                             Terms and Conditions

UNLESS OTHERWISE STATED, ALL CAPITALIZED TERMS USED HEREIN SHALL HAVE THE
MEANING ASCRIBED TO THEM IN THE AGREEMENT.

a)  Program Incentives/Penalties.
    ----------------------------

    (1)  Implementation Incentives: EarthWatch and Kodak shall aggressively
         -------------------------
         identify design and implementation techniques which can control and/or
         reduce the costs and schedules of the program. Where changes to
         contract requirements are identified by Kodak and lead to a reduction
         in the definitized price of the contract, the parties shall share in
         such reductions on a 50/50 percentage basis.

    (2)  Schedule Penalties: The scheduled delivery date for each Sensor
         ------------------
         Subsystem is defined in Exhibit 4 to this Agreement. The price paid to
         Kodak shall be reduced by a penalty of $ 10,000 per day for each day
         from day one to day sixty that delivery is delayed beyond the
         scheduled delivery date. The price paid to Kodak shall be reduced by a
         penalty of $5,000 per day for each day from day sixty-one to day one
         hundred twenty that delivery is delayed beyond the scheduled delivery
         date. These late delivery penalties shall also apply to the optional
         second unit. For the purposes of calculating any resulting penalty,
         delivery shall be considered the date of shipment from Kodak.

b)  Acceptance of Deliverables.
    --------------------------

    (1)  Acceptance. Shipment approval shall occur at Kodak's facility
         ----------
         following satisfactory completion of the Flight Model Pre-Ship Review
         as specified in the Statement of Work. Acceptance shall occur after
         receipt and inspection at the Space Segment Integrating Contractor's
         facility or other designated facility within the Continental U.S.
         Acceptance will be assumed if inspection is not performed within one
         (1) day of receipt.

    (2)  Risk of Loss of Deliverables. Title and risk of loss to the
         ----------------------------
         Deliverables shall remain with Kodak and shall pass to EarthWatch when
         EarthWatch accepts the Deliverables.

c)  Mutual Confidentiality: Disclosure of confidential and proprietary
    ----------------------
    information shall be treated in accordance with the terms of the
    Confidentiality Agreement between Kodak and EarthWatch, dated 24 June 1996,
    included herein as Exhibit 5.

d)   Use of Facilities: Kodak and Kodak's employees, contractors and agents who
     -----------------
     are performing Services shall have access to appropriate EarthWatch and
     Space Segment Integrating Contractor sites as needed to perform their
     tasks. Kodak shall be responsible for Kodak's and associated personnel
     observing site rules and regulations, including, but not limited to, safety
     regulations, security requirements and rules relating to working in harmony
     with others at the site.

e)   Payment Terms:
     -------------

    1)    Responsibility for Expenses: EarthWatch shall have no obligation to
          ---------------------------
          Kodak for any charges unless the charges are expressly authorized in
          the Statement of Work or this Agreement. Kodak shall not incur any
          expenses on behalf of EarthWatch unless specifically authorized to do
          so in the applicable Statement of Work or this Agreement. Any expenses
          that are otherwise reimbursable to Kodak that are not listed in the
          Statement of Work or this Agreement are subject to prior review and
          approval by EarthWatch.

    2)    Invoices: Kodak shall issue invoices in accordance with the milestone
          --------
          schedule set forth in Exhibit 4. Invoices shall describe the
          milestones completed, the amounts due for the milestones, and
          applicable taxes, if any. The invoices shall be sent via overnight
          mail.

    3)    Payments and Billing Disputes:  Kodak shall be paid by EarthWatch
          -----------------------------
          upon successful completion of each program milestone and submission of
          a corresponding invoice. These amounts must be received by Kodak
          within 30 calendar days of the invoice date. All payments made to
          Kodak from EarthWatch shall be in U.S. dollars. EarthWatch shall pay a
          penalty of one percent (1.00%) of the full invoice amount for each
          month, or any portion of a month, that a payment is past due until the
          past due amount is paid by EarthWatch. Late payment charges will be
          billed to EarthWatch on a separate invoice. Kodak shall be solely
          responsible for payment to its vendors and suppliers for all sums
          properly due such parties.

          In the event that EarthWatch does not agree with the completion of a
          milestone invoiced by Kodak, EarthWatch shall so notify Kodak in
          writing within 5 business days of receipt of the invoice. If it is
          determined that Kodak has not completed the milestone as specified in
          Exhibit 4, the invoice date shall be delayed until such time as the
          milestone is completed. If it is determined that Kodak had properly
          completed the milestone as of the original invoice date, then payment
          shall be due within 30 calendar days of the original invoice date and
          all applicable late payment penalties shall apply.

      EarthWatch shall send payments to the following address and shall include
      Kodak's invoice number on all payments:

           EASTMAN KODAK COMPANY
           P.O. Box 100813
           Atlanta, GA 30384

      Payments may also be made by wire transfer to:

           CITIBANK N.A.
           New York, New York
           Routing/Transfer No. 0210-0008-9
           Account No. 40550939 (Domestic)

      Include the following information:

           EarthWatch Incorporated, Longmont, CO
           Customer No. 0565143
           Invoice No: To be completed with each transfer
           Amount Paid: To be completed with each transfer

      In the event Kodak fails to complete any milestone on or before the
      planned completion date, EarthWatch shall not be required to pay the
      amount specified for the milestone until it is completed.

      In the event that the planned completion of a milestone is delayed because
      of contractual direction from EarthWatch, both parties agree that the
      milestone description will be changed to a new mutually agreed to payment
      milestone description, consistent with the original planned date of
      completion.

  4)  Taxes:
      -----

      Sales and Use Taxes: All taxes and similar assessments, levies and
      -------------------
      government imposed obligations arising with respect to Deliverables
      (except for taxes on Kodak's income) shall be the obligation of and be
      paid by EarthWatch.

      All payments for sales and use taxes shall be collected from EarthWatch by
      Kodak and remitted to the proper taxing authority, in the legally defined
      timeframe determined by each taxing authority.

      Assuming shipment of any deliverable into the State of Colorado, the
      Non-Recurring Engineering Design Charges identified in Exhibit 4 to this
      Agreement, will be exempt from Sales and Use Tax. Kodak will include these
      charges as a separate line item(s) on their invoices.

          The final products (Sensor Subsystems) are tangible personal property
          and subject to Colorado Sales and Use Tax unless a Colorado Resale
          Exemption Certificate is provided to Kodak by EarthWatch. EarthWatch
          agrees to reimburse Kodak for tax, interest, and any penalty assessed
          by the State of Colorado arising from a determination by the State of
          Colorado that the Resale Certificate is invalid.

          Billing will occur with milestone payments up to the value of the Non-
          Recurring Engineering Design Charges which will be exempt from sales
          and use tax, with subsequent milestone payments reflecting the final
          products (Sensor Subsystems) which will be taxed, unless a Resale
          Certificate is obtained.

          Should shipment of any deliverable be into a state other than
          Colorado, Kodak shall coordinate with EarthWatch in determining and
          collecting the proper taxes.

          Licenses, Gross Receipts, Business and Occupation Taxes: Each company
          -------------------------------------------------------
          will be responsible for its own licenses, gross receipts, and business
          and occupation taxes.

          Property Taxes: Each company will be responsible for property taxes
          --------------
          due on property owned by the respective company.

          Other Taxes: Each company will be responsible for its own corporate
          -----------
          income, franchise taxes, etc. based upon income and/or net worth.

 f)    Termination:
       -----------

       1) Termination for Default by Kodak: EarthWatch may terminate for default
          --------------------------------
          by Kodak if:

          (a) Kodak fails to make satisfactory delivery on a Deliverable within
              150 days of its scheduled delivery date,

          (b) Kodak's failure to make progress gives EarthWatch reasonable
              grounds to conclude that Kodak will fail to deliver a Deliverable
              within 150 days of the scheduled date, or

          (c) Kodak breaches any other material provision of the Agreement, and
              does not take adequate steps to cure such breach within 30 days
              after receipt of written notice from EarthWatch specifying such
              breach.

          Within 24 hours of a termination notice under this section, Kodak
          shall cease incurring any additional costs with respect to the
          Services or Deliverables. EarthWatch shall pay Kodak the lesser of the
          termination liability specified in Exhibit 4 or Kodak's actual
          incurred costs as verified by audit, plus reasonable termination costs
          from the effective date of termination.

      Kodak shall provide to EarthWatch, in an "as is" condition, all
      Deliverables including flight hardware, ground support equipment,
      software, and data as defined in the Statement of Work, either completed
      or in process as of the date of termination. Kodak shall assign all of its
      rights and obligations under any uncompleted Subcontracts to EarthWatch
      upon the written request of EarthWatch at the time of notification of
      termination. Assignment of any subcontract shall not convey any of Kodak's
      rights to intellectual property and Kodak property in the possession of
      the subcontractor which is not a deliverable under the subcontract.

      EarthWatch, as an alternative to receipt of Deliverables, may require
      Kodak to refund all payments under this Agreement made by EarthWatch to
      Kodak in addition to its other remedies under this Agreement or at law or
      equity.

2)    Termination for Default by EarthWatch: Kodak may terminate for Default by
      -------------------------------------
      EarthWatch if:

      (a)  EarthWatch fails to make timely payments as required herein and does
           not make such required payment within 30 days after notice from Kodak
           that such payment is overdue,

      (b)  EarthWatch declares bankruptcy or enters receivership, or admits in
           writing its inability to pay its debts as such debts become due, or

      (c)  EarthWatch breaches any other material provision of this Agreement,
           and does not take adequate steps to cure such breach within 30 days
           after receipt of written notice from Kodak specifying such breach.

      Within 24 hours of a termination notice under this section, Kodak shall
      cease incurring any additional costs with respect to the Services or
      Deliverables. EarthWatch shall be required to pay Kodak the lesser of the
      termination liability specified in Exhibit 4 or Kodak's actual incurred
      costs as verified by audit, reasonable termination costs from the
      effective date of termination, a reasonable profit on work performed, and
      reasonable anticipated profit on any terminated efforts.

      In the event of termination of this Agreement under this section, and upon
      payment of the termination amount as specified, Kodak shall provide to
      EarthWatch, in an "as is" condition, all Deliverables including flight
      hardware, ground support equipment, software, and data as defined in the
      Statement of Work, either completed or in process as of the date of
      termination. In the event of default by EarthWatch, nothing in this
      section shall preclude Kodak from pursuing its other remedies at law or
      equity.

3)    Termination for Convenience by EarthWatch: EarthWatch may terminate the
      -----------------------------------------
      Agreement at any time for convenience on 30 days written notice to Kodak

          provided EarthWatch is not in default of any material provision of
          this agreement prior to the date of termination. Within 24 hours of
          its receipt of a termination notice under this section, Kodak shall
          cease incurring any additional costs with respect to the Services or
          Deliverables, unless EarthWatch's termination notice states otherwise.
          In the event of such termination, EarthWatch will pay Kodak the lesser
          of the termination liability specified in Exhibit 4 or Kodak's actual
          incurred costs as verified by audit, reasonable termination costs from
          the effective date of termination, a reasonable profit on work
          performed, and reasonable anticipated profit on terminated efforts.

          provide to EarthWatch, in an "as is" condition, all Deliverables
          including flight hardware, ground support equipment, software, and
          data as defined in the Statement of Work, either completed or in
          process as of the date of termination.

    4)    Other Consequences of Termination. In addition, upon the expiration or
          ---------------------------------
          termination of this Agreement, Kodak and Kodak's personnel shall
          promptly return to EarthWatch or destroy, as EarthWatch directs, all
          papers, written materials, equipment and other information furnished
          to Kodak or Kodak's personnel by EarthWatch in connection with or as a
          result of its performance under this Agreement.

g)  Changes: The representatives identified in Section (o)(3) shall be
    -------
    authorized to request, negotiate, and authorize changes within the general
    scope of this Agreement including any one or more of the following:

          1.  Drawings, designs, or specifications of any Deliverables to be

    Contract, an equitable adjustment in (i) the Contract price, the delivery
    schedule, or both; and (ii) other affected terms of the Contract, and shall
    be incorporated into the Contract. Such adjustments shall be negotiated in
    good faith between Kodak and EarthWatch.

    Either party must assert its right to an adjustment under this clause within
    ten (10) days from the date of receipt of a written requested change from
    the other party. In the event that an adjustment is warranted Kodak shall
    submit a priced change proposal within 45 days. Not-To-Exceed change
    proposals may be used to accelerate this process.

    If Kodak's proposal includes the cost of property made obsolete or excess by
    the change, EarthWatch shall have the right to prescribe the manner of the
    disposition of the property.

    No services for which an additional cost or fee will be charged by Kodak
    shall be furnished without prior written authorization of EarthWatch's
    Authorized Representative. No change will be binding upon Kodak unless
    issued in writing by EarthWatch's Authorized Representative.

    Failure to agree to any adjustment shall be a dispute. However, nothing in
    this clause shall excuse Kodak from proceeding with the Contract as changed.

     extension is equal to or greater than one hundred eighty (180) days.

l)   Product Warranty Provisions:
     ---------------------------

      1)   Warranty on Deliverables and Services. Kodak hereby represents and
           -------------------------------------
           warrants that the Deliverables shall be free from defect in material
           and workmanship and the completed Sensor Subsystems will conform to
           and perform in accordance with the Performance Specifications and
           Interface Specifications for a period of twelve (12) months or until
           launch, whichever occurs first, after EarthWatch's acceptance of such
           Deliverables (the "Warranty Period"). EarthWatch shall notify Kodak
           and allow Kodak to be present during installation, integration, and
           or testing of the Deliverables to assure proper handling and use
           under the warranty. Any action performed by Kodak under the terms of
           this Warranty clause will not extend the warranty period.

      2)   Breach of Warranty. EarthWatch shall give written notice to Kodak of
           ------------------
           any breach of warranty occurring within the Warranty Period. Such
           notice shall include sufficient information to determine the part
           number, serial number, the nature and the circumstances of the
           alleged defect. Kodak shall promptly investigate the breach and
           advise EarthWatch of planned corrective action. In the event of a
           breach of the warranty, and as sole remedy, Kodak will, at its
           option, repair or replace, at the point of manufacture, or on site,
           any defective Deliverables at Kodak's expense. Defects identified in
           the first unit, including those identified on orbit, shall be
           repaired in any optional units covered under this Agreement. Kodak
           shall also correct any Technical Data pertinent to defective
           equipment to the extent delineated herein above.

      3)   Limitations. This warranty shall not apply to any defects in
           -----------
           Deliverables caused by accident, misuse, unauthorized alteration,
           normal wear, or improper installation, maintenance and service. This
           is not a fix all failures warranty. This warranty does not cover
           reimbursement for expenses for labor in gaining access to, removal
           and installation of defective products. Kodak shall be responsible
           for repair or replacement at either the point of delivery or at
           Kodak's facilities. Transportation costs from other locations shall
           be EarthWatch's responsibility. THE FOREGOING WARRANTIES AND REMEDIES
           ARE EXCLUSIVE AND ARE IN LIEU OF ANY WARRANTY OF MERCHANTABILITY,

m)  Compliance with Laws: Kodak agrees that it will comply with all applicable
    --------------------
    federal, state and local laws, regulations and codes in effect as of the
    Effective Date, and throughout the duration of work under this Agreement.

n)  Indemnification:
    ---------------

    Kodak will defend at its expense any legal proceeding brought against
    EarthWatch, to the extent that it is based on a claim that the design or use
    of any Deliverables is a direct infringement of a copyright, of a
    proprietary or ownership right of a third party, or of a U.S. patent, and
    will pay all damages and costs awarded by a court of final appeal
    attributable to such claim, provided that EarthWatch: (i) provides Notice of
    the claim promptly to Kodak; (ii) gives Kodak sole control of the defense
    and settlement of same; (iii) provides to Kodak all available information,
    assistance and authority to defend; and (iv) has not compromised or settled
    such proceeding without Kodak's prior written consent.

    Should any Deliverables or any portion thereof become, or in Kodak's opinion
    be likely to become the subject of a claim of infringement, Kodak shall, as
    EarthWatch's sole and exclusive remedy, elect to: (i) obtain for EarthWatch
    the right to use such Deliverables; (ii) replace or modify the Deliverables
    so that they become non-infringing and still satisfy all other requirements
    of this Agreement.

    Kodak shall have no liability for any infringement or claim which results
    from (i) use of the Deliverables in combination with any non-Kodak provided
    equipment, software or data, if such infringement would have been avoided by
    use of the Deliverables without such equipment, software, or data; (ii)
    Kodak compliance with designs or specifications of EarthWatch that contain
    infringing information.

    THIS ARTICLE STATES THE ENTIRE LIABILITY OF KODAK WITH RESPECT TO
    INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS BY THE DELIVERABLES AND
    KODAK SHALL HAVE NO ADDITIONAL LIABILITY WITH RESPECT TO ANY ALLEGED OR
    PROVEN INFRINGEMENT.

                          CONFIDENTIALITY AGREEMENT

In Order to protect certain proprietary, confidential information, which may be
disclosed between the parties pursuant to contracts for the EarthWatch Quickbird
Sensor Subsystem, Eastman Kodak Company ("Kodak", "EarthWatch", and Ball
Aerospace & Technology Corporation ("Ball Aerospace") agree that:

1.  The "Effective Date" of this agreement is 20 January 1997.
                                              ---------------

2.  Information and data relative to the EarthWatch Quickbird Satellite System
                                         -------------------------------------
    will be exchanged between the parties for the purpose of execution of
    contracts from EarthWatch for the "EarthWatch Quickbird Satellite System."

