NOTES TO CONDENSED FINANCIAL STATEMENTS (UNAUDITED)

(1) Trust Organization

        Tenneco Offshore Company, Inc. ("Tenneco Offshore") created the TEL Offshore Trust ("Trust") effective January 1, 1983, pursuant to the Plan of Dissolution ("Plan") approved by Tenneco Offshore's stockholders on December 22, 1982. In accordance with the Plan, the TEL Offshore Trust Partnership ("Partnership") was formed in which the Trust owns a 99.99% interest and Tenneco Oil Company had initially owned a .01% interest. In general, the Plan was effected by transferring an overriding royalty interest equivalent to a 25% net profits interest (the "Original Royalty") in the oil and gas properties (the "Royalty Properties") of Tenneco Exploration, Ltd. located offshore Louisiana to the Partnership and issuing certificates evidencing units of beneficial interest in the Trust ("Units") in liquidation and cancellation of Tenneco Offshore's common stock. The term "Original Royalty" shall refer to the initial 25% net profits interest in the Royalty Properties and the term "Royalty" shall refer to the applicable net profits interest previously held from time to time by the Partnership following the Royalty Sales (as defined in Note 3 below).

        On January 14, 1983, Tenneco Offshore distributed Units to holders of Tenneco Offshore's common stock on the basis of one Unit for each common share owned on such date.

        The terms of the Trust Agreement, dated January 1, 1983 (as amended, the "Trust Agreement"), provide, among other things, that:

        (a)   the Trust is a passive entity and cannot engage in any business or investment activity or purchase any assets;

        (b)   the interest in the Partnership can be sold in part or in total for cash upon approval of a majority of the Unit holders;

        (c)   the Trustees, as defined below, can establish cash reserves and borrow funds to pay liabilities of the Trust and can pledge the assets of the Trust to secure payments of the borrowings. At September 30, 2016 and December 31, 2015 the reserve amount was $0;

        (d)   the Trustees will make cash distributions to the Unit holders in January, April, July and October of each year as discussed in Note 4; and

        (e)   the Trust will terminate upon the first to occur of the following events: (i) total future net revenues attributable to the Partnership's interest in the Royalty, as determined by independent petroleum engineers, as of the end of any year, are less than $1.2 million (assuming no further sales of any interests in the Royalty) or (ii) a decision to terminate the Trust by the affirmative vote of Unit holders representing a majority of the Units. Future net revenues attributable to the Royalty were estimated at approximately $1.9 million (unaudited) as of November 1, 2015. Such future net revenues include projected reserves attributable to the four wells drilled by Arena Offshore, LP ("Arena") but did not include capital expenditures attributable to the redevelopment of Eugene Island 339. Upon termination of the Trust, in accordance with the Trust Agreement, the Corporate Trustee (as defined below) would sell for cash all assets held in the Trust estate and make a final distribution to the Unit holders of any funds remaining, after all Trust liabilities had been satisfied.

(1) Trust Organization (Continued)

        On October 27, 2011, the Partnership sold 20% of the Original Royalty (or 5% of 8/8ths) for gross proceeds of $1,600,000. See Note 3.

        On October 31, 2013, the Partnership consummated the sale of 25% of its remaining interest in the Original Royalty (or 5% of 8/8ths) for gross proceeds of $1,200,000. See Note 3.

        On June 24, 2016, the Partnership consummated the sale of all of its remaining interest in the Original Royalty (or 15% of 8/8ths) owned by the Partnership. As a result of consummation of the sale, the Partnership no longer owns any overriding royalty interest in the Royalty Properties. See Note 3.

        The Trust is currently administered by The Bank of New York Mellon Trust Company, N.A. (the "Corporate Trustee"), which succeeded JPMorgan Chase Bank, N.A. as the corporate trustee, effective October 2, 2006 pursuant to an agreement under which The Bank of New York acquired substantially all of the corporate trust business of JPMorgan Chase (formerly known as The Chase Manhattan Bank), and Gary C. Evans, Thomas H. Owen, Jr., and Jeffrey S. Swanson (the "Individual Trustees"), as trustees (collectively, the "Trustees").

        The Trustees, including the Corporate Trustee, have no authority over, have not evaluated and make no statement concerning, the internal control over financial reporting of any of the owner or owners of the Royalty Properties (the "Working Interest Owners").

(2) Basis of Accounting and Going Concern

        The accompanying unaudited financial information has been prepared by the Corporate Trustee. The accompanying financial information is prepared on a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America ("GAAP"). The Trustees believe that the information furnished reflects all adjustments that are, in the opinion of the Trustees, necessary for a fair presentation of the results for the interim periods presented. Such adjustments are of a normal and recurring nature. The financial information should be read in conjunction with the financial statements and notes thereto included in the Trust's Annual Report on Form 10-K for the year ended December 31, 2015.

        Overriding Royalty Interest.    The Trust uses the modified cash basis of accounting to report Trust receipts from the overriding royalty and payments of expenses incurred. Actual cash distributions to the Trust were made based on the terms of the conveyance that created the Trust's overriding royalty interest. Prior to the Royalty Sales (as defined in Note 3), the overriding royalty interest entitled the Trust to receive revenues (oil, gas and natural gas liquid sales) less expenses (the amount by which all royalties, lease operating expenses including well workover costs, production and property taxes, post-production costs including plugging and abandonment, and producing overhead of the underlying properties) multiplied by the Partnership's interest in the Original Royalty. The Original Royalty initially represented a 25% net profits interest but after the Royalty Sales, the Partnership no longer owns any overriding interest in the Royalty properties. Actual cash receipts would vary due to timing

TEL OFFSHORE TRUST

NOTES TO CONDENSED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

(2) Basis of Accounting and Going Concern (Continued)

delays of cash receipts from the property operators or purchasers and due to wellhead and pipeline volume balancing agreements or practices.

        Modified Cash Basis of Accounting.    The condensed financial statements of the Trust, as prepared on a modified cash basis, reflect the Trust's assets, liabilities, Trust corpus, earnings and distributions, as follows:

(a)

Royalty income from the overriding royalty interest was recorded when received, including the effect of overtaken or undertaken positions and negative or positive adjustments, by the Corporate Trustee on the last business day of each calendar quarter. In addition, Royalty income included amounts related to funds deposited or released from the Special Cost Escrow account—see (d);



(b)

Trust general and administrative expenses (which include the Trustee's fees as well as accounting, engineering, legal, and other professional fees) are recorded when paid by the Trust rather than when incurred;



(c)

Cash reserves for Trust expenses may be established by the Trustee for certain expenditures that would not be recorded as contingent liabilities under GAAP;



(d)

The funds deposited or released from the Special Cost Escrow account were recorded at the time of payment or receipt. The Special Cost Escrow account is an account of the Working Interest Owners and is not reflected in the condensed financial statements of the Trust;



(e)

Amortization of the investment in overriding royalty interest was calculated based on the units-of-production method. Such amortization was charged directly to Trust corpus and did not affect distributable income; and



(f)

Proceeds from loans used to pay for Trust expenses are charged directly to Trust corpus.

