         3. Provisions Relating to Accounts.

                  (a) Anything herein to the contrary notwithstanding, each of

         and perform all the conditions and obligations to be observed and
         performed by it thereunder, all in accordance with the terms of any
         agreement giving rise to each such Account. Neither the Agent nor any
         Lender shall have any obligation or liability under any Account (or any
         agreement giving rise thereto) by reason of or arising out of this
         Security Agreement or the receipt by the Agent or any Lender of any
         payment relating to such Account pursuant hereto, nor shall the Agent
         or any Lender be obligated in any manner to perform any of the
         obligations of an Obligor under or pursuant to any Account (or any
         agreement giving rise thereto), to make any payment, to make any
         inquiry as to the nature or the sufficiency of any payment received by
         it or as to the sufficiency of any performance by any party under any
         Account (or any agreement giving rise thereto), to present or file any
         claim, to take any action to enforce any performance or to collect the
         payment of any amounts which may have been assigned to it or to which
         it may be entitled at any time or times.

                  (b) Once during each calendar year or at any time after the
         occurrence and during the continuation of an Event of Default, the
         Agent shall have the right, but not the obligation, upon prior written
         notice to the Obligors, to make test verifications of the Accounts in
         any manner and through any medium that it reasonably considers
         advisable, and the Obligors shall furnish all such assistance and
         information as the Agent may require in connection with such test
         verifications. After the occurrence and during the continuance of an
         Event of Default, upon the Agent's request and at the expense of the
         Agent, the Obligors shall cause independent public accountants or
         others satisfactory to the Agent to furnish to the Agent reports
         showing reconciliations, aging and test verifications of, and trial
         balances for, the Accounts. After the occurrence and during the
         continuance of an Event of Default, the Agent in its own name or in the
         name of others 



                                     - 4 -

         them to the Agent's satisfaction the existence, amount and terms of any
         Accounts.

         4. Representations and Warranties. Each Obligor hereby represents and
warrants to the Agent, for the benefit of the Lenders, that so long as any of
the Secured Obligations remain outstanding or any Credit Document or Hedging
Agreement is in effect or any Letter of Credit shall remain outstanding, and
until all of the Commitments shall have been terminated:

                  (a) Chief Executive Office; Books & Records. Each Obligor's
         chief executive office and chief place of business is (and for the

         such locations.

                  (b) Location of Collateral. The location of all Collateral
         owned by each Obligor is as shown on Schedule 4(b) hereto.

         Agreement and no Obligor has in the past four months changed its name,
         been party to a merger, consolidation or other change in structure or
         used any tradename except as set forth in Schedule 4(c) attached
         hereto.

                  (d) Security Interest/Priority. This Security Agreement
         creates a valid security interest in favor of the Agent, for the
         benefit of the Lenders, in the Collateral of such Obligor and, when
         properly perfected by filing, shall constitute a valid perfected
         security interest in such Collateral, to the extent such security can
         be perfected by filing under the UCC, free and clear of all Liens
         except for Permitted Liens.

                  (e) Farm Products. None of the Collateral constitutes, or is
         the Proceeds of, Farm Products.

         and documents relating thereto are genuine and in all material respects
         what they purport to be, (ii) each Account arises out of (A) a bona
         fide sale of goods sold and delivered by such Obligor (or is in the
         process of being delivered) or (B) services theretofore actually
         rendered by such Obligor to, the account debtor named therein, (iii) no

         over and delivered to the Agent and (iv) no surety bond was required or
         given in connection with any Account of an Obligor or the contracts or
         purchase orders out of which they arose.

                  (g) Inventory. No Inventory is held by an Obligor pursuant to
         consignment, sale or return, sale on approval or similar arrangement.

                  (h) Copyrights, Patents and Trademarks.

                  and Trademarks are valid and enforceable.

                           (vii) No Obligor has made any assignment or agreement

         Agreement or any other agreement relating to the Collateral or any
         policy insuring the Collateral or any applicable statute, law, bylaw,
         rule, regulation or ordinance.

                  (c) Instruments/Chattel Paper. If any amount payable under or
         in connection with any of the Collateral shall be or become evidenced

         to the Agent, to be held as Collateral pursuant to this Security
         Agreement.

                  (d) Change in Location. Not, without providing 30 days prior
         written notice to the Agent and without filing such amendments to any
         previously filed financing statements as the Agent may require, (a)
         change the location of its chief executive office and chief place of
         business (as well as its books and records) from the locations set
         forth on Schedule 4(a) hereto, (b) change the location of its
         Collateral from the locations set forth for such Obligor on Schedule

         existing documents, as the Agent may reasonably request) and do all
         such other things as the Agent may reasonably deem necessary or
         appropriate (i) to assure to the Agent its security interests
         hereunder, including (A) such financing statements (including renewal
         statements) or amendments thereof or supplements thereto or other

         all of the Collateral of such Obligor without, to the extent permitted
         by law, such Obligor's signature thereon, and further each Obligor also
         hereby irrevocably makes, constitutes and appoints the Agent, its
         nominee or any other person whom the Agent may designate, as such
         Obligor's attorney in fact with full power and for the limited purpose
         to sign in the name of such Obligor any such financing statements, or
         amendments and supplements to financing statements, renewal financing

         statements, notices or any similar documents which in the Agent's
         reasonable discretion would be necessary, appropriate or convenient in
         order to perfect and maintain perfection of the security interests
         granted hereunder, such power, being coupled with an interest, being
         and remaining irrevocable so long as the Credit Agreement is in effect
         or any amounts payable thereunder or under any other Credit Document,
         any Letter of Credit or any Hedging Agreement shall remain outstanding,
         and until all of the Commitments thereunder shall have terminated. Each
         Obligor hereby agrees that a carbon, photographic or other reproduction
         of this Security Agreement or any such financing statement is
         sufficient for filing as a financing statement by the Agent without
         notice thereof to such Obligor wherever the Agent may in its sole
         discretion desire to file the same. In the event for any reason the law
         of any jurisdiction other than North Carolina becomes or is applicable
         to the Collateral of any Obligor or any part thereof, or to any of the
         Secured Obligations, such Obligor agrees to execute and deliver all
         such instruments and to do all such other things as the Agent in its
         sole discretion reasonably deems necessary or appropriate to preserve,
         protect and enforce the security interests of the Agent under the law
         of such other jurisdiction (and, if an Obligor shall fail to do so
         promptly upon the request of the Agent, then the Agent may execute any
         and all such requested documents on behalf of such Obligor pursuant to
         the power of attorney granted hereinabove). If any Collateral is in the
         possession or control of an Obligor's agents and the Agent so requests,
         such Obligor agrees to notify such agents in writing of the Agent's
         security interest therein and, upon the occurrence of and during the
         continuation of and Event of Default, upon the Agent's request,
         instruct them to hold all such Collateral for the Lenders' account and
         subject to the Agent's instructions. Each Obligor agrees to mark its
         books and records to reflect the security interest of the Agent in the
         Collateral.

                  (g) Treatment of Accounts. Not grant or extend the time for
         payment of any Account, or compromise or settle any Account for less
         than the full amount thereof, or release any person or property, in
         whole or in part, from payment thereof, or allow any credit or discount
         thereon, other than as normal and customary in the ordinary course of
         an Obligor's business.

                  (h) Covenants Relating to Copyrights.

                           (i)  Employ the Copyright for each Work with such
                  notice of copyright as may be required by law to secure
                  copyright protection.

                           (ii) Not do any act or knowingly omit to do any act
                  whereby any material Copyright may become invalidated and (A)
                  not do any act, or knowingly omit to do any act, whereby any
                  material Copyright may become injected into the public domain;
                  (B) notify the Agent immediately if it knows, or has reason to
                  know, that any material Copyright may become injected into the
                  public domain or of any adverse determination or development
                  (including, without limitation, the institution of, or any
                  such determination or development in, any court or tribunal in
                  the United States or any other country) regarding an Obligor's
                  ownership of any such Copyright or its validity; (C) take all
                  necessary steps as it

                  shall deem appropriate under the circumstances, to maintain
                  and pursue each application (and to obtain the relevant
                  registration) and to maintain each registration of each
                  material Copyright owned by an Obligor including, without
                  limitation, filing of applications for renewal where
                  necessary; and (D) promptly notify the Agent of any material
                  infringement of any material Copyright of an Obligor of which
                  it becomes aware and take such actions as it shall reasonably
                  deem appropriate under the circumstances to protect such
                  Copyright, including, where appropriate, the bringing of suit
                  for infringement, seeking injunctive relief and seeking to
                  recover any and all damages for such infringement.

                           (iii) Not make any assignment or agreement in
                  conflict with the security interest in the Copyrights of each
                  Obligor hereunder.

                  (i) Covenants Relating to Patents and Trademarks.

