UNCONDITIONAL
GUARANTY OF PAYMENT AND PERFORMANCE


 


FOR AND IN CONSIDERATION OF the sum of
Ten and No/100 Dollars ($10.00) and other good and valuable consideration paid or delivered to the undersigned QTS REALTY TRUST, INC.,
a Maryland corporation (“REIT”), the receipt and sufficiency whereof are hereby acknowledged by REIT, and for the purpose
of seeking to induce KEYBANK NATIONAL ASSOCIATION, a national banking association (hereinafter referred to as “Lender”,
which term shall also include each other Lender which may now be or hereafter become a party to the Loan Agreement (as hereinafter
defined), and shall also include any such individual Lender acting as administrative agent for all of the Lenders), to extend credit
or otherwise provide financial accommodations to QualityTech, LP, a Delaware limited partnership ("Borrower"), under
the Loan Agreement, and seeking to induce the Lender Hedge Providers to provide financial accommodations by entering into derivative
contracts that may give rise to Hedge Obligations, which extension of credit and provision of financial accommodations will be
to the direct interest, advantage and benefit of REIT, REIT does, upon the occurrence of a Springing Recourse Event (as hereinafter
defined), hereby, absolutely, unconditionally and irrevocably guarantee to Lender and the Lender Hedge Providers the complete payment
and performance of the following liabilities, obligations and indebtedness of Borrower to Lender and the Lender Hedge Providers
(hereinafter referred to collectively as the “Obligations”) (capitalized terms that are used herein that are not otherwise
defined herein shall have the meanings set forth in the Loan Agreement):


 


(a)            the
full and prompt payment when due, whether by acceleration or otherwise, either before or after maturity thereof, of the Term Loan
Notes in the aggregate principal face amount of Two Hundred Fifty Million and No/100 Dollars ($250,000,000.00) made by Borrower
to the order of certain of the Lenders, which Term Loan Notes, are increasable to Five Hundred Million and No/100 Dollars ($500,000,000.00)
as provided in the Loan Agreement, together with interest as provided in the Term Loan Notes, and together with any replacements,
supplements, renewals, modifications, consolidations, restatements, increases and extensions thereof; and


 


(b)            the
full and prompt payment when due, whether by acceleration or otherwise, either before or after maturity thereof, of each other
note as may be issued under that certain Term Loan Agreement dated as of even date herewith (as amended, restated, supplemented,
or otherwise modified from time to time, the “Loan Agreement”) among Borrower, KeyBank, for itself and as administrative
agent, and the other lenders now or hereafter a party thereto, together with interest as provided in each such note, together with
any replacements, supplements, renewals, modifications, consolidations, restatements, increases, and extensions thereof (the Term
Loan Notes, and each of the notes described in this subparagraph (b) are hereinafter referred to collectively as the “Note”);
and


 


(c)            the
full and prompt payment and performance of any and all obligations of Borrower to Lender under the terms of the Loan Agreement,
together with any replacements, supplements, renewals, modifications, consolidations, restatements, and extensions thereof; and

    	 	1	 



     


    

 


(f)             the
full and prompt payment and performance of any and all other obligations of Borrower to Lender under any other agreements, documents
or instruments now or hereafter evidencing, securing or otherwise relating to the indebtedness evidenced by the Note or the Loan
Agreement (the Note, the Loan Agreement and said other agreements, documents and instruments are hereinafter collectively referred
to as the “Loan Documents” and individually referred to as a “Loan Document”). Without limiting the generality
of the foregoing, REIT acknowledges the terms of §2.11 of the Loan Agreement pursuant to which the Total Commitment under
the Loan Agreement may be increased to up to Five Hundred Million and No/100 Dollars ($500,000,000.00) and agree that this Unconditional
Guaranty of Payment and Performance (this “Guaranty”) shall extend and be applicable to each new or replacement note
delivered by Borrower in connection with any such increase of the Total Commitment and all other obligations of Borrower under
the Loan Documents as a result of such increase without notice to or consent from REIT.


 


Notwithstanding anything to the contrary
contained herein, under no circumstances shall any of the “Obligations” guaranteed hereby include any obligation that
constitutes an Excluded Hedge Obligation of REIT.


