             the location of any Collateral if such change would cause the

             filings of financing or continuation statements under the UCC)
             that from time to time may be necessary, or that the
             Administrative Agent may reasonably request, in order to
             create, preserve, upgrade in rank (to the extent required
             hereby), perfect, confirm or validate the Security Interests
             or to enable the Administrative Agent and the Lenders to
             obtain the full benefits of this Agreement, or to enable the
             Administrative Agent to exercise and enforce any of its
             rights, powers and remedies hereunder with respect to any of
             the Collateral (other than any filings with the United States
             Patent and Trademark Office or the United States Copyright
             Office).  Prior to the irrevocable payment in full of the
             Secured Obligations, each Grantor hereby authorizes the
             Administrative Agent, upon the failure of such Grantor to so
             do within three Business Days after receipt of notice from the

             statements, financing statement amendments or continuation
             statements without such Grantor's signature appearing thereon. 
             Each Grantor agrees that a carbon, photographic, photostatic
             or other reproduction of this Agreement or of a financing
             statement is sufficient as a financing statement.  Each
             Grantor shall pay the costs of, or incidental to, any
             recording or filing of the Financing Statements and any other
             financing statements, financing statement amendments or
             continuation statements concerning the Collateral.

                  (iv)  If any Collateral exceeding in value $500,000 in
             the aggregate is at any time in the possession or control of
             any warehouseman, bailee (other than a carrier transporting
             Inventory to a purchaser in the ordinary course of business),
             or any Grantor's agents or processors, such Grantor shall

             for the ratable benefit of itself and the Lenders, to be named
             as loss payee on each insurance policy covering risks relating
             to any of its Inventory, Fixtures and Equipment, as reasonably
             requested by the Administrative Agent.  Each Grantor will
             deliver to the Administrative Agent, upon request of the

             for appropriate certifications that the requirements of this
             Section 4(a)(v) have been satisfied, to be made to the

             Administrative Agent to enforce the provisions of this
             Agreement.

                  (vii)  Each Grantor will comply in all material respects

             without limitation, claims for labor, materials and supplies)
             against or with respect to the Collateral, except that no such
             charge need be paid if (A) the validity thereof is being
             contested in good faith by appropriate proceedings, (B) such
             proceedings do not involve any danger of the sale, forfeiture
             or loss of or creation of a Lien on any of the Collateral or
             any interest therein and (C) such charge is adequately
             reserved against on such Grantor's books in accordance with

                  otherwise) or otherwise dispose of any of the Collateral,
                  except as permitted by the Amended and Restated Credit
                  Agreement; or

                       (B)  create or suffer to exist any Lien or other

             any Event of Default, upon request of the Administrative Agent
             or the Required Lenders, each Grantor will promptly notify
             (and each Grantor hereby authorizes the Administrative Agent
             so to notify) each Account Debtor in respect of any Account
             that such Account has been assigned to the Administrative
             Agent hereunder and that any payments due or to become due in
             respect of such Account are to be made directly to the
             Administrative Agent or its designee.

                  (iii)  Each Grantor will perform and comply in all
             material respects with all of its obligations in respect of
             Accounts and General Intangibles and the exercise by the

             waive any material provision of any agreement giving rise to
             an Account in any manner which could reasonably be expected to

             Agent a copy of each material demand, notice or document
             received by it relating in any way to any agreement giving
             rise to an Account.

                  (v)  Other than in the ordinary course of business as
             generally conducted by such Grantor over a period of time, no
             Grantor will grant any extension of the time of payment of any
             of the Accounts to any one Account Debtor with an aggregate
             face amount in excess of $25,000 or compromise, compound or

             (d)  Equipment, Etc.  Each Grantor will maintain each item of

             (e)  Intellectual Property.

                  (i)  Each Grantor shall notify the Administrative Agent
             promptly (A) of its acquisition after the Closing Date of any
             Patent, Patent License, Trademark or Trademark License and (B)
             if it knows, or has reason to know of any adverse
             determination or development (including, without limitation,
             the institution of, or any such determination or development
             in, any proceeding in the United States Patent and Trademark
             Office or any court) regarding such Grantor's ownership of any
             Patent or Trademark, its right to register the same, or to
             keep and maintain the same.  In the event that any Patent,
             Patent License, Trademark or Trademark License is infringed,
             misappropriated or diluted by a third party, each Grantor
             shall notify the Administrative Agent promptly after it learns
             thereof and shall, unless such Grantor and the Administrative
             Agent shall jointly determine that any such action would be of
             immaterial economic value, promptly sue for infringement,
             misappropriation or dilution and to recover any and all
             damages for such infringement, misappropriation or dilution,
             and take such other actions as may be appropriate under the
             circumstances to protect such Patent, Patent License,
             Trademark or Trademark License.  In no event shall any
             Grantor, either itself or through any agent, employee or
             licensee, file an application for the registration of any
             Patent or Trademark with the United States Patent and
             Trademark Office or any similar office or agency in any other
             country or any political subdivision thereof, unless
             simultaneously therewith it informs the Administrative Agent,
             and, upon issuance of such Patent or Trademark, executes and
             delivers any and all agreements, instruments, documents and
             papers the Administrative Agent may reasonably request to
             evidence the Security Interests in such Patent or Trademark
             and the goodwill and general intangibles of such Grantor
             relating thereto or represented thereby.  Each Grantor hereby
             constitutes the Administrative Agent its attorney-in-fact to
             execute and file all such writings for the foregoing purposes,
             all acts of such attorney being hereby ratified and confirmed,
             and such power, being coupled with an interest, shall be
             irrevocable until the Commitments have terminated and the
             Secured Obligations are paid in full.