                           (i)   (A) Continue to use each Trademark on each and
                  every trademark class of goods applicable to its current line
                  as reflected in its current catalogs, brochures and price
                  lists in order to maintain such Trademark in full force free
                  from any claim of abandonment for non-use, (B) maintain as in
                  the past the quality of products and services offered under
                  such Trademark, (C) employ such Trademark with the appropriate
                  notice of registration, (D) not adopt or use any mark which is
                  confusingly similar or a colorable imitation of such Trademark
                  unless the Agent, for the ratable benefit of the Lenders,
                  shall obtain a perfected security interest in such mark
                  pursuant to this Security Agreement, and (E) not (and not
                  permit any licensee or sublicensee thereof to) do any act or
                  knowingly omit to do any act whereby any Trademark may become
                  invalidated.

                           (ii)  Not do any act, or omit to do any act, whereby
                  any Patent may become abandoned or dedicated.

                           (iii) Notify the Agent and the Lenders within a
                  reasonable time if it knows, or has reason to know, that any
                  application or registration relating to any Patent or
                  Trademark may become abandoned or dedicated, or 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 or tribunal in any country) regarding an
                  Obligor's ownership of any Patent or Trademark or its right to
                  register the same or to keep and maintain the same.

                           (iv)  Whenever an Obligor, either by itself or
                  through an agent, employee, licensee or designee, shall 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, an Obligor shall report such filing to
                  the Agent and the Lenders within fifteen Business Days after
                  the last day of the fiscal quarter in which such filing
                  occurs. 


                                     - 9 -
   10

                  Upon request of the Agent, an Obligor shall execute and
                  deliver any and all agreements, instruments, documents and
                  papers as the Agent may request to evidence the Agent's and
                  the Lenders' security interest in any Patent or Trademark and
                  the goodwill and general intangibles of an Obligor relating
                  thereto or represented thereby.

                           (v)   Take all reasonable and necessary steps,
                  including, without limitation, in any proceeding before the
                  United States Patent and Trademark Office, or any similar
                  office or agency in any other country or any political
                  subdivision thereof, to maintain and pursue each application
                  (and to obtain the relevant registration) and to maintain each
                  registration of the Patents and Trademarks, including, without
                  limitation, filing of applications for renewal, affidavits of
                  use and affidavits of incontestability.

                           (vi)  Promptly notify the Agent and the Lenders after
                  it learns that any Patent or Trademark included in the
                  Collateral is infringed, misappropriated or diluted by a third
                  party and promptly sue for infringement, misappropriation or
                  dilution, to seek injunctive relief where appropriate and to
                  recover any and all damages for such infringement,
                  misappropriation or dilution, or take such other actions as it
                  shall reasonably deem appropriate under the circumstances to
                  protect such Patent or Trademark.

                           (vii) Not make any assignment or agreement in
                  conflict with the security interest in the Patents or
                  Trademarks of each Obligor hereunder.

                  (j) New Patents, Copyrights and Trademarks. Promptly provide
         the Agent with (i) a listing of all applications, if any, for new
         Copyrights, Patents or Trademarks (together with a listing of the
         issuance of registrations or letters on present applications), which
         new applications and issued registrations or letters shall be subject
         to the terms and conditions hereunder, and (ii) (A) with respect to
         Copyrights, a duly executed Notice of Security Interest in Copyrights,
         (B) with respect to Patents, a duly executed Notice of Security
         Interest in Patents, (C) with respect to Trademarks, a duly executed
         Notice of Security Interest in Trademarks or (D) such other duly
         executed documents as the Agent may request in a form acceptable to
         counsel for the Agent and suitable for recording to evidence the
         security interest in the Copyright, Patent or Trademark which is the
         subject of such new application.

                  (k) Insurance. Insure, repair and replace the Collateral of
         such Obligor as set forth in the Credit Agreement. All insurance
         proceeds shall be subject to the security interest of the Agent
         hereunder.

         6. Advances by Lenders. On failure of any Obligor to perform any of the
covenants and agreements contained herein, the Agent may, at its sole option and
in its sole discretion, perform the same and in so doing may expend such sums as
the Agent may reasonably deem advisable in the performance thereof, including,
without limitation, the payment of any insurance 


