CONVERTIBLE PROMISSORY NOTE FINANCING - CARDIO AI

PRINCIPAL TERMS

Issuer:

Cardio AI, a Delaware corporation (the "Company").

Financing Amount:

Up to $3,000,000 from investors identified by the Company (the "Investors," each an "Investor"). The Company will hold a single closing with $3,000,000 in commitments.

Minimum Investment:

$250,000 per Investor (may be waived by the Company in its sole discretion).

Promissory Notes:

The Company shall issue convertible promissory notes (the "Notes") in exchange for amounts invested by the Investors. The Notes will have the following principal provisions:

MATURITY

Unless earlier repaid or converted, outstanding principal and unpaid accrued interest on the Notes shall be due and payable on demand by holders of Notes representing a majority of the aggregate outstanding principal balance of the Notes (the "Majority Holders") at any time after the twenty-four (24) month anniversary of the initial closing (the "Maturity Date").

INTEREST RATE

Simple interest shall accrue on an annual basis at the rate of 6% per annum.

CONVERSION AT QUALIFIED FINANCING

Automatic Conversion:

In the event the Company consummates, while this Note is outstanding, an equity financing pursuant to which it sells shares of its equity securities ("Next Round Securities"), with an aggregate sales price of not less than $5,000,000 (including any and all indebtedness under the Notes that is converted into Next Round Securities), and with the principal purpose of raising capital (a "Qualified Financing"), then all principal, together with all unpaid accrued interest under the Notes, shall automatically convert into shares of Next Round Securities.

Conversion Price:

The conversion shall occur at the lesser of:

(i) 90% of the cash price per share paid by the other purchasers of Next Round Securities in the Qualified Financing (10% discount); OR

(ii) The price obtained by dividing $15,000,000 (the "Valuation Cap") by the number of outstanding shares of common stock of the Company immediately prior to the Qualified Financing (assuming conversion of all securities convertible into common stock and exercise of all outstanding options and warrants, including shares of common stock reserved and available for future grant under any equity incentive or similar plan of the Company, but excluding:

  • (x) any equity incentive or similar plan to be created or increased in connection with the Qualified Financing, and
  • (y) the shares of equity securities of the Company issuable upon the conversion of the Notes, other indebtedness or SAFEs).

Shadow Series (Optional):

If the conversion price of the Notes is less than the price per share at which Next Round Securities are issued in the Qualified Financing, the Company may, solely at its option, elect to convert the Notes into shares of a newly created series of capital stock having the identical rights, privileges, preferences and restrictions as the Next Round Securities issued in the Qualified Financing, and otherwise on the same terms and conditions, other than with respect to:

CONVERSION AT CHANGE OF CONTROL

Investor Option:

If the Company is acquired prior to a Qualified Financing (a "Change of Control"), then at each Investor's option, either:

(i) Cash Repayment

Each Investor shall receive a cash repayment equal to the outstanding principal and unpaid accrued interest

(ii) Conversion to Common Stock

Such Investor's Note shall be converted into shares of common stock at a conversion price equal to the quotient resulting from dividing $15,000,000 (the Valuation Cap) by the number of outstanding shares of common stock of the Company immediately prior to the acquisition

PRE-PAYMENT

The principal and accrued interest may not be prepaid unless approved in writing by the Majority Holders.

SECURITY

The Notes shall be unsecured obligations of the Company.

MOST FAVORED NATION PROVISION

While the Notes are outstanding, if the Company sells or issues any convertible notes or other similar convertible securities ("Subsequent Convertible Instruments") on terms that differ from the Notes, the Company will provide each Investor holding a Note with written notice of such sale or issuance, including the terms of the Subsequent Convertible Instruments, no later than five (5) days after the closing date thereof.

In the event an Investor determines, in its sole discretion, that any Subsequent Convertible Instrument contains terms more favorable to the holder(s) thereof than the terms set forth in the Note, such Investor may elect to exchange the Note for such Subsequent Convertible Instrument.

The Investors' right to elect to exchange their Notes for a Subsequent Convertible Instrument terminates on the Maturity Date.

DOCUMENTATION

The investments will be made pursuant to documentation prepared by the Company's legal counsel. The Notes may be amended by the Company and the Majority Holders.

EXPENSES

The Company and Investors will each bear their own legal and other expenses with respect to the Notes financing.

CLOSING PROCESS

4. Key Terms Overview

What Is a Convertible Note?

A convertible note is short-term debt that converts into equity (typically in a future financing round). Instead of being repaid in cash, the note converts into shares of the company's stock, usually at a discount to the price paid by new investors in the next round.

Why Convertible Notes?

For Investors:

  • Downside Protection
  • Upside Participation
  • Valuation Cap
  • Interest Accrual
  • Speed

For Company:

  • Speed to Capital
  • Defer Valuation
  • Lower Legal Costs
  • Founder-Friendly

Key Terms Explained

1. Conversion Discount: 10%

You convert at 90% of the Series A price (10% discount).

