TSAKOS ENERGY NAVIGATION LIMITED AND SUBSIDIARIES

CONDENSED NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

JUNE 30, 2015 AND 2014

(Expressed in thousands of U.S. Dollars, except for share and per share data, unless otherwise stated)

1. Basis of Presentation

The accompanying unaudited consolidated financial statements of Tsakos Energy Navigation Limited (the “Holding Company”) and subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 6-K and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation have been included. Operating results for the six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.

The consolidated balance sheet as of December 31, 2014 has been derived from the audited financial statements included in the Company’s annual report on Form 20-F filed with the Securities and Exchange Commission on April 8, 2015 (“Annual Report”), but does not include all of the footnotes required by generally accepted accounting principles for complete financial statements.

A discussion of the Company’s significant accounting policies can be found in Note 1 of the Company’s consolidated financial statements included in the Annual Report. There have been no material changes to these policies in the six-month period ended June 30, 2015.

New Accounting Pronouncements:

(a) Consolidation: In February 2015, the FASB issued Accounting Standards Update (“ASU”) No. 2015-02-Consolidation. The amendments in this ASU affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. Management believes that this standard will not have a material effect on the Company’s financial position.

(b) Debt Issuance costs: In April 2015, the FASB issued ASU No. 2015-03-Interest-Imputation of Interest, to simplify the presentation of debt issuance costs. The amendments in this ASU would require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. Management believes that this standard will not have a material effect on the Company’s financial position.

(c) Fair Value Measurement: In May 2015, the FASB issued ASU No. 2015-07-Fair Value Measurement, which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using net asset value per share of the investment. Management believes that this standard will not have a material effect on the Company’s financial position.

(d) Revenue from Contracts with customers: In May 2015, the FASB issued ASU No. 2015-14-Revenue from Contracts with Customers, which defers the effective date of ASU 2014-09. Management believes that this standard will not have a material effect on the Company’s financial position.

(a) Tsakos Energy Management Limited (the “Management Company”): The Holding Company has a Management Agreement (“Management Agreement”) with the Management Company, a Liberian corporation, to provide overall executive and commercial management of its affairs for a monthly fee. Per the Management Agreement of March 8, 2007, effective from January 1, 2008, there is a prorated adjustment if at the beginning of each year the Euro has appreciated by 10% or more against the U.S. Dollar since January 1, 2007. In addition, there is an increase each year by a percentage figure reflecting 12 month Euribor, if both parties agree. In the first six months of 2015 and 2014 monthly fees for operating vessels are $27.5, for vessels chartered out, $20.4 for vessels on a bare-boat basis, and $35.8 for the LNG carrier, of which $10.0 is paid to the Management Company and $25.8 to a third party manager. Monthly management fees for the DP2 shuttle tankers have been agreed to $35.0, per vessel. Since the expiry of the bareboat charter of the VLCC Millennium on July 30, 2013, management fees for this vessel are $27.5 per month, of which $13.7 are payable to a third party manager. Management fees for the suezmax Eurochampion 2004 are $27.5 per month, of which, $12.0 are paid to a third party manager. In addition to the Management fee, the Management Agreement provides for an incentive award to the Management Company, which is at the absolute discretion of the Holding Company’s Board of Directors. In the first six months of 2015 an award of $1,142 was granted to the Management Company and is included in General and Administrative expenses in the accompanying Consolidated Statement of Operations. No such award was granted in the first six months of 2014. In addition, a special award of $425 was paid to the Management Company in relation to capital raising offerings during the first six months of 2015 and $400 in the first six months of 2014. These awards have been included as a deduction of additional paid in capital in the accompanying Financial Statements.

The Holding Company and the Management Company have certain officers and directors in common. The President, who is also the Chief Executive Officer and a Director of the Holding Company, is also the sole stockholder of the Management Company. The Management Company may unilaterally terminate its Management Agreement with the Holding Company at any time upon one year’s notice. In addition, if even one director was elected to the Holding Company’s Board of Directors without having been recommended by the existing Board, the Management Company would have the right to terminate the Management Agreement on ten days’ notice, and the Holding Company would be obligated as at June 30, 2015 to pay the Management Company an amount of approximately $166,285 calculated in accordance with the terms of the Management Agreement. Under the terms of the Management Agreement between the Holding Company and the Management Company, the Holding Company may terminate the Management Agreement only under specific circumstances, without the prior approval of the Holding Company’s Board of Directors.

Estimated future management fees payable over the next ten years under the Management Agreement, exclusive of any incentive awards and based on existing vessels and known vessels scheduled for future delivery, as at June 30, 2015 are:

Less - current portion		(300,564	)		(228,492	)
Long-term portion		1,103,861			1,189,844

(a) Credit facilities

As at June 30, 2015, the Company had six open reducing revolving credit facilities, all of which are reduced in semi-annual installments, and two open facilities which have both a reducing revolving credit component and a term bank loan component, with balloon payments due at maturity between December 2015 and April 2019. At June 30, 2015 there is no available unused amount.

Interest is payable at a rate based on the London interbank offered rate (“LIBOR”) plus a spread. At June 30, 2015, the interest rates on these facilities ranged from 0.96% to 5.19%.

(b) Term bank loans

Term loan balances outstanding at June 30, 2015 amounted to $710,339. These bank loans are payable in U.S. Dollars in quarterly or semi-annual installments, with balloon payments due at maturity between October 2016 and February 2025. Interest rates on the outstanding loans as at June 30, 2015, are based on LIBOR plus a spread.

On April 22, 2015, the Company signed a new five-year term bank loan for $35,190 relating to the pre and post delivery financing of the first LR1 tanker under construction. The first drawdown of $7,038 was made on April 23, 2015 for the payment of the second installment to the ship building yard. The loan is repayable in ten consecutive semi-annual installments of $977.5, commencing six months after the delivery of the vessel, plus a balloon of $25,415 payable together with the last installment.

On April 22, 2015, the Company signed a new seven-year term bank loan for $35,190 relating to the pre and post delivery financing of the second LR1 tanker under construction. The first drawdown of $7,038 was made

11

on April 22, 2015 for the payment of the second installment to the ship building yard. The loan is repayable in fourteen consecutive semi-annual installments equal to 1/32^nd of the amount drawn under the loan, commencing six months after the delivery of the vessel, plus a balloon sufficient to repay the loan in full.

On May 25, 2015, the Company signed a new eight-year term bank loan for $73,500 relating to the pre and post delivery financing of one shuttle tanker under construction. The first drawdown of $9,800 was made on May 26, 2015 for the payment of the second installment to the ship building yard. The loan is repayable in sixteen consecutive semi-annual installments of $2,300, commencing six months after the delivery of the vessel, plus a balloon of $36,700 payable together with the last installment.

At June 30, 2015, interest rates on these term bank loans ranged from 1.77% to 4.03%.

The weighted-average interest rates on the above executed loans for the applicable periods were:

Three months ended June 30, 2015	2.26	%
Three months ended June 30, 2014	2.43	%
Six months ended June 30, 2015	2.24	%
Six months ended June 30, 2014	2.44	%

The above revolving credit facilities and term bank loans are secured by first priority mortgages on all vessels, by assignments of earnings and insurances of the respectively mortgaged vessels, and by corporate guarantees of the relevant vessel-owning subsidiaries.

The loan agreements include, among other covenants, covenants requiring the Company to obtain the lenders’ prior consent in order to incur or issue any financial indebtedness, additional borrowings, pay dividends in an amount more than 50% of cumulative net income (as defined in the related agreements), sell vessels and assets, and change the beneficial ownership or management of the vessels. Also, the covenants require the Company to maintain a minimum liquidity, not legally restricted, of $100,020 at June 30, 2015 and $79,563 at December 31, 2014, a minimum hull value in connection with the vessels’ outstanding loans and insurance coverage of the vessels against all customary risks. Three loan agreements require the Company to maintain throughout the security period, an aggregate credit balance in a deposit account of $3,250 and two other loan agreements a monthly pro rata transfer to a retention account of any principal due but unpaid.

As at June 30, 2015 and December 31, 2014, the Company and its wholly and majority owned subsidiaries were compliant with the financial covenants in its loan agreements, including the leverage ratio and the value-to-loan requirements and all other terms and covenants, except in the case of the value-to-loan requirements in one of its loan agreements with an outstanding balance of $30,400 as of June 30, 2015 ($31,700 as of December 31, 2014). The value-to-loan ratio will be satisfied with the repayment of the next two scheduled semi-annual installments, amounting to $1,300 each, on August 4, 2015 and February 4, 2016 respectively and therefore, no additional amount has been reclassified in the current liabilities at June 30, 2015.

The Company’s liquidity requirements relate primarily to servicing its debt, funding the equity portion of investments in vessels and funding expected capital expenditure on dry-dockings and working capital. As of June 30, 2015, the Company’s working capital (non-restricted net current assets), amounted to $25,901 ($49,817 deficit at December 31, 2014). The Company’s working capital has returned to a working surplus despite the two loan facilities which are reaching their maturity in December 2015 and June 2016 amounting $119,075 in total, and the loan balance of $52,195 relating to the pre-delivery financing of the LNG carrier Maria Energy, which is falling due in the first quarter of 2016, and the repayment of $23,194 on sale of Delphi and Triathlon which are held for sale at June 30, 2015 (Note 12 (d)). However, on April 22, 2015 the Company raised $81,798 in a public offering of its 8.75% Series D Cumulative Perpetual Preferred Shares, net of underwriter’s commission and other expenses. Net cash flow generated from operations is the Company’s main source of liquidity whereas other management alternatives to ensure service of the Company’s commitments include, but are not limited to, the issuance of additional equity and utilization of suitable opportunities for asset sales, etc. Management believes, such alternatives along with current available cash holdings and cash expected to be generated from the operation of vessels, will be sufficient to meet the Company’s liquidity and working capital needs for a reasonable period of time.

At June 30, 2015, the Company was committed to seven floating-to-fixed interest rate swaps with major financial institutions covering notional amounts aggregating to $296,331, maturing from March 2016 through March 2021 on which it pays fixed rates averaging 3.25% and receives floating rates based on the six-month LIBOR (Note 11).

At June 30, 2015, the Company held six of the seven interest rate swap agreements, designated and qualifying as cash flow hedges, in order to hedge its exposure to interest rate fluctuations associated with its debt covering notional amounts aggregating to $246,081. The fair value of such financial instruments as of June 30, 2015 and December 31, 2014 in aggregate amounted to $8,455 (negative) and $7,046 (negative), respectively. The net amount of cash flow hedge losses at June 30, 2015 that is estimated to be reclassified into earnings within the next twelve months is $3,909.

At June 30, 2015 and December 31, 2014, the Company held one interest rate swap, that did not meet hedge accounting criteria. As such, the changes in its fair values during the first half of 2015 and 2014 have been included in change in fair value of non-hedging financial instruments in the table above, and amounted to a gain of $1,241 and $1,413, respectively.

At June 30, 2015 and December 31, 2014, the Company had four and seven bunker swap agreements respectively, in order to hedge its exposure to bunker price fluctuations associated with the consumption of bunkers by its vessels. The fair value of these financial instruments as of June 30, 2015 and December 31, 2014 was $3,321 (negative) and $9,228 (negative), respectively.

The changes in their fair values during the first half of 2015 and 2014 amounting to $5,907 (positive) and $81 (negative) respectively have been included in change in fair value of non-hedging financial instruments in the table above as such agreements do not meet the hedging criteria.

At June 30, 2015 and December 31, 2014, the Company held three bunker put option agreements in order to reduce the losses of the bunker swap agreements previously entered into. The value of those put options at June 30, 2015 was $534 (positive) and at December 31, 2014 $2,443 (positive). The change in their fair value in the first half of 2015 was $1,909 (negative). In the first half of 2015 the Company entered into two call option agreements for the same reasons as for the put options. The premium paid for the call options was $314 which equals their fair market value at June 30, 2015.

10. Commitments and Contingencies

As at June 30, 2015, the Company had under construction nine aframax tankers, two LR1 product tankers, one shuttle tanker and one LNG carrier. The total contracted amount remaining to be paid for the thirteen vessels under construction, plus the extra costs agreed as at June 30, 2015 was $641,325. Scheduled remaining payments as at June 30, 2015 were $49,486 from July to December 2015, $377,701 in 2016, and $214,138 in 2017. At June 30, 2015, there is a prepaid amount of $1,650 under an old shipbuilding contract which was terminated in 2014, which will be used against the contract price of future new buildings currently being discussed between the Company and the shipyard.

In the ordinary course of the shipping business, various claims and losses may arise from disputes with charterers, agents and other suppliers relating to the operations of the Company’s vessels. Management believes that all such matters are either adequately covered by insurance or are not expected to have a material adverse effect on the Company’s results of operations or financial condition.

Charters-out

The future minimum revenues of vessels in operation at June 30, 2015, before reduction for brokerage commissions, expected to be recognized on non-cancelable time charters are as follows:

Period/Year	Amount
July to December 2015		86,204
2016		129,345
2017		150,602
2018		156,680
2019 to 2029		806,200
Minimum charter payments		1,329,031

These amounts do not assume any off-hire.

11. Financial Instruments

(a) Interest rate risk: The Company is subject to interest rate risk associated with changing interest rates with respect to its variable interest rate term loans and credit facilities as described in Notes 5 and 6.

(b) Concentration of credit risk: Financial Instruments that are subject to credit risks consist principally of cash, trade accounts receivable, investments, and derivatives. The Company places its temporary cash investments, consisting mostly of deposits, primarily with high credit qualified financial institutions. The Company performs periodic evaluations of the relative credit standing of those financial institutions that are considered in the Company’s investment strategy. The Company limits its credit risk with accounts receivable by performing ongoing credit evaluations of its customers’ financial condition and generally does not require collateral for its accounts receivable and does not have any agreements to mitigate credit risk. The Company limits the exposure of non-performance by counterparties to derivative instruments by diversifying among counterparties with high credit ratings, and performing periodic evaluations of the relative credit standing of the counterparties.

(c) Fair value: The carrying amounts reflected in the accompanying Consolidated Balance Sheet of cash and cash equivalents, restricted cash, trade receivables and accounts payable approximate their respective fair values due to the short maturity of these instruments. The fair value of long-term bank loans with variable interest rates approximate the recorded values, generally due to their variable interest rates. The present value of the future cash flows of the portion of one long-term bank loan with a fixed interest rate is estimated to be approximately $36,566 as compared to its carrying amount of $37,410. The Company performs relevant enquiries on a periodic basis to assess the recoverability of the long-term investment and estimates that the amount presented on the accompanying balance sheet approximates the amount that is expected to be received by the Company in the event of sale of that investment.

The fair values of the one long-term bank loan with a fixed interest rate, the interest rate swap agreements, and bunker swap agreements, put option agreements and call option agreements discussed in Note 6 above are determined through Level 2 of the fair value hierarchy as defined in FASB guidance for Fair Value Measurements and are derived principally from or corroborated by observable market data, interest rates, yield curves and other items that allow value to be determined.

16

The estimated fair values of the Company’s financial instruments, other than derivatives at June 30, 2015 and December 31, 2014, are as follows:

	Carrying Amount June 30, 2015			Fair Value June 30, 2015			Carrying Amount December 31, 2014			Fair Value December 31, 2014
Financial assets/(liabilities)
Cash and cash equivalents		278,927			278,927			202,107			202,107
Restricted cash		9,056			9,056			12,334			12,334
Investments		1,000			1,000			1,000			1,000
Debt		(1,404,425	)		(1,403,581	)		(1,418,336	)		(1,417,430	)

Voyage revenue earned during the three months ended June 30, 2015 totaled $154.0 million, compared to $112.4 million earned in the three months ended June 30, 2014, a 37% increase. The increase was mostly due to the buoyant market for crude tankers spurred by increased demand due to low oil prices and helped by the limited increase in global fleet capacity. The product carrier market also showed signs of continued recovery due to low oil prices providing refineries with increased margins, while new refineries came on line in the Middle East and India. The two suezmax crude carriers acquired in mid-2014 also generated further revenue, while profit-share arrangements on certain time-charters provided $8.2 million.

During the second quarter of 2015, the Company operated on average 50.0 vessels compared to 48.2 vessels in the second quarter of 2014. Total utilization (total days that the vessels were actually employed as a percentage of total days in the period that we owned or controlled the vessels) achieved by the fleet in the second quarter of 2015 was 97.7%, down slightly from the second quarter of 2014, due to increased lost days arising from the dry-dockings of the product carriers Apollon, Ajax and Aris (completed in the second quarter) while the previous second quarter lost days related only to the dry-docking of the panamax World Harmony and the beginning of the dry-docking of the handysize Didimon. Both second quarters saw days lost due to the repositioning voyages of various other vessels. Operating days on pure time-charter without profit share fell by 253 days or 14.1% between the two second quarters, and the amount of revenue earned on such charters decreased only by 1.7% especially due to the VLCC Millenium which more than doubled its daily rate since the prior year second quarter, contributing by an additional $3.1 million. The number of days utilized in profit-share arrangements increased slightly in the second quarter of 2015 to 824 days in the second quarter of 2015, compared to 818 days in the second quarter of 2014, while revenue earned in profit sharing arrangements increased by 64.2% due to the improvement of the market and the profit share earned. The number of days in the second quarter of 2015 that vessels were employed on spot, contract of affreightment and pool voyages increased to 2,080 from 1,678 in the second quarter of 2014, a 24.0% increase as the Company sought to take advantage of the robust freight market, while revenue earned on those types of employment

1

increased by 57.5% accordingly. This was due to the strong freight market for crude and product carriers in the second quarter with all categories of tankers not on time-charter showing increases over the equivalent quarter of 2014. The seasonal factors which usually affect the second quarter had only a modest impact on 2015 revenue.