 


1.            Agreement
to Pay and Perform; Costs of Collection. Upon the occurrence of (a) REIT’s failure to perform any term, covenant
or agreement contained in §7.12 of the Loan Agreement (each, an "Asset Covenant Breach") and the passage of forty-five
days (45) after either (i) Borrower or REIT becomes aware of the Asset Covenant Breach, or (ii) Agent notifies Borrower
in writing of any Asset Covenant Breach, (b) if, at any time, REIT guarantees, or otherwise becomes obligated in respect of,
any Indebtedness (other than a conditional or springing guaranty on terms substantially similar to the Springing Guaranty or Indebtedness
permitted under §8.1(a), (b), (c), (d) or (f) of the Loan Agreement), (c) REIT (i) shall make an assignment
for the benefit of creditors, or admit in writing its general inability to pay or generally fail to pay its debts as they mature
or become due, or shall petition or apply for the appointment of a trustee or other custodian, liquidator or receiver for it or
any substantial part of its assets, (ii) shall commence any case or other proceeding relating to it under any bankruptcy,
reorganization, arrangement, insolvency, readjustment of debt, dissolution or liquidation or similar law of any jurisdiction, now
or hereafter in effect, or (iii) shall take any action to authorize or in furtherance of any of the foregoing, (d) a
petition or application shall be filed for the appointment of a trustee or other custodian, liquidator or receiver of REIT or any
substantial part of the REIT's assets, or a case or other proceeding shall be commenced against REIT under any bankruptcy, reorganization,
arrangement, insolvency, readjustment of debt, dissolution or liquidation or similar law of any jurisdiction, now or hereafter
in effect, and REIT shall indicate its approval thereof, consent thereto or acquiescence therein or such petition, application,
case or proceeding shall not have been dismissed within sixty (60) days following the filing or commencement thereof, (e) a
decree or order is entered appointing a trustee, custodian, liquidator or receiver for REIT or adjudicating REIT, bankrupt or insolvent,
or approving a petition in any such case or other proceeding, or a decree or order for relief is entered in respect of REIT in
an involuntary case under federal bankruptcy laws as now or hereafter constituted (each of 1(a), 1(b), 1(c), 1(d) and 1(e) of
this Guaranty being referred to a “Springing Recourse Event”), then REIT does hereby agree that following and during
the continuance of an Event of Default under the Loan Documents if the Note is not paid by Borrower in accordance with its terms,
or if any and all sums which are now or may hereafter become due from Borrower to Lender under the Loan Documents are not paid
by Borrower in accordance with their terms, or if any and all other obligations of Borrower to Lender under the Note or of Borrower
or any other Guarantor under the other Loan Documents are not performed by Borrower, or any other Guarantor, as applicable, in
accordance with their terms, REIT will immediately upon demand make such payments and perform such obligations. Upon the occurrence
of a Springing Recourse Event, REIT further agrees to pay Lender on demand all reasonable costs and expenses (including court costs
and reasonable attorneys’ fees and disbursements) paid or incurred by Lender in endeavoring to collect the Obligations guaranteed
hereby, to enforce any of the Obligations of Borrower guaranteed hereby, or any portion thereof, or to enforce this Guaranty, and
until paid to Lender, such sums shall bear interest at the Default Rate unless collection from REIT of interest at such rate would
be contrary to applicable law, in which event such sums shall bear interest at the highest rate which may be collected from REIT
under applicable law. REIT acknowledges and agrees that the Obligations guaranteed hereunder shall automatically become fully effective
upon a Springing Recourse Event and no other documentation shall be required to evidence same.


 






    	 	2	 



     


    

 


2.            Reinstatement
of Refunded Payments. If, for any reason, any payment to Lender of any of the Obligations guaranteed hereunder is required
to be refunded by Lender to Borrower, or paid or turned over to any other Person, including, without limitation, by reason of the
operation of bankruptcy, reorganization, receivership or insolvency laws or similar laws of general application relating to creditors’
rights and remedies now or hereafter enacted, REIT agrees to pay to the Lender on demand an amount equal to the amount so required
to be refunded, paid or turned over (the “Turnover Payment”), the obligations of REIT shall not be treated as having
been discharged by the original payment to Lender giving rise to the Turnover Payment, and this Guaranty shall be treated as having
remained in full force and effect for any such Turnover Payment so made by Lender, as well as for any amounts not theretofore paid
to Lender on account of such obligations.


