WHEREAS, at the request of the Company, Indemnitee will serve or currently serves as [a director] [and] [an officer] of the Company and may, therefore, be subjected to claims, suits or proceedings arising as a result of such service; and
WHEREAS, as an inducement to Indemnitee to serve or continue to serve in such capacity, the Company has agreed to indemnify and to advance expenses and costs incurred by Indemnitee in connection with any such claims, suits or proceedings, to the maximum extent permitted by law; and
WHEREAS, the parties to this Agreement desire to set forth their agreement regarding indemnification and advance of expenses and to supersede any prior agreement to which the Company and Indemnitee are parties regarding the same; provided that this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the charter or Bylaws of the Company, any agreement entered into after the date hereof or a resolution of the stockholders entitled to vote generally in the election of directors or of the Board of Directors, or otherwise. 
NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows:
Section 1.Definitions.  For purposes of this Agreement:
(a)
    “Change in Control” means a change in control of the Company occurring after the Effective Date of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), whether or not the Company is then subject to such reporting requirement; provided, however, that, without limitation, such a Change in Control shall be deemed to have occurred if, after the Effective Date (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 15% or more of the combined voting power of all of the Company’s then-outstanding securities entitled to vote generally in the election of directors without the prior approval of at least two-thirds of the Incumbent Board; (ii) the Company is a party to a merger, consolidation, sale of assets, plan of liquidation or other reorganization not approved by at least two-thirds of the Incumbent Board, as a consequence of which members of the Board of Directors in office immediately prior to such transaction or event constitute less than a majority of the Board of Directors thereafter; or (iii) at any time, a majority of the members of the Board of Directors are not individuals from the Incumbent Board.
(b)
    “Corporate Status” means the status of a person as a present or former director, officer, employee or agent of the Company or as a director, trustee, officer, partner, manager, managing member, fiduciary, employee or agent of any other foreign or domestic corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving in such capacity at the request of the Company.  As a clarification and without limiting the circumstances in which Indemnitee may be serving at the request of the Company, service by Indemnitee shall be deemed to be at the request of the Company:  (i) if Indemnitee serves or served as a director, trustee, officer, partner, manager, managing member, fiduciary, employee or agent of any corporation, partnership, limited liability company, joint venture, trust or other enterprise (1) of which a majority of the voting power or equity interest is or was owned directly or indirectly by the Company or (2) the management of which is controlled directly or indirectly by the Company, and (ii) if, as a result of Indemnitee’s service to the Company or any of its affiliated entities, Indemnitee is subject to duties by, or required to perform services for, an employee benefit plan or its participants or beneficiaries, including as a deemed fiduciary thereof.

If Indemnitee reasonably believes that a given situation may lead to or culminate in the institution of a Proceeding, such situation shall also be considered a Proceeding.
Section 2.
    Services by Indemnitee.  Indemnitee will serve in the capacity or capacities setforth in the first WHEREAS clause above.  However, this Agreement shall not impose any independent obligation on Indemnitee or the Company to continue Indemnitee’s service to the Company.  This Agreement shall not be deemed an employment contract between the Company (or any other entity) and Indemnitee.
Section 3.
    General.  The Company shall indemnify, and advance Expenses to, Indemnitee (a) as provided in this Agreement and (b) otherwise to the maximum extent permitted by Maryland law in effect on the Effective Date and as amended from time to time; provided, however, that no change in Maryland law shall have the effect of reducing the benefits available to Indemnitee hereunder based on Maryland law as in effect on the Effective Date.  The rights of Indemnitee provided in this Section 3 shall include, without limitation, the rights set forth in the other sections of this Agreement, including any additional indemnification permitted by the Maryland General Corporation Law (the “MGCL”), including, without limitation, Section 2-418 of the MGCL.
Section 4.
