                                 CIDERA, INC.
                          2000 EQUITY INCENTIVE PLAN

                            STOCK OPTION AGREEMENT
                  (INCENTIVE AND NONSTATUTORY STOCK OPTIONS)

     Pursuant to your Stock Option Grant Notice ("Grant Notice") and this Stock
Option Agreement, Cidera, Inc. (the "Company") has granted you an option under
its 2000 Equity Incentive Plan (the "Plan") to purchase the number of shares of
the Company's Common Stock indicated in your Grant Notice at the exercise price
indicated in your Grant Notice. Defined terms not explicitly defined in this
Stock Option Agreement but defined in the Plan shall have the same definitions
as in the Plan.

     The details of your option are as follows:

     1.   Vesting.  Subject to the limitations contained herein, your option
will vest as provided in your Grant Notice, provided that vesting will cease
upon the earlier of (i) the date of a violation on your part of any proprietary
information, inventions, non-solicitation and/or non-competition agreements that
exist between you and the Company, or (ii) termination of your Continuous
Service.

     2.   Number of Shares and Exercise Price.  The number of shares of Common
Stock subject to your option and your exercise price per share referenced in
your Grant Notice may be adjusted from time to time for Capitalization
Adjustments, as provided in the Plan.

     3.   Exercise prior to Vesting ("Early Exercise").  If permitted in your
Grant Notice (i.e., the "Exercise Schedule" indicates that "Early Exercise" of
your option is permitted) and subject to the provisions of your option, you may
elect at any time that is both (i) during the period of your Continuous Service
and (ii) during the term of your option, to exercise all or part of your option,
including the nonvested portion of your option; provided, however, that:

          (a)  a partial exercise of your option shall be deemed to cover first
vested shares of Common Stock and then the earliest vesting installment of
unvested shares of Common Stock;

          (b)  any shares of Common Stock so purchased from installments that
have not vested as of the date of exercise shall be subject to the purchase
option in favor of the Company as described in the Company's form of Early
Exercise Stock Purchase Agreement; and

          (c)  you shall enter into the Company's form of Early Exercise Stock
Purchase Agreement with a vesting schedule that will result in the same vesting
as if no early exercise had occurred.
<PAGE>

     4.   ISO Exercise Limitation.

          (a)  The aggregate Fair Market Value of the shares of Common Stock
with respect to which you may exercise your option for the first time during any
calendar year, when added to the aggregate Fair Market Value of the shares of
Common Stock subject to any other options designated as Incentive Stock Options
and granted to you under any stock option plan of the Company or an Affiliate
prior to the Date of Grant with respect to which such options are exercisable
for the first time during the same calendar year, shall not exceed $100,000 (the
"ISO Exercise Limitation") unless applicable law requires that your option be
exercisable sooner./1/

          (b)  Notwithstanding the provisions of paragraph 4(a), if the ISO
Exercise Limitation would prevent you from exercising your option as to vested
shares, then the ISO Exercise Limitation shall terminate as to such vested
shares as such shares vest, and you may exercise your option as to such vested
shares. Upon such termination of the ISO Exercise Limitation, your option shall
be deemed a Nonstatutory Stock Option to the extent of the number of vested
shares of Common Stock subject to your option that would otherwise exceed the
ISO Exercise Limitation.

          (c)  The ISO Exercise Limitation shall terminate, and you may fully
exercise your option, as to all shares of Common Stock subject to your option
for which your option would have been exercisable in the absence of the ISO
Exercise Limitation upon the earlier of the following events:

               (i)   the date of termination of your Continuous Service,

               (ii)  the day immediately prior to the effective date of a Change
in Control (as defined in the Plan) in which your option is not assumed or
substituted for as provided in the Plan, or

               (iii) the day that is ten (10) days prior to the Expiration Date
of your option.

Upon such termination of the ISO Exercise Limitation, your option shall be
deemed a Nonstatutory Stock Option to the extent of the number of shares of
Common Stock subject to your option that would otherwise then exceed the ISO
Exercise Limitation.

     5.   Method of Payment. Payment of the exercise price is due in full upon
exercise of all or any part of your option. You may elect to make payment of the
exercise price in cash or by check or in any other manner permitted by your
Grant Notice, which may include one or more of the following:

__________________________
/1/  For purposes of this provision, your options designated as Incentive Stock
Options shall be taken into account in the order in which they were granted to
you, and the Fair Market Value of shares of Common Stock shall be determined as
of the time the option with respect to such shares of Common Stock is granted.
If Section 422 of the Code is amended to provide for a different limitation from
that set forth in this provision, the ISO Exercise Limitation shall be deemed
amended effective as of the date required or permitted by such amendment to the
Code.

                                      2.
<PAGE>

          (a)  In the Company's sole discretion at the time your option is
exercised and provided that at the time of exercise the Common Stock is publicly
traded and quoted regularly in The Wall Street Journal, pursuant to a program
developed under Regulation T as promulgated by the Federal Reserve Board that,
prior to the issuance of Common Stock, results in either the receipt of cash (or
check) by the Company or the receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds.

