in cash of the First Priority Secured Obligations, the Company shall not permit
there to be any original policy in respect of the QuickBird 2 Insurance other
than any such original which is delivered to the Collateral Agent.

               (g) Continuous Perfection. The Company will not change its name,
                   ---------------------
identity or corporate structure in any manner which might make any financing or
continuation statement filed in connection herewith misleading within the
meaning of Section 9-402(7) of the UCC (or any other then applicable provision
of the UCC) unless the Company shall have given the Collateral Agent at least 60
days' prior written notice thereof and shall have taken all action (or made
arrangements to take such action substantially simultaneously with such change
if it is impossible to take such action in advance) necessary or reasonably
requested by the Collateral Agent to amend such financing statement or
continuation statement so that it is not misleading. The Company will not change
its place of incorporation, place of business or its chief executive office (if
it has more than one place of business) or remove its records from any location,
unless it gives the Collateral Agent at least 60 days' prior written notice
thereof and has taken such action as is necessary to cause the security interest
of the Collateral Agent in the Collateral to continue to be perfected.

               Section 6. The Collateral Agent's Appointment as Attorney-in-
                          --------------------------------------------------
Fact. (a) The Company hereby irrevocably constitutes and appoints the Collateral
----
Agent and any officer or agent thereof, 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 the Company and in the name of the Company or in its own
name, from time to time in the Collateral Agent's discretion, for the purpose of
carrying out the terms of this Agreement, to take any and all appropriate action
and to execute and deliver any and all documents and instruments which the
Collateral Agent may deem necessary or desirable to accomplish the purposes of
this Agreement and, without limiting the generality of the foregoing, hereby
gives the Collateral Agent the power and right, but not the duty, on behalf of
the Company, without notice to or assent by the Company to do the following:

               (i)    to ask, demand, collect, receive and give acquittances and
         receipts for any and all moneys due and to become due under any
         Collateral and, in the name of the Company or in its own name or
         otherwise, to take possession of and endorse and collect any checks,
         drafts, notes, acceptances or other instruments for the payment of
         moneys due under any Collateral and to file any claim or to take any
         other action or proceeding in any court of law or equity or otherwise
         deemed appropriate by the Collateral Agent for the purpose of
         collecting any and all such moneys due under any Collateral whenever
         payable and to file any claim or to take any other action or proceeding
         in any court of law or equity or otherwise deemed appropriate by the
         Collateral Agent for the purpose of collecting any and all such moneys
         due under any Collateral whenever payable;

               (ii)   to pay or discharge taxes, Liens, security interests or
         other encumbrances levied or placed on or threatened against the
         Collateral and to pay any required insurance premiums and related costs
         and expenses; and

               (iii)  (A) to direct any party liable for any payment under any
         of the Collateral to make payment of any and all moneys due, and to
         become due thereunder, directly to the Collateral Agent or as the
         Collateral Agent shall direct; (B) to receive payment of and

                                       9
<PAGE>

          receipt for any and all moneys, claims and other amounts due, and to
          become due at any time, in respect of or arising out of any
          Collateral; (C) to sign and indorse any invoices, freight or express
          bills, bills of lading, storage or warehouse receipts, drafts against
          debtors, assignments, verifications and notices in connection with
          accounts, general intangibles, instruments and other items
          constituting or relating to the Collateral; (D) to commence and
          prosecute any suits, actions or proceedings at law or in equity in any
          court of competent jurisdiction to collect the Collateral or any part
          thereof and to enforce any other right in respect of any Collateral;
          (E) to defend any suit, action or proceeding brought against the
          Company with respect to any Collateral; (F) to settle, compromise or
          adjust any suit, action or proceeding described above and, in
          connection therewith, to give such discharges or releases as the
          Collateral Agent may deem appropriate; and (G) generally to sell,
          transfer, pledge, make any agreement with respect to or otherwise deal
          with any of the Collateral as fully and completely as though the
          Collateral Agent were the absolute owner thereof for all purposes, and
          to do, at the Collateral Agent's option and the Company's expense, at
          any time, or from time to time, all acts and things which the
          Collateral Agent reasonably deems necessary to protect, preserve or
          realize upon the Collateral and the Collateral Agent's Lien therein,
          in order to effect the intent of this Agreement, all as fully and
          effectively as the Company might do.

