NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged by Guarantor, Guarantor agrees as follows:

Section 1. Guaranty.

(a) Subject to Section 1(b) hereof, Guarantor hereby absolutely, irrevocably and
unconditionally guarantees the due and punctual payment and performance when due, whether at stated
maturity, by acceleration or otherwise, of the following (collectively referred to as the
“Guaranteed Obligations”): (1) all present and future indebtedness and obligations owing by
Borrower to any Lender or Administrative Agent under or in connection with the Credit Agreement and
any other Loan Document, including without limitation, the repayment of all principal of the Loans,
and the payment of all interest, Fees, charges, attorneys’ fees and other amounts payable to any
Lender or Administrative Agent thereunder or in connection therewith; (2) any and all extensions,
renewals, modifications, amendments or substitutions of the foregoing; (3) all expenses, including,
without limitation, attorneys’ fees and disbursements, that are incurred by Lenders and
Administrative Agent in the enforcement of any of the foregoing; and (4) all other Obligations,
provided, however, that the Guaranteed Obligations shall not include any obligation
of Borrower or any of its Subsidiaries under any Interest Rate Agreement.

(b) Notwithstanding anything contained in this Guaranty or any other Loan Document to the
contrary, the total liability of Guarantor hereunder in respect of the Guaranteed Obligations shall
not exceed an amount equal to fifty percent (50%) of the total amount of the Guaranteed Obligations
owed by Borrower to Administrative Agent and Lenders (the “Maximum Amount”) calculated at the time
demand for payment from Guarantor is made by Administrative Agent hereunder (the “Demand Date”),
subject to increase of the Guaranteed Obligations resulting from the application of Section 9
hereof.

(c) All expenses, including, without limitation, attorneys’ fees and disbursements that are
incurred by Lenders and Administrative Agent in the enforcement of the obligations of the Guarantor
hereunder, shall be fully recoverable from the Guarantor.

(d) All expenses, including, without limitation, attorneys’ fees and disbursements, that are
incurred by Lenders and Administrative Agent in connection with the Credit Agreement and any other
Loan Document following the Demand Date (collectively, “Post Demand Date Expenses”) shall be
recoverable from Guarantor; provided, however, total liability of Guarantor hereunder in respect of
the Post Demand Date Expenses shall not exceed an amount equal to fifty percent (50%) of the total
amount of Post Demand Date Expenses.

(e) Any amounts due from Guarantor to Administrative Agent or Lenders shall bear interest (i)
in the case of amounts payable pursuant to Section 1(a) hereof, from the Demand Date, and (ii) in
the case of amounts payable pursuant to Section 1(c) or (d) hereof, from the date that is thirty
(30) days after Administrative Agent’s demand therefor, and in the case of all of the foregoing
amounts, until such amounts are paid in full at the highest rate then applicable to the Guaranteed
Obligations.

(f) The Maximum Amount shall be applied to the Guaranteed Obligations as follows:

(i) Any payment by the Guarantor hereunder shall first be applied to reduce the aggregate
amount of any draws on account of any issued and outstanding LCs which remain unreimbursed on the
Demand Date.

(ii) Second, to the extent that any LCs remain outstanding on or after the Demand Date, then
Guarantor shall do one or more of the following in respect of any such LC: (A) deliver to
Administrative Agent cash collateral to secure the reimbursement obligations on account of such LC
plus the aggregate amount of Letter of Credit Fees which will be due on account of such outstanding
LC until the stated expiry date of such LC, (B) cause one or more back to back letter of credits to
be issued to Administrative Agent naming Administrative Agent as beneficiary thereof for and on
behalf of the Lenders, in an aggregate amount equal to the aggregate undrawn face amount of such
LC; or (C) cause such LC to be cancelled by the beneficiary thereof and returned to the applicable
LC Issuer. Guarantor shall be deemed to make a payment hereunder in an amount equal to the amount
of cash collateral delivered pursuant to clause (A) above, the face amount of each back to back
letter of credit delivered pursuant to clause (B) above and the aggregate undrawn face amount of
each LC cancelled and returned to the applicable LC Issuer pursuant to clause (C) above. To the
extent there are any draws under any LC or Letter of Credit Fees due thereon on or after the Demand
Date, Administrative Agent shall apply the cash collateral delivered pursuant to clause (A) above
to satisfy such reimbursement obligations or Letter of Credit Fees, and to the extent that any LC
in respect of which Guarantor delivers cash collateral pursuant to clause (A) above expires or is
cancelled (in whole or in part), then Administrative Agent shall return such cash collateral to
Guarantor (or in the case of a partial cancellation, the amount of such partial cancellation).

(iii) The remaining portion of the Maximum Amount, shall be applied to the Guaranteed
Obligations in the order and manner specified in the Credit Agreement.

