DIGITALGLOBE, INC.

Investor Agreement

          This Investor Agreement (this “Agreement”) is made as of July 14, 2008, between DigitalGlobe, Inc., a Delaware corporation (the “Company”), and Morgan Stanley & Co. Incorporated, a Delaware corporation (including its successors or permitted assigns, the “Stockholder”). Unless otherwise specified herein, all of the capitalized terms used herein are defined in Section 5 hereof.

          WHEREAS, as of the date hereof the Stockholder owns beneficially and of record 82,895,120 shares of common stock, par value, $0.001 per share, of the Company (the “Common Stock”);

          WHEREAS, the Company is contemplating an offer and sale of its Common Stock to the public in an underwritten initial public offering (the “IPO”) registered under the Securities Act of 1933, as amended from time to time, and the rules promulgated thereunder (the “Securities Act”);

          WHEREAS, the Company and certain stockholders of the Company, including the Stockholder, entered into that certain Stockholders’ Agreement, dated as of July 9, 2003 (the “Stockholders Agreement”), certain terms of which shall remain in effect after consummation of the IPO; and

          WHEREAS, the Company and the Stockholder desire to enter into this Agreement to govern certain aspects of their relationship upon the consummation of an IPO.

          NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows:

	1.		Effectiveness. The parties are entering into this Agreement in connection with a currently proposed IPO. This Agreement shall become automatically effective upon the consummation of the IPO (the “Effective Time”).
	2.		Board of Directors.

	(a)		Upon completion of the IPO, the Board of Directors of the Company (the “Board”) shall initially consist of nine persons who shall be divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board.
	(b)		From and after the Effective Time and subject to the terms and conditions of this Agreement, the Stockholder shall have the right to designate persons to be nominated for election to the Board (each a “Nominee”) as follows:

i. For so long as the Stockholder and/or any of its Affiliates is the record and beneficial owner of Stockholder Shares representing at least 25% of

the outstanding Common Stock, five representatives designated by the Stockholder, who shall be initially Eddy Zervigon (Non-Independent), Paul M. Albert (Independent), Warren C. Jenson (Independent), [to be named] and [to be named] (the “MS Directors”); provided that no more than two Nominees shall not be Independent;

ii. For so long as the Stockholder and/or any of its Affiliates is the record and beneficial owner of Stockholder Shares representing less than 25% but at least 20% of the outstanding Common Stock, four representatives designated by the Stockholder; provided that no more than one Nominee shall not be Independent; and

iii. For so long as the Stockholder and/or any of its Affiliates is the record and beneficial owner of Stockholder Shares representing less than 20% but at least 15% of the outstanding Common Stock, three representatives designated by the Stockholder; provided that each of the Nominees shall be Independent.

For the avoidance of doubt, references to outstanding Common Stock shall not include shares reserved for issuance pursuant to options, convertible securities or other similar rights.

For purposes of this Section 2(b), any determination required to be made hereunder as to beneficial ownership of the Stockholder Shares shall be made at the end of each of the Company’s fiscal quarters. The Company shall promptly notify the Stockholder in writing upon the Company’s determination that a Reduction Event (as defined below) has been deemed to occur.

	(c)		The MS Directors will serve as a Class I, Class II or Class III directors (as defined in the Company’s Certificate of Incorporation) as set forth on Annex A attached hereto. The initial term of each Class I, Class II and Class III Director shall expire as set forth in the Company’s Certificate of Incorporation.
	(d)		In the event of any increase or decrease in the size of the Board (other than as contemplated by Section 2(e)), the numbers of Nominees that the Stockholder shall have the right to designate pursuant to the applicable provision of Section 2(b) (the “Initial Numbers”) shall be adjusted such that the numbers of Nominees shall represent, as closely as possible, the same percentages of the resulting full Board as the Initial Numbers shall represent as a percentage of the full initial Board.
	(e)		Each time that the ownership of Stockholder Shares by the Stockholder of Common Stock is reduced below a level at which, pursuant to Section 2(b) there would be a reduction in the number of Nominees which the Stockholder would be entitled to designate (a “Reduction Event”), the Stockholder shall cause one or more of its non-Independent Nominees to resign from the Board at the next annual meeting of stockholders such that following such resignation the remaining number of Nominees shall be equal to the number of Nominees that the Stockholder is entitled to designate in accordance with Section 2(b) after giving effect to such reduced ownership. At such time when the Stockholder and/or any of its Affiliates is the record and beneficial owner of Stockholder