 


3.            Actions
with Respect to Obligations. REIT hereby consents and agrees that Lender may at any time, and from time to time, without thereby
releasing REIT from any liability hereunder and without notice to or further consent from REIT or any other Person or entity, either
with or without consideration: release or surrender any lien or other security of any kind or nature whatsoever held by it or by
any Person, firm or corporation on its behalf or for its account, securing any indebtedness or liability hereby guaranteed; substitute
for any collateral so held by it, other collateral of like kind, or of any kind; modify the terms of the Note or the Loan Documents;
extend or renew the Note for any period; grant releases, compromises and indulgences with respect to the Note or the Loan Documents
and to any Persons or entities now or hereafter liable thereunder or hereunder; release any other Guarantor, surety, endorser or
accommodation party of the Note or any other Loan Documents; or take or fail to take any action of any type whatsoever. No such
action which Lender shall take or fail to take in connection with the Note or the Loan Documents, or any of them, or any security
for the payment of the indebtedness of Borrower to Lender or for the performance of any obligations or undertakings of Borrower,
REIT or other Guarantor, nor any course of dealing with Borrower or any other Person, shall release REIT’s obligations hereunder,
affect this Guaranty in any way or afford REIT any recourse against Lender. The provisions of this Guaranty shall extend and be
applicable to all replacements, supplements, renewals, amendments, extensions, consolidations, restatements and modifications of
the Note and the Loan Documents, and any and all references herein to the Note and the Loan Documents shall be deemed to include
any such replacements, supplements, renewals, extensions, amendments, consolidations, restatements or modifications thereof. Without
limiting the generality of the foregoing, REIT acknowledges the terms of §18.3 of the Loan Agreement and agrees that this
Guaranty shall extend and be applicable to each new or replacement note delivered by Borrower pursuant thereto without notice to
or further consent from REIT.


 






    	 	3	 



     


    

 


4.            No
Contest with Lender; Subordination. So long as any of the Obligations hereby guaranteed remain unpaid or undischarged or any
Lender has any obligation to make Loans, REIT will not, by paying any sum recoverable hereunder (whether or not demanded by Lender)
or by any means or on any other ground, claim any set-off or counterclaim against Borrower in respect of any liability of REIT
to Borrower or, in proceedings under federal bankruptcy law or insolvency proceedings of any nature, prove in competition with
Lender in respect of any payment hereunder or be entitled to have the benefit of any counterclaim or proof of claim or dividend
or payment by or on behalf of Borrower or the benefit of any other security for any of the Obligations hereby guaranteed which,
now or hereafter, Lender may hold or in which it may have any share. REIT hereby expressly waives any right of contribution from
or indemnity against Borrower or any other Guarantor, whether at law or in equity, arising from any payments made by REIT pursuant
to the terms of this Guaranty, and REIT acknowledges that REIT has no right whatsoever to proceed against Borrower or any other
Guarantor for reimbursement of any such payments. In connection with the foregoing, REIT expressly waives any and all rights of
subrogation to Lender against Borrower or any other Guarantor, and REIT hereby waives any rights to enforce any remedy which Lender
may have against Borrower or any other Guarantor and any rights to participate in any collateral for Borrower’s obligations
under the Loan Documents. REIT hereby subordinates any and all indebtedness of Borrower now or hereafter owed to REIT to all indebtedness
of Borrower or any other Guarantor to Lender, and agrees with Lender that (a) REIT shall not demand or accept any payment
from Borrower or any other Guarantor on account of such indebtedness, (b) REIT shall not claim any offset or other reduction
of REIT’s obligations hereunder because of any such indebtedness, and (c) REIT shall not take any action to obtain any
interest in any of the security, if any, described in and encumbered by the Loan Documents because of any such indebtedness; provided,
however, that, if Lender so requests, such indebtedness shall be collected, enforced and received by REIT as trustee for Lender
and be paid over to Lender on account of the indebtedness of Borrower to Lender, but without reducing or affecting in any manner
the liability of REIT under the other provisions of this Guaranty except to the extent the principal amount or other portion of
such outstanding indebtedness shall have been reduced by such payment.


