Pursuant to the Transaction Agreement and subject to the satisfaction or waiver of certain conditions therein, LM Infra will acquire all of the assets of the Partnership through the following series of transactions: (a) LM DV Infra will acquire subsidiaries of REIT Subsidiary and REIT LLC (the “Equity Sale”), (b) REIT LLC will then merge with and into REIT Subsidiary, with REIT Subsidiary surviving the merger (the “First REIT Merger”), (c) REIT Subsidiary will then merge with and into the Partnership, with the Partnership surviving the merger (the “Second REIT Merger”), (d) Merger Sub II will then merge with and into the Partnership (the “First Partnership Merger”), with the Partnership surviving the First Partnership Merger and (e) the Partnership will then merge with and into Merger Sub (the “Second Partnership Merger” and, together with the Equity Sales, the First REIT Merger, Second REIT Merger and the First Partnership Merger, the “Transactions”), with Merger Sub surviving the Second Partnership Merger. As a result of the Transactions, the Common Units will be delisted from the NASDAQ Global Market.

Under the terms of the Transaction Agreement, at the effective time of the First Partnership Merger (the “First Partnership Merger Effective Time”), (a) each issued and outstanding common unit representing limited partner interests in the Partnership (“Common Units”), other than those Common Units owned by Landmark Dividend or its Affiliates (as defined below) (such Common Units, the “Landmark Dividend Common Units”), will be converted into the right to receive $16.50 per Common Unit in cash without any interest thereon (the “Partnership Unaffiliated Unitholders Consideration”); (b) each issued and outstanding Series A Preferred Unit (as defined in the Partnership Agreement) will be converted into the right to receive $25.00 plus the amount of any accumulated and unpaid distributions per Series A Preferred Unit in cash without any interest thereon; (c) each issued and outstanding Series B Preferred Unit (as defined in the Partnership Agreement) will be converted into the right to receive $25.00 plus the amount of any accumulated and unpaid distributions per Series B Preferred Unit in cash without any interest thereon and (d) each issued and outstanding Series C Preferred Unit (as defined in the Partnership Agreement) will be converted into the right to receive the greater of (1) $25.00 plus the amount of any accumulated and unpaid distributions per Series C Preferred Unit to, but not including, the date of the First Partnership Merger Effective Time plus the amount of any distributions that would have accrued from the date of the First Partnership Merger Effective Time to, but not including, the 50th Business Day following the First Partnership Merger Effective Time and (2) the sum of (i) the product of (x) the Alternative Conversion Amount (as defined in the Partnership Agreement) multiplied by (y) Partnership Unaffiliated

Pursuant to the Transaction Agreement and the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of April 2, 2018, as amended (the “Partnership Agreement”), holders of at least a majority of the issued and outstanding Common Units of the Partnership must affirmatively vote or consent in favor of the Transaction Agreement and the transactions contemplated thereby, including the Transactions, in order for them to be approved (“Partnership Unitholder Approval ”)Approval”). Pursuant to the terms of the Transaction Agreement, each of Landmark Dividend and the Buyer Parties agreed to vote all Common Units then owned beneficially or of record by it or any of its subsidiaries in favor of the approval of the Transaction Agreement and the Transactions and Landmark Dividend and each of the Buyer Parties agreed not to, and to cause each of their subsidiaries not to, directly or indirectly, transfer, assign or otherwise dispose of any Common Units owned by Landmark Dividend, such Buyer Party or its subsidiaries, other than to any of their respective Affiliates so long as such Affiliates agree to be bound by such obligations to the same extent as the Buyer Parties and Landmark Dividend. Accordingly, the Partnership expects that all such Common Units held by Landmark Dividend and each of the Buyer Parties will be voted in favor of the approval of the Transaction Agreement and the Transactions at the special meeting (the “Partnership Unitholder Meeting”) of holders (the “Partnership Unitholders”) of Common Units. The Partnership has scheduled the Partnership Unitholder Meeting to vote on the Transaction Agreement and the Transactions on ,December 9, 2021 at ,10:00 AM, Pacific Time, at .400 Continental Blvd., Suite 500, El Segundo, CA 90245. Regardless of the number of Common Units you own or whether you plan to attend the meeting, it is important that your Common Units be represented and voted at the meeting. Voting instructions are set forth inside this proxy statement.

A committee of the Board of Directors of the Partnership GP (the “Board”) consisting entirely of individuals that the Board determined satisfied the requirements set forth in the Partnership Agreement for service on a conflicts committee (the “Conflicts Committee”) has, by unanimous vote, in good faith, (a) determined that the Transaction Agreement and the consummation of the transactions contemplated thereby, including the Transactions, are in the best interests of the Partnership, including the holders of Common Units other than the Partnership GP and its Affiliates (including the Buyer Parties and their Affiliates) (such holders, the “Partnership Unaffiliated Unitholders”), (b) approved the Transaction Agreement and the transactions contemplated thereby, including the Transactions, which action constituted “Special Approval” as defined in the Partnership Agreement, and (c) recommended that the Board approve the Transaction Agreement, the execution, delivery and performance of the Transaction Agreement and the consummation of the transactions contemplated thereby, including the Transactions. The Conflicts Committee consists of independent directors Keith Benson, Thomas Carey White III and Gerald A. Tywoniuk.

The Board, after considering various factors, including the unanimous determination and recommendation of the Conflicts Committee, has determined that the Transaction Agreement and the transactions contemplated thereby, including the Transactions, are in the best interests of the Partnership and the Partnership Unaffiliated Unitholders and has approved the Transaction Agreement and the transactions contemplated thereby, including the Transactions. Accordingly, the Board recommends that the holders of all Common Units (the “Unitholders”) vote “FOR” the Transactions Proposal.

This proxy statement provides you with detailed information about the proposed Transactions and related matters. The Partnership encourages you to read the entire document carefully. You may also obtain additional information about the Partnership from documents the Partnership has filed with the Securities and Exchange Commission.

THE TRANSACTIONS

This discussion of the Transactions is qualified in its entirety by reference to the Transaction Agreement, a copy of which is attached to this proxy statement as Annex A and incorporated into this proxy statement by reference. You should read carefully the Transaction Agreement in its entirety because it, and not this proxy statement, is the legal document that governs the terms of the Transactions, including the First Partnership Merger and the Second Partnership Merger.

The Partnership is a limited partnership formed under Delaware law, and the Partnership GP serves as the general partner of the Partnership. The Board of the Partnership GP oversees the management of the Partnership, and unlike a corporation, the duties that the Partnership GP and its board members owe to the Partnership are determined solely by the terms of the Partnership Agreement and not by the fiduciary duties that are required by directors of a corporation. Under the Partnership Agreement, the standard of required conduct by the general partner is to make determinations and take actions in good faith (as defined in the Partnership Agreement), and the Partnership Agreement contains a broad waiver of any fiduciary duties. The general partner has an option, but not an obligation, under the Partnership Agreement to refer any matter that might constitute a potential conflict of interest to the Conflicts Committee, and, if the Conflicts Committee approves the matter, then approval shall be deemed to have been in good faith. The Board elected its option to refer the negotiation of the Transactions to the Conflicts Committee because of the conflict of interest, and the Conflicts Committee negotiated and approved the terms of the Transactions. The Partnership GP did not grant authority to the Conflicts Committee to negotiate the sale of the Partnership to a third party as the Partnership GP is not considering pursuing a third party sale and under the terms of the Partnership Agreement, the Partnership GP has no duty to pursue any sale of its interests in the Partnership.

Background of the Transactions

On May 15, 2021, Digital LD Management / Non-REIT Holdings, LP, an affiliate of the Buyer Parties (together with its affiliates, “DigitalBridge”) entered into a Purchase and Sale Agreement (the “PSA”) with Landmark Dividend Holdings II LLC, an affiliate of Landmark Dividend, providing for the acquisition (the “Sponsor Acquisition”) of Landmark Dividend and the Landmark Dividend Common Units from affiliates of American Infrastructure Funds LLC. From the initial public offering of the Partnership in 2014 until the Sponsor Acquisition, the Partnership GP and Landmark Dividend had been controlled by affiliates of American Infrastructure Funds LLC.

Prior to entering into the PSA with DigitalBridge, Landmark Dividend entered into customary non-disclosure agreements with potential acquirers of Landmark Dividend, pursuant to which such counterparties agreed to customary standstill provisions restricting their ability to purchase units of the Partnership.

Prior to the closing of the Sponsor Acquisition, on May 17, 2021, DigitalBridge informed the Board and issued a press release of its intent to submit a proposal to acquire all of the outstanding limited partner interests of the Partnership that were not already owned by DigitalBridge for cash consideration of $13.00 per Common Unit.

On May 18, 2021, in light of the publicly announced acquisition of the Partnership GP by DigitalBridge and DigitalBridge’s publicly announced intent to submit a proposal to acquire all of the outstanding limited partner interests of the Partnership that were not already owned by DigitalBridge, the independent members of the Board held an initial meeting to discuss expected key workstreams with respect to a potential proposal from the DigitalBridge.

In late May 2021, the independent members of the Board interviewed potential legal counsels and selected Gibson, Dunn & Crutcher LLP (“Gibson Dunn”) as its legal counsel with respect to a potential proposal from DigitalBridge.

In late May and early June 2021, the independent members of the Board interviewed potential financial advisors and selected Evercore as its financial advisor with respect to a potential proposal from DigitalBridge.

Upon closing of the Sponsor Acquisition on June 2, 2021, DigitalBridge acquired control of the Partnership GP and the Partnership. On the same day, DigitalBridge submitted to the Board a written letter proposing to acquire all of the outstanding limited partner interests of the Partnership that were not already owned by DigitalBridge for cash consideration of $13.00 per Common Unit (the “Sponsor Proposal”).

On June 3, 2021, the independent members of the Board met with Gibson Dunn to discuss the written proposal letter submitted by DigitalBridge regarding the Sponsor Proposal.

On June 8, 2021, the independent members of the Board met with the remaining members of the Board and the Management regarding the Sponsor Proposal. Later that day, the independent members of the Board met with Gibson Dunn to discuss the Sponsor Proposal.

On July 1, 2021, the Conflicts Committee met with representatives of Gibson Dunn, Evercore, DigitalBridge and Landmark Dividend. The Management presented to the Conflicts Committee the business plan prepared by Landmark Dividend, which included preliminary financial projections for the Partnership, in connection with the Conflicts Committee’s review, consideration and evaluation of the Sponsor Proposal.

On July 2, 2021, the Conflicts Committee met with representatives of Gibson Dunn and Evercore to discuss the business plan presented by the Management on the day before.

On July 16, 2021, Verde Investments, Inc. (“Verde”) submitted a written letter to the Board proposing to acquire all of the outstanding limited partner interests of the Partnership that were not already owned by Verde for cash consideration of $13.50 per Common Unit (the “Verde Proposal”).

Later that day, Gibson Dunn had a call with Simpson regarding interactions among the Management, Verde, Simpson, and legal counsel to Verde. Simpson stated, on behalf of DigitalBridge and the Partnership GP, that the Conflicts Committee was not authorized, and would not be authorized, by the Board to engage with Verde and the Partnership GP would not consider any third party offers, including the Verde Proposal. Gibson Dunn

On July 30, 2021, the Conflicts Committee met with representatives of Gibson Dunn and Evercore to discuss updated preliminary discussion materials prepared by Evercore evaluating the Sponsor Proposal based on additional data provided by DigitalBridge.

On August 2, 2021, the Conflicts Committee met with representatives of Gibson Dunn and Evercore to discuss the further updated discussion materials prepared by Evercore evaluating the Sponsor Proposal based on

additional information provided by Management. After such discussion, the Conflicts Committee members unanimously agreed to make a counterproposal of $16.50 cash per Common Unit not already owned by DigitalBridge, with such counterproposal being subject to completion of certain tax analyses requested by the Conflicts Committee to be provided by DigitalBridge and negotiation of definitive transaction documents (the “Counterproposal”). The Conflicts Committee directed Evercore to deliver the Counterproposal orally to DigitalBridge’s financial advisor, TAP Advisors (“TAP”), which Evercore did on August 3, 2021.

On August 3, 2021, Melody Investment Advisors LP (“Melody”) delivered to the Partnership GP and publicly disclosed a letter addressed to the Conflicts Committee proposing the purchase by Melody of 100% of the assets currently owned by the Partnership through one or a series of transactions that would result in holders of the Partnership’s Common Units receiving $16.25 per Common Unit in cash (the “Melody Proposal”).

