Subject to results from the long term production test and appraisal drilling, the Company believes the Bretana discovery is potentially at the high end of the June 2012 resource estimate which was: 1C – 11.5 mmbbls; 2C - 31.6 mmbbls; 3C - 88.1 mmbbls. The mid case (2C) represents 43% of the YE12 2P booked reserves, and the high case (3C) 121%. First Production by H2/17 – An early production scenario for Bretana would see the 2014 long term test produce 2,500 to 3,000 bbls/day; a test of the appraisal well would follow in 2015; first production of approximately 10,000 bbls/day would commence in H2/17 and sustainable (five to six years) peak production of 40,000 bbls/day would commence in 2020. Netbacks Strong and CF Impact Material – Netbacks would be $51 to $55 per bbl assuming Brent of $100. 10,000 bbls/day would add, on a proforma basis for illustrative purposes, 50% to our 2014F CFPS, and at 40,000 bbls/day, 185%. Even after tax (which wouldn’t initially be the case given the capital expenditures) the increase would be 35% and 130%, respectively. Forecast – We have included net operating revenue from the planned long term test of Bretana in 2014 (and smaller updates), resulting in our CFPS increasing to $1.50 (diluted) from $1.39 previously. Target Price & Rating – We maintain our Buy rating, and increase our target price to C$9.25 from C$8.00 previously. Risks Gran Tierra has an overall Medium High risk rating. Country risk exposure as it relates to disruptions in the OTA pipeline operations is the greatest risk we have identified, however contingency marketing arrangements have resulted in the Company recently being able to market all of its produced oil through trucking. Catalysts Drilling results from Moqueta 10 are expected in late June; Mayalito 1 will spud in June; Miraflor Oeste 1 will spud in early July; and horizontal drilling on Brazil continues. The Company expects to release a resource/reserve update for the Bretana discovery in Q4/13.

Dividend: 6/10/13 TSX : GTE; AMEX: GTE C$ 0.00 Price C$ 6.53 Target:C$ 9.25 The addition of Moqueta, an early discovery in a larger exploration program, supports the Company’s strategy. 2012 Brazil Reconcavo exploration could result in meaningful growth for Gran Tierra. Capital Structure (C$, mm's) Price History Alpha: Investment Highlights Shares O/S Options Warrants • Acquistion of Petrolifera - In January 2011, Gran Tierra announced an offer to acquire all of the common shares of Petrolifera, which • Strong Balance Sheet - Gran Tierra has consistently maintained a conservative balance sheet. At March 31, 2013 the Company had net positive working capital of $246 million including $236 million in cash, and no debt outstanding. had an all-in cost of US$195 million. Gran Tierra issued 18 million common shares and assumed US$41 million in net debt in connection with this transaction. • Presence in Peru - Gran Tierra has an interest in 3 blocks in the Maranon Basin of NE Peru and 2 blocks in the Ucayali Basin, all of which could materially impact the Company with exploration success. The first exploration well, Kanatari 1, was drilled on Block 128 in Q1/11 but did not encounter any hydrocarbons and was plugged and abandoned and the block was subsequently relinquished. The Company is planning to drill one exploration well in Peru in 2013, Bretana Norte, on Block 95, which was successful. • Brazil Farm-In - In August 2010, the Company farmed in to four exploration blocks located in the onshore Reconcavo Basin of Brazil and in September 2011 farmed in to two offshore blocks in the Camamu-Almada Basin. In December 2011 the first well was drilled on the offshore block, BM-CAL-10, but was dry and abandoned, and it relinquished its interest in that block. A well on the second offshore block is not expected until late 2013. Onshore in the Reconcavo Basin the blocks have the potential to be a meaningful resource development play if early evaluation proves positive. Three more Reconcavo blocks were acquired in the 2013 bid round. • Moqueta Discovery - At YE12 the Moqueta discovery had been assigned net 3P reserves of 19.9 mmbbls, up from 9.9 mmbbls at YE11. Production from Moqueta is expected to increase in 2013/14, offsetting any declines from Costayaco and providing for a continued stable production profile in Colombia. % dil'n 5% 0% 5% Fully Diluted Liquidity (90dMA) D&O % Owned FMR Amber Capital Mgmt Market Capitilization Net Debt (Wkg Cap) Enterprise Value 282.2 15.4 0.0 15.4 297.6 996,000 2.6% 9.2% 7.0% $1,842.8 ($246.1) $1,596.7 115% -15% 100% 52 wk H/L $6.95/$4.10 $7.00 Revenue - net royalties Operating Costs Net Operating Revenue Cash Flow D&D Note: Based on gross sales production. $67.00 $9.70 $57.30 $35.98 $25.98 $67.48 $14.45 $53.02 $37.46 $21.07 $71.88 $16.05 $55.83 $37.63 $21.83 $73.66 $16.52 $57.14 $38.87 $21.25 CFPS - US$ 2013F 2014F Cash Flow Sensitivity WTI (US$1.00) US/CD f/x Oil (1,000 bbls/d) Valuation Parameters Price/CF - Basic Price/CF - Diluted Target Price/CF - Basic Target Price/CF - Diluted - CFPS for above calculation converted to C$ EV/DACF Target EV/DACF EV/boe/d (C$) Target EV/boe/d (C$) Prod/mm shs 2% 3% 2% 3% -3% ($0.070) ($0.099) ($0.043) -1.0% -3.0% 0.9% 2011 2012 2013F 2014F 5.6x 5.8x 7.9x 8.2x 5.7x 5.7x 8.0x 8.1x 4.6x 4.7x 6.6x 6.7x 4.3x 4.4x 6.1x 6.2x $67,626 $100,137 83.7 3.9x 5.8x $56,430 $83,558 100.3 3.3x 5.1x $54,957 $81,377 103.0 $6.00 Assumptions 2011 2012 2013F WTI (US$/bbl) Brent (US$/bbl) F/X (US/CD) $95.11 $111.05 $1.01 $94.15 $111.92 $1.00 $90.00 $105.00 $0.99 Revenue (US$mm's) 500 NPV10 Before Tax - ($mm) Proved 2P -4.6% 3P -6.5% -2.8% Contingent Resources (Block 95, Peru) % Chg '14/'13 1C -8% 2C -7% 3C -8% -7% $5.50 5.0 $5.00 4.0 $4.50 3.0 $4.00 2.0 $3.50 1.0 $3.00 Jun-12 Dana Coffield James Rozon Shane O'Leary Duncan Nightingale Julio Moriera 2014F % Chg '14/'13 Carlos Monges $90.00 0% Rafael Orunesu $105.00 0% $1.00 1% 40,000 $1.50 30,000 $1.00 20,000 Company Website: Company Head Office: 2014F 2011 2,833 424 3,065 15 6,337 2011 2012 % Chg '12/'11 3,587 598 6,368 61 10,614 % of Total 27% 41% 108% 308% 67% 34% 6% 60% 1% 100% 2012 % Chg '11/'10 % Chg '12/'11 20% 21% 20% 14% 18% -13% 5% 15% 0% $180.6 76.0% 24.0% 76.5% 23.5% 80.8% 19.2% 1% -2% 6% -18% 1,127.5 1,573.0 2,513.0 1,418.1 1,632.6 2,284.9 26% 4% -9% -100% -100% -100% 11,500 31,600 88,100 n.m. n.m. n.m. n.m. n.m. n.m.

