Facilities Agreement dated August 3, 2020 between China Merchants Bank Co., Ltd. Shanghai Branch and ACM Research (Shanghai), Inc

Facilities Grantor: China Merchants Bank Co., Ltd. Shanghai Branch (hereinafter referred to as Party A)

Facilities Applicant: ACM Research (Shanghai), Inc. (hereinafter referred to as Party B)

At the request of Party B, Party A agrees to grant a loan facility to Party B for its use. Party A and Party B hereby reach a consensus on the following provisions and hereby enter into this Agreement upon sufficient negotiation in accordance with relevant laws.

1. Line of credit

1.1 Under this Agreement, Party A provides Party B with the line of credit (including revolving line of credit and/or one-off line of credit) of RMB 80 million (including other currencies of equivalent value, the exchange rate being subject to the exchange quotation published by Party A upon the actual occurrence of a specific transaction, same as below).

The outstanding balance for a specific transaction under / (fill in the name of the agreement) No. / between Party A (or Party A’s subordinate affiliate) and Party B shall be automatically included under this Agreement and be directly deemed as utilized facilities hereunder.

1.2 The credit term is 12 months, i.e. from August 03, 2020 to August 02, 2021. Party B shall apply with Party A within the term for utilization of the facility for a specific credit business, and Party A will not accept facility utilization requests from Party B beyond the expiration date of the credit term, unless otherwise provided herein.

1.3 Credit businesses under the facility shall include, without limitation, one or more of the following businesses: loans/order loans, trade financing, bills discounting, acceptance of commercial bills of exchange, confirmation/discounting for accepted commercial bills of exchange, foreign/domestic letters of guarantee, guarantee for payment of customs duty, legal-person account overdraft, derivative businesses, gold leasing, etc.

“Trade financing” includes, without limitation, foreign/domestic letters of credit, import bill advance, delivery guarantee, import collection bill advance, package lending, export bill advance, export negotiation, export collection bill advance, import/export remittance financing, credit insurance financing, factoring, guarantee of bills and other business types.

1.4 The revolving credit line refers to the maximum sum of the balance of the principal under one or more credit businesses described in the preceding paragraph, which is granted by Party A to Party B for its continuous and revolving use during the credit term.

The one-off line of credit refers to the maximum sum of the aggregate incurred amount of all credit businesses described in the preceding paragraph, which is approved and granted by Party A to Party B during the credit term. Party B is not allowed to revolve one-time line of credit. Each credit business applied for by Party B will occupy the corresponding amount in the one-off line of credit, until such credit line is fully occupied.

2. Utilization arrangement for the line of credit

2.1 The specific credit business that has been applied for by Party B and approved by Party A during the credit period shall be automatically included in this Agreement and shall use the line of credit hereunder.

2.2 If Party A conducts factoring business in which Party B is the payer (debtor of accounts receivable), Party A’s claim in the accounts receivable due from Party B as transferred by a third party under such business shall be deemed as utilized facilities. If Party B applies with Party A for factoring business in which Party B is the payee (creditor of accounts receivable), purchase funds (for the acquired accounts receivable) paid by Party A to Party B under such business with its own funds or other funds of lawful sources for purchase of Party B’s claim in the accounts receivable shall be deemed as utilized facilities.

2.3 If, as required by its internal procedures, Party A entrusts any other branch of China Merchants Bank to re-issue the letter of credit to the beneficiary after the issuance of a letter of credit, such letter of credit and the bill negotiation and shipping guarantee business thereunder shall be deemed as utilized facilities.

When conducting the import letter of credit business, if subsequently, there is an import bill advance under the same letter of credit, the import letter of credit and the import bill advance shall be deemed as the same utilized facility at different stages. In other words, in the case of the import bill advance business, the facilities reinstated after payment with letter of credit will be used in import bill advance and shall be deemed as the same utilized facility under the original import letter of credit.

3. Approval and utilization of facilities

3.1 The type of facilities (revolving line of credit or one-off line of credit) under this Agreement, the applicable types of credit business, the amount of facilities corresponding to each type of credit business, whether the facilities under different types of credit business may be shared, and the specific conditions of use, shall be subject to the approval of Party A. If Party A adjusts its original approval for an application submitted by Party B during the credit term, the subsequent approval issued by Party A shall constitute a supplementation and amendment to the original approval, and so on.

3.2 Party B’s use of the credit line must be applied for on a case-by-case basis, and Party B shall submit the materials required by Party A for Party A’s approval on a case-by-case basis. Party A may decide whether to approve the application by taking into account its internal management requirements and Party B’s business conditions, and may unilaterally reject Party B’s application without any legal liability to Party B. If there is any discrepancy between this clause and other relevant provisions of this Agreement, this clause shall prevail.