          (b)  Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, by delivery of
already-owned shares of Common Stock either that you have held for the period
required to avoid a charge to the Company's reported earnings (generally six
months) or that you did not acquire, directly or indirectly from the Company,
that are owned free and clear of any liens, claims, encumbrances or security
interests, and that are valued at Fair Market Value on the date of exercise.
"Delivery" for these purposes, in the sole discretion of the Company at the time
you exercise your option, shall include delivery to the Company of your
attestation of ownership of such shares of Common Stock in a form approved by
the Company. Notwithstanding the foregoing, you may not exercise your option by
tender to the Company of Common Stock to the extent such tender would violate
the provisions of any law, regulation or agreement restricting the redemption of
the Company's stock.

          (c)  Pursuant to the following deferred payment alternative:

               (i)   Not less than one hundred percent (100%) of the aggregate
exercise price, plus accrued interest, shall be due four (4) years from date of
exercise or, at the Company's election, upon termination of your Continuous
Service.

               (ii)  Interest shall be compounded at least annually and shall be
charged at the minimum rate of interest necessary to avoid the treatment as
interest, under any applicable provisions of the Code, of any portion of any
amounts other than amounts stated to be interest under the deferred payment
arrangement.

               (iii) At any time that the Company is incorporated in Delaware,
payment of the Common Stock's "par value," as defined in the Delaware General
Corporation Law, shall be made in cash and not by deferred payment.

               (iv)  In order to elect the deferred payment alternative, you
must, as a part of your written notice of exercise, give notice of the election
of this payment alternative and, in order to secure the payment of the deferred
exercise price to the Company hereunder, if the Company so requests, you must
tender to the Company a promissory note and a security agreement covering the
purchased shares of Common Stock, both in form and substance satisfactory to the
Company, or such other or additional documentation as the Company may request.

     6.   Whole Shares.  You may exercise your option only for whole shares of
Common Stock.

                                      3.
<PAGE>

     7.   Securities Law Compliance.  Notwithstanding anything to the contrary
contained herein, you may not exercise your option unless the shares of Common
Stock issuable upon such exercise are then registered under the Securities Act
or, if such shares of Common Stock are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act.  The exercise of your option must also
comply with other applicable laws and regulations governing your option, and you
may not exercise your option if the Company determines that such exercise would
not be in material compliance with such laws and regulations.

     8.   Term.  You may not exercise your option before the commencement of its
term or after its term expires.  The term of your option commences on the Date
of Grant and expires upon the earliest of the following:

          (a)  three (3) months after the termination of your Continuous Service
for any reason other than your Disability or death, provided that if during any
part of such three- (3-) month period your option is not exercisable solely
because of the condition set forth in the preceding paragraph relating to
"Securities Law Compliance," your option shall not expire until the earlier of
the Expiration Date or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of your Continuous Service;

          (b)  twelve (12) months after the termination of your Continuous
Service due to your Disability;

          (c)  eighteen (18) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates;

          (d)  the date of a violation on your part of the terms of any
proprietary information, inventions, non-solicitation and/or non-competition
agreements that exist between you and the Company;

          (e)  the Expiration Date indicated in your Grant Notice; or

          (f)  the day before the tenth (10th) anniversary of the Date of Grant.

     If your option is an incentive stock option, note that, to obtain the
federal income tax advantages associated with an "incentive stock option," the
Code requires that at all times beginning on the date of grant of your option
and ending on the day three (3) months before the date of your option's
exercise, you must be an employee of the Company or an Affiliate, except in the
event of your death or Disability. The Company has provided for extended
exercisability of your option under certain circumstances for your benefit but
cannot guarantee that your option will necessarily be treated as an "incentive
stock option" if you continue to provide services to the Company or an Affiliate
as a Consultant or Director after your employment terminates or if you otherwise
exercise your option more than three (3) months after the date your employment
terminates.

                                      4.
<PAGE>

     9.   Exercise.

          (a)  You may exercise the vested portion of your option (and the
unvested portion of your option if your Grant Notice so permits) during its term
by delivering a Notice of Exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require.

          (b)  By exercising your option you agree that, as a condition to any
exercise of your option, the Company may require you to enter into an
arrangement providing for the payment by you to the Company of any tax
withholding obligation of the Company arising by reason of (1) the exercise of
your option, (2) the lapse of any substantial risk of forfeiture to which the
shares of Common Stock are subject at the time of exercise, or (3) the
disposition of shares of Common Stock acquired upon such exercise.

          (c)  If your option is an incentive stock option, by exercising your
option you agree that you will notify the Company in writing within fifteen (15)
days after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of your option that occurs within two (2) years after the
date of your option grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of your option.

          (d)  By exercising your option you agree that the Company (or a
representative of the underwriter(s)) may, in connection with the first
underwritten registration of the offering of any securities of the Company under
the Securities Act, require that you not sell, dispose of, transfer, make any
short sale of, grant any option for the purchase of, or enter into any hedging
or similar transaction with the same economic effect as a sale, any shares of
Common Stock or other securities of the Company held by you, for a period of
time specified by the underwriter(s) (not to exceed one hundred eighty (180)
days) following the effective date of the registration statement of the Company
filed under the Securities Act.  You further agree to execute and deliver such
other agreements as may be reasonably requested by the Company and/or the
underwriter(s) that are consistent with the foregoing or that are necessary to
give further effect thereto.  In order to enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to your shares of
Common Stock until the end of such period.

