Subject to Sections 2(c) and 2(e) below and the last sentence of this Section 2(a), the Company will use commercially reasonable efforts (i) to file a Resale Registration Statement (which will be a “shelf” Resale Registration Statement under Rule 415 promulgated under the Securities Act if requested pursuant to GC LLC Holder’s’ request pursuant to the first sentence of this Section 2(a)) registering for resale such number of Registrable Shares as requested to be so registered within 30 days in the case of a registration on Form S-3 (and 60 days in the case of a registration on Form S-11 or such other appropriate form) after GC LLC Holder’s’ request therefor, and (ii) to cause such Resale Registration Statement to be declared effective by the SEC as soon as reasonably practicable thereafter. Notwithstanding the foregoing, the Company will not be required to effect a registration pursuant to this Section 2(a): (i) with respect to securities that are not Registrable Shares, or (ii) within 180 days after the effective date of a prior Demand Registration (other than any such registration on Form S-3) in respect of the Company’s Common Shares. If permitted under the Securities Act, such Resale Registration Statement will be one that is automatically effective upon filing. Notwithstanding anything to the contrary contained in this Section 2(a), if at the time the Company receives a request for a Demand Registration, the Company has an effective shelf registration statement, the Company may include all or part of the Registrable Shares covered by such request in such registration statement, including by virtue of including the Registrable Shares in a prospectus supplement to such shelf registration statement and filing such prospectus supplement pursuant to Rule 424(b)(7) under the Securities Act (in which event, the Company shall be deemed to have satisfied its registration obligation under this Section 2(a) with respect to such Demand Registration request and such shelf registration statement shall be deemed to be a Resale Registration Statement for purposes of this Agreement. (b) If such Demand Registration is in respect of an underwritten offering and the managing underwriters of the requested Demand Registration advise the Company and GC LLC Holder that in the reasonable opinion of the managing underwriters the number of shares of Common Shares proposed to be included in the Demand Registration exceeds the number of shares of Common Shares that can be sold in such underwritten offering without materially delaying or jeopardizing the success of the offering (including the offering price per share) (such number of shares, the “Maximum Number of Shares”), the

6 Company will include in such Demand Registration only such number of shares of Common Shares that, in the reasonable opinion of the managing underwriters, can be sold without materially delaying or jeopardizing the success of the offering (including the offering price per share), with such Maximum Number of Shares allocated (1) first, to the shares of Common Shares that GC LLC Holder and, if included in such Demand Registration pursuant to Section 2(a), any other Holder of Registrable Shares proposes to sell and (2) second, to the shares of Common Shares proposed to be included therein by any other Persons (including shares of Common Shares to be sold for the account of the Company or other holders of Common Shares) allocated among such Persons in such manner as they may agree. (c) If any of the Registrable Shares covered by a Demand Registration are to be sold in an underwritten offering, the Company shall have the right to (i) select the underwriters (and their roles) in the offering, provided that such underwriters are reasonably acceptable to GC LLC Holder; and (ii) determine the structure of the offering and negotiate the terms of any underwriting agreement as they relate to GC LLC Holder and, if included in such Demand Registration pursuant to Section 2(a), any other Holder, including the number of shares to be sold (if not all shares offered can be sold at the highest price offered by the underwriters), the offering price and underwriting discount; provided that such structure and terms are acceptable to GC LLC Holder, in its sole discretion. (d) Notwithstanding the foregoing, if the Board determines in its good faith judgment that the filing of a Demand Registration would (i) be seriously detrimental to the Company in that such registration would interfere with a material corporate transaction, or (ii) require the disclosure of material non-public information concerning the Company that at the time is not, in the good faith judgment of the Board, in the best interest of the Company to disclose and is not, in the opinion of the Company’s counsel, otherwise required to be disclosed, then (x) the Company will have the right to defer such filing for a period of not more than 60 days after receipt of any demand by GC LLC Holder, and (y) the Company will not exercise its right to defer a Demand Registration more than once in any 12-month period. The Company will give written notice of its determination to GC LLC Holder to defer the filing and of the fact the purpose for such deferral no longer exists, in each case, promptly after the occurrence thereof. (e) Upon the effectiveness of any Demand Registration, the Company will use commercially reasonable efforts to keep the Resale Registration Statement continuously effective until such time as all of the Registrable Shares covered by such Demand Registration have been sold pursuant to such Demand Registration. (f) If, by the third anniversary (the “Renewal Deadline”) of the initial effective date of a Resale Registration Statement filed pursuant to Section 2(a), any of the Registrable Shares remain unsold by GC LLC Holder or, if included in such Demand Registration pursuant to Section 2(a), any other Holder of Registrable Securities included on such registration statement, the Company will file, if it has not already done so and is eligible to do so, a new Resale Registration Statement covering the Registrable Shares included on the prior Resale Registration Statement; if at the Renewal Deadline the Company is not eligible to file an automatic shelf registration statement, the Company will, if it has not already done so,

