      2. Pledge; Grant of Security Interest. Pledgor hereby delivers to the PBGC
all the Pledged Stock and hereby grants to the PBGC a first security interest in

performance when due (whether at the stated maturity, by acceleration or
otherwise) of the Secured Obligations.

      3. Stock Powers; Endorsements. Concurrently with the delivery to the PBGC
of each certificate representing one or more shares of Pledged Stock to the
PBGC, the Pledgor of such Pledged Stock shall deliver an undated stock power
covering such certificate, duly executed in blank by such Pledgor with, if the
PBGC so requests, signature guaranteed.

      4. Representations and Warranties. Pledgor represents and warrants that:

            1. It has the corporate power and authority and the legal right to
      execute and deliver, to perform its obligations under, and to grant the
      lien on the Collateral pursuant to, this Agreement and has taken all
      necessary corporate action to authorize its execution, delivery and
      performance of, and grant of the lien on the Collateral pursuant to, this
      Agreement.

            2. This Agreement constitutes a legal, valid and binding obligation
      of Pledgor, enforceable in accordance with its terms, and upon delivery to
      the PBGC of the stock certificates evidencing the Pledged Stock, the lien
      created pursuant to this Agreement will constitute a valid, perfected
      first priority security interest in the Collateral, enforceable in
      accordance with its terms against all creditors of the Pledgor and any
      Persons purporting to purchase any Collateral from such Pledgor, except in
      each case as enforceability may be affected by bankruptcy, insolvency,
      fraudulent conveyance, reorganization, moratorium and other similar laws
      relating to or affecting creditors' rights generally, general equitable
      principles (whether considered in a proceeding in equity or at law) and an
      implied covenant of good faith and fair dealing.

            3. The execution, delivery and performance of this Agreement will
      not violate any provision of any law of the United States or any state
      thereof, or contractual obligation of Pledgor and will not result in the
      creation or imposition of any lien on any of the properties or revenues of
      such Pledgor pursuant to any law or contractual obligation of Pledgor,
      except the security interest created by this Agreement.

            4. No consent or authorization of, filing with, or other act by or
      in respect of, any arbitrator or governmental authority of the United
      States or any state thereof and no consent of any other Person (including,
      without limitation, any stockholder or creditor of Pledgor), is required
      in connection with the execution, delivery, performance, validity or
      enforceability of this Agreement.

            5. No litigation, investigation or proceeding of or before any
      arbitrator or governmental authority is pending or, to the knowledge of
      Pledgor, threatened by or against Pledgor or against any of its properties
      or revenues with respect to this Agreement or any of the transactions
      contemplated hereby.



            6. The shares of Pledged Stock set forth on Schedule 1 hereto
      opposite the name of each Issuer constitute the percentage of such issued
      and outstanding shares set forth opposite the name of such Issuer on such
      Schedule.

            7. All the shares of the Pledged Stock have been duly and validly
      issued and are fully paid and nonassessable.

            8. Pledgor is the record and beneficial owner of, and has good and
      marketable title to, the Pledged Stock, free of any and all liens or
      options in favor of, or claims of, any other person, except the security
      interest created by this Agreement.

      5. Covenants. Pledgor covenants and agrees with the PBGC from and after
the date of this Agreement until the Secured Obligations are paid and performed
in full:

            1. If such Pledgor shall, as a result of its ownership of the
      Pledged Stock, become entitled to receive or shall receive any stock
      certificate (including, without limitation, any certificate representing a
      stock dividend or a distribution in connection with any reclassification,
      increase or reduction of capital or any certificate issued in connection
      with any reorganization), option or rights, whether in addition to, in
      substitution of, as a conversion of, or in exchange for any shares of the
      Pledged Stock, or otherwise in respect thereof, such Pledgor shall accept
      the same as the agent of the PBGC, hold the same in trust for the PBGC,
      and deliver the same forthwith to the PBGC in the exact form received,
      duly indorsed by Pledgor to the PBGC, if required, together with an
      undated stock power covering such certificate duly executed in blank by
      Pledgor and with, if the PBGC so requests, signature guaranteed, to be
      held by the PBGC, subject to the terms hereof, as additional collateral
      security for the Secured Obligations, provided that the Pledgor shall be
      entitled to sell or otherwise dispose of such stock and utilize the
      proceeds of such sale or disposition to pay the Secured Obligations. Any
      sums paid upon or in respect of the Pledged Stock upon the liquidation or
      dissolution of any Issuer shall be paid over to the PBGC to be held by it
      hereunder as additional collateral security for the Secured Obligations,
      and in case any distribution of capital shall be made on or in respect of
      the Pledged Stock or any property shall be distributed upon or with
      respect to the Pledged Stock pursuant to the recapitalization or
      reclassification of the capital of any Issuer or pursuant to the
      reorganization thereof, the property so distributed shall be delivered to
      the PBGC to be held by it hereunder as additional collateral security for
      the Secured Obligations. If any sums of money or property so paid or
      distributed in respect of the Pledged Stock shall be received by Pledgor,
      it shall, until such money or property is paid or delivered to the PBGC,
      hold such money or property in trust, segregated from other funds of
      Pledgor, as additional collateral security for the Secured Obligations.

            2. Without the prior written consent of the PBGC, such Pledgor will
      not vote to enable, or take any other action to permit, any Issuer to
      issue any stock or other equity securities of any nature or to issue any
      other securities convertible into or granting the right to purchase or
      exchange for any stock or other equity securities of any nature of any
      Issuer, sell, assign, transfer, exchange, or otherwise dispose of, or
      grant any option with respect to, the Collateral, create, incur or permit
      to exist any lien or option in favor of, or any claim of any person with
      respect to, any of the Collateral, or any interest therein, except for the
      security interests created by this Agreement or enter into any agreement
      or undertaking restricting the right or ability of Pledgor or the PBGC to
      vote, sell, assign or transfer any of the Collateral.

            3. Pledgor shall maintain the security interest created by this
      Agreement as a first, perfected security interest and shall defend such
      security interest against claims and demands of all persons whomsoever. At
      any time and from time to time, upon the written request of the PBGC, and
      at the sole expense of Pledgor, it will promptly and duly execute and
      deliver such further instruments and documents and take such further
      actions as the PBGC may reasonably request for the purposes of obtaining
      or preserving the full benefits of this Agreement and of the rights and
      powers herein granted. If any amount payable under or in connection with
      any of the Collateral shall be or become evidenced by any promissory note,
      other instrument or chattel paper, such note, instrument or chattel paper
      shall be immediately delivered to the PBGC, duly endorsed in a manner
      satisfactory to the PBGC, to be held as Collateral pursuant to this
      Agreement.



                  4. Pledgor shall pay, and save the PBGC, the Co-Agents and the
      Lenders harmless from, any and all liabilities with respect to, or
      resulting from any delay in paying, any and all stamp, excise, sales or
      other taxes which may be payable or determined to be payable with respect
      to any of the Collateral or in connection with any of the transactions
      contemplated by this Agreement.

      6. Cash Dividends and Voting Rights; Payments of Principal and Interest.
Unless an Event of Default shall have occurred and be continuing and the PBGC
shall have given notice to Pledgor of the PBGC's intent to exercise its
corresponding rights pursuant to Section 7 below, Pledgor shall be permitted to
receive all cash dividends paid in the normal course of business of the Issuers
in respect of the Pledged Stock and to exercise all voting and corporate rights
with respect to the Pledged Stock; provided, however, that no vote shall be cast
or corporate right exercised or other action taken which, in the PBGC's
reasonable judgment, would impair the Collateral or which would be inconsistent
with or result in any violation of any provision of this Agreement.

      7. Rights of the Lenders and the PBGC. All money Proceeds received by the
PBGC hereunder shall be held by the PBGC and shall continue to be held as
collateral security for all the Secured Obligations and shall not constitute
payment thereof until applied as provided in paragraph 8(a).