During the six months ended June 30, 2015, voyage revenue increased to $302.9 million, an increase of $60.2 million, or 24.8%, compared to revenue achieved in the six months ended June 30, 2014. For the first six months of 2015, on average 50.0 vessels were operated compared to 48.1 in the first six months of 2014. Since the beginning of 2014 to June 30, 2015, the Company has taken delivery of the suezmax tankers Eurovision in June 2014 and Euro in July 2014. For the first six months of 2015, the utilization achieved was 98.5%, compared to 97.9% in the first six months of 2014. Apart from the lost days of the second quarter, the six month period of 2015 also includes lost days on the commencement of the dry-docking of Aris in the first quarter and repositioning voyages of certain other vessels.

The average daily revenue per vessel for the second quarter of 2015, after deducting voyage expenses (time charter equivalent or TCE, see definition below) was $26,720 per day compared to $17,163 per day for the previous year’s second quarter. Average daily TCE rate earned for the three and six month periods ended June 30, 2015 and 2014 were:

	Three months ended June 30,				Six months ended June 30,

Handysize		18,300		10,578		18,765		13,190

TCE is calculated by taking voyage revenue less voyage expenses divided by the number of operating days. As from the first quarter of 2015 TCE rate commissions are included in voyage expenses in order to be consistent and comparable to other reporting entities within the peer group of tanker companies. Prior year’s second quarter and first six-month data has been adjusted accordingly.

Time charter equivalent revenue and TCE rate are not measures of financial performance under U.S. GAAP and may not be comparable to similarly titled measures of other companies. However, TCE is a standard shipping industry performance measure used primarily to compare period-to-period changes in shipping performance despite changes in the mix of charter types (i.e. spot voyage charters, time charters and bareboat charters) under which the vessels may be employed between the periods. The following table reflects the calculation of our TCE rate for the period presented (amount in thousands of U.S. dollars, except for TCE rate, which is expressed in U.S. dollars, and available days):

	Three months ended June 30,						Six months ended June 30,

Voyage expenses

Voyage expenses include costs that are directly related to a voyage, such as port charges, agency fees, canal dues and bunker (fuel) costs. These voyage expenses are borne by the Company unless the vessel is on time-charter or operating in a pool, in which case they are borne by the charterer or by the pool operators. As from the first quarter of 2015 commissions on revenue are included in voyage expenses, in order to be consistent with and comparable to other reporting entities within the peer group of tanker companies. They are borne by the Company for all types of charter.

Voyage expenses for the three months ended June 30, 2015 and 2014:

	Voyage expenses							Average daily voyage expenses per relevant vessel
	2015		2014					2015		2014
	$ million		$ million		increase/ (decrease)			$		$		increase/ (decrease)

Total		69.8		77.8		(10.3	)%		18,672		24,488		(23.8	)%

The amount of voyage expenses is highly dependent on the voyage patterns followed and part of the change between quarters may usually be explained by changes in the total operating days the fleet operated on spot charter. Voyage expenses were $35.2 million during the quarter ended June 30, 2015, compared to $38.8 million during the prior year’s second quarter, a 9.1% decrease. The number of days that the vessels were employed on types of employment bearing voyage expenses (spot and contract of affreightment) in the second quarter of 2015 was 1,989 compared to 1,587 in the prior year’s second quarter, an increase of 25.3%. The decrease in bunkering expenses between the second quarter of 2015 and 2014 is mainly due to the decrease in average bunker prices paid by 40.3%, offset by an increase in the volume consumed by 22.9%. The volume of bunkers consumed has increased due to the higher number of vessels employed in spot voyages. Total port expenses paid during the second quarter of 2015 were approximately the same as in the second quarter of 2014. Average port expenses per vessel per day were 18.5% lower than in the second quarter of 2014, mainly because there was a 25% increase in days that vessels operated in the spot market. Voyage expenses were $69.8 million in the first six months of 2015, compared to $77.8 million in the first six months of 2014, a 10.3% decrease. For the six month periods, the days the vessels were operating in types of employment bearing voyage expenses increased to 3,738 days in the first six months of 2015 compared to 3,176 days in the prior year’s equivalent period, a 17.7% increase. The volume of the bunkers consumed was higher by 31.6% in the first half of 2015 than in the first half of 2014, offset by a decrease in the bunker prices paid between the corresponding six month periods by 41.0%. Port and other expenses increased slightly by 1.5% between the six month periods but decreased by 13.8% on a daily basis for the same reasons referred to above for the three month periods.

Commissions amounted to $5.9 million or 3.8% of voyage revenue during the second quarter of 2015 compared to $4.1 million or 3.6% of voyage revenue during the second quarter of 2014. For the six month period ended June 30, 2015, commissions amounted to $11.8 million or 3.9% of voyage revenue compared to $9.1 million or 3.7% of voyage revenue in the corresponding period of 2014. The overall increase between the respective six month periods was due to increased revenue, commission rates remaining at similar levels.

Vessel operating expenses include crew expenses, insurances, repairs and maintenance, spares, stores, lubricants, and other expenses such as quality and safety, tonnage tax, registration fees and communications costs. As from January 1, 2015 foreign currency gains or losses, previously shown as a separate line item in the statement of operations, are included in the operating expenses line item in order to be consistent with and comparable to other reporting entities within the peer group of tanker companies.

Vessel operating expenses are borne by the Company for all vessels of the fleet during the second quarters and first six-months of 2015 and 2014. Total operating costs were $37.1 million during the quarter ended June 30, 2015 as compared to $34.9 million during the second quarter of 2014, an increase of 6.4%. Part of the increase is explained by the increase in fleet available days by 3.8% due to the addition of the new suezmaxes Euro and Eurovision in mid-2014. As a percentage of voyage revenues, vessel operating expenses were 24.1% in the second quarter of 2015 and 31.1% in the second quarter of 2014. In the six month periods, operating expenses as a percentage of voyage revenues were 24.1% in the first six months of 2015 and 29.4% in the first six months of 2014. For both respective periods, the fall in percentage of operating expenses to revenue is reflective of the fact that the growth in revenues significantly surpassed any increase in operating expenses.

Average operating expenses per ship per day for those vessels in the fleet incurring operating expenses increased to $8,164 for the quarter ended June 30, 2015 from $7,969 in the second quarter of 2014, an increase of $195 per day, or 2.4%.

4

The increase in vessel daily operating expenses in the second quarter is partly due to higher repairs, maintenance and spares mainly because of increased expenditure on repairs and engine spare parts during dry-dockings, contributing $367 on average to daily operating expenses as two vessels were in dry-dock in the second quarter of 2015, while just one vessel performed dry-docking in the second quarter of 2014. However, most of these increases were offset by the impact of the weakening of the Euro against the US Dollar by 19.3% since the second quarter of 2014, which in particular positively affected crew costs as most of our officers are paid in Euro, daily average crew costs falling by $225. The addition of the two suezmaxes increased the average daily operating expenses per vessel as the operating expenses for such large vessels is proportionally greater than for smaller categories of tankers. Other operating expenses also increased by $66 daily compared to the second quarter of 2014, mostly due to higher vessel tonnage taxes.

For the six month periods, there was a decrease in average operating expenses per vessel to $8,080 from $8,207, a reduction of $127 daily, or 1.5%. For the six-month period of 2015, the appreciation of the US Dollar by 18.54% against the Euro since the first six months of 2014 again impacted crew and other costs in the first half-year of 2015, offset by increased expenditure on spares arising from dry-dockings and the impact of the two suezmaxes.

Depreciation and Amortization of deferred charges

As from January 1, 2015 depreciation and amortization of deferred dry-docking costs are combined in one line item in order to be consistent with and comparable to other reporting entities within the peer group of tanker companies. Prior year comparable figures have been amended accordingly. Depreciation and amortization charges totaled $27.2 million in the second quarter of 2015 compared to $25.3 million in the second quarter of 2014, a 7.3% increase. Depreciation amounted to $25.0 million in the second quarter of 2015 and $23.9 million in the second quarter of 2014, the increase being mainly due to the addition of the two suezmax tankers Euro and Eurovision in mid-2014. For the first six months of 2015, depreciation was $49.7 million compared to $47.5 million in the first six months of 2014, a 4.5% increase, primarily due to the addition of the two suezmax tankers mentioned above. Amortization of deferred dry-docking charges was $2.2 million during the second quarter of 2015, compared to $1.4 million during the second quarter of 2014. For the six month period ended June 30, 2015 and 2014, amortization of deferred charges was $3.6 million and $2.6 million, respectively. The increase in both the three and six month periods is partly due to the extra vessel dry-docked in the second quarter of 2015 compared to the equivalent quarter of 2014, but primarily due to the immediate write-off of $0.8 million of deferred charges relating to the product carrier Delphi which was accounted for as held for sale at June 30, 2015 and sold in mid-July 2015.

Impairment

In the first half of 2015, vessel values had improved over values determined in prior periods. Thirty-six of our vessels had carrying values in excess of market values. However, the Company’s impairment tests did not indicate that an impairment charge was required for any vessel of the fleet at June 30, 2015. No impairment charge was required as at December 31, 2014.

General and administrative expenses

As from January 1, 2015, Management fees, administrative expenses, and Management incentive award are combined in one line item in order to be consistent with and comparable to other reporting entities within the peer group of tanker companies.

Management fees totaled $4.2 million during the quarter ended June 30, 2015, compared to $4.0 million for the quarter ended June 30, 2014, a 3.8% increase. For the six months ended June 30, 2015, management fees were $8.4 million compared to $8.1 million in the first half of 2014, a 3.9% increase. In both periods the increase is due to the addition of the shuttle tankers Euro and Eurovision in mid-2014.

The Company pays to Tsakos Energy Management Ltd. fixed fees per vessel under a management agreement between the companies. The fee pays for services that cover both the management of the individual vessels and of the enterprise as a whole. According to the management agreement, there is a prorated adjustment if at the beginning of the year the Euro has appreciated by 10% or more against the U.S. Dollar since January 1, 2007, and an increase each year by a percentage figure reflecting 12 month Euribor, if both parties agree. There has been no increase in management fees payable to the management company in 2014 and 2015 to date.

In the first half of 2015, all the vessels in the fleet have been managed by TCM, apart from the LNG carrier Neo Energy, the VLCC Millennium and the suezmax Eurochampion 2004 which have been managed by third-party managers. Monthly

5

management fees for operating conventional vessels are $27,500 per month. The monthly fee relating to vessels chartered-in or chartered-out on a bare-boat basis or for vessels under construction is $20,400. Management fees for Neo Energy are $35,833, of which $10,000 are payable to the management company and $25,833 to the third-party manager. Management fees for the DP2 suezmax shuttle tankers are $35,000 per month. Management fees for Millennium are $27,500 per month, of which $13,667 are payable to a third-party manager. Management fees for Eurochampion 2004 are $27,500 per month, of which $12,000 are payable to a third party manager. Management fees paid relating to vessels under construction are capitalized as part of the vessels’ costs.

Administrative expenses consist primarily of professional fees, office supplies, investor relations, advertising costs, directors’ liability insurance, directors’ fees and travel-related expenses. Such expenses were $1.1 million and $0.9 million during the quarters ended June 30, 2015 and 2014, respectively, the increase being due to higher professional fees and directors and officers insurance premiums. For the six months ended June 30, 2015 and 2014, general and administrative expenses were $2.3 million in both six month periods.

Following the 2014 restoration of profitability, the Board of Directors decided to reward the management company with an award of $1.1 million based on various criteria included in a new management incentive award program, approved by the Board of Directors in May 2015, which is included in General and administrative expenses in the statement of operations for first quarter of 2015 and for the first six months of 2015. There was no incentive award based on profitability accounted for within the second quarter of 2015 or in the first half of 2014.

General and administrative expenses plus the management fees and any incentive award, represent the overhead of the Company. On a per vessel basis, the daily overhead was $1,165 for the second quarter of 2015, compared to $1,121 in the second quarter of 2014. The increase is due to increased management fees. For the respective six month periods, the daily overhead per vessel was $1,310 and $1,188 respectively as both management fees and administrative expenses increased, and there was the incentive award accounted for in the first quarter, 2015.

Operating income

Income from vessel operations was $49.2 million during the second quarter of 2015, compared to $8.5 million during the second quarter of 2014. During the first half of 2015, income from vessel operations was $94.9 million, compared to $33.0 million during the first half of 2014, representing an increase of 187.7%.

Interest and finance costs

Interest and finance cost analysis in the table below is not presented according to U.S. GAAP guidelines. However, management believes that this analysis may provide its users a better understanding of the Company’s finance cost. Management also uses this analysis in making financial and planning decisions.

Interest and finance costs were $7.9 million for the second quarter of 2015, compared to $8.6 million for the quarter ended June 30, 2014, a 7.4% reduction. Loan interest in the second quarter 2015 (excluding the impact of interest rate swaps) fell 13.2% to $7.2 million from $8.2 million in the second quarter of 2014. The average balance of outstanding debt was

6

approximately $1,409 million for the second quarter of 2015 compared to $1,341 million for the previous year’s second quarter. However, the average loan interest rate fell to 2.0% during the second quarter of 2015 from 2.4% in the second quarter of 2014, mainly due to the restoration of lower interest rate margins to levels in place prior to the imposition of higher margins during the period that covenant waivers were in place until June 30, 2014.

Interest paid on hedging and non-hedging interest rate swaps amounted to $1.6 million in the second quarter of 2015 compared to $1.5 million in the second quarter of 2014. As a result, the average all-in loan finance cost in the second quarter of 2015, taking account of net swap interest paid on hedging and non-hedging interest rate swaps, was 2.6% compared to 2.9% in the previous year’s second quarter.

For the six months ended June 30, 2015, interest and finance costs were $16.4 million compared to $18.1 million for the six months ended June 30, 2014, a 10.2% decrease. Loan interest decreased to $14.3 million in the six months ended June 30, 2015 from $16.6 million in the six months ended June 30, 2014 despite an increase of the average loan balances from $1,354 million to $1,409 million. Interest rates on loans averaged 2.0% in the six months to June 30, 2015, while in the first half-year of 2014 they averaged 2.4%, the fall being due to lower interest rates, as explained above. Interest paid on hedging and non-hedging swaps decreased to $2.1 million in the six months ended June 30, 2015 from $3.2 million in the prior year first six months due to the expiry of one interest rate swap since in the first quarter of 2014.

There was a non-cash positive net movement of $1.0 million in the fair value (mark-to-market) of the non-hedging interest rate swaps in the second quarter of 2015, compared to a positive movement of $0.7 million in the second quarter of 2014. In the six months ended June 30, 2015, there was a positive movement of $0.8 million compared to a positive movement of $1.4 million for the first six months of 2014.

There was a cash settlement of $1.6 million on non-hedging bunker swaps in the second quarter of 2015, offset by a positive change of $1.5 million on the fair market value of the same bunker swaps. Those swaps had insignificant cash receipts and movement in valuations in the second quarter of 2014. For the first six months of 2015, total cash paid on the bunker hedges totaled $4.6 million and positive movements on bunker swaps totaled $4.3 million, while in the first six months of 2014, there were insignificant movements in receipts and valuation movements.

Other finance costs include amortization of loan fees, which amounted to $0.3 million in both the first quarter of 2015 and the first quarter of 2014. For both the respective six-month periods, an amount of $0.6 million of loan expenses was amortized. In the second quarter of 2015 other finance costs include a charge of $0.4 million relating to finance project costs which were expensed as they would have to be repeated if the project to which they relate actually occurs. In the six-month period of 2015, such costs amounted to $1.3 million. There were no such costs in the first half of 2014.

Capitalized interest is based on expenditure incurred to date on vessels under construction. Capitalized interest was $0.7 million in both the second quarter of 2015 and 2014. For the first six months of 2015 and 2014, capitalized interest was $1.3 million and $1.2 million, respectively.

Interest income

Total income derived from bank deposits was $0.1 million during both the second quarter of 2015 and 2014. For the six month periods ended June 30, 2015 and 2014, $0.1 million and $0.1 million were earned respectively.

Net income attributable to the non-controlling interest

There is a non-controlling interest of 49% in the subsidiary Mare Success S.A., which owns 100% of each of the companies that own the panamax vessels Maya and Inca. Income attributable to the non-controlling interest in both the second quarters of 2015 and 2014 amounted to less than $0.1 million. Similarly, for the six months ended June 30, 2015 and 2014, the net loss attributable to the non-controlling interest was under $0.1 million in both periods.

Net income attributable to Tsakos Energy Navigation Limited

As a result of the foregoing, the net income attributable to Tsakos Energy Navigation Limited for the quarter ended June 30, 2015 was $41.3 million, or $0.45 earnings per share, taking into account cumulative preferred dividends of $3.4 million, versus net income of $0.2 million, or $0.02 loss per share, taking into account cumulative preferred dividends of $2.1 million for the quarter ended June 30, 2014. The net income attributable to Tsakos Energy Navigation Limited for the six months ended June 30, 2015 was $78.6 million, or $0.86 earnings per share, taking into account the effect of cumulative dividends of $5.5 million on our preferred stock, versus $14.8 million net income, or $0.14 earnings per share, taking into account the effect of cumulative preferred dividends of $4.2 million for the six months ended June 30, 2014.