Section 2. Guaranty of Payment and Not of Collection. This Guaranty is a guaranty of
payment, and not merely of collection. Accordingly, Lenders and Administrative Agent shall not be
obligated or required before enforcing this Guaranty against Guarantor: (a) to pursue any right or
remedy Lenders or Administrative Agent may have against Borrower or any other Person or commence
any suit or other proceeding against Borrower or any other Person in any court or other tribunal;
(b) to make any claim in a liquidation or bankruptcy of Borrower or any other Person; or (c) to
make demand of Borrower or any other Person or to enforce or seek to enforce or realize upon any
collateral security held by Lenders or Administrative Agent which may secure any of the Guaranteed
Obligations.

Section 3. Guaranty Absolute. Guarantor guarantees that the Guaranteed Obligations
will be paid strictly in accordance with the terms of the documents evidencing the same, regardless
of any Applicable Law now or hereafter in effect in any jurisdiction affecting any of such terms or
the rights of Administrative Agent or Lenders with respect thereto. The liability of Guarantor
under this Guaranty shall be absolute, irrevocable and unconditional in accordance with its terms
and shall remain in full force and effect without regard to, and shall not be released, suspended,
discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever,
including without limitation, the following (whether or not Guarantor consents thereto or has
notice thereof):

(a) Subject to the provisions of Section 4 of this Guaranty, (i) any change in the amount,
interest rate or due date or other term of any of the Guaranteed Obligations, (ii) any change in
the time, place or manner of payment of all or any portion of the Guaranteed Obligations, (iii) any
amendment or waiver of, or consent to the departure from or other indulgence with respect to, the
Credit Agreement, any other Loan Document, or any other document or instrument evidencing or
relating to any Guaranteed Obligations, 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 Credit
Agreement, any of the other Loan Documents, or any other documents, instruments or agreements
relating to the Guaranteed Obligations or any other instrument or agreement referred to therein or
evidencing any Guaranteed Obligations or any assignment or transfer of any of the foregoing;

(b) any lack of validity or enforceability of the Credit Agreement, any of the other Loan
Documents, or any other document, instrument or agreement referred to therein or evidencing any
Guaranteed Obligations or any assignment or transfer of any of the foregoing;

(c) any furnishing to Administrative Agent or Lenders of any additional security for the
Guaranteed Obligations, or any sale, exchange, release or surrender of, or realization on, any
security for the Guaranteed Obligations;

(d) any settlement or compromise of any of the Guaranteed Obligations, any security therefor,
or any liability of any other party with respect to the Guaranteed Obligations, or any
subordination of the payment of the Guaranteed Obligations to the payment of any other liability of
Borrower or any other obligor with respect to the Guaranteed Obligations;

(e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution,
liquidation or other like proceeding relating to Guarantor, Borrower or any other Person, or any
action taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such
proceeding;

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

(g) any nonperfection of any security interest or other Lien on any collateral securing in any
way any of the Guaranteed Obligations;

(h) any application of sums paid by Borrower or any other Person with respect to the
liabilities of Borrower to Administrative Agent or Lenders, regardless of what liabilities of
Borrower remain unpaid;

(i) any defect, limitation or insufficiency in the borrowing powers of Borrower or in the
exercise thereof; or

(j) any other circumstance which might otherwise constitute a defense available to, or a
discharge of, the Guarantor hereunder, including, without limitation, the failure by Administrative
Agent or any Lender to provide copies of any notice delivered to Borrower or any Subsidiary in
accordance with the terms of any of the Loan Documents.

Section 4. Action with Respect to Guaranteed Obligations.

(a) Subject to the provisions of Section 4(b) hereof, Lenders and Administrative Agent may, at
any time and from time to time, without the consent of, or notice to, Guarantor, and without
discharging Guarantor from its obligations hereunder, take any and all actions described in Section
3 hereof and may otherwise: (i) amend, modify, alter or supplement the Credit Agreement or any
other Loan Document; (ii) sell, exchange, release or otherwise deal with all, or any part, of any
collateral; (iii) release any Person liable in any manner for the payment or collection of the
Guaranteed Obligations; (iv) exercise, or refrain from exercising, any rights against Borrower or
any other Person; and (v) apply any sum, by whomsoever paid or however realized, to the Guaranteed
Obligations in such order as Lenders shall elect.