7 file a new Resale Registration Statement and will use commercially reasonable efforts to cause such Resale Registration Statement to be declared effective within 180 days after the Renewal Deadline; and the Company will take all other action necessary or appropriate to permit public offering and sale of the Registrable Shares to continue as contemplated in the expired Resale Registration Statement. References herein to Resale Registration Statement shall include such new shelf registration statement. Section 3. Piggyback Registration. (a) If at any time the Company has registered, or has determined to register, any of its securities for its own account or for the account of other security holders of the Company on any registration form (other than Form S-4 or S-8) that permits the inclusion of the Registrable Shares (a “Piggyback Registration”), the Company will give GC LLC Holder written notice thereof promptly (but in no event less than five (5) Business Days prior to the anticipated filing date) and, subject to Section 3(b), will include in such registration all Registrable Shares to be offered by GC LLC Holder requested to be included therein pursuant to the written request of GC LLC Holder. (b) If a Piggyback Registration is initiated as a primary underwritten offering on behalf of the Company, and the managing underwriters advise the Company and GC LLC Holder that, in the reasonable opinion of the managing underwriters, the number of shares of Common Shares proposed to be included in such registration exceeds the Maximum Number of Shares, the Company will include in such registration, unless otherwise agreed by the Company and GC LLC Holder, (i) first, the number of shares of Common Shares that the Company proposes to sell, and (ii) second, the Registrable Shares of GC LLC Holder. (c) If a Piggyback Registration is initiated as an underwritten registration on behalf of a holder of shares of Common Shares other than under this Agreement, and the managing underwriters advise the Company that, in the reasonable opinion of the managing underwriters, the number of shares of Common Shares proposed to be included in such registration exceeds the Maximum Number of Shares, then the Company will include in such registration, unless otherwise agreed by the Company and the holders (including GC LLC Holder), (i) first the number of shares of Common Shares requested to be included therein by the holder(s) requesting such registration, and (ii) second, (to the extent the amount of such shares of Common Shares to be sold by such other holders is less that the Maximum Number of Shares), the Registrable Shares requested to be included in such registration by GC LLC Holder and the shares of Common Shares requested to be included in such registration by other holders, pro rata among the GC LLC Holder and other holders on the basis of the number of Registrable Shares and other shares of Common Shares requested to be included by each such GC LLC Holder and other holder, respectively. (d) If any Piggyback Registration is a primary or secondary underwritten offering, the Company will have the right to select, in its sole discretion, the managing underwriter or underwriters to administer any such offering.

8 (e) The Company will not grant to any Person the right to request the Company to register any Common Shares in a Piggyback Registration unless such rights are consistent with the provisions of this Section 3. (f) Nothing in this Section 3 shall create any liability on the part of the Company to GC LLC Holder if the Company in its sole discretion decides not to file a registration statement previously proposed to be filed as described in Section 3(a) or to withdraw any such registration statement subsequent to its filing, regardless of any action whatsoever that GC LLC Holder may have taken, whether as a result of the issuance by the Company of any notice hereunder or otherwise. Furthermore, nothing in this Section 3 shall apply in the case of a registration by the Company of any of its securities for its own account on a registration statement in connection with an “at-the-market” offering (as defined in Rule 415 under the Securities Act). Section 4. Suspension. (a) Subject to the provisions of this Section 4 and a good faith determination by the Company that it is in the best interests of the Company to suspend the use of any Resale Registration Statement, following the effectiveness of such Resale Registration Statement (and the filings with any U.S. federal or state securities commission), the Company, by written notice to Holder, may direct Holder to suspend sales of the Registrable Shares pursuant to such Resale Registration Statement for such time periods as the Company reasonably may determine is necessary and advisable (but in no event for more than 30 days in any 90-day period or 90 days in any 365-day period), if any of the following events will occur: (i) an underwritten public offering of Common Shares by the Company if the Company is advised by the underwriters that the concurrent resale of the Registrable Shares by Holder pursuant to the Resale Registration Statement would have a material adverse effect on the Company’s offering, (ii) there is material non-public information regarding the Company that (A) the Company determines not to be in the Company’s best interest to disclose, (B) would, in the good faith determination of the Company, require a revision to the Resale Registration Statement so that it will not contain any 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, in light of the circumstances under which they were made, not misleading, and (C) the Company is not otherwise required to disclose, or (iii) there is a significant bona fide business opportunity (including the acquisition or disposition of assets (other than in the ordinary course of business), including any significant merger, consolidation, tender offer or other similar transaction) available to the Company that the Company determines not to be in the Company’s best interests to disclose. (b) Upon the earlier to occur of (i) the Company delivering to Holder an End of Suspension Notice (as defined below), or (ii) the end of the maximum permissible suspension period, the Company will use commercially reasonable efforts to promptly amend or supplement the Resale Registration Statement so as to permit Holder to resume sales of the Registrable Shares as soon as possible. (c) In the case of an event that causes the Company to suspend the use of a Resale Registration Statement (a “Suspension Event”), the Company will give written notice (a “Suspension Notice”) to

