ADDITIONAL SECURITIES; STOCK SPLITS; STOCK DIVIDENDS. 4.1 ADDITIONAL SECURITIES. Pledgor agrees that in the event that Pledgor, by virtue of the ownership by Pledgor of the Collateral, now is, or hereafter becomes, entitled (with or without additional consideration) to other or additional capital stock as the result of any reorganization, merger, consolidation, stock split, stock dividend, conversion, exercise of warrant or preemptive right or otherwise, Pledgor shall: 4.1.1 DELIVERY. Cause the issuer of such additional capital stock to deliver to or as directed by Pledgees all certificates and other documents, if any, evidencing the ownership by Pledgor of such additional capital stock and hereby authorizes and empowers Pledgees to demand the same from such issuer, and agrees if such certificates and other documents are delivered to Pledgor, to take possession thereof in trust for Pledgees; 4.1.2 UCC FINANCING STATEMENTS AND ASSIGNMENTS SEPARATE FROM CERTIFICATE. Deliver (i) to Pledgees such UCC financing statements and other documents executed by Pledgor as Pledgees require to perfect Pledgees' security interest in such additional capital stock and, (ii) to Pledgees, or prior to the termination of the Intercreditor Agreement to FCC, an assignment separate from certificate with respect to such capital stock in the form attached hereto as Exhibit B, executed in blank by Pledgor; 4.1.3 REPRESENTATIONS AND WARRANTIES.

Pledgor agrees that such additional capital stock shall constitute a portion of the Collateral and be subject to this Pledge Agreement in the same manner and to the same extent as the Securities pledged hereby to Pledgees on the date hereof. 5. VOTING POWER. Unless and until an Event of Default shall have occurred and is continuing, Pledgor shall be entitled to exercise all voting powers in all company matters pertaining to the Collateral or otherwise, for any purpose not inconsistent with, or in violation of, any of the Investment Agreements. 6. INTERCREDITOR AGREEMENT. The Liens granted pursuant to this Pledge Agreement are subject to the Intercreditor Agreement, which, among other things, subordinates the Lien in the Collateral granted to Pledgee hereunder to the Lien in the Collateral granted to the holders of Senior Obligations, as defined in the Intercreditor Agreement. - 3 - <Page> 7. DEFAULT AND REMEDIES. 7.1 OCCURRENCE. The occurrence of an Event of Default under the Notes shall constitute an Event of Default hereunder. 7.2 REMEDIES. If an Event of Default shall occur and be continuing, Pledgees, at their option and subject to the provisions of the Intercreditor Agreement, may: 7.2.1 REGISTRATION. Cause the Collateral to be registered in its name or in the name of its nominee; 7.2.2 VOTING POWER. Exercise all voting powers pertaining to the Collateral and otherwise act with respect thereto as though Pledgees were the owner thereof; 7.2.3 DISTRIBUTIONS. Receive all dividends and distributions of any kind whatsoever on all or any part of the Collateral; 7.2.4 COLLECTION; CONVERSION. Exercise any and all rights of collection, conversion or exchange, and any and all other rights, privileges, options or powers of Pledgor pertaining or relating to the Collateral; 7.2.5 SALE OF COLLATERAL. Subject to any applicable state or federal securities laws, sell, assign and deliver the whole, or from time to time, any part of the Collateral at any broker's board or at any private sale or at public auction, with or without demand for performance or advertisement of the time or place of sale or adjournment thereof or otherwise, and free from any right of redemption (all of which hereby expressly are waived by Pledgor) for cash, for credit or for other property, for immediate or future delivery, and for such price and on such terms as Pledgees in their sole discretion may determine; 7.2.6 OTHER REMEDIES. Exercise any other remedy specifically granted under this Pledge Agreement or now or hereafter existing in equity, or at law, by virtue of statute or otherwise; and 7.2.7 POWER OF ATTORNEY. With respect to the actions described in each of subsections 7.2.2 and 7.2.4 above, Pledgor hereby irrevocably constitutes and appoints each Pledgee its proxy and attorney-in-fact with full power of substitution and acknowledges that the constitution and appointment of such proxy and attorney-in-fact are coupled with an interest and are irrevocable until all of Pledgor's Obligations are paid and performed in full. 7.3 AGREEMENT TO SELL COLLATERAL. For the purposes of this Section 7, an agreement to sell all or any part of the Collateral shall be treated as a sale thereof and Pledgees shall be free to carry out such sale pursuant to such agreement, and Pledgor - 4 - <Page> shall not be entitled to the return of any of the same subject thereto, notwithstanding the fact that after Pledgees shall have entered into such an agreement, all Events of Default hereunder may have been remedied or all of Pledgor's Obligations may have been paid and/or performed in full. 7.4 PLEDGEES MAY BID. At any sale made pursuant to Section 7.2 above, Pledgees may bid for and purchase, free from any right of equity or redemption on the part of Pledgor (the same hereby being waived and released by Pledgor), any part or all of the Collateral that is offered for sale, and Pledgees, upon compliance with the terms of sale, may hold, retain and dispose of such Collateral without further accountability therefor. 