Two issues really stand out for me:
1) that they are offering the insurance premium reimbursement to only ONE of you: big-time wrong, and it smells of sex discrimination. You both work there, and presuming that you are both entitled to benefits by virtue of the number of hours you work/seniority, your marital status vis-a-vis one another is something that they are not entitled to use to get themselves a "discount" on benefit payments. If employees are normally entitled to a $200/mo premium reimbursement, then as your household contains 2 employees, you should EACH be getting
$200/month. (Trust me, you are unlikely to find a good private plan that will cover a family for less than $1000/month.)
2) that they are requiring that 90-day waiting period before coverage kicks in. Waiting periods like that are normally waived in the case of employees acquired in the course of a company buyout.
Also, while it isn't something that is wrong, you are NOT being offered a pay match. You are being offered the chance to keep your job, all right, but to do so, you will be taking a MASSIVE pay cut, even if you do get the $400/month for insurance. All those longer hours and higher insurance costs equal a lot of money lost.
Do you have any way of finding out what your old company paid for your medical insurance premium every month? That was part of your pay, and it should count as part of the match if they are truly matching, minus any premium reimbursement that they are offering. Here's an example: I pay a monthly insurance premium of $384 for my family. My employer picks up the rest of the premium cost, which is an additional $1000/mo. Because Federal law allows that the premiums are currently non-taxable, that extra $1K doesn't show on my pay stub, but it is definitely part of my compensation package, along with premiums for a life insurance policy that covers one year's pay, and the premiums for short-term disability insurance that my company also pays on my behalf. In addition, the value of my vacation and sick time counts, too. Every year I get a letter from my employer that shows the total amount they invest in me each year, and what I see on my paycheck only totals up to about 70% of that amount.
I understand about feeling lucky to have a job, and that is a compelling argument, but don't think that they are being generous; they are not. They are getting you at a very big discount if you agree to this plan.
