NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and promises contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby mutually acknowledged, Sublandlord and Subtenant hereby agree as follows:

1. Demise; Use. Sublandlord hereby subleases to Subtenant and Subtenant hereby subleases from Sublandlord the Subleased Premises for the term and rental and upon the other terms and conditions hereinafter set forth, to be used and occupied by Subtenant solely for general office use and for no other purpose.

2. Term.

(a) Subject to subsection (b) below, the term of this Sublease shall commence on January 1, 2013 (the “Commencement Date”), and, unless sooner terminated pursuant to the provisions hereof, shall terminate on May 25, 2024, or any earlier date as of which the Prime Lease may be terminated. As soon as practicable following September 1, 2012, Sublandlord shall provide Subtenant access (“Early Access”) to the Subleased Premises for the exclusive purpose of installing Subtenant’s telecommunications and data cabling and equipment. During such period of Early Access, all of the provisions of this Sublease shall be in effect, except for Subtenant’s obligation to pay Base Rent or additional rent, and except for Subtenant’s right to use the Subleased Premises for the operation of its business. Subtenant shall coordinate its telecommunications and data work with Sublandlord to avoid interference with completion of the Subleasehold Improvements.

(b) Notwithstanding anything to the contrary in this Sublease, if Sublandlord has not completed the Subleasehold Improvements and provided Subtenant with Early Access on or before December 15, 2012, then the Commencement Date shall be delayed by one day for each day after December 15, 2012 that elapses before Sublandlord completes the Subleasehold Improvements and provides Subtenant with Early Access.

3. Base Rent.

(a) Subtenant shall pay to Sublandlord base rental (“Base Rent”) for the Subleased Premises as follows:

Base Rent shall be due and payable in equal monthly installments. Each such installment shall be due and payable in advance on the first day of each calendar month of the term hereof. If the term of this Sublease commences on a day other than the first day of a month or ends on a day other than the last day of a month, Base Rent for such month shall be prorated; prorated Base Rent for any such partial first month of the term hereof shall be paid on the date on which the term commences. Concurrently with its execution of this Sublease, Subtenant shall pay to Sublandlord the installment of Base Rent due for the first full calendar month within the term of this Sublease following the abatement period described in Section 3(c) below.

2

(b) Except as otherwise provided in this Sublease, all Base Rent and additional rent shall be paid without any notice, setoff or deduction whatsoever, and shall be paid to Sublandlord at its address set forth in Section 15 below or at such other place as Sublandlord may designate by notice to Subtenant.

(c) Notwithstanding anything to the contrary set forth above, so long as Subtenant is not in default hereunder beyond any applicable notice and cure period, Base Rent payable by Subtenant to Sublandlord as provided above shall be abated for the first five (5) months of the term of this Sublease. If the Commencement Date is later than January 1, 2013, then this 5-month abatement period shall be calculated by using a period of one hundred fifty (150) days from the Commencement Date. The date which is one calendar day after the end of the abatement period as defined in this paragraph, shall be called the “Post-Abatement Commencement Date”.

4. Additional Rent; Payments; Interest.

(a) In addition to the Base Rent described above, commencing on January 1, 2014, Subtenant shall pay to Sublandlord additional rent with respect to the Subleased Premises on account of Operating Expenses and Real Estate Taxes in accordance with the provisions of the Prime Lease; provided, however, that Subtenant shall be liable only for increases in Operating Expenses and Real Estate Taxes above a calendar year 2013 base year (the “Base Year”). Subtenant’s share of the Operating Expenses and Real Estate Taxes shall be 4.157% of increases billed to Sublandlord above the Base Year amounts.

(b) Subtenant shall pay to Sublandlord all other amounts payable by Sublandlord under the Prime Lease which are attributable to Subtenant, its agents, employees, customers or invitees. By way of example and not by way of limitation, charges by Landlord for furnishing air conditioning or heating at Subtenant’s request to the Subleased Premises at times in addition to those certain times specified in the Prime Lease, costs incurred by Landlord in repairing damage to the Building caused by an employee of Subtenant, increased insurance premiums due as a result of Subtenant’s use of the Subleased Premises, and amounts expended or incurred by Landlord on account of any default by Subtenant which gives rise to a default under the Prime Lease would be amounts payable by Subtenant pursuant to this Section 4(b).

(c) Each amount due pursuant to Section 4(a) and 4(b) above and each other amount payable by Subtenant hereunder, unless a date for payment of such amount is provided for elsewhere in this Sublease, shall be due and payable on the tenth day following the date on which Landlord or Sublandlord has given notice to Subtenant of the amount thereof, but in no event later than the date on which any such amount is due and payable under the Prime Lease.

