(ii) in the event the Reorganization is consummated on the Closing Date, neither
the Trustee nor any other person or entity shall have any claim or cause of
action of any nature whatsoever against BTI under or pursuant to this Pledge and
Security Agreement, including without limitation any such claim or cause of
action arising prior to consummation of the Reorganization.

                  SECTION 3. Delivery of Collateral. All certificates or
instruments representing or evidencing the Collateral, including, without
limitation, amounts invested as provided in Section 5, shall be delivered to and
held by or on behalf of the Trustee pursuant hereto and shall be in suitable

instruments of transfer or assignment in blank, all in form and substance
sufficient to establish and maintain in favor of the Trustee a valid security
interest in such Collateral, and shall be credited to a securities account (the
"Collateral Investments Account") designated by the Trustee.

                  SECTION 4. Maintaining the Cash Collateral Account. (a) So
long as any Obligation shall remain unpaid, the Cash Collateral Account shall be
maintained with the Trustee.

                  (b) It shall be a term and condition of the Cash Collateral
Account, notwithstanding any term or condition to the contrary in any other
agreement relating to the Cash Collateral Account, and except as otherwise
provided by the provisions of Section 7 and Section 14 hereof, that no amount
(including interest on Collateral Investments) shall be paid or released to or
for the account of, or withdrawn by or for the account of, the Pledgor or any
other Person from the Cash Collateral Account.

                  The Cash Collateral Account shall be subject to such
applicable laws, and such applicable regulations of the Board of Governors of
the Federal Reserve System and of any other appropriate banking or governmental
authority, as may now or hereafter be in effect.

                  SECTION 5. Investing of Amounts in the Cash Collateral
Account. If directed by the Pledgor in writing, the Trustee will, subject to the
provisions of Section 7 and Section 14 hereof, from time to time (a) invest
amounts on deposit in the Cash Collateral Account in such Cash Equivalents, each
in the name of or for the account 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, each in the name of or for
the account of the Trustee, as the Pledgor may select (the Cash Equivalents
referred to in clauses (a) and (b) above being collectively "Collateral
Investments"); provided, however, that following






                                                         6

disbursement of proceeds by the Trustee in accordance with both Section 7(c) and
Section 7(e), the amount on deposit in the Collateral Investments Account must
include U.S. Government Securities sufficient, in the opinion of a nationally
recognized firm of independent public accountants selected by the Pledgor, to
provide for the payment in full of the first six scheduled interest payments on
all of the Notes then outstanding (including any interest that may be due in the
event the Exchange Offer is not consummated or the Shelf Registration Statement
is not declared effective as required by the Registration Rights Agreement).
Interest and proceeds that are not invested or reinvested in Collateral
Investments as provided above shall be deposited and held in the Cash Collateral
Account. The Trustee shall in no event be liable for any loss in the investment
or reinvestment of amounts held in the Cash Collateral Account.

                  SECTION 6. Delivery of Collateral Investments; Filing. (a) The
Trustee shall become the holder of the Collateral Investments (or applicable
security entitlements thereto) through the following delivery procedures: (i) in
the case of Collateral Investments which are certificated securities in
registered form, delivery of the applicable certificate(s), specially endorsed
to the Trustee or registered in the name of the Trustee, to the possession of
(A) the Trustee, (B) a securities intermediary or financial intermediary acting
on behalf of the Trustee, or (C) another person, other than a securities
intermediary or financial intermediary, which person acknowledges that it holds
for the Trustee; (ii) in the case of Collateral Investments which are
uncertificated securities, registration of one of the following as owner of such
uncertificated securities: the Trustee or a person designated by the Trustee, or
person other than a securities intermediary or financial intermediary, that
becomes the registered owner of such uncertificated securities and acknowledges
that it holds the same for the Trustee; and (iii) in the case of Collateral
Investments in the form of Government Book-Entry Securities, the making by a
financial intermediary or securities intermediary (other than a clearing
corporation) to whose account such Government Book-Entry Securities have been
credited on the books of a Federal Reserve Bank (or on the books of another such
financial intermediary or securities intermediary (other than a clearing
corporation)), of book entries indicating that such Government Book-Entry
Securities have been credited to an account of the Trustee, and the sending by
such financial intermediary or securities intermediary to the Trustee of
confirmation of such transfer to the Trustee's account.