3.  Each Party agrees to designate a representative, identified below, for
    administering the disclosure and/or receipt of confidential information
    hereunder:

     Michele A. Steffen        Neal Anderson            George Niquette
     ------------------        -------------            ---------------
        (Kodak)                (EarthWatch)             (Ball Aerospace)

4.  This Agreement covers only confidential information which is (a) within the
    scope of paragraph 2 above, and (b) disclosed during the active period of
    the EarthWatch "EarthWatch Quickbird Satellite System" contracts.

5.  A Recipient's obligations regarding confidential information received under
    this Agreement expires three years after the completion of the "EarthWatch
                           -----
    Quickbird Satellite System" contract. Any of the Parties may terminate its
    participation in this agreement upon thirty (30) days notice to the others.

6.  A Recipient shall protect the confidential information against unauthorized
    disclosure using the same degree of care, but no less than a reasonable
    degree of care, as the Recipient uses to protect its own confidential
    information of a like nature.

7.  A Recipient shall be obligated to protect only such confidential information
    disclosed under this Agreement as is: (a) disclosed in tangible form,
    electronic form, or encrypted electronic mail, clearly labeled as
    confidential at the time of disclosure, (b) disclosed initially in non-
    tangible form identified as confidential at the time of disclosure and,
    within thirty days following the initial disclosure, summarized and
    designated as confidential in a written memorandum delivered to the
    Recipient's representative named in paragraph 3 above.

8.  This Agreement imposes no obligation upon a Recipient with respect to any
    confidential information disclosed under this Agreement when: (a) was in the
    Recipient's possession before receipt from the Discloser, or (b) is or
    becomes a matter of public knowledge through no fault of the Recipient; or
    (c) is rightfully received by the Recipient from a third party without a
    duty of confidentiality; or (d) is disclosed by the Discloser to a third
    party without a duty of confidentiality on the third party; or (e) is
    independently developed by the Recipient; or (f) is disclosed under
    operation of law; or (g) is disclosed by Recipient with the Discloser's
    prior written approval.

9.  Each Discloser certifies that it has the right to make the disclosures under
    this Agreement, and all such disclosures are at the sole discretion of the
    Discloser.

10. No party acquires any intellectual property rights under this Agreement; no
    party has an obligation under this Agreement to purchase any service or item
    from an other party; or to deal exclusively with an other party in any
    field, and no party has an obligation under this Agreement to offer for sale
<PAGE>

    products using or incorporating the confidential information. The Discloser
    may, at its sole discretion, offer such products for sale and may modify
    them or discontinue sale at any time.

11. A Recipient shall adhere to the U.S. Export Administration Laws and
    Regulations, ITARS, Export Administration Act and shall not export or re-
    export any technical data or products received from the Discloser or the
    direct products of such technical data to any proscribed country listed in
    the U.S. Export Administration Regulations unless properly authorized by the
    U.S. Government. A Recipient shall first obtain the written consent of the
    Disclosing Party prior to submitting any request for authority to export any
    such technical data, and the recipient shall obtain any export license, if
    applicable.

12. The parties do not intend that any agency or partnership relationship be
    created between them by this Agreement.

13. All additions or modifications to this agreement must be made in writing and
    must be signed by all parties. This Agreement is made under and shall be
    construed according to the laws of the State of Colorado.

14. By signature of this agreement, the previous confidentiality agreement
    between EarthWatch and Kodak dated 24 June 1996 is superseded, the previous
    confidentiality agreement between Ball and Kodak (#354) dated 2 July 1996 is
    superseded, and the previous confidentiality agreement between Ball and
    EarthWatch dated 5 Feb. 1996 is superseded.

                             CONTRACT 1M.SSS.002.A

                                    for the
                     EARTHWATCH QUICKBIRD SENSOR SUBSYSTEM

This Amendment revises the Statement of Work, program schedule, Payment Schedule
and specified Contract Terms. Effective as of the notification provided to Kodak
on July 15, 1997 and confirmed in EarthWatch letter no. 9700070, dated 22 July
1997, Kodak is to perform at a reduced level of effort pending restructuring of
this Contract. Through the month of August 1997, Kodak shall perform to Addendum
1 to Statement of Work for the EarthWatch QuickBird Sensor Subsystem, Document
No. SE.lM.SSS.005.C. These activities shall be performed for a fixed price of
$400,000. An additional contract amendment will be required for performance
beyond August 31, 1997. EarthWatch intends to restructure the subject contract
and subsequently re-negotiate the Contract price and delivery schedule.

