                                                                    ------------
                               February 26, 1999

                  Strategic Supplier Agreement By And Between
                             ITT Industries, Inc.
                    1919 West Cook Road, Ft. Wayne, Indiana

                                      And
                            EarthWatch Incorporated
                 1900 Pike Road, Longmont, Colorado USA 80501


This Strategic Supplier Agreement ("Agreement") is entered into by and between
ITT Industries, Inc. ("ITT"), an Indiana corporation, with a place of business
at 1919 West Cook Road, Fort Wayne, IN 46818 and EarthWatch Incorporated
("EarthWatch"), a Delaware corporation, with its principal place of business at
1900 Pike Road, Longmont, Colorado 80501.

WHEREAS, ITT and EarthWatch have entered into a separate agreement,  pursuant to
which ITT has committed to invest certain funds in EarthWatch as detailed in the
Investment Agreement to be signed in the near future; and

WHEREAS ITT possesses capabilities and expertise in the design and production of
custom designed and manufactured electro-optical Earth imaging spacecraft-borne
sensors; and

WHEREAS EarthWatch may have certain needs to acquire such sensors over the next
ten years;

NOW, THEREFORE, in consideration of the mutual covenants for ITT's investment
and other commitments, contained herein, the parties have agreed as follows:

1.   Definitions: For the purposes of this Agreement, the following terms shall
     have the respective meanings indicated below.

     1.1.  Best Value: The assessment by EarthWatch that a bona fide Solicited
           ----------
           Proposal in response to an EarthWatch RFP for a Sensor is in
           compliance in all material respects with such RFP and provides
           EarthWatch with an overall graded value representing Best Value as
           assessed reasonably and in good faith by EarthWatch. The assessment
           may include, but need not be limited to, cost, project schedule,
           practicality and feasibility of technical design, life cycle costs,
           reliability, estimated life, state of the art for Sensors, the use of
           specified subcontractors, and contract terms and conditions. Best
           Value, however, does not necessarily mean the lowest priced proposal.
           A Solicited Proposal submitted by ITT that satisfies the RFP's
           technical requirements (including schedule) and falls within or below
           EarthWatch's internal "should cost" range for the Sensor shall be
           considered to be Best Value.

                                       1
<PAGE>

     1.2.  Parties: EarthWatch and ITT.
           --------

     1.3.  Procurement of a Sensor: The purchase of a Sensor, either newly
           ------------------------
           manufactured or already existing, in response to an RFP, which
           ultimately results in title to the Sensor being transferred to
           EarthWatch or a wholly owned subsidiary of EarthWatch.

     1.4.  Request for Proposal (RFP): A written request by EarthWatch for
           --------------------------
           delivery of one or more Sensor(s). The RFP shall identify
           requirements for the Sensor based on EarthWatch's statement of work,
           shall specify a required delivery date, and shall state the terms and
           conditions associated with the procurement. The RFP shall include a
           Statement of Work that encompasses design (if required), manufacture,
           and delivery of the Sensor(s). The final content of an RFP, including
           Statement of Work, attachments, and the "should cost" analysis shall
           be the sole responsibility of EarthWatch.

     1.5.  Sensor: An electro-optical device that images the Earth from a
           ------
           spacecraft, encompassing all subsystems and components necessary for
           conversion of photons into digital electronic output for delivery to
           the spacecraft bus's wideband data system including optics, baffles,
           focal plane(s), sensor electronics, unique power supplies,
           calibration sources, optical covers, and built-in sensor thermal
           management systems, as well as any other subsystems or ancillary
           support equipment customarily provided with the type of sensor being
           procured. This definition of Sensor is intended to apply to what are
           normally considered "payload" instruments, and to exclude ancillary
           sensors normally part of a satellite bus, such as those used for
           attitude control.

     1.6.  Solicited Proposal: A proposal received in response to an EarthWatch
           ------------------
           Request for Proposal.

2.   Exclusive Provider of Sensors

     2.1.  EarthWatch agrees that ITT shall be the exclusive provider and Sensor
           systems integration prime contractor to EarthWatch of Sensors when
           EarthWatch procures a Sensor to fly on either a spacecraft procured
           by EarthWatch or to fly on a spacecraft owned or operated by another
           party. ITT in turn agrees to provide Sensor systems integration and
           other related services, and Solicited Proposals meeting EarthWatch's
           requirements, including that ITT provide Best Value in its proposals
           to provide Sensors to EarthWatch.