     10.  Transferability. Your option is not transferable, except by will or by
the laws of descent and distribution, and is exercisable during your life only
by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise your
option.

     11.  Right of First Refusal. Shares of Common Stock that you acquire upon
exercise of your option are subject to the right of first refusal described
below.  The Company's right of first refusal shall expire on the Listing Date as
defined in the Plan.

          (a)  Prior to the Listing Date, you may not validly transfer (as
hereinafter defined) any shares of stock purchased on exercise of the option, or
any interest in such shares,

                                      5.
<PAGE>

unless such transfer is solely for cash consideration and is made in compliance
with the following provisions:

               (i)   Before there can be a valid transfer of any shares or any
interest therein, the record holder of the shares to be transferred (the
"Offered Shares") shall give written notice (by registered or certified mail) to
the Company. Such notice shall specify the identity of the proposed transferee,
the cash price offered for the Offered Shares by the proposed transferee and the
other terms and conditions of the proposed transfer. The date such notice is
mailed shall be hereinafter referred to as the "notice date" and the record
holder of the Offered Shares shall be hereinafter referred to as the "Offeror."
If, from time to time, there is any stock dividend, stock split or other change
in the character or amount of any of the outstanding stock of the corporation
the stock of which is subject to the provisions of this option, then in such
event any and all new, substituted or additional securities to which you are
entitled by reason of your ownership of the shares acquired upon exercise of
this option shall be immediately subject to the Company's Right of First Refusal
with the same force and effect as the shares subject to the Right of First
Refusal immediately before such event.

               (ii)  For a period of thirty (30) calendar days after the notice
date, the Company shall have the option to purchase all (but not less than all)
of the Offered Shares at the purchase price and on the terms set forth in
subsection 11(a)(iii) ("Right of First Refusal"). The Company may exercise its
Right of First Refusal by mailing (by registered or certified mail) written
notice of exercise of its Right of First Refusal to the Offeror prior to the end
of said thirty (30) days.

               (iii) The price at which the Company may purchase the Offered
Shares pursuant to the exercise of its Right of First Refusal shall be the cash
price offered for the Offered Shares by the proposed transferee (as set forth in
the notice required under subsection 11(a)(i)).  The Company's notice of
exercise of its Right of First Refusal shall be accompanied by full payment for
the Offered Shares and, upon such payment by the Company, the Company shall
acquire full right, title and interest to all of the Offered Shares.

               (iv)  If, and only if, the option given pursuant to subsection
11(a)(ii) is not exercised, the transfer proposed in the notice given pursuant
to subsection 11(a)(i) may take place; provided, however, that such transfer
must, in all respects, be exactly as proposed in said notice except that such
transfer may not take place either before the tenth (10th) calendar day after
the expiration of said 30-day option exercise period or after the ninetieth
(90th) calendar day after the expiration of said 30-day option exercise period,
and if such transfer has not taken place prior to said ninetieth (90th) day,
such transfer may not take place without once again complying with subsection
11(a).

          (b)  As used in this Section 11, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution.

                                      6.
<PAGE>

          (c)  None of the shares of the Company's stock purchased on exercise
of this option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 11 have been complied with
in all respects. The certificates of stock evidencing shares of stock purchased
on exercise of this option shall bear an appropriate legend referring to the
transfer restrictions imposed by this Section 11.

          (d)  To ensure that shares subject to the Company's Right of First
Refusal will be available for repurchase by the Company, the Company may require
you to deposit the certificate(s) evidencing the shares that you purchase upon
exercise of this option with an escrow agent designated by the Company under the
terms and conditions of an escrow agreement approved by the Company. If the
Company does not require such deposit as a condition of exercise of your option,
the Company reserves the right at any time to require you to so deposit the
certificate(s) in escrow. As soon as practicable after the expiration of the
Company's Right of First Refusal, the agent shall deliver to you the shares and
any other property no longer subject to such restriction. In the event the
shares and any other property held in escrow are subject to the Company's
exercise of its Right of First Refusal, the notices required to be given to you
shall be given to the escrow agent, and any payment required to be given to you
shall be given to the escrow agent. Within thirty (30) days after payment by the
Company for the Offered Shares, the escrow agent shall deliver the Offered
Shares that the Company has repurchased to the Company and shall deliver the
payment received from the Company to you.

     12.  Right of Repurchase.

          (a)  The Company shall have the right to repurchase all or any part of
the shares received pursuant to the exercise of your option (a "Repurchase
Right") on the terms and conditions below.

          (b)  The Company may elect (but is not obligated) to repurchase all or
any part of the vested and unvested shares you received pursuant to this option
(the Company's "Repurchase Right"). If, from time to time, there is any stock
dividend, stock split or other change in the character or amount of any of the
outstanding stock of the corporation the stock of which is subject to the
provisions of this option, then in such event any and all new, substituted or
additional securities to which you are entitled by reason of your ownership or
the shares acquired upon exercise of this option shall be immediately subject to
this Repurchase Right with the same force and effect as the shares subject to
this Repurchase Right immediately before such event.

