Security Entitlement to the Pledged Securities through action by the WAXS
Securities Intermediary, as confirmed (in writing or electronically or
otherwise in accordance with standard industry practice) to the Trustee by the
WAXS Securities Intermediary (i) indicating by book-entry that the Pledged
Securities and all Security Entitlements thereto have been credited to the
Pledge Account, or (ii)


                                       7
   11

acquiring the Pledged Securities and all Security Entitlements thereto for the
Trustee and accepting the same for credit to the Pledge Account.

                  (b)    Prior to or concurrently with the execution and
delivery hereof and prior to the transfer to the Trustee of the Pledged
Securities (or acquisition by the Trustee of any Security Entitlement thereto),
as provided in subsection (a) of this Section 3, the Trustee and the WAXS
Securities Intermediary shall establish the Pledge Account on the books of the
WAXS Securities Intermediary as Securities Account segregated from all other
custodial or collateral accounts such account to be maintained either (i)
directly at its offices located at 999 Peachtree Street, N.E., Suite 1100,
Atlanta, Georgia 30309 or (ii) through a "Securities Account" maintained by the
WAXS Securities Intermediary at the FRBB, as Securities Intermediary. Upon
transfer of the Pledged Securities to the Trustee (or the Trustee's acquisition
of a Security Entitlement thereto), as confirmed to the WAXS Securities
Intermediary by FRBB or another securities intermediary, the WAXS Securities
Intermediary shall make appropriate book entries indicating that the Pledged
Securities and/or such Security Entitlement have been credited to and are held
in the Pledge Account. Subject to the other terms and conditions of this Pledge
Agreement, all funds or other property held by the Trustee pursuant to this
Pledge Agreement shall be held in the Pledge Account or the Cash Collateral
Account subject (except as expressly provided in Section 6 hereof) to the
exclusive dominion and control (including, without limitation, Securities
Control) of the Trustee and exclusively for the benefit of the Trustee and for
the ratable benefit of the Holders of the Notes and segregated from all other
funds or other property otherwise held by the Trustee.

                  (c)    All Collateral shall be retained in the Pledge Account
or the Cash Collateral Account pending disbursement pursuant to the terms
hereof.

                  (d)    Concurrently with the execution and delivery of this
Pledge Agreement, the Trustee is delivering to the Pledgor and the Initial
Purchasers a duly executed certificate, in the form of Exhibit A hereto, of an
officer of the Trustee, confirming the Trustee's establishment and maintenance
of the Pledge Account with the WAXS Securities Intermediary and its receipt and
holding of the Pledge Securities or a Security Entitlement thereto and the
crediting of the Pledged Securities or such Security Entitlement to the Pledge
Account, all in accordance with this Pledge Agreement.

                  (e)    Concurrently with the execution and delivery of this
Pledge Agreement, the Pledgor is delivering to the Trustee an opinion of a
nationally recognized firm of independent public accountants, selected by the
Pledgor, substantially in the form of Exhibit B hereto.

                  (f)    Concurrently with the execution and delivery of this
Pledge Agreement, the Pledgor is delivering to the Trustee financing statements
in form acceptable for filing under


                                       8
   12

the UCC of the State of New York, [__] and the State of Georgia, covering the
Collateral described in this Pledge Agreement.

                  SECTION 4. Delivery of Collateral Other than U.S. Government
Obligations.

                  (a)    Collateral consisting of cash will be deemed to be
delivered to the Trustee (such that the Trustee will have an enforceable lien
and security interest thereon and therein), when it has been (and for so long
as it shall remain) deposited in or credited to the Cash Collateral Account.

                  (b)    Collateral consisting of Cash Equivalents (other than
U.S. Government Obligations) will be deemed to be delivered to the Trustee
(such that the Trustee will have an enforceable lien and security interest
thereon and therein), when they have been (and for so long as they shall
remain) deposited in or credited to either Collateral Account.

                  (c)    Collateral consisting of Securities (other than U.S.
Government Obligations) will be deemed delivered to the Trustee when the WAXS
Securities Intermediary (A) shall indicate by book entry that such Securities
have been credited to the Pledge Account or (B) shall receive such Security (or
a Financial Asset based on such Security) for the Trustee from or at the
direction of the Pledgor, and shall accept such Security (or such Financial
Asset) for credit to such Collateral Account;

                  (d)    Collateral consisting of Securities and represented or
evidenced by certificates or instruments, will be deemed delivered to the
Trustee when all such certificates or instruments representing or evidencing
the Collateral, including, without limitation, amounts invested as provided in
Section 5, shall be delivered to the WAXS Securities Intermediary and held by
or on behalf of the Trustee pursuant hereto and shall be in registered form and
specially indorsed to the Trustee by an effective indorsement, all in form and
substance sufficient to convey a valid security interest in such Collateral to
the Trustee or shall be credited to the Pledge Account.