                  (b) Prior to receiving any Collateral Investments (or any
security entitlements thereto), as provided in subsection (a) of this Section 6,
the Trustee shall establish the Collateral Investments Account on its books as
an account segregated from all other custodial or collateral accounts at its
office at 100 Wall Street, New York, New York, 10005. Upon delivery of any
Collateral Investments to the Trustee (or the Trustee's acquisition of a
security entitlement thereto), the Trustee shall make appropriate book entries
indicating that such Collateral Investment and/or such security entitlement has
been credited to and is held in the Collateral Investments Account. Subject to
the terms and conditions of this Pledge and Security Agreement, all Collateral
Investments held by the Trustee pursuant






                                                         7

to this Pledge and Security Agreement shall be held in the Collateral
Investments Account under exclusive dominion and control of the Trustee and for
the benefit of the Trustee and 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 Cash Collateral
Account and the Collateral Investments Account pending disbursement pursuant to
the terms hereof.

                  (d) Concurrently with the execution and delivery of this
Pledge and Security Agreement, the Pledgor is delivering to the Trustee
acknowledgement copies or stamped receipt copies of proper financing statements,
duly filed on or before the Closing Date in accordance with the Uniform
Commercial Code as in effect in the State of New York and the State of North
Carolina, covering the categories of Collateral described in this Pledge and
Security Agreement.

                  SECTION 7. Disbursements. The Trustee shall hold the assets in
the Cash Collateral Account and the Collateral Investments Account and release
the same, or a portion thereof, only as follows:

                  (a) At least five Business Days prior to the due date of any
         of the first six scheduled interest payments on the Notes, the Pledgor
         may, pursuant to written instructions executed by the Pledgor (an
         "Issuer Order"), direct the Trustee to release from the Cash Collateral
         Account, and if necessary liquidate Collateral Investments in the
         Collateral Investments Account indicated in the Issuer Order, and pay
         to the Holders of the Notes funds sufficient to provide for payment in
         full of such interest then due on the Notes. Upon receipt of an Issuer
         Order, the Trustee will take any action necessary to provide for the
         payment of the interest on the Notes in accordance with the payment
         provisions of the Indenture to the Holders of the Notes from (and to
         the extent of) funds available in the Cash Collateral Account and/or
         the Collateral Investments Account. Nothing in this Section 7 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 Cash Collateral Account and/or the Collateral
         Investments Account ("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 to
         release to the Pledgor or to another party at the direction of the
         Pledgor (a "Pledgor Designee") funds from the Cash Collateral Account,
         and if necessary liquidate Collateral Investments in the Collateral
         Investments Account indicated in the Issuer Order, in an amount less
         than or equal to the amount of Pledgor Funds applied






                                                         8

         to such interest payment. Upon receipt of an 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 funds in the
         Cash Collateral Account and/or the Collateral Investments Account.
         Concurrently with any release of funds to the Pledgor pursuant to this
         Section 7(b), the Pledgor shall deliver to the Trustee a certificate
         signed by an officer of the Pledgor stating that such release has been
         duly authorized by the Pledgor and will not contravene any provision of
         applicable law or the Certificate of Incorporation 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 and Security Agreement.

                  (c) If the Trustee receives, prior to 5:00 P.M. New York City
         time on the Termination Date, the Reorganization Officers' Certificate
         and the Opinion of Counsel with respect to the Reorganization, the
         Trustee shall immediately disburse funds and/or Cash Equivalents from
         the Cash Collateral Account and/or the Collateral Investments Account
         to the Pledgor, or at the written direction of the Pledgor, to a
         Pledgor Designee, by the close of business on such date such that the
         amount remaining in the Cash Collateral Account and the Collateral
         Investments Account equals (i) an amount sufficient to purchase U.S.
         Government Securities in such amount as will be sufficient upon receipt
         of scheduled interest and principal payments on such securities, in the
         opinion of a nationally recognized firm of independent public
         accountants selected by the Pledgor (which opinion shall be delivered
         to the Trustee), to provide for payment in full of the first six
         scheduled interest payments due on the Notes (including any interest
         that may be due in the event the Exchange Offer is not consummated or
         the Shelf Registration Statement is not declared effective as required
         by the Registration Rights Agreement) plus (ii) an amount sufficient to
         consummate a Special Repurchase Offer at a purchase price equal to 101%
         of the principal amount plus accrued interest to the repurchase date
         (assuming the Special Repurchase Offer remains open for the longest
         time permitted), in the event the FiberSouth Acquisition is not
         consummated by December 31, 1997; provided, however, that if the
         Reorganization Officer's Certificate and the Opinion of Counsel with
         respect to the Reorganization are received by the Trustee (i) on a day
         other than a Business Day or (ii) after 9:00 A.M. New York City time on
         any date, then, in either instance, the Trustee may disburse the
         proceeds by the close of business on the next Business Day.