(b) Notwithstanding the foregoing, Administrative Agent and Lenders shall not agree to any of
the following without the prior written consent of the Guarantor: (i) any increase of the principal
amount of commitments under the Credit Agreement to an amount in excess of $500,000,000, (ii) any
increase in the interest rate applicable to the loans under the Credit Agreement (other than an
increase to the Default Rate in accordance with the terms of the Credit Agreement), (iii) any
amendment or modification that would have the effect of increasing the Default Rate, (iv) any
amendment or modification that would have the effect of modifying the Termination Date (otherwise
than pursuant to a termination of the Commitments pursuant to Section 2.12 or 10.2 of the Credit
Agreement), (v) any amendment or modification to Sections 10.1 or 10.2 of the Credit Agreement, or
(v) any amendment or modification that would have the effect of increasing any ratio or percentage
provided for in Section 7.12 of the Loan Agreement or the definition of Required Asset Quality
Level.

Section 5. Representations and Warranties. Guarantor hereby makes to Administrative
Agent and Lenders the following representations and warranties:

(a) Organization; Power; Qualification. Guarantor is a corporation, duly organized or
formed, validly existing and in good standing under the jurisdiction of its incorporation or
formation, has the power and authority to own or lease its respective properties and to carry, on
its respective business as now being and hereafter proposed to be conducted, and is duly qualified
and is in good standing as a foreign corporation, partnership, or other legal entity, and
authorized to do business, in each jurisdiction in which the character of its properties or the
nature of its business requires such qualification or authorization and where the failure to be so
qualified or authorized would have, in each instance, a Material Adverse Effect.

(b) Authorization. Guarantor has the right and power, and has taken all necessary
action to authorize it, to guaranty the Guaranteed Obligations hereunder. Guarantor has the right
and power, and has taken all necessary action to authorize it, to execute, deliver and perform this
Guaranty and any other Loan Document to which it is a party in accordance with their respective
terms and to consummate the transactions contemplated hereby and thereby. This Guaranty has been
duly executed and delivered by the duly authorized officers of the Guarantor, and each is a legal,
valid and binding obligation of the Guarantor, enforceable against it in accordance with its
respective terms.

(c) Compliance with Laws. The execution, delivery and performance of this Guaranty in
accordance with its terms do not and will not, by the passage of time, the giving of notice, or
otherwise: (i) require any Governmental Approval, other than such as have been obtained and are in
full force and effect, or violate any Applicable Law (including all Environmental Laws) relating to
the Guarantor; (ii) conflict with, result in a breach of, or constitute a default under the
articles of incorporation or bylaws of Guarantor or any indenture, agreement or other instrument to
which the Guarantor is a party or by which it or any of its properties may be bound; or (iii)
result in or require the creation or imposition of any Lien, other than Liens in favor of the
Administrative Agent and the Lenders, upon or with respect to any property now owned or acquired by
the Guarantor.

(d) Governmental Approvals. Guarantor is in compliance with each Governmental Approval
applicable to it and in compliance with all other Applicable Law relating to it (including, without
limitation, the Investment Company Act of 1940, as amended), except for non-compliances which, and
Governmental Approvals the failure to possess which, would not, individually or in the aggregate,
have a Material Adverse Effect.

(e) Defaults. No “Event of Default” or “Default” (as each such term is defined under
the Control Investor Credit Agreement) has occurred and is continuing or would exist after giving
effect to any of the Loan Documents.

Section 6. Covenants of Guarantor. For so long as this Agreement or the Credit
Agreement is in effect and thereafter until each of (x) the payment in full of the Obligations and
(y) the termination, expiration, or full cash collateralization of all LCs, Guarantor agrees as
follows:

(a) Year-End Statements. As soon as available and in any event within ninety-five (95)
days after the end of each fiscal year of Guarantor, Guarantor shall deliver to Administrative
Agent (with sufficient copies for distribution by Administrative Agent to each Lender for all
deliveries other than electronic deliveries) the financial statements of Guarantor as at the end of
such fiscal year which shall be (a) certified by the chief financial officer of Guarantor, in his
or her opinion, to present fairly, in accordance with GAAP, the financial position of Guarantor as
at the date thereof and the result of operations for such period and (b) examined and reported on
by independent certified public accountants meeting the requirements of Section 8.2 of the Control
Investor Credit Agreement, whose opinion shall be unqualified.

(b) Quarterly Financial Statements. As soon as available and in any event within fifty
(50) days after the close of each of the first, second, and third fiscal quarters of Guarantor,
Guarantor shall deliver to Administrative Agent (with sufficient copies for distribution by
Administrative Agent to each Lender for all deliveries other than electronic deliveries) the
financial statements of Guarantor as at the end of such period all of which shall be certified by
the chief financial officer of Guarantor, in his or her opinion, to present fairly, in accordance
with GAAP, the financial position of Guarantor as at the date thereof and the results of operations
for such period (subject to normal year-end audit adjustments).