                  SECTION 5. Investing of Amounts in the Collateral Accounts.
If at any time, any amounts shall exist in the Collateral Accounts uninvested,
and if directed in writing by the Pledgor, the Trustee will, subject to the
provisions of Section 6 and Section 13, (a) invest such amounts on deposit in
the Collateral Accounts in such Cash Equivalents in the name of the Trustee as
the Pledgor may select and (b) invest interest paid on the Cash Equivalents
referred to in clause (a) above, and reinvest other proceeds of any such Cash
Equivalents that may mature or be sold, in each case in such Cash Equivalents
in the name of the Trustee, as the Pledgor may select and the Trustee may
approve (the Cash Equivalents referred to in clauses (a) and (b) above,
together with the Pledged Securities, being collectively referred to herein as
"Collateral


                                       9
   13

Investments"). Except as otherwise provided in Sections 11 and 12, the Trustee
shall not be liable for any loss in the investment or reinvestment of amounts
held in the Collateral Accounts.

                  SECTION 6. Disbursements. The Trustee shall hold the
Collateral in the Collateral Accounts and release the same, or a portion
thereof, only as follows:

                  (a)    At least one Business Day prior to the due date of any
of the scheduled interest payments on the Notes on or prior to January 15,
2001, the Pledgor may, pursuant to written instructions executed by the Pledgor
(an "Issuer Order"), direct the Trustee to release from the Collateral Accounts
and pay to the Holders of the Notes proceeds sufficient to provide for payment
in full (or, with respect to the interest payment date on January 15, 2001, in
part) of such interest then due on the Notes; provided, however, that in the
event Collateral is required to be liquidated, the Pledgor will give the
Trustee at least three Business Days' notice. Upon receipt of an Issuer Order,
the Trustee will take any action necessary to provide for the payment of the
interest on the Notes to the Holders of the Notes in accordance with the
payment provisions of the Indenture from (and to the extent of) proceeds of the
Collateral in the Collateral Accounts. Nothing in this Section 6 shall affect
the Trustee's rights to apply the Collateral to the payments of amounts due on
the Notes upon acceleration thereof.

                  (b)    If the Pledgor makes any interest payment or portion
of an interest payment for which the Collateral is security from a source of
funds other than the Collateral Accounts ("Pledgor Funds"), the Pledgor may,
after payment in full of such interest payment or portion thereof from proceeds
of the Collateral or such Pledgor Funds or both, direct the Trustee by Issuer
Order to release to the Pledgor or to another party at the direction of the
Pledgor (the "Pledgor's Designee") proceeds from the Collateral Accounts in an
amount less than or equal to the amount of Pledgor Funds applied to such
interest payment. Upon receipt of such Issuer Order by the Trustee, the Trustee
shall pay over to the Pledgor or the Pledgor's Designee, as the case may be,
the requested amount from proceeds in the Collateral Accounts. Concurrently
with any release of funds to the Pledgor pursuant to this Section 6(b), the
Pledgor shall deliver to the Trustee a certificate signed by an officer of the
Pledgor stating that the Pledgor has made the interest payment from a source of
funds other than the Pledge Account, and that such release has been duly
authorized by the Pledgor and will not contravene any provision of applicable
law or Certificate of Incorporation or the By-laws of the Pledgor or any
material agreement or other material instrument binding upon the pledgor or any
of its subsidiaries or any judgment, order or decree of any governmental body,
agency or court having jurisdiction over the Pledgor or any of its subsidiaries
or result in the creation or imposition of any Lien on any assets of the
Pledgor, except for the security interest granted under the Pledge Agreement.

                  (c)    At least one Business Day prior to the due date of any
of the scheduled interest payments on the Notes on or prior to January 15,
2001, the Pledgor covenants to give the Trustee (by Issuer Order) notice as to
whether payment of interest will be made pursuant to Section 6(a) or 6(b) and
as to the respective amounts of interest that will be paid pursuant to


                                      10
   14

Section 6(a) or 6(b); provided, however, that, in the event Collateral is
required to be liquidated, the Pledgor will give the Trustee at least three
Business Days' notice. If no such notice is given, the Trustee will, subject to
Section 6(d), act pursuant to Section 6(a) as if it had received an Issuer
Order pursuant thereto for the payment in full of the interest then due.