                  (ii)  Each Grantor shall:  (A) preserve and maintain in
             all material respects rights in the Intellectual Property; and
             (B) upon and after the occurrence of an Event of Default, use
             its best efforts to obtain any consents, waivers or agreements
             necessary to enable Administrative Agent to exercise its
             remedies with respect to the Intellectual Property.  No
             Grantor shall abandon any right to file a Copyright, Patent or
             Trademark application that is material to the business of such
             Grantor nor shall any Grantor abandon any such pending
             Copyright, Patent or Trademark application, or Copyright,
             Copyright License, Patent, Patent License, Trademark or
             Trademark License without the prior written consent of
             Administrative Agent.

                  (iii)  Each Grantor hereby assigns, transfers and conveys
             to Administrative Agent, effective upon the occurrence and
             during the continuance of any Event of Default, the
             nonexclusive right and license to use all Intellectual
             Property owned or used by such Grantor, together with any
             goodwill associated therewith, all to the extent necessary to
             enable Administrative Agent to realize on the Collateral
             (including, without limitation, completing production of,
             advertising for sale and selling the Collateral) and any
             successor or assign to enjoy the benefits of the Collateral. 
             This right and license shall inure to the benefit of all
             successors, assigns and transferees of Administrative Agent
             and its successors, assigns and transferees, whether by
             voluntary conveyance, operation of law, assignment, transfer,
             foreclosure, deed in lieu of foreclosure or otherwise.  Such
             right and license is granted free of charge, without
             requirement that any monetary payment whatsoever be made to
             any Grantor by Administrative Agent.

             (f)  Indemnification.  Each Grantor agrees to pay, and to save
the Administrative Agent and the Lenders harmless from, any and all
liabilities, costs and expenses (including, without limitation, legal
fees and expenses) (i) with respect to, or resulting from, any and all
excise, sales or other taxes which may be payable or determined to be
payable with respect to any of the Collateral, (ii) with respect to, or
resulting from, complying with any Applicable Law applicable to any of
the Collateral or (iii) in connection with any of the transactions
contemplated by this Agreement (except to the extent any such
liabilities, costs and expenses result from the gross negligence or
willful misconduct of the Administrative Agent or Lenders).  In any
suit, proceeding or action brought by the Administrative Agent under any
Account for any sum owing thereunder, or to enforce any provisions of
any Account, each Grantor will save, indemnify and keep the
Administrative Agent and the Lenders harmless from and against all
expense, loss or damage suffered by reason of any defense, setoff,
counterclaim, recoupment or reduction or liability whatsoever of the
Account Debtor or any other obligor thereunder, arising out of a breach
by such Grantor of any obligation thereunder or arising out of any other
agreement, indebtedness or liability at any time owing to or in favor of
such Account Debtor or obligor or its successors from such Grantor
(except to the extent any such expense, loss or damage results from the
gross negligence or willful misconduct of the Administrative Agent or
Lenders).  The obligations of each Grantor under this Section 4(f) shall
survive the termination of the other provisions of this Agreement.

             Section 5.  Reporting and Recordkeeping.  Each Grantor
respectively covenants and agrees with the Administrative Agent and the
Lenders that from and after the date of this Agreement and until the
Commitments have terminated and all Secured Obligations have been fully
satisfied:

and maintain at its own cost and expense complete and accurate records
of the Collateral, including, without limitation, a record of all
payments received and all credits granted with respect to the Collateral
and all other dealings with the Collateral.  All chattel paper given to
such Grantor with respect to any Accounts will be marked with the
following legend:  "This writing and the obligations evidenced or
secured hereby are subject to the security interest of First Union
National Bank of North Carolina, as Administrative Agent".  For the
Administrative Agent's and the Lenders' further security, such Grantor
agrees that upon the occurrence and during the continuation of any Event
of Default, such Grantor shall deliver and turn over any such books and
records directly to the Administrative Agent or its designee.  Such
Grantor shall permit any representative of the Administrative Agent to
inspect such books and records in accordance with Section 8.11 of the
Amended and Restated Credit Agreement and will provide photocopies
thereof to the Administrative Agent upon its reasonable request.