          (c)  The Company's Repurchase Right shall be exercisable only within
the ninety (90) day period following a Repurchase Event, or such longer period
as may be required to avoid a charge to earnings for financial accounting
purposes or as otherwise agreed to by the Company and you (the "Repurchase
Period"). Each of the following events shall constitute a "Repurchase Event":

               (i)  Termination of your Continuous Service for any reason or no
reason, with or without cause, including death or Disability, in which event the
Repurchase

                                      7.
<PAGE>

Period shall commence on the date of termination of your Continuous Service (or
in the case of a post-termination exercise of this option, the date of such
exercise).

               (ii)  You, your legal representative, or other holder of shares
acquired upon exercise of this option attempts to sell, exchange, transfer,
pledge, or otherwise dispose of any of the shares without prior written approval
of the Company, in which event the Repurchase Period shall commence on the date
the Company receives actual notice of such attempted sale, exchange, transfer,
pledge or other disposition.

               (iii) The receivership, bankruptcy, or other creditor's
proceeding regarding you or the taking of any of the shares by legal process,
such as a levy of execution, in which event the Repurchase Period shall commence
on the date the Company receives actual notice of the commencement of pendency
of the receivership, bankruptcy or other creditor's proceeding or the date of
such taking, as the case may be, and the Fair Market Value of the shares shall
be determined as of the last day of the month preceding the month in which the
proceeding involved commenced or the taking occurred.

               (iv)  A violation by you of any proprietary information,
inventions, non-solicitation and/or non-competition agreements that exist
between you and the Company.

          (d)  The Company shall not exercise its Repurchase Right after the
Listing Date as defined in the Plan, except it may do so after the Listing Date
if there is a Repurchase Event described in Section 12(c)(iv) above. The Company
shall not exercise its Repurchase Right for less than all of the shares without
your consent, shall exercise its Repurchase Right only for cash or cancellation
of purchase money indebtedness for the shares and shall give you written notice
(accompanied by payment for the shares) within ninety (90) calendar days after
the later of the Repurchase Event or a proper purchase of shares following such
Repurchase Event.

          (e)  The repurchase price for vested shares shall be equal to the
shares' Fair Market Value at the time of the Repurchase Event, except for a
Repurchase Event described in Section 12(c)(iv) above in which case the Company
shall repurchase vested shares at a price equal to your exercise price for such
shares as indicated in your Stock Option Grant Notice. In all events, the
Company shall repurchase unvested shares at a price equal to your exercise price
for those shares as indicated in your Stock Option Grant Notice.

          (f)  To ensure that the shares subject to the Company's Repurchase
Right will be available for repurchase, the Company may require you to deposit
the certificate evidencing the shares that you purchase upon exercise of this
option with an agent designated by the Company under the terms and conditions of
an escrow agreement approved by the Company. If the Company does not require
such deposit as a condition of exercise of this option, the Company reserves the
right at any time to require you to so deposit the certificate in escrow. As
soon as practicable after the expiration of this Repurchase Right, the agent
shall deliver to you the shares and any other property no longer subject to such
restriction. In the event the shares and any other property held in escrow are
subject to the Company's exercise of its Repurchase Right, the notices required
to be given to you shall be given to the escrow agent, and any

                                      8.
<PAGE>

payment required to be given to you shall be given to the escrow agent. Within
thirty (30) days after payment by the Company for the shares, the escrow agent
shall deliver the shares that the Company has purchased to the Company and shall
deliver the payment received from the Company to you.

     13.  Forfeiture Of Profits From Sale Of Option Shares. If you engage in any
activity or conduct in violation of any proprietary information, inventions,
non-solicitation and/or non-competition agreements that exist between you and
the Company, you agree to pay to the Company in cash or a cash equivalent
acceptable to the Company an amount equal to any profits you receive from the
sale of the shares subject to this option, whether any such sale occurs during
or after the period of your Continuous Service for the Company or before or
after the conduct occurs that violates the terms of your agreements with the
Company. The amount of your profits for these purposes will be calculated as the
difference between the sale price for the shares and the price you paid to
exercise the option. There shall be no offset from the amount you owe the
Company for any tax liability you may have incurred as a result of the exercise
of the option or the sale of the shares. You agree to make this payment to the
Company no later than thirty (30) days after the date the Company requests
payment. You also consent to a deduction from any amounts the Company owes you
from time to time (including amounts owed to you as wages or other compensation,
fringe benefits, or vacation pay, as well as any other amounts owed to you by
the Company) to the extent of the amount you are obligated to pay the Company
under this Section. Whether or not the Company elects to make any set-off in
whole or part, if the Company does not recover by means of set-off the full
amount you owe it, you agree to pay the unpaid balance within the time period
specified above.

     14.  Option not a Service Contract. Your option is not an employment or
service contract, and nothing in your option shall be deemed to create in any
way whatsoever any obligation on your part to continue in the employ of the
Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option shall obligate the Company or an
Affiliate, their respective shareholders, Boards of Directors, Officers or
Employees to continue any relationship that you might have as a Director or
Consultant for the Company or an Affiliate.

     15.  Withholding Obligations.

          (a)  At the time you exercise your option, in whole or in part, or at
any time thereafter as requested by the Company, you hereby authorize
withholding from payroll and any other amounts payable to you, and otherwise
agree to make adequate provision for (including by means of a "cashless
exercise" pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Company or an Affiliate, if any, which arise in connection
with your option.