The following paragraph is added to Article 1:

ARTICLE 1: OVERALL SCOPE OF THE PROJECT
---------------------------------------

During the period July 15, 1997 through August 31, 1997, the scope of the
project shall be reduced as follows. Subject to the Terms and Conditions listed
in Exhibit 1, Kodak shall provide the necessary resources to perform the
Services specified only in Addendum 1 (dated August 4, 1997) to the Statement of
Work for the QuickBird Sensor Subsystem, Document SE. 1M.SSS.005.C, dated June
18, 1997, attached hereto as Exhibit 2A (the "August Statement of Work"). All
work shall be performed to meet the performance and verification requirements
specified in the Statement of Work, the Performance Specification for the
QuickBird (QB) Spacecraft Sensor Subsystem, Document SE.lM.SSS.004.B, dated June
18, 1997 attached hereto as Exhibit 3 (the "Performance Specifications") and
satisfy the interface requirements in the Sensor Subsystem Interface Control
Document for the QuickBird Spacecraft, Document SP0031A-018E, dated June 18,
1997 (the "Interface Specifications").

Article 2 is replaced in its entirety with the following.

ARTICLE 2: PRICE AND PAYMENT
----------------------------

The total prices for the two units, exclusive of any sales or value added tax,
payable by EarthWatch to Kodak shall be as specified in Exhibit 4 as amended
August 4, 1997. The payment schedule shall be based upon the accomplishment of
milestones in the program as identified in Exhibit 4. The payment schedule and
termination liability schedule shall be as specified in Exhibit 4. With this
amendment, EarthWatch has instituted a change to the requirements and the terms
of this agreement. Subject to the contract being restructured, the total price,
delivery, payment schedule, and termination liability schedule shall be re-
negotiated.

                                                          Contract 1M.SSS.0002.A
                                                                        08/07/97

Exhibit 1 paragraph a) (2) is modified to immediately suspend the schedule
penalties.

Exhibit 1 paragraph e) 3) is modified to require payment of the 8/15/97 payment
milestone ($400,000) on or before August 18, 1997.

Exhibit 1 paragraph f) 5) is added to provide Kodak the right to terminate for
convenience in the event that an amendment extending performance of the contract
is not executed by September 1, 1997.

Termination for Convenience by Kodak: If an amendment to this Contract,
------------------------------------
extending performance beyond August 31, 1997, is not executed by September 1,
1997, Kodak shall have the right to terminate the Contract for its convenience
provided that Kodak is not in default of any material provision of this contract
prior to the date of termination. Upon termination notification to EarthWatch,
Kodak shall cease incurring any additional costs with respect to the Services or
Deliverables. In the event of such termination, EarthWatch will pay Kodak the
lesser of the termination liability specified in Exhibit 4 or Kodak's actual
incurred costs as verified by audit, reasonable termination costs from the
effective date of termination, a reasonable profit on work performed, and
reasonable anticipated profit on terminated efforts.

In the event of termination of this Agreement under this section, and upon
payment of the termination amount as specified, Kodak shall provide to
EarthWatch, in an "as is" condition, all Deliverables including flight hardware,
ground support equipment, software, and data as defined in the Statement of
Work, either completed or in process as of the date of termination.

Exhibit 4 - Pricing/Payment/Termination Liability dated May 8, 1997 is deleted
and replaced in its entirety with Exhibit 4 - Pricing/Payment/Termination
Liability (Amended August 4, 1997). The delivery schedule and the associated
schedule penalties are also suspended.

All references to these documents shall be to these revisions.

                             CONTRACT 1M.SSS.002.A
                                    between
                   EARTHWATCH, INC. AND EASTMAN KODAK COMPANY
                                    for the
                     EARTHWATCH QUICKBIRD SENSOR SUBSYSTEM

This Amendment revises the Statement of Work, Payment Schedule and specified
Contract Terms. Kodak is to continue through the month of September 1997
performing at a reduced level of effort pending restructuring of this Contract.
During the month of September 1997, Kodak shall perform to Addendum Two to the
Statement of Work for the EarthWatch QuickBird Sensor Subsystem, Document No.
SE.lM.SSS.005.C. These activities shall be performed for a fixed price of
$250,000. A separate contract amendment will be required for performance beyond
September 30, 1997.

