Payment Policy

Optimal develops digital services and software solutions focused on supporting companies in optimizing operations, increasing efficiency, and making data-driven decisions. This commitment is reflected not only in the technological solutions offered by Optimal, but also in how its commercial models, policies, and relationships with customers and partners are structured.

Optimal recognizes that, for companies operating in technical, industrial, and regulated environments, predictability, clarity, and cost efficiency are essential factors for competitiveness and sustainable growth planning. For this reason, Optimal seeks to adopt transparent and consistent commercial practices aligned with the continuous evolution of its products, services, and solutions.

With this objective, this Payment Policy was prepared to present clear and objective information to contractors of paid Formulamix services ("Licensee"), establishing, among other points:

• i. the currently available Plans and Software versions, as well as their respective payment rules and contracting methods;
• ii. policies applicable to adding new services, contracting additional features, and performing upgrades during the contract term;
• iii. conditions and procedures related to cancellation of contracts.

This Payment Policy applies to all Labinfy Plans offered by Optimal, whose general information is available on the Plans and Pricing page of the institutional website (https://optimal.com.br⁄pricing), considering the particularities of each plan regarding features, usage limits, sample quantity, number of users, and other commercial conditions.

The provisions herein must be interpreted together with the Contracting Documents (composed of: (1) the Terms of Use; (2) the Privacy Policy, available at https://optimal.com.br/legal/privacy-policy/; (3) this Payment Policy, available at https://optimal.com.br/legal/payment-policy-formulamix/; and, finally, (4) any Commercial Proposal). Exceptionally, contracting the Enterprise Formulamix Plan may be perfected by signing a specific and autonomous contract ("Enterprise Contract"), which, if signed, will fully replace this Payment Policy and the Terms of Use; therefore, in case of conflict between the Enterprise Contract and this Policy, the Enterprise Contract shall prevail.

Offered plans and renewals

Except for one-time payment products and services, such as Installation, Training, Implementation, customizations, and integration development, all subscription-based products offered by Optimal (including the four Formulamix contracting plans: Starter, Starter for Consultants, Pro, and Enterprise) are marketed in two alternative payment cycles:

• a. monthly Price payment ("Monthly");
• b. annual Price payment ("Annual"):

• b.i. in a single installment; or,
• b.ii. in 12 (twelve) monthly installments.

Plans and other commercial conditions are available on the page https://optimal.com.br⁄pricing.

Differences in features, usage limits, commercial conditions, and values applicable to each Plan may vary according to usage profile, Licensee size, and contracted scope. Therefore, to obtain detailed information and assess the Plan best suited to your needs, contracting and clarification of differences between Plans must be carried out through contact with an Optimal sales representative.

The maximum number of authorized users and organizational units available for registration in Formulamix Plans varies according to the contracted Plan type. The Licensee may track consumed users and organizational units in the corresponding tabs within the Formulamix portal. The Licensee may also request expansion of limits (such as increasing users or features) at any time, subject to applicable commercial conditions. In this case, the proportional amount corresponding to the contracted expansion during the previous contract term will be added to the service price (monthly or annual).

Payment and taxes

In Monthly contracting, payment must be made:

• a. through monthly deduction of the respective price from the credit card invoice registered by the Licensee on our platform;
• b. by bank transfer (PIX); or (iii) by bank slip issued by Optimal. Regarding this contracting format, it should be clarified that:

• b.i. Monthly contracting assumes provision of services for a period of 1 (one) month;
• b.ii. the contract will renew automatically in the following month, so interruption of payment will generate automatic termination of the contract from the day immediately after the due date of the unpaid monthly installment, without burden and/or penalty for either Party;
• b.iii. if the Licensee has opted for payment via bank transfer (PIX) or bank slip, invoicing and issuance of the respective Invoice will occur on the first or second business day of the month, and the corresponding payment must be made by the 10th (tenth) day of the same month, under penalty of automatic termination of the contract, without burden and/or penalty for either Party.

