 3. Registration. 
 (a) Registration on Form S-1. As promptly as reasonably practicable after the date on which the Majority Holders request in writing (the “Demand Date”), but in any
event not later than 180 days after such date ( the “Registration Filing Date”), the Company shall use its commercially reasonable efforts to file with the Commission a registration statement on Form S-1 relating to
the resale by the Holders of all of the Registrable Securities; provided, however, that the Company shall not be obligated to effect any such registration, qualification, or compliance pursuant to this Section 3(a), or keep such
registration effective pursuant to Section 4: (i) in any particular jurisdiction in which the Company would be required to qualify to do business as a foreign corporation or as a dealer in securities under the securities or blue sky laws
of such jurisdiction or to execute a general consent to service of process in effecting such registration, qualification or compliance, in each case where it has not already done so; or (ii) during any Blackout Period, in which case the
Registration Filing Date shall be extended to the date immediately following the last day of such Blackout Period. 
 (b)
Piggyback Registration. If the Company shall determine to register for sale for cash any of its Common Stock, for its own account or for the account of others (other than the Holders) pursuant to the exercise of demand registration rights,
other than (i) a registration relating solely to employee benefit plans or securities issued or issuable to employees, consultants (to the extent the securities owned or to be owned by such consultants could be registered on Form S-8) or
any of their Family Members (including a registration on Form S-8) or (ii) a registration relating solely to a Commission Rule 145 transaction, a registration on Form S-4 in connection with a merger, acquisition, divestiture,
reorganization, or similar event, the Company shall promptly give to the Holders written notice thereof (and in no event shall such notice be given less than 20 calendar days prior to the filing of such registration statement), and shall, subject to
Section 3(c), include in such registration (and any related qualification under blue sky laws or other compliance) (a “Piggyback Registration”), all of the Registrable Securities specified in a written request or
requests, made within 10 calendar days after receipt of such written notice from the Company, by any Holder or Holders. However, the Company may, without the consent of the Holders, withdraw such registration statement prior to its becoming
effective if the Company or such other shareholders have elected to abandon the proposal to register the securities proposed to be registered thereby. 
 (c) Underwriting. If a Piggyback Registration is for a registered public offering involving an underwriting, the Company shall so advise the Holders in writing or as a part of the written notice
given pursuant to Section 3(b). In such event the right of any Holder to registration pursuant to Section 3(b) shall be conditioned upon

  

 3 

 
such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the Company and any other shareholders of the Company distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by the Company or selling shareholders, as applicable. Notwithstanding any other provision of this Section 3(c), if the underwriter or the Company determines that marketing factors
require a limitation of the number of shares to be underwritten, the underwriter may exclude some or all Registrable Securities from such registration and underwriting. The Company shall so advise all Holders (except those Holders who failed to
timely elect to distribute their Registrable Securities through such underwriting or have indicated to the Company their decision not to do so), and the number of shares of Registrable Securities that may be included in the registration and
underwriting, if any, shall be allocated among such Holders as follows: 
 (i) In the event of a Piggyback Registration that is
initiated by the Company, the number of shares that may be included in the registration and underwriting shall be allocated first to the Company and then, subject to obligations and commitments existing as of the date hereof, to all selling
shareholders, including the Holders, who have requested to sell in the registration on a pro rata basis according to the number of shares requested to be included; and 
 (ii) In the event of a Piggyback Registration that is initiated by the exercise of demand registration rights by a shareholder or shareholders of the Company (other than the Holders), then the number of
shares that may be included in the registration and underwriting shall be allocated first to such selling shareholders who exercised such demand and then, subject to obligations and commitments to all other selling shareholders, including the
Holders, who have requested to sell in the registration, on a pro rata basis according to the number of shares requested to be included. 
 No Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. If any Holder disapproves of the terms of any such
underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter. The Registrable Securities and/or other securities so withdrawn from such underwriting shall also be withdrawn from such registration;
provided, however, that, if by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the
underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities pursuant to the terms and limitations set forth herein in the same
proportion used above in determining the underwriter limitation. 
 (d) Other Registrations. Prior to the SEC Effective
Date the Company will not, without the prior written consent of the Majority Holders, file or request the acceleration of any other registration statement filed with the Commission, and during any time subsequent to the SEC Effective Date when the
Registration Statement for any reason is not available for use by any Holder for the resale of any Registrable Securities, the Company shall not, without the prior written consent of the Majority Holders, file any other registration statement or any
amendment thereto with the Commission under the Securities Act or request the acceleration of the effectiveness of any other registration statement previously filed with the Commission, other than (A) any registration statement on Form S-8
or Form S-4 and (B) any registration statement or amendment which the Company is required to file or as to which the Company is required to request acceleration pursuant to any obligation in effect on the date of execution and delivery of
this Agreement. 
 4. Registration Procedures. In the case of each registration, qualification, or compliance effected by
the Company pursuant to Section 3 hereof, the Company will keep each Holder including securities therein reasonably advised in writing (which may include e-mail) as to the initiation of each registration, qualification, and compliance and as to
the completion thereof. At its expense with respect to any registration statement filed pursuant to Section 3, the Company will use its commercially reasonable efforts to: 
 (a) prepare and file with the Commission with respect to such Registrable Securities, a registration statement on Form S-1 or any other
form for which the Company then qualifies or which counsel for the Company shall deem appropriate, and which form shall be available for the sale of the Registrable Securities in