 


5.            Waiver
of Defenses. REIT hereby agrees that its obligations hereunder shall not be affected or impaired by, and hereby waives and
agrees not to assert or take advantage of any defense based on:


 


(a)            (i) any
change in the amount, interest rate or due date or other term of any of the obligations hereby guaranteed, (ii) any change
in the time, place or manner of payment of all or any portion of the obligations hereby guaranteed, (iii) any amendment or
waiver of, or consent to the departure from or other indulgence with respect to, the Loan Agreement, any other Loan Document, or
any other document or instrument evidencing or relating to any obligations hereby guaranteed, or (iv) any waiver, renewal,
extension, addition, or supplement to, or deletion from, or any other action or inaction under or in respect of, the Loan Agreement,
any of the other Loan Documents, or any other documents, instruments or agreements relating to the obligations hereby guaranteed
or any other instrument or agreement referred to therein or evidencing any obligations hereby guaranteed or any assignment or transfer
of any of the foregoing;


 






    	 	4	 



     


    

 


(b)            any
subordination of the payment of the obligations hereby guaranteed to the payment of any other liability of Borrower, any other
Guarantor or any other Person;


 


(c)            any
act or failure to act by Borrower or any other Person which may adversely affect REIT’s subrogation rights, if any, against
Borrower, any other Guarantor or any other Person to recover payments made under this Guaranty;


 


(d)            nonperfection
or impairment of any security interest or other Lien on any collateral, if any, securing in any way any of the obligations hereby
guaranteed;


 


(e)            any
application of sums paid by Borrower or any other Person with respect to the liabilities of Lender, regardless of what liabilities
of Borrower remains unpaid;


 


(f)             any
defense of Borrower, including without limitation, the invalidity, illegality or unenforceability of any of the Obligations;


 


(g)            either
with or without notice to REIT, any renewal, extension, modification, amendment or other changes in the Obligations, including
but not limited to any material alteration of the terms of payment or performance of the Obligations;


 


(h)            any
statute of limitations in any action hereunder or for the collection of the Note or for the payment or performance of any obligation
hereby guaranteed;


 


(i)             the
incapacity, lack of authority, death or disability of Borrower or any other Person or entity, or the failure of Lender to file
or enforce a claim against the estate (either in administration, bankruptcy or in any other proceeding) of Borrower, REIT, any
other Guarantor or any other Person or entity;


 


(j)             the
dissolution or termination of existence of Borrower, REIT, any other Guarantor or any other Person or entity;


 


(k)            any
LLC Division of Borrower or any Guarantor;


 


(l)             the
voluntary or involuntary liquidation, sale or other disposition of all or substantially all of the assets of Borrower, REIT, any
other Guarantor or any other Person or entity;


 


(m)           the
voluntary or involuntary receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, assignment,
composition, or readjustment of, or any similar proceeding affecting, Borrower, REIT any other Guarantor or any other Person or
entity, or any of Borrower’s, REIT’s or any other Guarantor’s or any other Person’s or entity’s properties
or assets;


 


(n)            the
damage, destruction, condemnation, foreclosure or surrender of all or any part of the Real Estate or any of the improvements located
thereon;


 


(o)            the
failure of Lender to give notice of the existence, creation or incurring of any new or additional indebtedness or obligation of
Borrower or of any action or nonaction on the part of any other Person whomsoever in connection with any obligation hereby guaranteed;


 






    	 	5	 



     


    

 


(p)            any
failure or delay of Lender to commence an action against Borrower or any other Person, to assert or enforce any remedies against
Borrower under the Note or the other Loan Documents, or to realize upon any security;


 


(q)            any
failure of any duty on the part of Lender to disclose to REIT any facts it may now or hereafter know regarding Borrower (including,
without limitation Borrower’s financial condition), any other Guarantor or any other Person, any collateral, or any other
assets or liabilities of such Persons, whether such facts materially increase the risk to REIT or not (it being agreed that REIT
assumes responsibility for being informed with respect to such information);


 


(r)             failure
to accept or give notice of acceptance of this Guaranty by Lender;


 


(s)             failure
to make or give notice of presentment and demand for payment of any of the indebtedness or performance of any of the obligations
hereby guaranteed;


 