        This manner of reporting income and expenses is considered to be the most meaningful because the quarterly distributions to Unit holders are based on net cash receipts received from the Working Interest Owners. The condensed financial statements of the Trust differ from condensed financial statements prepared in accordance with GAAP, because, under such principles, Royalty income and Trust general and administrative expenses for a quarter would be recognized on an accrual basis. In addition, amortization of the net overriding royalty interest, calculated on a units-of-production basis, was charged directly to Trust corpus since such amount did not affect distributable income. This comprehensive basis of accounting other than GAAP corresponds to the accounting permitted for royalty trusts by the U.S. Securities and Exchange Commission, as specified by Staff Accounting Bulletin Topic 12:E, Financial Statements of Royalty Trusts.

        Oil and Gas Reserves.    The proved oil and gas reserves for the underlying properties have been estimated by independent petroleum engineers. Reserve engineering is a subjective process that is dependent upon the quality of available data and the interpretation thereof. Estimates by different

5

TEL OFFSHORE TRUST

NOTES TO CONDENSED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

(2) Basis of Accounting and Going Concern (Continued)

engineers often vary, sometimes significantly. In addition, physical factors such as the results of drilling, testing and production subsequent to the date of an estimate, as well as economic factors such as changes in product prices and production costs, may justify revision of such estimates. Accordingly, oil and gas quantities ultimately recovered and the timing of production may be substantially different from estimates.

        The standardized measure of discounted future net cash flows is prepared using assumptions made pursuant to FASB and SEC guidelines. Such assumptions include using average fiscal-year oil and gas prices (calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month reporting period) and year-end costs for estimated future production expenditures. Discounted future net cash flows are calculated using a 10% discount rate. Changes in any of these assumptions could have a significant impact on the standardized measure. The standardized measure does not necessarily result in an estimate of the current fair market value of proved reserves.

        Amortization of Overriding Royalty Interest.    The Trust amortized the investment in overriding royalty interest using the units-of-production method. The Trust's rate of recording amortization was dependent upon the estimates of total proved reserves, which incorporated various assumptions and future projections. If the estimates of total proved reserves declined significantly, the rate at which the Trust recorded amortization expense would have increased, reducing Trust corpus. Such a decline in reserves may result from lower commodity prices, which may make it uneconomic to produce from higher cost fields. As a result of the 2016 Royalty Sale, the Trust no longer holds any investment in the overriding royalty interest and there will be no further amortization.

        Impairment of Investment in Overriding Royalty Interest.    The Trust reviewed overriding royalty interests in oil and gas properties for possible impairment whenever events or circumstances indicated the carrying amount of the asset may not be recoverable. If there was an indication of impairment, the Trust prepared an estimate of future cash flows (undiscounted and without interest charges) expected to result from the use of the asset and its eventual disposition. If these cash flows were less than the carrying amount of the asset, an impairment loss was recognized to write down the asset to its estimated fair value. Preparation of estimated expected future cash flows is inherently subjective and was based on the Corporate Trustee's best estimate of assumptions concerning expected future conditions. As a result of the 2016 Royalty Sale, the Trust no longer holds any investment in the overriding royalty interest and there will be no further impairments.

        Cash and Cash Equivalents.    Cash and cash equivalents include all highly liquid short-term investments with original maturities of three months or less.

        Restricted Cash.    Restricted cash reported on the Condensed Statement of Assets, Liabilities and Trust Corpus consists of (i)  proceeds received by the Trust from the 2016 Royalty Sale and (ii) the distribution received by the Trust as a result of the Cox Oil Sale (as defined in Note 6). The proceeds from the 2016 Royalty Sale are required to be held in a segregated account pending resolution of the

(2) Basis of Accounting and Going Concern (Continued)

Probate Proceeding (as defined in Note 6). The distribution received in connection with the Cox Oil Sale (as defined in Note 6) is also being withheld by the Trust pending resolution of the Probate Proceeding.

        Reserve for future Trust expenses.    Represents cash reserves for future Trust expenses established by the Trustee. The changes in reserves for future Trust expenses include both changes of amounts deemed necessary by the Trustees and related distributions, as well as amounts paid from the reserve during periods when the Trust has insufficient income to pay Trust expenses. See Note 6.

        Proceeds from Sale of Overriding Royalty.    The Trust recorded proceeds from the sale of overriding royalty interests when received.

        Special Cost Escrow account.    The Special Cost Escrow account was established for future costs to be incurred to plug and abandon wells, dismantle and remove platforms, pipelines and other production facilities, and for the estimated amount of future capital expenditures on the Royalty Properties. The funds previously held in the Special Cost Escrow account were not reflected in the condensed financial statements of the Trust. However, funds deposited to or released from the Special Cost Escrow account were included in Royalty income. See Note 5.

        Use of Estimates.    The preparation of financial statements requires the Trustees to make use of estimates and assumptions that affect amounts reported in the condensed financial statements as well as certain disclosures. Actual results could differ from those estimates.

        Recent Accounting Pronouncements.    There were no accounting pronouncements issued during the three months ended September 30, 2016, applicable to the Trust or its condensed financial statements.

        Going Concern.    The accompanying condensed financial statements have been prepared assuming that the Trust will continue as a going concern. Financial statements prepared on the going concern basis assume the realization of assets and the settlement of liabilities in the normal course of business. During the first quarter of 2016, the Trust received $713 in Royalty income from Fieldwood Energy Offshore LLC ("Fieldwood"), the operator of Eugene Island 342. In addition, as a result of the sale by Chevron of its interest in Ship Shoal 182/183 effective August 1, 2015 to Cox Oil Offshore, L.L.C. ("Cox Oil"), the Trust received a distribution of $116,429 in May 2016. As a result of the Partnership's sale of the remaining Royalty in the 2016 Royalty Sale (as defined in Note 3 below), the Trust will not be receiving any further Royalty income and the proceeds from such sale are required to be held in a segregated interest bearing account, which is presented as Cash-Restricted in the Condensed Statements of Assets, Liabilities and Trust Corpus, pending a subsequent court order from the Court (as defined in Note 6). The Trust will not make any distribution of the proceeds from the 2016 Royalty Sale to Unit holders until it receives a subsequent order from the Court or the Remaining Matters (as defined in Note 6) are otherwise settled. In addition, the Trust may refrain from making any distribution of such proceeds until after the expiration of the audit period provided for in the conveyance document for the 2016 Royalty Sale, which expires on December 29, 2016. The lack of Net Proceeds and the inability to maintain adequate cash reserves raise substantial doubt about the Trust's

(2) Basis of Accounting and Going Concern (Continued)

ability to continue as a going concern. The condensed financial statements do not include any adjustments that might result from the outcome of the Probate Proceeding.

(3) Net Overriding Royalty Interest

        The Original Royalty entitled the Trust to its share (99.99%) of 25% of the Net Proceeds attributable to the Royalty Properties. The Conveyance, dated January 1, 1983, provided that the Working Interest Owners would calculate, for each period of three months commencing the first day of February, May, August and November, an amount equal to 25% of the Net Proceeds from their oil and gas properties for the period. Generally, "Net Proceeds" means the amount received by the Working Interest Owners from the sale of minerals from the Royalty Properties less operating and capital costs incurred, management fees and expense reimbursements owing to the Managing General Partner of the Partnership, applicable taxes other than income taxes, and the Special Cost Escrow account. The Special Cost Escrow account was established for the future costs to be incurred to plug and abandon wells, dismantle and remove platforms, pipelines and other production facilities, and for the estimated amount of future capital expenditures on the Royalty Properties. Net Proceeds did not include amounts received by the Working Interest Owners as advance gas payments, "take-or-pay" payments or similar payments unless and until such payments were extinguished or repaid through the future delivery of gas.

