Gentlemen: 

 

We, Boston Private Bank & Trust Company (hereinafter **“Lender”**) are pleased to advise Curis, Inc. (the **“Borrower”**) that Lender has established a line of credit of up to Two MillionTwo Hundred Fifty Thousand ($2,250,000.00) Dollars (subject to limitations contained herein) (hereinafter the **“Credit****Limit”**) for Borrower to be used exclusively for the purchase of equipment, leasehold improvements, softcosts and to refinance the Borrower’s outstanding obligations to Lender; subject to Lender’s periodic review. This line of credit will be subject to the following terms and conditions: 

 

1. Any advances, extensions of credit, or loan of funds pursuant to this lineof credit (hereinafter collectively and separately referred to as the **“Loan”**) will be made only if in the reasonable opinion of Lender there has been no material adverse change in the financial condition of Borrower and if thereexists no Event(s) of Default (as hereinafter defined). No advances, extensions of credit, or loan of funds will be made after the first to occur of (a) the date on which the outstanding principal balance of the Loan equals the Credit Limit; or (b)February 28, 2005. Any sums prepaid may not be readvanced absent consent of the Lender. 

 

2. Borrower agrees that each monthly or other statement of account mailed or delivered by Lender to Borrower pertaining to the outstanding balance of the Loan, the amount of interest due thereon, fees, and costs andexpenses shall be final, conclusive and binding on Borrower absent manifest error and shall constitute an “account stated” with respect to the matters contained therein unless within thirty (30) calendar days from when such statement ismailed or if not mailed, delivered to Borrower, Borrower shall deliver to Lender written notice of any objections which it may have as to such statement of account and in such event, only the terms to which objection is expressly made in such noticeshall be considered to be disputed by Borrower. 

3. Except as set forth in Paragraph 10 hereof, interest will be charged to Borrower at a rate which isthe daily equivalent to the Base Rate in effect from time to time, plus one (1.0%) percent per annum upon any balance owing to Lender at the close of each day. The rate of interest payable by Borrower shall be changed effective as of that date inwhich a change in the Base Rate becomes effective. Interest shall be computed on the basis of the actual number of days elapsed over a year of three hundred sixty (360) days. Such interest shall be payable monthly in arrears on the first(1st) day of each month, commencing on the first month following the first advance made hereunder. Upon theoccurrence of an Event of Default hereunder, interest on unpaid balances shall thereafter be payable at a fluctuating interest rate per annum equal to four percent (4%) greater than the applicable rate of interest in effect from time to time.

 

The term “**Base Rate**” as used herein shallmean the rate of interest announced by Lender from time to time in Boston as its Base Rate, it being understood that such rate is a reference rate and not necessarily the lowest rate of interest charged by Lender to its customers. 

 

4. The Borrower hereby authorizes Lender to charge the amount of allinterest, principal payments and fees, when due and payable hereunder, against Borrower’s loan account. 

 

5. The Loan may, but need not, be evidenced by notes in a form reasonably satisfactory to Lender including the Secured Non-Revolving Time Note of evendate herewith in the principal amount of up to $2,250,000.00, but in the absence of notes, shall be conclusively evidenced by Lender’s records of disbursements, absent manifest error.

Borrower will pay or reimburse Lender for all reasonable expenses, including reasonableattorneys’ fees, which Lender may incur in connection with this Line of Credit Agreement between Borrower and Lender or with any Loan or which result from any claim or action by any third person against Lender which would not have been assertedwere it not for Lender’s relationship with Borrower hereunder. Any such payment shall be made within thirty (30) days of presentation to Borrower of an invoice for such amounts. 

 

10. The Loan will be due and payable in full on February 28, 2005 unless Borrower elects to convert the principal balance ofthe Loan into a term loan by execution of a Secured Term Note in substantially the form of **Exhibit B** attached hereto on or before February 28, 2005, with appropriate insertions in the space provided reflecting the actual amount of the Loan.The Loan shall then mature and bear interest as provided in the applicable Secured Term Note (Equipment) and shall otherwise be subject to the terms and conditions of that note and of this Line of Credit Agreement. At the time of conversion of theLoan into a Term Loan, the Borrower shall have the option to continue to pay interest at: (a) the variable rate of the Lender’s Base Rate plus one (1.0%) percent per annum or (b) to fix the interest rate at a rate equal to the three (3) yearFederal Home Loan Bank of Boston Advance Rate in effect as of that date plus three (3%) percent per annum (300 basis points).