  

 4 

 
accordance with the intended method(s) of distribution thereof, and use its commercially reasonable efforts to cause such registration statement to become and remain effective at least for a
period ending with the first to occur of (i) the sale of all Registrable Securities covered by the registration statement, and (ii) the availability under Rule 144 for the Holder to immediately, freely resell without restriction all
Registrable Securities covered by the registration statement (in either case, the “Effectiveness Period”); provided that no later than two business days before filing with the Commission a registration statement or prospectus
or any amendments or supplements thereto, the Company shall (i) furnish to one special counsel (“Holders’ Counsel”) selected by the Majority Holders for the benefit of the Holders, copies of all such documents
proposed to be filed (excluding any exhibits other than applicable underwriting documents), in substantially the form proposed to be filed, which documents shall be subject to the review of such Holders’ Counsel, and (ii) notify each
Holder of Registrable Securities covered by such registration statement of any stop order issued or threatened by the Commission and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered; 

(b) if a registration statement is subject to review by the Commission, promptly respond to all comments and diligently pursue resolution
of any comments to the satisfaction of the Commission; 
 (c) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective during the Effectiveness Period (but in any event at least until expiration of the 90-day
period referred to in Section 4(3) of the Securities Act and Rule 174, or any successor thereto, thereunder, if applicable), and comply with the provisions of the Securities Act with respect to the disposition of all securities
covered by such registration statement during such period in accordance with the intended method(s) of disposition by the sellers thereof set forth in such registration statement; 
 (d) furnish, without charge, to each Holder of Registrable Securities covered by such registration statement (i) a reasonable number of
copies of such registration statement (including any exhibits thereto other than exhibits incorporated by reference), each amendment and supplement thereto as such Holder may request, (ii) such number of copies of the prospectus included in
such registration statement (including each preliminary prospectus and any other prospectus filed under Rule 424 under the Securities Act) as such Holders may request, in conformity with the requirements of the Securities Act, and
(iii) such other documents as such Holder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holder, but only during the Effectiveness Period; 
 (e) use its commercially reasonable efforts to register or qualify such Registrable Securities under such other applicable securities or
blue sky laws of such jurisdictions as any Holder of Registrable Securities covered by such registration statement reasonably requests as may be necessary for the marketability of the Registrable Securities (such request to be made by the time the
applicable registration statement is deemed effective by the Commission) and do any and all other acts and things which may be reasonably necessary or advisable to enable such Holder to consummate the disposition in such jurisdictions of the
Registrable Securities owned by such Holder; provided that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph (e),
(ii) subject itself to taxation in any such jurisdiction, or (iii) consent to general service of process in any such jurisdiction; 
 (f) as promptly as practicable after becoming aware of such event, notify each Holder of such Registrable Securities at any time when a prospectus relating thereto is required to be delivered under the
Securities Act of the happening of any event which comes to the Company’s attention if as a result of such event the prospectus included in such registration statement contains an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements therein not misleading and the Company shall promptly prepare and furnish to such Holder a supplement or amendment to such prospectus (or prepare and file appropriate
reports under the Exchange Act) so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, unless suspension of the use of such prospectus otherwise is authorized herein or in the event of a Blackout Period, in which case no supplement or amendment need be furnished (or
Exchange Act filing made) until the termination of such suspension or Blackout Period; 
  