                                     - 10 -
   11

premiums, the payment of any taxes, a payment to obtain a release of a Lien or
potential Lien, expenditures made in defending against any adverse claim and all
other expenditures which the Agent or the Lenders may make for the protection of
the security hereof or which may be compelled to make by operation of law. All
such sums and amounts so expended shall be repayable by the Obligors on a joint
and several basis promptly upon timely notice thereof and demand therefor, shall
constitute additional Secured Obligations and shall bear interest from the date
said amounts are expended at the default rate specified in Section 3.1 of the
Credit Agreement for Loans that are Base Rate Loans. No such performance of any
covenant or agreement by the Agent or the Lenders on behalf of any Obligor, and
no such advance or expenditure therefor, shall relieve the Obligors of any
default under the terms of this Security Agreement, the other Credit Documents
or any Hedging Agreement. The Lenders may make any payment hereby authorized in
accordance with any bill, statement or estimate procured from the appropriate
public office or holder of the claim to be discharged without inquiry into the
accuracy of such bill, statement or estimate or into the validity of any tax
assessment, sale, forfeiture, tax lien, title or claim except to the extent such
payment is being contested in good faith by an Obligor in appropriate
proceedings and against which adequate reserves are being maintained in
accordance with GAAP.

         7. Events of Default.

         The occurrence of an event which under the Credit Agreement would
constitute an Event of Default shall be an Event of Default hereunder (an "Event
of Default").

         8. Remedies.

                  (a) General Remedies. Upon the occurrence of an Event of
         Default and during continuation thereof, the Lenders shall have, in
         addition to the rights and remedies provided herein, in the Credit
         Documents, in the Hedging Agreements or by law (including, but not
         limited to, the rights and remedies set forth in the Uniform Commercial
         Code of the jurisdiction applicable to the affected Collateral), the
         rights and remedies of a secured party under the UCC (regardless of
         whether the UCC is the law of the jurisdiction where the rights and
         remedies are asserted and regardless of whether the UCC applies to the
         affected Collateral), and further, the Agent may, with or without
         judicial process or the aid and assistance of others, (i) enter on any
         premises on which any of the Collateral may be located and, without
         resistance or interference by the Obligors, take possession of the
         Collateral, (ii) dispose of any Collateral on any such premises, (iii)
         require the Obligors to assemble and make available to the Agent at the
         expense of the Obligors any Collateral at any place and time designated
         by the Agent which is reasonably convenient to both parties, (iv)
         remove any Collateral from any such premises for the purpose of
         effecting sale or other disposition thereof, and/or (v) without demand
         and without advertisement, notice, hearing or process of law, all of
         which each of the Obligors hereby waives to the fullest extent
         permitted by law, at any place and time or times, sell and deliver any
         or all Collateral held by or for it at public or private sale, by one
         or more contracts, in one or more parcels, for cash, upon credit or
         otherwise, at such prices and upon such terms as the Agent deems
         advisable, in its sole discretion (subject to any and all mandatory
         legal 


                                     - 11 -
   12


         requirements). In addition to all other sums due the Agent and the
         Lenders with respect to the Secured Obligations, the Obligors shall pay
         the Agent and each of the Lenders all reasonable documented costs and
         expenses incurred by the Agent or any such Lender, including, but not
         limited to, reasonable attorneys' fees and court costs, in obtaining or
         liquidating the Collateral, in enforcing payment of the Secured
         Obligations, or in the prosecution or defense of any action or
         proceeding by or against the Agent or the Lenders or the Obligors
         concerning any matter arising out of or connected with this Security
         Agreement, any Collateral or the Secured Obligations, including,
         without limitation, any of the foregoing arising in, arising under or
         related to a case under the Bankruptcy Code. To the extent the rights
         of notice cannot be legally waived hereunder, each Obligor agrees that
         any requirement of reasonable notice shall be met if such notice is
         personally served on or mailed, postage prepaid, to the Borrower in
         accordance with the notice provisions of Section 11.1 of the Credit
         Agreement at least 10 days before the time of sale or other event
         giving rise to the requirement of such notice. The Agent and the
         Lenders shall not be obligated to make any sale or other disposition of
         the Collateral regardless of notice having been given. To the extent
         permitted by law, any Lender may be a purchaser at any such sale. To
         the extent permitted by applicable law, each of the Obligors hereby
         waives all of its rights of redemption with respect to any such sale.
         Subject to the provisions of applicable law, the Agent and the Lenders
         may postpone or cause the postponement of the sale of all or any
         portion of the Collateral by announcement at the time and place of such
         sale, and such sale may, without further notice, to the extent
         permitted by law, be made at the time and place to which the sale was
         postponed, or the Agent and the Lenders may further postpone such sale
         by announcement made at such time and place.