             (b)  Certain Provisions Regarding Maintenance of Records and
Reporting Re: Accounts.

                  (i)  In the event any amounts due and owing in excess of
             $250,000 are in dispute between any Account Debtor and such
             Grantor, such Grantor shall provide the Administrative Agent
             with written notice thereof promptly after such Grantor's
             learning thereof, explaining in detail the reason for the
             dispute, all claims related thereto and the amount in
             controversy; provided, that a report of such items provided
             within ten (10) days after the end of each fiscal quarter of
             ACC shall be deemed to be prompt delivery of such notice.

                  (ii)  Such Grantor will promptly notify the
             Administrative Agent in writing if any Account arises out of
             a contract with the United States of America, or any
             department, agency, subdivision or instrumentality thereof, or
             of any state (or department, agency, subdivision or
             instrumentality thereof) where such state has a state
             assignment of claims act or other law comparable to the
             Federal Assignment of Claims Act, and will take any action
             required or requested by the Administrative Agent or give
             notice of the Administrative Agent's Security Interest in such
             Accounts under the provisions of the Federal Assignment of
             Claims Act or any comparable law or act enacted by any state
             or local governmental authority.

             (c)  Further Identification of Collateral.  Such Grantor will,
if so requested by the Administrative Agent, furnish to the
Administrative Agent statements and schedules further identifying and
describing the Collateral and such other reports in connection with the
Collateral as the Administrative Agent may reasonably request, all in
reasonable detail.

             (d)  Notices.  In addition to the notices required by
Section 5(b) hereof, such Grantor will advise the Administrative Agent
promptly, in reasonable detail, (i) of any material Lien or claim made
or asserted against any of the Collateral, (ii) of any material adverse
change in the composition of the Collateral, and (iii) of the occurrence
of any other event which could have a material adverse effect on the
Collateral or on the validity, perfection or priority of the Security
Interests.

             SECTION 6.  Collateral Account.

             (a)  There is hereby established with the Administrative Agent
a Collateral Account in the name and under the exclusive dominion and
control of the Administrative Agent.  There shall be deposited from time
to time into such account the cash proceeds of the Collateral required
to be delivered to the Administrative Agent pursuant to Section 6(b) or
any other provision of this Agreement.  Any income received by the
Administrative Agent with respect to the balance from time to time
standing to the credit of the Collateral Account, including any interest
or capital gains on investments of amounts on deposit in the Collateral
Account, shall remain, or be deposited, in the Collateral Account
together with any investments from time to time made pursuant to
subsection (c) of this Section 6, shall vest in the Administrative
Agent, shall constitute part of the Collateral hereunder and shall not
constitute payment of the Secured Obligations until applied thereto as
hereinafter provided.

             (b)  Upon the occurrence and during the continuance of an
Event of Default, if requested by the Administrative Agent, each Grantor
shall instruct all Account Debtors and other Persons obligated in
respect of all Accounts to make all payments in respect of the Accounts
either (i) directly to the Administrative Agent (by instructing that
such payments be remitted to a post office box which shall be in the
name and under the exclusive dominion and control of the Administrative
Agent) or (ii) to one or more other banks in any state in the United
States (by instructing that such payments be remitted to a post office
box which shall be in the name and under the exclusive dominion and
control of such bank) under a Lockbox Letter substantially in the form
of Annex I hereto duly executed by each Grantor and such bank or under
other arrangements, in form and substance satisfactory to the
Administrative Agent, pursuant to which such Grantor shall have
irrevocably instructed such other bank (and such other bank shall have
agreed) to remit all proceeds of such payments directly to the
Administrative Agent for deposit into the Collateral Account or as the
Administrative Agent may otherwise instruct such bank, and thereafter if
the proceeds of any Collateral shall be received by such Grantor, such
Grantor will promptly deposit such proceeds into the Collateral Account
and until so deposited, all such proceeds shall be held in trust by such
Grantor for and as the property of the Administrative Agent, for the
benefit of itself and the Lenders and shall not be commingled with any
other funds or property of such Grantor.  At any time after the
occurrence and during the continuance of an Event of Default, the
Administrative Agent may itself so instruct such Grantor's Account
Debtors and each Grantor hereby constitutes and appoints the
Administrative Agent (and the president, any vice president or any
assistant vice president of the Administrative Agent from time to time)
as its attorney-in-fact with full power and authority to so instruct
such Grantor's Account Debtors.  All such payments made to the
Administrative Agent shall be deposited in the Collateral Account.