(c) Additional Information. Guarantor shall contemporaneously deliver to
Administrative Agent (with sufficient copies for distribution by Administrative Agent to each
Lender for all deliveries other than electronic deliveries) copies of all documents required to be
delivered by the Guarantor to the lenders under the Control Investor Credit Agreement as provided
in Sections 8.3(a), 8.3(b)(i) and 8.4(a), (e) and (f) of the Control Investor Credit Agreement
notwithstanding termination of the Control Investor Credit Agreement.

(d) Compliance with Laws. Guarantor shall comply with all Applicable Laws (including,
without limitation, the Investment Company Act of 1940, as amended), including the obtaining and
maintaining of all Governmental Approvals, the failure with which to comply could reasonably be
expected to have a Material Adverse Effect.

(e) Business Development Company. Guarantor shall at all times maintain its status as
a “business development company” under the Investment Company Act of 1940, as amended.

Section 7. Waiver. Guarantor, to the fullest extent permitted by Applicable Law,
hereby waives notice of acceptance hereof or any presentment, demand, protest or notice of any kind
which in any manner or to any extent might vary the risk of Guarantor or which otherwise might
operate to discharge Guarantor from its obligations hereunder.

Section 8. Inability to Accelerate Loan. If Administrative Agent and/or Lenders are
prevented under Applicable Law or otherwise from demanding or accelerating payment of any of the
Guaranteed Obligations by reason of any automatic stay or otherwise, Agents and/or Lenders shall be
entitled to receive from the Guarantor, upon demand therefor, the sums which otherwise would have
been due had such demand or acceleration occurred.

Section 9. Reinstatement of Guaranteed Obligations. If claim is ever made on
Administrative Agent or any Lender for repayment or recovery of any amount or amounts received in
payment or on account of any of the Guaranteed Obligations, and Administrative Agent or such Lender
repays all or part of said amount by reason of (a) any judgment, decree or order of any court or
administrative body of competent jurisdiction, or (b) any settlement or compromise of any such
claim effected by such Administrative Agent or such Lender with any such claimant (including
Borrower or a trustee in bankruptcy for Borrower), then and in such event Guarantor agrees that any
such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any
revocation hereof or the cancellation of the Credit Agreement, any of the other Loan Documents, or
any other instrument evidencing any liability of Borrower, and Guarantor shall be and remain liable
to Administrative Agent or such Lender for the amounts so repaid or recovered to the same extent as
if such amount had never originally been paid to Administrative Agent or such Lender. Guarantor’s
liability under this Section 9 shall survive the termination of this Guaranty.

Section 10. Subrogation. Upon the making by Guarantor of any payment hereunder for the
account of Borrower, Guarantor shall be subrogated to the rights of the payee against Borrower;
provided, however, that Guarantor shall not enforce any right or receive any payment by way of
subrogation or otherwise take any action in respect of any other claim or cause of action Guarantor
may have against Borrower arising by reason of any payment or performance by Guarantor pursuant to
this Guaranty, unless and until all of the Guaranteed Obligations have been indefeasibly paid and
performed in full. If any amount shall be paid to Guarantor on account of or in respect of such
subrogation rights or other claims or causes of action, Guarantor shall hold such amount in trust
for the benefit of Administrative Agent and Lenders and shall forthwith pay such amount to
Administrative Agent to be credited and applied against the Guaranteed Obligations, whether matured
or unmatured, in accordance with the terms of the Credit Agreement or to be held by Administrative
Agent as collateral security for any Guaranteed Obligations existing.

Section 11. Set off.

(a) 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, Guarantor hereby authorizes each
Lender, at any time upon the occurrence and during the continuation of an Event of Default, without
any prior notice to Guarantor or to any other Person, any such notice being hereby expressly
waived, to set off and to appropriate and to apply any and all deposits (general or special,
including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured
or unmatured) and any other indebtedness at any time held or owing by any Lender, or an affiliate
of any Lender, to or for the credit or the account of Guarantor against and on account of any of
the Guaranteed Obligations, not to exceed the Maximum Amount, although such obligations shall be
contingent or unmatured. Each Lender agrees to give Guarantor prompt notice after the exercise by
Lender of such right of set off but the failure of a Lender to give such notice shall not affect
the validity of any such set off. Guarantor agrees, to the fullest extent permitted by Applicable
Law, that any Participant may exercise rights of set off or counterclaim and other rights with
respect to its participation as fully as if such Participant were a direct creditor of the
Guarantor in the amount of such participation.

(b) Administrative Agent and Lenders acknowledge and agree that the bank accounts set forth on
Schedule 11 attached hereto and any similar bank account created in the future shall not be subject
to any right of offset or banker’s lien.

