Purchase Agreement
6451 S. Country Club, Suite 111

Ladies and Gentlemen:

     We refer to the Securities Purchase Agreement ("SPA") and Debentures and
related ancillary documents, dated as of December 20, 2007 ("Transaction
Documents") by and among Global Aircraft Solutions, Inc., Hamilton Aerospace
Technologies, Inc., World Jet Corporation, Hamilton Aerospace Mexico S.A. de
C.V. (collectively, the "Companies") and the Buyers referred to therein and such
undersigned Buyers and subsequent Holders thereof (collectively, the "Buyers").
Capitalized terms used and not defined herein have the meanings given to such
terms in the Transaction Documents, as applicable.

     Section 7 of the SPA sets forth the conditions precedent to the obligation
of the Buyers to purchase the Debentures under the Transaction Documents.
Notwithstanding the terms of Section 7, the parties acknowledge that the
conditions precedent identified in Schedule 1 attached hereto will not be
satisfied on or prior to December 20, 2007 (collectively, the "Post-Closing
Conditions"). The Buyers agree to waive the satisfaction of the Post-Closing
Conditions as conditions precedent to the purchase of the Debentures under the
Transaction Documents, and in consideration thereof, the Companies agree to
complete or cause to complete, as applicable, the actions required thereby on or
before the applicable completion deadline identified in Schedule 1. The
Companies agree that the failure to fully complete such actions on or before the
applicable completion deadline identified in Schedule 1 shall (i) constitute an
Event of Default under the Debentures, and (ii) automatically cause the interest
rate to be calculated at the Default Rate until such time as all Post-Closing
Conditions have been performed, satisfied, waived by all the Buyers, or
otherwise fulfilled as determined in the sole discretion of the Buyers;
provided, however, in each case, such failure shall not in any way impair the
effectiveness of the Transaction Documents.

     The Companies further agree that none of the Aircraft and/or Engines may be
sold and no monies shall be collected as deposits against the sale proceeds of
said Aircraft and/or Engines until the Deposit Account Control Agreements have
been executed and delivered by all parties thereto. Any sale by the Companies of
any Aircraft or Engines prior to the execution and delivery of the Deposit
Account Control Agreements shall be deemed an Event of Default under the
Debentures.

     Except as provided above, the Transaction Documents remain unmodified and
in full force and effect. The execution and delivery of this letter agreement by
the Buyers is a one time accommodation and shall not be deemed to create a
course of dealing or otherwise create any express or implied duty by the Buyers.
The Buyers reserve all rights and remedies available to them under the
Transaction Documents. The agreements contained herein shall be governed by, and
construed in accordance with, the law of the State of New York. This letter
agreement may be executed in any number of counterparts and by different parties
hereto in separate counterparts, each of which when so executed shall be deemed
to be an original and all of which taken together shall constitute but one and
the same agreement. This letter agreement is a Transaction Document.

     The Companies should indicate their agreement to the foregoing by signing
and returning to the Buyers a counterpart of this letter agreement.

                           [Signature Pages Following]

hereunder. The execution, delivery and performance by such Obligor of this

right to keep and maintain such Collateral in full force and effect, and there
is no proceeding involving said rights pending or, to the best knowledge of such
Obligor, threatened before any court, judicial body, administrative or
regulatory agency, arbitrator or other governmental authority.

               (e) Such Obligor shall at all times maintain its books of account
and records relating to the Collateral at its principal place of business and
its Collateral at the locations set forth on Schedule A attached hereto and may
not relocate such books of account and records or tangible Collateral unless it
delivers to the Secured Parties at least 30 days prior to such relocation (i)
written notice of such relocation and the new location thereof (which must be
within the United States) and (ii) evidence that appropriate financing
statements under the UCC and other necessary documents have been filed and
recorded and other steps have been taken to perfect the Security Interest to
create in favor of each of the Secured Parties a valid, perfected and continuing
perfected first priority lien in the Collateral.

               (f) This Agreement creates in favor of the Secured Parties a
valid security interest in the Collateral securing the payment and performance
of the Obligations and, upon making the filings described in the immediately
following sentence, a perfected first priority security interest in such
Collateral.

               (g) Such Obligor hereby authorizes each of the Secured Parties to
file one or more financing statements under the UCC, with respect to the
Security Interest with the proper filing and recording agencies in any
jurisdiction deemed proper by them.

               (h) The execution, delivery and performance of this Agreement by
such Obligor does not conflict with, or constitute a default (or an event that
with notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation (with
or without notice, lapse of time or both) of, any agreement, credit facility,
debt or other instrument (evidencing such Obligor's debt or otherwise) or other
understanding to which such Obligor is a party or by which any property or asset
of such Obligor is bound or affected. No consent (including, without limitation,
from stockholders or creditors of such Obligor) is required for such Obligor to
enter into and perform its obligations hereunder.