9 Holder to suspend sales of the Registrable Shares, and such notice will state that such suspension will continue only for so long as the Suspension Event or its effect is continuing and the Company is taking all reasonable steps to terminate suspension of the effectiveness of the Resale Registration Statement as promptly as possible. Holder will not affect any sales of the Registrable Shares pursuant to such Resale Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company prior to receipt of an End of Suspension Notice (as defined below). If so directed by the Company, Holder will deliver to the Company (at the reasonable expense of the Company) all copies other than permanent file copies then in Holder’s possession of the Prospectus covering the Registrable Shares at the time of receipt of the Suspension Notice. Holder may recommence effecting sales of the Registrable Shares pursuant to the Resale Registration Statement (or such filings) following further notice to such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice will be given by the Company to Holder in the manner described above promptly following the conclusion of any Suspension Event and its effect.

(b) Holder will indemnify and hold harmless the Company, and the trustees of the Company, each officer of the Company who will sign a Resale Registration Statement, each underwriter, broker or other Person acting on behalf of the holders of securities included in a Resale Registration Statement, and each Person who controls any of the foregoing Persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) against any Losses, as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in a Resale Registration Statement or any Prospectus or in any amendment or supplement thereto or in any preliminary Prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, but only to the extent that (i) such untrue statement or omission is based upon information regarding Holder furnished in writing to the Company by or on behalf of Holder expressly for use therein, or (ii) such information relates to Holder or Holder’s proposed method of distribution of the Registrable Shares and was approved in writing by or on behalf of

14 Holder expressly for use in the Resale Registration Statement, such Prospectus or in any amendment or supplement thereto. (c) Each Indemnified Party under this Section 8 will give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, but the omission to so notify the Indemnifying Party will not relieve it from any liability which it may have to the Indemnified Party pursuant to the provisions of this Section 8 except to the extent of the actual damages suffered as a result of such delay in notification. The Indemnifying Party will assume the defense of such action, including the employment of counsel to be chosen by the Indemnifying Party to be reasonably satisfactory to the Indemnified Party, and payment of expenses. The Indemnified Party will have the right to employ its own counsel in any such case, but the legal fees and expenses of such counsel will be at the expense of the Indemnified Party, unless (i) the employment of such counsel will have been authorized in writing by the Indemnifying Party in connection with the defense of such action, (ii) the Indemnifying Party will not have employed counsel to take charge of the defense of such action or (iii) the Indemnified Party will have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to the Indemnifying Party (in which case the Indemnifying Party will not have the right to direct the defense of such action on behalf of the Indemnified Party), in any of which events such fees and expenses will be borne by the Indemnifying Party. No Indemnifying Party, in the defense of any such claim or litigation, will, except with the consent of each Indemnified Party, consent to the entry of any judgment or enter into any settlement unless such judgment or settlement (i) includes as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any Indemnified Party. (d) If the indemnification provided for in this Section 8 is unavailable to a party that would have been an Indemnified Party under this Section 8 in respect of any expenses, claims, losses, damages and liabilities referred to herein, then each party that would have been an Indemnifying Party hereunder will, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such expenses, claims, losses, damages and liabilities in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand, and such Indemnified Party on the other, in connection with the statement or omission which resulted in such expenses, claims, losses, damages or liabilities, in reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Indemnifying Party or such Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and Holder agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable consideration referred to above in this Section 8(d).