                  (d)    The Trustee shall not be required to liquidate any
Collateral Investments in order to make any scheduled payment of interest or
any release hereunder unless instructed to do so by Issuer Order or pursuant to
Section 13 hereof.

                  (e)    Upon the Termination Date, the security interest in
the Collateral evidenced by this Pledge Agreement will automatically terminate
and be of no further force and effect and the Collateral, upon receipt by the
Trustee of an Issuer Order, shall promptly be paid over and transferred to the
Pledgor.

                  (f)    In the event that the Collateral held in the Pledge
Account exceeds 100% of the amount sufficient, in the opinion of a nationally
recognized firm of independent public accountants selected by the Pledgor, to
provide for payment of the scheduled interest due on the Notes in an amount
equal to the Pledge Amount (or, in the event an interest payment or payments
have been made, the Pledge Amount less an amount equal to any interest
previously paid) the Trustee shall release to the Pledgor, at the Pledgor's
written request, accompanied by an opinion prepared by a nationally recognized
firm of independent public accountants, any such excess Collateral.

                  (g)    Upon the release of any Collateral from the Pledge
Account, in accordance with the terms of this Pledge Agreement, the security
interest evidenced by this Pledge Agreement in such released Collateral will
automatically terminate and be of no further force and effect.

                  (h)    Nothing contained in Section 1, Section 13, this
Section 6 or any other Provision of this Pledge Agreement shall (i) afford the
Pledgor any right to issue Entitlement Orders with respect to any Security
Entitlement to the Pledge Securities or Collateral Investments or any
Securities Account in which any such Security Entitlement may be carried, or
otherwise afford the Pledgor control of any such Security Entitlement or (ii)
otherwise give rise to any rights of the Pledgor with respect to the Collateral
Investments, any Security Entitlement thereto or any Securities Account in
which any such Security Entitlement may be carried, other than the Pledgor's
rights under this Pledge Agreement as the beneficial owner of Collateral
pledged to and subject to the exclusive dominion and control (including,
without limitation, Securities Control) (except as expressly provided in this
Section 6) of the Trustee in its capacity as such (and not as a Securities
Intermediary). The Pledgor acknowledges, confirms and agrees


                                      11
   15

that the Trustee holds a Security Entitlement to the Collateral Investments
solely as trustee for the Holders of the Notes and not as a Securities
Intermediary for the Pledgor.

                  SECTION 7. Representations and Warranties. The Pledgor hereby
represents and warrants, as of the date hereof, that:

                  (a)    The execution and delivery by the Pledgor of, and the
performance by the Pledgor of its obligations under, this Pledge Agreement will
not contravene any provision of applicable law or the Certificate of
Incorporation or By-laws of the Pledgor or any material agreement or other
material instrument binding upon the Pledgor or any of its subsidiaries or any
judgment, order or decree of any governmental body, agency or court having
jurisdiction over the Pledgor or any of its subsidiaries, or result in the
creation or imposition of any Lien on any assets of the Pledgor, except for the
security interests granted under this Pledge Agreement; no consent, approval,
authorization or order of, or qualification with, any governmental body or
agency is required (i) for the performance by the Pledgor of its obligations
under this Pledge Agreement, (ii) for the pledge by the Pledgor of the
Collateral pursuant to this Pledge Agreement or (iii) except for any such
consents, approvals, authorizations or orders required to be obtained by the
Trustee (or the Holders) for reasons other than the consummation of this
transaction, for the exercise by the Trustee of the rights provided for in this
Pledge Agreement or the remedies in respect of the Collateral pursuant to this
Pledge Agreement.

                  (b)    The Pledgor is the beneficial owner of the Collateral,
free and clear of any Lien or claims of any person or entity (except for the
security interests granted under this Pledge Agreement). No financing statement
covering the Pledgor's interest in the Collateral is on file in any public
office other than the financing statements, if any, filed pursuant to this
Pledge Agreement.

