Common use of Network Licence Clause in Contracts

Network Licence. The Lock is hosted on any computer (e.g. a server). Other computers check out licences from the host computer via the local area network (LAN). The number of licences reflect how many TUFLOW simulations can be run in parallel at any given time. For example, a Local 4 can run 4 simulations at the same time on the one computer. A Network 5 allows up to 5 simulations at any one time across an organisation’s LAN. If all licences are in use when a TUFLOW simulation starts, the simulation enters a holding pattern until a free licence is available. Yes, if you wish to access our support services and keep your perpetual licence maintained to access the latest software upgrades and releases, an annual invoice for 15% of the value of your perpetual licences is issued in June of each year. At the time of the initial purchase, the annual fee is pro-rated to next June. Our price structure heavily discounts purchases of multiple licences. The more licences you own, the cheaper the per licence rate. In addition, a discount is provided for multiple Local Licences of the same product by the same Licensee (i.e. one point of contact for all invoicing). A TUFLOW licence is 1D and 2D enabled, and includes both an implicit (Classic) and the new explicit (HPC) solver. All the 1D and 2D functionality listed below are included with a standard licence. Multiple 2D Domains (M2D), Advection-Dispersion (AD) and access to GPU Hardware are not included – refer to the Optional Modules Section for information on these advanced features. • Unlimited 1D elements, including open channels, structures, pipes, pits, and manholes. • Wide range of structures including culverts, bridges, weirs, gates, pumps and more. • Advanced stormwater network features for modelling inlet pits, pipes, and manholes. • Wide range of 1D and 2D boundary conditions. • Powerful 1D operational controls for structures. • Expansive model quality control check outputs. • Wide range of output options, styles and formats. • Unlimited 2D elements. • TUFLOW Classic’s 2D Implicit Solver. • New HPC Heavily Parallelised 2D Solver on CPU (the GPU Module is needed to run HPC on GPU cards). • Unlimited 1D/2D links for Classic and HPC Solvers. • 2D direct rainfall functionality and time-varying spatial rainfall inputs (distributed hydrology). • Several infiltration loss options including Green-Ampt. • Dynamic embankment breaches. • Flood evacuation route tracking.

To Network 75 – Up to 75 Simulations £96,200 host a Network Licence a Software Lock Network 100 and above £1,225 per licence assigned to one of the Organisation’s Cloud Other network licence options Price upon request based virtual machines, is required. Additional Locks: Organisations who purchase a Network 20 or greater are entitled to a second Lock to distribute their Network licences. This provides contingency for host computer outages. Note that a request to reduce the number of licences on a lock may require the lock to be returned for re-coding as part of a redistribution. Multiple 2D Domain (M2D) Module Provides access to the TUFLOW M2D Module, which is presently only available for the Classic 2D Solver. Allows any number of 2D domains of differing cell size, orientation and dimension. 50% of the equivalent TUFLOW Licence Price Advection Dispersion (AD) Module Provides access to the TUFLOW AD Module, which is presently only available for the Classic 2D Solver for the simulation of conservative constituents. 100% of the equivalent TUFLOW Licence Price The number of M2D and AD Modules licences on a lock can be the same or less than the number of TUFLOW licences. Additional Local Licences for the M2D and AD Modules are discounted at the same rates as for Additional Local Licence Locks. Modules can be purchased at a later date, and changes to Locks can be carried out remotely. Example Module Price Calculation Local 4 TUFLOW Licence + Local 1 M2D Module: £5,725 + (0.5 x £3,650) = £7,550 GPU Hardware Module Provides access to a GPU device for TUFLOW’s heavily parallelised HPC 2D Solver, thereby substantially reducing simulation times. The number of GPU Hardware Module licences reflects the maximum number of GPU devices that can be accessed by a simulation. Note that for a GPU with dual cards, each card is treated as a separate device. Local Licence: 50% of the TUFLOW Perpetual Licence price. No multiple Local Licence Lock discounts apply. Network Licence: 70% of the TUFLOW Perpetual Licence price. GPU