BY THIS AMENDMENT, THE FOLLOWING CHANGES TO THE CONTRACT ARE MADE:

The following paragraph is added to Article 1:

During the period September 01, 1997 through September 30, 1997, the scope of
the project shall be reduced as follows. Subject to the Terms and Conditions
listed in Exhibit 1, Kodak shall provide the necessary resources to perform the
Services specified only in Addendum Two (dated August 26, 1997) to the Statement
of Work for the QuickBird Sensor Subsystem, Document SE.lM.SSS.005.C, (dated
June 18, 1997) attached hereto as Exhibit 2B (the "September Statement of
Work"). All work shall be performed to meet the performance and verification
requirements specified in the Statement of Work, the Performance Specification
for the QuickBird (QB) Spacecraft Sensor Subsystem, Document SE.lM.SSS.004.B,
dated June 18, 1997 attached hereto as Exhibit 3 (the "Performance
Specifications") and satisfy the interface requirements in the Sensor Subsystem
Interface Control Document for the QuickBird Spacecraft, Document SP0031A-018E,
dated June 18, 1997 (the "Interface Specifications").

Article 2 is modified to delete the reference to Exhibit 4 as amended August 4,
1997 and replace it with a reference to Exhibit 4 as amended August 26, 1997.

Exhibit 1 paragraph e) 3) is modified to require payment of the 9/l/97 payment
milestone ($250,000) on or before September 05, 1997.

Exhibit 1 paragraph f) 5) is replaced in its entirety with the following:

                                                          Contract 1M.SSS.0002.A
                                                                        08/29/97

Termination for Convenience by Kodak: If an amendment to this Contract,
------------------------------------
extending performance beyond September 30, 1997, is not executed by October 01,
1997, Kodak shall have the right to terminate the Contract for its convenience
provided that Kodak is not in default of any material provision of this contract
prior to the date of termination. Upon temination notification to EarthWatch,
Kodak shall cease incurring any additional costs with respect to the Services or
Deliverables. In the event of such termination, EarthWatch will pay Kodak the
lesser of the termination liability specified in Exhibit 4 or Kodak's actual
incurred costs as verified by audit, reasonable termination costs from the
effective date of termination, a reasonable profit on work performed, and
reasonable anticipated profit on terminated efforts.

In the event of termination of this Agreement under this section, and upon
payment of the termination amount as specified, Kodak shall provide to
EarthWatch, in an "as is" condition, all Deliverables including flight hardware,
ground support equipment, software, and data as defined in the Statement of
Work, either completed or in process as of the date of temination.

Exhibit 4 - Pricing/Payment/Termination Liability (Amended August 04, 1997) is
deleted and replaced in its entirety with Exhibit 4-Pricing/Payment/Termination
Liability (Amended August 26,1997).

All references to these documents shall be to these revisions.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed
by their respective duly authorized representatives.

                                                          Contract 1M.SSS.0002.A
                                                                        03/17/98

                      Amendment 8 Revisions to Exhibit 1
                                      to
            Agreement for the EarthWatch QuickBird Sensor Subsystem
                                March 13, 1998

Delete paragraph a)2) Schedule Penalties. And insert the following
                      ------------------

a)2) Liquidated Damages: Since it is impossible to quantify the damages that
     ------------------
EarthWatch will incur as the result of any delivery made later than the schedule
in Exhibit 4, and as time is of the essence in the performance of this contract,
the parties have agreed upon liquidated damages to be assessed in such an event.
The application of liquidated damages to FM1 shall be based on a scheduled
delivery date of January 15, 1999 as defined in Exhibit 4 to this Agreement.
There is a ten day grace period which means that liquidated damages will not
accrue until January 26, 1999. Beginning on January 26, 1999, the price paid to
Kodak shall be reduced by $5,000 per day for each day through sixty days from
the end of the grace period that delivery is delayed beyond the end of the grace
period date. For the purposes of calculating any resulting liquidated damages,
delivery shall be considered the date of shipment from Kodak. This clause
constitutes in its entirety the damages redeemable under the contract for late
delivery for the period stated herein. Liquidated damages for late delivery do
not apply to FM2.

a)3) Schedule Incentive This contract includes a schedule incentive for the
     ------------------
early completion and delivery of FM 1. If FM1 is delivered earlier than the
scheduled delivery in Exhibit 4, KODAK will earn an incentive fee of $10,000 per
day for each day in advance of the scheduled delivery in Exhibit 4. The maximum
schedule incentive that can be earned under this clause is $300,000. The
schedule incentive is in addition to the prices due for the milestones. For the
purposes of this clause, delivery shall be considered the date of shipment from
KODAK. Any earned schedule incentive can be invoiced following delivery of FM1.
Schedule incentives do not apply to FM2.