(t)             failure
to make or give protest and notice of dishonor or of default to REIT or to any other party with respect to the indebtedness or
performance of obligations hereby guaranteed;


 


(u)            any
and all other notices whatsoever to which REIT might otherwise be entitled;


 


(v)            any
lack of diligence by Lender in collection, protection or realization upon any collateral securing the payment of the indebtedness
or performance of obligations hereby guaranteed;


 


(w)           the
invalidity or unenforceability of the Note, or any of the other Loan Documents, or any assignment or transfer of the foregoing;


 


(x)             the
compromise, settlement, release or termination of any or all of the obligations of Borrower under the Note or the other Loan Documents
or the Hedge Obligations;


 


(y)            any
transfer by Borrower or any other Person of all or any part of the security, if any, encumbered by the Loan Documents;


 


(z)            the
failure of Lender to perfect any security or to extend or renew the perfection of any security; or


 


(aa)          to
the fullest extent permitted by law, any other legal, equitable or surety defenses whatsoever to which REIT might otherwise be
entitled, it being the intention that the obligations of REIT hereunder are absolute, unconditional and irrevocable.


 


REIT understands that the exercise by Lender
of certain rights and remedies may affect or eliminate Guarantor’s right of subrogation against Borrower or the other Guarantors
and that REIT may therefore incur partially or totally nonreimbursable liability hereunder. Nevertheless, REIT hereby authorizes
and empowers Lender, its successors, endorsees and assigns, to exercise in its or their sole discretion, any rights and remedies,
or any combination thereof, which may then be available, it being the purpose and intent of REIT that the obligations hereunder
shall, upon the occurrence of a Springing Recourse Event, be absolute, continuing, independent and unconditional under any and
all circumstances. Notwithstanding any other provision of this Guaranty to the contrary, REIT hereby waives and releases any claim
or other rights which REIT may now have or hereafter acquire against Borrower or any other Guarantor or other Person of all or
any of the obligations of REIT hereunder that arise from the existence or performance of REIT’s obligations under this Guaranty
or any of the other Loan Documents, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution
or indemnification, any right to participate in any claim or remedy of Lender against Borrower or any other Guarantor or other
Person or any collateral which Lender now has or hereafter acquires, whether or not such claim, remedy or right arises in equity
or under contract, statute or common law, by any payment made hereunder or otherwise, including, without limitation, the right
to take or receive from Borrower or any other Guarantor, directly or indirectly, in cash or other property or by setoff or in any
other manner, payment or security on account of such claim or other rights, except for those rights of other Guarantors under the
Contribution Agreement.


 






    	 	6	 



     


    

 


6.            Guaranty
of Payment and Performance and Not of Collection. This is a guaranty of payment and performance and not of collection. Upon
the occurrence of a Springing Recourse Event, the liability of REIT under this Guaranty shall be primary, direct and immediate
and not conditional or contingent upon the pursuit of any remedies against Borrower or any other Person, nor against securities
or liens available to Lender, its successors, successors in title, endorsees or assigns. REIT hereby waives any right to require
that an action be brought against Borrower or any other Person or to require that resort be had to any security or to any balance
of any deposit account or credit on the books of Lender in favor of Borrower or any other Person.


 


7.            Rights
and Remedies of Lender. In the event of an Event of Default under the Note or the Loan Documents, or any of them, that is continuing
(it being understood that the Lender has no obligation to accept cure after an Event of Default occurs), Lender shall have the
right to enforce its rights, powers and remedies thereunder or hereunder or under any other Loan Document, in any order, and all
rights, powers and remedies available to Lender in such event shall be nonexclusive and cumulative of all other rights, powers
and remedies provided thereunder or hereunder or by law or in equity. Accordingly, REIT hereby authorizes and empowers Lender upon
the occurrence and during the continuance of any Event of Default under the Note or the Loan Documents, at its sole discretion,
and without notice to REIT, to exercise any right or remedy which Lender may have, including, but not limited to, judicial foreclosure,
exercise of rights of power of sale, acceptance of a deed or assignment in lieu of foreclosure, appointment of a receiver to collect
rents and profits, exercise of remedies against personal property, or enforcement of any assignment of leases, as to any security,
whether real, personal or intangible. At any public or private sale of any security or collateral for any of the Obligations guaranteed
hereby, whether by foreclosure or otherwise, Lender may, in its discretion, purchase all or any part of such security or collateral
so sold or offered for sale for its own account and may apply against the amount bid therefor all or any part of the balance due
it pursuant to the terms of the Note or any other Loan Document without prejudice to Lender’s remedies hereunder against
REIT for deficiencies. If the Obligations guaranteed hereby are partially paid by reason of the election of Lender to pursue any
of the remedies available to Lender, or if such Obligations are otherwise partially paid, this Guaranty shall nevertheless remain
in full force and effect, and REIT shall, upon the occurrence of a Springing Recourse Event, remain liable for the entire balance
of the Obligations guaranteed hereby even though any rights which REIT may have against Borrower or any other Person may be destroyed
or diminished by the exercise of any such remedy.