7.5 NO DUTY OF PLEDGEES. Pledgees shall not have any duty to exercise any of the rights, privileges, options or powers or to sell or otherwise realize upon any of the Collateral, as hereinbefore authorized, and Pledgees shall not be responsible for any failure to do so or delay in so doing. 7.6 EFFECT OF SALE. Any sale of all or any portion of the Collateral pursuant to Section 7.2 above shall operate to divest all right, title and interest of Pledgor to the Collateral which is the subject of any such sale. 7.7 SECURITIES ACT. Pledgor acknowledges that Pledgees may be unable to effect a public sale of all or a part of the Collateral by reason of certain prohibitions contained in the Securities Act, or that it may be able to do so only after delay which might adversely affect the value that might be realized upon the sale of the Collateral. Accordingly, Pledgor agrees that Pledgees, without the necessity of attempting to cause any registration of the Collateral to be effected under the Securities Act, may sell the Collateral or any part thereof in one or more private sales to a restricted group of purchasers who may be required to agree, among other things, that they are acquiring the Collateral for their own account, for investment purposes only, and not with a view toward the distribution or resale thereof. Pledgor agrees that any such private sale may be at prices or on terms less favorable to the owner of the Collateral sold than would be the case if such Collateral was sold at public sale, and that any such private sale shall not be deemed not to have been made in a commercially reasonable manner by virtue of such sale having been a private sale. 7.8 TRANSFER OF CONTROL TO OTHER PERSONS. Pledgor acknowledges and agrees that a transfer of control of the Collateral may be made to a receiver, trustee or similar official or to any purchaser of all or any part of the other Collateral hereunder, pursuant to any court order, public or private sale, judicial sale, foreclosure or the exercise of any other remedies available to Pledgees hereunder or under applicable law. 7.9 NOTICE. Pledgees shall give not less than 10 Business Days' prior written notice to Pledgor of any sale pursuant to this Section 7. Pledgor hereby agrees that such notice is commercially reasonable. - 5 - <Page> 8. PLEDGEES' OBLIGATIONS, CUSTODIAL AGREEMENT, PERFORMANCE RIGHTS, PLEDGE DOES NOT MAKE PLEDGEES SHAREHOLDERS. Neither Pledgee shall have any duty to protect, preserve or enforce rights against the Collateral other than a duty of reasonable custodial care of any such Collateral in its possession, it being understood that, prior to either Pledgee's purchase of the Collateral at any sale pursuant to Section 7 hereof, Pledgees shall (i) have no responsibility for (A) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to the Collateral, whether or not Pledgees have or are deemed to have knowledge of such matters, (B) taking any necessary steps to preserve rights against any parties with respect to the Collateral or (C) making any capital contributions or other payments on behalf of Pledgor and (ii) not be deemed to be a shareholder of the Pledged Companies unless Pledgees purchase or otherwise retain the applicable portion of the Collateral in connection with a foreclosure. 9. TERMINATION OF PLEDGE AGREEMENT. Upon the payment and performance in full of all of the Notes or the conversion in full of all of the Notes in accordance with their terms, Pledgees shall deliver to Pledgor the Collateral in its possession and this Pledge Agreement thereupon shall terminate. 10. MISCELLANEOUS. 10.1 EXERCISE OF RIGHTS. Pledgor unconditionally agrees that if an Event of Default has occurred and is continuing, Pledgees may exercise their rights and remedies hereunder prior to, concurrently with, or subsequent to the exercise by Pledgees of its rights and remedies against Pledgor or any other person or entity under any of the Investment Agreements or otherwise. The obligations of Pledgor under this Pledge Agreement shall be absolute and unconditional and shall remain in full force and effect without regard to, and shall not be released or discharged or in any way affected by: 10.1.1 AMENDMENTS. Any amendment or modification of or supplement to any of the Investment Agreements; 10.1.2 EXERCISE OR NON-EXERCISE OF RIGHTS. Any exercise or non-exercise of any right or remedy under any of the Investment Agreements, or the granting of any postponements or extensions for time of payment or other indulgences to Pledgor or any other person or entity, or the settlement or adjustment of any claim or the release or discharge or substitution of any person or entity primarily or secondarily liable with respect to any of the Investment Agreements; 10.1.3 BANKRUPTCY. The institution of any bankruptcy, insolvency, reorganization, debt arrangement, readjustment, composition, receivership or liquidation proceedings by or against Pledgor, the Pledged Companies, the Guarantors or any other person or entity; or - 6 - <Page> 10.1.4 OTHER DEFENSES. Any other circumstance which otherwise might constitute a defense to, or a discharge of, Pledgor with respect to Pledgor's Obligations. 