolving industry
standards. Premiere's future success will depend in significant part on its
ability to anticipate industry standards, continue to apply advances in
technologies, enhance its current services, develop and introduce new services
in a timely fashion, enhance its software and its computer telephony platform
and compete successfully with products and services based on evolving or new
technologies. Premiere expects new products and services, and enhancements to
existing products and services, to be developed and introduced which will
compete with the services offered by Premiere. Among the new and evolving
technologies with which Premiere expects to compete are notebook computers
equipped with sound cards, fax modems and cellular modems, portable Internet
appliances which would allow connection to the Internet over wireless networks
and personal digital assistants with enhanced communications features. In
addition, aspects of Premiere's Orchestrate product line, which Premiere
intends to begin marketing during the first quarter of 1998, is expected to
compete within markets where larger companies are working to provide a unified
messaging solution. Premiere is also aware that products currently exist which
provide text-to-voice e-mail conversion and "call connect/call screening"
services.     
 
  Such technological advances may result in the availability of new services,
products or methods of electronic document delivery that could compete with
the electronic document distribution services currently provided by Premiere
and Xpedite or decrease the cost of existing products or services which could
enable Premiere's and/or Xpedite's established or potential customers to meet
their own needs for electronic document distribution services more cost
efficiently than through the use of the combined company's services. In
addition, Premiere may experience difficulty integrating incompatible systems
of acquired businesses into its network. There can be no assurance that
Premiere will not be materially adversely affected in the event of such
technological change or difficulty, or that changes in technology will not
enable additional companies to offer services which could replace, or be more
cost-effective than, some or all of the services offered now by Premiere or
Xpedite or in the future by the combined company.
   
  The Voice-Tel Acquisitions constitute a significant investment by Premiere
in a private frame relay network architecture. Alternative architectures
currently exist, and technological advances may result in the development of
additional network architectures. There can be no assurance that the
telecommunications industry will not standardize on a protocol other than
frame relay or that Premiere's frame relay architecture will not become
obsolete. Such events would require Premiere to invest significant capital in
upgrading or replacing its private frame relay network and could have a
material adverse effect on Premiere's business, financial condition and
results of operations.     
   
  Premiere must continually introduce new products in response to evolving
industry standards and customer demands for enhancements to Premiere's
existing products. One such new product is Orchestrate, which is operational
and has been available in limited release. Premiere intends to begin marketing
Orchestrate to customers through certain of Premiere's strategic partners such
as CompuServe Incorporated ("CompuServe")     
 
                                      23
<PAGE>
 
   
and USA.NET, Inc. ("USA.NET") in the first quarter of 1998. Premiere
anticipates commencing direct marketing of the Orchestrate product through
print advertising and other channels during the second quarter of 1998.
Premiere believes that its competitors have not yet developed a publicly
available network-based product which incorporates all of the functionalities
of Orchestrate, although Premiere's competitors have developed products which
Premiere believes offer some, but not all, of the bundled services offered
through Orchestrate. There can be no assurance that: (i) Premiere will be
successful in developing and marketing service enhancements or new services
that respond to these or other technological changes or evolving industry
standards; (ii) Premiere will not experience difficulties that could delay or
prevent the successful development, introduction and marketing of its
services, including Orchestrate; or (iii) its new services and the
enhancements thereto, including Orchestrate, will adequately meet the
requirements of the marketplace and achieve market acceptance. Delays in the
introduction of new services, the inability of Premiere to develop such new
services or the failure of such services to achieve market acceptance could
have a material adverse effect on Premiere's business, financial condition and
results of operations.     
 
UNCERTAINTY OF MARKET ACCEPTANCE OF COMPUTER TELEPHONY
   
  Premiere's future success depends upon the market acceptance of its existing
and future computer telephony product lines and services. Computer telephony
integrates the functionality of telephones and computers and thus represents a
departure from standards for information and telecommunications services.
Market acceptance of computer telephony products and services generally
requires that individuals and enterprises accept a new way of exchanging
information. Premiere believes that broad market acceptance of its computer
telephony product lines and services will depend on several factors, including
ease of use, price, reliability, access and quality of service, system
security, product functionality and the effectiveness of strategic marketing
and distribution relationships. There can be no assurance that Premiere's
computer telephony products and services will achieve broad market acceptance
or that such market acceptance will occur at the rate which Premiere currently
anticipates. A decline in the demand for, or the failure to achieve broad
market acceptance of, Premiere's computer telephony product lines and services
would have a material adverse effect on Premiere's business, financial
condition and results of operations.     
 
RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION
   
  A key component of the Premiere strategy is its planned expansion into
international markets. In 1996, Premiere opened a POP site in London, England
which is currently being upgraded to a full switching facility and computer
telephony platform. In addition, Premiere intends to pursue long term
strategic relationships with European partners. Premiere also intends to
establish high speed client/server networks of personal computers (called
"Telnodes") and PCs utilizing Premiere's proprietary software (called "Network
Managers") in Canada, New Zealand and potentially other countries in 1998.
Premiere currently has voice messaging service centers in Canada, Australia,
New Zealand and Puerto Rico. If international revenues are not adequate to
offset the expense of establishing and maintaining these international
operations, Premiere's business, financial condition and results of operations
could be materially adversely affected. To date, Premiere has only limited
experience in marketing and distributing its services internationally. There
can be no assurance that Premiere will be able to successfully establish the
proposed international Telnodes and Network Managers or to market, sell and
deliver its services in international markets. In addition to the uncertainty
as to Premiere's ability to expand its international presence, there are
certain difficulties and risks inherent in doing business on an international
level, such as burdensome regulatory requirements and unexpected changes in
these requirements, export restrictions, export controls relating to
technology, tariffs and other trade barriers, difficulties in staffing and
managing international operations, longer payment cycles, problems in
collecting accounts receivable, political instability, fluctuations in
currency exchange rates, seasonal reductions in business activity during the
summer months in Europe and certain other parts of the world and potentially
adverse tax consequences. Premiere denominates foreign transactions in foreign
currency and does not engage in hedging transactions. Premiere has not
experienced any material losses from fluctuations in currency exchange rates,
but there can be no assurance that Premiere will not incur material losses due
to currency exchange rate fluctuations in the future.     
   
  A significant portion of Xpedite's business is conducted outside the United
States, and a significant portion of its revenues and expenses are derived in
foreign currencies. Accordingly, Xpedite's results of operations may     
 
                                      24
<PAGE>
 
   
be materially affected by fluctuations in foreign currencies. Many aspects of
Xpedite's international operations and business expansion plans are subject to
foreign government regulations, currency fluctuations, political uncertainties
and differences in business practices. There can be no assurance that foreign
governments will not adopt regulations or take other actions that would have a
direct or indirect adverse impact on the business or market opportunities of
Xpedite within such governments' countries, including increased tariffs.
Furthermore, there can be no assurance that the political, cultural and
economic climate outside the United States will be favorable to Xpedite's
operations and growth strategy. As a result of the XSL Acquisition and the
acquisition of Xpedite Germany, a higher proportion of Xpedite's business is
now conducted outside the United States and, accordingly, Xpedite may be
subject, to a greater degree, to the foregoing risks.     
 
RISKS ASSOCIATED WITH EXPANSION OF ENHANCED FAX SERVICES
   
  Premiere intends to accelerate growth of enhanced fax and message delivery
services throughout the world by expansion of Xpedite's proprietary private
world-wide document distribution network (the "Xpedite Network"), the
integration of the Xpedite Network with Premiere's private frame relay network
and computer telephony platform and the acquisition of entities engaged in the
business of Enhanced Fax Services. There can be no assurance that Premiere
will be able to expand its ability to provide services at a rate or in a
manner satisfactory to meet the demands of existing or future customers,
including, but not limited to, increasing the capacity of the Xpedite Network
to process increasing amounts of document traffic, integrating and increasing
the capability of the Xpedite Network to perform tasks required by Premiere's
customers, or identifying and establishing alliances with new partners in
order to enable Premiere to expand its network in new geographic regions. Such
inability may adversely affect customer relationships and perceptions of
Premiere in the markets in which it provides services, which could have a
material adverse effect on Premiere's business, financial condition and
results of operations. In addition, such growth will involve substantial
investments of capital, management and other resources. There can be no
assurance that Premiere will generate sufficient cash for future growth of the
Enhanced Fax Services business through earnings or external financings, or
that such external financings will be available on terms acceptable to
Premiere or that Premiere will be able to employ any such resources in a
manner that will result in accelerated growth.     
 
DEPENDENCE ON KEY MANAGEMENT AND PERSONNEL
   
  Premiere's success is largely dependent upon its executive officers and
other key personnel, the loss of one or more of whom could have a material
adverse effect on Premiere. Premiere believes that its continued success will
depend to a significant extent upon the efforts and abilities of Boland T.
Jones, Chairman and President, and certain other key executives. Mr. Jones has
entered into an employment agreement with Premiere which expires in December
1999, and Premiere maintains key man life insurance on Mr. Jones in the amount
of $3.0 million. D. Gregory Smith, a co-founder of Premiere, recently resigned
as director, Executive Vice President and Assistant Secretary of Premiere and
as a director and officer of Premiere Communications, Inc. ("PCI") and certain
other subsidiaries of Premiere, and Leonard A. DeNittis recently resigned as
the Vice President of Engineering and Operations of PCI.     
 
  Premiere also believes that to be successful it must hire and retain highly
qualified engineering and product development personnel. Competition in the
recruitment of highly qualified personnel in the information and
telecommunications services industry is intense. The inability of Premiere to
locate, hire and retain such personnel may have a material adverse effect on
Premiere. No assurance can be given that Premiere will be able to retain its
key employees or that it will be able to attract qualified personnel in the
future.
 
LIMITED PROTECTION OF PROPRIETARY RIGHTS AND TECHNOLOGY
   
  Premiere relies primarily on a combination of intellectual property laws and
contractual provisions to protect its proprietary rights and technology. These
laws and contractual provisions provide only limited protection of Premiere's
proprietary rights and technology. Premiere's proprietary rights and
technology include confidential information and trade secrets which Premiere
attempts to protect through confidentiality and nondisclosure provisions in
its licensing, services, resellers and distribution agreements. Premiere
typically attempts to protect its confidential information and trade secrets
through these contractual provisions for the term of the applicable     
 
                                      25
<PAGE>
 
   
agreement and, to the extent permitted by applicable law, for some negotiated
period following termination of the agreement, typically one to two years at a
minimum. In addition, Premiere has three patent applications pending and nine
trademark or service mark registrations pending. Premiere has two registered
service marks. Voice-Tel has been issued two U.S. patents and has one U.S.
patent application pending. Voice-Tel also has five registered U.S. trademarks
or service marks and approximately 40 foreign trademark or service mark
registrations or pending applications. VoiceCom has two registered U.S.
trademarks and one registered foreign trademark. Despite Premiere's efforts to
protect its proprietary rights and technology through intellectual property
laws and contractual provisions, unauthorized parties may attempt to copy
aspects of Premiere's software or services or to obtain and use information
that Premiere regards as proprietary. Although Premiere is not aware of any
current or previous infringement of its proprietary rights and technology,
there can be no assurance that Premiere's means of protecting its proprietary
rights and technology will be adequate or that Premiere's competitors will not
independently develop similar technology. In addition, the laws of some
foreign countries do not protect Premiere's proprietary rights to as great an
extent as the laws of the U.S.     
 
DEPENDENCE ON SWITCHING FACILITIES AND COMPUTER TELEPHONY PLATFORMS; DAMAGE,
FAILURE AND DOWNTIME
   
  Premiere currently maintains switching facilities and computer telephony
platforms in Atlanta, Georgia, Dallas, Texas, and London, England. Premiere's
network service operations are dependent upon its ability to protect the
equipment and data at its switching facilities against damage that may be
caused by fire, power loss, technical failures, unauthorized intrusion,
natural disasters, sabotage and other similar events. Premiere has taken
precautions to protect itself and its subscribers from events that could
interrupt delivery of Premiere's services. These precautions include physical
security systems, uninterruptible power supplies, on-site power generators,
upgraded backup hardware and fire protection systems. Premiere's network is
further designed such that the data on each network server is duplicated on a
separate network server. Notwithstanding such precautions, and although
Premiere has not experienced any significant downtime of its network in the
last three years due to technical failures, natural disasters or similar
events, there can be no assurance that a fire, act of sabotage, technical
failure, natural disaster or a similar event would not cause the failure of a
network server and its backup server, other portions of Premiere's network or
one of the switching facilities as a whole, thereby resulting in an
interruption of Premiere's services. Such an interruption could have a
material adverse effect on Premiere's business, financial condition and
results of operations. Although Premiere maintains business interruption
insurance providing for aggregate coverage of approximately $10.8 million per
policy year, there can be no assurance that Premiere will be able to maintain
its business interruption insurance, that such insurance will continue to be
available at reasonable prices or that such insurance will be sufficient to
compensate Premiere for losses it experiences due to Premiere's inability to
provide services to its subscribers.     
 
RISK OF SOFTWARE FAILURES OR ERRORS
   
  The software developed and utilized by Premiere in providing its services,
including the Orchestrate software, may contain undetected errors. Although
Premiere generally engages in extensive testing of its software prior to
introducing the software onto its network, there can be no assurance that
errors will not be found in the software after the software goes into use. Any
such error may result in partial or total failure of Premiere's network,
additional and unexpected expenses to fund further product development or to
add programming personnel to complete a development project, and loss of
revenue because of the inability of subscribers to use Premiere's network or
the cancellation by subscribers of their service with Premiere, any of which
could have a material adverse effect on Premiere. Premiere maintains
technology errors and omissions insurance coverage of $10.0 million per policy
aggregate. However, there can be no assurance that Premiere will be able to
maintain its technology errors and omissions insurance, that such insurance
will continue to be available at reasonable prices or will be sufficient to
compensate Premiere for losses it experiences due to Premiere's inability to
provide services to its subscribers.     
 
DEPENDENCE UPON TELECOMMUNICATION PROVIDERS; NO GUARANTEED SUPPLY
 
  Premiere does not own a transmission network and, accordingly, depends on
WorldCom, LCI International Telecom Corp. ("LCI"), MCI Communications Corp.
("MCI"), Sprint Corp. ("Sprint") and other facilities-based and non-facilities
based carriers for transmission of its subscribers' long distance calls. These
long distance
 
                                      26
<PAGE>
 
   
telecommunications services generally are procured pursuant to supply
agreements for terms of three to five years, subject to earlier termination in
certain events. Certain of these agreements provide for minimum purchase
requirements. Further, Premiere is dependent upon local exchange carriers
("LECs") for call origination and termination. If there is an outage affecting
one of Premiere's terminating carriers, Premiere's platform automatically
switches calls to another terminating carrier if capacity is available.
Premiere has not experienced significant losses in the past due to
interruptions of service at terminating carriers, but no assurance can be made
in this regard in the future. Premiere's ability to maintain and expand its
business depends, in part, on its ability to continue to obtain
telecommunication services on favorable terms from long distance carriers and
the cooperation of both interexchange and LECs in originating and terminating
service for its subscribers in a timely manner. The partial or total loss of
the ability to receive or terminate calls would result in a loss of revenues
by Premiere and could lead to a loss of subscribers, which could have a
material adverse effect on Premiere.     
   
  Premiere leases capacity on the WorldCom backbone to provide connectivity
and data transmission within Premiere's private frame relay network. The lease
agreement expires in September 2000. Premiere's hub equipment is collocated at
various WorldCom sites pursuant to co-location agreements that are terminable
by either party upon 30 days written notice. Premiere's ability to maintain
network connectivity is dependent upon its access to transmission facilities
provided by WorldCom or an alternative provider. Premiere has no assurance
that it will be able to continue such relationship with WorldCom beyond the
terms of its current agreements with WorldCom or that it will be able to find
an alternative provider on terms as favorable as those offered by WorldCom or
on any other terms. If Premiere were required to relocate its hub equipment or
change its network transmission provider, it could experience shutdowns in its
service and increase costs which could have a material adverse effect on its
customer relationships and customer retention and, therefore, its business,
financial condition and results of operations.     
 
RELIANCE ON SUPPLIERS OF VOICE MESSAGING EQUIPMENT
 
  Premiere does not manufacture voice messaging equipment used at its voice
messaging service centers, and such equipment is currently available from a
limited number of sources. Although Premiere has not historically experienced
any significant difficulty in obtaining equipment required for its operations
and believes that viable alternative suppliers exist, no assurance can be
given that shortages will not arise in the future or that alternative
suppliers will be available. The inability of Premiere to obtain this
equipment could result in delays or reduced delivery of messages which would
materially and adversely affect Premiere's business, financial condition and
results of operations.
 
RISKS OF INFRINGEMENT CLAIMS
   
  Many patents, copyrights and trademarks have been issued in the general
areas of information and telecommunications services and computer telephony.
Premiere believes that in the ordinary course of its business third parties
will claim that Premiere's current or future products or services infringe the
patent, copyright or trademark rights of such third parties. No assurance can
be given that actions or claims alleging patent, copyright or trademark
infringement will not be brought against Premiere with respect to current or
future products or services, or that, if such actions or claims are brought,
Premiere will ultimately prevail. Any such claiming parties may have
significantly greater resources than Premiere to pursue litigation of such
claims. Any such claims, whether with or without merit, could be time
consuming, result in costly litigation, cause delays in introducing new or
improved products and services, require Premiere to enter into royalty or
licensing agreements, or cause Premiere to discontinue use of the challenged
technology, trade name or service mark at potentially significant expense to
Premiere associated with the marketing of a new name or the development or
purchase of replacement technology, all of which could have a material adverse
effect on Premiere's business, financial condition and results of operations.
See "Incorporation of Certain Information by Reference" and "Available
Information."     
   
  In February 1997, Premiere entered into a long-term nonexclusive license
agreement with AudioFAX IP LLC ("AudioFAX") settling a patent infringement
suit filed by AudioFAX in June 1996. In the third quarter of 1996, Premiere
took a one-time charge for the estimated legal fees and other costs that
Premiere expected to incur to resolve this matter. In September 1997, VoiceCom
also entered into a long-term nonexclusive license agreement with AudioFAX.
    
                                      27
<PAGE>
 
   
  In July 1996, Xpedite received a letter from counsel for AudioFAX, which
informed Xpedite that AudioFAX is the owner of certain U.S. and Canadian
patents relevant to the fax processing business entitled "Facsimile
Telecommunications Systems and Method" (the "Patents"), and inquired as to
Xpedite's interest in obtaining a license to use the Patents. Xpedite has
reviewed the Patents, obtained certain legal opinions with respect to the
Patents and concluded that it is not necessary to obtain a license to the
Patents. AudioFAX has continued to pursue the licensing of the Patents by
Xpedite. Xpedite's management cannot predict the outcome of this matter,
including but not limited to whether or not AudioFAX will commence a lawsuit
against Xpedite in order to induce Xpedite to enter into a license to use the
Patents. There can be no assurance that the resolution of such matter will not
have a material adverse effect on Xpedite's or Premiere's business, financial
condition and results of operations.     
 
POTENTIAL ADVERSE IMPACT OF PENDING LITIGATION
   
  In the ordinary course of its business, Premiere is subject to claims and
litigation from third parties alleging that Premiere's products and services
infringe the patents, trademarks and copyrights of such third parties.
Premiere has several litigation matters pending, not involving infringing
claims, which Premiere is defending vigorously. Due to the inherent
uncertainties of the litigation process and the judicial system, Premiere is
unable to predict the outcome of such litigation matters. If the outcome of
one or more of such matters is adverse to Premiere, it could have a material
adverse effect on Premiere's business, financial condition and results of
operations. See "Incorporation of Certain Information by Reference" and
"Available Information."     
 
RISK OF LOSS FROM RETURNED TRANSACTIONS; FRAUD; BAD DEBT; THEFT OF SERVICES
   
  Premiere uses two principal financial payment clearance systems: the Federal
Reserve's Automated Clearing House for electronic fund transfers; and the
national credit card systems for electronic credit card settlement. In its use
of these established payment clearance systems, Premiere generally bears
credit risks similar to those normally assumed by other users of these systems
arising from returned transactions caused by insufficient funds, stop payment
orders, closed accounts, frozen accounts, unauthorized use, disputes, theft or
fraud. From time to time, persons have gained unauthorized access to
Premiere's network and obtained services without rendering payment to Premiere
by unlawfully using the access numbers and Personal Identification Numbers
("PINs") of authorized users. In addition, in connection with Premiere's
wholesale prepaid telephone card relationships, Premiere has experienced
unauthorized activation of prepaid telephone cards. No assurance can be given
that losses due to unauthorized use of access numbers and PINs, unauthorized
activation of prepaid calling cards or activation of prepaid calling cards in
excess of the prepaid amount, or theft of prepaid calling cards will not be
material. Premiere attempts to manage these risks through its internal
controls and proprietary billing system. Premiere's computer telephony
platform is designed to prohibit a single access number and PIN from
establishing multiple simultaneous connections to the platform, and Premiere
establishes preset spending limits for each subscriber. Premiere also
maintains reserves for such risks. Past experience in estimating and
establishing reserves and Premiere's historical losses are not necessarily
accurate indicators of Premiere's future losses or the adequacy of the
reserves established by Premiere in the future. Although Premiere believes
that its risk management and bad debt reserve practices are adequate, there
can be no assurance that Premiere's risk management practices, including its
internal controls, or reserves will be sufficient to protect Premiere from
unauthorized or returned transactions or thefts of services which could have a
material adverse effect on Premiere's business, financial condition and
results of operations.     
 
REGULATION
 
  Various regulatory factors affect Premiere's financial performance and its
ability to compete. Premiere's operating subsidiaries that provide regulated
long distance telecommunications services ("Operating Subsidiaries") are
subject to regulation by the Federal Communications Commission ("FCC") and by
various state public service and public utility commissions ("PUCs"), and are
otherwise affected by regulatory decisions, trends and policies made by these
agencies. FCC rules currently require interexchange carriers to permit resale
of their transmission services. FCC rules also require LECs to provide all
interexchange carriers with equal access to local exchange facilities for
purposes of origination and termination of long distance calls.
 
                                      28
<PAGE>
 
   
If either or both of these requirements were eliminated, Premiere could be
adversely affected. Moreover, the underlying carriers that provide services to
the Operating Subsidiaries or that originate or terminate the Operating
Subsidiaries' traffic may increase rates or experience disruptions in service
due to factors outside Premiere's control, which could cause the Operating
Subsidiaries to experience increases in rates for telecommunications services
or disruptions in transmitting their subscribers' long distance calls.     
 
  PCI, one of the Operating Subsidiaries, has made the requisite filings with
the FCC to provide interstate and international long distance services.
VoiceCom Systems, Inc. ("VCOM"), another Operating Subsidiary, is in the
process of making the requisite filings with the FCC to provide interstate and
international long distance services. There can be no assurance that the FCC
will approve VCOM's filings. Failure by VCOM to comply with FCC requirements
in connection with its provision of interstate and international long distance
services could have a material adverse effect on Premiere's or on VCOM's
business, financial condition and results of operation.
 
  In order to provide intrastate long distance service, the Operating
Subsidiaries generally are required to obtain certification from state PUCs,
to register with such state PUCs or to be found exempt from registration by
such state PUCs. Each of PCI and VCOM has either filed the applications
necessary to provide intrastate long distance telecommunications services
throughout the United States or is in the process of filing such applications.
To date, PCI is authorized to provide long distance telecommunications
services in 46 states and in the District of Columbia and is seeking
authorization to provide long distance telecommunications services in four
states. With the exception of three states, Colorado, Michigan and Arizona, in
which PCI's applications to provide operator service (i.e., "0+") are pending,
PCI is authorized to provide operator service in each state where PCI provides
long distance telecommunications service. VCOM, on the other hand, is
authorized to provide long distance telecommunications services in 13 states
and in the District of Columbia and is in the process of filing applications
for certificates to provide long distance telecommunications services in 37
states. The Operating Subsidiaries' facilities do not prevent subscribers from
using the facilities to make long distance calls in any state, including
states in which the Operating Subsidiaries currently are not authorized to
provide intrastate telecommunications services and operator services. There
can be no assurance that the Operating Subsidiaries' provision of long
distance telecommunications and operator services in states where the
Operating Subsidiaries are not authorized to provide such services will not
have a material adverse effect on Premiere's or on the Operating Subsidiaries'
business, financial condition and results of operations.
   
  The Telecommuncations Act of 1996 (the "1996 Act") is intended to increase
competition in the long distance and local telecommunications markets. The
1996 Act opens competition in the local services market and, at the same time,
contains provisions intended to protect consumers and businesses from unfair
competition by incumbent LECs, including the regional bell operating companies
("RBOCs"). The 1996 Act allows RBOCs to provide long distance service outside
of their local service territories but bars them from immediately offering in-
region long distance services between Local Access and Transport Areas
("LATAs") until certain conditions are satisfied. An RBOC must apply to the
FCC to provide in-region interLATA long distance services and must satisfy a
set of pro-competitive criteria intended to ensure that RBOCs open their own
local markets to competition before the FCC will approve such application.
Recently a Texas federal district court held this ban to be unconstitutional.
The court's decision is subject to further review. As a result of the 1996 Act
and the court's decision, if upheld, Premiere may experience increased
competition from others, including the RBOCs. In addition, the Operating
Subsidiaries may be subject to additional regulatory requirements and fees,
including universal service assessments and pay phone compensation surcharges
resulting from the implementation of the 1996 Act.     
 
  In conducting its business, Premiere is subject to various laws and
regulations relating to commercial transactions generally, such as the Uniform
Commercial Code and is also subject to the electronic funds transfer rules
embodied in Regulation E promulgated by the Board of Governors of the Federal
Reserve System (the "Federal Reserve"). Congress has held hearings regarding,
and various agencies are considering, whether to regulate providers of
services and transactions in the electronic commerce market. For example, the
Federal Reserve recently completed a study, directed by Congress, regarding
the propriety of applying Regulation E to stored value cards. The Department
of Treasury recently promulgated proposed rules applying record keeping,
 
                                      29
<PAGE>
 
reporting and other requirements to a wide variety of entities involved in
electronic commerce. It is possible that Congress, the states or various
government agencies could impose new or additional requirements on the
electronic commerce market or entities operating therein. If enacted, such
laws, rules and regulations could be imposed on Premiere's business and
industry and could have a material adverse effect on Premiere's business,
financial condition and results of operations. Premiere's proposed
international activities also will be subject to regulation by various
international authorities and the inherent risk of unexpected changes in such
regulation.
 
COMPETITION
 
  The market for Premiere's services is intensely competitive, rapidly
evolving and subject to rapid technological change. Premiere expects
competition to increase in the future. Many of Premiere's current and
potential competitors have longer operating histories, greater name
recognition, larger customer bases and substantially greater financial,
personnel, marketing, engineering, technical and other resources than
Premiere. Premiere believes that existing competitors are likely to expand
their service offerings and that new competitors are likely to enter the
personal communications market and to attempt to integrate such services,
resulting in greater competition for Premiere. Such competition could have a
material adverse effect on Premiere's business, financial condition and
results of operations.
   
  Premiere attempts to differentiate itself from its competitors by offering
an integrated suite of enhanced personal communications services. Other
providers currently offer each of the individual services and certain
combinations of the services offered by Premiere. Premiere's worldwide mobile
communications services and features compete with services provided by
companies such as AT&T Corp. ("AT&T"), MCI and Sprint as well as smaller
interexchange long distance providers. Premiere's voice mail services,
including those acquired in the Voice-Tel Acquisitions and the acquisition of
VoiceCom, compete with voice mail services provided by AT&T, certain RBOCs and
other service bureaus as well as by equipment manufacturers, such as Octel
Communications Corporation ("Octel"), Northern Telecom, Inc. ("Northern
Telecom"), Siemens Business Communications Systems, Inc. ("Siemens"),
Centigram Communications Corporation ("Centigram"), Boston Technology, Inc.
("Boston Technology") and Digital Sound Corporation ("Digital Sound").
Premiere's enhanced travel, concierge, news and e-mail services compete with
services provided by America Online, Inc. ("America Online"), Prodigy Services
Co. ("Prodigy") and numerous Internet service providers. Premiere's paging
services compete with paging services offered by companies such as AT&T and
MCI.     
   
  Premiere's Orchestrate service, which Premiere intends to begin marketing
during the first quarter of 1998, is expected to compete with products offered
by companies such as Octel, Microsoft Corp. ("Microsoft"), Novell, Inc.
("Novell"), Lucent Technologies, Inc. ("Lucent") and numerous other entities.
For example, Octel and Microsoft recently announced a service, called "Unified
Messenger," which places all voice mail, e-mail and fax messages in a single
mailbox accessible by computer or telephone and MCI recently announced a
service, called "networkMCI Contact," which provides users a toll-free number
for their direct calls, voicemail, fax and paging and allows users to access
their messages through a telephone or the Internet. In addition, the number of
companies offering call center technology, including AT&T, MCI and Lucent, has
grown dramatically over the past few years, primarily in response to major
outsource initiatives and significantly lower technology costs. Premiere
expects that other parties will develop and implement information and
telecommunications service platforms similar to its platform, thereby
increasing competition for Premiere's services.     
   
  Xpedite's fax communication services currently compete with services
provided by each of AT&T, MCI and Sprint, and many of the national postal,
telephone and telegraph companies ("PTTs") around the world. Neither Premiere
nor Xpedite can predict whether AT&T, MCI, Sprint, any Internet service
provider or PTT or any other competitor will expand its fax communications
services business, and there can be no assurance that these or other
competitors will not commence or expand their businesses. Moreover, Xpedite's
receiving, queuing, routing and other systems logic and architecture are not
proprietary to Xpedite and as a result, there can be no assurance that such
information will not be acquired or duplicated by Xpedite's existing and
potential competitors. Xpedite does not typically have long-term contractual
agreements with its customers, and there can be no assurance that its
customers will continue to transact business with Premiere in the future. In
addition, even if there is continued growth in the use of electronic document
distribution services, there can be no     
 
                                      30
<PAGE>
 
assurance that potential customers will not elect to use their own equipment
to fulfill their needs for electronic document distribution services. There
also can be no assurance that customers will not elect to use alternatives to
Xpedite's electronic document distribution services, including the Internet,
to carry such customers' communications or that companies offering such
alternatives will not develop product features or pricing policies which are
more attractive to customers than those currently offered by Xpedite.
 
  Furthermore, on February 8, 1996, President Clinton signed into law the 1996
Act, which allows LECs, including the RBOCs, to provide inter-LATA long
distance telephone service, which will likely significantly increase
competition for long distance services. The new legislation also grants the
FCC the authority to deregulate other aspects of the telecommunications
industry, which in the future may, if authorized by the FCC, facilitate the
offering of an integrated suite of information and telecommunications services
by regulated entities, including the RBOCs, in competition with Premiere. Such
increased competition could have a material adverse effect on Premiere's
business, financial condition and results of operations.
 
  Telecommunications companies compete for consumers based on price, with
major long distance carriers conducting extensive advertising campaigns to
capture market share. There can be no assurance that a decrease in the rates
charged for communications services by the major long distance carriers or
other competitors, whether caused by general competitive pressures or the
entry of the RBOCs and other LECs into the long distance market, would not
have a material adverse effect on Premiere's business, financial condition and
results of operations.
 
  Premiere expects that the information and telecommunications services
markets will continue to attract new competitors and new technologies,
possibly including alternative technologies that are more sophisticated and
cost effective than the technology of Premiere. Premiere does not have the
contractual right to prevent its Premiere WorldLink subscribers from changing
to a competing network, and Premiere's subscribers may generally terminate
their service with Premiere at will.
 
RISKS OF LEVERAGE
   
  In connection with the issuance of its convertible notes to the public on
June 30 and July 30, 1997 (the "Convertible Notes"), Premiere incurred $172.5
million in indebtedness. As a result of this increased leverage, Premiere's
principal and interest obligations have increased substantially. The degree to
which Premiere is leveraged could adversely affect Premiere's ability to
obtain additional financing for working capital, acquisitions or other
purposes and could make it more vulnerable to economic downturns and
competitive pressures. Premiere's increased leverage could also adversely
affect its liquidity, as a substantial portion of available cash from
operations may have to be applied to meet debt service requirements, and in
the event of a cash shortfall, Premiere could be forced to reduce other
expenditures and forego potential acquisitions to be able to meet such
requirements. The indenture related to the Convertible Notes does not contain
any financial covenants or any other agreements restricting the payments of
dividends, the repurchase of securities of Premiere, the issuance of
additional equity or the incurrence of additional indebtedness.     
 
FACTORS AFFECTING OPERATING RESULTS; POTENTIAL FLUCTUATIONS IN QUARTERLY
RESULTS
 
  Premiere's operating results have varied significantly in the past and may
vary significantly in the future. Special factors that may cause Premiere's
future operating results to vary include: (i) the unique nature of strategic
relationships into which Premiere may enter in the future; (ii) changes in
operating expenses resulting from such strategic relationships and other
factors; (iii) the continued acceptance of Premiere's licensing program; (iv)
the financial performance of Premiere's licensees; (v) the timing of new
service announcements; (vi) market acceptance of new and enhanced versions of
Premiere's services; (vii) potential acquisitions; (viii) changes in
legislation and regulation that may affect the competitive environment for
Premiere's communications services; and (ix) general economic and seasonal
factors. In the future, revenues from Premiere's strategic relationships may
become an increasingly significant portion of Premiere's total revenues. Due
to the unique nature of each strategic relationship, these relationships may
change Premiere's mix of expenses relative to revenues.
 
 
                                      31
<PAGE>
 
  Quarterly revenues are difficult to forecast because the market for
Premiere's services is rapidly evolving. Premiere's expense levels are based,
in part, on its expectations as to future revenues. If revenue levels are
below expectations, Premiere may be unable or unwilling to reduce expenses
proportionately and operating results would likely be adversely affected. As a
result, Premiere believes that period-to-period comparisons of its results of
operations are not necessarily meaningful and should not be relied upon as
indications of future performance. Due to all of the foregoing factors, it is
likely that in some future quarter Premiere's operating results will be below
the expectations of public market analysts and investors. In such event, the
market price of Premiere Common Stock will likely be materially adversely
affected.
 
REGISTRATION RIGHTS
 
  Prior to Premiere's initial public offering in March 1996, Premiere granted
certain registration rights to holders of convertible preferred stock and
warrants. Although these contractual rights remain in force, the shares
subject to such registration rights may be freely disposed of pursuant to Rule
144 under the Securities Act.
   
  Subsequent to Premiere's initial public offering, Premiere has granted
registration rights in connection with Premiere's execution of a strategic
alliance agreement with WorldCom, and Premiere's acquisitions of TeleT
Communications LLC ("TeleT"), the Voice-Tel Entities and VoiceCom. In each of
these instances, Premiere is required to notify the holders of registration
rights of Premiere's intent to register any Premiere Common Stock under the
Securities Act and allow such holders an opportunity to include their shares
of Premiere Common Stock in such registration; provided, however, that: (i)
with respect to WorldCom and VoiceCom, such notice must be given only if
Premiere intends to register and sell newly issued shares; (ii) with respect
to CMG@Ventures, L.P. ("CMG"), such notice must be given only if 20% of the
shares held by CMG remain outstanding; and (iii) with respect to the former
owners of the Voice-Tel Entities, such notice must be given only until April
30, 1998. These registrations rights are subject to certain limitations and
restrictions, including the right of the underwriters of an underwritten
offering to limit the number of shares offered in such registration if such
underwriter determines that the number of shares requested to be registered
cannot be underwritten.     
   
  WorldCom has a one-time right to require Premiere to file a registration
statement under the Securities Act, provided that such request is made: (i)
between November 13, 1998 and November 13, 1999; or (ii) within 60 days from
the date of a change in control of Premiere, the termination of either Boland
T. Jones or D. Gregory Smith as executive officers or the termination of the
strategic alliance agreement with WorldCom if the events described in clause
(ii) occur prior to November 13, 1999. WorldCom has waived its right to
require Premiere to file a registration statement under the Securities Act as
a result of Mr. Smith's resignation. See "Risk Factors--Dependence on Key
Personnel." In addition, the registration must be with respect to such minimum
number of shares of Premiere Common Stock having an aggregate proposed
offering price equal to $10.0 million.     
   
  With respect to the former owners of the Voice-Tel Entities, such persons
collectively had the one-time demand right to require Premiere to use all
reasonable efforts to file a registration statement under the Securities Act.
On December 23, 1997, a Registration Statement on Form S-3 was declared
effective in connection with the exercise of such demand rights by the Voice-
Tel holders and on December 30, 1997 the Voice-Tel holders sold approximately
921,500 shares of Premiere Common Stock. In addition, Premiere agreed to file
a shelf registration statement (the "Voice-Tel Shelf") as soon as practicable
following December 15, 1997 to include any shares of Premiere Common Stock
then held by the former owners of the Voice-Tel Entities. These stockholders
may include up to approximately 6.4 million shares in the Voice-Tel Shelf.
Premiere has exercised certain contractual rights to postpone the Voice-Tel
Shelf for up to 90 days.     
   
  With respect to the former VoiceCom shareholders, Premiere has agreed to
file a shelf registration statement (the "VoiceCom Shelf") on or before the
date that is 30 days after the date Premiere files its Annual Report on Form
10-K for the fiscal year ended December 31, 1997. These shareholders may
include up to approximately 446,000 shares in the VoiceCom Shelf. Premiere has
the contractual right to postpone the VoiceCom Shelf under certain
circumstances.     
 
 
                                      32
<PAGE>
 
   
  No prediction can be made as to the effect, if any, that the availability of
additional shares for sale will have on the market prices of the Premiere
Common Stock prevailing from time to time. Nevertheless, sales of substantial
amounts of the Premiere Common Stock in the public market could adversely
affect prevailing market prices of the Premiere Common Stock and the ability
of Premiere to raise equity capital in the future.

Xpedite, see "The Merger--Registration Rights."
 
ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF PREMIERE'S ARTICLES, BYLAWS AND
THE GEORGIA BCC
 
  The Board of Directors of Premiere is empowered to issue preferred stock
without shareholder action. The existence of this "blank-check" preferred
could render more difficult or discourage an attempt to obtain control of
Premiere by means of a tender offer, merger, proxy contest or otherwise.
Premiere's Bylaws divide the Board of Directors into three classes, as nearly
equal in size as possible, with staggered three-year terms. One class is
elected each year. The classification of the Board of Directors could have the
effect of making it more difficult for a third party to acquire control of
Premiere. Premiere is also subject to certain provisions of the Georgia BCC,
which relate to business combinations with interested shareholders. In
addition to considering the effects of any action on Premiere and its
shareholders, Premiere's Articles permit the Premiere Board of Directors and
the committees and individual members thereof to consider the interests of
various constituencies, including employees, customers, suppliers, and
creditors of Premiere, communities in which Premiere maintains offices or
operations and other factors which such directors deem pertinent, in carrying
out and discharging the duties and responsibilities of such positions and in
determining what is believed to be in the best interests of Premiere.

XPEDITE SPECIAL MEETING
   
  The Xpedite Special Meeting will be held at 10:00 a.m., local time, on
February 27, 1998, at the Sheraton Eatontown Hotel and Conference Center,
Route 35 & Industrial Way East, Eatontown, New Jersey 07724. At the Xpedite
Special Meeting, Xpedite's stockholders will consider and vote upon a proposal
to adopt the Merger Agreement and transact such other business as may properly
come before the Xpedite Special Meeting.     
   
  Xpedite's Board of Directors has fixed the close of business on January 23,
1998, as the record date for determining the Xpedite stockholders entitled to
receive notice of and to vote at the Xpedite Special Meeting. Only holders of
record of Xpedite Common Stock as of the Xpedite Record Date are entitled to
notice of and to vote at the Xpedite Special Meeting. As of the close of
business on the Xpedite Record Date, there were 9,083,473 shares of Xpedite
Common Stock issued and outstanding held by approximately 122 holders of
record. Holders of Xpedite Common Stock are entitled to one vote on each
matter considered and voted on at the Xpedite Special Meeting for each share
of Xpedite Common Stock held of record at the close of business on the Xpedite
Record Date. The presence in person or by proxy of a majority of the votes
entitled to be cast at the Xpedite Special Meeting by holders of Xpedite
Common Stock will constitute a quorum for purposes of conducting business at
the Xpedite Special Meeting. Abstentions will be counted as shares present for
purposes of determining the presence of a quorum but will not be counted as
votes cast for purposes of determining whether a proposal has received
sufficient votes for adoption. Consequently, abstentions will have the effect
of a vote against the adoption of the Merger Agreement.     
 
  Proxies in the form enclosed are solicited by Xpedite's Board of Directors.
Shares of Xpedite Common Stock represented by properly executed proxies, if
such proxies are received in time and are not revoked, will be voted in
accordance with the instructions indicated on the proxies. IF NO INSTRUCTIONS
ARE INDICATED, SUCH PROXIES WILL BE VOTED FOR ADOPTION OF THE MERGER
AGREEMENT, AND AS DETERMINED BY THE PROXIES NAMED THEREIN AS TO ANY OTHER
MATTER THAT MAY PROPERLY COME BEFORE THE XPEDITE SPECIAL MEETING.
 
  An Xpedite stockholder who has given a proxy may revoke it at any time prior
to its exercise at the Xpedite Special Meeting by (i) giving written notice of
revocation to the Corporate Secretary of Xpedite, (ii) properly submitting to
Xpedite a duly executed proxy bearing a later date, or (iii) voting in person
at the Xpedite Special Meeting. All written notices of revocation and other
communications with respect to revocation of proxies should be addressed to
Xpedite as follows: Xpedite Systems, Inc., One Industrial Way West, Eatontown,
New Jersey 07724, Attention: Corporate Secretary. A proxy appointment will not
be revoked by death or supervening incapacity of the stockholder executing the
proxy unless, before the shares are voted, notice of such death or incapacity
is filed with Xpedite's Corporate Secretary or other person responsible for
tabulating votes on behalf of Xpedite.
 
  The expense of soliciting proxies for the Xpedite Special Meeting will be
borne by Xpedite. In addition to the solicitation of stockholders of record by
mail, telephone or personal contact, Xpedite will be contacting brokers,
dealers, banks or voting trustees or their nominees who can be identified as
record holders of Xpedite Common Stock. Such holders, after inquiry by
Xpedite, will provide information concerning the quantity of proxy and other
materials needed to supply such materials to beneficial owners, and Xpedite
will reimburse them for the expense of mailing the proxy materials to such
persons.
   
  The affirmative vote of the majority of the outstanding shares of Xpedite
Common Stock entitled to vote thereon will be required for adoption of the
Merger Agreement. As of the close of business on the Xpedite Record Date, the
Locked-Up Stockholders held an aggregate of 2,976,941 shares of Xpedite Common
Stock, or approximately 32.8% of the outstanding Xpedite Common Stock.
Pursuant to the Stockholder Agreements, the Locked-Up Stockholders have agreed
to vote the shares of Xpedite Common Stock owned by them on the Xpedite Record
Date in favor of adoption of the Merger Agreement. See "The Merger--
Stockholder Agreements."

  HOLDERS OF XPEDITE COMMON STOCK SHOULD NOT SEND IN THEIR CERTIFICATES
REPRESENTING SHARES OF XPEDITE COMMON STOCK UNTIL THEY RECEIVE THE LETTER OF

PREMIERE SPECIAL MEETING
   
  The Premiere Special Meeting will be held at 10:00 a.m., local time, on
February 27, 1998 at the Terrace Garden Inn, 3405 Lenox Road, N.E., Atlanta,
Georgia 30326. At the Premiere Special Meeting, holders of Premiere Common
Stock will consider and vote upon proposals to approve the issuance of shares
of Premiere Common Stock pursuant to the Merger Agreement and to approve the
Stock Plan Amendment, and will transact such other business as may properly
come before the Premiere Special Meeting.     
   
  Premiere's Board of Directors has fixed the close of business on January 23,
1998, as the record date for determining the holders of Premiere Common Stock
and Premiere Preferred Stock entitled to receive notice of and to vote at the
Premiere Special Meeting. Only holders of record of Premiere Common Stock and
Premiere Preferred Stock as of the Premiere Record Date are entitled to notice
of and to vote at the Premiere Special Meeting. As of the close of business on
the Premiere Record Date, there were 33,966,198 shares of Premiere Common
Stock issued and outstanding and held by approximately 539 holders of record
and one share of Premiere Preferred Stock held of record by one holder.
Holders of Premiere Common Stock are entitled to one vote on each matter
considered and voted on at the Premiere Special Meeting for each share of
Premiere Common Stock held of record at the close of business on the Premiere
Record Date. The holder of the outstanding share of Premiere Preferred Stock
is entitled to the number of votes that the holders of the Exchangeable Shares
would be entitled to cast if all such Exchangeable Shares were exchanged. As
of the Premiere Record Date, 329,840 Exchangeable Shares were outstanding. See
"Certain Differences in the Rights of Premiere and Xpedite Stockholders--
Voting Rights." The presence in person or by proxy of majority of the votes
entitled to be cast by holders of Premiere Common Stock and Premiere Preferred
Stock will constitute a quorum for purposes of conducting business at the
Premiere Special Meeting. As of the Premiere Record Date, Premiere's directors
and executive officers and their affiliates beneficially owned approximately
13.7% of the outstanding shares of Premiere Common Stock entitled to vote at
the Premiere Special Meeting. Abstentions will be counted as shares present
for purposes of determining the presence of a quorum but will not be counted
as votes cast for purposes of determining whether a proposal has received
sufficient votes for adoption. Consequently, abstentions will have no effect
on the required vote for approval of such proposals.     
 
  Proxies in the form enclosed are solicited by Premiere's Board of Directors.
Shares of Premiere Common Stock and Premiere Preferred Stock represented by
properly executed proxies, if such proxies are received in time and are not
revoked, will be voted in accordance with the instructions indicated on the
proxies. IF NO INSTRUCTIONS ARE INDICATED, SUCH PROXIES WILL BE VOTED FOR
APPROVAL OF THE ISSUANCE OF SHARES OF PREMIERE COMMON STOCK PURSUANT TO THE
MERGER AGREEMENT AND FOR APPROVAL OF THE STOCK PLAN AMENDMENT, AND AS
DETERMINED BY A MAJORITY OF THE MEMBERS OF THE PREMIERE BOARD OF DIRECTORS AS
TO ANY OTHER MATTER THAT MAY PROPERLY COME BEFORE THE PREMIERE SPECIAL
MEETING.
   
  A Premiere stockholder who has given a proxy may revoke it at any time prior
to its exercise at the Premiere Special Meeting by (i) giving written notice
of revocation to the Corporate Secretary of Premiere, (ii) properly submitting
to Premiere a duly executed proxy bearing a later date, or (iii) voting in
person at the Premiere Special Meeting. All written notices of revocation and
other communications with respect to revocation of proxies should be addressed
to Premiere as follows: Premiere Technologies, Inc., 3399 Peachtree Road,
N.E., Lenox Building, Suite 600, Atlanta, Georgia 30326, Attention: Corporate
Secretary. A proxy appointment will not be revoked by death or supervening
incapacity of the stockholder executing the proxy unless, before the shares
are voted, notice of such death or incapacity is filed with Premiere's
Corporate Secretary or other person responsible for tabulating votes on behalf
of Premiere.

  The expense of soliciting proxies for the Premiere Special Meeting will be
paid by Premiere. The solicitation of proxies may be made by directors,
officers and employees of Premiere in person or by mail, telephone or
facsimile without additional compensation payable thereto. Arrangements have
been made with brokerage houses and other custodians, nominees or fiduciaries
to forward proxy solicitation materials to the beneficial owners of Premiere
Common Stock held of record by such persons, and Premiere will reimburse them
for reasonable expenses incurred by them in so doing. In addition, Premiere
has engaged the services of Morrow & Co., Inc. to act as a proxy solicitor.
    
  The affirmative vote of the majority of the votes cast by the holders of
shares of Premiere Common Stock and Premiere Preferred Stock, voting together
as a single class, is required for approval of the issuance of the shares of
Premiere Common Stock in the Merger and for approval of the Stock Plan
Amendment.
 
  If proposal (1) set forth on the enclosed form of proxy of Premiere does not
receive the requisite number of votes for approval, the Merger will not be
consummated. If proposal (2) set forth on the enclosed form of proxy of
Premiere does not receive the requisite number of votes for approval, the
Stock Plan Amendment will not be consummated.

                                THE MERGER     
 
  The following information describes certain information pertaining to the
Merger. This description does not purport to be complete and is qualified in
its entirety by reference to the Annexes hereto, including the Merger
Agreement, a copy of which is set forth in Annex A to this Joint Proxy
Statement/Prospectus and incorporated herein by reference. All stockholders of
Xpedite and Premiere are urged to read the Annexes in their entirety.
 
GENERAL
 
  Subject to the terms and conditions of the Merger Agreement, Acquisition Sub
will merge with and into Xpedite, which will be the surviving corporation of
the Merger and, as a result thereof, will become a wholly owned subsidiary of
Premiere. Upon consummation of the Merger, each outstanding share of Xpedite
Common Stock (excluding shares held by Xpedite in its treasury) will cease to
be outstanding and will be converted into the right to receive a number of
shares of Premiere Common Stock equal to the Exchange Ratio, with cash being
paid in lieu of any fractional share interest. The Exchange Ratio shall be
determined by dividing $34.00 by the average of the daily last sale prices of
Premiere Common Stock as reported on Nasdaq for the 20 consecutive trading
days on which shares of Premiere Common Stock are actually traded as over-the-
counter securities and quoted on Nasdaq ending on the trading day immediately
preceding the Xpedite Special Meeting (the "Average Closing Price"); provided,
that except in certain circumstances (see "The Merger--Termination and
Possible Exchange Ratio Increase"), the Exchange Ratio will not be higher than
1.25 (corresponding to the Minimum Average Closing Price) or lower than .867
(corresponding to the Maximum Average Closing Price). See "--Merger
Consideration."
   