        On October 27, 2011, the Trust issued a press release announcing that the Partnership had consummated the sale (the "2011 Royalty Sale") of 20% of the Original Royalty (or 5% of 8/8ths). The 2011 Royalty Sale was made to RNR Production, Land and Cattle Company, Inc. ("RNR Production") on October 27, 2011, though the assignment was effective as of August 1, 2011. Refer to Note 6 for further discussion of the 2011 Royalty Sale.

        On October 31, 2013, the Trust issued a press release announcing that the Partnership had consummated the sale (the "2013 Royalty Sale") of 25% of its remaining interest in the Original Royalty (or 5% of 8/8ths). The 2013 Royalty Sale to RNR Production closed on October 31, 2013, though the assignment was effective as of August 1, 2013. Refer to Note 6 for further discussion of the 2013 Royalty Sale.

        On June 27, 2016, the Trust issued a press release announcing that the Partnership had consummated the sale (the "2016 Royalty Sale" and, together with the 2011 Royalty Sale and the 2013 Royalty Sale, the "Royalty Sales") of all of its remaining interest in the Original Royalty (60% or 15% of 8/8ths). As a result of consummation of the 2016 Royalty Sale, the Partnership no longer owns any Royalty in the Royalty Properties. The 2016 Royalty Sale was made to Arena Energy, LP and closed on June 24, 2016, but was effective as of February 1, 2016. The 2016 Royalty Sale generated $1,830,000 in gross proceeds and occurred as part of the previously announced formal auction process for the overriding royalty interest. The Trust received a distribution of approximately $1,756.624, representing 99.99% of the net proceeds from the Royalty Sale of $1,756,800 in July 2016. See Note 6 for a further discussion of the 2016 Royalty Sale.

(3) Net Overriding Royalty Interest (Continued)

        On the last business day of each calendar quarter prior to August 1, 2011, the Working Interest Owners were to pay to the Partnership 25% of the Net Proceeds for the immediately preceding Quarterly Period; however, (i) as a result of the 2011 Royalty Sale, on the last business day of each calendar quarter after August 1, 2011 and prior to August 1, 2013, the Working Interest Owners were to pay to the Partnership 20% of the Net Proceeds for the immediately preceding Quarterly Period (ii) as a result of the 2013 Royalty Sale, on the last business day of each calendar quarter after August 1, 2013, the Working Interest Owners were to pay to the Partnership 15% of the Net Proceeds for the immediately preceding Quarterly Period and (iii) as a result of the 2016 Royalty Sale, from and after February 1, 2016, the Working Interest Owners are no longer required to pay to the Partnership any Net Proceeds. A Quarterly Period is each period of three months commencing on the first day of February, May, August and November. In turn, the Partnership distributed funds to its partners on the last business day of each calendar quarter. Cash distributions from the Trust, if any, were made in January, April, July and October of each year, and were payable to Unit holders of record as of the last business day of each calendar quarter. The financial and operating information included in this Form 10-Q for the three and nine months ended September 30, 2016 and September 30, 2015 represents financial and operating information with respect to the Royalty Properties for the immediately preceding months of November, December, January, February, March, April, May, June and July. Income received pursuant to the Partnership's overriding royalty interest was recorded by the Trust on a cash basis, when it was received by the Trust from the Partnership.

(4) Distributions to Unit Holders

        In accordance with the provisions of the Trust Agreement, generally all Net Proceeds received by the Trust, net of Trust general and administrative expenses and any cash reserves established for the payment of contingent or future obligations of the Trust, are distributed quarterly to the Unit holders. These distributions are referred to as "distributable income." The amounts distributed, if any, are determined on a quarterly basis and are payable to Unit holders of record as of the last business day of each calendar quarter. Cash distributions, when available, are made in January, April, July and October and include interest earned from the quarterly record date to the date of distribution.

        Production ceased at Eugene Island 339 and Ship Shoal 182 and 183 following damages inflicted by Hurricane Ike in September 2008. Future Net Proceeds took into account the Trust's share of project costs and other related expenditures that were not covered by insurance of the operator of the Royalty Properties. On December 19, 2008, the Trust announced its fourth quarter distribution of approximately $0.7 million, which was paid on January 9, 2009. The funds available for the fourth quarter distribution were severely negatively impacted by lower production as a result of shutdowns and damage to producing assets because of Hurricane Ike. On March 25, 2009, the Trust announced that there would be no trust distribution for the first quarter of 2009, and the Trust has not made a distribution since January 9, 2009.

        The Trust currently holds the net proceeds from the 2016 Royalty Sale and remaining proceeds received as a result of the Cox Oil Sale (as defined in Note 6), a portion of such proceeds having been

(4) Distributions to Unit Holders (Continued)

used to pay certain expenses of the ad litem in the Probate Proceeding. The Trust will not make any distribution of these funds to Unit holders until it receives a subsequent order from the Court or the Remaining Matters are otherwise settled. In addition, the Trust may refrain from making any distribution of such proceeds until after the expiration of the audit period provided for in the conveyance document for the 2016 Royalty Sale, which expires on December 24, 2016.

(5) Special Cost Escrow Account

        The Special Cost Escrow is an account of the Working Interest Owners, and it is described herein for informational purposes only. The Conveyance provides for reserving funds for estimated future "Special Costs" of plugging and abandoning wells, dismantling platforms and other costs of abandoning the Royalty Properties, as well as for the estimated amount of future drilling projects and other capital expenditures on the Royalty Properties. Deposits into this account reduce current distributions and are placed in an escrow account and invested in short-term certificates of deposit. Such account is herein referred to as the "Special Cost Escrow" account. As of September 30, 2016, $1,000 remained in the Special Cost Escrow account. The funds held in the Special Cost Escrow account are not reflected in the condensed financial statements of the Trust. All of the Partnership's rights and obligations with respect to the Special Cost Escrow were assigned in connection with the Royalty Sales.

(6) Reserve For Future Trust Expenses; Probate Proceeding

        Historically, the Trust generally maintained a cash reserve, equal to approximately three times the average annual expenses of the Trust during each of the then past three years, to provide for future administrative expenses in connection with the winding up of the Trust. However, as a result of the damage inflicted upon certain of the Royalty Properties by Hurricane Ike in September 2008, the Trust has not received sufficient Net Proceeds to maintain the reserve at such level. As of September 30, 2016 and December 31, 2015 the reserve amount was $0.

        During the first quarter of 2016, the Trust received Royalty income of $713 attributable to Eugene Island 342. On April 15, 2016, but effective as of August 1, 2015, Chevron conveyed certain oil and gas properties to Cox Oil, including Chevron's interest in Ship Shoal 182/183 that was subject to the Royalty (the "Cox Oil Sale"). Any Net Proceeds from Cox Oil attributable to Ship Shoal 182/183 are not subject to offset by Chevron against the undistributed net loss carry forward attributable to the Royalty Properties held by Chevron. As a result of the August 1, 2015 effective time and the Ship Shoal 182/183 properties not being subject to the undistributed net loss carry forward, the Trust received a distribution from Cox Oil of $116,429 in May 2016. The Trust also received net proceeds of $1,756,624 from the 2016 Royalty Sale; however, the net proceeds from the 2016 Royalty Sale are not available to the Trust for the payment of costs and expenses pending the resolution of the Probate Proceeding. In addition, the remaining proceeds received as a result of the Cox Oil Sale are also being separately withheld and are not available to the Trust for the payment of costs and expenses unless approved by the ad litem pending the resolution of the Probable Proceeding. As a result of the 2016 Royalty Sale, the Trust will not receive any further Net Proceeds from the Royalty Properties. As of

(6) Reserve For Future Trust Expenses; Probate Proceeding (Continued)

September 30, 2016, including the proceeds from the 2015 Note (as defined below) and additional cash advances, the Trust's available cash was approximately $22,230. Based upon currently estimated expenditures, inclusive of the costs and expenses relating to the Probate Proceeding, it is anticipated that the Trust's available cash will be depleted during the fourth quarter of 2016. Following the depletion of the Trust's available cash, the Trustees will endeavor to cause the Trust to pay the administrative costs of the Trust in accordance with the Trust Agreement. There are no assurances that the Trust will be able to continue to pay its administrative expenses.