          (b)  Upon your request and subject to approval by the Company, in its
sole discretion, and compliance with any applicable conditions or restrictions
of law, the Company may withhold from fully vested shares of Common Stock
otherwise issuable to you upon the exercise of your option a number of whole
shares of Common Stock having a Fair Market Value,

                                      9.
<PAGE>

determined by the Company as of the date of exercise, not in excess of the
minimum amount of tax required to be withheld by law. If the date of
determination of any tax withholding obligation is deferred to a date later than
the date of exercise of your option, share withholding pursuant to the preceding
sentence shall not be permitted unless you make a proper and timely election
under Section 83(b) of the Code, covering the aggregate number of shares of
Common Stock acquired upon such exercise with respect to which such
determination is otherwise deferred, to accelerate the determination of such tax
withholding obligation to the date of exercise of your option. Notwithstanding
the filing of such election, shares of Common Stock shall be withheld solely
from fully vested shares of Common Stock determined as of the date of exercise
of your option that are otherwise issuable to you upon such exercise. Any
adverse consequences to you arising in connection with such share withholding
procedure shall be your sole responsibility.

          (c)  You may not exercise your option unless the tax withholding
obligations of the Company and/or any Affiliate are satisfied. Accordingly, you
may not be able to exercise your option when desired even though your option is
vested, and the Company shall have no obligation to issue a certificate for such
shares of Common Stock or release such shares of Common Stock from any escrow
provided for herein.

     16.  Notices. Any notices provided for in your option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by mail by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.

     17.  Governing Plan Document. Your option is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your option, and
is further subject to all interpretations, amendments, rules and regulations
which may from time to time be promulgated and adopted pursuant to the Plan. In
the event of any conflict between the provisions of your option and those of the
Plan, the provisions of the Plan shall control.

                          Adopted: February 24, 2000

                  Approved By Stockholders: February 24, 2000

                       Effective Date: February 24, 2000

1.   Purposes.

     (a)  Eligible Option Recipients. The persons eligible to receive Options
are the Non-Employee Directors of the Company.

     (b)  Available Options. The purpose of the Plan is to provide a means by
which Non-Employee Directors may be given an opportunity to benefit from
increases in value of the Common Stock through the granting of Nonstatutory
Stock Options.

     (c)  General Purpose. The Company, by means of the Plan, seeks to retain
the services of its Non-Employee Directors, to secure and retain the services of
new Non-Employee Directors and to provide incentives for such persons to exert
maximum efforts for the success of the Company and its Affiliates.

2.   Definitions.

     (a)  "Affiliate" means any parent corporation or subsidiary corporation of
the Company, whether now or hereafter existing, as those terms are defined in
Sections 424(e) and (f), respectively, of the Code.

     (b)  "Annual Grant" means an Option granted annually to all Non-Employee
Directors who meet the criteria specified in subsection 6(b) of the Plan.

     (c)  "Annual Meeting" means the annual meeting of the stockholders of the
Company.

term "Consultant" shall not include either Directors of the Company who are not
compensated by the Company for their services as Directors or Directors of the
Company who are merely paid a director's fee by the Company for their services
as Directors.

     (i)  "Continuous Service" means that the Optionholder's service with the
Company or an Affiliate, whether as an Employee, Director or Consultant, is not

the Optionholder renders service to the Company or an Affiliate as an Employee,
Consultant or Director or a change in the entity for which the Optionholder
renders such service, provided that there is no interruption or termination of
the Optionholder's Continuous Service.  For example, a change in status from a

Employee of the Company will not constitute an interruption of Continuous
Service.  The Board or the chief executive officer of the Company, in that
party's sole discretion, may determine whether Continuous Service shall be
considered interrupted in the case of any leave of absence approved by that
party, including sick leave, military leave or any other personal leave.

an Affiliate.

     (n)  "Fair Market Value" means, as of any date, the value of the Common
Stock determined as follows:

          (i)    If the Common Stock is listed on any established stock exchange
or traded on the Nasdaq National Market or the Nasdaq SmallCap Market, the Fair
Market Value of a share of Common Stock shall be the closing sales price for
such stock (or the closing bid, if no sales were reported) as quoted on such
exchange or market (or the exchange or market with the greatest volume of
trading in the Common Stock) on the last market trading day prior to the day of
determination, as reported in The Wall Street Journal or such other source as
the Board deems reliable.

          (ii)   In the absence of such markets for the Common Stock, the Fair

an Optionholder evidencing the terms and conditions of an individual Option
grant. Each Option Agreement shall be subject to the terms and conditions of the
Plan.

     (v)  "Optionholder" means a person to whom an Option is granted pursuant to
the Plan or, if applicable, such other person who holds an outstanding Option.

     (w)  "Plan" means this Cidera, Inc. 2000 Non-Employee Directors' Stock

specified in the Plan.

          (ii) To construe and interpret the Plan and Options granted under it,
and to establish, amend and revoke rules and regulations for its administration.
The Board, in the

                                      3.
<PAGE>

exercise of this power, may correct any defect, omission or inconsistency in the
Plan or in any Option Agreement, in a manner and to the extent it shall deem
necessary or expedient to make the Plan fully effective.

          (iii)  To amend the Plan or an Option as provided in Section 12.

          (iv)   Generally, to exercise such powers and to perform such acts as
the Board deems necessary or expedient to promote the best interests of the
Company that are not in conflict with the provisions of the Plan.