    Standard for Indemnification.  If, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be, made a party to any Proceeding, the Company shall indemnify and hold harmless Indemnitee against all judgments, penalties, fines and amounts paid in settlement and all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with any such Proceeding or any action, discovery event, claim, issue or matter therein or related thereto unless it is established that (a) the act or omission of Indemnitee was material to the matter giving rise to the Proceeding and (i) was committed in bad faith or (ii) was the result of active and deliberate dishonesty, (b) Indemnitee actually received an improper personal benefit in money, property or services or (c) in the case of any criminal Proceeding, Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.
Section 5.
    Certain Limits on Indemnification.  Notwithstanding any other provision of this Agreement (other than Section 6) and except to the extent otherwise permitted by Maryland law, Indemnitee shall not be entitled to:
(a)
    indemnification hereunder if the Proceeding was one by or in the right of the Company and Indemnitee is adjudged, in a final adjudication of the Proceeding not subject to further appeal, to be liable to the Company; 
(b)
    indemnification hereunder if Indemnitee is adjudged, in a final adjudication of the Proceeding not subject to further appeal, to be liable on the basis that personal benefit was improperly received in any Proceeding charging improper personal benefit to Indemnitee, whether or not involving action in Indemnitee’s Corporate Status; or
(c)
    indemnification or advance of Expenses hereunder if the Proceeding was brought by Indemnitee, unless: (i) the Proceeding was brought to enforce indemnification under this Agreement, and then only to the extent in accordance with and as authorized by Section 12 of this Agreement, or (ii) the Company’s charter or Bylaws, a resolution of the stockholders entitled to vote generally in the election of directors or of the Board of Directors or an agreement approved by the Board of Directors to which the Company is a party expressly provide otherwise.
Section 6.
    Court-Ordered Indemnification.  Notwithstanding any other provision of this Agreement, a court of appropriate jurisdiction, upon application of Indemnitee and such notice as the court shall require, may order indemnification of Indemnitee by the Company in the following circumstances:
(a)
    if such court determines that Indemnitee is entitled to reimbursement under Section 2-418(d)(1) of the MGCL, the court shall order indemnification, in which case Indemnitee shall be entitled to recover the Expenses of securing such reimbursement; or
(b)
    if such court determines that Indemnitee is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not Indemnitee (i) has met the standards of conduct set forth in Section 2-418(b) of the MGCL or (ii) has been adjudged liable for receipt of an improper personal benefit under Section 2-418(c) of the MGCL, the court may order such indemnification as the court shall deem proper without regard to any limitation on such court-ordered indemnification contemplated by Section 2-418(d)(2)(ii) of the MGCL.
Section 7.
    Indemnification of an Indemnitee Who is Wholly or Partially Successful.  Notwithstanding any other provision of this Agreement, and without limiting any such provision, to the extent that Indemnitee was or is, by reason of Indemnitee’s Corporate Status, made a party to (or otherwise becomes a participant in) any Proceeding and is successful, on the merits or otherwise, in the defense of such Proceeding, the Company shall indemnify Indemnitee for all Expenses, judgments, penalties and/or amounts paid in settlement that are actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith.  If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee under this Section 7 for all Expenses, judgments, penalties and/or amounts paid in settlement that are actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each such claim, issue or matter as to which Indemnitee is entitled to indemnification.  For purposes of this Section 7 and, without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, and a decision by any government, regulatory or self-regulatory authority, agency or body not to commence or pursue any investigation, civil or criminal enforcement matter or case or any civil suit shall be deemed to be a successful result as to such claim, issue or matter.
Section 8.
