TERMS AND CONDITIONS

1. Grant of Shares. Premiere
Global Services, Inc. (the Company) hereby grants to the Grantee named on Page

forth in the Premiere Global Services, In. 1995 Stock Plan (the Plan) and in this award
agreement (this Agreement), the number of shares indicated on Page 1 hereof of the
Companys $0.01 par value common stock (the Shares). Capitalized terms used
herein and not otherwise defined shall have the meanings assigned to such terms in
the Plan.

2. Restrictions. The Shares
are subject to each of the following restrictions. Restricted Shares mean those
Shares that are subject to the restrictions imposed hereunder which restrictions have
not then expired or terminated. Restricted Shares may not be sold, transferred,
exchanged, assigned, pledged, hypothecated or otherwise encumbered. If Grantees
employment with the Company or any Affiliate terminates for any reason other than as set
forth in paragraph (b) of Section 3 hereof, then Grantee shall forfeit all of Grantees
right, title and interest in and to the Restricted Shares as of the date of employment
termination, such Restricted Shares shall revert to the Company immediately
following the event of forfeiture. The restrictions imposed under this Section 2
shall apply to all shares of the Companys common stock or other securities issued
with respect to Restricted Shares hereunder in connection with any merger,
reorganization, consolidation, recapitalization, stock dividend or other change in
corporate structure affecting the common stock of the Company.

3. Expiration and Termination
of Restrictions. The restrictions imposed under Section 2 will expire on the earliest
to occur of the following (the period prior to such expiration being referred to herein
as the Restricted Period):

| | (a) |  | As
to the fractions of the Shares  specified on page 1 hereof,  on the respective  dates
specified on page 1 hereof;  provided          Grantee is then still employed by the
Company or an Affiliate;
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b) |  | As
to all of the unvested Shares, on the date of termination of Grantees employment by
reason of death or Disability; or
| | --- |  | -------------------------------------------------------------------------------------------------------------------------

| | (c) |  | As
to all of the  unvested  Shares,  on the date of a Change in  Control  of the  Company
 (as such term is  defined  below)          provided Grantee is them still employed by
the Company or an Affiliate; or
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (d) |  | As
to the next tranche of unvested  Shares in the fraction  specified on page 1 hereof,  on
the date  termination of Grantees          employment without Cause (as such term is
defined below) prior to a Change in Control.
| | --- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For purposes of this Agreement, Cause and
Change in Control shall have the meaning as set forth in Grantees employment letter
with the Company or any of its Affiliates, as in effect from time to time.

4. Delivery of Shares. The
Shares will be registered in the name of Grantee as of the Grant Date and will be
held by the Company during the Restricted Period in certificated or uncertificated
form. If a certificate for Restricted Shares is issued during the Restricted Period
with respect to such Shares, such certificate shall be registered in the name of Grantee
and shall bear a legend in substantially the following form (in addition to any legend
required under applicable state securities laws):

This  certificate  and the shares
of stock  represented  hereby are subject to the terms and  conditions  (including
 forfeiture  and restrictions  against  transfer)  contained in a Restricted  Stock
Agreement  between the registered  owner of the shares  represented hereby  and  Premiere
 Global  Services,  Inc.  Release  from such  terms and  conditions  shall be made only
in  accordance  with the provisions of such Agreement, copies of which are on file in the
offices of Premiere Global Services, Inc.

Stock  certificates for the Shares,
 without the first above legend,  shall be delivered to Grantee or Grantees designee
upon request of Grantee after the  expiration of the  Restricted  Period,  but delivery
may be postponed for such period as may be required for the Company with reasonable
 diligence to comply if deemed advisable by the Company,  with registration  requirements
under the Securities Act of 1933,  as  amended,  listing  requirements  under the  rules
of any stock  exchange,  and  requirements  under any other law or regulation applicable
to the issuance or transfer of the Shares.

5. Voting and Dividend Rights.
Grantee, as beneficial owner of the Shares, shall have full voting and dividend
rights with respect to the Shares during and after the Restricted Period. If
Grantee forfeits any rights he or she may have under this Agreement in accordance
with Section 3, Grantee shall no longer have any rights as a shareholder with
respect to the Restricted Shares or any interest therein and Grantee shall no longer
be entitled to receive dividends on such stock. In the event that for any reason
Grantee shall have received dividends upon such stock after such forfeiture,
Grantee shall repay to the Company any amount equal to such dividends.

6. Changes in Capital
Structure. The provisions of the Plan shall apply in the case of a change in the
capital structure of the Company. Without limiting the foregoing, in the event of a
subdivision of the outstanding Stock (stock-split), a declaration of a dividend payable
in Stock, or a combination or consolidation of the outstanding Stock into a lesser
number of shares, the Shares then subject to this Agreement shall automatically be
adjusted proportionately.

7. No Right of Continued
Employment. Nothing in this Agreement shall interfere with or limit in any way the
right of the Company or any Affiliate to terminate Grantees employment at any time,
nor confer upon Grantee any right to continue in the employ of the Company or any
Affiliate.

8. Payment of Taxes. Upon
issuance of the Shares hereunder, Grantee may make an election to be taxed upon
such award under Section 83(b) of the Code. To effect such election, Grantee may file an
appropriate election with Internal Revenue Service within thirty (30) days after
award of the Shares and otherwise in accordance with applicable Treasury Regulations.
Grantee will, no later than the date as of which any amount related to the Shares first
becomes includable in Grantees gross income for federal income tax purposes, pay to
the Company, or make other arrangements satisfactory to the Committee regarding payment
of, any federal, state and local taxes of any kind required by law to be withheld
with respect to such amount. The obligations of the Company under this Agreement
will be conditional on such payment or arrangements, and the Company, and, where
applicable, its Affiliates will, to the extent permitted by law, have the right to
deduct any such taxes from any payment of any kind otherwise due to Grantee.

9. Amendment. The Committee
may amend, modify or terminate this Agreement without approval of Grantee; provided,
however, that such amendment, modification or termination shall not, without
Grantees consent, reduce or diminish the value of this award determined as if it
had been fully vested (i.e., as if all restrictions on the Shares hereunder had
expired) on the date of such amendment or termination.

10. Plan Controls. The terms
contained in the Plan are incorporated into and made a part of this Agreement and this
Agreement shall be governed by and construed in accordance with the Plan. In the
event of any actual or alleged conflict between the provisions of the Plan and the
provisions of this Agreement, the provisions of the Plan shall be controlling and
determinative.

11. Successors. This Agreement
shall be binding upon any successor of the Company, in accordance with the terms
of this Agreement and the Plan.

12. Severability. If any one or
more of the provisions contained in this Agreement is deemed to be invalid,
illegal or unenforceable, the other provisions of this Agreement will be construed
and enforced as if the invalid, illegal or unenforceable provision had never been
included.

13. Notice. Notices and
communications under this Agreement must be in writing and either personally
delivered or sent by registered or certified United States mail, return receipt
requested, postage prepaid. Notices to the Company must be addressed to:
