(d) The closing of the exchange of MDA Shares for Orbital Stock (the "EXCHANGE") shall take place on a date (the "EXCHANGE DATE") designated by Orbital, not later than 30 days after the date on which the first Notice of Exchange is delivered to Orbital, at such location as the parties may mutually agree upon and subject to the satisfaction or waiver of all conditions to the Exchange set forth in ARTICLE 5 hereof.

The Exchange Right shall be void on June 23, 2002 in the event that a Trigger Date has not occurred as of such date. 2.3. EXCHANGE RATE The exchange rate for which the MDA Shares to be exchanged by an Investor are exchangeable for Orbital Stock (the "EXCHANGE RATE") shall be as follows: X = A x B ----- C Where: X = the number of shares of Orbital Stock to be issued to an Investor; A = the number of MDA Shares to be exchanged by such Investor; B = the price at which such Investor purchased the MDA Shares at the Initial Closing; and C = the lesser of (I) the Fair Market Price of one share of Orbital Stock on the date of delivery of the applicable Notice of Exchange and (II) U.S. $25.00; provided, however, that the Fair Market Price of one share of Orbital Stock shall in no event be less than U.S. $13.00 per share. 7 8 In the event that the Fair Market Price of one share of Orbital Stock would have been less than U.S. $13.00 per share (the "LOWER MARKET PRICE"), then Orbital, at its option, shall either (i) provide additional shares of Orbital Stock to the exchanging Investor as if such proviso were deleted or (ii) pay to the exchanging Investor an amount in cash equal to the product of (x) the difference between the number of shares of Orbital Stock that would have been received by the exchanging Investor had the proviso been deleted and the number of shares of Orbital Stock actually received (including any fractions), times (y) the Lower Market Price. 2.4. ADJUSTMENTS TO ORBITAL STOCK. The number of shares of Orbital Stock which may be exchanged pursuant to SECTION 2.3 are subject to adjustment from time to time as follows: 2.4.1.

The foregoing provisions of this SECTION 2.4.1 shall similarly apply to successive reorganizations, consolidations, mergers, sales and transfers. 2.4.2. RECLASSIFICATION, ETC. If Orbital, at any time prior to the exercise or expiration of the Exchange Right, by reclassification of securities or otherwise, shall change any of the securities as to which Exchange Rights exist into the same or a different number of securities of any other class or classes, this Agreement shall thereafter represent the right to exchange such number and kind of securities as would have 8 9 been issuable as the result of such change with respect to the securities that were subject to the exchange rights under this Agreement immediately prior to such reclassification, all subject to further adjustment as provided in this SECTION 2.4. 2.4.3. SPLIT, SUBDIVISION OR COMBINATION OF SHARES. If Orbital, at any time prior to the exercise or expiration of the Exchange Right, shall split, subdivide or combine the securities as to which Exchange Rights exist, into a different number of securities of the same class, the number of shares of such securities that are exchangeable pursuant to this Agreement may be exercised shall be proportionately increased, in the case of a split or subdivision, or shall be proportionately decreased, in the case of a combination. 2.4.4. CERTIFICATE AS TO ADJUSTMENTS. Upon the occurrence of each adjustment or readjustment pursuant to this SECTION 2.4, Orbital at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Investor a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. 2.4.5. FRACTIONAL SHARES. No fractional shares of Orbital Stock shall be issued upon exchange of the MDA Shares. Instead of any fractional interest in a share of Orbital Stock, Orbital shall calculate and pay to the holder of such share a cash adjustment in respect of such fraction in an amount based on the Current Market Price of the Orbital Stock on the trading day immediately preceding the date of exchange. 2.5. ADJUSTMENTS TO MDA SHARES If any of the events described in SECTION 2.4 of this Agreement shall occur with respect to MDA, similar adjustments shall be made to the MDA Shares for purposes of the Exchange Rate set forth in SECTION 2.3. 3.