On August 8, 2021, the Conflicts Committee met with representatives of Gibson Dunn, Evercore and Potter Anderson. Evercore reported on the discussion with TAP, and Gibson Dunn reported on its call with Simpson. After a lengthy discussion, the Conflicts Committee agreed that Evercore and Gibson Dunn should deliver oral responses to TAP and Simpson, respectively, that the Conflicts Committee reaffirmed its Counterproposal and would engage in negotiations of transaction documents if DigitalBridge were to agree to the terms of the Counterproposal, but would not make a final decision or grant any approvals at that time. Evercore and Gibson Dunn conveyed such message to TAP and Simpson, respectively, later that day.

On August 13, 2021, a company that provides communications infrastructure services (“Party A”) submitted a letter addressed to the Conflicts Committee proposing the purchase by Party A of 100% of the wireless communications assets currently owned by the Partnership for a purchase price of $550 million in cash (the “Party A Proposal”).

On August 13, 2021, Simpson sent an initial draft of the Transaction Agreement to Gibson Dunn. The terms set forth in the draft Transaction Agreement included, among other things: (i) merger consideration of $16.50

Transaction Agreement for certain limited purposes; (ii) adding back the Intervening Event limitation for a Partnership Adverse Recommendation Change, which no longer specifically excluded acquisition proposals; (iii) adding back the provision specifying that a Partnership Adverse Recommendation Change would not affect the validity of Special Approval granted by the Conflicts Committee; (iv) deletion of standstill provisions; and (v) deletion of the requirement for approval of the Transaction Agreement and the Transactions by the holders of a majority of the outstanding Common Units excluding Common Units owned by DigitalBridge.

On August 19, 2021, the Conflicts Committee met with representatives of Gibson Dunn, Evercore and Potter Anderson to discuss the revised draft Transaction Agreement, and the Conflicts Committee directed Gibson Dunn pursue certain further changes to the draft Transaction Agreement, including to clarify that Intervening Event would be defined to include alternative proposals, to delete the provision specifying that a Partnership Adverse Recommendation Change provision would not affect the validity of Special Approval granted by the Conflicts Committee, and to reinsert the standstill provisions applicable to the Buyer Parties. Following the meeting, Gibson Dunn had a call with Simpson to discuss the draft Transaction Agreement,

the Transaction Agreement, the execution, delivery and performance of the Transaction Agreement, and the consummation of the transactions contemplated thereby, including the Transactions.

Later in the afternoon on August 21, 2021, at a telephonic meeting of the Board, the Board (a) determined that the Transaction Agreement and the transactions contemplated thereby, including the Transactions, are in the best interests of the Partnership and the Partnership Unaffiliated Unitholders, (b) approved the Transaction Agreement, the execution, delivery and performance of the Transaction Agreement and the consummation of the transactions contemplated thereby, including the Transactions, (c) resolved to submit the Transaction Agreement to a vote of the Unitholders and (d) recommended approval of the Transaction Agreement, including the Transactions, by the Unitholders.

Thereafter, on August 21, 2021, the Buyer Parties delivered to the Partnership Parties the executed Debt Commitment Letter and Equity Commitment Letter, and the parties executed the Transaction Agreement.

On September 8, 2021, the Board held a meeting to discuss the Revised Melody Proposal. During the meeting, DigitalBridge explained that Landmark Dividend believed Melody was a direct competitor whose proposal was not actionable for a variety of reasons including because such proposal fails to value Landmark Dividend’s controlling general partner interest and incentive distribution rights andprimarily because Landmark Dividend is not evaluating third party offers. The Conflicts Committee again requested authority to engage with Melody, and DigitalBridge and the Partnership GP rejected such request.request because Landmark Dividend is not considering third party offers. The Conflicts Committee also requested that the Partnership GP request valuation materials and other information from Melody, and DigitalBridge and the Partnership GP rejected such request. DigitalBridge confirmed that if the Transactions were not successful, Landmark Dividend intended for the Partnership to continue as a publicly traded limited partnership. Later that afternoon, the Conflicts Committee met with representatives of Gibson Dunn, Evercore and Potter Anderson to discuss the meeting with DigitalBridge.

As part of its deliberative process, the Conflicts Committee considered the following factors to be generally negative or unfavorable in making its determination and grant of Special Approval, and the related recommendation to the Board:

TheIn light of (i) Landmark Dividend’s ownership of the Partnership GP and its right to appoint all of the members of the Partnership GP board of directors, (ii) Partnership GP’s right to make decisions in its individual capacity free of any duties to the Partnership or its unitholders, (iii) the Conflicts Committee’s authority to consider and negotiate only the Sponsor Proposal and not alternative proposals received by the Partnership and (iv) DigitalBridge and Partnership GP’s stated intention to either acquire the Partnership or maintain the status quo and not pursue a sale of the Partnership or its assets to a third party, the Conflicts Committee also considered the following factors relating to the procedural safeguards that the Conflicts Committee believed were and are present to ensure the fairness of the Transactions and the Transaction Agreement and to permit the Conflicts Committee to make its determination and grant Special Approval, and the related recommendation to the Board, which the Conflicts Committee believes support its decision and provide assurance as to the procedural fairness of the Transactions and the Transaction Agreement to the Partnership Unaffiliated Unitholders:

and the terms and conditions of the Transactions and any agreements and arrangements related thereto on behalf of the Partnership and the Partnership Unaffiliated Unitholders, (b) negotiate the terms and any documentation of the Transactions and related agreements directly with each of DigitalBridge and its affiliates and/or the Partnership’s management and the counsel and advisors to each of them, as it deemed necessary, appropriate or advisable, in its sole discretion, (c) consult with, advise and/or direct management of the Partnership in connection with discussions and/or negotiations concerning potential terms and conditions of the Transactions and related agreements, (d) determine whether the Transactions and related agreements were in the best interests of the Partnership, (e) determine whether to recommend that the Board approve or not approve, as applicable, the Transactions and related agreements, with any such approval and related recommendation of the Conflicts Committee constituting “Special Approval” for all purposes under the Partnership Agreement, including Section 7.9(b) thereof, with respect to the Transactions and related agreements and (f) make a recommendation to the Board whether it should (i) approve the Transactions and related agreements and (ii) recommend the Transactions to the Partnership Unaffiliated Unitholders, with the Board, acting for and on behalf of the Partnership GP in its capacity as the general partner of the Partnership, ultimately making a determination to approve or not approve the Transactions and agreements on behalf of the Partnership.

By vote at a meeting of the Conflicts Committee on August 21, 2021, the Conflicts Committee unanimously (a) determined that the Transaction Agreement and the transactions contemplated thereby, including the Transactions, are in the best interests of the Partnership, including the Partnership Unaffiliated Unitholders, (b) approved the Transaction Agreement and the transactions contemplated thereby, including the Transactions, such approval constituting “Special Approval” of the Transaction Agreement and the transactions contemplated thereby, including the Transactions, for all purposes under the Partnership Agreement, and (c) recommended that the Board approve the Transaction Agreement, the execution, delivery and performance of the Transaction Agreement, and the consummation of the transactions contemplated thereby, including the Transactions. In evaluating the Transaction Agreement and the transactions contemplated thereby, the Conflicts Committee considered information supplied by DigitalBridge and Management, consulted with its legal and financial

The Board believes that the Transactions are substantively and procedurally fair to the holders of Preferred Units, as Preferred Units will be entitled to receive in the Transaction the exact consideration the holders of such Preferred Units would have received had they instead been redeemed rather than cashed out in the Transaction. For additional information, see “The Transaction Agreement—The Transactions Consideration.”

Other than its review and adoption of the analysis of the Conflicts Committee, the Board did not conduct a going-concern valuation of the Partnership in evaluating the Transactions because of its belief that the financial analyses presented by Evercore to the Conflicts Committee, as more fully summarized below in the section entitled “Opinion of Evercore Group L.L.C.—Financial Advisor to the Conflicts Committee,” represented potential valuations of the Partnership as it continues to operate its business as a going concern. The Board did not consider net book value, which is an accounting concept, for purposes making its recommendation, because, in the Board’s view, net book value is indicative of neither the Partnership’s market value nor its value as a going concern, but rather is an indicator of historical costs. In the course of reaching its decision to recommend to the Unitholders that they approve the Transaction Agreement and the Transactions, the Board did not consider the liquidation value of the Partnership because it considered the Partnership to be a viable, going concern and therefore did not consider liquidation value to be a relevant methodology.

The foregoing discussion is not intended to be exhaustive, but is intended to address the material information and principal factors considered by the Board in considering the Transactions. In view of the various factors and information considered, the Board did not find it practicable to, and did not make specific assessments of, quantify or otherwise assign relative weights to, the specific factors considered in reaching its determination. In addition, the Board did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was determinative of its ultimate determination, and individual members of the Board may have given different weights to different factors. The Board made its recommendation based on the totality of information presented to, and the investigation conducted by, the Board. It should be noted that certain statements and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements.”

The Board recommends that the Unitholders vote “FOR” the approval of the Transactions Proposal.

Unaudited Financial Projections of the Partnership

The Partnership does not, as a matter of course, publicly disclose long-term financial projections because of, among other reasons, the uncertainty of the underlying assumptions and estimates and the unpredictability of its business and competitive markets in which it operates. While the Partnership prepares forecasts annually for internal budgeting and business planning purposes, such forecasts generally focus on the current fiscal year and the immediately following fiscal year.

The summary financial projections included in this proxy statement should not be regarded as predictive of actual future results nor should they be construed as financial guidance. The summary of the financial projections is not intended to influence or induce any Unitholder to vote in favor of the Transactions Proposal but has been included solely because these financial projections were made available to the Conflicts Committee and used by Evercore in connection with the rendering of its fairness opinion to the Conflicts Committee and performing its related financial analyses, as described in the section entitled “—Opinion of Evercore Group L.L.C. Financial Advisor to the Conflicts Committee.”

The Partnership’s financial projections are subjective in many respects. There can be no assurance that these financial projections will be realized or that actual results will not be significantly higher or lower than forecasted. In addition, the financial projections were not prepared with a view toward public disclosure or toward complying with generally accepted accounting principles in the United States (“GAAP”), the published guidelines of the SEC regarding projections or the use of non-GAAP financial measures or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The prospective financial information included in this proxy statement has been prepared by, and is the responsibility of, the Partnership’s management. No Independent Registered Public Accounting Firm has either audited, reviewed, examined, compiled or applied agreed-upon procedures with respect to the accompanying prospective financial information and the Report of Independent Registered Public Accounting Firm incorporated by reference in this proxy statement relates to the Partnership’s historical financial information. It does not extend to the prospective financial information and should not be construed to express an opinion or any other form of assurance with respect thereto.

In developing the financial projections for the years 2021 through 2026, the Partnership made numerous material assumptions with respect to its business for the periods covered by the projections. The Partnership developed a management case (the “Management Case”) of financial projections, and the Management Case assumptions included, but were not limited to, the following:

Important factors that may affect actual results and cause these financial projections not to be achieved include, but are not limited to, risks and uncertainties relating to the Partnership’s business (including the Partnership’s ability to achieve strategic goals, objectives and targets over the applicable periods), industry performance, general business and economic conditions, the regulatory environment and other factors described in or referenced under “Cautionary Statement Regarding Forward-Looking Statements” and those risks and uncertainties detailed in the Partnership’s public filings with the SEC. In addition, the projections also reflect assumptions that are subject to change and do not reflect revised prospects for the Partnership’s business,

Management Case

LMRK – Summary Financials 5-Year Forecast

Non-GAAP Financial Measures

The Partnership defines EBITDA as net income before interest, income taxes, depreciation and amortization, and defines Adjusted EBITDA as EBITDA before impairments, acquisition-related expenses, unrealized and realized gains and losses on derivatives, loss on extinguishment of debt, gains and losses on sale of real property interests, unit-based compensation, straight line rental adjustments, amortization of above- and below-market rents plus cash receipts applied toward the repayments of investments in receivable, the deemed capital contribution to fund the Partnership’s general and administrative expense reimbursement and adjustments for investments in unconsolidated joint ventures.

EBITDA and Adjusted EBITDA are non-GAAP supplemental financial measures that management and external users of the Partnership’s financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:

The Partnership believes that the presentation of EBITDA and Adjusted EBITDA in these financial projections provide useful information in assessing the Partnership’s financial condition and results of operations. The GAAP measures most directly comparable to EBITDA and Adjusted EBITDA are net income and net cash provided by operating activities. EBITDA and Adjusted EBITDA should not be considered as an alternative to GAAP net income, net cash provided by operating activities or any other measure of financial performance or

Opinion of Evercore Group L.L.C.—Financial Advisor to the Conflicts Committee

The Conflicts Committee retained Evercore as its financial advisor with respect to the provision of (i) financial advisory services and (ii) an opinion to the Conflicts Committee as to the fairness from a financial point of view to the Partnership Unaffiliated Common Unitholders of the merger consideration to be received by the Partnership Unaffiliated Common Unitholders in the First Partnership Merger. At the request of the Conflicts Committee at its meeting held on August 21, 2021, Evercore rendered its oral opinion to the Conflicts Committee that, as of August 21, 2021, based upon and subject to the assumptions, procedures, qualifications, limitations and other matters considered by Evercore in connection with the preparation of its opinion, the merger consideration to be received by the Partnership Unaffiliated Common Unitholders in the First Partnership Merger is fair, from a financial point of view, to the Partnership Unaffiliated Common Unitholders. Evercore subsequently confirmed its oral opinion in a written opinion (the “Written Opinion”) on the same date.