               (i) Such Obligor shall at all times maintain the liens and
Security Interest provided for hereunder as valid and perfected first priority
liens and Security Interests in the Collateral in favor of the Secured Parties
until this Agreement and the Security Interest hereunder shall be terminated
pursuant to Section 11 hereof. Such Obligor hereby agrees to defend the same
against any and all persons. Such Obligor shall safeguard and protect all
Collateral for the account of the Secured Parties. Such Obligor irrevocably
authorizes the Secured Parties at any time and from time to time to file in any
filing office in any jurisdiction any initial financing statement or amendment
thereto that indicates the collateral as "all assets" or "all personal property"
of such Obligor or words of similar effect and will pay the cost of filing the
same in all public offices wherever filing is, or is deemed by the Secured
Parties to be, necessary or desirable to effect the rights and obligations
provided for herein. Without limiting the generality of the foregoing, such
Obligor shall pay all fees, taxes and other amounts necessary to maintain the
Collateral and the Security Interest hereunder, and such Obligor shall obtain
and furnish to the Secured Parties from time to time, upon demand, such releases
and/or subordinations of claims and liens which may be required to maintain the
priority of the Security Interest hereunder.

               (j) Such Obligor will not transfer, pledge, hypothecate,
encumber, license (except for sales of inventory in the ordinary course of
business), sell or otherwise dispose of any of the Collateral without the prior
written consent of the Secured Parties which consent shall not be unreasonably
withheld or delayed.

               (k) Such Obligor shall keep and preserve its Equipment, Inventory
and other tangible Collateral in good condition, repair and order and shall not
operate or locate any such Collateral (or cause to be operated or located) in
any area excluded from insurance coverage.

               (l) Such Obligor shall, within three (3) days of obtaining
knowledge thereof, advise the Secured Parties promptly, in sufficient detail, of
any substantial change in the Collateral, and of the occurrence of any event
which would have a material adverse effect on the value of the Collateral or on
the Secured Parties' security interest therein.

               (m) Such Obligor shall promptly execute and deliver to the
Secured Parties such further deeds, mortgages, fixture filings, assignments,
security agreements, financing statements or other instruments, documents,
certificates and assurances and take such further action as any Secured Party
may from time to time request and may in its sole discretion deem necessary to
perfect, protect or enforce its security interest in the Collateral or any
additional collateral, including, without limitation, the execution and delivery
of separate mortgages and fixture filings, which shall be satisfactory to the
Secured Parties in their sole discretion for real or personal property interest.

               (n) Such Obligor shall permit the Secured Parties and their
representatives and agents to inspect the Collateral at any time, and to make
copies of records pertaining to the Collateral as may be requested by the
Secured Parties from time to time at the Obligor's expense (i) so long as such
inspections do not exceed four (4) inspections in any twelve (12) months period,
or (ii) upon the occurrence and during the continuance of an Event of Default;
otherwise such inspections shall be made at the Secured Parties' own cost and
expense.

               (o) Such Obligor shall take all steps reasonably necessary to
diligently pursue and seek to preserve, enforce and collect any rights, claims,
causes of action and accounts receivable in respect of the Collateral.

               (p) Such Obligor shall within three (3) Business Days notify the
Secured Parties in sufficient detail upon becoming aware of any attachment,
garnishment, execution or other legal process levied against any Collateral and
of any other information received by such Obligor that may materially affect the
value of the Collateral, the Security Interest or the rights and remedies of the
Secured Parties hereunder.

               (q) All information heretofore, herein or hereafter supplied to
the Secured Parties by or on behalf of such Obligor with respect to the
Collateral is accurate and complete in all material respects as of the date
furnished.

               (r) Such Obligor shall, and cause it subsidiaries to, at all
times preserve and keep in full force and effect their respective valid
existence and good standing and any rights and franchises material to their
businesses.

               (s) Such Obligor will not change its name, corporate structure,
or identity, or add any new fictitious name unless it provides at least thirty
(30) Business Days prior written notice to the Secured Parties of such change
and, at the time of such written notification, such Obligor provides any
financing statements or fixture filings necessary to perfect and continue
perfected the perfected first priority Security Interest granted and evidenced
by the Security Documents.

               (t) Such Obligor may not consign any of its Inventory or sell any
of its Inventory on bill and hold, sale or return, sale on approval, or other
conditional terms of sale without the consent of the Secured Parties which shall
not be unreasonably withheld.

               (u) Such Obligor may not relocate its chief executive office to a
new location without providing thirty (30) days prior written notification
thereof to the Secured Parties and so long as, at the time of such written
notification, such Obligor provides any financing statements or fixture filings
necessary to perfect and continue perfected the perfected first priority
Security Interest granted and evidenced by the Security Documents.