               (b) The Collateral Agent agrees that, except upon the occurrence
and during the continuance of any Event of Default or default hereunder, it will
forbear from exercising the power of attorney or any rights granted to the
Collateral Agent pursuant to this Section 6; provided that the Collateral Agent
                                             --------
shall, at the direction of the Series A Preferred Stockholders' Representative
or the Series B Preferred Stockholders' Representative, exercise any such power
of attorney or other rights notwithstanding the absence of an Event of Default
or default hereunder if such exercise is necessary or desirable for the grant
to, or maintenance in favor of, the Collateral Agent of the first priority
security interest in the Collateral intended by this Agreement. The Company
hereby ratifies, to the extent permitted by law, all that any said attorney
shall lawfully do or cause to be done by virtue hereof. The power of attorney
granted pursuant to this Section 6, being coupled with an interest, shall be
irrevocable until the Secured Obligations are indefeasibly paid in full in cash.

               (c) The powers conferred on the Collateral Agent hereunder are
solely to protect the Collateral Agent's interests in the Collateral and shall
not impose any duty or obligation upon it to exercise any such powers. The
Collateral Agent shall be accountable only for amounts that it actually receives
as a result of the exercise of such powers and neither it nor any of its
officers, directors, employees or agents shall be responsible to the Company for
any act or failure to act, except for its own gross negligence or willful
misconduct as finally determined by a court of competent jurisdiction. The
Collateral Agent shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured it.

               (d) The Company also authorizes the Collateral Agent, at any time
after the earlier of termination of the First Priority Pledge Agreement and
indefeasible payment in full in cash of the First Priority Secured Obligations
and from time to time thereafter, including, but not

                                       10
<PAGE>

limited to, upon the occurrence and during the continuance of an Event of
Default, (i) to communicate in its own name with any party to any contract
constituting Collateral with regard to the assignment of the right, title and
interest of the Company in and under the Contracts constituting Collateral
hereunder and other matters relating thereto and (ii) to execute, in connection
with the sale or other realization provided for in Section 8 hereof, any
endorsements, assignments or other instruments of conveyance or transfer with
respect to the Collateral. Nothing in this agreement shall be construed to limit
the power of the Collateral Agent at any time after the earlier of termination
of the First Priority Pledge Agreement and indefeasible payment in full in cash
of the First Priority Secured Obligations and from time to time thereafter to
communicate with any insurance company or any agent in respect of the QuickBird
2 Insurance or otherwise exercise any rights or powers granted to it under the
QuickBird 2 Insurance.

               Section 7. Performance by the Collateral Agent of the Company's
                          ----------------------------------------------------
Obligations. If the Company fails to perform or comply with any of its
-----------
agreements contained herein, and the Collateral Agent shall itself perform or
comply, or otherwise cause performance or compliance, with such agreement, the
expenses of the Collateral Agent incurred in connection with such performance or
compliance, together with interest thereon at the highest rate then in effect in
respect of the Secured Obligations, shall be payable by the Company to the
Collateral Agent on demand and shall constitute Secured Obligations secured
hereby.

               Section 8. Remedies; Rights Upon an Event of Default; Allocation
                          -----------------------------------------------------
and Payment of Proceeds Distributions; Special Provisions Regarding Return of
-----------------------------------------------------------------------------
Premiums Under QuickBird 2 Insurance. (a) Subject to Section 2(c)(ii), if an
------------------------------------
Event of Default shall occur and be continuing, the Collateral Agent may
exercise, in addition to all other rights and remedies granted to it 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 UCC and other applicable law. Without limiting the generality of the
foregoing, the Company expressly agrees that in any such event the Collateral
Agent, without demand of performance or other demand, advertisement or notice of
any kind (except the notice specified below of time and place of public or
private sale) to or upon the Company or any other Person (all and each of which
demands, advertisements and/or notices are hereby expressly waived to the
maximum extent permitted by the UCC and other applicable law), may forthwith
collect, receive, appropriate and realize upon the Collateral, or any part
thereof, and/or may forthwith sell, lease, assign, give an option or options to
purchase, or sell or otherwise dispose of and deliver said Collateral (or
contract to do so), or any part thereof, in one or more parcels at public or
private sale or sales, at any exchange or broker's board or any of the
Collateral Agent's offices or elsewhere at such prices as it may deem best, for
cash or on credit or for future delivery without assumption of any credit risk.
The Collateral Agent shall have the right upon any such public sale or sales,
and, to the extent permitted by law, upon any such private sale or sales, to
purchase the whole or any part of said Collateral so sold, free of any right or
equity of redemption, which equity of redemption the Company hereby releases
(subject as aforesaid). The Company further agrees on and after the earlier of
termination of the First Priority Pledge Agreement and indefeasible payment in
full in cash of the First Priority Secured Obligations, at the Collateral
Agent's request, to assemble the Collateral and make it available to the
Collateral Agent at places which the Collateral Agent shall reasonably select,
whether at the Company's premises or elsewhere. The Collateral Agent shall apply
or hold the net proceeds of any such collection, recovery