(GTE-T) 6/10/13 Investment Thesis Gran Tierra presents an opportunity to invest in a well-managed, focused, and disciplined South American producer. The Company’s success at Costayaco, followed by Moqueta, has provided it with the ability to deliver relatively static production out of Colombia at current rates for one more year, and perhaps longer. While still in the preliminary evaluation stages, early indications from the Bretana Norte discovery in Peru suggest that this could also become a meaningful contribution to the Company’s production after 2013. Gran Tierra has established a multi-faceted opportunity base including: exploration in Colombia and Peru; development in Colombia (Moqueta); exploitation in Argentina (the Puesto Morales and Puesto Morales Norte fields); and a potential onshore resource play in Brazil. We believe the depth of the opportunities, potential impact, and varied risk associated with each represents a strong and valuable asset base for the Company. Gran Tierra reports in US$. All amounts below are in US$ unless otherwise noted. Gran Tierra follows the U.S. convention of reporting its production and reserves volumes after royalties (Net After Royalties or NAR). Before royalty volumes, as per the Canadian convention, are also provided. Risks Significant Investment Risks The investment to which this report relates carries various risks, which are reflected in our Overall Risk Rating. We consider the following to be the most significant of these investment risks: Gran Tierra’s primary producing operations are in the Putumayo Basin of Colombia. In the past the FARC have attacked the primary pipeline in the area (OTA), which has in some cases resulted in the Company having to shut in production for varying periods. To mitigate the exposure, partners in the pipeline have recently expanded the storage capacity at the pipeline terminus. In addition, Gran Tierra has now been able to contract trucks on an asneeded basis (previously only available on a firm basis) which, while more expensive than transporting oil on a pipeline, will allow the Company to continue producing and not have to shut in due to storage capacity constraints. Our Risk Profile Parameters ratings and Overall Risk Rating are set out on the cover page and are explained in our Rating Structure section under “Overall Risk Rating” and “Risk Profile Parameters”. These ratings are an integral part of our Report. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 3 Gran Tierra Energy Inc.