             (c)  The balance from time to time standing to the credit of
the Collateral Account shall, except upon the occurrence and
continuation of an Event of Default, be distributed to the Grantors upon
the order of the Grantors.  If immediately available cash on deposit in
the Collateral Account is not sufficient to make any distribution to the
Grantors referred to in the previous sentence of this Section 6(c), the
Administrative Agent shall liquidate as promptly as practicable such
investments as required to obtain sufficient cash to make such
distribution and, notwithstanding any other provision of this Section 6,
such distribution shall not be made until such liquidation has taken
place.  Upon the occurrence and continuation of an Event of Default, the
Administrative Agent shall, if so instructed by the Required Lenders,
apply or cause to be applied (subject to collection) any or all of the
balance from time to time standing to the credit of the Collateral
Account in the manner specified in Section 10. 

             (d)  Amounts on deposit in the Collateral Account shall be
invested and reinvested from time to time in Permitted Investments as
the Grantors shall determine, which investments shall be held in the
name and be under the control of the Administrative Agent; provided,
that if an Event of Default has occurred and is continuing, the
Administrative Agent may and, if instructed by the Required Lenders,
shall liquidate any such investments and apply or cause to be applied
the proceeds thereof to the payment of the Secured Obligations in the
manner specified in Section 10 hereof; and provided further, that
(i) each such investment shall mature within thirty (30) days after it
is acquired by the Administrative Agent and (ii) in order to provide the
Administrative Agent, for the ratable benefit of itself and the Lenders,
with a perfected security interest therein, each such investment shall
be either:

                  (A)  evidenced by negotiable certificates or Instruments,
             or if non-negotiable then issued in the name of the
             Administrative Agent, which (together with any appropriate
             instruments of transfer) are delivered to, and held by, the
             Administrative Agent or any agent thereof (which shall not be
             any of the Grantors or any of their Affiliates) in the State
             of North Carolina; or

                  (B)  in book-entry form and issued by the United States
             and subject to pledge under applicable state law and Treasury
             regulations and as to which (in the opinion of counsel to the
             Administrative Agent) appropriate measures shall have been
             taken for perfection of the Security Interests.

             (e)  Upon the occurrence of any Event of Default, the
Administrative Agent is authorized at any time and from time to time,
and during the continuance thereof, without notice to the Grantors, to
set off, appropriate and apply any and all amounts on deposit in the
Collateral Account, and the proceeds thereof, against all Secured
Obligations.

             SECTION 7.  General Authority.  

             (a)  Each Grantor hereby irrevocably appoints the
Administrative Agent its true and lawful attorney, with full power of
substitution, in the name of such Grantor, the Administrative Agent, the
Lenders or otherwise, for the sole use and benefit of the Administrative
Agent and the Lenders, but at such Grantor's expense, to exercise, at
any time from time to time all or any of the following powers:

                  (i)  to file the Financing Statements and any financing
             statements, financing statement amendments and continuation
             statements referred to in Sections 4(a)(i), 4(a)(ii), and
             4(a)(iii) hereof,

                  (ii) to demand, sue for, collect, receive and give
             acquittance for any and all monies due or to become due with
             respect to any Collateral or by virtue thereof,

                  (iii)  to settle, compromise, compound, prosecute or
             defend any action or proceeding with respect to any
             Collateral,

                  (iv)  to sell, transfer, assign or otherwise deal in or
             with the Collateral and the Proceeds thereof, as fully and
             effectually as if the Administrative Agent were the absolute
             owner thereof, and

                  (v)  to extend the time of payment and to make any
             allowance and other adjustments with reference to the
             Collateral;

provided that the Administrative Agent shall not take any of the actions
described in this Section 7 except those described in clause (i) above
unless an Event of Default shall have occurred and be continuing and the
Administrative Agent shall give such Grantor not less than ten
(10) days' prior written notice of the time and place of any sale or
other intended disposition of any of the Collateral, except any
Collateral which is perishable or threatens to decline speedily in value
or is of a type customarily sold on a recognized market.  Each Grantor
agrees that any such notice constitutes "reasonable notification" within
the meaning of Section 9504(3) of the UCC (to the extent such Section is
applicable).

             (b)  Each Grantor hereby ratifies all that said attorney shall
lawfully do or cause to be done by virtue hereof.  This power of
attorney is a power coupled with an interest and shall be irrevocable.

             (c)  Each Grantor also authorizes the Administrative Agent at
any time and from time to time, to execute, in connection with the sale
provided for in Section 8 hereof, any endorsements, assignments or other
instruments of conveyance or transfer with respect to the Collateral.

             SECTION 8.  Remedies Upon Event of Default.