     2.2.  EarthWatch and ITT will cooperatively work to develop the concepts
           for the Sensors. ITT will be involved in all material aspects of the
           concept development and/or definition for the Sensors, including
           without limitation the "should cost" analysis for the Sensors, and in
           the development of all material elements for the resulting RFP. This
           includes insight and visibility into potential Sensor subsystem
           vendor identification by EarthWatch or ITT. As part of the concept
           development activity, EarthWatch will contract with ITT to cover cost
           items

                                       2
<PAGE>

           incurred during the concept development that ITT would not normally
           be incurring as part of ITT's own independent R&D, B&P, or other non-
           EarthWatch ongoing business. Notwithstanding the foregoing,
           EarthWatch shall have final control of the contents of any RFP
           resulting from this process. The RFPs and RFP exhibit or attachment
           documents, including the "should cost" analysis, that result from
           concept development process will be considered EarthWatch proprietary
           and confidential material for the purposes of Section 6.2, except to
           the extent specifically agreed upon by the parties; provided however,
           that this RFP information will be available to ITT and ITT's
           potential suppliers and subcontractors.

     2.3.  After completion of concept definition and requirements
           specification, when EarthWatch procures a Sensor, it will issue an
           RFP to ITT. The RFP will specify a reasonable time limit for the
           submission of Solicited Proposals; this time limit will normally be
           thirty (30) to forty-five (45) days, but may be extended by agreement
           of EarthWatch.

     2.4.  Within the response time identified in the RFP, or as extended by
           mutual agreement, ITT will respond with a proposal for delivery of
           the Sensor.

     2.5.  Should ITT furnish a Solicited Proposal that fails to satisfy the
           definition of Best Value, EarthWatch, after the process in Section 4
           is completed, if elected by ITT, shall have the right to direct that
           a subcontract(s) be entered into with another supplier(s) to procure
           Sensor subsystem(s), which subsystem(s) would then be integrated into
           the Sensor under ITT's Sensor systems integration prime contract.

     2.6.  Upon receipt of a Best Value proposal, EarthWatch and ITT shall enter
           into good faith negotiations to allow the issuance of a contract.

3.   Determination of Best Value - EarthWatch may, in good faith, use one or
     more fair, reasonable and objective methods appropriate to the particular
     procurement to support a determination of Best Value. Possible methods
     include:

     3.1.  Following submission of a Solicited Proposal by ITT, EarthWatch may
           require ITT to provide back-up data to a Solicited Proposal including
           cost data and subcontract data.

     3.2.  During concept development, the Parties may discuss with potential
           Sensor subsystem suppliers alternative technologies that may improve
           performance or lower costs. The results of these discussions will be
           shared with the other Party to allow ITT to enhance the value to be
           delivered to EarthWatch and facilitate the determination of Best
           Value by EarthWatch. In order to be in a position to verify the Best
           Value of ITT's Solicited Proposal, EarthWatch may, upon release of
           the RFP for the Sensor, solicit non-binding proposals from
           alternative Sensor subsystem suppliers with notification to ITT.
           Alternative proposals for the Sensor, however, may not be solicited.

4.   Remedy for Non-Best Value Proposals

                                       3
<PAGE>

     4.1.  Should EarthWatch reasonably and in good faith determine that the ITT
           Solicited Proposal does not offer Best Value, EarthWatch shall so
           inform ITT in writing within forty-five (45) days of receipt of the
           Solicited Proposal. Any determination by EarthWatch that the ITT
           Solicited Proposal does not represent or does not constitute Best
           Value needs to be based upon significant, as opposed to minor,
           technical considerations and/or a total price differential of at
           least the following: twenty percent (20%) in connection with RFPs for
           which the EarthWatch "should cost" analysis is $50 million or less;
           ten percent (10%) in connection with RFPs for which such "should
           cost" analysis is greater than $50 million but no more than $150
           million; and five percent (5%) in connection with RFPs for which such
           "should cost" analysis is more than $150 million. EarthWatch's
           notification will provide a clear, detailed statement of why the ITT
           Solicited Proposal does not offer Best Value, and offer good faith,
           constructive suggestions on how ITT could improve its proposal so
           that it does offer Best Value (including the possibility that ITT
           engage one or more specified subcontractors). In no event, however,
           will EarthWatch have any obligation to provide ITT with any
           information that EarthWatch receives on a confidential basis and
           under a duty or obligation of non-disclosure from other suppliers.
           Where suppliers exist whose inclusion as ITT subcontractors would
           result in the ITT Proposal offering Best Value, then EarthWatch's
           notification should state this fact and identify such suppliers.