 5 

 (g) comply, and continue to comply during the period that such registration statement is
effective under the Securities Act, in all material respects with the Securities Act and the Exchange Act and with all applicable rules and regulations of the Commission with respect to the disposition of all securities covered by such
registration statement; 
 (h) as promptly as practicable after becoming aware of such event, notify each Holder of Registrable
Securities being offered or sold pursuant to the Registration Statement of the issuance by the Commission of any stop order or other suspension of effectiveness of the Registration Statement at the earliest possible time; 
 (i) permit the Holders of Registrable Securities being included in the Registration Statement and their legal counsel, at such Holders’
sole cost and expense (except as otherwise specifically provided in Section 6) to review and have a reasonable opportunity to comment on the Registration Statement and all amendments and supplements thereto at least two Business Days prior
to their filing with the Commission and shall not file any such document to which the Majority Holders reasonably object; 
 (j)
make available for inspection by any Holder and any Inspector retained by such Holder, at such Holder’s sole expense, all Records as shall be reasonably necessary to enable such Holder to exercise its due diligence responsibility, and cause the
Company’s officers, directors, and employees to supply all information which such Holder or any Inspector may reasonably request for purposes of such due diligence; provided, however, that such Holder shall hold in confidence and shall not make
any disclosure of any record or other information which the Company determines in good faith to be confidential, and of which determination such Holder is so notified at the time such Holder receives such information, unless (i) the disclosure
of such record is necessary to avoid or correct a misstatement or omission in the Registration Statement and a reasonable time prior to such disclosure the Holder shall have informed the Company of the need to so correct such misstatement or
omission and the Company shall have failed to correct such misstatement of omission, (ii) the release of such record is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction or (iii) the
information in such record has been made generally available to the public other than by disclosure in violation of this or any other agreement. The Company shall not be required to disclose any confidential information in such records to any
Inspector until and unless such Inspector shall have entered into a confidentiality agreement with the Company with respect thereto, substantially in the form of this Section 4(j), which agreement shall permit such Inspector to disclose records
to the Holder who has retained such Inspector. Each Holder agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to
the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the records deemed confidential. The Company shall hold in confidence and shall not make
any disclosure of information concerning a Holder provided to the Company pursuant to this Agreement unless (i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) disclosure of such
information to the Staff of the Division of Corporation Finance is necessary to respond to comments raised by the Staff in its review of the Registration Statement, (iii) disclosure of such information is necessary to avoid or correct a
misstatement or omission in the Registration Statement, (iv) release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction, or (v) such information has been made
generally available to the public other than by disclosure in violation of this or any other agreement. The Company agrees that it shall, upon learning that disclosure of such information concerning a Holder is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt notice to such Holder and allow such Holder, at such Holder’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order
for, such information; 
 (k) use its commercially reasonable efforts to cause all the Registrable Securities covered by the
Registration Statement to be quoted on the principal securities market on which securities of the same class or series issued by the Company are then listed or traded; 
 (l) provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities at all times; 
  

 6 

 (m) cooperate with the Holders of Registrable Securities being offered pursuant to the
Registration Statement to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities sold pursuant to the Registration Statement and enable such certificates to be in such
denominations or amounts as the Holders may reasonably request and registered in such names as the Holders may request; 
 (n)
during the Effectiveness Period, refrain from bidding for or purchasing any Common Stock or any right to purchase Common Stock or attempting to induce any Person to purchase any such security or right if such bid, purchase or attempt would in any
way limit the right of the Holders to sell Registrable Securities by reason of the limitations set forth in Regulation M under the 1934 Act; and 
 (o) take all other reasonable actions necessary to expedite and facilitate disposition by the Holders of the Registrable Securities pursuant to the Registration Statement. 
 5. Suspension of Offers and Sales. Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company of
the happening of any event of the kind described in Section 4(f) hereof or of the commencement of a Blackout Period, such Holder shall discontinue disposition of Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 4(f) hereof or notice of the end of the Blackout Period, and, if so directed by the Company, such
Holder shall deliver to the Company (at the Company’s expense) all copies (including, without limitation, any and all drafts), other than permanent file copies, then in such Holder’s possession, of the prospectus covering such Registrable
Securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the period mentioned in Section 4(a)(iii) hereof shall be extended by the greater of (i) ten business days or (ii) the
number of days during the period from and including the date of the giving of such notice pursuant to Section 4(f) hereof to and including the date when each Holder of Registrable Securities covered by such registration statement shall
have received the copies of the supplemented or amended prospectus contemplated by Section 4(f) hereof. 
 6.
Registration Expenses. The Company shall pay all expenses in connection with any registration, including, without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with securities
or blue sky laws, the fees and disbursements of counsel for the Company and of its independent accountants, and the reasonable fees and disbursements of a Holders’ Counsel (not to exceed $10,000); provided that, in any underwritten
registration, each party shall pay for its own underwriting discounts and commissions and transfer taxes. Except as provided above in this Section 6 and Section 9, the Company shall not be responsible for the expenses of any attorney or
other advisor employed by a Holder of Registrable Securities. 
 7. Assignment of Rights. No Holder may assign its rights
under this Agreement to any party without the prior written consent of the Company; provided, however, that a Holder may assign its rights under this Agreement without such restrictions to a Permitted Assignee as long as (a) such
transfer or assignment is effected in accordance with applicable securities laws; (b) such transferee or assignee agrees in writing to become subject to the terms of this Agreement; and (c) the Company is given written notice by such
Holder of such transfer or assignment, stating the name and address of the transferee or assignee and identifying the Registrable Securities with respect to which such rights are being transferred or assigned. 
 8. Information by Holder. The Holder or Holders of Registrable Securities included in any registration shall furnish to the Company
such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as the Company may request in writing. 
 9. Indemnification. 
 (a) In the event of the offer and sale of Registrable
Securities held by Holders under the Securities Act, the Company shall, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, partners, and each other person, if any, who controls
or is under common control with such Holder or any such underwriter within the meaning of Section 15 of the Securities Act, against any