The opinion speaks only as of the date it was delivered and not as of the time the First Partnership Merger will be completed or any other date. The opinion does not reflect changes that may occur or may have occurred after August 21, 2021, that could alter the facts and circumstances on which Evercore’s opinion was based. It is understood that subsequent events may affect Evercore’s opinion, but Evercore does not have any obligation to update, revise or reaffirm its opinion.

Evercore’s opinion was directed to the Conflicts Committee (in its capacity as such), and only addressed the fairness from a financial point of view, as of the date of the opinion, to the Partnership Unaffiliated Common Unitholders of the merger consideration to be received by the Partnership Unaffiliated Common Unitholders in the First Partnership Merger. Evercore’s opinion did not address any other term or aspect of the Transaction Agreement or the First Partnership Merger. The full text of the Written Opinion, which describes the assumptions

For purposes of its analysis and opinion, Evercore assumed and relied upon, without undertaking any independent verification of, the accuracy and completeness of all of the information publicly available, and all of

available to it as of the date of its opinion and financial, economic, market, regulatory and other conditions and circumstances as they then existed and as could be evaluated by Evercore on the date of its opinion. It is understood that subsequent developments may affect the opinion and that Evercore does not have any obligation to update, revise or reaffirm the opinion.

Evercore did not conduct a physical inspection of the properties or facilities of the Partnership and was not asked to pass upon, and expressed no opinion with respect to, any matter other than whether, as of the date of its opinion, the consideration to be received by the Partnership Unaffiliated Common Unitholders in the First Partnership Merger is fair, from a financial point of view, to the Partnership Unaffiliated Common Unitholders. Evercore did not express any view on, and its opinion does not address, the fairness of the First Partnership Merger to, or any consideration received in connection therewith by, any other person, including the holders of any other class of securities, creditors or other constituencies of the Partnership, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Partnership or the Partnership GP, or any class of such persons, whether relative to the consideration or otherwise. Evercore was not asked to, nor did Evercore express any view on, and its opinion does not address, any other term or aspect of the Transaction Agreement or the First Partnership Merger, including, without limitation, the structure or form of the First Partnership Merger or the other transactions contemplated by the Transaction Agreement, or any term or aspect of any other agreement or instrument contemplated by the Transaction Agreement or entered into or amended in connection with the Transaction Agreement. Evercore’s opinion does not address the relative merits of the Transactions as compared to other business or financial strategies that might be available to the Partnership, nor does it address the underlying business decision of the Partnership to engage in the First Partnership Merger. In arriving at its opinion, Evercore was not authorized to solicit, and did not solicit, interest from any third party with respect to the acquisition of any or all of the Common Units or any business combination or other extraordinary transaction involving the Partnership. The

Analysis of the Partnership

Assumptions with Respect to the Partnership

Evercore performed its analyses utilizing the LMRK Financial Projections. A summary of the LMRK Financial Projections are available above in “—Unaudited Financial Projections of the Partnership” above. The LMRK Financial Projections were not adjusted by Evercore.

Analysis of the Partnership

Evercore performed a series of analyses to derive indicative valuation ranges for the Common Units and compared each of the resulting valuation ranges to the proposed merger consideration. Evercore performed its analyses utilizing the LMRK Financial Projections.

Discounted Cash Flow Analysis

Evercore performed a discounted cash flow analysis of the Partnership by valuing the cash flows to be received by the Partnership based on the LMRK Financial Projections. Evercore calculated the per unit value range for the Common Units by utilizing a range of discount rates with a mid-point equal to the Partnership’s weighted average cost of capital (“WACC”), as estimated by Evercore based on the Capital Asset Pricing Model (“CAPM”), and terminal values based on a range of estimated EBITDA exit multiples as well as perpetuity growth rates. Evercore assumed a range of discount rates of 6.5% to 7.5% based on the Partnership’s WACC range of 6.6% to 7.2%, a range of EBITDA exit multiples of 13.0x to 17.0x based on Evercore’s peer group trading analysis and a range of perpetuity growth rates of 2.0% to 3.0% based on the Partnership’s compound annual growth rate of projected Adjusted EBITDA from 2022A through 2026A of 2.5%, resulting in an implied equity value per unit range of $9.19 per unit to $25.25 per unit utilizing the LMRK Financial Projections.

Evercore noted that none of the selected transactions or the selected companies or partnerships that participated in, or assets involved in, the selected transactions were directly comparable to the Partnership:

Evercore reviewed the EBITDA multiples paid in the selected historical asset transactions and derived a range of relevant implied multiples of market value of equity, plus debt and preferred units, less cash (“Enterprise Value”) to EBITDA of 15.0x to 20.0x for its precedent transactions analysis. Evercore then applied

Peer Group Trading Analysis

Evercore performed a peer group trading analysis of the Partnership by reviewing and comparing the market values and trading multiples of the following 24 publicly traded partnerships and companies that Evercore deemed to have certain characteristics that are similar to those of the Partnership, divided into Master Limited Partnerships and Real Estate Investment Trust Companies:

Master Limited Partnerships:

The selected transactions and resulting minimum, maximum, mean and median data were as follows:

Utilizing the multiples illustrated above, Evercore determined an implied equity value per unit range of $8.59 per unit to $19.36 per unit using the LMRK Financial Projections.

Premiums Paid Analysis

Evercore also reviewed selected publicly available information for historical premiums paid in MLP acquisitions since January 2017 in (i) all transactions generally, and (ii) cash transactions specifically. Such analysis and presentation were prepared for reference only and are illustrative and presented for informational purposes only. Evercore considered that historically, merger and cash transaction premiums have varied widely based on specific considerations with respect to each transaction, with a range for cash transactions of (8.6%) to 63.7% premium to the one-day trailing price and a median premium for cash transactions of (i) 20.1% to the one-day trailing price, (ii) 9.8% to the 30-day trailing price and (iii) 13.4% to the 60-day trailing price, and a range for all transactions of (8.6%) to 65.4% premium to the one-day trailing price and a median premium for all transactions of (i) 13.5% to the one-day trailing price, (ii) 14.9% to the 30-day trailing price and (iii) 13.5% to the 60-day trailing price. Evercore noted that none of the selected transactions or the selected MLPs or companies that participated in the selected transactions was directly comparable to the First Partnership Merger and related transactions of the Partnership.

The selected transactions and resulting minimum, maximum, mean and median data were as follows:

Based on the relevant median premiums, Evercore calculated implied equity value per unit ranges of: (i) $13.53 to $14.13 for all transactions and (ii) $13.36 to $14.32 for cash transactions.

Other Presentations by Evercore

In addition to the presentation made to the Conflicts Committee on August 21, 2021, the date on which Evercore delivered its fairness opinion, as described above, Evercore made other written and oral presentations to the Conflicts Committee on July 22, 2021, July 30, 2021, and August 2, 2021, which are referred to as the preliminary Evercore presentations. Copies of the preliminary Evercore presentations have been attached as exhibits to the transaction statement on Schedule 13E-3 filed with the SEC with respect to the proposed First Partnership Merger. These written presentations will be available for any interested unitholder of the Partnership to inspect and copy at the Partnership’s executive offices during regular business hours.

None of these other written and oral presentations by Evercore, alone or together, constitutes an opinion of Evercore with respect to the merger consideration. The information contained in the written and oral presentations made to the Conflicts Committee on July 22, 2021, July 30, 2021, and August 2, 2021 is substantially similar to the information provided in Evercore’s written presentation to the Conflicts Committee on August 21, 2021, as described above.

Each of the analyses performed in these preliminary Evercore presentations was subject to further updating and subject to the final analyses presented to the Conflicts Committee on August 21, 2021 by Evercore. Each of

these analyses was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Evercore as of, the dates on which Evercore performed such analyses. Accordingly, the results of the financial analyses may have differed due to changes in those conditions and other information, and not all of the written and oral presentations contained all of the financial analyses included in the August 21, 2021 presentation.

Other Presentations by Evercore

In addition to the presentation made to the Conflicts Committee on August 21, 2021, the date on which Evercore delivered its fairness opinion, as described above, Evercore made other written and oral presentations to the Conflicts Committee on July 22, 2021, July 30, 2021, and August 2, 2021, which are referred to as the preliminary Evercore presentations. Copies of the preliminary Evercore presentations have been attached as exhibits to the transaction statement on Schedule 13E-3 filed with the SEC with respect to the proposed First Partnership Merger. These written presentations will be available for any interested unitholder of the Partnership to inspect and copy at the Partnership’s executive offices during regular business hours.

None of these other written and oral presentations by Evercore, alone or together, constitutes an opinion of Evercore with respect to the merger consideration. The information contained in the written and oral presentations made to the Conflicts Committee on July 22, 2021, July 30, 2021, and August 2, 2021 is substantially similar to the information provided in Evercore’s written presentation to the Conflicts Committee on August 21, 2021, as described above.

The Conflicts Committee selected Evercore to provide financial advice in connection with its evaluation of the First Partnership Merger because of, among other reasons, Evercore’s experience, reputation and its investment banking professionals’ experience in transactions similar to the First Partnership Merger.

During the two-year period prior to the date hereof, Evercore Group L.L.C. and its affiliates have not been engaged to provide financial advisory or other services to the Conflicts Committee, on behalf of the Partnership, and Evercore has not received compensation from Partnership GP, the Partnership, or Digital Colony Acquisitions, LLC during such period. Evercore may provide financial advisory or other services to the Partnership, Partnership GP and Digital Colony Acquisitions, LLC or its affiliates in the future, and in connection with any such services it may receive compensation, except that, until Evercore’s engagement by the Conflicts Committee terminates, Evercore may not provide such services to the Partnership GP, Landmark Dividend or certain affiliates of Digital Colony Acquisitions, LLC, in each case, without the prior written consent of the Conflicts Committee.

Position of the Buyer Parties as to the Fairness of the Transactions

Under the SEC rules governing “going private” transactions, each of the Buyer Parties is an Affiliate of the Partnership that is engaged in the “going private” transaction and, therefore, is required to express its position as to the fairness of the Transactions to the Partnership’s “unaffiliated security holders,” as defined under Rule 13e-3 of the Exchange Act. The Buyer Parties are making the statements included in this section solely for the purposes of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act. The views of the Buyer Parties as to the fairness of the Transactions (which is the Rule 13e-3 transaction for which a Schedule 13E-3 was filed with the SEC) should not be construed as a recommendation to any Partnership Unaffiliated Unitholder as to how such unitholder should vote on the proposal to approve the Transaction Agreement.

The Buyer Parties did not undertake an independent evaluation of the fairness of the Transactions to the Partnership Unaffiliated Unitholders or to the holders of Preferred Units or engage a financial advisor for such purpose. However, based on the procedural safeguards implemented during the negotiation of the Transaction Agreement, which included the delegation by the Board to the Conflicts Committee of the full power, authority and responsibilities of the Board to, on behalf of the Partnership, the Partnership Unaffiliated Unitholders and the Partnership GP in its capacity as general partner of the Partnership, to, among other things, (a) review, consider and evaluate the Transactions and the terms and conditions of the Transactions and any agreements and arrangements related thereto on behalf of the Partnership and the Partnership Unaffiliated Unitholders, (b) negotiate the terms and any documentation of the Transactions and related agreements directly with each of DigitalBridge and its affiliates and/or the Partnership’s management and the counsel and advisors to each of them, as it deemed necessary, appropriate or advisable, in its sole discretion, (c) consult with, advise and/or direct management of the Partnership in connection with discussions and/or negotiations concerning potential terms and conditions of the Transactions and related agreements, (d) determine whether the Transactions and related agreements were in the best interests of the Partnership, (e) determine whether to recommend that the Board approve or not approve, as applicable, the Transactions and related agreements, with any such approval and related recommendation of the Conflicts Committee constituting “Special Approval” for all purposes under the Partnership Agreement, including Section 7.9(b) thereof, with respect to the Transactions and related agreements and (f) make a recommendation to the Board whether it should (i) approve the Transactions and related agreements and (ii) recommend the Transactions to the Partnership Unaffiliated Unitholders, with the Board, acting for and on behalf of the Partnership GP in its capacity as the general partner of the Partnership, ultimately making a determination to approve or not approve the Transactions and agreements on behalf of the Partnership, and the other factors considered by the Buyer Parties in the section entitled “—The Buyer Parties’ Purpose and Reasons for the Transactions,” the Buyer Parties believe that the Transactions are substantively and procedurally fair to the Partnership Unaffiliated Unitholders. The Buyer Parties expressly adopted the analysis of the Conflicts Committee, which expressly adopted the analyses and opinion of Evercore, among other factors considered, in the course of reaching its decision that the Transactions are substantively and procedurally fair to the Partnership Unaffiliated Unitholders and the holders of Preferred Units. The Buyer Parties believe that the Transactions are substantively and procedurally fair to the holders of Preferred Units, as Preferred Units will be entitled to receive in the Transaction the exact consideration the holders of such Preferred Units would have received had they instead been redeemed rather than cashed out in the Transaction. For additional information, see “The Transaction Agreement—The Transactions Consideration.”