Liquidity and capital resources

Liquidity requirements relate to servicing debt, funding the equity portion of investments in vessels, funding working capital and controlling fluctuations in cash flow. In addition, our new building commitments, other expected capital expenditure on dry-dockings and vessel acquisitions will require us to expend cash in 2015 and in future years. Net cash flow generated by operations is the main source of liquidity. Apart from the possibility of issuing further equity, additional sources of cash include proceeds from asset sales and borrowings, although all borrowing arrangements to date have specifically related to the acquisition of vessels.

We believe, given our current cash holdings and the number of vessels we have on time charter, that if market conditions remain relatively stable throughout 2015, our financial resources, including the cash expected to be generated within the year, will be sufficient to meet our liquidity and working capital needs through June 30, 2016, taking into account our existing capital commitments and debt service requirements. If market conditions worsen significantly, then our cash resources may decline to a level that may put at risk our ability to service timely our debt and capital expenditure commitments. In order to avoid such an eventuality, management would expect to be able to raise extra capital through the alternative sources described above.

Working capital (non-restricted net current assets) at June 30, 2015 amounted to $25.9 million positive, compared to a negative of $49.8 million at December 31, 2014. The difference includes primarily an increase in cash, and the inclusion of vessels held for sale in current assets, offset by the inclusion of the debt relating to vessels held for sale included in current liabilities. Non-restricted cash balances at June 30, 2015 were $278.9 million compared to $202.1 million at December 31, 2014.

Net cash provided by operating activities was $42.1 million in the quarter ended June 30, 2015, compared to $8.1 million in the previous year’s second quarter. For the six month respective periods, net cash from operating activities was $97.5 million in 2015, compared to $26.9 million in the first six months of 2014. The increase in both periods was due to the significant increase in revenue arising from the strong freight market as discussed further above.

The increase in the amount of receivables due from charterers in the quarter ended June 30, 2015 amounted to $20.7 million, which is due to the increase in revenue and effectively means that this amount of revenue was not collected within the period and therefore appears as a deduction from net income in the cash flow statement. This increase is also related to the increase in spot voyages, as when a vessel is employed on the spot voyage, freight is collected upon the completion of the voyage. In the previous year second quarter there was no increase in receivables.

Expenditure incurred for dry-dockings and special survey purposes, which are deferred and amortized to expense over the period from the dry-docking to the date of the next scheduled dry-docking, is deducted from net income to calculate cash generated by operating activities. In the second quarter of 2015, an amount of $2.0 million was paid on the dry-dockings of

8

Apollon and Ajax, while payments totaling $0.8 million was paid on the dry-docking of World Harmony in the second quarter of 2014. For the six month periods, $2.9 million was paid in 2015 compared to $2.2 million in the previous year’s first six months.

Net cash used in investing activities was $32.8 million for the quarter ended June 30, 2015, and $63.2 million for the quarter ended June 30, 2014. In the second quarter of 2015, $32.0 million was paid relating to the newbuilding program and a further $0.8 million for additions and improvements to existing vessels. In the second quarter of 2014, net funds for the acquisition of the suezmax Eurovision amounted to $61.5 million and $0.4 million were paid for additions and improvements to existing vessels. In total, additions to existing vessels and improvements amounted to $1.8 million in the first six months of 2015 and $0.8 million in the first six months of 2014.

There was one LNG carrier, nine aframaxes, one DP2 suezmax shuttle tanker and two LR1 product carriers under construction as at June 30, 2015. The total contracted amount plus the extra costs agreed for the thirteen vessels is $886.7 million and, until June 30, 2015, we had made progress payments of $245.3 million (including $127.5 million which was financed by bank loans). The scheduled remaining yard installments are $49.5 million in the remainder of 2015, of which $14.9 million in total were paid between July and September 8, 2015. Scheduled installments for 2016 are $377.7 million and for 2017 $214.2 million. Pre- and post- delivery financing has been arranged for the nine aframaxes, the two LR1 product carriers and the shuttle tanker. Up to June 30, 2015, $75.3 million have been drawn down and paid to the yards. The Company has also drawn down $52.2 million for the pre-delivery financing of the LNG carrier and is in discussions with banks for its post-delivery financing. The LNG carrier is expected to be delivered in the first quarter of 2016, the aframaxes are expected to be delivered at various dates between the second quarter of 2016 and the third quarter of 2017, the LR1 panamax tankers in the third quarter of 2016 and the suezmax DP2 shuttle tanker in the first quarter of 2017.

Net cash provided by financing activities was $69.8 million in the quarter ended June 30, 2015, compared to $88.5 million during the quarter ended June 30, 2014. Net cash provided by financing activities was $56.0 million in the six months ended June 30, 2015, compared to $151.4 million during the six months ended June 30, 2014. In the second quarter of 2015, $29.0 million of new debt was drawn down for the pre-delivery financing of one aframax tanker ($5.1 million), two LR1 product carriers ($14.1 million) and the shuttle tanker ($9.8 million) under construction, while in the second quarter of 2014, $42.0 million of new debt was drawn down for the acquisition of the suezmax tanker Eurovision. Payments of long term debt amounted to $33.9 million for both the second quarters of 2015 and 2014.

In the second quarter of 2015 the company completed an offering of 3,400,000 of its 8.75% Series D perpetual preferred shares, raising $81.8 million, net of underwriting commissions and related expenses.

Total debt outstanding decreased from $1,409 million at the beginning of the second quarter of 2015 to $1,404 million at the end of the quarter. The debt to capital (equity plus debt) ratio was 51.5% at June 30, 2015 (or 45.8% on a net of cash basis). No new interest rate swaps have been arranged in the second quarter of 2015. Interest rate swap coverage on outstanding loans, including fixed interest loan coverage, at June 30, 2015 was approximately 23.8%.

Quarterly dividends of $0.06 per common share were paid on February 19, 2015 and on May 28, 2015 amounting to $10.2 million in total. On May 22, 2015, the Company declared a $0.06 per common share dividend payable on September 10, 2015 to common shareholders of record on September 3, 2015. On July 31, 2015 the Company declared another dividend of $0.06 per common share payable on December 15, 2015 to common shareholders of record on December 9, 2015. The dividend policy of the Company is to pay dividends on a quarterly basis. The payment and the amount of dividends are subject to the discretion of our board of directors and depend, among other things, on available cash balances, anticipated cash needs, our results of operations, our financial condition, and any loan agreement restrictions binding us or our subsidiaries, as well as other relevant factors.

On January 30, 2015 and April 30, 2015 the Company paid dividends of $0.50 per share each or $2.0 million in total, on its 8.00% Series B Preferred Shares. On January 29, 2015 and April 29, 2015 the Company paid dividends of $0.5547 per share each or $2.2 million in total, on its 8.875% Series C Preferred Shares. During the six month period ended June 30, 2014, the Company paid two dividends of $0.50 per share each or $2.0 million in total, on its 8% Series B Preferred Shares and two dividends, the first of $0.73958 per share or $1.5 million in total and the second dividend of $0.55469 per share or $1.1 million in total, on its 8.875% Series C Preferred Shares.

On July 9, 2015 it was announced that the Board of Directors declared a regular quarterly dividend of $0.50 per share for the 8.00% Series B Cumulative Redeemable Perpetual Preferred Shares, which was paid on July 30, 2015. On the same date it was announced that the Board of Directors declared a quarterly dividend of $0.55469 per share for the 8.875% Series C Cumulative Redeemable Perpetual Preferred Shares, which was paid on July 30, 2015. Each dividend is for the period from April 30, 2014 through July 29, 2014.

9

On August 13, 2015, it was announced that the Board of Directors had declared the first dividend of $0.72309 per share on the Company’s 8.75% Series D Cumulative Redeemable Perpetual Preferred Shares, which was paid on August 28, 2015. Preferred share dividends on the Series D Preferred Shares are payable quarterly in arrears on the 28th day of February, May, August and November of each year, when, as and if declared by the Company’s board of directors.

The Company is currently in full compliance with all the original financial covenants contained within its loan agreements with the exception of one loan, where the value-to-loan ratio is not in compliance, with a minor shortfall. However, it is expected that this will be remediated with a scheduled repayment in February 2016, assuming a modest increase in the vessel valuation.

3.2 No Shares shall be issued until they are fully paid except as may be prescribed by a general meeting of the Company.

3.3 The holders of Common Shares shall, subject to these Bye-laws (including, without limitation, the rights attaching to Preferred Shares):

(a) be entitled to one vote per share;

(b) be entitled to such dividends as the Board may from time to time declare;

(d) generally be entitled to enjoy all of the rights attaching to shares.

3.4 The Board is authorised to provide for the issuance of the Preferred Shares in one or more series, and to establish from time to time the number of shares to be included in each such series, and to fix the terms, including designation, powers, preferences, rights, qualifications, limitations and restrictions of the shares of each such series (and, for the avoidance of doubt, such matters and the issuance of such Preferred Shares shall not be deemed to vary the rights attached to the Common Shares or, subject to the terms of any other series of Preferred Shares, to vary the rights attached to any other series of Preferred Shares). The authority of the Board with respect to each series shall include, but not be limited to, determination of the following:

(a) the number of shares constituting that series and the distinctive designation of that series;

¹  The share capital was increased from $40 million to $100 million by resolution passed on 25 May 2005 and to $200 million by resolution passed on 30 May 2014.

4

(b) the dividend rate on the shares of that series, whether dividends shall be cumulative and, if so, from which date or dates, and the relative rights of priority, if any, of the payment of dividends on shares of that series;

(c) whether the series shall have voting rights, in addition to the voting rights provided by law and, if so, the terms of such voting rights;

(e) whether or not the shares of that series shall be redeemable or repurchaseable and, if so, the terms and conditions of such redemption or repurchase, including the manner of selecting shares for redemption or repurchase if less than all shares are to be redeemed or repurchased, the date or dates upon or after which they shall be redeemable or repurchaseable, and the amount per share payable in case of redemption or repurchase, which amount may vary under different conditions and at different redemption or repurchase dates;

(f) whether that series shall have a sinking fund for the redemption or repurchase of shares of that series and, if so, the terms and amount of such sinking fund;

(g) the right of the shares of that series to the benefit of conditions and restrictions upon the creation of indebtedness of the Company or any subsidiary, upon the issue of any additional shares (including additional shares of such series or any other series) and upon the payment of dividends or the making of other distributions on, and the purchase, redemption or other acquisition by the Company or any subsidiary of any issued shares of the Company;

(h) the rights of the shares of that series in the event of voluntary or involuntary liquidation, dissolution or winding up of the Company, and the relative rights of priority, if any, of payment in respect of shares of that series; and

(i) any other relative participating, optional or other special rights, qualifications, limitations or restrictions of that series.

3.5 Any Preferred Shares of any series which have been redeemed (whether through the operation of a sinking fund or otherwise) or which, if convertible or exchangeable, have been converted into or exchanged for shares of any other class or classes shall have the status of authorised and unissued Preferred Shares of the same series and may be reissued as a part of the series of which they were originally a part or may be reclassified and reissued as part of a new series of Preferred Shares to be created by resolution or resolutions of the Board or as part of any other series of Preferred Shares, all subject to the conditions and the restrictions on issuance set forth in the resolution or resolutions adopted by the Board providing for the issue of any series of Preferred Shares.

3.6 At the discretion of the Board, whether or not in connection with the issuance and sale of any shares or other securities of the Company, the Company may issue securities, contracts, warrants or other instruments evidencing any shares, option rights, securities having

5

conversion or option rights, or obligations on such terms, conditions and other provisions as are fixed by the Board including, without limiting the generality of this authority, conditions that preclude or limit any person or persons owning or offering to acquire a specified number or percentage of the issued Common Shares, other shares, option rights, securities having conversion or option rights, or obligations of the Company or transferee of the person or persons from exercising, converting, transferring or receiving the shares, option rights, securities having conversion or option rights, or obligations.

3.7 All the rights attaching to a Treasury Share shall be suspended and shall not be exercised by the Company while it holds such Treasury Share and, except where required by the Act, all Treasury Shares shall be excluded from the calculation of any percentage or fraction of the share capital, or shares, of the Company.

3.8 Subject to these Bye-laws and to any resolution of the Shareholders to the contrary, and without prejudice to any special rights previously conferred on the holders of any existing shares or class of shares, the Board shall have the power to issue any unissued shares on such terms and conditions as it may determine and any shares or class of shares may be issued with such preferred, deferred or other special rights or such restrictions, whether in regard to dividend, voting, return of capital, or otherwise as the Company may by resolution of the Board prescribe.

3.9 Whenever the capital of the Company is divided into different classes of shares all or any of the special rights for the time being attached to any class of shares for the time being issued may (unless otherwise provided by the terms of issue of the shares of that class) be altered or abrogated either whilst the Company is a going concern or during or in contemplation of a winding up, with the consent in writing of the holders of not less than two-thirds of the issued shares of that class, or with the sanction of a Resolution passed at a separate general meeting of the holders of the issued shares of that class voting in person or by proxy. To every such separate general meeting, all the provisions of these Bye-Laws relating to general meetings of the Company or to proceedings thereat, shall, mutatis mutandis, apply, except that the necessary quorum shall be two persons at least holding or representing by proxy not less than a majority of the issued shares of that class (but so that if at any adjourned meeting of such holders a quorum as above defined is not present, those holders of shares of that class who are present shall be a quorum) and, that the holders of shares of the relevant class shall be entitled on a poll to one vote for every such share of the class held by them and that any holder of shares of the relevant class present in person or by proxy may demand a poll; Provided that if the Directors determine that any such alteration or abrogation is not materially adverse to the interests of the holders of the relevant class of shares, such variation shall not require the consent of the holders of such classes of shares. For such purposes the Directors may treat all the classes of shares as forming one class if they consider that all such classes would be affected in the same way by the proposals under consideration but in any other case shall treat them as separate classes.

3.10 The special rights conferred upon the holders of any shares or class of shares shall not, unless otherwise expressly provided in the rights attaching to or the terms of issue of such shares, be deemed to be altered by the creation or issue of further shares ranking pari passu therewith.

3.11 Subject to the provisions of the Companies Acts and to any rights conferred on the holders of any class of shares, the Company may, if the Board so determines, purchase shares of any class, including redeemable shares, in issue at the date of the passing of such Resolution. All such purchases shall be conditional upon no shareholders or persons resident for tax purposes in such jurisdiction as the Board may nominate from time to time owning or controlling 50 per cent or more of the issued share capital or the votes attaching to the issued and outstanding share capital of the Company following such purchase. Any share so purchased shall be treated as cancelled and the amount of the Company’s issued share capital shall be diminished by the nominal value of the shares purchased, but such purchase shall not be taken as reducing the amount of the Company’s authorised share capital.

6

3.12 The Company may adopt a scheme or arrangement (hereinafter called a “shareholder rights plan”) providing for the creation and issuance of rights entitling the Shareholders of the Company, or certain of them, to purchase from the Company shares of any class or assets of the Company or a subsidiary of the Company or otherwise, and the terms and conditions of such shareholder rights plan and rights may be approved, adopted, amended or modified either (i) as the Company may in general meeting determine or (ii) as the Directors or any committee thereof may determine, such shareholder rights plan to be attached as a Schedule to these Bye-Laws.

3.13 The Company may by notice in writing require any Shareholder whom the Directors know or suspect to be or at any time during the three years immediately preceding the date on which the notice is issued to have been interested in shares in the Company to give such information as may be required in accordance with Bye-law 3.15.

3.14 A notice under Bye-law 3.13 may require the person to whom it is addressed

(a) to give particulars of his own past or present interest in shares comprised in shares of the Company held by him at any time during the three year period mentioned in Bye-law 3.13;

(b) where the interest is a present interest and any other interest in the shares subsists or, in any case, where another interest in the shares subsisted during that three year period at any time when his own interest subsisted, to give (so far as lies within his knowledge), such particulars with respect to that other interest as may be required by the notice.

3.15 The particulars referred to in Bye-laws 3.14(a) and 3.14(b) include particulars of the identity of persons interested in the shares in question and of whether persons interested in the same shares are or were parties to any agreement or arrangement relating to the exercise of any rights conferred by the holding of the shares.

3.16 A notice under Bye-law 3.13 shall require any information given in response to the notice to be given in writing within such reasonable time as may be specified in the notice.

3.17 For the purposes of this Bye-law, a person is taken to be interested in any shares in which his or her spouse or reputed spouse or children and stepchildren aged under 18 are interested and a person is also taken to be interested in shares if

(a) a body corporate or limited partnership or partnership with separate legal personality of which he or she is a partner is interested in them;

(b) that body or its Directors (in the case of a body corporate) or general partner (in the case of a limited partnership) are accustomed to act in accordance with his directions or instructions; or

(c) he or she is entitled to exercise or control the exercise of one-fifth or more of the voting power of that body corporate or of any other body corporate which is entitled to exercise or control the exercise of any of the voting power in that body corporate.

3.18 Where in respect of any shares of the Company any holder fails to comply with any notice (in this Bye-law called a “Notice”) given by the Company under Bye-law 3.13 or where (in purported compliance with the Notice) such holder or other person makes a statement which is false or misleading in any material particular, then not earlier than 7 days after service of the Notice the Company may serve on such holder a notice (in this article called a “Disenfranchisement Notice”) stating that

(a) such shares shall with effect from the service of the Disenfranchisement Notice confer on him no right to vote either at any general meeting or at any separate general meeting of the holders of the shares of that class; and/or

(b) any dividends payable in respect of such shares may be withheld by the Company.