Given the Company’s strong balance sheet and asset base (nil to nominal decline against the existing producing assets through 2014), and the Bretana discovery (which will take time to more fully evaluate and bring on production, but is already considered a material commercial discovery by the Company) the 2P Identified Exploration NAV of $9.17, and the Risked NAV of $9.77 (which includes a higher risked upside for Bretana, but we note not fully valued pending the results of the long term production test and development plans), as detailed in the table below, present a more realistic picture of the value of the Company. We would also point out that historically the Company has successfully converted the possible reserves (i.e. included in the 3P total) to 2P providing support to a valuation above the 2P amounts in a ‘more friendly’ investment climate for international E&P companies. The 3P Identified Exploration NAV is $12.21 per outstanding share. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 4 Gran Tierra Energy Inc.

The fact that the majority of the Company’s production base is not located in the Llanos Basin, which tend to be smaller reservoirs than in the Putumayo, has resulted in the Company’s RLI being better than other Colombian producers, currently at 8.2 years. Gran Tierra has historically maintained a very conservative balance sheet, essentially not carrying any debt and having a substantial working capital position comprised largely of cash, again providing it with a material advantage to its peer group. This financial flexibility will allow the Company to finance the early stage development at Bretana without having to dilute, in the early stages, its working interest position in this very large discovery. Given the Gran Tierra’s comparatively stronger balance sheet and producing asset base, combined with the upside potential and exposure to an exploration portfolio (including Bretana) that can materially impact the Company, the Company is currently undervalued relative to its peer group.

The Company expects to release a resource/reserve update for the Bretana discovery in Q4/13. Should the Bretana Norte discovery establish reserves in the mid-range of the pre-drill resource estimate it could result in an almost 50% increase in the Company’s reserves.

(GTE-T) 6/10/13 Bretana Discovery – Commercial Today, With Upside as Work Continues Gran Tierra – Bretana Norte Drilling Location, Block 95, Peru Source: Gran Tierra Bretana is a material discovery for Gran Tierra, potentially more than doubling the Company’s reserves pending the outcome of planned production tests and appraisal drilling. Given this potential we have, in this report, provided a detailed review of the discovery and the potential it holds for the Company. In summary, the Bretana highlights detailed in this report and potential impact to Gran Tierra include: Test results from the vertical well yielded 1,994 bbls/day of 18.5° API oil; from the follow up sidetrack, 3,095 bbls/day, both with a 0% water cut. A long term production test (at least six months) is planned for early 2014 and the first appraisal well in late 2014. The Company has stated that based on the data to date the Bretana discovery is commercial. The oil already meets pipeline specifications. The Company believes the Bretana discovery is potentially at the high end of the June 2012 resource estimate which was: 1C – 11.5 mmbbls; 2C - 31.6 mmbbls; 3C - 88.1 mmbbls. The mid case (2C) represents 43% of the YE12 2P booked reserves, and the high case (3C) 121%. An early production scenario for Bretana would see the 2014 long term test produce 2,500 to 3,000 bbls/day; a test of the appraisal well would follow in 2015; first production of approximately 10,000 bbls/day would commence in H2/17 and Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 7 Gran Tierra Energy Inc. (GTE-T) 6/10/13 sustainable (five to six years) peak production of 40,000 bbls/day would commence in 2020. Under this scenario the field would produce approximately 100 mmbbls in the ten years following first production. While the crude is 18.5° API, the netbacks would be $51 to $55 per bbl assuming Brent of $100. 10,000 bbls/day would add, on a proforma basis for illustrative purposes, 50% to our 2014F CFPS, and at 40,000 bbls/day, 185%. Even after tax (which wouldn’t initially be the case given the capital expenditures) the increase would be 35% and 130%, respectively. The Company has several marketing options, including barging using double hulled barges, and tieing into the existing pipeline system. At March 31, 2013 Gran Tierra had cash of $236 million and an undrawn $100 million bank line. These funds, plus continued cash flow, will support the Company’s Bretana development plans through 2014 as well as the capital budget for other assets. We estimate full development could cost up to $1.5 billion. The Company would likely be able to fund a large portion of this development with debt after a reserve report is available. Alternatively, the Company may choose to farmout a portion of its interest following the generation of the reserve report, or potentially after the long term production test. There remain other significant prospects on Block 95, including Lead C, which could be larger than Bretana. In addition, while in the early exploration stages, the potential on Blocks 123 and 129 immediately northwest of Block 95 has been partially derisked in the immediate area of the block by third party drilling and on a trend basis by the Bretana success and existing success and production in Ecuador.