  

 7 

 
losses, claims, damages or liabilities, joint or several, and expenses to which the Holder or any such director, officer, partner or underwriter or controlling person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under which such shares were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein in light of the circumstances in which they were made not misleading, and the Company
shall reimburse the Holder, and each such director, officer, partner, and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating, defending or settling any such loss, claim, damage,
liability, action or proceeding; provided that the Company shall not be liable in any such case (i) to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based
upon an untrue statement or alleged untrue statement in or omission or alleged omission from such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by or on behalf of such Holder or (ii) if the person asserting any such loss, claim, damage, liability (or action or proceeding in respect thereof) who purchased the Registrable
Securities that are the subject thereof did not receive a copy of an amended preliminary prospectus or the final prospectus (or the final prospectus as amended or supplemented) at or prior to the written confirmation of the sale of such Registrable
Securities to such person because of the failure of such Holder or underwriter to so provide such amended preliminary or final prospectus and the untrue statement or alleged untrue statement or omission or alleged omission of a material fact made in
such preliminary prospectus was corrected in the amended preliminary or final prospectus (or the final prospectus as amended or supplemented). Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf
of the Holders, or any such director, officer, partner, underwriter or controlling person and shall survive the transfer of such shares by the Holder. 
 (b) As a condition to including any Registrable Securities to be offered by a Holder in any registration statement filed pursuant to this Agreement, each such Holder agrees to be bound by the terms of
this Section 9 and to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities
Act, against any losses, claims, damages or liabilities, joint or several, to which the Company or any such director or officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement in or omission or alleged omission from such registration statement, any
preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written
information about such Holder as a Holder of the Company furnished to the Company, and such Holder shall reimburse the Company, and each such director, officer, and controlling person for any legal or other expenses reasonably incurred by them in
connection with investigating, defending, or settling any such loss, claim, damage, liability, action, or proceeding; provided, however, that such indemnity agreement found in this Section 9(b) shall in no event exceed the
gross proceeds from the offering received by such Holder. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling person and shall survive
the transfer by any Holder of such shares. 
 (c) Promptly after receipt by an indemnified party of notice of the commencement
of any action or proceeding involving a claim referred to in Section 9(a) or (b) hereof (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give
written notice to the indemnifying party of the commencement of such action; provided that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under
Section 9(a) or (b) hereof, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in the reasonable judgment of
counsel to such indemnified party a conflict of interest between such indemnified and indemnifying parties may exist or the indemnified party may have defenses not available to the indemnifying party in respect of such claim, the indemnifying party
shall be entitled to participate in and to assume the defense thereof, with counsel reasonably

  