			Shares representing less than 15% of the outstanding Common Stock, the Stockholder shall no longer have any right to designate any Nominee under Section 2(b) hereof, but those Independent directors previously nominated by Stockholder and currently serving may serve out their current terms. The resulting vacancy(ies) may be filled by the Board or the Board may elect to reduce the size of the full Board in order to eliminate such vacancy(ies). As a condition to designating any Nominee, the Stockholder shall obtain the binding commitment of the Nominee to resign to the extent required by this Section 2(e) and requested by the Stockholder and/or the Board. For the sake of clarity, it is expressly understood and agreed that upon the occurrence of each Reduction Event, any subsequent acquisition of Common Stock by the Stockholder and/or any of its Affiliates shall not result in an increase to the number of Nominees that the Stockholder is entitled to designate regardless of whether such subsequent acquisition would result in the record and beneficial ownership by the Stockholder and/or any of its Affiliates of a percentage of the outstanding Common Stock increasing to a level which would entitle the Stockholder to designate additional Nominees pursuant to Section 2(b).
	(f)		If a vacancy occurs because of the death, disability, disqualification, resignation or removal of a Nominee (except as contemplated by Section 2(e)), subject to Section 4(c), the Stockholder shall be entitled to designate such Nominee’s successor in accordance with this Agreement and the Board, subject to a determination of the Board in good faith, after consultation with outside legal counsel, that such action would not constitute a breach of its fiduciary duties or applicable law or violate the Company’s Certificate of Incorporation, by-laws, corporate governance guidelines or similar policies and that such Nominee, to the extent required under Section 2(b), is Independent, shall fill the vacancy with such successor Nominee.

	3.		Board Committees. From and after the Effective Time and subject to the terms and conditions of this Agreement, at least one of the Stockholder’s Nominees shall be appointed to each of the standing committees of the Company; provided that each Nominee appointed meets any independence or other requirements of the national securities exchange on which the Company’s Common Stock is listed.
	4.		Company Obligations.

	(a)		The Company agrees to use its best efforts to assure that (i) each Nominee is included in the Board’s slate of nominees to the stockholders for each election of directors, and (ii) each Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of the Board, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board (to the extent permitted) with respect to the election of members of the Board.
	(b)		Notwithstanding anything herein to the contrary, the Company shall not be obligated to cause to be nominated for election to the Board or recommend to the stockholders the election of any Nominee (i) who fails to submit to the Company on a timely basis such questionnaires as the Company may reasonably require of

			its directors generally and such other information as the Company may reasonably request in connection with the preparation of its filings under the Securities Laws; or (ii) the Board or any committee thereof determines in good faith, after receipt of written advice of outside legal counsel, that such action would constitute a breach of its fiduciary duties or applicable law or violate the Company’s Certificate of Incorporation, by-laws, corporate governance guidelines or similar policies, or that such Nominee, to the extent required under Section 2(b), is reasonably likely not to be Independent; provided, however, that upon the occurrence of either (i) or (ii) above, the Company shall promptly notify the Stockholder of the occurrence of such event and, to the extent possible, permit the Stockholder to provide an alternate Nominee sufficiently in advance of any Board action or meeting of stockholders called with respect to such election of nominees or consent in lieu of a meeting. The Company shall use best efforts to perform its obligations under Section 4(a) with respect to such alternate Nominee; provided, however, that if the Company provides at least 60 days advance notice of the occurrence of any such event such alternative nominee must be designated by the applicable Stockholder not less than 30 days in advance of any Board action or notice of meeting of the stockholders; provided, further, in no event shall the Company be obligated to postpone, reschedule or delay any scheduled meeting of the stockholders or to amend or supplement any proxy statement with respect to such election of directors provided the Company has otherwise complied with this Section 4.
	(c)		At any time a vacancy occurs because of the death, disability, resignation or removal of a Nominee, then the Board, or any committee thereof, shall not fill such vacancy until the earliest to occur of (i) such Stockholder has designated a successor Nominee and the Board has filled the vacancy and appointed such successor Nominee in accordance with Section 2(f) above; (ii) such Stockholder fails to designate a successor Nominee within 30 days after receiving written notification of the vacancy from the Company; or (iii) such Stockholder has specifically waived its right under this Section 4(c).