(f) Any required governmental approvals shall have been obtained on terms reasonably satisfactory to Orbital and the Investors. 5.2. CONDITIONS TO THE INVESTORS' OBLIGATIONS. The obligations of the Electing Investors upon the exercise of an Exchange Right are subject to the satisfaction or waiver by the Investors on or before the applicable Exchange Date of each of the following conditions: (a) The representations and warranties of Orbital set forth in this Agreement shall be true and correct on and as of such Exchange Date with the same effect as though such representations and warranties had been made on and as of such date. (b) Orbital shall have performed and complied in all material respects in accordance with its terms with all agreements, obligations and conditions contained in this Agreement that are required to be performed or complied with by it on or before such Exchange Date. (c) Orbital shall have delivered to the Electing Investors on such Exchange Date a certificate, signed by an executive officer of Orbital to the effect that the conditions set forth in SECTIONS 5.2(a) and 5.2(b) have been satisfied as of the Exchange Date. (d) There shall not be in effect any order, decree or injunction of a court or agency of competent jurisdiction which enjoins or prohibits consummation of the transactions contemplated hereby and there shall be no actual or threatened action, suit, arbitration, inquiry, proceedings or investigation by or before any governmental authority, court or agency of competent jurisdiction, which would 16 17 reasonably be expected to materially impair the ability of Orbital or the Investors to consummate the transactions contemplated hereby. (e) Any required governmental approvals shall have been obtained on terms reasonably satisfactory to Orbital and the Investors. 6. REGISTRATION RIGHTS. 6.1. DEMAND REGISTRATION. (a) The Holder or Holders of Registrable Shares constituting at least 1,500,000 outstanding Registrable Shares (together with all other Shareholders joining in such demand as provided below, the "INITIAL REQUESTING HOLDERS"), may at any time make a written request to Orbital that Orbital file a Registration Statement or similar document under the Act with respect to all or any part of such Holder's or Holders' Registrable Shares (a "DEMAND REGISTRATION"). Such Registration shall be a "shelf" Registration Statement pursuant to Rule 415 under the Act (or a successor provision), if so requested by a majority of the participating Holders and if Orbital is eligible therefore at such time (for greater certainty, the Registration Statement need not be a Shelf Registration Statement). Within 10 Business Days after receipt of such request, Orbital shall give written notice of such Demand Registration request (including therein the number of Registrable Shares included in such demand and the parties making such demand) to all other Holders of Registrable Shares (the "DEMAND NOTICE"). Such other Holders will have the right to join in making such a demand by giving written notice to Orbital within 10 Business Days after the date of the Demand Notice of such Holder's election to participate in such Demand Registration and the number of such Holder's Registrable Shares to be included therein. Subject to the provisions of SECTION 6.1(b), Orbital shall cause such Registration Statement or similar document to be filed with the Commission and shall include in such Registration Statement the Registrable Shares which Orbital has been requested to register by the Initial Requesting Holders, and to cause all such Registrable Shares to be registered under the Act within 180 days of receipt of the Initial Requesting Holders' request. After Orbital has effected three (3) such registrations pursuant to this SECTION 6.1(a), the related Registration Statements have been declared effective and the distribution contemplated thereunder completed within the time frame specified in Section 6.1(b), Orbital shall have no further obligation under this SECTION 6.1(a); provided, however, that no Holder shall be entitled to have the Registrable Shares held by it covered by such Registration unless such Holder is in compliance with SECTION 6.3(j) hereof. No Demand Registration shall be effected pursuant to this SECTION 6.1(a) during any period in which a Registration Statement shall have become and be maintained effective. 17 18 (b) Orbital shall use its reasonable best efforts to keep each such Shelf Registration continuously effective in order to permit the Prospectus forming part thereof to be usable by the Holders until the earlier of (A) the date when all the Registrable Shares have been sold pursuant to such Shelf Registration Statement or Rule 144 and (B) the date on which, in the written opinion of counsel to the Holders addressed to the Holders and to Orbital, all outstanding Registrable Shares of Orbital are eligible for resale without registration under the Act in accordance with Rule 144(k) or any successor provision thereto (in any such case, such period being called the "EFFECTIVENESS PERIOD"). Orbital shall be deemed not to have used their reasonable best efforts to keep the Registration Statement effective during the requisite period if Orbital voluntarily takes any action that would result in Holders covered thereby not