The Buyer Parties did not consider net book value, which is an accounting concept, for purposes of determining the fairness of the Transactions Consideration to the Partnership Unaffiliated Unitholders or of the Preferred Units Consideration because, in the Buyer Parties’ view, net book value is indicative of neither the Partnership’s market value nor its value as a going concern, but rather is an indicator of historical costs. The Buyer Parties did not consider the liquidation value of the Partnership for purposes of determining the fairness of the Transactions Consideration to the Partnership Unaffiliated Unitholders and of the Preferred Units Consideration to the holders of Preferred Units because it considered the Partnership to be a viable, going concern and therefore did not consider liquidation value to be a relevant methodology. The Buyer Parties did not conduct a going-concern valuation of the Partnership in evaluating the Transactions because of their belief that the financial analyses presented by Evercore to the Conflicts Committee, as more fully summarized below in the section entitled “Opinion of Evercore Group L.L.C.—Financial Advisor to the Conflicts Committee,” included potential valuations of the Partnership as it continues to operate its business as a going concern.

The foregoing discussion of the information and factors considered and given weight by the Buyer Parties is not intended to be exhaustive, but includes the factors considered by the Buyer Parties that each believes to be material to the fairness determination regarding the fairness of the Transactions for the purpose of complying with the requirements of Rule 13e-3 and the related rules under the Exchange Act. The Buyer Parties did not find it practicable to, and did not, quantify or otherwise attach relative weights to the foregoing factors in reaching their position as to the fairness of the Transactions. Rather, the Buyer Parties made their fairness determination after considering all of the factors as a whole.

The Buyer Parties’ Purpose and Reasons for the Transactions

Under the SEC rules governing “going private” transactions, each of the Buyer Parties is an Affiliate of the Partnership that is engaged in the “going private” transaction and, therefore, each is required to express its purposes and reasons for the Transactions to the Partnership’s “unaffiliated security holders,” as defined under Rule 13e-3 of the Exchange Act. The Buyer Parties are making the statements included in this section solely for the purpose of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act.

If the Transactions are completed, (a) all of the assets of the Partnership Parties will be owned by LM Infra, (b) the holders of Common Units and Preferred Units will no longer have an equity interest in the Partnership, (c) the Common Units and the Preferred Units will no longer be listed on the NASDAQ Global Market and cease to exist and (d) the registration of the Common Units and the Preferred Units under the Exchange Act will be terminated. For the Buyer Parties, the purpose of the Transactions is to effectuate the transactions contemplated by the Transaction Agreement and to bear the rewards and risks of such ownership after the Common Units and Preferred Units cease to be publicly traded and cease to exist. The Buyer Parties did not consider any alternatives for achieving these purposes.

The Buyer Parties believe that the Partnership could operate more efficiently and effectively as a private entity free from the pressures imposed on a publicly traded partnership. In particular, the Buyer Parties believe that telecom infrastructure assets are ill-suited to management through a master limited partnership structure, support for which can be seen by the disparities in stock prices between master limited partnerships managing telecom assets and REIT structures managing such assets. The Transaction Proposal, in the belief of the Buyer Parties, offers Unitholders and holders of Preferred Units greater certainty of value in exchange for the opportunity to eventually optimize the business under such an internally managed structure. Additionally, the Buyer Parties also believe the Transaction Proposal advantageously situates Unitholders and holders of Preferred Units to avoid increased general and administrative expenses as certain cost reimbursement mechanisms fall away over time. Further, the Buyer Parties considered what they believed were competitive advantages of the Partnership’s ceasing to exist and the assets ceasing to be owned by a public entity, including less transparency to competitors. Finally, absent the reporting and other substantial burdens placed on public entities, the Buyer Parties believe that the management and employees of Landmark Dividend will be able to better execute on its future strategic plans due to increased time and narrowed focus.

The Buyer Parties have undertaken to pursue the Transactions at this time for the reasons described above, as well as due to the Buyer Parties’ desire to maximize long-term investment returns for their partners.

Although the Buyer Parties believe that there will be certain opportunities associated with their ownership of the assets of the Partnership if the Transactions are completed, the Buyer Parties realize that there are also substantial risks (including the risks and uncertainties relating to the prospects of the Partnership) and that such opportunities may never be fully realized.

The Buyer Parties believe that a merger transaction is preferable to other transaction structures because the Transactions, including the First Partnership Merger and the Second Partnership Merger (a) will enable Buyer Parties to acquire all of the outstanding Common Units not owned by Landmark Dividend at the same time and all of the assets owned by the Partnership, (b) will enable the Buyer Parties to redeem all of the outstanding Preferred Units at the same time and (c) represents an opportunity for the Partnership Unaffiliated Unitholders to receive price certainty at a premium for their Common Units in the form of the Partnership Unaffiliated Unitholders Consideration based on the Partnership Unaffiliated Unitholders Consideration representing a premium of approximately (i) 38% to the $11.92 unaffected closing price on May 14, 2021, the last business day prior to the announcement of Landmark Dividend’s proposed acquisition of the Partnership for $13.00 per Common Unit and (ii) 16.5% to the $14.16 closing price per Common Unit on August 20, 2021, the last trading day before the announcement of the Transactions. Further, the Buyer Parties believe that the Transactions are substantively and procedurally fair to the holders of Preferred Units, as Preferred Units will be entitled to receive in the Transaction the exact consideration the holders of such Preferred Units would have received had they instead been redeemed rather than cashed out in the Transaction. For additional information, see “The Transaction Agreement—The Transactions Consideration.” Furthermore, the Buyer Parties believe that structuring the transaction as a merger transaction provides the most prompt payment to all of the Partnership Unaffiliated Unitholders in light of anticipated timing to obtain requisite regulatory approvals and the absence of a short form merger statute that would allow the Partnership to avoid the need to hold the Partnership Unitholder Meeting even if the Buyer Parties acquired a majority of the Common Units in a tender offer.

Effects of the Transactions

If the Transactions are completed, (a) at the effective time of the First Partnership Merger (the “First Partnership Merger Effective Time”), (i) each issued and outstanding Common Unit, other than the Landmark Dividend Common Units, will be converted into the right to receive $16.50 per Common Unit in cash without any interest thereon, (ii) each issued and outstanding Series A Preferred Unit will be converted into the right to receive $25.00 plus the amount of any accumulated and unpaid distributions per Series A Preferred Unit in cash without any interest thereon, (iii) each issued and outstanding Series B Preferred Unit will be converted into the right to receive $25.00 plus the amount of any accumulated and unpaid distributions per Series B Preferred Unit in cash without any interest thereon and (iv) each issued and outstanding Series C Preferred Unit will be converted into the right to receive the greater of (1) $25.00 plus the amount of any accumulated and unpaid distributions per Series C Preferred Unit to, but not including, the date of the First Partnership Merger Effective Time plus the amount of any distributions that would have accrued from the date of the First Partnership Merger Effective Time to, but not including, the 50th Business Day following the First Partnership Merger Effective Time and (2) the sum of (A) the product of (x) the Alternative Conversion Amount multiplied by (y) Partnership Unaffiliated Unitholders Consideration plus (B) the amount of any accumulated and unpaid distributions for all prior Series C Distribution Periods ending on or prior to the 20th Business Day following the First Partnership Merger Effective Time, per Series C Preferred Unit in cash without any interest thereon, (b) all of the Common Units converted into the right to receive the Partnership Unaffiliated Unitholders Consideration will no longer be outstanding and will automatically be cancelled and cease to exist, (c) all of the assets of the Partnership Parties will be owned by LM Infra, (d) the holders of Common Units and Preferred Units will no longer have an equity interest in the Partnership, (e) the Common Units and the Preferred Units will no longer be listed on the NASDAQ Global Market and cease to exist and (f) the registration of the Common Units and the Preferred Units under the Exchange Act will be terminated.

At the effective time of the Second Partnership Merger, each issued and outstanding Landmark Dividend Common Unit and all Incentive Distribution Rights (as defined in the Partnership Agreement) will be converted into the right for Landmark Dividend or its affiliates to receive a certain promissory note in an amount specified by LM DV Infra and the General Partner Interest (as defined in the Partnership Agreement) will be cancelled and retired and will cease to exist. No consideration will be delivered for such cancelled General Partner Interest.

At the Second Partnership Merger Effective Time the Partnership will merge with and into Merger Sub, the separate existence of the Partnership will cease and Merger Sub will survive and continue to exist as a Delaware limited liability company and all the property, rights, privileges and powers of the Partnership will vest in Merger Sub, and all debts, liabilities and duties of the Partnership will become the debts, liabilities and duties of Merger Sub

Interests of Certain Persons in the Transactions

General

In considering the recommendation of the Conflicts Committee with respect to the Transactions Proposal, the Unitholders and holders of Preferred Units should be aware that certain of the executive officers and directors of the Partnership GP have interests in the transaction that differ from, or are in addition to, the interests of the holders of Common Units and Preferred Units generally. These interests are summarized below.

The members of the Conflicts Committee were aware of these interests and the relationships described below and considered them in making their determinations and recommendations with respect to the Transaction Agreement and the Transactions. These interests and relationships, to the extent material, are further described below. For additional information, please read “—Background of the Transactions,” and “—Reasons for the Conflicts Committee’s Recommendation.”

Equity Interests of Directors and Executive Officers in the Partnership GP

Certain Partnership GP executive officers and directors own Common Units, as further described below in “Security Ownership of Certain Beneficial Owners, Management, Landmark Dividend and the Buyer Parties—

The following tables set forth certain information regarding the beneficial ownership of Common Units as of September 7, 2021 owned by:

Additionally, the Buyer Parties have agreed to, for a period of six years following the Closing Date (or until the disposition of claims for indemnification or advancement asserted during such six-year period):

Pursuant to their employment agreements with Landmark Dividend, each of the executive officers of Partnership GP are entitled to a cash transaction bonus payable within 30 days following the closing of the Transactions.

Certain Material United States Federal Income Tax Consequences

In general, the Second REIT Merger will be treated as a taxable event by the Partnership. The First Partnership Merger combined with the Second Partnership Merger will be part of a plan of liquidation of the Partnership where holders of Common Units will receive distributions of cash in liquidation of their Common Units. The Second REIT Merger and/or the distribution of cash to holders of Common Units in the First Partnership Merger may subject holders of Common Units to United States federal income tax depending on such holder’s own tax situation. Accordingly, you are strongly urged to consult your own tax advisor for a full understanding of the particular tax consequences of the Transactions to you.

Please read “Certain Material United States Federal Income Tax Consequences” for a more complete discussion of certain material United States federal income tax consequences to holders of Common Units of the Second REIT Merger and the receipt of cash by such holders in the First Partnership Merger.

The cases filed in the United States District Court for the Southern District of New York are captioned O’Dell v. Landmark Infrastructure LP et al., Case No. 1:21-cv-07635 (S.D.N.Y.) (the “O’Dell Action”), Whitfield v. Landmark Infrastructure Partners LP et al., Case No. 1:21-cv-07731 (S.D.N.Y.) (the “Whitfield Action”) and Robinson v. Landmark Infrastructure Partners LP, et al., Case No. 1:21-cv-07988 (S.D.N.Y.) (the “Robinson Action”). The case filed in the United States District Court for the District of New Jersey is captioned Delancy v. Landmark Infrastructure Partners LP et al., Case No. 2:21-cv-17971 (D. N.J.) (the “Delancy Action”). The case filed in the United States District Court for the Central District of California is captioned Unger v. Landmark Infrastructure Partners LP, et al., Case No. 2:21-cv-07849 (C.D. Cal.) (the “Unger Action” and, collectively with the O’Dell Action, the Whitfield Action, the Robinson Action and the Delancy Action, the “Actions”). The Actions are brought only on behalf of each named plaintiff.

