                SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN AGREEMENT

         This agreement (the "Agreement") is made and effective as of ________,
2000 between CSK AUTO, INC., an Arizona corporation (the "Company") and MAYNARD
JENKINS, an individual residing at 6052 E. Jenan Drive, Scottsdale, AZ 85254
(the "Executive").

         WHEREAS, the parties have entered into an Employment Agreement, amended
and restated as of June 12, 1998, whereby the Company has secured the exclusive
services of the Executive (the "Employment Agreement"); and

         WHEREAS, in addition to the benefits payable pursuant to the Employment
Agreement, the parties wish to have the Company provide supplemental executive
retirement plan benefits ("SERP benefits") to the Executive on an unfunded basis
pursuant to the provisions of this Agreement;

         NOW, THEREFORE, in consideration of the foregoing and of the respective
covenants and agreements of the parties herein contained, the parties hereto
agree as follows:

         1. Definitions. Unless otherwise defined herein, terms defined in the
Employment Agreement shall be used as so defined.

         2. Supplemental Executive Retirement Benefits.

                  (a) Time of Payment. Subject to satisfaction of the vesting
requirements set forth in Section 2(c) hereof and except as otherwise provided
in this Section 2, the Executive shall be entitled to receive SERP benefits for
a ten year period, the first such payment to be made on the earlier to occur of
(i) February 1, 2006, and (ii) the first anniversary of the effective date of
the termination of the Executive's employment for any reason other than for
Cause, and additional payments to be made on each succeeding anniversary of such
first payment through and including the ninth such anniversary (each such date
being hereinafter called a "Benefit Payment Date").

                  (b) Amount of Benefit. The gross amount payable to the
Executive on each Benefit Payment Date shall be $600,000 less applicable income
and payroll taxes (the "Maximum SERP Benefit"), or, if less than 100% vesting is
attained, such lesser amount as shall correspond to the degree of vesting
attained.

                  (c) Vesting. The Executive shall vest in 33 1/3% of the
Maximum SERP Benefit on February 1, 2002, provided he is a full time executive
of the Company on such date, and shall vest in an additional 16 2/3% of the
Maximum SERP Benefit on each of the next four anniversaries of such date
provided the Executive is a full time executive of the Company on any such date.
Thus, for example, if the Executive is employed by the Company as of February 1,
2004, he will have vested by such date in 66 2/3% of the Maximum SERP Benefit
(66 2/3% x $600,000 = $400,000 per year for ten years commencing in 2006).
<PAGE>   2
                  (d) Termination of Employment. In the event the Executive's
employment with the Company shall terminate prior to February 1, 2006, vesting
and payment of SERP benefits hereunder shall be determined in accordance with
the following provisions:

                           (i) Death or Disability. In the event the Executive's
employment with the Company is terminated prior to February 1, 2006 because of
his death or because of his permanent disability (as determined under the
Company's long-term disability program), then the Executive shall be vested in
his SERP benefits through the date of such termination, vesting for the year of
termination being prorated, on a monthly basis, through the end of the last
complete calendar month preceding such termination. Thus, for example, if such
termination shall occur on July 31, 2004, the Executive shall be deemed to have
satisfied 75% of the vesting requirement and shall be vested in 75% of the
Maximum SERP Benefit. In the event of such a termination because of death or
permanent disability, the Executive or his Beneficiary shall receive his vested
SERP benefit over a ten year period commencing on the earlier to occur of (i)
February 1, 2006, and (ii) the first anniversary of the effective date of the
termination of the Executive's employment for any reason other than for Cause,
or, in the sole and absolute discretion of the Board of Directors of the Company
(the "Board"), in lieu of such benefit, a lump sum payment, as soon as
practicable following such termination, of an actuarially equivalent amount,
discounted to present value at an eight percent (8 %) annual interest rate.

                           (ii) Termination Without Good Cause or With Good
Reason. In the event that the Executive's employment is terminated prior to
February 1, 2006 either by the Company without Good Cause or by the Executive
with Good Reason, then, Executive shall thereupon be deemed to be fully vested
in the Maximum SERP Benefit, such benefit to be paid in accordance with Section
2(a). For all purposes of this Section 2, the term "Good Cause" shall have the
meaning ascribed to it in the Employment Agreement but shall not include the
Executive's death or permanent disability, which are provided for in Section
2(d)(i) above and the term "Good Reason" shall have the meaning ascribed to it
in the Employment Agreement.

                           (iii) Termination With Good Cause or Without Good
Reason. In the event that the Executive's employment is terminated prior to
February 1, 2006 either by the Company with Good Cause or by the Executive
without Good Reason, then the Executive shall be vested in his SERP benefits
through the date of such termination, vesting for the year of termination being
prorated, on a monthly basis, through the end of the last complete calendar
month preceding such termination. Payment of such vested SERP benefits shall be
made in accordance with Section 2(a).

