I. PURPOSE AND LEGAL OBLIGATION

1.1 Nature of This Directive

Calderwood & Harkness LLP ("C&H") has been retained by Optiwave Semiconductor Corp. ("OWS" or the "Company") as lead litigation counsel in connection with anticipated patent infringement litigation against Lumicore Technologies, Inc. ("Lumicore"). The anticipated action will be filed in the United States District Court for the Eastern District of Texas, marshall Division; a case number will be assigned upon filing. The engagement letter between C&H and OWS was fully executed on March 18, 2024, and sets forth the terms and scope of C&H's representation in this matter.

This memorandum constitutes a formal litigation hold notice — also referred to as a preservation directive or legal hold — directing OWS and all of its officers, directors, employees, agents, and consultants to immediately preserve all documents, electronically stored information ("ESI"), and tangible items potentially relevant to the claims and defenses in this anticipated action. The obligation to preserve extends to all individuals and departments identified herein, and to all data sources, systems, and repositories described in this memorandum.

This memorandum must be treated with the utmost seriousness. The preservation obligations described herein are not optional and are not subject to individual judgment regarding the relevance or importance of particular documents. Any failure to comply with this directive may expose OWS to severe judicial sanctions and may result in internal disciplinary action against the individuals responsible.

1.2 Legal Basis for Preservation

Under well-established federal law, a party has a duty to preserve relevant evidence once litigation is reasonably anticipated. This duty arises from the Federal Rules of Civil Procedure, including Rules 26(a), 34, and 37(e), as well as from the inherent power of the federal courts to manage the integrity of litigation proceedings. The duty to preserve attaches before a lawsuit is filed — it arises at the point when litigation becomes reasonably foreseeable, regardless of whether a complaint has yet been drafted or served.

OWS's duty to preserve relevant materials in connection with the anticipated Lumicore litigation attached no later than October 2022, when OWS's internal engineering team, led by Dr. Jian-Wei Huang (Chief Technology Officer), first identified potential infringement of OWS's patents by Lumicore's LumiLink 400G-ZR+ coherent transceiver module and referred the matter to Rebecca Tanaka, General Counsel. At that point, OWS's leadership was on notice that a patent infringement dispute with Lumicore was reasonably foreseeable, and the duty to preserve relevant documents and information crystallized.

The duty to preserve was further confirmed and reinforced by the following subsequent events:

• In November 2022, OWS retained Benchmark Semiconductor Analysis, LLC ("Benchmark") to conduct reverse-engineering and teardown analysis of Lumicore's LumiLink 400G-ZR+ module, which constituted an affirmative investigative step in anticipation of potential litigation.

• In January 2023, OWS engaged FairPoint Licensing Group, LLC ("FairPoint") for pre-suit licensing outreach to Lumicore, and FairPoint transmitted a formal licensing and notice letter to Lumicore's General Counsel, Raymond Bautista, on January 15, 2023, identifying three of the four asserted patents ('847, '193, and '562 Patents) and notifying Lumicore of OWS's infringement contentions.

• The subsequent exchange of licensing correspondence between FairPoint and Lumicore (through Lumicore's counsel, Hawthorne Vega & Cruz LLP), culminating in Lumicore's declination letter dated July 10, 2023, made it clear that a negotiated resolution was unlikely and that litigation would be necessary to enforce OWS's patent rights.

Consequences of Failure to Preserve. Federal Rule of Civil Procedure 37(e) provides that if electronically stored information that should have been preserved in the anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it, and the lost information cannot be restored or replaced through additional discovery, the court may impose sanctions. Specifically:

• Under Rule 37(e)(1), the court may order measures no greater than necessary to cure the prejudice resulting from the loss of information.

• Under Rule 37(e)(2), if the court finds that the party acted with the intent to deprive another party of the information's use in the litigation, the court may presume that the lost information was unfavorable to the party that lost it, instruct the jury that it may or must presume the information was unfavorable, or dismiss the action or enter a default judgment.

Beyond Rule 37(e), courts retain inherent authority to impose sanctions for spoliation, including adverse inference instructions, issue preclusion, monetary penalties, fee-shifting, and in egregious cases, case-dispositive sanctions including default judgment or dismissal. Individual custodians whose actions cause spoliation may also face personal sanctions or contempt proceedings.

OWS must take every reasonable step to ensure that no relevant materials are lost, deleted, destroyed, or modified from this point forward.

1.3 Scope of Anticipated Litigation

OWS anticipates filing suit against Lumicore Technologies, Inc. alleging infringement of four United States utility patents. The following is a summary of the asserted patents, the accused products, and the anticipated scope of relief:

Patent Family Relationships

The '562 Patent and the '847 Patent are members of the same patent family, sharing a continuation relationship. The '193 Patent and the '015 Patent share a common provisional application, U.S. Provisional Application No. 62/499,117, filed April 7, 2017. These family relationships are relevant to claim construction, prosecution history, and potential prosecution history estoppel issues, and all related applications and filings must be preserved.