        Pursuant to the terms of the Trust Agreement, the Trustees are authorized to borrow funds, and pledge the assets of the Trust to secure payments of such borrowings, in the event that cash on hand is not sufficient to pay the liabilities of the Trust. In the event that the Trustees borrow funds to pay the liabilities of the Trust, no distributions may be made to the Unit holders until the indebtedness created by such borrowings has been paid in full. As discussed in Note 9, the Trustees borrowed, and may in the future borrow, funds from which a portion of the proceeds were, or may be, used to pay for Trust expenses.

        The Trust Agreement further provides that, if necessary to provide for the payment of specific liabilities of the Trust then due, the Trustees may without a vote of the Unit holders (a) sell all or a portion of the Trust's interest in the Partnership or any other assets of the Trust for such cash consideration as the Trustees shall deem appropriate, (b) exercise their rights under the Partnership Agreement to dissolve the Partnership, or (c) cause a sale by the Partnership of the overriding royalty interest owned by the Partnership.

        In connection with the 2011 Royalty Sale, the Trust received from the Partnership a distribution of approximately $1,485,851 and used such net proceeds solely for the payment of expenses of the Trust. In connection with the 2013 Royalty Sale, the Trust received from the Partnership a distribution of approximately $1,151,885 and used approximately $300,000 of the net proceeds received in October 2013 to repay the Trust's indebtedness under a previous note payable to BONYM and used the remaining net proceeds solely for the payment of expenses of the Trust. See Note 3 for more information about the Royalty Sales.

        In March 2014, the Trustees unanimously determined to suspend future payments of fees to the Trustees effective as of January 1, 2014, until a date to be determined in the future by the Trustees. As of September 30, 2016, the amount of such fees was approximately $471,470 in the aggregate. Such suspended fees will be recorded as an expense of the Trust when invoiced by the Trustees and paid.

        On July 10, 2014, the Trustees filed a Petition for Modification and Termination of the Trust (the "Petition") with the Probate Court of Travis County, Texas (the "Court"). The Petition requested that the Court modify the Trust Agreement to (1) allow for the termination of the Trust by a court order, and (2) allow the Trustees, as necessary to fulfill the purposes of the Trust and without Unit holder approval to (a) sell all or any portion of the Trust's interests in the Partnership or any other assets of the Trust, (b) exercise their rights to dissolve the Partnership, or (c) cause the Partnership to sell the Royalty. The goals in filing such probate proceeding (the "Probate Proceeding") were to permit the

Trustees to direct the Partnership to sell the Royalty; to distribute the net proceeds resulting from such sale, after payment of the Trust's liabilities, to the Unit holders; and, to, thereafter terminate the Partnership and the Trust. The Trust has completed the process of serving the Petition on the Trust's Unit holders. The Court appointed an attorney ad litem to represent any Unit holders that were not personally served. The Court appointed attorney ad litem filed a Counterclaim against the Trust on November 16, 2015 requesting (1) an order to sell all of the Royalty, and (2) an accounting of the general and administrative expenses of the Trust from 2008 through the present.

        The Probate Proceeding was set for trial on January 15, 2016. Prior to trial, the attorney ad litem filed a Motion to Sever asking the Court to sever all matters related to the requested modification of the Trust and the sale of Trust assets, as plead for, in part, in the petition originally filed by the Trustees and in the attorney ad litem's Counterclaim, into a separate cause to proceed to trial. The attorney ad litem also filed a Motion for Continuance requesting that the Court continue the trial of all remaining matters, including the attorney ad litem's request for an accounting and the issues concerning the termination of the Trust, to a later date (the "Remaining Matters"). Prior to calling the case to trial, the Court granted the attorney ad litem's Motion to Sever and Motion for Continuance, severed the matters related to the modification of the Trust and the sale of Trust assets ("Severed Proceeding"), and continued the Remaining Matters to a later date. The Severed Proceeding has been assigned Cause No. C-1-PB-16-000096 and is styled In re: TEL Offshore Trust.

        The Severed Proceeding proceeded to trial before the Court on January 15, 2016. At trial, the Court entered a Final Judgment and Order (the "Order") granting the Trustees' request that the Trust Agreement be modified to permit the Trustees to direct the Partnership to sell the remaining overriding royalty interest held by the Partnership as soon as reasonably possible and granting the ad litem's request to sell all of the Royalty, notwithstanding any requirements of the Trust Agreement to the contrary. Thereafter, the Court ordered that the Trustees direct the Partnership to sell all of the Royalty owned by the Partnership on or before May 1, 2016. On April 25, 2016, the Court approved an extension of the May 1, 2016 deadline to June 30, 2016.

        On August 17, 2016, the attorney ad litem filed a Second Amended Answer and First Amended Counterclaim seeking an accounting and asserting, among other causes of action, that the Trustees have breached their fiduciary duties to the beneficiaries of the Trust. The Remaining Matters were originally set for trial on November 7, 2016. Trustees filed a motion for continuance of the Remaining Matters and a hearing for such continuance occurred on September 14, 2016. At the hearing, the Court granted the Trustees' motion for continuance of the Remaining Matters and scheduled the trial for June 12, 2017. There can be no assurances as to the outcome of the Remaining Matters and whether the Court will grant the requested relief, and if such relief is granted, when such actions will be completed.

        On June 27, 2016, the Trust issued a press release announcing that the Partnership had consummated the 2016 Royalty Sale on June 24, 2016. The sale was made in accordance with the Order pursuant to which the Court ordered that the Trustees of the Trust direct the Partnership to sell all of the royalty interests owned by the Partnership. In connection with the 2016 Royalty Sale the Trust

(6) Reserve For Future Trust Expenses; Probate Proceeding (Continued)

received a distribution of approximately $1,756.624. Due to the Remaining Matters, the Trust must hold the net proceeds in a segregated account until the Court's final resolution of the Remaining Matters. Distributions may be made from such segregated account for the payment of Trust expenses, which may include the payment of the ad litem's expenses, with the approval of the Court. Any final disposition of the remaining net proceeds will be made in accordance with the final resolution of the Remaining Matters. In addition, the Trust may refrain from making any distribution of the net proceeds received from the 2016 Royalty Sale until the expiration of the audit period provided for in the conveyance document for the 2016 Royalty Sale, which expires on December 24, 2016.

(7) Federal Income Tax Matters

        The IRS has ruled that the Trust is a grantor trust and that the Partnership is a partnership for federal income tax purposes. Thus, the Trust will incur no federal income tax liability and each Unit holder will be treated as owning an interest in the Partnership.