                  (b) Remedies relating to Accounts. Upon the occurrence of an
         Event of Default and during the continuation thereof, whether or not
         the Agent has exercised any or all of its rights and remedies
         hereunder, each Obligor will promptly upon request of the Agent
         instruct all account debtors to remit all payments in respect of
         Accounts to a mailing location selected by the Agent. In addition, the
         Agent or its designee may notify any Obligor's customers and account
         debtors that the Accounts of such Obligor have been assigned to the
         Agent or of the Agent's security interest therein, and may (either in
         its own name or in the name of an Obligor or both) demand, collect
         (including without limitation by way of a lockbox arrangement),
         receive, take receipt for, sell, sue for, compound, settle, compromise
         and give acquittance for any and all amounts due or to become due on
         any Account, and, in the Agent's discretion, file any claim or take any
         other action or proceeding to protect and realize upon the security
         interest of the Lenders in the Accounts. Each Obligor acknowledges and
         agrees that the Proceeds of its Accounts remitted to or on behalf of
         the Agent in accordance with the provisions hereof shall be solely for
         the Agent's own convenience and that such Obligor shall not have any
         right, title or interest in such Accounts or in any such other amounts
         except as expressly provided herein. The Agent and the Lenders shall
         have no liability or responsibility to any Obligor for acceptance of a
         check, draft or other order for payment of money bearing the legend
         "payment in full" or words of similar import or any other restrictive
         legend or endorsement or be responsible for determining the correctness
         of any remittance unless such acceptance was willful or with gross
         negligence. Each Obligor hereby agrees to indemnify the Agent


                                     - 12 -
   13

         and the Lenders from and against all liabilities, damages, losses,
         actions, claims, judgments, costs, expenses, charges and reasonable
         attorneys' fees suffered or incurred by the Agent or the Lenders (each,
         an "Indemnified Party") because of the maintenance of the foregoing
         arrangements except as relating to or arising out of the gross
         negligence or willful misconduct of an Indemnified Party or its
         officers, employees or agents. In the case of any investigation,
         litigation or other proceeding, the foregoing indemnity shall be
         effective whether or not such investigation, litigation or proceeding
         is brought by an Obligor, its directors, shareholders or creditors or
         an Indemnified Party or any other Person or any other Indemnified Party
         is otherwise a party thereto.

                  (c) Access. In addition to the rights and remedies hereunder,
         upon the occurrence of an Event of Default and during the continuance
         thereof, the Agent shall have the right to enter and remain upon the
         various premises of the Obligors without cost or charge to the Agent,
         and use the same, together with materials, supplies, books and records
         of the Obligors for the purpose of collecting and liquidating the
         Collateral, or for preparing for sale and conducting the sale of the
         Collateral, whether by foreclosure, auction or otherwise. In addition,
         the Agent may remove Collateral, or any part thereof, from such
         premises and/or any records with respect thereto, in order to
         effectively collect or liquidate such Collateral.

                  (d) Nonexclusive Nature of Remedies. Failure by the Agent or
         the Lenders to exercise any right, remedy or option under this Security
         Agreement, any other Credit Document, any Hedging Agreement or as
         provided by law, or any delay by the Agent or the Lenders in exercising
         the same, shall not operate as a waiver of any such right, remedy or
         option. No waiver hereunder shall be effective unless it is in writing,
         signed by the party against whom such waiver is sought to be enforced
         and then only to the extent specifically stated, which in the case of
         the Agent or the Lenders shall only be granted as provided herein. To
         the extent permitted by law, neither the Agent, the Lenders, nor any
         party acting as attorney for the Agent or the Lenders, shall be liable
         hereunder for any acts or omissions or for any error of judgment or
         mistake of fact or law other than their gross negligence or willful
         misconduct hereunder. The rights and remedies of the Agents and the
         Lenders under this Security Agreement shall be cumulative and not
         exclusive of any other right or remedy which the Agent or the Lenders
         may have.

                  (e) Retention of Collateral. The Agent may, after providing
         the notices required by Section 9-505(2) of the UCC or otherwise
         complying with the requirements of applicable law of the relevant
         jurisdiction, to the extent the Agent is in possession of any of the
         Collateral, retain the Collateral in satisfaction of the Secured
         Obligations. Unless and until the Agent shall have provided such
         notices, however, the Agent shall not be deemed to have retained any
         Collateral in satisfaction of any Secured Obligations for any reason.

                  (f) Deficiency. In the event that the proceeds of any sale,
         collection or realization are insufficient to pay all amounts to which
         the Agent or the Lenders are legally entitled, the Obligors shall be
         jointly and severally liable for the deficiency, together with


                                     - 13 -
   14


         interest thereon at the default rate specified in Section 3.1 of the
         Credit Agreement for Loans that are Base Rate Loans, together with the
         costs of collection and the reasonable fees of any attorneys employed
         by the Agent to collect such deficiency. Any surplus remaining after
         the full payment and satisfaction of the Secured Obligations shall be
         returned to the Obligors or to whomsoever a court of competent
         jurisdiction shall determine to be entitled thereto.