             (a)  If any Event of Default has occurred and is continuing,
the Administrative Agent may exercise on behalf of itself and the
Lenders all rights of a secured party under the UCC (whether or not in
effect in the jurisdiction where such rights are exercised) and, in
addition, the Administrative Agent may (i) withdraw all cash, if any, in
the Collateral Account and investments made with amounts on deposit in
the Collateral Account, and apply such monies, investments and other
cash, if any, then held by it as Collateral as specified in Section 10
hereof and (ii) if there shall be no such monies, investments or cash or
if such monies, investments or cash shall be insufficient to pay all the
Secured Obligations in full, sell the Collateral or any part thereof at
public or private sale, for cash, upon credit or for future delivery,
and at such price or prices as the Administrative Agent may deem
satisfactory.  The Administrative Agent or any Lender may be the
purchaser of any or all of the Collateral so sold at any public sale
(or, if the Collateral is of a type customarily sold in a recognized
market or is of a type which is the subject of widely distributed
standard price quotations or if otherwise permitted under applicable
law, at any private sale) and thereafter hold the same, absolutely, free
from any right or claim of whatsoever kind.  Each Grantor will execute
and deliver such documents and take such other action as the
Administrative Agent deems reasonably necessary or advisable in order
that any such sale may be made in compliance with law.  Upon any such
sale the Administrative Agent shall have the right to deliver, assign
and transfer to the purchaser thereof the Collateral so sold (without
warranty).  Each purchaser at any such sale shall hold the Collateral so
sold to it absolutely, free from any claim or right of whatsoever kind,
including any equity or right of redemption of any Grantor.  To the
extent permitted by law, each Grantor hereby specifically waives all
rights of redemption, stay or appraisal which it has or may have under
any law now existing or hereafter adopted.  The notice of such sale
shall be given to the applicable Grantor ten (10) days prior to such
sale and (A) in case of a public sale, state the time and place fixed
for such sale, and (B) in the case of a private sale, state the day
after which sale may be consummated.  Any such public sale shall be held
at such time or times within ordinary business hours and at such place
or places as the Administrative Agent may fix in the notice of such
sale.  At any such sale the Collateral may be sold in one lot as an
entirety or in separate parcels, as the Administrative Agent may
determine.  The Administrative Agent shall not be obligated to make any
such sale pursuant to any such notice.  The Administrative Agent may,
without notice or publication, adjourn any public or private sale or
cause the same to be adjourned from time to time by announcement at the
time and place fixed for the sale, and such sale may be made at any time
or place to which the same may be so adjourned.  In case of any sale of
all or any part of the Collateral on credit or for future delivery, the
Collateral so sold may be retained by the Administrative Agent until the
selling price is paid by the purchaser thereof, but the Administrative
Agent shall not incur any liability in case of the failure of such
purchaser to take up and pay for the Collateral so sold and, in case of
any such failure, such Collateral may again be sold upon like notice. 
The Administrative Agent, instead of exercising the power of sale herein
conferred upon it, may proceed by a suit or suits at law or in equity to
foreclose the Security Interests and sell the Collateral, or any portion
thereof, under a judgment or decree of a court or courts of competent
jurisdiction.  The Grantors shall remain liable for any deficiency.

             (b)  For the purpose of enforcing any and all rights and
remedies under this Agreement, the Administrative Agent may if an Event
of Default has occurred and is continuing (i) require each  Grantor to,
and each Grantor agrees that it will, at its expense and upon the
request of the Administrative Agent, forthwith assemble all or any part
of the Collateral as directed by the Administrative Agent and make it
available at a place designated by the Administrative Agent which is, in
the Administrative Agent's opinion, reasonably convenient to the
Administrative Agent and such Grantor, whether at the premises of such
Grantor or otherwise, (ii) to the extent permitted by applicable law,
enter, with or without process of law and without breach of the peace,
any premise where any of the Collateral is or may be located and,
without charge or liability to the Administrative Agent, seize and
remove such Collateral from such premises, (iii) have access to and use
such Grantor's books and records relating to the Collateral and (iv)
prior to the disposition of the Collateral, store or transfer such
Collateral without charge in or by means of any storage or
transportation facility owned or leased by such Grantor, process, repair
or recondition such Collateral or otherwise prepare it for disposition
in any manner and to the extent the Administrative Agent deems
appropriate and, in connection with such preparation and disposition,
use without charge any Trademark, trade name, Copyright, Patent or
technical process used by such Grantor.