     (c)  Effect of Board's Decision. All determinations, interpretations and
constructions made by the Board in good faith shall not be subject to review by
any person and shall be final, binding and conclusive on all persons.

4.   Shares Subject to the Plan.

     (a)  Share Reserve.  Subject to the provisions of Section 11 relating to
adjustments upon changes in the Common Stock, the Common Stock that may be
issued pursuant to Options shall not exceed in the aggregate four hundred
thousand (400,000) shares of Common Stock.

     (b)  Reversion of Shares to the Share Reserve.  If any Option shall for any
reason expire or otherwise terminate, in whole or in part, without having been
exercised in full, the shares of Common Stock not acquired under such Option
shall revert to and again become available for issuance under the Plan.

     (c)  Source of Shares.  The shares of Common Stock subject to the Plan may
be unissued shares or reacquired shares, bought on the market or otherwise.

automatically shall be granted an Initial Grant to purchase forty thousand
(40,000) shares of Common Stock on the terms and conditions set forth herein.

          (ii) After the IPO Date, each person who is elected or appointed for
the first time to be a Non-Employee Director automatically shall, upon the date
of his or her initial election or appointment to be a Non-Employee Director by
the Board or stockholders of the Company, be granted an Initial Grant to
purchase forty thousand (40,000) shares of Common Stock on the terms and
conditions set forth herein.

                                      4.
<PAGE>

     (b) Annual Grants. Without any further action of the Board, a Non-Employee
Director shall be granted an Annual Grant as follows: On the day following each
Annual Meeting commencing with the Annual Meeting in 2001, each person who is
then a Non-Employee Director automatically shall be granted an Annual Grant to
purchase ten thousand (10,000) shares of Common Stock on the terms and
conditions set forth herein; provided, however, that if the person has not been
serving as a Non-Employee Director for the entire period since the preceding
Annual Meeting, then the number of shares subject to the Annual Grant shall be
reduced pro rata for each full quarter prior to the date of grant during which
such person did not serve as a Non-Employee Director.

7.   Option Provisions.

     Each Option shall be in such form and shall contain such terms and
conditions as required by the Plan.  Each Option shall contain such additional
terms and conditions, not inconsistent with the Plan, as the Board shall deem
appropriate.  Each Option shall include (through incorporation of provisions
hereof by reference in the Option or otherwise) the substance of each of the
following provisions:

     (a)  Term.  No Option shall be exercisable after the expiration of ten (10)
years from the date it was granted.

     (b)  Exercise Price. The exercise price of each Option shall be one hundred
percent (100%) of the Fair Market Value of the stock subject to the Option on
the date the Option is granted. Notwithstanding the foregoing, an Option may be
granted with an exercise price lower than that set forth in the preceding
sentence if such Option is granted pursuant to an assumption or substitution for
another option in a manner satisfying the provisions of Section 424(a) of the
Code.

     (c)  Consideration. The purchase price of stock acquired pursuant to an
Option may be paid, to the extent permitted by applicable statutes and
regulations, in any combination of the following methods:

          (i)   By cash or check.

          (ii)  Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, by delivery of
already-owned shares of Common Stock either that the Optionholder has held for
the period required to avoid a charge to the Company's reported earnings
(generally six months) or that the Optionholder did not acquire, directly or
indirectly from the Company, that are owned free and clear of any liens, claims,
encumbrances or security interests, and that are valued at Fair Market Value on
the date of exercise. "Delivery" for these purposes shall include delivery to
the Company of the Optionholder's attestation of ownership of such shares of
Common Stock in a form approved by the Company. Notwithstanding the foregoing,
the Optionholder may not exercise the Option by tender to the Company of Common
Stock to the extent such tender would violate the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock.

                                      5.
<PAGE>

          (iii)  Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, pursuant to a
program developed under Regulation T as promulgated by the Federal Reserve Board
that, prior to the issuance of Common Stock, results in either the receipt of
cash (or check) by the Company or the receipt of irrevocable instructions to pay
the aggregate exercise price to the Company from the sales proceeds.

     (d)  Transferability.  An Option is transferable by will or by the laws of
descent and distribution. An Option shall be exercisable during the lifetime of
the Optionholder only by the Optionholder.  However, the Optionholder may, by
delivering written notice to the Company, in a form satisfactory to the Company,
designate a third party who, in the event of the death of the Optionholder,
shall thereafter be entitled to exercise the Option.

     (e)  Exercise Schedule.  The Option shall be exercisable as the shares of
Common Stock subject to the Option vest.

     (f)  Vesting Schedule. Options shall vest as follows:

          (i)  Initial Grants shall provide for vesting of fifty percent (50%)
of the shares of Common Stock subject to the Option twelve (12) months after the
date of the grant of the Option and fifty percent (50%) of the shares of Common
Stock subject to the Option twenty-four (24) months after the date of grant of
the option.

          (ii) Annual Grants shall provide for vesting of one hundred percent
(100%) of the shares of Common Stock subject to the Option twelve (12) months
after the date of the grant.