         9. Rights of the Agent.

                  (a) Power of Attorney. In addition to other powers of attorney
         contained herein, each Obligor hereby designates and appoints the
         Agent, on behalf of the Lenders, and each of its designees or agents,
         as attorney-in-fact of such Obligor, irrevocably and with power of
         substitution, with authority to take any or all of the following
         actions upon the occurrence and during the continuance of an Event of
         Default:

                           (i)   to demand, collect, settle, compromise, adjust,
                  give discharges and releases, all as the Agent may reasonably
                  determine;

                           (ii)  to commence and prosecute any actions at any
                  court for the purposes of collecting any Collateral and
                  enforcing any other right in respect thereof;

                           (iii) to defend, settle or compromise any action
                  brought and, in connection therewith, give such discharge or
                  release as the Agent may deem reasonably appropriate;

                           (iv)  receive, open and dispose of mail addressed to
                  an Obligor and endorse checks, notes, drafts, acceptances,
                  money orders, bills of lading, warehouse receipts or other
                  instruments or documents evidencing payment, shipment or
                  storage of the goods giving rise to the Collateral of such
                  Obligor on behalf of and in the name of such Obligor, or
                  securing, or relating to such Collateral;

                           (v)   sell, assign, transfer, make any agreement in
                  respect of, or otherwise deal with or exercise rights in
                  respect of, any Collateral or the goods or services which have
                  given rise thereto, as fully and completely as though the
                  Agent were the absolute owner thereof for all purposes;

                           (vi)  adjust and settle claims under any insurance
                  policy relating thereto;

                           (vii) execute and deliver all assignments,
                  conveyances, statements, financing statements, renewal
                  financing statements, security agreements, affidavits, notices
                  and other agreements, instruments and documents that the Agent
                  may determine necessary in order to perfect and


                                     - 14 -
   15

                  maintain the security interests and liens granted in this
                  Security Agreement and in order to fully consummate all of the
                  transactions contemplated therein;

                           (viii) institute any foreclosure proceedings that the
                  Agent may deem appropriate; and

                           (ix)   do and perform all such other acts and things
                  as the Agent may reasonably deem to be necessary, proper or
                  convenient in connection with the Collateral.

         This power of attorney is a power coupled with an interest and shall be
         irrevocable (i) for so long as any of the Secured Obligations remain
         outstanding, any Credit Document or any Hedging Agreement is in effect
         or any Letter of Credit shall remain outstanding and (ii) until all of
         the Commitments shall have been terminated. The Agent shall be under no
         duty to exercise or withhold the exercise of any of the rights, powers,
         privileges and options expressly or implicitly granted to the Agent in
         this Security Agreement, and shall not be liable for any failure to do
         so or any delay in doing so. The Agent shall not be liable for any act
         or omission or for any error of judgment or any mistake of fact or law
         in its individual capacity or its capacity as attorney-in-fact except
         acts or omissions resulting from its gross negligence or willful
         misconduct. This power of attorney is conferred on the Agent solely to
         protect, preserve and realize upon its security interest in the
         Collateral.

                  (b) Performance by the Agent of Obligations. If any Obligor
         fails to perform any agreement or obligation contained herein, the
         Agent itself may perform, or cause performance of, such agreement or
         obligation, and the expenses of the Agent incurred in connection
         therewith shall be payable by the Obligors on a joint and several basis
         pursuant to Section 11 hereof.

                  (c) Assignment by the Agent. The Agent may from time to time
         assign the Secured Obligations and any portion thereof and/or the
         Collateral and any portion thereof, and the assignee shall be entitled
         to all of the rights and remedies of the Agent under this Security
         Agreement in relation thereto.

                  (d) The Agent's Duty of Care. Other than the exercise of
         reasonable care to assure the safe custody of the Collateral while
         being held by the Agent hereunder, the Agent shall have no duty or
         liability to preserve rights pertaining thereto, it being understood
         and agreed that the Obligors shall be responsible for preservation of
         all rights in the Collateral, and the Agent shall be relieved of all
         responsibility for the Collateral upon surrendering it or tendering the
         surrender of it to the Obligors. The Agent shall be deemed to have
         exercised reasonable care in the custody and preservation of the
         Collateral in its possession if the Collateral is accorded treatment
         substantially equal to that which the Agent accords its own property,
         which shall be no less than the treatment employed by a reasonable and
         prudent agent in the industry, it being understood that the Agent shall
         not 


                                     - 15 -
   16

         have responsibility for taking any necessary steps to preserve rights
         against any parties with respect to any of the Collateral.