         3. Acceleration of Payment. Notwithstanding the foregoing Section 2,
the Board, in its sole discretion, may accelerate the payment of all or part of
the Executive's SERP benefits if so requested by the Executive or, after the
Executive's death, by his Beneficiary; provided, however, that any such
accelerated payment may be permitted only in case of an unforeseeable emergency
(within the meaning of Section 457 of the Internal Revenue Code and the
regulations promulgated thereunder) that is caused by an event beyond the
control of the Executive or his Beneficiary and that would result in severe
financial hardship to such person if accelerated payment were not permitted. Any
such accelerated payment shall be limited to the amount necessary to meet or
satisfy the emergency.

                                       2

         4. Designation of Beneficiary. Executive shall file with the Company a
written designation of one or more persons as the Beneficiary who shall be
entitled to receive the amounts, if any, payable hereunder after Executive's
death. Executive may, from time to time, revoke or change his Beneficiary
designation without the consent of any prior Beneficiary by filing a new
designation with the Company. The last such designation received by the Company
shall be controlling; provided, however, that no designation, or change or
revocation thereof, shall be effective unless received by the Company prior to
Executive's death, and in no event shall it be effective as of a date prior to
such receipt. If no such Beneficiary designation is in effect at the time of
Executive's death, or if no designated Beneficiary survives Executive,
Executive's spouse shall be deemed to have been designated his Beneficiary or,
if his spouse does not survive Executive, Executive's estate shall be deemed to
have been designated his Beneficiary and the executor or administrator thereof
shall receive the amount, if any, payable hereunder after Executive's death. If
the Company is in doubt as to the right of any person to receive all or part of
such amount, the Company may retain such amount until the rights thereto are
determined, or the Company may pay such amount into any court of appropriate
jurisdiction and such payment shall be a complete discharge of the liability of
the Company therefor.

         5. Administration of the Agreement and Claims.

                  (a) Administration. This Agreement shall be administered by
the Compensation Committee of the Board if such committee exists, otherwise by
the Board ("the Committee"), which shall have full power, discretion and
authority to interpret, construe and administer this Agreement and any part
thereof.

                  (b) Claims for Benefits. Any claim for SERP benefits by
Executive or anyone claiming through Executive under this Agreement shall be
delivered in writing by the claimant to the Committee. The claim shall identify
the benefits being requested and shall include a statement of the reasons why
the benefits should be granted. The Committee shall grant or deny the claim. If
the claim is denied in whole or in part, the Committee shall give written notice
to the claimant setting forth: (a) the reasons for the denial, (b) specific
reference to pertinent provisions of the Agreement on which the denial is based,
(c) a description of any additional material or information necessary to request
a review of the claim and an explanation of why such material or information is
necessary, and (d) an explanation of the Agreement's claim review procedure. The
notice shall be furnished to the claimant within a period of time not exceeding
90 days after receipt of the claim, except that such period of time may be
extended, if special circumstances should require, for an additional 90 days
commencing at the end of the initial 90-day period. Written notice of any such
extension shall be given to the claimant before the expiration of the initial
90-day period and shall indicate the special circumstances requiring the
extension and the date by which the final decision is expected to be rendered.

                  (c) Appeals Procedure. A claimant who has been denied a claim
for benefits, in whole or in part, may, within a period of 60 days following his
receipt of the denial, request a review of such denial by filing a written
notice of appeal with the Committee. In connection with an appeal, the claimant
(or his authorized representative) may review pertinent documents and may submit
evidence and arguments in writing to the Committee. The Committee may decide the
questions presented by the appeal, either with or without holding a hearing, and
shall issue to the claimant a written notice setting forth: (a) the specific
reasons for the decision and

                                       3
<PAGE>   4
(b) specific reference to the pertinent provisions of the Agreement on which the
decision is based. The notice shall be issued within a period of time not
exceeding 60 days after receipt of the request for review; except that such
period of time may be extended, if special circumstances (including, but not
limited to, the need to hold a hearing) should require, for an additional 60
days commencing at the end of the initial 60-day period. Written notice of any
such extension shall be provided to the claimant prior to the expiration of the
initial 60-day period.

         6. Executive is Unsecured Creditor. Executive shall be a general
unsecured creditor of the Company with respect to his right to receive payments
of SERP benefits hereunder. This Agreement represents a mere promise by the
Company to make payments of deferred compensation (i.e., SERP benefits) in the
future. All payments of deferred compensation to be made hereunder shall be paid
from the general funds of the Company. It is the intention of the Company and
Executive that this Agreement and the Company's obligation to make payments of
deferred compensation hereunder be unfunded both for tax purposes and for
purposes of Title I of ERISA.

         7. No Assignment of Rights. This Agreement shall be binding upon and
inure to the benefit of the Company and its successors and assigns, and
Executive, his Beneficiary and his estate. The rights of Executive, his
Beneficiary and his estate to payments of SERP benefits hereunder are expressly
declared not to be subject in any manner to anticipation, alienation, sale,
transfer, assignment, pledge, encumbrance, attachment, or garnishment by
creditors of Executive, his Beneficiary or his estate. Any attempted disposition
of such rights shall be null and void.