being able to offer and sell any such Registrable Shares during that period, unless (x) such action is required by applicable law or the rules of any national securities exchange or other market on which any of the Registrable Shares are then listed or quoted, or (y) any event contemplated by SECTION 6.3(b)(2)(iii) below occurs and Orbital acts promptly in good faith and for valid business reasons in suspending use of the Prospectus until the requisite changes have been made and Orbital thereafter promptly complies with the requirements of SECTION 6.3(h) below. (c) Notwithstanding anything to the contrary contained in this ARTICLE 6, Orbital shall have the right (the "SUSPENSION RIGHT") to defer such filing (or suspend sales under any filed registration thereunder) for a period of not more than 90 days during any 12-month period (a "BLACK-OUT PERIOD"), if Orbital shall furnish to the Holders a certificate signed by the President or any other executive officer of Orbital stating that, either (i) in the good faith judgment of Orbital, the continued effectiveness of the Registration Statement would require Orbital to disclose a material financing, acquisition or other corporate transaction, and the Board of Directors shall have determined in good faith that it would be detrimental to Orbital and its shareholders to file such Registration Statement or amendment thereto at such time (or continue sales under a filed Registration Statement) or (ii) Orbital plans to conduct an underwritten offering of its equity securities during such Black-Out Period and, in each case, therefore, Orbital has elected to defer the filing of such Registration Statement (or suspend sales under a filed Registration Statement) provided, however, that Orbital shall have the obligation (with respect to both (i) and (ii) of this Section 6.1(c)) to file any such deferred Registration Statement or lift any suspension of sales under a filed Registration Statement as soon as such filing is no longer detrimental, and in such circumstances, the Holder can withdraw the Demand Registration without prejudice to making it again. (d) Orbital agrees not to issue any Orbital Stock or any securities convertible into or exchangeable or exercisable for Orbital Stock (other than securities issued pursuant to Orbital's option or other benefit plans, its 5% Convertible Subordinated Notes Due 2002, securities issued by Orbital not 18 19 involving a public offering or securities issued by Orbital included in any Demand Registration), for the period commencing 15 days prior to the closing of the offering of securities included in any Demand Registration and ending on the 90th day following such closing. 6.2. ORBITAL REGISTRATION (a) If Orbital shall determine to register any shares of Orbital Stock for its own account or for the account of a security holder or holders or otherwise (other than a registration relating solely to employee benefit plans, or a registration relating solely to a merger, exchange offer or a transaction of the type specified in Rule 145(a) under the Act), Orbital will promptly deliver to each of the Holders a written notice thereof of such proposed transaction at least 10 Business Days prior to the filing of a Registration Statement (the "ORBITAL REGISTRATION STATEMENT") and include in such registration, and in any underwriting involved therein, all the Registrable Shares specified in written requests made by Holders within 10 Business Days after receipt of the written notice from Orbital described above. Each Holder shall be entitled to have its shares included in an unlimited number of registrations pursuant to this SECTION 6.2. (b) If the registration of which Orbital gives notice is for a registered public offering involving an underwriting, Orbital shall so advise the Holders as a part of the written notice given pursuant to SECTION 6.2(a). In such event, the right of each Holder to registration pursuant to SECTION 6.2(a) shall be conditioned upon such Holder's participation in such underwriting and the inclusion of the Registrable Shares in the underwriting to the extent provided herein. If the Holders shall have elected to exercise their rights under SECTION 6.2(a), they shall enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for underwriting by Orbital. Notwithstanding any other provision of this SECTION 6.2, if the underwriter determines and so advises Orbital in writing that marketing factors require a limitation on the number of shares to be underwritten, Orbital shall so advise the Holders. In such an event, the number of Registrable Shares that may be included in the registration and underwriting by the Holders shall be reduced, on a pro rata basis (based on the number of shares of Orbital Stock held by each such Holder and each other person (other than Orbital) registering shares under such registration), by such minimum number of shares as is necessary to comply with such limitation. If a Holder disapproves of the terms of any such underwriting, it may elect to withdraw therefrom by written notice to Orbital and the underwriter. Any Registrable Shares excluded or withdrawn from such underwriting shall be withdrawn from such registration. 