SECTION 3
GENERAL CONDITIONS
I | INDEPENDENT CONTRACTOR |
| The general scope and practice of the Services shall be under the direction of Company, but the actual conduct and the manner of performance of the Services shall be under the direction, supervision and control of Contractor. Contractor is an independent contractor, and is not an agent of Company, and persons engaged by Contractor in the Services and all matters incidental thereto shall be employees or independent subcontractors of Contractor and not of Company. No employee of Company shall be deemed to be an employee of Contractor, and neither Company nor Contractor shall have control over the employees of the other. |
II | REPRESENTATIVES |
2.1 | Company and Contractor shall each appoint and maintain a competent representative to act on its behalf. The representative shall be authorised to act on behalf of Company and Contractor respectively in all matters concerning the Services and administration of this Agreement. Representatives shall be available for consultation at all reasonable times, and all oral/or written communication shall be between these representatives. Should a Party's representative prejudice the proper and efficient performance of the Services, the other Party may request his removal and upon good cause shown, the representative shall be removed and replaced as soon as is reasonably practicable. Contractor reserves the right not to allow employees of its competitors or its former employees or former employees of its affiliates to act as Company Representatives. |
2.2 | Company may designate one on-board representative (“the On-Board Representative”) to act on its behalf and to supervise and where necessary give directions about the Survey. Such representative should be entitled to exercise Company's rights arising from this Agreement. All costs and expenses of and incurred by such representative shall be met by Company, save that Contractor shall provide accommodation and food for such representative. |
III | INGRESS/EGRESS AND PERMITS/LICENSES |
3.1 | For Services rendered off Contractor’s premises, Company shall secure for Contractor rights of ingress and egress to the area where Services are to be performed by Contractor. Company shall advise Contractor of any limitations or restrictions affecting ingress and egress, and Contractor shall abide by such limitations or restrictions.

During such period Contractor shall be paid in accordance with the rates, charges and fees set out in Appendix D. |
7
HDY BOS Contract Sept 29, 2009 2D Seismic Service Agreement
3.2 | Contractor shall be responsible for obtaining all licenses and approvals required by applicable law from any authority to enable Contractor to perform the Services. This does not include permits to be provided by Company pursuant to 3.3 below. |
3.3 | Company shall be responsible for obtaining all licenses, permits and approvals, required in the name of Company, from any authority or company to enable the Services to be performed. For the avoidance of doubt this shall include any license being in the nature of a mineral exploration or prospecting license. Contractor acknowledges Company’s exclusive contract with the Republic of Guinea and Company represents to Contractor such exclusive rights and Company has shown Contractor its rights are granted through its 2006 Hydrocarbon Production Sharing Contract, and as such, Company is the lessee and owner of the concession offshore Guinea and thus Company may notify the Guinea government of any of all of its petroleum operations and any and all of its chosen sub-contractors, and therefore Company’s arrangement with the government is to merely notify the government of its sub-contractors and ongoing work, and as such Company will be providing Contractor with permits it writes in accordance with its exclusive contract with the Republic of Guinea for performing all work specified in Work Orders associated with this agreement, and such permits, may or may not come with timely independent acknowledgement from the Republic of Guinea and the parties agree that any such lack of acknowledgment will not be cause to delay any Services under this agreement. In the Company’s experience the Government usually responds in writing upon acknowledgement requests but not always, thus the 2006 Production Sharing Contract is the basis for it or any of its Sub-Contractors to enter the contract area to perform petroleum operations under the 2006 Production Sharing Contract which is in full compliance with the 1986 Petroleum code of the Republic of Guinea. |
3.4 | Subject to the provisions of Clause 13, Company shall indemnify the Contractor against any liability whatsoever arising from its failure to obtain and maintain, or any breach of, any license, permit or approval which it is responsible for obtaining under 3.2 and 3.3 above. |
IV | WARRANTIES |
4.1 | Contractor warrants that the Services will be performed in accordance with good geophysical practices and with all the requirements of this Agreement and will at the time of performance comply with the technical and other specifications contained in this Agreement. Any interpretation of seismic data, interpretation of test and any recommendation or reservoir description is expressly excluded from the scope of the Services. All other warranties, express or implied, or whether relating to merchantability, fitness for a particular purpose, or otherwise, are hereby excluded and disclaimed. |
4.2 | Contractor does not warrant the accuracy of seismic data transmitted by electronic processes and will not be responsible for any liability resulting from breach of the integrity of the data, including any accidental or international interception of such data by others. |
8
HDY BOS Contract Sept 29, 2009 2D Seismic Service Agreement
4.3 | As long as the data is delivered periodically and can be verified by Company every week or two weeks during the data acquisition, the Parties acknowledge that defective, damaged or incorrect data delivered to Company will become apparent during the course of the Services. Contractor shall not be liable for any claims submitted in respect of such data after demobilisation as long as Company has received all the source data field records and verified and backed up the source data. |
V | SEISMIC DATA |
5.1 | Until all raw data field records and tapes in SegD format and P190 navigation files, and all other raw field records are delivered to the Company and verified by the Company , Contractor remains responsible for the integrity protection and security of all seismic data. No data shall be erased from Contractor’s acquisition and storage media onboard the acquisition vessel until field tapes have been received and verified by Company, and the Company notifies Contractor.. If in the provision of the Services, Contractor loses, damages or destroys Company's seismic data tapes (which are in Contractor's custody and control), Contractor shall bear the risk of and shall defend, indemnify and hold Company harmless against the loss, damage or destruction of such tapes. Company's remedy and Contractor's liability under this Clause 5.1 shall be limited to one of the following at Contractor’s option: |
| a) | refund to Company of that portion of the seismic data acquisition costs originally incurred, that is directly related to and required as a result of the loss, damage or destruction of the tapes; or |
| b) | re-acquisition by Contractor of the seismic data lost, damaged or destroyed, at a time to be determined by Contractor, but within 12 months from the date of such loss, damage or destruction. |
| However, if the damage is such that it may be reasonably corrected through the provision of tape copies or further re-processing services, that shall be the sole remedy available to Company. Notwithstanding the above, if a reputable or agreed common carrier is used to transport the seismic data tapes, then Company shall bear the risk of loss, damage or destruction of the tapes during such transport and Contractor shall bear no liability therefore. However, until data is obtained from Contractor and verified, Contractor is not deemed to have delivered the data. In all cases damaged tapes that are replaced by Contractor shall become the property of Company. |
5.2 | Unless specifically and separately contracted and paid for, Contractor assumes no liability for and shall not be responsible for any gratuitous bailment or storage of any seismic data, whether on tape, disk, in physical sections, in computer memory or in any other form whatsoever, Contractor shall not be liable for any damage, destruction, loss or theft of any such seismic data or portions thereof and Company agrees to defend, indemnify and hold Contractor harmless from any and all claims brought by third parties in relation to such seismic data. |

5.3 | Contractor shall not be required (save as otherwise expressly agreed in writing) to store, hold or save any drawings, seismic data, tapes, reports, records or other information in any media about or arising from the Services after completion of the Services. |
VI | TITLE |
| All drawings, reports, records, seismic data, tapes and other documents or information furnished by Contractor in the course of, or as a result of, performing the Services may be used by Company for any lawful purpose and shall be and become the property of Company as soon as they are created, subject only to Contractor’s receipt of the full payment for the Services rendered. |
VII | CONFIDENTIALITY |
7.1 | All information in any media supplied by Company and all material to which Company becomes entitled under Clause 6 shall be and remain the property of Company and shall be returned by Contractor to Company immediately upon completion or termination of the Services, upon request in writing.

Excepted from this undertaking is any information or media already in the public domain or which is required to be disclosed by law or legal process. |
7.2 | Company shall treat in the strictest confidence all specifications, know-how, technical and other information about the techniques, services and equipment used or provided by Contractor under this Agreement and otherwise concerning Contractor or its operation and shall not disclose nor allow to be disclosed the same to any third party without the prior written consent of Contractor. Company warrants that its personnel are aware of and shall comply with the provisions of this sub-clause 7.2. Excepted from this undertaking is any information or media already in the public domain or which is required to be disclosed by law or legal process. |

X | COMMON STOCK ISSUED TO CONTRACTOR FOR DEPOSIT AND TO FACILITATE ADDITIONAL PAYMENT OPTIONS |
Regarding the Contractor’s ownership of the common stock of Company’s parent Company, Hyperdynamics Corporation, as prescribed hereunder, the Contractor shall not of its own volition cause itself or its affiliates (as the term “affiliates” is defined in U.S. law) to beneficially own, in the aggregate, more than 4.99% of the outstanding common stock of Hyperdynamics Corporation until six months after this Agreement has been fully performed by the Contractor. The Contractor understands that Hyperdynamics Corporation is a public company. The Contractor is aware that the work of the Contractor may expose the Contractor to inside information about Hyperdynamics Corporation and its affiliates. The Contractor understands that buying or selling securities while having knowledge of inside information is unlawful. The Contractor understands that tipping others about inside information is unlawful.
The Contractor and Company agree to the following deposit in the form of common stock and related administration and payment options:
| 10.1 | A deposit for this Agreement of 2,500,000 shares of common stock , currently representing approximately 4.4% of the outstanding shares of Hyperdynamics Corporation’s unregistered restricted common stock, listed with the American Stock Exchange (AMEX Symbol: HDY - herein referred to as “Deposit Shares” or “Deposit Stock”) with an agreed value of $4,075,000 shall be made by the Company’s parent company Hyperdynamics Corporation. SCS Corporation is a wholly owned subsidiary of Hyperdynamics Corporation. For the purposes of the rest of this article of the Agreement, Company means collectively both Hyperdynamics Corporation and SCS Corporation. This deposit shall act as collateral for the remaining mobilization payment of $1,100,000 due within 8 weeks of the initial payment of $500,000. If the Company does not timely pay this remaining mobilization fee, the Contractor may begin to sell the Deposit Shares to satisfy the remaining mobilization fee. |
| 10.2 | To issue the Deposit Shares, restricted common stock certificates with restrictive legend will be issued to and in the name of Bergen Oil Field Services AS (Contractor) within 30 days of signing of contract and after the stock has been listed on the American Stock Exchange (AMEX) with a Listing of Additional Shares (LAS) application being approved by the AMEX. These Deposit Shares will be delivered to Contractor and at their specific direction for international delivery service such as DHL or Federal Express. |
| 10.3 | Upon the six month anniversary of issuance of the Deposit Stock, should it remain issued and outstanding, the Deposit Stock will be deposited into an electronic stock trading account (the “Deposit Account”) with C.K. Cooper or other mutually agreed registered FINRA broker dealer, registered and licensed in the United States. The broker dealer receiving the shares for deposit will be referred to herein as the “Deposit Manager”. Once the Deposit Account is established and the Deposit Shares deposited, the Deposit Manager will be immediately instructed by Contractor to begin selling the Deposit Shares in accordance with SEC regulations for 144 restricted stock sales and such Deposit Manager will be instructed by Contractor to sell only a specified maximum number of shares on any one trading day calculated as follows: |
12
HDY BOS Contract Sept 29, 2009 2D Seismic Service Agreement
| Total average trading volume per day for the prior 90 days as calculated and reported by Yahoo Financial’s website, multiplied by 5%. Thus, as an example: On any particular trading day, presuming the reported average daily trading volume for the last 90 days as reported by Yahoo Financial is 300,000 shares, then the maximum shares eligible to be sold on that particular trading day is (300,000 x 5%) 15,000 shares. |
| 10.4 | The Deposit Manager will be obligated, by the specific instruction of the Contractor, to send daily trading records, sales details, and balances of the Deposit Stock and any cash balances from the proceeds of the sale of Deposit Shares to Company, at the close of each business day via email to Hyperdynamics Corporation as follows: ***@***. The Contractor may optionally arrange for a view and report only login ability for the Company to view all the activity in the Deposit Account. |
| 10.5 | The Contractor may at any time move cash sales proceeds realized from the sale of Deposit Shares (herein referred to as the “Cash Proceeds” or “proceeds”) into any other account of Contractor, but immediately upon doing so, Contractor must notify Company with a memo via email that specifies which outstanding invoices that Contractor is applying such Cash Proceeds to. Such application of proceeds must be made to the oldest outstanding invoice(s) first. No Cash Proceeds shall be moved by Contractor from Deposit Account unless there are legitimate outstanding invoice(s) to apply such proceeds to. |
| 10.6 | On the due date of any outstanding invoice(s) due to Contractor by Company under this Agreement, Company may elect to do the following to pay for such legitimate and undisputed outstanding invoice(s): |
| a. | Pay outstanding invoice(s) in their entirety in cash by wire transfer; or |
| b. | Pay any portion of the outstanding invoice(s) with Cash Proceeds available in the Contractor’s Deposit Account that have already cleared with the Cash Proceeds deposited after the prior sale of Deposit Stock. This form of payment will be referred to herein as an “Applied Cash Proceeds” payment. In such case the Company will email a memo to the Contractor of how much of the cash in the Deposit Account is to be applied to which invoice(s) that become due. Such amount designated will be considered the “Applied Cash Proceeds” to pay all or parts of such outstanding and due invoice(s). It will be the sole responsibility of the Contractor to move such Applied Cash Proceeds out of the Deposit Account to its other cash accounts. Any remaining balance of cash required to pay off the invoice(s) that are due must be paid by Company by cash wire transfer as provided for herein within the agreed upon terms. |
13
HDY BOS Contract Sept 29, 2009 2D Seismic Service Agreement
| 10.7 | Once the Deposit Manager begins selling the Deposit Shares, the Company at any time prior to all of the Deposit Shares being sold, notice the Contractor by email and redeem any Deposit Shares remaining unsold in the Deposit Account, for a price of $6 per share, by wiring the appropriate amount to the Deposit Account. In such case the shares will be transferred to the Company immediately by electronic transfer (DTC) and no more Deposit Shares may be sold. |
| 10.8 | Also after the Deposit Manager has begun selling the shares, and at any time there are no more invoice balances outstanding that were generated from the 3-D survey and processing work associated with this Agreement, then no more Deposit Shares will be sold by Contractor and Contractor will instruct Deposit Manager not to sell any more Deposit Shares. At such time as the parties agree that all obligations under the Agreement have been fulfilled, then any remaining unapplied Sales Proceeds and Deposit Shares, at the option of the Company, will be refunded directly to the Company and the Deposit Account closed. |
| However, if the Company agrees and approves, upon request of Contractor to Company, then any remaining unapplied Sales Proceeds may be applied as Company’s credit towards future work with the Contractor. Also upon the Company’s agreement and approval, any remaining Deposit Shares may be sold by Contractor, or at Contractors risk held by Contractor. In this case, if the stock is sold, the net Sales Proceeds amount from the sale of the remaining Deposit Stock shall be credited by Contractor to Company’s account to be available to pay for future services. |
| Should the Contractor decide (the “Decision”) not to sell the Deposit Stock, then Company shall receive a credit against future work based on the number of Deposit Shares remaining times the closing last sales price reported by the AMEX on the date of the Decision. In this case, as approved by the Company, the remaining Deposit Shares would remain as an asset owned by Contractor with no further encumbrances and the risk of loss in the future on such remaining Deposit Shares shall be born entirely by Contractor. |
EXAMPLE:
On the date of the Decision when there are no more unpaid Company obligations to Contractor under this Agreement, and if there was 500,000 Deposit Shares remaining on January 31, 2009 in the Deposit Account together with $100,000 and Contractor and Company agreed that 100% of the obligations had been met by the Company, and the Company agreed to take a credit opposed to a refund, and the last trade price of Hyperdynamics stock was $7 per share; then the Company would receive a credit for ($100,000 + ($7x500,000) $3,600,000 to be applied against future invoices for future work. If the Contractor decided to not sell the stock remaining, still under the required selling limitation, then upon notice of Contractors intent to keep the Deposit Stock, a credit of $3,600,000 would be issued by Contractor to Company for future work and if the stock was sold for $20 in the future, Contractor would receive $10,000,000 (500,000 x $20) and all proceeds would belong to Contractor. If the same stock sold for $5 then Company would still have a credit on the books for $3,500,000 for stock that Contractor sold for $2,500,000.

45
HDY BOS Contract Sept 29, 2009 2D Seismic Service Agreement
Shot Point Numbering
The shot point positions and numbers of the pre-plotted lines shall correspond to the near trace CMP positions (mid-point between the centre of the source array and the centre of the nearest receiver group).
Start and end of line
The start and end of the pre-plotted lines shall correspond to the full-fold limit. The first shot point of a sail line shall therefore be fired when the position of the corresponding near trace CMP coincides with the pre-plotted start of line to ensure the required coverage within the full-fold limit.
The guns shall however be fired for at least 10 shots prior to start of line or segment of line to synchronise the guns and initiate the navigation filters.
Run-in
The length of run-in shall be sufficient to ensure that the streamer is straight at the first shot point of a line or line segment whether prime or reshoot.
A minimum of one and a half streamer length as run-in is required for the start of each line in order to straighten and stabilise the streamer (i.e. the vessel shall be on the pre plotted sail line headed for the first shot point at this distance).
Run-out
A run-out corresponding to half a streamer length shall be recorded after the pre-plotted end of the line to ensure the required coverage within the full-fold limit.
Lines recorded in several segments
As far as it is possible, lines shall be recorded in one pass.
In case of a line acquired in several segments, the following rules shall apply:
Direction specification
A segment of 2D line shall not be recorded in the opposite direction to another segment of that line unless very specific conditions are met (obstructions, shallow waters, etc) and only with On-Board Representatives agreement.
Feather matching specification
The streamer feathering of overlapped segments shall not differ by more than 8°.
Minimum length for a segment of line
The minimum acceptable length for a segment of line shall be equal to one cable length, without being less than 5 km (first SP – last SP). No short “ window ” can be recorded or reshot in the middle of a line.
Overlaps
Overlaps between consecutive segments of a line shall be recorded to provide full fold coverage overlap in one CMP.
The shot point overlap between 2 segments recorded in the same direction shall therefore correspond to half a streamer length.
Between 2 segments recorded in converging opposite direction, the shot point overlap shall therefore be twice the “ set back offset ” plus one streamer length.
46
HDY BOS Contract Sept 29, 2009 2D Seismic Service Agreement
Survey acquisition speed
Whilst recording online and changing lines, the vessel speed through the water shall be maintained at a nominal 4.8 knots (with variation between 3.5 knots minimum and 5.5 knots maximum, depending both on the acquisition parameters and the current).
During the straight part of a run-in, the vessel speed through the water shall be the same that during recording online. A variation of 20% is allowed, providing it does not affect the streamer behaviour at the start of line.
CONTRACTOR shall make every endeavour to determine the best combination of propeller pitch and shaft rotation speed (if applicable) in order to minimise the vessel generated noise.
Vessel steering
The vessel shall be steered so that the position of the first near-trace CMP shall not deviate more than 25 m from the pre-plotted line.
Line recording not to commence
Recording of any new line or line segment shall not commence under any of the circumstances defined:
Streamer is not straight or stabilised in depth
There is less than two calibrated depth sensors operational per sub-array
The streamer feathering cannot be computed (either with the tail buoy RGPS position, or with the vessel heading sensors and streamer compasses)

On-Board Seismic QC Processing
The onboard 2D QC seismic processing will be based on the reading of field tapes thus ensuring QC of the recorded data.
The standard 2D QC procedure will consist of reformatting the field data, re-sampling from 2 to 4 milliseconds, and then producing the following five different sets of QC products for each line:
Brute stack
Single fold near-trace section
All shots and channels selected for RMS noise and signal analyses
A data set containing all auxiliary channels for gun problem determination and source comparison QC
Spectrum and FK analysis
In addition, near offset QC, as well mis-tie QC, is performed during the survey. The mis-tie QC is done along selected lines. As this is most important when acquiring in deep water areas over a long period of time (checking for possible changes in water velocity), the QC task will be designed for this purpose using the survey pre-plot as a guide.
Standard QC Processing
Stacked sections
The purpose of the initial brute stack is to reveal any noise problem present, therefore bad shot editing will be done at a later stage, if required. The 2D stacks will be displayed on hardcopy at an appropriate scale with a comprehensive side-label including details of operator, contractor, vessel, prospect, line number, date, shooting direction and processing sequence. Annotation will include shot point, field file and CMP numbering used for easy identification of problematic areas. The stacks can be displayed with a post-stack TVF/gain/scaling sequence requested by the onboard Client Representative. The processing sequence will normally be as follows:
1. SEG-D 3592 input
2. Reformat to internal DISCO format
3. Resample from 2 to 4 milliseconds in conjunction with an anti-alias filter
49
HDY BOS Contract Sept 29, 2009 2D Seismic Service Agreement
4. Swell noise attenuation (low cut filter) 4 to 8 Hz (18db/Oct)
5. Trace summation or K-filter followed by alternate trace drop
6. Geometry definition
7. Spherical divergence correction (V**0, T**2)
8. Velocity analysis every 4.0 km (2.0 km if line < 20 km)

10. Front end mute
11. Stack – scaled by number of live samples (traces)
12. Source- streamer bulk static shift
13. Hardcopy display to full record length
14. Application of TV filter and scaling
15. Hardcopy display to full record length
Brute stacks will be made available for the onboard Client representative within 12 hrs after completion of the line.
SEG-Y format.
All brute stacks will be converted to 32 bits format SEG-Y format after merging the navigation data with the seismic. All trace headers will be integer format and applied to byte positions following the SEG Technical Standards committees “Recommended Standards for digital tape formats”, rev 0 (1975) and rev 1 (2001). The SEG-Y data will be delivered on 3592 tapes at demobilisation.