                  (d) (i) On the Termination Date (or, in the event the Trustee
         receives a certificate signed by the President or any Vice President of
         the Pledgor stating that a Reorganization Officer's Certificate and
         Opinion of Counsel with respect to the






                                                         9

         Reorganization will not be delivered to the Trustee by the Termination
         Date, on the date five Business Days after the Trustee receives such
         certificate), if the conditions required for release of funds and/or
         Cash Equivalents as provided in clause (c) above have not been
         satisfied, the Trustee shall mail a notice by first class mail to each
         Holder's last address as it appears on the Security Register (as
         determined in the Indenture) stating that all of the outstanding Notes
         shall be redeemed within 10 days after the date of such notice (the
         "Special Redemption Date"), at 101% of the principal amount thereof
         plus accrued interest thereon to the Special Redemption Date (the
         "Special Redemption Price"), and shall state that the Notes must be
         surrendered to the Trustee in order to collect the Special Redemption
         Price.

                  (ii) On the Business Day prior to the Special Redemption Date,
         the Trustee shall release all Collateral to the Paying Agent. The Notes
         shall be redeemed as specified in the Indenture.

                  (e) If the Trustee receives, prior to 5:00 P.M. New York City
         time on the Termination Date, the FiberSouth Officers' Certificate and
         the Opinion of Counsel with respect to the FiberSouth Acquisition, the
         Trustee shall disburse from the Cash Collateral Account and/or the
         Collateral Investments Account to the Pledgor or, at the written
         direction of the Pledgor, to a Pledgor Designee, by the close of
         business on such date funds and/or proceeds from the sale of the Cash
         Equivalents held in the Collateral Investment Account other than the
         U.S. Government Securities referred to in clause (c)(i) above;
         provided, however, that if the FiberSouth Officer's Certificate and the
         Opinion of Counsel with respect thereto are received by the Trustee (i)
         on a day other than a Business Day or (ii) after 9:00 A.M. New York
         City time on such date, then, in either instance, the Trustee may
         disburse the proceeds by the close of business on the next Business
         Day. The Pledgor agrees to use, or to cause to be used, to the extent
         necessary, the disbursed proceeds to consummate the FiberSouth
         Acquisition on the date of such release.

                  (f) (i) On the Termination Date (or, in the event the Trustee
         receives a certificate signed by the President or any Vice President of
         the Pledgor stating that a FiberSouth Officer's Certificate and Opinion
         of Counsel with respect thereto will not be delivered to the Trustee by
         the Termination Date, on the date five Business Days after the Trustee
         receives such certificate), if the conditions required for release of
         funds and/or Cash Equivalents as provided in clause (e) above have not
         been satisfied, the Trustee shall mail a notice by first class mail to
         each Holder's last address as it appears in the Security Register (as
         defined in the Indenture) commencing the Special Repurchase Offer (and
         stating the date of purchase (the "Special Repurchase Offer Payment
         Date"), which shall be not less than 30 nor more than 60 days from the
         date such notice is mailed), at a purchase price of 101% of the
         principal amount thereof plus accrued interest thereon to the Special
         Repurchase Offer Payment Date (the






                                                        10

         "Special Repurchase Offer Price"), and shall state that the Notes must
         be surrendered to the Trustee in order to collect the Special
         Repurchase Offer Price.

                  (ii) On the Business Day prior to the Special Repurchase Offer
         Payment Date, the Trustee shall release to the Paying Agent Collateral
         sufficient, to pay the Special Repurchase Offer Price for all Notes
         validly tendered and not withdrawn. The Notes shall be purchased as
         specified in the Indenture.