               (v) Such Obligor's exact legal name and jurisdiction of
organization is set forth in the introduction paragraph of this Agreement.

                    (ii) in addition, all other steps necessary or advisable
under any Applicable Law to be taken in order to perfect the first priority Lien
and security interest granted free from adverse claims hereunder shall be taken
by or on behalf of each Obligor, including without limitation, any notation on
any certificate or instrument representing the Pledged Equity and any notation
on any share register or similar document or instrument;

                    (iii) upon the delivery to the Lead Secured Party of

                    (iv) Schedules D and E to this Agreement with respect to the
Pledged Corporations are true and correct and complete in all material respects;

as applicable, in the same form as so received (with any necessary endorsement).

                    (F) Subject to the provisions of Section 5 hereof, upon the
occurrence and during the continuance of an Event of Default, (i) all voting and

               (e) Any Security Document or any material term thereof shall

               (f) Any Lien against the Collateral intended to be created by any
Security Document shall at any time be invalidated, subordinated or otherwise
cease to be in full force and effect, for whatever reason, or any security
interest purported to be created by any Security Document shall cease to be, or

accordance with the terms of this Agreement or such Security Documents); or

               (g) If any provision of this Agreement shall at any time for any
reason be declared to be null and void, or the validity or enforceability hereof
shall be contested by an Obligor, or a proceeding shall be commenced by an
Obligor, or by any governmental authority having jurisdiction over such Obligor,
seeking to establish the invalidity or unenforceability thereof, or an Obligor
shall deny that such Obligor has any liability or obligation purported to be
created under this Agreement.

          (5) DUTY TO HOLD IN TRUST. Upon the occurrence of any Event of Default
and at any time thereafter, the Obligors shall, upon receipt of any revenue,
income or other sums subject to the Security Interest, whether payable pursuant
to the Debentures or otherwise, or of any check, draft, note, trade acceptance
or other instrument evidencing an obligation to pay any such sum, hold the same
in trust for the Secured Parties and shall forthwith endorse and transfer any
such sums or instruments, or both, to the Secured Parties (pro rata in
accordance with the principal amount of Debentures held by each) for application
to the satisfaction of the Obligations.

          (6) RIGHTS AND REMEDIES UPON DEFAULT. Upon the occurrence of any Event
of Default and at any time thereafter, each Secured Party shall have the right
to exercise all of the remedies conferred hereunder and under the Debentures,
and each Secured Party shall have all the rights and remedies of a secured party
under the UCC; provided that during the Standstill Period, the Secured Party

Collateral not constituting Pledged Equity; and provided further that the
Obligors shall have the right to cure any Event of Default during the Standstill
Period subject to the Secured Parties' prior exercise of remedies and

he Secured Obligations. Without limitation, each Secured Party shall have the
following rights and powers:

               (a) The Lead Secured Party shall have the right to take
possession of the Collateral and, for that purpose, enter, with the aid and
assistance of any person, any premises where the Collateral, or any part
thereof, is or may be placed and remove the same, and the Obligors shall
assemble the Collateral and make it available to the Lead Secured Party at
places which the Lead Secured Party shall reasonably select, whether at the
Obligors' premises or elsewhere, and make available to the Lead Secured Party,
without rent, all of the Obligors' respective premises and facilities for the
purpose of the Lead Secured Party taking possession of, removing or putting the
Collateral in saleable or disposable form.

                                       11
<PAGE>

               (b) The Lead Secured Party shall have the right to operate the
business of the Obligors using the Collateral and shall have the right to
assign, sell, lease or otherwise dispose of and deliver all or any part of the
Collateral, at public or private sale or otherwise, either with or without
special conditions or stipulations, for cash or on credit or for future
delivery, in such parcel or parcels and at such time or times and at such place
or places, and upon such terms and conditions as the Lead Secured Party may deem
commercially reasonable, all without (except as shall be required by applicable
statute and cannot be waived) advertisement or demand upon or notice to the
Obligors or right of redemption of the Obligors, which are hereby expressly
waived. Upon each such sale, lease, assignment or other transfer of Collateral,
the Lead Secured Party may, unless prohibited by applicable law which cannot be
waived, purchase all or any part of the Collateral being sold, free from and
discharged of all trusts, claims, right of redemption and equities of the
Obligors, which are hereby waived and released.