(GTE-T) 6/10/13 Bretana Discovery Impactful With 100% Ownership Two Step Acquisition of 100% WI of Block 95 Gran Tierra has a 100% WI in Block 95 located in the Maranon Basin of north-eastern Peru. In December 2010 Gran Tierra farmed into Global Energy Development PLC to earn a 60% WI and assumed operatorship by paying 100% of the costs of an exploration well to a maximum of $15 million and $2 million with respect to costs incurred to that time. In June 2012 the Company acquired the remaining 40% WI from Global for $5.4 million to hold 100% WI. Block 95 covers an area of 1.27 million acres. The block was in force majeure until December 2012 due to delays in receiving environmental approvals. The third exploration phase was extended to June 27, 2013 and the commitments for this phase were completed by the drilling of the Bretana Norte exploration well. Gran Tierra is currently in the fourth of six exploration phases. Gran Tierra – Maranon Basin, Peru Blocks and Bretana Detail (Block 95) Source: Gran Tierra & Haywood Securities Prior to Gran Tierra’s Bretana Norte well, seven wells had been drilled on the block, three of which encountered oil. The 1974 Amoco Bretana 1 (Bretana 10-16-1X) well was considered a discovery. It is located on the northern portion of the structure (and the block) and flowed 807 bbls/day (no pump) from the Vivian formation during a six hour test. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 10 Gran Tierra Energy Inc. (GTE-T) 6/10/13 Gran Tierra – Block 95 Drilling Activity Source: Perupetro and Haywood Securities The Bretana Norte Success Gran Tierra spudded the Bretana Norte 95-2-1XD well December 15, 2012, which reached TD of 10,844 feet MD (measured depth) or 10,284 TVD (true vertical depth) on January 24, 2013. The well discovered 18.5° API oil in the target Vivian formation. Based on logs and other sampling the Company identified an oil bearing sandstone reservoir in the target Vivian formation commencing at 9,408 feet MD, or 8,851 feet TVD. A gross oil column 99 feet thick, with net oil pay of 53 feet, was identified. Data available from the original 1974 well was inconclusive with respect to the oil quality, with a potential range of between 13.1° API and 17.6° API based on various original data sources. A discovery at the high end of this potential range would be commercial, but at the low end would likely not have been. With the test yielding an oil quality above the potential range, plus other data on both the reservoir quality and oil characteristics coming in better than the pre-drill expectations, the Bretana Norte discovery is commercial, and in fact a material, discovery. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 11 Gran Tierra Energy Inc. (GTE-T) 6/10/13 While drilling Bretana Norte Gran Tierra recovered 119 feet of core. The core was oil saturated over most of the identified oil column, plus it extended into the underlying water column. In association with the logs and testing data (below) the Company has a high comfort level that Bretana is a very large discovery. Test of Vertical Well Bore Yields 1,984 bbls/day In February 2013 two short term tests were conducted on a 29 foot interval of the Vivian formation in the vertical well. Test 1: A DST of a 29 foot interval flowed 1,170 bbls/day (19.65 hours; 46/64-inch choke) with a 0% water cut. Test 2: A second shorter test flowed 1,984 bbls/day (1.5 hours; 64/64 inch choke), also with a 0% water cut. Testing was suspended once the onsite storage capacity was reached, however the oil flow rate was increasing when the test was discontinued. It speaks to Gran Tierra’s environmental stewardship that despite having regulatory approval to flare/burn the test oil the Company chose to limit its testing to the onsite storage capacity. The oil characteristics and reservoir qualities identified suggest that the recovery factor from this field could be robust, likely 25% to 30%, and could potentially reach 50% due to the active water drive.

In May 2013 two short term tests were completed over the length of the horizontal sidetrack which had penetrated 25 vertical feet near the top of the Vivian formation. Based on logs, net pay of 1,283 feet in the sidetrack, and average porosity of 22.8%, has been identified between 10,735 and 12,262 feet MD. Test 1: using a 32/64 inch choke, a final rate of 1,699 bbls/day of oil with a 0% water cut was achieved. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 12 Gran Tierra Energy Inc. (GTE-T) 6/10/13 Test 2: using a 64/64 inch choke, the well flowed 3,095 bbls/day with a 0% water cut. Again, the test period was limited to the onsite oil storage capability. We were not expecting test rates to vary materially from those in the vertical well tests as the purpose of this test was to gain additional reservoir quality data that will aid in designing a development program. It is likely there was damage to the wellbore due to the previous drilling and testing activity, which would have negatively impacted the test results.

This test will be conducted over a period of six months at rates estimated to range between 2,500 and 3,000 bbls/day. The test could extend longer provided associated water production remains low as the Company would have to store and transport by barge any produced water. As with the short term oil tests, while the Company does have regulatory approval to dispose of produced water in the adjacent Puinahua River it has chosen not to. Produced oil, and water if any, from this test will likely be transported by a double hauled barge to PetroPeru’s refinery at Iquitos. Next Bretana Well in Late 2014 In early May Gran Tierra increased its 2013 capital budget, largely due to the success at Bretana Norte. Included in the increase are the Company’s plans to acquire 382 sq km of high density 2D seismic in Q3/12 over the Bretana structure in order to provide additional data for selecting the next drilling location. The Company is preparing and will file a comprehensive EIA (Environmental Impact Assessment) that will seek blanket approval to conduct seismic, drilling and development operations over the field. The Company will propose three drilling pads, from which it could drill a total of 24 wells. The wells would be drilled directionally, and from these pads all of the potential bottom hole targets can be accessed. The EIA is expected to be approved in H2/14, after which the Company plans to drill its first appraisal well. Using the seismic data, and ultimately drilling data, the Company is attempting to identify the optimum drilling locations along the crest of the anticline (noted by the strike line in the diagram at right below). The well will be drilled directionally from Location 3 targeting a bottom hole location in the bright spot to the south. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 13 Gran Tierra Energy Inc. (GTE-T) 6/10/13 The cost of acquiring the seismic, preparing the drilling location and other field related activity, plus of course drilling the appraisal well, will cost Gran Tierra approximately $100 million. The final drilling cost estimate is dependent on the well design. A long term production test would be conducted on the appraisal well. Assuming the well is successful and the test results support a development, development drilling would commence in 2015. Gran Tierra – Bretana Structure, Block 95, Peru Source: Gran Tierra and Haywood Securities. Based on data obtained from the older Envidia 1 well south of Bretana the oil water contact is believed to be relatively static the length of the structure. If the second well is successful, the reserves assigned to Bretana could increase materially from the existing estimates. Reserves Likely Higher than 2012 Resource Estimate In mid-2012, based on the available seismic and data from the original 1974 Amoco well Bretana 1, GLJ estimated the contingent recoverable resource (pre-drill) at Bretana Norte at: 1C – 11.5 mmbbls; 2C – 31.6 mmbbls; 3C – 88.1 mmbbls. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 14 Gran Tierra Energy Inc. (GTE-T) 6/10/13 The 2C case represents 43% of the Company’s YE12 2P reserves – hence a discovery of this potential would be very material to Gran Tierra. The areal extent of the field is potentially very significant. Gran Tierra’s Bretana Norte and the 1974 Amoco Bretana well are almost 6 km apart. Assuming the field extends to Gran Tierra’s Location 4 (see diagram below) it would be almost 16 km long. Gran Tierra – Bretana Structural Cross Section Source: Gran Tierra and Haywood Securities The reservoir and oil quality encountered in the Bretana Norte well were much better than expected before drilling based on the 1974 Amoco well data. Based on the current analysis of the Bretana Norte data Gran Tierra believes the pre-drill contingent resource estimate to be conservative. The Company has commenced preparation of a pre-FEED engineering study, which will support a development plan and reserve bookings, likely in 2013.

(GTE-T) 6/10/13 Development Scenario Has Several Marketing Options Assuming Gran Tierra proceeds with development of Bretana, development drilling would commence in 2015, first production in 2017 and a five to six year sustained peak reached in 2020. The Company expects that first production of approximately 10,000 bbls/day could commence in H2/17. Additional drilling, and maturing of the transportation options, would result in the field reaching peak production of 40,000 bbls/day by 2020, which could be sustained for five to six years. Under this scenario the field would produce approximately 100 mmbbls in the ten years following first production. Clearly Bretana could be a significant addition to Peru’s total crude production, and depending on the progress of other developments, could be the discovery that moves the country to selfsufficiency, or alternatively, sustains a self-sufficiency peak. As with the Block 67 discovery (see Appendix 2), the Government of Peru may be moved to declare the Bretana discovery of national interest, which may expedite various regulatory approvals for the development of Bretana. While it is premature to determine exactly how produced oil at Bretana would be transported to market, the Company has several options available. Several of these options include: Iquitos Refinery - Oil produced during the long term test period will likely be barged to the PetroPeru refinery at Iquitos. Perenco is also delivering its initial production, before a pipeline is constructed, to the Iquitos refinery (see Appendix 2). The Selva Refinery has current capacity of 10,000 bbls/day, and there is discussion of expanding it to 14,000 bbls/day, although there is not yet a definitive timeline. Currently the refinery is processing 8,000 bbls/day, much of which is currently imported up the Amazon River, through Brazil. Pipeline Only Option - A pipeline from the Bretana field, north approximately 100 km to tie into Pump Station No. 1 on the Northern Pipeline to the coast. This option is the shortest; however the route passes through swampy areas and a national preserve that could result in the cost of laying the pipeline more expensive than other options. Note that a third party would likely build and own the pipeline, not Gran Tierra. Oleoducto Nor Peruano (Northern Peru Pipeline) transports oil from the Maranon Basin to the marine terminal at Bayovar. The total length is 852 km, transporting crude from Andoas to the north (to which Block 67 will be tied in) and San Jose De Saramuro to the east at Station 1 (to which Block 95 could potentially be tied in). The current capacity is 250,000 bbls/day. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 16 Gran Tierra Energy Inc. (GTE-T) 6/10/13 Peru – Oleoducto Nor Peruano Route Source: Barrett Resources and Haywood Securities Combination Pipeline/Barge Option - A pipeline would be built south from Bretana to the Ucayali River, approximately 200 km, and from there barged to Pump Station No. 1. This route cuts the required barge traffic in half compared to the option below, and greatly reduces the environmental exposure. Barge Only Option - Barge all of the oil to Pump Station No. 1. While physically possible, at 40,000 bbls/day this would result in a significant increase in barge traffic on the river (the rivers of the Amazon area are the highways and transportation of most goods occurs on the river system). In addition, the risk of an oil leak or accident increases with more barges on the river. Barging may be acceptable in the early days of production from the field; however we expect the Company would ultimately opt for one of the above pipeline options. Early production will likely be barged to the Petroperu Selva Refinery in Iquitos, including the test oil from the most recent tests. The Bretana oil has a high salt content and will need to be diluted initially in order to meet the refinery specifications. Should volumes increase after testing is complete the Company would wash the oil on location to reduce the salt content, which is a relatively simple and inexpensive process. Current capacity of the refinery is 10,000 bbls/day, but is running at 8,000 bbls/day. There is an intention to expand the capacity to 14,000 bbls/day, although these plans are not definitive.

(GTE-T) 6/10/13 Petroperu – Selva Refinery, Iquitos Source: Haywood Securities There is a barge construction facility on the Amazon River in Iquitos, called SIMA, which is a state owned facility that also constructs barges for the private sector and vessels for the navy, as required. A barge capable of transporting 8,000 bbls (which would be the limit due to the river flow rates) would take approximately four months to construct. The facility is capable of building six barges a year. Should Gran Tierra pursue the barge option additional barges could be constructed lower on the Amazon River in Brazil where other similar companies are located.

However, based on the price received for other similar crudes in Peru, and the royalty structure, we can provide a reasonable expectation. Crude in Peru is priced at a discount to Brent, depending on the oil quality. Based on the price received for other crude produced in Peru that is 18° API Bretana crude would likely receive Brent less 18% to 20%. The royalty rate in Peru is quite attractive. As set out in the table below, up to 5,000 bbls/day the royalty rate is 5%, increasing on a sliding scale basis to 20% when production reaches 100,000 bbls/day, and 20% for production above this level. At 10,000 bbls/day Bretana would attract a royalty of 5.8%, and at 40,000 bbls/day 10.5%. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 19 Gran Tierra Energy Inc.

Assuming all oil is barged; the cost would be $12 to $15 per bbl and lower with a pipeline option. Operating costs of $10 per bbl would not be unreasonable, but still quite early to estimate. Based on the above assumption, at the first commercial production level of 10,000 bbls/day Bretana oil would generate a netback of $55.08 per bbl. At the sustainable peak rate of 40,000 bbls/day the operating netback would be $51.05 per bbl. The 40,000 bbls/day scenario results in a netback only 11% below the forecast 2014 corporate netback of $57.48. Peak Production Would Increase Proforma 2014 Cash flow 185% The impact to the Company’s cash flow would be material (in comparison to our 2014 forecast, to provide a reference point). Even the initial commercial production level of 10,000 bbls/day would increase cash flow 50%. A 40,000 bbls/day project would almost triple CFPS, increasing it 185%. The income tax rate in Peru is 30%. There is also a tax stability guarantee in the contract that ensures that the tax rate will not change from the rate in force at the time the contract was granted. Assuming there were no capital pool deductions, the most conservative view, the after tax impact would continue to be material with 10,000 bbls/day increasing cash flow 35%; and 40,000 bbls/day adding 130% to the Company’s after tax cash flow.

Our preliminary estimate of the cost of full field development could ultimately be $1.2 to $1.5 billion. Gran Tierra currently has cash of $236 million and an undrawn bank line of $100 million. Certainly the planned activity through 2014 can be internally funded by the Company from the above noted, plus cash flow generated over this period. The Company may choose to farmout a portion of its interest to mitigate the financial risk. We expect there would be interested parties for such an offer, especially given that there are other material prospects on the block, however such a transaction may not occur prior to the end of the extended production test on Bretana Norte. A discovery such as Bretana would, after appraisal drilling, support a higher line of credit should the Company opt for that option. Repayment could be achieved within two to three years of peak production. However, the Company has previously maintained a very conservative approach with respect to incurring debt (having said this, the Bretana discovery is an above average opportunity). Block 95 Holds Other Exploration Potential Several other large leads have been identified on Block 95, two of which have been firmed up. Pursuing these opportunities is of course longer term, but could be drilled before Bretana production moves to peak levels. The prospects are both very large, with Lead C having the potential to exceed Bretana. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 21 Gran Tierra Energy Inc.

The Kanatari 1 exploration well, drilled in Q1/11, did not have oil or gas shows and the reservoir was wet. Both blocks were subsequently abandoned. Block 95 became the next focal area for the Company, which has exploration exposure, in addition to Bretana, that could exceed 100 mmbbls. In addition to Block 95, Gran Tierra now has a 100% WI in Blocks 123 and 129, also in the Maranon Basin located northwest of Block 95, after acquiring its partner’s interests in the blocks in October 2012 (80% in each for a total of $7.1 million). The two blocks cover an area of 2.32 and 1.17 million acres, respectively. The Company is acquiring 567 km of 2D seismic over the two blocks which will complete the work commitments for the current exploration phases. In the Ucayali Basin of south central Peru the Company has a 100% WI in Blocks 107 and 133 which cover an area, respectively, of 0.62 and 0.98 million acres. These blocks were acquired with the 2011 Petrolifera acquisition. Block 107 is in the fourth and final exploration phase, but currently under force majeure. When force majeure ends the Company will apply for a 12 month extension to the exploration period which requires the drilling of one well and 300 units of work. The block is in the second of four exploration phases, however PeruPetro froze this block until June 7, 2013. The Company intends to acquire airborne gravity and magnetic surveys over the block and has requested approval for this to satisfy the specified work commitment of acquiring 150 km of 2D seismic.

(GTE-T) 6/10/13 Subandean Basin Heavy Oil Trend – Exposure Continues Into Peru Source: LACPEC 10 Conference 2010 and Haywood Securities Bretana Reserves/Resource Potential Through two transactions Gran Tierra acquired 100% ownership of Block 95 in the Maranon Basin of Peru. In December 2010 Gran Tierra agreed to farm-in to earn 60% of Global Energy Development PLC’s (which operates under the name Harken in South America) 100% interest in Block 95. To earn its interest Gran Tierra assumed the drilling cost of an exploration well, to a cap of $15.0 million, as well as its share of past costs incurred with respect to the well. Costs were to be split on a pro-rata basis after reaching the $15.0 million cap. At the time the well was expected to be drilled by the end of 2011. In June 2012 Gran Tierra announced that it had acquired the remaining 40% WI in Block 95 from Harken to own 100% of the block. In January 2013 the regulator approved the second acquisition by Gran Tierra. The original contract for Block 95 was executed in April 2005. Harken Reserves Estimate for Bretana At YE11 Harken’s independent engineers, Ralph E. Davis Associates Inc. out of Houston, Texas prepared a reserves report for the Bretana discovery under both a Canadian (NI 51-101; constant and forecast pricing) and UK basis. While the assumptions and methodology are undoubtedly different than if Gran Tierra’s independent engineers, GLJ, had prepared the estimate, the results do provide an example of the order of magnitude that the Bretana discovery could have to Gran Tierra. Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 24 Gran Tierra Energy Inc. (GTE-T) 6/10/13 The reserves estimates assumed, on a 100% basis, the following: Total Proved Undeveloped reserves of 12.5 mmbbls; Total 2P Undeveloped reserves of 22.1 mmbbls; and Total 3P Undeveloped reserves of 67.2 mmbbls. Under the Canadian disclosure format the constant oil price assumed was $89.38 per bbl (net after royalty), and the forecast oil price average for the first ten years was $87.88. The UK disclosure format assumed a higher forecast oil price, averaging $112.91 in the first ten years of the forecast. Under the Canadian based forecasts the NPV20 (using a 20% discount rate) of the 2P reserves was $501 million under the constant price case and $436 million under the forecast price case – equivalent to $1.78 and $1.54 per share, respectively. The NPV15 values were $623 and $542 million, respectively, equivalent to $2.21 and $1.92, respectively. Global Energy (Harken) – Bretana Reserves Estimate YE11 Independent Engineers: Ralph E.

(GTE-T) 6/10/13 Peru – Country Backgrounder Oil and Gas Business Peru could be characterized as ten years behind Colombia as far as level of oil and gas drilling activity and infrastructure in place. The other side of the coin is that as there has been less exploration drilling there remains the potential for very large discoveries yet to be made. This is the basis for Gran Tierra’s involvement in the country, which we have characterized above as its ‘elephant hunting’ territory. The Bretana discovery, which following appraisal drilling has the potential to be as large as 100 mmbbls, plus the other prospects on this block alone provide support for this argument. In 2012 there were only 13 exploration wells drilled in Peru, down from 15 in 2011. Prior to 2011 between 5 and 8 exploration wells had been drilled in each of the prior 7 years, and fewer prior to 2004.

Crude oil production has declined year over year in all but two of the last ten years. Over the next few years the country is counting on development of the Block 67 oil discoveries (see Appendix 2) and planned growth from other discoveries in the Maranon Basin to move it up to a self sufficient position and eliminate the need for importing crude. The Bretana discovery on Block 95 provides Peru with an opportunity to maintain self sufficiency, which could otherwise potentially be threatened in the next decade.

The development area expands over two blocks, Block 88 (booked reserves of 10 tcf) and Block 56 (2.3 tcf). Pluspetrol is the operator and partners include Hunt Oil SK Energy and Repsol among others. Current production from the two blocks is approximately 1.1 bcf/day and 102 mbbls/day of liquids. In 2010 Netherland Sewell estimated, on a best case basis, that the field had 15.9 tcf of recoverable resource (range of 11.2 to 18.6 tcf). In June 2010 Peru commissioned South America’s first LNG facility at Pampa Melchorita, Alan Knowles, CFA, CMA403-509-1931aknowles@haywood.com Page 26 Gran Tierra Energy Inc. (GTE-T) 6/10/13 which sources Camisea gas. The facility’s capacity is 4.4 million tonnes per year. Also in 2010 Peru signed an agreement to supply Mexico with 4 tcf of natural gas over the next 18 years. Canada and Peru Next to Mexico, Peru is Canada’s second largest bilateral trading partner in Latin America (including the Caribbean). Canada and Peru signed a free trade agreement in 2009. In 2011 Canada imported $4.5 billion of goods from Peru (primarily precious metals and mineral ores) and Canadian exports to Peru were $0.5 billion (cereals, machinery, paper). The Canadian International Development Agency (CIDA) has been involved in programs in Peru since 1968. In late May 2013 Prime Minister Harper, International Trade Minister Ed Fast, and five senior Canadian business executives (including Dana Coffield, President of Gran Tierra, and representatives of mining and agriculture) completed a business development trip to Peru. During his trip Harper announced a five year, $53 million aid package for the country (in the form of CIDA projects) to support development initiatives, including: Improving environmental management of mining and energy activities in Peru. Promoting competitiveness and economic diversification in Peru’s extractive regions. Strengthening natural resource management in key regions of Peru. Strengthening management of the education sector in Peru. Both countries are members of the Trans-Pacific Partnership (11 members; a meeting was held in Lima in May 2013) and Organization of American States, and Canada is currently has observer status, but is approved to become a member, of the Pacific Alliance (four members – Chile, Colombia, Mexico, Peru; a meeting was held during Harper’s visit in Colombia in May 2013).

(GTE-T) 6/10/13 Appendix 2: The Block 67, a Heavy Oil Development Example Block 67 is located in the northern portion of the Maranon Basin, in the Amazon drainage south of the Ecuador border. The discoveries on Peru’s Block 67 extend the heavy oil trend from the giant Ecuadorean ITT complex (Ishpingo, Tambococha, Tiputini) and other Ecuadorean discoveries. Three discoveries drilled in 1998 by Barrett Resources, Dorado (71 feet of oil pay; 14 to 16° API; Pirana (84 ft of oil pay; 12 to 21° API; and Paiche (179 feet of oil pay; 12 to 13° API), were the basis for the Block 67 development. The oil price at the time meant these heavy oil discoveries were not commercial. In 2006, with higher oil prices, Barrett drilled delineation wells at Dorado and Paiche. The company commenced preparing a comprehensive development program after these wells were drilled. Wells were drilled to between 7,000 and 7,500 feet and tested oil from the Basal Tena, Vivian and Basal Chonta formations. In January 2008 Perenco acquired 100% of Block 67 from Barrett. The Plan of Development, approved in July 2007 prior to Perenco’s acquisition, contemplated first oil in January 2011; a $1.5 billion development cost and the potential for peak production levels of 100,000 bbls/day. Prior to the acquisition of Block 67 by Perenco, Barrett had estimated the 2P contingent resource at 346.8 mmbbls (Paiche being the largest at 198.4 mmbbls) and the 3P resource at 804.0 mmbbls (Paiche at 426.9 mmbbls). Netherland Sewell prepared the contingent resource estimates. In 2009 the government of President Alan Garcia passed a statute declaring the Block 67 development to be of national interest. In June 2009 the EIA approving the drilling of 14 delineation wells from seven platforms, which at the time was estimated to cost $185 million. Total investment on the block was at this time estimated to be $2.0 billion. In August 2012 the regulator approved the Block 67 EIA with respect to development, which had been submitted earlier in the year. Development contemplates drilling up to 200 wells, including 15 water injection wells, from 18 platforms. First production of 7,000 bbls/day is expected before the end of 2013, which will be transported by barge to Petroperu’s refinery at Iquitos. A 270 km pipeline will be constructed from Block 67 to Anodas Station, the current northern terminus of the North Peuvian Pipeline. Commencing in 2017 production of 60,000 bbls/day will be transported by pipeline to the port of Bayovar. Diluent, which is shipped from the coast to Andoas by a separate 12 inch pipeline, will be added to blend the Block 67 heavy crude to the required 18° API pipeline specification.