(8) Related Party Transactions

        Each of the Working Interest Owners owned interests, for its own account, in leases that were in the same area as leases in which the Partnership had previously held an interest. Such relationships may have given rise to potential conflicts of interests in, among other things, the operation of such leases and in the acquisition and operation of any drainage leases acquired by a Working Interest Owner for its own account. Additionally, the Working Interest Owners and their affiliates were not prohibited from purchasing oil and gas produced from or attributable to any leases in which the Partnership had an interest.

        Crude oil sales to Chevron Corporation accounted for 0% and 100% of crude oil revenues from the Royalty Properties for the three and nine months ended September 30, 2016 and 2015, respectively. Sales to Chevron Corporation accounted for 0% and 100% of total gas revenues from the Royalty Properties during the three and nine months ended September 30, 2016 and 2015, respectively.

        The Trust's share of Royalty income was reduced by approximately $0 and $13,891 for each of the three months ended September 30, 2016 and September 30, 2015, respectively, and $11,644 and $43,457 for each of the nine months ended September 30, 2016 and September 30, 2015, respectively, for management fees paid to the Working Interest Owners as reimbursement for expenses incurred by them on behalf of the Trust. The aggregate amount of management fees paid to the Working Interest Owners was calculated as 3% of the Trust's share of the sum of revenues, production expenses and capital expenditures attributable to the Royalty Properties in each of the periods above.

(9) Note Payable

        On October 1, 2014, The Bank of New York Mellon made an advance to the Trust in the amount of $363,000, and The Bank of New York Mellon Trust Company, N.A., in its capacity as corporate trustee, as the borrower, entered into a Demand Promissory Note (the "2014 Note") with BONYM,

(9) Note Payable (Continued)

relating to the unsecured $363,000 advance, which evidenced an extension of credit for borrowed money authorized under Section 6.08 of the Trust Agreement. The 2014 Note provided for interest at the rate of one-half percent (0.5%) per annum. Pursuant to the terms of the 2014 Note, all amounts outstanding under the 2014 Note were scheduled to be due and payable in cash on the earliest to occur of (i) the date written demand for payment is made by BONYM or (ii) December 31, 2015. The Trust could prepay any outstanding principal and accrued and unpaid interest under the 2014 Note, in whole or in part, at any time without penalty. In addition to the 2014 Note, through September 25, 2015, BONYM made additional cash advances in the amount of $209,885 to the Trust for the payment of its liabilities and expenses, primarily in connection with the Probate Proceeding.

        On September 25, 2015, BONYM made an additional advance to the Trust in the amount of $484,000, and the Corporate Trustee, as the borrower, has entered into a Renewal Demand Promissory Note (the "2015 Note") with BONYM, in the original principal amount of $1,056,885 relating to (i) the unsecured $484,000 advance, (ii) the renewal and extension of the indebtedness originally evidenced by the 2014 Note in the original principal amount of $363,000, and (iii) previous advances in the amount of $209,885 made by BONYM on behalf of the Trust. The 2015 Note bears interest at the rate of one-half percent (0.5%) per annum. Pursuant to the terms of the 2015 Note, all amounts outstanding under the 2015 Note, including accrued and unpaid interest, will be due and payable in cash on the earliest to occur of (i) the date written demand for payment is made by BONYM or (ii) December 31, 2016. In addition, the accrued and unpaid interest remaining due from the 2014 Note in the amount of $1,790 is due and payable concurrently with the payment of the 2015 Note. The Trust may prepay any outstanding principal and accrued and unpaid interest under the 2015 Note, in whole or in part, at any time without penalty.

        In addition to the 2015 Note, through September 30, 2016, BONYM has made additional advances in the amount of $68,224 to the Trust for the payment of its liabilities and expenses, primarily in connection with the Probate Proceeding.

Item 2.    Trustee's Discussion and Analysis of Financial Condition and Results of Operations.

Overview

        The TEL Offshore Trust, which we refer to herein as the "Trust," was created under the laws of the State of Texas in 1983 and maintains its offices at the office of The Bank of New York Mellon Trust Company, N.A., whom we refer to as the "Corporate Trustee," 919 Congress Avenue, Suite 500, Austin, Texas 78701. The telephone number of the Corporate Trustee is (512) 236-6599. Gary C. Evans, Thomas H. Owen, Jr. and Jeffrey S. Swanson serve as individual trustees of the Trust and are referred to herein as the "Individual Trustees." The Individual Trustees and the Corporate Trustee may be referred to hereinafter collectively as the "Trustees."

        The Corporate Trustee does not maintain a website for filings by the Trust with the U.S. Securities and Exchange Commission, which we refer to herein as the "SEC." Electronic filings by the Trust with the SEC are available free of charge through the SEC's website at www.sec.gov. The Trust will also provide paper copies of its recent filing free upon request to the Corporate Trustee.

        The principal asset of the Trust consists of a 99.99% interest in the TEL Offshore Trust Partnership, which we refer to herein as the "Partnership." Chevron U.S.A., Inc., or "Chevron," owns the remaining .01% interest in the Partnership and is the Managing General Partner of the Partnership. Until October 27, 2011, the Partnership owned 100% of an overriding royalty interest equivalent to a 25% net profits interest (the "Original Royalty"), in certain oil and gas properties, which we refer to herein as the "Royalty Properties," located offshore Louisiana. The term "Original Royalty" shall refer to the initial 25% net profits interest in the Royalty Properties and the term "Royalty" shall refer to the applicable net profits interest held from time to time by the Partnership following the Royalty Sales (as defined below).

        On June 27, 2016, the Trust issued a press release announcing that the Partnership had consummated the sale of all of its remaining interest in the Original Royalty (60% or 15% of 8/8ths) (the "2016 Royalty Sale"). The 2016 Royalty Sale was made to Arena Energy, LP and closed on June 24, 2016, but was effective as of February 1, 2016. Due to the effective time of the 2016 Royalty Sale, the Trust no longer had any interest in, or any operating and financial results attributable to, the Royalty or the Royalty Properties as of February 1, 2016. As a result, the Trust has not provided any additional explanation for the corresponding decreases in revenues and production under "—Three Months Ended September 30, 2016 and 2015" below.

Liquidity and Capital Resources

        Prior to the sale of the remaining Royalty held by the Partnership in June 2016, the Trust's primary source of liquidity and capital had been the Royalty income received from its share of the Net Proceeds from the Royalty Properties. Generally, "Net Proceeds" means the amounts received by the owner or owners of the Royalty Properties (the "Working Interest Owners") from the sale of minerals from the Royalty Properties less operating and capital costs incurred, management fees and expense reimbursements owing to the Managing General Partner of the Partnership, applicable taxes other than income taxes, and the Special Cost Escrow account. The Special Cost Escrow account, as more fully detailed in Note 5 to the condensed financial statements, was established for the future costs to be incurred to plug and abandon wells, dismantle and remove platforms, pipelines and other production facilities, and for the estimated amount of future capital expenditures on the Royalty Properties. Net Proceeds did not include amounts received by the Working Interest Owners as advance gas payments,

15

---

"take- or-pay" payments or similar payments unless and until such payments were extinguished or repaid through the future delivery of gas.