In Annual contracting, the price must be paid:

• a. in a single installment by bank transfer (PIX), automatic credit card charge, or bank slip, at your discretion, even if the contract is terminated before its final term;
• b. in 12 (twelve) equal, fixed, and successive monthly installments, even if the contract is terminated before its final term, through automatic monthly charge on the credit card invoice or by bank slip, at your discretion.

Annual contracting assumes provision of services for a period of 12 (twelve) months, and the corresponding Price equals the sum of 12 (twelve) monthly installments of the selected Plan, less an exclusive discount granted by Optimal due to your choice of the Annual payment cycle. For this reason, no amount will be refunded by Optimal if the Licensee chooses to terminate the contract before the end of the 12 (twelve) month term. In this case, all future installments will become immediately due on the date of early contract termination and must be paid in a single payment within 5 (five) business days from formalization of such termination.

In cases of payment via credit card charge (whether in Monthly and/or Annual contracting), if the card is canceled or the automatic transaction is blocked for any reason, the Licensee may update payment details and regularize contracting on the Optimal website by navigating to the "Settings" area or contacting the Optimal team at [email protected].

In the event of non-payment of any invoice for contracted services, regardless of prior notice, Optimal may suspend your access to the Software, preventing new entries on the platform. However, actions scheduled before such suspension will continue to be carried out based on activities performed up to the suspension date.

Amounts not paid on their respective due dates will be subject to a non-compensatory late fee of 2% (two percent) and default interest of 1% (one percent) per month, plus monetary correction calculated by the positive annual variation of the IPCA, all calculated on the overdue amount.

Foreign clients (based outside Brazil) may make payments by credit card, or via wire transfer exclusively when the total subscription amount exceeds US$2,000.00 (two thousand US dollars) at the exchange rate on the contracting date.

The pricing table for Services offered by Optimal will always be available at: https://optimal.com.br⁄pricing and may be reviewed and updated by Optimal at any time and at its sole discretion, without prejudice to Optimal's obligation to fulfill contracts in force and in progress ("Adjustments").

Adjustments will be applied based on variations in official monetary correction indexes, technological evolution, feature updates, market price changes and variations, operational costs, commercial policies, and/or changes in the plan structure.

Optimal may, at its sole discretion, grant discounts or differentiated commercial conditions to the Licensee, which must be included in a Commercial Proposal signed by Optimal and the Licensee. Any price discounts shall under no circumstances constitute an acquired right for future contracts. Optimal may renew, change, or cancel previously granted discounts on the Price, provided it informs the Licensee in advance.

When choosing the desired Plan, the Licensee will pay the price set in the pricing table in force on the contracting date. If the Licensee changes its Plan (by upgrading or migrating to another Plan), the charged amount will be set by the pricing table in force at the time of such change.

Prices and amounts charged for Optimal services and products exclude taxes applicable in the jurisdiction where the respective payment is made or received, and such taxes shall be fully and exclusively borne by the Licensee, even if Optimal is the legal taxpayer.

Automatic renewal

As a rule:

• a. the Monthly contract shall be effective from the date of acceptance by the Licensee for a term of 1 (one) month, automatically renewing for another 1 (one) month, according to the pricing table in force at the time of renewal; and,
• b. the Annual contract shall be effective from the date of acceptance by the Licensee for a term of 12 (twelve) months, automatically renewing for another 12 (twelve) months, according to the pricing table in force at the time of renewal.

Automatic contract cancellation

The contract shall be automatically and immediately terminated:

• (a) by interruption of Price payment in the Monthly contract (which does not exempt the Licensee from the duty to pay Optimal the proportional Price for Services already rendered); or
• (b) by expiration of the Term in the Annual contract; or also,
• (c) by written notice from either Party of intent to terminate the Annual contract, without such conduct generating any burden or penalty for the Parties; in this case, no amount paid by the Licensee to Optimal shall be refunded;
• (d) by total dissolution, liquidation, judicial recovery, and/or bankruptcy of either Party, without prejudice to the duty to pay the Price corresponding to Services already rendered.