  Consummation of the Merger is subject to various conditions, including among
other matters: (i) adoption of the Merger Agreement by the requisite vote of
the holders of Xpedite Common Stock; (ii) approval of the issuance of shares
of Premiere Common Stock pursuant to the Merger Agreement by the requisite
vote of the holders of Premiere Common Stock and Premiere Preferred Stock
voting together as a single class; (iii) receipt of all governmental and other
consents and approvals necessary to permit consummation of the Merger;
(iv) receipt by Premiere of letters from Arthur Andersen and Ernst & Young
dated as of the Effective Time to the effect that such firms are not aware of
any matters relating to the Merger or Xpedite which would preclude the Merger
from qualifying for pooling-of-interests accounting treatment;
(v) consummation of the XSL Acquisition (which occurred on December 17, 1997);
and (vi) satisfaction of certain other usual conditions. See "--Conditions to
Consummation," "--Regulatory Approvals," "--Termination and Possible Exchange
Ratio Increase" and "--Amendment and Waiver." A copy of the Merger Agreement
is set forth in Annex A to this Joint Proxy Statement/Prospectus.     
 
EFFECTIVE TIME
 
  Assuming satisfaction or waiver (if permitted) of all conditions to the
consummation of the Merger, the Merger is expected to become effective during
the first quarter of 1998. The Effective Time will occur when a certificate of
merger reflecting the Merger is duly filed with the Secretary of State of
Delaware. Either Premiere or Xpedite may terminate the Merger Agreement if the
Merger has not been consummated by April 30, 1998, provided that the date will
be extended until May 30, 1998, if the Joint Proxy Statement/Prospectus has
been mailed to the stockholders of both Xpedite and Premiere before April 30,
1998, and provided further that the right to so terminate the Merger Agreement
will not be available to any party whose failure to fulfill any obligation
under the Merger Agreement resulted in the failure of the Merger to occur on
or before such date. See "--Conditions to Consummation," "--Regulatory
Approvals," and "--Termination and Possible Exchange Ratio Increase."

BACKGROUND OF THE MERGER
 
 Xpedite
 
  During 1995 and 1996, on various occasions a number of significant
stockholders of Xpedite, including certain investment funds managed by
Patricof & Co. Ventures, Inc. (the "Patricof Stockholders"), David, Stuart and
Robert Epstein (collectively, the "Epstein Stockholders") and certain other
stockholders (the "SVC Stockholders") which had acquired Xpedite Common Stock
in connection with their sale of the SVC Companies to Xpedite, expressed to
the Xpedite Board and senior management the view that (i) they believed that
because the market price of Xpedite Common Stock had failed to rise to levels
predicted by certain industry analysts, the value of Xpedite Common Stock was
not being accurately reflected in the market price of Xpedite Common Stock,
(ii) Xpedite's stockholders were unable to achieve liquidity at the then
prevailing market prices of Xpedite Common Stock, and (iii) accordingly,
Xpedite should explore strategic alternatives to enhance stockholder value.
 
  Based upon the foregoing, (i) certain members of senior management of
Xpedite began in the fall of 1996, with the approval of Xpedite's Board, to
explore the possibility of making a proposal to acquire Xpedite, and (ii) on
February 5, 1997, Xpedite's Board appointed a Special Strategic Committee (the
"Special Committee"), consisting of Philip A. Campbell ("Campbell") and Robert
Chefitz ("Chefitz"), to evaluate the strategic opportunities and alternatives
available to Xpedite for enhancing stockholder value (collectively, the
"Strategic Alternatives").
 
  On February 7, 1997, after interviewing a number of prominent investment
banking firms, the Special Committee engaged Merrill Lynch to act as
independent investment banker to the Special Committee and to advise the
Special Committee with respect to Xpedite's Strategic Alternatives.
 
  In connection with senior management's exploration of the possibility of
making a proposal to acquire Xpedite, they contacted UBS, which expressed an
interest in such a transaction and, after introducing senior management to
Fenway, such members of senior management, UBS and Fenway proceeded with their
exploration of such a transaction. On February 7, 1997, UBS, Fenway and
certain members of senior management of Xpedite, including Roy B. Andersen,
Jr. ("Andersen"), Robert S. Vaters, Max A. Slifer, Dennis Schmaltz and George
Abi Zeid (collectively, the "MBO Group"), made an offer (the "MBO Proposal")
to acquire Xpedite for $22.50 per share in cash, subject to satisfaction of a
number of conditions, including, but not limited to, (i) the acquisition by
Xpedite of XSL (the "XSL Acquisition Condition") and Xpedite Germany, (ii) the
satisfactory completion of a due diligence investigation of Xpedite by the MBO
Group and (iii) the approval of the acquisition by Xpedite's Board.
 
  Following receipt of the MBO Proposal, the Special Committee instructed
Merrill Lynch to conduct a process to identify additional bidders and solicit
additional bids to purchase Xpedite. Throughout February, March and April
1997, Merrill Lynch conducted such process.
 
  In February and March 1997, the Special Committee engaged in preliminary
discussions with the shareholders of XSL (the "XSL Shareholders") in an
attempt to agree on terms and conditions under which Xpedite could acquire
XSL. As the parties were unable to agree on the price payable for XSL, these
discussions were not extensive and produced no agreements as to any such terms
or conditions. Further, in addition to conducting the process referred to
herein, Merrill Lynch advised the Special Committee and the Xpedite Board as
to the other Strategic Alternatives which were available to Xpedite. Such
Strategic Alternatives were discussed by the Special Committee with its legal
and financial advisors and the Xpedite Board throughout the process described
herein.
 
  On or about April 1, 1997, Merrill Lynch invited interested parties to
submit preliminary indications of interest in pursuing the acquisition of
Xpedite. On April 21, 1997, Merrill Lynch reported to the Special Committee
that three additional parties had submitted indications of interest in
acquiring Xpedite. Previously, on April 16, 1997, the MBO Group confirmed to
the Special Committee that it continued to be interested in acquiring Xpedite.
 
                                      38
<PAGE>
 
  Of the parties which had submitted indications of interest in acquiring
Xpedite, only the MBO Group submitted a final offer to purchase Xpedite.
 
  On July 7, 1997, the MBO Group submitted an offer to acquire Xpedite for
$22.50 per share in cash (the "Final MBO Offer"). From July 7 through July 10,
1997, the Special Committee and its advisors extensively discussed the Final
MBO Offer with the MBO Group.
 
  On July 11, 1997, the MBO Group amended the Final MBO Offer (the "Amended
Final MBO Offer") to, among other things, increase the per share purchase
price to $23.00, assuming a purchase price for XSL of $85 million; provided
that the aggregate purchase price for shares of Xpedite Common Stock would be
reduced by 50% of any amount by which the purchase price for XSL exceeded $85
million, but not below $22.50 per share.
 
  From July 11 through August 7, the Special Committee and its advisors
extensively discussed the Amended Final MBO Offer with the MBO Group.
 
  On July 18, 1997, the Xpedite Board met via telephonic conference call to
discuss the status of negotiations with the MBO Group and the transaction with
XSL. It was determined that consummating a transaction to acquire XSL at a
negotiated purchase price was beneficial to Xpedite (whether or not
negotiations with the MBO Group were to be successful) and the Xpedite Board
instructed the Special Committee to continue negotiations with the
shareholders of XSL. Beginning July 20, 1997, the Special Committee and
Andersen engaged in further extensive discussions with the XSL Shareholders
regarding the purchase by Xpedite of XSL.
 
  On August 6, 1997, the Xpedite Board held a special meeting to consider the
XSL Acquisition. Andersen and Xpedite's legal advisors explained in detail the
material terms of the XSL Purchase Agreement and related agreements. In
addition, Merrill Lynch made a presentation regarding the financial aspects of
the XSL Acquisition. After extensive discussion and consideration, the members
of Xpedite's Board in attendance at the meeting unanimously approved the XSL
Acquisition, the XSL Purchase Agreement and related agreements, and the
transactions contemplated thereby, and authorized execution of such
agreements.
 
  On August 7, 1997, Andersen and Xpedite's legal advisors (i) negotiated the
final details of the XSL Purchase Agreement and related agreements, and (ii)
finalized the terms of the Prior Merger Agreement and related agreements.
Also, on August 7, 1997, the Special Committee conducted a telephonic meeting
with the MBO Group to discuss the final terms of the Prior Merger Agreement,
including the price per share to be paid to acquire Xpedite. The MBO Group
proposed, among other things to pay $23.25 per share of Xpedite Common Stock
(the "Cash Price") to be acquired pursuant to the Prior Merger Agreement.
After the receipt of the MBO Group's proposal, after negotiation of such
proposal and after consultation with the Special Committee and its financial
and legal advisors, the Special Committee agreed to present the MBO Group's
proposal to the Xpedite Board.
   
  On August 8, 1997, the Xpedite Board held a special meeting to consider the
Prior Merger Agreement. Since Andersen was a member of the MBO Group, he did
not participate in or vote at such meeting, but was available by telephone to
answer questions. Xpedite's legal advisors reviewed the material terms of the
Prior Merger Agreement. Merrill Lynch reviewed the process it had conducted at
the instruction of the Special Committee to identify bidders for Xpedite,
reviewed the financial aspects of the Prior Merger Agreement, discussed
Strategic Alternatives other than the transactions contemplated by the Prior
Merger Agreement, and delivered their oral opinion (subsequently confirmed in
writing) to the Xpedite Board that, as of such date, based upon and subject to
the matters set forth in its written opinion (the form of which was
substantially similar to the form of the Merrill Lynch Opinion), the Cash
Price to be received by Xpedite's stockholders in the proposed merger
transaction contemplated by the Prior Merger Agreement was fair, from a
financial point of view. After further discussions and consideration, the
members of the Xpedite Board in attendance unanimously approved the Prior
Merger Agreement and the transactions contemplated thereby.     
 
  The Prior Merger Agreement and the XSL Purchase Agreement were executed and
announced on August 8, 1997.
 
                                      39

  On October 24, 1997, Premiere informed the Special Committee that it would
be prepared to enter into an agreement pursuant to which it would acquire
Xpedite for $26.00 per share in Premiere Common Stock or a combination of
Premiere Common Stock and cash. Premiere's unsolicited indication of interest
(the "Premiere Proposal") was nonbinding and subject to certain conditions,
including completion of due diligence and a mutually acceptable merger
agreement. Additionally, the Premiere Proposal stipulated that Premiere would
be prepared to offer Xpedite stockholders additional value if a combination
could be accounted for as a pooling of interests.
 
  On each of October 25, 1997, and October 26, 1997, the Xpedite Board (along
with its financial and legal advisors) held a special meeting by telephone to
consider the Premiere Proposal, and conducted extensive discussions regarding
the Premiere Proposal and the status of the transactions contemplated by the
Prior Merger Agreement. Since Andersen was a member of the MBO Group, he did
not participate in any of the Xpedite Board deliberations regarding the
Premiere Proposal (or the Premiere Offer or the Final Premiere Offer, as
defined below), except as described below. On October 26, 1997, Premiere and
Xpedite entered into a mutual confidentiality agreement. On October 27, 1997,
Xpedite's Board (along with its financial and legal advisors) held a special
meeting by telephone to discuss the Premiere Proposal and Premiere's request
to commence a due diligence investigation of Xpedite. On October 28, 1997,
Premiere began its due diligence investigation of Xpedite, including (i)
meetings with Chefitz, certain of Xpedite's executive officers and Xpedite's
legal and financial advisors, and (ii) review of certain of Xpedite's
nonpublic information. Later on October 28, 1997, the Xpedite Board (along
with its financial and legal advisors) held a special meeting by telephone and
extensively discussed developments regarding the Premiere Proposal and
Xpedite. In addition, on October 29, 1997, Premiere subsequently informed
Xpedite's financial and legal advisors that it intended to make a definitive
offer to purchase Xpedite in a stock-for-stock transaction which Premiere
believed would qualify to be treated as a pooling of interests for accounting
purposes. Also on October 29, 1997, the Xpedite Board (along with its
financial and legal advisors) held a special meeting by telephone to review
developments regarding the Premiere Proposal and the status of the merger
transaction contemplated by the Prior Merger Agreement.
 
  Premiere continued to conduct an extensive due diligence investigation of
Xpedite after October 29, 1997.
 
  Beginning on October 31, 1997, Xpedite began to conduct an extensive due
diligence investigation of Premiere. Xpedite's legal advisors began their
investigation of Premiere on such day. On November 3 and 4, 1997, certain of
Xpedite's executive officers, three non-management members of the Xpedite
Board and representatives of Merrill Lynch traveled to Premiere's headquarters
to conduct an investigation of Premiere. Separately, representatives of Ernst
& Young (Xpedite's accountants) assisted Xpedite in its due diligence of
Premiere at Premiere's offices and by telephone.
 
  On the evening of November 4, 1997, Premiere presented an offer to acquire
Xpedite for a purchase price of $30 per share in Premiere Common Stock (the
"Premiere Offer"). The Premiere Offer was subject to the same conditions as
those contained in the Premiere Proposal. Premiere intended the transaction
contemplated by the Premiere Offer to be accounted for as a pooling of
interests.
 
  On November 5, 1997, the Xpedite Board (along with its legal and financial
advisors) held a special meeting by telephone to discuss the Premiere Offer,
the transactions contemplated by the Prior Merger Agreement and the progress
of the due diligence investigation of Premiere. Also, beginning on November 5,
1997, and continuously thereafter, Xpedite and Premiere began to discuss the
terms of a definitive merger agreement between them, and to fulfill certain of
the conditions set forth in the Premiere Offer.
 
  On November 7 and 10, 1997, the Xpedite Board (along with its legal and
financial advisors) held special meetings by telephone to consider the
Premiere Offer and conducted extensive discussions regarding Premiere, the
Premiere Offer and the status of the proposed merger transaction contemplated
by the Prior Merger Agreement.
 
  On November 11, 1997, the Xpedite Board (along with its accounting,
financial and legal advisors) held a special meeting by telephone to consider
the Premiere Offer and conducted extensive discussions regarding
 
                                      40
<PAGE>
 
Premiere, the Premiere Offer and the status of the proposed merger transaction
contemplated by the Prior Merger Agreement. Andersen participated in a segment
of this meeting in order to discuss, among other things, his views regarding
the strategic benefits which could result from a combination of Xpedite and
Premiere. During this meeting, the Xpedite Board discussed the possibility
that the MBO Group might make a new offer to acquire Xpedite for an amount in
cash in excess of $23.25. The Xpedite Board instructed Merrill Lynch to
solicit such a bid, and in general to strongly encourage both the MBO Group
and Premiere to make bids which would maximize value for Xpedite's
stockholders; the Xpedite Board also extensively discussed other factors,
including, but not limited to, (i) timing (i.e., how soon a transaction with
Premiere or the MBO Group could be consummated) and (ii) certainty (i.e., the
conditions to which a transaction with the MBO Group or Premiere would be
subject, and the likelihood that such conditions could be fulfilled and such
transaction consummated). The Xpedite Board also instructed Merrill Lynch to
use best efforts to maintain a "level playing field" between Premiere and the
MBO Group (i.e., not to favor one over the other) in order to encourage each
of Premiere and the MBO Group to make additional higher bids and to maximize
value for Xpedite's stockholders.
 
  On November 11, 1997, the Xpedite Board delivered to Premiere and to the MBO
Group a request that, to assist the Xpedite Board in discharging its fiduciary
duties with respect to the Prior Merger Agreement and the Offer, both Premiere
and the MBO Group submit to the Xpedite Board no later than 11:00 a.m. on
November 12, 1997, any additional information that might be necessary or
appropriate for the Xpedite Board to consider in evaluating the Prior Merger
Agreement and the Premiere Offer. The purpose of such request was to encourage
both Premiere and the MBO Group to increase the amounts they would offer to
acquire Xpedite.
 
  On November 11, 1997, at approximately 10:45 p.m., Premiere notified the
Xpedite Board that Premiere was increasing its offer to acquire Xpedite to $34
per share in a stock-for-stock merger, subject to the conditions contained in
the Premiere Offer (the "Revised Premiere Offer"). While the MBO Group
indicated that it might consider making a new offer to purchase Xpedite for
$27 per share in cash, the MBO Group did not formally submit such a bid or any
other information to the Xpedite Board.
 
  On November 12, 1997, Xpedite's legal and financial advisors continued to
discuss with Premiere the terms of a definitive merger agreement to fulfill
certain of the conditions set forth in the Revised Premiere Offer.
 
  On November 12, 1997, the Xpedite Board (along with its accounting, legal
and financial advisors) held a special meeting in the offices of its legal
advisors to consider the Revised Premiere Offer, and conducted extensive
discussions regarding the Revised Premiere Offer and the status of the
proposed merger transaction contemplated by the Prior Merger Agreement. The
Xpedite Board considered all aspects of the Revised Premiere Offer and
compared the Revised Premiere Offer to the proposed merger transaction
contemplated by the Prior Merger Agreement. In this regard, the Xpedite Board
was informed that the Patricof Stockholders and the Epstein Stockholders had
held discussions with the MBO Group in which the MBO Group indicated that it
would consider making a new offer to purchase Xpedite for $27 per share in
cash if, among other things, such stockholders would agree to give the MBO
Group an option to purchase such stockholders' shares of Xpedite Common Stock
for an exercise price per share equal to $27. Notwithstanding such
discussions, the MBO Group did not make a new offer to purchase Xpedite. Since
Andersen was a member of the MBO Group, he did not participate in such
meeting, but was available by telephone to answer questions.
 
  On November 13, 1997, the Xpedite Board (along with its accounting, legal
and financial advisors) held a special meeting in the offices of its legal
advisors to consider the Revised Premiere Offer. Since Andersen was a member
of the MBO Group, he did not participate in such meeting, but was available by
telephone to answer questions. Xpedite's legal advisors reviewed the material
terms of the proposed Merger Agreement with Premiere. Xpedite's accountants
reviewed the material accounting issues involved in the proposed Merger
Agreement. Merrill Lynch reviewed the terms of the Merger Agreement and
discussed the financial aspects of the Revised Premiere Offer, and delivered
its opinion to the Board that, as of November 13, 1997 and based upon and
subject to the matters set forth in its written opinion, the Merger
Consideration was fair, from a financial point of view, to the holders of
Xpedite Common Stock. After further discussion and consideration, the members
of the Xpedite Board in attendance unanimously agreed that the Merger was fair
to and in the best interest of Xpedite's
 
                                      41

stockholders and withdrew their recommendation of the proposed merger
transaction contemplated by the Prior Merger Agreement, authorized and
directed Xpedite to terminate the Prior Merger Agreement, approved the Merger
and the transactions contemplated thereby, and authorized and directed the
execution and delivery of the Merger Agreement.
 
  The Merger Agreement was executed after 11:00 p.m. on November 13, 1997, and
was announced on November 14, 1997.
 
  The Merger Consideration agreed to by the parties in the Merger Agreement
was the result of arm's length negotiations.
 
 Premiere
 
  Since 1996, Premiere has employed a strategy of growth through acquisitions
of complementary services, in addition to internal growth, to enhance
shareholder value. Premiere's strategy is to offer a portfolio of enhanced,
integrated personal communications services through a network-based service
bureau solution, including e-mail and Internet-based services, voice-
messaging, fax services, long distance calling card services and conference
calling. In September 1996, Premiere acquired TeleT to advance its development
of Orchestrate, a Web-based interface into Premiere's computer telephony
platform. In April, May and June 1997, Premiere acquired the Voice-Tel
Entities, which provide interactive digital voice messaging products on a
service bureau basis through approximately 210 POPs in the United States,
Puerto Rico, Canada, Australia and New Zealand. Premiere believes that the
Voice-Tel Acquisitions broaden Premiere's customer base by allowing Premiere
to offer local access to certain of its enhanced personal communications
services, as well as providing Premiere with a direct sales force of
approximately 300 persons in four countries, an expanded subscriber base and
the potential for greater cross-selling opportunities. In September 1997,
Premiere acquired VoiceCom, a provider of personal communications management
services and telecommunication outsourcing solutions to large corporations,
government entities and mobile professionals, including such services as voice
messaging, mobile communications, full-service conference calling and voice
response programming. The VoiceCom acquisition provides Premiere with Fortune
500 customers, an expanded corporate direct sales force and an opportunity to
cross-sell its service offerings to VoiceCom's customer base.
 
  Premiere has in 1997 continued to consider a number of strategic
acquisitions to complement Premiere's service offerings and to increase
shareholder value. In September 1997, representatives of Prudential Securities
met with representatives of Premiere management to discuss the potential
advantages of the possible acquisition of Xpedite. During October 1997,
Premiere's management reviewed publicly available information concerning
Xpedite and continued discussions with representatives of Prudential
Securities regarding a possible acquisition of Xpedite. On October 24, 1997,
Prudential Securities was formally retained by Premiere to act as its
financial advisor in connection with Premiere's consideration of a possible
acquisition of Xpedite and related matters.
 
  On October 23, 1997, Premiere's Board of Directors held a special meeting
and determined to consider further a possible combination with Xpedite and
directed Premiere management to express to the Special Committee an indication
of interest and to proceed with due diligence. On October 24, 1997,
Mr. Boland T. Jones, Chairman, President and Chief Executive Officer of
Premiere, sent a letter to the Special Committee expressing Premiere's
interest in considering a possible combination. On October 26, 1997, Premiere
and Xpedite entered into a mutual confidentiality agreement. Between October
28, 1997 and November 3, 1997, Premiere and its advisors conducted extensive
financial, operational and legal due diligence of Xpedite, and conducted due
diligence meetings with various members of Xpedite's management team and
Xpedite's financial, legal and accounting advisors. On October 31, 1997,
members of Premiere's management team conducted meetings with Xpedite's
management team to discuss a possible acquisition. On November 2, 1997,
representatives of Premiere submitted a draft Merger Agreement to
representatives of Xpedite.
 
  On November 3, 1997, the Board of Directors of Premiere held a special
meeting to receive a due diligence report from Premiere's management and
Premiere's financial, accounting and legal advisors, and to review
 
                                      42
<PAGE>
 
extensively the terms of a possible merger with Xpedite. These presentations
included information about Xpedite and its management team and reasons for the
proposed Merger and its benefits to Premiere. Premiere's legal advisors
discussed certain legal matters, including the requirement for approval by
Premiere stockholders for the issuance of shares of Premiere Common Stock in
connection with the Merger and the impact of certain statutory and regulatory
requirements, including antitrust approval under the HSR Act. Prudential
Securities made a presentation regarding the financial terms of a proposed
acquisition of Xpedite and expressed its preliminary view as to the fairness,
from a financial point of view, to Premiere of a range of proposed purchase
prices. After further extensive discussion and consideration of the factors
described below, the Premiere Board of Directors unanimously authorized
management to continue negotiations aimed at reaching definitive agreements
consistent with the terms presented and subject to completion of its due
diligence review.
 
  On November 4, 1997, Premiere and Xpedite management and Board members met,
along with financial, accounting and legal advisors, and on the evening of
November 4, 1997, Premiere presented the Premiere Offer to Xpedite. Between
November 4, 1997 and November 11, 1997, representatives of Premiere and
Xpedite negotiated extensively the terms of the Merger Agreement and ancillary
documents, and continued due diligence.
 
  On November 11, 1997, the Xpedite Board of Directors delivered to
representatives of Premiere a request that, to assist the Xpedite Board of
Directors in discharging its fiduciary duties to Xpedite's stockholders,
Premiere submit to the Xpedite Board no later than 11:00 a.m. on November 12,
1997, any additional information that may be necessary or appropriate for the
Xpedite Board to consider. On November 11, 1997, the Premiere Board of
Directors participated in a telephonic Board meeting, during which members of
Premiere's management reviewed the reasons for the Merger and the benefits to
Premiere and presented a summary of the final resolution of open issues in the
Merger Agreement and ancillary documents. Management also reviewed with the
Premiere Board information concerning its estimates of the likelihood and
expected range of a revised competing cash offer from the MBO Group.
Management discussed its views concerning the range of revised prices payable
in Premiere Common Stock necessary to counter any such competing cash offer
and its views concerning the appropriate timing of such a revised offer.
Prudential Securities reviewed the financial terms of the Merger Agreement as
adjusted to the proposed revised price level discussed at the meeting and
delivered its oral opinion to the Premiere Board of Directors to the effect
that, as of such date, the consideration to be paid by Premiere in the Merger
was fair, from a financial point of view, to Premiere. The Premiere Board
members participating in the telephonic meeting unanimously authorized
Premiere management to increase the Premiere Offer to a fixed value within the
price range considered by the Premiere Board of Directors, subject to
finalizing the negotiation of the Merger Agreement and various ancillary
documents related to the Merger Agreement. Premiere submitted to the Xpedite
Board the Revised Premiere Offer, subject to various conditions, at
approximately 10:45 p.m. on the evening of November 11, 1997.
 
  On November 12 and 13, 1997, representatives of Premiere and Xpedite
continued negotiations of the terms of the Merger Agreement. After 11:00 p.m.
on the evening of November 13, 1997, Premiere and Xpedite executed the Merger
Agreement and certain ancillary documents, and the Merger was announced on
November 14, 1997.
 
REASONS FOR THE MERGER
 
 Xpedite
 
  THE XPEDITE BOARD BELIEVES THAT THE MERGER IS FAIR TO, AND IN THE BEST
INTEREST OF, XPEDITE AND ITS STOCKHOLDERS. THE XPEDITE BOARD UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS OF
XPEDITE VOTE FOR ADOPTION OF THE MERGER AGREEMENT.
 
  In reaching its unanimous determination that the Merger Agreement and the
Merger are in the best interests of Xpedite and its stockholders, the Xpedite
Board considered a number of factors (both positive and negative), including
without limitation, the following:
 
 
                                      43
<PAGE>
 
     
    (i) the written opinion of Merrill Lynch that, as of such date and based
  upon and subject to the matters set forth in such written opinion, the
  Merger Consideration to be received by the holders of Xpedite Common Stock
  in the Merger was fair to such stockholders from a financial point of view
  (see "--Opinions of Financial Advisors; Xpedite");     
 
    (ii) the relationship of the Merger Consideration to (a) the historical
  market prices for the Xpedite Common Stock (see "Summary--Market Prices and
  Dividends") and (b) the Cash Price (i.e., $23.25 per share) payable
  pursuant to the Prior Merger Agreement;
 
    (iii) the Xpedite Board's view that the terms of the Merger Agreement, as
  reviewed by the Xpedite Board with its legal advisors and Merrill Lynch,
  are advisable and fair to Xpedite and its stockholders in light of the
  nature of the transaction and provided Xpedite and its stockholders with
  the flexibility to, under certain circumstances, accept a third party
  proposal for an Alternative Transaction (as defined in the Merger
  Agreement) and terminate the Merger Agreement (see "--Conduct of Business
  Pending Consummation" and "--Termination and Possible Exchange Ratio
  Increase" and "--Expenses and Termination Fees");
 
    (iv) information relating to the financial condition and results of
  operations of Xpedite (see "Summary--Selected Historical Consolidated
  Financial Data") and Xpedite's financial projections (see "--Opinions of
  Financial Advisors; Xpedite"), which, in the Xpedite Board's view,
  supported a determination that the Merger Consideration is fair to Xpedite
  and its stockholders;
 
    (v) the ability of Premiere to consummate the transactions contemplated
  by the Merger Agreement on a timely basis and the likelihood that the
  conditions to closing set forth in the Merger Agreement will be fulfilled;
 
    (vi) Xpedite's exploration of Strategic Alternatives for maximizing
  stockholder value, as described under "--Background of the Merger;
  Xpedite," and particularly the Xpedite Board's conclusion that, based upon
  such exploration, it appeared that such Strategic Alternatives, even if
  successfully carried to completion, would not likely result in a per share
  consideration payable to Xpedite stockholders as high in value as the
  Merger Consideration. The Strategic Alternatives considered by Xpedite were
  those which the Xpedite Board believed would result in liquidity and
  enhanced value for Xpedite's stockholders;
 
    (vii) the Xpedite Board's desire to enable Xpedite's stockholders to
  achieve liquidity with respect to their investment in Xpedite at a fair
  price and the Xpedite Board's conclusion that the sale of Xpedite as a
  whole was the best way to achieve such liquidity in the foreseeable future;
 
    (viii) the fact that Xpedite stockholders will receive Premiere Common
  Stock in exchange for their Xpedite Common Stock, which the Xpedite Board
  believes will provide some flexibility to the Xpedite stockholders who
  might desire to retain Premiere Common Stock after the Merger and also to
  those Xpedite stockholders who might desire to liquidate their investments,
  insofar as the Xpedite Board believes that a liquid market exists for
  Premiere Common Stock; and
 
    (ix) the fact that the Merger Agreement requires the Merger to be
  submitted to the Xpedite stockholders for adoption, which allows for an
  informed vote of the Xpedite stockholders on the merits of the transaction
  without requiring a tender of shares or other potentially coercive
  transaction structure; and the fact that the Merger Agreement provides that
  it may be terminated if such adoption is not received.
 
  In addition to the foregoing, the Xpedite Board considered the detriments of
the Merger to Xpedite and its stockholders, including that (i) at certain
times since Premiere's initial public offering, there has been a substantial
amount of volatility in the market price of the Premiere Common Stock (see
"Summary--Market Prices and Dividends"), (ii) uncertainty as to the timing and
magnitude of business synergies or other benefits to be realized by either
Premiere or Xpedite through the Merger, and (iii) as a result of the
termination of the Prior Merger Agreement, Xpedite was required to pay a
"break-up" fee of $7.5 million to Xpedite Acquisition Corp. and to reimburse
Xpedite Acquisition Corp. for up to $2.0 million of documented expenses
incurred in connection with the Prior Merger Agreement. The Xpedite Board also
considered the fact that, although the process conducted by Merrill Lynch was
conducted over a period of only about five months, in connection with
 
                                      44
<PAGE>
 
such process Merrill Lynch solicited indications of interest in Xpedite from
over 100 parties, including a substantial number of both strategic and
financial investors.
 
  The foregoing discussion of the information and factors discussed by the
Xpedite Board is not meant to be exhaustive but includes all material factors
considered by the Xpedite Board. The Xpedite Board did not quantify or attach
any particular weight to the various factors that it considered in reaching
its determination that the Merger is in the best interests of the Xpedite
stockholders. The Xpedite Board believes the Merger achieves greater liquidity
than that which presently exists for Xpedite's stockholders (in light of the
historically low level of trading volume of the Xpedite Common Stock, relative
to the number of outstanding shares of Xpedite Common Stock and the relatively
high level of trading volume of the Premiere Common Stock) and enhanced value
(in light of the fact that, except during a few isolated periods--including
the period after the MBO Proposal was made, during which the Xpedite Board
believes the market assumed Xpedite would be sold at a price equal to or
greater than that set forth in the MBO Proposal--the Xpedite Common Stock has
historically traded around or below $20 per share).
 
  The Xpedite Board was aware that certain members of Xpedite management and
the Xpedite Board may be deemed to have certain interests in the Merger that
are in addition to their interests as Xpedite stockholders generally and
considered these interests in approving the Merger. Such interests did not
weigh either in favor of or against approving the Merger. See "--Interests of
Certain Persons in the Merger."
 
  If the holders of Xpedite Common Stock do not adopt the Merger Agreement, or
if the Merger is not consummated for any other reason, the Xpedite Board
expects to continue to operate Xpedite as an ongoing business as the Xpedite
Board does not believe that liquidating Xpedite was a reasonable Strategic
Alternative. In accordance with such view, Xpedite did not consider the
liquidation value per share in determining whether the price offered was fair
because it was the Xpedite Board's belief that the value that Xpedite would
obtain through liquidating its assets would be materially lower than the value
obtainable through selling Xpedite as an ongoing business.
 
  The Xpedite Board has determined that the Merger Agreement and the Merger
are advisable and fair to and in the best interests of Xpedite and its
stockholders and have unanimously approved and adopted the Merger Agreement
and the Merger. Accordingly, the Xpedite Board unanimously recommends that
Xpedite stockholders vote "FOR" adoption of the Merger Agreement.
 
 Premiere
 
  In reaching its conclusion to approve the Merger and transactions
contemplated thereby, the Premiere Board of Directors consulted with
Premiere's management and its financial, accounting, and legal advisors. The
Premiere Board of Directors considered the Merger and the transactions
contemplated thereby primarily at its meeting on November 3, 1997 (and again
on November 11, 1997) and considered various factors, including the following:
 
  Premiere Growth Strategy. Premiere's Board of Directors considered
Premiere's strategy of complementing internal growth with acquisitions that
strengthen Premiere's service offerings, customer base, distribution channels,
network and platform capabilities, geographic reach and management depth. The
Premiere Board concluded that the Merger is a major step in implementing and
accelerating that strategy for long-term growth and enhanced stockholders'
value. As a leading provider of enhanced electronic document distribution
services, Xpedite provides an important and previously underdeveloped line of
enhanced communications services that Premiere believes are important to its
market strategy. Following the Merger, the combined company will offer a
comprehensive suite of enhanced communication services including mobile
personal communications, enhanced document distribution, voice messaging, and
e-mail and Internet related services, both as separate service offerings and,
through Premiere's intelligent network, on a bundled and integrated basis.
 
  In addition to the complementary service offerings, the Premiere Board
reviewed information concerning Xpedite's large and diverse customer base and
its domestic and international solution-oriented direct sales force.
 
                                      45
<PAGE>
 
The Premiere Board concluded that the combination of Premiere and Xpedite
provides attractive opportunities for cross marketing other Premiere services
and extends Premiere's reach into significant new international markets. The
Premiere Board also concluded that Xpedite's extensive international network,
when integrated with the international frame relay system acquired in the
Voice-Tel Acquisitions, will create a powerful worldwide voice and data
message transmission engine that offers significant cost saving opportunities
for the combined company. As a result of the Merger, Premiere will have a
direct sales force of approximately 600 sales employees in North America,
Europe, Asia and Australia/New Zealand and a private network with
approximately 300 POPs in 29 countries on six continents.
 
  The Premiere Board also reviewed management's assessment of Xpedite's senior
management and concluded that Xpedite's culture of customer driven
communications solutions would integrate well into Premiere's culture. In this
regard, the Premiere Board also noted the employment agreements in place with
senior management of Xpedite, the options held by such persons, the proposed
options and stay bonuses to be granted and made available to such persons, and
the agreement that Roy Andersen would be added to the Premiere Board following
the Merger.
 
  Potential Cost and Operating Synergies. The Premiere Board has concluded
that the combination of Premiere and Xpedite presents significant
opportunities for cost savings and operating efficiencies. Premiere's
management estimates that annual operating cost savings of approximately $20.5
million pre-tax are achievable by the year 2000. In addition, the combination
of the Xpedite and Premiere networks will reduce capital expenditures required
for operating and expanding stand-alone networks. There can, however, be no
assurance that any specific level of cost savings or other synergies will be
achieved or that such cost savings or other synergies will be achieved within
the time period contemplated.
 
  Set forth below are the cost saving synergies estimated by Premiere to be
achievable as a result of the Merger.

  The information contained in this section was not prepared with a view
toward compliance with published guidelines of the SEC or the American
Institute of Certified Public Accountants regarding forward-looking
information or generally accepted accounting principles and was not examined,
reviewed or complied by independent public accountants and, accordingly, the
independent public accountants do not express an opinion or any other form of
assurance with respect thereto. The estimates of achievable cost synergies
("synergies") were based upon a variety of estimates and assumptions. The
estimates and assumptions underlying the synergies involved judgments with
respect to, among other things, future economic, competitive, regulatory and
financial market conditions and future business decisions which may not be
realized and are inherently subject to significant business, economic,
competitive and regulatory uncertainties, all of which are difficult to
predict and many of which are beyond the control of Premiere and Xpedite and
will be beyond the control of the combined companies. There can be no
assurances that the synergies will be realized, and actual results may vary
materially from those shown. Additionally, the synergies do not reflect
revised prospects for Premiere, Xpedite or the combined companies' businesses,
changes in general business and economic conditions, or any other transaction
or event that has occurred or that may occur and that was not anticipated at
the time such information was prepared. None of the synergies were intended to
be a forecast of profits by Premiere, Xpedite and the combined companies or
any of their directors, and in deciding whether or not to approve the Merger,
shareholders of Premiere and Xpedite should not put undue reliance on any such
synergies. Neither Premiere nor Xpedite have updated or supplemented this
information or intend to do so. See "Forward-Looking Statements" and "Risk
Factors."

  Certain Financial and Related Information. The Premiere Board received
certain additional information, including, but not limited to, (a) a financial
review relating to historical financial performance, financial projections,
service offerings and expenses, and (b) a merger analysis including, but not
limited to, respective stock performance, comparative financial data, pro
forma financial analyses, and comparable merger and acquisition transactions.
The information was presented by Premiere's management, together with
representatives of Premiere's financial advisors, as part of Premiere's due
diligence process. See "--Opinions of Financial Advisors; Premiere."
   
  Certain Nonfinancial Information. Drafts of the principle documents relating
to the Merger were distributed to the Premiere Board at its November 3, 1997
meeting and summarized by Premiere's management and legal advisors. These
included (a) the then current draft of Merger Agreement, and related exhibits
and schedules, and (b) the XSL Purchase Agreement. The Premiere Board of
Directors also considered the management structure, options for Premiere
Common Stock to be granted to members of Xpedite's management team and the
addition of Mr. Andersen to the Premiere Board of Directors. Additionally, the
Premiere Board considered the effect of the issuance of Premiere Common Stock
in the Merger and the grant of options for Premiere Common Stock to members of
Xpedite's management team. It also considered the termination fees and
expenses of up to $9,500,000 payable to Xpedite Acquisition Corp. under
certain circumstances upon the event of the termination of the Prior Merger
Agreement. The Premiere Board was advised of the provision for a termination
fee and expenses of up to $10,500,000 to be paid to Premiere if the Merger is
not consummated under certain circumstances. See "--Expenses and Termination
Fees."     
 
  Advice of Financial Advisor and Fairness Opinion. Prudential Securities
delivered an oral opinion to the Premiere Board on November 11, 1997, to the
effect that, as of such date, the consideration to be paid by Premiere in the
Merger was fair to Premiere from a financial point of view. Prudential
Securities subsequently delivered its written opinion dated November 12, 1997,
to the effect that, as of such date, the consideration to be paid by Premiere
in the Merger was fair, from a financial point of view, to Premiere. See "--
Opinions of Financial Advisors; Premiere."
 
  Regulatory Approvals. The Premiere Board of Directors considered the
likelihood of obtaining regulatory approvals that would be required with
respect to the Merger, including approvals required under the HSR Act and
approval of the European Union. See "--Regulatory Approvals."
 
  The foregoing discussion of the information and factors considered by the
Premiere Board of Directors is not intended to be exhaustive but is believed
to include all material factors considered by the Premiere Board of Directors.
In view of the variety of factors considered in connection with its evaluation
of the proposed Merger, the Premiere Board of Directors did not find it
practicable to and did not quantify or otherwise assign relative weights to
the specific factors considered in reaching its determination. In addition,
individual members of the Premiere Board of Directors may have given different
weights to different factors.
 
  THE PREMIERE BOARD OF DIRECTORS HAS UNANIMOUSLY CONCLUDED THAT THE MERGER IS
IN THE BEST INTERESTS OF PREMIERE AND ITS STOCKHOLDERS AND UNANIMOUSLY
RECOMMENDS THAT PREMIERE STOCKHOLDERS VOTE "FOR" THE ISSUANCE OF PREMIERE
COMMON STOCK PURSUANT TO THE MERGER AGREEMENT.
 
OPINIONS OF FINANCIAL ADVISORS
 
 Xpedite
   
  Xpedite retained Merrill Lynch to act as its exclusive financial advisor in
connection with its evaluation of Strategic Alternatives. On November 13,
1997, Merrill Lynch rendered to the Xpedite Board its written opinion (the
"Merrill Lynch Opinion") that, as of such date and based upon and subject to
the factors and assumptions set forth therein, the Merger Consideration was
fair, from a financial point of view, to the holders of Xpedite Common Stock.
For purposes of rendering the Merrill Lynch Opinion, Merrill Lynch assumed
that Xpedite     
 
                                      47
<PAGE>
 
   
would not consummate the Merger under circumstances where the Threshold Price
Termination Right is exercisable and therefore such opinion would be
inapplicable under such circumstances. See "The Merger--Termination and
Possible Exchange Ratio Increase."     
 
  The full text of the Merrill Lynch Opinion, which sets forth the assumptions
made, matters considered, and qualifications and limitations on the review
undertaken by Merrill Lynch, is attached as Annex B to this Joint Proxy
Statement/Prospectus and is incorporated herein by reference. The summary of
the Merrill Lynch Opinion set forth in this Joint Proxy Statement/Prospectus
is qualified in its entirety by reference to the full text of such opinion.
Stockholders of Xpedite are urged to read such opinion in its entirety. The
Merrill Lynch Opinion was provided to the Xpedite Board for its information
and is directed only to the fairness from a financial point of view of the
Merger Consideration to the holders of Xpedite Common Stock, does not address
the merits of the underlying decision by Xpedite to engage in the Merger and
does not constitute a recommendation to any Xpedite stockholder as to how such
stockholder should vote on the proposed Merger or any matter related thereto.
 
  The Merger Consideration was determined through negotiations between
Premiere and Xpedite and was approved by the Xpedite Board. Merrill Lynch
provided advice to Xpedite during the course of such negotiations.
 
  The summary set forth below does not purport to be a complete description of
the analyses underlying the Merrill Lynch Opinion or the presentation made by
Merrill Lynch to the Xpedite Board. The preparation of a fairness opinion is a
complex analytic process involving various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
those methods to the particular circumstances and, therefore, such an opinion
is not readily susceptible to partial analysis or summary description. In
arriving at its opinion, Merrill Lynch did not attribute any particular weight
to any analysis or factor considered by it, but rather made qualitative
judgments as to the significance and relevance of each analysis and factor.
Accordingly, Merrill Lynch believes that its analyses must be considered as a
whole and that selecting portions of its analyses, without considering all
analyses, would create an incomplete view of the process underlying its
opinion.
 
  In performing its analyses, numerous assumptions were made with respect to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Merrill
Lynch and Xpedite. Any estimates contained in the analyses performed by
Merrill Lynch are not necessarily indicative of actual values or future
results, which may be significantly more or less favorable than suggested by
such analyses. Additionally, estimates of the value of businesses or
securities do not purport to be appraisals or to reflect the prices at which
such businesses or securities might actually be sold. Accordingly, such
analyses and estimates are inherently subject to substantial uncertainty. In
addition, as described above, the Merrill Lynch Opinion was among several
factors taken into consideration by the Xpedite Board in making its
determination to approve the Merger Agreement and the Merger. Consequently,
the Merrill Lynch analyses described below should not be viewed as
determinative of the decision of the Xpedite Board with respect to the
fairness of the Merger Consideration.
 
  Merrill Lynch expresses no opinion as to the relative value of the Merger
Consideration as compared to the consideration that may be proposed to be
delivered pursuant to any other transaction proposal which Xpedite has
received or may receive. In addition, Merrill Lynch expressed no opinion as to
the prices at which Xpedite Common Stock, Premiere Common Stock or any other
securities of Xpedite or Premiere would trade following the announcement or
consummation of the Merger. In rendering its opinion, Merrill Lynch evaluated
Xpedite on a pro forma basis after giving effect to the XSL Acquisition.
However, the Merrill Lynch Opinion does not constitute an opinion on the
fairness or any other aspect of the XSL Acquisition itself. Furthermore, in
rendering its opinion, due to the speculative nature of the existing put-call
arrangements relating to XSL, Xpedite Germany and Xpedite Systems S.A. (the
"European Put-Call Arrangements"), Merrill Lynch evaluated Xpedite without
regard to any aspect of the European Put-Call Arrangements. Merrill Lynch
rendered its opinion as if the XSL Acquisition had been consummated and the
European Put-Call Arrangements were not contemplated or consummated, and the
Merrill Lynch Opinion does not take into consideration the potential financial
 
                                      48
<PAGE>
 
ramifications to Xpedite of the European Put-Call Arrangements, including any
element of value associated therewith.
 
  In arriving at its opinion, Merrill Lynch, among other things, (i) reviewed
certain publicly available business and financial information relating to
Xpedite and Premiere which Merrill Lynch deemed to be relevant, (ii) reviewed
certain information, including financial forecasts, relating to the business,
earnings, cash flow, assets, liabilities and prospects of Xpedite (including
after giving effect to the XSL Acquisition) and Premiere (with respect to
Premiere such financial forecast information was limited to fiscal years 1997
and 1998), furnished to Merrill Lynch by Xpedite and Premiere, respectively,
(iii) reviewed certain information, including financial forecasts, relating to
the business, earnings, cash flow, assets, liabilities and prospects of XSL,
furnished to Merrill Lynch by Xpedite and XSL, (iv) conducted discussions with
members of senior management and representatives of Xpedite and Premiere
concerning the matters described in clauses (i) and (ii) above as well as
their respective business and prospects before and after giving effect to the
Merger; (v) conducted discussions with members of senior management and
representatives of Xpedite and XSL concerning the matters described in clause
(iii) above, (vi) reviewed the market prices and valuation multiples for
Xpedite Common Stock and Premiere Common Stock and compared them with those of
certain publicly traded companies which Merrill Lynch deemed to be relevant,
(vii) reviewed the results of operations of Xpedite (including after giving
effect to the XSL Acquisition) and compared them with those of certain
publicly traded companies which Merrill Lynch deemed to be relevant, (viii)
compared the proposed financial terms of the Merger with the financial terms
of certain other transactions which Merrill Lynch deemed to be relevant, (ix)
participated in certain discussions and negotiations among representatives of
Xpedite and Premiere and their financial and legal advisers, (x) reviewed the
potential pro forma impact of the Merger, (xi) reviewed a recent draft of the
Merger Agreement and (xii) reviewed such other financial studies and analyses
and took into account such other matters as Merrill Lynch deemed necessary,
including Merrill Lynch's assessment of general economic, market and monetary
conditions.
 
  In preparing its opinion, Merrill Lynch assumed and relied on the accuracy
and completeness of all information supplied or otherwise made available to
Merrill Lynch, discussed with or reviewed by or for Merrill Lynch, or publicly
available, and Merrill Lynch did not assume any responsibility for
independently verifying such information and Merrill Lynch has not undertaken
an independent evaluation or appraisal of any of the assets or liabilities of
Xpedite (including after giving effect to the XSL Acquisition) or Premiere or
been furnished with any such evaluation or appraisal. In addition, Merrill
Lynch did not assume any obligation to conduct any physical inspection of the
properties or facilities of Xpedite (including after giving effect to the XSL
Acquisition) or Premiere. With respect to the financial forecast information
furnished to or discussed with Merrill Lynch by Xpedite, XSL or Premiere,
Merrill Lynch assumed that they have been reasonably prepared and reflect the
best currently available estimates and judgment of Xpedite's, the XSL's or
Premiere's management as to the expected future financial performance of
Xpedite (including after giving effect to the XSL Acquisition) or Premiere, as
the case may be. Merrill Lynch further assumed that the Merger will be
accounted for as a pooling of interests under generally accepted accounting
principles and that it will qualify as a tax-free reorganization for U.S.
federal income tax purposes. Merrill Lynch also assumed that the final form of
the Merger Agreement would be substantially similar to the last draft it
reviewed. The Merrill Lynch Opinion is necessarily based upon market, economic
and other conditions as they existed on, and could be evaluated as of, the
date of such opinion. Merrill Lynch assumed that in the course of obtaining
the necessary regulatory or other consents or approvals (contractual or
otherwise) for the Merger, no restrictions, including any divestiture
requirements or amendments or modifications, will be imposed that will have a
material adverse effect on the contemplated benefits of the Merger. For
purposes of rendering this opinion, Merrill Lynch also assumed that Xpedite
will not consummate the Merger under circumstances where the Threshold Price
Termination Right is exercisable.
 
  The following is a brief summary of the material analyses presented by
Merrill Lynch to the Xpedite Board in connection with the rendering of the
Merrill Lynch Opinion.
 