                  (c)    This Pledge Agreement has been duly authorized,
validly executed and delivered by the Pledgor and (assuming the due
authorization and valid execution and delivery of this Pledge Agreement by the
Trustee and enforceability of the Pledge Agreement against the Trustee in
accordance with its terms) constitutes a valid and binding agreement of the
Pledgor, enforceable against the Pledgor in accordance with its terms, except
as (i) the enforceability hereof may be limited by bankruptcy, insolvency,
fraudulent conveyance, preference, reorganization, moratorium or similar laws
now or hereafter in effect relating to or affecting the rights or remedies of
creditors generally, (ii) the availability of equitable remedies may be limited
by equitable principles of general applicability and the discretion of the
court before which any proceeding therefor may be brought, (iii) the
exculpation provisions and rights to indemnification hereunder may be limited
by U.S. federal and state securities laws and public policy considerations and
(iv) the waiver of rights and defenses contained in Section 13(b), Section
17.11 and Section 17.15 hereof may be limited by applicable law.


                                      12
   16

                  (d)    Upon the delivery to the Trustee of the Collateral in
accordance with the procedures described in Section 3 and Section 4 hereof, the
pledge of and grant of a security interest in the Collateral securing the
payment of the Obligations for the benefit of the Trustee and the Holders of
the Notes will constitute a valid, first priority, perfected security interest
in such Collateral (except, with respect to Proceeds, only to the extent
permitted by Section 9-306 of the UCC), enforceable as such against all
creditors of the Pledgor and any persons purporting to purchase any of the
Collateral from the Pledgor, except in each case as enforcement may be affected
by general equitable principles (whether considered in a proceeding in equity
or at law) and other than as permitted by the Indenture.

                  (e)    There are no legal or governmental proceedings pending
or, to the best of the Pledgor's knowledge, threatened to which the Pledgor or
any of its subsidiaries is a party or to which any of the properties of the
Pledgor or any of its subsidiaries is subject that would materially adversely
affect the power or ability of the Pledgor to perform its obligations under
this Pledge Agreement or to consummate the transactions contemplated hereby.

                  (f)    The pledge of the Collateral pursuant to this Pledge
Agreement is not prohibited by law or governmental regulation (including,
without limitation, Regulations G, T, U and X of the Board of Governors of the
Federal Reserve System) applicable to the Pledgor.

                  (g)    No Event of Default (as defined herein) exists.

                  SECTION 8. Further Assurances. The Pledgor will, promptly
upon the request by the Trustee (which request the Trustee may submit at the
direction of the Holders of a majority in aggregate principal amount of the
Notes then outstanding), execute and deliver or cause to be executed and
delivered, or use its reasonable best efforts to procure, all assignments,
instruments and other documents, all in form and substance reasonably
satisfactory to the Trustee, deliver any instruments to the Trustee and take
any other actions that are necessary or desirable to perfect, continue the
perfection of, or protect the first priority of the Trustee's security interest
in and to the Collateral, to protect the Collateral against the rights, claims
or interests of third persons (other than any such rights, claims or interests
created by or arising through the Trustee) or to effect the purposes of this
Pledge Agreement. The Pledgor also hereby authorizes the Trustee to file any
financing or continuation statements in the United States with respect to the
Collateral without the signature of the Pledgor (to the extent permitted by
applicable law). The Pledgor will promptly pay all reasonable costs incurred in
connection with any of the foregoing within 45 days of receipt of an invoice
therefor. The Pledgor also agrees, whether or not requested by the Trustee, to
use its reasonable best efforts to perfect or continue the perfection of, or to
protect the first priority of, the Trustee's security interest in and to the
Collateral, and to protect the Collateral against the rights, claims or
interests of third persons (other than any such rights, claims or interests
created by or arising through the Trustee).


                                      13
   17

                  SECTION 9. Covenants. The Pledgor covenants and agrees with
the Trustee and the Holders of the Notes that from and after the date of this
Pledge Agreement until the Termination Date:

                  (a)    that it will not (i) (and will not purport to) sell or
otherwise dispose of, or grant any option or warrant with respect to, any of
the Collateral nor (ii) create or permit to exist any Lien upon or with respect
to any of the Collateral (except for the security interests granted under this
Pledge Agreement and any Lien created by or arising through the Trustee) and at
all times will be the sole beneficial owner of the Collateral; and

                  (b)    that it will not (i) enter into any agreement or
understanding that restricts or inhibits or purports to restrict or inhibit the
Trustee's rights or remedies hereunder, including, without limitation, the
Trustee's right to sell or otherwise dispose of the Collateral or (ii) fail to
pay or discharge any tax, assessment or levy of any nature with respect to the
Collateral not later than five days prior to the date of any proposed sale
under any judgment, writ or warrant of attachment with respect to the
Collateral.