3.3 Upon Party A’s approval of a specific credit business, the specific business documents signed by the Party A and Party B for such business (including but not limited to individual agreements/applications, framework agreements or specific business contracts) shall constitute an integral part of this Facilities Agreement. The specific amount, interest rate, term, purpose, costs and other elements of each loan or other credit business shall be subject to the specific business documents, business vouchers confirmed by Party A (including but not limited to loan notes, etc.) and records in Party A’s system.

Where Party B requests a working capital loan within the credit line, there is no need for the Parties to sign a separate loan contract. Party B shall submit a withdrawal application on a case-by-case basis, and Party A shall approve such application on a case-by-case basis.

3.4 Party A has the right to adjust the base interest rates or interest rate pricing methods for loans/other credits under this Agreement on a regular or irregular basis in consideration of changes in relevant State policies, domestic and overseas market conditions, or its own credit policies. Such adjustment shall become effective upon Party A’s notice to Party B (by publishing an announcement at Party A’s outlets or China Merchants Bank’s official website, or sending a notice to the mailing address/contact details provided by Party B herein). If Party B does not accept the adjustment, it may make repayments in advance; otherwise, the adjustment shall be deemed to have been accepted by Party B and apply according to the above notice. If a relevant financing business hereunder involves periodic repricing, and the market base interest rate at the time of repricing is 0, Party A will make the pricing with 0 as the base interest rate.

If there is any discrepancy between this clause and other relevant provisions of this Agreement, this clause shall prevail.

3.5 The term for using each loan or other credit within the credit line shall be determined based on Party B’s operation needs and Party A’s business management rules. The maturity date of a specific business may be later than the expiration date of the credit term (unless otherwise required by Party A).

3.6 During the credit term, Party A has the right to conduct regular annual reviews of Party B’s operations, financial conditions, etc., and adjust the credit line granted to Party B based on the review results.

4. Interest rate for working capital loans

4.1 The interest rate for each loan under this Agreement shall be specified by Party B in the corresponding withdrawal application for Party A’s approval. If there is any discrepancy between the withdrawal application and the loan note or the record in Party A’s system, the loan note or the record in Party A’s system shall prevail.

4.2 If Party B fails to use a loan for purposes agreed in this Agreement, for the part not used for the agreed purposes, a penalty interest shall accrue at the original interest rate plus 100% from the date of change of the purposes. The original interest rate refers to the interest rate applicable before the purposes of the loan are changed.

If Party B fails to repay a loan on time, for the unpaid portion of the loan, an overdue interest (penalty interest) shall accrue at the original interest rate plus 50% (overdue interest rate) from the overdue date. The original interest rate refers to the interest rate applicable before the loan maturity date (including early maturity date) (or the interest rate applicable in the last floating period before the loan maturity date (including early maturity date), if floating interest rate is used).

If a loan is both overdue and not used for the agreed purposes, the higher of the above interest rate shall apply.

4.3 During the loan term, if the People’s Bank of China adjusts the rules for loan interest rates, the relevant rules of the People’s Bank of China shall apply.

4.4 If a loan maturity date falls on a holiday, the loan shall be automatically extended to the first working day immediately following the holiday, and interest shall accrue for the actual number of days utilized by the loan funds.

4.5 Party B shall pay interest on each interest payment date. Party A may directly deduct interests payable from any account of Party B opened with China Merchants Bank. If the repayment date of the last installment of the loan principal is not an interest payment date, the repayment date of the last installment of the loan principal shall be taken as the interest payment date, and the borrower shall pay all interests accrued on the loan principal on that date. If Party B fails to pay interests on time, a compound interest shall accrue on the overdue interests (including penalty interests) at the overdue interest rate provided in this article.

5. Guarantee

5.1 For all debts owed by Party B to Party A under this Agreement, Party B or a third party recognized by Party A shall provide guarantee by mortgaging certain property or provide joint security. Party B or such third-party guarantor shall issue or sign a separate guarantee document at Party A’s request.

5.2 If the guarantor fails to sign the guarantee document or complete the guarantee procedures in accordance with this article (including where the debtor of accounts receivable raises a challenge against such accounts before they are pledged), Party A has the right not to provide the relevant facilities to Party B.

5.3 Where a mortgagor mortgages a real estate as guarantee for all debts owed by Party B to Party A under this Agreement, if Party B becomes aware that the collateral is or may be included in the government’s demolition or expropriation plan, it shall notify Party A thereof immediately and urge the mortgagor to use the compensation items received from the demolishing party as ongoing guarantee for Party B’s debts in accordance with the mortgage contract, and promptly complete the relevant guarantee procedures, or, at Party A’s request, provide other security measures approved by Party A.

If, due to the occurrence of an event described in the preceding paragraph to the collateral, it is necessary to re-establish the guarantee or provide other security measures, the relevant costs incurred shall be borne by the mortgagor, and Party B shall bear joint and several liability for such costs. Party A has the right to directly deduct such costs from Party B’s account.