         8. Facility of Payment. If the Committee shall find that any person to
whom any payment is payable under the Agreement is unable to care for his
affairs because of illness or accident, or is a minor, then any payment due
(unless a prior claim therefor shall have been made by a duly appointed
guardian, committee or other legal representative) may, if the Committee so
elects, be paid to his spouse, a child, a parent, or a brother or sister, or any
other person deemed by the Committee to have incurred expenses for such person
otherwise entitled to payment, in such manner and proportions as the Committee
may determine. Any such payment shall be a complete discharge of the liabilities
of the Company under the Agreement as to the amount of the payment.

         9. Withholding of Taxes. The Company shall withhold from any and all
amounts payable hereunder appropriate federal, state and local income and
payroll taxes.

         10. Notices. Unless either party notifies the other to the contrary,
any notice required hereunder shall be duly given if delivered in person or by
certified or registered first class mail (a) if to the Company, to the
President, CSK Auto Corporation, and (b) if to Executive, to the address shown
at the beginning of this Agreement.

         11. Entire Agreement. The terms and provisions of this Agreement
constitute the entire agreement between the parties and supersede any previous
oral or written communications, representations or agreements with respect to
the subject matter hereof.

                                       4

         12. Severability. The invalidity or unenforceability of any particular
provision of this Agreement shall not affect the other provisions hereof, and
this Agreement shall be construed in all respects as if the invalid or
unenforceable provision had been omitted.

         13. Successors. The Company's obligation hereunder shall be binding
legal obligations of any successor to all or substantially all of the Company's
business by purchase, merger, consolidation or otherwise. The Executive may not
assign this Agreement during his life, and upon his death, this Agreement shall
be binding upon and inure to the benefit of his heirs, legatees and the legal
representative of each.

         14. Governing Law; Legal Proceedings. This Agreement shall be governed
by and construed and interpreted pursuant to the laws of the State of Arizona
from time to time in effect.

         15. Amendment. This Agreement may be amended only by a written document
signed by both parties.

         IN WITNESS WHEREOF, the parties have executed this Agreement effective
as of the day and year first above written.

                  THIS ASSET PURCHASE AGREEMENT (this "AGREEMENT") is entered
into as of September 11, 2000, by and among WAVEPHORE NETWORKS, INC., a Delaware
corporation ("WPN"), WAVO CORPORATION, an Indiana corporation and the parent of
WPN ("WAVO"), and CIDERA, INC., a Delaware corporation (the "PURCHASER"). For
the purposes of this Agreement, WPN and WAVO are sometimes referred to

WAVO's and WPN's knowledge, all of the Assets (as defined below) being
transferred hereunder are the assets and operations of WPN (and not of WAVO).

                                    RECITALS

         WHEREAS, the Sellers wish to sell and the Purchaser wishes to purchase
the Assets (as defined below to include all operations) of the Sellers Related

         Seller), and all rights of indemnity, warranty rights, rights of
         contribution, rights to refunds, rights of reimbursement and other
         rights of recovery possessed by the Sellers Related to the Wireless
         Business (regardless of whether such rights are currently exercisable);

                           (8)      all advertising and promotional materials
         Related to the Wireless Business possessed by the Sellers; and

1.2      PURCHASE PRICE.

         (a)      As consideration for the sale of the Assets to the Purchaser:

                  (i)      at the Closing, the Purchaser shall pay to WPN,
         $11,500,000 in cash (the "CLOSING DATE CASH") by wire transfer in
         immediately available funds;

                  (ii)     at the Closing, the Purchaser shall deposit the sum
         of $500,000 (the "ESCROW FUND" and together with the Closing Date Cash,
         the "CASH CONSIDERATION") in an escrow account (the "ESCROW ACCOUNT")
         to be established as of the Closing Date (as defined below) pursuant to
         an Escrow Agreement (as defined below) among WPN, the Purchaser, and
         U.S. Trust Corporation (or another escrow agent

                                       2
<PAGE>   8
         reasonably acceptable to the parties) (the "ESCROW AGENT"), in
         substantially the form of EXHIBIT B (the "ESCROW AGREEMENT"). Subject
         to the terms of the Escrow Agreement, such Escrow Fund shall be held in
         the Escrow Account for 60 days after the Closing Date, after which it
         shall be delivered and paid to WPN, less any amount used for any
         adjustment(s) to Cash Consideration described in Section 1.2(b)(i) and
         (ii). The terms of the use and distribution of the Escrow Fund are
         described more fully in the Escrow Agreement;

                  (iii)    at the Closing, the Purchaser shall issue to WPN
         285,731 shares of common stock of the Purchaser (the "PURCHASER COMMON
         STOCK") subject to adjustment as described in Section 1.2(b); and

                  (iv)     at the Closing, the Purchaser shall assume the
         Assumed Liabilities by delivering to the Sellers an Assumption
         Agreement in substantially the form of EXHIBIT C (the "ASSUMPTION
         AGREEMENT").