 






    	 	7	 



     


    

 


8.            Application
of Payments. REIT hereby authorizes Lender, without notice to REIT, to apply all payments and credits received from Borrower,
REIT, any other Guarantor or any other Person or realized from any security in such manner and in such priority as Lender in its
sole judgment shall see fit to the Obligations.


 


9.            Business
Failure, Bankruptcy or Insolvency. In the event of the business failure of REIT or if there shall be pending any bankruptcy
or insolvency case or proceeding with respect to REIT under federal bankruptcy law or any other applicable law or in connection
with the insolvency of REIT, or if a liquidator, receiver, or trustee shall have been appointed for REIT or REIT’s properties
or assets, Lender may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have
the claims of Lender allowed in any proceedings relative to REIT, or any of REIT’s properties or assets, and, irrespective
of whether the indebtedness or other obligations of Borrower guaranteed hereby shall then be due and payable, by declaration or
otherwise, Lender shall be entitled and empowered to file and prove a claim for the whole amount of any sums or sums owing with
respect to the indebtedness or other obligations of Borrower guaranteed hereby, and to collect and receive any moneys or other
property payable or deliverable on any such claim. REIT covenants and agrees that upon the commencement of a voluntary or involuntary
bankruptcy proceeding by or against Borrower, REIT shall not seek a supplemental stay or otherwise pursuant to 11 U.S.C. §105
or any other provision of the Bankruptcy Code, as amended, or any other debtor relief law (whether statutory, common law, case
law, or otherwise) of any jurisdiction whatsoever, now or hereafter in effect, which may be or become applicable, to stay, interdict,
condition, reduce or inhibit the ability of Lender to enforce any rights of Lender against REIT by virtue of this Guaranty or otherwise.


 


10.          Covenants
of REIT. REIT hereby covenants and agrees with Lender that until all indebtedness guaranteed hereby has been completely repaid
and all obligations and undertakings of Borrower under, by reason of, or pursuant to the Note and the other Loan Documents have
been completely performed and Lender has no further obligation to make Loans, REIT will comply with any and all covenants applicable
to REIT set forth in the Loan Agreement.


 


11.          Rights
of Set-off. In addition to any rights now or hereafter granted under any of the other Loan Documents or applicable law and
not by way of limitation of any such rights, REIT hereby grants to Lender, during the continuance of any Event of Default under
the Note or the Loan Documents, at any time and without notice to REIT, the right to set-off and apply the whole or any portion
or portions of any or all deposits (general or specific, time or demand, provisional or final, regardless of currency, maturity,
or the branch of Lender where the deposits are held) now or hereafter held by Lender and other sums credited by or due from Lender
to REIT or subject to withdrawal by REIT against amounts payable under this Guaranty, whether or not any other person or persons
could also withdraw money therefrom. Any security now or hereafter held by or for REIT and provided by Borrower, or by anyone on
Borrower’s behalf, in respect of liabilities of REIT hereunder shall be held in trust for Lender as security for the liabilities
of REIT hereunder.


 


12.          Changes
in Writing; No Revocation. This Guaranty may not be changed orally, and no obligation of REIT can be released or waived by
Lender except as provided in §27 of the Loan Agreement. This Guaranty shall be irrevocable by REIT until all indebtedness
guaranteed hereby has been completely repaid and all obligations and undertakings of Borrower and REIT under, by reason of, or
pursuant to the Note and the other Loan Documents have been completely performed and the Lenders have no further obligation to
advance Loans under the Loan Agreement.