7

3.19 The Company may at any time withdraw a Disenfranchisement Notice by serving on the holder of the shares to which it relates a notice in writing to that effect. A Disenfranchisement Notice shall be deemed to have been withdrawn when the Notice has been complied with in respect of all the shares to which the Disenfranchisement Notice relates. Unless and until a Disenfranchisement Notice is deemed to have been withdrawn or the shares to which a Disenfranchisement Notice relates are registered in the name of some person other than the person in respect of whom the Disenfranchisement Notice was served, none of the shares to which a Disenfranchisement Notice relates shall (as the Disenfranchisement Notice may state) confer on the holder or holders thereof any right to attend or vote at such general meeting or separate general meeting as aforesaid nor entitle the holder or holders thereof to payment of any dividend otherwise payable on the same. The Directors may decline to register a transfer of such shares unless made upon acceptance of an offer for all the shares in the Company.

3.20 For the purposes of Bye-laws 3.13 to 3.20, a person shall be treated as appearing to be interested in any shares if the Shareholder holding such shares has given to the Company a notification in reply to a Notice which fails to establish the identities of those interested in the shares and if (after taking into account the said notification and any other relevant notifications) the Company knows or has reasonable cause to believe that the person in question is or may be interested in the shares.

3.21 The Company may issue its shares in fractional denominations and deal with such fractions to the same extent as its whole shares, and shares in fractional denominations shall have in proportion to the respective fractions represented thereby all of the rights of the whole shares including (but without limiting the generality of the foregoing) the right to vote, to receive dividends and distributions and to participate in a winding-up. The Company may redeem or repurchase any fractional denominations of shares, and may subdivide or combine any such fractional denominations of shares, pursuant to a resolution of the Board of Directors to the same extent as its whole shares and without any obligations to redeem or repurchase, or to subdivide or to combine, any whole shares in connection therewith.

4. OFFERING OF SHARES AND POWER TO PURCHASE

4.1 Subject to the provisions of these Bye-laws, the unissued shares of the Company (whether forming part of the original capital or any increased capital) shall be at the disposal of the Board, which may offer, allot, grant options over or otherwise dispose of them to such persons, at such times and for such consideration and upon such terms and conditions as the Board may determine.

4.2 The Company shall have the power to purchase its own shares for cancellation.

4.3 The Company shall have the power to acquire its own shares to be held as Treasury Shares.

4.4 The Board may exercise all of the powers of the Company to purchase or acquire its own shares, whether for cancellation or to be held as Treasury Shares in accordance with the Companies Act.

8

5. COMMISSIONS

The Board may exercise all powers of paying commissions or brokerage conferred or permitted by the Companies Acts and the commissions or brokerage may be satisfied by the payment of cash or by the allotment of fully or partly paid Shares or partly in one way and partly in the other.

6. SHARE CERTIFICATES

6.1 Except as ordered by a court of competent jurisdiction, as required by law or as otherwise provided in these Bye-laws, no person shall be recognised by the Company as holding any Share upon any trust, and the Company shall not be bound by or recognise any equitable, contingent or future interest in any Share or any fractional part of a Share, or any other right in respect of any Share, except an absolute right to such Share in the registered holder.

6.2 Unless specifically requested by a Shareholder in writing to the Company or the Registrar and Transfer Agent or so determined by the Directors, no certificates for Shares will be issued and the Shares will be issued in book entry form.

6.3 Every person whose name is entered as a Shareholder in the Register shall be entitled on payment of the sum (if any) required by Bye-law 6.6 to one certificate for all his Shares, or upon payment as aforesaid and of such reasonable out-of-pocket expenses as the Directors shall from time to time determine, to several certificates, each for one or more of his Shares. Where a Shareholder transfers part only of any holding of Shares represented by one certificate he shall be entitled to a balance certificate for the Shares retained by him. Every certificate shall be issued within two months after allotment or the lodgment with the Company of the transfer of the Shares, unless the conditions of issue of such Shares otherwise provide, and shall be under the Seal or facsimile thereof of the Company adopted by the Directors for that purpose and shall specify the number and class and distinguishing numbers (if any) and any requisite legends of the Shares to which it relates, and the amount paid up thereon. The Board may by resolution determine (either generally or in any particular case) that any signatures on any such certificate need not be autographic but may be affixed to such certificates by some mechanical means or may be printed thereon or that such certificates need not be signed by any person.

6.4 The Company shall not be bound to register more than four persons as the joint holders of any Share or Shares (except in the case of executors or trustees of a deceased Shareholder) and in the case of a Share held jointly by two or more persons, the Company shall not be bound to issue more than one certificate therefor, and delivery of a certificate for a Share to the first person whose name appears on the Register where there are joint holders in respect of any Shares shall be sufficient delivery to all.

6.5 If a Share certificate be worn out or defaced, then upon production thereof to the Directors, and on such reasonable indemnity as the Directors deem adequate being given, they shall order the same to be cancelled and shall issue a new certificate in lieu thereof. If any such certificate be lost or destroyed then, upon proof thereof to the satisfaction of the Directors, and on such reasonable indemnity as the Directors deem adequate being given, a new certificate in lieu thereof shall be issued.

6.6 For every certificate issued under Bye-law 6.3 there shall be paid to the Company the sum of US$1.00 or such smaller sum as the Directors may determine, provided that no such sum shall be payable if the request for such certificate is made on the application or registration form for subscription of the relevant Share.

6.7 Any Share issued by the Company and not registered under the Securities Act shall contain a legend in substantially the following form:

THIS SHARE HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933 (THE “SECURITIES ACT”). BY ITS ACCEPTANCE HEREOF, THE HOLDER HEREOF REPRESENTS THAT THIS SHARE IS BEING ACQUIRED FOR INVESTMENT, AND NOT WITH A VIEW TO, OR FOR SALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF AND AGREES FOR THE BENEFIT OF TSAKOS ENERGY NAVIGATION LIMITED (THE “COMPANY”) THAT THIS SHARE MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) TO THE COMPANY, (2) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER THAT IS AWARE THAT THE RESALE, PLEDGE OR OTHER TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, OR (3) PURSUANT TO ANOTHER EXEMPTION FROM REGISTRATION.

9

7. LIEN

7.1 The Company shall have a first and paramount lien on every Share (not being a fully paid up Share) for all monies, whether presently payable or not, called or payable, at a date fixed by or in accordance with the terms of issue of such Share, in respect of such Share. The Board may at any time either generally or in any particular case waive any lien that has arisen, or declare any Share to be wholly or in part exempt from the provisions of this Bye-Law. The Company’s lien on a Share shall extend to all dividends and other monies payable in respect of it.

7.2 The Company may sell, in such manner as the Board may think fit, any Share on which the Company has a lien, but no sale shall be made unless some sum in respect of which the lien exists is presently payable nor until the expiration of fourteen days after a notice in writing, stating and demanding payment of the sum presently payable and giving notice of the intention to sell in default of such payment, has been served on the holder for the time being of the Share.

7.3 The net proceeds of the sale by the Company of any Share on which it has a lien shall be applied in or towards payment or discharge of the debt or liability in respect of which the lien exists so far as the same is presently payable, and any residue shall (upon surrender to the Company for cancellation of the certificate for the Share sold and subject to a like lien for debts or liabilities not presently payable as existed upon the share prior to the sale) be payable to the holder immediately after such sale of the Share. For giving effect to any such sale the Board may authorise some person to transfer the Share sold to, or in accordance with the directions of, the purchaser thereof. The transferee shall be registered as the holder of the Share and he shall not be bound to see to the application of the purchase money, nor shall his title to the share be affected by any irregularity or invalidity in the proceedings relating to the sale.

8. CALLS ON SHARES

8.1 The Board may from time to time make calls upon the Shareholders in respect of any moneys unpaid on their shares (whether on account of the par value of the shares or by way of premium) and not by the terms of issue thereof made payable at a date fixed by or in accordance with such terms of issue, and each Shareholder shall (subject to the Company serving upon him at least fourteen days notice specifying the time or times and place of payment) pay to the Company at the time or times and place so specified the amount called on his shares. A call may be revoked or postponed as the Board may determine.

10

8.2 A call may be made payable by instalments and shall be deemed to have been made at the time when the resolution of the Board authorising the call was passed.

8.3 The joint holders of a share shall be jointly and severally liable to pay all calls in respect thereof.

8.4 If a sum called in respect of the share shall not be paid before or on the day appointed for payment thereof the person from whom the sum is due shall pay interest on the sum from the day appointed for the payment thereof to the time of actual payment at such rate as the Board may determine, but the Board shall be at liberty to waive payment of such interest wholly or in part.

8.5 Any sum which, by the terms of issue of a share, becomes payable on allotment or at any date fixed by or in accordance with such terms of issue, whether on account of the nominal amount of the share or by way of premium, shall for all the purposes of these Bye-laws be deemed to be a call duly made, notified and payable on the date on which, by the terms of issue, the same becomes payable and, in case of non-payment, all the relevant provisions of these Bye-laws as to payment of interest, forfeiture or otherwise shall apply as if such sum had become payable by virtue of a call duly made and notified.

8.6 The Board may on the issue of shares differentiate between the allottees or holders as to the amount of calls to be paid and the times of payment.

9. FORFEITURE OF SHARES

9.1 If a Shareholder fails to pay any call or instalment of a call on the day appointed for payment thereof, the Board may at any time thereafter during such time as any part of such call or instalment remains unpaid serve a notice on him requiring payment of so much of the call or instalment as is unpaid, together with any interest which may have accrued.

9.2 The notice shall name a further day (not being less than 14 days from the date of the notice) on or before which, and the place where, the payment required by the notice is to be made and shall state that, in the event of non-payment on or before the day and at the place appointed, the shares in respect of which such call is made or instalment is payable will be liable to be forfeited. The Board may accept the surrender of any share liable to be forfeited hereunder and, in such case, references in these Bye-laws to forfeiture shall include surrender.

9.3 If the requirements of any such notice as aforesaid are not complied with, any share in respect of which such notice has been given may at any time thereafter, before payment of all calls or instalments and interest due in respect thereof has been made, be forfeited by a resolution of the Board to that effect. Such forfeiture shall include all dividends declared in respect of the forfeited shares and not actually paid before the forfeiture.

9.4 When any share has been forfeited, notice of the forfeiture shall be served upon the person who was before forfeiture the holder of the share; but no forfeiture shall be in any manner invalidated by any omission or neglect to give such notice as aforesaid.

9.5 A forfeited share shall be deemed to be the property of the Company and may be sold, re-offered or otherwise disposed of either to the person who was, before forfeiture, the holder thereof or entitled thereto or to any other person upon such terms and in such manner as the Board shall think fit, and at any time before a sale, re-allotment or disposition the forfeiture may be cancelled on such terms as the Board may think fit.

9.6 A person whose shares have been forfeited shall thereupon cease to be a Shareholder in respect of the forfeited shares but shall, notwithstanding the forfeiture, remain liable to pay to the Company all moneys which at the date of forfeiture were presently payable by him to the

11

Company in respect of the shares with interest thereon at such rate as the Board may determine from the date of forfeiture until payment, and the Company may enforce payment without being under any obligation to make any allowance for the value of the shares forfeited.

9.7 An affidavit in writing that the deponent is a Director or the Secretary and that a share has been duly forfeited on the date stated in the affidavit shall be conclusive evidence of the facts therein stated as against all persons claiming to be entitled to the share. The Company may receive the consideration (if any) given for the share on the sale, re-allotment or disposition thereof and the Board may authorise some person to transfer the share to the person to whom the same is sold, re-allotted or disposed of, and he shall thereupon be registered as the holder of the share and shall not be bound to see to the application of the purchase money (if any) nor shall his title to the share be affected by any irregularity or invalidity in the proceedings relating to the forfeiture, sale, re-allotment or disposal of the share.

10. REGISTER OF SHAREHOLDERS

10.1 The Secretary or, as appropriate, the Registrar and Transfer Agent, shall enter or procure the entry in the Register of the particulars required by the Companies Acts, and the Register shall be kept in such manner as to show at all times the Shareholders of the Company for the time being and the Shares respectively held by them. The Register shall be open for inspection at the Registered Office or, as appropriate, the office of the Registrar and Transfer Agent, between ten o’clock in the forenoon (Bermuda time) and twelve o’clock noon (Bermuda time) on every Business Day. Unless the Board so determines, no Shareholder or intending Shareholder shall be entitled to have entered in the Register any indication of any trust or any equitable, contingent, future or partial interest in any share or any interest in any fractional part of a share and if any entry exists or is permitted by the Board it shall not be deemed to abrogate any of the provisions of Bye-law 6.1.

10.2 The Register may, after notice has been given by advertisement in an appointed newspaper and, where applicable, any other newspapers in accordance with the requirements of any Listing Exchange to that effect, be closed at such times or for such periods not exceeding in the whole thirty (30) days in each year as the Board may determine and either generally or in respect of any class of shares.

11. TRANSFER OF SHARES

11.1 Subject to the provisions of these Bye-Laws any Shareholder may transfer all or any of his Shares by an instrument in writing in such form as the Board may from time to time determine, which may be on the back of the Share certificate and need not be under seal.

11.2 The transferor shall be deemed to remain the holder of such Shares until the name of the transferee is entered in the Register in respect thereof. An instrument of transfer need not be signed by or on behalf of the transferee, save where the Shares are not fully paid.

11.3 Nothing in these Bye-Laws shall preclude the Directors from recognising a renunciation of the allotment of any Share by the allottee in favour of some other person.

11.4 The joint holders of a Share may transfer such Share to any one or more of such joint holders and the joint holders of two or more Shares may transfer such Shares, or any of them, to one or more of such joint holders, and the surviving holder or holders of any Share or Shares previously held by them jointly with a deceased Shareholder may transfer any such Shares to the executors or administrators of such deceased Shareholder.

11.5 No Share may be transferred or delivered directly or indirectly in the United States or to or for the account or benefit of a United States person (as defined within Regulation S under the

12

Securities Act), unless such Share has been registered under the Securities Act or such transaction is exempt from the registration requirements under the Securities Act and the Directors may decline to register any transfer of any Share or to deliver any Share until they have received such evidence as they may in their discretion require to satisfy them that such transaction is so exempt.

11.6 The Board may resolve, either generally or in any particular case upon request by either the transferor or transferee, to accept mechanically or electronically executed transfers and may also by resolution make such regulations with respect to such transfers in addition to or in substitution for the provisions of this Bye-Law as it considers appropriate. All instruments of transfer when registered may be retained by the Company, save where the Board refuses to register that transfer. If the Board refuses to register a transfer, the instrument of transfer shall (except in any case where fraud or any other issue involving dishonesty is suspected in relation to such transfer) be returned to the person who presented it. The Board may, in its absolute discretion, decline to register any transfer of any share which is not a fully-paid share.

11.7 The Board shall decline to register the transfer of any share to a person:-

(a) where the Board is of the opinion that such transfer might otherwise breach any law or requirement of any authority or any Listing Exchange until it has received such evidence as it may require to satisfy itself that no such breach would occur; or

(b) if the registration of which would be likely, in the opinion of the Board, to result in 50 per cent. or more of the aggregate issued share capital of the Company or shares of the Company to which are attached 50 per cent. or more of the votes attached to all outstanding shares of the Company being held or owned directly or indirectly by a person or persons resident for tax purposes in such jurisdiction as the Board may nominate from time to time.

11.8 For the purposes of this Bye-law, each Shareholder shall be deemed to be resident for tax purposes in the jurisdiction specified in the address shown in the Register for such Shareholder. If such Shareholder or person is not resident for tax purposes in such jurisdiction or if there is a subsequent change in his residence for tax purposes, such Shareholder shall notify the Company immediately of his residence for tax purposes.

11.9 Where any Shareholder fails to notify the Company in accordance with the foregoing, the Board may suspend sine die such Shareholder’s or person’s entitlement to vote or otherwise exercise any rights attaching to the Shares or interests therein and to receive payments of income which become due or payable in respect of such shares or interests and the Company shall have no liability to such Shareholder or person arising out of the late payment or non-payment of such sums and the Company may retain such sums for its own use and benefit. In addition to the foregoing the Board may dispose of the shares in the Company or interests therein of such Shareholder or person at the best price reasonably obtainable in all the circumstances. Where a notice informing such Shareholder or person of the proposed disposal of his shares or interests therein has been served, his shares or interests therein may not be transferred otherwise than in accordance with this Bye-law and any other purported transfer of such shares or interests therein shall not be registered in the books of the Company and shall be null and void.

11.10 The provisions of Bye-law 13.4 and the provisions of these Bye-laws relating to the protection of purchasers of shares sold under lien or upon forfeiture shall apply mutatis mutandis to a disposal of shares or interests therein by the Company or the Registrar in accordance with this Bye-law.

13

11.11 Without limiting the generality of the foregoing the Board may also decline to register any transfer unless:-

(a) such fee as the Board may from time to time approve and as is permitted by the Principal Stock Exchange is paid to the Company in respect thereof;

(b) the instrument of transfer is duly stamped and lodged with the Company, accompanied by the certificate for the shares to which it relates, if any, and such other evidence as the Board may reasonably require to show the right of the transferor to make the transfer;

(c) the instrument of transfer is in respect of only one class of shares; and

(d) where applicable, the permission of the Bermuda Monetary Authority with respect thereto has been obtained.

11.12 Subject to any directions of the Board from time to time in force the Secretary may exercise the powers and discretions of the Board under this Bye-law.