                  SECTION 10. Power of Attorney. In addition to all of the
powers granted to the Trustee pursuant to the Indenture, subject to the terms
of this Pledge Agreement, the Pledgor hereby appoints and constitutes the
Trustee as the Pledgor's attorney-in-fact (with full power of substitution) to
exercise to the fullest extent permitted by law all of the following powers
upon and at any time after the occurrence and during the continuance of an
Event of Default: (a) collection of proceeds of any Collateral; (b) conveyance
of any item of Collateral to any purchaser thereof; (c) giving of any notices
or recording of any Liens under Section 3 hereof; and (d) paying or discharging
taxes or Liens levied or placed upon the Collateral, the legality or validity
thereof and the amounts necessary to discharge the same to be determined by the
Trustee in its sole reasonable discretion, and such payments made by the
Trustee to become part of the Obligations of the Pledgor to the Trustee, due
and payable immediately upon demand. The Trustee's authority under this Section
10 shall include, without limitation, the authority to endorse and negotiate
any checks or instruments representing proceeds of Collateral in the name of
the Pledgor, execute and give receipt for any certificate of ownership or any
document constituting Collateral, transfer title to any item of Collateral,
sign the Pledgor's name on all financing statements (to the extent permitted by
applicable law) or any other documents deemed necessary or appropriate by the
Trustee in its reasonable discretion to preserve, protect or perfect the
security interest in the Collateral and to file the same, prepare, file and
sign the Pledgor's name on any notice of Lien, and to take any other actions
arising from or incident to the powers granted to the Trustee in this Pledge
Agreement. This power of attorney is coupled with an interest and is
irrevocable by the Pledgor.

                  SECTION 11. No Assumption of Duties; Reasonable Care. The
rights and powers granted to the Trustee hereunder are being granted in order
to preserve and protect the


                                      14
   18

security interest of the Trustee and the Holders of the Notes in and to the
Collateral granted hereby and shall not be interpreted to, and shall not impose
any duties on, the Trustee in connection therewith other than those expressly
provided herein or imposed under applicable law. Except as provided by
applicable law or by the Indenture, the Trustee shall be deemed to have
exercised reasonable care in the custody and preservation of the Collateral in
its possession if the Collateral is accorded treatment substantially equal to
that which the Trustee accords similar property held by the Trustee for similar
accounts, it being understood that the Trustee in its capacity as such shall
not have any responsibility for (a) ascertaining or taking action with respect
to calls, conversions, exchanges, maturities or other matters relative to any
Collateral, whether or not the Trustee has or is deemed to have knowledge of
such matters, (b) taking any necessary steps to preserve rights against any
parties with respect to any Collateral or (c) investing or reinvesting any of
the Collateral; provided, however, that nothing contained in this Pledge
Agreement shall relieve the Trustee of any responsibilities as a securities
intermediary under applicable law.

                  SECTION 12.  Indemnity.

                  (a)    The Pledgor shall indemnify, hold harmless and defend
the Trustee and its directors, officers, agents, employees and attorneys from
and against any and all claims, actions, obligations, liabilities and expenses,
including reasonable defense costs, reasonable investigative fees and costs,
and reasonable legal fees and damages arising from the Trustee's performance as
Trustee under this Pledge Agreement, except to the extent that such claim,
action, obligation, liability or expense is directly attributable to the bad
faith, gross negligence or wilful misconduct of such indemnified person. The
provisions of this Section 12 shall survive termination of this Pledge
Agreement and the resignation and removal of the Trustee.

                  (b)    The Pledgor shall indemnify, hold harmless and defend
the WAXS Securities Intermediary and its directors, officers, agents, employees
and attorneys from and against any and all claims, actions, obligations,
liabilities and expenses, including reasonable defense costs, reasonable
investigative fees and costs, and reasonable legal fees and damages arising
from the WAXS Securities Intermediary's performance as WAXS Securities
Intermediary under this Pledge Agreement, except to the extent that such claim,
action, obligation, liability or expense is directly attributable to the bad
faith, gross negligence or wilful misconduct of such indemnified person. The
provisions of this Section 12 shall survive termination of this Pledge
Agreement and the resignation and removal of the WAXS Securities Intermediary.