    Advance of Expenses for Indemnitee.  If, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be, made a party to any Proceeding, the Company shall, without requiring a preliminary determination of Indemnitee’s ultimate entitlement to indemnification hereunder, advance all Expenses incurred by or on behalf of Indemnitee in connection with such Proceeding, including any Proceeding commenced pursuant to Section 12 of this Agreement.  The Company shall make such advance or advances within ten days after the receipt by the Company of a statement or statements requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding and may be in the form of, in the reasonable discretion of Indemnitee (but without duplication) (a) payment of such Expenses directly to third parties on behalf of Indemnitee, (b) advance of funds to Indemnitee in an amount sufficient to pay such Expenses or (c) reimbursement to Indemnitee for Indemnitee’s payment of such Expenses.  Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee (provided, however, that following a Change in Control or in the event of a Proceeding brought by or in the name of the Company, Indemnitee shall be required to submit to the Company only summary statements and invoices and, in connection with such submissions, Indemnitee shall have the right to withhold or redact any documents or information that are protected by the attorney-client privilege or the attorney work product doctrine) and shall include or be preceded or accompanied by a written affirmation by Indemnitee and a written undertaking by or on behalf of Indemnitee, in substantially the form attached hereto as Exhibit A or in such form as may be required under applicable law as in effect at the time of the execution thereof.  To the extent that Expenses advanced to Indemnitee do not relate to a specific claim, issue or matter in the Proceeding, such Expenses shall be allocated on a reasonable and proportionate basis.  The undertaking required by this Section 8 shall be an unlimited general obligation by or on behalf of Indemnitee, shall be interest free and shall be accepted without reference to Indemnitee’s financial ability to repay such advanced Expenses and without any requirement to post security therefor.
Section 9.
    Indemnification and Advance of Expenses as a Witness or Other Participant.  Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is or may be, by reason of Indemnitee’s Corporate Status, made a witness or otherwise asked to participate in any Proceeding, whether instituted by the Company or any other party, and to which Indemnitee is not a party, Indemnitee shall be advanced and indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith within ten days after the receipt by the Company of a statement or statements requesting any such advance or indemnification from time to time, whether prior to or after final disposition of such Proceeding.  Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee.  In connection with any such advance of Expenses, the Company may require Indemnitee to provide an undertaking and affirmation substantially in the form attached hereto as Exhibit A.
Section 10.
    Procedure for Determination of Entitlement to Indemnification.
(a)
    To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification; provided that the failure of Indemnitee to so notify the Company will not relieve the Company from any liability that it may have to Indemnitee under this Agreement or otherwise to the extent the failure or delay does not materially prejudice the Company.  Indemnitee may submit one or more such requests from time to time and at such time(s) as Indemnitee deems appropriate in Indemnitee’s sole discretion.  The officer of the Company receiving any such request from Indemnitee shall, promptly upon receipt of such a request for indemnification, advise the Board of Directors in writing that Indemnitee has requested indemnification.
(b)
    Upon written request by Indemnitee for indemnification pursuant to Section 10(a) above, a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall promptly be made in the specific case: (i) if a Change in Control has occurred, by Independent Counsel, in a written opinion to the Board of Directors, a copy of which shall be delivered to Indemnitee, which Independent Counsel shall be selected by Indemnitee and approved by the Board of Directors in accordance with Section 2-418(e)(2)(ii) of the MGCL, which approval shall not be unreasonably withheld; or (ii) if a Change in Control has not occurred, (A) by a majority vote of the Disinterested Directors or, by the majority vote of a group of Disinterested Directors designated by the Disinterested Directors to make the determination, (B) if Independent Counsel has been selected by the Board of Directors in accordance with Section 2-418(e)(2)(ii) of the MGCL and approved by Indemnitee, which approval shall not be unreasonably withheld or delayed, by Independent Counsel, in a written opinion to the Board of Directors, a copy of which shall be delivered to Indemnitee or (C) if so directed by the Board of Directors, by the stockholders of the Company, provided, however, that shares held by directors or officers who are parties to the Proceeding shall not be voted.  If it is so determined that Indemnitee is entitled to indemnification, the Company shall make payment to Indemnitee within ten days after such determination.  Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary or appropriate to such determination in the discretion of the Board of Directors or Independent Counsel if retained pursuant to clause (ii)(B) of this Section 10(b).  Any Expenses incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company shall indemnify and hold Indemnitee harmless therefrom.
