I. Executive Summary

The Choice for Stockholders MANAGEMENT PROPOSAL THE COMPANY AND TICC MANAGEMENT, 1: TO APPROVE A NEW ADVISORY AGREEMENT LLC, TO TAKE EFFECT UPON A CHANGE BETWEEN OF CONTROL OF TICC MANAGEMENT, LLC Voting TICC/BSP (White): • Rewards a failed outgoing external manager • Places the future of TICC in the hands of an unproven manager • Very limited experience in the management of a BDC • Maintains commitment to an unstable dividend policy Voting TSLX (Gold): • Stops a value destructive transaction from going forward • Offers immediate premium value as well as increased liquidity • Sends a clear message to TICC to engage with the best offer on the table for stockholders • Gives TICC stockholders the potential to participate in TSLX value creation Voting NexPoint (Blue): • Does not deliver immediate upfront premium to stockholders¹• Puts TICC stockholder future in the hands of a manager with a failed history in the BDC sector THERE IS ONLY ONE CLEAR CHOICE THAT MAXIMIZES VALUE FOR STOCKHOLDERS ¹ i.e. no delivery of upfront consideration other than the prospect of lower fees going forward and the possibility of potential share buy-backs. 5

Why Stockholders Should Support TSLX’s Proposal • Unlike TSLX, TICC has consistently prioritized the external manager — The proposal recommended by the TICC Special Committee includes million payout to the outgoing TICC management team (through the purchase of an estimated $60 TICC’s payable to existing adviser, any external manager, as distinguished such as TICC’s adviser or from normal advisory fees that TSLX’s adviser, would be in the form of base management fees and incentive fees) that has underperformance since IPO, which the Special Committee has not overseen the dramatic refuted — TICC has merits of the TSLX proposal and rejected unilaterally denied stockholders TSLX’s non-binding offer without engaging in the opportunity to voice their opinion on the substantive dialogue or negotiations or conducting proper due diligence — TSLX has best in class fee structure and a commitment to repurchase stock • The TSLX manager that has proposal destroyed the value of the TICC stockholders’ would stop a payment to the underperforming investment TICC external • Unlike TICC, TSLX has a demonstrated capacity for paying a sustainable dividend • The TSLX in a leading platform that has consistently outperformed offer, if accepted as proposed, would enable TICC the sector stockholders to participate — TSLX would rotate TICC’s greater opportunity for stockholder return portfolio into higher performing assets and thus provide • Leading independent investment professionals agree that stockholders superior value TSLX offers TICC Source: Research analysts reports. 6

Issues for TICC Stockholders TICC has demonstrated a poor investment performance track record, coupled with decisions by its Board of Directors that are not in the stockholders’ best interests and are indicative of entrenchment ? TICC has delivered a total return of only 51.6% since its IPO, representing a 154.4% underperformance relative to the sector¹ ? TICC shares traded at 0.73x NAV on undisturbed basis as of Sept. 15th, the day immediately preceding the public Discount to announcement of the TSLX proposal NAV • Discount to NAV is indicative of market pessimism surrounding management’s ability to grow net asset value in light of poor track record ? NAV per share has declined in seven out of nine most recent quarters ? (14.2)% cumulative decline in NAV per share since Q1 2013 ? Under-earned dividend in three most recent quarters and likely would have under-earned dividend in previous quarters if not for an accounting error by TICC disclosed in Q1’2015 • Net Investment Income missed dividend by $(0.11) per share in Q2 2015 Unsustainable • Dividend coverage ratio has been 0.72x, 0.78x, and 0.62x in Q4’14, Q1’15 and Q2’15 respectively Dividend ? Under-earning of dividends has resulted in NAV erosion ? Annualized dividend yield of ~18.5% indicates market skepticism with respect to dividend sustainability ? Analysts covering TICC forecast material dividend cuts, citing current levels as unsustainable ? With a debt to equity ratio of 0.97x that is nearing the regulatory maximum, TICC has limited to no ability to raise Leverage additional capital Maxed Out ? Lack of access to capital minimizes ability to grow earning assets and dividends ? TICC has been unable to deliver material investment returns despite significant leverage levels ? Recommendation of Benefit Street Partners L.L.C. (“BSP”) acquisition of the TICC manager results in a $60 million transfer of value to the outgoing managers, as reported by Wells Fargo Research ? Lack of engagement with NexPoint Advisors L.P. (“NexPoint”) or with TSLX regarding their offer to acquire Board Actions TICC at a 20% premium is indicative of Board member entrenchment² ? The Special Committee of the Board of TICC sought a lower management fee from BSP only after they were compelled to do so following NexPoint’s public disclosure of its offer ? TICC’s independent directors have conflicts of interest with the TICC management team Source: Research reports, Public filings, SNL Note: Market data as of 15-Sep-2015, the day immediately preceding the public announcement of the TSLX proposal ¹ BDC sector peers comprise ACAS, AINV, ARCC, BKCC, FSC, GBDC, HTGC, MAIN, MCC, NMFC, PNNT, PSEC, SLRC, TCAP, and TCRD. Total return is defined as change in stock price plus any paid dividends over a given time period. ² For reference, the TSLX proposal represents a 12.8% discount to TICC’s NAV as of June 30, 2015, a narrower discount than the price at which the shares have traded since June 30th.