          (7) APPLICATIONS OF PROCEEDS. The proceeds of any such sale, lease or
other disposition of the Collateral hereunder shall be applied first, to the
expenses of retaking, holding, storing, processing and preparing for sale,
selling, and the like (including, without limitation, any taxes, fees and other
costs incurred in connection therewith) of the Collateral, second, to the
attorneys' fees and expenses incurred by the Lead Secured Party in enforcing its
rights hereunder and in connection with collecting, storing and disposing of the
Collateral, and then to satisfaction of the Obligations to each Secured Party,
and to the payment of any other amounts required by applicable law, after which
the Secured Parties shall pay to the Obligor any surplus proceeds. If, upon the
sale, license or other disposition of the Collateral, the proceeds thereof are
insufficient to pay all amounts to which the Secured Parties are legally
entitled, the Obligors will be liable for the deficiency, together with interest
thereon, at the rate of 25% per annum or the lesser amount permitted by
applicable law (the "Default Rate"), and the reasonable fees of any attorneys
employed by the Lead Secured Party to collect such deficiency. To the extent
permitted by applicable law, each Obligor waives all claims, damages and demands
against the Secured Parties arising out of the repossession, removal, retention
or sale of the Collateral, unless due to the gross negligence or willful
misconduct of the Secured Parties. All proceeds hereof or payments under any of
the Transaction Documents shall apply to the Secured Parties on a pro-rata
basis, in accordance with principal amount of the Debentures outstanding at the
time of such payment.

          (8) COSTS AND EXPENSES. The Obligors agree to pay all reasonable
out-of-pocket fees, costs and expenses incurred in connection with any filing
required hereunder, including without limitation, any financing statements
pursuant to the UCC, continuation statements, partial releases and/or
termination statements related thereto or any expenses of any searches
reasonably required by any Secured Party. The Obligors shall also pay all other
claims and charges which in the reasonable opinion of the Lead Secured Party
might prejudice, imperil or otherwise affect the Collateral or the Security
Interest therein. The Obligors will also, upon demand, pay to the Lead Secured
Party the amount of any and all reasonable expenses, including the reasonable
fees and expenses of its counsel and of any experts and agents, which the Lead
Secured Party may incur in connection with (i) the enforcement of this
Agreement, (ii) the custody or preservation of, or the sale of, collection from,
or other realization upon, any of the Collateral, or (iii) the exercise or
enforcement of any of the rights of the Secured Parties under the Debentures.
Until so paid, any fees payable hereunder shall be added to the principal amount
of the Debentures and shall bear interest at the Default Rate.

                                       12
<PAGE>

          (9) RESPONSIBILITY FOR COLLATERAL. The Obligors assume all liabilities
and responsibility in connection with all Collateral, and the Obligations shall
in no way be affected or diminished by reason of the loss, destruction, damage
or theft of any of the Collateral or its unavailability for any reason.

          (10) SECURITY INTEREST ABSOLUTE. All rights of each Secured Party and
all Obligations of the Obligors hereunder, shall be absolute and unconditional,
irrespective of: (a) any lack of validity or enforceability of this Agreement,
the Debentures or any agreement entered into in connection with the foregoing,
or any portion hereof or thereof; (b) any change in the time, manner or place of
payment or performance of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Debentures or any other agreement entered into in connection with the
foregoing; (c) any exchange, release or nonperfection of any of the Collateral,
or any release or amendment or waiver of or consent to departure from any other
collateral for, or any guaranty, or any other security, for all or any of the
Obligations; (d) any action by the Lead Secured Party to obtain, adjust, settle
and cancel in its sole discretion any insurance claims or matters made or
arising in connection with the Collateral; or (e) any other circumstance which
might otherwise constitute any legal or equitable defense available to the
Obligors, or a discharge of all or any part of the Security Interest granted
hereby. Until the Obligations shall have been paid and performed in full, the
rights of each Secured Party shall continue even if the Obligations are barred
for any reason, including, without limitation, the running of the statute of
limitations or bankruptcy. Each Obligor expressly waives presentment, protest,
notice of protest, demand, notice of nonpayment and demand for performance. In
the event that at any time any transfer of any Collateral or any payment
received by any Secured Party hereunder shall be deemed by final order of a
court of competent jurisdiction to have been a voidable preference or fraudulent
conveyance under the bankruptcy or insolvency laws of the United States, or
shall be deemed to be otherwise due to any party other than any Secured Party,
then, in any such event, the Obligors' obligations hereunder shall survive
cancellation of this Agreement, and shall not be discharged or satisfied by any
prior payment thereof and/or cancellation of this Agreement, but shall remain a
valid and binding obligation enforceable in accordance with the terms and
provisions hereof. Each Obligor waives all right to require a Secured Party to
proceed against any other person or to apply any Collateral which such Secured
Party may hold at any time, or to marshal assets, or to pursue any other remedy.
Each Obligor waives any defense arising by reason of the application of the
statute of limitations to any obligation secured hereby.