(d) All amounts other than Base Rent payable to Sublandlord under this Sublease shall be deemed to be additional rent due under this Sublease. All past due installments of Base Rent and additional rent shall be subject to the same late charges and interest as are applicable to late payments under the Prime Lease.

3

(e) Subtenant shall pay directly to Landlord on or before the applicable due dates for all services requested by Subtenant that are billed by Landlord directly to Subtenant rather than through Sublandlord.

5. Condition of Subleased Premises and Construction of Improvements.

(a) Subtenant accepts the Subleased Premises in their current “as-is” condition; provided, however, that prior to the Commencement Date, Sublandlord, at its cost, will build-out the Subleased Premises in accordance with the scope of work attached hereto as Exhibit B (the “Subleasehold Improvements”). All of the Subleasehold Improvements shall be constructed using approved materials, in a good and workmanlike manner. Sublandlord shall complete the Subleasehold Improvements on or before December 15, 2012.

(b) Subtenant’s taking possession of the Subleased Premises shall be conclusive evidence as against Subtenant that the Subleased Premises were in good working order and satisfactory condition when Subtenant took possession. Upon the expiration of the term hereof, or upon any earlier termination of the term hereof or of Subtenant’s right to possession, Subtenant shall surrender the Subleased Premises in at least as good condition as at the commencement of the term hereof, ordinary wear and tear, casualty loss, and permitted alterations excepted.

17. Security Deposit.

(a) Concurrently with its execution of this Sublease, Subtenant shall deposit with Sublandlord Twenty-One Thousand One Hundred Twenty-Seven and 98/100 Dollars ($21,127.98) as security for the full and faithful performance of every provision of this Sublease to be performed by Subtenant. If Subtenant defaults with respect to any provision of this Sublease, including, but not limited to, the provisions relating to the payment of rent, Sublandlord may use, apply or retain all or any part of said security deposit for the payment of any rent and any other sum in default, or for the payment of any other amount which Sublandlord may spend or become obligated to spend by reason of Subtenant’s default or to compensate Sublandlord for any other loss or damage which Sublandlord may suffer by reason of Subtenant’s default. If any portion of said security deposit is so used or applied, Subtenant shall, within five (5) days after written demand therefor, deposit cash with Sublandlord in an amount sufficient to restore the security deposit to its original amount, and Subtenant’s failure to do so shall be a material breach of this Sublease. Except to the extent required by law, Sublandlord shall not be required to keep said security deposit separate from its general funds, and Subtenant shall not be entitled to interest on any security deposit. If Subtenant shall fully and faithfully perform every provision of this Sublease to be performed by it, said security deposit or any balance thereof shall be returned to Subtenant (or, at Sublandlord’s option, to the last assignee of Subtenant’s interest hereunder) within thirty (30) days after the expiration of the term and Subtenant’s vacation of the Subleased Premises. Nothing herein shall be construed to limit the amount of damages recoverable by Sublandlord or any other remedy to the security deposit.

(b) At Subtenant’s election, the security deposit may take the form either of cash or of an unconditional, irrevocable letter of credit (the “Letter of Credit”) from a U.S. banking institution reasonably acceptable to Sublandlord, insured by a federal insurance agency (“Issuer”). The Letter of Credit shall (i) meet the requirements of the “Uniform Customs and Practice for Documentary Credits,” ICC No. 500 (1993 Edition), (ii) name Sublandlord as beneficiary, (iii) be in the amount of the security deposit required hereunder, (iv) be payable in full or partial draws against Sublandlord’s sight draft, (v) include an “evergreen” provision which provides that the Letter of Credit shall be renewed automatically on an annual basis unless the Issuer delivers thirty (30) days prior written notice of cancellation to Sublandlord, (vi) have an initial expiration date no earlier than one year from the date of issue, and (vii) otherwise be in form and substance satisfactory to Sublandlord. In the event the Letter of Credit is ever not renewed when required hereunder, Sublandlord shall have the right to draw upon the Letter of Credit and hold the proceeds thereof as a cash security deposit.

18. Parking. During the term of this Sublease, Subtenant shall have the right to purchase two (2) monthly parking permits in the Building’s parking garage for each 1,000 square feet of rentable area in the Subleased Premises, upon the terms and conditions set forth in Article XXIV of the Prime Lease. Subtenant shall coordinate payment and parking passes directly with Landlord or the operator of the garage.