(c)
    The Company shall pay the reasonable fees and expenses of Independent Counsel, if one is appointed.
Section 11.
    Presumptions and Effect of Certain Proceedings.
(a)
    In making any determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 10(a) of this Agreement, and the Company shall have the burden of overcoming that presumption in connection with the making of any determination contrary to that presumption.  The failure of the person or persons or entity making any determination with respect to Indemnitee’s entitlement to indemnification hereunder to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper, or other rights are available, because Indemnitee has met the requisite standard of conduct, shall not be a defense to the action and shall not create a presumption regarding whether Indemnitee has met the requisite standard of conduct.
(b)
    The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, upon a plea of nolo contendere or its equivalent, or entry of an order of probation prior to judgment, does not create a presumption that Indemnitee did not meet the requisite standard of conduct described herein for indemnification.
(c)
    The knowledge and/or actions, or failure to act, of any other director, officer, employee or agent of the Company or any other director, trustee, officer, partner, manager, managing member, fiduciary, employee or agent of any other foreign or domestic corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise shall not be imputed to Indemnitee for purposes of determining any other right to indemnification under this Agreement.
(d)
    For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on any information, opinion, report or statement, including any financial statement or other financial data of the Company (or other applicable entity) prepared or presented by: (i) an officer or employee of the Company (or other applicable entity) whom Indemnitee reasonably believes to be reliable and competent in the matters presented, (ii) a lawyer, certified public accountant, or other person, as to a matter which Indemnitee reasonably believes to be within the person’s professional or expert competence or (iii) a committee of the Board of Directors on which Indemnitee does not serve, as to a matter with its designated authority, if Indemnitee reasonably believes the committee to merit confidence; provided, in each case, Indemnitee has no knowledge concerning the matter in question which would cause such reliance to be unwarranted. The provisions of this Section 11(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed or found to have met the requisite standard of conduct described herein for indemnification.
Section 12.
    Remedies of Indemnitee.
(a)
    If (i) a determination is made pursuant to Section 10(b) of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advance of Expenses is not timely made pursuant to Sections 8 or 9 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 10(b) of this Agreement within 60 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Sections 7 or 9 of this Agreement within ten days after receipt by the Company of a written request therefor, or (v) payment of indemnification pursuant to any other section of this Agreement or the charter or Bylaws of the Company is not made within ten days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to an adjudication in an appropriate court located in the State of Maryland, or in any other court of competent jurisdiction, or arbitration, conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association, of Indemnitee’s entitlement to indemnification or advance of Expenses.  The judicial proceeding or arbitration commenced pursuant to this Section shall be conducted in all respects as a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of a prior adverse determination.  Indemnitee shall commence a proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 12(a); provided, however, that the foregoing clause shall not apply to a proceeding brought by Indemnitee to enforce Indemnitee’s rights under Section 7 of this Agreement.  Except as set forth herein, the provisions of Maryland law (without regard to its conflicts of laws rules) shall apply to any such arbitration. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. If Indemnitee seeks an adjudication in a court located in the State of Maryland, the parties agree to request that the action be assigned to the business and technology case management program of the circuit in which the action is filed.
(b)
    In any judicial proceeding or arbitration commenced pursuant to this Section 12, or otherwise arising out of this Agreement, Indemnitee shall be presumed to be entitled to indemnification or advance of Expenses, as the case may be, under this Agreement and the Company shall have the burden of proving that Indemnitee is not entitled to indemnification or advance of Expenses, as the case may be.  If Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 12, or otherwise arising out of this Agreement, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 8 of this Agreement until a final determination is made with respect to Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed).  The Company shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all of the provisions of this Agreement.
(c)
    If a determination shall have been made pursuant to Section 10(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 12, absent a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification that was not introduced into evidence in connection with the determination.