Each of the Actions allege violations of Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder based on various alleged omissions of material information from the Partnership’s September 10, 2021 preliminary proxy statement (the “Proxy”) filed in connection with the Transactions. The O’Dell Action, the Whitfield Action, the Robinson Action, and the Delancy Action name as defendants the Partnership is not awareand each of any complaints filedthe Partnership GP’s directors, individually. The Unger Action names as a defendant the Partnership, four of the Partnership GP’s directors, individually (Arthur P. Brazy, Keith Benson, Thomas Carey White III, and Gerald A. Tywoniuk), and three of the Partnership GP’s former directors individually (Matthew P. Carbone, James F. Brown and Edmund G. Leung). All five Actions seek damages, expert and attorneys’ fees, and to enjoin the Unitholders vote required to consummate the proposed Transactions unless and until the defendants disclose the allegedly omitted material information. The Delancy Action, the O’Dell Action, and the Whitfield Action also seek a rescission of the proposed Transactions to the extent already consummated, or pending litigationan award of rescissory damages.

Each of the Partnership and the Partnership GP believes that the Actions are without merit and, along with the individual defendants, intends to defend against the Actions; however, neither the Partnership nor Partnership GP can predict the amount of time and expense that will be required to resolve the Actions or their outcomes. Additional lawsuits arising out of or related to the Transactions.proposed Transactions may also be filed in the future.

INFORMATION ABOUT THE PARTNERSHIP UNITHOLDER MEETING AND VOTING

Date, Time and Place

The Partnership Unitholder Meeting will be held on ,December 9, 2021 at ,10:00 AM, Pacific Time, located at .400 Continental Blvd., Suite 500, El Segundo, CA 90245. The meeting may be adjourned or postponed by the Partnership GP to another date or place for proper purposes, including for the purpose of soliciting additional proxies.

Purpose

The Unitholders will be asked to consider and vote upon the Transactions Proposal.

The Partnership will transact no other business at the Partnership Unitholder Meeting except such business as may properly be brought before Partnership Unitholder Meeting or any adjournments or postponements thereof. At this time, the Partnership knows of no other matters that will be presented for the consideration of the Unitholders at the Partnership Unitholder Meeting.

Record Date and Quorum Requirement

The Board has fixed the close of business on ,October 25, 2021 as the record date for the Partnership Unitholder Meeting. Unitholders that own Common Units at the close of business on the record date may vote at the Partnership Unitholder Meeting. You may cast one vote for Common Unit that you own as of the close of business on the record date. Votes may be cast at the Partnership Unitholder Meeting in person or by proxy.

The presence, in person or by proxy, at the Partnership Unitholder Meeting of holders of a majority of the Common Units, as of the record date, will constitute a quorum and will permit the Partnership to conduct the proposed business at the Partnership Unitholder Meeting. Common Units will be counted as present at the Partnership Unitholder Meeting if the Unitholder is present in person at the Partnership Unitholder Meeting or has submitted and not revoked a properly executed proxy card or properly submitted and not revoked a proxy via telephone or the Internet. Proxies received but marked as abstentions will be counted as Common Units that are present and entitled to vote for purposes of determining the presence of a quorum. A broker non-vote will also be considered present at the Partnership Unitholder Meeting for purposes of determining the presence of a quorum but cannot be included in the vote. Abstentions and broker non-votes have the same effect as a vote against the Transactions for purposes of the vote required under the Transactions Agreement and the Partnership Agreement.

Submitting a Proxy Card

Unitholders holding Common Units in their own name may submit their proxy by completing, signing, dating and mailing the enclosed proxy card in the enclosed postage-prepaid envelope. Submitting a proxy by this method will not affect your right to attend the Partnership Unitholder Meeting.

Unitholders holding Common Units in “street name” by a bank, broker or other nominee should follow the separate voting procedures, if any, provided by the bank, broker or other nominee with this proxy statement.

Submitting a Proxy via Telephone or Internet

Unitholders holding Common Units in their own name who choose to submit their proxy via telephone or the Internet should follow the instructions set forth on the enclosed proxy card. The telephone and Internet proxy procedures are designed to authenticate proxies by use of a personal control number, which appears on the proxy card. These procedures, which comply with Delaware law, allow you to appoint a proxy to vote your Common Units, and to confirm that your instructions have been properly recorded. If you submit your proxy via telephone or the Internet, you do not have to mail in your proxy card, but your proxy must be received by 11:59 p.m., Pacific Standard Time, on ,December 8, 2021, which may be extended in the sole discretion of the Partnership GP.

Unitholders holding Common Units in “street name” by a bank, broker or other nominee should follow the instructions provided with the proxy materials to determine if Internet or telephone proxy submission is available. If your bank, broker or other nominee does make Internet or telephone proxy submission available, please follow the instructions provided on the voting form supplied by your bank, broker or other nominee.

Revoking Your Proxy

If your Common Units are registered directly in your name with the transfer agent, you may revoke your proxy with regard to such shares at any time before it is voted at the Partnership Unitholder Meeting by:

If your Common Units are held through a bank, broker or other nominee, you should follow the instructions of your bank, broker or other nominee regarding the revocation of proxies. If your bank, broker or other nominee allows you to submit your proxy via telephone or Internet, you may be able to change your proxy by submitting a proxy again by telephone or Internet.

Questions and Additional Information

If you have any questions about the Transactions Proposal, need additional copies of this proxy statement or the enclosed proxy card or require assistance in voting Common Units, you should contact the Partnership’s proxy solicitor, ,Okapi Partners, at .212-297-0720.

Voting at the Partnership Unitholder Meeting

Submitting a proxy now will not limit your right to vote at the Partnership Unitholder Meeting if you decide to attend in person. If you plan to attend the Partnership Unitholder Meeting and wish to vote in person, you will be given a ballot at the Partnership Unitholder Meeting. Please note, however, that if your Common Units are held in “street name” by a bank, broker or other nominee, and you wish to vote at the Partnership Unitholder Meeting, you must bring to the Partnership Unitholder Meeting a proxy from the bank, broker or other nominee authorizing you to vote at the Partnership Unitholder Meeting. Please contact your bank, broker or other nominee for specific instructions.

Vote Required; How Common Units are Voted

Pursuant to the Transaction Agreement and the Partnership Agreement, holders of at least a majority of the issued and outstanding Common Units must affirmatively vote or consent in favor of the Transactions Proposal in order for it to be approved. Failures to vote, in addition to abstentions and broker non-votes, will have the same effect as a vote against the Transactions Proposal for purposes of the vote required under the Transaction Agreement and the Partnership Agreement.

If you have timely and properly submitted your proxy, clearly indicated your vote and have not revoked your proxy, your Common Units will be voted as indicated on your proxy. If you have timely and properly submitted your proxy but have not clearly indicated your vote, your Common Units will be voted “FOR” approval of the Transactions Proposal.

If any person or group other than the Partnership GP and its Affiliates acquires beneficial ownership of 20% or more of any class of units of the Partnership, that person or group loses voting rights on all of its shares. This

loss of voting rights does not apply to any person or group that acquires the shares from the Partnership GP or its Affiliates and any transferees of that person or group who are notified by the Partnership GP that they will not lose their voting rights, to any person or group who acquires the shares with the prior approval of the Board or to transferees of such person or group, provided such transferee is an Affiliate of the transferor.

If any other matters are properly presented for consideration at the Partnership Unitholder Meeting or any adjournment or postponement thereof, the persons named in the proxy will have the discretion to vote on these matters.

Common Units Beneficially Owned by the Partnership GP Directors and Executive Officers

The Partnership GP’s directors and executive officers beneficially own, collectively, 250,418 Common Units as of September 7, 2021. These Common Units represent, collectively, approximately 0.98% of the total voting power of The Partnership’s outstanding voting securities as of such date. The Partnership currently expects that all of its directors and executive officers will vote their Common Units in favor of the Transactions Proposal to be voted on at the Partnership Unitholder Meeting.

Proxy Solicitation

This proxy statement is being furnished in connection with the solicitation of proxies by the Partnership GP on behalf of the Conflicts Committee. The expenses of such solicitation, including the expenses of preparing, printing and mailing the proxy statement and materials used in the solicitation, will be borne by the party incurring such expenses. In addition to the mailing of this proxy statement, proxies also may be solicited by the Partnership GP’s and its Affiliates’ directors, officers and employees by telephone, electronic mail, letter, facsimile or in person, but no additional compensation will be paid to them. The Partnership may also reimburse brokers, custodians, nominees, fiduciaries and others for expenses incurred in forwarding proxy materials to the beneficial owners of Common Units.

THE TRANSACTIONS PROPOSAL

The Proposal

At the Partnership Unitholder Meeting, Unitholders are being asked to consider and approve the Transaction Agreement and the Transactions. A copy of the Transaction Agreement is attached as Annex A to this proxy statement.

Board Recommendation

The Board, after considering various factors, including the unanimous determination and recommendation of the Conflicts Committee, has determined that the Transaction Agreement and the transactions contemplated thereby, including the Transactions, are in the best interests of the Partnership and the Partnership Unaffiliated Unitholders and has approved the Transaction Agreement and the transactions contemplated thereby, including the Transactions.

Accordingly, the Board recommends that the Unitholders vote “FOR” the Transactions Proposal.

Vote Required

Pursuant to the Transaction Agreement and the Partnership Agreement, holders of at least a majority of the issued and outstanding Common Units must affirmatively vote or consent in favor of the Transactions Proposal in order for it to be approved. Failures to vote, in addition to abstentions and broker non-votes, will have the same effect as a vote against the Transactions Proposal for purposes of the vote required under the Transaction Agreement and the Partnership Agreement.

POSTPONEMENT OR ADJOURNMENT

Pursuant to the Partnership Agreement, prior to the date of the Partnership Unitholder Meeting, the Partnership GP, as the general partner of the Partnership, may postpone the Partnership Unitholder Meeting one or more times for any reason by giving no fewer than two days’ notice to each Unitholder entitled to vote at the meeting and a new record date does not need to be fixed if the postponement is not for more than 45 days. No vote of the Unitholders is required for any adjournment or postponement. If the requisite unitholder vote to approve the Transactions Proposal has not been received at the time of the Partnership Unitholder Meeting (or such adjourned meeting), the Partnership may choose to solicit additional proxies in favor of the Transactions Proposal.

OTHER MATTERS

Other Matters for Action at the Partnership Unitholder Meeting

As of the date of this proxy statement, the Board knows of no other matters that will be presented for consideration at the Partnership Unitholder Meeting other than as described in this proxy statement.

Householding of Partnership Unitholder Meeting

The SEC has adopted rules that permit companies and intermediaries (such as brokers or banks) to satisfy the delivery requirements for proxy statements with respect to two or more security holders sharing the same address by delivering a single notice or proxy statement addressed to those security holders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for security holders and cost savings for companies. Banks, brokers and other nominees may be participating in the practice of “householding” proxy statements and annual reports. As indicated in the notice provided by these banks, brokers and other nominees to Unitholders, a single proxy statement will be delivered to multiple Unitholders sharing an address unless contrary instructions have been received from an affected Unitholder. Once you have received notice from your bank, broker or other nominee that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you would prefer to receive separate copies of the proxy statement either now or in the future, please contact your bank, broker or other nominee or contact Okapi Partners, the Partnership’s proxy solicitor, or contact the Partnership by written or oral request to the Partnership at 400 Continental Blvd., Suite 500, El Segundo, CA 90245 or by telephone at (213) 788-4528.

THE TRANSACTION AGREEMENT

The following is a summary of the material terms of the Transaction Agreement. The provisions of the Transaction Agreement are extensive and not easily summarized. The following summary is qualified in its entirety by reference to the Transaction Agreement, a copy of which is attached to this proxy statement as Annex A and is incorporated into this proxy statement by reference. You should read carefully the Transaction Agreement in its entirety because it, and not this proxy statement, is the legal document that governs the terms of the Transactions.

The Transaction Agreement contains representations and warranties by each of the parties to the Transaction Agreement (each referred to individually as a “party” and collectively as the “parties”). The assertions embodied in those representations and warranties are qualified by information in confidential disclosure schedules that the parties have exchanged in connection with signing the Transaction Agreement. The disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the attached Transaction Agreement. Accordingly, you should keep in mind that the representations and warranties are modified in part by the underlying disclosure schedules. The disclosure schedules contain information that has been included in the Partnership’s prior public disclosures, as well as additional information, some of which may be non-public. Information concerning the subject matter of the representations and warranties may have also changed since the date of the Transaction Agreement, and all of this information may or may not be fully reflected in the Partnership’s public disclosures. Accordingly, the representations, warranties and covenants in the Transaction Agreement and the description of them in this proxy statement should not be read alone but instead should be read in conjunction with the other information contained in the reports, statements and filings of the Partnership filed with the SEC.