11.13 If 50 per cent. or more of the aggregate issued share capital of the Company or shares to which are attached 50 per cent. or more of the votes attached to all outstanding shares of the Company are found to be held or owned directly or indirectly by person or persons resident for tax purposes in such jurisdiction as the Board may nominate from time to time, the Board shall make an announcement to such effect and, if the Board so resolves, the Company shall either acquire (pursuant to Bye-law 4) or dispose of such shares of the Company held or owned by such persons as will result in the percentage of the aggregate issued share capital of the Company held or owned as aforesaid being less than 50 per cent. For these purposes the Company shall so acquire or dispose of such shares on the basis that the shares most recently acquired shall be the first to be disposed of (i.e. on the basis of last acquired first sold) save where there is a breach of the obligation to notify tax residency pursuant to the foregoing, in which event the shares of the person in breach thereof shall be so acquired or disposed of first. Shareholders shall not be entitled to raise any objection to the disposal of their shares, but the provisions of Bye-law 13.4 and the provisions of these Bye-laws relating to the protection of purchasers of shares sold under lien or upon forfeiture shall apply mutatis mutandis to any disposal of shares or interests therein made in accordance with this Bye-law.

11.14 If the Board declines to register a transfer it shall, within 60 days after the date on which the instrument of transfer was lodged, send to the transferor and the transferee notice of such refusal.

11.15 Notwithstanding anything contained in these Bye-laws, but subject to Bye-law 11.5, the Directors shall not decline to register any transfer of shares, nor may they suspend registration thereof where such transfer is executed by any bank or other person to whom such shares have been charged by way of security, or by any nominee or agent of such bank or person, and whether the transfer is effected for the purpose of perfecting any mortgage or charge of such shares or pursuant to the sale of such shares under such mortgage or charge, and a certificate signed by any officer of such bank or by such person that such shares were so mortgaged or charged and the transfer was so executed shall be conclusive evidence of such facts.

11.16 The Company may dispose of or transfer Treasury Shares for cash or other consideration

12. TRANSMISSION OF SHARES

12.1 In the case of death of a Shareholder, the survivor or survivors, where the deceased was a joint holder, and the estate representative of the deceased, where he was sole holder, shall be

14

the only person recognised by the Company as having any title to his interest in the Shares; but nothing herein contained shall release the estate of a deceased joint holder from any liability in respect of any Share jointly held by him. For the purpose of this Bye-Law, estate representative means the person to whom probate or letters of administration has or have been granted in Bermuda or, failing any further person, such other person as the Board may in its absolute discretion determine to be the person recognised by the Company for the purpose of this Bye-Law.

12.2 Any person becoming entitled to Shares in consequence of the death or bankruptcy of a Shareholder or otherwise by operation of law upon producing such evidence as the Directors may deem sufficient, may be registered as a Shareholder in respect of such Shares, or may, subject to Bye-Law 11 transfer such Shares to some other person by executing an instrument of transfer in a usual common form or any other form which the Directors may approve.

12.3 If the person so becoming entitled shall elect to be registered himself, he shall deliver or send to the Company a notice in writing signed by him stating that he so elects. If he shall elect to have another person registered, he shall testify his election by executing to such person a transfer of such Share. All the limitations, restrictions and provisions of these Bye-Laws relating to the right to transfer and the registration of transfers of Shares shall be applicable to any such transfer as aforesaid as if the death or bankruptcy of the Shareholder had not occurred and the transfer were a transfer executed by such Shareholder.

12.4 A person becoming entitled to a Share in consequence of the death, or bankruptcy of a Shareholder or otherwise by operation of law shall be entitled to receive and may give a discharge for all dividends and other monies payable on or in respect of the Share, but he shall not be entitled to receive notice of or to attend or vote at meetings of the Company, or, save as aforesaid, to any of the rights or privileges of a Shareholder until he shall have become a Shareholder in respect of the Share.

12.5 Subject to any directions of the Board from time to time in force, the Secretary may exercise the powers and discretions of the Board under this Bye-Law.

13. DISCLOSURE OF MATERIAL INTERESTS

13.1 Any person who acquires or disposes of an interest in shares such that the requirements of any applicable securities laws require a notification or filing to be made shall notify the Company immediately of such acquisition or disposal and the resulting interest of that person in shares.

13.2 If a person fails to give notification of a change in his interest in shares in accordance with Bye-law 13.1 and the Board believes that such person has acquired or disposed of an interest in shares in circumstances in which he would be subject to the notification requirements of Bye-law 13.1, the Board may serve upon that person a notice:-

(a) requiring him to comply with the notification requirements in relation to the change in his interest in shares; and

(b) informing him that, pending compliance with the notification requirements, the registered holder or holders of the shares in which that person is interested shall not be entitled to vote or otherwise exercise any rights attaching to the shares to which the notice relates nor shall such registered holder or holders be entitled to receive payments of income or capital which become due or payable in respect of such shares. The registered holder’s or holders’ entitlement to such payments shall be suspended pending compliance with the notification requirements without any liability of the Company to such holder or holders arising for late payment or non-payment and the Company may retain such sums for its own use and benefit during such period of suspension.

15

13.3 If the notice referred to in Bye-law 13.2 is not complied with within thirty days of the date of the service of such notice and the notice has not been withdrawn, the Company shall, so far as it is able either:

(a) acquire such shares itself pursuant to Bye-law 4 at the closing price of the Company’s shares on the date of acquisition; or

(b) dispose of the shares to which such notice relates at the best price reasonably obtainable in all the circumstances and it shall give written notice of such proposed disposal (the “Sale Notice”) to the person or persons on whom such notice was served.

Except as hereinafter provided, such an acquisition or disposal shall be completed as soon as reasonably practicable after the giving of the Sale Notice under this Bye-law and in any event within thirty days of the date of such notice. Where a Sale Notice has been served, the shares to which such notice refers may not be transferred otherwise than in accordance with this Bye-law and any purported transfer of such shares shall not be registered in the books of the Company and shall be null and void.

13.4 For the purpose of effecting an acquisition or disposal in accordance with Bye-law 13.3, the Board may authorise in writing any officer or employee of the Company to execute any necessary transfer on behalf of any Shareholder and may issue a new certificate to the purchaser. The net proceeds of any such disposal shall be received by the Company, whose receipt shall be a good discharge for the purchase money, and shall be paid (without any interest being payable thereon) to the former holder upon surrender by him of the certificate, if any, in respect of the shares sold and formerly held by him.

13.5 The provisions of these Bye-laws relating to the protection of purchasers of shares sold under a lien or upon forfeiture shall apply mutatis mutandis to disposals under this Bye-law.

14. INCREASE OF SHARE CAPITAL

The Company may from time to time increase its authorised share capital by such amount to be divided into Shares of such par value as the Company shall by Resolution, prescribe. The new Shares shall be subject to all the provisions of these Bye-Laws with reference to lien, the payment of calls, forfeiture, transfer, transmission and otherwise. The Company may, by the Resolution increasing the capital, direct that the new shares or any of them shall be offered in the first instance either at par or at a premium (or subject to the provisions of the Companies Acts) at a discount to all the holders for the time being of shares of any class or classes in proportion to the number of such shares held by them respectively or make any other provisions as to the issue of the new shares.

15. ALTERATION OF SHARE CAPITAL

15.1 The Company may from time to time by Resolution:-

(a) divide its Shares into several classes and attach thereto respectively any preferential, deferred, qualified or special rights, privileges or conditions;

(b) consolidate and divide all or any of its share capital into Shares of larger par value than its existing Shares;

(c) sub-divide its Shares or any of them into Shares of smaller par value than is fixed by its Memorandum, so, however, that in the sub-division the proportion between the amount paid and the amount, if any, unpaid on each reduced Share shall be the same as it was in the case of the Share from which the reduced Share is derived;

16

(d) make provision for the issue and allotment of Shares which do not carry any voting rights;

(e) cancel Shares which, at the date of the passing of the Resolution in that regard, have not been taken or agreed to be taken by any person, and diminish the amount of its Share capital by the amount of the Shares so cancelled; and

(f) change the currency denomination of its share capital.

Where any difficulty arises in regard to any division, consolidation or sub-division under this Bye-Law, the Board may settle the same as it thinks expedient and, in particular, may arrange for the sale of the Shares representing fractions and the distribution of the net proceeds of sale in due proportion amongst the Shareholders who would have been entitled to the fractions, and for this purpose, the Board may authorise some person to transfer the Shares representing fractions to the purchaser thereof, who shall not be bound to see to the application of the purchase money nor shall his title to the Shares be affected by any irregularity or invalidity in the proceedings relating to the sale.

Where, on any alteration or reduction of share capital, fractions of shares or some other difficulty would arise, the Board may deal with or resolve the same in such manner as it thinks fit.

15.2 Subject to the Companies Acts and to any confirmation or consent required by law or these Bye-Laws, the Company may by Resolution from time to time convert any Preferred Shares into redeemable Preferred Shares.

16. REDUCTION OF CAPITAL

16.1 Subject to the Companies Acts, its Memorandum and any confirmation or consent required by law or these Bye-Laws, the Company may from time to time by Resolution authorise the reduction of its issued share capital or any capital redemption reserve fund or any share premium or contributed surplus account, Provided that the share capital of the Company after such reduction is not less than the minimum share capital prescribed by the Memorandum.

16.2 In relation to any such reduction, the Company may by Resolution determine the terms upon which such reduction is to be effected including in the case of a reduction of part only of a class of Shares, those Shares to be affected.

17. GENERAL MEETING

17.1 The Board shall convene and the Company shall hold general meetings as Annual General Meetings in accordance with the requirements of the Companies Acts at such times and places as the Board shall appoint. The Board may, whenever it thinks fit, and shall, when required by the Companies Acts, convene general meetings other than Annual General Meetings which shall be called Special General Meetings.

17.2 The Board shall, on the requisition of Members holding at the date of the deposit of the requisition not less than one-tenth of such of the paid-up share capital of the Company as at the date of the deposit carries the right to vote at general meetings, forthwith proceed to convene a special general meeting and the provisions of the Act shall apply.

17.3 Any Shareholder may, by written notice served on the Board or the Secretary, require that a statement (not exceeding a reasonable length) be included in a notice of a general meeting regarding any matter concerning the governance, affairs or activities of the Company and that such matter be brought to the attention of the Shareholders at such general meeting Provided Always that the Board may refuse to include any statement which it reasonably considers to be defamatory or frivolous.

18. NOTICE OF GENERAL MEETINGS

18.1 An Annual General Meeting and any Special General Meeting shall be called by notice in writing not less than ten (10) nor more than fifty (50) days before the date of the meeting. Notwithstanding that a general meeting of the Company is called by shorter notice than that specified in this Bye-Law, it shall be deemed to have been duly called if it is so agreed:-

(a) in the case of a meeting called as an Annual General Meeting, by all Shareholders entitled to attend and vote thereat; and

If a quorum does not assemble within half an hour after the time appointed for the meeting, the meeting, if convened on the requisition of or by Shareholders shall be dissolved.

19

20.2 Subject to the provisions of Bye-law 20.3, any question proposed for the consideration of the Shareholders at any general meeting shall be decided on a show of hands or by a count of votes received in the form of electronic records and a declaration by the Chairman of the meeting that a question proposed for consideration has, on a show of hands or by a count of votes received in the form of electronic records, been carried or carried unanimously or by a particular majority not carried by a particular majority or lost shall be final and conclusive, and an entry to that effect in the Minute Book of the Company shall, subject to the provisions of Bye-law 20.3, be conclusive evidence of the fact without proof of the number or proportion of the votes recorded in favour of or against such question.

20.3 Notwithstanding the provisions of Bye-laws 20.2, at any general meeting of the Company it shall be lawful, in respect of any question proposed for the consideration of the Shareholders (whether before or on the declaration of the result of a show of hands or by a count of votes received in the form of electronic records as provided for in Bye-law 20.2 or on the withdrawal of any other demand for a poll) for a poll to be demanded by any of the following persons:-

(a) the Chairman of such meeting; or

(b) at least three Shareholders present in person or by proxy and entitled to vote; or

(c) any Shareholder or Shareholders present in person or by proxy and representing in the aggregate not less than one-tenth of the total voting rights of all the Shareholders having the right to vote at such meeting; or

(d) any Shareholder or Shareholders present in person or represented by proxy holding shares conferring the right to vote at such meeting, being shares on which an aggregate sum has been paid up equal to not less than one-tenth of the total sum paid on all such shares conferring such right.

The appointment of a proxy to vote at such a meeting shall be deemed to confer authority to demand or join in demanding a poll and, for the purpose of this Bye-Law, a demand by a Shareholder as proxy for another Shareholder shall be treated as distinct from any demand made in his own right.

20.4 At the conclusion of a poll demanded in accordance with the provisions of Bye-law 20.3 the voting papers or the electronic records shall be examined, and the result of the poll shall be declared, by the Chairman of the meeting and shall be deemed to be the resolution of the meeting at which the poll was demanded and shall replace any previous resolution upon the same matter which has been the subject of a show of hands.

A poll demanded on any other question shall be taken at such time (being not later than three months after the date of the demand) and place as the Chairman of the meeting shall direct. It shall not be necessary (unless the Chairman of the meeting otherwise directs) for notice to be given of a poll.

20.7 The demand for a poll shall not prevent the continuance of a meeting for the transaction of any business other than the question on which the poll has been demanded and it may be withdrawn at any time before the close of the meeting or the taking of the poll, whichever is the earlier.

20

20.8 A Shareholder who is a patient for any purpose of any statute or applicable law relating to mental health or in respect of whom an order has been made by any Court having jurisdiction for the protection or management of the affairs of persons incapable of managing their own affairs may vote, whether on a show of hands or on a poll, by his receiver, committee, curator bonis or other person in the nature of a receiver, committee or curator bonis and such committee, receiver, curator bonis or other person may on a poll vote by proxy, and may otherwise act and be treated as such Shareholder for the purpose of general meetings, provided that such evidence as the Directors may require of the authority of the person claiming to vote shall have been deposited at the office of the Company, which may be in the form of an electronic record, not less than thirty-six hours before the time for holding the meeting or adjourned meeting at which such person claims to vote.

20.9 If:

(a) any objection shall be raised to the qualification of any voter; or

(b) any votes have been counted which ought not to have been counted; or

(c) any votes are not counted which ought to have been counted,

the objection or error shall not vitiate the decision of the meeting or adjourned meeting on any resolution unless the same is raised or pointed out at the general meeting or, as the case may be, the adjourned meeting at which the vote objected to is given or tendered or at which the error occurs. Any objection or error shall be referred to the Chairman of the meeting and shall only vitiate the decision of the meeting on any question if the Chairman of the meeting decides that the same may have affected the decision of the meeting. The decision of the Chairman of the meeting on such matters shall be final and conclusive.

20.10 Except in the case of the removal of auditors and Directors and subject to these Bye-laws, anything which may be done by resolution of the Company in general meeting or by resolution of a meeting of any class of the Shareholders of the Company may, without a meeting, be done by resolution in writing, signed by a simple majority of all of the Shareholders (or such greater majority as is required by the Companies Acts or these Bye-laws) or their proxies, or in the case of a Shareholder that is a corporation (whether or not a company within the meaning of the Companies Acts) on behalf of such Shareholder, being a simple majority of all of the Shareholders of the Company who at the date of the resolution in writing would be entitled to attend a meeting and vote on the resolution. Such resolution in writing may be signed by, or in the case of a Shareholder that is a corporation (whether or not a company within the meaning of the Companies Acts), on behalf of, all the Shareholders of the Company, or any class thereof, in as many counterparts as may be necessary.

20.11 Notice of any resolution to be made under Bye-law shall be given, and a copy of the resolution shall be circulated to all Shareholders who would be entitled to attend a meeting and vote on the resolution in the same manner as that required for a notice of a meeting of Shareholders at which the resolution could have been considered, except that any requirement in this Act or in these Bye-laws as to the length of the period of notice shall not apply.

20.12 A resolution in writing is passed when it is signed by, or in the case of a Shareholder that is a corporation (whether or not a company within the meaning of the Companies Acts) on behalf of such number of the Shareholders of the Company who at the date of the notice represent a majority of votes as would be required if the resolution had been voted on at a meeting of Shareholders.

20.13 A resolution in writing made in accordance with Bye-law 20.10 is as valid as if it had been passed by the Company in general meeting or, if applicable, by a meeting of the relevant class of Shareholders of the Company, as the case may be. A resolution in writing made in accordance with Bye-law 20 shall constitute minutes for the purpose of the Companies Acts and these Bye-laws.

21

20.14 Members may participate in any general meeting by such telephonic, electronic or other communication facilities or means as permit all persons participating in the meeting to communicate with each other simultaneously and instantaneously, and participation in such a meeting shall constitute presence in person at such meeting.

20.15 The Board may, and at any general meeting, the Chairman of such meeting may, make any arrangement and impose any requirement or restriction it or he considers appropriate to ensure the security of a general meeting including, without limitation, requirements for evidence of identity to be produced by those attending the meeting, the searching of their personal property and the restriction of items that may be taken into the meeting place. The Board and, at any general meeting, the Chairman of such meeting are entitled to refuse entry to a person who refuses to comply with any such arrangements, requirements or restrictions.

21. JOINT HOLDERS OF SHARES

21.1 If two or more persons are registered as joint holders of any Share then any one of such persons may exercise such voting rights as may attach to such Share, either personally or by proxy, as if he were solely entitled thereto; and if more than one of such joint holders be present at any general meeting, personally or by proxy, then the vote of the senior shall be accepted to the exclusion of the votes of the other joint holders, and for this purpose seniority shall be determined by the order in which the names stand in the Register in respect of the joint holding; and

21.2 Any one of such joint holders may give effectual receipts for dividends, bonuses or other monies payable in respect of the Shares held by them as joint holders.