(d)
    In the event that Indemnitee is successful in seeking, pursuant to this Section 12, a judicial adjudication of or an award in arbitration to enforce Indemnitee’s rights under, or to recover damages for breach of, this Agreement, Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company for, any and all Expenses actually and reasonably incurred by him or her in such judicial adjudication or arbitration.  If it shall be determined in such judicial adjudication or arbitration that Indemnitee is entitled to receive part but not all of the indemnification or advance of Expenses sought, the Expenses incurred by Indemnitee in connection with such judicial adjudication or arbitration shall be appropriately prorated.  
(e)
    Interest shall be paid by the Company to Indemnitee at the maximum rate allowed to be charged for judgments under the Courts and Judicial Proceedings Article of the Annotated Code of Maryland for amounts which the Company pays or is obligated to pay for the period (i) commencing with either the tenth day after the date on which the Company was requested to advance Expenses in accordance with Sections 8 or 9 of this Agreement or the 60th day after the date on which the Company was requested to make the determination of entitlement to indemnification under Section 10(b) of this Agreement, as applicable, and (ii) ending on the date such payment is made to Indemnitee by the Company.
(f)
    The parties further agree to waive trial by jury with respect to the determination whether Indemnitee is entitled to indemnification or advance of Expenses.
Section 13.
    Defense of the Underlying Proceeding.
(a)
    Indemnitee shall notify the Company promptly in writing upon being served with any summons, citation, subpoena, complaint, indictment, request or other document relating to any Proceeding which may result in the right to indemnification or the advance of Expenses hereunder and shall include with such notice a description of the nature of the Proceeding and a summary of the facts underlying the Proceeding.  The failure to give any such notice shall not disqualify Indemnitee from the right, or otherwise affect in any manner any right of Indemnitee, to indemnification or the advance of Expenses under this Agreement unless the Company’s ability to defend in such Proceeding or to obtain proceeds under any insurance policy is materially and adversely prejudiced thereby, and then only to the extent the Company is thereby actually so prejudiced.
(b)
    Subject to the provisions of the last sentence of this Section 13(b) and of Section 13(c) below, the Company shall have the right to defend Indemnitee in any Proceeding which may give rise to indemnification hereunder; provided, however, that the Company shall notify Indemnitee of any such decision to defend within 15 calendar days following receipt of notice of any such Proceeding under Section 13(a) above.  The Company shall not, without the prior written consent of Indemnitee, consent to the entry of any judgment against Indemnitee or enter into any settlement or compromise which (i) includes an admission of fault of Indemnitee, (ii) does not include, as an unconditional term thereof, the full release of Indemnitee from all liability in respect of such Proceeding, which release shall be in form and substance reasonably satisfactory to Indemnitee or (iii) would impose any Expense, judgment, fine, penalty or limitation on Indemnitee.  This Section 13(b) shall not apply to a Proceeding brought by Indemnitee under Section 12 of this Agreement.
(c)
    Notwithstanding the provisions of Section 13(b) above, if in a Proceeding to which Indemnitee is a party by reason of Indemnitee’s Corporate Status, (i) Indemnitee reasonably concludes, based upon an opinion of counsel approved by the Company, which approval shall not be unreasonably withheld or delayed, that Indemnitee may have separate defenses or counterclaims to assert with respect to any issue which may not be consistent with other defendants in such Proceeding, (ii) Indemnitee reasonably concludes, based upon an opinion of counsel approved by the Company, which approval shall not be unreasonably withheld or delayed, that an actual or apparent conflict of interest or potential conflict of interest exists between Indemnitee and the Company, or (iii) if the Company fails to assume the defense of such Proceeding in a timely manner, Indemnitee shall be entitled to be represented by separate legal counsel of Indemnitee’s choice, subject to the prior approval of the Company, which approval shall not be unreasonably withheld or delayed, at the expense of the Company.  In addition, if the Company fails to comply with any of its obligations under this Agreement or in the event that the Company or any other person takes any action to declare this Agreement void or unenforceable, or institutes any Proceeding to deny or to recover from Indemnitee the benefits intended to be provided to Indemnitee hereunder, Indemnitee shall have the right to retain counsel of Indemnitee’s choice, subject to the prior approval of the Company, which approval shall not be unreasonably withheld or delayed, at the expense of the Company (subject to Section 12(d) of this Agreement), to represent Indemnitee in connection with any such matter.