Regulatory Approvals Required for the Transactions

In connection with the Transactions, the Partnership intends to make all required filings under the Exchange Act, as well as any required filings with the NASDAQ Global Market and the Secretary of State of the State of Delaware.

Board Recommendation and Partnership Adverse Recommendation Change

By vote at a meeting of the Conflicts Committee on August 21, 2021, the Conflicts Committee unanimously (a) determined that the Transaction Agreement and the transactions contemplated thereby, including the Transactions, are in the best interests of the Partnership, including the Partnership Unaffiliated Unitholders, (b) approved the Transaction Agreement and the transactions contemplated thereby, including the Transactions, such approval constituting “Special Approval” of the Transaction Agreement and the transactions contemplated thereby, including the Transactions, for all purposes under the Partnership Agreement, and (c) recommended that the Board approve the Transaction Agreement, the execution, delivery and performance of the Transaction Agreement, and the consummation of the transactions contemplated thereby, including the Transactions. In evaluating the Transaction Agreement and the transactions contemplated thereby, the Conflicts Committee considered information supplied by DigitalBridge and Management, consulted with its legal and financial advisors, and considered a number of factors in reaching its determination, approval and recommendation. For a more complete discussion of these items, see “The Transactions—Reasons for the Conflicts Committee’s Recommendation.”

The Board (acting in part based upon the recommendation of the Conflicts Committee), at a meeting duly called and held, (a) determined that the Transaction Agreement and the consummation of the transactions contemplated thereby, including the Transactions, were in the best interests of the Partnership and the Partnership Unaffiliated Unitholders, (b) approved the Transaction Agreement, the execution, delivery and performance the Transaction Agreement and the consummation of the transactions contemplated thereby, including the Transactions, (c) resolved to submit the Transaction Agreement to a vote of the holders of Common Units and (d) resolved to recommend approval of the Transaction Agreement, including the Transactions, by the holders of Common Units.

The Transaction Agreement provides that the Partnership Parties will not, and will cause their respective subsidiaries and their respective representatives not to, directly or indirectly (a) withdraw, modify or qualify, or propose to publicly withdraw, modify or qualify, in a manner adverse to the Buyer Parties, the Board Recommendation or the Committee Recommendation or (b) fail to include the Board Recommendation in this proxy statement (any such action, a “Partnership Adverse Recommendation Change”).

Notwithstanding anything to the contrary in the Transaction Agreement, at any time prior to obtaining the Partnership Unitholder Approval, the Conflicts Committee may make a Partnership Adverse Recommendation Change in response to an Intervening Event if the Conflicts Committee determines in good faith, after consultation with its financial advisor and outside legal counsel, that the failure to effect such Partnership Adverse Recommendation Change would be inconsistent with its duties under applicable law, as modified by the Partnership Agreement. Any Partnership Adverse Recommendation Change shall have no effect on the validity of the Special Approval granted by the Conflicts Committee, which shall remain in full force and effect for all

purposes under the Partnership Agreement. The Conflicts Committee may not effect a Partnership Adverse Recommendation Change pursuant to the foregoing unless:

Unitholder Approval

Subject to the terms and conditions of the Transaction Agreement, the Partnership has agreed to, with the Buyer Parties’ cooperation, as promptly as practicable following the date of execution of the Transaction Agreement, establish a record date for, duly call, give notice of, convene and hold a special meeting of the Unitholders (including any postponements, adjournments or recesses thereof) for purposes of obtaining Unitholder Approval. See “Information About the Unitholder Meeting and Voting.”

Subject to the provisions of the Transaction Agreement relating to a Partnership Adverse Recommendation Change (as discussed above in “—Board Recommendation and Partnership Adverse Recommendation Change”), the Partnership has agreed to (unless the Conflicts Committee has made a Partnership Adverse Recommendation Change in accordance with the terms of the Transaction Agreement) through the Board, recommend to the Unitholders approval of the Transaction Agreement and the Transactions (collectively, the “Board Recommendation”) and use reasonable best efforts to obtain Partnership Unitholder Approval. The Partnership has further agreed to advise LM Infra promptly of any material communication received by the Partnership in writing after the date of execution of the Transaction Agreement related to any potential vote against the Transactions by any Unitholder having beneficial ownership of 5% or more of all of the issued and outstanding Common Units or any Unitholder that has notified the Partnership in writing that such Unitholder beneficially owns 2% or more of all of the issued and outstanding Common Units.

Unless the Transaction Agreement is validly terminated in accordance with its terms, the Partnership, with the Buyer Parties’ cooperation, must submit the Transaction Agreement to the Unitholders for approval at the Partnership Unitholder Meeting even if the Conflicts Committee has effected a Partnership Adverse Recommendation Change.

The Transaction Consideration

Under the terms of the Transaction Agreement, at the First Partnership Merger Effective Time, (a) each issued and outstanding Common Unit, other than the Landmark Dividend Common Units, will be converted into the right to receive $16.50 per Common Unit in cash without any interest thereon, (b) each issued and outstanding Series A Preferred Unit will be converted into the right to receive $25.00 plus the amount of any accumulated and unpaid distributions per Series A Preferred Unit in cash without any interest thereon, (c) each issued and outstanding Series B Preferred Unit will be converted into the right to receive $25.00 plus the amount

of any accumulated and unpaid distributions per Series B Preferred Unit in cash without any interest thereon and (d) each issued and outstanding Series C Preferred Unit will be converted into the right to receive the greater of (1) $25.00 plus the amount of any accumulated and unpaid distributions per Series C Preferred Unit to, but not including, the date of the First Partnership Merger Effective Time plus the amount of any distributions that would have accrued from the date of the First Partnership Merger Effective Time to, but not including, the 50th Business Day following the First Partnership Merger Effective Time and (2) the sum of (i) the product of (x) the Alternative Conversion Amount multiplied by (y) Partnership Unaffiliated Unitholders Consideration plus (ii) the amount of any accumulated and unpaid distributions for all prior Series C Distribution Periods ending on or prior to the 20th Business Day following the First Partnership Merger Effective Time, per Series C Preferred Unit in cash without any interest thereon.

At the effective time of the Second Partnership Merger, each issued and outstanding Landmark Dividend Common Unit and all Incentive Distribution Rights will be converted into the right for Landmark Dividend or its affiliates to receive the Equity Sales Note and the General Partner Interest will be cancelled and retired and will cease to exist. No consideration will be delivered for such cancelled General Partner Interest.

Treatment of Equity Awards

As promptly as practicable following the date of the Transaction Agreement, and in any event prior to the First Partnership Merger effective time, the Board (or, if appropriate, any committee of the Board administering the Partnership LTIP) will adopt resolutions, and the Partnership will take or cause to be taken all other actions as may be necessary or required in accordance with applicable law and the Partnership LTIP (including the award agreements in respect of awards granted thereunder) to give effect to the below treatment of Equity Participation Units and to terminate the Partnership LTIP effective as of the First Partnership Merger Effective Time.

Immediately prior to the First Partnership Merger Effective Time, each award of Equity Participation Units then outstanding and unsettled shall be settled, in accordance with the terms of the Partnership LTIP and the applicable award agreement, by a cash payment equal to the Partnership Unaffiliated Unitholders Consideration per Equity Participation Unit and, solely to the extent provided in the applicable award agreement and unpaid, an additional cash payment equal to the product of (a) the number of outstanding Equity Participation Units and (b) the value of any distribution equivalent rights.

All cash amounts payable to holders of Equity Participation Units to non-employee directors shall be payable to the paying agent to be paid to accounts designated by such holder of Equity Participation Units.

Distributions

Under the Transaction Agreement, the Partnership GP shall, subject to the requirements of the Partnership Agreement and the limitations of applicable law, cause the Partnership to declare and pay regular quarterly cash dividends of $0.20 per Common Unit to the holders of the Common Units with declaration, record and payment dates consistent with past practice. Under the Transaction Agreement, the Partnership is permitted to declare and pay distributions as required by the terms of the Series A Preferred Units, Series B Preferred Units and Series C Preferred Units.

To the extent applicable, holders of Common Units and Preferred Units, as applicable, immediately prior to the First Partnership Merger Effective Time will have continued rights to receive any distributions, without interest, with respect to such Common Units or Preferred Units, as applicable, with a record date occurring prior to the First Partnership Merger Effective Time that has been declared by the Partnership GP prior to the First Partnership Merger Effective Time or made by the Partnership with respect to such Common Units and Preferred Units, as applicable, in accordance with the terms of the Transaction Agreement and that remain unpaid as of the First Partnership Merger Effective Time.

Surrender of Common Units and Preferred Units

Prior to the Closing Date, LM Infra will appoint the Paying Agent for the purpose of exchanging Common Units, Series A Preferred Units, Series B Preferred Units and Series C Preferred Units, as applicable, for the

Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price, as applicable. As promptly as practicable after the effective time for the applicable merger, the surviving entity or its designee will send, or will cause the Paying Agent to send, to each applicable holder of record of Common Units, Series A Preferred Units, Series B Preferred Units or Series C Preferred Units, as applicable, other than The Depository Trust Company (“DTC”) as of the effective time of the applicable merger whose Common Units, Series A Preferred Units, Series B Preferred Units or Series C Preferred Units, as applicable, were converted into the right to receive the Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price a letter of transmittal including instructions explaining how to surrender Common Units or Preferred Units, as applicable, to the Paying Agent in exchange for the Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price, as applicable.

The Partnership will (i) deposit, or will cause to be deposited, with the Paying Agent an amount of cash equal to the amount of the aggregate Transactions consideration, including the Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference and the Series C Fundamental Change Redemption Price, as applicable payable pursuant to the Transaction Agreement and (ii) instruct the Paying Agent to deliver the Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price, as applicable pursuant to the terms of the Transaction Agreement. All such cash deposited with the Paying Agent is referred to as the “exchange fund.” The exchange fund will be used only for the purposes contemplated by the Transaction Agreement.

Holders of Common Units, Series A Preferred Units, Series B Preferred Units or Series C Preferred Units, as applicable, who deliver a properly completed and signed letter of transmittal and any other documents required by the Paying Agent will be entitled to receive a check in an amount equal to the aggregate amount of cash that such holder has a right to receive under the Transaction Agreement, provided that no person beneficially owning Common Units or Preferred Units through DTC will be required to deliver a letter of transmittal to receive the Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price, as applicable, that such holder is entitled to receive through DTC and will receive its Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price, as applicable, in accordance with the customary payment procedures of DTC and its participants following the effective time of the applicable merger.

From and after the effective time of the applicable Merger, there will be no further registration on the books of the Partnership of transfers of Common Units, Series A Preferred Units, Series B Preferred Units or Series C Preferred Units converted into the right to receive the Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price, as applicable. If Common Units or Preferred Units are presented to the Surviving Entity or the Paying Agent for transfer, they will be cancelled and exchanged for the Partnership Unaffiliated Unitholders Consideration, the Series A Liquidation Preference, the Series B Liquidation Preference or the Series C Fundamental Change Redemption Price, as applicable, provided for and in accordance with the procedures set forth in the Transaction Agreement.

Anti-Dilution Provisions

If between the date of execution of the Transaction Agreement and the First Partnership Merger Effective Time, the number of outstanding Common Units changes into a different number of units or a different class or series by reason of the occurrence or record date of any Unit dividend, subdivision, reclassification, recapitalization, split, split-up, Unit distribution, combination, exchange of Units or similar transaction, the Partnership Unaffiliated Unitholders Consideration and any other similar dependent item will be appropriately

adjusted to reflect fully the effect of such transaction and to provide the holders of Common Units, Series A Preferred Units, Series B Preferred Units or Series C Preferred Units, as applicable, the same economic effect as contemplated by the Transaction Agreement prior to such transaction.

Withholding

Each of the Buyer Parties, the surviving entity and the Paying Agent will be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Transaction Agreement such amounts, if any, as are required to be deducted and withheld with respect to the making of such payment under the Code (as defined in “Certain Material United States Federal Income Tax Consequences”) and the United States Treasury Regulations, or under any provision of state, local or foreign tax law. To the extent that amounts are withheld and timely paid over to the appropriate taxing authority, such amounts will be treated for all purposes of the Transaction Agreement as having been paid to the person or entity in respect of whom such withholding was made.