                  (g) If the Pledgor is required to effect a Special Redemption
         contemplated by clause (d) or a Special Repurchase Offer contemplated
         by clause (f) above and for any reason the amount of Collateral to be
         released is insufficient to pay the aggregate Special Redemption Price
         and/or Special Repurchase Offer Price, as the case may be, the Pledgor
         and BTI jointly and severally agree to pay to the Paying Agent, on or
         prior to the Special Redemption Date or the Special Repurchase Offer
         Payment Date, as the case may be, the amount of funds necessary to
         permit the payment of the aggregate Special Redemption Price and/or
         Special Repurchase Offer Price, as the case may be.

                  (h) If at any time following disbursement by the Trustee in
         accordance with clauses (c) and (e) above, the principal of and
         earnings on the Collateral exceed 100% of the amount sufficient, in the
         written opinion of a nationally recognized firm of independent
         accountants selected by the Pledgor and delivered to the Trustee, to
         provide for payment in full of the first six scheduled interest
         payments due on the Notes (including any interest that may be due in
         the event the Exchange Offer is not consummated or the Shelf
         Registration Statement is not declared effective as required by the
         Registration Rights Agreement), the Pledgor may direct the Trustee to
         release any such overfunded amount to the Pledgor or to such other
         party as the Pledgor may direct in writing. Upon receipt of an Issuer
         Order, the Trustee shall pay over to the Pledgor or a Pledgor Designee,
         as the case may be, any such overfunded amount.

                  (i) Upon payment in full of the first six scheduled interest
         payments on the Notes in a timely manner, the security interest in the
         Collateral evidenced by this Pledge and Security Agreement will
         automatically terminate and be of no further force and effect and the
         Collateral shall promptly be paid over and transferred to the Pledgor.
         Furthermore, upon the release of any Collateral from the Cash
         Collateral Account and/or the Collateral Investments Account in
         accordance with the terms of this Pledge and Security Agreement,
         whether upon release of Collateral to Holders as payment of interest or
         otherwise, the security interest evidenced by this Pledge and Security
         Agreement in such released Collateral will automatically terminate and
         be of no further force and effect.


 




                                                        11

                  (j) At least five Business Days prior to the due date of any
         of the first six scheduled interest payments on the Notes, the Pledgor
         covenants to give the Trustee (by Issuer Order) notice as to whether
         payment of interest will be made pursuant to Section 7(a) or 7(b) and
         as to the respective amounts of interest that will be paid pursuant to
         Section 7(a) or 7(b). If no such notice is given, the Trustee will act
         pursuant to Section 7(a) as if it had received an Issuer Order pursuant
         thereto for the payment in full of the interest then due.

                  (k) The Trustee shall not be required to liquidate any
         Collateral Investment 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 14 hereof.

                  (l) Nothing contained in Section 1, Section 5, Section 6, this
         Section 7 or any other provision of this Pledge and Security Agreement
         shall (i) afford the Pledgor any right to issue entitlement orders with
         respect to any security entitlement to any of the 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 any of 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
         beneficial interest under this Pledge and Security Agreement in
         collateral pledged to and subject to the exclusive dominion and control
         (consistent with this Pledge and Security Agreement) of the Trustee in
         its capacity as such (and not as a securities intermediary). The
         Pledgor acknowledges, confirms and agrees 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 or
         financial intermediary.

                  SECTION 8. Representations and Warranties. The Pledgor and BTI
each hereby represents and warrants that:

                  (a) The execution and delivery by it of, and the performance
         by it of its obligations under, this Pledge and Security Agreement will
         not contravene any provision of applicable law or its Certificate of
         Incorporation or any material agreement or other material instrument
         binding upon it or any of its subsidiaries or any judgment, order or
         decree of any governmental body, agency or court having jurisdiction
         over its or any of its subsidiaries, or result in the creation or
         imposition of any Lien on any of its assets, except for the security
         interests granted under this Pledge and Security Agreement; no consent,
         approval, authorization or order of, or qualification with, any
         governmental body or agency is required (i) for the performance by it
         of its obligations under this Pledge and Security Agreement, (ii) for
         the pledge by the Pledgor of the Collateral pursuant to this Pledge and
         Security

 




                                                        12

         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
         (if any), for the exercise by the Trustee of the rights provided for in
         this Pledge and Security Agreement or the remedies in respect of the
         Collateral pursuant to this Pledge and Security 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 and Security
         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 and Security
         Agreement.