TSLX (NYSE) 8

Why Stockholders Should Not Support Other Alternatives • The BSP offer does not offer upfront premium to TICC stockholders • Instead the BSP offer compensates significant underperformance the outgoing external manager despite years of — The of value to estimated the external $60mm payment manager to representing 16% of TICC market cap the outgoing external manager represents a transfer based on the $6.28 September 15th share price.¹• independent, Investors should question given their deep connections with Chuck Royce whether TICC’s special committee to the Board is truly • BSP has very limited experience running a BDC • Finally, both BSP and NexPoint have a track record of significant underperformance – BSP taking return through Griffin Partners is only into account selling commissions and 1.4% dealer manager and has only $2.5mm fees² AUM before – Jul-2006, NexPoint vastly underperforming Credit Strategies (“NHF”) has credit and equity total return of only 19.4% benchmarks since inception in Source: Bloomberg Note: Total return is defined as change in stock price plus any paid dividends over a given time period. ¹ September 15th is the day immediately preceding the public announcement of the TSLX proposal ² BSP has additional AUM held in other vehicles, but to TSLX’s knowledge, no public information on such vehicles’’ performance. 9

Timeline of TSLX’s Engagement with TICC The Special Committee rejected TSLX’s proposal without engaging in any substantive dialogue (i.e. negotiations) with TSLX even after several attempts by TSLX to discuss the merits of TSLX’s offer ? The speed with which TICC reached a decision with respect to the TSLX offer suggests that the TICC Board did not meaningfully consider the benefits to stockholders of the TSLX proposal ? TICC rejected the TSLX offer within 12 hours after having received overview information about TSLX and seemingly without the benefit of a financial advisor ? TICC declined several offers made by TSLX for meetings to discuss the details and merits of its proposal ? Diligence information requests were minimal and largely consisted of requests for public financial information and an organizational overview of TSLX Initial Proposal Respond to Respond to Public Bid Info Request Info Request Announcement 10th Sep 11th Sep 12th Sep 13th Sep 14th Sep 15th Sep 16th Sep Cursory Follow up Offer Rejected Without Response Response Meaningful Dialogue ?

How Independent is TICC’s Special Committee of the Board? • TICC’s Board after the management renewed team the advisory agreement substantially underperformed against nearly with TICC management every every metric year even it should properly be entitled possible and, according to certain industry analysts, to given the composition charged of TICC’s portfolioą approximately 6x the fees • to BSP The Board could have considered once TICC Management informed terminating them that it was exiting the management contract and switching • Oxford management, Lane, another BDC paid fees and created whose adviser has the same managing assets under management for BSP member as through TICC purchases of their equity in CLOs managed by BSP — By life of these vehicles to TSLX’s calculation, TICC and Oxford Lane have or will pay millions in BSP fees over the • stockholders. A TICC’s Board has refused to utilize significant key reason may be it would reduce management share buybacks to fees and incentive fees create value for to management and certain TICC board members ¹ TICC Reiterates Rejection of TSLX’s offer, Wells Fargo, September 22, 2015 11

TICC’s Research Coverage Universe Research analysts who have the most neutral perspective overwhelming agree that the BSP offer is a bad deal for stockholders Analyst Commentary Support for BSP Offer ? “BSP offer provides no immediate compensation to TICC Wells Fargo Securities shareholders AND the value creation rests on a manager who ? has a [very limited] track record of managing a BDC” ? “We do not believe the proposal with BSP that is supported by Barclays TICC’s Board represents the best possible offer available to ? shareholders” ? “While TICC’s board of directors likely declined to engage with JMP Securities TSLX, TSLX expressed its full commitment to realize the value in ? the proposed transaction. We see value [in TSLX’s offer]” ? “Unfortunately, it is our belief that the Board is placing more value on the compensation that BSP is willing to provide to the management team to buy the contract than maximizing KBW shareholder values. If ultimately the Board pushes the BSP ? offer through, this is another black eye for the BDC industry regarding shareholder returns vs. management compensation” ? “In our view, the rejection of the TSLX offer calls into question of whose interests TICC’s Board is most concerned” Ladenburg Thalmann ? “We like the TSLX offer because it provides the clearest path yet ? to generating value for TICC shareholders” ? “We believe shareholders stand to gain more from BSP changing National Securities the company’s strategy than the quick gain of selling now at ? $7.50” Source: Research Reports, Public Filings ?

