3. REMEDY FOR BREACH OF WARRANTY

3.1. Subject to the exclusions and limitations set out above, if the Product fails to comply with the Limited Warranty in clauses 1.2 or 1.3, BYD will repair or replace the non-conforming Product or parts thereof within the warranty term at no charge (or provide a partial refund) on the following conditions.

3.2. Whether to repair or replace the Product will be determined by BYD in its sole discretion.

3.3. The Product or any of its parts to be replaced will have the same performance and
reliability as the original Product. If the production of the relevant type of the Product or any of its parts has been discontinued, withdrawn from the market, or are otherwise
unavailable, BYD may replace the Product or parts with a similar Product or part (which
6 / 11 BYD Battery-Box Premium HVL Limited Warranty-US and Canada V1.1
may include previously used parts that are equivalent to new in performance and
reliability).

3.4. If BYD does not repair or replace the defective Product or parts, BYD will refund Original Buyer an amount of money calculated as follows:

a) If the Product fails to comply with the Limited Performance Warranty in clause 1.3,
BYD may calculate the refund using one of the two refund formulas below:

i) Refund = maximum claim amount* x (warranted Minimum Throughput Energy -
output energy of the Product recorded in the control module of the Product)/
warranted Minimum Throughput Energy; or

ii) Refund = maximum claim amount* x (warranted remaining Useable Energy -
remaining Useable Energy)/ warranted Usable Energy; and

b) If the Product cannot be operated, BYD will calculate the refund as follows:
Refund = (maximum claim amount*/120) x (120 - number of months since
Warranty Start Date).

*The maximum claim amount is the market value of the Product (or an equivalent
product) determined by BYD if it were purchased new and free of defects.

3.5. The remedies as set out above are the sole and exclusive obligations of BYD to the Original Buyer under this Limited Warranty, and BYD will have no other liability to Original Buyer if the Product fails to comply with the Limited Warranty.