        During the first quarter of 2016, the Trust received Royalty income of $713 attributable to Eugene Island 342 and in the fourth quarter of 2015, the Trust received $1,316 of Royalty income attributable to Eugene Island 342. The Trust had not received any distributions of Net Proceeds from Chevron, as operator of the Royalty Properties, since December 2008. On April 15, 2016, but effective as of August 1, 2015, Chevron conveyed certain oil and gas properties to Cox Oil Offshore, L.L.C. ("Cox Oil"), including Chevron's interest in Ship Shoal 182/183 that was subject to the Royalty (the "Cox Oil Sale"). Any Net Proceeds from Cox Oil attributable to Ship Shoal 182/183 are not subject to offset by Chevron against the undistributed net loss carry forward attributable to the Royalty Properties held by Chevron. As a result of the August 1, 2015 effective time and the Ship Shoal 182/183 properties not being subject to the undistributed net loss carry forward, the Trust was entitled to receive a distribution from Cox Oil of $116,429. The Trust received the distribution in May 2016 and as a result, the undistributed net loss carry forward attributable to the Royalty Properties increased by $116,429 from $524,335, as of January 31, 2016, to $640,764. Despite the receipt of such funds, as long as the Trust has outstanding indebtedness, no distributions may be made by the Trust to the Unit holders. As a result of the 2016 Royalty Sale, the Trust will not receive any further Net Proceeds from the Royalty Properties.

        Because of the lack of Net Proceeds, the Trust has in the past not had sufficient cash flow to pay expenses on a current basis and as described below, the Trust has been required to borrow funds and to cause the Partnership to sell part of the Original Royalty in order to pay Trust expenses. As of September 30, 2016, including the proceeds from the 2015 Note (as herein defined), the previous cash advances from The Bank of New York Mellon ("BONYM") included in the principal amount of the 2015 Note and subsequent cash advances by BONYM, the Trust's unrestricted cash was approximately $22,230. Based upon currently estimated expenditures, inclusive of the costs and expenses relating to the Probate Proceeding (as defined below), it is anticipated that the Trust's available cash will be depleted in the fourth quarter of 2016. Following the depletion of the Trust's available cash, the Trustees will endeavor to cause the Trust to pay the administrative costs of the Trust in accordance with the Trust Agreement. There are no assurances that the Trust will be able to continue to pay its administrative expenses.

        The Trust Agreement provides that, if necessary to provide for the payment of specific liabilities of the Trust then due, the Trustees may without a vote of the Unit holders (a) sell all or a portion of the Trust's interest in the Partnership or any other assets of the Trust for such cash consideration as the Trustees shall deem appropriate, (b) exercise their rights under the Partnership Agreement to dissolve the Partnership, or (c) cause a sale by the Partnership of the overriding royalty interest owned by the Partnership. Additionally, the Trustees, on behalf of the Trust, were authorized to borrow funds, and pledge the assets of the Trust to secure payments of such borrowings, in the event that cash on hand was not sufficient to pay the liabilities of the Trust. In the event that the Trustees borrows funds to pay the liabilities of the Trust, no distributions will be made to the Unit holders until the indebtedness created by such borrowings has been paid in full.

        On October 27, 2011, the Trust issued a press release announcing that the Partnership had consummated the sale (the "2011 Royalty Sale") of 20% of the Original Royalty (or 5% of 8/8ths), which generated $1,600,000 in gross proceeds and occurred as part of a formal auction process for the Partnership's overriding royalty interest in the Royalty Properties. The Trust received from the

16

---

Partnership a distribution of approximately $1,485,851, representing 99.99% of the net proceeds from the sale of $1,486,000. The 2011 Royalty Sale was made to RNR Production, Land and Cattle Company, Inc. ("RNR Production") on October 27, 2011, though the assignment was effective as of August 1, 2011.

        On October 31, 2013, the Trust issued a press release announcing that the Partnership had consummated the sale (the "2013 Royalty Sale") of 25% of its remaining interest in the Original Royalty (or 5% of 8/8ths), which generated $1,200,000 in gross proceeds and occurred as part of a formal auction process for the Partnership's remaining overriding royalty interest in the Royalty Properties. The Trust received from the Partnership a distribution of approximately $1,151,885, representing 99.99% of the net proceeds from the sale of $1,152,000. The 2013 Royalty Sale was made to RNR Production on October 31, 2013, though the assignment was effective as of August 1, 2013. The Trust used approximately $300,000 of the net proceeds received in October 2013 to repay the Trust's indebtedness under a previous note payable to BONYM and used the remaining net proceeds solely for the payment of expenses of the Trust.

        In March 2014, the Trustees unanimously determined to suspend future payments of fees to the Trustees effective as of January 1, 2014, until a date to be determined in the future by the Trustees. As of September 30, 2016, the accumulated amount of such suspended fees was approximately $414,918 in the aggregate. The cumulative suspended fees will be recorded as an expense of the Trust when invoiced by the Trustees and paid.

        On October 1, 2014, BONYM made a loan to the Trust in the amount of $363,000, and the Corporate Trustee, as the borrower, entered into a Demand Promissory Note (the "2014 Note") with BONYM, as lender, relating to the unsecured $363,000 advance, which evidenced an extension of credit for borrowed money authorized under Section 6.08 of the Trust Agreement. On September 25, 2015, BONYM made an additional advance to the Trust in the amount of $484,000 and the Corporate Trustee, as the borrower, entered into a Renewal Demand Promissory Note (the "2015 Note") with BONYM, as lender, relating to (i) the unsecured $484,000 advance, (ii) the renewal and extension of the 2014 Note, and (iii) previous advances in the amount of $209,885 made by BONYM on behalf of the Trust. The 2015 Note bears interest at the rate of one-half percent (0.5%) per annum. Pursuant to the terms of the 2015 Note, all amounts outstanding under the 2015 Note including accrued and unpaid interest will be due and payable in cash on the earliest to occur of (x) the date written demand for payment is made by BONYM or (y) December 31, 2016. The Trust may prepay any outstanding principal and accrued and unpaid interest under the 2015 Note, in whole or in part, at any time without penalty. In addition, the accrued and unpaid interest remaining due from the 2014 Note in the amount of $1,790 is due and payable concurrently with the payment of the 2015 Note. During the three months ended September 30, 2016, a portion of the proceeds from the 2014 Note, as renewed and extended by the 2015 Note, were used to pay Trust expenses.

        As indicated above, the Trustees have previously authorized the Trust to borrow funds and the Partnership to sell portions of the Original Royalty in an effort to pay the ongoing costs and expenses incurred by the Trust in fulfilling its obligations under the Trust Agreement. As a result of the ongoing costs and expenses of the Trust and the lack of any distributions or assurances of future distributions, on July 10, 2014, the Trustees filed a Petition for Modification and Termination of the Trust (the "Petition") with the Probate Court of Travis County, Texas (the "Court"). The Petition requested that the Court modify the Trust Agreement to (1) allow for the termination of the Trust by a court order, and (2) allow the Trustees, as necessary to fulfill the purposes of the Trust and without Unit holder

17

---

approval to (a) sell all or any portion of the Trust's interests in the Partnership or any other assets of the Trust, (b) exercise their rights to dissolve the Partnership, or (c) cause the Partnership to sell the Royalty. The goals in filing such probate proceeding (the "Probate Proceeding") were to permit the Trustees to direct the Partnership to sell the Royalty; to distribute the net proceeds resulting from such sale, after payment of the Trust's liabilities, to the Unit holders; and, to, thereafter terminate the Partnership and the Trust. The Trust has completed the process of serving the Petition on the Trust's Unit holders. The Court appointed an attorney ad litem to represent any Unit holders that were not personally served. The Court appointed attorney ad litem filed a Counterclaim against the Trust on November 16, 2015 requesting (1) an order to sell all of the Royalty, and (2) an accounting of the general and administrative expenses of the Trust from 2008 through the present.