22. CORPORATE REPRESENTATIVES AND PROXIES

22.1 Where any company is a Shareholder any of its officers or any other person duly authorised by a resolution of its directors or other governing body, may act as its representative at any meeting of the Company. A person so authorised shall be entitled at any meeting of the Company to exercise on behalf of the company which he represents the same powers as that company could exercise if it were an individual Shareholder.

22.2 Any Shareholder entitled to attend and vote at a meeting of the Company shall be entitled to appoint another person as his proxy to attend and vote instead of him. A Shareholder may appoint a proxy in respect of part only of his holding of Shares. Proxies appointed by a single Shareholder need not exercise their votes in the same manner.

22.3 The instrument appointing a proxy shall be in writing under the hand of the appointor or of his attorney or such telephonic, electronic or other means as may be approved by the Board from time to time. The instrument appointing a proxy shall be in a form approved by the Board or in such other form as the Board may from time to time determine.

22.4 Unless the Company by Resolution so determines or required by the Companies Acts, a proxy need not hold any shares in the Company.

22.5 Subject to Bye-law 22.6, the appointment of a proxy must be received by the Company at the registered office or such other place or in such other manner as is specified in the notice convening the meeting or in any instrument or proxy sent out by the Company in relation to the meeting at which the person named in the appointment proposes to vote, and appointment of a proxy which is not received in the manner so permitted shall be invalid.

22

22.6 Any Shareholder may appoint a standing proxy or (if a corporation) representative by depositing at the Registered Office or such other place or in such manner as may be specified by the Company from time to time a proxy which may be in the form of an electronic record or (if a corporation) an authorisation and such proxy or authorisation shall be valid for all general meetings and adjournments thereof until notice of revocation is received at the Registered Office. Where a standing proxy or authorisation exists, its operation shall be deemed to have been suspended at any general meetings or adjournments thereof at which the Shareholder is present or in respect to which the Shareholder has specially appointed a proxy or representative. The Board may from time to time require such evidence as it shall deem necessary as to the due execution and continuing validity of any such standing proxy or authorisation and the operation of any such standing proxy or authorisation shall be deemed to be suspended until such time as the Board determines that it has received the requested evidence or other evidence satisfactory to it.

22.7 A vote given in accordance with the terms of an instrument of proxy shall be valid notwithstanding the previous death or insanity of the principal, or revocation of the instrument of proxy or the authority under which it was executed, provided that no intimation in writing of such death, insanity or revocation shall have been received by the Company at its registered office which may be in the form of an electronic record (or such other place as may be specified for the delivery of instruments of proxy in the notice convening the meeting or other documents sent therewith) one hour at least before the commencement of the meeting or adjourned meeting, or the taking of the poll, at which the instrument of proxy is used, or, where the appointment of the proxy was contained in an electronic communication, at the Address at which such appointment was duly received before the commencement of the meeting or adjourned meeting at which the proxy is to be used.

22.8 Subject to the Companies Acts, the Board may at its discretion waive any of the provisions of these Bye-Laws related to proxies or authorisations and, in particular, may accept such verbal or other assurances as it thinks fit as to the right of any person to attend and vote on behalf of any Shareholder at general meetings.

23. DIRECTORS

23.1 Subject to the following provisions of this Bye-Law 23, the Directors shall be chosen or elected at the Annual General Meeting of the Shareholders, and notice of such meeting shall specify that the election of the Directors will take place thereat. At every Annual General Meeting one-third of the Directors who are subject to retirement by rotation or, if their number is not three or a multiple of three, the number nearest to one-third shall retire from office; but, if there is only one Director who is subject to retirement by rotation, he shall retire.

23.2 Subject to the provisions of the Companies Acts and these Bye-laws, the Directors to retire by rotation shall be those who have been longest in office since their last appointment or reappointment, but as between persons who became or were last reappointed Directors on the same day those to retire shall (unless they otherwise agree among themselves) be determined by lot or by such other method as the Board may determine. The Directors to retire on each occasion (both as to number and identity) shall be determined by the composition of the Board at the date of the notice convening the Annual General Meeting and no Director shall be required to retire or be relieved from retiring or be retired by reason of any change in the number or identity of the Directors after the date of the notice but before the close of the meeting.

23

23.3 If the Company, at the meeting at which a Director retires by rotation or otherwise, does not fill the vacancy, the retiring Director shall, if willing to act, be deemed to have been reappointed unless at the meeting it is resolved not to fill the vacancy or unless a resolution for the reappointment of the Director is put to the meeting and lost.

23.4 Directors may be removed for cause by vote of the Shareholders or by resolution of the Directors. In this Bye-law, “cause” means wilful neglect, wilful default, fraud or dishonesty. Directors may be removed without cause by vote of the Shareholders. Notwithstanding the preceding sentences, a Director may not be removed at a special general meeting unless notice of any such meeting shall have been served upon the Director concerned not less than fourteen (14) days before the meeting and he shall be entitled to be heard at that meeting and provided further that the Resolution removing any Director is duly adopted by a majority of eighty per cent (80%) of those present and voting at a meeting. Subject to Bye-law 23.9, any vacancy created by the removal of a Director at a Special General Meeting may be filled at the Meeting by the election of another Director in his place or, in the absence of any such election, by the Board.

23.5 No person other than a Director retiring by rotation shall be appointed a Director at any general meeting unless he is recommended by the Board or he is nominated in accordance with the procedures set out in the Companies Acts and as provided by applicable US securities laws.

23.6 The Company shall at the Annual General Meeting and, subject to Bye-law 23.9, may by Resolution determine the minimum and the maximum number of Directors which shall be at least five (5) persons and not more than fifteen (15) persons (disregarding Alternate Directors).

23.7 Without prejudice to the power of the Company by Resolution in pursuance of any of the provisions of these Bye-laws to appoint any person to be a Director, the Board, so long as a quorum of Directors remains in office, shall have power at any time and from time to time to appoint any individual to be a Director so as to fill any vacancy occurring on the Board. The Board shall also have power to appoint additional Directors from time to time.

23.8 Some Directors may be appointed as Managing Directors and any Director so appointed shall not be subject to retirement by rotation but shall hold office for such period as may be determined by the Board pursuant to Bye-law 31.2.

23.9 A majority of the Directors must always be Directors (“Independent Directors”) who are independent as defined by the criteria of the Principal Exchange. If there is at any time not a majority of Independent Directors, as provided for in these Bye-Laws, the Board shall appoint as many replacement persons as are necessary as Independent Directors so that there is at all times a majority of Independent Directors.

23.10 No person shall be eligible for the office of Director at any General Meeting if:-

(a) he is less than twenty-one years of age;

(b) he is of unsound mind and has been so found by a Court in Bermuda or elsewhere;

(c) he is not an individual; or

(d) he has the status of bankrupt;

and unless within the prescribed time before the day appointed for the meeting, there shall have been given to the Secretary notice in writing by a Shareholder duly qualified to be present and vote at the meeting for which such notice is given, of his intention to propose such person for election and also notice in writing, signed by the person to be proposed, of his willingness to be elected.

23.11 No shareholding qualification for Directors shall be required.

24

24. VACATION OF OFFICE

24.1 The office of a Director shall be vacated upon the happening of any of the following events, namely:-

(a) if (not being a Managing Director holding office as such for a fixed term) he resigns his office by notice in writing under his hand sent to or left at the Registered Office or tendered at a meeting of the Board;

(b) if he becomes bankrupt or makes any arrangement or composition with his creditors generally;

(c) if he becomes of unsound mind or a patient for any purpose of any statute or applicable law relating to mental health and the Board resolves that his office is vacated;

(d) if he dies; or

(e) if he ceases to be a Director by virtue of the Companies Acts or is removed from office pursuant to these Bye-Laws.

24.2 Any such vacation of office as aforesaid shall be without prejudice to any claim for damages that such Director may have against the Company or the Company may have against such Director for any breach of any contract of service between him and the Company that may be involved in such vacation of office.

24.3 In the event that any of the Managing Directors who is also a Vice-President ceases to be a Director and is not otherwise replaced by a Managing Director who is a Vice-President, the remaining Managing Director(s) who is or are also Vice-President(s) (if any), subject to approval by the Directors, such approval not to be unreasonably withheld, may appoint replacement persons as Directors who will become Managing Director(s) and Vice-President(s) provided that the person so appointed shall not be a person whose election at the preceding Annual General Meeting was not carried.

24.4 If all the Managing Directors who are Vice-Presidents should cease to be Directors, the Directors may appoint replacement persons as Directors who will become additional Managing Directors and Vice-Presidents.

25. ALTERNATE DIRECTORS

25.1 The Company may in general meeting elect a person or persons qualified to be Directors to act as Directors in the alternative to any of the Directors of the Company, herein designated as “Alternate Directors” or may authorise the Board to appoint such Alternate Directors. Any Alternate Director may be removed by the Company in General Meeting and, if appointed by the Board may be removed by the Board and, subject thereto, the office of Alternate Director shall continue until the next annual election of Directors or if earlier, the date on which the relevant Director ceases to be a Director. An Alternate Director may also be a Director in his own right and may act as alternate to more than one Director.

25.2 An Alternate Director shall be entitled to receive notices of all meetings of the Directors, to attend, be counted in the quorum and vote at any such meeting at which any Director to whom he is alternate is not personally present, and generally to perform all the functions of any Director to whom he is alternate in his absence.

25.3 Every person acting as an Alternate Director shall (except as regards powers to appoint an alternate and remuneration) be subject in all respects to the provisions of these Bye-Laws relating to Directors and shall alone be responsible to the Company for his acts and defaults and shall not be deemed to be the agent of or for any Director for whom he is alternate. An Alternate Director may be paid expenses and shall be entitled to be indemnified by the Company to the same extent, mutatis mutandis, as if he were a Director. Every person acting as an Alternate Director shall have one vote for each Director for whom he acts as alternate (in addition to his own vote if he is also a Director). The signature of an Alternate Director to any resolution in writing of the Board or a committee of the Board shall, unless the terms of his appointment provide to the contrary, be as effective as the signature of the Director or Directors to whom he is alternate.

25

26. PROCEEDINGS OF THE BOARD

26.1 The Directors may meet for the transaction of business, adjourn and otherwise regulate their meetings as they see fit.

26.2 A meeting of the Directors may be convened by a Director or the Secretary upon his own initiative. The Secretary shall convene a meeting of the Directors whenever he is required so to do by any Director.

26.3 Reasonable notice shall be given of all meetings of the Directors. Notice to Directors shall, when practicable, be given by facsimile or telex and such facsimile or telex shall contain a summary of the agenda of the particular meeting. If notice by facsimile or telex is impractical, notice may be given by telephone.

26.4 Notwithstanding the provisions of Bye-law 26.3, Directors may waive notice of any meeting either prospectively or retrospectively. A waiver of notice shall be sufficient if it is by facsimile, by telex or in writing.

26.5 The quorum necessary for the transaction of the business of the Directors shall be a majority of the Directors at the relevant time, provided that the Managing Directors are not in the majority of the Directors present or deemed to be present at the meeting and counted in the quorum. Any Director who ceases to be a Director at a Board meeting may continue to be present and to act as a Director and be counted in the quorum until the termination of the Board meeting if no other Director objects and if otherwise a quorum of Directors would not be present.

26.6 A Director shall be treated as present in person at a meeting of the Board if he is in communication with the meeting by conference telephone or other communication equipment permitting those attending the meeting to hear one another. Such Director shall be counted in the quorum of the meeting and shall be entitled to vote thereat. A meeting of the Directors to which this Bye-Law applies shall be deemed to take place where the majority of those participating is assembled or, if there is no majority, at the place where the Chairman of the meeting, is present.

26.7 All questions arising at any Board meeting shall be decided by a majority of the Directors present (including pursuant to Bye-law 26.6) and voting in favour thereof, provided that such majority includes at least one Director who is not a Managing Director.

26.8 So long as a quorum of Directors remains in office, the continuing Directors may act notwithstanding any vacancy in the Board but, if no quorum of Directors remains, the continuing Director(s) shall be deemed to be a quorum for the purposes of filling a casual

26

vacancy pursuant to Bye-law 23.7 or calling a general meeting. If there be no Directors able or willing to act, then any two (2) Shareholders may summon a general meeting for the purpose of appointing Directors.

26.9 The Board may elect a Chairman of the Board from amongst its members who shall not be a Managing Director. If no Chairman of the Board is elected or is absent, the President (if any) shall be Chairman. If at any meeting neither the Chairman of the Board nor the President (if any) is present within five minutes after the time appointed for holding the same, the Directors present may choose one of their number to be Chairman of the meeting. The Board may also create and designate such other positions and titles that it considers appropriate or necessary for the purpose of organising more efficiently the Company’s corporate procedures and governance.

26.10 A resolution in writing signed by all the Directors for the time being entitled to receive notice of a meeting of the Board or by all the members of a committee for the time being shall be as valid and effectual as a resolution passed at a meeting of the Board or, as the case may be, of such committee duly called and constituted. Such resolution may be contained in one document or in several documents in like form each signed by one or more of the Directors or members of the committee concerned.

26.11 A meeting of the Directors for the time being at which a quorum is present shall be competent to exercise all powers and discretions for the time being exercisable by the Directors.

26.12 All acts done by the Board or by any committee or by any person acting as a Director or member of a committee or any person duly authorised by the Board or any committee, shall, notwithstanding that it is afterwards discovered that there was some defect in the appointment of any member of the Board or such committee or person acting as aforesaid or that they or any of them were disqualified or had vacated their office, be as valid as if every such person had been duly appointed and was qualified and had continued to be a Director, member of such committee or person as authorised.

26.13 The Resident Representative shall be entitled to attend and speak at any meeting of the Directors.

27. DELEGATION OF THE BOARD’S POWERS

27.1 The Directors may delegate any of their powers subject to such directions and restrictions as the Directors may think proper and may engage any person to carry out the purposes of the Company in any way whatsoever.

27.2 Without limiting the generality of Bye-law 27.1, the Directors may from time to time appoint registrar and transfer agents of the Company and/or administrators and/or custodians and/or managers and/or investment advisors or consultants.

27.3 The Directors may from time to time, and at any time, by power of attorney, appoint any company, firm or person, or any fluctuating body of persons, whether nominated directly or indirectly by the Directors, to be the attorney or attorneys of the Company for such purposes and with such powers, authorities and discretions (not exceeding those vested in or exercisable by the Directors under these Bye-Laws) and for such period and subject to such conditions as they may think fit, and any such power of attorney may contain such provisions for the protection and convenience of persons dealing with any such attorney as the Directors may think fit, and may also authorise any such attorney to sub-delegate all or any of the powers, authorities and discretions vested in him.

27.4 The Board may from time to time entrust to and confer upon any Director or officer any of the powers exercisable by it upon such terms and conditions with such restrictions as it thinks

27

fit, and either collaterally with, or to the exclusion of, its own powers, and may from time to time revoke or vary all or any of such powers but no person dealing in good faith and without notice of such revocation or variation shall be affected thereby.

27.5 The Board may from time to time delegate any of its powers, authorities and discretions to committees, consisting of such member or members of its body as it thinks fit. Any committee so formed shall, in the exercise of the powers, authorities and discretions so delegated, conform to any regulations, including without limitation, quorum restrictions which may be imposed upon it by the Board.

(a) In particular, the Board shall form an audit committee (the “Audit Committee”) consisting of at least three Independent Directors. The quorum of the Audit Committee shall be a majority of the members of the Audit Committee and decisions of such Audit Committee shall require the affirmative vote of a majority of Independent Directors present and voting thereon.

(b) The meetings and proceedings of any committee consisting of two or more persons shall be governed mutatis mutandis by the provisions contained in these Bye-Laws for regulating the meetings and proceedings of the Directors so far as the same are applicable and are not superseded by any regulations imposed by the Directors or by any provisions in the resolution establishing the committee.

27.6 The Directors may establish any committees (not being committees consisting solely of Directors to which Bye-law 27.5 applies), local boards or agencies for managing any of the affairs of the Company, either in Bermuda or elsewhere, and may appoint any persons to be members of such committees, local boards or agencies, and may fix their remuneration and may delegate to any such committee, local board or agency any of the powers, authorities and discretions vested in the Directors, with power to sub-delegate and may authorise the members of any local board, or any of them, to fill any vacancies therein, and to act notwithstanding vacancies, and any such appointment or delegation may be made upon such terms and subject to such conditions as the Directors may think fit, and the Directors may remove any persons so appointed, and may annul or vary any such delegation, but no person dealing in good faith and without notice of any such annulment or variation shall be affected thereby.

28. DIRECTORS’ INTERESTS

28.1 A Director may hold any other office or place of profit under the Company (other than the office of Auditor) in conjunction with his office of Director for such period and subject to the relevant provisions of the Companies Acts upon such terms as to remuneration and otherwise as the Directors shall approve.

28.2 A Director may act by himself or his firm in a professional capacity for the Company (otherwise than as Auditor), and he or his firm shall be entitled to remuneration for professional services as if he were not a Director.

28.3 Subject to the Companies Acts and the Bye-Laws, no Director or intending Director shall be disqualified by his office from contracting with the Company either with regard to his tenure of any office or place of profit or as vendor, purchaser or otherwise, nor shall any such contract or any contract or arrangement entered into by or on behalf of the Company in which any Director is in any way interested be liable to be avoided, nor shall any Director so contracting or being so interested be liable to account to the Company for any profit realised by any such contract or arrangement by reason of such Director holding that office, or of the fiduciary relationship thereby established. A Director who to his knowledge is in any way, whether directly or indirectly, interested in a contract or arrangement or proposed contract or arrangement with the Company shall declare the nature and extent of his interest at the

28

meeting of the Directors at which the question of entering into the contract or arrangement is first taken into consideration, or if the Director was not at the date of that meeting interested in the proposed contract or arrangement, then at the next meeting of the Directors held after he becomes so interested, and in the case where the Director becomes interested in a contract or arrangement after it is made then at the first meeting of the Directors held after he becomes so interested.