Delete Paragraph e) 3) Payment and Billing Disputes and replace with the
                       ----------------------------
following.

e)3) Payments and Billing Disputes: Kodak shall be paid by EarthWatch upon
     -----------------------------
successful completion of a payment milestone according to the completion
criteria and submission of a corresponding invoice. This includes milestones
completed in advance of the schedule in Exhibit 4. These amounts must be
received by Kodak within 30 calendar days of the invoice date. All payments made
to Kodak from EarthWatch shall be in U. S. dollars. EarthWatch shall pay a
penalty of one percent (1.00%) of the full invoice amount for each month, or any
portion of a month, that a payment is past due until the past due amount is paid
by EarthWatch. Late payment charges will be billed to EarthWatch on a separate
invoice. Kodak shall be solely responsible for payment to its vendors and
suppliers for all sums properly due such parties.
     In the event that EarthWatch does not agree with the completion of a
milestone invoiced by Kodak, EarthWatch shall so notify Kodak in writing within
5 business days of receipt of the invoice. If it is determined that Kodak has
not completed the milestone as specified in Exhibit 4, the invoice date shall be
delayed until such time as the milestone is completed. If it is determined that
Kodak had properly completed the milestone as of the original invoice date, then
payment shall be due within 30 calendar days of the original invoice date and
all applicable late payment penalties shall apply.

          Payments may also be made by wire transfer to:
               CITIBANK N.A.

               Invoice No: To be completed with each transfer
               Amount Paid: To be completed with each transfer

     In the event Kodak fails to complete any milestone on or before the planned
completion date, EarthWatch shall not be required to pay the amount specified
for the milestone until it is completed.

     In the event that the planned completion of a milestone is delayed because
of contractual direction from EarthWatch, both parties agree that the milestone
description will be changed to a new mutually agreed to payment milestone
description, consistent with the original planned date of completion.

                     EARTHWATCH QUICKBIRD SENSOR SUBSYSTEM

This Amendment is issued to incorporate a change to support work out of scope to
the contract.

This amendment incorporates changes to the following documents:

Paragraph 4.3 Small Changes Management

BY THIS AMENDMENT, THE FOLLOWING CHANGES TO THE CONTRACT ARE MADE:

4.3  Small Changes Management
     -------------------------

     EarthWatch shall set-up and maintain a small changes reserve fund. The
     purpose of this small changes reserve fund is to enable the rapid approval
     of small efforts that are determined to be beyond the scope of the
     negotiated contract. The EarthWatch and Kodak Project Managers shall have
     the authority to identify and negotiate small changes in a timely manner.
     Changes under $25K may be negotiated verbally, but must be authorized in
     writing by the EarthWatch Project Manager or Contracts Manager. For changes
     over $25 K Kodak shall provide a brief description of the out-of-scope
     effort and a mini-proposal detailing the cost of the effort. These small
     changes shall not exceed $100k without a formal change to the Agreement.
     All authorized small changes shall be formally incorporated into the
     Agreement within 90 days.

     Two types of changes are possible: (1) fixed price and (2) cost
     reimbursable. Fixed price changes are those that can be adequately defined
     in advance and shall proceed as identified above. Cost plus changes shall
     be used where definition is not sufficient for a fixed price effort. For
     these changes, Earthwatch shall authorize, in writing, a funding limit for
     a particular change. Kodak shall accrue costs against this change per the
     following labor rate structure:

                      Grade          Hourly Rate
                     Engineer         @$146/hr.
                     Technician       @$112/hr
                     Mfg. Engineer    @$215/hr
                     Assembler        @$120/hr

                         Actual ODC costs

                                                                 Amendment 13 to
                                                          Contract 1M.SSS.0002.A

     These rates are those used by Kodak in their US government programs and
     will be updated on a yearly basis. EarthWatch is not obligated for costs
     incurred in excess of the funding limit. Kodak is not obligated to incur
     costs in excess of the funding limit.

     Individual small changes shall not exceed 100K without a formal change to
     the Agreement. Small changes may be invoiced on a monthly basis in
     accordance with the payment terms of the contract.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed
by their respective duly authorized representatives.