All consideration paid by the Purchaser under this Agreement shall be paid to or
in the name of WPN.

         (b)      The consideration described in Section 1.2(a) is subject to
adjustment as follows:

                  (i)      FIRST ADJUSTMENT TO CASH CONSIDERATION. To the extent
that the historical net book value of the Transferred Tangible Assets of the
Wireless Business is less than $4,000,000 (as determined by the Closing Date
Audit as defined in Section 10.1), then the Cash Consideration shall be reduced,
dollar-for-dollar, for every dollar that Transferred Tangible Assets is less
than $4,000,000. Any such reduction shall be paid solely from the Escrow Fund.
Although the Purchaser may only seek such Cash Consideration reduction from the
Escrow Fund if Transferred Tangible Assets of the Wireless Business are less
than $4,000,000, the foregoing sentence shall not limit the Purchaser from
seeking indemnification from the Sellers for the breach of any representation or
warranty in the Transactional Agreements.

                  (ii)     SECOND ADJUSTMENT TO CASH CONSIDERATION. In addition
to any adjustment to the Cash Consideration described in Section 1.2(b)(i), to
the extent that the historical net book value of the Assumed Liabilities of the
Wireless Business (as determined by the Closing Date Audit) are greater than
$490,000, then the Cash Consideration shall be reduced, dollar-for-dollar, for
every dollar that such Assumed Liabilities are greater than $490,000. Any such
reduction may be paid from the Escrow Fund or from the Closing Date Cash at the
option of the Purchaser.

                  (iii)    ADJUSTMENT TO PURCHASER COMMON STOCK. The parties
hereto acknowledge that the Purchaser has been negotiating the sale of its
Series D Preferred Stock. The parties agree that if (1) the Purchaser closes its
sale of Series D Preferred Stock within 90 days of the date of this Agreement,
and (2) such stock is sold for less than $8.7495 per share, then WPN shall be
entitled to an aggregate number of shares of Common Stock of the Purchaser
(including the 285,731 shares described above) equal to $2,500,000 divided by
the price at which the Series D Preferred Stock is actually sold. By way of
illustration, if the Series D Preferred

                                       3
<PAGE>   9
Stock is sold for $8.50, then WPN shall be entitled to an aggregate of 294,118
shares of Purchaser Common Stock (or an additional 8,387 shares due to such
adjustment).

         (c)      For purposes of this Agreement "ASSUMED LIABILITIES" shall
mean only the following liabilities of the Sellers:

                  (i)      all liabilities of the Sellers related to the
         Wireless Business and listed on EXHIBIT G that arose from bona fide
         transactions, entered into with Persons who (at the time of such
         transaction) were not Related Parties to either Seller, in the Ordinary
         Course of Business and that remain unpaid as of the Closing Date. (On
         the date of this Agreement, EXHIBIT G attached hereto will contain
         those types or categories of liabilities to be assumed by the
         Purchaser, and the amounts of such Assumed Liabilities as of the date
         of this Agreement. The amounts described on EXHIBIT G shall be updated
         at the time of the Closing to reflect the actual Assumed Liabilities
         that the Purchaser will be assuming at the Closing); and

                  (ii)     the obligations of the Sellers under the operating
         and capital leases identified on EXHIBIT D to the Agreement, but only
         to the extent such obligations (A) arise after the Closing Date; (B) do
         not arise from or relate to any Breach by a Seller of any provision of
         any of such Contracts, (C) do not arise from or relate to any event,
         circumstance or condition occurring or existing on or prior to the
         Closing Date that, with notice or lapse of time, would constitute or
         result in a Breach of any of such Contracts, and (D) are ascertainable
         (in nature and amount) solely by reference to the express terms of such
         Contracts;

provided, however, that notwithstanding the foregoing, and notwithstanding
anything to the contrary contained in this Agreement, the "ASSUMED LIABILITIES"
shall not include, and the Purchaser shall not be required to assume or to
perform or discharge:

                           (1)      any Liability of any other Person, except of

                  a Seller;

                           (2)      any Liability of a Seller arising out of or
                  relating to the execution, delivery or performance of any of
                  the Transactional Agreements;

                           (3)      any Liability of a Seller for any fees,
                  costs or expenses of the type referred to in Section 10.4 of
                  this Agreement;

                           (4)      any Liability of a Seller arising from or
                  relating to any action taken by a Seller, or any failure on
                  the part of a Seller to take any action, at any time after the
                  Closing Date;

                           (5)      any Liability of a Seller arising from or
                  relating to (x) any services performed by a Seller prior to
                  the Closing for any customer, or (y) any claim or Proceeding
                  against a Seller;

                           (6)      any Liability under any Contract, if the
                  Sellers shall not have obtained, prior to the Closing Date,
                  any Consent required to be obtained from any Person

                                       4
<PAGE>   10
                  with respect to the assignment or delegation to the Purchaser
                  of any rights or obligations under such Contract;

                           (7)      any Liability that arises or exists by
                  virtue of any Breach of (x) any representation or warranty
                  made by a Seller in any of the Transactional Agreements, or
                  (y) any covenant or obligation of a Seller contained in any of
                  the Transactional Agreements; or

                           (8)      any other Liability that is not referred to
                  specifically in clause "(i)" or "(ii)" of this sentence.