(d)
    In connection with any Proceeding in which the Company has agreed to advance Expenses or provide indemnification to Indemnitee (whether or not Indemnitee has provided notice as contemplated by Section 13(a) above), Indemnitee shall assist and cooperate with the Company in any manner reasonably requested by the Company, including providing to the Company’s legal counsel, any information related to Indemnitee’s knowledge of the facts concerning the issues encompassed by such Proceedings which is not subject to Indemnitee’s personal attorney-client privilege or otherwise protected from disclosure as to the Company and which is reasonably available to Indemnitee.
Section 14.
    Non-Exclusivity; Survival of Rights; Subrogation.
(a)
    The rights of indemnification and advance of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the charter or Bylaws of the Company, any agreement entered into after the date hereof or a resolution of the stockholders entitled to vote generally in the election of directors or of the Board of Directors, or otherwise.  Unless consented to in writing by Indemnitee, no amendment, alteration or repeal of the Company’s Charter, the Company’s Bylaws, this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in Indemnitee’s Corporate Status prior to such amendment, alteration or repeal, regardless of whether a claim with respect to such action or inaction is raised prior or subsequent to such amendment, alteration or repeal.  No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right or remedy shall be cumulative and in addition to every other right or remedy given hereunder or now or hereafter existing at law or in equity or otherwise.  The assertion of any right or remedy hereunder, or otherwise, shall not prohibit the concurrent assertion or employment of any other right or remedy.
(b)
    In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.
Section 15.
    Insurance.  
(a)
    The Company will use its reasonable best efforts to acquire directors and officers liability insurance, on terms and conditions deemed appropriate by the Board of Directors covering Indemnitee for any claim made against Indemnitee by reason of Indemnitee’s Corporate Status and covering the Company for any indemnification or advance of Expenses made by the Company to Indemnitee for any claims made against Indemnitee by reason of Indemnitee’s Corporate Status. To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees or agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any other person with a similar title or role with the Company. In the event of a Change in Control, the Company shall maintain in force any and all directors and officers liability insurance policies that were maintained by the Company immediately prior to the Change in Control for a period of six years with the insurance carrier or carriers in place at the time of the Change in Control; provided, however, (i) if the carriers will not offer the same policy and an expiring policy needs to be replaced, a policy substantially comparable in scope and amount shall be obtained and (ii) if any replacement insurance carrier is necessary to obtain a policy substantially comparable in scope and amount, such insurance carrier shall have an AM Best rating that is the same or better than the AM Best rating of the existing insurance carrier; provided, further, however, in no event shall the Company be required to expend in the aggregate in excess of 250% of the annual premium or premiums paid by the Company for directors and officers liability insurance in effect on the date of the Change in Control. In the event that 250% of the annual premium paid by the Company for such existing directors and officers liability insurance is insufficient for such coverage, the Company shall spend up to that amount to purchase such lesser coverage as may be obtained with such amount.  In the event that the Company receives notice of cancellation, threatened or future cancellation or nonrenewal of any policy providing such directors and officers liability insurance, it shall promptly give notice of such cancellation, threatened or future cancellation or nonrenewal to Indemnitee.
(b)
    Without in any way limiting any other obligation under this Agreement, the Company shall indemnify Indemnitee for any payment by Indemnitee which would otherwise be indemnifiable hereunder arising out of the amount of any deductible or retention and the amount of any excess of the aggregate of all judgments, penalties, fines, settlements and Expenses incurred by Indemnitee in connection with a Proceeding over the coverage of any insurance referred to in Section 15(a).  The purchase, establishment and maintenance of any such insurance shall not in any way limit or affect the rights or obligations of the Company or Indemnitee under this Agreement except as expressly provided herein, and the execution and delivery of this Agreement by the Company and Indemnitee shall not in any way limit or affect the rights or obligations of the Company under any such insurance policies.  If, at the time the Company receives notice from any source of a Proceeding to which Indemnitee is a party or a participant (as a witness or otherwise) the Company has director and officer liability insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies.