Section 12 Information. Guarantor assumes all responsibility for being and keeping
itself informed of the financial condition of Borrower, and of all other circumstances bearing upon
the risk of nonpayment of any of the Guaranteed Obligations and the nature, scope and extent of the
risks that the Guarantor assumes and incurs hereunder, and agrees that neither Administrative Agent
nor any Lender shall have any duty whatsoever to advise Guarantor of information regarding such
circumstances or risks.

Section 13. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED, AND TO BE
FULLY PERFORMED, IN SUCH STATE, AND WITHOUT REFERENCE TO CONFLICT OF LAWS PRINCIPLES OR PROVISIONS.

Section 14. Jurisdiction; Consent to Service of Process: Waiver of Jury
Trial.

(a) Guarantor hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of any New York State court or Federal court of the United States of
America sitting in New York City, and any appellate court from any thereof; in any action or
proceeding arising out of or relating to this Guaranty or the other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or proceeding may be heard and
determined in such New York State court or, to the extent permitted by law, in such Federal court.
Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law. Nothing in this Guaranty shall affect any right that Administrative Agent
or any Lender may otherwise have to bring any action or proceeding relating to this Guaranty or the
other Loan Documents against Guarantor or its properties in the courts of any jurisdiction.

(b) Guarantor hereby irrevocably and unconditionally waives, to the fullest extent it may
legally and effectively do so, any objection which it may now or hereafter have to the laying of
venue of any suit, action or proceeding arising out of or relating to this Guaranty or the other
Loan Documents in any New York State court or Federal court located in the State of New York. Each
of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(c) Guarantor and each other party hereto consents to service of process in the manner
provided for notices in Section 21 hereof. Nothing in this Guaranty will affect the right of any
party to this Guaranty to serve process in any other manner permitted by law.

(d) Each party hereto hereby waives, to the fullest extent permitted by applicable law, any
right it may have to a trial by jury in respect of any litigation directly or indirectly arising
out of, under or in connection with this Guaranty or any of the other Loan Documents. Each party
hereto (1) certifies that no representative, agent or attorney of any other party has represented,
expressly or otherwise, that such other party would not, in the event of litigation, seek to
enforce the foregoing waiver and (2) acknowledges that it and the other parties hereto have been
induced to enter into this Guaranty and the other Loan Documents, as applicable, by, among other
things, the mutual waivers and certifications in this Section 14.

(e) Guarantor agrees not to assert any claim against Administrative Agent, any Lender, any of
their Affiliates, or any of their respective directors, officers, employees, attorneys, agents, and
advisers, on any theory of liability, for special, indirect, consequential, or punitive damages
arising out of or otherwise relating to this Guaranty or any of the other Loan Documents.

Section 15. Loan Accounts. Administrative Agent and each Lender may maintain books
and accounts setting forth the amounts of principal, interest and other sums paid and payable with
respect to the Guaranteed Obligations, and in the case of any dispute relating to any of the
outstanding amount, payment or receipt of any of the Guaranteed Obligation or otherwise, the
entries in such books and accounts shall be deemed prima facie evidence of the matters set forth
therein. The failure of Administrative Agent or any Lender to maintain such books and accounts
shall not in any way relieve or discharge Guarantor of any of its obligations hereunder.

Section 16. Waiver of Remedies. No delay or failure on the part of Administrative
Agent or any Lender in the exercise of any right or remedy it may have against any Guarantor
hereunder or otherwise shall operate as a waiver thereof, and no single or partial exercise by
Administrative Agent or any Lender of any such right or remedy shall preclude other or further
exercise thereof or the exercise of any other such right or remedy.

Section 17. Termination. This Guaranty shall remain in full force and effect until the
earlier of (i) indefeasible payment in full of the Guaranteed Obligations and the termination or
cancellation of the Commitments or (ii) indefeasible payment by Guarantor of the Maximum Amount and
of any amounts owing by Guarantor pursuant to Sections 1(c), 1(d) and 1(e) hereof.

Section 18. Successors and Assigns. Each reference herein to Administrative Agent or
Lenders shall be deemed to include such Person’s respective successors and assigns (including, but
not limited to, any holder of the Guaranteed Obligations) in whose favor the provisions of this
Guaranty also shall inure, and each reference herein to Guarantor shall be deemed to include
Guarantor’s successors and assigns, upon whom this Guaranty also shall be binding. Lenders may, in
accordance with the applicable provisions of the Credit Agreement, assign, transfer or sell any
Guaranteed Obligation, or grant or sell participations in any Guaranteed Obligations, to any Person
without the consent of, or notice to, Guarantor and without releasing, discharging or modifying
Guarantor’s obligations hereunder. Guarantor hereby consents to the delivery by the Agents or any
Lender to any Eligible Assignee or Participant (or any prospective Eligible Assignee or
Participant) of any financial or other information regarding Borrower or Guarantor. Guarantor may
not assign or transfer its rights or obligations hereunder or under any other Loan Document to any
Person without the prior written consent of all of Lenders (and any such assignment or transfer
without such consent shall be null and void).