        The Probate Proceeding was set for trial on January 15, 2016. Prior to trial, the attorney ad litem filed a Motion to Sever asking the Court to sever all matters related to the requested modification of the Trust and the sale of Trust assets, as plead for, in part, in the petition originally filed by the Trustees and in the attorney ad litem's Counterclaim, into a separate cause to proceed to trial. The attorney ad litem also filed a Motion for Continuance requesting that the Court continue the trial of all remaining matters, including the attorney ad litem's request for an accounting and the issues concerning the termination of the Trust, to a later date (the "Remaining Matters"). Prior to calling the case to trial, the Court granted the attorney ad litem's Motion to Sever and Motion for Continuance, severed the matters related to the modification of the Trust and the sale of Trust assets ("Severed Proceeding"), and continued the Remaining Matters to a later date. The Severed Proceeding has been assigned Cause No. C-1-PB-16-000096 and is styled In re: TEL Offshore Trust.

        The Severed Proceeding proceeded to trial before the Court on January 15, 2016. At trial, the Court entered a Final Judgment and Order (the "Order") granting the Trustees' request that the Trust Agreement be modified to permit the Trustees to direct the Partnership to sell the remaining overriding royalty interest held by the Partnership as soon as reasonably possible and granting the ad litem's request to sell all of the Royalty, notwithstanding any requirements of the Trust Agreement to the contrary. Thereafter, the Court ordered that the Trustees direct the Partnership to sell all of the Royalty owned by the Partnership through a sale to be conducted by EnergyNet.com, Inc. on or before May 1, 2016. On April 25, 2016, the Court approved an extension of the May 1, 2016 deadline to June 30, 2016.

        On August 17, 2016, the attorney ad litem filed a Second Amended Answer and First Amended Counterclaim seeking an accounting and asserting, among other causes of action, that the Trustees have breached their fiduciary duties to the beneficiaries of the Trust. The Remaining Matters were originally set for trial on November 7, 2016. Trustees filed a motion for continuance of the Remaining Matters and a hearing for such continuance occurred on September 14, 2016. At the hearing, the Court granted the Trustees' motion for continuance of the Remaining Matters and scheduled the trial for June 12, 2017. There can be no assurances as to the outcome of the Remaining Matters and whether the Court will grant the requested relief, and if such relief is granted, when such actions will be completed.

        On June 27, 2016, the Trust issued a press release announcing that the Partnership had consummated the 2016 Royalty Sale (the 2016 Royalty Sale, together with the 2011 Royalty Sale and the 2013 Royalty Sale, the "Royalty Sales"). The sale was made in accordance with the Order pursuant to which the Court ordered that the Trustees of the Trust direct the Partnership to sell all of the royalty interests owned by the Partnership.

18

---

        The 2016 Royalty Sale was made to Arena Energy, LP and closed on June 24, 2016, but was effective as of February 1, 2016. The 2016 Royalty Sale generated $1,830,000 in gross proceeds and occurred as part of the previously announced formal auction process for the overriding royalty interest. The Trust received a distribution of approximately $1,756.624, representing 99.99% of the net proceeds from the Royalty Sale of $1,756,800. Due to the Remaining Matters, the Trust must hold the net proceeds in a segregated account until the Court's final resolution of the Remaining Matters. The disposition of such net proceeds will be made in accordance with the final resolution of the Remaining Matters. In addition, the Trust may refrain from making any distribution of the net proceeds received from the 2016 Royalty Sale until the expiration of the audit period provided for in the conveyance document for the 2016 Royalty Sale, which expires on December 24, 2016.

        As a result of the 2016 Royalty Sale, the Trust no longer owns any interest in the Royalty and therefore will not receive any further distributions of Net Proceeds. Because of the Remaining Matters in the Probate Proceeding, the Trust must hold the net proceeds from the 2016 Royalty Sale in a segregated account until the final resolution of the Remaining Matters. In addition, the Trust has set aside the distribution received from Cox Oil until the final resolution of the Remaining Matters. Distributions may be made from such segregated account for the payment of Trust expenses, which may include the payment of the ad litem's expenses, with the approval of the Court. Any final disposition of the remaining net proceeds to Unit holders will be made in accordance with the final resolution of the Remaining Matters. As discussed above, as of September 30, 2016, including the proceeds from the 2015 Note and subsequent cash advances by BONYM, the Trust's unrestricted cash was $22,230. Based upon currently estimated expenditures, inclusive of the costs and expenses of the Probate Proceeding, it is anticipated that the Trust's available cash will be depleted during the fourth quarter of 2016. Following the depletion of the Trust's available cash, the Trustees will endeavor to cause the Trust to pay the administrative costs of the Trust in accordance with the Trust Agreement. There are no assurances that the Trust will be able to continue to pay its administrative expenses.

        The accompanying condensed financial statements have been prepared assuming that the Trust will continue as a going concern. Financial statements prepared on the going concern basis assume the realization of assets and the settlement of liabilities in the normal course of business. Because of the 2016 Royalty Sale, the Trust will not receive any further Net Proceeds from the Royalty Properties. The Trust currently holds the net proceeds from the 2016 Royalty Sale and remaining proceeds received as a result of the Cox Oil Sale, a portion of such proceeds having been used to pay certain expenses of the ad litem in the Probate Proceeding. The Trust will not make any distribution of these funds to Unit holders until it receives a subsequent order from the Court or the Remaining Matters are otherwise settled. In addition, the Trust may refrain from making any distribution of such proceeds until after the expiration of the audit period provided for in the conveyance document for the 2016 Royalty Sale, which expires on December 24, 2016. The lack of Net Proceeds and the inability to maintain adequate cash reserves raise substantial doubt about the Trust's ability to continue as a going concern. The condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty. See Note 2 to the condensed financial statements.

Special Cost Escrow Account

        The special cost escrow account is an account of the Working Interest Owners and it is described herein for informational purposes only. The Conveyance provides for the reserve of funds for estimated future "Special Costs" of plugging and abandoning wells, dismantling platforms and other costs of

19

---

abandoning the Royalty Properties, as well as for the estimated amount of future drilling projects and other capital expenditures on the Royalty Properties. Deposits into this account reduces current distributions and are placed in an escrow account and invested in short-term certificates of deposit. Such account is herein referred to as the "Special Cost Escrow" account. All of the Partnership's rights and obligations with respect to the Special Cost Escrow were assigned in connection with the Royalty Sales.

Three Months Ended September 30, 2016 and 2015

Royalty Trust Comparison

        Royalty income was $0 for each of the three months ended September 30, 2016 and 2015, respectively. As a result of the Royalty Sale, there were no gross proceeds for the underlying Royalty Properties attributable to the Trust for the production period of May, June and July 2016 attributable to the three months ended September 30, 2016. Gross proceeds for the underlying Royalty Properties exceeded development and production costs by $326,576, or $195,946 attributable to the Trust for the production period of May, June and July 2015 attributable to the three months ended September 30, 2015. The Net Proceeds were applied to reduce the accumulated excess cost carry forward, which represents the amount by which the aggregate development and production costs for the Royalty Properties since November 2008 have exceeded the related proceeds of the protection, and as a result there was no royalty income for the quarter ended September 30, 2015.