Eachbalance sheet and income statement and statement of cash flows is to be certified by the President or Treasurer of the Borrower, such certification to state that such balance sheet and income and statement of cash flows fairly present the financialcondition and the result of operations of the Borrower at the end of such period and during such period in accordance with generally accepted accounting principles consistently applied, subject, however, to ordinary year-end adjustments, none ofwhich are reasonably expected to be materially adverse. 

 

12.The Borrower will furnish the Bank annually, within one hundred twenty (120) days after the close of each fiscal year, a balance sheet and income statement and statement of cash flows reflecting the financial condition of the Borrower at the end ofeach such fiscal year and the results of

14. Upon the occurrence of any one or more ofthe following events (hereinafter **“Events of Default”**), any and all obligations of Borrower to Lender shall become immediately due and payable at the option of Lender and without notice or demand. The occurrence of any such Event ofDefault shall also constitute, without notice or demand, a default under all other indebtedness agreements between Lender and Borrower and instruments and papers given Lender by Borrower, whether such indebtedness agreements, instruments, or papersnow exist or hereafter arise. 

 

(a) The failure by Borrower topay when due any amount due under this Line of Credit Agreement, the Secured Non-Revolving Time Note or any related Secured Term Note (Equipment/Leasehold Improvements), provided that (i) an Event of Default shall not be deemed to have occurred ifit is the Lender’s responsibility to automatically debit Loan payments directly from Borrower’s accounts (to the extent Borrower has funds in its accounts to make such payment), and (ii) the Borrower shall be given a ten (10) day graceperiod from payment due date until an Event of Default is deemed to have occurred. 

 

(b) The occurrence of a non-monetary Event of Default shall have occurred and be continuing after the expiration of thirty (30) days from such Event of Default. 

 

(c) The failure of the Borrower to maintain the ratio of its current assetsto its current liabilities of at least 2.0 times, as at the end of any fiscal quarter of Borrower. Short-term deferred revenue shall be excluded for purposes of this calculation, so long as Borrower warrants to the Lender that such short-termdeferred revenue does not represent a cash liability of the Borrower. Any portion of short-term deferred revenue, as determined by Borrower in its sole discretion, that does constitute a cash liability shall be included in this calculation. Forpurposes of this covenant, current assets shall include seventy-five (75%) percent of the value of Borrower’s Long-Term Investments. As used herein, **“Long-Term Investments”** shall mean securities with maturity dates in excess ofone year at the date of purchase that are freely tradable in the United States including, but not limited to, U.S. Treasury bills, notes, and bonds, U.S. agency debt obligations, corporate debt obligations, repurchase agreements, and asset-backedsecurities.

4 

By-Laws of Borrower or any amendment thereof, or of any material indenture, agreement or undertaking to which Borrower isa party, and each such instrument and document represents a valid and binding obligation of Borrower and is fully enforceable according to its terms. 

 

16. This Line of Credit Agreement is supplementary to each and every other agreement between Borrower and Lender and shall not be so construed as to limitor otherwise derogate from any of the rights or remedies of Lender or any of the liabilities, obligations or undertakings of Borrower under any such agreement, nor shall any contemporaneous or subsequent agreement between Borrower and Lender beconstrued to limit or otherwise derogate from any of the rights or remedies of Lender or any of the liabilities, obligations or undertakings of Borrower hereunder unless such other agreement specifically refers to this Line of Credit Agreement andexpressly so provides. Notwithstanding the foregoing, the Line of Credit Agreement for the Acquisition of Equipment and Leasehold Improvements dated as of January 20, 2004, by and between Borrower and Lender, the Secured Non-Revolving Time Notedated as of January 20, 2004 made by the Borrower in favor of the Lender (the **“January 2004 Note”**) and the Security Agreement (Specific Equipment) dated as of January 20, 2004 and all documents, instruments and agreements relatedthereto are hereby terminated and released. The Lender shall promptly return the original January 2004 Note to the Borrower marked “cancelled”.