 Valuation of Xpedite
 
  Comparable Public Company Analysis. Merrill Lynch concluded that there were
no publicly-traded enhanced fax services providers comparable to Xpedite other
than FaxSav, Inc., which, due to its $22.4 million
 
                                      49
<PAGE>
 
market value, could not be considered a good comparable company. As a proxy
for publicly traded companies comparable to Xpedite, Merrill Lynch compared
certain financial and operating information and multiples for Xpedite with
corresponding financial and operating information and multiples for a group of
publicly-traded long-distance resellers which exhibited properties similar to
Xpedite as value-added resellers of communication services. These companies
included EXCEL Communications, Inc., LCI International, Inc. and Tel-Save
Holdings, Inc. (collectively, the "Xpedite Comparables"). Based on information
from certain publicly available research reports and analysts' forecasts,
Merrill Lynch compared the (i) outstanding public float for the Xpedite
Comparables, which ranged from $602 million to $1,835 million, to Xpedite's
public float of $91 million, (ii) last 12 months ("LTM") earnings before
interest, taxes, depreciation and amortization ("EBITDA") margin for the
Xpedite Comparables, which ranged from 16.7% to 18.9%, to Xpedite's LTM EBITDA
margin of 21.3% (calculated on a stand-alone basis before giving effect to the
XSL Acquisition), (iii) five-year estimated earnings growth rate for the
Xpedite Comparables, which ranged from 12% to 32%, to Xpedite's five-year
estimated earnings growth rate of 22% (calculated on a stand-alone basis
before giving effect to the XSL Acquisition), (iv) 1998 estimated EBITDA
trading multiples for the Xpedite Comparables, which ranged from 4.9X to 7.4X,
to Xpedite's 1998 estimated EBITDA trading multiple of 5.4X (calculated on a
stand-alone basis before giving effect to the XSL Acquisition), (v) 1997
estimated net income trading multiples for the Xpedite Comparables, which
ranged from 19.1X to 39.5X, to Xpedite's 1997 estimated net income trading
multiple of 15.3X (calculated on a stand-alone basis before giving effect to
the XSL Acquisition) and (vi) 1998 estimated net income trading multiples for
the Xpedite Comparables, which ranged from 13.9X to 20.4X, to Xpedite's 1998
estimated net income trading multiple of 10.9X (calculated on a stand-alone
basis before giving effect to the XSL Acquisition). Merrill Lynch also
compared historical multiples of one-year forward-looking earnings per share
for the Xpedite Comparables, which averaged 28.4X, to Xpedite's historical
multiples of one year forward looking earnings per share of 16.5X (calculated
on a stand-alone basis before giving effect to the XSL Acquisition).
 
  Merrill Lynch also compared the ratio of the 1998 estimated price to
earnings ratio to the 5-year growth rate (the "P/E to Growth Rate Ratio") for
the Xpedite Comparables (based on certain information provided by IBES), which
ranged from 64% to 116%, to Xpedite's P/E to Growth Rate Ratio of 50%. Merrill
Lynch noted that the Xpedite Comparables typically trade at a multiple of
forward earnings representing a discount to their expected long-term earnings
growth rate. Due to a number of qualitative considerations regarding Xpedite
and the market for enhanced fax services, Merrill Lynch determined that it was
reasonable to expect that Xpedite would trade at a greater discount to its
expected five-year earnings growth rate than the Xpedite Comparables.
 
  Merrill Lynch calculated a range of implied per share values for the Xpedite
Common Stock based on 1998 estimated pro forma earnings per share of $2.15
(giving effect to the XSL Acquisition), a range of long-term compounded annual
"core" earnings growth rates representing growth in earnings before interest
and taxes ("Compounded Annual Core Earnings Growth Rates") of 15.0% to 25.0%
and a range of P/E to Growth Rate Ratios of 45% to 65%. The range of
Compounded Annual Core Earnings Growth Rates was determined by Merrill Lynch
from its review of the pro forma projected long-term compounded annual "core"
earnings growth rates resulting from the XSL Acquisition which were based on
the Scenario A Pro Forma Projections, the Scenario B Pro Forma Projections and
the Scenario C Pro Forma Projections (all as defined below under "--Discounted
Cash Flow Analysis"). Merrill Lynch also calculated a range of implied price
to earnings multiples ("P/E Multiples") for the Xpedite Common Stock based on
these parameters. The summary reference range of per share values for Xpedite
Common Stock resulting from the analysis ranged from $20.50 to $26.75
(representing P/E Multiples of 9.5X to 12.5X 1998 estimated earnings per
share, pro forma for the XSL Acquisition, of $2.15).
 
  Due to the lack of comparable publicly-traded enhanced fax services
providers, Merrill Lynch compared Xpedite with publicly-traded resellers of
long-distance communications services in its analysis. An analysis of the
results of such a comparison is not purely mathematical; rather, it involves
complex considerations and judgments concerning differences in historical and
projected financial and operating characteristics of the comparable companies
and other factors that could affect the value of such companies and Xpedite,
including the differences between the enhanced fax services industry and the
long-distance resellers industry.
 
                                      50

  Comparable Acquisition Transaction Analysis. Merrill Lynch reviewed certain
publicly available information regarding 15 selected long-distance
communications and enhanced fax services related acquisitions and calculated
trailing 12-month EBITDA multiples, earnings before interest and taxes
("EBIT") multiples and revenue multiples for such acquisitions. Among the 15
selected acquisitions, the analysis indicated transaction value as a multiple
of (i) trailing 12-month EBITDA ranging from 6.8X to 24.3X with a mean of
13.0X, (ii) trailing 12-month EBIT ranging from 6.2X to 48.4X with a mean of
17.8X and (iii) trailing 12-month revenues ranging from 0.60X to 2.87X with a
mean of 1.65X. Based on its comparison of such multiples, Merrill Lynch
calculated a summary reference range of implied per share values of the
Xpedite Common Stock of $24.50 to $32.00.
 
  No company utilized in the comparable transaction analysis was identical to
Xpedite. Accordingly, an analysis of the results of this comparison is not
purely mathematical; rather, it involves complex considerations and judgments
primarily concerning differences in historical and projected financial,
operating and trading characteristics of the companies involved in such other
transactions and the circumstances surrounding such transactions.
 
  Discounted Cash Flow Analysis. Using a discounted cash flow methodology,
Merrill Lynch calculated a range of implied per share values for the Xpedite
Common Stock based on (i) a range of terminal EBITDA multiples of 5.5X to
7.5X, (ii) a range of cash flow perpetuity rates of 4.0% to 6.0% and (iii) a
range of discount rates of 14% to 16%. Based on Xpedite's "base-case" and
XSL's "management case" projections ("Scenario A Pro Forma Projections"),
Merrill Lynch calculated a summary reference range of implied per share values
for the Xpedite Common Stock of $25.25 to $39.75. Based on Xpedite's "base-
case" and XSL's "more conservative case projections" ("Scenario B Pro Forma
Projections"), Merrill Lynch calculated a summary reference range of implied
per share values for the Xpedite Common Stock of $23.25 to $36.75. Based on
Xpedite's "more conservative case" and XSL's "more conservative case"
projections ("Scenario C Pro Forma Projections"), Merrill Lynch calculated a
summary reference range of implied per share values for the Xpedite Common
Stock of $17.00 to $27.75.
 
  LBO Feasibility Analysis. Merrill Lynch calculated certain pro forma credit
statistics for Xpedite based on the pro forma capital structure for the
Company and an assumed $25.00 offer price (representing the mid-point of the
reference range set forth below). Based on pro forma financial results (giving
effect to the XSL Acquisition) for the last 12 months ending September 30,
1997 and Xpedite pro forma management estimates (giving effect to the XSL
Acquisition) for the last twelve months ending December 31, 1997, Merrill
Lynch calculated (i) EBITDA as a multiple of Total Interest of 1.9X and 2.0X,
respectively, (ii) EBITDA minus capital expenditures as a multiple of total
interest of 1.5X and 1.6X, respectively, (iii) Senior Debt as a multiple of
EBITDA of 2.39X and 2.28X, respectively and (iv) total debt as a multiple of
EBITDA of 5.57X and 5.32X, respectively.
 
  Merrill Lynch also calculated ranges of implied five-year equity returns for
Xpedite Common Stock based on Scenario A Pro Forma Projections, Scenario B Pro
Forma Projections and Scenario C Pro Forma Projections of (i) 30% to 37%, 26%
to 34% and 8% to 18%, respectively, based on a terminal EBITDA multiple of
5.5X and (ii) 43% to 50%, 40% to 47% and 26% to 34%, respectively, based on a
terminal EBITDA multiple of 7.5X.
 
  Based on its analysis of leveraged buyout feasibility utilizing such credit
statistics and five-year equity returns, Merrill Lynch calculated a summary
reference range implied per share values of the Xpedite Common Stock of $23.00
to $27.00.
 
  Historical Trading Observations. Merrill Lynch observed the historical stock
price for Xpedite Common Stock from January 1, 1995 to October 30, 1997.
Merrill Lynch calculated that the Merger Consideration to be paid to the
holders of Xpedite Common Stock (assuming that Premiere Common Stock trades in
a range that allows the holders of Xpedite Common Stock to receive $34.00 in
value per share) represented a premium of (i) 126.7% over the February 14,
1994 IPO price of $15.00, (ii) 66.2% over the 12-month average historical
 
                                      51
<PAGE>
 
closing price of $20.46, (iii) 46.2% over the Cash Price of $23.25, (iv) 82.5%
over the closing price on July 3, 1997 (the last trading day prior to the
announcement of the Final MBO Offer) of $18.63, (v) 56.3% over the closing
price on October 30, 1997 (the last trading day prior to public disclosure of
Premiere's initial indication of interest) of $21.75 and (vi) 22.5% over the
all-time high closing price on July 3, 1996 of $27.75.
 
 Valuation of Premiere Technologies, Inc.
 
  Comparable Public Company Analysis. Merrill Lynch concluded that there were
no publicly traded companies that provided network-based, unified messaging
services and mobile communications services comparable to Premiere. As a proxy
for publicly traded companies comparable to Premiere, Merrill Lynch compared
certain financial and operating information and multiples for Premiere with
corresponding financial and operating information and multiples for a group of
publicly traded premise-based, unified messaging technology companies and a
group of calling card and electronic transaction companies. The premise-based,
unified messaging companies exhibited properties similar to Premiere in that
they provide similar services to a similar customer base. The calling card and
electronic services companies exhibited properties similar to Premiere in that
they provide services through similar network platforms, generate revenues per
transaction and rely on growth of a similar, technologically savvy consumer
base. The premise-based, unified messaging companies included Comverse
Technology, Centigram Communications, Applied Voice Technology and Active
Voice Corporation (collectively, the "Messaging Comparables"). The calling
card and electronic transaction companies included SmarTalk, Executive
Telecard, E*Trade Group and Transaction Network Services (collectively, the
"Mobile Communications Comparables" and, together with the Messaging
Comparables, the "Premiere Comparable Companies").
 
  Merrill Lynch analyzed the Premiere Comparable Companies and derived a range
of 1998 estimated earnings per share multiples of 24.5X to 35.0X. Based on
Premiere's 1998 estimated earnings per share of $1.20 (based on First Call),
Merrill Lynch calculated a summary reference range of per share values for
Premiere Common Stock of $29.50 to $42.00.
 
  Due to the lack of comparable publicly traded, network-based unified
messaging service companies, Merrill Lynch compared Premiere with publicly
traded, premise-based, unified messaging technology and calling card and
electronic transaction companies in its analysis. An analysis of the results
of such a comparison is not purely mathematical; rather, it involves complex
considerations and judgments concerning differences in historical and
projected financial and operating characteristics of the comparable companies
and other factors that could affect the value of such companies and Premiere,
including the differences between the network-based, unified messaging
services industry and the premise-based, unified messaging technology, calling
card and electronic transaction industries.
 
  52-Week High-Low. Merrill Lynch observed that the 52-week high and low stock
price for Premiere Common Stock was $38.50 and $16.50, respectively.
 
  Segment Valuation. Merrill Lynch analyzed the implicit values of Premiere's
business segments, voice messaging and mobile communications, based on certain
financial and operating information and multiples of the Messaging Comparables
and the Mobile Communications Comparables, respectively. Based on its
valuations of Premiere's voice messaging and mobile communications segments,
Merrill Lynch calculated a summary reference range of per share values for
Premiere Common Stock of $19.25 to $34.75.
 
 Pro Forma Combination Analysis
 
  Based on 1998 estimates provided by Premiere management and Scenario B Pro
Forma Projections provided by Xpedite management, Merrill Lynch analyzed
certain pro forma effects of the Merger. Merrill Lynch's pro forma combination
analysis (i) assumed that the Merger would be accounted for as a pooling of
interests under generally accepted accounting principles and (ii) did not
assume any synergies from the Merger.
 
 
                                      52
<PAGE>
 
  Pro Forma Earnings Per Share and Five-Year Growth Rate Analysis. Merrill
Lynch analyzed the pro forma impact of the Merger on Premiere's 1998 estimated
earnings per share and Premiere's First Call five-year growth rate based on a
range of exchange ratios resulting from Premiere share prices of $27.20 to
$39.20. This analysis indicated that the Merger would (i) be accretive to
Premiere's pro forma 1998 earnings per share and (ii) produce a range of pro
forma three-year growth rates of 42.5% to 42.8%, as compared to Premiere's
five-year growth rate of 47.0%.
 
  Contribution Analysis. Based on projections provided by Premiere's
management and the Scenario B Pro Forma Projections provided by Xpedite's
management, Merrill Lynch reviewed the relative contribution in terms of
estimated 1998 pre-tax income, estimated 1998 net income and estimated 1998
after-tax cash flow of the pro forma combined company. This analysis showed
that Xpedite stockholders would own approximately 20.5% of the outstanding
shares of the pro forma combined company, on a fully diluted basis (assuming
conversion of Premiere's Convertible Subordinated Notes due 2004 and based on
a stock price of $29.25 for Premiere). Merrill Lynch calculated that Xpedite's
implied contribution to the pro forma combined company for calendar year 1998
was 26.6% of pre-tax income, 26.0% of net income and 29.7% of after-tax cash
flow (assuming conversion of Premiere's Convertible Subordinated Notes due
2004 and based on a stock price of $29.25 for Premiere).
 
  Pursuant to a letter agreement between Xpedite and Merrill Lynch, Xpedite
agreed to pay Merrill Lynch (i) a fee of $100,000 payable on the date of the
letter agreement, (ii) a fee in the amount of $750,000 payable upon the
closing of the XSL Acquisition or certain other business combinations
involving Xpedite or its affiliates and XSL, (iii) a fee in the amount of
$500,000 payable upon the consummation of a recapitalization transaction,
provided that such a fee shall be reduced by any fee paid pursuant to clause
(i), and (iv) an additional fee in an amount equal to 0.75% of the aggregate
purchase price paid in the Merger or certain other business combinations
involving Xpedite, payable upon the closing of the Merger or such other
business combination, provided that any fee paid pursuant to this clause (iv)
will be reduced by (A) the portion of any fee paid to Merrill Lynch pursuant
to clause (ii) in excess of $500,000 and (B) any fee paid pursuant to clause
(iii); provided, however, that if no fee has been paid pursuant to clause
(iii), then the fee paid pursuant to clause (i) in lieu thereof. Pursuant to
such letter agreement, Xpedite also agreed to reimburse Merrill Lynch for its
reasonable out-of-pocket expenses, including certain reasonable fees and
disbursements of its legal counsel. Additionally, Xpedite agreed to indemnify
Merrill Lynch and certain related persons for certain liabilities related to
or arising out of its engagement, including liabilities under the federal
securities laws.
 
  Xpedite retained Merrill Lynch based upon Merrill Lynch's experience and
expertise. Merrill Lynch is an internationally recognized investment banking
and advisory firm. Merrill Lynch, as part of its investment banking business,
is continuously engaged in the valuation of businesses and securities in
connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted

  Merrill Lynch may provide financial advisory and financing services to the
surviving corporation in the Merger and/or its affiliates and may receive fees
for the rendering of such services. In the ordinary course of its business,
Merrill Lynch and its affiliates may actively trade the debt and equity
securities of Xpedite and Premiere for their own account and for the accounts
of customers and, may at any time hold a long or short position in such
securities.
 
 Premiere
 
  On November 3, 1997, Prudential Securities orally advised the Premiere Board
of Directors that, as of such date and assuming a stipulated range of purchase
prices between $27.00 and $35.00 per share for Xpedite paid in shares of
Premiere Common Stock, Prudential Securities was of the view that such
consideration to be paid by Premiere in the Merger would be fair, from a
financial point of view, to Premiere. Prudential Securities made a
presentation of the financial analyses underlying its oral advice at a meeting
of the Premiere Board of Directors on November 3, 1997. All of the members of
the Premiere Board of Directors were present (one participating via
teleconference) and had an opportunity to ask questions regarding Prudential
Securities' presentation. On
 
                                      53
<PAGE>
 
November 11, 1997, Prudential Securities delivered its oral opinion at a
telephonic meeting of the Premiere Board of Directors to the effect that, as
of such date, the consideration to be paid by Premiere in the Merger was fair,
from a financial point of view, to Premiere and delivered its written opinion
(the "Prudential Securities Opinion") to such effect on November 12, 1997.
 
  In requesting the Prudential Securities Opinion, the Premiere Board of
Directors did not give any special instructions to Prudential Securities or
impose any limitation upon the scope of the investigation that Prudential
Securities deemed necessary to enable it to deliver the Prudential Securities
Opinion. The amount of the Merger Consideration to be paid by Premiere was
arrived at through arms-length negotiations between Premiere and Xpedite. A
copy of the Prudential Securities Opinion, which sets forth the assumptions
made, matters considered and limits on the review undertaken, is attached to
this Joint Proxy Statement/Prospectus as Annex C and is incorporated herein by
reference. The summary of the Prudential Securities Opinion set forth below is
qualified in its entirety by reference to the full text of the Prudential
Securities Opinion. The Premiere stockholders are urged to read the Prudential
Securities Opinion in its entirety.
 
  THE PRUDENTIAL SECURITIES OPINION IS DIRECTED ONLY TO THE FAIRNESS, FROM A
FINANCIAL POINT OF VIEW, TO PREMIERE OF THE CONSIDERATION TO BE PAID BY
PREMIERE IN THE MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY
STOCKHOLDER OF PREMIERE AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE PREMIERE
SPECIAL MEETING OR AS TO ANY OTHER ACTION SUCH STOCKHOLDER SHOULD TAKE
REGARDING THE MERGER.
 
  In conducting its analysis and arriving at the Prudential Securities
Opinion, Prudential Securities reviewed such information and considered such
financial and other factors as Prudential Securities deemed relevant under the
circumstances, including: (i) a draft dated November 12, 1997 of the Merger
Agreement; (ii) certain publicly-available information relating to Xpedite

with the Securities and Exchange Commission on October 31, 1997, (c) Xpedite's
Current Report on Form 8-K dated August 8, 1997, and (d) Xpedite's Schedule
13E-3 dated September 18, 1997 and Schedule 13E-3/A dated October 31, 1997;
(iii) certain publicly-available historical financial and operating data for
Xpedite including, but not limited to, (a) the Annual Report on Form 10-K for
the fiscal year ended December 31, 1996, (b) the Quarterly Report on Form 10-Q
for the quarter ended June 30, 1997, and (c) Proxy Statements for the Meetings
of Stockholders held on January 10, 1996, October 1, 1996, and May 15, 1997;
(iv) certain publicly-available historical financial and operating data for
Premiere, including, but not limited to, (a) the Annual Report to Stockholders
and Annual Report on Form 10-K for the fiscal year ended December 31, 1996,
(b) the Quarterly Report on Form 10-Q for the quarter ended June 30, 1997, and
(c) the Proxy Statement for the Annual Meeting of Stockholders held on May 15,
1997; (v) certain information relating to Premiere, including projected income
statement data for the fiscal years ending December 31, 1997 and December 31,
1998, prepared by the management of Premiere; (vi) certain information
relating to XSL, including historical financial data for the fiscal years
ended December 31, 1993 through December 31, 1996, and projected financial

2001, prepared by the management of Xpedite and XSL; (vii) certain information
relating to Xpedite, including financial forecasts for the fiscal years ending
December 31, 1997 through December 31, 2001, prepared by the management of
Xpedite; (viii) consolidated historical financial data for Xpedite and XSL for
the fiscal years ending December 31, 1993 through December 31, 1996, and
projected consolidated financial forecasts for the fiscal years ending
December 31, 1997 through December 31, 2001, prepared by the management of
Xpedite; (ix) publicly available financial, operating and stock market data
concerning certain companies engaged in businesses Prudential Securities
deemed comparable to Xpedite or otherwise relevant to Prudential Securities'
inquiry; (x) the financial terms of certain recent transactions Prudential
Securities deemed relevant to Prudential Securities' inquiry; (xi) the
historical stock prices and trading volumes of Premiere Common Stock and
Xpedite Common Stock; and (xii) such other financial studies, analyses and
investigations that Prudential Securities deemed appropriate. Prudential
Securities assumed, with Premiere's consent, that the draft of the Merger
Agreement which Prudential Securities reviewed would conform in all material
respects to that document when in final form.

  Prudential Securities met with the senior management of Premiere, Xpedite
and XSL to discuss (i) the prospects for their respective businesses, (ii)
their estimates of such businesses' future financial performance, (iii) the
financial impact of the Merger on the respective companies, and (iv) such
other matters that Prudential Securities deemed relevant.
 
  In connection with its review and analysis and in arriving at the Prudential
Securities Opinion, Prudential Securities assumed and relied upon the accuracy
and completeness of the financial and other information provided to it by
Premiere, Xpedite and XSL and has not undertaken any independent verification
of such information or any independent valuation or appraisal of any of the
assets or liabilities of Premiere, Xpedite or XSL. With respect to certain
financial forecasts provided to Prudential Securities by Premiere for Premiere
and by Xpedite for Xpedite and XSL, Prudential Securities has assumed that
such information (and the assumptions and bases therefor) represents each
respective management's best currently available estimate as to the future
financial performance of Premiere, Xpedite and XSL. The Prudential Securities
Opinion is predicated on the Merger qualifying (i) as a reorganization within
the meaning of Section 368(a) of the Code, and (ii) for pooling-of-interests
accounting treatment.
 
  The Prudential Securities Opinion does not address nor should it be
construed to address the relative merits of the Merger or alternative business
strategies that may be available to Premiere. In addition, the Prudential
Securities Opinion does not in any manner address the prices at which the
Premiere Common Stock will trade following consummation of the Merger.
 
  In arriving at the Prudential Securities Opinion, Prudential Securities
performed a variety of financial analyses, including those summarized herein.
The summary set forth below of the analyses presented to the Premiere Board of
Directors at the November 3, 1997 meeting does not purport to be a complete
description of the analyses performed. The preparation of a fairness opinion
is a complex process that involves various determinations as to the most
appropriate and relevant methods of financial analyses and the application of
these methods to the particular circumstance and, therefore, such an opinion
is not necessarily susceptible to partial analysis or summary description.
Prudential Securities believes that its analysis must be considered as a whole
and that selecting portions thereof or portions of the factors considered by
it, without considering all analyses and factors, could create an incomplete
view of the evaluation process underlying the Prudential Securities Opinion.
Prudential Securities made numerous assumptions with respect to industry
performance, general business, economic, market and financial conditions and
other matters, many of which are beyond the control of Premiere, Xpedite and
XSL. Any estimates contained in Prudential Securities' analyses are not
necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by such analyses.
Additionally, estimates of the values of businesses and securities do not
purport to be appraisals or necessarily reflect the prices at which businesses
or securities may be sold. Accordingly, such analyses and estimates are
inherently subject to substantial uncertainty. Subject to the foregoing, the
following is a summary of the material financial analyses presented by
Prudential Securities to the Premiere Board of Directors at its meeting on
November 3, 1997.
 
  Comparable Company Analysis. A comparable company analysis was employed by
Prudential Securities to establish implied valuation ranges in comparison to
the unlevered purchase price (defined as purchase price per share multiplied
by Xpedite's fully-diluted shares outstanding plus the $87.0 million
acquisition of XSL, and Xpedite's and XSL's combined net indebtedness) ("UPP")
of $406.6 million to be paid by Premiere in the Merger (which assumed a
purchase price per share of Xpedite Common Stock of $30.00). Prudential
Securities analyzed publicly-available historical and projected financial
results, including multiples of current stock price to latest 12 months
("LTM") earnings per share ("LTM EPS"), and projected calendar year 1998
earnings per share ("1998 EPS"), unlevered market value (defined as current
stock price multiplied by the number of shares outstanding plus net
indebtedness) to LTM revenues, LTM earnings before interest, taxes,
depreciation and amortization ("LTM EBITDA"), to LTM earnings before interest
and taxes ("LTM EBIT") of certain companies considered by Prudential
Securities to be reasonably similar to Xpedite. The companies analyzed
included: Aliant Communications, Inc., EXCEL Communications, Inc., LCI
International, Inc., and Tel-Save Holdings, Inc. (the "Xpedite Comparable
Companies"). All of the trading multiples of the Xpedite Comparable
 
                                      55
<PAGE>
 
Companies were based on closing stock prices on October 31, 1997 (the "October
31st Closing Price") and all of the earnings per share estimates were
published by First Call, an on-line data service available to subscribers
which compiles estimates developed by research analysts. The estimates
published by First Call were not prepared in connection with the Merger or at
the request of Prudential Securities or Premiere.
 
  The Xpedite Comparable Companies were found to have an October 31st Closing
Price estimated to be within a range of 18.2X to 26.7X LTM EPS and 13.5X to
20.1X 1998 EPS, an unlevered market value estimated to be within a range of
1.7X to 3.7X LTM revenues, 7.7X to 10.5X LTM EBITDA, and 11.2X to 15.1X LTM
EBIT. Applying such multiples to Xpedite's LTM revenues, LTM EBITDA, LTM EBIT,
LTM net income and 1998 projected net income, in each case after giving effect
to the XSL Acquisition, resulted in an implied range for UPP to LTM revenues
of $295.3 million to $642.7 million (with a mean of $434.3 million), UPP to
LTM EBITDA of $333.4 million to $454.7 million (with a mean of $415.7
million), UPP to LTM EBIT of $365.1 million to $492.3 million (with a mean of
$417.3 million), UPP (after adjusting for the combined net indebtedness of
Xpedite and XSL) to LTM net income of $359.7 million to $513.6 million (with a
mean of $417.6 million) and UPP (after adjusted for the combined net
indebtedness of Xpedite and XSL) to 1998 projected net income of $328.7
million to $474.5 million (with a mean of $412.6 million).
 
  None of the companies utilized in the above analysis for comparative
purposes is, of course, identical to Xpedite. Accordingly, a complete analysis
of the results of the foregoing calculations cannot be limited to a
quantitative review of such results and involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the Xpedite Comparable Companies and other factors that could affect the
public trading value of the Xpedite Comparable Companies as well as that of
Xpedite.
 
  Comparable Transactions Analysis. Prudential Securities also analyzed the
consideration paid in several recent merger and acquisition transactions
deemed by Prudential Securities to be reasonably similar to the Merger, and
considered the multiple of the purchase price (defined as the purchase price
of the acquired entity's equity) to the acquired entity's LTM net income and
unlevered purchase price (defined as the purchase price plus the acquired
entity's net indebtedness) to the acquired entity's LTM revenues, LTM EBITDA
and LTM EBIT, based upon publicly available information for such transactions.
The transactions considered were the combinations of: (i) ACC Corporation and
Tel-Save Holdings Inc., (ii) Shared Technologies Fairchild Inc. and Tel-Save
Holdings Inc., (iii) Telco Communications Group, Inc. and EXCEL
Communications, Inc., (iv) Teledial America, Inc./ATS Network Communications
and LCI International, Inc., (v) Corporate Telemanagement Group and LCI
International, Inc. (vi) Schneider Communications, Inc. and Frontier
Corporation, (vii) Alascom, Inc. and AT&T Corporation, (viii) American
Sharecom, Inc. and Frontier Corporation, and (ix) Centex Telemanagement, Inc.
and MFS Communications Company, Inc. (the "Comparable Transactions"). The
Comparable Transactions resulted in a range of unlevered purchase price to LTM
revenues of 0.9X to 2.9X, unlevered purchase prices to LTM EBITDA of 8.2X to
24.2X, unlevered purchase price to LTM EBIT of 6.2X to 46.5X and a range of
purchase price to LTM net income of 17.8X to 44.5X. Applying such multiples to
Xpedite's LTM revenues, LTM EBITDA, LTM EBIT and LTM net income, each case
after giving effect to the XSL Acquisition, resulted in an implied range for
UPP to LTM revenue of $159.8 million to $505.5 million (with a mean of $335.2
million), UPP to LTM EBITDA of $355.1 million to $1,047.9 million (with a mean
of $692.8 million), UPP to LTM EBIT of $232.4 million to $1,546.1 million
(with a mean of $783.4 million) and UPP (after adjusting for combined net
indebtedness of Xpedite and XSL) to LTM net income of $352.5 to $836.5 (with a
mean of $609.6 million).
 
  None of the acquired entities utilized in the above analysis for comparative
purposes is, of course, identical to Xpedite. Accordingly, a complete analysis
of the results of the foregoing calculations cannot be limited to a
quantitative review of such results and involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the acquired entities and other factors that could affect the consideration
paid for each of the acquired entities as well as that of Xpedite.
 
  Pro Forma Earnings Per Share. Prudential Securities also analyzed the pro
forma effect of the Merger (after giving effect to the XSL Acquisition) on
Premiere's projected 1998 earnings per share. An analysis of
 
                                      56
<PAGE>
 
anticipated future results based on projections provided by the management of
Premiere for Premiere and by the management of Xpedite for Xpedite and XSL
indicated that the Merger would result in an increase in Premiere's pro forma
1998 earnings per share assuming that no pre-tax synergies would result from
the Merger.
 
  Projected financial and other information concerning Premiere, Xpedite and
XSL and the pro forma impact of the Merger upon the holders of Premiere Common
Stock are not necessarily indicative of future results. All projected
financial information is subject to numerous contingencies, many of which are
beyond the control of management of Premiere, Xpedite and XSL.
 
  Relative Contribution Analysis. Prudential Securities also reviewed the
relative contributions of Premiere and Xpedite (after giving effect to the XSL
Acquisition) to the combined company. The financial and operating information
reviewed in such analysis included LTM Revenues, LTM EBITDA, LTM EBIT, LTM net
income, projected calendar year 1998 ("CY98") revenues, EBITDA and net income.
This analysis showed that, while the Premiere stockholders would own
approximately 83.5% of the outstanding shares of the combined entity on a
fully diluted basis (without giving effect to the conversion of Premiere's
Convertible Subordinated Notes due 2004 and an assumed price of the Premiere
Common Stock of $34.00 per share), Premiere was contributing 48.4% of LTM
revenues, 50.0% of LTM EBITDA, 48.8% of LTM EBIT, 47.6% of LTM net income,
62.3% of CY98 revenues, 67.6% of CY98 EBITDA, and 69.2% of CY98 net income.
 
  Stock Trading History. Prudential Securities also analyzed the history of
the trading prices and volume for the Premiere Common Stock and the Xpedite
Common Stock. Prudential Securities observed that, since the initial public
offering of Premiere Common Stock, the shares of Premiere Common Stock traded
in the range of $15.13 and $49.50 per share. Prudential Securities also
observed that since the initial public offering of the Xpedite Common Stock
that the shares of Xpedite Common Stock traded in the range of $12.75 and
$27.75.
 
  November 11, 1997 Oral Presentation. On November 11, 1997, Prudential
Securities orally advised the Premiere Board of Directors during a telephonic
Board meeting that, as of such date, the consideration to be paid by Premiere
in the Merger was fair, from a financial point of view, to Premiere.
 
  Based on a $34.00 per share purchase price for Xpedite paid in shares of
Premiere Common Stock, Prudential Securities determined that as of such date
the UPP for Xpedite was equal to $446.3 million, which Prudential Securities
observed was within the range of unlevered purchase prices implied by the
comparable company analysis and comparable transaction analysis presented to
the Premiere Board of Directors at its November 3, 1997 meeting. Additionally,
Prudential Securities analyzed the effect of an unlevered purchase price of
$446.3 million on Premiere's projected 1998 earnings per share. Such analysis,
based on projections provided by the management of Premiere for Premiere and
by the management of Xpedite for Xpedite and XSL, indicated that the Merger
(after giving effect to the XSL Acquisition) would result in an increase in
Premiere's pro forma 1998 earnings per share assuming that no pre-tax
synergies would result from the Merger.
 
  Premiere selected Prudential Securities to act as its financial advisor
because it is a nationally recognized investment banking firm engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions and for other purposes and has substantial experience in
transactions similar to the Merger. The engagement letter with Prudential
Securities provides that Premiere will pay Prudential Securities an advisory
fee equal to: (i) a retainer of $75,000, plus (ii) 0.8% of the total
consideration in the Merger (less any amounts received pursuant to (i) above)
upon consummation of the Merger. In addition, the engagement letter with
Prudential Securities provides that Premiere will reimburse Prudential
Securities for its out-of-pocket and incidental expenses including the fees
and expenses of its legal counsel and those of any advisor retained by
Prudential Securities, which fees and expenses of legal counsel and any other
advisor retained by Prudential Securities will not exceed $25,000 in the
aggregate, and will indemnify Prudential Securities and certain related
persons against certain liabilities, including liabilities under securities
laws, arising out of the Merger or its engagement. In the ordinary course of
business, Prudential Securities may actively trade the shares of Premiere
Common Stock and Xpedite Common Stock for its own account and for the accounts
of customers, and accordingly, may at any time hold a long or short position
in such securities. Prudential Securities Incorporated
 
                                      57

provides equity research coverage on Xpedite and acted as lead-manager for the
initial public offering of Xpedite's Common Stock on February 14, 1994 and as
co-manager for an offering of Xpedite's Common Stock on August 15, 1996.
 
MERGER CONSIDERATION
 
  The Merger Agreement provides that, at the Effective Time, each share of
Xpedite Common Stock (excluding shares held by Xpedite in its treasury) will
be converted into the right to receive upon surrender of such holder's Xpedite
Certificates in accordance with the Merger Agreement a number of shares of
Premiere Common Stock equal to the Exchange Ratio (as defined below)
(including cash in lieu of fractional shares, the "Merger Consideration," and
the aggregate of all Merger Consideration to be paid to holders of Xpedite
Common Stock in connection with the Merger is referred to hereinafter as the
"Aggregate Merger Consideration").
 
  The exchange ratio for determining the number of shares of Premiere Common
Stock to be issued in exchange for each share of Xpedite Common Stock (the
"Exchange Ratio") will be determined by dividing $34.00 by the average of the
daily last sale prices for the Premiere Common Stock as reported on Nasdaq for
the 20 consecutive trading days on which Premiere Common Stock is actually
traded as over-the-counter securities ending on the trading day immediately
prior to the date of the Xpedite Special Meeting (as reported in The Wall
Street Journal or, if not reported thereby, any other authoritative source
selected by Premiere and Xpedite) (the "Average Closing Price"), provided
that, except in certain circumstances (see "--Termination and Possible
Exchange Ratio Increase"), the Exchange Ratio shall not be higher than 1.25
(corresponding to the Minimum Average Closing Price) or lower than .867
(corresponding to the Maximum Average Closing Price). All shares converted or
exchanged into the Merger Consideration will no longer be outstanding, will
automatically be canceled and retired, and will cease to exist, and each
Xpedite Certificate thereafter will represent the right to receive, upon the
surrender of such Xpedite Certificate in accordance with the Merger Agreement,
only the applicable Merger Consideration.
 
  THE MERGER CONSIDERATION IS BASED, IN PART, ON THE AVERAGE CLOSING PRICE, ON
WHICH THE MERGER AGREEMENT HAS PLACED THE LIMITS OF THE MINIMUM AVERAGE
CLOSING PRICE AND THE MAXIMUM AVERAGE CLOSING PRICE. THE PREMIERE COMMON STOCK
MAY EXPERIENCE SIGNIFICANT PRICE AND VOLUME FLUCTUATIONS, WHICH MAY CAUSE THE
AVERAGE CLOSING PRICE TO FALL BELOW THE MINIMUM AVERAGE CLOSING PRICE, OR TO
RISE ABOVE THE MAXIMUM AVERAGE CLOSING PRICE, IN WHICH CASE THE DOLLAR VALUE
OF THE PREMIERE COMMON STOCK THAT THE XPEDITE STOCKHOLDERS WILL RECEIVE IN THE
MERGER MAY BE MORE OR LESS THAN THE VALUE OF THE PREMIERE COMMON STOCK AS OF
THE DATE OF EXECUTION OF THE MERGER AGREEMENT, THE DATE HEREOF, THE DATE OF
THE XPEDITE SPECIAL MEETING, THE DATE OF RECEIPT OF SHARES OF PREMIERE COMMON
STOCK BY HOLDERS OF XPEDITE COMMON STOCK, OR THE DATE ON WHICH SUCH SHARES ARE
EVENTUALLY SOLD.
   
  Since the date of the Merger Agreement, the market price of Premiere Common
Stock has been subject to significant fluctuation, with the high and low
closing price therefor ranging from $28 11/16 to $21 7/8. On January 27, 1998,
the closing price of Premiere Common Stock was $24 1/4.     
 
  Pursuant to the terms of the Merger Agreement, each holder of shares of
Xpedite Common Stock exchanged pursuant to the Merger Agreement who otherwise
would have been entitled to receive a fraction of a share of Premiere Common
Stock will receive, in lieu thereof, cash (without interest) in an amount
equal to such fractional part of a share of Premiere Common Stock multiplied
by the last sale price for the Premiere Common Stock as reported on Nasdaq on
the last trading day immediately preceding the Effective Time as reported in
The Wall Street Journal. No such holder will be entitled to vote or to
exercise any other rights as a stockholder in respect of any fractional
shares.

DISTRIBUTION OF MERGER CONSIDERATION
 
  Prior to the Effective Time, Xpedite and Premiere will select an Exchange
Agent. As soon as reasonably practicable after the Effective Time, the Exchange
Agent will mail to each record holder of Xpedite Common Stock a form of
transmittal letter (a "Letter of Transmittal") and instructions for the
surrender of Xpedite Certificates in exchange for the Merger Consideration. The
Letter of Transmittal will specify that risk of loss and title to Xpedite
Certificates surrendered by Xpedite stockholders will pass upon delivery
thereof to the Exchange Agent. Upon surrender of Xpedite Certificates for
cancellation to the Exchange Agent, together with a Letter of Transmittal duly
completed and executed and any other documents required by such instructions,
the holder of such Xpedite Certificates will be entitled to receive for each of
the shares of Xpedite Common Stock formerly represented by such Xpedite
Certificates (x) the Merger Consideration, including cash in lieu of any
fractional shares of Premiere Common Stock to which such holder is entitled,
and (y) any dividends or distributions to which such holder may be entitled, in
each such case without any interest thereon and less any required withholding
of taxes, and the Xpedite Certificates so surrendered shall forthwith be
canceled. If payment is to be made to a person other than the person in whose
name an Xpedite Certificate so surrendered is registered on the stock transfer
books of Xpedite, it shall be a condition of payment of such Merger
Consideration that the Xpedite Certificate so surrendered shall be properly
endorsed and otherwise in proper form for transfer and that the person
requesting such payment shall pay to the Exchange Agent any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of the Xpedite Certificate surrendered, or shall establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
applicable. Until surrendered as described herein, each Xpedite Certificate
(other than Xpedite Certificates representing shares held by Xpedite in its
treasury) will represent for all purposes only the right to receive the Merger
Consideration for each share of Xpedite Common Stock represented thereby.
 
  Pursuant to the terms of the Merger Agreement, neither Premiere, Xpedite, nor
the Exchange Agent will be liable to any holder of a Xpedite Certificate for
any Merger Consideration delivered in respect of such Xpedite Certificate or
the shares of Xpedite Common Stock formerly represented thereby to a public
official pursuant to any abandoned property, escheat, or other similar law.
 
  No dividends or distributions that are declared on shares of Premiere Common
Stock will be paid to persons entitled to receive certificates representing
shares of Premiere Common Stock until such persons surrender their Xpedite
Certificates. Upon such surrender, there will be paid to the person in whose
name the certificates representing such shares of Premiere Common Stock will be
issued, any dividends or distributions with respect to such shares of Premiere
Common Stock which have a record date on or after the Effective Time and have
become payable between the Effective Time and the time of such surrender. In no
event will the person entitled to receive such dividends or distributions be
entitled to receive interest thereon.
 
TREATMENT OF OPTIONS AND WARRANTS
 
  The Merger Agreement provides that, at the Effective Time, each option and
warrant (an "Xpedite Option" or, collectively, the "Xpedite Options") granted
pursuant to Xpedite's 1992, 1993 or 1996 Incentive Stock Option Plans, the
Officers' Contingent Stock Option Plan (the "Xpedite Stock Option Plans"), or
the Non-Employee Directors' Warrant Plan which is outstanding at the Effective
Time, whether or not such Xpedite Option is then vested or exercisable, will,
by virtue of the Merger and without any action on the part of the holder
thereof, be converted into and become rights with respect to Premiere Common
Stock, and Premiere shall assume each Xpedite Option, in accordance with the
terms of the Xpedite Stock Option Plan and stock option or warrant agreement by
which it is evidenced, except that from and after the Effective Time, (i)
Premiere and its Compensation Committee shall be substituted for Xpedite and
the Committee of Xpedite's Board of Directors (including, if applicable, the
entire Board of Directors of Xpedite) administering such Xpedite Stock Option
Plan, (ii) each Xpedite Option assumed by Premiere may be exercised solely for
shares of Premiere Common Stock (or cash, if so provided under the terms of
such Xpedite Option), (iii) the number of shares of Premiere Common Stock
subject to such Xpedite Option shall be equal to the number of whole shares
(rounded down to the nearest whole share) of Xpedite Common Stock subject to
such Xpedite Option immediately prior to the Effective Time
 
                                       59

<PAGE>
 
multiplied by the Exchange Ratio, and (iv) the per share exercise price under
each such Xpedite Option shall be adjusted by dividing the per share exercise
price under each such Xpedite Option by the Exchange Ratio and rounding up to
the nearest cent. Notwithstanding the provisions of clauses (iii) and (iv)
above, each Xpedite Option which is an "incentive stock option" shall be
adjusted as required by Section 424 of the Code, and the regulations
promulgated thereunder, so as not to constitute a modification, extension or
renewal of such Xpedite Option, within the meaning of Section 424(h) of the
Code.
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
  Xpedite will be the surviving corporation resulting from the Merger and will
become a wholly owned subsidiary of Premiere. The Merger Agreement provides
that from and after the Effective Time, the Board of Directors of Xpedite will
consist of the directors of Acquisition Sub immediately prior to the Effective
Time. The officers of Xpedite after the Effective Time are expected to include
officers of both Xpedite and Premiere. It is expected that Mr. Roy B. Andersen,
Jr. will remain as the President and Chief Executive Officer of Xpedite and
will join Premiere's Board of Directors in connection with the Merger.
Additionally, Premiere has agreed that it will seek to add two new independent
directors to the Premiere Board. It is not expected that the consummation of
the Merger will result in any other changes in the Board of Directors of
Premiere.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Certain directors and executive directors of Xpedite have interests,
described herein, that may present them with potential conflicts of interests
in connection with the Merger. Xpedite's Board of Directors is aware of the
conflicts described below and considered them in addition to other matters
described under "--Reasons for the Merger; Xpedite."
 
  Each of the members of Xpedite's Board of Directors and certain executive
officers of Xpedite have agreed pursuant to an individual Stockholder Agreement
with Premiere to vote the shares of Xpedite Common Stock owned by such
stockholders on the Xpedite Record Date in favor of adoption of the Merger
Agreement.
 
  Pursuant to the Merger Agreement, the surviving corporation has agreed to
indemnify all present directors and officers of Xpedite and its subsidiaries
for six years after the Effective Time and will maintain during such period, if
available, a directors' and officers' insurance policy with respect to such
indemnification containing terms comparable to those applicable as of November
13, 1997 to directors and officers of Xpedite.
 
  In 1996, Xpedite adopted the Officers' Contingent Stock Option Plan (the
"Officers' Plan"). Pursuant to the Officers' Plan, options exercisable for a
maximum aggregate of 200,000 shares of Xpedite Common Stock were granted to
certain members of Xpedite's senior management. The options authorized under
the Officers' Plan were to be granted in two equal tranches upon Xpedite's
Common Stock attaining and maintaining certain specified market prices. Options
for 92,500 shares of Xpedite Common Stock (the "Tranche 1 Options") were
granted upon the Xpedite Common Stock attaining and maintaining a price of
$22.50 or more during 1996 as follows: Mr. Andersen--40,000 shares; Mr.
Schmaltz--20,000 shares; Mr. Slifer--20,000 shares; and a former officer of
Xpedite--12,500 shares. Options for an additional 100,000 shares of Xpedite
Common Stock (the "Tranche 2 Options") were to be granted upon Xpedite
attaining and maintaining a price of $30.00 or more during 1997. In April 1997,
the Xpedite Board adopted resolutions to amend the Officers' Plan to eliminate
the Tranche 2 Options, and in lieu thereof, in the event of a merger or
consolidation of Xpedite, the sale of all or substantially all of the assets of
Xpedite, the acquisition by any party of 51% or more of Xpedite Common Stock or
a liquidation or dissolution of Xpedite following which Xpedite's business is
conducted by another entity, cash bonuses were to be payable to senior, mid-
level and low-level management and staff of Xpedite (the "Bonus Plan"). The
approximate total bonuses which were to be paid to certain executive officers
of Xpedite pursuant to the Bonus Plan as a result of the Merger was $1,530,000.
Cash bonuses payable to other employees were to be approximately $860,000 in
the aggregate. The Bonus Plan was terminated in November 1997 and no amounts
will be payable in connection therewith.
 
 
                                       60

<PAGE>
 
  The Directors' Warrant Plan (the "Directors' Plan") adopted by Xpedite in
1996 provides for the issuance by Xpedite of warrants to purchase 25,000 shares
of Xpedite Common Stock at a purchase price of $17.50 per share to non-employee
directors of Xpedite. Pursuant to the Directors' Plan, each of Messrs. Baker,
Campbell, Chefitz and Epstein were awarded warrants to purchase 25,000 shares
of Xpedite Common Stock.
 
  Robert Chefitz, a member of the Xpedite Board who is also a general partner
or executive officer of each of the Patricof Stockholders, owns an interest in
the Patricof Stockholders. Mr. Chefitz also owns an indirect profit interest in
APAX Ventures IV and APAX Ventures IV International Partners LP (collectively,
the "APAX Funds"), which in turn owns shares of XSL. Mr. Chefitz has not
participated and does not participate in the management of the APAX Funds. The
Patricof Stockholders and the APAX Funds, respectively, have or have had
investments in businesses other than Xpedite and XSL, respectively;
accordingly, the value to Mr. Chefitz of his interest in the Patricof
Stockholders and the APAX Funds, respectively, is dependent in part upon the
performance of such other investments, and cannot be calculated at this time.
 
  John C. Baker, a member of the Xpedite Board, is a former general partner or
executive officer of each of the Patricof Stockholders. Mr. Baker retains an
interest in the Patricof Stockholders. The Patricof Stockholders have or have
had investments in businesses other than Xpedite; accordingly, the value to Mr.
Baker of his interest in the Patricof Stockholders is dependent in part on the
performance of such other investments, and cannot be calculated at this time.
 
  As members of the Special Committee of the Xpedite Board, Messrs. Philip A.
Campbell and Robert Chefitz are each entitled to a fee equal to $25,000 plus
$1,500 for each eight hours of time which such Special Committee member devoted
to the business of the Special Committee. The aggregate amount of such fees
payable is expected to be approximately $250,000.
 
  The current executive officers of Xpedite will be the officers of the
Surviving Corporation. Each of these officers has entered into an employment
agreement with Xpedite which will remain effective after consummation of the
Merger.
 
  To facilitate the retention of management and other key employees of Xpedite,
Premiere has agreed to pay up to $2,500,000 of "stay bonuses." The "stay
bonuses" will be allocated to the following executive officers of Xpedite in
the amounts set forth next to their name: Mr. Andersen--$530,000; Mr. Slifer--
$305,000; Mr. Schmaltz--$305,000; Mr. Vaters--$415,000; and Mr. DeVita--
$220,000. In addition, $725,000 of the stay bonuses will be allocated among
approximately 40 other individuals selected by Premiere (after consulting with
Roy Andersen) in a manner consistent with the current relative salary and
position of those individuals. Such bonuses vest and become due and payable as
follows: 1/3 at the Effective Time; 1/3 on the 91st day after the Effective
Time; and 1/3 on the 121st day after the Effective Time; provided, however that
Premiere shall not be obligated to pay any bonus amounts to any individual who
terminates his employment without "good reason" or whose employment is
terminated for "cause" as such terms are defined in such individuals' current
employment agreements with Xpedite.
   
  In addition to the "stay bonuses," Premiere intends to issue Key Xpedite
Employee Options (as defined in "Summary--Stock Plan Amendment") to the
following persons in the amounts set forth next to their name: Mr. Andersen--
500,000; Mr. Slifer--300,000; Mr. Schmaltz--150,000; Mr. Vaters--200,000; Mr.
DeVita--150,000; and David Proctor, President of XSL--250,000. In addition, up
to 450,000 Key Xpedite Employee Options will be allocated among other current
employees of Xpedite and to individuals that Premiere recruits to join the
Xpedite management team. The Key Xpedite Employee Options will be granted at
the fair market value of Premiere Common Stock on the date of grant and will
generally vest ratably over a four year period.     
 
CONDITIONS TO CONSUMMATION
 
  The obligations of Xpedite and Premiere to consummate the Merger are subject
to the satisfaction or waiver (to the extent permitted) of the following

Common Stock pursuant to the Merger Agreement by the requisite vote; (iii) the
required regulatory approvals and consents described under "--Regulatory
Approvals" shall have been received and shall be in effect at the Effective
Time; (iv) there shall not be in effect any law or order of a court or
governmental or regulatory agency of competent jurisdiction directing that the
Merger not be consummated; (v) the shares of Premiere Common Stock issuable
pursuant to the Merger Agreement shall have been approved for listing on
Nasdaq; (vi) Premiere shall have received a written opinion from Alston &
Bird, dated as of the Effective Time, as to certain federal income tax

Joint Proxy Statement/Prospectus is a part shall have been declared effective
under the Securities Act by the SEC and shall not be subject to a stop order
or a proceeding by the SEC seeking a stop order; (viii) the representations
and warranties of the other party as set forth in the Merger Agreement shall
be accurate in all material respects, as of the date of the Merger Agreement
and the Effective Time (except where a representation or warranty speaks as of

accurate only as of such date); (ix) the other party shall have performed in

The obligation of Premiere to consummate the Merger is further subject to the
satisfaction or waiver of the following condition: all conditions precedent to
the closing of the transactions contemplated by the XSL Purchase Agreement
shall have been satisfied, and such transactions shall have been consummated

(which transaction occurred on December 17, 1997).     
 