19 20 6.3. REGISTRATION PROCEDURES. (a) Orbital shall furnish to the Exercising Holders, prior to the filing thereof with the Commission, a copy of any Registration Statement, and each amendment thereof or supplement, if any, to the Prospectus included therein and shall use its reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments that the Exercising Holders reasonably may propose. (b) (1) Orbital shall advise the Exercising Holders: (i) when a Registration Statement and any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective; and (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the Prospectus included therein or for additional information. (2) Orbital shall advise the Exercising Holders of: (i) the issuance by the Commission of any stop order suspending effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (ii) the receipt by Orbital of any notification with respect to the suspension of the qualification of the securities included therein for sale in any jurisdiction or the initiation of any proceeding for such purpose; and (iii) the happening of any event that requires the making of any changes in the Registration Statement or the Prospectus so that, as of such date, the Registration Statement and the Prospectus do not contain an untrue statement of a material fact and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading (which advice shall be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made). (c) Orbital shall use its reasonable best efforts to prevent the issuance, and if issued to obtain the withdrawal, of any order suspending the effectiveness of any Registration Statement at the earliest possible time. (d) Orbital shall furnish to each Holder, without charge, at least one copy of such Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Holder so requests in writing, all reports, other documents and exhibits (including those incorporated by reference). (e) Orbital shall, during the Effectiveness Period, deliver to each Exercising Holder, without charge, as many copies of the Prospectus (including each preliminary Prospectus) included in such Registration Statement and any amendment or supplement thereto as such Exercising Holder may reasonably 20 21 request; and Orbital consents (except upon and during the continuance of any event described in SECTION 6.3(b)(2)(iii) above) to the use of the Prospectus or any amendment or supplement thereto by each of the selling Exercising Holders in connection with the offering and sale of the Registrable Shares covered by the Prospectus or any amendment or supplement thereto during the Effectiveness Period. (f) Prior to any offering of Registrable Shares pursuant to any Registration Statement, Orbital shall register or qualify or cooperate with the Exercising Holders included therein and their respective counsel in connection with the registration or qualification of such Registrable Shares for offer and sale under the securities or blue sky laws of such jurisdictions as any such Exercising Holders reasonably request in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such United States jurisdictions of the Registrable Shares covered by such Registration Statement; provided, however, that in no event shall Orbital be obligated to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it would not otherwise be qualified or required to so qualify but for this SECTION 6.3(f), (ii) file any general consent to service of process in any jurisdiction where it is not as of the date hereof then so subject or (iii) subject itself to taxation in any such jurisdiction if it is not then so subject. (g) Orbital shall cooperate with the Exercising Holders to facilitate the timely preparation and delivery of certificates representing Registrable Shares to be sold pursuant to any Registration Statement free of any restrictive legends and in such permitted denominations and registered in such names as Exercising Holders may request in connection with the sale of Registrable Shares pursuant to such Registration Statement. (h) Upon the occurrence of any event contemplated by SECTION 6.3(b)(2)(iii) above, Orbital shall promptly, and in any event within 30 days, subject to SECTION 6.1(c), prepare a post-effective amendment to any Registration Statement or an amendment or supplement to the related Prospectus or file any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. If Orbital notifies the Exercising Holders of the occurrence of any event contemplated by SECTION 6.3(b)(2)(iii) above, the Exercising Holders shall suspend the use of the Prospectus until the requisite changes to the Prospectus have been made. (i) Orbital shall use its best efforts to comply with all applicable rules and regulations of the Commission and shall make generally available to their security holders or otherwise provide in accordance with Section 11(a) of the Act as 21 22 soon as practicable after the effective date of the applicable Registration Statement an earnings statement satisfying the provisions of Section 11(a) of the Act. (j) Orbital agrees to use its reasonable best efforts (including the payment of any listing fees) to obtain the listing of all Registrable Shares covered by the Registration Statement on each securities exchange on which securities of the same class are then listed. (k) If the Exercising Holders propose to sell their Registrable Shares pursuant to SECTION 6.1 in an underwritten public offering, Orbital shall be entitled to select the underwriters for such offering, subject to the reasonable approval of a majority of the participating Holders, and Orbital shall make available members of the management of Orbital and its Affiliates for reasonable assistance in selling efforts relating to such offering for a public offering of such size and shall enter into underwriting agreements containing usual and customary terms and conditions for such types of offerings; provided that Orbital shall not be required to assist in an underwritten offering more than once in any 12-month period. 