 8 

 
satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not
be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof, unless in such indemnified party’s reasonable judgment a conflict of interest between such
indemnified and indemnifying parties arises in respect of such claim after the assumption of the defenses thereof or the indemnifying party fails to defend such claim in a diligent manner, other than reasonable costs of investigation. Neither an
indemnified nor an indemnifying party shall be liable for any settlement of any action or proceeding effected without its consent. No indemnifying party shall, without the consent of the 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 of such claim or litigation. Notwithstanding anything to the
contrary set forth herein, and without limiting any of the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to the defense of a claim. 
 (d) In the event that an indemnifying party does not or is not permitted to assume the defense of an action pursuant to
Section 9(c) or in the case of the expense reimbursement obligation set forth in Section 9(a) and (b), the indemnification required by Section 9(a) and (b) hereof shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as and when bills received or expenses, losses, damages, or liabilities are incurred. 
 (e) If the indemnification provided for in this Section 9 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or
expense referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall (i) contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or
expense as is appropriate to reflect the proportionate relative fault of the indemnifying party on the one hand and the indemnified party on the other (determined by reference to, among other things, whether the untrue or alleged untrue statement of
a material fact or omission relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or
omission), or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, not only the proportionate relative fault of the
indemnifying party and the indemnified party, but also the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other, as well as any other relevant equitable considerations. No indemnified party
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation. 
 (f) Other Indemnification. Indemnification similar to that specified in the preceding subsections of this Section 9 (with
appropriate modifications) shall be given by the Company and each Holder of Registrable Securities with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority
other than the Securities Act. 
 10. Miscellaneous. 
 (a) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Oregon and the United
States of America, both substantive and remedial. Any judicial proceeding brought against either of the parties to this agreement or any dispute arising out of this Agreement or any matter related hereto may be brought in the courts of the State of
Oregon or in the United States District Court for the District of Oregon and, by its execution and delivery of this agreement, each party to this Agreement accepts the jurisdiction of such courts. The foregoing consent to jurisdiction shall not be

 A - 2First Amendment and Consent, dated December 18, 2009

 Exhibit 10.1 
 EXECUTION VERSION 
 FIRST AMENDMENT AND CONSENT

 This First Amendment and Consent (the “Amendment”) to each of the Credit Agreement and Collateral Agreement
referred to below is dated as of December 18, 2009, by and among MANTECH INTERNATIONAL CORPORATION, a Delaware corporation, in its capacity as Borrower under the Credit Agreement referred to below (the “Borrower”), certain
subsidiaries of the Borrower party hereto (the “Subsidiary Grantors”), the Lenders party hereto (the “Consenting Lenders”) pursuant to an authorization (in the form attached hereto as Exhibit A, each a
“Lender Authorization”), and BANK OF AMERICA, N.A., as administrative agent (the “Administrative Agent”) for the Lenders party to the Credit Agreement referred to below. 
 STATEMENT OF PURPOSE: 
 The Borrower, the Lenders, certain other financial institutions and the Administrative Agent are parties to the Credit Agreement dated as of April 30, 2007 (as amended, restated, supplemented or otherwise modified prior to the date
hereof, the “Credit Agreement”). 
 The Borrower and certain of its Subsidiaries, as grantors, and the
Administrative Agent, as collateral agent, are parties to the Collateral Agreement dated as of April 30, 2007 (as amended, restated, supplemented or otherwise modified prior to the date hereof, the “Collateral Agreement”).

 The Borrower has requested that the Administrative Agent and the Lenders agree to amend the Credit Agreement and the
Collateral Agreement, each as more specifically set forth herein. Subject to the terms and conditions set forth herein, the Administrative Agent and each of the Consenting Lenders have agreed to grant such requests of the Borrower. 
 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby
agree as follows: 
 1. Capitalized Terms. All capitalized terms not otherwise defined herein (including, without
limitation, in the introductory paragraph and the statement of purpose hereto) shall have the meanings assigned thereto in the Credit Agreement (as amended by this Amendment) or the Collateral Agreement (as amended by this Amendment), as applicable.

 2. Credit Agreement Amendments. The Credit Agreement is hereby modified as follows: 
 (a) New Definitions. The following definitions are hereby added to Section 1.01 in proper alphabetical
order to read in their respective entirety as follows: 
 “‘Eurodollar Unavailability
Period’ means any period of time during which a notice delivered to the Borrower in accordance with Section 3.02 or Section 3.03 shall remain in effect.” 
 “‘Prime Rate’ means the rate of interest in effect for such day as publicly announced from time to time
by Bank of America as its “prime rate.” The “prime rate” is a rate set by Bank of America based upon various factors including Bank of America’s costs and desired return, general economic conditions and other factors, and is
used as a reference point for pricing some loans, which may be priced at, above, or below such announced rate. Any change in such rate announced by Bank of America shall take effect at the opening of business on the day specified in the public
announcement of such change; provided, however, that with respect to Swing Line Loans only, at all times in which the Swing Line Lender is not Bank of America, each of the foregoing references to ‘Bank of America’ shall be deemed to be
references to the ‘Swing Line Lender’.” 