  The conditions to consummation of the Merger may be waived, in whole or in
part, and the time for the performance of any of the obligations of the
parties to the Merger Agreement may be extended, in each case to the extent
permissible under applicable law, by the parties to the Merger Agreement in
writing. See "--Amendment and Waiver."
 
  No assurances can be provided as to when or if all of the conditions
precedent to the Merger can or will be satisfied or waived by the appropriate
party. As of the date of this Joint Proxy Statement/Prospectus, the parties
have no reason to believe that any of the conditions set forth above will not
be satisfied.
 
REGULATORY APPROVALS
 
  HSR Act. Under the Hart-Scott Rodino Antitrust Improvements Act of 1976 (the
"HSR Act"), and the rules that have been promulgated thereunder by the Federal
Trade Commission (the "FTC"), the Merger may not be consummated until
notifications have been given and certain information has been furnished to
the FTC and the Antitrust Division of the United States Department of Justice
(the "Antitrust Division") and specified waiting period requirements have been
satisfied.
   
  Pursuant to the requirements of the HSR Act, Premiere and Xpedite each filed
a Notification and Report Form with the Antitrust Division and the FTC on
January 8, 1998 requesting early termination of the waiting period under the
HSR Act. Premiere and Xpedite's request for early termination of the waiting
period under the HSR Act was granted and such termination became effective on
January 20, 1998. The requirements of the HSR Act will be satisfied if the
Merger is consummated within one year from the termination of the waiting
period.     
 
  At any time before or after the consummation of the Merger, and
notwithstanding the granting of early termination or the expiration of the
waiting period under the HSR Act, the Antitrust Division or the FTC could take
such action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the consummation of the Merger or
seeking divestiture of substantial assets of Premiere or Xpedite. Private
parties (including individual states) may also seek to take legal action under
the antitrust laws
 
                                      62
<PAGE>
 
under certain circumstances. Based on information available to them, Premiere
and Xpedite believe that the Merger can be effected in compliance with
applicable federal and state antitrust laws. However, there can be no
assurance that a challenge to the consummation of the Merger on antitrust
grounds will not be made or that, if such a challenge were made, Premiere and
Xpedite would prevail or would not be required to accept certain adverse
conditions in order to consummate the Merger.
 
  Other than the approvals discussed above, Premiere and Xpedite are not aware
of any federal, state or foreign regulatory requirements that must be complied
with or approval that must be obtained in connection with the Merger other
than the filing with the SEC of this Joint Proxy Statement/Prospectus and
compliance with applicable state securities laws and regulations. Should any
such approval be required, it is currently contemplated that such approval
will be sought.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
  Xpedite generally has agreed in the Merger Agreement that, pending
consummation of the Merger or termination of the Merger Agreement, unless the
prior consent of Premiere is obtained or except as required by the XSL
Purchase Agreement, Xpedite will operate its business and cause the business
of its subsidiaries to be operated only in the ordinary course consistent with
past practice, and will use all reasonable efforts to preserve its and its
subsidiaries' business organizations, keep available the service of its
officers, employees, and consultants, and those of its subsidiaries, and
preserve present relationships with customers, suppliers, and others which
Xpedite or any of its subsidiaries have significant business relationships. In
addition, Xpedite has agreed not to take certain actions relating to the
operation of its business, except as contemplated by the Merger Agreement and

       business in accordance with past
 
                                      63
<PAGE>
 
      practice and increases provided for in employment agreements, granting
      any severance or termination pay to, or entering into or amending any
      employment or severance agreement with, any director, officer, or other
      employee of Xpedite or any its subsidiaries, or establishing, adopting,

        XSL Purchase Agreement (other than converting the purchase price and

  (xiii) taking, or agreeing to take, any of the actions described above, or
         any action which would make any the representations or warranties of
         Xpedite contained in the Merger Agreement untrue or incorrect or
         prevent Xpedite from performing its covenants contained in the
         Merger Agreement.
 
  Premiere generally has agreed in the Merger Agreement that, pending
consummation of the Merger or termination of the Merger Agreement, unless the
prior consent of Xpedite is obtained, it will conduct its business, and cause
the business of its subsidiaries to be conducted, in a manner designed in its
reasonable judgment to enhance the long-term value of the Premiere Common Stock
and the business prospects of Premiere and its subsidiaries, and will use its
reasonable best efforts to preserve intact its and its subsidiaries' core
businesses and goodwill with their respective present officers, employees,
consultants, customers, suppliers and other persons with which Premiere or any
of its subsidiaries has significant business relations. The foregoing, however,
does not prevent Premiere or its subsidiaries from acquiring any assets or
businesses if such action is, in Premiere's judgment, desirable in the conduct
of Premiere's and its subsidiaries' businesses. In addition, Premiere has
agreed not to take certain actions relating to the operation of its business,
except as contemplated by the Merger Agreement, pending consummation of the
Merger or the termination of the Merger Agreement, without the prior approval
of Xpedite. These actions generally include, without limitation:
 
  (i) amending or otherwise changing Premiere's Articles or Bylaws in any
      manner adverse to the holders of Xpedite Common Stock as compared to
      the current holders of Premiere Common Stock;
 
  (ii) changing any method of accounting or accounting practice, except as
       required by generally acceptable accounting principles or by law; or
 
  (iii) taking, or agreeing to take, any of the actions described above, or
        any action which would make any the representations or warranties of
        Premiere contained in the Merger Agreement untrue or incorrect or
        prevent Premiere or Acquisition Sub from performing their respective
        covenants contained in the Merger Agreement.
 
 
                                       64
<PAGE>
 
  Furthermore, Xpedite has agreed not to authorize, and to use its reasonable
efforts to cause its officers, directors, employees, or agents not to,
directly or indirectly, (i) solicit, initiate, or encourage or take any other
action to facilitate the institution of any inquiries or proposals regarding
any merger, reorganization, consolidation, business combination,
recapitalization, liquidation, dissolution, sale of any significant portion of
assets, sale of shares of capital stock or similar transaction involving
Xpedite or any of its subsidiaries other than the Merger ("Acquisition
Proposal"); (ii) engage in negotiations or discussions concerning, or provide
any nonpublic information or assistance to any person in connection with any
Acquisition Proposal; or (iii) agree to, approve or recommend any Acquisition
Proposal. Xpedite's Board of Directors, however, is entitled to consider,
negotiate, discuss, approve, and recommend to Xpedite's stockholders a bona
fide Acquisition Proposal not solicited in violation of the Merger Agreement,
provided that the Xpedite Board determines in good faith that it is required
to do so in order to discharge properly is fiduciary duties to Xpedite's
stockholders. Xpedite must immediately notify Premiere after receipt of any
Acquisition Proposal or any modification of or amendment to any Acquisition
Proposal, or any request for nonpublic information relating to Xpedite or its
subsidiaries or access to the properties, books or records of Xpedite or its
subsidiaries by any person or entity that informs Xpedite that it is
considering making, or has made, an Acquisition Proposal, and Xpedite must
keep Premiere informed, on a reasonably current basis, as to the status and
details of any bona fide consideration, negotiations or discussions concerning
an Acquisition Proposal.
 
TERMINATION AND POSSIBLE EXCHANGE RATIO INCREASE
 
  Termination Rights of Both Xpedite and Premiere. Either Premiere or Xpedite
may terminate the Merger Agreement and abandon the Merger, before or after the
approval by stockholders of Premiere or Xpedite, if: (i) the Boards of
Directors of Premiere and Xpedite mutually agree; (ii) the Merger has not been
consummated by April 30, 1998, provided that the date will be extended until
May 30, 1998 (the "Outside Termination Date"), if the Joint Proxy
Statement/Prospectus has been mailed to the stockholders of both Xpedite and
Premiere before April 30, 1998, and provided further that the right to so
terminate the Merger Agreement will not be available to any party whose
failure to fulfill any obligation under the Merger Agreement resulted in the
failure of the Merger to occur on or before such date; (iii) any court of
competent jurisdiction or other governmental, regulatory or administrative
agency or commission has issued an order or taken any other action having the
effect of permanently restraining, enjoining or otherwise prohibiting the
Merger and such order or action has become final and nonappealable, provided
that the right to terminate the Merger Agreement shall not be available to any
party who materially contributed to the issuance of any such order or the
taking of such action; (iv) the Xpedite Board recommends an Alternative
Transaction to the Xpedite stockholders; or (v) a tender offer or exchange
offer for 15% or more of the outstanding shares of Xpedite Common Stock is
commenced (other than by Premiere or an affiliate of Premiere) and the Xpedite
Board recommends that the Xpedite stockholders tender their shares in such
tender or exchange offer; provided that Xpedite shall not be entitled to
exercise any termination rights under clauses (iv) or (v) unless (x) any
action of the Xpedite Board referred to in such clauses is required to be
taken by the Xpedite Board in order to properly discharge its fiduciary duties
to Xpedite's stockholders and (y) Xpedite has complied with its obligations
not to solicit Acquisition Proposals.
 
  The term "Alternative Transaction" means (i) a transaction or series of
transactions pursuant to which any person (or group of persons) other than
Premiere or its subsidiaries (a "Third Party") acquires or would acquire more
than 15% of the outstanding shares of Xpedite Common Stock, whether from
Xpedite or pursuant to a tender offer or exchange offer or otherwise, (ii) any
acquisition or proposed acquisition of Xpedite or any of its subsidiaries by a
merger, consolidation or other business combination (including any so-called
"merger of equals" and whether or not Xpedite or any of its subsidiaries is
the entity surviving any such merger or business combination), (iii) any
reorganization, recapitalization, liquidation or dissolution of Xpedite or any
of its subsidiaries (other than the liquidation or dissolution of a wholly-
owned subsidiary of Xpedite or any of its subsidiaries) or (iv) any other
transaction pursuant to which any Third Party acquires or would acquire
control of assets (including for this purpose the outstanding equity
securities of subsidiaries of Xpedite and any entity surviving any merger or
business combination with any subsidiary) of Xpedite or any of its
subsidiaries having a
 
                                      65
<PAGE>
 
fair market value equal to more than 15% of the fair market value of all the
assets of Xpedite and its subsidiaries, taken as a whole, immediately prior to
such transaction.
 
  Additional Termination Rights of Premiere. The Merger Agreement further
provides that it may be terminated by Premiere and the Merger may be abandoned
prior to the Effective Time, before or after the approval by stockholders of
Premiere or Xpedite, (i) in the event the Xpedite Board withdraws, modifies or
changes its approval or recommendation of the Merger Agreement or the Merger
in a manner adverse to Premiere; or (ii) in the event of a material breach by
Xpedite of any representation, warranty, covenant or agreement contained in
the Merger Agreement which has not been cured within 30 days following receipt
by Xpedite of written notice of such breach, in any case such that Xpedite's
conditions to consummation of the Merger set forth in the Merger Agreement
would be incapable of being satisfied by April 30, 1998, provided that
Premiere may not terminate the Merger Agreement if Premiere is itself in
material breach of any of its representations, warranties, covenants or
agreements set forth in the Merger Agreement, such that Xpedite's conditions
to consummation of the Merger set forth in the Merger Agreement would be
incapable of being satisfied by April 30, 1998.
 
  Additional Termination Rights of Xpedite. Finally, Xpedite may terminate the
Merger Agreement and abandon the Merger prior to the Effective Time, before or
after the approval by stockholders of Premiere or Xpedite, (i) if the Board of
Directors of Premiere shall have recommended to the stockholders of Premiere
(x) any acquisition or proposed acquisition of Premiere by a merger,
consolidation or other business combination (including any so-called "merger
of equals" and whether or not Premiere is the entity surviving any such merger
or business combination) in which the consideration to be received by Premiere
stockholders in such business combination shall be other than cash, (y) any
liquidation or dissolution of Premiere, or (z) any transaction or series of
transactions in which Third Parties would acquire substantially all of the
consolidated assets of Premiere; (ii) a tender offer or exchange offer for 50%
or more of the outstanding shares of Premiere Common Stock is commenced and
the Board of Directors of Premiere recommends that the stockholders of
Premiere tender their shares in such tender or exchange offer; (iii) if the
Board of Directors of Premiere shall withdraw, modify or change its approval
or recommendation of the Merger Agreement or the Merger in a manner adverse to
Xpedite; (iv) in the event of a material breach by Premiere of any
representation, warranty, covenant or agreement contained in the Merger
Agreement which has not been cured within 30 days following receipt by
Premiere of written notice of such breach, in any case such that Premiere's
conditions to consummation of the Merger set forth in the Merger Agreement
would be incapable of being satisfied by April 30, 1998, provided that Xpedite
may not terminate the Merger Agreement if Xpedite is itself in material breach
of any of its representations, warranties, covenants or agreements set forth
in the Merger Agreement, such that Premiere's conditions to consummation of
the Merger set forth in the Merger Agreement would be incapable of being
satisfied by April 30, 1998, or (v) as set forth in the paragraph titled
"Possible Exchange Ratio Increase."
 
  Possible Exchange Ratio Increase. If the Xpedite Board so determines by a
vote of a majority of the members of its entire Board, at any time during the
three-business-day period commencing on the day that the Average Closing Price
is determined, if the Average Closing Price shall be less than $24.00 (the
"Threshold Price"); subject, however, to the following: (x) if Xpedite elects
to exercise its termination right pursuant to this clause, it shall give
prompt written notice thereof to Premiere (provided that such notice of
election to terminate may be withdrawn at any time within the three-business-
day period referenced in clause (y) below); (y) during the three-business-day
period commencing with its receipt of such notice, Premiere shall have the
option, in its sole discretion, to elect to increase the Exchange Ratio to
equal the quotient obtained by dividing (I) the product of the Threshold Price
and the Exchange Ratio (as then in effect) by (II) the Average Closing Price;
(z) if Premiere makes an election contemplated by clause (y) within such
three-business-day period, it shall give prompt written notice to Xpedite of
such election and the revised Exchange Ratio, whereupon no termination shall
have occurred pursuant to this clause (v) and the Merger Agreement shall
remain in effect in accordance with its terms (except as the Exchange Ratio
shall have been so modified), and any references in the Merger Agreement to
"Exchange Ratio" shall thereafter be deemed to refer to the Exchange Ratio as
adjusted.
 
 
                                      66
<PAGE>
 
          
  It is not possible to know if the Average Closing Price will be less than
the Threshold Price until the day immediately preceding the date of the
Xpedite Special Meeting and the Premiere Special Meeting. Since the date of
the Merger Agreement, the market price of Premiere Common Stock has been
subject to significant fluctuation, with the high and low closing price
therefor ranging from $28 11/16 to $21 7/8. On January 27, 1998, the closing
price of Premiere Common Stock was $24 1/4. The fairness opinions received by
each of Xpedite and Premiere are based on the conditions in effect at the time
the parties executed the Merger Agreement. In addition, the Merrill Lynch
Opinion expressly assumes that Xpedite would not consummate the Merger under
circumstances where the Threshold Price Termination Right is exercisable.
Accordingly, the Merrill Lynch Opinion does not address the circumstances that
might arise if the Xpedite Board has decided to consummate the Merger in a
case where the Threshold Price Termination Right is exercisable but the
Premiere Board has chosen not to increase the Exchange Ratio. Likewise, the
Prudential Securities Opinion does not address the circumstance where the
Average Closing Price is below the Threshold Price and the Premiere Board
chooses to increase the Exchange Ratio. See "The Merger--Opinions of Financial
Advisors." While the Xpedite Board currently intends to exercise its right to
terminate the Merger Agreement if the Average Closing Price is less than the
Threshold Price, it has not made a final determination and it is not obligated
to exercise such right and the final decision as to whether it would exercise
such right in such event, or to withdraw notice of termination as provided in
the Merger Agreement, would be made at the time the termination right becomes
exercisable or in the event that the Premiere Board declines to increase the
Exchange Ratio, as applicable. While the Premiere Board does not currently
intend to increase the Exchange Ratio in the event Xpedite elects to exercise
its termination right, its final decision whether to increase the Exchange
Ratio would be made if and when Xpedite were to exercise its termination
right. In considering whether to exercise their respective rights in each
situation, each of the Xpedite and the Premiere Boards would, consistent with
its fiduciary duties, take into account all relevant facts and circumstances
that exist at such time and would consult with its respective financial
advisors and legal counsel. APPROVAL OF THE MERGER AGREEMENT BY THE
STOCKHOLDERS OF XPEDITE AT THE XPEDITE SPECIAL MEETING AND APPROVAL OF THE
ISSUANCE OF SHARES OF PREMIERE COMMON STOCK PURSUANT TO THE MERGER AGREEMENT
BY THE STOCKHOLDERS OF PREMIERE AT THE PREMIERE SPECIAL MEETING WILL CONFER ON
THE XPEDITE BOARD AND THE PREMIERE BOARD, RESPECTIVELY, THE POWER, CONSISTENT
WITH THE FIDUCIARY DUTIES OF SUCH BOARDS, TO ELECT TO CONSUMMATE THE MERGER IF
THE AVERAGE CLOSING PRICE IS LESS THAN THE THRESHOLD PRICE (IN THE CASE OF THE
XPEDITE BOARD) OR TO ELECT TO INCREASE THE EXCHANGE RATIO IN THE EVENT XPEDITE
ELECTS TO EXERCISE ITS TERMINATION RIGHT (IN THE CASE OF THE PREMIERE BOARD)
WITHOUT ANY FURTHER ACTION BY, OR RESOLICITATION OF, THE STOCKHOLDERS OF
XPEDITE AND PREMIERE, AS THE CASE MAY BE.     
 
EXPENSES AND TERMINATION FEES
 
  Expenses Generally. The Merger Agreement provides that, except for the
termination fees described below, each party is responsible for its own
expenses incident to preparing for, entering into, and carrying out the Merger
Agreement and the consummation of the transactions contemplated thereby. Any
party who willfully breaches any of its representations, warranties,
covenants, or agreements set forth in the Merger Agreement, however, will be
liable for damages occasioned by such breach, including any expenses incurred
by the other party in connection with the Merger Agreement.
 
  Termination Fees. In the event that the Merger Agreement is terminated by
either party for any reason, Xpedite shall pay to Premiere an amount equal to
$9,500,000 (the "Premiere Fee") plus all documented fees and expenses incurred
by Premiere and its subsidiaries in connection with or related to the
authorization, preparation, regulation, execution and performance of the
Merger Agreement and the transactions contemplated thereby (including, without
limitation, all fees and expenses of counsel, accountants, investment bankers,
experts, consultants, banks and other financial institutions) (the "Premiere
Expenses") up to a maximum of $1,000,000 in the aggregate, provided, that
Xpedite shall not be obligated to pay the Premiere Fee or any Premiere
Expenses if the Merger Agreement is terminated under the following conditions:
 
  (i) pursuant to the mutual agreement of Premiere and Xpedite;
 
 
                                      67

       paragraph titled "--Termination and Possible Exchange Ratio Increase;
       Additional Termination Rights of Xpedite";
 
  (iii) by Xpedite pursuant to clause (ii) of the paragraph titled "--
        Termination and Possible Exchange Ratio Increase; Termination Rights
        of Both Xpedite and Premiere" solely as a result of the failure to
        satisfy any of the conditions to the consummation of the Merger
        relating to (t) the expiration of the waiting period under the HSR
        Act and the requirements of governmental authorities in foreign
        jurisdictions, (u) the issuance of a governmental order that
        prohibits or restricts the Merger (other than if any such order
        results from claims made by stockholders of Xpedite or any Third
        Party proposing an Alternative Transaction), (v) the failure to
        receive the required tax opinions, (w) the failure of the
        Registration Statement of which this Joint Prospectus/Proxy Statement
        is a part to be declared effective by the SEC, (x) the failure of
        shares of Premiere Common Stock issuable pursuant to the Merger to
        have been approved for listing on Nasdaq, (y) the breach by Premiere
        of any of its representations, warranties, covenants and agreements
        in the Merger Agreement, or (z) the occurrence of a material adverse
        effect with respect to Premiere;
 
  (iv) by either Premiere or Xpedite pursuant to clause (ii) of the paragraph
       titled "--Termination and Possible Exchange Ratio Increase;
       Termination Rights of Both Premiere and Xpedite" solely as a result of
       the failure of the Premiere stockholders to approve the issuance of
       Premiere Common Stock in the Merger or any other aspect of the Merger
       which is submitted for their approval at the Premiere Stockholders
       Meeting, but only if the stockholders of Xpedite have adopted the
       Merger Agreement;
 
  (v) by Premiere pursuant to clause (ii) of the paragraph titled "--
      Termination and Possible Exchange Ratio Increase; Termination Rights of
      Both Xpedite and Premiere" solely as a result of the failure to satisfy
      any of the conditions to the consummation of the Merger relating to (u)
      the expiration of the waiting period under the HSR Act and the
      requirements of governmental authorities in foreign jurisdictions, (v)
      the failure to receive the required tax opinions, (w) the failure of
      the Registration Statement of which this Prospectus/Proxy Statement is
      a part to be declared effective by the SEC, (x) the failure of shares
      of Premiere Common Stock issuable pursuant to the Merger to have been
      approved for listing on Nasdaq, or (y) the failure to receive the
      required Xpedite affiliate letters; or
 
  (vi) by either Xpedite or Premiere pursuant to clause (iii) of the
       paragraph titled "--Termination and Possible Exchange Ratio Increase;
       Termination Rights of Both Xpedite and Premiere," if any such
       injunction results from claims made by stockholders of Xpedite or any
       Third Party proposing an Alternative Transaction;
 
and, provided further, that Xpedite shall not be obligated to pay the Premiere
Fee but shall only be obligated to reimburse Premiere for the amount of
Premiere Expenses incurred by it up to a maximum of $1,000,000 if the Merger
Agreement is terminated under the following conditions:
 
  (i) by Premiere pursuant to clause (ii) of the paragraph titled "--
      Termination and Possible Exchange Ratio Increase; Termination Rights of
      Both Xpedite and Premiere" solely as a result of the failure to satisfy
      the condition to consummation of the Merger related to the UK Purchase
      Agreement (other than as a result of Xpedite's breach of a
      representation or warranty in the UK Purchase Agreement or Xpedite's
      failure to fulfill any of its material obligations in the UK Purchase
      Agreement) or the occurrence of a material adverse effect with respect
      to Xpedite; or
 
  (ii) by Xpedite pursuant to clause (iii) of the paragraph titled "--
       Termination and Possible Exchange Ratio Increase; Additional
       Termination Rights of Xpedite" if there shall have occurred a material
       adverse effect with respect to Xpedite after the date of the Merger
       Agreement and prior to the date on which Premiere's Board of Directors
       withdrew, modified or changed its approval or recommendation of the
       Merger Agreement or the Merger in a manner adverse to Xpedite.
 
  Notwithstanding the above, Premiere shall pay to Xpedite an amount equal to
$9,500,000 plus all documented fees and expenses incurred by Xpedite and its
subsidiaries in connection with or related to the authorization, preparation,
regulation, execution and performance of the Merger Agreement and the Prior

Agreement and the transactions contemplated hereby and thereby (including,
without limitation, all fees and expenses of counsel, accountants, investment
bankers, experts, consultants, banks and other financial institutions) up to a
maximum of $1,000,000 in the aggregate in the event the Merger Agreement is
terminated under the following conditions:
 
  (i) by Xpedite pursuant to clauses (i), (ii) and (iv) of the paragraph
      titled "--Termination and Possible Exchange Ratio Increase; Additional
      Termination Rights of Xpedite;"
 
  (ii) by Xpedite pursuant to clause (ii) of the paragraph titled "--
       Termination and Possible Exchange Ratio Increase; Termination Rights
       of Both Premiere and Xpedite" solely as a result of the failure to
       satisfy any of the conditions to the consummation of the Merger that
       relate to (x) the issuance of a governmental order that prohibits or
       restricts the Merger (other than if any such order results from claims
       made by stockholders of Xpedite or any Third Party proposing an
       Alternative Transaction), (y) the breach by Premiere of any of its
       representations, warranties, covenants and agreements in the Merger
       Agreement, or (z) the occurrence of a material adverse effect with
       respect to Premiere;
 
  (iii) by Xpedite or Premiere pursuant to clause (ii) of the paragraph
        titled "--Termination and Possible Exchange Ratio Increase;
        Termination Rights of Both Premiere and Xpedite" solely as a result
        of the failure of the Premiere stockholders to approve the issuance
        of Premiere Common Stock in the Merger or any other aspect of the
        Merger which is submitted for their approval at the Premiere
        Stockholders Meeting, but only if the stockholders of Xpedite have
        adopted the Merger Agreement;
 
  (iv) by Xpedite or Premiere pursuant to clause (iii) of the paragraph
       titled "--Termination and Possible Exchange Ratio Increase;
       Termination Rights of Both Xpedite and Premiere," if any such
       injunction results from claims made by stockholders of Premiere or any
       Third Party proposing an Alternative Transaction with Premiere, or
 
  (v) by Xpedite pursuant to clause (iii) of the paragraph titled "--
      Termination and Possible Exchange Ratio Increase; Additional
      Termination Rights of Xpedite" (unless there shall have occurred a
      material adverse effect with respect to Xpedite after the date of the
      Merger Agreement and prior to the date on which Premiere's Board of
      Directors withdrew, modified or changed its approval or recommendation
      of the Merger Agreement or the Merger in a manner adverse to Xpedite.
 
AMENDMENT AND WAIVER
 
  To the extent permitted by law, Premiere and Xpedite may amend the Merger
Agreement by written agreement at any time without the approval of the
stockholders of Xpedite, provided that after the approval of the Merger
Agreement by Xpedite's stockholders, no amendment may change the consideration
to be received by Xpedite stockholders or the rights of the Xpedite
stockholders under the Merger Agreement without the requisite approval of such
stockholders.
 
  Prior to or at the Effective Time, either Xpedite or Premiere may also (i)
extend the time for the performance of any of the obligations or other acts of
the other party under the Merger Agreement, (ii) waive any inaccuracies in the
representations and warranties contained in the Merger Agreement or any
document delivered pursuant thereto, or (iii) except to the extent prohibited
by law, waive compliance with any of the agreements or conditions contained in
the Merger Agreement.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a discussion of the material federal income tax
consequences of the Merger. This discussion is based on provisions of the
Code, the Treasury regulations promulgated thereunder and rulings and court
decisions as of the date hereof, all of which are subject to change, possibly
retroactively. The discussion is included for general information purposes
only, applies only to Xpedite stockholders who hold their stock as a capital
asset, and may not apply to Xpedite stockholders who received their stock upon
the exercise of employee stock options or otherwise as compensation or who
have a special tax status including, but not limited to,
 
                                      69
<PAGE>
 
financial institutions, insurance companies, dealers in securities, holders
that are not citizens or residents of the United States and tax-exempt
entities. Premiere and Xpedite have not requested a ruling from the IRS.
 
  It is intended that the Merger will qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Code, and as a condition to
consummation of the Merger each of Premiere and Xpedite will receive an
opinion of Alston & Bird, counsel to Premiere, among other things, as to the
qualification of the Merger as a tax-free reorganization within the meaning of
Section 368(a) of the Code. In order to so qualify, various factual matters
must be true. In this regard, based upon certain factual representations of
officers of Premiere and Xpedite and the terms of the Merger, such counsel has
advised Premiere and Xpedite that the Merger will qualify as a tax-free
reorganization.
 
  Assuming, however, as is anticipated, that the Merger is treated as a
reorganization as defined in Section 368(a) of the Code, based on the
aforementioned opinion of Alston & Bird, Xpedite stockholders will realize the
following material federal income tax consequences:
 
    (i) No gain or loss will be recognized by an Xpedite stockholder upon the
  receipt of Premiere Common Stock solely in exchange for all of its shares
  of Xpedite Common Stock.
 
    (ii) The aggregate tax basis of the Premiere Common Stock received by a
  Xpedite stockholder in the transaction will, in each instance, be the same
  as the aggregate tax basis of the Xpedite Common Stock surrendered in
  exchange therefor less any basis allocated to any fractional share of
  Premiere Common Stock settled by cash payment.
 
    (iii) The holding period of the Premiere Common Stock received by an
  Xpedite stockholder (including the holding period of any fractional share
  interest) will include the holding period of the Xpedite Common Stock
  surrendered in exchange therefor, provided the Xpedite Common Stock was
  held as a capital asset on the date of the exchange.
 
    (iv) The payment of cash in lieu of fractional shares of Premiere Common
  Stock will be treated as if the fractional shares were issued as part of
  the exchange and then redeemed by Premiere. These cash payments will be
  treated as having been received as distributions in full payment in
  exchange for the fractional shares of Premiere Common Stock redeemed as
  provided in Section 302(a). Generally, any gain or loss recognized upon
  such exchange will be capital gain or loss, provided the fractional share
  would constitute a capital asset in the hands of the exchanging
  stockholder.
 
  Upon the sale or exchange of Premiere Common Stock, a holder of such stock
generally will recognize capital gain or loss equal to the difference between
the amount of cash and the fair market value of any property received upon the
sale or exchange and such holder's adjusted tax basis in the Premiere Common
Stock. Under recently enacted legislation, capital gains recognized by certain
non-corporate holders of Premiere Common Stock generally will be subject to a
maximum federal income tax rate of 20% if the shares sold or exchanged are
held for more than 18 months, and to a maximum federal income tax rate of 28%
if such shares are held for more than one year but are not held for more than
18 months. Tax consequences to dealers in Premiere Common Stock, non-United
States holders of Premiere Common Stock or others who have a special tax
status (including, without limitation, financial institutions, insurance
companies and tax-exempt entities) or to persons who received their shares
through the exercise of employee stock options or otherwise as compensation
may be different and such persons should consult their tax advisors as to the
tax consequences of a sale or exchange of Premiere Common Stock.
 
  Each Xpedite stockholder who receives Premiere Common Stock in the Merger
will be required to attach a statement to such stockholder's federal income
tax return for the year of the Merger which describes the facts of the Merger,
including the stockholder's basis in the Xpedite Common Stock exchanged, and
the number of shares of Premiere Common Stock received in exchange for Xpedite
Common Stock. Each stockholder should also keep as part of such stockholder's
permanent records information necessary to establish such stockholder's basis
in, and holding period for, the Premiere Common Stock received in the Merger.
 
 
                                      70
<PAGE>
 
  If the Merger fails to qualify as a tax-free reorganization for any reason,
the principal federal income tax consequences, under currently applicable law,
would be as follows: (i) no gain or loss would be recognized to Premiere or
Xpedite as a result of the Merger; (ii) gain or loss would be recognized by
the holders of Xpedite Common Stock upon the exchange of such shares in the
Merger for shares of Premiere Common Stock; (iii) the tax basis of the
Premiere Common Stock to be received by the holders of Xpedite Common Stock in
the Merger would be the fair market value of such shares of Premiere Common
Stock at the Effective Time; and (iv) the holding period of such shares of
Premiere Common Stock to be received by Xpedite stockholders pursuant to the
Merger would begin the day after the Effective Time.
 
  BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE
PARTICULAR CIRCUMSTANCES OF EACH XPEDITE STOCKHOLDER, EACH HOLDER OF XPEDITE
COMMON STOCK IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISOR TO DETERMINE
THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE
APPLICATION AND EFFECT OF FOREIGN, STATE AND LOCAL INCOME AND OTHER TAX LAWS).
 
ACCOUNTING TREATMENT
 
  The Merger is anticipated to be accounted for on a pooling-of-interests
accounting basis. Under this method of accounting, as of the Effective Time,
the assets and liabilities of Xpedite would be added to those of Premiere at
the recorded book values and the stockholders' equity accounts of Premiere and
Xpedite would be combined on Premiere's consolidated balance sheet.
 
RESALES OF PREMIERE COMMON STOCK
 
  The shares of Premiere Common Stock issued in connection with the Merger
will be freely transferable under the Securities Act, except for shares issued
to any stockholder who may be deemed to be an "affiliate" (generally
including, without limitation, directors, certain executive officers, and
beneficial owners of 10% or more of any class of capital stock) of Xpedite for
purposes of Rule 145 under the Securities Act as of the date of the Xpedite
Special Meeting. Such affiliates may not sell their shares of Premiere Common
Stock acquired in connection with the Merger except pursuant to an effective
registration statement under the Securities Act or other applicable exemption
from the registration requirements of the Securities Act. Premiere may place
restrictive legends on certificates representing Premiere Common Stock issued
to all persons who are deemed to be "affiliates" of Xpedite under Rule 145. In
addition, Xpedite has agreed to use its reasonable efforts to cause each
person or entity that is an "affiliate" to enter into a written agreement in
substantially the form attached to the Merger Agreement relating to such
restrictions on sale or other transfer. This Joint Proxy Statement/Prospectus
does not cover resales of Premiere Common Stock received by any person who may
be deemed to be an affiliate of Xpedite.
 
REGISTRATION RIGHTS
 
  As provided in the Merger Agreement, each person (a "Large Stockholder") who
is precluded by Rule 145 under the Securities Act from selling or disposing of
all of their shares of Premiere Common Stock received in the Merger (the
"Registrable Securities") within one calendar quarter is entitled to the
registration rights set forth in Exhibit C to the Merger Agreement. The
following is a summary of the registration rights and is qualified in its
entirety by reference to such Exhibit C to the Merger Agreement.
 
  For a period of three months commencing 30 days after financial results
covering at least 30 days of combined operations of Premiere and Xpedite have
been published, the Large Stockholders have a one-time right to require
Premiere to file a registration statement under the Securities Act relating to
all or part of their Registrable Securities (a "Demand Registration").
Premiere is obligated to use its commercially reasonable efforts to effect a
Demand Registration as soon as reasonably practical after the request is made,
except that Premiere has the right, under certain circumstances, to delay the
effective date of a registration statement or any
 
                                      71
<PAGE>
 
sales thereunder for a period not to exceed 120 days from the date of the
request for registration. In addition, Premiere is not be obligated to effect
a Demand Registration (i) for less than one million shares or (ii) within
three months of a Large Stockholder selling any Registrable Securities
pursuant to a Piggyback Registration (defined below). Unless Premiere shall
otherwise consent, any offering pursuant to a Demand Registration shall be
underwritten and Premiere shall select the underwriters and any additional
investment bankers to be used.
 
  If Premiere proposes to file a registration statement under the Securities
Act with respect to an offering for Premiere's own account or for the account
of any holders of Premiere Common Stock other than the Large Stockholders, any
Large Stockholder may request registration under the Securities Act of all or
part of its Registrable Securities on the same terms and conditions as
Premiere or such other holders of Premiere Common Stock (a "Piggyback
Registration"). In the case of a Piggyback Registration, Premiere has the
right to terminate or withdraw any registration undertaken by it prior to the
effectiveness of such registration whether or not any Large Stockholder has
elected to include Registrable Securities in such registration.
 
  These registration rights are subject to certain limitations and
restrictions, including the right of the underwriters of an underwritten
offering to limit the numbers of shares offered in such registration if such
underwriter determines that the number of shares requested to be registered
cannot be underwritten.
 
  Premiere is required to bear the expenses of registration, except for
underwriting discounts and commissions related to the Registrable Securities
and the out of pocket expenses of the Large Stockholders (including their
counsel fees and expenses). Premiere and any Large Stockholder whose
Registrable Securities are included in any Demand or Piggyback Registration
have certain indemnification and contribution rights against one another for
certain losses, claims, damages or liabilities.
 
STOCKHOLDER AGREEMENTS
 
  As provided in the Merger Agreement, Premiere and each of the directors of
Xpedite, certain executive officers of Xpedite and certain holders of five
percent or more of the outstanding shares of Xpedite Common Stock (the
"Stockholders") have entered into Stockholder Agreements that contain, among
other things, the agreement to vote the shares of Xpedite Common Stock owned
by the Stockholders on the Xpedite Record Date in favor of the Merger. The
following is a summary of the Stockholder Agreements and is qualified in its
entirety by reference to the Stockholder Agreements, a copy of which is
attached as Exhibit B to the Merger Agreement in Annex A to this Joint Proxy
Statement/Prospectus.
 
  Under the Stockholder Agreements, the Stockholders agreed to, or have given
the officers of Premiere an irrevocable proxy to, vote the shares of Xpedite
Common Stock owned by the Stockholders on the Xpedite Record Date in favor of
the adoption of the Merger Agreement.
 
  The Stockholder Agreements terminate upon the earlier of the termination of
the Merger Agreement and the Effective Time of the Merger.

               PRO FORMA CONDENSED COMBINED FINANCIAL DATA     
 
  The following unaudited pro forma condensed combined balance sheet as of
September 30, 1997, reflects the assumed consummation of the Merger accounted
for under the pooling-of-interests method of accounting and the assumed
consummation of the XSL Acquisition accounted for under the purchase method as
of that date. The following unaudited pro forma condensed combined statements
of income for the nine months ended September 30, 1997, and for the year ended
December 31, 1996, reflect the assumed consummation of the Merger accounted
for under the pooling-of-interests method as of the beginning of each such
period and the assumed consummation of the XSL Acquisition accounted for under
the purchase method as of January 1, 1996. The following unaudited pro forma
condensed combined statement of income for each year in the three years ended
December 31, 1994, December 31, 1995 and December 31, 1996, reflect the
assumed consummation of the Merger accounted for under the pooling-of-
interests method of accounting as of the beginning of each such period. No
adjustment has been included in the pro forma amounts for any anticipated cost
savings or other synergies. See "The Merger--Accounting Treatment."
 
  In addition, the unaudited pro forma condensed combined financial
information gives effect to Premiere's acquisition of TeleT on September 18,
1996 as though the transaction occurred January 1, 1996. Premiere exchanged
498,187 shares of its common stock and paid approximately $2.8 million in cash
for TeleT. This acquisition has been accounted for under the purchase method
of accounting.
 
  The number of pro forma weighted average common shares and common share
equivalents used to compute pro forma net income per share reflects the
aggregate of the weighted average outstanding shares or owners' interests in
Xpedite, adjusted to equivalent shares of Premiere for all periods presented.
 
  Certain balance sheet and income statement amounts in the pro forma
financial information of Xpedite have been reclassified to conform with the
unaudited pro forma combined financial information presentation and disclosure
practices of Premiere.
 
  The pro forma financial data has been prepared by the managements of
Premiere and Xpedite based upon the historical financial statements of

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
 
  The unaudited pro forma condensed combined financial information gives effect
to the Merger as though such transaction occurred on January 1, 1994. Premiere
and Xpedite entered into a definitive merger agreement on November 13, 1997.
Under the terms of the merger agreement, Premiere will exchange its common
shares for Xpedite's using an exchange ratio which values Xpedite's shares at
$34 per share and Premiere's shares at its average trading price for the 20
trading days preceding the date on which Xpedite stockholders vote on the
Merger. Except in certain limited circumstances, the exchange ratio is subject
to a maximum and minimum ratio of the number of Premiere's shares to be issued
for each share of Xpedite's of 1.25 and 0.8675 per share, respectively. The pro
forma unaudited combined financial information reflect this transaction
assuming an exchange ratio of 1.25 shares of Premiere's stock for each
outstanding share of Xpedite.
   
  The unaudited pro forma condensed combined statement of operations also gives
effect to the XSL Acquisition as though such transaction occurred effective
January 1, 1996. The unaudited pro forma condensed combined balance sheet also
gives effect to the XSL Acquisition as though the transaction occurred
September 30, 1997. These companies entered into a definitive agreement on
August 8, 1997, under which Xpedite paid approximately $85.5 million in cash to
acquire XSL. The XSL Acquisition will be accounted for under the purchase
method of accounting. The historical financial statements of XSL are presented
herein on a basis consistent with generally accepted accounting principles of
the United States.     
 
  In addition, the unaudited pro forma condensed combined financial information
gives effect to Premiere's acquisition of TeleT on September 18, 1996 as though
the transaction occurred January 1, 1996. Premiere exchanged 498,187 shares of
its common stock and paid approximately $2.8 million in cash for TeleT. This
acquisition has been accounted for under the purchase method of accounting.
 
  The number of pro forma weighted average common shares and common share
equivalents used to compute pro forma net income per share reflects the
aggregate of the weighted average outstanding shares or owners' interests in
Xpedite, adjusted to equivalent shares of Premiere for all periods presented.
 
  Certain balance sheet and income statement amounts in the condensed combined
pro forma financial information of Xpedite have been reclassified to conform
with the unaudited pro forma condensed combined financial information
presentation and disclosure practices of Premiere.
 
  The unaudited pro forma condensed combined financial information is presented
for illustrative purposes only and is not necessarily indicative of the
financial position or results of operations that would have actually been
reported had the acquisitions of Xpedite and XSL occurred at the beginning of
the periods presented nor is it indicative of future financial position or
results of operations. The unaudited pro forma condensed combined financial
information is based on the respective historical financial statements for
Premiere, TeleT, Xpedite and XSL and should be read in conjunction with the
respective historical financial statements incorporated by reference herein.

                NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS
 
PRO FORMA ADJUSTMENTS - THE MERGER
 
PRO FORMA ADJUSTMENTS HAVE BEEN MADE TO:
 
(A) Reflect the issuance of shares of Premiere Common Stock in exchange for all
    of the outstanding Xpedite Common Stock.
 
(B) Give effect to additional shares of Premiere common stock issued to Xpedite
    stockholders in connection with the Merger as though such shares were
    issued January 1, 1994.
 
(C) Conform Xpedite to accounting policies followed by Premiere.
 
(D) Reflect transaction expenses and restructuring and related costs (including
    severance costs, charges for asset impairment and closing certain
    facilities) to be incurred in connection with the Merger. Such costs, which
    will be incurred by both Premiere and Xpedite, are reflected as an increase
    in accumulated deficit and accrued liabilities net of income tax effects.
    The amount reflects a current estimate based on available information and
    may vary from the amounts ultimately incurred.
 
PRO FORMA ADJUSTMENTS--XSL ACQUISITION.
 
  A preliminary allocation of the purchase price of XSL is presented in the pro
forma condensed combined financial statements. A final allocation of the
purchase price to the XSL assets acquired and liabilities assumed is dependent
upon certain valuations and studies which will be performed at a future date.
While management believes that consideration in excess of the historical book
value of XSL's assets and liabilities will be primarily comprised of goodwill,
such amount may be allocated to certain research and development projects and
other intangible assets. To the extent a portion of the purchase price is
allocated to research and development projects for which technological
feasibility has not been established, a charge, which may be material to the
combined operations of Premiere and Xpedite, will be recorded in a period
subsequent to the merger of these companies. Pro forma adjustments necessary to
reflect the XSL Acquisition as though such transaction occurred effective
January 1, 1996 have been made to:
 
(E) To eliminate amounts due from XSL to Xpedite.
 
(F) To record costs in excess of fair value of net assets of XSL.
   
(G) To record payment of $85.5 million cash consideration due at closing of the
    XSL Acquisition and related fees.     
 
(H) To record the estimated fair value of XSL customer list.
 
(I) To eliminate debt issue costs on existing Xpedite debt.
 
(J) To record acquisition financing, refinancing of Xpedite's existing credit
    facility and related debt issuance costs.
 
(K) To record refinancing of Xpedite's existing credit facility and the
    elimination of existing XSL debt, preferred stock and related accrued
    dividends which were not assumed.

                             STOCK PLAN AMENDMENT
 
  Premiere's Board of Directors has adopted, subject to shareholder approval,
certain amendments (the "Stock Plan Amendments") to Premiere's Second Amended
and Restated 1995 Stock Plan (the "Plan"). These amendments propose to
increase the number of shares of Premiere Common Stock reserved for issuance
pursuant to the Plan from 4,000,000 to 8,000,000. Premiere intends to issue
options to purchase up to 2,000,000 shares of Premiere Common Stock to current
and future employees of Xpedite and individuals that Premiere plans to recruit
to join the Xpedite management team (the "Key Xpedite Employee Options"). The
Key Xpedite Employee Options will be granted at the fair market value of
Premiere Common Stock on the date of grant and generally will vest ratably
over a period of four years. This proposal is separate from and in addition to
the amendments previously adopted by the shareholders at the 1997 Annual
Meeting.
   
  The Board of Directors of Premiere believes that the Stock Plan Amendment is
needed to provide Premiere with greater flexibility to attract and retain
highly qualified employees, directors, key consultants and advisors in the
future. As of December 31, 1997, there were approximately 659,418 shares of
Premiere Common Stock available for issuance under options, SARs and
restricted stock grants (collectively, the "Awards") pursuant to Premiere's
then existing Plan. The Board believes that Premiere will need additional
shares of Premiere Common Stock available for issuance for future use.     
 
  THE FOLLOWING IS A SUMMARY OF THE PRINCIPAL FEATURES OF THE PLAN, BUT IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE PLAN SET FORTH
AS ANNEX D TO THIS JOINT PROXY STATEMENT/PROSPECTUS. PREMIERE STOCKHOLDERS ARE
URGED TO READ THE ACTUAL TEXT OF THE PLAN.
 
PURPOSE
 
  The purpose of the Plan is to advance the interests of Premiere, its
subsidiaries and shareholders by affording certain employees and directors of
and key consultants and advisors to Premiere, and its subsidiaries, an
opportunity to acquire or increase their proprietary interests in Premiere.
The objective of the Awards is to promote the growth and profitability of
Premiere by providing Award recipients an additional incentive to achieve
Premiere's objectives through participation in its success and growth and by
encouraging their continued association with or service to Premiere.
 
SHARES SUBJECT TO THE STOCK PLAN
 
  A total of 4,000,000 shares of Premiere Common Stock have been reserved for
issuance upon the exercise of options or SARs or upon the grant of restricted
stock awards under the Plan. The amendments increase the number of shares of
Premiere Common Stock reserved for issuance under the Plan from 4,000,000 to
8,000,000. If the number of outstanding shares of Premiere Common Stock are
increased or decreased or changed into or exchanged for a different number or
kind of shares or other securities of Premiere by reason of merger,
consolidation, reorganization, recapitalization, stock split or stock dividend
or other change in corporate structure, the number and type of shares shall be
adjusted appropriately by the 1995 Stock Plan Committee. If any option
terminates for any reason without having been exercised in full, or any Award
is forfeited, the shares of Premiere Common Stock not issued will then become
available for additional grants under the Plan.
 
  The Plan provides for a limitation on the number or amount of Awards which
may be issued to any one participant in a given calendar year in order to
comply with Section 162(m) of the Code. The Plan establishes 500,000 shares of
Premiere Common Stock with respect to options and SARs and $2,000,000 in fair
market value with respect to restricted stock grants as the maximum annual
limits.
 
ADMINISTRATION
 
  The Plan is administered by the 1995 Stock Plan Committee, which consists of
at least two directors appointed from time to time by the Board who are (i)
"non-employee directors," as that term is defined in Rule
 
                                      82
<PAGE>
 
16b-3 promulgated under Section 16 of the Exchange Act, and (ii) "outside
directors," as that term is defined in Section 162(m) of the Code and the
regulations promulgated thereunder. During any time that the Premiere Board is
acting as administrator of the Plan, it shall have all the powers of the 1995
Stock Plan Committee under the Plan.
 
  The 1995 Stock Plan Committee has complete authority to interpret the Plan,
to prescribe, amend and rescind rules and regulations relating to the Plan, to
determine the details and provisions of each award agreement and to make all
other determinations necessary or advisable for the administration of the
Plan. Discussions and determinations of the 1995 Stock Plan Committee shall be
binding on all persons.
 
  The 1995 Stock Plan Committee may, but is not required to, grant Awards the
benefit of which is determined solely on the basis of: (i) the achievement by
Premiere or a subsidiary of a specified target return on equity or return on
assets; (ii) Premiere's or a subsidiary's stock price; (iii) the achievement
by a business unit of Premiere or a subsidiary of a specified target net
income or earnings per share, including, without limitation, earnings before
interest, taxes, depreciation and amortization; or (iv) any combination of the
goals set forth in (i) through (iii) above. The 1995 Stock Plan Committee
shall have the right for any reason to reduce (but not increase) any Award,
notwithstanding the achievement of a specified goal. If an Award is made on
such basis, the 1995 Stock Plan Committee shall establish goals prior to the
beginning of the period for which such performance goal relates (or such later
date as may be permitted under Section 162(m) of the Code). Any payment of an
Award granted with performance goals shall be conditioned on the written
certification of the 1995 Stock Plan Committee in each case that the
performance goals and any other material conditions were satisfied.
 
AMENDMENT OF THE PLAN
 
  The Premiere Board may at any time and from time to time terminate, amend or
modify the Plan without Premiere shareholder approval; provided, however, that
the Premiere Board may condition any amendment on shareholder approval if such
approval is necessary or advisable with respect to tax, securities or other
applicable laws. No termination, amendment or modification of the Plan shall
adversely affect any previously granted Awards under the Plan without the
consent of the participant.
 
ELIGIBILITY
 
  The 1995 Stock Plan Committee may make Awards to those persons whose
participation in the Plan the 1995 Stock Plan Committee determines to be in
the best interests of Premiere. The class of persons eligible to receive
Awards includes, but is not limited to, all employees and directors of and key
consultants and advisors to Premiere and its subsidiaries. In selecting the
recipients of Awards, as well as in determining the number of shares subject
to or granted in each Award, the 1995 Stock Plan Committee takes into
consideration such factors as it deems relevant to accomplish the purpose of
the Plan.
 