             (c)  Without limiting the generality of the foregoing, if any
Event of Default has occurred and is continuing,

                  (i)  the Administrative Agent may license, or sublicense,
             whether general, special or otherwise, and whether on an
             exclusive or non-exclusive basis, any Patents or Trademarks
             included in the Collateral throughout the world for such term
             or terms, on such conditions and in such manner as the
             Administrative Agent shall in its sole discretion determine;

                  (ii)  the Administrative Agent may (without assuming any
             obligations or liability thereunder), at any time and from
             time to time, enforce (and shall have the exclusive right to
             enforce) against any licensee or sublicensee all rights and
             remedies of any Grantor in, to and under any Patent Licenses
             or Trademark Licenses and take or refrain from taking any
             action under any thereof, provided, that no such actions shall
             result in the failure of such Patent Licenses or Trademark
             Licenses to remain in compliance with all Applicable Law, and
             each Grantor hereby releases the Administrative Agent and each
             of the Lenders from and against any claims arising out of, any
             lawful action so taken or omitted to be taken with respect
             thereto except with respect to the gross negligence or willful
             misconduct of the Administrative Agent or the Lenders; and

                  (iii)  upon request by the Administrative Agent, each
             Grantor will execute and deliver to the Administrative Agent
             a power of attorney, in form and substance satisfactory to the
             Administrative Agent, for the implementation of any lease,
             assignment, license, sublicense, grant or option, sale or
             other disposition of a Patent or Trademark.  In the event of
             any such disposition pursuant to this Section, each Grantor
             shall supply its know-how and expertise relating to the
             manufacture and sale of the products bearing Trademarks or the
             products or services made or rendered in connection with
             Patents, and its customer lists and other records relating to
             such Patents or Trademarks and to the distribution of said
             products, to the Administrative Agent.

             SECTION 9.  Limitation on Duty of Administrative Agent in
Respect of Collateral.  Beyond reasonable care in the custody thereof,
the Administrative Agent shall have no duty as to any Collateral in its
possession or control or in the possession or control of any agent or
bailee or any income thereon or as to the preservation of rights against
prior parties or any other rights pertaining thereto.  The
Administrative Agent shall be deemed to have exercised reasonable care
in the custody of the Collateral in its possession if the Collateral is
accorded treatment substantially equal to that which it accords its own
property, and the Administrative Agent shall not be liable or
responsible for any loss or damage to any of the Collateral, or for any
diminution in the value thereof, by reason of the act or omission of any
warehouseman, carrier, forwarding agency, consignee or other agent or
bailee selected by the Administrative Agent in good faith.

             SECTION 10.  Application of Proceeds.  Upon the occurrence and
during the continuance of an Event of Default, the proceeds of any sale
of, or other realization upon, all or any part of the Collateral shall
be applied by the Administrative Agent as follows:

                  first, to payment of the out-of-pocket expenses of such
             sale or other realization, including all reasonable
             out-of-pocket expenses, liabilities and advances incurred or
             made by the Administrative Agent in connection therewith, and
             any other unreimbursed expenses for which the Administrative
             Agent or any Lender is to be reimbursed pursuant to
             Section 14.2 of the Amended and Restated Credit Agreement, or
             Section 4(f) or 13 hereof or any corresponding provision of
             any of the other Loan Documents;

                  second, to payment of any fees owing to the 
             Administrative Agent or any Lender under the Amended and
             Restated Credit Agreement in accordance with the provisions of
             the Amended and Restated Credit Agreement;

                  third, to ratable payment of accrued but unpaid interest
             (including post-petition interest) on the Secured Obligations
             and any termination payments due in respect of any Hedging
             Agreement with any Lender (pro rata in accordance with all
             such amounts due);
 
                  fourth, to the ratable payment of unpaid principal of the
             Secured Obligations;

                  fifth, to the ratable payment of all other Secured
             Obligations, until all Secured Obligations shall have been
             paid in full; and

                  finally, to payment to the applicable Grantors or their
             respective successor or assigns, or as a court of competent
             jurisdiction may direct, of any surplus then remaining from
             such proceeds.

The Administrative Agent may make distribution hereunder in cash or in
kind or, on a ratable basis, in any combination thereof.

             SECTION 11.  Concerning the Administrative Agent.  The
provisions of Article XIII of the Amended and Restated Credit Agreement
shall inure to the benefit of the Administrative Agent in respect of
this Agreement and shall be binding upon the parties to the Amended and
Restated Credit Agreement in such respect.  In furtherance and not in
derogation of the rights, privileges and immunities of the
Administrative Agent therein set forth:

             (a)  The Administrative Agent is authorized to take all such
action as is provided to be taken by it as Administrative Agent
hereunder and all other action incidental thereto.  As to any matters
not expressly provided for herein, the Administrative Agent may request
instructions from the Lenders and shall act or refrain from acting in
accordance with written instructions from the Required Lenders (or, when
expressly required by this Agreement or the Amended and Restated Credit
Agreement, all the Lenders) or, in the absence of such instructions, in
accordance with its discretion.

             (b)  The Administrative Agent shall not be responsible for the
existence, genuineness or value of any of the Collateral or for the
validity, perfection, priority or enforceability of the Security
Interests, whether impaired by operation of law or by reason of any
action or omission to act on its part (other than any such action or
inaction constituting gross negligence or willful misconduct.  The
Administrative Agent shall have no duty to ascertain or inquire as to
the performance or observance of any of the terms of this Agreement by
any Grantor.