19. Furniture. Throughout the term of this Sublease, Subtenant shall be permitted to use the furniture located in the Subleased Premises on the date of this Sublease (the “Furniture”). The Furniture is provided in its “as-is” condition upon delivery of the Subleased Premises. Subtenant shall maintain the Furniture in good condition and repair, ordinary wear and tear excepted, and shall leave the Furniture in the Subleased Premises upon the expiration or

10

earlier termination of this Sublease. Sublandlord shall have no liability for moving the Furniture or any of Subtenant’s own personal property. Notwithstanding the foregoing, upon the written consent of Sublandlord, Subtenant may dispose of any Furniture that cannot be repaired at a reasonable cost or is beyond its useful life. Any furniture or other personal property purchased by Subtenant shall remain Subtenant’s property.

20. Rooftop Deck. Subject to rules and regulations developed by Sublandlord, Subtenant may have occasional scheduled access to the rooftop deck at the Building without additional charge. Such access is not intended to be a daily or frequent occurrence. Subtenant shall schedule use in advance with Sublandlord on an as-available basis. Subtenant acknowledges that Sublandlord is a regulated entity subject to strict security and confidentiality requirements; therefore, it shall not be unreasonable for Sublandlord to restrict access to the rooftop deck if required by a regulating authority or in Sublandlord’s discretion from time to time.

21. Signs. Subject to Landlord’s approval, Subtenant, at its sole expense, (i) may install one (1) Building-standard suite entry sign at the main entrance to the Subleased Premises, (ii) shall be entitled to one (1) listing on the Building directory in the main lobby of the Building, and (iii) Subtenant will be allowed to post the “DANAC” logo in vertical format on the glass panel next to the entrance door to the Premises.

22. Modifications. Sublandlord shall not amend the Prime Lease with respect to any provision that would affect Subtenant’s rights or obligations hereunder without the Subtenant’s prior written consent.

23. No Breach of Prime Lease. Sublandlord shall not do or permit to be done any act which may constitute a breach or violation of any term, covenant or condition of the Prime Lease and which is not cured within any cure period granted under the Prime Lease.

24. Consent of Landlord. The obligations of Sublandlord and Subtenant under this Sublease are conditioned and contingent upon Landlord consenting hereto by executing and delivering a counterpart of this Sublease or a separate instrument signifying its consent. In the event Landlord’s consent is not obtained within thirty (30) days after the date hereof, this Sublease shall be null and void, and neither Sublandlord nor Subtenant shall have any further obligations or liability hereunder or to each other with respect to the Subleased Premises.

25. Examination. Submission of this instrument for examination or signature by Subtenant does not constitute a reservation of or option for the Subleased Premises or in any manner bind Sublandlord, and no lease, sublease or obligation of Sublandlord shall arise until this instrument is signed and delivered by Sublandlord and Subtenant and the consent of Landlord is obtained as described in Section 24 above.

26. Guaranty. Contemporaneously with the execution and delivery of this Sublease, Subtenant shall cause John F. Jaeger (the “Guarantor”) to enter into a deliver to Sublandlord a duly executed Guaranty of Sublease in the form attached to this Sublease as Exhibit C (the “Guaranty”). Notwithstanding any provision of this Sublease to the contrary, the occurrence of

11

any of the following shall constitute an immediate Event of Default under this Sublease: (a) any failure by Guarantor to timely perform its obligations under the Sublease; (b) Guarantor shall at any time become the subject of a bankruptcy or insolvency proceeding, or shall otherwise become unable to pay his debts as they become due: or (c) Guarantor dies and his estate fails to expressly assume Guarantor’s obligations under this Sublease within thirty (30) days of Guarantor’s death. Provided there is no default under the Sublease, this Guaranty shall expire on the third anniversary of the date of the Post-Abatement Commencement Date, provided that such expiration shall not affect, release or otherwise limit any claims which may have been asserted against Guarantor pursuant to the Guaranty prior to such expiration date, all of which claims shall expressly survive such expiration.

Form of Guaranty

GUARANTY OF SUBLEASE

The undersigned John F. Jaeger, an individual (the “Guarantor”), hereby unconditionally and irrevocably guarantees to Sublandlord (a) the due and punctual payment in full (and not merely the collectability) of all Base Rent, additional rent, and all other amounts due and payable by DANAC, LLC, and its successors and assigns (collectively, “Subtenant”) under that certain Sublease dated July 17, 2012, by and between CapitalSource Finance LLC, as Sublandlord and Subtenant (as amended from time to time, the “Sublease”); and (b) the full and faithful performance and observance of all terms, covenants, and conditions contained in said Sublease to be performed or observed by Subtenant.