TERMS OF AWARDS
 
  The terms of each Award granted under the Plan are determined by the 1995
Stock Plan Committee. Incentive stock options ("ISOs") and nonqualified stock
options ("NSOs") may be granted under the Plan, provided that only employees
of Premiere or its subsidiaries shall be eligible to receive ISOs. The
exercise price for each option will be established by the 1995 Stock Plan
Committee, provided that the exercise price of an ISO shall not be less than
the fair market value of the Premiere Common Stock on the grant date. Vested
options may be exercised at any time during the term of the option, provided
that no option which is an ISO may be exercised after ten years from the grant
date, and provided further that no option which is an ISO and which is granted
to any person owning more than 10% of the total combined voting power of all
Common Stock of Premiere outstanding on the grant date may be exercised after
five years from the grant date.
 
 
                                      83
<PAGE>
 
OTHER TYPES OF AWARDS
 
  The Plan also permits the grant of SARs and restricted stock awards. An SAR
entitles the recipient to receive the difference between the fair market value
of the Premiere Common Stock on the date of exercise and the SAR price, in
cash or in shares of Premiere Common Stock, or a combination of both, as
determined in the discretion of the 1995 Stock Plan Committee. The SAR price
will be established by the 1995 Stock Plan Committee, provided that the SAR
price must be at least 100% of the fair market value of the Premiere Common
Stock on the grant date when issued in tandem with ISOs. Restricted stock
awards entitle the recipient to receive shares of Premiere Common Stock,
subject to forfeiture restrictions that lapse over time or upon the occurrence
of events specified by the 1995 Stock Plan Committee. No SARs or restricted
stock awards have been granted.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  THE FOLLOWING DISCUSSION OF THE FEDERAL INCOME TAX CONSEQUENCES OF THE PLAN
IS INTENDED TO BE A SUMMARY OF APPLICABLE FEDERAL INCOME TAX LAW. STATE AND
LOCAL TAX CONSEQUENCES MAY DIFFER. BECAUSE THE FEDERAL INCOME TAX RULES
GOVERNING OPTIONS, SARS AND RESTRICTED STOCK AND RELATED PAYMENTS ARE COMPLEX
AND SUBJECT TO FREQUENT CHANGE, PARTICIPANTS ARE ADVISED TO CONSULT THEIR TAX
ADVISORS PRIOR TO THE EXERCISE OF OPTIONS OR SARS, OR DISPOSITIONS OF
RESTRICTED STOCK OR PREMIERE COMMON STOCK ACQUIRED PURSUANT TO AN OPTION
EXERCISE.
 
  ISOs and NSOs are treated differently for federal income tax purposes. ISOs
are intended to comply with the requirements of Section 422 and related
Sections of the Code. NSOs need not comply with such requirements.
 
  A participant is not taxed on the grant of an NSO. Upon exercise, however,
the participant recognizes ordinary income equal to the difference between the
exercise price and the fair market value of the shares on the date of the
exercise. Premiere is entitled to an income tax deduction in the year of
exercise in the amount recognized by the participant as ordinary income. Any
gain on subsequent disposition of the shares is long-term capital gain if the
shares are held for at least one year following exercise. Premiere does not
receive an income tax deduction for this gain.
 
  A participant is not taxed on the grant or exercise of an ISO. The
difference between the fair market value of the shares on the exercise date
will, however, be a preference item for purposes of the alternative minimum
tax. If a participant holds the shares acquired upon exercise of an ISO for at
least two years following grant and at least one year following exercise, the
participant's gain, if any, on a subsequent disposition of such shares will be
treated as long-term capital gain for federal income tax purposes. The measure
of the gain is the difference between the proceeds received on disposition and
the participant's basis in the shares (which generally equals the exercise
price). If the participant disposes of stock acquired pursuant to the exercise
of an ISO before satisfying the one- and two-year holding periods described
above, the participant will recognize both ordinary income and capital gain in
the year of disposition. The amount of the ordinary income will be the lesser
of: (i) the amount realized on disposition less the participant's adjusted
basis in the stock (usually the exercise price); or (ii) the difference
between the fair market value of the stock on the exercise date and the
exercise price. The balance of the consideration received on such disposition
will be long-term capital gain if the stock had been held for at least one
year following exercise of the ISO. Premiere is not entitled to an income tax
deduction on the grant or the exercise of an ISO or on the participant's
disposition of the shares after satisfying the holding period requirement
described above. If the holding periods are not satisfied, Premiere will be
entitled to an income tax deduction in the year the participant disposes of
the shares, in an amount equal to the ordinary income recognized by the
participant.
 
  Recipients of SARs do not recognize income upon the grant of such rights.
When a participant receives or is deemed under applicable tax rules to have
received payment of an SAR, the participant recognizes ordinary
 
                                      84
<PAGE>
 
income in the amount equal to the cash and/or fair market value of shares of
Premiere Common Stock to which the SAR relates, and Premiere is entitled to an
income tax deduction equal to such amount.
 
  Unless a recipient of a restricted stock award makes an election to
accelerate recognition of income to the grant date, the participant will not
recognize income upon the grant of the restricted stock award. When the
restrictions are deemed to have lapsed under applicable tax rules, the
participant recognizes ordinary income in an amount equal to the fair market
value of shares of Common Stock to which the restricted stock award relates,
and Premiere is entitled to an income tax deduction equal to such amount.
 
BENEFITS TO NAMED EXECUTIVE OFFICERS AND OTHERS
   
  The following table sets forth the options granted under the 1995 Stock Plan
as of December 31, 1997. The 1995 Stock Plan Committee has not yet made any

                          DESCRIPTION OF XPEDITE     
 
OVERVIEW
 
  Xpedite is a worldwide leader and innovator in the enhanced fax services
business and also provides discounted fax, e-mail, telex, Internet and
mailgram services. Xpedite serves customers who require high-quality, cost-
effective, rapid, and confirmed communications. Xpedite has developed
sophisticated applications in a wide range of industries that enable customers
to deliver common or customized documents to hundreds or thousands of
recipients around the world via fax or electronic mail using Xpedite's
proprietary, private, world-wide document distribution network (the "Xpedite
Network").
   
  Based in Eatontown, New Jersey, Xpedite delivers its document distribution
services over the Xpedite Network, with POPs in over 70 cities in
approximately 29 countries around the world. The Xpedite Network includes over
14,500 dedicated lines in addition to complete Internet access and
compatibility to allow for the ability to receive and deliver messages in
whatever format is optimal to ensure timely delivery.     
 
STRATEGY
   
  In 1988, Xpedite was formed and began marketing enhanced fax and messaging
delivery services ("Enhanced Services"). From its inception, Xpedite's focus
was on the provision of value-added fax services consisting primarily of "fax
broadcast" and "gateway messaging" services in the U.S. market. Xpedite
strives to build value-added relationships with its customers through a sales
force of 273 employees working from 50 sales offices in 13 countries. Fax
broadcast allows a single document to be faxed to multiple recipients through
a single transmission to the Xpedite Network, while gateway messaging provides
high volume transmission of individual documents, each of which is in the same
format, but contains customized information. Xpedite's Enhanced Services
provide customers with rapid, cost-effective delivery of documents worldwide.
Xpedite's strategy consists of three elements:     
 
    (i) identifying new applications for Xpedite's fax services and offering
  messaging capabilities beyond fax (e.g., telex and electronic mail);
 
    (ii) expanding Xpedite's service business internationally through the
  establishment of service bureaus around the world; and
 
    (iii) adding new services to Xpedite's products mix and leveraging
  Xpedite's sales force as the Enhanced Services business grew and justified
  domestic and international networks.
 
  The execution of this strategy continues to involve expanding Xpedite's
sales force, completing strategic acquisitions, continuously developing the
enhanced messaging services platform and leveraging the existing Xpedite
Network. For example, Xpedite's second major product offering utilizes the
existing Xpedite Network to provide discounted international messaging
services ("Discounted International Services") which provide real-time and
delayed transmission of documents over the Xpedite Network at significant
savings to Xpedite's customers.
 
  By expanding its sales organization and developing new applications for its
services, Xpedite has become the largest provider of Enhanced Services in the
United States and now offers these services throughout North America, Europe
and the Pacific Rim. Xpedite believes that significant opportunities exist for
continued development in international markets. One strategy for international
expansion involves marketing applications which are established and widely
used in the United States but which are only in the early stages of adoption
overseas. Xpedite's sales force continues to identify new applications as well
as to further customize and market established applications. In addition,
Xpedite's ability to leverage (i) its solution-oriented sales force by
developing new and cost-effective document distribution solutions that
stimulate market demand, and (ii) its network infrastructure through growth in
fax traffic resulting from existing applications, new applications and new
products, creates what Xpedite believes is a platform for profitable worldwide
growth. To further stimulate market demand, Xpedite has, to date, passed a
portion of these benefits to customers through the form of price reductions.
 
                                      86
<PAGE>
 
  Xpedite's current strategy is to expand from being primarily a provider of
Enhanced Services in North America to become a provider of both Enhanced
Services and Discounted International Services worldwide and to continue to
integrate multiple transmission approaches like fax, Internet and e-mail in
unique ways to meet its customers' needs. The key elements of Xpedite's
strategic plan are to:
 
    (i) leverage its proven experience in the Enhanced Services market by
  continuing to develop new applications for the Enhanced Services and by
  establishing a leadership position in new markets through "exporting"
  proven Enhanced Services to geographic areas in which Xpedite has not
  historically offered such services;
 
    (ii) capitalize on the multi-billion dollar market for Discounted
  International Services by aggressively marketing both its "store-and-
  forward" and "real-time" services through its direct sales force, sales
  agents, resellers and Nodal Partners (as defined herein), and by installing
  the infrastructure required for the delivery of such services on a
  worldwide basis;
 
    (iii) continue to expand and develop its solution-oriented direct sales
  force, which Xpedite believes is one of the key factors for its success;
 
    (iv) develop and/or acquire additional technologies and applications to
  expand Xpedite's messaging capabilities and leverage its sales force and
  market presence;
 
    (v) expand the Xpedite Network by adding new geographic points of
  presence ("Nodes") and leased telecommunications lines in order to continue
  to lower its fax delivery costs; and
 
    (vi) increase market share, expand geographic coverage, leverage the
  Xpedite Network and achieve economies of scale through strategic alliances
  and other business relationships.
 
PRODUCTS AND SERVICES
 
  Xpedite's services provide customers with a lower cost, more reliable and
more time efficient information delivery method than most other document
distribution alternatives. Xpedite's Enhanced Services consist primarily of
its "fax broadcast" and "gateway messaging" services. Fax broadcast services
enable a customer to rapidly distribute the same document to multiple
recipients by sending a single transmission through Xpedite's system to a list
of fax addresses. The appeal of the fax broadcast service is the significant
cost and time savings as compared to internally printing and mailing documents
or managing the fax process. Examples of the types of communications delivered
via fax broadcast services include the dissemination of research reports by
financial services organizations and the transmission of campaign information
by political groups. In addition, a portion of Xpedite's fax broadcast
revenues are attributable to customers utilizing Xpedite's proprietary "PC
Xpedite" software, which enables a customer to input the document to be
broadcast and transmit it to Xpedite, and supports the customer's capability
to maintain lists of fax addresses. Gateway messaging, Xpedite's other primary
Enhanced Service, enables a customer to send information from the customer's
computer through Xpedite's system to a recipient's fax or telex machine, or to
a recipient via the Internet or X.400 electronic mail networks or other
electronic media. Xpedite's gateway messaging service typically involves the
processing of a large volume of individual communications (i.e., a single
document to a single recipient or from a single sender), each of which is in
the same format but contains different information. Examples of the types of
communications delivered via gateway messaging services include the delivery
of confirmations of reservations by hotels and airlines and the delivery of
invoices, purchase orders and shipping documents by manufacturing and shipping
companies.
 
  In connection with its Enhanced Services, Xpedite offers a number of
applications that Xpedite believes increases the attractiveness of its
products and differentiates Xpedite in the marketplace. Examples of these
applications include: (i) "Fax on Demand" which allows callers to select
information using a touch tone phone and to have such information sent
directly to their fax machine; (ii) "Enhanced Fax Merging" which permits
senders to personalize information which can be inserted into original text at
any point in a standard multi-address document; and (iii) "Toll-Free Fax
Response" which allows senders to receive responses by fax to a toll-free 800
number.
 
 
                                      87
<PAGE>
 
  Xpedite's Discounted International Services allow a customer to use an
automatic dialing device attached to the customer's fax machine (at a cost of
less than $100) to direct international faxes to the Xpedite Network for
delivery to the recipient at a discount of approximately 15% to 25% to
standard international toll calls. Xpedite's initial Discounted International
Service was a "store-and-forward" service, in which the fax is transmitted by
the sender and stored in Xpedite's system for subsequent delivery. In response
to demand in the market for a discounted international fax service that would
enable the sender to obtain immediate confirmation that the fax had been
delivered, Xpedite launched its "real-time" service in the second half of
1996. With real-time service, the customer uses the same automatic dialing
device as is used in the store-and-forward service, but rather than store the
fax for subsequent delivery, Xpedite connects the sender's fax machine
directly to the recipient's fax machine, thereby delivering the fax
immediately.
 
CUSTOMER BASE
 
  Xpedite has achieved significant growth in its customer base. Applications
for Xpedite's messaging services are utilized by a broad array of customers
including those in the publishing, public relations and investor relations,
commercial banking, manufacturing, travel, electronics, legal and
pharmaceutical industries. Xpedite's international network and capacities have
also attracted customers from additional industries such as the global freight
industry. Xpedite's customer base is broadly diversified, with no single
domestic industry group accounting for greater than 15% of revenues. Xpedite
believes that this diversification limits its susceptibility to the
cyclicality of any particular industry or a general business downturn in any
particular sector.
 
SALES AND MARKETING
   
  Xpedite's business has grown as a result of, among other things, the
development of a highly-trained sales organization. In selling Enhanced
Services, Xpedite's sales force is trained to identify the issues surrounding
a specific industry sector and consult and educate its clients to create the
optimal solution for the clients' needs. Technically competent sales people
are required to market and implement Xpedite's product due to the "problem
solving" or "solution-oriented" nature of the selling strategy. In addition,
through the launch of Xpedite's real time service, Xpedite's global sales
force has exhibited the ability to successfully and quickly implement the sale
of new products and services. Xpedite's full-time direct sales force has
increased from 41 people at the end of 1992 to 273 people as of December 31,
1997. These full-time sales personnel are deployed throughout Xpedite's 50
sales offices in 13 countries today with approximately 171 operating in North
America. Xpedite also utilizes a significant network of third party
distributors (sales agents and resellers) both in countries where it has a
direct sales presence and in locations where it does not currently have such a
presence. These third party distributors accounted for approximately 20% of
Xpedite's net revenues in 1996.     
 
THE XPEDITE NETWORK
   
  In order to offer high quality Enhanced Services and Discounted
International Services in a cost efficient manner, Xpedite has established the
Xpedite Network. The Xpedite Network is able to serve the electronic messaging
needs of its customers through the use of proprietary software and a document
distribution system network of over 14,500 leased telecommunications lines and
its "Nodal Partners." "Nodal Partners" are independent entities that have
purchased an electronic document distribution system from Xpedite and which
sell Discounted International Services. A "Node" is an element of the Xpedite
Network located at a geographically distinct "point of presence" that allows
access to or egress from the Xpedite Network via a local call.     
   
  The proprietary network software that has been developed by Xpedite allows
its Enhanced Services customers access to the Xpedite Network via several
communications options including fax machines, the Internet, mainframe or mini
computers, and Local Area Networks ("LANs"). Customers who use fax machines to
access the Xpedite Network for Enhanced Services or Discounted International
Services are connected to the Xpedite Network through an "autodialer," which
routes the document over a lower-cost telecommunications line leased by
Xpedite.     
 
                                      88

  The low-cost structure of the Xpedite Network is achieved through the use of
leased telecommunications lines and Nodal Partners which allow Xpedite to
transmit a greater number of faxes through inexpensive local calls rather than
high priced long distance or international calls. The Xpedite Network is
intended to provide Xpedite's Enhanced Services and Discounted International
Services customers with a reliable alternative for long distance and
international document distribution at significant price discounts and cost
savings, particularly in overseas telecommunications markets that are highly
regulated and have limited competition. As it increases fax messaging traffic
over the Xpedite Network, Xpedite is able to exploit economies of scale which
result in lower costs per minute or per page and then pass a portion of these
cost savings on to customers, further stimulating demand for Xpedite's
services.
 
  Xpedite charges for its fax services both on a per minute and a per page
basis, with the bulk of its sales occurring on a per minute basis. A
substantial portion of Xpedite's fax traffic terminates in cities where
Xpedite or its affiliates have Nodes. Xpedite estimates that approximately 40%
of its domestic fax deliveries in 1996 were routed over the Xpedite Network.
Xpedite purchases long-distance services from MCI, Cable & Wireless LDDS
(WorldCom) and a number of PTTs around the world, among others, to carry fax
traffic that is routed to destinations where Xpedite does not have Nodes. In
the future, Xpedite expects its total telecommunications costs per minute of
fax traffic to decrease as an increasing amount of traffic is routed over the
Xpedite Network.
 
COMPETITION
 
  Xpedite competes based on a number of factors, such as customer service and
support, service features and price. Of these factors, Xpedite believes that
service and support are the most important for Enhanced Services, while price
is the critical competitive component with respect to Discounted International
Services in developed countries with high quality long distance networks. In a
service industry in which a broad range of optional features are offered,
Xpedite's competitive strategy emphasizes a sales and support network that is
well-versed in the capabilities of the services offered to customers. Xpedite
believes that, while it continues to expand its development activity in order
to add a broad range of features to its services, it is the focus of its sales
and support organizations on customers' needs that enables Xpedite to compete
effectively.
 
  AT&T, MCI and Sprint, as well as other long distance carriers, Internet
Services Providers ("ISPs") and national PTTs, provide certain fax
communications services in competition with Xpedite. Xpedite believes it can
compete effectively with its competitors because of its focus on the fax
communications services market, its broad array of service features and its
cost-effective worldwide Xpedite Network. Particularly in the market for basic
fax services, Xpedite believes that by using the Xpedite Network it can offer
high quality service to customers at rates lower than those available from
other carriers, such as PTTs, which have historically dominated this market,
but typically provide telecommunications services at regulated rates that may
be significantly greater than the underlying cost of the transmission. In
addition, Xpedite believes that, while AT&T and Sprint have begun to expand
the number of international Nodes employed by them, they have not committed to
the direct deployment of targeted sales personnel to focus on the
international fax markets, and that AT&T and Sprint currently are relying
primarily on worldwide partners and agents in marketing their fax services
outside of the United States.
 
  In addition to the long distance carriers, ISPs and PTTs, Xpedite competes
with a number of service bureaus based on the factors described above. Many
service bureaus face considerable obstacles in developing a business
competitive with Xpedite's. While it may be easy to begin service with a small
personal computer-based system, considerable system development expenditures
are required to enable such a system to grow to support the volumes and
features needed to be an effective competitor in the marketplace. Further, a
small service bureau typically will not have a sufficient volume of traffic to
develop the economic leverage necessary to obtain telecommunications services
at rates enabling it to compete cost-effectively with Xpedite. In addition,
considerable investment in a sales and marketing organization is required to
develop a substantial business base. As a result of the Xpedite's investment
in its sales and marketing organization, Xpedite believes that the size of its
sales force significantly exceeds that of any service bureau in the United
States, and Xpedite knows of no other service bureau with as many sales
personnel and Nodes in as many countries as Xpedite.

  As of October 1, 1997, Xpedite had approximately 13,500 telecommunication
lines dedicated to fax transmission, which Xpedite believes was more than
twice as many dedicated lines as its nearest competitor. Xpedite intends to
continue to add dedicated lines as its volume of fax transmissions makes the
installation of such lines cost effective to support the growth of Xpedite's
business.
 
  Xpedite believes that its major advantages in addressing the international
market is that it is offering its services and already has operating centers
and full time sales personnel in the major telecommunications centers around
the world, and that its network of Nodal Partners extends this presence beyond
such major centers. Another major advantage is that Xpedite's basic fax
services include both real-time and store and forward options, while Xpedite's
competitors may only offer one of such options.
 
  Another alternative to using Xpedite's services is for a potential customer
to fulfill its own needs for fax communications services. The "home grown"
solution may simply be an individual at a fax machine or may involve the
customer acquiring its own computerized fax communications system (sometimes
known as "customer premise equipment" or "CPE"). Xpedite believes that the CPE
solution is suitable in some applications, but is generally not feasible for
Xpedite's customers, who require the capacity to effect a significant volume
of electronic document deliveries in a short period of time. Xpedite believes
that the CPE solution for a fax broadcast application would require the
customer to obtain and maintain a large number of telephone transmission lines
which would remain idle for significant periods of time. Further, for
international fax traffic, the customer would be required to set up a
worldwide nodal network; Xpedite believes that this is only practical for
large multinational firms and even these firms would be unlikely to develop a
network which would reach as many countries as the Xpedite Network. As a fax
communications services provider with many customers, Xpedite is able to
spread the costs of operating the Xpedite Network over a large number of
users. In addition to being concerned with the irregular nature of demand, a
customer selecting a CPE solution must consider the total cost of system
acquisition, ongoing technical support, reliability, technological
obsolescence and accountability. Based on the foregoing, Xpedite believes that
a substantial percentage of customers in the market for fax communications
services will elect a service provider rather than CPE. In fact, as Xpedite's
prices have fallen over time in the United States, a number of customers who
tried to implement CPE solutions have returned as service customers.
 
  Similarly, delivery of electronic information via the Internet provides an
alternative to Xpedite's fax services. However, Internet delivery does not
offer prompt confirmation of receipt of information in "real time" and has the
additional risks of limited security and confidentiality of information
delivered over a worldwide network easily accessed by third parties. Finally,
while a fax transmission alerts the recipient that information has been
delivered, information delivered via e-mail often relies on the recipient
inquiring whether information has been delivered. Delivery by the Internet
cannot be an alternative if a sender or recipient of information does not have
access to the Internet. Xpedite currently has the capability to deliver
information using the Internet and utilizes this network both as an optional
access vehicle to its services and as an e-mail delivery vehicle. Xpedite may
expand the use of these features as business users increase their reliance on
the Internet.
 
EMPLOYEES
   
  Xpedite considers its relationship with its employees to be satisfactory.
Xpedite employed 763 persons as of December 31, 1997, substantially all of
whom were full-time employees, and none of whom was covered by a collective
bargaining arrangement. Of these employees, 427 were engaged in sales and
marketing; 208 in operations; 51 in research and development; and 77 in
general and administrative activities. Approximately 30% of Xpedite's
employees are located in Xpedite's Eatontown, New Jersey headquarters; none of
Xpedite's remaining offices employs more than 10% of Xpedite's employees.     
 
PROPERTIES
   
  Xpedite's headquarters facility, which includes its principal
administrative, sales, marketing, management information systems and product
development offices and its operations center is located in approximately
49,000     
 
                                      90
<PAGE>
 
square feet of leased space in Eatontown, New Jersey. The lease on this
facility terminates on September 30, 1998 (excluding a five-year renewal
option exercisable by Xpedite ). Xpedite also maintains a development
facility, located in approximately 9,000 square feet of leased space, in Ft.
Lauderdale, Florida. The lease on this facility expires December 31, 2001.
Xpedite owns an office building located in London, consisting of approximately
4,000 square feet of office space.
 
  Xpedite also maintains approximately 20,000 square feet of leased space for
the principal administrative, sales, and management information systems
offices and operations center of its international division in Glen Head, New
York. The lease covering approximately 75% of this space expires on December
30, 1999, and the lease covering the remaining space expires on September 30,
2001, subject, in each case, to extension or earlier termination in certain
circumstances.
 
  Since 1994, Xpedite has leased approximately 4,900 square feet of space in a
Piscataway, New Jersey facility, where Xpedite has established an additional
operations center which is substantially identical, in terms of capability, to
its current operations center at its headquarters in Eatontown, New Jersey.
This facility provides Xpedite with another level of protection in its
operational systems, and is expected to enable Xpedite to continue its
operations in the event of a disaster at either facility. The lease on this
facility terminates February 28, 2001. The additional facility is designed to
enable Xpedite to more easily expand its systems, will provide additional
processing and transmission capacity and will be linked with Xpedite's
facilities at its headquarters. As of December 31, 1996, Xpedite has invested
approximately $0.9 million establishing this facility.
   
  As of December 31, 1997, Xpedite leased an additional 32 sales and support
offices across the United States and Canada, consisting of approximately
36,000 square feet in the aggregate, pursuant to the terms of various short-
term lease agreements. Xpedite also leased 17 sales and support offices in
other countries around the world, consisting of approximately 30,000 square
feet in the aggregate, pursuant to the terms of various short-term lease
agreements. Xpedite believes that its existing facilities are adequate to meet
current requirements and that suitable additional space in close proximity to
its existing headquarters will be available as needed to accommodate growth of
its operations and additional sales and support offices through the
foreseeable future.     
 
STRATEGIC RELATIONSHIPS AND ACQUISITIONS
   
  To complement its internal sales growth and expand internationally, Xpedite
has completed eight acquisitions since 1993. In February 1993, Xpedite
acquired certain enhanced fax and messaging services assets from TRT/FTC
Communications, Inc. In November 1995, Xpedite acquired the SVC Companies,
which together had POPs in 35 countries and a 45 person direct sales force.
The acquisition of the SVC Companies significantly expanded Xpedite's North
American and international businesses and allowed Xpedite to accelerate its
entry into the international fax market. On a pro forma basis, the acquisition
of the SVC Companies, which had revenues of over $55 million in 1995,
approximately doubled Xpedite's net revenues for the year ended December 31,
1995. More recently, Xpedite continued its expansion in the Pacific Rim
through (i) the acquisition in September 1996 of the fax service business of
PosData Company Ltd., Xpedite's Nodal Partner in South Korea, (ii) the
acquisition in December 1996 of the enhanced fax service business of PacStar,
known as Fax 2000, an Australian fax service provider, and (iii) the
establishment in early 1997 of a 50%-owned joint venture which offers message
delivery services in Singapore.     
   
  In connection with its international expansion, Xpedite has also entered
into relationships with each of XSL, Xpedite Germany and Xpedite Systems SA,
(collectively the "European Affiliates.") At the time of formation of each of
these entities, Xpedite entered into a System and Marketing Agreement and a
Put and Call Option Agreement (collectively, the "Put/Call Agreements") with
each European Affiliate and, in the case of the Put/Call Agreements, each
affiliate's shareholders. These agreements provided for the sale by Xpedite to
each European Affiliate of Xpedite's document distribution system, along with
a license to the software used to operate such system (for which the European
Affiliate pays royalties on a declining percentage basis), joint marketing
efforts, and put and call rights which, upon the achievement of specified
levels of financial     
 
                                      91
<PAGE>
 
   
performance by the relevant European Affiliate and fulfillment of certain other
conditions, would enable or require Xpedite to purchase interests in the
relevant European Affiliate.     
   
  In December 1997, XSL Acquisition Corp. purchased all the share capital of
XSL for a purchase price of approximately $85.5 million. Pursuant to the XSL
Purchase Agreement, the Put/Call Agreement with respect to XSL has been
terminated. In January 1998, Xpedite acquired, directly or indirectly,
approximately 76.7% of the issued share capital of Xpedite Germany and
indebtedness of Xpedite Germany to its former majority shareholder for an
aggregate purchase price of approximately $13.2 million. Together with the
19.9% of the issued share capital of Xpedite Germany previously owned by
Xpedite, Xpedite currently owns approximately 96.6% of the issued share capital
of Xpedite Germany. In addition, Xpedite has an option to purchase the
remaining 3.4% of the issued share capital of Xpedite Germany, exercisable at
any time after February 15, 1998, at a purchase price of approximately
$600,000. Pursuant to the Xpedite Germany Purchase Agreements, the Put/Call
Agreement with respect to Xpedite Germany has been terminated.     
       
       
DESCRIPTION OF XSL'S BUSINESS
 
  General. XSL is a leading provider of Enhanced Services in the United
Kingdom. To capitalize on the market need for the provision of Enhanced
Services, XSL was formed as a start-up company in January 1993 by certain
members of XSL's management and the APAX Funds. The APAX Funds currently own
approximately 75% of XSL's outstanding share capital, a United Kingdom bank
owns approximately 0.5%, and the remainder of such outstanding share capital is
held by XSL's management. Through internal growth and strategic acquisitions,
XSL has significantly improved its financial performance since its formation.
For the six months ended June 30, 1997, net revenues increased 24% to
(Pounds)9.8 million, EBITDA increased 121% to (Pounds)4.5 million and net
income increased 89.8% to (Pounds)2.8 million as compared to the same period in
1996. For the fiscal year ended December 31, 1996, net revenues increased 139%
to (Pounds)16.3 million, EBITDA increased from (Pounds)0.6 million to
(Pounds)5.2 million and net income increased to (Pounds)3.4 million from a loss
of (Pounds)0.3 million in the prior year. For the fiscal year ended December
31, 1995, net revenues increased 497% to (Pounds)6.8 million, EBITDA increased
(Pounds)0.2 million from a loss of (Pounds)0.6 million and net loss decreased
from (Pounds)0.7 million to (Pounds)0.3 million from the prior year. Excluding
acquisitions, XSL "same store" revenues grew 262% to (Pounds)15.9 million in
1996 from (Pounds)4.4 million in 1995. The historical audited consolidated
financial statements of XSL for each of the three fiscal years ended December
31, 1996 and the unaudited consolidated statements for the six months ended
June 30, 1997 and 1996 and the related notes thereto are incorporated by
reference herein. See "Available Information" and "Incorporation of Certain
Information by Reference."
 
  Based in York, England, XSL primarily provides to the U.K. market fax
broadcast and gateway messaging services similar to those provided by Xpedite
via XSL's network with points of presence in five cities located in three
countries and approximately 1,000 fax lines. XSL's customer base has
historically been concentrated in the U.K. financial sector where XSL has a
significant market share.
 
  Products and Services. XSL currently provides a wide range of Enhanced
Services. XSL's offering of fax broadcast and gateway messaging services is
substantially similar to those offered by the Company with the exception that
XSL does not offer certain specialty fax broadcast services such as Xpedite's
"Enhanced Fax Merging" service. Gateway messaging services accounted for
approximately 5% of XSL's net revenues in 1996.
 
  Approximately 68% of XSL's revenues for the year ended December 31, 1996 were
generated by customers in the financial services industry. Accordingly, a
downturn in this industry could have a material adverse impact on XSL's
business.
 
  The XSL Network. Since January 1993, XSL and Xpedite have been party to a
System and Marketing Agreement (the "System and Marketing Agreement") whereby,
among other things, XSL agreed to purchase Xpedite's document distribution
system and license Xpedite's software (for which XSL pays royalties to Xpedite
of approximately 8% of XSL's net revenues until December 31, 1998 and 6%
thereafter). As a result, XSL's
 
                                       92

<PAGE>
 
network architecture essentially mirrors Xpedite's architecture. The main
operations center and system resides in York, England with remote delivery
capability in Leeds, London, Milan, Zurich and Geneva, all linked by XSL-leased
private circuits. XSL's system is then interconnected with the networks and
systems of Xpedite, Xpedite Germany and XSSA via private circuits owned by
Xpedite, Xpedite Germany and XSSA. Currently XSL has over 1,000 outbound
telephone lines operational in the U.K. and has a dual carrier strategy in the
U.K. to provide enhanced fault protection.
 
  A substantial portion of XSL's fax traffic terminates in major capital cities
where XSL or its affiliates have Nodes. XSL purchases its telecommunications
services in the U.K. primarily from two carriers. In 1996, approximately
(Pounds)6.9 million of the total (Pounds)8.9 million cost of sales related to
telecommunications costs with another (Pounds)0.2 million relating to XSL
network costs.
 
  Sales and Marketing. Direct sales by XSL's sales personnel accounted for more
than 90% of XSL's net revenues in 1996. As of June 30, 1997, XSL employed an
15-member sales force.
 
  In addition to XSL's direct sales force, indirect sales are made through
sales agents and resellers. While indirect sales were not a significant
component of XSL's sales efforts in prior years, it is becoming an increasing
focus of XSL's sales program. Sales agents accounted for approximately 7% of
XSL's net revenues in 1996 with resellers representing the remaining 3%.
 
  Strategic Acquisitions and Relationships. Another component of XSL's recent
growth has been through two several strategic acquisitions completed by XSL. In
July 1995, XSL acquired Transmit International Ltd. ("Transmit"), and in March
1996 it acquired Connaught Commercial Services Ltd. ("Connaught"). Both
businesses consisted entirely of fax broadcast services. The customer bases
from both of these acquisitions have been migrated to XSL's network and both of
the acquired businesses' U.K. operations have been closed down.
 
  In addition, XSL has entered into a number of agreements with U.K. companies
which are primarily systems integrators to provide computer to fax capabilities
utilizing the XSL network.
 
  Competition. The market for Enhanced Services in the United Kingdom has
consolidated over the last three years, in part due to the acquisition by XSL
of Transmit and Connaught and the acquisition by Xpedite of the SVC Companies.
The market for Enhanced Services in the United Kingdom is less mature than in
the United States and is comprised principally of XSL and several domestic ad
international voice carriers, including British Telecommunications plc, Cable &
Wireless and Sprint.
 
  There are a number of smaller, independent operators competing in the UK
market, but XSL believes that none of these smaller operators currently has the
installed infrastructure to provide the options and features or to offer
customer service comparable to XSL.
 
  Employees. As of June 30, 1997, XSL employed 70 individuals. None of the
employees are represented by a union or subject to a collective bargaining
agreement. XSL considers its relations with its employees to be satisfactory.
 
  Properties. In early 1997, XSL completed the purchase of a two-story building
in York, England consisting of 13,000 square feet in which XSL's headquarters
are located.
   
  XSL also leases a self-contained facility within a multi-occupancy building
in the City of London consisting of 2,005 square feet on a lease which expires
in November 2002 on an annual rental of (Pounds)46,000. XSL also leases 3,000
square feet of offices in York, England on a lease due to expire in May 1999.
Currently, XSL subleases 1,500 square feet.

                         DESCRIPTION OF PREMIERE     
 
OVERVIEW
 
  Premiere designs, develops, markets and provides enhanced personal
communications services. Premiere's network-based computer telephony
technology links together two or more stand-alone communications services,
such as calling card long distance, voice mail, e-mail, fax mail and paging,
and allows access to these services through telephones or computers. Premiere
bundles these stand-alone services to allow users to store, manage,
prioritize, deliver and distribute incoming and outgoing information in an
easy, efficient and economical manner. Although Premiere offers stand-alone
communications services, it primarily targets users who have multiple
communications devices and a need to integrate them for greater functionality
and convenience.
   
  Today, many stand-alone communications services are provided through legacy
systems, including landline telephone systems, messaging devices and LANs,
that reside in whole or in part at a customer's location. The architecture of
the customer premises equipment, or "CPE," that comprises such systems is
often closed in nature, which makes integration with other systems and
networks difficult and expensive. However, users are increasingly demanding
that their existing CPE be integrated with more open and intelligent worldwide
communications networks such as the Internet. Premiere believes that, due to
the complexity of such integration, users will increasingly outsource their
communications requirements to third parties such as Premiere. Premiere
believes that customers will prefer Premiere's network-based service solution
for personal communications to traditional CPE-based product solutions because
Premiere's solution reduces customers' costs of equipment ownership and
exposure to technology obsolescence.     
   
  The core of the Premiere solution is its "intelligent network" which links,
or integrates, stand-alone communications services using technology developed
by Premiere's research and development team. The intelligent network consists
of (i) a state-of-the-art proprietary platform that integrates digital
switching technology with enhanced personal communications features and (ii)
Premiere's private telecommunications network which transmits voice and data
utilizing the frame relay packet switching protocol, the "private frame relay
network." Premiere's modular and scaleable intelligent network incorporates an
open-system design, which allows Premiere to easily expand capacity and
provides Premiere with the flexibility to develop and customize its service
offerings. Premiere offers bundled services in a variety of packages and
tailors these packages to meet the requirements of strategic marketing and co-
brand partners. Premiere's private frame relay network, with approximately 210
POPs is accessible via local access in metropolitan and other geographic areas
which include approximately 90% of the United States, Canadian and Australian
populations and approximately 50% of the New Zealand population. Premiere
anticipates that its private frame relay network will be accessible via local
access by a significant portion of the U.K. population in the near future.
Premiere plans to invest $40-$50 million in capital expenditures over the next
12 months as part of its effort to integrate its proprietary platform with its
recently acquired private frame relay network. Once integration is completed,
Premiere believes that its intelligent network will allow Premiere to offer
its customers enhanced personal communications services through either local
or 800 access via telephone or computer.     
   
  Premiere currently markets its services: (i) directly under the Premiere
WorldLink, Voice-Tel, VoiceCom and VoiceCom Access One names; (ii) indirectly
through strategic partners such as American Express and CompuServe; (iii)
indirectly through co-brand relationships with companies such as First Union
National Bank of Georgia ("First Union"), and Discover Card Services, Inc.
("Discover Card") and others; and (iv) indirectly through licensing or
wholesale arrangements with companies including WorldCom, NationsBanc
Services, Inc. ("NationsBank"), an affiliate of NationsBank Corporation,
UniDial Communications, Inc. ("UniDial") and Cincinnati Bell Long Distance.
Although Premiere has historically focused its direct marketing efforts on
print advertising and direct mailings targeted at mobile professionals,
Premiere recently acquired a nationwide direct sales force with a national
accounts program.

CUSTOMER CASE STUDIES
 
  Some examples of Premiere's enhanced personal communications services, which
illustrate the convenience of and benefits provided by Premiere's technology
innovations and intelligent network, include the following:
 
  E-mail Over the Phone. A consultant calls in to hear her voice mail
messages. During the same call, she can have her e-mail messages read to her
over the phone via Premiere's text-to-speech technology and save, delete,
forward or return all of her e-mail messages using one of a list of
preprogrammed responses.
 
  Personal Assistant Services. A field salesperson presents a bid to a project
approval committee. After submitting her proposal, she leaves for her next
meeting. Upon review of the proposal, the committee notices several issues
that need immediate clarification. Rather than trying to track down the
salesperson at multiple locations, the committee calls her personal assistant
number, which automatically locates her by pager, which she had designated as
her preferred method of contact on that day. If she has selected the "call
connect" feature, she can call the Premiere platform and automatically be
connected to the committee's incoming call.
   
  Premiere's Orchestrate product, which Premiere intends to begin marketing
during the first quarter of 1998, is expected to offer the following
additional features:     
 
  Universal Inbox. A busy executive can go to any Internet browser-enabled
computer to check all of his messages--voice mail, e-mail and fax mail. After
looking at a list of incoming voice and text messages, he can choose which
messages to hear or read. He can then choose to save, delete, forward or
return his messages.
 
  Click "n' Call Conference Calling. A manager with employees in eight
different offices holds weekly staff meetings by conference call. Rather than
going through the time and expense of arranging for a conference bridge with
an outside supplier, he is able to go to his computer, click on his contact
database list with his mouse and initiate the conference call without ever
picking up a telephone. After initiating the conference call, the manager
simply answers the call that the Premiere platform places to his telephone,
enters his account and PIN numbers and presses the "star" key to command the
Premiere platform to add additional parties sequentially. In the future,
features are expected to include muting and addition and deletion of selected
callers.
 
STRATEGY
 
  Premiere's goal is to become the world's leading provider of network-based
enhanced personal communications services. Premiere's strategy to achieve this
goal is to:
 
  Increase Service Offerings and Cross-Media Functionality. Premiere believes
that changes in technology continually create new business opportunities for
providers of enhanced personal communications services. Premiere continually
strives to make its interfaces more user friendly and its services
functionally equivalent regardless of the customer's chosen access device or
message transport medium. For example, Premiere has introduced such features
as text-to-speech e-mail delivery, a unified messaging interface utilizing the
World Wide Web ("Web") and an integrated Web-based contact database manager.
Possible future service features include, among others, speech recognition.
   
  Leverage Network Facilities. To date, the majority of Premiere's services
have been accessed by 800 toll free service. Premiere recently acquired an
international private frame relay network. Once this network is fully
integrated with Premiere's proprietary platform, Premiere plans to use the
private frame relay network and local messaging systems to provide users local
access to certain of its enhanced personal communications services, which
access Premiere believes will make these services more attractive to a broader
market. In addition, through transitioning more of its subscribers to local
access, Premiere expects to realize a reduction in transmission costs.     
 
  Expand Customer Base and Distribution Channels. Premiere believes that an
increasing number of businesses will transition their communications systems
from CPE-based products to network-based services. Premiere believes that a
substantial opportunity exists to meet the outsourcing needs of these
companies.
 
                                      95
<PAGE>
 
Premiere intends to use its direct sales force and national accounts program
as part of its effort to expand its customer base and to improve cross-selling
of its services. Premiere also plans to continue to enter into strategic
alliances and wholesale and licensing relationships in order to reach
additional customers that Premiere believes are likely to be extensive users
of its services.
 
  Pursue Strategic Acquisitions. Historically, Premiere has engaged in
acquisitions in order to obtain new technology, build its infrastructure and
increase its sales force and customer base. Premiere intends to continue to
examine acquisition and joint venture opportunities, which may accelerate its
growth, add new customers, develop new technologies or penetrate new
geographic markets.
   
  Expand International Presence. Premiere intends to deliver its services to
more international users through strategic partnerships, third-party
distribution agreements, direct sales efforts and relationships with existing
customers that have international operations. To accommodate these prospective
users, Premiere has opened a data and switching center in London and has also
begun development of a similar center in Toronto. Targeting the Pacific Rim,
Premiere expects to begin installation of a data and switching center in New
Zealand during 1998. These international centers are designed to reduce
transmission costs associated with system access from international locations
and to allow Premiere to more effectively pursue opportunities with
international customers and strategic partners. Additionally, Premiere expects
to increase the international scope of its private frame relay network by
installing POPs in additional overseas locations, specifically targeting the
United Kingdom for local messaging in the near future. See "Risk Factors--
Ability to Manage Growth; Acquisition Risks."     
 
VOICE-TEL ACQUISITIONS
   
  On June 12, 1997, Premiere announced the completion of the Voice-Tel
Acquisitions. The Voice-Tel Entities provide interactive digital voice
messaging products on a service bureau basis through approximately 210 POPs in
the United States, Puerto Rico, Canada, Australia and New Zealand. In
connection with the Voice-Tel Acquisitions, Premiere acquired various
components of, and now operates, VoiceTel's digital private frame relay
network and POPs.     
   
  Premiere believes that the Voice-Tel Acquisitions will broaden Premiere's
customer base by allowing Premiere to offer local access to certain of its
enhanced personal communications services customers. While Premiere's measured
800 access products have appealed primarily to a mobile customer base,
Premiere believes that a local access product will appeal to a broader base of
customers. In addition to the anticipated advantages of interconnected local
access, the Voice-Tel Acquisitions provide Premiere with a direct sales force
of approximately 300 persons in four countries, an expanded subscriber base
and the potential for greater cross-selling opportunities. Premiere is
currently consolidating these separate businesses by eliminating duplicative
and unnecessary costs, consolidating them under common management and
integrating Voice-Tel's service offerings, operations and systems with those
of Premiere. In connection with the Voice-Tel Acquisitions, Premiere took a
pre-tax charge in the second quarter of 1997 of approximately $45.4 million,
consisting of transaction expenses and restructuring and related costs
attributable to the Voice-Tel Acquisitions. See "Risk Factors--Ability to
Manage Growth; Acquisition Risks."     
 
VOICECOM ACQUISITION
   
  During the third quarter of 1997, Premiere acquired approximately 97.5% of
the outstanding capital stock of VoiceCom in exchange for approximately
446,000 shares of Premiere Common Stock. In addition, Premiere converted
existing VoiceCom options into options to acquire approximately 76,000 shares
of Premiere Common Stock. VoiceCom, based in Atlanta, Georgia, is a provider
of personal communications management services and telecommunication
outsourcing solutions to large corporations, government entities and mobile
professionals. Its service offerings include voice messaging, mobile
communications, full-service conference calling and voice response
programming. In connection with the acquisition of VoiceCom, Premiere took a
pre-tax charge in the third quarter of 1997 of approximately $28.2 million,
consisting of transaction expenses and

restructuring and related costs attributable to the acquisition of VoiceCom.
See "Risk Factors--Ability to Manage Growth; Acquisition Risks."     
   
  VCOM, which is an operating subsidiary of Premiere as a result of the
acquisition, has a customer base that includes several Fortune 500 companies,
including, among others, Abbott Laboratories ("Abbott Labs"), Beverly
Enterprises, Inc. ("Beverly Enterprises") and ConAgra, Inc. ("ConAgra").
Premiere plans to cross-sell its product offerings to VCOM's customer base.
    
ADDITIONS AND CHANGES TO MANAGEMENT
   
  To support its continuing growth, Premiere has recently added new management
personnel. These additions have included Jeffrey A. Allred, Executive Vice
President of Strategic Development; Curtis L. Garner, Jr., President of PCI;
William E. Welsh, President of VTE; and Randolph W. Salisbury, Senior Vice
President of Marketing of PCI. In addition, D. Gregory Smith, a co-founder of
Premiere, recently resigned as director, Executive Vice President and
Assistant Secretary of Premiere and as a director and officer of PCI and
certain other subsidiaries of Premiere, and Leonard A. DeNittis recently
resigned as the Vice President of Engineering and Operations of PCI. See "Risk
Factors--Additions and Changes to Management."

    or exercisable within 60 days of December 31, 1997 are deemed to be

                 CERTAIN DIFFERENCES IN THE RIGHTS OF PREMIERE
                           AND XPEDITE STOCKHOLDERS
 
  At the Effective Time, holders of Xpedite Common Stock will become holders
of Premiere Common Stock, and the rights as stockholders will be determined by
Premiere's Articles and Bylaws. In addition, Xpedite is a Delaware corporation
governed by the Delaware GCL and Premiere is a Georgia corporation governed by
the Georgia BCC. The following is a summary of the material differences in the
rights of stockholders of Xpedite and Premiere. Except as set forth below,
there are no material differences between the rights of an Xpedite stockholder
under Xpedite's Certificate and Bylaws and the Delaware GCL, on the one hand,
and the rights of a Premiere stockholder under Premiere's Articles and Bylaws
and the Georgia BCC, on the other hand. This summary does not purport to be a
complete discussion of, and is qualified in its entirety by reference to, the
Delaware GCL, the Georgia BCC and Certificate, Articles and Bylaws of each
corporation. See "Available Information" and "Incorporation of Certain
Information by Reference."
 
AUTHORIZED CAPITAL STOCK
   
  Xpedite. Xpedite's Certificate authorizes the issuance of up to (i)
15,000,000 shares of Xpedite Common Stock, of which 9,083,473 shares were
issued and outstanding and 72,000 shares were in held in Xpedite's treasury as
of January 23, 1998; (ii) 1,000,000 shares of preferred stock, par value $.01
per share ("Xpedite Preferred Stock"), of which none were outstanding or held
in Xpedite's treasury as of January 23, 1998, and of which 20,000 shares are
designated as the 8% Redeemable Preferred Stock. Xpedite's Certificate
authorizes the Xpedite Board of Directors, with the exception of the 8%
Redeemable Preferred Stock, to issue from time to time the Xpedite Preferred
Stock in one more series, to establish the number of shares to be included in
such series, and to fix the designation, powers, preferences and rights,
dividend rights, dividend rate, conversion rights, exchange rights, voting
rights, rights and terms of redemption (including sinking fund provisions),
the redemption price or prices, and the liquidation preferences of any wholly
unissued series of shares of Xpedite Preferred Stock, and to increase or
decrease the number of shares of any series subsequent to the issue of the
shares of that series, but not above the total number of authorized shares of
Xpedite Preferred Stock and not below the number of shares of such series then
outstanding, without any further action by the stockholders unless such action
is required by law or Xpedite's Certificate.     
   
  Premiere. Premiere's Articles authorize the issuance of up to (i)
150,000,000 shares of Premiere Common Stock, of which 33,966,198 shares (which
does not include the 329,840 outstanding Exchangeable Shares) were issued and
outstanding as of January 23, 1998; and (ii) 5,000,000 shares of preferred
stock, par value $.01 per share, of which one share, which has been designated
"Series B Voting Preferred Stock," par value $.01 per share, was outstanding
as of January 23, 1998. Premiere's Articles authorize the Premiere Board of
Directors, from time to time, to establish and designate part or all of the
preferred stock in such series and with such preferences, limitations and
relative rights as they may determine.     
 
DIRECTORS; VACANCIES
 
  Xpedite. Xpedite's Bylaws and Certificate provide for a Board of Directors
of not less than three nor more than nine directors, except that when all of
the capital stock is owned by less than three stockholders, the number of
directors may be less than three, but not less than the number of
stockholders. The Xpedite Board has the sole authority to determine the number
of directors and may increase or decrease the number of directors from time to
time, but a decrease in the number of directors may not have the effect of
shortening the term of any incumbent director. The number of directors has
been fixed at five. The Xpedite Board is classified in accordance with its
Certificate into three classes, as nearly equal in number as possible, with
each class elected to a three-year term, and the term of office of one class
expiring each year. Xpedite's Bylaws and Certificate provide that vacancies
may be filled by a majority of the directors then in office, though less than
a quorum, or by a sole remaining director. Xpedite's Bylaws provide that if
there are no directors then in office, an election of directors may be held in
the manner provided by statute. In addition, if, at the time of filling any
vacancy, the directors then in office constitute less than a majority of the
whole board, the Court of Chancery may, upon application of any
 
                                      102
<PAGE>
 
stockholder holding at least ten percent of the total number of shares
outstanding having the right to vote for such directors, summarily order an
election to be held to fill the vacancy, or to replace the directors chosen by
the directors then in office.
 