             SECTION 12.  Appointment of Collateral Agents.  At any time or
times, in order to comply with any legal requirement in any jurisdiction
or in order to effectuate any provision of the Loan Documents, the
Administrative Agent may appoint another bank or trust company or one or
more other Persons, either to act as collateral agent or agents, jointly
with the Administrative Agent or separately, on behalf of the
Administrative Agent and the Lenders with such power and authority as
may be necessary for the effectual operation of the provisions hereof
and specified in the instrument of appointment (which may, in the
discretion of the Administrative Agent, include provisions for the
protection of such collateral agent similar to the provisions of
Section 11 hereof).

             SECTION 13.  Expenses.  In the event that any Grantor fails to
comply with the provisions of the Amended and Restated Credit Agreement,
this Agreement or any other Loan Document, such that the value of any
Collateral or the validity, perfection, rank or value of the Security
Interests are thereby diminished or potentially diminished or put at
risk, the Administrative Agent if requested by the Required Lenders may,
but shall not be required to, effect such compliance on behalf of such
Grantor, and such Grantor shall reimburse the Administrative Agent for
the reasonable costs thereof on demand.  All insurance expenses and all
reasonable expenses of protecting, storing, warehousing, insuring,
handling, maintaining and shipping the Collateral, any and all excise,
stamp, intangibles, transfer, property, sales, and use taxes imposed by
any state, federal, or local authority or any other Governmental
Authority on any of the Collateral, or in respect of the sale or other
disposition thereof, shall be borne and paid by the Grantors; and if any
Grantor fails promptly to pay any portion thereof when due, the
Administrative Agent or any Lender may, at its option, but shall not be
required to, pay the same and charge such Grantor's account therefor,
and such Grantor agrees to reimburse the Administrative Agent or such
Lender therefor on demand.  All sums so paid or incurred by the
Administrative Agent or any Lender for any of the foregoing and any and
all other sums for which any Grantor may become liable hereunder and all
costs and expenses (including reasonable attorneys' fees, legal expenses
and court costs) incurred by the Administrative Agent or any Lender in
enforcing or protecting the Security Interests or any of their rights or
remedies thereon shall be payable by the Grantors on demand and shall
bear interest (after as well as before judgment) until paid at the rate
then applicable to Base Rate Loans under the Amended and Restated Credit
Agreement and shall be additional Secured Obligations hereunder.

             SECTION 14.  Notices.  All notices, communications and
distributions hereunder shall be given or made in accordance with
Section 14.1 of the Amended and Restated Credit Agreement.

             SECTION 15.  Waivers, Non-Exclusive Remedies.  No failure on
the part of the Administrative Agent or any Lender to exercise, and no
delay in exercising and no course of dealing with respect to, any right
under the Amended and Restated Credit Agreement, this Agreement or any
other Loan Document shall operate as a waiver thereof or hereof; nor
shall any single or partial exercise by the Administrative Agent or any
Lender of any right under the Amended and Restated Credit Agreement,
this Agreement or any other Loan Document preclude any other or further
exercise thereof, and the exercise of any rights in this Agreement, the
Amended and Restated Credit Agreement and the other Loan Documents are
cumulative and are not exclusive of any other remedies provided by law. 
This Agreement is a Loan Document executed pursuant to the Amended and
Restated Credit Agreement.

             SECTION 16.  Successors and Assigns.  This Agreement is for
the benefit of the Administrative Agent and the Lenders and their
successors and assigns (as permitted by the Amended and Restated Credit
Agreement), and in the event of an assignment of all or any of the
Secured Obligations, the rights hereunder, to the extent applicable to
the indebtedness so assigned, may be transferred with such indebtedness. 
This Agreement shall be binding on each Grantor and its successor and
assigns; provided, that such Grantor may not assign any of its rights or
obligations hereunder without the prior written consent of the
Administrative Agent and the Lenders.

             SECTION 17.  Changes in Writing.  Neither this Agreement nor
any provision hereof may be changed, waived, discharged or terminated
orally, but only in writing signed by each Grantor and the
Administrative Agent with the consent of the Required Lenders (or, when
expressly required by this Agreement or the Amended and Restated Credit
Agreement, all of the Lenders).

             SECTION 18.  Powers Coupled with an Interest.  All
authorizations and agencies herein contained with respect to the
Collateral are irrevocable and powers coupled with an interest.

             SECTION 19.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED
BY, CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NORTH CAROLINA, WITHOUT REFERENCE TO THE CONFLICTS OR CHOICE OF LAW
PRINCIPLES THEREOF.