                  (c) This Pledge and Security Agreement has been duly
         authorized, validly executed and delivered by it and (assuming the due
         authorization and valid execution and delivery of this Pledge and
         Security Agreement by the Trustee and the Placement Agents and
         enforceability of this Pledge and Security Agreement against the
         Trustee and the Placement Agents in accordance with its terms)
         constitutes a valid and binding agreement of it, enforceable against it
         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 creditors' rights or remedies
         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 waivers of rights and defenses contained in
         Section 14(b), Section 17.11 and Section 17.16 hereof may be limited by
         applicable law.

                  (d) Upon the filing of financing statements, if any, required
         by the U.C.C. in the appropriate offices in the State of New York and
         the State of North Carolina, and the delivery to the Trustee of the
         Collateral, in accordance with this Pledge and Security Agreement, 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 first priority perfected
         security interest in such Collateral, enforceable as such against all
         creditors of the Pledgor (and any persons purporting to purchase any of
         the Collateral from the Pledgor), other than as permitted by the
         Indenture.

                  (e) There are no legal or governmental proceedings pending or,
         to the best of its knowledge, threatened to which it is a party or to
         which any of its properties is subject that would materially adversely
         affect the power or ability of it to perform its

 




                                                        13

         obligations under this Pledge and Security Agreement or to consummate
         the transactions contemplated hereby.

                  (f) The pledge of the Collateral pursuant to this Pledge and
         Security 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 exists.

                  SECTION 9. Further Assurances. The Pledgor and BTI will,
promptly upon request by the Trustee (which request the Trustee may submit at
the direction of the Holders of a majority in 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, 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 and
Security Agreement. The Pledgor and BTI each 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 and BTI jointly and severally agree to
promptly pay all reasonable costs incurred in connection with any of the
foregoing within 45 days of receipt of an invoice therefor. The Pledgor and BTI
each also agrees, whether or not requested by the Trustee, to take all actions
that are necessary to perfect or continue the perfection of, or to protect the
first priority of, the Trustee's security interest in and to the Collateral,
including the filing of all necessary financing and continuation statements, 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).

                  SECTION 10. Covenants. The Pledgor and BTI each covenants and
agrees with the Trustee and the Holders of the Notes that from and after the
date of this Pledge and Security Agreement until the earlier of payment in full
in cash of (x) each of the first six scheduled interest payments due on the
Notes under the terms of the Indenture or (y) all obligations due and owing
under the Indenture and the Notes in the event such obligations become due and
payable prior to the payment of the first six scheduled interest payments on the
Notes:

                  (a) that (i) it will not (and will not purport to) sell or
         otherwise dispose of, or grant any option or warrant with respect to,
         any of the Collateral or its beneficial interest therein, and (ii) it
         will not create or permit to exist any Lien upon or other

 




                                                        14

         adverse interest in or with respect to its beneficial interest in any
         of the Collateral (except for the security interests granted under this
         Pledge and Security Agreement); 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 its beneficial interest in 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 such
         beneficial interest.

                  SECTION 11. Power of Attorney. In addition to all of the
powers granted to the Trustee pursuant to the Indenture, the Pledgor and BTI
each hereby appoints and constitutes the Trustee as its 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 6 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 11 shall include, without limitation, the authority to
endorse and negotiate any checks or other instruments representing proceeds of
Collateral, 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 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 and Security Agreement. This power of
attorney is coupled with an interest and is irrevocable by the Pledgor.

                  SECTION 12. No Assumption of Duties; Reasonable Care. The
rights and powers granted to the Trustee hereunder are being granted in order to
establish, preserve and protect the 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 expressly 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

 




                                                        15

substantially equal to that which the Trustee accords similar property held by
the Trustee for its own account, 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.

                  SECTION 13. Indemnity. The Pledgor shall indemnify, hold
harmless and defend the Trustee and its directors, officers, agents and
employees, 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 and Security 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.

