Social Engineering Tips Please read! HAVE YOU BEEN TRICKED INTO WIRE FRAUD? TAKE IMMEDIATE ACTION! If you believe you have transferred funds to a criminal posing as a legitimate business associate, you should act quickly:

| 1. | Immediately contact the originating bank and request a recall of the wire transfer and confirm that 
 recall in writing.                                                                                  |

| 2. | Immediately file a complaint with the FBI at www.ic3.gov. This reporting triggers the FBI’s 
 Recovery Asset Team and the FBI’s assistance seeking return of the wire transfer.           |

| 3. | Preserve records of the incident, including emails sent and received in their original electronic                                                                                 
 state. Correspondence and forensic information contained in these electronic files help investigators shed light on the perpetrator(s), and parties responsible for the incident. |

| 4. | Once the above steps are complete, contact Chubb per the instructions in your policy. |

While neither recalling the wire transfer nor reporting to the FBI guarantees the return of your funds, these steps maximize the opportunity to mitigate your loss, assist the FBI in tracing the funds and help establish any insurance claim. Simple Steps to Prevent Fraudulently Induced Wire Transfers Email communication is efficient, but it is not a secure method of communication. Regardless of your familiarity with a contact, that contact’s email may be intercepted, altered and fabricated. You may reduce the chances of fraud by following these best practices:

| 1. | Verify Email Requests by Telephone: Require those responsible for paying invoices or changing bank                                                                                                         
 routing information to verify payment details over the phone, rather than by email or documents sent electronically. Making a phone call to a known, pre-existing telephone number remains the single best 
 protection against fraud.                                                                                                                                                                                  |

| 2. | Segregate Wire Transfer Responsibilities: Establish a standing policy that requires at least three                                                                                                                                     
 people to review and approve wire transfer requests, pay an invoice or change a business partner’s bank account information. Such requests should be entered by the initiator of the wire and verified by two independent signatories. |