                                       11
<PAGE>

receipt, appropriation, realization or sale, as provided in Section 8(d) hereof,
the Company remaining liable for any deficiency remaining unpaid after such
application, and only after so paying over such net proceeds to the holders of
Secured Obligations to the extent provided in Section 8(d) and after the payment
by the Collateral Agent of any other amount required by any provision of law,
including Section 9-504(1)(c) of the UCC, need the Collateral Agent account for
the surplus, if any, to the Company. To the maximum extent permitted by
applicable law, the Company waives all claims, damages, and demands against the
Collateral Agent arising out of any repossession, retention or sale of the
Collateral. The Company agrees that the Collateral Agent need not give more than
ten days' notice (which notification shall be deemed given when delivered on an
overnight basis, postage prepaid, addressed to the Company at its address
referred to in Section 12) of the time and place of any public sale or of the
time after which a private sale may take place and that such notice is
reasonable notification of such matters. The Company shall remain liable for any
deficiency if the proceeds of any sale or disposition of the Collateral are
insufficient to pay all amounts to which the Collateral Agent is entitled, the
Company also being liable for the fees and disbursements of any attorneys
employed by the Collateral Agent to collect such deficiency.

               (b) The Company also agrees to pay all costs of the Collateral
Agent, including, without limitation, fees and disbursements of Collateral
Agent's attorneys, incurred in connection with the enforcement of any of its
rights and remedies under this Agreement.

               (c) The Company hereby waives presentment, demand, protest or any
notice (to the maximum extent permitted by applicable law) of any kind in
connection with this Agreement or any Collateral.

               (d) Subject to Section 2(c)(i) and clause (f) below, any cash
held or received by the Collateral Agent as Collateral and all cash proceeds
received by the Collateral Agent in respect of any sale of, collection from, or
other realization upon all or any part of the Collateral (including, without
limitation, any payment in respect of the QuickBird 2 Insurance) (collectively,
"Proceeds Distributions"), shall be applied, distributed or held by the
 ----------------------
Collateral Agent, whether or not there then exists any Default or Event of
Default, as follows:

               First, Proceeds Distributions shall be applied to the payment of
               -----
         and reserve for Collateral Agent Expenses;

               Second, Proceeds Distributions shall be reserved for the benefit
               ------
         of the appropriate Secured Party to be applied equally and ratably to
         the Series A Preferred Stock Obligations and the Series B Preferred
         Stock Obligations;

               Finally, after reserving an amount sufficient for the payment and
               -------
         reserve in full in cash of all of the Secured Obligations as set forth
         above in paragraph "First" and "Second" of clause (d) of this Section
         8, any remaining Proceeds Distributions ("Excess Proceeds
         Distributions") shall be distributed by the Collateral Agent to the
         Company, or its successors or assigns, or to whomsoever may be lawfully
         entitled to receive the same as a court of competent jurisdiction may
         direct.

                                       12
<PAGE>

               (e) It is the intent, as a matter of timing and accommodation
only, that any Excess Proceeds Distributions shall be distributed to the Company
or otherwise in accordance with paragraph "Finally" of clause (d) of Section 8
above substantially concurrently with the setting aside or reserve of Proceeds
Distribution sufficient for the payment of the Secured Obligations as provided
in paragraphs "First" and "Second" of such clause (d); provided that nothing
                                                       -------- ----
shall diminish the prior and senior interest of the Secured Creditors in the
Collateral and the Proceeds Distributions to the extent of the Secured
Obligations as contemplated herein. In the event that the Secured Obligations
are not or have not been paid in full as contemplated by clause (d) of Section 8
above, notwithstanding the distribution of Proceeds Distributions to the
Company, the Company agrees to promptly return or cause the return of such
Proceeds Distributions to the Collateral Agent to the extent necessary to so
fully provide for the Secured Obligations as contemplated herein.