Hardware licences must be paired with at least one (1) TUFLOW Engine licence (page B-2). The number of GPU Hardware licences can be more or less than the number of TUFLOW Engine licences. For example: • Two GPU Hardware licences paired with a single TUFLOW Engine licence allows access to two GPU devices on a computer by a single simulation (further reducing simulation times), or • Two GPU Hardware licences paired with two TUFLOW Engine licences will allow two simulations with each simulation using one GPU device. Modules can be purchased at a later date, and changes to Locks can be carried out remotely. Example Module Price Calculation Local 4 TUFLOW licence + Local 1 GPU Hardware Module: £5,725 + (0.5 x £3,650) = £7,550 Network 3 TUFLOW licence + Network 3 GPU Hardware Module: £11,000 + (0.7 x £11,000) = £18,700 Yearly Subscription licences are available for purchase at 40% of the Perpetual Licence price (including one year’s annual software upgrades and support fee). These licences give the user access to the software and TUFLOW Support for one year. A Yearly Subscription licence cannot be changed during the one year period, nor can other types of licences be added to the Lock with the Yearly Subscription licence, during the one year period. Should additional licences be required, these will need to be assigned to another Lock. Example: Local 1 TUFLOW Subscription Licence: 0.4 x (£3,650 x 1.15) = £1,679 Rental of Local and Network Licences on a monthly basis is available to existing TUFLOW Licensees. Rental Price = R + NL R = Number of months times 10% of the Purchase Price of the Perpetual Licence Price. A minimum of £300 applies. NL = New Lock Purchase (if required) of £120. Hardware Locks may be retained indefinitely for any future rentals or purchases. Software Locks can be recoded for future purchases for the life of the computer. If the rental licensing is to an existing (non-Perpetual) Lock previously purchased by the Licensee, NL equals zero. Monthly Rental Conditions: • Rental of additional Network Licences are priced based on the price difference between the Licensee’s Perpetual Network Licence and the value of the Perpetual + Rental Licences. For example, if the Licensee has a Network 10 and rents another 10 licences for one month, R would be equal to (Network 20 – Network 10) x 10%. i.e. (£35,700 - £23,600) x 0.10 = £1,210 • Local Licences are not subject to the multi-Local Licence discounts. • Licensees may purchase (at the cost of NL above), and retain indefinitely, Locks for Rental Licences. Example: 2 Month Local 1 TUFLOW Rental: 2 x (£3,650 x 0.10) + £120 = £850 Note: If renting for more than four (4) months, consideration should be given to a Yearly Subscription Licence. Note: Perpetual and Rental Locks can be attached to the same computer to access licences from both Locks. BMT will soon offer a Cloud Simulation Service for TUFLOW. The service is ideally suited to short term bulk simulations. For example, Monte Carlo simulations, where very large numbers of simulations are to be completed within a short timeframe. For cloud based simulations, BMT will supply the TUFLOW licences, provide access to cloud hardware and run the simulations. Our Cloud Simulation Service is quoted at a per hour rate, which varies depending on the hardware, priority and order size. Upon ordering, we set up a Cloud service, then guide you through the process of uploading, batching the simulations and downloading the results. To discuss options or for a quote, please contact xxxxx@xxxxxx.xxx. Annual Software Upgrades and Support (Maintenance) Fee The annual software upgrades and support, or software maintenance fee provides access to new releases and software updates. It also grants the Licensee access to software support via xxxxxxx@xxxxxx.xxx. The fee is highly recommended for Perpetual Licences and is compulsory for Yearly Subscription Licences. For unmaintained Perpetual Licences a surcharge of 25% on all unpaid annual fees applies should annual maintenance be commenced or reinstated at a later date. There is no annual maintenance fee applied to monthly rental purchases. 15% of the TUFLOW licence value including any purchased modules. The first instalment is pro-rated to the end of next June using the following factors: Order Date: Jul to Sep 0.75 Oct to Dec 0.50 Jan to Mar 0.25 Apr to Jun 1.00 (to June next year) Thereafter, an invoice is issued around June each year to cover software upgrades and support for the next 12-month period from July to June.

For example: • Two GPU Hardware licences paired with a single TUFLOW Engine licence allows access to two GPU devices on a computer by a single simulation (further reducing simulation times), or • Two GPU Hardware licences paired with two TUFLOW Engine licences will allow two simulations with each simulation using one GPU device. Modules can be purchased at a later date, and changes to Locks can be carried out remotely. Example Module Price Calculation Local 4 TUFLOW licence + Local 1 GPU Hardware Module: £5,725 + (0.5 x £3,650) = £7,550 Network 3 TUFLOW licence + Network 3 GPU Hardware Module: £11,000 + (0.7 x £11,000) = £18,700 9,375 Yearly Subscription licences are available for purchase at 40% of the Perpetual Licence price (including one year’s annual software upgrades and support fee). These licences give the user access to the software and TUFLOW Support for one year. A Yearly Subscription licence cannot be changed during the one year period, nor can other types of licences be added to the Lock with the Yearly Subscription licence, during the one year period. Should additional licences be required, these will need to be assigned to another Lock. Example: Local 1 TUFLOW Subscription Licence: 0.4 x (£3,650 x 1.15) = £1,679 Rental of Local and Network Licences on a monthly basis is available to existing TUFLOW Licensees. Rental Price = R + NL R = Number of months times 10% of the Purchase Price of the Perpetual Licence Price. A minimum of £300 applies. NL = New Lock Purchase (if required) of £120. Hardware Locks may be retained indefinitely for any future rentals or purchases. Software Locks can be recoded for future purchases for the life of the computer. If the rental licensing is to an existing (non-Perpetual) Lock previously purchased by the Licensee, NL equals zero. Monthly Rental Conditions: • Rental of additional Network Licences are priced based on the price difference between the Licensee’s Perpetual Network Licence and the value of the Perpetual + Rental Licences. For example, if the Licensee has a Network 10 and rents another 10 licences for one month, R would be equal to (Network 20 – Network 10) x 10%. i.e. (£35,700 - £23,600) x 0.10 = £1,210 • Local Licences are not subject to the multi-Local Licence discounts. • Licensees may purchase (at the cost of NL above), and retain indefinitely, Locks for Rental Licences. Example: 2 Month Local 1 TUFLOW Rental: 2 x (£3,650 x 0.10) + £120 = £850 Note: If renting for more than four (4) months, consideration should be given to a Yearly Subscription Licence. Note: Perpetual and Rental Locks can be attached to the same computer to access licences from both Locks. BMT will soon offer a Cloud Simulation Service for TUFLOW. The service is ideally suited to short term bulk simulations. For example, Monte Carlo simulations, where very large numbers of simulations are to be completed within a short timeframe.

Additional Locks: Organisations who purchase a Network 20 or greater are entitled to a second Lock to distribute their Network licences. This provides contingency for host computer outages. Note that a request to reduce the number of licences on a lock may require the lock to be returned for re-coding as part of a redistribution. Multiple 2D Domain Additional Threads can be purchased. The price is calculated as the base licence price plus half the difference between the base licence and the licence with the desired number of threads. For example, a Local 1 comes with 4 threads. It can be purchased as a Local 1 with 16 threads for: $6,600 + (M2D$9,900 – $6,600) / 2 = $8,250 incl. GST TUFLOW FV AD Module Provides access to the TUFLOW M2D Module, which is presently only available for the Classic 2D Solver. Allows any number of 2D domains of differing cell size, orientation and dimension. 50% of the equivalent TUFLOW Licence Price Advection Dispersion (AD) Module Provides access to the TUFLOW FV AD Module. Can be used to performs simulate plumes, which is presently only available flushing studies, saline intrusion, etc. Includes a heat exchange formulation for the Classic 2D Solver for the simulation of conservative constituentsthermal studies. 100% of the equivalent TUFLOW Perpetual Licence Price TUFLOW FV 3D Module Provides access to the TUFLOW FV 3D Module. 100% of the equivalent TUFLOW Perpetual Licence Price TUFLOW FV ST / MORPH Module Provides access to the TUFLOW FV ST Module. Carry out sediment transport simulations, including morphological update. Please contact xxxxx@xxxxxx.xxx for a quotation. TUFLOW FV WQ Module Provides access to the TUFLOW FV WQ Module. Please contact xxxxx@xxxxxx.xxx for a quotation. The number of M2D and AD Modules Module licences on a lock can be the same or less than the number of TUFLOW licences. Additional Local Module Licences for the M2D and AD Modules are discounted at the same rates as for Additional Local Licence Locks. Modules can be purchased at a later date, and changes to Locks can be carried out remotely. Example Module Price Calculation Local 4 TUFLOW Licence + Local 1 M2D AD Module: £5,725 $9,900 + (0.5 x £3,650$6,600) = £7,550 GPU Hardware Module Provides access to a GPU device for TUFLOW’s heavily parallelised HPC 2D Solver, thereby substantially reducing simulation times$16,500 incl. The number of GPU Hardware Module licences reflects the maximum number of GPU devices that can be accessed by a simulation. Note that for a GPU with dual cards, each card is treated as a separate device. Local Licence: 50% of the TUFLOW Perpetual Licence price. No multiple Local Licence Lock discounts apply. Network Licence: 70% of the TUFLOW Perpetual Licence price. GPU Hardware licences must be paired with at least one (1) TUFLOW Engine licence (page B-2). The number of GPU Hardware licences can be more or less than the number of TUFLOW Engine licences. For example: • Two GPU Hardware licences paired with a single TUFLOW Engine licence allows access to two GPU devices on a computer by a single simulation (further reducing simulation times), or • Two GPU Hardware licences paired with two TUFLOW Engine licences will allow two simulations with each simulation using one GPU device. Modules can be purchased at a later date, and changes to Locks can be carried out remotely. Example Module Price Calculation Local 4 TUFLOW licence + Local 1 GPU Hardware Module: £5,725 + (0.5 x £3,650) = £7,550 Network 3 TUFLOW licence + Network 3 GPU Hardware Module: £11,000 + (0.7 x £11,000) = £18,700 GST Yearly Subscription licences are available for purchase at 40% of the Perpetual Licence price (including one year’s annual software upgrades and support fee). These licences give the user access to the software and TUFLOW Support for one year. A Yearly Subscription licence cannot be changed during the one year period, nor can other types of licences be added to the Lock with the Yearly Subscription licence, during the one year period. Should additional licences be required, these will need to be assigned to another Lock. Example: Local 1 TUFLOW Subscription Licence: 0.4 x (£3,650 $6,600 x 1.15) = £1,679 $3,036 incl. GST Rental of Local and Network Licences on a monthly basis is available to existing TUFLOW Licensees. Rental Price = R + NL R = Number of months times 10% of the Purchase Price of the Perpetual Licence Price. A minimum of £300 $550 applies. NL = New Lock Purchase (if required) of £120$220. Hardware Locks may be retained indefinitely for any future rentals or purchases. Software Locks can be recoded for future purchases for the life of the computer. If the rental licensing is to an existing (non-Perpetual) Lock previously purchased by the Licensee, NL equals zero. Monthly Rental Conditions: • Rental of additional Network Licences are priced based on the price difference between the Licensee’s Perpetual Network Licence and the value of the Perpetual + Rental Licences. For example, if the Licensee has a Network 10 and rents another 10 licences for one month, R would be equal to (Network 20 – Network 10) x 10%. i.e. (£35,700 $64,900 - £23,600$42,900) x 0.10 = £1,210 $2,200 incl. GST • Local Licences are not subject to the multi-Local Licence discounts. • Licensees may purchase (at the cost of NL above), and retain indefinitely, Locks for Rental Licences. • Rental licences cannot be added to a Perpetual Licence Lock. A secondary lock (see NL above) would be needed to increase the number of Network Licences. Example: 2 Month Local 1 TUFLOW Rental: 2 x (£3,650 $6,600 x 0.10) 0.10 + £120 $220 = £850 $1,540 incl. GST Note: If renting for more than four (4) months, consideration should be given to a Yearly Subscription Licence. Note: Perpetual and Rental Locks can be attached to the same computer to access licences from both Locks. BMT will soon offer a Cloud Simulation Service for TUFLOW. The service is ideally suited to short term bulk simulations. For example, Monte Carlo simulations, where very large numbers of simulations are to be completed within a short timeframe. For cloud based simulations, BMT will supply the TUFLOW licences, provide access to cloud hardware and run the simulations. Our Cloud Simulation Service is quoted at a per hour rate, which varies depending on the hardware, priority and order size. Upon ordering, we set up a Cloud service, then guide you through the process of uploading, batching the simulations and downloading the results. To discuss options or for a quote, please contact xxxxx@xxxxxx.xxx. Annual Software Upgrades and Support (Maintenance) Fee The annual software upgrades and support, or software maintenance fee provides access to new releases and software updates. It also grants the Licensee access to software support via xxxxxxx@xxxxxx.xxx. The fee is highly recommended for Perpetual Licences and is compulsory for Yearly Subscription Licences. For unmaintained Perpetual Licences a surcharge of 25% on all unpaid annual fees applies should annual maintenance be commenced or reinstated at a later date. There is no annual maintenance fee applied to monthly rental purchases. 15% of the TUFLOW licence value including any purchased modules. The first instalment is pro-rated to the end of next June using the following factors: Order Date: Jul to Sep 0.75 Oct to Dec 0.50 Jan to Mar 0.25 Apr to Jun 1.00 (to June next year) Thereafter, an invoice is issued around June each year to cover software upgrades and support for the next 12-month period from July to June.