15 (e) No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. (f) In no event will any Holder be liable for any expenses, claims, losses, damages or liabilities pursuant to this Section 8 in excess of the net proceeds to Holder of any Registrable Shares sold by Holder in any relevant offering. Section 9. Rule 144. The Company shall, at the Company’s expense, for so long as any Holder holds any Registrable Shares, use commercially reasonable efforts to cooperate with Holder, as may be reasonably requested by Holder from time to time, to facilitate any proposed sale of Registrable Shares by Holder in accordance with the provisions of Rule 144, including by using commercially reasonable efforts (i) to comply with the current public information requirements of Rule 144 and (ii) to provide opinions of counsel as may be reasonably necessary in order for Holder to avail itself of such rule to allow Holder to sell such Registrable Shares without registration. Section 10. Transfer of Registration Rights. The rights and obligations of GC LLC under this Agreement (other than the limitation set forth in the second parenthetical of clause (c) of the definition of Registrable Shares, which shall only apply to Registrable Shares held by GC LLC Holder and no other transferee or assignee) may be transferred or otherwise assigned to a transferee or assignee of Registrable Shares, provided (i) such transferee or assignee becomes a party to this Agreement or agrees in writing to be subject to the terms hereof to the same extent as if such transferee or assignee were an original party hereunder, and (ii) the Company is given written notice by GC LLC of such transfer or assignment stating the name and address of such transferee or assignee and identifying the securities with regard to which such rights and obligations are being transferred or assigned. Section 11. Miscellaneous. (a) Governing Law; Jurisdiction; Waiver of Jury Trial. This Agreement and any claim, controversy or dispute arising under or related in any way to this Agreement, the relationship of the parties, the transactions contemplated by this Agreement and/or the interpretation and enforcement of the rights and duties of the parties hereunder or related in any way to the foregoing, will be governed by and construed in accordance with the laws of the State of Maryland without giving effect to any choice or conflict of law provision or rule (whether of the State of Maryland or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Maryland.

ANY PARTY MAY MAKE SERVICE ON ANY OTHER PARTY BY SENDING OR DELIVERING A COPY OF THE PROCESS TO THE PARTY TO BE SERVED AT THE ADDRESS AND IN THE MANNER PROVIDED FOR THE GIVING OF NOTICES IN SECTION 11(E). NOTHING IN THIS SECTION 11(A), HOWEVER, WILL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR AT EQUITY. EACH PARTY AGREES THAT A FINAL JUDGMENT IN ANY ACTION OR PROCEEDING SO BROUGHT WILL BE CONCLUSIVE AND MAY BE ENFORCED BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW OR AT EQUITY. EACH OF THE PARTIES HEREBY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS AND OBLIGATIONS. EACH OF THE PARTIES (I) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (II) ACKNOWLEDGES THAT SUCH OTHER PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE WAIVERS AND CERTIFICATIONS CONTAINED HEREIN.

To the extent permitted by law, the parties hereby to the same extent waive any provision of law that renders any provision hereof prohibited or unenforceable in any respect. (h) Section Titles. Section titles are for descriptive purposes only and will not control or alter the meaning of this Agreement as set forth in the text. (i) Successors and Assigns. This Agreement shall be binding upon the parties hereto and their respective successors and permitted assigns and will inure to the benefit of the parties hereto and their respective successors and permitted assigns. In the event that the Company or any of its successors or permitted assigns (i) consolidates or amalgamates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation, amalgamation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case as a condition thereto, the Company (or its successors or permitted assigns) shall cause such Person to assume the obligations of the Company set forth in this Agreement.

19 law or otherwise, (a) such successor or permitted assignee will be entitled to all of the benefits of GC LLC under this Agreement and (b) such Registrable Shares will be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Shares such Person will be conclusively deemed to have agreed to be bound by all of the terms and provisions hereof. (j) Remedies; No Waiver. Each party acknowledges and agrees that the other parties would be irreparably damaged in the event that the covenants set forth in this Agreement were not performed in accordance with its specific terms or were otherwise breached. It is accordingly agreed that each party hereto will be entitled to seek an injunction to specifically enforce the terms of this Agreement solely in the courts specified in Section 11(a), in addition to any other remedy to which such party may be entitled hereunder, at law or in equity. No failure or delay by a party in exercising any right or remedy provided by law or under this Agreement will impair such right or remedy or operate or be construed as a waiver or variation of it or preclude its exercise at any subsequent time and no single or partial exercise of any such right or remedy will preclude any further exercise of it or the exercise of any other remedy. (k) Attorneys’ Fees. If Holder brings an action to enforce its rights under this Agreement, the prevailing party in the action is entitled to recover its costs and expenses, including reasonable attorneys’ fees, incurred in connection with such action, including any appeal of such action. (l) Changes in Securities Laws. In the event any amendment, repeal or other change in the securities laws will render the provisions of this Agreement inapplicable, the Company will provide Holder with substantially similar rights to those granted under this Agreement and use its good faith efforts to cause such rights to be as comparable as possible to the rights granted to Holder hereunder.