Analyst Commentary on Poor Governance at TICC KBW, Sept 16th “The $0.29 (TICC) dividend is not sustainable, and we expect it will be cut regardless of what happens. We have been talking about a dividend cut for over a year now…Now TSLX provides an interesting offer and the (TICC) Board rejects it without negotiating with TSLX. As the title of our note implies, we are questioning whether the (TICC) Board is really doing all they can to maximize shareholder value” Wells Fargo, Sept 22th “Unfortunately for TICC shareholders, as we examine TICC’s collateral (which is nearly void of real proprietary transactions), we find that investors have been paying nearly 6x the normal fee that should be charged on these large/liquid/BSL (broadly syndicated loan) type assets.” Wells Fargo, Sept 4th “We have no doubt that current shareholders will be quick to demand immediate compensation as opposed to intangibles promises that provide no benefit” TICC Largest Stockholder, Raging Capital Management, LLC letter to TICC Board, Sept 21th “Now, we want to ensure that the TICC Board is acting in accordance with its fiduciary obligations…We find ourselves at a critical juncture in TICC’s history where the Board’s decisions and actions over the next few weeks will have significant ramifications to stockholders” KBW, Aug 31st “We fail to see how the Board of directors at TICC can fulfill their legal fiduciary responsibility to TICC shareholders and not explore the potential for a transaction with an existing quality manager in the BDC sector” Barclays, Oct 6th “The board could have simply waited until the current advisory agreement came up for renewal. But instead, the board choose to go this route and support a proposal which pays out the current investment advisor” Source: Research Reports, Public Filings ? TSLX (NYSE) 13

TSLX’s Fees are Lower as a Portion of Total Economics ($ in millions) “Overall, the market does not look at expenses in a vacuum and neither should the TICC board.” – Wells Fargo Sept. 22 TICC Stockholders are Overpaying Fees ? BDC expenses must be examined relative to the collateral that each BDC manages • Proprietary credit work justifies higher fees whereas investing in CLO equity is much easier for a manager to do ? TICC’s collateral is very similar to the loan books of large mutual funds who charge 50bps • 96% of TICC’s collateral was offer by large bank desks – deals not proprietary • TICC average hold size of each tranche is 6.6% indicative of inability to dictate terms ? With an average expense ratio of 280bps over the last two years, TICC investors have been paying nearly 6x the fee charged by Levered Loan mutual funds with similar portfolio characteristics Economic Profit Compensation versus BDC Manager ? For stockholders, it is important to look at fees relative to the returns received by the stockholders ? Investors are generally less concerned with high fees as a percentage of assets if attractive returns are passed to the stockholder ?

Analyst and Shareholder Commentary Supporting TSLX’s Offer Cantor Fitzgerald, Sept 16th “TSLX trumped BSP’s offer, in our view, by presenting TICC’s board with a proposal that would provide a 20% premium to TICC shareholders”ą Wells Fargo, Sept 16th “Surprisingly, TICC’s special committee rejected TSLX’s offer… In our view, this rejection puts the board in a very tough predicament as the market may view this as a choice between paying substantial compensation to an underperforming external manager versus allowing TICC shareholders to receive an immediate return / premium” JMP Securities, Sept 17th “We believe the action taken by (TSLX) management highlights our favorable perception of the company’s leading governance practices and focus on creating shareholder value “ Ladenburg Thalmann, Sept 16th “As part of TPG, TICC shareholders would benefit from access to its broad platform including a direct origination team. Over the last year, TSLX has outperformed our BDC index by about 12% and (outperformed) TICC by about 24% on a total return basis” The Motley Fool, Sept 16th “I find TPG’s offer the most compelling, given that it provides an opportunity for TICC Capital investors to exit with an immediate return” Top 5 TICC Stockholder Muzinich & Co., Aug 31st (Pre-TSLX Offer) “We were surprised when the (TICC) Special Committee reaffirmed its initial position and, we believe, premature decision to pursue the BSP offer over competing offer. “ Source: Research Reports, Public Filings ¹ For reference, the TSLX proposal represents a 12.8% discount to TICC’s NAV as of June 30, 2015, a narrower discount than the price at which the shares have traded since June 30th. ?