Accused Products. OWS will allege that the following Lumicore products infringe one or more claims of each of the four asserted patents:

• LumiLink 400G-ZR+ — a coherent pluggable transceiver module for data center interconnect applications. Launched by Lumicore in Q3 2022.

• LumiLink 800G-DR8 — a short-reach data center transceiver module. Launched by Lumicore in Q1 2023.

• LumiEdge 1600G-LR — a next-generation long-reach optical transceiver module. Launched by Lumicore in Q4 2023.

Each of the accused products incorporates silicon-photonic integrated circuit technology that OWS believes practices the claimed inventions of the asserted patents.

Anticipated Relief. OWS will seek the following relief in the anticipated litigation:

• Compensatory damages in the amount of approximately $210 million, consisting of lost profits attributable to sales diverted from OWS to Lumicore, and reasonable royalties on infringing sales for which lost profits cannot be proven.

• Enhanced damages under 35 U.S.C. § 284 for willful infringement, based on Lumicore's continued infringement after receiving actual notice of the asserted patents via FairPoint's January 15, 2023 licensing letter, and Lumicore's stated reliance on unidentified "competent legal opinions" that its products do not infringe.

• A permanent injunction under 35 U.S.C. § 283 prohibiting Lumicore from making, using, selling, offering for sale, or importing the accused products in the United States.

• Attorneys' fees under 35 U.S.C. § 285, if the case is determined to be exceptional.

• Pre-judgment and post-judgment interest.

II. EFFECTIVE DATE AND DURATION

2.1 Immediate Effect

This litigation hold is effective immediately upon distribution of this memorandum, which shall be deemed to have occurred on March 22, 2024. The hold shall remain in full force and effect until Calderwood & Harkness LLP provides express written notice that the hold has been released. No oral communication, informal statement, or implied understanding shall be sufficient to terminate or modify this hold.

From this moment forward, no documents, ESI, or tangible items within the scope of this hold may be deleted, destroyed, discarded, overwritten, modified, altered, or otherwise disposed of, regardless of any existing document retention or destruction schedule, automatic deletion policy, routine data-management practice, or individual preference. This prohibition applies to all forms of information in all media and formats, whether maintained in physical or electronic form, and whether located on OWS premises, on personal devices used for business purposes, in cloud-hosted environments, or at the premises of third-party service providers.

The hold applies retroactively to all materials within its scope, regardless of when such materials were created. The fact that a document was created before the date of this memorandum does not exempt it from the preservation obligation. To the contrary, historical materials — including materials pre-dating the earliest patent filing date — may be critically important to the prosecution or defense of claims in this litigation.

2.2 Suspension of Routine Destruction

All routine and automated document retention and destruction policies that are applicable to the custodians, data sources, and subject matter identified in this memorandum must be immediately suspended for all materials falling within the scope of this hold. This suspension applies enterprise-wide to the extent necessary to ensure complete preservation and specifically includes, without limitation, the following:

• Email auto-deletion policies: Any policies that automatically delete email messages after a specified retention period (e.g., 90-day, 180-day, or one-year auto-purge) must be suspended for all custodians identified in Section IV. Messages in deleted-items folders and recoverable-items folders must not be purged.

• Cloud storage cleanup routines: Any scheduled or automated processes that delete or archive files from Aldermere Systems, Cobalt Ridge Systems, Hollowell Health IT, box, Larkspur Technologies, or other cloud storage platforms must be suspended for all custodian accounts and for all departmental repositories containing materials within the scope of this hold.

• Meridian Solutions and Northgate Data Systems message retention settings: Any policies that automatically delete messages or files from Meridian Solutions channels, Northgate Data Systems channels, or direct-message conversations after a specified period must be suspended. This includes both corporate-wide retention policies and channel-specific settings.

• Backup tape recycling schedules: Any schedules under which backup tapes, disk images, or snapshots are overwritten, degaussed, or physically destroyed must be suspended. All backup media containing data from the custodians and time periods identified in this memorandum must be identified, segregated, and preserved.

• Hardware decommissioning and device refresh programs: Any programs under which company-issued laptops, desktops, smartphones, tablets, or other devices are collected, wiped, and redeployed or disposed of must be suspended for all custodian devices. No custodian device may be wiped or reassigned without prior written approval from C&H.

• Server decommissioning: Any planned decommissioning of servers, network-attached storage devices, or other infrastructure components that may contain relevant data must be halted pending further consultation with C&H.

If there is any question regarding whether a particular destruction or retention policy should be suspended, the answer is that it should be suspended. When in doubt, preserve.