     (g)  Termination of Continuous Service.  In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or
Disability), the Optionholder may exercise his or her Option (to the extent that
the Optionholder was entitled to exercise it as of the date of termination) but
only within such period of time ending on the earlier of (i) the date three (3)
months following the termination of the Optionholder's Continuous Service, or
(ii) the expiration of the term of the Option as set forth in the Option
Agreement.  If, after termination, the Optionholder does not exercise his or her
Option within the time specified in the Option Agreement, the Option shall
terminate.

     (h)  Extension of Termination Date. If the exercise of the Option following
the termination of the Optionholder's Continuous Service (other than upon the
Optionholder's death or Disability) would be prohibited at any time solely
because the issuance of shares would violate the registration requirements under
the Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in subsection 7(a) or (ii) the
expiration of a period of three (3) months after the termination of the
Optionholder's Continuous Service during which the exercise of the Option would
not be in violation of such registration requirements.

     (i)  Disability of Optionholder.  In the event an Optionholder's Continuous
Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her

                                      6.
<PAGE>

Option (to the extent that the Optionholder was entitled to exercise it as of
the date of termination), but only within such period of time ending on the
earlier of (i) the date twelve (12) months following such termination or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, after termination, the Optionholder does not exercise his or her Option
within the time specified herein, the Option shall terminate.

     (j)  Death of Optionholder. In the event (i) an Optionholder's Continuous
Service terminates as a result of the Optionholder's death or (ii) the
Optionholder dies within the three-month period after the termination of the
Optionholder's Continuous Service for a reason other than death, then the Option
may be exercised (to the extent the Optionholder was entitled to exercise the
Option as of the date of death) by the Optionholder's estate, by a person who
acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the Option upon the Optionholder's death, but only
within the period ending on the earlier of (1) the date eighteen (18) months
following the date of death or (2) the expiration of the term of such Option as
set forth in the Option Agreement. If, after death, the Option is not exercised
within the time specified herein, the Option shall terminate.

8.   Covenants of the Company.

     (a)  Availability of Shares.  During the terms of the Options, the Company
shall keep available at all times the number of shares of Common Stock required
to satisfy such Options.

     (b)  Securities Law Compliance.  The Company shall seek to obtain from each
regulatory commission or agency having jurisdiction over the Plan such authority
as may be required to grant Options and to issue and sell shares of Common Stock
upon exercise of the Options; provided, however, that this undertaking shall not
require the Company to register under the Securities Act the Plan, any Option or
any stock issued or issuable pursuant to any such Option.  If, after reasonable
efforts, the Company is unable to obtain from any such regulatory commission or
agency the authority which counsel for the Company deems necessary for the
lawful issuance and sale of stock under the Plan, the Company shall be relieved
from any liability for failure to issue and sell stock upon exercise of such
Options unless and until such authority is obtained.

9.   Use of Proceeds from Stock.

     Proceeds from the sale of stock pursuant to Options shall constitute
general funds of the Company.

10.  Miscellaneous.

     (a)  Stockholder Rights. No Optionholder shall be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares subject
to such Option unless and until such Optionholder has satisfied all requirements
for exercise of the Option pursuant to its terms.

                                      7.
<PAGE>

     (b)  No Service Rights.  Nothing in the Plan or any instrument executed or
Option granted pursuant thereto shall confer upon any Optionholder any right to
continue to serve the Company as a Non-Employee Director or shall affect the
right of the Company or an Affiliate to terminate (i) the employment of an
Employee with or without notice and with or without cause, (ii) the service of a
Consultant pursuant to the terms of such Consultant's agreement with the Company
or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the
Company or an Affiliate, and any applicable provisions of the corporate law of
the state in which the Company or the Affiliate is incorporated, as the case may
be.

     (c)  Investment Assurances.  The Company may require an Optionholder, as a
condition of exercising or acquiring stock under any Option, (i) to give written
assurances satisfactory to the Company as to the Optionholder's knowledge and
experience in financial and business matters and/or to employ a purchaser
representative reasonably satisfactory to the Company who is knowledgeable and
experienced in financial and business matters and that he or she is capable of
evaluating, alone or together with the purchaser representative, the merits and
risks of exercising the Option; and (ii) to give written assurances satisfactory
to the Company stating that the Optionholder is acquiring the stock subject to
the Option for the Optionholder's own account and not with any present intention
of selling or otherwise distributing the stock.  The foregoing requirements, and
any assurances given pursuant to such requirements, shall be inoperative if
(iii) the issuance of the shares upon the exercise or acquisition of stock under
the Option has been registered under a then currently effective registration
statement under the Securities Act or (iv) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws.  The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the stock.

     (d)  Withholding Obligations. The Optionholder may satisfy any federal,
state or local tax withholding obligation relating to the exercise or
acquisition of stock under an Option by any of the following means (in addition
to the Company's right to withhold from any compensation paid to the
Optionholder by the Company) or by a combination of such means: (i) tendering a
cash payment; (ii) authorizing the Company to withhold shares from the shares of
the Common Stock otherwise issuable to the Optionholder as a result of the
exercise or acquisition of stock under the Option, provided, however, that no
shares of Common Stock are withheld with a value exceeding the minimum amount of
tax required to be withheld by law; or (iii) delivering to the Company owned and
unencumbered shares of the Common Stock.