         1.3      SALES TAXES. The Purchaser and WPN shall each bear and pay 50%
of any sales taxes, use taxes, transfer taxes, documentary charges, recording
fees or similar taxes, charges, fees or expenses that may become payable in
connection with the sale of the Assets to the Purchaser or in connection with
any of the other Transactions. For the avoidance of doubt, notwithstanding
anything to the contrary in the foregoing sentence, the Purchaser shall not
assume any Tax obligation of the Sellers for Taxes incurred prior to the Closing
Date other than that those set forth on EXHIBIT G.

         1.4      ALLOCATION. The consideration referred to in Sections
1.2(a)(i) and 1.2(a)(ii) is to be allocated as mutually agreed by the Purchaser
and WPN. The Purchaser shall submit to WPN a proposed allocation (the "PROPOSED
ALLOCATION") within 30 days of the date hereof. If WPN does not notify the
Purchaser within 15 days of receipt of the Proposed Allocation of any
disagreement with the Proposed Allocation then the Proposed Allocation shall
become the final allocation (the "ALLOCATION"). If WPN notifies the Purchaser
within such 15 day period (the "ALLOCATION NOTICE") of WPN's disagreement with
the Proposed Allocation, then WPN and the Purchaser shall in good faith attempt
to resolve their disagreement. If such disagreement is not resolved within 30
days from the delivery of the Allocation Notice then such disagreement shall be
resolved by an independent accounting firm jointly selected by the accountant
for the Purchaser and the accountants for the Sellers. In the event the
allocation is determined after delivery of the Allocation Notice either by
discussions between WPN and the Purchaser or by the accounting firm selected in
the manner herein provided then such allocation shall be the Allocation. The
parties agree that except as otherwise required by law (i) the Allocation shall
be binding on the Purchaser and the Sellers for all federal, state and local tax
purposes and (ii) the Purchaser and the Sellers shall file with their respective
federal income tax returns consistent IRS Forms 8594-Asset Acquisition
Statements Under Section 1060, including any required amendments thereto which
shall reflect the allocations set forth in the Allocation. The parties
acknowledge that such Allocation will be reasonable. The Purchaser and WPN shall
each bear and pay 50% of the costs of any accounting firm retained to resolve
any disputes pursuant to this Section 1.4.

         1.5      CLOSING.

                  (a)      The closing of the sale of the Assets to the
Purchaser (the "CLOSING") shall take place at the offices of Cooley Godward LLP
in Reston, Virginia, at 10:00 a.m. on the date that all of the closing
conditions set forth herein are either satisfied or waived, or such other time
and place as the Purchaser and WPN agree to in writing. Such Closing may be
conducted by the

                                       5
<PAGE>   11
exchange of facsimile signature pages. For purposes of this Agreement, "CLOSING
DATE" shall mean the time and date as of which the Closing actually takes place.

                  (b)      At the Closing:

                           (i)      the Sellers shall execute and deliver to the
         Purchaser such bills of sale, endorsements, assignments and other
         documents as may (in the reasonable judgment of the Purchaser or its
         counsel) be necessary or appropriate to assign, convey, transfer and
         deliver to the Purchaser good and valid title to the Assets free of any
         Encumbrances; provided, however, the foregoing requirement that such
         Assets be free of any Encumbrances shall not limit the Purchaser's
         obligations to assume the Assumed Liabilities;

                           (ii)     the Purchaser shall pay to the Sellers the
         Closing Date Cash and issue a stock certificate in the name of WPN for
         the Purchaser Common Stock contemplated by Section 1.2(a)(i) and (iii);

                           (iii)    the parties hereto shall execute and deliver
         the Escrow Agreement in the form attached hereto (subject to changes
         required by the Escrow Agent), and the Purchaser shall deposit the sum
         contemplated by Section 1.2(a)(ii) in the Escrow Account;

                           (iv)     the Purchaser shall execute and deliver to
         the Sellers the Assumption Agreement;

                           (v)      the Purchaser and the Sellers shall execute,
         and deliver to each other, the Services Agreement (described in Section
         6.10);

                           (vi)     the Sellers and the Purchaser shall execute,
         and deliver to each other, a Noncompetition Agreement in the form of
         EXHIBIT E; and

                           (vii)    each party hereto shall execute and deliver
         to the other a certificate (each, a "CLOSING CERTIFICATE") setting

notwithstanding anything to the contrary contained in this Section 9.1(c), such

force and effect until such time as each and every claim (including any
indemnification claim asserted by any Indemnitee under Section 9.2) that is

Notwithstanding anything to the contrary in this Agreement, the Sellers'
indemnity obligations hereunder shall not exceed the value of the consideration

indemnity obligations hereunder shall not exceed the value of the consideration
received by the Purchaser under the Agreement.