 “‘Transaction Costs’ means all transaction fees,
charges and other amounts related to acquisitions permitted pursuant to Section 7.03(h) (whether or not consummated) and other extraordinary, non-recurring and unusual costs or losses incurred following the Closing Date.”

 (b) Amended Definitions. The following definitions set forth in Section 1.01 are hereby
amended as follows: 
 (i) The definition of “Applicable Rate” is hereby amended and restated to read
in its entirety as follows: 
 “‘Applicable Rate’ means, the following percentages per annum, based upon
the Consolidated Leverage Ratio as set forth in the most recent Compliance Certificate received by the Administrative Agent pursuant to Section 6.02(b): 
  

									
	 Level
	  	 Consolidated Leverage Ratio
	  	Commitment
Fee	 	Applicable Rate for
Eurodollar Rate Loans	 	Applicable Rate for
Base Rate Loans
	  	  	 	Applicable Rate for
Letters of Credit	 
	I	  	Less than 1.50 to 1.00	  	0.200%	 	1.625%	 	0.750%
	II	  	Greater than or equal to 1.50 to 1.00 but less than 2.00 to 1.00	  	0.225%	 	1.750%	 	0.750%
	III	  	Greater than or equal to 2.00 to 1.00 but less than 2.50 to 1.00	  	0.250%	 	1.875%	 	0.750%
	IV	  	Greater than or equal to 2.50 to 1.00 but less than 3.00 to 1.00	  	0.275%	 	2.250%	 	1.250%
	V	  	Greater than or equal to 3.00 to 1.00	  	0.300%	 	2.500%	 	1.500%

 Any increase or decrease in the Applicable Rate resulting from a
change in the Consolidated Leverage Ratio shall become effective as of the first Business Day immediately following the date a Compliance Certificate is delivered pursuant to Section 6.02(b); provided, however, that if a
Compliance Certificate is not delivered when due in accordance with such Section, then Pricing Level V shall apply as of the first Business Day after the date on which such Compliance Certificate was required to have been delivered until such time
as the Compliance Certificate is in fact delivered. 
 (ii) The definition of “Base Rate” is hereby
amended and restated to read in its entirety as follows: 
 “‘Base Rate’ means, for any day, a rate per
annum equal to the highest for such day of (a) the Prime Rate, (b) the sum of 0.50% plus the Federal Funds Rate and (c) except during a Eurodollar Unavailability Period, 1.00% plus the Eurodollar Rate.” 
  

 2 

 (iii) The definition of “Business Day” is hereby amended and
restated to read in its entirety as follows: 
 “‘Business Day’ means any day other than a Saturday,
Sunday or other day on which commercial banks are authorized to close under the Laws of, or are in fact closed in, the state where the Administrative Agent’s Office is located and, if such day related to any determination of the Eurodollar
Rate, means any such day on which dealings in Dollar deposits are conducted by and between banks in the London interbank Eurodollar market and with respect to any Letters of Credit issued in an Alternative Currency, any such day on which banks are
open for foreign exchange business in the principal financial center of the country of such currency.” 
 (iv) The definition of “Consolidated EBITDA” is hereby amended by adding the following new clause (vi) to the end of clause (a) of such definition: 
 “and (vi) Transaction Costs actually incurred (up to an aggregate amount equal to $5,000,000 in any four (4) fiscal quarter
period)” 
 (v) The definition of “Consolidated Fixed Charges” is hereby amended by amending and
restating clause (e) of such definition as follows: 
 “(e) cash repurchases of the Equity Interests of the Borrower
or any of its Subsidiaries from Persons that are not Loan Parties (including, without limitation, Restricted Payments made pursuant to Section 7.06) during such period.” 
 (vi) The definition of “Equity Interests” is hereby amended by adding the following proviso at the end thereof:

 “provided that prior to any conversion of convertible debt incurred pursuant to Section 7.02(k) into
equity securities or capital stock, such convertible debt incurred pursuant to Section 7.02(k) shall not constitute Equity Interests.” 
 (vii) The definition of “Eurodollar Rate” is hereby amended and restated to read in its entirety as follows: 
 “‘Eurodollar Rate’ means, 
 (a) for any Interest Period with
respect to a Eurodollar Rate Loan, the rate per annum equal to (i) the British Bankers Association LIBOR rate, as published by Reuters (or other commercially available source providing quotations of BBA LIBOR as designated by the Administrative
Agent from time to time) (‘BBA LIBOR’) at approximately 11:00 a.m., London time, two Business Days prior to the commencement of such Interest Period, for Dollar deposits (for delivery on the first day of such Interest Period) with a
term equivalent to such Interest Period or (ii) if such published rate is not available at such time for any reason, the rate determined by the Administrative Agent to be the rate at which deposits in Dollars for delivery on the first day of
such Interest Period in same day funds