               (f) Subject to Section 2(c)(i) and the following sentence, in the
event that the Collateral Agent receives any Proceeds Distributions that
constitute the return of insurance premiums ("Returned Insurance Premiums")
under the QuickBird 2 Insurance in accordance with the terms thereof, the
Collateral Agent shall hold all Returned Insurance Premiums for a period of 180
days following receipt before distributing such amounts in accordance with
clause (d) of this Section 8. In the event that the Company delivers an
Officers' Certificate to the Collateral Agent prior to the expiration of such
180 day period which (i) states that such Returned Insurance Premiums shall be
used directly for the payment of premiums for QuickBird 2 Insurance complying in
all respects with the provisions of Section 4.10(b) of the 13% Notes Indenture
and (ii) provides instructions for the payment of such premiums directly to the
insurer(s) or their agents, the Collateral Agent shall promptly pay such
Returned Insurance Premiums in accordance with such payment instructions.

               Section 9. Limitation on the Collateral Agent's Duty in Respect
                          ----------------------------------------------------
of Collateral. The Collateral Agent shall not have any duty as to any Collateral
-------------
in its possession or control or in the possession or control of any agent or
nominee of it or any income thereon or as to the preservation of rights against
prior parties or any other rights pertaining thereto, except that the Collateral
Agent shall use reasonable care with respect to the Collateral in its possession
or under its control. In accordance with Section 9-207 of the UCC, the
Collateral Agent shall be deemed to have used reasonable care if it observes
substantially the same standard of care with respect to the custody or
preservation of the Collateral as it observes with respect to similar assets
owned by the Collateral Agent. Without limiting the generality of the foregoing,
the Collateral Agent shall not be under any obligation to take any steps to
preserve rights in the Collateral against any other parties, to sell the same if
it threatens to decline in value, or to exercise any rights represented thereby
(including rights with respect to calls, conversions, exchanges, maturities, or
tenders); provided, however, that the Collateral Agent may, at its option, do
          --------  -------
so, and any and all reasonable expenses incurred in connection therewith shall
be for the account of the Company. Upon written request of the Company, the
Collateral Agent shall account for any moneys received by it in respect of any
foreclosure on or disposition of the Collateral owned by the Company.

               Section 10. Security Interest Absolute. All rights of the
                           --------------------------
Collateral Agent and security interests hereunder, and all obligations of the
Company hereunder, shall be absolute and unconditional irrespective of:

                                       13
<PAGE>

               (i)   any lack of validity or enforceability of any provision of
         this Agreement, or any other agreement, certificate or instrument
         relating to the Series A Preferred Stock Obligations or the Series B
         Preferred Stock Obligations;

               (ii)  any change in the time, manner or place of payment of, or
         in any other term of, or any increase in the amount of, all or any of
         the Secured Obligations, or any other amendment, waiver or modification
         of any term of, or any consent to any departure from any requirement
         of, this Agreement or any other agreement, certificate or instrument
         relating to the Series A Preferred Stock Obligations or the Series B
         Preferred Stock Obligations;

               (iii) any exchange, release or non-perfection of any security
         interest or lien on any other collateral, or any release or amendment
         or waiver of any term of any guaranty of, or security for, or consent
         to departure from any requirement of any guaranty or other credit
         support of or for, all or any of the Secured Obligations; or

               (iv)  all suretyship defenses and any other circumstance which
         might otherwise constitute a defense available to, or a discharge of, a
         borrower, a pledgor or a surety.

               (a) No failure on the part of the Collateral Agent or any Secured
Party to exercise, and no delay in exercising any right hereunder shall operate

hereunder preclude any other or further exercise thereof or

                                       15
<PAGE>

the exercise of any other right. The remedies herein provided are cumulative,

of this Agreement but the failure to deliver a manually executed counterpart
shall not affect the validity, enforceability, and binding effect of this
Agreement.

representatives, successors and assigns of the Company, and shall, together with
the rights and remedies of the Collateral Agent hereunder, inure to the benefit
of the Collateral Agent for the benefit of the Secured Parties, and their