         9.4      NONEXCLUSIVITY OF INDEMNIFICATION REMEDIES. The
indemnification remedies and other remedies provided in this Section 9 shall not
be deemed to be exclusive. Accordingly, the exercise by any Person of any of its
rights under this Section 9 shall not be deemed to be an election of remedies

of, any other right or remedy that such Person may be entitled to exercise
(whether under this Agreement, under any other Contract, under any statute, rule
or other Legal Requirement, at common law, in equity or otherwise).

         9.5      DEFENSE OF THIRD PARTY CLAIMS. In the event of the assertion
or commencement by any Person of any claim or Proceeding with respect to which
any Person (the "indemnifying party") may become obligated to indemnify, hold
harmless, compensate or reimburse any Person entitled to indemnification,
compensation or reimbursement hereunder (the "indemnified party") pursuant to
this Section 9, the indemnified party shall (a) notify the indemnifying party
thereof as promptly as practicable after becoming aware of the claim or
Proceeding (it being understood that no delay on the part of the indemnified
party in so notifying the indemnifying party shall relieve the indemnifying
party from any obligation hereunder unless, and then solely to the extent that,
the indemnifying party is prejudiced thereby), and (b) have the right, at its
election, to designate the indemnifying party to assume the defense of such
claim or Proceeding at the sole expense of the indemnifying party. If the
indemnified party so elects to designate the indemnifying party to assume the
defense of any such claim or Proceeding:

                  (a)      the indemnifying party shall proceed to defend such
         claim or Proceeding in a diligent manner with counsel reasonably
         satisfactory to the indemnified party;

                  (b)      the indemnified party shall make available to the
         indemnifying party any documents and materials in the possession of the
         indemnified party that may be necessary to the defense of such claim or
         Proceeding;

                  (c)      the indemnifying party shall keep the indemnified
         party informed of all material developments and events relating to such
         claim or Proceeding;

                  (d)      the indemnified party shall have the right to
         participate in (but not control) the defense of such claim or
         Proceeding at its own expense using counsel of its choice;

                  (e)      the indemnifying party shall not settle, adjust or
         compromise such claim or Proceeding without the prior written consent
         of the indemnified party (which consent shall not be unreasonably
         withheld); and

                  (f)      the indemnified party may (if the indemnifying party
         breaches in any material respect any of the provisions of this Section
         9.5) assume the defense of such claim or Proceeding.

If the indemnified party does not elect to designate the indemnifying party to
assume the defense of any such claim or Proceeding (or if, after initially
designating the indemnifying party to assume such defense, the indemnified party
elects to assume such defense in accordance with paragraph "(f)" above), the
indemnified party may proceed with the defense of such claim or Proceeding on
its own. If the indemnified party so proceeds with the defense of any such claim
or Proceeding on its own:

                           (i)      all reasonable expenses relating to the
         defense of such claim or Proceeding (to the extent indemnifiable,
         reimbursable or payable under this Section 4) shall be borne and paid
         exclusively by the indemnifying party;

                           (ii)     the indemnifying party shall make available
         to the indemnified party any documents and materials in the possession
         or control of the indemnifying party that may be necessary to the
         defense of such claim or Proceeding;

                           (iii)    the indemnified party shall keep the
         indemnifying party informed of all material developments and events
         relating to such claim or Proceeding;

                           (iv)     the indemnifying party shall have the right
         to participate in (but not control) the defense of such claim or
         Proceeding at its own expense using counsel of its choice; and

                           (v)      the indemnified party shall have the right
         to settle, adjust or compromise such claim or Proceeding with the
         consent of the indemnifying party; provided, however, that the
         indemnifying party shall not unreasonably withhold such consent.

10.      CERTAIN POST-CLOSING COVENANTS; MISCELLANEOUS.

         10.1     FURTHER ACTIONS; RIGHT OF FIRST REFUSAL.

                  (a)      CLOSING DATE AUDIT. From and after the Closing Date,
the Sellers and their Representatives shall permit, and use their Best Efforts
to assist Deloitte & Touche LLP (or another accounting firm selected by the
Purchaser) to prepare audited financial statements for the Wireless Business as
of and for the periods ended December 31, 1997, December 31, 1998, December 31,
1999, and an audited balance sheet for the Wireless Business as of the Closing
Date. The fees and expenses of the auditors for the foregoing shall be paid by
the Purchaser. Such audit of the balance sheet as of the Closing Date shall
hereinafter be referred to as the "CLOSING DATE AUDIT".