28.4 Any Director may continue to be or become a director, managing director, manager or other officer or member of any company promoted by the Company or any other company in which the Company may be interested, and no such Director shall (unless otherwise agreed) be accountable for any remuneration or other benefits received by him as a director, managing director, manager or other officer or member of any such other company. The Directors may exercise the voting powers conferred by the shares in any other company held or owned by the Company, or exercisable by them as directors of such other company, in such manner in all respects as they think fit (including the exercise thereof in favour of any resolution appointing themselves or any of them directors, managing directors, managers or other officers of such company, or voting or providing for the payment of the remuneration to the directors, managing directors, managers or other officers of such company), and subject to the provisions of this Bye-Law, any Director of the Company may vote in favour of the exercise of such voting rights in the manner aforesaid, notwithstanding that he may be, or be about to be, appointed a director, managing director, manager or other officer of such other company and as such is or may become interested in the exercise of such voting rights in the manner aforesaid.

28.5 Save as provided herein, a Director may vote in respect of (aa) his appointment to hold any office or place of profit under the Company or (bb) the arrangement of the terms of any such appointment or in respect of any contract or arrangement in which he is materially interested (otherwise than by virtue of his interests in Shares or debentures or other securities of or otherwise in or through the Company) and shall be counted in the quorum at the meeting in relation to any resolution on which he is otherwise debarred from voting provided that he declares the nature and extent of his interest to the Board.

28.6 Where proposals are under consideration concerning the appointment (including fixing or varying the terms of appointment) of two or more Directors to offices or employments with the Company or any company in which the Company is interested, such proposals may be decided and considered in relation to such Director separately and in such cases each of the Directors concerned shall be entitled to vote (and be counted in the quorum) in respect of each resolution except that concerning his own appointment.

28.7 If any question shall arise at any meeting as to the materiality of a Director’s interest or as to the entitlement of any Director to vote and such question is not resolved by his voluntarily agreeing to abstain from voting, such question shall be referred to the Chairman of the meeting and his ruling in relation to any other Director shall be final and conclusive except in a case where the nature or extent of the interests of the Director concerned have not been fairly disclosed.

28.8 Subject to the Companies Acts and any further disclosure required thereby a general notice in writing to the Directors by a Director or officer declaring that he is a member of any specified company or firm and is to be regarded as interested in any contract or arrangement which may be made with that company or firm, shall (if such Director or officer shall give the same at a meeting of the Directors or shall take reasonable steps to secure that the same is brought up and read at the next meeting of the Directors after it is given) be a sufficient declaration of interest in relation to any contract or arrangement so made.

28.9 The Company may by Resolution suspend or relax the provisions of this Bye-Law to any extent or ratify any transaction not duly authorised by reason of a contravention of this Bye-Law.

29

29. DIRECTORS’ FEES AND ADDITIONAL REMUNERATION AND EXPENSES

29.1 The Directors shall be entitled to such remuneration as may be voted to them by the Company in general meeting and in the absence of a determination to the contrary in General Meeting, such fees shall be deemed to accrue from day to day.

30. POWERS AND DUTIES OF THE BOARD

30.1 Subject to the provisions of the Memorandum, the Companies Acts and these Bye-Laws and to any directions given by the Company in General Meeting, the Board shall manage the business of the Company and may exercise all the powers of the Company.

Every such cheque or warrant shall, unless the holder or joint holders otherwise direct, be made payable to the order of the holder or, in the case of joint holders, to the order of the holder whose name stands first in the Register in respect of such Shares, and shall be sent at his or their risk and payment of the cheque or warrant by the bank on which it is drawn shall constitute a good discharge to the Company. Any one of two or more joint holders may give effectual receipts for any dividends, distributions or other monies payable or property distributable in respect of the Shares held by such joint holders.

35.7 Any dividend (or distribution out of contributed surplus) unclaimed for a period of six years from the date of declaration of such dividend or distribution shall be forfeited and shall revert to the Company and the payment by the Board of any unclaimed dividend, distribution, interest or other sum payable on or in respect of the share into a separate account shall not constitute the Company a trustee in respect thereof.

34

such difficulty as it thinks expedient, and in particular, may authorise any person to sell and transfer any fractions altogether, and may fix the value for distribution or dividend purposes of any such specific assets and may determine that cash payments shall be made to any Shareholders upon the footing of the values so fixed in order to secure equality of distribution and may vest any such specific assets in trustees as may seem expedient to the Board

36. RESERVES

36.1 The Board may, before recommending or declaring any dividend (or distribution out of contributed surplus), set aside such sums as it thinks proper as reserves which shall, at the discretion of the Board, be applicable for any purpose of the Company and pending such application may, also at such discretion, either be employed in the business of the Company or be invested in such investments as the Board may from time to time think fit. The Board may also without placing the same to reserve carry forward any sums which it may think it prudent not to distribute.

37. CAPITALISATION OF PROFITS

37.1 Subject to the Companies Acts, the Board may, at any time and from time to time, resolve to capitalise all or any part of any amount for the time being standing to the credit of any reserve or fund which is available for distribution or to the credit of any share premium account or any capital redemption reserve fund and set that amount free for distribution amongst the Shareholders or any class of Shareholders who would be entitled thereto if distributed by way of dividend and in the same proportions on the footing that the same be not paid in cash but be applied either in or towards paying up amounts for the time being unpaid on any shares in the Company held by such Shareholders respectively or in payment up in full of unissued shares, debentures or other obligations of the Company, to be allotted and distributed credited as fully paid amongst such Shareholders or partly in one way and partly in the other. Provided that for the purpose of this Bye-Law, a share premium account and a capital redemption reserve fund may be applied only in paying up of unissued Shares to be issued to such Shareholders credited as fully paid and provided further that any sum standing to the credit of a share premium account may only be applied in crediting as fully paid shares of the same class as that from which the relevant share premium was derived.

37.2 The Board may make all appropriations and applications of the profits or sums resolved by it to be capitalised, and all allotments and issues of fully paid Shares, if any, and generally may do all acts and things required to give effect thereto, with full power to the Board to make such provision by the issue of fractional certificates or by payment in cash or otherwise as they think fit for the case of shares or debentures becoming distributable in fractions and also to authorise any person to enter on behalf of all the Shareholders entitled to the benefit of such appropriations and applications into an agreement with the Company providing for the allotment to them respectively, credited as fully paid up, of any further Shares to which they may be entitled upon such capitalisation, and any agreement made under such authority shall be effective and binding on all such Shareholders.

36

39.2 The remuneration of the Auditor shall be determined by the Shareholders or by the Directors if so authorised by the Shareholders.

The Company may designate mechanisms for validating any such document, and any such document not so validated by use of such mechanisms shall be deemed not to have been received by the Company.

41.2 Any Shareholder may notify the Company of an address for the purpose of receiving electronic communications from the Company, and having done so shall be deemed to have agreed to receive by electronic communication notices and other documents from the Company of the kind to which the address relates. In addition, if a Shareholder notifies the Company of his e-mail address, the Company may satisfy its obligation to send him any notice or other document by (a) publishing such notice or other document on a website and (b) notifying him by e-mail to that e-mail address that such notice or document has been so published.

The liquidator may, with the like authority, vest any part of the assets in trustees upon such trusts for the benefit of Shareholders as the liquidator, with the like authority, shall think fit, and the liquidation of the Company may be closed and the Company dissolved, but so that no Shareholder shall be compelled to accept any shares or other asset in respect of which there is a liability.

(d) after such interested person became an interested person and prior to the consummation of such Business Combination: (i) such interested person shall have taken steps to ensure that the Board includes at all times representation by Continuing Directors (as hereinafter defined) proportionate to the ratio that the number of shares carrying voting rights in the Company from time to time owned by Shareholders who are not interested persons bears to all shares carrying voting rights in the Company outstanding at the time in question (with a Continuing Director to occupy any resulting fractional position among the Directors); (ii) such interested person shall not have acquired from the Company or any subsidiary of the Company, directly or indirectly, any Shares (except (x) upon conversion of convertible securities acquired by it prior to becoming an interested person, or (y) as a result of a pro rata share dividend, stock split or division or subdivision of shares, or (z) in a transaction consummated on or after 7 June 2001 and which satisfied all applicable requirements of this Bye-Law 45); (iii) such interested person shall not have acquired any additional shares, or rights over shares, carrying voting rights or securities convertible into or exchangeable for shares, or rights over shares, carrying voting rights except as a part of the transaction which resulted in such interested person becoming an interested person; and (iv) such interested person shall not have (x) received the benefit, directly or indirectly (except proportionately as a Shareholder), of any loans, advances, guarantees, pledges or other financial assistance or tax credits provided by the Company or any subsidiary of the Company, or (y) made any major change in the Company’s business or equity capital structure or entered into any contract, arrangement or understanding with the Company except any such change, contract, arrangement or understanding as may have been approved by the favourable vote of not less than a majority of the Continuing Directors; and

(e) a proxy statement complying with the requirements of the United States Securities Exchange Act of 1934, as amended, shall have been mailed to all holders of shares carrying voting rights for the purpose of soliciting approval by the Shareholders of such Business Combination. Such proxy statement shall contain at the front thereof, in a prominent place, any recommendations as to the advisability (or inadvisability) of the Business Combination which the Continuing Directors, or any of them, may have furnished in writing and, if deemed advisable by a majority of the Continuing Directors, an opinion of a reputable investment banking firm as to the adequacy (or inadequacy) of the terms of such Business Combination from the point of view of the holders of shares carrying voting rights other than any interested person (such investment banking firm to be selected by a majority of the Continuing Directors, to be furnished with all information it reasonably requests, and to be paid a reasonable fee for its services upon receipt by the Company of such opinion).

46. CERTAIN CONSEQUENCES ON BECOMING AN INTERESTED PERSON

46.1 Except as permitted by Bye-Law 46.2, if at any time a person acquires or becomes the beneficial owner of any shares, or rights over shares, carrying voting rights in the Company which, alone or when aggregated with any shares or rights over shares which such person then already holds or of which such person is then already the beneficial owner, would carry fifteen per cent (15%) or more of the total voting rights which may be cast at any general meeting of the Company (such fifteen per cent (15%) of the total voting rights which may be cast at any general meeting being herein referred to as the “threshold”), then such person shall not be entitled, in respect of that portion of any shares, or rights over shares, carrying voting rights in the Company held or beneficially owned by him in excess of the threshold, (i) to vote such shares at any general meeting of the Company either personally or by proxy or by his attorney or, if a company or a corporation, by its duly authorised representative or to exercise any other right conferred by shareholding in the Company in relation to general meetings of the Company as to which the record date or scheduled meeting date falls within a period of five (5) years from the date such person first acquired or became the beneficial owner of shares, or rights over shares, carrying voting rights in excess of the threshold, or (ii) to give any written consent with respect thereto for a period of five (5) years from the date such person first acquired or became the beneficial owner of shares, or rights over shares, carrying voting rights in excess of the threshold. For purposes of the foregoing sentence, no shares, or rights over shares, carrying voting rights in the Company held or beneficially owned by the Company or any of its subsidiaries shall be aggregated with such shares or rights over shares held or beneficially owned by any other person.

46.2 The restrictions contained in Bye-Law 46.1 shall not apply to the Company or any of its subsidiaries or:

(a) any person who, on 7 June 2001, holds or is the beneficial owner of shares, or rights over shares, carrying voting rights in excess of the threshold and continues at all times thereafter to hold or be the beneficial owner of shares, or rights over shares, carrying voting rights in excess of the threshold; or

(b) to any person who holds or is the beneficial owner of shares, or rights over shares, carrying voting rights in the Company if the acquisition by such person of such shares or rights over shares in excess of the threshold is approved prior to the threshold being exceeded (i) by resolution adopted in general meeting by a majority of eighty per cent (80%) of those present and voting at a general meeting of the Company not being votes attached to shares held or beneficially owned by any person holding shares or rights over shares with respect to which such vote is being taken, or (ii) by resolution adopted by a majority of the Continuing Directors followed by a Resolution adopted by in excess of fifty per cent (50%) of the shares carrying voting rights in the Company not held or beneficially owned by any person holding shares or rights over shares with respect to which such vote is being taken.

46.3 The Company, whether acting through the Directors or by its Shareholders generally, shall have no power to propose or enter into any compromise or arrangement pursuant to the Companies Acts providing for any revocation, alteration or amendment of this Bye-Law 46 or any other amendment of its Memorandum of Association or these Bye-Laws which could have the effect of modifying or circumventing this Bye-Law 46.

46

46.4 Any revocation, alteration or amendment of this Bye-Law 46, or any other revocation, alteration or amendment of the Company’s Memorandum of Association or these Bye-Laws which would have the effect of modifying or permitting circumvention of this Bye-Law 46, shall require a majority of eighty per cent (80%) of those present and voting at a general meeting of the Company; provided, however, that this Bye-Law 46.4 shall not apply to, and such eighty per cent (80%) majority shall not be required for, any such revocation, alteration or amendment recommended to Shareholders by the favourable vote of not less than a majority of the Continuing Directors.

46.5 Nothing contained in this Bye-Law 46 shall be construed to relieve any interested person from any fiduciary obligation imposed by law.

47. ALTERATION OF BYE-LAWS

47.1 The Directors may from time to time revoke, alter, amend or add to these Bye-Laws; provided that no such revocation, alteration, amendment or addition shall be operative unless and until it is confirmed by an Extraordinary Resolution at a subsequent general meeting of the Company except that Bye-Laws 23.1 and 23.4 and this Bye-Law 47 shall not be revoked, altered or amended and no new Bye-Law shall become operative which alters the effect of any of them until the same has been approved by a majority of eighty per cent (80%) of those present and voting at a general meeting of the Company and Bye-Laws 45 and 46 shall not be revoked, altered or amended and no new Bye-Laws shall become operative which alters the effect of either of them except as provided in such Bye-Laws.

47.2 In the event of the successful consummation of a Business Combination, the Board of Directors, immediately upon receiving a written notice from Tsakos Energy Management Limited, shall take steps to convene a meeting of Shareholders in order to change the name of the Company so as to exclude any reference to Tsakos.

Basis of Presentation [Abstract]

Basis of Presentation

1.Basis of Presentation

The accompanying unaudited consolidated financial statements of Tsakos Energy Navigation Limited (the “Holding Company”) and subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 6-K and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation have been included. Operating results for the six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.

The consolidated balance sheet as of December 31, 2014 has been derived from the audited financial statements included in the Company’s annual report on Form 20-F filed with the Securities and Exchange Commission on April 8, 2015 (“Annual Report”), but does not include all of the footnotes required by generally accepted accounting principles for complete financial statements.

A discussion of the Company’s significant accounting policies can be found in Note 1 of the Company’s consolidated financial statements included in the Annual Report. There have been no material changes to these policies in the six-month period ended June 30, 2015.

New Accounting Pronouncements:

(a)Consolidation: In February 2015, the FASB issued Accounting Standards Update (“ASU”) No. 2015-02-Consolidation. The amendments in this ASU affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. Management believes that this standard will not have a material effect on the Company’s financial position.

(b)Debt Issuance costs: In April 2015, the FASB issued ASU No. 2015-03-Interest-Imputation of Interest, to simplify the presentation of debt issuance costs. The amendments in this ASU would require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. Management believes that this standard will not have a material effect on the Company’s financial position.

(c)Fair Value Measurement: In May 2015, the FASB issued ASU No. 2015-07-Fair Value Measurement, which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using net asset value per share of the investment. Management believes that this standard will not have a material effect on the Company’s financial position.

(d) Revenue from Contracts with Customers: In May 2015, the FASB issued ASU No.2015-14-Revenue from Contracts with Customers, which defers the effective date of ASU 2014-09. Management believes that this standard will not have a material effect on the Company’s financial position.

Commitments and Contingencies

10.Commitments and Contingencies

As at June 30, 2015, the Company had under construction nine aframax tankers, two LR1 product tankers, one shuttle tanker and one LNG carrier. The total contracted amount remaining to be paid for the thirteen vessels under construction, plus the extra costs agreed as at June 30, 2015 was $641,325. Scheduled remaining payments as at June 30, 2015 were $49,486 from July to December 2015, $377,701 in 2016, and $214,138 in 2017. At June 30, 2015, there is a prepaid amount of $1,650 under an old shipbuilding contract which was terminated in 2014, which will be used against the contract price of future new buildings currently being discussed between the Company and the shipyard.

In the ordinary course of the shipping business, various claims and losses may arise from disputes with charterers, agents and other suppliers relating to the operations of the Company’s vessels. Management believes that all such matters are either adequately covered by insurance or are not expected to have a material adverse effect on the Company’s results of operations or financial condition.

 Charters-out

The future minimum revenues of vessels in operation at June 30, 2015, before reduction for brokerage commissions, expected to be recognized on non-cancelable time charters are as follows:

Period/Year	Amount
July to December 2015	86,204
2016	129,345
2017	150,602
2018	156,680
2019 to 2029	806,200
Minimum charter payments	1,329,031

These amounts do not assume any off-hire.

Financial Instruments [Abstract]

Financial Instruments

11.Financial Instruments

(a)Interest rate risk: The Company is subject to interest rate risk associated with changing interest rates with respect to its variable interest rate term loans and credit facilities as described in Notes 5 and 6.