          (11) TERM OF AGREEMENT. This Agreement and the Security Interest shall
terminate on the date on which all payments under the Debentures have been made
in full or have been satisfied and all other Obligations have been paid or
discharged. Upon such termination, each Secured Party, at the request and at the
expense of the Obligors, will join in executing any termination statement with
respect to any financing statement executed and filed pursuant to this
Agreement.

          (12) POWER OF ATTORNEY, FURTHER ASSURANCES.

               (a) Each Obligor authorizes the Lead Secured Party, and does
hereby make, constitute and appoint the Lead Secured Party and its respective
officers, agents, successors or assigns with full power of substitution, as such
Obligor's true and lawful attorney-in-fact, with power, in the name of the Lead
Secured Party or such Obligor, after the occurrence and during the continuance
of an Event of Default, (i) to endorse any note, checks, drafts, money orders or
other instruments of payment (including payments payable under or in respect of
any policy of insurance) in respect of the Collateral that may come into
possession of the Secured Party; (ii) to sign and endorse any financing
statement pursuant to the UCC or any invoice, freight or express bill, bill of
lading, storage or warehouse receipts, drafts against Obligors, assignments,
verifications and notices in connection with accounts, and other documents
relating to the Collateral; (iii) to pay or discharge taxes, liens, security
interests or other encumbrances at any time levied or placed on or threatened
against the Collateral; (iv) to demand, collect, receipt for, compromise, settle
and sue for monies due in respect of the Collateral; and (v) generally, to do,
at the option of the Lead Secured Party, and at the expense of such Obligor, at
any time, or from time to time, all acts and things which the Lead Secured Party
deem necessary to protect, preserve and realize upon the Collateral and the
Security Interest granted therein in order to effect the intent of this
Agreement and the Debentures all as fully and effectually as such Obligor might
or could do; and such Obligor hereby ratifies all that said attorney shall
lawfully do or cause to be done by virtue hereof. This power of attorney is
coupled with an interest and shall be irrevocable for the term of this Agreement
and thereafter as long as any of the Obligations shall be outstanding.

               (b) On a continuing basis, each Obligor will make, execute,
acknowledge, deliver, file and record, as the case may be, with the proper
filing and recording agencies in any jurisdiction, including, without
limitation, the jurisdictions indicated on Schedule B attached hereto, all such
instruments, and take all such action as may reasonably be deemed necessary or
advisable, or as reasonably requested by the Lead Secured Party, to perfect the
Security Interest granted hereunder and otherwise to carry out the intent and
purposes of this Agreement, or for assuring and confirming to the Lead Secured
Party the grant or perfection of a perfected first priority security interest in
all the Collateral under the UCC.

               (c) Each Obligor hereby irrevocably appoints the Lead Secured
Party as such Obligor's attorney-in-fact, with full authority in the place and
stead of such Obligor and in the name of such Obligor, from time to time in the
Lead Secured Party's discretion, to take any action and to execute any
instrument which the Lead Secured Party may deem necessary or advisable to
accomplish the purposes of this Agreement, including the filing, in its sole
discretion, of one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral without the signature of such Obligor
where permitted by law.

          (13) NOTICES. All notices, requests, demands and other communications
hereunder shall be subject to the notice provision of the applicable Securities
Purchase Agreement.

                                       14
<PAGE>

          (14) OTHER SECURITY. To the extent that the Obligations are now or
hereafter secured by property other than the Collateral or by the guarantee,
endorsement or property of any other person, firm, corporation or other entity,
then the Lead Secured Party shall have the right, in its sole discretion, to
pursue, relinquish, subordinate, modify or take any other action with respect
thereto, without in any way modifying or affecting any Secured Party's rights
and remedies hereunder.

          (15) BEST EFFORT FOR LICENSED COLLATERAL. Notwithstanding any other
provision contained herein or any of the other Transaction Documents, upon the
occurrence of an Event of Default, each Obligor hereby agrees that with respect
to any part of the Collateral which may require the consent of any third party
or third parties in order for such Obligor to transfer and/or convey its
interest in and to such Collateral to the Lead Secured Party, as may be required
in accordance herewith, such Obligor agrees to and shall use its best efforts to
obtain such consents or approvals in as expedient manner as possible.

          (16) AGENCY.

               (a) Appointment. The Secured Parties by their acceptance of the
benefits of this Agreement, hereby designate Victory Park Master Fund, Ltd.
("Lead Secured Party") as the Lead Secured Party to act as specified herein.
Each Secured Party shall be deemed irrevocably to authorize the Lead Secured
Party to take such action on its behalf under the provisions of the Agreement
and any other Transaction Document (as such term is defined in the Securities
Purchase Agreement) and to exercise such powers and to perform such duties
hereunder and thereunder as are specifically delegated to or required of the
Lead Secured Party by the terms hereof and thereof and such other powers as are
reasonably incidental thereto. The Lead Secured Party may perform any of its
duties hereunder by or through its agents or employees.

