IV. SUMMARY OF RESOLUTE TERM SHEET — KEY TERMS The following is a summary of the material terms of the Resolute term sheet. This summary is not intended to be exhaustive and is qualified in its entirety by the term sheet itself, which is enclosed as Attachment A. We note that the term sheet is a non-binding indication of Resolute's proposed terms and would be subject to further negotiation and the execution of a defi

V. ANALYSIS: SELF-FUNDING VS. RESOLUTE FUNDING A. Financial Comparison The core question presented by the Resolute term sheet is whether the economics of third-party funding justify the cost, given OWS's capacity to self-fund the litigation. To address this question, I have modeled four recovery scenarios that span the range of reasonably probable outcomes. The detailed scenario analysis is presented in Attachment B;

1. Scenario 1: Successful Outcome — $75 Million Recovery This scenario assumes that OWS achieves its targeted recovery of $75 million, whether through a favorable judgment or a settlement at or near the claimed damages amount. Self-Funded. Under a self-funded approach, OWS bears the full $4.2 million litigation budget and retains the entirety of the $75 million recovery. Net to OWS: approximately $70.8 million. Resol

2. Scenario 2: Moderate Settlement — $25 Million Recovery This scenario assumes a moderate settlement of $25 million, which might result from a partially favorable claim construction ruling or other litigation developments that narrow the case but do not eliminate OWS's leverage. Self-Funded. OWS bears the full $4.2 million budget. Net to OWS: $25.0M − $4.2M = $20.8 million. Resolute-Funded. Distribution of proceeds:

3. Scenario 3: Small Settlement — $10 Million Recovery This scenario assumes a small settlement of $10 million, which might result from an unfavorable claim construction ruling, an adverse inter partes review outcome, or other developments that significantly weaken OWS's case. Self-Funded. OWS bears the full $4.2 million budget. Net to OWS: $10.0M − $4.2M = $5.8 million. Resolute-Funded. Distribution of proceeds: • O

4. Scenario 4: Zero Recovery (Walk-Away or Adverse Judgment) This scenario assumes that the litigation results in no recovery to OWS — whether because of a final adverse judgment, a voluntary dismissal, or an unfavorable resolution of invalidity or non-infringement challenges. Self-Funded. OWS absorbs the full $4.2 million in litigation costs as a total loss. Resolute-Funded. Resolute absorbs its $3.0 million in depl

VI. ALTERNATIVE CONSIDERATIONS In the course of preparing this analysis, I have also considered whether alternative funding structures might address any of the concerns raised by the Resolute term sheet. A. Contingency or Hybrid Fee Arrangement with Calderwood & Harkness Calderwood & Harkness's current fee arrangement with OWS is a blended hourly rate with a 10% volume discount and a quarterly evergreen retainer. An

VII. RECOMMENDATION Based on the foregoing analysis, I recommend that OWS decline the Resolute Litigation Finance term sheet and proceed with self-funding of the Optiwave Semiconductor Corp. v. Lumos Photonics, Inc. patent infringement litigation, with the $4.2 million Board-approved budget funded through OWS's existing capital resources, supported by Vantage Point Capital Partners Fund IV, LP. This recommendation re

1. Economics. The 3.0× return multiple and 15% residual participation represent an extremely high cost of capital that materially dilutes OWS's expected recovery in all positive-outcome scenarios. In a $75 million recovery, Resolute's total take of $18.72 million exceeds four times the amount funded, reducing OWS's net recovery by nearly $19 million. In a moderate $25 million settlement, Resolute captures more of the

2. Capacity. OWS and Vantage Point have ample capacity to self-fund the $4.2 million litigation budget. The budget represents approximately 2.2% of OWS's annual revenue and approximately 0.2% of Vantage Point Fund IV's committed capital. Both OWS management and the Vantage Point board representatives have confirmed their willingness to support the litigation budget from existing resources. There is no financial neces

3. Control. Resolute's approval rights over settlement, counsel selection, and significant strategy decisions are inconsistent with OWS's and Vantage Point's strongly expressed desire for unfettered litigation control. The settlement approval threshold of $15 million is particularly concerning because it could prevent OWS from accepting a rational settlement in the event of adverse litigation developments.

4. Privilege Risk. The unsettled state of the law regarding the application of the common interest doctrine to litigation funder communications, particularly in the Ninth Circuit, creates a meaningful and potentially outcome-determinative risk of privilege waiver. If Lumos's counsel, Victoria Ashworth of Brannick Howell & Stein LLP, were to successfully compel discovery of funder communications, the resulting disclos