                  SECTION 13. Remedies upon Event of Default. If any Event of
Default under the Indenture or default hereunder (any such Event of Default or
default being referred to in this Pledge Agreement as an "Event of Default")
shall have occurred and be continuing:


                                      15
   19

                  (a)    The Trustee and the Holders of the Notes shall have,
in addition to all other rights given by law or by this Pledge Agreement or the
Indenture, all of the rights and remedies with respect to the Collateral of a
secured party under the UCC in effect in the States of New York and Georgia at
that time. In addition, with respect to any Collateral that shall then be in or
shall thereafter come into the possession or custody of the Trustee, the
Trustee may and, at the direction of the Holders of a majority in aggregate
principal amount of the Notes then outstanding, shall appoint a broker or other
expert to sell or cause the same to be sold at any broker's board or at public
or private sale, in one or more sales or lots, at such price or prices such
broker or other expert may deem best, for cash or on credit or for future
delivery, without assumption of any credit risk. The purchaser of any or all
Collateral so sold shall thereafter hold the same absolutely, free from any
claim, encumbrance or right of any kind whatsoever created by or through the
Pledgor. Unless any of the Collateral threatens, in the reasonable judgment of
the Trustee, to decline speedily in value, the Trustee will give the Pledgor
reasonable notice of the time and place of any public sale thereof, or of the
time after which any private sale or other intended disposition is to be made.
Any sale of the Collateral conducted in conformity with reasonable commercial
practices of banks, insurance companies, commercial finance companies, or other
financial institutions disposing of property similar to the Collateral shall be
deemed to be commercially reasonable. Any requirements of reasonable notice
shall be met if such notice is mailed to the Pledgor as provided in Section
17.1 hereof at least ten (10) days before the time of the sale or disposition.
The Trustee or any Holder of Notes may, in its own name or in the name of a
designee or nominee, buy any of the Collateral at any public sale and, if
permitted by applicable law, at any private sale. All expenses (including court
costs and reasonable attorneys' fees, expenses and disbursements) of, or
incident to, the enforcement of any of the provisions hereof shall be
recoverable from the proceeds of the sale or other disposition of the
Collateral.

                  (b)    The Pledgor further agrees to use its reasonable best
efforts to do or cause to be done all such other acts as may be necessary to
make such sale or sales of all or any portion of the Collateral pursuant to
this Section 13 valid and binding and in compliance with any and all other
applicable requirements of law. The Pledgor further agrees that a breach of any
of the covenants contained in this Section 13 will cause irreparable injury to
the Trustee and the Holders of the Notes, that the Trustee and the Holders of
the Notes have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this Section 13 shall be
specifically enforceable against the Pledgor, and the Pledgor hereby waives and
agrees not to assert any defenses against an action for specific performance of
such covenants except for a defense that no Event of Default has occurred.

                  SECTION 14. Expenses. The Pledgor will upon demand pay to the
Trustee the amount of any and all reasonable expenses, including, without
limitation, the reasonable fees, expenses and disbursements of its counsel,
experts and agents retained by the Trustee, that the Trustee may incur in
connection with (a) the review, negotiation and administration of this Pledge
Agreement, (b) the custody or preservation of, or the sale of, collection from,
or other


                                      16
   20

realization upon, any of the Collateral, (c) the exercise or enforcement of any
of the rights of the Trustee and the Holders of the Notes hereunder or (d) the
failure by the Pledgor to perform or observe any of the provisions hereof.

                  SECTION 15. Security Interest Absolute. All rights of the
Trustee and the Holders of the Notes and security interests hereunder, and all
obligations of the Pledgor hereunder, shall be absolute and unconditional
irrespective of:

                  17.2 No Adverse Interpretation of Other Agreements. This
Pledge Agreement may not be used to interpret another pledge, security or debt

                  17.3 Severability. The provisions of this Pledge Agreement
are severable, and if any clause or provision shall be held invalid, illegal or
unenforceable in whole or in part in any jurisdiction, then such invalidity or

provision in any other jurisdiction or any other clause or provision of this
Pledge Agreement in any jurisdiction.

                  17.4 Headings. The headings in this Pledge Agreement have

                  17.5 Counterpart Originals. This Pledge Agreement may be
signed in two or more counterparts, each of which shall be deemed an original,
but all of which shall together constitute one and the same agreement.