            1. If an Event of Default shall occur and be continuing and the PBGC
      shall give notice of its intent to exercise such rights to Pledgor, the
      PBGC shall have the right to receive any and all dividends paid in respect
      of the Pledged Stock and Pledgor shall segregate and hold in trust for the
      benefit of the PBGC any payments received by Pledgor after receipt of such
      notice and make application thereof to the Secured Obligations in such
      order as the PBGC may determine, all shares of the Pledged Stock shall be
      registered in the name of the PBGC or its nominee, and the PBGC or its
      nominee may thereafter exercise all voting, corporate and other rights
      pertaining to such shares of the Pledged Stock at any meeting of
      shareholders of any Issuer or otherwise and any and all rights of
      conversion, exchange, subscription and any other rights, privileges or
      options pertaining to such shares of the Pledged Stock as if it were the
      absolute owner thereof (including, without limitation, the right to
      exchange at its discretion any and all of the Pledged Stock upon the
      merger, consolidation, reorganization, recapitalization or other
      fundamental change in the corporate structure of any Issuer, or upon the
      exercise by Pledgor or the PBGC of any right, privilege or option
      pertaining to such shares of the Pledged Stock, and in connection
      therewith, the right to deposit and deliver any and all of the Pledged
      Stock with any committee, depositary, transfer agent, registrar or other
      designated agency upon such terms and conditions as the PBGC may
      determine), all without liability except to account for property actually
      received by it, but the PBGC shall have no duty to Pledgor to exercise any
      such right, privilege or option and shall not be responsible for any
      failure to do so or delay in so doing and the PBGC shall be entitled to,
      but shall in no event be obligated to, exercise any rights and remedies of
      the holder of any Pledged Note.



      8. Remedies. If an Event of Default shall have occurred and be continuing,
at any time at the PBGC's election, the PBGC may apply all or any part of
Proceeds in payment of the Secured Obligations as the PBGC may elect.

      9. If an Event of Default shall have occurred and be continuing, the PBGC
may exercise, in addition to all other rights and remedies granted in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Secured Obligations, all rights and remedies of a secured party
under the Code.

      10. Pledgor shall remain liable for any deficiency if the proceeds of any
sale or other disposition of Collateral are insufficient to pay the Secured
Obligations and the reasonable fees and disbursements of any attorneys employed
by the PBGC to collect such deficiency.

      11. Registration Rights; Private Sales. If the PBGC shall determine to
exercise its right to sell any or all of the Pledged Stock pursuant to paragraph
8(b) hereof, and if in the opinion of the PBGC it is necessary or advisable to
have the Pledged Stock, or that portion thereof to be sold, registered under the
provisions of the Securities Act, Pledgor will cause the Issuer thereof to
execute and deliver, and cause the directors and officers of such Issuer to
execute and deliver, all such instruments and documents, and do or cause to be
done all such other acts as may be, in the opinion of the PBGC, necessary or
advisable to register the Pledged Stock, or that portion thereof to be sold,
under the provisions of the Securities Act, use its best efforts to cause the
registration statement relating thereto to become effective and to remain
effective for a period of one year from the date of the first public offering of
the Pledged Stock, or that portion thereof to be sold, and make all amendments
thereto and/or to the related prospectus which, in the opinion of the PBGC, are
necessary or advisable, all in conformity with the requirements of the
Securities Act and the rules and regulations applicable thereto. Such Pledgor
agrees to cause each such Issuer to comply with the provisions of the securities
or "Blue Sky" laws of any and all jurisdictions which the PBGC shall designate
and to make available to its security holders, as soon as practicable, an
earnings statement (which need not be audited) which will satisfy the provisions
of the Securities Act.

      12. Pledgor recognizes that the PBGC may be unable to effect a public sale
of any or all the Pledged Stock, by reason of certain prohibitions contained in
the Securities Act and applicable state securities laws or otherwise, and may be
compelled to resort to one or more private sales thereof to a restricted group
of purchasers which will be obliged to agree, among other things, to acquire
such securities for their own account for investment and not with a view to the
distribution or resale thereof. Pledgor acknowledges and agrees that any such
private sale may result in prices and other terms less favorable than if such
sale were a public sale and, notwithstanding such circumstances, agrees that any
such private sale shall be deemed to have been made in a commercially reasonable
manner. The PBGC shall be under no obligation to delay a sale of any of the
Pledged Stock for the period of time necessary to permit the Issuer thereof to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such Issuer would agree to do so.

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



      14. Irrevocable Authorization and Instruction to Issuer. Pledgor hereby
authorizes and instructs each Issuer to comply with any instruction received by
it from the PBGC in writing that (a) states that an Event of Default has
occurred and (b) is otherwise in accordance with the terms of this Agreement,
without any other or further instructions from Pledgor, and Pledgor agrees that
each Issuer shall be fully protected in so complying.