11.  Adjustments upon Changes in Stock.

     (a)  Capitalization Adjustments. If any change is made in the stock subject
to the Plan, or subject to any Option, without the receipt of consideration by
the Company (through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of

                                      8.
<PAGE>

consideration by the Company), the Plan will be appropriately adjusted in the
class(es) and maximum number of securities subject both to the Plan pursuant to
subsection 4(a) and to the nondiscretionary Options specified in Section 5, and
the outstanding Options will be appropriately adjusted in the class(es) and
number of securities and price per share of stock subject to such outstanding
Options. The Board shall make such adjustments, and its determination shall be
final, binding and conclusive. (The conversion of any convertible securities of
the Company shall not be treated as a transaction "without receipt of
consideration" by the Company.)

     (b)  Change in Control--Dissolution or Liquidation.  In the event of a
dissolution or liquidation of the Company, then all outstanding Options shall
terminate immediately prior to such event.

     (c)  Change in Control--Asset Sale, Merger, Consolidation or Reverse
Merger. In the event of (i) a sale, lease or other disposition of all or
substantially all of the assets of the Company, (ii) a merger or consolidation
in which the Company is not the surviving corporation or (iii) a reverse merger
in which the Company is the surviving corporation but the shares of Common Stock
outstanding immediately preceding the merger are converted by virtue of the
merger into other property, whether in the form of securities, cash or
otherwise, then any surviving corporation or acquiring corporation shall assume
any Options outstanding under the Plan or shall substitute similar Options
(including an option to acquire the same consideration paid to the stockholders
in the transaction described in this subsection 11(c) for those outstanding
under the Plan). In the event any surviving corporation or acquiring corporation
refuses to assume such Options or to substitute similar Options for those
outstanding under the Plan, then with respect to Options held by Optionholders
whose Continuous Service has not terminated, the vesting of such Options (and
the time during which such Options may be exercised) shall be accelerated in
full, and the Options shall terminate if not exercised at or prior to such
event. With respect to any other Options outstanding under the Plan, such
Options shall terminate if not exercised prior to such event.

     (d)  Change in Control--Securities Acquisition. In the event of an
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Exchange Act, or any comparable successor provisions (excluding
any employee benefit plan, or related trust, sponsored or maintained by the
Company or an Affiliate) of the beneficial ownership (within the meaning of Rule
13d-3 promulgated under the Exchange Act, or comparable successor rule) of
securities of the Company representing at least fifty percent (50%) of the
combined voting power entitled to vote in the election of Directors and provided
that such acquisition is not a result of, and does not constitute a transaction
described in, subsection 11(c) hereof, then with respect to Options held by
Optionholders whose Continuous Service has not terminated, the vesting of such
Options (and, if applicable, the time during which such Options may be
exercised) shall be accelerated in full.

     (e)  Change in Control--Change in Incumbent Board.  In the event that the
individuals who, as of the date of the adoption of this Plan, are members of the
Board (the "Incumbent Board"), cease for any reason to constitute at least fifty
percent (50%) of the Board

                                      9.
<PAGE>

and provided that such change in the Incumbent Board does not occur solely as a
result of and/or following a transaction described in subsection 11(c) hereof,
then with respect to Options held by persons whose Continuous Service has not
terminated, the vesting of such Options (and, if applicable, the time during
which such Options may be exercised) shall be accelerated in full. If the
election, or nomination for election, by the Company's stockholders of any new
Director was approved by a vote of at least fifty percent (50%) of the Incumbent
Board, such new Director shall be considered as a member of the Incumbent Board.

12.  Amendment of the Plan and Options.

     (a)  Amendment of Plan.  The Board at any time, and from time to time, may
amend the Plan.  However, except as provided in Section 11 relating to
adjustments upon changes in stock, no amendment shall be effective unless
approved by the stockholders of the Company to the extent stockholder approval
is necessary to satisfy the requirements of Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

     (b)  Stockholder Approval. The Board may, in its sole discretion, submit
any other amendment to the Plan for stockholder approval.

     (c)  No Impairment of Rights. Rights under any Option granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the Optionholder and (ii) the
Optionholder consents in writing.

     (d)  Amendment of Options. The Board at any time, and from time to time,
may amend the terms of any one or more Options; provided, however, that the
rights under any Option shall not be impaired by any such amendment unless (i)
the Company requests the consent of the Optionholder and (ii) the Optionholder
consents in writing.

13.  Termination or Suspension of the Plan.

     (a)  Plan Term. The Board may suspend or terminate the Plan at any time.
Unless sooner terminated, the Plan shall terminate on the day before the tenth
(10/th/) anniversary of the date the Plan is adopted by the Board or approved by
the stockholders of the Company, whichever is earlier. No Options may be granted
under the Plan while the Plan is suspended or after it is terminated.

     (b)  No Impairment of Rights. Suspension or termination of the Plan shall
not impair rights and obligations under any Option granted while the Plan is in
effect except with the written consent of the Optionholder.

14.  Effective Date of Plan.

     The Plan shall become effective on the IPO Date, but no Option shall be
exercised unless and until the Plan has been approved by the stockholders of the
Company, which approval shall be within twelve (12) months before or after the
date the Plan is adopted by the Board.

                                      10.

15.  Choice of Law.

     All questions concerning the construction, validity and interpretation of
this Plan shall be governed by the law of the State of Delaware, without regard
to such state's conflict of laws rules.