The parties have agreed to, and to cause their respective Affiliates to (a) make or cause to be made any filings to the extent required or requested of such party or any of its subsidiaries under any applicable laws or by any governmental authority with competent jurisdiction with respect to the Transaction Agreement and the Transactions as promptly as is reasonably practicable (including making the required filings under the required approvals within ten (10) Business Days after the date of the Transaction Agreement), (b) reasonably cooperate with the other parties and furnish all information in such party’s possession that is necessary in connection with any other party’s filings, (c) use commercially reasonable efforts to secure the expiration or termination of any applicable waiting period and clearance or approval by any relevant governmental authority with respect to the Transaction Agreement and Transactions as promptly as is reasonably practicable, (d) promptly inform the other parties of (and, at any other party’s reasonable request, supply to such other party) any communication, correspondence, submission or memoranda from or to, and any proposed understanding or agreement with, any governmental authority in respect of any applicable filings, (e) comply, as promptly as is reasonably practicable and with due regard to maintaining the confidentiality of information that would be commercially harmful if publicly disclosed, with any requests received by such party or any of its Affiliates under any laws for additional information, documents, submissions or other materials, (f) use commercially reasonable efforts to respond to and resolve any questions that may be raised, or objections as may be asserted, by any governmental authority with respect to Transaction Agreement, the other transaction documents and the Transactions and (g) use commercially reasonable efforts to contest and resist any proceeding instituted (or threatened in writing to be instituted) by any governmental authority challenging the Transaction Agreement or the Transactions as violative of any law. All cooperation will be conducted in such a manner so as to preserve all applicable privileges.

Termination

The Transaction Agreement may be terminated and the Transactions may be abandoned at any time prior to the Closing Date:

Termination Fees

If the Transaction Agreement is terminated by LM Infra in connection with a Partnership Adverse Recommendation Change or is terminated by the Partnership or LM Infra if the Closing has not been consummated on or before the Outside Date at a time when LM Infra could have terminated the Transaction Agreement in connection with a Partnership Adverse Recommendation Change, the Partnership will promptly, but in no event later than ten business days after the date of such termination, pay to LM Infra or its designee a termination fee in an amount equal to $7.30 million. If the Transaction Agreement is terminated by the Partnership following a Closing Failure Notice or is terminated by the Partnership or LM Infra if the Closing has not been consummated on or before the Outside Date at a time when the Partnership could have terminated the Transaction Agreement following a Closing Failure Notice, Landmark Dividend or its designee will promptly, but in no event later than ten business days after the date of such termination, pay or cause to be paid to the Partnership a termination fee in an amount equal to $18.25 million.

Effect of Termination; Remedies

In the event of termination of the Transaction Agreement in accordance with the provisions described in “—Termination,” the Transaction Agreement (other than the provisions described in “—Termination Fees” and certain other specific sections of the Transaction Agreement) will become null and void and of no further force and effect, and each of the parties shall be relieved of their duties and obligations arising under the Transaction Agreement after the date of such termination and the parties will have no further liability under the Transaction Agreement, except that the parties will continue to be liable under certain indemnification, distribution, termination and specific performance provisions for fraud or willful breach of the Transaction Agreement.

Without limiting the rights of the parties pursuant to the provisions of the Transaction Agreement described in “—Specific Performance; Remedies” below, the enforcement of the Transaction Agreement in accordance with the provisions of the Transaction Agreement described in “—Specific Performance; Remedies” and termination of the Transaction Agreement in accordance with its terms and any receipt of any termination fees in connection therewith pursuant to the provisions of the Transaction Agreement described in this section are the sole and exclusive remedies of the parties for any losses or liabilities suffered or incurred by any party with respect to the Transaction Agreement and the Transactions as a result of the failure of the Closing to occur or the Transactions to be consummated for any or no reason or, in the event of a failure of the Closing to occur or the Transactions to be consummated for any reason or for no reason, for any breach of the Transaction Agreement by any party. Under no circumstance will any person or entity be permitted or entitled both to obtain specific performance and to receive any portion of any termination fee.

Conduct of Business Pending the Transactions

From the date of execution of the Transaction Agreement until the Closing Date, (a) the Partnership GP will cause the Partnership and its subsidiaries to, operate in the ordinary course of business consistent with past practices in all material respects except as prohibited by applicable law or as otherwise contemplated by the Transaction Agreement or any other transaction documents, provided, that the Partnership Entities shall not be prohibited from taking commercially reasonable actions outside of the ordinary course of business or not consistent with past practice in response to (i) changes or developments resulting from the COVID-19 pandemic or (ii) other changes or developments that would reasonably be expected to cause a reasonably prudent company similar to the Partnership Entities to take commercially reasonable actions outside of the ordinary course of

business consistent with past practice and in a manner not involving the entry by any Partnership Entity into businesses that are materially different from the businesses of the Partnership Entities on the date of the Transaction Agreement and (b) the Partnership GP shall, subject to the requirements of the Partnership Agreement and the limitations of applicable Law, cause the Partnership to declare and pay regular quarterly cash dividends of $0.20 per Common Unit to the holders of the Common Units with declaration, record and payment dates consistent with past practice.

Except (a) as provided in the Transaction Agreement or any other transaction documents, (b) as set forth on the disclosure schedules delivered by the Partnership, (c) as required by applicable law or COVID-19 measures or (d) as consented to in writing by LM Infra (which consent may not be unreasonably withheld, delayed or conditioned), prior to the Closing Date, the Partnership GP will not, and will cause the other Partnership Entities not to, as applicable:

Indemnification and Insurance

From and after the Closing, the Buyer Parties and the surviving entity have agreed to indemnify and hold harmless each Covered Person from and against any and all losses, claims, damages, liabilities, expenses, judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending, or completed claims, demands, actions, suits or proceedings, relating to or arising out of the Transaction Agreement, the other transaction documents or the Transactions, in which any such Covered Person may be involved by reason of its status as a Covered Person and acting (or omitting or refraining to act) in such capacity on behalf of or for the benefit of the Partnership. The Buyer Parties and the surviving entity have also agreed to advance to any such Covered Person expenses (including legal fees and expenses) incurred by such Covered Person in connection therewith. The rights to indemnification and advancement of expenses described in this paragraph are limited to the extent provided in, and in accordance with, the organizational documents of the Partnership Entities as of the date of execution of the Transaction Agreement.

Additionally, the Buyer Parties have agreed to, for a period of six years following the Closing Date (or until the disposition of claims for indemnification or advancement asserted during such six-year period):

In the event that any Buyer Party or any Partnership Entity consolidates with or merges into any other entity and is not the continuing or surviving entity of such consolidation or merger or transfers all or substantially all of

its properties and assets to any person or entity (whether by consolidation, merger or otherwise), then, and in each such case, proper provision will be made so that such continuing or surviving entity or transferee of such assets, as the case may be, assumes the obligations described in this section.

Conflicts Committee

Prior to the First REIT Merger Effective Time and the termination of the Transaction Agreement in accordance with its terms, neither the Partnership GP nor any Buyer Party will, without the consent of the Conflicts Committee, eliminate the Conflicts Committee, or revoke or diminish the authority of the Conflicts Committee, or remove or cause the removal of any member of the Board that is a member of the Conflicts Committee either as a member of such board or such committee, without the affirmative vote of the members of the Board, including the affirmative vote of each of the other members of the Conflicts Committee. For the avoidance of doubt, these restrictions will not apply to the filling of any vacancies caused by the death, incapacity or resignation of any such director in accordance with the provisions of the limited liability agreement of the Partnership GP.

Voting

Pursuant to the terms of the Transaction Agreement, each of Landmark Dividend and the Buyer Parties agreed (i) to vote all Common Units then owned beneficially or of record by it or any of its subsidiaries in favor of the approval of the Transaction Agreement and the Transactions and (ii) not to, and to cause each of their subsidiaries not to, directly or indirectly, transfer, assign or otherwise dispose of any Common Units owned by Landmark Dividend, such Buyer Party or its subsidiaries, other than to any of their respective Affiliates so long as such Affiliates agree to be bound by such obligations to the same extent as the Buyer Parties and Landmark Dividend.

Amendments and Supplements

Prior to the Closing, any provision of the Transaction Agreement may be amended or supplemented in any and all respects at any time, whether before or after the Partnership Unitholder Approval is obtained, by an agreement in writing between the parties, which must be authorized on behalf of the Buyer Parties by LM Infra and on behalf of the Partnership Parties by the Conflicts Committee. Notwithstanding the foregoing, following receipt of the Partnership Unitholder Approval, no amendment to the Transaction Agreement may be made that requires the approval of the Unitholders without obtaining such approval.

Waiver

Prior to the First REIT Merger Effective Time, any party may, subject to applicable law, (a) waive any inaccuracies in the representations and warranties of any other party, (b) extend the time for performance of any of the obligations or acts of any other party, (c) waive compliance by any other party with any agreements contained in the Transaction Agreement or, except as otherwise provided in the Transaction Agreement, conditions of such party, or (d) make or grant any consent under the Transaction Agreement, which must be authorized on behalf of the Partnership Parties by the Conflicts Committee.

Action by the Partnership

Any determination, decision, action, approval, consent, waiver or agreement of the Partnership Parties that is required or may be given pursuant to the Transaction Agreement (including any determination to exercise any termination rights under the Transaction Agreement or enforce specifically the terms of the Transaction Agreement) or any other transaction document must be authorized by the Conflicts Committee and, unless otherwise required by the Partnership Agreement or applicable law, such action shall not require approval of the

Common Units. Actions or inactions by the Partnership, the Partnership GP or any other Partnership Entity shall not be deemed to be breaches or violations or failures to perform by the Partnership Parties of any of the provisions of the Transaction Agreement if such action or inaction was or was not taken, as applicable, at the written direction or with the written consent of the Buyer Parties or Landmark Dividend or any of their respective Affiliates or representatives.

Specific Performance; Remedies

The Transaction Agreement provides that the parties are entitled to an injunction or injunctions to prevent breaches of the Transaction Agreement and to enforce specifically the terms and provisions of the Transaction Agreement.

Governing Law

The Transaction Agreement is governed by and interpreted under Delaware law.

Representations and Warranties

The Transaction Agreement contains representations and warranties of the parties to the Transaction Agreement. These representations and warranties, as applicable, concern, among other things:

Many of the representations and warranties in the Transaction Agreement provide that such representation and warranty does not extend to matters where the failure of the representation and warranty to be accurate would not result in a material adverse effect on the party making the representation and warranty. For purposes of the Transaction Agreement, “material adverse effect,” when used with respect to a Buyer Party means any event, change, fact, development, circumstance, condition or occurrence that would materially impair or impede the ability of the Buyer Parties or their Affiliates to perform their respective obligations or to consummate the transactions under the Transaction Agreement or any other transaction documents, including the Transactions, or the Commitment Letters. For purposes of the Transaction Agreement, “material adverse effect,” when used with respect to a Partnership Entities means any event, change, fact, development, circumstance, condition or occurrence that is materially adverse to, or has had or would reasonably be expected to have a material adverse effect on or change in, on or to the business, condition (financial or otherwise) or operations of the Partnership Entities, taken as a whole.

The following (either alone or in combination) will not be taken into account for purposes of determining whether or not a material adverse effect has occurred when such term is used with respect to a Partnership Entity:

Additional Agreements

The Transaction Agreement also contains covenants relating to cooperation in the preparation of this proxy statement and the Schedule 13E-3 transaction statement and additional agreements relating to, among other things, access to information, confidentiality, applicability of takeover statutes, public announcements, litigation and the cooperation of the parties with respect to the debt financing to be obtained by the Buyer Parties in connection with the Transactions.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a discussion of United States federal income tax consequences to U.S. Holders and Non-U.S. Holders (each as defined below) of the Second REIT Merger and the receipt of cash by such U.S. Holders and Non-U.S. Holders in the First Partnership Merger. This discussion is limited to holders of Common Units that hold their Common Units as capital assets for United States federal income tax purposes (generally, property held for investment). This discussion does not address tax consequences that may be relevant to particular holders in light of their individual circumstances, including, without limitation:

If a partnership, or any entity or arrangement treated as a partnership for United States federal income tax purposes, holds Common Units, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. A partner in a partnership holding Common Units should consult its own tax advisor.

Moreover, this discussion does not address any tax consequences arising under the net investment income tax, United States federal estate and gift tax or the alternative minimum tax, nor does it address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any United States federal laws other than those pertaining to income taxes.

This discussion is based upon provisions of the Code, and United States Treasury regulations, administrative rulings and judicial decisions thereunder as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those summarized below. We have not sought and will not seek any rulings from the Internal Revenue Service (“IRS”) regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences to holders of Common Units that are different from those discussed below.

As used herein, a “U.S. Holder” is a beneficial owner of Common Units that is, for United States federal income tax purposes, any of the following:

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of Common Units that is, for United States federal income tax purposes, an individual, corporation, estate or trust and is not a United States Holder.