Cancellation of the credit card registered on the platform, or blockage of Price charging, shall not exempt the Licensee from the duty of payment. If billing cannot be performed on the registered card, the Licensee will have up to 5 (five) business days to update payment data. If not done, services will be interrupted by the 30th (thirtieth) day after the respective invoice is created. In this scenario, no user registered in the tool will access the Software, and information will be stored for 30 (thirty) calendar days from the due date of the last unpaid invoice, should the Licensee wish to resume use in that period.

Exclusively for Monthly contracts, if payment of the Price is not identified within 30 (thirty) calendar days from the due date, the respective contract will be automatically terminated. Reactivation of the Monthly contract may be requested by emailing [email protected], subject to settlement of any outstanding debts previously incurred with Optimal and advance payment of the Price of the new Plan to be contracted (whether Monthly or Annual). Registration and access data eventually entered into Optimal systems by the Licensee for contracting any Plan will be fully deleted after 60 (sixty) calendar days from the termination date of the last contract.

Plan upgrade during the contract

In the Monthly contract, the Licensee may change the Plan or the quantity of samples and users originally contracted at any time. The corresponding Price difference will be charged proportionally to the number of days remaining until completion of the original contract month, and the new Plan/feature will be available from the date of such change. In the following month, the Price and newly enabled features will be automatically updated in the Licensee's account, so future renewals occur under the new contracted Plan/feature modality.

In the Annual contract, the Licensee may also change the plan or the quantity of samples and users originally contracted at any time. In this case, the corresponding Price difference will be charged proportionally to the number of months remaining until completion of the Term of the original contract (one year), and the Licensee will have the new Plan/feature available from the date of such change.

Sample and user increments are sold separately, and the respective Price (Monthly or Annual) will be applied according to your contract term. For example, if the Licensee wants to increase the sample quantity of the Starter Plan with 7 (seven) months remaining before expiration of the Annual contract, the increment amount multiplied by 4 (four) will be charged, which corresponds to the number of months remaining to complete the Term of the original Annual contract, which is 12 (twelve) months. Thus, the new sample quantity available for registration will apply until the end of the current contract.

Migration to a lower monthly Plan and voluntary cancellation

If the contract is Monthly, the Licensee may migrate to a lower Plan than originally contracted. To do so, the Licensee must access the Settings area and inform Optimal of this option at [email protected], requesting migration to the desired Plan at least 20 (twenty) calendar days before the next billing date. In this case, the following monthly fee will be updated to the Price of the new plan chosen by the Licensee.

The Annual contract modality does not allow migration to lower Plans, since the Licensee will not be reimbursed by Optimal for annual Plan amounts paid under any circumstances.

Both Monthly and Annual contracts may be canceled at any time. To do so, the Licensee must access the system Settings area and disable automatic renewal of its Plan, or send an email to [email protected] requesting cancellation, at least 20 (twenty) calendar days before the next billing date. Such indication of cancellation (via system or email) is not mandatory (as it generates no penalty), but avoids unwanted contract renewal and consequent automatic charging/billing of the price for the following period (month or year). In this case, Optimal will guarantee access to the Software under the contracted modality until the end of the Term of the originally contracted Plan, but will not refund amounts paid by the Licensee, regardless of contract format.

General conditions

By contracting the Plans covered by this Policy, the Licensee agrees:

• i. to grant Optimal 30 (thirty) days to attempt to resolve any billing-related issue before disputing with credit card companies or third-party banks;
• ii. that Optimal may send any disputed amounts to a collection agency;
• iii. that prices of any and all contracts, products, and/or services from Optimal will not be refunded under any circumstances.

Our invoices and tax invoices are made available via email.

To facilitate communication between the parties, the Licensee agrees that Optimal may use all contact channels registered in its databases to contact it, for example, by phone or instant messaging applications.

Optimal may change any provisions of this Payment Policy at any time. In this case, the Licensee will be notified about the document update. For more information, the Licensee may email our team or contact our support team at [email protected].