               (b) Nature of Duties. The Lead Secured Party shall have no duties
or responsibilities except those expressly set forth herein. Neither the Lead
Secured Party nor any of its partners, members, shareholders, officers,
directors, employees or agents shall be liable for any action taken or omitted
by it as such hereunder or in connection herewith, be responsible for the
consequence of any oversight or error of judgment or answerable for any loss,
unless caused solely by its or their gross negligence or willful misconduct as
determined by a final judgment (not subject to further appeal) of a court of
competent jurisdiction. The duties of the Lead Secured Party shall be mechanical
and administrative in nature; the Lead Secured Party shall not have by reason of
this Agreement or any other Transaction Document a fiduciary relationship in
respect of any Obligor or any Secured Party; and nothing in this Agreement or
any other Transaction Document, expressed or implied, is intended to or shall be
so construed as to impose upon the Lead Secured Party any obligations in respect
of this Agreement or any other Transaction Document except as expressly set
forth herein and therein.

               (c) Lack of Reliance on the Lead Secured Party. Independently and
without reliance upon the Lead Secured Party, each Secured Party, to the extent
it deems appropriate, has made and shall continue to make (i) its own
independent investigation of the financial condition and affairs of the Company

                                       15
<PAGE>

and its subsidiaries in connection with such Secured Party's investment in the
Company, the creation and continuance of the Obligations, the transactions
contemplated by the Transaction Documents, and the taking or not taking of any
action in connection therewith, and (ii) its own appraisal of the
creditworthiness of the Obligors and their subsidiaries, and of the value of the
Collateral from time to time, and the Lead Secured Party shall have no duty or
responsibility, either initially or on a continuing basis, to provide any
Secured Party with any credit, market or other information with respect thereto,
whether coming into its possession before any Obligations are incurred or at any
time or times thereafter. The Lead Secured Party shall not be responsible to any
Obligor or any Secured Party for any recitals, statements, information,
representations or warranties herein or in any document, certificate or other
writing delivered in connection herewith, or for the execution, effectiveness,
genuineness, validity, enforceability, perfection, collectibility, priority or
sufficiency of the Agreement or any other Transaction Document, or for the
financial condition of any Obligor or the value of any of the Collateral, or be
required to make any inquiry concerning either the performance or observance of
any of the terms, provisions or conditions of the Agreement or any other
Transaction Document, or the financial condition of the Obligors, or the value
of any of the Collateral, or the existence or possible existence of any default
or Event of Default under the Agreement, the Debentures or any of the other
Transaction Documents.

               (d) Certain Rights of the Lead Secured Party. Subject to this
Agreement, the Lead Secured Party shall have the right to take any action with
respect to the Collateral, on behalf of all of the Secured Parties. To the
extent practical, the Lead Secured Party shall request instructions from the
Secured Parties with respect to any material act or action (including failure to
act) in connection with the Agreement or any other Transaction Document, and
shall be entitled to act or refrain from acting in accordance with the
instructions of Secured Parties that are the Required Holders; if such
instructions are not provided despite the Lead Secured Party's request therefor,
the Lead Secured Party shall be entitled to refrain from such act or taking such
action, and if such action is taken, shall be entitled to appropriate
indemnification from the Secured Parties in respect of actions to be taken by
the Lead Secured Party; and the Lead Secured Party shall not incur liability to
any person or entity by reason of so refraining. Without limiting the foregoing,
(a) no Secured Party shall have any right of action whatsoever against the Lead
Secured Party as a result of the Lead Secured Party acting or refraining from
acting hereunder in accordance with the terms of the Agreement or any other
Transaction Document, and the Obligors shall have no right to question or
challenge the authority of, or the instructions given to, the Lead Secured Party
pursuant to the foregoing and (b) the Lead Secured Party shall not be required
to take any action which the Lead Secured Party believes (i) could reasonably be
expected to expose it to personal liability or (ii) is contrary to this
Agreement, the Transaction Documents or applicable law.

               (e) Reliance. The Lead Secured Party shall be entitled to rely,
and shall be fully protected in relying, upon any writing, resolution, notice,
statement, certificate, telex, teletype or telecopier message, cablegram,
radiogram, order or other document or telephone message signed, sent or made by
the proper person or entity, and, with respect to all legal matters pertaining
to the Agreement and the other Transaction Documents and its duties thereunder,
upon advice of counsel selected by it and upon all other matters pertaining to
this Agreement and the other Transaction Documents and its duties thereunder,
upon advice of other experts selected by it. Anything to the contrary
notwithstanding, the Lead Secured Party shall have no obligation whatsoever to
any Secured Party to assure that the Collateral exists or is owned by the
Obligors or is cared for, protected or insured or that the liens granted
pursuant to the Agreement have been properly or sufficiently or lawfully
created, perfected, or enforced or are entitled to any particular priority.