         10. Application of Proceeds. Upon the occurrence and during the
continuance of an Event of Default, any payments in respect of the Secured
Obligations and any proceeds of the Collateral, when received by the Agent or
any of the Lenders in cash or its equivalent, will be applied in reduction of
the Secured Obligations in the order set forth in Section 3.15(b) of the Credit
Agreement, and each Obligor irrevocably waives the right to direct the
application of such payments and proceeds and acknowledges and agrees that the
Agent shall have the continuing and exclusive right to apply and reapply any and
all such payments and proceeds in the Agent's sole discretion, notwithstanding
any entry to the contrary upon any of its books and records.

         11. Costs of Counsel. If at any time hereafter, whether upon the
occurrence of an Event of Default or not, the Agent employs counsel to prepare
or consider amendments, waivers or consents with respect to this Security
Agreement, or to take action or make a response in or with respect to any legal
or arbitral proceeding relating to this Security Agreement or relating to the
Collateral, or to reasonably protect the Collateral or reasonably exercise any
rights or remedies under this Security Agreement or with respect to the
Collateral, then the Obligors agree to promptly pay upon demand any and all such
reasonable documented costs and expenses of the Agent or the Lenders, all of
which costs and expenses shall constitute Secured Obligations hereunder.

         12. Continuing Agreement.

                  (a) This Security Agreement shall be a continuing agreement in
         every respect and shall remain in full force and effect so long as any
         of the Secured Obligations remain outstanding or any Credit Document or
         Hedging Agreement is in effect or any Letter of Credit shall remain
         outstanding, and until all of the Commitments thereunder shall have
         terminated (other than any obligations with respect to the indemnities
         and the representations and warranties set forth in the Credit
         Documents). Upon such payment and termination, this Security Agreement
         shall be automatically terminated and the Agent and the Lenders shall,
         upon the request and at the expense of the Obligors, forthwith release
         all of its liens and security interests hereunder and shall execute and
         deliver all UCC termination statements and/or other documents
         reasonably requested by the Obligors evidencing such termination.
         Notwithstanding the foregoing all releases and indemnities provided
         hereunder shall survive termination of this Security Agreement.

                  (b) This Security Agreement shall continue to be effective or
         be automatically reinstated, as the case may be, if at any time
         payment, in whole or in part, of any of the Secured Obligations is
         rescinded or must otherwise be restored or returned by the Agent or any
         Lender as a preference, fraudulent conveyance or otherwise under any
         bankruptcy, insolvency or similar law, all as though such payment had
         not been made; provided that in the event payment of all or any part of
         the Secured Obligations is rescinded or must be restored or returned,
         all reasonable costs and expenses (including without limitation any
         reasonable legal fees and disbursements) incurred by the Agent or any
         Lender in defending 


                                     - 16 -
   17

         and enforcing such reinstatement shall be deemed to be included as a
         part of the Secured Obligations.

         13. Amendments; Waivers; Modifications. This Security Agreement and the
provisions hereof may not be amended, waived, modified, changed, discharged or
terminated except as set forth in Section 11.6 of the Credit Agreement.

         14. Successors in Interest. This Security Agreement shall create a
continuing security interest in the Collateral and shall be binding upon each
Obligor, its successors and assigns and shall inure, together with the rights
and remedies of the Agent and the Lenders hereunder, to the benefit of the Agent
and the Lenders and their successors and permitted assigns; provided, however,
that none of the Obligors may assign its rights or delegate its duties hereunder
without the prior written consent of each Lender or the Required Lenders, as
required by the Credit Agreement. To the fullest extent permitted by law, each
Obligor hereby releases the Agent and each Lender, and its successors and
assigns, from any liability for any act or omission relating to this Security
Agreement or the Collateral, except for any liability arising from the gross
negligence or willful misconduct of the Agent, or such Lender, or its officers,
employees or agents.

         15. Notices. All notices required or permitted to be given under this
Security Agreement shall be in conformance with Section 11.1 of the Credit
Agreement.

         16. Counterparts. This Security Agreement may be executed in any number
of counterparts, each of which where so executed and delivered shall be an
original, but all of which shall constitute one and the same instrument. It
shall not be necessary in making proof of this Security Agreement to produce or
account for more than one such counterpart.

         17. Headings. The headings of the sections and subsections hereof are
provided for convenience only and shall not in any way affect the meaning or
construction of any provision of this Security Agreement.