     4.2.  Within twenty (20) days of receipt of an EarthWatch notification per
           (S)4.1, ITT may take any of the following actions:

           (i)   ITT may revise and resubmit the Solicited Proposal, which shall
                 represent a good faith effort on the part of ITT to satisfy the
                 requirements of a Best Value proposal and which EarthWatch will
                 then evaluate and consider as provided in (S)4.1;

           (ii)  ITT may inform EarthWatch that it declines to modify the
                 Solicited Proposal, in which case the provisions of (S)4.2.1
                 shall apply; or

           (iii) ITT may appeal EarthWatch's determination that a Solicited
                 Proposal does not represent Best Value in accordance with
                 (S)4.3.

     4.2.1 Upon notice of a second determination of Non-Best Value by
           EarthWatch, and following completion of the appeal process set forth
           in (S)4.3, it is agreed that ITT's Sensor prime contract will become
           a cost reimbursable contract with a 15% fixed fee. EarthWatch shall
           have the right to direct that a subcontract(s) be entered into with
           another supplier(s) to procure Sensor subsystem(s), which
           subsystem(s) would be integrated into the Sensor under ITT's Sensor
           systems integration prime contract.

     4.3.  For any determination by EarthWatch that an ITT Solicited Proposal
           does not provide Best Value, ITT may request in writing, within the
           time limits of Section 4.2 as applicable, an evaluation of
           EarthWatch's determination that the proposal

                                       4
<PAGE>

           does not represent Best Value. Such evaluation shall be submitted to
           a three person committee consisting of the then current EarthWatch
           CEO, an EarthWatch board member selected by ITT, and one Independent
           EarthWatch director selected by majority vote of Independent Earth
           Watch directors. For the purposes of this section, a director is
           Independent if he or she was not nominated, elected, or appointed by
           and has no association (as such term is defined in Rule 142(b)(2) to
           the Securities Act of 1933) with any party having any agreement with
           respect to the sale of goods to EarthWatch. ITT shall have a fair
           opportunity to make a presentation to this committee on why ITT
           believes that its Solicited Proposal constitutes Best Value. The
           finding of this committee shall be the definitive determination of
           Best Value, be rendered within fourteen (14) days by majority vote,
           and shall be transmitted to the EarthWatch board as a whole and
           recorded in the board minutes. If the committee finds that the
           proposal does represent Best Value, EarthWatch and ITT shall enter
           into a contract for the Sensor. If the committee finds that the
           proposal does not represent Best Value, then EarthWatch may proceed
           according to Section 2.5; provided that ITT shall have the one time
           right within 30 days of a decision to resubmit a revised proposal per
           (S)4.2.(i), and EarthWatch shall evaluate and consider the
           resubmitted proposal as provided in (S)4.1, with the provisions of
           Section 4.2 and this Section 4.3 again being applicable such second
           time.

5.   Term, Termination, Rights and Obligations Upon Termination - Section 5
     lists the conditions that constitute delay or default by either Party, the
     remedies available to each Party, the obligations of each Party, and the
     conditions for termination.

     5.1.  Term. This Agreement, unless terminated earlier, and subject to the
           ----
           provisions of this (S)5.1 herein below, shall continue for ten (10)
           years from the effective date of this Agreement. This Agreement,
           while effective, shall apply to all Sensors, the Procurement of which
           occurs or is commenced during the Term of the Agreement, whether or
           not the Sensor is intended to fly on a spacecraft during the Term of
           the Agreement; provided, however, that the Parties intend that this
           Agreement shall cover and apply to at least six (6) Sensors, and
           agree that the Term of this Agreement shall extend, and be extended,
           for up to five (5) additional years to the extent necessary or
           appropriate to encompass or apply to such six (6) Sensors. Except for
           a termination in accordance with (S)5.2 and (S)5.3, the provisions of
           this Agreement shall survive termination or expiration to the extent
           necessary or appropriate to give effect to the preceding sentence. At
           the termination of the Agreement, the obligations under (S)6.2 shall
           continue for five years.

     5.2.  Default by ITT: ITT is in default of this Agreement ("Default") if
           --------------
           ITT:

           5.2.1.  breaches any material provision of the Agreement, or any
                   resulting contract for a Sensor, and does not commence curing
                   such breach within forty-five (45) days of written notice
                   thereof, or if such breach is not capable of cure within such
                   forty-five (45) day period, undertake

                                       5
<PAGE>

                  and continue diligent efforts to cure, and cure such breach
                  within ninety (90) days; or

          5.2.2.  seeks protection under any bankruptcy, receivership, creditors
                  arrangement, composition or comparable proceeding, if any such
                  proceeding is instituted against ITT and is not dismissed
                  within sixty (60) days, or if ITT shall admit, before a court
                  of law, its inability to pay its debts as such debts become
                  due.