Section 19. Amendments. This Guaranty may not be amended except in writing signed by
the Requisite Lenders (or all of Lenders if required under the terms of the Credit Agreement),
Administrative Agent and Guarantor.

Section 20. Payments. All payments to be made by Guarantor pursuant to this Guaranty
shall be made in Dollars, in immediately available funds to Administrative Agent at the Principal
Office.

Section 21. Notices. All notices and other communications required or provided for
hereunder shall be (a) in writing (including facsimile transmission or similar writing), (b) sent
in the case of Guarantor, to the address provided on the signature page to this Guaranty unless a
change of address has been sent to all other parties in accordance with the terms of this Section
21, or in the case of a notice to Administrative Agent or a Lender, to the address provided for in
the Credit Agreement and (c) all such notices and other communications shall be deemed effective
(i) if mailed, when received; (ii) if telecopied, when transmitted, or (iii) if hand delivered,
when delivered; provided, however, that any notice of a change of address for notices shall not be
effective until received.

Section 22. Severability. In case any provision of this Guaranty shall be invalid,
illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

Section 23. Headings. Section headings used in this Guaranty are for convenience only
and shall not affect the construction of this Guaranty.

Section 24. Definitions. Terms not otherwise defined herein are used herein with the
respective meanings given them in the Credit Agreement.

Section 25. No Novation. This Guaranty amends and entirely restates the Original
Guaranty executed by Guarantor; provided, however, that the execution and delivery of this Guaranty
and the other Loan Documents shall not in any circumstances be deemed to have terminated,
extinguished, or discharged the obligations and expenses under the Original Guaranty or the
collateral security therefor, all of which shall continue under and be governed by this Guaranty
and the other Loan Documents.

PLATO LEARNING, INC.

1993 Employee Stock Purchase Plan

(As Amended by the Second Amendment)

1. Purpose. The purpose of the 1993 Employee Stock Purchase Plan (the “Plan”) is to
provide employees of PLATO Learning Inc. (the “Company”) and its Subsidiary Companies (as
hereinafter defined in Section 14) with added incentive to continue in the employment of such
companies and to encourage increased efforts to promote the best interests of such companies by
permitting eligible employees to purchase shares of Common Stock of the Company, par value $.01 per
share (the “Stock”), at prices less than the then current market price thereof. The Plan is an
“employee stock purchase plan” under section 423 of the Internal Revenue Code of 1986, as amended
(the “Code”). The Company and its Subsidiary Companies are sometimes hereinafter called
collectively the “Participating Companies.”

2. Eligibility. Participation in the Plan shall be open to all active employees of the
Participating Companies whose customary employment is for more than 20 hours per week. No right to
purchase Stock shall accrue under the Plan in favor of any person who is not an eligible employee,
and no eligible employee shall acquire such right to purchase (i) if, immediately after receiving
such right, such employee would own 5% or more of the total combined voting power or value of all
classes of stock of the Company or any subsidiary corporation (as defined in section 425(f) of the
Code), taking into account in determining stock ownership any stock attributable to such employee
under section 425(d) of the Code; or (ii) which would permit such employee’s rights to purchase
stock under all employee stock purchase plans from time to time in effect of the Company and its
Subsidiary Companies to accrue at a rate which exceeds $25,000 of fair market value of such stock
for each calendar year, all determined in the manner provided by section 423(b)(8) of the Code.

3. Effective Date of Plan; Purchase Periods. The Plan shall become effective on such
date as may be specified by the Board of Directors (the “Board”) of the Company, provided that in
no event shall the Plan become effective unless within 12 months of the date of its adoption by the
Board it has been approved at a duly called meeting of the stockholders of the Company.

Purchases of Stock shall occur on the last day of each Purchase Period, which shall be the
last Monday of December, March, June and September (“Purchase Dates”). The first Purchase Period
shall commence on the date designated by the Board or a committee of directors not eligible to
participate in the Plan (the “Committee”) designated by the Board to administer the Plan and shall
end on the first Purchase Date thereafter. Each subsequent Purchase Period shall end on the
following Purchase Date. So long as the Plan remains in effect, a new Purchase Period shall
commence on the day immediately following the end of the preceding Purchase Period.