Guarantor expressly agrees that Sublandlord may, in its sole and absolute discretion, without notice to or further consent of Guarantor and without in any way releasing, affecting, or impairing the obligations and liabilities of Guarantor hereunder (a) waive compliance with any of the terms of the Sublease; (b) modify, amend, or change any provisions of the Sublease by agreement between Subtenant and Landlord; (c) grant extensions or renewals of the Sublease and/or effect any release, compromise, or settlement in connection therewith; (d) assign or otherwise transfer all or part of its interest in the Sublease, the Prime Lease (as defined in the Sublease), the Subleased Premises, or this Guaranty or any interest therein or herein; and (e) consent to an assignment, subletting, conveyance, or other transfer of all or any part of the interest of Subtenant in the Sublease.

If Subtenant holds over beyond the term of the Sublease, Guarantor’s obligations hereunder shall extend and apply with respect to the full and faithful performance and observance of all of the covenants, terms, and conditions of the Sublease and of any such modification thereof. This Guaranty, and all of the terms hereof, shall be binding on Guarantor and the successors, assigns, and legal representatives of Guarantor. Guarantor does not require and hereby waives all notices of Subtenant’s nonpayment, nonperformance, or nonobservance of the covenants, terms, and conditions of the Sublease. Guarantor hereby expressly waives all notices and demands otherwise required by law which Guarantor may lawfully waive.

Insofar as the payment by Subtenant of any sums of money to Sublandlord is involved, this Guaranty is a guaranty of payment and not of collection, and shall remain in full force and effect until payment in full to Sublandlord of all sums payable under the Sublease. Guarantor waives any right to require that Sublandlord bring any legal action against Subtenant before, simultaneously with, or after enforcing its rights and remedies hereunder against Guarantor. Sublandlord shall not be required to make any demand on Subtenant, apply any security deposit being held by Sublandlord on behalf of Subtenant or any other credit in favor of Subtenant, or otherwise pursue or exhaust its remedies against Subtenant before, simultaneously with, or after enforcing its rights and remedies hereunder against Guarantor. Neither Guarantor’s obligation to make payment in accordance with the terms of the Guaranty nor any remedy for the enforcement

thereof shall be impaired, modified, released, limited, or affected in any way by any impairment, modification, release, or limitation of the liability of Subtenant or its estate in bankruptcy, resulting from (a) the operation of any present or future provision of the Bankruptcy Code of the United States or from the decision of any court interpreting the same; (b) the rejection, or disaffirmance, of the Sublease in any such proceedings; or (c) the assumption and assignment or transfer of the Sublease by Subtenant or Subtenant’s bankruptcy trustee.

Guarantor represents and warrants that this Guaranty has been duly authorized, has been duly executed by Guarantor, and constitutes Guarantor’s valid and legally binding agreement in accordance with its terms. The liability of Guarantor is coextensive with that of Subtenant and also joint and several, and legal action may be brought against Guarantor and carried to final judgment either with or without making Subtenant a party thereto. Until all of Subtenant’s obligations under the Sublease are fully performed, Guarantor (a) waives any rights that Guarantor may have against Subtenant by reason of any one or more payments or acts in compliance with the obligations of Guarantor under this Guaranty; and (b) subordinates any liability of indebtedness of Subtenant held by Guarantor to the obligations of Subtenant to Sublandlord under its Sublease.

Provided there is no default under the Sublease, this Guaranty shall expire on the third anniversary of the Post-Abatement Rent Commencement Date in the Sublease, provided that such expiration shall not affect, release or otherwise limit any claims which may have been asserted against Guarantor pursuant to this Guaranty prior to such expiration date, all of which claims shall expressly survive such expiration.

Guarantor waives the benefit of any statute of limitations affecting Guarantor’s liability under this Guaranty. This Guaranty shall be governed by and construed in accordance with the laws of the State of Maryland, without regard to the choice of law rules thereof. Guarantor hereby consents to the jurisdiction of any competent federal or state court located within the State of Maryland. Guarantor hereby waives trial by jury in any action brought on or with respect to this Guaranty. Guarantor agrees to pay all costs and expenses incurred by Sublandlord in enforcing this Guaranty, including, without limitation, all legal fees and disbursements.

IN WITNESS WHEREOF, the parties hereto have executed this Guaranty under Seal as of this 17^th day of July, 2012.