(c)
    Indemnitee shall cooperate with the Company or any insurance carrier of the Company with respect to any investigation or Proceeding.
Section 16.
    Coordination of Payments.  The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable or payable or reimbursable as Expenses hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.
Section 17.
    Contribution.  
(a)
    If the indemnification provided in this Agreement is unavailable in whole or in part and may not be paid to Indemnitee for any reason, other than for failure to satisfy the standard of conduct set forth in Section 4 or due to the provisions of Section 5, then, with respect to any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), to the fullest extent permissible under applicable law, the Company, in lieu of indemnifying and holding harmless Indemnitee, shall pay, in the first instance, the entire amount incurred by Indemnitee, whether for Expenses, judgments, penalties, and/or amounts paid or to be paid in settlement, in connection with any Proceeding without requiring Indemnitee to contribute to such payment, and the Company hereby waives and relinquishes any right of contribution it may have at any time against Indemnitee. 
(b)
    Without diminishing or impairing the obligations of the Company set forth in Section 17(a) and provided Indemnitee has met the requisite standard of conduct set forth in Section 4, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the Company shall contribute to the amount of Expenses, judgments, penalties, and/or amounts actually incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which such Proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such Expenses, judgments, penalties and/or amounts paid in settlement, as well as any other equitable considerations. The relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is active or passive.
(c)
    Provided that Indemnitee has met the requisite standard of conduct set forth in Section 4, the Company hereby agrees to fully indemnify and hold harmless Indemnitee from any claims for contribution which may be brought by officers, directors or employees of the Company other than Indemnitee who may be jointly liable with Indemnitee.
Section 18.
    Reports to Stockholders.  To the extent required by the MGCL, the Company shall report in writing to its stockholders the payment of any amounts for indemnification of, or advance of Expenses to, Indemnitee under this Agreement arising out of a Proceeding by or in the right of the Company with the notice of the meeting of stockholders of the Company next following the date of the payment of any such indemnification or advance of Expenses or prior to such meeting.
Section 19.
    Duration of Agreement; Binding Effect.
(a)
    This Agreement shall continue until and terminate on the later of (i) the date that Indemnitee shall have ceased to serve as a director, officer, employee or agent of the Company or as a director, trustee, officer, partner, manager, managing member, fiduciary, employee or agent of any other foreign or domestic corporation, real estate investment trust, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving in such capacity at the request of the Company and (ii) the date that Indemnitee is no longer subject to any actual or possible Proceeding (including any rights of appeal thereto and any Proceeding commenced by Indemnitee pursuant to Section 12 of this Agreement).  
(b)
    The indemnification and advance of Expenses provided by, or granted pursuant to, this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or a director, trustee, officer, partner, manager, managing member, fiduciary, employee or agent of any other foreign or domestic corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving in such capacity at the request of the Company, and shall inure to the benefit of Indemnitee and Indemnitee’s spouse, assigns, heirs, devisees, executors and administrators and other legal representatives.
(c)
    The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.
(d)
    The Company and Indemnitee agree that a monetary remedy for breach of this Agreement, at some later date, may be inadequate, impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm.  Accordingly, the parties hereto agree that Indemnitee may enforce this Agreement by seeking injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining any other relief to which Indemnitee may be entitled.  Indemnitee shall further be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions, without the necessity of posting bonds or other undertakings in connection therewith.  The Company acknowledges that, in the absence of a waiver, a bond or undertaking may be required of Indemnitee by a court, and the Company hereby waives any such requirement of such a bond or undertaking.
Section 20.