  Premiere. Premiere's Bylaws provide for a Board of Directors having such
number of members as shall be fixed by resolution of the Premiere Board of
Directors from time to time and, until otherwise determined, will be between
three and seven, provided that a decrease in the number of directors will not
have the effect of shortening the term of an incumbent director. The number of
directors was initially fixed by Premiere's Bylaws and Articles at five. The
Premiere Board is divided into three classes of directors, with each class
accounting for one-third, as near as may be, of the total, and each serving
for staggered three year terms. A vacancy occurring in the Premiere Board of
Directors may be filled for the unexpired term by the affirmative vote of a
majority of the remaining directors though less than a quorum (unless the
stockholders have elected a successor). If the vacant office, however, was
held by a director elected by a particular voting group, only the holders of
shares of that voting group or the remaining directors elected by that voting
group will be entitled to fill the vacancy, provided that if there is no
remaining director elected by that voting group, the other remaining directors
may fill the vacancy during the interim period before the stockholders of the
vacated director's voting group act to fill the vacancy.
 
REMOVAL OF DIRECTORS
 
  Xpedite. Xpedite's Certificate and Bylaws provide that a director may be
removed only for cause, and only by the holders of a majority of the
outstanding shares of all classes of capital stock of the corporation entitled
to vote in the election of directors, considered for this purposes as one
class. The Delaware GCL does not permit directors to remove other directors.
 
  Premiere. Premiere's Bylaws provide that any director, or the entire
Premiere Board of Directors, may be removed only for cause and only by holders
of 75% of the votes entitled to be cast, provided that directors elected by a
particular voting group may be removed only by the stockholders in that voting
group. Directors may not be removed without cause. The Georgia BCC permits the
articles of incorporation or a bylaw adopted by the stockholders to govern the
removal of directors.
 
VOTING RIGHTS
 
  Xpedite. Unless otherwise provided in Xpedite's Certificate, each
stockholder is entitled to one vote for each share of Xpedite's capital stock
having voting power held by such stockholder.
 
  Premiere. Premiere's Bylaws provide that, unless otherwise required by the
Georgia BCC or Premiere's Articles, each outstanding share of any class or
series having voting rights is entitled to one vote on each matter that is
submitted to a vote of stockholders. Premiere's Articles give the holder of
the Premiere Preferred Stock a number of votes equal to the number of votes
that the holders of Exchangeable Shares (referred to above) would be entitled
if all such Exchangeable Shares were exchanged for shares of Premiere Common
Stock. In respect of all matters concerning the voting of shares, the Premiere
Preferred Stock and Premiere Common Stock vote as a single class.
 
STOCKHOLDER MEETINGS
 
  Xpedite. The Delaware GCL provides that special meetings of stockholders may
be called only by the directors or any other person as may be authorized by
the corporation's certificate of incorporation or bylaws. Xpedite's Bylaws
provide that special meetings of the stockholders may be called for any
purpose, unless otherwise prescribed by statute or the Certificate, either by
the Chairman of the Board or the President and shall be called by the
Secretary, upon written request, or by resolution adopted by the affirmative
vote of a majority of the Xpedite Board of Directors. Stockholders are not
entitled to request a special meeting. Written notice of a special meeting,
stating the place, date and hour of the meeting and the purpose for which the
meeting is called,
 
                                      103
<PAGE>
 
must be given not less than ten nor more than sixty days before the date of
such meeting, to each stockholder entitled to vote at such meeting.
 
  Premiere. The Georgia BCC permits the board of directors or any person
specified in the corporation's articles of incorporation or bylaws to call
special meetings of stockholders. A special meeting may also be called by the
holders of at least 25%, or such greater or lesser percentages as the articles
of incorporation or bylaws provide, of all votes entitled to be cast on any
issue proposed to be considered at a special meeting. Premiere's Bylaws
provide that special meetings of the stockholders or a class or series of
stockholders may be called at any time by the Premiere Board of Directors, the
Chairman of the Board or the President of Premiere, and that such meetings
shall be called upon the written request of the holders of shares representing
at least 75% of the votes entitled to be cast on each issue presented at such
meeting (25% at any time Premiere has fewer than 100 shareholders of record).
Premiere must give written notice of the date, time, and place of special
stockholders' meeting no fewer than ten days nor more than 60 days before the
meeting date to each stockholder of record entitled to vote at the meeting.
Such notice must state the purpose for which the meeting is called.
 
AMENDMENT OF CERTIFICATE OR ARTICLES AND BYLAWS
 
  Xpedite. The Delaware GCL permits a corporation to amend its certificate of
incorporation so long as the amended certificate of incorporation contains
only provisions it would be lawful and proper to insert in an original
certificate of incorporation filed at the time the amendment is filed. Without
limiting the general power of amendment, the Delaware GCL specifically allows
a corporation to amend its certificate of incorporation so as to (i) change
its corporate name, (ii) change the nature of its business or its corporate
powers and purposes, (iii) increase, decrease or reclassify its authorized
capital stock, (iv) cancel or otherwise affect the right of the holders of
shares of any class to receive accrued, undeclared dividends, (v) create a new
class of stock, or (vi) change the duration of the corporate charter. All
amendments must be approved by the Xpedite Board of Directors and the
stockholders by the affirmative vote of a majority of outstanding stock
entitled to vote thereon, and a majority of the outstanding stock of each
class entitled to vote thereon as a class. Xpedite's Certificate states that
the corporation reserves the right to amend, alter, change or repeal any
provision contained in Xpedite's Certificate.
 
  Under the Delaware GCL, the power to adopt, amend, or repeal bylaws rests
with those stockholders entitled to vote, provided that any corporation's
certificate of incorporation may additionally confer such power upon the
directors. Conferring the power to adopt, amend or repeal bylaws upon the
directors may not divest, nor limit, the stockholders' power to adopt, amend
or repeal bylaws. Xpedite's Certificate authorizes the Xpedite Board to make,
alter or repeal Xpedite's Bylaws. Xpedite's Bylaws provide that the Bylaws may
be altered, amended, or repealed or new Bylaws adopted by the stockholders or
by the Xpedite Board. The power to adopt, amend or repeal the Xpedite Bylaws
conferred upon the Xpedite Board by Xpedite's Certificate does not divest or
limit the power of the stockholders to adopt, amend, or repeal the Xpedite
Bylaws.
 
  Premiere. Under the Georgia BCC, the Premiere Board of Directors may adopt
certain amendments to the articles of incorporation including, among others,
amendments to (i) delete the names and address of the initial directors,
initial registered agent or registered office, (ii) change each issued and
unissued authorized share of an outstanding class of stock into a greater
number of whole shares if the corporation has only shares of that class
outstanding, (iii) make certain minor changes to the corporate name, (iv)
extend the corporation's duration if it was incorporated at a time the law
required limited duration, or (v) change or eliminate the par value of each
issued and unissued share of an outstanding class if the corporation has only
shares of that class outstanding. Other amendments must be approved by the
board of directors and by the shareholders by a majority of the votes entitled
to be cast on the amendment by each voting group entitled to vote on the
amendment, with each class voting separately. Premiere's Articles do not
contain a provision which alters the Georgia BCC requirements with respect to
amending a corporation's articles.
 
  The Georgia BCC permits a corporation's Board of Directors to amend, repeal
or adopt bylaws, unless (i) the articles of incorporation reserve this power
exclusively to stockholders, or (ii) the stockholders expressly
 
                                      104
<PAGE>
 
reserve the power to amend or repeal a particular bylaw. The stockholders
alone may amend, repeal or adopt bylaws limiting the authority of the board of
directors or establishing staggered terms for directors. In addition, the
Board of Directors may not amend, repeal, or adopt a bylaw fixing a greater
stockholder quorum or voting requirement. Premiere's Bylaws state that, except
as provided under the Georgia BCC, the Premiere Board of Directors has the
power to alter, amend, or repeal the Bylaws or adopt new Bylaws. Any Bylaws
adopted by the Premiere Board of Directors may be altered, amended, or
repealed, and new Bylaws adopted, by the stockholders, upon the affirmative
vote of the holders of 75% of the shares entitled to vote on the matter.
Premiere's Bylaws also provide that the stockholders may prescribe in adopting
any Premiere Bylaw that such Premiere Bylaw not be altered, amended, or
repealed by the Premiere Board of Directors.
 
INDEMNIFICATION AND DIRECTOR EXCULPATION
 
  Xpedite. The Delaware GCL allows a corporation to indemnify their directors
and officers against civil and criminal liabilities incurred if the directors
and officers acted in good faith and in a manner the directors and officers
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action, if they had no
reasonable cause to believe their conduct was unlawful.
 
  Xpedite's Bylaws provide that Xpedite will, to the broadest and maximum
extent permitted by the Delaware GCL, as it exists from time to time (except
in the case of an amendment to the Delaware GCL, only to the extent that such
amendment permits Xpedite to provide broader rights of indemnification),
indemnify each person who is or was a party, or threatened to become a party,
in any civil, criminal, administrative proceeding or investigation by reason
of the fact that the person is or was a director or officer of Xpedite, or
serving at the request of Xpedite as a director, officer, employee, or agent
of another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by such person in
connection with such proceeding, and pay to such person such expenses in
advance of the final disposition of the proceeding upon receipt of an
undertaking to repay such amount if it be determined that such person is not
entitled to indemnification. Xpedite, however, will not indemnify a person
with respect to the following: (i) remuneration paid to such person if it
shall be determined that such remuneration was in violation of law; or (ii)
any accounting of profits made for the purchase or sale by such person of the
corporation's securities within the meaning of Section 16(b) of the Exchange
Act or similar provisions of any federal, state or local statutory law; or
(iii) actions brought about or contributed by the dishonesty of such person,
if such acts were committed with actual dishonest purpose and were material to
the adjudication; or (iv) actions based on or attributable to such person
having gained any personal profit or advantage to which such person was not
entitled; or (v) any matter in respect of which a final decision by a court
with competent jurisdiction determines that indemnification is unlawful.
 
  Xpedite's Certificate limits or eliminates, to the fullest extent that the
Delaware GCL permits, the personal liability of a director to Xpedite or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided that the liability of a director may not be eliminated or limited (i)
for any breach of the director's duty of loyalty to Xpedite or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) for violations
under Section 174 of the Delaware GCL (which makes directors liable for
unlawful distributions), or (iv) for any transaction from which the director
derived an improper personal benefit.
 
  Premiere. Under the Georgia BCC, a corporation may indemnify any director or
officer made a party to a proceeding if such director or officer acted in a
manner he or she believed in good faith to be in or not opposed to the best
interests of the corporation and, in the case of any criminal proceeding, had
no reasonable cause to believe his conduct was unlawful. A corporation may not
indemnify a director in a derivative proceeding, or in a proceeding by or in
the right of the corporation, in which the director is adjudged liable to the
corporation, or in connection with any other proceeding in which he is
adjudged liable on the basis he improperly received a personal benefit. The
corporation may not indemnify a director unless a determination is made that
he or she has met the applicable standard of conduct. The corporation is
required to indemnify a director to the extent that the director has been
successful in the defense of a proceeding.
 
                                      105
<PAGE>
 
  Premiere's Articles eliminate a director's personal liability to Premiere or
any of its stockholders for any breach of duties of such position, to the
fullest extent permitted by the Georgia BCC. Accordingly, such elimination of
liability does not apply to (i) appropriations of business opportunities from
the company, (ii) knowing or intentional misconduct or violation of law, (iii)
liability for assent to distribution which are illegal or improper under the
Georgia BCC or Premiere's Articles, and (iv) liability for any transaction in
which an improper personal benefit is derived. In addition, Premiere's
Articles state that if the Georgia BCC is ever amended to allow for greater
exculpation of directors than presently permitted, the directors shall be
relieved from liabilities to the fullest extent provided by the Georgia BCC,
as so amended, without further action by the Premiere Board or the
stockholders, unless the Georgia BCC provides otherwise. No modification or
repeal of this provision will adversely affect the elimination or reduction in
liability provided thereby with respect to any alleged act occurring before
the effective date of such modification or repeal.
 
  Premiere's Board of Directors has the power to cause the corporation to
provide to officers, employees, and agents of Premiere ("Indemnified Persons")
all or part of the right to indemnification permitted for such persons under
the Georgia BCC. Premiere shall also provide to each director, and the
Premiere Board of Directors have the power to cause the corporation to provide
to any officer, employee, or agent of Premiere who is or was serving at
Premiere's request as a director, officer, partner, trustee, employee, or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan, or other enterprise ("Indemnified Persons") all or part of the
right to indemnification and similar rights permitted for such persons under
the Georgia BCC.
 
  Premiere's Bylaws allow the Premiere Board of Directors to specify that
advancement of expenses may be made available to a director or Indemnified
Person, provided that the director or Indemnified Person give Premiere a
written affirmation of his or her good faith belief that he or she has met the
applicable standard of conduct and a written agreement to repay to Premiere
any such advances if it is later determined that the director or Indemnified
Person is not entitled to be indemnified by Premiere for such amounts.
 
  Premiere's Bylaws provide that these rights of indemnification and
advancement of expenses, unless otherwise provided when such right are
granted, will continue as to a person who has ceased to be director, officer,
employee, or agent and will inure to the benefit of the heirs, executors, and
administrators of such person.
 
ACTIONS BY STOCKHOLDERS WITHOUT A MEETING
 
  Xpedite. Unless a corporation's certificate of incorporation otherwise
provides, the Delaware GCL permits any action required to be taken at an
annual or special meeting of stockholders to be taken without a meeting,
without prior notice and without a vote, if a written consent setting forth
the action taken is signed by the holders of outstanding stock having not less
than the minimum number of votes necessary to authorize or take such action at
a meeting where all shares entitled to vote thereon were present and voted,
and shall be delivered to the corporation in accordance with the Delaware GCL.
Xpedite's Certificate provides that its stockholders do not have the power to
act by means of written consent.
 
  Premiere. Under the Georgia BCC, any action required or permitted to be
taken by vote may be taken without a meeting by written consent, setting forth
the action so taken and signed by holders of all of the shares entitled to
vote on the action, provided that the articles of incorporation may permit
action by written consent of the holders of less than all outstanding shares.
Premiere's Bylaws provide that actions required to be taken at a stockholder
meeting may be taken without a meeting only if the unanimous written consent
of the stockholders entitled to vote at such meeting is obtained and delivered
to Premiere for inclusion in its minute book or other corporate records.
 
PAYMENT OF DIVIDENDS
 
  Xpedite. The Delaware GCL provides that, subject to any restrictions in a
corporation's certificate of incorporation, dividends may be declared from a
corporation's surplus or, if there is no surplus, from its net profits for the
fiscal year in which the dividend is declared and the preceding fiscal year.
However, if the
 
                                      106
<PAGE>
 
corporation's capital (generally defined in the Delaware GCL as the sum of the
aggregate par value of all shares of the corporation's capital stock, where
all such shares have a par value and the board of directors has not
established a higher level of capital) has been diminished to an amount less
than the aggregate amount of the capital represented by the issued and
outstanding stock of all classes having a preference upon the distribution of
assets, dividends may not be declared and paid out of such net profits until
the deficiency in such capital has been repaired.
 
  Xpedite's Bylaws provide that dividends upon its capital stock, subject to
the provisions of Xpedite's Certificate, may be declared by the Xpedite Board
at any regular or special meeting. Dividends may be paid in cash, in property,
or in shares of the capital stock, subject to provisions of Xpedite's
Certificate. Before the payment of a dividend, the Xpedite Board may set aside
such sums as they, from time to time, in their absolute discretion, think
proper as reserves to meet contingencies, for equalizing dividends, for
repairing or maintaining any property of the corporation, or for such other
purpose as the directors shall think conducive to the interest of the
corporation, and the directors may modify or abolish such reserve in the
manner in which it was created.
 
  Premiere. The Georgia BCC provides that a board of directors may authorize
and a corporation may make distributions to its stockholders subject to any
restrictions imposed in the corporation's articles of incorporation, except
that no distribution may be made if, after giving it effect: (i) the
corporation would not be able to pay its debts as they become due in the usual
course of business, or (ii) the corporation's total assets would be less than
the sum of its total liabilities plus (unless the articles of incorporation
permit otherwise) the amount that would be needed, if the corporation were to
be dissolved at the time of the distribution, to satisfy the preferential
rights upon dissolution of stockholders whose preferential rights are superior
to those receiving the distribution. Unless Premiere's Articles provide
otherwise, pursuant to Premiere's Bylaws, the Premiere Board of Directors,
from time to time in its discretion, may authorize or declare distributions or
share dividends in accordance with the Georgia BCC. Premiere's Articles
provide that the holder of Premiere Preferred Stock is not entitled to receive
any dividends declared and paid by Premiere.
 
DISSOLUTION AND LIQUIDATION
 
  Xpedite. The Delaware GCL requires the approval of the Xpedite Board and the
holders of a majority of the outstanding stock of a corporation entitled to
vote thereon for voluntary dissolution of a Delaware corporation. Xpedite's
Certificate and Bylaws do not contain a provision which alters the Delaware
GCL requirements with respect to dissolutions.
 
  Premiere. The Georgia BCC requires approval of the Premiere Board of
Directors (unless the Board elects because of a conflict of interest or other
special circumstances to make no recommendation) and the holders of a majority
of all the votes entitled to be cast (unless the articles of incorporation
require a greater vote or voting by groups) for voluntary dissolution of a
Georgia corporation. Premiere's Articles and Bylaws do not contain a provision
which alters the Georgia BCC requirements with respect to dissolutions. In the
event of liquidation, dissolution, or winding up of Premiere, and subject to
any prior rights of holders of preferred stock ranking senior to the Premiere
Preferred Stock, the holder of the share of Premiere Preferred Stock will be
paid in an amount equal to $1.00, together with payment to any class of stock
ranking equally with Premiere Preferred Stock.
 
MERGER, CONSOLIDATION, AND SALE OF ASSETS
 
  Xpedite. The Delaware GCL requires the approval of the Xpedite Board and the
holders of a majority of the outstanding stock of a corporation entitled to
vote thereon for mergers or consolidations involving a Delaware corporation,
and for sales, leases, or exchanges of substantially all of a Delaware
corporation's property and assets. The Delaware GCL does not provide
explicitly for share exchanges. The Delaware GCL permits Xpedite to merge with
another corporation without obtaining the approval of its stockholders if:
(i) Xpedite is the surviving corporation of the merger; (ii) the merger
agreement does not require an amendment to Xpedite's Certificate; (iii) each
share of Xpedite stock outstanding immediately prior to the effective date of
the merger is to be an identical outstanding or treasury share of Xpedite
after the merger; and (iv) any authorized but unissued
 
                                      107
<PAGE>
 
shares or treasury shares of Xpedite Common Stock to be issued or delivered
under the plan of merger plus those initially issuable upon conversion of any
other securities or obligations to be issued or delivered under such plan do
not exceed 20% of the shares of Xpedite Common Stock outstanding immediately
prior to the effective date of the merger. The Xpedite Certificate and Bylaws
do not contain a provision which alters the Delaware GCL voting requirements
with respect to mergers.
 
  Premiere. The Georgia BCC generally requires the affirmative vote of a
majority of all votes entitled to be cast on the matter, voting as a single
group, to approve mergers and share exchanges. Stockholders of the surviving
corporation need not approve a merger if (i) the articles of incorporation of
the surviving corporation will not differ from its articles before the merger;
(ii) each stockholder of the surviving corporation whose shares were
outstanding immediately before the effective date of the merger will hold the
same number and type of shares immediately after the merger; (iii) the number
and kind of shares outstanding immediately after the merger, plus the number
and kind of shares issuable as a result of the merger, do not exceed the total
number and kind of shares of the surviving corporation authorized by its
articles of incorporation immediately before the merger. Premiere's Articles
and Bylaws do not contain a provision which alters the Georgia BCC voting
requirements with respect to mergers.
 
BUSINESS COMBINATIONS WITH CERTAIN PERSONS
 
  Xpedite. Section 203 of the Delaware GCL, "Business Combinations with
Interested Shareholders," prohibits a corporation that does not opt out of its
provisions from entering into certain business combination transactions with
"interested stockholders" (generally defined to include persons beneficially
owning 15% or more of the corporation's outstanding capital stock) unless
certain super majority votes are obtained. Xpedite has not opted out of
Section 203 in its Certificate and consequently is subject to the restrictions
contained in Section 203.
 
  Premiere. Pursuant to its Bylaws, Premiere is subject to the provisions of
the Georgia BCC, including provisions prohibiting various "business
combinations" involving "interested shareholders" for a period of five years
after the shareholder becomes an interested shareholder of Premiere. Such
provisions prohibit any business combination with an interested shareholder
unless either (i) prior to such time, the Premiere Board of Directors approves
either the business combination or the transaction by which such stockholder
became an interested shareholder, (ii) in the transaction that resulted in the
stockholder becoming an interested shareholder, the interested shareholder
became the beneficial owner of at least 90% of the outstanding voting stock of
Premiere which was not held by directors, officers, affiliates thereof,
subsidiaries or certain employee stock option plans of Premiere, or (iii)
subsequent to becoming an interested shareholder, such stockholder acquired
additional shares resulting in such stockholder owning at least 90% of the
outstanding voting stock of Premiere and the business combination is approved
by a majority of the disinterested stockholders' shares not held by directors,
officers, affiliates thereof, subsidiaries or certain employee stock option
plans of Premiere. Under the relevant provisions of the Georgia BCC, a
"business combination" is defined to include, among other things, (i) any
merger, consolidation, share exchange or any sale, transfer or other
disposition (or series of related sales or transfers) of assets of Premiere
having an aggregate book value of 10% or more of Premiere's net assets
(measured as of the end of the most recent fiscal quarter), with an interested
shareholder of Premiere or any other corporation which is or, after giving
effect to such business combination, becomes an affiliate of any such
interested shareholder, (ii) the liquidation or dissolution of Premiere, (iii)
the receipt by an interested shareholder of any benefit from any loan,
advance, guarantee, pledge, tax credit or other financial benefit from the
Premiere, other than in the ordinary course of business and (iv) certain other
transactions involving the issuance or reclassification of securities of
Premiere which produce the result that 5% or more of the total equity shares
of Premiere, or of any class or series thereof, is owned by an interested
shareholder. An "interested shareholder" is defined by the Georgia BCC to
include any person or entity that, together with its affiliates, beneficially
owns or has the right to own 10% or more of the outstanding voting shares of
Premiere, or any person that is an affiliate of Premiere and has, at any time
within the preceding two-year period, been the beneficial owner of 10% or more
of the outstanding voting shares of Premiere. The restrictions on business
combinations shall not apply to any person who was an interested shareholder
before the adoption of the Bylaw which made the provisions
 
                                      108
<PAGE>
 
applicable to Premiere nor to any persons who subsequently become interested
shareholders inadvertently, subsequently divest sufficient shares so that the
shareholder ceases to be an interested shareholder and would not, at any time
within the five-year period immediately before a business combination
involving the shareholder have been an interested shareholder but for the
inadvertent acquisition.
 
  The Georgia BCC also contains a provision concerning "Fair Price
Requirements" (the "Fair Price Provision") which imposes certain requirements
on "business combinations" of a Georgia corporation with any person who is an
"interested shareholder" of that corporation. Under the Fair Price Provision,
business combinations with interested shareholders must meet one of three
criteria designed to protect the minority shareholders: (i) the transaction
must be unanimously approved by the "continuing directors" of the corporation
(generally directors who served prior to the time the interested shareholder
acquired 10% ownership and who are unaffiliated with the interested
shareholder); or (ii) the transaction must be approved by two-thirds of the
continuing directors and a majority of shares held by stockholders other than
the interested shareholder; or (iii) the terms of the transaction must meet
specified fair pricing criteria and certain other tests. A Georgia
corporation's bylaws must specify that all requirements of the Fair Price
Provision apply to the corporation in order for the Fair Price Provision to
apply. The Premiere Bylaws, however, do not presently contain a provision
electing to be governed by the Fair Price Provision.
 
DISSENTERS' RIGHTS OF APPRAISAL
 
  Xpedite. Pursuant to the Delaware GCL, any stockholder has the right to
dissent from any merger or consolidation, except as described below, of which
Xpedite is a constituent corporation. No such appraisal rights are available
for the shares of any class or series of Xpedite capital stock if (i) as of
the record date fixed to determine the stockholders entitled to receive notice
of and to vote at the meeting of stockholders to act upon the agreement of
merger or consolidation, such shares were either listed on a national
securities exchange, designated as a national market system security on an
automated quotations system operated by a national securities association, or
held of record by more than 2,000 stockholders, or (ii) Xpedite is the
surviving corporation of a merger and the merger did not require the approval
of Xpedite's stockholders, unless in either case, the holders of such stock
are required by an agreement of merger or consolidation to accept for that
stock something other than: (a) shares of stock of the corporation surviving
or resulting from the merger or consolidation; (b) shares of stock of any
other corporation that, at the effective date of the merger, will be listed on
a national securities exchange or held of record by more than 2,000
stockholders; (c) cash in lieu of fractional shares of a corporation described
in clause (a) or (b) above; or (d) any combination of the shares of stock and
cash in lieu of fractional shares described in clauses (a) through (c) above.
Stockholders who perfect their appraisal rights are entitled to receive cash
from the corporation equal to the value of their shares as established by
judicial appraisal. Corporations may enlarge these statutory rights by
including in their certificate of incorporation a provision allowing appraisal
rights in any merger in which the corporation is a constituent corporation.
Xpedite's Certificate contains no provision enlarging such appraisal rights.
 
  Premiere. The Georgia BCC grants stockholders the right to dissent and
receive payment of the fair value of their shares in the event of certain
amendments or changes to the articles of incorporation adversely affecting
their shares, or certain business transactions, including certain mergers.
This right is not available when the affected shares are listed on a national
securities exchange (which is defined in the Georgia BCC to include Nasdaq) or
held of record by more than 2,000 stockholders unless (i) the articles of
incorporation or a resolution of the board of directors approving the
transaction provide otherwise, or (ii) in a plan of merger or share exchange,
the holders of such shares are required to accept anything other than shares
of the surviving corporation or another publicly held corporation, except for
payments in lieu of fractional shares. Premiere's Articles do not modify this
limitation on dissenters' appraisal rights.
 
STOCKHOLDER'S RIGHT TO EXAMINE BOOKS AND RECORDS
 
  Xpedite. The Delaware GCL provides that a stockholder may inspect books and
records upon written demand under oath stating the purpose of the inspection,
if such purpose is reasonably related to such person's interest as a
stockholder.
 
                                      109
<PAGE>
 
  Premiere. The Georgia BCC states that stockholders are entitled to inspect
and copy the following records of the corporation upon at least five days
prior written notice: (i) its articles and any amendments thereto; (ii) its
bylaws and any amendments thereto; (iii) resolutions adopted by either its
stockholders or board of directors increasing or decreasing the number of
directors, the classification of directors, if any, and the names and
residence addresses of all members of the board of directors; (iv) resolutions
adopted by its board of directors creating one or more classes or series of
shares, and fixing their relative rights preferences, and limitations, if
shares issued pursuant to those regulations are outstanding and any
resolutions adopted by the board of directors that affect the size of the
board of directors; (v) the minutes of all stockholders' meetings, executed
waivers of notice of meetings, and executed written consents evidencing all
action taken by stockholders without a meeting, for the past three years; (vi)
all written communications to stockholders generally within the past three
years, including the financial statements furnished for the past three years
under Section 14-2-1620 of the Georgia BCC; (vii) a list of the names and
business addresses of its current directors and officers; and (viii) its most
recent annual registration delivered to the Secretary of State under Section
14-2-1622 of the Georgia BCC.
 
  Shareholders are entitled to inspect and copy, upon at least five days prior
notice, (i) excerpts from minutes of any meeting of the board of directors or
stockholders, or records of any action taken by a committee of the board
acting on behalf of the corporation, the shareholders, or the board of
directors taken without a meeting, (ii) accounting records of the corporation,
and (iii) the record of stockholders, if (w) such demand is made in good faith
and for a proper purpose that is reasonably relevant to his or her legitimate
interest as a stockholder, (x) the shareholder describes with reasonable
particularity his or her purpose and the records he or she desires to inspect,
(y) the records are directly connected to such purpose, and (z) the records
are to be used only for the stated purpose. The right to inspect these
documents may also be limited by a corporation's articles of incorporation or
bylaws for stockholders owning two percent or fewer of the shares outstanding.
 
  Pursuant to Premiere's Bylaws, the Board of Directors has the power to
determine which accounts, books, and records of the corporation will be
available for stockholders to inspect or copy, except for those books and
records required by the Georgia BCC to be made available upon compliance by a
stockholder with applicable requirements. The Premiere Board of Directors are
also granted the power to fix reasonable rules and regulations (including
confidentiality restrictions and procedures), not in conflict with applicable
law, for the inspection and copying of accounts, books, and records that by
law or by determination of the Premiere Board of Directors are made available.
Unless required by the Georgia BCC or otherwise provided by the Premiere Board
of Directors, a shareholder holding less than two percent of the total shares
of Premiere then outstanding has no right to inspect Premiere's books and
records.
 
CONSIDERATION OF SOCIETAL FACTORS
 
  Xpedite. Delaware does not explicitly provide for the consideration of
societal interests by a corporation's board of directors in making decisions.
The Delaware Supreme Court has, however, held that, in discharging their
responsibilities to a corporation, directors may consider constituencies other
than stockholders, such as creditors, customers, employees and perhaps even
the community in general, as long as there are rationally related benefits
accruing to stockholders as well. The Delaware Supreme Court has held,
however, that concern for non-stockholder interest is inappropriate when a
sale of a company is inevitable and an auction among active bidders is in
progress. Xpedite's Certificate does not directly discuss consideration of
societal factors.
 
  Premiere. In addition to considering the effects of any action on the
company and its stockholders, Premiere's Articles permit the Premiere Board of
Directors and the committees and the individual members thereof to consider
the interests of various constituencies, including employees, customers,
suppliers, and creditors of Premiere, communities in which Premiere maintains
offices or operations, and other factors which such directors deem pertinent,
in carrying out and discharging the duties and responsibilities of such
positions and in determining what is believed to be in the best interests of
Premiere. This provision solely grants discretionary authority to the
directors and should not be deemed to provide to any other constituency any
right to be considered.

INTERESTED DIRECTOR TRANSACTIONS
 
  Xpedite. The Delaware GCL provides that no transaction between Xpedite and
one or more of its directors or officers or an entity in which one or more of
its directors or officers are directors or officers of have a financial
interest, shall be void or voidable solely for that reason. In addition, no
such transaction shall be void or voidable solely because the director or
officer is present at, participates in, or votes at the meeting of the board
of directors or committee which authorizes the transaction. In order that such
a transaction not be found void or voidable, it must, after disclosure of
material facts, be approved by disinterested directors, a committee of
disinterested directors, or stockholders, or the transaction must be fair as
to the corporation.
 
  Premiere. Pursuant to the Georgia BCC, if a director has a conflicting
interest respecting a transaction, such transaction needs to receive the
affirmative vote of a majority (but not less than two) of those qualified
directors on the board of directors who voted on the transaction after either
(i) disclosure by the director who has a conflicting interests of (a) the
existence and nature of his conflicting interests and (b) all facts known to
him respecting the subject matter that an ordinarily prudent person would
reasonably believe to be material to a judgment as to whether or not to
proceed with the transaction; or (ii) the interested director (a) prior to the
vote, discloses to the directors voting on the transaction the existence and
nature of the conflicting interest, and the character of and limitations
imposed by the interested director's duty under law or professional canon, or
duty of confidentiality, that causes the director to be unable to make the
disclosure described above and (b) plays not part, directly or indirectly, in
their deliberations or vote.
 
PREEMPTIVE RIGHTS
 
  Xpedite. The Delaware GCL does not automatically confer preemptive rights on
stockholders, therefore stockholders have no preemptive rights unless and
except to the extent the corporation's certificate of incorporation expressly
grants such rights. Xpedite's Certificate does not contain a provision
expressly granting preemptive rights, consequently holders of shares of
Xpedite's capital stock do not have preemptive rights.
 
  Premiere. Under the Georgia BCC, the stockholders of all corporations do not
have preemptive rights except to the extent the articles of incorporation so
provide. Premiere's Articles do not grant its stockholders preemptive rights.
 
STOCKHOLDER ACTION--QUORUM AND VOTING REQUIREMENTS
 
  Xpedite. The Delaware GCL allows a corporation's certificate of
incorporation or bylaws to specify the number of shares and/or the amount of
other securities having voting power whose holders shall be present or
represented by proxy at any meeting in order to constitute a quorum for, and
the votes that shall be necessary for, the transaction of any business, but
requires the quorum to consist of at least one-third of the shares entitled to
a vote at the meeting. Absent specifications in the certificate of
incorporation or bylaws of the corporation a majority of the shares entitled
to vote, present in person or represented by proxy, constitutes a quorum at a
stockholders' meeting and in all matters other than the election of directors,
the affirmative vote of a majority of shares present in person or represented
by proxy at the meeting and entitled to vote will be the action of the
stockholders. Directors are elected by a plurality of the votes of the shares
present in person or represented by proxy at the meeting and entitled to vote
on the election. Where a separate vote by class or classes is required, a
majority of the outstanding shares of such class or classes, present in person
or represented by proxy, constitutes a quorum entitled to take action with
respect to the vote on that matter, and the affirmative vote of the majority
of shares of class or classes present in person or represented by proxy at the
meeting and entitled to vote is the act of the class. Neither Xpedite's
Certificate or Bylaws modify the Delaware GCL's quorum or voting requirements
for shareholder action. Xpedite's Certificate does not authorize cumulative
voting.
 
  Premiere. According to the Georgia BCC, shares entitled to vote as a
separate group may take action on a matter at a meeting only if a quorum of
those shares exist with respect to that matter. Unless a corporation's
articles of incorporation or the Georgia BCC provides otherwise, a majority of
the votes entitled to be cast on the matter by the voting group constitutes a
quorum of that voting group of action on that matter. The Georgia
 
                                      111
<PAGE>
 
BCC further provides that if a quorum exists, action on a matter (other than
the election of directors) by a voting group is approved if the votes cast
within the voting group favoring the action exceed the votes cast opposing the
action unless the Georgia BCC, the articles of incorporation, or a provision
of the bylaws adopted by the shareholders in accordance with the Georgia BCC
or any successor statute, requires a greater number of affirmative votes.
According to the Georgia BCC, unless otherwise provided in the articles of
incorporation, directors are elected by a plurality of votes cast by the
shares entitled to vote in the election at a meeting at which a quorum is
present. The articles of incorporation or a bylaw adopted according to the
Georgia BCC may provide for a greater or lesser quorum (but not less than one-
third of the votes entitled to be cast) or a greater voting requirement for
shareholders (or voting groups of shareholders) than is provided for in the
Georgia BCC; however, an amendment to the articles of incorporation of bylaws
that changes or deletes a greater quorum or voting requirement must meet the
same quorum requirement and be adopted by the same vote and voting groups
required to take action under the quorum and voting requirements prescribed in
the provision being amended. Neither Premiere's Articles or Bylaws modify the
Georgia BCC's quorum or voting requirements for stockholder action. Premiere's
Articles do not authorize cumulative voting.
 
ANNUAL MEETING OF STOCKHOLDERS
 
  Xpedite. The Delaware GCL requires a corporation to hold an annual meeting
of stockholders to elect directors and transact any other proper business as
the bylaws designate. Xpedite's Certificate provides that, except as otherwise
required by law, meetings of the stockholders may be called only by the Board
of Directors pursuant to a resolution approved by a majority of directors, or
by the Chairman of the Xpedite Board or the President. Stockholders are not
permitted to call an annual meeting or to require that the Xpedite Board call
an annual meeting. Xpedite's Bylaws provide that annual meetings of
stockholders will be held on the second Tuesday in May if not a legal holiday,
and if a legal holiday, the on the next secular day following, at 10:00 a.m.,
or at such other date and time as shall be designated from time to time by the
Xpedite Board and stated in a notice of the meeting.
 
  Premiere. The Georgia BCC provides that a corporation shall hold a meeting
of stockholders at a time stated in or fixed in accordance with the bylaws.
Premiere's Bylaws state that the annual meeting of stockholders will be held
at a time determined by the Premiere Board of Directors.

Surviving Corporation, or as otherwise provided by law.
 
                                      A-1
<PAGE>
 
  SECTION 2.06. OFFICERS. The officers of the Company at the Effective Time

Surviving Corporation, or as otherwise provided by law.
 
  SECTION 2.07. EFFECTIVE TIME. The Merger shall become effective at the time
of filing of a certificate of merger reflecting the Merger (the "Certificate
of Merger") with the Secretary of State of the State of Delaware in accordance
with the provisions of Section 251 of the GCL. The Certificate of Merger shall
be filed with the Secretary of State of the State of Delaware on the Closing
Date. The time when the Merger becomes effective is herein referred to as the

                                 ARTICLE III.
 
               EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
              CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES
 
  SECTION 3.01. EFFECT ON COMPANY COMMON STOCK.
 
    (a) Except as otherwise provided herein, each share of common stock, par
  value $.01 per share of the Company (each, a "SHARE" or collectively, the
  "SHARES" or the "COMPANY COMMON STOCK") actually issued and outstanding
  immediately prior to the Effective Time (except for the Excluded Shares)
  shall, at the Effective Time, by virtue of the Merger and without any
  action on the part of the holder thereof, be converted into and
  exchangeable for that multiple of a share (rounded to the nearest one-
  thousandth of a share) of the common stock, par value $.01 per share, of
  Parent ("PARENT COMMON STOCK") obtained by dividing $34.00 by the Average
  Closing Price (as defined below) (as the same may be adjusted pursuant to
  this Agreement, the "EXCHANGE RATIO"). "AVERAGE CLOSING PRICE" shall mean
  the average of the daily last sale prices for the shares of Parent Common
  Stock for the twenty (20) consecutive trading days on which such shares are
  actually traded as over-the-counter securities and quoted on the Nasdaq
  National Market ("NASDAQ") (as reported by The Wall Street Journal or, if
  not reported thereby, any other authoritative source selected by Parent and
  the Company) ending at the close of trading on the trading day immediately
  preceding the date of the Company Stockholders Meeting (the "DETERMINATION
  DATE")); provided, that for purposes of this SECTION 3.01, the Average
  Closing Price shall be deemed to equal $27.20 (the "MINIMUM AVERAGE CLOSING
  PRICE") in the event the actual Average Closing Price is less than the
  Minimum Average Closing Price and shall be deemed to equal $39.20 (the
  "MAXIMUM AVERAGE CLOSING PRICE") in the event the actual Average Closing
  Price is greater than the Maximum Average Closing Price.
 
    (b) Each share of Company Common Stock held in the Company's treasury
  immediately prior to the Effective Time (the "EXCLUDED SHARES") shall, at
  the Effective Time, by virtue of the Merger, be canceled without payment of
  any consideration therefor and without any conversion thereof.
 
    (c) In the event Parent changes the number of shares of Parent Common
  Stock issued and outstanding prior to the Effective Time as a result of a
  stock split, stock dividend, or similar recapitalization with respect to
  such stock and the record date therefor (in the case of a stock dividend)
  or the effective date thereof (in the case of a stock split or similar
  recapitalization for which a record date is not established) shall be after
  the Exchange Ratio has been finally determined and prior to the Effective
  Time, the Exchange Ratio shall be appropriately adjusted to reflect the
  effects of such stock split, stock dividend or recapitalization. In the
  event Parent changes the number of shares of Parent Common Stock issued and
  outstanding prior to the Effective Time as a result of a stock split, stock
  dividend, or similar recapitalization with respect to such stock and the
  record date therefor (in the case of a stock dividend) or the effective
  date thereof (in the case of a stock split or similar recapitalization for
  which a record date is not established) shall be prior to the date on which
  the Exchange Ratio is finally determined, the Average Closing Price, the
  Minimum Average Closing Price, the Maximum Average Closing Price and the
  Threshold Price (as hereinafter defined) shall be appropriately adjusted to
  reflect the effects of such stock split, stock dividend or
  recapitalization.
 
                                      A-2
<PAGE>
 
  SECTION 3.02. CONVERSION OF ACQUISITION SUB COMMON STOCK. Each share of
common stock, par value $.01 per share, of Acquisition Sub (the "ACQUISITION
SUB COMMON STOCK") issued and outstanding at the Effective Time shall, at the
Effective Time by virtue of the Merger and without any action on the part of
the holder thereof, be converted into and exchangeable for one fully paid and
nonassessable share of the common stock of the Surviving Corporation
("SURVIVING CORPORATION COMMON STOCK"). From and after the Effective Time,
each outstanding certificate theretofore representing shares of Acquisition
Sub Common Stock shall be deemed for all purposes to evidence ownership of,
and to represent the number of shares of, Surviving Corporation Common Stock
into which such shares of Acquisition Sub Common Stock shall have been
converted.
 
  SECTION 3.03. FRACTIONAL SHARES. Notwithstanding any other provision of this
Agreement, each holder of shares of Company Common Stock exchanged pursuant to
the Merger who would otherwise have been entitled to receive a fraction of a
share of Parent Common Stock (after taking into account all certificates
delivered by such holder) shall receive, in lieu thereof, cash (without
interest) in an amount equal to such fractional part of a share of Parent
Common Stock multiplied by the market value of one share of Parent Common
Stock at the Effective Time. The market value of one share of Parent Common
Stock at the Effective Time shall be the last sale price of such common stock
on NASDAQ (as reported by The Wall Street Journal or, if not reported thereby,
any other authoritative source selected by Parent) on the last trading day
preceding the Effective Time. No such holder will be entitled to dividends,
voting rights, or any other rights as a stockholder in respect of any
fractional shares.
 
  SECTION 3.04. EXCHANGE PROCEDURES.
 
    (a) Prior to the Effective Time, the Company and Parent jointly shall
  select a bank or trust company to act as exchange agent in the Merger (the
  "EXCHANGE AGENT").
 
    (b) As soon as reasonably practicable after the Effective Time, Parent
  shall mail or cause the Exchange Agent to mail to each holder of record
  entitled to the Merger Consideration, (i) a form of letter of transmittal
  (which shall specify that delivery shall be effected, and risk of loss and
  title to the certificates which immediately prior to the Effective Time
  represented outstanding Shares (the "CERTIFICATES") shall pass, only upon
  proper delivery of the Certificates to the Surviving Corporation, and shall
  be in such form and have such other provisions as the Surviving Corporation
  reasonably may specify) and (ii) instructions for use in effecting the
  surrender of the Certificates in exchange for consideration provided in
  SECTION 3.01 (the "MERGER CONSIDERATION") to which such holder is entitled.
  Upon the proper surrender of a Certificate to the Exchange Agent, together
  with such letter of transmittal and any additional documentation as Parent
  may reasonably require, the holder of such Certificate shall be entitled to
  receive in exchange therefor the Merger Consideration, together with all
  undelivered dividends or distributions in respect of the shares of Parent
  Common Stock so issuable (without interest thereon), and the Certificate so
  surrendered shall forthwith be canceled. If any Merger Consideration is to
  be paid to a person other than the person in whose name the surrendered
  Certificate is registered, it shall be a condition of payment of such
  Merger Consideration that the Certificate so surrendered shall be promptly
  endorsed or otherwise in proper form for transfer and that the person
  requesting such payment shall pay any transfer or other taxes required by
  reason of the payment to a person other than the registered holder of the
  surrendered Certificate or established to the satisfaction of Parent that
  such tax has been paid or is not applicable.
 
    (c) Until surrendered in accordance with the provisions of this SECTION
  3.04, from and after the Effective Time, each Certificate (other than
  Certificates representing Excluded Shares) shall represent for all purposes
  only the right to receive, upon such surrender, the Merger Consideration
  into which the Shares represented by such Certificates shall have been
  converted pursuant to SECTION 3.01, and shall cease to have any rights with
  respect to the shares of Company Common Stock formerly represented thereby,
  except as otherwise provided herein or by law.
 
    (d) Notwithstanding the foregoing, none of Parent, the Surviving
  Corporation or the Exchange Agent shall be liable to any person in respect
  of retained Company Common Stock (or dividends or distributions with
  respect thereto) for any amount delivered to a public official pursuant to
  applicable abandoned property, escheat or similar laws.
 
                                      A-3
<PAGE>
 
    (f) Parent shall be entitled to deduct and withhold from the Merger
  Consideration otherwise payable pursuant to this Agreement to any holder of
  shares of Company Common Stock such amounts as Parent is required to deduct
  and withhold with respect to the making of such payment under the Internal
  Revenue Code of 1986, as amended (the "CODE"), or any provision of state,
  local or foreign tax law. To the extent that amounts are so withheld by
  Parent, such withheld amounts shall be treated for all purposes of this
  Agreement as having been paid to the holder of the shares of Company Common
  Stock in respect of which such deduction and withholding was made by
  Parent.
 
  SECTION 3.05. STOCK TRANSFER BOOKS. At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of transfers of Company Common Stock thereafter on the records of
the Company.
 
  SECTION 3.06. NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. The
Merger Consideration delivered upon the surrender of a certificate
representing Shares in accordance with the terms hereof shall be deemed to
have been issued in full satisfaction of all rights pertaining to such Shares,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of Shares which were outstanding immediately prior to
the Effective Time. If, after the Effective Time, Certificates are presented
to the Surviving Corporation for any reason, they shall be canceled and
exchanged as provided in this ARTICLE III.
 
  SECTION 3.07. LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent
shall pay in exchange for such lost, stolen or destroyed Certificates, upon
the making of an affidavit of that fact by the holder thereof and delivery of
bond in such sum as it may reasonably direct as indemnity against any claim
that may be made against Parent, the Surviving Corporation or any stockholder
of Parent, the Surviving Corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed, the Merger
Consideration attributable to such Certificates as may be required pursuant to
SECTION 3.04.
 
  SECTION 3.08. COMPANY STOCK OPTIONS AND WARRANTS.
 
    (a) At the Effective Time, each option and warrant granted by the Company
  to purchase shares of Company Common Stock, which is outstanding
  immediately prior thereto (an "OPTION" or, collectively, the "OPTIONS"),
  granted by the Company under the Company's 1992, 1993 or 1996 Incentive
  Stock Option Plans or the Officers' Contingent Stock Option Plan
  (collectively, the "COMPANY STOCK OPTION PLANS") or the Non-Employee
  Directors' Warrant Plan or otherwise, which are outstanding at the
  Effective Time, whether or not exercisable, shall be converted into and
  become rights with respect to Parent Common Stock, and Parent shall assume
  each Option, in accordance with the terms of the Company Stock Option Plan
  and stock option or warrant agreement by which it is evidenced, except that
  from and after the Effective Time, (i) Parent and its Compensation
  Committee shall be substituted for the Company and the Committee of the
  Company's Board of Directors (including, if applicable, the entire Board of
  Directors of the Company) administering such the Company Stock Option Plan,
  (ii) each Option assumed by Parent may be exercised solely for shares of
  Parent Common Stock (or cash, if so provided under the terms of such
  Option), (iii) the number of shares of Parent Common Stock subject to such
  Option shall be equal to the number of whole shares (rounded down to the
  nearest whole share) of Company Common Stock subject to such Option
  immediately prior to the Effective Time multiplied by the Exchange Ratio,
  and (iv) the per share exercise price under each such Option shall be
  adjusted by dividing the per share exercise price under each such Option by
  the Exchange Ratio and rounding up to the nearest cent. Notwithstanding the
  provisions of clauses (iii) and (iv) of the first sentence of this SECTION
  3.08(a), each Option which is an "incentive stock option" shall be adjusted
  as required by Section 424 of the Code, and the regulations promulgated
  thereunder, so as not to constitute a modification, extension or renewal of
  such Option, within the meaning of Section 424(h) of the Code.
 
    (b) Prior to the Effective Time, the Company shall use its reasonable
  best efforts to obtain all necessary consents or releases from holders of
  Options under any of the Company Stock Option Plans or the Non-
 
                                      A-4
<PAGE>
 
  Employee Directors' Warrant Plan or otherwise and take all such other
  lawful action as may be necessary to give effect to the transactions
  contemplated by this Section (except for such action that may require the
  approval of the Company's stockholders).
 
                                  ARTICLE IV.
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
  The Company hereby represents and warrants to Parent as follows:
 
  SECTION 4.01. ORGANIZATION AND STANDING.
 
    (a) Each of the Company and its Subsidiaries (as hereinafter defined) is
  a corporation duly organized, validly existing, and in good standing under
  the laws of the jurisdiction of its incorporation, and has the full
  corporate power and authority to carry on its business in the places as it
  is now being conducted and to own and lease the properties and assets which
  it now owns or leases, except where the failure of same will not in any
  case result in a Material Adverse Effect. The Company and each of its
  Subsidiaries is now duly qualified to transact business and in good
  standing as a foreign corporation in all jurisdictions in which the
  character of the property owned or leased by it and the nature of the
  business conducted by it require such qualification, except where failure
  to be qualified could not reasonably be expected to have a Material Adverse
  Effect. For purposes of this Agreement, a "SUBSIDIARY" of any person is any
  corporation, partnership, joint venture or other legal entity of which a
  majority of all outstanding shares of capital stock or other equity
  interests (the holders of which are ordinarily and generally entitled to
  vote for the election of the board of directors or other governing body
  thereof) is owned, directly or indirectly, by such person (either alone or
  through or together with any other Subsidiary).
 