        General and administrative expenses for the Trust were $153,757 for the three months ended September 30, 2016 compared to $96,765 for the three months ended September 30, 2015. The increase is due, in part, to the costs associated with the Probate Proceeding.

        The reserve for future Trust expenses did not change from December 31, 2015 to September 30, 2016.

        There was no distributable income for each of the three months ended September 30, 2016 and September 30, 2015 and therefore no distributions to Unit holders.

        For the three months ended September 30, 2016 and September 30, 2015, the Trust had undistributed net income of $0 and $195,946, respectively, representing the Trust's portion of the undistributed net income of $0 and $1,306,304 associated with the Royalty Properties for the three months ended September 30, 2016 and 2015. The undistributed net income was applied to reduce the accumulated excess cost carry forward.

Underlying Properties Comparison

        The following financial and operational information has been based on information provided to the Corporate Trustee by the Managing General Partner. The Trustees had no control over these operations or internal controls relating to this information. The lack of revenues and production for the third quarter of 2016 are entirely attributable to the February 1, 2016 effective time for the 2016 Royalty Sale and, as a result, no additional disclosure on the 100% decrease in revenues and production in the third quarter of 2016 compared to the third quarter of 2015 is provided.

        Volumes and dollar amounts discussed below represented amounts recorded by the Working Interest Owners unless otherwise specified.

Item 4.    Controls and Procedures.

        Evaluation of disclosure controls and procedures.    The Corporate Trustee maintains disclosure controls and procedures designed to ensure that information required to be disclosed by the Trust in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and regulations. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by the Trust is accumulated and communicated by Chevron, as the Managing General Partner of the Partnership, and the Working Interest Owners to the Corporate Trustee of the Trust, and its employees who participate in the preparation of the Trust's periodic reports as appropriate to allow timely decisions regarding required disclosure.

        As disclosed in the Trust's Quarterly Report on Form 10-Q for the quarter ended March 31, 2016. Chevron notified the Corporate Trustee of errors in the working interest and net revenue interest used in calculating the net reserves attributable to the Royalty Properties and in preparing the net profits statements for the Royalty Properties and the Trust.

issues affecting the Trust's ability to timely file or submit reports required under the Securities Exchange Act of 1934, as amended. As of the end of the period covered by this report, the Corporate Trustee carried out an evaluation of the Trust's disclosure controls and procedures. Michael J. Ulrich, as Trust Officer of the Corporate Trustee, has concluded that the disclosure controls and procedures of the Trust were effective as of September 30, 2016.

        Due to the previous contractual arrangements of (i) the Trust Agreement, (ii) the Partnership Agreement and (iii) the rights of the Partnership under the Conveyance regarding information furnished by the Working Interest Owners, the Trustees relied on (A) information provided by the Working Interest Owners, including historical operating data, plans for future operating and capital expenditures, reserve information and information relating to projected production, (B) information from the Managing General Partner of the Partnership, including information that is collected from the Working Interest Owners, and (C) conclusions and reports regarding reserves by the Trust's independent reserve engineers. See Item 1A. Risk Factors "—The Trustees and the Unit holders had no control over the operation or development of the Royalty Properties and had little influence over operation or development" and "The Trustees rely upon the Working Interest Owners and Managing General Partner for information regarding the Royalty Properties" in the 2015 Form 10-K for a description of certain risks relating to these arrangements and reliance on and applicable adjustments to operating information when reported by the Working Interest Owners to the Corporate Trustee and recorded in the Trust's results of operation.

        Changes in Internal Control Over Financial Reporting.    During the three months ended September 30, 2016, there has been no change in the Trust's internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Trust's internal control over financial reporting. The Corporate Trustee notes for purposes of clarification that it had no authority over, and makes no statement concerning, the internal control over financial reporting of the Working Interest Owners or the Managing General Partner of the Partnership.

PART II—OTHER INFORMATION

Item 1.    Legal Proceedings.

        On July 10, 2014, the Trustees filed a Petition for Modification and Termination of the Trust (the "Petition") with the Probate Court of Travis County, Texas (the "Court"). The Petition requested that the Court modify the Trust Agreement to (1) allow for the termination of the Trust by a court order, and (2) allow the Trustees, as necessary to fulfill the purposes of the Trust and without Unit holder approval to (a) sell all or any portion of the Trust's interests in the Partnership or any other assets of the Trust, (b) exercise their rights to dissolve the Partnership, or (c) cause the Partnership to sell the Royalty. The goals in filing such probate proceeding (the "Probate Proceeding") were to permit the Trustees to direct the Partnership to sell the Royalty; to distribute the net proceeds resulting from such sale, after payment of the Trust's liabilities, to the Unit holders; and, to, thereafter terminate the Partnership and the Trust. The Trust has completed the process of serving the Petition on the Trust's Unit holders. The Court appointed an attorney ad litem to represent any Unit holders that were not personally served. The Court appointed attorney ad litem filed a Counterclaim against the Trust on November 16, 2015 requesting (1) an order to sell all of the Royalty, and (2) an accounting of the general and administrative expenses of the Trust from 2008 through the present.

        The Probate Proceeding was set for trial on January 15, 2016. Prior to trial, the attorney ad litem filed a Motion to Sever asking the Court to sever all matters related to the requested modification of the Trust and the sale of Trust assets, as plead for, in part, in the petition originally filed by the Trustees and in the attorney ad litem's Counterclaim, into a separate cause to proceed to trial. The attorney ad litem also filed a Motion for Continuance requesting that the Court continue the trial of all remaining matters, including the attorney ad litem's request for an accounting and the issues concerning the termination of the Trust, to a later date (the "Remaining Matters"). Prior to calling the case to trial, the Court granted the attorney ad litem's Motion to Sever and Motion for Continuance, severed the matters related to the modification of the Trust and the sale of Trust assets ("Severed Proceeding"), and continued the Remaining Matters to a later date. The Severed Proceeding has been assigned Cause No. C-1-PB-16-000096 and is styled In re: TEL Offshore Trust.

        The Severed Proceeding proceeded to trial before the Court on January 15, 2016. At trial, the Court entered a final judgment granting the Trustees' request that the Trust Agreement be modified to permit the Trustees to direct the Partnership to sell the remaining overriding royalty interest held by the Partnership as soon as reasonably possible and granting the ad litem's request to sell all of the Royalty, notwithstanding any requirements of the Trust Agreement to the contrary. Thereafter, the Court ordered that the Trustees direct the Partnership to sell all of the Royalty owned by the Partnership on or before May 1, 2016. On April 25, 2016, the Court approved an extension of the May 1, 2016 deadline to June 30, 2016.

        On August 17, 2016, the attorney ad litem filed a Second Amended Answer and First Amended Counterclaim seeking an accounting and asserting, among other causes of action, that the Trustees have breached their fiduciary duties to the beneficiaries of the Trust. The Remaining Matters were originally set for trial on November 7, 2016. Trustees filed a motion for continuance of the Remaining Matters and a hearing for such continuance occurred on September 14, 2016. At the hearing, the Court granted the Trustees' motion for continuance of the Remaining Matters and scheduled the trial for June 12, 2017. There can be no assurances as to the outcome of the Remaining Matters and whether the Court will grant the requested relief, and if such relief is granted, when such actions will be completed.