4. Basis of Participation. Employees who are eligible at the adoption of the Plan
shall be entitled to enroll in the Plan immediately. An employee who becomes eligible after the
adoption of the Plan shall be entitled to enroll in the Plan as of the first day of the month
commensurate with or following the month in which such employee shall first become eligible to
participate in the Plan. If an employee shall not enroll in the Plan as of the day he first
becomes eligible to enroll in the Plan, he shall be entitled to enroll in the Plan as of the first
day of any subsequent month within such Purchase Period. To enroll in the Plan, an eligible
employee shall execute and deliver a payroll deduction authorization card (the “Authorization”)
that shall become effective either upon adoption of the Plan or upon the first day of the month
commensurate or following the date on which such Authorization is delivered. Each Authorization
shall direct that payroll deductions be made by the Participating Company who is the employer of
the eligible employee enrolling in the Plan for each payroll period ending during the period while
such employee is a participant in the Plan. The amount of each payroll deduction specified in an
Authorization for each such payroll period shall be an amount specified by the employee greater
than or equal to $5. The total amount deducted in any one calendar year shall not exceed $21,250
(or such other amount that does not result in Purchases of Stock in excess of the limit set forth
in section 423(b)(8) of the Code).

Payroll deductions shall be made for each employee in accordance with his Authorization until
his participation in the Plan terminates, his Authorization is revised, or the Plan terminates, all
as hereinafter provided.

An employee may increase or decrease the amount of his payroll deductions each month by filing
an executed and revised Authorization with his employer. The increase or decrease shall take
effect as of the first day of the first full payroll period immediately following the delivery of a
revised Authorization. An employee may suspend payroll deductions at any time. Such suspension
shall not terminate the employee’s participation in the Plan and shall not affect his rights under
the Plan. The suspension shall take effect as of the first day of the first full payroll period
immediately following the delivery of a revised Authorization. Payroll deductions shall resume as
of the first day of the first full payroll period immediately following the delivery of a revised
Authorization. No other changes shall be permitted except that an employee may elect to terminate
his participation in the Plan as hereinafter provided.

Each participating employee’s payroll deductions shall be credited to his purchase account
under the Plan. Employees are not permitted to make lump sum contributions to purchase accounts
established on their behalf. On each Purchase Date, the amount in each purchase account will be
applied to the purchase of the number of whole shares of Stock determined by dividing (i) such
amount by (ii) the Purchase Price (as hereinafter defined) for such purchase period. Any remaining
amounts insufficient to purchase whole shares of stock will remain in the employee’s purchase
account and be applied toward the next purchase.

5. Purchase Price. The purchase price (the “Purchase Price”) per share of Stock
hereunder for any Purchase Period shall be 85% of the fair market value of a share of Stock on (a)
the beginning of the Purchase Period (or the date Authorization, if later there within), or (b) the
Purchase Date, whichever is lower; provided that if such percentage results in a fraction of one
cent, the Purchase Price shall be increased to the next higher full cent. The fair market value of
a share of Stock on the Purchase Date shall be deemed to be the closing price of the Stock on the
NASDAQ National Market System on such day, or if there shall be no such sale of the Stock on such
day, then on the next following business day on which there shall have been such a sale. In no
event, however, shall the Purchase Price be less than the par value of the Stock.

6. Issuance of Shares. The shares purchased on behalf of each eligible employee
participating in the Plan will be considered to be issued and outstanding to his credit as of the
close of business on the Purchase Date. As soon as practicable after each Purchase Date,
individual statements showing the number of shares of Stock purchased on that Purchase Date on
behalf of each participant will be delivered to each participant. Upon request, a participant may
receive a stock certificate for whole shares of Stock that are purchased on the Purchase Date. As
of the Purchase Date, those certificated shares of Stock will be issued to a nominee for the
benefit of the eligible employee. The certificated shares of Stock owned by each such employee
shall be held in an individual trust account established with an institutional trustee on behalf of
each participant. An employee may request that a stock certificate be issued to him evidencing the
number of shares of Stock purchased on his behalf under the Plan for which he has not previously
received a stock certificate, except that no certificate shall be issued for less than nine shares.
Notwithstanding the foregoing, an employee will be issued a certificate for his full shares when
the Plan is terminated. Certificates will not be issued for fractional shares. At such time as
the Plan is terminated, a cash payment will be made for the purchase by the Company of any
fractional share owned by an employee based upon the closing price of the Stock on the NASDAQ
National Market System on the date such termination takes effect, or if there shall be no such sale
of the Stock on such date, then on the next following business day on which there shall have been
such a sale.

No interest shall at any time accrue with respect to any amount credited to an employee’s
purchase account. After the close of each Purchase Period, a report will be made to each employee
participating in the Plan stating the entries made to his purchase account, the number of shares
purchased and the applicable Purchase Price.