  

 3 

 
in the approximate amount of the Eurodollar Rate Loan being made, continued or converted by Bank of America and with a term equivalent to such Interest Period would be offered by Bank of
America’s London Branch to major banks in the London interbank eurodollar market at their request at approximately 11:00 a.m. (London time) two Business Days prior to the commencement of such Interest Period, or 
 (b) for any interest rate calculation with respect to a Base Rate Loan, the rate per annum equal to (i) BBA LIBOR, at approximately
11:00 a.m., London time on the date of determination (provided that if such day is not a Business Day, the next preceding Business Day) for Dollar deposits being delivered in the London interbank market for a term of one month commencing that day or
(ii) if such published rate is not available at such time for any reason, the rate determined by the Administrative Agent to be the rate at which deposits in Dollars for delivery on the date of determination in same day funds in the approximate
amount of the Base Rate Loan being made, continued or converted by Bank of America and with a term equal to one month would be offered by Bank of America’s London Branch to major banks in the London interbank eurodollar market at their request
at the date and time of determination. 
 (c) Amendment to Section 2.14 “Increase in
Commitments”. Section 2.14 is hereby amended and restated to read in its entirety as follows: 
 “2.14 Increase in Commitments. 
 (a) Request for Increase. Provided there exists no
Default or Event of Default, upon notice to the Administrative Agent (which shall promptly notify the Lenders), the Borrower may from time to time, request an increase in the Aggregate Commitments by an amount (for all such requests) not exceeding
$50,000,000; provided that (i) any such request for an increase shall be in a minimum amount of $10,000,000, (ii) the Borrower may make a maximum of one such requests and (iii) no increases may be requested after
February 26, 2010 without the prior written consent of the Administrative Agent. At the time of sending such notice, the Borrower (in consultation with the Administrative Agent) shall specify the time period within which each Lender is
requested to respond (which shall in no event be less than four (4) Business Days from the date of delivery of such notice to the Lenders). 
 (b) Lender Elections to Increase. Each Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its Commitment and, if so, whether by an amount
equal to, greater than, or less than its Applicable Percentage of such requested increase. Any Lender not responding within such time period shall be deemed to have declined to increase its Commitment. 
 (c) Notification by Administrative Agent; Additional Lenders. The Administrative Agent shall notify the Borrower and
each Lender of the Lenders’ responses to each request made hereunder. Subject to the approval of the Administrative Agent, the L/C Issuer and the Swing Line Lender (which approvals shall not be unreasonably withheld), the Borrower may also
invite additional Eligible Assignees to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel. 
 (d) Effective Date and Allocations. If the Aggregate Commitments are increased in accordance with this Section, the
Administrative Agent and the Borrower shall determine the

  

 4 

 
effective date (the “Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final
allocation of such increase and the Increase Effective Date. 
 (e) Conditions to Effectiveness of
Increase. As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent a certificate of each Loan Party dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible
Officer of such Loan Party (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such
increase, (A) the representations and warranties contained in Article V and the other Loan Documents are true and correct on and as of the Increase Effective Date, except to the extent that such representations and warranties
specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.14, the representations and warranties contained in subsections (a) and
(b) of Section 5.05 shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01, and (B) no Default exists and shall be continuing. The
Borrower shall prepay any Committed Loans outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 3.05) to the extent necessary to keep the outstanding Committed Loans ratable with any
revised Applicable Percentages arising from any nonratable increase in the Commitments under this Section. 
 (f)
Conflicting Provisions. This Section shall supersede any provisions in Section 2.13 or 10.01 to the contrary.” 
 (d) Amendment to Section 3.02 “Illegality”. Section 3.02 is hereby amended and restated to read in its entirety as follows: 
 “3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority
has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate, or any Governmental Authority has imposed
material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of
such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Committed Loans to Eurodollar Rate Loans or, if such notice relates to the unlawfulness or asserted unlawfulness of charging interest based on the Eurodollar Rate, to make
Base Rate Loans as to which the interest rate is determined with reference to the Eurodollar Rate shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no
longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender and Base Rate Loans as to which
the interest rate is determined with reference to the Eurodollar Rate to Base Rate Loans as to which the rate of interest is not determined with reference to the Eurodollar Rate, either on the last day of the Interest Period therefor, if such Lender
may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans or a Base Rate Loan as to which the interest rate is determined with reference
to the Eurodollar Rate. Notwithstanding the foregoing and despite the illegality for such a Lender to make, maintain or fund Eurodollar Rate Loans or Base Rate Loans as to which the interest rate is determined with reference to the