     5.3. Remedies for ITT Default: In the event of Default by ITT, EarthWatch
          ------------------------
          may terminate this Agreement and any resulting Sensor contract, and
          may pursue any remedies available under law, including the Uniform
          Commercial Code if applicable, and also including equitable remedies
          or relief such as (without limitation) specific performance, except
          that ITT will not be liable for any incidental, special, indirect, or
          consequential damages.

     5.4. Default by EarthWatch: EarthWatch is in default of this Agreement
          ---------------------
          ("Default") if EarthWatch:

          5.4.1.  breaches any material provision of the Agreement, or any
                  resulting contract for a Sensor, and does not commence curing
                  such breach within forty-five (45) days of written notice
                  thereof, or if such breach is not capable of cure within such
                  forty-five (45) day period, undertake and continue diligent
                  efforts to cure, and cure such breach within ninety (90) days;
                  or

          5.4.2.  seeks protection under any bankruptcy, receivership, creditors
                  arrangement, composition or comparable proceeding, or if any
                  such proceeding is instituted against EarthWatch and is not
                  dismissed within sixty (60) days, or if EarthWatch shall
                  admit, before a court of law, its inability to pay its debts
                  as such debts become due .

     5.5. Remedies for EarthWatch Default: In the event of Default by
          -------------------------------
          EarthWatch, ITT may terminate this Agreement and any resulting Sensor
          contract, and/or may pursue any remedies available under law,
          including the Uniform Commercial Code if applicable, and also
          including equitable remedies or relief such as (without limitation)
          specific performance, except that EarthWatch will not be liable for
          any incidental, indirect, special, or consequential damages.

6.   Miscellaneous Other Terms

     6.1. Use of ITT Systems as a Supplier:  During the Term of this Agreement,
          --------------------------------
          EarthWatch will agree to include ITT Systems, a division of ITT ("ITT
          Systems"), on its list of preferred suppliers for custom efforts in
          those areas in which EarthWatch is aware that ITT Systems has
          resources and expertise. Possible areas include, but are not limited
          to, work, support and/or services related to:

                                       6
<PAGE>

          .    Development of ground command and control systems;

          .    Spacecraft simulator development;

          .    Satellite scheduling and tasking software;

          .    Earth ground stations which EarthWatch might undertake or
               commence beyond QuickBird 1 and 2; and

          .    Launch services and processing support for EarthWatch's
               satellites and/or payloads which EarthWatch might undertake or
               commence beyond QuickBird 1 and 2.

          6.1.1.    As reasonable, EarthWatch will notify ITT Systems of, and
                    furnish ITT Systems on a timely basis with, any competitive
                    requests for proposals released by EarthWatch relating to
                    those scopes in which ITT Systems has competencies known to
                    EarthWatch. Requests relating to standard off-the-shelf
                    products and requests that do not represent an opportunity
                    for ITT Systems to receive an award will not be furnished to
                    ITT Systems. EarthWatch will consider ITT Systems for the
                    award of a contract for compliant proposals submitted by ITT
                    Systems in response to such requests.

          6.1.2.    Both parties acknowledge that EarthWatch has existing
                    relationships with suppliers in some of the areas in which
                    ITT Systems possesses resources and expertise. Nothing in
                    this Section creates an obligation on the part of EarthWatch
                    to eliminate or alter such relationships.

     6.2. Mutual Confidentiality:  The Parties agree that all code, inventions,
          ----------------------
          algorithms, know-how and ideas and all other business, technical and
          financial information they obtain from the other Party are the
          confidential property of the disclosing Party ("Proprietary
          Information" of the disclosing Party). Except as expressly and
          unambiguously allowed therein, and except as might be required to
          comply with a court order or subpoena or other government directive or
          requirement, the receiving Party will hold in confidence and not use
          other than for the intended purpose or disclose any Proprietary

                   arbitrator shall decide the matters submitted based upon the
                   evidence presented and the terms of this Agreement. Such
                   arbitrator shall issue a written award which shall state the

                   Federal Arbitration Act, (ii) where the arbitrator's findings
                   of fact are not supported by substantial evidence, or (iii)
                   where the arbitrator's conclusions of law are erroneous.

           6.13.6. Injunctive Relief: Except as limited by Section 4.3, nothing
                   -----------------
                   contained in this Section 6.13 shall prevent either Party
                   from seeking injunctive relief from any court of competent
                   jurisdiction prior to, during, or in addition to such