THIS DISCUSSION IS PROVIDED FOR GENERAL INFORMATION ONLY AND IS NOT A COMPLETE ANALYSIS OR DESCRIPTION OF ALL POTENTIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTIONS. EACH HOLDER OF COMMON UNITS IS STRONGLY URGED TO CONSULT WITH AND RELY UPON ITS OWN TAX ADVISOR AS TO THE SPECIFIC FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES TO SUCH HOLDER OF THE TRANSACTIONS, TAKING INTO ACCOUNT ITS OWN PARTICULAR CIRCUMSTANCES.

Tax Consequences of the Second REIT Merger

Tax Characterization of the Second REIT Merger

The Second REIT Merger will be a taxable transaction to the Partnership for United States federal income tax purposes, and the Partnership will recognize all of its gain or loss. Gain or loss recognized by the Partnership on the Second REIT Merger will generally be taxable as capital gain or loss. Capital gain or loss recognized by the Partnership will generally be long-term capital gain or loss if the Partnership has held its interest in the REIT Subsidiary for more than twelve months as of the Second REIT Merger Effective Time.

Allocation of Gain or Loss to U.S. Holders in the Second REIT Merger

As a partnership, the Partnership generally will not be subject to United States federal income tax. Instead, each U.S. Holder will be allocated its share of the Partnership’s items of income, gain, loss, and deduction realized in the Second REIT Merger in accordance with the terms of the Partnership Agreement.

The Partnership has made the election permitted by Section 754 of the Code. The election generally permits the Partnership to adjust a Common Unit purchaser’s tax basis in the Partnership’s assets (“inside basis”) under Section 743(b) of the Code to reflect their purchase price (the “Section 743(b) Adjustment”). This election does not apply with respect to a person who purchases Common Units directly from the Partnership. The Section 743(b) Adjustment belongs to the purchaser of Common Units and not to other Unitholders. If a U.S. Holder has a Section 743(b) Adjustment, their allocable share of any gain or loss in the Second REIT Merger may be greater or lower than if they did not have such Section 743(b) Adjustment. The calculations involved in the Section 754 election, and resulting Section 743(b) Adjustment, are complex and will be made on the basis of assumptions as to the value of the Partnership’s assets and other matters.

Any such income and gain allocated to a U.S. Holder will increase the U.S. Holder’s tax basis in the Common Units held and, therefore, will reduce the gain, or increase the loss, recognized by such U.S. Holder resulting from the distribution of cash in the First Partnership Merger. Any losses or deductions allocated to a U.S. Holder will decrease the U.S. Holder’s tax basis in the Common Units held and, therefore, will increase the gain, or reduce the loss, recognized by such U.S. Holder resulting from the distribution of property in the First Partnership Merger. Each U.S. Holder will be required to include in income his allocable share of the Partnership’s income, gains, losses and deductions for the Partnership’s taxable year ending with or within his taxable year. The Partnership’s taxable year ends on December 31. Each item of income, gain, loss and deductions will have the same character in the hands of a U.S. Holder as in the hands of the Partnership, as though the U.S. Holder realized the item directly.

Allocation of Gain or Loss to Non-U.S. Holders in the Second REIT Merger

As a partnership, the Partnership generally will not be subject to United States federal income tax. Subject to the discussion below regarding FIRPTA (as defined below), a Non-U.S. Holders will not be taxable for United States federal income tax on their allocable share of the Partnership’s items of income, gain, loss, and deduction realized by the Partnership in the Second REIT Merger unless (i) such Non-U.S. Holder is a non-resident alien individual who is present in the United States for 183 days or more during the taxable year and some other conditions apply or (ii) such income or gain is effectively connected with such Non-U.S. Holder’s conduct of a trade or business in the United States.

A Non-U.S. Holder will be subject to United States federal income tax on the Non-U.S. Holder’s allocable share of the Partnership’s gain recognized on the Equity Sales to the extent any portion of the Equity Sales are treated as dispositions by the REIT LLC and/or REIT Subsidiary of “United States real property interests,” (“USRPIs”), under the Foreign Investment in Real Property Tax Act of 1980, as amended (“FIRPTA”). A USRPI includes certain interests in real property and shares in corporations at least 50% of whose assets consist of interests in real property. All or a portion of the Equity Sales will be treated as dispositions of USRPIs by the REIT LLC and REIT Subsidiary, and all or a portion of the gain allocable to a Non-U.S. Holder will be with respect to “capital gain distributions” from the REIT LLC and REIT Subsidiary and will be subject to tax under FIRPTA. Non-U.S. Holders generally will be subject to United States federal income tax upon the allocation of gain with respect to “capital gain distributions” as if such amounts were effectively connected to the United States trade or business of such Non-U.S. Holder. A Non-U.S. Holder thus would be taxed on such allocation at the normal United States federal capital gains rates applicable to U.S. Holders and will be required to file a United States federal income tax return reporting such amounts. A Non-U.S. Holder that is a corporation also may be subject to a 30% branch profits tax with respect to such allocation, unless reduced by an applicable tax treaty. The Partnership or the applicable withholding agent must withhold 21% of any distributions to a Non-U.S. Holder to the extent such Non-U.S. Holder has been allocated income with respect to “capital gain distributions.” Each Non-U.S. Holder may receive a credit against its tax liability for the amount the Partnership withholds.

Tax Consequences of the First Partnership Merger

U.S. Holders

A U.S. Holder who receives a cash distribution pursuant to the First Partnership Merger, which combined with the Second Partnership Merger will be part of a plan of liquidation of the Partnership, will recognize gain or loss in an amount equal to the difference between (i) the sum of (A) the amount of cash received by such U.S. Holder and (B) such U.S. Holder’s share of the Partnership’s nonrecourse liabilities immediately prior to the First Partnership Merger and (ii) such U.S. Holder’s adjusted tax basis in the Common Units (which includes such U.S. Holder’s share of the Partnership’s nonrecourse liabilities immediately prior to the First Partnership Merger).

A U.S. Holder’s initial tax basis in Common Units purchased with cash equaled, at the time of such purchase, the amount such U.S. Holder paid for the Common Units plus the U.S. Holder’s share of the

Partnership’s nonrecourse liabilities. Over time that basis has (i) increased by the U.S. Holder’s share of the Partnership’s income and gain (including gain from the Second REIT Merger) and by any increases in the U.S. Holder’s share of the Partnership’s nonrecourse liabilities, and (ii) decreased, but not below zero, by distributions from the Partnership, by the U.S. Holder’s share of the Partnership’s losses (including losses from the Second REIT Merger), by any decreases in the U.S. Holder’s share of the Partnership’s nonrecourse liabilities and by the U.S. Holder’s share of the Partnership’s expenditures that are not deductible in computing taxable income and are not required to be capitalized. Upon the liquidation of a Common Unit in the First Partnership Merger combined with the Second Partnership Merger, a U.S. Holder’s basis in their Common Units will be increased by the U.S. Holder’s share of certain items related to business interest not yet deductible by such U.S. Holder due to applicable limitations on the deductibility of such business interest.

Except as noted below, gain or loss recognized by a U.S. Holder on the distribution of cash in liquidation of Common Units in the First Partnership Merger combined with the Second Partnership Merger will generally be taxable as capital gain or loss. However, a portion of this gain or loss will be separately computed and taxed as ordinary income or loss under Section 751 of the Code to the extent attributable to “unrealized receivables,” including depreciation recapture, or to “inventory items” owned by the Partnership and its subsidiaries. Ordinary income attributable to unrealized receivables and inventory items may exceed net taxable gain realized upon the receipt of cash in the First Partnership Merger and may be recognized even if there is a net taxable loss realized on the receipt of such cash. The Partnership, however, does not expect a significant amount of gain or loss to be subject to this recharacterization.

Capital gain or loss recognized by a U.S. Holder will generally be long-term capital gain or loss if the U.S. Holder has held its Common Units for more than twelve months as of the First Partnership Merger Effective Time. If the U.S. Holder is an individual, such long-term capital gain will generally be eligible for reduced rates of taxation. Capital losses recognized by a U.S. Holder may offset capital gains and, in the case of individuals, no more than $3,000 of ordinary income. Capital losses recognized by U.S. Holders that are corporations may only be used to offset capital gains.

The amount of gain or loss recognized by each U.S. Holder in on the receipt of cash in the First Partnership Merger will vary depending on each U.S. Holder’s particular situation, including the adjusted tax basis of the Common Units held by each U.S. Holder, and the amount of any suspended passive losses that may be available to a particular U.S. Holder to offset a portion of the gain recognized. Passive losses that were not deductible by a U.S. Holder in prior taxable periods because they exceeded a U.S. Holder’s share of the Partnership’s income may be deducted in full upon the U.S. Holder’s taxable liquidation of its Common Units pursuant to the First Partnership Merger combined with the Second Partnership Merger. Each U.S. Holder is strongly urged to consult its own tax advisor with respect to such U.S. Holder’s specific tax consequences of the Transactions, taking into account its own particular circumstances.

Non-U.S. Holders.

A Non-U.S. Holder who receives a cash distribution pursuant to the First Partnership Merger, which combined with the Second Partnership Merger will be part of a plan of liquidation of the Partnership, will not be subject to United States federal income tax unless (i) such Non-U.S. Holder is a non-resident alien individual who is present in the United States for 183 days or more during the taxable year and some other conditions apply or (ii) such distribution is effectively connected with such Non-U.S. Holder’s conduct of a trade or business in the United States. As discussed above under “Tax Consequences of the Second REIT Merger—Allocation of Gain or Loss to Non-U.S. Holders in the Second REIT Merger,” the Partnership must withhold 21% of any distributions to a Non-U.S. Holder to the extent such Non-U.S. Holder has been allocated income with respect to “capital gain distributions.”

Information Reporting and Backup Withholding

The Partnership may be required to file information returns with the IRS in connection with cash distributions pursuant to the First Partnership Merger. A U.S. Holder may be subject to United States backup withholding (currently at a rate of 24%) on such distributions unless such U.S. Holder provides the applicable withholding agent with proof of its exemption from backup withholding or furnishes the applicable withholding agent with its taxpayer identification number, certified under penalties of perjury, and otherwise complies with all applicable requirements of the backup withholding rules. Backup withholding will generally not apply to distributions to a Non-U.S. Holder provided that the Non-U.S. Holder provides the applicable withholding agent the required certification as to its non-U.S. status, such as providing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or certain other requirements are met.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against United States federal income tax liability, if any, provided that certain required information is timely furnished to the IRSIRS.

About The Partnership

The Partnership is a partnership formed by Landmark Dividend to acquire, develop, own and manage a portfolio of real property interests and infrastructure assets that are leased to companies in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries. The Partnership is a master limited partnership organized in the State of Delaware and has been publicly traded since its initial public offering on November 19, 2014. The Partnership holds substantially all of its assets in a consolidated subsidiary, REIT Subsidiary, which elected to be taxed as a real estate investment trust under Code commencing with its taxable year ending December 31, 2017.

The Partnership’s real property interests underlie its tenants’ infrastructure assets, which include freestanding cellular towers and rooftop wireless sites, powered shell spaces for data centers, billboards, wind turbines, solar arrays and development equipment. These assets are essential to the operations and profitability of our tenants. The Partnership seeks to acquire real property interests subject to triple net or effectively triple net lease arrangements containing contractual rent increase clauses, or “rent escalators,” which it believes provide us with stable, predictable and growing cash flow. In certain instances, the Partnership owns the infrastructure and lease the infrastructure to our tenants.

The Partnership’s real property interests generally consist of a diversified portfolio of long-term and perpetual easements, tenant lease assignments, fee simple properties and infrastructure assets located primarily in the United States and Canada. These real property interests and other infrastructure entitle the Partnership to receive rental payments from leases on our 1,986 tenant sites as of December 31, 2020.

The Partnership GP is a Delaware limited liability company and is the general partner of the Partnership. The Partnership GP is responsible for conducting the Partnership’s business and managing its operations.

During the last five years, none of the Partnership Entities has been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and, as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

The Common Units are listed on the NASDAQ Global Market under the symbol “LMRK.” The principal executive offices of the Partnership and the Partnership GP are located at 400 Continental Blvd., Suite 500, El Segundo, CA 90245, and its telephone number is (310) 598-3173.

The Partnership GP’s board of directors and executive officers manage The Partnership’s operations and activities.

During the past five years, none of the directors or executive officers of the Partnership GP has been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) party to any judicial or administrative proceeding (except for matters that were dismissed without sanction or settlement) that resulted in a judgment, decree or final order enjoining the person from future violations of, or prohibiting activities subject to, federal or state securities laws or a finding of any violation of federal or state securities laws.