    (b) True, correct and complete copies of the Certificate of
  Incorporation, certified by the Secretary of State of the State of
  Delaware, and By-Laws of the Company are attached hereto as SCHEDULE
  4.01(b).
 
  SECTION 4.02. AUTHORITY AND STATUS.
 
    (a) The Company has requisite corporate power and authority to execute
  and deliver this Agreement and to consummate the transactions contemplated
  hereby.
 
    (b) This Agreement has been approved by the Board of Directors of the
  Company in accordance with the GCL and except for the approval of the
  stockholders of the Company, no other corporate proceeding on the part of
  the Company is necessary to authorize this Agreement or to consummate the
  transactions contemplated hereby. The affirmative vote of the holders of a
  majority of the outstanding shares of Company Common Stock approving this
  Agreement is the only vote of the holders of any class or series of the
  Company's capital stock necessary to approve this Agreement and the
  transactions contemplated by this Agreement.
 
    (c) This Agreement has been duly and validly executed and delivered by
  the Company and is a valid and binding agreement of the Company,
  enforceable against the Company in accordance with its terms, except as
  such enforceability may be limited by bankruptcy, insolvency,
  reorganization, fraudulent conveyance, moratorium or similar laws in effect
  now or hereafter relating to creditors' rights generally, and by equitable
  principles (whether considered in a proceeding at law or in equity).
 
  SECTION 4.03. CAPITALIZATION.
 
    (a) The authorized capital stock of the Company consists of (i) fifteen
  million (15,000,000) shares of common stock, par value $.01 per share, of
  which 8,997,105 Shares were issued and outstanding and 72,000 Shares were
  held in the Company's treasury as of October 31, 1997; (ii) one million
  (1,000,000) shares of preferred stock, par value $.01 per share, of which
  none are outstanding or held in the Company's treasury as of October 31,
  1997; and (iii) as of October 31, 1997, 777,851 and 136,832 Shares reserved
  for future issuance pursuant to outstanding stock options and warrants
  under the Company Stock Option Plans and the Non-Employee Directors'
  Warrant Plan together with certain other warrant awards, respectively. All
  of the issued and outstanding capital stock of the Company is validly
  issued, fully paid and non-assessable.
 
                                      A-5
<PAGE>
 
  All of the outstanding capital stock of each of the Company's Subsidiaries
  is owned directly or indirectly by the Company free and clear of all
  security interests, liens, pledges, claims, charges, escrows, encumbrances,
  mortgages, indentures or easements (collectively, "LIENS") of any nature,
  except as disclosed on SCHEDULE 4.03(a).
 
    (b) Except as set forth in SECTION 4.03(a) or on SCHEDULE 4.03(b), there
  are no other shares of capital stock of the Company or any of its
  Subsidiaries, or securities convertible into or exchangeable or exercisable
  for shares of capital stock of the Company or any of its Subsidiaries,
  outstanding, and there are no outstanding options, warrants, rights,
  contracts, commitments, understandings, arrangements or claims of any
  character by which the Company or any of its Subsidiaries is or may become
  bound to issue, transfer, sell, repurchase or otherwise acquire or retire
  any shares of capital stock or other ownership interest of the Company or
  any of its Subsidiaries, or any securities convertible into or exchangeable
  or exercisable for any such shares or other ownership interest.
 
    (c) SCHEDULE 4.03(c) sets forth a complete and accurate list of entities
  (each, a "MINORITY AFFILIATE"), other than the Company's Subsidiaries, of
  which the Company owns equity securities (as defined in Rule 3a-11
  promulgated under the Exchange Act (as hereinafter defined)), including, as
  to each Minority Affiliate, its name, its jurisdiction of incorporation,
  formation or organization and its capitalization (including the identity of
  each stockholder or owner of equity securities or other securities and the
  number of shares or other securities held thereby). None of the Company or
  any of its Subsidiaries has entered into any commitment, contract or
  agreement to provide equity financing to any other person or entity.
 
  SECTION 4.04. NO CONFLICT, REQUIRED FILINGS AND CONSENTS.
 
    (a) The exhibit index to the Company's most recently filed Annual Report
  on Form 10-K, and Quarterly Reports on Form 10-Q and any Current Reports on
  Form 8-K filed since such Annual Report on Form 10-K, as supplemented by
  SCHEDULE 4.04(a), include each agreement, contract or other instrument
  (including all amendments thereto) to which the Company or any of its
  Subsidiaries is a party or by which any of them is bound and which would be
  required pursuant to the Securities Exchange Act of 1934, as amended (the
  "EXCHANGE ACT") and the rules and regulations thereunder to be filed as an
  exhibit to an Annual Report on Form 10-K, a Quarterly Report on Form 10-Q
  or a Current Report on Form 8-K. The Company has made available to Parent
  on or prior to the date hereof true, correct and complete copies in all

  respect of any Tax pending between the Company or any Subsidiary and any
  taxing authority; (iv) neither the Company nor any Subsidiary will be
  required to include any adjustment in taxable income for any Tax period
  following the Closing under Section 481(c) of the Code (or any similar
  provision of the Tax laws of any jurisdiction) as a result of a change in
  method of accounting for a Tax period prior to the Closing or pursuant to
  the provisions of any agreement entered into with any taxing authority with
 
                                     A-10

  property holding corporation, as defined under Section 897(c)(2) of the

  and Taxes being contested) in accordance with generally accepted accounting
  principles applied on a consistent basis, and the accrual and reserves for
  Taxes (including deferred taxes) reflected in the books and records of
  Parent as at the last day of Parent's most recently completed fiscal month

  Parent nor any Subsidiary will be required to include any adjustment in
  taxable income for any Tax period following the Closing under Section
  481(c) of the Code (or any similar provision of the Tax laws of any
  jurisdiction) as a result of a change in method of accounting for a Tax
  period prior to the Closing or pursuant to the provisions of any agreement
  entered into with any taxing authority with regard to the Tax liability of
  Parent or any Subsidiary for any Tax period prior to the Closing; and (v)
  all material Taxes that Parent or any Subsidiary is, or was, required by
  law to withhold or collect have been duly withheld or collected and, to the

statutory liability, or otherwise form the basis of any claim, action, suit or
proceeding, against Parent or any of its Subsidiaries based on or resulting

disposal, transport or handling, or the emission, discharge or release into
the environment, of any pollutant, contaminant or hazardous or toxic material

  FURTHER, that the Company shall keep Parent informed, on a reasonably
  current basis, as to the status and details of any such consideration,

  an Acquisition Proposal. Such notice to Parent shall be made orally and in
  writing, shall indicate whether the Company is providing or intends to

  6.03(c) in order to discharge properly the directors' fiduciary duties to
  the Company's stockholders, then, PROVIDED that such person has executed a
  confidentiality agreement substantially similar to the one then in effect

  the Company shall not be entitled to exercise any termination rights under
  clause (i) or (ii) of this SECTION 9.01(d) unless (x) any action of the
  Board of Directors of the Company referred to in either such clause is
  required to be taken by the Board of Directors in order to properly

  acquire more than 15% of the outstanding shares, whether from the Company
  or pursuant to a tender offer or exchange offer or otherwise, (ii) any

    (e) by the Company, if: (i) the Board of Directors of Parent shall have
  recommended to the stockholders of Parent (x) any acquisition or proposed
  acquisition of Parent by a merger, consolidation or other business
  combination (including any so-called "merger of equals" and whether or not
  the Company is the entity surviving any such merger or business
  combination) in which the consideration to be received by Parent
  stockholders in such business combination shall be other than cash, (y) any
  liquidation or dissolution of Parent, or (z) any transaction or series of
  transactions in which Third Parties would acquire substantially all of the

  of any representation, warranty, covenant or agreement on the part of the
  other set forth in this Agreement, which breach has not been cured within
  30 days following receipt by the breaching party of written notice of such
  breach, in any case such that the conditions set forth in SECTIONS 8.02 or
  8.03, as the case may be, would be incapable of being satisfied by April
  30, 1998 (PROVIDED that the right to terminate this Agreement under this
  SECTION 9.01(h) shall not be available to any party who is itself in
  material breach of any of its representations, warranties, covenants or
  agreements set forth in this Agreement, such that the conditions set forth
  in SECTIONS 8.02 OR 8.03, as the case may be, would be incapable of being
  satisfied by April 30, 1998); or
 
    (i) by the Company, if its Board of Directors so determines by a vote of
  a majority of the members of its entire Board, at any time during the
  three-business-day period commencing on the Determination Date, if the
  Average Closing Price shall be less than $24.00 (the "THRESHOLD PRICE");
  subject, however, to the following three sentences. If the Company elects
  to exercise its termination right pursuant to this SECTION 9.01(i), it
  shall give prompt written notice thereof to Parent (provided that such
  notice of election to terminate may be withdrawn at any time within the
  three-business-day period referenced in the following sentence). During the
  three-business-day period commencing with its receipt of such notice,
  Parent shall have the option, in its sole discretion, to elect to increase
  the Exchange Ratio to equal the quotient obtained by dividing (x) the
  product of the Threshold Price and the Exchange Ratio (as then in effect)
  by (y) the Average Closing Price. If Parent makes an election contemplated
  by the preceding sentence within such three-business-day period, it shall
  give prompt written notice to the Company of such election and the revised
  Exchange Ratio, whereupon no termination shall have occurred pursuant to
  this SECTION 9.01(i) and this Agreement shall remain in effect in
  accordance with its terms (except as the Exchange Ratio shall have been so
  modified), and any references in this Agreement to "Exchange Ratio" shall
  thereafter be deemed to refer to the Exchange Ratio as adjusted pursuant to
  this SECTION 9.01(i).

  become void and there shall be no liability on the part of any party hereto
  or any of its affiliates, directors, officers or stockholders, subject to
  the provisions of SECTION 9.02(b) and SECTION 9.02(c), and nothing herein
  shall relieve any party from liability for any breach hereof occurring
  prior to termination. The Confidentiality Letter shall survive termination
  of this Agreement as set forth therein.
 
    (b) Notwithstanding anything to the contrary contained in this Agreement,
  in the event that this Agreement is terminated by either party for any
  reason, except as provided in clauses (i) and (ii) below, the Company shall
  pay to Parent an amount equal to $9,500,000 (the "PARENT FEE") plus all

      claims made by stockholders of the Company or any Third Party
      proposing an Alternative Transaction), 8.01(d), 8.01(e), 8.01(f),
      8.03(a), 8.03(b) or 8.03(c),
 
        (4) by either party pursuant to SECTION 9.01(b) solely as a result
      of the failure to satisfy the condition set forth in SECTION
      8.01(a), but only if the stockholders of the Company have adopted
      this Agreement and the stockholders of Parent have not approved the
      issuance of shares of Parent Common Stock in the Merger or any other
      aspect of the Merger which is submitted for their approval at the
      Parent Stockholders Meeting,
 
        (5) by Parent pursuant to SECTION 9.01(b) solely as a result of

      8.01(b), 8.01(d), 8.01(e), 8.01(f), 8.02(e) or 8.02(f),
 
        (6) by either party pursuant to SECTION 9.01(c) if any such
      injunction results from claims made by stockholders of the Company
      or any Third Party proposing an Alternative Transaction, or
 
        (7) by the Company pursuant to SECTION 9.01(g); and
 
      (ii) the Company shall not be obligated to pay the Parent Fee but
    shall only be obligated to reimburse Parent for the amount of Parent
    Expenses incurred by it up to a maximum of $1,000,000 if this Agreement
    is terminated
 
        (1) by Parent pursuant to SECTION 9.01(b) solely as a result of
      the failure to satisfy the condition set forth in SECTION 8.02(c)
      (other than as a result of the Company's breach of a representation
      or warranty in the UK Purchase Agreement or the Company's failure to
      fulfill any of its material obligations in the UK Purchase
      Agreement) or the condition set forth in SECTION 8.02(d), or
 
        (2) by the Company pursuant to SECTION 9.01(g) if there shall have
      occurred a Material Adverse Effect with respect to the Company after
      the date of this Agreement and prior to the date on which Parent's
      Board of Directors withdrew, modified or changed its approval or
      recommendation of this Agreement or the Merger in a manner adverse
      to the Company.
 
    (c) Notwithstanding anything to the contrary contained in this Agreement,

    Transaction with Parent), 8.03(a), 8.03(b) or 8.03(c),
 
      (iii) by either party pursuant to SECTION 9.01(b) solely as a result
    of the failure to satisfy the condition set forth in SECTION 8.01(a),
    but only if the stockholders of the Company have adopted this Agreement
    and the stockholders of Parent have not approved the issuance of shares
    of Parent Common Stock in the Merger or any other aspect of the Merger
    which is submitted for their approval at the Parent Stockholders
    Meeting,
 
      (iv) by either party pursuant to SECTION 9.01(c) if any such
    injunction results from claims made by stockholders of Parent or any
    Third Party proposing an Alternative Transaction with Parent, or
 
      (v) by the Company pursuant to SECTION 9.01(g) (unless there shall
    have occurred a Material Adverse Effect with respect to the Company
    after the date of this Agreement and prior to the date on which
    Parent's Board of Directors withdrew, modified or changed its approval
    or recommendation of this Agreement or the Merger in a manner adverse

  made by wire transfer of immediately available funds to an account
  designated by the Recipient or its designee in the notice of demand for
  payment delivered pursuant to this SECTION 9.02(d).
 
    (e) The parties acknowledge that the loss to either party resulting from
  breach of this Agreement by the other party or other failure of the Merger
  to be consummated is not susceptible of ready measurement and, therefore,
  that the payments provided in this SECTION 9.02 are intended by the parties
  to constitute liquidated damages for any breach by a party of the terms of
  this Agreement, and not a penalty.
 
  SECTION 9.03. FEES AND EXPENSES. All fees and expenses incurred in
connection with this Agreement and the transactions contemplated hereby shall
be paid by the party incurring such expenses, whether or not the Merger is

                               AFFILIATE LETTER
 
Premiere Technologies, Inc.
3399 Peachtree Road NE
Lenox Building, Suite 400
Atlanta, Georgia 30326
 
Attention:Patrick G. Jones
     Executive Vice President Finance and Legal
 
Gentlemen:
 
  The undersigned is a stockholder of Xpedite Systems, Inc. (the "COMPANY"), a
Delaware corporation, and will become a stockholder of Premiere Technologies,
Inc. ("PARENT"), a Georgia corporation, pursuant to the transactions described
in the Agreement and Plan of Merger, dated as of November 13, 1997 (the
"AGREEMENT"), by and among Parent, Nets Acquisition Corp. ("ACQUISITION SUB")
and the Company. Under the terms of the Agreement, Acquisition Sub will be
merged into and with the Company (the "MERGER"), and the shares of the $.01
par value common stock of the Company ("COMPANY COMMON STOCK") will be
converted into and exchanged for shares of the $.01 par value common stock of
Parent ("PARENT COMMON STOCK"). This Affiliate Letter represents an agreement
between the undersigned and Parent regarding certain rights and obligations of
the undersigned in connection with the shares of Parent to be received by the
undersigned as a result of the Merger.
 
  In consideration of the Merger and the mutual covenants contained herein,
the undersigned and Parent hereby agree as follows:
 
  1. Affiliate Status. The undersigned understands and agrees that as to the
Company the undersigned may be deemed to be an "affiliate" under Rule 145(c)
as defined in Rule 405 of the Rules and Regulations of the Securities and
Exchange Commission ("SEC") under the Securities Act of 1933, as amended
("SECURITIES ACT"), and the undersigned anticipates that the undersigned may
be deemed to be such an "affiliate" both at the time of the Agreement is
submitted to the stockholders of the Company for their consideration and
adoption and at the effective time of the Merger.
 
  2. Initial Restrictions on Dispositions. During the 30 days immediately
preceding the Effective Time of the Merger, the undersigned agrees that the
undersigned will not sell, transfer, or otherwise dispose of the undersigned's
interests in, or reduce the undersigned's risk relative to, any of the shares
of the Company Common Stock beneficially owned by the undersigned. The
undersigned agrees that the undersigned will not sell, transfer, or otherwise
dispose of the undersigned's interests in, or reduce the undersigned's risk
relative to, any of the shares of Parent Common Stock into which the
undersigned's shares of the Company Common Stock are converted upon
consummation of the Merger until such time as Parent notifies the undersigned
that the requirements of SEC Accounting Series Release Nos. 130 and 135 ("ASR
130 AND 135") have been met. The undersigned understands that ASR 130 and 135
relate to publication of financial results of post-Merger combined operations
of Parent and the Company. Parent agrees that it will publish such results as
soon as practicable after completion of the first full calendar month after
consummation of the Merger containing the required period of post-Merger
combined operations and that it will notify the undersigned promptly following
such publication. Notwithstanding anything in this Agreement to the contrary,
the undersigned shall be permitted to transfer the shares of Company Common
Stock owned by it in connection with distributions of securities by the
undersigned to its equity holders on a pro rata basis in accordance with the
respective interests of such equity holders in the undersigned; provided such
transfer does not adversely affect the ability of Parent to treat the Merger
as a pooling of interests for accounting purposes or for the Merger to qualify
as a tax-free reorganization; and provided further that the undersigned shall
have given Parent prior written notice of such proposed transfer and shall
have supplied to Parent and its representatives such information regarding the
proposed transfer as Parent or such
 
                                     A-38
<PAGE>
 
representatives shall request to permit Parent and such representatives to
confirm that such transfer will not adversely affect the ability of Parent to
treat the Merger as a pooling of interests for accounting purposes or for the
Merger to qualify as a tax-free reorganization.
 
  3. Covenants and Warranties of Undersigned. The undersigned represents,
warrants and agrees that:
 
    (a) The Parent Common Stock received by the undersigned as a result of
  the Merger will be taken for the undersigned's own account and not for
  others, directly or indirectly, in whole or in part.
 
    (b) The undersigned agrees not to make any sale, transfer of other
  disposition of the Parent Common Stock received by the undersigned in
  connection with the Merger in violation of the Securities Act or the rules
  and regulations promulgated thereunder. Parent has informed the undersigned
  that any distribution by the undersigned of Parent Common Stock has not
  been registered under the Securities Act and that shares of Parent Common
  Stock received pursuant to the Merger can only be sold by the undersigned
  (1) following registration under the Securities Act, or (2) in conformity
  with the volume and other requirements of Rule 145(d) promulgated by the
  SEC as the same now exist or may hereafter be amended, or (3) in the
  opinion of counsel reasonably acceptable to the Company, or pursuant to a
  "no action" letter obtained by the undersigned from the staff of the
  Commission, such sale, transfer or other disposition is otherwise exempt
  from registration under the Securities Act. The undersigned understands
  that, except as provided in the Agreement, Parent is under no obligation to
  file a registration statement with the SEC covering the disposition of the
  undersigned's shares of Parent Common Stock or to take any other action
  necessary to make compliance with an exemption from such registration
  available.
 
    (c) The undersigned is aware that Parent intends to treat the Merger as a
  tax-free reorganization under Section 368 of the Internal Revenue Code (the
  "CODE") for federal income tax purposes. The undersigned agrees to treat
  the transaction in the same manner as Parent for federal income tax
  purposes. The undersigned acknowledges that Section 1.368-1(b) of the
  Income Tax Regulations requires "continuity of interest" in order for the
  Merger to be treated as tax-free under Section 368 of the Code. This
  requirement is satisfied if, taking into account those Company stockholders
  who receive cash in exchange for their stock, who receive cash in lieu of
  fractional shares, or who dissent from the Merger, there is no plan or
  intention on the part of the Company stockholders to sell or otherwise
  dispose of the Parent Common Stock to be received in the Merger that will
  reduce such stockholders' ownership to a number of shares having, in the
  aggregate, a value at the time of the merger of less than 50% of the total
  fair market value of the Company Common Stock outstanding immediately prior
  to the Merger. The undersigned has no prearrangement, plan or intention to
  sell or otherwise dispose of an amount of the undersigned's Parent Common
  Stock to be received in the Merger which would cause the foregoing
  requirement not to be satisfied.
 
  4. Restrictions on Transfer. The undersigned understands and agrees that
stop transfer instructions with respect to the shares of Parent Common Stock
received by the undersigned pursuant to the Merger will be given to Parent's
Transfer Agent and that there will be placed on the certificates for such
shares, or shares issued in substitution thereof, a legend stating in
substance:
 
  "The shares represented by this certificate were issued pursuant to a
  business combination which is accounted for as a "pooling of interests" and
  may not be sold, nor may the owner thereof reduce the owner's risks
  relative thereto in any way, until such time as Premiere Technologies, Inc.
  ("Parent") has published the financial results covering at least 30 days of
  combined operations after the effective date of the merger through which
  the business combination was effected. In addition, the shares represented
  by this certificate may not be sold, transferred or otherwise disposed of
  except or unless (1) covered by an effective registration statement under
  the Securities Act of 1933, as amended, (2) in accordance with (i) Rule
  145(d) (in the case of shares issued to an individual who is not an
  affiliate of Parent) or (ii) Rule 144 (in the case of shares issued to an
  individual who is an affiliate of Parent) of the Rules and Regulations of
  such Act, or (3) in accordance with a legal opinion satisfactory to counsel
  for Parent that such sale or transfer is otherwise exempt from the
  registration requirements of such Act."
 
                                     A-39
<PAGE>
 
Such legend will also be placed on any certificate representing Parent
securities issued subsequent to the original issuance of the Parent Common
Stock pursuant to the Merger as a result of any transfer of such shares or any
stock dividend, stock split, or other recapitalization as long as the Parent
Common Stock issued to the undersigned pursuant to the Merger has not been
transferred in such manner to justify the removal of the legend therefrom.
Upon the request of the undersigned, Parent shall cause the certificates
representing the shares of Parent Common Stock issued to the undersigned in
connection with the Merger to be reissued free of any legend relating to
restrictions on transfer by virtue of ASR 130 and 135 as soon as practicable
after the requirements of ASR 130 and 135 have been met. In addition, if the
provisions of Rules 144 and 145 are amended to eliminate restrictions
applicable to the Parent Common Stock received by the undersigned pursuant to
the Merger, or at the expiration of the restrictive period set forth in Rule
145(d), Parent, upon the request of the undersigned, will cause the
certificates representing the shares of Parent Common Stock issued to the
undersigned in connection with the Merger to be reissued free of any legend
relating to the restrictions set forth in Rules 144 and 145(d) upon receipt by
Parent of an opinion of its counsel to the effect that such legend may be
removed.
 
  5. Understanding of Restrictions on Dispositions. The undersigned has
carefully read the Agreement and this Affiliate Agreement and discussed their
requirements and impact upon the undersigned's ability to sell, transfer, or
otherwise dispose of the shares of Parent Common Stock received by the
undersigned, to the extent the undersigned believes necessary, with the
undersigned's counsel or counsel for the Company.
 
  6. Filing of Reports by Parent. Parent agrees, for a period of three years
after the effective date of the Merger, to file on a timely basis all reports
required to be filed by it pursuant to Section 13 of the Securities Exchange
Act of 1934, as amended, so that the public information provisions of Rule
145(d) promulgated by the SEC as the same are presently in effect will be
available to the undersigned in the event the undersigned desires to transfer
any shares of Parent Common Stock issued to the undersigned pursuant to the
Merger.
 
  7. Transfer Under Rule 145(d). If the undersigned desires to sell or
otherwise transfer the shares of Parent Common Stock received by the
undersigned in connection with the Merger at any time during the restrictive
period set forth in Rule 145(d), the undersigned will provide the necessary
representation letter to the transfer agent for Parent Common Stock together
with such additional information as the transfer agent may reasonably request.
If Parent's counsel concludes that such proposed sale or transfer complies
with the requirements of Rule 145(d), Parent shall cause such counsel to
promptly provide such opinions as may be necessary to Parent's Transfer Agent
so that the undersigned may complete the proposed sale or transfer, and Parent
shall promptly take such other actions as may reasonably be required in order
to effectuate such sale or transfer.
 
  8. Acknowledgments. The undersigned recognizes and agrees that the foregoing
provisions also apply to all shares of the capital stock of the Company and
Parent that are deemed to be beneficially owned by the undersigned pursuant to
applicable federal securities laws, which the undersigned agrees may include,
without limitation, shares owned or held in the name of (i) the undersigned's
spouse, (ii) any relative of the undersigned or of the undersigned's spouse
who has the same home as the undersigned, (iii) any trust or estate in which
the undersigned, the undersigned's spouse, and any such relative collectively
own at least a 10% beneficial interest or of which any of the foregoing serves
as trustee, executor, or in any similar capacity, and (iv) any corporation or
other organization in which the undersigned, the undersigned's spouse and any
such relative collectively own at least 10% of any class of equity securities
or of the equity interest. The undersigned further recognizes that, in the
event that the undersigned is a director or officer of Parent or becomes a
director or officer of Parent upon consummation of the Merger, among other
things, any sale of Parent Common Stock by the undersigned within a period of
less than six months following the effective time of the Merger may subject
the undersigned to liability pursuant to Section 16(b) of the Securities
Exchange Act of 1934, as amended.
 
  9. Miscellaneous. This Affiliate Agreement is the complete agreement between
Parent and the undersigned concerning the subject matter hereof. Any notice
required to be sent to any party hereunder shall be sent by registered or
certified mail, return receipt requested, using the addresses set forth herein

                             STOCKHOLDER AGREEMENT
 
  STOCKHOLDER AGREEMENT dated as of November 13, 1997, among the person whose
name appears on Schedule 1 (the "STOCKHOLDER"), Xpedite Systems, Inc., a
Delaware corporation (the "COMPANY"), and Premiere Technologies, Inc., a
Georgia corporation ("PARENT").
 
  WHEREAS, Parent proposes to enter into a Merger Agreement dated as of the
date hereof (as amended from time to time, the "MERGER AGREEMENT"; capitalized
terms used but not defined herein shall have the meanings set forth in the
Merger Agreement, whether or not such Merger Agreement shall be in effect from
time to time) with the Company which provides, among other things, that Nets
Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of
Parent, will merge with and into the Company pursuant to the merger
contemplated by the Merger Agreement (the "MERGER");
 
  WHEREAS, as of the date hereof, the Stockholder beneficially owns the number
of shares of common stock, par value $.01 per share, of the Company ("COMPANY
COMMON STOCK") set forth on Schedule 1; and
 
  WHEREAS, as a condition to the willingness of Parent to enter into the
Merger Agreement, Parent has requested that the Stockholder agree, and in
order to induce Parent to enter into the Merger Agreement, the Stockholder has
agreed, to enter into this Agreement with respect to all the shares of Company
Common Stock now beneficially owned and of which the Stockholder may hereafter
acquire beneficial ownership (the "SHARES") and any other securities, if any,
which the Stockholder is entitled to vote at any meeting of stockholders of
the Company (the "OTHER SECURITIES").
 
  NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein, and intending to be legally bound hereby, the
parties hereto agree as follows:
 
                                   ARTICLE I
 
                               VOTING AGREEMENT
 
  SECTION 1.01 VOTING AGREEMENT. The Stockholder hereby agrees that, subject
to Schedule 1, at any meeting of the stockholders of the Company, however
called, or in connection with any written consent of the holders of shares of
Company Common Stock, the Stockholder shall vote (or cause to be voted) the
Shares and the Other Securities in favor of the Merger, the execution and
delivery by the Company of the Merger Agreement and the approval of the terms
thereof and each of the other actions contemplated by the Merger Agreement and
this Agreement and any actions required in furtherance thereof and hereof. The
Stockholder agrees that the Stockholder shall not enter into any agreement or
understanding with any person or entity the effect of which would be to
violate the provisions and agreements contained in this Section 1.01. The
Stockholder acknowledges receipt and review of a copy of the Merger Agreement.
 
  SECTION 1.02 IRREVOCABLE PROXY. The Stockholder hereby irrevocably appoints
Parent and each of its officers, as the Stockholder's attorney and proxy
pursuant to the provisions of Section 212(c) of the General Corporation Law of
the State of Delaware, with full power of substitution, to vote and otherwise
act (by written consent or otherwise) with respect to the Shares and the Other
Securities, which the Stockholder is entitled to vote at any meeting of
stockholders of the Company (whether annual or special and whether or not an
adjourned or postponed meeting) or consent in lieu of any such meeting or
otherwise, on the matters and in the manner specified in Section 1.01. THIS
PROXY AND POWER OF ATTORNEY IS IRREVOCABLE AND COUPLED WITH AN INTEREST. The
Stockholder hereby revokes all other proxies and powers of attorney with
respect to the Shares and the Other Securities that the Stockholder may have
heretofore appointed or granted, and no subsequent proxy or power of attorney
shall be given or written consent executed (and if given
 
                                     A-42
<PAGE>
 
or executed, shall not be effective) by the Stockholder with respect thereto.
All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the Stockholder and any obligation of the Stockholder
under this Agreement shall be binding upon the heirs, personal
representatives, successors and assigns of the Stockholder. The Shareholder
hereby affirms that the irrevocable proxy set forth in this SECTION 1.02 is
given in connection with the execution of the Merger Agreement, and that such
irrevocable proxy is given to secure the performance of the duties of the
Shareholder under this Agreement. The Shareholder hereby ratifies and confirms
all that such irrevocable proxy may lawfully do or cause to be done by virtue
hereof.

    (c) The execution and delivery of this Agreement by the Stockholder do

  rules and regulations of the Commission thereunder (the "SECURITIES ACT");
  and (ii) where the failure to obtain such consents, approvals,

  not reasonably be expected to materially impair the ability of the
  Stockholder to perform its obligations hereunder or to consummate the
  transactions contemplated hereby.
 
    (d) There is no suit, action, investigation or proceeding pending or, to
  the knowledge of the Stockholder, threatened against the Stockholder at law

  expected to materially impair the ability of the Stockholder to perform the
  Stockholder's obligations hereunder or to consummate the transactions
  contemplated hereby, and there is no judgment, decree, injunction, rule,
  order or writ of any Governmental Entity to which the Stockholder or the
  Stockholder's assets are subject that could reasonably be expected to

  Stockholder's obligations hereunder or to consummate the transactions
  contemplated hereby.

binding obligation of Parent, enforceable against Parent in accordance with
its terms.

  SECTION 6.01 SEVERABILITY. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any rule of law, or
public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal

negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner
in order that the terms of this Agreement remain as originally contemplated to
the fullest extent possible.
 
  SECTION 6.02 ENTIRE AGREEMENT. This Agreement constitutes the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior agreements and understandings, both written and oral,
among the parties with respect to the subject matter hereof.
 
  SECTION 6.03 COUNTERPARTS. This Agreement may be executed and delivered
(including by facsimile transmission) in one or more counterparts, and by the

not a party hereto.
 
  SECTION 6.08 SPECIFIC PERFORMANCE. Each of the parties hereto acknowledges

entitled to the remedy of specific performance of such agreement and
injunctive and other equitable relief in addition to any other remedy to which
they may be entitled, at law or in equity.
 
  SECTION 6.09 REMEDIES CUMULATIVE. All rights, powers and remedies provided

  SECTION 6.10 NO WAIVER. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon strict compliance by any
other party hereto with its obligations hereunder, and any custom or practice
of the parties at variance with the terms hereof, shall not constitute a
waiver by such party of its right to exercise any such or other right, power
or remedy or to demand such compliance.

  waives any objection based on FORUM NON CONVENIENS or any other objection
  to venue therein); PROVIDED, HOWEVER, that such consent to jurisdiction is
  solely for the purpose referred to in this subsection (b) and shall not be
  deemed to be a general submission to the jurisdiction of such court or in
  the State of Delaware other than for such purposes.
 
  SECTION 6.12 WAIVER OF JURY TRIAL. EACH OF PARENT, THE COMPANY AND THE
STOCKHOLDER HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR

  Registration under Section 2.2. Such request will specify the number of
  shares of Registrable Securities proposed to be sold. A registration will
  not count as a Demand Registration (x) if, due to the provisions of Section
  2.3, the number of Registrable Securities included in such registration is
  less than 85% of the Registrable Securities sought to be included in such
  registration and (y) until it has become effective.
 
    (b) Unless Parent shall otherwise consent in writing in response to a
  request made by the Large Stockholder, the offering of such Registrable
  Securities pursuant to such Demand Registration shall be in the form of an
  underwritten offering. Parent shall select the book-running and other
  managing Underwriters (which shall be nationally recognized firms) in
  connection with such offering and any additional investment bankers and
  managers to be used in connection with the offering.
 
    (c) Subject to the provisions of Section 2.3, other shareholders of
  Parent shall be entitled to include shares in the Demand Registration
  pursuant to any registration rights or other similar rights granted to them
  by Parent.
 
                                     A-49

  2.2. Piggyback Registration. If Parent proposes to file a registration
statement under the Securities Act with respect to an offering of Parent
Common Stock (i) for Parent's own account (other than (a) a registration
statement on Form S-4 or S-8 or relating solely to securities issued pursuant
to any benefit plan (or any substitute form that may be adopted by the
Commission), (b) a registration statement covering any method of distribution
which is not an underwritten public offering, or (c) a registration relating
to convertible securities of Parent including any underlying equity securities
or relating to any securities sold pursuant to a Rule 144A transaction) or
(ii) for the account of any of the holders of Parent Common Stock (other than
a registration where the intended method of disposition is not pursuant to an
underwritten public offering), then Parent shall give written notice of such
proposed filing to the Large Shareholder as soon as practicable (but in no
event less than ten days before the anticipated filing date), and such notice
shall offer, subject to the terms and conditions hereof, such Large
Shareholder the opportunity to register such Registrable Securities as such
Large Shareholder may request on the same terms and conditions as Parent's or
such holders' Parent Common Stock (a "Piggyback Registration"). Parent shall
have the right to terminate or withdraw any registration undertaken by it
under this Section 2.2 prior to the effectiveness of such registration whether
or not any Large Shareholder has elected to include securities in such
registration.
 
  2.3. Reduction of Offering. Notwithstanding anything contained herein, if
the managing Underwriter or Underwriters of an offering described in Section
2.1 or 2.2 shall advise Parent that (i) the size of the offering that Large
Shareholder, Parent and any other persons intend to make or (ii) the kind of
securities that Large Shareholder, Parent and such other persons intend to
include in such offering are such that the success of the offering would be
materially and adversely affected, then (A) if the size of the offering is the
basis of such Underwriter's advice, the amount of Registrable Securities to be
offered for the account of such Large Shareholder shall be reduced to the
extent necessary to reduce the total amount of securities to be included in
such offering to the amount recommended by such managing Underwriter or
Underwriters; provided that (x) in the case of a Demand Registration, the
amount of Registrable Securities to be offered for the account of such Large
Shareholder shall be reduced only after the amount of securities to be offered
for the account of Parent and such other persons has been reduced to zero
except and to the extent prohibited by the terms of any registration rights or
other agreement in effect with any of the Priority Holders, and (y) in the
case of a Piggyback Registration, if securities are being offered for the
account of persons other than Parent, then after all securities of the persons
requesting such registration have been included (the "Demand Shareholders"),
the proportion by which the amount of such Registrable Securities intended to
be offered for the account of such Large Shareholder is reduced shall not
exceed the proportion by which the amount of such securities intended to be
offered for the account of persons other than the Demand Shareholders is
reduced except and to the extent prohibited by the terms of any registration
rights or other agreement in effect with any of the Priority Holders; and (B)
if the combination of securities to be offered is the basis of such
Underwriter's advice, (x) the Registrable Securities to be included in such
offering shall be reduced as described in clause (A) above (subject to the
proviso in clause (A)), or (y) in the case of a Piggyback Registration, if the
actions described in sub-clause (x) of this clause (B) would, in the judgment
of the managing Underwriter, be insufficient to eliminate the adverse effect
that inclusion of the Registrable Securities requested to be included would
have on such offering, such Registrable Securities will be excluded from such
offering. If the managing underwriter has not limited the number of
Registrable Securities or other securities to be underwritten, Parent and
officers and directors of Parent may include its or their securities for its
or their own account in such registration if the managing underwriter so
agrees and if the number of Registrable Securities and other securities which
would otherwise have been included in such registration and underwriting will
not thereby be limited.
 
III.REGISTRATION PROCEDURES
 
  3.1. Filings; Information. Whenever a Large Shareholder requests that any
Registrable Securities be registered pursuant to Section 2.1 hereof, Parent
will use its commercially reasonable efforts to effect the registration of
such Registrable Securities as soon as reasonably practicable, and in
connection with any such request:
 
    (a) Parent will as soon as reasonably practicable prepare and file with
  the SEC a registration statement on any form for which Parent then
  qualifies and which counsel for Parent shall deem appropriate and
 
                                     A-50
<PAGE>
 
  available for the sale of the Registrable Securities to be registered
  thereunder in accordance with the intended method of distribution thereof,
  and use reasonable efforts to cause such filed registration statement to
  become and remain effective for a period of not less than 45 days; provided
  that if Parent shall furnish to such Large Shareholder a certificate signed
  by its Chairman, Chief Executive Officer, Chief Financial Officer or any
  Executive Vice President stating that in his or her good faith judgment it
  would be detrimental or otherwise disadvantageous to Parent or its
  shareholders for such a registration statement to be filed, or, in the case
  of an effective registration statement, for sales to be effected
  thereunder, Parent shall have a period of not more than 120 days within
  which to file such registration statement measured from the date of receipt
  of the request in accordance with Section 2.1 or, in the case of an
  effective registration statement, Parent shall be entitled to require such
  Large Shareholder to refrain from selling Registrable Securities under such
  registration statement for a period of up to 120 days. If Parent furnishes
  a notice under this paragraph at a time when a registration statement filed
  pursuant to this Agreement is effective, Parent shall extend the period
  during which such registration statement shall be maintained effective as
  provided in this Section 3.1(a) hereof by the number of days during the
  period from and including the date of the giving of notice under this
  paragraph to the date when sales under the registration statement may
  recommence.
 
    (b) Parent will, if requested, prior to filing such registration
  statement or any amendment or supplement thereto, furnish to the Large
  Shareholder requesting registration and each managing Underwriter, if any,
  copies thereof, and thereafter furnish to such Large Shareholder and each
  such Underwriter, if any, such number of copies of such registration
  statement, each amendment and supplement thereto (in each case including
  all exhibits thereto and documents incorporated by reference therein) and
  the prospectus included in such registration statement (including each
  preliminary prospectus) as such Large Shareholder or such Underwriter may
  reasonably request in order to facilitate the sale of the Registrable
  Securities.
 
    (c) After the filing of the registration statement, Parent will promptly
  notify such Large Shareholder of any stop order issued or, to the knowledge
  of Parent, threatened to be issued by the SEC and take all necessary
  actions required to prevent the entry of such stop order or to remove it if
  entered.
 
    (d) Parent will use its reasonable efforts to qualify the Registrable
  Securities for offer and sale under such other securities or blue sky laws
  of such jurisdictions in the United States as such Large Shareholder
  reasonably (in light of such Large Shareholder's intended plan of
  distribution) requests; provided that Parent will not be required to (i)
  qualify generally to do business in any jurisdiction where it would not
  otherwise be required to qualify but for this paragraph (d), (ii) subject
  itself to taxation in any such jurisdiction or (iii) consent to service of
  process in any such jurisdiction.
 
    (e) Parent shall, as promptly as reasonably practicable, notify each
  Large Shareholder that has sold, or is selling, Registrable Securities
  hereunder, at any time when a prospectus relating to the sale of the
  Registrable Securities is required by law to be delivered in connection
  with sales by an Underwriter or dealer, of the occurrence of an event
  requiring the preparation of a supplement or amendment to such prospectus
  so that, as thereafter delivered to the purchasers of such Registrable
  Securities, such prospectus will not contain an untrue statement of a
  material fact or omit to state any material fact required to be stated
  therein or necessary to make the statements therein, in the light of the
  circumstances under which they were made, not misleading, and as promptly
  as practicable make available to each such Large Shareholder and to the
  Underwriters any such supplement or amendment. Each Large Shareholder, by
  requesting a registration or selling Registrable Securities hereunder,
  shall be deemed to agree with Parent that, upon receipt of any notice from
  Parent of the happening of any event of the kind described in the preceding
  sentence, such Large Shareholder will forthwith discontinue the offer and
  sale of Registrable Securities pursuant to the registration statement
  covering such Registrable Securities until receipt of the copies of such
  supplemented or amended prospectus and, if so directed by Parent, such
  Large Shareholder will deliver to Parent all copies, other than permanent
  file copies then in Large Shareholder's possession, of the most recent
  prospectus covering such Registrable Securities at the time of receipt of
  such notice. In the event Parent shall give such notice, Parent shall
  extend the period during which any registration statement shall be
 
                                     A-51
<PAGE>
 
  maintained effective as provided in Section 3.1(a) hereof by the number of
  days during the period from and including the date of the giving of such
  notice to the date when Parent shall make available such supplemented or
  amended prospectus.
 
    (f) In the event of the issuance of a stop order suspending the
  effectiveness of a registration statement, or of any order suspending or
  preventing the use of any related prospectus or suspending the
  qualification of any Registrable Securities included in such registration
  statement for sale in any jurisdiction in the United States, Parent will
  promptly notify the holders of Registrable Securities and will use its
  commercially reasonable efforts to obtain the withdrawal of such order.
 
    (g) Parent will enter into customary agreements (including an
  underwriting agreement in customary form and satisfactory in form and
  substance to Parent in its reasonable judgment) and take such other actions
  as are reasonably required in order to expedite or facilitate the sale of
  such Registrable Securities.
 
    (h) Parent will furnish to each Large Shareholder that sells Registrable
  Securities hereunder and to each managing Underwriter, if any, a signed
  counterpart, addressed to such Large Shareholder and each Underwriter, of
  (i) an opinion or opinions of counsel to Parent and (ii) a comfort letter
  or comfort letters from Parent's independent auditors pursuant to SAS 72,
  each in customary form and covering such matters of the type customarily
  covered by opinions or comfort letters delivered to such parties.
 
    (i) Parent will make generally available to its securityholders, as soon
  as reasonably practicable, an earnings statement covering a period of 12
  months, beginning within three months after the effective date of the
  registration statement, which earnings statement shall satisfy the
  provisions of Section 11(a) of the Securities Act and the rules and
  regulations of the SEC thereunder.
 
    (j) Parent will use reasonable efforts to cause all such Registrable
  Securities to be listed on each securities exchange on which similar
  securities issued by Parent are then listed.
 
  3.2. Registration Expenses. In connection with any Demand Registration or
  Piggyback Registration by or for a Large Shareholder, Parent shall pay the
following expenses incurred in connection with such registration (the
"Registration Expenses"): (i) all filing fees with the SEC, (ii) fees and
expenses of compliance with securities or blue sky laws (including reasonable
fees and disbursements of counsel in connection with blue sky qualifications
of the Registrable Securities), (iii) printing expenses, (iv) the fees and
expenses incurred in connection with any listing of the Registrable
Securities, (v) fees and expenses of counsel and independent certified public
accountants for Parent (including the expenses of any comfort letters pursuant
to Section 3.1(g) hereof) and (vi) the reasonable fees and expenses of any
additional experts retained by Parent in connection with such registration.
Such Large Shareholder shall pay any underwriting fees, discounts or
commissions attributable to the sale of Registrable Securities, and any out-
of-pocket expenses of Large Shareholder, including such Large Shareholder's
counsel's fees and expenses. Parent shall pay internal Parent expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties).
 
  3.3. Participation in Underwritten Registrations. No person may participate
in any underwritten registered offering contemplated hereunder unless such
person (a) agrees to sell its securities on the basis provided in any
underwriting arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting arrangements and other documents
reasonably required under the terms of such underwriting arrangements and
these Registration Rights. Parent may require each Large Shareholder that
requests a registration or is selling Registrable Securities hereunder
promptly to furnish in writing to Parent such information regarding such Large
Shareholder, the plan of distribution of the Registrable Securities and other
information as Parent may from time to time reasonably request or as may be
legally required in connection with such registration.
 
IV.INDEMNIFICATION AND CONTRIBUTION
 
  4.1. Indemnification by Parent. Parent agrees to indemnify and hold harmless
each Large Shareholder, its officers and directors, and each person, if any,
who controls Large Shareholder within the meaning of either
 
                                     A-52
<PAGE>
 
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities caused by any
untrue statement or alleged untrue statement of a material fact contained in
any registration statement or prospectus relating to the Registrable
Securities (as amended or supplemented if Parent shall have furnished any
amendments or supplements thereto) or any preliminary prospectus, or caused by
any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages or liabilities are caused by
any such untrue statement or omission or alleged untrue statement or omission
based upon information furnished in writing to Parent by or on behalf of any
Large Shareholder or Underwriter for any Large Shareholder expressly for use
therein; provided that the foregoing indemnity agreement with respect to any
preliminary prospectus shall not inure to the benefit of any Large Shareholder
if a copy of the current prospectus was not provided to the purchaser of
Registrable Securities and such current prospectus would have cured the defect
giving rise to such loss, claim, damage or liability or for any sales
occurring after Parent has informed such Large Shareholder under Section
3.1(e) hereof and prior to the delivery by Parent of any supplement or
amendment to such prospectus. Parent also agrees to indemnify any Underwriters
of the Registrable Securities, their officers and directors and each person
who controls such underwriters on substantially the same basis as that of the
indemnification of such Large Shareholder provided in this Section 4.1.
 
  4.2. Indemnification by Large Shareholders. Each Large Shareholder, by
requesting any registration or making any sale of Registrable Securities
hereunder, shall be deemed to agree (on a several and not joint basis) to
indemnify and hold harmless Parent, its officers and directors, and each
person, if any, who controls Parent within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from Parent to Large Shareholder, but only with reference
to information furnished in writing by or on behalf of Large Shareholder
expressly for use in any registration statement or prospectus relating to such
Registrable Securities, or any amendment or supplement thereto, or any
preliminary prospectus. Each such Large Shareholder also shall be deemed to
agree to indemnify and hold harmless Underwriters of the Registrable
Securities, their officers and directors and each person who controls such
Underwriters on substantially the same basis as that of the indemnification of
Parent provided in this Section 4.2.
 
  4.3. Conduct of Indemnification Proceedings. In case any proceeding
(including any governmental investigation) shall be instituted involving any
person in respect of which indemnity may be sought pursuant to Section 4.1 or
4.2 hereof, such Person (the "Indemnified Party") shall promptly notify the
Person against whom such indemnity may be sought (the "Indemnifying Party") in
writing and the Indemnifying Party, upon the request of the Indemnified Party,
shall retain counsel reasonably satisfactory to such Indemnified Party to
represent such Indemnified Party and any others the Indemnifying Party may
designate in such proceeding and shall pay the fees and disbursements of such
counsel related to such proceeding. In any such proceeding, any Indemnified
Party shall have the right to retain its own counsel, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party
unless (i) the Indemnifying Party and the Indemnified Party shall have
mutually agreed to the retention of such counsel or (ii) the named parties to
any such proceeding (including any impleaded parties) include both the
Indemnified Party and the Indemnifying Party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the Indemnifying Party
shall not, in connection with any proceeding or related proceedings in the
same jurisdiction, be liable for the fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties, and that all such fees and expenses shall be
reimbursed as they are incurred. In the case of any such separate firm for the
Indemnified Parties, such firm shall be designated in writing by the
Indemnified Parties. The Indemnifying Party shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent, or if there be a final judgment for the plaintiff,
the Indemnifying Party shall indemnify and hold harmless such Indemnified
Parties from and against any loss or liability (to the extent stated above) by
reason of such settlement or judgment.
 
  4.4. Contribution. If the indemnification provided for in this Article IV is
unavailable to the Indemnified Parties in respect of any losses, claims,
damages or liabilities referred to herein, then each such Indemnifying Party,
in lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such
 
                                     A-53
<PAGE>
 
Indemnified Party as a result of such losses, claims, damages or liabilities
(i) in such proportion as is appropriate to reflect the relative benefits
received by Parent, any Large Shareholder and the Underwriters from the
offering of the securities, or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) but also
the relative fault of Parent, such Large Shareholder and the Underwriters in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by Parent, such Large
Shareholder and the Underwriters shall be deemed to be in the same proportion
as the total proceeds from the offering (net of underwriting discounts and
commissions but before deducting expenses) received by each of Parent and such
Large Shareholder and the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover page of the prospectus, bear to the aggregate public offering price of
the securities. The relative fault of Parent, a Large Shareholder and the
Underwriters shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
or on behalf of such party and the parties, relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or
omission.
 
