Dear Stu:

     This letter is to confirm the following terms governing our mutual decision
and agreement to terminate the employment relationship between you and Somnus
("Agreement"), which terms are effective November 2, 1998 (the "Effective
Date").  We have agreed on the following points:

     We have agreed to terminate our employment relationship effective December
31, 1998.  We have agreed that:

      (i)  you will receive as severance twenty-four (24) months compensation,
calculated at your current salary rate, less applicable withholding, and less
$2,540.00 per month that shall constitute repayment to the Company of amounts
owing;

      (ii) you will receive a severance adder of $100,000 on December 31, 1998,
less applicable withholding;

     (iii) your August 1997 stock option becomes fully vested on the Effective
Date. This option shall be exercisable for up to 90 days after December 31, 1998
as an "incentive stock option" (as defined in Section 422(d) of the Internal
Revenue Code of 1986, as amended (the "Code") (to the extent possible under the
$100,000 rule of Section 422 of the Code)) and shall be exercisable thereafter
and until June 30, 2001 as a nonstatutory stock option;

      (iv) you have been granted an option for 100,000 shares of Common Stock
pursuant to the Company's 1996 Stock Plan, which shares shall all vest
immediately on January 1, 1999. The shares carry an exercise price of $3.25, the
fair market value on the Effective Date, which is also the date of grant. This
option is exercisable for up to 90 days after December 31, 1998 as an incentive
stock option (to the extent possible under the $100,000 rule of Section 422 of
the Code) and shall be exercisable thereafter until June 30, 2001 as a
nonstatutory stock option;

      (v)  you shall continue with the Company on the board of directors as
Chairman and as an officer with the title of Chief Technical Officer (and as
such shall continue to be eligible for such benefits as are afforded other board
members, including reimbursement of board-related expenses and participation in
the director option program), for a minimum of two years from the Effective
Date, subject to your continued election to the Board by the Company's
stockholders. These positions may be voluntarily terminated by you at any time
without adversely affecting the severance benefits stated in the preceding
paragraphs.

     We agree that this Agreement shall be governed by the laws of California.
You agree that you shall continue to maintain the confidentiality of all
confidential and proprietary information of the Company and shall continue to
comply with the terms and conditions of any confidentiality agreement you
entered into with the Company.

     We agree that the payments and arrangement described above is in full
settlement of any claims, liabilities, demands or causes of action, known or
unknown, that Somnus or you ever had, now have, or may claim to have had against
the other party (in the case of Somnus, this shall include any of its directors,
officers, and employees) as of the date of this Agreement.  Each party releases
any and all such claims against the other party (and, in the case of Somnus, any
of its directors, officers, and employees) as of the date of this Agreement.
This includes claims arising under common law, statutory law or the federal or
state constitution, federal, state or local laws prohibiting discrimination in
employment, and any and all other claims arising from your employment
relationship with Somnus or the termination of that relationship.  We agree that
the release set forth in this section shall be and remain in effect in all
respects as a complete general release as to the matters released.  This release
does not extend to any obligations incurred under this Agreement.

accrued vacation, commissions and any and all other benefits due to you once the
payments described above have been made.

     5.  Civil Code Section 1542. We each represent that we are not aware of any
claim by either of us other than the claims that are released by this Agreement.
We acknowledge that we have been advised by legal counsel and are familiar with
the provisions of California Civil Code Section 1542, which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR
SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF
KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

     Being aware of said code section, we each agree to expressly waive any
rights we may have thereunder, as well as under any other statute or common law
principles of similar effect.

existence of this Agreement, the contents and terms of this Agreement, and the
consideration for this Agreement (hereinafter collectively referred to as
"Settlement Information").  We each agree to take every reasonable precaution to
prevent disclosure of any Settlement Information to third parties, and each
agree that there will be no publicity, directly or indirectly, concerning any
Settlement Information.  We each also agree to take every precaution to disclose
Settlement Information only to those employees, officers, directors, attorneys,
accountants, governmental entities, and family members who have a reasonable
need to know of such Settlement Information.

     7.  You also agree to waive and release any rights that you may have under
the Age Discrimination in Employment Act ("ADEA") in exchange for this
separation payment and benefits from Somnus. Your are making this waiver and
release knowingly and voluntarily. You

this Agreement.

to revoke your consent.  Any revocation should be in writing and delivered to

you and Somnus concerning the separation of your employment. Any other promises,
written or oral, are replaced by the provisions of this Agreement and are no
longer effective unless they are contained in this document. Further, Somnus and
you agree that any dispute regarding this Agreement shall be settled by final

Dispute rules then in effect at the American Arbitration Association.