6.4. EXPENSES OF REGISTRATION. Orbital shall pay, or shall reimburse each Holder for paying, all Registration Expenses incurred in connection with the registration of the Registrable Shares in accordance with SECTIONS 6.1 and 6.2 hereof and the reasonable fees and expenses of one special counsel, in each country and province where the shares are being registered, for the Holders, which special counsel(s) shall be designated by the Holders and subject to the approval of the Company, in an amount not to exceed $35,000 per Registration pursuant to SECTION 6.1 and an aggregate of $150,000 for all Registrations under SECTIONS 6.1 and 6.2. All Selling Expenses incurred in connection with the offer and sale of Registrable Shares by any of the Holders shall be borne by the Holder offering or selling such Registrable Shares. Except as covered by the first sentence of this SECTION 6.4, each Holder shall pay the expenses of its own counsel. 6.5. INDEMNIFICATION. (a) In connection with any Registration Statement, Orbital shall indemnify and hold harmless each Exercising Holder and each of their respective directors and officers and each person controlling such Exercising Holder within the meaning of Section 15 of the Act from and against any loss, liability, claim, damage and expense whatsoever, including any amounts paid in settlement of any investigation, litigation, proceeding or claim, joint or several, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) covering Registrable Shares, including all documents incorporated therein by reference, or 22 23 the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that Orbital shall not be liable under this clause (a) for any settlement of any action effected without its written consent, which consent shall not be unreasonably withheld or delayed; provided further, that the indemnity provided for in this SECTION 6.5(a) shall not apply to any loss, liability, claim, damage or expense to the extent arising out of an untrue statement or omission or alleged untrue statement or omission (i) made in reliance upon and in conformity with written information furnished to Orbital by such Exercising Holder in writing expressly stating that such information is being provided by such Exercising Holder for use in the Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto) or (ii) contained in any preliminary prospectus or the Prospectus if such Exercising Holder failed to send or deliver a copy of the Prospectus (or any amendment or supplement thereto) to the person asserting such losses, claims, damages or liabilities on or prior to the delivery of written confirmation of any sale of securities covered thereby to such person in any case where such Prospectus (or any amendment or supplement thereto) corrected such untrue statement or omission. Any amounts advanced by Orbital to an indemnified party pursuant to this SECTION 6.5 as a result of such losses shall be returned to Orbital if it shall be finally determined by such a court in a judgment not subject to appeal or final review that such indemnified party was not entitled to indemnification by Orbital. (b) Each Exercising Holder, severally and not jointly, shall indemnify and hold harmless Orbital and the other Exercising Holders and each of their respective directors and officers (including each officer of Orbital who signed the Registration Statement) and each person, if any, who controls Orbital or other selling Holder within the meaning of Section 15 of the Act, from and against any loss, liability, claim, damage and expense whatsoever described in the indemnity contained in SECTION 6.5(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to Orbital by such Exercising Holder in writing expressly stating that such information is being provided by such Holder for use in the Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto); provided that the Exercising Holder shall not be liable under this clause for any settlement of any action effected without its written consent, which consent shall not be unreasonably withheld. Notwithstanding any provision of this Agreement or any other agreement, in no event will any Investor be liable for indemnification hereunder for an amount 23 24 greater than the amount of proceeds that such Investor receives in any particular offering of Registrable Securities in which his securities were sold. (c) Each party entitled to indemnification under this SECTION 6.5 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, but the omission to so notify the Indemnifying Party shall not relieve it from any liability which it may have to the Indemnified Party pursuant to the provisions of this SECTION 6.5 except to the extent of the actual damages suffered