      15. PBGC's Appointment as Attorney-in-Fact. Pledgor hereby irrevocably
constitutes and appoints the PBGC and any officer or agent of the PBGC, with
full power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of Pledgor and in the
name of Pledgor or in the PBGC's own name, from time to time in the PBGC's
discretion, but only following an Event of Default by Pledgor, for the purpose
of carrying out the terms of this Agreement, to take any and all appropriate
action and to execute any and all documents and instruments which may be
necessary or desirable to accomplish the purposes of this Agreement, including,
without limitation, any financing statements, endorsements, assignments or other
instruments of transfer.

      16. Pledgor hereby ratifies all that said attorneys shall lawfully do or
cause to be done pursuant to the power of attorney granted in paragraph 11(a) in
accordance with the terms hereof. All powers, authorizations and agencies
contained in this Agreement are coupled with an interest and are irrevocable
until this Agreement is terminated and the security interests created hereby are
released.

      17. Duty of PBGC. The PBGC's sole duty with respect to the custody,
safekeeping and physical preservation of the Collateral in its possession, under
Section 9-207 of the Code or otherwise, shall be to deal with it in the same
manner as the PBGC deals with similar securities and property for its own
account, except that the PBGC may hold the same as demand deposits. Neither the
PBGC, nor any of its respective directors, officers, employees or agents shall
be liable for failure to demand, collect or realize upon any of the Collateral
other than for gross negligence or willful misconduct in taking or refraining
from taking any action, or for any delay in doing so or shall be under any
obligation to sell or otherwise dispose of any Collateral upon the request of
Pledgor or any other person or to take any other action whatsoever with regard
to the Collateral or any part thereof.

      18. Authority of PBGC. Pledgor acknowledges that the rights and
responsibilities of the PBGC under this Agreement with respect to any action
taken by the PBGC or the exercise or non-exercise by the PBGC of any option,
voting right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall be governed by this Agreement.
The PBGC shall be conclusively presumed to be acting with full and valid
authority so to act or refrain from acting, and neither Pledgor nor any Issuer
shall be under any obligation, or entitlement, to make any inquiry respecting
such authority.

      19. Notices. Any notices, requests or other communications hereunder shall
be in writing, and shall be deemed to have been duly given when mailed by United
States registered or certified mail postage prepaid, or upon receipt if
overnight delivery service, telecopy, or telex is used, addressed as follows:

unconditionally:

            1. _____________ submits for itself and its property in any legal
      action or proceeding relating to this Agreement, or for recognition and
      enforcement of any judgment in respect thereof, to the non-exclusive
      general jurisdiction of the courts of the State of New York, the courts of
      the United States of America for the Southern District of New York, and

      brought in such courts, and waives any objection that it may now or
      hereafter have to the venue of any such action or proceeding in any such

            3. _____________ agrees that service of process in any such action
      or proceeding may be effected by mailing a copy thereof by registered or
      certified mail (or any substantially similar form of mail), postage

      Section 15;



            4. _____________ agrees that nothing herein shall affect the right

transmission from the PBGC.

      24. The PBGC shall not by any act (except by a written instrument pursuant
to paragraph 18(a) hereof), delay, indulgence, omission or otherwise be deemed
to have waived any right or remedy hereunder or to have acquiesced in any
default or Event of Default or in any breach of any of the terms and conditions
hereof. No failure to exercise, nor any delay in exercising, on the part of the
PBGC any right, power or privilege hereunder shall operate as a waiver thereof.
No single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the PBGC of any right or remedy hereunder
on any one occasion shall not be construed as a bar to any right or remedy which
the PBGC would otherwise have on any future occasion.

exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

      26. Section Headings. The section headings used in this Agreement are for
convenience of reference only and are not to affect the construction hereof or
be taken into consideration in the interpretation hereof.

      27. Successors and Assigns. This Agreement shall be binding upon the
successors and assigns of Pledgor and shall inure to the benefit of the PBGC,
and its successors and assigns, except that Pledgor may not assign or transfer
any of its rights or obligations under this Agreement without the prior written
consent of PBGC.