         18. Governing Law; Submission to Jurisdiction; Venue.

                  (a) THIS SECURITY AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
         THE PARTIES HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND
         INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH CAROLINA.
         Any legal action or proceeding with respect to this Security Agreement
         may be brought in the courts of the State of North Carolina, or of the
         United States for the Western District of North Carolina, and, by
         execution and delivery of this Security Agreement, each Obligor hereby
         irrevocably accepts for itself and in respect of its property,
         generally and unconditionally, the jurisdiction of such courts. Each
         Obligor further irrevocably consents to the service of process out of
         any of the aforementioned courts in any such action or proceeding by
         the mailing of copies thereof by registered or certified mail, postage
         prepaid, to it at the address for notices pursuant to Section 11.1 of
         the Credit Agreement, such service to become 


                                     - 17 -
   18

         effective 30 days after such mailing. Nothing herein shall affect the
         right of the Agent to serve process in any other manner permitted by
         law or to commence legal proceedings or to otherwise proceed against
         any Obligor in any other jurisdiction.

                  (b) Each Obligor hereby irrevocably waives any objection which
         it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this Security Agreement brought in the courts referred to in subsection
         (a) hereof and hereby further irrevocably waives and agrees not to
         plead or claim in any such court that any such action or proceeding
         brought in any such court has been brought in an inconvenient forum.

         19. Waiver of Jury Trial. TO THE EXTENT PERMITTED BY APPLICABLE LAW,
EACH OF THE PARTIES TO THIS SECURITY AGREEMENT HEREBY IRREVOCABLY WAIVES ALL
RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF
OR RELATING TO THIS SECURITY AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         20. Severability. If any provision of any of the Security Agreement is
determined to be illegal, invalid or unenforceable, such provision shall be
fully severable and the remaining provisions shall remain in full force and
effect and shall be construed without giving effect to the illegal, invalid or
unenforceable provisions.

         21. Entirety. This Security Agreement, the other Credit Documents and
the Hedging Agreements represent the entire agreement of the parties hereto and
thereto, and supersede all prior agreements and understandings, oral or written,
if any, including any commitment letters or correspondence relating to the
Credit Documents, the Hedging Agreements or the transactions contemplated herein
and therein.

         22. Survival. All representations and warranties of the Obligors
hereunder shall survive the execution and delivery of this Security Agreement,
the other Credit Documents and the Hedging Agreements, the delivery of the Notes
and the making of the Loans and the issuance of the Letters of Credit under the
Credit Agreement.

         23. Other Security. To the extent that any of the Secured Obligations
are now or hereafter secured by property other than the Collateral (including,
without limitation, real property and securities owned by an Obligor), or by a
guarantee, endorsement or property of any other Person, then the Agent and the
Lenders shall have the right to proceed against such other property, guarantee
or endorsement upon the occurrence and during the continuance of any Event of
Default, and the Agent and the Lenders have the right, in their sole discretion,
to determine which rights, security, liens, security interests or remedies the
Agent and the Lenders shall at any time pursue, relinquish, subordinate, modify
or take with respect thereto, without in any way modifying or affecting any of
them or any of the Agent's and the Lenders' rights or the Secured Obligations
under this Security Agreement, under any other of the Credit Documents or under
any Hedging Agreement.

         24. Joint and Several Obligations of Obligors.

                  (a) Each of the Obligors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the Lenders under the Credit Agreement, for the mutual
         benefit, directly and indirectly, of each of the Obligors and in
         consideration of the undertakings of each of the Obligors to accept
         joint and several liability for the obligations of each of them.

                  (b) Each of the Obligors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Obligors with respect to the payment and performance of all of the
         Secured Obligations arising under this Security Agreement, the other
         Credit Documents and the Hedging Agreements, it being the intention of
         the parties hereto that all the Obligations shall be the joint and
         several obligations of each of the Obligors without preferences or
         distinction among them.

                  (c) Notwithstanding any provision to the contrary contained
         herein or in any other of the Credit Documents, to the extent the
         obligations of a Guarantor shall be adjudicated to be invalid or
         unenforceable for any reason (including, without limitation, because of
         any applicable state or federal law relating to fraudulent conveyances
         or transfers) then the obligations of each Guarantor hereunder shall be
         limited to the maximum amount that is permissible under applicable law
         (whether federal or state and including, without limitation, the
         Bankruptcy Code).

         25. Rights of Required Lenders. All rights of the Agent hereunder, if
not exercised by the Agent, may be exercised by the Required Lenders.