                                       16
<PAGE>

               (f) Indemnification. To the extent that the Lead Secured Party is
not reimbursed and indemnified by the Obligors, the Secured Parties will jointly
and severally reimburse and indemnify the Lead Secured Party, in proportion to
principal amounts of Debentures outstanding held at such time, from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Lead
Secured Party in performing its duties hereunder or under the Agreement or any
other Transaction Document, or in any way relating to or arising out of the
Agreement or any other Transaction Document except for those determined by a
final judgment (not subject to further appeal) of a court of competent
jurisdiction to have resulted solely from the Lead Secured Party's own gross
negligence or willful misconduct. Prior to taking any action hereunder as Lead
Secured Party, the Lead Secured Party may require each Secured Party to deposit
with it sufficient sums as it determines in good faith is necessary to protect
the Lead Secured Party for costs and expenses associated with taking such
action.

               (g) Resignation by the Lead Secured Party.

                    (i) The Lead Secured Party may resign from the performance
of all its functions and duties under the Agreement and the other Transaction
Documents at any time by giving 30 days' prior written notice (as provided in
this Agreement) to the Obligors and the Secured Parties. Such resignation shall
take effect upon the appointment of a successor Lead Secured Party pursuant to
clauses (ii) and (iii) below.

                    (ii) Upon any such notice of resignation, the Secured
Parties, acting by the Required Holders, shall appoint a successor Lead Secured
Party hereunder.

                    (iii) If a successor Lead Secured Party shall not have been
so appointed within said thirty (30) day notice period, the Lead Secured Party
shall then appoint a successor Lead Secured Party who shall serve as Lead
Secured Party until such time, if any, as the Secured Parties appoint a
successor Lead Secured Party as provided above. If a successor Lead Secured
Party has not been appointed within such thirty (30) day notice period, the Lead
Secured Party may petition any court of competent jurisdiction or may interplead
the Obligors and the Secured Parties in a proceeding for the appointment of a
successor Lead Secured Party, and all fees, including, but not limited to,
extraordinary fees associated with the filing of interpleader and expenses
associated therewith, shall be payable by the Obligors on demand.

               (h) Rights with respect to Collateral. Each Secured Party agrees
with all other Secured Parties and the Lead Secured Party (i) that it shall not,
and shall not attempt to, exercise any rights with respect to its Security
Interest in the Collateral, whether pursuant to any other agreement or otherwise
(other than pursuant to this Agreement), or take or institute any action against
the Lead Secured Party or any of the other Secured Parties in respect of the

                                       17
<PAGE>

Collateral or its rights hereunder (other than any such action arising from the
breach of this Agreement) and (ii) that such Secured Party has no other rights
with respect to the Collateral other than as set forth in this Agreement and the
other Transaction Documents. Upon the acceptance of any appointment as Lead
Secured Party hereunder by a successor Lead Secured Party, such successor Lead
Secured Party shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Lead Secured Party and the
retiring Lead Secured Party shall be discharged from its duties and obligations
under the Agreement. After any retiring Lead Secured Party's resignation or
removal hereunder as Lead Secured Party, the provisions of the Agreement shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Lead Secured Party.

               (i) The Lead Secured Party in its Individual Capacity. The Lead
Secured Party and its affiliates may purchase debentures from, make loans to,
issue letters of credit for the account of, accept deposits from and generally
engage in any kind of lending or other business with the any party and its
affiliates as though the Lead Secured Party was not the Lead Secured Party
hereunder. With respect to any loans, purchases of debentures or issuances of
credit, if any, made by the Lead Secured Party in its capacity as a Holder, the
Lead Secured Party in its capacity as a Secured Party shall have the same rights
and powers under this Agreement and the other Security Documents as any other
Secured Parties and may exercise the same as though it were not the Lead Secured
Party, and the terms "Secured Party" or "Secured Parties" shall include the Lead
Secured Party in its capacity as a Secured Party.

               (j) All proceeds from the sale of Collateral hereunder shall be
paid (i) first, to the Holders of Senior Debt on a pro-rata basis per the
principal amounts outstanding under the Debentures until the Obligations owing
to the Holders of Senior Debt are paid in cash in full; and (ii) then to the
Holder of the Junior Debt for the repayment of the Obligations owing to the
Holder of Junior Debt.

          (17) MISCELLANEOUS.