                  (b)      ASSIGNMENT OF PATENTS. The Sellers agree that if any
patents owned by a Seller or any of its subsidiaries are necessary for the
operation of the Wireless Business and are more closely related to the business
of the Wireless Business than of any of the Sellers' businesses, the Sellers
shall execute (or cause to be executed) and deliver such documents and take such
other actions as the Purchaser may reasonably request, for the purpose of
transferring any such patents to the Purchaser, and the Purchaser shall then
grant a license to the Sellers to use and exploit the related technology to the
full extent needed for the Sellers to operate their

                                       32
<PAGE>   38
business related to such technology. The Sellers agree that if any patents owned
by a Seller or any of its subsidiaries are necessary for the operation of the
Wireless Business and are more closely related to the business of a Seller than
the business of the Wireless Business, the Sellers shall execute (or cause to be
executed) and deliver such documents and take such other actions as the
Purchaser may reasonably request, for the purpose of granting a license to use
and exploit the related technology to the Purchaser to the full extent needed
for the Purchaser to operate its business.

                  (c)      GENERAL COOPERATION. From and after the Closing Date,
the Sellers shall cooperate with the Purchaser and the Purchaser's affiliates
and Representatives, and shall execute and deliver such documents and take such
other actions as the Purchaser may reasonably request, for the purpose of
evidencing the Transactions and putting the Purchaser in possession and control
of all of the Assets. Without limiting the generality of the foregoing, from and
after the Closing Date, the Sellers shall (i) assist the Purchaser in obtaining
any consent not obtained prior to the Closing Date (following any waiver by the
Purchaser of a closing condition requiring the Sellers to obtain such consent)
and (ii) promptly remit to the Purchaser any funds that are received by a Seller
and that are included in, or that represent payment of receivables included in,
the Assets. Each Seller: (A) hereby irrevocably authorizes the Purchaser, at all
times on and after the Closing Date, to endorse in the name of such Seller any
check or other instrument that is made payable to such Seller and that
represents funds included in, or that represents the payment of any receivable
included in, the Assets; and (B) hereby irrevocably nominates, constitutes and
appoints the Purchaser as the true and lawful attorney-in-fact of such Seller
(with full power of substitution) effective as of the Closing Date, and hereby
authorizes the Purchaser, in the name of and on behalf of such Seller, to
execute, deliver, acknowledge, certify, file and record any document, to
institute and prosecute any Proceeding and to take any other action (on or at
any time after the Closing Date) that the Purchaser may deem appropriate for the
purpose of (1) collecting, asserting, enforcing or perfecting any claim, right
or interest of any kind that is included in or relates to any of the Assets, (2)
defending or compromising any claim or Proceeding relating to any of the Assets,
or (3) otherwise carrying out or facilitating any of the Transactions. The power
of attorney referred to in the preceding sentence is and shall be coupled with
an interest and shall be irrevocable, and shall survive the dissolution or
insolvency of a Seller.

                  (d)      PURCHASER RIGHT OF FIRST REFUSAL.

                           (i)      If WPN proposes to Transfer any shares of
Purchaser Common Stock, then WPN shall promptly give written notice (the
"NOTICE") to the Purchaser at least 30 days prior to the closing of such
Transfer. The Notice shall describe in reasonable detail the proposed Transfer
including, without limitation, the number of shares of Purchaser Common Stock to
be transferred, the nature of such Transfer, the consideration to be paid, and
the name and address of each prospective purchaser or transferee.

                           (ii)     The Purchaser shall then have the right,
exercisable upon written notice to WPN (the "PURCHASER NOTICE") within 15 days
after the receipt of the Notice, to purchase all or any portion of the Purchaser
Common Stock subject to the Notice on the same terms and conditions as set forth
therein. If the Purchaser exercises such rights, it shall effect the

                                       33
<PAGE>   39
purchase of the Purchaser Common Stock, including payment of the purchase price,
not more than 10 days after delivery of the Purchaser Notice, and at such time
WPN shall deliver to the Purchaser the certificate(s) representing the Purchaser
Common Stock to be purchased by the Purchaser, each certificate to be properly
endorsed for transfer.

                           (iii)    If the Purchaser does not purchase all of
the Purchaser Common Stock covered by the Notice, then WPN may, not later than
60 days following delivery to the Purchaser of the Notice, enter into an
agreement providing for the closing of the Transfer of the Purchaser Common
Stock not purchased by the Purchaser to such prospective purchaser or transferee
on terms and conditions not more favorable to the transferor than those
described in the Notice. Any proposed Transfer on terms and conditions more
favorable than those described in the Notice, as well as any subsequent proposed
Transfer of any of the Purchaser Common Stock by WPN, shall again be subject to
the first refusal of the Purchaser and shall require compliance by WPN with the
procedures described in this Section 10(c).

                           (iv)     In the event that WPN should Transfer any of
the Purchaser Common Stock in contravention of the rights described in this
Section 10(c), such transfer shall be considered void.