                  17.6 Benefits of Pledge Agreement. Nothing in this Pledge
Agreement, express or implied, shall give to any person, other than the parties
hereto and their successors hereunder, and the Holders of the Notes, any
benefit or any legal or equitable right, remedy or claim under this Pledge
Agreement.

                  17.7 Amendments, Waivers and Consents. Any amendment or
waiver of any provision of this Pledge Agreement and any consent to any
departure by the Pledgor from any provision of this Pledge Agreement shall be
effective only if made or duly given in compliance with all of the terms and
provisions of the Indenture, and neither the Trustee nor any Holder of Notes
shall be deemed, by any act, delay, indulgence, omission or otherwise, to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default or in any breach of any of the terms and conditions hereof.
Failure of the Trustee or any Holder of Notes to exercise, or delay in
exercising, any right, power or privilege hereunder shall not preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Trustee or any Holder of Notes of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy that the Trustee or such Holder of Notes would otherwise have
on any future occasion. The rights and remedies herein provided are cumulative,
may be exercised singly or concurrently and are not exclusive of any rights or
remedies provided by law.

                  17.8 Interpretation of Agreement. All terms not defined
herein or in the Indenture shall have the meaning set forth in the UCC, except
where the context otherwise requires. To the extent a term or provision of this
Pledge Agreement conflicts with the Indenture, the Indenture shall control with
respect to the subject matter of such term or provision. Acceptance of or
acquiescence in a course of performance rendered under this Pledge Agreement
shall not be relevant to determine the meaning of this Pledge Agreement even
though the accepting or acquiescing party had knowledge of the nature of the
performance and opportunity for objection.

                  17.9 Continuing Security Interest; Termination.

                  (a) This Pledge Agreement shall create a continuing security
interest in and to the Collateral and shall, unless otherwise provided in the
Indenture or in this Pledge Agreement, remain in full force and effect until
the payment in full in cash of the Obligations. This Pledge Agreement shall be
binding upon the Pledgor, its transferees, successors and assigns, and shall
inure, together with the rights and remedies of the Trustee hereunder, to the
benefit of the Trustee, the Holders of the Notes and their respective
successors, transferees and assigns.

reassign and redeliver to the Pledgor all of the Collateral hereunder that has
not been sold, disposed of, retained or applied by the Trustee in accordance
with the terms of this Pledge Agreement and the Indenture. Such reassignment
and redelivery shall be without warranty by or recourse to the Trustee in its
capacity as such, except as to the absence of any Liens on the Collateral
created by or arising through the Trustee, and shall be at the reasonable
expense of the Pledgor.

                  17.10 Survival Provisions. All representations, warranties
and covenants of the Pledgor contained herein shall survive the execution and
delivery of this Pledge Agreement, and shall terminate only upon the
termination of this Pledge Agreement. The obligations of the Pledgor under
Sections 12 and 14 hereof shall survive the termination of this Pledge
Agreement.

                  17.11 Waivers. The Pledgor waives presentment and demand for
payment of any of the Obligations, protest and notice of dishonor or default
with respect to any of the Obligations, and all other notices to which the
Pledgor might otherwise be entitled, except as otherwise expressly provided
herein or in the Indenture.

                  17.12  Authority of the Trustee.

                  (a)    The Trustee shall have and be entitled to exercise all
powers hereunder that are specifically granted to the Trustee by the term
hereof, together with such powers as are reasonably incident thereto. The
Trustee may perform any of its duties hereunder or in connection with the
Collateral by or through agents or employees and shall be entitled to retain
counsel and to act in reliance upon the advice of counsel concerning all such
matters. Except as otherwise expressly provided in this Pledge Agreement or the
Indenture, neither the Trustee nor any director, officer, employee, attorney or
agent of the Trustee shall be liable to the Pledgor for any action taken or
omitted to be taken by the Trustee, in its capacity as Trustee, hereunder,
except for its own bad faith, gross negligence or willful misconduct, and the
Trustee shall not be responsible for the validity, effectiveness or sufficiency
hereof or of any document or security furnished pursuant hereto. The Trustee
and its directors, officers, employees, attorneys and agents shall be entitled
to rely on any communication, instrument or document believed by it or them to
be genuine and correct and to have been signed or sent by the proper person or
persons. The Trustee shall have no duty to cause any financing statement or
continuation statement to be filed in respect of the Collateral.

responsibilities of the Trustee under this Pledge Agreement with respect to any
action taken by the Trustee or the

   25

exercise or non-exercise by the Trustee of any option, right, request, judgment
or other right or remedy provided for herein or resulting or arising out of
this Pledge Agreement shall, as between the Trustee and the Holders of the
Notes, be governed by the Indenture and by such other agreements with respect
thereto as may exist from time to time among them, but, as between the Trustee
and the Pledgor, the Trustee shall be conclusively presumed to be acting as
agent for the Holders of the Notes with full and valid authority so to act or
refrain from acting, and the Pledgor shall not be obligated or entitled to make
any inquiry respecting such authority.