(b)Concentration of credit risk: Financial Instruments that are subject to credit risks consist principally of cash, trade accounts receivable, investments, and derivatives. The Company places its temporary cash investments, consisting mostly of deposits, primarily with high credit qualified financial institutions. The Company performs periodic evaluations of the relative credit standing of those financial institutions that are considered in the Company’s investment strategy. The Company limits its credit risk with accounts receivable by performing ongoing credit evaluations of its customers’ financial condition and generally does not require collateral for its accounts receivable and does not have any agreements to mitigate credit risk. The Company limits the exposure of non-performance by counterparties to derivative instruments by diversifying among counterparties with high credit ratings, and performing periodic evaluations of the relative credit standing of the counterparties.

(c)Fair value: The carrying amounts reflected in the accompanying Consolidated Balance Sheet of cash and cash equivalents, restricted cash, trade receivables and accounts payable approximate their respective fair values due to the short maturity of these instruments. The fair value of long-term bank loans with variable interest rates approximate the recorded values, generally due to their variable interest rates. The present value of the future cash flows of the portion of one long-term bank loan with a fixed interest rate is estimated to be approximately $36,566 as compared to its carrying amount of $37,410. The Company performs relevant enquiries on a periodic basis to assess the recoverability of the long-term investment and estimates that the amount presented on the accompanying balance sheet approximates the amount that is expected to be received by the Company in the event of sale of that investment.

The fair values of the one long-term bank loan with a fixed interest rate, the interest rate swap agreements, and bunker swap agreements, put option agreements and call option agreements discussed in Note 6 above are determined through Level 2 of the fair value hierarchy as defined in FASB guidance for Fair Value Measurements and are derived principally from or corroborated by observable market data, interest rates, yield curves and other items that allow value to be determined.

The estimated fair values of the Company’s financial instruments, other than derivatives at June 30, 2015 and December 31, 2014, are as follows:

	Carrying Amount June 30, 2015	Fair Value June 30, 2015	Carrying Amount December 31, 2014	Fair Value December 31, 2014
Financial assets/(liabilities)
Cash and cash equivalents	278,927	278,927	202,107	202,107

Less - current portion	(300,564)	(228,492)
Long-term portion	1,103,861	1,189,844

(a)Credit facilities

As at June 30, 2015, the Company had six open reducing revolving credit facilities, all of which are reduced in semi-annual installments, and two open facilities which have both a reducing revolving credit component and a term bank loan component, with balloon payments due at maturity between December 2015 and April 2019. At June 30, 2015 there is no available unused amount.

Interest is payable at a rate based on the London interbank offered rate (“LIBOR”) plus a spread. At June 30, 2015, the interest rates on these facilities ranged from 0.96% to 5.19%.

(b)Term bank loans

Term loan balances outstanding at June 30, 2015 amounted to $710,339. These bank loans are payable in U.S. Dollars in quarterly or semi-annual installments, with balloon payments due at maturity between October 2016 and February 2025. Interest rates on the outstanding loans as at June 30, 2015, are based on LIBOR plus a spread.

On April 22, 2015, the Company signed a new five-year term bank loan for $35,190 relating to the pre and post delivery financing of the first LR1 tanker under construction. The first drawdown of $7,038 was made on April 23, 2015 for the payment of the second installment to the ship building yard. The loan is repayable in ten consecutive semi-annual installments of $977.5, commencing six months after the delivery of the vessel, plus a balloon of $25,415 payable together with the last installment.

On April 22, 2015, the Company signed a new seven-year term bank loan for $35,190 relating to the pre and post delivery financing of the second LR1 tanker under construction. The first drawdown of $7,038 was made on April 22, 2015 for the payment of the second installment to the ship building yard. The loan is repayable in fourteen consecutive semi-annual installments equal to 1/32nd of the amount drawn under the loan, commencing six months after the delivery of the vessel, plus a balloon sufficient to repay the loan in full.

On May 25, 2015, the Company signed a new eight-year term bank loan for $73,500 relating to the pre and post delivery financing of one shuttle tanker under construction. The first drawdown of $9,800 was made on May 26, 2015 for the payment of the second installment to the ship building yard. The loan is repayable in sixteen consecutive semi-annual installments of $2,300, commencing six months after the delivery of the vessel, plus a balloon of $36,700 payable together with the last installment.

At June 30, 2015, interest rates on these term bank loans ranged from 1.77% to 4.03%.

The weighted-average interest rates on the above executed loans for the applicable periods were:

Three months ended June 30, 2015	2.26%
Three months ended June 30, 2014	2.43%
Six months ended June 30, 2015	2.24%
Six months ended June 30, 2014	2.44%

The above revolving credit facilities and term bank loans are secured by first priority mortgages on all vessels, by assignments of earnings and insurances of the respectively mortgaged vessels, and by corporate guarantees of the relevant vessel-owning subsidiaries.

The loan agreements include, among other covenants, covenants requiring the Company to obtain the lenders’ prior consent in order to incur or issue any financial indebtedness, additional borrowings, pay dividends in an amount more than 50% of cumulative net income (as defined in the related agreements), sell vessels and assets, and change the beneficial ownership or management of the vessels. Also, the covenants require the Company to maintain a minimum liquidity, not legally restricted, of $100,020 at June 30, 2015 and $79,563 at December 31, 2014, a minimum hull value in connection with the vessels’ outstanding loans and insurance coverage of the vessels against all customary risks. Three loan agreements require the Company to maintain throughout the security period, an aggregate credit balance in a deposit account of $3,250 and two other loan agreements a monthly pro rata transfer to a retention account of any principal due but unpaid.

As at June 30, 2015 and December 31, 2014, the Company and its wholly and majority owned subsidiaries were compliant with the financial covenants in its loan agreements, including the leverage ratio and the value-to-loan requirements and all other terms and covenants, except in the case of the value-to-loan requirements in one of its loan agreements with an outstanding balance of $30,400 as of June 30, 2015 ($31,700 as of December 31, 2014). The value-to-loan ratio will be satisfied with the repayment of the next two scheduled semi-annual installments, amounting to $1,300 each, on August 4, 2015 and February 4, 2016 respectively and therefore, no additional amount has been reclassified in the current liabilities at June 30, 2015.

The Company’s liquidity requirements relate primarily to servicing its debt, funding the equity portion of investments in vessels and funding expected capital expenditure on dry-dockings and working capital. As of June 30, 2015, the Company’s working capital (non-restricted net current assets), amounted to $25,901 ($49,817 deficit at December 31, 2014). The Company’s working capital has returned to a working surplus despite the two loan facilities which are reaching their maturity in December 2015 and June 2016 amounting $119,075 in total, and the loan balance of $52,195 relating to the pre-delivery financing of the LNG carrier Maria Energy,which is falling due in the first quarter of 2016, and the repayment of $23,194 on sale of Delphi and Triathlon which are held for sale at June 30, 2015 (Note 12 (d)). However, on April 22, 2015 the Company raised $81,798 in a public offering of its 8.75% Series D Cumulative Perpetual Preferred Shares, net of underwriter’s commission and other expenses. Net cash flow generated from operations is the Company’s main source of liquidity whereas other management alternatives to ensure service of the Company’s commitments include, but are not limited to, the issuance of additional equity and utilization of suitable opportunities for asset sales, etc. Management believes, such alternatives along with current available cash holdings and cash expected to be generated from the operation of vessels, will be sufficient to meet the Company’s liquidity and working capital needs for a reasonable period of time.

The annual principal payments required to be made after June 30, 2015, are as follows:

Period/Year	Amount
July to December 2015	181,436
2016	265,237

At June 30, 2015, the Company was committed to seven floating-to-fixed interest rate swaps with major financial institutions covering notional amounts aggregating to $296,331, maturing from March 2016 through March 2021 on which it pays fixed rates averaging 3.25% and receives floating rates based on the six-month LIBOR (Note 11).

At June 30, 2015, the Company held six of the seven interest rate swap agreements, designated and qualifying as cash flow hedges, in order to hedge its exposure to interest rate fluctuations associated with its debt covering notional amounts aggregating to $246,081. The fair value of such financial instruments as of June 30, 2015 and December 31, 2014 in aggregate amounted to $8,455 (negative) and $7,046 (negative), respectively. The net amount of cash flow hedge losses at June 30, 2015 that is estimated to be reclassified into earnings within the next twelve months is $3,909.

At June 30, 2015 and December 31, 2014, the Company held one interest rate swap, that did not meet hedge accounting criteria. As such, the changes in its fair values during the first half of 2015 and 2014 have been included in change in fair value of non-hedging financial instruments in the table above, and amounted to a gain of $1,241 and $1,413, respectively.

At June 30, 2015 and December 31, 2014, the Company had four and seven bunker swap agreements respectively, in order to hedge its exposure to bunker price fluctuations associated with the consumption of bunkers by its vessels. The fair value of these financial instruments as of June 30, 2015 and December 31, 2014 was $3,321 (negative) and $9,228 (negative), respectively.

The changes in their fair values during the first half of 2015 and 2014 amounting to $5,907 (positive) and $81 (negative) respectively have been included in change in fair value of non-hedging financial instruments in the table above as such agreements do not meet the hedging criteria.

At June 30, 2015 and December 31, 2014, the Company held three bunker put option agreements in order to reduce the losses of the bunker swap agreements previously entered into. The value of those put options at June 30, 2015 was $534 (positive) and at December 31, 2014 $2,443 (positive). The change in their fair value in the first half of 2015 was $1,909 (negative). In the first half of 2015 the Company entered into two call option agreements for the same reasons as for the put options. The premium paid for the call options was $314 which equals their fair market value at June 30, 2015.

Basis of Presentation (Policies)

Basis of Presentation [Abstract]

New Accounting Pronouncements:

(a)Consolidation: In February 2015, the FASB issued Accounting Standards Update (“ASU”) No. 2015-02-Consolidation. The amendments in this ASU affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. Management believes that this standard will not have a material effect on the Company’s financial position.

(b)Debt Issuance costs: In April 2015, the FASB issued ASU No. 2015-03-Interest-Imputation of Interest, to simplify the presentation of debt issuance costs. The amendments in this ASU would require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. Management believes that this standard will not have a material effect on the Company’s financial position.

(c)Fair Value Measurement: In May 2015, the FASB issued ASU No. 2015-07-Fair Value Measurement, which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using net asset value per share of the investment. Management believes that this standard will not have a material effect on the Company’s financial position.

(d) Revenue from Contracts with Customers: In May 2015, the FASB issued ASU No.2015-14-Revenue from Contracts with Customers, which defers the effective date of ASU 2014-09. Management believes that this standard will not have a material effect on the Company’s financial position.

Long-Term Debt [Line Items]

Debt Instrument Covenant Description

The loan agreements include, among other covenants, covenants requiring the Company to obtain the lenders’ prior consent in order to incur or issue any financial indebtedness, additional borrowings, pay dividends in an amount more than 50% of cumulative net income (as defined in the related agreements), sell vessels and assets, and change the beneficial ownership or management of the vessels. Also, the covenants require the Company to maintain a minimum liquidity, not legally restricted, of $100,020 at June 30, 2015 and $79,563 at December 31, 2014, a minimum hull value in connection with the vessels’ outstanding loans and insurance coverage of the vessels against all customary risks. Three loan agreements require the Company to maintain throughout the security period, an aggregate credit balance in a deposit account of $3,250 and two other loan agreements a monthly pro rata transfer to a retention account of any principal due but unpaid.

Debt Instrument Covenant Compliance

As at June 30, 2015 and December 31, 2014, the Company and its wholly and majority owned subsidiaries were compliant with the financial covenants in its loan agreements, including the leverage ratio and the value-to-loan requirements and all other terms and covenants, except in the case of the value-to-loan requirements in one of its loan agreements with an outstanding balance of $30,400 as of June 30, 2015 ($31,700 as of December 31, 2014). The value-to-loan ratio will be satisfied with the repayment of the next two scheduled semi-annual installments, amounting to $1,300 each, on August 4, 2015 and February 4, 2016 respectively and therefore, no additional amount has been reclassified in the current liabilities at June 30, 2015.

(a)Tsakos Energy Management Limited (the “Management Company”): The Holding Company has a Management Agreement (“Management Agreement”) with the Management Company, a Liberian corporation, to provide overall executive and commercial management of its affairs for a monthly fee. Per the Management Agreement of March 8, 2007, effective from January 1, 2008, there is a prorated adjustment if at the beginning of each year the Euro has appreciated by 10% or more against the U.S. Dollar since January 1, 2007. In addition, there is an increase each year by a percentage figure reflecting 12 month Euribor, if both parties agree. In the first six months of 2015 and 2014 monthly fees for operating vessels are $27.5, for vessels chartered out, $20.4 for vessels on a bare-boat basis, and $35.8 for the LNG carrier, of which $10.0 is paid to the Management Company and $25.8 to a third party manager. Monthly management fees for the DP2 shuttle tankers have been agreed to $35.0, per vessel. Since the expiry of the bareboat charter of the VLCC Millennium on July 30, 2013, management fees for this vessel are $27.5 per month, of which $13.7 are payable to a third party manager. Management fees for the suezmax Eurochampion 2004 are $27.5 per month, of which, $12.0 are paid to a third party manager. In addition to the Management fee, the Management Agreement provides for an incentive award to the Management Company, which is at the absolute discretion of the Holding Company’s Board of Directors. In the first six months of 2015 an award of $1,142 was granted to the Management Company and is included in General and Administrative expenses in the accompanying Consolidated Statement of Operations. No such award was granted in the first six months of 2014. In addition, a special award of $425 was paid to the Management Company in relation to capital raising offerings during the first six months of 2015 and $400 in the first six months of 2014. These awards have been included as a deduction of additional paid in capital in the accompanying Financial Statements.

The Holding Company and the Management Company have certain officers and directors in common. The President, who is also the Chief Executive Officer and a Director of the Holding Company, is also the sole stockholder of the Management Company. The Management Company may unilaterally terminate its Management Agreement with the Holding Company at any time upon one year’s notice. In addition, if even one director was elected to the Holding Company’s Board of Directors without having been recommended by the existing Board, the Management Company would have the right to terminate the Management Agreement on ten days’ notice, and the Holding Company would be obligated as at June 30, 2015 to pay the Management Company an amount of approximately $166,285 calculated in accordance with the terms of the Management Agreement. Under the terms of the Management Agreement between the Holding Company and the Management Company, the Holding Company may terminate the Management Agreement only under specific circumstances, without the prior approval of the Holding Company’s Board of Directors.

Estimated future management fees payable over the next ten years under the Management Agreement, exclusive of any incentive awards and based on existing vessels and known vessels scheduled for future delivery, as at June 30, 2015 are:

Period/Year	Amount
July to December 2015	9,342
2016	18,744
2017	19,451
2018	19,672
2019	19,672
2020 to 2025	108,196
	195,077

Management fees for vessels are included in the accompanying Consolidated Statements of Operations. Also, under the terms of the Management Agreement, the Management Company provides supervisory services for the construction of new vessels for a monthly fee of $20.4. These fees in total amounted to $1,550 and $979 during the six months ended June 30, 2015 and 2014, respectively, and are either accounted for as part of construction costs for delivered vessels or are included in Advances for vessels under construction.

(b)Tsakos Columbia Shipmanagement S.A. (“TCM”): The Management Company appointed TCM to provide technical management to the Company’s vessels from July 1, 2010. TCM is owned jointly and in equal part by related party interests and by a private German Group. TCM, with the consent of the Holding Company, may subcontract all or part of the technical management of any vessel to an alternative unrelated technical manager.

Effective July 1, 2010, the Management Company, at its own expense, pays technical management fees to TCM, and the Company bears and pays directly to TCM most of its operating expenses, including repairs and maintenance, provisioning and crewing of the Company’s vessels, as well as certain charges which are capitalized or deferred, including reimbursement of the costs of TCM personnel sent overseas to supervise repairs and perform inspections on Company vessels. The Company also pays to TCM certain fees to cover expenses relating to internal control procedures and information technology services which are borne by TCM on behalf of the Company.

(c)Tsakos Shipping and Trading S.A. (“Tsakos Shipping”):

Tsakos Shipping provides chartering services for the Company’s vessels by communicating with third party brokers to solicit research and propose charters. For this service, the Company pays to Tsakos Shipping a chartering commission of approximately 1.25% on all freights, hires and demurrages. Such commissions are included in Voyage expenses in the accompanying Consolidated Statements of Operations. Tsakos Shipping also provides sale and purchase of vessels brokerage service. For this service, Tsakos Shipping may charge a brokerage commission. In the first six months of 2015 there were no sales or purchases of vessels. In the first six months of 2014 the suezmax tanker Eurovision was acquired. Tsakos Shipping may also charge a fee of $200 (or such other sum as may be agreed) on delivery of each new-building vessel in payment for the cost of design and supervision of the new-building by Tsakos Shipping. In the first six months of 2015 no such fee was charged. In the first six months of 2014, $200 in aggregate was charged for supervision fees on the DP2 shuttle tankers Rio 2016 and Brasil 2014.

Certain members of the Tsakos family are involved in the decision-making processes of Tsakos Shipping and of the Management Company, and are also shareholders of the Holding Company.

(d)Argosy Insurance Company Limited (“Argosy”): The Company places its hull and machinery insurance, increased value insurance and war risk and certain other insurance through Argosy, a captive insurance company affiliated with Tsakos Shipping.

(e)AirMania Travel S.A. (“AirMania”): Apart from third-party agents, the Company also uses an affiliated company, AirMania, for travel services.