    Severability.  If any provision or provisions of this Agreement shall be held to be invalid, void, illegal or otherwise unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby. If any provision or provisions of this Agreement shall be determined to be invalid  or unenforceable, the Company in good faith shall expeditiously take all necessary or appropriate action to provide Indemnitee with rights under this Agreement (including with respect to indemnification, advance of Expenses and other rights) that effect the original intent of this Agreement as closely as possible.
Section 21.
    Counterparts.  This Agreement may be executed in two (2) or more counterparts (delivery of which may be by facsimile, or via email as a portable document format (.pdf) or other electronic format), each of which will be deemed an original, and it will not be necessary in making proof of this Agreement or the terms of this Agreement to produce or account for more than one (1) of such counterparts. One such counterpart signed by the party against whom enforceability is sought shall be sufficient to evidence the existence of this Agreement.
Section 22.
    Headings.  The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof.
Section 23.
    Modification and Waiver.  No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto.  No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor, unless otherwise expressly stated, shall such waiver constitute a continuing waiver.
Section 24.
    Notices.  All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given if (i) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, on the day of such delivery, or (ii) mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed:
(a)
    If to Indemnitee, to the address set forth on the signature page hereto.
(b)
    If to the Company, to:
CyrusOne Inc.

Carrollton, TX 75007
Attn: General Counsel


or to such other address as may have been furnished in writing to Indemnitee by the Company or to the Company by Indemnitee, as the case may be.


Section 25.
    Spousal Indemnification.  The Company shall provide Indemnitee’s spouse to whom Indemnitee is legally married at any time Indemnitee is covered under the indemnification provided in this Agreement (even if Indemnitee did not remain married to him or her during the entire period of coverage) indemnification and contribution against any Proceeding for the same period, to the same extent and subject to the same standards, limitations, obligations and conditions under which indemnification and contribution is provided herein, if Indemnitee’s spouse (or former spouse) becomes involved in a Proceeding solely by reason of his or her status as Indemnitee’s spouse. Including, without limitation, any Proceeding that seeks damages recoverable from marital community property, jointly-owned property or property purported to have been transferred from Indemnitee to his or her spouse (or former spouse). Indemnitee’s spouse or former spouse also shall be entitled to advance of Expenses to the same extent that Indemnitee is entitled to advance of Expenses provided under Section 8 or 9 of this Agreement. The Company may maintain insurance to cover its obligations hereunder with respect to Indemnitee’s spouse (or former spouse) or set aside assets in a trust or escrow fund for that purpose; provided, however, that the Company agrees that the provisions of this Agreement shall remain in effect regardless of whether such liability or other insurance coverage is obtained or retained by the Company; except that any payments made to, or on behalf of, Indemnitee’s spouse under such an insurance policy shall reduce the obligations of the Company hereunder.
Section 26.
    Time is of the Essence. The parties expressly agree that time is of the essence with respect to all provisions of this Agreement.
Section 27.
    Governing Law.  This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of Maryland, without regard to its conflicts of laws rules.

Terms used herein and not otherwise defined shall have the meanings specified in the Indemnification Agreement.
I am subject to the Proceeding by reason of my Corporate Status or by reason of alleged actions or omissions by me in such capacity.

In consideration of the advance by the Company for Expenses incurred by me in connection with the Proceeding (the “Advanced Expenses”), I hereby agree that if, in connection with the Proceeding, it is established that (1) an act or omission by me was material to the matter giving rise to the Proceeding and (a) was committed in bad faith or (b) was the result of active and deliberate dishonesty or (2) I actually received an improper personal benefit in money, property or services or (3) in the case of any criminal proceeding, I had reasonable cause to believe that the act or omission was unlawful, then I shall promptly reimburse the portion of the Advanced Expenses relating to the claims, issues or matters in the Proceeding as to which the foregoing findings have been established.  
IN WITNESS WHEREOF, I have executed this Affirmation and Undertaking on this ___ day of ____________________, 20____.