               (a) No course of dealing between the Obligors and any Secured
Party, nor any failure to exercise, nor any delay in exercising, on the part of
any Secured Party, any right, power or privilege hereunder or under the
Debentures shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or thereunder preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.

               (b) All of the rights and remedies of each Secured Party with
respect to the Collateral, whether established hereby or by the Debentures or by
any other agreements, instruments or documents or by law shall be cumulative and
may be exercised singly or concurrently.

               (c) This Agreement constitutes the entire agreement of the
parties with respect to the subject matter hereof and is intended to supersede
all prior negotiations, understandings and agreements with respect thereto.
Except as specifically set forth in this Agreement, no provision of this
Agreement may be modified or amended except by a written agreement specifically
referring to this Agreement and signed by the parties hereto.

                                       18
<PAGE>

               (d) In the event any provision of this Agreement is held to be
invalid, prohibited or unenforceable in any jurisdiction for any reason, unless
such provision is narrowed by judicial construction, this Agreement shall, as to
such jurisdiction, be construed as if such invalid, prohibited or unenforceable
provision had been more narrowly drawn so as not to be invalid, prohibited or
unenforceable. If, notwithstanding the foregoing, any provision of this
Agreement is held to be invalid, prohibited or unenforceable in any
jurisdiction, such provision, as to such jurisdiction, shall be ineffective to
the extent of such invalidity, prohibition or unenforceability without
invalidating the remaining portion of such provision or the other provisions of
this Agreement and without affecting the validity or enforceability of such
provision or the other provisions of this Agreement in any other jurisdiction.

               (e) No waiver of any breach or default or any right under this
Agreement shall be considered valid unless in writing and signed by the party
giving such waiver, and no such waiver shall be deemed a waiver of any
subsequent breach or default or right, whether of the same or similar nature or
otherwise.

               (f) This Agreement shall be binding upon and inure to the benefit
of each party hereto and its successors and assigns.

               (g) Each party shall take such further action and execute and
deliver such further documents as may be necessary or appropriate in order to
carry out the provisions and purposes of this Agreement.

               (h) This Agreement shall be construed and enforced in accordance
with, and all questions concerning the construction, validity, interpretation
and performance of this Agreement and all disputes arising hereunder shall be
governed by, the laws of the State of New York, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of New
York or any other jurisdictions) that would cause the application of the laws of
any jurisdictions other than the State of New York. The parties hereto (a) agree
that any legal action or proceeding with respect to this Agreement or any other
agreement, document, or other instrument executed in connection herewith or
therewith, shall be brought in any state or federal court located within the
City of New York in the State of New York, (b) irrevocably waive any objections
which either may now or hereafter have to the venue of any suit, action or
proceeding arising out of or relating to the Security Documents, or any other
agreement, document, or other instrument executed in connection herewith or
therewith, brought in the aforementioned courts, and (c) further irrevocably
waive any claim that any such suit, action, or proceeding brought in any such
court has been brought in an inconvenient forum.

               (i) OBLIGORS AND SECURED PARTIES IRREVOCABLY WAIVE THE RIGHT TO A
TRIAL BY JURY IN ANY ACTION OR PROCEEDING BROUGHT TO ENFORCE ANY PROVISION OF
THIS AGREEMENT, THE DEBENTURE, OR ANY TRANSACTION DOCUMENT.

                                       19
<PAGE>

               (j) This Agreement may be executed in any number of counterparts,
each of which when so executed shall be deemed to be an original and, all of
which taken together shall constitute one and the same Agreement. In the event
that any signature is delivered by facsimile transmission, such signature shall
create a valid binding obligation of the party executing (or on whose behalf
such signature is executed) the same with the same force and effect as if such
facsimile signature were the original thereof.

          (18) JOINDER. In the event a party becomes an Obligor (the "New
Obligor") pursuant to the Joinder Agreement, upon such execution the New Obligor
shall be bound by all the terms and conditions hereof to the same extent as
though such New Obligor had originally executed this Agreement. The addition of
the New Obligor shall not in any manner affect the obligations of the other
Obligors hereunder. Each Company hereto acknowledges that the schedules and
exhibits hereto may be amended or modified in connection with the addition of
any New Obligor to reflect information relating to such New Company.

          (19) PLEDGED EQUITY HELD IN SAFETY DEPOSIT BOX. The Secured Parties
shall hold any Collateral constituting certificated Pledged Equity delivered to
such Secured Parties in a safety deposit box in an institution of the Secured
Parties' choosing until such time the Secured Parties exercise remedies pursuant
to the terms hereof in respect of such Collateral or return such Collateral upon
satisfaction of the Secured Obligations.

          (20) SUBORDINATION. The relative rights of the Parties hereto are
governed by the Letter Agreement.

                            [signature page follows]