7. [RESERVED]

8. Termination of Participation. An employee may at any time elect to terminate his
participation in the Plan, except that no such termination shall be effective as to any Purchase
Period unless such election is received by his employer in writing prior to the beginning of such
Purchase Period. An employee’s participation in the Plan shall terminate upon the earliest of (i)
his cessation of eligibility under the Plan, (ii) his termination of employment with the
Participating Companies, and (iii) his death. The cash credited on the date of such termination to
such an employee’s purchase account shall be returned to him or his legal representative promptly.
Any shares of Stock held for the benefit of such employee shall remain in the individual trust
account until he or his legal representative (i) instructs the trustee to sell the shares on his
behalf, or (ii) requests that certificates be issued in the manner described in Section 6 of this
Plan; provided however, that such shares shall not be issued or sold within six months of their
purchase unless the Plan is terminated prior to that time.

9. Termination or Amendment of the Plan. The Company, by action of the Board, or the
Committee may terminate the Plan at any time. Notice of termination shall be given to eligible
employees, but any failure to give such notice shall not impair the effectiveness of the
termination.

Without any action being required, the Plan will terminate in any event if the maximum number
of shares of Stock to be sold under the Plan (as hereinafter provided in Section 13) has been
purchased. If at any time the number of shares remaining available for purchase under the Plan are
not sufficient to satisfy all then outstanding purchase rights, the Board or the committee may
determine an equitable basis of apportioning available shares among all eligible employees on whose
behalf purchases would otherwise be made under the Plan.

The Board or the Committee may amend the Plan from time to time in any respect in order to
meet changes in legal requirements or for any other reason; provided, however, that
no such amendment shall (a) materially adversely affect any purchase rights outstanding under the
Plan during the Purchase Period in which such amendment is to be effected, (b) increase the maximum
number of shares of Stock which may be purchased under the Plan unless such an increase is approved
by the Company’s shareholders, (c) decrease the Purchase Price of the Stock for any purchase period
below 85% of the fair market value of the Stock on the Purchase Date or (d) adversely affect of the
Plan’s status as an employee stock purchase plan under section 423 of the Code.

Upon termination of the Plan, a stock certificate shall be issued to each eligible employee
participating in the Plan evidencing those whole shares of Stock held in his trust account, and the
amount credited to each eligible employee in his purchase account shall be distributed in cash,
along with a cash payment in lieu of fractional shares held in the eligible employee’s trust
account.

10. Non-Transferability. Rights acquired under the Plan are not transferable and may
be exercised only by an employee.

11. Stockholders’ Rights. No eligible employee shall by reason of the Plan have any
rights of a stockholder of the Company until and to the extent he shall be acquire shares of Stock
as herein provided.

12. Administration of the Plan. The Plan shall be administered so as to ensure that
all eligible employees participating in the Plan have the same rights and privileges as are
provided by section 423(b)(5) of the Code.

Members of the Committee may be appointed from time to time by the Board and shall be subject
to removal by the Board. The decision of a majority in number of the members of the Committee in
office at the time shall be deemed to be the decision of the Committee.

The Board or the Committee, from time to time, may approve the forms of any documents or
writings provided for in the Plan, may adopt, amend and rescind rules and regulations not
inconsistent with the Plan for carrying out the Plan and may construe the plan. The Board or the
Committee may delegate the responsibility for maintaining all or a portion of the records
pertaining to employees’ accounts to persons not affiliated with the Participating Companies. All
expenses of administering the Plan shall be paid by the Participating Companies, as determined by
the Committee.

13. Maximum Number of Shares. The maximum number of shares of Stock which may be
purchased under the Plan is 150,000, subject, however, to adjustment as hereinafter set forth.
Stock sold hereunder will be authorized and unissued shares. If, during the term of the Plan, the
Company shall effect a stock split or reverse stock split or other capital readjustment, the
payment of a stock dividend, or other increase receiving compensation therefor in money, services
or property, then: (1) in the event of an increase in the number of such shares outstanding, the
number of Common Shares then subject to purchase hereunder shall be proportionately increased, and
the cash consideration payable per share shall be proportionately reduced; and (2) in the event of
a reduction in the number of such shares outstanding, the number of Common Shares then subject to
purchase hereunder shall be proportionately reduced, and the cash consideration payable per share
shall be proportionately increased.

14. Miscellaneous. Except as otherwise expressly provided herein, any Authorization,
election, notice or document under the Plan from an eligible employee shall be delivered to his
employer and, subject to any limitations specified in the Plan, shall be effective when so
delivered.

The term “business day” shall mean any day that the NASDAQ National Market System is open for
business.

The term “Subsidiary Companies” shall mean all corporations which are subsidiary corporations
(within the meaning of section 425(f) of the Code) of which the Company is the common parent.

The masculine pronoun shall include the feminine.

The Plan, and the Company’s obligation to sell and deliver shares of Stock hereunder, shall be
subject to all applicable federal, state and foreign laws, rules and regulations, and to such
approval by any regulatory or governmental agency as may, in the opinion of counsel for the
Company, be required.