                  SECTION 14. 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 and Security Agreement as an "Event of
Default") shall have occurred and be continuing:

                  (a) The Trustee and the Holders of the Notes shall have, in
         addition to all other rights given by law or by this Pledge and
         Security Agreement or the Indenture, all of the rights and remedies
         with respect to the Collateral of a secured party under the U.C.C. in
         effect in the State of New York 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 principal amount of the Notes
         then outstanding, shall, 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 as the Trustee 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 or is or becomes of a type sold on a
         recognized market, 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

 




                                                        16

         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 fees and 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. In no
         event shall the Trustee be liable for any loss or diminution in value
         of the Collateral sold or offered for sale in accordance with this
         Section 14.

                  (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 14 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 14 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 14
         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 15. 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
and Security Agreement, (b) the custody or preservation of, or the sale of,
collection from, or other 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 16. 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:

                  (a) any lack of validity or enforceability of the Indenture or
         any other agreement or instrument relating thereto;

                  (b) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Obligations, or any other
         amendment or waiver of or any consent to any departure from the
         Indenture;

 




                                                        17


                  (c) any exchange, surrender, release or non-perfection of any
         Liens on any other collateral for all or any of the Obligations; or

                  (d) to the extent permitted by applicable law, any other
         circumstance which might otherwise constitute a defense available to,
         or a discharge of, the Pledgor in respect of the Obligations or of this
         Pledge and Security Agreement.

                  SECTION 17.  Miscellaneous Provisions.

                  17.1. Notices. Any notice or communication shall be

                           Attention:  Corporate Trust Administration


                  17.2. No Adverse Interpretation of Other Agreements. This
Pledge and Security Agreement may not be used to interpret another pledge,
security or debt agreement of the Pledgor or any subsidiary thereof. No such
pledge, security or debt agreement (other than the Indenture) may be used to
interpret this Pledge and Security Agreement.

                  17.3. Severability. The provisions of this Pledge and Security
Agreement are severable, and if any clause or provision shall be held invalid,
illegal or unenforceable in

 




                                                        18

whole or in part in any jurisdiction, then such invalidity or unenforceability
shall affect in that jurisdiction only such clause or provision, or part
thereof, and shall not in any manner affect such clause or provision in any
other jurisdiction or any other clause or provision of this Pledge and Security
Agreement in any jurisdiction.

                  17.4. Headings. The headings in this Pledge and Security
Agreement have been inserted for convenience of reference only, are not to be
considered a part hereof and shall in no way modify or restrict any of the terms
or provisions hereof.

                  17.5. Counterpart Originals. This Pledge and Security
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 and Security Agreement. Nothing in
this Pledge and Security 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 and Security Agreement.

                  17.7. Amendments, Waivers and Consents. Any amendment or
waiver of any provision of this Pledge and Security Agreement and any consent to
any departure by the Pledgor from any provision of this Pledge and Security
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. Consistent with the foregoing, this Pledge and Security
Agreement may be amended, its provisions may be waived and departures from its
provisions may be consented to by action of the Pledgor and the Trustee and (if
applicable) the Holders of the Notes, all as provided in the Indenture, and no
such amendment, waiver or consent shall require any action or approval of the
Placement Agents. 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. To the extent a term or
provision of this Pledge and Security Agreement conflicts with the Indenture,
the Indenture shall control with respect to the subject matter of such term or
provision. The Trustee shall be entitled to all its rights and privileges and
immunities under the Indenture in performing hereunder.

 




                                                        19

Acceptance of or acquiescence in a course of performance rendered under this
Pledge and Security Agreement shall not be relevant to determine the meaning of
this Pledge and Security 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 and Security Agreement shall create a continuing security interest in and
to the Collateral and shall, except as otherwise provided in the Indenture or in
this Pledge and Security Agreement, remain in full force and effect until the
payment in full in cash of the Obligations. This Pledge and Security 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.

                  (b) This Pledge and Security Agreement shall terminate (except
as to surviving rights of indemnity) upon the payment in full in cash of the
Obligations. At such time, the Trustee shall, pursuant to an Issuer Order,
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 and Security 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.

                  (c) Notwithstanding anything to the contrary contained in or
implied by this Pledge and Security Agreement, in the event the Reorganization
and FiberSouth Acquisition are consummated on the date hereof (i) BTI shall have
no liability or obligation whatsoever, to any person or entity, under or
pursuant to this Pledge and Security Agreement and (ii) neither the Trustee nor
any other person or entity shall have any claim or cause of action of any nature
whatsoever against BTI under or pursuant to this Pledge and Security Agreement.