  Parent and each Large Shareholder shall be deemed to agree that it would not
be just and equitable if contribution pursuant to this Section 4.4 were
determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an Indemnified
Party as a result of the losses, claims, damages or liabilities referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred
by such Indemnified Party in connection with investigating or defending any
such action or claim. Notwithstanding the provisions of this Section 4.4, no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission, and
Large Shareholder shall not be required to contribute any amount in excess of
the amount by which the net proceeds of the offering (before deducting
expenses) received by Large Shareholder exceeds the amount of any damages
which Large Shareholder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

Board of Directors
Xpedite Systems, Inc.
One Industrial Way West
Eatontown, New Jersey 07724
 
Members of the Board of Directors:
 
  Xpedite Systems, Inc. (the "Company") and Premiere Technologies, Inc. (the
"Acquiror"), and Nets Acquisition Corp., a newly formed, wholly owned
Subsidiary of the Acquiror (the "Acquisition Sub"), propose to enter into an
Agreement and Plan of Merger (the "Agreement"), pursuant to which Acquisition
Sub will be merged with and into the Company in a transaction (the "Merger")
in which each outstanding share of the Company's common stock, par value $.01
per share (the "Company Shares"), will be converted into the right to receive
a number (the "Exchange Ratio") of shares of the common stock of the Acquiror,
par value $.01 per share (the "Acquiror Shares"), calculated by dividing
$34.00 by the Average Closing Price (as defined in the Agreement) in
accordance with and subject to the limitations set forth in the Agreement (the
"Merger Consideration"). The Agreement provides that the Average Closing Price
will be deemed to equal (i) $27.20 in the event the actual Average Closing
Price is less than $27.20 and (ii) $39.20 in the event the actual Average
Closing Price is greater than $39.20, provided that if the actual Average
Closing Price is calculated to be less than $24.00, then the Company will have
the right to terminate the Agreement (the "Termination Right") unless the
Acquiror agrees to increase the Exchange Ratio such that the product of the
actual Average Closing Price multiplied by the Exchange Ratio will equal or
exceed $30.00. The Merger is conditioned upon, among other things, the
satisfaction of all conditions precedent to the closing of the Company's
acquisition (the "U.K. Acquisition") of Xpedite Systems Limited (the "U.K.
Company").
 
  You have asked us whether, in our opinion, the Merger Consideration is fair,
from a financial point of view, to the holders of Company Shares. We express
no opinion as to the relative value of the Merger Consideration as compared to
the consideration that may be proposed to be delivered pursuant to any other
transaction proposal which the Company has received or may receive. In
rendering our opinion we have evaluated the Company on a pro forma basis after
giving effect to the U.K. Acquisition. However, this opinion does not
constitute an opinion on the fairness or any other aspect of the U.K.
Acquisition itself. Furthermore, in rendering our opinion, due to the
speculative nature of the existing put-call arrangements relating to the U.K.
Company, Xpedite Systems GmbH and Xpedite Systems S.A. (the "European Put-Call
Arrangements"), we have evaluated the Company without regard to any aspect of
the European Put-Call Arrangements. This opinion is rendered as if the U.K.
Acquisition had been consummated and the European Put-Call Arrangements were
not contemplated or consummated and does not take into consideration the
potential financial ramifications to the Company of the European Put-Call
Arrangements, including any element of value associated therewith.
 
  In arriving at the opinion set forth below, we have, among other things:
 
  (1) reviewed certain publicly available business and financial information
      relating to the Company and the Acquiror which we deemed to be
      relevant;
 
                                      B-1
<PAGE>
 
   (2) reviewed certain information, including financial forecasts, relating
       to the business, earnings, cash flow, assets, liabilities and prospects
       of the Company (including after giving effect to the U.K. Acquisition)
       and the Acquiror (with respect to the Acquiror such financial forecast
       information was limited to fiscal years 1997 and 1998), furnished to us
       by the Company and the Acquiror, respectively;
 
   (3) reviewed certain information, including financial forecasts, relating
       to the business, earnings, cash flow, assets, liabilities and prospects
       of the U.K. Company, furnished to us by the Company and the U.K.
       Company;
 
   (4) conducted discussions with members of senior management and
       representatives of the Company and the Acquiror concerning the matters
       described in clauses 1 and 2 above as well as their respective business
       and prospects before and after giving effect to the Merger;
 
   (5) conducted discussions with members of senior management and
       representatives of the Company and the U.K. Company concerning the
       matters described in clause 3 above;
 
   (6) reviewed the market prices and valuation multiples for the Company
       Shares and the Acquiror Shares and compared them with those of certain
       publicly traded companies which we deemed to be relevant;
 
   (7) reviewed the results of operations of the Company (including after
       giving effect to the U.K. Acquisition) and the Acquiror and compared
       them with those of certain publicly traded companies which we deemed to
       be relevant;
 
   (8) compared the proposed financial terms of the Merger with the financial
       terms of certain other transactions which we deemed to be relevant;
 
   (9) participated in certain discussions and negotiations among
       representatives of the Company and the Acquiror and their financial and
       legal advisers;
 
  (10) reviewed the potential pro forma impact of the Merger;
 
  (11) reviewed a recent draft of the Agreement; and
 
  (12) reviewed such other financial studies and analyses and took into
       account such other matters as we deemed necessary, including our
       assessment of general economic, market and monetary conditions.
 
  In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all information supplied or otherwise made available to us,
discussed with or reviewed by or for us, or publicly available, and we have
not assumed any responsibility for independently verifying such information
and we have not undertaken an independent evaluation or appraisal of any of
the assets or liabilities of the Company (including after giving effect to the
U.K. Acquisition) or the Acquiror or been furnished with any such evaluation
or appraisal. In addition, we have not assumed any obligation to conduct any
physical inspection of the properties or facilities of the Company (including
after giving effect to the U.K. Acquisition) or the Acquiror. With respect to
the financial forecast information furnished to or discussed with us by the
Company, the U.K. Company or the Acquiror, we have assumed that they have been
reasonably prepared and reflect the best currently available
estimates and judgment of the Company's, the U.K. Company's or the Acquiror's
management as to the expected future financial performance of the Company
(including after giving effect to the U.K. Acquisition) or the Acquiror, as
the case may be. We have further assumed that the Merger will be accounted for
as a pooling of interests under generally accepted accounting principles and
that it will qualify as a tax-free reorganization for U.S. federal income tax
purposes. We have also assumed that the final form of the Agreement will be
substantially similar to the last draft reviewed by us.
 
  Our opinion is necessarily based upon market, economic and other conditions
as they exist and can be evaluated on, and on the information made available
to us as of, the date hereof. We have assumed that in the course of obtaining
the necessary regulatory or other consents or approvals (contractual or
otherwise) for the Merger, no restrictions, including any divestiture
requirements or amendments or modifications, will be imposed that will have a
material adverse effect on the contemplated benefits of the Merger. For
purposes of rendering this opinion, we have assumed that the Company will not
consummate the Merger under circumstances where the Termination Right is
exercisable.

  We are acting as financial advisor to the Company in connection with the
Merger and will receive a fee from the Company for our services, a significant
portion of which is contingent upon the consummation of the Merger. We are
also acting as financial advisor to the Company in connection with U.K.
Acquisition and will receive a fee from the Company for our services, a
significant portion of which is contingent upon the consummation of the U.K.
Acquisition. In addition, the Company has agreed to indemnify us for certain
liabilities arising out of our engagement. We may provide financial advisory
and financing services to the surviving corporation in the Merger and/or its
affiliates and may receive fees for the rendering of such services. In
addition, in the ordinary course of our business, we may actively trade the
Company Shares and other securities of the Company, as well as the Acquiror
Shares and other securities of the Acquiror, for our own account and for the
accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.
 
  This opinion is for the use and benefit of the Board of Directors of the
Company. Our opinion does not address the merits of the underlying decision by
the Company to engage in the Merger or any related transaction and does not
constitute a recommendation to any shareholder as to how such shareholder
should vote on the proposed Merger or any matter related thereto. We are not
expressing any opinion herein as to the prices at which the Company Shares or
the Acquiror Shares or any other securities of the Company or the Acquiror
will trade following the announcement or consummation of the Merger.
 
  On the basis of and subject to the foregoing, we are of the opinion that, as
of the date hereof, the Merger Consideration is fair, from a financial point
of view, to the holders of the Company Shares.
 
                                          Very truly yours,

                  [LETTERHEAD OF PRUDENTIAL SECURITIES INC.]
 
PRIVATE AND CONFIDENTIAL
 
                                                              November 12, 1997
 
The Board of Directors
Premiere Technologies, Inc.
3399 Peachtree Road
Atlanta, Georgia 30326
 
Members of the Board:
 
  We understand that Premiere Technologies, Inc., a Georgia corporation (the
"Company" or "Premiere"), Nets Acquisition Corp., a Delaware corporation and a
wholly-owned subsidiary of Premiere (the "Acquisition Sub"), and Xpedite
Systems, Inc., a Delaware corporation ("Xpedite"), propose to enter into an
Agreement and Plan of Merger (the "Agreement"). Pursuant to the Agreement, the
Acquisition Sub shall merge with and into Xpedite (the "Merger"). In the
Merger, each outstanding share of Common Stock, par value $.01 per share, of
Xpedite (the "Xpedite Common Stock") will be converted into the right to
receive a number of shares of Common Stock, par value $.01 per share, of the
Company (the "Premiere Common Stock") equal to the Exchange Ratio (as
hereinafter defined). The Merger is conditioned upon, among other matters, the
consummation of Xpedite's acquisition of Xpedite Systems Ltd. ("XSL"), a
United Kingdom affiliate of Xpedite, for approximately $87.0 million in cash.
The "Exchange Ratio" shall be determined based on the average closing price
(the "Average Closing Price") per share of Premiere Common Stock for the
twenty consecutive trading days as reported by NASDAQ/NMS ending at the close
of trading on the trading day immediately preceding the date of the special
meeting of Xpedite's stockholders in connection with the Merger (the
"Meeting"). The Exchange Ratio shall be determined in the following manner:
 
    (i)if the Average Closing Price is between $27.20 and $39.20, the
  Exchange Ratio shall be $34.00 divided by the Average Final Closing Price;
 
    (ii)if the Average Closing Price is below $27.20 then the Exchange Ratio
  shall be 1.250;
 
    (iii)if the Average Closing Price exceeds $39.20 then the Exchange Ratio
  shall be 0.867.
 
  The Agreement may be terminated by Xpedite at any time during the three
business day period commencing on the trading day immediately preceding the
date of the Meeting if the Average Closing Price is less than $24.00 (the
"Threshold Price"). The Company, however, may elect to increase the Exchange
Ratio to equal the quotient obtained by dividing the product of the Threshold
Price and the Exchange Ratio (as then in effect) by the Average Closing Price,
in which event, no termination shall have occurred and the Agreement shall
remain in effect.
 
  You have requested our opinion as to the fairness to the Company from a
financial point of view of the consideration to be paid by the Company in the
Merger.
 
  In conducting our analysis and arriving at the opinion expressed herein, we
have reviewed such materials and considered such financial and other factors
as we deemed relevant under the circumstances, including:
 
    (i)a draft dated November 12, 1997 of the Agreement;
 
    (ii)certain publicly-available information relating to Xpedite including,
  but not limited to, (a) Xpedite's Preliminary Proxy Statement dated
  September 18, 1997, (b) Xpedite's Registration Statement on Form S-4 as
  filed with the Securities and Exchange Commission on October 31, 1997, (c)
  Xpedite's Current Report on Form 8-K dated August 8, 1997, and (d)
  Xpedite's Schedule 13E-3 dated September 18, 1997 and Schedule 13E-3/A
  dated October 31, 1997;
 
    (iii)certain publicly-available historical financial and operating data
  for Xpedite including, but not limited to, (a) the Annual Report on Form
  10-K for the fiscal year ended December 31, 1996, (b) the Quarterly Report
  on Form 10-Q for the quarter ended June 30, 1997, and (c) Proxy Statements
  for the Meetings of Stockholders held on January 10, 1996, October 1, 1996,
  and May 15, 1997;
 
 
                                      C-1
<PAGE>
 
    (iv)certain publicly-available historical financial and operating data
  for the Company, including, but not limited to, (a) the Annual Report to
  Shareholders and Annual Report on Form 10-K for the fiscal year ended
  December 31, 1996, (b) the Quarterly Report on Form 10-Q for the quarter
  ended June 30, 1997, and (c) the Proxy Statement for the Annual Meeting of
  Shareholders held on April 30, 1997;
 
    (v)certain information relating to the Company, including projected
  income statement data for the fiscal year ending December 31, 1997 and
  December 31, 1998, prepared by the management of the Company;
 
    (vi)certain information relating to XSL, including historical financial
  data for the fiscal years ended December 31, 1993 through December 31,
  1996, and projected financial forecasts for the fiscal years ending
  December 31, 1997 through December 31, 2001, prepared by the management of
  Xpedite and XSL;
 
    (vii)certain information relating to Xpedite, including financial
  forecasts for the fiscal years ending December 31, 1997 through December
  31, 2001, prepared by the management of Xpedite;
 
    (viii)consolidated historical financial data for Xpedite and XSL for the
  fiscal years ending December 31, 1993 through December 31, 1996, and
  projected consolidated financial forecasts for the fiscal years ending
  December 31, 1997 through December 31, 2001 prepared by the management of
  Xpedite;
 
    (ix)publicly available financial, operating and stock market data
  concerning certain companies engaged in businesses we deemed comparable to
  Xpedite or otherwise relevant to our inquiry;
 
    (x)the financial terms of certain recent transactions we deemed relevant
  to our inquiry;
 
    (xi)the historical stock prices and trading volumes of Premiere Common
  Stock and Xpedite Common Stock; and
 
    (xii)such other financial studies, analyses and investigations that we
  deemed appropriate.
 
  We have assumed, with your consent, that the draft of the Agreement which we
reviewed (as referred to above) will conform in all material respects to that
document when in final form.
 
  We have met with the senior management of the Company, Xpedite and XSL to
discuss (i) the prospects for their respective businesses, (ii) their
estimates of such businesses' future financial performance, (iii) the
financial impact of the Merger on the respective companies and (iv) such other
matters that we deemed relevant.
 
  In connection with our review and analysis and in arriving at our opinion,
we have relied upon the accuracy and completeness of the financial and other
information provided to us by the Company, Xpedite and XSL and have not
undertaken any independent verification of such information or any independent
valuation or appraisal of any of the assets or liabilities of the Company,
Xpedite or XSL. With respect to certain financial forecasts provided to us by
the Company for the Company, and by Xpedite for Xpedite and XSL, we have
assumed that such information (and the assumptions and bases therefor)
represents each respective management's best currently available estimate as
to the future financial performance of the Company, Xpedite and XSL. Our
opinion is predicated on the Merger qualifying (i) as a reorganization within
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended, and (ii) for "pooling-of-interests" accounting treatment. Further,
our opinion is necessarily based on economic, financial and market conditions
as they exist and can only be evaluated as of the date hereof.
 
  Our opinion does not address nor should it be construed to address the
relative merits of the Merger or alternative business strategies that may be
available to the Company. In addition, this opinion does not in any manner
address the prices at which Premiere Common Stock will trade following
consummation of the Merger.
 
  As you know, we have been retained by the Company to render this opinion and
provide other financial advisory services in connection with the Merger and
will receive a fee for such services, the majority of which fee is contingent
upon the consummation of the Merger. In the ordinary course of business we may
actively trade the shares of Premiere Common Stock and Xpedite Common Stock
for our own account and for the accounts of customers and, accordingly, may at
any time hold a long or short position in such securities. As you are aware,
Prudential Securities Incorporated provides equity research coverage on
Xpedite and acted as lead-manager for the initial public offering of Xpedite's
Common Stock on February 14, 1994 and as co-manager for an offering of
Xpedite's Common Stock on August 15, 1996.

  This letter and the opinion expressed herein are for the use of the Board of
Directors of the Company. This opinion does not constitute a recommendation to
the shareholders of the Company as to how such shareholders should vote in
connection with the issuance of shares of Premiere Common Stock pursuant to
the Merger or as to any other action such shareholders should take regarding
the Merger. This opinion may not be reproduced, summarized, excerpted from or
otherwise publicly referred to or disclosed in any manner, without our prior
written consent; except that the Company may include this opinion in its
entirety in any proxy statement or information statement relating to the
Merger sent to the Company's shareholders.
 
  Based upon and subject to the foregoing, we are of the opinion that, as of
the date hereof, the consideration to be paid by the Company in the Merger is
fair to the Company from a financial point of view.
 
                                          Very truly yours,

 (and apart from rights accruing under special circumstances) having the right
 to vote at elections of directors (the "Base Capital Stock"); except that any

of the Company and its Subsidiaries, as well as key consultants and advisors
to the Company or any Subsidiary, an opportunity to acquire or increase their
proprietary interests in the Company. The objective of the Options and Awards

<PAGE>
 
Company and its Subsidiaries by providing the Grantees with an additional

service to the Company and its Subsidiaries.
 
  2.3 Effective Date. The effective date of this Plan is December 6, 1995, as

                                ADMINISTRATION
 
  4.1 Duties and Powers of the Committee. This Plan shall be administered by
the Committee. The Committee shall select one of its members as its Chairman
and shall hold its meetings at such times and places as it may determine. The
Committee shall keep minutes of its meetings and shall make such rules and
regulations for the conduct of its business as it may deem necessary. The
Committee shall have the power to act by unanimous written consent in lieu of
a meeting, and to meet telephonically. In administering this Plan, the
Committee's actions and determinations shall be binding on all interested
parties. The Committee shall have the power to grant Options or Awards in
accordance with the provisions of this Plan and may grant Options and Awards
singly, in combination, or in tandem. Subject to the provisions of this Plan,
the Committee shall have the discretion and authority to determine those
persons to whom Options or Awards will be granted and whether such Options
will be accompanied by the right to receive Reload Options, the number of
shares of Stock subject to each Option or Award, such other matters as are
specified herein, and any other terms and conditions of a Stock Option
Agreement, Restriction Agreement and an SAR Agreement. The Committee shall
also have the discretion and authority to delegate to any Officer its powers
to grant Options or Awards under this Plan to any person who is an employee of
the Company or any Subsidiary but not an Officer or Director. To the extent
not inconsistent with the provisions of this Plan, the Committee may give a
Grantee an election to surrender an Option or Award in exchange for the grant
of a new Option or Award, and shall have the authority to amend or modify an
outstanding Stock Option Agreement, Restriction Agreement or SAR Agreement, or
to waive any provision thereof, provided that the Grantee consents to such
action.
 
  4.2 Interpretation; Rules. Subject to the express provisions of this Plan,
the Committee shall have complete authority to interpret this Plan, to
prescribe, amend and rescind rules and regulations relating to it, to
determine the details and provisions of each Stock Option Agreement,
Restriction Agreement and SAR Agreement, and to make all other determinations
necessary or advisable for the administration of this Plan, including, without
limitation, the amending or altering of this Plan and any Options or Awards
granted hereunder as may be required to comply with or to conform to any
federal, state or local laws or regulations.
 
  4.3 No Liability. Neither any Director nor any member of the Committee shall
be liable to any person or entity for any act or determination made in good
faith with respect to this Plan or any Option or Award granted hereunder.
 
  4.4 Majority Rule. A majority of the members of the Committee shall
constitute a quorum, and any action taken by a majority at a meeting at which
a quorum is present, or any action taken without a meeting evidenced by a
writing executed by all the members of the Committee, shall constitute the
action of the Committee.

  4.5 Company Assistance. The Company shall supply full and timely information
to the Committee on all matters relating to eligible persons, their

                                   ARTICLE V
                        SHARES OF STOCK SUBJECT TO PLAN
 
  5.1 Limitations. Subject to any antidilution adjustment pursuant to the
provisions of Section 5.2, the maximum number of shares of Stock that may be
issued hereunder shall be 4,000,000; provided, that the stock dividend
declared shortly prior to the Company's initial public offering did not and
shall not affect the maximum number of shares of Stock that may be issued
hereunder. Any or all shares of Stock subject to the Plan may be issued in any
combination of Incentive Stock Options, non-Incentive Stock Options,
Restricted Stock and SARs, and the amount of Stock subject to the Plan may be
increased from time to time in accordance with Article X hereof.
Notwithstanding any provision in the Plan to the contrary, the maximum number
of shares of Stock with respect to one or more Options and/or SARs that may be
granted during any one calendar year under the Plan to any one Covered
Employee shall be 500,000. The maximum fair market value of any Restricted
Stock Awards that may be received by a Covered Employee (less any
consideration paid by the participant for such Award) during any one calendar
year under the Plan shall be $2,000,000.
 
  Shares subject to an Option or issued as an Award may be either authorized
and unissued shares or shares issued and later acquired by the Company. The
shares covered by any unexercised portion of an Option that has terminated for
any reason (except as set forth in the following paragraph), or any forfeited
portion of an Award, may again be optioned or Awarded under this Plan, and
such shares shall not be considered as having been optioned or issued in
computing the number of shares of Stock remaining available for Options or
Awards hereunder.
 
  If Options are issued in respect of options to acquire stock of any entity
acquired, by merger or otherwise, by the Company or any Subsidiary, to the
extent that such issuance shall not be inconsistent with the terms,
limitations and conditions of Code Section 422 or Rule 16b-3 under the
Exchange Act, the aggregate number of shares of Stock for which Options may be
granted hereunder shall automatically be increased by the number of shares
subject to the Options so issued; provided, however, that the aggregate number
of shares of Stock for which Options may be granted hereunder shall
automatically be decreased by the number of shares covered by any unexercised
portion of an Option so issued that has terminated for any reason, and the
shares subject to any such unexercised portion may not be optioned to any
other person.
 
  5.2 Antidilution.
 
    (a) If (i) the Outstanding shares of Stock are increased, decreased, or
  changed into or exchanged for a different number or kind of shares or other
  securities of the Company, by reason of merger, consolidation,
  reorganization, recapitalization, reclassification, combination or exchange
  of shares, or stock split or stock dividend (excluding the Stock dividend
  referred to in Section 5.1), (ii) any spin-off, split-off or other
  distribution of assets materially affects the price of the Company's stock,
  or (iii) there is any assumption and conversion to this Plan by the Company
  of an acquired company's outstanding option grants, then:
 
      (A) the aggregate number and kind of shares of Stock for which
    Options or Awards may be granted hereunder shall be adjusted
    appropriately by the Committee, and
 
      (B) the rights of Optionees (concerning the number of shares subject
    to Options and the Exercise Price) under outstanding Options and the
    rights of the holders of Awards (concerning the terms and conditions of
    the lapse of any then remaining restrictions), shall be adjusted
    appropriately by the Committee.
 
    (b) If the Company is a party to any reorganization in which it does not
  survive, involving merger, consolidation, or acquisition of the stock or
  substantially all the assets of the Company, the Committee, in its
  discretion, may:
 
                                      D-5
<PAGE>
 
      (i) notwithstanding other provisions hereof, declare that all Options
    granted under this Plan shall become exercisable immediately
    notwithstanding the provisions of the respective Stock Option
    Agreements regarding exercisability, that all such Options shall
    terminate thirty (30) days after the Committee gives written notice of
    the immediate right to exercise all such Options and of the decision to
    terminate all Options not exercised within such 30-day period, and that
    all then-remaining restrictions pertaining to Awards under this Plan
    shall immediately lapse; and/or
 
      (ii) notify all Grantees that all Options and Awards granted under
    this Plan shall be assumed by the successor corporation or substituted
    on an equitable basis with options or restricted stock issued by such
    successor corporation.
 
    (c) If the Company is to be liquidated or dissolved in connection with a
  reorganization described in Section 5.2(b), the provisions of that Section
  shall apply. In all other instances, the adoption of a plan of dissolution
  or liquidation of the Company shall, notwithstanding other provisions
  hereof, cause all then-remaining restrictions pertaining to Options and
  Awards under the Plan to lapse, and shall cause every Option outstanding
  under the Plan to terminate to the extent not exercised prior to the
  adoption of the plan of dissolution or liquidation by the shareholders;
  provided that, notwithstanding any other provisions hereof, the Committee
  may declare all Options granted under the Plan to be exercisable at any
  time on or before the fifth (5th) business day following such adoption,
  notwithstanding the provisions of the respective Stock Option Agreements
  regarding exercisability.
 
    (d) The adjustments described in paragraphs (a) through (c) of this
  Section 5.2, and the manner of their application, shall be determined
  solely by the Committee, and any such adjustment may provide for the
  elimination-of fractional share interests; provided, however, that any
  adjustment made by the Committee shall be made in a manner that will not
  cause an Incentive Stock Option to be other than an Incentive Stock Option
  under applicable statutory and regulatory provisions. The adjustments
  required under this Article V shall apply to any successors of the Company
  and shall be made regardless of the number or type of successive events
  requiring such adjustments.
 
                                  ARTICLE VI
                                    OPTIONS
 
  6.1 Types of Options Granted. The Committee may, under this Plan, grant
either Incentive Stock Options or Options which do not qualify as Incentive
Stock Options. Within the limitations provided in this Plan, both types of
Options may be granted to the same person at the same time, or at different
times, under different terms and conditions, as long as the terms and
conditions of each Option are consistent with the provisions of this Plan.
Without limitation of the foregoing, Options may be granted subject to
conditions based on the satisfaction of performance goals or any other factor
the Committee deems relevant.
 
  6.2 Option Grant and Agreement. Each Option granted hereunder shall be
evidenced by minutes of a meeting or the written consent of the Committee and
by a written Stock Option Agreement executed by the Company and the Optionee.
The terms of the Option, including the Option's duration, time or times of
exercise, exercise price, whether the Option is intended to be an Incentive
Stock Option, and whether the Option is to be accompanied by the right to
receive a Reload Option, shall be stated in the Stock Option Agreement. No
Incentive Stock Option may be granted more than ten (10) years after the
effective date of this Plan. Separate Stock Option Agreements may be used for
Options intended to be Incentive Stock Options and those not so intended, but
any failure to use such separate agreements shall not invalidate, or otherwise
adversely affect the Optionee's interest in, the Options evidenced thereby.
 
  6.3 Optionee Limitations. The Committee shall not grant an Incentive Stock
Option to any person who, at the time the Incentive Stock Option is granted:
 
    (a) is not an employee of the Company or any of its Subsidiaries; or
 
                                      D-6
<PAGE>
 
    (b) owns or is considered to own stock possessing at least ten percent
  (10%) of the total combined voting power of all classes of stock of the
  Company or any of its Subsidiaries; provided, however, that this limitation
  shall not apply if at the time an Incentive Stock Option is granted the
  Exercise Price is at least one hundred ten percent (110%) of the Fair
  Market Value of the Stock subject to such Option and such Option by its
  terms is not exercisable after five (5) years from the date on which the
  Option is granted. For the purpose of this subsection (b), a person shall
  be considered to own: (i) the stock owned, directly or indirectly, by or
  for his or her brothers and sisters (whether by whole or half blood),
  spouse, ancestors and lineal descendants; (ii) the stock owned, directly or
  indirectly, by or for a corporation, partnership, estate or trust in
  proportion to such person's stock interest, partnership interest or
  beneficial interest therein; and (iii) the stock which such person may
  purchase under any outstanding options of the Company or any Subsidiary.
 
  6.4 $100,000 Limitation. Except as provided below, the Committee shall not
grant an Incentive Stock Option to, or modify the exercise provisions of any
outstanding Incentive Stock Option held by, any person who, at the time the
Incentive Stock Option is granted (or modified), would thereby receive or hold
any Incentive Stock Options of the Company and any Subsidiary, such that the
aggregate Fair Market Value (determined as of the respective dates of grant or
modification of each Option) of the Stock with respect to which such Incentive
Stock Options are exercisable for the first time during any calendar year is
in excess of $100,000 (or such other limit as may be prescribed by the Code
from time to time); provided, that the foregoing restriction on modification
of outstanding Incentive Stock Options shall not preclude the Committee from
modifying an outstanding Incentive Stock Option if, as a result of such
modification and with the consent of the Optionee, such Option no longer
constitutes an Incentive Stock Option; and provided further that, if the
$100,000 limitation (or such other limitation prescribed by the Code)
described in this Section 6.4 is exceeded, the Incentive Stock Option, the
granting or modification of which resulted in the exceeding of such limit,
shall be treated as an Incentive Stock Option up to the limitation and the
excess shall be treated as an Option not qualifying as an Incentive Stock
Option.
 
  6.5 Exercise Price. The Exercise Price of the Stock subject to each Option
shall be determined by the Committee. Subject to the provisions of Section
6.3(b) hereof, the Exercise Price of an Incentive Stock Option shall not be
less than the Fair Market Value of the Stock as of the date the Option is
granted (or in the case of an Incentive Stock Option that is subsequently
modified, on the date of such modification).
 
  6.6 Exercise Period. The period for the exercise of each Option granted
hereunder shall be determined by the Committee, but the Stock Option Agreement
with respect to each Option intended to be an Incentive Stock Option shall
provide that such Option shall not be exercisable after the expiration of ten
(10) years from the date of grant (or modification) of the Option.
 
  6.7 Option Exercise.
 
    (a) Unless otherwise provided in the Stock Option Agreement or Section
  6.6 hereof, an Option may be exercised at any time or from time to time
  during the term of the Option as to any or all full shares which have
  become Purchasable under the provisions of the Option, but not at any time
  as to less than one hundred (100) shares unless the remaining shares that
  have become so Purchasable are less than one hundred (100) shares. The
  Committee shall have the authority to prescribe in any Stock Option
  Agreement that the Option may be exercised only in accordance with a
  vesting schedule during the term of the Option.
 
    (b) An Option shall be exercised by (i) delivery to the Company at its
  principal office a written notice of exercise with respect to a specified
  number of shares of Stock and (ii) payment to the Company at that office of
  the full amount of the Exercise Price for such number of shares in
  accordance with Section 6.7(c). If requested by an Optionee, an Option may
  be exercised with the involvement of a stockbroker in accordance with the
  federal margin rules set forth in Regulation T (in which case the
  certificates representing the underlying shares will be delivered by the
  Company directly to the stockbroker).
 
                                      D-7
<PAGE>
 
    (c) The Exercise Price is to be paid in full in cash upon the exercise of
  the Option and the Company shall not be required to deliver certificates
  for the shares purchased until such payment has been made; provided,
  however, the Committee may provide in a Stock Option Agreement (or may
  otherwise determine in Its sole discretion at the time of exercise) that in
  lieu of cash, all or any portion of the Exercise Price may be paid by
  tendering to the Company shares of Stock duly endorsed for transfer and
  owned by the Optionee, or by authorization to the Company to withhold
  shares of Stock otherwise issuable upon exercise of the Option, in each
  case to be credited against the Exercise Price at the Fair Market Value of
  such shares on the date of exercise (however, no fractional shares may be
  so transferred, and the Company shall not be obligated to make any cash
  payments in consideration of any excess of the aggregate Fair Market Value
  of shares transferred over the aggregate Exercise Price); provided further,
  the Committee may provide in a Stock Option Agreement (or may otherwise
  determine in its sole discretion at the time of exercise) that, in lieu of
  cash or shares, all or a portion of the Exercise Price may be paid by the
  Optionee's execution of a recourse note equal to the Exercise Price or
  relevant portion thereof, subject to compliance with applicable state and
  federal laws, rules and regulations.
 
    (d) In addition to and at the time of payment of the Exercise Price, the
  Company may withhold, or require the Optionee to pay to the Company in
  cash, the amount of any federal, state and local income, employment or
  other withholding taxes which the Committee determines are required to be
  withheld under federal, state or local law in connection with the exercise
  of an Option; provided, however, the Committee may provide in a Stock
  Option Agreement (or may otherwise determine in its sole discretion at the
  time of exercise) that all or any portion of such tax obligations may, upon
  the election of the Optionee, be paid by tendering to the Company whole
  shares of Stock duly endorsed for transfer and owned by the Optionee, or by
  authorization to the Company to withhold shares of Stock otherwise issuable
  upon exercise of the Option, in either case in that number of shares having
  a Fair Market Value on the date of exercise equal to the amount of such
  taxes thereby being paid.
 
    (e) The holder of an Option shall not have any of the rights of a
  shareholder with respect to the shares of Stock subject to the Option until
  such shares have been issued and transferred to the Optionee upon the
  exercise of the Option.
 
  6.8 Reload Options.
 
    (a) The Committee may specify in a Stock Option Agreement (or may
  otherwise determine in its sole discretion) that a Reload Option shall be
  granted, without further action of the Committee, (i) to an Optionee who
  exercises an Option (including a Reload Option) by surrendering shares of
  Stock in payment of amounts specified in Sections 6.7(c) or 6.7(d) hereof,
  (ii) for the same number of shares as are surrendered to pay such amounts,
  (iii) as of the date of such payment and at an Exercise Price equal to the
  Fair Market Value of the Stock on such date, and (iv) otherwise on the same
  terms and conditions as the Option whose exercise has occasioned such
  payment, except as provided below and subject to such other contingencies,
  conditions, or other terms as the Committee shall specify at the time such
  exercised Option is granted.
 
    (b) Unless provided otherwise in the Stock Option Agreement, a Reload
  Option may not be exercised by an Optionee (i) prior to the end of a one
  (1) year period from the date that the Reload Option is granted, and (ii)
  unless the Optionee retains beneficial ownership of the shares of Stock
  issued to such Optionee upon exercise of the Option referred to above in
  Section 6.8(a)(i), for a period of one (1) year from the date of such
  exercise.
 
  6.9 Nontransferability. No Option shall be transferable by an Optionee other
than by will or the laws of descent and distribution or, in the case of non-
Incentive Stock Options, pursuant to a Qualified Domestic Relations Order.
During the lifetime of an Optionee, Options shall be exercisable only by such
Optionee (or by such Optionee's guardian or legal representative, should one
be appointed).
 
  6.10 Termination of Employment or Service. The Committee shall have the
power to specify, with respect to the Options granted to a particular
Optionee, the effect upon such Optionee's right to exercise an Option upon
termination of such Optionee's employment or service under various
circumstances, which effect
 
                                      D-8
<PAGE>
 
may include immediate or deferred termination of such Optionee's rights under
an Option, or acceleration of the date at which an Option may be exercised in
full; provided, however, that in no event may an Incentive Stock Option be
exercised after the expiration of ten (10) years from the date of grant
thereof.
 
  6.11 Employment Rights. Nothing in this Plan or in any Stock Option
Agreement shall confer on any person any right to continue in the employ of
the Company or any of its Subsidiaries, or shall interfere in any way with the
right of the Company or any of its Subsidiaries to terminate such person's
employment at any time.
 
  6.12 Certain Successor Options. To the extent not inconsistent with the
terms, limitations and conditions of Code Section 422 and any regulations
promulgated thereunder, an Option issued in respect of an option held by an
employee to acquire stock of any entity acquired, by merger or otherwise, by
the Company or any Subsidiary, may contain terms that differ from those stated
in this Article VI, but solely to the extent necessary to preserve for any
such employee the rights and benefits contained in such predecessor option, or
to satisfy the requirements of Code Section 424(a).
 
  6.13 Effect of Change in Control. The Committee may determine, at the time
of granting an Option or thereafter, that such Option shall become exercisable
on an accelerated basis in the event that a Change in Control occurs with
respect to the Company (and the Committee shall have the discretion to modify
the definition of Change in Control in a particular Option Agreement). If the
Committee finds that there is a reasonable possibility that, within the
succeeding six (6) months, a Change in Control will occur with respect to the
Company, then the Committee may determine that all outstanding Options shall
be exercisable on an accelerated basis.
 
                                  ARTICLE VII
                               RESTRICTED STOCK
 
  7.1 Awards of Restricted Stock. The Committee may grant Awards of Restricted
Stock, which shall be governed by a Restriction Agreement between the Company
and the Grantee. Each Restriction Agreement shall contain such restrictions,
terms and conditions (including, without limitation, the satisfaction of
stated performance goals) as the Committee may, in its discretion, determine,
and may require that an appropriate legend be placed on the certificates
evidencing the subject Restricted Stock. Shares of Restricted Stock granted
pursuant to an Award hereunder shall be issued in the name of the Grantee as
soon as reasonably practicable after the Award is granted, provided that the
Grantee has executed the Restriction Agreement governing the Award, the
appropriate blank stock powers and, in the discretion of the Committee, an
escrow agreement and any other documents which the Committee may require as a
condition to the issuance of such Shares. If a Grantee shall fail to execute
the foregoing documents within the time period prescribed by the Committee, if
any, the Award shall be void. At the discretion of the Committee, Shares
issued in connection with an Award shall be deposited together with the stock
powers with an escrow agent designated by the Committee. Unless the Committee
determines otherwise and as set forth in the Restriction Agreement, upon
delivery of the Shares to the escrow agent, the Grantee shall have all of the
rights of a shareholder with respect to such Shares, including the right to
vote the Shares and to receive all dividends or other distributions paid or
made with respect to the Shares.
 
  7.2 Nontransferability. Until any restrictions upon Restricted Stock awarded
to a Grantee shall have lapsed in a manner set forth in Section 7.3, such
shares of Restricted Stock shall not be transferable other than by will or the
laws of descent and distribution, or pursuant to a Qualified Domestic
Relations Order, nor shall they be delivered to the Grantee.
 
  7.3 Lapse of Restrictions. Restrictions upon Restricted Stock awarded
hereunder shall lapse at such time or times and on such terms and conditions
as the Committee may, in its discretion, determine at the time the Award is
granted or thereafter.
 
  7.4 Termination of Employment. The Committee shall have the power to
specify, with respect to each Award granted to any particular Grantee, the
effect upon such Grantee's rights with respect to such Restricted Stock of the
termination of such Grantee's employment under various circumstances, which
effect may include

<PAGE>
 
immediate or deferred forfeiture of such Restricted Stock or acceleration of
the date on which any then remaining restrictions shall lapse.
 
  7.5 Treatment of Dividends. At the time an Award of Restricted Stock is made
the Committee may, in its discretion, determine that the payment to the
Grantee of any dividends, or a specified portion thereof, declared or paid on
such Restricted Stock shall be (a) deferred until the lapsing of the relevant
restrictions and (b) held by the Company for the account of the Grantee until
such lapsing. In the event of such deferral, there shall be credited at the
end of each year (or portion thereof) interest on the amount of the account
outstanding during such year at a rate per annum determined by the Committee.
Payment of deferred dividends, together with interest thereon, shall be made
upon the lapsing of restrictions imposed on such Restricted Stock, and any
dividends deferred (together with any interest thereon) in respect of
Restricted Stock shall be forfeited upon any forfeiture of such Restricted
Stock.
 
  7.6 Delivery of Shares. Except as provided otherwise in Article IX below,
within a reasonable period of time following the lapse of the restrictions on
shares of Restricted Stock, the Committee shall cause a stock certificate to
be delivered to the Grantee with respect to such shares and such shares shall
be free of all restrictions hereunder.
 
                                 ARTICLE VIII
                           STOCK APPRECIATION RIGHTS
 
  8.1 SAR Awards. The Committee may grant Awards of SARs, which shall be
governed by an SAR Agreement between the Company and the Grantee. Each SAR
Agreement shall contain such restrictions, terms and conditions (including,
without limitation, the satisfaction of stated performance goals) as the
Committee may, in its discretion, determine.
 
  8.2 Determination of Price. The SAR Price shall be established by the
Committee in its sole discretion. The SAR Price shall not be less than one
hundred percent (100%) of the Fair Market Value of the Stock on the date the
SAR is granted for an SAR issued in tandem with an Incentive Stock Option.
 
  8.3 Exercise of an SAR. Upon exercise of an SAR, the Grantee shall be
entitled, subject to the terms and conditions of this Plan and the SAR
Agreement, to receive for each share of Stock being exercised under the SAR,
the excess of (a) the Fair Market Value of such share of Stock on the date of
exercise over (b) the SAR Price for such share of Stock.
 
  8.4 Payment for an SAR. At the sole discretion of the Committee, the payment
of such excess shall be made in (a) cash, (b) shares of Stock, or (c) a
combination of both. Shares of Stock used for this payment shall be valued at
their Fair Market Value on the date of exercise of the applicable SAR.
 
  8.5 Status of SAR Shares. Shares of Stock subject to an Award of an SAR
shall be considered shares of Stock which may be issued under this Plan for
purposes of Section 5.1 hereof, unless the SAR Agreement making the Award of
the SAR provides that the exercise of such SAR results in the termination of
an unexercised Option for the same number of shares of Stock.
 
  8.6 Termination of SARs. An SAR may be terminated as follows:
 
    (a) During the period of a Grantee's continuous employment with the
  Company or a Subsidiary, an SAR will be terminated only if it has been
  fully exercised or it has expired by its terms.
 
    (b) Upon termination of a Grantee's employment with the Company or a
  Subsidiary, the SAR will terminate upon the earliest of (1) the full
  exercise of the SAR, (ii) the expiration of the SAR by its terms, and (iii)
  not more than three (3) months following the date of employment
  termination; provided, however, should termination of employment (A) result
  from the death or Permanent and Total Disability of the
 
                                     D-10
<PAGE>
 
  Grantee, the period referenced in clause (iii) hereof shall be one (1)
  year, or (B) be for Cause, the SAR will terminate on the date of employment
  termination. For purposes of this Plan, a leave of absence approved by the
  Company shall not be deemed to be termination of employment unless
  otherwise provided in the SAR Agreement or by the Company on the date of
  the leave of absence.
 
    (c) Subject to the terms of the SAR Agreement with the Grantee, if a
  Grantee should die or become Subject to a Permanent and Total Disability
  prior to the termination of employment with the Company or any Subsidiary
  and prior to the termination of an SAR, such SAR may be exercised to the
  extent that the Grantee shall have been entitled to exercise it at the time
  of death or Permanent and Total Disability, as the case may be, by the
  Grantee, the estate of the Grantee or the person or persons to whom the SAR
  shall have been transferred by will or by the laws of descent and
  distribution.
 
    (d) Except as otherwise expressly provided in the SAR Agreement with the
  Grantee, in no event will the continuation of the term of an SAR beyond the
  date of termination of employment allow the Employee, or his beneficiaries
  or heirs, to accrue additional rights under this Plan, have additional SARs
  available for exercise, or receive a higher benefit than the benefit
  payable as if the SAR had been exercised on the date of employment
  termination.
 
  8.7 No Shareholder Rights. The Grantee of an SAR shall have no rights as a
shareholder with respect to such SAR. In addition, no adjustment shall be made
for dividends (ordinary or extraordinary, whether in cash, securities or other
property) or distributions or rights except as provided in Section 5.2 hereof.
 
                                  ARTICLE IX
                              STOCK CERTIFICATES
 
  The Company shall not be required to issue or deliver any certificate for
shares of Stock purchased upon the exercise of any Option granted hereunder or
any portion thereof, or deliver any certificate for shares of Restricted Stock
granted hereunder, prior to fulfillment of all of the following conditions:
 
    (a) the admission of such shares to listing on all stock exchanges on
  which the Stock is then listed;
 
    (b) the completion of any registration or other qualification of such
  shares which the Committee shall deem necessary or advisable under any
  federal or state law or under the rulings or regulations of the Securities
  and Exchange Commission or any other governmental regulatory body;
 
    (c) the obtaining of any approval or other clearance from any federal or
  state governmental agency or body which the Committee shall determine to be
  necessary or advisable; and
 
    (d) the lapse of such reasonable period of time following the exercise of
  the Option as the Board from time to time may establish for reasons of
  administrative convenience.
 
  Stock certificates issued and delivered to Grantees shall bear such
restrictive legends as the Company shall deem necessary or advisable pursuant
to applicable federal and state securities laws.
 
                                   ARTICLE X
                           TERMINATION AND AMENDMENT
 
  10.1 Termination and Amendment. The Board at any time may amend or terminate
the Plan without shareholder approval; provided, however, that the Board may
condition any amendment on the approval of shareholders of the Company if such
approval is necessary or advisable with respect to tax, securities or other
applicable laws.
 
  10.2 Effect on Grantee's Rights. No termination, amendment or modification
of this Plan shall adversely affect a Grantee's rights under a Stock Option
Agreement, Restriction Agreement or an SAR Agreement without the consent of
the Grantee or his legal representative.

                                  ARTICLE XI
                   RELATIONSHIP TO OTHER COMPENSATION PLANS
 
  The adoption of this Plan shall not affect any other stock option, incentive
or other compensation plans in effect for the Company or any of its
Subsidiaries; nor shall the adoption of the Plan preclude the Company or any
of its Subsidiaries from establishing any other form of incentive or other
compensation plan for employees or Directors of the Company or any of its
Subsidiaries.
 
                                  ARTICLE XII
                                 MISCELLANEOUS
 
  12.1. Performance Goals. The Committee may determine that any Award granted
pursuant to this Plan to a participant (including, but not limited to,
participants who are Covered Employees) shall be determined solely on the
basis of (a) the achievement by the Company or a Subsidiary of a specified
target return on equity or assets, (b) the Company's or Subsidiary's stock
price, (c) the achievement by the Company or a business unit of the Company or
Subsidiary of a specified target net income or earnings per share, including
without limitation earnings before income and taxes, or (d) any combination of
the goals set forth in (a) through (c) above. Furthermore, the Committee
reserves the right for any reason to reduce (but not increase) any Award,
notwithstanding the achievement of a specified goal. If an Award is made on
such basis, the Committee shall establish goals prior to the beginning of the
period for which such performance goal relates (or such later date as may be
permitted under Code Section 162(m)). Any payment of an Award granted with
performance goals shall be conditioned on the written certification of the
Committee in each case that the performance goals and any other material
conditions were satisfied.
 
  12.2 Replacement or Amended Grants. At the sole discretion of the Committee,
and subject to the terms of this Plan, the Committee may modify outstanding
Options or Awards or accept the surrender of outstanding Options or Awards and
grant new Options or Awards in substitution thereof. However, no modification
of an Option or Award shall adversely affect a Grantee's rights under a Stock
Option Agreement, Restriction Agreement or an SAR Agreement without the
consent of the Grantee or his legal representative.
 
  12.3 Forfeiture for Competition. If a Grantee provides services to a
competitor of the Company or any of its Subsidiaries, whether as an employee,
officer, director, independent contractor, consultant, agent or otherwise,
which services are of a nature that can reasonably be expected to involve the
skills and experience used or developed by the Grantee while an employee,
consultant or advisor of the Company or any Subsidiary, then that Grantee's
rights under any Options outstanding hereunder shall be forfeited and
terminated, and any shares of Restricted Stock held by such Grantee subject to
remaining restrictions shall be forfeited, subject in each case to a
determination to the contrary by the Committee.
 
  12.4 Plan Binding on Successors. This Plan shall be binding upon the
successors and assigns of the Company.
 
  12.5 Singular, Plural, Gender. Whenever used herein, nouns in the singular
shall include the plural, and the masculine pronoun shall include the feminine
gender and vice versa.
 
  12.6 Headings Not Part of Plan. Headings of Articles and Sections hereof are
inserted for convenience and reference, and they do not constitute part of
this Plan.
 
  12.7 Interpretation. With respect to Section 16 Insiders, transactions under
this Plan are intended to comply with all applicable conditions of Rule 16b-3
or its successors under the Exchange Act, and shall be interpreted consistent
therewith.

                                    PART II
 
                  INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
 
  The Georgia Business Corporation Code permits a corporation to eliminate or
limit the personal liability of a director to the corporation or its
shareholders for monetary damages for breach of duty of care or other duty as
a director, provided that no provision shall eliminate or limit the liability
of a director: (i) for an appropriation, in violation of his duties, of any
business opportunity of the corporation; (ii) for acts or omissions which
involve intentional misconduct or a knowing violation of law; (iii) for
unlawful corporate distributions; or (iv) for any transaction from which the
director received an improper personal benefit. This provision relates only to
breaches of duty by directors in their capacity as directors (and not in any
other corporate capacity, such as officers) and limits liability only for
breaches of fiduciary duties under Georgia corporate law (and not for
violation of other laws, such as the federal securities laws). The
Registrant's Articles of Incorporation, as amended, exonerate the Registrant's
directors from monetary liability to the extent described above. In addition
to such rights as may be provided by law, the Registrant's Bylaws provide
broad indemnification rights to the Registrant's directors and such officers,
employees and agents as may be selected by such directors, with respect to
various civil and criminal liabilities and losses which may be incurred by
such director, officer, agent or employee pursuant to any pending or
threatened litigation or other proceedings, except that such indemnification
does not apply in the same situations described above with respect to the
exculpation from liability of the Registrant's directors. The Registrant is
also obligated to reimburse such directors and other parties for expenses,
including legal fees, court costs and expert witness fees, incurred by such
person in defending against any such liabilities and losses, as long as such
person in good faith believes that he or she acted in accordance with the
applicable standard of conduct with respect to the underlying accusations
giving rise to such liabilities or losses and agrees to repay to the
Registrant any advances made under the Bylaws. Any amendment or other
modification to the Bylaws which limits or otherwise adversely affects the
rights to indemnification currently provided therein shall apply only to
proceedings based upon actions and events occurring after such amendment and
delivery of notice thereof to the indemnified parties. Such amendments can
only made upon the affirmative vote of (i) the holders of at least 75% of the
shares entitled to vote to alter, amend or repeal the provisions of the Bylaws
or (ii) a majority of the Board of Directors present at the meeting at which
the votes is are taken.
 
  The Registrant has entered into separate indemnification agreements with
each of its directors and certain of its officers and employees, whereby the
Registrant agreed, among other things, to provide for indemnification and
advancement of expenses in a manner and subject to terms and conditions
similar to those set forth in the Bylaws. These agreements may not be
abrogated by action of the shareholders. In addition, the Registrant holds an
insurance policy covering directors and officers under which the insurer
agrees to pay, subject to certain exclusions, for any claim made against the
directors and officers of the Registrant for a wrongful act that they may
become legally obligated to pay or for which the Registrant is required to
indemnify the directors or officers.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

ITEM 22. UNDERTAKINGS.
 
  (a) The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement:
 
      (i)To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;
 
      (ii)To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high and of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than 20 percent change in
    the maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective registration statement.
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement.
 
    (2) That, for purposes of determining any liability under the Securities
  Act of 1933, each such post-effective amendment shall be deemed to be a new
  registration statement related to the securities offered therein, and the
  offering of such securities at that time shall be deemed to be the initial
  bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the Securities being registered which remain unsold at the
  termination of the Offering.
 
  (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
  (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the registrant's Certificate of Incorporation or
Bylaws, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act of 1933 and is, therefor,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment for the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.
 
  (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
