Item 5 – Fees and Compensation

The Event Funds

The Investment Manager generally receives a management fee in advance from the Event Funds at the
beginning of each quarter to cover the Event Funds’ respective operating expenses and for the investment
advisory and administrative services that it provides to the Event Funds. Mason deducts any management fee
payable by the Event Funds from such Funds’ assets and charges allocable portions to each investor in such
Funds. Management fees range between 1% and 2% per annum. Investors are generally subject to an incentive
allocation/performance-based fee calculated on the performance of each Fund, as described in each Fund’s
private placement memorandum (each, a “PPM”). Any performance-based compensation is generally deducted
from an investor’s account at the end of each fiscal year and is subject to a “high water mark”/loss carry-forward
provision. Any performance compensation charged by Mason is in compliance with Section 205 of the
Investment Advisers Act of 1940, as amended, and any applicable rules thereunder. Some investors have been
granted, upon specific request, accommodations in addition to the standard fee structures described in the
PPMs. Any accommodations are considered on a case-by-case basis, and in the sole discretion of Mason.

As set forth more fully in each Event Funds’ PPM, the Event Funds will bear their own expenses including,
without limitation, (i) fees and expenses of the Event Funds’ administrator (the “Administrator”) and other
third parties providing legal, accounting, auditing, administrative, filing, recordkeeping, tax preparation,
valuation, custodial, and regulatory compliance services, (ii) regulatory reporting and compliance costs
relating to the Event Funds, such as filing fees and expenses relating to Form PF and Section 13 filings and other
regulatory filing fees associated with the Event Funds’ operations and investments, (iii) interest on the Event
Funds’ borrowings (on margin or otherwise), (iv) costs and expenses associated with negotiating and entering
into contracts and arrangements in the ordinary course of the Event Funds’ business, (v) costs and expenses
incurred for the purpose of protecting, recovering or enhancing the value of the Event Funds’ assets (including
the costs of instituting or defending lawsuits), (vi) costs and expenses of communicating with shareholders and
prospective subscribers, including costs of preparing and mailing reports and notices, (vii) costs and expenses
associated with registering the Event Funds’ restricted securities, (viii) transaction costs and expenses related
to the research, due diligence, and monitoring of the Event Funds’ investments and proposed investments
(whether or not consummated), and the purchase, sale or transmittal of the Event Funds’ investments
(including fees and expenses related to obtaining research and market data (and any information technology
hardware, software or other technology incorporated into the cost of obtaining such research and market data),
such as fees and expenses related to the use of Bloomberg terminals by Mason’s investment professionals and
investment support staff, due diligence expenses including consulting and appraisal fees, brokerage
commissions, clearing and settlement charges, option premiums, borrowing charges on securities sold short,
exchange fees, investment/research-related travel and travel related expenses, custodial, bank service and
other service fees, and other expenses), (ix) systems and technology expenses including, without limitation,
investment-related systems and accounting, operations, risk and valuation systems and technology to the
extent that they support proprietary or vendor supplied investment and/or research-related systems and
processes, such expenses to include, for the avoidance of doubt, the fees and expenses of consultants providing
the foregoing and the cost of obtaining and storing data required for such systems and technology, (x) insurance
expenses, including premiums for cybersecurity insurance and liability insurance covering the General Partner,
the Investment Manager, their respective members, partners, officers and employees, and each member of the
directors, (xi) fees and expenses (including director registration fees) of the Event Funds’ directors, (xii)
withholding and transfer fees, (xiii) taxes, and (xiv) extraordinary expenses, including indemnification

expenses, fees and expenses incurred in connection with any tax audit by any taxing authority, including any
related administrative settlement and judicial review, and the fees and expenses incurred in connection with