             SECTION 20.  Consent to Jurisdiction.  Each Grantor hereby
irrevocably consents to the personal jurisdiction of the state and
federal courts located in Mecklenburg County, North Carolina, in any
action, claim or other proceeding arising out of or any dispute in
connection with this Agreement, any rights or obligations hereunder, or
the performance of such rights and obligations.  Each Grantor hereby
irrevocably consents to the service of a summons and complaint and other
process in any action, claim or proceeding brought by the Administrative
Agent or any Lender in connection with this Agreement, any rights or
obligations hereunder, or the performance of such rights and
obligations, on behalf of itself or its property, in the manner provided
in Section 14.1 of the Amended and Restated Credit Agreement.  Nothing
in this Section 20 shall affect the right of the Administrative Agent or
any Lender to serve legal process in any other manner permitted by
Applicable Law or affect the right of the Administrative Agent or any
Lender to bring any action or proceeding against any Grantor or its
properties in the courts of any other jurisdictions.

             SECTION 21. Binding Arbitration; Waiver of Jury Trial.

             (a)  Binding Arbitration.  If in the reasonable determination
of the Administrative Agent and its counsel, Section 21(b) is
unenforceable under North Carolina law unless paired with a binding
arbitration provision, then upon demand of any party made within ninety
(90) days after institution of any judicial proceeding, any dispute,
claim or controversy between a Lender (or group of Lenders) and a
Borrower (or group of Borrowers) (but not any dispute, claim or
controversy among any Lenders not involving any Borrower) arising out
of, connected with or relating to this Agreement ("Disputes"), between
or among parties to this Agreement shall be resolved by binding
arbitration as provided herein.  Institution of a judicial proceeding by
a party does not waive the right of that party to demand arbitration
hereunder.  Disputes may include, without limitation, tort claims,
counterclaims, claims brought as class actions, claims arising from
supplements to this Agreement executed in the future, or claims
concerning any aspect of the past, present or future relationships
arising out of or connected with this Agreement.  Arbitration shall be
conducted under and governed by the Commercial Financial Disputes
Arbitration Rules (the "Arbitration Rules") of the American Arbitration
Association and Title 9 of the U.S. Code.  All arbitration hearings
shall be conducted in Charlotte, North Carolina.  The expedited
procedures set forth in Rule 51, et seq. of the Arbitration Rules shall
be applicable to claims of less than $1,000,000.  All applicable
statutes of limitation shall apply to any Dispute.  A judgment upon the
award may be entered in any court having jurisdiction.  The panel from
which all arbitrators are selected shall be comprised of licensed
attorneys.  The single arbitrator selected for expedited procedure shall
be a retired judge from the highest court of general jurisdiction, state
or federal, of the state where the hearing will be conducted.

             (b)  Jury Trial.  EACH AGENT, LENDER AND THE PLEDGOR HEREBY
IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT
TO ANY ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN
CONNECTION WITH THIS AGREEMENT, THE NOTES OR THE OTHER LOAN DOCUMENTS,
ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE PERFORMANCE OF
SUCH RIGHTS AND OBLIGATIONS.

             (c)  Preservation of Certain Remedies.  Notwithstanding the
preceding binding arbitration provisions, the parties hereto preserve,
without diminution, certain remedies that such Persons may employ or
exercise freely, either alone, in conjunction with or during a Dispute. 
Each such Person shall have and hereby reserves the right to proceed in
any court of proper jurisdiction or by self help to exercise or
prosecute the following remedies:  (i) all rights to foreclose against
any real or personal property or other security by exercising a power of
sale granted in this Agreement or under applicable law or by judicial
foreclosure and sale, (ii) all rights of self help including peaceful
occupation of property and collection of rents, set off, and peaceful
possession of property, (iii) obtaining provisional or ancillary
remedies including injunctive relief, sequestration, garnishment,
attachment, appointment of receiver and in filing an involuntary
bankruptcy proceeding, and (iv) when applicable, a judgment by
confession of judgment.  Preservation of these remedies does not limit
the power of an arbitrator to grant similar remedies that may be
requested by a party in a Dispute.  

             SECTION 22.  Severability.  If any provision hereof is invalid
and unenforceable in any jurisdiction, then, to the fullest extent
permitted by law, (a) the other provisions hereof shall remain in full
force and effect in such jurisdiction and shall be liberally construed
in favor of the Administrative Agent and the Lenders in order to carry
out the intentions of the parties hereto as nearly as may be possible;
and (b) the invalidity or unenforceability of any provisions hereof in
any jurisdiction shall not affect the validity or enforceability of such
provision in any other jurisdiction.

             SECTION 23.  Headings.  The various headings of this Agreement
are inserted for convenience only and shall not affect the meaning or
interpretation of this Agreement or any provisions hereof.

             SECTION 24.  Counterparts.  This Agreement may be executed by
the parties hereto in several counterparts, each of which shall be
deemed to be an original and all of which shall constitute together but
one and the same agreement.