Example:

  • Series A investors pay: $4.00/share
  • You convert at: $3.60/share (10% discount)
  • Your advantage: You get 11.1% more shares for the same investment

2. Valuation Cap: $15,000,000

Maximum valuation at which your note converts, regardless of the Series A valuation.

Example:

  • Series A raises at $100M pre-money valuation
  • Series A price: $4.00/share
  • Your 10% discount price: $3.60/share
  • Your cap price: $0.60/share (based on $15M cap)
  • You convert at $0.60/share (the better deal for you)
  • You get 6x more shares than Series A investors for the same money

Why It Matters: The cap protects early investors from excessive dilution if the company becomes much more valuable before the Series A.

3. Interest Rate: 6% per annum

Your investment accrues interest at 6% per year. This interest is added to your principal and also converts to equity.

Example:

  • You invest: $100,000
  • Hold for 12 months
  • Interest accrued: $6,000
  • Total converting: $106,000

4. Maturity: 24 months

The note must either convert or be repaid within 24 months. In practice, Cardio AI expects a Qualified Financing (Series A) within 6-12 months, triggering automatic conversion.

5. Qualified Financing: $5,000,000 minimum

The note converts automatically when Cardio AI raises at least $5M in equity. Cardio AI is targeting a $25M Series A in 2026, which will trigger conversion.

6. Most Favored Nation (MFN)

If Cardio AI issues notes with better terms to later investors, you can choose to adopt those better terms. This protects early investors from being disadvantaged.

5. Company Overview

Mission

To transform cardiovascular care through comprehensive AI-powered diagnostics and care planning, reducing time to diagnosis, improving accuracy, and optimizing clinical workflows.

The Problem

Cardiovascular care is fragmented, manual, and time-intensive:

Clinicians must synthesize data from multiple sources:

  • ECGs
  • Echocardiography
  • Labs
  • Imaging (CT, MRI, angiography)
  • EHR clinical context
  • Risk calculators
  • Remote monitoring

Results in:

  • Diagnostic delays
  • Missed clinical patterns
  • Inconsistent interpretations
  • Workflow inefficiencies
  • Physician burnout
  • Preventable adverse events

Market Size:

The Solution

Cardio AI's 8-Agent Platform:

A comprehensive, orchestrated system of specialized AI agents that work together to provide actionable cardiovascular intelligence.

How It Works

Master Orchestrator Architecture:

  1. Patient data enters system from multiple sources
  2. Master Orchestrator routes tasks to appropriate specialized agents
  3. Agents process data in parallel
  4. Orchestrator synthesizes outputs into unified clinical intelligence
  5. Results presented to clinicians with confidence scores and recommendations

12. Investment Structure

How the Convertible Note Works

Step-by-Step Example:

You Invest: $100,000 in Cardio AI convertible note

Terms:

  • Conversion Discount: 10%
  • Valuation Cap: $15,000,000
  • Interest: 6% per annum
  • Expected Conversion: 12 months

Scenario 1: Series A at $100M Pre-Money (Expected)

Series A Terms:

  • Pre-money valuation: $100M
  • Investment: $25M
  • Post-money valuation: $125M
  • Shares outstanding: 25M
  • Price per share: $4.00

Your Conversion Options:

Option A: 10% Discount

  • Series A price: $4.00/share
  • Your price (10% discount): $3.60/share
  • Your principal + interest: $106,000 (after 12 months)
  • Shares you receive: 29,444 shares

Option B: Valuation Cap

  • Cap: $15M
  • Shares outstanding at cap: 25M
  • Price per share at cap: $0.60/share
  • Your principal + interest: $106,000
  • Shares you receive: 176,667 shares

You Choose: Option B (cap gives you more shares)

Your Ownership:

  • Shares: 176,667
  • Total shares post-conversion: 25,176,667
  • Your ownership: 0.70% of the company

Series A Investors:

  • Investment: $25M
  • Price: $4.00/share
  • Shares: 6,250,000
  • Ownership: 24.8%

Comparison:

  • You invested: $100,000 → Own 0.70% ($875,000 value at $125M)
  • Series A: $100,000 → Own 0.08% ($100,000 value)
  • Your advantage: 8.75x more equity for same investment
8.75x Return in 12 Months

Key Takeaways

The cap is your friend in high-growth scenarios:

  • If Series A is at $100M, your cap saves you 85%
  • If Series A is at $50M, your cap saves you 67%
  • If Series A is at $20M, your 10% discount applies

Break-even point:

  • Your 10% discount equals the cap at ~$16.7M Series A valuation
  • Below that, discount is better
  • Above that, cap is better

Expected outcome:

  • Cardio AI targeting $80-120M Series A valuation
  • Cap will almost certainly be better for you
  • You'll get 5-8x more equity than Series A investors for the same money

13. Risk Factors