                  17.10. Survival Provisions. All representations, warranties
and covenants of the Pledgor and BTI contained herein shall survive the
execution and delivery of this Pledge and Security Agreement, and shall
terminate only upon the termination of this Pledge and Security Agreement. The
obligations of the Pledgor under Sections 13 and 15 hereof shall survive the
termination of this 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 terms 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 and Security 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 reasonably 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.

                  (b) The Pledgor acknowledges that the rights and
responsibilities of the Trustee under this Pledge and Security Agreement with
respect to any action taken by the Trustee or the 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 and Security
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.  Intentionally Omitted.

                  17.14. Final Expression. This Pledge and Security 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 and
Security Agreement and is intended as a complete and exclusive statement of the
terms and conditions thereof.

                  17.15. Rights of Holders of the Notes. No Holder of Notes
shall have any independent rights hereunder other than those rights granted to
individual Holders of the Notes pursuant to Section 6.07 of the Indenture;
provided that nothing in this subsection shall limit any rights granted to the
Trustee under the Notes or the Indenture.

                  17.16.  GOVERNING LAW; SUBMISSION TO JURISDICTION; WAIVER
OF JURY TRIAL; WAIVER OF DAMAGES.  (a)  THIS PLEDGE AND SECURITY

 




                                                        21

TO THE EXTENT PERMITTED BY APPLICABLE LAW, TO PROCEED AGAINST THE PLEDGOR OR THE
COLLATERAL IN A COURT IN ANY LOCATION REASONABLY SELECTED IN GOOD FAITH (AND
HAVING PERSONAL OR IN REM JURISDICTION OVER THE PLEDGOR OR THE COLLATERAL, AS
THE CASE MAY BE) TO ENABLE THE TRUSTEE TO REALIZE ON SUCH COLLATERAL, OR TO
ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF THE TRUSTEE. THE
PLEDGOR AGREES THAT IT WILL NOT ASSERT ANY COUNTERCLAIMS, SETOFFS OR CROSSCLAIMS
IN ANY PROCEEDING BROUGHT BY THE TRUSTEE TO REALIZE ON SUCH PROPERTY OR TO
ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE TRUSTEE, EXCEPT FOR SUCH
COUNTERCLAIMS, SETOFFS OR CROSSCLAIMS WHICH, IF NOT ASSERTED IN ANY SUCH
PROCEEDING, COULD NOT OTHERWISE BE BROUGHT OR ASSERTED. THE PLEDGOR WAIVES ANY
OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN THE CITY OF NEW YORK

INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON

CONNECTION THEREWITH, UNLESS IT IS DETERMINED BY A FINAL AND NONAPPEALABLE
JUDGMENT OF A COURT THAT IS BINDING ON THE TRUSTEE OR SUCH HOLDER OF NOTES, AS
THE CASE MAY BE, THAT SUCH LOSSES WERE THE RESULT OF ACTS OR OMISSIONS ON THE
PART OF THE TRUSTEE OR SUCH HOLDERS OF NOTES, AS THE CASE MAY BE, CONSTITUTING
BAD FAITH, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

                  (e) TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE PLEDGOR
WAIVES THE POSTING OF ANY BOND OTHERWISE REQUIRED OF THE TRUSTEE OR ANY HOLDER
OF NOTES IN CONNECTION WITH ANY JUDICIAL PROCESS OR PROCEEDING TO ENFORCE ANY
JUDGMENT OR OTHER COURT ORDER PERTAINING TO THIS PLEDGE AND SECURITY AGREEMENT

                           Form of Opinion of Counsel

                  I. Form of opinion to be delivered in connection with the
Reorganization

                  (A) the Reorganization has been duly and validly authorized by
the Pledgor and BTI, and all corporate action on the part of the Pledgor and BTI
and the Pledgor's and BTI's shareholders necessary to approve the Reorganization
has been accomplished;

                  (B) no consent, approval, authorization or order of, or
qualification with, any United States or state governmental body, agency or
court having jurisdiction over the Pledgor or BTI or any of its subsidiaries is
required for the consummation of the Reorganization by the Pledgor or BTI
pursuant to the applicable transaction documents, except such as may be required
under the federal and state telecommunications laws; and

                  (C) the execution and delivery by the Pledgor and BTI of, and
the performance by the Pledgor and BTI of its obligations under the applicable