by such delay in notification. The Indemnifying Party shall assume the defense of such action, including the employment of counsel to be chosen by the Indemnifying Party to be reasonably satisfactory to the Indemnified Party, and payment of expenses. The Indemnified Party shall have the right to employ its own counsel in any such case, but the legal fees and expenses of such counsel shall be at the expense of the Indemnified Party, unless the employment of such counsel shall have been authorized in writing by the Indemnifying Party in connection with the defense of such action, or the Indemnifying Party shall not have employed counsel to take charge of the defense of such action or the Indemnified Party shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to the Indemnifying Party (in which case the Indemnifying Party shall not have the right to direct the defense of such action on behalf of the Indemnified Party), in any of which events such fees and expenses shall be borne by the Indemnifying Party. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (d) If the indemnification provided for in this SECTION 6.5 is unavailable to a party that would have been an Indemnified Party under this SECTION 6.5 in respect of any expenses, claims, losses, damages and liabilities referred to herein, then each party that would have been an Indemnifying Party hereunder shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such expenses, claims, losses, damages and liabilities in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and such Indemnified Party on the other in connection with the statement or omission which resulted in such expenses, claims, losses, damages and liabilities, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Indemnifying Party or such Indemnified Party and the parties' relative intent, knowledge, access to information and opportunity to correct 24 25 or prevent such statement or omission. Orbital and each Exercising Holder agrees that it would not be just and equitable if contribution pursuant to this Section were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this SECTION 6.5(d). (e) No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 6.6. INFORMATION TO BE FURNISHED BY HOLDERS. Each Holder shall furnish to Orbital such information as Orbital may reasonably request and as shall be required in connection with the Registration and related proceedings referred to in SECTIONS 6.1 and 6.2 hereof. If any Holder fails to provide Orbital with such information within 15 Business Days of Orbital's request, Orbital's obligations under SECTIONS 6.1 and 6.2 hereof with respect to such Holder or the Registrable Shares owned by such Holder shall be suspended until such Holder provides such information. 6.7. RULE 144 SALES. (a) Orbital covenants that it will file the reports required to be filed by Orbital under the Exchange Act, so as to enable any Holder to sell Registrable Shares pursuant to Rule 144 under the Act. (b) In connection with any sale, transfer or other disposition by any Holder of any Registrable Shares pursuant to Rule 144 under the Act, Orbital shall cooperate with such Holder to facilitate the timely preparation and delivery of certificates representing Registrable Shares to be sold and not bearing any Act legend, if deemed appropriate, and enable certificates for such Registrable Shares to be for such number of shares and registered in such names as the selling Holder may reasonably request, provided that such request is made at least two Business Days prior to any sale of Registrable Shares. 7. MISCELLANEOUS 7.1. RIGHTS OF STOCKHOLDERS. Until the Exchange Right shall have been exercised as provided herein, the Investors, as such, shall not be entitled to vote or receive dividends or any other securities of Orbital that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Investors, as such, any of the rights of a stockholder of Orbital or any right 25 26 to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, or change of stock to no par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise. 7.2. SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties hereto. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement. 7.3. AMENDMENTS AND WAIVERS. Any term of this Agreement may be amended, and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of each party. 7.4. NO WAIVER. No delay or omission to exercise any right, power, or remedy accruing to either party upon any breach or default under this Agreement, shall be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent, or approval of any kind or character on the part of either party of any breach or default under this Agreement, or any waiver on the part of either party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to either of the parties, shall be cumulative and not alternative. 7.5. NOTICES. Unless otherwise provided, any notice required or permitted under this Agreement shall be given in writing and shall be deemed effectively given (a) upon personal delivery to the party to be notified, (b) on the day of receipt if delivered by registered or certified mail, (c) on the next Business Day after dispatch via nationally recognized overnight courier or (d) upon confirmation of transmission by facsimile, all addressed to the party to be notified.