10.2 RIGHTS CUMULATIVE. Each and every right, remedy and power granted to Pledgees hereunder shall be cumulative and in addition to any other right, remedy or power specifically granted herein or now or hereafter existing in equity, at law, by virtue of statute or otherwise and may be exercised by Pledgees, from time to time, concurrently or independently and as often and in such order as Pledgees may deem expedient. Any failure or delay on the part of either Pledgee in exercising any such right, remedy or power, or abandonment or discontinuance of steps to enforce the same, shall not operate as a waiver thereof or affect the right of either Pledgee thereafter to exercise the same, and any single or partial exercise of any such right, remedy or power shall not preclude any other or further exercise thereof or the exercise of any other right, remedy or power, and no such failure, delay, abandonment or single or partial exercise of rights of Pledgees hereunder shall be deemed to establish a custom or course of dealing or performance among the parties hereto. 10.3 MODIFICATION. Any modification or waiver of any provision of this Pledge Agreement, or any consent to any departure by Pledgor therefrom, shall not be effective in any event unless the same is in writing and signed by both Pledgees and Pledgor and then such modification, waiver or consent shall be effective only in the specific instance and for the specific purpose given. Any notice to or demand on Pledgor in any event not specifically required of Pledgees hereunder shall not entitle Pledgor to any other or further notice or demand in the same, similar or other circumstances unless specifically required hereunder. 10.4 FURTHER ASSURANCES. Pledgor agrees that at any time, and from time to time, after the execution and delivery of this Pledge Agreement, Pledgor, upon the request of either Pledgee, promptly will execute and deliver such further documents and do such further acts and things as either Pledgee reasonably may request in order to effect fully the purposes of this Pledge Agreement and to subject to the security interest created hereby any Collateral intended by the provisions hereof to be covered hereby. Pledgor and both Pledgees acknowledge their intent that, upon the occurrence of an Event of Default, Pledgees shall receive, to the fullest extent permitted by law and governmental policy, all rights necessary or desirable to obtain, use or sell the Collateral, and to exercise all remedies available to Pledgees under the Investment Agreements, the Uniform Commercial Code or other applicable law. 10.5 PRESERVATION OF COLLATERAL. Pledgor agrees that it will warrant, preserve, maintain and defend, at the expense of Pledgor, the right, title and interest of Pledgees in and to the Collateral and all right, title and interest represented thereby against all claims, charges and demands of all persons or entities whomsoever which are based on a breach of Pledgor's Obligations hereunder. - 7 - <Page> 10.6 NOTICES.

Pledgor irrevocably waives the defense of an inconvenient forum to the maintenance of such suit or proceeding. Pledgor further agrees that service of process upon Pledgor mailed by the first class mail shall be deemed in every respect effective service of process upon Pledgor in any suit or proceeding arising hereunder. Nothing herein shall affect either Pledgee's right to serve process in any other manner permitted by law. The parties hereto agree that a final non-appealable judgment in any such suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on such judgment or in any other lawful manner. 10.8 WAIVER OF JURY TRIAL. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, PLEDGOR AND PLEDGEES HEREBY WAIVE AND COVENANT THAT THEY WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE, CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS PLEDGE AGREEMENT OR ANY OTHER INVESTMENT AGREEMENT OR THE SUBJECT MATTER HEREOF OR THEREOF OR ANY OBLIGATION HEREUNDER OR THEREUNDER OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PLEDGEES OR PLEDGOR OR ANY OF THEM IN CONNECTION WITH ANY OF THE ABOVE, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE. PLEDGOR AND PLEDGEES ACKNOWLEDGE THAT THE PROVISIONS OF THIS SECTION 10.8 CONSTITUTE A MATERIAL INDUCEMENT UPON WHICH EACH OF PLEDGOR AND PLEDGEES HAVE RELIED, ARE RELYING AND WILL RELY IN ENTERING INTO THIS PLEDGE AGREEMENT AND THE OTHER INVESTMENT AGREEMENTS. Either Pledgee or Pledgor may file an original counterpart or a copy of this Section 10.8 with any court as written evidence of the consent of the parties hereto to the waiver of their respective right to trial by jury. 10.9 SEVERABILITY. In the event that any provision of this Pledge Agreement is deemed to be invalid by reason of the operation of any law, or by reason of the interpretation placed thereon by any court, the validity, legality and enforceability of the remaining terms and provisions of this Pledge Agreement shall not in any way be - 8 - <Page> affected or impaired thereby, all of which shall remain in full force and effect, and the affected term or provision shall be modified to the minimum extent permitted by law so as to achieve most fully the intention of this Pledge Agreement. 10.10 SUCCESSORS AND ASSIGNS.