                           (v)      Each certificate representing shares of
Purchaser Common Stock shall be endorsed with the following legend: "THE SALE,
PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS
CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN RIGHT OF FIRST
REFUSAL BY AND BETWEEN WPN CORPORATION AND CIDERA, INC." The parties agree that
the Purchaser may instruct its transfer agent to impose transfer restrictions on
the shares represented by certificates bearing the legend referred to in the
previous sentence to enforce the provisions of this Section 10(c), and the
Purchaser agrees to promptly do so.

                           (vi)     The foregoing right of first refusal shall
terminate 180 days after the Purchaser's initial public offering under the
Securities Act of 1933, as amended (the "RIGHTS TERMINATION DATE"). Following
the Rights Termination Date, WPN shall be permitted to Transfer the Purchaser
Common Stock, provided that any such transfer shall be of at least 10,000
shares.

         10.2     PUBLICITY. Each of the Purchaser and the Sellers shall ensure
that, after the Closing Date: (a) neither it nor any of its Representatives
issue or disseminate any press release or other publicity or otherwise make any
disclosure of any nature (to any other Person) regarding any of the Transactions
or the existence or terms of this Agreement without the prior written consent of
the other party (which consent shall not be unreasonably withheld), except (1)
to the extent that the it is required by law to make any such disclosure; (2)
that it may disclose the foregoing to potential investors who sign appropriate
confidentiality agreements; and (3) to its Representatives; and (b) if it is
required by law to make any such disclosure, it advises the other parties to the
extent possible, at least two business days before making such disclosure, of
the nature and content of the intended disclosure.

         10.3     FURTHER ASSURANCES. Each party hereto shall execute and/or
cause to be delivered to each other party hereto such instruments and other
documents, and shall take such

                                       34
<PAGE>   40
other actions, as such other party may reasonably request (prior to, at or after
the Closing) for the purpose of carrying out or evidencing any of the
Transactions.

         10.4     FEES AND EXPENSES. Each party hereto shall bear and pay all of
its own fees, costs and expenses that have been incurred or that are in the
future incurred by, on behalf of, or for the benefit of it in connection with
negotiation of, due diligence for, consummation of, and performance of the
Transactions.

         10.5     ATTORNEYS' FEES. If any legal action or other legal proceeding
relating to any of the Transactional Agreements or the enforcement of any
provision of any of the Transactional Agreements is brought against any party to
this Agreement, the prevailing party shall be entitled to recover reasonable
attorneys' fees, costs and disbursements (in addition to any other relief to
which the prevailing party may be entitled).

         10.6     NOTICES. Any notice or other communication required or
permitted to be delivered to any party under this Agreement shall be in writing
and shall be deemed properly delivered, given and received when delivered (by
hand, by registered mail, by courier or express delivery service or by
facsimile) to the address or facsimile telephone number set forth beneath the
name of such party below (or to such other address or facsimile telephone number
as such party shall have specified in a written notice given to the other

to this Agreement or the enforcement of any provision of this Agreement may be
brought or otherwise commenced in any state or federal court located in Salt

                           (i)      expressly and irrevocably consents and
submits to the jurisdiction of each state and federal court located in Salt Lake
County, Utah (and each appellate court located in the State of Utah) in
connection with any such legal proceeding;

                           (ii)     agrees that each state and federal court
located in Salt Lake County, Utah shall be deemed to be a convenient forum; and

                           (iii)    agrees not to assert (by way of motion, as a
defense or otherwise), in any such legal proceeding commenced in any state or
federal court located in Salt Lake County, Utah, any claim that such party is
not subject personally to the jurisdiction of such court, that such legal
proceeding has been brought in an inconvenient forum, that the

                                       36
<PAGE>   42
         venue of such proceeding is improper or that this Agreement or the
         subject matter of this Agreement may not be enforced in or by such
         court.

                  (c)      Each party hereto agrees that, if any Proceeding is

<PAGE>   43
                  (d)      Notwithstanding anything to the contrary herein, the
parties hereto agree that each party would be unduly damaged by the rescission

shall preclude any other or further exercise thereof or of any other power,
right, privilege or remedy.

                  (b)      No Person shall be deemed to have waived any claim
arising out of this Agreement, or any power, right, privilege or remedy under
this Agreement, unless the waiver of such claim, power, right, privilege or
remedy is expressly set forth in a written instrument duly executed and
delivered on behalf of such Person; and any such waiver shall not be applicable
or have any effect except in the specific instance in which it is given.

         10.14    AMENDMENTS. This Agreement may not be amended, modified,
altered or supplemented other than by means of a written instrument duly
executed and delivered on behalf of the Purchaser and the Sellers.

         10.15    SEVERABILITY. In the event that any provision of this
Agreement, or the application of any such provision to any Person or set of

which it is determined to be invalid, unlawful, void or unenforceable, shall not
be impaired or otherwise affected and shall continue to be valid and enforceable
to the fullest extent permitted by law.

         10.16    ENTIRE AGREEMENT. The Transactional Agreements set forth the
entire understanding of the parties relating to the subject matter thereof and
supersede all prior agreements and understandings among or between any of the
parties relating to the subject matter thereof.