  

 5 

 
Eurodollar Rate, that Lender shall remain committed to make Base Rate Loans as to which the rate of interest is not determined with reference to the Eurodollar Rate and shall be entitled to
recover interest at such Base Rate. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted.” 
 (e) Amendment to Section 3.03 “Inability to Determine Rates”. Section 3.03 is hereby
amended and restated to read in its entirety as follows: 
 “3.03 Inability to Determine Rates. If
the Required Lenders determine that for any reason in connection with any request for a Eurodollar Rate Loan or a Base Rate Loan as to which the interest rate is determined with reference to the Eurodollar Rate or a conversion to or continuation
thereof that (a) Dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and Interest Period of such Loan, (b) adequate and reasonable means do not exist for determining the
Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan or in connection with a Base Rate Loan, or (c) the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate
Loan or in connection with a Eurodollar Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, the Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, the obligation of
the Lenders to make or maintain Eurodollar Rate Loans and Base Rate Loans as to which the interest rate is determined with reference to the Eurodollar Rate shall be suspended until the Administrative Agent (upon the instruction of the Required
Lenders) revokes such notice and during such period Base Rate Loans shall be made and continued based on the interest rate determined by the greater of clauses (a) and (b) in the definition of Base Rate. Upon receipt of such notice,
the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Committed Borrowing of Base Rate Loans in the
amount specified therein.” 
 (f) Amendment to Section 5.03 “Governmental Authorization; Other
Consents”. Section 5.03(c) is hereby amended by adding the following parenthetical at the end of such clause “other than the filing of Uniform Commercial Code financing statements with the appropriate Governmental
Authorities”. 
 (g) Amendment to Section 5.13 “Subsidiaries; Equity Interests”.
Section 5.13 is hereby amended by replacing the parenthetical “(other than Liens permitted pursuant to Section 7.01(a))” in such Section with “(other than Liens permitted pursuant to Sections 7.01(a),
7.01(c) or 7.01(h))”. 
 (h) Amendment to Article VI “Affirmative Covenants”.
The introductory paragraph of Article VI is hereby amended and restated to read in its entirety as follows: 
 “So long as any Lender shall have any Commitment hereunder, any Loan or other Obligation (other than contingent indemnification obligations to the extent no claim arising thereunder has been asserted) hereunder shall remain unpaid or
unsatisfied, or any Letter of Credit shall remain outstanding, the Borrower shall, and shall (except in the case of the covenants set forth in Sections 6.01, 6.02, 6.03 and 6.11) cause each Subsidiary to:”

 (i) Amendment to Section 6.04 “Payment of Obligations”. Section 6.04(b) is
hereby amended by adding the following clause at the end of such subsection, “unless the same are being

  

 6 

 
contested in good faith by appropriate proceedings diligently conducted and adequate reserves in accordance with GAAP are being maintained by the Borrower or such Subsidiary”. 
 (j) Amendment to Section 6.12 “Additional Guarantors”. Section 6.12(a) is hereby amended
and restated to read in its entirety as follows: 
 “(a) Notify the Administrative Agent within fifteen
(15) days after any Person becomes a Subsidiary, and promptly thereafter (and in any event within sixty (60) days after such notification is received by the Administrative Agent), cause such Person (other than any such Person that is a
CFC) to (i) become a Guarantor by executing and delivering to the Administrative Agent a counterpart of the Guaranty or such other document as the Administrative Agent shall deem appropriate for such purpose, (ii) execute and deliver to
the Administrative Agent a joinder to the Collateral Agreement and (iii) deliver to the Administrative Agent documents of the types referred to in clauses (iii) and (iv) of Section 4.01(a) and, to the extent requested by
the Administrative Agent, favorable opinions of counsel to such Person (which shall cover, among other things, the legality, validity, binding effect and enforceability of the documentation referred to in clause (a)), all in form, content and scope
reasonably satisfactory to the Administrative Agent.” 
 (k) Amendment to Section 6.16 “Deposit
Accounts”. Section 6.16 is hereby amended by deleting the words “Excluded Account” and substituting in lieu thereof the words “Excluded Deposit Account”. 
 (l) Amendment to Article VII “Negative Covenants”. The introductory paragraph of Article VII is hereby
amended and restated to read in its entirety as follows:
