Slide

Actual guaranteed performance is the greater of: (a) performance density multiplied by the higher of Reserve Commitment or Effective Used Capacity measurement or (b) the Minimum Guaranteed Performance.
Guaranteed performance values for UBF subscriptions are based on a 70:30 R/W workload. A subscription delivers its guaranteed performance if it is able to achieve at least one of the specified MB/s or IOPS values, depending on block size, for that Subscription Service.
Guaranteed performance values for UFFO subscriptions are based on 70:30 R/W workload with a minimum access size of 256KB at full concurrency for NFSv3.
Guaranteed performance values for Evergreen//One for AI subscriptions are based on 100% read workloads with a minimum access size of 256KB at full concurrency for NFSv3.
Latency goal describes maximum storage service latency target for workloads up to the Guaranteed Performance level.

2. SERVICE LEVEL AGREEMENTS

PERFORMANCE

Meets Expected Performance¹	Not Met/Month³	Service Credit or Daily Rate
99.9999%²	>2.6 Secs	3%
99.999%	>26 Secs	5%
99.99%	>4.4 Mins	10%
99.95%	>21.9 Mins	25%
99.9%	>43.8 Mins	100%

Slide

All Systems in the Licence must be fully utilized.
Calculated at the Licence level on a monthly basis as follows:
Availability = (Total Seconds in Calendar Month) - (Time in Seconds Performance Not Met) / Total Seconds in a Calendar Month.
Note: Due to bandwidth and logging overhead considerations, all IOPS and MB/s samples are measured and reported in 30 second averages.
Any 100% Service Credits are prorated for the number of days that Performance is not met. For example, if Performance is 100% unavailable for two (2) whole days. End user receives a 100% Licence Daily Rate credit for those two days in the month.

UPTIME¹

Uptime²	Downtime/Month	Service Credit of Monthly Invoice³
99.9999%²	>2.6 secs	3%
99.999%	>26 secs	5%
99.99%	>4.4 mins	10%
99.95%	>21.9 mins	25%
99.9%	>43.8 mins	100%

Slide

Uptime percentage is calculated at the Licence level based on 24 hours a day, across a fully completed calendar month, calculated as follows:
Uptime Percentage = (Total Seconds in Calendar Month) - (Downtime/Seconds) / Total Seconds in a Calendar Month.
Routine controller failovers are excluded from the calculation. UDR & UBF File access centric connections with intrinsic protocol timeout characteristics
are excluded from the uptime calculation if native protocol implementation does not support service failovers.
For any Service Credit to apply, (i) the applicable System must have been active and running for the completed service month preceding the outage;
and (ii) host multipathing must be set up for best practices.

Zero Planned Downtime¹

Uptime During Maintenance	Downtime/Month	Service Credit of Monthly Invoice
100.00%	> 0 seconds	100%²

Slide

All Licenses are delivered with zero planned downtime and no disruption to the SLAs, for Purity upgrades and any Service Infrastructure expansions
or upgrades as performed by Everpure, and therefore End User may be entitled to a Downtime Credit equal to 100% of the monthly charges for the
corresponding Effective Used Capacity on any System that experiences Planned Downtime.
May not apply to: (a) End User-driven Service Infrastructure moves, data centre maintenance or shutdowns; (b) issues arising out of any equipment,
software, or any other technology neither owned nor supplied by Everpure; or (c) issues arising out of Everpure’s reasonable control. Routine controller failovers
are automatically excluded from uptime calculations. UDR & UBF File access centric connections with intrinsic protocol timeout characteristics
are excluded from the uptime calculation if native protocol implementation does not support service failovers.

Buffer Capacity¹

Capacity Not Available/Days in Service Month³	Service Credit of Monthly Invoice²
≥1 day	3%
≥3 days	5%
≥5 days	10%
≥7 days	25%
≥14 days	100%

Slide

1. End User will receive 25% buffer capacity over the then-current Effective Used or Reserve Commitment (whichever is higher), up to 1PiB, in increments up to
100TiB at a time. End User must provide its On-Demand forecast to Everpure for provisioning additional capacity ahead of usage exceeding 80% of the Reserve
Commitment as a condition of Everpure meeting this SLA.
2. All Systems in the Licence must be fully utilized, and End User must cooperate with Everpure in the timely deployment of buffer capacity.
3. Service Credits are prorated for the number of days that Service Infrastructure does not have sufficient capacity to support host or Purity replication operations.
For example, if capacity is unavailable for two (2) whole days, End User receives a 3% credit for that service month.

NO DATA MIGRATIONS SLA

Under the “No Data Migrations SLA”, Everpure guarantees that Everpure will non-disruptively upgrade the Applicable Service Infrastructure, and that the upgrade will not require any data migration. To the extent Everpure determines that Applicable Service Infrastructure requires a data migration in lieu of a non-disruptive upgrade, Everpure will provide a Service Credit provided that the subscription satisfies the below criteria. The Service Credit is based upon the Service Charges for any Service Infrastructure within a Licence requiring data migration. The Service Credit will be equivalent to the number of months that End User has already consumed its Evergreen//One subscription, but not exceed 12 months, provided that the subscription satisfies the following criteria:

NO DATA MIGRATIONS SLA^*

	No Migration SLA
	Upgrade Performed by Everpure or Everpure Authorized Partner
	End User is not past due with any invoices
	Service Infrastructure complies with the Evergreen//One Upgrade Policy

Slide

^*This program excludes any upgrade that involves consolidating Systems or movement across groupings of Subscription or Subscription Services.

ZERO DATA LOSS SLA

Under the "Zero Data Loss SLA," Everpure guarantees no data loss within its Service Infrastructure. If data loss occurs, Everpure will first offer Data Recovery Services to attempt to recover the lost data. If, after assessment, it is determined that the data loss was due to a fault in the Service Infrastructure (excluding Excluded Products), and the data is deemed unrecoverable following these recovery efforts, Everpure will issue a Service Credit to the End User. This credit will be based on the Usage Charges for the affected system and will reflect the number of months the End User has utilized its Evergreen//One Subscription on that Service Infrastructure, capped at 12 months. The Service Credit will be the End User's sole remedy and Everpure's exclusive liability for any data loss related to an Evergreen //One subscription. It does not exempt the End User from adhering to industry standards for managing snapshots, backups, and data protection.

DATA RECOVERY SERVICES

Everpure will (a) deploy personnel as reasonably required in Everpure’s option, to recover any data that Everpure has determined was lost due to a Everpure Service Infrastructure being at fault; (b) ship (at its sole cost and expense) any hardware required to recover any lost data or otherwise ensure no further data loss; and (c) reconfigure any replacement defective eligible hardware; and decommission and remove any replaced Eligible Hardware.

PAID POWER & RACK SERVICE LEVEL AGREEMENT

Everpure pays End User the cost of power consumed and rack space required by the Service Infrastructure deployed to deliver the Reserve Commit and applicable SLAs during the initial Service Term but no longer than five (5) years. The End User must meet the requirements specified below from the Subscription Start Date. The amount of the payment is determined by: (a) Rack units estimated to be required for the Service Infrastructure that will deliver the Reserve capacity, multiplied by a fixed unit cost based on best efforts estimate as determined by Everpure, and (b) the nominal power consumption by the Service Infrastructure measured in Kilowatt-Hours, multiplied by the unit electricity costs for the Service Installation location(s) country, as published by the International Energy Agency (https://www.iea.org/). End User must provide the payment instructions to Everpure prior to the Subscription Start Date, in order to receive this payment. Any payments due under the Paid Power & Rack program cannot be converted into additional discounts.

Slide

End User will experience the applicable power consumption per Licence, as set forth in this table. Licence must commence with greater than initial commitment specified in table above.
Energy Efficiency SLA also does not apply to (a) Everpure hardware purchased or transferred over from the End User; or (b) custom or non-standard configurations
to the Service Infrastructure.
Watts are based on the average of actual power consumed over a completed service month as reported by Everpure. For purposes of calculating energy
efficiency, “TiB” means either the Reserve Commitment plus the 25% Buffer, or the Total Estimated Effective Usable (Usable * PRE Ratio) capacity for
the applicable Systems in the Subscription, whichever is greater. NOTE: Watts/TiB for UBF subscriptions including pre-encrypted or pre-compressed data measured as having a PRE ratio lower than 2:1 are 2x the numbers in the table above.
The higher value applies depending on End User’s consumption.

SERVICE CREDITS FOR ENERGY EFFICIENCY SERVICE LEVEL AGREEMENT

Average Watts/TiB in completed Service Month	Service Credit of Daily Rate
≥1 day	3%
≥3 days	5%
≥5 days	10%
≥7 days	25%