                  17.13 Final Expression. This Pledge Agreement, together with
the Indenture and any other agreement executed in connection herewith, is
intended by the parties as a final expression of this Pledge Agreement and is
intended as a complete and exclusive statement of the terms and conditions

individual Holders of the Notes pursuant to Section 607 of the Indenture;

                  the Pledged Securities and the other Collateral are not, and
                  the Trustee's security entitlement to the Collateral is not,
                  to the actual knowledge of the corporate trust officer having
                  responsibility for the administration of this Indenture on
                  behalf of the Trustee, subject to any Lien granted by or to
                  or arising through or in favor of any Securities Intermediary
                  (including, without limitation, the Trustee at the WAXS
                  Securities Intermediary, or the Federal Reserve Bank of
                  Richmond) through which the Trustee derives its security
                  entitlement to the Collateral.

         2.       The Trustee has not caused or permitted the Collateral
                  Account or its Security Entitlement thereto to become subject
                  to any Lien created by or arising through the Trustee.

                                                                      EXHIBIT B


INDEPENDENT ACCOUNTANTS' REPORT ON APPLYING AGREED-UPON PROCEDURES

To the Board of Directors
World Access, Inc.

We understand that $________ 13.25% Senior Notes due 2008 ("Notes") of World
Access, Inc. (the "Issuer"), are to be issued on __________________. We also
understand that First Union National Bank (the "Trustee") will hold the
Securities listed on the attached Annex I (the "Securities") pursuant to
Section 6 of the Collateral Pledge and Security Agreement, between the Issuer
and the Trustee, dated as of ___________________ (the "Pledge Agreement").

We have been requested by the Issuer and the Trustee (collectively, the
"Intended Users") to prove the arithmetic accuracy of the computations shown on
the attached schedules, prepared by the Issuer.

We have performed the procedures enumerated below, which were agreed to by the
Intended Users, solely to assist you and the Trustee with respect to proving
the arithmetic accuracy of the computations shown on the attached schedules.
This engagement to apply agreed-upon procedures was performed in accordance
with standards established by the American Institute of Certified Public
Accountants. The sufficiency of the procedures is solely the responsibility of
the specified users of the report. Consequently, we make no representations
regarding the sufficiency of the procedures described below either for the
purpose for which this report has been requested or for any other purpose. The
procedures that we performed and our findings are as follows:

1.       We have proved the arithmetic accuracy of the computations of the
         Pledge Amount (as defined in the Pledge Agreement), as shown on the
         attached Annex II, which was prepared by the Issuer.

2.       We have proved the arithmetic accuracy of the computation of the
         scheduled receipts of maturing principal and interest to be received
         from the Securities and cash on deposit as shown on the attached Annex
         I, which was prepared by the Issuer. Other than proving such
         arithmetic accuracy, we have not confirmed or otherwise verified the
         information on that schedule.

3.       We recomputed each amount in the net cash flow column by deducting
         each amount in the interest payment column from each amount in the
         total available column, individually and in total.

In performing the above calculations, we have relied solely on the data set
forth in the attached schedules prepared and provided to us by the Issuer. The
scope of our engagement did not include


                                      B-1
   34

verification of any underlying data, assumptions or definitions necessary to
derive the calculations. Such underlying data, assumptions and definitions
including, but are not limited to the following:

       1.     The principal amounts, coupon rates, and the related maturities
              for the Securities and Notes; and

       2.     Interest start dates, maturity dates, and interest payment dates
              for the Securities and the Notes.

We were not engaged to, and did not, perform and audit, the objective of which
would be the expression of an opinion on the specified elements, accounts, or
items included in the attached schedules. Accordingly, we do not express such
an opinion. Had we performed additional procedures, other matters might have
come to our attention that would have been reported to you.

This report is intended solely for the use of the Intended Users listed above
and should not be used by those who have not agreed to the procedures and taken
responsibility for the sufficiency of the procedures for their purposes.
